Multiple myeloma is the second most common hematologic malignancy. Chromosomal aberrations are important prognostic determinants that influence the clinical decision-making in newly-diagnosed multiple myeloma (NDMM). Patients are considered high-risk if any of the following features are detected: hypodiploidy, deletion 13 by cytogenetics, t(4;14), t(14;16), t(14;20) and/or 17 p deletion. In the absence of these features patients are considered standard risk. Outside of trials, risk-adapted therapy in the transplant-eligible high-risk patients advocates use of bortezomib-based induction therapy followed by autologous stem cell transplantation (ASCT) and bortezomib-based maintenance therapy. High-risk, transplant-ineligible patients should also utilize bortezomib as initial therapy since it is known to overcome the poor prognosis associated with some high-risk features. The goal of therapy in high-risk patients is to attain and maintain a state of complete remission as much as possible. In contrast, the standard-risk, transplant-eligible patients may be treated with either lenalidomide-dexamethasone or bortezomib-based therapy followed by ASCT. In such patients, ASCT can also be deferred until first relapse if the patients are tolerating initial therapy well. Lenalidomide maintenance therapy in the post-transplant setting in standard-risk patients is controversial and not recommended routinely. For transplant-ineligible standard-risk patients, multiple options exist, although in the absence direct comparisons, we prefer lenalidomide plus low-dose dexamethasone over melphalan-based combinations. This review outlines evidence-based management approaches in NDMM, with a focus on risk-adapted therapy.

To assess the efficacy of pegaptanib as maintenance therapy in neovascular age-related macular degeneration (NV-AMD) patients after induction therapy. A phase IV, prospective, open-label, uncontrolled exploratory study including subjects with subfoveal NV-AMD who had had one to three induction treatments 30-120 days before entry and showed investigator-determined clinical/anatomical NV-AMD improvement. Lesions in the study eye were: any subtype, 12 or fewer disc areas; postinduction centre point thickness (CPT) 275 μm or less or thinning of 100 μm or more (optical coherence tomography); visual acuity (VA) 20/20-20/400. Intravitreal pegaptanib 0.3 mg was administered as maintenance every 6 weeks for 48 weeks with follow-up to week 54. Booster treatment additional unscheduled treatment for wet age-related macular degeneration, was allowed in the study eye at the investigators' discretion for clinical deterioration. Of 568 enrolled subjects, 86% completed 1 year of pegaptanib. Mean VA improvement during induction (49.6 to 65.5 letters) was well preserved (54-week mean 61.8 letters). Mean CPT was relatively stable during maintenance (20 μm increase during the study). Fifty per cent did not receive unscheduled booster treatment to week 54; 46% did have one such booster (mean 147 days after maintenance initiation). An induction-maintenance strategy, using non-selective then selective vascular endothelial growth factor (VEGF) inhibitors, could be considered for NV-AMD. This approach may have particular relevance for patients with systemic comorbidities who require long-term anti-VEGF therapy for NV-AMD.

Percutaneous tibial nerve stimulation is an effective second line therapy for lower urinary tract symptoms. Data on percutaneous tibial nerve stimulation maintenance treatment are scarce. In this study we evaluate its effectiveness and propose an algorithm of percutaneous tibial nerve stimulation maintenance treatment in patients with multiple sclerosis. In this prospective, multicenter, open label trial consecutive patients with multiple sclerosis and lower urinary tract symptoms unresponsive to medical therapy were treated with 12 weekly sessions of percutaneous tibial nerve stimulation. Responder patients (50% or greater improvement of lower urinary tract symptoms as measured by the patient perception of bladder condition questionnaire) entered a maintenance phase with individualized treatment frequency based on patient response. Lower urinary tract symptoms were assessed using a 3-day frequency volume chart, urodynamics and patient perception of bladder condition questionnaire. Treatment satisfaction was evaluated using a global response assessment scale and a treatment satisfaction visual analog scale. A total of 83 patients were included in the study and 74 (89%) responded to initial treatment. Persistent efficacy occurred in all initial responders after a mean treatment of 24 months. The greatest frequency of maintenance percutaneous tibial nerve stimulation was every 2 weeks. Lower urinary tract symptoms and patient treatment satisfaction improved with time compared to initial treatment (p <0.05). Bladder diary parameters and voiding parameters improved compared to baseline (p <0.05). Prolonged percutaneous tibial nerve stimulation treatment leads to a persistent improvement of lower urinary tract symptoms in patients with multiple sclerosis.

Relative costs and utilization-related outcomes of a fluticasone propionate 250 μg + salmeterol 50 μg combination (FSC), tiotropium bromide, and ipratropium as initial maintenance therapy in COPD have not been compared in a commercially-insured population. This retrospective, observational cohort study used health care claims data from January 2004 to June 2009 from a large administrative database for patients aged ≥40 years with COPD. Time-to-first COPD-related health care event beginning 30 days following therapy initiation with FSC (n = 16,684), ipratropium alone or in fixed dose combination with albuterol (n = 14,449), or tiotropium (n = 12,659) was estimated using Cox proportional hazard models that controlled for differences in patient demographic characteristics, health care utilization, and comorbidities at baseline. Mean adjusted costs and numbers of COPD-related health care encounters and prescription medication fills were compared among patients with 12 months of follow-up (FSC, n = 12,595; ipratropium, n = 10,617; tiotropium, n = 9126). With FSC as the reference, risk for a COPD-related hospitalization and/or emergency department visit was significantly higher for ipratropium (hazard ratio [HR] 1.64, 95% confidence interval [CI] 1.50-1.79) and tiotropium (HR 1.29, CI 1.17-1.41). Mean adjusted 12-month COPD-related total health care costs were lower for FSC ($2068, standard deviation [SD] $1190) than for ipratropium ($2841, SD $1858) and tiotropium ($2408, SD $1511, both P <0.05). Mean number of COPD-related hospitalizations, emergency department visits, and outpatient visits associated with an oral corticosteroid or antibiotic were also lower for FSC than for ipratropium and tiotropium (all P <0.05). In this retrospective "real-world" observational sample of COPD patients, initiating treatment with FSC was associated with significantly better clinical and economic outcomes compared with short- and long-acting anticholinergic therapy. Consistent with the goal of preventing and reducing exacerbations advocated by global guidelines, the findings suggest that initiation of maintenance treatment with FSC may afford clinical benefits at a lower cost than anticholinergic treatment.

We report the first randomized prospective comparative study of long-term maintenance ganciclovir (9-[2-hydroxy-1-(hydroxymethyl)ethoxymethyl]guanine, BW759U, DHPG) therapy for cytomegalovirus retinitis in patients with the acquired immunodeficiency syndrome (AIDS). Eleven retinitis patients who received a 10-day course of ganciclovir induction therapy and then were randomized to receive either immediate daily ganciclovir maintenance therapy or deferred maintenance (eight deferred maintenance, three immediate maintenance) were evaluated for drug efficacy. Median time to retinitis progression was 42 days for the immediate maintenance group compared with 16 days for the deferred maintenance group, (P = 0.07). After crossing over to maintenance therapy, patients in the deferred group had a median time to retinitis progression of 58 days compared to 16 days while not on maintenance therapy (P = 0.13). Only 9% of cultures obtained while patients received maintenance therapy were positive for cytomegalovirus, vs 40% of those obtained off maintenance (P less than 0.001). We can state then that maintenance therapy with ganciclovir delays, but does not halt, progression of cytomegalovirus retinitis and suppresses, but does not eradicate, cytomegalovirus shedding in patients with AIDS.

Incarcerated people living with HIV and opioid dependence face enormous challenges to accessing evidence-based treatment during incarceration and after release into the community, placing them at risk of poor HIV treatment outcomes, relapse to opioid use and accompanying HIV transmission risk behaviors. Here we describe in detail the design and implementation of Project Harapan, a prospective clinical trial conducted among people living with HIV and opioid dependence who transitioned from prison to the community in Malaysia from 2010 to 2014. This trial involved 2 interventions: within-prison initiation of methadone maintenance therapy and an evidence-based behavioral intervention adapted to the Malaysian context (the Holistic Health Recovery Program for Malaysia, HHRP-M). Individuals were recruited and received the interventions while incarcerated and were followed for 12months after release to assess post-release HIV transmission risk behaviors and a range of other health-related outcomes. Project Harapan was designed as a fully randomized 2×2 factorial trial where individuals would be allocated in equal proportions to methadone maintenance therapy and HHRP-M, methadone maintenance therapy alone, HHRP-M alone, or control. Partway through study implementation, allocation to methadone maintenance therapy was changed from randomization to participant choice; randomization to HHRP-M continued throughout. We describe the justification for this study; the development and implementation of these interventions; changes to the protocol; and screening, enrollment, treatment receipt, and retention of study participants. Logistical, ethical, and analytic issues associated with the implementation of this study are discussed. Copyright © 2017 Elsevier Inc. All rights reserved.

The association of aggressive periodontitis with Kindler syndrome was based on a single case in 1996 and later confirmed with a larger population. Since then, significant research has greatly increased our understanding of the molecular pathology of this disorder. We review recent advances in the molecular mechanisms of the syndrome and present a maintenance case report of a patient who has been followed in our clinic. A female patient who was diagnosed with Kindler syndrome and aggressive periodontitis at the age of 16 years has been followed and treated in our clinic for 12 years. Her main treatment has been maintenance therapy following her initial treatment and restorative work previously documented. Gingival biopsies obtained during the recent extraction of hopeless maxillary molars were used for histologic assessment of gingival tissue attachment apparatus and to isolate gingival fibroblasts. Reverse transcription-polymerase chain reaction (RT-PCR) was performed using these cells to confirm the lack of expression of kindlin-1. RT-PCR showed the total loss of kindlin-1 mRNA in cultured gingival fibroblasts, supporting the clinical diagnosis of Kindler syndrome. Tissue biopsies revealed atypical pocket epithelium. Maintenance therapy has been moderately successful. Teeth that were recently lost had a poor prognosis at the initial assessment. The patient's gingiva and oral mucosa continue to be fragile with episodes of sloughing and inflammation. Periodontitis in Kindler syndrome responds to maintenance therapy, but the gingiva and oral mucosa continue to display an abnormal appearance with white patches. Histologic findings suggest that the junctional epithelium in Kindler syndrome may be abnormal and could explain why these patients have periodontal disease. Attachment loss progressed around teeth with an initial guarded or poor prognosis. Teeth that started with a good or fair prognosis continue to have a fair prognosis. Limited dental implant treatment is being considered.

The Key Points of Maintenance Therapy for Dental Implants: A Literature Review.

PubMed

Pirc, Miha; Dragan, Irina F

2017-04-01

Dental implants require lifelong maintenance and care. Success is defined by biologic factors (presence of inflamed soft tissues surrounding dental implants and radiographic changes in the crestal bone levels) and mechanical factors (stability of the implant fixture and implant supported restoration, etc). Most implant failures are initiated by incipient stages of inflammatory processes, which lead to peri-mucositis and peri-implantitis. The evidence regarding the value of maintenance protocol regarding implants is sparse compared with the one for teeth. This article addresses the existing literature on processes for oral hygiene for implant care.

Single photodynamic therapy (PDT) has been effective in initial periodontal therapy, but only improved bleeding on probing (BoP) in maintenance patients after a single use. Repeated PDT has not been addressed. To study the possible added benefits of repeated adjunctive PDT to conventional treatment of residual pockets in patients enrolled in periodontal maintenance. Ten maintenance patients with 70 residual pockets [probing pocket depth (PPD)>or=5 mm] were randomly assigned for treatment five times in 2 weeks (Days 0, 1, 2, 7, 14) with PDT (test) or non-activated laser (control) following debridement. The primary outcome variable was PPD, and the secondary variables were clinical attachment level (CAL) and BoP. These were assessed at 3, 6 and 12 months following the interventions. Greater PPD reductions were observed in the test (-0.67 +/- 0.34; p=0.01) compared with the control patients (-0.04 +/- 0.33; NS) after 6 months. Significant CAL gain (+0.52 +/- 0.31; p=0.01) was noted for the test, but not in the control (-0.27 +/- 0.52; NS) patients after 6 months. BoP percentages decreased significantly in test (97-64%, 67%, 77%), but not control patients after 3, 6 and 12 months. Repeated (five times) PDT adjunctive to debridement yielded improved clinical outcomes in residual pockets in maintenance patients. The effects were best documented after 6 months.

We compared the effect on weight regain of behaviour modification consisting of either a gourmet cooking course or neurolinguistic programming (NLP) therapy. Fifty-six overweight and obese subjects participated. The first step was a 12-week weight loss program. Participants achieving at least 8% weight loss were randomized to five months of either NLP therapy or a course in gourmet cooking. Follow-up occurred after two and three years. Forty-nine participants lost at least 8% of their initial body weight and were randomized to the next step. The NLP group lost an additional 1.8 kg and the cooking group lost 0.2 kg during the five months of weight maintenance (NS). The dropout rate in the cooking group was 4%, compared with 26% in the NLP group (p=0.04). There was no difference in weight maintenance after two and three years of follow-up. In conclusion, weight loss in overweight and obese participants was maintained equally efficiently with a healthy cooking course or NLP therapy, but the dropout rate was lower during the active cooking treatment.

Purpose: To present the first report of a Phase I trial evaluating concurrent and maintenance erlotinib and reirradiation in patients with recurrent or secondary primary head-and-neck cancer (HNC). Methods and Materials: Patients with recurrent or new primary HNC with an interval of at least 6 months since prior radiation were eligible. Patients were treated in 3 sequential cohorts: Cohort I, 100 mg of erlotinib daily with reirradiation at 61.6 Gy in 28 fractions; Cohort II, 150 mg of erlotinib with 61.6 Gy in 28 fractions; and Cohort III, 150 mg of erlotinib with 66 Gy in 30 fractions. Maintenance erlotinibmore » started immediately after reirradiation at 150 mg daily and was continued for 2 years or until disease progression or dose-limiting toxicity. Dose-limiting toxicities were defined as any Grade 4 or 5 toxicity or a toxicity-related delay in radiation therapy of greater than 7 days. Results: Fourteen patients were accrued, 3 to Cohort I, 4 to Cohort II, and 7 to Cohort III. Thirteen patients were evaluable for toxicity. Median follow-up was 8.4 months overall and 15.1 months for surviving patients. One patient had a dose-limiting toxicity in Cohort III. This patient declined initial percutaneous endoscopic gastrostomy tube placement, was hospitalized with Grade 3 dysphagia and aspiration, and required a delay in radiation therapy of greater than 7 days. No Grade 4 acute toxicity was observed. Acute Grade 3 toxicity occurred in 9 of 13 patients. No erlotinib-related toxicity of Grade 3 or greater was observed during maintenance therapy. One patient had Grade 5 carotid hemorrhage 6 months after reirradiation, and another patient had Grade 3 osteoradionecrosis. Conclusions: Reirradiation (66 Gy in 2.2 Gy fractions) with concurrent and maintenance erlotinib (150 mg daily) for recurrent or new primary HNC is feasible.« less

Maintenance therapy for patients with advanced non-small-cell lung cancer (NSCLC) is an increasingly hot topic in the field of clinical NSCLC research. This study aimed to evaluate the effects of Traditional Chinese Medicine (TCM) treatment as maintenance therapy on time to progression (TTP), quality of life (QOL), overall survival (OS) and 1-year survival rate in patients with advanced NSCLC. This study was conducted as a randomized, controlled, open-label trial. 64 non-progressive patients who responded to initial therapy were randomized 1:1 to the TCM arm (treated with herbal injection (Cinobufacini, 20ml/d, d1-d10), herbal decoction (d1-d21) and Chinese acupoint application (d1-d21), n=32) or to the chemotherapy arm (treated with pemetrexed (non-squamous NSCLC, 500mg/m(2), d1), docetaxel (75mg/m(2), d1) or gemcitabine (1250mg/m(2), d1 and d8), n=32). Each therapy cycle was 21 days. They were repeated until disease progression, unacceptable toxicity, or until the patients requested therapy discontinuation. The primary end point was TTP; the secondary end points were QOL, OS and 1-year survival rate. "Intention-to-treat" analysis included all randomized participants. TCM treatment prolonged median TTP for 0.7 months compared with chemotherapy, but it was not statistically significant (3.0 months vs. 2.3 months, P=0.114). Median OS time for TCM treatment did not offer a significant advantage over for chemotherapy (21.5 months vs. 18.8 months, P=0.601). 1-year survival rate of TCM treatment significantly improved than that of chemotherapy (78.1% vs. 53.1%, P=0.035). TCM treatment can significantly improve QOL when compared to chemotherapy as assessed by EORTC QLQ-C30 and EORTC QLQ-LC13 QOL instruments. TCM maintenance treatment had similar effects on TTP and OS compared with maintenance chemotherapy, but it improved patients' QOL and had higher 1-year survival rate. TCM Maintenance treatment is a promising option for advanced NSCLC patients without progression following first-line chemotherapy. Copyright © 2015 Elsevier Ltd. All rights reserved.

Objectives Maintenance therapy is a standard therapeutic strategy in non-squamous non-small-cell lung cancer. However, there is no consensus regarding the benefit of maintenance therapy for patients with squamous cell lung cancer. We assessed maintenance therapy with S-1, an oral fluoropyrimidine agent, following induction therapy with carboplatin and S-1 in patients with squamous cell lung cancer. Methods In this phase II trial, chemotherapy-naïve patients with squamous cell lung cancer were enrolled to induction therapy with four cycles of carboplatin (at an area under the curve of 5 on day 1) and S-1 (80 mg/m(2)/day on days 1-14) in a 28-day cycle. Patients who achieved disease control after induction therapy received maintenance therapy with S-1 in a 21-day cycle until disease progression or unacceptable toxicity. The primary endpoint was progression-free survival after administration of maintenance therapy. Results Fifty-one patients were enrolled in the study. The median progression-free survival from the start of maintenance therapy was 3.0 months (95 % confidence interval, 2.5-3.5). The most common toxicities associated with maintenance therapy were anemia, thrombocytopenia, and fatigue, but they were not severe. Conclusion S-1 maintenance therapy might be a feasible treatment option in patients with squamous cell lung cancer.

Navigated laser therapy introduces for the first time computerized assistance systems for retinal laser therapy. The Navilas system offers high precision and safety and provides additional benefits regarding standardization of planning, execution, documentation and quality assurance. The current focus of clinical application for navigated laser therapy besides laser treatment after retinal vein occlusion and panretinal laser photocoagulation in proliferative diabetic retinopathy (PDR) is diabetic macular edema. Recent data indicate that combined initial anti-vascular endothelial growth factor (anti-VEGF) and navigated macular laser therapy allows achievement and maintenance of treatment success with a minimum number of interventions. Despite very promising results the current assessment of navigated laser therapy is still limited by the evidence available worldwide.

Challenges in economic modeling of anticancer therapies: an example of modeling the survival benefit of olaparib maintenance therapy for patients with BRCA-mutated platinum-sensitive relapsed ovarian cancer.

Hettle, Robert; Posnett, John; Borrill, John

2015-01-01

The aim of this paper is to describe a four health-state, semi-Markov model structure with health states defined by initiation of subsequent treatment, designed to make best possible use of the data available from a phase 2 clinical trial. The approach is illustrated using data from a sub-group of patients enrolled in a phase 2 clinical trial of olaparib maintenance therapy in patients with platinum-sensitive relapsed ovarian cancer and a BRCA mutation (NCT00753545). A semi-Markov model was developed with four health states: progression-free survival (PFS), first subsequent treatment (FST), second subsequent treatment (SST), and death. Transition probabilities were estimated by fitting survival curves to trial data for time from randomization to FST, time from FST to SST, and time from SST to death. Survival projections generated by the model are broadly consistent with the outcomes observed in the clinical trial. However, limitations of the trial data (small sample size, immaturity of the PFS and overall survival [OS] end-points, and treatment switching) create uncertainty in estimates of survival. The model framework offers a promising approach to evaluating cost-effectiveness of a maintenance therapy for patients with cancer, which may be generalizable to other chronic diseases.

Recurrent vulvovaginal candidiasis (RVVC) is a common condition that can physically and psychologically impact patients. We compared the efficacy and safety of vaginal nystatin suppositories for 14 days each month versus standard oral fluconazole regimens for the treatment for RVVC. Patients (n = 293) were enrolled in the study from April 2010 to September 2013. After the initial therapy, the mycological cure rates were 78.3% (119/152) and 73.8% (104/141) in the nystatin group and fluconazole group, respectively (95% CI, 0.749-2.197, p > 0.05). The mycological cure rates at the end of maintenance therapy were 80.7% (96/119) and 72.7% (72/99) in the two groups, respectively (95% CI, 0.954-3.293, p > 0.05).The mycological cure rates at the end without treatment for 6 months were 81.25% (78/96) and 82.19% (60/73) in the two groups, respectively (95% CI, 0.427-2.066, p > 0.05). The mycological cure rates of RVVC caused by C. albicans were 84.0% (89/106) and 81.8% (99/121) in the two groups, respectively. The mycological cure rates of RVVC caused by C. glabrata were 64.3% (27/42) and 12.5% (2/16) in the two groups, respectively. The initial and 6-month maintenance therapy were successful in five of the nine patients in the nystatin group with RVVC caused by fluconazole-resistant Candida, whereas in the fluconazole group, initial therapy failed in all patients with RVVC caused by fluconazole-resistant Candida (n = 7). We conclude that both fluconazole and nystatin therapies are effective in treating RVVC. Nystatin may also be effective for the treatment for RVVC caused by C. glabrata or fluconazole-resistant Candida.

Purpose The objective of this study was to investigate clinical and laboratory parameters that could predict which patients could maintain adequate glycemic control after switching from initial insulin therapy to oral hypoglycemic agents (OHAs) among patients with type 2 diabetes (T2D). Materials and Methods We recruited 275 patients with T2D who had been registered in 3 cohorts of initiated insulin therapy and followed up for 33 months. The participants were divided into 2 groups according to whether they switched from insulin to OHAs (Group I) or not (Group II), and Group I was further classified into 2 sub-groups: maintenance on OHAs (Group IA) or resumption of insulin (Group IB). Results Of 275 patients with insulin initiation, 63% switched to OHAs (Group I) and 37% continued insulin (Group II). Of these, 44% were in Group IA and 19% in Group IB. The lowest tertile of baseline postprandial C-peptide-to-glucose ratio (PCGR), higher insulin dose at switching to OHAs, and higher HbA1c level at 6 months after switching to OHAs were all associated with OHA failure (Group IB; p=0.001, 0.046, and 0.014, respectively). The lowest tertile of PCGR was associated with ultimate use of insulin (Group IB and Group II; p=0.029). Conclusion Higher baseline level of PCGR and lower HbA1c levels at 6 months after switching to OHAs may be strong predictors for the successful maintenance of OHAs after switching from insulin therapy in Korean patients with T2D.

The introduction of all-trans-retinoic acid (ATRA) has significantly improved outcomes for acute promyelocytic leukemia (APL), although a subset of patients still suffer relapse. The purpose of this study was to evaluate the role of maintenance therapy with the synthetic retinoid tamibarotene in APL. Patients with newly diagnosed APL in molecular remission at the end of consolidation therapy were randomly assigned to receive ATRA or tamibarotene, both orally, for 14 days every 3 months for up to 2 years. A total of 347 patients were enrolled. Of the 344 eligible patients, 319 (93%) achieved complete remission. After completing three courses of consolidation therapy, 269 patients underwent maintenance random assignment. The relapse-free survival (RFS) rate at 4 years was 84% for the ATRA arm and 91% for the tamibarotene arm (hazard ratio [HR], 0.54; 95% CI, 0.26 to 1.13). When the analysis was restricted to 52 high-risk patients with an initial WBC count ≥ 10.0 × 10(9)/L, the intergroup difference was statistically significant, with 4-year RFS rates of 58% for the ATRA arm and 87% for the tamibarotene arm (HR, 0.26; 95% CI, 0.07 to 0.95). For patients with non-high-risk disease, the HR was 0.82 (95% CI, 0.32 to 2.01). The test for interaction between treatment effects and these subgroups resulted in P = .075. Both treatments were generally well tolerated. In this trial, no difference was detected between ATRA and tamibarotene for maintenance therapy. In an exploratory analysis, there was a suggestion of improved efficacy of tamibarotene in high-risk patients, but this requires further study. © 2014 by American Society of Clinical Oncology.

To report what we believe to be the first 2 cases of long-term (>24 months) intermittent intravenous interleukin-2 receptor antibody (IL-2RA) therapy for maintenance immunosuppression following renal transplantation. The first patient is a 52-year-old female with a history of intolerance to calcineurin inhibitors (CNIs) and sirolimus. Following her second transplant, the patient received mycophenolate mofetil 100 mg twice daily, a tapering corticosteroid regimen (initial dose of methylprednisolone 500 mg tapered over 1 week to prednisone 30 mg/day), and biweekly intravenous daclizumab 1-1.2 mg/kg/dose; 33 months after transplant the IL-2RA was changed to intravenous basiliximab 40 mg once a month. At 40 months after transplant, the patient continued to have stable renal function (estimated glomerular filtration rate 48 mL/min/1.73 m²) with excellent tolerability. The second patient is a 59-year-old female also intolerant to CNIs and sirolimus who required intermittent maintenance therapy with intravenous basiliximab 20 mg/dose. Despite an initial rejection episode, the patient tolerated more than 2 years of basiliximab therapy with good renal function (estimated glomerular filtration rate 103 months after transplant 69 mL/min/1.73 m²) and no adverse events. The IL-2RAs basiliximab and daclizumab possess several characteristics of ideal maintenance immunosuppressive agents (ie, nondepleting, long half-lives, limited adverse events). Based on a MEDLINE search (through December 31, 2010) using the search terms basiliximab, daclizumab, organ transplant, immunosuppression, and/or maintenance immunosuppression, and an advanced search in the published abstracts from the American Transplant Congress and World Transplant Congress (2000-2010), it appears that IL-2RAs have been used successfully as short-term therapy in both renal and extrarenal transplant recipients to allow for renal recovery following CNI-induced nephrotoxicity. In heart transplant recipients, the IL-2RAs have been used for <24 months as maintenance immunosuppression in patients intolerant of CNIs or sirolimus. To the best of our knowledge, these 2 cases are the first to demonstrate that IL-2RAs can be used as an alternative to a CNI in a de novo immunosuppressive regimen. Also, this is the first report to illustrate successful long-term use of IL-2RAs in renal transplant recipients. This alternative approach was well tolerated by our patients, with no apparent adverse events. Although the efficacy of such regimens cannot be determined with 2 case reports, the fact that intermittent intravenous IL-2RA administration was successfully accomplished in these patients provides impetus to evaluate this treatment modality in prospective studies.

Fluid therapy for children: facts, fashions and questions

Fluid therapy restores circulation by expanding extracellular fluid. However, a dispute has arisen regarding the nature of intravenous therapy for acutely ill children following the development of acute hyponatraemia from overuse of hypotonic saline. The foundation on which correct maintenance fluid therapy is built is examined and the difference between maintenance fluid therapy and restoration or replenishment fluid therapy for reduction in extracellular fluid volume is delineated. Changing practices and the basic physiology of extracellular fluid are discussed. Some propose changing the definition of “maintenance therapy” and recommend isotonic saline be used as maintenance and restoration therapy in undefined amounts leading to excess intravenous sodium chloride intake. Intravenous fluid therapy for children with volume depletion should first restore extracellular volume with measured infusions of isotonic saline followed by defined, appropriate maintenance therapy to replace physiological losses according to principles established 50 years ago.

Cyanotic congenital heart disease (CCHD) is a life-threatening cardiac defect that requires palliative or corrective surgery in early life. Major advances in medical and surgical management have resulted in the survival of CCHD patients to adulthood with or without corrective surgery, though some are at risk of development of end-stage renal disease (ESRD) due to cyanotic nephropathy (CN). There is little or no information on the initiation and maintenance of hemodialysis (HD) in such patients. We present here a case of a 44-year-old man with complete transposition of the great arteries and CN-related ESRD. He had only received a bi-directional Glenn's operation and still suffered persistent severe hypoxemia and impaired cardiac function. ESRD was successfully treated with HD over more than 4 years. The case emphasizes the need for special attention in the selection and initiation of renal replacement therapy.

Non-fluent speech following stroke is caused by impaired efference copy.

Efference copy is a cognitive mechanism argued to be critical for initiating and monitoring speech: however, the extent to which breakdown of efference copy mechanisms impact speech production is unclear. This study examined the best mechanistic predictors of non-fluent speech among 88 stroke survivors. Objective speech fluency measures were subjected to a principal component analysis (PCA). The primary PCA factor was then entered into a multiple stepwise linear regression analysis as the dependent variable, with a set of independent mechanistic variables. Participants' ability to mimic audio-visual speech ("speech entrainment response") was the best independent predictor of non-fluent speech. We suggest that this "speech entrainment" factor reflects integrity of internal monitoring (i.e., efference copy) of speech production, which affects speech initiation and maintenance. Results support models of normal speech production and suggest that therapy focused on speech initiation and maintenance may improve speech fluency for individuals with chronic non-fluent aphasia post stroke.

Treating opioid dependence. Growing implications for primary care.

Krantz, Mori J; Mehler, Philip S

2004-02-09

Almost 3 million Americans have abused heroin. The most effective treatment for this concerning epidemic is opioid replacement therapy. Although, from a historical perspective, acceptance of this therapy has been slow, growing evidence supports its efficacy. There are 3 approved medications for opioid maintenance therapy: methadone hydrochloride, levomethadyl acetate, and buprenorphine hydrochloride. Each has unique characteristics that determine its suitability for an individual patient. Cardiac arrhythmias have been reported with methadone and levomethadyl, but not with buprenorphine. Due to concerns about cardiac risk, levomethadyl use has declined and the product may ultimately be discontinued. These recent safety concerns, specifics about opioid detoxification and maintenance, and new federal initiatives were studied. Opioid detoxification has a role in both preventing acute withdrawal and maintaining long-term abstinence. Although only a minority of eligible patients are engaged in treatment, opioid maintenance therapy appears to offer the greatest public health benefits. There is growing interest in expanding treatment into primary care, allowing opioid addiction to be managed like other chronic illnesses. This model has gained wide acceptance in Europe and is now being implemented in the United States. The recent Drug Addiction Treatment Act enables qualified physicians to treat opioid-dependent patients with buprenorphine in an office-based setting. Mainstreaming opioid addiction treatment has many advantages; its success will depend on resolution of ethical and delivery system issues as well as improved and expanded training of physicians in addiction medicine.

Addiction treatment-related Employment barriers: the impact of methadone maintenance

Richardson, Lindsey; Wood, Evan; Montaner, Julio; Kerr, Thomas

2012-01-01

Employment is commonly upheld as an important outcome of addiction treatment. To explore this attribution we assessed whether treatment enrolment predicts employment initiation among participants enrolled in a community-recruited Canadian cohort of people who inject drugs (IDU) (n=1579). Survival analysis initially found no association between addiction treatment enrolment and employment initiation. However, when methadone maintenance therapy (MMT) was separated from other treatment modalities, non-MMT treatment positively predicted employment transitions, while MMT was negatively associated with employment initiation. Sub-analyses examining transitions into temporary, informal and under-the-table income generation echo these results. Findings suggest that individual factors impacting employment transitions may systematically apply to MMT clients, and that, in this setting, the impact of treatment on employment outcomes is contingent on treatment type and design. Treatment-specific differences underscore the need to expand low-threshold MMT, explore MMT alternatives and evaluate the impact of treatment design on the social and economic activity of IDU.

Cancer stem-like cells (CSCs)/ cancer-initiating cells (CICs) are defined by their higher tumor-initiating ability, self-renewal capacity and differentiation capacity. CSCs/CICs are resistant to several therapies including chemotherapy and radiotherapy. CSCs/CICs thus are thought to be responsible for recurrence and distant metastasis, and elucidation of the molecular mechanisms of CSCs/CICs are essential to design CSC/CIC-targeting therapy. In this study, we analyzed the molecular aspects of gynecological CSCs/CICs. Gynecological CSCs/CICs were isolated as ALDH1high cell by Aldefluor assay. The gene expression profile of CSCs/CICs revealed that several genes related to stress responses are preferentially expressed in gynecological CSCs/CICs. Among the stress response genes, a small heat shock protein HSP27 has a role in the maintenance of gynecological CSCs/CICs. The upstream transcription factor of HSP27, heat shock factior-1 (HSF1) was activated by phosphorylation at serine 326 residue (pSer326) in CSCs/CICs, and phosphorylation at serine 326 residue is essential for induction of HSP27. Immunohistochemical staining using clinical ovarian cancer samples revealed that higher expressions of HSF1 pSer326 was related to poorer prognosis. These findings indicate that activation of HSF1 at Ser326 residue and transcription of HSP27 is related to the maintenance of gynecological CSCs/CICs. PMID:28415561

It is difficult to treat patients who, in addition to having severe anorexia nervosa, also have severe symptoms of major depressive disorder and a tendency for impulsive acting out behaviour. Our case report considers the feasibility of maintenance electroconvulsive therapy in such complicated cases. This is a case report of a woman with anorexia nervosa and co-morbid severe major depressive disorder who was treated with electroconvulsive therapy as a maintenance treatment. The maintenance electroconvulsive therapy was conducted without immediate complications. It had a positive effect on the patient's depressive symptoms and lability and her general wellbeing, although some cognitive deficits were observed. The maintenance electroconvulsive therapy seemed to support recovery in a case of refractory anorexia nervosa and a tendency for labile mood. The symptoms of co-occurring major depressive disorder were partly relieved and maintenance electroconvulsive therapy had some positive effect on weight gain.

IL-2 is a natural, T cell-derived cytokine that stimulates the cytotoxic functions of T and natural killer cells. IL-2 monotherapy has been evaluated in several randomized clinical trials (RCTs) for remission maintenance in patients with acute myeloid leukemia (AML) in first complete remission (CR1), and none demonstrated a significant benefit of IL-2 monotherapy. The objective of this meta-analysis was to reliably determine IL-2 efficacy by combining all available individual patient data (IPD) from 5 RCTs (N = 905) and summary data from a sixth RCT (N = 550). Hazard ratios (HRs) were estimated using Cox regression models stratified by trial, with HR < 1 indicating treatment benefit. Combined IPD showed no benefit of IL-2 over no treatment in terms of leukemia-free survival (HR = 0.97; P = .74) or overall survival (HR = 1.08; P = .39). Analyses including the sixth RCT yielded qualitatively identical results (leukemia-free survival HR = 0.96, P = .52; overall survival HR = 1.06; P = .46). No significant heterogeneity was found between the trials. Prespecified subset analyses showed no interaction between the lack of IL-2 effect and any factor, including age, sex, baseline performance status, karyotype, AML subtype, and time from achievement of CR1 to initiation of maintenance therapy. We conclude that IL-2 alone is not an effective remission maintenance therapy for AML patients in CR1.

Switch maintenance therapy, using alternative agents that were not administered during induction chemotherapy, is a treatment option for advanced non-squamous non-small cell lung cancer (NSCLC). Bevacizumab is known to increase the efficacy of other chemotherapeutic agents; however, switch maintenance therapy with docetaxel and bevacizumab has not been adequately studied. The goal of this study was to evaluate the efficacy and safety of switch maintenance therapy with docetaxel and bevacizumab following induction therapy with cisplatin, pemetrexed, and bevacizumab. Chemotherapy-naïve non-squamous NSCLC patients received induction therapy of four cycles of cisplatin (75 mg/m 2 ), pemetrexed (500 mg/m 2 ), and bevacizumab (15 mg/kg). Patients who achieved disease control after induction therapy then received maintenance therapy with docetaxel (50 mg/m 2 ) and bevacizumab (15 mg/kg) until disease progression or unacceptable toxicity. The primary endpoint was progression-free survival from enrollment. This study enrolled 49 NSCLC patients, among which 38 (77.6%) completed the four cycles of induction therapy and received maintenance therapy. The median progression-free survival from enrollment was 7.8 months (95% confidence interval: 4.7-11.0 months). The most common toxicities of grade 3 or higher were neutropenia (68.4%), leukopenia (50.0%), febrile neutropenia (31.8%), and hypertension. Switch maintenance therapy with docetaxel and bevacizumab following induction therapy with cisplatin, pemetrexed, and bevacizumab demonstrated modest efficacy and frequent hematologic toxicity in non-squamous NSCLC patients.

Acute course of electroconvulsive therapy is effective in inducing remission from depression, but recurrence rate is unacceptably high following termination of electroconvulsive therapy despite continued pharmacotherapy. Continuation electroconvulsive therapy and maintenance electroconvulsive therapy have been studied for their efficacy in preventing relapse and recurrence of depression. The purpose of this meta-analysis was to examine the efficacy of continuation electroconvulsive therapy and maintenance electroconvulsive therapy in preventing relapse and recurrence of depression in comparison to antidepressant pharmacotherapy alone. We searched MEDLINE, Embase, PsycINFO, clinicaltrials.gov and Cochrane register of controlled trials from the database inception to December 2016 without restriction on language or publication status for randomized trials of continuation electroconvulsive therapy and maintenance electroconvulsive therapy. Two independent Cochrane reviewers extracted the data in accordance with Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines for systematic reviews and meta-analyses. The risk of bias was assessed using four domains of the Cochrane Collaboration Risk of Bias Tool. Outcomes were pooled using random effect model. The primary outcome was relapse or recurrence of depression. Five studies involving 436 patients were included in the meta-analysis. Analysis of the pooled data showed that continuation electroconvulsive therapy and maintenance electroconvulsive therapy, both with pharmacotherapy, were associated with significantly fewer relapses and recurrences than pharmacotherapy alone at 6 months and 1 year after a successful acute course of electroconvulsive therapy (risk ratio = 0.64, 95% confidence interval = [0.41, 0.98], p = 0.04, risk ratio = 0.46, 95% confidence interval = [0.21, 0.98], p = 0.05, respectively). There was insufficient data to perform a meta-analysis of stand-alone continuation electroconvulsive therapy or maintenance electroconvulsive therapy beyond 1 year. There are only a few randomized trials of continuation electroconvulsive therapy and maintenance electroconvulsive therapy. The preliminary and limited evidence suggests the modest efficacy of continuation electroconvulsive therapy and maintenance electroconvulsive therapy with concomitant pharmacotherapy in preventing relapse and recurrence of depressive episodes for 1 year after the remission of index episode with the acute course of electroconvulsive therapy.

It is not clear whether the pattern of kidney function decline in patients with chronic kidney disease (CKD) may relate to outcomes after reaching end-stage renal disease (ESRD). We hypothesize that an abrupt decline in kidney function prior to ESRD predicts early death after initiating maintenance hemodialysis therapy. Prospective cohort study. The Chronic Renal Insufficiency Cohort (CRIC) Study enrolled men and women with mild to moderate CKD. For this study, we studied 661 individuals who developed chronic kidney failure that required hemodialysis therapy initiation. The primary predictor was the presence of an abrupt decline in kidney function prior to ESRD. We incorporated annual estimated glomerular filtration rates (eGFRs) into a mixed-effects model to estimate patient-specific eGFRs at 3 months prior to initiation of hemodialysis therapy. Abrupt decline was defined as having an extrapolated eGFR≥30mL/min/1.73m(2) at that time point. All-cause mortality within 1 year after initiating hemodialysis therapy. Multivariable Cox proportional hazards. Among 661 patients with CKD initiating hemodialysis therapy, 56 (8.5%) had an abrupt predialysis decline in kidney function and 69 died within 1 year after initiating hemodialysis therapy. After adjustment for demographics, cardiovascular disease, diabetes, and cancer, abrupt decline in kidney function was associated with a 3-fold higher risk for death within the first year of ESRD (adjusted HR, 3.09; 95% CI, 1.65-5.76). Relatively small number of outcomes; infrequent (yearly) eGFR determinations; lack of more granular clinical data. Abrupt decline in kidney function prior to ESRD occurred in a significant minority of incident hemodialysis patients and predicted early death in ESRD.

This case report describes the successful treatment of a severe chronic periodontitis case by nonsurgical therapy and a strict maintenance program over a 12-year period. A 38-year-old man concerned about the protrusion of his maxillary incisors was referred for periodontal treatment. The teeth in the maxillary arch had generalized severe chronic periodontitis. Several treatment options were presented to the patient including the most aggressive, extraction of all maxillary teeth, and the most conservative, scaling and root planing. The patient opted to having the most conservative approach, even though the prognoses for the maxillary teeth were unfavorable. Therefore, he received nonsurgical therapy via scaling and root planing combined with systemic antibiotics before referral to an orthodontist to address the esthetic concerns. The maxillary dentition was treated with orthodontic therapy to retract and align the maxillary anterior segment. Periodontal maintenance (1-hour session), including subgingival instrumentation, was performed 4 times per year until the end of the 12-year follow-up period. The patient only missed 2 appointments in 12 years. Twelve years later, the results revealed that all but 1 maxillary tooth were maintained in a state of acceptable health, function, and esthetics. Although most would agree with the initial poor prognosis of this patient's case, nonsurgical periodontal therapy was utilized with a 3-month periodontal maintenance program and demonstrated long-term success. The outcome presented in this case report may only have been possible because of patient compliance, professional experience, skill, and supervision throughout the course of treatment.

Lasers and light sources for rosacea.

Goldberg, David J

2005-03-01

Pharmacologic agents remain the mainstay for initial and maintenance treatment of rosacea. However, monochromatic (i.e., laser) and polychromatic light-based therapies are increasingly being used for the treatment of certain signs of rosacea. Despite the increased use of lasers and other light-based therapies, few well-controlled studies have been conducted on their use for the treatment of rosacea. The studies that do exist suggest that these modalities have value in treating erythematotelangiectatic rosacea, including persistent erythema and phymatous rosacea. Light-based therapies should be strongly considered in cases of serious erythema, flushing, and telangiectasia because these signs are not optimally addressed by pharmacologic interventions.

Diagnosis and management of dehydration in children.

2009-10-01

The most useful individual signs for identifying dehydration in children are prolonged capillary refill time, abnormal skin turgor, and abnormal respiratory pattern. However, clinical dehydration scales based on a combination of physical examination findings are better predictors than individual signs. Oral rehydration therapy is the preferred treatment of mild to moderate dehydration caused by diarrhea in children. Appropriate oral rehydration therapy is as effective as intravenous fluid in managing fluid and electrolyte losses and has many advantages. Goals of oral rehydration therapy are restoration of circulating blood volume, restoration of interstitial fluid volume, and maintenance of rehydration. When rehydration is achieved, a normal age-appropriate diet should be initiated.

The end-stage renal disease Medical Evidence Report serves as a source of comorbid condition data for risk adjustment of quality metrics. We sought to compare comorbid condition data in the Medical Evidence Report around dialysis therapy initiation with diagnosis codes in Medicare claims. Observational cohort study using US Renal Data System data. Medicare-enrolled elderly (≥66 years) patients who initiated maintenance dialysis therapy July 1 to December 31, 2007, 2008, or 2009. 12 comorbid conditions ascertained from claims during the 6 months before dialysis therapy initiation, the Medical Evidence Report, and claims during the 3 months after dialysis therapy initiation. None. Comorbid condition prevalence according to claims before dialysis therapy initiation generally exceeded prevalence according to the Medical Evidence Report. The κ statistics for comorbid condition designations other than diabetes ranged from 0.06 to 0.43. Discordance of designations was associated with age, race, sex, and end-stage renal disease Network. During 23,930 patient-years of follow-up from 4 to 12 months after dialysis therapy initiation (8,930 deaths), designations from claims during the 3 months after initiation better discriminated risk of death than designations from the Medical Evidence Report (C statistics of 0.674 vs 0.616). Between the Medical Evidence Report and claims, standardized mortality ratios changed by >10% for more than half the dialysis facilities. Neither the Medical Evidence Report nor diagnosis codes in claims constitute a gold standard of comorbid condition data; results may not apply to nonelderly patients or patients without Medicare coverage. Discordance of comorbid condition designations from the Medical Evidence Report and claims around dialysis therapy initiation was substantial and significantly associated with patient characteristics, including location. These patterns may engender bias in risk-adjusted quality metrics. In lieu of the Medical Evidence Report, claims during the 3 months after dialysis therapy initiation may constitute a useful source of comorbid condition data.

To compare various conservative treatment options for high-grade T1 nonmuscle-invasive bladder cancer (NMIBC). Bacille Calmette-Guérin (BCG) is the preferred intravesical treatment for high-grade T1 tumours; however, a number of experts still question the need for maintenance BCG. We retrospectively analysed data from 1039 patients with primary and recurrent T1G3 NMIBC. All patients underwent complete transurethral resection of the bladder tumour (TURBT), with muscle in the sample and multiple bladder biopsies. The patients were treated with the following: only one initial TURBT (n=108), re-TURBT (n=153), induction with 27mg of BCG (Connaught strain) (n=87), induction with 81mg of BCG (n=489) or induction with 81mg of BCG+maintenance (n=202). The time to first recurrence, progression (to T2 or greater or to metastatic disease) and specific mortality of the disease was assessed using the Kaplan-Meier survival function and were compared using the log-rank test and the Cox multivariate regression model of proportional risks. The mean follow-up was 62±39 months. The risk of recurrence was significantly lower for the patients treated with maintenance therapy of 81mg of BCG than in the other treatment groups (P<.001). The risk of tumour progression was also significantly lower for the patients treated with maintenance BCG than for the patients treated only with one TURBT, re-TURBT and with induction therapy with 27mg of BCG (P=.0003). The specific disease mortality was significantly lower with BCG maintenance (9.4%) than with only one TURBT (27.8%; P=.003). In the case of T1G3 NMIBC, a complete dose of BCG with maintenance is associated with better recurrence results than are other conservative treatment modalities. The results of progression and survival specific to the disease were also better with induction BCG, with or without maintenance. Copyright © 2016 AEU. Publicado por Elsevier España, S.L.U.

Fluid management during continuous renal replacement therapy (CRRT) in critically ill patients is a dynamic process that encompasses 3 inter-related goals: maintenance of the patency of the CRRT circuit, maintenance of plasma electrolyte and acid-base homeostasis and regulation of patient fluid balance. In this article, we report the consensus recommendations of the 2016 Acute Disease Quality Initiative XVII conference on 'Precision Fluid Management in CRRT'. We discuss the principles of fluid management, describe various prescription methods to achieve circuit integrity and introduce the concept of integrated fluid balance for tailoring fluid balance to the needs of the individual patient. We suggest that these recommendations could serve to develop the best clinical practice and standards of care for fluid management in patients undergoing CRRT. Finally, we identify and highlight areas of uncertainty in fluid management and set an agenda for future research. © 2016 S. Karger AG, Basel.

Maintenance therapy proves to be effective in advanced lung and breast cancer after initial chemotherapy. The purpose of this phase II study was to evaluate the efficacy and safety of Uracil and Tegafur (UFT) maintenance in metastatic gastric cancer patients following the first-line fluorouracil-based chemotherapy. Metastatic gastric cancer patients with stable disease or a better response after the completion of first-line chemotherapy were randomized to oral UFT (360mg/m2 × 2 weeks) every 3 weeks until disease progression/intolerable toxicity or to observation (OBS). The primary endpoint was progression-free survival (PFS); the secondary endpoints were overall survival (OS) and safety. The trial was closed after the interim analysis of the 58 enrolled (120 planned) patients. Median PFS was not improved in the UFT group compared with the OBS group (3.2 months versus 3.6 months, P = 0.752), as well as the median OS (14.2 months for both, P = 0.983). However, subgroup analysis showed that low baseline hemoglobin (< 120 g/L) was associated with poorer PFS with maintenance therapy (P = 0.032), while the normal hemoglobin patients benefit from the UFT treatment (P = 0.008). Grade 3 to 4 toxicities in the UFT group were anemia (3.4%), thrombocytopenia (3.4%) and diarrhea (6.9%). This trial did not show superiority of UFT maintenance in non-selected patients responding to fluorouracil-based first-line chemotherapy. The normal hemoglobin level at baseline is a predictive biomarker for favorable patient subsets from the maintenance treatment.

To assess the efficacy of polyethylene glycol 3350 plus electrolytes (PEG + E; Movicol) as oral monotherapy in the treatment of faecal impaction in children, and to compare PEG + E with lactulose as maintenance therapy in a randomised trial. An initial open-label study of PEG + E in the inpatient treatment of faecal impaction (phase 1), followed by a randomised, double-blind comparison between PEG + E and lactulose for maintenance treatment of constipation over a 3-month period (phase 2) in children aged 2 to 11 years with a clinical diagnosis of faecal impaction. Disimpaction on PEG + E was achieved in 58 (92%) of 63 of children (89% of 2-4 year olds and 94% of 5-11 year olds) without additional interventions. A maximum dose of 4 sachets (for 2-4 year olds) or 6 sachets (for 5-11 year olds) was required; median time to disimpaction was 6 days (range, 3-7 days). Seven children (23%) reimpacted whilst taking lactulose, whereas no children reimpacted while taking PEG + E (P = 0.011). The total incidence rate of adverse events seen was higher in the lactulose group (83%) than in the PEG + E group (64%). PEG + E is safe and highly effective in the management of childhood constipation. It allows a single orally administered laxative to be used for disimpaction without recourse to invasive interventions. It is significantly more effective than lactulose as maintenance therapy, both in efficacy in treating constipation and efficacy in preventing the recurrence of faecal impaction.

Adalimumab is a fully-human antibody that inhibits TNF alpha, with a significant efficacy for long-term maintenance of remission. Studies with this agent in Latin American Crohn's disease patients are scarce. The objective of this study was to outline clinical remission rates after 12 months of adalimumab therapy for Crohn's disease patients. Retrospective, single-center, observational study of a Brazilian case series of Crohn's disease patients under adalimumab therapy. Variables analyzed: demographic data, Montreal classification, concomitant medication, remission rates after 1, 4, 6 and 12 months. Remission was defined as Harvey-Bradshaw Index ≤ 4, and non-responder-imputation and last-observation-carried-forward analysis were used. The influence of infliximab on remission rates was analyzed by Fischer and Chi-square tests (P<0.05). Fifty patients, with median age of 35 years at therapy initiation, were included. Remission rates after 12 months of therapy were 54% under non-responder-imputation and 88% under last-observation-carried-forward analysis. After 12 months, remission on patients with previous infliximab occurred in 69.23% as compared to 94.59% in infliximab-naïve patients (P = 0.033). Adalimumab was effective in maintaining clinical remission after 12 months of therapy, with an adequate safety profile, and was also more effective in infliximab naïve patients.

The alarming increase in the prevalence of childhood obesity is recognised as a major public health concern. Currently, structured multi-modal therapy programmes present the gold standard of therapy strategies for obese children and adolescents. However, effects of these treatments are still a matter of discussion. Failure to isolate and understand the external and internal factors contributing to successful, long-term weight reduction may well be contributing to the ineffectiveness of current treatment interventions. A qualitative approach was chosen in order to identify subjectively perceived resources and barriers to weight maintenance after previous weight reduction. The research question focused on how these resources and barriers affect success of participants. Additionally the question arose as to how and to what extent parents should and could be involved in the therapy process. The results can deliver important starting points for the development of therapy programmes and future research. 7 participants of a weight reduction and maintenance programme and 7 of their parents were interviewed on their personal experiences during and after the treatment. The interviews were analysed based on the qualitative content analysis. Continuous motivation, especially after the initial weight reduction phase, was identified as the strongest predictor of successful weight maintenance. Successful weight maintainers generally showed characteristics of higher self-efficacy, internal motivation concerning physical activity and flexible self-control concerning food intake. Unsuccessful weight gainers stated a lack of motivation concerning physical activity and lost control over their eating habits. Concerning the role of parents in the therapy process, the results show that higher parental involvement does not predict greater success. The general relationship between parents and their children seems to be more significant, especially concerning the issues of responsibility. It is disputable to what extent the post treatment intervention contributed to the development of intrinsic motivation. More attention should be paid to the age (children or adolescents) of participants of therapy programmes, especially concerning the involvement of parents. It is assumed that general aspects of education should be discussed with parents. © Georg Thieme Verlag KG Stuttgart · New York.

Maintenance Cognitive Stimulation Therapy (CST) for dementia: A single-blind, multi-centre, randomized controlled trial of Maintenance CST vs. CST for dementia

PubMed Central

2010-01-01

Background Psychological treatments for dementia are widely used in the UK and internationally, but only rarely have they been standardised, adequately evaluated or systematically implemented. There is increasing recognition that psychosocial interventions may have similar levels of effectiveness to medication, and both can be used in combination. Cognitive Stimulation Therapy (CST) is a 7-week cognitive-based approach for dementia that has been shown to be beneficial for cognition and quality of life and is cost-effective, but there is less conclusive evidence for the effects of CST over an extended period. Methods/Design This multi-centre, pragmatic randomised controlled trial (RCT) to assess the effectiveness and cost-effectiveness of Maintenance CST groups for dementia compares a intervention group who receive CST for 7 weeks followed by the Maintenance CST programme once a week for 24 weeks with the control group who receive CST for 7 weeks, followed by treatment as usual for 24 weeks. The primary outcome measures are quality of life of people with dementia assessed by the QoL-AD and cognition assessed by the ADAS-Cog. Secondary outcomes include the person with dementia's mood, behaviour, activities of daily living, ability to communicate and costs; as well as caregiver health-related quality of life. Using a 5% significance level, comparison of 230 participants will yield 80% power to detect a standardised difference of 0.39 on the ADAS-Cog between the groups. The trial includes a cost-effectiveness analysis from a public sector perspective. Discussion A pilot study of longer-term Maintenance CST, offering 16 weekly sessions of maintenance following the initial CST programme, previously found a significant improvement in cognitive function (MMSE) for those on the intervention group. The study identified the need for a large-scale, multi-centre RCT to define the potential longer-term benefits of continuing the therapy. This study aims to provide definitive evidence of the potential efficacy of maintenance CST and establish how far the long-term benefits can be compared with antidementia drugs such as cholinesterase inhibitors.

The aims of this study were twofold: (1) to assess the marrow of patients with T-lineage acute lymphoblastic leukemia (T-ALL) for the presence of molecular residual disease (MRD) at different times after diagnosis and determine its value as a prognostic indicator; and (2) to compare the sensitivity, rapidity, and reliability of two methods for routine clinical detection of rearranged T-cell receptor (TCR). Marrow aspirates from 23 patients with T-ALL diagnosed consecutively from 1982 to 1994 at the Division of Pediatric Hematology and Oncology, University of Catania, Italy, were obtained at diagnosis, at the end of induction therapy (6 to 7 weeks after diagnosis), at consolidation and/or reinforced reinduction (12 to 15 weeks after diagnosis), at the beginning of maintenance therapy (34 to 40 weeks after diagnosis), and at the end of therapy (96 to 104 weeks after diagnosis). DNA from the patients' marrow was screened using the polymerase chain reaction (PCR) for the four most common TCR delta rearrangements in T-ALL (Vdelta1 Jdelta1, Vdelta2 Jdelta1, Vdelta3 Jdelta1, and Ddelta2 Jdelta1) and, when negative, further tested for the presence of other possible TCR delta and TCR gamma rearrangements. After identification of junctional rearrangements involving V, D, and J segments by DNA sequencing, clone-specific oligonucleotide probes 5' end-labeled either with fluorescein or with [gamma-32P]ATP were used for heminested PCR or dot hybridization of PCR products of marrows from patients in clinical remission. For 17 patients with samples that were informative at the molecular level, the estimated relapse-free survival (RFS) at 5 years was 48.6% (+/-12%). The sensitivity and specificity for detection of MRD relating to the outcome were 100% and 88.9% for the heminested fluorescence PCR and 71.4% and 88.9% for Southern/dot blot hybridization, respectively. Predictive negative and positive values were 100% and 90.7% for heminested fluorescence PCR, respectively. The probability of RFS based on evidence of MRD as detected by heminested fluorescence PCR at the time of initiation of maintenance therapy was 100% and 0% for MRD-negative and MRD-positive patients, respectively. Thus, the presence of MRD at the beginning of maintenance therapy is a strong predictor of poor outcome, and the molecular detection of MRD at that time might represent the basis for a therapeutic decision about such patients. By contrast, the absence of MRD at any time after initiation of treatment strongly correlates with a favorable outcome. The heminested fluorescence PCR appears to be more accurate and more rapid than other previously used methods for the detection of residual leukemia.

Impact of the ALMS and MAINTAIN trials on the management of lupus nephritis.

PubMed

Morris, Heather K; Canetta, Pietro A; Appel, Gerald B

2013-06-01

Current treatment of lupus nephritis consists of both induction and maintenance therapy, with the latter being designed to consolidate remissions and prevent relapses. Long-term maintenance treatment with intravenous cyclophosphamide was effective but associated with considerable toxicity. A small but well-designed controlled trial found that for post-induction maintenance therapy, both oral mycophenolate mofetil (MMF) and oral azathioprine were superior in efficacy and had reduced toxicity than a regimen of continued every third month intravenous cyclophosphamide. Although these oral agents were rapidly accepted and utilized as maintenance medications, their usage was based on scant evidence and there were no comparisons between the two. Recently, two relatively large, randomized, well-controlled, multicenter trials dealing with maintenance therapy for severe lupus nephritis have been completed. The Aspreva Lupus Management Study (ALMS) maintenance and MAINTAIN nephritis trials provide important information regarding the comparative efficacy and safety of MMF and azathioprine as maintenance therapies, as well as information on the effect of dosage and duration of treatment with these agents.

Evidence has suggested survival benefits of maintenance for advanced NSCLC patients not progressing after first-line chemotherapy. Additionally, particular first-line targeted therapies have shown survival improvements in selected populations. Optimal first-line and maintenance therapies remain unclear. Here, currently available evidence was synthesized to elucidate optimal first-line and maintenance therapy within patient groups. Literature was searched for randomized trials evaluating first-line and maintenance regimens in advanced NSCLC patients. Bayesian network meta-analysis was performed within molecularly and clinically selected groups. The primary outcome was combined clinically meaningful OS and PFS benefits. A total of 87 records on 56 trials evaluating first-line treatments with maintenance were included. Results showed combined clinically meaningful OS and PFS benefits with particular first-line with maintenance treatments, (1) first-line intercalated chemotherapy+erlotinib, maintenance erlotinib in patients with EGFR mutations, (2) first-line afatinib, maintenance afatinib in patients with EGFR deletion 19, (3) first-line chemotherapy + bevacizumab, maintenance bevacizumab in EGFR wild-type patients, (4) chemotherapy+conatumumab, maintenance conatumumab in patients with squamous histology, (5) chemotherapy+cetuximab, maintenance cetuximab or chemotherapy + necitumumab, maintenance necitumumab in EGFR FISH-positive patients with squamous histology, and (6) first-line chemotherapy+bevacizumab, maintenance bevacizumab or first-line sequential chemotherapy+gefitinib, maintenance gefitinib in patients clinically enriched for EGFR mutations with nonsquamous histology. No treatment showed combined clinically meaningful OS and PFS benefits in patients with EGFR L858R or nonsquamous histology. Particular first-line with maintenance treatments show meaningful OS and PFS benefits in patients selected by EGFR mutation or histology. Further research is needed to achieve effective therapy for patients with EGFR mutation L858R or nonsquamous histology. © 2017 The Authors. Cancer Medicine published by John Wiley & Sons Ltd.

Unconventional therapies for cancer: 1. Essiac

Kaegi, E

1998-01-01

Physicians and patients have been frustrated by the lack of reliable information on unconventional therapies. To help fill this gap in the area of breast cancer therapy, the Canadian Breast Cancer Research Initiative formed a task force to advise it on how best to promote research into unconventional therapies. As part of the work of the task force, a review of the available literature was carried out for each of the following products: Essiac, green tea, Iscador, hydrazine sulfate, vitamins A, C and E, and 714-X. The first article in this series on unconventional therapies for cancer describes the methodology used to obtain and evaluate the information and provides a summary of the findings on Essiac. Subsequent articles will cover the other products. For most of the products reviewed, there has been some indication of possible benefit but no definitive evidence. Innovative and collaborative research needed to meet the information needs of growing numbers of patients and their physicians is now being sponsored by the Canadian Breast Cancer Research Initiative. Open communication between patients and physicians is also necessary for the maintenance of an appropriate therapeutic partnership and for the identification and control of side effects. The Ontario Division of the Canadian Cancer Society, a partner in the Canadian Breast Cancer Research Initiative, supported the preparation of a patient-information piece on unconventional therapies to accompany the series. This item will assist patients who are considering such therapies and will promote open communication between patients and their physicians. PMID:9559016

Perioperative chemotherapy given to increase the chance of cure for localized disease, and maintenance therapy for metastatic disease, represent distinct aspects of the urothelial cancer disease treatment spectrum. The ability to access both pre and post chemotherapy tissue in the neoadjuvant setting provides important opportunities for translational research to test novel therapies and identify predictors of response to therapy. The maintenance setting may be more complex and study design and endpoints need to be determined based on the candidate drugs mechanism of action and toxicity. PMID:25987535

Ganciclovir. A pharmacoeconomic review of its use as intravenous or oral maintenance therapy in the management of cytomegalovirus retinitis in patients with AIDS.

PubMed

Perry, C M; Davis, R

1997-08-01

Cytomegalovirus retinitis, an opportunistic infection caused by the herpesvirus cytomegalovirus, is a major cause of illness in patients with advanced AIDS. As infected patients require long term drug treatment to delay disease progression and minimise loss of vision, the disease is associated with substantial treatment costs which considerably increase overall expenditure on AIDS-related health care. During the last decade, intravenous ganciclovir has been a mainstay of treatment for patients with cytomegalovirus retinitis. However, notwithstanding its demonstrated efficacy as maintenance therapy for this condition, long term intravenous drug administration is both inconvenient and uncomfortable for many patients. Moreover, neutropenia and catheter-related infections have been reported commonly in patients receiving ganciclovir via the intravenous route. To overcome the limitations of intravenous ganciclovir, an oral formulation of the drug has been developed for use as maintenance therapy. In comparative clinical trials, both intravenous and oral ganciclovir maintenance therapy slowed disease progression and preserved visual acuity in patients with stabilised cytomegalo-virus retinitis, although there was evidence that the intravenous formulation was more effective in terms of delaying recurrence of active disease. This suggests that oral ganciclovir use should be limited to the treatment of patients without evidence of immediately sight-threatening cytomegalovirus retinitis. Three published cost analyses, which were based on efficacy and tolerability data derived from 2 randomised, comparative clinical trials, have shown that oral ganciclovir maintenance therapy offers cost advantages over intravenous maintenance therapy, despite the higher acquisition cost of the oral formulation. The higher overall costs of intravenous maintenance treatment, compared with oral therapy, were attributed to higher drug administration and adverse event treatment costs. In one analysis, estimated lifetime treatment costs of oral maintenance therapy were 25.2% lower than those of intravenous maintenance treatment. As yet, no formal cost-effectiveness evaluations of oral and intravenous ganciclovir have been published. Few published data are available regarding the relative effects of intravenous and oral ganciclovir on quality of life. However, in a health state utility analysis, there was a large overall preference among HIV-infected individuals for oral over intravenous maintenance treatment. In conclusion, oral ganciclovir appears to be a cost-saving and patient-preferred alternative to its intravenous counterpart for the maintenance therapy of AIDS patients with stabilised cytomegalovirus retinitis in whom there is no evidence of sight-threatening disease.

Hedgehog signal transduction: key players, oncogenic drivers, and cancer therapy

PubMed Central

Pak, Ekaterina; Segal, Rosalind A.

2016-01-01

Summary The Hedgehog (Hh) signaling pathway governs complex developmental processes, including proliferation and patterning within diverse tissues. These activities rely on a tightly-regulated transduction system that converts graded Hh input signals into specific levels of pathway activity. Uncontrolled activation of Hh signaling drives tumor initiation and maintenance. However, recent entry of pathway-specific inhibitors into the clinic reveals mixed patient responses and thus prompts further exploration of pathway activation and inhibition. In this review, we share emerging insights on regulated and oncogenic Hh signaling, supplemented with updates on the development and use of Hh pathway-targeted therapies. PMID:27554855

We report a case of successful treatment of chronic hepatitis C infection with telaprevir-based triple therapy in a patient with hemophilia A complicated by factor VIII inhibitor. A twenty-two years old male with hereditary hemophilia A and high-titer factor VIII inhibitor was taking maintenance doses of recombinant factor VIII. He visited our clinic for treatment of his chronic hepatitis C with the newly instituted protease inhibitor based therapy. He was diagnosed with hepatitis C genotype 1a at one year of age. He was initiated on telaprevir, ribavirin and peg-interferon for treatment of hepatitis C and qualified for response-guided therapy. He completed treatment at 24 wk with minimal adverse effects. Notably, after 4 wk of hepatitis C treatment, his factor VIII inhibitor screen was negative and the dose for recombinant factor VIII decreased by half of the initial dosing before he was treated for hepatitis C. We suspect that suppressing hepatitis C may help decrease factor VIII inhibitor level and the need for recombinant factor VIII. PMID:24303477

The subsequent maintenance therapy in chronic hepatitis B (CHB) patients after long-term viral replication suppression is still uncertain. We aim to evaluate the efficacy of lamivudine (LAM) maintenance therapy in CHB patients achieving undetectable hepatitis B virus (HBV) DNA after 3 years of entecavir (ETV) therapy. Consecutive CHB patients who received at least 3 years of ETV and achieved HBV DNA negativity were allocated either LAM switch therapy or stopped ETV therapy in a prospective, open-label study. Another group of sex- and age-matched patients with continuous ETV therapy for at least 4 years served as historical control group. The primary outcome measurement of the study was relapse of HBV DNA (defined as serum HBV DNA level ≥ 2000 IU/mL). A total of 74 patients, including 42 of LAM switch and 32 of the nonswitch group, were enrolled. There were no significant differences in demographics, except a higher proportion of patients with positive hepatitis B envelope antigen in the nonswitch group at the initiation of ETV therapy. The LAM switch group had significantly lower 1-year relapse rate of HBV within 1 year compared to the nonswitch group (14.3% vs. 75%, p<0.001). However, none of the 48 historical control patients developed relapse of HBV, which was significantly lower than the rate in LAM switch group (p < 0.001). LAM switch was the only factor associated with HBV DNA relapse. In conclusion, continuous long-term potent nucleot(s)ide analogue therapy is mandatory for prevention of viral relapse in CHB patients.

