    2016-02-01

    Status epilepticus (SE) is one of the most frequent neurologic emergencies, and a rapid and effective treatment is warranted. Current guidelines recommend a stepwise approach using a sequence of different antiepileptic drugs with benzodiazepines (BZD) being the first treatment proposed. To provide the more effective treatment as soon as possible, some authors have suggested using a combined polytherapy as first-line treatment. Strong evidence supports the use of benzodiazepines, mostly lorazepam and midazolam as initial monotherapy treatment for SE. Insufficient data are available to support the use of nonsedating antiepileptic drugs as phenytoin, valproic acid, or levetiracetam without a previous benzodiazepine administration. Studies assessing the role of a combined initial therapy are rare, if not missing. Moreover, owing the wide range of SE etiologies, a "one fits all" initial polytherapy seems difficult to achieve. After reviewing the available evidence, guidelines, and current practices regarding monotherapy and polytherapy as first-line treatment in SE in adults, the authors propose a rational algorithm for early antiseizure treatment in SE.

    The goals of treatment for metastatic breast cancer (MBC) are to prolong overall survival (OS) while maximizing quality of life, palliating symptoms, and delaying tumor progression. For many years, anthracyclines and taxanes have been the mainstay of treatment for MBC, but these agents are now commonly administered earlier in the course of the disease. A recent meta-analysis revealed adverse effects on OS and overall response rates in patients with MBC receiving first-line anthracycline-based chemotherapy following relapse on adjuvant chemotherapy. Noncrossresistant cytotoxic agents and combinations that combine high clinical activity and acceptable tolerability while being convenient for patients are therefore needed for the first-line treatment of MBC patients. Capecitabine has substantial antitumor activity in the first-line treatment of patients with MBC in prospective, randomized, phase II/III clinical trials as monotherapy and in combination with biologic and novel agents. First-line capecitabine monotherapy has a favorable safety profile, lacking myelosuppression and alopecia, and does not compromise the administration of further lines of chemotherapy. Capecitabine is suitable for long-term administration without the cumulative toxicity that can limit the prolonged use of other chemotherapy agents. Here, we review the available data on capecitabine as a single agent for first-line treatment of patients with human epidermal growth factor receptor 2–negative MBC. PMID:22418569

    In 2001, caspofungin received market authorisation by the FDA and EMA and is globally licensed for several indications, including candidiasis, empirical antifungal therapy in patients with neutropenic fever of unknown origin and treatment of invasive aspergillosis in patients refractory to or intolerant of amphotericin B, lipid formulations of amphotericin B or itraconazole. Despite the lack of phase III data in first-line treatment of invasive aspergillosis, increasing evidence supports the use of first-line therapy. Here, we analyse the evidence of therapeutic activity, represented by favourable response rates, of caspofungin for invasive aspergillosis. A systematic literature search was conducted to identify international presentations and papers reporting monotherapy with caspofungin. Efficacy data are summarised separately for first-line and salvage therapy. Thirty-one papers and published abstracts reported caspofungin therapy for aspergillosis. Fifteen full papers and two abstracts fulfilled the criteria of reporting significant outcome data for caspofungin monotherapy for invasive aspergillosis. Consistent with other analyses and the known safety profile, few adverse events and associated terminations of caspofungin medication have been reported. Although a randomised, comparative, prospective study using caspofungin in this indication is still lacking, growing evidence supports the efficacy of this echinocandin not only for salvage but also for first-line therapy.

    2016-01-01

    Introduction Idiopathic Generalized Tonic-Clonic Seizures (GTCS) are frequently encountered in adults. Their successful control is necessary to improve the quality of life of these patients. Valproic acid is a simple branched-chain carboxylic acid and lamotrigine is a phenyltriazine derivative. Opinions differ in regards to their effectiveness in idiopathic GTCS. Aim To compare the effectiveness of valproic acid and lamotrigine in newly diagnosed adults with idiopathic generalized tonic-clonic seizures. Materials and Methods The present prospective randomized study was conducted on 60 patients suffering from idiopathic GTCS. Thirty patients received valproic acid and rest 30 patients received lamotrigine. All patients were followed regularly monthly for one year for treatment response and adverse effects. Results After 12 months follow-up, 76.67% patients taking valproic acid and 56.67% patients taking lamotrigine were seizure-free. Common adverse effects recorded were nausea, dyspepsia, headache and skin rash. Conclusion Valproic acid is more effective than lamotrigine as first-line drug in the treatment of adults with newly diagnosed idiopathic generalized tonic-clonic seizures.

    2014-01-01

    Background The purpose of this study was to explore the budget impact of dutasteride plus tamsulosin fixed-dose combination (DUT + TAM FDC) versus tamsulosin monotherapy, in the treatment of patients with benign prostatic hyperplasia (BPH) from the perspective of the Greek healthcare insurance system. Methods A Microsoft Excel-based model was developed to estimate the financial consequences of adopting DUT + TAM FDC within the Greek healthcare setting. The model, compared six mutually exclusive health states in two alternative treatment options: current standard of care and the introduction of DUT + TAM FDC in the market. The model used clinical inputs from the CombAT study; data on resource use associated with the management of BPH in Greece were derived from expert panel, and unit cost data were derived from official reimbursement tariffs. A payer perspective was taken into account. As patient distribution data between public and private sectors are not available in Greece two scenarios were investigated, considering the whole eligible population in each scenario. A 4 year time horizon was taken into account and included treatment costs, number of transurethral resections of the prostate (TURPs) and acute urinary retention (AUR) episodes avoided. Results The clinical benefit from the market adoption of DUT + TAM FDC in Greece was 1,758 TURPs and 972 episodes of AUR avoided cumulatively in a four year period. The increase in total costs from the gradual introduction of DUT + TAM FDC to the Greek healthcare system ranges from €1.3 million in the first year to €5.8 million in the fourth year, for the public sector, and €1.2 million to €4.0 million, for the private sector. This represents an increase of 1.91% to 7.94% for the public sector and 1.10% 3.29% in the private sector, during the 4-year time horizon. Conclusions Budget impact analysis (BIA) results indicated that the gradual introduction of DUT + TAM FDC, would increase the overall

    Ocular Surface Disease (OSD) is prevalent among medically treated patients with glaucoma. This is basically related to three key-points: OSD and glaucoma are both prevalent in elderly and are common comorbidities in the same patient; the role of the active ingredient of the medical antiglaucomatous therapy; the role of the preservative agent of this medical therapy. Considering the actual state of literature we can state that the active glaucoma agent have a role in OSD, but the main cause seems to be the preservative agent, in particular referring to benzalkonium chloride, BAK. In the clinical evaluation of dry eye patients there is no actually established gold standard. Since the ocular surface injury not only causes dry eye, red eye, eye itching, photophobia and other discomforts, but also increases the risk of failure of glaucoma surgery in patients, it becomes fundamental a complete and good clinical evaluation of OSD (considering Schirmer’s test, tear breakup time, corneal and conjunctival staining) together with a good evaluation of patients’ quality of life (with validated questionnaires). Development of complex preparations, preservative-free and/or novel preservative preparations for glaucoma therapy could provide a promising approach in the prevention of ocular surface injuries.

    OBJECTIVE To describe patient profiles and clinical outcomes associated with first-line endocrine monotherapy (ET) and chemotherapy (CT) for postmenopausal HR+/HER2− metastatic breast cancer (mBC) patients. METHODS This is a retrospective chart review of 139 postmenopausal HR+/HER2− mBC patients initiating first-line ET monotherapy or CT. Overall survival (OS) was described using Kaplan–Meier curves. Exploratory comparative proportional hazards regression was conducted. RESULTS Patients on first-line CT had significantly more frequent liver metastases than patients on first-line ET monotherapy at baseline. The median OS was 35.5 months [95% confidence interval (CI), 22.7–41.2 months] for patients on first-line ET monotherapy and 22.2 months (95% CI, 13.6–25.9 months) for those on first-line CT (P = 0.021). Adjusting for baseline characteristics, the OS between first-line ET monotherapy and CT was not significantly different. CONCLUSIONS Patients who were prescribed CT as first-line treatment had evidence of more advanced disease at baseline and shorter OS than those who received ET monotherapy as first-line treatment, suggesting a need for additional safe and effective treatment options for these patients.

    Human inspection of security features is based on a cycle of actions: the development and execution of a strategy, and the observation and evaluation of results. These actions aim at establishing the state of the object: genuine or fake. These actions require knowledge, which is either in the head (memorized) or in the world (provided by the object). It is argued that knowledge in the world is most suitable for adequate inspection of first line security features. In contrast, knowledge in the head cannot be relied on, unless standardization is consistently implemented. From the action cycle five pertinent questions ensue. How easily can the user: (1) determine and understand the function of the device? (2) tell what actions are possible? (3) execute the actions? (4) observe the results? (5) compare the observed results with the expected results? A set of generic design rules is derived, involving the function of the device, the execution of a strategy, and the evaluation of the result. A number of first line security features is evaluated from this human factors point of view. These comprise substrate embedded features (watermark, windowed thread), features added to the ink (iridescent pigment), printed features (intaglio, small lettering, see-throughs, latent images), and post-printed features (iridescent foils). It is concluded that many current security features do not meet basic ergonomic design rules. However, iridescent optically variable devices tend to have a potential to meet these requirements.

    The science of antibiotic therapy for infectious diseases continues to evolve. In many instances where empiric coverage is necessary, treatment with more than one agent is considered prudent. If an etiology is identified, antibiotics are modified based on culture and susceptibility data. Even when the organism is known, more than one antibiotic may be needed. Decisions about antibiotics should be made after assessments of pertinent clinical information, laboratory and microbiology information, ease of administration, patient compliance, potential adverse effects, cost, and available evidence supporting various treatment options. Clinicians also need to consider synergy and local resistance patterns in selecting therapeutic options. In this article, the authors outline monotherapy and combination therapy options for several common infectious diseases. PMID:17116443

    The antihypertensive efficacy and acceptability of perindopril (P) were compared to those of captopril (C), atenolol (A) and a diuretic, hydrochlorothiazide + amiloride (D), in 3 double-blind parallel multicenter studies involving 165, 173, and 165 patients, respectively. Patients with essential hypertension and a supine DBP between 95 and 125 mmHg (mean 103.9, 106.2, and 105.2 mmHg, respectively) after a 1-month placebo period were randomized to P 4 mg once daily (o.d.) and either C 25 mg twice daily, or A 50 mg o.d. or D (hydrochlorothiazide 50 mg + amiloride 5 mg o.d.) and treated for 3 months, with visits at monthly intervals. If necessary, treatment was adjusted at each visit to control BP (supine DBP less than or equal to 90 mm Hg): firstly by doubling the dose and secondly, one month later, by the addition of a second drug, a diuretic in the studies versus C or A, a beta-blocker in the study versus D. At 3 months, BP control on monotherapy in the three studies was achieved in the following proportion of patients: 49% with P vs 49% with C; 55% with P vs 48% with A; 72% with P vs 72% with D. Most of the patients controlled by P received 4 mg, about 15% were controlled with 8 mg. A further percentage of patients was controlled with combination therapy, the combination with a diuretic being more effective with P than with C (26 vs 8%) or A (23 vs 10%) and the combination with a beta-blocker being less effective with P than with D (5 vs 13%). The total percentage of patients controlled was greater with P than with C (75 vs 57%, p = 0.016) or A (78 vs 58%, p = 0.006) and there was no significant difference between P and D (78 vs 84%). The drop-out rate due to side-effects was up to 6% with P, similar to that observed with C (4%), A (5%) and D (5%). Most of the complaints reported with P were minor and non-specific, their incidence being similar to that observed with the other drugs. Cough was reported with both P (1%) and C (2%) as well as with A (1%) and D (1

    The Clinical Assessment Program and Teflaro(®) Utilization Registry (CAPTURE) is a multicenter registry study of acute bacterial skin and skin structure infection (ABSSSI) and community-acquired bacterial pneumonia (CABP) patients treated with ceftaroline fosamil in the US. Data for this analysis were collected between August 2011 and February 2013 at US study centres by randomly ordered chart review. Clinical success rates among ABSSSI patients were >81% when ceftaroline fosamil was used as first- or second-line therapy, including monotherapy and concurrent therapy. Among CABP patients, clinical success rates were >77% among first-line and second-line patients and patients who received first-line concurrent therapy or second line monotherapy or concurrent therapy. For CABP patients treated with ceftaroline fosamil as first-line monotherapy, the clinical success rate was 70%. Ceftaroline fosamil is an effective treatment option for patients with ABSSSI or CABP with similar clinical success rates when used as first-line or second-line treatment. PMID:25817579

    This article examines evidence-based findings in the literature on the efficacy of perindopril 2 mg/indapamide 0.625 mg, a first-line, low-dose antihypertensive drug combination. In regulatory Phase II and III trials, perindopril/indapamide significantly lowered blood pressure compared with other first-line therapies (atenolol, losartan and irbesartan). This was also the case in STRAtegies of Treatment in Hypertension: Evaluation, a postregistration study versus current monotherapies and stepped-care therapy with different classes of antihypertensive agents. The efficacy/safety ratio (both clinical and with regard to laboratory parameters) of perindopril/indapamide was good. Perindopril/indapamide provides additional antihypertensive efficacy compared with each component used alone and with current monotherapies, with major efficacy on systolic blood pressure, an important predictor of cardiovascular risk. It also reduces pulse pressure, an independent cardiovascular risk factor, large-vessel arterial stiffness and microcirculatory alterations. The fixed dosage of a once-daily tablet, ensures optimal ease of use and enhances patient compliance. Perindopril/indapamide also reduces target organ damage in patients at high cardiovascular risk, such as patients with cardiac hypertrophy and Type 2 diabetics with albuminuria. These benefits, together with the good efficacy/tolerability ratio, fulfill the requirements of the European Society of Hypertension and of the Seventh Report of the Joint National Committee on Prevention, Detection, Evaluation, and Treatment of High Blood Pressure guidelines for low-dose, first-line combination therapy in hypertension.

    The development of antiretroviral therapy (ART) with current triple drug combinations has dramatically reduced morbidity and mortality in HIV-infected patients. However, there is a need for less toxic treatments without sacrificing efficacy, as well as for less expensive drugs to facilitate universal access to this therapy. The protease inhibitors (PI) administered with ritonavir have a favorable pharmacokinetic profile and high genetic barrier and consequently are ideal candidates for use in monotherapy, thus avoiding the toxicity and cost associated with nucleoside analogs, as well as preserving drugs for future options. The promising results of studies performed with lopinavir/ritonavir (LPV/r) in induction-maintenance regimens in patients without prior failure to PIs encourage research into the cost-effectiveness of LPV/r in monotherapy from the beginning of ART. The few studies performed in this context seem to indicate the following: a) LPV/r monotherapy achieves undetectable viral loads in a large proportion of treatment-naïve patients, b) future treatment options are not compromised in patients not achieving undetectable viral loads since the likelihood of resistance mutations is low and treatment intensification achieves suppression of viral replication, and c) strategies for early detection can probably be considered in patients who will not achieve complete suppression with LPV/r monotherapy. Nevertheless, before LPV/r monotherapy can be considered a first-line option, new studies with larger samples and longer follow-up are required. These studies should pay particular attention to viral replication in areas where PI show less penetration. PMID:19572437

    Background. The development of drug resistance to nucleoside reverse transcriptase inhibitors (NRTIs) and nonnucleoside reverse transcriptase inhibitors (NNRTIs) has been associated with baseline human immunodeficiency virus (HIV)-1 RNA level (VL), CD4 cell counts (CD4), subtype, and treatment failure duration. This study describes drug resistance and levels of susceptibility after first-line virologic failure in individuals from Thailand, South Africa, India, Malawi, Tanzania. Methods. CD4 and VL were captured at AIDs Clinical Trial Group (ACTG) A5230 study entry, a study of lopinavir/ritonavir (LPV/r) monotherapy after first-line virologic failure on an NNRTI regimen. HIV drug-resistance mutation associations with subtype, site, study entry VL, and CD4 were evaluated using Fisher exact and Kruskall–Wallis tests. Results. Of the 207 individuals who were screened for A5230, sequence data were available for 148 individuals. Subtypes observed: subtype C (n = 97, 66%) AE (n = 27, 18%), A1 (n = 12, 8%), and D (n = 10, 7%). Of the 148 individuals, 93% (n = 138) and 96% (n = 142) had at least 1 reverse transcriptase (RT) mutation associated with NRTI and NNRTI resistance, respectively. The number of NRTI mutations was significantly associated with a higher study screening VL and lower study screening CD4 (P < .001). Differences in drug-resistance patterns in both NRTI and NNRTI were observed by site. Conclusions. The degree of NNRTI and NRTI resistance after first-line virologic failure was associated with higher VL at study entry. Thirty-two percent of individuals remained fully susceptible to etravirine and rilpivirine, protease inhibitor resistance was rare. Some level of susceptibility to NRTI remained; however, VL monitoring and earlier virologic failure detection may result in lower NRTI resistance. PMID:24795328

    Objective: To assess the efficacy and safety of eslicarbazepine acetate (ESL) monotherapy. Methods: This post hoc pooled analysis of 2 randomized double-blind studies (093-045 and -046) included adults with partial-onset seizures medically uncontrolled by 1 or 2 antiepileptic drugs (AEDs). Following the baseline period (8 weeks), eligible patients were randomized 2:1 to receive ESL 1,600 mg or 1,200 mg once daily for 18 weeks; the primary endpoint was study exit by meeting predefined exit criteria (signifying worsening seizure control). In each study, treatment was considered effective if the upper 95% confidence limit for exit rate was lower than the historical control threshold (65.3%). Results: Pooled exit rates were as follows: ESL 1,600 mg = 20.6% (95% confidence interval: 15.6%–26.8%); ESL 1,200 mg = 30.8% (23.0%–40.5%). Use of 2 baseline AEDs or rescue medication, US location, epilepsy duration ≥20 years, and higher maximum baseline seizure frequency were associated with higher exit risks. Median percent reductions in standardized seizure frequency between baseline and the 18-week double-blind period were as follows: ESL 1,600 mg = 43.2%; ESL 1,200 mg = 35.7%; baseline carbamazepine use was associated with smaller reductions. Safety profiles were similar between ESL doses. Conclusions: Exit rates for ESL monotherapy (1,600 mg and 1,200 mg once daily) were lower than the historical control threshold, irrespective of baseline AED use and region, with no additional safety concerns identified. Clinical factors and location clearly influence treatment responses in conversion-to-monotherapy trials. Classification of evidence: This pooled analysis provides Class IV evidence that for adults with medically uncontrolled partial-onset seizures, ESL monotherapy is well tolerated and effective.

