The incorporation of various novel therapies has resulted in a significant survival benefit in newly diagnosed and relapsed patients with multiple myeloma (MM) over the past decade. Despite these advances, resistance to therapy leads to eventual relapse and fatal outcomes in the vast majority of patients. Hence, there is an unmet need for new safe and efficacious therapies for continued improvement in outcomes. Given the role of epigenetic aberrations in the pathogenesis and progression of MM and the success of histone deacetylase inhibitors (HDACi) in other malignancies, many HDACi have been tried in MM. Various preclinical studies helped us to understand the antimyeloma activity of different HDACi in MM as a single agent or in combination with conventional, novel, and immune therapies. The early clinical trials of HDACi depicted only modest single-agent activity, but recent studies have revealed encouraging clinical response rates in combination with other antimyeloma agents, especially proteasome inhibitors. This led to the approval of the combination of panobinostat and bortezomib for the treatment of relapsed/refractory MM patients with two prior lines of treatment by the US Food and Drug Administration. However, it remains yet to be defined how we can incorporate HDACi in the current therapeutic paradigms for MM that will help to achieve longer disease control and significant survival benefits. In addition, isoform-selective and/or class-selective HDAC inhibition to reduce unfavorable side effects needs further evaluation. PMID:27226735

Clinical presentation at diagnosis and disease course of both Crohn's disease (CD) and ulcerative colitis are heterogeneous and variable over time. Since most patients have a relapsing course and most CD patients develop complications (e.g. stricture and/or perforation), much emphasis has been placed in the recent years on the determination of important predictive factors. The identification of these factors may eventually lead to a more personalized, tailored therapy. In this TOPIC HIGHLIGHT series, we provide an update on the available literature regarding important clinical, endoscopic, fecal, serological/routine laboratory and genetic factors. Our aim is to assist clinicians in the everyday practical decision-making when choosing the treatment strategy for their patients suffering from inflammatory bowel diseases.

Immunoconjugates in the management of hairy cell leukemia

2015-01-01

Hairy cell leukemia (HCL) is an indolent B-cell malignancy effectively treated but not often cured by purine analog therapy; after multiple courses of purine analogs, patients can become purine analog resistant and in need of alternative therapies. Complete remission to single-agent purine analog is often accompanied by minimal residual disease (MRD), residual HCL cells detectable by immunologic methods, considered a risk factor for eventual relapse. Several different non-chemotherapy approaches are being used to target relapsed and refractory HCL, including inhibitors of BRAF, but so far only monoclonal antibody (MAb)-based approaches have been reported to eliminate MRD in a high percentage of patients. One of the MAb-based options for HCL currently under clinical investigation involves recombinant immunotoxins, containing a fragment of a MAb and a bacterial toxin. The bacterial toxin, a highly potent fragment from Pseudomonas exotoxin, catalytically ADP-ribosylates elongation factor 2 (EF2), resulting in protein synthesis inhibition and apoptotic cell death. Recombinant immunotoxins tested in HCL patients include LMB-2, targeting CD25, and BL22, targeting CD22. An affinity matured version of BL22, termed moxetumomab pasudotox (formerly HA22 or CAT-8015) achieved high CR rates in phase I, and is currently undergoing multicenter Phase 3 testing. Phase I testing was without dose-limiting toxicity, although 2 patients had grade 2 hemolytic uremic syndrome (HUS) with transient grade 1 abnormalities in platelets and creatinine. Preclinical work is underway to identify residues on moxetumomab pasudotox leading to immunogenicity. Moxetumomab pasudotox is undergoing pivotal testing for relapsed and refractory HCL.

Remyelination Therapy in Multiple Sclerosis.

Harlow, Danielle E; Honce, Justin M; Miravalle, Augusto A

2015-01-01

Multiple sclerosis (MS) is an immune-mediated disorder of the central nervous system that results in destruction of the myelin sheath that surrounds axons and eventual neurodegeneration. Current treatments approved for the treatment of relapsing forms of MS target the aberrant immune response and successfully reduce the severity of attacks and frequency of relapses. Therapies are still needed that can repair damage particularly for the treatment of progressive forms of MS for which current therapies are relatively ineffective. Remyelination can restore neuronal function and prevent further neuronal loss and clinical disability. Recent advancements in our understanding of the molecular and cellular mechanisms regulating myelination, as well as the development of high-throughput screens to identify agents that enhance myelination, have lead to the identification of many potential remyelination therapies currently in preclinical and early clinical development. One problem that has plagued the development of treatments to promote remyelination is the difficulty in assessing remyelination in patients with current imaging techniques. Powerful new imaging technologies are making it easier to discern remyelination in patients, which is critical for the assessment of these new therapeutic strategies during clinical trials. This review will summarize what is currently known about remyelination failure in MS, strategies to overcome this failure, new therapeutic treatments in the pipeline for promoting remyelination in MS patients, and new imaging technologies for measuring remyelination in patients.

Multiple myeloma.

Multiple myeloma occurs in over 2000 new patients in England and Wales each year. It presents most frequently as bone pain and patients tend to become dehydrated and may develop renal failure. No available treatment is curative, but about two thirds of patients achieve a stable response with low dose combination chemotherapy. Combination chemotherapy including doxorubicin and carmustine with the alkylating agents cyclophosphamide and melphalan achieve a higher stable response rate than conventional treatment with melphalan and prednisone without additional haematological toxicity. These responses are associated with loss of bone pain and patients remain symptom free for months without further treatment. Relapse occurs on average in a little under two years and, though second responses are frequently obtained, the disease eventually becomes refractory. This paper looks at who should be treated and the benefits that may be expected from the treatments available. PMID:8068084

Herpes Simplex Encephalitis: an Update.

PubMed

Gnann, John W; Whitley, Richard J

2017-03-01

The goal of this review is to provide an update on current thinking regarding herpes simplex encephalitis (HSE), emphasizing new information about pathogenesis, diagnosis, and immune responses. Specific questions to be addressed are the following: (1) Is there a genetic predisposition to HSE? (2) What clinical approaches have the greatest impact on improving the long-term outcomes in patients with HSE? And (3) are there immune-mediated mechanisms that may account for relapsing HSE? Toll-like receptor 3 (TLR 3) plays an important role in innate immune responses, including generation of interferons. Multiple single-gene errors in TLR 3 interferon pathways have recently been described in children that result in increased susceptibility to HSE. Conversely, studies in both animal models and humans indicate that both cytolytic viral replication and immune-mediated responses (including cytotoxic T lymphocytes and immune mechanisms mediated by TLR 2) contribute to the pathology of HSV, suggesting possible new therapeutic approaches. In terms of treatment, data clearly indicate that a longer duration between onset of symptoms and initiation of effective antiviral therapy correlates directly with less favorable clinical outcome. Recurrent or relapsing HSE may occasionally occur, but recent observations indicate that many instances of "relapsing HSE", especially in children, are more often anti-N-methyl-D-aspartate receptor (NMDAR) encephalitis triggered by the antecedent HSV infection. Innate immune responses are critical for defense against HSV; genetic defects in this system may predispose patients to HSE. During acute HSE, exuberant immune responses may contribute to the CNS pathology, suggesting that selective immunosuppressive therapy, coupled with potent antiviral drugs, may eventually play a role in the therapeutic management of HSV. While overall clinical outcomes of HSE remain suboptimal, the initiation of high-dose acyclovir therapy as early as possible in the course of the illness provides the best chance for a patient to survive with minimal neurologic damage. Distinguishing relapsing HSE from autoimmune anti-NMDAR antibody encephalitis is critically important because therapeutic approaches will be very different.

Endemic malaria occurs across much of the vast Indonesian archipelago. All five species of Plasmodium known to naturally infect humans occur here, along with 20 species of Anopheles mosquitoes confirmed as carriers of malaria. Two species of plasmodia cause the overwhelming majority and virtually equal shares of malaria infections in Indonesia: Plasmodium falciparum and Plasmodium vivax The challenge posed by P. vivax is especially steep in Indonesia because chloroquine-resistant strains predominate, along with Chesson-like strains that relapse quickly and multiple times at short intervals in almost all patients. Indonesia's hugely diverse human population carries many variants of glucose-6-phosphate dehydrogenase (G6PD) deficiency, most of them exhibiting severely impaired enzyme activity. Therefore, the patients most likely to benefit from primaquine therapy by preventing aggressive relapse, may also be most likely to suffer harm without G6PD deficiency screening. Indonesia faces the challenge of controlling and eventually eliminating malaria across > 13,500 islands stretching > 5,000 km and an enormous diversity of ecological, ethnographic, and socioeconomic settings, and extensive human migrations. This article describes the occurrence of P. vivax in Indonesia and the obstacles faced in eliminating its transmission. © The American Society of Tropical Medicine and Hygiene.

Sentinel Node Biopsy (SNB) is a minimally invasive alternative to elective axillary lymph node dissection (ALND) for nodal staging in early breast cancer. The present study was conducted to evaluate prognostic implications of a negative sentinel node (SN) versus a positive SN (followed by completion ALND) in a closely followed-up sample of early breast cancer patients. We studied 889 consecutive breast cancer patients operated for 908 primaries. Patients received adjuvant therapy with chemotherapy, hormone therapy and eventually trastuzumab. Radiation therapy was based on tangential radiation fields that usually included axillary level I. Median follow-up was 47 months. Axillary recurrence was seen in 1.2% (2/162) of positive SN patients, and 0.8% (5/625) of negative SN patients (p = n.s.). There was an overall 3.2% loco-regional failure rate (29/908). Incidence of distant recurrence was 3.3% (23/693) for negative SN patients, and 4.6% (9/196) for positive SN patients (p = n.s.). Overall mortality rate was 4% (8/198) for positive SN patients, while the corresponding specific mortality rate was 2.5% (5/198). For patients with negative SNs, overall mortality was 4.9% (34/693), and the specific mortality was 1.4% (19/693) (p = n.s.). We did not find significant differences in axillary/loco-regional relapse, distant metastases, disease-free interval or mortality between SN negative and SN positive patients, with a follow-up over 4 years.

Sarcoidosis and Hodgkin's lymphoma represent two distinct diseases with different pathogenic mechanisms, therapeutic interventions, and prognoses. Nevertheless, both diseases can have overlapping presentations, thus blurring the line between successful identification and treatment. A propensity to develop one of these diseases following diagnosis of the other has long been appreciated. Here we review two cases of presumed sarcoidosis that were ultimately diagnosed as Hodgkin's lymphoma. Both patients initially presented with non-specific symptoms and underwent a thorough workup, including histological evaluation demonstrating non-caseating granulomas without evidence of malignancy. Both patients started sarcoid-directed therapies with relapse of symptoms. Repeat imaging and tissue biopsy eventually led to the diagnosis of stage IVB Hodgkin's lymphoma. After the initiation of Hodgkin's-directed therapies, both patients showed marked clinical responses, and entered complete remission.

There have been few naturalistic follow-up studies of dysthymic disorder. This study describes the 5-year course and outcome of dysthymic disorder. The authors conducted a prospective, longitudinal follow-up study of 86 outpatients with early-onset dysthymic disorder and 39 outpatients with episodic major depressive disorder. Follow-ups, conducted 30 and 60 months after entry into the study, rated patients on the Longitudinal Interval Follow-Up Evaluation and the Modified Hamilton Rating Scale for Depression. The estimated 5-year recovery rate from dysthymic disorder was 52.9%. Among patients who recovered, the estimated risk of relapse was 45.2% during a mean of 23 months of observation. Patients with dysthymic disorder spent approximately 70% of the follow-up period meeting the full criteria for a mood disorder. During the course of the follow-up the patients with dysthymic disorder exhibited significantly greater levels of symptoms and lower functioning and were significantly more likely to attempt suicide and to be hospitalized than were patients with episodic major depressive disorder. Finally, among patients with dysthymic disorder who had never experienced a major depressive episode before entry into the study, the estimated risk of having a first lifetime major depressive episode was 76.9%. Dysthymic disorder is a chronic condition with a protracted course and a high risk of relapse. In addition, almost all patients with dysthymic disorder eventually develop superimposed major depressive episodes. Although patients with dysthymic disorder tend to show mild to moderate symptoms, from a longitudinal perspective, the condition is severe.

MS relapses are unpredictable and can be concerning to patients and their caregivers. To assess the direct and indirect cost burden associated with relapses of different severities in MS patients and with MS relapse frequency on spouse caregivers. Using a U.S. insurance claims and employee disability database (1999-2011), we studied adult MS patients (ICD-9-CM: 340.x) and their spouse caregivers. A previously published algorithm to identify relapses was used to stratify: (1) MS patients into cohorts of no, low/moderate, and high severity relapse based on the most severe relapse within one year of follow-up (if any); (2) caregivers into cohorts of no, less, and more frequent relapses based on the overall frequency of relapses of their spouse. Adjusted cost differences and 95% confidence intervals evaluating the yearly incremental costs at 12 months of follow-up (MS patients) and overall (caregivers) associated with relapses are reported. Among the 9421 MS patients (N: no relapse=7686; low/moderate severity relapse=1220; high severity relapse=515) identified, both relapse cohorts incurred significantly higher annual incremental direct costs than the no relapse cohort (low/moderate severity=$8269 [6565-10,115]; high severity=$24,180 [20,263-28,482]) and indirect costs (low/moderate severity=$1429 [759-2147]; high severity=$2714 [1468-4035]). More frequent relapses versus no relapse also translated into a significantly greater cost burden for caregivers (direct+indirect=$1725 [376-2885]) but less frequent relapses did not. Relapse severity was significantly and increasingly associated with greater direct and indirect costs in MS patients. More frequent relapses also translated into a significant cost burden in spouse caregivers. Copyright © 2013 Elsevier B.V. All rights reserved.

The role of neratinib in HER2-driven breast cancer.

Cherian, Mathew A; Ma, Cynthia X

2017-06-30

Up to 25% of patients with early-stage HER2+ breast cancer relapse despite adjuvant trastuzumab-based regimens and virtually all patients with metastatic disease eventually die from resistance to existing treatment options. In addition, recent studies indicate that activating HER2 mutations without gene amplification could drive tumor growth in a subset of HER2-ve breast cancer that is not currently eligible for HER2-targeted agents. Neratinib is an irreversible HER kinase inhibitor with activity as extended adjuvant therapy following standard trastuzumab-based adjuvant treatment in a Phase III trial. Phase II trials of neratinib demonstrate promising activity in combination with cytotoxic agents in trastuzumab resistant metastatic HER2+ breast cancer, and either as monotherapy or in combination with fulvestrant for HER2-mutated breast cancers. We anticipate a potential role for neratinib in the therapy of these patient populations.

Allergic airborne contact dermatitis from essential oils used in aromatherapy.

Contact allergy to various essential oils used in aromatherapy was demonstrated on patch testing in a 53-year-old patient suffering from relapsing eczema resistant to therapy on various uncovered parts of the skin, in particular the scalp, neck and hands. Sensitization was due to previous exposure to lavender, jasmine and rosewood. Laurel, eucalyptus and pomerance also produced positive tests, although there was no hint of previous exposure. A diagnosis of allergic airborne contact dermatitis was thus established. On topical and systemic glucocorticoid treatment (peroral methylprednisolone at an initial dose of 60 mg/day) the skin lesions eventually resolved. Due to persistence of the volatile essential oils in the patient's home after a year-long use of aroma lamps, complete renewal of the interior of the patient's flat was considered essential. Due to changing self-medication habits, with increasing orientation to 'natural' modes of treatment, increasing numbers of such sensitizations might be on the horizon.

Applying current diagnostic methods, overt CNS involvement is a rare event in childhood acute lymphoblastic leukemia (ALL). In contrast, CNS-directed therapy is essential for all patients with ALL because without it, the majority of patients eventually will experience relapse. To approach this discrepancy and to explore potential distinct biologic properties of leukemic cells that migrate into the CNS, we compared gene expression profiles of childhood ALL patients with initial CNS involvement with the profiles of CNS-negative patients. We evaluated leukemic gene expression profiles from the bone marrow of 17 CNS-positive patients and 26 CNS-negative patients who were frequency matched for risk factors associated with CNS involvement. Results were confirmed by real-time quantitative polymerase chain reaction analysis and validated using independent patient samples. Interleukin-15 (IL-15) expression was consistently upregulated in leukemic cells of CNS-positive patients compared with CNS-negative patients. In multivariate analysis, IL-15 expression levels greater than the median were associated with CNS involvement compared with expression equal to or less than the median (odds ratio [OR] = 10.70; 95% CI, 2.95 to 38.81). Diagnostic likelihood ratios for CNS positivity were 0.09 (95% CI, 0.01 to 0.65) for the first and 6.93 (95% CI, 2.55 to 18.83) for the fourth IL-15 expression quartiles. In patients who were CNS negative at diagnosis, IL-15 levels greater than the median were associated with subsequent CNS relapse compared with expression equal to or less than the median (OR = 13.80; 95% CI, 3.38 to 56.31). Quantification of leukemic IL-15 expression at diagnosis predicts CNS status and could be a new tool to further tailor CNS-directed therapy in childhood ALL.

Many patients with acute myeloid leukemia (AML) will eventually develop refractory or relapsed disease. In the absence of standard therapy for this population, there is currently an urgent unmet need for novel therapeutic agents. Targeted therapy with small molecule inhibitors (SMIs) represents a new therapeutic intervention that has been successful for the treatment of multiple tumors (e.g., gastrointestinal stromal tumors, chronic myelogenous leukemia). Hence, there has been great interest in generating selective small molecule inhibitors targeting critical pathways of proliferation and survival in AML. This review highlights a selective group of intriguing therapeutic agents and their presumed targets in both preclinical models and in early human clinical trials. PMID:25025370

Cytomegalovirus (CMV) retinitis is typically diagnosed in patient with AIDS and those who underwent allogeneic hematopoietic cell transplant. However, it may develop in patients with acute lymphoblastic leukemia (ALL) who have not undergone hematopoietic cell transplantation. To increase awareness of CMV retinitis in this group, we describe 3 patients ages 3, 9, and 12, with ALL who developed CMV retinitis. The diagnosis of CMV retinitis was made on the basis of ophthalmological findings suggesting typical retinal lesions. In 2 cases, CMV DNAemia was present, while in 1 patient CMV DNA was detected only in vitreous fluid using the PCR technique. All cases were treated with intravenous ganciclovir for 2 or 3 weeks as induction therapy, followed by oral valganciclovir prophylaxis. Initially, active retinitis lesions resolved in all cases; however, in 1 patient CMV retinitis relapsed 3 times during follow-up. In this case, by using foscarnet therapy, satisfactory responses were achieved and the progression of CMV retinitis lesions stopped and eventually regressed.

Objective: Independent review boards can provide an objective appraisal of investigators' decisions and may be useful for determining complex primary outcomes, such as bipolar disorder relapse, in crossnational studies. This article describes the use of an independent, blinded relapse monitoring board to assess the primary outcome (relapse) in an international clinical trial of risperidone long-acting therapy adjunctive to standard-care pharmacotherapy for patients with bipolar disorder. Design: The fully autonomous relapse monitoring board was composed of a chair and two additional members—all psychiatrists and experts in the diagnostic, clinical, and therapeutic management of bipolar disorder. The relapse monitoring board met six times during the study to review patient relapse data and was charged with the responsibility of determining if the events described by investigators qualified as relapses. Additionally, the relapse monitoring board reviewed data for all randomized patients to identify any relapse events not recognized by investigators. Results: Primary efficacy results were similar and significant for investigator- and relapse monitoring board-determined relapses. Ten discrepancies were noted: two of the 42 investigator-determined relapses did not meet the intended clinical relapse threshold as determined by the relapse monitoring board; conversely, the relapse monitoring board confirmed eight relapse events not identified by investigators. The relapse monitoring board had no direct interactions with patients and had to rely on the accuracy of investigator assessments. Also, once an investigator determined a relapse and the patients discontinued the study, less information was available to the relapse monitoring board for relapse assessment. Conclusions: Use of the relapse monitoring board supported the validity of the study by incorporating a level of standardization to mitigate the risk that local practice in different cultures and medical systems at the sites would confound study results.

Smoking cessation is a primary method of reducing excess mortality and morbidity. Unfortunately, the vast majority of cessation attempts end in eventual relapse. Relapse-prevention interventions have shown some success at improving the long-term maintenance of tobacco abstinence among individuals motivated to abstain. However, involuntary tobacco abstinence (e.g., military training, hospitalization, incarceration) presents another opportunity for intervention to prevent relapse. During basic military training (BMT), tobacco use is strictly forbidden in all service branches, but tobacco relapse (and initiation) following BMT is extremely high. This paper reports on the design, intervention development, and baseline characteristics of a randomized controlled trial testing minimal interventions designed to prevent tobacco relapse among United States Air Force (USAF) personnel following BMT. Participants are randomized by squadron to receive either a standard smoking-cessation booklet, a new motivation-based booklet designed specifically for USAF personal, or the latter booklet combined with a brief, face-to-face motivational session. Primary outcomes will be self-reported tobacco use at 12 and 24month follow-up. Given that the Department of Defense is the world's largest employer, the potential of leveraging involuntary tobacco abstinence during BMT into extended abstinence has substantial public health significance.

2015-05-01

Purpose: To determine, in the setting of advanced-stage of Hodgkin lymphoma (HL), whether relapses occur in the irradiated planning target volume and whether the definition of local radiation therapy (RT) used by the German Hodgkin Study Group (GHSG) is adequate, because there is no harmonization of field and volume definitions among the large cooperative groups in the treatment of advanced-stage HL. Methods and Materials: All patients with residual disease of ≥2.5 cm after multiagent chemotherapy (CTX) were evaluated using additional positron emission tomography (PET), and those with a PET-positive result were irradiated with 30 Gy to the site of residual disease. We re-evaluatedmore » all sites of disease before and after CTX, as well as the PET-positive residual tumor that was treated in all relapsed patients. Documentation of radiation therapy (RT), treatment planning procedures, and portal images were carefully analyzed and compared with the centrally recommended RT prescription. The irradiated sites were compared with sites of relapse using follow-up computed tomography scans. Results: A total of 2126 patients were enrolled, and 225 patients (11%) received RT. Radiation therapy documents of 152 irradiated patients (68%) were analyzed, with 28 irradiated patients (11%) relapsing subsequently. Eleven patients (39%) had an in-field relapse, 7 patients (25%) relapsed outside the irradiated volume, and an additional 10 patients (36%) showed mixed in- and out-field relapses. Of 123 patients, 20 (16%) with adequately performed RT relapsed, compared with 7 of 29 patients (24%) with inadequate RT. Conclusions: The frequency and pattern of relapses suggest that local RT to PET-positive residual disease is sufficient for patients in advanced-stage HL. Insufficient safety margins of local RT may contribute to in-field relapses.« less

Thyroid nodules are frequent findings, especially when sensitive imaging methods are used. Although thyroid cancer is relatively rare, its incidence is increasing, particularly in terms of small tumors, which have an uncertain clinical relevance. Most patients with differentiated thyroid cancer exhibit satisfactory clinical outcomes when treatment is appropriate, and their mortality rate is similar to that of the overall population. However, relapse occurs in a considerable fraction of these patients, and some patients stop responding to conventional treatment and eventually die from their disease. Therefore, the challenge is how to identify the individuals who require more aggressive disease management while sparing the majority of patients from unnecessary treatments and procedures. We have updated the Brazilian Consensus that was published in 2007, emphasizing the diagnostic and therapeutic advances that the participants, representing several Brazilian university centers, consider most relevant in clinical practice. The formulation of the present guidelines was based on the participants' experience and a review of the relevant literature.

Alectinib: a selective, next-generation ALK inhibitor for treatment of ALK-rearranged non-small-cell lung cancer.

2015-06-01

Crizotinib was the first clinically available anaplastic lymphoma kinase (ALK) inhibitor, showing remarkable activity against ALK-rearranged non-small-cell lung cancer (NSCLC). Despite initial responses, acquired resistance to crizotinib inevitably develops, with the brain being a common site of relapse. Alectinib is a highly selective, next-generation ALK inhibitor with potent inhibitory activity also against ALK mutations conferring resistance to crizotinib, including the gatekeeper L1196M substitution. In a Phase I/II study from Japan, alectinib was found to be highly active and safe in crizotinib-naïve, ALK-rearranged NSCLC patients. Alectinib also demonstrated promising antitumor activity in crizotinib-resistant patients, including those with CNS metastases. Based on these data, the drug received Breakthrough Therapy Designation by the US FDA and has been recently approved in Japan for the treatment of ALK-positive, advanced NSCLC patients. However, patients may eventually develop resistance to alectinib, highlighting the need for novel therapeutic strategies to further improve the management of ALK-rearranged NSCLC.

Rituximab is effective against complicated childhood steroid-dependent nephrotic syndrome (SDNS). Peripheral blood B-lymphocyte (B-cell) depletion is strongly correlated with persistent remission, relapse rarely occurring during B-cell depletion; however, we have encountered several such patients. We retrospectively analyzed the characteristics and clinical course of 82 patients with SDNS treated with rituximab from January 2007 to December 2012 in our institution. Six of 82 patients (7.3%) had relapses during B-cell depletion after receiving rituximab (relapsed group). The remaining 76 patients did not have relapses during B-cell depletion (non-relapsed group). The median time to initial relapse during B-cell depletion was 85 days after receiving rituximab, which is significantly shorter than in the non-relapsed group (410 days, p = 0.0003). The median annual numbers of relapses after receiving rituximab were 2.5 and 0.9 in the relapsed and non-relapsed groups, respectively (p < 0.0001). Five patients in the relapsed group also had a total of 10 relapses after B-cell recovery; their median time from B-cell recovery to initial relapse was significantly shorter than in the non-relapsed group (31 vs. 161 days, p = 0.014). Number of relapses before rituximab, history of steroid resistance, onset age, previous treatment, time to ceasing steroids after rituximab, and duration of B-cell depletion did not differ between the two groups. Relapse during B-cell depletion after receiving rituximab suggests that various pathophysiological mechanisms play a part in childhood nephrotic syndrome.

It is unknown if vaccines cause non-specific immune activation in patients with neuromyelitis optica spectrum disorder and no consensus on the use of vaccines exists for this population. We investigated the temporal association of vaccinations with relapses in patients with neuromyelitis optica spectrum disorder. This is a multi-center retrospective analysis of patients with neuromyelitis optica spectrum disorder for whom immunization history and clinical records from disease onset were available. Ninety patients who met 2015 diagnostic criteria received a total of 211 vaccinations and experienced 340 relapses over a median disease course of 6.6 years. The likelihood of a relapse occurring within 30, 60, and 90 days of a vaccine was compared to the likelihood of a relapse occurring within each time point of a randomly generated date. We also compared the relapse rate between patients who received any vaccination(s) after disease onset to those who did not. We identified seven patients with neuromyelitis optica spectrum disorder who relapsed within 30 days of a vaccination, six between 31 and 60 days, and four who relapsed between 61 and 90 days. The rate of vaccine-associated relapses within 30, 60, and 90 days was significantly higher than the likelihood of a relapse spontaneously occurring within each of the given time frames (p = 0.034, 0.01, 0.016, respectively) among patients who were not on preventive immunotherapy only. Among those who were on immunotherapy to prevent relapses, there was no significant association of relapse with vaccines. Additionally, among patients on immunotherapy, the annualized relapse rate of those who received routine vaccinations was significantly lower than in unvaccinated patients. The evidence suggests that there may be a risk of vaccination-associated relapses among untreated neuromyelitis optica spectrum disorder patients, however immunosuppressive therapy at time of vaccine may abort the risk; this suggests that the patients who are treated with preventive immune suppression and receive routine vaccinations for common infections may fare better. Further prospective studies are necessary to verify these findings. Copyright © 2018 Elsevier B.V. All rights reserved.

Purpose: To describe the MRI appearances of squamous cell carcinoma of the anal canal before and after chemoradiation and to assess whether MRI features predict for clinical outcome. Methods and Materials: Thirty-five patients (15 male, 20 female; mean age 60.8 years) with histologically proven squamous cell cancer of the anal canal underwent MRI before and 6-8 weeks after definitive chemoradiation. Images were reviewed retrospectively by two radiologists in consensus blinded to clinical outcome: tumor size, signal intensity, extent, and TNM stage were recorded. Following treatment, patients were defined as responders by T and N downstaging and Response Evaluation Criteria inmore » Solid Tumors (RECIST). Final clinical outcome was determined by imaging and case note review: patients were divided into (1) disease-free and (2) with relapse and compared using appropriate univariate methods to identify imaging predictors; statistical significance was at 5%. Results: The majority of tumors were {<=}T2 (23/35; 65.7%) and N0 (21/35; 60%), mean size 3.75cm, and hyperintense (++ to +++, 24/35 patients; 68%). Following chemoradiation, there was a size reduction in all cases (mean 73.3%) and a reduction in signal intensity in 26/35 patients (74.2%). The majority of patients were classified as responders (26/35 (74.2%) patients by T and N downstaging; and 30/35 (85.7%) patients by RECIST). At a median follow-up of 33.5 months, 25 patients (71.4%) remained disease-free; 10 patients (28.6%) had locoregional or metastatic disease. Univariate analysis showed that no individual MRI features were predictive of eventual outcome. Conclusion: Early assessment of response by MRI at 6-8 weeks is unhelpful in predicting future clinical outcome.« less

Kim, Ji Hyun; Stein, Anthony; Tsai, Nicole

Purpose: Approximately 5% to 20% of patients who undergo total body irradiation (TBI) in preparation for hematopoietic cell transplantation (HCT) can develop extramedullary (EM) relapse. Whereas total marrow and lymphoid irradiation (TMLI) provides a more conformally targeted radiation therapy for patients, organ sparing has the potential to place the patient at a higher risk for EM relapse than TBI. This study evaluated EM relapse in patients treated with TMLI at our institution. Methods and Materials: Patients eligible for analysis had been enrolled in 1 of 3 prospective TMLI trials between 2006 and 2012. The TMLI targeted bones, major lymph nodemore » chains, liver, spleen, testes, and brain, using image-guided tomotherapy with total dose ranging from 12 to 15 Gy. Results: A total of 101 patients with a median age of 47 years were studied. The median follow-up was 12.8 months. Incidence of EM relapse and bone marrow (BM) relapse were 12.9% and 25.7%, respectively. Of the 13 patients who had EM relapse, 4 also had BM relapse, and 7 had EM disease prior to HCT. There were a total of 19 EM relapse sites as the site of initial recurrence: 11 soft tissue, 6 lymph node, 2 skin. Nine of these sites were within the target region and received ≥12 Gy. Ten initial EM relapse sites were outside of the target region: 5 sites received 10.1 to 11.4 Gy while 5 sites received <10 Gy. Pretransplantation EM was the only significant predictor of subsequent EM relapse. The cumulative incidence of EM relapse was 4% at 1 year and 11.4% at 2 years. Conclusions: EM relapse incidence was as frequent in regions receiving ≥10 Gy as those receiving <10 Gy. EM relapse rates following TMLI that included HCT regimens were comparable to published results with regimens including TBI and suggest that TMLI is not associated with an increased EM relapse risk.« less

Purpose: External beam radiation therapy to initial sites of disease may influence relapse patterns in high-risk neuroblastoma. However, the effect of systemic irradiation by use of total body irradiation (TBI) on anatomic patterns of relapse has not previously been investigated. Methods and Materials: We retrospectively analyzed patients receiving definitive treatment of high-risk neuroblastoma with subsequent relapse in bony metastatic sites, with a date of relapse between January 1, 1997, and December 31, 2012. Anatomic sites of disease, defined by metaiodobenzylguanidine (MIBG) avidity, were compared at diagnosis and at first relapse. The Fisher exact test was performed to compare relapse inmore » initially involved sites between patients treated with and without TBI. Results: Seventy-four patients with a median age at diagnosis of 3.5 years (range, 0.3-15.3 years) had relapse in 227 sites of MIBG-avid metastatic disease, with a median time to relapse of 1.8 years. Of the 227 sites of first relapse, 154 sites (68%) were involved at diagnosis. When we compared relapse patterns in patients treated with and without TBI, 12 of 23 patients (52%) treated with TBI had relapse in ≥1 previously MIBG-avid site of disease whereas 40 of 51 patients (78%) treated without TBI had relapse in ≥1 previously MIBG-avid site of disease (P=.03). Conclusions: Patients treated with systemic irradiation in the form of TBI were significantly less likely to have relapse in prior sites of disease. These findings support further investigation into the role of radiopharmaceutical therapies in curative multimodality therapy.« less

Cell-mediated immunity (CMI) plays a critical role in the control of brucellosis. Regulatory T cells (Tregs) have a functional character in modulating the balance between host immune response and tolerance, which can eventually lead to chronic infection or relapse. The aim of this study was to assess the alteration of Tregs in cases of brucellosis before and after treatment. Thirty cases of acute brucellosis with the mean age of 41.03±15.15 years (case group) and 30 healthy persons with the mean age of 40.63±13.95 years (control group) were selected and assessed. Peripheral blood mononuclear cells (PBMCs) were isolated from peripheral blood of all individuals. We analyzed the alteration of Treg cell count using flow cytometry for CD4, CD25, and FoxP3 markers. The level of CD4+ CD25+ FoxP3+ Treg cells was increased in active patients compared with controls (2.5±0.99% vs 1.6±0.84%, p= 0.0004), but it had declined in the treated cases (1.83±0.73%, p=0.02). The level of Tregs was elevated in three relapsed cases. The frequency of Tregs and Treg/Teff (effector T cell) ratio was correlated with inverse serum agglutination test (SAT) and, 2-mercaptoethanol (2-ME) titers as markers of treatment in brucellosis. Based on our findings, we suggest that regulatory cells, such as CD4+ CD25+ FoxP3+ Treg cells, may contribute to the development of infection processes involving immune responses in brucellosis, and evaluation of regulatory T-cell levels may be a potential diagnostic strategy for the treatment outcome in chronic and relapsed cases of brucellosis.

Severe nelarabine neurotoxicity in a patient who received concurrent intrathecal (IT) chemotherapy is reported. A 37-year-old Caucasian woman with a history of T-cell lymphoblastic lymphoma was admitted for relapsed disease. She was originally treated with induction chemotherapy followed by an autologous transplant. She developed relapsed disease 10 months later with leukemic involvement. She was re-induced with nelarabine 1500 mg/m(2) on days 1, 3, and 5 with 1 dose of IT cytarabine 100 mg on day 2 as central nervous system (CNS) prophylaxis. At the time of treatment, she was on continuous renal replacement therapy due to sequelae of tumor lysis syndrome (TLS). She tolerated therapy well, entered a complete remission, and recovered her renal function. She received a second cycle of nelarabine without additional IT prophylaxis one month later. A week after this second cycle, she noted numbness in her lower extremities. Predominantly sensory, though also motor and autonomic, peripheral neuropathy started in her feet, ascended proximally to the mid-thoracic region, and eventually included her distal upper extremities. A magnetic resonance imaging (MRI) of her spine demonstrated changes from C2 to C6 consistent with subacute combined degeneration. Nelarabine was felt to be the cause of her symptoms. Her neuropathy stabilized and showed slight improvement and ultimately received an unrelated, reduced-intensity allogeneic transplant while in complete remission, but relapsed disease 10 weeks later. She is currently being treated with best supportive care. To our knowledge, this is the first published case report of severe neurotoxicity caused by nelarabine in a patient who received concurrent IT chemotherapy. © The Author(s) 2014.

Acute myeloid leukemia (AML) is the most frequent type of acute leukemia in adults. Despite recent advances in the characterization of pathogenesis of AML, the cure rates are under 40%, being leukemia relapse the most common cause of treatment failure. Leukaemia relapse occurs due to clonal evolution or clonal escape. In this study, we aimed to analyze the clinical and biological factors influencing outcomes in patients with AML relapse. We included a total of 75 AML patients who experienced leukaemia relapse after achieving complete remission. We performed complete immunophenotyping and conventional karyotyping in bone marrow aspirates obtained at diagnosis and at leukemia relapse. Overall survival (OS) of the series was 3.7%±2.3, leukaemia progression being the most common cause of death. Patients relapsing before 12 months and those with adverse cytogenetic-molecular risk had statistically significant worse outcomes. A percentage of 52.5 of patients showed phenotypic changes and 50% cytogenetic changes at relapse. We did not find significant clinical factors predicting clonal evolution. The presence of clonal evolution at relapse did not have a significant impact on outcome. Patients with relapsed AML have a dismal prognosis, especially those with early relapse and adverse cytogenetic-molecular risk. Clonal evolution with phenotypic and cytogenetic changes occurred in half of the patients without predictive clinical factors or impact on outcome. Copyright © 2016 Elsevier España, S.L.U.

Laurberg, Peter; Krejbjerg, Anne; Andersen, Stine Linding

In most patients with hyperthyroidism caused by Graves' disease, antithyroid drug (ATD) therapy is followed by a gradual amelioration of the autoimmune abnormality, but about half of the patients will experience relapse of hyperthyroidism when the ATDs are withdrawn after a standard 1 to 2 years of therapy. This is a major drawback of ATD therapy, and a major concern to patients. We review current knowledge on how to predict and possibly reduce the risk of such relapse. Several patient and disease characteristics, as well as environmental factors and duration of ATD therapy, may influence the risk of relapse after ATD withdrawal. Depending on the presence of such factors, the risk of relapse after ATD withdrawal may vary from around 10 to 90%. Risk factors for relapse should be taken into account when choosing between therapeutic modalities in a patient with newly diagnosed disease, and also when discussing duration of ATD therapy. Prolonged low-dose ATD therapy may be feasible in patients with high risk of relapse, such as children and patients with active Graves' orbitopathy, and in patients with previous relapse who prefer such therapy rather than surgery or radioiodine.

For patients with relapsed or refractory diffuse large B-cell lymphoma (DLBCL), autologous hematopoietic cell transplantation (auto-HCT) is commonly used. After auto-HCT, DLBCL patients are often monitored with surveillance imaging. However, there is little evidence to support this practice. We performed a multicenter retrospective study of DLBCL patients who underwent auto-HCT (n = 160), who experienced complete remission after transplantation, and who then underwent surveillance imaging. Of these, only 45 patients experienced relapse after day +100 after auto-HCT, with relapse detected by routine imaging in 32 (71%) and relapse detected clinically in 13 (29%). Baseline patient characteristics were similar between the 2 groups. Comparing the radiographic and clinically detected relapse groups, the median time from diagnosis to auto-HCT (389 days vs. 621 days, P = .06) and the median follow-up after auto-HCT (2464 days vs. 1593 days P = .60) were similar. The median time to relapse after auto-HCT was 191 days in radiographically detected relapses compared to 492 days in clinically detected relapses (P = .35), and median postrelapse survival was 359 days in such patients compared to 123 days in patients with clinically detected relapse (P = .36). However, the median posttransplantation overall survival was not significantly different for patients with relapse detected by routine imaging versus relapse detected clinically (643 vs. 586 days, P = .68). A majority (71%) of DLBCL relapses after auto-HCT are detected by routine surveillance imaging. Overall, there appears to be limited utility for routine imaging after auto-HCT except in select cases where earlier detection and salvage therapy with allogeneic HCT is a potential option.

Background Although organizing pneumonia (OP) responds well to corticosteroid therapy, relapse is common during dose reduction or follow-up. Predictors of relapse in OP patients remain to be established. The aim of the present study was to identify factors related to relapse in OP patients. Methods This study was retrospectively performed in a tertiary referral center. Of 66 OP patients who were improved with or without treatment, 20 (30%) experienced relapse. The clinical and radiologic parameters in the relapse patient group (n=20) were compared to that in the non-relapse group (n=46). Results Multivariate analysis demonstrated that percent predicted forced vital capacity (FVC), PaO2/FiO2, and serum protein level were significant predictors of relapse in OP patients (odds ratio [OR], 0.82; 95% confidence interval [CI], 0.70-0.97; p=0.018; OR, 1.02; 95% CI, 1.00-1.04; p=0.042; and OR, 0.06; 95% CI, 0.01-0.87; p=0.039, respectively). Conclusion This study shows that FVC, PaO2/FiO2 and serum protein level at presentation can significantly predict relapse in OP patients. PMID:26175771

Cumulative 10-yr relapse rates in ulcerative colitis (UC) of 70% to almost 100% have been reported in regional studies. The aim of this study was to determine the relapse rate in UC in a European population-based cohort 10 yr after diagnosis and to identify factors that may influence the risk of relapse. From 1991 to 1993, 771 patients with UC from seven European countries and Israel were prospectively included in a population-based inception cohort and followed for 10 yr. A relapse was defined as an increase in UC-related symptoms leading to changes in medical treatment or surgery. The cumulative relapse rate, time to first relapse, and number of relapses in the follow-up period were recorded and possible causative factors were investigated. The cumulative relapse rate of patients with at least one relapse was 0.67 (95% CI 0.63-0.71). The time to first relapse showed a greater hazard ratio (HR) (1.2, CI 1.0-1.5) for women and for patients with a high level of education (1.4, CI 1.1-1.8). The number of relapses decreased with age, and current smokers had a lower relapse rate (0.8, CI 0.6-0.9) than nonsmokers. The relapse rate in women was 1.2 (CI 1.1-1.3) times higher than in men. An inverse relation was found between the time to the first relapse and the total number of relapses. In 67% of patients, there was at least one relapse. Smoking status, level of education, and possibly female gender were found to influence the risk of relapse.

Autoimmune hepatitis (AIH) is characterized by progressive inflammation and necrosis of hepatocytes and eventually leads to a variety of phenotypes, including acute liver dysfunction, chronic progressive liver disease, and fulminant hepatic failure. Although the precise mechanisms of AIH are unknown, environmental factors may trigger disease onset in genetically predisposed individuals. Patients with the recently established entity of AIH with acute presentation often display atypical clinical features that mimic those of acute hepatitis forms even though AIH is categorized as a chronic liver disease. The aim of this study was to identify the precise clinical features of AIH with acute presentation. Eighty-six AIH patients with acute presentation were retrospectively enrolled from facilities across Japan and analyzed for clinical features, histopathological findings, and disease outcomes. Seventy-five patients were female and 11 were male. Patient age ranged from adolescent to over 80 years old, with a median age of 55 years. Median alanine transaminase (ALT) was 776 U/L and median immunoglobulin G (IgG) was 1671 mg/dL. There were no significant differences between genders in terms of ALT (P = 0.27) or IgG (P = 0.51). The number of patients without and with histopathological fibrosis was 29 and 57, respectively. The patients with fibrosis were significantly older than those without (P = 0.015), but no other differences in clinical or histopathological findings were observed. Moreover, antinuclear antibody (ANA)-positive (defined as × 40, N = 63) and -negative (N = 23) patients showed no significant differences in clinical or histopathological findings or disease outcomes. Twenty-five patients experienced disease relapse and two patients died during the study period. ALP ≥ 500 U/L [odds ratio (OR) 3.20; 95% confidence interval (CI) 1.12-9.10; P < 0.030] and GGT ≥ 200 U/L (OR 2.98; 95% CI 1.01-8.77; P = 0.047) were identified as independent risk factors of disease relapse. AIH with acute presentation is a newly recognized disease entity for which diagnostic hallmarks, such as ALT, fibrosis, and ANA, are needed. Further investigation is also required on the mechanisms of this disorder. Clinicians should be mindful of disease relapse during patient care.

The Infection Returns: A Case of Pulmonary Sporotrichosis Relapse after Chemotherapy

PubMed Central

2018-01-01

Background Pulmonary sporotrichosis is a rare disease caused by a dimorphic fungus, Sporothrix schenckii. It is rarely found in association with malignancy. We present a case of pulmonary sporotrichosis recurrence after chemotherapy. Case Presentation A 44-year-old man, treated for pulmonary sporotrichosis in the past, presented with dysphagia and was found to have squamous cell carcinoma of the esophagus. After undergoing chemotherapy, extensive cavitary lesions were observed on thoracic computed tomography scan. A bronchoalveolar lavage revealed the presence of Sporothrix schenckii sensu lato. Despite treatment with itraconazole, he eventually required a left pneumonectomy for progressive destructive cavitary lesions involving the left lung. Conclusion This case highlights the importance of considering past fungal infections, albeit cured, in patients initiating immunosuppressive therapy. PMID:29559998

Relapse is a common measure of disease activity in relapsing-remitting multiple sclerosis (MS). The objective of this study was to test the content validity of an operational algorithm for detecting relapse in claims data. A claims-based relapse detection algorithm was tested by comparing its detection rate over a 1-year period with relapses identified based on medical chart review. According to the algorithm, MS patients in a US healthcare claims database who had either (1) a primary claim for MS during hospitalization or (2) a corticosteroid claim following a MS-related outpatient visit were designated as having a relapse. Patient charts were examined for explicit indication of relapse or care suggestive of relapse. Positive and negative predictive values were calculated. Medical charts were reviewed for 300 MS patients, half of whom had a relapse according to the algorithm. The claims-based criteria correctly classified 67.3% of patients with relapses (positive predictive value) and 70.0% of patients without relapses (negative predictive value; kappa 0.373: p < 0.001). Alternative algorithms did not improve on the predictive value of the operational algorithm. Limitations of the algorithm include lack of differentiation between relapsing-remitting MS and other types, and that it does not incorporate measures of function and disability. The claims-based algorithm appeared to successfully detect moderate-to-severe MS relapse. This validated definition can be applied to future claims-based MS studies.

Objective Stress is thought to be one of the triggers of relapses in patients with inflammatory bowel disease (IBD). We examined the rate of relapse in IBD patients before and after the Great East Japan Earthquake. Design A retrospective cohort study. Settings 13 hospitals in Japan. Participants 546 ulcerative colitis (UC) and 357 Crohn's disease (CD) patients who received outpatient and inpatient care at 13 hospitals located in the area that were seriously damaged by the earthquake. Data on patient's clinical characteristics, disease activity and deleterious effects of the earthquake were obtained from questionnaires and hospital records. Primary outcome We evaluated the relapse rate (from inactive to active) across two consecutive months before and two consecutive months after the earthquake. In this study, we defined ‘active’ as conditions with a partial Mayo score=2 or more (UC) or a Harvey-Bradshaw index=6 or more (CD). Results Among the UC patients, disease was active in 167 patients and inactive in 379 patients before the earthquake. After the earthquake, the activity scores increased significantly (p<0.0001). A total of 86 patients relapsed (relapse rate=15.8%). The relapse rate was about twice that of the corresponding period in the previous year. Among the CD patients, 86 patients had active disease and 271 had inactive disease before the earthquake. After the earthquake, the activity indices changed little. A total of 25 patients experienced a relapse (relapse rate=7%). The relapse rate did not differ from that of the corresponding period in the previous year. Multivariate analyses revealed that UC, changes in dietary oral intake and anxiety about family finances were associated with the relapse. Conclusions Life-event stress induced by the Great East Japan Earthquake was associated with relapse in UC but not CD. PMID:23396562

The radiologic features and patterns of primary central nervous system lymphoma (PCNSL) at initial presentation are well described. High response rates can be achieved with first-line high-dose methotrexate (HD-MTX) based regimens, yet many relapse within 2 years of diagnosis. We describe the pattern of relapse and review the potential mechanisms involved in relapse. We identified 78 consecutive patients who attained complete radiographic response (CR) during or after first-line treatment for newly diagnosed PCNSL (CD20+, diffuse large B cell type). Patients were treated with HD-MTX based regimen in conjunction with blood-brain barrier disruption (HD-MTX/BBBD); 44 subsequently relapsed. Images and medical records of these 44 consecutive patients were retrospectively reviewed. The anatomical location of enhancing lesions at initial diagnosis and at the time of relapse were identified and compared. 37/44 patients fulfilled inclusion criteria and had new measureable enhancing lesions at relapse; the pattern and location of relapse of these 37 patients were identified. At relapse, the new enhancement was at a spatially distinct site in 30 of 37 patients. Local relapse was found only in seven patients. Unlike gliomas, the majority of PCNSL had radiographic relapse at spatially distinct anatomical locations within the brain behind a previously intact neurovascular unit (NVU), and in few cases outside, the central nervous system (CNS). This may suggest either (1) reactivation of occult reservoirs behind an intact NVU in the CNS (or ocular) or (2) seeding from bone marrow or other extra CNS sites. Recognizing patterns of relapse is key for early detection and may provide insight into potential mechanisms of relapse as well as help develop strategies to extend duration of complete response.

To describe the results in terms of audiometric relapse-free survival and relapse rate in immunomediated hearing loss patients treated exclusively with corticosteroids. Retrospective study of patients with audiometric relapses, monitored from 1995 to 2014, in two centres of the Community of Madrid. We evaluated 31 patients with a mean age of 48.52 years (14.67 SD), of which 61.3% were women. Most hearing loss was fluctuating (48.4%). Only 16.1% of patients had systemic autoimmune disease. There is a moderate positive correlation between the sex variable and the systemic involvement variable (Spearman's correlation coefficient=0.356): specifically, between being female and systemic disease. The relative incidence rate of relapse in the first year was 2.01 relapses/year with a 95% CI (1.32 to 2.92). The mean survival time of the event (audiometric relapse) was 5.25 months (SD 0.756). With multivariate analysis, the only variable that achieved statistical significance was age, with a hazard ratio of 1.032 (95% CI; 1.001-1.063, P=.043). Immune-mediated disease of the inner ear is a chronic disease with relapses. Half of the patients with immunomediated hearing loss treated exclusively with corticosteroids relapse before 6 months of follow-up. In addition, if a patient has not relapsed, they are more likely to relapse as each year passes. Analysis of the of audiometric relapse- free survival will enable the effect of future treatments to be compared and their capacity to reduce the rhythm of relapses.

Acute B lymphoblastic leukemia (B-ALL) is one of the most common types of childhood cancer worldwide and chemotherapy is the main treatment approach. Despite good response rates to chemotherapy regiments, many patients eventually relapse and minimal residual disease (MRD) is the leading risk factor for relapse. The evolution of leukemic clones during disease development and treatment may have clinical significance. In this study, we performed immunoglobulin heavy chain ( IGH ) repertoire high throughput sequencing (HTS) on the diagnostic and post-treatment samples of 51 pediatric B-ALL patients. We identified leukemic IGH clones in 92.2% of the diagnostic samples and nearly half of the patients were polyclonal. About one-third of the leukemic clones have correct open reading frame in the complementarity determining region 3 (CDR3) of IGH , which demonstrates that the leukemic B cells were in the early developmental stage. We also demonstrated the higher sensitivity of HTS in MRD detection and investigated the clinical value of using peripheral blood in MRD detection and monitoring the clonal IGH evolution. In addition, we found leukemic clones were extensively undergoing continuous clonal IGH evolution by variable gene replacement. Dynamic frequency change and newly emerged evolved IGH clones were identified upon the pressure of chemotherapy. In summary, we confirmed the high sensitivity and universal applicability of HTS in MRD detection. We also reported the ubiquitous evolved IGH clones in B-ALL samples and their response to chemotherapy during treatment.

Leptomeningeal metastases (LM) are an increasingly frequent and devastating complication of anaplastic lymphoma kinase (ALK)-rearranged non-small-cell lung cancer (NSCLC). Currently, the optimal management of LM in ALK-positive patients remains poorly understood as these patients have been routinely excluded from clinical trials. We describe four ALK-positive patients with LM who were treated with the next-generation ALK inhibitor alectinib through single-patient, compassionate use protocols at two institutions. All patients had previously been treated with both FDA-approved ALK inhibitors--crizotinib and ceritinib. Patients received alectinib at a starting dose of 600 mg twice daily. Four ALK-positive NSCLC patients with symptomatic leptomeningeal disease were identified. Three of four patients experienced significant clinical and radiographic improvements in LM upon treatment with alectinib. A fourth patient had stable intracranial disease for 4 months before eventual systemic disease progression. Overall, alectinib was well tolerated. One patient required dose reduction due to grade 2 hyperbilirubinemia. Alectinib is active in ALK-rearranged NSCLC patients with LM, including in patients previously treated with crizotinib and ceritinib. Additional prospective studies of alectinib in ALK-positive patients with LM are warranted.

While electroconvulsive therapy (ECT) treatment for depression is highly effective, the high rate of relapse is a critical problem. The current study investigated factors associated with the risk of relapse in mood disorders in patients in which ECT was initially effective. The records of 100 patients with mood disorders (61 unipolar depression, 39 bipolar depression) who received and responded to an acute ECT course were retrospectively reviewed. Associations between clinical variables and relapse after responding to acute ECT were analyzed. The Ethics Committee of NHO Kure Medical Center approved the study protocol. After one year, the percentage of relapse-free patients was 48.7%. There was no significant difference between patients with either unipolar or bipolar depression who were relapse-free (unipolar: 51.1%, bipolar: 45.5%, P=0.603). Valproate maintenance pharmacotherapy in unipolar depression patients was associated with a lower risk of relapse compared to patients without valproate treatment (multivariate analysis, hazard ratio: 0.091; P=0.022). Lithium treatment, reportedly effective for unipolar depression following a course of ECT, tended to lower the risk of relapse (hazard ratio: 0.378; P=0.060). For bipolar depression, no treatment significantly reduced the risk of relapse. The current findings were retrospective and based on a limited sample size. The relapse-free rate was similar between unipolar and bipolar depression. Valproate could have potential for unipolar depression patients as a maintenance therapeutic in preventing relapse after ECT. Copyright © 2016 Elsevier B.V. All rights reserved.

Background Tumor recurrence remains the major clinical complication of meningiomas, the majority of recurrences occurring among WHO grade I/benign tumors. In the present study, we propose a new scoring system for the prognostic stratification of meningioma patients based on analysis of a large series of meningiomas followed for a median of >5 years. Methods Tumor cytogenetics were systematically investigated by interphase fluorescence in situ hybridization in 302 meningioma samples, and the proposed classification was further validated in an independent series of cases (n = 132) analyzed by high-density (500K) single-nucleotide polymorphism (SNP) arrays. Results Overall, we found an adverse impact on patient relapse-free survival (RFS) for males, presence of brain edema, younger patients (<55 years), tumor size >50 mm, tumor localization at intraventricular and anterior cranial base areas, WHO grade II/III meningiomas, and complex karyotypes; the latter 5 variables showed an independent predictive value in multivariate analysis. Based on these parameters, a prognostic score was established for each individual case, and patients were stratified into 4 risk categories with significantly different (P < .001) outcomes. These included a good prognosis group, consisting of approximately 20% of cases, that showed a RFS of 100% ± 0% at 10 years and a very poor-prognosis group with a RFS rate of 0% ± 0% at 10 years. The prognostic impact of the scoring system proposed here was also retained when WHO grade I cases were considered separately (P < .001). Conclusions Based on this risk-stratification classification, different strategies may be adopted for follow-up, and eventually also for treatment, of meningioma patients at different risks for relapse.

Relapse in ANCA-associated vasculitis (AAV) has been studied previously, but there are few studies on renal relapse in particular. Identifying patients at high risk of renal relapse may aid in optimizing clinical management. We investigated which clinical and histological parameters are risk factors for renal relapse in ANCA-associated glomerulonephritis (AAGN). Patients (n = 174) were newly diagnosed and had mild-moderate or severe renal involvement. Data were derived from two trials of the European Vasculitis Society: MEPEX and CYCAZAREM. The Cox regression model was used to identify parameters increasing the instantaneous risk (= rate) of renal relapse (useful for instant clinical decisions). For identifying predictors of renal relapse during follow-up, we used Fine & Gray's regression model. Competing events were end-stage renal failure and death. The cumulative incidence of renal relapse at 5 years was 9.5% (95% CI: 4.8-14.3%). In the Cox model, sclerotic class AAGN increased the instantaneous risk of renal relapse. In Fine & Gray's model, the absence of interstitial infiltrates at diagnosis was predictive for renal relapse. In this study we used two different models to identify possible relationships between clinical and histopathological parameters at time of diagnosis of AAV with the risk of experiencing renal relapse. Sclerotic class AAGN increased the instantaneous risk of renal relapse. This association is most likely due to the high proportion of sclerosed glomeruli reducing the compensatory capacity. The absence of interstitial infiltrates increased the risk of renal relapse which is a warning sign that patients with a relatively benign onset of disease may also be prone to renal relapse. Renal relapses occurring in patients with sclerotic class AAGN and renal relapses occurring in patients without interstitial infiltrates were mutually exclusive, which may indicate that they are essentially different.

Rationale: Almost half of the patients with anti-neutrophil cytoplasmic antibodies (ANCA) associated small vessel vasculitis relapse and their characteristics are still to be defined Objective: We aimed to evaluate the relapse rate and its determinants in a cohort of patients with ANCA associated vasculitis with severe kidney involvement. Methods and results: This is a retrospective study which included 100 patients consecutively admitted in a Nephrology Department with crescentic pauci-immune glomerulonephritis diagnosed by kidney biopsy. ANCAs were assessed by capture ELISA or indirect immunofluorescence (IFI). Patients were followed for a median period of 3.2 [0.1; 5.5] years. The median age was 61.6 years. The clinical condition at presentation was severe (median BVAS 16 and BVAS over 21 in one quarter of patients), mostly because of general, kidney and lung scores. Median creatinine was 5.7 mg/dL and 17% of the patients needed temporary dialysis. Eight patients relapsed (13.8%): one in the lung and seven in the kidney. The median time to relapse was 11.3 [9.2; 19.9] months. None of the investigated parameters allowed for differentiating patients who relapsed from those who did not, except higher hematuria in those who relapsed. Discussion: In our patients with ANCA vasculitis and severe kidney involvement, the relapse rate is low and hematuria but not ANCA specificity or clinical presentation allows the prediction of relapse.

Abstract Background Matrix metalloproteinases are involved in neuroinflammatory processes, which could underlie depression. Serum levels of MMP-9 and MMP-2 in depressed patients are significantly altered following electroconvulsive therapy, but an association between altered matrix metalloproteinases after successful ECT and possible relapse has yet to be investigated. Methods Serum was obtained twice, before and immediately after a course of electroconvulsive therapy, from 38 depressed patients. Serum was also collected, once, from two groups of age- and gender-matched healthy controls, 40 volunteers in each group. Possible associations between levels of matrix metalloproteinases and relapse during a 1-year follow-up period were analyzed. Results Excluding patients who did not respond to electroconvulsive therapy and patients lost to follow-up, data from 28 patients were evaluated. Eighteen of the patients (64.3%) relapsed within 1 year. In the group that did not relapse, serum levels of MMP-9 were significantly decreased after a course of electroconvulsive therapy, but not in the group that relapsed. No association between MMP-2 and relapse was observed. Conclusion The degree of change in serum MMP-9 change could be associated with relapse following electroconvulsive therapy in depressed patients. PMID:29025075

The purpose of this study was to explore the incidence of late relapse in patients with malignant germ cell tumour (MGCT) in a population-based series, with emphasis on the mode of detection, survival, and the relevance of histological findings. The clinical records from a population-based cohort of patients with seminoma (n=1123) or non-seminoma (n=826) were evaluated for late relapses. Twenty-five patients developed a late relapse. The cumulative 10-year incidence rate was 1.3%. All 10 seminoma patients, but only eight of 15 non-seminoma patients relapsed with vital malignant tumour (P=0.02). Teratoma or necrosis was found in seven of nine primarily chemotherapy-treated non-seminoma patients with normal tumour markers at late relapse. Six of nine patients operated with limited retroperitoneal lymph node dissection as part of the primary treatment had relapsed retroperitoneally outside the original operation field. The 10-year cause-specific survival was 68% in all patients, 50% in patients relapsing with vital malignant tumour and 100% in those with teratoma/ necrosis before or after salvage chemotherapy. The 10-year incidence rate of late relapses of 1.3% might reflect the true incidence rate in a population-based cohort of MGCT patients, with cure in at least half of them. PMID:16508636

Allogeneic hematopoietic SCT (allo-SCT) is a promising therapy that may provide long-term durable remission for adult T-cell leukemia-lymphoma (ATL) patients; however, the incidence of relapse associated with ATL remains high. To determine the clinical features of these patients at relapse, we retrospectively analyzed tumor lesions in 30 or 49 patients who relapsed following allo-SCT or chemotherapy (CHT), respectively, at three institutions in Nagasaki prefecture between 1997 and 2011. A multivariate analysis revealed that the development of abnormal lymphocytes in the peripheral blood of patients at relapse was less frequent after allo-SCT than after CHT (P<0.001). Furthermore, relapse with a new lesion only in the absence of the primary lesion was more frequent in allo-SCT (P=0.014). Lesions were more frequently observed in the central nervous systems of patients who relapsed with new lesions only (P=0.005). Thus, the clinical manifestation of relapsed ATL was slightly complex, especially in post-transplant patients. Our results emphasized the need to develop adoptive modalities for early and accurate diagnoses of relapsed ATL.

To describe non-relapse-related emergency consultations of patients with multiple sclerosis (MS): causes, difficulties in the diagnosis, clinical characteristics, and treatments administered. We performed a retrospective study of patients who attended a multiple sclerosis day hospital due to suspected relapse and received an alternative diagnosis, over a 2-year period. Demographic data, clinical characteristics, final diagnosis, and treatments administered were evaluated. Patients who were initially diagnosed with pseudo-relapse and ultimately diagnosed with true relapse were evaluated specifically. As an exploratory analysis, patients who consulted with non-inflammatory causes were compared with a randomly selected cohort of patients with true relapses who attended the centre in the same period. The study included 50 patients (33 were women; mean age 41.4±11.7years). Four patients (8%) were initially diagnosed with pseudo-relapse and later diagnosed as having a true relapse. Fever and vertigo were the main confounding factors. The non-inflammatory causes of emergency consultation were: neurological, 43.5% (20 patients); infectious, 15.2% (7); psychiatric, 10.9% (5); vertigo, 8.6% (4); trauma, 10.9% (5); and miscellaneous, 10.9% (5). MS-related symptoms constituted the most frequent cause of non-inflammatory emergency consultations. Close follow-up of relapse and pseudo-relapse is necessary to detect incorrect initial diagnoses, avoid unnecessary treatments, and relieve patients' symptoms.

2015-04-01

To assess the cost-effectiveness of natalizumab vs fingolimod over 2 years in relapsing-remitting multiple sclerosis (RRMS) patients and patients with rapidly evolving severe disease in Sweden. A decision analytic model was developed to estimate the incremental cost per relapse avoided of natalizumab and fingolimod from the perspective of the Swedish healthcare system. Modeled 2-year costs in Swedish kronor of treating RRMS patients included drug acquisition costs, administration and monitoring costs, and costs of treating MS relapses. Effectiveness was measured in terms of MS relapses avoided using data from the AFFIRM and FREEDOMS trials for all patients with RRMS and from post-hoc sub-group analyses for patients with rapidly evolving severe disease. Probabilistic sensitivity analyses were conducted to assess uncertainty. The analysis showed that, in all patients with MS, treatment with fingolimod costs less (440,463 Kr vs 444,324 Kr), but treatment with natalizumab results in more relapses avoided (0.74 vs 0.59), resulting in an incremental cost-effectiveness ratio (ICER) of 25,448 Kr per relapse avoided. In patients with rapidly evolving severe disease, natalizumab dominated fingolimod. Results of the sensitivity analysis demonstrate the robustness of the model results. At a willingness-to-pay (WTP) threshold of 500,000 Kr per relapse avoided, natalizumab is cost-effective in >80% of simulations in both patient populations. Limitations include absence of data from direct head-to-head studies comparing natalizumab and fingolimod, use of relapse rate reduction rather than sustained disability progression as the primary model outcome, assumption of 100% adherence to MS treatment, and exclusion of adverse event costs in the model. Natalizumab remains a cost-effective treatment option for patients with MS in Sweden. In the RRMS patient population, the incremental cost per relapse avoided is well below a 500,000 Kr WTP threshold per relapse avoided. In the rapidly evolving severe disease patient population, natalizumab dominates fingolimod.

Should high risk patients with Hodgkin's disease be singled out for heavier therapeutic regimens while low risk patients are spared such therapies?

In order to optimize the use of intensive therapy and autologous transplantation in patients with progressive Hodgkin's disease, we have examined the outcome of our initial 100 patients entered into autograft studies between 1985 and 1992. At a median follow-up of 3.6 (range 1.6-8.2) years, the actuarial progression free survival (PFS) was 46% (95% confidence intervals 33%-57%). The most significant determinant of PFS was the disease status at the time of protocol entry. Patients entered into transplant studies at the time of first untested relapse had a PFS of 61% compared with 38% in those who had failed induction chemotherapy, 25% in patients treated in > or = second untested relapse and 0% in those in a chemoresistant relapse. The reasons for failure differed, however, in that a high non-relapse mortality was seen in the > or = second untested relapse and resistant relapse groups while a high probability of relapse was observed in the induction failures and resistant relapse group. The most obvious group to target with more intensive therapeutic regimens consists of patients who have failed induction chemotherapy.

Radiotherapy in the treatment of multiple myeloma.

Bosch, A; Frias, Z

1988-12-01

Fifty-nine patients with multiple myeloma referred for treatment of painful bony lesions received irradiation to 95 local areas, and 16 of the 59 were irradiated using hemibody techniques. Pain relief was obtained in practically all of the irradiated regions. Most local areas were treated to doses of 3000 cGy in 10 to 15 fractions. Patients with generalized pain due to multiple site involvement were treated with single dose hemibody irradiation, to doses of 600 cGy to the upper hemibody, and of 800 cGy to the lower hemibody. This treatment was well tolerated and side effects minimal. Median survival from diagnosis was 30 months and the survival at 1, 3, and 5 years was 80%, 42%, and 12% respectively. Key articles on radiation therapy of multiple myeloma are reviewed and discussed. Since all patients eventually relapse after chemotherapy, the role of radiotherapy using present techniques should be fully evaluated and considered as an alternative in the primary treatment of multiple myeloma.

Patients with relapsed and refractory classical Hodgkin lymphoma (cHL) are often treated with autologous hematopoietic cell transplantation (auto-HCT). After auto-HCT, most transplant centers implement routine surveillance imaging to monitor for disease relapse; however, there is limited evidence to support this practice. In this multicenter, retrospective study, we identified cHL patients (n = 128) who received auto-HCT, achieved complete remission (CR) after transplantation, and then were followed with routine surveillance imaging. Of these, 29 (23%) relapsed after day 100 after auto-HCT. Relapse was detected clinically in 14 patients and with routine surveillance imaging in 15 patients. When clinically detected relapse was compared with to radiographically detected relapse respectively, the median overall survival (2084 days [range, 225-4161] vs. 2737 days [range, 172-2750]; P = .51), the median time to relapse (247 days [range, 141-3974] vs. 814 days [range, 96-1682]; P = .30) and the median postrelapse survival (674 days [range, 13-1883] vs. 1146 days [range, 4-2548]; P = .52) were not statistically different. In patients who never relapsed after auto-HCT, a median of 4 (range, 1-25) surveillance imaging studies were performed over a median follow-up period of 3.5 years. A minority of patients with cHL who achieve CR after auto-HCT will ultimately relapse. Surveillance imaging detected approximately half of relapses; however, outcomes were similar for those whose relapse was detected using routine surveillance imaging versus detected clinically in between surveillance imaging studies. There appears to be limited utility for routine surveillance imaging in cHL patients who achieve CR after auto-HCT. Copyright © 2017 Elsevier Inc. All rights reserved.

Schizophrenia is a severe, chronic psychiatric disorder. After recovery from a first psychotic episode, 70% of patients have exacerbations. These exacerbations are preceded in 66 to 100% of cases by early signs. Prevention of relapses is the main object of dealing with schizophrenia. In fact, after a psychotic relapse, 17% of patients develop residual symptoms which did not exist before the relapse. Moreover, symptoms resistant to antipsychotics appear in 35% of patients after a relapse. Each relapse increases the risk of future relapses. Finally, the cost of treating patients with relapses is four times higher than in patients without relapses. Prevention of relapses is possible if we detect early signs. In fact, when specific interventions are applied in time, relapses can be avoided. Surprisingly, there is a scarcity of data on prodromal symptoms of schizophrenic relapses in the literature. In this study, we aimed to describe early signs of schizophrenic relapses, which are comparatively more frequent than those in stabilized outpatients. We conducted a retrospective, descriptive and comparative trial. We included 30 patients with schizophrenia who had recently experienced a psychotic relapse and a member of their families. We also included a control group of 30 stabilized outpatients with schizophrenia. All of the patients were diagnosed schizophrenic according to the DSM IV and had no secondary diagnosis. Only patients aged from 18 to 55 years and having an illness with an episodic evolution were included. The relapse group must have had a period off illness of more than one year and duration of the last remission greater than 3 months. We built a structured interview based on the data of the literature on early symptoms of relapses and on our clinical experience. It contained 93 items describing symptoms and feelings relevant to the period of relapse. The interview lasted about 1h. We collected demographic information from both groups. The relapse group was composed of 21 men and nine women. Their average age was 34 years and their level of education was 9.3 years. The mean number of hospitalizations was 3.8 and 73.3% of patients had interrupted their medication. The stabilized outpatients group included 25 men and five women with an average age of 40.3 years. The mean level of education was 8.3 years, the number of hospitalizations was 2.7 and 16.7% of patients had interrupted their medication. The mean time interval between the beginning of symptoms and the need for hospitalization was 160.5 days. The more frequent symptoms in the relapse group than in stabilized patients were: overinvested ideas/delusions (93.3% of relapsing patients), trouble sleeping (80%), symptoms of disorganization (80%), and excitement/mood changes (73.3%). Globally, non-specific symptoms precede specific symptoms (149.4 days vs. 94.8 days). The earlier signs were influence syndrome (113.4 days before relapse), verbal aggressions against others (108.1 days) and suicidal thoughts (94.8 days). The latest signs were physical aggression against others (37.3 days), unmotivated smiles (35.4 days), aggression against self (35 days), strange thoughts (30.7 days) and breaking things (25.3 days). The time between perception of symptoms and hospitalization in schizophrenic patients in this study was very long (approximately 6 months). Non-psychotic prodromal symptoms precede psychotic symptoms. We recommend a major focus on teaching the patient and his/her family how to recognize early signs of decompensation and what steps to take to ensure effective treatment. We also recommend further research to determine the predictive positive value of early signs of relapse. Copyright © 2011 L’Encéphale, Paris. Published by Elsevier Masson SAS. All rights reserved.

Rituximab is used to deplete B cells and control disease activity, mainly in patients with rheumatoid arthritis (RA) who have not responded to anti-tumor necrosis factor (TNF) therapy. Response rates and time to relapse vary significantly among treated individuals. The objective of this study was to monitor the response of seropositive and seronegative RA patients to rituximab and correlate relapse with B-cell markers in the two groups. Seventeen RA patients (eight seropositive for rheumatoid factor [RF+] and nine seronegative [RF-]) were treated with two cycles of rituximab. After treatment, all patients were re-evaluated at the outpatient clinic, and rituximab was readministered when disease relapse was confirmed by clinical-laboratory measures (Disease Activity Score [DAS]-28). CD20+ cells and CD20 receptor expression levels were estimated at initiation, relapse, and re-evaluation timepoints, and were compared between the two groups. Seropositive patients responded favorably to treatment compared with the seronegative group. The mean time to relapse was 337.5 +/- 127.0 days for the RF+ patients versus 233.3 +/- 59.6 days for the RF- patients (p = 0.043), despite more aggressive concomitant treatment in the seronegative group. The DAS28 decrease 3 months after treatment was 1.695 +/- 1.076 in seropositive patients versus 0.94 +/- 1.62 in seronegative patients. At relapse, CD20 receptor expression (molecules/cell) was higher in RF+ patients than in their RF- counterparts, despite a significantly lower percentage of CD20+ cells. Rituximab treatment is efficient in both seropositive and seronegative RA. However, seropositive RA patients tend to respond favorably compared with seronegative patients. The differential CD20 receptor expression in the two groups at relapse potentially suggests a different pathogenetic mechanism of relapse and merits further investigation.

Matrix metalloproteinases are involved in neuroinflammatory processes, which could underlie depression. Serum levels of MMP-9 and MMP-2 in depressed patients are significantly altered following electroconvulsive therapy, but an association between altered matrix metalloproteinases after successful ECT and possible relapse has yet to be investigated. Serum was obtained twice, before and immediately after a course of electroconvulsive therapy, from 38 depressed patients. Serum was also collected, once, from two groups of age- and gender-matched healthy controls, 40 volunteers in each group. Possible associations between levels of matrix metalloproteinases and relapse during a 1-year follow-up period were analyzed. Excluding patients who did not respond to electroconvulsive therapy and patients lost to follow-up, data from 28 patients were evaluated. Eighteen of the patients (64.3%) relapsed within 1 year. In the group that did not relapse, serum levels of MMP-9 were significantly decreased after a course of electroconvulsive therapy, but not in the group that relapsed. No association between MMP-2 and relapse was observed. The degree of change in serum MMP-9 change could be associated with relapse following electroconvulsive therapy in depressed patients. © The Author 2017.

Despite advances in adjuvant chemotherapy, 20-30% of patients in stages II-III colorectal cancer will eventually relapse. Observational studies showed a reduction in relapse rate, colon cancer-specific mortality, and overall mortality by physical activity. Results from prospective randomized interventional studies to confirm these observational data are lacking. The aims of this prospective single-arm multicenter pilot study are to evaluate feasibility and safety of exercise training after adjuvant chemotherapy in colorectal cancer patients. The training was performed three times per week for 1 year and was increased gradually in three phases until reaching 18 metabolic equivalent task hours per week. Overall, 30 patients were included. The planned training intensity could be achieved in all three phases. Patients experienced a performance increase of median 35.5 watt, a weight-loss of a median of 3.0 kg, and a reduction in body fat content of median 1.0% during this exercise training. The analysis showed early study termination due to non-compliance in 10/30 patients (33.3%), disease progression in 4 patients (13.3%), and serious adverse events in 2 patients (6.7%). About half of patients (46.7%) completed the pilot study as planned. Biomarker analysis from 20 patients showed a non-significant reduction in insulin-like growth factor 1 (IGF-1), insulin-like growth factor 2 (IGF-2) and insulin-like growth factor binding protein 3 (IGF-BP3) levels, significant increases in adiponectin and leptin levels, and a non-significant increase in C-peptide levels. Exercise training is feasible in patients with colorectal cancer after completion of adjuvant chemotherapy. The main problem encountered during the study was compliance. To improve compliance of exercise training, several measures were adapted for the upcoming prospective randomized ABCSG C08 Exercise II study.

We investigated the frequency, predictors, and evolution of acute lymphoblastic leukemia (ALL) in patients with CNS relapse and introduced a novel method for studying BCR-ABL1 protein variants in cDNA from bone marrow (BM) and cerebrospinal fluid (CSF) blast cells. A total of 128 patients were analyzed in two PETHEMA clinical trials. All achieved complete remission after imatinib treatment. Of these, 30 (23%) experienced a relapse after achieving complete remission, and 13 (10%) had an isolated CNS relapse or combined CNS and BM relapses. We compared the characteristics of patients with and without CNS relapse and further analyzed CSF and BM samples from two of the 13 patients with CNS relapse. In both patients, classical sequencing analysis of the kinase domain of BCR-ABL1 from the cDNA of CSF blasts revealed the pathogenic variant p.L387M. We also performed ultra-deep next-generation sequencing (NGS) in three samples from one of the relapsed patients. We did not find the mutation in the BM sample, but we did find it in CSF blasts with 45% of reads at the time of relapse. These data demonstrate the feasibility of detecting BCR-ABL1 mutations in CSF blasts by NGS and highlight the importance of monitoring clonal evolution over time.

We report the characteristics of relapse, treatment response, and outcomes of 145 elderly patients with multiple myeloma in first relapse after front-line treatment with VMP or VTP. Reappearance of CRAB symptoms (113 patients) and more aggressive forms of disease (32 patients) were the most common patterns of relapse. After second-line therapy, 75 (51.7%) patients achieved at partial response and 16 (11%) complete response (CR). Overall survival was longer among patients receiving VMP as front-line induction (21.4 vs. 14.4 months, P=0.037), in patients achieving CR (28.3 vs. 14.8 months; P=0.04), and in patients without aggressive relapse (28.6 vs. 7.6 months; P=0.0007).

Following inguinal orchidectomy, management options for patients with stage I seminoma include initial surveillance or treatment with adjuvant radiotherapy or chemotherapy. The anticipated relapse rate for patients followed by surveillance alone is ∼15%, with adjuvant treatment this risk is reduced to ∼4%-5% at 5 years. After carboplatin treatment, follow-up strategies vary and there are no validated, predictive markers of relapse. We conducted a retrospective analysis of all patients presenting with stage I seminoma who received a single cycle of adjuvant carboplatin in South Central England between 1996 and 2013. We report on outcome and the results of univariate and multivariate analysis evaluating possible risk factors for post carboplatin relapse. A total of 517 eligible patients were identified. All underwent nuclear medicine estimation of glomerular filtration rate before treatment with carboplatin (dosed at area under the curve × 7). With a median follow-up of 47.2 months (range 0.4-214 months), 21/517 patients have relapsed resulting in a 5-year estimated relapse-free survival of 95.0% (95% confidence interval 92.8% to 97.3%). Median time to relapse was 22.7 months (range 12.5-109.5 months). Relapse beyond 3 years was rare (4/517; 0.8%). Twenty of 21 (95%) relapsed patients had retroperitoneal lymph node metastases. The majority (16/21; 76%) of patients had elevated tumour markers at relapse. Twenty of 517 (3.9%) patients developed a new contralateral testicular germ-cell cancer. There were no seminoma-related deaths. Tumour size was the only variable significantly associated with an increased risk of relapse. Overall results for this large cohort of patients confirm an excellent prognosis for these patients with outcomes equivalent to those seen in prospective clinical trials. Increasing tumour size alone appears to be associated with an increased risk of post chemotherapy relapse. © The Author 2015.

Secondary central nervous system (CNS) relapse is a serious and fatal complication of diffuse large B cell lymphoma (DLBCL). Data on secondary CNS (SCNS) relapse were mostly obtained from western countries with limited data from developing countries. We analyzed the data of 2034 newly diagnosed DLBCL patients enrolled into the multi-center registry under Thai Lymphoma Study Group from setting. The incidence, September 2006 to December 2013 to represent outcome from a resource limited pattern, management, and outcome of SCNS relapse were described. The 2-year cumulative incidence (CI) of SCNS relapse was 2.7 %. A total of 729, 1024, and 281 patients were classified as low-, intermediate-, and high-risk CNS international prognostic index (CNS-IPI) with corresponding 2-year CI of SCNS relapse of 1.5, 3.1, and 4.6 %, respectively (p < 0.001). Univariate analysis demonstrated advance stage disease, poor performance status, elevated lactate dehydrogenase, presence of B symptoms, more than one extranodal organ involvement, high IPI, and high CNS-IPI group as predictive factors for SCNS relapse. Rituximab exposure and intrathecal chemoprophylaxis offered no protective effect against SCNS relapse. At the time of analysis, six patients were alive. Median OS in SCNS relapsed patients was significantly shorter than relapsed patients without CNS involvement (13.2 vs 22.6 months) (p < 0.001). Primary causes of death were progressive disease (n = 35, 63.6 %) and infection (n = 9, 16.7 %). In conclusion, although the incidence of SCNS relapse in our cohort was low, the prognosis was dismal. Prophylaxis for SCNS involvement was underused even in high-risk patients. Novel approaches for SCNS relapse prophylaxis and managements are warranted.