Paramedic use of fixed-size lumen, gravity-controlled tubing to initiate intravenous infusions in the field may allow rapid start of neuroprotective therapy for acute stroke. In a large, multicenter trial, we evaluated its efficacy in attaining target serum levels of candidate neuroprotective agent magnesium sulfate and the relation of achieved magnesium levels to outcome. The FAST-MAG phase 3 trial (Field Administration of Stroke Therapy - Magnesium) randomized 1700 patients within 2 hours of onset to paramedic-initiated, a 15-minute loading intravenous infusion of magnesium or placebo followed by a 24-hour maintenance dose. The drug delivery strategy included fixed-size lumen, gravity-controlled tubing for field drug administration, and a shrink-wrapped ambulance kit containing both the randomized field loading and hospital maintenance doses for seamless continuation. Among patient randomized to active treatment, magnesium levels in the first 72 hours were assessed 987 times in 572 patients. Mean patient age was 70 years (SD±14 years), and 45% were women. During the 24-hour period of active infusion, mean achieved serum level was 3.91 (±0.8), consistent with trial target. Mg levels were increased by older age, female sex, lower weight, height, body mass index, and estimated glomerular filtration rate, and higher blood urea nitrogen, hemoglobin, and higher hematocrit. Adjusted odds for clinical outcomes did not differ by achieved Mg level, including disability at 90 days, symptomatic hemorrhage, or death. Paramedic infusion initiation using gravity-controlled tubing permits rapid achievement of target serum levels of potential neuroprotective agents. The absence of association of clinical outcomes with achieved magnesium levels provides further evidence that magnesium is not biologically neuroprotective in acute stroke. © 2017 American Heart Association, Inc.

Recent advances in post autologous transplantation maintenance therapies in B-cell non-Hodgkin lymphomas

2015-01-01

Lymphomas constitute the second most common indication for high dose therapy (HDT) followed by autologous hematopoietic cell transplantation (auto-HCT). The intent of administering HDT in these heterogeneous disorders varies from cure (e.g., in relapsed aggressive lymphomas) to disease control (e.g., most indolent lymphomas). Regardless of the underlying histology or remission status at transplantation, disease relapse remains the number one cause of post auto-HCT therapy failure and mortality. The last decade has seen a proliferation of clinical studies looking at prevention of post auto-HCT therapy failure with various maintenance strategies. The benefit of such therapies is in turn dependent on disease histology and timing of transplantation. In relapsed, chemosensitive diffuse large B-cell lymphoma (DLBCL), although post auto-HCT maintenance rituximab seems to be safe and feasible, it does not provide improved survival outcomes and is not recommended. The preliminary results with anti- programmed death -1 (PD-1) antibody therapy as post auto-HCT maintenance in DLBCL is promising but requires randomized validation. Similarly in follicular lymphoma, maintenance therapies including rituximab following auto-HCT should be considered investigational and offered only on a clinical trial. Rituximab maintenance results in improved progression-free survival but has not yet shown to improve overall survival in mantle cell lymphoma (MCL), but given the poor prognosis with post auto-HCT failure in MCL, maintenance rituximab can be considered on a case-by-case basis. Ongoing trials evaluating the efficacy of post auto-HCT maintenance with novel compounds (e.g., immunomodulators, PD-1 inhibitors, proteasome inhibitors and bruton’s tyrosine kinase inhibitors) will likely change the practice landscape in the near future for B cell non-Hodgkin lymphomas patients following HDT and auto-HCT.

308 nm excimer laser phototherapy is efficacious in the treatment of localized psoriasis. Different approaches regarding dose fluency, number of treatments, and maintenance have been utilized, and there is yet to be a consensus on standard protocol. To characterize treatment parameters for 308 nm excimer laser phototherapy. We performed a PubMed search for studies describing excimer laser treatment protocol with particular attention to dosage determination, dose adjustment, dose fluency, number of treatments, and maintenance. Seven prospective studies were found describing the excimer efficacy for psoriasis. All studies determined the initial treatment dose using either the minimal erythema dose (MED) or induration. Fluency ranged from 0.5 MED (low) to 16 MED (high); one study demonstrated that medium to high fluencies yielded better improvement in fewer number of treatments. Fluency adjustments during the course of treatment were important to minimize phototherapy-associated side effects. The use of higher fluencies was reported to result in higher occurrences of blistering. One study implemented a maintenance tapering of dose-frequency phase to better manage psoriasis flare-ups. The 308 nm excimer laser is an effective therapy for psoriasis regardless of the method used to determine initial dosage, dose fluency, or number of treatments. As its usage as a targeted monotherapy increases, future trials should consider evaluating and modifying these parameters to determine the most optimal management of localized psoriasis. Based on our reviewed studies, there is no consensus for a single excimer laser therapy protocol and as a result, patient preferences should continue to be an important consideration for phototherapy regimen planning.

The 2016 Conference on Retroviruses and Opportunistic Infections highlighted exciting advances in antiretroviral therapy, including important data on investigational antiretroviral drugs and clinical trials. Clinical trials demonstrated benefits from a long-acting injectable coformulation given as maintenance therapy, examined intravenous and subcutaneous administration of a monoclonal antibody directed at the CD4 binding site of HIV-1, and provided novel data on tenofovir alafenamide. Several studies focused on the role of HIV drug resistance, including the significance of minority variants, transmitted drug resistance, use of resistance testing, and drug class-related resistance. Novel data on the HIV care continuum in low- and middle-income settings concentrated on differentiated HIV care delivery models and outcomes. Data on progress toward reaching World Health Organization 90-90-90 targets as well as outcomes related to expedited initiation of HIV treatment and adherence strategies were presented. Results from a trial in Malawi showed reduced rates of mother-to-child transmission among HIV-infected women who initiated antiretroviral therapy prior to pregnancy, and several studies highlighted the effect of antiretroviral therapy in pediatric populations. A special session was dedicated to the findings of studies of Ebola virus disease and treatment during the outbreak in West Africa.

The last few years have witnessed a significant change in the treatment of Crohn's disease. Based on evidence from new clinical studies and recent meta-analyses, the role of and indications for conventional therapy have been reassessed. The 5-ASAs are nowadays less frequently used in both active disease and maintenance therapy. Instead, budesonide has been introduced in the treatment of mild-to-moderate ileal disease. Besides the modest use of 5-ASAs, steroids are prescribed for active colonic disease. Immunosuppressives, especially azathioprine, are more commonly used in moderate-to-severe disease as well as in maintenance. The preferred maintenance regimen following medically- and surgically-induced remission, in addition to relationship between medical and surgical therapies, has also changed. The recent introduction of new "biological" therapy represents a major, promising change in the therapy of resistant and penetrating disease.

There is evidence that Cognitive Stimulation Therapy and maintenance Cognitive Stimulation Therapy are effective in mild to moderate dementia. There is, however, little evidence available for its implementation in practice and the impact of outreach support on the sustainability of the programme. Two hundred and forty-one staff members were randomised from 63 dementia care settings between outreach support including an online forum, email, and telephone support, compared to usual Cognitive Stimulation Therapy control group. The primary outcome was average number of attendees to the Cognitive Stimulation Therapy and maintenance Cognitive Stimulation Therapy programmes. There was no difference in average number of attendees between the intervention and usual Cognitive Stimulation Therapy control groups for the Cognitive Stimulation Therapy (p = 0.82) or the maintenance Cognitive Stimulation Therapy programme (p = 0.97). Outreach support does not affect the average number of people with dementia attending the Cognitive Stimulation Therapy or maintenance Cognitive Stimulation Therapy programme. Irrespective of outreach support, the programmes remain widely implemented and yield perceived benefits for people with dementia. Copyright © 2017 John Wiley & Sons, Ltd.

In the Study to Investigate Real Life Effectiveness of Symbicort Maintenance and Reliever Therapy in Asthma Patients Across Asia, the effectiveness of single-inhaler budesonide/formoterol maintenance and reliever therapy was evaluated in patients with poorly controlled asthma. To study the effects of this therapy on a Chinese patient subgroup. In this 12-week, multicenter, open-label therapeutic phase IV study, patients with partially controlled or uncontrolled asthma were switched from their usual asthma treatment to budesonide/formoterol (160/4.5 μg, one inhalation twice daily and as needed) after a 2-week run-in period. Primary and secondary objectives of the study, asthma control and quality of life were assessed by using the five-item Asthma Control Questionnaire and the Standardized Asthma Quality of Life Questionnaire. Asthma symptom scores, study medication use, asthma control and/or symptom-free days, and the number of asthma-related nighttime awakenings were also monitored. In total, 478 Chinese patients were enrolled and 407 patients initiated treatment. The patients displayed a significant improvement in mean (standard deviation) five-item Asthma Control Questionnaire (-0.58 ± 0.86; p < 0.0001) and Standardized Asthma Quality of Life Questionnaire (0.69 ± 0.79; p < 0.0001) scores versus the run-in period. Mean (standard deviation) asthma symptom scores were significantly reduced compared with run-in (-0.30 ± 0.55 daytime, -0.31 ± 0.56 nighttime; p < 0.0001 for both), as was as-needed study medication use (-0.24 ± 1.16 daytime, -0.28 ± 0.97 nighttime; p < 0.0001 for both). Patients who received previous treatment with salmeterol/fluticasone propionate also showed improvement in asthma control. In China, asthma control in Chinese patients whose asthma was not fully controlled with previous standard therapy improved during 12 weeks of treatment with budesonide/formoterol maintenance and reliever therapy. Quality of life was improved, and treatment was well tolerated. (Clinical Trials identifier NCT00939341).

[Adaptive desensitization for acetylsalicylic acid hypersensitivity: A success story?].

PubMed

Mühlmeier, G; Hausch, R; Maier, H

2015-10-01

Adaptive desensitization still remains the only causative therapy for acetylsalicylic acid (ASA) hypersensitivity and is carried out nearly worldwide. To date there are hardly any data available on disease development under current desensitization therapy and longitudinal data in particular are missing. Out of a large collective of patients with proven hypersensitivity to ASA, 194 patients with initiated desensitization treatment were observed for periods up to 5 years (average 32 months). Patients with immediate reactions to systemic challenge tests revealed a response rate of 77% after 12 months of therapy. In this period 12% reached complete remission, 38% showed a clear reduction in symptoms, 32% reached partial remission, 13% remained unchanged and 5% suffered from disease progression. Adaptive desensitization therapy for hypersensitivity to ASA has been shown to be an effective causative therapy and chronic hyperplastic sinusitis as well as bronchial asthma could be improved. For the determination of maintenance dosages and required time periods more data are needed.

Malignant brain tumors are among the most lethal cancers, and conventional therapies are largely limited to palliation. Novel therapies targeted against specific molecular pathways may offer improved efficacy and reduced toxicity compared to conventional therapies, but initial clinical trials of molecular targeted agents in brain cancer therapy have been frequently disappointing. In brain tumors and other cancers, subpopulations of tumor cells have recently been characterized by their ability to self-renew and initiate tumors. Although these cancer stem cells, or tumor initiating cells, are often only present in small numbers in human tumors, mounting evidence suggests that cancer stem cells contribute to tumor maintenance and therapeutic resistance. Thus, the development of therapies that target cancer stem cell signal transduction and biologies may improve brain tumor patient survival. We now demonstrate that populations enriched for cancer stem cells are preferentially sensitive to an inhibitor of Akt, a prominent cell survival and invasion signaling node. Treatment with an Akt inhibitor more potently reduced the numbers of viable brain cancer stem cells relative to matched non-stem cancer cells associated with a preferential induction of apoptosis and a suppression of neurosphere formation. Akt inhibition also reduced the motility and invasiveness of all tumor cells but had a greater impact on cancer stem cell behaviors. Furthermore, inhibition of Akt activity in cancer stem cells increased survival of immunocompromised mice bearing human glioma xenografts in vivo. Together, these results suggest that Akt inhibitors may function as effective anti-cancer stem cell therapies. PMID:18802038

Abstract Currently, there are few guidelines for the use of vitamin K1 in the maintenance treatment of long-acting anticoagulant rodenticide (LAAR) poisonings. We explored factors in the treatment of LAAR poisoning during the maintenance period in order to suggest feasible treatment models. Data from 24 cases of anticoagulant rodenticide poisoning in our hospital were collected from January 2013 to May 2016. The patients’ sex, age, coagulation function, total time from poisoning to treatment with vitamin K1 (prehospital time), vitamin K1 sustained treatment time (VKSTT), anticoagulant rodenticide category, and specific poison dosage were collected. Multivariate analysis was used to evaluate the correlation between vitamin K1 dosage and other factors during the maintenance period. Only VKSTT (partial regression coefficient −1.133, 0.59, P = 0.035) had an obvious influence on the therapeutic dose of vitamin K1 required during the maintenance period. After an initial pulse therapy, the bleeding and coagulation functions were stabilized, and the patients were subsequently treated with vitamin K1 during the maintenance period. Over time, the maintenance dose of vitamin K1 (10–120 mg/d, intravenous drip) was gradually decreased and was not related to toxicant concentration. PMID:28002326

Purpose Elderly patients with acute myeloid leukemia (AML) have a poor prognosis, and innovative maintenance therapy could improve their outcomes. Androgens, used in the treatment of aplastic anemia, have been reported to block proliferation of and initiate differentiation in AML cells. We report the results of a multicenter, phase III, randomized open-label trial exploring the benefit of adding androgens to maintenance therapy in patients 60 years of age or older. Patients and Methods A total of 330 patients with AML de novo or secondary to chemotherapy or radiotherapy were enrolled in the study. Induction therapy included idarubicin 8 mg/m 2 on days 1 to 5, cytarabine 100 mg/m 2 on days 1 to 7, and lomustine 200 mg/m 2 on day 1. Patients in complete remission or partial remission received six reinduction courses, alternating idarubicin 8 mg/m 2 on day 1, cytarabine 100 mg/m 2 on days 1 to 5, and a regimen of methotrexate and mercaptopurine. Patients were randomly assigned to receive norethandrolone 10 or 20 mg/day, according to body weight, or no norethandrolone for a 2-year maintenance therapy regimen. The primary end point was disease-free survival by intention to treat. Secondary end points were event-free survival, overall survival, and safety. This trial was registered at www.ClinicalTrials.gov identifier NCT00700544. Results Random assignment allotted 165 patients to each arm; arm A received norethandrolone, and arm B did not receive norethandrolone. Complete remission or partial remission was achieved in 247 patients (76%). The Schoenfeld time-dependent model showed that norethandrolone significantly improved survival for patients still in remission at 1 year after induction. In arms A and B, respectively, 5-year disease-free survival was 31.2% and 16.2%, event-free survival was 21.5% and 12.9%, and overall survival was 26.3% and 17.2%. Norethandrolone improved outcomes irrelevant to all prognosis factors. Only patients with baseline leukocytes > 30 × 10 9 /L did not benefit from norethandrolone. Conclusion This study demonstrates that maintenance therapy with norethandrolone significantly improves survival in elderly patients with AML without increasing toxicity.

Discontinuation of Buprenorphine Maintenance Therapy: Perspectives and Outcomes

PubMed Central

Bentzley, Brandon S.; Barth, Kelly S.; Back, Sudie E.; Book, Sarah W.

2015-01-01

Buprenorphine maintenance therapy (BMT) is increasingly the preferred opioid maintenance agent due to its reduced toxicity and availability in an office-based setting in the United States. Although BMT has been shown to be highly efficacious, it is often discontinued soon after initiation. No current systematic review has yet investigated providers’ or patients’ reasons for BMT discontinuation or the outcomes that follow. Hence, provider and patient perspectives associated with BMT discontinuation after a period of stable buprenorphine maintenance and the resultant outcomes were systematically reviewed with specific emphasis on pre-buprenorphine-taper parameters predictive of relapse following BMT discontinuation. Few identified studies address provider or patient perspectives associated with buprenorphine discontinuation. Within the studies reviewed providers with residency training in BMT were more likely to favor long term BMT instead of detoxification, and providers were likely to consider BMT discontinuation in the face of medication misuse. Patients often desired to remain on BMT because of fear of relapse to illicit opioid use if they were to discontinue BMT. The majority of patients who discontinued BMT did so involuntarily, often due to failure to follow strict program requirements, and 1 month following discontinuation, rates of relapse to illicit opioid use exceeded 50% in every study reviewed. Only lower buprenorphine maintenance dose, which may be a marker for attenuated addiction severity, predicted better outcomes across studies. Relaxed BMT program requirements and frequent counsel on the high probability of relapse if BMT is discontinued may improve retention in treatment and prevent the relapse to illicit opioid use that is likely to follow BMT discontinuation.

Atrial fibrillation (AF) is the most prevalent cardiac arrhythmia and is associated with significant morbidity and mortality. Obstructive sleep apnoea (OSA) is common among patients with AF. Growing evidence suggests that OSA is associated with the initiation and maintenance of AF. This association is independent of obesity, body mass index and hypertension. OSA not only promotes initiation of AF but also has a significant negative impact on the treatment of AF. Patients with untreated OSA have a higher AF recurrence rate with drug therapy, electrical cardioversion and catheter ablation. Treatment with continuous positive airway pressure (CPAP) has been shown to improve AF control in patients with OSA. In this article, we will review and discuss the pathophysiological mechanisms of OSA that may predispose OSA patients to AF as well as the standard and emerging therapies for patients with both OSA and AF.

The effect of budesonide/formoterol maintenance and reliever therapy on the risk of severe asthma exacerbations following episodes of high reliever use: an exploratory analysis of two randomised, controlled studies with comparisons to standard therapy

PubMed Central

2012-01-01

Background Divergent strategies have emerged for the management of severe asthma. One strategy utilises high and fixed doses of maintenance treatment, usually inhaled corticosteroid/long-acting β2-agonist (ICS/LABA), supplemented by a short-acting β2-agonist (SABA) as needed. Alternatively, budesonide/formoterol is used as both maintenance and reliever therapy. The latter is superior to fixed-dose treatment in reducing severe exacerbations while achieving similar or better asthma control in other regards. Exacerbations may be reduced by the use of budesonide/formoterol as reliever medication during periods of unstable asthma. We examined the risk of a severe exacerbation in the period after a single day with high reliever use. Methods Episodes of high reliever use were quantified and exacerbations occurring post-index day with these episodes were examined post hoc in two double-blind studies comparing the efficacy and safety of budesonide/formoterol maintenance and reliever therapy (Symbicort SMART™, Turbuhaler®) 160/4.5 μg twice daily plus as needed with similar or higher maintenance doses of ICS/LABA plus SABA or formoterol. Results Budesonide/formoterol maintenance and reliever therapy significantly reduced the risk of episodes of high reliever use (>6 inhalations/day) vs. all alternative ICS/LABA regimens. With conventional fixed-dose treatment the need for exacerbation treatment within 21 days ranged from 6.0–10.1% of days post-index for all regimens compared with 2.5–3.4% of days with budesonide/formoterol maintenance and reliever therapy. Conclusions Budesonide/formoterol maintenance and reliever therapy reduces the incidence of high reliever episodes and the exacerbation burden immediately following these episodes vs. alternative ICS/LABA plus SABA regimens at up to double the maintenance dose of ICS. Trial registration These studies do not have registration numbers as they were conducted before clinical trial registration was required PMID:22816878

The Japanese Society of Gastroenterology (JSGE) revised the evidence-based clinical practice guidelines for peptic ulcer disease in 2014 and has created an English version. The revised guidelines consist of seven items: bleeding gastric and duodenal ulcers, Helicobacter pylori (H. pylori) eradication therapy, non-eradication therapy, drug-induced ulcer, non-H. pylori, non-nonsteroidal anti-inflammatory drug (NSAID) ulcer, surgical treatment, and conservative therapy for perforation and stenosis. Ninety clinical questions (CQs) were developed, and a literature search was performed for the CQs using the Medline, Cochrane, and Igaku Chuo Zasshi databases between 1983 and June 2012. The guideline was developed using the Grading of Recommendations Assessment, Development and Evaluation (GRADE) system. Therapy is initially provided for ulcer complications. Perforation or stenosis is treated with surgery or conservatively. Ulcer bleeding is first treated by endoscopic hemostasis. If it fails, surgery or interventional radiology is chosen. Second, medical therapy is provided. In cases of NSAID-related ulcers, use of NSAIDs is stopped, and anti-ulcer therapy is provided. If NSAID use must continue, the ulcer is treated with a proton pump inhibitor (PPI) or prostaglandin analog. In cases with no NSAID use, H. pylori-positive patients receive eradication and anti-ulcer therapy. If first-line eradication therapy fails, second-line therapy is given. In cases of non-H. pylori, non-NSAID ulcers or H. pylori-positive patients with no indication for eradication therapy, non-eradication therapy is provided. The first choice is PPI therapy, and the second choice is histamine 2-receptor antagonist therapy. After initial therapy, maintenance therapy is provided to prevent ulcer relapse.

Barriers and Facilitators of Breastfeeding Reported by Postpartum Women in Methadone Maintenance Therapy.

This study utilized a cross-sectional qualitative and quantitative interview-based survey to capture the infant feeding practices and barriers to exclusive breastfeeding for women in methadone maintenance therapy. Participants were recruited from an opioid dependence treatment center in an urban setting in the Southeastern United States. A convenience sample of women in treatment (n = 30) were interviewed using an adapted instrument designed to capture decisions and intentions to formula feed or breastfeed; support from friends and family; hospital experience; support from healthcare personnel; and maternal knowledge of breastfeeding while taking methadone. The majority of women in the sample initiated breastfeeding, but only 10% continued for >1 month. Challenges related to infant hospital stay posed a significant barrier. Two-thirds of infants remained hospitalized after the mother was discharged. Out of the 24 women who initiated breastfeeding, 11 reported that they discontinued because of issues related to infant's neonatal intensive care unit (NICU) stay. Eleven women reported that their healthcare providers did not discuss breastfeeding with them. Women who were encouraged to breastfeed by healthcare staff were more likely to breastfeed for longer durations. Women in treatment for opioid dependence both desire and attempt to establish breastfeeding, but encounter significant challenges, including long NICU stays and lack of support and education, that compromise their success. These findings should inform the development of future programs or interventions geared toward increasing breastfeeding initiation, support, and duration among women who give birth to babies while in treatment for opioid addiction.

Patterns of care following topical testosterone agent (TTA) initiation are poorly understood. This study aimed to characterize care following TTA initiation and compare results between patients with and without a serum testosterone (T) assay within 30 days before and including TTA initiation. Adult men (N=4,146) initiating TTAs from January 1, 2011, to March 31, 2012, were identified from a commercially insured database. Patients were included if they initiated at recommended starting dose (RSD) and had ≥12 and ≥6 months of continuous eligibility preinitiation (baseline) and postinitiation (study period), respectively. Patients were stratified by preinitiation T assay. Maintenance dose attainment month was determined using unadjusted generalized estimating equations regression to compare dose relative to RSD month by month. Outcomes included maintenance dose attainment month, time to stopping of index TTA refills or a claim for nonindex testosterone replacement therapy (TRT), and proportion of patients with study period T assay or diagnosis of hypogonadism (HG) or another low testosterone condition, and were compared using chi-square and Wilcoxon rank-sum tests for categorical and continuous variables, respectively. Maintenance dose was attained in Month 4 postinitiation, at 115.2% of RSD. Approximately 46% of patients had a preinitiation T assay; these men were more likely to receive a diagnosis of HG or another low testosterone condition, to have a follow-up T assay, to continue treatment by filling a nonindex TRT, and less likely to stop refilling treatment with their index TTA. Differences in care following TTA initiation suggest that preinitiation T assays (i.e., guideline-based care) may be helpful in ensuring treatment benefits. © The Author(s) 2014.

Post-autologous transplant maintenance therapies in lymphoid malignancies: are we there yet?

2015-11-01

Disease relapse after autologous hematopoietic transplant (auto-HCT) remains the number one cause of post-transplant therapy failure and mortality. The last decade has seen a proliferation of clinical studies looking at the prevention of post-auto-HCT therapy failure with various maintenance strategies. The benefit of such therapies is in turn dependent on disease histology and timing of transplantation. Although high dose therapy (HDT) provides durable responses in chemosensitive relapsed diffuse large B-cell lymphoma (DLBCL), a sizable subset experiences disease relapse. Unfortunately, the addition of rituximab as a post-auto-HCT maintenance strategy did not improve survival outcomes. The preliminary results with programmed death -1 (PD-1) Ab as post-auto maintenance in DLBCL is promising but requires randomized validation. In follicular lymphoma, the 5- and 10-year PFS rates are ~60% and 31%, respectively. Although the addition of rituximab improved PFS, there is no survival benefit, to date. Disease relapse after auto-HCT in mantle cell lymphoma (MCL) is not uncommon. Rituximab maintenance in this setting provides a PFS benefit. Given the poor prognosis of post-auto-HCT failures in MCL, maintenance can be considered on a case-by-case basis. In chemosensitive relapsed Hodgkin lymphoma, addition of brentuximab vedotin after auto-HCT improved 2-year PFS (65 vs 45%) and can be considered as an option for maintenance therapy post auto-HCT, in select higher risk patients. Ongoing trials evaluating the efficacy of post-auto-HCT maintenance with novel agents (for example, immunomodulators, proteasome inhibitors, PD-1 inhibitors, Bruton's tyrosine kinase inhibitors and so on) will likely change the practice landscape for lymphoma patients following HDT and auto-HCT.

Severe colitis flare from ulcerative colitis (UC) or Crohn's disease (CD) may be refractory to corticosteroids and antitumour necrosis factor (TNF) agents resulting in high colectomy rates. We aimed to describe the utility of tacrolimus to prevent colectomy during second-line vedolizumab initiation after corticosteroid and anti-TNF treatment failure in paediatric severe colitis. A retrospective cohort analysis was performed between 1 October 2014 and 31 October 2016 at a single tertiary care centre. Inclusion criteria were patients with severe colitis who received tacrolimus before or during vedolizumab induction and previous exposure to anti-TNF therapy with or without corticosteroids. The initiation of tacrolimus was clinician dependent based on an institutional protocol. Twelve patients (10 UC, two CD; median age 16 years; three female) received at least one dose of vedolizumab 10 mg/kg (max of 300 mg) due to anti-TNF therapy failure and persistent flare not responsive to corticosteroids. Of the 12 patients, eight (67%) and four (33%) had failed one or two anti-TNF agents, respectively. Tacrolimus was initiated for acute disease severity during hospitalisation (58%) or ongoing flare during outpatient care (42%). 9 (75%) of 12 patients avoided colectomy or inflammatory bowel disease-related surgery at 24 weeks and eight (68%) continued on vedolizumab maintenance with no adverse events out to 80 weeks. We report real-world data on the outcome of tacrolimus around vedolizumab initiation in paediatric UC or CD after corticosteroid and anti-TNF therapy treatment failure. Our pilot experience indicates a potential benefit of concomitant tacrolimus when initiating vedolizumab therapy.

Numerous studies have documented the clinical outcomes of laser therapy for untreated periodontitis, but very few have reported on lasers treating inflamed pockets during maintenance therapy. The aim of this study is to compare the effectiveness of scaling and root planing (SRP) plus the adjunctive use of diode laser therapy to SRP alone on changes in the clinical parameters of disease and on the gingival crevicular fluid (GCF) inflammatory mediator interleukin-1β (IL-1β) in patients receiving regular periodontal maintenance therapy. This single-masked and randomized, controlled, prospective study includes 22 patients receiving regular periodontal maintenance therapy who had one or more periodontal sites with a probing depth (PD) ≥ 5 mm with bleeding on probing (BOP). Fifty-six sites were treated with SRP and adjunctive laser therapy (SRP + L). Fifty-eight sites were treated with SRP alone. Clinical parameters, including PD, clinical attachment level (CAL), and BOP, and GCF IL-1β levels were measured immediately before treatment (baseline) and 3 months after treatment. Sites treated with SRP + L and SRP alone resulted in statistically significant reductions in PD and BOP and gains in CAL. These changes were not significantly different between the two therapies. Similarly, differences in GCF IL-1β levels between SRP + L and SRP alone were not statistically significant. In periodontal maintenance patients, SRP + L did not enhance clinical outcomes compared to SRP alone in the treatment of inflamed sites with ≥ 5 mm PD.

Papillon-Lefèvre syndrome (PLS) is a rare autosomal recessive condition manifested clinically by hyperkeratosis of the palms and soles and rapidly progressive periodontitis resulting in loss of deciduous and permanent teeth. This case report describes the clinical periodontal findings and treatment of a 10-year-old male patient with PLS. The patient provided informed consent, and the study was conducted in accordance with the Helsinki Declaration of 1975, as revised in 2000. Upon initial presentation, a full periodontal examination was completed. Conventional probing depths, clinical attachment levels (CAL), gingival index (GI), and plaque index (PI) were measured prior to initial therapy, which involved oral hygiene instruction and scaling and root planing. At reevaluation, initial treatment proved unsuccessful, and a surgical approach with concomitant systemic antibiotic therapy was implemented. In addition, the patient's dermatologist treated his palmoplantar keratoderma with systemic retinoids. Subsequently, the patient was placed on a strict 3-month maintenance protocol and was evaluated over a period of 1 year. Initial treatment with mechanical therapy, oral hygiene instruction, frequent recalls, and systemic antibiotics did not yield efficacious results. However, with the addition of surgical treatment, a favorable clinical outcome was obtained. Numerous treatment regimens for the periodontal disease seen in PLS can be found in the literature. We demonstrate successful treatment of the periodontal disease seen in this condition using mechanical therapy, systemic antibiotics, and surgical modalities; over a period of 1 year, we were able to achieve significant reductions in gingival inflammation and erythema.

In January 2014 to February 2016, fifty-two MM patients (19 men and 33 women) aged 24 to 66 years (median 54 years), who had achieved CR after auto-HSCT, were randomized to perform maintenance therapy with bortezomib during a year. On day 100 after auto-HSCT, all the patients underwent immunophenotyping of bone marrow plasma cells by 6-color flow cytometry to detect MRD. Relapse-free survival (RFS) was chosen as a criterion for evaluating the efficiency of maintenance therapy. After auto-HSCT, MRD-negative patients had a statistically significantly higher 2-year RFS rate than MRD-positive patients: 52.9% (95% confidence interval (CI), 35.5 to 70.5%) versus 37.2% (95% CI, 25.4 to 49.3%) (p=0.05). The presence of MRD statistically significantly increased the risk of relapse (odds ratio 1.7; 95% CI, 1.2 to 3.4; p=0.05). Two-year cumulative risk of relapse (using the Kaplan-Meier) after auto-HSCT did not statistically significantly differ in MRD-negative patients receiving (n=15) and not receiving (n=10) maintenance therapy with bortezomib (p=0.58). After completion of maintenance treatment, 42% of the MRD-positive patients achieved a negative status. In the MRD-positive patients who had received maintenance therapy, the average time to recurrence was 5 months longer than that in the naïve patients: 17.3 versus 12.3 months. The MRD status determined in MM patients who have achieved CR after auto-HSCT is an important factor for deciding on the use of maintenance therapy.

Generalized aggressive periodontitis (GAgP) encompasses a distinct type of periodontal disease exhibiting much more rapid periodontal tissue destruction than chronic periodontitis. The best method for management of GAgP may include the use of both regenerative periodontal techniques and the administration of systemic antibiotics. The treatment of a case of GAgP over a period of 6.7 years is presented in this case report. Initial periodontal therapy (week 1- 32) consisted of supragingival plaque control and three appointments of scaling and root planing. Based on the periodontal pathogens isolated (5 species), the patient also received metronidazole plus amoxicillin for one week, followed 10 weeks later by metronidazole plus amoxicillin/clavulanate for one week. The patient was put on regular supportive periodontal therapy (SPT) thereafter. Orthodontic treatment was performed after completion of the initial therapy for 96 weeks. Measurements of clinical attachment level, bleeding on probing and plaque index were obtained at every examination. Antimicrobial and mechanical treatment resulted in eradication of all periopathogens and significantly improved all clinical parameters. During orthodontic treatment and active maintenance, there was no relapse of GAgP. The patient participated in SPT for 194 weeks and thereafter decided to discontinue SPT. Twenty-four months later a relapse of GAgP was diagnosed and all teeth had to be extracted. These results indicate that a combined mechanical and antimicrobial treatment approach can lead to consistent resolution of GAgP. Further studies including a larger number of cases are warranted to validate these findings.

Ning Shoucheng; Knox, Susan J.

2006-06-01

Purpose: The primary objective was to optimize the combined treatment regimen using arsenic trioxide (ATO) and fractionated radiotherapy for the treatment of malignant glioma. Methods and Materials: Nude mice with human glioma xenograft tumors were treated with fractionated local tumor radiation of 250 cGy/fraction/day and 5 mg/kg ATO for 5-10 days. Results: Time course experiments demonstrated that maximal tumor growth delay occurred when ATO was administered between 0 and 4 h after radiation. The combination treatment of ATO and radiation synergistically inhibited tumor growth and produced a tumor growth delay time of 13.2 days, compared with 1.4 days and 6.5more » days for ATO and radiation alone (p < 0.01), respectively. The use of concurrent therapy of radiation and ATO initially, followed by ATO as maintenance therapy, was superior to the use of preloading with ATO before combined therapy and produced a tumor growth delay time of 22.7 days as compared with 11.7 days for the ATO preloading regimen (p < 0.01). The maintenance dose of ATO after concurrent therapy was effective and important for continued inhibition of tumor growth. Conclusions: The combined use of fractionated radiation and ATO is effective for the treatment of glioma xenograft tumors. ATO was most effective when administered 0-4 h after radiation without pretreatment with ATO. These results have important implications for the optimization of treatment regimen using ATO and fractionated radiotherapy for the treatment of brain tumors.« less

Evidence-based medical oncology and interventional radiology paradigms for liver-dominant colorectal cancer metastases

Sag, Alan Alper; Selcukbiricik, Fatih; Mandel, Nil Molinas

2016-01-01

Colorectal cancer metastasizes predictably, with liver predominance in most cases. Because liver involvement has been shown to be a major determinant of survival in this population, liver-directed therapies are increasingly considered even in cases where there is (limited) extrahepatic disease. Unfortunately, these patients carry a known risk of recurrence in the liver regardless of initial therapy choice. Therefore, there is a demand for minimally invasive, non-surgical, personalized cancer treatments to preserve quality of life in the induction, consolidation, and maintenance phases of cancer therapy. This report aims to review evidence-based conceptual, pharmacological, and technological paradigm shifts in parenteral and percutaneous treatment strategies as well as forthcoming evidence regarding next-generation systemic, locoregional, and local treatment approaches for this patient population.

Colorectal carcinoma (CRC) is one of the most frequently diagnosed cancers and the leading cause of cancer-related death for both men and women. Recent studies have revealed that a small sub-population of cancer cells, termed cancer stem-like cells (CSCs)/cancer-initiating cells (CICs), are endowed with tumor-initiating ability, self-renewal ability and differentiation ability. CSCs/CICs are resistant to current therapies including chemotherapy and radiotherapy. Thus, CSCs/CICs are responsible for recurrence and metastasis, and eradication of CSCs/CICs is essential to cure cancer. In this study, we isolated CR-CSCs/CICs as sphere-cultured cells and found that a product derived from LY6/PLAUR domain containing 3 (LYPD3) ismore » preferentially expressed in CSCs/CICs. Gene overexpression and gene knockdown experiments revealed that LYPD3 has a role in the maintenance of CR-CSCs/CICs. The findings provide a novel molecular insight into CR-CSCs/CICs.« less

Atopic dermatitis (AD) affects health and quality of life and it has great impact on both health-care costs and costs to the society. The objective of this study was to develop a model to analyse the cost-effectiveness of a barrier-strengthening moisturizing cream as maintenance therapy compared with no treatment after initial treatment with betamethasone valerate in adult patients with AD in Sweden. A further aim was to apply a similar health-economic analysis for Denmark, Norway and Finland. A Markov simulation model was developed including data from three sources: (i) efficacy data from a randomized controlled trial including patients with moderate AD treated with either a moisturizing cream or no treatment, (ii) resource utilization and quality of life data, and (iii) unit prices from official price lists. A societal perspective was used and the analysis was performed according to treatment practice in Sweden. The model simulation was also applied for Denmark, Norway and Finland with inclusion of country-specific unit costs. Sensitivity analyses were performed to test the robustness of the results. The results from the present analyses of treatment for patients with moderate AD indicate that maintenance treatment with a moisturizing cream during eczema-free periods could be cost-effective in a societal perspective. Similar results were obtained for Sweden, Denmark, Norway and Finland. According to the analysis, treatment with a moisturizing cream was found to be a cost-effective option compared with no treatment in eczema-free periods in adult patients with AD in the four Nordic countries.

Recent Advances in Targeted Therapy for Glioma.

2017-01-01

Gliomas are the most common primary malignant brain tumors, which have a universally fatal outcome. Current standard treatment for glioma patients is surgical removal followed by radiotherapy and adjuvant chemotherapy. Due to therapeutic resistance and tumor recurrence, efforts are ongoing to identify the molecules that are fundamental to regulate the tumor progression and provide additional methods for individual treatment of glioma patients. By studying the initiation and maintenance of glioma, studies focused on the targets of tyrosine kinase receptors including EGFR, PDGFR and other crucial signal pathways such as PI3K/AKT and RAS/RAF/MAPK pathway. Furthermore, recent advances in targeting immunotherapy and stem cell therapy also brought numerous strategies to glioma treatment. This article reviewed the researches focused on the advanced strategies of various target therapies for improving the glioma treatment efficacy, and discussed the challenges and future directions for glioma therapy.

Maintenance therapy for colorectal cancer: which regimen and which patients?

PubMed

Mikhail, Sameh; Bekaii-Saab, Tanios

2015-11-01

The introduction of therapeutic agents such as irinotecan, oxaliplatin, and more recently biologic agents such as vascular endothelial growth factor and epidermal growth factor receptor (EGFR) inhibitors has significantly improved survival of patients with metastatic colorectal cancer. These novel agents have also contributed to added toxicities. Therefore, several studies have evaluated the role of maintenance therapy with less intensive regimens in patients who experienced stable disease or treatment response following induction therapy as a strategy to reduce toxicity and improve quality of life. The success of such strategies, however, requires assurance that their survival would not be compromised. We therefore reviewed studies that have explored the various strategies of treatment de-escalation with an emphasis on survival and toxicity outcomes. Recent studies evaluated the role of maintenance therapy with chemotherapy only, chemotherapy plus bevcizumab, bevacizumab only, and EGFR inhibitors. Current evidence suggests that maintenance strategies offer significant benefit to patients by providing continuous clinical benefit while minimizing the risks associated with continuous therapy. Strategies to improve selection of patients for maintenance therapy versus identifying subgroups of patients that will benefit from a chemotherapy-free interval need to continue to be studied. Finally, as our understanding of the molecular and genetic drivers of colorectal cancer continues to expand, refining these strategies to include more target-specific agents should become more routine.

Little is known about the financial costs that smoking adds to the life-time treatment of periodontal disease. The total life-time cost of periodontal treatment was modelled using data from private periodontal practice. The costs of initial and supportive therapy, re-treatment and tooth replacements (with bridgework or implants) were identified using average dental charges from the American Dental Association survey. Smoking costs at $6 and $10 for 20 cigarettes were compared to the costs of life-time periodontal treatment for stable and unstable compliant patients. Smoking added 8.8% to the financial cost of the life-time cost of periodontal therapy in stable maintenance patients, 40.1% in patients who needed one extra maintenance visit and 71.4% in patients who needed two extra maintenance visits per year in addition to added re-treatment. The cost of smoking far exceeded the cost of periodontal treatment; For patients who smoked 10 to 40 cigarettes per day at the cost of $6 or $10 a pack, the cost of smoking exceeded the cost of life-time periodontal treatment by between 2.7 and 17.9 times. Smoking 40 cigarettes at $10 a packet for 3.4 years would pay for the entire life-time cost of periodontal treatment. Smoking adds considerable extra financial costs to the life-time treatment of periodontal diseases. The cost of smoking itself exceeds the cost of periodontal therapy.

Purpose A recent phase III study (PARAMOUNT) demonstrated that pemetrexed continuation maintenance therapy is a new treatment paradigm for advanced nonsquamous non-small cell lung cancer (NSCLC). The majority of patients enrolled in PARAMOUNT were Caucasian (94%). We reviewed efficacy and safety data from two clinical trials, which enrolled East Asian (EA) patients, to supplement data from PARAMOUNT on pemetrexed continuation maintenance therapy in patients with nonsquamous NSCLC. Materials and Methods Study S110 was a phase II, multicenter, randomized, controlled, open-label trial in never-smoker, chemonaïve, EA patients (n=31) with locally advanced or metastatic nonsquamous NSCLC (n=27). Study JMII was a multicenter, open-label, single-arm, post-marketing, clinical trial in Japanese patients (n=109) with advanced nonsquamous NSCLC. PARAMOUNT was a multicenter, randomized, double-blind, placebo-controlled trial in patients with advanced nonsquamous NSCLC. Results In EA patients with nonsquamous NSCLC, the median progression-free survival (PFS) for pemetrexed continuation maintenance therapy was 4.04 months (95% confidence interval [CI], 3.22 to 5.29 months) in study S110 and 3.9 months (95% CI, 3.2 to 5.2 months) in study JMII. The median PFS for pemetrexed continuation maintenance therapy in PARAMOUNT was 4.1 months (95% CI, 3.2 to 4.6 months). Pemetrexed continuation maintenance therapy in EA patients in studies S110 and JMII did not lead to any unexpected safety events, and was consistent with PARAMOUNT’s safety profile. Conclusion The efficacy and safety data in the EA trials were similar to those in PARAMOUNT despite differences in patient populations and study designs. These data represent consistent evidence for pemetrexed continuation maintenance therapy in EA patients with advanced nonsquamous NSCLC. PMID:25410761

Medulloblastoma (MB) is the most common malignant pediatric brain tumor. Despite great improvements in the therapeutic regimen, relapse and leptomeningeal dissemination still pose great challenges to the long-term survival of MB patients. Developing more effective strategies has become extremely urgent. In recent years, a number of malignancies, including MB, have been found to contain a subpopulation of cancer cells known as cancer stem cells (CSCs), or tumor initiating/propagating cells. The CSCs are thought to be largely responsible for tumor initiation, maintenance, dissemination, and relapse; therefore, their pivotal roles have revealed them to be promising targets in MB therapy. Our growing understanding of the major medulloblastoma molecular subgroups and the derivation of some of these groups from specific stem or progenitor cells adds additional layers to the CSC knowledge base. Herein we review the current knowledge of MB stem cells, highlight the molecular mechanisms relating to MB relapse and leptomeningeal dissemination, and incorporate these with the need to develop more effective and accurate therapies for MB patients. © 2016 The Authors.

Vietnam has a concentrated HIV epidemic with injection drug use being the dominant mode of HIV transmission. Vietnam has rapidly expanded antiretroviral therapy (ART) and methadone maintenance therapy (MMT). This study aims to analyze ART uptake and retention among male clients receiving MMT in Vietnam in the early phase of the MMT program. The male clients (age ≥18) who were newly enrolled in care or started ART at two HIV clinics in Hanoi (2009 to 2011) and three HIV clinics in Can Tho (2010 to 2012) were included for the analysis. The CD4 lymphocyte count at HIV care enrollment and ART initiation and retention on ART were retrospectively analyzed. The values of those receiving MMT were compared with the values of two groups: those in whom injection drug use (IDU) status was documented, but were not receiving MMT, and all male clients not receiving MMT. To analyze retention, survival analysis with log rank test and Cox proportional hazard model was used. During the study period, 663 adult men were newly enrolled in HIV care (237 had IDU status documented) and 456 initiated ART (167 had IDU status documented). Among those who initiated ART, 28 were receiving MMT. At care enrolment, those receiving MMT had a median CD4 count of 230 (IQR 57-308) cells/mm 3 , while men self-reporting IDU and not receiving MMT and all men not receiving MMT had a median CD4 count of 158 (IQR 50-370) cells/mm 3 and 143 (IQR 35-366) cells/mm 3 , respectively. At ART initiation, men receiving MMT had significantly higher CD4 count with median at 203 (IQR 64-290) cells/mm 3 than men self-reporting IDU and not receiving MMT (80, IQR 40-220, cells/mm 3 , p = 0.038) and all men not receiving MMT (76, IQR 20-199, cells/mm 3 , p = 0.009). Those receiving MMT had a significantly higher retention rate than those self-reporting IDU but not receiving MMT (hazard ratio = 0.18, p = 0.019) and men not receiving MMT (hazard ratio = 0.20, p = 0.041). Our analysis suggests that men receiving MMT in Vietnam are achieving relatively early uptake and high retention rates on ART. The findings support potential benefits of integrating MMT and ART services in Vietnam.

Single-inhaler combination therapy for maintenance and relief of asthma: a new strategy in disease management.

PubMed

Peters, Matthew

2009-01-01

When an adequate standard of asthma control is not achieved with maintenance treatment of inhaled corticosteroids, the addition of a long-acting beta(2)-adrenergic receptor agonist (LABA) bronchodilator is recommended. Using a combination product, salmeterol/fluticasone propionate (Seretide or Advair) or budesonide/formoterol (Symbicort) is preferred for convenience and avoids any risk that LABA might be used as monotherapy. As formoterol has a rapid onset of bronchodilator effect, the budesonide/formoterol combination can be used for both the maintenance and reliever components of asthma treatment (Symbicort SMART) and this is endorsed as an effective treatment by the Global Initiative for Asthma. The efficacy of this approach has been evaluated in a series of well conducted, controlled studies. Current control of asthma symptoms is improved or achieved with reduced total dose administration with Symbicort SMART compared with any reasonable alternate option. In every study, the risk of severe exacerbations was lower with Symbicort SMART than comparator treatment. Patients who benefit to the greatest extent are those with evidence of more severe asthma and greater exacerbation risk. When initiated in suitable patients in conjunction with appropriate education, Symbicort SMART is dominant in pharmacoeconomic terms. Symbicort SMART delivers improved asthma outcomes with lower treatment and social costs than any alternative.

Alternatives to lithium and divalproex in the maintenance treatment of bipolar disorder.

2003-06-01

The role of lithium carbonate in the maintenance treatment of bipolar disorder is well established. Unfortunately, many patients fail to respond adequately to this agent or are unable to tolerate its adverse effects. Divalproex has become a commonly used alternative to lithium, but it also is ineffective or poorly tolerated in many patients. This article attempts to review the available data on maintenance therapy in bipolar disorder with a variety of anticonvulsants and antipsychotics (both conventional and novel), with reference to relevant studies in acute mania and bipolar depression as well. Evidence on maintenance therapy and relevant acute-phase data were collected using MEDLINE database searches. Data on maintenance therapy with agents other than lithium and divalproex are sparse, and often derived from open, uncontrolled studies. Implications and flaws of available data are discussed. Other than lithium, there are few robust double-blind data to support the use of a variety of agents in the maintenance phase. However, uncontrolled data suggest that a number of agents merit further study.

Treat-to-target recommendations have identified 'remission' as a target in systemic lupus erythematosus (SLE), but recognise that there is no universally accepted definition for this. Therefore, we initiated a process to achieve consensus on potential definitions for remission in SLE. An international task force of 60 specialists and patient representatives participated in preparatory exercises, a face-to-face meeting and follow-up electronic voting. The level for agreement was set at 90%. The task force agreed on eight key statements regarding remission in SLE and three principles to guide the further development of remission definitions:1. Definitions of remission will be worded as follows: remission in SLE is a durable state characterised by …………………. (reference to symptoms, signs, routine labs).2. For defining remission, a validated index must be used, for example, clinical systemic lupus erythematosus disease activity index (SLEDAI)=0, British Isles lupus assessment group (BILAG) 2004 D/E only, clinical European consensus lupus outcome measure (ECLAM)=0; with routine laboratory assessments included, and supplemented with physician's global assessment.3. Distinction is made between remission off and on therapy: remission off therapy requires the patient to be on no other treatment for SLE than maintenance antimalarials; and remission on therapy allows patients to be on stable maintenance antimalarials, low-dose corticosteroids (prednisone ≤5 mg/day), maintenance immunosuppressives and/or maintenance biologics.The task force also agreed that the most appropriate outcomes (dependent variables) for testing the prognostic value (construct validity) of potential remission definitions are: death, damage, flares and measures of health-related quality of life. The work of this international task force provides a framework for testing different definitions of remission against long-term outcomes. Published by the BMJ Publishing Group Limited.

2013-05-01

This prospective study evaluates immediately placed and immediately provisionalized implants in the esthetic zone. All implants were TiO2-blasted, fluoride-modified, grade 4 titanium, with a coronal microthread design. Bone grafting and guided bone regeneration (GBR) was performed at all sites, and screw-retained temporary restorations were delivered on the day of surgery. All of the provisional crown(s) were out of occlusal function and remained in place for at least 8 weeks prior to initiation of definitive restorative therapy. Bone maintenance (BM) was considered successful if radiographs demonstrated proximal bone levels even or coronal to the implant platform. Of the 29 implants placed, 25 (86 percent) achieved bone maintenance at least 12 months post-loading with the final restorations. This study was considered successful, with 100 percent implant survival after at least 1 year loading of the final restoration, and 100 percent of patients were satisfied with the esthetics of their implant treatment.

Limited improvement in long term survival of lung cancer patients has been achieved by conventional chemotherapy or targeted therapy. To explore the potentials of tumor initiating cells (TIC)-directed therapy, it is essential to identify the cell targets and understand their maintenance mechanisms. We have analyzed the performance of ALDH/CD44 co-expression as TIC markers and treatment targets of lung cancer using well-validated in vitro and in vivo analyses in multiple established and patient-derived lung cancer cells. The ALDH(hi)CD44(hi) subset showed the highest enhancement of stem cell phenotypic properties compared to ALDH(hi)CD44(lo), ALDH(lo)CD44(hi), ALDH(lo)CD44(lo) cells and unsorted controls. They showed higher invasion capacities, pluripotency genes and epithelial-mesenchymal transition transcription factors expression, lower intercellular adhesion protein expression and higher G2/M phase cell cycle fraction. In immunosuppressed mice, the ALDH(hi)CD44(hi)xenografts showed the highest tumor induction frequency, serial transplantability, shortest latency, largest volume and highest growth rates. Inhibition of sonic Hedgehog and Notch developmental pathways reduced ALDH+CD44+ compartment. Chemotherapy and targeted therapy resulted in higher AALDH(hi)CD44(hi) subset viability and ALDH(lo)CD44(lo) subset apoptosis fraction. ALDH inhibition and CD44 knockdown led to reduced stemness gene expression and sensitization to drug treatment. In accordance, clinical lung cancers containing a higher abundance of ALDH and CD44-coexpressing cells was associated with lower recurrence-free survival. Together, results suggested theALDH(hi)CD44(hi)compartment was the cellular mediator of tumorigenicity and drug resistance. Further investigation of the regulatory mechanisms underlying ALDH(hi)CD44(hi)TIC maintenance would be beneficial for the development of long term lung cancer control.

Pediatric Fluid and Electrolyte Therapy

PubMed Central

Meyers, Rachel S.

2009-01-01

Managing fluids and electrolytes in children is an important skill for pharmacists, who can play an important role in monitoring therapy. Fluid therapy is divided into maintenance, deficit, and replacement requirements. The Holliday-Segar equation remains the standard method for calculating maintenance fluid requirements. Accounting for deficits when determining the fluid infusion rate is an important factor in treating dehydrated patients; deficit fluid is generally administered over the first 24 hours of hospitalization. Maintenance electrolyte requirements must be taken into account, with particular attention paid to sodium requirements, as recent evidence suggests that sodium needs in hospitalized children are higher than originally thought. Fluid therapy can also have an impact on drug therapy. Hydration status can affect the dose needed to achieve therapeutic concentrations, and dehydrated patients may be at risk for toxicity if standard doses of drugs with high volumes of distribution are used. Monitoring fluid and electrolyte therapy is an important role of the pediatric pharmacist. PMID:23055905

Periodontal disease is a chronic disease that is perceived by many patients to be nonthreatening. Periodontal therapy has been shown to be less effective if a regular periodontal maintenance schedule is not followed after completion of active therapy. Periodontal maintenance is an integral part of successful periodontal therapy.

Through inhibition of purine de novo synthesis and enhancement of 6-mercaptopurine (6MP) bioavailability high-dose methotrexate (HDM) may increase the incorporation into DNA of 6-thioguanine nucleotides (6TGN), the cytoxic metabolites of 6MP. Thus, coadministration of 6MP could increase myelotoxicity following HDM. Twenty-one children with standard risk (SR) and 25 with intermediate risk (IR) acute lymphoblastic leukemia (ALL) were studied. During consolidation therapy they received either three courses of HDM at 2 week intervals without concurrent oral 6MP (SR-ALL) or four courses of HDM given at 2 week intervals with 25 mg/m2 of oral 6MP daily (IR-ALL). During the first year of maintenance with oral 6MP (75 mg/m2/day) and oral MTX (20 mg/m2/week) they all received five courses of HDM at 8 week intervals. In all cases, HDM consisted of 5,000 mg of MTX/m2 given over 24 h with intraspinal MTX and leucovorin rescue. Erythrocyte levels of 6TGN (E-6TGN) and methotrexate (E-MTX) were, on average, measured every second week during maintenance therapy. When SR consolidation (6MP: 0 mg), IR consolidation (6MP: 25 mg/m2), and SR/IR maintenance therapy (6MP: 75 mg/m2) were compared, white cell and absolute neutrophil count (ANC) nadir, lymphocyte count nadir, thrombocyte count nadir, and hemoglobin nadir after HDM decreased significantly with increasing doses of oral 6MP. Three percent of the HDM courses given without oral 6MP (SR consolidation) were followed by an ANC nadir <0.5 x 10(9)/l compared to 50% of the HDM courses given during SR/IR maintenance therapy. Similarly, only 13% of the HDM courses given as SR-ALL consolidation induced a thrombocyte count nadir <100 x 10(9)/l compared to 58% of the HDM courses given during maintenance therapy. The best-fit model to predict the ANC nadir following HDM during maintenance therapy included the dose of 6MP prior to HDM (beta = -0.017, P= 0.001), the average ANC level during maintenance therapy (beta = 0.82, P = 0.004), and E-6TGN (beta = -0.0029, P= 0.02). The best-fit model to predict the thrombocyte nadir following HDM during maintenance therapy included only mPLATE (beta = 0.0057, P = 0.046). In conclusion, the study indicates that reductions of the dose of concurrently given oral 6MP could be one way of reducing the risk of significant myelotoxicity following HDM during maintenance therapy of childhood ALL.

A 55-year-old woman underwent laparoscopic anterior resection and D2 lymph node dissection for recto-sigmoid colon cancer in November 2014, which was diagnosed as T3N1M1(H3, PUL2), stage IV , for the purpose of preserving the ileus. FOLFOX therapy with panitumumab(Pmab)was started in January 2015.A t the end of 11 courses, pulmonary metastasis changed to CR, and liver metastasis was down-graded to H2 on the CT.Because of the risk of hepatic dysfunction with advanced fatty liver due to chemotherapy and extrahepatic lesions, we chose radiofrequency ablation(RFA)therapy for liver metastasis.Pmab combined FOLFIRI therapy was administered, and maintenance therapy was initiated.This patient is alive 2 years and 7 months after surgery and 10 months after RFA without relapse.It is suggested that RFA therapy for liver metastasis of colon cancer with pulmonary metastasis combined with chemotherapy could be an effective treatment strategy.

Intravenous bisphosphonate therapy is the first-line treatment in moderate-to-severe osteogenesis imperfecta (OI), but there are varied treatment protocols with little data on long-term efficacy. This study evaluates the clinical outcomes when transitioning from active bisphosphonate treatment to maintenance therapy. A retrospective review was conducted on 17 patients before treatment, following active treatment (zoledronate 0.05 mg/kg 6-monthly or pamidronate 6-9 mg/kg/year) and after establishment on maintenance treatment for more than 2 years (zoledronate 0.025 mg/kg 6-monthly or pamidronate <4 mg/kg/year). There was a significant reduction in mean fracture rate from 1.5 ± 1.1 fractures/year at baseline to 0.7 ± 0.7 fractures/year on active treatment. Z-scores for lumbar spine bone mineral density, bone mineral content, volumetric bone mineral density and bone mineral content for lean tissue mass increased during active treatment. These improvements were maintained during the period of maintenance treatment. Vertebral height improved in fractured thoracic vertebrae from pre-treatment to active therapy and improved further during maintenance treatment. Metacarpal cortical thickness and relative cortical area also increased over the treatment periods. Maintenance intravenous bisphosphonate therapy preserved the beneficial effects of active treatment at the doses stated above. Further studies are required to determine the optimal bisphosphonate treatment regimen in the management of children with OI. © 2015 S. Karger AG, Basel.

Infliximab (IFX) therapy intensification in ulcerative colitis (UC) is more common than established in pivotal studies. To establish the frequency and form of intensification for UC in clinical practice, as well as predictors, and to compare outcomes between intensified and non-intensified treatment. A retrospective study of 10 hospitals and 144 patients with response to infliximab (IFX) induction. Predictive variables for intensification were analyzed using a Cox regression analysis. Outcome, loss of response to IFX, and colectomy were compared between intensified and non-intensified therapy. Follow-up time from induction to data collection: 38 months [interquartile range (IQR), 20-62]. Time on IFX therapy: 24 months (IQR, 10-44). In all, 37% of patients required intensification. Interval was shortened for 36 patients, dose was increased for 7, and 10 subjects received both. Concurrent thiopurine immunosuppressants (IMM) and IFX initiation was an independent predictor of intensification [Hazard ratio, 0.034; p, 0.006; CI, 0.003-0.371]. In patients on intensified therapy IFX discontinuation for loss of response (30.4% vs. 10.2%; p, 0.002), steroid reintroduction (35% vs. 18%; p, 0.018), and colectomy (22% vs. 6.4%; p, 0.011) were more common. Of patients on intensification, 17% returned to receiving 5 mg/kg every 8 weeks. Intensification is common and occasionally reversible. IMM initiation at the time of induction with IFX predictsnon-intensification. Intensification, while effective, is associated with poorer outcome.

Opioid Analgesics for Chronic Non-Cancer Pain: A Guideline on Opioid Prescribing.

2016-01-01

Over the past decade, the use of opioid analgesics has risen dramatically both in the U.S. and South Dakota. Opioids have been increasingly used to treat chronic non-cancer pain; however, the utilization of opioids for this role has limited and questionable utility. The U.S. has also seen a rise of opioid abuse, addiction, misuse, and overdose. The various pharmacological and non-pharmacological strategies to help physicians manage chronic non-cancer pain and a guideline on appropriate opioid prescribing are presented. Before the decision is made to begin opioid therapy for chronic non-cancer pain, other pharmacological and non-pharmacological therapeutic strategies should be explored. The schema for responsible opioid prescribing can be dived into the following: the initial assessment, initiating opioid therapy, maintenance therapy, and the discontinuation of opioid treatment. These categories are explored, and a general approach to prescribing opioids for chronic non-cancer pain is presented. The Centers for Disease Control and Prevention (CDC) has declared opioid prescription abuse an "epidemic." There are a variety of methods clinicians can utilize to relieve chronic non-cancer pain. If opioid therapy is sought, clinicians should be mindful of the current state of opioid abuse and misuse. This guideline may aid clinicians in appropriate opioid prescribing.

Gastro-oesophageal reflux disease (GORD) is a recurring condition with many patients requiring long-term maintenance therapy. Therefore initial choice of treatment has long-term cost implications. The aim was to compare the costs and effectiveness of treatment of GORD the (unconfirmed by endoscopy) with seven proton pump inhibitors (PPIs: esomeprazole, lansoprazole (capsules and oro-dispersible tablets), omeprazole (generic and branded), pantoprazole and rabeprazole), over one year. A treatment model was developed of 13 interconnected Markov models incorporating acute treatment of symptoms, long-term therapy and subsequent decisions to undertake endoscopy to confirm diagnosis. Patients were allowed to stop treatment or to receive maintenance treatment either continuously or on-demand depending on response to therapy. Long-term dosing schedule (high dose or step-down dose) was based on current market data. Efficacy of treatments was based on clinical trials and follow-up studies, while resource use patterns were determined by a panel of physicians. The model predicts total expected annual costs, number of symptom-free days and quality-adjusted life-years (QALY). Generic omeprazole and rabeprazole dominated (i.e. cost less and resulted in more symptom-free days and higher QALY gains) the other PPIs. Rabeprazole had a favourable cost-effectiveness ratio of 3.42 pounds per symptom-free day and 8308 pounds/quality-adjusted life-year gained when compared with generic omeprazole. Rabeprazole remained cost-effective independent of choice of maintenance treatment (i.e. proportion of patients remaining on continuous treatment versus on-demand treatment). Economic models provide a useful framework to evaluate PPIs in realistic clinical scenarios. Our findings show that rabeprazole is cost-effective for the treatment of GORD.

The use of cetuximab in the treatment of metastatic colorectal cancer is limited by development of resistance. We have investigated in three models of highly epidermal growth factor receptor (EGFR)-dependent colorectal cancer xenografts, the effect of maintenance therapy with different kinase inhibitors alone or in combination with cetuximab, after cytotoxic treatment induction with irinotecan plus cetuximab. SW48, LIM 1215, and GEO colorectal cancer cell lines were engrafted into nude mice and treated for 3 weeks with irinotecan and/or cetuximab. The combined treatment induced a significant reduction of tumor size. A subsequent experiment was performed in all three xenograft models in which after an induction treatment with irinotecan plus cetuximab, mice were randomly assigned to one of the following treatments: control, cetuximab, regorafenib, a selective PIK3CA inhibitor (PIK3CAi), a selective MEK inhibitor (MEKi), and/or the combination of each inhibitor with cetuximab. The cetuximab plus MEKi treatment determined the best antitumor activity with suppression of tumor growth. This effect was prolonged for 13 to 15 weeks after cessation of therapy and was accompanied by prolonged survival. Antitumor activity was accompanied by inhibition of the MAPK and MEK pathways. Moreover, in the cetuximab plus MEKi-treated SW48 xenograft group, KRAS mutations as a mechanism of acquired resistance were detected in 25% of cases compared with 75% KRAS mutations in the MEKi-treated group. A possible strategy to prevent and/or overcome resistance to anti-EGFR inhibitors in metastatic colorectal cancer is a maintenance therapy with cetuximab plus MEKi after an initial treatment with irinotecan plus cetuximab. ©2015 American Association for Cancer Research.

This study constitutes a revision of the guidelines for the treatment of major depressive disorder (MDD) issued by the Korean Medication Algorithm Project for Depressive Disorder (KMAP-DD) 2006. In incorporates changes in the experts׳ consensus that occurred between 2006 and 2012 as well as information regarding newly developed and recently published clinical trials. Using a 44-item questionnaire, an expert consensus was obtained on pharmacological treatment strategies for (1) non-psychotic MDD, (2) psychotic MDD, (3) dysthymia and depression subtypes, (4) continuous and maintenance treatment, and (5) special populations; consensus was also obtained regarding (6) the choice of an antidepressant (AD) in the context of safety and adverse effects, and (7) non-pharmacological biological therapies. AD monotherapy was recommended as the first-line strategy for nonpsychotic depression in adults, children and adolescents, elderly adults, and patients with postpartum depression or premenstrual dysphoric disorder. The combination of AD and atypical antipsychotics (AAP) was recommended for psychotic depression. The duration of the initial AD treatment for psychotic depression depends on the number of depressive episodes. Most experts recommended stopping the initial AD and AAP therapy after a certain period in patients with one or two depressive episodes. However, for those with three or more episodes, maintenance of the initial treatment was recommended for as long as possible. Monotherapy with various selective serotonin reuptake inhibitors (SSRIs) and serotonin and norepinephrine reuptake inhibitors (SNRIs) was recommended for dysthymic disorder and melancholic type MDD. The pharmacological treatment strategy of KMAP-DD 2012 is similar to that of KMAP-DD 2006; however, the preference for the first-line use of AAPs was stronger in 2012 than in 2006.

Therapy discontinuations and toxicities occur because of significant interindividual variations in 6-mercaptopurine (6-MP) and methotrexate (MTX) response during maintenance therapy of childhood acute lymphoblastic leukemia (ALL). 6-MP/MTX intolerance in some of the patients cannot be explained by thiopurine S-methyl transferase (TPMT) gene variants. In this study, we aimed to investigate candidate pharmacogenetic determinants of 6-MP and MTX intolerance in Turkish ALL children. In total, 48 children with ALL who had completed or were receiving maintenance therapy according to Children's Oncology Group (COG) protocols were enrolled. Fifteen single-nucleotide polymorphisms in 8 candidate genes that were related to drug toxicity or had a role in the 6-MP/MTX metabolism (TPMT, ITPA, MTHFR, IMPDH2, PACSIN2, SLCO1B1, ABCC4, and PYGL) were genotyped by competitive allele-specific PCR (KASP). Drug doses during maintenance therapy were modified according to the protocol. The median drug dose intensity was 50% (28% to 92%) for 6-MP and 58% (27% to 99%) for MTX in the first year of maintenance therapy, which were lower than that scheduled in all patients. Among the analyzed polymorphisms, variant alleles in SLCO1B1 rs4149056 and rs11045879 were found to be associated with lower 6-MP/MTX tolerance. SLCO1B1 rs4149056 and rs11045879 polymorphisms may be important genetic markers to individualize 6-MP/MTX doses.

Eumycetoma is a chronic infection of the skin and subcutaneous tissue caused by filamentous fungi, which usually occurs in tropical or subtropical countries. We report a case of an immunocompromised patient presenting with presumed eumycetoma in the United States and his subsequent treatment with voriconazole. The use of voriconazole and liposomal amphotericin B halted the progression and allowed gradual resolution of the infection. The patient will require close monitoring and long-term therapy with voriconazole to obtain a clinical cure. Voriconazole and liposomal amphotericin B are potential initial treatment options, with long-term voriconazole maintenance therapy, for an Aspergillus-induced eumycetoma. © 2014 John Wiley & Sons A/S.