    Abstract Background: Brain metastases (BMs) are a common and serious complication of non-small cell lung cancer (NSCLC). Whole-brain radiotherapy (WBRT), surgery, and molecular targeted therapy are usually used to treat NSCLC with BM. Chemotherapeutic options for BM are limited by tumor resistance, ineffective agents, and the blood–brain barrier. Pemetrexed/cisplatin is the preferred chemotherapy in nonsquamous NSCLC, but the efficacy of this treatment for nonsquamous NSCLC with BM is uncertain. Methods: We present a case of nonsquamous NSCLC with asymptomatic BM presenting with irritating cough and right shoulder back pain (unknown sensitizing epidermal growth factor receptor mutations or anaplastic lymphoma kinase). Results: He benefited from administration of first-line chemotherapy of pemetrexed/cisplatin. Partial remission was achieved in the primary lesion of the lungs and BM lesion. He was further given 3 cycles of pemetrexed monotherapy and WBRT. Complete remission was further achieved in BM lesion. Conclusion: The findings of clinical trials and theoretical studies about the current pemetrexed/cisplatin in the treatment of nonsquamous NSCLC with BM are also summarized to provide a reference for the application of pemetrexed/cisplatin in nonsquamous NSCLC with BM. Whether or not pemetrexed/cisplatin is definitely effective in nonsquamous NSCLC with BM must be proven by subsequent phase III clinical trials. PMID:27512852

    Span of control, the number of people reporting to a manager, is an important management concept. It determines the structure of an organization and has financial, human resource, and quality of care implications. In nursing, the first line manager fills one of the most critical roles in the administration of nursing services. For this manager to perform her responsibilities effectively, an optimal span of control is necessary. Span of control is influenced by a number of factors. By understanding these factors, we can influence them to optimize the span of control of the nurse manager. PMID:3367230

    Background Glucocorticoids are the cornerstone treatment of polymyalgia rheumatica (PMR) but induce adverse events. Objectives To evaluate the efficacy and safety of first-line tocilizumab in PMR. Methods In a prospective open-label study (ClinicalTrials.gov: NCT01713842), 20 glucocorticoid-free patients fulfilling Chuang's PMR criteria, with symptom onset within the last 12 months and a PMR activity score (PMR-AS) >10, each received three tocilizumab infusions at 4-week intervals, without glucocorticoids, followed by oral prednisone from weeks 12 to 24 (0.15 mg/kg if PMR-AS ≤10 and 0.30 mg/kg otherwise). The primary end point was the proportion of patients with PMR-AS≤10 at week 12. Results Baseline median PMR-AS was 36.6 (IQR 30.4–43.8). At week 12, all patients had PMR-AS≤10 and received the low prednisone dosage. Median PMR-AS at weeks 12 and 24 was 4.5 (3.2–6.8) and 0.95 (IQR 0.4–2), respectively (p<0.001 vs baseline for both time points). No patient required rescue treatment. Positron emission tomography-CT showed significant improvements. The most common adverse events were transient neutropenia (n=3) and leucopenia (n=5); in one patient, the second tocilizumab infusion was omitted due to leucopenia. Conclusions Tocilizumab monotherapy is effective in recent-onset PMR. Randomised controlled trials are warranted. Trial registration number NCT01713842. PMID:26929219

  2. Very-low-dose combination: a first-line choice for the treatment of hypertension?

    PubMed

    Waeber, Bernard

    2003-06-01

    Essential hypertension is a very heterogeneous disease and different pressor mechanisms might interact to increase blood pressure. It is therefore not surprising that antihypertensive drugs given as monotherapies normalize blood pressure in only a proportion of hypertensive patients. This is, for instance, the case for diuretics, angiotensin-converting enzyme (ACE) inhibitors and angiotensin II type 1 (AT1) receptor antagonists administered as single agents. The rationale for combining antihypertensive agents relates in part to the concept that the blood pressure-decreasing effect may be enhanced when two classes are coadministered. Also, combination treatment serves to counteract the counter-regulatory mechanisms that are triggered whenever pharmacologic intervention is initiated and act to limit the efficacy of the antihypertensive medication. For example, the compensatory increase in renin secretion induced by sodium depletion may become the predominant factor sustaining high blood pressure. Simultaneous blockade of the renin-angiotensin system, with either an ACE inhibitor or an AT1 receptor blocker, makes this compensatory hyper-reninaemia ineffective and allows maximum benefit from sodium depletion. The increased effectiveness obtained by combining a blocker of the renin-angiotensin system with a low dose of a diuretic is not obtained at the expense of reduced tolerability compared with the individual components administered alone. Fixed very-low-dose combinations containing an ACE inhibitor or an AT1 receptor blocker and a diuretic are therefore likely to become increasingly used, not only as second-line therapy, but also as first-line treatment. This is the case, for instance, for the fixed very-low-dose combination of the ACE inhibitor perindopril (2 mg) and the diuretic indapamide (0.625 mg), as this preparation is very effective in decreasing blood pressure while maintaining a tolerability that is similar to that of placebo.

    Background and objective Several clinical trials have proven that icotinib hydrochloride, a novel epidermal growth factor receptor (EGFR)–tyrosine kinase inhibitor, exhibits encouraging efficacy and tolerability in patients with advanced non-small-cell lung cancer (NSCLC) who failed previous chemotherapy. This study was performed to assess the efficacy and toxicity of icotinib as first-line therapy for patients with advanced pulmonary adenocarcinoma with EGFR-sensitive mutation. Patients and methods Thirty-five patients with advanced NSCLC with EGFR-sensitive mutation who were sequentially admitted to the First Affiliated Hospital of Xi’an Jiaotong University from March 2012 to March 2014 were enrolled into our retrospective research. All patients were administered icotinib as first-line treatment. The tumor responses were evaluated using Response Evaluation Criteria in Solid Tumors (RECIST, version 1.1). Results Among the 35 patients, the tumor objective response rate (ORR) and disease control rate were 62.9% (22/35) and 88.6% (31/35), respectively. The median progression-free survival was 11.0 months (95% confidence interval [CI]: 10.2–11.8 months), and median overall survival was 21.0 months (95% CI: 20.1–21.9 months). The most common drug-related toxicities were rashes (eleven patients) and diarrhea (nine patients), but these were generally manageable and reversible. Conclusion Icotinib monotherapy is effective and tolerable as first-line treatment for patients with advanced lung adenocarcinoma with EGFR-sensitive mutation. PMID:26966381

    Oseltamivir (has known by its brand name 'Tamiflu') is a prodrug, requiring ester hydrolysis for conversion to the active form, Oseltamivir carboxylate. Oseltamivir was the first orally active neuraminidase inhibitor commercially developed by US based Gilead Sciences and is currently marketed by F. Hoffmann-La Roche (Roche). Oseltamivir is an antiviral drug which works by blocking the function of the viral neuraminidase protein. US FDA approved Oseltamivir for prophylaxis of uncomplicated influenza A and B. Currently, Oseltamivir is the only first line defense drug available for the treatment of Swine Flu. Orally Oseltamivir is well tolerated and effective in treatment of influenza in adolescents and adults, including the elderly and patients with chronic cardiac and/or respiratory disease. Many of the pharmaceutical companies targeted Oseltamivir as a block buster molecule. In present review, we have tried to cover chemistry, mode of binding, total synthesis, current patent status, adverse effect and clinical status of Oseltamivir giving emphasis on medicinal chemistry aspect.

    Dasatinib was approved for the treatment of chronic phase (CP) chronic myeloid leukemia (CML) patients in first line therapy based on the demonstration of efficacy and safety reported in patients enrolled in clinical trials. We describe a multicentric Italian "real-life" experience of dasatinib used as frontline treatment outside clinical trials. One hundred and nine patients (median age 54 years) were treated from January 2012 to December 2013. Increased incidence of high risk patients were detected according to stratification (26% according to Sokal score, 19% according to Euro score and 16% according to EUTOS) when compared to company sponsored studies. Median time from diagnosis to start of dasatinib was 18 days. Ten patients received unscheduled starting dose (6 patients 50mg and 4 patients 80 mg QD), whereas 99 patients started with 100mg QD. At 3 months, 92% of patients achieved a BCR-ABL ratio less than 10%. At 6 months, the rate of CCyR was 91% and the rate of MR3 was 40%, with 8% of the patients reaching MR4.5. Ninety-three patients were evaluable at 12 months: the rate of MR3 was 62%, with MR4.5 being achieved by 19% of the patients. At a median follow-up of 12 months, 27 patients (24.7%) were receiving the drug at reduced dose. Two patients (1.8%) experienced a lymphoid blast crisis and the overall incidence of resistance was 8%. As regards safety, the major side effects recorded were thrombocytopenia, neutropenia and pleural effusions, which occurred in 22%, 10% and 8% of patients, respectively. Present results, achieved in a large cohort of patients treated outside clinical trials, further confirm the efficacy and safety of dasatinib as firstline treatment in CML. PMID:26643920

    Objective. Patients with gastroenteropancreatic neuroendocrine carcinoma (NEC) have a poor prognosis. Platinum-based combination chemotherapy is commonly used as first-line treatment; however, the role of salvage chemotherapy remains unknown. This study aimed to analyze the efficacy and safety of amrubicin monotherapy in patients with platinum-refractory gastroenteropancreatic NEC. Methods. Among 22 patients with advanced gastroenteropancreatic NEC, 10 received amrubicin monotherapy between September 2007 and May 2014 after failure of platinum-based chemotherapy. The efficacy and toxicity of the treatment were analyzed retrospectively. Results. Eight males and two females (median age, 67 years (range, 52-78)) received platinum-based chemotherapy, including cisplatin plus irinotecan (n = 7, 70%), cisplatin plus etoposide (n = 2, 20%), and carboplatin plus etoposide (n = 1, 10%) before amrubicin therapy. Median progression-free survival and overall survival after amrubicin therapy were 2.6 and 5.0 months, respectively. Two patients had partial response (20% response rate), and their PFS were 6.2 months and 6.3 months, respectively. Furthermore, NEC with response for amrubicin had characteristics with a high Ki-67 index and receipt of prior chemotherapy with cisplatin and irinotecan. Grade 3-4 neutropenia and anemia were observed in four and five patients, respectively. Conclusion. Amrubicin monotherapy appears to be potentially active and well-tolerated for platinum-refractory gastroenteropancreatic NEC. PMID:26199623

    Purpose: To prospectively assess the efficacy and safety of switching to bimatoprost monotherapy or brinzolamide and latanoprost combination therapy in patients who had been receiving latanoprost monotherapy. Methods: A prospective, open-label study was conducted. Patients with primary open-angle glaucoma or ocular hypertension who had been receiving latanoprost monotherapy for three months or more were enrolled. Bimatoprost was substituted for latanoprost in one eye (BIM group), and brinzolamide was added to the latanoprost in the other eye (BRZ group) simultaneously. The patients underwent examinations at 6 weeks (visit 1) and 12 weeks (visit 2) after changing therapies. Subsequently, the treatments were returned to latanoprost monotherapy. The patients underwent another examination 6 weeks (visit 3) after the return to latanoprost. The parameters examined were intraocular pressure (IOP), conjunctival hyperemia, and corneal epithelial damage. Results: Twenty-six patients (13 men and 13 women) completed the protocol. Both groups showed a significant IOP reduction at visits 1 and 2 compared with the baseline, with a similar magnitude (BIM group: P = 0.016 at visit 1, P = 0.025 at visit 2, BRZ group: P = 0.0006 at visit 1, P = 0.028 at visit 2). The IOPs at the baseline and on visit 3 were similar in both groups (P = 0.7). The two groups showed no changes in either conjunctival hyperemia or corneal epithelial damage compared with the baseline. Conclusion: Bimatoprost monotherapy and brinzolamide adjunctive to latanoprost similarly reduced the IOP, with no additive adverse effects, compared with latanoprost monotherapy. PMID:27073587

    In the recent years, a number of targeted therapies have been approved for first-line treatment of patients with metastatic renal cell carcinoma. A systematic review was conducted to assess the clinical efficacy, safety and effect of all first-line treatments evaluated to date on health-related quality of life (HRQoL). A systematic search of Embase, Cochrane and MEDLINE databases was performed to identify randomized controlled trials (1980-2015) evaluating any targeted therapy/immunotherapy against placebo or any other targeted intervention/immunotherapy in treatment-naive patients with metastatic renal cell carcinoma. Conference proceedings from major cancer congresses (2007-2015) were handsearched. Sixteen randomized controlled trials were identified, mostly phase III. Overall, targeted therapies were associated with either improved [sunitinib, bevacizumab+interferon α (IFNα) and temsirolimus] or comparable (sorafenib) progression-free survival (PFS) versus IFNα monotherapy. Sunitinib demonstrated comparable PFS and overall survival to pazopanib, comparable PFS to sorafenib and shorter PFS compared with bevacizumab+IFNα (although no conclusions were made with regard to superiority/inferiority). Compared with sorafenib, tivozanib demonstrated a significantly longer PFS, and both tivozanib and axitinib demonstrated higher response rates. Nintedanib demonstrated comparable PFS and overall survival to sunitinib in a phase II trial. Temsirolimus, sunitinib and sorafenib treatment led to better HRQoL versus IFNα; pazopanib was associated with better HRQoL versus sunitinib. No direct meta-analyses or indirect treatment comparison analysis were undertaken because of noncomparability of the trials. In general, targeted therapies demonstrated favourable clinical efficacy and improved HRQoL compared with IFNα monotherapy. The newer therapies, tivozanib and axitinib (but not nintedanib), appeared to exhibit greater clinical benefit (response rate) than older tyrosine

    A 56-year-old man receiving hemodialysis treatment was hospitalized for examination of a mass in the right middle lobe. Chest computed tomography showed a right hilar mass shadow accompanied by pleural effusion. Non-small cell lung cancer (NSCLC) was diagnosed by cytological examination of the pleural effusion. No epidermal growth factor receptor (EGFR) mutation was found. He was treated with 6 courses of docetaxel as first-line chemotherapy. Docetaxel was administered on the same day as hemodialysis. Adverse events, including hematotoxicity, were managed safely and no delay in administration occurred. This chemotherapy resulted in a partial response. Because docetaxel is metabolized in the liver and does not affect renal function, it can be administered as a standard regimen. This suggests that docetaxel monotherapy is an efficient therapy for non-small cell lung cancer patients receiving hemodialysis. PMID:21066867

    We sought to evaluate the efficacy and safety of capecitabine-based therapy as first-line chemotherapy in advanced breast cancer. Randomised controlled trials of capecitabine monotherapy or combined treatment were included in the meta-analysis. PubMed, EMBASE, the Cochrane Library database and important meeting summaries were searched systematically. Outcomes were progression-free survival (PFS), overall survival (OS), overall response rate (ORR) and grades 3-4 drug-related adverse events.Nine trials with 1798 patients were included. The results indicated a significant improvement with capecitabine-based chemotherapy compared with capecitabine-free chemotherapy in ORR (relative risk [RR] 1.14, 95% confidence interval [CI] 1.03 to 1.26, P = 0.013) and PFS (hazard ratio [HR] 0.77, 95% CI 0.69 to 0.87, P < 0.0001). Overall survival favoured capecitabine-based chemotherapy, but this was not significant. There were more incidences of neutropenia and neutropenic fever in the capecitabine-free chemotherapy group and more vomiting, diarrhoea and hand-foot syndrome in the capecitabine-based chemotherapy group. There were no significant differences in nausea, fatigue, cardiotoxicity or mucositis/stomatitis between the two treatment regimens.Capecitabine-based chemotherapy significantly improves ORR and PFS in patients with advanced breast cancer, but has no demonstrable impact on OS. Capecitabine-based regimens are suitable as first-line treatment for patients with advanced breast cancer. PMID:26420815

    The aim of this study was to investigate first-line nursing home managers’ views on their leadership and related to that, palliative care. Previous research reveals insufficient palliation, and a number of barriers towards implementation of palliative care in nursing homes. Among those barriers are issues related to leadership quality. First-line managers play a pivotal role, as they influence working conditions and quality of care. Nine first-line managers, from different nursing homes in Sweden participated in the study. Semi-structured interviews were conducted and analysed using qualitative descriptive content analysis. In the results, two categories were identified: embracing the role of leader and being a victim of circumstances, illuminating how the first-line managers handle expectations and challenges linked to the leadership role and responsibility for palliative care. The results reveal views corresponding to committed leaders, acting upon demands and expectations, but also to leaders appearing to have resigned from the leadership role, and who express powerlessness with little possibility to influence care. The first line managers reported their own limited knowledge about palliative care to limit their possibilities of taking full leadership responsibility for implementing palliative care principles in their nursing homes. The study stresses that for the provision of high quality palliative care in nursing homes, first-line managers need to be knowledgeable about palliative care, and they need supportive organizations with clear expectations and goals about palliative care. Future action and learning oriented research projects for the implementation of palliative care principles, in which first line managers actively participate, are suggested. PMID:25628769

    Purpose Most patients with chronic lymphocytic leukemia (CLL) are elderly and/or have comorbidities that may make them ineligible for fludarabine-based treatment. For this population, chlorambucil monotherapy is an appropriate therapeutic option; however, response rates with chlorambucil are low, and more effective treatments are needed. This trial was designed to assess how the addition of rituximab to chlorambucil (R-chlorambucil) would affect safety and efficacy in patients with CLL. Patients and Methods Patients with first-line CLL were treated with rituximab (375 mg/m2 on day 1, cycle one, and 500 mg/m2 thereafter) plus chlorambucil (10 mg/m2/d all cycles; day 1 through 7) for six 28-day cycles. For patients not achieving complete response (CR), six additional cycles of chlorambucil alone could be administered. The primary end point of the study was safety. Results A total of 100 patients were treated with R-chlorambucil, with a median follow-up of 30 months. Median age of patients was 70 years (range, 43 to 86 years), with patients having a median of seven comorbidities. Hematologic toxicities accounted for most grade 3/4 adverse events reported, with neutropenia and lymphopenia both occurring in 41% of patients and leukopenia in 23%. Overall response rates were 84%, with CR achieved in 10% of patients. Median progression-free survival was 23.5 months; median overall survival was not reached. Conclusion These results compare favorably with previously published results for chlorambucil monotherapy, suggesting that the addition of rituximab to chlorambucil may improve efficacy with no unexpected adverse events. R-chlorambucil may improve outcome for patients who are ineligible for fludarabine-based treatments. PMID:24638012

    Many disease-modifying therapies are currently available for adults with relapsing-remitting multiple sclerosis (MS) but none of them has been tested in pediatric MS in randomized placebo-controlled trials. At present, as suggested by observational studies and experts' guidelines, interferon-β and glatiramer acetate continue to be the standard first-line treatments for pediatric MS. Observational studies and some controlled unblinded trials have shown a positive effect of these meditations in reducing relapse rate and delaying disease progression, with an acceptable safety profile. The goal of this article is to provide an overview of current knowledge with regard to safety, tolerability, and efficacy of first-line treatment options for MS in the pediatric age group, with the aim of providing guidance for planning first-line treatment of MS in children and adolescents.

    The management of patients with CLL is undergoing significant changes; during the last decade, the outcome of first-line therapies has been markedly improved with the addition of anti-CD20 antibodies to chemotherapy. Today, chemoimmunotherapy for physically fit patients ≤ 65 years should consist of fludarabine, cyclophosphamide, and rituximab (FCR). The combination of bendamustine and rituximab (BR) should be considered in physically fit patients > 65 years and in patients with a higher risk of infections. Patients with reduced fitness and/or relevant comorbidity should receive chlorambucil with a CD20 antibody, preferably obinutuzumab. Regardless of their fitness, patients with CLL carrying genetic aberrations such as del(17p) and/or TP53 mutation poorly respond to chemoimmunotherapy and therefore require different therapeutic approaches. An increasing understanding of the disease biology has led to the development of targeted drugs for the treatment of CLL, such as the BTK inhibitor ibrutinib and PI3K inhibitor idelalisib. These agents have shown efficacy in high-risk and relapsed/refractory patients and are currently being evaluated in clinical trials for first-line therapy. It is anticipated that these compounds and further other novel agents will profoundly change the therapy of CLL. PMID:26332019

    Shirley, Matt; Dhillon, Sohita

    2016-04-01

    Eslicarbazepine acetate (Aptiom(®)) is a once-daily, orally administered antiepileptic drug (AED) approved previously in the EU, USA and several other countries for use as adjunctive therapy for the treatment of partial-onset seizures. Based on the findings of two randomized, dose-blinded, conversion-to-monotherapy phase III trials in patients with uncontrolled partial epilepsy, the US license for eslicarbazepine acetate has recently been expanded to include use as monotherapy for partial-onset seizures. The pivotal trials demonstrated that seizure control following conversion from other AEDs was superior for eslicarbazepine acetate monotherapy (1200 or 1600 mg once daily) compared with a pseudo-placebo historical control. Other efficacy outcomes appeared to support the benefit of treatment, with up to 10 % of patients remaining seizure free and up to 46 % of patients experiencing a ≥50 % reduction from baseline in standardized seizure frequency during the monotherapy periods of the trials. Eslicarbazepine acetate monotherapy was generally well tolerated, with most treatment-emergent adverse events being mild to moderate in severity. Its tolerability profile was generally consistent with the established profile of the drug based on its use as adjunctive therapy. Thus, once-daily eslicarbazepine acetate, either as monotherapy or adjunctive therapy, represents a useful option for the treatment of patients with partial-onset seizures. The recent licensing of the drug in the USA as monotherapy expands the range of treatment options for patients with partial-onset seizures and increases the opportunity to tailor therapy to the individual patient.