To perform a meta-analysis of the risk of relapse after discontinuation of anti-tumor necrosis factor (anti-TNF) therapy in patients with Crohn's disease (CD) and ulcerative colitis (UC), to evaluate risk factors for relapse, and to assess the response to retreatment with the same anti-TNF. Studies evaluating the incidence of relapse after anti-TNF discontinuation in patients with CD or UC who reached clinical remission with anti-TNFs were included. Bibliographies up to January 2015 were searched. Frequency of relapse after discontinuation of anti-TNF agents was determined; meta-analyses were performed using the inverse-variance method. We included 27 studies (21 infliximab and 6 infliximab/adalimumab). The overall risk of relapse after discontinuation of anti-TNF therapy was 44% for CD (95% confidence interval (CI) 36-51%; I(2)=79%; 912 patients) and 38% for UC (23-52%; I(2)=82%; 266 patients). In CD, the relapse rate was 38% at 6 months after discontinuation (short term), 40% at 12 months (medium term), and 49% at >25 months (long term). In UC, 28% of patients relapsed at 12 months. In CD, when clinical remission was the only criterion for stopping anti-TNF therapy, the relapse rate after 1 year was 42%, which decreased to 26% when endoscopic remission was also required. Retreatment with the same anti-TNF induced remission again in 80% of cases (68-91%). Approximately one-third of patients with inflammatory bowel disease in remission under anti-TNF treatment relapsed 1 year after discontinuation. This proportion increased to half in the long term. In CD patients, the risk of relapse was lower when the criterion for discontinuation was endoscopic remission and not only clinical remission. Response to retreatment with the same anti-TNF agent was favorable.

Electroconvulsive therapy (ECT) is an effective treatment for depression and schizophrenia. However, there is a high rate of relapse after an initial response to ECT, even with antidepressant or antipsychotic maintenance therapy. This study was carried out to examine the factors that influence the risk of relapse in schizophrenic patients after a response to ECT. We retrospectively reviewed the records of 43 patients with schizophrenia who received and responded to an acute ECT course. We analyzed the associated clinical variables and relapse after response to the acute ECT. Relapse was defined as a Clinical Global Impressions Improvement score ≥6 or a psychiatric rehospitalization. All patients were treated with neuroleptic medication after the acute ECT course. The relapse-free rate of all 43 patients at 1 year was 57.3%, and the median relapse-free period was 21.5 months. Multivariate analysis showed that the number of ECT sessions was associated with a significant increase in the risk of relapse (hazard ratio: 1.159; P=0.033). Patients who were treated with adjunctive mood stabilizers as maintenance pharmacotherapy after the response to the acute ECT course were at a lower risk of relapse than were those treated without mood stabilizers (hazard ratio: 0.257; P=0.047). Our study on the recurrence of schizophrenia after a response to an acute ECT course suggests that the number of ECT sessions might be related to the risk of relapse and that adjunctive mood stabilizers might be effective in preventing relapse.

Although current therapies for acute promyelocytic leukemia (APL), such as all- trans retinoic acid and arsenic trioxide, usually result in remission, some patients relapse. Early recognition of relapse is critical for prompt intervention. In this study, we systematically reviewed morphologic, immunophenotypic, and cytogenetic findings in paired diagnostic and relapsed APL cases and describe and quantify the changes in blast morphology at relapse. By electronic database search, we identified eight paired diagnostic and relapsed APL cases for which peripheral blood or bone marrow smears were available for review. For two cases, diagnostic material was available for relapse after hematopoietic cell transplantation. Neoplastic hypergranular or microgranular promyelocytes with indented or bivalve nuclei predominated at diagnosis in all patients. Most patients had undifferentiated blasts at relapse and/or hypergranular blast equivalents with round to oval nuclei. Classic acute promyelocytic leukemia cells with bivalve nuclei and bundles of cytoplasmic Auer rods were easily identifiable in fewer than half of cases at diagnosis and rare to absent in all relapsed cases. Morphologic features of relapsed APL overlap with other types of acute myeloid leukemia, creating diagnostic challenges, especially if no history is available when relapsing patients seek treatment for care. © American Society for Clinical Pathology, 2017.

Relapses are observed in most hepatitis B e antigen (HBeAg)-negative chronic hepatitis B patients who discontinue treatment with nucleos(t)ide analogues (NAs); however, the rates of relapse vary widely among studies, and whether all patients with relapse need retreatment is unclear. The aim of this study was to assess the impact of different definitions on the rates of posttreatment relapse and therefore on the probability of retreatment in patients who have discontinued effective long-term NA therapy. In total, 130 HBeAg-negative chronic hepatitis B patients without cirrhosis and before NA treatment were included. All had on-therapy virological remission for ≥24 months and close follow-up for ≥12 months after stopping NA treatment or until retreatment, which started on stringent predefined criteria. Relapses rates based on several predetermined definitions of virological and perhaps biochemical criteria were assessed. The median duration of therapy was 60 months and the median duration of on-therapy virological remission was 43 months. During a median off-NAs follow-up of 15 months, no patient experienced liver decompensation or died. Cumulative relapse rates were 2%-49%, 4%-73%, 11%-82%, and 16%-90% at 3, 6, 12, and 24 months, respectively, whereas cumulative retreatment rates were 15%, 22%, and 40% at 6, 12, and 24 months, respectively, after discontinuation of NA therapy. No patient characteristic was independently associated with the probability of relapse based on at least two definitions or of retreatment. In HBeAg-negative chronic hepatitis B patients who discontinue NA therapy, the definition of relapse has a great impact on off-NAs relapse rates and potentially on the probability of retreatment. Regardless of definition, off-NAs relapses cannot be easily predicted by patient characteristics. A substantial proportion of such patients may not require retreatment if stringent criteria are adopted. (Hepatology 2017). © 2017 by the American Association for the Study of Liver Diseases.

Patients on surveillance for clinical stage I (CSI) testicular cancer are counseled regarding their baseline risk of relapse. The conditional risk of relapse (cRR), which provides prognostic information on patients who have survived for a period of time without relapse, have not been determined for CSI testicular cancer. To determine cRR in CSI testicular cancer. We reviewed 1239 patients with CSI testicular cancer managed with surveillance at a tertiary academic centre between 1980 and 2014. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS: cRR estimates were calculated using the Kaplan-Meier method. We stratified patients according to validated risk factors for relapse. We used linear regression to determine cRR trends over time. At orchiectomy, the risk of relapse within 5 yr was 42.4%, 17.3%, 20.3%, and 12.2% among patients with high-risk nonseminomatous germ cell tumor (NSGCT), low-risk NSGCT, seminoma with tumor size ≥3cm, and seminoma with tumor size <3cm, respectively. However, for patients without relapse within the first 2 yr of follow-up, the corresponding risk of relapse within the next 5 yr in the groups was 0.0%, 1.0% (95% confidence interval [CI] 0.3-1.7%), 5.6% (95% CI 3.1-8.2%), and 3.9% (95% CI 1.4-6.4%). Over time, cRR decreased (p≤0.021) in all models. Limitations include changes to surveillance protocols over time and few late relapses. After 2 yr, the risk of relapse on surveillance for CSI testicular cancer is very low. Consideration should be given to adapting surveillance protocols to individualized risk of relapse based on cRR as opposed to static protocols based on baseline factors. This strategy could reduce the intensity of follow-up for the majority of patients. Our study is the first to provide data on the future risk of relapse during surveillance for clinical stage I testicular cancer, given a patient has been without relapse for a specified period of time.

Patients with relapsed lymphoma can be cured with high-dose chemotherapy and autologous hematopoietic stem cell transplantation (HSCT). New therapeutic approaches with better cytoreductive capacity are needed for relapsed patients to keep their chance for cure with transplantation. We report 30 patients with relapsed lymphoma, median age 43 years, treated with IIVP salvage regimen consisting of ifosfamide, mesna, idarubicin, and etoposide for 2 or 3 cycles. Seventeen patients had non-Hodgkin lymphoma (NHL) and 13 patients had Hodgkin disease (HD). Fourteen (47%) patients were at their first relapse. Overall response rate was 86.6% (n = 26) with 19 patients (63.3%) achieving complete response. Overall response rate was 92% in patients with HD and 82% in NHL. The most frequent side effects observed were grade III-IV neutropenia (87%) and thrombocytopenia (73%). IIVP regimen is a highly effective salvage therapy for patients with relapsed HD or NHL who are candidates for autologous HSCT. Close follow up is necessary because of the high incidence of grade III-IV hematologic toxicity.

To investigate the social factors of patients with genital herpes (GH) relapsing and guide GH patients to avoid the related social factors. To select 96 case of patients with recurrent genital herpes of final diagnosis and detailedly record the related social factors before relapsing. The social factors were compared between male and female GH patients, and compared between frequently recurrent (> 6/year) and non-frequently recurrent GH patients (< or = 6/year) too. 65.6% (63/96) of recurrent GH patients have certain social factors before relapsing. The main social factors are overtiredness, mental stress and excessive sexual contact. Staying up late and excessive drinking are common social factors, too. There was no significant difference of social factors between male and female GH patients (P >. 05), and also no significant difference between frequently recurrent and non-frequently recurrent GH patients (P > 0.05), too. Overtiredness, mental stress and excessive sexual are the main social elements during inducing genital herpes relapsing. It is important to reduce GH relapsing and spreading of HIV and syphilis by guiding recurrent genital herpes patients to avoid related social elements.

The mainstay of treatment for thrombotic thrombocytopenic purpura (TTP) is plasma exchange (PE), but the role of splenectomy is still undefined. The records of all patients with TTP at a single center over a 20-year period were retrospectively reviewed. Response to plasma exchange was determined. The outcome of patients treated with splenectomy in the setting of TTP was evaluated. Sixty-one patients had been treated for TTP. Thirty-nine patients (64%) achieved complete remission (CR) with PE, nineteen (31%) of these achieving sustained CR and seventeen (28%) with relapsed TTP. Twenty patients (33%) had PE refractory TTP and two patients (3%) had PE dependent TTP. During this time period, 10 patients (16%) underwent splenectomy, four patients (7%) for PE dependent TTP, three (5%) for relapsed TTP, and three (5%) for refractory TTP. All of the patients achieved CR after splenectomy. Two patients who had undergone splenectomy had subsequent relapses, both with previously relapsed TTP. In relapsed patients the relapse rate after splenectomy was 0.27 events per patient year compared to 0.6 events per patient year before splenectomy. Median follow-up after splenectomy was 19 months (range 0.13-90 months). In conclusion, relapses in TTP can be managed successfully with additional PE or with splenectomy. PE dependent or refractory TTP can be successfully treated with splenectomy.

Purpose Therapeutic targeting of Bruton tyrosine kinase (BTK) with ibrutinib in chronic lymphocytic leukemia has led to a paradigm shift in therapy, and relapse has been uncommon with current follow-up. Acquired mutations in BTK and PLCG2 can cause relapse, but data regarding the prevalence and natural history of these mutations are limited. Patients and Methods Patients accrued to four sequential studies of ibrutinib were included in these analyses. Deep sequencing for BTK and PLCG2 was performed retrospectively on patients who experienced relapse and prospectively on a screening population. Results With a median follow-up time of 3.4 years, the estimated cumulative incidence of progression at 4 years is 19% (95% CI, 14% to 24%). Baseline karyotypic complexity, presence of del(17)(p13.1), and age less than 65 years were risk factors for progression. Among patients who experienced relapse, acquired mutations of BTK or PLCG2 were found in 85% (95% CI, 71% to 94%), and these mutations were detected an estimated median of 9.3 months (95% CI, 7.6 to 11.7 months) before relapse. Of a group of 112 patients examined prospectively, eight patients have experienced relapse, and all of these patients had acquired resistance mutations before relapse. A resistance mutation was detected in an additional eight patients who have not yet met criteria for clinical relapse. Conclusion Relapse of chronic lymphocytic leukemia after ibrutinib is an issue of increasing clinical significance. We show that mutations in BTK and PLCG2 appear early and have the potential to be used as a biomarker for future relapse, suggesting an opportunity for intervention. PMID:28418267

Relapses of nephrotic syndrome often follow minor infections, commonly of the upper respiratory tract. Daily administration of maintenance prednisolone during intercurrent infections was examined to determine whether the treatment reduces relapse rates in children with frequently relapsing nephrotic syndrome. In a randomized controlled trial (nonblind, parallel group, tertiary-care hospital), 100 patients with idiopathic, frequently relapsing nephrotic syndrome eligible for therapy with prolonged low-dose, alternate-day prednisolone with or without levamisole were randomized to either receive their usual dose of alternate-day prednisolone daily for 7 days during intercurrent infections (intervention group) or continue alternate-day prednisolone (controls). Primary outcome was assessed by comparing the rates of infection-associated relapses at 12-month follow-up. Secondary outcomes were the frequency of infections and the cumulative amount of prednisolone received in both groups. Patients in the intervention group showed significantly lower infection-associated (rate difference, 0.7 episodes/patient per year; 95% confidence intervals [CI] 0.3, 1.1) and lower total relapse rates (0.9 episodes/patient per year, 95% CI 0.4, 1.4) without increase in steroid toxicity. Poisson regression, adjusted for occurrence of infections, showed that daily administration of prednisolone during infections independently resulted in 59% reduction in frequency of relapses (rate ratio, 0.41; 95% CI 0.3, 0.6). For every six patients receiving this intervention, one showed a reduction of relapse frequency to less than three per year. Daily administration of maintenance doses of prednisolone, during intercurrent infections, significantly reduces relapse rates and the proportion of children with frequently relapsing nephrotic syndrome.

The complement inhibitor eculizumab has dramatically improved the outcome of atypical hemolytic uremic syndrome. However, the optimal duration of eculizumab treatment in atypical hemolytic uremic syndrome remains debated. We report on the French atypical hemolytic uremic syndrome working group's first 2-year experience with eculizumab discontinuation in patients with atypical hemolytic uremic syndrome. Using the French atypical hemolytic uremic syndrome registry database, we retrospectively identified all dialysis-free patients with atypical hemolytic uremic syndrome who discontinued eculizumab between 2010 and 2014 and reviewed their relevant clinical and biologic data. The decision to discontinue eculizumab was made by the clinician in charge of the patient. All patients were closely monitored by regular urine dipsticks and blood tests. Eculizumab was rapidly (24-48 hours) restarted in case of relapse. Among 108 patients treated with eculizumab, 38 patients (nine children and 29 adults) discontinued eculizumab (median treatment duration of 17.5 months). Twenty-one patients (55%) carried novel or rare complement genes variants. Renal recovery under eculizumab was equally good in patients with and those without complement gene variants detected. After a median follow-up of 22 months, 12 patients (31%) experienced atypical hemolytic uremic syndrome relapse. Eight of 11 patients (72%) with complement factor H variants, four of eight patients (50%) with membrane cofactor protein variants, and zero of 16 patients with no rare variant detected relapsed. In relapsing patients, early reintroduction (≤48 hours) of eculizumab led to rapid (<7 days) hematologic remission and a return of serum creatinine to baseline level in a median time of 26 days. At last follow-up, renal function remained unchanged in nonrelapsing and relapsing patients compared with baseline values before eculizumab discontinuation. Pathogenic variants in complement genes were associated with higher risk of atypical hemolytic uremic syndrome relapse after eculizumab discontinuation. Prospective studies are needed to identify biomarkers predictive of relapse and determine the best strategy of retreatment in relapsing patients.

PubMed

2015-06-01

In the last decade, gamma-hydroxybutyrate (GHB) abuse and dependence have increased. It has been reported that GHB dependence has a high rate of relapse, serious complications of intoxication, and a potentially life-threatening withdrawal syndrome. Nevertheless, in clinical practice, there is no known medical treatment to support GHB relapse prevention. We describe a case series of patients who were supported through an off-label treatment with baclofen to avoid a relapse into GHB abuse, for a period of 12 weeks. Nine of 11 patients did not relapse while taking a dose ranging from 30 to 60 mg per day, one patient relapsed after 5 weeks, and one stopped after 7 weeks. Baclofen was well tolerated; patients reported mild side effects such as fatigue, nausea, dry mouth, excessive sweating, and depressive feelings. Although systematic evidence is still lacking, our practice-based experience suggests that treatment with baclofen to assist abstinence might be effective in patients with GHB dependence. Further systematic controlled studies are necessary to establish the exact efficacy and safety of baclofen as relapse prevention for GHB-dependent patients.

In this study we investigated the correlation between donor chimerism status and disease relapse following allogeneic hematopoietic stem cell transplantation (allo-HSCT). The chimerism of Fluorescence-activated cell sorter (FACS) sorted CD3+T lymphocytes of 153 cases, CD56+CD16+NK lymphocytes of 153 cases and CD19+B lymphocytes of 31 cases with acute B lymphoblastic leukemia (B-ALL) was analyzed post-transplant utilizing polymerase chain reaction amplification of short tandem repeats (PCR-STR). A total of 33 patients (33/153, 21.6%) had recurrent disease. The positive predictive values of declining donor chimerism for hematologic and isolated extramedullary relapse were 58.8% and 10% (P=0.018, Chi-Square). The positive predictive values of declining donor chimerism in BMB, BMT, BMNK and PBB for hematologic relapse were 11.6%, 0%, 0% and 0% under close monitoring in patients with B-ALL. Only the donor chimerism in BMB significantly decreased in the group with hematologic relapse as compared with the group without hematologic relapse (P=0.00, Independent-samples T test) in patients with B-ALL. The median drop of donor chimerism in PBT, BMT, PBNK and BMNK were 0%, 0%, 5.9% and 2.8% one or two weeks prior to hematologic relapse in patients with non-B-ALL. The donor chimerism in PBNK significantly decreased prior to hematologic relapse in the group with hematologic relapse as compared with the group without hematologic relapse (P=0.022, Independent-samples T test).These data suggest donor chimerism of BMB can be used to predict the occurrence of hematologic relapse in patients with B-ALL. Donor chimerism decrease in PBNK was associated with a somewhat increased risk of hematologic relapse in patients with non-B-ALL. Therefore, our results reveal a more effective path to individually predict for hematologic relapse by dynamic monitoring different cell lineages in different disease.

Central nervous system (CNS) relapse is an uncommon but challenging complication in patients with mantle cell lymphoma (MCL). Survival after CNS relapse is extremely poor. Identification of high-risk populations is therefore critical in determining patients who might be candidates for a prophylactic approach. A total of 608 patients (median age, 67 years; range 22-92) with MCL newly diagnosed between 1994 and 2012 were evaluated. Pretreatment characteristics and treatment regimens were evaluated for their association with CNS relapse by competing risk regression analysis. None of the patients received intrathecal prophylaxis. Overall, 33 patients (5.4%) experienced CNS relapse during a median follow-up of 42.7 months. Median time from diagnosis to CNS relapse was 20.3 months (range: 2.2-141.3 months). Three-year cumulative incidence of CNS relapse was 5.6% [95% confidence interval (95% CI) 3.7% to 8.0%]. Univariate analysis revealed several risk factors including blastoid variant, leukemic presentation, high-risk MCL International Prognostic Index and high Ki-67 (proliferation marker). Multivariate analyses revealed that Ki-67 ≥ 30 was the only significant risk factor for CNS relapse (hazard ratio: 6.0, 95% CI 1.9-19.4, P = 0.003). Two-year cumulative incidence of CNS relapse in patients with Ki-67 ≥ 30 was 25.4% (95% CI 13.5-39.1), while that in the patients with Ki-67 < 30 was 1.6% (95% CI 0.4-4.2). None of the treatment modalities, including rituximab, high-dose cytarabine, high-dose methotrexate or consolidative autologous stem-cell transplant, were associated with a lower incidence of CNS relapse. Survival after CNS relapse was poor, with median survival time of 8.3 months. There was no significant difference in the survival by the site of CNS involvement. © The Author 2015.

Despite persistence of leukemic stem cells, patients with chronic myeloid leukemia who achieve and maintain deep molecular responses may successfully stop the tyrosine kinase inhibitor imatinib. However, questions remain unanswered regarding the biological basis of molecular relapse after imatinib cessation. In IMMUNOSTIM, we monitored 51 patients from the French Stop IMatinib trial for peripheral blood T cells and natural killer cells. Molecular relapse-free survival at 24 months was 45.1% (95% CI: 31.44%-58.75%). At the time of imatinib discontinuation, non-relapsing patients had significantly higher numbers of natural killer cells of the cytotoxic CD56 dim subset than had relapsing patients, while CD56 bright natural killer cells, T cells and their subsets did not differ significantly. Furthermore, the CD56 dim natural killer-cell count was an independent prognostic factor of molecular-relapse free survival in a multivariate analysis. However, expression of natural killer-cell activating receptors, BCR-ABL1 + leukemia cell line K562-specific degranulation and cytokine-induced interferon-gamma secretion were decreased in non-relapsing and relapsing patients as compared with healthy individuals. After imatinib cessation, the natural killer-cell count increased significantly and stayed higher in non-relapsing patients than in relapsing patients, while receptor expression and functional properties remained unchanged. Altogether, our results suggest that natural killer cells may play a role in controlling leukemia-initiating cells at the origin of relapse after imatinib cessation, provided that these cells are numerous enough to compensate for their functional defects. Further research will decipher mechanisms underlying functional differences between natural killer cells from patients and healthy individuals and evaluate the potential interest of immunostimulatory approaches in tyrosine kinase inhibitor discontinuation strategies.

To assess efficacy and safety of rituximab (RTX) as induction therapy, maintenance of remission and treatment of relapses in a cohort of IgG4-related disease (IgG4-RD) patients. Nationwide retrospective multicenter study of IgG4-RD patients treated with at least one course of RTX. Clinical, biological and radiological response, relapse rate and drug tolerance were analyzed. Kaplan-Meier curves were plotted and risk factors for relapse studied with a Cox regression model. Among 156 IgG4-RD patients included in the French database, 33 received rituximab. Clinical response was noted in 29/31 (93.5%) symptomatic patients. Glucocorticoids withdrawal was achieved in 17 (51.5%) patients. During a mean follow-up of 24.8 ±21 months, 13/31 (41.9%) responder patients relapsed after a mean delay of 19 ±11 months after RTX. Active disease, as defined by an IgG4-RD Responder Index >9 before RTX, was significantly associated with relapse (HR = 3.68, 95% CI: 1.1, 12.6) (P = 0.04), whereas maintenance therapy with systematic (i.e. before occurrence of a relapse) RTX retreatment was associated with longer relapse-free survival (41 versus 21 months; P = 0.02). Eight severe infections occurred in 4 patients during follow-up (severe infections rate of 12.1/100 patient-years) and hypogammaglobulinemia ≤5 g/l in 3 patients. RTX is effective for both induction therapy and treatment of relapses in IgG4-RD, but relapses are frequent after B-cell reconstitution. Maintenance therapy with systematic RTX infusions is associated with longer relapse-free survival and might represent a novel treatment strategy. Yet, the high rate of infections and the temporary effect of RTX might be hindrances to such strategy.

The objective of this study was to create a clinically useful tool for individualized prediction of seizure outcomes following antiepileptic drug withdrawal after pediatric epilepsy surgery. We used data from the European retrospective TimeToStop study, which included 766 children from 15 centers, to perform a proportional hazard regression analysis. The 2 outcome measures were seizure recurrence and seizure freedom in the last year of follow-up. Prognostic factors were identified through systematic review of the literature. The strongest predictors for each outcome were selected through backward selection, after which nomograms were created. The final models included 3 to 5 factors per model. Discrimination in terms of adjusted concordance statistic was 0.68 (95% confidence interval [CI] 0.67-0.69) for predicting seizure recurrence and 0.73 (95% CI 0.72-0.75) for predicting eventual seizure freedom. An online prediction tool is provided on www.epilepsypredictiontools.info/ttswithdrawal. The presented models can improve counseling of patients and parents regarding postoperative antiepileptic drug policies, by estimating individualized risks of seizure recurrence and eventual outcome.

Purpose: To evaluate the clinical outcome of salvage treatment for patients with relapsed natural killer (NK)/T-cell lymphoma, nasal type. Methods and Materials: Forty-four patients who had achieved complete response during initial treatment and experienced histologically proven relapse were reviewed. Twenty-nine of them received salvage treatment with radiotherapy (RT) alone (n = 7), chemotherapy (CT) alone (n = 10), or both RT and CT (n = 12); the other 15 patients received best supportive care alone. Results: The estimated 5-year overall survival (OS) rate for patients with or without salvage treatment was 37.8% vs. 0 (p < 0.0001), respectively. Salvage CTmore » did not improve survival of relapsed Stage IE and IIE patients. Among relapsed Stage IIIE and IVE patients who received salvage treatment, RT developed significantly better survival when compared with that of non-RT (1-year OS, 62.5% vs. 0, p = 0.006). Relapsed Ann Arbor stage and receiving salvage treatment were found to be significant factors influencing OS at both univariate and multivariate levels. Conclusions: Salvage treatment improved survival in patients with relapsed NK/T-cell lymphoma, nasal type. Salvage RT may play an important role in salvage treatment of relapsed extranodal NK/T-cell lymphoma.« less

We reported a case of relapsing immune-related colitis (initially caused by nivolumab) following osimertinib therapy for lung adenocarcinoma. A 45-year-old female who had never smoked was diagnosed with adenocarcinoma of the lung and underwent surgical resection. Four years after surgical resection, she was diagnosed with recurrent disease and was eventually treated with nivolumab as third-line therapy. One month after the completion of nivolumab therapy, the patient reported abdominal pain and frequent diarrhea. We diagnosed immune-related colitis and started oral prednisolone. However, the steroid therapy was ineffective, so the patient was administered infliximab and an increased dose of prednisolone. Her symptoms subsequently resolved, and her mucosal lesions improved. Six months after the last administration of nivolumab, osimertinib was initiated as fourth-line therapy, but 3 days later, the patient developed blood in the stool and frequent diarrhea. Osimertinib treatment was discontinued, given the possibility that it had reactivated the patient's immune-related colitis. We subsequently re-administered oral prednisolone (2 mg/kg/day), and the colitis resolved within a few weeks.

Patients with multiple sclerosis (MS) who are of African descent experience a more aggressive disease course than patients who are of white race/ethnicity. In phase 3 clinical trials (Natalizumab Safety and Efficacy in Relapsing Remitting Multiple Sclerosis [AFFIRM] and Safety and Efficacy of Natalizumab in Combination With Interferon Beta-1a in Patients With Relapsing Remitting Multiple Sclerosis [SENTINEL]), natalizumab use significantly improved clinical and magnetic resonance imaging outcomes over 2 years in patients with relapsing MS. Because patients of African descent may be less responsive to interferon beta treatment than patients of white race/ethnicity, the efficacy of natalizumab therapy in this population is clinically important. To evaluate the efficacy of natalizumab use in patients of African descent with relapsing MS. Post hoc analysis. Academic research. Patients of African descent with relapsing MS who received natalizumab or placebo in the phase 3 AFFIRM study and those who received natalizumab plus intramuscular interferon beta-1a or placebo plus intramuscular interferon beta-1a in the phase 3 SENTINEL study. Efficacy of natalizumab use in patients of African descent with relapsing MS who participated in the AFFIRM or SENTINEL trial. Forty-nine patients of African descent participated in AFFIRM (n = 10) or SENTINEL (n = 39). Demographic and baseline disease characteristics were similar between patients treated with natalizumab (n = 21) or placebo (n = 28). Natalizumab therapy significantly reduced the annualized MS relapse rate by 60% (0.21 vs 0.53 in the placebo group, P = .02). Compared with placebo use, natalizumab therapy also significantly reduced the accumulation of lesions observed on magnetic resonance imaging over 2 years: the mean number of gadolinium-enhancing lesions was reduced by 79% (0.19 vs 0.91, P = .03), and the mean number of new or enlarged T2-weighted lesions was reduced by 90% (0.88 vs 8.52, P = .008). Natalizumab therapy significantly improved the relapse rate and accumulation of brain lesions in patients of African descent with relapsing MS.

To determine the frequency, site and time to relapse from diagnosis, and to see the relationship of relapse with important prognostic factors. The prospective descriptive observational study was conducted at the National Institute of Child Health, Karachi, June 2005 to May 2007, and comprised newly-diagnosed cases of acute lymphoblastic leukaemia. Bone marrow aspiration was done on reappearance of blast cells in peripheral smear and cerebrospinal fluid. Detailed report was done each time when intra-thecal chemotherapy was given or there were signs and symptoms suggestive of central nervous system relapse. SPSS 12 was used for data analysis. Of the 60 patients enrolled, 4(6.6%) expired and 1(1.7%) was lost to follow-up. Of the 55(91.6%) who comprised the study sample, 35(58%) were males and 25(42%) females. Mean age of relapse was 6.8±3.27 years. Mean time to relapse from diagnosis was 1.3±0.54 years; 12(20%) patients suffered relapse, and of them 5(14%) were boys. Central nervous system relapse in 8(67%) patients was the most common site, with 3(25%) bone-marrow relapses. Out of 12 patient with relapses, 9(75%) had white blood cell count less than 50,000/cm. Relapse in acute lymphoblastic leukaemia was common, although treatment modalities are improving day by day.

The aim of this study is to diagnose the evaluation of concentration of CEA and TPS in postoperative monitoring of patients with colorectal cancer. We measured 178 consecutive patients with histopathologically confirmed colorectal cancer: 101 men and 78 women ages 22-86 (average age 54.7). Markers' CEA nad TPS concentration were evaluated before operation and every month after operation during the first 3 months and then every 3 months during 2 years. Relapse was detected in 47 patients. In postoperative period in non-relapse group the mean (the average) concentration of CEA was 1.92+/-2.03 ng/ml and TPS 65.54+/-33.96 U/l and respectively in relapse group for CEA was 1.92+/-2.03 ng/ml and for TPS 65.54+/-33.96 U/l. The obtained results in investigated group show significantly statistical. The relapse was confirmed by using CEA concentration in 42 patients (89.4%). In case of TPS concentration relapse was confirmed in 38 patients (80.85%). The relapse was detected in 45 patients (95.74) if increase in CEA or TPS concentration was treated as a way of detecting relapse. TPS markers point out that the increase of TPS concentartion may be ahead of relapse symptoms at about 2-6 months. TPS is a useful marker in postoperative monitoring of patients with colorectal cancer. The evaluation of TPS concentration allow to diagnose the recurrence of colorectal cancer earlier than by using burden markers--CEA. Common evaluation of TPS and CEA increase sensitivity in detection of relapse in patients with colorectal cancer.

Relapse of tumours in patients with oral cavity squamous cell carcinoma (OSCC) is associated with a dismal outcome. In this prospective study, we sought to investigate the clinical significance of the preoperative maximal standardized uptake value (SUVmax) at the neck lymph nodes in selecting patients with OSCC for salvage therapy after relapse. Between 2002 and 2007, 108 patients with early relapse of OSCC (n=75) or late relapse of OSCC (n=33) were identified. Salvage therapy was performed in 47 patients. All patients underwent 2-deoxy-2[(18)F]-fluoro-D: -glucose positron emission tomography during the 2 weeks before surgery and neck dissection. All patients were followed for 12 months or more after surgery or until death. The optimal cut-off value for the neck lymph node SUVmax (SUVnodal-max) was selected according to the 5-year disease-specific survival (DSS) rate. Independent risk factors were identified by Cox regression analysis. The mean follow-up for all patients was 20.3 months (41.1 months for surviving patients). In the early relapse group, several prognostic factors were identified in univariate and multivariate analyses, including a SUVnodal-max value of >or=4.2. A scoring system based on univariate analysis was formulated. Patients with a score of 0 had a better 5-year DSS than those with scores of 1 or higher (58% vs. 5%, p=0.0003). In patients with late relapse, a SUVnodal-max value of >or=4.2 had the highest prognostic value for predicting the 5-year DSS (45% vs. 0%, p=0.0005). Among patients with relapsed OSCC, the SUVnodal-max value may aid in selecting patients for salvage therapy.

Hyperthyroidism relapse in Graves disease after antithyroid drug (ATD) withdrawal is common; however, measuring the thyrotropin receptor antibody (TRAb) at ATD withdrawal in order to predict outcomes is controversial. This study compared measurement of thyroid stimulatory antibody (TSAb) and thyrotropin-binding inhibitory immunoglobulin (TBII) at ATD withdrawal to predict relapse. This retrospective study enrolled patients with Graves disease who were treated with ATDs and whose serum thyroid-stimulating hormone levels were normal after receiving low-dose ATDs. ATD therapy was stopped irrespective of TRAb positivity after an additional 6 months of receiving the minimum dose of ATD therapy. Patients were followed using thyroid function tests and TSAb (TSAb group; n=35) or TBII (TBII group; n=39) every 3 to 6 months for 2 years after ATD withdrawal. Twenty-eight patients (38%) relapsed for a median follow-up of 21 months, and there were no differences in baseline clinical characteristics between groups. In the TSAb group, relapse was more common in patients with positive TSAb at ATD withdrawal (67%) than patients with negative TSAb (17%; P=0.007). Relapse-free survival was shorter in TSAb-positive patients. In the TBII group, there were no differences in the relapse rate and relapse-free survivals according to TBII positivity. For predicting Graves disease relapse, the sensitivity and specificity of TSAb were 63% and 83%, respectively, whereas those of TBII were 28% and 65%. TSAb at ATD withdrawal can predict the relapse of Graves hyperthyroidism, but TBII cannot. Measuring TSAb at ATD withdrawal can assist with clinical decisions making for patients with Graves disease.

For predicting Graves disease relapse, the sensitivity and specificity of TSAb were 63% and 83%, respectively, whereas those of TBII were 28% and 65%. Conclusion TSAb at ATD withdrawal can predict the relapse of Graves hyperthyroidism, but TBII cannot. Measuring TSAb at ATD withdrawal can assist with clinical decisions making for patients with Graves disease. PMID:27118279

The objective of this study was to estimate the risk of a seizure relapse and the high-risk period of recurrence after antiepileptic drug (AED) withdrawal and to determine the predictive factors for a seizure relapse in adult patients with focal epilepsy who were seizure-free for more than 2years. Using the Wenzhou Epilepsy Follow-Up Registry Database, 200 adult patients with focal epilepsy were recruited, who were undergoing follow-up, met the inclusion criteria of this study, were seizure-free for more than 2years, began withdrawing between June 2003 and June 2014, and were followed up prospectively for at least 1year or until a seizure relapse. The risk of recurrence and the time to seizure relapse were analyzed by the Kaplan-Meier method, and the predictive factors were identified by the Cox proportional hazard regression model. A total of 99 patients had an unprovoked relapse during the follow-up period. The relapse rate was 49.5%, and each year, the recurrence probability of 12, 24, 36, 48, 60, 72, and 84months after AED withdrawal was 24.0%, 20.4%, 8.3%, 2.7%, 4.6%, 0.97%, and 0.98%, respectively. The two independent risk factors for recurrence after withdrawal in adult patients with focal epilepsy were a longer duration of active epilepsy and a shorter seizure-free period before withdrawal. The high-risk period of a seizure relapse in adult patients with focal epilepsy is the first 2years after withdrawal, and beyond 5years after withdrawal, seizures rarely relapse (relapse rate<1%). A seizure-free period for less than 4years before withdrawal is a predictive factor of risk for seizure recurrence after AED withdrawal in adult patients with focal epilepsy.

This study aimed to describe the patterns of care and outcomes of diffuse large B cell lymphoma (DLBCL) after failure of front line anthracycline-based immunochemotherapy (IC). Patients with newly diagnosed lymphoma were prospectively enrolled in Molecular Epidemiology Resource (MER) of the University of Iowa/Mayo Clinic Lymphoma Specialized Program of Research Excellzence. All DLBCL and primary mediastinal B-cell lymphoma (PMBL) patients treated with front-line anthracycline-based IC were followed for relapse. Patients with relapse on follow-up and subsequently retreated were included in this analysis. 1039 patients received anthracycline-based IC between 2002 and 2012, of which 244 relapsed and were subsequently retreated. Across all therapies, overall survival at 4 years (OS4) from relapse was 28% and 103 patients ultimately underwent autologous haematopoietic cell transplant (autoHCT) with OS4 from autoHCT of 51%. Patients relapsing after 12 months from initial diagnosis had OS4 of 47% but those with a transient or no response to initial therapy had OS4 of only 13%. Outcomes of relapsed or refractory DLBCL differ substantially when categorized by response to initial therapy, timing of relapse and opportunity to undergo autoHCT. The design and interpretation of uncontrolled trials should account for this heterogeneity in patients with relapsed DLBCL. © 2017 John Wiley & Sons Ltd.

S100A8/A9 (calprotectin) has shown promise as a biomarker for predicting relapse in antineutrophil cytoplasmic antibody (ANCA)-associated vasculitis (AAV). This study was undertaken to investigate serum S100A8/A9 level as a biomarker for predicting future relapse in a large cohort of patients with severe AAV. Serum levels of S100A8/A9 were measured at baseline and months 1, 2, and 6 following treatment initiation in 144 patients in the Rituximab in ANCA-Associated Vasculitis trial (cyclophosphamide/azathioprine versus rituximab [RTX] for induction of remission) in whom complete remission was attained. Patients were divided into 4 groups: proteinase 3 (PR3)-ANCA with relapse (n = 37), PR3-ANCA without relapse (n = 56), myeloperoxidase (MPO)-ANCA with relapse (n = 6), and MPO-ANCA without relapse (n = 45). Serum S100A8/A9 level decreased in all groups during the first 6 months of treatment. The percentage reduction from baseline to month 2 was significantly different between patients who experienced a relapse and those who did not in the PR3-ANCA group (P = 0.046). A significantly higher risk of relapse was associated with an increase in S100A8/A9 level between baseline and month 2 (P = 0.0043) and baseline and month 6 (P = 0.0029). Subgroup analysis demonstrated that patients treated with RTX who had increased levels of S100A8/A9 were at greatest risk of future relapse (P = 0.028). An increase in serum S100A8/A9 level by month 2 or 6 compared to baseline identifies a subgroup of PR3-ANCA patients treated with RTX who are at higher risk of relapse by 18 months. Since RTX is increasingly used for remission induction in PR3-ANCA-positive patients experiencing a relapse, S100A8/A9 level may assist in identifying those patients requiring more intensive or prolonged treatment. © 2016, American College of Rheumatology.

Survival is poor in pediatric patients with relapsed or refractory acute B-cell lymphoblastic leukemia (ALL) and therapeutic options are limited. CMC-544 (inotuzumab ozogamicin) has shown significant activity in adult patients with relapsed and refractory ALL. We evaluated CMC-544 in pediatric patients with multiply relapsed ALL. Five children 4-15 years old with relapsed, CD 22 positive B-cell ALL were enrolled on a phase II non-randomized trial of CMC-544. CMC-544 was initially administered at 1.3 mg/m(2) every 3 weeks. The dose then increased to 1.8 mg/m(2) every 3 weeks. Subsequently, a weekly schedule of CMC-544 given as 0.8 mg/m(2) on day 1 followed by 0.5 mg/m(2) on days 8 and 15 was administered. All five patients had refractory relapsed B-cell ALL. Lymphoblasts for all patients highly expressed CD22. Four patients had two or more relapses before starting the study drug. One patient achieved a complete remission in the bone marrow and normal peripheral counts, and two patients achieved bone marrow morphologic remission with absolute neutrophils >1,000/µl but platelets <100,000/µl. Two patients had no response to the drug. Toxicities consisted of fever, sepsis, and liver enzyme elevation. Single agent CMC-544 given at the single dose of 1.8 mg/m(2) every 3 weeks or given as a split, weekly dose was generally well tolerated considering the inherent risks in this population of patients and showed promising activity in pediatric patients with relapsed and refractory ALL. © 2013 Wiley Periodicals, Inc.

[Relapse in schizophrenia: an exploratory study of the joint conceptions of patients, parents and caregivers].

The question of the course of schizophrenia relapses, is of considerable interest in different clinical and social areas such as prognosis, quality of life, therapeutic relationship, psychoeducation, rehabilitation and so on. The more the schizophrenic relapses, the higher the level of handicap. Although there is a widespread agreement that it is essential to detect early signs of relapses in order to prevent them, there still remain theoretical and methodological difficulties in identifying these signs because they are personal, heterogeneous and not always specific to psychosis. That is why the notion of "relapse signature" seems relevant by taking into account differentiated and personal assessment of early signs of relapse. This implies the consideration of the different visions of relapse given by patients, parents and caregivers. We propose a qualitative study of the joint appraisal of patients, patients' parents and medical staff. The aim of this study is to regroup the expertises in order to further our understanding of the early signs of relapse. We assume that patients and parents are able to describe signs that are not considered as pathological symptoms, but refer to a personal manner of initiating the relapse process. This should then help in designing early intervention and provide reinforced therapeutic alliance and more positive responses to psychoeducation programs. We have interviewed 30 subjects divided in three groups: 10 schizophrenic patients, 10 caregivers (including physicians, psychologists and nurses) and 10 parents of schizophrenics. The patients met the following criteria: patients with a diagnosis of schizophrenia (DSM IV criteria), under neuroleptic treatment, and stabilized. The mean duration of illness was 15 years. The patients as well as caregivers were recruited in two external hospital structures. All the subjects gave their written consent for this study and its methods. We did not recruit parents who were not living with their schizophrenic child or who did not see or have frequent contact with him or her for this study. We conducted a semistructured interview and analysed the transcripts of the narratives provided by our three groups on the definition of relapse and early signs of relapse. Recorded interviews were processed using the Alceste Method, a computer program of textual analysis that identifies the word patterns most frequently used by the subjects. Alceste creates classes of words using a hierarchical descending classification. The description of each class is presented in the form of a word list (with the value of the word's Chi(2) association in this class). We assessed the awareness of problems using the 8-Q. The three groups described relapses as a distressed, even traumatic experience. This experience is shared by the patients' siblings who sometimes mention violent situations and difficulties at home. The analysis showed that each group uses a compartmentalized universe of speech. This raises the question of the communication and the sharing of information between the different groups. Parents who didn't live the relapse of their children and the caregivers gave prepsychotic or psychotic symptoms of relapse. Conversely, parents who had lived relapse(s) of their children gave nonspecific and very personalized signs of relapse (e.g., "When she relapses, our daughter eats much more cheese than usually"). The patients with a low level of awareness of his/her problem were able to describe early signs of relapse. They described mood and sleep disturbances. This is an unexpected result and calls for a debate on the need or not to have good insight in order to follow a psychoeducation program. This study insists on the complementarity of different conceptions of all persons involved in schizophrenic relapse in order to identify as accurately as possible the "relapse signature" of patients. According to us, and in order to promote suitable subjective data to increase insight, compliance and therapeutic alliance, psychoeducation programs should rely on these personal criteria rather than propose systematic programs. Then the relapse signature could be the first step to the appropriation of the course of illness and control of psychotic symptoms by schizophrenic patients. Copyright © 2010 L'Encéphale, Paris.

Upper respiratory infections were reported to trigger multiple sclerosis relapses. A relationship between picornavirus infections and MS relapses was recently reported. To evaluate whether human rhinovirus is associated with multiple sclerosis relapses and whether any particular strain is predominant. Nasopharyngeal fluid was aspirated from 36 multiple sclerosis patients at pre-defined critical time points. Reverse-transcriptase-PCR was performed to detect human rhinovirus-RNA. Positive amplicons were sequenced. We found that rhinovirus RNA was present in 17/40 (43%) of specimens obtained at the onset of a URTI in 19 patients, in 1/21 specimens during convalescence after URTI in 14 patients, in 0/6 specimens obtained in 5 patients on average a week after the onset of an "at risk" relapse, occurring within a window in time from one week before to three weeks after an infection, and in 0/17 specimens obtained after the onset of a "not at risk" relapse not associated with any infection in 12 patients. Fifteen specimens from healthy control persons not associated with URTI were negative. The frequency of HRV presence in URTI was similar to that reported for community infections. Eight amplicons from patients represented 5 different HRV strains. We were unable to reproduce previous findings of association between HRV infections and multiple sclerosis relapses. HRV was not present in nasopharyngeal aspirates obtained during "at risk" or "not at risk" relapses. Sequencing of HRV obtained from patients during URTI did not reveal any strain with predominance in multiple sclerosis.

Opioid dependence relapse is a complex and multidimensional problem, and lack of spiritual well-being is a major concern in opioid addicts. This study was conducted to determine spiritual well-being and factors associated with relapse among opioid addicts. This cross-sectional study was conducted from April 2015 to September 2015. According to purposive sampling, 312 eligible addicted patients were enrolled in the study. The patients had at least an attempt of detoxification in the past six months and referred to an outpatient detoxification clinic in Shahrekord (Southwest, Iran). They completed Paloutzian and Ellison's Spiritual Well-being Scale. A researcher-developed questionnaire consisting of demographic characteristics and 20 questions about associated factors with relapse was administered. Data were analysed by version 16.0 (SPSS Inc.,Chicago, IL) using one-way ANOVA, Pearson's correlation test, chi-square, Friedman test, and student's t-test. The most important factors associated with opioid dependence relapse consist of relation with an addict friend, unemployment, living expenses, family conflicts, and somatic pain. In the present study, 157 patients had never experienced relapse while the mean of relapse in the rest participants was (3.25±1.53) times. Furthermore, the addicted patients with relapse had significantly lower scores of spiritual well-being and its subscales compared with non-relapse patients (p<0.001). The findings of the present study indicate the necessity of paying attention to spiritual well-being, family and economical, personal, and occupational factors as crucial factors in opiate addiction relapse.

The maxillary horizontal relapse following Le Fort I advancement has been estimated to be 10% to 50%. This retrospective review examines the direct association between the amounts of maxillary advancement and relapse. We hypothesize that the greater the advancement, the greater the relapse amount. Patients with class III skeletal malocclusion underwent maxillary advancement with either a Le Fort I or a Le Fort I with simultaneous mandibular setback (bimaxillary surgery) from 2008 to 2015. Patients were assessed for a history of cleft lip or cleft palate. Patients with known syndromes were excluded. Cephalometric analysis was performed to compare surgical and postsurgical changes. Of 136 patients, 47.1% were males and 61.8% had a history of cleft. The mean surgery age was 18.9 (13.8-23) years and 53.7% underwent a bimaxillary procedure. A representative subgroup of 35 patients had preoperative, immediate postoperative, and an average of 1-year postoperative lateral cephalograms taken. The mean maxillary advancement was 6.3 mm and the horizontal relapse was 1.8 mm, indicating a 28.6% relapse. A history of cleft and amount of maxillary advancement were directly correlated, whereas bone grafting of the maxillary osteotomy sites was inversely correlated with the amount of relapse ( P < .05). Our data suggest positive correlation between amount of maxillary advancement and horizontal relapse as well as a positive correlation between history of cleft and horizontal relapse. Bone grafting of the maxillary osteotomy sites has a protective effect on the relapse.

Pemphigus vulgaris (PV) is characterized by multiple relapses, occurring especially in patients on minimal therapy or off therapy. To identify immunologic predictors (anti-desmoglein [Dsg] 1 and 3 antibodies; direct immunofluorescence [DIF]) for relapse in PV patients. Eighty-nine patients in complete clinical remission for at least 6 months and receiving less than or equal to 10 mg prednisolone daily and no immunosuppressive drugs were evaluated using DIF (n=89) and Dsg ELISA (n=46). They were followed until relapse or for at least 18 months. DIF was positive in 44 of 89 patients (49.5%); anti-Dsg 3 antibodies were detected in 18 of 46 patients (39.1%) and anti-Dsg 1 antibodies were detected in 4 of 46 patients (8.7%). Relapse occurred in 38 patients (42.7%). Mean relapse-free time was significantly shorter in anti-Dsg 3-positive patients compared to anti-Dsg 3- negative patients (P = .015) and in DIF-positive patients compared to DIF-negative patients (P = .047), but not in anti-Dsg 1- positive patients compared to anti-Dsg 1-negative patients (P = .501). Sensitivity and predictive values of neither of these tests were high. Small number of anti-Dsg 1-positive patients and use of conventional ELISA. Positive anti-Dsg 3 ELISA and, to a lesser degree, positive DIF are predictors of relapse in PV patients in clinical remission. Decision on discontinuing treatment should be based on the results of these tests as well as on clinical findings. Copyright © 2015 American Academy of Dermatology, Inc. Published by Elsevier Inc.

Introduction Ketamine has shown rapid though short-lived antidepressant effects. The possibility of concerning neurobiological changes following repeated exposure to the drug motivate the development of strategies that obviate or minimize the need for longer-term treatment with ketamine. In this open-label trial, we investigated whether cognitive behavioral therapy (CBT) can sustain or extend ketamine's antidepressant effects. Methods Patients who were pursuing ketamine infusion therapy for treatment-resistant depression (TRD) were invited to participate in the study. If enrolled, the subjects initiated a 12-session, 10-week course of CBT concurrently with a short 4-treatment, 2-week course of intravenous ketamine (0.5mg/kg infused over 40 mins) provided under a standardized clinical protocol. Results Sixteen participants initiated the protocol, with 8 (50%) attaining a response to the ketamine and 7 (43.8%) achieving remission during the first two weeks of protocol. Among ketamine responders, the relapse rate at the end of the CBT course (8 weeks following the last ketamine exposure) was 25% (2/8). On longer-term follow up, 5 of 8 subjects eventually relapsed, the median time-to-relapse being 12 weeks following ketamine exposure. Among ketamine remitters, 3 of 7 retained remission until at least 4 weeks following the last ketamine exposure, with 2 retaining remission through 8 weeks following ketamine exposure. Ketamine non-responders did not appear to benefit from CBT. Conclusions CBT may sustain the antidepressant effects of ketamine in TRD. Well-powered randomized controlled trials are warranted to further investigate this treatment combination as a way to sustain ketamine's antidepressant effects. PMID:28490030

The purpose of this study was to examine relationships between genetic markers of central serotonin (5-HT) and dopamine function, and risk for post-treatment relapse, in a sample of alcohol-dependent patients. The study included 154 patients from addiction treatment programs in Poland, who met DSM-IV criteria for alcohol dependence. After assessing demographics, severity of alcohol use, suicidality, impulsivity, depression, hopelessness, and severity of alcohol use at baseline, patients were followed for approximately 1 year to evaluate treatment outcomes. Genetic polymorphisms in several genes (TPH2, SLC6A4, HTR1A, HTR2A, COMT, and BDNF) were tested as predictors of relapse (defined as any drinking during follow-up) while controlling for baseline measures. Of 154 eligible patients, 123 (80%) completed follow-up and 48% (n = 59) of these individuals relapsed. Patients with the Val allele in the Val66Met BDNF polymorphism and the Met allele in the Val158Met COMT polymorphism were more likely to relapse. Only the BDNF Val/Val genotype predicted post-treatment relapse [odds ratio (OR) = 2.62; p = 0.019], and time to relapse (OR = 2.57; p = 0.002), after adjusting for baseline measures and other significant genetic markers. When the analysis was restricted to patients with a family history of alcohol dependence (n = 73), the associations between the BDNF Val/Val genotype and relapse (OR = 5.76, p = 0.0045) and time to relapse (hazard ratio = 4.93, p = 0.001) were even stronger. The Val66Met BDNF gene polymorphism was associated with a higher risk and earlier occurrence of relapse among patients treated for alcohol dependence. The study suggests a relationship between genetic markers and treatment outcomes in alcohol dependence. Because a large number of statistical tests were conducted for this study and the literature on genetics and relapse is so novel, the results should be considered as hypothesis generating and need to be replicated in independent studies.

Ulcerative colitis (UC) is characterized by chronic intestinal inflammation. Patients with UC have repeated remission and relapse. Clinical biomarkers that can predict relapse in UC patients in remission have not been identified. To facilitate the prediction of relapse of UC, we investigated the potential of novel multivariate indexes using statistical modeling of plasma free amino acid (PFAA) concentrations. We measured fasting PFAA concentrations in 369 UC patients in clinical remission, and 355 were observed prospectively for up to 1 year. Relapse rate within 1 year was 23% (82 of 355 patients). The age- and gender-adjusted hazard ratio for the lowest quartile compared with the highest quartile of plasma histidine concentration was 2.55 (95% confidence interval: 1.41–4.62; p = 0.0020 (log-rank), p for trend = 0.0005). We demonstrated that plasma amino acid profiles in UC patients in clinical remission can predict the risk of relapse within 1 year. Decreased histidine level in PFAAs was associated with increased risk of relapse. Metabolomics could be promising for the establishment of a non-invasive predictive marker in inflammatory bowel disease. PMID:26474176

Ability to predict freedom from heartburn relapse during maintenance therapy for healed reflux oesophagitis may facilitate optimal treatment choices for individual patients. To determine factors predicting freedom from heartburn relapse during maintenance proton pump inhibitor therapy in patients with healed reflux oesophagitis. This post-hoc analysis used data from the maintenance phase of the EXPO study (AstraZeneca study code: SH-NEG-0008); 2766 patients with healed reflux oesophagitis and resolved heartburn received once-daily esomeprazole 20 mg or pantoprazole 20 mg for 6 months. Multiple logistic regression analysis determined factors associated with freedom from heartburn relapse. Heartburn relapse rates were lower with esomeprazole than pantoprazole in all subgroups analysed. Esomeprazole treatment was the factor most strongly associated with freedom from heartburn relapse (odds ratio 2.08; P < 0.0001). Other factors significantly associated with freedom from heartburn relapse were Helicobacter pylori infection, greater age, non-obesity, absence of epigastric pain at baseline, pre-treatment nonsevere heartburn and GERD symptom duration < or =5 years. Several factors predict freedom from heartburn relapse during maintenance proton pump inhibitor therapy for healed reflux oesophagitis, the strongest being choice of proton pump inhibitor. These findings outline the importance of optimizing acid control and identifying predictors of relapse for effective long-term symptom management in reflux oesophagitis patients.

Relapse of tuberculosis (TB) is known to be as one of the major risk factors for resistant TB. The aim of this study is to focus on clinical, radiological and bacteriological features of patients with pulmonary TB relapse. We performed a retrospective survey in the respiratory department of the teaching hospital La Rabta in Tunis between January 2000 and December 2014. Data of patients with a pulmonary TB relapse were analyzed. During the study period, among 1250 patients hospitalized for pulmonary TB, 44 had a TB relapse. The TB relapse rate was estimated to be at 3.5%. The average age was 43.95±16.7 years. Sex ratio was 5,2. Eighty one percent of patients were current smokers. Alcoholism was found in 40.9% of cases. The mean time to relapse was 6.37±3.7 years. The radiological lesions were moderately extended at least in 54.6% of cases. A resistant TB was found in 33% of cases (mono-resistance: 33.3%, multi-drug resistance (TB-MR): 11,1%, poly-resistance: 55.5%). The most incriminated drugs were isoniazid, rifampicin and pyrazinamide. One patient received TB-MR treatment regimen for 18 months. In the other cases, the duration of treatment was prolonged. Recovery was obtained in 72.7% of cases, two patients died and 22.7% of patients were lost to follow up. In Tunisia, TB relapse usually affects young male patients who are often alcoholic and smokers. Resistant TB is frequent among these patients. These findings lead us to emphasize the need of rapid diagnosis tools and adapted treatment regimen in these patients. Copyright © 2018 Elsevier Masson SAS. All rights reserved.

The incidence of recurrent tinea infections after oral terbinafine therapy is on the rise. This study aims to identify the appearance of incomplete cure and relapse after 2-week oral terbinafine therapy in tinea corporis and/or tinea cruris. A total of 100 consecutive patients clinically and mycologically diagnosed to have tinea corporis and/or tinea cruris were included in the study. The enrolled patients were administered oral terbinafine 250 mg once daily for 2 weeks. All clinically cured patients were then followed up for 12 weeks to look for any relapse/cure. The common dermatophytes grown on culture were Trichophyton rubrum and Trichophyton tonsurans in 55% and 20% patients, respectively. At the end of 2-week oral terbinafine therapy, 30% patients showed a persistent disease on clinical examination while 35% patients showed a persistent positive fungal culture (persisters) at this time. These culture positive patients included all the clinically positive cases. Rest of the patients (65/100) demonstrated both clinical and mycological cure at this time (cured). Over the 12-week follow-up, clinical relapse was seen in 22 more patients (relapse) among those who had shown clinical and mycological cure at the end of terbinafine therapy. Thus, only 43% patients could achieve a long-term clinical and mycological cure after 2 weeks of oral terbinafine treatment. Majority of the relapses (16/22) were seen after 8 weeks of completion of treatment. There was no statistically significant difference in the body surface area involvement or the causative organism involved between the cured, persister, or relapse groups. Incomplete mycological cure as well as relapse is very common after standard (2-week) terbinafine therapy in our patients of tinea cruris/corporis.

Thrombomodulin (TM) on the cell-surface of cerebrovascular endothelial cells (CECs) is released into blood upon CEC damage. TM promotes activation of protein C (APC), an anticoagulant, anti-inflammatory, neuroprotective molecule that protects CECs and impedes inflammatory cell migration across the blood-brain barrier (BBB). Multiple sclerosis (MS) is associated with CEC damage and BBB dysfunction. We evaluated soluble TM (sTM) levels as a biomarker of BBB integrity and whether glatiramer acetate (GA) influenced sTM levels in MS patients. sTM levels quantified by 2-site ELISA from sera of healthy controls and systemic lupus erythematosus (SLE) patients (CEC-damage positive control) were compared with levels from patients with relapsing-remitting (RRMS) or secondary-progressive MS (SPMS), stratified as: RRMS/GA/no relapse, RRMS/GA/in relapse, RRMS no GA/no relapse, RRMS/no GA/in relapse; and SPMS/no GA. Additionally, soluble endothelial protein C receptor (sEPCR) levels were assessed in the non-stratified MS group, SLE patients, and controls. sTM levels were highest in RRMS patients taking GA with or without relapse, followed in decreasing order by SLE, RRMS/no GA/in relapse, SPMS, RRMS/no GA/no relapse, healthy controls. sEPCR levels were highest in MS patients, then SLE, then controls. sTM may be a useful biomarker of BBB integrity in RRMS patients. Further evaluation of sEPCR is needed. The finding that the highest sTM levels were in RRMS patients taking GA is interesting and warrants further investigation. Published by Elsevier B.V.

Data are limited regarding outcomes of patients treated for relapsed hepatoblastoma. We reviewed enrollment patterns and outcomes of patients with hepatoblastoma on Children's Oncology Group (COG) phase I/II studies. The medical literature was searched for reports of COG phase I/II studies using PUBMED as well as an inventory from the COG publications office searching manuscripts published from 2000 to 2014. Seventy-one patients with relapsed hepatoblastoma were enrolled on 23 separate COG phase I/II studies. Four studies collected α-fetoprotein (AFP) data, but none utilized AFP decline in assessing response. Most studies enrolled few patients with relapsed hepatoblastoma: 7 studies enrolled 1 patient, and another 7 studies enrolled 2 patients each. Only 9 studies enrolled 3 or more patients with relapsed hepatoblastoma. Four responses were reported. Dedicated strata and/or focus on 1 or 2 studies with compelling biological or clinical rationale for hepatoblastoma may improve accrual (and statistical significance of response data) of patients with relapsed hepatoblastoma. Prospective study of AFP decline versus RECIST response could help determine the optimal method of assessing response to identify potentially beneficial treatments in hepatoblastoma.

To report a case of early-decompensated liver cirrhosis secondary to discontinuation of penicillamine therapy in a patient with Wilson's disease. A 33-year-old Chinese female patient was diagnosed with Wilson's disease, for which penicillamine 250 mg p.o. once daily was prescribed. However, the patient developed intolerance and penicillamine was discontinued without alternative treatment. Five months later, she developed decompensated liver cirrhosis with hepatic encephalopathy. Eventually, the patient died because of the complications of sepsis and decompensated liver failure. Chelating agent is the mainstay of treatment in Wilson's disease, which is an inherited disorder of hepatic copper metabolism. Therapy must be instituted and continued for life once diagnosis is confirmed. Interruption of therapy can be fatal or cause irreversible relapse. Penicillamine given orally is the chelating agent of first choice. However, its unfavourable side-effects profile leads to discontinuation of therapy in 20-30% of patients. In most case reports, cessation of penicillamine without replacement treatment causes rapid progression to fulminant hepatitis, which is fatal unless liver transplantation is performed. In this, we highlight a case of discontinuation of penicillamine in a patient with Wilson's disease without substitution with alternative regimen. This was caused by unavailability of the alternative agents such as trientine in our country. Consequently, the patient progressed to decompensated liver cirrhosis with encephalopathy and eventually passed-away within 5 months. One recent study supports a combination of trientine and zinc in treating patient with decompensated liver cirrhosis. This combination is capable of reversing liver failure and prevents the need of liver transplantation. Both trientine and zinc are not registered in Malaysia. Therefore, liver transplantation was probably the only treatment option for this patient. Hence, non-availability of orphan drugs in clinical practice is certainly a subject of serious concern. Systems for better management of patients with rare diseases need to be instituted by all the institutions concerned.

Effects of music therapy on drug avoidance self-efficacy in patients on a detoxification unit: a three-group randomized effectiveness study.

PubMed

Silverman, Michael J

2014-01-01

Self-efficacy is a component of Bandura's social cognitive theory and can lead to abstinence and a reduction of relapse potential for people who have substance abuse disorders. To date, no music therapy researcher has utilized this theoretical model to address abstinence and reduce the likelihood of relapse in people who have addictions. The purpose of this study was to determine the effects of music therapy on drug avoidance self-efficacy in a randomized three-group wait-list control design with patients on a detoxification unit. Participants (N = 131) were cluster randomized to one of three single-session conditions: music therapy, verbal therapy, or wait-list control. Music therapy participants received a group lyric analysis intervention, verbal therapy participants received a group talk therapy session, and wait-list control participants eventually received a group recreational music therapy intervention. Although there was no significant between-group difference in drug avoidance self-efficacy, participants in the music therapy condition tended to have the highest mean drug avoidance self-efficacy scores. Posttest written comments supported the use of both music therapy and verbal therapy sessions. Two music therapy participants specifically noted that their initial skepticism had dissipated after receiving music therapy. Despite a lack of significant differences, the theoretical support of self-efficacy for substance abuse rehabilitation suggests that this may be an area of continued clinical focus and empirical investigation. Clinical anecdotes, limitations of the study, and suggestions for future research are provided.

We investigated the rate of relapse of hepatitis B virus (HBV) infection after entecavir therapy for chronic hepatitis B and the association between level of hepatitis B surface antigen (HBsAg) and relapse. In a retrospective study, we analyzed data from 252 patients with chronic HBV infection who were treated with entecavir and met the Asian Pacific Association for the Study of the Liver treatment stopping rules (mean time, 164 ± 45 weeks) from January 2007 through June 2011 in Taiwan. Eighty-three were hepatitis B e antigen (HBeAg)-positive, and 169 were HBeAg-negative. Patients had regular post-treatment follow-up examinations for at least 12 months. Virologic relapse was defined on the basis of serum HBV DNA >2000 IU/mL after entecavir therapy. Clinical relapse was defined as a level of alanine aminotransferase > 2-fold the upper limit of normal and HBV DNA > 2000 IU/mL. Two years after therapy ended, 42% of HBeAg-positive patients had a virologic relapse, and 37.6% had a clinical relapse; 3 years after therapy ended, these rates were 64.3% and 51.6% for HBeAg-negative patients, respectively. On the basis of Cox regression analysis, factors independently associated with virologic and clinical relapse included old age, HBV genotype C, and higher baseline levels of HBsAg for HBeAg-positive patients and old age and higher end-of-treatment levels of HBsAg for HBeAg-negative patients. In HBeAg-positive patients, risk of HBV relapse increased with age ≥ 40 years and HBsAg level ≥ 1000 IU/mL at baseline (P < .001). In HBeAg-negative patients, the combination of age (< 55 years) and HBsAg level (< 150 IU/mL) at the end of treatment was associated with a lower rate of virologic relapse (4.5% of HBeAg-negative patients had viral relapse at year 3). The decrease in level of HBsAg from month 12 of treatment until the end of treatment was greater in patients who did lose HBsAg after entecavir therapy compared with those who did not. The combination of age and level of HBsAg is associated with relapse of HBV infection after treatment with entecavir. HBsAg levels might be used to guide the timing of cessation of entecavir treatment in patients with chronic HBV infection. Copyright © 2015 AGA Institute. Published by Elsevier Inc.

Natalizumab is an effective therapy in relapsing-remitting multiple sclerosis (RRMS), as it reduces lymphocyte transmigration through the blood-brain barrier (BBB) and induces lymphocytosis. To analyse natalizumab-induced lymphocytosis (NIL) as a biomarker of drug efficacy. We enrolled 50 relapsing-remitting (RR) and progressive-relapsing (PR) natalizumab-treated patients who had received at least 16 infusions and had been tested for lymphocyte count 24 hours before each administration. Clinical, MRI and hematological data were collected. Patients were divided into responders and sub-optimal responders according to the experience of at least one clinical and/or instrumental relapse during the treatment. In 15 (30%) patients, an instrumental/clinical (14) or only instrumental (one) relapse occurred. We found a statistically significant difference in the mean percentage of the lymphocytes between the two groups over the first ten administrations (p=0.04). The comparison between the time-to-relapse in the groups with high and low levels of lymphocytes showed that the group with a low NIL had a greater risk of relapse (p=0.03). We suggest that NIL could be a biomarker of therapeutic efficacy in patients with RRMS treated with natalizumab, and that the risk of relapse may be higher in patients with a lower-than-expected NIL. © The Author(s), 2015.

In this prospective, multicenter, phase 2 study, 64 patients with relapsed or relapsed and refractory multiple myeloma (MM) received up to 8 21-day cycles of bortezomib 1.0 mg/m2 (days 1, 4, 8, and 11), lenalidomide 15 mg/day (days 1-14), and dexamethasone 40/20 mg/day (cycles 1-4) and 20/10 mg/day (cycles 5-8) (days of/after bortezomib dosing). Responding patients could receive maintenance therapy. Median age was 65 years; 66% were male, 58% had relapsed and 42% had relapsed and refractory MM, and 53%, 75%, and 6% had received prior bortezomib, thalidomide, and lenalidomide, respectively. Forty-eight of 64 patients (75%; 90% confidence interval, 65-84) were alive without progressive disease at 6 months (primary end point). The rate of partial response or better was 64%; median duration of response was 8.7 months. Median progression-free and overall survivals were 9.5 and 30 months, respectively (median follow-up: 44 months). Common treatment-related toxicities included sensory neuropathy (53%), fatigue (50%), and neutropenia (42%); common grade 3/4 treatment-related toxicities included neutropenia (30%), thrombocytopenia (22%), and lymphopenia (11%). Grade 3 motor neuropathy was reported in 2 patients. Lenalidomide-bortezomib-dexamethasone appears effective and tolerable in patients with relapsed or relapsed and refractory MM, demonstrating substantial activity among patients with diverse prior therapies and adverse prognostic characteristics. This trial is registered with www.clinicaltrials.gov as #NCT00378209. PMID:24429336

Relapsed or refractory pediatric acute lymphoblastic leukemia: current and emerging treatments.

PubMed

Relapsed acute lymphoblastic leukemia (ALL) represents a major cause of morbidity and mortality in pediatrics. With contemporary chemotherapy, >85% of patients with newly diagnosed ALL survive. Unfortunately, 20% of these patients will relapse and for these children, outcomes remain poor despite our best known chemotherapy protocols. Most of these children will achieve a second complete remission, but maintaining this remission remains difficult. Because relapsed ALL is such a significant cause of morbidity and mortality, it is the focus of much research interest. Efforts have been made and continue to focus on understanding the underlying biology that drives relapse. The role of hematopoietic stem cell transplantation in relapsed ALL remains unclear, but many clinicians still favor this for high-risk patients given the poor prognosis with current chemotherapy alone. It is important to use new drugs with little cross-resistance in the treatment of relapsed ALL. New classes of agents are currently being studied. We also discuss prognostic factors and the biology of relapsed ALL.

While relapses following clinical cure of American cutaneous leishmaniasis are frequent, no test has been described until now to predict such relapses. A cohort of 318 American cutaneous leishmaniasis patients was followed up for two years after treatment with meglumine antimoniate, during which time 32 relapses occurred, 30 in the first year and two in the second (accumulated risk: 10.5%). No association was found between these relapses and the parasite-specific antibody response before and after treatment, or between the relapses and stratification by sociodemographic and clinical characteristics. However when Leishmania was used as antigen, patients with a negative skin test at the time of diagnosis presented a 3.4-fold higher risk (hazard risk = 3.4; 95% confidence interval, 1.7-7.0) of American cutaneous leishmaniasis relapse, compared with patients with a positive response. This result shows that the skin test can be a predictor of American cutaneous leishmaniasis relapse after treatment. PMID:10994280

Whole Neuraxis Irradiation to Address Central Nervous System Relapse in High-Risk Neuroblastoma

DOE Office of Scientific and Technical Information (OSTI.GOV)

Croog, Victoria J., E-mail: vcroog@sibley.or; Kramer, Kim; Cheung, Nai-Kong V.

Background: As systemic control of high-risk neuroblastoma (NB) has improved, relapse in the central nervous system (CNS) is an increasingly recognized entity that carries a grim prognosis. This study describes the use of craniospinal irradiation (CSI) for CNS relapse and compares outcomes to patients who received focal radiotherapy (RT). Methods: A retrospective query identified 29 children with NB treated at Memorial Sloan-Kettering Cancer Center since 1987 who received RT for CNS relapse. At CNS relapse, 16 patients received CSI (median dose, 2160cGy), and 13 received focal RT. Of those who underwent CSI, 14 (88%) received intra-Ommaya (IO) radioimmunotherapy (RIT); onemore » patient in the non-CSI cohort received IO-RIT. Results: Patient characteristics were similar between the groups. Time to CNS relapse was 20 and 17 months for the CSI and non-CSI cohorts, respectively. At a median follow-up of 28 months, 12 patients (75%) in the CSI group are alive without CNS disease, including two patients with isolated skeletal relapse. Another patient is alive without disease after a brain relapse was retreated with RT. Three patients died-one with no NB at autopsy, one of CNS disease, and one of systemic disease. The two patients who died of NB did not receive IO-RIT. All 13 patients in the non-CSI cohort died at a median of 8.8 months. Conclusions: Low-dose CSI together with IO-RIT provides durable CNS remissions and improved survival compared with focal RT and conventional therapies. Further evaluation of long-term NB survivors after CSI is warranted to determine the treatment consequences for this cohort.« less

Objective: To estimate sample sizes for pediatric multiple sclerosis (MS) trials using new T2 lesion count, annualized relapse rate (ARR), and time to first relapse (TTFR) endpoints. Methods: Poisson and negative binomial models were fit to new T2 lesion and relapse count data, and negative binomial time-to-event and exponential models were fit to TTFR data of 42 children with MS enrolled in a national prospective cohort study. Simulations were performed by resampling from the best-fitting model of new T2 lesion count, number of relapses, or TTFR, under various assumptions of the effect size, trial duration, and model parameters. Results: Assuming a 50% reduction in new T2 lesions over 6 months, 90 patients/arm are required, whereas 165 patients/arm are required for a 40% treatment effect. Sample sizes for 2-year trials using relapse-related endpoints are lower than that for 1-year trials. For 2-year trials and a conservative assumption of overdispersion (ϑ), sample sizes range from 70 patients/arm (using ARR) to 105 patients/arm (TTFR) for a 50% reduction in relapses, and 230 patients/arm (ARR) to 365 patients/arm (TTFR) for a 30% relapse reduction. Assuming a less conservative ϑ, 2-year trials using ARR require 45 patients/arm (60 patients/arm for TTFR) for a 50% reduction in relapses and 145 patients/arm (200 patients/arm for TTFR) for a 30% reduction. Conclusion: Six-month phase II trials using new T2 lesion count as an endpoint are feasible in the pediatric MS population; however, trials powered on ARR or TTFR will need to be 2 years in duration and will require multicentered collaboration.

Most patients with acute myeloid leukemia (AML) and t(8;21) or inv(16) have a good prognosis with current anthracycline- and cytarabine-based protocols. Tandem analysis with flow cytometry (FC) and real-time RT-PCR (RQ-PCR) was applied to 55 patients, 28 harboring a t(8;21) and 27 an inv(16), including one case with a novel CBFbeta/MYH11 transcript. A total of 31% (n=17) of CR patients relapsed: seven with t(8;21) and 10 with inv(16). The mean amount of minimal residual disease (MRD) detected by FC in relapsed and nonrelapsed patients was markedly different: 0.3 vs 0.08% (P=0.002) at the end of treatment. The mean number of fusion transcript copies/ ABL x 10(4) also differed between relapsed and non-relapsed patients: 2385 vs 122 (P=0.001) after induction, 56 vs 7.6 after intensification (P=0.0001) and 75 vs 3.3 (P=0.0001) at the end of chemotherapy. Relapses were more common in patients with FC MRD level >0.1% at the end of treatment than in patients with < or = 0.1%: cumulative incidence of relapse (CIR) was 67 and 21% (P=0.03), respectively. Likewise, using RQ-PCR, a cutoff level of >10 copies at the end of treatment correlated with a high risk of relapse: CIR was 75% for patients with RQ-PCR >10 compared to 21% for patients with RQ-PCR levels < or = 10 (P=0.04). Combined use of FC and RQ-PCR may improve MRD detection, and provide useful clinical information on relapse kinetics in AML patients.

Methadone maintenance treatment (MMT) is recognized as one of the most effective treatments for heroin addiction but its effect is dimmed by the high incidence of heroin relapse. However, underlying neurobiology mechanism of heroin relapse under MMT is still largely unknown. Here, we took advantage of a resting-state fMRI technique by analysis of regional homogeneity (ReHo), and tried to explore the difference of brain function between heroin relapsers and non-relapsers in MMT. Forty MMT patients were included and received a 12-month follow-up. All patients were given baseline resting-state fMRI scans by using a 3.0 T GE Signa Excite HD whole-body MRI system. Monthly self-report and urine test were used to assess heroin relapse or non-relapse. Subjective craving was measured with visual analog scale. The correlation between ReHo and the degree of heroin relapse was analyzed. Compared with the non-relapsers, ReHo values were increased in the bilateral medial orbitofrontal cortex, right caudate, and right cerebellum of the heroin relapsers while those in the left parahippocampal gyrus, left middle temporal gyrus, right lingual gyrus, and precuneus were decreased in heroin relapsers. Importantly, altered ReHo in the right caudate were positively correlated with heroin relapse rates or subjective craving response. Using the resting-state fMRI technique by analysis of ReHo, we provided the first resting-state fMRI evidence that right caudate may serve as a potential biomarker for heroin relapse prediction and also as a promising target for reducing relapse risk.

Early death (ED) remains the most critical issue in the current care of patients with acute promyelocytic leukemia (APL). Very limited data are available regarding ED in patients with relapsed APL. In this retrospective study, 285 de novo and 79 relapsed patients were included. All patients received single-agent arsenic trioxide as induction therapy. The differences in baseline clinical features, incidence, causes, and prognostic factors of ED were compared between the two patient cohorts. The relapse cohort exhibited a better overall condition than the de novo cohort upon hospital admission. The ED rate in the relapsed patients (24.1%) was somewhat higher than that in the de novo patients (17.9%), although the difference was not significant (P = 0.219). For both cohorts, hemorrhage was the main cause of ED, followed by differentiation syndrome, infection, and other causes. Increased serum creatinine level, older age, male sex, white blood cell (WBC) count > 10 × 10 9 /L, and fibrinogen < 1 g/L were independently risk factors for ED in the de novo patients, whereas WBC count > 10 × 10 9 /L, elevated serum uric acid level, and D-dimer > 4 mg/L were independent risk factors for ED in the relapsed patients. These data furnish clinically relevant information that might be useful for designing more appropriate risk-adapted treatment protocols aimed at reducing ED rate in patients with relapsed APL.

Protective effect of CMV reactivation on relapse after allogeneic hematopoietic cell transplantation in AML patients is influenced by their conditioning regimen

Cytomegalovirus (CMV) reactivation after allogeneic hematopoietic cell transplant (allo-HCT) has been associated with reduced risk of relapse in patients with acute myeloid leukemia (AML). However the influence of the conditioning regimen on this protective effect of CMV reactivation after allo-HCT is relatively unexplored. To address this, we evaluated the risk of relapse in 264 AML patients who received T cell replete, 6/6 HLA matched sibling or 10/10 HLA matched unrelated donor transplantation at a single institution between 2006 and 2011. Out of these 264 patients, 206 received myeloablative (MA) and 58 received reduced intensity conditioning (RIC) regimens. CMV reactivation was observed in 88 patients with MA conditioning and 37 patients with RIC. At a median follow up of 299 days, CMV reactivation was associated with significantly lower risk of relapse in patients who received MA conditioning both in univariate (P= .01) and multivariate analyses (hazard ratio of 0.5246, P= .006), however CMV reactivation did not significantly affect the risk of relapse in our RIC cohort. These results confirm the protective effect of CMV reactivation on relapse in AML patients after allo-HCT reported by previous studies, however they suggest that this protective effect of CMV reactivation on relapse is influenced by the conditioning regimen used with the transplant.

To evaluate if WT1 expression may predict relapse after allo-SCT, we analyzed WT1 levels on peripheral blood (PB) and bone marrow (BM) before and after allo-SCT in 24 AML patients with WT1 overexpression at diagnosis. Five copies of WT1/ABL × 104 from PB were identified as the threshold value that correlated with relapse after allo-SCT. The same correlation was not identified when WT1 expression was assessed from bone marrow (BM). Eight out of 11 (73%) patients with a pre-allo-SCT PB-WT1 ≥ 5 and 4/13 (31%) patients with a pre-allo-SCT PB-WT1 < 5 relapsed, respectively (P = 0.04). The incidence of relapse was higher in patients with PB-WT1 ≥ 5 measured after allo-SCT, at the 3rd (56% versus 38%; P = 0.43) and at the 6th month (71% versus 20%; P = 0.03). Patients with pretransplant PB-WT1 < 5 had significantly better 2-year OS and LFS than patients with a PB-WT1 ≥ 5 (81% versus 0% and 63% versus 20%) (P = 0.02). Our data suggest the usefulness of WT1 monitoring from PB to predict the relapse in allotransplanted AML patients and to modulate the intensity of conditioning and/or the posttransplant immunosuppression in an attempt to reduce the posttransplant relapse risk.