Lung cancer is the most common cancer worldwide with non-small cell lung cancer (NSCLC), including squamous carcinoma, adenocarcinoma and large cell carcinoma, accounting for about 85% of all lung cancer types with most of the patients presenting with advanced disease at the time of diagnosis. In this setting first-line platinum-based chemotherapy for no more than 4-6 cycles are recommended. After these cycles of treatment, non-progressing patients enter in the so called "watch and wait" period in which no further therapy is administered until there is disease progression. In order to improve the advanced NSCLC outcomes, the efficacy of further treatment in the "watch and wait" period was investigated. This is the "maintenance therapy". Recently, the results coming from randomized phase III trials investigating two new agents, pemetrexed and erlotinib, in this setting led to their registration for maintenance therapy. Here, we report and discuss these results. Copyright © 2010 Elsevier Ltd. All rights reserved.

Initial therapy consisted of 5400 rads in seven weeks to the right side of the pelvis and 14 intravenous injections of cyclophosphamide (Cytoxan, CTX) at 500 mg/m/sup 2/; BCNU and Adriamycin maintenance therapy continued for a total of two years. He has now been disease-free for five years. Three months following the completion of the right pelvic radiotherapy (RT), while on intravenous CTX, severe hematuria appeared, which subsided, but at present he has continuous microscopic hematuria, as well as periodic episodes of gross hematuria. Serial cystocopiesmore » initially revealed thickening and hemorrhagic and edematous changes on the right (irradiated) side of the bladder, and recent multiple telangiectatic patches have been demonstrated as a late healing phase. This case demonstrates the additive toxicity to the bladder of CTX and RT, illustrating that the hemorrhagic cystitis can be extremely protracted lasting five years.« less

[Poorly differentiated thyroid carcinomas: new therapeutic considerations].

PubMed

Graf, Hans

2005-10-01

For most differentiated thyroid carcinomas, as papillary and follicular carcinomas, following total thyroidectomy and 131I therapy for thyroid remnant ablation, treatment with thyroid hormones to suppress TSH levels will reduce the growth of any remaining thyroid cancer cells, and thyroid cell-specific radiation therapy will either cure or control the disease. Thyroid carcinomas are considered poorly differentiated when they start to lose such functions as iodine uptake and thyrotropin-dependence for growth and production of thyroid proteins like NIS, thyroglobulin and desiodases. One of the greatest challenges in the management of patients with follicular cell-derived thyroid cancer is the treatment of tumors that progressed despite surgery, (131)I and T4 suppression of TSH. With the better knowledge of the abnormal molecular signaling in thyroid cancer cells, actually known targeted cancer therapies, directed against molecules involved in neoplastic transformation, are being used. As the critical molecular requirements for tumor initiation, maintenance and progression are identified, combination therapies with targeted agents acting on each of them will improve the treatment of poorly differentiated thyroid carcinoma.

Methotrexate/6-mercaptopurine maintenance therapy of childhood acute lymphoblastic leukemia is challenged by treatment-related hepatotoxicity, failure to achieve the myelosuppressive target, and lack of direct parameters for monitoring treatment efficacy or even intensity. Patients with low thiopurine methyltransferase (TPMT) activity have lower levels of hepatotoxic methylated thiopurine metabolites (MeMPs), higher levels of thioguanine nucleotides (TGNs), and reduced relapse rates. Addition of 6-thioguanine to maintenance therapy of a child with ALL and high TPMT activity increased the TGN/MeMP index in erythrocytes 5.5-fold, mimicking the more favorable thiopurine metabolism seen in patients with low TPMT activity.

Advanced chronic kidney disease is associated with elevated risk for cognitive impairment. However, it is not known whether and how cognitive impairment is associated with planning and preparation for end-stage renal disease. Retrospective observational study. 630 adults participating in the CRIC (Chronic Renal Insufficiency Cohort) Study who had cognitive assessments in late-stage CKD, defined as estimated glome-rular filtration rate ≤ 20mL/min/1.73m 2 , and subsequently initiated maintenance dialysis therapy. Predialysis cognitive impairment, defined as a score on the Modified Mini-Mental State Examination lower than previously derived age-based threshold scores. Covariates included age, race/ethnicity, educational attainment, comorbid conditions, and health literacy. Peritoneal dialysis (PD) as first dialysis modality, preemptive permanent access placement, venous catheter avoidance at dialysis therapy initiation, and preemptive wait-listing for a kidney transplant. Multivariable-adjusted logistic regression. Predialysis cognitive impairment was present in 117 (19%) participants. PD was the first dialysis modality among 16% of participants (n=100), 75% had preemptive access placed (n=473), 45% avoided using a venous catheter at dialysis therapy initiation (n=279), and 20% were preemptively wait-listed (n=126). Predialysis cognitive impairment was independently associated with 78% lower odds of PD as the first dialysis modality (adjusted OR [aOR], 0.22; 95% CI, 0.06-0.74; P=0.02) and 42% lower odds of venous catheter avoidance at dialysis therapy initiation (aOR, 0.58; 95% CI, 0.34-0.98; P=0.04). Predialysis cognitive impairment was not independently associated with preemptive permanent access placement or wait-listing. Potential unmeasured confounders; single measure of cognitive function. Predialysis cognitive impairment is associated with a lower likelihood of PD as a first dialysis modality and of venous catheter avoidance at dialysis therapy initiation. Future studies may consider addressing cognitive function when testing strategies to improve patient transitions to dialysis therapy. Copyright © 2018 National Kidney Foundation, Inc.

[Stopping secondary prevention in AIDS patients with inactive CMV retinitis treated with HAART (highly active antiretroviral therapy)].

Best, J; Althaus, C; Kersten, A; Theisen, A; Gantke, B

2000-08-01

Immune recovery of AIDS patients with cytomegalovirus (CMV) retinitis treated and healed by highly active antiretroviral therapy (HAART) is reflected by increased CD4 cell count and decreased virus load. Due to partial reconstitution of the immune status the risk of opportunistic infections decreases, as well as the risk of reactivating inactive CMV retinitis. It may therefore be possible to stop anti-CMV maintenance therapy may after HAART-induced immune recovery. We present six patients (nine eyes) with a follow-up of 9.5 months (range 7-12 months) after cessation of the CMV-specific maintenance therapy (five orally, one intravenously). There was no reactivation of retinal CMV infection during the follow-up period. The virus load (< 50 Eq/ml; a single value of one patient was 2047 Eq/ml) and CD4 cell counts (range 207-454/microliter; mean: 313/microliter) remained stable during the follow-up period, reflecting immune recovery. Our findings confirm the expected low risk of retinal CMV reactivation after immune recovery in AIDS patients receiving HAART without secondary prophylaxis with an anti-CMV maintenance therapy. Regular ophthalmic and medical follow-up is mandatory in these patients. Cessation of maintenance therapy represents a major improvement in quality of live in AIDS patients.

Little is known about rehabilitation for postthoracotomy non-small cell lung cancer (NSCLC) patients. This research uses a perceived self-efficacy-enhancing light-intensity exercise intervention targeting a priority symptom, cancer-related fatigue (CRF), for postthoracotomy NSCLC patients. This article reports on phase II of a 2-phase study. Phase I focused on initiation and tolerance of exercise during the 6 weeks immediately after thoracotomy, whereas phase II addressed maintenance of exercise for an additional 10 weeks including participants initiating and completing chemotherapy and/or radiation therapy. The objective of this study was to investigate the feasibility, acceptability, and preliminary efficacy of an exercise intervention for postthoracotomy NSCLC patients to include those initiating and completing adjuvant therapy. A single-arm design composed of 7 participants postthoracotomy for NSCLC performed light-intensity exercises using an efficacy-enhancing virtual-reality approach using the Nintendo Wii Fit Plus. Despite most participants undergoing chemotherapy and/or radiation therapy, participants adhered to the intervention at a rate of 88% with no adverse events while giving the intervention high acceptability scores on conclusion. Likewise, participants' CRF scores improved from initiation through the conclusion of the intervention with perceived self-efficacy for walking at a light intensity continuously for 60 minutes, improving significantly upon conclusion over presurgery values. Postthoracotomy NSCLC patients maintained exercise for an additional 10 weeks while undergoing adjuvant therapy showing rehabilitation potential because the exercise intervention was feasible, safe, well tolerated, and highly acceptable showing positive changes in CRF self-management. A randomized controlled trial is needed to further investigate these relationships.

Excimer laser therapy and narrowband ultraviolet B therapy for exfoliative cheilitis.

2015-06-01

Exfoliative cheilitis is a condition of unknown etiology characterized by hyperkeratosis and scaling of vermilion epithelium with cyclic desquamation. It remains largely refractory to treatment, including corticosteroid therapy, antibiotics, antifungals, and immunosuppressants. We sought to evaluate the safety and efficacy of excimer laser therapy and narrowband ultraviolet B therapy in female patients with refractory exfoliative cheilitis. We reviewed the medical records of two female patients who had been treated unsuccessfully for exfoliative cheilitis. We implemented excimer laser therapy, followed by hand-held narrowband UVB treatments for maintenance therapy, and followed them for clinical improvement and adverse effects. Both patients experienced significant clinical improvement with minimal adverse effects with excimer laser therapy 600-700 mJ/cm 2 twice weekly for several months. The most common adverse effects were bleeding and burning, which occurred at higher doses. The hand-held narrowband UVB unit was also an effective maintenance tool. Limitations include small sample size and lack of standardization of starting dose and dose increments. Excimer laser therapy is a well-tolerated and effective treatment for refractory exfoliative cheilitis with twice weekly laser treatments of up to 700 mJ/cm 2 . Transitioning to the hand-held narrowband UVB device was also an effective maintenance strategy.

After successful inhibition of threatened preterm labour women are at high risk of recurrent preterm labour. Terbutaline pump maintenance therapy has been used to reduce adverse neonatal outcomes. This review replaces an earlier Cochrane review, published in 2002, which is no longer being updated by the team. To determine the effectiveness of terbutaline pump maintenance therapy after threatened preterm labour in reducing adverse neonatal outcomes. We searched the Cochrane Pregnancy and Childbirth Group's Trials Register (31 January 2014) and reference lists of retrieved studies. Randomised controlled trials comparing terbutaline pump therapy with alternative therapy, placebo, or no therapy after arrest of threatened preterm labour. Two review authors independently assessed the studies for inclusion and then extracted data as eligible for inclusion in qualitative and quantitative synthesis (meta-analysis). Four studies were included with a total of 234 women randomised. The overall methodological quality of the included studies was mixed; two studies provided very little information on study methods, there was high sample attrition in one study and in three studies the risk of performance bias was high. We found no strong evidence that terbutaline maintenance therapy offered any advantages over saline placebo or oral terbutaline maintenance therapy in reducing adverse neonatal outcomes by prolonging pregnancy among women with arrested preterm labour. The mean difference (MD) for gestational age at birth was -0.14 weeks (95% confidence interval (CI) -1.66 to 1.38) for terbutaline pump therapy compared with saline placebo pump for two trials combined. One trial reported a risk ratio (RR) of 1.17 (95% CI 0.79 to 1.73) for preterm birth (less than 37 completed weeks) and a RR of 0.97 (95% CI 0.51 to 1.84) of very preterm birth (less than 34 completed weeks) for terbutaline pump compared with saline placebo pump. We found no evidence that terbutaline pump therapy was associated with statistically significant reductions in infant respiratory distress syndrome, or neonatal intensive care unit admission compared with placebo. Compared with oral terbutaline, we found no evidence that pump therapy increased the rate of therapy continuation, or reduced the rate of infant complications or maternal hospital re-admissions. One study suggested that pump therapy resulted in significantly increased weekly cost/woman, $580 versus $12.50 (P < 0.01). No data were reported on long-term infant outcomes. We found no evidence that terbutaline pump maintenance therapy decreased adverse neonatal outcomes. Taken together with the lack of evidence of benefit, its substantial expense and the lack of information on the safety of the therapy do not support its use in the management of arrested preterm labour. Future use should only be in the context of well-conducted, adequately powered randomised controlled trials.

Vedolizumab, the first drug in the class of anti-integrin molecules, is newly approved for ulcerative colitis and Crohn's disease and can be prescribed in Germany since mid-2014. By a specific receptor binding a relatively gut-selective mode of action was achieved without the known side effects of the systemic immunosuppression of the anti-TNF-alpha antibodies. According to the present data the safety profile of Vedolizumab appears to be more favorable than that of the anti-TNF- alpha therapy. Vedolizumab is suitable for induction therapy in patients with ulcerative colitis and Crohn's disease, however the kinetic of response compared with the anti-TNF-alpha antibodies seems to be slower. For maintenance therapy the Vedolizumab data show a deep and sustained remission in patients initially responding to induction therapy with a lower loss of efficacy in the long-term treatment known from the anti-TNF-alpha therapy. On the basis of currently available data the efficacy of Vedolizumab in ulcerative colitis appears to be slightly better than in Crohn's disease. © Georg Thieme Verlag KG Stuttgart · New York.

Background. Recommended human immunodeficiency virus (HIV) treatment regimens in the United States contain 3 antiretroviral agents, costing >$30 000/person/year. Pilot studies are evaluating the efficacy of dual therapy with dolutegravir (DTG) and lamivudine (3TC). We examined the potential cost-effectiveness and budget impact of DTG + 3TC regimens in the United States. Methods. Using a mathematical model, we projected the clinical and economic outcomes of antiretroviral therapy (ART)–naive patients under 4 strategies: (1) no ART (for modeling comparison); (2) 2-drug: initial regimen of DTG + 3TC; (3) induction-maintenance: 48-week induction regimen of 3 drugs (DTG/abacavir [ABC]/3TC), followed by DTG + 3TC maintenance if virologically suppressed; and (4) standard of care: 3-drug regimen of DTG/ABC/3TC. Strategy-dependent model inputs, varied widely in sensitivity analyses, included 48-week virologic suppression (88%–93%), subsequent virologic failure (0.1%–0.6%/month), and Medicaid-discounted ART costs ($15 200–$39 600/year). A strategy was considered cost-effective if its incremental cost-effectiveness ratio (ICER) was <$100 000/quality-adjusted life-year (QALY). Results. The 3 ART strategies had the same 5-year survival rates (90%). The ICER was $22 500/QALY for induction-maintenance and >$500 000/QALY for standard of care. Two-drug was the preferred strategy only when DTG + 3TC 48-week virologic suppression rate exceeded 90%. With 50% uptake of either induction-maintenance or 2-drug for ART-naive patients, cost savings totaled $550 million and $800 million, respectively, within 5 years; savings reached >$3 billion if 25% of currently suppressed patients were switched to DTG + 3TC maintenance. Conclusions. Should DTG + 3TC demonstrate high rates of virologic suppression, this regimen will be cost-effective and would save >$500 million in ART costs in the United States over 5 years.

DKK1 mediated inhibition of Wnt signaling in postnatal mice leads to loss of TEC progenitors and thymic degeneration.

Thymic epithelial cell (TEC) microenvironments are essential for the recruitment of T cell precursors from the bone marrow, as well as the subsequent expansion and selection of thymocytes resulting in a mature self-tolerant T cell repertoire. The molecular mechanisms, which control both the initial development and subsequent maintenance of these critical microenvironments, are poorly defined. Wnt signaling has been shown to be important to the development of several epithelial tissues and organs. Regulation of Wnt signaling has also been shown to impact both early thymocyte and thymic epithelial development. However, early blocks in thymic organogenesis or death of the mice have prevented analysis of a role of canonical Wnt signaling in the maintenance of TECs in the postnatal thymus. Here we demonstrate that tetracycline-regulated expression of the canonical Wnt inhibitor DKK1 in TECs localized in both the cortex and medulla of adult mice, results in rapid thymic degeneration characterized by a loss of DeltaNP63(+) Foxn1(+) and Aire(+) TECs, loss of K5K8DP TECs thought to represent or contain an immature TEC progenitor, decreased TEC proliferation and the development of cystic structures, similar to an aged thymus. Removal of DKK1 from DKK1-involuted mice results in full recovery, suggesting that canonical Wnt signaling is required for the differentiation or proliferation of TEC populations needed for maintenance of properly organized adult thymic epithelial microenvironments. Taken together, the results of this study demonstrate that canonical Wnt signaling within TECs is required for the maintenance of epithelial microenvironments in the postnatal thymus, possibly through effects on TEC progenitor/stem cell populations. Downstream targets of Wnt signaling, which are responsible for maintenance of these TEC progenitors may provide useful targets for therapies aimed at counteracting age associated thymic involution or the premature thymic degeneration associated with cancer therapy and bone marrow transplants.

Whether vitamin D reduces clinically important exacerbations of childhood asthma remains uncertain. We compared rapid to maintenance vitamin D repletion analyzed by baseline vitamin D level. Children presenting to the ED with moderate-to-severe asthma exacerbations and vitamin D levels ≤ 25 ng/mL underwent masked randomization, and then open dosing to either IM+oral (the latter daily) therapy or daily oral-only therapy, and were followed for 12 months. The primary outcome was patient-initiated unplanned visits for asthma exacerbations, examined two ways: cumulative proportions with an exacerbation, and average exacerbation frequency. As this was a nutrient study, we analyzed treatment groups by quartile of baseline vitamin D level, collecting repeat levels and clinical observations at 3, 6, 9, and 12 months after enrollment. One hundred and sixteen patients in the IM+oral cohort vs 115 in the oral-only cohort had similar mean (SD) baseline levels: 15.1 (5.4) vs 15.8 (5.2) ng/mL (range, 3-25 ng/mL). There was no difference in the primary outcome over the entire 12-month observation period. However, rapid IM+oral supplementation significantly reduced unplanned visits for asthma exacerbations for children with baseline levels of 3 to 11 ng/mL during the initial 3 months: the relative exacerbation rate for the IM+oral cohort compared with the oral-only cohort at 3 months was 0.48 (95% CI, 0.28-0.89; P = .008); average exacerbation frequency per child analysis, relative rate 0.36 (95% CI, 0.13-0.87; P = .017). Otherwise, there were no significant differences between groups. Rapid compared to maintenance vitamin D supplementation for children with the lowest levels resulted in short- but not long-term reduction in asthma exacerbations.

Mechanisms of Weight Regain following Weight Loss.

2013-01-01

Obesity is a world-wide pandemic and its incidence is on the rise along with associated comorbidities. Currently, there are few effective therapies to combat obesity. The use of lifestyle modification therapy, namely, improvements in diet and exercise, is preferable over bariatric surgery or pharmacotherapy due to surgical risks and issues with drug efficacy and safety. Although they are initially successful in producing weight loss, such lifestyle intervention strategies are generally unsuccessful in achieving long-term weight maintenance, with the vast majority of obese patients regaining their lost weight during followup. Recently, various compensatory mechanisms have been elucidated by which the body may oppose new weight loss, and this compensation may result in weight regain back to the obese baseline. The present review summarizes the available evidence on these compensatory mechanisms, with a focus on weight loss-induced changes in energy expenditure, neuroendocrine pathways, nutrient metabolism, and gut physiology. These findings have added a major focus to the field of antiobesity research. In addition to investigating pathways that induce weight loss, the present work also focuses on pathways that may instead prevent weight regain. Such strategies will be necessary for improving long-term weight loss maintenance and outcomes for patients who struggle with obesity.

Current approaches to the management of new-onset ulcerative colitis

PubMed Central

Marchioni Beery, Renée; Kane, Sunanda

Ulcerative colitis (UC) is an idiopathic, inflammatory gastrointestinal disease of the colon. As a chronic condition, UC follows a relapsing and remitting course with medical maintenance during periods of quiescent disease and appropriate escalation of therapy during times of flare. Initial treatment strategies must not only take into account current clinical presentation (with specific regard for extent and severity of disease activity) but must also take into consideration treatment options for the long-term. The following review offers an approach to new-onset UC with a focus on early treatment strategies. An introduction to the disease entity is provided along with an approach to initial diagnosis. Stratification of patients based on clinical parameters, disease extent, and severity of illness is paramount to determining course of therapy. Frequent assessments are required to determine clinical response, and treatment intensification may be warranted if expected improvement goals are not appropriately reached. Mild-to- moderate UC can be managed with aminosalicylates, mesalamine, and topical corticosteroids with oral corticosteroids reserved for unresponsive cases. Moderate-to-severe UC generally requires oral or intravenous corticosteroids in the short-term with consideration of long-term management options such as biologic agents (as initial therapy or in transition from steroids) or thiopurines (as bridging therapy). Patients with severe or fulminant UC who are recalcitrant to medical therapy or who develop disease complications (such as toxic megacolon) should be considered for colectomy. Early surgical referral in severe or refractory UC is crucial, and colectomy may be a life-saving procedure. The authors provide a comprehensive evidence-based approach to current treatment options for new-onset UC with discussion of long-term therapeutic efficacy and safety, patient-centered perspectives including quality of life and medication compliance, and future directions in related inflammatory bowel disease care.

To establish a baseline for care and overall survival (OS) based upon contemporary first-line treatments prescribed in the era before the introduction of immune checkpoint inhibitors, for people with metastatic non-small cell lung cancer (NSCLC) without common actionable mutations. Using a nationally representative electronic health record data from the Flatiron dataset which included 162 practices from different regions in US, we identified patients (≥18 years old) newly diagnosed with stage IV NSCLC initiating first-line anticancer therapy (November 2012- January 2015, with follow-up through July 2015). Patients with documented epidermal growth factor receptor (EGFR) or anaplastic lymphoma kinase (ALK) translocation were excluded. Anti-cancer drug therapy and overall survival were described overall, and by histology. A total of 2,014 patients with stage IV NSCLC without known EGFR or ALK genomic tumor aberrations initiated systemic anticancer therapy, 22% with squamous and 78% with nonsquamous histology. Their mean (SD) age was 67 (10) years, 55% were male, and 87% had a smoking history. In nonsquamous NSCLC, carboplatin plus pemetrexed either without (25.7%) or with bevacizumab (16%) were the most common regimens; 26.6% of nonsquamous patients receiving induction therapy also received continuation maintenance therapy. In squamous NSCLC, carboplatin plus paclitaxel (37.6%) or nab-paclitaxel (21.1%) were the most commonly used regimens. Overall median OS was 9.7 months (95% CI: 9.1, 10.3), 8.5 months (95% CI: 7.4, 10.0) for squamous, and 10.0 months (95% CI: 9.4, 10.8) for nonsquamous NSCLC. The results provide context for evaluating the effect of shifting treatment patterns of NSCLC treatments on patient outcomes, and for community oncology benchmarking initiatives.

The high levels of healthcare worker shortage is recognised as a severe impediment to increasing patients' access to antiretroviral therapy. This is particularly of concern where the burden of disease is greatest and the access to trained doctors is limited.This review aims to better inform HIV care programmes that are currently underway, and those planned, by assessing if task-shifting care from doctors to non-doctors provides both high quality and safe care for all patients requiring antiretroviral treatment. To evaluate the quality of initiation and maintenance of HIV/AIDS care in models that task shift care from doctors to non-doctors. We conducted a comprehensive search to identify all relevant studies regardless of language or publication status (published, unpublished, in press, and in progress) from 1 January 1996 to 28 March 2014, with major HIV/AIDS conferences searched 23 May 2014. We had also contacted relevant organizations and researchers. Key words included MeSH terms and free-text terms relevant to 'task shifting', 'skill mix', 'integration of tasks', 'service delivery' and 'health services accessibility'. We included controlled trials (randomised or non-randomised), controlled-before and after studies, and cohort studies (prospective or retrospective) comparing doctor-led antiretroviral therapy delivery to delivery that included another cadre of health worker other than a doctor, for initiating treatment, continuing treatment, or both, in HIV infected patients. Two authors independently screened titles, abstracts and descriptor terms of the results of the electronic search and applied our eligibility criteria using a standardized eligibility form to full texts of potentially eligible or uncertain abstracts. Two reviewers independently extracted data on standardized data extraction forms. Where possible, data were pooled using random effects meta-analysis. We assessed evidence quality with GRADE methodology. Ten studies met our inclusion criteria, all of which were conducted in Africa. Of these four were randomised controlled trials while the remaining six were cohort studies.From the trial data, when nurses initiated and provided follow-up HIV therapy, there was high quality evidence of no difference in death at one year, unadjusted risk ratio was 0.96 (95% CI 0.82 to 1.12), one trial, cluster adjusted n = 2770. There was moderate quality evidence of lower rates of losses to follow-up at one year, relative risk of 0.73 (95% CI 0.55 to 0.97). From the cohort data, there was low quality evidence that there may be an increased risk of death in the task shifting group, relative risk 1.23 (95% CI 1.14 to 1.33, two cohorts, n = 39 160) and very low quality data reporting no difference in patients lost to follow-up between groups, relative risk 0.30 (95% CI 0.05 to 1.94).From the trial data, when doctors initiated therapy and nurses provided follow-up, there was moderate quality evidence that there is probably no difference in death compared with doctor-led care at one year, relative risk of 0.89 (95% CI 0.59 to 1.32), two trials, cluster adjusted n = 4332. There was moderate quality evidence that there is probably no difference in the numbers of patients lost to follow-up at one year, relative risk 1.27 (95% CI 0.92 to 1.77), P = 0.15. From the cohort data, there is very low quality data that death at one year may be lower in the task shifting group, relative risk 0.19 (95% CI 0.05 to 0.78), one cohort, n = 2772, and very low quality evidence that loss to follow-up was reduced, relative risk 0.34 (95% CI 0.18 to 0.66).From the trial data, for maintenance therapy delivered in the community there was moderate quality evidence that there is probably no difference in mortality when doctors deliver care in the hospital or specially trained field workers provide home-based maintenance care and antiretroviral therapy at one year, relative risk 1.0 (95% CI 0.62 to 1.62), 1 trial, cluster adjusted n = 559. There is moderate quality evidence from this trial that losses to follow-up are probably no different at one year, relative risk 0.52 (0.12 to 2.3), P = 0.39. The cohort studies did not report on one year follow-up for these outcomes.Across the studies that reported on virological and immunological outcomes, there was no clear evidence of difference whether a doctor or nurse or clinical officer delivered therapy. Three studies report on costs to patients, indicating a reduction in travel costs to treatment facilities where task shifting was occurring closer to patients homes. There is conflicting evidence regarding the relative cost to the health system, as implementation of the strategy may increase costs. The two studies reporting the patient and staff perceptions of the quality of care, report good acceptability of the service by patients, and general acceptance by doctors of the shifting of roles. One trial reported on the time to initiation of antiretroviral therapy, finding no clear evidence of a difference between groups. The same trial reports on new diagnosis of tuberculosis which favours nurse initiation of HIV care for increasing the numbers of diagnoses of tuberculosis made. Our review found moderate quality evidence that shifting responsibility from doctors to adequately trained and supported nurses or community health workers for managing HIV patients probably does not decrease the quality of care and, in the case of nurse initiated care, may decrease the numbers of patients lost to follow-up.

A clinical pharmacy service for managing the treatment of coronary artery disease in a health maintenance organization is described. Despite the proven benefits of aggressive risk factor modification for patients with coronary artery disease (CAD), there remains a treatment gap between consensus- and evidence-based recommendations and their application in patient care. In 1998, Kaiser Permanente of Colorado developed the Clinical Pharmacy Cardiac Risk Service (CPCRS) to focus on the long-term management of patients with CAD to improve clinical outcomes. The primary goals of the CPCRS are to increase the number of CAD patients on lipid-lowering therapy, manage medications shown to decrease the risk of future CAD-related events, assist in the monitoring and control of other diseases that increase cardiovascular risk, provide patient education and recommendations for nonpharmacologic therapy, and act as a CAD information resource for physicians and other health care providers. Using an electronic medical record and tracking database, the service works in close collaboration with primary care physicians, cardiologists, cardiac rehabilitation nurses, and other health care providers to reduce cardiac risk in the CAD population. Particular attention is given to dyslipidemia, blood pressure, diabetes mellitus, and tobacco cessation. Treatment with evidence-based regimens is initiated and adjusted as necessary. Over 11,000 patients are currently being followed by the CPCRS. A clinical pharmacy service in a large health maintenance organization provides cardiac risk reduction for patients with CAD and helps close treatment gaps that may exist for these patients.

To evaluate the planned implementation of group based Cognitive Remediation therapy (CR) and Social Cognitive Interaction Training (SCIT) into routine psychosis care in a mental health service in Australia. The study was conducted over 3 years in a mental health service in a metropolitan city in Australia. Participants were 22 program facilitators and 128 patients attending the programs. Implementation outcomes were assessed using administrative data, staff surveys and program audits. There was fidelity to the particular therapies at a program level. Programs were assessed as being feasible within the study setting with each hospital district developing a capacity to run CR and SCIT. The establishment of new programs improved the reach, but waiting lists indicate a need to expand capacity. There was a relatively high dropout and several factors impacted on completion of the programs - notably, acute exacerbation of psychosis. Once initiated the therapies were acceptable with no-one ceasing SCIT due to loss of interest and only 10% of participants ceasing CR due to loss of interest. Annual audits of programs found programs established were maintained and facilitators were retained. SCIT and CR programs were successfully implemented in three hospital districts. Several factors impeded participants receiving the recommended "dose" of the programs. The maintenance of the programs in the short term is encouraging in regards to organisational fit. Dissemination of cognitive rehabilitation programs to a service population takes planning. An implementation plan is essential for guiding development and maintenance of programs. These therapies are best suited to people in a stable phase of illness. Service user co-production is recommended to improve recruitment in future studies.

An omalizumab treatment and a high maintenance venom dose may both help to prevent recurrent systemic allergic reactions (SAR) to venom immunotherapy (VIT). The effectiveness of this combination therapy, however, is unclear. We wanted to explore the possibility whether a temporary treatment with the anti-IgE antibody omalizumab combined with a VIT using an elevated maintenance dose of >100 μg venom may establish a permanent tolerance of maintenance VIT. For this retrospective case series, we scoured our institutional data base for patients who had had an insect venom allergy, and in whom it had not been possible to continue VIT because of repeated unstoppable SAR during maintenance VIT. Patients were divided into those who had received the combination therapy (omalizumab group) and those who had not received omalizumab because its costs could not be covered (controls). Guided by the total IgE level and by body weight, omalizumab had been given subcutaneously 5, 3 and 1 weeks before VIT had been restarted. Three to 6 months after an elevated maintenance dose (200-300 μg venom) had been reached, omalizumab had been stopped. Between 2006 and 2011, 15 patients had qualified for an off-label use of omalizumab: 10 patients had received the combination therapy, and 5 patients had remained without such a therapy. The combination therapy leads to a durable tolerance of VIT in all patients even after omalizumab had been discontinued (median of follow-up time 5.8 years, IQR 2.7-8.6 years). Sting challenge tests were tolerated by all of the re-stung omalizumab patients (n = 8). In all controls, VIT had to be stopped permanently due to repeated SARs (P < .001 vs omalizumab group). Combining a temporary omalizumab therapy with an elevated maintenance dose seems a promising approach to achieve a tolerance of treatment in patients with a recurrent SAR to VIT. © 2017 John Wiley & Sons Ltd.

Rising Costs of COPD and the Potential for Maintenance Therapy to Slow the Trend

Background Chronic obstructive pulmonary disease (COPD) affects an estimated 14% of adults in the United States between the ages of 40 and 79 years. This progressive disease is characterized by persistent airflow limitation. The management of patients with COPD is focused on reducing risk factors, relieving symptoms, and preventing exacerbations. Objective To examine the peer-reviewed literature on the impact of maintenance therapy on the direct treatment costs of patients with COPD in the United States. Methods PubMed was searched for articles written in English that were published between 2000 and 2013, using the search terms “COPD,” “economics,” “exacerbation,” “maintenance,” and related terms. Articles reporting the results of longitudinal studies of the costs associated with the management of patients with COPD, the costs associated with hospitalizations for acute exacerbations of COPD, and randomized clinical trials evaluating the effects of maintenance therapy on the incidence of COPD exacerbations were included in this review. Results The search identified a total of 277 articles, and 11 of these articles were deemed appropriate for inclusion in this review. The direct healthcare costs for patients with COPD increased by 38% between 1987 and 2007, and continued to increase by approximately 5% annually between 2006 and 2009. The costs associated with hospital admissions for patients with COPD accounted for the largest absolute increase ($2289 per admission in constant 2007 US dollars). Recent estimates suggest that the aggregate costs associated with the treatment of acute exacerbations are between $3.2 billion and $3.8 billion, and that annual healthcare costs are 10-fold greater for patients with COPD associated with acute exacerbations than for patients with COPD but without exacerbations. The results of 2 large clinical trials of maintenance therapy, including a long-acting cholinergic antagonist or a long-acting beta-2 agonist, showed a 16% to 17% reduction in the incidence of exacerbations compared with placebo. Nevertheless, maintenance therapy remains underutilized, with only 30% to 35% of patients with COPD in private and public health insurance plans receiving prescriptions for maintenance therapy. Conclusions The treatment of acute exacerbations of COPD remains the major driver of increasing healthcare costs associated with this condition. The appropriate use of maintenance therapy has been shown to reduce the incidence of exacerbations and has the potential to reduce overall costs associated with the management of patients with COPD.

The pathogenesis and progression of lung cancer is a complicated process in which many genes take part. But molecular gene testing is typically only performed in advanced-stage non-squamous non-small-cell lung cancer (NSCLC). The value of tyrosine kinase inhibitors (TKI) administration is not widely recognized with respect to early-stage NSCLC. Here, we present a case of a man, heavy smoker who initially presented with stage IA lung adenocarcinoma (LADC). Three years after a lung lobectomy, he was diagnosed with advanced lung squamous cell carcinoma (SCC), according to laboratory, imaging, and pathological examinations. The case initially had an early-stage LADC with an L858R epidermal growth factor receptor (EGFR) mutation. A subsequent advanced SCC bearing EGFR L858R/T790M mutations occurred 3 years after surgery. The comprehensive therapy we utilized, including surgical resection for the early-stage lesion and GP chemotherapy and local radiotherapy as the first line therapy along with gefitinib maintenance treatment for the advanced metachronous second primary tumors (MST). The synthetical therapy, have resulted in our patient with remaining alive and progression free for 4.5 years. This case suggests that changes in molecular pathology should be monitored closely throughout cancer progression to guide personalized therapy and improve prognosis. We further review administration of TKI to early-stage NSCLC and to the metachronous second primary tumors (MST) in survivors.

We report a patient with severe chronic periodontitis requiring regenerative periodontal surgery and different types of prosthesis in the maxillary and mandibular regions. The patient was a 57-year-old woman who presented with the chief complaint of occlusal pain. An initial clinical examination revealed that 73% of sites had a probing depth of ≥4 mm, and 60% of sites exhibiting bleeding on probing. Radiographic examination revealed vertical bone defects in the molar region and widening of the periodontal ligament space around teeth #17 and 24. Initial periodontal therapy was implemented based on a clinical diagnosis of severe chronic periodontitis. Surgical periodontal therapy was subsequently performed at selected sites. Periodontal regenerative therapy using enamel matrix derivative was performed on #14, 15, and 35-37. Tunnel preparation was performed on #46 as it had a 2-wall vertical bony defect and Degree 3 furcation involvement. Other sites with residual periodontal pockets were treated by modified Widman flap surgery. After a re-evaluation, functional rehabilitation was implemented with a removable maxillary partial denture and a fixed mandibular bridge. No further deterioration was observed in the periodontal condition of most of the teeth during a 2-year period of supportive periodontal therapy (SPT). The patient is currently still undergoing SPT and some minor problems remain. However, the results suggest that treatment and subsequent maintenance for severe periodontitis with traumatic occlusion can be successful as long as the appropriate periodontal and prosthodontic treatment is planned and careful SPT carried out.

Continuation/maintenance electroconvulsive therapy has been shown to be effective for prevention of relapse in affective and psychotic disorders. However, there is a limited nubber of studies that investigate clinical management, associated costs, and perceived quality variables. A series of 8 cases included during the first 18 months of the Continuation/Maintenance Electroconvulsive Therapy Program of the Psychiatry Department at 12 de Octubre University Hospital is presented. Clinical variables (Clinical Global Impression-Improvement Scale, length of hospitalization, number of Emergency Department visits, number of urgent admissions) before and after inclusion in the continuation/maintenance electroconvulsive therapy program were compared for each patient, as well as associated costs and perceived quality. After inclusion in the program, 50.0% of patients reported feeling « much better » and 37.5% « moderately better » in the Clinical Global Impression-Improvement Scale. In addition, after inclusion in the continuation/maintenance electroconvulsive therapy program, patients were hospitalized for a total of 349 days, visited the Emergency Department on 3 occasions, and had 2 urgent admissions, compared to 690 days of hospitalization (P = .012), 26 Emergency Department visits (P = .011) and 22 urgent admissions (P = .010) during the same period before inclusion in the program. Associated direct costs per day of admission were reduced to 50.6% of the previous costs, and costs associated with Emergency Department visits were reduced to 11.5% of the previous costs. As regards perceived quality, 87.5% of patients assessed the care and treatment received as being « very satisfactory », and 12.5% as « satisfactory ». This continuation/maintenance electroconvulsive therapy program has shown to be clinically useful and to have a favourable economic impact, as well as high perceived quality.

Data on quality of life (QOL) specifically in maintenance therapy of acute lymphoblastic leukemia (ALL) are minimal. This study was done to assess various items listed in domains of QOL (physical, emotional, social and school health domains) of children with ALL during maintenance therapy, and compare the same with those of their siblings and other healthy children. Forty children on maintenance therapy of ALL, 40 siblings and 40 healthy children were assessed for QOL by child self-report using PedsQL 4.0 Generic Core in the local language. Means were computed and compared for each domain with one-way analysis of variance (ANOVA), wherein higher values reflected better QOL. Overall QOL of children with ALL in maintenance therapy (77.16 ± 10.98) was significantly poorer than that of siblings (93.56 ± 4.41) and healthy children (93.02 ± 3.76) (p < 0.001), but their abilities of self-care, household work, exercise, attentiveness, memory and homework were unaffected. There was significantly higher absenteeism due to sickness and hospital visits, and increased emotional problems (fear, anger, sleeping problems) among children with ALL. In the social health domain, children with ALL reported difficulty in maintaining friendships and competing. QOL of siblings was as good as that of healthy children in physical, social and school health domains, but they had increased emotional problems such as anger and sadness. Healthy children reported significantly higher future worries and bullying than children with ALL and siblings. This study validated that the QOL of children with ALL during maintenance therapy was significantly poorer than that of siblings and healthy children. The study identified various items in each domain of QOL that were affected in these children, and thus would assist in guiding healthcare professionals to focus on these specific items so as to improve their overall QOL.

The purpose was to describe the use of valproate therapy for agitation in critically ill patients, examine its safety, and describe its relationship with agitation and delirium. This retrospective cohort study evaluated critically ill adults treated with valproate for agitation from December 2012 through February 2015. Information on valproate prescribing practices and safety was collected. Incidence of agitation, delirium, and concomitant psychoactive medication use was compared between valproate day 1 and valproate day 3. Concomitant psychoactive medication use was analyzed using mixed models. Fifty-three patients were evaluated. The median day of valproate therapy initiation was ICU day 7, and it was continued for a median of 7 days. The median maintenance dose was 1500 mg/d (23 mg/kg/d). The incidence of agitation (96% vs 61%, P < .0001) and delirium (68% vs 49%, P = .012) significantly decreased by valproate day 3. Treatment with opioids (77% vs 65%, P = .02) and dexmedetomidine (47% vs 24%, P = .004) also decreased. In mixed models analyses, valproate therapy was associated with reduced fentanyl equivalents (-185 μg/d, P = .0003) and lorazepam equivalents (-2.1 mg/d, P = .0004). Hyperammonemia (19%) and thrombocytopenia (13%) were the most commonly observed adverse effects. Valproate therapy was associated with a reduction in agitation, delirium, and concomitant psychoactive medication use within 48 hours of initiation. Copyright © 2016 Elsevier Inc.

2003-06-01

The objective of this study was to evaluate the maintenance of treatment goals of a short cognitive-behavioural group treatment programme for the management of somatization disorders in primary care. In a previous controlled 6-month follow-up study, patients with somatization disorders (n=32) improved with respect to illness and somatic preoccupation, hypochondriasis, and medication usage. In the present report the same group of patients were also investigated one-and-a-half year after initial treatment. The long-term follow-up manifested maintained improvement with respect to hypochondriasis. There was additional reduction of anxiety and psychosocial preoccupation, whereas somatization and depression-anxiety scores improved progressively. A short cognitive-behavioural group treatment of psychosomatic patients can be useful in primary care and may manifest maintained or progressive beneficial outcome.

Home-based care in oncology is mainly reserved for patients at the end of life. Regulations regarding home delivery of cytotoxics differ across Europe, with a notable lack of practice guidelines in most countries. This has led to a lack of data addressing the feasibility of home-based administration of cytotoxic chemotherapy. In advanced non-squamous non-small cell lung cancer, pemetrexed is approved as maintenance therapy after first-line chemotherapy. In this setting, patients have the potential to be treated long-term with maintenance therapy, which, in the absence of unacceptable toxicity, is continued until disease progression. The favourable safety profile of pemetrexed and the ease of its administration by 10-minute intravenous infusion every 3 weeks make this drug a suitable candidate for administration in a home setting. Literature and regulations relevant to the home-based delivery of cytotoxic therapy were reviewed, and a phase II feasibility study of home administration of pemetrexed maintenance therapy was designed. At least 50 patients with advanced non-squamous non-small cell lung cancer, Eastern Cooperative Oncology Group performance status 0-1 and no progressive disease after four cycles of platinum-based first-line therapy are required to allow investigation of the feasibility of home-based administration of pemetrexed maintenance therapy (500 mg/m(2) every 3 weeks until progressive disease or unacceptable toxicity). Feasibility is being assessed as adherence to the home-based administration process (primary endpoint), patient safety, impact on patients' quality of life, patient and physician satisfaction with home care, and healthcare resource use and costs. Enrolment of patients from the UK and Sweden, where home-based care is relatively well developed, commenced in December 2011. This feasibility study addresses an important aspect of maintenance therapy, that is, patient comfort during protracted home-based chemotherapy. The study design requires unusual methodology and specific logistics to address outcomes relevant to the home-delivery approach. This article presents a study design that offers a novel and reproducible model for home-based chemotherapy, and provides an up-to-date overview of the literature regarding this type of treatment.

A previous dose-ranging study of foscarnet maintenance therapy for cytomegalovirus retinopathy showed a positive relationship between dose and survival but could not confirm a relationship between dose and time to first progression. This retrospective analysis of data from that study was undertaken to determine whether there was a relationship between dose and progression rates, which reflects the amount of retina destroyed when progression occurs. Patients were randomly given one of two foscarnet maintenance therapy doses (90 mg/kg of body weight/day [FOS-90 group] or 120 mg/kg of body weight/day [FOS-120 group] after induction therapy. Using baseline and follow-up photographs and pre-established definitions and methodology in a masked analysis, posterior progression rates and foveal proximity rates for individual lesions, selected by prospectively defined criteria, were calculated in each patient. Rates were compared between groups. The following median rates were greater for the FOS-90 group (N = 8) than for the FOS-120 group (N = 10): greatest maximum rate at which lesions enlarged in a posterior direction (43.5 vs 12.5 microns/day; P = .002); posterior progression rate for lesions closest to the fovea (42.8 vs 5.5 microns/day; P = .010); and maximum foveal proximity rate for either eye (32.3 vs 3.4 microns/day; P = .031). Patients receiving higher doses of foscarnet have slower rates of progression and therefore less retinal tissue damage during maintenance therapy. A foscarnet maintenance therapy dose of 120 mg/kg of body weight/day instead of 90 mg/kg of body weight/day may help to preserve vision in patients with cytomegalovirus retinopathy.

Adequate maintenance therapy for childhood acute lymphoblastic leukemia (ALL), with 6-mercaptopurine as an essential component, is necessary for retaining durable remission. Interruptions or discontinuations of the therapy due to drug-related toxicities, which can be life threatening, may result in an increased risk of relapse. In this retrospective study including 305 paediatric ALL patients undergoing maintenance therapy, we systematically investigated the individual and combined effects of genetic variants of folate pathway enzymes, as well as of polymorphisms in PACSIN2 and ITPA, on drug-induced toxicities by applying a multi-analytical approach including logistic regression (LR), classification and regression tree (CART) and generalized multifactor dimensionality reduction (GMDR). In addition to the TPMT genotype, confirmed to be a major determinant of drug related toxicities, we identified the PACSIN2 rs2413739TT genotype as being a significant risk factor for 6-MP-induced toxicity in wild-type TPMT patients. A gene-gene interaction between MTRR (rs1801394) and MTHFR (rs1801133) was detected by GMDR and proved to have an independent effect on the risk of stomatitis, as shown by LR analysis. To our knowledge, this is the first study showing PACSIN2 genotype association with hematological toxicity in ALL patients undergoing maintenance therapy.

Periodontal maintenance (PM) is a critical factor in the long-term success of both periodontal and dental implant therapy. Studies have shown both modern periodontal and dental implant therapies are effective in maintaining natural teeth and replacing lost teeth, respectively. However, without a regular program of clinical reevaluation, plaque control, oral hygiene instruction, and reassessment of biomechanical factors, the benefits of treatment often are lost and inflammatory disease in the form of recurrent periodontitis or periimplantitis may result. This article reviews the goals, types, and appropriate frequency of PM in periodontal and dental implant therapy, as well as the incidence and etiology of periimplant disease and strategies for management when recurrent disease develops during the maintenance phase of treatment.

Of 760 AIDS patients seen at San Francisco General Hospital in 1986, 5.7 per cent had retinitis and 2.2 per cent had gastrointestinal disease caused by cytomegalovirus. We reviewed the records of 44 patients treated with ganciclovir for culture-confirmed cytomegalovirus retinal (31 patients) or gastrointestinal disease (17 patients) or both (four patients) in 1986. Retinitis stabilized or improved during initial treatment with ganciclovir in 22 of 27 (81.5 per cent) patients. Following a median 10-day induction course, 16 patients with retinitis continued to have serial ophthalmologic assessments: eight patients were maintained on treatment and eight had maintenance treatment deferred. Before treatment, the two groups were comparable in age, Karnofsky scores, hematologic assessment, visual acuity, and history with respect to Pneumocystis carinii pneumonia. Retinitis did not progress for a median 53.8 days in the immediate maintenance group compared to 18.8 days for the deferred maintenance group (p = 0.01). In 17 patients with CMV gastrointestinal disease, nine of 14 (64 per cent) had resolution of pain and eight of 11 (73 per cent) had resolution of diarrhea when treated initially with ganciclovir. In both retinitis and gastrointestinal disease patients, ganciclovir decreased recovery of CMV from urine and blood markedly. Ganciclovir also caused a decrease in mean absolute neutrophil counts to about half of baseline values; decreases in mean platelet count and hemoglobin were also noted but were less than 25 per cent. Neutropenia severe enough to require dose adjustment (less than 800 cells/microliters) occurred in 31 per cent of patients receiving maintenance ganciclovir.

The dopamine agonist rotigotine has shown efficacy and safety for the treatment of early and advanced Parkinson's disease (PD) in controlled clinical trials. This observational study evaluated rotigotine administration in combination with other antiparkinsonian medication in routine clinical practice. Data were collected by 688 German practice-based neurologists, initiating rotigotine treatment in patients with idiopathic Parkinson's disease. Assessments included rotigotine maintenance dose, changes in concomitant PD medication, changes in sleep quality, and rotigotine tolerability over an observation period of 12-16 weeks. The median rotigotine maintenance dose was 6 mg/24 h (n = 969, full analysis set). The proportion of all other prescribed PD medications declined over the observation period; combination therapy decreased by 18.7%. Daily levodopa intake was markedly reduced by 87 mg (18.9%) in 47.6% of the patients with levodopa documentation; 7% no longer required levodopa after 12-16 weeks. Mean overall sleep quality (PD Sleep Scale item 1) improved by 21.4 points, the occurrence of nocturias (PDSS item 8) by 13.4 points, and 'turning in bed' (Unified Parkinson's Disease Rating Scale part II) by 0.6 points. Drug-related adverse events were reported for 7.9% of all patients (n = 1152, safety population). Application site reactions were the most common adverse events (2.2%) resulting in early discontinuation in 1.4% of patients. In routine clinical practice, treatment initiation with rotigotine transdermal patch was associated with a reduction of other prescribed PD medications and with an improvement of self-reported sleep quality.

Patients with first-episode psychosis of peripartum onset commonly prove to have a mood-disorder diathesis; however, a proportion of cases represent first-episode schizophrenia. We present such a case and discuss the clinical relevance of recognizing this small but important population of new mothers. These patients are at considerable risk of misdiagnosis, resulting in ineffective maintenance therapy, poorer recovery of function, and development of treatment resistance. Accurate diagnosis in the peripartum period will impact treatment decisions and long-term therapy. Clinicians need to be vigilant, especially during maintenance therapy, to identify these patients and ensure appropriate antipsychotic therapy is provided.

Initial therapy of mantle cell lymphoma

Witzig, Thomas E.

2011-01-01

Mantle cell lymphoma is a well-recognized distinct clinicopathologic subtype of B-cell non-Hodgkin lymphoma. The current World Health Organization (WHO) classification subdivides this entity into aggressive and other variants. The disease has a predilection for older males, and patients typically present at an advanced stage with frequent splenomegaly and extranodal involvement including bone marrow, peripheral blood, gastrointestinal, and occasional central nervous system involvement. Early studies of therapy outcomes in this disease revealed that while response rates where high, relapse was expected after a limited period of time. Prolonged survival was uncommon, with initial median survival rates typically in the 3–4-year range. Those with a high proliferative rate, blastoid morphology, and selected clinical features were recognized as having a worse prognosis. Therapeutic approaches have diverged into aggressive therapies with high response rates and promising progression free survival rates, which may be applied to younger healthy patients, and less aggressive approaches. Aggressive therapies include intensive chemotherapy alone or chemotherapy followed by autologous stem cell transplant, which has been shown to be most effective when applied in first remission. Whether these more intense therapies result in improved survival as compared with less aggressive therapies is not well established. Allogeneic transplant has also been investigated, although high treatment-related mortality and the risk of chronic graft versus host disease and the relatively advanced age of this patient population have tempered enthusiasm for this approach. A number of less aggressive therapies have been shown to produce promising results. Consolidation and maintenance strategies are an active area of investigation. A number of newer agents have shown promising activity in relapsed disease, and are being investigated in the front-line setting. Overall survival rates are improving in this disease, with current studies suggesting a median survival of 5 or more years. PMID:23556104

Circulating plasma cells (CPCs) have been detected in patients with multiple myeloma (MM) at various stages of disease and associated with worse outcomes. Little data exist regarding the impact of CPCs at the time of autologous peripheral blood stem cell (PBSC) collection on outcomes, and the impact of maintenance therapy after autologous stem cell transplantation (ASCT) on prognosis in patients with CPC-containing collections. All patients with MM who underwent first ASCT at Fred Hutchinson Cancer Research Center from 2012 to 2015 and had evaluation for CPCs at the time of PBSC collection were included in our analysis. Seven-color flow cytometry was used to detect the presence of CPCs. Kaplan-Meier estimates were used to generate overall survival (OS) and progression-free survival (PFS) rates from the time of ASCT. A multivariate analysis, including receipt of maintenance therapy post-ASCT, high-risk cytogenetics, and international staging system (ISS) stage, was included in a Cox proportional hazards regression model for associations with OS and PFS. We identified 227 patients with MM who underwent ASCT; of these, 144 (63.4%) patients had routine assessment of CPCs at the time of PBSC collection. One hundred seventeen (81.3%) patients did not have CPCs and 27 (18.8%) did have CPCs. The presence of CPCs was highly associated with poorer PFS (P = .031 by log-rank analysis), but did not affect OS. The median PFS for those patients without CPCs was 39.4 months (95% confidence interval [CI], 31.1 to not reached), while the median PFS for those patients with CPCs was 16.5 months (95% CI, 13.7 to not reached). A subgroup analysis of patients achieving VGPR or better at time of collection, showed the median PFS for patients without CPCs was 38.3 months (95% CI, 29 to not reached), as compared with those patients with CPCs, where it was only 16.5 months (95% CI, 12 months to not reached; P = .02). There was no statistically significant difference in PFS or OS among those patients achieving PR at the time of collection. In a Cox proportional hazards model, adjusting for post-ASCT maintenance therapy, high-risk cytogenetics, and ISS stage at time of initial diagnosis, there was a 43% higher risk of progression or death among the patients with CPCs (P = .04). The presence of CPCs at the time of autologous PBSC collection is a negative prognostic factor for risk of early relapse or death despite the advent of novel agents and maintenance strategies. The impact of CPCs was most significant among patients achieving a VGPR or better at time of collection. The presence of CPCs denotes a unique group of high-risk MM patients for whom alternative treatment strategies are needed to overcome resistance to current standard therapies. Copyright © 2018.

Evans, Tracey; Gettinger, Scott; Hensing, Thomas A.; VanDam Sequist, Lecia; Ireland, Belinda; Stinchcombe, Thomas E.

2013-01-01

Background: Stage IV non-small cell lung cancer (NSCLC) is a treatable, but not curable, clinical entity in patients given the diagnosis at a time when their performance status (PS) remains good. Methods: A systematic literature review was performed to update the previous edition of the American College of Chest Physicians Lung Cancer Guidelines. Results: The use of pemetrexed should be restricted to patients with nonsquamous histology. Similarly, bevacizumab in combination with chemotherapy (and as continuation maintenance) should be restricted to patients with nonsquamous histology and an Eastern Cooperative Oncology Group (ECOG) PS of 0 to 1; however, the data now suggest it is safe to use in those patients with treated and controlled brain metastases. Data at this time are insufficient regarding the safety of bevacizumab in patients receiving therapeutic anticoagulation who have an ECOG PS of 2. The role of cetuximab added to chemotherapy remains uncertain and its routine use cannot be recommended. Epidermal growth factor receptor (EGFR) tyrosine kinase inhibitors as first-line therapy are the recommended treatment of those patients identified as having an EGFR mutation. The use of maintenance therapy with either pemetrexed or erlotinib should be considered after four cycles of first-line therapy in those patients without evidence of disease progression. The use of second- and third-line therapy in stage IV NSCLC is recommended in those patients retaining a good PS; however, the benefit of therapy beyond the third-line setting has not been demonstrated. In the elderly and in patients with a poor PS, the use of two-drug, platinum-based regimens is preferred. Palliative care should be initiated early in the course of therapy for stage IV NSCLC. Conclusions: Significant advances continue to be made, and the treatment of stage IV NSCLC has become nuanced and specific for particular histologic subtypes and clinical patient characteristics and according to the presence of specific genetic mutations.

Ketamine Therapy for Treatment-resistant Depression in a Patient with Multiple Sclerosis: A Case Report.

PubMed

Messer, Michael M; Haller, Irina V

2017-01-01

Objective: Depression is a common condition among patients with multiple sclerosis and often becomes resistant to oral antidepressants. We report a patient with multiple sclerosis who developed severe treatment-resistant depression and who was successfully treated with intravenous ketamine over the period of two years. Methods: Ketamine treatment protocol included an initial series of six treatments administered every other day, followed by a maintenance schedule. Ketamine was administered intravenously at 0.5mg/kg of ideal body weight over 40 minutes. Depression symptoms were measured using Beck Depression Index. Results: The patient's Beck Depression Index score prior to initiating ketamine treatment was 38, corresponding to severe depression. Response to treatment, defined as 50-percent reduction in Beck Depression Index score, was observed after five treatments. For this patient, the maintenance schedule ranged from a weekly treatment to one treatment every three weeks. During the two-year observation period, this patient was able to maintain a stable non-depressed mood and had no worsening of her MS symptoms. Conclusion: Ketamine may be an alternative treatment for resistant depression and may have a special use in patients with multiple sclerosis.

Extended Survival after Complete Pathological Response in Metastatic Pancreatic Ductal Adenocarcinoma Following Induction Chemotherapy, Chemoradiotherapy, and a Novel Immunotherapy Agent, IMM-101

Pancreatic ductal adenocarcinoma (PDAC) has an extremely poor prognosis. Median survival for metastatic patients is six to nine months and survivors beyond one year are exceptional. Pancreatic cancer is resistant to conventional chemotherapy and is often diagnosed at advanced stages. However, immunotherapy is a rapidly advancing new treatment modality, which shows promise in many solid tumor types.​ We present a patient with metastatic pancreatic cancer who underwent a synchronous resection of the primary tumour (pancreatoduodenectomy) and metastatic site (left hepatectomy) after multimodality neoadjuvant treatment with gemcitabine, nab-paclitaxel, and immunotherapy backbone with IMM-101 (an intradermally applied immunomodulator), as well as consolidation chemoradiation. Pathology of the specimens showed a complete response in both sites of the disease. The patient remains alive four years from the initial diagnosis and continues on maintenance immunotherapy. This exceptional response to initial chemo-immunotherapy was followed by a novel and off-protocol approach of low-dose capecitabine and IMM-101 as a maintenance strategy. The survival benefit and sustained performance status could set this as a new paradigm for the treatment of oligometastatic pancreatic cancer following response to systemic therapy and immunotherapy.​ PMID:26870619

Glycolytic reprogramming through PCK2 regulates tumor initiation of prostate cancer cells

Zhao, Jiangsha; Li, Jieran; Fan, Teresa W.M.; Hou, Steven X.

2017-01-01

Tumor-initiating cells (TICs) play important roles in tumor progression and metastasis. Identifying the factors regulating TICs may open new avenues in cancer therapy. Here, we show that TIC-enriched prostate cancer cell clones use more glucose and secrete more lactate than TIC-low clones. We determined that elevated levels of phosphoenolpyruvate carboxykinase isoform 2 (PCK2) are critical for the metabolic switch and the maintenance of TICs in prostate cancer. Information from prostate cancer patient databases revealed that higher PCK2 levels correlated with more aggressive tumors and lower survival rates. PCK2 knockdown resulted in low TIC numbers, increased cytosolic acetyl-CoA and cellular protein acetylation. Our data suggest PCK2 promotes tumor initiation by lowering acetyl-CoA level through reducing the mitochondrial tricarboxylic acid (TCA) cycle. Thus, PCK2 is a potential therapeutic target for aggressive prostate tumors. PMID:29137367

Older patients with acute myeloid leukemia (AML) have worse rates of complete remission and shorter overall survival than younger patients. The epigenetic modifier CC-486 is an oral formulation of azacitidine with promising clinical activity in patients with AML in Phase I studies. The Phase III, randomized, double-blind, placebo-controlled QUAZAR AML Maintenance trial (CC-486-AML-001) examines CC-486 maintenance therapy (300 mg/day for 14 days of 28-day treatment cycles) for patients aged ≥55 years with AML in first complete remission. The primary end point is overall survival. Secondary end points include relapse-free survival, safety, health-related quality of life and healthcare resource utilization. This trial will investigate whether CC-486 maintenance can prolong remission and improve survival for older patients with AML.

Thiopurines in inflammatory bowel disease revisited

Bär, Florian; Sina, Christian; Fellermann, Klaus

2013-01-01

Although a great variety of new drugs have been introduced for the therapy of inflammatory bowel diseases so far, a definite cure of the disease is still out of scope. An anti-inflammatory approach to induce remission followed by maintenance therapy with immunosupressants is still the mainstay of therapy. Thiopurines comprising azathioprine and its active metabolite mercaptopurine as well as tioguanine, are widely used in the therapy of chronic active inflammatory bowel disease (IBD). Their steroid sparing potential and efficacy in remission maintenance are out of doubt. Unfortunately, untoward adverse events are frequently observed and may preclude further administration or be life threatening. This review will focus on new aspects of thiopurine therapy in IBD, its efficacy and safety. PMID:23555158

Fifty-four patients were enrolled: 12 H. pylori-negative and 42 H. pylori-positive patients. The tumor was located more frequently in both the proximal and distal parts of the stomach (P = 0.001), and the percentage of multiple lesions was significantly greater in the H. pylori-negative group (P = 0.046). Forty-seven patients received initial eradication therapy, and 85% (35/41) of H. pylori-positive patients and 50% (3/6) of H. pylori-negative patients achieved complete remission after eradication therapy. The presence of multiple lesions was a predictive factor for unresponsiveness to H. pylori eradication (P = 0.024). The efficacy of eradication therapy (P = 0.133), complete remission (CR) maintenance period, and relapse after eradication therapy were not significantly different between the two groups. Conclusions. H. pylori eradication therapy could be an effective first-line treatment for localized H. pylori-negative gastric MALT lymphoma, especially for single lesions. PMID:27034656

Treatment of adult, noninfectious uveitis remains a challenge for ophthalmologists around the world. The disease accounts for almost 10% of preventable blindness in the US and can be idiopathic or associated with infectious and systemic disorders. Strong evidence is still emerging to indicate that pharmacologic strategies presently used in rheumatologic or autoimmune disease may be translated to the treatment of intraocular inflammation. Corticosteroid monotherapy is widely regarded as wholly inappropriate, due to the unfavorable risk/benefit profile and poor long-term outcomes. Treatment plans have shifted away from low-dose, chronic corticosteroid therapy for maintenance, towards medium- to high-dose therapy for acute inflammation, followed immediately by initiation of immunomodulatory therapy. These therapies follow the 'stepladder approach', whereby least to more aggressive therapies are trialed to induce remission of inflammation, eventually without corticosteroids of any form (topical, local and systemic). This two-part review gives a comprehensive overview of the existing medical treatment options for patients with adult, noninfectious uveitis, as well as important advances for the treatment of ocular inflammation. Part I covers classic immunomodulation and latest information on corticosteroid therapy. The hazard of chronic corticosteroid use for the treatment of adult, noninfectious uveitis is well-documented. Corticosteroid-sparing therapies, which offer a very favorable risk-benefit profile when administered properly, should be substituted.

Mercaptopurine/Methotrexate Maintenance Therapy of Childhood Acute Lymphoblastic Leukemia: Clinical Facts and Fiction

Nielsen, Stine N.; Frandsen, Thomas L.; Nersting, Jacob

2014-01-01

The antileukemic mechanisms of 6-mercaptopurine (6MP) and methotrexate (MTX) maintenance therapy are poorly understood, but the benefits of several years of myelosuppressive maintenance therapy for acute lymphoblastic leukemia are well proven. Currently, there is no international consensus on drug dosing. Because of significant interindividual and intraindividual variations in drug disposition and pharmacodynamics, vigorous dose adjustments are needed to obtain a target degree of myelosuppression. As the normal white blood cell counts vary by patients’ ages and ethnicity, and also within age groups, identical white blood cell levels for 2 patients may not reflect the same treatment intensity. Measurements of intracellular levels of cytotoxic metabolites of 6MP and MTX can identify nonadherent patients, but therapeutic target levels remains to be established. A rise in serum aminotransferase levels during maintenance therapy is common and often related to high levels of methylated 6MP metabolites. However, except for episodes of hypoglycemia, serious liver dysfunction is rare, the risk of permanent liver damage is low, and aminotransferase levels usually normalize within a few weeks after discontinuation of therapy. 6MP and MTX dose increments should lead to either leukopenia or a rise in aminotransferases, and if neither is experienced, poor treatment adherence should be considered. The many genetic polymorphisms that determine 6MP and MTX disposition, efficacy, and toxicity have precluded implementation of pharmacogenomics into treatment, the sole exception being dramatic 6MP dose reductions in patients who are homozygous deficient for thiopurine methyltransferase, the enzyme that methylates 6MP and several of its metabolites. In conclusion, maintenance therapy is as important as the more intensive and toxic earlier treatment phases, and often more challenging. Ongoing research address the applicability of drug metabolite measurements for dose adjustments, extensive host genome profiling to understand diversity in treatment efficacy and toxicity, and alternative thiopurine dosing regimens to improve therapy for the individual patient.

Objective Tofacitinib is an oral Janus kinase inhibitor for the treatment of rheumatoid arthritis. This post hoc analysis evaluated patients receiving tofacitinib monotherapy or combination therapy, as well as those who switched from monotherapy to combination therapy (mono→combo) or vice versa (combo→mono) in long-term extension (LTE) studies. Methods Data were pooled from open-label LTE studies (ORAL Sequel (NCT00413699; ongoing; data collected 14 January 2016) and NCT00661661) involving patients who participated in qualifying index studies. Efficacy outcomes included American College of Rheumatology 20/50/70 rates, change from baseline in Disease Activity Score in 28 joints, erythrocyte sedimentation rate (DAS28-4(ESR)), Clinical Disease Activity Index (CDAI) and Health Assessment Questionnaire-Disability Index and DAS28-4(ESR) and CDAI low disease activity and remission. Safety was evaluated over 96 months. Results Of the 4967 patients treated, 35.4% initiated tofacitinib monotherapy, 64.6% initiated combination therapy, 2.6% were mono→combo switchers and 7.1% were combo→mono switchers. Patients who switched multiple times were excluded. Of those who initiated monotherapy and combination therapy, 87.8% (1543/1757) and 82.0% (2631/3210), respectively, remained on the same regimen throughout the study; efficacy was maintained. Incidence rates (IRs) for serious adverse events with tofacitinib 5 mg and 10 mg twice daily, respectively, were 9.42 and 8.41 with monotherapy and 8.36 and 10.75 with combination therapy; IRs for discontinuations due to AEs were 7.13 and 6.06 with monotherapy and 7.82 and 8.06 with combination therapy (overlapping CIs). For mono→combo and combo→mono switchers, discontinuations due to AEs were experienced by 0.8% and 0.9%, respectively, within 30 days of switching. Conclusion Tofacitinib efficacy as monotherapy or combination therapy was maintained through month 48 and sustained to month 72, with minimal switching of treatment regimens. Safety was consistent over 96 months. Clinical trial registration NCT00413699 (Pre-results) and NCT00661661 (Results). PMID:29435359

To determine whether significant numbers of asthmatic children with initially rated intermittent asthma later suffer poor asthma control and require the addition of controller medications. Inner-city Hispanic children were followed prospectively in an asthma-specific disease management system (Breathmobile) for a period of 2 years. Clinical asthma symptoms, morbidity treatment, and demographic data were collected at each visit. Treatment was based upon National Heart, Lung, and Blood Institute (NHLBI) Expert Panel Report 3 asthma guidelines. Primary outcome was percentage of patients with intermittent asthma who had not well or poorly controlled asthma during subsequent visits and required controller agents. Secondary outcomes were factors associated with the maintenance of asthma control. About 30.9% of the patients with initial rating of intermittent asthma had not well controlled and poorly controlled asthma during subsequent visits and required the addition of controller agents. Factors associated with good asthma control were compliance, no previous emergency room visits and previous visit during spring season. Asthmatic children with intermittent asthma often lose asthma control and require controller therapy. This justifies asthma guideline recommendations to assess asthma control at follow-up visits and adjust therapy accordingly.