  2. Type 2 diabetes and metformin. First choice for monotherapy: weak evidence of efficacy but well-known and acceptable adverse effects.

    PubMed

    2014-11-01

    Many guidelines recommend metformin as first-line therapy for patients with type 2 diabetes. This recommendation is primarily based on the results of the Ukpds trial published in 1998. However, the methodology of this trial has been criticised. In 2014, does the harm-benefit balance of metformin still justify its first-line use in type 2 diabetes? To answer this question, we conducted a review of the literature using the standard Prescrire methodology. In the Ukpds trial, involving about 1700 overweight diabetic patients, metformin monotherapy for about 10 years was more effective in reducing mortality than glycaemic control based mainly on dietary measures, and also more effective than treatment with a sulphonylurea such as chlorpropamide or glibenclamide, or with insulin. However, these results are undermined by several methodological flaws. In the Adopt trial, in which about 4400 patients were followed for 4 years, metformin, glibenclamide and rosiglitazone did not have significantly different effects on the risk of death or cardiovascular events. A meta-analysis of ten randomised trials versus placebo or other hypoglycaemic drugs did not show that metformin monotherapy had a statistically significant effect on mortality. In the Cosmic trial, including more than 5000 patients, metformin monotherapy for one year was not more effective in reducing mortality than another oral hypoglycaemic drug. In the Spread-Dimcad trial in 304 diabetic patients with coronary artery disease, metformin monotherapy appeared to be more effective in preventing cardiovascular complications than glipizide after 5 years of follow-up. The adverse effects of metformin mainly consist of dose-dependent gastrointestinal disorders and rare cases or life-threatening lactic aciaosis. Kidney failure reduces metformin elimination. Metformin rarely causes hypoglycaemia and has no effect on body weight. It does not increase cancer-related mortality. It sometimes causes vitamin B12 deficiency leading

Chlorambucil has been considered for decades as a suitable therapeutic option for frail patients. Taking into account the advantage offered by the addition of MoAbs to chemotherapy, different studies up to now have explored the feasibility of chlorambucil-based chemoimmunotherapies in treatment-naïve CLL. COMPLEMENT1 is a prospective, randomized, open-label trial evaluating the efficacy and safety of ofatumumab added to chlorambucil, compared with chlorambucil in monotherapy, in the setting of untreated patients with CLL considered unsuitable for a fludarabine-based approach. Progression-free survival was significantly longer in the chemoimmunotherapy arm when compared with the single-agent chlorambucil (22.4 months versus 13.1 months). Response rate and quality were also improved in the combination arm. Furthermore, the addition of ofatumumab did not lead to an unmanageable toxicity. While the employment of anti-CD20 antibodies represents an advantage in the treatment of the CLL symptomatic population, at present different patient selection and treatment schedules do not allow a reliable comparison between chlorambucil-based regimens. The addition of ofatumumab to chlorambucil represents a further therapeutic gain in CLL. Longer follow up and direct comparison with other MoAbs are warranted to establish the preferred first-line treatment in elderly and unfit patients. PMID:27493712

    Background The aim was to analyse trends in clinically relevant resistance to first-line antiretroviral drugs in Spain, applying the Stanford algorithm, and to compare these results with reported Transmitted Drug Resistance (TDR) defined by the 2009 update of the WHO SDRM list. Methods We analysed 2781 sequences from ARV naive patients of the CoRIS cohort (Spain) between 2007–2011. Using the Stanford algorithm “Low-level resistance”, “Intermediate resistance” and “High-level resistance” categories were considered as “Resistant”. Results 70% of the TDR found using the WHO list were relevant for first-line treatment according to the Stanford algorithm. A total of 188 patients showed clinically relevant resistance to first-line ARVs [6.8% (95%Confidence Interval: 5.8–7.7)], and 221 harbored TDR using the WHO list [7.9% (6.9–9.0)]. Differences were due to a lower prevalence in clinically relevant resistance for NRTIs [2.3% (1.8–2.9) vs. 3.6% (2.9–4.3) by the WHO list] and PIs [0.8% (0.4–1.1) vs. 1.7% (1.2–2.2)], while it was higher for NNRTIs [4.6% (3.8–5.3) vs. 3.7% (3.0–4.7)]. While TDR remained stable throughout the study period, clinically relevant resistance to first line drugs showed a significant trend to a decline (p = 0.02). Conclusions Prevalence of clinically relevant resistance to first line ARVs in Spain is decreasing, and lower than the one expected looking at TDR using the WHO list. Resistance to first-line PIs falls below 1%, so the recommendation of screening for TDR in the protease gene should be questioned in our setting. Cost-effectiveness studies need to be carried out to inform evidence-based recommendations. PMID:24637804

    Standard systemic therapeutic agents used in acne include oral antimicrobials, isotretinoin, and hormonal agents. Appropriate patient selection is the key to decide when to use hormonal agents as first-line therapy as well as to achieve optimal results. Indications of hormonal therapy in acne in girls and women include proven ovarian or adrenal hyperandrogenism, recalcitrant acne, acne not responding to repeated courses of oral isotretinoin, acne tarda, polycystic ovary syndrome, or the presence of clinical signs of hyperandrogenism such as androgenic alopecia or the presence of the seborrhea, acne, hirsutism, alopecia syndrome. We describe the hormonal agents currently available for acne treatment, discuss their indications and contraindications, and address the question of whether they may be used as a first-line therapy in acne.

    Introduction Tracheal stenosis following intubation is the most common indication for tracheal resection and reconstruction. Endoscopic dilation is almost always associated with recurrence. This study investigated first-line surgical resection and anastomosis performed in fit patients presenting with postintubation tracheal stenosis. Methods Between February 2011 and November 2014, a prospective study was performed involving patients who underwent first-line tracheal resection and primary anastomosis after presenting with postintubation tracheal stenosis. Results A total of 30 patients (20 male) were operated on. The median age was 23.5 years (range: 13-77 years). Seventeen patients (56.7%) had had previous endoscopic tracheal dilation, four (13.3%) had had tracheal stents inserted prior to surgery and one (3.3%) had undergone previous tracheal resection. Nineteen patients (63.3%) had had a tracheostomy. Eight patients (26.7%) had had no previous tracheal interventions. The median time of intubation in those developing tracheal stenosis was 20.5 days (range: 0-45 days). The median length of hospital stay was 10.5 days (range: 7-21 days). The success rate for anastomoses was 96.7% (29/30). One patient needed a permanent tracheostomy. The in-hospital mortality rate was 3.3%: 1 patient died from a chest infection 21 days after surgery. There was no mortality or morbidity in the group undergoing first-line surgery for de novo tracheal lesions. Conclusions First-line tracheal resection with primary anastomosis is a safe option for the treatment of tracheal stenosis following intubation and obviates the need for repeated dilations. Endoscopic dilation should be reserved for those patients with significant co-morbidities or as a temporary measure in non-equipped centres. PMID:27138847

  7. Has the time come to abandon efavirenz for first-line antiretroviral therapy?

    PubMed

    2014-07-01

    Efavirenz has been recommended as a preferred third agent together with two nucleos(t)ides for first-line combination antiretroviral therapy (ART) for >15 years. The availability of efavirenz in a fixed-dose combination makes it very attractive. However, because of (i) adverse events associated with efavirenz, (ii) a poorer overall efficacy of efavirenz compared with newer antiretrovirals, (iii) the ranking of efavirenz as FDA Pregnancy Category D and (iv) the relatively high prevalence of transmitted drug-resistance mutations, there is a need to reconsider the role of efavirenz in first-line ART. We review the available evidence that challenges efavirenz's current position in first-line HIV treatment guidelines. Apart from its animal teratogenic potential, and moderate neuropsychiatric adverse events associated with its use, efavirenz has recently been associated with an increased risk of suicidality when compared with other antiretroviral drugs. Most importantly, efavirenz has demonstrated overall inferior efficacy to various comparator drugs, which include rilpivirine, raltegravir and dolutegravir, in antiretroviral-naive patients. Furthermore, epidemiological data indicate that the prevalence of non-nucleoside reverse transcriptase inhibitor resistance has reached 5%-8% in various parts of the world, and minority transmitted non-nucleoside reverse transcriptase inhibitor resistance-associated mutations can have a negative impact on the outcome of first-line efavirenz-based ART. Based on considerations of efficacy, toxicity and resistance, it is time to reconsider the routine use of efavirenz in ART. This, of course, presupposes that other antiretrovirals will be available in place of efavirenz, and may not be applicable in certain developing country settings where this is not the case.

    2009-05-01

    The development of Bcr-Abl tyrosine kinase inhibitors has dramatically changed the prognosis of patients with newly diagnosed chronic myeloid leukemia (CML). Standard-dose imatinib (400 mg/day in chronic phase, 600 mg/day in advanced CML) now dominates the management of this disease, producing considerably higher hematologic, cytogenetic, and molecular response rates than seen with previous drug therapies. However, although many patients respond well to standard-dose imatinib initially, some patients do not achieve adequate levels of response or discontinue therapy because of resistance. One approach to improving treatment response with first-line imatinib may be to increase the imatinib dose (800 mg/day), although recent trial data indicate that overall increases in response rates may be modest. Newer Bcr-Abl tyrosine kinase inhibitors can induce responses in patients with all phases of imatinib-resistant CML, even those with imatinib-resistant mutations in the BCR-ABL gene. Furthermore, in initial studies, first-line dasatinib or nilotinib treatment has produced response rates that compare favorably with historical controls treated with imatinib, although confirmation is required from head-to-head clinical trials. Future clinical approaches may include drug combinations, which may allow quiescent leukemia stem cells to be eradicated. Further improvements in drug treatment for first-line CML are expected during the next few years. PMID:19306355

    This paper presents a summary of the evidence review group (ERG) report into the clinical effectiveness and cost-effectiveness of cetuximab for the first-line treatment of metastatic colorectal cancer (mCRC), in accordance with the licensed indication, based upon the manufacturer's submission to the National Institute for Health and Clinical Excellence (NICE) as part of the single technology appraisal process. The ERG project ran between 22 January 2008 and 4 November 2008. The clinical evidence came from two unpublished randomised controlled trials (RCTs) of cetuximab plus chemotherapy versus chemotherapy alone in the first-line treatment of mCRC. A third RCT submitted later compared cetuximab with irinotecan in combination with 5-fluorouracil (5-FU) and folinic acid (FA) and cetuximab with oxaliplatin in combination with 5-FU and FA in patients with mCRC with liver metastases only. No published economic evaluations of cetuximab for first-line chemotherapy in mCRC were identified in the submission. A de novo model examined the cost-effectiveness of cetuximab in patients with mCRC that was epidermal growth factor receptor positive, k-ras wild type and with liver metastases. The main source of clinical effectiveness evidence came from the first two RCTs which provided follow up information for 1-2 years. Secondary information was used to estimate survival for a further 22 years. The model focused on the patients for whom the treatment had been licensed. This limited the applicability of the model to the NHS setting in which patients would be a mixture of k-ras wild type and mutations and also a mixture of patients with liver metastases and other metastases. The difference in progression-free survival for the two trials was between 0.5 to 1.2 months over a 7-10 month period. Eight months' treatment with cetuximab, given as an initial loading dose and then weekly until progression, would cost around 22,932 pounds for an average man and 18,427 pounds for an average

    Background. Virologic failure (VF) on a first-line ritonavir-boosted protease inhibitor (PI/r) regimen is associated with low rates of resistance, but optimal management after failure is unknown. Methods. The analysis included participants in randomized trials who experienced VF on a first-line regimen of PI/r plus 2 nucleoside reverse transcriptase inhibitors (NRTIs) and had at least 24 weeks of follow-up after VF. Antiretroviral management and virologic suppression (human immunodeficiency virus type 1 [HIV-1] RNA <400 copies/mL) after VF were assessed. Results. Of 209 participants, only 1 participant had major PI-associated treatment-emergent mutations at first-line VF. The most common treatment approach after VF (66%) was to continue the same regimen. The virologic suppression rate 24 weeks after VF was 64% for these participants, compared with 72% for those who changed regimens (P = .19). Participants remaining on the same regimen had lower NRTI resistance rates (11% vs 30%; P = .003) and higher CD4+ cell counts (median, 275 vs 213 cells/µL; P = .005) at VF than those who changed. Among participants remaining on their first-line regimen, factors at or before VF significantly associated with subsequent virologic suppression were achieving HIV-1 RNA <400 copies/mL before VF (odds ratio [OR], 3.39 [95% confidence interval {CI}, 1.32–8.73]) and lower HIV-1 RNA at VF (OR for <10 000 vs ≥10 000 copies/mL, 3.35 [95% CI, 1.40–8.01]). Better adherence after VF was also associated with subsequent suppression (OR for <100% vs 100%, 0.38 [95% CI, .15–.97]). For participants who changed regimens, achieving HIV-1 RNA <400 copies/mL before VF also predicted subsequent suppression. Conclusions. For participants failing first-line PI/r with no or limited drug resistance, remaining on the same regimen is a reasonable approach. Improving adherence is important to subsequent treatment success. PMID:24842909

    Candida species are the leading causes of invasive fungal infection among hospitalized patients and are responsible for major economic burdens. The goals of this study were to estimate the costs directly associated with the treatment of candidemia and factors associated with increased costs, as well as the impact of first-line antifungal agents on the outcomes and costs. A retrospective study was conducted in a sample of 199 patients from four university-affiliated tertiary care hospitals in Korea over 1 year. Only costs attributable to the treatment of candidemia were estimated by reviewing resource utilization during treatment. Risk factors for increased costs, treatment outcome, and hospital length of stay (LOS) were analyzed. Approximately 65% of the patients were treated with fluconazole, and 28% were treated with conventional amphotericin B. The overall treatment success rate was 52.8%, and the 30-day mortality rate was 47.9%. Hematologic malignancy, need for mechanical ventilation, and treatment failure of first-line antifungal agents were independent risk factors for mortality. The mean total cost for the treatment of candidemia was $4,743 per patient. Intensive care unit stay at candidemia onset and antifungal switch to second-line agents were independent risk factors for increased costs. The LOS was also significantly longer in patients who switched antifungal agents to second-line drugs. Antifungal switch to second-line agents for any reasons was the only modifiable risk factor of increased costs and LOS. Choosing an appropriate first-line antifungal agent is crucial for better outcomes and reduced hospital costs of candidemia. PMID:22526315

    Chemotherapy is of crucial importance in advanced gastric cancer (AGC) patients, in order to obtain palliation of symptoms and improve survival. To date, no standard chemotherapy regimen has been established for AGC. The purpose of the present study was to evaluate the efficacy and toxicity of the combination regimen of paclitaxel and capecitabine (PX) as first-line chemotherapy in patients with advanced or recurrent gastric cancer. Patients with advanced or recurrent gastric cancer who were treated with PX as first-line chemotherapy between January 2001 and December 2012 at the Zhejiang Cancer Hospital (Hangzhou, China) were retrospectively investigated. Survival was evaluated using the Kaplan-Meier method. In total, 36 patients were enrolled, with a median age of 53.5 years and a Karnofsky performance status (KPS) score of ≥80. A median of 4 PX cycles were administered (range, 2-8 cycles). The median progression-free survival time was 3.7 months [95% confidence interval (CI), 2.9-4.5 months) and the median overall survival time was 12.0 months (95% CI, 9.8-14.1 months). From the 36 patients evaluated, one (2.8%) achieved a complete response, seven (19.4%) achieved a partial response, 24 (66.7%) exhibited stable disease and four (11.1%) exhibited progressive disease. The objective response rate was 22.2% (8/36), and the disease control rate was 88.9% (32/36). All 36 patients were assessed for treatment toxicity. Grade 3 or 4 adverse events included neutropenia (2.8% of patients), hand-foot syndrome (2.8%) and vomiting (2.8%). No neutropenic fever or treatment-related mortalities were observed. PX combination chemotherapy may be a valuable first-line therapy for advanced or recurrent gastric cancer. PMID:24959275

    Background: The spread of drug-resistant tuberculosis (TB) is one of the major public health problems through the world. Surveillance of anti-TB drug resistance is essential for monitoring of TB control strategies. The occurrence of drug resistance, particularly multi-drug resistance Mycobacterium tuberculosis (MDR), defined as resistance to at least rifampicin (RIF) and isoniazid (INH), has become a significant public health dilemma. The status of drug-resistance TB in Iran, one of the eastern Mediterranean countries locating between Azerbaijan and Armenia and high-TB burden countries (such as Afghanistan and Pakistan) has been reported inconsistently. Therefore, the aim of this study was to summarize reports of first-line anti-tubercular drug resistance in M. tuberculosis in Iran. Material and Methods: We systematically reviewed published studies on drug-resistant M. tuberculosis in Iran. The search terms were “Mycobacterium tuberculosis susceptibility” or “Mycobacterium tuberculosis resistant” and Iran. Results: Fifty-two eligible articles, published during 1998–2014, were included in this review. Most of the studies were conducted in Tehran. The most common used laboratory method for detecting M. tuberculosis drug resistant was Agar proportion. The highest resistance to first-line drugs was seen in Tehran, the capital city of Iran. The average prevalence of isoniazid (INH), rifampin (RIF), streptomycin (SM), and ethambotol (EMB) resistance via Agar proportion method in Tehran was 26, 23, 22.5, and 16%, respectively. In general, resistance to INH was more common than RIF, SM, and EMB in Tehran Conclusions: In conclusion, this systematic review summarized the prevalence and distribution of first-line anti-tubercular drug resistance of M. tuberculosis in Iran. Our results suggested that effective strategies to minimize the acquired drug resistance, to control the transmission of resistance and improve the diagnosis measures for TB control in Iran. PMID

    Dolutegravir (DTG) is an HIV integrase inhibitor that was recently approved for therapy by the Food and Drug Administration in the United States. When used as part of first-line therapy, DTG is the only HIV drug that has not selected for resistance mutations in the clinic. We believe that this is due to the long binding time of DTG to the integrase enzyme as well as greatly diminished replication capacity on the part of viruses that might become resistant to DTG. We further speculate that DTG might be able to be used in strategies aimed at HIV eradication. PMID:25166745