The aim of this study was to determine whether current guidance or consensus regarding continuation pharmacotherapy after successful electroconvulsive therapy (ECT) was being followed by referring clinicians in West Sussex, United Kingdom. A complete audit cycle examining psychotropic medication after successful ECT for patients with severe depression was performed. Clinical and ECT records (electronic and paper) were reviewed, and relapse rates in the 4 commonly prescribed psychotropic medication groups were compared. The pattern of relapse in the 4 groups was similar for both audits 1 and 2. Taking the 102 patients as a whole, the lowest relapse rates were recorded for patients taking a combination of an antidepressant and lithium (16% relapsed within 6 months of successful ECT). Patients taking a combination of antipsychotic and antidepressants fared the worst with 75% relapse rate. This was followed by those taking a combination of antidepressant and a mood stabilizer (other than lithium) (69%). Patients taking antidepressant(s) only were associated with a relapse rate of 60%. Audit 2 demonstrated that clinicians did not change their prescribing practices for their patients after successful ECT despite the efforts made in widely disseminating the results of audit 1. In particular, there was no increase in the use of lithium. Not all psychotropic medication prescribing for patients receiving ECT for depression followed available and current guidance or consensus. More needs to be done to understand the reasons for the reluctance to use lithium if relapse rates after ECT are to improve.

The objective of this study is to assess patient preferences for treatment-related benefits and risk of disease relapse in the management of low disease states of psoriatic arthritis (PsA). Focus groups with patients and a literature review were undertaken to determine the characteristics of treatment and symptoms of PsA important to patients. Patient preferences were assessed using a discrete choice experiment which compared hypothetical treatment profiles of the risk and benefits of treatment withdrawal. The risk outcome included increased risk of disease relapse, while benefit outcomes included reduced sickness/nausea from medication and changes in health-related quality of life. Each patient completed 12 choice sets comparing treatment profiles. Preference weights were estimated using a logic regression model, and the maximum acceptable risk in disease relapse for a given improvement in benefit outcomes was elicited. Final sample included 136 patients. Respondents attached the greatest importance to eliminating severe side effects of sickness/nausea and the least importance to a change in risk of relapse. Respondents were willing to accept an increase in the risk of relapse of 32.6 % in order to eliminate the side effects of sickness/nausea. For improvements in health status, the maximum acceptable risk in relapse was comparable to a movement from some to no sickness/nausea. The study suggests that patients in low disease states of PsA are willing to accept greater risks of relapse for improvements in side effects of sickness/nausea and overall health status, with the most important benefit attribute being the elimination of severe sickness or nausea.

The present study was designed to examine the influence of suicidality on relapse in alcohol-dependent patients. Specifically, a lifetime suicide attempt at baseline was used to predict relapse in the year after treatment. Also, the unique contribution of impulsive suicide attempts was examined. A total of 154 patients with alcohol dependence, consecutively admitted to four addiction treatment facilities in Warsaw, Poland participated in the study. Of the 154 eligible patients, 118 (76.6%) completed a standardized follow-up assessment at 12 months. Previous suicide attempts were common in adults treated for alcohol dependence with 43% patients in the present sample reporting an attempt at some point during their lifetime. Additionally, more than 62% of those with a lifetime suicide attempt reported making an impulsive attempt. Lifetime suicide attempts were not associated with post-treatment relapse (chi-square=2.37, d.f.=1, p=0.124). However, impulsive suicide attempts strongly predicted relapse (OR=2.81, 95% CI=1.13-6.95, p=0.026) and time to relapse (OR=2.10, 95% CI=1.18-3.74, p=0.012) even after adjusting for other measures of baseline psychopathology, depression, impulsivity, hopelessness and alcohol use severity. This study is the first to document the relationship between pre-treatment impulsive suicide attempts and higher likelihood of post-treatment relapse in alcohol-dependent patents. Clinicians should routinely conduct an assessment for previous suicide attempts in patients with alcohol use disorders, and when impulsive suicidality is reported, they should recognize the increased risk for relapse and formulate their patients' treatment plans accordingly with the goals of reducing both alcoholic relapse and suicide rates.

Impairment of olfactory threshold is a feature of early and active relapsing remitting multiple sclerosis (RRMS). It predicts inflammatory disease activity and was reported to be transient. However, the timing of onset and resolve of olfactory threshold impairment remains unclear. To prospectively assess the development of olfactory threshold in acute MS relapse over time in comparison to stable MS patients. In a prospective observational design, we measured olfactory threshold by performing the Sniffin' Sticks test (minimum score 0, maximum score 16 reflecting optimal olfactory function) at baseline and after 4, 12 and 24 weeks. We included 30 RRMS patients with acute MS relapse and 30 clinically stable RRMS patients (defined as no relapse within the last 12 months) as a control group. Olfactory threshold was impaired in patients with acute MS relapse at baseline (median difference = -3.5; inter-quartile range [IQR] -4.5- - 2.5; p < 0.001), week 4 (-2.5; IQR -3.0 - -2.0; p < 0.001), week 12 (-1.5; IQR -2.0 - -0.5; p = 0.002) and week 24 (-0.5; IQR -1.0 - 0.0; p = 0.159) compared to stable MS patients. Of note, in relapsing patients in whom disease-modifying treatment was initiated or escalated after relapse, threshold did not differ anymore from stable patients at week 12 (-0.5; IQR -1.0 - 0.5; p = 0.247) and week 24 (0.0; IQR -1.0 - 1.0; p = 0.753). Olfactory threshold impairment seems to be a transient bystander feature of MS relapse. It may be correlated to the level of inflammation within the CNS and might be a useful biomarker in this regard. Copyright © 2018 Elsevier B.V. All rights reserved.

To compare the effectiveness of treatment for ocular toxoplasmosis with pyrimethamine + clindamycin (or sulfadiazine) + a corticoid (Group 1), or azithromycin or a combination of azithromycin with a corticoid or a corticoid alone (Group 2). To determine the relapse rate depending on the treatment approach. A total of 25 patients treated for ocular toxoplasmosis over the last five years (2008-2013) were analyzed. Group 1 comprised 16 patients (3 were excluded) and Group 2 consisted of 6 patients. Visual improvement was more rapid in Group 1 (day 10.7) than in Group 2 (significant improvement on day 29.6). There were 5 cases of relapse in Group 1; in 13 cases, no relapse was noted; all patients in Group 2 relapsed (a total of 13 relapses). Twenty-three patients were positive for specific IgG antibodies. According to our experiences, pyrimethamine + clindamycin (or sulfadiazine) + a corticoid should be the treatment of choice in patients with ocular toxoplasmosis.

The aim of the present work was to evaluate the usefulness of CA-125 normalized in time area under the curve (CA-125 AUC) to signalise epithelial ovarian cancer relapse. Data from a hundred and eleven patients were submitted to two different approaches based on CA-125 AUC increase values to predict patient relapse. In Criterion A total CA-125 AUC normalized in time value (AUC(i)) was compared with the immediately previous one (AUC(i-1)) using the formulae AUC(i) > or = F * AUC(i-1) (several F values were tested) to find the appropriate close related increment associated to patient relapse. In Criterion B total CA-125 AUC normalised in time was calculated and several cut-off values were correlated with patient relapse prediction capacity. In Criterion A the best accuracy was achieved with a factor (F) of 1.25 (increment of 25% from the previous status), while in Criterion B the best accuracies were achieved with cut-offs of 25, 50, 75 and 100 IU/mL. The mean lead time to relapse achieved with Criterion A was 181 days, while with Criterion B they were, respectively, 131, 111, 63 and 11 days. Based on our results we believe that conjugation and sequential application of both criteria in patient relapse detection should be highly advisable. CA-125 AUC rapid burst in asymptomatic patients should be firstly evaluated using Criterion A with a high accuracy (0.85) and with a substantial mean lead time to relapse (181 days). If a negative answer was obtained then Criterion B should performed to confirm the absence of relapse.

Breast cancer is a heterogeneous disease comprising a variety of entities with various genetic backgrounds. Estrogen receptor-positive, human epidermal growth factor receptor 2-negative tumors typically have a favorable outcome; however, some patients eventually relapse, which suggests some heterogeneity within this category. In the present study, we used proteomics and miRNA profiling techniques to characterize a set of 102 either estrogen receptor-positive (ER+)/progesterone receptor-positive (PR+) or triple-negative formalin-fixed, paraffin-embedded breast tumors. Protein expression-based probabilistic graphical models and flux balance analyses revealed that some ER+/PR+ samples had a protein expression profile similar to that of triple-negative samples and had a clinical outcome similar to those with triple-negative disease. This probabilistic graphical model-based classification had prognostic value in patients with luminal A breast cancer. This prognostic information was independent of that provided by standard genomic tests for breast cancer, such as MammaPrint, OncoType Dx and the 8-gene Score.

Purpose/Objectives: Despite recent improvements in outcomes, 40% of children with high-risk neuroblastoma will experience relapse, facing a guarded prognosis for long-term cure. Whether recurrences are at new sites or sites of original disease may guide decision making during initial therapy. Methods and Materials: Eligible patients were retrospectively identified from institutional databases at first metastatic relapse of high-risk neuroblastoma. Included patients had disease involving metaiodobenzylguanidine (MIBG)-avid metastatic sites at diagnosis and first relapse, achieved a complete or partial response with no more than one residual MIBG-avid site before first relapse, and received no total body irradiation or therapy with {sup 131}I-MIBGmore » before first relapse. Anatomically defined metastatic sites were tracked from diagnosis through first relapse to determine tendency of disease to recur at previously involved versus uninvolved sites and to assess whether this pattern was influenced by site irradiation. Results: Of 159 MIBG-avid metastatic sites identified among 43 patients at first relapse, 131 (82.4%) overlapped anatomically with the set of 525 sites present at diagnosis. This distribution was similar for bone sites, but patterns of relapse were more varied for the smaller subset of soft tissue metastases. Among all metastatic sites at diagnosis in our subsequently relapsed patient cohort, only 3 of 19 irradiated sites (15.8%) recurred as compared with 128 of 506 (25.3%) unirradiated sites. Conclusions: Metastatic bone relapse in neuroblastoma usually occurs at anatomic sites of previous disease. Metastatic sites identified at diagnosis that did not receive radiation during frontline therapy appeared to have a higher risk of involvement at first relapse relative to previously irradiated metastatic sites. These observations support the current paradigm of irradiating metastases that persist after induction chemotherapy in high-risk patients. Furthermore, they raise the hypothesis that metastatic sites appearing to clear with induction chemotherapy may also benefit from radiotherapeutic treatment modalities (external beam radiation or {sup 131}I-MIBG)« less

Purpose: To determine the frequency and clinical significance of epidermal growth factor receptor (EGFR) mutations in patients with potentially curable stage III non–small-cell lung cancer (NSCLC) who are eligible for definitive chemoradiotherapy (CRT). Patients and Methods: Between January 2001 and December 2010, we analyzed the EGFR mutational status in consecutive NSCLC patients who were treated by CRT. The response rate, relapse-free survival, 2-year relapse-free rate, initial relapse sites, and overall survival of the patients were investigated. Results: A total of 528 patients received CRT at our hospital during the study period. Of these, 274 were diagnosed as having nonsquamous NSCLC. Sufficientmore » specimens for mutational analyses could be obtained from 198 of these patients. The proportion of patients with EGFR activating mutations was 17%. In addition to the well-known characteristics of patients carrying EGFR mutations (female, adenocarcinoma, and never/light smoker), the proportion of cases with smaller primary lesions (T1/2) was found to be higher in patients with EGFR mutations than in those with wild-type EGFR. Patients with EGFR mutations showed similar response rate, relapse-free survival, and 2-year relapse-free rates as compared to patients with wild-type EGFR. Local relapses as the site of initial relapse occurred significantly less frequently in patients with EGFR mutation (4% vs 21%; P=.045). Patients with EGFR mutations showed longer local control (adjusted hazard ratio 0.49; P=.043). After disease progression, a majority of the patients with EGFR mutations received EGFR tyrosine kinase inhibitors (62%), and these patients showed longer postprogression survival than those with wild-type EGFR. Conclusions: Our study is the first to show radiosensitive biology of EGFR-mutated tumors in definitive CRT with curative intent. This finding could serve as a credible baseline estimate of EGFR-mutated population in stage III nonsquamous NSCLC.« less

Eight of 22 children with newly diagnosed medulloblastoma had asymptomatic spinal cord involvement detected by myelography. Two additional patients had demonstrable spinal cord lesions at the time of relapse in the posterior fossa. Cerebral spinal fluid (CSF) cytology results were inaccurate in predicting cord involvement. Seven patients have relapsed 9 to 69 months from completion of radiotherapy. Three had initial cord involvement and also had subsequent cord involvement at the time of intracranial relapse or afterwards. Frontal lobe involvement as the initial site of relapse occurred in 3 patients. Computerized tomography has been valuable in the early detection of intracranialmore » relapse. Three children are alive and well 10, 18 and 19 months, respectively, from time of relapse. All were retreated with radiotherapy in conjunction with misonidazole and subsequent chemotherapy.« less

Efficacy, end points and eventualities: sumatriptan/naproxen versus butalbital/paracetamol/caffeine in the treatment of migraine.

PubMed

Fox, Anthony W

2012-09-01

Migraine is a widespread, relapsing, remittent syndrome. No animal model predicts whether test medications will be clinically useful. Using a modern, well-controlled, sophisticated study design, Derosier et al. demonstrates not only that a butalbital formulation has modest efficacy as an acute treatment for migraine but also that a sumatriptan-naproxen combination is superior. These conclusions are reached using a variety of internally consistent secondary efficacy end points. The primary end point chosen (highly conservative and fashionable in some academic circles) was a technical failure (and not a negative experimental finding). Migraine is intrinsically pleiomorphic: diverse treatment options help match patient with therapy. This study does not justify blanket bans on (admittedly hazardous) barbiturate therapies, and regulators should not impose end point conservatism to an extent that will stifle further progress.

Perinuclear anti-neutrophil cytoplasmic antibody (p-ANCA) and anti-Saccharomyces cerevisiae antibody (ASCA) have been proposed as markers for diagnosis and for subtyping of inflammatory bowel disease (IBD). The aim of this study was to investigate the association of p-ANCA and ASCA with a 10-year disease outcome in terms of cumulative rate of colectomy and relapse in a population-based European inception cohort of ulcerative colitis (UC) patients. Serum samples from 432 consenting patients were analysed for p-ANCA and ASCA. The results were compared with the cumulative colectomy rate, relapsing disease and total number of relapses. We used multiple regression analyses adjusted for age, sex, residence, disease extent at diagnosis, smoking, familial IBD and drug treatment to study the relationship between serological values and disease course. The relapse rate was higher in the p-ANCA-positive patients: 82% (95% confidence interval [CI] 75-89%) compared with 67% (CI 62-72%, p=0.011) in the p-ANCA-negative patients. The risk of relapsing disease course was higher by a factor of 1.4 (CI 1.1-1.8, p=0.009) for p-ANCA-positive patients than for p-ANCA-negative patients, and the corresponding relative risk (RR) for the total number of relapses was 1.9 (CI 1.7-2.1, p<0.001). In ASCA-positive patients RR for the total number of relapses was 1.8 (CI 1.5-2.1, p<0.001). No significant association with colectomy rate was found for the presence of either p-ANCA or ASCA. UC patients positive for p-ANCA and possibly for ASCA may have a more unfavourable long-term disease outcome in terms of relapse than UC patients without these markers.

Multiple sclerosis (MS) patients discontinuing natalizumab are at risk of rebound of disease activity. In the present multi-center, open-label, non-randomized, prospective, pilot study, we tested whether treatment with glatiramer acetate (GA) is safe and effective after natalizumab in MS patients. The study was performed at academic tertiary medical centers. Forty active relapsing-remitting MS patients who never failed GA therapy and who discontinued natalizumab after 12-18 months of therapy were enrolled. GA was initiated 4 weeks after the last dose of natalizumab. 62.5% of patients were relapse-free 12 months after GA initiation. Annualized relapse rate and time to relapse were significantly lower than before natalizumab. Notably, the frequency of relapses was significantly lower amongst those patients who had experienced ≤2 relapses the year before initiation of natalizumab therapy, compared with patients who had had three or more relapses. No evidence of rebound was observed in magnetic resonance imaging scans. Furthermore, Expanded Disability Status Scale and Multiple Sclerosis Functional Composite were stable in our patients, again suggesting that 12 months of post-natalizumab-GA therapy is not associated with clinical deterioration. Following discontinuation of natalizumab, 12 months of therapy with GA is safe and well tolerated in MS patients. GA can reduce the risk of early reactivation/rebound of disease activity in this setting. © 2012 The Author(s) European Journal of Neurology © 2012 EFNS.

Value of Surveillance Studies for Patients With Stage I to II Diffuse Large B-Cell Lymphoma in the Rituximab Era

Background: The role of surveillance studies in limited-stage diffuse large B-cell lymphoma (DLBCL) in the rituximab era has not been well defined. We sought to evaluate the use of imaging (computed tomography [CT] and positron emission tomography [PET]-CT) scans and lactate dehydrogenase (LDH) in surveillance of patients with stage I to II DLBCL. Methods: A retrospective analysis was performed of patients who received definitive treatment between 2000 and 2013. Results: One hundred sixty-two consecutive patients with stage I to II DLBCL were treated with chemotherapy +/− rituximab, radiation, or combined modality therapy. The 5-year rates of overall survival (OS) and freedommore » from progression (FFP) were 81.2% and 80.8%, respectively. Of the 162 patients, 124 (77%) were followed up with at least 1 surveillance PET scan beyond end-of-treatment scans; of those, 94 of 124 (76%) achieved a complete metabolic response on PET scan after completion of chemotherapy, and this was associated with superior FFP (P=.01, HR=0.3) and OS (P=.01, HR 0.3). Eighteen patients experienced relapse after initial response to therapy. Nine relapses were initially suspected by surveillance imaging studies (8 PET, 1 CT), and 9 were suspected clinically (5 by patient-reported symptoms and 4 by symptoms and physical examination). No relapses were detected by surveillance LDH. The median duration from initiation of treatment to relapse was 14.3 months among patients with relapses suspected by imaging, and 59.8 months among patients with relapses suspected clinically (P=.077). There was no significant difference in OS from date of first therapy or OS after relapse between patients whose relapse was suspected by imaging versus clinically. Thirteen of 18 patients underwent successful salvage therapy after relapse. Conclusions: A complete response on PET scan immediately after initial chemotherapy is associated with superior FFP and OS in stage I to II DLBCL. The use of PET scans as posttreatment surveillance is not associated with a survival advantage. LDH is not a sensitive marker for relapse. Our results argue for limiting the use of posttreatment surveillance in patients with limited-stage DLBCL.« less

Ulcerative colitis (UC) is a chronic relapsing inflammatory bowel disease. Psychological factors such as depression and stress are under debate to contribute to the risk of relapse. The impact of mucosal healing to reduce the risk of relapse had not been studied prospectively. The aim of this study was to identify whether depression and stress increase and mucosal healing reduces the risk of clinical relapse in patients with UC in clinical remission. Patients in clinical remission were followed prospectively for 1 year, or less if they relapsed. Endoscopy and histology score and long-term perceived stress (Perceived Stress Questionnaire) were measured at baseline. Mucosal healing was defined by a Mayo Endoscopy score of 0-1. Depression (Hospital Anxiety and Depression Scale) and acute perceived stress (Cohen Perceived Stress Scale) were measured at baseline and after 1, 3, 6, 9, and 12 months. A time-dependent multivariate Cox regression model determined the predictors of time to relapse. Seventy-five patients were included into final analysis, of which 28 (37.3%) relapsed. Short-term stress at the last visit before relapse (hazard ratio [HR] = 1.05, 95% confidence interval [CI] = 1.01-1.10) and male gender (HR = 2.38, 95% CI = 1.01-5.61), but not baseline mucosal healing (HR = 0.86, 95% CI = 0.35-2.11), baseline long-term stress (HR = 0.20, 95% CI = 0.01-3.31), and depression at the last visit before relapse (HR = 1.08, 95% CI = 0.95-1.22) were predictive for a relapse. Short-term stress but not depression nor mucosal healing was predictive for the risk of relapse in patients with UC in clinical remission. Larger multicentre studies are necessary to confirm our findings.

In the CORAL study, 255 chemosensitive relapses with diffuse large B-cell lymphoma (DLBCL) were consolidated with autologous stem cell transplantation (ASCT), and 75 of them relapsed thereafter. The median time between ASCT and progression was 7.1 months. The median age was 56.1 years; tertiary International Prognosis Index (tIPI) observed at relapse was 0-2 in 71.6% of the patients and >2 in 28.4%. The overall response rate to third-line chemotherapy was 44%. The median overall survival (OS) was 10.0 months (median follow-up: 32.8 months). Thirteen patients received an allogeneic SCT, and three a second ASCT. The median OS was shorter among patients who relapsed <6 months (5.7 months) compared with those relapsing ⩾12 months after ASCT (12.6 months, P=0.0221). The median OS in patients achieving CR, PR or no response after the third-line regimen was 37.7 (P<0.0001), 10.0 (P=0.03) and 6.3 months, respectively. The median OS varied according to tIPI: 0-2: 12.6 months and >2: 5.3 months (P=0.0007). In multivariate analysis, tIPI >2, achievement of response and remission lasting <6 months predicted the OS. This report identifies the prognostic factors for DLBCL relapsing after ASCT and thus helps to select patients for experimental therapy.

[Central nervous system relapse in diffuse large B cell lymphoma: Risk factors].

PubMed

Sancho, Juan-Manuel; Ribera, Josep-Maria

2016-01-15

Central nervous system (CNS) involvement by lymphoma is a complication associated, almost invariably, with a poor prognosis. The knowledge of the risk factors for CNS relapse is important to determine which patients could benefit from prophylaxis. Thus, patients with very aggressive lymphomas (such as lymphoblastic lymphoma or Burkitt's lymphoma) must systematically receive CNS prophylaxis due to a high CNS relapse rate (25-30%), while in patients with indolent lymphoma (such as follicular lymphoma or marginal lymphoma) prophylaxis is unnecessary. However, the question about CNS prophylaxis in patients with diffuse large B-cell lymphoma (DLBCL), the most common type of lymphoma, remains controversial. The information available is extensive, mainly based on retrospective and heterogeneous studies. There seems that immunochemotherapy based on rituximab reduces the CNS relapse rate. On the other hand, patients with increased serum lactate dehydrogenase plus more than one extranodal involvement seem to have a higher risk of CNS relapse, but a prophylaxis strategy based only on the presence of these 2 factors does not prevent all CNS relapses. Patients with involvement of testes or breast have high risk of CNS relapse and prophylaxis is mandatory. Finally, CNS prophylaxis could be considered in patients with DLBCL and renal or epidural space involvement, as well as in those cases with MYC rearrangements, although additional studies are necessary.

Central nervous system (CNS) relapse in non-Hodgkin lymphoma (NHL) is a rare but serious complication that carries a poor prognosis. The use of infusional etoposide, prednisone, vincristine, cyclophosphamide, doxorubicin, and rituximab (EPOCH-R) for frontline treatment of diffuse large B cell lymphoma (DLBCL) is increasing, though little is known about incidence of and risk factors for CNS relapse with this regimen PATIENTS AND METHODS: We completed a chart review of patients with NHL who received EPOCH-R as front line therapy. Data obtained included baseline and treatment characteristics including if patients received CNS directed therapy. We measured overall survival (OS), progression free survival (PFS), and progression to CNS involvement. We identified 223 patients who met the inclusion criteria, 72% had DLBCL. Of all the patients, 5.8% experienced CNS relapse, and 38.6% were treated with CNS prophylaxis. There was no difference in rate of CNS relapse, OS, or PFS between patients who had and had not received CNS prophylaxis. Patients whose serum lactate dehydrogenase was greater than twice the upper limit of normal at diagnosis and those with extranodal disease were significantly more likely to have CNS relapse (P = .0247 and 0.022, respectively) than their counterparts. The rate of CNS relapse in this patient population approaches 6%, not significantly different from reports on those receiving R-CHOP. The results of this study suggest that CNS prophylaxis might be more selectively used among patients treated with EPOCH-R with certain high-risk features. © 2017 Wiley Periodicals, Inc.

An observational study has suggested that relapsing-remitting multiple sclerosis patients with helminth infections have lower disease activity and progression than uninfected multiple sclerosis patients. To evaluate the safety and efficacy on MRI activity of treatment with TSO in relapsing MS. The study was an open-label, magnetic resonance imaging assessor-blinded, baseline-to-treatment study including ten patients with relapsing forms of multiple sclerosis. Median (range) age was 41 (24-55) years, disease duration 9 (4-34) years, Expanded Disability Status Scale score 2.5 (1-5.0), and number of relapses within the last two years 3 (2-5). Four patients received no disease modifying therapy, while six patients received IFN-β. After an observational period of 8 weeks, patients received 2500 ova from the helminth Trichuris suis orally every second week for 12 weeks. Patients were followed with serial magnetic resonance imaging, neurological examinations, laboratory safety tests and expression of immunological biomarker genes. Treatment with Trichuris suis orally was well-tolerated apart from some gastrointestinal symptoms. Magnetic resonance imaging revealed 6 new or enlarged T2 lesions in the run-in period, 7 lesions in the early period and 21 lesions in the late treatment period. Two patients suffered a relapse before treatment and two during treatment. Eight patients developed eosinophilia. The expression of cytokines and transcription factors did not change. In a small group of relapsing multiple sclerosis patients, Trichuris suis oral therapy was well tolerated but without beneficial effect. © The Author(s), 2015.

Pyrexia-associated Relapse in Chronic Inflammatory Demyelinating Polyradiculoneuropathy: A Case Report.

Ueda, Jun; Yoshimura, Hajime; Kohara, Nobuo

2018-04-27

Chronic inflammatory demyelinating polyradiculoneuropathy is a relapsing-remitting or chronic progressive demyelinating polyradiculoneuropathy. We report the case of a patient with chronic inflammatory demyelinating polyradiculoneuropathy who experienced relapses on four occasions after experiencing pyrexia and flu-like symptoms. Our patient showed characteristic features, such as relapse after pyrexia and flu-like symptoms, remission after pyretolysis without treatment, and the absence of remarkable improvement in a nerve conduction study in the remission phase. The serum level of tumor necrosis factor-α was elevated in the relapse phase and reduced in the remission phase; thus, the induction of cytokine release by viral infection might have caused the relapses.

Purpose Lenalidomide and bortezomib are active in relapsed and relapsed/refractory multiple myeloma (MM). In preclinical studies, lenalidomide sensitized MM cells to bortezomib and dexamethasone. This phase I, dose-escalation study (ie, NCT00153933) evaluated safety and determined the maximum-tolerated dose (MTD) of lenalidomide plus bortezomib in patients with relapsed or with relapsed and refractory MM. Patients and Methods Patients received lenalidomide 5, 10, or 15 mg/d on days 1 through 14 and received bortezomib 1.0 or 1.3 mg/m2 on days 1, 4, 8, and 11 of 21-day cycles. Dexamethasone (20mg or 40 mg on days 1, 2, 4, 5, 8, 9, 11, and 12) was added for progressive disease after two cycles. Primary end points were safety and MTD determination. Results Thirty-eight patients were enrolled across six dose cohorts. The MTD was lenalidomide 15 mg/d plus bortezomib 1.0 mg/m2. Dose-limiting toxicities (n = 1 for each) were grade 3 hyponatremia and herpes zoster reactivation and grade 4 neutropenia. The most common treatment-related, grades 3 to 4 toxicities included reversible neutropenia, thrombocytopenia, anemia, and leukopenia. Among 36 response-evaluable patients, 61% (90% CI, 46% to 75%) achieved minimal response or better. Among 18 patients who had dexamethasone added, 83% (90% CI, 62% to 95%) achieved stable disease or better. Median overall survival was 37 months. Conclusion Lenalidomide plus bortezomib was well tolerated and showed promising activity with durable responses in patients with relapsed and relapsed/refractory MM, including patients previously treated with lenalidomide, bortezomib, and/or thalidomide. The combination of lenalidomide, bortezomib, and dexamethasone is being investigated in a phase II study in this setting and in newly diagnosed MM. PMID:19786667

This study analyzed clinical long-term outcomes after endoscopic therapy, including the incidence and treatment of relapse. This study included 19 consecutive patients (12 male, 7 female, median age 54 years) with obstructive chronic pancreatitis who were admitted to the 2(nd) Medical Department of the Technical University of Munich. All patients presented severe chronic pancreatitis (stage III°) according to the Cambridge classification. The majority of the patients suffered intermittent pain attacks. 6 of 19 patients had strictures of the pancreatic duct; 13 of 19 patients had strictures and stones. The first endoscopic retrograde pancreatography (ERP) included an endoscopic sphincterotomy, dilatation of the pancreatic duct, and stent placement. The first control ERP was performed 4 wk after the initial intervention, and the subsequent control ERP was performed after 3 mo to re-evaluate the clinical and morphological conditions. Clinical follow-up was performed annually to document the course of pain and the management of relapse. The course of pain was assessed by a pain scale from 0 to 10. The date and choice of the therapeutic procedure were documented in case of relapse. Initial endoscopic intervention was successfully completed in 17 of 19 patients. All 17 patients reported partial or complete pain relief after endoscopic intervention. Endoscopic therapy failed in 2 patients. Both patients were excluded from further analysis. One failed patient underwent surgery, and the other patient was treated conservatively with pain medication. Seventeen of 19 patients were followed after the successful completion of endoscopic stent therapy. Three of 17 patients were lost to follow-up. One patient was not available for interviews after the 1(st) year of follow-up. Two patients died during the 3(rd) year of follow-up. In both patients chronic pancreatitis was excluded as the cause of death. One patient died of myocardial infarction, and one patient succumbed to pneumonia. All three patients were excluded from follow-up analysis. Follow-up was successfully completed in 14 of 17 patients. 4 patients at time point 3, 2 patients at time point 4, 3 patients at time point 5 and 2 patients at time point 6 and time point 7 used continuous pain medication after endoscopic therapy. No relapse occurred in 57% (8/14) of patients. All 8 patients exhibited significantly reduced or no pain complaints during the 5-year follow-up. Seven of 8 patients were completely pain free 5 years after endoscopic therapy. Only 1 patient reported continuous moderate pain. In contrast, 7 relapses occurred in 6 of the 14 patients. Two relapses were observed during the 1(st) year, 2 relapses occurred during the 2(nd) year, one relapse was observed during the 3(rd) year, one relapse occurred during the 4(th) year, and one relapse occurred during the 5(th) follow-up year. Four of these six patients received conservative treatment with endoscopic therapy or analgesics. Relapse was conservatively treated using repeated stent therapy in 2 patients. Analgesic treatment was successful in the other 2 patients. 57% of patients exhibited long-term benefits after endoscopic therapy. Therefore, endoscopic therapy should be the treatment of choice in patients being inoperable or refusing surgical treatment.

Objective To determine whether starting antidepressant medication at the start of ECT reduces postECT relapse and to determine whether continuation pharmacotherapy with nortriptyline and lithium (NT-Li) differs in efficacy or side effects from continuation pharmacotherapy with venlafaxine and lithium (VEN-Li). Method During an acute ECT phase, 319 patients were randomized to treatment with moderate dosage bilateral ECT or high dosage right unilateral ECT. They were also randomized to concurrent treatment with placebo, NT, or VEN. Of 181 patients to meet postECT remission criteria, 122 (67.4%) participated in a second continuation pharmacotherapy phase. Patients earlier randomized to NT or VEN continued on the antidepressant, while patients earlier randomized to placebo were now randomized to NT or VEN. Li was added for all patients who were followed until relapse or 6 months. Results Starting an antidepressant medication at the beginning of the ECT course did not impact on the rate or timing of relapse relative to starting pharmacotherapy after ECT completion. The combination of NT-Li did not differ from VEN-Li in any relapse or side effect measure. Older age was strongly associated with lower relapse risk, whereas the type of ECT administered in the acute phase and medication resistance were not predictive. Across sites, 50% of patients relapsed, 33.6% continued in remission 6 months postECT, and 16.4% dropped out. Conclusions Starting an antidepressant medication during ECT does not impact relapse and there are concerns about administering Li during an acute ECT course. Nortriptyline and venlafaxine were equally effective in prolonging remission, although relapse rates following ECT are substantial despite intensive pharmacology. As opposed to the usual abrupt cessation of ECT, the impact of an ECT taper should be evaluated. PMID:23303417

Plasma exchange (PE) is well established for conditions such as rapid progressive vasculitis associated with autoantibodies against neutrophil cytoplasmic antigens (ANCA), anti-glomerular basement membrane (GBM) antibody disease, or thrombotic thrombocytopenic purpura (TTP). Also, several neurological disorders, such as acute worsening in myasthenia gravis, Guillan-Barré syndrome (GBS) and chronic inflammatory demyelinating polyneuropathy (CIDP), can successfully be treated with PE. Only small case series have previously shown that PE is also effective in relapses in patients with multiple sclerosis (MS). We report our experiences of PE therapy in a series of 20 patients with 21 steroid unresponsive MS relapses. A marked-to-moderate clinical response with clear gain of function in 76% of patients with uni- or bilateral optic neuritis and in 87.5% of patients with relapses other than optic neuritis was observed. PE is an effective and well tolerated therapeutic option for steroid-unresponsive MS relapses.

Thirty male alcohol dependent inpatients without concurrent depressive disorder, 13 of them with a positive family history of alcohol dependence in a first degree relative (PFH), were questioned about their desire and consumption habits with respect to cigarettes, coffee, and sweets while on a three-week inpatient treatment after detoxification from alcohol. Six weeks after discharge from hospital, the patients were reassessed for relapse. Eleven patients (36.6%) had relapsed at follow-up. Relapsers were younger than abstainers. The days until relapse correlated negatively with intensity of desire to drink alcohol, desire to smoke cigarettes, and with a higher consumption of cigarettes. PFH patients did not relapse earlier but they had a stronger desire to drink coffee and eat sweets and had a higher coffee consumption.

Several randomised trials have confirmed the benefit of adjuvant trastuzumab for patients with HER2-positive early breast cancer. However, concern has been expressed that adjuvant trastuzumab might be associated with an increased frequency of CNS relapses. We assessed the frequency and course of CNS relapses, either as first event or at any time, using data from the HERA trial. We estimated the cumulative incidence of first disease-free survival (DFS) events in the CNS versus other sites by competing risks analysis in patients with HER2-positive early breast cancer who had been randomly assigned to receive 1 year of trastuzumab or to observation in the HERA trial after a median follow-up of 4 years (IQR 3·5-4·8). To obtain further information about CNS relapse at any time before death, we circulated a data collection form to investigators to obtain standardised information about CNS events that occurred in all patients who had died before July, 2009. We estimated the cumulative incidence of CNS relapse at any time with a competing risks analysis. Of 3401 patients who had been assigned to receive 1 year of trastuzumab or to observation, 69 (2%) had a CNS relapse as first DFS event and 747 (22%) had a first DFS event not in the CNS. The frequency of CNS relapses as first DFS event did not differ between the group given 1 year of trastuzumab (37 [2%] of 1703 patients) and the observation group (32 [2%] of 1698; p=0·55 [Gray's test]). 481 data collection forms were distributed, of which 413 (86%) were returned. The proportion of patients who had died and experienced a CNS relapse was numerically higher in the observation group (129 [57%] of 227) than in the group given trastuzumab for 1 year (88 [47%] of 186; p=0·06 [Gray's test]). Most CNS relapses were symptomatic (189 [87%] of 217). Adjuvant trastuzumab does not increase the risk of CNS relapse in patients with HER2-positive early breast cancer. None.

The aim of this study was to evaluate the addition of cyclophosphamide in relapsed-refractory multiple myeloma patients (RRMM) who experienced biochemical relapse or progression without CRAB, during treatment with lenalidomide and dexamethasone (Rd), to slow down the progression in active relapse. This analysis included 31 patients with RRMM treated with Rd who received cyclophosphamide (CRd) at biochemical relapse. The CRd regimen was continued until disease progression. The median number of CRd cycles administered was 8 (range: 1-35). A response was observed in 9 (29%) patients. After a median observation time of 11 months, the median overall survival (OS) from the beginning of CRd was 17.7 months. The median progression-free survival (PFS) from the beginning of CRd was 13.1 months. The addition of cyclophosphamide delays the progression in patients who present a biochemical relapse during Rd treatment. The response rate and the duration of PFS obtained with minimal toxicities and low costs induced us to setting up a randomized clinical trial. © 2018 John Wiley & Sons A/S.

Forty-seven percent of adults with acute myeloid leukemia (AML) who entered the ALFA-9802 trial and achieved a first complete remission (CR) experienced a first relapse. We examined the outcome of these 190 adult patients. Eighty-four patients (44%) achieved a second CR. The median overall survival (OS) after relapse was 8.9 months with a 2-year OS at 25%. Factors predicting a better outcome after relapse were stem cell transplant (SCT) performed in second CR and a first CR duration >1 year. Risk groups defined at the time of diagnosis and treatment received in first CR also influenced the outcome after relapse. The best results were obtained in patients with core binding factor (CBF)-AML, while patients initially defined as favorable intermediate risk showed a similar outcome after relapse than those initially entering the poor risk group. We conclude that most adult patients with recurring AML could not be rescued using current available therapies, although allogeneic SCT remains the best therapeutic option at this stage of the disease.

The prognosis of patients with acute lymphoblastic leukemia (ALL) and central nervous system (CNS) relapse has historically been very poor. Although chemo-radiotherapy has improved outcomes, some patients still have a poor prognosis after CNS relapse. Therefore, allogeneic hematopoietic stem cell transplantation (allo-SCT) has recently become an option for treatment of CNS leukemia; however, information, particularly on the long-term outcome of transplant recipients, is limited. We performed allo-SCT in eight pediatric patients with ALL (n=7) or T-cell type non-Hodgkin's lymphoma (n=1), who had isolated CNS relapse. All patients survived for a median of 70.5 (range, 13-153) months after SCT. Sequelae developed late in some patients: mental retardation (IQ=47) in one patient, severe alopecia in two patients, limited chronic graft-versus-host-disease in three patients, and amenorrhea and/or hypothyroidism in three patients. Except for a pre-school child with post transplant CNS relapse, six out of seven patients show normal school/social performance. Our results clearly indicate a high cure rate of isolated CNS relapse by allo-SCT in pediatric lymphoid malignancies; however, there needs to be further studies to determine which are the appropriate candidates for transplantation and what is the best transplant regimen to achieve high cure rate and maintain good quality of life.

Since the outcome of relapsed/refractory aggressive non-Hodgkin's lymphoma (NHL) is highly variable, a risk-adapted treatment approach was evaluated. After two cycles of DHAP, patients received high-dose treosulfan/etoposide/carboplatinum (TEC) and autologous stem cell rescue. After TEC, low-risk patients with late relapse (>1 year after first CR who achieved CR after DHAP received no further treatment. Patients with late relapse who achieved CR or PR only after TEC underwent a second cycle of TEC. High-risk patients with early relapse/refractory disease received treosulfan/fludarabine followed by allogeneic transplantation. Rituximab was added in patients with B-cell lymphoma (86%). At entry, 36% of all 57 patients had refractory disease, 32% early and 32% late relapse. During DHAP treatment, progression occurred in 32% of patients. Of 33 patients who received TEC, 5 received second TEC and 15 allogeneic transplantation. Main toxicity after TEC was oral mucositis (CTC grades 3 and 4 in 50% and 13%, respectively). In total, 42% patients achieved CR. Median OS was 21.4 months for all patients and 32.6 for those who underwent allogeneic transplantation. International prognostic index (IPI) at study entry was highly discriminative at predicting OS (P<0.0001). Risk-adapted, treosulfan-based therapy with auto- and allo-SCT is feasible. Long-term survival is possible with allogeneic transplantation.

Cytomegalovirus (CMV) DNA load was analyzed as a marker for relapse of CMV infection in 24 solid organ transplant patients with CMV infection or disease who received a fixed 14-day course of intravenous ganciclovir. Viral load was measured in blood samples obtained before and at the completion of treatment. Eight (33%) of 24 patients developed relapsing CMV infection. Median pretreatment viral loads were higher in the relapsing group (80,150 copies/106 leukocytes) than in the nonrelapsing group (5500 copies/106 leukocytes; P=.007). The relapsing group also had persistent detectable viral DNA (median, 5810 copies/106 leukocytes) after treatment, whereas it was undetectable in the nonrelapsing group (P<. 0001). Primary CMV infection (seronegative recipients of seropositive organs, D+R-) was an independent marker for CMV relapse (P=.03), and these patients had higher pre- and posttreatment viral loads than did non-D+/R- patients (P<.0001 and P=.0014, respectively). CMV DNA load is a useful marker for individualizing antiviral treatment of CMV infection in solid organ transplant recipients.

Swallowing mechanism and neurogenic dysphagia in MS have been rarely studied by electromyographical (EMG) methods. This study aims to evaluate the presence of subclinical dysphagia in patients with mild multiple sclerosis (MS) using electrophysiological methods. A prospective study of 51 patients with relapsing remitting multiple sclerosis and 18 age-matched healthy adults was investigated. We used electromyography to measure the activity of the submental muscles during swallowing. Electrophysiological recordings of patients were obtained during relapse, after relapse, and at any time in remission period. Clinical dysphagia was found in 12% of MS patients, while electrophysiological swallowing abnormalities were encountered in 33% of patients. Subclinical dysphagia was determined in 35% of patients during an MS relapse, in 20% of patients after a relapse, and in 25% of all 51 patients in the remission period based on EMG findings. Duration of swallowing signal of submental muscles in all MS patients was found to be longer than in normal subjects (p = 0.001). During swallowing of 50 ml of sequential water, the compensatory respiratory cycles occurred more often in MS patients than normal subjects, especially during a relapse (p = 0.005). This is the first study investigating swallowing abnormalities and subclinical dysphagia from the electrophysiological aspect in MS patients with mild disability. The electrophysiological tests described in this study are useful to uncover subclinical dysphagia since they have the advantage of being rapid, easy to apply, non-invasive, and without risk for the patients.

We investigated the impact of donor type on post-relapse survival (PRS) in 85 patients with hematological relapse after their first allogeneic hematological stem cell transplantation (allo-HSCT) for hematological malignancy. The median follow-up was 64 months among survivors. Both 3-year overall survival and 3-year PRS were similar in haploidentical donor (HID) and matched sibling donor (MRD) transplantation (13.0%±4.7% vs 19.4%±7.1%, P=0.913 and 7.7±3.9% vs 9.7±5.3%, P= 0.667). Higher rates of post-relapse grade II-IV and III-IV acute GvHD (aGvHD) were observed in HID transplantation patients. A higher cumulative incidence of post-relapse extensive chronic GvHD was also observed for HID transplantation patients. Multivariate analyses confirmed that treatment including donor lymphocyte infusion (DLI), late relapse >1 year, and in first CR at transplantation were associated with superior PRS (P=0.012, hazard ratio (HR)=0.527 (0.320-0.866)); P=0.033, HR=0.534 (0.300-0.952) and P=0.046, HR=0.630 (0.400-0.992). The data suggest that post-relapse outcomes are comparable in HID and MRD transplantation, and that DLI is safe for relapsed patients after haploidentical transplantation.

The BET bromodomain inhibitor CPI203 improves lenalidomide and dexamethasone activity in in vitro and in vivo models of multiple myeloma by blockade of Ikaros and MYC signaling

Most patients with multiple myeloma treated with current therapies, including immunomodulatory drugs, eventually develop relapsed/refractory disease. Clinical activity of lenalidomide relies on degradation of Ikaros and the consequent reduction in IRF4 expression, both required for myeloma cell survival and involved in the regulation of MYC transcription. Thus, we sought to determine the combinational effect of an MYC-interfering therapy with lenalidomide/dexamethasone. We analyzed the potential therapeutic effect of the combination of the BET bromodomain inhibitor CPI203 with the lenalidomide/dexamethasone regimen in myeloma cell lines. CPI203 exerted a dose-dependent cell growth inhibition in cell lines, indeed in lenalidomide/dexamethasone-resistant cells (median response at 0.5 μM: 65.4%), characterized by G1 cell cycle blockade and a concomitant inhibition of MYC and Ikaros signaling. These effects were potentiated by the addition of lenalidomide/dexamethasone. Results were validated in primary plasma cells from patients with multiple myeloma co-cultured with the mesenchymal stromal cell line stromaNKtert. Consistently, the drug combination evoked a 50% reduction in cell proliferation and correlated with basal Ikaros mRNA expression levels (P=0.04). Finally, in a SCID mouse xenotransplant model of myeloma, addition of CPI203 to lenalidomide/dexamethasone decreased tumor burden, evidenced by a lower glucose uptake and increase in the growth arrest marker GADD45B, with simultaneous downregulation of key transcription factors such as MYC, Ikaros and IRF4. Taken together, our data show that the combination of a BET bromodomain inhibitor with a lenalidomide-based regimen may represent a therapeutic approach to improve the response in relapsed/refractory patients with multiple myeloma, even in cases with suboptimal prior response to immunomodulatory drugs.

We evaluated progression-free survival (PFS) rate of patients treated with lenalidomide/dexamethasone (Len/Dex), the efficacy of the combination, and the prognostic significance of treatment at biochemical vs. clinical relapse on PFS in 207 consecutive myeloma patients treated with Len/Dex in second line, according to routine clinical practice in Greece. First-line treatment included bortezomib-based (63.3%) or immunomodulatory drug-based (34.8%) therapies; 25% of patients underwent autologous stem cell transplantation. Overall response rate was 73.4% (17.8% complete response and 23.7% very good partial response); median time to best response was 6.7 months. Overall, median PFS and 12-month PFS rate was 19.2 months and 67.6%, respectively. 67.5% of patients had biochemical relapse and 32.5% had clinical relapse prior to initiation of Len/Dex. Median PFS was 24 months for patients treated at biochemical relapse vs. 13.2 months for those treated at clinical relapse (HR:0.63, p = 0.006) and the difference remained significant after adjustment for other prognostic factors. Type of relapse was the strongest prognostic factor for PFS in multivariate analysis. These real-world data confirm the efficacy of Len/Dex combination at first relapse; more importantly, it is demonstrated for the first time outside a clinical trial setting that starting therapy with Len/Dex at biochemical, rather than at clinical relapse, is a significant prognostic factor for PFS, inducing a 37% reduction of the probability of disease progression or death.

To evaluate the efficacy of methotrexate (MTX) and the effect of its withdrawal on relapse rate of uveitis associated with juvenile idiopathic arthritis (JIA). Retrospective case series. Data of 22 pediatric JIA patients who were being treated with MTX for active uveitis were studied retrospectively. Relapse rate after the withdrawal of MTX was established. Anterior chamber (AC) inflammation, topical steroid use during the first year of MTX treatment, and associations of relapses after the withdrawal were evaluated statistically. Duration of MTX treatment and its withdrawal was determined individually in collaboration with a rheumatologist with an intention to continue the treatment for at least 1 year and to withdraw in case of inactivity of uveitis and arthritis. Inactivity of uveitis was defined as the presence of ≤0.5+ cells in the AC. Eighteen patients (18/22; 82%) showed improvement of their uveitis with a significant decrease in activity of AC inflammation after a minimal period of 3 months of MTX treatment. A topical steroid-sparing effect was observed when MTX was administered for a period of 3 to 9 months. MTX was discontinued because of inactive uveitis in 13 patients. In 9 patients (8/13; 69%) a relapse of uveitis was observed after a mean time of 7.5 months (± SD 7.3). Six patients (6/13; 46%) had a relapse within the first year after the withdrawal. Relapse-free survival after withdrawal of MTX was significantly longer in patients who had been treated with MTX for more than 3 years (P = .009), children who were older than 8 years at the moment of withdrawal (P = .003), and patients who had an inactivity of uveitis of longer than 2 years before withdrawal of MTX (P = .033). Longer inactivity under MTX therapy was independently protective for relapses after the withdrawal (hazard ratio = 0.07; 95% confidence interval 0.01-0.86; P = .038), which means that 1-year increase of duration of inactive uveitis before the withdrawal of MTX results in a decrease of hazard for new relapse of 93%. A high number of patients with inactive uveitis relapse quickly after the withdrawal of MTX. Our results suggest that a longer period of inactivity prior to withdrawal and a longer treatment period with MTX reduce the chance of relapse after withdrawal. Copyright © 2011 Elsevier Inc.

Serial assays of qualitative (multiplex and nested) and quantitative PCR were carried out for detecting and estimating the level of BCR-ABL transcripts in 39 CML patients following bone marrow transplantation. Seven of these patients, who received donor lymphocyte infusions (DLIs) following to relapse, were also monitored. Quantitative estimates of BCR-ABL transcripts were obtained by co-amplification with a competitor sequence. Estimates of ABL transcripts were used, an internal control and the ratio BCR-ABL/ABL was thus estimated for evaluating the kinetics of residual clones. Twenty four patients were followed shortly after BMT; two of these patients were in cytogenetic relapse coexisting with very high BCR-ABL levels while other 22 were in clinical, haematologic and cytogenetic remission 2-42 months after BMT. In this latter group, seven patients showed a favourable clinical-haematological progression in association with molecular remission while in 14 patients quantitative PCR assays indicated molecular relapse that was not associated with an early cytogenetic-haematologic relapse. BCR-ABL/ABL levels could not be correlated with presence of GVHD in 24 patients after BMT. In all seven patients treated with DLI, high levels of transcripts were detected at least 4 months before the appearance of clinical haematological relapse. Following DLI, five of these patients showed decreasing transcript levels from 2 to 5 logs between 4 and 12 months. In eight other patients studied long after BMT, five showed molecular relapse up to 117 months post-BMT and only one showed cytogenetic relapse. Our findings indicated that quantitative estimates of BCR-ABL transcripts were valuable for monitoring minimal residual disease in each patient.

The study was designed to determine whether response-based therapy improves outcomes in intermediate-risk Hodgkin lymphoma. We examined patterns of first relapse in the study. From September 2002 to July 2010, 1712 patients <22 years old with stage I-IIA with bulk, I-IIAE, I-IIB, and IIIA-IVA with or without doxorubicin, bleomycin, vincristine, etoposide, prednisone, and cyclophosphamide were enrolled. Patients were categorized as rapid (RER) or slow early responders (SER) after 2 cycles of doxorubicin, bleomycin, vincristine, etoposide, prednisone, and cyclophosphamide (ABVE-PC). The SER patients were randomized to 2 additional ABVE-PC cycles or augmented chemotherapy with 21 Gy involved field radiation therapy (IFRT). RER patients were stipulated to undergo 2 additional ABVE-PC cycles and were then randomized to 21 Gy IFRT or no further treatment if complete response (CR) was achieved. RER without CR patients were non-randomly assigned to 21 Gy IFRT. Relapses were characterized without respect to site (initial, new, or both; and initial bulk or initial nonbulk), and involved field radiation therapy field (in-field, out-of-field, or both). Patients were grouped by treatment assignment (SER; RER/no CR; RER/CR/IFRT; and RER/CR/no IFRT). Summary statistics were reported. At 4-year median follow-up, 244 patients had experienced relapse, 198 of whom were fully evaluable for review. Those who progressed during treatment (n=30) or lacked relapse imaging (n=16) were excluded. The median time to relapse was 12.8 months. Of the 198 evaluable patients, 30% were RER/no CR, 26% were SER, 26% were RER/CR/no IFRT, 16% were RER/CR/IFRT, and 2% remained uncategorized. The 74% and 75% relapses involved initially bulky and nonbulky sites, respectively. First relapses rarely occurred at exclusively new or out-of-field sites. By contrast, relapses usually occurred at nodal sites of initial bulky and nonbulky disease. Although response-based therapy has helped define treatment for selected RER patients, it has not improved outcome for SER patients or facilitated refinement of IFRT volumes or doses.

Limited data are available to help identify patients with schizophrenia who are most likely to benefit from long-acting injectable antipsychotics. To investigate the efficacy of long-acting injectable antipsychotic paliperidone palmitate one-month formulation for preventing relapses, factors influencing time to first relapse, and the effect of different antipsychotic adherence levels on time to first relapse in Chinese patients with schizophrenia. This was a post-hoc analysis from an open-label, single-arm study of stable patients (Positive and Negative Syndrome Scale total score <70; n=367) receiving paliperidone palmitate one-month formulation at the end of an acute 13-week treatment phase, who entered a naturalistic one-year follow-up period, either continuing with flexibly dosed paliperidone palmitate one-month formulation (75-150 mg eq.) or switching to another antipsychotic(s). There were 362/367 patients (age=31.4±10.75 years) included in the analysis of time to first relapse (primary outcome) and 327/362 patients (39/327, poor antipsychotic adherence (<80%)) willing to receive antipsychotics were included in the exposure/adherence analysis. Overall, 84.6% (95% confidence interval=79.2-88.7) patients remained relapse-free. Poor adherence during follow-up (hazard ratio=2.97, 95% confidence interval=1.48-5.98, p=0.002) and frequent hospitalizations in the previous year (hazard ratio=1.29, 95% confidence interval=1.02-1.62, p=0.03) were associated with a significant risk of shorter time to first relapse in the univariate analysis. In patients with poor adherence, 'no use' (hazard ratio=13.13, 95% confidence interval=1.33-129.96, p=0.03) and 'interrupted use' (hazard ratio=11.04, 95% confidence interval=1.03-118.60, p=0.047) of paliperidone palmitate one-month formulation (vs continued use) showed a significantly higher risk of relapse; this was not observed in patients with good (≥80%) antipsychotic adherence. No new safety concerns were identified. Continued use of paliperidone palmitate one-month formulation/long-acting injectable antipsychotic was effective in preventing schizophrenia relapses, especially in patients with suboptimal antipsychotic adherence.

Hormonal therapy with androgen suppression is a common treatment for advanced prostate tumors. The emergence of androgen-independent cells, however, leads to a tumor relapse under a condition of long-term androgen deprivation. Clinical trials suggest that intermittent androgen suppression (IAS) with alternating on- and off-treatment periods can delay the relapse when compared with continuous androgen suppression (CAS). In this paper, we propose a mathematical model for prostate tumor growth under IAS therapy. The model elucidates initial hormone sensitivity, an eventual relapse of a tumor under CAS therapy, and a delay of a relapse under IAS therapy, which are due to the coexistence of androgen-dependent cells, androgen-independent cells resulting from reversible changes by adaptation, and androgen-independent cells resulting from irreversible changes by genetic mutations. The model is formulated as a free boundary problem of partial differential equations that describe the evolution of populations of the abovementioned three types of cells during on-treatment periods and off-treatment periods. Moreover, the model can be transformed into a piecewise linear ordinary differential equation model by introducing three new volume variables, and the study of the resulting model may help to devise optimal IAS schedules.

Early indicators of relapses vs pseudorelapses in neuromyelitis optica spectrum disorder

PubMed Central

Kessler, Remi A.; Mealy, Maureen A.

2016-01-01

Objective: The purpose of this study was to review cases of neuromyelitis optica spectrum disorder (NMOSD) relapses and pseudorelapses to identify early features that differentiate between them at onset of symptoms. Methods: This was a retrospective analysis of 74 hospitalizations of patients with NMOSD who were admitted to the Johns Hopkins Hospital for workup and treatment of a presumed relapse. Standard workup included MRI and blood and urine testing for metabolic and infectious etiologies. The gold standard for a relapse was defined as new or worsening symptoms and a change in neurologic examination correlating with a new or enhancing MRI lesion. A pseudorelapse was a clinical exacerbation with similar symptoms and signs but the MRI was negative, and workup identified an alternative cause for the symptoms that, when treated, resulted in the improvement of neurologic symptoms. Factors considered to be early predictors of relapses vs pseudorelapses were analyzed using the Fisher test. Results: Among 74 NMOSD hospitalizations for presumed relapse, 57 were confirmed relapses while 17 had a negative MRI and an identifiable cause of pseudorelapse. The most common causes of pseudorelapse were infection, pain, and dysautonomia. The only early predictor that reliably differentiated relapse from pseudorelapse among this NMOSD patient population was vision loss (p = 0.039). Race, sex, presentations of weakness, numbness, and bowel/bladder dysfunction, white blood cell count, and urinary tract infection were not different among patients with relapses vs pseudorelapses. Conclusions: Vision loss in NMOSD is strongly suggestive of a true relapse vs a pseudorelapse. Pseudorelapses localized to the spinal cord in patients with previous myelitis presented similarly to true relapses and could only be ruled out by a negative MRI. PMID:27508210

How I manage ibrutinib-refractory chronic lymphocytic leukemia

PubMed Central

2017-01-01

The introduction of the Bruton tyrosine kinase (BTK) inhibitor ibrutinib has dramatically changed the management of chronic lymphocytic leukemia (CLL). Although responses have been durable in the majority of patients, relapses do occur, especially in the high-risk patient population. Most relapses occur as the result of acquired mutations in BTK and PLCG2, which may facilitate success with alternative targeted therapies. As outcomes after ibrutinib relapse have been reported to be poor, specific strategies are needed for this patient population. Here, I discuss the diagnosis and management of ibrutinib-refractory CLL. The focus will be on common clinical scenarios that can be mistaken for relapse and how to accurately determine which patients are relapsing. Because there is no established standard of care, I discuss currently available options for standard therapy and existing clinical data. I also discuss new agents with the potential to be effective in patients refractory to ibrutinib. Finally, I discuss strategies for long-term disease control in this patient population.

This prospective non-interventional study assessed the management of relapsed/refractory CLL after one or two treatments with rituximab, and retreatment with a rituximab-based regimen. An interim analysis was performed at the end of the induction period in 192 evaluable patients. Median age was 72 years [35-89], first relapse (55%), and second relapse (45%). Rituximab administered during first (68%), second (92%), or both treatment lines (20%). R-bendamustine administered in 56% of patients, R-purine analogs (21%), and R-alkylating agents (19%). The overall response rate (ORR) was 74.6%, in favor of R-purine analogs (90%), R-bendamustine (75%), and R-alkylating agents (69%). Lower ORR in Del 17p patients (43%) and third time rituximab (31%). Most frequent adverse events were hematological (23% patients) including neutropenia (11%) and infections (12%); grade 3/4 AEs (23% patients), mainly hematological (18%); death during induction treatment (7%). This first large study focusing on relapsed/refractory CLL patients retreated with rituximab-based regimens is still ongoing.

2018-04-04

Allogeneic hematopoietic cell transplantation (HCT) is a curative option for patients with acute myeloid leukemia (AML) and myelodysplastic syndrome (MDS), but carries a high risk of relapse. This retrospective review evaluates the effectiveness of maintenance azacitidine in high-risk AML and MDS patients to reduce the probability of relapse. Twenty-five patients who received maintenance azacitidine were matched to historical controls in a two-to-one ratio based on diagnosis, donor type, conditioning regimen intensity, and age. Over 90% of patients received myeloablative conditioning. There was no difference in time to hematologic relapse, overall survival, or non-relapse mortality. Maintenance therapy was stopped early in 72% of patients due to graft-versus-host-disease, relapse, infection, and intolerance (13 of 25 patients received less than 4 cycles). There was a trend towards higher toxicity in the azacitidine group. The use of prophylactic azacitidine following myeloablative allogeneic HCT outside a clinical trial cannot be recommended at this time.

Analyses of data from 4 relapse-prevention studies with escitalopram were conducted in order to compare patients with and without residual symptoms with regard to relapse rates and global illness during double-blind, 24-week continuation periods. Clinical Global Impressions-Severity of Illness scores and relapse status in 4 studies published from 2005 to 2007, 1 each in major depressive disorder (MDD), generalized anxiety disorder, social anxiety disorder, and obsessive-compulsive disorder (OCD), were analyzed using mixed-effects model repeated measures as a function of Montgomery-Asberg Depression Rating Scale (MADRS) scores on items 1, 3, and 7 at randomization. All studies showed a statistically significant (P < .0001) standardized effect size of about 0.7 for escitalopram versus placebo, with a number needed to treat approximately 4. Patients with residual symptoms (MADRS score > 0) and without residual symptoms (MADRS score = 0) at the start of continuation treatment were defined by how patients scored on 3 core items of the MADRS: depressed mood (observed), inner or psychic tension, and lassitude. At randomization, patients with a residual symptom were globally more ill than patients without such a symptom. Patients who did not continue active treatment worsened, even if they were initially free of a residual symptom. In contrast, patients who continued receiving escitalopram remained stable or further improved, regardless of residual symptoms or diagnosis. No clear picture emerged regarding whether patients with residual symptoms had a higher relapse rate. The presence of residual symptoms is associated with significantly worse overall illness severity in all 4 diagnostic groups and with a higher (although not significantly) risk of relapse for patients with MDD or OCD. The greatest difference in all of the studies was between patients treated with escitalopram (relapse rates ~ 20%) and placebo (relapse rates of about 50%).

Acute lymphoblastic leukemia (ALL) with a history of central nervous system (CNS) involvement, either at diagnosis or relapse, poses challenges when the decision is made to proceed with allogeneic hematopoietic cell transplantation (alloHCT), as there is no evidence-based consensus on the best peri-transplantation approach to reduce subsequent CNS relapse risk. Here, we retrospectively analyzed outcomes of 87 patients with ALL and a history of CNS involvement who later underwent alloHCT. Patients with pretransplantation CNS involvement had higher risk of CNS relapse after transplantation (2-year CNS relapse: 9.6% versus 1.4%, P < .0001), inferior event-free survival (EFS) (hazard ratio [HR], 1.52; P = .003), and worse overall survival (OS) (HR, 1.55; P = .003) compared with patients without pretransplantation CNS involvement (n = 543). There was no difference in post-transplantation CNS relapse, EFS, or OS among patients presenting with CNS involvement at diagnosis, those with isolated CNS relapse, and those with combined bone marrow and CNS relapse before HCT. Interestingly, neither pretransplantation cranial irradiation, use of total body irradiation-based conditioning, nor post-transplantation prophylactic intrathecal chemotherapy were associated with a reduction of CNS relapse risk after transplantation. Thus, among the patients in the cohort studied, there was no clear benefit of CNS-directed therapy in the peri-transplantation period among patients who had prior CNS involvement and underwent subsequent alloHCT.

Outcome of HIV-infected patients with AIDS-related lymphomas has improved during recent years. However, data on incidence, risk factors, and outcome of relapses in AIDS-related lymphomas after achieving complete remission are still limited. This prospective observational multicenter study includes HIV-infected patients with biopsy- or cytology-proven malignant lymphomas since 2005. Data on HIV infection and lymphoma characteristics, treatment and outcome were recorded. For this analysis, AIDS-related lymphomas patients in complete remission were analyzed in terms of their relapse- free survival and potential risk factors for relapses. In total, 254 of 399 (63.7%) patients with AIDS-related lymphomas reached a complete remission with their first-line chemotherapy. After a median follow up of 4.6 years, 5-year overall survival of the 254 patients was 87.8% (Standard Error 3.1%). Twenty-nine patients relapsed (11.4%). Several factors were independently associated with a higher relapse rate, including an unclassifiable histology, a stage III or IV according to the Ann Arbor Staging System, no concomitant combined antiretroviral therapy during chemotherapy and R-CHOP-based compared to more intensive chemotherapy regimens in Burkitt lymphomas. In conclusion, complete remission and relapse rates observed in our study are similar to those reported in HIV-negative non-Hodgkin lymphomas. These data provide further evidence for the use of concomitant combined antiretroviral therapy during chemotherapy and a benefit from more intensive chemotherapy regimens in Burkitt lymphomas. Modifications to the chemotherapy regimen appear to have only a limited impact on relapse rate. Copyright © 2018 Ferrata Storti Foundation.

AIM: To investigate whether semi-vegetarian diet (SVD) has a preventive effect against relapse of Crohn’s disease (CD) in patients who have achieved remission, who are a high-risk group for relapse. METHODS: A prospective, single center, 2-year clinical trial was conducted. Twenty-two adult CD patients who achieved clinical remission either medically (n = 17) or surgically (n = 5) and consumed an SVD during hospitalization were advised to continue with an SVD and avoid known high-risk foods for inflammatory bowel disease. The primary endpoint was clinical relapse defined as the appearance of active symptoms of CD. Kaplan-Meier survival analysis was used to calculate the cumulative proportion of patients who had a relapse. A 2-year analysis of relapse rates of patients who followed an SVD and those who did not (an omnivorous diet group) was undertaken. RESULTS: SVD was continued by 16 patients (compliance 73%). Remission was maintained in 15 of 16 patients (94%) in the SVD group vs two of six (33%) in the omnivorous group. Remission rate with SVD was 100% at 1 year and 92% at 2 years. SVD showed significant prevention in the time to relapse compared to that in the omnivorous group (P = 0.0003, log rank test). The concentration of C-reactive protein was normal at the final visit in more than half of the patients in remission who were taking an SVD, who maintained remission during the study (9/15; 60%), who terminated follow-up (8/12; 67%), and who completed 2 years follow-up (7/10; 70%). There was no untoward effect of SVD. CONCLUSION: SVD was highly effective in preventing relapse in CD. PMID:20503448

Limited evidence is available on the economic burden of ulcerative colitis (UC) in the UK, particularly relating to the impact of relapse frequency on direct medical costs. This study identifies and assesses medical resource utilization (MRU) and associated direct costs in mild and moderate UC patients in the UK. A retrospective chart review of patients with mild-to-moderate UC diagnosed at least 1 year before the study was performed. From 33 general practitioner (GP) and 34 gastroenterologist sites, charts of the last three UC patients fulfilling the inclusion criteria were reviewed. Descriptive statistics were calculated for MRU and 2011 costs (GB£) by number of relapses. The study population included 201 patients with a mean age of 39.9 years; 44% were women and the mean disease duration was 7.4 years. UC-related costs of each MRU category increased with the number of relapses. Comparing patients without relapse with those with more than two relapses, the mean annual UC-related costs were £14 versus £2556 for hospitalizations; £218 versus £988 for visits (including nurse, GP, specialist, and other visits); £21 versus £1303 for procedures; £17 versus £188 for diagnostics; and £1168 versus £6660 for all-cause total costs. Age, sex, and site of data reporting (GP vs. gastroenterologist) were not associated with MRU or costs. Patients with mild-to-moderate UC incurred considerable costs that increased markedly with the number of relapses. These findings support the importance of maintenance therapies in UC that reduce or prevent relapses. Quantifying the relationship between relapse rate and costs will inform future health economic studies.

The relentless emergence of dapsone resistance amongst M. leprae threatened leprosy control programmes, and increased the relapse rate of patients cured with dapsone monotherapy. The study aimed to analyse the effect on the relapse rate of dapsone-cured multibacillary (MB) leprosy patients, of re-treatment, using a multidrug therapy (MDT) regimen which differed from the WHO recommended regimen. 794 MB leprosy patients who had been released from treatment after dapsone monotherapy were selected, amongst them 657 were re-treated for 1 year using the modified multidrug therapy regimen (mMDT) including rifampicin, clofazimine and dapsone, and 137 patients were observed as control cases. The regimen was well tolerated with good compliance: 620 patients completed re-treatment with mild side effects and a low incidence of leprosy reactions. There was a statistically significant difference between the relapse rates of re-treated and control groups (chi squaredf = 57.44, P < 0.001). Furthermore, the relapses in the re-treated group were significantly more likely to be later than those in the control group (t = 25.62, P < 0.001). Re-treatment with this modified regimen is acceptable and can reduce the risk of early relapse in dapsone-cured patients. The problem of persisters causing late relapse is likely to remain.

This study was to determine the efficacy of vincristine and irinotecan in children with relapsed hepatoblastoma (HB). A total of 10 patients with relapsed HB were enrolled. Three patients were excluded. Patients received irinotecan 50 mg/m(2)/day, day 1-5 and vincristine 1.5 mg/m(2)/day, day 1, repeated every 3 weeks. The maximum cycles were eight. Reevaluation of tumor was performed every two cycles. The primary outcome was the rate of complete resection. Secondary outcomes were event-free survival (EFS) and overall survival (OS). Of the seven patients assessable for response, one patient with normal AFP level showed a progressive disease and withdrew. He finally died 6 months later. Four had PR, all of them underwent a second surgery and achieved complete resection. Two patients had SD, one patient relapsed 6 months after orthotopic liver transplantation and died, the other one undergoing surgery had micro margin positive, he relapsed again but alive. The rate of complete resection was 71.4% (including orthotopic liver transplantation). The 2-year EFS and OS for the whole group were 57.1% (95% CI, 12.7% to 34.2%) and 71.4% (95% CI, 16.39% to 37.4%), respectively. The combination of irinotecan and vincristine has a significant antitumor activity and acceptable toxicity in children with relapsed HB.

A review of 400 clinical records of paracoccidioidomycosis (PCM) patients, 93 with the acute/subacute (AF) and 307 with the chronic form (CF), attended from 1977 to 2011, selected as to the schedule of release for study by the Office of Medical Records at the University Hospital of the Faculdade de Medicina de Botucatu – São Paulo State University – UNESP, was performed to detect cases in relapse. The control of cure was performed by clinical and serological evaluation using the double agar gel immunodiffusion test (DID). In the diagnosis of relapse, DID, enzyme-linked immunosorbent assay (ELISA) and immunoblotting assay (IBgp70 and IBgp43) were evaluated. Out of 400 patients, 21 (5.2%) went through relapse, 18 of them were male and 3 were female, 6∶1 male/female ratio. Out of the 21 patients in relapse, 15 (4.8%) showed the CF, and 6 (6.4%) the AF (p>0.05). The sensitivity of DID and ELISA before treatment was the same (76.1%). DID presented higher sensitivity in pre-treatment (80%) than at relapse (45%; p = 0.017), while ELISA showed the same sensitivity (80% vs 65%; p = 0.125). The serological methods for identifying PCM patients in relapse showed low rates of sensitivity, from 12.5% in IBgp70 to 65.0% in IBgp43 identification and 68.8% in ELISA. The sensitivity of ELISA in diagnosing PCM relapse showed a strong tendency to be higher than DID (p = 0.06) and is equal to IBgp43 (p = 0.11). In sum, prevalence of relapse was not high in PCM patients whose treatment duration was based on immunological parameters. However, the used methods for serological diagnosis present low sensitivity. While more accurate serological methods are not available, we pay special attention to the mycological and histopathological diagnosis of PCM relapse. Hence, direct mycological, cytopathological, and histopathological examinations and isolation in culture for P. brasiliensis must be appropriately and routinely performed when the hypothesis of relapse is considered.

The prognosis for patients multiple myeloma (MM) has improved substantially over the past decade with the development of new, more effective chemotherapeutic agents and regimens that possess a high level of anti-tumor activity. In spite of this important progress, however, nearly all MM patients ultimately relapse, even those who experience a complete response to initial therapy. Management of relapsed MM thus represents a vital aspect of the overall care for patients with MM and a critical area of ongoing scientific and clinical research. This comprehensive manuscript from the International Myeloma Working Group provides detailed recommendations on management of relapsed disease, with sections dedicated to diagnostic evaluation, determinants of therapy, and general approach to patients with specific disease characteristics. In addition, the manuscript provides a summary of evidence from clinical trials that have significantly impacted the field, including those evaluating conventional dose therapies, as well as both autologous and allogeneic stem cell transplantation. Specific recommendations are offered for management of first and second relapse, relapsed and refractory disease, and both autologous and allogeneic transplant. Finally, perspective is provided regarding new agents and promising directions in management of relapsed MM.

During our daily clinical practice using 11C-Choline PET/CT for restaging patients affected by relapsing prostate cancer (rPCa) we noticed an unusual but significant occurrence of hypodense hepatic lesions with a different tracer uptake. Thus, we decided to evaluate the possible correlation between rPCa and these lesions as possible hepatic metastases. We retrospectively enrolled 542 patients diagnosed with rPCa in biochemical relapse after a radical treatment (surgery and/or radiotherapy). Among these, patients with a second tumor or other benign hepatic diseases were excluded. All patients underwent 11C-Choline PET/CT during the standard restaging workup of their disease. We analyzed CT images to evaluate the presence of hypodense lesions and PET images to identify the relative tracer uptake. In accordance to the subsequent oncological history, five clinical scenarios were recognized [Table 1]: normal low dose CT (ldCT) and normal tracer distribution (Group A); evidence of previously unknown hepatic round hypodense areas at ldCT with normal rim uptake (Group B); evidence of previously known hepatic round hypodense areas at ldCT stable over time and with normal rim uptake (Group C); evidence of previously known hepatic round hypodense areas at ldCT, in a previous PET/CT scan, with or without rim uptake and significantly changing over time in terms of size and/or uptake (Group D); evidence of hepatic round hypodense areas at ldCT with or without rim uptake confirmed as prostate liver metastases by histopathology, triple phase ceCT, ce-ultra sound (CEUS) and clinical/biochemical evaluation (Group E). We evaluated the correlation with PSA level at time of scan, rim SUVmax and association with local relapse or non-hepatic metastases (lymph nodes, bone, other parenchyma). Five hundred and forty-two consecutive patients were retrospectively enrolled. In 140 of the 542 patients more than one 11C-choline PET/CT had been performed. A total of 742 11C-Choline PET/CT scans were analyzed. Of the 542 patients enrolled, 456 (84.1%) had a normal appearance of the liver both at ldCT and PET (Group A). 19/542 (3,5%) belonged to Group B, 13/542 (2.4%) to Group C, 37/542 (6.8%) to Group D and 18/542 (3.3%) to Group E. Mean SUVmax of the rim was: 4.5 for Group B; 4.2 for Group C; 4.8 for Group D; 5.9 for Group E. Mean PSA level was 5.27 for Group A, 7.9 for Group B, 10.04 for Group C, 10.01 for Group D, 9.36 for Group E. Presence of positive findings at 11C-Choline PET/CT in any further anatomical area (local relapse, lymph node, bone, other extra hepatic sites) correlated with an higher PSA (p = 0.0285). In both the univariate and multivariate binary logistic regression analyses. PSA, SUVmax of the rim, local relapse, positive nodes were not associated to liver mets (Groups D-E) (p > 0.05). On the contrary, a significant correlation was found between the presence of liver metG (group D-E) and bone lesions (p= 0.00193). Our results indicate that liver metastases in relapsing prostate cancer may occur frequently. The real incidence evaluation needs more investigations. In this case and despite technical limitations, Choline PET/CT shows alterations of tracer distribution within the liver that could eventually be mistaken for simple cysts but can be suspected when associated to high trigger PSA, concomitant bone lesions or modification over time. In this clinical setting an accurate analysis of liver tracer distribution (increased or decreased uptake) by the nuclear medicine physician is, therefore, mandatory.

Vedolizumab (VDZ), an α4β7 anti-integrin antibody, is efficacious in the induction and maintenance of remission in ulcerative colitis (UC) and Crohn's disease (CD). In the GEMINI long-term safety study, enrolled patients received 4-weekly VDZ. Upon completion, patients were switched to 8-weekly VDZ in Australia. The clinical success rate of treatment de-escalation for patients in remission on VDZ has not been described previously. To determine the proportion of patients who relapsed after switching from 4 to 8-weekly VDZ, the mean time to relapse, and the recapture rate when switching back to 8-weekly dosing. This was a retrospective, observational, multicenter study of patients previously recruited into GEMINI long-term safety in Australia. Data on the demographics and biochemical findings were collected. There were 34 patients [23 men, mean age 49.1 (±13.1) years] and their mean disease duration was 17.6 (±8.5) years. The mean 4-weekly VDZ infusion duration was 286.5 (±48.8) weeks. A total of five (15%) patients relapsed on dose-interval increase (4/17 UC, 1/17 CD) at a median duration from dose interval lengthening to flare of 14 weeks (interquartile range=6-25). Eighty percent (4/5) of patients re-entered remission following dose-interval decrease back to 4-weekly. No clinical predictors of relapse could be determined because of the small cohort size. The risk of patients relapsing when switching from 4 to 8-weekly VDZ ∼15% and is similar between CD and UC. Dose-interval decrease recaptures 80% of patients who relapsed. Therapeutic drug monitoring of VDZ may be of clinical relevance.

Objective Schizophrenia (Sz) patients are among the highest utilizers of hospital-based services. Prevention of relapse is in part a treatment goal in order to reduce hospital admissions. However, predicting relapse is a challenge, particularly for payers and disease management firms with only access to claims data. Understandably, such organizations have had little success predicting relapse. A tool that allows payers to identify patients at elevated risk of relapse could facilitate targeted interventions prior to relapse and avoid rehospitalization. In this study, a series of proxy measures of patient instability, calculated from claims data were examined for their utility in identifying Sz patients at elevated risk of relapse. Methods Aetna claims were used to assess the relationship between instability of Sz patients and valence and magnitude of antipsychotic (AP) medication change during a 2-year period. Six proxies of instability including hospital admissions, emergency department visits, medication utilization patterns, and use of outpatient services were identified. Results were replicated using claims data from Truven MarketScan®. Results Patients who switched AP ingredient had the highest overall instability at the point of switch and the second steepest decline in instability following switch. Those who changed to a long-acting injectable AP showed the second highest level of instability and the steepest decrease in instability following the change. Patients augmented with a second AP showed the smallest increase in instability, up to the switch. Results were directionally consistent between the two data sets. Conclusion Using claims-based proxy measures to estimate instability may provide a viable method to better understand Sz patient markers of change in disease severity. Also, such proxies could be used to identify those individuals with the greatest need for treatment modification preventing relapse, improving patient outcomes, and reducing the burden of illness.