The association between inosine triphosphate pyrophosphatase (ITPA) activity and toxicity of 6-mercaptopurine (6-MP) was retrospectively evaluated in 65 Japanese children with acute lymphoblastic leukemia (ALL). Patients with an ITPA activity of less than 126 μmol/h/gHb presented with hepatotoxicity more frequently than those with higher ITPA activity (p<0.01). The average 6-MP dose during maintenance therapy administered to two patients with the ITPA deficiency was lower than that given to the other patients. Measuring ITPA activity is important for ensuring the safety of maintenance therapy for Asians with ALL because thiopurine S-methyl transferase mutations are rare in the Asian population.

Little is known about doctors' treatment preferences for childhood asthma. The aim of this study was to investigate adherence to management guidelines for childhood asthma. One thousand general practitioners (GPs) and paediatric specialists in Australia were invited to take part in a survey, which collected demographic details and explored their familiarity with and adherence to childhood asthma management guidelines. Two hundred doctors (20% response rate) responded and were eligible for inclusion in the survey. Approximately half (54.5%) of the respondents were very familiar with at least one of the childhood asthma management guidelines. The majority of respondents (86.8%) followed guideline recommendations when prescribing initial maintenance therapy for childhood asthma, while 89.2% and 68.0% followed guideline recommendations regarding step-up and step-down therapy respectively. Overall familiarity with childhood asthma management guidelines could be improved. There is scope for improvement in the adherence to these guidelines when prescribing medication in childhood asthma, particularly for step-down therapy.

1999-06-01

A 6-mo-old hand-raised male western lowland gorilla (Gorilla gorilla gorilla) was diagnosed with acute lymphocytic leukemia based on complete blood count and bone marrow cytology. Clinical signs of the disease were pyrexia, abdominal distention, splenomegaly, and lethargy. Acute lymphocytic leukemia has rarely been reported in this species, and therapy was based on human oncologic protocols. Remission induction chemotherapy resulted in complete clearing of leukemia cells from the bone marrow. Consolidation and maintenance chemotherapy followed. Therapy was facilitated by the use of an infusion port for i.v. treatments and an indwelling lumbar catheter for intrathecal therapy. Side effects associated with chemotherapy were inappetence, moderate alopecia, pancytopenia resulting in sepsis, and bleeding tendency. In spite of initial success, the leukemia reappeared 120 days into treatment. The gorilla was euthanized 7 days later when respiratory distress developed. Intensive care by the animal staff was a key factor in the treatment of this gorilla.

Increasing evidence suggests that cancer cell populations contain a small proportion of cells that display stem-like cell properties and which may be responsible for overall tumor maintenance. These cancer stem-like cells (CSCs) appear to have unique tumor-initiating ability and innate survival mechanisms that allow them to resist cancer therapies, consequently promoting relapses. Selective targeting of CSCs may provide therapeutic benefit and several recent reports have indicated this may be possible. In this article, we review drugs targeting CSCs, in selected epithelial cell-derived cancers. Stem Cells 2017;35:839-850. © 2017 AlphaMed Press.

Continuation and maintenance electroconvulsive therapy (c/m ECT) is a long-term treatment option in severely and chronically ill patients with mood disorders, who are unresponsive or intolerant to medication. Due to the current lack of empirical studies, c/m ECT is still a clinical tool with little evidence. We conducted a retrospective analysis of patients' charts who received c/m ECT over a 10-year period. Outcome was measured by comparing the number of pre-c/m ECT and post-c/m ECT hospitalizations, as well as inpatient days per year and mean duration of hospital stays. In 19 patients (63% female; mean age 53.5 ± 12.0 years) with either bipolar (42%) or unipolar (58%) mood disorder, with the majority of patients suffering from a depressive episode at hospital admission (95%), c/m ECT was initiated after a successful series of ECT. In a 5-year interval before and after starting c/m ECT the number of hospitalizations per year (0.87 vs. 0.28, p < 0.001), inpatient days per year (30.8 vs. 4.5 days, p < 0.001), as well as the mean duration of hospital days (30.5 vs. 16.7 days, p = 0.02) decreased significantly. Our data support previous results showing that c/m ECT is an efficacious option in treating and favourably altering the course of therapy-resistant affective disorders. Further research using a controlled study design and larger sample sizes are needed to convincingly define indication and performance of c/m ECT.

Relapse following successful electroconvulsive therapy for major depression: a meta-analysis.

High rates of early relapse following electroconvulsive therapy (ECT) are typically reported in the literature. Current treatment guidelines offer little information to clinicians on the optimal nature of maintenance therapy following ECT. The aim of this study was to provide a systematic overview of the existing evidence regarding post-ECT relapse. A keyword search of electronic databases was performed for studies appearing in the peer-reviewed literature before January 2013 reporting on relapse rates in responders to an acute course of ECT administered for a major depressive episode. Meta-analyses were performed where appropriate. Thirty-two studies with up to 2 years' duration of follow-up were included. In modern era studies of continuation pharmacotherapy, 51.1% (95% CI=44.7-57.4%) of patients relapsed by 12 months following successful initial treatment with ECT, with the majority (37.7%, 95% CI=30.7-45.2%) relapsing within the first 6 months. The 6-month relapse rate was similar in patients treated with continuation ECT (37.2%, 95% CI=23.4-53.5%). In randomized controlled trials, antidepressant medication halved the risk of relapse compared with placebo in the first 6 months (risk ratio=0.49, 95% CI=0.39-0.62, p<0.0001, number needed to treat=3.3). Despite continuation therapy, the risk of relapse within the first year following ECT is substantial, with the period of greatest risk being the first 6 months. The largest evidence base for efficacy in post-ECT relapse prevention exists for tricyclic antidepressants. Published evidence is limited or non-existent for commonly used newer antidepressants or popular augmentation strategies. Maintenance of well-being following successful ECT needs to be improved.

To assess the effects of five-drug combination therapy on HIV-1 load in lymph nodes and subsequent maintenance with four and three drugs. Ten pharmacotherapeutically naive patients received a combination of zidovudine, lamivudine, didanosine, ritonavir, and saquinavir for 24 weeks, then zidovudine, lamivudine, didanosine, and saquinavir for the next 24 weeks, and finally zidovudine, lamivudine, and saquinavir for the last 24 weeks. HIV-1 RNA in lymph nodes was measured using quantitative polymerase chain reaction (PCR) at baseline, after 12, 24, 48, and 78 weeks. Plasma HIV-1 RNA, proviral DNA in peripheral blood mononuclear cells (PBMCs), circulating lymphocyte subsets, and protease inhibitor levels in blood were also regularly measured. Genotypic resistance was assessed in the different compartments in 2 patients who were failed by therapy. HIV-1 RNA decreased in lymph nodes in 9 patients and was stable in 1 despite initial control of plasma replication <20 copies/ml in each patient. Lymph node levels rebounded in 1 patient at week 72 as a result of lack of adherence and remained stable in the 8 others despite maintenance regimens. This represents a mean drop of -3.17 log in lymph nodes for the 8 patients maintaining undetectable viremia at 72 weeks. In the patient with stable lymph node viral RNA, selection of the M184V mutation was demonstrated at this level before detection in plasma and low blood saquinavir levels were found throughout the study. Continuous improvements in immune parameters were observed in all cases, although PBMC proviral DNA levels either showed a continuous decrease or stabilized to a plateau. More complex regimens do not perform better in lymph nodes than classic triple therapy. The persistence of HIV-1 RNA in lymph nodes could be related with cellular resistance mechanisms rather than an insufficient potency of the regimens.

How to select among available options for the treatment of multiple myeloma.

The introduction of novel agents (thalidomide, bortezomib and lenalidomide) in the frontline therapy of multiple myeloma has markedly improved the outcome both in younger patients who are candidates for high-dose therapy plus autologous stem-cell transplantation (HDT/ASCT) and in elderly patients. In the HDT/ASCT paradigm, novel agents may be used as induction therapy or after HDT/ASCT as consolidation and/or maintenance therapy. It is now possible to achieve up to 70% complete plus very good partial remission after HDT/ASCT and 70% 3-year progression-free survival (PFS). However long-term non-intensive therapy may also yield high response rates and prolonged PFS. Randomized trials comparing these two strategies are underway. In elderly patients, six randomized studies show the benefit of adding thalidomide to melphalan-prednisone (MP). a large randomized trial has also shown that the combination of bortezomib-MP is superior to MP for all parameters measuring the response and outcome. Finally, the role of maintenance is currently evaluated and a randomized trial shows that low-dose lenalidomide maintenance prolongs PFS.

Combined abuse of clonidine and amitriptyline in a patient on buprenorphine maintenance treatment.

Buprenorphine/naloxone maintenance therapy is often prescribed in primary care to treat opioid dependence. Previous reports have described concomitant abuse of opioids and clonidine. In this case, a primary care patient on buprenorphine/naloxone maintenance therapy demonstrating altered mental status, hallucinations, falls, and rebound hypertension was found to be concomitantly abusing clonidine and amitryptyline, which share metabolic pathways with buprenorphine. Clinicians should be aware of patients' combining amitryptyline, clonidine, and gabapentin with buprenorphine to achieve a mood altering state, avoid co-prescribing them if possible, and maintain communication with pharmacies and other providers when they are prescribed.

Continuation maintenance treatment with pemetrexed is approved by current clinical guidelines as a category 2A recommendation after induction therapy with cisplatin and pemetrexed chemotherapy (CP strategy) for patients with advanced nonsquamous non-small-cell lung cancer (NSCLC). However, the cost-effectiveness of the treatment remains unclear. We completed a trial-based assessment, from the perspective of the Chinese health care system, of the cost-effectiveness of maintenance pemetrexed treatment after a CP strategy for patients with advanced nonsquamous NSCLC. A Markov model was developed to estimate costs and benefits. It was based on a clinical trial that compared continuation maintenance pemetrexed therapy plus best supportive care (BSC) versus placebo plus BSC after a CP strategy for advanced nonsquamous NSCLC. Sensitivity analyses were conducted to assess the stability of the model. The model base case analysis suggested that continuation maintenance pemetrexed therapy after a CP strategy would increase benefits in a 1-, 2-, 5-, or 10-year time horizon, with incremental costs of $183,589.06, $126,353.16, $124,766.68, and $124,793.12 per quality-adjusted life-year gained, respectively. The most sensitive influential variable in the cost-effectiveness analysis was the utility of the progression-free survival state, followed by proportion of patients with postdiscontinuation therapy in both arms, proportion of BSC costs for PFS versus progressed survival state, and cost of pemetrexed. Probabilistic sensitivity analysis indicated that the cost-effective probability of adding continuation maintenance pemetrexed therapy to BSC was zero. One-way and probabilistic sensitivity analyses revealed that the Markov model was robust. Continuation maintenance of pemetrexed after a CP strategy for patients with advanced nonsquamous NSCLC is not cost-effective based on a recent clinical trial. Decreasing the price or adjusting the dosage of pemetrexed may be a better option for meeting the treatment demands of Chinese patients. Copyright © 2013 Elsevier HS Journals, Inc.

The First-Line Erbitux in Lung Cancer (FLEX) trial showed that the addition of cetuximab to chemotherapy followed by weekly cetuximab maintenance significantly improved survival in the first-line treatment of advanced non-small cell lung cancer (NSCLC). The phase IIIb NSCLC Erbitux Trial (NEXT) trial (NCT00820755) investigated the efficacy and safety of weekly and every 2 weeks cetuximab maintenance therapy in this setting. Patients were treated with platinum-based chemotherapy plus cetuximab, and those progression-free after four to six cycles were randomized to every 2 weeks (500 mg/m(2)) or weekly (250 mg/m(2)) cetuximab maintenance. Randomization was stratified for tumor histology and response status. The primary endpoint for a regimen would be reached if the lower boundary of the 95 % confidence interval (CI) for the 1-year survival rate exceeded 55 %. A planned 480 patients were to be randomized. However, enrollment was curtailed following a negative opinion from the European Medicines Agency with regard to the use of cetuximab in this setting. After combination therapy, 311/583 (53.3 %) patients without progression were randomized to maintenance therapy: 157 to every 2 weeks cetuximab and 154 to weekly cetuximab. Baseline characteristics were balanced between these groups and exposure to cetuximab was similar. The 1-year survival rate was 62.8 % (95 % CI, 54.7-70.0) for every 2 weeks cetuximab and 64.4 % (95 % CI, 56.2-71.4) for weekly cetuximab. Safety profiles were similar, manageable, and in line with expectations. Therefore, in patients with advanced NSCLC who were progression-free after four to six cycles of first-line chemotherapy plus cetuximab, weekly and every 2 weeks cetuximab maintenance therapy were associated with similar survival outcomes.

Neurosarcoidosis is a rare and aggressive variant of systemic sarcoidosis which may result in hypothalamic-pituitary dysfunction. We report a case of hypothalamic hypopituitarism secondary to neurosarcoidosis complicated by adipsic diabetes insipidus (ADI). Initiation of anti-tumour necrosis factor-α (TNF-α) therapy resulted in both radiological disease remission and recovery of osmoregulated thirst appreciation after 3 months. A 22-year-old man was referred to the endocrinology service with profound weight gain, polyuria and lethargy. Biochemical testing confirmed anterior hypopituitarism while posterior pituitary failure was confirmed by hypotonic polyuria responding to desmopressin. Magnetic resonance imaging (MRI) demonstrated extensive hypothalamic infiltration; neurosarcoidosis was confirmed histologically after excisional cervical lymph node biopsy. Osmoregulated thirst appreciation was normal early in the disease course despite severe hypotonic polyuria. However, subsequent subjective loss of thirst appreciation and development of severe hypernatraemia in the setting of normal cognitive function indicated onset of ADI. Clinical management involved daily weighing, regular plasma sodium measurement, fixed daily fluid intake and oral desmopressin. We initiated immunosuppressive therapy with pulsed intravenous anti-TNF-α therapy (infliximab) after multidisciplinary team consultation. Infliximab therapy resulted in successful radiological disease remission and complete recovery of osmoregulated thirst appreciation. This was confirmed by subjective return of thirst response and maintenance of plasma sodium in the normal range in the absence of close biochemical monitoring. © The Author 2013.

Although thyroid hormone deficiency, either clinical or subclinical, is an established risk factor for cardiovascular disease, coronary ischemia in a premenopausal woman in her 30s is relatively rare. A 38-year-old woman was referred to our hospital with severe breathlessness and depressed consciousness. Physical examination found facial, abdominal, and pretibial edema; coarse hair, hoarse voice, and dry skin; engorged jugular veins; a distant heart sound; and reduced bilateral entry of air into the chest. Laboratory examinations revealed severe hypothyroidism, hyperlipidemia, and elevated serum levels of carcinoembryonic antigen (CEA) and carbohydrate antigen 125 (CA125). A computed tomography scan showed massive pleural and pericardial effusions. After 3 months of levothyroxine replacement therapy (initial dose: 12.5 microg/d; maintenance dose: 125 microg/d), all abnormal laboratory values associated with hypothyroidism returned to within normal ranges, with the exception of a transient and paradoxical rise in serum thyroid-stimulating hormone levels. However, 3 weeks after the initiation of therapy, the patient reported intermittent chest pains during the course of therapy, and a coronary artery angiogram revealed diffuse stenosis of all 3 branches. The patient underwent coronary artery bypass grafting, with subsequent improvement in coronary perfusion. Careful cardiovascular evaluation is recommended before the start of thyroid hormone replacement therapy. In addition, care should be taken in the interpretation of serum biomarkers of malignancy (eg, CEA, CA125) in patients with myxedema, as values may be elevated in a hypothyroid state. Long-standing hypothyroidism may be associated with severe coronary atherosclerosis, even in a relatively young, premenopausal woman. The potential adverse cardiovascular effects of thyroid hormone must be considered during replacement therapy, even in relatively young patients.

Home administration of maintenance pemetrexed for patients with advanced non-squamous non-small cell lung cancer: rationale, practicalities and phase II feasibility study design

PubMed Central

2013-01-01

Background Home-based care in oncology is mainly reserved for patients at the end of life. Regulations regarding home delivery of cytotoxics differ across Europe, with a notable lack of practice guidelines in most countries. This has led to a lack of data addressing the feasibility of home-based administration of cytotoxic chemotherapy. In advanced non-squamous non-small cell lung cancer, pemetrexed is approved as maintenance therapy after first-line chemotherapy. In this setting, patients have the potential to be treated long-term with maintenance therapy, which, in the absence of unacceptable toxicity, is continued until disease progression. The favourable safety profile of pemetrexed and the ease of its administration by 10-minute intravenous infusion every 3 weeks make this drug a suitable candidate for administration in a home setting. Methods Literature and regulations relevant to the home-based delivery of cytotoxic therapy were reviewed, and a phase II feasibility study of home administration of pemetrexed maintenance therapy was designed. At least 50 patients with advanced non-squamous non-small cell lung cancer, Eastern Cooperative Oncology Group performance status 0–1 and no progressive disease after four cycles of platinum-based first-line therapy are required to allow investigation of the feasibility of home-based administration of pemetrexed maintenance therapy (500 mg/m2 every 3 weeks until progressive disease or unacceptable toxicity). Feasibility is being assessed as adherence to the home-based administration process (primary endpoint), patient safety, impact on patients’ quality of life, patient and physician satisfaction with home care, and healthcare resource use and costs. Enrolment of patients from the UK and Sweden, where home-based care is relatively well developed, commenced in December 2011. Discussion This feasibility study addresses an important aspect of maintenance therapy, that is, patient comfort during protracted home-based chemotherapy. The study design requires unusual methodology and specific logistics to address outcomes relevant to the home-delivery approach. This article presents a study design that offers a novel and reproducible model for home-based chemotherapy, and provides an up-to-date overview of the literature regarding this type of treatment.

Drug doses, blood levels of drug metabolites and myelotoxicity during 6-mercaptopurine/methotrexate (MTX) maintenance therapy were registered for 59 adolescents (>or=10 years) and 176 non-adolescents (<10 years) with B-cell precursor acute lymphoblastic leukemia (ALL) and a white blood cell count (WBC) <50 x 10(9)/l at diagnosis. Event-free survival was lower for adolescents than non-adolescents (pEFS(12y):0.71 vs 0.83, P=0.04). For adolescents staying in remission, the mean WBC during maintenance therapy (mWBC) was related to age (r(S)=0.36, P=0.02), which became nonsignificant for those who relapsed (r(S)=0.05, P=0.9). The best-fit multivariate Cox regression model to predict risk of relapse included mWBC and thiopurine methyltransferase activity, which methylates mercaptopurine and reduces the intracellular availability of cytotoxic 6-thioguanine nucleotides (coefficient: 0.11, P=0.02). The correlation of mWBC to the risk of relapse was more pronounced for adolescents (coefficient=0.65, P=0.003) than for non-adolescents (coefficient=0.42, P=0.04). Adolescents had higher mean neutrophil counts (P=0.002) than non-adolescents, but received nonsignificantly lower mercaptopurine and MTX doses during maintenance therapy. Red blood cell MTX levels were significantly related to the dose of MTX among adolescents who stayed in remission (r(S)=0.38, P=0.02), which was not the case for those who developed a relapse (r(S)=0.15, P=0.60). Thus, compliance to maintenance therapy may influence the risk of relapse for adolescents with ALL.

OBJECTIVE: To assess asthma patients in Brazil in terms of the level of asthma control, compliance with maintenance treatment, and the use of rescue medication. METHODS: We used data from a Latin American survey of a total of 400 asthma patients in four Brazilian state capitals, all of whom completed a questionnaire regarding asthma control and treatment. RESULTS: In that sample, the prevalence of asthma was 8.8%. Among the 400 patients studied, asthma was classified, in accordance with the Global Initiative for Asthma criteria, as controlled, partially controlled, and uncontrolled in 37 (9.3%), 226 (56.5%), and 137 (34.3%), respectively. In those three groups, the proportion of patients on maintenance therapy in the past four weeks was 5.4%, 19.9%, and 41.6%, respectively. The use of rescue medication was significantly more common in the uncontrolled asthma group (86.9%; p < 0.001). CONCLUSIONS: Our findings suggest that, in accordance with the established international criteria, asthma is uncontrolled in the vast majority of asthma patients in Brazil. Maintenance medications are still underutilized in Brazil, and patients with partially controlled or uncontrolled asthma are more likely to use rescue medications and oral corticosteroids.

Background Lower percentages of CD4+ T lymphocytes are associated with adverse clinical outcomes among children and adolescents infected with human immunodeficiency virus (HIV). CD4+ lymphocyte percentage generally increases with receipt of highly active antiretroviral therapy (HAART), but long-term follow-up is required to assess whether these increases in CD4+ cell percentage are maintained and whether they lead to normal CD4+ cell percentages in children with severe immunosuppression. Methods The study population included 1236 children and adolescents perinatally infected with HIV who were enrolled in a US-based multicenter prospective cohort study (Pediatric AIDS Clinical Trials Group 219/219C) and who were not receiving HAART at study initiation. We estimated the effects of HAART, HAART with protease inhibitors, and HAART with nonnucleoside reverse-transcriptase inhibitors on CD4+ cell percentage, using marginal structural models to account for confounding by severity. Results Initiation of any type of HAART increased CD4+ cell percentage by 2.34% (95% confidence interval, 1.35%–3.33%) in the first year, relative to noninitiation of HAART. The substantial increases in CD4+ cell percentage observed after the first year of experience with these combination therapies were followed by relatively smaller increases that continued for 5 years after initiation. Although larger increases in CD4+ cell percentage were observed among children with a greater degree of immunosuppression at baseline, the mean CD4+ cell percentage after 5 years of HAART did not reach normal levels. Conclusions Our study supports the initiation of HAART in children before severe immunosuppression occurs for long-term maintenance of normal CD4+ cell percentages. This beneficial result must be weighed against the evidence of potential adverse events associated with the prolonged use of such therapy. PMID:18426371

Expression IV survey evaluated the patients' expectations to a maintenance therapy. From January 2015 to March 2016, 401 French patients, in first line or recurrent disease, answered a 24-items anonymous questionnaire. The results were specifically analyzed according to the demographic characteristics and treatment lines. Among the patients, 62% had already been informed about maintenance therapy. Thirty-seven percent of patients received a maintenance treatment: 111 patients during first line and 39 patients in relapse. Expectations of patients were: 1) the chance of cure (73%), 2) the tumor shrinkage (36%), 3) quality of life improvement (35%) and 4) tumor growth reduction (27%). Among the responders, 42% were willing to take the treatment for 6-24 months, 20% for 24-60 months and 38% until tumor progression. 64% of patients expected more than a 6 months progression-free survival. Patients older than 70 years were less informed than their younger counterparts (48% vs 66%) and had lesser hope for cure with maintenance treatment (60% vs 77%). Patients in relapse had more expectation than patients in remission (tumor shrinkage: 47% vs 22%, slowing of tumor growth: 37% vs 15%, improving the progression-free survival of more than 6 months: 71% vs 53%, respectively). Among patients, 48% in relapse consented to take a treatment until progression vs 24% of patients in remission. This sub-analysis in French patients demonstrate a gap between the efficacy of maintenance therapy and the patients' expectations in ovarian cancer, particularly in relapsing disease justifying better information and explanations.

Patients with mild asthma often rely on inhaled short-acting β 2 -agonists for symptom relief and have poor adherence to maintenance therapy. Another approach might be for patients to receive a fast-acting reliever plus an inhaled glucocorticoid component on an as-needed basis to address symptoms and exacerbation risk. We conducted a 52-week, double-blind, multicenter trial involving patients 12 years of age or older who had mild asthma and were eligible for treatment with regular inhaled glucocorticoids. Patients were randomly assigned to receive twice-daily placebo plus budesonide-formoterol (200 μg of budesonide and 6 μg of formoterol) used as needed or budesonide maintenance therapy with twice-daily budesonide (200 μg) plus terbutaline (0.5 mg) used as needed. The primary analysis compared budesonide-formoterol used as needed with budesonide maintenance therapy with regard to the annualized rate of severe exacerbations, with a prespecified noninferiority limit of 1.2. Symptoms were assessed according to scores on the Asthma Control Questionnaire-5 (ACQ-5) on a scale from 0 (no impairment) to 6 (maximum impairment). A total of 4215 patients underwent randomization, and 4176 (2089 in the budesonide-formoterol group and 2087 in the budesonide maintenance group) were included in the full analysis set. Budesonide-formoterol used as needed was noninferior to budesonide maintenance therapy for severe exacerbations; the annualized rate of severe exacerbations was 0.11 (95% confidence interval [CI], 0.10 to 0.13) and 0.12 (95% CI, 0.10 to 0.14), respectively (rate ratio, 0.97; upper one-sided 95% confidence limit, 1.16). The median daily metered dose of inhaled glucocorticoid was lower in the budesonide-formoterol group (66 μg) than in the budesonide maintenance group (267 μg). The time to the first exacerbation was similar in the two groups (hazard ratio, 0.96; 95% CI, 0.78 to 1.17). The change in ACQ-5 score showed a difference of 0.11 units (95% CI, 0.07 to 0.15) in favor of budesonide maintenance therapy. In patients with mild asthma, budesonide-formoterol used as needed was noninferior to twice-daily budesonide with respect to the rate of severe asthma exacerbations during 52 weeks of treatment but was inferior in controlling symptoms. Patients in the budesonide-formoterol group had approximately one quarter of the inhaled glucocorticoid exposure of those in the budesonide maintenance group.

In patients with mild asthma, as-needed use of an inhaled glucocorticoid plus a fast-acting β 2 -agonist may be an alternative to conventional treatment strategies. We conducted a 52-week, double-blind trial involving patients 12 years of age or older with mild asthma. Patients were randomly assigned to one of three regimens: twice-daily placebo plus terbutaline (0.5 mg) used as needed (terbutaline group), twice-daily placebo plus budesonide-formoterol (200 μg of budesonide and 6 μg of formoterol) used as needed (budesonide-formoterol group), or twice-daily budesonide (200 μg) plus terbutaline used as needed (budesonide maintenance group). The primary objective was to investigate the superiority of as-needed budesonide-formoterol to as-needed terbutaline with regard to electronically recorded weeks with well-controlled asthma. A total of 3849 patients underwent randomization, and 3836 (1277 in the terbutaline group, 1277 in the budesonide-formoterol group, and 1282 in the budesonide maintenance group) were included in the full analysis and safety data sets. With respect to the mean percentage of weeks with well-controlled asthma per patient, budesonide-formoterol was superior to terbutaline (34.4% vs. 31.1% of weeks; odds ratio, 1.14; 95% confidence interval [CI], 1.00 to 1.30; P=0.046) but inferior to budesonide maintenance therapy (34.4% and 44.4%, respectively; odds ratio, 0.64; 95% CI, 0.57 to 0.73). The annual rate of severe exacerbations was 0.20 with terbutaline, 0.07 with budesonide-formoterol, and 0.09 with budesonide maintenance therapy; the rate ratio was 0.36 (95% CI, 0.27 to 0.49) for budesonide-formoterol versus terbutaline and 0.83 (95% CI, 0.59 to 1.16) for budesonide-formoterol versus budesonide maintenance therapy. The rate of adherence in the budesonide maintenance group was 78.9%. The median metered daily dose of inhaled glucocorticoid in the budesonide-formoterol group (57 μg) was 17% of the dose in the budesonide maintenance group (340 μg). In patients with mild asthma, as-needed budesonide-formoterol provided superior asthma-symptom control to as-needed terbutaline, assessed according to electronically recorded weeks with well-controlled asthma, but was inferior to budesonide maintenance therapy. Exacerbation rates with the two budesonide-containing regimens were similar and were lower than the rate with terbutaline. Budesonide-formoterol used as needed resulted in substantially lower glucocorticoid exposure than budesonide maintenance therapy.

Refractory Immune Thrombocytopenic Purpura and Cytomegalovirus Infection: A Call for a Change in the Current Guidelines.

Immune thrombocytopenic purpura (ITP) is characterized by a decreased platelet count caused by excess destruction of platelets and inadequate platelet production. In many cases, the etiology is not known, but the viral illness is thought to play a role in the development of some cases of ITP. The current (2011) American Society of Hematology ITP guidelines recommend initial diagnostic studies to include testing for HIV and Hepatitis C. The guidelines suggest that initial treatment consist of observation, therapy with corticosteroids, IVIG or anti D. Most cases respond to the standard therapy such that the steroids may be tapered and the platelet counts remain at a hemostatically safe level. Some patients with ITP are dependent on long-term steroid maintenance, and the thrombocytopenia persists with the tapering of the steroids. Recent case reports demonstrate that ITP related to cytomegalovirus (CMV) can persist in spite of standard therapy and that antiviral therapy may be indicated. Herein we report a case of a 26-year-old female with persistent ITP that resolved after the delivery of a CMV-infected infant and placenta. Furthermore, we review the current literature on CMV-associated ITP and propose that the current ITP guidelines be amended to include assessment for CMV, even in the absence of signs and symptoms, as part of the work-up for severe and refractory ITP, especially prior to undergoing an invasive procedure such as splenectomy.

Most patients with gastroesophageal reflux disease experience symptomatic relapse after stopping acid-suppressive medication. The aim of this study was to compare willingness to continue treatment with esomeprazole on-demand versus continuous maintenance therapy for symptom control in patients with non-erosive reflux disease (NERD) after 6 months. This multicenter, open-label, randomized, parallel-group study enrolled adults with NERD who were heartburn-free after 4 weeks' treatment with esomeprazole 20 mg daily. Patients received esomeprazole 20 mg daily continuously or on-demand for 6 months. The primary variable was discontinuation due to unsatisfactory treatment. On-demand treatment was considered non-inferior if the upper limit of the one-sided 95 % confidence interval (CI) for the difference between treatments was <10 %. Of 877 patients enrolled, 598 were randomized to maintenance treatment (continuous: n = 297; on-demand: n = 301). Discontinuation due to unsatisfactory treatment was 6.3 % for on-demand and 9.8 % for continuous treatment (difference -3.5 % [90 % CI: -7.1 %, 0.2 %]). In total, 82.1 and 86.2 % of patients taking on-demand and continuous therapy, respectively, were satisfied with the treatment of heartburn and regurgitation symptoms, a secondary variable (P = NS). Mean study drug consumption was 0.41 and 0.91 tablets/day, respectively. Overall, 5 % of the on-demand group developed reflux esophagitis versus none in the continuous group (P < 0.0001). The Gastrointestinal Symptom Rating Scale Reflux dimension was also improved for continuous versus on-demand treatment. Esomeprazole was well tolerated. In terms of willingness to continue treatment, on-demand treatment with esomeprazole 20 mg was non-inferior to continuous maintenance treatment and reduced medication usage in patients with NERD who had achieved symptom control with initial esomeprazole treatment.

Objective Short-term efficacy of induction therapy with intravenous immunoglobulin (Ig) in patients with chronic inflammatory demyelinating polyneuropathy (CIDP) is well established. However, data of previous studies on maintenance therapy were limited up to 24-week treatment period. We aimed to investigate the efficacy and safety of longer-term intravenous Ig therapy for 52 weeks. Methods This study was an open-label phase 3 clinical trial conducted in 49 Japanese tertiary centres. 49 patients with CIDP who fulfilled diagnostic criteria were included. After an induction intravenous Ig therapy (0.4 g/kg/day for five consecutive days), maintenance dose intravenous Ig (1.0 g/kg) was given every 3 weeks for up to 52 weeks. The primary outcome measures were the responder rate at week 28 and relapse rate at week 52. The response and relapse were defined with the adjusted Inflammatory Neuropathy Cause and Treatment scale. Results At week 28, the responder rate was 77.6% (38/49 patients; 95% CI 63% to 88%), and the 38 responders continued the maintenance therapy. At week 52, 4 of the 38 (10.5%) had a relapse (95% CI 3% to 25%). During 52 weeks, 34 (69.4%) of the 49 enrolled patients had a maintained improvement. Adverse events were reported in 94% of the patients; two patients (66-year-old and 76-year-old men with hypertension or diabetes) developed cerebral infarction (lacunar infarct with good recovery), and the other adverse effects were mild and resolved by the end of the study period. Conclusions Maintenance treatment with 1.0 g/kg intravenous Ig every 3 weeks is an efficacious therapy for patients with CIDP, and approximately 70% of them had a sustained remission for 52 weeks. Thrombotic complications should be carefully monitored, particularly in elderly patients with vascular risk factors. Trial registration number ClinicalTrials.gov (NCT01824251). PMID:28768822

We performed a randomised pilot trial of PerMIT, a novel decision support tool for genotype-based warfarin initiation and maintenance dosing, to assess its efficacy for improving warfarin management. We prospectively studied 26 subjects to compare PerMIT-guided management with routine anticoagulation service management. CYP2C9 and VKORC1 genotype results for 13 subjects randomly assigned to the PerMIT arm were recorded within 24 hours of enrolment. To aid in INR interpretation, PerMIT calculates estimated loading and maintenance doses based on a patient's genetic and clinical characteristics and displays calculated S-warfarin plasma concentrations based on planned or administered dosages. In comparison to control subjects, patients in the PerMIT study arm demonstrated a 3.6-day decrease in the time to reach a stabilised INR within the target therapeutic range (4.7 vs. 8.3 days, p = 0.015); a 12.8% increase in time spent within the therapeutic interval over the first 25 days of therapy (64.3% vs. 55.3%, p = 0.180); and a 32.9% decrease in the frequency of warfarin dose adjustments per INR measurement (38.3% vs. 57.1%, p = 0.007). Serial measurements of plasma S-warfarin concentrations were also obtained to prospectively evaluate the accuracy of the pharmacokinetic model during induction therapy. The PerMIT S-warfarin plasma concentration model estimated 62.8% of concentrations within 0.15 mg/l. These pilot data suggest that the PerMIT method and its incorporation of genotype/phenotype information may help practitioners increase the safety, efficacy, and efficiency of warfarin therapeutic management.

Methadone maintenance therapy (MMT) is crucial for HIV prevention and treatment in people who inject opioids. In Malaysia, a large proportion of the prison population is affected by both HIV and opioid use disorders. This study assessed individual preferences and factors associated with interest in receiving MMT among male prisoners meeting criteria for opioid dependence in Malaysia. A convenience sample of 96 HIV-positive and 104 HIV-negative incarcerated men who met pre-incarceration criteria for opioid dependence was interviewed using a structured questionnaire to examine participant characteristics and attitudes toward MMT. Factors associated with interest in prison-based MMT initiation were identified using logistic regression analysis. Among all participants, 85 (42.5%) were interested in receiving MMT within prison. Independent correlates of interest in prison-based MMT were being previously married (AOR=4.15, 95% CI: 1.15, 15.02), previously incarcerated (AOR=5.68, 95% CI: 1.54, 21.02), depression (AOR=3.66, 95% CI: 1.68, 7.98), daily heroin use in the 30days prior to incarceration (AOR=5.53, 95% CI: 1.65, 18.58), and more favorable attitudes toward MMT (AOR=19.82, 95% CI: 6.07, 64.74). Overall, interest in receiving prison-based MMT was low, and was associated with adverse social, mental health, and drug use consequences. Incarceration provides a unique opportunity to initiate MMT for those who need it, however, optimal scale-up efforts must be systemic and address modifiable factors like improving attitudes toward and motivation for MMT. Informed or shared decision-making tools may be useful in improving expectations and acceptability of MMT. Copyright © 2016 Elsevier Ireland Ltd. All rights reserved.

Thirty-two cases of canine cutaneous histiocytosis were retrospectively evaluated. Median age at onset was 4 years. Lesions included nodules and plaques affecting the head/face, trunk and limbs, and erythema, swelling and depigmentation of the nasal planum/nares. Systemic involvement was not ruled out in all cases. All dogs had complete resolution of dermatological lesions after initial treatment (median 45 days). Initial treatment included prednisone +/- antibiotics (12 of 32 dogs), prednisone and tetracycline/niacinamide (four of 32), prednisone and azathioprine (three of 32), tetracycline/niacinamide +/- vitamin E/essential fatty acids (six of 32), antibiotics +/- antihistamines (three of 32), cyclosporine and ketoconazole (one of 32), topical therapy (two of 32), and no treatment (one of 32). Seventeen dogs received maintenance therapy which consisted of tetracycline/niacinamide +/- vitamin E/essential fatty acids (12 of 17), cyclosporine/ketoconazole (two to three times a week) (two of 17), azathioprine daily (one of 17), prednisone/azathioprine (two times a week) (one of 17), and prednisone daily (one of 17). Median follow up was 25 months. Nine dogs had a recurrence of cutaneous histiocytosis (median days to recurrence 130 days), with seven of nine having more than one recurrence. At study completion, six dogs were deceased (no lesions at the time of death) and 26 of 32 were alive with no lesions. Ten of 26 dogs were on maintenance treatment (eight tetracycline/niacinamide, one azathioprine, one vitamin E). Previous dermatological disease and season had no detectable influence on recurrence. Recurrence was significantly more likely in dogs with nasal planum/nares lesions than dogs without these lesions. Tetracycline/niacinamide was an effective treatment option for dogs in this study population.

Incarceration provides a unique opportunity to initiate MMT for those who need it, however, optimal scale-up efforts must be systemic and address modifiable factors like improving attitudes toward and motivation for MMT. Informed or shared decision-making tools may be useful in improving expectations and acceptability of MMT. PMID:27207155

Improvements in Pneumatosis Cystoides Intestinalis and Hepatic Portal Venous Gas with Conservative Therapy in a Patient on Maintenance Dialysis.

A 77-year-old man on maintenance dialysis developed hypotension, nausea and abdominal pain one hour after beginning to undergo hemodialysis. Abdominal computed tomography (CT) showed gas shadows in the intrahepatic portal vein and the small intestinal wall, but no signs indicating intestinal necrosis. Three days later, the gas shadows on abdominal CT disappeared by conservative therapy. In cases with both pneumatosis cystoides intestinalis and hepatic portal venous gas, intestinal necrosis should therefore be suspected and surgical therapy should also be considered, particularly in hemodialysis patients with a risk of intestinal ischemia. However, conservative therapy may be an option in cases with no intestinal necrosis.

Obsessive-compulsive disorder (OCD) is defined as the most commonly seen anxiety disorder accompanying the bipolar disorder, and this concomitance causes the difficulties in the therapy. Although electroconvulsive therapy (ECT) is efficient in both manic and depressive episodes of the bipolar disorder, it is considered as a therapeutic option in cases of OCD with depression comorbidity. In this article, we aimed to present a case in which depressive episode of bipolar disorder and OCD comorbidity were present; both depressive and OCD symptoms were resolved using ECT. Symptoms of both diseases recurred after the discontinuation of ECT, and well-being sustained with maintenance ECT.

Development of a vancomycin dosing approach for critically ill patients receiving hybrid hemodialysis using Monte Carlo simulation.

2018-01-01

Prolonged intermittent renal replacement therapy is an increasingly popular treatment for acute kidney injury in critically ill patients that runs at different flow rates and durations than conventional hemodialysis or continuous renal replacement therapies. Pharmacokinetic studies conducted in patients receiving prolonged intermittent renal replacement therapy are scarce; consequently, clinicians are challenged to dose antibiotics effectively. The purpose of this study was to develop vancomycin dosing recommendations for patients receiving prolonged intermittent renal replacement therapy. Monte Carlo simulations were performed in thousands of virtual patients derived from previously published demographic, pharmacokinetic, and dialytic information derived from critically ill patients receiving vancomycin and other forms of renal replacement therapy. We conducted "in silico" vancomycin pharmacokinetic/pharmacodynamics analyses in these patients receiving prolonged intermittent renal replacement therapy to determine what vancomycin dose would achieve vancomycin 24-h area under the curve (AUC 24h ) of 400-700 mg·h/L, a target associated with positive clinical outcomes. Nine different vancomycin dosing regimens were tested using four different, commonly used prolonged intermittent renal replacement therapy modalities. A dosing nomogram based on serum concentration data achieved after the third dose was developed to individualize vancomycin therapy. An initial vancomycin dose of 15 or 20 mg/kg immediately followed by 15 mg/kg after subsequent prolonged intermittent renal replacement therapy treatments achieved AUC 24h of ≥400 mg·h/L for ≥90% of patients regardless of prolonged intermittent renal replacement therapy duration, modality, or time of vancomycin dose relative to prolonged intermittent renal replacement therapy. Many patients experienced AUC 24h of ≥700 mg·h/L, but once the dosing nomogram was applied to serum concentrations obtained after the third vancomycin dose, 67%-88% of patients achieved AUC 24h of 400-700 mg·h/L. An initial loading dose of 15-20 mg/kg followed by a maintenance regimen of 15 mg/kg after every prolonged intermittent renal replacement therapy session coupled with serum concentration monitoring should be used to individualize vancomycin dosing. These predictions need clinical verification.

Background Nephropathy is an important feature of classical Fabry disease, which results in alpha-galactosidase A deficiency and cellular globotriaosylceramide accumulation. We report the safety and efficacy of antiproteinuric therapy with ACE inhibitors or angiotensin II receptor blockers (ARBs) in a study of classical Fabry patients receiving recombinant agalsidase-beta therapy. Methods and design The goal was maintenance of urine protein to creatinine ratio (UPCR) <0.5 g/g or a 50% reduction in baseline UPCR for 24 patients at eight study sites. The change in estimated glomerular filtration rate (eGFR) was assessed over 21 months of treatment. Results 18 out of 24 patients achieved the UPCR goal with eGFR slopes that were significantly better than six patients who did not achieve the UPCR goal (−3.6 (−4.8 to −1.1) versus −7.0 (−9.0 to −5.6) mL/min/1.73 m2/year, respectively, p=0.018). Despite achieving the UPCR goal, 67% (12/18 patients) still progressed with an eGFR slope <−2 mL/min/1.73 m2/year. Regression analysis showed that increased age at initiation of agalsidase-beta therapy was significantly associated with worsened kidney outcome. Hypotension and hyperkalaemia occurred in seven and eight patients, respectively, which required modification of antiproteinuric therapy but was not associated with serious adverse events. Conclusions This study documents the effectiveness of agalsidase-beta (1 mg/kg/2 weeks) and antiproteinuric therapy with ACE inhibitors and/or ARB in patients with severe Fabry nephropathy. Patients had preservation of kidney function if agalsidase-beta treatment was initiated at a younger age, and UPCR maintained at or below 0.5 g/g with antiproteinuric therapy.

Combined Abuse of Clonidine and Amitriptyline in a Patient on Buprenorphine Maintenance Treatment

PubMed Central

Dittmer, Trent; Sigman, Erika J.; Clemons, Holly; Johnson, J. Aaron

2014-01-01

Buprenorphine/naloxone maintenance therapy is often prescribed in primary care to treat opioid dependence. Previous reports have described concomitant abuse of opioids and clonidine. In this case, a primary care patient on buprenorphine/naloxone maintenance therapy demonstrating altered mental status, hallucinations, falls, and rebound hypertension was found to be concomitantly abusing clonidine and amitryptyline, which share metabolic pathways with buprenorphine. Clinicians should be aware of patients' combining amitryptyline, clonidine, and gabapentin with buprenorphine to achieve a mood altering state, avoid co-prescribing them if possible, and maintain communication with pharmacies and other providers when they are prescribed.

Maintenance Fluid Therapy: Isotonic Versus Hypotonic Solutions.

PubMed

Hansen, Bernie; Vigani, Alessio

2017-03-01

The goal of maintenance fluid therapy in small animals is to replace normal ongoing losses of water and salts when oral intake is withheld. Hospitalized dogs and cats may have multiple stimuli for antidiuretic hormone release that disrupt normal osmoregulation and predispose to water retention. Severe illness promotes retention of both sodium and water as edema. Commercially available fluids have electrolyte concentrations that are very different from dietary maintenance requirements, and potential consequences include development of hypoosmolality, edema, or both when excesses of water or sodium are administered. Suggestions for tailoring fluid administration toward specific goals are provided. Copyright © 2016 Elsevier Inc. All rights reserved.

The safe implementation of a prison-based methadone maintenance programme: 7 year time-series analysis of primary care prescribing data

PubMed Central

2014-01-01

Background Internationally there is policy support for the introduction of methadone maintenance programmes into prison settings. Increasingly GPs are encouraged to undertake this work although concerns remain regarding the safety of such programmes. This study sought to evaluate the impact and safety of the introduction of a general practitioner with a special interest (GPsi) in substance misuse led methadone prescribing service into a UK prison between 2003 and 2010. Methods Time series analysis of secondary prescribing data pertaining to opiate maintenance therapies, opiate detoxification therapies and opiate related deaths for the time period 2003 to 2010. Results Results show that following introduction of a GPsi in substance misuse there was a statistically significant increase in both methadone maintenance and detoxification treatments. Over time the rate of methadone maintenance prescribing plateaued with a corresponding decrease in the rate of methadone detoxification prescribing. There were no methadone related deaths in prison over the study period. Conclusion The phased introduction of opiate replacement therapies into a busy remand prison did not result in any deaths within the prison for which opiate replacement was identified as the cause. GPsi led opiate prescribing programmes can be introduced safely into secure environments. PMID:24712316

2010-06-01

In patients with coronary artery stents, the cost of clopidogrel has been cited as a factor in the premature discontinuation of therapy. Thus, the introduction of lower-cost generic clopidogrel may increase patient compliance. However, platelet inhibition by generic clopidogrel has not been compared to the original clopidogrel formulation in patients with coronary artery stents. We prospectively enrolled 20 patients receiving chronic therapy with the original clopidogrel bisulfate (Plavix). After assessing patient compliance with Plavix, maintenance therapy was switched to generic clopidogrel bisulfate (Plavitor). Platelet reactivity was assessed at baseline and 30-day after the switch using conventional aggregometry and the VerifyNow P2Y12 assay. All patients completed maintenance therapy with Plavitor. Before and after switching therapy maximal (36.5 +/- 7.9% vs. 39.8 +/- 16.2%, p = 0.280) and late platelet aggregation (23.5 +/- 10.9% vs. 29.1 +/- 18.3%, p = 0.156) with 5 micromol/L adenosine diphosphate (ADP) stimulus did not differ. Likewise, 20 micromol/L ADP-induced platelet aggregation and P2Y12 reaction unit in patients on Plavitor therapy was comparable to that in patients on Plavix therapy. However, Bland-Altman analysis showed wide limits of agreement between measured platelet reactivity on Plavix vs. Plavitor therapies. Among patients on Plavix maintenance therapy with coronary stents, replacement with Plavitor shows a comparable inhibition of ADP-induced platelet aggregation. However, due to poor inter-therapy agreement, between two regimens, physicians may be cautious when introducing generic clopidogrel bisulfate.

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.

The safety of continued ustekinumab (UST) therapy during pregnancy remains unclear in patients with Crohn's disease (CD). There are no meta-analysis reports of exposure to UST during pregnancy. The objective was to describe a case of a pregnant patient with CD who was successfully treated with UST maintenance therapy throughout the pregnancy and delivered a baby boy without any congenital malformations, neurological abnormalities or birth defects. A 37-year-old patient with CD treated with UST became pregnant. She had been receiving UST for 8 months at the time. After discussion with the patient and the obstetric team, the UST therapy was continued. The result of treatment was an uneventful pregnancy with delivery, at term, of a healthy boy and the maintenance of clinical, biological and endoscopic remission of CD during and after pregnancy. To our knowledge, this is the first reported use of continued UST therapy for CD throughout a pregnancy. The result of treatment was an uncomplicated pregnancy with the mother giving birth to a healthy boy at term and the maintenance of clinical biological and endoscopic remission of CD during and after pregnancy. © 2016 John Wiley & Sons Ltd.

[Medical therapy of inflammatory bowel diseases: ulcerative colitis].

PubMed

Lakatos, László; Lakatos, Péter László

2007-06-24

There are fewer significant changes in the medical therapy of ulcerative colitis (UC) compared to Crohn's disease. The most important factors that determine therapy are disease extent and severity. 5-aminosalicylates (5-ASA) constitute the treatment of choice in mild-to-moderate UC. The efficacy of new compounds (e.g. mesalazine) is only mildly improved compared to sulphasalazine; however, their use has become more frequent due to a more favorable side effects profile. Topical medication is more effective in proctitis and distal colitis, and the combination of topical and orally-administered drugs is superior to oral therapy alone also in extensive disease. Thus, this latter regimen should be considered for cases where the escalation of treatment is required. Systemic steroids still represent the first line therapy in acute, severe UC, while in patients who do not respond to steroids, cyclosporine and infliximab should be considered as a second line therapy and as alternatives for colectomy. Maintenance treatment is indicated in all UC cases. 5-ASA compounds are suggested as first line maintenance therapy with the optimal dose still being under investigation. Topical compounds are effective also for maintenance in distal colitis or proctitis, if accepted by the patients. Immunosuppressives, especially azathioprine, should be considered in chronically active, steroid dependent or resistant patients. According to recent publications, azathioprine is almost equally effective in UC and CD. The question of chemoprevention is important during maintenance. There are increasing data supporting the notion that aminosalicylates may lower the risk for UC-associated colorectal cancer. The most important changes in the management of UC are the more frequent use of topical aminosalicylates and azathioprine, the availability of infliximab in severe UC, and increasing use of aminosalicylates for chemoprevention of colorectal carcinoma. Furthermore, adequate attention is needed to better organize the patient-doctor relationship and for greater adherence to medical therapy.

Combination therapy with infliximab and immunomodulators is superior to monotherapy, resulting in better outcomes and higher trough levels of infliximab. The role of concurrent immunomodulatory therapy on adalimumab trough levels has not been adequately investigated. We evaluated the impact of concomitant immunomodulation on adalimumab trough levels in patients on scheduled maintenance therapy. We conducted a prospective observational, cross-sectional study of all inflammatory bowel disease patients on maintenance therapy who had adalimumab trough levels measured between January 2013 and January 2016. Drug level and anti-drug antibody measurements were performed on sera using a solid phase assay. Pairwise comparison of means was used to compare trough levels in patients with and without concomitant immune modulator therapy. In total, 79 patients were included. Twenty-three patients (29.1%) were on weekly dosing whereas 56 (70.9%) were on alternate weeks. Median adalimumab trough levels were comparable in patients with and without clinical remission (6.8 μg/ml (IQR 5.6-8.1) versus 6.7 μg/ml (IQR 3.9-8.1), respectively. Patients with an elevated faecal calprotectin >250 μg/g had lower adalimumab trough levels (median 6.7, IQR 3.9-8) compared to patients with faecal calprotectin <250 μg/g (median 7.7, IQR 6.1-8.1) though this did not achieve statistical significance (p = .062). Median adalimumab trough levels among patients on concurrent immunomodulators was 7.2 μg/ml (IQR 5.7-8.1) compared to those not on concurrent immunomodulator, 6.1 μg/ml (IQR 2.7-7.7, p = .0297). Adalimumab trough levels were significantly higher in patients on concurrent immunomodulators during maintenance therapy. There was a trend towards a lower adalimumab trough level in patients with elevated calprotectin.

Chemotherapy remains the first-line therapy for aggressive lymphomas. However, 20-30% of patients with non-Hodgkin lymphoma (NHL) and 15% with Hodgkin lymphoma (HL) recur after initial therapy. We want to explore the role of high-dose chemotherapy (HDT) and autologous stem cell transplant (ASCT) for these patients. There is some utility of upfront consolidation for-high risk/high-grade B-cell lymphoma, mantle cell lymphoma, and T-cell lymphoma, but there is no role of similar intervention for HL. New conditioning regimens are being investigated which have demonstrated an improved safety profile without compromising the myeloablative efficiency for relapsed or refractory HL. Salvage chemotherapy followed by HDT and rescue autologous stem cell transplant remains the standard of care for relapsed/refractory lymphoma. The role of novel agents to improve disease-related parameters remains to be elucidated in frontline induction, disease salvage, and high-dose consolidation or in the maintenance setting.

Peritoneal Dialysis in Austere Environments: An Emergent Approach to Renal Failure Management

2018-01-01

Peritoneal dialysis (PD) is a means of renal replacement therapy (RRT) that can be performed in remote settings with limited resources, including regions that lack electrical power. PD is a mainstay of end-stage renal disease (ESRD) therapy worldwide, and the ease of initiation and maintenance has enabled it to flourish in both resource-limited and resource-abundant settings. In natural disaster scenarios, military conflicts, and other austere areas, PD may be the only available life-saving measure for acute kidney injury (AKI) or ESRD. PD in austere environments is not without challenges, including catheter placement, availability of dialysate, and medical complications related to the procedure itself. However, when hemodialysis is unavailable, PD can be performed using generally available medical supplies including sterile tubing and intravenous fluids. Amidst the ever-increasing global burden of ESRD and AKI, the ability to perform PD is essential for many medical facilities. PMID:29760854

2017-01-01

Background HIV-1 enters the CNS within two weeks after peripheral infection and results in chronic neuroinflammation that leads to HIV associated neurocognitive disorders (HAND) in more than 50% of infected people. HIV enters the CNS by transmigration of infected monocytes across the blood brain barrier. Intravenous drug abuse is a major risk factor for HIV-1 infection, and opioids have been shown to alter the progression and severity of HAND. Methadone and buprenorphine are opioid derivates that are used as opioid maintenance therapies. They are commonly used to treat opioid dependency in HIV infected substance abusers, but their effects on monocyte migration relevant to the development of cognitive impairment are not well characterized. Conclusion Here, we will discuss the effects of opioids and opioid maintenance therapies on the inflammatory functions of monocytes and macrophages that are related to the development of neuroinflammation in the context of HIV infection.

Bevacizumab is a monoclonal antibody targeting the vascular endothelial growth factor receptor and a key drug for advanced non-small cell lung cancer. There are few reports describing bevacizumab-induced chronic interstitial pneumonia. A 62-year-old man with advanced non-small cell lung cancer was admitted to our hospital with dyspnea. He previously received four courses of carboplatin plus paclitaxel with bevacizumab combination therapy and thereafter received four courses of maintenance bevacizumab monotherapy. A chest-computed tomography scan on admission revealed diffuse ground glass opacity. He had not received any other drugs and did not have pneumonia. Thus, he was diagnosed with bevacizumab-induced chronic interstitial pneumonia and was treated with a high dose of corticosteroids. After steroid treatment, his dyspnea and radiological findings improved. This case report is the first description of bevacizumab-induced chronic interstitial pneumonia during maintenance therapy in a patient with non-small cell lung cancer.

Ulcerative proctitis: a review of pharmacotherapy and management.

Ulcerative proctitis (UP) is a common presentation of ulcerative colitis (UC). To summarize available literature on up-to-date management and pharmacotherapy of UP patients. Extensive Medline/Embase literature search was performed to identify relevant articles. Topical medication with rectally administered 5-aminosalicylic acid (5-ASA)/corticosteroid suppositories or enemas is effective treatment for most UP patients. Locally administered 5-ASA is more efficacious than oral compounds. The combination of topical 5-ASA and oral 5-ASA or topical steroids should be considered for escalation of treatment. Maintenance treatment is indicated in all UC cases. 5-ASA suppositories are suggested as first-line maintenance therapy if accepted by patients, although oral 5-ASA as maintenance therapy might prevent proximal extension of the disease. After re-assessment, chronically active patients refractory or intolerant to 5-ASAs and corticosteroids may require immunomodulators or biological therapy. Exceptional cases may require a proctocolectomy.

Drug Addiction Stigma in the Context of Methadone Maintenance Therapy: An Investigation into Understudied Sources of Stigma.

2013-02-01

Experiences of stigma from others among people with a history of drug addiction are understudied in comparison to the strength of stigma associated with drug addiction. Work that has studied these experiences has primarily focused on stigma experienced from healthcare workers specifically even though stigma is often experienced from other sources as well. Because stigma has important implications for the mental health and recovery efforts of people in treatment, it is critical to better understand these experiences of stigma. Therefore, we characterize drug addiction stigma from multiple sources using qualitative methodology to advance understandings of how drug addiction stigma is experienced among methadone maintenance therapy patients and from whom. Results demonstrate that methadone maintenance therapy patients experience prejudice, stereotypes, and discrimination from friends and family, coworkers and employers, healthcare workers, and others. Discussion highlights similarities and differences in stigma experienced from these sources.

In the last decade dramatic improvements have been obtained in the treatment of metastatic colorectal cancer. Thanks to the introduction in the clinical practice of new drugs such as Irinotecan and Oxaliplatin, and modern biological drugs such as Bevacizumab and Cetuximab, the response rate, progression-free and overall survival are about 50-60%, 9-11 and 20-24 months respectively. Despite this progress, many questions remain unsolved especially those related to the optimal duration of treatment and the role of maintenance therapy. To treat until progression (or unacceptable toxicity) is the classical way but in the common clinical practice is frequent to perform an induction therapy (until the maximum response is obtained) followed by a complete stop and restart on progression, or by a maintenance without the drug/s responsible of the major cumulative toxicities. The following report focus on the role of different strategies respect to the classic "treatment until progression". Copyright © 2010 Elsevier Ltd. All rights reserved.

Multiple treatments are available for osteoporosis; however, little is known about treatment change patterns and associated factors. Osteoporosis treatment change patterns, discontinuation and factors associated with treatment change in members of a large national health plan were examined. A retrospective cohort study was conducted in 7315 commercial and 34 146 Medicare Advantage Prescription Drug (MAPD) members newly initiated on an osteoporosis medication between 2006 and 2008. Osteoporosis treatment change, discontinuation and re-initiation patterns were assessed. Multivariate logistic regression was used to examine factors associated with treatment change. Commercial and MAPD members were assessed separately because of differences in demographics and insurance benefits. Approximately 12% of members had a change in index therapy within 12 months. Almost 60% of members discontinued the index medication at least once, based on a 90-day refill gap. Over 40% of members discontinued all osteoporosis medications by the end of 12 months post-index. Among MAPD and commercial members, women and those with risedronate, ibandronate or calcitonin at index, index therapy in 2008 and an osteoporosis diagnosis were more likely to have a treatment change while members with health plans other than health maintenance organizations and generic alendronate at index were less likely to have a treatment change. Osteoporosis treatment change occurred in approximately 12% of members, while a greater proportion of members discontinued treatment completely within 12 months. Member characteristics may be used to predict therapy change for evaluation and quality initiatives within a health plan. © 2011 Blackwell Publishing Ltd.

Patients undergoing maintenance hemodialysis develop both structural and functional cardiovascular abnormalities. Despite improvement of dialysis technology, cardiovascular mortality of this population remains high. The pathophysiological mechanisms of these changes are complex and not well understood. It has been postulated that several non-traditional, uremic-related risk factors, especially the long-term uremic state, which may affect the cardiovascular system. There are many cardiovascular changes that occur in chronic kidney disease including left ventricular hypertrophy, myocardial fibrosis, microvascular disease, accelerated atherosclerosis and arteriosclerosis. These structural and functional changes in patients receiving chronic dialysis make them more susceptible to myocardial ischemia. Hemodialysis itself may adversely affect the cardiovascular system due to non-physiologic fluid removal, leading to hemodynamic instability and initiation of systemic inflammation. In the past decade there has been growing awareness that pathophysiological mechanisms cause cardiovascular dysfunction in patients on chronic dialysis, and there are now pharmacological and non-pharmacological therapies that may improve the poor quality of life and high mortality rate that these patients experience.

MYC deregulation is common in human cancer. IG-MYC translocations that are modeled in Eμ-Myc mice occur in almost all cases of Burkitt lymphoma as well as in other B-cell lymphoproliferative disorders. Deregulated expression of MYC results in increased mTORC1 signaling. As tumors with mTORC1 activation are sensitive to mTORC1 inhibition, we used everolimus, a potent and specific mTORC1 inhibitor, to test the requirement for mTORC1 in the initiation and maintenance of Eμ-Myc lymphoma. Everolimus selectively cleared premalignant B-cells from the bone marrow and spleen, restored a normal pattern of B-cell differentiation and strongly protected against lymphoma development. Established Eμ-Myc lymphoma also regressed after everolimus therapy. Therapeutic response correlated with a cellular senescence phenotype and induction of p53 activity. Therefore mTORC1-dependent evasion of senescence is critical for cellular transformation and tumor maintenance by MYC in B-lymphocytes. PMID:23242809

Cancer stem cells (CSCs) or tumor-initiating cells (TICs) represent a small population of cancer cells with self-renewal and tumor-initiating properties. Unlike the bulk of tumor cells, CSCs or TICs are refractory to traditional therapy and are responsible for relapse or disease recurrence in cancer patients. Stem cells have distinct metabolic properties compared to differentiated cells, and metabolic rewiring contributes to self-renewal and stemness maintenance in CSCs. Recent advances in metabolomic detection, particularly in hyperspectral-stimulated raman scattering microscopy, have expanded our knowledge of the contribution of lipid metabolism to the generation and maintenance of CSCs. Alterations in lipid uptake, de novo lipogenesis, lipid droplets, lipid desaturation, and fatty acid oxidation are all clearly implicated in CSCs regulation. Alterations on lipid metabolism not only satisfies the energy demands and biomass production of CSCs, but also contributes to the activation of several important oncogenic signaling pathways, including Wnt/β-catenin and Hippo/YAP signaling. In this review, we summarize the current progress in this attractive field and describe some recent therapeutic agents specifically targeting CSCs based on their modulation of lipid metabolism. Increased reliance on lipid metabolism makes it a promising therapeutic strategy to eliminate CSCs. Targeting key players of fatty acids metabolism shows promising to anti-CSCs and tumor prevention effects.

Emerging evidence has emphasized the importance of cancer therapies targeting an abnormal metabolic state of tumor-initiating cells (TICs) in which they retain stem cell-like phenotypes and nicotinamide adenine dinucleotide (NAD + ) metabolism. However, the functional role of NAD + metabolism in regulating the characteristics of TICs is not known. In this study, we provide evidence that the mitochondrial NAD + levels affect the characteristics of glioma-driven SSEA1 + TICs, including clonogenic growth potential. An increase in the mitochondrial NAD + levels by the overexpression of the mitochondrial enzyme nicotinamide nucleotide transhydrogenase (NNT) significantly suppressed the sphere-forming ability and induced differentiation of TICs, suggesting a loss of the characteristics of TICs. In addition, increased SIRT3 activity and reduced lactate production, which are mainly observed in healthy and young cells, appeared following NNT-overexpressed TICs. Moreover, in vivo tumorigenic potential was substantially abolished by NNT overexpression. Conversely, the short interfering RNA-mediated knockdown of NNT facilitated the maintenance of TIC characteristics, as evidenced by the increased numbers of large tumor spheres and in vivo tumorigenic potential. Our results demonstrated that targeting the maintenance of healthy mitochondria with increased mitochondrial NAD + levels and SIRT3 activity could be a promising strategy for abolishing the development of TICs as a new therapeutic approach to treating aging-associated tumors.

Tumor necrosis factor (TNF) antagonists are commonly used to treat rheumatoid arthritis (RA). Differences in the dosage and mode of administration of these agents may result in differential rates of dosage adjustment and costs of care. This study compared dosing patterns and annual costs associated with the use of the subcutaneous TNF antagonists adalimumab and etanercept, and the intravenous TNF antagonist infliximab. A large managed care database (PharMetrics) was used to identify patients with RA who newly initiated TNF-antagonist therapy with adalimumab, etanercept, or infliximab on or after January 1, 2003, and had at least 6 months of continuous health plan enrollment before initiation of therapy and 12 months of continuous enrollment after initiation. The patients were followed over 12 months of enrollment. Annual pharmacy, inpatient, and outpatient costs were estimated based on plan reimbursements and were compared between cohorts. The average daily dosage (ADD) between prescription refills was used to compare the percentages of patients with greater-than-expected dosing (GTED), defined as 2 consecutive increases in ADD relative to the patient's established maintenance dosage. A total of 2382 patients (568 adalimumab, 1181 etanercept, 633 infliximab) were included in the analysis. Significantly more patients had GTED with infliximab compared with adalimumab and etanercept (32.1%, 8.5%, and 4.7%, respectively; both comparisons, P < 0.05). For patients with a dosage increase, the mean time to the first GTED was significantly shorter for infliximab compared with adalimu-mab and etanercept (154.5, 173.3, and 167.9 days; both, P < 0.05). The mean annual costs of anti-TNF therapy, adjusted for baseline differences, were significantly greater for infliximab compared with adalimumab and etanercept ($15,617, $12,200, and $12,146; both, P < 0.05). There were also significant differences between infliximab relative to adalimumab and etanercept in total RA-related medication costs ($16,280, $12,989, and $12,794; P < 0.05) and total pharmacy costs ($17,854, $14,805, and $14,398; P < 0.05). Patients initiating TNF-antagonist treatment for RA with infliximab incurred annual medication costs that were nearly 30% greater than costs in those initiating therapy with adalimumab or etanercept, in part because of the significantly greater rate of GTED in infliximab recipients.

Multiple myeloma (MM) despite the introduction to clinical practice of a new drugs in the last years, and still searching of new points of the handle for targeting treatment, remaining incurable disease. Even most intensive and most modern induction-consolidation regimens is not in the state to eradicate of the clone of myeloma, and even complete remission in immunofixation the most often after some time ends progression. Optimal way of maintenance treatment is still searching, which would be maximally effective near acceptable toxicity. Now hypothesis about possible successful maintenance therapy, which may prolong survival of MM patients became more actual in the face of the introduction to the studies with maintenance of a new drugs as: thalidomide, lenalidomide and bortesomib. The expectations on the essential progress to establish the optimal bortesomib-based regimen of the maintenance treatment in MM cause the results of the studies with its subcutaneous administration, which proved comparable efficacy with advantage in toxicity profile, especially neurological in comparison to classic intravenous way.