    The treatment of metastatic colorectal cancer (mCRC) has evolved considerably in the last decade, currently allowing most mCRC patients to live more than two years. Monoclonal antibodies targeting the epidermal growth factor receptor (EGFR) and vascular endothelial growth factor play an important role in the current treatment of these patients. However, only antibodies directed against EGFR have a predictive marker of response, which is the mutation status of v-Ki-ras2 Kirsten rat sarcoma viral oncogene homolog (KRAS). Cetuximab has been shown to be effective in patients with KRAS wild-type mCRC. The CRYSTAL study showed that adding cetuximab to FOLFIRI (regimen of irinotecan, infusional fluorouracil and leucovorin) significantly improved results in the first-line treatment of KRAS wild-type mCRC. However, results that evaluate the efficacy of cetuximab in combination with oxaliplatin-based chemotherapy in this setting are contradictory. On the other hand, recent advances in the management of colorectal liver metastases have improved survival in these patients. Adding cetuximab to standard chemotherapy increases the response rate in patients with wild-type KRAS and can thus increase the resectability rate of liver metastases in this group of patients. In this paper we review the different studies assessing the efficacy of cetuximab in the first-line treatment of mCRC. PMID:24764659

    Choice of first line treatment for patients with metastatic colorectal cancer (mCRC) is based on tumour and patient related factors and molecular information for determination of individual treatment aim and thus treatment intensity. Recent advances (e.g., extended RAS testing) enable tailored patient assignment to the most beneficial treatment approach. Besides fluoropyrimidines, irinotecan and oxaliplatin, a broad variety of molecular targeting agents are currently available, e.g., anti-angiogenic agents (bevacizumab) and epidermal growth factor receptor (EGFR) antibodies (cetuximab, panitumumab) for first line treatment of mCRC. Although some combinations should be avoided (e.g., oral or bolus fluoropyrimidines, oxaliplatin and EGFR antibodies), treatment options range from single agent to highly effective four-drug regimen. Preliminary data comparing EGFR antibodies and bevacizumab, both with chemotherapy, seem to favour EGFR antibodies in RAS wildtype disease. However, choosing the most appropriate treatment approach for mCRC patients remains a complex issue, with numerous open questions. PMID:24574764

    Preterm birth is defined as delivery before 37 weeks. It is the leading cause of perinatal morbidity and mortality. Spontaneous preterm birth accounts for approximately 70% of all preterm births. Postponing delivery for 48 hours in order to allow administration of corticosteroids, magnesium for neuroprotection and in order to transfer women to a center with neonatal intensive care unit are the goals of tocolytic therapy. The benefits of tocolytic therapy between 24.0 and 34.0 weeks of gestation outweigh the risk of maternal and fetal complications and it should be initiated provided no contraindications exist. Tocolytic agents that have been used are: prostaglandin synthetase inhibitors, calcium channel antagonists, B-adrenergic agonists, magnesium and oxytocin receptor antagonists. All drugs have demonstrated limited benefit that consists mainly of prolonging the gestational age for 48 hours, without a reduction in the incidence of perinatal mortality and morbidity. Additionally, most available tocolytic agents carry inherent risks of adverse effects. According to the American College of Obstetricians and Gynecologists recommendations, there is no clear first line tocolytic drug to manage preterm labor. Other subjects of debate related to the use of tocolytic therapy include: The effectiveness of combination therapy, the use of tocolytic therapy in multiple pregnancies and the use of progesterone as an adjuvant therapy. We will address the efficacy and tolerability of the tocolytic agents available, the issue of maintenance therapy and debates mentioned above, and try to suggest a first line tocolytic agent based on a study performed at our institution.

    Although electroconvulsive therapy (ECT) has generally been reserved for patients refractory to other forms of treatment, its use as a first-line treatment, prior to the use of other biologic approaches, has occasionally been mentioned in the literature on the treatment of affective disorders and, when indicated, can prove rapidly effective and even life saving. The present study retrospectively reviewed 27 cases treated over the span of a decade in which ECT was chosen as the first treatment of an affective episode. In none of these cases was antidepressant medication or other biologic approaches used for the current episode. A clinical global rating scale was employed to measure improvement. Although the majority of such patients were treated with ECT first based upon the severity of their depressive illness, 13 received ECT because of their obtunded condition and these patients, initially diagnosed as catatonic on admission, were suspected of having a bipolar condition, as revealed on their discharge diagnosis. In addition, ECT was recommended preferentially in 4 patients because they were pregnant and in another 4 because it had worked well in the past; an additional patient received ECT first because of his fragile medical condition. Almost all patients recovered and none suffered serious adverse effects. Sample case histories are provided along with tentative guidelines for the consideration of first-line use of ECT in clinically difficult cases. PMID:15167428

    Objective To determine the maximum tolerated dose (MTD), dose-limiting toxicity (DLT) and efficacy of sorafenib in combination with FOLFOX4 (oxaliplatin/leucovorin (LV)/5-fluorouracil) as first-line treatment for advanced gastric cancer, we performed a phase I dose-finding study in nine evaluable patients with unresectable locally advanced or metastatic gastric cancer or gastroesophageal junction adenocarcinoma. Methods According to modified Fibonacci method, the design of this study was to guide elevation of the sorafenib dosage to the next level (from 200 mg twice daily to 400 mg twice daily and then, if tolerated, 600 mg twice daily). If the patient achieved complete response (CR), partial response (PR) or stable disease (SD) after eight cycles of treatment, combination chemotherapy was scheduled to be discontinued and sorafenib monotherapy continued at the original dose until either disease progression or unacceptable toxicity. Results In sorafenib 200 mg twice daily group, DLT was observed in 1 of 6 patients, and in 400 mg twice daily group, it was observed in 2 of 3 patients. Seven of 9 (77.8%) evaluable patients achieved PR, with a median overall survival (OS) of 11.8 [95% confidence interval (CI): 8.9-14.7] months. Common adverse effects include hand-foot syndrome, leukopenia, neutropenia, anorexia, and nausea. Conclusions Twice-daily dosing of sorafenib 200 mg in combination with FOLFOX4 was proven effective and safe for the treatment of advanced gastric cancer, and could be an appropriate dosage for subsequent phase II clinical studies.

    Systemic chemotherapy comprising anthracycline monotherapy is the standard regimen for metastatic soft tissue sarcomas, particularly leiomyosarcomas, which have limited sensitivity to ifosfamide. However, the optimal chemotherapy regimen for elderly patients, especially those considered unfit for anthracyclines, is undefined. Trabectedin is a potent marine-derived antineoplastic drug with documented activity in liposarcomas and leiomyosarcomas. It is registered in Europe for the treatment of adult patients with advanced soft tissue sarcoma, after failure of anthracyclines and ifosfamide, or who are unsuited to receive these agents. We report the long-term response to first-line trabectedin therapy in an elderly patient with metastatic leiomyosarcoma unfit for standard therapy. A 66-year-old woman underwent resection of a pelvic epithelioid leiomyosarcoma with positive margins in December 2002, followed by postoperative radiotherapy. In February 2012, she was diagnosed with multiple lung lesions and local relapse in the pelvis. As she was considered unsuitable for both anthracycline and ifosfamide because of cardiovascular comorbidities and because she was highly anxious at the prospect of developing alopecia, vomiting, and fatigue, we commenced treatment with trabectedin at 75% of the standard dose of 1.5 mg/m2 every 3 weeks. Treatment was well tolerated, and the patient continued treatment for 25 cycles, with disease stabilization according to the RECIST criteria and a partial response according to the Choi criteria. Disease progression was observed in November 2013 and the patient died 20 months after the diagnosis of metastases. Trabectedin may represent an alternative option for highly selected elderly patients with metastatic sarcoma and unfit for anthracyclines; careful monitoring of toxicities is strongly recommended.

We report the long-term response to first-line trabectedin therapy in an elderly patient with metastatic leiomyosarcoma unfit for standard therapy. A 66-year-old woman underwent resection of a pelvic epithelioid leiomyosarcoma with positive margins in December 2002, followed by postoperative radiotherapy. In February 2012, she was diagnosed with multiple lung lesions and local relapse in the pelvis. As she was considered unsuitable for both anthracycline and ifosfamide because of cardiovascular comorbidities and because she was highly anxious at the prospect of developing alopecia, vomiting, and fatigue, we commenced treatment with trabectedin at 75% of the standard dose of 1.5 mg/m every 3 weeks. Treatment was well tolerated, and the patient continued treatment for 25 cycles, with disease stabilization according to the RECIST criteria and a partial response according to the Choi criteria. Disease progression was observed in November 2013 and the patient died 20 months after the diagnosis of metastases. Trabectedin may represent an alternative option for highly selected elderly patients with metastatic sarcoma and unfit for anthracyclines; careful monitoring of toxicities is strongly recommended.

    This document describes the recommendations of a group of scientific societies concerning the first-line therapeutic approach to paediatric tuberculosis (TB). The treatment of pulmonary TB should be based on the existence of parenchymal involvement and the risk of antibiotic resistance. The treatment of extra-pulmonary TB is based on the regimens used for severe pulmonary TB. The administration of corticosteroids is recommended only in cases of miliary TB, tuberculous meningitis and tuberculous pericarditis. Vitamin B6 may be indicated in the case of isoniazid-treated TB in breastfeeding infants, severely malnourished subjects, or patients with other diseases at high risk of vitamin deficiency. Once having started treatment, children with TB should be carefully followed up in order to evaluate compliance, the response to treatment, the need for treatment changes, and the presence of drug-related adverse events. Primary care paediatricians can support reference centres in providing family healthcare education and encouraging treatment compliance. PMID:26612773

    This text summarizes the CLAFU first-line screening guidelines for renal stone disease patients. We have focused on the useful information provided by renal stone analysis and also the identification of relevant stone risk factors detected in a 24-hour urine collection. Indeed, evaluation of water, sodium and protein intake may be easily achieved in a current clinical setting and allows a useful pedagogic tool for patients' advices and follow-up: daily diuresis above 2000 mL, calcium intake between 800 mg and 1 g/day, a moderate daily sodium and proteins restricted diet (<9 g and <1.2 g/kg per day respectively). General therapeutical principles are reviewed, including circumstances requiring specialized management. PMID:24365623

    The debate on the optimal drug combination for treating chemotherapy-naïve patients with metastatic colorectal cancer has recently become particularly heated. The present editorial will review recent data on this topic. The FIRE-3 and PEAK trials have shown a 7.5 to 12 mo survival advantage with the use anti-epidermal growth factor receptor (anti-EGFR) antibodies. The CALGB 80405 has shown no difference between anti-EGFR and anti-vascular endothelial growth factor agents. All three trials have consistently shown a significant increase in objective response rate. These data suggest that there is a subset of metastatic colorectal cancer patients, rigorously selected by molecular profiling, who particularly benefit from an anti-EGFR-based regimen in the first-line setting.

    The transvaginal access for exploration of tubo-ovarian function in women with unexplained infertility has been revived since transvaginal hydrolaparoscopy (THL) was introduced in 1998. One prospective double-blind trial and several reviews have validated the diagnostic value of THL in comparison with laparoscopy for the exploration of women with unexplained infertility. A review of the recent literature confirms the efficacy and safety of the technique for first-line endoscopy-based exploration of fertility. The standard policy of 1-year delay for laparoscopic investigation in unexplained infertility is challenged. In older women and particularly in women experienced in fertility awareness methods, THL and minihysteroscopy can be performed after a waiting period of 6-12 months. PMID:22674201

    Current guidelines include atrial fibrillation (AF) catheter ablation as part of the management strategy in patients that have failed at least one oral antiarrhythmic drug treatment course. However, growing evidence derived from both randomized and non-randomized studies demonstrate lower rates of AF recurrence and AF burden in patients with paroxysmal AF that are naïve to antiarrhythmic drug treatment. Furthermore, progression from paroxysmal AF to persistent AF appears to be delayed by early catheter ablation of AF. The current review addresses the question of the best timing for ablation in patients with paroxysmal AF and provides the rationale for offering AF ablation as first-line therapy based on the most updated evidence available.

    Tyrosine kinase inhibitors (TKIs) have contributed to marked improvements in survival in patients with chronic myeloid leukaemia (CML). This article discusses the place of the second-generation TKIs dasatinib and nilotinib in the first-line treatment of CML and is based on published literature. The new agents are more potent and effective than imatinib. Data from pivotal clinical trials indicate that response to dasatinib and nilotinib is greater and more rapid than that to imatinib, resulting in a higher probability of patients achieving an optimal response to treatment. Differences between the newer agents with respect to patient groups for whom caution is advised, drug interaction potential, haematological toxicity, pulmonary toxicity, changes in the immune system and effects on laboratory parameters are discussed. With similar levels of efficacy, the choice of second-generation agents should be guided by the characteristics of the individual patient and the most suitable dosing regimen. PMID:24043361

    AIM: To evaluate long-term outcomes of radiofrequency (RF) ablation as first-line therapy for single hepatocellular carcinoma (HCC) ≤ 3 cm and to determine survival and prognostic factors. METHODS: We included all 184 patients who underwent RF ablation as a first-line treatment for single HCC ≤ 3 cm between April 2005 and December 2013. According to the criteria of Livraghi, the 184 patients were divided into two groups: those suitable for surgical resection (84 cases) and those unsuitable for surgical resection (100 cases). The primary endpoints were the overall survival (OS) rate and safety; the secondary endpoints were primary technique effectiveness and recurrence rate. RESULTS: There were 19 (10.3%) cases of ablation related minor complications. The complete tumor ablation rate after one RF session was 97.8% (180/184). The rate of local tumor progression, extrahepatic metastases and intrahepatic distant recurrence were 4.9% (9/184), 9.8% (18/184) and 37.5% (69/184), respectively. In the 184 patients, the 1-, 3-, and 5-year OS rates were 99.5%, 81.0%, and 62.5%, respectively. The 1-, 3-, and 5-year OS rates were 100%, 86.9%, and 71.4%, respectively, in those suitable for surgical resection and 99.0%, 76.0%, and 55.0%, respectively, in those unsuitable for surgical resection (P = 0.021). On univariate and multivariate analyses, poorer OS was associated with Child-Pugh B class and portal hypertension (P < 0.05). CONCLUSION: RF ablation is a safe and effective treatment for single HCC ≤ 3 cm. The OS rate of patients suitable for surgical resection was similar to those reported in surgical series.

    The discovery of endothelial growth factor receptor (EGFR) mutations has laid the foundations for personalized medicine in non-small cell lung carcinoma (NSCLC). In phase III trials, the first-generation tyrosine kinase inhibitors (TKI), gefitinib and erlotinib, demonstrated greater efficacy compared with chemotherapy in patients with EGFR mutations, achieving progression-free survival of 8-13.5 months. Afatinib, a second-generation irreversible pan-ErbB inhibitor, is the first TKI that has shown a benefit in overall survival (OS) compared with chemotherapy in EGFR mutation-positive NSCLC when used as first-line treatment. Exon 19 deletion (Del19) and the single-point substitution mutation (L858R) in exon 21, called activating mutations due to their ability to confer sensitivity to TKI, represent approximately 90% of the EGFR mutations in NSCLC. Distinct sensitivity to TKI has been observed depending on the type of mutation, with greater progression-free survival in patients with the Del19 mutation. The analysis of OS in the LUX-Lung 3 and LUX-Lung 6 trials showed a statistically significant increase in survival in afatinib-treated patients with the Del 19 mutation, but no significant increase in that of patients with the L858R mutation. Direct comparison of afatinib and gefitinib as first-line therapy (LUX-Lung 7 trial) showed a statistically-significant increase in progression-free survival (hazard ratio: 0.73; 95% confidence interval, 0.57-0.95; p=0.0165) with afatinib. In the analysis by type of mutation, this benefit was observed for both the Del19 and the L858R mutations. PMID:27426243

    Background: Few reports have described endoscopic ultrasound (EUS)-guided fine needle aspiration (FNA) for biliary lesions. In addition, adverse events were not completely examined in previous reports, due to the inclusion of cases in which biliary stents had already been placed. The present study aimed to investigate the diagnostic yield and adverse events of EUS-FNA for biliary lesions as the first-line diagnostic modality for consecutive prospectively registered patients. Methods: Inclusion criteria were as follows: (1) patients with suspected cholangiocarcinoma (CCA) based on computed tomography or other imaging modalities; (2) patients who had not previously undergone endoscopic retrograde cholangiopancreatography or EUS-FNA; (3) absence of surgically altered anatomy, such as Roux-en-Y anastomosis or duodenal obstruction caused by tumor invasion, through which an endoscope could not pass; and (4) provision of written informed consent to all procedures associated with the study. Results: A total of 47 consecutive patients with suspected CCA were registered to this study. Sensitivity and accuracy were 89% and 87%, respectively. On multivariate analysis, puncture site was the only factor associated with reduced diagnostic yield (hazard ration, 6.879; 95% confidence interval, 1.172–40.374; P = 0.033). Remarkably, no adverse events such as bleeding or bile leakage were associated with EUS-FNA in any of the 47 patients. Conclusions: Our results suggest that EUS-FNA can be safely performed for biliary disease without biliary stenting. Furthermore, this procedure may warrant use as the first-line diagnostic method, although our results need to be validated in future prospective studies. PMID:27134660

    Follicular lymphoma (FL) is a clinically and molecularly heterogeneous disease. Posttreatment surrogate end points, such as progression of disease within 24 months (POD24) are promising predictors for overall survival (OS) but are of limited clinical value, primarily because they cannot guide up-front treatment decisions. We used the clinical and molecular data from 2 independent cohorts of symptomatic patients in need of first-line immunochemotherapy (151 patients from a German Low-Grade Lymphoma Study Group [GLSG] trial and 107 patients from a population-based registry of the British Columbia Cancer Agency [BCCA]) to validate the predictive utility of POD24, and to evaluate the ability of pretreatment risk models to predict early treatment failure. POD24 occurred in 17% and 23% of evaluable GLSG and BCCA patients, with 5-year OS rates of 41% (vs 91% for those without POD24, P < .0001) and 26% (vs 86%, P < .0001), respectively. The m7-FL International Prognostic Index (m7-FLIPI), a prospective clinicogenetic risk model for failure-free survival, had the highest accuracy to predict POD24 (76% and 77%, respectively) with an odds ratio of 5.82 in GLSG (P = .00031) and 4.76 in BCCA patients (P = .0052). A clinicogenetic risk model specifically designed to predict POD24, the POD24-PI, had the highest sensitivity to predict POD24, but at the expense of a lower specificity. In conclusion, the m7-FLIPI prospectively identifies the smallest subgroup of patients (28% and 22%, respectively) at highest risk of early failure of first-line immunochemotherapy and death, including patients not fulfilling the POD24 criteria, and should be evaluated in prospective trials of precision medicine approaches in FL.