Purpose: To review the role of radiotherapy (RTx) alone in patients with Merkel cell carcinoma (MCC). Methods and Materials: The records of 43 patients with MCC treated with RTx alone between 1993 and 2007 at the Westmead and Royal Brisbane/Mater Hospitals, Australia, were reviewed. Multivariate analysis was performed by use of Cox regression analysis. Results: The median age was 79 years (range, 48-91 years) in 19 women (44%) and 24 men (56%). All patients were white, and 5 (12%) had immunosuppression. A majority (56%) underwent irradiation at initial diagnosis, with the remainder (44%) treated in the relapse setting. The medianmore » duration of follow-up was 39 months. The head and neck comprised the most frequently treated site (47%). The median maximum lesion size was 30 mm (range, 5-130 mm). Relapse developed in 60% of patients, with most being out-of-field relapses. The in-field control rate was 75%. Most out-of-field relapses were to visceral organs. Relapse developed outside the irradiated field in 53% of patients. On multivariate analysis, only nodal status (negative nodes vs. nodes present) was significantly associated with relapse-free survival, with p = 0.005 (hazard ratio, 0.25; 95% confidence interval, 0.96-0.663). Overall survival at 2 and 5 years was 58% and 37%, respectively. Conclusions: Patients with MCC treated with RTx have a high likelihood of obtaining in-field control. Doses of 50 to 55 Gy in 20 to 25 fractions are recommended. A minority of patients are cured, with many dying of systemic relapse. Lower dose fractionation schedules (e.g., 25 Gy in 5 fractions) may be considered in patients with a very poor performance status.« less

The objective of this economic model was to estimate the difference in medical costs among patients treated with paliperidone palmitate once-monthly injectable antipsychotic (PP1M) vs placebo, based on clinical event rates reported in the 15-month randomized, double-blind, placebo-controlled, parallel-group study of paliperidone palmitate evaluating time to relapse in subjects with schizoaffective disorder. Rates of psychotic, depressive, and/or manic relapses and serious and non-serious treatment-emergent adverse events (TEAEs) were obtained from the long-term paliperidone palmitate vs placebo relapse prevention study. The total annual medical cost for a relapse from a US payer perspective was obtained from published literature and the costs for serious and non-serious TEAEs were based on Common Procedure Terminology codes. Total annual medical cost differences for patients treated with PP1M vs placebo were then estimated. Additionally, one-way and Monte Carlo sensitivity analyses were conducted. Lower rates of relapse (-18.3%) and serious TEAEs (-3.9%) were associated with use of PP1M vs placebo as reported in the long-term paliperidone palmitate vs placebo relapse prevention study. As a result of the reduction in these clinical event rates, the total annual medical cost was reduced by $7140 per patient treated with PP1M vs placebo. One-way sensitivity analysis showed that variations in relapse rates had the greatest impact on the estimated medical cost differences (range: -$9786, -$4670). Of the 10,000 random cycles of Monte Carlo simulations, 100% showed a medical cost difference <$0 (reduction) for patients using PPIM vs placebo. The average total annual medical differences per patient were -$8321 for PP1M monotherapy and -$6031 for PPIM adjunctive therapy. Use of PP1M for treatment of patients with schizoaffective disorder was associated with a significantly lower rate of relapse and a reduction in medical costs compared to placebo. Further evaluation in the real-world setting is warranted.

Maxillary distraction osteogenesis is a reliable treatment for cleft lip and palate with midfacial retrusion. The purpose of this study was to evaluate the results of long-term follow-up in patients with cleft lip and palate after maxillary distraction osteogenesis and to find clinical factors related to relapse. From February 2002 to June 2008, 21 patients with severe class III malocclusion were treated at our hospital. We performed distraction osteotomy with a rigid external distractor device. The distraction length was more than 15 mm in all patients. Preoperative and postoperative lateral cephalometric radiographs were used for analysis. The sella-nasion-subnasale, sella-nasion-supramentale, and point-A-point-B-nasion (sella-nasion-subnasale-sella-nasion-supramentale) angles were recorded. The timelines for follow-up were preoperatively, after distraction, after consolidation, at 3 years, and once fully grown (5- to 8-year follow-ups). A comparative analysis of clinical factors was performed for the relapsing and nonrelapsing groups. Of the 21 patients, 14 had relapsed. The mean age in the relapsing group was 9.1 years (7 boys and 7 girls) with 9 patients with unilateral cleft palate and 5 c bilateral cleft palate. The mean age in the nonrelapsing group was 11.7 years (4 boys and 3 girls) with 5 patients with unilateral cleft palate and 2 patients with bilateral cleft palate. Despite greater anterior overcorrection, relapse occurred owing to scar tissue retraction and mandibular compensatory hypertrophy. The results suggest that the younger the patient, the more likely relapse will occur.

Relapse and hospital admission are common among, and carry a heavy burden in, patients with schizophrenia and bipolar disorder. The aim of this study was to assess the risk of relapse and hospitalizations in patients with schizophrenia and bipolar disorder at the St Amanuel Mental Specialized Hospital, Addis Ababa, Ethiopia. A hospital-based comparative cross-sectional study was conducted in June 2016. Systematic random sampling technique was used to recruit 521 (260 schizophrenia cases and 261 bipolar disorder cases) study participants. Face-to-face interviews were conducted by trained psychiatry professionals. Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, Text Revision (DSM-IV-TR) criteria and Structured Clinical Interview of DSM-IV (SCID) were used. The risk of relapse and hospitalizations was slightly higher in patients with bipolar disorder than in patients with schizophrenia. A majority of schizophrenic (213 [81.92%]) and bipolar (215 [82.37%]) patients had a history of hospital admission, and 228 (87.69%) schizophrenic and 230 (88.12%) bipolar patients had a history of relapse. Patients who had a history of hospitalizations also had co-occurring substance use disorders compared to those who had no history of hospitalizations for schizophrenia (81.5% vs 37.9%) and bipolar disorder (82.56% vs 38.2%), respectively. Similarly, those patients who had a history of relapse had high comorbid substance use disorders than those who had no history of relapse for both schizophrenia (87.88% vs 47.37%) and bipolar disorder (88.37% vs 47.19%), respectively. It is vital that, in the local context, mental health professionals strengthen their therapeutic relationships with patients and their caregivers. This might enable patients and their caregivers to express their needs and concerns to them, as well as help to plan proper interventions for patients. Attention needs to be given to screening for comorbid substance use disorders in patients with schizophrenia and bipolar disorder, especially in those who have had a history of relapse and hospitalizations.

We performed a retrospective, prognostic analysis of a cohort of patients with epilepsy according to time of relapse after four seizure-free years. Planned withdrawal of antiepileptic drugs (AEDs) and at least 3 years of follow-up after AED discontinuation were performed. The following two groups were assessed: (1) an early relapse (ER) group of patients who experienced recurrence during AED withdrawal and (2) a late relapse (LR) group of patients who experienced recurrence after completion of the AED discontinuation process. After dichotomization, the relapse rate, prognostic factors, and their impacts for each group were compared with those of a group of patients who continued to be seizure-free after AED withdrawal (SF group) using multiple logistic regression analysis. The AED intake mode was also analyzed. Two hundred seventeen (64.6%) of the 336 total patients experienced relapse. One hundred thirty-nine patients (41.4%) and 78 patients (23.2%) were included in the LR and ER groups, respectively. Symptom duration >120 months showed the strongest negative prognostic impact as demonstrated by the 4.7-fold higher risk of recurrence in the ER group compared with the SF group. Additional factors with a negative prognostic impact included an age at epilepsy onset of ≤20 years and the presence of localization-related epilepsy. No reliable predictor between the SF and LR groups was revealed. After exclusion of the SF group, post hoc analysis according to age at epilepsy onset and symptom duration showed that the above-mentioned negative prognostic factors significantly affected the relapse patterns of the LR and ER groups. The results suggest that longer symptom duration, which could be associated with intrinsic reactivation of epilepsy, is the strongest negative prognostic factor for relapse. Relapse after AED withdrawal in prolonged follow-up of seizure-free patients is one aspect of the natural history of epilepsy. © 2016 The Authors.

IGF2 is a tumor suppressor gene at locus 11p15. Many hepatoblastomas have loss of heterozygosity (LOH) at this locus. Earlier studies have not demonstrated any association between LOH and prognosis. Aim of the study was to evaluate the prognostic significance of LOH at 11p15.5 in hepatoblastomas. DNA was isolated from normal liver and tumor tissue in 20 patients with hepatoblastoma. PCR was performed and cases were classified as LOH present, absent or non-informative. Patients' follow-up data was analyzed using Fischer's exact test and Kaplan-Meier survival analysis for relapse-free survival (RFS) in relation to LOH. Ethical clearance was obtained from the institutional ethics board. All cases were informative for at least one microsatellite marker used. 4 of the 20 cases (20%) had LOH at 11p15.5. One patient died in the immediate postoperative period. 5 of 19 patients relapsed (26%). Of 4 patients who had LOH, 3 (75%) relapsed, the time to relapse being 7, 7 and 9 months, respectively. Of the 15 cases without LOH, 2 (13.3%) relapsed. 4 patients had mixed epithelial and mesenchymal histology; 3 of them had LOH. The 2 groups with and without LOH were well matched. The RFS for patients with LOH (n=4) was 13% (mean survival time [MST]: 8.7 months; 95CI 6.7-10.7), while the RFS for cases without LOH (n=15) was 75% (MST: 100.7 months; 95CI 74.5-126.8). Mixed epithelial and mesenchymal histology is more frequently associated with LOH on chromosome 11p15.5 than pure epithelial histology. LOH on chromosome 11p15.5 is associated with a significantly increased incidence of relapse and a significantly shorter relapse-free survival in patients with hepatoblastoma. The risk of relapse is higher and the RFS lower both in standard-risk and high-risk patients with hepatoblastoma if they demonstrate the presence of LOH at 11p15.5. © Georg Thieme Verlag KG Stuttgart · New York.

It is not clear whether patient's psycho-education enhances compliance to antipsychotic treatments and reduces the number of relapses. Here we investigated the impact of a new psycho-educational program (SOLEDUC) on the one- and two-years rate of relapse (primary outcome measure) and a number of clinical assessments (secondary outcome measures). This was a multicentric French clinical trial (51 centers) of Phase IV, open, controlled, randomized, consisting in two parallel groups: the Soleduc group (N=111) and the control group (N=109). All subjects received a variable dose over the 2-year period of the same antipsychotic drug (amisulpride). Soleduc consisted of a 7-session program (1h per session), presented three times (at baseline, 6-months and 12-months). Patients in the control group received a non-specific psychosocial training for an equivalent period of time. The models of Andersen-Gill (AG) and Prentice, Williams and Peterson (PWP) were used to analyze relapses. Patients in the Soleduc group attended 14.8+/-6.1 sessions (mean+/-SD), including 17 patients who never attended a session. Intent to treat analysis showed less patients relapsing in the Soleduc group as compared to the control group (21.6% versus 28.4% after 1 year and 84.4% versus 90.8% after 2years), but the differences were not statistically significant. Relapse risk was significantly reduced for patients who followed at least 7 modules (p=0.015 AG-test; p<0.001 PWP-test). In conclusion, no significant differences in relapse rates were found between patients attending the Soleduc program and the control group. Attendance of at least 7 out of 21 program sessions was required to see a modest, but significant two-year relapse prevention in schizophrenia. Other well designed studies are required to evaluate the medical impact of patient's education programs.

Therapeutic intervention programs for somatic symptom disorder (SSD) show only small-to-moderate effect sizes. These effects are partly explained by the motivational problems of SSD patients. Hence, fostering treatment motivation could increase treatment success. One central aspect in SSD patients might be damage to motivation because of symptomatic relapses. Consequently, the aim of the present study was to investigate associations between motivational relapse struggle and therapeutic outcome in SSD patients. We assessed 84 inpatients diagnosed with SSD in the early, middle and late stages of their inpatient treatment. The maintenance subscale of the University of Rhode Island Change Assessment-Short (URICA-S) was applied as a measure to assess motivational relapse struggle. Additionally, patients completed measures of treatment outcome that focus on clinical symptoms, stress levels and interpersonal functioning. The results from multiple regression analyses indicate that higher URICA-S maintenance scores assessed in early stages of inpatient treatment were related to more negative treatment outcomes in SSD patients. SSD patients with ambivalent treatment motivation may fail in their struggle against relapse over the course of therapy. The URICA-S maintenance score assessed at therapy admission facilitated early identification of SSD patients who are at greater risk of relapse. Future studies should incorporate randomized controlled trials to investigate whether this subgroup could benefit from motivational interventions that address relapse.

Cytarabine is the backbone of most chemotherapeutic regimens for acute myeloid leukemia (AML), yet the optimal dose for salvage therapy of refractory or relapsed AML (RR-AML) has not been established. Very high dose single-agent cytarabine at 36 g/m(2) (ARA-36) was previously shown to be effective and tolerable in RR-AML. In this retrospective analysis, we aim to describe the toxicity and efficacy of ARA-36 as salvage therapy for patients with AML who are primary refractory to intensive daunorubicin-containing induction or those relapsing after allogeneic stem cell transplant (alloSCT). Fifteen patients, median age 53 years, were included in the analysis. Six patients were treated for induction failure, one had resistant APL, and eight relapsed after alloSCT. Complete remission was achieved in 60% of patients. Surviving patients were followed for a median of 8.5 months. One-year overall survival was 54% (95% CI 30%-86%), and relapse rate from remission (n = 9) was 56%. Grade III/IV pulmonary, infectious, ocular and gastrointestinal toxicities occurred in 26%, 20%, 20% and 20% of patients respectively. Salvage therapy with ARA-36 regimen for RR-AML has considerable efficacy with manageable toxicity in patients with induction failure or post-transplant relapse. Overall survival in these high-risk patients still remains poor. Copyright © 2015 John Wiley & Sons, Ltd.

Donor lymphocyte infusions (DLI) are an effective treatment for relapsed chronic myeloid leukemia (CML) after allogeneic stem cell transplantation (alloSCT). Leukemia resistance and secondary graft-versus-host disease (GVHD) are major obstacles to success with DLI. The aim of this study was to identify pre-DLI factors associated with prolonged survival in remission without secondary GVHD. We retrospectively analyzed 500 patients treated with DLI for CML relapse (16% molecular, 30% cytogenetic, and 54% hematological) after alloSCT. The overall probabilities of failure- and secondary GVHD-free survival (FGFS) were 29% and 27% at 5 and 10 years after DLI, respectively. The type of relapse was the major factor influencing FGFS (40% for molecular and/or cytogenetic relapse and 20% for hematological relapse at 5 years, P < .001). Chronic GVHD before DLI and an interval <1 year between alloSCT and first DLI were independently associated with inferior FGFS in patients with molecular and/or cytogenetic relapse. Consequently, FGFS was 13%, 35%, to 56% at 5 years in patients with 2, 1, and 0 adverse features, respectively. In patients with hematological relapse, independent adverse prognostic factors for FGFS were initial dose of CD3(+) cells ≥ 50 × 10(6)/kg, donor-recipient sex mismatch, and chronic GVHD before DLI. FGFS was 0%, 17%, 33%, to 37% in patients with 3, 2, 1, and 0 adverse features, respectively. The probability of survival in remission without secondary GVHD was highest (>50% at 5 years) when DLI were given beyond 1 year from alloSCT for molecular and/or cytogenetic CML relapse that was not preceded by chronic GVHD.

Few randomized trials have been conducted in children with relapsed/refractory neuroblastoma and data about outcomes including progression-free survival (PFS) in these patients are scarce. A meta-analysis of three phase II studies of children with relapsed/refractory neuroblastoma conducted in Europe (temozolomide, topotecan-vincristine-doxorubicin and topotecan-temozolomide) was performed. Individual patient data with extended follow-up were collected from the trial databases after publication to describe trial outcomes (response rate, clinical benefit ratio, duration of treatment, PFS, and overall survival [OS]). Characteristics of subjects with relapsed/refractory neuroblastoma were compared. Data from 71 children and adolescents with relapsed/refractory neuroblastoma were collected. Response definitions were not homogeneous in the three trials. Patients were on study for a median of 3.5 months (interquartile range [IQR] 1.9-6.2). Of those, 35.2% achieved a complete or partial response, 26.3% experienced a response after more than two cycles, and 23.9% received more than six cycles. Median PFS from study entry for all, refractory, and relapsed patients was 6.4 ± 1.0, 12.5 ± 6.8, and 5.7 ± 1.0 months, respectively (P = 0.006). Median OS from study entry for all, refractory, and relapsed patients was 16.1 ± 4.3, 27.9 ± 20.2, and 11.0 ± 1.6 months, respectively (P = 0.03). Baseline data for response rate, clinical benefit ratio, duration of treatment, PFS, and OS were provided. Two subpopulations (relapsed/refractory) were clearly distinct and should be included in the interpretation of all trials. These results should help informing the design of forthcoming studies in relapsed/refractory neuroblastoma. © 2016 Wiley Periodicals, Inc.

To evaluate the efficacy of etanercept vs placebo in preventing relapses of uveitis in patients taking methotrexate with control of uveitis and whose methotrexate dosage was being tapered. Patients with chronic or recurrent noninfectious uveitis with inflammation controlled by low-dose methotrexate were randomized to either the drug or placebo group in a double-masked manner, given a methotrexate taper schedule, and followed for 24 weeks. The main outcome measures were control of inflammation, visual acuity, and adverse reactions. Data were analyzed both as an attempt-to-treat analysis and an analysis only of those patients who completed the study. A total of 20 patients were randomized to the drug and placebo groups. Relapse of uveitis occurred in 3 of 10 patients in the treatment group and 5 of 10 patients in the control group. Two patients in the treatment group withdrew prematurely from the study due to adverse effects. There was no significant difference between the treatment and placebo groups with regard to the rate of relapse and the final visual acuity. No patient suffered from any irreversible, long-term morbidity or mortality. Etanercept has no significant efficacy over placebo in preventing relapses of uveitis in patients being tapered from methotrexate.

Purpose: To assess the effect of radiotherapy (RT) dose and volume on relapse patterns in patients with Stage I-III Merkel cell carcinoma (MCC). Patients and Methods: This was a retrospective analysis of 112 patients diagnosed with MCC between January 2000 and December 2005 and treated with curative-intent RT. Results: Of the 112 evaluable patients, 88% had RT to the site of primary disease for gross (11%) or subclinical (78%) disease. Eighty-nine percent of patients had RT to the regional lymph nodes; in most cases (71%) this was for subclinical disease in the adjuvant or elective setting, whereas 21 patients (19%)more » were treated with RT to gross nodal disease. With a median follow-up of 3.7 years, the 2-year and 5-year overall survival rates were 72% and 53%, respectively, and the 2-year locoregional control rate was 75%. The in-field relapse rate was 3% for primary disease, and relapse was significantly lower for patients receiving {>=}50Gy (hazard ratio [HR] = 0.22; 95% confidence interval [CI], 0.06-0.86). Surgical margins did not affect the local relapse rate. The in-field relapse rate was 11% for RT to the nodes, with dose being significant for nodal gross disease (HR = 0.24; 95% CI, 0.07-0.87). Patients who did not receive elective nodal RT had a much higher rate of nodal relapse compared with those who did (HR = 6.03; 95% CI, 1.34-27.10). Conclusion: This study indicates a dose-response for subclinical and gross MCC. Doses of {>=}50Gy for subclinical disease and {>=}55Gy for gross disease should be considered. The draining nodal basin should be treated in all patients.« less

To determine the incidence of relapse in patients with lung tuberculosis and its associated risk factors. A follow up study was conducted with 237 patients who were cured after receiving treatment in rural medical facilities from the State of Chiapas. The global incidence of relapse was 1.04 cases per 100 month/person. The risk factors for relapse were lack of knowledge about treatment (OR = 2.28; 95% CI = 1.06-4.89); drug adverse effects (OR = 2.78; 95% CI = 1.31-5.90), waiting time for more than 15 minutes to receive medical care (OR = 3.07; 95% CI = 1.06-12.94) and lack of medical supervision (OR = 4.77; 95% CI = 1.30-17.41). Most of the risk factors for relapse are susceptible to modification and are related with the quality of medical care provided to lung tuberculosis patients.

Purpose: To report the clinical course of adolescents with medulloblastoma, with specific emphasis on prognosis and pattern of relapse. Methods and Materials: We retrospectively studied the clinical course and outcomes of children aged 10-20 years with medulloblastoma, treated at centers throughout Canada between 1986 and 2003. To better assess time to relapse, a cohort of patients aged 3-20 years at diagnosis was generated. Results: A total of 72 adolescents were analyzed. Five-year overall survival and event-free survival rates were 78.3% {+-} 5.4% and 68.0% {+-} 6.2%, respectively. Late relapses occurred at a median of 3.0 years (range, 0.3-6.8 years). Inmore » univariate analysis, conventional risk stratification and the addition of chemotherapy to craniospinal radiation did not have prognostic significance. Female patients had improved overall survival (p = 0.007). Time to relapse increased with age in a linear fashion. After relapse, patients faired poorly regardless of treatment modality. Patients who did not receive chemotherapy initially had improved progression-free survival at relapse (p 0.05). Conclusions: Our study suggests that adolescents with medulloblastoma might have a unique prognosis and pattern of relapse, dissimilar to those in younger children. They might benefit from different risk stratifications and prolonged follow-up. These issues should be addressed in future prospective trials.« less

A simple risk scoring system for prediction of relapse after inpatient alcohol treatment.

Pedersen, Mads Uffe; Hesse, Morten

2009-01-01

Predicting relapse after alcoholism treatment can be useful in targeting patients for aftercare services. However, a valid and practical instrument for predicting relapse risk does not exist. Based on a prospective study of alcoholism treatment, we developed the Risk of Alcoholic Relapse Scale (RARS) using items taken from the Addiction Severity Index and some basic demographic information. The RARS was cross-validated using two non-overlapping samples, and tested for its ability to predict relapse across different models of treatment. The RARS predicted relapse to drinking within 6 months after alcoholism treatment in both the original and the validation sample, and in a second validation sample it predicted admission to new treatment 3 years after treatment. The RARS can identify patients at high risk of relapse who need extra aftercare and support after treatment.

Purpose: The study was designed to determine whether response-based therapy improves outcomes in intermediate-risk Hodgkin lymphoma. We examined patterns of first relapse in the study. Patients and Methods: From September 2002 to July 2010, 1712 patients <22 years old with stage I-IIA with bulk, I-IIAE, I-IIB, and IIIA-IVA with or without doxorubicin, bleomycin, vincristine, etoposide, prednisone, and cyclophosphamide were enrolled. Patients were categorized as rapid (RER) or slow early responders (SER) after 2 cycles of doxorubicin, bleomycin, vincristine, etoposide, prednisone, and cyclophosphamide (ABVE-PC). The SER patients were randomized to 2 additional ABVE-PC cycles or augmented chemotherapy with 21 Gy involved field radiationmore » therapy (IFRT). RER patients were stipulated to undergo 2 additional ABVE-PC cycles and were then randomized to 21 Gy IFRT or no further treatment if complete response (CR) was achieved. RER without CR patients were non-randomly assigned to 21 Gy IFRT. Relapses were characterized without respect to site (initial, new, or both; and initial bulk or initial nonbulk), and involved field radiation therapy field (in-field, out-of-field, or both). Patients were grouped by treatment assignment (SER; RER/no CR; RER/CR/IFRT; and RER/CR/no IFRT). Summary statistics were reported. Results: At 4-year median follow-up, 244 patients had experienced relapse, 198 of whom were fully evaluable for review. Those who progressed during treatment (n=30) or lacked relapse imaging (n=16) were excluded. The median time to relapse was 12.8 months. Of the 198 evaluable patients, 30% were RER/no CR, 26% were SER, 26% were RER/CR/no IFRT, 16% were RER/CR/IFRT, and 2% remained uncategorized. The 74% and 75% relapses involved initially bulky and nonbulky sites, respectively. First relapses rarely occurred at exclusively new or out-of-field sites. By contrast, relapses usually occurred at nodal sites of initial bulky and nonbulky disease. Conclusion: Although response-based therapy has helped define treatment for selected RER patients, it has not improved outcome for SER patients or facilitated refinement of IFRT volumes or doses.« less

Following promising results to increase survival and reduce treatment burden in intracranial non-germinomatous germ cell tumors (NGGCTs), we conducted a European study using dose-intense chemotherapy followed by risk-adapted radiotherapy. All patients received 4 courses of cisplatin/etoposide/ifosfamide. Non-metastatic patients then received focal radiotherapy only (54 Gy); metastatic patients received 30 Gy craniospinal radiotherapy with 24 Gy boost to primary tumor and macroscopic metastatic sites. Patients with localized malignant NGGCT (n = 116) demonstrated 5-year progression-free survival (PFS) and overall survival (OS) of 0.72 ± 0.04 and 0.82 ± 0.04, respectively. Primary tumor sites were: 67 pineal, 35 suprasellar, 5 bifocal, 9 others. One patient died postsurgery in clinical remission; 3 patients progressed during treatment and 27 (23%) relapsed afterward. Fourteen were local, 6 combined, and 7 distant relapses (outside radiation field). Seventeen of the 27 relapsed patients died of disease. Patients with metastatic disease (n = 33) demonstrated 5-year PFS and OS of 0.68 ± 0.09 and 0.75 ± 0.08, respectively; 1 patient died following progression on treatment and 9 (27%) relapsed afterward (5 local, 1 combined, 3 distant). Only one metastatic patient with recurrence was salvaged. Multivariate analysis identified diagnostic alpha-fetoprotein level (serum and/or cerebrospinal fluid level >1000 ng/mL, 19/149 patients, of whom 11 relapsed; P < 0.0003) and residual disease following treatment, including after second-look surgery (n = 52/145 evaluable patients, 26 relapsed; P = 0.0002) as significant prognostic indicators in this cohort. In localized malignant NGGCT, craniospinal radiotherapy could be avoided without increased relapses outside the radiotherapy field. Chemotherapy and craniospinal radiotherapy remain the gold standard for metastatic disease. © The Author(s) 2017. Published by Oxford University Press on behalf of the Society for Neuro-Oncology.

Paclitaxel targets VEGF-mediated angiogenesis in ovarian cancer treatment

PubMed Central

Ai, Bin; Bie, Zhixin; Zhang, Shuai; Li, Ailing

2016-01-01

Ovarian cancer is one of the gynecologic cancers with the highest mortality, wherein vascular endothelial growth factor (VEGF) is involved in regulating tumor vascularization, growth, migration, and invasion. VEGF-mediated angiogenesis in tumors has been targeted in various cancer treatments, and anti-VEGF therapy has been used clinically for treatment of several types of cancer. Paclitaxel is a natural antitumor agent in the standard front-line treatment that has significant efficiency to treat advanced cancers, including ovarian cancer. Although platinum/paclitaxel-based chemotherapy has good response rates, most patients eventually relapse because the disease develops drug resistance. We aim to review the recent advances in paclitaxel treatment of ovarian cancer via antiangiogenesis. Single-agent therapy may be used in selected cases of ovarian cancer. However, to prevent drug resistance, drug combinations should be identified for optimal effectiveness and existing therapies should be improved. PMID:27648354

Treatment of symptoms and signs beyond the expanded disability status scale remains a major target in multiple sclerosis. QualiCOP was an observational, non-interventional, open-label study conducted at 170 sites in Germany. Of the 754 enrolled patients, 96 % had relapsing-remitting multiple sclerosis (MS) and were either disease-modifying therapy naïve (de novo, n = 481) or previously treated (n = 237) with once-daily, subcutaneous 20-mg/mL glatiramer acetate (GA). Assessments of relapse rate, disease progression, overall functioning, quality of life (QoL), cognition, fatigue, and depression were performed over 24 months. GA treatment over 24 months was associated with reduced annual relapse rate for previously treated (from 0.98 to 0.54 relapses) and de novo (from 0.81 to 0.48 relapses) patients. Multiple Sclerosis Functional Composite scores showed slight improvement in both cohorts (all p < 0.01). Paced Auditory Serial Addition Test and Multiple Sclerosis Inventory Cognition scale scores showed robust improvement in cognition among previously treated and de novo cohorts (all p < 0.001). General Depression Scale scores showed significantly reduced depressive symptoms (p < 0.001). Disease severity, fatigue, and QoL were stable over the observational period. These real-world findings suggest that patients with MS show benefit from GA treatment in important QoL parameters beyond standard measures of relapse and disease severity.

We compared two regimens with respect to their ability to prolong disease-free survival in 506 children and adolescents with acute lymphocytic leukemia. All responders to induction therapy were randomized to treatment with 2400 rad of cranial irradiation plus intrathecal methotrexate or to treatment with intermediate-dose methotrexate plus intrathecal methotrexate, as prophylaxis for involvement of the central nervous system and other sanctuary areas. Patients were then treated with a standard maintenance regimen. Complete responders were stratified into either standard-risk or increased-risk groups on the basis of age and white-cell count at presentation. Among patients with standard risk, hematologic relapses occurred inmore » 9 of 117 given methotrexate and 24 of 120 given irradiation (P less than 0.01). The rate of central-nervous-system relapse was higher in the methotrexate group (23 of 117) than in the irradiation group (8 of 120) (P . 0.01). Among patients with increased risk, radiation offered greater protection to the central nervous system than methotrexate (P . 0.03); there was no difference in the rate of hematologic relapse. In both risk strata the frequency of testicular relapse was significantly lower in the methotrexate group (1 patient) than the radiation group (10 patients) (P . 0.01). Methotrexate offered better protection against systemic relapse in standard-risk patients and better protection against testicular relapse overall, but it offered less protection against relapses in the central nervous system than cranial irradiation.« less

Use of Cox's Cure Model to Establish Clinical Determinants of Long-Term Disease-Free Survival in Neoadjuvant-Chemotherapy-Treated Breast Cancer Patients without Pathologic Complete Response.

In prognostic studies for breast cancer patients treated with neoadjuvant chemotherapy (NAC), the ordinary Cox proportional-hazards (PH) model has been often used to identify prognostic factors for disease-free survival (DFS). This model assumes that all patients eventually experience relapse or death. However, a subset of NAC-treated breast cancer patients never experience these events during long-term follow-up (>10 years) and may be considered clinically "cured." Clinical factors associated with cure have not been studied adequately. Because the ordinary Cox PH model cannot be used to identify such clinical factors, we used the Cox PH cure model, a recently developed statistical method. This model includes both a logistic regression component for the cure rate and a Cox regression component for the hazard for uncured patients. The purpose of this study was to identify the clinical factors associated with cure and the variables associated with the time to recurrence or death in NAC-treated breast cancer patients without a pathologic complete response, by using the Cox PH cure model. We found that hormone receptor status, clinical response, human epidermal growth factor receptor 2 status, histological grade, and the number of lymph node metastases were associated with cure.

Burden of a multiple sclerosis relapse: the patient's perspective.

Relapses are a common feature of relapsing-remitting multiple sclerosis (RRMS) and increasing severity has been shown to be associated with higher healthcare costs, and to result in transient increases in disability. Increasing disability likely impacts work and leisure productivity, and lowers quality of life. The objective of this study was to characterize from the patient's perspective the impact of a multiple sclerosis (MS) relapse in terms of the economic cost, work and leisure productivity, functional ability, and health-related quality of life (HR-QOL), for a sample of patients with RRMS in the US treated with immunomodulatory agents. A cross-sectional, web-based, self-report survey was conducted among members of MSWatch.com, a patient support website now known as Copaxone.com. Qualified respondents in the US had been diagnosed with RRMS and were using an immunomodulatory agent. The survey captured costs of RRMS with questions about healthcare resource utilization, use of community services, and purchased alterations and assistive items related to MS. The Work and Leisure Impairment instrument and the EQ-5D were used to measure productivity losses and HR-QOL (health utility), respectively. The Goodin MS neurological impairment questionnaire was used to measure functional disability; questions were added about relapses in the past year. Of 711 qualified respondents, 67% reported having at least one relapse during the last year, with a mean of 2.2 ± 2.3 relapses/year. Respondents who experienced at least one relapse had significantly higher mean annual direct and indirect costs compared with those who did not experience a relapse ($US38 458 vs $US28 669; p = 0.0004) [year 2009 values]. Direct health-related costs accounted for the majority of the increased cost ($US5201; 53%) and were mainly due to increases in hospitalizations, medications, and ambulatory care. Indirect costs, including informal care and productivity loss, accounted for the additional 47% of increased cost ($US4588). Accounting for the mean number of relapses associated with these increased costs, the total economic cost of one relapse episode could be estimated at about $US4449, exclusive of intangible costs. The mean self-reported Expanded Disability Status Scale (EDSS) score, derived from the Goodin MS questionnaire, was significantly higher with relapse than with a clinically stable state (EDSS 4.3 vs 3.7; p < 0.0001), while the mean health utility score was significantly lower with relapse compared with a clinically stable state (0.66 vs 0.75; p = 0.0001). The value of these intangible costs of relapse can be estimated at $US5400. The overall burden (direct, indirect, and intangible costs) of one relapse in patients treated with immunomodulatory agents is therefore estimated conservatively at $US9849. This study shows that from a patient's perspective an MS relapse is associated with a significant increase in the economic costs as well as a decline in HR-QOL and functional ability.

Core-binding factor acute myeloid leukaemia (CBF AML) defined by t(8;21)(q22;q22) or inv(16)(p13q22)/t(16;16)(p13;q22) has a favourable prognosis, however 30-40% of patients still relapse after chemotherapy. We sought to evaluate risk factors for relapse in a de novo CBF AML cohort. A retrospective review of patients from 4 Australian tertiary centres from 2001-2012, comprising 40 t(8;21) and 30 inv(16) AMLs. Multivariate analysis identified age (p=0.032) and WCC>40 (p=0.025) as significant predictors for inferior OS and relapse respectively. Relapse risk was higher in the inv(16) group vs the t(8;21) group (57% vs 18%, HR 4.31, 95% CI: 1.78-10.42, p=0.001). Induction therapy had no bearing on OS or relapse free survival (RFS) however, consolidation treatment with >3 cycles of intermediate/high dose cytarabine improved OS (p=0.035) and relapse-free survival (RFS) (p=0.063). 5 patients demonstrated post-treatment stable q PCR positivity without relapse. (1)>3 consolidation cycles of intermediate/ high-dose cytarabine improves patient outcomes. (2)Age and inv(16) CBF AML subtype are predictors of inferior OS and RFS respectively.

Limited data exist on the costs of care of patients with multiple sclerosis (MS) in low- to middle-income nations. The purpose of this study was to describe the economic burden associated with care of Mexican patients with relapsing-remitting MS in a representative sample of the largest institution of the Mexican public healthcare system. We analysed individual data of 492 patients (67% women) with relapsing-remitting MS registered from January 2009 to February 2011 at the Mexican Social Security Institute. Direct costs were measured about the use of diagnostic tests, disease-modifying therapies (DMTs), symptoms control, medical consultations, relapses, intensive care and rehabilitation. Four groups were defined according to DMT alternatives: (1) interferon beta (IFNβ)-1a, 6 million units (MU); (2) IFNβ-1a, 12MU; (3) IFNβ-1b, 8MU; and (4) glatiramer acetate. All patients received DMTs for at least 1 year. The most frequently used DMT was glatiramer acetate (45.5%), followed by IFNβ-1a 12MU (22.6%), IFNβ-1b 8MU (20.7%), and IFNβ-1a 6MU (11.2%). The mean cost of a specialised medical consultation was €74.90 (US $107.00). A single relapse had a mean total cost of €2,505.97 (US $3,579.96). No differences were found in annualised relapse rates and costs of relapses according to DMT. However, a significant difference was observed in total annual costs according to treatment groups (glatiramer acetate being the most expensive), mainly due to differences in unitary costs of alternatives. From the public institutional perspective, when equipotent DMTs are used in patients with comparable characteristics, the costs of DMTs largely determine the total expenses associated with care of patients with relapsing-remitting MS in a middle-income country.

To describe relapsed B-cell lymphoma or leukemia in children/adolescents treated with a "Lymphomes Malins B" regimen and their outcome and to identify prognostic factors for survival, we studied relapses in the LMB89, 96 and 2001 studies of the Société Française d'Oncologie Pédiatrique (Société Française des Cancers de l'Enfant). Therapeutic guidelines at relapse were to obtain a second complete remission and to consolidate the remission with high-dose chemotherapy followed by autologous stem-cell transplantation. Between July 1989 and March 2007, 67 patients of 1322 (5%) relapsed: 57 had Burkitt lymphoma and 10 had large-cell histology. Three patients were initially treated in risk group A, 41 in group B and 23 in group C. Thirty-three patients had a relapse in one site (15 in the central nervous system) and 34 at multiple sites. Sixty-five patients received salvage chemotherapy and 33 achieved complete remission. Forty-one patients also received high-dose chemotherapy followed by autologous (n=33) or allogeneic (n=8) transplantation. With a median follow-up of 6.4 years, the 5-year survival rate was 29.9%. Nineteen patients were still alive, all but one (group A) received consolidation treatment. Multivariate analysis showed the following factors to be significantly associated with better survival: relapse at one site (P=0.0006), large-cell histology (P=0.012), initial prognostic group A or B with lactate dehydrogenase level below twice the normal value (P=0.005), and time to relapse more than 6 months (P=0.04).

We studied isolates from 73 patients hospitalized with typhoid fever in Lima, Peru. Of these 73 patients, 11 (15%) suffered a clinical relapse, with fever and positive blood cultures, within 3 months of their original illness. Using plasmids as epidemiologic markers, we found that three patients who subsequently relapsed were initially infected with more than one strain of Salmonella typhi. There was a highly significant association between relapse and isolation of a strain containing either a 24- or a 38-kilobase plasmid at the time of the original infection; however, we were unable to show any evidence of homology between these two plasmids. Our data indicate that infection with multiple strains is not uncommon in this endemic area and suggest that relapse may be partly strain dependent. Images PMID:2821064

Cladribine tablets: in relapsing-remitting multiple sclerosis.

Muir, Victoria J; Plosker, Greg L

2011-03-01

Cladribine, an immunosuppressant that selectively reduces peripheral lymphocyte levels, has potential as an oral therapy for relapsing-remitting multiple sclerosis. An oral (tablet) formulation is being investigated in clinical trials. In the large, well designed, phase III CLARITY trial, short-course treatment with oral cladribine (cumulative dose of 3.5 or 5.25 mg/kg) resulted in a significantly greater reduction in annualized relapse rates at 96 weeks compared with placebo in patients with relapsing-remitting multiple sclerosis. Improvements in the annualized relapse rate with oral cladribine were independent of key baseline patient characteristics which included age, sex, previous treatment with disease-modifying drugs and the number of relapses in the previous 12 months. In addition, a significantly higher proportion of patients were relapse-free at 96 weeks and there were significant reductions in the risk of 3-month sustained progression of disability in cladribine recipients compared with placebo recipients. The mean numbers of brain lesions on magnetic resonance imaging were also significantly reduced with cladribine compared with placebo in the CLARITY trial. Lymphocytopenia, herpes zoster infections and neoplasms (including malignancies) were more common in cladribine than placebo recipients.

Antithyroid drugs are effective in restoring euthyroidism in Graves' disease, but many patients experience relapse after withdrawal. Prevention of recurrence would therefore be a desirable goal. In a prospective study, patients with successful outcome of 12 to 15 months antithyroid drug therapy were stratified for risk factors and randomly assigned to receive levothyroxine in a variable thyrotropin (TSH)-suppressive dose for 2 years or no treatment. The levothyroxine group was randomized to continue or discontinue levothyroxine after 1 year. End points included relapse of overt hyperthyroidism. Of 346 patients with Graves' disease enrolled 225 were euthyroid 4 weeks after antithyroid drug withdrawal and were randomly assigned to receive levothyroxine (114 patients) or no treatment (controls, 111 patients). Of those not randomized, 39 patients showed early relapse within 4 weeks, 61 endogenous TSH suppression, 7 TSH elevation, and 14 had to be excluded. Dropout rate during the study were 13.3%. Kaplan-Meier analyses showed relapse rates to be similar in the levothyroxine group (20% after 1 year, 32% after 2 years) and the randomized controls (18%, 24%), whereas relapses were significantly more frequent in the follow-up group of patients with endogenously suppressed TSH (33%, 49%). Levothyroxine therapy did not influence TSH-receptor antibody, nor did it reduce goiter size. The best prognostic marker available was basal TSH determined 4 weeks after withdrawal of antithyroid drugs (posttreatment TSH). The study demonstrates that levothyroxine does not prevent relapse of hyperthyroidism after successful restoration of euthyroid function by antithyroid drugs and characterizes posttreatment TSH as a main prognostic marker.

Between April 1969 and December 1974, 111 consecutive surgically staged I A and II A patients with supradiaphragmatic Hodgkin's disease were treated at the Joint Center for Radiation Therapy. Patients received 3600 to 4400 rad to mantle and para-aortic--splenic pedicle regions. Median follow-up was 56 months. Fourteen patients developed relapsing Hodgkin's disease and three patients died of possible treatment-related causes, two with acute myocardial infarctions and one with radiation pneumonitis. Patients with mediastinal enlargement greater than one third of the chest diameter have a significantly higher risk (p < 0.01) of developing relapse (9 of 18) than patients with lessermore » or no mediastinal disease (5 of 93). Of the 18 patients with large mediastinal disease, six relapsed in the mediastinum and two in the lung. There continue to be no pelvic extensions in the entire group. There is a 92% relapse-free and 97% overall survival in the 93 patients without extensive mediastinal disease. We continue to recommend mantle and para-aortic--splenic pedicle irradiation for these patients. In view of the large number of relapses in patients with extensive mediastinal disease, we are now treating this subgroup of patients with MOPP chemotherapy in addition to mantle and para-aortic irradiation.« less

Previous research has yielded conflicting data as to whether the natural history of inflammatory bowel disease follows a seasonal pattern. The purpose of this study was (1) to determine whether the frequency of onset and relapse of inflammatory bowel disease follows a seasonal pattern and (2) to establish a model to predict the frequency of onset, relapse, and severity of inflammatory bowel disease (IBD) with meteorological data based on artificial neural network (ANN). Patients with diagnosis of ulcerative colitis (UC) or Crohn's disease (CD) between 2003 and 2011 were investigated according to the occurrence of onset and flares of symptoms. The expected onset or relapse was calculated on a monthly basis over the study period. For artificial neural network (ANN), patients from 2003 to 2010 were assigned as training cohort and patients in 2011 were assigned as validation cohort. Mean square error (MSE) and mean absolute percentage error (MAPE) were used to evaluate the predictive accuracy. We found no seasonal pattern of onset (P = 0.248) and relapse (P = 0.394) among UC patients. But, the onset (P = 0.015) and relapse (P = 0.004) of CD were associated with seasonal pattern, with a peak in July and August. ANN had average accuracy to predict the frequency of onset (MSE = 0.076, MAPE = 37.58%) and severity of IBD (MSE = 0.065, MAPE = 42.15%) but high accuracy in predicting the frequency of relapse of IBD (MSE = 0.009, MAPE = 17.1%). The frequency of onset and relapse in IBD showed seasonality only in CD, with a peak in July and August, but not in UC. ANN may have its value in predicting the frequency of relapse among patients with IBD.

In alcohol-dependent patients, brain atrophy and functional brain activation elicited by alcohol-associated stimuli may predict relapse. However, to date, the interaction between both factors has not been studied. To determine whether results from structural and functional magnetic resonance imaging are associated with relapse in detoxified alcohol-dependent patients. A cue-reactivity functional magnetic resonance experiment with alcohol-associated and neutral stimuli. After a follow-up period of 3 months, the group of 46 detoxified alcohol-dependent patients was subdivided into 16 abstainers and 30 relapsers. Faculty for Clinical Medicine Mannheim at the University of Heidelberg, Germany. A total of 46 detoxified alcohol-dependent patients and 46 age- and sex-matched healthy control subjects Local gray matter volume, local stimulus-related functional magnetic resonance imaging activation, joint analyses of structural and functional data with Biological Parametric Mapping, and connectivity analyses adopting the psychophysiological interaction approach. Subsequent relapsers showed pronounced atrophy in the bilateral orbitofrontal cortex and in the right medial prefrontal and anterior cingulate cortex, compared with healthy controls and patients who remained abstinent. The local gray matter volume-corrected brain response elicited by alcohol-associated vs neutral stimuli in the left medial prefrontal cortex was enhanced for subsequent relapsers, whereas abstainers displayed an increased neural response in the midbrain (the ventral tegmental area extending into the subthalamic nucleus) and ventral striatum. For alcohol-associated vs neutral stimuli in abstainers compared with relapsers, the analyses of the psychophysiological interaction showed a stronger functional connectivity between the midbrain and the left amygdala and between the midbrain and the left orbitofrontal cortex. Subsequent relapsers displayed increased brain atrophy in brain areas associated with error monitoring and behavioral control. Correcting for gray matter reductions, we found that, in these patients, alcohol-related cues elicited increased activation in brain areas associated with attentional bias toward these cues and that, in patients who remained abstinent, increased activation and connectivity were observed in brain areas associated with processing of salient or aversive stimuli.

Two series of newly diagnosed patients with medulloblastoma are compared in terms of survival, relapse-free survival, and sites of relapse. Patients in series I were all diagnosed and treated prior to 1974 and did not have the benefit of myelography and CSF cytology for staging. All patients treated after 1974 had myelography and most had CSF cytology studies prior to radiotherapy. In addition, patients in the latter series were all followed with CT scanning. Improved survival and relapse-free survival rates were seen in the series II patients. The better results seen in the series II patients are probably due inmore » part to a combination of adequate staging with radiation doses to the neuraxis based on the staging, close followup with CT scanning, and aggressive re-treatment of relapses.« less

Purpose Osteosarcoma (OS) is the most common primary bone tumor. Despite complete surgical removal and intensive chemotherapeutic treatment, 30%-35% of patients with OS have local or systemic recurrence. Some patients survive multiple recurrences, but overall survival after OS recurrence is poor. This analysis aims to describe and identify factors influencing post-relapse survival (PRS) after a second OS relapse. Methods This is a retrospective analysis of 60 patients with a second relapse of OS of the extremities in 2 Italian centers between 2003 and 2013. Results Treatment for first and subsequent relapses was planned according to institutional guidelines. After complete surgical remission (CSR) following the first recurrence, patients experienced a second OS relapse with a median disease-free interval (DFI) of 6 months. Lung disease was prevalent: 44 patients (76%) had pulmonary metastases. Survival after the second relapse was 22% at 5 years. Lung disease only correlated with better survival at 5 years (33.6%) compared with other sites of recurrence (5%; p = 0.008). Patients with a single pulmonary lesion had a better 5-year second PRS (42%; p = 0.02). Patients who achieved a second CSR had a 5-year second PRS of 33.4%. Chemotherapy (p<0.001) benefited patients without a third CSR. Conclusions This analysis confirms the importance of an aggressive, repeated surgical approach. Lung metastases only, the number of lesions, DFI and CSR influenced survival. It also confirms the importance of chemotherapy in patients in whom surgical treatment is not feasible.

Rituximab could be an effective treatment for childhood-onset, complicated, frequently relapsing nephrotic syndrome (FRNS) and steroid-dependent nephrotic syndrome (SDNS). We investigated the efficacy and safety of rituximab in patients with high disease activity. We did a multicentre, double-blind, randomised, placebo-controlled trial at nine centres in Japan. We screened patients aged 2 years or older experiencing a relapse of FRNS or SDNS, which had originally been diagnosed as nephrotic syndrome when aged 1-18 years. Patients with complicated FRNS or SDNS who met all other criteria were eligible for inclusion after remission of the relapse at screening. We used a computer-generated sequence to randomly assign patients (1:1) to receive rituximab (375 mg/m(2)) or placebo once weekly for 4 weeks, with age, institution, treatment history, and the intervals between the previous three relapses as adjustment factors. Patients, guardians, caregivers, physicians, and individuals assessing outcomes were masked to assignments. All patients received standard steroid treatment for the relapse at screening and stopped taking immunosuppressive agents by 169 days after randomisation. Patients were followed up for 1 year. The primary endpoint was the relapse-free period. Safety endpoints were frequency and severity of adverse events. Patients who received their assigned intervention were included in analyses. This trial is registered with the University Hospital Medical Information Network clinical trials registry, number UMIN000001405. Patients were centrally registered between Nov 13, 2008, and May 19, 2010. Of 52 patients who underwent randomisation, 48 received the assigned intervention (24 were given rituximab and 24 placebo). The median relapse-free period was significantly longer in the rituximab group (267 days, 95% CI 223-374) than in the placebo group (101 days, 70-155; hazard ratio: 0·27, 0·14-0·53; p<0·0001). Ten patients (42%) in the rituximab group and six (25%) in the placebo group had at least one serious adverse event (p=0·36). Rituximab is an effective and safe treatment for childhood-onset, complicated FRNS and SDNS. Japanese Ministry of Health, Labour and Welfare. Copyright © 2014 Elsevier Ltd. All rights reserved.

Ibrutinib, a recently approved inhibitor of Bruton's tyrosine kinase (BTK), has shown great efficacy in patients with high-risk CLL. Nevertheless, there are few data regarding its use in patients who relapsed after allogeneic stem cell transplantation (alloSCT). We report clinical data from five CLL patients treated with ibrutinib for relapse after first or even second allogeneic transplantation. Additionally, we performed analyses on cytokine levels and direct measuring of CD4 Th1 and CD4 Th2 cells to evaluate possible clinically relevant immunomodulatory effects of ibrutinib. All patients achieved partial responses including one minimal residual disease (MRD)-negative remission. Within 1 year of follow-up, no relapse was observed. One patient died of severe pneumonia while on ibrutinib treatment. Beside this, no unexpected adverse events were observed. Flow cytometry and analyses of T cell-mediated cytokine levels (IL10 and TNFα) did not reveal substantial changes in T-cell distribution in favor of a CD4 Th1 T-cell shift in our patients. No acute exacerbation of GvHD was reported. In conclusion, these results support further evaluation of ibrutinib in CLL patients relapsing after alloSCT.

Background Alcohol dependence is a chronic relapsing disease. The impairment of response inhibition and alcohol-cue reactivity are the main cognitive mechanisms that trigger relapse. Despite the interaction suggested between the two processes, they have long been investigated as two different lines of research. The present study aimed to investigate the interaction between response inhibition and alcohol-cue reactivity and their potential link with relapse. Materials and methods Event-related potentials were recorded during a variant of a “go/no-go” task. Frequent and rare stimuli (to be inhibited) were superimposed on neutral, nonalcohol-related, and alcohol-related contexts. The task was administered following a 3-week detoxification course. Relapse outcome was measured after 3 months, using self-reported abstinence. There were 27 controls (seven females) and 27 patients (seven females), among whom 13 relapsed during the 3-month follow-up period. The no-go N2, no-go P3, and the “difference” wave (P3d) were examined with the aim of linking neural correlates of response inhibition on alcohol-related contexts to the observed relapse rate. Results Results showed that 1) at the behavioral level, alcohol-dependent patients made significantly more commission errors than controls (P<0.001), independently of context; 2) through the subtraction no-go P3 minus go P3, this inhibition deficit was neurophysiologically indexed in patients with greater P3d amplitudes (P=0.034); and 3) within the patient group, increased P3d amplitude enabled us to differentiate between future relapsers and nonrelapsers (P=0.026). Conclusion Our findings suggest that recently detoxified alcoholics are characterized by poorer response-inhibition skills that demand greater neural resources. We propose that event-related potentials can be used in conjunction with behavioral data to predict relapse; this would identify patients that need a higher level of neural resources when suppressing a response is requested.

Liern, Miguel; Codianni, Paola; Vallejo, Graciela

In the steroid-sensitive nephrotic syndrome (SSNS) the prolonged treatment with steroids could decrease the frequency of relapses. We conducted a comparative study of prolonged steroid scheme and the usual treatment of primary SSNS to assess: the number of patients with relapses, mean time to treatment initiation, to remission and to first relapse, total number of relapses, total cumulative dose of steroids, and the steroid toxicity. Patients were divided into two groups: group A (27 patients) received 16-β-methylprednisolone for 12 weeks, reducing the steroid until week 24. Group B (29 patients) received 16-β-methylprednisolone for 12 weeks and placebo until week 24. Cumulative incidence rate of relapse (person/years) for group A was of 36/100 and 66/100 for group B (p=0.04). Average elapsed time to first relapse was of 114 days for group A and of 75 days to for group B (p=0.01). The difference in time for initial response to treatment and up to achieve remission between both groups was not significant. Total cumulative relapses were 9 for group A and 17 for group B (p=0.04). Total patients with relapses were 3 for group A and 7 for group B (p=0.17). Cumulative average dose per patient was 5,243mg/m 2 for group A and 4,306mg/m 2 for group B (p=0.3), and serum cortisol was 14μg/dl for group A and 16μg/dl for group B (p=0.4). There were no steroid toxicity differences between groups. The duration of the treatment had an impact on the number of relapses without increasing steroid toxicity.

Although discontinuation of suppressive antifungal therapy for acquired immunodeficiency syndrome (AIDS)-associated histoplasmosis is accepted for patients with immunologic recovery, there have been no published studies of this approach in clinical practice, and minimal characterization of individuals who relapse with this disease. We performed a multicenter retrospective cohort study to determine the outcome in AIDS patients following discontinuation of suppressive antifungal therapy for histoplasmosis. Ninety-seven patients were divided into a physician-discontinued suppressive therapy group (PD) (38 patients) and a physician-continued suppressive therapy group (PC) (59 patients). The 2 groups were not statistically different at baseline, but at discontinuation of therapy and at the most recent follow-up there were significant differences in adherence to therapy, human immunodeficiency virus (HIV) RNA, and urinary Histoplasma antigen concentration. There was no relapse or death attributed to histoplasmosis in the PD group compared with 36% relapse (p < 0.0001) and 5% death (p = 0.28) in the PC group. Relapse occurred in 53% of the nonadherent patients but not in the adherent patients (p < 0.0001). Sixty-seven percent of patients with initial central nervous system (CNS) histoplasmosis relapsed compared to 15% of patients without CNS involvement (p = 0.0004), which may be accounted for by nonadherence. In addition, patients with antigenuria above 2.0 ng/mL at 1-year follow-up were 12.82 times (95% confidence interval, 2.91-55.56) more likely to relapse compared to those with antigenuria below 2.0 ng/mL. Discontinuation of antifungal therapy was safe in adherent patients who completed at least 1 year of antifungal treatment, and had CD4 counts >150 cells/mL, HIV RNA <400 c/mL, Histoplasma antigenuria <2 ng/mL (equivalent to <4.0 units in second-generation method), and no CNS histoplasmosis.

Graft-versus-host disease (GvHD)-free, relapse-free survival (GRFS) is a recently reported composite endpoint that allows to simultaneously estimate risk of death, relapse and GvHD after allogeneic hematopoietic stem cell transplantation (HSCT). In this retrospective study comprising 333 patients transplanted for hematologic malignancies, we compared GRFS in patients receiving partial T-cell-depleted (pTCD) grafts with patients receiving T-cell-replete grafts (No-TCD). pTCD was associated with a significantly improved GRFS. The beneficial effect of pTCD on GRFS remained highly significant in multivariable analysis taking into account clinical factors differing between patient groups. We observed no effect of pTCD on overall survival, progression-free survival, and relapse cumulative incidence, while non-relapse mortality cumulative incidence was significantly lower in patients receiving pTCD. The results of our retrospective analysis suggest that pTCD could improve GRFS in allogeneic HSCT recipients without significantly affecting OS and PFS, thus improving patients' quality of life without impairing the curative potential of allogeneic HSCT.

In detoxified alcohol-dependent patients, alcohol-related stimuli can promote relapse. However, to date, the mechanisms by which contextual stimuli promote relapse have not been elucidated in detail. One hypothesis is that such contextual stimuli directly stimulate the motivation to drink via associated brain regions like the ventral striatum and thus promote alcohol seeking, intake and relapse. Pavlovian-to-Instrumental-Transfer (PIT) may be one of those behavioral phenomena contributing to relapse, capturing how Pavlovian conditioned (contextual) cues determine instrumental behavior (e.g. alcohol seeking and intake). We used a PIT paradigm during functional magnetic resonance imaging to examine the effects of classically conditioned Pavlovian stimuli on instrumental choices in n = 31 detoxified patients diagnosed with alcohol dependence and n = 24 healthy controls matched for age and gender. Patients were followed up over a period of 3 months. We observed that (1) there was a significant behavioral PIT effect for all participants, which was significantly more pronounced in alcohol-dependent patients; (2) PIT was significantly associated with blood oxygen level-dependent (BOLD) signals in the nucleus accumbens (NAcc) in subsequent relapsers only; and (3) PIT-related NAcc activation was associated with, and predictive of, critical outcomes (amount of alcohol intake and relapse during a 3 months follow-up period) in alcohol-dependent patients. These observations show for the first time that PIT-related BOLD signals, as a measure of the influence of Pavlovian cues on instrumental behavior, predict alcohol intake and relapse in alcohol dependence. © 2015 Society for the Study of Addiction.

No randomized controlled trials have compared the efficacy of fingolimod or natalizumab as second-line treatment in patients with relapsing-remitting multiple sclerosis (RRMS). To compare clinical outcomes after escalation to fingolimod versus natalizumab in patients with clinically active RRMS. Using the registry of the Swiss Federation for Common Tasks of Health Insurances, we identified patients with RRMS and ≥1 relapse in the year before switching from interferon beta or glatiramer acetate to fingolimod or natalizumab. Propensity score matching was used to select patients with comparable baseline characteristics. Relapse and Expanded Disability Status Scale (EDSS) outcomes were compared in paired, pairwise-censored analyses. Of the 547 included patients, 358 were matched (fingolimod, n = 179; natalizumab, n = 179). Median follow-up time was 1.8 years (interquartile range 0.9-2.9). Patients switching to natalizumab had a lower risk of relapses (incidence rate ratio 0.5, 95% confidence interval (CI) 0.3-0.8, p = 0.001) and were more likely to experience EDSS improvement (hazard ratio (HR) 1.8, 95% CI 1.1-2.7, p = 0.01) compared to fingolimod. We found no differences in the proportion of patients free from EDSS progression (HR 0.9, 95% CI 0.5-1.5, p = 0.62). Natalizumab seems to be more effective in reducing relapse rate and improving disability compared with fingolimod.

California, United States. To determine the frequency of tuberculosis (TB) patients at risk for relapse who received at least 9 months of anti-tuberculosis treatment (extended treatment) and to identify factors associated with not receiving extended treatment. We analyzed characteristics of culture-confirmed pulmonary TB patients reported to the California TB Registry during 2004-2009. Patients with cavities on initial chest radiograph and delayed culture conversion (⩾70 days) were at 'high risk of relapse', and anti-tuberculosis treatment of ⩾270 days was 'extended treatment'. We used a generalized linear model to identify independent risk factors for absence of extended treatment in the high risk of relapse group. Among 5680 TB patients, 483 (8.5%) were at high risk of relapse: 372 (77%) received extended treatment but 111 (23%) did not. Factors associated with absence of extended treatment included negative sputum smears (adjusted prevalence ratio [aPR] 2.62, 95%CI 1.69-4.05), residence in three specific counties (aPR 1.71, 95%CI 1.19-2.46) and Black race (aPR 1.56, 95%CI 1.03-2.38). Nearly a quarter of TB patients at high risk of relapse did not receive extended treatment. Increased efforts are needed to ensure that all patients who may benefit from extended anti-tuberculosis treatment receive it.

Relieving catatonia helps identify the underlying etiology and its treatment. However, catatonia may reemerge after some time, but there are few data on the relapses and recurrences of catatonia. We aimed to investigate the characteristics of patients with relapses or recurrences of catatonia as well as the efficacy of the lorazepam-diazepam protocol on them. Patients with catatonia who had more than one episode of catatonia and were treated with the lorazepam-diazepam protocol were identified. Their medical charts were reviewed, and interview was conducted. Thirty patients were identified. Nineteen (63.3%) were diagnosed with schizophrenia, five (16.7%) with major depressive disorder, two (6.7%) with bipolar disorder, and four (13.3%) with general medical conditions. In the 68 relapses and relapses the lorazepam-diazepam protocol was used, full response was reported in 54 (79.4%) of them. Twelve of 19 (63.2%) patients with schizophrenia were treated with clozapine. Twenty (66.7%) out of 30 patients were maintained on oral lorazepam by the time of discharge. Literature review showed similar prevalence of schizophrenia in patients with more than one episode of catatonia, and a wide variety of treatment options. The lorazepam-diazepam protocol was mostly effective in managing relapses and recurrences of catatonia. Maintenance clozapine and oral lorazepam were beneficial in a significant number of patients.

Allogeneic stem-cell transplant (allo-SCT) is the standard of care for pediatric patients with acute lymphoblastic leukemia (ALL) who relapse after frontline chemotherapy; however, for patients who relapse after allo-SCT, outcomes are very poor. Few studies have examined overall survival in this patient population, particularly in patients who received a second allo-SCT. This was a retrospective analysis using data from the Center for International Blood and Marrow Transplant Research (CIBMTR) registry. The study population included patients aged 3 to 21 years who were diagnosed with B-ALL and underwent their first allo-SCT between 2009 and 2013. The primary endpoint was the time from the date of posttransplant relapse to the date of death due to any reason. Outcomes in 1349 pediatric and young-adult patients were included in this analysis. The Kaplan-Meier estimated probability of survival at 3 years after first allo-SCT was 63.1% (95% CI, 60.2%-65.8%). Overall, 29.2% of patients relapsed after first allo-SCT and had a median survival of 7.4 months (95% CI, 6.0-9.6 months). Twenty-five patients in the analysis developed secondary malignancies, most of which were lymphoproliferative disorders. Survival rates are low in pediatric and young-adult patients who relapse after first and second allo-SCT, and new therapies are needed to improve outcomes in this population. This data can be used as a historical comparison for single-arm trials of novel therapies for this patient population, including chimeric antigen receptor T-cell therapy.

Background/Aims In Taiwan, due to budget limitations, the National Health Insurance only allows for a limited period of biologics use in treating moderate to severe Crohn's disease (CD). We aimed to access the outcomes of CD patients following a limited period use of biologics, specifically focusing on the relapse rate and remission duration; also the response rate to second use when applicable. Methods This was a multicenter, retrospective, observational study and we enrolled CD patients who had been treated with adalimumab (ADA) according to the insurance guidelines from 2009 to 2015. Results A total of 54 CD patients, with follow-up of more than 6 months after the withdrawal of ADA, were enrolled. The average period of treatment with ADA was 16.7±9.7 months. After discontinuing ADA, 59.3% patients suffered a clinical relapse. In the univariate analysis, the reason for withdrawal was a risk factor for relapse (P=0.042). In the multivariate analysis, current smoker became an important risk factor for relapse (OR, 3.9; 95% CI, 1.2−14.8; P=0.044) and male sex was another risk factor (OR, 2.9; 95% CI, 1.1−8.6; P=0.049). For those 48 patients who received a second round of biologics, the clinical response was seen in 60.4%, and 1 anaphylaxis occurred. Conclusions Fifty-nine percent of patients experienced a relapse after discontinuing the limited period of ADA treatment, and most of them occurred within 1 year following cessation. Male sex and current smoker were risk factors for relapse. Though 60.4% of the relapse patients responded to ADA again. PMID:29142516

Methotrexate (MTX) alternating with folinic acid is a commonly used treatment regimen for low-risk gestational trophoblastic neoplasia (GTN). In The Netherlands, two courses of MTX are administered after normalization of serum human chorionic gonadotrophin (hCG) levels (consolidation courses), whereas in the United Kingdom, three consolidation courses are given. In a retrospective setting we compared relapse rates of women completing MTX therapy for low-risk GTN in The Netherlands and the UK. From 1980 to 2008, 351 patients were collected from the Dutch Central Registry for Hydatidiform Moles and records from the Dutch Working Party on Trophoblastic Disease. From the Charing Cross Hospital Trophoblast Disease Centre (London), 600 low-risk GTN patients were identified from 1992 to 2008. In 4.0% of patients relapse occurred after MTX treatment with three consolidation courses, whereas 8.3% of patients relapsed after MTX treatment with two consolidation courses (p=0.006). Although patients from The Netherlands had a higher level of hCG (p<0.001) and more patients had metastases before the start of treatment (p=0.012), the number of courses of MTX to achieve a normal hCG did not differ significantly between patients from The Netherlands and the UK (p=0.375). Relapse rates were higher in patients treated with two consolidation courses of MTX. Although other factors might have influenced the observed difference in relapse rates, three courses of consolidation chemotherapy may be preferable to two in the treatment of low-risk GTN in order to decrease the risk of disease relapse. A prospective randomized study would be required to confirm these findings. Copyright © 2012 Elsevier Inc. All rights reserved.

Acute lymphoblastic leukemia (ALL) is the most common childhood cancer worldwide. Mexican patients have high mortality rates, low frequency of good prognosis biomarkers (i.e., ETV6-RUNX1) and a high proportion is classified at the time of diagnosis with a high risk to relapse according to clinical features. In addition, very early relapses are more frequently observed than in other populations. The aim of the study was to identify new potential biomarkers associated with very early relapse in Mexican ALL children through transcriptome analysis. Microarray gene expression profiling on bone marrow samples of 54 pediatric ALL patients, collected at time of diagnosis and/or at relapse, was performed. Eleven patients presented relapse within the first 18 months after diagnosis. Affymetrix Human Transcriptome Array 2.0 (HTA 2.0) was used to perform gene expression analysis. Annotation and functional enrichment analyses were carried out using Gene Ontology, KEGG pathway analysis and Ingenuity Pathway Analysis tools. BLVRB, ZCCHC7, PAX5, EBF1, TMOD1 and BLNK were differentially expressed (fold-change >2.0 and p value <0.01) between relapsed and non-relapsed patients. Functional analysis of abnormally expressed genes revealed their important role in cellular processes related to the development of hematological diseases, cancer, cell death and survival and in cell-to-cell signaling interaction. Our data support previous findings showing the relevance of PAX5, EBF1 and ZCCHC7 as potential biomarkers to identify a subgroup of ALL children in high risk to relapse. Copyright © 2016 IMSS.

Alcohol relapse after liver transplant heightens concern about recurrent disease, nonadherence to the immunosuppression regimen, and death. To develop a scoring system to stratify risk of alcohol relapse after liver transplant. Retrospective medical record review. All adult liver transplants performed from May 2002 to February 2011 at a single center in the United States. The incidence of return to any alcohol consumption after liver transplant. Thirty-four percent (40/118) of patients with a history of alcohol abuse/dependency relapsed to use of any alcohol after liver transplant. Nine of 25 hypothesized risk factors were predictive of alcohol relapse after liver transplant: absence of hepatocellular carcinoma, tobacco dependence, continued alcohol use after liver disease diagnosis, low motivation for alcohol treatment, poor stress management skills, no rehabilitation relationship, limited social support, lack of nonmedical behavioral consequences, and continued engagement in social activities with alcohol present. Each independent predictor was assigned an Alcohol Relapse Risk Assessment (ARRA) risk value of 1 point, and patients were classified into 1 of 4 groups by ARRA score: ARRA I = 0, ARRA II = 1 to 3, ARRA III = 4 to 6, and ARRA IV = 7 to 9. Patients in the 2 higher ARRA classifications had significantly higher rates of alcohol relapse and were more likely to return to pretransplant levels of drinking. Alcohol relapse rates are moderately high after liver transplant. The ARRA is a valid and practical tool for identifying pretransplant patients with alcohol abuse or dependency at elevated risk of any alcohol use after liver transplant.

Seasonal variation of relapses in multiple sclerosis (MS) suggests that season-dependent factors, such as ambient air pollution, may trigger them. However, only few studies have considered possible role of air pollutants as relapse's risk factor. We investigated the effect of particulate matter of aerodynamic diameter smaller than 10µm (PM 10 ) on MS relapses. In total, 536 relapsing MS patients from Strasbourg city (France) were included, accounting for 2052 relapses over 2000-2009 period. A case-crossover design was used with cases defined as the days of relapse and controls being selected in the same patient at plus and minus 35 days. Different lags from 0 to 30 days were considered. Conditional logistic regressions, adjusted on meteorological parameters, school and public holidays, were used and exposure was considered first as a quantitative variable and second, as a binary variable. The natural logarithm of the average PM 10 concentration lagged from 1 to 3 days before relapse onset was significantly associated with relapse risk (OR =1.40 [95% confidence interval 1.08-1.81]) in cold season. Consistent results were observed when considering PM 10 as a binary variable, even if not significant. With an appropriate study design and robust ascertainment of neurological events and exposure, the present study highlights the effect of PM 10 on the risk of relapse in MS patients, probably through oxidative stress mechanisms.

Introduction: Relapse is the most common smoking cessation outcome. Accurate prediction of relapse likelihood could be an important clinical tool used to influence treatment selection or duration. The aim of this research was to develop a brief clinical relapse proneness questionnaire to be used with smokers interested in quitting in a clinical setting where time is at a premium. Methods: Diverse items assessing constructs shown in previous research to be related to relapse risk, such as nicotine dependence and self-efficacy, were evaluated to determine their independent contributions to relapse prediction. In an exploratory dataset, candidate items were assessed among smokers motivated to quit smoking who enrolled in one of three randomized controlled smoking cessation trials. A cross-validation dataset was used to compare the relative predictive power of the new instrument against the Fagerström Test for Nicotine Dependence (FTND) at 1-week, 8-week, and 6-month postquit assessments. Results: We selected seven items with relatively nonoverlapping content for the Wisconsin Predicting Patient's Relapse (WI-PREPARE) measure, a brief, seven-item questionnaire that taps physical dependence, environmental factors, and individual difference characteristics. Cross-validation analyses suggested that the WI-PREPARE demonstrated a stronger prediction of relapse at 1-week and 8-week postquit assessments than the FTND and comparable prediction to the FTND at a 6-month postquit assessment. Discussion: The WI-PREPARE is easy to score, suggests the nature of a patient's relapse risk, and predicts short- and medium-term relapse better than the FTND. PMID:19372573

Safety, tolerability and efficacy profiles of interferon beta (IFNbeta) therapy in relapsing multiple sclerosis (MS) has been widely verified both in trial settings and in daily clinical practice. However, for a variable percentage of treated patients, it remains only partially effective. In this study, we reported the post-marketing experience of the efficacy of IFNbeta therapy for a large cohort of MS patients regularly attending the MS Outpatient Clinic of "La Sapienza University" in Rome. In this cohort we also sought clinical and paraclinical variables responsible for the clinical course of MS during IFNbeta therapy. Patients that received treatment with one of the IFNbeta formulations for at least 1 year were included. Clinical outcomes (i. e., relapses and disability score) were monitored throughout the entire study period. Magnetic resonance imaging (MRI) scans were performed twice for each subject: at baseline and after 1 year of therapy. The occurrence of more than one relapse during the study period or a sustained disability progression in the Expanded Disability Status Scale (EDSS) score were considered as criteria for the definition of suboptimal clinical response to IFNbeta therapy. During IFNbeta therapy (number of patients 242, mean length of treatment 4.3+/-2.3 years) a reduction in the annualised relapse rate of 59% (p<0.001) was observed. Eighty-six patients (35%) fulfilled the criterion for defining "suboptimal responder" on the basis of relapses, and 69 (28.5%) did the same on the basis of EDSS sustained progression. Twenty-seven (11.1%) patients showed both an EDSS progression and two or more relapses. The presence of T1-enhancing lesions and new T2 hyperintense lesions on the scan performed after the first year of therapy were the best MRI features associated with both the occurrence of relapses during the treatment period (OR for enhancing lesions and relapses 3.6; OR for new T2 lesion and relapses 2.8). The present post-marketing experience confirms the efficacy of IFNbeta in modifying the natural course of MS and encourages the use of paraclinical variables measuring subclinical disease activity as surrogate markers to monitor the clinical course of MS during IFNbeta therapy.

Nodular lymphocyte-predominant Hodgkin lymphoma (NLPHL) is a rare lymphoma (< 5% of Hodgkin's lymphomas) predominantly affecting the middle-aged man, with an indolent behavior. Given the rare occurrence of this lymphoma, there are currently no clear guidelines for initial treatment or relapse. In this report, we present the follow up of two patients treated by radioimmunotherapy for first relapse of their NLPHL. Both patients were initially treated with rituximab and relapsed 1 year after the end of their treatment. This article is protected by copyright. All rights reserved.

Relapse is a threat in patients treated for acute lymphoblastic leukemia (ALL). Methylenetetrahydrofolate reductase (MTHFR) activity may affect the sensitivity of patients to folate-based chemotherapeutic drugs, thus influencing the relapse risk. Two polymorphisms of the gene encoding MTHFR, C677T and A1298C, alter MTHFR enzyme activity and may be associated with ALL relapse. The aim of this meta-analysis was to clarify the correlation between the C677T and A1298C polymorphisms and ALL relapse. To this end, data were collected from studies of the association between these two polymorphisms and ALL relapse. Analysis of the data revealed a serious contradiction among the results. A recessive model demonstrated that the ALL relapse risk was significantly increased in carriers of the 677 TT genotype, especially for pediatric ALL, but was unaffected by the A1298C polymorphism. These findings confirm that the MTHFR C677T polymorphism could be considered as a good marker of the pediatric ALL relapse risk.

Surgery of hypospadias represents an interesting field of innovatory ideas. Many methods may be suitable and many modifications can be performed. There is no one method for all kinds of hypospadias. It is necessary to find the right method for each patient. The result often depends upon the experience of the surgeon with a particular method. The choice between straightening and urethroplasty in one or two stages depends on cost-benefit ratio and evolution at distance of the straightening must be taken into account as well tissue consumption imposed by the urethroplasty, with one stage straightening that makes reintervention very difficult. In the latter case, a multi-stage operation will be necessary with flaps for urethroplasty after the straightening, or, in a more developed penis, a shortening operation according to Nesbit. With two-stage method, in case of relapsed curvature, this can easily be treated, if tissue is available. For a good result of urethroplasty the ability of surgeon, a constant calibration of the canal, plenty of elastic tissue for the neo-urethra, care not to suture on these planes, are highly important. In our opinion Duplay's method observes these requisites. Two-stages surgery allows easy correction of any eventual relapsing incurvature, with no problems for the following urethroplasty. One-stage surgery allows the problems to be resolved in a single surgical Step, but involves the risk of tissue consumption and proximal stricture.

Duration of initial disease response remains a strong prognostic factor in multiple myeloma (MM) particularly for upfront autologous hematopoietic cell transplant (AHCT) recipients. We hypothesized that new drug classes and combinations employed prior to AHCT as well as after post-AHCT relapse may have changed the natural history of MM in this population. We analyzed the Center for International Blood and Marrow Transplant Research database to track overall survival (OS) of MM patients receiving single AHCT within 12 months after diagnosis (N=3256) and relapsing early post-AHCT (<24 months), and to identify factors predicting for early vs late relapses (24-48 months post-AHCT). Over three periods (2001-2004, 2005-2008, 2009-2013), patient characteristics were balanced except for lower proportion of Stage III, higher likelihood of one induction therapy with novel triplets and higher rates of planned post-AHCT maintenance over time. The proportion of patients relapsing early was stable over time at 35-38%. Factors reducing risk of early relapse included lower stage, chemosensitivity, transplant after 2008 and post-AHCT maintenance. Shorter post-relapse OS was associated with early relapse, IgA MM, Karnofsky <90, stage III, >1 line of induction and lack of maintenance. Post-AHCT early relapse remains a poor prognostic factor, even though outcomes have improved over time.

Primary cutaneous marginal zone B-cell lymphomas are low-grade lymphomas running an indolent course. Skin relapses have been frequently reported but little information about disease-free survival (DFS) is available. We sought to evaluate relapse rate and DFS in patients with primary cutaneous marginal zone B-cell lymphomas. Clinical features, European Organization for Research and Treatment of Cancer/International Society for Cutaneous Lymphomas stage, light chain restriction, clonality, treatments, skin relapses, DFS, stage progression, extracutaneous disease, and outcome are analyzed in a series of 137 patients. Patients were classified as solitary lesion (T1) (n = 70; 51%), regional skin involvement (T2) (n = 40; 29%), and generalized skin lesions (T3) (n = 27; 20%). Surgical excision, local radiotherapy, or a combination were the initial treatment in 118 patients (86%). In 121 of 137 patients (88%) a complete remission was observed after initial treatment, including 99 of 106 patients (93%) with solitary or localized disease and 22 of 31 patients (71%) with multifocal lesions. Cutaneous relapses were observed in 53 patients (44%). Median DFS was 47 months. Patients with multifocal lesions or T3 disease showed higher relapse rate and shorter DFS. No significant differences were observed between surgery and radiotherapy, but surgery alone was associated with more recurrences at initial site. Overall survival at 5 and 10 years was 93%. Six patients (4%) developed extracutaneous disease during follow-up. This was a case series retrospective study. Our results support long-term follow-up in patients with primary cutaneous marginal zone B-cell lymphomas. Disseminated skin lesions have higher relapse rate and shorter DFS suggesting further investigation on systemic therapies in such a group of patients.

Limited therapeutic options are available after relapse of acute leukaemia following first reduced intensity conditioning haematopoietic stem cell transplantation (RIC1). A retrospective study on European Society for Blood and Marrow Transplantation (EBMT) registry data was performed on 234 adult patients with acute leukaemia who received a second RIC transplantation (RIC2) from 2000 to 2012 as a salvage treatment for relapse following RIC1. At the time of RIC2, 167 patients (71.4%) had relapsed or refractory disease, 49 (20.9%) were in second CR and 18 (7.7%) in third or higher CR. With a median follow-up of 21 (1.5-79) months after RIC2, 51 patients are still alive. At 2 years, the cumulative incidence of non-relapse mortality (NRM), relapse incidence (RI), leukaemia-free survival (LFS) and overall survival (OS) were 22.4% (95% confidence interval (CI): 17-28.4), 63.9% (56.7-70.1), 14.6% (8.8-18.5) and 20.5% (14.9-26.1), respectively. In patients with acute myelogenous, biphenotypic and undifferentiated leukaemia (representing 89.8% of all patients), duration of remission following RIC1 >225 days, presence of CR at RIC2, patient's Karnofsky performance status >80 at RIC2 and non-myeloablative conditioning were found to be the strongest predictors of patients' favourable outcome.

Allogeneic hematopoietic stem-cell transplantation (ahsct) is associated with significant morbidity and mortality, but it can cure carefully selected patients with acute myeloid leukemia (aml) in second remission (cr2). In a cohort of patients with aml who underwent ahsct in cr2, we determined the pre-transplant factors that predicted for overall survival (os), relapse, and non-relapse mortality. We also sought to validate the prognostic risk groups derived by Michelis and colleagues in this independent population. In a retrospective chart review, we obtained data for 55 consecutive patients who underwent ahsct for aml in cr2. Hazard ratios were used to describe the independent effects of pre-transplant variables on outcome, and Kaplan-Meier curves were used to assess outcomes in the three prognostic groups identified by Michelis and colleagues. At 1, 3, and 5 years post-transplant, os was 60%, 45.5%, and 37.5% respectively. Statistically significant differences in os, relapse mortality, and non-relapse mortality were not identified between the prognostic risk groups identified by Michelis and colleagues. Women were less likely than men to relapse, and a modified European Society for Blood and Marrow Transplantation (mebmt) score of 3 or less was associated with a lower non-relapse mortality. The 37.5% 5-year os in this cohort suggests that, compared with other options, ahsct offers patients with aml in cr2 a better chance of cure. Our study supports the use of the mebmt score to predict non-relapse mortality in this population.