Electroconvulsive therapy (ECT) raises the seizure threshold. This physiological change may benefit patients with seizure disorders. Whereas ECT has recently been used to terminate medication-refractory status epilepticus, there is little current literature on its planned administration as a specific maintenance treatment for medication-refractory epilepsy. We used maintenance ECT to treat an 18-year-old man with a long-standing generalized tonic-clonic seizure disorder who had shown poor response to several antiepileptic drugs administered in combination with antiepileptic medication compliance confirmed through drug level monitoring. A total of 52 ECTs were administered across nearly 20 months at a mean frequency of once in nearly 12 days. From the very outset, ECT dramatically decreased the frequency of spontaneous seizures from approximately 6 to 24 per week at baseline to approximately 1 to 2 per week after ECT initiation. The efficacy of maintenance ECT in spontaneous seizure prophylaxis was greater when the ECT treatment interval was narrower. Improvement with ECT was associated with improved behavior and improved psychosocial functioning on clinical report. No cognitive or other adverse effects were reported or clinically ascertained. The ECT charge administered at the last 10 treatment sessions was 1434 millicoulombs. This is probably the highest electrical stimulus dose recorded in literature. Maintenance ECT may reduce the frequency of breakthrough seizures in patients with seizure disorder that is inadequately responsive to antiepileptic medication regimes. Very high ECT seizure thresholds may be observed when many antiepileptic drugs are concurrently administered in high doses.

In view of increasing controversy regarding the role of double hemibody irradiation (DHBI) in the treatment of multiple myeloma, we have analysed the use of this technique at our institution over a 6-year period. Fifty-five patients with multiple myeloma were treated with both upper and lower hemibody irradiation between January 1985 and January 1991; 42 had relapsed post-plateau and 13 were chemoresistant to initial therapy. Fifteen patients received alpha IFN-2b maintenance therapy post-DHBI, at a dose of 3 Mu three times per week, as part of a randomized trial. Ninety-five per cent of patients experienced symptomatic improvement in bone pain post-DHBI, 21% of whom discontinued opiate analgesics altogether; 63% had a minor biochemical response and 38% had a partial biochemical response. The overall survival (OS) and progression free survivals (PFS) in all patients were 11 months and 8 months respectively. No significant difference was noted in either OS or PFS, according to whether patients were chemoresistant or had relapsed post-plateau. alpha IFN did not appear to prolong survival (OS or PFS) post-DHBI. Cytopenia was a significant problem, such that only 60% of patients had counts adequate enough to be eligible for alpha IFN. We conclude that DHBI is an effective treatment in patients with relapsed multiple myeloma and in those who are chemoresistant to initial therapy.(ABSTRACT TRUNCATED AT 250 WORDS)

Immunotherapy is the titrated exposure of allergens to induce immunologic tolerance and offers long-term immune modification. Traditional subcutaneous immunotherapy (SCIT) has resulted in several deaths and raised safety concerns. Sublingual immunotherapy (SLIT) is an alternative administration route for allergen-specific immunotherapy. Compared to SCIT, SLIT has a shorter escalation phase, equal or greater efficacy for rhinitis, and an improved safety profile. The purpose of this study was to evaluate quality of life measures in a preliminary patient sample initiating SLIT at our institution. Patients with appropriate allergen reactivity were given the option to pursue immunotherapy by traditional SCIT or by SLIT techniques. Patients choosing SLIT completed the mini-Rhinoconjunctivitis Quality of Life Questionnaire (m-RQLQ), a 14-item Likert-type questionnaire, at baseline and during maintenance therapy. Patients typically reached maintenance dosing in less than 5 weeks. Paired m-RQLQ data were available for 15 patients after antigen titration. Initial m-RQLQ results indicate statistically significant (P < .05) improvement on 12 of 14 domains, including impact on regular and recreational activities, sleep, nose rubbing and nose blowing, stuffy nose and runny nose, itchy eyes, sore eyes, watery eyes, thirst, and tiredness. In addition, total m-RQLQ score showed statistically significant improvement (P = .001). No serious adverse events occurred with the initiation of SLIT. These results indicate that SLIT is effective in controlling allergic symptoms and is safe in an introductory patient sample. Double-blind placebo-controlled trials are needed to confirm our preliminary results.

Patients with acute leukemias of undifferentiated lineage (AUL) generally have guarded prognosis. Here, we describe the first reported pediatric patient with AUL refractory to high-dose chemotherapy who achieved clinical remission with ALL maintenance therapy and 5-azacitidine. His induction remission was followed by consolidation with reduced toxicity haploidentical hematopoietic stem cell transplant (HSCT). At 9 months post-HSCT, the patient is alive and in remission. This combination therapy of remission induction with ALL maintenance therapy and 5-azacitidine and consolidation with reduced toxicity haploidentical HSCT is novel and promising for patients who lack conventional donors and are not candidates for myeloablative therapy. © 2016 Wiley Periodicals, Inc.

Obesity is a significant public health problem. Although various lifestyle approaches are effective for inducing significant weight loss, few effective behavioral weight maintenance strategies have been identified. It has been proposed that behavior maintenance is a distinct state that involves different psychological processes and behavioral skills than initial behavior change. Previously, we created a conceptual model that distinguishes behavior initiation from maintenance. This model was used to generate Maintenance After Initiation of Nutrition TrAINing (MAINTAIN), an intervention to enhance weight loss maintenance following initiation. The effectiveness of MAINTAIN is being evaluated in an ongoing trial, the rationale and procedures of which are reported herein. Veterans aged ≤ 75 with body mass index ≥ 30 kg/m(2) participate in a 16-week, group-based weight loss program. Participants who lose ≥ 4 kg by the end of 16 weeks (target n = 230) are randomized 1:1 to receive (a) usual care for 56 weeks or (b) MAINTAIN, a theoretically-informed weight loss maintenance intervention for 40 weeks, followed by 16 weeks of no intervention contact. MAINTAIN involves 3 in-person group visits that transition to 8 individualized telephone calls with decreasing contact frequency. MAINTAIN focuses on satisfaction with outcomes, weight self-monitoring, relapse prevention, and social support. We hypothesize that, compared to usual care, MAINTAIN will result in at least 3.5 kg less regain and better relative levels of caloric intake and physical activity over 56 weeks, and that it will be cost-effective. If effective, MAINTAIN could serve as a model for redesigning existing weight loss programs. NCT01357551. Published by Elsevier Inc.

The use of inhaled corticosteroids (ICSs) plays a key role in the treatment of asthmatic patients, and international guidelines have designated ICSs as an early maintenance therapy in controlling asthma symptoms. When asthmatic patients remain symptomatic on ICSs, one common option is to add a long-acting beta2 agonist (LABA) to the maintenance treatment. Fixed combination inhalers that contain both an ICS and a LABA have been popular for both chronic obstructive pulmonary disease (COPD) and asthma. Historically, these inhalers have been dosed twice daily. However, currently, there is a once-daily combination therapy with the ICS fluticasone furoate (FF) and the LABA vilanterol trifenatate (VI) with indications for use in both COPD and asthma. This dry powder inhaler (DPI) comes in two doses of FF (100 or 200 μg) both combined with VI (25 μg). This article reviews the clinical trial data for FF, VI and FF/VI combination inhalers and documents the efficacy and safety of once-daily inhaled maintenance therapy by DPI in asthmatic patients.

We describe a case of a patient with CD34+, TdT+, CD13-, CD33-, MPO- undifferentiated acute leukemia who refused chemotherapy and who achieved complete hematological remission 14 months after the diagnosis, during a short course of granulocyte-colony stimulating factor (G-CSF) for neutropenia and life threatening infection. Relapse occurred approximately one year later and G-CSF was reintroduced, being maintained for 4 months, at a dose and frequency adapted to maintain normal blood counts, a complete hematological remission being achieved again. Five months after withdrawing the G-CSF therapy a second relapse was observed; G-CSF was tried again with success, resulting in a very good hematological response that was sustained by G-CSF maintenance therapy. One year latter there was the need of increasing the doses of G-CSF in order to obtain the same hematological effect, at same time blast cells acquired a more mature CD34+, TdT-, CD13+, CD33-, MPO+ myeloid phenotype. Finally, the patient developed progressive neutropenia, anemia, thrombocytopenia and acute leukemia in spite of G-CSF therapy, dying 64 months after initial diagnosis (50 months after starting G-CSF therapy) with overt G-CSF resistant acute myeloblastic leukemia (AML), after failure of conventional induction chemotherapy.

Fluid therapy for acute bacterial meningitis.

Acute bacterial meningitis remains a disease with high mortality and morbidity rates. However, with prompt and adequate antimicrobial and supportive treatment, the chances for survival have improved, especially among infants and children. Careful management of fluid and electrolyte balance is an important supportive therapy. Both over- and under-hydration are associated with adverse outcomes. This is the latest update of a review first published in 2005 and updated in 2008 and 2014. To evaluate treatment of acute bacterial meningitis with differing volumes of initial fluid administration (up to 72 hours after first presentation) and the effects on death and neurological sequelae. For this 2016 update we searched the following databases up to March 2016: the Cochrane Acute Respiratory Infections Group's Specialised Register, CENTRAL, MEDLINE, CINAHL, Global Health, and Web of Science. Randomised controlled trials (RCTs) of differing volumes of fluid given in the initial management of bacterial meningitis were eligible for inclusion. All four of the original review authors extracted data and assessed trials for quality in the first publication of this review (one author, ROW, has passed away since the original review; see Acknowledgements). The current authors combined data for meta-analysis using risk ratios (RRs) for dichotomous data or mean difference (MD) for continuous data. We used a fixed-effect statistical model. We assessed the overall quality of evidence using the GRADE approach. We included three trials with a total of 420 children; there were no trials in adult populations. The largest of the three trials was conducted in settings with high mortality rates and was judged to have low risk of bias for all domains, except performance bias which was high risk. The other two smaller trials were not of high quality.The meta-analysis found no significant difference between the maintenance-fluid and restricted-fluid groups in number of deaths (RR 0.82, 95% confidence interval (CI) 0.53 to 1.27; 407 participants; low quality of evidence) or acute severe neurological sequelae (RR 0.67, 95% CI 0.41 to 1.08; 407 participants; low quality of evidence). However, when neurological sequelae were defined further, there was a statistically significant difference in favour of the maintenance-fluid group for spasticity (RR 0.50, 95% CI 0.27 to 0.93; 357 participants); and seizures at both 72 hours (RR 0.59, 95% CI 0.42 to 0.83; 357 participants) and 14 days (RR 0.19, 95% CI 0.04 to 0.88; 357 participants). There was very low quality of evidence favouring maintenance fluid over restrictive fluid for chronic severe neurological sequelae at three months follow-up (RR 0.42, 95% CI 0.20 to 0.89; 351 participants). The quality of evidence regarding fluid therapy in children with acute bacterial meningitis is low to very low and more RCTs need to be conducted. There is insufficient evidence to guide practice as to whether maintenance fluids should be chosen over restricted fluids in the treatment of acute bacterial meningitis.

Defining the genetic drivers of cancer progression is a key in understanding disease biology and developing effective targeted therapies. Chromosome rearrangements are a common feature of human malignancies, but whether they represent bona fide cancer drivers and therapeutically actionable targets, requires functional testing. Here, we describe the generation of transgenic, inducible CRISPR-based mouse systems to engineer and study recurrent colon cancer-associated EIF3E-RSPO2 and PTPRK-RSPO3 chromosome rearrangements in vivo. We show that both Rspo2 and Rspo3 fusion events are sufficient to initiate hyperplasia and tumour development in vivo, without additional cooperating genetic events. Rspo-fusion tumours are entirely Wnt-dependent, as treatment with an inhibitor of Wnt secretion, LGK974, drives rapid tumour clearance from the intestinal mucosa without effects on normal intestinal crypts. Altogether, our study provides direct evidence that endogenous Rspo2 and Rspo3 chromosome rearrangements can initiate and maintain tumour development, and indicate a viable therapeutic window for LGK974 treatment of RSPO-fusion cancers.

Aims To understand how the general public views the quality of life effects of opioid misuse and opioid use disorder on an individual and his/her spouse, measured in terms used in economic evaluations. Design Cross-sectional internet survey of a US-population-representative respondent panel conducted December 2013-January 2014. Setting USA. Participants 2,054 randomly-selected adults; 51% male (before weighting). Measurements Mean (95% CI) and median health “utility” for 6 opioid misuse and treatment outcomes: active injection misuse; active prescription misuse; methadone maintenance therapy at initiation, and when stabilized in treatment; and buprenorphine therapy at initiation, and when stabilized. Utility is a numerical representation of health-related quality of life used in economic evaluations to “adjust” estimated survival to include peoples' preferences for health states. Utilities are determined by surveying the general population to estimate the value they assign to particular health states—on a scale where 0=the value of being dead, and 1.0=the value of being in perfect health. Spouse spillover utility is assigned to a spouse of an individual who is in a particular health state. Findings Mean individual utility ranged from 0.574 (95%CI: 0.538, 0.611) for active injection opioid misuse to 0.766 for stabilized buprenorphine therapy (95%CI: 0.738, 0.795), with other states in between. Female respondents assigned higher utility to the active prescription misuse and buprenorphine therapy at initiation states than did males (p<0.05); all other states did not differ by respondent gender. Mean spousal utilities were significantly lower than 1.0 but mostly higher than individual utility, and were similar between male and female respondents. Conclusions In the opinion of the US public, injection opioid misuse results in worse health-related quality of life than prescription misuse, and methadone therapy results in worse health-related quality of life than buprenorphine therapy. Spouses are negatively affected by their partner's opioid misuse and early treatment. PMID:26498740

The race against the "septic shark"

PubMed Central

2015-01-01

Great white sharks are responsible for about 10 cases of death annually worldwide, as compared with millions of deaths caused by sepsis. However, the basic principles of avoiding shark attacks and fighting sepsis seem to be similar: avoidance, attention, and speed, if necessary. The present review discusses the current status of the systemic inflammatory response syndrome (SIRS) criteria, which are actually content for discussion because of their low specificity. Current data suggest that one in eight patients with severe sepsis does not fulfill the SIRS criteria and is consequently missed, and therefore the calls for new definitions of sepsis are getting louder. Furthermore, the need for early treatment of sepsis and fast admission to an intensive care unit (ICU) with experienced stuff is reviewed as well as the early and appropriate initiation of therapy, namely antibiotic and volume therapy. A key feature is the analysis of the studies from the so-called "Sepsis Trilogy" (ProCESS, ARISE, and ProMiSe studies), with a focus on the status of early goal-directed therapy (EGDT). The authors of the "Sepsis Trilogy" concluded that there is no benefit regarding survival in septic patients by using EGDT as compared with standard therapy. However, the low mortality of the control groups within the "Sepsis Trilogy" studies as compared with the Rivers et al. study from 2001 leads to the conclusion that there has been an improvement in the therapy of septic patients, most probably due to the early initiation of therapy as a kind of "standard" in sepsis therapy. Finally, the phenomenon of a "large trial disease" is discussed, exemplary in a trial which investigated the maintenance of the "right" mean arterial pressure in sepsis patients. Even if the result of a large randomized trial might be that there is no difference between two study groups, the real exercise is to identify the patient collectives who might benefit or experience harm due to an intervention. In summary, as compared with swimming in dangerous waters, high attention is needed in handling septic patients. Once an attack has occurred, speed is of utmost importance (i.e., initiation of therapy and admission to the ICU) because it appears logical that time is critical in septic patients This may have resulted in the implementation of early (goal-directed) treatment as a "standard" in the treatment of sepsis with significant improvement in survival.

Maintenance strategy has been used to improve survival in non-small cell lung cancer (NSCLC). We investigated whether switch maintenance therapy with vinorelbine improved progression free survival (PFS) after first-line chemotherapy with gemcitabine plus carboplatin. In this single blind, parallel, phase 2, randomized trial, patients with NSCLC pathology, age >18 years, Eastern Cooperative Oncology Group (ECOG) performance status (PS) score of 0-2, and advanced stage (IIIB and IV) were treated with up to 6 cycles of gemcitabine 1250 mg/m 2 (day 1 and 8) plus carboplatin AUC 5 (day 1) every 3 weeks. Patients who did not show progression after first-line chemotherapy were randomly assigned to receive switch maintenance with vinorelbine (25 mg/m 2 , day 1, 15) or the best supportive care until disease progression. A total of 100 patients were registered, of whom 34 had a non-progressive response to first-line chemotherapy and randomly received maintenance vinorelbine (n=19) or best supportive care (n=15). The hazard ratio of PFS in the vinorelbine group relative to the best supportive care group was 1.097 (95% confidence interval = 0.479-2.510; P-value =0.827). There was no significant difference between the overall survival for the two groups (P=0.068). Switch maintenance strategies are beneficial, but defining the right candidates for treatment is a problem. Moreover, the trial designs do not always reflect the real-world considerations. Switch maintenance therapy with vinorelbine, though had tolerable toxicity, did not improve PFS in patients with NSCLC. Therefore, other agents should be considered in this setting.

Rationale: Cancer stem cells (CSCs) have been implicated as the seeds of therapeutic resistance and metastasis, due to their unique abilities of self-renew, wide differentiation potentials and resistance to most conventional therapies. It is a proactive strategy for cancer therapy to eradicate CSCs. Methods: Tumor tissue-derived breast CSCs (BCSC), including XM322 and XM607, were isolated by fluorescence-activated cell sorting (FACS); while cell line-derived BCSC, including MDA-MB-231.SC and MCF-7.SC, were purified by magnetic-activated cell sorting (MACS). Analyses of microRNA and mRNA expression array profiles were performed in multiple breast cell lines. The mentioned nanoparticles were constructed following the standard molecular cloning protocol. Tissue microarray analysis has been used to study 217 cases of clinical breast cancer specimens. Results: Here, we have successfully established four long-term maintenance BCSC that retain their tumor-initiating biological properties. Our analyses of microarray and qRT-PCR explored that miR-34a is the most pronounced microRNA for investigation of BCSC. We establish hTERT promoter-driven VISA delivery of miR-34a (TV-miR-34a) plasmid that can induce high throughput of miR-34a expression in BCSC. TV-miR-34a significantly inhibited the tumor-initiating properties of long-term-cultured BCSC in vitro and reduced the proliferation of BCSC in vivo by an efficient and safe way. TV-miR-34a synergizes with docetaxel, a standard therapy for invasive breast cancer, to act as a BCSC inhibitor. Further mechanistic investigation indicates that TV-miR-34a directly prevents C22ORF28 accumulation, which abrogates clonogenicity and tumor growth and correlates with low miR-34 and high C22ORF28 levels in breast cancer patients. Conclusion: Taken together, we generated four long-term maintenance BCSC derived from either clinical specimens or cell lines, which would be greatly beneficial to the research progress in breast cancer patients. We further developed the non-viral TV-miR-34a plasmid, which has a great potential to be applied as a clinical application for breast cancer therapy. PMID:29187905

Background/Aims In patients with coronary artery stents, the cost of clopidogrel has been cited as a factor in the premature discontinuation of therapy. Thus, the introduction of lower-cost generic clopidogrel may increase patient compliance. However, platelet inhibition by generic clopidogrel has not been compared to the original clopidogrel formulation in patients with coronary artery stents. Methods We prospectively enrolled 20 patients receiving chronic therapy with the original clopidogrel bisulfate (Plavix®). After assessing patient compliance with Plavix®, maintenance therapy was switched to generic clopidogrel bisulfate (Plavitor®). Platelet reactivity was assessed at baseline and 30-day after the switch using conventional aggregometry and the VerifyNow P2Y12 assay. Results All patients completed maintenance therapy with Plavitor®. Before and after switching therapy maximal (36.5 ± 7.9% vs. 39.8 ± 16.2%, p = 0.280) and late platelet aggregation (23.5 ± 10.9% vs. 29.1 ± 18.3%, p = 0.156) with 5 µmol/L adenosine diphosphate (ADP) stimulus did not differ. Likewise, 20 µmol/L ADP-induced platelet aggregation and P2Y12 reaction unit in patients on Plavitor® therapy was comparable to that in patients on Plavix® therapy. However, Bland-Altman analysis showed wide limits of agreement between measured platelet reactivity on Plavix® vs. Plavitor® therapies. Conclusions Among patients on Plavix® maintenance therapy with coronary stents, replacement with Plavitor® shows a comparable inhibition of ADP-induced platelet aggregation. However, due to poor inter-therapy agreement, between two regimens, physicians may be cautious when introducing generic clopidogrel bisulfate. PMID:20526388

Circulating memory B cells are severely reduced in the peripheral blood of HIV-1-infected patients. We investigated whether dysfunctional serologic memory to non-HIV antigens is related to disease progression by evaluating the frequency of memory B cells, plasma IgG, plasma levels of antibodies to measles, and Streptococcus pneumoniae, and enumerating measles-specific antibody-secreting cells in patients with primary, chronic, and long-term nonprogressive HIV-1 infection. We also evaluated the in vitro production of IgM and IgG antibodies against measles and S pneumoniae antigens following polyclonal activation of peripheral blood mononuclear cells (PBMCs) from patients. The percentage of memory B cells correlated with CD4+ T-cell counts in patients, thus representing a marker of disease progression. While patients with primary and chronic infection had severe defects in serologic memory, long-term nonprogressors had memory B-cell frequency and levels of antigen-specific antibodies comparable with controls. We also evaluated the effect of antiretroviral therapy on these serologic memory defects and found that antiretroviral therapy did not restore serologic memory in primary or in chronic infection. We suggest that HIV infection impairs maintenance of long-term serologic immunity to HIV-1-unrelated antigens and this defect is initiated early in infection. This may have important consequences for the response of HIV-infected patients to immunizations.

The role of thyroid hormone in trophoblast function, early pregnancy maintenance, and fetal neurodevelopment.

To review the literature on the roles of thyroid hormone in trophoblast function, early pregnancy maintenance, and fetal neurodevelopment. MEDLINE was searched for English-language papers published from 1971 to 2003, using the key words "brain," "hypothyroidism," "placenta," "pregnancy," "threatened abortion," "thyroid hormone," "thyroid hormone receptor," "thyroid hormone replacement therapy," "thyroid hormone-responsive gene," and "trophoblast." Transplacental transfer of thyroid hormone occurs before the onset of fetal thyroid hormone secretion. Thyroid hormone receptors and iodothyronine deiodinases are present in the placenta and the fetal central nervous system early in pregnancy, and thyroid hormone plays a crucial role both in trophoblast function and fetal neurodevelopment. Maternal hypothyroxinemia is associated with a high rate of spontaneous abortion and long-term neuropsychological deficits in children born of hypothyroid mothers. Maternal iodine deficiency also causes a wide spectrum of neuropsychological disorders in children, ranging from subclinical deficits in cognitive motor and auditory functions to hypothyroid-induced cognitive impairment in infants. However, these conditions are preventable when iodine supplementation is initiated before the second trimester. Although thyroid hormone replacement therapy is effective for reducing the adverse effects complicated by maternal hypothyroidism, the appropriate dose of thyroid hormone is mandatory in protecting the early stage of pregnancy. Close monitoring of maternal thyroid hormone status and ensuring adequate maternal thyroid hormone levels in early pregnancy are of great importance to prevent miscarriage and neuropsychological deficits in infants.

Recent advances in experimental technologies and cancer models have made possible to demonstrate that the tumor is a dynamic system comprising heterogeneous populations of cancer cells organized in a hierarchical fashion with cancer stem cells (CSCs) at the apex. CSCs are immature cells characterized by self-renewal property and long-term repopulation potential. CSCs have been causally linked to cancer initiation, propagation, spreading, recurrence and relapse as well as to resistance to anticancer therapy. A growing body of evidence suggests that the function and physiology of CSCs may be influenced by genetic/epigenetic factors and tumor environment. In this context, macroautophagy is a lysosomal degradative process (herein referred to as autophagy) critical for the adaptive response to stress and the preservation of cellular and tissue homeostasis in all eukaryotes that may have a crucial role of in the origin, maintenance and invasiveness of CSCs. The activation of the autophagic machinery is also considered as an adaptive response of CSCs to perturbation of tumor microenvironment, caused for instance by anticancer therapy. Nevertheless, compelling preclinical and clinical evidence on the cytoprotective role of autophagy for CSCs is still missing. Here, we summarize the results on the contribution of autophagy in CSCs and how it impacts tumorigenesis and tumor progression. We also discuss the therapeutical potential of the modulation of autophagy as a means to eradicate CSCs.

Epidermolysis bullosa (EB) is an acquired disease or inherited as either autosomal dominant or recessive with an incidence of 1/50,000. The prominent clinical characteristic of the disease is the development of bullae or vesicles in mucosa or skin in response to minor trauma. A female patient with a dystrophic type of EB had been put in a maintenance regimen after completion of the initial phase of periodontal therapy and followed for 7 years. The purpose of this report is to document acellular dermal matrix allograft application to increase the width of the attached gingiva in this patient experiencing difficulty in chewing and performing plaque control due to the dramatic loss of attached gingiva after 7 years of supportive periodontal therapy. Under local anaesthesia and antibiotic coverage, the acellular dermal matrix allograft was applied in the anterior region of the upper jaw in order to increase the width of attached gingiva, thereby improving patient comfort. The healing was uneventful and a significant gain in attached gingiva dimensions was observed 9 months after the periodontal surgery. The procedure avoided a second surgical site, provided satisfactory results from an aesthetic point of view, and improved patient comfort. Acellular dermal matrix allograft may be regarded as an alternative in the treatment of EB cases to increase the width of attached gingiva and facilitate maintenance of the dentition.

Performance improvement is a mainstay of operations management and maintenance of certification. In this study at a University Hospital inpatient rehabilitation unit, Lean management techniques were used to manage throughput of patients into and out of the inpatient rehabilitation unit. At the start of this process, the average admission time to the rehabilitation unit was 5:00 p.m., with a median time of 3:30 p.m., and no patients received therapy on the day of admission. Within 8 mos, the mean admission time was 1:22 p.m., 50% of the patients were on the rehabilitation unit by 1:00 p.m., and more than 70% of all patients received therapy on the day of admission. Negative variance from this performance was evaluated, the identification of inefficient discharges holding up admissions as a problem was identified, and a Lean workshop was initiated. Once this problem was tackled, the prime objective of 70% of patients receiving therapy on the date of admission was consistently met. Lean management tools are effective in improving throughput on an inpatient rehabilitation unit.

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.

To conduct a quasi-experimental comparison of early clinical outcomes between injectable, sustained-release, depot naltrexone formulation versus oral naltrexone maintenance therapy in individuals with opiate dependence. Early retention in treatment and urine-confirmed opiate use in the first 8 weeks postdetoxification were compared between patients (diagnosed as opiate-dependent according to DSM-IV criteria) participating in 2 concurrently run randomized clinical trials of oral (n = 69; patients treated from September 1999 to May 2002) and long-acting injectable (n = 42; patients treated from November 2000 to June 2003) naltrexone maintenance therapy with psychosocial therapy. Long-acting injectable naltrexone produced significantly better outcome than oral naltrexone on days retained in treatment (F(1,106) = 6.49, P = .012) and for 1 measure of opiate use (F(1,106) = 5.26, P = .024); other measures were not significantly different, but differences were in the same direction. In subanalyses, there were interaction effects between baseline heroin use severity and type of treatment. In subanalyses, heroin users with more severe baseline use showed better retention with oral naltrexone maintenance therapy combined with intensive psychotherapy (behavioral naltrexone therapy) as compared to retention shown by severe heroin users treated with long-acting naltrexone injections combined with standard cognitive-behavioral therapy (χ²(1)= 9.31, P = .002); less severe heroin users evidenced better outcomes when treated with long-acting injectable naltrexone. This quasi-experimental analysis provides tentative indications of superior outcomes for heroin-dependent patients treated with long-acting injectable naltrexone compared to oral naltrexone. The finding that heroin users with more severe baseline use achieved better outcomes with oral naltrexone is most probably attributable to the intensive nature of the psychosocial treatments provided and points to the opportunity for continued research in augmenting injectable naltrexone with psychosocial strategies to further improve outcome, especially in individuals with more severe use. The results should be considered exploratory given the quasi-experimental nature of the study. © Copyright 2010 Physicians Postgraduate Press, Inc.

Advancements in treatment have improved the prognosis of children with acute lymphoblastic leukemia (ALL). Therefore, there is a need to explore health-related quality of life (HRQOL) in depth, specifically in maintenance therapy, where the available data are minimal. This study was conducted to assess the varied items listed in the domains of HRQOL of Children with ALL during maintenance therapy from a parent's perspective. Forty children on the maintenance therapy of ALL, 40 siblings, and 40 healthy children were enrolled, and the HRQOL was assessed by parent proxy reports and child self-reports using PedsQL generic core 4.0 in local language. Parents significantly overrated the HRQOL of ALL patients, their siblings, and healthy children in comparison with child self-report in all domains of health. The HRQOL of children with ALL on maintenance therapy was significantly poorer than siblings and healthy children, but their ability to self-care, household work, attentiveness, and ability to do homework were not affected as per parents' reports. Parents reported that absenteeism because of sickness and hospital visits was more among children with ALL than siblings and healthy children. Children with ALL had emotional problems such as fear, anger, sleeping problems, and worries. In a social health domain, parents reported difficulty in competing among children with ALL. The HRQOL of siblings was as good as healthy children in physical, social, and school health domains as per parents' reports. In our cohort, parents overrated HRQOL in all groups of children. The study identified the various items in each domain of HRQOL that were affected in children with ALL from parents' perspective; this would guide health care professionals to focus on these specific items so as to improve the overall HRQOL of children with ALL.

The efficacy of hypotonic and near-isotonic saline for parenteral fluid therapy given at low maintenance rate in preventing significant change in plasma sodium in post-operative pediatric patients: protocol for a prospective randomized non-blinded study

PubMed Central

2011-01-01

Background Hyponatremia is the most frequent electrolyte abnormality observed in post-operative pediatric patients receiving intravenous maintenance fluid therapy. If plasma sodium concentration (p-Na+) declines to levels below 125 mmol/L in < 48 h, transient or permanent brain damage may occur. There is an intense debate as to whether the administered volume (full rate vs. restricted rate of infusion) and the composition of solutions used for parenteral maintenance fluid therapy (hypotonic vs. isotonic solutions) contribute to the development of hyponatremia. So far, there is no definitive pediatric data to support a particular choice of parenteral fluid for maintenance therapy in post-surgical patients. Methods/Design Our prospective randomized non-blinded study will be conducted in healthy children and adolescents aged 1 to 14 years who have been operated for acute appendicitis. Patients will be randomized either to intravenous hypotonic (0.23% or 0.40% sodium chloride in glucose, respectively) or near-isotonic (0.81% sodium chloride in glucose) solution given at approximately three-fourths of the average maintenance rate. The main outcome of interest from this study is to evaluate 24 h post-operatively whether differences in p-Na+ between treatment groups are large enough to be of clinical relevance. In addition, water and electrolyte balance as well as regulatory hormones will be measured. Discussion This study will provide valuable information on the efficacy of hypotonic and near-isotonic fluid therapy in preventing a significant decrease in p-Na+. Finally, by means of careful electrolyte and water balance and by measuring regulatory hormones our results will also contribute to a better understanding of the physiopathology of post-operative changes in p-Na+ in a population at risk for hyponatremia. Trial registration The protocol for this study is registered with the current controlled trials registry; registry number: ISRCTN43896775. PMID:21729308

There is as yet no consensus as to the best choice among the three treatment options (maintenance, complete chemotherapy-free intervals [CFIs], and continuous) for metastatic colorectal cancer (CRC). We performed a meta-analysis of six trials (N = 2, 454 patients) to compare the safety and efficacy of those three treatment strategies. Maintenance appeared to offer an advantage over CFI with respect to progression-free survival (PFS) (hazard ratio [HR]: 0.53, 95% confidence interval [CI], 0.40–0.69). PFS and overall survival (OS) were comparable between the maintenance and continuous strategies (HR: 1.18, 95% CI, 0.96–1.46; HR: 1.05, 95% CI, 0.98–1.27, respectively), as was OS between the maintenance and CFI strategies (HR: 0.84; 95% CI, 0.70–1.00). The incidence of grade 3/4 toxicity, including neutropenia, neuropathy, hand-foot syndrome and fatigue, was lower with maintenance than with continuous therapy. A maintenance regimen utilizing bevacizumab-based doublets appeared to confer a slight advantage over bevacizumab monotherapy with respect to PFS (P = 0.011). Maintenance appeared to reduce cumulative grade 3/4 toxicity as compared to the continuous strategy, while showing comparable efficacy. Bevacizumab-based doublets appeared to be of particular value in patients with metastatic CRC. PMID:27072579

Mucosal healing is an important therapeutic endpoint in the management of Crohn's disease (CD) and ulcerative colitis (UC). Limited data exist regarding the comparative efficacy of various therapies in achieving this outcome. To perform a systematic review and meta-analysis of biologics for induction and maintenance of mucosal healing in Crohn's disease and ulcerative colitis. We performed a systematic review and meta-analysis of randomised controlled trials (RCT) examining mucosal healing as an endpoint of immunosuppressives, anti-tumour necrosis factor α (anti-TNF) or anti-integrin monoclonal antibody therapy for moderate-to-severe CD or UC. Pooled effect sizes for induction and maintenance of mucosal healing were calculated and pairwise treatment comparisons evaluated using a Bayesian network meta-analysis. A total of 12 RCTs were included in the meta-analysis (CD - 2 induction, 4 maintenance; UC - 8 induction, 5 maintenance). Duration of follow-up was 6-12 weeks for induction and 32-54 weeks for maintenance trials. In CD, anti-TNFs were more effective than placebo for maintaining mucosal healing [28% vs. 1%, Odds ratio (OR) 19.71, 95% confidence interval (CI) 3.51-110.84]. In UC, anti-TNFs and anti-integrins were more effective than placebo for inducing (45% vs. 30%) and maintaining mucosal healing (33% vs. 18%). In network analysis, adalimumab therapy was inferior to infliximab [OR 0.45, 95% credible interval (CrI) 0.25-0.82] and combination infliximab-azathioprine (OR 0.32, 95% CrI 0.12-0.84) for inducing mucosal healing in UC. There was no statistically significant pairwise difference between vedolizumab and anti-TNF agents in UC. Anti-TNF and anti-integrin biological agents are effective in inducing mucosal healing in UC, with adalimumab being inferior to infliximab or combination therapy. Infliximab and adalimumab were similar in CD. © 2017 John Wiley & Sons Ltd.

Short-term efficacy of induction therapy with intravenous immunoglobulin (Ig) in patients with chronic inflammatory demyelinating polyneuropathy (CIDP) is well established. However, data of previous studies on maintenance therapy were limited up to 24-week treatment period. We aimed to investigate the efficacy and safety of longer-term intravenous Ig therapy for 52 weeks. This study was an open-label phase 3 clinical trial conducted in 49 Japanese tertiary centres. 49 patients with CIDP who fulfilled diagnostic criteria were included. After an induction intravenous Ig therapy (0.4 g/kg/day for five consecutive days), maintenance dose intravenous Ig (1.0 g/kg) was given every 3 weeks for up to 52 weeks. The primary outcome measures were the responder rate at week 28 and relapse rate at week 52. The response and relapse were defined with the adjusted Inflammatory Neuropathy Cause and Treatment scale. At week 28, the responder rate was 77.6% (38/49 patients; 95% CI 63% to 88%), and the 38 responders continued the maintenance therapy. At week 52, 4 of the 38 (10.5%) had a relapse (95% CI 3% to 25%). During 52 weeks, 34 (69.4%) of the 49 enrolled patients had a maintained improvement. Adverse events were reported in 94% of the patients; two patients (66-year-old and 76-year-old men with hypertension or diabetes) developed cerebral infarction (lacunar infarct with good recovery), and the other adverse effects were mild and resolved by the end of the study period. Maintenance treatment with 1.0 g/kg intravenous Ig every 3 weeks is an efficacious therapy for patients with CIDP, and approximately 70% of them had a sustained remission for 52 weeks. Thrombotic complications should be carefully monitored, particularly in elderly patients with vascular risk factors.

Treatment of inflammatory bowel disease: A review of medical therapy

PubMed Central

Kozuch, Patricia L; Hanauer, Stephen B

2008-01-01

Crohn’s disease (CD) and ulcerative colitis (UC) are chronic inflammatory diseases of the gastrointestinal tract. While a cure remains elusive, both can be treated with medications that induce and maintain remission. With the recent advent of therapies that inhibit tumor necrosis factor (TNF) alpha the overlap in medical therapies for UC and CD has become greater. Although 5-ASA agents have been a mainstay in the treatment of both CD and UC, the data for their efficacy in patients with CD, particularly as maintenance therapy, are equivocal. Antibiotics may have a limited role in the treatment of colonic CD. Steroids continue to be the first choice to treat active disease not responsive to other more conservative therapy; non-systemic steroids such as oral and rectal budesonide for ileal and right-sided CD and distal UC respectively are also effective in mild-moderate disease. 6-mercaptopurine (6-MP) and its prodrug azathioprine are steroid-sparing immunomodulators effective in the maintenance of remission of both CD and UC, while methotrexate may be used in both induction and maintenance of CD. Infliximab and adalimumab are anti-TNF agents approved in the US and Europe for the treatment of Crohn's disease, and infliximab is also approved for the treatment of UC. PMID:18200659

This phase II study was performed to evaluate the efficacy and safety of cisplatin/pemetrexed combined with 15 mg/kg of bevacizumab followed by pemetrexed/bevacizumab maintenance therapy as first-line chemotherapy in advanced non-squamous non-small cell lung cancer (NSCLC) limited to epidermal growth factor receptor (EGFR)-wild type. Fifty patients with advanced or metastatic EGFR-wild type NSCLC aged < 75 years old were enrolled in the study. The patients were treated with four cycles of cisplatin (75 mg/m 2 , day 1), pemetrexed (500 mg/m 2 , days 1), and bevacizumab (15 mg/kg, day 1), every 3 weeks, followed by pemetrexed plus bevacizumab maintenance until progression for achieving a response over stable disease after induction chemotherapy. Partial response and stable disease were observed in 35 (objective response rate: 70, 95% CI: 55.4-82.1%) and 9 patients, respectively, and 39 (78%) patients received pemetrexed plus bevacizumab maintenance therapy. Median progression-free survival and overall survival periods were 12.0 months (95% CI: 7.5-16.5 months) and 31.0 months (95% CI: 22.2-39.8 months), respectively. Grade 3 adverse events included neutropenia (14%), nausea (10%), anorexia (18%), and hypertension (8%). Coagulation disorder was observed in one patient, but all of these events were reversible and resulted in no treatment-related deaths. The combination of cisplatin/pemetrexed/bevacizumab followed by pemetrexed/bevacizumab maintenance therapy exhibited favorable efficacy and manageable toxicity profiles in patients with EGFR-wild type non-squamous NSCLC (UMIN-CTR number: UMIN000003645).

To compare the cost-effectiveness of therapy of gastroesophageal reflux disease with esomeprazole and other proton pump inhibitors (PPIs) in Poland. Studies comparing esomeprazole with other PPIs in the treatment of erosive esophagitis, non-erosive reflux disease and gastroesophageal reflux disease maintenance therapy were systematically reviewed. 9 randomized clinical trials were selected, meta-analyses were conducted. Cost data derived from Polish Ministry of Health and Pharmacies in Wroclaw. In the treatment of erosive esophagitis esomeprazole was significantly more effective than other PPIs. Both for 4- and 8-week therapy respective incremental cost-effectiveness ratio values were acceptably low. Differences in effectiveness of non-erosive reflux disease therapy were not significant. The replacement of pantoprazole 20 mg with more effective esomeprazole 20 mg in the 6-month maintenance therapy was associated with a substantially high incremental cost-effectiveness ratio.

Brain tumor initiating cells (BTICs), also known as cancer stem cells, hijack high-affinity glucose uptake active normally in neurons to maintain energy demands. Here we link metabolic dysregulation in human BTICs to a nexus between MYC and de novo purine synthesis, mediating glucose-sustained anabolic metabolism. Inhibiting purine synthesis abrogated BTIC growth, self-renewal and in vivo tumor formation by depleting intracellular pools of purine nucleotides, supporting purine synthesis as a potential therapeutic point of fragility. In contrast, differentiated glioma cells were unaffected by the targeting of purine biosynthetic enzymes, suggesting selective dependence of BTICs. MYC coordinated the control of purine synthetic enzymes, supporting its role in metabolic reprogramming. Elevated expression of purine synthetic enzymes correlated with poor prognosis in glioblastoma patients. Collectively, our results suggest that stem-like glioma cells reprogram their metabolism to self-renew and fuel the tumor hierarchy, revealing potential BTIC cancer dependencies amenable to targeted therapy.

The number of hemodialysis patients and dialysis facilities is increasing each year, but there are no surveillance programs validating that the services and equipment of each hemodialysis unit meet specified safety and quality standards. There is a concern that excessive competition and illegal activities committed by some dialysis facilities may violate patients' right to health. Contrastingly, developed countries often have their own survey program to provide initial certification and monitoring to ensure that these clinics continue to meet basic requirements. Because hemodialysis units provide renal replacement therapy to critical patients suffering from severe chronic renal failure, appropriate legal regulation is important for the provision of initial certification and maintenance of facility, equipment, and human resource quality. Therefore, several standards providing minimum requirements for the area of hemodialysis unit, equipment for emergency care, physician and nurse staffs, water purification and quality management are urgently needed.

Chronic insomnia is a prevalent disorder associated with significant psychosocial, health, and economic impacts. Cognitive behavioral therapies (CBTs) and benzodiazepine receptor agonist (BzRA) medications are the most widely supported therapeutic approaches for insomnia management. However, few investigations have directly compared their relative and combined benefits, and even fewer have tested the benefits of sequential treatment for those who do not respond to initial insomnia therapy. Moreover, insomnia treatment studies have been limited by small, highly screened study samples, fixed-dose, and fixed-agent pharmacotherapy strategies that do not represent usual clinical practices. This study will address these limitations. This is a two-site randomized controlled trial, which will enroll 224 adults who meet the criteria for a chronic insomnia disorder with or without comorbid psychiatric disorders. Prospective participants will complete clinical assessments and polysomnography and then will be randomly assigned to first-stage therapy involving either behavioral therapy (BT) or zolpidem. Treatment outcomes will be assessed after 6 weeks, and treatment remitters will be followed for the next 12 months on maintenance therapy. Those not achieving remission will be offered randomization to a second, 6-week treatment, again involving either pharmacotherapy (zolpidem or trazodone) or psychological therapy (BT or cognitive therapy (CT)). All participants will be re-evaluated 12 weeks after the protocol initiation and at 3-, 6-, 9-, and 12-month follow-ups. Insomnia remission, defined categorically as a score < 8 on the Insomnia Severity Index, a patient-reported outcome, will serve as the primary endpoint for treatment comparisons. Secondary outcomes will include sleep parameters derived from daily sleep diaries and from polysomnography, subjective measures of fatigue, mood, quality of life, and functional impairments; and measures of adverse events; dropout rates; and treatment acceptability. Centrally trained therapists will administer therapies according to manualized, albeit flexible, treatment algorithms. This clinical trial will provide new information about optimal treatment sequencing and will have direct implication for the development of clinical guidelines for managing chronic insomnia with and without comorbid psychiatric conditions.

Delayed-release dimethyl fumarate is an oral disease-modifying therapy that has demonstrated significant efficacy in adults with relapsing-remitting multiple sclerosis. Incidences of flushing and gastrointestinal adverse events are common in the first month after delayed-release dimethyl fumarate initiation. Our objective was to propose mitigation strategies for adverse events related to initiation of delayed-release dimethyl fumarate in the treatment of patients with multiple sclerosis. Studies of individually developed mitigation strategies and chart reviews were evaluated. Those results, as well as mitigation protocols developed at multiple sclerosis care centers, are summarized. Key steps to optimize the effectiveness of delayed-release dimethyl fumarate treatment include education prior to and at the time of delayed-release dimethyl fumarate initiation, initiation dose protocol gradually increasing to maintenance dose, dietary suggestions for co-administration with food, gastrointestinal symptom management with over-the-counter medications, flushing symptom management with aspirin, and temporary dose reduction. Using the available evidence from clinical trials and evaluations of post-marketing studies, these strategies to manage gastrointestinal and flushing symptoms can be effective and helpful to the patient when initiating delayed-release dimethyl fumarate.

MAPK13 is preferentially expressed in gynecological cancer stem cells and has a role in the tumor-initiation

Cancer stem-like cells (CSCs)/cancer-initiating cells (CICs) are defined as small subpopulation of cancer cells that are endowed with higher tumor-initiating ability. CSCs/CICs are resistant to standard cancer therapies including chemotherapy and radiotherapy, and they are thus thought to be responsible for cancer recurrence and metastasis. Therefore, elucidation of molecular mechanisms of CSCs/CICs is essential to cure cancer. In this study, we analyzed the gene expression profiles of gynecological CSCs/CICs isolated as aldehyde dehydrogenase high (ALDH{sup high}) cells, and found that MAPK13, PTTG1IP, CAPN1 and UBQLN2 were preferentially expressed in CSCs/CICs. MAPK13 is expressed in uterine, ovary, stomach, colon, liver andmore » kidney cancer tissues at higher levels compared with adjacent normal tissues. MAPK13 gene knockdown using siRNA reduced the ALDH{sup high} population and abrogated the tumor-initiating ability. These results indicate that MAPK13 is expressed in gynecological CSCs/CICs and has roles in the maintenance of CSCs/CICs and tumor-initiating ability, and MAPK13 might be a novel molecular target for treatment-resistant CSCs/CICs.« less

The Evidence Regarding Maintenance Tocolysis

Preterm delivery is a public health issue of major proportion. More than 12% of deliveries in the United States that occur at less than 37 weeks gestation preterm labor (PTL) represents the largest single reason for preterm birth (PTB). Attempts to prevent PTB have been unsuccessful. This paper of maintenance tocolytic therapy will examine the efficacy and safety of the drugs, both oral and subcutaneous, which have been utilized for prolongation of pregnancy following successful arrest of a documented episode of acute preterm labor. The evidence for oral tocolytics as maintenance therapy as well as parenteral medications for such patients is offered. Finally, the effects in the United States of the Food and Drug Administration (FDA) action on such medications are reported. PMID:23577034

To describe and discuss the use of maintenance electroconvulsive therapy (ECT) in a young woman with Down syndrome and depression with catatonia. Clinical case report. A 23-year-old woman with Down syndrome (mosaic type) and a 4-year history of depressed mood triggered by adverse life events presented with mutism, psychomotor retardation, and compromised oral intake. Multiple trials of antidepressant medications were either ineffective or complicated by adverse reactions. She improved rapidly with a course of bilateral ECT but required maintenance ECT to sustain recovery. A series of premorbid, morbid, and post-treatment drawings by the young woman highlight the efficacy of treatment. Electroconvulsive therapy was found to be a safe and effective treatment for life-threatening mental illness in a young woman with Down syndrome who had failed multiple trials of antidepressant medications. This case highlights the importance of considering catatonia as a diagnosis in persons with Down syndrome and the effectiveness of electroconvulsive treatment.

To test if fotemustine administrated at low doses during the maintenance phase of gioblastoma therapy could improve the toxicity profile, without reducing progression-free survival at six months (PFS-6). Patients enrolled were affected by recurrent glioblastoma multiforme, proven by magnetic resonance imaging (MRI), at least six months after radiochemotherapy completion. Fotemustine was administered at an induction dose of 100 mg/m(2) followed by a maintenance dose of 75 mg/m(2). All 15 patients completed the induction phase. Eight patients began maintenance-phase therapy and received a median of three cycles (range=2-6). Grade 3 or more haematological toxicity was not documented. The PFS-6 was 5/15 and the median overall survival was 7.5 months. Haematological toxicity compares favourably with trials using the conventional scheme: no grade 3-4 adverse effects were recorded. This low-dose approach could be considered a compromise treatment whilst waiting for definitive standardization of second-line therapy, in order to reduce severe hematological toxicity.

The efficacy of methadone maintenance therapy for heroin dependence is compromised by the low retention rate. Hypothalamus-pituitary-adrenal (HPA) axis function, which is associated with stress response, and novelty seeking (NS), a personality trait associated with low dopaminergic activity, may play roles in retention. We conducted a prospective study in which HPA axis function and NS were assessed by the dexamethasone suppression test and the Tridimensional Personality Questionnaire at baseline, respectively. The retention rate was assessed at the half- and 1-year points of methadone maintenance therapy. A low suppression rate of dexamethasone suppression test (D%) was associated with a high level of NS. A low D% was associated with half-year dropout, whereas a high level of NS was associated with 1-year dropout. Survival analysis confirmed that D% and NS were significant time-dependent covariates for retention. The findings showed that HPA axis function and NA were associated with retention at different time points.

Therapeutic hypothermia improves the survival and neurodevelopmental outcome of infants with newborn encephalopathy of a hypoxic-ischemic origin. The NICHD Neonatal Research Network (NRN) Whole Body Cooling trial used the Cincinnati Sub-Zero Blanketrol II to achieve therapeutic hypothermia. The Blanketrol III is now available and provides additional cooling modes that may result in better temperature control. This report is a retrospective comparison of infants undergoing hypothermia using two different cooling modes of the Blanketrol device. Infants from the NRN trial were cooled with the Blanketrol II using the Automatic control mode (B2 cohort) and were compared with infants from two new NRN centers that adopted the NRN protocol and used the Blanketrol III in a gradient mode (B3 cohort). The primary outcome was the percent time the esophageal temperature stayed between 33°C and 34°C (target 33.5°C) during maintenance of hypothermia. Cohorts had similar birth weight, gestational age, and level of encephalopathy at the initiation of therapy. Baseline esophageal temperature differed between groups (36.6°C ± 1.0°C for B2 vs. 33.9°C ± 1.2°C for B3, p<0.0001) reflecting the practice of passive cooling during transport prior to initiation of active device cooling in the B3 cohort. This difference prevented comparison of temperatures during induction of hypothermia. During maintenance of hypothermia the mean and standard deviation of the percent time between 33°C and 34°C was similar for B2 compared to B3 cohorts (94.8% ± 0.1% vs. 95.8% ± 0.1%, respectively). Both the automatic and gradient control modes of the Blanketrol devices appear comparable in maintaining esophageal temperature within the target range during maintenance of therapeutic hypothermia.

To evaluate the feasibility of clinical application for genetic based dosing algorithm in the predication of warfarin maintenance dose in Chinese population. The clinical data were collected and blood samples harvested from a total of 126 patients undergoing heart valve replacement. The genotypes of VKORC1 and CYP2C9 were determined by melting curve analysis after PCR. They were divided randomly into the study and control groups. In the study group, the first three doses of warfarin were prescribed according to the predicted warfarin maintenance dose while warfarin was initiated at 2.5 mg/d in the control group. The warfarin doses were adjusted according to the measured international normalized ratio (INR) values. And all subjects were followed for 50 days after an initiation of warfarin therapy. At the end of a 50-day follow-up period, the proportions of the patients on a stable dose were 82.4% (42/51) and 62.5% (30/48) for the study and control groups respectively. The mean durations of reaching a stable dose of warfarin were (27.5 ± 1.8) and (34.7 ± 1.8) days and the median durations were (24.0 ± 1.7) and (33.0 ± 4.5) days in the study and control groups respectively. Significant differences existed in the durations of reaching a stable dose between the two groups (P = 0.012). Compared with the control group, the hazard ratio (HR) for the duration of reaching a stable dose was 1.786 in the study group (95%CI 1.088 - 2.875, P = 0.026). The predicted dosing algorithm incorporating genetic and non-genetic factors may shorten the duration of achieving efficiently a stable dose of warfarin. And the present study validates the feasibility of its clinical application.

The incidence of tuberculosis (TB) in end-stage renal disease is significantly higher than that in the general population. Among those with kidney dysfunction, anti-TB treatment is associated with increased side effects, but the effect on healthcare utilization is unknown. Methods/Aim: To assess patient-reported symptoms, adverse effects and describe changes in healthcare utilization patterns during treatment for TB, we conducted a case series (n = 12) of patients receiving maintenance hemodialysis (HD) from Mayo Clinic Dialysis Services and concurrent drug therapy for TB from January 2002 through May 2014. Healthcare utilization (hospitalizations and emergency department (ED) visits independent of hospital admission) was compared before and during treatment. Patients were treated for latent (n = 7) or active (n = 5) TB. The majority of patients with latent disease were treated with isoniazid (n = 5, 71%), while active-disease patients received a 4-drug regimen. Adverse effects were reported in 83% of patients. Compared to measurements prior to drug initiation, serum albumin and dialysis weights were similar at 3 months. Commonly reported anti-TB drug toxicities were described. More than half (58%) of the patients were hospitalized at least once. No ED or hospital admissions occurred in the period prior to drug therapy, but healthcare utilization increased during treatment in the latent disease group (hospitalization rate per person-month: pre 0 vs. post 1). Among HD patients, anti-TB therapy is associated with frequently reported symptoms and increased healthcare utilization. Among this subset, patients receiving treatment for latent disease may be those with greatest increase in healthcare use. Careful monitoring and early complication detection may help optimize medication adherence and minimize hospitalizations. © 2016 S. Karger AG, Basel.

Recent advances in the therapy and prevention of CMV infections.

Nichols, W G; Boeckh, M

2000-02-01

The introduction of highly active antiretroviral therapy (HAART) for HIV has had a major impact on the treatment of CMV disease in HIV-infected individuals. There is mounting evidence that in patients with CMV retinitis who have a sustained response to HAART, CMV maintenance treatment can be discontinued without relapse of retinitis. In HAART-naïve individuals with newly diagnosed CMV retinitis, the optimal timing for the initiation of HAART relative to the start of anti-CMV treatment is currently unknown. New local therapies for CMV retinitis (e.g. ganciclovir implant, the new antisense compound fomivirsen) provide treatment options in situations where high local drug delivery is warranted. A treatment algorithm for CMV disease in the HAART era is proposed. In the transplant setting, ganciclovir and foscarnet remain the major compounds used for treatment of CMV disease. In marrow and stem cell transplant recipients, CMV pneumonia still carries a high mortality. Ganciclovir in combination with CMV-specific immunoglobulin or regular intravenous IG remains the treatment of choice for CMV pneumonia; extended antiviral maintenance for several months is recommended in patients with continued immunosuppression. Preemptive treatment based on virologic markers (e.g. pp65 antigenemia, CMV DNA) has been very successful in reducing the incidence of early CMV disease in the transplant setting. The duration of preemptive treatment should be guided by the underlying immunosuppression and virologic markers. Late CMV disease is a challenge in marrow and stem cell transplant recipients, and occurs increasingly in highly immunosuppressed solid organ transplant recipients as well. Recent advances in prophylaxis strategies include oral ganciclovir for liver transplant recipients and valacyclovir for kidney transplant recipients.

Background/Aims The occurrence of gastroesophageal reflux disease (GERD) is known to be associated with lower post-treatment lower esophageal sphincter pressure in patients with achalasia. This study aimed to elucidate whether GERD after pneumatic balloon dilatation (PD) has a prognostic role and to investigate how the clinical course of GERD is. Methods A total of 79 consecutive patients who were first diagnosed with primary achalasia and underwent PD as an initial treatment were included in this retrospective study. Single PD was performed using a 3.0 cm balloon. The patients were divided into two groups: 1) who developed GERD after PD (GERD group) and 2) who did not develop GERD after PD (non-GERD group). GERD was defined as pathological acid exposure, reflux esophagitis or typical reflux symptoms. Results Twenty one patients (26.6%) developed GERD after PD during follow-up. There were no significant differences between the two groups in demographic or clinical factors including pre- and post-treatment manometric results. All patients in GERD group were well responsive to maintenance proton pump inhibitor therapy including on demand therapy or did not require maintenance. During a median follow-up of 17.8 months (interquartile range, 7.1–42.7 months), achalasia recurred in 15 patients (19.0%). However, the incidence of recurrence did not differ according to the occurrence of GERD after PD. Conclusions GERD often occurs after even a single PD for achalasia. However, GERD after PD is well responsive to PPI therapy. Our data suggest that GERD after PD during follow-up does not appear to have a prognostic role. PMID:24840373

To describe and expand the phenotype of anti-MDA5-associated rapidly progressive interstitial lung disease (MDA5-RPILD) in Canadian patients. All proven cases of MDA5-RPILD hospitalized in the University of Montreal's affiliated centres from 2004 to 2015 were selected for inclusion. Of nine consecutive patients, RPILD was the presenting manifestation in seven, whereas two patients developed RPILD 2 years after the onset of arthritis and of chronic interstitial lung disease. In the case with arthritis, RPILD was probably triggered by initiation of tumour necrosis factor-α-inhibitor therapy. In most patients (89%), RPILD was accompanied by concomitant onset of palmar/lateral finger papules, skin ulcerations, and/or mechanic's hands. All patients experienced profound weight loss over 1-2 months (mean ± SD 10.2 ± 4.8 kg). All had arthralgias and/or arthritis. Six patients were clinically amyopathic; only one patient had creatine kinase (CK) levels > 500 U/L. Initial ferritin and transaminase levels were elevated in 86% and 67% of patients, respectively. The antinuclear antibody (ANA) test was negative for nuclear and cytoplasmic staining; antisynthetase autoantibodies were negative. Three patients died; time from initial symptoms to death ranged from 7 to 15 weeks. All six survivors received mycophenolate mofetil and/or tacrolimus as part of induction and/or maintenance therapy. In an inpatient setting, RPILD associated with characteristic skin rashes, profound weight loss, articular symptoms, normal or low CK with elevated ferritin, and absent fluorescence on ANA testing should alert the clinician to the possibility of MDA5-RPILD. T-cell-mediated therapies may play a role in this highly lethal condition.

Allergic bronchopulmonary aspergillosis (ABPA) affects 3-13% of patients with asthma. Its natural history includes possibly life-threatening exacerbations and evolution towards fixed obstructive ventilatory disorders or even irreversible lung fibrosis lesions. ABPA prognosis is directly associated with exacerbation control and the main objective of the treatment is to decrease their frequency and duration. Recommendations regarding dosage and duration of treatment are not very precise. The currently used combination of itraconazole and corticosteroid therapy has many limitations. The interests of a therapeutic strategy using nebulized liposomal amphotericin B (LAmB) are to heighten antifungal lung tissue concentration, to circumvent drug interactions and decrease the potential toxicity of systemic antifungal treatments. Finally, this association leads to improved eradication of Aspergillus, thereby limiting the risk of side effects and the emergence of treatment-resistant Aspergillus strains. This is a phase II, multicentre, randomized, single blind, controlled therapeutic study, with the objective of comparing the potential benefit on exacerbation control of a maintenance therapy by LAmB nebulization. The main objective of the study is to compare the incidence of severe clinical exacerbations in ABPA treatment, between a maintenance treatment strategy with nebulized LAmB and a conventional strategy without antifungal maintenance therapy. The results will guide practitioners in the management of ABPA treatments and help to define the place of aerosols of LAmB on "evidence base medicine" criteria. Copyright © 2017 SPLF.

Injection drug use is the primary mode of transmission for hepatitis C virus (HCV) infection. Prior studies suggest opioid agonist therapy may reduce the incidence of HCV infection among injection drug users; however, little is known about the effects of this therapy in younger users. To evaluate whether opioid agonist therapy was associated with a lower incidence of HCV infection in a cohort of young adult injection drug users. Observational cohort study conducted from January 3, 2000, through August 21, 2013, with quarterly interviews and blood sampling. We recruited young adult (younger than 30 years) injection drug users who were negative for anti-HCV antibody and/or HCV RNA. Substance use treatment within the past 3 months, including non-opioid agonist forms of treatment, opioid agonist (methadone hydrochloride or buprenorphine hydrochloride) detoxification or maintenance therapy, or no treatment. Incident HCV infection documented with a new positive result for HCV RNA and/or HCV antibodies. Cumulative incidence rates (95% CI) of HCV infection were calculated assuming a Poisson distribution. Cox proportional hazards regression models were fit adjusting for age, sex, race, years of injection drug use, homelessness, and incarceration. Baseline characteristics of the sample (n = 552) included median age of 23 (interquartile range, 20-26) years; 31.9% female; 73.1% white; 39.7% who did not graduate from high school; and 69.2% who were homeless. During the observation period of 680 person-years, 171 incident cases of HCV infection occurred (incidence rate, 25.1 [95% CI, 21.6-29.2] per 100 person-years). The rate ratio was significantly lower for participants who reported recent maintenance opioid agonist therapy (0.31 [95% CI, 0.14-0.65]; P = .001) but not for those who reported recent non-opioid agonist forms of treatment (0.63 [95% CI, 0.37-1.08]; P = .09) or opioid agonist detoxification (1.45 [95% CI, 0.80-2.69]; P = .23). After adjustment for other covariates, maintenance opioid agonist therapy was associated with lower relative hazards for acquiring HCV infection over time (adjusted hazard ratio, 0.39 [95% CI, 0.18-0.87]; P = .02). In this cohort of young adult injection drug users, recent maintenance opioid agonist therapy was associated with a lower incidence of HCV infection. Maintenance treatment with methadone or buprenorphine for opioid use disorders may be an important strategy to prevent the spread of HCV infection among young injection drug users.

We used objective and subjective measures of improvement to compare outcomes based on test method. Patients underwent 1 of 3 protocols: SPT, screening SPT followed by IDT, or IVT. We used institution billing data to do a cost analysis of these tests. The time to maintenance (TTM) therapy was analyzed and patients were stratified into high and low reactors. The Rhinoconjunctivitis Quality of Life Questionnaire (RQLQ) was used to quantify symptoms pre-maintenance and post-maintenance. Of 177 patients (SPT, n = 40; IVT, n = 91; IDT, n = 46), 115 (SPT, n = 35; IVT, n = 39; IDT, n = 41) were high reactors. Out of 90 patients (SPT, n = 17; IVT, n = 37; IDT, n = 36) reaching maintenance, 58 were high reactors (SPT, n = 15; IVT, n = 12; IDT, n = 31). Overall, SPT, IVT, and IDT median TTM were 542, 329, and 578.5 days, respectively. IDT TTM was shorter compared to IVT overall and in high reactors (hazard ratio [HR] = 1.91, p = 0.02; HR = 2.12, p = 0.03), but was not significant compared to SPT high reactors (p = 0.33). The IDT cost was $62.66, translating to an incremental cost-effectiveness ratio of $0.23 per day of shortened TTM. Median RQLQ change for the SPT, IVT, and IDT groups was 6.5, 1, and 1.5, respectively, but was not significant (p = 0.60). IDT reached maintenance immunotherapy quicker than IVT but there was no difference compared to SPT. TTM did not correlate with improvements in patient symptoms between testing methods. This study represents a novel comparison of outcomes based on initial allergy testing method. © 2017 ARS-AAOA, LLC.

Gallbladder cancer typically follows an aggressive course, with chemotherapy the standard of care for advanced disease; complete remissions are rarely encountered. The epidermal growth factor receptor (EGFR) is a promising therapeutic target but the activity of single agent oral EGFR tyrosine kinase inhibitors is low. There have been no previous reports of chemotherapy plus an EGFR-tyrosine kinase inhibitor (TKI) to treat gallbladder cancer or correlations of response with the mutation status of the tyrosine kinase domain of the EGFR gene. A 67 year old man with metastatic gallbladder cancer involving the liver and abdominal lymph nodes was treated with gemcitabine (1000 mg/m2) on day 1 and 8 every 21 days as well as daily erlotinib (100 mg). After four cycles of therapy, the CA 19-9 normalized and a PET/CT showed a complete remission; this response was maintained by the end of 12 cycles of therapy. Gemcitabine was then discontinued and single agent erlotinib was continued as maintenance therapy. The disease remains in good control 18 months after initiation of therapy, including 6 months on maintenance erlotinib. The only grade 3 toxicity was a typical EGFR-related skin rash. Because of the remarkable response to erlotinib plus gemcitabine, we performed tumor genotyping of the EGFR gene for response predicting mutations in exons 18, 19 and 21. This disclosed the wild-type genotype with no mutations found. This case report demonstrates a patient with stage IV gallbladder cancer who experienced a rarely encountered complete, prolonged response after treatment with an oral EGFR-TKI plus chemotherapy. This response occurred in the absence of an EGFR gene mutation. These observations should inform the design of clinical trials using EGFR-TKIs to treat gallbladder and other biliary tract cancers; such trials should not select patients based on EGFR mutation status.

Toh, Tan Boon; Lim, Jhin Jieh; Chow, Edward Kai-Hua

Compelling evidence have demonstrated that bulk tumors can arise from a unique subset of cells commonly termed "cancer stem cells" that has been proposed to be a strong driving force of tumorigenesis and a key mechanism of therapeutic resistance. Recent advances in epigenomics have illuminated key mechanisms by which epigenetic regulation contribute to cancer progression. In this review, we present a discussion of how deregulation of various epigenetic pathways can contribute to cancer initiation and tumorigenesis, particularly with respect to maintenance and survival of cancer stem cells. This information, together with several promising clinical and preclinical trials of epigenetic modulating drugs, offer new possibilities for targeting cancer stem cells as well as improving cancer therapy overall.

Current trends in immunosuppressive therapies for renal transplant recipients.

Current trends in immunosuppressive therapies for renal transplant recipients are reviewed. The common premise for immunosuppressive therapies in renal transplantation is to use multiple agents to work on different immunologic targets. The use of a multidrug regimen allows for pharmacologic activity at several key steps in the T-cell replication process and lower dosages of each individual agent, thereby producing fewer drug-related toxicities. In general, there are three stages of clinical immunosuppression: induction therapy, maintenance therapy, and treatment of an established acute rejection episode. Only immunosuppressive therapies used for maintenance therapy are discussed in detail in this review. The most common maintenance immunosuppressive agents can be divided into five classes: (1) the calcineurin inhibitors (CNIs) (cyclosporine and tacrolimus), (2) costimulation blockers (belatacept), (3) mammalian target of rapamycin inhibitors (sirolimus and everolimus), (4) antiproliferatives (azathioprine and mycophenolic acid derivatives), and (5) corticosteroids. Immunosuppressive regimens vary among transplantation centers but most often include a CNI and an adjuvant agent, with or without corticosteroids. Selection of appropriate immunosuppressive regimens should be patient specific, taking into account the medications' pharmacologic properties, adverse-event profile, and potential drug-drug interactions, as well as the patient's preexisting diseases, risk of rejection, and medication regimen. Advancements in transplant immunosuppression have resulted in a significant reduction in acute cellular rejection and a modest increase in long-term patient and graft survival. Because the optimal immunosuppression regimen is still unknown, immunosuppressant use should be influenced by institutional preference and tailored to the immunologic risk of the patient and adverse-effect profile of the drug.