    This systematic review aims to analyze the case reports, case series, or clinical studies describing the women with cesarean scar ectopic pregnancy (CSEP), and thus, to determine the efficacy and safety of different primary treatment modalities in the management of CSEP. A thorough search of electronic databases showed that 274 articles on CSEP were published between January 1978 and April 2014. Systemic methotrexate, uterine artery embolization, dilatation and curettage (D&C), hysterotomy, and hysteroscopy were the most frequently adopted first-line approaches. The success rates of systemic methotrexate, uterine artery embolization, hysteroscopy, D&C, and hysterotomy were 8.7%, 18.3%, 39.1%, 61.6%, and 92.1%, respectively. The hysterectomy rates were 3.6%, 1.1%, 0.0%, 7.3%, and 1.7% in CSEP cases that were treated by systemic methotrexate, uterine artery embolization, hysteroscopy, D&C, and hysterotomy, respectively. The ability to achieve a subsequent term pregnancy is related to successful systemic methotrexate treatment (p = 0.001) or hysterotomy (p = 0.009). Future term pregnancy was significantly more frequent in the hysterotomy group (p = 0.001). Hysteroscopy and laparoscopic hysterotomy are safe and efficient surgical procedures that can be adopted as primary treatment modalities for CSEP. Uterine artery embolization should be reserved for cases with significant bleeding and/or a high suspicion index for arteriovenous malformation. Systemic methotrexate and D&C are not recommended as first-line approaches for CSEP, as these procedures are associated with high complication and hysterectomy rates. PMID:27125412

    Changes in diagnosis and treatment of rheumatoid arthritis oblige us to question clinical practice. Evidence demonstrates that the combination of biologics and methotrexate in rapid increments leads to larger remission rates than methotrexate alone. The combination has a faster clinical response in activity, physical function, quality of life, fatigue and sleep. But the most significant effect of biologics is on radiographic progression. The reduction in radiological damage has a spectrum that goes from anti-TNF+methotrexate to anti-TNF monotherapy, being less with methotrexate, and independent from improvement in activity; it occurs with all of the anti-TNF drugs and with other targets with different mechanisms of action (anti-CD20, T cell costimulation inhibitors and anti IL-6). The clinical significance of this finding will be seen in the future, when more is known of its impact on the poor outcomes of RA patients. Because methotrexate is an excellent drug, it seems madness to say that all patients should receive biologics+methotrexate, but it is reasonable to consider that a subgroup must receive them from the start. The American College of Rheumatology recommends their use in patients with RA of less than 6 months since onset, with no previous exposure to methotrexate, persistent and elevated activity (<3 months) and poor prognostic factors or those with persistent and elevated activity (3-6 months) independent of poor prognostic factors, and if the patient "has insurance". A final thought would be: Is there a new treatment pyramid which has cost at its base now? PMID:21794638

    Objective Focusing on efficacy and tolerability, we compared linagliptin monotherapy with voglibose monotherapy in patients with type 2 diabetes undergoing hemodialysis (HD). Research design and methods In this multicenter, randomized, open-label, parallel-group, active-controlled study, 78 patients were randomized (1:1) to receive a 12-week treatment with 5 mg linagliptin once daily or 0.2 mg voglibose three times a day. To assess whether linagliptin was superior to voglibose, the primary efficacy end point was the change in glycated hemoglobin (HbA1c) level between baseline and week 12. Secondary efficacy end points included changes between baseline and week 12 in glycated albumin (GA) and casual plasma glucose (PG) levels. Results At week 12, the adjusted mean HbA1c levels had decreased by −0.60% after treatment with linagliptin and by −0.20% after treatment with voglibose (treatment difference: −0.40%, 95% CI −0.74% to −0.06%, p=0.022). A significant reduction in casual PG level was also observed after treatment with linagliptin compared with treatment with voglibose. Relative to voglibose, linagliptin tended to elicit reductions in GA, although without statistical significance. No hypoglycemic symptoms or severe hypoglycemia occurred during the study. Conclusions In patients with type 2 diabetes undergoing HD, linagliptin monotherapy provided significantly better glycemic control without severe hypoglycemia than voglibose monotherapy. Linagliptin represents a promising agent for glycemic management in patients with type 2 diabetes undergoing HD. Trial registration number UMIN000007635; results. PMID:27547421

    Background Medicines to control hypertension, a leading cause of morbidity and mortality, are a major component of health expenditures in the Philippines. This study aims to review economic studies for first line anti-hypertensive medical treatment without co-morbidities; and discuss practical, informational and policy implications on the use of economic evaluation in the Philippines. Methods A systematic literature review was performed using the following databases: MEDLINE, EMBASE, BIOSIS, PubMed, The Cochrane Library, Health Economics Evaluations Database (HEED) and the Centre for Reviews and Dissemination – NHS NICE. Six existing economic analytical frameworks were reviewed and one framework for critical appraisal was developed. Results Out of 1336 searched articles, 12 fulfilled the inclusion criteria. The studies were summarized according to their background characteristics (year, journal, intervention and comparators, objective/study question, target audience, economic study type, study population, setting and country and source of funding/conflict of interest) and technical characteristics (perspective, time horizon, methodology/modeling, search strategy for parameters, costs, effectiveness measures, discounting, assumptions and biases, results, cost-effectiveness ratio, endpoints, sensitivity analysis, generalizability, strengths and limitations, conclusions, implications and feasibility and recommendations). The studies represented different countries, perspectives and stakeholders. Conclusions Diuretics were the most cost-effective drug class for first-line treatment of hypertension without co-morbidities. Although the Philippine Health Insurance Corporation may apply the recommendations given in previous studies (i.e. to subsidize diuretics, ACE inhibitors and calcium channel blockers), it is uncertain how much public funding is justified.

    Background First-line postoperative adjuvant chemotherapies with S-1 and capecitabine and oxaliplatin (XELOX) were first recommended for resectable gastric cancer patients in the 2010 and 2011 Chinese NCCN Clinical Practice Guidelines in Oncology: Gastric Cancer; however, their economic impact in China is unknown. Objective The aim of this study was to compare the cost-effectiveness of adjuvant chemotherapy with XELOX, with S-1 and no treatment after a gastrectomy with extended (D2) lymph-node dissection among patients with stage II-IIIB gastric cancer. Methods A Markov model, based on data from two clinical phase III trials, was developed to analyse the cost-effectiveness of patients in the XELOX group, S-1 group and surgery only (SO) group. The costs were estimated from the perspective of Chinese healthcare system. The utilities were assumed on the basis of previously published reports. Costs, quality-adjusted life-years (QALYs) and incremental cost-effectiveness ratios (ICER) were calculated with a lifetime horizon. One-way and probabilistic sensitivity analyses were performed. Results For the base case, XELOX had the lowest total cost ($44,568) and cost-effectiveness ratio ($7,360/QALY). The relative scenario analyses showed that SO was dominated by XELOX and the ICERs of S-1 was $58,843/QALY compared with XELOX. The one-way sensitivity analysis showed that the most influential parameter was the utility of disease-free survival. The probabilistic sensitivity analysis predicted a 75.8% likelihood that the ICER for XELOX would be less than $13,527 compared with S-1. When ICER was more than $38,000, the likelihood of cost-effectiveness achieved by S-1 group was greater than 50%. Conclusions Our results suggest that for patients in China with resectable disease, first-line adjuvant chemotherapy with XELOX after a D2 gastrectomy is a best option comparing with S-1 and SO in view of our current study. In addition, S-1 might be a better choice, especially with a

    Studies concerning the eradication of Helicobacter pylori have resulted in a proliferation of meta-analyses. To date, there are 303 meta-analyses cited in PubMed, 113 dealing with the therapy of the infection. A chronological analysis of the results of meta-analyses performed between 1998 and 2010 shows that first-line standard triple therapies achieved eradication rates on an intention-to-treat basis of around 80%; prolonging treatment to 14, but not 10 d should improve the results. The proton pump inhibitors have a similar efficiency, and giving a double dose is more efficient than the standard doses of these drugs. Triple and quadruple therapies proved to be equivalent. Based on meta-analytical data, the decrease in efficiency over time cannot be substantiated: eradication rates < 80% followed from the introduction of triple therapies. As alternatives, ranitidine bismuth citrate-, levofloxacin- or furazolidone-based therapies were shown to obtain the same eradication rates as standard triple regimens. Sequential therapies and quadruple non-bismuth-based therapies were superior to standard triple therapies but their use is limited to certain countries. In the author's opinion, and from a meta-analytical viewpoint, standard triple therapies cannot yet be considered obsolete. Furthermore, non-inferiority trials are proposed for the future, including assessment of local contemporary antimicrobial resistance profiles and the CagA and CYP2C19 status of the enrolled patients.

    Objective. The eradication rate of Helicobacter pylori (H. pylori) following standard triple therapy has declined over the past few decades. This study has determined whether high dose dual therapy (PPI and amoxicillin) is adequate for eradicating H. pylori in Korea. Methods. This was an open-labeled study of H. pylori infected treatment-naive patients. Subjects received dual therapy for 14 days: ilaprazole 40 mg tablets given twice a day and amoxicillin 750 mg tablets given 4 times a day. At the end of the therapy, the subjects visited the clinic to confirm compliance and monitor for any side effects. Subjects visited again after 4–6 weeks to confirm H. pylori status through a urea breath test. Results. The cure rate of H. pylori was 79.3% (23 of 29) (95% confidence interval: 61.6–90.2) in the intention-to-treat analysis and 82.1% (23 of 28) in the per-protocol analysis. Compliance rates were high (96.6%) and side effects were minimal and tolerable. Conclusion. A high dose of ilaprazole + amoxicillin was ineffective as the first-line therapy for eradicating H. pylori in Korea. Future studies should focus on intragastric pH measurements and assess amoxicillin resistance. PMID:27413365

    The introduction of second-generation tyrosine-kinase inhibitors (TKIs) has generated a lively debate on the choice of first-line TKI in chronic phase, chronic myeloid leukemia (CML). Despite the TKIs have different efficacy and toxicity profiles, the planned use of two TKIs has never been investigated. We report on a phase 2 study that was designed to evaluate efficacy and safety of a treatment alternating nilotinib and imatinib, in newly diagnosed BCR-ABL1 positive, chronic phase, CML patients. One hundred twenty-three patients were enrolled. Median age was 56 years. The probabilities of achieving a complete cytogenetic response, a major molecular response, and a deep molecular response (MR 4.0) by 2 years were 93%, 87%, and 61%, respectively. The 5-year overall survival and progression-free survival were 89%. Response rates and survival are in the range of those reported with nilotinib alone. Moreover, we observed a relatively low rate of cardiovascular adverse events (5%). These data show that the different efficacy and toxicity profiles of TKIs could be favorably exploited by alternating their use. Am. J. Hematol. 91:617-622, 2016. © 2016 Wiley Periodicals, Inc.

    The recent National Institute for Health and Care Excellence (NICE) guideline on Fertility (2012) suggests that IVF should be offered to couples with unexplained subfertility after 2 years of expectant management. The evidence on which these recommendations are based is not robust and there is a lack of agreement among specialists regarding the management of unexplained subfertility. We conducted an online survey among fertility specialists to find out the general consensus regarding the management of these couples. An e-mail questionnaire was sent to 420 reproductive medicine clinicians and 136 (32.38%) replied. Only 16% said they would always recommend IVF as the first line management for these couples, irrespective of age and duration of infertility. Of those surveyed, 39% agreed to the new NICE proposal, 33% agreed partly and 25% did not agree at all. A total of 27% of the respondents said they would definitely change their practice according to the NICE proposal but 30% said they would not; 29% said they might change their policy while the rest were unsure. This survey confirms the ongoing clinical uncertainty among fertility specialists in managing couples with unexplained subfertility. PMID:25162601

    A blood clot or thrombus triggers the onset of most vascular diseases, like stroke or heart attack. Thrombolysis is the only treatment that can restore blood flow rapidly and easily. Unfortunately, the standard thrombolytic, tissue plasminogen activator (tPA), has proven inadequate and is being replaced by invasive endovascular procedures, which are time consuming and limited in their availability in relation to the scope of the problem. Historically, when tPA clinical trials began, it was not recognized sufficiently that without the other natural plasminogen activator, prourokinase (proUK), thrombolysis by tPA was seriously compromised. The reason is that the 2 activators have complementary mechanisms of action in fibrinolysis, making their combination a requirement for optimal efficacy and synergy. Biological fibrinolysis also uses both activators, explaining why such low endogenous concentrations are sufficient. A low-dose sequential combination of tPA and proUK was tested in acute myocardial infarction, where it was exceptionally effective and safe. Because native proUK at pharmacological doses was vulnerable to spontaneous conversion to urokinase, jeopardizing safety, a site-directed mutant was developed that improved proUK's plasma stability fivefold without interfering with its mode of action. Mini-bolus tPA followed by low-dose proUK infusion is a simple, safe, effective, and promising first-line treatment of acute thrombotic disorders. PMID:26714208

    Background Automated Mediace Treponema pallidum latex agglutination (TPLA) and Mediace rapid plasma reagin (RPR) assays are used by many laboratories for syphilis diagnosis. This study compared the results of the traditional syphilis screening algorithm and a reverse algorithm using automated Mediace RPR or Mediace TPLA as first-line screening assays in subjects undergoing a health checkup. Methods Samples from 24,681 persons were included in this study. We routinely performed Mediace RPR and Mediace TPLA simultaneously. Results were analyzed according to both the traditional algorithm and reverse algorithm. Samples with discordant results on the reverse algorithm (e.g., positive Mediace TPLA, negative Mediace RPR) were tested with Treponema pallidum particle agglutination (TPPA). Results Among the 24,681 samples, 30 (0.1%) were found positive by traditional screening, and 190 (0.8%) by reverse screening. The identified syphilis rate and overall false-positive rate according to the traditional algorithm were lower than those according to the reverse algorithm (0.07% and 0.05% vs. 0.64% and 0.13%, respectively). A total of 173 discordant samples were tested with TPPA by using the reverse algorithm, of which 140 (80.9%) were TPPA positive. Conclusions Despite the increased false-positive results in populations with a low prevalence of syphilis, the reverse algorithm detected 140 samples with treponemal antibody that went undetected by the traditional algorithm. The reverse algorithm using Mediace TPLA as a screening test is more sensitive for the detection of syphilis. PMID:26522755

  3. Colorectal stenting as first-line treatment in acute colonic obstruction

    Tumoral obstructions in almost the entire gastrointestinal tract can be resolved with interventional digestive endoscopy techniques. Self-expanding metal stent (SEMS) insertion in the obstructed colon is a minimally invasive and relatively simple procedure providing an effective first-line treatment for relief of acute malignant obstruction symptoms and serving either as a preoperative or “bridge to surgery” procedure or as palliative definitive care. This technique was introduced in the early 1990s. Although there is still debate about its real value, a lot of reports have been published since then and the procedure is advocated by many surgical groups as the method of choice for the initial treatment of left-sided tumoral colonic obstruction. Before the procedure, colonic obstruction has to be diagnosed by abdominal radiographs, water contrast enema and/or a computed tomography scan. The greatest information is provided by the latter and it is perhaps the method of choice prior to stenting. Skills and training are mandatory, as in all interventional procedures. The key step for success is to cross the malignant stricture with a guidewire. Care must be taken not to over insufflate an obstructed colon during the procedure. SEMS slide over the guidewire through the endoscope working channel or in parallel, outside the endoscope. An average 7% perforation rate has been reported during the procedure and other minor complications can appear in the follow up. However, as a whole, this technique seems to compare favorably with surgery. PMID:24147193

    While an increasing number of therapeutic options are now available for the first-line treatment of locally advanced or metastatic pancreatic cancer, the optimal choice for treatment in the second-line setting and beyond is less well defined. A variety of cytotoxic agents, either alone or in combination, have been evaluated, although primarily in the context of small single-arm or retrospective studies. Most regimens have been associated with median progression-free survival rates in the range of 2-4 mo and overall survival rates between 4-8 mo, highlighting the very poor prognosis of patients who are candidates for such treatment. Targeted therapies studied in this chemotherapy-refractory setting, meanwhile, have produced even worse efficacy results. In the current article, we review the clinical evidence for treatment of refractory disease, primarily in patients who have progressed on front-line gemcitabine-based chemotherapy. In the process, we highlight the limitations of the available data to date as well as some of the challenges in designing appropriate clinical trials in this salvage setting, including how to select an appropriate control arm given the absence of a well-established reference standard, and the importance of incorporating predictive biomarkers and quality of life measures whenever possible into study design.

    After description of the importance of EGFR mutations in non-small cell lung cancer and confirmation that tyrosine-kinase inhibitors are more beneficial than chemotherapy in patients with EGFR+ tumours, treatment with one of these drugs has become the standard recommendation. Despite this advance, patients continue to progress and consequently there is a need to search for alternative treatments. Some studies have analysed afatinib activity after first-generation TKI therapy, as well as its administration in combination with conventional chemotherapy. Afatinib produces significant response rates and progression-free survival times after the development of clinical resistance, which are independent of the presence of the T790M resistance mutation and can be attributed to continued pan-HER inhibition. In addition to the initial clinical trial, LUX-LUNG-1, data are available from the use of afatinib in routine clinical practice, within extended use programs. Overall, response rates of between 7 and 15% can be expected with a duration of approximately 24 months and a median progression-free time of about 4 months. A study combining afatinib with cetuximab has obtained a high response rate. Afatinib toxicity in second-line treatment is similar to that appears when the drug is used as first-line therapy (mainly mucocutaneous and diarrhoea) and can be managed with routine measures. In conclusion, afatinib should be considered as a treatment option in patients with EGFR mutations who show disease progression after a first tyrosine-kinase inhibitor. PMID:27426244

    The treatment of primary central nervous system lymphoma (PCNSL) has been considerably improved over recent years. In this article, we report six cases of PCNSL treated by first-line induction chemotherapy followed by intensive chemotherapy and autologous stem cell transplantation (ASCT). Six immunocompetent patients presenting with a PCNSL, confirmed by thoraco-abdomino-pelvic computer tomography scan and bone marrow biopsy, were treated with induction chemotherapy followed by BEAM intensive chemotherapy and ASCT and radiotherapy. At the end of the treatment, all the patients were in complete remission. After a median follow-up of 41.5 months (17-70 months), four patients were alive without signs of relapse (median survival: 35.5 months). Two patients died from relapse at 19 and 23 months. The neurotoxicity was low with epilepsy in one patient and persistent left side dysesthesia in another one. These results are fairly encouraging. Other studies with greater numbers of patients and longer follow-up are needed to confirm this study. PMID:16146534

  7. Pertuzumab: in the first-line treatment of HER2-positive metastatic breast cancer.

    The humanized monoclonal antibody pertuzumab is the first in a new class of drugs, the human epidermal growth factor receptor (HER) dimerization inhibitors. Given that pertuzumab binds to a different epitope of the HER2 extracellular domain than trastuzumab, combination therapy with pertuzumab plus trastuzumab may result in more comprehensive blockade of HER2 signalling than can be achieved with trastuzumab alone. The efficacy of adding pertuzumab to trastuzumab plus docetaxel for the first-line treatment of HER2-positive metastatic breast cancer was demonstrated in the randomized, double-blind, multinational, phase III CLEOPATRA trial. Both independently assessed progression-free survival (primary endpoint) and investigator-assessed progression-free survival were significantly improved in patients receiving pertuzumab plus trastuzumab and docetaxel compared with those receiving placebo plus trastuzumab and docetaxel. The prespecified interim analysis of survival revealed a strong trend towards a survival benefit associated with pertuzumab, although this was not considered statistically significant. The objective response rate was higher with pertuzumab than with placebo. Intravenous pertuzumab had an acceptable tolerability profile when added to trastuzumab and docetaxel in the CLEOPATRA trial.