There are no studies on the factors associated with gastroesophageal reflux disease (GERD) relapse in primary care patients. To identify the risk factors associated with GERD relapse in primary care patients that responded adequately to short-term treatment with a proton pump inhibitor. A cohort study was conducted that included GERD incident cases. The patients received treatment with omeprazole for 4 weeks. The ReQuest questionnaire and a risk factor questionnaire were applied. The therapeutic success rate and relapse rate were determined at 4 and 12 weeks after treatment suspension. A logistic regression analysis of the possible risk factors for GERD relapse was carried out. Of the 83 patient total, 74 (89.16%) responded to treatment. Symptoms recurred in 36 patients (48.64%) at 4 weeks and in 13 patients (17.57%) at 12 weeks, with an overall relapse rate of 66.21%. The OR multivariate analysis (95% CI) showed the increases in the possibility of GERD relapse for the following factors at 12 weeks after treatment suspension: basic educational level or lower, 24.95 (1.92-323.79); overweight, 1.76 (0.22-13.64); obesity, 0.25 (0.01-3.46); smoking, 0.51 (0.06-3.88); and the consumption of 4-12 cups of coffee per month, 1.00 (0.12-7.84); citrus fruits, 14.76 (1.90-114.57); NSAIDs, 27.77 (1.12-686.11); chocolate, 0.86 (0.18-4.06); ASA 1.63 (0.12-21.63); carbonated beverages, 4.24 (0.32-55.05); spicy food 7-16 times/month, 1.39 (0.17-11.17); and spicy food ≥ 20 times/month, 4.06 (0.47-34.59). The relapse rate after short-term treatment with omeprazole was high. The consumption of citrus fruits and NSAIDs increased the possibility of GERD relapse.

Episode remission in unipolar major depression, while distinguished by minimal symptom burden, can also be a period of marked sensitivity to emotional stress as well as an increased risk of relapse. To examine whether mood-linked changes in dysfunctional thinking predict relapse in recovered patients who were depressed. In phase 1 of this study, patients with major depressive disorder were randomly assigned to receive either antidepressant medication or cognitive behavior therapy. In phase 2, patients who achieved clinical remission underwent sad mood provocation and were then observed with regular clinical assessments for 18 months. Outpatient psychiatric clinics at the Centre for Addiction and Mental Health, Toronto, Ontario. A total of 301 outpatients with major depressive disorder, aged 18 to 65 years, participated in phase 1 of this study and 99 outpatients with major depressive disorder in remission, aged 18 to 65 years, participated in phase 2. Occurrence of a relapse meeting DSM-IV criteria for a major depressive episode as assessed by the longitudinal interval follow-up evaluation and a Hamilton Depression Rating Scale score of 16 or greater. Patients who recovered through antidepressant medication showed greater cognitive reactivity following the mood provocation than those who received cognitive behavior therapy. Regardless of type of prior treatment, the magnitude of mood-linked cognitive reactivity was a significant predictor of relapse over the subsequent 18 months. Patients whose mood-linked endorsement of dysfunctional attitudes increased by a minimum of 8 points had a significantly shorter time to relapse than those whose scores were not as elevated. The vulnerability of remitted depressed patients for illness relapse may be related to the (re)activation of depressive thinking styles triggered by temporary dysphoric states. This is the first study to link such differences to prognosis following successful treatment for depression. Further understanding of factors predisposing to relapse/recurrence in recovered patients may help to shorten the potentially lifelong course of depression.

Multiple sclerosis (MS) is a central nervous system autoimmune inflammatory T-cell-mediated disease with a relapsing-remitting course in the majority of patients. In this study, we performed a high-resolution systems biology analysis of gene expression and physical interactions in MS relapse and remission. To this end, we integrated 164 large-scale measurements of gene expression in peripheral blood mononuclear cells of MS patients in relapse or remission and healthy subjects, with large-scale information about the physical interactions between these genes obtained from public databases. These data were analyzed with a variety of computational methods. We find that there is a clear and significant global network-level signal that is related to the changes in gene expression of MS patients in comparison to healthy subjects. However, despite the clear differences in the clinical symptoms of MS patients in relapse versus remission, the network level signal is weaker when comparing patients in these two stages of the disease. This result suggests that most of the genes have relatively similar expression levels in the two stages of the disease. In accordance with previous studies, we found that the pathways related to regulation of cell death, chemotaxis and inflammatory response are differentially expressed in the disease in comparison to healthy subjects, while pathways related to cell adhesion, cell migration and cell-cell signaling are activated in relapse in comparison to remission. However, the current study includes a detailed report of the exact set of genes involved in these pathways and the interactions between them. For example, we found that the genes TP53 and IL1 are 'network-hub' that interacts with many of the differentially expressed genes in MS patients versus healthy subjects, and the epidermal growth factor receptor is a 'network-hub' in the case of MS patients with relapse versus remission. The statistical approaches employed in this study enabled us to report new sets of genes that according to their gene expression and physical interactions are predicted to be differentially expressed in MS versus healthy subjects, and in MS patients in relapse versus remission. Some of these genes may be useful biomarkers for diagnosing MS and predicting relapses in MS patients.

Low 25-hydroxy vitamin D (25-[OH]-D) serum concentrations have been associated with higher disease activity in multiple sclerosis (MS) patients. In a large cross-sectional study we assessed the vitamin D status in MS patients in relation to seasonality and relapse rate. 415 MS-patients (355 relapsing-remitting MS and 60 secondary-progressive, 282 female, mean age 39.1years) of whom 25-(OH)-D serum concentrations were determined at visits between 2010 and 2013 were included in the study. All clinical data including relapse at visit and expanded disability status scale were recorded in a standardized manner by an experienced neurologist. Seasonal variations of 25-(OH)-D serum concentrations were modelled by sinusoidal regression and seasonal variability in the prevalence of relapse by cubic regression. The mean 25-(OH)-D serum concentration was 24.8ng/ml (range 8.3-140ng/ml) with peak levels of 32.2ng/ml in July/August and nadir in January/February (17.2ng/ml). The lowest modelled prevalence of relapse was in September/October (28%) and the highest modelled prevalence in March/April (47%). The nadir of 25-(OH)-D serum concentrations preceded the peak in prevalence of relapses by two months. In summary, seasonal variation of 25-(OH)-D serum levels were inversely associated with clinical disease activity in MS patients. Future studies should investigate whether vitamin D supplementation in MS patients may decrease the seasonal risk for MS relapses. Copyright © 2017 Elsevier B.V. All rights reserved.

Peripheral T-cell lymphoma carries a poor prognosis. To document a possible graft-versus-lymphoma effect in this setting, we evaluated the impact of immunomodulation in 63 patients with peripheral T-cell lymphoma who relapsed after allogeneic transplant in 27 SFGM-TC centers. Relapse occurred after a median of 2.8 months. Patients were then treated with non-immunologic strategies (chemotherapy, radiotherapy) and/or immune modulation (donor lymphocyte infusions (DLI) and/or discontinuation of immunosuppressive therapy). Median overall survival (OS) after relapse was 6.1 months (DLI group: 23.6 months, non-DLI group: 3.6 months). Among the 14 patients who received DLI, 9 responded and 2 had stable disease. Among the remaining 49 patients, a complete response accompanied by extensive chronic GvHD was achieved in two patients after tapering of immunosuppressive drugs. Thirty patients received radio-chemotherapy, with an overall response rate of 50%. In multivariate analysis, chronic GvHD (odds ratio: 11.25 (2.68-48.21), P=0.0009) and skin relapse (odds ratio: 4.15 (1.04-16.50), P=0.043) were associated with a better response to treatment at relapse. In a time-dependent analysis, the only factor predictive of OS was the time from transplantation to relapse (hazards ratio: 0.33 (0.17-0.640), P=0.0009). This large series provides encouraging evidence of a true GvL effect in this disease.

The Relapse Assessment for Schizophrenia Patients (RASP) was developed as a six-question self-report screener that measures indicators of Increased Anxiety and Social Isolation to assess patient stability and predict imminent relapse. This paper describes the development and psychometric characteristics of the RASP. The RASP and Positive and Negative Syndrome Scale (PANSS) were administered to patients with schizophrenia (n=166) three separate times. Chart data were collected on a subsample of patients (n=81). Psychometric analyses of RASP included tests of reliability, construct validity, and concurrent validity of items. Factors from RASP were correlated with subscales from PANSS (sensitivity to change and criterion validity [agreement between RASP and evidence of relapse]). Test-retest reliability returned modest to strong agreement at the item level and strong agreement at the questionnaire level. RASP showed good item response curves and internal consistency for the total instrument and within each of the two subscales (Increased Anxiety and Social Isolation). RASP Total Score and subscales showed good concurrent validity when correlated with PANSS Total Score, Positive, Excitement, and Anxiety subscales. RASP correctly predicted relapse in 67% of cases, with good specificity and negative predictive power and acceptable positive predictive power and sensitivity. The reliability and validity data presented support the use of RASP in settings where addition of a brief self-report assessment of relapse risk among patients with schizophrenia may be of benefit. Ease of use and scoring, and the ability to administer without clinical supervision allows for routine administration and assessment of relapse risk.

HSCT provides the opportunity to replace a damaged tissue. It is the most important treatment for high risk hematologic malignant and non malignant disorders. An important challenge in the identification of matched donors/patients is the HLA diversity. The Mexican Bone Marrow Registry (DONORMO) has nowadays > 5000 donors. The prevalent alleles are Amerindian, Mediterranean (Semitic and Spanish genes) and African. In theory, it is possible to find 11% of 6/6 A-B-DR low resolution matches for 70% of patients with Mexican ancestry. We contributed with 39 unrelated, cord blood and autologous HSCT for patients with malignant, genetic and autoimmune disorders. Overall disease survival was 50% (2-7 years) depending on the initial diagnosis, conditioning, disease evolution or other factors. Clinical studies using autologous and unrelated HSC are performed on patients with refractory autoimmune diseases producing mixed results: mainly, T1D, RA, MS, SLE. Improvement has been observed in skin damage and quality of life in SLE and systemic sclerosis. Disease stabilization in 2/3 of MS patients. However, in RA and T1D, initial benefits have been followed by eventual relapse. With growing clinical experience and protocol improvement, treatment-related mortality is decreasing. Proof efficacy will be achieved by comparing HSCT with standard therapy in autoimmunity.

Neoadjuvant or adjuvant therapy for resectable esophageal cancer: is there a standard of care?

Carcinoma of the esophagus is an aggressive and lethal disease with an increasing incidence worldwide. Despite changes in the treatment approach over the past two decades and even following complete resection, most patients will eventually relapse and die as a result of their disease. Several clinical trials evaluated different modalities in treating locally advanced esophageal cancer; however, because of stage migration and the changes in disease epidemiology, applying these trials to clinical practice has become a daunting task. We searched Medline and conference abstracts for randomized studies published in the past three decades. We restricted our search to articles published in English. Neoadjuvant chemoradiotherapy followed by surgical resection is an accepted standard of care in the United States for patients with locally advanced esophageal cancer. Esophagectomy remains an essential component of treatment and can lead to improved overall survival, especially when performed at high-volume institutions. The role of adjuvant chemotherapy following curative resection in patients who underwent neoadjuvant chemotherapy and radiation remains unclear. Several questions still need to be answered regarding the use of neoadjuvant or adjuvant therapy for patients with resectable esophageal cancer. The optimal chemotherapy regimen has not yet been identified for these patients, although newer therapies show promise.

Addiction is supposedly characterized by a shift from goal-directed to habitual decision making, thus facilitating automatic drug intake. The two-step task allows distinguishing between these mechanisms by computationally modeling goal-directed and habitual behavior as model-based and model-free control. In addicted patients, decision making may also strongly depend upon drug-associated expectations. Therefore, we investigated model-based versus model-free decision making and its neural correlates as well as alcohol expectancies in alcohol-dependent patients and healthy controls and assessed treatment outcome in patients. Ninety detoxified, medication-free, alcohol-dependent patients and 96 age- and gender-matched control subjects underwent functional magnetic resonance imaging during the two-step task. Alcohol expectancies were measured with the Alcohol Expectancy Questionnaire. Over a follow-up period of 48 weeks, 37 patients remained abstinent and 53 patients relapsed as indicated by the Alcohol Timeline Followback method. Patients who relapsed displayed reduced medial prefrontal cortex activation during model-based decision making. Furthermore, high alcohol expectancies were associated with low model-based control in relapsers, while the opposite was observed in abstainers and healthy control subjects. However, reduced model-based control per se was not associated with subsequent relapse. These findings suggest that poor treatment outcome in alcohol dependence does not simply result from a shift from model-based to model-free control but is instead dependent on the interaction between high drug expectancies and low model-based decision making. Reduced model-based medial prefrontal cortex signatures in those who relapse point to a neural correlate of relapse risk. These observations suggest that therapeutic interventions should target subjective alcohol expectancies. Copyright © 2017 Society of Biological Psychiatry. Published by Elsevier Inc.

Clinical predictors for myasthenia gravis relapse and ocular myasthenia gravis secondary generalization during the first two years after disease onset remain incompletely identified. This study attempts to investigate the clinical predictors for the prognosis of Myasthenia Gravis. Eighty three patients with myasthenia gravis were concluded in this study. Baseline characteristics were analyzed as predictors. Relapse of myasthenia gravis developed in 26 patients (34%). Generalization developed in 34 ocular myasthenia gravis patients (85%). Other autoimmune diseases were observed more commonly in relapsed myasthenia gravis (P = 0.012). Second generalization group contained more late onset patients (P = 0.021). Ocular myasthenia gravis patients with thymus hyperplasia progressed more rapidly than those with other thymus pathology (P = 0.027). Single onset symptom of ocular myasthenia gravis such as ptosis or diplopia predicted early progression than concurrence of ptosis and diplopia (P = 0.027). Treatment effect including glucocorticoid, pyridostigmine, thymectomy, IVIG, immunosuppressive drugs did not show significant difference between the relapsed and non-relapsed groups. The treatment outcome also showed no difference between the single OMG and second generalized groups. Occurrence of associated autoimmune disease can serve as a potential predictor for myasthenia gravis relapse. Either ptosis or diplopia, as well as thymic hyperplasia can predict generalization in the first six months.

Central nervous system (CNS) relapse in non-Hodgkin lymphoma (NHL) carries a very poor prognosis. Risk factors and outcome have been studied in aggressive B-cell lymphomas, but very little is known about the risk in peripheral T-cell lymphoma (PTCL). We aimed at analyzing risk factors for CNS involvement at first relapse or progression, as well as the outcome of these patients, in a large population-based cohort of patients with PTCL. Twenty-eight out of 625 patients (4.5%) developed CNS disease over time. In multivariable analysis, disease characteristics at diagnosis independently associated with an increased risk for later CNS involvement were involvement of more than 1 extranodal site (hazard ratio [HR], 2.60; 95% confidence interval [CI], 1.07-6.29; P = .035) and skin (HR, 3.51; 95% CI, 1.26-9.74; P = .016) and gastrointestinal involvement (HR, 3.06; 95% CI, 1.30-7.18; P = .010). The outcome of relapsed/refractory patients was very poor, and CNS involvement was not associated with a significantly worse outcome compared with relapsed/refractory patients without CNS involvement in multivariable analysis (HR, 1.6; 95% CI, 0.96-2.6; P = .074). The results from the present study indicate that CNS relapse in PTCL occurs at a frequency similar to what is seen in aggressive B-cell lymphomas, but the poor outcomes in relapse are largely driven by systemic rather than CNS disease. © 2015 by The American Society of Hematology.

Once-daily oral fingolimod is approved in the EU as escalation treatment for adult patients with highly active relapsing multiple sclerosis (MS). The efficacy and safety profiles of fingolimod have been well established in a large clinical development programme and several papers reflecting the experience with fingolimod in real-world settings have been published to date. The GOLEMS study was designed to evaluate the efficacy, safety and tolerability of fingolimod and the impact of fingolimod treatment on disability progression and work capability in patients with MS in routine clinical practice in the Czech Republic. GOLEMS was a national, multicentre, non-interventional, single-arm study conducted to analyse the outcomes of a minimum of 12 months of fingolimod therapy on primary and secondary endpoints. The primary endpoint was to assess the proportion of relapse-free patients and severity of MS relapses in patients treated with fingolimod for 12 months. Secondary endpoints included assessment of changes in disability progression evaluated by the Expanded Disability Status Scale (EDSS) score and work capability assessment measured through voluntary completion of the WPAI-GH questionnaire. The predictive factors for relapse-free status during fingolimod treatment were also analysed. Of the 240 enrolled patients, 219 completed the 12-month treatment period at the time of final analysis. In the efficacy set (N = 237), the proportion of relapse-free patients increased from 47 patients (19.6 %; 95 % confidence interval [CI] 14.8-25.2) in the year before fingolimod initiation to 152 patients (64.1 %; 95 % CI 58.0-70.2) after 1 year of fingolimod treatment. Of the 85 patients who experienced at least one relapse after 1 year of fingolimod treatment, 53 (62.4 %; 95 % CI 51.7-71.9) reported only one relapse, while 25 (29.4 %; 95 % CI 20.8-39.8) and seven (8.2 %; 95 % CI 4.0-16.0) patients had ≥2 relapses, respectively. No significant changes were observed in EDSS scores over the 12-month treatment period compared with baseline. The absolute number of relapses during 2 years before initiation of fingolimod treatment and baseline EDSS scores were identified as significant independent predictors for 'being relapse-free' during the 12-month fingolimod treatment period. No trend was established in work capability or number of missed days at work due to the large proportion of missing data. Of 240 enrolled patients, 27 (11.3 %) patients discontinued the study at or before the 12-month visit, 16 (6.7 %) discontinued because of adverse events related to study drug. Only six (2.5 %) patients reported serious adverse events related to the study drug. The results confirm the favourable safety and efficacy profile of fingolimod under real-world conditions, consistent with phase III trials.

The association between cytomegalovirus (CMV) reactivation and relapse risk has not been evaluated in relation to T cell depletion strategies. We evaluated 93 patients who underwent allogeneic hematopoietic stem cell transplantation (HSCT) and analyzed the association between T cell depletion strategies with the cumulative incidence of relapse and CMV reactivation. A total of 33% of patients who received ATG vs. 34% who received alemtuzumab developed CMV reactivation. The cumulative incidence of relapse was 3% at 1year and 20% at 3 years in patients with CMV reactivation vs. 30% at 1year and 38% at 3 years in patients without CMV reactivation (p=0.02). When analyzed separately, this effect persisted in the myeloid, but not the lymphoid group. There was a numerical trend towards increased non-relapse mortality (NRM) in patients with CMV reactivation, especially in the myeloid group. The choice of T cell depleting agent and the rate of CMV reactivation were not associated with different overall survival (OS) rates. These results suggest that the choice of T cell depletion strategy may have similar effects on rates of CMV reactivation, disease relapse, and survival. Further studies examining these variables in patients not exposed to in-vivo T cell depleting agents may be of interest. Copyright © 2017 Elsevier Ltd. All rights reserved.

We aimed to ascertain the feasibility and safety of NA cessation, the status of patients after cessation, and the predictive factors for relapse and subsequent retreatment. A total of 92 patients were enrolled in this prospective study. Patients were monitored every month for the first 3 months after cessation and every 3 months thereafter. Sixty-two patients finished 48 weeks of follow-up. None died or developed liver failure, cirrhosis, or HCC. The 62 patients could be divided into 4 categories according to the 48-week clinical development of relapse. Virologic relapses occurred in 39 (62.9%) patients, with 72.7% occurring in the first 24 weeks in origin HBeAg positive patients and 82.4% in the first 12 weeks in origin HBeAg negative patients. Age (OR = 1.06, 95% CI = 1.02-1.10; p = 0.003), the HBsAg level (OR = 2.21, 95% CI = 1.47-3.32; p < 0.001), and positive origin HBeAg status (OR = 0.32, 95% CI = 0.14-0.74; p = 0.008) were predictive factors to virologic relapse. HBV DNA level (OR = 1.34, 95% CI = 1.13-1.58; p < 0.001) was predictive factor to retreatment. NA cessation is safe under supervision. Age, HBsAg level, and origin HBeAg status can be predictive factors for virologic relapse. The study was submitted to ClinicalTrials.gov Protocol Registration and Results System with the assigned NCT ID NCT02883647.

Antithyroid drugs are widely used in the treatment of Graves' disease (GD), but the relapse rate is very high after therapy withdrawal. We evaluated the reduction effects of intrathyroid injection of dexamethasone (IID) on the relapse rate of hyperthyroidism in patients with newly diagnosed GD. A total of 191 patients with GD completed the study. After 6 months of treatment with methimazole (MMI), the patients were randomly assigned to receive either MMI (96 patients) alone or MMI combined with IID (MMI+IID; 95 patients) treatment for 3 months, followed by continuing a dose of MMI that would maintain euthyroidism for the next 9 months in all of the patients. After withdrawal of the medical therapy, patients were followed for 24 months, and the relapse rate of hyperthyroidism was evaluated. No statistical difference was observed in the levels of serum FT(4), TSH, or TSH receptor antibodies (TR-Ab), the thyroid volume, or the TR-Ab positive rate between the two groups at month 6. After the next 3 months of treatment with MMI+IID or MMI alone, the levels of TSH increased significantly, and the levels of serum TR-Ab, the TR-Ab positive rate, and thyroid volume decreased significantly in the MMI+IID group compared with the MMI group. Seven patients (7.4%) experienced a relapse of overt hyperthyroidism in the MMI+IID group and 49 patients (51%) in MMI group during the 2-yr follow-up period (P < 0.001). MMI+IID treatment is helpful to prevent relapse of hyperthyroidism in GD after medical therapy withdrawal.

Treatment of patients with relapsed or refractory lymphoma may require allogenic hematopoietic stem cell transplant (HSCT), but treatment of post-transplant relapse disease remains very challenging. Donor lymphocyte infusion and blinatumomab have been used with limited success for the treatment of relapse. Initial data on donor-derived CAR T cells has shown this modality to be safe and highly effective in various hematological malignancies. We present a case of a patient with highly refractory, transformed follicular lymphoma who failed both autologous and allogenic HSCT. Patient achieved long-lasting complete remission with the use of donor origin CD19 CAR T-cell therapy, without any evidence of graft-versus-host disease flare. Our patient later developed disseminated coccidioidomycosis and persistent hypogammaglobulinemia. Immunotherapy using CD19 CAR T cells can be a highly effective salvage modality, especially in cases of focal lymphoma relapse. Long-term immunosuppression secondary to B cell lymphopenia, hypogammaglobulinemia, immunoglobulin subclass deficiency, fungal infections and other infectious complications need to be monitored and promptly treated as indicated.

Background For patients with Graves’ disease (GD), the primary goal of antithyroid drug therapy is to temporarily restore the patient to the euthyroid state and wait for a subsequent remission of the disease. This study sought to identify the predictive markers for the relapse of disease. Methods To do this, we studied 262 GD patients with long enough follow-up after drug withdrawal to determine treatment outcome. The patients were divided into three groups by time of relapse: early relapse group (n = 91) had an early relapse within 9 months, late relapse group (n = 65) had a relapse between 10 and 36 months, and long-term remission group (n = 106) were either still in remission after at least 3 years or relapsed after 3 years of drug withdrawal. We assessed the treatment outcome of 23 SNPs of costimulatory genes, phenotype and smoking habits. We used permutation to obtain p values for each SNP as an adjustment for multiple testing. Cox proportional hazards models was performed to assess the strength of association between the treatment outcome and clinical and laboratory variables. Results Four SNPs were significantly associated with disease relapse: rs231775 (OR 1.96, 95% CI 1.18–3.26) at CTLA-4 and rs745307 (OR 7.97, 95% CI 1.01–62.7), rs11569309 (OR 8.09, 95% CI 1.03–63.7), and rs3765457 (OR 2.60, 95% CI 1.08–6.28) at CD40. Combining risk alleles at CTLA-4 and CD40 improved the predictability of relapse. Using 3 years as the cutoff point for multivariate analysis, we found several independent predictors of disease relapse: number of risk alleles (HR 1.30, 95% CI 1.09–1.56), a large goiter size at the end of the treatment (HR 1.30, 95% CI 1.05–1.61), persistent TSH-binding inhibitory Ig (HR 1.64, 95% CI 1.15–2.35), and smoking habit (HR 1.60, 95% CI 1.05–2.42). Conclusion Genetic polymorphism of costimulatory genes, smoking status, persistent goiter, and TSH-binding inhibitory Ig predict disease relapse. PMID:24783027

Purpose We sought to determine whether cranial radiotherapy (CRT) is necessary to prevent relapse in any subgroup of children with acute lymphoblastic leukemia (ALL). Patients and Methods We obtained aggregate data on relapse and survival outcomes for 16,623 patients age 1 to 18 years old with newly diagnosed ALL treated between 1996 and 2007 by 10 cooperative study groups from around the world. The proportion of patients eligible for prophylactic CRT varied from 0% to 33% by trial and was not related to the proportion eligible for allogeneic stem-cell transplantation in first complete remission. Using a random effects model, with CRT as a dichotomous covariate, we performed a single-arm meta-analysis to compare event-free survival and cumulative incidence of isolated or any CNS relapse and isolated bone marrow relapse in high-risk subgroups of patients who either did or did not receive CRT. Results Although there was significant heterogeneity in all outcome end points according to trial, CRT was associated with a reduced risk of relapse only in the small subgroup of patients with overt CNS disease at diagnosis, who had a significantly lower risk of isolated CNS relapse (4% with CRT v 17% without CRT; P = .02) and a trend toward lower risk of any CNS relapse (7% with CRT v 17% without CRT; P = .09). However, this group had a relatively high rate of events regardless of whether or not they received CRT (32% [95% CI, 26% to 39%] v 34% [95% CI, 19% to 54%]; P = .8). Conclusion CRT does not have an impact on the risk of relapse in children with ALL treated on contemporary protocols. PMID:26755523

We compared the relative efficacy of interferon beta (IFNbeta) products and azathioprine (AZA) in the treatment of relapsing- remitting multiple sclerosis (RRMS). Ninety-four previously untreated patients of short duration with RRMS were randomly allocated to the two treatment groups. The first group received IFNbeta products (Betaferon,Avonex or Rebif); the second group received AZA for 12 months. Response to treatment was assessed at 3, 6, and 12 months after starting therapy. The mean number of relapse during one year of the study was lower in the AZA group than in the IFNbeta products group (0.28 vs. 0.64, P < 0.05). After 12 months, 57.4% of patients receiving IFNbeta products remained relapse free compared with 76.6% of those given AZA. The Expanded Disability Status Scale (EDSS) decreased by 0.30 units in IFNbeta-treated patients (P < 0.05) and 0.46 in AZAtreated patients (P < 0.001). Treatment with IFNbeta products and AZA significantly reduces the relapse rate and EDSS score in patients with RRMS, while AZA is more effective than the IFNbeta formulations.

Refractory and relapsing crytocococcosis in acquired immune deficiency syndrome (AIDS) patients have a poor prognosis. The risk factors for this complicated infection course were evaluated by comparing refractory and/or relapsing cryptococcosis in human immunodeficiency virus-coinfected patients (cohort 1) with another group of AIDS patients who adequately responded to antifungals (cohort 2). Except for one isolate of Cryptococcus gattii from a cohort 2 case, all other isolates were identified as Cryptococcus neoformans var. grubii, sex type α, genotype VNI, including Cryptococcus reisolated from the relapse or in the refractory state. No differences were observed with respect to Cryptococcus capsule size and in the melanin and phospholipase production. The cohort 1 patients presented higher prevalence of cryptococcemia, cerebral dissemination, chronic liver disease, and leucopenia, and have increased death rate. Apparently, the refractory and/or relapsing cryptococcosis in the AIDS patients were more related to the host and the extent of the infection than to the fungal characteristics. © The American Society of Tropical Medicine and Hygiene.

The fludarabine, amsacrine, and cytarabine (FLAMSA)-reduced-intensity conditioning (RIC) protocol has been described to be effective in patients with high-risk and refractory acute myeloic leukemia (AML) undergoing allogeneic hematopoietic stem cell transplantation (aSCT). To increase safety and tolerability of the conditioning, we previously reported the feasibility to substitute the TBI component by treosulfan in elderly AML patients. We now present long-term follow-up data on patients treated with FLAMSA/treosulfan compared to the original FLAMSA/4Gy TBI protocol. We retrospectively analyzed 130 consecutive patients with high-risk or relapsed AML after aSCT following FLAMSA conditioning at our center. Fifty-eight patients were treated with FLAMSA/treosulfan due to age and/or comorbidities. Seventy-two patients were treated with FLAMSA/TBI. Median age of patients treated with FLAMSA/treosulfan was 60 years compared to 46 years in those treated with FLAMSA/TBI. The cumulative incidence of a non-relapse mortality at 4 years was 28% in FLAMSA/treosulfan patients as compared to 13% in FLAMSA/TBI. Cumulative incidence of relapse was higher in patients treated with FLAMSA/TBI (46 vs. 32%). This difference was even more prominent for patients treated in blast persistence prior to transplant (relapse incidence 70% for TBI vs. 35% for treosulfan). The overall and relapse-free survival rates at 4 years were 47 and 41%, respectively, for patients treated with FLAMSA/TBI as compared to 43 and 40% in patients treated with FLAMSA/treosulfan. These data indicate an anti-leukemic activity by FLAMSA/treosulfan especially in patients with a blast persistence prior to transplant. Older age was an independent factor for a higher non-relapse mortality. Translating FLAMSA/treosulfan to younger patients, a lower non-relapse mortality, and an improved anti-leukemic activity might add up to improved overall survival. Randomized studies are required to demonstrate an improved efficacy of treosulfan- versus TBI-based FLAMSA conditioning.

This pilot study has been designed to collect preliminary data on the use of a new antiepileptic drug in the management of alcoholic patients. Oxcarbazepine (OXC) blocks voltage-sensitive sodium channels. Its metabolite reduces high-voltage-activated calcium currents in striatal and cortical neurons, thus reducing glutamatergic transmission at corticostriatal synapses. This reduction is of interest in the treatment of alcohol dependence, as acamprosate (ACP) modulates NMDA receptors, resulting in an inhibition of glutamatergic transmission. Furthermore, OXC has revealed a mood-stabilizing effect in bipolar affective disorders. We have compared OXC with ACP in relapse prevention in recently withdrawn alcohol-dependent patients. We investigated the efficacy and safety of OXC (vs ACP) by conducting a 24-week randomized, parallel-group, open-label, clinical trial on 30 acutely detoxified alcoholic patients. Survival analyses (Kaplan-Meier) were performed to look for evidence of a longer "survival" of patients receiving OXC. We assessed time to first severe relapse and additional secondary endpoints. After withdrawal, time to severe relapse and time to first consumption of any ethanol by OXC patients were not longer than for ACP patients. Abstinent patients in both study groups showed a significantly lower obsessive compulsive drinking scale-German version (OCDS-G) than relapsed patients. No undesired effects occurred when OXC patients consumed alcohol. Our findings indicate that it could be worthwhile to test relapse prevention using OXC in an adequate sample. While the current sample size clearly limits further conclusions from this pilot study, it is noteworthy that OXC is well tolerated, even when alcohol is on board. Thus, in medication-based relapse prevention, OXC could be a promising alternative for alcoholic patients unable to benefit from ACP or naltrexone or those who have affective liability. OXC certainly merits a larger placebo-controlled trial.

Gemtuzumab ozogamicin (fGO), a humanized anti-CD33 monoclonal antibody linked to calicheamicin in combination with intensive chemotherapy gives high response rates in adult acute myeloid leukemia (AML) patients in relapse. However, reduced intensity chemotherapy in combination with fractionated GO has not been tested in aged relapsing patients. Patients from our institution with CD33+ AML aged 55 years or more in first late relapse (≥ 6 months) were proposed participation in a GO compassionate use program. Induction therapy consisted in fractionated GO (fGO; 3 mg/m², days 1, 4, 7) with standard-dose cytarabine (200 mg/m² /day, 7 days). Patients were consolidated with two courses of GO and intermediate dose cytarabine. Twenty-four patients (median age 68 years) received fGO with cytarabine. Median follow-up was 42 months. The response rate was 75%, including complete remission (CR) in 16 patients and CR with incomplete platelet recovery (CRp) in two patients. Two-year overall survival (OS) was 51% (95% CI: 28-69) and 2 years relapse-free survival (RFS) was 51% (95%CI: 25-72). Duration of second CR (CR2) was longer than first CR (CR1) in 9 out of 18 patients. Minimal residual disease (MRD) was negative in evaluable patients in CR2, particularly in NPM1 mutated cases. Toxicity was in line with that of the same fractionated single agent GO schedule. Fractionated GO with low intensity chemotherapy produced high response rates and prolonged CR2 in aged AML patients in first late relapse. Copyright © 2013 Wiley Periodicals, Inc.

Continued smoking after a cancer diagnosis contributes to several negative health outcomes. Although many cancer patients attempt to quit smoking, high smoking relapse rates have been observed. This highlights the need for a targeted, evidence-based smoking-relapse prevention intervention. The design, method, and baseline characteristics of a randomized controlled trial assessing the efficacy of a self-help smoking-relapse prevention intervention are presented. Cancer patients who had recently quit smoking were randomized to one of two conditions. The Usual Care (UC) group received the institution's standard of care. The smoking relapse-prevention intervention (SRP) group received standard of care, plus 8 relapse-prevention booklets mailed over a 3month period, and a targeted educational DVD developed specifically for cancer patients. Four hundred and fourteen participants were enrolled and completed a baseline survey. Primary outcomes will be self-reported smoking status at 6 and 12-months after baseline. Biochemical verification of smoking status was completed for a subsample. If found to be efficacious, this low-cost intervention could be easily disseminated with significant potential for reducing the risk of negative cancer outcomes associated with continued smoking.

The cytogenetic data for 126 patients with Ph-positive chronic myelogenous leukemia (CML) in accelerated phase or blast crisis were analysed for clonal chromosomal abnormalities in addition to the standard Ph prior to allogeneic or syngeneic bone marrow transplantation (BMT). Additional clonal abnormalities were found in 84%, and 14% had a variant Ph (VPh). In decreasing order of frequency, the most common clonal abnormalities were a second Ph, +8, i(17q), -Y and +19. A second Ph, VPh or +8 occurred more frequently in patients who relapsed following BMT than in those who survived disease-free for at least 1 1/2 years. The presence of an i(17q) alone did not correlate with relapse. The patients with a second Ph, VPh or +8 had a median time to relapse of 19 months, and the risk of relapse at 3 years was 73%. Those with other or no additional clonal abnormalities had not reached a median time to relapse and had a 3-year risk of relapse of 31% (p = 0.002). This analysis suggests that specific cytogenetic abnormalities may be useful indicators of resistance to therapy for CML and should be included in proportional hazard models to predict outcome after BMT.

Although steady improvements to chemotherapeutic treatments has helped cure 80% of childhood acute lymphoblastic leukemia (ALL) cases, chemotherapy has proven to be less effective in treating the majority of adult patients, leaving allogeneic hematopoietic stem cell transplantation (allo-HSCT) as the primary adult treatment option. Nevertheless relapse are the leading cause of death following allo-HSCT. The genetic pathogenesis of relapse following allo-HSCT in Philadelphia chromosome- negative ALL (Ph- ALL) remains unexplored. We performed longitudinal whole-exome sequencing analysis in three adult patients with Ph- B-cell ALL (Ph- B-ALL) on samples collected from diagnosis to relapse after allo-HSCT. Based on these data, we performed target gene sequencing on 23 selected genes in 58 adult patients undergoing allo-HSCT with Ph- B-ALL. Our results revealed a significant enrichment of mutations in epigenetic regulators from relapsed samples, with recurrent somatic mutations in SETD2, CREBBP, KDM6A and NR3C1. The relapsed samples were also enriched in signaling factor mutations, including KRAS, PTPN21, MYC and USP54. Furthermore, we are the first to reveal the clonal evolution patterns during leukemia relapse after allo-HSCT. Cells present in relapsed specimens were genetically related to the diagnosed tumor, these cells therefore arose from either an existing subclone that was not eradicated by allo-HSCT therapy, or from the same progenitor that acquired new mutations. In some cases, however, it is possible that leukemia recurrence following allo-HSCT could result from a secondary malignancy with a distinct set of mutations. We identified novel genetic causes of leukemia relapse after allo-HSCT using the largest generated data set to date from adult patients with Ph- B-ALL.

Cetani, Giusy; Boccadoro, Mario; Oliva, Stefania

2018-05-16

Multiple myeloma treatment considerably improved during the past decade, thanks to novel effective drugs, a better understanding of myeloma biology and clonal heterogeneity, and an improved management of toxicities. The choice of regimen at relapse is usually based on prior response, toxicities, age and comorbidities of relapsed patients. Areas covered: A review was performed of the most recent and effective therapeutic strategies for the relapsed myeloma setting, by documenting the latest clinical evidence from phase II and III clinical trials. Of note, new drugs, such as carfilzomib, ixazomib, pomalidomide, daratumumab and elotuzumab, alone or in combinations in doublet or triplet regimens, have greatly increased the treatment armamentarium against myeloma. Expert Commentary: Impressive results have been obtained with new drugs in relapsed patients. Besides number of prior therapies and previous response, other factors play a crucial role in the selection of therapy. Re-challenge with previous drugs can be adopted if previous responses lasted at least 6 months and therapy had induced low toxicity. Patients' risk status can further help to appropriately select therapy at relapse, and clinical trials will allow physicians to use newer targeted therapies and immune-therapies, thus delaying palliative approaches to later relapse stages.

[Relapse: causes and consequences].

Relapse after a first episode of schizophrenia is the recurrence of acute symptoms after a period of partial or complete remission. Due to its variable aspects, there is no operational definition of relapse able to modelise the outcome of schizophrenia and measure how the treatment modifies the disease. Follow-up studies based on proxys such as hospital admission revealed that 7 of 10 patients relapsed after a first episode of schizophrenia. The effectiveness of antipsychotic medications on relapse prevention has been widely demonstrated. Recent studies claim for the advantages of atypical over first generation antipsychotic medication. Non-adherence to antipsychotic represents with addictions the main causes of relapse long before some non-consensual factors such as premorbid functioning, duration of untreated psychosis and associated personality disorders. The consequences of relapse are multiple, psychological, biological and social. Pharmaco-clinical studies have demonstrated that the treatment response decreases with each relapse. Relapse, even the first one, will contribute to worsen the outcome of the disease and reduce the capacity in general functionning. Accepting the idea of continuing treatment is a complex decision in which the psychiatrist plays a central role besides patients and their families. The development of integrated actions on modifiable risk factors such as psychosocial support, addictive comorbidities, access to care and the therapeutic alliance should be promoted. Relapse prevention is a major goal of the treatment of first-episode schizophrenia. It is based on adherence to the maintenance treatment, identification of prodromes, family active information and patient therapeutical education. Copyright © 2013 L’Encéphale.

Despite improvements in first-line therapies, the outcomes of relapsed or refractory childhood acute leukaemia that has not achieved complete remission after relapse, has relapsed after stem cell transplantation (SCT), has primary induction failure and has relapsed with a very unfavourable cytogenetic risk profile, are dismal. We evaluated the feasibility and efficacy of T-cell-replete haploidentical peripheral blood stem cell transplantation (haplo-SCT) with low-dose anti-human thymocyte immunoglobulin (ATG), tacrolimus, methotrexate and prednisolone (PSL) in 14 paediatric patients with high-risk childhood acute leukaemia. All patients achieved complete engraftment. The median time to reaching an absolute neutrophil count of more than 0.5 × 10(9) L(-1) was 14 days. Acute graft-vs-host disease (aGVHD) of grades II-IV and III-IV developed in 10 (71%) and 2 (14%) patients, respectively. Treatment-related mortality and relapse occurred in one (7%) patient and six (43%) patients, respectively. Eleven patients were alive and seven of them were disease-free with a median follow-up of 36 months (range: 30-159 months). The probability of event-free survival after 2 years was 50%. These findings indicate that T-cell-replete haplo-SCT, with low-dose ATG and PSL, provides sustained remission with an acceptable risk of GVHD in paediatric patients with advanced haematologic malignancies. © 2014 The Authors.

A proportion of patients with aplastic anemia who are treated with immunosuppressive therapy develop clonal hematologic disorders, including post-aplastic anemia myelodysplastic syndrome. Many will proceed to allogeneic hematopoietic stem cell transplantation. We identified 123 patients with post-aplastic anemia myelodysplastic syndrome who from 1991 through 2011 underwent allogeneic hematopoietic stem cell transplantation, and in a matched-pair analysis compared outcome to that in 393 patients with de novo myelodysplastic syndrome. There was no difference in overall survival. There were no significant differences with regard to 5-year probabilities of relapse, non-relapse mortality, relapse-free survival and overall survival; these were 14%, 40%, 46% and 49% for post-aplastic anemia myelodysplastic syndrome, and 20%, 33%, 47% and 49% for de novo myelodysplastic syndrome, respectively. In multivariate analysis, relapse (hazard ratio 0.71; P=0.18), non-relapse mortality (hazard ratio 1.28; P=0.18), relapse-free survival (hazard ratio 0.97; P=0.80) and overall survival (hazard ratio 1.02; P=0.88) of post-aplastic anemia myelodysplastic syndrome were similar to those of patients with de novo myelodysplastic syndrome. Cytogenetic risk was independently associated with overall survival in both groups. Thus, transplant success in patients with post-aplastic anemia myelodysplastic syndrome was similar to that in patients with de novo myelodysplastic syndrome, and cytogenetics was the only significant prognostic factor for post-aplastic anemia myelodysplastic syndrome patients.

Acquired idiopathic thrombotic thrombocytopenic purpura (I-TTP) is a life-threatening microangiopathic disorder usually treated with therapeutic plasma exchange (TPE). The current study assessed the role of rituximab in the treatment of complicated I-TTP. The sequence of TTP events was compared in a group of I-TTP patients treated with TPE and a cohort of refractory or relapsed patients who also received rituximab. This retrospective evaluation included 45 I-TTP patients, treated between January 2000 and October 2013, who underwent at least 3 TPE procedures and were followed up until December 2013 or death. Thirty-one patients with an uncomplicated course received TPE only. Fourteen patients had a complicated course due to either a primary refractory/exacerbated disease (n = 5) or relapse (n = 9) and received rituximab together with TPE. The median number of TPE procedures performed in the first TTP episode in the uncomplicated cohort and groups with primary refractory or relapsed TTP was 11, 27 and 45, respectively. The relapse rates per follow-up year in the uncomplicated I-TTP, primary refractory and relapsed I-TTP groups were 0.18, 0.2 and 0.6 episodes, respectively. After rituximab therapy this rate dropped to 0.2 per year in the relapsed subgroup. In conclusion, about a quarter of patients with I-TTP had a complicated course and experienced a major benefit from rituximab in terms of effectiveness and safety. © 2015 S. Karger AG, Basel.

Objectives  To examine the risk of relapse and time to relapse after discontinuation of antidepressants in patients with anxiety disorder who responded to antidepressants, and to explore whether relapse risk is related to type of anxiety disorder, type of antidepressant, mode of discontinuation, duration of treatment and follow-up, comorbidity, and allowance of psychotherapy. Design  Systematic review and meta-analyses of relapse prevention trials. Data sources  PubMed, Cochrane, Embase, and clinical trial registers (from inception to July 2016). Study selection  Eligible studies included patients with anxiety disorder who responded to antidepressants, randomised patients double blind to either continuing antidepressants or switching to placebo, and compared relapse rates or time to relapse. Data extraction  Two independent raters selected studies and extracted data. Random effect models were used to estimate odds ratios for relapse, hazard ratios for time to relapse, and relapse prevalence per group. The effect of various categorical and continuous variables was explored with subgroup analyses and meta-regression analyses respectively. Bias was assessed using the Cochrane tool. Results  The meta-analysis included 28 studies (n=5233) examining relapse with a maximum follow-up of one year. Across studies, risk of bias was considered low. Discontinuation increased the odds of relapse compared with continuing antidepressants (summary odds ratio 3.11, 95% confidence interval 2.48 to 3.89). Subgroup analyses and meta-regression analyses showed no statistical significance. Time to relapse (n=3002) was shorter when antidepressants were discontinued (summary hazard ratio 3.63, 2.58 to 5.10; n=11 studies). Summary relapse prevalences were 36.4% (30.8% to 42.1%; n=28 studies) for the placebo group and 16.4% (12.6% to 20.1%; n=28 studies) for the antidepressant group, but prevalence varied considerably across studies, most likely owing to differences in the length of follow-up. Dropout was higher in the placebo group (summary odds ratio 1.31, 1.06 to 1.63; n=27 studies). Conclusions  Up to one year of follow-up, discontinuation of antidepressant treatment results in higher relapse rates among responders compared with treatment continuation. The lack of evidence after a one year period should not be interpreted as explicit advice to discontinue antidepressants after one year. Given the chronicity of anxiety disorders, treatment should be directed by long term considerations, including relapse prevalence, side effects, and patients' preferences.

Patients with 2000 FIGO low-risk gestational trophoblastic neoplasia are commonly treated with single-agent chemotherapy. Methotrexate is widely used in this indication in Europe. Analysis of relapse after treatment and identification of factors associated with relapse would help understand their potential impacts on 2000 FIGO score evolution and chemotherapy management of gestational trophoblastic neoplasia patients. This retrospective study analyzes the predictive factors of relapse in low-risk gestational trophoblastic neoplasia patients whose hormone chorionic gonadotropin (hCG) normalized with methotrexate alone. Between 1999 and 2014, 993 patients with gestational trophoblastic neoplasia were identified in the French Trophoblastic Disease Reference Center database, of which 465 were low-risk patients whose hCG normalized with methotrexate alone. Using univariate and multivariate analysis we identified significant predictive factors for relapse after methotrexate. The Kaplan-Meier method was used to plot the outcome of patients. The 5-year recurrence rate of low-risk gestational trophoblastic neoplasia patients whose hCG normalized with methotrexate alone was 5.7% (confidence interval [IC], 3.86-8.46). Univariate analysis identified an antecedent pregnancy resulting in a delivery (HR = 5.96; 95% CI, 1.40-25.4, P = .016), a number of methotrexate courses superior to 5 courses (5-8 courses vs 1-4: HR = 6.19; 95% CI, 1.43-26.8, P = .015; 9 courses and more vs 1-4: HR = 6.80; 95% CI, 1.32-35.1, P = .022), and hCG normalization delay centered to the mean as predictive factors of recurrence (HR = 1.27; 95% CI, 1.09-1.49, P = .003). Multivariate analysis confirmed the type of antecedent pregnancy and the number of methotrexate courses as independent predictive factors of recurrence. A low-risk gestational trophoblastic neoplasia arising after a normal delivery had an 8.66 times higher relapse risk than that of a postmole gestational trophoblastic neoplasia (95% CI, 1.98-37.9], P = .0042). A patient who received 5-8 courses of methotrexate had a 6.7 times higher relapse risk than a patient who received 1-4 courses (95% CI, 1.54-29.2, P = .011). A patient who received 9 courses or more had an 8.1 times higher relapse risk than a patient who received 1-4 courses of methotrexate (95% CI, 1.54-42.6, P = .014). Low-risk gestational trophoblastic neoplasia following a delivery and patients who need more than 4 courses of methotrexate to normalization are at a higher risk of relapse than other low-risk patients. Allotting a higher score to the "antecedent pregnancy" FIGO item should be considered for postdelivery gestational trophoblastic neoplasia. Further analysis of the need for consolidation courses is warranted. Copyright © 2016 Elsevier Inc. All rights reserved.

Multidrug-resistant tuberculosis (MDR-TB) is a major obsession for TB control. The main risk factor for MDR-TB remains a history of TB treatment especially bad conduct. The objective of this study is to describe the profile of patients in situations of failure and relapse of tuberculosis. We performed a retrospective survey of the analysis of records of patients starting TB retreatment for failure or relapse of tuberculosis. We used 193 cases with results of culture-sensitivity. The proportion of failure is 59/193 (30.6 %) and cases of relapse are 134/193 (69.4 %). The proportion of married life is 23.4 % (11/47) in chess against 41.5 % (51/123) in relapse of TB [P=0.021, OR=0.431 (0.201 to 0.927)]. Patients failing therapy have more chest pain [5.8 % (3/52) versus 0 % (0/126) with P=0.024]. The proportion of MDR-TB was 61.4 (38/59) in case of failure against 41 % (55/134) in case of relapse [P=0.002, OR=2.599 (1.378 to 4.902)]. The evolution is the same whatever the indication of reprocessing. The proportion of MDR-TB is very important in case of reprocessing failure and relapse of tuberculosis.

From March, 1976 to February, 1979, 28 cases of adult acute leukemia of which 24 were evaluable were treated in irreversible relapse with high dose chemotherapy (piperazinedione) and supra-lethal total body irradiation (TBI) in conjunction with autologous bone marrow transplantation (ABMT). The marrow cells grafted were collected and stored in liquid nitrogen at the time of remission. In 12 patients the marrow cells were fractionated using discontinuous albumin gradients in an attempt to separate normal cells from residual leukemic cells. Twelve patients achieved complete remission (CR); in 9 additional patients signs of engraftment were evident but death occurred before achievement of CR. Seven of 12 AML patients, which were treated with bone marrow transplantation as first treatment of their relapse, achieved CR. Four of 5 patients with ALL, whose bone marrows were collected during first remission, reached CR. The median CR duration was 4+ months and the median survival of the patients reaching CR was 6+ months. Autologous bone marrow transplantation offers a good chance of CR (66%), when marrow is collected during first remission and used as first treatment for AML in third relapse and ALL in second relapse.

The purpose of this study was to assess the outcomes of 118 patients with eosinophilic granulomatosis with polyangiitis (EGPA) enrolled in 2 prospective, randomized, open-label clinical trials (1994-2005), with or without Five-Factor Score (FFS)-defined poor-prognosis factors, focusing on survival, disease-free survival, relapses, clinical and laboratory findings, therapeutic responses, and factors predictive of relapse. Forty-four patients with FFS ≥ 1 were assigned to receive 6 or 12 cyclophosphamide pulses plus corticosteroids and the seventy-four with FFS = 0 received corticosteroids alone, with immunosuppressant adjunction when corticosteroids failed. Patients were followed (2005-2011) under routine clinical care in an extended study and data were recorded prospectively. Mean ± SD follow-up was 81.3 ± 39.6 months. Among the 118 patients studied, 29% achieved long-term remission and 10% died. Among the 115 patients achieving a first remission, 41% experienced ≥1 relapses, 26.1 ± 26.8 months after treatment onset, with 57% of relapses occurring when corticosteroid-tapering reached <10 mg/day. Treatment achieved new remissions in >90%, but relapses recurred in 38%. Overall survival was good, reaching 90% at 7 years, regardless of baseline severity. Age ≥65 years was the only factor associated with a higher risk of death during follow-up. The risk of relapse was higher for patients with anti-myeloperoxidase antibodies and lower for those with >3000 eosinophils/mm(3). Sequelae remained frequent, usually chronic asthma and peripheral neuropathy. In conclusion, EGPA patients' survival rate is very good when treatment is stratified according to the baseline FFS. Relapses are frequent, especially in patients with anti-myeloperoxidase antibodies and baseline eosinophilia <3000/mm(3). Copyright © 2013 Elsevier Ltd. All rights reserved.

B cells are attracting increasing attention in the pathogenesis of multiple sclerosis (MS). B cell-targeted therapies with monoclonal antibodies or plasmapheresis have been shown to be successful in a subset of patients. Here, patients with either relapsing-remitting (n = 24) or secondary progressive (n = 6) MS presenting with an acute clinical relapse were screened for their B cell reactivity to brain antigens and were re-tested three to nine months later. Enzyme-linked immunospot technique (ELISPOT) was used to identify brain-reactive B cells in peripheral blood mononuclear cells (PBMC) directly ex vivo and after 96 h of polyclonal stimulation. Clinical severity of symptoms was determined using the Expanded Disability Status Scale (EDSS). Nine patients displayed B cells in the blood producing brain-specific antibodies directly ex vivo. Six patients were classified as B cell positive donors only after polyclonal B cell stimulation. In 15 patients a B cell response to brain antigens was absent. Based on the autoreactive B cell response we categorized MS relapses into three different patterns. Patients who displayed brain-reactive B cell responses both directly ex vivo and after polyclonal stimulation (pattern I) were significantly younger than patients in whom only memory B cell responses were detectable or entirely absent (patterns II and III; p = 0.003). In one patient a conversion to a positive B cell response as measured directly ex vivo and subsequently also after polyclonal stimulation was associated with the development of a clinical relapse. The evaluation of the predictive value of a brain antigen-specific B cell response showed that seven of eight patients (87.5%) with a pattern I response encountered a clinical relapse during the observation period of 10 months, compared to two of five patients (40%) with a pattern II and three of 14 patients (21.4%) with a pattern III response (p = 0.0005; hazard ratio 6.08 (95% confidence interval 1.87-19.77). Our data indicate actively ongoing B cell-mediated immunity against brain antigens in a subset of MS patients that may be causative of clinical relapses and provide new diagnostic and therapeutic options for a subset of patients.

Post-marketing studies are important to confirm what was established in clinical trials, and to assess the intermediate and long-term efficacy and safety. To assess efficacy and safety of fingolimod in multiple sclerosis (MS) in Kuwait. We retrospectively evaluated MS patients using the MS registries in 3 MS clinics. Relapsing remitting MS patients according to revised 2010 McDonald criteria who had been treated with fingolimod for at least 12 months were included. Primary endpoint was proportion of relapse-free patients at last follow-up. Secondary endpoints were mean change in EDSS and proportion of patients with MRI activity (gadolinium-enhancing or new/enlarging T2 lesions). 76 patients met the inclusion criteria. Mean age and mean disease duration were 34.43 and 7.82 years respectively. Mean duration of exposure to fingolimod was 18.50 months. Proportion of relapse-free patients was 77.6% at last follow-up. Mean EDSS score significantly improved (2.93 versus 1.95; p<0.0001) while 17.1% of patients continued to have MRI activity versus 77.6% at baseline (p<0.0001). Four patients stopped fingolimod due to disease breakthrough (n=3) and lymphadenitis (n=1). Fingolimod is safe and effective in reducing clinical and radiological disease activity in relapsing remitting MS patients. Our results are comparable to reported results of phase III studies.

Subcutaneous pegylated interferon (peginterferon) beta-1a is being developed for treatment of relapsing multiple sclerosis, with less frequent dosing than currently available first-line injectable treatments. We assessed the safety and efficacy of peginterferon beta-1a after 48 weeks of treatment in the placebo-controlled phase of the ADVANCE trial, a study of patients with relapsing-remitting multiple sclerosis. We did this 2-year, double-blind, parallel group, phase 3 study, with a placebo-controlled design for the first 48 weeks, at 183 sites in 26 countries. Patients with relapsing-remitting multiple sclerosis (age 18-65 years, with Expanded Disability Status Scale score ≤5) were randomly assigned (1:1:1) via an interactive voice response or web system, and stratified by site, to placebo or subcutaneous peginterferon beta-1a 125 μg once every 2 weeks or every 4 weeks. The primary endpoint was annualised relapse rate at 48 weeks. This trial is registered with ClinicalTrials.gov, number NCT00906399. We screened 1936 patients and enrolled 1516, of whom 1512 were randomly assigned (500 to placebo, 512 to peginterferon every 2 weeks, 500 to peginterferon every 4 weeks); 1332 (88%) patients completed 48 weeks of treatment. Adjusted annualised relapse rates were 0·397 (95% CI 0·328-0·481) in the placebo group versus 0·256 (0·206-0·318) in the every 2 weeks group and 0·288 (0·234-0·355) in the every 4 weeks group (rate ratio for every 2 weeks group 0·644, 95% CI 0·500-0·831, p=0·0007; rate ratio for the every 4 weeks group 0·725, 95% CI 0·565-0·930, p=0·0114). 417 (83%) patients taking placebo, 481 (94%) patients taking peginterferon every 2 weeks, and 472 (94%) patients taking peginterferon every 4 weeks reported adverse events including relapses. The most common adverse events associated with peginterferon beta-1a were injection site reactions, influenza-like symptoms, pyrexia, and headache. 76 (15%) patients taking placebo, 55 (11%) patients taking study drug every 2 weeks, and 71 (14%) patients taking study drug every 4 weeks reported serious adverse events; relapse, pneumonia, and urinary tract infection were the most common. After 48 weeks, peginterferon beta-1a significantly reduced relapse rate compared with placebo. The drug might be an effective treatment for relapsing-remitting multiple sclerosis with less frequent administration than available treatments. Biogen Idec. Copyright © 2014 Elsevier Ltd.

Multiple myeloma (MM) is a heterogeneous disease with high-risk patients progressing rapidly despite treatment. Various definitions of high-risk MM are used and we reported that gene expression profile (GEP)-defined high risk was a major predictor of relapse. In spite of our best efforts, the majority of GEP70 high-risk patients relapse and we have noted higher relapse rates during drug-free intervals. This prompted us to explore the concept of less intense drug dosing with shorter intervals between courses with the aim of preventing inter-course relapse. Here we report the outcome of the Total Therapy 5 trial, where this concept was tested. This regimen effectively reduced early mortality and relapse but failed to improve progression-free survival and overall survival due to relapse early during maintenance.

Perceived Relapse Risk and Desire for Medication Assisted Treatment among Persons Seeking Inpatient Opiate Detoxification

Most patients with opioid addiction do not receive medication at the time of discharge from brief inpatient detoxification programs despite the high risk of relapse and the availability of three FDA-approved medications. We surveyed 164 inpatient opioid detoxification patients to assess desire for pharmacotherapy following detoxification program discharge. Participants were predominantly male (71.3%) and 80% had detoxed in the past. Reporting on their most recent previous inpatient detoxification, 27% had relapsed the day they were discharged, 65% within a month of discharge, and 90% within a year of discharge. 63% reported they wanted medication-assisted treatment (MAT) after discharge from the current admission. The odds of desiring a treatment medication increased by a factor of 1.02 for every 1% increase in perceived relapse risk (p < .01). These data suggest patient preference discussions including relapse risk could increase post-detox abstinence. PMID:23786852

A 79-year-old female with acute promyelocytic leukemia (APL) presented with second hematological relapse. She had been treated previously with modified AIDA protocol as the front-line therapy and had achieved complete remission. During ATRA maintenance therapy, the first hematological relapse occurred and she was treated with arsenic trioxide (ATO), achieving the second complete remission. After four courses of consolidation therapy of ATO, the second hematological relapse occurred. At this time, except for a transient effect of tamibarotene, neither arsenic trioxide nor combination chemotherapy was effective. The patient was then treated with two courses of gemtuzumab ozogamicin (GO) and achieved the third complete remission. At present, she is maintaining molecular remission more than one year after GO treatment. GO is considered to be a promising agent for elderly patients with relapsed acute promyelocytic leukemia resistant to arsenic trioxide.

Bullous pemphigoid (BP) is an autoimmune bullous skin disease characterized by anti-BP180 and anti-BP230 autoantibodies (AAbs). Mucous membrane involvement is an uncommon clinical feature of BP which may evoke epidermolysis bullosa acquisita, another skin autoimmune disease characterized by anti-type VII collagen AAbs. We therefore evaluated the presence of anti-type VII collagen AAbs in the serum of BP patients with and without mucosal lesions at time of diagnosis and under therapy. Anti-BP180, anti-BP230, and anti-type VII collagen AAbs were measured by ELISA in the serum of unselected patients fulfilling clinical and histo/immunopathological BP criteria at baseline (n = 71) and at time of relapse (n = 24). At baseline, anti-type VII collagen AAbs were detected in 2 out of 24 patients with BP presenting with mucosal involvement, but not in patients without mucosal lesions (n = 47). At the time of relapse, 10 out of 24 BP patients either displayed a significant induction or increase of concentrations of anti-type VII collagen AAbs (P < 0.01), independently of mucosal involvement. Those 10 relapsing BP patients were also characterized by a sustained high concentration of anti-BP180 AAb, whereas the serum anti-BP230 AAb concentrations did not vary in BP patients with relapse according to the presence of anti-type VII collagen AAbs. Thus, our study showed that anti-type VII collagen along with anti-BP180 AAbs detection stratified BP patients at time of relapse, illustrating a still dysregulated immune response that could reflect a potential epitope spreading mechanism in those BP patients.

Fecal calprotectin (FC) correlates with clinical and endoscopic activity in ulcerative colitis (UC), and it is a good predictor of relapse. However, its use in clinical practice is constrained by the need for the patient to deliver stool samples, and for their handling and processing in the laboratory. The availability of hand held devices might spread the use of FC in clinical practice. To evaluate the usefulness of a rapid semi-quantitative test of FC in predicting relapse in patients with UC in remission. Prospective, multicenter study that included UC patients in clinical remission for ≥6 months on maintenance treatment with mesalamine. Patients were evaluated clinically and semi-quantitative FC was measured using a monoclonal immunochromatography rapid test at baseline and every three months until relapse or 12 months of follow-up. One hundred and ninety-one patients had at least one determination of FC. At the end of follow-up, 33 patients (17%) experienced clinical relapse. Endoscopic activity at baseline (p = .043) and having had at least one FC > 60 μg/g during the study period (p = .03) were associated with a higher risk of relapse during follow-up. We obtained a total of 636 semi-quantitative FC determinations matched with a three-month follow-up clinical assessment. Having undetectable FC was inversely associated with early relapse (within three months), with a negative predictive value of 98.6% and a sensitivity of 93.9%. Serial, rapid semi-quantitative measurement of FC may be a useful, easy and cheap monitoring tool for patients with UC in remission.

The purpose of this study was to evaluate the predictive capacity of the European LeukemiaNet (ELN) classification of genetic risk in patients with acute myeloid leukaemia (AML) undergoing allogeneic stem cell transplantation (alloSCT). We retrospectively analysed 274 patients transplanted at our centre between 2004 and 2014. The ELN grouping is comparable to the Southwest Oncology Group/Eastern Cooperative Oncology Group (SWOG/ECOG) stratification in predicting the outcome after alloSCT [overall P = 0.0064 for disease-free survival (DFS), overall P = 0.003 for relapse]. Patients with an intermediate-1 profile have a significantly elevated 5-yr relapse incidence as compared to favourable risk patients, that is 40% vs. 15%, [hazard ratio (HR) 2.58, P = 0.048]. An intermediate-1 risk profile is an independent predictor for relapse as determined by multivariate Cox regression analysis (HR 3.05, P = 0.023). In intermediate-1 patients, the presence of an FLT3 internal tandem duplication (FLT3-ITD) is associated with a significantly increased relapse incidence (P = 0.0323), and a lower DFS (P = 0.0465). FLT3-ITD is an independent predictor for overall survival, DFS and relapse incidence in the intermediate-1 subgroup. The ELN stratification of genetic risk predicts the outcome of patients with AML undergoing alloSCT. Patients with an intermediate-1 profile have a high risk for treatment failure due to relapse, which prompts the development of alternative treatment strategies. © 2016 John Wiley & Sons A/S.

This study investigated the relationship between craving in abstinent alcohol-dependent patients measured by the Obsessive Compulsive Craving Scale (OCDS) (Anton et al., 1995) and relapse during and after completion of an intensive outpatient treatment programme. In a prospective study, participants were interviewed at entry to, and end of, an outpatient treatment programme, and 12 months after the end of the programme. To measuring craving the OCDS total score by Anton et al. (1995) and the three-factor model by Kranzler et al. (1999) were used. OCDS was administered at the beginning of treatment (when all patients were abstinent), and at the end of treatment in those who were abstinent and had completed the programme. Of 103 alcohol-dependent patients, 74 completed the treatment programme and at follow-up after 12 months 97% of these patients were personally re-interviewed. Thirty-two patients (31%) relapsed during the treatment phase. They had significantly higher craving measured by the total OCDS score and a significantly higher score on the subscales 'obsessions' and 'drinking control and consequences' compared to abstinent patients. Of the 74 patients who completed the programme 16% had a major relapse in the next 12 months. Major relapse was predicted by the total OCDS score and the subscale 'obsessions'. OCDS total score predicts relapse in outpatient treatment. Treatment and aftercare of patients with high craving should be intensified. In our study design, the subscales of the three-factor model by Kranzler et al. (1999) provided only little information gain compared to the OCDS total score.

For pediatric patients with acute lymphoblastic leukemia (ALL), relapse is an important cause of treatment failure after unrelated cord blood transplant (UCBT). Compared with other donor sources, relapse is similar or even reduced after UCBT despite less graft-versus-host disease (GVHD). We performed a retrospective analysis to identify risk factors associated with the 5-year cumulative incidence of relapse after UCBT. In this retrospective, registry-based study, we examined the outcomes of 640 children (<18 years) with ALL in first complete remission (CR1; n = 257, 40%) or second complete remission (CR2; n = 383, 60%) who received myeloablative conditioning followed by a single-unit UCBT from 2000 to 2012. Most received antithymocyte globulin (88%) or total body irradiation (TBI; 69%), and cord blood grafts were primarily mismatched at 1 (50%) or 2 + (34%) HLA loci. Considering patients in CR1, the rates of 5-year overall survival (OS), leukemia-free survival (LFS), and relapse were 59%, 52%, and 23%, respectively. In multivariate analysis (MVA), acute GVHD (grades II to IV) and TBI protected against relapse. In patients in CR2, rates of 5-year OS, LFS, and the cumulative incidence of relapse were 46%, 44%, and 28%, respectively. In MVA, longer duration from diagnosis to UCBT (≥30 months) and TBI were associated with decreased relapse risk. Importantly, receiving a fully HLA matched graft was a strong risk factor for increased relapse in MVA. An exploratory analysis of all 640 patients supported the important association between the presence of acute GVHD and less relapse but also demonstrated an increased risk of nonrelapse mortality. In conclusion, the impact of GVHD as a graft-versus-leukemia marker is evident in pediatric ALL after UCBT. Strategies that promote graft-versus-leukemia while harnessing GVHD should be further investigated. Copyright © 2017 The American Society for Blood and Marrow Transplantation.

We investigated patient and disease characteristics predictive of relapse of MDD during a 52-week placebo controlled trial of selegiline transdermal system (STS) to identify patient characteristics relevant for STS treatment. After 10 weeks of open-label stabilization with STS, 322 remitted patients with MDD were randomized to 52-weeks of double-blind treatment with STS (6 mg/24h) or placebo (PLB). Relapse was defined as Hamilton Depression Rating Scale (HAMD-17) score of ≥ 14 and a CGI-S score of ≥ 3 with at least 2-point increase from the beginning of the double blind phase on 2 consecutive visits. Cox's proportional hazards regression was used to examine the effect of potential predictors (age, sex, age at onset of first MDD, early response pattern, number of previous antidepressant trials, severity of index episode, number of previous episodes, melancholic features, atypical features and anxious feature) on outcome. Exploratory analyses examined additional clinical variables (medical history, other psychiatric history, and individual items of HAM-D 28) on relapse. For all predictor variables analyzed, treatment Hazard Ratio (HR=0.48~0.54) was significantly in favor of STS (i.e., lower relapse risk than PLB). Age of onset was significantly predictive of relapse. Type, duration, and severity of depressive episodes, previous antidepressant trials, or demographic variables did not predict relapse. In additional exploratory analysis, eating disorder history and suicidal ideation were significant predictors of relapse after controlling for the effect of treatment in individual predictor analysis. While age of onset, eating disorder history and suicidal ideation were significant predictors, the majority of clinical and demographic variables were not predictive of relapse. Given the post-hoc nature of analysis, the findings need confirmation from a prospective study. It appears that selegiline transdermal system was broadly effective in preventing relapse across different subtypes and symptoms clusters of MDD. © 2013 Published by Elsevier B.V.

Sixty patients (greater than 16 yrs old) suffering primary or relapse genital herpes simplex viruses (HSV) and relapse labial HSV were appointed for this study. Three or more relapses were experienced per year. Patients (under treatment) were divided into two groups (distribution areas), corresponding to either labial herpes or genital herpes. These groups were sub-divided into 3 groups. The total number of labial or facial HSV patients was 36 (10 in group 1, 12 in group 2, 14 in group 3) and 24 for genital, buttocks, or 'area pudenda' HSV patients (6 in group 1, 8 in group 2, 10 in group 3). The design was a randomized, double- blind study. The setting was hospital and outpatient. The patients diagnosed as having the HVS disease were sent to the dermatology department and were assigned to a group at random. Treatment was begun as follows: During the treatment signs and symptoms were assessed and after the treatment, the relapses were also assessed (biochemical and hematological tests before and after the treatment) and the diagnosis of the HSV type I and II. The statistical evaluation of the results was performed and carried out with the SPSS and BMDP program. The relapses of the herpes infection in the lips and the face were significantly reduced (p less than 0.026) in patients treated with laser He-Ne and laser He-Ne plus Acyclovir. The interim between the relapses also increased significantly (p less than 0.005) in relation with the group treated with Acyclovir. The duration of the herpetic eruptions was clearly reduced in all locations in patients treated with laser He-Ne plus Acyclovir. No differences were noted between patients treated with laser He-Ne only or Acyclovir only. Therefore it is probable that therapeutic synergism took place. In relation with this, laser He-Ne shows the same therapeutic efficacy as Acyclovir taken orally. The association of Acyclovir and laser Ne-Ne could be an alternative method for the treatment of HSV in the face. The number of relapses of the herpes infection in the genital, buttocks or 'area pudenda' and the interim between the relapses were not substantially modified with the treatment of laser He-Ne or laser Ne-Ne plus Acyclovir. Although a little difference exists in comparison with the patients treated with Acyclovir alone, a survey or an increased number of patients should be necessary.

Background: To evaluate the effectiveness of a relapse prevention cognitive-behavioral model, based on Marlatt treatment approach, in Opioid-dependent patients participating in the Methadone Maintenance Treatment (MMT) in Iran. Methods: The study consisted of 92 individuals treated with methadone in Iranian National Center of Addiction Studies (INCAS). Participants were randomized into two groups: educational intervention group (N=46) and control group (N=46). The intervention was comprised of 10 weekly 90 minute sessions, done during a period of 2.5 months based on the most high risk situations determined using Inventory Drug Taking Situation instrument. Relapse was defined as not showing up for MMT, drug use for at least 5 continuous days, and a positive urinary morphine test. Results: While, only 36.4% of the intervention group relapsed into drug use, 63.6% of the control group relapsed. The result of the logistic regressions showed that the odd ratio of the variable of intervention program for the entire follow up period was 0.43 (P<0.01). Further, the odd ratio of this variable in one month, three months, and 195 days after the therapy were 0.48 (P<.03), 0.31 (P<.02), and 0.13 (P<.02) respectively that revealed that on average, the probability of relapse among individuals in the intervention group was lower than patients in control group Conclusion: Relapse prevention model based on Marlatt treatment approach has an effective role in decreasing relapse rate. This model can be introduced as a complementary therapy in patients treated with methadone maintenance. PMID:26056645

With this symposium, we focused on the relapse of tuberculosis in Japan. Out of 19,893 tuberculosis patients registered in 2007 in Japan, 7.48% were classified as relapse cases. Relapse cases have the risk of acquired drug resistance. But we have few analyses of the proportion of relapse tuberculosis cases with standard short course regimens for six months, factors contributing to tuberculosis relapse and the proportion of drug resistance among relapse TB cases in Japan. Therefore we analyzed the relapse tuberculosis cases in two rural areas and three urban areas. We also analyzed the proportion of drug resistance among relapse cases with the data of drug susceptibility survey of Ryoken. 1. Research of relapse tuberculosis cases: Makoto TOYOTA (Kochi City Public Health Center). To clarify the relapse rate and factors contributing to tuberculosis relapse, we investigated the relapse tuberculosis cases in the municipality where the proportion of elderly tuberculosis patients was high. Out of 902 tuberculosis patients registered in Kochi City Public Health Center during 10 years, 20 pulmonary tuberculosis patients were confirmed relapse cases with initial registered records. Pretreatment cavitations, sputum culture positivity at 2 months, medical miss-management (e.g. number of doses, duration of therapy) and poor adherence were considered to be factors contributing to tuberculosis relapse. Out of 20 relapse cases, 12 cases were detected with symptoms, while only 3 cases were detected by examination in law. 2. A clinical study on relapse cases of pulmonary tuberculosis: Shuichi TAKIKAWA (National Hospital Organization Nishibeppu National Hospital). The relapse of pulmonary tuberculosis was investigated. In the cases with a treatment history before short course chemotherapy, drug resistance rate was high, and thus it needs to be cautious of drug resistance at the time of the retreatment. In the cases with a treatment history of short course chemotherapy, relapse cases were recognized more significantly in male cases aged 70's. In the cases that deviated from the standard treatment and that became impossible to use rifampicin, it should be careful to emergence of isoniazid resistance. 3. The current status of the recurrence tuberculosis cases in Tokyo: Michiko NAGAMINE (Specific Disease Control Section, Tokyo Metropolitan Government Bureau of Social Welfare and Public Health). As for the background of the patient whose disease has relapsed, unstable elements are observed. After any symptom, more patients are diagnosed as a relapse case rather than finding by a medical check up. And more than half are related to homeless or life without fixed address. Their status of insurance is the livelihood protection, no insurance or the national health insurance. By RFLP analysis in Shinjuku city, some clusters have recurrent cases, one of clusters has both a relapse and exogenous reinfection. This is able to elucidate an infectious state. Like this, the analysis of each cluster can help effective countermeasures. 4. Recurrence of tuberculosis in the City of Yokohama between 2004 and 2008: Michihiko YOSHIDA (Shinagawa Public Health Center), Takahiro TOYOZAWA (Yokohama Public Health Center). To identify the TB recurrence rate, we studied a cohort of 40 cases (treatment completion 36 cases, interruption 4 cases) of whom had a previous history of TB treatment including isoniazid and rifampicin. The time for relapse was 7.9 +/- 8.6 years and the overall relapse rate was 0.6% (0.47-0.7%). Our study suggested the relapse was almost equal to the low incident countries but the long-term follow-up and surveillance data should be carefully evaluated. 5. Comparison of the retreatment cases of pulmonary tuberculosis: Yuka SASAKI (National Hospital Organization Chiba-East National Hospital). To investigate the factors of the retreatment of pulmonary tuberculosis, 134 retreatment cases were studied. The factors leading to retreatment were cavitary and large lesions in chest X-p, sputum smear positive and heavy alcohol-drinkers. The factors leading to defaulting of the treatment were lack in understanding of the treatment and their economic problems. Reexamination of the treatment and support of the patients are important to prevent the retreatment of the pulmonary tuberculosis. 6. Proportion of drug resistance among relapse tuberculosis cases, summary of Ryoken studies 1977-2002: Takashi YOSHIYAMA (Fukujuji Hospital). We have no historical analysis of the proportion of drug resistance among relapse TB cases. Therefore we would like to analyze the proportion of drug resistance among relapse cases in Japan. Re-analysis of the data of drug susceptibility survey of Ryoken from 1977 to 2002. The proportion of relapse cases among Ryoken has decreased in 1982-1987 and that proportion was 10% in 2002. The average age of relapse cases was 5 years older than the new cases and it was 66 years in 2002. The proportion of drug resistance among relapse cases has decreased form 39% (in 1977) to 16% (in 2002) for isoniazid, was stable and around 10% for rifampicin with 7.5% in 2002. The risk factors for drug resistance were younger age, foreigners and part time job. The proportion of drug resistance was higher among cases that were failure with previous treatment, then default with previous treatment and lower among cases with cure/completion at the previous treatment but this tendency was without significance.

To provide new insights into the role of markers of response to interferon-β therapy in multiple sclerosis (MS) in a multicenter setting, focusing on the relevance of MRI lesions in combination with clinical variables. A large multicenter clinical dataset was collected within the Magnetic Resonance Imaging in MS (MAGNIMS) network. This included a large cohort of patients with relapsing-remitting MS on interferon-β treatment, MRI and clinical assessments during the first year of treatment, and clinical follow-up of at least 2 additional years. Heterogeneity among centers was assessed before pooling the data. The association of 1-year MRI or clinical relapses with the risk of treatment failure (defined as Expanded Disability Status Scale [EDSS] worsening or treatment switch for inefficacy) and of EDSS worsening alone was evaluated using multivariate Cox models. A pooled dataset of 1,280 patients with relapsing-remitting MS from 9 MAGNIMS centers was analyzed. The risk of failure had a relevant increase with 1 relapse (hazard ratio [HR] 1.84, 95% confidence interval [CI] 1.39-2.44, p < 0.001) and ≥3 new T2 lesions (HR 1.55, 95% CI 0.92-2.60, p = 0.09). In patients without relapses and less than 3 new T2 lesions, the 3-year risk of failure and EDSS worsening were 17% and 15%; in patients with 1 relapse or ≥3 new T2 lesions, the risks were 27% and 22%; in patients with both conditions or more than 1 relapse, the risks were 48% (p < 0.001) and 29% (p < 0.001). Substantial MRI activity, particularly if in combination with clinical relapses, during the first year of treatment with interferon-β indicates significant risk of treatment failure and EDSS worsening in the short term. © 2016 American Academy of Neurology.

Sleeping sickness caused by Trypanosoma brucei (T.b.) gambiense constitutes a serious health problem in sub-Sahara Africa. In some foci, alarmingly high relapse rates were observed in patients treated with melarsoprol, which used to be the first line treatment for patients in the neurological disease stage. Particularly problematic was the situation in Mbuji-Mayi, East Kasai Province in the Democratic Republic of the Congo with a 57% relapse rate compared to a 5% relapse rate in Masi-Manimba, Bandundu Province. The present study aimed at investigating the mechanisms underlying the high relapse rate in Mbuji-Mayi using an extended collection of recently isolated T.b. gambiense strains from Mbuji-Mayi and from Masi-Manimba. Forty five T.b. gambiense strains were used. Forty one were isolated from patients that were cured or relapsed after melarsoprol treatment in Mbuji-Mayi. In vivo drug sensitivity tests provide evidence of reduced melarsoprol sensitivity in these strains. This reduced melarsoprol sensitivity was not attributable to mutations in TbAT1. However, in all these strains, irrespective of the patient treatment outcome, the two aquaglyceroporin (AQP) 2 and 3 genes are replaced by chimeric AQP2/3 genes that may be associated with resistance to pentamidine and melarsoprol. The 4 T.b. gambiense strains isolated in Masi-Manimba contain both wild-type AQP2 and a different chimeric AQP2/3. These findings suggest that the reduced in vivo melarsoprol sensitivity of the Mbuji-Mayi strains and the high relapse rates in that sleeping sickness focus are caused by mutations in the AQP2/AQP3 locus and not by mutations in TbAT1. We conclude that mutations in the TbAQP2/3 locus of the local T.b. gambiense strains may explain the high melarsoprol relapse rates in the Mbuji-Mayi focus but other factors must also be involved in the treatment outcome of individual patients.