In this Phase 1b study, the safety and tolerability of maintenance therapy, comprising lenalidomide (0-25 mg, days 5-25) in combination with azacitidine (50-75 mg/m(2) , days 1-5) every 28 d, was explored in 40 patients with acute myeloid leukaemia (AML) in complete remission after chemotherapy. Eligibility included AML in first complete remission (CR1) with adverse risk karyotype (n = 8), fms-related tyrosine kinase 3-internal tandem duplication (FLT3-ITD) (n = 5), age ≥60 years (n = 31) or AML in second remission (CR2) (n = 14). Dose-limiting toxicity was not reached. Common toxicities were haematological, infection, injection pain, constipation, fatigue and diarrhoea. In CR1, median relapse-free (RFS) and overall survival (OS) was 12 and 20 months, respectively. In CR2, median RFS was 11 months, with median OS not yet reached. Among 29 patients with intermediate cytogenetic risk, RFS was 50% at 24 months. There were five patients with concomitant FLT3-ITD and nucleophosmin (NPM1) mutation; none have relapsed and all are still alive after 17-39 months. Maintenance lenalidomide/azacitidine augmented the function of cytotoxic T lymphocytes, particularly in patients with NPM1 mutation. The lenalidomide/azacitidine maintenance combination was effective in suppressing residual DNA (cytosine-5-)-methyltransferase 3 alpha (DNMT3A)-positive disease, resulting in sustained remission in patients with concurrent NPM1 mutation. Azacitidine/lenalidomide as maintenance therapy for high-risk AML warrants further exploration. © 2015 John Wiley & Sons Ltd.

Long term longitudinal data are scarce on epidemiological characteristics and patient outcomes in patients on maintenance dialysis, especially in Switzerland. We examined changes in epidemiology of patients undergoing renal replacement therapy by either hemodialysis or peritoneal dialysis over four decades. Single center retrospective study including all patients which initiated dialysis treatment for ESRD between 1970 and 2008. Analyses were performed for subgroups according to dialysis vintage, based on stratification into quartiles of date of first treatment. A multivariate model predicting death and survival time, using time-dependent Cox regression, was developed. 964 patients were investigated. Incident mean age progressively increased from 48 ± 14 to 64 ± 15 years from 1st to 4th quartile (p < 0.001), with a concomitant decrease in 3- and 5-year survival from 72.2 to 67.7%, and 64.1 to 54.8%, respectively. Nevertheless, live span continuously increased from 57 ± 13 to 74 ± 11 years (p < 0.001). Patients transplanted at least once were significantly younger at dialysis initiation, with significantly better survival, however, shortened live span vs. individuals remaining on dialysis. Among age at time of initiating dialysis therapy, sex, dialysis modality and transplant status, only transplant status is a significant independent covariate predicting death (HR: 0.10 for transplanted vs. non-transplanted patients, p = 0.001). Dialysis vintage was associated with better survival during the second vs. the first quartile (p = 0.026). We document an increase of a predominantly elderly incident and prevalent dialysis population, with progressively shortened survival after initiation of renal replacement over four decades, and, nevertheless, a prolonged lifespan. Analysis of the data is limited by lack of information on comorbidity in the study population. Survival in patients on renal replacement therapy seems to be affected not only by medical and technical advances in dialysis therapy, but may mostly reflect progressively lower mortality of individuals with cardiovascular and metabolic complications, as well as a policy of accepting older and polymorbid patients for dialysis in more recent times. This is relevant to make demographic predictions in face of the ESRD epidemic nephrologists and policy makers are facing in industrialized countries.

To evaluate the pattern of prescription and maintenance over time of concomitant methotrexate (MTX), and its impact on a 2-year clinical response in a cohort of rheumatoid arthritis (RA) patients treated with a first-line tumor necrosis factor alpha inhibitor (TNFi). The study population included all RA patients receiving adalimumab or etanercept a as first-line biologic drug, extracted from a local registry. Enrolled patients were stratified into 3 subgroups according to baseline concomitant MTX: no MTX, low-dose MTX (≤10 mg/wk), and high-dose MTX (≥12.5 mg/wk). The 2-year persistence of the initial MTX regimen was computed by the Kaplan-Meier method, and a Cox proportional hazard model was developed to examine potential predictors of MTX withdrawal/change of dosage. European League Against Rheumatism remission and good-to-moderate response were evaluated according to baseline MTX regimen and MTX maintenance over time. A total of 330 patients (163 treated with adalimumab and 167 with etanercept) were included; 141 were prescribed TNFi without MTX and 112 received low-dose and 77 high-dose concomitant MTX. Male sex, younger age, and shorter mean disease duration were predictors of high-dose MTX use. Among MTX users (76.2% parenteral and 23.8% oral), initial MTX dose persisted over time in 79.9% at 1 year and 70.2% at 2 years. Fifty-one patients (27%) underwent MTX dose de-escalation/discontinuation because of intolerance/adverse events. The 2-year EULAR remission rate was higher in the patients receiving and maintaining high-dose MTX than in those receiving low-dose or no MTX (46.2% vs 29.5% and 23.4%, respectively; p =0.009). The same was true for good-to-moderate response rate (71.2% vs 52.6% and 50.4%, respectively; p =0.031). In a real-life setting, about one-third of RA patients treated with TNFis experienced dose reduction/discontinuation of concomitant MTX because of intolerance/adverse events over a 2-year follow-up period. Initial high-dose MTX and its maintenance over time are associated with better 2-year clinical response.

Emerging evidence has emphasized the importance of cancer therapies targeting an abnormal metabolic state of tumor-initiating cells (TICs) in which they retain stem cell-like phenotypes and nicotinamide adenine dinucleotide (NAD+) metabolism. However, the functional role of NAD+ metabolism in regulating the characteristics of TICs is not known. In this study, we provide evidence that the mitochondrial NAD+ levels affect the characteristics of glioma-driven SSEA1+ TICs, including clonogenic growth potential. An increase in the mitochondrial NAD+ levels by the overexpression of the mitochondrial enzyme nicotinamide nucleotide transhydrogenase (NNT) significantly suppressed the sphere-forming ability and induced differentiation of TICs, suggesting a loss of the characteristics of TICs. In addition, increased SIRT3 activity and reduced lactate production, which are mainly observed in healthy and young cells, appeared following NNT-overexpressed TICs. Moreover, in vivo tumorigenic potential was substantially abolished by NNT overexpression. Conversely, the short interfering RNA-mediated knockdown of NNT facilitated the maintenance of TIC characteristics, as evidenced by the increased numbers of large tumor spheres and in vivo tumorigenic potential. Our results demonstrated that targeting the maintenance of healthy mitochondria with increased mitochondrial NAD+ levels and SIRT3 activity could be a promising strategy for abolishing the development of TICs as a new therapeutic approach to treating aging-associated tumors.

The aim of this study was to evaluate efficacy and safety of continuous, low dose of oral, metronomic chemotherapy as maintenance therapy in patients with advanced ovarian carcinoma after complete clinical response to platinum and paclitaxel chemotherapy. In this nonrandomized study, patients older than 18 years, with Eastern Cooperative Oncology Group performance status less than 2, with advanced ovarian carcinoma after complete clinical response to platinum and paclitaxel chemotherapy were enrolled in 2 arms--arm A (maintenance arm), treated with continuous low-dose oral cyclophosphamide 50 mg and methotrexate 2.5 mg, and arm B (observation arm). Both arms were followed up for progression-free survival and toxicity. Thirty patients were accrued in each arm from January 2009 to December 2010 in Ain Shams University Hospitals, where they received the treatment and followed up for disease progression and toxicity. Patients had a median age of 53 years in maintenance arm and 52.5 years in the observational arm, respectively. Over 80% had papillary serous adenocarcinoma, and over 40% of them had a stage IV disease in both arms. After median follow-up of 27 months, patients achieved median progression-free survival of 18 months in maintenance arm (A) and 15.5 months in observational arm (B), respectively. Toxicity profile was excellent with no grade 3 or 4 toxicity reported. Current study may provide an evidence of efficacy and tolerability of continuous low-dose oral cyclophosphamide and methotrexate as a maintenance therapy in patients with advanced ovarian carcinoma after complete clinical response to platinum and paclitaxel chemotherapy.

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.

Aim To evaluate long-term clinical response to periodontal therapy and maintenance in localized aggressive periodontitis (LAP). Materials and Methods One hundred forty-one African-Americans diagnosed with LAP, aged 5–25 years, were enrolled. Patients underwent periodontal mechanical debridement plus one week of amoxicillin/metronidazole. Mechanical therapy was repeated as needed and clinical parameters were recorded at baseline, 3, 6, 12, 18, and 24 months, and 2 additional annual follow-up visits after treatment. Radiographs from primary dentition of patients with LAP in permanent dentition, and additional healthy siblings (HS) were analyzed retrospectively. Results Periodontal therapy significantly improved probing depth and clinical attachment level up to 4 years (mean reductions: 2.18 ± 1.03 and 2.80 ± 1.43 mm, respectively). Percentage of affected sites was reduced at all timepoints and maintained up to 4 years. Noncompliance with antibiotics/appointments negatively affected the treatment response. Ninety percent of LAP patients in permanent dentition and 32% of HS presented radiographic bone loss in primary dentition. Conclusions Mechanical debridement with one-week of systemic antibiotics along with proper periodontal maintenance was effective in the treatment and successful maintenance of LAP for up to 4 years. LAP in permanent dentition may be preceded in the primary dentition. Clinicaltrials.gov #NCT01330719. PMID:27767222

We aimed to quantitatively synthesize data from randomized controlled trials (RCTs) concerning maintenance for multiple myeloma (MM). We searched electronic literature databases and conference proceedings to identify relevant RCTs. We selected eligible RCTs using predefined selection criteria. We conducted meta-analysis comparing maintenance containing new agents and conventional maintenance, and subgroup analysis by transplantation status and mainstay agent as well. We performed trial sequential analysis (TSA) to determine adequacy of sample size for overall and subgroup meta-analyses. We performed network meta-analysis (NMA) to compare and rank included regimens. A total of 22 RCTs involving 9,968 MM patients and 15 regimens were included, the overall quality of which was adequate. Significant heterogeneity was detected for progression-free survival (PFS) but not overall survival (OS). Meta-analyses showed that maintenance containing new agents significantly improved PFS but not OS [PFS: Hazard Ratio (HR) = 0.59, 95% Confidence Interval (CI) = 0.54 to 0.64; OS: HR = 0.93, 95% CI = 0.87 to 1.00], compared with controls. Subgroup analyses revealed lenalidomide (Len)-based therapies better than thalidomide-based ones (HR = 0.50 and 0.66, respectively; P = 0.001). NMA revealed that most of the maintenance regimens containing new agents were significantly better than simple observation in terms of PFS but not OS. Len single agent was the most effective, considering PFS and OS both. We concluded that conventional maintenance has very limited effect. Maintenance containing new agents is highly effective in improving PFS, but has very limited effect on OS. Maintenance with Len may have the largest survival benefits. Emerging strategies may further change the landscape of maintenance of MM.

Maintenance therapy improves outcomes in various tumour types, but cumulative toxic effects limit the choice of drugs. We investigated whether maintenance therapy with vinflunine would delay disease progression in patients with advanced urothelial carcinoma who had achieved disease control with first-line chemotherapy. We did a randomised, controlled, open-label, phase 2 trial in 21 Spanish hospitals. Eligible patients had locally advanced, surgically unresectable, or metastatic transitional-cell carcinoma of the urothelial tract, adequate organ function, and disease control after four to six cycles of cisplatin and gemcitabine (carboplatin allowed after cycle four). Patients were randomly assigned (1:1) to receive vinflunine or best supportive care until disease progression. We initially used block randomisation with a block size of six. Four lists were created for the two stratification factors of starting dose of vinflunine and presence of liver metastases. After a protocol amendment, number of cisplatin and gemcitabine cycles was added as a stratification factor, and eight lists were created, still with a block size of six. Finally, we changed to a minimisation procedure to reduce the risk of imbalance between groups. Vinflunine was given every 21 days as a 20 min intravenous infusion at 320 mg/m 2 or at 280 mg/m 2 in patients with an Eastern Cooperative Oncology Group performance status score of 1, age 75 years or older, previous pelvic radiotherapy, or creatinine clearance lower than 60 mL/min. The primary endpoint was median progression-free survival longer than 5·3 months in the vinflunine group, assessed by modified intention to treat. Comparison of progression-free survival between treatment groups was a secondary endpoint. This trial is registered with ClinicalTrials.gov, number NCT01529411. Between April 12, 2012, and Jan 29, 2015, we enrolled 88 patients, of whom 45 were assigned to receive vinflunine and 43 to receive best supportive care. One patient from the vinflunine group was lost to follow-up immediately after randomisation and was excluded from the analyses. One patient in the best supportive care group became ineligible for the study and did not receive treatment due to a delay in enrolment, but was included in the intention-to-treat efficacy analysis. After a median follow-up of 15·6 months (IQR 8·5-26·0), 29 (66%) of 44 patients in the vinflunine group had disease progression and 24 (55%) had died, compared with 36 (84%) of 43 patients with disease progression and 32 (74%) deaths in the best supportive care group. Median progression-free survival was 6·5 months (95% CI 2·0-11·1) in the vinflunine group and 4·2 months (2·1-6·3) in the best supportive care group (hazard ratio 0·59, 95% CI 0·37-0·96, p=0·031). The most common grade 3 or 4 adverse events were neutropenia (eight [18%] of 44 in the vinflunine group vs none of 42 in the best supportive care group), asthenia or fatigue (seven [16%] vs one [2%]), and constipation (six [14%] vs none). 18 serious adverse events were reported in the vinflunine group and 14 in the best supportive care group. One patient in the vinflunine group died from pneumonia that was deemed to be treatment related. In patients with disease control after first-line chemotherapy, progression-free survival exceeded the acceptable threshold with vinflunine maintenance therapy. Moreover, progression-free survival was longer with vinflunine maintenance therapy than with best supportive care. Vinflunine maintenance had an acceptable safety profile. Further studies of the role of vinflunine are warranted. Pierre-Fabre Médicament. Copyright © 2017 Elsevier Ltd. All rights reserved.

Twelve patients with congestive heart failure receiving maintenance therapy with digoxin and potent diuretics were followed closely during development of hypokalemia and potassium loss. Cardiac arrhythmias compatible with digoxtin toxicity developed in 6 patients in the presence of stable, normal serum digoxin concentrations. The mechanisms involved in the development of the rhythm disturbances are discussed with regard to hypokalaemia, intracellular potassium loss, intra-/extracellular potassium gradients and digoxin, and the significance of maintaining a normal potassium balance in this setting is stressed.

The aim of this study was to explore the recent advances in diagnosis and treatment of gastroesophageal reflux disease (GERD). Previous studies were searched using the terms "gastroesophageal reflux disease" and "diagnosis" or "treatment" in Medline and Pubmed. Articles that were not published in the English language, manuscripts without an abstract, reviews, meta-analysis, and opinion articles were excluded from the review. After a preliminary screening, all of the articles were reviewed and synthesized to provide an overview of the contemporary approaches to GERD. GERD has a variety of symptomatic manifestations, which can be grouped into typical, atypical and extra-esophageal symptoms. Those with the highest specificity for GERD are acid regurgitation and heartburn. In the absence of other alarming symptoms, these symptoms allow one to make a presumptive diagnosis of GERD and initiate empiric therapy. GERD-associated complications include erosive esophagitis, peptic stricture, Barrett's esophagus, esophageal adenocarcinoma and pulmonary disease. Management of GERD may involve lifestyle modifications, medical and surgical therapy. Medical therapy involves acid suppression, which can be achieved with antacids, histamine-receptor antagonists or proton-pump inhibitors. Whereas most patients can be effectively managed with medical therapy, others may go on to require anti-reflux surgery after undergoing a proper pre-operative evaluation. The management of this disease requires a complex approach. Maintenance therapy of GERD after using anti-secretory drugs should be continuously monitored. © Acta Gastro-Enterologica Belgica.

Traditional therapies against cancer, chemo- and radiotherapy, have multiple limitations that lead to treatment failure and cancer recurrence. These limitations are related to systemic and local toxicity, while treatment failure and cancer relapse are due to drug resistance and self-renewal, properties of a small population of tumor cells called cancer stem cells (CSCs). These cells are involved in cancer initiation, maintenance, metastasis and recurrence. Therefore, in order to develop efficient treatments that can induce a long-lasting clinical response preventing tumor relapse it is important to develop drugs that can specifically target and eliminate CSCs. Recent identification of surface markers and understanding of molecular feature associated with CSC phenotype helped with the design of effective treatments. In this review we discuss targeting surface biomarkers, signaling pathways that regulate CSCs self-renewal and differentiation, drug-efflux pumps involved in apoptosis resistance, microenvironmental signals that sustain CSCs growth, manipulation of miRNA expression, and induction of CSCs apoptosis and differentiation, with specific aim to hamper CSCs regeneration and cancer relapse. Some of these agents are under evaluation in preclinical and clinical studies, most of them for using in combination with traditional therapies. The combined therapy using conventional anticancer drugs with CSCs-targeting agents, may offer a promising strategy for management and eradication of different types of cancers. PMID:26516409

Mathematical analysis of antiretroviral therapy aimed at HIV-1 eradication or maintenance of low viral loads.

1998-05-07

Motivated by the ability of combinations of antiretroviral agents to sustain viral suppression in HIV-1-infected individuals, we analyse the transient and steady-state behavior of a mathematical model of HIV-1 dynamics in vivo in order to predict whether these drug regimens can eradicate HIV-1 or maintain viral loads at low levels. The model incorporates two cell types (CD4+ T cells and a long-lived pool of cells), two strains of virus (drug-sensitive wild type and drug-resistant mutant) and two types of antiretroviral agents (reverse transcriptase and protease inhibitors). The transient behavior of the cells and virus and the eventual eradication of the virus are determined primarily by the strength of the combination therapy against the mutant strain and the maximum achievable increase in the uninfected CD4+ T cell concentration. We also predict, if the parameters of the model remain constant during therapy, that less intensive maintenance regimens will be unable to maintain low viral loads for extensive periods of time. However, if the reduction in viral load produced by therapy reduces the state of activation of the immune system, the number of cells susceptible for HIV-1 infection may decrease even though total CD4+ T cells increase. Our model predicts that if this occurs strong inductive therapy that reduces viral load followed by weaker maintenance regimes may succeed.

Aims: The aim of this study is to assess the patient compliance to supportive and maintenance periodontal therapy and to determine the reason for noncompliance among young adult patients of Namakkal district, India. Materials and Methods: This was a cross-sectional study conducted on 400 patients who underwent periodontal therapy and subsequently recalled for supportive and maintenance periodontal treatment in the Department of Periodontics, Vivekanandha Dental College for Women, Namakkal. Patients age group 25-35 years and of both gender were equally selected and grouped by occupation and socioeconomic status. According to their compliance with appointments, they are categorized as complete compliance, partially compliance and insufficient or noncompliance. Noncompliance and partially compliance patients were contacted and asked to rate their experience and reason for noncompliance. Results: In this study, 80% of patients showed complete compliance and were regular for supportive periodontal therapy appointments. Women were more regular in maintaining recall appointments than men. Salaried employers showed 84.3% complete compliance, while self-employed personals showed 77% complete compliance and 75% of nonworking personals were regular to the appointment schedule. Noncompliance person has quoted lack of time and forgetting the appointment date as a major reason for missed appointments. Conclusions: This study recommends the need for improvement in communication skills of practitioners and weekend appointment for patient undergoing periodontal maintenance therapy. PMID:25210365

Chronic low back pain causes substantial morbidity and cost to society while disproportionately impacting low-income and minority adults. Several randomized controlled trials show yoga is an effective treatment. However, the comparative effectiveness of yoga and physical therapy, a common mainstream treatment for chronic low back pain, is unknown. This is a randomized controlled trial for 320 predominantly low-income minority adults with chronic low back pain, comparing yoga, physical therapy, and education. Inclusion criteria are adults 18-64 years old with non-specific low back pain lasting ≥ 12 weeks and a self-reported average pain intensity of ≥ 4 on a 0-10 scale. Recruitment takes place at Boston Medical Center, an urban academic safety-net hospital and seven federally qualified community health centers located in diverse neighborhoods. The 52-week study has an initial 12-week Treatment Phase where participants are randomized in a 2:2:1 ratio into i) a standardized weekly hatha yoga class supplemented by home practice; ii) a standardized evidence-based exercise therapy protocol adapted from the Treatment Based Classification method, individually delivered by a physical therapist and supplemented by home practice; and iii) education delivered through a self-care book. Co-primary outcome measures are 12-week pain intensity measured on an 11-point numerical rating scale and back-specific function measured using the modified Roland Morris Disability Questionnaire. In the subsequent 40-week Maintenance Phase, yoga participants are re-randomized in a 1:1 ratio to either structured maintenance yoga classes or home practice only. Physical therapy participants are similarly re-randomized to either five booster sessions or home practice only. Education participants continue to follow recommendations of educational materials. We will also assess cost effectiveness from the perspectives of the individual, insurers, and society using claims databases, electronic medical records, self-report cost data, and study records. Qualitative data from interviews will add subjective detail to complement quantitative data. This trial is registered in ClinicalTrials.gov, with the ID number: NCT01343927.

2016-06-01

This study examined differences in opioid agonist therapy (OAT) utilization among Medicaid-enrolled adults receiving public-sector opioid use disorder treatment in states with Medicaid coverage of methadone maintenance, states with block grant funding only, and states without public coverage of methadone. Person-level treatment admission data, which included information on reason for treatment and use of OAT from 36 states were linked to state-level Medicaid policies collected in a 50-state survey. Probabilities of OAT use among Medicaid enrollees in opioid addiction treatment were calculated, with adjustment for demographic characteristics and patterns of substance use. In adjusted analysis, 45.0% of Medicaid-enrolled individuals in opioid addiction treatment in states with Medicaid coverage for methadone maintenance used OAT, compared with 30.1% in states with block grant coverage only and 17.0% in states with no coverage. Differences were widest in nonintensive outpatient settings. Medicaid methadone maintenance coverage is critical for encouraging OAT among individuals with opioid use disorders.

The Role of Homework and Skill Acquisition in the Outcome of Group Cognitive Therapy for Depression - Republished Article.

Neimeyer, Robert A; Feixas, Guillem

2016-09-01

Despite the crucial role typically accorded to between-session self-help assignments in cognitive therapy of depression, the actual impact of homework assignment on therapy outcome has received little empirical attention. The present study evaluated the effect of homework by assigning 63 carefully diagnosed unipolar depressives to one of two otherwise identical 10-week cognitive therapy conditions, only one of which utilized weekly homework assignments. As predicted, assignment to the homework condition predicted more substantial improvement in symptomatic features of depression as rated by an independent clinician at therapy termination, although this effect was not maintained at six month follow-up. However, a post-therapy assessment of skill acquisition in completing the core cognitive restructuring technique did predict self-rated maintenance of treatment gains six months later, irrespective of the treatment condition to which the subject had been assigned. Taken together, these findings reinforce the value of homework in improving treatment response during the active treatment phase of cognitive therapy for depression, and the importance of skill acquisition in promoting maintenance of treatment gams once therapy has ended.

Single maintenance and reliever therapy (SMART) of asthma: a critical appraisal.

PubMed

Chapman, Kenneth R; Barnes, Neil C; Greening, Andrew P; Jones, Paul W; Pedersen, S

2010-08-01

The use of a combination inhaler containing budesonide and formoterol as both maintenance and quick relief therapy (SMART) has been recommended as an improved method of using inhaled corticosteroid/long-acting beta agonist (ICS/LABA) therapy. Published double-blind trials show that budesonide/formoterol therapy delivered in SMART fashion achieves better asthma outcomes than budesonide monotherapy or lower doses of budesonide/formoterol therapy delivered in constant dosage. Attempts to compare budesonide/formoterol SMART therapy with regular combination ICS/LABA dosing using other compounds have been confounded by a lack of blinding and unspecified dose adjustment strategies. The asthma control outcomes in SMART-treated patients are poor; it has been reported that only 17.1% of SMART-treated patients are controlled. In seven trials of 6-12 months duration, patients using SMART have used quick reliever daily (weighted average 0.92 inhalations/day), have awakened with asthma symptoms once every 7-10 days (weighted average 11.5% of nights), have suffered asthma symptoms more than half of days (weighted average 54.0% of days) and have had a severe exacerbation rate of one in five patients per year (weighted average 0.22 severe exacerbations/patient/year). These poor outcomes may reflect the recruitment of a skewed patient population. Although improvement from baseline has been attributed to these patients receiving additional ICS therapy at pivotal times, electronic monitoring has not been used to test this hypothesis nor the equally plausible hypothesis that patients who are non-compliant with maintenance medication have used budesonide/formoterol as needed for self-treatment of exacerbations. Although the long-term consequences of SMART therapy have not been studied, its use over 1 year has been associated with significant increases in sputum and biopsy eosinophilia. At present, there is no evidence that better asthma treatment outcomes can be obtained by moment-to-moment symptom-driven use of ICS/LABA therapy than conventional physician-monitored and adjusted ICS/LABA therapy.

The purpose of this study was to compare anxiety, depression, and stress between mothers of children during maintenance treatment for acute lymphoblastic leukemia (ALL) and matched controls. Twenty-six mothers were recruited from the hematology unit at a children's hospital, and 26 mothers were recruited from the community. Participants were matched to their child's age and gender. Mothers completed the Hospital Anxiety and Depression Scale, the Perceived Stress Sale, and collected salivary cortisol 4 times a day for 3 consecutive days. Compared with mothers of healthy children, anxiety scores did not differ (P=.10), but depression scores were higher (P=.003) in mothers of children with ALL. More mothers in the ALL group scored above the cutoff of 7 indicating clinical anxiety (46%) and depressive symptoms (27%). A trend toward increased stress was found in mothers in the ALL group. No difference was found in overall daily cortisol (area under the curve), daily decrease in cortisol (slope), and cortisol awakening response. Mothers of children with ALL experienced emotional symptoms many months after the initial diagnosis.

Patients undergoing maintenance hemodialysis develop both structural and functional cardiovascular abnormalities. Despite improvement of dialysis technology, cardiovascular mortality of this population remains high. The pathophysiological mechanisms of these changes are complex and not well understood. It has been postulated that several non-traditional, uremic-related risk factors, especially the long-term uremic state, which may affect the cardiovascular system. There are many cardiovascular changes that occur in chronic kidney disease including left ventricular hypertrophy, myocardial fibrosis, microvascular disease, accelerated atherosclerosis and arteriosclerosis. These structural and functional changes in patients receiving chronic dialysis make them more susceptible to myocardial ischemia. Hemodialysis itself may adversely affect the cardiovascular system due to non-physiologic fluid removal, leading to hemodynamic instability and initiation of systemic inflammation. In the past decade there has been growing awareness that pathophysiological mechanisms cause cardiovascular dysfunction in patients on chronic dialysis, and there are now pharmacological and non-pharmacological therapies that may improve the poor quality of life and high mortality rate that these patients experience.

A means for developing a space shuttle maintenance program which will be acceptable to the development centers, the operators (KSC and AF), and the manufacturer is presented. The general organization and decision processes for determining the essential scheduled maintenance requirements for the space shuttle orbiter are outlined. The development of initial scheduled maintenance programs is discussed. The remaining maintenance, that is non-scheduled or non-routine maintenance, is directed by the findings of the scheduled maintenance program and the normal operation of the shuttle. The remaining maintenance consists of maintenance actions to correct discrepancies noted during scheduled maintenance tasks, nonscheduled maintenance, normal operation, or condition monitoring.

[No best treatment for severe outbreaks: Maintenance, the key in colitis].

PubMed

Sicilia, Beatriz

2011-12-01

Several drugs are currently available to maintain remission in patients who have responded after one or other type of induction therapy, depending on the initial severity of the outbreak. Salicylates are the drugs of choice to maintain remission after a mild-to-moderate outbreak controlled by salicylates or oral corticosteroids. To maintain remission after a severe outbreak or in patients with corticosteroid dependence or resistance, thiopurines are the drugs of choice. In patients who have failed to respond to thiopurines and in those with thiopurine intolerance, biological agents, mainly infliximab, can be used to maintain remission in patients after induction therapy with infliximab for a severe outbreak. However, these scenarios may not reflect reality of gastroenterologists' daily clinical practice. Treatment will therefore be based on the patient's individual characteristics (age, clinical course, previous treatment, adverse effects and personal preferences) as well as the physician's medical art.

With the advent of new disease-modifying drugs, the treatment of multiple sclerosis is becoming increasingly complex. Using consensus statements is therefore advisable. The present consensus statement, which was drawn up by the Spanish Society of Neurology's study group for demyelinating diseases, updates previous consensus statements on the disease. The present study lists the medications currently approved for multiple sclerosis and their official indications, and analyses such treatment-related aspects as activity, early treatment, maintenance, follow-up, treatment failure, changes in medication, and special therapeutic situations. This consensus statement includes treatment recommendations for a wide range of demyelinating diseases, from isolated demyelinating syndromes to the different forms of multiple sclerosis, as well as recommendations for initial therapy and changes in drug medication, and additional comments on induction and combined therapy and practical aspects of the use of these drugs.

1985-09-01

The effect of a synthetic somatostatin analog was studied in a patient with severe secretory diarrhea due to pancreatic cholera syndrome. Basal intestinal perfusion studies indicated an absence of water and sodium absorption, and active chloride secretion in the small bowel. Intravenous administration of the somatostatin analog (1 microgram/kg.h) changed zero net water movement to absorption (122 mL/30 cm of the jejunum per hour). Chloride secretion changed to absorption (5.0 to 7.9 meq/30 cm.h), and plasma vasoactive intestinal polypeptide concentration was reduced from 330 to 45 pmol/L (normal, less than 51). When the analog was given subcutaneously, 100 micrograms twice daily, stool weight decreased, and plasma vasoactive intestinal polypeptide concentration fell toward the normal range (67 pmol/L). Plasma concentration of pancreatic polypeptide was initially elevated and dropped during intravenous infusion of somatostatin analog but returned to baseline on maintenance therapy with the analog delivered subcutaneously. The patient has not had further diarrhea during 9 months of therapy.

Evidence and evidence gaps of laryngeal cancer surgery

Wiegand, Susanne

2016-01-01

Surgical treatment of laryngeal cancer has been established for decades. In addition to total laryngectomy, which was first performed in 1873, a large number or organ preservation surgical techniques, like open partial laryngectomy, transoral laser microsurgery, and transoral robotic surgery have been developed. Studies on laryngeal cancer surgery are mainly retrospective case series and cohort studies. The evolution of chemoradiation protocols and their analysis in prospective randomized trials have led to an increasing acceptance of non-surgical treatment procedures. In addition to an improvement of prognosis, in recent years the preservation of function and maintenance of life quality after primary therapy of laryngeal cancer has increasingly become the focus of therapy planning. Significant late toxicity after chemoradiation has been identified as an important issue. This leads to a reassessment of surgical concepts and initiation of studies on laryngeal cancer surgery which was additionally stimulated by the advent of transoral robotic surgery in the US. Improving the evidence base of laryngeal cancer surgery by successful establishment of surgical trials should be the future goal. PMID:28025603

The role of reamberin, a succinate-containing infusion preparation in correlation of pulmonary metabolic and respiratory disturbances in patients with obstetric puerperal sepsis was estimated. The prospective randomized study enrolled 43 patients with puerperal obstetric sepsis complicated by polyorganic deficiency (SOFA 8-10). Nineteen patients of the 1st group and 24 patients of the 2nd group were additionally treated with reamberin in a dose of 800 ml/day for 8 days. The venous and arterial difference by glucose, lactate, pyruvate, diene conjugates, malondialdehyde and ceruloplasmin was investigated. The blood gases were determined with the Ciba Corning 45 apparatus. Lower metabolic activity of the lungs with prevalence of the glucose anaerobic metabolism and lower activity of the intrapulmonary antioxidant protection were observed in the patients with obstetric sepsis. The use of reamberin in the complex therapy of obstetric sepsis promoted maintenance of the initial balance and anaeroibic and aerobic pulmonary metabolism, thus providing shorter terms of the decompensation and recovery of the lungs respiratory function.

2007-11-18

Insomnia is defined as difficulty with the initiation, maintenance, duration, or quality of sleep that results in the impairment of daytime functioning, despite adequate opportunity and circumstances for sleep. In most countries approximately every third inhabitant has insomnia. Insomnia can be classified as primary and secondary. The pathogenesis of primary insomnia is unknown, but available evidence suggests a state of hyperarousal. Insomnia secondary to other causes is more common than primary insomnia. Cerebral hypoperfusion can be the cause of insomnia in some cases. In such patients the cerebral blood flow should be improved using parenteral vascular therapy. If insomnia persists despite treatment, then therapy for primary insomnia should be instituted using benzodiazepine-receptor agonists such as Zolpidem, Zopiclone, or Zaleplon. In those cases Midazolam cannot be used for the treatment of insomnia due to its marked negative effect on cerebral blood flow. In Hungary there is a need to organize multidisciplinary Insomnia Clinics because insomnia is more than a disease, it is a public health problem in this century.

Asthma and allergic diseases continue to increase in prevalence, creating a financial burden on the health care system and affecting the quality of life for those who have these diseases. Many intrinsic and extrinsic factors are involved in the initiation and maintenance of the allergic response. Cytokines are proteins with growth, differentiation, and activation functions that regulate and direct the nature of immune responses. clinicaltrials.gov and PubMed. Relevant clinical trials and recent basic science studies were chosen for discussion. Many cytokines have been implicated in the development and perpetuation of the allergic response. Biologics have been and are continuing to be developed that target these molecules for use in patients with asthma and atopic dermatitis where standard treatment options fail. The current state of cytokine-targeting therapies is discussed. This review focused on cytokines involved in the allergic response with an emphasis on those for which therapies are being or have been developed.

RecA Inhibitors Potentiate Antibiotic Activity and Block Evolution of Antibiotic Resistance.

PubMed

Alam, Md Kausar; Alhhazmi, Areej; DeCoteau, John F; Luo, Yu; Geyer, C Ronald

2016-03-17

Antibiotic resistance arises from the maintenance of resistance mutations or genes acquired from the acquisition of adaptive de novo mutations or the transfer of resistance genes. Antibiotic resistance is acquired in response to antibiotic therapy by activating SOS-mediated DNA repair and mutagenesis and horizontal gene transfer pathways. Initiation of the SOS pathway promotes activation of RecA, inactivation of LexA repressor, and induction of SOS genes. Here, we have identified and characterized phthalocyanine tetrasulfonic acid RecA inhibitors that block antibiotic-induced activation of the SOS response. These inhibitors potentiate the activity of bactericidal antibiotics, including members of the quinolone, β-lactam, and aminoglycoside families in both Gram-negative and Gram-positive bacteria. They reduce the ability of bacteria to acquire antibiotic resistance mutations and to transfer mobile genetic elements conferring resistance. This study highlights the advantage of including RecA inhibitors in bactericidal antibiotic therapies and provides a new strategy for prolonging antibiotic shelf life. Copyright © 2016 Elsevier Ltd.

Crohns disease and ulcerative colitis are chronic inflammatory diseases of the gastrointestinal tract. Both can be treated with medications that induce and maintain remission. The choice of medication is influenced by the balance between drug potency and potential side-effects, previous response to treatment, and the presence of extraintestinal manifestations or complications. After remission has been achieved, the goal of treatment is to maintain the symptom-free status. 5-aminosalicylic acid derivatives have efficacy for maintenance of remission in patients with distal disease. Thiopurines are recommended for the long-term therapy. For the patients who do not have a response to immunosuppressive therapy or cannot tolerate it, anti-TNF-α agents are gradually being adopted. Effective in the remission maintenance are thiopurines, infliximab and adalimumab.

Behaviour change interventions are effective in supporting individuals in achieving temporary behaviour change. Behaviour change maintenance, however, is rarely attained. The aim of this review was to identify and synthesise current theoretical explanations for behaviour change maintenance to inform future research and practice. Potentially relevant theories were identified through systematic searches of electronic databases (Ovid MEDLINE, Embase, PsycINFO). In addition, an existing database of 80 theories was searched, and 25 theory experts were consulted. Theories were included if they formulated hypotheses about behaviour change maintenance. Included theories were synthesised thematically to ascertain overarching explanations for behaviour change maintenance. Initial theoretical themes were cross-validated. One hundred and seventeen behaviour theories were identified, of which 100 met the inclusion criteria. Five overarching, interconnected themes representing theoretical explanations for behaviour change maintenance emerged. Theoretical explanations of behaviour change maintenance focus on the differential nature and role of motives, self-regulation, resources (psychological and physical), habits, and environmental and social influences from initiation to maintenance. There are distinct patterns of theoretical explanations for behaviour change and for behaviour change maintenance. The findings from this review can guide the development and evaluation of interventions promoting maintenance of health behaviours and help in the development of an integrated theory of behaviour change maintenance.

Many solid cancers display cellular hierarchies with self-renewing, tumorigenic stemlike cells, or cancer-initiating cells (CICs) at the apex. Whereas CICs often exhibit relative resistance to conventional cancer therapies, they also receive critical maintenance cues from supportive stromal elements that also respond to cytotoxic therapies. To interrogate the interplay between chemotherapy and CICs, we investigated cellular heterogeneity in human colorectal cancers. Colorectal CICs were resistant to conventional chemotherapy in cell-autonomous assays, but CIC chemoresistance was also increased by cancer-associated fibroblasts (CAFs). Comparative analysis of matched colorectal cancer specimens from patients before and after cytotoxic treatment revealed a significant increase in CAFs. Chemotherapy-treated human CAFs promoted CIC self-renewal and in vivo tumor growth associated with increased secretion of specific cytokines and chemokines, including interleukin-17A (IL-17A). Exogenous IL-17A increased CIC self-renewal and invasion, and targeting IL-17A signaling impaired CIC growth. Notably, IL-17A was overexpressed by colorectal CAFs in response to chemotherapy with expression validated directly in patient-derived specimens without culture. These data suggest that chemotherapy induces remodeling of the tumor microenvironment to support the tumor cellular hierarchy through secreted factors. Incorporating simultaneous disruption of CIC mechanisms and interplay with the tumor microenvironment could optimize therapeutic targeting of cancer. PMID:24323355

Transplant patients on tacrolimus therapy exhibit a reduced glomerular filtration rate (GFR). The type of graft and immune treatment protocol may influence the extent and reversibility of this side effect. The present single-center study is conducted in 48 nonuremic type 1 diabetic recipients of an intraportal islet-cell graft under maintenance immunosuppression (IS) with tacrolimus and mycophenolate mofetil. Estimated GFR (eGFR) and albuminuria were followed up to 5 years posttransplantation. Mean eGFR values decreased by 19 mL/min/1.73 m after 1 to 2 weeks of IS (P<0.0001) and then remained stable throughout the complete treatment period. The decrease was related to predose trough tacrolimus concentrations or doses and disappeared upon its discontinuation; it was also associated with the presence of albuminuria at the time of transplantation. Tacrolimus treatment resulted in a reduction of albuminuria; its discontinuation restored albuminuria to the initial levels. The use of tacrolimus in our islet-cell transplant protocol caused an initial 20% reduction in eGFR, which was reversible following its discontinuation, at least within the 5-year follow-up period. The associated reduction in albuminuria was also reversible, compatible with a tacrolimus-induced preglomerular vasoconstriction. These observations support further use of our tacrolimus regimen in this patient population.

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.

Recently, macroautophagy/autophagy has emerged as a promising target in various types of solid tumor treatment. However, the impact of autophagy on acute myeloid leukemia (AML) maintenance and the validity of autophagy as a viable target in AML therapy remain unclear. Here we show that Kmt2a/Mll-Mllt3/Af9 AML (MA9-AML) cells have high autophagy flux compared with normal bone marrow cells, but autophagy-specific targeting, either through Rb1cc1-disruption to abolish autophagy initiation, or via Atg5-disruption to prevent phagophore (the autophagosome precursor) membrane elongation, does not affect the growth or survival of MA9-AML cells, either in vitro or in vivo. Mechanistically, neither Atg5 nor Rb1cc1 disruption impairs endolysosome formation or survival signaling pathways. The autophagy inhibitor chloroquine shows autophagy-independent anti-leukemic effects in vitro but has no efficacy in vivo likely due to limited achievable drug efficacy in blood. Further, vesicular exocytosis appears to mediate chloroquine resistance in AML cells, and exocytotic inhibition significantly enhances the anti-leukemic effect of chloroquine. Thus, chloroquine can induce leukemia cell death in vitro in an autophagy-independent manner but with inadequate efficacy in vivo, and vesicular exocytosis is a possible mechanism of chloroquine resistance in MA9-AML. This study also reveals that autophagy-specific targeting is unlikely to benefit MA9-AML therapy.

Despite conducting wide-ranging of pharmacotherapy for bipolar adolescents, many of them are showing a deficit in functioning with high relapse rate. The aim of the current study was to develop a manual and investigate the efficacy of group cognitive-behavioral therapy (G-CBT) for female bipolar adolescents. During the first qualitative phase of a mixed-methods study, a manual of G-CBT was developed. Then, 32 female bipolar adolescents aged 12-19 years old, receiving usual maintenance medications (UMM), were selected. Participants were randomized to the control (UMM) and intervention group (5, 2 h weekly sessions based on G-CBT manual with UMM). The parents in intervention group participated in three parallel sessions. All participants filled the following questionnaires before 1, 3, and 6 months after the initiation of the study: Young Mania Rating Scale, Children Depression Inventory and Global Assessment of Functioning. The results were analyzed using SPSS 21 software. The concurrent qualitative phase was analyzed through thematic analysis. The results showed no significant differences in all questionnaires' scores through intervention and follow-up sessions ( P > 0.05). However, using cutoff point of CDI, G-CBT was effective for intervention group (relapse rate: 25% vs. 44.4%). Two themes were extracted from the second qualitative phase: emotion recognition and emotion regulation, especially in anger control. The results showed that the addition of G-CBT to UMM leads to decrease in the depressive scores but has no effect on manic symptoms and relapse rate.

The aim of this study is to assess the incidence, risk factors, and outcome of biopsy-proven transformation in follicular lymphoma (FL) patients in the rituximab era. Transformation was analyzed in 1233 patients with initially diagnosed FL grades 1-3A, identified between 2002 and 2012 in the prospectively maintained Czech Lymphoma Study Group database. Only patients with histologically proven transformation (HT) were included. HT occurred in 58 cases at a median of 3.0 years from the initial FL diagnosis; the HT rate was 4% at 5 years. Transformation occurred most frequently at the first relapse (84% patients). Median OS from the HT was 2.5 years (95% CI 0.4-4.6) and 6-year OS with HT was shorter compared to all FLs (60 vs. 83.9%; 95% CI). A bulky tumor (≥ 10 cm), increased lactate dehydrogenase, age ≥ 60 years, and International Prognostic Index (intermediate/high risk), but not Follicular Lymphoma International Prognostic Index, were associated with transformation (p < 0.05). In the first line, 70% of patients received rituximab (including 36% rituximab maintenance), 57% CHOP-like regimens, and 2.6% of patients were treated with fludarabine-based therapy, whereas 11% of patients were watched only. The patients treated with R-CHOP in the first line (n = 591) showed the transformation rate at 5 years of 4.23% (95% CI 2.52-5.93); subsequent rituximab maintenance (n = 276) vs. observation (n = 153) was associated with a lower transformation rate (p.033; HR 3.29; CI 1.10-9.82). The transformation rate seems to be lower than in previous series, which may be influenced by broad use of rituximab, but prognosis of HT developed during therapy continues to be poor.

To determine whether the diameter of intrahepatic and extrahepatic bile ducts and pancreatic ducts in patients on methadone maintenance therapy is increased when compared with control subjects. Between January 1, 2000 and March 15, 2013, a total of 97 patients (mean age 49.9, range 22-79, 65 male, 32 female) were identified who were receiving chronic methadone maintenance therapy (MMT) when they underwent imaging with abdominal MRI or a contrast-enhanced abdominopelvic CT. A group of 97 consecutive non-MMT control patients (mean age 51.4, range 21-86, 45 male, 52 female) who underwent imaging with abdominal MRI or contrast-enhanced abdominopelvic CT were identified. Patients with known pancreaticobiliary pathology that may confound biliary ductal measurements were excluded. Blinded interpretation was performed, documenting the diameters of the intrahepatic and extrahepatic bile ducts and pancreatic ducts. Descriptive statistics were performed. Patients on MMT demonstrated increased bile duct diameter, with an average increase in duct diameter of 2.39 mm for the common bile duct (p < 0.001; 95% CI 1.88-2.90 mm), 1.43 mm for the intrahepatic bile ducts (p < 0.001; 95% CI 1.12-1.74 mm), and 0.90 mm for the pancreatic duct (p < 0.001; 95% CI 0.64-1.16 mm). No statistically significant correlation was found between ductal diameters and the daily dose of methadone. Patients on methadone maintenance therapy demonstrate significantly increased intra- and extrahepatic bile duct and pancreatic duct diameter when compared with controls. There was no correlation between the dose of methadone and ductal diameter.

Therapeutic interventions can be classified into two distinct approaches: abstinent and maintenance method. Currently, there are no clear criteria for referring addicted patients to one of these modalities. We aimed to compare the personality characteristics of individuals with addiction who attended narcotics anonymous sessions with those who received methadone maintenance therapy. This was a cross- sectional study. The participants were NA members and patients who were undergoing methadone maintenance treatment in outpatient clinics. Using the randomized cluster sampling method, 200 individuals with opioid dependence were selected (each group 100 persons). Data were collected through a demographic questionnaire and the five-factor personality inventory (NEO-FFI). Comparison of the mean scores of NEO-PPI in the two groups was performed by independent t test, and qualitative variables were compared using the Chi-square test. We found a significant difference between the MMT and NA groups with respect to neuroticism, extroversion, and agreeableness. No significant difference was found in the subscales of conscientious and openness. People who regularly attended the NA sessions had lower neuroticism and higher agreeableness than patients who were under the maintenance modality. Whether this is the cause or effect of attending NA sessions requires future large-scale cohort studies.

Lung cancer first line treatment has been directed from the non-specific cytotoxic doublet chemotherapy to the molecular targeted. The major limitation of the targeted therapies still remains the small number of patients positive to gene mutations. Furthermore, the differentiation between second line and maintenance therapy has not been fully clarified and differs in the clinical practice between cancer centers. The authors present a segregation between maintenance treatment and second line and present a possible definition for the term “maintenance” treatment. In addition, cancer cell evolution induces mutations and therefore either targeted therapies or non-specific chemotherapy drugs in many patients become ineffective. In the present work pathways such as epidermal growth factor, anaplastic lymphoma kinase, met proto-oncogene and PI3K are extensively presented and correlated with current chemotherapy treatment. Future, perspectives for targeted treatment are presented based on the current publications and ongoing clinical trials. PMID:24312144

Chronic inflammatory demyelinating polyneuropathy (CIDP) is a rare complication of Crohn's disease (CD), and it is uncertain whether it is associated with CD itself or with its treatment. We describe a case of CIDP-like neuropathy as an initial symptom of CD. The neurologic symptoms of the patient which responded partially to intravenous immunoglobulin (IVIG) recovered after resection of the appendiceal CD. A 17-year-old male had experienced three separate attacks of motor weakness and paresthesia of all four extremities over a period of 7 months. The electrophysiologic findings revealed a demyelinating sensory-motor polyneuropathy which was compatible with CIDP. However, repeated intravenous IVIG (2 g/kg) treatment gave only a partial response. Four days after the last discharge, he was diagnosed as appendiceal CD after surgical resection of a periappendiceal abscess. His neurologic symptoms and electrophysiologic findings recovered without any maintenance therapy. CIDP-like neuropathy can be an initial presentation of CD, and recovery of the CIDP symptoms may result from resection of the CD. Clinicians should be aware of the possibility of CD in patients with intractable CIDP symptoms.

Defining the genetic drivers of cancer progression is a key in understanding disease biology and developing effective targeted therapies. Chromosome rearrangements are a common feature of human malignancies, but whether they represent bona fide cancer drivers and therapeutically actionable targets, requires functional testing. Here, we describe the generation of transgenic, inducible CRISPR-based mouse systems to engineer and study recurrent colon cancer-associated EIF3E–RSPO2 and PTPRK–RSPO3 chromosome rearrangements in vivo. We show that both Rspo2 and Rspo3 fusion events are sufficient to initiate hyperplasia and tumour development in vivo, without additional cooperating genetic events. Rspo-fusion tumours are entirely Wnt-dependent, as treatment with an inhibitor of Wnt secretion, LGK974, drives rapid tumour clearance from the intestinal mucosa without effects on normal intestinal crypts. Altogether, our study provides direct evidence that endogenous Rspo2 and Rspo3 chromosome rearrangements can initiate and maintain tumour development, and indicate a viable therapeutic window for LGK974 treatment of RSPO-fusion cancers.

Computer-assisted behavioral treatments hold promise for enhancing access to and reducing costs of treatments for substance use disorders. This study assessed the efficacy of a computer-assisted version of an efficacious, multicomponent treatment for cannabis use disorders (CUD), i.e., motivational enhancement therapy, cognitive-behavioral therapy, and abstinence-based contingency-management (MET/CBT/CM). An initial cost comparison was also performed. Seventy-five adult participants, 59% African Americans, seeking treatment for CUD received either, MET only (BRIEF), therapist-delivered MET/CBT/CM (THERAPIST), or computer-delivered MET/CBT/CM (COMPUTER). During treatment, the THERAPIST and COMPUTER conditions engendered longer durations of continuous cannabis abstinence than BRIEF (p < .05), but did not differ from each other. Abstinence rates and reduction in days of use over time were maintained in COMPUTER at least as well as in THERAPIST. COMPUTER averaged approximately $130 (p < .05) less per case than THERAPIST in therapist costs, which offset most of the costs of CM. Results add to promising findings that illustrate potential for computer-assisted delivery methods to enhance access to evidence-based care, reduce costs, and possibly improve outcomes. The observed maintenance effects and the cost findings require replication in larger clinical trials. PMID:25938629

The aim of the present case report was to investigate the effects of a physiotherapy program combined with sirolimus in a child patient with upper extremity edema and joint limitation due to low-flow vascular malformation. This case report included an 11-year-old male patient (26 kg, 130 cm) diagnosed with congenital lymphovascular malformation on the left and right chest. The patient, who had edema on the upper left extremity and experienced joint limitations, was administered complete decongestive therapy (CDT) and manual therapy in combination with sirolimus. Physiotherapy included a total of 24 sessions, 3 sessions a week for 8 weeks. Following the physiotherapy, the patient was assigned to a home therapy program, and then the maintenance phase of the CDT was initiated. Evaluations were carried out at baseline, at the end of week 8, and after 12 months. Following the physiotherapy program combined with sirolimus, a decrease in extremity volume, an increase in joint movement range, and an improvement in disease-related complaints were observed. Physiotherapy methods combined with sirolimus may be an effective treatment method in patients with vascular malformations. However, further studies with larger sample size are warranted.

The effect of folic acid supplements on 6-mercaptopurine remission maintenance therapy in lymphoblastic leukaemia (ALL) was investigated in a retrospective longitudinal study of 10 children. Red cell concentrations of 6-thioguanine nucleotide, a cytotoxic metabolite of 6-mercaptopurine, were measured and the peripheral neutrophil count was used as an index of myelosuppression. During the control period of the study there were significant correlations between 6-mercaptopurine dose and 6-thioguanine nucleotide concentration (rs = 0.59, P less than 0.0005) and between 6-thioguanine nucleotide concentration and the peripheral neutrophil count at 14 days (rs = 0.58, P less than 0.0005). These relationships were absent when the same children were subsequently taking folate supplements. Also when taking folate supplements the children tolerated significantly more 6-mercaptopurine (P less than 0.005) for a significantly longer time (P less than 0.005) before neutropenia developed. There was no significant difference in red cell 6-thioguanine nucleotide concentration in the absence and presence of folate supplements. These findings suggest that folate supplements may interfere with remission maintenance therapy in ALL. PMID:3456241

Abstract The aim of this study was to investigate the influence of daily 6-mercaptopurine (6-MP) and low-dose weekly methotrexate (MTX) combination treatment and methylenetetrahydrofolate reductase (MTHFR) haplotypes on toxicity during maintenance therapy in Japanese childhood acute lymphoblastic leukemia (ALL). We retrospectively analyzed the MTHFR C677T and A1298C polymorphisms and influence of haplotypes on toxicity in 73 patients. Patients with the MTHFR 677TT and 677CT + 1298AC were associated with severe liver toxicity (p = 0.014, odds ratio [OR] = 3.82, 95% confidence interval [CI] = 1.27-11.46) and more rapid onset of liver toxicity (p = 0.010). Patients with MTHFR 677TT and 677CT + 1298AC were associated with lower frequency of 6-MP and MTX dose reduction due to leukopenia (p < 0.05). No difference was observed in average drug doses in the MTHFR genotypes. In conclusion, the MTHFR C677T and A1298C haplotypes might be useful for monitoring adverse effects in childhood ALL maintenance therapy in Japanese patients.

Objective Electroconvulsive therapy (ECT) can be given as the form of acute, continuation or maintenance ECT according to the process of administration. We report our 7 years’ observation with acute and maintenance ECT in a university hospital in Turkey. Methods The medical records of the hospitalized patients treated with acute or maintenance ECT between the years 2007 and 2013 was retrospectively analyzed. The sociodemographic characteristics, diagnosis, data of ECT and the co-administered psychotropic drugs were recorded. The frequency of ECT was calculated by identifying the total number of the hospitalized patients during the study period from the hospital records. Results A total number of 1,432 female and 1,141 male patients hospitalized in a period of 7 years, with a total number of 111 patients treated with ECT. The ratio of ECT was 4%, maintenance/acute ECT 11%. For acute ECT, affective disorders (65.3%) and psychotic disorders (21.6%) were among the leading diagnoses. Maintenance ECT, the diagnosis was; 6 affective disorders, 4 psychotic disorders and 1 obsessive compulsive disorder. There was a significant difference between the patients receiving acute and maintenance ECT in terms of age, duration of illness, and number of previous hospitalizations and ECTs. Conclusion The percentage of patients treated with acute ECT is lower in our institution than that in many other institutions from our country. Acute and maintenance ECT should be considered as an important treatment option particularly for patients with long disease duration, a high number of hospitalizations and a history of benefiting from previous ECTs.

2012-07-01

The combination of an inhaled corticosteroid (ICS), budesonide, and a rapid long-acting β(2)-agonist (LABA), formoterol, in a single inhaler for use as maintenance and reliever therapy (Symbicort Turbuhaler SMART™) effectively achieves a high level of asthma control and reduces exacerbations and asthma-related hospitalizations. The COSMOS study, a multinational, 12-month study (N = 2143), compared budesonide/formoterol maintenance and reliever therapy with salmeterol/fluticasone propionate plus as-needed salbutamol, allowing physicians to modify maintenance doses of both combinations according to routine clinical practice. The aim of this post hoc sub-group analysis of the COSMOS study is to provide focused data on budesonide/formoterol maintenance and reliever therapy compared with salmeterol/fluticasone propionate plus as-needed salbutamol in patients (aged ≥16 years) enrolled across Asian countries, specifically China, Korea, Taiwan and Thailand. This sub-analysis of the COSMOS study concerns all 404 randomized patients ≥16 years of age (mean forced expiratory volume in 1 second [FEV(1)] 69.1%) who were recruited from Asian countries. Patients received either budesonide/formoterol (Symbicort Turbuhaler SMART™, n = 198), starting dose 160 mg/4.5 mg two inhalations twice daily (bid) [plus additional as-needed inhalations], or salmeterol/fluticasone propionate (Seretide(®) Diskus(®), n = 206), starting dose 50 mg/250 mg bid (plus salbutamol [Ventolin(®)] as needed). Maintenance doses could be titrated by clinicians after the first 4 weeks (budesonide/formoterol maintenance plus as needed, n = 198; salmeterol/fluticasone propionate plus salbutamol, n = 206). To allow for free adjustment in maintenance doses in both arms, the trial was performed open-label; maintenance doses could be titrated by clinicians after the first 4 weeks. The time to first severe exacerbation (defined as deterioration in asthma resulting in hospitalization/emergency room treatment, oral corticosteroids for ≥3 days or unscheduled visit leading to treatment change) was the primary variable. The time to first severe exacerbation was prolonged in patients using maintenance plus as-needed budesonide/formoterol compared with salmeterol/fluticasone propionate plus salbutamol (log-rank p = 0.024). The risk of a first exacerbation was reduced by 44% (hazard ratio 0.56; 95% confidence interval [CI] 0.32, 0.95; p = 0.033) in patients using the adjusted budesonide/formoterol regimen versus titrated salmeterol/fluticasone propionate. The overall exacerbation rates were 0.16 versus 0.26 events/patient-year, respectively, with a 38% reduction (rate ratio 0.62/patient/year; 95% CI 0.41, 0.94; p = 0.024) in favour of the budesonide/formoterol regimen. Compared with baseline, both regimens provided clinically relevant improvements in asthma control, quality of life and FEV(1); no statistically significant differences between the treatment groups were observed. Mean adjusted (standard deviation) ICS dose (expressed as beclomethasone dose equivalents) during treatment, including as-needed budesonide doses, was 944 (281) and 1034 (394) μg/day, respectively, in patients using maintenance plus as-needed budesonide/formoterol compared with salmeterol/fluticasone propionate. In patients (aged ≥16 years) enrolled from Asian countries as part of the COSMOS study, the budesonide/formoterol maintenance and reliever regimen was associated with a lower future risk of exacerbations versus the physicians' free choice of salmeterol/fluticasone propionate dose plus salbutamol. Single inhaler combination treatment with maintenance plus as-needed budesonide/formoterol was also at least as efficacious as salmeterol/fluticasone propionate dose plus salbutamol in improving current asthma control.

Acne is a chronic inflammatory skin disease that involves the pathogenesis of four major factors, such as androgen-induced increased sebum secretion, altered keratinization, colonization of Propionibacterium acnes, and inflammation. Several acne mono-treatment and combination treatment regimens are available and prescribed in the Indian market, ranging from retinoids, benzoyl peroxide (BPO), anti-infectives, and other miscellaneous agents. Although standard guidelines and recommendations overview the management of mild, moderate, and severe acne, relevance and positioning of each category of pharmacotherapy available in Indian market are still unexplained. The present article discusses the available topical and oral acne therapies and the challenges associated with the overall management of acne in India and suggestions and recommendations by the Indian dermatologists. The experts opined that among topical therapies, the combination therapies are preferred over monotherapy due to associated lower efficacy, poor tolerability, safety issues, adverse effects, and emerging bacterial resistance. Retinoids are preferred in comedonal acne and as maintenance therapy. In case of poor response, combination therapies BPO-retinoid or retinoid-antibacterials in papulopustular acne and retinoid-BPO or BPO-antibacterials in pustular-nodular acne are recommended. Oral agents are generally recommended for severe acne. Low-dose retinoids are economical and have better patient acceptance. Antibiotics should be prescribed till the inflammation is clinically visible. Antiandrogen therapy should be given to women with high androgen levels and are added to regimen to regularize the menstrual cycle. In late-onset hyperandrogenism, oral corticosteroids should be used. The experts recommended that an early initiation of therapy is directly proportional to effective therapeutic outcomes and prevent complications. PMID:28794543

Part 2 of the guidelines on responsible opioid prescribing provides the following recommendations for initiating and maintaining chronic opioid therapy of 90 days or longer. 1. A) Comprehensive assessment and documentation is recommended before initiating opioid therapy, including documentation of comprehensive history, general medical condition, psychosocial history, psychiatric status, and substance use history. ( good) B) Despite limited evidence for reliability and accuracy, screening for opioid use is recommended, as it will identify opioid abusers and reduce opioid abuse. ( limited) C) Prescription monitoring programs must be implemented, as they provide data on patterns of prescription usage, reduce prescription drug abuse or doctor shopping. ( good to fair) D) Urine drug testing (UDT) must be implemented from initiation along with subsequent adherence monitoring to decrease prescription drug abuse or illicit drug use when patients are in chronic pain management therapy. ( good) 2. A) Establish appropriate physical diagnosis and psychological diagnosis if available prior to initiating opioid therapy. ( good) B) Caution must be exercised in ordering various imaging and other evaluations, interpretation and communication with the patient, to avoid increased fear, activity restriction, requests for increased opioids, and maladaptive behaviors. ( good) C) Stratify patients into one of the 3 risk categories - low, medium, or high risk. D) A pain management consultation, may assist non-pain physicians, if high-dose opioid therapy is utilized. ( fair) 3. Essential to establish medical necessity prior to initiation or maintenance of opioid therapy. ( good) 4. Establish treatment goals of opioid therapy with regard to pain relief and improvement in function. ( good) 5. A) Long-acting opioids in high doses are recommended only in specific circumstances with severe intractable pain that is not amenable to short-acting or moderate doses of long-acting opioids, as there is no significant difference between long-acting and short-acting opioids for their effectiveness or adverse effects. ( fair) B) The relative and absolute contraindications to opioid use in chronic non-cancer pain must be evaluated including respiratory instability, acute psychiatric instability, uncontrolled suicide risk, active or history of alcohol or substance abuse, confirmed allergy to opioid agents, coadministration of drugs capable of inducing life-limiting drug interaction, concomitant use of benzodiazepines, active diversion of controlled substances, and concomitant use of heavy doses of central nervous system depressants. ( fair to limited) 6. A robust agreement which is followed by all parties is essential in initiating and maintaining opioid therapy as such agreements reduce overuse, misuse, abuse, and diversion. ( fair) 7. A) Once medical necessity is established, opioid therapy may be initiated with low doses and short-acting drugs with appropriate monitoring to provide effective relief and avoid side effects. ( fair for short-term effectiveness, limited for long-term effectiveness) B) Up to 40 mg of morphine equivalent is considered as low dose, 41 to 90 mg of morphine equivalent as a moderate dose, and greater than 91 mg of morphine equivalence as high dose. ( fair) C) In reference to long-acting opioids, titration must be carried out with caution and overdose and misuse must be avoided. ( good) 8. A) Methadone is recommended for use in late stages after failure of other opioid therapy and only by clinicians with specific training in the risks and uses. ( limited) B) Monitoring recommendation for methadone prescription is that an electrocardiogram should be obtained prior to initiation, at 30 days and yearly thereafter. ( fair) 9. In order to reduce prescription drug abuse and doctor shopping, adherence monitoring by UDT and PMDPs provide evidence that is essential to the identification of those patients who are non-compliant or abusing prescription drugs or illicit drugs. ( fair) 10. Constipation must be closely monitored and a bowel regimen be initiated as soon as deemed necessary. ( good) 11. Chronic opioid therapy may be continued, with continuous adherence monitoring, in well-selected populations, in conjunction with or after failure of other modalities of treatments with improvement in physical and functional status and minimal adverse effects. ( fair). The guidelines are based on the best available evidence and do not constitute inflexible treatment recommendations. Due to the changing body of evidence, this document is not intended to be a "standard of care."

Background Mucosal healing is an important therapeutic endpoint in the management of Crohn’s disease (CD) and ulcerative colitis (UC). Limited data exists regarding the comparative efficacy of various therapies in achieving this outcome. Methods We performed a systematic review and meta-analysis of randomized controlled trials (RCT) examining mucosal healing as an endpoint of immunosuppressives, anti-tumor necrosis factor α (anti-TNF) or anti-integrin monoclonal antibody therapy for moderate-to-severe CD or UC. Pooled effect sizes for induction and maintenance of mucosal healing were calculated and pair-wise treatment comparisons evaluated using a Bayesian network meta-analysis. Results A total of 12 RCTs were included in the meta-analysis (CD – 2 induction, 4 maintenance; UC – 8 induction, 5 maintenance). Duration of follow-up was 6–12 weeks for induction and 32–54 weeks for maintenance trials. In CD, anti-TNFs were more effective than placebo for maintaining mucosal healing (28% vs. 1%, Odds ratio (OR) 19.71, 95% confidence interval (CI) 3.51 – 110.84). In UC, anti-TNFs and anti-integrins were more effective than placebo for inducing (45% vs. 30%) and maintaining mucosal healing (33% vs. 18%). In network analysis, adalimumab therapy was inferior to infliximab (OR 0.45, 95% credible interval (CrI) 0.25 – 0.82) and combination infliximab-azathioprine (OR 0.32, 95% CrI 0.12 – 0.84) for inducing mucosal healing in UC. There was no statistically significant pairwise difference between vedolizumab and anti-TNF agents in UC. Conclusion Anti-TNF and anti-integrin biologic agents are effective in inducing mucosal healing in UC with adalimumab being inferior to infliximab or combination therapy. Infliximab and adalimumab were similar in CD. PMID:28326566

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.

Tofacitinib, an oral, small-molecule Janus kinase inhibitor, was shown to have potential efficacy as induction therapy for ulcerative colitis in a phase 2 trial. We further evaluated the efficacy of tofacitinib as induction and maintenance therapy. We conducted three phase 3, randomized, double-blind, placebo-controlled trials of tofacitinib therapy in adults with ulcerative colitis. In the OCTAVE Induction 1 and 2 trials, 598 and 541 patients, respectively, who had moderately to severely active ulcerative colitis despite previous conventional therapy or therapy with a tumor necrosis factor antagonist were randomly assigned to receive induction therapy with tofacitinib (10 mg twice daily) or placebo for 8 weeks. The primary end point was remission at 8 weeks. In the OCTAVE Sustain trial, 593 patients who had a clinical response to induction therapy were randomly assigned to receive maintenance therapy with tofacitinib (either 5 mg or 10 mg twice daily) or placebo for 52 weeks. The primary end point was remission at 52 weeks. In the OCTAVE Induction 1 trial, remission at 8 weeks occurred in 18.5% of the patients in the tofacitinib group versus 8.2% in the placebo group (P=0.007); in the OCTAVE Induction 2 trial, remission occurred in 16.6% versus 3.6% (P<0.001). In the OCTAVE Sustain trial, remission at 52 weeks occurred in 34.3% of the patients in the 5-mg tofacitinib group and 40.6% in the 10-mg tofacitinib group versus 11.1% in the placebo group (P<0.001 for both comparisons with placebo). In the OCTAVE Induction 1 and 2 trials, the rates of overall infection and serious infection were higher with tofacitinib than with placebo. In the OCTAVE Sustain trial, the rate of serious infection was similar across the three treatment groups, and the rates of overall infection and herpes zoster infection were higher with tofacitinib than with placebo. Across all three trials, adjudicated nonmelanoma skin cancer occurred in five patients who received tofacitinib and in one who received placebo, and adjudicated cardiovascular events occurred in five who received tofacitinib and in none who received placebo; as compared with placebo, tofacitinib was associated with increased lipid levels. In patients with moderately to severely active ulcerative colitis, tofacitinib was more effective as induction and maintenance therapy than placebo.