    The advent of intracytoplasmic sperm injection (ICSI) has contributed to a significant growth in the delivery of assisted conception technique, such that IVF/ICSI procedures are now recommended over other interventions. Even the UK National Institute for Health Care Excellence (NICE) guidelines controversially recommends against intrauterine insemination (IUI) procedures in favour of IVF. We reflect on some of the clinical, economic, financial and ethical realities that have been used to selectively promote IVF over IUI, which is less intrusive and more patient friendly, obviates the need for embryo storage and has a global application. The evidence strongly favours IUI over IVF in selected couples and national funding strategies should include IUI treatment options. IUI, practised optimally as a first line treatment in up to six cycles, would also ease the pressures on public funds to allow the provision of up to three IVF cycles for couple who need it. Fertility clinics should also strive towards ISO15189 accreditation standards for basic semen diagnosis for male infertility used to triage ICSI treatment, to reduce the over-diagnosis of severe male factor infertility. Importantly, there is a need to develop global guidelines on inclusion policies for IVF/ICSI procedures. These suggestions are an ethically sound basis for constructing the provision of publicly funded fertility treatments. PMID:27076499

    Tuberculous sputum contains multiple Mycobacterium tuberculosis populations with different requirements for isolation in vitro. These include cells that form colonies on solid media (plateable M. tuberculosis), cells requiring standard liquid medium for growth (nonplateable M. tuberculosis), and cells requiring supplementation of liquid medium with culture supernatant (SN) for growth (SN-dependent M. tuberculosis). Here, we describe protocols for the cryopreservation and direct assessment of antimicrobial tolerance of these M. tuberculosis populations within sputum. Our results show that first-line drugs achieved only modest bactericidal effects on all three populations over 7 days (1 to 2.5 log10 reductions), and SN-dependent M. tuberculosis was more tolerant to streptomycin and isoniazid than the plateable and nonplateable M. tuberculosis strains. Susceptibility of plateable M. tuberculosis to bactericidal drugs was significantly increased after passage in vitro; thus, tolerance observed in the sputum samples from the population groups was likely associated with mycobacterial adaptation to the host environment at some time prior to expectoration. Our findings support the use of a simple ex vivo system for testing drug efficacies against mycobacteria that have phenotypically adapted during tuberculosis infection. PMID:26883695

    Treatment of metastatic castration-resistant prostate cancer (mCRPC) has been revolutionized in recent years. It is well known that androgen receptor is still active in most patients with disease progression and serum testosterone levels <50 ng/dL. Moreover, further hormonal maneuvers, either through decreasing androgen levels (abiraterone) or by targeting the androgen receptor (AR) pathway (enzalutamide), prolong survival. In addition, a new cytostatic able to overcome docetaxel resistance, cabazitaxel, and the radioisotope radium 223 have been incorporated to the armamentarium of mCRPC. mCRPC is not only a heterogeneous tumor, it changes over time developing neuroendocrine features or selection of clones resistant to hormonal maneuvers. In addition, the multiplicity of current treatments, make it necessary to design algorithms that help the specialist to choose the most appropriate treatment for a particular patient. The lack of randomized trials comparing face to face the different available options limit the scope of this review. In this article, the authors describe the prognostic factors for first line therapy in patients with mCRPC, and propose a treatment algorithm for mCRPC based on the levels of scientific evidence available and, if not available, on the consensus between medical professionals. Finally, the panel discuss how to define progressive disease in the setting of mCRPC and treatment with targeted therapies. PMID:26363809

    There is an ongoing need for development of new chemotherapeutic regimens for metastatic breast cancer [mBC], especially when tumors lack therapeutic targets such as the estrogen or progesterone receptor [ER/PR], or the human epidermal growth factor receptor-2 [HER2]. Capecitabine is an orally bioavailable fluoropyrimidine approved for monotherapy in mBC, and bevacizumab is a monoclonal antibody targeting vascular endothelial growth factor which has shown to be active in mBC and tolerable in combination with other chemotherapeutics. The combination of these two agents has been explored in multiple phase II and III clinical studies, with improvements in progression-free survival and overall response rates noted as compared to capecitabine monotherapy. However, the use of bevacizumab in combination with capecitabine and other chemotherapy agents for mBC remains beset with controversy due to safety concerns, cost issues, and pending regulatory decisions.

    Objective Using disease-modifying antirheumatic drugs (DMARDs) improves outcomes in rheumatoid arthritis (RA) and is a nationally endorsed quality measure. We investigated the prevalence and predictors of receiving glucocorticoids alone for the treatment of RA in a nationwide sample of Medicare beneficiaries. Methods Among individuals ages ≥65 years with RA enrolled in the Part D prescription drug benefit in 2009, we compared those with ≥1 DMARD claim to those receiving glucocorticoid monotherapy, defined as no DMARD claim and an annual glucocorticoid supply of ≥180 days or an annual dose of ≥900 mg of prednisone or equivalent. We fit multivariable models to determine the sociodemographic and clinical factors associated with glucocorticoid monotherapy. Results Of 8,125 beneficiaries treated for RA, 10.2% (n = 825) received glucocorticoids alone. Beneficiaries with low incomes were more likely to receive glucocorticoids alone (12.3%; 95% confidence interval [95% CI] 10.9–13.8% versus 9.4%; 95% CI 8.6–10.1%), as were those living in certain US regions. More physician office visits and hospitalizations were associated with glucocorticoid monotherapy. Individuals who had no contact with a rheumatologist were significantly more likely to receive glucocorticoids alone (17.5%; 95% CI 16.0–19.0% versus 8.5%; 95% CI 7.4–9.5% for those with no rheumatology visits versus 1–4 visits). Conclusion Approximately 1 in 10 Medicare beneficiaries treated for RA received glucocorticoids without DMARDs in 2009. Compared to DMARD users, glucocorticoid users were older, had lower incomes, were more likely to live in certain US regions, and were less likely to have seen a rheumatologist, suggesting persistent gaps in quality of care despite expanded drug coverage under Part D.

    Background Wilson’s disease (WD) evolves rapidly and is fatal if untreated. The treatment of WD patients with mild liver disease is not clearly defined. To address this issue, we evaluated long-term outcomes of three treatment regimens (D-penicillamine, zinc or both) in patients diagnosed in childhood. Methods We retrospectively evaluated efficacy, compliance and reasons for treatment discontinuation in 42 WD patients (median age at diagnosis: 6 years; median follow-up: 12 years) with mild liver disease. Treatment duration for each treatment block until a medication change or completion of follow-up was analyzed. Events of change of treatment were evaluated using Kaplan-Meier analysis. Results Total discontinuations due to treatment failure or adverse events were more frequent in patients receiving D-penicillamine (45%) or combination (36%) therapy than in patients receiving zinc (12%) (P = .001 and P = .02, respectively). Treatment failure was more frequent on D-penicillamine (28%) and combination therapy (36%) than on zinc (12%); the difference was statistically significant only between zinc and combination therapy (P = .03). First-line zinc monotherapy controlled WD-related liver disease in 13/15 patients (87%); the two subjects that failed on zinc were poor adherent. Zinc was effective in 3/5 (60%) patients that failed on D-penicillamine and combination regimens. All 15 D-penicillamine responders that switched to zinc had good control of liver disease at a median follow-up of 13.1 years. Among 6 D-penicillamine non-responders that switched to zinc, 4 (67%) responded. At follow-up completion, only 5/42 (12%) patients failed. Adverse event-induced discontinuation was significantly more frequent in patients on D-penicillamine than in patients receiving zinc (P = .03). Conclusions Zinc monotherapy is effective in controlling WD-related liver disease both as first-line and as maintenance treatment in patients with mild liver disease diagnosed in

    Managing patients with bipolar disorder remains a challenge due to its chronic nature. In addition, bipolar depression remains understudied even though patients spend more time in depressive episodes than in manic ones. Effective treatment requires an accurate and timely diagnosis, psychoeducation, psychotherapy, pharmacotherapy, and implementation of elements of the chronic care model. Pharmacologic strategies for treating bipolar depression differ from those for bipolar mania as well as those for unipolar depression and require knowledge of the efficacy and safety of agents including mood stabilizers, atypical antipsychotics, and antidepressants both as monotherapy and in combination.

    Amphibian populations worldwide are currently experiencing unprecedented declines due to the combined effects of emerging infectious disease and climate change. The skin is the first line of defence in preventing establishment of pathogens and associated infections. Although amphibians undergo regular sloughing of the outer layer of the skin, the potential for regular sloughing to play a role in influencing cutaneous microbial populations and pathogens has been largely overlooked. In the present study, we assessed the effect of skin sloughing on cultivable cutaneous bacterial abundance in the green tree frog (Litoria caerulea). We also examined the effects of temperature and hydric environment on sloughing frequency and microbial re-establishment rates. Our data showed that cultivable cutaneous bacterial abundance was significantly reduced by sloughing events, and frogs kept at ‘summer’ temperatures (23–33°C) sloughed almost twice as frequently as those maintained at ‘winter’ temperatures (13–23°C). No effect of hydric environment on sloughing frequency was observed, but we did find that sloughing in L. caerulea appeared to be linked to ambient light cycles. Examination of the effect of sloughing on microbial recolonization indicated that at cool temperatures, an extended intermoult interval allowed microbial abundance to reach higher levels than at warmer ‘summer’ temperatures (when the intermoult interval was significantly reduced). Our data suggest that sloughing may significantly influence the establishment and/or maintenance of cutaneous bacterial populations (pathogenic, mutualistic and/or commensal) and this, in turn, may be affected by environmental factors, such as ambient light and temperature. These findings are likely to be important for our understanding of the ecology of skin-based pathogens, such as the amphibian chytrid fungus, Batrachochytrium dendrobatidis. PMID:27293633

    The purpose of this study was to carry out drug-drug compatibility studies on pure first line anti-tuberculosis drugs, viz., rifampicin (R), isoniazid (H), pyrazinamide (Z), and ethambutol hydrochloride (E). Various possible binary, ternary, and quaternary combinations of the four drugs were subjected to accelerated stability test conditions of 40 degrees C and 75% relative humidity (RH) for 3 months. For comparison, parallel studies were also conducted on single drugs. Changes were looked for in the samples drawn after 15, 30, 60, and 90 days of storage. Analyses for R, H, and Z were carried out using a validated HPLC method. The E was analyzed by liquid chromatography-tandem mass spectrometry (LC-MS/MS), as it does not absorb in ultraviolet (UV). All single pure drugs were relatively stable and showed only 3%-5% degradation under accelerated conditions for 3 months. However, significant interactions were observed in case of the drug mixtures. In particular, ternary and quaternary drug combinations containing R and H along with Z and/or E were very unstable, showing 90%-95% and 70%-75% loss of R and H, respectively. In all these cases, isonicotinyl hydrazone (HYD) of 3-formylrifamycin and H was found to be the major degradation product. In case of RE and RZE mixtures, where H was absent, 3-formylrifamycin was instead the key degradation product. Another unidentified peak was observed in the mixture containing RZE. Apart from these chemical changes, considerable physical changes were also observed in pure E and the mixtures containing E, viz., RE, ZE, RHE, RZE, and RHZE. In addition, significant physical changes associated with noteworthy loss of H and E were also observed in mixtures containing HE and HZE. The present study thus amply shows that the four primary anti-tuberculosis drugs, when present together, interact with each other in a multiple and complex manner. PMID:16370181

    Fosfomycin is a new agent to Canada approved for the treatment of acute uncomplicated cystitis (AUC) in adult women infected with susceptible isolates of E. coli and Enterococcus faecalis. We reviewed the literature regarding the use of oral fosfomycin for the treatment of AUC. All English-language references from 1975 to October 2015 were reviewed. In Canada, fosfomycin tromethamine is manufactured as Monurol® and is available as a 3-gram single dose sachet. Fosfomycin has a unique chemical structure, inhibiting peptidoglycan synthesis at an earlier site compared to β-lactams with no cross-resistance with other agents. Fosfomycin displays broad-spectrum activity against ESBL-producing, AmpC-producing, carbapenem-non-susceptible, and multidrug-resistant (MDR) E. coli. Resistance to fosfomycin in E. coli is rare (<1%). Fosfomycin is excreted unchanged in the urine by glomerular filtration with peak urinary concentration ~4000 µg/mL and remains at concentrations >100 µg/mL for 48 hours after a single 3-gram oral dose. No dosage adjustments are required in elderly patients, in pregnant patients, or in either renal or hepatic impairment. Fosfomycin demonstrates a favorable safety profile, and clinical trials have demonstrated efficacy in AUC that is comparable to ciprofloxacin, nitrofurantoin, and trimethoprim-sulfamethoxazole. Fosfomycin's in vitro activity against common uropathogens, including MDR isolates, its favorable safety profile including pregnancy patients, drug interactions, and clinical trials data demonstrating efficacy in AUC, has resulted in Canadian, US, and European guidelines/authorities recommending fosfomycin as a first line agent for the treatment of AUC.

    Background Treatment for tuberculosis (TB) is common among individuals receiving stavudine-containing highly active antiretroviral therapy (HAART), but the effect of TB treatment on stavudine toxicity has received little attention. We estimated the effect of TB treatment on risk of stavudine substitution among individuals receiving first-line HAART. Methods We evaluated a cohort of 7,066 patients who initiated HAART between April 2004 and March 2007 in Johannesburg, South Africa. Three exposure categories were considered: ongoing TB treatment at HAART initiation; concurrent initiation of TB treatment and HAART; incident TB treatment after HAART initiation. The outcome was single-drug stavudine substitution. Adjusted hazard ratios (aHRs) were estimated using marginal structural models to control for confounding, loss to follow-up, and competing risks. Results Individuals with ongoing and concurrent TB treatment were at increased risk of stavudine substitution, irrespective of stavudine dose. For ongoing TB treatment, aHR was 3.18 (95% confidence interval [CI] 1.82-5.56) in the first two months of HAART, 2.51 (95% CI 1.77-3.54) in months 3-6, and 1.19 (95% CI 0.94-1.52) thereafter. For concurrent TB treatment, aHR was 6.60 (95% CI 3.03-14.37) in the first two months,1.88 (95% CI 0.87-4.09) in months 3-6, and 1.07 (95% CI 0.65-1.76) thereafter. There was no effect of incident TB on stavudine substitution risk. Conclusions Risk of stavudine substitution was increased among patients receiving TB treatment, especially soon after HAART initiation. In settings where alternative antiretroviral drugs are available, initiation of stavudine in patients receiving TB treatment may need to be reconsidered. PMID:19385733

    There is no standard for second-line chemotherapy in poorly differentiated grade 3 neuroendocrine carcinoma (G3-NEC) patients. We analyzed the antitumor efficacy of 5-fluorouracil and oxaliplatin (FOLFOX) chemotherapy in this population. A single-center retrospective analysis of consecutive G3-NEC patients treated with FOLFOX chemotherapy after failure of a cisplatinum-based regimen between December 2003 and June 2012 was performed. Progression-free survival (PFS), overall survival (OS), response rate, and safety were assessed according to RECIST 1.1 and NCI.CTC v4 criteria. Twenty consecutive patients were included (seven males and 13 females; median age 55; range 23-87 years) with a performance status of 0-1 in 75% of them. Primary location was gastroenteropancreatic in 12, thoracic in four, other in two, and unknown in two patients. There were 12 (65%) large-cell and 7 (30%) small-cell G3-NEC tumors, and 1 (5%) unknown. All patients had distant metastases. Twelve (60%) patients received FOLFOX as second-line treatment and 8 (40%) as third-line treatment or later and the median number of administered cycles was 6 (range 3-14). The median follow-up was 19 months. Median PFS was 4.5 months. Among the 17 evaluable patients, five partial responses (29%), six stable diseases (35%), and six progressive diseases (35%) were observed. Median OS was 9.9 months. Main Grade 3-4 toxicities were neutropenia (35%), thrombopenia (20%), nausea/vomiting (10%), anemia (10%), and elevated liver transaminases (10%). Our results indicate that the FOLFOX regimen could be considered as a second-line option in poorly differentiated G3-NEC patients after cisplatinum-based first-line treatment but warrant further confirmation in future larger prospective studies.

    Fosfomycin is a new agent to Canada approved for the treatment of acute uncomplicated cystitis (AUC) in adult women infected with susceptible isolates of E. coli and Enterococcus faecalis. We reviewed the literature regarding the use of oral fosfomycin for the treatment of AUC. All English-language references from 1975 to October 2015 were reviewed. In Canada, fosfomycin tromethamine is manufactured as Monurol® and is available as a 3-gram single dose sachet. Fosfomycin has a unique chemical structure, inhibiting peptidoglycan synthesis at an earlier site compared to β-lactams with no cross-resistance with other agents. Fosfomycin displays broad-spectrum activity against ESBL-producing, AmpC-producing, carbapenem-non-susceptible, and multidrug-resistant (MDR) E. coli. Resistance to fosfomycin in E. coli is rare (<1%). Fosfomycin is excreted unchanged in the urine by glomerular filtration with peak urinary concentration ~4000 µg/mL and remains at concentrations >100 µg/mL for 48 hours after a single 3-gram oral dose. No dosage adjustments are required in elderly patients, in pregnant patients, or in either renal or hepatic impairment. Fosfomycin demonstrates a favorable safety profile, and clinical trials have demonstrated efficacy in AUC that is comparable to ciprofloxacin, nitrofurantoin, and trimethoprim-sulfamethoxazole. Fosfomycin's in vitro activity against common uropathogens, including MDR isolates, its favorable safety profile including pregnancy patients, drug interactions, and clinical trials data demonstrating efficacy in AUC, has resulted in Canadian, US, and European guidelines/authorities recommending fosfomycin as a first line agent for the treatment of AUC.

    Background This is an update of a Cochrane review that was first published in Issue 1, 2009. Gestational trophoblastic neoplasia (GTN) is a rare but curable disease arising in the fetal chorion during pregnancy. Most women with low-risk GTN will be cured by evacuation of the uterus with or without single-agent chemotherapy. However, chemotherapy regimens vary between treatment centres worldwide and the comparable benefits and risks of these different regimens are unclear. Objectives To determine the efficacy and safety of first-line chemotherapy in the treatment of low-risk GTN. Search methods In September 2008, we electronically searched the Cochrane Gynaecological Cancer Group Specialised Register, the Cochrane Central Register of Controlled Trials (CENTRAL Issue 3, 2008), MEDLINE and EMBASE. In addition, we searched online trial registers, conference proceedings and reference lists of identified studies. We re-ran these searches in February 2012 for this updated review. Selection criteria For the original review, we included randomised controlled trials (RCTs), quasi-RCTs and non-RCTs that compared first-line chemotherapy for the treatment of low-risk GTN. For this updated version of the review, we included only RCTs. Data collection and analysis Two review authors independently assessed studies for inclusion and extracted data to a pre-designed data extraction form. Meta-analysis was performed by pooling the risk ratio (RR) of individual trials. Main results We included five moderate to high quality RCTs (517 women) in the updated review. These studies all compared methotrexate with dactinomycin. Three studies compared weekly intramuscular (IM) methotrexate with bi-weekly pulsed intravenous (IV) dactinomycin (393 women), one study compared five-day IM methotrexate with bi-weekly pulsed IV dactinomycin (75 women) and one study compared eight-day IM methotrexate-folinic acid (MTX-FA) with five-day IV dactinomycin (49 women). Overall, dactinomycin was associated

    Neisseria gonorrhoeae has developed resistance to most of the available therapeutic antimicrobials. The susceptibility to extended-spectrum cephalosporins, the last remaining first-line treatment option, is decreasing globally. This report describes the first two cases outside Japan of verified gonorrhoea clinical failures using internationally recommended first-line cefixime treatment. Enhanced awareness and more frequent follow-up examination, test-of-cure and appropriate verification/falsification of presumed clinical treatment failures, involving several clinical and laboratory parameters should be strongly emphasised worldwide.