To estimate real-world treatment patterns, safety, and relapse outcomes of subcutaneous (sc) interferon (IFN) β-1a (Rebif) vs dimethyl fumarate (DMF; Tecfidera), to treat relapsing-remitting multiple sclerosis (RRMS). A US retrospective chart review of 450 randomly selected adults newly diagnosed with RRMS who received sc IFN β-1a (n = 143) or DMF (n = 307) was conducted. Patients were either (a) treatment-naïve, initiating first-line treatment with sc IFN β-1a or DMF, or (b) previously treated, switching to sc IFN β-1a or DMF. Two years' follow-up data were captured. Patient characteristics, persistence, and adverse events between treatment groups were compared using t-tests or Chi-square tests. Kaplan-Meier curves with log-rank tests and Cox proportional hazards models were used to compare time to, and risk of non-persistence. Annualized Relapse Rates (ARR) were calculated using a robust variance Poisson model adjusting for covariates. Propensity scores were used to address possible selection bias. One hundred and twelve patients became non-persistent, most commonly due to an adverse event (n = 37). No difference was observed in time to overall non-persistence between sc IFN β-1a and DMF patients. Among treatment-naïve patients, those receiving DMF had 2.4-times the risk (HR = 2.439, 95% CI = 1.007-5.917, p = .0483) of experiencing a discontinuation than patients receiving sc IFN β-1a. Non-persistent patients receiving DMF had 2.3-times the risk (HR = 2.311, 95% CI = 1.350-3.958, p = .0023) of experiencing an adverse event at a given time point than patients prescribed sc IFN β-1a. No differences in relapse risk or ARR between sc IFN β-1a- and DMF-treated patients were observed. sc IFN β-1a-treated patients had comparable persistence and relapse outcomes, and better safety outcomes vs DMF-treated patients across 2 years.

Negative affective states and alcohol-related stimuli increase risk of relapse in alcohol dependence. In research and in clinical practice, craving is often used as another important indicator of relapse, but this lacks a firm empirical foundation. The goal of the present study is to explore and compare determinants for relapse and craving, using Marlatt's (1996) taxonomy of high risk situations as a template. We conducted semi-structured interviews with 20 alcohol-dependent patients about their most recent relapse and craving episodes. Interview transcripts were carefully reviewed for their thematic content, and codes capturing the thematic content were formulated. In total, we formulated 42 relapse-related codes and 33 craving-related codes. Descriptions of craving episodes revealed that these episodes vary in frequency and intensity. The presence of alcohol-related stimuli (n = 11) and experiencing a negative emotional state (n = 11) were often occurring determinants of craving episodes. Both negative emotional states (n = 17) and testing personal control (n = 11) were viewed as important determinants of relapses. Craving was seldom mentioned as a determinant for relapse. Additionally, participants reported multiple determinants preceding a relapse, whereas craving episodes were preceded by only one determinant. Patient reports do not support the claim that craving by itself is an important proximal determinant for relapse. In addition, multiple determinants were present before a relapse. Therefore, future research should focus on a complexity of different determinants.

Multiple sclerosis (MS) is a chronic disease that affects mainly adults in the prime of their lives. However, few studies report the impact of high annual relapse rates on outcomes. The purpose of this study was to identify high relapse activity (HRA) in patients with MS, comparing differences in outcomes between patients with and without HRA. A retrospective longitudinal study was conducted using the MarketScan® Commercial Claims and Encounters and Medicare Supplemental Database. Patients had to have at least one ICD-9 for MS (340.XX) in 2009 and one in 2008, be older than 18 years, and have continuous enrolment in the years 2009-2010. HRA was defined as having ≥2 relapses in 2009. Multivariate analyses compared all-cause and MS-specific emergency room (ER) visits, hospitalizations, and all-cause costs, excluding disease modifying therapy (DMT) costs, in 2010 between patients with and without HRA, controlling for baseline characteristics. A subgroup analysis using treatment exposure was also performed. 19,219 patients were included: 5.3% (n=1,017) had ≥2 relapses in 2009. Patients with HRA were more likely to have all-cause and MS-specific resource utilization than patients without HRA. Mean total all-cause non DMT costs were $12,057 higher for the HRA group. In the subgroup analysis, HRA treatment-naïve patients were more likely to start treatment, and HRA treatment-experienced patients were more likely to discontinue or switch index DMT (P<0.01). Patients with ≥2 relapses annually have higher resource utilization and costs. The difference in cost was over twice as large in treatment-naïve patients versus treatment-experienced patients. HRA was also associated with an increased likelihood of starting DMT treatment (treatment-naïve patients), and switching or discontinuing DMT therapy (treatment-experienced patients).

The N-methyl-d-aspartate (NMDA) glutamate receptor antagonist ketamine may have rapid, albeit transient, antidepressant properties. This study in patients with treatment-resistant major depression (TRD) aimed to (1) replicate the acute efficacy of single-dose intravenous (i.v.) ketamine; (2) test the efficacy of the glutamate-modulating agent riluzole in preventing post-ketamine relapse ; and (3) examine whether pretreatment with lamotrigine would attenuate ketamine’s psychotomimetic effects and enhance its antidepressant activity. Twenty-six medication-free patients received open-label i.v. ketamine (0.5 mg/kg over 40 min). Two hours prior to infusion, patients were randomized to lamotrigine (300 mg) or placebo. Seventeen patients (65%) met response criterion (≥50% reduction from baseline on the Montgomery–Asberg Depression Rating Scale) 24 h following ketamine. Lamotrigine failed to attenuate the mild, transient side-effects associated with ketamine and did not enhance its antidepressant effects. Fourteen patients (54%) met response criterion 72 h following ketamine and proceeded to participate in a 32-d, randomized, double-blind, placebo-controlled, flexible-dose continuation trial of riluzole (100–200 mg/d). The main outcome measure was time-to-relapse. An interim analysis found no significant differences in time-to-relapse between riluzole and placebo groups [log-rank χ2 = 0.17, d.f. = 1, p = 0.68], with 80% of patients relapsing on riluzole vs. 50% on placebo. The trial was thus stopped for futility. This pilot study showed that a sub-anaesthetic dose of i.v. ketamine is well-tolerated in TRD, and may have rapid and sustained antidepressant properties. Riluzole did not prevent relapse in the first month following ketamine. Further investigation of relapse prevention strategies post-ketamine is necessary. PMID:19288975

Relapsed, histologically aggressive non-Hodgkin lymphoma (NHL) has a poor prognosis; relapsed patients who do not respond to second line therapy or are unfit for BMT have a worse prognosis. Angiogenesis is increased in aggressive NHL and could be targeted by selective cyclooxygenase-2 inhibition and metronomic chemotherapy. We assessed the toxicity of metronomic chemotherapy and the response and progression-free survival in patients with relapsed/refractory diffuse large B-cell lymphoma (DLBCL). We prospectively studied 41 patients with a diagnosis of relapsed and/or refractory DLBCL who may have received any number of preceding therapies (as long as one included an anthracycline) and were not candidates for bone marrow transplantation. They received oral cyclophosphamide (50 mg every day), oral methotrexate (2.5 mg 4 times/week) and high-dose oral celecoxib (400 mg twice daily) until there was disease progression or unacceptable toxicity. All 41 patients (median age, 56 years) were evaluable for toxicity and response, with a median follow up of 9.1 months (range, 4-35 months). At relapse, 51.2% had a high international prognostic index. The treatment protocol was well tolerated with no major toxicities. The most common toxicities were fatigue (61%), nausea (22%), neutropenia (19.5%), and anemia (22%). In 31.7% there was a partial response and 48.8% had stable disease. Progression-free survival was 12 months. The median response duration was 10 months. We conclude that metronomic chemotherapy can be used for patients with relapsed and or refractory DLBCL with reasonable outcome and acceptable toxicity. Standard approaches such as hematopoietic stem cell transplantation and chemo-immunotherapy combinations should be explored prior to a decision on metronomic chemotherapy.

Patients with multiply relapsed or refractory chronic lymphocytic leukemia (CLL) have a poor prognosis. Chimeric antigen receptor (CAR)–modified T cells targeting CD19 have the potential to improve on the low complete response rates with conventional therapies by inducing sustained remissions in patients with refractory B cell malignancies. We previously reported preliminary results on three patients with refractory CLL. We report the mature results from our initial trial using CAR-modified T cells to treat 14 patients with relapsed and refractory CLL. Autologous T cells transduced with a CD19-directed CAR (CTL019) lentiviral vector were infused into patients with relapsed/refractory CLL at doses of 0.14 × 108 to 11 × 108 CTL019 cells (median, 1.6 × 108 cells). Patients were monitored for toxicity, response, expansion, and persistence of circulating CTL019 T cells. The overall response rate in these heavily pretreated CLL patients was 8 of 14 (57%), with 4 complete remissions (CR) and 4 partial remissions (PR). The in vivo expansion of the CAR T cells correlated with clinical responses, and the CAR T cells persisted and remained functional beyond 4 years in the first two patients achieving CR. No patient in CR has relapsed. All responding patients developed B cell aplasia and experienced cytokine release syndrome, coincident with T cell proliferation. Minimal residual disease was not detectable in patients who achieved CR, suggesting that disease eradication may be possible in some patients with advanced CLL. PMID:26333935

Mantle cell lymphoma (MCL) is a heterogeneous disease with high relapse rates. Limited data guide the use of surveillance imaging following treatment. We constructed a retrospective cohort from two academic institutions of patients with MCL who completed first-line therapy and underwent follow-up for relapse, analyzing the effect of surveillance imaging on survival. Of 217 patients, 102 had documented relapse, with 38 (37%) diagnosed by surveillance imaging and 64 (63%) by other methods. Relapse diagnosis by surveillance imaging had no significant advantage in overall survival from diagnosis date (hazard ratio [HR] = 0.80, p = .39) or relapse date (HR = 0.72, p = .22). Of 801 surveillance images, PET/CT had a positive predictive value (PPV) of 24% and number needed-to-scan/treat (NNT) of 51 to detect one relapse, and CT had a PPV of 49% and NNT of 24. For MCL after first-line therapy, relapse detection by surveillance imaging was not associated with improved survival and lacks clinical benefit.

To determine factors associated with smoking relapse in men who survived from their first stroke. Data were collected through face to face interviews with stroke patients in the hospital, and then repeated every three months via telephone over the period from 2010 to 2014. Kaplan-Meier method and competing risk model were adopted to estimate and predict smoking relapse rates. The Kaplan-Meier method estimated a higher relapse rate than the competing risk model. The four-year relapse rate was 43.1% after adjustment of competing risk. Exposure to environmental tobacco smoking outside of home and workplace (such as bars and restaurants) ( P =0.01), single ( P <0.01), and prior history of smoking at least 20 cigarettes per day ( P =0.02) were significant predictors of smoking relapse. When competing risks exist, competing risks model should be used in data analyses. Smoking interventions should give priorities to those without a spouse and those with a heavy smoking history. Smoking ban in public settings can reduce smoking relapse in stroke patients.

A simplified prognostic score is presented based on the multivariate analysis of 138 refractory/relapsed acute myeloid leukaemia (AML) patients (median age 55 years, range: 19-70) receiving a combination of intensive chemotherapy+Gemtuzumab as salvage regimen. Overall, 2-year event-free survival (EFS) and overall survival (OS) were 29±4% and 36±4%, respectively. Disease status (relapse <12 months, including refractory patients), FLT3-ITD-positive status and high-risk cytogenetics were the three strongest independent adverse prognostic factors for OS and EFS in this series. We then defined three subgroups with striking different outcomes at 2 years: no adverse factor (favourable, N=36): OS 58%, EFS 45%; one adverse factor (intermediate, N=54): OS 37%, EFS 31%; two or three adverse factors (poor, N=43): OS 12%, EFS 12% (P<10(-4), P=0.001). This new simplified Leukemia Prognostic Scoring System was then validated on an independent cohort of 111 refractory/relapsed AML patients. This new simplified prognostic score, using three clinical and biological parameters routinely applied, allow to discriminate around two third of the patients who should benefit from a salvage intensive regimen in the setting of refractory/relapsed AML patients. The other one third of the patients should receive investigational therapy.

Radiation therapy in adenoid-cystic carcinoma

Between 1949-1977, 74 patients with adenoid-cystic carcinoma of various head and neck sites were treated by radiation therapy at Memorial Sloan-Kettering Cancer Center. Radiation therapy alone was employed in 49 patients for recurrent, unresectable disease, and in 25 patients it was given as an adjunct to surgical resection. Among the 49 patients treated with radiation therapy alone, tumor regression was seen in 47 (96%). However, 44 of the 47 (93.5%) subsequently relapsed locally. Relapse occurred within 18 months in one-half of the patients and within 5 years in all of them. Of the 25 patients who received adjunctive radiation therapymore » about one-half relapsed locally within five years. There were 9 patients in this group, however, whose field size exceeded 8x8 cm and the dose of radiation also exceeded 4500 rad: 88% of these patients remained relapse-free at 5 years, compared with only 22% of the other 16 whose dose, or field size, or both, were inadequate by comparison. These data suggest that when irradiation is employed for advanced, inoperable adenoid-cystic carcinoma, it offers useful palliation but is rarely, if ever, curative. Postoperative irradiation, on the other hand, might improve the local control and the survival in patients with operable adenoid-cystic carcinoma who are at high risk for relapse, but only if the field size and the dose are adequate.« less

Hand eczema influences the quality of life. Management strategies include the use of moisturizers. In the present study the time to relapse of eczema during treatment with a barrier-strengthening moisturizer (5% urea) was compared with no treatment (no medical or non-medicated preparations) in 53 randomized patients with successfully treated hand eczema. The median time to relapse was 20 days in the moisturizer group compared with 2 days in the no treatment group (p = 0.04). Eczema relapsed in 90% of the patients within 26 weeks. No difference in severity was noted between the groups at relapse. Dermatology Life Quality Index (DLQI) increased significantly in both groups; from 4.7 to 7.1 in the moisturizer group and from 4.1 to 7.8 in the no treatment group (p < 0.01) at the time of relapse. Hence, the application of moisturizers seems to prolong the disease-free interval in patients with controlled hand eczema. Whether the data is applic-able to moisturizers without barrier-strengthening properties remains to be elucidated.

Objective: To study rituximab in pediatric neuromyelitis optica (NMO)/NMO spectrum disorders (NMOSD) and the relationship between rituximab, B cell repopulation, and relapses in order to improve rituximab monitoring and redosing. Methods: Multicenter retrospective study of 16 children with NMO/NMOSD receiving ≥2 rituximab courses. According to CD19 counts, events during rituximab were categorized as “repopulation,” “depletion,” or “depletion failure” relapses (repopulation threshold CD19 ≥10 × 106 cells/L). Results: The 16 patients (14 girls; mean age 9.6 years, range 1.8–15.3) had a mean of 6.1 events (range 1–11) during a mean follow-up of 6.1 years (range 1.6–13.6) and received a total of 76 rituximab courses (mean 4.7, range 2–9) in 42.6-year cohort treatment. Before rituximab, 62.5% had received azathioprine, mycophenolate mofetil, or cyclophosphamide. Mean time from rituximab to last documented B cell depletion and first repopulation was 4.5 and 6.8 months, respectively, with large interpatient variability. Earliest repopulations occurred with the lowest doses. Significant reduction between pre- and post-rituximab annualized relapse rate (ARR) was observed (p = 0.003). During rituximab, 6 patients were relapse-free, although 21 relapses occurred in 10 patients, including 13 “repopulation,” 3 “depletion,” and 4 “depletion failure” relapses. Of the 13 “repopulation” relapses, 4 had CD19 10–50 × 106 cells/L, 10 had inadequate monitoring (≤1 CD19 in the 4 months before relapses), and 5 had delayed redosing after repopulation detection. Conclusion: Rituximab is effective in relapse prevention, but B cell repopulation creates a risk of relapse. Redosing before B cell repopulation could reduce the relapse risk further. Classification of evidence: This study provides Class IV evidence that rituximab significantly reduces ARR in pediatric NMO/NMOSD. This study also demonstrates a relationship between B cell repopulation and relapses. PMID:26819962

Recurrences of diffuse large B-cell lymphomas (DLBCL) result in significant morbidity and mortality, but their underlying genetic and biological mechanisms are unclear. Clonal relationship in DLBCL relapses so far is mostly addressed by the investigation of immunoglobulin (IG) rearrangements, therefore, lacking deeper insights into genome-wide lymphoma evolution. We studied mutations and copy number aberrations in 20 paired relapsing and 20 non-relapsing DLBCL cases aiming to test the clonal relationship between primaries and relapses to track tumors' genetic evolution and to investigate the genetic background of DLBCL recurrence. Three clonally unrelated DLBCL relapses were identified (15%). Also, two distinct patterns of genetic evolution in clonally related relapses were detected as follows: (1) early-divergent/branching evolution from a common progenitor in 6 patients (30%), and (2) late-divergent/linear progression of relapses in 11 patients (65%). Analysis of recurrent genetic events identified potential early drivers of lymphomagenesis (KMT2D, MYD88, CD79B and PIM1). The most frequent relapse-specific events were additional mutations in KMT2D and alterations of MEF2B. SOCS1 mutations were exclusive to non-relapsing DLBCL, whereas primaries of relapsing DLBCL more commonly displayed gains of 10p15.3-p12.1 containing the potential oncogenes PRKCQ, GATA3, MLLT10 and ABI1. Altogether, our study expands the knowledge on clonal relationship, genetic evolution and mutational basis of DLBCL relapses.

Purpose: To evaluate the incidence of nodal relapses from carcinomas of the salivary glands among patients with clinically negative necks in an attempt to determine the potential utility of elective neck irradiation (ENI). Methods and Materials: Between 1960 and 2004, 251 patients with clinically N0 carcinomas of the salivary glands were treated with surgery and postoperative radiation therapy. None of the patients had undergone previous neck dissection. Histology was: adenoid cystic (84 patients), mucoepidermoid (60 patients), adenocarcinoma (58 patients), acinic cell (21 patients), undifferentiated (11 patients), carcinoma ex pleomorphic adenoma (7 patients), squamous cell (7 patients), and salivary duct carcinomamore » (3 patients); 131 patients (52%) had ENI. Median follow-up was 62 months (range, 3-267 months). Results: The 5- and 10-year actuarial estimates of nodal relapse were 11% and 13%, respectively. The 10-year actuarial rates of nodal failure were 7%, 5%, 12%, and 16%, for patients with T1, T2, T3, and T4 disease, respectively (p = 0.11). The use of ENI reduced the 10-year nodal failure rate from 26% to 0% (p = 0.0001). The highest crude rates of nodal relapse among those treated without ENI were found in patients with squamous cell carcinoma (67%), undifferentiated carcinoma (50%), adenocarcinoma (34%), and mucoepidermoid carcinoma (29%). There were no nodal failures observed among patients with adenoid cystic or acinic cell histology. Conclusion: ENI effectively prevents nodal relapses and should be used for select patients at high risk for regional failure.« less

Renal lymphoma is an uncommon renal tumor in children. Unlike renal lymphomas presenting as bilateral disease and renal failure, we report a boy who presented with unilateral renal involvement. After initial nephrectomy, he achieved remission with multiagent chemotherapy but relapsed systemically within 3 months. He was initiated on salvage chemotherapy with autologous bone marrow transplant. Even though the initial manifestation was localized lymphoma eventually, it turned out to be a systemic disease. He succumbed to disease at 14 months from diagnosis.

Studies addressing relapse rates conflate relapse into chronic migraine (CM) and medication overuse (MO), and the consequent need to repeat withdrawal. We aim to identify 12-months predictors of relapse into CM (based on headaches frequency) separately from occurrence of another structured withdrawal. Hospitalized patients with CM-MO under withdrawal were enrolled. Candidate predictors included demographic, disability, quality of life, depression scores, general self-efficacy, social support, headaches frequency and intensity, class of overused medications, history of withdrawal treatment in the three years prior to enrollment, attendance to emergency room (ER) between enrollment and follow-up, nonattendance to outpatient neurological examinations. Logistic regressions was used to address the significant predictors for the two outcomes. Complete data were available for 177 patients: 60 (33.9%) relapsed into CM, 38 (21.5%) underwent another withdrawal treatment. Recent history of withdrawal treatments, ER admission after discharge and high baseline BDI-II scores were significant predictors in both models. In addition to this, high baseline headache frequency predicted relapse into another withdrawal treatment. Predictors or relapse into CM and of occurrence of another withdrawal by 12-months are somehow similar. It is important to assess presence of recent previous withdrawal treatments and to plan regular follow-up afterwards, in particular for patients with high headache frequency and relevant mood disturbances: in this way, it will be more likely that situations requiring further structured withdrawal treatments can be identified before patients have to refer to ER. © 2016 American Headache Society.

Allogeneic SCT for myeloma may be curative for young patients, but its role remains controversial because of a reported high TRM in some series. Since 1991, we have performed 25 allografts for myeloma using fully matched sibling donors. Of the 18 evaluable patients, 13 achieved CR at a median time of 2.5 months post-transplant. The five patients who were not in CR when assessed at 3 months received a short course of alpha-interferon and four subsequently achieved CR with this approach at a median of 82 days. One patient who failed to respond to IFN went on to achieve CR after four doses of DLI therapy, thus giving an overall CR rate of 72%. Seven patients have relapsed at a median of 4.7 years post-transplant (range 1.38-7.7 years) including two patients who had received IFN therapy. In five of these cases, relapse has been as a localised area of bone disease or isolated plasmacytoma with no evidence of marrow involvement by trephine biopsy or molecular analysis. All patients with localised relapse were treated with local radiotherapy +/-DLI and four are currently disease free despite two patients having had further treatment for a second localised lesion. Six patients died of TRM (24%) and the OS at 8 years is currently 69% with an EFS of 26%. These results suggest that allogeneic SCT for myeloma can be carried out with an acceptable TRM and a high CR rate. However, late relapses as localised disease may be a frequent finding and may represent foci of myeloma not eradicated by the conditioning. The use of pretransplant MRI scanning and top-up radiotherapy to involved areas may be useful in preventing this type of relapse.

To investigate the feasibility of contralateral lower neck sparing intensity modulation radiated therapy (IMRT) for nasopharyngeal carcinoma patients (NPC) with unilateral cervical lymph node metastasis. Retrospective review of 546 patients with unilateral cervical lymph node metastasis treated between November 2009 and February 2012 at one institution. All patients were staged using magnetic resonance imaging and received radical IMRT. Patients were classified into two groups: the inferior border of the negative neck irradiation field only covered Levels III to Va in Group 1; the inferior border covered entire neck down to Levels IV to Vb in Group 2. Median follow-up was 49.9months (range, 1.3-69.2months). Four-year overall survival (OS:89.3% vs. 88.9%, P=0.91), disease-free survival (DFS:81.7% vs. 81.0%, P=0.91), distant metastasis-free survival (DMFS:88.2% vs. 87.9%, P=0.95), local relapse-free survival (LRFS:96.7% vs. 94.7%, P=0.70) and nodal relapse-free survival (NRFS: 96.1% vs. 95.9%, P=0.94) were not significantly different between Group 1 and Group 2. Twenty-two patients developed cervical lymph node relapse; of whom 20/22 (91.0%) developed unilateral relapse within pretreatment positive neck. Only one patient developed out-of-field relapse, though this patient also relapsed within the neck irradiation field (Level II). No clinicopathological feature tested had significant prognostic value for NRFS in multivariate analysis. In the IMRT and MRI era, contralateral lower neck sparing IMRT seems to be feasible for NPC patients with unilateral cervical lymph node metastasis. Copyright © 2017. Published by Elsevier Ltd.

Electroconvulsive Therapy in the Treatment of Mood Disorders: One-Year Follow-up.

Electroconvulsive therapy (ECT) is known to be an effective option in the treatment of mood disorders, especially resistant depression. However, the remission achieved by ECT was reported to be not long lasting enough. The aim of the present study was to investigate the relapse/recurrence rates and associated risk factors during the first year after ECT in patients diagnosed with mood disorders. In a naturalistic observation, patients diagnosed with unipolar depressive disorder or a depressive episode of bipolar disorder and who had achieved remission by ECT were followed up for at least one year. The patients were evaluated with structured interviews during the follow-up period. The relapse/recurrence rates were the primary outcome measurements, while hospitalization and suicide attempts were the secondary outcome measurements. The remitted and non-remitted patients were compared regarding the clinical features, ECT, and pharmacological variables. Fifty of 62 patients who had achieved remission with ECT completed the one year follow-up period. Thirty-three patients (66%) had relapse/recurrence, while 17 (34%) patients remained in remission. The relapse rates were similar in patients with unipolar depression and bipolar disorders. The mean number of ECT sessions was higher in relapsed patients with bipolar disorders. Multiple episodes were more frequent in non-remitted patients with unipolar depression. Comorbid psychiatric diagnosis was higher in non-remitted patients with unipolar and bipolar disorders. The relapse/recurrence rate was found to be fairly high in the first year of follow-up in patients who had achieved remission with ECT. ECT decisions should be made carefully in patients with comorbid psychiatric diagnosis and multiple episodes as these are more risky. The ECT application procedure and successive maintenance treatment (maintenance ECT, pharmacotherapy, and psychotherapy) should be planned to sustain the remission for patients with mood disorders in long-term follow-up.

In the present study, we explored the risk factors for relapse after discontinuation of biologic disease-modifying antirheumatic drug (bDMARD) therapy in patients with rheumatoid arthritis (RA) whose ultrasound power Doppler (PD) synovitis activity and clinical disease activity were well controlled. In this observational study in clinical practice, the inclusion criteria were based on ultrasound disease activity and clinical disease activity, set as low or remission (Disease Activity Score in 28 joints based on erythrocyte sedimentation rate <3.2). Ultrasound was performed in 22 joints of bilateral hands at discontinuation for evaluating synovitis severity and presence of bone erosion. Patients with a maximum PD score ≤1 in each joint were enrolled. Forty patients with RA were consecutively recruited (November 2010-March 2015) and discontinued bDMARD therapy. Variables at the initiation and discontinuation of bDMARD therapy that were predictive of relapse during the 12 months after discontinuation were assessed. The median patient age was 54.5 years, and the median disease duration was 3.5 years. Nineteen (47.5%) patients relapsed during the 12 months after the discontinuation of bDMARD therapy. Logistic regression analysis revealed that only the presence of bone erosion detected by ultrasound at discontinuation was predictive of relapse (OR 8.35, 95% CI 1.78-53.2, p = 0.006). No clinical characteristics or serologic biomarkers were significantly different between the relapse and nonrelapse patients. The ultrasound synovitis scores did not differ significantly between the groups. Our findings are the first evidence that ultrasound bone erosion may be a relapse risk factor after the discontinuation of bDMARD therapy in patients with RA whose PD synovitis activity and clinical disease activity are well controlled.

Purpose: To report the long-term outcome and patterns of relapse of a large cohort of marginal zone lymphoma (MZL) patients treated with curative-intent radiation therapy (RT) alone. Patients and Methods: We reviewed the charts of 490 consecutive patients with stage IE or IIE MZL referred between 1992 and 2012 to our institution. Of those, 244 patients (50%) were treated with RT alone. Pathology was confirmed by hematopathologists at our institution. Patient and disease factors were analyzed for association with relapse-free survival (RFS) and overall survival (OS). Results: Median age of the cohort was 59 years, and median follow-up was 5.2 years. Annmore » Arbor stage was IE in 92%. Most common disease sites were stomach (50%), orbit (18%), non-thyroid head-and-neck (8%), skin (8%), and breast (5%). Median RT dose was 30 Gy. Five-year OS and RFS were 92% and 74%, respectively. Cumulative incidence of disease-specific death was just 1.1% by 5 years. Sixty patients (24%) developed relapse of disease; 10 were in the RT field. Crude rate of transformation to pathologically confirmed large-cell lymphoma was 1.6%. On multivariable analysis, primary disease site (P=.007) was independently associated with RFS, along with age (P=.04), presence of B-symptoms (P=.02), and International Prognostic Index risk group (P=.03). All disease sites except for head-and-neck had worse RFS relative to stomach. Conclusion: Overall and cause-specific survival are high in early-stage extra-nodal MZL treated with curative RT alone. In this large cohort of 244 patients, most patients did not experience relapse of MZL after curative RT; when relapses did occur, the majority were in distant sites. Stomach cases were less likely to relapse than other anatomic sites. Transformation to large-cell lymphoma was rare.« less

Seborrheic dermatitis is a chronic inflammatory disease aggravated by Malassezia species. Toll-like receptors (TLR) are part of innate immune system that can be activated by yeasts. Previous studies showed that an association of Umbelliferae extract with a lipid (TLR2-Regul™) decreases the IL-8 expression in human skin in contact with M. furfur. The aim of this study was to assess the activity of a topical formulated with TLR2-Regul™ in the prevention of seborrheic dermatitis (SD) relapses. Immune-competent SD adult patients were treated for SD (topical imidazoles or steroids). Cleared patients were randomized and received a topical containing TLR2-Regul™ (A) or its vehicle (B). Erythema, scales and pruritus were assessed during two months. The study included 115 patients, mean age 43.4, sex ratio m/f 1.5. At week 4 the relapse rate was 26% (N.=15) in group A and 43% (N.=25) in group B. At W8 the relapse rate was 21% (N.=12) in group A and 40% (N.=23) (P=0.0309). In this series of 115 adults with seborrheic dermatitis, patients treated with a topical containing TLR-Regul™ showed a significantly less relapse rate compared with the excipient group (P<0.05). TLR modulation could represent a new therapeutic approach in the prevention of seborrheic dermatitis relapses.

To characterize the mutational patterns of acute lymphoblastic leukemia (ALL) we performed deep next generation sequencing of 872 cancer genes in 172 diagnostic and 24 relapse samples from 172 pediatric ALL patients. We found an overall greater mutational burden and more driver mutations in T-cell ALL (T-ALL) patients compared to B-cell precursor ALL (BCP-ALL) patients. In addition, the majority of the mutations in T-ALL had occurred in the original leukemic clone, while most of the mutations in BCP-ALL were subclonal. BCP-ALL patients carrying any of the recurrent translocations ETV6-RUNX1, BCR-ABL or TCF3-PBX1 harbored few mutations in driver genes compared to other BCP-ALL patients. Specifically in BCP-ALL, we identified ATRX as a novel putative driver gene and uncovered an association between somatic mutations in the Notch signaling pathway at ALL diagnosis and increased risk of relapse. Furthermore, we identified EP300, ARID1A and SH2B3 as relapse-associated genes. The genes highlighted in our study were frequently involved in epigenetic regulation, associated with germline susceptibility to ALL, and present in minor subclones at diagnosis that became dominant at relapse. We observed a high degree of clonal heterogeneity and evolution between diagnosis and relapse in both BCP-ALL and T-ALL, which could have implications for the treatment efficiency.

Childhood acute lymphoblastic leukemia survival approaches 90%. New strategies are needed to identify the 10-15% who evade cure. We applied targeted, sequencing-based genotyping of 25 000 to 34 000 preselected potentially clinically relevant single-nucleotide polymorphisms (SNPs) to identify host genome profiles associated with relapse risk in 352 patients from the Nordic ALL92/2000 protocols and 426 patients from the German Berlin-Frankfurt-Munster (BFM) ALL2000 protocol. Patients were enrolled between 1992 and 2008 (median follow-up: 7.6 years). Eleven cross-validated SNPs were significantly associated with risk of relapse across protocols. SNP and biologic pathway level analyses associated relapse risk with leukemia aggressiveness, glucocorticosteroid pharmacology/response and drug transport/metabolism pathways. Classification and regression tree analysis identified three distinct risk groups defined by end of induction residual leukemia, white blood cell count and variants in myeloperoxidase (MPO), estrogen receptor 1 (ESR1), lamin B1 (LMNB1) and matrix metalloproteinase-7 (MMP7) genes, ATP-binding cassette transporters and glucocorticosteroid transcription regulation pathways. Relapse rates ranged from 4% (95% confidence interval (CI): 1.6-6.3%) for the best group (72% of patients) to 76% (95% CI: 41-90%) for the worst group (5% of patients, P<0.001). Validation of these findings and similar approaches to identify SNPs associated with toxicities may allow future individualized relapse and toxicity risk-based treatments adaptation.

Relapse in people with schizophrenia is a major challenge for mental health service providers in Tanzania and other countries. Approximately 10% of people with schizophrenia are re-admitted due to relapse at Muhimbili National Hospital (MNH) Psychiatric Unit each month. Relapse brings about negative effects and it results in a huge burden to patients, their families, the mental health sector and the country's economy. So far no study has been done to address relapse in Tanzania. The purpose of the study was to explore perspectives on risk and protective factors influencing relapse of people with schizophrenia and their caregivers attending Muhimbili National Hospital Psychiatric Out-patient Department, Dar es Salaam, Tanzania. A qualitative study was conducted, involving in-depth interviews of seven people with schizophrenia who are out-patients and their seven family caregivers at MNH. Purposive sampling procedure was used to select participants for the study. Audio recorded in-depth interviews in Swahili language were conducted with all study participants. The recorded information was transcribed and analyzed using NVivo 9 computer assisted qualitative data analysis software. Personal risk and protective factors for relapse, environmental risk and protective factors for relapse and suggestions to reduce relapse were the main themes that emerged from this study. People with schizophrenia and their caregivers (all of whom were relatives) perceived non adherence to antipsychotic medication as a leading risk factor of relapse; other risks included poor family support, stressful life events and substance use. Family support, adherence to antipsychotic medication, employment and religion were viewed as protective factors. Participants suggested strengthening mental health psycho-education sessions and community home visits conducted by mental health nurses to help reduce relapse. Other suggestions included strengthening the nurse-patient therapeutic relationship in provision of mental health care. This study calls for improvement in mental health care service delivery to individuals with schizophrenia. Establishing a curricular in mental health nursing that aims to produce competent mental health nurse force would improve nursing practice in mental health care service delivery.

Anterior spaces may interfere with smile attractiveness and compromise dentofacial harmony. They are among the most frequent reasons why patients seek orthodontic treatment. However, midline diastema is commonly cited as a malocclusion with high relapse incidence by orthodontists. Objectives This study aimed to evaluate the stability of maxillary interincisor diastemas closure and the association of their relapse and interincisor width, overjet, overbite and root parallelism. Material and Methods Sample comprised 30 patients with at least a pretreatment midline diastema of 0.5 mm or greater after eruption of the maxillary permanent canines. Dental casts and panoramic radiographs were taken at pretreatment, posttreatment and postretention. Results Before treatment, midline diastema width was 1.52 mm (SD=0.88) and right and left lateral diastema widths were 0.55 mm (SD=0.56) and 0.57 mm (SD=0.53), respectively. According to repeated measures analysis of variance, only midline diastema demonstrated significant relapse. In the overall sample the average relapse of midline diastema was 0.49 mm (SD=0.66), whilst the unstable patients showed a mean space reopening of 0.78 mm (SD=0.66). Diastema closure in the area between central and lateral incisors showed great stability. Multivariate correlation tests showed that only initial diastema width (β=0.60) and relapse of overjet (β=0.39) presented association with relapse of midline diastema. Conclusions Midline diastema relapse was statistically significant and occurred in 60% of the sample, while lateral diastemas closure remained stable after treatment. Only initial diastema width and overjet relapse showed association with relapse of midline diastema. There was no association between relapse of interincisor diastema and root parallelism.

Tan, J H; Yeh, B I; Seet, C S R

2010-02-01

Deafness is a common and often permanent neurological sequel of Streptococcus (S.) suis meningitis. Suppurative labyrinthitis, rather than direct auditory nerve infection, has been found to be the site responsible for deafness. Neuroimaging is important to localise the site involved in hearing loss and to assess the feasibility of a cochlear implantation. S. suis is very sensitive to penicillin. Although a relapse of S. suis meningitis is uncommon, it can occur despite an adequate duration of appropriate antibiotic therapy. We describe a patient with S. suis meningitis, who developed permanent deafness from haemorrhagic labyrinthitis, as shown on magnetic resonance imaging. She suffered a relapse despite a seven-week course of intravenous antibiotics. A review on six cases of relapse reported in the literature shows that relapses occurred despite two to four weeks of antibiotics being administered to the patients. The clinical implications and treatment of relapse are discussed.

Schizophrenia is a devastating and costly illness that affects 1% of the population in the US. Effective pharmacological therapies are available but suboptimal patient adherence to either acute or long-term therapeutic regimens reduces their effectiveness. The availability of a long-acting injection (LAI) formulation of risperidone may increase adherence and improve clinical and economic outcomes for people with schizophrenia. To assess the cost effectiveness of risperidone LAI compared with oral risperidone, oral olanzapine and haloperidol decanoate LAI over a 1-year time period in outpatients with schizophrenia who had previously suffered a relapse requiring hospitalisation. US healthcare system. Published medical literature, unpublished data from clinical trials and a consumer health database, and a clinical expert panel were used to populate a decision-analysis model comparing the four treatment alternatives. The model captured: rates of patient compliance; rates, frequency and duration of relapse; incidence of adverse events (bodyweight gain and extrapyramidal effects); and healthcare resource utilisation and associated costs. Primary outcomes were: the proportion of patients with relapse; the frequency of relapse per patient; the number of relapse days per patient; and total direct medical cost per patient per year. Costs are in year 2002 US dollars. Based on model projections, the proportions of patients experiencing a relapse requiring hospitalisation after 1 year of treatment were 66% for haloperidol decanoate LAI, 41% for oral risperidone and oral olanzapine and 26% for risperidone LAI, while the proportion of patients with a relapse not requiring hospitalisation were 60%, 37%, 37% and 24%, respectively. The mean number of days of relapse requiring hospitalisation per patient per year was 28 for haloperidol decanoate LAI, 18 for oral risperidone and oral olanzapine and 11 for risperidone LAI, while the mean number of days of relapse not requiring hospitalisation was 8, 5, 5 and 3, respectively. This would translate into direct medical cost savings with risperidone LAI compared with oral risperidone, oral olanzapine and haloperidol decanoate LAI of USD 397, USD 1742, and USD 8328, respectively. These findings were supported by sensitivity analyses. The use of risperidone LAI for treatment of outpatients with schizophrenia is predicted in this model to result in better clinical outcomes and lower total healthcare costs over 1 year than its comparators, oral risperidone, oral olanzapine and haloperidol decanoate LAI. Risperidone LAI may therefore be a cost saving therapeutic option for outpatients with schizophrenia in the US healthcare setting.

Background High-dose chemotherapy followed by autologous stem cell transplantation is the standard treatment for relapsed and/or refractory Hodgkin’s lymphoma although half of patients relapse after transplantation. Predictive factors, such as relapse within 12 months, Ann-Arbor stage at relapse, and relapse in previously irradiated fields are classically used to identify patients with poor outcome. Recently, 18-fluorodeoxyglucose positron emission tomography has emerged as a new method for providing information to predict outcome. The aim of this study was to confirm the predictive value of positron emission tomography status after salvage therapy and to compare single versus tandem autologous stem cell transplantation in patients with relapsed and/or refractory Hodgkin’s lymphoma. Design and Methods We report a series of 111 consecutive patients with treatment-sensitive relapsed and/or treatment-refractory Hodgkin’s lymphoma who achieved complete (positron emission tomography-negative group) or partial remission (positron emission tomography-positive group) at positron emission tomography evaluation after salvage chemotherapy and who underwent single or tandem autologous stem cell transplantation. Results Five-year overall and progression-free survival rates were 81% and 64%, respectively. There were significant differences in 5-year progression-free survival (79% versus 23%; P<0.001) and 5-year overall survival (90% versus 55%, P=0.001) between the positron emission tomography-negative and -positive groups, respectively. A complete response, as determined by positron emission tomography evaluation, after salvage therapy predicted significantly better 5-year overall survival rates in both intermediate (91% versus 50%; P=0.029) and unfavorable (89% versus 58%; P=0.026) risk subgroup analyses. In the positron emission tomography-positive subgroup, tandem transplantation improved 5-year progression-free survival from 0% (in the single transplantation group) to 43% (P=0.034). Multivariate analysis showed that positron emission tomography status (hazard ratio: 5.26 [2.57–10.73]) and tandem transplantation (hazard ratio: 0.39 [0.19–0.78]) but not risk factors at relapse (hazard ratio: 1.77 [0.80–3.92]) significantly influenced progression-free survival, while only tomography status significantly influenced overall survival (hazard ratio: 4.03 [1.38–11.75]). Conclusions In patients with relapsed/refractory Hodgkin’s lymphoma responding to prior salvage therapy, positron emission tomography response at time of autologous stem cell transplantation favorably influences outcome and enables identification of patients requiring single or tandem transplantation.

Novel Immunotherapies for Autoimmune Hepatitis

2017-01-01

Autoimmune hepatitis (AIH) is a multifactorial autoimmune disease of unknown pathogenesis, characterized by a loss of immunological tolerance against liver autoantigens resulting in the progressive destruction of the hepatic parenchyma. Current treatments are based on non-specific immunosuppressive drugs. Although tremendous progress has been made using specific biological agents in other inflammatory diseases, progress has been slow to come for AIH patients. While current treatments are successful in the majority of patients, treatment discontinuation is difficult to achieve, and relapses are frequent. Lifelong immunosuppression is not without risks, especially in the pediatric population; 4% of patient with type 1 AIH will eventually develop hepatocellular carcinoma with a 2.9% probability after 10 years of treatment. Therefore, future treatments should aim to restore tolerance to hepatic autoantigens and induce long-term remission. Promising new immunotherapies have been tested in experimental models of AIH including T and B cell depletion and regulatory CD4+ T cells infusion. Clinical studies on limited numbers of patients have also shown encouraging results using B-cell-depleting (rituximab) and anti-TNF-α (infliximab) antibodies. A better understanding of key molecular targets in AIH combined with effective site-specific immunotherapies could lead to long-term remission without blanket immunosuppression and with minimal deleterious side effects.

This report presents the 4th documented case worldwide of herpes simplex encephalitis in multiple sclerosis (MS) patients treated with natalizumab and the first case in the UK. Natalizumab is licensed for relapsing remitting multiple sclerosis in patients with high disease activity despite treatment with interferon-beta and patients with rapidly evolving severe, multiple sclerosis. Natalizumab is a monoclonal antibody targeted against alpha-4 integrin. Its proposed mechanism is attenuation of the migration of immune cells into the central nervous system. Reactivation of the JC virus causing progressive multifocal leucoencephalopathy (PML) and its association with natalizumab is well documented. This case adds support to the suggestion that natalizumab also increases the reactivation risk of CNS herpes simplex infection. A 34 year old woman was admitted with a generalized tonic-clonic seizure, fever and confusion following her 40th infusion of natalizumab. MRI demonstrated increased signal in the medial temporal lobes and EEG showed focal sharp waves over the temporal lobe. CSF PCR later confirmed herpes simplex virus. The patient made an eventual excellent recovery following 21 days of intravenous acyclovir therapy followed by 14 days of oral treatment. Crown Copyright © 2013. Published by Elsevier B.V.

Neurocognitive rehabilitation for addiction medicine: From neurophysiological markers to cognitive rehabilitation and relapse prevention.

PubMed

Campanella, Salvatore

2016-01-01

Currently, relapse prevention remains the main challenge in addiction medicine, indicating that the established treatment methods combining psychotherapy with neuropharmacological interventions are not entirely effective. Therefore, there is a push to develop alternatives to psychotherapy- and medication-based approaches to addiction treatment. Two major cognitive factors have been identified that trigger relapse in addicted patients: attentional biases directed toward drug-related cues, which increase the urge to consume, and impaired response inhibition toward these cues, which makes it more difficult for addicted people to resist temptation. Recent studies on newly detoxified alcoholic patients have shown that by using the appropriate tasks to index these cognitive functions with event-related potentials (ERPs), it is possible to discriminate between future relapsers and nonrelapsers. These preliminary data suggest that the ERP technique has great clinical potential for preventing relapse in alcohol-dependent patients, as well as for addictive states in general. Indeed, ERPs may help to identify patients highly vulnerable to relapse and allow the development of individually adapted cognitive rehabilitation programs. The implementation of this combined approach requires an intense collaboration between psychiatry departments, clinical neurophysiology laboratories, and neuropsychological rehabilitation centers. The potential pitfalls and limitations of this approach are also discussed. © 2016 Elsevier B.V. All rights reserved.

Prevention of relapse in patients with congestive heart failure: the role of precipitating factors

Relapse of congestive heart failure (CHF) frequently occurs and has serious consequences in terms of morbidity, mortality, and health care expenditure. Many studies have investigated the aetiological and prognostic factors of CHF, but there are only limited data on the role of precipitating factors that trigger relapse of CHF. Knowledge of potential precipitating factors may help to optimise treatment and provide guidance for patients with CHF. The literature was reviewed to identify factors that may influence haemodynamic homeostasis in CHF. Precipitating factors that may offer opportunities for preventing relapse of CHF were selected. Potential precipitating factors are discussed in relation to the pathophysiology of CHF: alcohol, smoking, psychological stress, uncontrolled hypertension, cardiac arrhythmias, myocardial ischaemia, poor treatment compliance, and inappropriate medical treatment. Poor treatment compliance in particular is frequently encountered in patients with CHF. Furthermore, studies of medical treatment under everyday circumstances indicate that some aspects of the management of CHF can be improved. In conclusion, the identification of precipitating factors for relapse of CHF may strongly contribute to optimal treatment. Improvement of treatment compliance and optimalisation of medical treatment may offer important possibilities to clinicians to reduce the number of relapses in patients with CHF.

We have previously hypothesized that higher systemic exposure to asparaginase may cause increased exposure to dexamethasone, both critical chemotherapeutic agents for acute lymphoblastic leukemia. Whether interpatient pharmaco-kinetic differences in dexamethasone contribute to relapse risk has never been studied. The impact of plasma clearance of dexamethasone and anti–asparaginase antibody levels on risk of relapse was assessed in 410 children who were treated on a front-line clinical trial for acute lymphoblastic leukemia and were evaluable for all pharmacologic measures, using multivariate analyses, adjusting for standard clinical and biologic prognostic factors. Dexamethasone clearance (mean ± SD) was higher (P = 3 × 10−8) in patients whose sera was positive (17.7 ± 18.6 L/h per m2) versus nega-tive (10.6 ± 5.99 L/h per m2) for anti–asparaginase antibodies. In multivariate analyses, higher dexamethasone clearance was associated with a higher risk of any relapse (P = .01) and of central nervous system relapse (P = .014). Central nervous system relapse was also more common in patients with anti–asparaginase antibodies (P = .019). In conclusion, systemic clearance of dexamethasone is higher in patients with anti–asparaginase antibodies. Lower exposure to both drugs was associated with an increased risk of relapse.

The chronic and relapsing nature of vulvar lichen sclerosus (VLS) represents a challenge for its long-term management after an effective treatment with topical corticosteroids. To compare the effect of topical vitamin E with that of an emollient in reducing the risk of VLS relapse over a 52-week maintenance treatment. 156 patients with VLS were enrolled in a 12-week active treatment phase on topical 0.1% mometasone furoate ointment once daily. Those who achieved disease remission entered a 52-week maintenance phase in which patients were randomized to apply either an emollient or topical vitamin E once daily. 80 patients entered the maintenance phase. At 52 weeks, for the vitamin E maintenance group, the cumulative crude relapse rate was 27.8% and the cumulative modified crude relapse rate was 55.6%. For the emollient maintenance group, the cumulative crude relapse rate was 22.7% and the cumulative modified crude relapse rate was 50.0%. The median time to relapse was 20 weeks for the vitamin E group and 18.7 weeks for the emollient group. Once VLS has been stabilized with topical corticosteroids, long-term treatment with both vitamin E and emollients may be considered in maintain LS remission.

Extranodal NK/T-cell lymphoma, nasal type, is a rare and highly aggressive disease with a grim prognosis. No therapeutic strategy is currently identified in relapsing patients. We report the results of a French prospective phase II trial of an L-asparaginase-containing regimen in 19 patients with relapsed or refractory disease treated in 13 centers. Eleven patients were in relapse and 8 patients were refractory to their first line of treatment. L-Asparaginase-based treatment yielded objective responses in 14 of the 18 evaluable patients after 3 cycles. Eleven patients entered complete remission (61%), and only 4 of them relapsed. The median overall survival time was 1 year, with a median response duration of 12 months. The main adverse events were hepatitis, cytopenia, and allergy. The absence of antiasparaginase antibodies and the disappearance of Epstein-Barr virus serum DNA were significantly associated with a better outcome. These data confirm the excellent activity of L-asparaginase-containing regimens in extranodal NK/T-cell lymphoma. L-Asparaginase-based treatment should thus be considered for salvage therapy, especially in patients with disseminated disease. First-line L-asparaginase combination therapy for extranodal NK/T-cell lymphoma warrants evaluation in prospective trials. This trial is registered at www.clinicaltrials.gov as #NCT00283985.

The optimal choice of salvage therapy for patients with relapsed/refractory diffuse large B-cell lymphoma (DLBCL) or Hodgkin lymphoma (HL) remains unknown. Based on promising results of phase II trials, the preferred salvage regimen in British Columbia since 2002 has been the out-patient regimen, gemcitabine, dexamethasone, and cisplatin (GDP). We conducted a retrospective analysis including all patients with relapsed/refractory DLBCL or HL who received GDP as salvage therapy between September 2002 and June 2010. We identified 235 patients: 152 DLBCL, 83 HL. Overall response rates were 49% and 71% for patients with DLBCL and HL, respectively. Within the transplant-eligible population, 52% of patients with DLBCL and 96% of patients with HL proceeded to stem cell transplantation. The 2-year progression-free survival and overall survival were 21% and 28% in the DLBCL cohort, and 58% and 85% in the HL group. GDP is an effective and well-tolerated out-patient salvage regimen for relapsed/refractory DLBCL and HL.

Resilience Associated with Self-Disclosure and Relapse Risks in Patients with Alcohol Use Disorders.

2016-12-01

The aim of this study was to clarify the self-disclosure and risks of relapse associated with promoting resilience of patients with alcohol use disorders (AUD) and participating in self-help groups. An anonymous, self-administered questionnaire survey was administered to 48 patients with AUD and participating in self-help groups; this questionnaire consisted of basic attributes, a bidimensional resilience scale to assess both innate and acquired resilience factors, a scale to assess depth of self-disclosure, and a scale assessing relapse risks. We conducted an evaluation by dividing the respondents into a high group and low group based on their median values for both innate and acquired resilience. Innate/acquired resilience had a mutually reinforcing relationship, and, compared with the low resilience group, the high resilience group had significantly reduced risks for relapses and resulted in deeper self-disclosure. Patients with high resilience had lower risk of alcohol relapse and deeper self-disclosure. The results suggest that one way of supporting patients with AUD in recovery is assisting them in building personal relationships with others and in deepening self-disclosure in a setting where they can relax, thus promoting their natural ability to recover.

Reduction of Breast Cancer Relapses with Perioperative Non-Steroidal Anti-Inflammatory Drugs: New Findings and a Review

To explain a bimodal pattern of hazard of relapse among early stage breast cancer patients identified in multiple databases, we proposed that late relapses result from steady stochastic progressions from single dormant malignant cells to avascular micrometastases and then on to growing deposits. However in order to explain early relapses, we had to postulate that something happens at about the time of surgery to provoke sudden exits from dormant phases to active growth and then to detection. Most relapses in breast cancer are in the early category. Recent data from Forget et al. suggest an unexpected mechanism. They retrospectively studied results from 327 consecutive breast cancer patients comparing various perioperative analgesics and anesthetics in one Belgian hospital and one surgeon. Patients were treated with mastectomy and conventional adjuvant therapy. Relapse hazard updated Sept 2011 are presented. A common Non-Steroidal Anti-Inflammatory Drug (NSAID) analgesic used in surgery produced far superior disease-free survival in the first 5 years after surgery. The expected prominent early relapse events in months 9-18 are reduced 5-fold. If this observation holds up to further scrutiny, it could mean that the simple use of this safe, inexpensive and effective anti-inflammatory agent at surgery might eliminate early relapses. Transient systemic inflammation accompanying surgery could facilitate angiogenesis of dormant micrometastases, proliferation of dormant single cells, and seeding of circulating cancer stem cells (perhaps in part released from bone marrow) resulting in early relapse and could have been effectively blocked by the perioperative anti-inflammatory agent.

Background. Recurrent tuberculosis is a major health burden and may be due to relapse with the original strain or reinfection with a new strain. Methods. In a population-based study in northern Malawi, patients with tuberculosis diagnosed from 1996 to 2010 were actively followed after the end of treatment. Whole-genome sequencing with approximately 100-fold coverage was performed on all available cultures. Results of IS6110 restriction fragment-length polymorphism analyses were available for cultures performed up to 2008. Results. Based on our data, a difference of ≤10 single-nucleotide polymorphisms (SNPs) was used to define relapse, and a difference of >100 SNPs was used to define reinfection. There was no evidence of mixed infections among those classified as reinfections. Of 1471 patients, 139 had laboratory-confirmed recurrences: 55 had relapse, and 20 had reinfection; for 64 type of recurrence was unclassified. Almost all relapses occurred in the first 2 years. Human immunodeficiency virus infection was associated with reinfection but not relapse. Relapses were associated with isoniazid resistance, treatment before 2007, and lineage-3 strains. We identified several gene variants associated with relapse. Lineage-2 (Beijing) was overrepresented and lineage-1 underrepresented among the reinfecting strains (P = .004). Conclusions. While some of the factors determining recurrence depend on the patient and their treatment, differences in the Mycobacterium tuberculosis genome appear to have a role in both relapse and reinfection.

Background—The relapse rate after steroid induced remission in Crohn's disease is high. 
Aims—To test whether oral pH modified release budesonide (3 × 1 mg/day) reduces the relapse rate and to identify patient subgroups with an increased risk of relapse. 
Methods—In a multicentre, randomised, double blind study, 179 patients with steroid induced remission of Crohn's disease received either 3 × 1 mg budesonide (n=84) or placebo (n=95) for one year. The primary study aim was the maintenance of remission of Crohn's disease for one year. 
Results—Patient characteristics at study entry were similar for both groups. The relapse rate was 67% (56/84) in the budesonide group and 65% (62/95) in the placebo group. The relapse curves in both groups were similar. The mean time to relapse was 93.5days in the budesonide group and 67.0 days in the placebo group. No prognostic factors allowing prediction of an increased risk for relapse or definition of patient subgroups who derived benefit from low dose budesonide were found. Drug related side effects were mild and no different between the budesonide and the placebo group. 
Conclusion—Oral pH modified release budesonide at a dose of 3 × 1 mg/day is not effective for maintaining steroid induced remission in Crohn's disease.

In patients with relapsed acute promyelocytic leukemia (APL), the best consolidation regimen following induction of remission with arsenic trioxide (ATO) remains to be defined. Since January 2000, 37 patients with relapsed APL were treated at our center. The median age was 34 years (range, 6-57 years), and there were 20 males (54.1%). The median duration of first remission was 20.3 months (range, 2.9-81.2 months). Relapse was treated with single-agent ATO in 22 patients (59.5%), ATO+ATRA in 5 patients (13.5%), and ATO+ATRA + anthracycline in 10 patients (27%). Thirty-three patients (89%) achieved molecular remission after induction and a consolidation course. Fourteen patients opted to undergo autologous stem cell transplantation (SCT), and the remaining 19 patients received monthly cycles of ATO as a single agent (n=13) or ATO+ATRA (n=6) for 6 months. At a median follow-up of 32 months, the 5-year Kaplan-Meier estimate of event-free survival (EFS) was 83.33% +/- 15.21% in those who underwent autologous SCT versus 34.45% +/- 11.24% in those who did not (P=.001; log-rank test). Following remission induction with ATO-based regimens in patients with relapsed APL, consolidation with autologous SCT is associated with a significantly superior clinical outcome compared with ATO- and ATO+ATRA-based maintenance regimens.

The role of auto-SCT in the treatment of multiple myeloma (MM) in the era of novel agents continues to evolve. It is now clear that the depth of response and clinical outcomes have significantly improved as a result of the combination of these strategies. However, not all patients with MM who undergo auto-SCT are able to sustain a meaningful response and 20% of patients relapse shortly after auto-SCT. In this study, we aimed to assess the impact of early relapse (ER) after auto-SCT on OS for MM patients undergoing single auto-SCT who had received novel agent-based induction regimens. All consecutive patients with MM undergoing single auto-SCT from January 2002 to September 2012 who had novel induction therapy were evaluated. A total of 184 patients were identified. The median OS and PFS for the group of transplanted patients were 93 and 25.4 months, respectively. Median time to relapse was 17.2 months with 40% having relapsed at the time of analysis. ER (<12 months post auto-SCT) was seen in 27 (36%) out of 75 patients who had relapsed, and median OS was significantly shorter than in those with non-ER. Multivariate analysis showed ER as the major independent prognostic factor for OS. On the basis of these findings, we conclude that not only attainment of a good response, but sustainability of it, appears to be a major prognostic variable in MM in the era of novel therapy. Patients with ER post auto-SCT should biologically be characterized in prospective studies to better understand the mechanisms of resistance associated with this particular entity.

The present study sought to elucidate the prognosis of adult T-cell leukemia-lymphoma (ATL) patients receiving mogamulizumab, a defucosylated anti-CCR4 monoclonal antibody. Progression-free survival (PFS) and overall survival (OS) of ATL patients enrolled in two studies are herein updated, namely NCT00355472 (phase I study of mogamulizumab in relapsed patients with ATL and peripheral T-cell lymphoma) and NCT00920790 (phase II study for relapsed ATL). Of 13 patients with relapsed aggressive ATL in the phase I study, four (31%) survived >3 years. For 26 relapsed patients with aggressive ATL in the phase II study, median PFS was 5.2 months and 1-year PFS was 26%, whereas median OS was 14.4 months, and 3-year OS was 23%. For patients without a rash or who developed a grade 1 rash only, median PFS was 0.8 months, and 1-year PFS was zero, with a median OS of 6.0 months, and 3-year OS of 8%. In contrast, for patients who developed a rash ≥grade 2, median PFS was 11.7 months, and 1-year PFS was 50%, with a median OS of 25.6 months, and 3-year OS of 36%. Thus, we conclude that mogamulizumab monotherapy may improve PFS and OS in some patients with relapsed aggressive ATL, especially those who develop a skin rash as a moderate immune-related adverse event. Therefore, further investigation is warranted to validate the present observations and to clarify the mechanisms involved in the activity of mogamulizumab. © 2017 The Authors.

Hemophagocytic lymphohistiocytosis (HLH) is an immune regulatory disorder that commonly presents with central nervous system (CNS) involvement. The only cure for genetic HLH is hematopoietic stem cell transplantation (HSCT), typically treated with reduced-intensity conditioning (RIC) regimens. We sought to estimate the incidence of CNS relapse after RIC HSCT, determine risk factors, and evaluate outcomes. We performed a retrospective chart review of 94 consecutive children and young adults with primary HLH who received RIC HSCT. CNS relapse within 1 year after transplantation was diagnosed by review of clinical symptoms, cerebral spinal fluid (CSF), and radiologic findings. Four (4.25%) patients developed symptoms of possible CNS HLH after HSCT and 3 patients were diagnosed. Eight patients underwent screening lumbar puncture because of history of active CNS disease at the onset of the conditioning regimen and 4 had evidence of continued disease. The overall incidence of CNS relapse and continued CNS disease after RIC HSCT was 8%. All patients with CNS disease after HSCT responded to CNS-directed therapy. Whole blood donor chimerism at the time of CNS relapse was low at 1% to 34%, but it remained high at 88% to 100% for patients with continued CNS disease. Overall survival for patients with CNS relapse was 50%, compared with 75% for patients without CNS disease (P = .079). Our data suggest that a low level of donor chimerism or active CNS disease at the time of transplantation increase the risk of CNS HLH after HSCT. Surveillance CSF evaluation after allogeneic RIC HSCT should be considered in patients with risk factors and CNS-directed treatment should be initiated if appropriate.

Pediatric patients with refractory or relapsed metastatic neuroblastoma (NBL) have a poor prognosis despite autologous stem cell transplantation (SCT). Allogeneic SCT from a haploidentical donor has a remarkable alloreactive effect in patients with leukemia; thus, we evaluated this approach in children with very high-risk NBL. We analyzed data from 2 prospective phase I/II trials. A total of 26 patients with refractory (n = 5), metastatic relapsed (n = 20), or locally relapsed MYCN-positive (n = 1) NBL received a median of 17 × 10 6 /kg T/B cell-depleted CD34 + stem cells with 68 × 10 3 /kg residual T cells and 107 × 10 6 /kg natural killer cells. The conditioning regimen comprised melphalan, fludarabine, thiotepa, OKT3, and a short course of mycophenolate mofetil post-transplantation. Engraftment occurred in 96% of the patients. Event-free survival and overall survival at 5 years were 19% and 23%, respectively. No transplantation-related mortality was observed, and the single death was due to progression/subsequent relapse. The median duration of follow-up was 8.1 years. Patients in complete remission before SCT had a significantly better prognosis than those with residual tumor load (P < .01). All patients with progressive disease before SCT relapsed within 1 year. Grade II and grade III acute graft-versus-host disease (GVHD) occurred in 31% and 12% of the patients, respectively. Chronic limited and extensive GVHD occurred in 28% and 10%, respectively. Our data indicate that haploidentical SCT is a feasible treatment option that can induce long-term remission in some patients with NBL with tolerable side effects, and may enable the development of further post-transplantation therapeutic strategies based on the donor-derived immune system.

Fermented milk products containing Bifidobacterium breve strain Yakult (BFM) may improve clinical status in ulcerative colitis (UC) patients. To assess efficacy of BFM in maintaining remission in Japanese patients with quiescent UC. This double-blind study (B-FLORA) enrolled 195 patients with quiescent UC, randomized to receive one pack of BFM fermented milk per day [Bifidobacterium breve strain Yakult (10 billion bacteria) and Lactobacillus acidophilus (1 billion bacteria)] (n = 98) or matching placebo (n = 97) for 48 weeks. The primary efficacy endpoint was relapse-free survival (relapse: rectal bleeding score ≥ 2 on Sutherland disease activity index scale for 3 consecutive days and/or initiation of remission induction therapy for worsening of UC). An interim analysis was conducted after inclusion and follow-up of one-third of patients for the first phase of the study (n = 195). Relapse-free survival was not significantly different between the BFM and placebo groups (P = 0.643; hazard ratio 1.16; 95% CI 0.63-2.14, log-rank test), nor was the incidence of relapse. Therefore, the study was discontinued for lack of efficacy. An exploratory analysis of fecal samples from a subgroup of patients revealed no effects of either study beverage on intestinal microbiota, but there was a significant decrease in Bifidobacterium species before relapse, regardless of treatment group. Three mild adverse events occurred for which a causal relationship with the study beverage could not be ruled out (placebo: abdominal bloating and stress in one patient; BFM: body odor in one patient). BFM had no effect on time to relapse in UC patients compared with placebo. UMIN000007593.

Background The management of patients with chronic hepatitis C who have relapsed or failed to respond to interferon based therapies is an important issue facing hepatologists. Aims We evaluated the efficacy and safety of peginterferon alfa‐2a (40KD) plus ribavirin in this population by conducting a multicentre open label study. Patients Data from adults with detectable serum hepatitis C virus (HCV) RNA who had not responded or had relapsed after previous conventional interferon or conventional interferon/ribavirin combination therapy were analysed. Methods Patients were retreated with peginterferon alfa‐2a (40KD) 180 µg/week plus ribavirin 800 mg/day for 24 or 48 weeks at the investigators' discretion. The study was conceived before the optimal dose of ribavirin (1000/1200 mg/day) for patients with genotype 1 was known. The primary endpoint was sustained virological response (SVR), defined as undetectable HCV RNA (<50 IU/ml) after 24 weeks of follow up. The analysis was conducted by intention to treat. Results A total of 312 patients (212 non‐responders, 100 relapsers) were included. Of these, 28 patients were treated for 24 weeks and 284 for 48 weeks. Baseline characteristics between non‐responders and relapsers were similar although more non‐responders had genotype 1 infection (87% v 69%). Overall SVR rates were 23% (48/212) for non‐responders and 41% (41/100) for relapsers. When data were analysed by genotype, SVR rates were 24% (61/253) in genotype 1 and 47% (28/59) in genotype 2/3. Conclusions These results in a large patient cohort demonstrate that it is possible to cure a proportion of previous non‐responders and relapsers by retreating with peginterferon alfa‐2a (40KD) plus ribavirin.

Patients with ulcerative colitis (UC) who achieve remission with corticosteroids often relapse after tapering or discontinuation; alternative treatments limiting steroid exposure and UC relapse would be beneficial. It remains uncertain whether patients with corticosteroid-induced remission experience benefit with mesalamine granules (MG), a locally acting aminosalicylate extended-release capsule formulation for maintenance of UC remission in adults. Efficacy and safety of MG 1.5 g once daily was evaluated in patients with UC in corticosteroid-induced remission. Data from patients with previous corticosteroid use to achieve baseline UC remission were analyzed from two 6-month randomized, double-blind, placebo-controlled trials and a 24-month open-label extension (OLE). Six-month relapse-free rates were assessed using the revised Sutherland Disease Activity Index. UC-related adverse events (AEs) were recorded during the 30 months. Included were 158 steroid-treated patients in UC remission (MG, n = 105; placebo, n = 53) and 74/105 MG-treated patients who continued MG in the OLE. A significantly larger percentage of patients remained relapse-free at 6 months with MG (77.1 %) versus placebo (54.7 %; P = 0.006), with a 55 % reduction in relapse risk (hazard ratio [HR] 0.45; 95 % CI 0.25-0.79). There was a similar (49.2 %) reduction in risk of UC-related AEs at 6 months (HR 0.51; 95 % CI 0.31-0.84; P = 0.009) that was sustained during the OLE. MG 1.5 g once daily administered for maintenance of corticosteroid-induced remission was associated with low risk of relapse and UC-related AEs.

To assess the outcomes of the intravitreal administration of methotrexate in uveitis. Multicenter, retrospective interventional case series of patients with noninfectious uveitis. Thirty-eight eyes of 30 patients were enrolled, including a total of 54 intravitreal injections of methotrexate at a dose of 400 µg in 0.1 mL. The primary outcome measure was visual acuity. Secondary outcome measures included control of intraocular inflammation and cystoid macular edema, time to relapse, development of adverse events, and levels of systemic corticosteroid and immunosuppressive therapy. Methotrexate proved effective in controlling intraocular inflammation and improving vision in 30 of 38 eyes (79%). The side effect profile was good, with no reported serious ocular adverse events and only one patient having an intraocular pressure of >21 mmHg. Of the 30 eyes that responded to treatment, 8 relapsed, but 22 (73%) entered an extended period of remission, with the Kaplan-Meier estimate of median time to relapse for the whole group being 17 months. The eight eyes that relapsed were reinjected and all responded to treatment. One eye relapsed at 3 months, but 7 eyes again entered extended remission. Of the 14 patients on systemic therapy at the start of the study, 8 (57%) were able to significantly reduce this following intravitreal methotrexate injection. In patients with uveitis and uveitic cystoid macular edema, intravitreal MTX can effectively improve visual acuity and reduce cystoid macular edema and, in some patients, allows the reduction of immunosuppressive therapy. Some patients relapse at 3 to 4 months, but a large proportion (73%) enter an extended period of remission of up to 18 months. This larger study extends the results obtained from previous smaller studies suggesting the viability of intravitreal methotrexate as a treatment option in uveitis.

Abstract Although discontinuation of suppressive antifungal therapy for acquired immunodeficiency syndrome (AIDS)-associated histoplasmosis is accepted for patients with immunologic recovery, there have been no published studies of this approach in clinical practice, and minimal characterization of individuals who relapse with this disease. We performed a multicenter retrospective cohort study to determine the outcome in AIDS patients following discontinuation of suppressive antifungal therapy for histoplasmosis. Ninety-seven patients were divided into a physician-discontinued suppressive therapy group (PD) (38 patients) and a physician-continued suppressive therapy group (PC) (59 patients). The 2 groups were not statistically different at baseline, but at discontinuation of therapy and at the most recent follow-up there were significant differences in adherence to therapy, human immunodeficiency virus (HIV) RNA, and urinary Histoplasma antigen concentration. There was no relapse or death attributed to histoplasmosis in the PD group compared with 36% relapse (p < 0.0001) and 5% death (p = 0.28) in the PC group. Relapse occurred in 53% of the nonadherent patients but not in the adherent patients (p < 0.0001). Sixty-seven percent of patients with initial central nervous system (CNS) histoplasmosis relapsed compared to 15% of patients without CNS involvement (p = 0.0004), which may be accounted for by nonadherence. In addition, patients with antigenuria above 2.0 ng/mL at 1-year follow-up were 12.82 times (95% confidence interval, 2.91–55.56) more likely to relapse compared to those with antigenuria below 2.0 ng/mL. Discontinuation of antifungal therapy was safe in adherent patients who completed at least 1 year of antifungal treatment, and had CD4 counts >150 cells/mL, HIV RNA <400 c/mL, Histoplasma antigenuria <2 ng/mL (equivalent to <4.0 units in second-generation method), and no CNS histoplasmosis.

The relative effectiveness and safety profile of the treatments with marketing authorization for relapsing multiple sclerosis (MS) are not well known because randomized controlled trials with head-to-head comparisons between these treatments do not exist. Thus, a network of multiple-treatments meta-analysis was performed using four clinical outcomes: 'patients free of relapse', 'patients without disease progression', 'patients without MRI progression' and 'patients with adverse events'. Randomized controlled trials (RCTs) on MS were systematically searched in PubMed and Cochrane Central Register of Controlled Trial. The network analysis performed pairwise comparisons between the marketed treatments (Betaferon 250mcg, Avonex 30mcg, Rebif 44mcg, Rebif 22mcg, Aubagio 7 mg, Aubagio 14 mg, Copaxone 20 mg, Tysabri 300 mg, Gilenya 0·5 mg and Novantrone 12 mg/m(2)) using direct and indirect analyses. The analysis included 48 articles, involving 20 455 patients with MS. The direct analysis showed better response for more than one outcome for Gilenya compared with Avonex ('patients free of relapse' and 'patients without MRI progression') and for Betaferon compared with Avonex ('patients without disease progression' and 'patients without MRI progression'). The indirect analysis indicated that Tysabri may have better relative effectiveness compared with the other treatments for two outcomes: 'patients free of relapse' and 'patients without MRI progression'. Regarding 'patients with adverse events', no data were available for all comparisons to make fair inferences. This was an attempt, for the first time, to compare the efficacy and safety profile of existing approved treatments for relapsing MS. Although some treatments have shown better response, the results of the network analysis should be interpreted with caution because of the lack of RCTs with head-to-head comparisons between treatments. © 2013 John Wiley & Sons Ltd.

Pazopanib is an oral multikinase inhibitor that has proved effective in adults treated for relapsing soft tissue sarcoma and synovial sarcoma in particular. Two cases are reported here of pediatric patients with pretreated relapsing synovial sarcoma whose tumors showed a prolonged response to pazopanib given on compassionate grounds. These results suggest that new agents found effective in adult patients might achieve similar results in adolescents with the same disease. Facilitating the availability of new drugs for children and adolescents is a major challenge for pediatric oncologists.

Pathogenesis of myelodysplastic syndromes: an overview of molecular and non-molecular aspects of the disease

PubMed Central

Visconte, Valeria; Tiu, Ramon V.

Myelodysplastic syndromes (MDS) are a group of clonal disorders arising from hematopoietic stem cells generally characterized by inefficient hematopoiesis, dysplasia in one or more myeloid cell lineages, and variable degrees of cytopenias. Most MDS patients are diagnosed in their late 60s to early 70s. The estimated incidence of MDS in the United States and in Europe are 4.3 and 1.8 per 100,000 individuals per year, respectively with lower rates reported in some Asian countries and less well estimated in other parts of the world. Evolution to acute myeloid leukemia can occur in 10-15% of MDS patients. Three drugs are currently approved for the treatment of patients with MDS: immunomodulatory agents (lenalidomide), and hypomethylating therapy [HMT (decitabine and 5-azacytidine)]. All patients will eventually lose their response to therapy, and the survival outcome of MDS patients is poor (median survival of 4.5 months) especially for patients who fail (refractory/relapsed) HMT. The only potential curative treatment for MDS is hematopoietic cell transplantation. Genomic/chromosomal instability and various mechanisms contribute to the pathogenesis and prognosis of the disease. High throughput genetic technologies like single nucleotide polymorphism array analysis and next generation sequencing technologies have uncovered novel genetic alterations and increased our knowledge of MDS pathogenesis. We will review various genetic and non-genetic causes that are involved in the pathogenesis of MDS. PMID:25548754

Adults with relapsed or refractory B-precursor acute lymphoblastic leukaemia have an unfavourable prognosis. Blinatumomab is a bispecific T-cell engager antibody construct targeting CD19, an antigen consistently expressed on B-lineage acute lymphoblastic leukaemia cells. We aimed to confirm the activity and safety profile of blinatumomab for acute lymphoblastic leukaemia. In a multicentre, single-arm, open-label phase 2 study, we enrolled adult patients with Philadelphia-chromosome-negative, primary refractory or relapsed (first relapse within 12 months of first remission, relapse within 12 months after allogeneic haemopoietic stem-cell transplantation [HSCT], or no response to or relapse after first salvage therapy or beyond) leukaemia. Patients received blinatumomab (9 μg/day for the first 7 days and 28 μg/day thereafter) by continuous intravenous infusion over 4 weeks every 6 weeks (up to five cycles), per protocol. The primary endpoint was complete remission (CR) or CR with partial haematological recovery of peripheral blood counts (CRh) within the first two cycles. Analysis was by intention to treat. This trial is registered at ClinicalTrials.gov, number NCT01466179. Between Jan 13, 2012, and Oct 10, 2013, 189 patients were enrolled and treated with blinatumomab. After two cycles, 81 (43%, 95% CI 36-50) patients had achieved a CR or CRh: 63 (33%) patients had a CR and 18 (10%) patients had a CRh. 32 (40%) of patients who achieved CR/CRh underwent subsequent allogeneic HSCT. The most frequent grade 3 or worse adverse events were febrile neutropenia (48 patients, 25%), neutropenia (30 patients, 16%), and anaemia (27 patients, 14%). Three (2%) patients had grade 3 cytokine release syndrome. Neurologic events of worst grade 3 or 4 occurred in 20 (11%) and four (2%) patients, respectively. Three deaths (due to sepsis, Escherichia coli sepsis, and Candida infection) were thought to be treatment-related by the investigators. Single-agent blinatumomab showed antileukaemia activity in adult patients with relapsed or refractory B-precursor acute lymphoblastic leukaemia characterised by negative prognostic factors. Further assessment of blinatumomab treatment earlier in the course of the disease and in combination with other treatment approaches is warranted. Amgen. Copyright © 2015 Elsevier Ltd.

The outcome of relapsed adult acute lymphoblastic leukemia (ALL) remains dismal despite new therapeutic approaches. Previous studies analyzing relapse samples have shown a high degree of heterogeneity regarding gene alterations without an evident relapse signature. Bone marrow or peripheral blood samples from 31 adult B-cell precursor ALL patients at first relapse, and 21 paired diagnostic samples were analyzed by multiplex ligation probe-dependent amplification (MLPA). Nineteen paired diagnostic and relapse samples of these 21 patients were also analyzed by SNP arrays. A trend to acquire homozygous CDKN2A/B deletions and a significant increase in the number of copy number alterations (CNA) was observed from diagnosis to first relapse. Evolution from an ancestral clone was the main pattern of clonal evolution. Relapse samples were extremely heterogeneous regarding CNA frequencies. However, CDKN2A/B, PAX5, ETV6, ATM, IKZF1, VPREB1, and TP53 deletions and duplications of 1q, 8q, 17q, 21, X/Y PAR1, and Xp were frequently detected at relapse. Duplications of genes involved in cell proliferation, drug resistance and stem cell homeostasis regulation, as well as deletions of KDM6A and STAG2 genes emerged as specific alterations at relapse. Genomics of relapsed adult B-cell precursor ALL is highly heterogeneous, although some recurrent lesions involved in essential pathways deregulation were frequently observed. Selective and simultaneous targeting of these deregulated pathways may improve the results of current salvage therapies. © 2017 Wiley Periodicals, Inc.

Detection of circulating ESR1 mutations is associated with acquired resistance to aromatase inhibitor (AI) in metastatic breast cancer. Until now, the presence of circulating ESR1 mutations at the end of adjuvant treatment by AI in early breast cancer had never been clearly established. In this context, the aim of the present study was to evaluate the circulating ESR1 mutation frequency at the end of adjuvant treatment and after relapse. This monocentric retrospective study was based on available stored plasmas and included all early breast cancer patients who completed at least 2 years of AI adjuvant treatment and experienced a documented relapse after the end of their treatment. Circulating ESR1 mutations (D538G, Y537S/N/C) were assessed by droplet digital PCR in plasma samples taken at the end of adjuvant treatment, at time of relapse and at time of progression under first line metastatic treatment. A total of 42 patients were included, with a median adjuvant AI exposure of 60 months (range 41-85). No circulating ESR1 mutation was detectable at the end of AI adjuvant therapy. At first relapse, 5.3% of the patients (2/38) had a detectable circulating ESR1 mutation. At time of progression on first-line metastatic treatment, 33% of the patients (7/21) under AI had a detectable circulating ESR1 mutation compared to none of the patients under chemotherapy (0/10). The two patients with a detectable ESR1 mutation at relapse were treated by AI and had an increase of their variant allele fraction at time of progression on first-line metastatic treatment. Circulating ESR1 mutation detection at the end of AI-based adjuvant treatment is not clinically useful. Circulating ESR1 mutation could be assessed as soon as first relapse to guide interventional studies.