One of the main problems of the drug abusers is drug related attention bias, which causes craving, and as a result drive the drug abusers to take narcotics. Methadone is used as a maintenance treatment for drug abusers. The purpose of this study is evaluation of the effect of Methadone maintenance therapy (MMT) on selective attention and drug related attention bias. This study investigated drug cue-related attention bias and selective attention in 16 methadone-maintained patients before and 45 days after methadone therapy period. Stroop color-word test and addiction Stroop test were used as measurement methods. Results show less reaction time and higher accuracy in Color-Word Stroop Test after MMT and less delay for addict related word in addiction Stroop test. It is concluded that methadone can improve selective attention capability and reduce drug related attention bias.

Bipolar disorder is common, recurrent, often severe and debiliting disorder. All types of bipolar disorder have a common determinant: depressive episode. It is justify to propose a psychotherapy which shown efficacy in depression. Howewer, perturbations in circadian rhythms have been implicated in the genesis of each episode of the illness. Biological circadian dysregulation can be encouraged by alteration of time-givers (Zeitgebers) or occurrence of time-disturbers (Zeitstörers). Addition of social rhythm therapy to interpersonal psychotherapy leads to create a new psychotherapy adaptated to bipolar disorders: InterPersonal and Social Rhythm Therapy (IPSRT). IPSRT, in combinaison with medication, has demonstrated efficacy as a treatment for bipolar disorders. IPSRT combines psychoeducation, behavioral strategy to regularize daily routines and interpersonal psychotherapy which help patients cope better with the multiple psychosocial and relationship problems associated with this chronic disorder. The main issues of this psychotherapy are: to take the history of the patient's illness and review of medication, to help patient for "grief for the lost healthy self" translated in the french version in "acceptance of a long-term medical condition", to give the sick role, to examinate the current relationships and changes proximal to the emergence of mood symptoms in the four problem areas (unresolved grief, interpersonal disputes, role transitions, role déficits), to examinate and increase daily routines and social rhythms. French version of IPSRT called TIPARS (with few differences), a time-limited psychotherapy, in 24 sessions during approximatively 6 months, is conducted in three phases. In the initial phase, the therapist takes a thorough history of previous episodes and their interpersonal context and a review of previous medication, provides psychoeducation, evaluates social rhythms, introduces the Social Rhythm Metric, identifies the patient's main interpersonal problem area, and contractualizes the therapy. In the second phase, the therapist focuses work with patient toward regulating the patient's daily routines as well as resolving the interpersonal problem areas relevant to episodes (mainly interpersonal disputes and role transitions). In the third or terminaison phase, the therapist evaluates efficacy of the therapy, enhances the patient's independent functioning and develops strategies for relapse prevention. The further maintenance phase suggests differents strategies as maintenance therapy or focused intensive interventions on specific topics. Copyright © 2010 L'Encéphale.

A 20-year-old man with Behcet's disease characterized by recurrent arterial aneurysms presented with a new aortic root aneurysm. This patient previously had aneurysms of the coronary arteries and vein, as well as ruptured renal artery aneurysm. Chronic maintenance immunosuppressive therapy was recommended due to the catastrophic nature of the disease, which the patient refused to take. The patient died shortly after admission. This case demonstrates the unique catastrophic natural history of vascular Behcet's disease with recurrent life-threatening arterial events, and this case stresses the therapeutic dilemma of maintenance immunosuppressive therapy in selected patients.

Bracing is an effective therapy for pectus carinatum: interim results.

Pectus Carinatum is a common congenital chest wall malformation. Until recently the mainstay of treatment was surgical remodeling of the deformed chest wall. Initial results suggest that non-operative bracing may be an effective therapy, but the optimal strategy for correction is not known. Herein we report the results of a self-adjustable low profile bracing system worn continuously until the defect is corrected (correction phase), then worn at night (8 h/day) until completion of axial growth (maintenance phase)-the Calgary Protocol. Patients referred to a pediatric surgery chest wall clinic were prospectively asked to join an IRB approved outcomes monitoring study. 124 patients were evaluated from 2007 to 2011, and 98 were prescribed a brace and counseled to follow the protocol. 98 patients consented to follow-up at starting bracing age: 14.4 ± 1.9 years, Tanner stage: 3.6 ± 0.5, protrusion: 2.1 ± 1.0 cm, self-rating of appearance: 2.9 ± 1.1, and exercise tolerance: 4.4 ± 1.1 (1-5 with 5 = normal). 10 patients are in correction phase, and 44 patients have completed correction after 7.0 ± 7.3 months: Tanner stage: 3.8 ± 0.1, protrusion: 0.5 ± 0.6 cm*, appearance: 4.3 ± 0.3* and exercise tolerance 4.6 ± 1.0. Correction occurred more quickly in patients prior to achieving Tanner stage IV (4.2 ± 0.9 months) vs. Tanner stage IV (8.0 ± 7.1 months) at the beginning of bracing. 21 patients completed maintenance bracing after 17.9 ± 19.0 months: Tanner stage: 3.9 ± 0.2, protrusion 0.5 ± 0.7 cm*, appearance: 4.3 ± 0.9*, and exercise tolerance: 4.8 ± 1.4. Average follow-up after bracing is 13.9 ± 16.0 months (mean ± S.D., *P < .05). There was one recurrence, likely due to early discontinuation of maintenance. This responded to an additional 6 months of bracing. 42 patients failed therapy secondary to non-compliance or were lost in follow up, while 2 patients did not respond to bracing and required open operation. If patients are compliant, a self- adjusting brace system can give rapid correction of the pectus carinatum protrusion with excellent patient satisfaction. These interim results suggest that continued bracing until skeletal maturity gives long term durability to the correction. Further studies will be required to further refine this promising therapy.

To examine the influence of titration schedule and maintenance dose on the incidence and type of treatment-emergent adverse events (TEAEs) associated with adjunctive eslicarbazepine acetate (ESL). Data from three randomized, double-blind, placebo-controlled trials were analyzed. Patients with refractory partial-onset seizures were randomized to maintenance doses of ESL 400, 800, or 1200mg QD (dosing was initiated at 400 or 800mg QD) or placebo. The incidence of TEAEs was analyzed during the double-blind period (2-week titration phase; 12-week maintenance phase), according to the randomized maintenance dose and the titration schedule. 1447 patients were included in the analysis. During the first week of treatment, 62% of patients taking ESL 800mg QD had ≥1 TEAE, vs 35% of those taking 400mg QD and 32% of the placebo group; dizziness, somnolence, nausea, and headache were numerically more frequent in patients taking ESL 800mg than those taking ESL 400mg QD. During the double-blind period, the incidences of common TEAEs were lower in patients who initiated ESL at 400mg vs 800mg QD. For the 800 and 1200mg QD maintenance doses, rates of TEAEs leading to discontinuation were lower in patients who began treatment with 400mg than in those who began taking ESL 800mg QD. Initiation of ESL at 800mg QD is feasible. However, initiating treatment with ESL 400mg QD for 1 or 2 weeks is recommended, being associated with a lower incidence of TEAEs, and related discontinuations. For some patients, treatment may be initiated at 800mg QD, if the need for more immediate seizure reduction outweighs concerns about increased risk of adverse reactions during initiation.

To describe the dosing of etanercept and infliximab for the treatment of rheumatoid arthritis (RA). Adult patients with a diagnosis of RA who were treated with either etanercept or infliximab between 1999 and 2002 were selected from 16 rheumatology practices in the western and southeastern United States. Patients with a terminal illness or those receiving a tumor necrosis factor (TNF)-alpha inhibitor for an indication other than RA were excluded. Data were collected through a review of the patient medical records. Data collected on each patient included demographics, concurrent disease-modifying antirheumatic drug therapy, TNF-alpha inhibitor dose, frequency, duration of TNF-alpha inhibitor therapy, and discontinuation of TNF-alpha inhibitor therapy. A total of 244 patients were included in the evaluation (etanercept only [n=128; 52%], infliximab only [n=89; 36%], both [n=27; 11%]). The mean age of these patients was 55.1+/-13.3 years, 54.9+/-13.5 years, and 52.8+/-14.0 years, respectively; the mean duration of RA was 13.3 +/- 8.8 years, 13.4+/-8.0 years, and 14.0 +/- 9.9 years, respectively. Female patients constituted 70% of the sample. Health maintenance organization insurance was the most common form of medical insurance (45.8%), followed by Medicare (22.3%). The mean duration of follow-up for etanercept and infliximab treatment was 29.3+/-14.1 months and 14.8+/-6.9 months, respectively. Among patients who were still receiving therapy at the time of review, the mean initial and last etanercept doses were 25.0 mg versus 25.8 mg (P=0.16); the mean initial and last infliximab doses were 3.38 mg/kg versus 4.51 mg/kg (P<0.001). The dosing of etanercept and infliximab therapy was consistent with the approved labeling of both medications.

Update on the management of ulcerative colitis.

2012-01-01

The present treatment goals for inflammatory bowel diseases (IBD) especially ulcerative colitis (UC) include rapid induction of clinical remission, steroid-free maintenance of clinical remission, mucosal healing and improvement of quality of life in UC patients. Immunomodulators have been reserved for steroid- dependent or steroid- refractory UC patients. Among these agents, azathioprine/6-mercaptopurine should be used for maintenance of remission in quiescent UC. Calcineurin inhibitors can be prescribed as a short-term rescue therapy in steroid- refractory UC patients, but the long term efficacy of these agents remains unclear. According to retrospective studies, methotraxate is not recommended for inducing and maintaining remission in UC. Novel biological therapies targeting different specific immunological pathways continue to be developed and introduced for a variety of clinical scenarios in IBD. Infliximab is currently used for induction and maintenance therapy in patients who have moderately to severely active UC with an inadequate response to conventional agents such as aminosalicylates, corticosteroids, or immunomodulators. Other anti-TNF agents and biologic therapies are undergoing evaluation in clinical trials for their efficacy in IBD. Most patients who start biologics should continue treatment for the foreseeable future and potential consequences of discontinuation should be discussed with individual patients. Currently, data do not exist to administer biologics as first-line therapy in UC. Emerging data suggest that biologics may have the potential to prevent complications and limit disease progression. If such benefits are proven, biologics may be used in the future to modulate subclinical inflammation and to prevent the development of clinical disease.

Our purpose was to determine whether maintenance oral tocolytic therapy after preterm labor stabilization decreases uterine activity, reduces the rate of recurrent preterm labor and subsequent preterm birth, or improves neonatal outcome. Women with documented idiopathic preterm labor stabilized with acute tocolytic therapy were randomized to three groups: placebo, terbutaline 5 mg, or magnesium chloride 128 mg, all given orally every 4 hours. Patients and providers were blinded to group assignment. All subjects were enrolled in a comprehensive system of preterm birth prevention that included preterm labor education, weekly clinic visits, home uterine contraction assessment, daily phone contact, and 24-hour perinatal nurse access. Of the 248 patients who were randomized, 39 were delivered before discharge and 4 were lost to follow-up, leaving 205 for final analysis: 68 placebo, 72 terbutaline, and 65 magnesium. The terbutaline group had significantly more side effects than the placebo group did. All groups had otherwise similar perinatal outcomes when confounding variables were controlled for. Overall, the three groups had a preterm birth rate < 37 weeks of 55.6% delivery, < 34 weeks of 15.6%, a 20.4% rate of newborn intensive care unit admission, and a mean neonatal length of stay of 6.3 days. Maintenance oral tocolytic therapy did not decrease uterine activity, reduce the rate of recurrent preterm labor or preterm birth, or improve perinatal outcome. Overall improvement in perinatal outcome may be achieved with a comprehensive program of preterm birth prevention without the use of maintenance oral tocolytic therapy.

Cancer is a clonal malignant disease originated in a single cell and characterized by the accumulation of partially differentiated cells that are phenotypically reminiscent of normal stages of differentiation. According to current models, therapeutic strategies that block oncogene activity are likely to selectively target tumor cells. However, recent evidences have revealed that cancer stem cells could arise through a tumor stem cell reprogramming mechanism, suggesting that genetic lesions that initiate the cancer process might be dispensable for tumor progression and maintenance. This review addresses the impact of these results toward a better understanding of cancer development and proposes new approaches to treat cancer in the future. Copyright © 2014 Elsevier Ltd.

Music is capable of evoking exceptionally strong emotions and of reliably affecting the mood of individuals. Functional neuroimaging and lesion studies show that music-evoked emotions can modulate activity in virtually all limbic and paralimbic brain structures. These structures are crucially involved in the initiation, generation, detection, maintenance, regulation and termination of emotions that have survival value for the individual and the species. Therefore, at least some music-evoked emotions involve the very core of evolutionarily adaptive neuroaffective mechanisms. Because dysfunctions in these structures are related to emotional disorders, a better understanding of music-evoked emotions and their neural correlates can lead to a more systematic and effective use of music in therapy.

The management of patients who relapse after radical radiotherapy is a challenging problem for the multidisciplinary team. This group of men may have been considered ineligible or chosen not to be treated with an initial surgical approach as a result of high-risk features or significant comorbid conditions. It is important not to miss the opportunity for definitive local salvage therapies at this stage, and eligible patients should undergo careful restaging to determine their suitability for these approaches. For those men not suitable for local treatment, androgen deprivation therapy (ADT) remains an option. Literature review of the evidence relating to the management of hormone therapy for radiorecurrent prostate cancer. Results from retrospective studies have shown that not all men with biochemical relapse will experience distant metastasis or a reduction in survival due to prostate cancer progression. Therefore, the timing of ADT commencement remains controversial. However, it would seem appropriate to offer immediate therapy to men with advanced disease or unfavourable prostate-specific antigen (PSA) kinetics at relapse. Patients with more favourable risk factors and PSA kinetics may be considered for watchful waiting and deferred ADT to avoid or delay the associated toxicities. Patients with non-metastatic disease can be given the option of castration-based therapy or an antiandrogen such as bicalutamide which may have potential advantages in maintenance of sexual function, physical capacity and bone mineral density but at the expense of an increase in gynaecomastia and mastalgia. Recent data suggest the burden of toxicity from ADT may be reduced by the use of intermittent hormone therapy without compromising survival in this group of patients with radiorecurrence. Hormone therapy remains an option for men with radiorecurrent prostate cancer.

This 24-week, randomized, multicentre, open-label, parallel-group clinical trial compared efficacy and safety of repaglinide monotherapy, rosiglitazone monotherapy, and combination therapy (repaglinide plus rosiglitazone) in Type 2 diabetes after unsatisfactory response to sulphonylurea or metformin monotherapy. Enrolled patients (n = 252) were adults having Type 2 diabetes for at least 1 year, with HbA(1c) values > 7.0% after previous monotherapy (sulphonylurea or metformin, >/= 50% maximal dose). Prior therapy was withdrawn for 2 weeks, followed by randomization to repaglinide, rosiglitazone, or repaglinide/rosiglitazone. Study treatments were initiated with a 12-week dose optimization period (doses optimized according to labelling), followed by a 12-week maintenance period. Efficacy endpoints were changes in HbA(1c) values (primary) or fasting plasma glucose values (secondary). Baseline HbA(1c) values were comparable (9.3% for repaglinide, 9.0% for rosiglitazone, 9.1% for combination). Mean changes in HbA(1c) values at the end of treatment were greater for repaglinide/rosiglitazone therapy (-1.43%) than for repaglinide (-0.17%) or rosiglitazone (-0.56%) monotherapy. Reductions of fasting plasma glucose values were also greater for combination therapy (-5.2 mmol/l, -94 mg/dl) than for repaglinide monotherapy (-3.0 mmol/l, -54 mg/dl) or rosiglitazone monotherapy (-3.7 mmol/l, -67 mg/dl). Minor hypoglycaemic events occurred in 9% of combination therapy patients, vs. 6% for repaglinide and 2% for rosiglitazone. Individual weight gains for combination therapy were correlated to HbA(1c) response. The combination therapy regimen was well tolerated. In patients previously showing unsatisfactory response to oral monotherapy, glycaemic reductions were greater for the repaglinide/rosiglitazone combination regimen than for use of either repaglinide or rosiglitazone alone.

The success of antiretroviral therapy (ART) as treatment for the individual patient and as prevention requires the achievment and maintenance of human immunodeficiency virus (HIV) viral suppression. Linkage to and retention in care are required for access to ART. We describe the impact of care on viral suppression using routinely reported surveillance data. We included New York City residents ≥13 years of age, diagnosed with HIV/AIDS from 1 July 2005 to 30 June 2009 with a viral load (VL) or CD4 reported within six months of diagnosis and ≥1 VL reported from 1 July 2005 to 30 June 2011. To examine viral rebound, we restricted the analysis to those who achieved viral suppression and had a subsequent VL measure reported by 30 June 2011. Cox proportional hazards models were used to evaluate factors associated with time to viral suppression (VL ≤ 400 copies/mL) and rebound (VL > 1000 copies/mL). Initiation of care within three months of diagnosis (CD4/VL report within three months of diagnosis), female sex, and an initial CD4 < 350 (cells/mm(3)) at diagnosis significantly increased the likelihood of viral suppression. Irregular care (no CD4/VL reported every six months), younger age, non-white race/ethnicity, having an initial CD4 ≥ 350 at diagnosis, and AIDS diagnosis by 2010 increased the likelihood of rebound. These findings lend support to interventions for improving linkage to and maintenance in regular care as a way to achieve and maintain suppression. Surveillance data represent an ideal means for monitoring engagement in care and viral suppression at the population level.

Infliximab is an effective therapy for inflammatory bowel disease (IBD). However, more than 50% of patients lose response. Empiric dose intensification is not effective for all patients because not all patients have objective disease activity or subtherapeutic drug level. The aim was to determine how an objective marker of disease activity or therapeutic drug monitoring affects clinical decisions regarding maintenance infliximab therapy in outpatients with IBD. Consecutive patients with IBD on maintenance infliximab therapy were invited to participate by providing preinfusion stool and blood samples. Fecal calprotectin (FCP) and infliximab trough levels (ITLs) were measured by enzyme linked immunosorbent assay. Three decisions were compared: (1) actual clinical decision, (2) algorithmic FCP or ITL decisions, and (3) expert panel decision based on (a) clinical data, (b) clinical data plus FCP, and (c) clinical data plus FCP plus ITL. In secondary analysis, Receiver-operating curves were used to assess the ability of FCP and ITL in predicting clinical disease activity or remission. A total of 36 sets of blood and stool were available for analysis; median FCP 191.5 μg/g, median ITLs 7.3 μg/mL. The actual clinical decision differed from the hypothetical decision in 47.2% (FCP algorithm); 69.4% (ITL algorithm); 25.0% (expert panel clinical decision); 44.4% (expert panel clinical plus FCP); 58.3% (expert panel clinical plus FCP plus ITL) cases. FCP predicted clinical relapse (area under the curve [AUC] = 0.417; 95% confidence interval [CI], 0.197-0.641) and subtherapeutic ITL (AUC = 0.774; 95% CI, 0.536-1.000). ITL predicted clinical remission (AUC = 0.498; 95% CI, 0.254-0.742) and objective remission (AUC = 0.773; 95% CI, 0.622-0.924). Using FCP and ITLs in addition to clinical data results in an increased number of decisions to optimize management in outpatients with IBD on stable maintenance infliximab therapy.

Hepatic sinusoidal obstruction syndrome (SOS) during treatment of childhood acute lymphoblastic leukemia (ALL) has mainly been associated with 6-thioguanine. The occurrence of several SOS cases after the introduction of extended pegylated asparaginase (PEG-asparaginase) therapy in the Nordic Society of Paediatric Haematology and Oncology (NOPHO) ALL2008 protocol led us to hypothesize that PEG-asparaginase, combined with other drugs, may trigger SOS during 6-thioguanine-free maintenance therapy. In children with ALL treated in Denmark according to the NOPHO ALL2008 protocol, we investigated the risk of SOS during methotrexate (MTX)/6-mercaptopurine (6MP) maintenance therapy that included PEG-asparaginase until week 33 (randomized to two- vs. six-week intervals), as well as alternating high-dose MTX or vincristine/dexamethasone pulses every four weeks. Among 130 children receiving PEG-asparaginase biweekly, 29 developed SOS (≥2 criteria: hyperbilirubinemia, hepatomegaly, ascites, weight gain ≥2.5%, unexplained thrombocytopenia <75 × 10 9 l -1 ) at a median of 30 days (interquartile range [IQR]: 17-66) into maintenance (cumulative incidence: 27%). SOS cases fulfilling one, two, or three Ponte di Legno criteria were classified as possible (n = 2), probable (n = 8), or verified (n = 19) SOS, respectively. Twenty-six cases (90%) occurred during PEG-asparaginase treatment, including 21 (81%) within 14 days from the last chemotherapy pulse compared with the subsequent 14 days (P = 0.0025). Cytotoxic 6MP metabolites were significantly higher on PEG-asparaginase compared to after its discontinuation. Time-dependent Cox regression analysis showed increased SOS hazard ratio (HR) for erythrocyte levels of methylated 6MP metabolites (HR: 1.09 per 1,000 nmol/mmol hemoglobin increase, 95% confidence interval: 1.05-1.14). Six-week PEG-asparaginase intervals significantly reduced SOS-specific hazards (P < 0.01). PEG-asparaginase increases cytotoxic 6MP metabolite levels and risk of SOS, potentially interacting with other chemotherapy pulses. © 2017 Wiley Periodicals, Inc.

Concomitant use of ipratropium and tiotropium in chronic obstructive pulmonary disease.

To describe the current data evaluating the efficacy and safety of ipratropium used in combination with tiotropium in patients with chronic obstructive pulmonary disease. A literature search using MEDLINE (1966-August 2012) and EMBASE (1973-August 2012) was conducted using the search terms ipratropium, tiotropium, combination drug therapy, and chronic obstructive pulmonary disease. References of identified articles were reviewed for additional relevant citations. All English-language articles regarding the concomitant use of ipratropium and tiotropium were reviewed. Two prospective randomized controlled trials have demonstrated increases in bronchodilation with ipratropium when added to maintenance tiotropium therapy, suggesting potential benefits during short-term, combined use. One study reported significantly higher peak forced expiratory volume in 1 second (FEV(1)) responses with both ipratropium (230 mL) and fenoterol (315 mL) compared to placebo (178 mL) when added to maintenance tiotropium. The peak response with fenoterol was significantly higher than with ipratropium (FEV(1) difference = 84 mL). Another study reported a mean difference in FEV(1) of 81 mL (95% CI 27 to 136) with albuterol versus placebo and a mean difference in FEV(1) of 68 mL (95% CI 3 to 132) with ipratropium versus placebo. The difference between albuterol and ipratropium when added to maintenance tiotropium was not significant. One large observational study reported a significantly higher risk of acute urinary retention in individuals receiving combination therapy with a short- and long-acting anticholinergic agent compared to those receiving monotherapy (OR 1.84; 95% CI 1.25 to 2.71). Individuals at highest risk were men and those with evidence of benign prostatic hypertrophy. While ipratropium may provide spirometric improvements in lung function for patients receiving tiotropium maintenance therapy, the clinical significance of these improvements has not been documented and the risk of anticholinergic adverse effects is increased with combination therapy. Further studies evaluating the safety and efficacy of concomitant ipratropium and tiotropium are warranted before combination use can be recommended for select patients.

The cornerstone of emergency management of severe sepsis and septic shock is early (within 6 hours) goal-directed therapy, including maintenance of central venous pressure (CVP) at 8-12 mmHg. It is unclear whether there is a difference in initial (baseline) CVP between septic patients who are referred from the community and those who come from long-term care facilities (LTCFs) in Taiwan. We designed this study to investigate the difference in hemodynamic parameters between these two groups. Every patient with severe sepsis or septic shock who had a central venous catheter inserted via the internal jugular or subclavian vein at Kaohsiung Medical University Hospital between April 2007 and October 2007 was enrolled. CVP was measured immediately at the emergency department. Patient demographics, including residence, were retrospectively recorded and analyzed. There were 166 evaluable patients; 125 (75.3%) came from the community and 41 (24.7%) from LTCFs. There were no significant differences in age, sex, initial body temperature, heart rate, blood pressure, or leukocyte count between the two groups. However, patients who were referred from LTCFs had a significantly lower initial CVP than those from the community (5.0 ± 4.5 mmHg vs. 7.0 ± 4.8 mmHg, p = 0.023). The difference was more significant between mechanically ventilated patients from LTCFs and those from the community (5.0 ± 3.0 mmHg vs. 8.1 ± 5.6 mmHg, p = 0.006). Severely septic patients referred from LTCFs may require more aggressive fluid resuscitation within the first 6 hours of the diagnostic criteria met at the emergency department to achieve the CVP target of early goal-directed therapy.

Current and Potential Pharmacological Treatment Options for Maintenance Therapy in Opioid-Dependent Individuals

PubMed Central

Tetrault, Jeanette M.; Fiellin, David A.

2013-01-01

Opioid dependence, manifesting as addiction to heroin and pharmaceutical opioids is increasing. Internationally, there are an estimated 15.6 million illicit opioid users. The global economic burden of opioid dependence is profound both in terms of HIV and hepatitis C virus transmission, direct healthcare costs, and indirectly through criminal activity, absenteeism and lost productivity. Opioid agonist medications, such as methadone and buprenorphine, that stabilize neuronal systems and provide narcotic blockade are the most effective treatments. Prolonged provision of these medications, defined as maintenance treatment, typically produces improved outcomes when compared with short-duration tapers and withdrawal. The benefits of opioid agonist maintenance include decreased illicit drug use, improved retention in treatment, decreased HIV risk behaviours and decreased criminal behaviour. While regulations vary by country, these medications are becoming increasingly available internationally, especially in regions experiencing rapid transmission of HIV due to injection drug use. In this review, we describe the rationale for maintenance treatment of opioid dependence, discuss emerging uses of opioid antagonists such as naltrexone, and sustained-release formulations of naltrexone and buprenorphine, and provide a description of the experimental therapies.

Preservation of renal function during maintenance therapy with cyclosporine.

PubMed

Serón, D; Moreso, F

2004-03-01

During the last 20 years the management of cyclosporine (CsA) has improved due to the introduction of microemulsion technology, C2 monitoring, and combination with other new immunosuppressants. All these modifications have reduced the incidence of biopsy-proven acute rejection episodes to approximately 10%. However despite the wide experience, there are unanswered questions regarding CsA monitoring after the first year. Available clinical and histological data suggest that the therapeutic range to avoid nephrotoxicity or underimmunosuppression during the maintenance period is rather narrow. Furthermore, the combination of CsA with new immunosuppressants may modify the target CsA levels. Although the utility of C2 levels during the first year has been well characterized, there are few data on its utility for maintenance therapy, particularly the therapeutic range for C2 levels in patients receiving different immunosuppressive combinations. Since serum creatinine does not precisely reflect the progression of chronic allograft nephropathy, the efficacy of C2 monitoring during the maintenance period must be assessed not only by means of evaluation of renal function, but also histologic assessment using protocol biopsies.

AIM To elucidate the factors associated with residual gastroesophageal reflux disease (GERD) symptoms in patients receiving proton pump inhibitor (PPI) maintenance therapy in clinical practice. METHODS The study included 39 GERD patients receiving maintenance PPI therapy. Residual symptoms were assessed using the Frequency Scale for Symptoms of GERD (FSSG) questionnaire and the Gastrointestinal Symptom Rating Scale (GSRS). The relationships between the FSSG score and patient background factors, including the CYP2C19 genotype, were analyzed. RESULTS The FSSG scores ranged from 1 to 28 points (median score: 7.5 points), and 19 patients (48.7%) had a score of 8 points or more. The patients’ GSRS scores were significantly correlated with their FSSG scores (correlation coefficient = 0.47, P < 0.005). In erosive esophagitis patients, the FSSG scores of the CYP2C19 rapid metabolizers (RMs) were significantly higher than the scores of the poor metabolizers and intermediate metabolizers (total scores: 16.7 ± 8.6 vs 7.8 ± 5.4, P < 0.05; acid reflux-related symptom scores: 12 ± 1.9 vs 2.5 ± 0.8, P < 0.005). In contrast, the FSSG scores of the CYP2C19 RMs in the non-erosive reflux disease patients were significantly lower than those of the other patients (total scores: 5.5 ± 1.0 vs 11.8 ± 6.3, P < 0.05; dysmotility symptom-related scores: 1.0 ± 0.4 vs 6.0 ± 0.8, P < 0.01). CONCLUSION Approximately half of the GERD patients receiving maintenance PPI therapy had residual symptoms associated with a lower quality of life, and the CYP2C19 genotype appeared to be associated with these residual symptoms.

Studies on the use of low-dose proton pump inhibitor for the maintenance therapy of gastro-oesophageal reflux disease have shown that it might be comparable with standard-dose proton pump inhibitor treatment and superior to standard-dose histamine-2 receptor antagonist therapy. To compare the impact of standard-dose histamine-2 receptor antagonist, low-dose proton pump inhibitor and standard-dose proton pump inhibitor treatment for the maintenance therapy of gastro-oesophageal reflux disease on symptom control and health care resource utilization from the perspective of a public health organization in Hong Kong. A Markov model was designed to simulate, over 12 months, the economic and clinical outcomes of gastro-oesophageal reflux disease patients treated with standard-dose histamine-2 receptor antagonist, low-dose proton pump inhibitor and standard-dose proton pump inhibitor. The transition probabilities were derived from the literature. Resource utilization was retrieved from a group of gastro-oesophageal reflux disease patients in Hong Kong. Sensitivity analysis was conducted to examine the robustness of the model. The standard-dose proton pump inhibitor strategy was associated with the highest numbers of symptom-free patient-years (0.954 years) and quality-adjusted life-years gained (0.999 years), followed by low-dose proton pump inhibitor and standard-dose histamine-2 receptor antagonist. The direct medical cost per patient in the standard-dose proton pump inhibitor group (904 US dollars) was lower than those of the low-dose proton pump inhibitor and standard-dose histamine-2 receptor antagonist groups. The standard-dose proton pump inhibitor strategy appears to be the most effective and least costly for the maintenance management of patients with gastro-oesophageal reflux disease in Hong Kong.

To explore the necessity of maintenance, efficacy of low-dose and superiority of various combination therapies of Bacillus Calmette-Guérin (BCG) in treatment of superficial bladder cancer (BCa). Comprehensive searches of electronic databases (PubMed, Embase, and the Cochrane Library), were performed, then a systematic review and cumulative meta-analysis of 21 randomized, controlled trials (RCTs) and 9 retrospective comparative studies were carried out according to, predefined inclusion criteria. Significantly better recurrence-free survivals (RFS) were observed respectively in patients who received BCG maintenance, standard-dose and BCG plus epirubicin therapy comparing to those received induction, low-dose and BCG alone. BCG maintenance therapy was also associated with significantly better progression-free survival (PFS), but there were more incidences of adverse events. Pooled results showed no remarkable advantage of BCG combined with Mitomycin C or with interferon α-2b in improving oncologic outcomes. Sensitivity-analyses stratified by study-design and tumor stage led to very similar overall results and often to a decrease of the between-study heterogeneity. Our data confirmed that non-RCT only affected strength rather than direction of the overall results. All patients with superficial BCa should be encouraged to accept BCG maintenance therapy with standard-dose if well tolerated. Patients can benefit from BCG combined with epirubicin but not from BCG combined with Mitomycin C or interferon α-2b. Copyright © 2014 Elsevier Inc. All rights reserved.

Constipation is common in childhood. It can affect around 5-30% of the child population, depending on the criteria used for diagnosis. The currently recommended treatment is based on three main points: a) explanation, b) disimpaction and c) maintenance therapy consisting of diet changes, behavioural modification, and the use of laxatives. In the last decades treatment on disimpaction have changed radically from the rectal route to the oral route with polyethylene glycol 3350 (PEG), the most used and accepted regimen nowadays. Treatment and care should take into account the individual needs and preferences of the patient. Good communication is essential, to allow patients to reach informed decisions about their care. Maintenance therapy consists of dietary interventions, toilet training, and laxatives to obtain daily painless defaecation in order to prevent re-accumulation of stools. Maintenance therapy should be start as soon as the child's bowel is disimpacted. Early intervention with oral laxatives may improve complete resolution of functional constipation. Enemas using phosphate, mineral oil, or normal saline are effective in relieving rectal impaction, but carry the risk of mechanical trauma and are not recommended for maintenance therapy in the paediatric population. Among osmotic agents, polyethylene glycol 3350 plus electrolyte solutions appear to be the first-line drug treatment to use in children of any age, as it is safe, effective, and well-tolerated. Recommended doses ranges from 0.25 to 1.5g/kg. Advances in the understanding of the gastrointestinal enteric nervous system and epithelial function have led to the development of new substances that bind to serotonin receptors or are chloride channel activators.

To evaluate the results of a 3-year follow-up of intravitreal pegaptanib sodium injection as maintenance therapy for the treatment of neovascular age-related macular degeneration (AMD) in Japanese patients. In this prospective, uncontrolled interventional study, 20 eyes of 19 patients with treatment-naïve AMD who had received 3 consecutive monthly injections of 0.5 mg/0.05 mL ranibizumab as the induction treatment and had shown clinical/anatomical improvement were enrolled. An intravitreal injection of 0.3 mg/0.09 mL pegaptanib sodium was administered as the maintenance therapy every 6 weeks. Booster treatments using ranibizumab were allowed if clinical deterioration was judged to be present. The primary outcome measures were the best-corrected visual acuity (BCVA) and the central foveal thickness (CFT) as evaluated using spectral-domain optical coherence tomography. Sixteen of the 20 eyes (80 %) were assessed at the 3-year follow-up. The mean logMAR BCVA improved significantly from 0.56 ± 0.31 before the induction treatment to 0.24 ± 0.25 at baseline (P < 0.001) and was well maintained at 156 weeks (0.25 ± 0.28, P = 0.938). Moreover, the mean CFT also decreased significantly from 346 ± 111 μm before the induction treatment to 232 ± 54 μm at baseline (P < 0.001) and was well preserved at 156 weeks (210 ± 59 μm, P = 0.278). Thirteen eyes (81.3 %) received an unscheduled booster treatment, and no severe systemic or ocular side effects occurred during follow-up. Intravitreal pegaptanib sodium injection as the maintenance therapy was effective in stabilizing the vision of patients with AMD in whom induction treatment led to improved BCVA, as evaluated at the 3-year follow-up.

Abstract Objective A weight loss maintenance trial involving weight loss prior to randomization is challenging to implement due to the potential for dropout and insufficient weight loss. We examined rates and correlates of non‐initiation, dropout, and insufficient weight loss during a weight loss maintenance trial. Methods The MAINTAIN trial involved a 16‐week weight loss program followed by randomization among participants losing at least 4 kg. Psychosocial measures were administered during a screening visit. Weight was obtained at the first group session and 16 weeks later to determine eligibility for randomization. Results Of 573 patients who screened as eligible, 69 failed to initiate the weight loss program. In adjusted analyses, failure to initiate was associated with lower age, lack of a support person, and less encouragement for making dietary changes. Among participants who initiated, 200 dropped out, 82 lost insufficient weight, and 222 lost sufficient weight for randomization. Compared to losing sufficient weight, dropping out was associated with younger age and tobacco use, whereas losing insufficient weight was associated with non‐White race and controlled motivation for physical activity. Conclusions Studies should be conducted to evaluate strategies to maximize recruitment and retention of subgroups that are less likely to initiate and be retained in weight loss maintenance trials.

Pandit, Sandeep V.; Jalife, José

2013-01-01

The objective of this article is to present a broad review on the role of cardiac electrical rotors and their accompanying spiral waves in the mechanism of cardiac fibrillation. At the outset, we present a brief historical overview regarding reentry, and then discuss the basic concepts and terminologies pertaining to rotors and their initiation. Thereafter, the intrinsic properties of rotors and spiral waves, including phase singularities, wavefront curvature and dominant frequency maps are discussed. The implications of rotor dynamics for the spatio-temporal organization of fibrillation, independent of the species being studied are touched upon next. The knowledge gained regarding the role of cardiac structure in the initiation and/or maintenance of rotors and the ionic bases of spiral waves in the last two decades, and its significance for drug therapy is reviewed subsequently. We conclude by looking at recent evidence suggesting that rotors are critical in sustaining both atrial and ventricular fibrillation (AF, VF) in the human heart, and its implications for treatment with radio-frequency ablation.

Pham, Cindy

2017-01-01

Adult-onset Still’s disease (AOSD) is a systemic autoinflammatory disease characterized by symptoms including spiking fever, arthralgia, myalgia, maculopapular rash, and pharyngitis. The lack of diagnostic biomarker, non-specific clinical presentation, and the rarity of AOSD often result in a significant delay in diagnosis and treatment. While the average time of initial presentation to diagnosis is four months, we present a case of AOSD diagnosis three years after initial onset of classical symptoms. By reporting the case of delayed diagnosis for AOSD, we hope to raise awareness in our medical community about the diagnostic difficulty in AOSD. The present case describes an otherwise healthy male who presented with typical symptoms of AOSD, but the diagnosis of AOSD was missed during his first presentation. In the second flaring episode, the diagnosis of AOSD was established. He had an excellent therapeutic response to anakinra and prednisone during the acute flaring episode. He is currently in complete remission on methotrexate as maintenance therapy. PMID:28690954

Mammalian target of rapamycin (mTOR) inhibitors, everolimus (EVL) and sirolimus are immunosuppressive agents with a minor nephrotoxic effect, limited to the development of proteinuria in some cases. The combination of EVL and low-dose tacrolimus has proven to be as safe and effective as standard therapy with tacrolimus for the prevention of acute cellular rejection. Early initiation of EVL-based immunosuppressive regimens with reduced exposure to calcineurin inhibitors has been shown to significantly improve renal function of LT recipients during induction and maintenance phases, with comparable efficacy and safety profiles. In patients with established kidney failure, initiating EVL may enable clinicians to reduce calcineurin inhibitors exposure, thereby contributing to the improved renal function of these patients. Although there is not sufficient evidence to recommend their use to prevent the recurrence of hepatocellular carcinoma and the progression of de novo tumours, they are used in this context in routine clinical practice.

Simple Model for Identifying Critical Regions in Atrial Fibrillation

Christensen, Kim; Manani, Kishan A.; Peters, Nicholas S.

2015-01-01

Atrial fibrillation (AF) is the most common abnormal heart rhythm and the single biggest cause of stroke. Ablation, destroying regions of the atria, is applied largely empirically and can be curative but with a disappointing clinical success rate. We design a simple model of activation wave front propagation on an anisotropic structure mimicking the branching network of heart muscle cells. This integration of phenomenological dynamics and pertinent structure shows how AF emerges spontaneously when the transverse cell-to-cell coupling decreases, as occurs with age, beyond a threshold value. We identify critical regions responsible for the initiation and maintenance of AF, the ablation of which terminates AF. The simplicity of the model allows us to calculate analytically the risk of arrhythmia and express the threshold value of transversal cell-to-cell coupling as a function of the model parameters. This threshold value decreases with increasing refractory period by reducing the number of critical regions which can initiate and sustain microreentrant circuits. These biologically testable predictions might inform ablation therapies and arrhythmic risk assessment.

Atopic dermatitis is a chronic skin disorder with high prevalence, especially in the Nordic countries. Effective maintenance therapy during symptom-free episodes may prolong the time to eczema relapse according to a previously published clinical trial. The present study evaluates the cost-effectiveness of a barrier-strengthening moisturizer containing 5% urea, compared with a moisturizer with no active ingredients during eczema-free periods. A health economic microsimulation model, based on efficacy data from the randomized clinical trial, analysed the cost-effectiveness of the barrier-strengthening treatment in Finland, Norway and Sweden. The barrier-strengthening moisturizer was cost-saving compared with the moisturizer with no active ingredients in all 3 countries. The result was confirmed in all but one sensitivity analysis. In conclusion, the barrier-strengthening moisturizer is cost-effective as maintenance therapy for patients with atopic dermatitis compared with a moisturizer with no active ingredients.

Wund-D.A.CH. is the umbrella organization of the various wound care societies in German-speaking countries. The present consensus paper on practical aspects pertinent to compression therapy in patients with venous leg ulcers was developed by experts from Germany, Austria, and Switzerland. In Europe, venous leg ulcers rank among the most common causes of chronic wounds. Apart from conservative and interventional wound and vein treatment, compression therapy represents the basis of all other therapeutic strategies. To that end, there are currently a wide variety of materials and systems available. While especially short-stretch bandages or multicomponent systems should be used in the initial decongestion phase, ulcer stocking systems are recommended for the subsequent maintenance phase. Another - to date, far less common - alternative are adaptive Velcro bandage systems. Medical compression stockings have proven particularly beneficial in the prevention of ulcer recurrence. The large number of treatment options currently available enables therapists to develop therapeutic concepts geared towards their patients' individual needs and abilities, thus resulting in good acceptance and adherence. Compression therapy plays a crucial role in the treatment of patients with venous leg ulcers. In recent years, a number of different treatment options have become available, their use and application differing among German-speaking countries. The present expert consensus is therefore meant to outline concrete recommendations for routine implementation of compression therapy in patients with venous leg ulcers. © 2016 Deutsche Dermatologische Gesellschaft (DDG).

This multicenter study evaluated the feasibility of novel adjuvant chemotherapy with S-1 plus carboplatin followed by single-agent, long-term maintenance with S-1 in patients with completely resected stage II-IIIA non-small-cell lung cancer (NSCLC). Patients received four cycles of S-1 (80 mg/m 2 /day for 2 weeks, followed by 2 weeks rest) plus carboplatin (area under the curve 5, day 1) followed by S-1 (80 mg/m 2 /day for 2 weeks, followed by a 1-week rest). Patients unable to continue S-1 plus carboplatin because of severe toxicity converted to single-agent S-1 maintenance. The duration of adjuvant chemotherapy was 10 months in both situations. The primary endpoint was feasibility, defined as the proportion of patients who completed four cycles of S-1 plus carboplatin and single-agent S-1 maintenance for 10 months. The treatment completion rate was determined; treatment was considered feasible if the lower 90% confidence interval (CI) was ≥50%. Eighty-nine patients were enrolled, of whom 87 were eligible and assessable. Seventy-eight patients (89.7%) completed four cycles of S-1 plus carboplatin and 55 (63.2%) completed the following S-1 maintenance therapy for a total of 10 months. The treatment completion rate was 63.2% (90% CI, 54.4-71.2%), indicating feasibility. There were no treatment-related deaths. Grade 3/4 toxicities included neutropenia (13.8%), thrombocytopenia (11.5%), and anorexia (4.6%). The 2-year relapse-free survival rate was 59.8%. We concluded that adjuvant chemotherapy with S-1 plus carboplatin followed by single-agent maintenance therapy with S-1 is feasible and tolerable in patients with completely resected NSCLC.

A correct therapeutic management of acne should include a maintenance therapy to prevent recurrences after discontinuing a successful treatment. The aim of this study is to investigate efficacy and safety of a 12-month maintenance treatment with a product, based on Retinsphere technology that combines retinol encapsulated in glycospheres and hydroxypinacolone retinoate (Biretix gel®), to control acne relapse after a treatment with oral isotretinoin (O.I.). The study consisted of 2 phases: active treatment phase (AP) and maintenance phase (MP). In the AP, 40 consecutive patients with moderate facial acne were treated with O.I. until acne remission. Then, the patients entered in the MP and were treated with Biretix gel® once-daily for 12 months. The efficacy parameter was the relapse rate during MP. Thirty-nine patients completed the study. Relapse appeared in 6 patients (15.38%). The new product with Retinsphere technology was well tolerated and none of the subjects complained of adverse events. Our findings seems to provide favorable evidence of the efficacy and the safety of this new product in the maintenance treatment after O.I. in patient with moderate acne. The efficacy is maintain for a period as long as a year after O.I. suspension.

Maintenance electroconvulsive therapy (M-ECT) after acute response: examining the evidence for who, what, when, and how?

Rabheru, Kiran

2012-03-01

To examine the evidence for maintenance electroconvulsive therapy (M-ECT) to help determine who, when, and how long ECT should be continued. A review of published literature on the use of maintenance ECT (M-ECT) was conducted. It focused primarily on trials published since 1997, meeting the following additional criteria: randomized controlled trial or cohort study with a comparison (matched group or before and after), and at least 10 patients receiving M-/continuation ECT. Where such data are not available, recent case series were reviewed. Relapse rates after discontinuation of ECT are very high. Maintenance ECT is an underused treatment option that can substantially reduce risks of relapse in patients with major depressive disorder and likely in bipolar disorder and schizophrenia as well. Little data are available for the use of M-ECT in neurological disorders, and no cost-effectiveness analyses in the maintenance setting were found. Whereas no clear answers emerge from the literature, there is now a growing body of evidence to suggest that for those who have not responded well to medications but have responded to ECT, M-ECT must be presented as an option to the patient and the family for consideration. Clear consensus guidelines for the use of M-ECT are needed.

SUMMARY Lin28a/b are RNA-binding proteins that influence stem cell maintenance, metabolism, and oncogenesis. Poorly differentiated, aggressive cancers often overexpress Lin28, but its role in tumor initiation or maintenance has not been definitively addressed. We report that LIN28B overexpression is sufficient to initiate hepatoblastoma and hepatocellular carcinoma in murine models. We also detected Lin28b overexpression in MYC-driven hepatoblastomas, and liver-specific deletion of Lin28a/b reduced tumor burden, extended latency, and prolonged survival. Both intravenous siRNA against Lin28b and conditional Lin28b deletion reduced tumor burden and prolonged survival. Igf2bp proteins are upregulated and Igf2bp3 is required in the context of LIN28B overexpression to promote growth. Thus, multiple murine models demonstrate that Lin28b is both sufficient to initiate liver cancer and necessary for its maintenance. PMID:25117712

Purpose Isometric progressive resistance oropharyngeal (I-PRO) therapy improves swallowing function; however, current devices utilize a single sensor that provides limited information or are prohibitively expensive. This single-subject study presents results of I-PRO therapy, detraining, and maintenance using the 5-sensor Madison Oral Strengthening Therapeutic (MOST) device combined with upper esophageal sphincter (UES) dilatation. Methods A 56-year-old female nurse who was 27 months post stroke and subsequent to traditional behavioral interventions and UES dilatations presented limited to gastrostomy tube intake only and expectorating all saliva. She completed 8 weeks of I-PRO therapy, 5 weeks of detraining, and 9 weeks of I-PRO maintenance (reduced frequency) followed by a third UES dilatation post intervention. Data included diet inventory, lingual pressures (MOST), lingual volume (magnetic resonance imaging), postswallow residue (videofl uoroscopy), UES and pharyngeal pressures (high-resolution manometry), and quality of life (QOL). Results Findings after 8 weeks of I-PRO therapy were progression to general oral diet, 15 lb weight gain, increased isometric pressures (Δ >16 kPa) with transference to swallowing pressures, increased lingual volume (8.3%), reduced pharyngeal wall residue (P = .03), increased pharyngeal pressures (Δ > 43 mm Hg) and increased UES opening (nadir) pressures (Δ > 9 mm Hg) with improved temporopressure coordination across the pharynx, and improved QOL. After detraining, decreased isometric pressures and reduced UES opening were noted. After I-PRO maintenance, isometric anterior lingual pressures returned to levels noted after the 8 weeks of intervention. Conclusion I-PRO therapy, facilitated by the MOST device combined with instrumental UES dilatation, improved swallow safety, increased oropharyngeal intake, and facilitated UES opening while enriching QOL.

We conducted a prospective Phase II study of high-dose methotrexate (HD-MTX) and rituximab with deferred whole brain radiotherapy in patients with newly diagnosed B-cell primary central nervous system lymphoma with a primary objective of evaluating progression-free survival (PFS). Forty patients (25 men; 15 women), ages 18-93 years (median 61.5), were treated. All patients received biweekly HD-MTX/rituximab (8 g/m(2)/dose; 375 mg/m(2)/dose) for 4-6 cycles (induction) and following best radiographic response, with every 4 weeks HD-MTX (8 g/m(2)/dose) for 4 cycles (maintenance). Neurological and neuroradiographic evaluation were performed every 4 weeks during induction therapy and every 8 weeks during maintenance therapy. All patients were evaluable. A total of 303 cycles of HD-MTX (median 8 cycles; range 4-10) was administered. HD-MTX/rituximab-related toxicity included 16 grade 3 adverse events in 13 patients (32.5%). Following induction, 8 patients (20%) demonstrated progressive disease and discontinued therapy; 32 patients (80%) demonstrated a partial (8/40; 20%) or complete (24/40; 60%) radiographic response. At the conclusion of maintenance therapy (6-10 months of total therapy), 28 patients (70%) demonstrated either a partial (1/28) or complete (27/28) response. Overall, survival of these 28 patients ranged from 11 to 80 months (median 33.5). Survival in the entire cohort ranged from 6 to 80 months with an estimated median of 29 months. Overall, PFS ranged from 2 to 80 months (median 21.0). HD-MTX/rituximab and deferred radiotherapy demonstrated similar or better efficacy similar to other HD-MTX-only regimens and reduced time on therapy on average to 6 months.

Mantle-cell lymphoma is generally incurable. Despite high rates of complete response after initial immunochemotherapy followed by autologous stem-cell transplantation, patients have relapses. We investigated whether rituximab maintenance therapy at a dose of 375 mg per square meter of body-surface area administered every 2 months for 3 years after transplantation would prolong the duration of response. In a phase 3 trial involving 299 patients who were younger than 66 years of age at diagnosis, we randomly assigned 240 patients to receive rituximab maintenance therapy or to undergo observation after autologous stem-cell transplantation (120 patients per group); 59 patients did not undergo randomization. The primary end point was event-free survival (with an event defined as disease progression, relapse, death, allergy to rituximab, or severe infection) after transplantation among patients who underwent randomization. After four courses of immunochemotherapy induction (rituximab, dexamethasone, cytarabine, and a platinum derivative [R-DHAP]), the overall response rate was 89%, and the complete response rate 77%. Transplantation was performed in 257 patients. The median follow-up from randomization after transplantation was 50.2 months (range, 46.4 to 54.2). Starting from randomization, the rate of event-free survival at 4 years was 79% (95% confidence interval [CI], 70 to 86) in the rituximab group versus 61% (95% CI, 51 to 70) in the observation group (P=0.001). The rate of progression-free survival at 4 years was 83% (95% CI, 73 to 88) in the rituximab group versus 64% (95% CI, 55 to 73) in the observation group (P<0.001). The rate of overall survival was 89% (95% CI, 81 to 94) in the rituximab group versus 80% (95% CI, 72 to 88) in the observation group (P=0.04). According to a Cox regression unadjusted analysis, the rate of overall survival at 4 years was higher in the rituximab group than in the observation group (hazard ratio for death, 0.50; 95% CI, 0.26 to 0.99; P=0.04). Rituximab maintenance therapy after transplantation prolonged event-free survival, progression-free survival, and overall survival among patients with mantle-cell lymphoma who were younger than 66 years of age at diagnosis.

2017-12-01

Opioid agonist therapy (OAT) is the standard of care for pregnant women with opioid use disorder (OUD). Medicaid coverage policies may strongly influence OAT use in this group. To examine the association between Medicaid coverage of methadone maintenance and planned use of OAT in the publicly funded treatment system. Retrospective cross-sectional analysis of treatment admissions in 30 states extracted from the Treatment Episode Data Set (2013 and 2014). Medicaid-insured pregnant women with OUD (n=3354 treatment admissions). The main outcome measure was planned use of OAT on admission. The main exposure was state Medicaid coverage of methadone maintenance. Using multivariable logistic regression models adjusting for sociodemographic, substance use, and treatment characteristics, we compared the probability of planned OAT use in states with Medicaid coverage of methadone maintenance versus states without coverage. A total of 71% of pregnant women admitted to OUD treatment were 18-29 years old, 85% were white non-Hispanic, and 56% used heroin. Overall, 74% of admissions occurred in the 18 states with Medicaid coverage of methadone maintenance and 53% of admissions involved planned use of OAT. Compared with states without Medicaid coverage of methadone maintenance, admissions in states with coverage were significantly more likely to involve planned OAT use (adjusted difference: 32.9 percentage points, 95% confidence interval, 19.2-46.7). Including methadone maintenance in the Medicaid benefit is essential to increasing OAT among pregnant women with OUD and should be considered a key policy strategy to enhance outcomes for mothers and newborns.

Oral antiplatelet agents for the management of acute coronary syndromes: A review for nurses and allied healthcare professionals.

Gesheff, Tania; Barbour, Cescelle

2017-02-01

We review the use of oral antiplatelet (OAP) therapies in acute coronary syndrome (ACS) management for nurse practitioners (NPs), focusing on current guideline recommendations. Treatment guidelines and clinical articles from PubMed. Guidelines recommend that dual antiplatelet therapy with a P2Y 12 inhibitor and aspirin be initiated for ACS management. The P2Y 12 inhibitor clopidogrel has established efficacy, but is associated with suboptimal and delayed platelet inhibition and variability in response. The newer P2Y 12 inhibitors prasugrel and ticagrelor have demonstrated superior efficacy outcomes versus clopidogrel. Consequently, non-ST-segment elevation ACS (NSTE-ACS) guidelines now recommend that ticagrelor be used in preference to clopidogrel for patients treated with stents or managed medically. Because of their higher potency, prasugrel and ticagrelor are associated with increased bleeding rates versus clopidogrel, but with no increased risk of severe or life-threatening bleeding. Guidelines recommend dual antiplatelet therapy be continued ≥12 months in both medically managed and stented ACS patients, and in some cases beyond this, in absence of high bleeding risk. Updated guidelines assign preference to ticagrelor over clopidogrel for maintenance therapy in patients with NSTE-ACS and ST-elevation myocardial infarction. Enhanced NP understanding of OAP agents and current guidelines could contribute to improved ACS patient management. ©2017 American Association of Nurse Practitioners.

New developments in psychosocial interventions for adults with unipolar depression.

PubMed

Lau, Mark A

2008-01-01

Depression treatment guidelines typically recommend cognitive behavioral therapy and/or interpersonal therapy for the acute treatment of mild-moderate depression. However, several new developments support an expanded role for psychotherapy in depression treatment. This article summarizes recent psychotherapy efficacy studies across the depression treatment continuum and the effectiveness of psychosocial interventions in community settings. New psychotherapies in the acute treatment of mild-moderate depression include emotion-focused therapy, self-system therapy, cognitive control training and positive psychotherapy. Furthermore, emerging evidence supports the use of psychotherapy for moderate-severe and treatment-resistant depression and for recurrent depression with a seasonal pattern. An important area of growth is the development and evaluation of continuation/maintenance treatments based on cognitive behavioral therapy and interpersonal therapy to reduce depressive relapse risk in recurrent and chronic depression. Finally, there is evidence supporting the effectiveness of stepped care, chronic disease management and collaborative care models in community settings. Emerging evidence supports an expanded role for the use of psychosocial interventions as acute and continuation/maintenance treatments for unipolar depression. Although further research is required to replicate these findings, a remaining challenge is to increase the availability of these treatments to the mental health consumer.

Combination Platinum-based and DNA Damage Response-targeting Cancer Therapy: Evolution and Future Directions

PubMed Central

Basourakos, Spyridon P.; Li, Likun; Aparicio, Ana M.; Corn, Paul G.; Kim, Jeri; Thompson, Timothy C.

2017-01-01

Maintenance of genomic stability is a critical determinant of cell survival and is necessary for growth and progression of malignant cells. Interstrand crosslinking (ICL) agents, including platinum-based agents, are first-line chemotherapy treatment for many solid human cancers. In malignant cells, ICL triggers the DNA damage response (DDR). When the damage burden is high and lesions cannot be repaired, malignant cells are unable to divide and ultimately undergo cell death either through mitotic catastrophe or apoptosis.

Maintenance of genomic stability is a critical determinant of cell survival and is necessary for growth and progression of malignant cells. Interstrand crosslinking (ICL) agents, including platinum-based agents, are first-line chemotherapy treatment for many solid human cancers. In malignant cells, ICL triggers the DNA damage response (DDR). When the damage burden is high and lesions cannot be repaired, malignant cells are unable to divide and ultimately undergo cell death either through mitotic catastrophe or apoptosis. The activities of ICL agents, in particular platinum-based therapies, establish a "molecular landscape," i.e., a pattern of DNA damage that can potentially be further exploited therapeutically with DDR-targeting agents. If the molecular landscape created by platinum-based agents could be better defined at the molecular level, a systematic, mechanistic rationale(s) could be developed for the use of DDR-targeting therapies in combination/maintenance protocols for specific, clinically advanced malignancies. New therapeutic drugs such as poly(ADP-ribose) polymerase (PARP) inhibitors are examples of DDR-targeting therapies that could potentially increase the DNA damage and replication stress imposed by platinum-based agents in tumor cells and provide therapeutic benefit for patients with advanced malignancies.

Pregnant women in methadone maintenance therapy may have poor nutrition during pregnancy. In 2006-2008, methadone-treated pregnant women (n = 22) were recruited at an urban academic medical center and compared with nondrug-using pregnant women (n = 119) at 20-35 weeks' gestation. We measured adiposity using prepregnancy body mass index (BMI), dietary intake using a food frequency questionnaire, and micronutrient and essential fatty acid status using biomarkers. Methadone-treated women had lower BMI, consumed more calories, had lower serum carotenoid concentrations, and higher plasma homocysteine concentrations than controls. The study's limitations and implications for future research are discussed.

A TAD better for myeloma therapy?

In this issue of Blood, Lokhorst and colleagues report on the results of HOVON-50, a phase 3 randomized trial designed to evaluate the effects of thalidomide during induction treatment and as maintenance in patients with multiple myeloma. There were 556 patients randomly assigned either to 3 cycles of VAD or to TAD. All patients were to receive high-dose melphalan with autologous stem cell support followed by maintenance with interferon for the VAD arm or thalidomide for the TAD arm.(1) This study together with other randomized and nonrandomized trials establish a definitive role for thalidomide as induction therapy in conjunction with dexamethasone, anthracyclines, and alkylating agents.

Buprenorphine does not aggravate ischemic neuronal injury in experimental focal cerebral ischemia.

2007-01-01

Buprenorphine has been increasingly used as maintenance therapy in opioid dependence as an alternative to methadone and other pharmacological therapies. However, available data suggest increased risk of cerebrovascular events in opioid-dependent patients. Therefore, an opioid that provides safety with regard to neurological function should be considered by opioid-dependent patients. The evidence for the in vitro neurotoxic effects of buprenorphine is rapidly increasing. In order to clarify whether buprenorphine is also neurotoxic under the condition of cerebral ischemia in vivo, we applied an acute dose of buprenorphine in a transient model of focal cerebral ischemia in rats. Our study provides preclinical evidence for the usage of buprenorphine during the postoperative period following ischemic events as well as for the maintenance therapy of opioid-dependent patients wherein the risk of cerebrovascular events is increased.

2018-05-01

Approximately 50% of high-grade serous ovarian cancers present a deficiency in the pathways involved in homologous recombination (HR). PARP inhibitors prevent single-strand DNA damage repair and determine a progression of the defect towards double-strand breaks, which results in a process known as 'synthetic lethality'. Areas covered: In this review, the authors discuss the efficacy and toxicity of rucaparib either as a single agent or as a maintenance treatment for ovarian cancer. This includes the NGS Foundation Medicine evaluation of the role of this drug in the treatment algorithm of ovarian cancer. Moreover, perspectives on the future development of this drug are presented. Expert opinion: The FDA has approved this drug for the treatment of recurrent BRCA-mutated ovarian cancers, which were previously treated with at least two chemotherapies and has accepted the supplemental new drug application for maintenance use in patients who respond to platinum-based chemotherapy via the Prescription Drug User Fee Act (PDUFA) on 6 April 2018. European Medicines Agency (EMA) approval in the same setting is awaited. The possibility of using PARP inhibitors as a maintenance therapy, as a front-line therapy to combat recurrence, and in combination with anti-angiogenic agents and immune-therapies appears to be of particular interest.

Reinduction therapy for adult acute leukemia with adriamycin, vincristine, and prednisone: a Southwest Oncology Group study.

PubMed

Elias, L; Shaw, M T; Raab, S O

1979-08-01

In an attempt to improve remissions and survivals in previously treated patients with adult acute leukemia, we gave Adriamycin, vincristine, and prednisone for induction therapy, followed by 6-mercaptopurine and methotrexate for maintenance therapy to patients attaining complete remission (CR). The study group consisted of 18 patients with acute myeloblastic leukemia (AML), ten with acute lymphoblastic leukemia, and one with acute undifferentiated leukemia. Only one patient had previously received Adriamycin. Overall, there were ten CRs and two partial remissions. The five CRs and one partial remission in patients with AML occurred among those with one prior induction attempt; none of the eight AML patients with more than one prior induction attempt responded. The actuarial median duration of CR was 15 weeks and was similar for AML and acute lymphoblastic leukemia patients. Responders had a longer median survival (30 weeks) than nonresponders (9 weeks). Thus, although a reasonable number of responses in previously treated patients were obtained with this program, improvements in maintenance therapy are clearly needed.

To demonstrate a favorable effect of propofol on respiratory system resistance during anesthetic induction, and to determine if generic propofol causes adverse effects on respiratory resistance. Randomized pilot study. Anesthetic induction for elective surgery. 27 consenting ASA physical status II and III patients with reactive airways (positive smoking history or chronic obstructive pulmonary disease), but not receiving bronchodilator therapy. Patients were randomized equally to one of three anesthetic induction (and maintenance) drugs: sodium thiopental, 5 mg/kg (25 microg/kg/min), generic or nongeneric propofol, 1.25 mg/kg (50 microg/kg/min). They received preinduction midazolam and fentanyl (2 mg and 150 microg) and intravenous lidocaine (0.5 mg/kg). After anesthetic induction, tracheal intubation was established, and predetermined settings for mechanical ventilation were initiated. Immediately after intubation, a sensor was placed on the 8-mm endotracheal tube to detect baseline airway pressure and flow. During maintenance, repeat measurements of pressure and flow were obtained at 2.5-minute intervals for 10 minutes. Respiratory system resistance was derived off-line using the isovolumetric technique. Patients were similar across groups. The respiratory resistance measured after anesthetic induction did not differ among groups. During the maintenance infusion of thiopental or propofol, respiratory resistance increased gradually across all groups. There was no difference in the response of respiratory resistance either at induction or during the 10-minute maintenance between the generic and the nongeneric propofol groups. In contrast to earlier reports, this pilot study was unable to document a difference in the respiratory resistance in patients induced with thiopental or propofol. In addition, we were unable to demonstrate any different respiratory responses between generic propofol, containing sodium metabisulfite preservative, and nongeneric propofol.

Existing evidence concerning the validity of an appropriate regular periodontal maintenance (PM) regimen and the role of patient compliance is controversial and inconsistent. The objectives of this study are to identify the impact of patient compliance (complete versus erratic) on alveolar bone loss and tooth survival. A retrospective study was conducted using data from 295 patients with >or=20 years of observation, which included treatment and >or=15 years of maintenance therapy, in a private practice in Yamagata, Japan. Subject-level variables and tooth-level variables were recorded at the initial visit, the reevaluation visit, and the final visit. In total, 7,502 teeth in 295 subjects met inclusion criteria and were divided into two groups: non-molar teeth (n = 5,585) and molar teeth (n = 1,917). A tooth-level multivariate survival model and multiple logistic regression model using the method of generalized estimating equations were constructed to analyze the effects of compliance and periodontal maintenance intervals on tooth loss and alveolar bone loss, respectively. Of 7,502 teeth, 284 molar teeth and 364 non-molar teeth were lost. Molar teeth had an approximately 30% reduction in risk of tooth loss for complete compliance, with 2-year compliance classification achieving statistical significance (P = 0.033), and 30% compliance classification approaching statistical significance (P = 0.072). Complete compliers under 30% compliance classification showed over 50% reduction in the risk of alveolar bone loss among non-molars (P = 0.015). Complete patient compliance with increased frequency of periodontal maintenance is important for improved dental prognosis through reduction of tooth loss among molars and minimization of alveolar bone loss among non-molars.

Acute myeloid leukaemia (AML) with FLT3 mutation has a dismal prognosis in elderly patients. Treatment with a combination of FLT3 inhibitors and standard chemotherapy has not been extensively studied. Therefore, we instigated a phase I/II clinical trial of chemotherapy with cytosine arabinoside (Ara-C)/daunorubicin induction (7+3) followed by three cycles of intermediate-dose Ara-C consolidation in 22 AML patients with activating FLT3 mutations. Sunitinib was added at predefined dose levels and as maintenance therapy for 2 years. At dose level 1, sunitinib 25 mg daily continuously from day 1 onwards resulted in two cases with dose-limiting toxicity (DLT), prolonged haemotoxicity and hand-foot syndrome. At dose level -1, sunitinib 25 mg was restricted to days 1-7 of each chemotherapy cycle. One DLT was observed in six evaluable patients. Six additional patients were treated in an extension phase. Thirteen of 22 patients (59%; 8/14 with FLT3-internal tandem duplication and 5/8 with FLT3-tyrosine kinase domain) achieved a complete remission/complete remission with incomplete blood count recovery. For the 17 patients included at the lower dose level, median overall, relapse-free and event-free survival were 1·6, 1·0 and 0·4 years, respectively. Four out of five analysed patients with relapse during maintenance therapy lost their initial FLT3 mutation, suggesting outgrowth of FLT3 wild-type subclones. © 2015 John Wiley & Sons Ltd.

Lacosamide: a review of its use as adjunctive therapy in the management of partial-onset seizures.