    Abstract Background: There are limited data on primary human immunodeficiency virus drug resistance (HIVDR) in pediatric populations. This study aimed to assess the prevalence of primary HIVDR and associated risk factors among children initiating first-line antiretroviral therapy (ART) in Uganda. Methods: At three Ugandan clinics, children (age <12 years) requiring ART were recruited between January 2010 and August 2011. Before starting ART, blood was collected for viral load and pol gene sequencing. Drug resistance mutations were determined using the 2010 International AIDS Society–USA mutation list. Risk factors for HIVDR were assessed with multivariate regression analysis. Results: Three hundred nineteen HIV-infected children with a median age of 4.9 years were enrolled. Sequencing was successful in 279 children (87.5%). HIVDR was present in 10% of all children and 15.2% of children <3 years. Nucleoside reverse transcriptase inhibitors (NRTIs), non-NRTI (NNRTI), and dual-class resistance was present in 5.7%, 7.5%, and 3.2%, respectively. HIVDR occurred in 35.7% of prevention of mother-to-child transmission (PMTCT)–exposed children, 15.6% in children with unknown PMTCT history, and 7.7% among antiretroviral-naive children. History of PMTCT exposure [adjusted odds ratio (AOR): 2.6, 95% CI: 1.3–5.1] or unknown PMTCT status (AOR: 3.8, 95% CI: 1.1–13.5), low CD4 (AOR: 2.2, 95% CI: 1.3–3.6), current breastfeeding (AOR: 7.4, 95% CI: 2.6–21), and current maternal ART use (AOR: 6.4, 95% CI: 3.4–11.9) emerged as risk factors for primary HIVDR in multivariate analysis. Conclusion: Pretreatment HIVDR is high, especially in children with PMTCT exposure. Protease inhibitor (PI)–based regimens are advocated by the World Health Organization, but availability in children is limited. Children with (unknown) PMTCT exposure, low CD4 count, current breastfeeding, or maternal ART need to be prioritized to receive PI-based regimens. PMID:26723018

    Introduction We compared the effectiveness of tenofovir/emtricitabine (TDF/FTC) combined with either lopinavir/r (LPV/r) or another recommended third drug in the 2010 French guidelines in antiretroviral-naïve patients starting combination antiretroviral therapy in 2004–2008 in the French Hospital Database on HIV. Methods The outcomes were stop or switch of the third component, viral load (VL) <500 copies/ml, an increase of at least 100 CD4 cells/mm3, AIDS-defining event and non-AIDS-defining hospitalization or death. Propensity scores were estimated by logistic regression based on the clinical centre and other confounders. In each clinical centre, each patient initiating LPV/r was matched with a patient initiating another third drug (efavirenz or atazanavir/r) and having a close propensity score. Cox's proportional hazards models were then used, with treatment as covariate. Time was right-censored at four years. Results 1269 patients started LPV/r plus TDF/FTC, and 890 could be matched to 890 patients receiving another third drug. Baseline characteristics were well balanced between these two groups. LPV/r was associated with a higher risk of third drug stop (hazard ratio (HR): 1.69; 95% confidence interval (CI), 1.42–2.00) and with less rapid viral suppression (HR: 0.83; 95% CI, 0.72–0.95). There was no difference in the time required for a CD4 cell increment of at least 100/mm3, or to the occurrence of an AIDS-defining event. Non-AIDS-defining hospitalizations or deaths were more frequent with LPV/r (HR: 1.79; 95% CI, 1.33–2.39). Conclusions For first-line therapy, in this observational setting, TDF/FTC plus LPV/r were less durable than TDF/FTC plus another recommended third drug, led to a less rapid viral suppression and were associated with a higher risk of non-AIDS morbidity.

    AIM: To confirm the efficacy and safety of bevacizumab/XELOX combination for the treatment of locally advanced or metastatic colorectal cancer (CRC) in Italy. METHODS: This multicentric, prospective, open-label study included patients with CRC previously untreated with chemotherapy. Patients were administered bevacizumab in combination with XELOX. The primary efficacy end-point was progression-free survival (PFS). Secondary end-points included time to overall response (TOR), duration of response (DOR), time to treatment failure (TTF) and overall survival (OS). The incidence and type of adverse events AEs and severe AEs were evaluated. Also, the mutational status of BRAF and KRAS was assessed by high resolution melting and direct sequencing, and quality of life (QoL) was measured by the EuroQoL EQ-5D questionnaire at baseline and at the last visit. RESULTS: The intention-to-treat population included 197 patients (mean age: 62.3 ± 9.9 years, 56.4% males). At baseline, 16/34 evaluable subjects (47.1%) harbored a KRAS and/or a BRAF mutation; the mean QoL index was 80.2 ± 14.3. First-line therapy was given for 223.7 ± 175.9 d, and after a mean follow-up of 387.7 ± 238.8 d all patients discontinued from the study mainly for disease progression (PD, 45.4%) and AEs (25.4%). Median PFS was 9.7 mo (95%CI: 8.4-10.5) and the median values for secondary end-points were: TOR = 3.9 mo (95%CI: 2.6-4.7), DOR = 8.5 mo (95%CI: 7.3-10.3), TTF = 6.7 mo (95%CI: 6.0-7.7) and OS = 23.2 mo (95%CI: 20.1-27.2). Patients carrying at least one lesion had a lower overall response rate (66.7% vs 88.9%) and a lower probability of achieving complete or partial response than those without mutations, but the difference in relative risk was not statistically significant (P = 0.2). Mean EQ-5D-3L raw index score significantly decreased to 74.9 ± 19.1 at the last visit (signed-rank test, P = 0.0076), but in general the evaluation on QoL perceived by patients was good. CONCLUSION: The efficacy of

    Opinion statement: The optimal initial treatment of follicular lymphoma (FL) is not known, and initial management of patients varies considerably between providers and institutions. The assertion that patients with low tumor burden can be observed for a period of time is being challenged owing to the safety and tolerability of novel therapeutics and the movement of the field away from traditional chemotherapy agents. Single agent rituximab has become increasingly popular as initial management of patients with low tumor burden disease, and there is evidence that prolonged treatment with rituximab can improve progression-free survival (PFS) when compared to induction with rituximab or observation. Radioimmunotherapy (RIT) has similarly shown efficacy in low tumor burden disease. Novel agents such as lenalidomide, idelalisib, and ibrutinib are being studied in the first-line setting. Importantly, none of these strategies have demonstrated an improved overall survival in a randomized study versus observation. It is the opinion of the authors that endpoints such as PFS alone, while important, should not drive changes in management with limited resources. Composite endpoints including quality of life are more informative on the true impact of treatments on patients with follicular lymphoma. Providers should encourage all patients to be treated in the context of an appropriate clinical trial when possible. If a patient is not a clinical trial candidate, we typically treat patients with advanced stage and high tumor burden with chemoimmunotherapy. The decision to give maintenance rituximab is individualized to the patient, as there is no overall survival benefit. In patients with early stage disease, we favor consideration of radiation therapy if the patient is a candidate. Our initial recommendation to patients with advanced stage, low tumor burden disease, is close observation or "watch and wait." We have observed that most patients become comfortable over time with an

    Background Conservative approach for complicated appendicitis has been gradually adopted in children to decrease postoperative morbidity. The first aim of this study was to assess the efficacy of a second-line antibiotics enlarged on Pseudomonas aeruginosa and Enterococcus in case of poor clinical outcome after initial conservative approach for appendiceal mass and abscess. The second aim of this study was to identify predictive factors of failure of first-line antibiotics. Methods We performed a prospective review of all the cases of appendiceal mass or abscess managed at our institution between November 2007 and September 2011 after implementation of a conservative protocol including a second-line antibiotics in case of poor initial clinical outcome. Results A total of 64 consecutive patients were included. We observed a success in 46 patients after the first-line antibiotics and in 14 of the remaining patients after the second-line. The only predictive factor of failure of the first-line antibiotics was a shorter duration of symptoms before admission (p = 0.02). Laparoscopic appendectomy was performed in all the cases (emergency or interval procedure) with six postoperative complications and two conversions to open surgery. Conclusions A gradual adapted antibiotherapy in nonoperative management of appendiceal abscess and mass is effective. We found no relevant predictive factor of failure of the first-line antibiotics.

    Objectives Major protease mutations are rarely observed following first-line failure with PIs and interpretation of genotyping results in this context may be difficult. We performed extensive phenotyping of viruses from five patients failing lopinavir/ritonavir monotherapy in the MONARK study without major PI mutations by standard genotyping. Methods Phenotypic susceptibility testing and viral infectivity assessments were performed using a single-cycle assay and fold changes (FC) relative to a lopinavir-susceptible reference strain were calculated. Results >10-fold reduced baseline susceptibility to lopinavir occurred in two of five patients and >5-fold in another two. Four of five patients exhibited phylogenetic evidence of a limited viral evolution between baseline and failure, with amino acid changes at drug resistance-associated positions in one: T81A emerged in Gag with M36I in the protease gene, correlating with a reduction in lopinavir susceptibility from FC 7 (95% CI 6–8.35) to FC 13 (95% CI 8.11–17.8). Reductions in darunavir susceptibility (>5 FC) occurred in three individuals. Discussion This study suggests both baseline reduced susceptibility and evolution of resistance could be contributing factors to PI failure, despite the absence of classical PI resistance mutations by standard testing methods. Use of phenotyping also reveals lower darunavir susceptibility, warranting further study as this agent is commonly used following lopinavir failure. PMID:25096075

    Objectives Previous studies have demonstrated gaps in achievement of low-density lipoprotein-cholesterol (LDL-C) goals among patients at very high cardiovascular risk. We aimed to investigate lipid treatment patterns, rates and predictors of lipid targets attainment, in such outpatients in an urban area of Greece. Methods This was a prospective observational study, conducted in 19 outpatient clinics of Western Greece. We recruited patients with established cardiovascular disease (CVD) and/or diabetes mellitus (DM), previously (at least 3 months before baseline assessment) untreated with any lipid lowering medication. Lipid profile assessment was performed at baseline (prior to lipid-lowering treatment initiation) and at follow-up. Lipid lowering treatment choice was at physicians’ discretion and was kept constant until follow-up. Results We recruited 712 patients with a mean age 61.4 ± 10.4 years, 68.0% males, 43.0% with DM, 64.7% with prior coronary artery disease-CAD. In total, 237/712 (33.3%) of prescribed regimens were of high or very high LDL-C lowering efficacy and out of them 113/237 (47.7%) comprised a combination of statin and ezetimibe. At follow-up the primary target of LDL-C < 70 mg/dL (1.8 mmol/L) was achieved in 71(10.0%) patients. The secondary target of non-HDL-C < 100 mg/dL (2.6 mmol/L) in the subgroup of patients with DM or increased triglycerides levels (>150 mg/dl or 1.7 mmol/L) was achieved in 45(11.6%) of patients. In multivariate logistic regression analysis (AUC = 0.71, 95% CIs 0.65-0.77, p < 0.001) male gender, smoking, baseline LDL-C and very high potency LDL-C lowering regimen emerged as independent predictors of LDL-C goal attainment (OR = 1.88, 95% CIs 1.03-3.44, p = 0.04, OR = 0.57, 95% CIs 0.33-0.96, p = 0.04, OR = 0.98, 95% CIs 0.98-0.99, p < 0.001 and OR = 2.21, 95% CIs 1.15-4.24, p = 0.02 respectively).

    Introduction. The objective of this study was to investigate clinical effectiveness and incremental lifetime costs associated with first-line bevacizumab in older patients with metastatic colorectal cancer (mCRC). Methods. Patients diagnosed with mCRC in 2004–2007 were identified from the Surveillance, Epidemiology, and End Results-Medicare database and stratified by first-line treatment (no chemotherapy [CTx], CTx alone, CTx plus bevacizumab). The impact of first-line bevacizumab on survival was investigated using a propensity score adjusted multivariate Cox proportional hazards model. Mean lifetime costs for each cohort were calculated using Medicare claims for all services rendered between diagnosis and end of follow-up, adjusting for death and censoring. Results. A total of 4,414 patients (mean age: 77.3 years) were identified, of whom 15% received first-line bevacizumab. Among first-line-treated patients, bevacizumab receipt was associated with improved overall survival (hazard ratio: 0.85 [95% confidence interval: 0.75–0.97]; p = .013), and this benefit was limited to patients who received >1 month of bevacizumab therapy. Median and mean survival were greatest in patients treated with CTx plus bevacizumab relative to CTx alone (CTx plus bevacizumab median 19.4 months [mean 28.0 months] vs. CTx alone median 15.1 months [mean 22.9 months]; p < .001), as were mean lifetime costs (mean per patient cost $143,284 vs. $111,280). Compared with CTx alone, CTx plus bevacizumab was associated with a 5.1-month increase in mean survival and a $32,004 increase in mean lifetime treatment costs, with an incremental cost of $75,303 per life-year gained. Conclusion. Bevacizumab use is associated with longer survival than CTx alone in older patients treated in real-world clinical settings, at an incremental cost of $75,303 per life-year gained.

    Purpose Several randomized trials investigating the preferable first-line combination chemotherapy regimen for metastatic colorectal cancer have shown inconsistent findings. Because a substantial number of patients are still being treated with “chemo-only” first-line therapies without targeted agents, we compared overall survival (OS) of patients treated in routine practice with oxaliplatin–fluoropyrimidine and irinotecan–fluoropyrimidine. Patients and methods Using the database of the Tumor Registry Colorectal Cancer, we identified 605 patients with metastatic colorectal cancer who received first-line fluoropyrimidine combination chemotherapy with either oxaliplatin (n=430) or irinotecan (n=175). The Tumor Registry Colorectal Cancer is a cohort study that prospectively documents treatment of colorectal cancer by office-based medical oncologists in Germany and has recruited over 5,000 patients. OS was estimated using the Kaplan–Meier method, and a multivariate Cox proportional hazard model was used to adjust for potentially confounding variables. Results Median OS was 26.8 (95% confidence interval [CI] 22.4–31.9) months with an oxaliplatin–fluoropyrimidine combination and 18.3 (95% CI 15.1–23.2) months with irinotecan–fluoropyrimidine first-line “chemo-only” therapy. Median progression-free survival was 9.0 (8.1–10.2) and 7.9 (7.2–10.2) months, respectively. The difference in OS was confirmed if analysis was restricted to patients with synchronous metastases (no prior treatment). Among other variables, proportion of patients receiving any second-line therapy did not differ between groups. Oxaliplatin-based first-line therapy was associated with improved OS in multivariate analysis adjusted for potentially confounding variables (hazard ratio 0.678, 95% CI 0.510–0.901, P=0.007). Conclusion In clinical routine practice, first-line treatment with oxaliplatin–fluoropyrimidine combination chemotherapy compared to irinotecan

    The case was a female in her early 80's. Due to abdominal bloating and lower limb edema, she visited a nearby doctor, was diagnosed to have nephrotic syndrome, and then was referred to our department. Upon initial consultation, TP of 4.1 g/dl, Alb of 1.7 g/dl, UN of 73 mg/dl, and Cr of 1.43 mg/dl, along with pleural effusion were observed by chest X-ray. A renal biopsy was not performed because permission could not be obtained. Despite the fact that management of the edema was performed using diuretic agents and albumin preparations, a reduced renal function and deterioration of the fluid retention were gradually observed. She originally displayed lower back pain and digestive symptoms and, therefore, cyclosporine monotherapy was initiated in order to address concerns of side effects such as osteoporosis and peptic ulcer due to adrenocortical steroid drugs (hereinafter abbreviated as steroid). Subsequently, hemodialysis was temporarily required but reduced urine protein and an improved renal function were gradually observed and she eventually achieved a complete remission. The possibility of a spontaneous remission of membranous nephropathy, etc. was considered, but a relapse occurred when the amount of cyclosporine was reduced. Thereafter, a complete remission was obtained with an increased dosage. As a result, the effectiveness of cyclosporine was thus confirmed. In treating nephrotic syndrome, steroid therapy is commonly performed and it is common for cyclosporine to be limited to steroid-resistant cases and/or steroid-dependent cases. However, it is believed that monotherapy could also be an option in cases in which the use of steroids is difficult, such as in cases of elderly patients. PMID:21116092

    Objective To determine the prevalence of JC virus (JCV) reactivation and JCV-specific cellular immune response during prolonged natalizumab treatment for multiple sclerosis (MS). Methods We enrolled 43 JCV-seropositive MS patients, including 32 on natalizumab monotherapy>18 months, 6 on interferon β-1a monotherapy>36 months and 5 untreated controls. We performed QPCR in cerebrospinal fluid (CSF), blood and urine for JCV DNA and we determined JCV-specific T cell responses using enzyme-linked immunosorbent spot (ELISpot) and intracellular cytokine staining (ICS) assays, ex vivo and after in vitro stimulation with JCV peptides. Results JCV DNA was detected in the CSF of 2/27 (7.4%) natalizumab-treated MS patients who had no symptoms or MRI lesions consistent with progressive multifocal leukoencephalopathy. JCV DNA was detected in blood of 12/43 (27.9%) and in urine of 11/43 (25.6%) subjects without difference between natalizumab-treated patients and controls. JC viral load was higher in CD34+ cells and in monocytes compared to other subpopulations. ICS was more sensitive than ELISpot, and JCV-specific T cell responses, mediated by both CD4+ and CD8+ T-lymphocytes, were detected more frequently after in vitro stimulation. JCV-specific CD4+ T-cells were detected ex vivo more frequently in MS patients with JCV DNA in CD34+ (p=0.05) and B cells (p=0.03). Interpretation Asymptomatic JCV reactivation may occur in CSF of natalizumab-treated MS patients. JCV DNA load is higher in circulating CD34+ cells and monocytes compared to other mononuclear cells, and JCV in blood might trigger a JCV-specific CD4+ T-cell response. JCV-specific cellular immune response is highly prevalent in all JCV-seropositive MS patients, regardless of treatment. PMID:24687904

    Objective To evaluate and compare long-term effectiveness of five antiepileptic drugs (AEDs) for monotherapy of adult patients with focal epilepsy in routine clinical practice. Methods Adult patients with focal epilepsy, who were prescribed with carbamazepine (CBZ), valproate (VPA), lamotrigine (LTG), topiramate (TPM), or oxcarbazepine (OXC) as monotherapy, during the period from January 2004 to June 2012 registered in Wenzhou Epilepsy Follow Up Registry Database (WEFURD), were included in the study. Prospective long-term follow-up was conducted until June 2013. The endpoints were time to treatment failure, time to seizure remission, and time to first seizure. Results This study included 654 patients: CBZ (n=125), VPA (n=151), LTG (n=135), TPM (n=76), and OXC (n=167). The retention rates of CBZ, VPA, LTG, TPM, and OXC at the third year were 36.1%, 32.4%, 57.6%, 37.9%, and 41.8%, respectively. For time to treatment failure, LTG was significantly better than CBZ and VPA (LTG vs. CBZ, hazard ratio, [HR] 0.80 [95% confidence interval: 0.67-0.96], LTG vs. VPA, 0.53 [0.37-0.74]); TPM was worse than LTG (TPM vs. LTG, 1.77 [1.15-2.74]), and OXC was better than VPA (0.86 [0.78-0.96]). After initial target doses, the seizure remission rates of CBZ, VPA, LTG, TPM, and OXC were 63.0%, 77.0%, 83.6%, 67.9%, and 75.3%, respectively. LTG was significantly better than CBZ (1.44 [1.15-1.82]) and OXC (LTG vs. OXC, 0.76 [0.63-0.93]); OXC was less effective than LTG in preventing the first seizure (1.20 [1.02-1.40]). Conclusion LTG was the best, OXC was better than VPA only, while VPA was the worst. The others were equivalent for comparisons between five AEDs regarding the long-term treatment outcomes of monotherapy for adult patients with focal epilepsy in a clinical practice. For selecting AEDs for these patients among the first-line drugs, LTG is an appropriate first choice; others are reservation in the first-line but VPA is not. PMID:26147937