Background Although electroconvulsive therapy (ECT) has been shown to be extremely effective for the acute treatment of major depression, it has never been systematically assessed as a strategy for relapse prevention. Objective To evaluate the comparative efficacy of continuation ECT (C-ECT) and the combination of lithium carbonate plus nortriptyline hydrochloride (C-Pharm) in the prevention of depressive relapse. Design Multisite, randomized, parallel design, 6-month trial performed from 1997 to 2004. Setting Five academic medical centers and their outpatient psychiatry clinics. Patients Two hundred one patients with Structured Clinical Interview for DSM-IV–diagnosed unipolar depression who had remitted with a course of bilateral ECT. Interventions Random assignment to 2 treatment groups receiving either C-ECT (10 treatments) or C-Pharm for 6 months. Main Outcome Measure Relapse of depression, compared between the C-ECT and C-Pharm groups. Results In the C-ECT group, 37.1% experienced disease relapse, 46.1% continued to have disease remission at the study end, and 16.8% dropped out of the study. In the C-Pharm group, 31.6% experienced disease relapse, 46.3% continued to have disease remission, and 22.1% dropped out of the study. Both Kaplan-Meier and Cox proportional hazards regression analyses indicated no statistically significant differences in overall survival curves and time to relapse for the groups. Mean±SD time to relapse for the C-ECT group was 9.1±7.0 weeks compared with 6.7±4.6 weeks for the C-Pharm group (P=.13). Both groups had relapse proportions significantly lower than a historical placebo control from a similarly designed study. Conclusions Both C-ECT and C-Pharm were shown to be superior to a historical placebo control, but both had limited efficacy, with more than half of patients either experiencing disease relapse or dropping out of the study. Even more effective strategies for relapse prevention in mood disorders are urgently needed. PMID:17146008

In this preliminary study we analysed the impact of ovarian stimulations and the different protocols used for in vitro fertilizations (IVF) on the clinical activity of multiple sclerosis (MS). By matching the databases on MS and IVF of the past 10 years at the university hospital of Nantes, six patients have been found and, for five of them MS relapse rate seemed to be increased in the three-month period following IVF as compared to the previous three months and to two other control periods of three months (P<0.05, Friedman test). The increased relapse rate mainly concerned patients treated by GnRH agonists but not the patients treated by GnRH antagonists. This preliminary work suggests a possible impact of the treatments used for IVF on MS relapse rate. Further studies are now underway to validate these results on a larger scale, by including all cases reported in France.

This study investigates the impact of social phobia on adherence to and outcomes 6 months following standard alcohol treatment and Alcoholics Anonymous (AA) group meetings among alcohol-dependent patients with and without social phobia. In a cohort study, 300 detoxified alcohol-dependent individuals in Porto Alegre, Brazil, were interviewed during, as well as 3 and 6 months after hospital detoxification. At both follow-up points, treatment adherence was low and relapse rates were high among patients with and without social phobia, and no significant differences were seen between the two groups of patients in relapse, adherence to AA, or adherence to psychotherapy. Findings from this sample suggest that although alcohol-dependent patients with social phobia showed a tendency for less adherence at AA and felt less integrated with their AA group, social phobia comorbidity was not a significant risk factor for alcohol use relapse or for nonadherence to AA or psychotherapy.

Relapses represent one of the main problems of schizophrenia management. This article reviews the clinical factors associated with schizophrenia relapse. A research of the last 22 years of literature data was performed. Two-hundred nineteen studies have been included. Three main groups of factors are related to relapse: factors associated with pharmacological treatment, add-on psychotherapeutic treatments and general risk factors. Overall, the absence of a maintenance therapy and treatment with first generation antipsychotics has been associated with higher risk of relapse. Further, psychotherapy add-on, particularly with cognitive behaviour therapy and psycho-education for both patients and relatives, has shown a good efficacy for reducing the relapse rate. Among general risk factors, some could be modified, such as the duration of untreated psychosis or the substance misuse, while others could not be modified as male gender or low pre-morbid level of functioning. Several classes of risk factors have been proved to be relevant in the risk of relapse. Thus, a careful assessment of the risk factors here identified should be performed in daily clinical practice in order to individualise the relapse risk for each patient and to provide a targeted treatment in high-risk subjects.

We describe the series of iterative steps used to develop a smoking relapse-prevention intervention customized to the needs of cancer patients. Informed by relevant literature and a series of preliminary studies, an educational tool (DVD) was developed to target the unique smoking relapse risk factors among cancer patients. Learner verification interviews were conducted with 10 cancer patients who recently quit smoking to elicit feedback and inform the development of the DVD. The DVD was then refined using iterative processes and feedback from the learner verification interviews. Major changes focused on visual appeal, and the inclusion of additional testimonials and graphics to increase comprehension of key points and further emphasize the message that the patient is in control of their ability to maintain their smoking abstinence. Together, these steps resulted in the creation of a DVD titled Surviving Smokefree®, which represents the first smoking relapse-prevention intervention for cancer patients. If found effective, the Surviving Smokefree® DVD is an easily disseminable and low-cost portable intervention which can assist cancer patients in maintaining smoking abstinence.

Patients with Major Depressive Disorder (MDD) often experience unexpected relapses, despite achieving remission. This study examines the utility of a single multidimensional measure that captures variance in patient-reported Depressive Symptom Severity, Functioning, and Quality of Life (QOL), in predicting MDD relapse. Complete data from remitted patients at the completion of 12 weeks of citalopram in the STAR*D study were used to calculate the Individual Burden of Illness index for Depression (IBI-D), and predict subsequent relapse at six (n=956), nine (n=778), and twelve months (n=479) using generalized linear models. Depressive Symptom Severity, Functioning, and QOL were all predictors of subsequent relapse. Using Akaike information criteria (AIC), the IBI-D provided a good model for relapse even when Depressive Symptom Severity, Functioning, and QOL were combined in a single model. Specifically, an increase of one in the IBI-D increased the odds ratio of relapse by 2.5 at 6 months (β=0.921 ± 0.194, z=4.76, p<2 × 10(-6)), by 2.84 at 9 months (β=1.045 ± 0.22, z=4.74, p<2.2 × 10(-6)), and by 4.1 at 12 months (β=1.41 ± 0.29, z=4.79, p<1.7 × 10(-6)). Self-report poses a risk to measurement precision. Using highly valid and reliable measures could mitigate this risk. The IBI-D requires time and effort for filling out the scales and index calculation. Technological solutions could help ease these burdens. The sample suffered from attrition. Separate analysis of dropouts would be helpful. Incorporating patient-reported outcomes of Functioning and QOL in addition to Depressive Symptom Severity in the IBI-D is useful in assessing the full burden of illness and in adequately predicting relapse, in MDD. © 2013 Elsevier B.V.

Cigarette smoking has been reported to alter relapse rate in patients with Graves' disease (GD). However, the predictive effect of smoking in GD patients after withdrawal of antithyroid drug treatment (ATDT) is still controversial. A prospective multicenter trial has previously identified smoking as an independent risk factor for relapse. Based on this study, the present paper gives a more detailed analysis of the impact of smoking on the long-term course of GD after ATDT withdrawal. To this end, 86 smokers and 177 non-smokers were followed during two years after ATDT cessation. At the end of ATDT (visit 1) and four weeks later (visit 2) smokers had significant higher TSH receptor antibody (TRAb) levels than non-smokers (10.0 IU/L+/-1.6; mean+/-SEM vs. 6.4 IU/L+/-0.9; 11.0 IU/L+/-1.8 vs. 6.8 IU/L+/-0.8, p < 0.01, respectively). During follow-up, Kaplan Meier analysis showed a significantly higher relapse rate in smokers than non-smokers. A subset of GD patients with TRAb levels >10 IU/L had the highest risk to develop relapse during follow-up. Among them, smokers more often relapsed than non-smokers irrespective of TRAb levels, p < 0.01. Thus, in smokers with TRAb levels > or =10 IU/L the predictive values of a positive and negative test for relapse was 68% and 73%, respectively (specificity 95%). In conclusion, we identified two effects by which smoking alters the course of GD. First, smoking is implicated to elevate TRAb levels and therefore increase the risk for relapse during follow-up. Second, smoking is an independent risk factor to worsen the clinical course of both, GD patients with low and high immunological risk to experience relapse after a successful outcome of ATDT. Thus, our data suggest that smoking has modifying immunological consequences and an adverse impact on the course of GD after withdrawal of ATDT. Therefore, patients should be encouraged to stop smoking.

Impulsivity is one of the causes of relapse that can affect treatment outcomes. Studies have shown that addiction treatments can reduce impulsivity in drug-dependent individuals. Studies also have suggested that mindfulness is associated with impulsivity. However, no study has investigated the effectiveness of the mindfulness-based intervention on impulsivity in opioid-dependent individuals. This study aimed to compare the effectiveness of mindfulness-based relapse prevention (MBRP) with treatment as usual (TAU) in terms of impulsivity and relapse for methadone-treated patients. The present randomized controlled clinical trial was performed in Kashan, Iran, in 2015. The study population was opioid-dependent patients referred to Maintenance Treatment Centers. Seventy patients were selected by random sampling and were assigned in two groups (MBRP and TAU) randomly. The participants of two groups filled out Barratt impulsivity scale (BIS-11) as a pre-test and 8 weeks later as post-test and 2 months later as a follow-up. Both groups received methadone-therapy. The MBRP group received 8 sessions of group therapy, while the control group did not receive any group psychotherapy session. Finally, data from 60 patients were analyzed statistically. The MBRP group had decreased impulsivity significantly (P < 0.001). The mean impulsivity score was 74.76 ± 4.72 before intervention that was significantly decreased to 57.66 ± 3.73 and 58.86 ± 3.57 after the intervention and follow-up (P < 0.001), respectively. In addition, significant differences were observed between MBRP and TAU groups for relapse frequency (P < 0.050). This study showed that MBRP compared to TAU can decrease the mean impulsivity score in opioid-dependent and reduce relapse probability. These findings suggest that MBRP is useful for opioid-dependent individuals with high-level impulsivity, and relapse prevention.

To elucidate the impact of minimal residual disease (MRD) after allogeneic transplantation, the Acute Lymphoblastic Leukemia Berlin-Frankfurt-Münster Stem Cell Transplantation Group (ALL-BFM-SCT) conducted a prospective clinical trial. In the ALL-BFM-SCT 2003 trial, MRD was assessed in the bone marrow at days +30, +60, +90, +180, and +365 after transplantation in 113 patients with relapsed disease. Standardized quantification of MRD was performed according to the guidelines of the Euro-MRD Group. All patients showed a 3-year probability of event-free survival (pEFS) of 55%. The cumulative incidence rates of relapse and treatment-related mortality were 32% and 12%, respectively. The pEFS was 60% for patients who received their transplantations in second complete remission, 50% for patients in ≥ third complete remission, and 0% for patients not in remission (P = .015). At all time points, the level of MRD was inversely correlated with event-free survival (EFS; P < .004) and positively correlated with the cumulative incidence of relapse (P < .01). A multivariable Cox model was fitted for each time point, which showed that MRD ≥ 10(-4) leukemic cells was consistently correlated with inferior EFS (P < .003). The accuracy of MRD measurements in predicting relapse was investigated with time-dependent receiver operating curves at days +30, +60, +90, and +180. From day +60 onward, the discriminatory power of MRD detection to predict the probability of relapse after 1, 3, 6, and 9 months was more than 96%, more than 87%, more than 71%, and more than 61%, respectively. MRD after transplantation was a reliable marker for predicting impending relapses and could thus serve as the basis for pre-emptive therapy. © 2015 by American Society of Clinical Oncology.

Technetium thyroid uptake (TTU) is not inhibited by antithyroid drugs (ATD) and reflects the degree of thyroid stimulation. We intended to predict the relapse rate from hyperthyroidism based on TTU measurement. Out of 44 initially enrolled subjects, 38 patients aged 41.6 ± 14.6 with Graves disease (duration: 84 ± 78 months) completed the study. TTU was performed with 40-second imaging of the neck and mediastinum 20 minutes after injection of 1 mCi technetium-99m pertechnetate. TTU was measured as the percentage of the count of activity accumulated in the thyroidal region minus the mediastinal background uptake to the count of 1 mCi technetium-99m under the same acquisition conditions. Then methimazole was stopped and patients were followed. The optimal TTU cutoff value for Graves relapse prediction was calculated using Youden's J statistic. Hyperthyroidism relapsed in 11 (28.9%) patients 122 ± 96 (range: 15-290) days post-ATD withdrawal. The subjects in remission were followed for 209 ± 81 days (range: 88-390). TTU was significantly higher in patients with forthcoming relapse (12.0 ± 8.0 vs. 3.9 ± 2.0, P = .007). The difference was significant after adjustment for age, sex, history of previous relapse, disease duration, and thyroid-stimulating hormone (TSH) levels before withdrawal. The area under the receiver operative characteristic (ROC) curve was 0.87. The optimal TTU cutoff value for classification of subjects with relapse and remission was 8.7 with sensitivity, specificity, and positive and negative predictive value of 73%, 100%, 100%, and 90%, respectively (odds ratio [OR] = 10.0; 95% confidence interval [CI]: 3.4-29.3). TTU evaluation in hyperthyroid patients receiving antithyroid medication is an accurate and practical method for predicting relapse after ATD withdrawal. ATD = antithyroid drugs RIU = radio-iodine uptake TSH = thyroid-stimulating hormone TSI = thyroid-stimulating immunoglobulin TTU = technetium thyroid uptake.

In the CLARITY (CLAdRIbine Tablets treating multiple sclerosis orallY) study, Cladribine Tablets significantly improved clinical and magnetic resonance imaging (MRI) outcomes (vs placebo) in patients with relapsing-remitting multiple sclerosis. Describe two clinically relevant definitions for patients with high disease activity (HDA) at baseline of the CLARITY study (utility verified in patients receiving placebo) and assess the treatment effects of Cladribine Tablets 3.5 mg/kg compared with the overall study population. Outcomes of patients randomised to Cladribine Tablets 3.5 mg/kg or placebo were analysed for subgroups using HDA definitions based on high relapse activity (HRA; patients with ⩾2 relapses during the year prior to study entry, whether on DMD treatment or not) or HRA plus disease activity on treatment (HRA + DAT; patients with ⩾2 relapses during the year prior to study entry, whether on DMD treatment or not, PLUS patients with ⩾1 relapse during the year prior to study entry while on therapy with other DMDs and ⩾1 T1 Gd+ or ⩾9 T2 lesions). In the overall population, Cladribine Tablets 3.5 mg/kg reduced the risk of 6-month-confirmed Expanded Disability Status Scale (EDSS) worsening by 47% vs placebo. A risk reduction of 82% vs placebo was seen in both the HRA and HRA + DAT subgroups (vs 19% for non-HRA and 18% for non-HRA + DAT), indicating greater responsiveness to Cladribine Tablets 3.5 mg/kg in patients with HDA. There were consistent results for other efficacy endpoints. The safety profile in HDA patients was consistent with the overall CLARITY population. Patients with HDA showed clinical and MRI responses to Cladribine Tablets 3.5 mg/kg that were generally better than, or at least comparable with, the outcomes seen in the overall CLARITY population.

Background Rituximab has been used in antineutrophil cytoplasmic antibody (ANCA)-associated vasculitis (AAV) since 2003. Our objective was to describe outcomes and adverse events following rituximab since that time in an inception cohort. Methods Patients with AAV (diagnosed 1991–2012) who received rituximab (n = 120) were evaluated and incidence per person-year (PPY) with 95% confidence interval was calculated for relapse and infections. Time to remission and relapse by number of rituximab infusions given per treatment course (≤2 versus >2) and by ever having been exposed to cyclophosphamide were compared using Kaplan–Meier curves. Rituximab-treated patients were characterized in comparison with AAV patients treated with cyclophosphamide but not exposed to rituximab (n = 351) using Fisher's exact or rank tests. Results Rituximab resulted in 86% achieving remission and 41% having a subsequent relapse in a median of 19 months (range 9–29). Time to remission and relapse were similar between rituximab infusion courses (≤2 versus >2; remission P = 0.86 and relapse P = 0.78, respectively). Incidence of relapse was 0.22 PPY (0.14, 0.31) and of severe infection was 0.12 PPY (0.08, 0.24). Time to relapse was shorter in those never exposed to cyclophosphamide (n = 20): 50% by 8 months versus 50% by 24 and 30 months for those with prior or concurrent exposure to cyclophosphamide (n = 100). Compared with those who never received rituximab, rituximab-treated patients were younger (P < 0.001), more likely to have granulomatosis with polyangiitis (P = 0.001) and had more upper airway (P = 0.01) and less kidney involvement (P = 0.007). Conclusions Rituximab is beneficial when prescribed outside of a trial setting. Response to treatment and relapse is similar regardless of infusion number. Rituximab without cyclophosphamide may result in a shorter time to relapse supporting combination of these therapies. PMID:25805743

Wilms' tumor gene 1 (WT1) expression is a well-known predictor for relapse in acute myeloid leukemia. We monitored WT1 decrement along the treatment course to identify its significant role as a marker for residual disease in acute promyelocytic leukemia (APL) and tried to suggest its significance for relapse prediction. In this single center retrospective study, we serially measured PML-RARa and WT1 expression from 117 APL patients at diagnosis, at post-induction and post-consolidation chemotherapies, and at every 3 months after starting maintenance therapy. All 117 patients were in molecular remission after treatment of at least 2 consolidation chemotherapies. We used WT1 ProfileQuant™ kit (Ipsogen) for WT1 monitoring. High WT1 expression (>120 copies/10 4 ABL1) after consolidation and at early period (3 months) after maintenance therapy significantly predicted subsequent relapse. All paired PML-RARa RQ-PCR were not detected except for one sample with early relapse. Patients with high WT1 expression at 3 months after maintenance therapy (n = 40) showed a significantly higher relapse rate (30.5 vs. 6.9%, P < 0.001) and inferior disease free survival (62.8 vs. 91.4%, P < 0.001). Multivariate analysis revealed that high peak leukocyte counts at diagnosis (HR = 6.4, P < 0.001) and high WT1 expression at 3 months after maintenance therapy (HR = 7.1, P < 0.001) were significant factors for prediction of relapse. Our data showed high post-remission WT1 expression was a reliable marker for prediction of subsequent molecular relapse in APL. In this high-risk group, early intervention with ATRA ± ATO, anti-CD33 antibody therapy, and WT1-specific therapy may be used for relapse prevention.

In relapsed or refractory non-Hodgkin lymphoma (NHL), allogeneic hematopoietic stem cell transplantation (allo-HSCT) provides graft-versus-lymphoma activity resulting in fewer incidences of relapse. However, therapy-related mortality (TRM) remains an important challenge. We attempted to introduce our reduced-intensity conditioning (RIC) regimen. From 2007 to 2013, we treated 28 relapsed or refractory NHLs with allo-HSCT. All were pre-conditioned with fludarabine [FLU, 180 mg/body surface area (BSA)/6 days] and melphalan (MEL, 70 mg/BSA/1 day); 25 (all but 3) were additionally treated with total body irradiation (TBI, 800 cGy/4Fx/2 days). Peripheral blood stem cells were collected from matched siblings (n = 10) or suitably matched unrelated (n = 18) donors. There were eight diffuse large B-cell lymphomas, seven peripheral T-cell lymphoma not otherwise specified, give lymphoblastic lymphomas, two mantle cell lymphomas, and six various other lymphomas. Of these patients, 10 relapsed after auto-HSCT, 5 relapsed after chemotherapy, and 13 were refractory lymphomas. After allo-HSCT, complete remission was achieved in 22 (78.5%) patients. After a median follow-up of 24.8 months, 3-year overall survival and disease-free survival were 62.4 and 59.2% and the 3-year TRM and relapse incidence were 14.9 and 28.6% respectively. Acute and chronic graft-versus-host diseases (GVHDs) were identified in 17 (≥Grade II in 12 patients) and 18 patients respectively, and the group with chronic GVHD showed favourable survival outcomes. In relapsed or refractory NHL, RIC-allo-HSCT using FLU + MEL + 800 cGy TBI showed favourable survival outcomes with acceptable TRM and relapse incidence. Copyright © 2015 John Wiley & Sons, Ltd.

Mild-to-moderate ulcerative colitis: your role in patient compliance and health care costs.

Ulcerative colitis (UC) is a chronic relapsing disease necessitating lifelong treatment. Most patients present with mild-to-moderate disease characterized by alternating periods of remission and clinical relapse. Continued disease progression and relapse of UC over time are associated with an increased risk of colorectal cancer (CRC). To discuss the latest treatment options for mild-to-moderate UC, to review the current data involving the economics of UC, and to demonstrate the relationship between treatment adherence, clinical relapse, inflammation severity, CRC risk, and treatment outcomes. One of the main goals of therapy in UC is to induce and maintain a long-lasting remission of disease to reduce or avoid the high personal and financial costs of relapse. In recent studies, researchers have demonstrated a link between increased colonic inflammation and CRC risk, highlighting the importance of preventing relapse, which can lead to costly surgical procedures and hospital stays and thus increase the cost of treatment 2- to 20-fold. The risk of disease relapse is affected by several factors, of which the most prominent is nonadherence to maintenance therapy. Nonadherence to therapy can be associated with several other factors, including forgetfulness, male sex, complicated dosing regimens, treatment delivery methods (oral vs. rectal), and pill burden. In the treatment of mild-to-moderate UC, 5-aminosalicyclic acid (5-ASA) is the standard first-line therapy and the treatment of choice for maintaining remission of disease. Novel formulations of 5-ASA and newly devised high-dose 5-ASA regimens offer more options for the treatment of UC and thus may lead to improved treatment adherence, longer remission, and improved patient well-being. Periods of remission during UC treatment must be aggressively maintained to prevent relapse and decrease the risk of an unfavorable outcome. By controlling the risks and conditions that lead to therapeutic nonadherence and relapse among patients with UC, clinicians can increase the likelihood of long-term remission and ensure favorable long-term outcomes.

The risk of acute graft-versus-host disease (GVHD) after HLA-matched sibling bone marrow (BM) transplantation is lower in Japanese than in Caucasian patients. However, race may have differential effect on GVHD dependent on the graft source. North American Caucasian and Japanese patients receiving their first allogeneic BM or peripheral blood stem cell (PBSC) transplantations from an HLA-matched sibling for leukemia were eligible. BM was used in 13% and 53% of Caucasian and Japanese patients, respectively. In multivariate analysis, the interaction term between race and graft source was not significant in any of the models, indicating that graft source does not affect the impact of race on outcomes. The risk of grades III–IV acute GVHD was significantly lower in Japanese than in Caucasian patients (hazard ratio (HR) 0.74, 95% confidence interval (CI) 0.57–0.96), which resulted in lower risk of non-relapse mortality in Japanese patients (HR 0.69, 95% CI 0.54–0.89). The risk of relapse was also lower in this group. Lower risk of non-relapse mortality and relapse resulted in lower overall mortality rates among Japanese patients. In conclusion, irrespective of graft source, the risk of severe acute GVHD is lower in Japanese patients, which results in lower risk of non-relapse mortality. PMID:26762681

Relapse in psychiatric disorders is highly distressing, costly and engenders burn-out syndrome among mental-health workers. To study the socio-economic factors associated with relapse in individual admitted with psychiatric disorders and the pattern of socio-economic impact of relapse in those groups. A cross-sectional survey of all relapsed patients without cognitive deficit admitted into the federal Neuro-Psychiatric Hospital, Lagos, Nigeria between June and October 2007 was conducted using a self-validated Structured Interview Schedule (Relapse Socio-economic Impact Interview Schedule) and Key Informant Interview Guide. Secondary data were elicited from the patient folders, case notes, ward admission registers and nominal rolls. Data were summarised using mean, standard deviation, frequency and percentiles. Pearson's moment correlation coefficient was used to test the association among variables. The Mann-Whitney U-test was used to compare the pre-morbid and the post-morbid states. This study involved 102 respondents. Their mean age was 36.5 ± 9.8 years, mainly of male gender (72.5%) suffering from schizophrenic disorder (37.8%). Relapse and re-admission ranged between 2 and 12. Unemployment rate, marital separation and divorce increased more than 5-fold from pre-morbid to morbid states. Few (4.9%) could still settle their hospital/drug bills on their own, while most (95.1%) depended on family, philanthropist and government/waivers to pay for their bills. Their social relationships were negatively influenced with most of them expressing social isolation and low quality of life. There were significant relationships (P<0.05) between age, sex, number of relapses, number of admissions, pre-morbid marital status, morbid state marital status, pre-morbid state occupational status and morbid state occupational status. There was significant change (P= 0.00) in the quality of life, societal integration/acceptability, economic status, employment status and marital status of the respondents between the pre-morbid and post-morbid periods. The illness significantly affected the emotional status of the participants. Relapse and readmission in psychiatric patients have a negative impact on socio-economic well-being of patients, family and the society. Efforts should be taken to provide early interventions.

Relationship of expressed emotion with relapse of schizophrenia patients in Kelantan.

The families of 83 schizophrenic patients were studied to find out the level of expressed emotion in them leading to the relapse of these patients. The patients were having more than two episodes of schizophrenia (DSM-III-R). The most salient finding was the virtual absence of high level of expressed emotion as the cause of relapse. It was found that the majority of the families (72.3%) had low expressed emotion while only 25.3% had high expressed emotion and only 2.4% families were equivocal in this respect. This finding is in contrast with various other findings in this area. The most likely explanation for this disagreement is the cultural differences between Malaysian patients and Western patients.

No study has examined the possibility to perform an organ sparing strategy in older patients with penile carcinoma, and amputation is frequently proposed. We report our experience of interstitial brachytherapy for the conservative treatment of penile carcinoma confined to the glans in patients aged of 70years and more. A total of 55 patients candidates to conservative brachytherapy were identified. Median age was 73.8years (range: 70-95years). Patients underwent a circumcision then 3-4weeks later, an interstitial brachytherapy was delivered, median dose of 65Gy (range 55-74Gy). Salvage surgery was discussed in patients with histological confirmation of residual/relapsed tumor. With median follow-up of 9.0years, eight patients (14.5%) experienced a relapse, including five patients with local relapse. Three patients with local relapse only underwent salvage penile surgery, including two partial glansectomies and one total penectomy, and were in second complete remission at last follow-up. Among 55 patients analyzed for late side effects, seven patients (13.0%) presented pain or ulceration, 12 (22.2%) experienced urethral or meatal stenosis requiring at least one dilatation, two patients (3.7%) experienced both ulcerations and urethral complication. Three patients (5.5%) needed partial glansectomy for focal necrosis. At five years, estimated overall survival rate was 74.5% (95%CI: 62.0-87.0%) and local relapse free rate was 91.0% (95%CI: 82.6-99.4%). Brachytherapy is feasible in selected older patients with penile carcinoma, with efficacy and toxicity rates comparable to that of other series in younger patients. Copyright © 2017 Elsevier Inc.

There are limited effective therapies for most patients with relapsed diffuse large B-cell lymphoma (DLBCL). We conducted a phase II trial of the multi-targeted vascular endothelial growth factor receptor (VEGFR) kinase inhibitor, sunitinib, 37.5 mg given orally once daily in adult patients with relapsed or refractory DLBCL. Of 19 enrolled patients, 17 eligible patients were evaluable for toxicity and 15 for response. No objective responses were seen and nine patients achieved stable disease (median duration 3.4 months). As a result, the study was closed at the end of the first stage. Grades 3-4 neutropenia and thrombocytopenia were observed in 29% and 35%, respectively. There was no relationship between change in circulating endothelial cell numbers (CECs) and bidimensional tumor burden over time. Despite some activity in solid tumors, sunitinib showed no evidence of response in relapsed/refractory DLBCL and had greater than expected hematologic toxicity.

All responders to induction therapy were randomized to treatment with 2400 rad of cranial irradiation plus intrathecal methotrexate or to treatment with intermediate-dose methotrexate plus intrathecal methotrexate, as prophylaxis for involvement of the central nervous system and other sanctuary areas. Complete responders were stratified into either standard-risk or increased-risk groups on the basis of age and white-cell count at presentation. Among patients with standard risk, hematologic relapses occurred in 9 of 117 given methotrexate and 24 ofmore » 120 given irradiation. The rate of central-nervous-system relapse was higher in the methotrexate group (23 of 117) than in the irradiation group. Among patients with increased risk, radiation offered greater protection to the central nervous system than methotrexate; there was no difference in the rate of hematologic relapse. Methotrexate offered better protection against systemic relapse in standard-risk patients and better protection against testicular relapse overall, but it offered less protection against relapses in the central nervous system than cranial irradiation.« less

Allogeneic haematopoietic stem-cell transplantation remains the only curative treatment for relapsed/refractory acute myeloid leukaemia (AML) and high-risk myelodysplasia but has previously been limited to patients who achieve remission before transplant. New sequential approaches employing T-cell depleted transplantation directly after chemotherapy show promise but are burdened by viral infection and require donor lymphocyte infusions (DLI) to augment donor chimerism and graft-versus-leukaemia effects. T-replete transplantation in sequential approaches could reduce both viral infection and DLI usage. We therefore performed a single-arm prospective Phase II clinical trial of sequential chemotherapy and T-replete transplantation using reduced-intensity conditioning without planned DLI. The primary endpoint was overall survival. Forty-seven patients with relapsed/refractory AML or high-risk myelodysplasia were enrolled; 43 proceeded to transplantation. High levels of donor chimerism were achieved spontaneously with no DLI. Overall survival of transplanted patients was 45% and 33% at 1 and 3 years. Only one patient developed cytomegalovirus disease. Cumulative incidences of treatment-related mortality and relapse were 35% and 20% at 1 year. Patients with relapsed AML and myelodysplasia had the most favourable outcomes. Late-onset graft-versus-host disease protected against relapse. In conclusion, a T-replete sequential transplantation using reduced-intensity conditioning is feasible for relapsed/refractory AML and myelodysplasia and can deliver graft-versus-leukaemia effects without DLI. © 2017 John Wiley & Sons Ltd.

Substance users approach a treatment facility for a variety of reasons as well as avoid or delay in help seeking due to perceived fears with treatment facilities. Sometimes these factors might be associated with treatment outcomes. We studied the relationship of reasons and fears of treatment seeking with treatment outcome in substance users. One hundred subjects, attending the Drug Deaddiction and Treatment Centre, PGIMER, were prospectively recruited by purposive sampling. A semistructured proforma was used to gather sociodemographic and clinical data. Reasons of help-seeking and fear questionnaire, social support scale, and PGI locus of control scale were then applied. Followup data were available for 69 patients, which were classified into good or poor outcome based on relapse status. At 6 months followup, 22 patients had relapsed, while 47 patients did not relapse. A higher degree of dysfunction due to substance at baseline was associated with relapsed status at followup. Parents or guardians coming to know about resuming substance and being unemployed for a long time were the reasons associated with relapsed status, while needing to consult a doctor immediately was significantly related to abstinent status at followup. Fear of not being able to meet substance using friends was associated with a poorer outcome in the form of relapse. Reasons for treatment seeking as well as fears related to treatment have significant implications on the clinical outcome of substance abusing patients. Addressing these could help in better patient outcomes.

Relapsed neuroblastomas show frequent RAS-MAPK pathway mutations | Office of Cancer Genomics

Cancer.gov

The majority of patients with neuroblastoma have tumors that initially respond to chemotherapy, but a large proportion will experience therapy-resistant relapses. The molecular basis of this aggressive phenotype is unknown. Whole-genome sequencing of 23 paired diagnostic and relapse neuroblastomas showed clonal evolution from the diagnostic tumor, with a median of 29 somatic mutations unique to the relapse sample. Eighteen of the 23 relapse tumors (78%) showed mutations predicted to activate the RAS-MAPK pathway.

Background To determine the 5-year recurrence-free survival in patients with high-risk prostate cancer after neoadjuvant combination chemotherapy followed by surgery. Secondary endpoints included safety, pathologic effects of chemotherapy and predictors of disease recurrence. Patients and Methods Fifty seven patients were enrolled in a Phase I/II study of weekly docetaxel 35 mg/m2 and escalating mitoxantrone to 4 mg/m2 prior to prostatectomy. Patients were treated with 16 weeks of chemotherapy administered weekly on a 3 of every 4 week schedule. A tissue micro-array, constructed from the prostatectomy specimens served to facilitate the exploratory evaluation of biomarkers. The primary end point was relapse-free survival. Relapse was defined as a confirmed serum prostate-specific antigen (PSA) > 0.4 ng/ml. Results Of the 57 patients, 54 received 4 cycles of docetaxel and mitoxantrone prior to radical prostatectomy. Grade 4 toxicities were limited to leucopenia, neutropenia and hyperglycemia. Serum testosterone levels remained stable after chemotherapy. Negative surgical margins were attained in 67% of cases. Lymph node involvement was detected in 18.5% of cases. With a median follow-up of 63 months, 27 of 57 (47.4%) patients recurred. The Kaplan-Meier relapse-free survival at 2 years was 65.5% (95%CI 53.0% to 78.0%) and 49.8% at 5 years (95%CI 35.5% to 64.1%). Pretreatment serum PSA, lymph node involvement, and post-chemotherapy tissue VEGF expression were independent predictors of early relapse. Conclusions Preoperative chemotherapy with docetaxel and mitoxantrone is feasible. Approximately half of the high risk patients remain relapse free at 5 years and clinical and molecular predictors of early relapse were identified. PMID:20143429

Rimner, Andreas; Lovie, Shona; Hsu, Meier

Purpose: We report the long-term results of integrated accelerated involved field radiation therapy (IFRT) followed by total lymphoid irradiation (TLI) as part of the high-dose salvage regimen followed by autologous bone marrow transplantation or autologous stem cell transplantation in patients with relapsed or refractory Hodgkin lymphoma (HL). Methods and Materials: From November 1985 to July 2008, 186 previously unirradiated patients with relapsed or refractory HL underwent salvage therapy on 4 consecutive institutional review board–approved protocols. All patients had biopsy-proven primary refractory or relapsed HL. After standard-dose salvage chemotherapy (SC), accelerated IFRT (18-20 Gy) was given to relapsed or refractory sites, followedmore » by TLI (15-18 Gy) and high-dose chemotherapy. Overall survival (OS) and event-free survival (EFS) were analyzed by Cox analysis and disease-specific survival (DSS) by competing-risk regression. Results: With a median follow-up period of 57 months among survivors, 5- and 10-year OS rates were 68% and 56%, respectively; 5- and 10-year EFS rates were 62% and 56%, respectively; and 5- and 10-year cumulative incidences of HL-related deaths were 21% and 29%, respectively. On multivariate analysis, complete response to SC was independently associated with improved OS and EFS. Primary refractory disease and extranodal disease were independently associated with poor DSS. Eight patients had grade 3 or higher cardiac toxicity, with 3 deaths. Second malignancies developed in 10 patients, 5 of whom died. Conclusions: Accelerated IFRT followed by TLI and high-dose chemotherapy is an effective, feasible, and safe salvage strategy for patients with relapsed or refractory HL with excellent long-term OS, EFS, and DSS. Complete response to SC is the most important prognostic factor.« less

Background Autologous stem cell transplantation (ASCT) is the standard treatment for patients with relapsed diffuse large B-cell lymphoma (DLBCL) or transformed indolent lymphoma (TIL). The treatment is mainly considered for younger patients still available for the work market. In this study, social outcomes after ASCT in terms of return to work (RTW) are described. Patients and methods Information from national administrative registers was combined with clinical information on patients, who received ASCT for relapse of DLBCL or TIL between 2000 and 2012. A total of 164 patients were followed until RTW, disability or old-age pension, death, or December 31, 2015, whichever came first. A total of 205 patients were followed with disability pension as the event of interest. Cox models were used to determine cause-specific hazards. Results During follow-up, 82 (50%) patients returned to work. The rate of returning to work in the first year following ASCT was decreased for patients being on sick leave at the time of relapse (hazard ratio [HR] 0.3 [0.2;0.5]) and increased for patients aged ≥55 years (HR 1.9 [1.1;3.3]). In all, 56 (27%) patients were granted disability pension. Being on sick leave at the time of relapse was positively associated with receiving a disability pension in the first 2 years after ASCT (HR 3.7 [1.8;7.7]). Conclusion Patients on sick leave at the time of relapse have a poorer prognosis regarding RTW and have a higher rate of disability pension. Furthermore, patients >55 are more likely to RTW compared to younger patients. These results indicate an unmet need for focused social rehabilitation. PMID:28652814

Tyrosine kinase inhibitors (TKIs) are the cornerstones of treatment for patients with chronic myeloid leukaemia (CML). In recent years, several studies were conducted to evaluate the safety of TKIs discontinuation. We performed a systematic review of the literature to determine the incidence of CML relapse, to identify possible factors relapse rates and to evaluate the long-term safety in CML patients with stable undetectable BCR-ABL transcript level who discontinued TKIs. Studies evaluating TKIs discontinuation in CML patients with undetectable BCR-ABL transcript level were identified by electronic search of MEDLINE and EMBASE database until May 2015. Weighted mean proportion and 95% confidence intervals (CIs) of CML relapse was calculated using a fixed-effects and a random-effects model. Statistical heterogeneity was evaluated using the I 2 statistic. Fifteen cohort studies, for a total of 509 patients, were included. Nine studies were at low-risk of bias. All 15 studies included only patients on imatinib. Overall weighted mean molecular relapse rate of CML was 51% (95% CI 44-58%; I 2  = 55). Weighted mean molecular relapse rate at 6-month follow-up was 41% (95% CI 32-51%; I 2  = 78). Eighty percent of molecular relapses occurred in the first 6 months. All 509 patients were alive at 2-year follow-up and only one patient (0.8%, 95% CI 0.2-1.8%; I 2  = 0) has progressed to a blastic crisis. Our findings suggest that imatinib discontinuation is feasible for the majority of CML patients with stable undetectable BCR-ABL transcript level. Approximately 50% of patients remain therapy-free after imatinib discontinuation. Restarting TKIs therapy was followed by a very high rate of molecular response, with no deaths 2 years after discontinuation. Copyright © 2017 Elsevier Ltd. All rights reserved.

Despite recent progress in the management of chronic bacterial prostatitis (CBP), many cases relapse. Increased drug resistance patterns of responsible bacteria have been proposed as the most probable causative factor. Driven by the limited number of previous studies addressing this topic, we aimed to study whether antibiotic resistance increases in patients with CBP when relapse occurs. A secondary aim of this study was to determine the resistance patterns of responsible bacteria from patients with CBP. The study material consisted of bacterial isolates from urine and/or prostatic secretions obtained from patients with CBP. Bacterial identification was performed by using the Vitek 2 Compact system and susceptibility testing was performed by disc diffusion and/or the Vitek 2 system. Interpretation of susceptibility results was based on Clinical and Laboratory Standards Institute guidelines. A total of 253 samples from patients diagnosed with CBP for the first time (group A) and 137 samples from relapsing patients with a history of CBP and previous antibiotic treatment (group B) were analyzed. A significant reduction in bacterial resistance to the less used antibiotics (TMP-SMX, tetracyclines, aminoglycosides, penicillins, and macrolides) was noted. An increase in resistance to quinolones of many bacteria that cause CBP was also noted with the increase in resistance of enterococcus strains being alarming. Comparison of the resistance profile of CBP-responsible bacteria between samples from first-time-diagnosed patients and samples from relapsing patients revealed notable differences that could be attributed to previous antibiotic treatment.

In this prospective study 60 patients of median age 46 (range 5–60) years, with acute myeloid leukemia (AML; n=44), acute lymphoblastic leukemia (ALL; n=3), or myelodysplastic syndrome (MDS; n=13) were conditioned for allogeneic hematopoietic cell transplantation with a treosulfan/fludarabine combination. Most patients were considered at high risk for relapse or non-relapse mortality (NRM). Patients received intravenous treosulfan, 12 g/m2/day (n=5) or 14 g/m2/day (n=55) on days -6 to -4, and fludarabine (30 mg/m2/day) on days -6 to -2, followed by infusion of marrow (n=7) or peripheral blood stem cells (n=53) from HLA-identical siblings (n=30) or unrelated donors (n=30). All patients engrafted. NRM was 5% at day 100, and 8% at 2 years. With a median follow-up of 22 months, the 2-year relapse-free survival for all patients was 58% and 88% for patients without high risk cytogenetics. The 2-year cumulative incidence of relapse was 33% (15% for patients with MDS, 34% for AML in first remission, 50% for AML or ALL beyond first remission and 63% for AML in refractory relapse). Thus, a treosulfan/fludarabine regimen was well tolerated and yielded encouraging survival and disease control with minimal NRM. Further trials are warranted to compare treosulfan/fludarabine to other widely used regimens, and to study the impact of using this regimen in more narrowly defined groups of patients. PMID:20685259

Background Targeted therapy, using biomarkers to assess disease activity in ulcerative colitis (UC), has been proposed. Objective The objective of this study was to evaluate whether pharmacological intervention guided by fecal calprotectin (FC) prolongs remission in patients with UC. Methods A total of 91 adults with UC in remission were randomized to an intervention group or a control group. Analysis of FC was performed monthly, during 18 months. A FC value of 300 µg/g was set as the cut-off for intervention, which was a dose escalation of the oral 5-aminosalicylate (5-ASA) agent. The primary study end-point was the number of patients to have relapsed by month 18. Results There were relapses in 18 (35.3%) and 20 (50.0%) patients in the intervention and the control groups, respectively (p = 0.23); and 28 (54.9%) patients in the intervention group and 28 (70.0%) patients in the control group had a FC > 300 µg/g, of which 8 (28.6%) and 16 (57.1%) relapsed, respectively (p < 0.05). Conclusion Active intervention significantly reduced relapse rates, although no significant difference was reached between the groups overall. Thus, FC-levels might be used to identify patients with UC at risk for a flare, and a dose escalation of their 5-ASA agent is a therapeutic option for these patients. PMID:25653861

The prevention of relapse in recurrent depression is considered a central aim in cognitive-behavioral therapy, given the high risk of relapse. In this study, patients with recurrent major depressive disorder (currently remitted) received 16 sessions of Maintenance Cognitive-Behavioral Therapy (M-CBT) over a period of 8 months, in order to prevent relapse. Therapist adherence and competence, as well as the therapeutic alliance, were investigated as predictors for reducing the risk of recurrence in depression. Videotapes of 80 participants were analyzed in order to evaluate therapist adherence and competence. Additionally, the therapeutic alliance was assessed by questionnaire. No associations were found between therapist adherence or competence, and the risk of relapse 1 year after treatment. By contrast, the therapeutic alliance was a significant predictor of the time to relapse. Moreover, we found that the number of previous depressive episodes (≥ 5 vs. ≤ 4) was a significant moderator variable. This indicates that the alliance-outcome relationship was particularly important when patients with five or more previous depressive episodes were taken into account, in comparison to patients with four or fewer episodes. For the psychotherapeutic treatment of recurrent depression and the prevention of relapse, sufficient attention should be paid to the therapeutic alliance. Copyright © 2013 Elsevier Ireland Ltd.

In childhood acute lymphoblastic leukaemia (ALL), central nervous system (CNS) involvement is rare at diagnosis (1-4%), but more frequent at relapse (~30%). Because of the significant late sequelae of CNS treatment, early identification of patients at risk of CNS relapse is crucial. Using microarray-analysis, we discovered multiple differentially expressed genes between B-cell precursor (BCP) ALL cells in bone marrow (BM) and BCP-ALL cells in cerebrospinal fluid (CSF) at the time of isolated CNS relapse. After confirmation by real-time quantitative polymerase chain reaction, selected genes (including SCD and SPP1) were validated at the protein level by flowcytometric analysis of BCP-ALL cells in CSF. Further flowcytometric validation showed that a subpopulation of BCP-ALL cells (>1%) with a 'CNS protein profile' (SCD positivity and increased SPP1 expression) was present in the BM at diagnosis in patients who later developed an isolated CNS relapse, whereas this subpopulation was <1% or absent in all other patients. These data indicate that the presence of a (small) subpopulation of BCP-ALL cells with a 'CNS protein profile' at diagnosis (particularly SCD-positivity) is associated with isolated CNS relapse. Such information can be used to design new diagnostic and treatment strategies that aim at prevention of CNS relapse with reduced toxicity. © 2015 John Wiley & Sons Ltd.

Background: Biomarkers predicting the risk of VL treatment failure and relapse in VL/HIV coinfected patients are needed. Nested within a two-site clinical trial in Ethiopia (2011-2015), we conducted an exploratory study to assess whether (1) levels of Leishmania antigenuria measured at VL diagnosis were associated with initial treatment failure and (2) levels of Leishmania antigenuria at the end of treatment (parasitologically-confirmed cure) were associated with subsequent relapse. Methods: Leishmania antigenuria at VL diagnosis and cure was determined using KAtex urine antigen test and graded as negative (0), weak/moderate (grade 1+/2+) or strongly-positive (3+). Logistic regression and Kaplan-Meier methods were used to assess the association between antigenuria and (1) initial treatment failure, and (2) relapse over the 12 months after cure, respectively. Results: The analysis to predict initial treatment failure included sixty-three coinfected adults [median age: 30 years interquartile range (IQR) 27-35], median CD4 count: 56 cells/μL (IQR 38-113). KAtex results at VL diagnosis were negative in 11 (17%), weak/moderate in 17 (27%) and strongly-positive in 35 (36%). Twenty (32%) patients had parasitologically-confirmed treatment failure, with a risk of failure of 9% (1/11) with KAtex-negative results, 0% (0/17) for KAtex 1+/2+ and 54% (19/35) for KAtex 3+ results. Compared to KAtex-negative patients, KAtex 3+ patients were at increased risk of treatment failure [odds ratio 11.9 (95% CI 1.4-103.0); P : 0.025]. Forty-four patients were included in the analysis to predict relapse [median age: 31 years (IQR 28-35), median CD4 count: 116 cells/μL (IQR 95-181)]. When achieving VL cure, KAtex results were negative in 19 (43%), weak/moderate (1+/2+) in 10 (23%), and strongly positive (3+) in 15 patients (34%). Over the subsequent 12 months, eight out of 44 patients (18%) relapsed. The predicted 1-year relapse risk was 6% for KAtex-negative results, 14% for KAtex 1+/2+ and 42% for KAtex 3+ results [hazard ratio of 2.2 (95% CI 0.1-34.9) for KAtex 1+/2+ and 9.8 (95% CI 1.8-82.1) for KAtex 3+, compared to KAtex negative patients; P : 0.03]. Conclusion: A simple field-deployable Leishmania urine antigen test can be used for risk stratification of initial treatment failure and VL relapse in HIV-patients. A dipstick-format would facilitate field implementation.

Background: Refractory or relapsed Hodgkin's disease (HD) occurs in 10-50% of patients. The treatment of choice for these patients is high-dose chemotherapy (HDCT) and autologous stem cell transplantation (ASCT). Response to salvage chemotherapy (SCT) partial remission (PR) is necessary before HDCT with ASCT. However, its applicability is restricted mostly to patients responding to salvage chemotherapy. Optimal salvage regimen for these patients is unclear. In this study, our aim was to compare the efficacy profiles of ifosfamide, carboplatin, and etoposide (ICE) and etoposide-steroid-cytarabine-cisplatin (ESHAP) (cytosine arabinoside, cisplatin, and dexamethasone) regimens in the salvage treatment of relapsed or refractory HD. Materials and Methods: In this retrospective analysis, 114 patients with primary refractory or relapsed HD who received ICE or ESHAP salvage regimen were included. Results: Of 114 patients, 47 (41.2%) were females and the median age was 31.5 years. Response could be evaluated in 114 patients. Of 114 patients, 38 (33%) achieved complete remission (CR) and 21 (18.4%) achieved PR, leading to an overall response rate (ORR: CR + PR) of 51.4%. In the evaluable ICE group (n = 41), rates of CR, PR, and ORR were 21.9%, 17.1%, and 39% and in the ESHAP group (n = 73), rates of CR, PR, and ORR were 39.7%, 19.2%, and 58.9% (for ORR, P = 0.04), respectively. Conclusion: In patients with relapsed or refractory HD, treatment with ESHAP seems to have higher rates of response than ICE regimen does. PMID:28401077

Purpose: Myeloablative regimens were frequently used for medulloblastoma relapsing after craniospinal irradiation (CSI): in 1997-2002, we used repeated surgery, standard-dose and myeloablative chemotherapy, and reirradiation. Methods and Materials: In 10 patients, reinduction included sequential high-dose etoposide, high-dose cyclophosphamide/vincristine, and high-dose carboplatin/vincristine, then two myeloablative courses with high-dose thiotepa ({+-} carboplatin); 6 other patients received two of four courses of cisplatin/etoposide. Hematopoietic precursor mobilization followed high-dose etoposide or high-dose cyclophosphamide or cisplatin/etoposide therapy. After the overall chemotherapy program, reirradiation was prescribed when possible. Results: Seventeen patients were treated: previous treatment included CSI of 19.5-36 Gy with posterior fossa/tumor boost and chemotherapymore » in 16 patients. Fifteen patients were in their first and 2 in their second and third relapses, respectively. First progression-free survival had lasted a median of 26 months. Relapse sites included leptomeninges in 9 patients, spine in 4 patients, posterior fossa in 3 patients, and brain in 1 patient. Three patients underwent complete resection of recurrence, and 10 underwent reirradiation. Twelve of 14 patients with assessable tumor had an objective response after reinduction; 2 experienced progression and were not given the myeloablative courses. Remission lasted a median of 16 months. Additional relapses appeared in 13 patients continuing the treatment. Fifteen patients died of progression and 1 died of pneumonia 13 months after relapse. The only survivor at 93 months had a single spinal metastasis that was excised and irradiated. Survival for the series as a whole was 11-93 months, with a median of 41 months. Conclusions: Despite responses being obtained and ample use of surgery and reirradiation, second-line therapy with myeloablative schedules was not curative, barring a few exceptions. A salvage therapy for medulloblastoma after CSI still needs to be sought.« less

Purpose: To present a large experience (73 patients) using a standard radiotherapy (RT) protocol to prevent relapse in cranial sites where measurable metastatic neuroblastoma (NB), an adverse prognostic marker, is common. Methods and Materials: High-risk NB patients with measurable cranial disease at diagnosis or residual cranial disease after induction therapy had those sites irradiated with hyperfractionated 21 Gy; a brain-sparing technique was used for an extensive field. The patients were grouped according to the response to systemic therapy. Thus, when irradiated, Group 1 patients were in complete remission and Group 2 patients had primary refractory disease. Follow-up was from themore » start of cranial RT. Results: At 3 years, the 39 Group 1 patients had a progression-free survival rate of 51%; control of cranial disease was 79%. Two relapses involved irradiated cranial sites. Two other patients relapsed in the irradiated cranial sites 6 and 12 months after a systemic relapse. At 3 years, the 34 Group 2 patients had a progression-free survival rate of 33%; control of cranial disease was 52%. Group 2 included 19 patients who had residual cranial (with or without extracranial) disease. The cranial sites showed major (n = 13), minor (n = 2), or no response (n = 4) to RT. Five patients had progression in the cranial RT field at 10-27 months. Group 2 also included 15 patients who had persistent NB in extracranial, but not cranial, sites. Of these 15 patients, 2 relapsed in the irradiated cranial sites and elsewhere at 8 and 14 months. Cranial RT was well tolerated, with no Grade 2 or greater toxicity. Conclusion: Hyperfractionated 21-Gy cranial RT might help control NB and is feasible without significant toxicity in children.« less

Background Patients with tuberculosis require retreatment if they fail or default from initial treatment or if they relapse following initial treatment success. Outcomes among patients receiving a standard World Health Organization Category II retreatment regimen are suboptimal, resulting in increased risk of morbidity, drug resistance, and transmission.. In this study, we evaluated the risk factors for initial treatment failure, default, or early relapse leading to the need for tuberculosis retreatment in Morocco. We also assessed retreatment outcomes and drug susceptibility testing use for retreatment patients in urban centers in Morocco, where tuberculosis incidence is stubbornly high. Methods Patients with smear- or culture-positive pulmonary tuberculosis presenting for retreatment were identified using clinic registries in nine urban public clinics in Morocco. Demographic and outcomes data were collected from clinical charts and reference laboratories. To identify factors that had put these individuals at risk for failure, default, or early relapse in the first place, initial treatment records were also abstracted (if retreatment began within two years of initial treatment), and patient characteristics were compared with controls who successfully completed initial treatment without early relapse. Results 291 patients presenting for retreatment were included; 93% received a standard Category II regimen. Retreatment was successful in 74% of relapse patients, 48% of failure patients, and 41% of default patients. 25% of retreatment patients defaulted, higher than previous estimates. Retreatment failure was most common among patients who had failed initial treatment (24%), and default from retreatment was most frequent among patients with initial treatment default (57%). Drug susceptibility testing was performed in only 10% of retreatment patients. Independent risk factors for failure, default, or early relapse after initial treatment included male gender (aOR = 2.29, 95% CI 1.10-4.77), positive sputum smear after 3 months of treatment (OR 7.14, 95% CI 4.04-13.2), and hospitalization (OR 2.09, 95% CI 1.01-4.34). Higher weight at treatment initiation was protective. Male sex, substance use, missed doses, and hospitalization appeared to be risk factors for default, but subgroup analyses were limited by small numbers. Conclusions Outcomes of retreatment with a Category II regimen are suboptimal and vary by subgroup. Default among patients receiving tuberculosis retreatment is unacceptably high in urban areas in Morocco, and patients who fail initial tuberculosis treatment are at especially high risk of retreatment failure. Strategies to address risk factors for initial treatment default and to identify patients at risk for failure (including expanded use of drug susceptibility testing) are important given suboptimal retreatment outcomes in these groups.

Alemtuzumab, an anti-CD52 antibody, is proven to be more efficacious than interferon beta-1a in the treatment of relapsing-remitting multiple sclerosis, but its efficacy relative to more potent immunotherapies is unknown. We compared the effectiveness of alemtuzumab with natalizumab, fingolimod, and interferon beta in patients with relapsing-remitting multiple sclerosis treated for up to 5 years. In this international cohort study, we used data from propensity-matched patients with relapsing-remitting multiple sclerosis from the MSBase and six other cohorts. Longitudinal clinical data were obtained from 71 MSBase centres in 21 countries and from six non-MSBase centres in the UK and Germany between Nov 1, 2015, and June 30, 2016. Key inclusion criteria were a diagnosis of definite relapsing-remitting multiple sclerosis, exposure to one of the study therapies (alemtuzumab, interferon beta, fingolimod, or natalizumab), age 65 years or younger, Expanded Disability Status Scale (EDSS) score 6·5 or lower, and no more than 10 years since the first multiple sclerosis symptom. The primary endpoint was annualised relapse rate. The secondary endpoints were cumulative hazards of relapses, disability accumulation, and disability improvement events. We compared relapse rates with negative binomial models, and estimated cumulative hazards with conditional proportional hazards models. Patients were treated between Aug 1, 1994, and June 30, 2016. The cohorts consisted of 189 patients given alemtuzumab, 2155 patients given interferon beta, 828 patients given fingolimod, and 1160 patients given natalizumab. Alemtuzumab was associated with a lower annualised relapse rate than interferon beta (0·19 [95% CI 0·14-0·23] vs 0·53 [0·46-0·61], p<0·0001) and fingolimod (0·15 [0·10-0·20] vs 0·34 [0·26-0·41], p<0·0001), and was associated with a similar annualised relapse rate as natalizumab (0·20 [0·14-0·26] vs 0·19 [0·15-0·23], p=0·78). For the disability outcomes, alemtuzumab was associated with similar probabilities of disability accumulation as interferon beta (hazard ratio [HR] 0·66 [95% CI 0·36-1·22], p=0·37), fingolimod (1·27 [0·60-2·70], p=0·67), and natalizumab (0·81 [0·47-1·39], p=0·60). Alemtuzumab was associated with similar probabilities of disability improvement as interferon beta (0·98 [0·65-1·49], p=0·93) and fingolimod (0·50 [0·25-1·01], p=0·18), and a lower probability of disability improvement than natalizumab (0·35 [0·20-0·59], p=0·0006). Alemtuzumab and natalizumab seem to have similar effects on annualised relapse rates in relapsing-remitting multiple sclerosis. Alemtuzumab seems superior to fingolimod and interferon beta in mitigating relapse activity. Natalizumab seems superior to alemtuzumab in enabling recovery from disability. Both natalizumab and alemtuzumab seem highly effective and viable immunotherapies for multiple sclerosis. Treatment decisions between alemtuzumab and natalizumab should be primarily governed by their safety profiles. National Health and Medical Research Council, and the University of Melbourne.

Background Most people who quit smoking relapse within a year of quitting. Little is known about what prompts renewed quitting after relapse or how often this results in abstinence. Purpose To identify rates, efficacy, and predictors of renewed quit attempts after relapse during a one-year follow-up. Methods Primary care patients in a comparative effectiveness trial of smoking cessation pharmacotherapies reported daily smoking every 6–12 weeks for 12 months to determine relapse, renewed quitting, and 12-month abstinence rates. Results Of 894 known relapsers, 291 (33%) renewed quitting for at least 24 hours and 99 (34%) of these were abstinent at follow-up. The average latency to renewed quitting was 106 days and longer latencies predicted greater success. Renewed quitting was more likely for older, male, less dependent smokers, and later abstinence was predicted by fewer depressive symptoms and longer past abstinence. Conclusions Renewed quitting is common and produces meaningful levels of cessation. PMID:24796541

ABSTRACT Acute myeloid leukemia is a hematopoietic stem cell neoplastic disease associated with high morbidity and mortality. The presence of FLT3 internal tandem duplication mutations leads to high rates of relapse and decreased overall survival. Patients with FLT3 internal tandem duplication are normally treated with hematopoietic stem cell transplantation in first complete remission. Nevertheless, the incidence of post-transplant relapse is considerable in this group of patients, and the management of this clinical condition is challenging. The report describes the outcomes of patients with FLT3 internal tandem duplication positive acute myeloid leukemia who relapsed after allogeneic hematopoietic stem cell transplantation and were treated with the combination of re-induction chemotherapy, donor lymphocyte infusion, sorafenib and azacitidine. Three cases are described and all patients achieved prolonged complete remission with the combined therapy. The combination of induction chemotherapy followed by donor lymphocyte infusion, and the maintenance with azacitidine and sorafenib can be effective approaches in the treatment of post-hematopoietic stem cell transplant and relapsed FLT3 internal tandem duplication positive acute myeloid leukemia patients. This strategy should be further explored in the context of clinical trials. PMID:28746590

Fms-like tyrosine kinase 3 internal tandem duplication (FLT3-ITD)-positive acute myeloid leukaemia (AML) relapsing after allogeneic stem cell transplantation (allo-SCT) has a dismal prognosis with limited therapeutic options. FLT3-ITD kinase inhibition is a reasonable but palliative experimental treatment alternative in this situation. Information on long-term outcome is not available. We performed a long-term follow-up analysis of a previously reported cohort of 29 FLT3-ITD-positive AML patients, which were treated in relapse after allo-SCT with sorafenib monotherapy. With a median follow-up of 7.5 years, 6 of 29 patients (21%) are still alive. Excluding one patient who received a second allo-SCT, five patients (17%) achieved sustained complete remissions with sorafenib. Four of these patients are in treatment-free remission for a median of 4.4 years. Sorafenib may enable cure of a proportion of very poor risk FLT3-ITD-positive AML relapsing after allo-SCT.

A characteristic thyroid ultrasonographic picture with diffuse or scattered low echogenicity has been described in Graves' disease (GD). Thyroid hypoechogenicity in GD at onset has been considered a prognostic index of relapse after medical treatment; moreover, thyroid hypoechogenicity is regularly observed in GD at the onset, but not in patients with 'burned-out' disease. The aim of this study was to evaluate the usefulness of thyroid hypoechogenicity changes in predicting GD relapse. Longitudinal prospective study of previously untreated patients with GD. Thirty-nine consecutive patients aged 10-72 years were treated with methimazole (MMI) for 12-24 months on a titration regimen. Evaluation of patients in remission or with relapse was done 12 and 24 months after MMI withdrawal. Thyroid ultrasonography and TSH receptor antibodies (TRAb) were evaluated in basal conditions and then one month after MMI withdrawal. Thyroid hypoechogenicity score (assessed by the same observer with the same equipment) was graded as: 0 absent; 1 mild; 2 moderate; 3 marked. At the withdrawal evaluation a score < 2 and a TRAb value < 10 U/l were considered as normal. Twelve and 24 months after withdrawal, there were 10 (25.6%) and 17 (44.7%) relapses, respectively. Neither thyroid hypoechogenicity score nor TRAb values evaluated in basal conditions, showed significant differences between patients remaining euthyroid and those who became again hyperthyroid. In the whole group, the thyroid hypoechogenicity score was significantly lower at the withdrawal than in basal conditions (1.1 +/- 1.1 vs 2 +/- 0.8; P < 0.0001); it was significantly lower in patients in remission (P < 0.001), but not in those who relapsed. The thyroid hypoechogenicity score at withdrawal was normal in 23/29 (79.3%) of patients still euthyroid and in 4/10 (40%) of those who relapsed up to the 12th month (P < 0.05); it was normal in 19/21 (90.4%) of patients still euthyroid and in 7/17 (41.2%) of those who relapsed up to the 24th month (P < 0.05). A normal thyroid hypoechogenicity score at withdrawal of MMI had a higher specificity (0.95) and sensitivity (0.59) with respect to TRAb values (0.86 and 0.53, respectively) for the prediction of the relapse of hyperthyroidism at the 24th month. Basal thyroid hypoechogenicity cannot be used as an index of relapse of GD. MMI treatment induces evident changes in thyroid hypoechogenicity, mainly in patients who subsequently go into remission. The absence or a low grade of thyroid hypoechogenicity after MMI treatment seems to be a favourable prognostic index of remission of hyperthyroidism in GD.

Cytomegalovirus (CMV) infection is a major infectious complication after allogeneic hematopoietic cell transplantation (allo-HSCT). Recently, it was reported that CMV reactivation is associated with a decreased risk of relapse in patients with acute myeloid leukemia (AML). The aim of this study was to evaluate the impact of early CMV reactivation on the incidence of disease relapse after allo-HSCT in a large cohort of patients. The Japan Society for Hematopoietic Cell Transplantation's Transplantation-Related Complication Working Group retrospectively surveyed the database of the Transplant Registry Unified Management Program at the Japan Society for Hematopoietic Cell Transplantation. Patients with AML (n = 1836), acute lymphoblastic leukemia (ALL, n = 911), chronic myeloid leukemia (CML, n = 223), and myelodysplastic syndrome (MDS, n = 569) who underwent their first allo-HSCT from HLA-matched related or unrelated donors between 2000 and 2009 and who survived without disease relapse until day 100 after transplantation were analyzed. Patients who received umbilical cord blood transplantation were not included. Patients underwent surveillance by pp65 antigenemia from the time of engraftment, and the beginning of preemptive therapy was defined as CMV reactivation. Cox proportional hazards models were used to evaluate the risk factors of relapse, nonrelapse, and overall mortality. CMV reactivation and acute/chronic graft-versus-host disease (GVHD) were evaluated as time-dependent covariates. CMV reactivation was associated with a decreased incidence of relapse in patients with AML (20.3% versus 26.4%, P = .027), but not in patients with ALL, CML, or MDS. Among 1836 patients with AML, CMV reactivation occurred in 795 patients (43.3%) at a median of 42 days, and 436 patients (23.7%) relapsed at a median of 221 days after allo-HSCT. Acute GVHD grades II to IV developed in 630 patients (34.3%). By multivariate analysis considering competing risk factors, 3 factors were significantly associated with a decreased risk of AML relapse and 1 factor with an increased risk of AML relapse: CMV reactivation (hazard ratio [HR], .77; 95% confidence interval [CI], .59 to .99), unrelated donor compared with related donor (HR, .59; 95% CI, .42 to .84), development of chronic GVHD (HR, .77; 95% CI, .60 to .99), and pretransplantation advanced disease status compared with standard disease status (HR, 1.99; 95% CI, 1.56 to 2.52). However, CMV reactivation was associated with increased nonrelapse mortality (HR, 1.60; 95% CI, 1.18 to 2.17) and overall mortality (HR, 1.37; 95% CI, 1.11 to 1.69). A beneficial effect of CMV reactivation on subsequent risk of relapse was observed in patients with AML but not in those with other hematological malignancies. However, this benefit was nullified by the increased nonrelapse mortality. The underlying mechanism is unclear; however, immunological activation against CMV reactivation plays an essential role in this association. Thus, immune augmentation treatment options, including vaccination and adoptive T cell transfer, may be useful to take advantage of the efficacy of CMV reactivation with minimal increase in nonrelapse mortality.

Antithyroid drug (ATD) is a widely used treatment for Graves' disease (GD). However, its long-term efficiency remains unclear. This study investigated the long-term disease prognosis and predictive factors for relapse in ATD-treated GD patients. Newly diagnosed, ATD-treated GD patients with at least four years of follow-up were recruited (n = 187). Remission was defined as maintaining a euthyroid status for more than one year after ATD withdrawal. During 11.1 years (range 4.0-23.7 years) of median follow-up, overall, 51.9% of the newly diagnosed ATD-treated GD patients achieved remission, 32.1% continued ATD treatment, and 13.4% underwent other ablation treatments. The 10-year remission rates were higher in the first (34.2%) and second (25.5%) ATD courses than in any of the other subsequent ATD courses, and decreased as ATD treatments were repeated. The 10-year relapse rate was the highest after the third ATD treatment (71.4%) compared with that after the first (60.5%) and second (58.3%) courses. Longer duration of ATD treatment (odds ratio [OR] = 1.4 [confidence interval (CI) 1.2-1.7], p < 0.001), higher number of relapses (OR = 4.7 [CI 2.3-9.8], p < 0.001), and moderate to severe Graves' ophthalmopathy (OR = 4.1 [CI 1.1-15.2], p = 0.032) were associated with persistent disease status. A second course of ATD can be considered for GD patients after the first relapse because the chance of remission and the relapse rate are similar to the one after the first ATD treatment course. For GD patients with more than two relapses, or with an ATD treatment duration of more than four to five years, low-dose maintenance of ATD or ablative treatment needs to be considered.

Purpose Salvage chemotherapy followed by high-dose therapy and autologous stem-cell transplantation (ASCT) is the standard treatment for relapsed diffuse large B-cell lymphoma (DLBCL). Salvage regimens have never been compared; their efficacy in the rituximab era is unknown. Patients and Methods Patients with CD20+ DLBCL in first relapse or who were refractory after first-line therapy were randomly assigned to either rituximab, ifosfamide, etoposide, and carboplatin (R-ICE) or rituximab, dexamethasone, high-dose cytarabine, and cisplatin (R-DHAP). Responding patients received high-dose chemotherapy and ASCT. Results The median age of the 396 patients enrolled (R-ICE, n = 202; R-DHAP, n = 194) was 55 years. Similar response rates were observed after three cycles of R-ICE (63.5%; 95% CI, 56% to 70%) and R-DHAP (62.8%; 95 CI, 55% to 69%). Factors affecting response rates (P < .001) were refractory disease/relapse less than versus more than 12 months after diagnosis (46% v 88%, respectively), International Prognostic Index (IPI) of more than 1 versus 0 to 1 (52% v 71%, respectively), and prior rituximab treatment versus no prior rituximab (51% v 83%, respectively). There was no significant difference between R-ICE and R-DHAP for 3-year event-free survival (EFS) or overall survival. Three-year EFS was affected by prior rituximab treatment versus no rituximab (21% v 47%, respectively), relapse less than versus more than 12 months after diagnosis (20% v 45%, respectively), and IPI of 2 to 3 versus 0 to 1 (18% v 40%, respectively). In the Cox model, these parameters were significant (P < .001). Conclusion In patients who experience relapse more than 12 months after diagnosis, prior rituximab treatment does not affect EFS. Patients with early relapses after rituximab-containing first-line therapy have a poor prognosis, with no difference between the effects of R-ICE and R-DHAP. PMID:20660832

The budget impact of introducing delayed-release dimethyl fumarate for treatment of relapse-remitting multiple sclerosis in Canada.

2015-01-01

Multiple sclerosis (MS) causes significant disability globally and is especially prevalent in Canada. Delayed-release dimethyl fumarate (DMF; also known as gastro-resistant DMF) is an orally administered disease-modifying treatment (DMT) for patients with relapsing-remitting MS (RRMS) that is currently on the market in the US, Australia, Canada, and Europe. A budget impact model (BIM) was developed to assess the financial consequences of introducing DMF for treatment of RRMS in Canada. A BIM calculated the financial consequences of introducing DMF in Canada over 3 years based on RRMS prevalence, treatment market share, and clinical effects. RRMS prevalence in Canada was derived from published literature and natural relapse rates, and disease state distribution from clinical trial data. It was conservatively assumed that 100% of RRMS patients were treated with a DMT. DMF was assumed to absorb market share proportionally from the following current treatments: interferon beta-1a-IM, interferon beta-1a-SC, interferon beta-1b, and glatiramer acetate. Treatment efficacy, in terms of relapse rate reductions and treatment discontinuation rates, was determined from mixed treatment comparison. Treatment costs (including costs of acquisition, monitoring, and administration) and cost of relapse were considered. Deterministic one-way sensitivity analyses were conducted to assess the most sensitive input parameters. Over 3 years, the introduction of DMF resulted in an average annual increase of CAD417 per treated patient per year, with reductions in costs associated with relapses (CAD192/patient/year) partially offsetting increased drug acquisition costs (CAD602/patient/year). On a population level, the average annual cost increase was CAD24,654,237, a CAD 0.68 increase per population covered by the Canadian healthcare system. The main drivers of budget impact were drop-out rates, proportion of RRMS patients treated, and market share assumptions. The acquisition costs of DMF for treatment of RRMS are predicted to be partially offset by reduced costs of relapses in the Canadian healthcare system.

Evaluation of the Risk of Relapse in Ulcerative Colitis According to the Degree of Mucosal Healing (Mayo 0 vs 1): A Longitudinal Cohort Study.

Mucosal healing in ulcerative colitis (UC) has become a common endpoint in most clinical trials and a relevant therapeutic goal in clinical practice. Despite important differences between endoscopic Mayo scores 0 and 1, both scores are considered as mucosal healing in most important trials. The aim of the present study was to evaluate the risk of relapse in UC patients according to the degree of mucosal healing (endoscopic Mayo scores of 0 and 1). A prospective longitudinal cohort study was designed. All UC patients who presented with mucosal healing at colonoscopy were consecutively included. Mucosal healing was defined as an endoscopic Mayo score of 0 or 1. Clinical relapse was defined as the need for therapy to induce remission, any treatment escalation, hospitalization or colectomy. All clinical relapses were evaluated at months 6 and 12 after study entry. Results were subjected to unconditional stepwise logistic and Kaplan-Meier regression analysis. One hundred and eighty-seven consecutive UC patients (126 [67.3%] with Mayo score 0 and 61 [32.7%] with Mayo score 1) were included. Of patients with Mayo scores 0 and 1, 9.4 and 36.6% respectively presented a relapse during the first 6 months of follow-up (p < 0.001). The only factor independently associated with UC relapses in the multivariate analysis was an endoscopic Mayo score of 1 (odds ratio 6.27, 95% confidence interval 2.73-14.40, p < 0.001). Patients with an endoscopic Mayo score of 1 have a higher risk of relapse than those with a score of 0. The concept of mucosal healing should be limited to patients with an endoscopic Mayo score of 0. Copyright © 2015 European Crohn’s and Colitis Organisation (ECCO).

The Development and Current Use of BCL-2 Inhibitors for the Treatment of Chronic Lymphocytic Leukemia

PubMed Central

Lampson, Benjamin L.; Davids, Matthew S.

2017-01-01

The BCL-2 family of proteins integrates pro- and anti-apoptotic signals within the cell and is responsible for initiation of caspase-dependent apoptosis. Chronic lymphocytic leukemia (CLL) cells are particularly dependent on the anti-apoptotic protein BCL-2 for their survival, making this an attractive therapeutic target in CLL. Several early efforts to create inhibitors of the anti-apoptotic family members faced significant challenges, but eventually the BCL-2 specific inhibitor venetoclax moved forward in CLL. Overall and complete response rates to venetoclax monotherapy in relapsed, refractory CLL are approximately 80% and 20%, respectively, even in patients with high risk 17p deletion. Toxicities have been manageable and include neutropenia, diarrhea, and nausea. The risk of tumor lysis syndrome (TLS), seen in early experience with the drug, has been mitigated by the use of appropriate TLS risk assessment, prophylaxis, and management. Future studies of venetoclax will focus on combination approaches, predictive biomarker discovery, and mechanisms of resistance. PMID:28116634

Hypercalcemia and severe osteolytic lesions are rare complications of acute lymphoblastic leukemia (ALL) in childhood. We report a case of a 3 years old boy who presented with prolonged fever, nausea, vomiting and increasing lower limbs pain. Skeletal X-rays and CT scan showed severe osteolytic lesions of the skull and extremities. Her physical examination showed multiple cervical lymph nodes. In laboratory tests, he had severe hypercalcemia. Parathyroid hormone (PTH) was not elevated. Despite the absence of circulating blasts, bone marrow biopsy revealed B-precursor (ALL). Hypercalcemia was initially treated with intravenous isotonic sodium chloride solution and diuretics but the serum calcium level normalized only after the beginning of corticosteroids and chemotherapy. The child responded initially to chemotherapy and eventually relapsed and died of septic shock. Acute leukemia must be considered in differential diagnosis in patients with hypercalcemia. A detailed examination even when there no circulating blasts in their peripheral blood smear, and if in doubt bone marrow aspiration should must be taken into consideration. PMID:28690758

Purpose Clinical characteristics, therapeutic approaches, and prognosis of late relapse (LR) in patients with classic Hodgkin lymphoma (cHL) are poorly understood. We performed a comprehensive analysis of LR of Hodgkin lymphoma (LR-HL). Methods To estimate the incidence of LR-HL, we retrospectively analyzed 6,840 patients with cHL included in the German Hodgkin Study Group trials HD7 to HD12. Patients who experienced a relapse > 5 years into remission were compared with patients in continued remission for > 5 years and with those who experienced a relapse ≤ 5 years after first diagnosis. Results With a median observation time of 10.3 years, 141 incidences of LR-HL were observed. Cumulative incidences at 10, 15, and 20 years rose linearly and were 2.5%, 4.3%, and 6.9%, respectively. The standardized incidence ratio for HL with respect to age- and sex-matched German reference data was 84.5 (95% CI, 71.2 to 99.7). LR-HL was more frequently observed in patients with early-stage favorable than unfavorable or advanced stage at first diagnosis (15-year cumulative incidence, 5.3% v 3.9% and 3.9%, respectively; P = .01). Overall survival from first diagnosis was worse after LR compared with nonrelapse survivors (10-year estimate, 95.8% v 86.1%; hazard ratio, 2.5; 95% CI, 1.7 to 3.5; P < .001). In patients with LR-HL, survival was better compared with 466 patients with earlier relapse (hazard ratio, 0.6; 95% CI, 0.4 to 0.9, P = .01). Forty-four percent and 49% of patients with LR-HL and earlier relapse, respectively, received stem cell transplantations. Conclusion Apart from treatment-associated adverse effects, survivors after initially successful therapy for cHL are at an 85-fold risk for recurrence of disease compared with the general German population. After risk-adapted treatment strategies, especially in early-stage favorable HL, regular clinical follow-up is recommended for timely detection of LR-HL. With adequate treatment, prognosis of LR-HL is better compared with early relapses.

In acute lymphoblastic leukemia, central nervous system prophylaxis with irradiation plus intrathecal methotrexate (i.t. MTX) reduces the incidence of CNS relapse to 7%-15%. However, increased evidence of CNS delayed toxicity was recognized mainly in children as CT scan abnormalities and neuropsychologic alterations. Two questions were analyzed: (1) Will further doses of i.t. methotraxate and dexamethasone (i.t. MTX-DMT) decrease the incidence of CNS relapse. (2) Is i.t. MTX-DMT given during induction and maintenance as effective as cranium irradiation plus i.t. MTX-DMT. Incidence of primary CNS relapse in i.t. MTX-DMT-treated patients with a WBC count < 50,000 and in the untreated groupmore » was 11%. In patients with a WBC count > 50,000, it was 16% in the treated group and 19% in the control group. These patients were compared with patients which had received 3 doses of i.t. MTX-DMT alone during induction, 3 doses weekly during the first month of remission, and quarterly thereafter. The incidence of leukemia at 60 mo in patients with a WBC count < 50,000 was 20% in the irradiated group and 32% in the group with i.t. MTX-DMT alone. The relapse-free survival at 60 mo was 26% and 41%, respectively, (p < 0.0005). The incidence in patients with a WBC count > 50,000 at 48 mo was 28% and 42% in the irradiated and nonirradiated group respectively. Complete remission remained at 15% and 16% respectively of patients disease-free at 48 mo. We conclude that (A) after cranial irradiation plus i.t. MTX-DMT X 5, the use of additional doses of i.t. MTX-DMT is not of further benefit in preventing CNS relapse; (B) use of i.t. MTX-DMT alone compares with cranial irradiation plus i.t. MTX-DMT in incidence of CNS relapse; and (C) relapse-free survival and survival in patients with a WBC count < 50.000 were significantly longer in those without cranial irradiation.« less

The prognosis for children with high-risk relapsed acute lymphoblastic leukemia (ALL) is poor. Here, we assessed the prognostic importance of response during induction and consolidation treatment prior to hematopoietic stem cell transplantation (HSCT) aiming to evaluate the best time to assess minimal residual disease (MRD) for intervention strategies and in future trials in high-risk ALL relapse patients. Included patients (n=125) were treated uniformly according to the ALL-REZ BFM (Berlin-Frankfurt-Münster) 2002 relapse trial (median follow-up time=4.8 years). Patients with MRD ⩾10(-3) after induction treatment (76/119, 64%) or immediately preceding HSCT (19/71, 27%) had a significantly worse probability of disease-free survival 10 years after relapse treatment begin, with 26% (±6%) or 23% (±7%), respectively, compared with 58% (±8%) or 48% (±7%) for patients with MRD <10(-3). Conventional intensive consolidation treatment reduced MRD to <10(-3) before HSCT in 63% of patients, whereas MRD remained high or increased in the rest of this patient group. Our data support that MRD after induction treatment can be used to quantify the activity of different induction treatment strategies in phase II trials. MRD persistence at ⩾10(-3) before HSCT reflects a disease highly resistant to conventional intensive chemotherapy and requiring prospective controlled investigation of new treatment strategies and drugs.