PubMed

Hoy, Sheridan M

2013-12-01

Lacosamide (Vimpat(®)) is a functionalized amino acid available orally (as a syrup or tablet) and as an intravenous infusion. It is believed to exert its antiepileptic effect by selectively enhancing the slow inactivation of voltage-gated sodium channels. Lacosamide is approved in several countries worldwide as an adjunctive therapy for the treatment of partial-onset seizures; however, prescribing regulations differ between countries. This article reviews the use of lacosamide as indicated in adults and adolescents (aged 16-18 years) in the EU, where it is approved in this patient population as an adjunctive therapy to other AEDs in the treatment of partial-onset seizures, with or without secondary generalization. In three randomized, double-blind, placebo-controlled, multicentre studies in adults and adolescents (aged 16-18 years) with partial-onset seizures, adjunctive therapy with oral lacosamide (administered for an initial titration period followed by 12 weeks' maintenance therapy) generally reduced the frequency of seizures to a significantly greater extent than placebo, with antiepileptic efficacy sustained following longer-term treatment (up to 8 years) in this patient population. Oral and intravenous lacosamide were generally well tolerated in clinical studies, with the majority of adverse events being mild or moderate in severity. Very common adverse reactions following adjunctive therapy with oral lacosamide included diplopia, dizziness, headache and nausea; the tolerability profile of intravenous lacosamide appeared consistent with that of oral lacosamide, although intravenous administration was associated with local adverse events, such as injection site discomfort or pain, irritation and erythema. Thus, oral and intravenous lacosamide as an adjunctive therapy to other AEDs provides a useful option in the treatment of patients with partial-onset seizures.

The precision segmented reflectors: Moderate mission figure control subsystem

A system concept for a space based segmented reflector telescope figure control subsystem is described. The concept employs a two phase architecture in which figure initialization and figure maintenance are independent functions. Figure initialization is accomplished by image sharpening using natural reference targets. Figure maintenance is performed by monitoring the relative positions and alignments of the telescope components using an optical truss. Actuation is achieved using precision positioners. Computer simulation results of figure initialization by pairwise segment coalignment/cophasing and simulated annealing are presented along with figure maintenance results using a wavefront error regulation algorithm. Both functions are shown to perform at acceptable levels for the class of submillimeter telescopes that are serving as the focus of this technology development effort. Component breadboard work as well as plans for a system testbed are discussed.

The dialysis outcomes quality initiative: history, impact, and prospects.

Rigorously developed clinical practice guidelines have the potential to improve patient outcomes. It is toward that end that the National Kidney Foundation (NKF) launched in March 1995 the Dialysis Outcome Quality Initiative (DOQI), an ambitious effort to develop evidence-based clinical practice guidelines for the care of patients with end-stage renal disease (ESRD). Independent, interdisciplinary work groups conducted a structured review of the content and methodologic rigor of all the published literature pertinent to four selected topics: hemodialysis adequacy, peritoneal dialysis adequacy, vascular access, and anemia. Following expert, organizational, and public review, the guidelines were issued in September and October 1997. An implementation plan that called for widespread dissemination of the guidelines and facilitation of adoption of them has resulted in their broad acceptance and Integration into quality improvement efforts. Additional guidelines on nutrition have recently been completed, while others on bone disease, hypertension, and hyperlipidemia are in various stages of planning or development. A major determinant of poor outcome of maintenance dialysis patients is the debilitated state of many individuals with ESRD at the time that they commence dialysis therapy. The recognition of this problem has stimulated an interest in extending the guidelines to management of patients with less severe renal insufficiency, well before they need renal replacement therapy; and to the early detection of renal insufficiency by a proteinuria and albuminuria risk assessment, detection, and elimination (PARADE) program. What started as an initiative to improve the quality of care of dialysis patients has evolved into a considerably expanded effort to making lives better for all individuals with any level of renal insufficiency.

Infliximab (IFX) is efficacious for induction and maintenance of remission in pediatric patients with moderate-to-severe inflammatory bowel disease (IBD). It has, however, not been studied in patients 7 years old and younger. Our aim was to characterize efficacy and safety of IFX therapy in this cohort. This was a retrospective study of patients with IBD ages 7 years and younger, treated with IFX between 1999 and 2011. Medical records were reviewed for age of diagnosis, disease phenotype, therapy, surgery, IFX infusion dates, dose, and intervals. Outcome measures included physician global assessment, corticosteroid requirement, and adverse events. Thirty-three children (ages 2.4-7 years) were included. Twenty patients had Crohn disease, 4 had ulcerative colitis, and 9 had indeterminate colitis. Maintenance of IFX therapy at 1, 2, and 3 years was 36%, 18%, and 12%, respectively. Patients of age 5 years and younger had the lowest rates of maintenance of therapy at 25% at year 1, and 10% at years 2 and 3 combined. Nine percent of all of the patients demonstrated response measured by the physician global assessment and were steroid free at 1 year. There were 8 infusion reactions. There were no malignancies, serious infections, or deaths. IFX demonstrated a modest response rate and a low steroid-sparing effect in patients with IBD 7 years old and younger. Although this is a limited study, there appears to be a trend for decreased sustained efficacy with IFX in this age group, particularly in children 5 years old and younger, when compared with the previously published literature in older children.

Acute lymphoblastic leukemia (ALL) is the most common form of paediatric cancer. Maintenance therapy as last treatment phase includes oral chemotherapy with methotrexate (MTX) and mercaptopurine (6-MP), self- or parent-administered at home, given for about 1 ½ years, and qualified as decisive for an optimum therapy outcome. The aim of our study was to analyze factors influencing the adherence of patients with ALL undergoing maintenance therapy and their families. A multi-method study was undertaken between 11/2011 and 10/2014 with patients surveyed by the Hannover Medical School outpatient clinic, including a questionnaire survey and qualitative interviews with parents as well as blood samples of the patients. 33 questionnaires, 27 interviews and blood samples of 26 patients could be analyzed. Only one third of the blood samples showed concentrations of the 6-MP active metabolite within the therapeutic reference range. Parents named the clinical doctor as their main advisor on medication intake. 36% (12/33) of the participants stated that medication intake has not always occurred the way medication was prescribed. Drug formulation and drug intake information could be identified as determinants of adherence. Parents' problems to obtain information are partly caused by different study results concerning the correct timing of the drug intake and drug interactions with milk products. Parents' information on drug therapy should be more consistent and the pharmaceutical formulations have to be adapted to patients' needs to improve adherence and thereby the chance of long-term remission. © Georg Thieme Verlag KG Stuttgart · New York.

Fluid therapy for septic shock resuscitation: which fluid should be used?

2015-01-01

Early resuscitation of septic shock patients reduces the sepsis-related morbidity and mortality. The main goals of septic shock resuscitation include volemic expansion, maintenance of adequate tissue perfusion and oxygen delivery, guided by central venous pressure, mean arterial pressure, mixed or central venous oxygen saturation and arterial lactate levels. An aggressive fluid resuscitation, possibly in association with vasopressors, inotropes and red blood cell concentrate transfusion may be necessary to achieve those hemodynamic goals. Nonetheless, even though fluid administration is one of the most common interventions offered to critically ill patients, the most appropriate type of fluid to be used remains controversial. According to recently published clinical trials, crystalloid solutions seem to be the most appropriate type of fluids for initial resuscitation of septic shock patients. Balanced crystalloids have theoretical advantages over the classic solutions, but there is not enough evidence to indicate it as first-line treatment. Additionally, when large amounts of fluids are necessary to restore the hemodynamic stability, albumin solutions may be a safe and effective alternative. Hydroxyethyl starches solutions must be avoided in septic patients due to the increased risk of acute renal failure, increased need for renal replacement therapy and increased mortality. Our objective was to present a narrative review of the literature regarding the major types of fluids and their main drawbacks in the initial resuscitation of the septic shock patients.

Cost-effectiveness analysis of adjunct VSL#3 therapy versus standard medical therapy in pediatric ulcerative colitis.

2011-11-01

Inflammatory bowel diseases (IBDs) are costly chronic gastrointestinal diseases, with pediatric IBD representing increased costs per patient compared to adult disease. Health care expenditures for ulcerative colitis (UC) are >$2 billion annually. It is not clear whether the addition of VSL#3 to standard medical therapy in UC induction and maintenance of remission is a cost-effective strategy. We performed a systematic review of the literature and created a Markov model simulating a cohort of 10-year-old patients with severe UC, studying them until 100 years of age or death. We compared 2 strategies: standard medical therapy versus medical therapy + VSL#3. For both strategies, we assumed that patients progressed through escalating therapies--mesalamine, azathioprine, and infliximab--before receiving a colectomy + ileal pouch anal anastamosis (IPAA) if the 3 medical therapy options were exhausted. The primary outcome measure was the incremental cost-effectiveness ratio (ICER), defined as the difference of costs between strategies for each quality-adjusted life-year (QALY) gained. One-way sensitivity analyses were performed on variables to determine the key variables affecting cost-effectiveness. Standard medical care accrued a lifetime cost of $203,317 per patient, compared to $212,582 per patient for medical therapy + VSL#3. Lifetime QALYs gained was comparable for standard medical therapy and medical therapy + VSL#3 at 24.93 versus 25.05, respectively. Using the definition of ICER <50,000/QALY as a cost-effective intervention, medical therapy + VSL#3 produced an ICER of $79,910 per QALY gained, making this strategy cost-ineffective. Sensitivity analyses showed that 4 key parameters could affect the cost-effectiveness of the 2 strategies: cost of colectomy + IPAA, maintenance cost after surgery, probability of developing pouchitis after surgery, and the quality of life after a colectomy + IPAA. High surgical and postsurgical costs, a high probability of developing pouchitis, and a low quality of life after a colectomy + IPAA could make adjunct VSL#3 use a cost-effective strategy. Given present data, adjunct VSL#3 use for pediatric UC induction and maintenance of remission is not cost-effective, although several key parameters could make this strategy cost-effective. The quality of life after an IPAA is the single most important variable predicting whether this procedure benefits patients over escalating standard medical therapy.

To evaluate the efficacy and safety of lacosamide administered as either first add-on or later add-on antiepileptic drug (AED) therapy for patients with uncontrolled partial-onset seizures (POS). In this open-label, multicentre trial, patients with POS initiated oral lacosamide (titrated to 400 mg/day) either as add-on to first AED monotherapy, or as later add-on to 1-3 concomitant AEDs after ≥ 2 previous AEDs. The primary efficacy variable was the proportion of patients achieving seizure freedom for the first 12 weeks of the 24-week Maintenance Phase. 456 patients received ≥ 1 dose of lacosamide (96 as first add-on, 360 as later add-on). In the first add-on cohort, 27/72 (37.5%) patients completed 12 weeks treatment and remained seizure-free; 18/68 (26.5%) remained seizure-free after 24 weeks. 64/91 (70.3%) patients achieved ≥ 50% reduction in seizure frequency during maintenance treatment. This was accompanied by a mean 7.1 ± 16.00 point improvement from Baseline in the Quality of Life Inventory in Epilepsy (QOLIE-31-P) total score for 24-week completers, with improvement reported in all subscales. Most common treatment-emergent adverse events (TEAEs) were dizziness (31.3%) and headache (13.5%). In the later add-on cohort, 39/261 (14.9%) and 29/249 (11.6%) patients remained seizure-free after completing 12 and 24 weeks' treatment, respectively. 178/353 (50.4%) patients achieved ≥ 50% reduction in seizure frequency during maintenance treatment. Mean change in QOLIE-31-P total score was 4.8 ± 14.74 points among 24-week completers. Common TEAEs were dizziness (33.6%), somnolence (15.0%) and headache (11.4%). Lacosamide initiated as first add-on treatment was efficacious and well tolerated in patients with uncontrolled POS. Copyright © 2015 The Authors. Published by Elsevier Ltd.. All rights reserved.

Telomeres at the ends of eukaryotic chromosomes play a critical role in maintaining the integrity and stability of the genome and participate in the initiation of DNA damage/repair responses. We performed a case-control study to evaluate the role of three SNPs (TERT-07, TERT-54 and POT1-03) in telomere maintenance genes previously found to be significantly associated with breast cancer risk. We used sister-sets obtained from the New York site of the Breast Cancer Family Registry (BCFR). Among the 313 sister-sets, there were 333 breast cancer cases and 409 unaffected sisters who were evaluated in the current study. We separately applied conditional logistic regression and generalized estimating equations (GEE) models to evaluate associations between the three SNPs and breast cancer risk within sister-sets. We examined the associations between genotype, covariates and telomere length among unaffected sisters using a GEE model. We found no significant associations between the three SNPs in telomere maintenance genes and breast cancer risk by both conditional logistic regression and GEE models, nor were these SNPs significantly related to telomere length. Among unaffected sisters, shortened telomeres were statistically significantly correlated with never hormone replacement therapy (HRT) use. Increased duration of HRT use was significantly associated with reduced telomere length. The means of telomere length were 0.77 (SD = 0.35) for never HRT use, 0.67 (SD = 0.29) for HRT use < 5 yrs and 0.59 (SD = 0.24) for HRT use ≥ 5 yrs after adjusting for age of blood donation and race and ethnicity. We found that exogenous hormonal exposure was inversely associated with telomere length. No significant associations between genetic variants and telomere length or breast cancer risk were observed. These findings provide initial evidence to understand hormonal exposure in the regulation of telomere length and breast cancer risk but need replication in prospective studies.

Adjustment of mercaptopurine and methotrexate maintenance therapy of acute lymphoblastic leukaemia by leucocyte count is confounded by natural variations. Cytotoxicity is primarily mediated by DNA-incorporated thioguanine nucleotides (DNA-TGN). The aim of this study was to establish whether DNA-TGN concentrations in blood leucocytes during maintenance therapy are associated with relapse-free survival. In this substudy of the NOPHO ALL2008 phase 3 trial done in 23 hospitals in seven European countries (Denmark, Estonia, Finland, Iceland, Lithuania, Norway, and Sweden), we analysed data from centralised and blinded analyses of 6-mercaptopurine and methotrexate metabolites in blood samples from patients with non-high-risk childhood acute lymphoblastic leukaemia. Eligible patients were aged 1·0-17·9 years; had been diagnosed with non-high-risk precursor B-cell or T-cell leukaemia; had been treated according to the Nordic Society of Pediatric Hematology and Oncology ALL2008 protocol; and had reached maintenance therapy in first remission. Maintenance therapy was (mercaptopurine 75 mg/m 2 once per day and methotrexate 20 mg/m 2 once per week, targeted to a leucocyte count of 1·5-3·0 × 10 9 cells per L). We measured DNA-TGN and erythrocyte concentrations of TGN nucleotides, methylated mercaptopurine metabolites, and methotrexate polyglutamates. The primary objective was the association of DNA-TGN concentrations and 6-mercaptopurine and methotrexate metabolites with relapse-free survival. The secondary endpoint was the assessment of DNA-TGN concentration and 6-mercaptopurine and methotrexate metabolites during maintenance therapy phase 2. Between Nov 26, 2008 and June 14, 2016, 1509 patients from the NOPHO ALL2008 study were assessed for eligibility in the DNA-TGN substudy, of which 918 (89%) of 1026 eligible patients had at least one DNA-TGN measurement and were included in the analyses. Median follow-up was 4·6 years (IQR 3·1-6·1). Relapse-free survival was significantly associated with DNA-TGN concentration (adjusted hazard ratio 0·81 per 100 fmol/μg DNA increase, 95% CI 0·67-0·98; p=0·029). In patients with at least five blood samples, erythrocyte concentrations of TGN, methylated mercaptopurine metabolites, and methotrexate polyglutamates were associated with DNA-TGN concentration (all p<0·0001). Our results suggest the need for intervention trials to identify clinically applicable strategies for individualised drug dosing to increase DNA-TGN concentration, and randomised studies to investigate whether such strategies improve cure rates compared with current dose adjustments based on white blood cell counts.

We hypothesized that the higher mortality for hemodialysis patients who live farther from the closest attending nephrologist compared with patients living closer might be due to lower quality of care. Population-based longitudinal study. All adult maintenance hemodialysis patients with measurements of quality-of-care indicators initiating hemodialysis therapy between January 2001 and June 2010 in Northern Alberta, Canada. Hemodialysis patients were classified into categories based on the distance by road from their residence to the closest nephrologist: ≤50 (referent), 50.1-150, 150.1-300, and >300 km. Quality-of-care indicators were based on published guidelines. Quality-of-care indicators at 90 days following initiation of hemodialysis therapy and, in a secondary analysis, at 1 year. Measurements were available for 1,784 patients. At baseline, the proportions of patients residing in each category were 69% for ≤50 km to closest nephrologist; 17%, 50.1-150 km; 7%, 150.1-300 km; and 7%, >300 km. Those who lived farther away from the closest nephrologist were less likely to have seen a nephrologist 90 days prior to the initiation of hemodialysis therapy (P for trend = 0.008) and were less likely to receive Kt/V of 1.2 (adjusted OR, 0.50; 95% CI, 0.30-0.84; P for trend = 0.01). Remote location also was associated with suboptimal levels of phosphate control (P for trend = 0.005). There were no differences in the prevalence of arteriovenous fistulas or grafts or hemoglobin levels across distance categories. Registry data with limited data for non-guideline-based quality indicators. Although several quality-of-care indicators were less common in remote-dwelling hemodialysis patients, these differences do not appear sufficient to explain the previously noted disparities in clinical outcomes by residence location.

Serotonin 1B (5-HT(1B)) heteroreceptors on nucleus accumbens shell (NAcSh) projection neurons have been shown to enhance the voluntary consumption of alcohol by rats, presumably by modulating the activity of the mesolimbic reward pathway. The present study examined whether increasing 5-HT(1B) receptors expressed on NAcSh projection neurons by means of virus-mediated gene transfer enhances ethanol consumption during the initiation or maintenance phase of drinking and alters the temporal pattern of drinking behavior. Animals received stereotaxic injections of viral vectors expressing either 5-HT(1B) receptor and green fluorescent protein (GFP) or GFP alone. Home cages equipped with a three-bottle (water and 6 and 12% ethanol) lickometer system recorded animals' drinking behaviors continuously, capturing either initiation or maintenance of drinking behavior patterns. Overexpression of 5-HT(1B) receptors during initiation increased consumption of 12% ethanol during both forced-access and free-choice consumption. There was a shift in drinking pattern for 6% ethanol with an increase in number of drinking bouts per day, although the total number of drinking bouts for 12% ethanol was not different. Finally, increased 5-HT(1B) expression induced more bouts with very high-frequency licking from the ethanol bottle sippers. During the maintenance phase of drinking, there were no differences between groups in total volume of ethanol consumed; however, there was a shift toward drinking bouts of longer duration, especially for 12% ethanol. This suggests that during maintenance drinking, increased 5-HT(1B) receptors facilitate longer drinking bouts of more modest volumes. Taken together, these results indicate that 5-HT(1B) receptors expressed on NAcSh projection neurons facilitate ethanol drinking, with different effects during initiation and maintenance of ethanol-drinking behavior.

To describe primary care physicians' (PCPs) perceptions of patient reactions and concerns about insulin initiation and identify opportunities for increased support. Cross-sectional, online survey of PCPs prescribing basal insulin to adults with type 2 diabetes mellitus (T2DM). PCPs were identified from administrative claims of a large commercial health plan and descriptive results of PCP responses were reported. PCPs (N=100) treated an average of 17 patients receiving insulin during a typical week. More than 85% of insulin initiation recommendations originated with PCPs. Most offered glucose monitoring instructions (96%) and advice on diet, exercise, and diabetes management (96%); 35% provided insulin titration algorithms; 93% reported that patients often or always took their insulin daily within 3 months of initiation; 31% of PCPs reported monthly office contacts with patients for the first 3 months; 16% reported no outreach efforts; fewer than 20% connected patients with support groups. When starting basal insulin, PCPs reported patients feeling personal failure regarding their diabetes treatment (33% often/always) and lacking confidence in their ability to manage insulin therapy (38% often/always). Study results identify additional opportunities for assisting patients in making the transition to insulin, including more frequent direct outreach to monitor insulin usage.

Evidence-based psychological treatments (EBPTs) are clusters of interventions, but it is unclear how providers actually implement these clusters in practice. A disaggregated measure of EBPTs was developed to characterize clinicians' component-level evidence-based practices and to examine relationships among these practices. Survey items captured components of evidence-based treatments based on treatment integrity measures. The Web-based survey was conducted with 75 U.S. Department of Veterans Affairs (VA) substance use disorder (SUD) practitioners and 149 non-VA community-based SUD practitioners. Clinician's self-designated treatment orientations were positively related to their endorsement of those EBPT components; however, clinicians used components from a variety of EBPTs. Hierarchical cluster analysis indicated that clinicians combined and organized interventions from cognitive-behavioral therapy, the community reinforcement approach, motivational interviewing, structured family and couples therapy, 12-step facilitation, and contingency management into clusters including empathy and support, treatment engagement and activation, abstinence initiation, and recovery maintenance. Understanding how clinicians use EBPT components may lead to improved evidence-based practice dissemination and implementation. Published by Elsevier Inc.

Hyperthyroidism and the management of atrial fibrillation.

2002-06-01

Atrial fibrillation is often induced in patients with hyperthyroidism and may trigger heart failure. Its prevalence and outcome were examined to obtain up-to-date information. Persistent atrial fibrillation was observed in approximately 1.7% of new hyperthyroid patients. It occurs more frequently in males (2.86%) than in females (1.36%), even though the number of male hyperthyroid patients is only one fifth of female patients. The rate increased with age, being 8% in the patients older than 70 years old. The initial treatment is to control the heart rate with routine pharmacologic therapy and to start antithyroid therapy as quickly as possible. Attempted cardioversion should be deferred until approximately the fourth month of maintaining a euthyroid state, because more than 56% of atrial fibrillation spontaneously reverts to sinus rhythm when the thyroid hormone levels start to decline. Elective cardioversion for those whose atrial fibrillation persists is highly effective and sinus rhythm maintenance rates were 56.7% and 47.6% at the 10th and the 14th year, respectively, even though the duration of atrial fibrillation prior to cardioversion was extremely long (35.0 +/- 29.0 months).

Photodynamic therapy (PDT) of dysplasia and early cancer of the esophagus could show good results in the potential of ablation. Unfortunately, the existing expensive and temperamental dye laser systems foiled a broad clinical use. In this pilot study, we investigated the feasibility of an inexpensive and maintenance-free diode laser system for PDT of dysplasia and early cancer in Barrett's esophagus. Eight patients with Barrett's esophagus and/or early cancer were treated. As light source we used a diode laser system with a maximum power output of 2 W and a wavelength of 633 +/- 3 nm. One patient was treated initially with Photosan-3, seven patients received 5-aminolevulinic acid. In all patients we could achieve reduction in length and/or histologically proven downgrading. In three quarters of the patients, complete eradication of adenocarcinoma could be attained. Columnar-lined metaplastic epithelium could also be completely eradicated. PDT using a diode laser system is comparably effective in Barrett's esophagus/early cancer as PDT with dye laser systems. PDT is a gentle and effective technique with little side effects.

The development of facial lipoatrophy as a result of highly active antiretroviral therapy (HAART) used to treat patients with human immunodeficiency virus (HIV) has adversely affected patient quality of life and compliance with therapy. Thanks to modern pharmacotherapies, HIV can now be viewed as a chronic disease; however, this welcome change has exacerbated the effect of facial lipoatrophy since HIV-infected patients can now expect to live longer and healthier lives but remain subject to public scrutiny of their ongoing disease state. Sculptra (Dermik Laboratories, Berwyn, PA, USA) has recently been introduced in the USA for correction of the appearance of facial lipoatrophy. The device affords long-lasting restoration while still being non-permanent, thus providing an extended but adjustable cosmetic effect. The safety profile of this product has been observed in four investigator-initiated clinical trials of more than 250 HIV patients and in numerous investigator reports, with no serious adverse events or infections deemed associated with the product. Maintenance of the excellent safety profile for this injectable device requires adherence to a novel technique and appreciation of its unique attributes.

Recalcitrant eosinophilic pustular folliculitis of Ofuji with palmoplantar pustulosis: dramatic response to narrowband UVB phototherapy.

Eosinophilic pustular folliculitis of Ofuji is a recalcitrant disease typified by non-infective eosinophilic spongiosis involving the infundibular region of the hair follicle. We present a case of a 49-year-old Chinese man with known palmoplantar pustulosis and acrodermatitis continua of Hallopeau which was promptly resolved with methotrexate therapy. He returned with an erythematous papulopustular eruption with coalescence to annular plaques, occurring over the face, chest and back with active palmoplantar pustulation. Histology from skin biopsy of the palmar lesion was in keeping with palmoplantar psoriasis, while biopsy of the facial and truncal lesions revealed florid perifollicular eosinophilic congregation diagnostic of eosinophilic pustular folliculitis of Ofuji. Indomethacin was initiated with partial improvement of lesions with cyclical flares. A trial of narrowband ultraviolet-B phototherapy at a frequency of thrice weekly achieved sustained clearance of both eosinophilic pustular folliculitis and palmoplantar lesions. Indomethacin was tailed down and eventually discontinued with maintenance of narrowband ultraviolet-B therapy; this achieved successful control of the disease. © 2012 John Wiley & Sons A/S.

Ulcerative colitis (UC) is defined as a chronic inflammatory condition causing continuous mucosal inflammation of the colon without granulomas on biopsy. It affects the rectum, and, to a variable extent, the colon in continuity and is characterized by a relapsing and remitting course. Oral 5-aminosalicylic acid (5-ASA) regimens are recommended as first-line induction therapy for mild to moderately active pediatric UC and for maintenance of remission regardless of other initial treatments. In large clinical trials in adults, mesalamine intolerance was found in 2-5 % of the patients. We present a case of an 8-year-old female patient with intolerance to mesalamine and proctitis resistant to conventional therapy who responded to rectal tacrolimus treatment. The patient started with a dose of 2 mg/day at night with an excellent response. She reported feeling better than any of the previously prescribed treatments and without feeling the discomfort of previously administered enemas. After four weeks of treatment, the dose was reduced to 2 mg/week with no relapses. Tacrolimus suppositories were very well tolerated, and no adverse effects have been reported. Although only very little data has been published, rectal tacrolimus seems to be safe and of efficacy in ulcerative proctitis resistant to standard therapy.

Acute kidney injury: not just acute renal failure anymore?

PubMed

Dirkes, Susan

2011-02-01

Until recently, no uniform standard existed for diagnosing and classifying acute renal failure. To clarify diagnosis, the Acute Dialysis Quality Initiative group stated its consensus on the need for a clear definition and classification system of renal dysfunction with measurable criteria. Today the term acute kidney injury has replaced the term acute renal failure, with an understanding that such injury is a common clinical problem in critically ill patients and typically is predictive of an increase in morbidity and mortality. A classification system, known as RIFLE (risk of injury, injury, failure, loss of function, and end-stage renal failure), includes specific goals for preventing acute kidney injury: adequate hydration, maintenance of renal perfusion, limiting exposure to nephrotoxins, drug protective strategies, and the use of renal replacement therapies that reduce renal injury.

HIV Tat/P-TEFb Interaction: A Potential Target for Novel Anti-HIV Therapies.

Transcription is a crucial step in the life cycle of the human immunodeficiency virus type 1 (HIV 1) and is primarily involved in the maintenance of viral latency. Both viral and cellular transcription factors, including transcriptional activators, suppressor proteins and epigenetic factors, are involved in HIV transcription from the proviral DNA integrated within the host cell genome. Among them, the virus-encoded transcriptional activator Tat is the master regulator of HIV transcription. Interestingly, unlike other known transcriptional activators, Tat primarily activates transcriptional elongation and initiation by interacting with the cellular positive transcriptional elongation factor b (P-TEFb). In this review, we describe the molecular mechanism underlying how Tat activates viral transcription through interaction with P-TEFb. We propose a novel therapeutic strategy against HIV replication through blocking Tat action.

Human Papillomaviruses As Therapeutic Targets in Human Cancer

Hellner, Karin; Münger, Karl

2011-01-01

Cervical carcinomas are almost universally associated with high-risk human papillomavirus (HPV) infections, and are a leading cause of cancer death in women worldwide. HPV oncoproteins contribute to cancer initiation and progression and their expression is necessary for the maintenance of the transformed state. The fact that the initiating oncogenic insult, infection with a high-risk HPV and viral oncoprotein expression, is common to almost all cervical cancers offers unique opportunities for prevention, early detection, and therapy. The potential for prevention has been realized by introduction of prophylactic vaccines that are to prevent transmission of specific high-risk HPVs. Given, however, that these vaccines have no therapeutic efficacy and HPV-associated cervical cancers arise years if not decades after the initial infection, it has been estimated that there will be no measurable decline of HPV-associated tumors before 2040. Cervical cancer alone will be diagnosed in more than 375,000 US women between now and 2040. Other HPV-associated anogenital and head and neck cancers are predicted to afflict another 700,000 men and women over this time period. Hence, therapeutic efforts to combat high-risk HPV-associated disease remain of critical importance. PMID:21220591

Smoking behaviour and its course is influenced by personality factors. Affective temperaments could allow a more specific framework of the role trait affectivity plays in this seriously harmful health-behaviour. The aim of our study was to investigate if such an association exists in an ageing population with a special emphasis on gender differences. 459 primary care patients completed the TEMPS-A, Beck Depression Inventory (BDI) and Hamilton Anxiety Rating Scale (HAM-A). Subjects were characterized according to their smoking behaviour as current, former or never smokers. Univariate analysis ANOVA and logistic regression were performed to analyse differences in the three smoking subgroups to predict smoking initiation and maintenance. Current smokers were younger and less educated than former or never smokers. Males were more likely to try tobacco during their lifetime and were more successful in cessation. Depressive, cyclothymic and irritable temperament scores showed significant differences between the three smoking subgroups. Irritable temperament was a predictor of smoking initiation in females whereas depressive temperament predicted smoking maintenance in males with a small, opposite effect of HAM-A scores independent of age, education, lifetime depression and BDI scores. Whereas smoking initiation was exclusively predicted by a higher BDI score in males, smoking maintenance was predicted by younger age and lower education in females. The cross-sectional nature of the study design may lead to selective survival bias and hinder drawing causal relationships. Affective temperaments contribute to smoking initiation and maintenance independently of age, education, and depression. The significant contribution of depressive temperament in males and irritable temperament in females may highlight the role of gender-discordant temperaments in vulnerable subgroups.

This was a phase IV, multicenter, open-label, 12-14-month study to assess clinical recurrence in patients with ulcerative colitis (UC) who received maintenance treatment with MMX Multi Matrix System (MMX) mesalamine. A secondary outcome was the relationship between long-term efficacy and adherence. Patients with quiescent UC (no rectal bleeding; 0-1 bowel movements more than normal per day) were enrolled directly into a 12-month maintenance phase of the study during which they received MMX mesalamine 2.4 g/day given once daily (QD). Patients with active, mild-to-moderate UC at screening were enrolled into a 2-month acute phase; those who achieved quiescence could continue into the maintenance phase. The primary endpoint was clinical recurrence at Month 6. Of the 290 patients enrolled, 208 entered the maintenance phase; 152 directly and 56 via the acute phase. Following 6 and 12 months of treatment, 76.5% and 64.4% of evaluable patients, respectively, were recurrence-free. The majority of evaluable patients at Month 6 (81.6%) and Month 12 (79.4%) in the maintenance phase were ≥ 80% adherent to MMX mesalamine. At Month 6, clinical recurrence was observed in 20.6% of patients who were ≥ 80% adherent and 36.1% of patients with <80% adherence (P = 0.05 [post-hoc chi-square analysis]); 31.2% and 52.5% at Month 12 (P = 0.01 [post-hoc chi-square analysis]). MMX mesalamine 2.4 g/day QD is effective for maintaining quiescence in patients with UC. Furthermore, adherence to prescribed treatment yielded lower rates of clinical recurrence. Continued education regarding the importance of long-term 5-aminosalicylic acid therapy is warranted. Copyright © 2011 Crohn's & Colitis Foundation of America, Inc.

The aim of this study was to evaluate the response characteristics of vincristine, adriamycin and dexamethasone (VAD) as a first-line chemotherapy and to determine the efficacy of maintenance alpha-interferon (alpha-IFN) in multiple myeloma (MM). Between January 1985 and December 1994, a prospective trial was performed in stage II and III MM patients. The study population received only VAD with no maintenance therapy before 1990 (n=31), and those recruited after 1990 (n=33) were planned to be maintained with alpha-IFN (5 mU, 3 times per wk) during the plateau to a maximum of 2 yr. Median follow-up duration (44 vs. 39 months), time to response (3.4 vs. 3.5 months) and rate of objective response (61.3%, 19/31 and 63.6%, 21/33) were similar in VAD-only and VAD+IFN groups, respectively. The survival analyses revealed higher median progression-free (39.6 vs. 12 months) and overall survival (65+ vs. 24 months) durations in VAD+IFN group compared to VAD-only group. VAD regimen was well tolerated and IFN-related side effects were reversible. These findings denote that IFN maintenance prolongs the duration of response obtained by VAD.

The evolution of stem-cell transplantation in multiple myeloma.

2018-05-01

Autologous stem-cell transplantation (ASCT) remains an integral part of treatment for previously untreated, and may have value in the treatment of relapsed patients with, multiple myeloma (MM). The addition of novel agents like immunomodulators and proteasome inhibitors as induction therapy before and as consolidation/maintenance therapy after ASCT has led to an improvement in complete response (CR) rates, progression-free survival (PFS) and overall survival (OS). With advances in supportive care, older patients and patients with renal insufficiency are now able to safely undergo the procedure. The data concerning the timing of ASCT (early in the disease course or at first relapse), single versus tandem (double) ASCT and the role and duration of consolidation and maintenance therapy post ASCT remain conflicting. This review aims to discuss the evolution of stem-cell transplant over the past 3 decades and its current role in the context of newer, safer and more effective therapeutic agents.

Electroconvulsive therapy: a life course approach for recurrent depressive disorder

2015-01-01

We describe the case of an 89-year-old woman (deceased) with a 60-year history of recurrent depressive disorder treated with electroconvulsive therapy (ECT). It is estimated that she received up to 400 ECTs over her life course as her symptoms would not respond to oral medication. Despite extensive exposure to ECT, there was only minimal cognitive impairment and an excellent safety record, even in later life, as she became increasingly frail from multiple comorbidities. Over the years, there has been a drive to reduce the frequency of ECT administration. However, this case illustrates how in some patients ECT may be vital for acute episodes of severe depression as well as for maintenance therapy. This case report adds to observational evidence that maintenance ECT may be an underused treatment for recurrent depression and also recommends that greater emphasis be given to incorporating carers’ views when planning individualised treatment approaches.

2012-01-01

Methadone maintenance therapy (MMT) in China is facing challenges such as high relapse rates and low coverage. The study assessed factors influencing MMT utilization among opiate users. In-depth interviews were conducted among 30 opiate users in 2008 to ascertain the barriers against seeking MMT. Data were analyzed using ATLAS.ti. Barriers to the treatment included requirement of registration with police, perceived discrimination, logistic difficulties, side effects, fear of being addicted to another drug, lack of additional services, and economic burden. The result suggests the need for structural changes such as improving comprehensive services, simplifying application procedure, and enhancing referral system. The study's limitations are noted.

Most patients with coronary artery disease and peripheral vascular disease are on long-term antiplatelet therapy and dual therapy. Achieving a balance between ischemic and bleeding risk remains an important factor in managing patients on antiplatelet therapy. For most outpatient surgical procedures, maintenance and continuation of this therapy are recommended. Consultation with the patient's cardiologist, physician, and/or vascular surgeon is always recommended before interrupting or withholding this treatment modality. Copyright © 2016 Elsevier Inc.

Inflammation contributes to growth failure associated with inflammatory bowel diseases. Anti-TNFα therapy induces sustained remission and short-term improvements in height velocity and/or height standard deviation score (H-SDS) patients with Crohn's disease. The purpose of this study was to evaluate growth and adult height in patients with Crohn's disease taking maintenance infliximab or adalimumab therapy.This university-hospital based retrospective study included 61 patients, with a median follow-up of 2.6 years (2.0; 3.3). 38 patients (62%) reached their adult height. H-SDS was collected at diagnosis and together with disease activity markers (Harvey-Bradshaw Index, albumin, and C-reactive protein) at treatment initiation (baseline), and follow-up completion. Wilcoxon's signed-rank test was chosen for comparisons. Median H-SDS decreased from diagnosis to baseline (-0.08 [-0.73; +0.77] to -0.94 [-1.44; +0.11], p<0.0001) and then increased to follow-up completion (-0.63 [-1.08; 0.49], p = 0.003 versus baseline), concomitantly with an improvement in disease activity. Median adult H-SDS was within the normal range (-0.72 [-1.25; +0.42]) but did not differ from baseline H-SDS and was significantly lower than the target H-SDS (-0.09 [-0.67; +0.42], p = 0.01). Only 2 (6%) males had adult heights significantly below their target heights (10.5 and -13.5 cm [-1.75 and -2.25 SD]). In conclusion, anti-tumor necrosis factor α (TNF) therapy prevented loss of height without fully restoring the genetic growth potential in this group of patients with CD. Earlier treatment initiation might improve growth outcomes in these patients.

Background & objectives: Chronic kidney disease (CKD) is commonly complicated by secondary hyperparathyroidism (SHPT), leading to increased risk of morbidity and mortality. SHPT is a progressive disease often requiring long-term therapy to control parathyroid hormone (PTH) and mineral imbalances. Vitamin D sterols and phosphate binders, used as traditional therapies to lower PTH and phosphorus, may provide inadequate long-term control for many dialysis patients. Cinacalcet, by simultaneously lowering PTH, calcium, phosphorus, and calcium-phosphorus levels, may maintain PTH and mineral balance in these individuals. However, as with traditional therapies, long-term data are limited. Design, setting, participants, & measurement: Dialysis subjects from at least one of five lead-in studies (double-blind placebo-controlled, including one extension trial) completing up to 52 wk of either cinacalcet or placebo were eligible for this open-label extension study, including an 8-wk dose titration (initiated at 30 mg/d), followed by 24-wk maintenance and up to 132 wk of follow-up. Final efficacy analysis was at week 180. Results: Three hundred thirty-four of 589 enrolled subjects received cinacalcet from the beginning of the lead-in study. Weekly median PTH values were ≤300 pg/ml (weeks 16 through 180) and median Ca×P values were ≤55 mg2/dl2 (weeks 4 through 180). Similar results were exhibited in the 255 subjects who initially received placebo. Among the patients exposed to cinacalcet from the beginning of the lead-in study, 3% of subjects exhibited treatment-related serious adverse events. Conclusions: Cinacalcet effectively maintained PTH, Ca and P reductions in dialysis subjects for up to 180 wk. PMID:19696213

Patient attrition is common among people enrolled in methadone maintenance treatment (MMT) programs and most pronounced during the first year of treatment. However, the experiences of patients initiating MMT have been overlooked in the literature. This study explores experiences of MMT initiation among MMT patients, focusing on contextual influences on MMT initiation and perceptions of MMT and their subsequent influence on treatment retention. Semi-structured qualitative interviews were conducted with 39 MMT patients in Vancouver, Canada. Individuals reporting enrolment in MMT were recruited from within two ongoing cohort studies comprised of people who use drugs. Interview transcripts were analysed using an inductive and iterative approach. Two groups of MMT initiators were identified: (i) 'crisis initiators' prescribed methadone following critical transition events, such as incarceration or pregnancy; and (ii) 'everyday initiators' enrolled in MMT as part of routine healthcare utilisation. While most 'crisis initiators' and some 'everyday initiators' described experiencing coercion during MMT initiation, 'crisis initiators' were further subjected to the coercive leveraging of their vulnerability to motivate 'consent' for MMT. 'Crisis initiators' developed negative views towards MMT and were more likely to discontinue treatment. Long-standing patient-provider relationships and open dialogue were associated with more positive views regarding MMT, regardless of the circumstances of initiation. Findings underscore the need for clear and effective communication regarding treatment regimens and expectations during MMT initiation. Furthermore, training in trauma-informed care may help reduce perceptions of coercion and rates of early treatment termination. [Damon W, Small W, Anderson S, Maher L, Wood E, Kerr T, McNeil R.

Cognitive behavioural therapy is an effective treatment for depression. However, one third of the patients do not respond satisfactorily, and relapse rates of around 30 % within the first post-treatment year were reported in a recent meta-analysis. In total, 30-50 % of remitted patients present with residual symptoms by the end of treatment. A common residual symptom is rumination, a process of recurrent negative thinking and dwelling on negative affect. Rumination has been demonstrated as a major factor in vulnerability to depression, predicting the onset, severity, and duration of future depression. Rumination-focused cognitive behavioural therapy is a psychotherapeutic treatment targeting rumination. Because rumination plays a major role in the initiation and maintenance of depression, targeting rumination with rumination-focused cognitive behavioural therapy may be more effective in treating depression and reducing relapse than standard cognitive behavioural therapy. This study is a two-arm pragmatic randomised controlled superiority trial comparing the effectiveness of group-based rumination-focused cognitive behaviour therapy with the effectiveness of group-based cognitive behavioural therapy for treatment of depression. One hundred twenty-eight patients with depression will be recruited from and given treatment in an outpatient service at a psychiatric hospital in Denmark. Our primary outcome will be severity of depressive symptoms (Hamilton Rating Scale for Depression) at completion of treatment. Secondary outcomes will be level of rumination, worry, anxiety, quality of life, behavioural activation, experimental measures of cognitive flexibility, and emotional attentional bias. A 6-month follow-up is planned and will include the primary outcome measure and assessment of relapse. The clinical outcome of this trial may guide clinicians to decide on the merits of including rumination-focused cognitive behavioural therapy in the treatment of depression in outpatient services.

IMPORTANCE Waldenström macroglobulinemia (WM), an IgM-associated lymphoplasmacytic lymphoma, has witnessed several practice-altering advances in recent years. With availability of a wider array of therapies, the management strategies have become increasingly complex. Our multidisciplinary team appraised studies published or presented up to December 2015 to provide consensus recommendations for a risk-adapted approach to WM, using a grading system. OBSERVATIONS Waldenström macroglobulinemia remains a rare, incurable cancer, with a heterogeneous disease course. The major classes of effective agents in WM include monoclonal antibodies, alkylating agents, purine analogs, proteasome inhibitors, immunomodulatory drugs, and mammalian target of rapamycin inhibitors. However, the highest-quality evidence from rigorously conducted randomized clinical trials remains scant. CONCLUSIONS AND RELEVANCE Recognizing the paucity of data, we advocate participation in clinical trials, if available, at every stage of WM. Specific indications exist for initiation of therapy. Outside clinical trials, based on the synthesis of available evidence, we recommend bendamustine-rituximab as primary therapy for bulky disease, profound hematologic compromise, or constitutional symptoms attributable to WM. Dexamethasone-rituximab-cyclophosphamide is an alternative, particularly for nonbulky WM. Routine rituximab maintenance should be avoided. Plasma exchange should be promptly initiated before cytoreduction for hyperviscosity-related symptoms. Stem cell harvest for future use may be considered in first remission for patients 70 years or younger who are potential candidates for autologous stem cell transplantation. At relapse, retreatment with the original therapy is reasonable in patients with prior durable responses (time to next therapy≥3 years) and good tolerability to previous regimen. Ibrutinib is efficacious in patients with relapsed or refractory disease harboring MYD88 L265P mutation. In the absence of neuropathy, a bortezomib-rituximab–based option is reasonable for relapsed or refractory disease. In select patients with chemosensitive disease, autologous stem cell transplantation should be considered at first or second relapse. Everolimus and purine analogs are suitable options for refractory or multiply relapsed WM. Our recommendations are periodically updated as new, clinically relevant information emerges. PMID:28056114

Induction, maintenance, and amplification of tumor-protective immunity after cytokine gene therapy is essential for the clinical success of immunotherapeutic approaches. We investigated whether this could be achieved by single-chain IL-12 (scIL-12) gene therapy followed by tumor-targeted IL-2 using a fusion protein containing a tumor-specific recombinant anti-ganglioside GD2 antibody and IL-2 (ch14.18-IL-2) in a poorly immunogenic murine neuroblastoma model. Herein, we demonstrate the absence of liver and bone marrow metastases after a lethal challenge with NXS2 wild-type cells only in mice (five of six animals) vaccinated with scIL-12-producing NXS2 cells and given a booster injection of low-dose ch14.18-IL-2 fusion protein. This tumor-protective immunity was effective 3 months after initial vaccination, in contrast to control animals treated with a nonspecific fusion protein or an equivalent mixture of antibody and IL-2. Only vaccinated mice receiving the tumor-specific ch14.18-IL-2 fusion protein revealed a reactivation of CD8+ T cells and subsequent MHC class I-restricted tumor target cell lysis in vitro. The sequential increase in the usage of TCR chains Vβ11 and -13 in mouse CD8+ T cells after vaccination and amplification with ch14.18-IL-2 suggests that the initial polyclonal CD8+ T cell response is effectively boosted by targeted IL-2. In conclusion, we demonstrate that a successful boost of a partially protective memory T cell immune response that is induced by scIL-12 gene therapy could be generated by tumor-specific targeting of IL-2 with a ch14.18-IL-2 fusion protein. This approach could increase success rates of clinical cancer vaccine trials. PMID:10411920

Associations between the effects of SCN1A, SCN2A, ABCC2 and UGT2B7 genetic polymorphisms and oxcarbazepine (OXC) maintenance doses in Han Chinese epileptic patients were investigated. Genetic polymorphisms were detected in 184 epileptic patients receiving OXC monotherapy by high-resolution melting curve and TaqMan method. Carriers of the SCN1A IVS5-91G>A, UGT2B7 c.802T>C and ABCC2 c.1249G>A variant alleles required significantly higher OXC maintenance doses than noncarriers (p < 0.05). Corresponding relative ln (concentration-dose ratios) values for SCN1A IVS5-91 variants differed by the genotypic order GG > GA > AA. SCN1A, UGT2B7 and ABCC2 genetic polymorphisms are associated with OXC maintenance doses and may be useful for the personalization of OXC therapy in epileptic patients. Further studies are needed.

Parkinson's disease (PD) is the second most common neurological disease affecting older adults. Consequently, this disease should be a focus among payers, with increasing utilization of newer premium-priced patent-protected add-on therapies to stabilize or even improve motor function over time. However, expenditure can be moderated by reforms. Consequently, there is a need to assess the influence of these reforms on the prescribing efficiency for drugs to treat PD in Croatia before proposing additional measures. Prescribing efficiency is defined as increasing the use of add-on therapies for similar expenditure. An observational retrospective study of the Croatian Institute for Health Insurance database of drugs to treat patients with PD in Croatia from 2000 to 2010 was carried out, with utilization measured in defined daily doses (defined as the average maintenance dose of a drug when used in its major indication in adults). The study years were chosen to reflect recent reforms. Only reimbursed expenditure is measured from a health insurance perspective. Utilization of drugs to treat PD increased by 218% between 2000 and 2010. Reimbursed expenditure increased by 360%, principally driven by increasing utilization of premium-priced patent-protected add-on therapies, including ropinirole and pramipexole. However, following recent reforms, reducing expenditure/defined daily dose for the different drugs, as well as overall expenditure, stabilized reimbursed expenditure between 2005 and 2010. Treatment of PD is complex, and add-on therapies are needed to improve care. Reimbursed expenditure should now fall following stabilization, despite increasing volumes, as successive add-on therapies lose their patents, further increasing prescribing efficiency.

Treatment of Plantar Fasciitis With Radial Soundwave "Early" Is Better Than After 6 Months: A Pilot Study.

PubMed

Saxena, Amol; Hong, Brian K; Yun, Andrew S; Maffulli, Nicola; Gerdesmeyer, Ludger

Extracorporeal shock wave therapy/radial soundwave therapy has been predominantly used for chronic or recalcitrant plantar fasciitis with strong scientific evidence of reliable outcomes. Most of the studies included patients with plantar fasciitis with symptoms >6 months in duration. Only 2 known studies have investigated acute plantar fasciitis, which is <6 weeks in duration. They both found suboptimal results for the use of extracorporeal shock wave therapy. To the best of our knowledge, no studies have investigated radial soundwave therapy for the subacute stage or early stage of plantar fasciitis. Data were prospectively collected from 28 eligible patients who underwent radial soundwave therapy (RSWT) during a 9-month period in 2014. Of the 28 subjects, 14 were enrolled in the "early group" with a symptom duration of <3 months and 14 in the "standard/control" group with a symptom duration of >6 months. The pretreatment and posttreatment visual analog scale scores, Roles-Maudlsey scores, and activity level were recorded and compared. The early implementation of RSWT yielded comparable outcomes when compared with the standard group. RSWT is a valid treatment modality that can be implemented soon after the initial treatment options or first-phase treatment options have failed. Early treatment is more likely to allow for maintenance of patients' activity level. Also, waiting 6 months to treat plantar fasciitis with RSWT results in delays and inferior results. Early treatment is better for active and athletic patients. Copyright © 2017 American College of Foot and Ankle Surgeons. Published by Elsevier Inc. All rights reserved.

Cancer treatment symptoms play a major role in determining the health of children with cancer. Symptom toxicity often results in complications, treatment delays, and therapy dose reductions that can compromise leukemia therapy and jeopardize chances for long-term survival. Critical to understanding symptom experiences during treatment is the need for exploration of "why" inter-individual symptom differences occur; this will determine who may be most susceptible to treatment toxicities. This study examined specific symptom trajectories during the first 18 months of childhood leukemia treatment. Symptom measures included fatigue, sleep disturbances, pain, nausea, and depression. Symptom trajectories of 236 children with leukemia three to 18 years old were explored prospectively over four periods: initiation of post-induction therapy, four and eight post-induction therapy, and the last time point was at the beginning of maintenance/continuation therapy. Latent class growth analysis was used to classify patients into distinctive groups with similar symptom trajectories based on patients' response patterns on the symptom measures over time. Three latent classes of symptom trajectories were identified and classified into mild, moderate, and severe symptom trajectories. The only demographic characteristic with a significant relationship to membership in the latent class symptom trajectories was race/ethnicity. All other demographic characteristics including leukemia risk levels showed no significant relationships. This study is unique in that groups of patients with similar symptoms were identified rather than groups of symptoms. Further research using latent class growth analysis is needed.

2007-03-01

Numerous reports have dichotomized responses after clopidogrel therapy using varying definitions and platelet tests in patients immediately after acute vascular events; however, no large study has assessed platelet characteristics in outpatients receiving long-term treatment for more than 30 days with the maintenance dose (75 mg/d) of clopidogrel. The aim of this study was to describe the responses of ex vivo measures of platelet aggregation and activation to long-term clopidogrel therapy in a large population of outpatients after coronary stenting or ischemic stroke. We conducted a secondary post hoc analysis of a data set represented by presumably compliant patients after coronary stenting (n = 237) or a documented ischemic stroke (n = 122) treated with clopidogrel-and-aspirin combination antiplatelet therapy. The mean duration of treatment was 5.8 months (range 1-21 months). Every patient exhibited a significant inhibition of adenosine diphosphate-induced platelet aggregation (mean 52.9%, range 36%-70%) as compared with the preclopidogrel measures. Inhibition of aggregation strongly correlated with a diminished expression of PECAM-1 (platelet/endothelial cell adhesion molecule 1, r = 0.75), glycoprotein IIb/IIIa (r = 0.62), and PAR-1 (protease-activated receptor 1, r = 0.71). None of the patients developed hyporesponsiveness (reduction from the baseline <15%) or profound inhibition (residual platelet activity <10%). In contrast to the wide variability of responses that exists in the acute setting, long-term therapy with clopidogrel leads to consistent and much less variable platelet inhibition. Lack of nonresponse and profound inhibition with clopidogrel allow for the maintenance of a delicate balance between proven efficacy and acceptable bleeding risks for long-term secondary prevention in outpatients after acute vascular events.

Culinary Grief Therapy: Cooking for One Series.

Nickrand, Heather L; Brock, Cara M

2017-02-01

Although loss of loved ones is a universal experience, individuals who experience this loss grieve in different ways. Complicated grief involves the development of trauma symptoms, such as flashbacks, anxiety, and fear associated with daily activities after a death that disrupts the healthy grieving process. Daily activities such as eating, meal planning, grocery shopping, managing finances, and household maintenance can become painful and isolating for those experiencing complicated grief. Cognitive behavioral therapy is used to address irrational beliefs, feelings of depression or anger, and avoidance or numbing behaviors with a goal of leading the individual to adapting to a life, which no longer includes the lost loved one. As part of the bereavement counseling program in a hospice, a need was identified in individuals who had lost loved ones and were having difficulty with adjusting to meal planning, grocery shopping, and cooking for one. To address this need for grief counseling centered on meal planning, grocery shopping, meal preparations, and eating meals alone, "Culinary Grief Therapy: Cooking for One Series" was developed with a local Culinary Arts Program. Partnering with a local community college culinary arts program, the Cooking for One Series provides an interactive venue for cognitive behavioral therapy centered on meal planning and meal times. Along with demonstrations and hands-on experiences, participants are engaged in bereavement counseling with hospice staff. Initial reactions to Culinary Grief Therapy have been positive. Many attendees have participated in multiple workshops, and the number of participants grows for each offering. Culinary Grief Therapy is a novel approach to the needs of those experiencing the loss of a loved one and may reduce or prevent complicated grief associated with meal planning, grocery shopping, and cooking for one.

The aim of this study was to evaluate the relationship between changes in proton magnetic resonance spectroscopy (1H-MRS) parameters at the start of the index episode recovery phase and at recurrence in patients with recurrent depression who were treated with prolonged maintenance therapy. 1H-MRS parameters were analyzed in 48 patients with recurrent depression who required maintenance therapy with antidepressant medication prescribed by a psychiatrist and who continued with the same antidepressant during the maintenance phase, either to recurrence of depression, completion of the 10-year observation period, or the start of the withdrawal phase (tapering-off antidepressant). N-acetylaspartate (NAA), choline-containing metabolites (Cho), creatine (Cr), and glutamine/glutamate were measured at the start of the recovery phase and 6 months later. Recurrent depressive episodes occurred in 20 patients. These individuals had a smaller increase in Cho/Cr after the beginning of the recovery phase compared to the non-recurrent patient group and also exhibited a decreased NAA/Cr ratio. Sustainable NAA and increased Cho levels at the onset of the recovery phase of the index episode are early markers of antidepressant effectiveness associated with a lower risk of major depressive disorder recurrence. The NAA and Cho changes in the non-recurrent group may be attributable to increased brain resilience, contrary to the transient temporal effect observed in subjects who experienced a depressive episode.

Unexpected toxicity of combined modality therapy for small cell carcinoma of the lung. A Southwest oncology group study

Combination chemotherapy with cyclophosphamide, vincristine, methotrexate and Adriamycin was delivered to 35 patients with small-cell carcinoma of the lung (28 with extensive and 7 with limited disease), including elective administration of intrathecal methotrexate. Whole-brain irradiation (3000 rad in 10 fractions) was then administered, with concomitant systemic cyclophosphamide and methotrexate for patients with extensive disease. Those with limited disease received concomitant chest irradiation without chemotherapy. Maintenance therapy then involved cyclophosphamide 750 mg/m/sup 2/ day 1, and methotrexate 30 mg/m/sup 2/ days 1 and 8, every 3 weeks. In only 2 patients reinduction was carried out at 24 weeks with the originalmore » chemotherapy. Myelosuppression was severe; there were at least 2 drug-related deaths from this cause in the induction period, and 15 febrile episodes with leukopenia. Stomatitis was more frequent and more severe in ''maintenance'' than in ''induction'' courses, especially the first maintenance course which was given with concomitant whole-brain irradiation. In addition, 13 episodes of unusual toxicity occurred in close temporal relation to systemic methotrexate administration, usually associated with stomatitis, in patients who were on maintenance therapy. These included 3 episodes of loss of consciousness, 4 of generalized erythroderma, 2 of ''flu''-like syndrome, and 1 each of the following: fatal, bilateral interstitial pneumonia; reversible, eosinophilic pleural effusion; acute myocardial infarction; and renal compromise with hematuria. As a result of this unexpected and protean toxicity, the pilot study was discontinued. However, at this time seven patients (4 with extensive and 3 with limited disease) remain in complete remission.« less

Music therapy has been applied in hemodialysis (HD) patients for relieving mental stress. Whether the stress-relieving effect by music therapy is predictive of clinical outcome in HD patients is still unclear. We recruited a convenience sample of 99 patients on maintenance HD and randomly assigned them to the experimental (n=49) or control (n=50) group. The experimental group received relaxing music therapy for 1 week, whereas the control group received no music therapy. In the experimental group, we compared cardiovascular mortality in the patients with and without cortisol changes. The salivary cortisol level was lowered after 1 week of music therapy in the experimental group (-2.41±3.08 vs 1.66±2.11 pg/mL, P <0.05), as well as the frequency of the adverse reaction score (-3.35±5.76 vs -0.81±4.59, P <0.05), the severity of adverse reactions score (-1.93±2.73 vs 0.33±2.71, P <0.05), and hemodialysis stressor scale (HSS) score (-6.00±4.68 vs -0.877±7.08, P <0.05). The difference in salivary cortisol correlated positively with HD stress score scales ( r =0.231, P <0.05), systolic blood pressure ( r =0.264, P <0.05), and respiratory rates ( r =0.369, P <0.05) and negatively with finger temperature ( r =-0.235, P <0.05) in the total study population. The 5-year cardiovascular survival in the experimental group was higher in patients whose salivary cortisol lowered by <0.6 pg/mL than that in patients whose salivary cortisol lowered by >0.6 pg/mL (83.8% vs 63.6%, P <0.05). Providing music during HD is an effective complementary therapy to relieve the frequency and severity of adverse reactions, as well as to lower salivary cortisol levels. Differences in salivary cortisol after music therapy may predict cardiovascular mortality in patients under maintenance HD.

Erectile dysfunction (ED) is a problem commonly encountered by patients on methadone maintenance therapy (MMT). This study aimed to assess the prevalence of ED among this group of patients along with its risk factors and association with quality of life (QOL). Male patients on MMT in a tertiary hospital in Malaysia were included in the study. A total of 134 patients with sexual partners were assessed for ED using the International Index of Erectile Function. Patients were assessed for substance use using Opiate Treatment Index (OTI) and depression using the Malay version of the self-rated Montgomery-Asberg Depression Rating Scale (MADRS-BM). QOL was evaluated using World Health Organisation Quality of Life (WHOQOL)-BREF. The prevalence of ED among patients on MMT was 67%, with 26.1% having mild ED, 30.4% having mild-to-moderate ED, 7.0% having moderate ED, and 17.2% having severe ED. Patients with depression were 4 times more likely to have ED compared with patients without depression, whereas increasing age significantly correlated with the severity of ED. Having ED predicted a poorer QOL in the social relationships domain. Depression is highly associated with ED, which negatively influences the social aspect of QOL among patients on methadone maintenance therapy.

Regular physical activity (PA) benefits patients with rheumatoid arthritis (RA), particularly when maintained over time. Research in this area has largely focused on factors associated with initiating PA, while factors contributing to PA maintenance, particularly after lifestyle interventions, have received less attention. This study examined whether higher levels of autonomous motivation, self-efficacy for PA, and greater use of self-regulation skills mediated PA initiation and maintenance 6 months after a theory-based motivational interviewing and self-regulation coaching intervention. Seventy-eight individuals with RA were randomized to receive either a patient-education session (control group), or the patient-education session plus 1 motivational interview and 2 self-regulation coaching sessions (treatment group). Mediation analyses examined the effects of this intervention on PA initiation and maintenance through the intermediate variables autonomous motivation, self-efficacy for PA, and use of self-regulation skills. Analyses were controlled for age, sex, and previous levels of PA. The treatment group reported significantly higher autonomous motivation and greater use of self-regulation skills than controls at posttreatment. Increases in PA from baseline to posttreatment were not mediated by any intermediate variables. However, maintenance of PA from posttreatment to followup (6 months later) was mediated by greater autonomous motivation and use of self-regulation skills. Greater autonomous motivation and use of self-regulation skills predict maintenance of PA following a motivational interviewing and self-regulation coaching intervention. In promoting PA among patients with RA, supporting patient autonomy and teaching self-regulation skills, which focus attention on achieving PA goals, may improve long-term maintenance of PA. © 2016, American College of Rheumatology.

Therapeutic options for patients failing hepatitis C retreatment are limited. EPIC(3) included a prospective trial assessing long-term peginterferon alfa-2b (PegIFNα-2b) maintenance therapy in patients with METAVIR fibrosis scores (MFS) of F2 or F3 who previously failed hepatitis C retreatment. Patients with F2/F3 MFS who failed retreatment were randomized to PegIFNα-2b (0.5 μg/kg/week, n=270) or observation (n=270) for 36 months. Blinded liver biopsies obtained before retreatment and after maintenance therapy were evaluated using MFS and activity scores, and confirmatory testing was performed using FibroTest and ActiTest. In total, 348 patients had paired biopsies: 192 patients had missing post-treatment biopsies and were considered as having no change in fibrosis/activity scores. In total, 16% of patients receiving PegIFNα-2b and 11% of observation patients had improvement in MFS (p=0.32). More PegIFNα-2b than observation patients had improvement in activity score (20% vs. 9%; p <0.001). Among patients treated for >2.5 years, improvement in MFS or activity score was more common with PegIFNα-2b than observation (21% vs. 14%, p=0.08 and 26% vs. 10%, p <0.001). FibroTest and ActiTest evaluations indicated significant benefit associated with PegIFNα-2b in terms of reduced fibrosis progression and improved activity score. The safety profile of PegIFNα-2b was similar to previous studies. PegIFNα-2b did not significantly improve MFS estimated by biopsy compared with observation; however, activity scores were significantly improved and MFS trended toward increased improvement with treatment durations >2.5 years. Both FibroTest and ActiTest were significantly improved during maintenance therapy. Copyright © 2012 European Association for the Study of the Liver. Published by Elsevier B.V. All rights reserved.

Little is known about attitudes toward and experiences with opioid maintenance therapy (OMT) among people who inject drugs in Malaysia, a country where people who inject drugs comprise 1.3% of the adult population. In 2010, 460 people who inject drugs in Greater Kuala Lumpur, Malaysia were surveyed to evaluate attitudes toward and experiences with OMT and treatment readiness. Attitudes towards OMT with both methadone and buprenorphine were assessed using an opinions scale. Multivariable linear regression was used to assess correlates of treatment readiness, measured with the 19-item Stages of Change Readiness and Treatment Eagerness Scale (SOCRATES). All 460 participants used opioids and nearly all (99.1%) met criteria for opioid dependence. Few had had previous experience with methadone (9.3%) or buprenorphine (12.6%) maintenance therapy, yet many had used methadone (55.2%) or buprenorphine (51.7%) outside of treatment settings. Fifteen percent had injected buprenorphine in the past month, and of the few that were currently receiving buprenorphine maintenance therapy, almost all were injecting it. The majority of subjects exhibited a moderate level of treatment readiness and a preference for methadone over buprenorphine. Those with low treatment readiness scores were more likely to have previous experience with compulsory drug detention centers (p<0.01), needle/syringe exchange programs (p<0.005), or be of Indian ethnicity (p<0.001). Past use of methadone (p<0.01), older age (p<0.001), higher stress symptom severity (p<0.001), and sharing of needles or syringes (p<0.05) were associated with higher treatment readiness scores. There are suboptimal levels of OMT experience among people who inject drugs that may be improved by addressing factors that influence patient attitudes. Those individuals with moderate treatment readiness may be targeted by brief motivational and cognitive interventions in primary care, prisons or OMT clinics aimed at improving entry into and retention in treatment.

The objective of this study was to examine factors that predict antiretroviral therapy (ART) access among eligible, HIV-positive methadone maintenance treatment (MMT) clients. We also tested the hypothesis that sustained MMT participation increases the likelihood of accessing ART. A nation-wide cohort study conducted from 1 March 2004 to 31 December 2011. MMT clients were followed from the time of their enrolment in China's national MMT programme until their death or the study end date. Our cohort comprised 7111 ART-eligible, HIV-positive MMT clients, 49.2% of whom remained ART-naive and 50.8% of whom received ART. Demographic variables, drug use history, MMT programme participation and HIV-related clinical characteristics of study participants who remained naive to ART and those who accessed ART were compared by univariate and multivariable analysis. Predictors of accessing ART among this cohort included being retained in MMT at the time of first meeting ART eligibility [adjusted odds ratio (AOR)=1.84, confidence interval (CI)=1.54-2.21, P<0.001] compared to meeting ART eligibility before entering MMT (AOR=0.98, CI=0.80-1.21, P=0.849) or previously entering MMT and dropping out before meeting ART eligibility. Additional predictors were CD4≤200 cells/μl when ART-eligibility requirement was first met (AOR=1.81, CI=1.61-2.05, P<0.001 compared to CD4=201-350 cells/μl), and being in a stable partner relationship (married/cohabitating: AOR=1.14, CI=1.01-1.28, P=0.030). Retained participation in methadone maintenance treatment increases the likelihood that eligible clients will access antiretroviral therapy. These results highlight the potential benefit of colocalization of methadone maintenance treatment and antiretroviral therapy services in a 'one-stop-shop' model. © 2014 Society for the Study of Addiction.

We investigated efficacy and toxicity of replacing conventional triple (cytarabine, methotrexate, and hydrocortisone) intrathecal therapy (TIT) with liposomal cytarabine during maintenance therapy among 40 acute lymphoblastic leukemia patients. Twenty-eight of 29 patients in the TIT arm received TIT and 9/11 in the liposomal cytarabine arm received liposomal cytarabine. Arachnoiditis occurred in all initial 5 patients given liposomal cytarabine and intrathecal prednisolone succinate. Subsequently liposomal cytarabine was given with systemic dexamethasone. Neurotoxicity occurred at 6/27 liposomal cytarabine administrations with concomitant dexamethasone (22%). More liposomal cytarabine-treated patients experienced neurotoxicity in relation to intrathecal therapy during at least 1 cycle compared with TIT-treated patients (6/9 [67%] vs. 3/28 [11%], P=0.002). Apart from intermittent lower extremity sensory pain in 1 liposomal cytarabine-treated patient, no permanent adverse neurological sequelae were observed. In intention-to-treat analysis, projected 5-year event-free survival (pEFS-5y) was borderline higher for patients in the liposomal cytarabine arm compared with the TIT arm (1.0 vs. 0.69, P=0.046). However, pEFS-5y and projected 5-year relapse-free survival did not differ signficantly between patients treated with liposomal cytarabine or TIT (1.0 vs. 0.73, P=0.10; 1.0 vs. 0.76, P=0.12). Larger prospective trials are needed to explore whether liposomal cytarabine should be used as first-line prevention of relapse.