Detection of minimal residual disease (MRD) after induction and consolidation therapy is highly predictive of outcome for childhood acute lymphoblastic leukaemia (ALL) and is used to identify patients at high risk of relapse in several current clinical trials. To evaluate the prognostic significance of MRD at other treatment phases, MRD was measured by real-time quantitative polymerase chain reaction on a selected group of 108 patients enrolled on the Australian and New Zealand Children's Cancer Study Group Study VII including 36 patients with a bone marrow or central nervous system relapse and 72 matched patients in first remission. MRD was prognostic of outcome at all five treatment phases tested: at day 15 (MRD > or = 5 x 10(-2), log rank P < 0.0001), day 35 (> or =1 x 10(-2), P = 0.0001), 4 months (> or =5 x 10(-4), P < 0.0001), 12 months (MRD > or = 1 x 10(-4), P = 0.006) and 24 months (MRD > or = 1 x 10(-4), P < 0.0001). Day 15 was the best early MRD time-point to differentiate between patients with high, intermediate and low risk of relapse. MRD testing at 12 and particularly at 24 months, detected molecular relapses in some patients up to 6 months before clinical relapse. This raised the question of whether a strategy of late monitoring and salvage therapy will improve outcome.

In patients who have history of lymphoma, a positive positron emission tomography (PET) scan is frequently considered as good evidence for relapse and/or persistent disease. Thus, lymph node biopsy is not always done to confirm the diagnosis of relapse or refractory lymphoma before a patient is subjected to further chemotherapy. We report a case of patient with history of T cell lymphoblastic lymphoma who presented again with inguinal lymphadenopathy and positive study on positron emission tomography suggestive of lymphoma relapse. This was pathologically proven to be cat scratch disease. This case suggests that in the immunocompromised patients who had history of lymphoma, infectious etiology should be ruled out for PET scan-positive lymphadenopathy.

Stopping long-term nucleos(t)ide analogue therapy increases HBsAg loss rates in HBeAg-negative patients. Viral rebound may induce immune responses facilitating functional cure. We analyzed which factors are associated with timing of virological relapse in 220 Asian HBeAg-negative patients from the prospective ABX203 vaccine study. Unexpectedly, only the type of antiviral therapy was significantly associated with early virological relapse, defined as HBV DNA > 2,000 IU/ml until week 12 and occurred earlier in patients treated with tenofovir versus entecavir (median time 6 versus 24 weeks, p < 0.0001). This should be considered for future trials and monitoring of patients after treatment discontinuation.

Objective: To determine the oxidative stress markers in serum from patients with relapsing-remitting multiple sclerosis. Methods: Blood samples from healthy controls and 22 patients 15 women (7 aged from 20 to 30 and 8 were > 40 years old) and 7 men (5 aged from 20 to 30 and 2 were > 40 years old) fulfilling the McDonald Criteria and classified as having Relapsing-Remitting Multiple Sclerosis accordingly with Lublin were collected for oxidative stress markers quantification. Results: Nitric oxide metabolites (nitrates/nitrites), lipid peroxidation products (malondialdehyde plus 4-hidroxialkenals), and glutathione peroxidase activity were significantly increased in serum of subjects with relapsing-remitting multiple sclerosis in comparison with that of healthy controls. These data support the hypothesis that multiple sclerosis is a component closely linked to oxidative stress. PMID:19242067

Background A post-marketing surveillance (PMS) study was conducted with a 1-year observation period to assess the safety and efficacy of lamotrigine in routine clinical practice in patients with bipolar disorder (BD). Patients and methods Central enrollment method was used to recruit patients diagnosed with BD who were being treated for the first time with lamotrigine to prevent the recurrence/relapse of BD mood episodes. Adverse drug reactions (ADRs) and recurrence/relapse were assessed. Improvement of mania and depression was also assessed using the Hamilton’s Rating Scale for Depression (HAM-D) and the Young Mania Rating Scale (YMRS) at treatment initiation, 4–6 months post treatment initiation, and 10–12 months post treatment initiation. Results A total of 237/989 patients (24.0%) reported ADRs, most commonly rash (9.1%), and the incidence of serious ADRs was 3.3% (33/989 patients). Skin disorders occurred in 130 patients (13.1%), mostly within 8 weeks post treatment. A total of 237/703 patients (33.7%) experienced recurrence/relapse of mood episodes. The 25th percentile of the time to recurrence/relapse of mood episodes was 105 days. Remission of depression symptoms (HAM-D ≤7) occurred in 147/697 patients (21.1%) at treatment initiation, rising to 361 patients (67.4%) at 10–12 months post treatment. Remission of manic symptoms (YMRS ≤13) occurred in 615/676 patients (91.0%) at treatment initiation, rising to 500 patients (97.3%) at 10–12 months post treatment. Conclusion The results of this PMS study suggest that lamotrigine is a well-tolerated and effective drug for preventing recurrence/relapse of BD in clinical practice. PMID:28652744

Purpose To characterize the toxicity, pharmacokinetics, and pharmacodynamics of selinexor, a selective inhibitor of nuclear export, when combined with fludarabine and cytarabine, in children with relapsed or refractory leukemia. Patients and Methods Eighteen patients with relapsed or refractory acute leukemia were enrolled in the SELHEM (Selinexor With Fludarabine and Cytarabine for Treatment of Refractory or Relapsed Leukemia or Myelodysplastic Syndrome) clinical trial (NCT02212561). Selinexor, initially at 30 mg/m 2 per dose, was given orally on days 1, 3, 8, 10, 22, and 24 and was escalated according to a rolling-six design. Fludarabine 30 mg/m 2 and cytarabine 2 g/m 2 were administered on days 15 to 19. Pharmacokinetic and pharmacodynamic studies were performed on days 1 and 22. Response evaluations were performed on day 15 and at the completion of course 1. Results Among the 17 patients who were evaluable for toxicity, three were treated at 30 mg/m 2 , three at 40 mg/m 2 , six at 55 mg/m 2 , and five at 70 mg/m 2 . The most common grade 3 nonhematologic toxicity was asymptomatic hyponatremia. Two patients who were treated at 70 mg/m 2 experienced reversible cerebellar toxicity, thereby defining the dose-limiting toxicity. Pharmacokinetic parameters demonstrated that plasma exposure was dose proportional. Fifteen of 16 patients demonstrated at least a twofold increase of XPO1 mRNA, indicating inhibition of the XPO1 protein. In this group of heavily pretreated, relapsed, and refractory patients, seven of 15 evaluable patients (47%) achieved complete response or complete response with incomplete count recovery. Conclusion Selinexor, in combination with fludarabine and cytarabine, is tolerable at doses up to 55 mg/m 2 in pediatric patients with relapsed or refractory leukemia. All patients who received selinexor at ≥ 40 mg/m 2 demonstrated XPO1 target inhibition. Response rates are promising and will be further explored in a phase II trial.

Class III malocclusions are usually growth related discrepancies, which often become more severe when growth is completed Orthognathic surgery can be a part of the treatment plan, although a good number of cases can be treated non-surgically by camouflage treatment. The purpose of this report is to review the relapse tendency in patients treated non-surgically. A simple technique is described to combat one such post-treatment relapse condition in an adult patient who had undergone orthodontic treatment by extraction of a single lower incisor.

Numb chin syndrome is another rare syndrome associated with aggressive malignancies. Survival of these syndromes is dictated by the underlying disease and is usually dismal. Our 35-year-old patient experienced an early relapse of Burkitt lymphoma accompanied by syndromes, achieved second complete remission and underwent allogeneic stem cell transplantation. He remains alive and well >2 years after the transplant. To our knowledge, this is the longest reported survival of the two syndromes in the setting of BL relapse. PMID:25068102

The presence of TEL/AML1 fusion gene in childhood acute lymphoblastic leukaemia (ALL) defines a subgroup of patients with better than average outcome. However, the prognostic significance of this aberration has recently been disputed by the Berlin-Frankfurt-Münster (BFM) study group due to its relatively high incidence found in relapsed patients (19.6% and 21.9%, in two cohorts). In contrast, only four out of 45 (8.9%) unselected relapsed patients (all of whom had been treated according to BFM protocols) in the Czech Republic carry this fusion. From March 1995 to June 1998, 41 out of 190 (21.6%) newly diagnosed children with ALL were TEL/AML1-positive. There is a statistically significant difference between the incidence of TEL/AML1 fusion at diagnosis and at relapse within our group (P = 0.035). Interim analysis of the minimal residual disease (MRD) detection shows heterogeneity within the group of newly diagnosed TEL/AML1-positive leukaemias--10 out of 24 patients tested at the end of induction therapy had detectable levels of MRD. However, only one of these patients reached relapse-predictive level (10(-3)) of MRD. In conclusion, we corroborate low frequency of TEL/AML1 positivity among relapsed patients with ALL among Czech children who are treated by the BFM protocols. Moreover, we demonstrate different patterns of bone marrow clean-up in TEL/AML1-positive patients.

Environmental exposure is a likely risk factor for the development of pulmonary Mycobacterium avium complex (MAC) disease. The influence of environmental exposure on the response to antimicrobial treatment and relapse is unknown. We recruited 72 patients with pulmonary MAC disease (male [female], 18 [54]; age, 61.7 ± 10.3 years) who initiated and completed standard three-drug regimens for more than 12 months between January 2007 and December 2011. The factors associated with sputum conversion, relapse and treatment success without relapse were retrospectively evaluated after adjustments for confounding predictors. Fifty-two patients (72.2%) demonstrated sputum conversion, and 15 patients (28.8%) relapsed. A total of 37 patients (51.4%) demonstrated treatment success. Sputum conversion was associated with negative smears (odds ratio [OR], 3.89; 95% confidence interval [CI], 1.27-12.60; P = 0.02). A relapse occurred in patients with low soil exposure after the start of treatment less frequently than in patients with high soil exposure (7/42 [16.7%] vs. 8/10 [80.0%], P = 0.0003). Treatment success was associated with low soil exposure after the beginning of treatment (OR, 13.46; 95% CI, 3.24-93.43; P = 0.0001) and a negative smear (OR, 2.97; 95% CI, 1.02-9.13; P = 0.047). Low soil exposure was independently associated with better microbiological outcomes in patients with pulmonary MAC disease after adjusting for confounding clinical, microbiological and radiographic findings.

Impaired inhibitory control contributes to the development, maintenance, and relapse of alcohol-dependence, but the neural correlates of this deficit are still unclear. Because inhibitory control has been labeled as an executive function, most studies have focused on prefrontal areas, overlooking the contribution of more "primary" structures, such as the motor system. Yet, appropriate neural inhibition of the motor output pathway has emerged as a central aspect of healthy behavior. Here, we tested the hypothesis that this motor inhibition is altered in alcohol-dependence. Neural inhibitory measures of motor activity were obtained in 20 detoxified alcohol-dependent (AD) patients and 20 matched healthy subjects, using a standard transcranial magnetic stimulation procedure whereby motor-evoked potentials (MEPs) are elicited in a choice reaction time task. Moreover, behavioral inhibition and trait impulsivity were evaluated in all participants. Finally, the relapse status of patients was assessed 1 year after the experiment. As expected, AD patients displayed poorer behavioral inhibition and higher trait impulsivity than controls. More importantly, the MEP data revealed a considerable shortage of neural motor inhibition in AD patients. Interestingly, this neural defect was strongest in the patients who ended up relapsing during the year following the experiment. Our data suggest a strong motor component in the neural correlates of altered inhibitory control in AD patients. They also highlight an intriguing relationship with relapse and the perspective of a new biomarker to follow strategies aiming at reducing relapse in AD patients.

This study analysed the outcome of 267 patients with relapse/refractory acute myeloid leukaemia (AML) who received sequential chemotherapy including fludarabine, cytarabine and amsacrine followed by reduced-intensity conditioning (RIC) and allogeneic haematopoietic stem cell transplantation (HSCT). The transplants in 77 patients were from matched sibling donors (MSDs) and those in 190 patients were from matched unrelated donors. Most patients (94·3%) were given anti-T-cell antibodies. The incidence of acute graft-versus-host disease (GVHD) of grades II-IV was 32·1% and that of chronic GVHD was 30·2%. The 3-year probability of non-relapse mortality (NRM) was 25·9%, that of relapse was 48·5%, that of GVHD-free and relapse-free survival (GRFS) was 17·8% and that of leukaemia-free survival (LFS) was 25·6%. In multivariate analysis, unrelated donor recipients more frequently had acute GVHD of grades II-IV [hazard ratio (HR) = 1·98, P = 0·017] and suffered less relapses (HR = 0·62, P = 0·01) than MSD recipients. Treatment with anti-T-cell antibodies reduced NRM (HR = 0·35, P = 0·01) and improved survival (HR = 0·49, P = 0·01), GRFS (HR = 0·37, P = 0·0004) and LFS (HR = 0·46, P = 0·005). Thus, sequential chemotherapy followed by RIC HSCT and use of anti-T-cell antibodies seems promising in patients with refractory AML. © 2016 John Wiley & Sons Ltd.

Dhakal, Sughosh; Bates, James E.; Casulo, Carla

Purpose: To evaluate the location and timing of initial recurrence in patients with diffuse large B-cell lymphoma (DLBCL) who subsequently underwent high-dose chemotherapy with autologous stem cell transplant (HDC/ASCT), to direct approaches for disease surveillance, elucidate the patterns of failure of contemporary treatment strategies, and guide adjuvant treatment decisions. Methods and Materials: We analyzed consecutive patients with DLBCL who underwent HDC/ASCT between May 1992 and March 2014 at our institution. Of the 187 evaluable patients, 8 had incomplete data, and 79 underwent HDC/ASCT as a component of initial treatment for de novo or refractory DLBCL and were excluded from furthermore » analysis. Results: The median age was 50.8 years; the median time to relapse was 1.3 years. Patients were segregated according to the initial stage at diagnosis, with early stage (ES) defined as stage I/II and advanced stage (AS) defined as stage III/IV. In total, 40.4% of the ES and 75.5% of the AS patients relapsed in sites of initial disease; 68.4% of those with ES disease and 75.0% of those with AS disease relapsed in sites of initial disease only. Extranodal relapses were common (44.7% in ES and 35.9% in AS) and occurred in a variety of organs, although gastrointestinal tract/liver (n=12) was most frequent. Conclusions: Most patients with DLBCL who relapse and subsequently undergo HDC/ASCT initially recur in the previously involved disease site(s). Time to recurrence is brief, suggesting that frequency of screening is most justifiably greatest in the early posttherapy years. © 2016 Elsevier Inc.« less

The prognosis of relapsed or refractory aggressive non-Hodgkin's lymphoma (NHL) after front-line therapy remains poor. The development of more effective and less toxic salvage regimens remains a major challenge. Survivin is a member of the family of inhibitors of apoptosis, and survivin was associated with short survival and bad prognosis. This study was to evaluate the efficacy of GDP regimen (gemcitabine, dexamethasone and cisplatin) on relapsed or refractory aggressive NHL and various prognostic factors with special emphasis on survivin and observe the . Forty-six patients with relapsed and refractory NHL, intermediate or high-grade NHL (Revised European American Lymphoma Classification), who at least one regimen were enrolled into this study, which was carried out at Department, , Tanta University from July 2012 to July 2014. The patients were treated with GDP regimen (gemcitabine 1,000 mg/m(2) on days one and eight, dexamethasone 40 mg on days 1-3, and cisplatin 25 mg/m(2) on days 1-3) every 3 weeks. The efficacy and adverse events were evaluated according to the WHO criteria. All patients were assessed for efficacy and toxicity. The overall response rate was 58.7 %. Fourteen patients showed a complete response, thirteen partial responses, twelve stable diseases, and seven progressive disease. The 24-month overall survival was 50.8 %. Survivin is associated with low overall response and shorter overall survival. Grade 3 anemia was observed in four patients, grade 3 leucopenia in six patients, grade 3 neutropenia in six patients, and grade 3 thrombocytopenia in four patients. Non-hematologic toxicity included grade 3 infection in four patients. The present schedule of GDP showed modest efficacy and mild toxicity in patients with relapsed or refractory aggressive NHL.

Here 229 relapsing Ph- ALL younger adults (18-63 years) treated within the Group for Research on Adult Acute Lymphoblastic Leukemia (GRAALL)-2003/-2005 trials were considered. Salvage regimens consisted of potentially curative therapies in 194 cases, low-intensity therapies in 21, allogeneic stem cell transplant (allo-SCT) in 6 and best supportive care in 8. Overall, 77 patients received allo-SCT after relapse. The median follow-up was 3.1 years. A second complete remission (CR2) was achieved in 121 patients (53%). In multivariate analysis, only younger age <45 years (P=0.008) and CR1 duration ⩾18 months (P=0.009) predicted CR2. Overall survival (OS) at 2 and 5 years was 19.3% (14-24%) and 13.3% (8-18%), respectively. In CR2 patients, disease-free survival (DFS) at 2 and 5 years was 29.0% (21-38%) and 25% (17-33%). In multivariate analysis, CR1 duration ⩾18 months and allo-SCT after relapse were associated with longer DFS (P<0.009 and P=0.004, respectively) and longer OS (P=0.004 and P<0.0001, respectively). In conclusion, although younger adults relapsing after pediatric-inspired ALL therapies retain a poor outcome, some of them may be cured if CR1 duration ⩾18 months and if allo-SCT can be performed in CR2. New therapies are definitely needed for these patients.

Fingolimod is a once-daily, oral sphingosine 1-phosphate receptor modulator approved for the treatment of relapsing multiple sclerosis. This post-hoc analysis of phase 3 FREEDOMS data assessed whether the effects of fingolimod are consistent among subgroups of patients defined by prior treatment history. Annualized relapse rate and safety profile of treatment with fingolimod 0.5mg, 1.25mg, or placebo once-daily for 24 months were analyzed in 1272 relapsing multiple sclerosis patients, by subgroups based on disease-modifying therapy history (treatment-naive; prior interferon-β or glatiramer acetate), reason for discontinuation of prior disease-modifying therapy (unsatisfactory therapeutic response or adverse events), and prior disease-modifying therapy duration. Both fingolimod doses significantly reduced annualized relapse rate in patients that received prior interferon-β or glatiramer acetate, discontinued prior disease-modifying therapy owing to unsatisfactory therapeutic effect, were treatment-naive, or had prior disease-modifying therapy duration of >1-3 years (P≤0.0301 for all comparisons vs placebo). Fingolimod 1.25mg resulted in greater reductions in annualized relapse rate in patients that discontinued prior disease-modifying therapy for adverse events or had prior disease-modifying therapy duration of ≤1 year or >3 years (P≤0.0194 vs placebo). Fingolimod demonstrated similar efficacy in relapsing multiple sclerosis patients regardless of prior treatment history. Clinicaltrials.gov identifier: NCT00289978. © 2013 The Authors.

Bariatric surgery is recognized as a highly effective therapy for obesity since it accomplishes sustained weight loss, reduction of obesity-related comorbidities and mortality, and improvement of quality of life. Overall, bariatric surgery is associated with a 42% reduction of the cardiovascular risk and 30% reduction of all-cause mortality. This review focuses on some nutritional consequences that can occur in bariatric patients that could potentially hinder the clinical benefits of this therapeutic option. All bariatric procedures, to variable degrees, alter the anatomy and physiology of the gastrointestinal tract; this alteration makes these patients more susceptible to developing nutritional complications, namely, deficiencies of macro- and micro-nutrients, which could lead to disabling diseases such as anemia, osteoporosis, protein malnutrition. Of note is the evidence that most obese patients present a number of nutritional deficits already prior to surgery, the most important being vitamin D and iron deficiencies. This finding prompts the need for a complete nutritional assessment and, eventually, an adequate correction of pre-existing deficits before surgery. Another critical issue that follows bariatric surgery is post-operative weight regain, which is commonly associated with the relapse of obesity-related co-morbidities. Nu-tritional complications associated with bariatric surgery can be prevented by life-long nutritional monitoring with the administration of multi-vitamins and mineral supplements according to the patient’s needs.

Backround/Objective: To assess the impact of emergency surgery and postoperative recurrence in Crohn's disease (CD) and to evaluate the disease course while observing different factors that may influence it. Methods: Information on 37 consecutive patients which were diagnosed and operated in emergency for CD complications and the the relapse rate (regarded as a second surgery) were retrospectively evaluated. Results: The risk of relapse and second surgery was increased in males under 50 years and in those who benefited from an anastomosis during the first invervention while stomy seemed to reduce the rate of surgical relapse. The median duration until relapse was 2,3 years while a percentage of 33% required reintervention. Conclusions: The majority of patients with CD will undergo at least one surgical intervention during their lifetime and one third of them will relapse requiring a second intervention. Although medical treatment has seen great advancements, surgery requirements have remained unchanged as the mainstay treatment in emergent complications of CD. The age of the patients, smoking status and the postoperative medication influence the rate of postoperative recurrence. Celsius.

It is unclear whether higher CD34 + cell doses infused for ASCT have any influence on survival or relapse in patients with lymphoma. We analyzed the correlation of infused CD34 + cell dose with relapse, survival, and hematopoietic recovery in 146 consecutive patients undergoing ASCT for lymphoma. Higher doses (>5 × 10 6 /kg) were significantly correlated with earlier hematopoietic recovery, fewer infectious episodes, lower transfusion needs. No differences were observed in lymphoma outcomes (4-year relapse incidence of 38% [95%CI: 29%-48%] in the lower dose group versus 51% [95%CI: 30%-69%] in the higher dose group, 10-year OS probabilities of 58% [95%CI: 48%-68%] versus 75% [95%CI: 59%-91%], 10-year DFS probabilities of 47% [95%CI: 37%-57%] versus 42% [95%CI: 23%-61%], p = NS for all outcomes). In this series, a higher infused CD34 + cell dose did not correlate with survival or relapse but correlated with earlier hematopoietic recovery and lower resource consumption.

Vasculitis of the peripheral nervous system (PNS) is rare. There are no controlled treatment trials, and clinical practice is guided by experience from case series and indirectly by analogy with systemic vasculitis. We identified patients (n=212) with possible vasculitic peripheral neuropathy (VPN) from the neuropathology and neurophysiology records of two centres over 28 years. Case-notes were available for 181, from which, 106 cases of clinicopathological VPN were identified. Adequate treatment data were available in 100; follow-up data, in 93. Of 106 cases, 95 had systemic vasculitis and 11 had vasculitis confined to the PNS. Pharmacological treatment (94/100 cases) was corticosteroid-based, and included cyclophosphamide in 54; 17 received additional agents. Initial stabilization was achieved in all but six. One-year survival was 90.3%. Of the nine who died in the first years (mean age 73 years), seven had received cyclophosphamide, and all but two had severe, multisystem vasculitis. The neurological relapse rate was 10%. Only one relapse occurred after cyclophosphamide treatment. Outcome was reported as good in 72% (78% in those who relapsed). Death and relapse were infrequent in treated patients. Relapse occurred almost exclusively in patients treated with prednisolone alone. Aggressive early treatment with cyclophosphamide may prevent relapse. The current management approach to VPN appears largely effective, especially if cyclophosphamide is used.

The purpose of this study was to identify whether heroin relapse is associated with changes in the functional connectivity of the default mode network (DMN) during methadone maintenance treatment (MMT). Resting-state functional magnetic resonance imaging (fMRI) data of chronic heroin relapsers (HR) (12 males, 1 female, age: 36.1 ± 6.9 years) and abstainers (HA) (11males, 2 female; age: 42.1 ± 8.1 years) were investigated with an independent component analysis to address the functional connectivity of their DMN. Group comparison was then performed between the relapsers and abstainers. Our study found that the left inferior temporal gyrus and the right superior occipital gyrus associated with DMN showed decreased functional connectivity in HR when compared with HA, while the left precuneus and the right middle cingulum had increased functional connectivity. Mean intensity signal, extracted from left inferior temporal gyrus of HR patients, showed a significant negative correlation corresponding to the degree of heroin relapse. These findings suggest that altered functional connectivity of DMN may contribute to the potential neurobiological mechanism(s) of heroin relapse and have a predictive value concerning heroin relapse under MMT.

We retrospectively studied a series of 23 patients (median age 50 years, range 29-59 years) with multiple myeloma (MM), treated in first relapse by a sequential autologous-allogeneic tandem approach. Tandem transplantation (TT) consisted in high dose melphalan (HDT) and auto-SCT followed by an (allo-SCT) preceded by two gray TBI non-myeloablative conditioning. All patients received a first HDT as frontline treatment. At day 100 post allo-SCT, complete donor chimerism was detected in 22 patients (95%). Acute GVHD was observed in 19 patients (15 grade I-II (65%) and 4 grade III-IV (17%)). Ten patients (43%) developed an extensive chronic GVHD. The non-relapse mortality at 1 year was 17%. After TT, the overall response rate was 91% (17% partial response, 35% very good partial remission and 39% complete remission). At 2 years, OS was 61%. Median event-free survival and OS were 36.8 and 60 months, respectively. Based on the propensity score matching method, a significant survival advantage could be seen in patients treated with TT as compared with non-allografted patients. Thus, allo-SCT, in TT approach, provides a high response rate with low toxicity and may improve survival of patients with relapsing MM.

Thrombotic thrombocytopenic purpura/Haemolytic uremic syndrome (TTP/HUS) is a thrombotic microangiopathy with a 6-month mortality rate of 16-29%. The present study described the clinical features, treatment regime and 6-month all-cause mortality rate of TTP/HUS patients at the London Health Sciences Centre (LHSC), Canada. Data for this retrospective cohort study were obtained from inpatient and outpatient records for all patients referred for plasma exchange therapy at LHSC, Canada between 1981 and 2006. Patients (n = 110) were categorized as: idiopathic primary (38%) or relapsed (16%), and secondary responsive (30%) or non-responsive (16%). Mortality data were available for all but three patients. The all-cause 6-month mortality rate was 19% overall and was 12% and 26% among idiopathic and secondary TTP/HUS patients, respectively. No mortality events occurred among the 17 idiopathic patients who relapsed. Relapsed patients had the least severe presenting characteristics, the fastest response time, and experienced significant improvement in the severity of clinical features between the first and final presentation. These findings suggest an excellent outcome for relapsed TTP/HUS patients. Patient education, surveillance, and aggressive plasma exchange therapy are hypothesized to improve the likelihood of survival: these hypotheses should be tested in a randomized controlled trial.

Novel therapeutic options for relapsed hairy cell leukemia.

The majority of patients with hairy cell leukemia (HCL) achieve a response to therapy with cladribine or pentostatin with or without rituximab. However, late relapses can occur. Treatment of relapsed HCL can be difficult due to a poor tolerance to chemotherapy, increased risk of infections and decreased responsiveness to chemotherapy. The identification of BRAFV600E mutations and the role of aberrant MEK kinase and Bruton's tyrosine kinase (BTK) pathways in the pathogenesis of HCL have helped to develop novel targeted therapies for these patients. Currently, the most promising therapeutic strategies for relapsed or refractory HCL include recombinant immunoconjugates targeting CD22 (e.g. moxetumomab pasudotox), BRAF inhibitors such as vemurafenib and B cell receptor signaling kinase inhibitors such as ibrutinib. Furthermore, the VH4-34 molecular variant of classic HCL has been identified to be less responsive to chemotherapy. Herein, we review the results of the ongoing clinical trials and potential future therapies for relapsed/refractory HCL.

This study was conducted to compare long-term outcomes in patients with refractory/relapsed grades 1 and 2 follicular lymphoma (FL) after allogeneic (allo) versus autologous (auto) hematopoietic cell transplantation (HCT) in the rituximab era. Adult patients with relapsed/refractory grades 1 and 2 FL undergoing first reduced-intensity allo-HCT or first autograft during 2000 to 2012 were evaluated. A total of 518 rituximab-treated patients were included. Allo-HCT patients were younger and more heavily pretreated, and more patients had advanced stage and chemoresistant disease. The 5-year adjusted probabilities, comparing auto-HCT versus allo-HCT groups for nonrelapse mortality (NRM) were 5% versus 26% (P < .0001); relapse/progression: 54% versus 20% (P < .0001); progression-free survival (PFS): 41% versus 58% (P < .001), and overall survival (OS): 74% versus 66% (P = .05). Auto-HCT was associated with a higher risk of relapse/progression beyond 5 months after HCT (relative risk [RR], 4.4; P < .0001) and worse PFS (RR, 2.9; P < .0001) beyond 11 months after HCT. In the first 24 months after HCT, auto-HCT was associated with improved OS (RR, .41; P < .0001), but beyond 24 months, it was associated with inferior OS (RR, 2.2; P = .006). A landmark analysis of patients alive and progression-free at 2 years after HCT confirmed these observations, showing no difference in further NRM between both groups, but there was significantly higher risk of relapse/progression (RR, 7.3; P < .0001) and inferior PFS (RR, 3.2; P < .0001) and OS (RR, 2.1; P = .04) after auto-HCT. The 10-year cumulative incidences of second hematological malignancies after allo-HCT and auto-HCT were 0% and 7%, respectively. Auto-HCT and reduced-intensity-conditioned allo-HCT as first transplantation approach can provide durable disease control in grades 1 and 2 FL patients. Continued disease relapse risk after auto-HCT translates into improved PFS and OS after allo-HCT in long-term survivors. Copyright © 2015 American Society for Blood and Marrow Transplantation.

To evaluate the efficacy and safety of aripiprazole versus placebo in preventing relapse of irritability symptoms associated with autistic disorder in pediatric patients. This multicenter, double-blind, randomized, placebo-controlled, relapse-prevention trial enrolled patients (6-17 years) who met the current Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, Text Revision (DMS-IV-TR) criteria for autistic disorder and who also had serious behavioral problems (ie, tantrums, aggression, self-injurious behavior, or a combination of these behavioral problems) between March 2011 and June 2012. In phase 1, single-blind aripiprazole was flexibly dosed (2-15 mg/d) for 13-26 weeks. Patients with a stable response (≥ 25% decrease in Aberrant Behavior Checklist-irritability subscale score and a rating of "much improved" or "very much improved" on the Clinical Global Impressions-Improvement scale) for 12 consecutive weeks were randomized into phase 2 to continue aripiprazole or switch to placebo. Treatment was continued until relapse or up to 16 weeks. The primary end point was time from randomization to relapse. Eighty-five patients were randomized in phase 2. The difference in time to relapse between aripiprazole and placebo was not statistically significant (P = .097). Kaplan-Meier relapse rates at week 16 were 35% for aripiprazole and 52% for placebo (hazard ratio [HR] = 0.57; number needed to treat [NNT] = 6). The most common adverse events during phase 1 were weight increase (25.2%), somnolence (14.8%), and vomiting (14.2%); and, during phase 2 (aripiprazole vs placebo), they were upper respiratory tract infection (10.3% vs 2.3%), constipation (5.1% vs 0%), and movement disorder (5.1% vs 0%). In this study, there was no statistically significant difference between aripiprazole and placebo in time to relapse during maintenance therapy. However, the HR and NNT suggest some patients will benefit from maintenance treatment. Patients receiving aripiprazole should be periodically reassessed to determine the continued need for treatment.

Can oncology recapitulate paleontology? Lessons from species extinctions

PubMed Central

2015-01-01

Although we can treat cancers with cytotoxic chemotherapies, target them with molecules that bind to oncogenic drivers, and induce substantial cell death with radiation, local and metastatic tumours recur, resulting in extensive morbidity and mortality. It is difficult to drive a tumour to extinction. Geographically dispersed species are perhaps equally resistant to extinction, but >99.9% of species that have ever existed have become extinct. By contrast, we are nowhere near that level of success in cancer therapy. The phenomena are broadly analogous. In both cases, a genetically diverse population mutates and evolves through natural selection. The goal of cancer therapy is to cause cancer cell population extinction or at least to limit any further increase in population size, so the tumour burden does not overwhelm the patient. However, despite available treatments, complete responses are rare, and partial responses are limited in duration. Many patients eventually relapse with tumours that evolve from cells that survive therapy. Similarly, species are remarkably resilient to environmental change. Paleontology can show us the conditions that lead to extinction and the characteristics of species that make them resistant to extinction. These lessons could be translated to improve cancer therapy and prognosis. PMID:25687908

Consecutive monitoring of faecal calprotectin during mesalazine suppository therapy for active rectal inflammation in ulcerative colitis.

No studies have monitored the levels of faecal calprotectin (FC) during mesalazine suppository therapy for proctitis in ulcerative colitis (UC). To evaluate the value of consecutive monitoring of FC in patients with UC during mesalazine suppository therapy. One hundred and sixty patients with active inflammation limited to the rectum were treated with mesalazine 1 g suppository once daily for 8 weeks. Patients who achieved clinical remission were advised to maintain the treatment, and were followed up for further 40 weeks. FC levels were measured every 8 weeks during the study. At week 8, 118 patients (74%) went into clinical remission, of whom 88 achieved endoscopic healing. The median FC level significantly decreased in patients with clinical and endoscopic remission (both P < 0.0001), while it did not change significantly in those without remission. Eighty (68%) of the 118 patients with remission continued the treatment. Twenty-four patients (30%) relapsed during the 40-week follow-up. In patients with clinical relapse, the median FC level elevated already 8 weeks before the diagnosis of relapse. In contrast, in patients who maintained remission it remained at a low level and did not significantly change during the follow-up. Elevated FC level (≥55 μg/g) was useful for the early diagnosis of relapse (88% sensitivity and 80% specificity). Faecal calprotectin may represent a useful biomarker for the assessment of disease activity in UC patients treated with mesalazine suppositories. Serial monitoring of faecal calprotectin appears to be valuable for the prediction and early diagnosis of relapse during maintenance therapy. © 2015 John Wiley & Sons Ltd.

Objective: RESTORE was a randomized, partially placebo-controlled exploratory study evaluating multiple sclerosis (MS) disease activity during a 24-week interruption of natalizumab. Methods: Eligible patients were relapse-free through the prior year on natalizumab and had no gadolinium-enhancing lesions on screening brain MRI. Patients were randomized 1:1:2 to continue natalizumab, to switch to placebo, or to receive alternative immunomodulatory therapy (other therapies: IM interferon β-1a [IM IFN-β-1a], glatiramer acetate [GA], or methylprednisolone [MP]). During the 24-week randomized treatment period, patients underwent clinical and MRI assessments every 4 weeks. Results: Patients (n = 175) were randomized to natalizumab (n = 45), placebo (n = 42), or other therapies (n = 88: IM IFN-β-1a, n = 17; GA, n = 17; MP, n = 54). Of 167 patients evaluable for efficacy, 49 (29%) had MRI disease activity recurrence: 0/45 (0%) natalizumab, 19/41 (46%) placebo, 1/14 (7%) IM IFN-β-1a, 8/15 (53%) GA, and 21/52 (40%) MP. Relapse occurred in 4% of natalizumab patients and in 15%–29% of patients in the other treatment arms. MRI disease activity recurred starting at 12 weeks (n = 3 at week 12) while relapses were reported as early as 4–8 weeks (n = 2 in weeks 4–8) after the last natalizumab dose. Overall, 50/167 patients (30%), all in placebo or other-therapies groups, restarted natalizumab early because of disease activity. Conclusions: MRI and clinical disease activity recurred in some patients during natalizumab interruption, despite use of other therapies. Classification of evidence: This study provides Class II evidence that for patients with MS taking natalizumab who are relapse-free for 1 year, stopping natalizumab increases the risk of MS relapse or MRI disease activity as compared with continuing natalizumab.

Despite the success of central nervous system (CNS) directed therapy in pediatric acute lymphoblastic leukemia (ALL), relapse involving the CNS continues to be observed in 5-10% of children when utilizing standard intrathecal prophylactic chemotherapy. While most pediatric ALL treatment protocols mandate regular lumbar punctures (LP) for the intrathecal injection of chemotherapy, the value of routine cytological analysis of cerebrospinal fluid (CSF) during therapy is unknown. Our objective was to assess the diagnostic value of routine CSF analysis during ALL therapy. To allow for at least 10 years of follow up from ALL diagnosis, children (0-18 years) with ALL diagnosed and treated at SickKids, Toronto, Canada between 1994-2004 were studied. Medical records of patients with CNS relapse were examined to determine whether CNS relapse was diagnosed based on cytology of a routinely obtained CSF sample, a CSF sample obtained because of signs and symptoms or a CSF sample obtained after the diagnosis of a bone marrow relapse. Of 494 children treated for ALL, 31 (6.6%) developed a relapse of ALL involving the CNS. Twenty-two had an isolated CNS relapse and nine had a combined bone marrow and CNS relapse. Among patients with isolated CNS relapse, 73% (16/22) were diagnosed based on routine CSF samples obtained from asymptomatic children. Conversely, 89% (8/9) of children with combined bone marrow and CNS relapse presented with symptoms and signs that prompted CSF examination. Routine CSF examination at the time of LP for intrathecal chemotherapy is useful in detecting CNS relapse. © 2014 Wiley Periodicals, Inc.

Although the treatment of acute lymphoblastic leukemia (ALL) has improved significantly over recent decades, failure due to treatment-related toxicities and relapse of the disease still occur in about 20% of patients. This retrospective study included 308 pediatric ALL patients undergoing maintenance therapy and investigated the effects of genetic variants of enzymes involved in the 6-mercaptopurine (6-MP) metabolism and folate pathway on survival and relapse rates. The presence of at least one of the non-functional ITPA alleles (94C>A and/or IVS2+21A>C variant) was associated with longer event-free survival compared to patients with the wild-type ITPA genotype (p = 0.033). Furthermore, patients carrying at least one non-functional ITPA allele were shown to be at a lower risk of suffering early (p = 0.003) and/or bone marrow relapse (p = 0.017). In conclusion, the ITPA genotype may serve as a genetic marker for the improvement of risk stratification and therapy individualization for patients with ALL. PMID:25303517

Potent CD19-directed immunotherapies, such as chimeric antigen receptor T cells (CART) and blinatumomab, have drastically changed the outcome of patients with relapsed/refractory B cell acute lymphoblastic leukemia (B-ALL). However, CD19-negative relapses have emerged as a major problem that is observed in approximately 30% of treated patients. Developing approaches to preventing and treating antigen-loss escapes would therefore represent a vertical advance in the field. Here, we found that in primary patient samples, the IL-3 receptor α chain CD123 was highly expressed on leukemia-initiating cells and CD19-negative blasts in bulk B-ALL at baseline and at relapse after CART19 administration. Using intravital imaging in an antigen-loss CD19-negative relapse xenograft model, we determined that CART123, but not CART19, recognized leukemic blasts, established protracted synapses, and eradicated CD19-negative leukemia, leading to prolonged survival. Furthermore, combining CART19 and CART123 prevented antigen-loss relapses in xenograft models. Finally, we devised a dual CAR-expressing construct that combined CD19- and CD123-mediated T cell activation and demonstrated that it provides superior in vivo activity against B-ALL compared with single-expressing CART or pooled combination CART. In conclusion, these findings indicate that targeting CD19 and CD123 on leukemic blasts represents an effective strategy for treating and preventing antigen-loss relapses occurring after CD19-directed therapies PMID:27571406

Relapse is the major cause of death in patients with acute myeloid leukemia (AML) after allogeneic hematopoietic cell transplantation (HCT). Measurable residual disease (MRD) detected by multiparameter flow cytometry (MFC) before and after HCT is a strong, independent risk factor for relapse. As next-generation sequencing (NGS) is increasingly applied in AML MRD detection, it remains to be determined if NGS can improve prediction of post-HCT relapse. Herein, we investigated pre-HCT MRD detected by MFC and NGS in 59 adult patients with NPM1-mutated AML in morphologic remission; 45 of the 59 had post-HCT MRD determined by MFC and NGS around day 28. Before HCT, MRD detected by MFC was the most significant risk factor for relapse (hazard ratio [HR], 4.63; P < .001), whereas MRD detected only by NGS was not. After HCT, MRD detected by either MFC or NGS was significant risk factor for relapse (HR, 4.96, P = .004 and HR, 4.36, P = .002, respectively). Combining pre- and post-HCT MRD provided the best prediction for relapse (HR, 5.25; P < .001), with a sensitivity at 83%. We conclude that NGS testing of mutated NPM1 post-HCT improves the risk assessment for relapse, whereas pre-HCT MFC testing identifies a subset of high-risk patients in whom additional therapy should be tested.

For almost three decades in many countries azathioprine has been used to treat relapsing-remitting multiple sclerosis. However its efficacy was usually considered marginal and following approval of β interferons for this indication it was no longer recommended as first line treatment, even if presently no conclusive direct β interferon-azathioprine comparison exists. To compare azathioprine efficacy versus the currently available β interferons in relapsing-remitting multiple sclerosis, a multicenter, randomized, controlled, single-blinded, non-inferiority trial was conducted in 30 Italian multiple sclerosis centers. Eligible patients (relapsing-remitting course; ≥2 relapses in the last 2 years) were randomly assigned to azathioprine or β interferons. The primary outcome was annualized relapse rate ratio (RR) over 2 years. Key secondary outcome was number of new brain MRI lesions. Patients (n = 150) were randomized in 2 groups (77 azathioprine, 73 β interferons). At 2 years, clinical evaluation was completed in 127 patients (62 azathioprine, 65 β interferons). Annualized relapse rate was 0.26 (95% Confidence Interval, CI, 0.19–0.37) in the azathioprine and 0.39 (95% CI 0.30–0.51) in the interferon group. Non-inferiority analysis showed that azathioprine was at least as effective as β interferons (relapse RRAZA/IFN 0.67, one-sided 95% CI 0.96; p<0.01). MRI outcomes were analyzed in 97 patients (50 azathioprine and 47 β interferons). Annualized new T2 lesion rate was 0.76 (95% CI 0.61–0.95) in the azathioprine and 0.69 (95% CI 0.54–0.88) in the interferon group. Treatment discontinuations due to adverse events were higher (20.3% vs. 7.8%, p = 0.03) in the azathioprine than in the interferon group, and concentrated within the first months of treatment, whereas in the interferon group discontinuations occurred mainly during the second year. The results of this study indicate that efficacy of azathioprine is not inferior to that of β interferons for patients with relapsing-remitting multiple sclerosis. Considering also the convenience of the oral administration, and the low cost for health service providers, azathioprine may represent an alternative to interferon treatment, while the different side effect profiles of both medications have to be taken into account.

Levels of antibodies against the hepatitis B virus (HBV) core protein (anti-HBc) have been associated with response to nucleos(t)ide analogue and (peg)interferon therapy in patients with chronic HBV infection. We performed a prospective study to determine whether the total serum level of anti-HBc level (immunoglobulins M and G) is associated with clinical relapse after discontinuation of nucleos(t)ide analogue-based therapy. We collected data from patients with chronic HBV infection who discontinued nucleos(t)ide analogue therapy according to pre-specified stopping criteria, recruited from November 2012 through July 2016 at an academic hospital in Guangzhou, China. Patients were followed through February 2017. We performed comprehensive biochemical and virologic tests at every visit, and anti-HBc was quantified for 2 years after treatment cessation (at baseline and weeks 4, 8, 12, 24, 48, and 96). The primary endpoint was clinical relapse, defined as level of HBV DNA >2000 IU/mL and level of alanine aminotransferase more than 2-fold the upper limit of normal-these were also the criteria for retreatment. We followed 100 patients (71% positive for HB e antigen [HBeAg] at the start of nucleos(t)ide analogue therapy, 43% treated with entecavir or tenofovir) for a median of 2.5 years after stopping therapy. Clinical relapse occurred in 39 patients (in 46% of patients at year 4 after discontinuation). High level of anti-HBc at the end of treatment (hazard ratio [HR], 0.31 per log IU/mL; P=.002) and low level of HB surface antigen (HBsAg) at the end of treatment (HR, 1.71 per log IU/mL; P=.032) were associated with a reduced risk of clinical relapse after adjusting for age, start of nucleos(t)ide analogue therapy HBeAg-status, and consolidation therapy duration. At year 4, 21% of patients with anti-HBc levels at the end of treatment ≥1000 IU/mL developed a clinical relapse compared to 85% of patients with levels <100 IU/mL (P<.001). An HBsAg level at the end of treatment ≤100 IU/mL was associated with a reduced risk of relapse (HR 0.30; P=.045). However, 82% of patients had levels of HBsAg above 100 IU/mL; for these patients, level of anti-HBc at the end of treatment could be used to determine the risk of relapse (HR 0.39 per log IU/mL; P=.005). In a median 2.5-year follow-up study of patients with chronic HBV infection who stopped nucleos(t)ide analogue therapy, total serum level of anti-HBc at the end of treatment was associated with risk of clinical relapse. Serum level of anti-HBc might be used to select patients suitable for discontinuing nucleos(t)ide analogue therapy. Copyright © 2018 AGA Institute. Published by Elsevier Inc. All rights reserved.

Our objective was to evaluate the validity of surgery for secondary spontaneous pneumothorax (SSP) by comparison with other treatments or with perioperative results for primary spontaneous pneumothorax (PSP). Between January 2009 and March 2015, 144 patients with SSP, aged 60 years or over, were treated in our institution. We reviewed the patients' characteristics, perioperative results, and relapse rate. Treatment to arrest air-leakage included surgery (n = 79), drainage only (n = 30), and pleurodesis (n = 35), and the pneumothorax relapse rate or mortality before discharge was compared for each. Additionally, we compared the perioperative results or relapse rate between SSP (n = 70) and PSP (n = 70) in patients who underwent 3-port thoracoscopic surgery. There was a significant difference in the relapse rate between the surgery and non-surgery groups (5.3 vs. 27.4 %, p = 0.0006). However, no significant difference in mortality before discharge was determined (p = 0.66). Significant differences were identified between the SSP and PSP groups for operation time, duration of chest drainage, and the length of postoperative hospitalization, and the postoperative morbidity were greater in the SSP group (p < 0.0001 for all). However, there was no significant difference in postoperative 30-day mortality or the relapse rate (p = 0.5, p = 0.68, respectively). Surgical treatment under general anesthesia for SSP is effective for arresting persistent air leaks or avoiding pneumothorax relapse, compared with drainage or pleurodesis, and is feasible if the appropriate perioperative management is performed.

The somatic translocation t(8;21)(q22;q22)/RUNX1-RUNX1T1 is one of the most frequent rearrangements found in children with standard-risk acute myeloid leukemia (AML). Despite the favorable prognostic role of this aberration, we recently observed a higher than expected frequency of relapse. Here, we employed an integrated high-throughput approach aimed at identifying new biological features predicting relapse among 34 t(8;21)-rearranged patients. We found that the DNA methylation status of patients who suffered from relapse was peculiarly different from that of children maintaining complete remission. The epigenetic signature, made up of 337 differentially methylated regions, was then integrated with gene and protein expression profiles, leading to a network, where cell-to-cell adhesion and cell-motility pathways were found to be aberrantly activated in relapsed patients. We identified most of these factors as RUNX1-RUNX1T1 targets, with Ras Homolog Family Member (RHOB) overexpression being the core of this network. We documented how RHOB re-organized the actin cytoskeleton through its downstream ROCK-LIMK-COFILIN axis: this increases blast adhesion by stress fiber formation, and reduces mitochondrial apoptotic cell death after chemotherapy treatment. Altogether, our data show an epigenetic heterogeneity within t(8;21)-rearranged AML patients at diagnosis able to influence the program of the chimeric transcript, promoting blast re-emergence and progression to relapse.

Responders to acute-phase cognitive therapy (A-CT) for major depressive disorder (MDD) often relapse or recur, but continuation-phase cognitive therapy (C-CT) or fluoxetine reduces risks for some patients. We tested composite moderators of C-CT versus fluoxetine's preventive effects to inform continuation treatment selection. Responders to A-CT for MDD judged to be at higher risk for relapse due to unstable or partial remission (N=172) were randomized to 8 months of C-CT or fluoxetine with clinical management and assessed, free from protocol treatment, for 24 additional months. Pre-continuation-treatment characteristics that in survival analyses moderated treatments' effects on relapse over 8 months of continuation-phase treatment (residual symptoms and negative temperament) and on relapse/recurrence over the full observation period's 32 months (residual symptoms and age) were combined to estimate the potential advantage of C-CT versus fluoxetine for individual patients. Assigning patients to optimal continuation treatment (i.e., to C-CT or fluoxetine, depending on patients' pre-continuation-treatment characteristics) resulted in absolute reduction of relapse or recurrence risk by 16-21% compared to the other non-optimal treatment. Although these novel results require replication before clinical application, selecting optimal continuation treatment (i.e., personalizing treatment) for higher risk A-CT responders may decrease risks of MDD relapse and recurrence substantively.

The Canadian Multiple Sclerosis Working Group (CMSWG) developed practical recommendations in 2004 to assist clinicians in optimizing the use of disease-modifying therapies (DMT) in patients with relapsing multiple sclerosis. The CMSWG convened to review how disease activity is assessed, propose a more current approach for assessing suboptimal response, and to suggest a scheme for switching or escalating treatment. Practical criteria for relapses, Expanded Disability Status Scale (EDSS) progression and MRI were developed to classify the clinical level of concern as Low, Medium and High. The group concluded that a change in treatment may be considered in any RRMS patient if there is a high level of concern in any one domain (relapses, progression or MRI), a medium level of concern in any two domains, or a low level of concern in all three domains. These recommendations for assessing treatment response should assist clinicians in making more rational choices in their management of relapsing MS patients.

Foreign bodies are usually detected at the first visit. However, they may be overlooked sometimes, especially in children, and may cause some clinical conditions including unilateral relapsing conjunctivitis. A five-year-old girl was presented to the emergency clinic of our hospital with epiphora, purulent discharge, eyelid swelling, and a foreign body feeling in her right eye. The symptoms had been present for one year, and the patient was treated for relapsing conjunctivitis. In slit lamp examination performed with difficulty because of the patient's lack of cooperation, a localized edema and erythema were observed under the right eyelid. An exploration under general anesthesia was planned, and a 1.5 cm-long subconjunctival grass inflorescence was removed. An unknown subconjunctival foreign body should be considered in each patient with relapsing conjunctivitis, especially in children, even in the absence of ocular trauma.

Clinical stage II/III esophageal cancer (EC), as defined by the Japanese Classification, relapses at a moderately high rate even after curative resection. The number of lymph node metastases is known to be associated with tumor relapse. Recently, the prognostic significance of occult metastatic lymph nodes (MLNs), as well as that of overt MLNs, has been reported. The aim of this study was to investigate the impact of the total number of MLNs including occult MLNs on postoperative relapse in clinical stage II/III EC. One hundred and five patients with clinical stage II/III EC who underwent esophagectomy accompanied by radical lymphadenectomy at the Department of Surgical Oncology in Osaka City University Hospital between January 2000 and October 2008 were included in this study. Occult MLNs, metastases not detected by hematoxylin-eosin staining, were identified by immunohistochemistry (IHC) using antipancytokeratin antibody AE1/AE3. The clinicopathological features of occult MLNs were compared between the relapse and no relapse groups. A total of 6558 lymph nodes (1357 from two-field dissection and 5201 from three-field dissection) were examined by IHC staining; 362 overt MLNs and 143 occult MLNs were detected. The number of occult MLNs increased in proportion to the International Union Against Cancer pathological (p)N-status and pStage. When the number of occult MLNs was added to the number of pNs, the number of total MLNs was associated with postoperative relapse. With respect to tumor, node, metastasis stage, 6 of 22 patients (27%) who were pathological node-negative converted to node-positive by considering total MLNs. The number of N3 patients with relapse increased markedly with restaging by total MLNs. The number of total MLNs, but not overt MLNs, was an independent prognostic factor on multivariate analysis. These results suggest that occult MLNs were often found, and they were associated with postoperative relapse of resectable esophageal cancer. The total number of MLNs including occult MLNs could contribute to evaluating the precise stage of patients with esophageal cancer. © 2013 Wiley Periodicals, Inc. and the International Society for Diseases of the Esophagus.

Long-Term Skeletal Changes After Maxillary Distraction Osteogenesis in Growing Children With Cleft Lip/Palate.

To systematically evaluate the skeletal changes after maxillary distraction osteogenesis (DO) in growing patients with cleft lip with or without cleft palate (CL/P). Electronic databases, gray literature, and reference list searches were conducted. Articles reporting prospective and retrospective studies that included patients <16 years old (N ≥ 6) who had received DO surgery for correction of a midfacial hypoplasia due to CL/P, and the period of follow-up persisted >1 year were reviewed. The original articles were evaluated by 2 investigators to ensure that they met the selection criteria. A methodologic quality assessment tool was used to evaluate the quality of selected studies. Twenty-six studies met the initial search criteria, and 9 articles included 101 growing patients with maxillary hypoplasia due to CL/P who received DO surgery were finally selected and analyzed. The results showed that long term after maxillary advancement with DO, the horizontal relapse in A-point was <15% in 3 studies, 20% to 25% in 1 study, 30% to 35% in 3 studies, and >40% in 1 study. Totally, the range of horizontal relapse in A-point was 11.9% to 45.9%. Similarly, the relapse in SNA angle was <30% in 1 study, 30% to 40% in 3 studies, and >40% in 2 studies. Totally, the range of relapse in SNA was 25.7% to 77%. Two studies showed that the vertical relapse in A-point were 137% and 208%, and in the PNS point were 65% and 62.7%. Although findings demonstrated that DO is an effective treatment method for severe maxillary hypoplasia in growing patients with CL/P, there is a relatively high amount of skeletal relapse both in horizontal and vertical dimension. Thus, the first proposed alternative for CL/P patients would be to select the correct primary procedure to decrease damage and avoid unnecessary scars. Then appropriate preoperative and postoperative care is necessary to prevent postoperative relapse. In addition, overcorrection also may be a possible alternative for compensation of postoperative relapse.

There is a debate regarding the management of ovarian immature teratomas (ITs). In adult women, postoperative chemotherapy is standard except for stage I, grade 1 disease, whereas surgery alone is standard in pediatric patients. To determine the role of chemotherapy, a pooled analysis of pediatric and adult clinical trials was conducted. Data from 7 pediatric trials and 2 adult trials were merged in the Malignant Germ Cell International Collaborative data set. Four trials included patients with newly diagnosed pure ovarian ITs and were selected (Pediatric Oncology Group/Children's Cancer Group Intergroup Study (INT 0106), Second UKCCSG Germ Cell Tumor Study (GC2), Gynecologic Oncology Group (GOG 0078 and GOG 0090). Adult and pediatric trials were analyzed separately. The primary outcome measures were event-free survival (EFS) and overall survival (OS). One hundred seventy-nine patients were included (98 pediatric patients and 81 adult patients). Ninety pediatric patients were treated with surgery alone, whereas all adult patients received chemotherapy. The 5-year EFS and OS were 91% and 99%, respectively, for the pediatric cohort and 87% and 93%, respectively, for the adults. There were no relapses in grade 1 patients, regardless of the stage or age. Only 1 adult patient with a grade 2 IT relapsed. Among grade 3 patients, the 5-year EFS was 0.92 (0.72-0.98) for stage I/II and 0.52 (0.22-0.75) for stage III in the pediatric cohort (P = .005) and 0.91 (0.69-0.98) for stage I/II and 0.65 (0.39-0.83) for stage III/IV in the adult cohort (P = .01). Postoperative chemotherapy did not decrease relapses in the pediatric cohort. The grade was the most important risk factor for relapse in ovarian ITs. Among grade 3 patients, the stage was significantly associated with relapse. Adjuvant chemotherapy did not decrease relapses in the pediatric cohort; its role in adults remains unresolved.

We retrospectively analyzed 81 relapsed or refractory adult T-cell leukemia-lymphoma (ATL) patients who received salvage therapy in our institution between 2000 and 2010. These patients had received chemotherapy, radiation, or hematopoietic stem cell transplantation (HSCT) as an initial treatment, and were then given chemotherapy, radiation, HSCT, or donor lymphocyte infusion (DLI) as salvage therapy. Median survival time was 3.9 months. Of 5 long-term survivors, who survived more than 2 years after the first salvage therapy, 4 patients received HSCT or DLI, and the other was given mogamulizumab as the salvage therapy. For patients with relapsed or refractory ATL, HSCT/DLI is a promising treatment for achieving long-term survival. Mogamulizumab may be the good choice for those who are ineligible for HSCT.

Cost effectiveness and budget impact of natalizumab in patients with relapsing multiple sclerosis.

Disease-modifying therapy (DMT) is the largest single-cost item that contributes to the total per-patient cost of multiple sclerosis (MS), a disabling disorder of the central nervous system. Natalizumab is the most recent DMT to be approved for the treatment of relapsing MS and may be an attractive alternative to interferon beta and glatiramer acetate (GA). To determine from the perspective of a United States payer (1) the incremental cost effectiveness of natalizumab compared with other DMTs and (2) the budgetary impact of utilization of natalizumab for the treatment of relapsing MS. A combined cost effectiveness and budget impact model was developed. Model inputs were drug acquisition costs (wholesale acquisition cost), costs of drug administration and monitoring, costs of treating relapses, anticipated reduction in relapse rates after 2 years of therapy, and estimated market utilization of natalizumab. Outcomes included total 2-year costs of therapy per patient, costs per relapse avoided for each treatment, and overall 2-year costs to the health plan and per member per month (PMPM) costs. Drug acquisition costs are in 2008 US dollars, and all other costs were inflated to 2008 US dollars when necessary. Univariate sensitivity analyses were performed to determine the model inputs with the greatest influence on the cost per relapse avoided for natalizumab. The overall 2-year cost of therapy per patient was $72,120 for natalizumab, $56,790 for intramuscular (IM) interferon beta-1a (IFNbeta-1a), $56,773 for IFNbeta-1b, $57,180 for GA, and $58,538 for subcutaneous (SC) IFNbeta-1a. The cost per relapse avoided was lowest for natalizumab at $56,594, followed by $87,791 for IFNbeta-1b, $93,306 for IM IFNbeta-1a, $96,178 for SC IFNbeta-1a, and $103,665 for GA. The incremental cost-effectiveness ratios of natalizumab relative to IM IFNbeta-1a, IFNbeta-1b, GA, and SC IFNbeta-1a were $23,029, $24,452, $20,671, and $20,403 per additional relapse avoided, respectively. An increase in natalizumab utilization to 9% resulted in an increase of approximately $61 760 in total 2-year costs to a hypothetical health plan of 1 million members, or a $0.003 PMPM incremental cost. Univariate sensitivity analyses indicated that the model inputs with the most influence on cost per relapse avoided for natalizumab were the weighted average number of relapses before treatment and the anticipated relative relapse rate reduction. Natalizumab was the most cost-effective therapy as measured by total cost per relapse avoided, not withstanding a higher drug acquisition cost versus other DMTs. Entry of natalizumab to the market is likely to result in a minimal increase in health-plan costs on a PMPM basis. Limitations of the study include the use of a surrogate measure, relapse avoided, as an outcome measure; also, adverse events were not included in the model.

Anti-gamma-aminobutyric acid B (anti-GABA B ) receptor encephalitis is a newly described type of autoimmune encephalitis. We report a case series of patients diagnosed with anti-GABA B receptor encephalitis in China, focusing on their presentations, laboratory and imaging results, and outcomes, as well as the treatment strategies which were employed. Data from patients diagnosed with anti-GABA B receptor encephalitis in the Second Affiliated Hospital, School of Medicine, Zhejiang University, from January 2014 to June 2015 were retrospectively collected and analyzed. Based on specific diagnostic criteria, seven cases were included. Six of the seven patients were males, and a median age at presentation of 56 years (range: 4-71 years). Seizures were the most common initial symptom, and all patients developed symptoms of typical limbic encephalitis during their disease course. Additional types of autoantibodies were identified in four patients. After presentation, three patients were found to have small cell lung cancer and one patient was eventually diagnosed with thymoma. All patients accepted first-line immune therapy, but only one chose tumor treatment. The three tumor-free patients had a good outcome, whereas those with tumors had a poor one. Finally, there were no relapses during follow-up. Anti-GABA B receptor encephalitis is a rare, unique autoimmune disease, and is often associated with tumors. It should be considered in the differential diagnosis for middle and senior-aged patients who present with predominantly limbic encephalitis symptoms. Importantly, earlier recognition of this potentially treatable condition could improve its overall prognosis.

The purpose was to report the effects of delayed-release dimethyl fumarate (DMF; also known as gastro-resistant DMF) on the number of relapses requiring intravenous (IV) steroids and multiple sclerosis (MS)-related hospitalizations using integrated data from the Phase III DEFINE and CONFIRM studies. DEFINE and CONFIRM were randomized, double-blind, placebo-controlled, multicenter studies that evaluated the efficacy and safety of DMF over a 2-year period in patients with relapsing-remitting MS (RRMS). Patients were randomized (1:1:1) to receive oral DMF 240 mg BID or TID, placebo, or glatiramer acetate (CONFIRM only). Eligible subjects (aged 18-55 years) had an EDSS score of 0-5.0 and experienced either ≥1 relapse in the 12 months or had ≥1 gadolinium-enhanced lesion on brain MRI in the 6 weeks, before randomization. Data DEFINE and CONFIRM were pooled and analyzed using a negative binomial regression model (adjusted for study and region). Data obtained after subjects switched to an alternative MS therapy were not included in the analysis. Only relapses confirmed by the Independent Neurology Evaluation Committee were included in the analysis of relapses requiring IV steroids. The study population (intention-to-treat) comprised 2301 patients who received either placebo (n = 771), DMF BID (n = 769), or DMF TID (n = 761). Baseline demographic and disease characteristics were generally well balanced among treatment groups. Throughout the 2-year studies, the total number of relapses treated with methylprednisolone was 402, 221, and 209 in the placebo, DMF BID, and DMF TID groups, respectively. A smaller proportion of patients in the DMF BID (168 of 769 [21.8%]) and DMF TID (151 of 761 [19.8%]) groups experienced ≥1 relapse requiring IV steroids compared with the placebo group (284 of 771 [36.8%]). The total number of MS-related hospitalizations over 2 years was 136, 94, and 74 in the placebo, DMF BID, and DMF TID groups. A smaller proportion of patients in the DMF BID (73 of 769 [9.5%]) and DMF TID (57 of 761 [7.5%]) groups had ≥1 MS-related hospitalization compared with the placebo group (104 of 771 [13.5%]). DMF is an effective and well tolerated therapy for RRMS. In addition to clinical benefits, the use of DMF may be associated with reduced patient burden and health economic savings, resulting from a decrease in resource utilization associated with relapses.

Adults with relapsed/refractory acute lymphoblastic leukemia have an unfavourable prognosis, which is influenced by disease and patient characteristics. To further evaluate these characteristics, a retrospective analysis of 1,706 adult patients with Ph-negative relapsed/refractory B-precursor acute lymphoblastic leukemia diagnosed between 1990–2013 was conducted using data reflecting the standard of care from 11 study groups and large centers in Europe and the United States. Outcomes included complete remission, overall survival, and realization of stem cell transplantation after salvage treatment. The overall complete remission rate after first salvage was 40%, ranging from 35%–41% across disease status categories (primary refractory, relapsed with or without prior transplant), and was lower after second (21%) and third or greater (11%) salvage. The overall complete remission rate was higher for patients diagnosed from 2005 onward (45%, 95% CI: 39%–50%). One- and three-year survival rates after first, second, and third or greater salvage were 26% and 11%, 18% and 6%, and 15% and 4%, respectively, and rates were 2%–5% higher among patients diagnosed from 2005. Prognostic factors included younger age, longer duration of first remission, and lower white blood cell counts at primary diagnosis. This large dataset can provide detailed reference outcomes for patients with relapsed/refractory Ph-negative B-precursor acute lymphoblastic leukemia. clinicaltrials.gov identifier: 02003612 PMID:27587380

Background Thrombotic thrombocytopenic purpura and the hemolytic uremic syndrome (TTP-HUS) are related and uncommon disorders with a high fatality and complication rate if untreated. Plasma exchange therapy has been shown to produce high response rates and improve survival in patients with many forms of TTP-HUS. We performed a retrospective cohort study of 178 consecutively treated patients with TTP-HUS and analyzed whether clinical or laboratory characteristics could predict for important short- and long-term outcome measures. Results Overall 30-day mortality was 16% (n = 27). 171 patients (96%) received plasma exchange as the principal treatment, with a mean of 8 exchanges and a mean cumulative infused volume of 42 ± 71 L of fresh frozen plasma. The rate of complete response was 65% or 55% depending on whether this was defined by a platelet count of 100,000/μl or 150,000/μl, respectively. The rate of relapse was 18%. The Clinical Severity Score did not predict for 30-day mortality or relapse. The time to complete response did not predict for relapse. Renal insufficiency at presentation was associated with a decreased risk of relapse, with each unit increase in serum creatinine associated with a 40% decreased odds of relapse. 72% of our cohort had an idiopathic TTP-sporadic HUS, while 17% had an underlying cancer, received a solid organ transplant or were treated with a mitomycin-based therapy. The estimated overall 5-year survival was 55% and was significantly better in those without serious underlying conditions. Conclusion Plasma exchange therapy produced both high response and survival rates in this large cohort of patients with TTP-HUS. The Clinical Severity Score did not predict for 30-day mortality or relapse, contrary to our previous findings. Interestingly, the presence of renal insufficiency was associated with a decreased risk of relapse. The most important predictor of mortality was the presence or absence of a serious underlying disorder. PMID:19046460

Relapse is a typical feature of heroin addiction and rooted in genetic and psychological determinants. The aim of this study was to evaluate the effect of personality traits, impulsivity, and COMT gene polymorphism (rs4680) on relapse to heroin use during 5-year follow up. 564 heroin dependent patients were enrolled in compulsory drug rehabilitation center. 12 months prior to their release, personality traits were measured by BIS-11 (Barratt Impulsiveness Scale-11) and Temperament and Character Inventory (TCI). The COMT gene rs4680 polymorphism was genotyped using a DNA sequence detection system. The heroin use status was evaluated for 5 years after discharged. Among the 564 heroin-dependent patients, 500 were followed for 5 years after discharge and 53.0% (n = 265) were considered as relapsed to heroin use according to a strict monitor system. Univariate analysis showed that age, having ever been in methadone maintenance treatment (MMT), the total scores and non-planning scores of BIS-11, and the COMT rs4680 gene variants were different between relapse and abstinent groups. Logistic regression analysis showed higher BIS total score, having ever been in MMT and younger first heroin use age are the predictors of relapse to heroin use during 5 years follow-up, and the COMT rs4680 gene had an interaction with BIS scores. Our findings indicated that the impulsive personality traits, methadone use history, and onset age could predict relapse in heroin-dependent patients during 5 year's follow up. The COMT gene showed a moderational effect in part the relationship of impulsivity with heroin relapse. © 2015 Wiley Periodicals, Inc.

A significant portion of patients treated for pediatric acute lymphoblastic leukemia (ALL) relapse. We hypothesized that common polymorphisms with moderate effect sizes and large attributive risks could explain an important fraction of ALL relapses. Methylenetetrahydrofolate reductase (MTHFR) is central to folate metabolism and has two common functional polymorphisms (C677T and A1298G). Methotrexate (MTX), which interrupts folate metabolism, is a mainstay of pediatric ALL therapy. MTX inhibits the synthesis of dTMP needed for DNA replication by blocking the conversion of 5,10-methylenetetrahydrofolate to 5-methyltetrahydrofolate by MTHFR. We hypothesized that a deactivating MTHFR allele would increase ALL relapse risk by potentially increasing 5,10-methylenetetrahydrofolate and dTMP, enhancing DNA synthesis and thus opposing MTX. To test this hypothesis, we genotyped 520 patients on the Children's Cancer Study Group ALL study, CCG-1891. The MTHFR C677T variant allele was statistically significantly associated with relapse (chi2 = 4.38, P = 0.036). This association remained significant (hazard ratio = 1.82, P = 0.008), controlling for important covariates, and was more predictive of relapse than other predictors, including day 7 bone marrow response. The MTHFR C677T variant allele was not associated with an increased risk of toxicity or infection. The MTHFR A1298G polymorphism was not associated with altered risks of relapse, toxicity, or infection. Haplotype analysis showed six common haplotypes that did not provide additional information predictive for relapse. These data provide evidence that the MTHFR C677T polymorphism is a common genetic variant conferring a moderate relative risk and a high attributable risk for relapse in pediatric ALL patients.

The relapsing nature of melasma emphasizes the need to maintain efficacy achieved after acute treatment. To compare clinical efficacy and safety of two 6-month Triple Combination (TC; containing fluocinolone acetonide, hydroquinone and tretinoin) maintenance regimens in subjects with moderate to severe melasma, after daily treatment up to 8 weeks. This randomized, investigator-blinded, controlled study had a maintenance phase of 6 months. Sixteen centres in Brazil and Mexico enrolled 242 subjects 18 years or older attaining no or mild melasma after 8 weeks of daily TC applications. Subjects were randomized to receive TC in a twice weekly or tapering regimen [3/week (1st month), 2/week (2nd month), 1/week (4th month)]. Efficacy and safety measurements included median time to relapse and relapse-free rate, Global Severity Score, Melasma Area and Severity Index score (MASI), subject's assessment, quality of life questionnaire (MelasQol), and adverse events. The majority (78.8%) had no or mild melasma (GSS ≤ 1) at week 8 and entered maintenance phase. After 6 months, 53% of patients remained relapse-free with improved quality of life, and time to relapse was similar between groups (about 190 days). Melasma severity at study entry, not maintenance baseline, influenced relapse rate. The twice weekly regimen tended to show better effectiveness in postponing relapse in severe melasma. Both regimens were safe. After resolution of melasma with TC, maintenance therapy over 6 months was successful in preventing relapse in over half of the patients who entered maintenance phase. Prescribing medicines should be adapted to patients based on melasma severity. © 2011 The Authors.

Magnetic resonance imaging (MRI) is routinely obtained in patients with central nervous system (CNS) tumors, but few studies have been conducted to evaluate this practice. We assessed the benefits of surveillance MRI and more specifically spine MRI in a contemporary cohort. We evaluated MRI results of children diagnosed with CNS tumors from January 2000 to December 2011. Children with at least one surveillance MRI following the diagnosis of medulloblastoma (MB), atypical teratoid rhabdoid tumor (ATRT), pineoblastoma (PB), supratentorial primitive neuroectodermal tumor, supratentorial high-grade glioma (World Health Organization grade III-IV), CNS germ cell tumors or ependymoma were included. A total of 2,707 brain and 1,280 spine MRI scans were obtained in 258 patients. 97% of all relapses occurred in the brain and 3% were isolated to the spine. Relapse was identified in 226 (8%) brain and 48 (4%) spine MRI scans. The overall rate of detecting isolated spinal relapse was 9/1,000 and 7/1,000 for MB patients. MRI performed for PB showed the highest rate for detecting isolated spinal recurrence with 49/1,000. No initial isolated spinal relapse was identified in patients with glioma, supratentorial primitive neuroectodermal tumor and ATRT. Isolated spinal recurrences are infrequent in children with malignant CNS tumors and the yield of spine MRI is very low. Tailoring surveillance spine MRI to patients with higher spinal relapse risk such as PB, MB with metastatic disease and within 3 years of diagnosis could improve allocation of resources without compromising patient care.

To evaluate the long-term impact of a brief pharmacist intervention (PI) compared with usual care (UC) on prevention of depression relapse. randomised controlled clinical trial Primary Care Of the 179 depressed patients initiating antidepressants, the 113 whose clinical symptoms had remitted (main definition) at 6 months assessment were selected for this secondary study (PI=58; UC=55). PI was an interview to promote medication adherence when patients get antidepressants from pharmacy. Baseline, 3 months, and six-months follow-up assessments were made. The severity of depressive symptoms was evaluated with PHQ9. Patients presenting a remission of symptoms were selected. The patient medical records were reviewed to identify a relapse in the following 12 months by using 4 indicators. There was a lower proportion of patients that relapsed in the PI group than in the UC group 18 months after initiation of treatment, but the difference was not statistically significant either in the intent-to-treat analysis (OR=0.734 [95%CI; 0.273-1.975]) or the per-protocol analysis (OR=0.615 [95%CI; 0.183 -2.060]). All the sensitivity analyses showed consistent results. The sample size and adherence to the protocol in the intervention group were low. PI group showed a non-statistically significant tendency towards presenting fewer relapses. This could be related to the improvement in adherence among patients that received the intervention.

This named patient program evaluated the safety and efficacy of ibrutinib, a selective inhibitor of Bruton's tyrosine kinase in Indian patients with relapsed/refractory chronic lymphocytic leukemia (CLL, with/without chromosome 17 deletion [del17p]) and mantle cell lymphoma (MCL). The eight enrolled patients (relapsed/refractory CLL: n = 6 [4/6 patients with del17p] and relapsed/refractory MCL: n = 2) had median age of 55 years (range, 52-60) and had received a median of 3 (CLL patients) and 4 (MCL patients) prior therapies. Patients received once-daily dose of ibrutinib (420 mg: CLL, 560 mg: MCL). In CLL patients, the median time to response was 3 months (range, 0.5-7) and five of six patients had partial response (PR) whereas one achieved complete response (CR). Median time on treatment was 11.5 months (range, 8-14); five patients continued treatment and one was recommended stem cell transplantation (SCT). Of the two MCL patients, one achieved PR and one showed CR and advanced to SCT. In CLL patients, the median (range) hemoglobin level improved from 9.8 g/dL (7.2-11) at baseline to 12.0 g/dL (9.5-13.2) and median (range) platelet count improved from 150,000 cells/μL (21,000-195,000) at baseline to 190,350 cells/μL (130,000-394,000) at the time of analysis (July 2016). Most adverse events (AEs) reported were infections ( n = 2). No Grade 3-4 or serious AEs, dose reductions, or treatment discontinuation due to AEs were reported. In this first real-world experience in Indian patients, ibrutinib demonstrated therapeutic efficacy in relapsed/refractory CLL (with/without del17p) and MCL. Safety results were consistent with the current known profile of ibrutinib.

Relapsing polychondritis (RP) is a rare autoimmune disorder, and myelodysplastic syndrome (MDS) is accompanied by RP at variable rates. Herein, we report a case with RP and MDS who responded dramatically to 5-azacitidine for MDS. With conventional immunosuppressive treatment, our patient had several episodes of different side effects, including infections. With the diagnosis of MDS and initiation of azacitidine treatment, all the manifestations of RP disappeared, and remission was achieved for MDS. Although he had relapses of either RP or MDS after several years of azacitidine treatment, all relapses were controlled well with the initiation of azacitidine treatment every time. Azacitidine should be kept in mind as a treatment option for RP patients with MDS.

Extramedullary plasmacytoma of the head and neck region (EMPHN) is an uncommon malignant plasma cell neoplasm. In this study we conducted a retrospective analysis of our experience of EMPHN with particular emphasis on the role of definitive radiotherapy. From 1982 to 2001, 10 patients (6 males, 4 females) with EMPHN were treated in our institution. Of nine patients treated at initial diagnosis, all received definitive radiotherapy. One patient treated at relapse underwent surgical resection followed by post-operative radiotherapy. The median age at diagnosis was 55 years (range 35-84 years). The disease was most frequently localized in the paranasal sinuses (50%). All nine patients who received definitive radiotherapy at a dose of 40-50 Gy achieved a complete response. The median follow up period was 29 months (range 7-67 months). Four patients (40%) relapsed, three have died of their disease. Two patients (20%) with paranasal sinus disease subsequently relapsed with multiple myeloma at 10 months and 24 months, respectively. Our results indicate that treatment of EMPHN with radiotherapy achieves excellent rates of local control. The relapse rate in neck nodes of 10% does not justify elective irradiation of the uninvolved neck.

[Tuberculosis recurrence and its risk factors].

The persistence of tuberculosis bacilli in patients who are cured, thus causing recurrence, is an important issue. This case-control study investigated individual and institutional risk factors for relapse by analyzing independent variables related to the patient, the use of antituberculosis drugs, and the service delivered at health care institutions; 56 cases and 105 controls were interviewed. Recurrence was defined as a new tuberculosis episode after the patient had been successfully treated. Controls were selected from among patients who were treated and cured of pulmonary tuberculosis and who did not experience a relapse. Regression models were proposed to control confounding factors or effect modifiers. The variables identified as risk factors for relapse were those related to erratic patient behavior (missing medical appointments and therefore not picking up the medication, not taking the medication, taking the wrong dosage), age, and stress from life events; adverse reactions to antituberculosis drugs; and problems in the organization of health care services that resulted in patients receiving insufficient dosages or amounts of antituberculosis drugs. Receiving information regarding treatment duration provided protection against recurrence. The knowledge regarding these risk factors should result in more intensive follow-up and in more use of directly observed treatment of tuberculosis in order to prevent relapse.

There Is a Method to the Madness: Strategies to Study Host Complement Evasion by Lyme Disease and Relapsing Fever Spirochetes.

PubMed

Marcinkiewicz, Ashley L; Kraiczy, Peter; Lin, Yi-Pin

2017-01-01

Lyme disease and relapsing fever are caused by various Borrelia species. Lyme disease borreliae , the most common vector-borne pathogens in both the U.S. and Europe, are transmitted by Ixodes ticks and disseminate from the site of tick bites to tissues leading to erythema migrans skin rash, arthritis, carditis, and neuroborreliosis. Relapsing fever borreliae , carried by ticks and lice, trigger reoccurring fever episodes. Following transmission, spirochetes survive in the blood to induce bacteremia at the early stages of infection, which is thought to promote evasion of the host complement system. The complement system acts as an important innate immune defense mechanism in humans and vertebrates. Upon activation, the cleaved complement components form complexes on the pathogen surface to eventually promote bacteriolysis. The complement system is negatively modulated by a number of functionally diverse regulators to avoid tissue damage. To evade and inhibit the complement system, spirochetes are capable of binding complement components and regulators. Complement inhibition results in bacterial survival in serum (serum resistance) and is thought to promote bloodstream survival, which facilitates spirochete dissemination and disease manifestations. In this review, we discuss current methodologies to elucidate the mechanisms of Borrelia spp. that promote serum resistance and bloodstream survival, as well as novel methods to study factors responsible for bloodstream survival of Lyme disease borreliae that can be applied to relapsing fever borreliae . Understanding the mechanisms these pathogens utilize to evade the complement system will ultimately aid in the development of novel therapeutic strategies and disease prevention to improve human health.

Retinoic acid (RA) and arsenic target the t(15;17)(q24;q21) PML/RARA driver of acute promyelocytic leukemia (APL), their combination now curing over 95% patients. We report exome sequencing of 64 matched samples collected from patients at initial diagnosis, during remission, and following relapse after historical combined RA-chemotherapy treatments. A first subgroup presents a high incidence of additional oncogenic mutations disrupting key epigenetic or transcriptional regulators (primarily WT1) or activating MAPK signaling at diagnosis. Relapses retain these cooperating oncogenes and exhibit additional oncogenic alterations and/or mutations impeding therapy response (RARA, NT5C2). The second group primarily exhibits FLT3 activation at diagnosis, which is lost upon relapse together with most other passenger mutations, implying that these relapses derive from ancestral pre-leukemic PML/RARA-expressing cells that survived RA/chemotherapy. Accordingly, clonogenic activity of PML/RARA-immortalized progenitors ex vivo is only transiently affected by RA, but selectively abrogated by arsenic. Our studies stress the role of cooperating oncogenes in direct relapses and suggest that targeting pre-leukemic cells by arsenic contributes to its clinical efficacy.