    Endocrine therapy continues to be the optimal systemic treatment for metastatic ER(+)HER2(-) breast cancer. The CDK4/6 inhibitor palbociclib combined with letrozole has recently been shown to significantly improve progression-free survival. Here we examined the cost-effectiveness of this regimen for the Swiss healthcare system. A Markov cohort simulation based on the PALOMA-1 trial (Finn et al. in Lancet Oncol 16:25-35, 2015) was used as the clinical course. Input parameters were based on summary trial data. Costs were assessed from the Swiss healthcare system perspective. Adding palbociclib to letrozole (PALLET) compared to letrozole monotherapy was estimated to cost an additional CHF342,440 and gain 1.14 quality-adjusted life years, resulting in an incremental cost-effectiveness ratio (ICER) of CHF301,227/QALY gained. In univariate sensitivity analyses, no tested variation in key parameters resulted in an ICER below a willingness-to-pay threshold of CHF100,000/QALY. PALLET had a 0 % probability of being cost-effective in probabilistic sensitivity analyses. Lowering PALLET's price by 75 % resulted in an ICER of CHF73,995/QALY and a 73 % probability of being cost-effective. At current prices, PALLET would cost the Swiss healthcare system an additional CHF155 million/year. Palbociclib plus letrozole cannot be considered cost-effective for the first-line treatment of patients with metastatic breast cancer in the Swiss healthcare system. PMID:27277747

    Background. Efficacy of adding bevacizumab in first-line chemotherapy of metastatic colorectal cancer (mCRC) has been controversial. The aim of this study is to gather current data to analyze efficacy of adding bevacizumab to the most used combination first-line chemotherapy in mCRC, based on the 2012 meta-analysis reported by Macedo et al.  Methods. Medline, EMBASE and Cochrane library, meeting presentations and abstracts were searched. Eligible studies were randomized controlled trials (RCTs) which evaluated first-line chemotherapy with or without bevacizumab in mCRC. The extracting data were included and examined in the meta-analysis according to the type of chemotherapy regimen. Results. Seven trials, totaling 3436 patients, were analyzed. Compared with first-line chemothery alone, the adding of bevacizumab did not show clinical benefit for OS both in first-line therapy and the most used combination chemotherapy (HR = 0.89; 95% CI = 0.78–1.02; P = 0.08; HR = 0.93; 95% CI = 0.83–1.05; P = 0.24). In contrast with OS, the addition of bevacizumab resulted in significant improvement for PFS (HR = 0.68; 95% CI = 0.59–0.78; P < 0.00001). Moreover, it also demonstrated statistical benefit for PFS in the most used combination first-line chemotherapy (HR = 0.84; 95% CI = 0.75–0.94; P = 0.002). And the subgroup analysis indicated only capacitabine-based regimens were beneficial. Conclusions. This meta-analysis shows that the addition of bevacizumab to FOLFOX/FOLFIRI/XELOX regimens might not be beneficial in terms of OS. Benefit has been seen when PFS has been taken into account. In subgroup analysis, benefit adding bevacizumab has been seen when capecitabine-based regimens are used. Further studies are warranted to explore the combination with bevacizumab. PMID:24971091

    Abstract Background: We compared efficacy and treatment persistence in treatment-naive patients with relapsing-remitting multiple sclerosis (RRMS) initiating natalizumab compared with interferon-β (IFN-β)/glatiramer acetate (GA) therapies, using propensity score–matched cohorts from observational multiple sclerosis registries. Methods: The study population initiated IFN-β/GA in the MSBase Registry or natalizumab in the Tysabri Observational Program, had ≥3 months of on-treatment follow-up, and had active RRMS, defined as ≥1 gadolinium-enhancing lesion on cerebral MRI at baseline or ≥1 relapse within the 12 months prior to baseline. Baseline demographics and disease characteristics were balanced between propensity-matched groups. Annualized relapse rate (ARR), time to first relapse, treatment persistence, and disability outcomes were compared between matched treatment arms in the total population (n = 366/group) and subgroups with higher baseline disease activity. Results: First-line natalizumab was associated with a 68% relative reduction in ARR from a mean (SD) of 0.63 (0.92) on IFN-β/GA to 0.20 (0.63) (p [signed-rank] < 0.0001), a 64% reduction in the rate of first relapse (hazard ratio [HR] 0.36, 95% confidence interval [CI] 0.28–0.47; p < 0.001), and a 27% reduction in the rate of discontinuation (HR 0.73, 95% CI 0.58–0.93; p = 0.01), compared with first-line IFN-β/GA therapy. Confirmed disability progression and area under the Expanded Disability Status Scale–time curve analyses were not significant. Similar relapse and treatment persistence results were observed in each of the higher disease activity subgroups. Conclusions: This study provides Class IV evidence that first-line natalizumab for RRMS improves relapse and treatment persistence outcomes compared to first-line IFN-β/GA. This needs to be balanced against the risk of progressive multifocal leukoencephalopathy in natalizumab-treated patients. Classification of evidence: This study

    We report on a 90-year-old male patient with a ROS1-translocated adenocarcinoma of the lung who was treated with crizotinib as first-line therapy. After 11 months of treatment, we noticed complete metabolic response as measured by 18F-FDG-PET/CT scan and a partial response according to RECIST criteria. This patient indicates that ROS1 translocations are not restricted to young age, female gender and low stage. Furthermore, this case illustrates exemplarily that crizotinib therapy is effective and manageable even as first-line treatment in elderly patients with comorbidities. Based on our findings, we recommend to include elderly patients with advanced pulmonary adenocarcinomas in molecular screening approaches for ROS1 translocations. PMID:27065847

    There are no evidence-based guidelines as to whether computed tomography (CT) or endoscopy should be selected as the first-line procedure when a nasal tumor is suspected in a dog or a cat and only one examination can be performed. Computed tomography and rhinoscopic features of 17 dogs and 5 cats with a histopathologically or cytologically confirmed nasal tumor were retrospectively reviewed. The level of suspicion for nasal neoplasia after CT and/or rhinoscopy was compared to the definitive diagnosis. Twelve animals underwent CT, 14 underwent rhinoscopy, and 4 both examinations. Of the 12 CT examinations performed, 11 (92%) resulted in the conclusion that a nasal tumor was the most likely diagnosis compared with 9/14 (64%) for rhinoscopies. Computed tomography appeared to be more reliable than rhinoscopy for detecting nasal tumors and should therefore be considered as the first-line procedure. PMID:25694669

    Background Systemic therapy is recommended for advanced non-small-cell lung cancer (NSCLC). However, conventional first-line treatment has generated a plateau in response rate of 25% to 35%. Few studies have shown patients benefit from microwave ablation (MWA) in combination with radiotherapy and chemotherapy. This study aims to evaluate safety and efficacy of percutaneous computed tomography-guided MWA as maintenance after first-line treatment for patients with advanced NSCLC. Methods Patients with histologically verified NSCLC stage IIIB or IV between January 2010 and March 2014 were involved. After completion of first-line treatment with partial response or stable disease, 35 patients with 39 tumors underwent 39 MWA procedures. Complications, progression-free survival (PFS), overall survival (OS), and correlated predictors were analyzed. Results During a median follow-up of 17.7 months and 10.8 months after initial MWA, local efficacy was 87.2%, median MWA-related local control time was 10.6 months, and tumor size was the only predictor (P=0.002). Median MWA-related PFS, MWA-related OS, PFS, and OS were 5.4, 10.6, 11.8 and 17.7 months, respectively. Local efficacy was significantly correlated with MWA-related PFS (P=0.003), MWA-related OS (P=0.000), and OS (P=0.001). There were no procedure-specific deaths. Total incidence of major complications was 12.8%, including pneumothorax resolved by closed pleural drainage and pneumonia controlled by antibiotics in a short time. Conclusion This study concluded two points, including: 1) patients benefited from MWA as maintenance both in local control and survival; 2) as maintenance MWA was superior to conventional maintenance therapy with improved survival and well-tolerated complications. Therefore, MWA was a safe and effective maintenance after first-line treatment in patients with advanced NSCLC. PMID:26604789

    Treatments with bismuth-containing quadruple therapy (QT), sequential therapy (ST), or concomitant therapy (CT) have been proposed as empirical first-line regimens for Helicobacter pylori. We compared the efficacy and tolerability of 10 days bismuth-containing quadruple QT, 10 days ST, and 10 days CT with as first-line treatments for H. pylori in a randomized crossover study. The subjects were randomly divided into three groups. The first 130 patients were treated with rabeprazole, bismuth potassium citrate, metronidazole, and tetracycline for 10 days. The second 130 patients in the sequential group were treated with rabeprazole and amoxicillin for 5 days, and then rabeprazole, clarithromycin, and metronidazole for an additional 5 days. The last 130 patients in the concomitant group were treated with rabeprazole, amoxicillin, clarithromycin, and metronidazole for 10 days. H. pylori eradication was confirmed by urea breath test at 6 weeks. The primary outcome was eradication rates of first-line treatment by intention to treat and per protocol (PP) analyzes. There was no difference between the average ages and the male/female ratio of the groups. The PP analysis was performed on 121, 119, and 118 patients in the QT, ST, and CT groups, respectively. In the PP analysis, the successful eradication 94.2% (114/121), 95.0% (113/119), and 95.8% (113/118) the QT, ST, and CT groups, respectively. There was no significant difference among the three groups (p = 0.86). 10 days QT, ST, and CT are highly effective as empirical first-line therapies for H. pylori in the region with high clarithromycin resistance.

    Purpose: The purpose of this article was to share midterm results of percutaneous cholecystostomy (PC) as a first-line therapy in chronic hemodialysis patients with acute cholecystitis. Methods: Fourteen chronic hemodialysis patients with acute cholecystitis underwent PC between March 2007 and May 2009 at our institute. On preoperative assessment, the patients were classified into the ASA score by the anesthesiology team. All patients were class IV because of severe underlying comorbidities. The patients were referred to interventional radiology unit for PC by consensus of the multidisciplinary team. Results: The PC was technically successful in all the patients without minor or major complications related to the procedure. Clinical symptoms in three patients who presented with sepsis and multiorgan failure did not resolve after PC, and these patients died following urgent surgery, including open cholecystectomy and common bile duct exploration. A new cholecystitis attack was detected in one patient in the acalculous group at the sixth month of the follow-up period. The mean catheterization time was 31.7 (range, 28-41) days. The mean follow-up time was 13.3 (range 4-21) months. Conclusions: The PC may come into consideration as a first-line treatment modality in the management of acute cholecystitis in poor surgical candidate chronic hemodialysis patients. This is the first report focusing on the midterm results of PC as a first-line therapy in hemodialysis patients with acute cholecystitis who could be operated on.

    Background. Human immunodeficiency virus (HIV)-1 drug resistance mutations (DRMs) often accompany treatment failure. Although subtype differences are widely studied, DRM comparisons between subtypes either focus on specific geographic regions or include populations with heterogeneous treatments. Methods. We characterized DRM patterns following first-line failure and their impact on future treatment in a global, multi-subtype reverse-transcriptase sequence dataset. We developed a hierarchical modeling approach to address the high-dimensional challenge of modeling and comparing frequencies of multiple DRMs in varying first-line regimens, durations, and subtypes. Drug resistance mutation co-occurrence was characterized using a novel application of a statistical network model. Results. In 1425 sequences, 202 subtype B, 696 C, 44 G, 351 circulating recombinant forms (CRF)01_AE, 58 CRF02_AG, and 74 from other subtypes mutation frequencies were higher in subtypes C and CRF01_AE compared with B overall. Mutation frequency increased by 9%–20% at reverse transcriptase positions 41, 67, 70, 184, 215, and 219 in subtype C and CRF01_AE vs B. Subtype C and CRF01_AE exhibited higher predicted cross-resistance (+12%–18%) to future therapy options compared with subtype B. Topologies of subtype mutation networks were mostly similar. Conclusions. We find clear differences in DRM outcomes following first-line failure, suggesting subtype-specific ecological or biological factors that determine DRM patterns. PMID:27419147

    Colorectal cancer (CRC) is one of the most commonly occurring cancers worldwide. A burgeoning number of studies have demonstrated that the addition of cetuximab to another standard first-line regimen markedly improves the outcome of CRC treatment. However, at present, the efficacy and safety of cetuximab-based combination chemotherapy has not been well described in Japan. The aim of the present study was to evaluate the efficacy and safety of first-line chemotherapies that included cetuximab for patients with advanced or metastatic Kirsten rat sarcoma viral oncogene homolog (KRAS) wild-type CRC in Japan. This prospective multicenter observational study was conducted at 13 affiliated medical institutions. A total of 64 patients were enrolled between 2010 and 2013. The patients met the following criteria for eligibility: i) histologically confirmed, advanced or metastatic KRAS wild-type CRC; and ii) cetuximab-based chemotherapies administered as a first-line treatment. First-line cetuximab-based treatments were administered as follows: 29 patients (45.3%) received a combination of infusional fluorouracil, leucovorin and oxaliplatin; 14 patients (21.9%) received a combination of capecitabine and oxaliplatin; and 10 patients (15.6%) received a combination of infusional fluorouracil, leucovorin and irinotecan. The overall response rate (including complete plus partial responses) was 50% (32/64 patients). Initially, 48 lesions were diagnosed as unresectable. Among those, 13 lesions (27.1%) were converted to a resectable status following cetuximab-based combination chemotherapy treatments. The median overall survival time and the progression-free survival time were 1,189 and 359 days, respectively. The most frequent grade 3/4 adverse event was neutropenia, which occurred in 20.3% of the patients. The incidence of grade 3/4 skin toxicity was 17.2% (11/64 patients). Cetuximab-based therapies may represent a promising first-line regimen for patients with advanced or

    PurposeThe purpose of this study is to present the outcomes of a series of patients with choroidal neovascular membrane (choroidal neovascularisation (CNV)) secondary to a choroidal osteoma undergoing anti-VEGF monotherapy.Patients and methodsRetrospective series of patients with choroidal neovascularization secondary to choroidal osteoma. All patients underwent clinical and imaging assessment (fundus photo, B-scan ultrasonography, fluorescein angiography, and optical coherence tomography-where available), and were managed with intravitreal anti-VEGF injections (Bevacizumab). Visual acuity and central retinal thickness were recorded pre treatment and at the end of the follow-up period.ResultsEight patients were included in this study. Of this, 6/8 had predominantly classic or classic and 2/8 patients had minimally classic or occult CNV. Each patient received 3-10 injections of bevacizumab. Median follow-up was 9 months (3-15 months). Visual acuity improved in 5 patients, by 2-6 Snellen lines. CNV completely regressed in 5 cases and partially regressed in 3 cases. Mean CRT reduction was 122 μm (6 to -230 μm).ConclusionIntravitreal bevacizumab can be an effective treatment modality in the management of vision threatening CNV secondary to choroidal osteoma.

    Background Clostridium difficile infection (CDI) has become a global epidemiological problem for both hospitalized patients and outpatients. The most commonly used drugs to treat CDI are metronidazole and vancomycin. The aim of this study was to compare the efficacy and safety of metronidazole monotherapy with vancomycin monotherapy and combination therapy in CDI patients. Methods A comprehensive search without publication status or other restrictions was conducted. Studies comparing metronidazole monotherapy with vancomycin monotherapy or combination therapy in patients with CDI were considered eligible. Meta-analysis was performed using the Mantel-Haenszel fixed-effects model, and odds ratios (ORs) with 95% confidence intervals (95% CIs) were calculated and reported. Results Of the 1910 records identified, seventeen studies from thirteen articles (n = 2501 patients) were included. No statistically significant difference in the rate of clinical cure was found between metronidazole and vancomycin for mild CDI (OR = 0.67, 95% CI (0.45, 1.00), p = 0.05) or between either monotherapy and combination therapy for CDI (OR = 1.07, 95% CI (0.58, 1.96), p = 0.83); however, the rate of clinical cure was lower for metronidazole than for vancomycin for severe CDI (OR = 0.46, 95% CI (0.26, 0.80), p = 0.006). No statistically significant difference in the rate of CDI recurrence was found between metronidazole and vancomycin for mild CDI (OR = 0.99, 95% CI (0.40, 2.45), p = 0.98) or severe CDI (OR = 0.98, 95% CI (0.63, 1.53), p = 0.94) or between either monotherapy and combination therapy for CDI (OR = 0.91, 95% CI (0.66, 1.26), p = 0.56). In addition, there was no significant difference in the rate of adverse events (AEs) between metronidazole and vancomycin (OR = 1.18, 95% CI (0.80, 1.74), p = 0.41). In contrast, the rate of AEs was significantly lower for either monotherapy than for combination therapy (OR = 0.30, 95% CI (0.17, 0.51), p<0.0001). Conclusions Metronidazole and

    AIM: To investigate moxifloxacin-containing triple therapy as second-line treatment for Helicobacter pylori (H. pylori) infection following failed first-line treatment. METHODS: The sample included 312 patients for whom first-line treatment failed between January 2008 and May 2013; 27 patients were excluded, and a total of 285 patients received 7- or 14-d moxifloxacin-containing triple therapy as second-line treatment for H. pylori infection. First line regimens included 7-d standard triple (n = 172), 10-d bismuth-containing quadruple (n = 28), 14-d concomitant (n = 37), or 14-d sequential (n = 48) therapy. H. pylori status was evaluated using 13C-urea breath testing 4 wk later, after completion of the treatment. The primary outcome was the H. pylori eradication rate analyzed using intention-to-treat (ITT) and per protocol (PP) analyses. The secondary outcome was the occurrence of serious adverse events. Demographic and clinical factors were analyzed using Student’s t-tests and Pearson’s χ2 tests according to first- and second-line regimens. A P value of less than 0.05 was considered statistically significant. RESULTS: The eradication rate of moxifloxacin-containing triple therapy was 68.4% (ITT; 95%CI: 62.8-73.5) and 73.9% (PP; 95%CI: 68.3-78.8). The eradication rate was significantly higher with 14 d compared to 7 d of treatment (77.5% vs 62.5%, P = 0.017). Peptic ulcer patients had a higher eradication rate than the patients without ulcers (82.9% vs 70.6%, P = 0.046). The demographic and clinical characteristics were not significantly different between the groups according to first-line therapies. ITT and PP analyses of the moxifloxacin-containing triple therapy indicated the following eradication rates: 70.9% (95%CI: 63.8-77.2) and 77.2% (95%CI: 70.1-83.1) for standard triple; 67.9% (95%CI: 51.5-84.2) and 67.9% (95%CI: 51.5-84.2) for bismuth-containing quadruple; 60.4% (95%CI: 46.3-73.0) and 70.7% (95%CI: 54.0-80.9) for sequential; and 67.6% (95%CI: 51

    Efavirenz is the preferred nonnucleoside reverse transcriptase inhibitor (NNRTI) in first-line antiretroviral therapy (ART) regimens in low- and middle-income countries, where the prevalence of diabetes is increasing. Randomized control trials have shown mild increases in plasma glucose in participants in the efavirenz arms, but no association has been reported with overt diabetes. We explored the association between efavirenz exposure and incident diabetes in a large Southern African cohort commencing NNRTI-based first-line ART. Our cohort included HIV-infected adults starting NNRTI-based ART in a private sector HIV disease management program from January 2002 to December 2011. Incident diabetes was identified by the initiation of diabetes treatment. Patients with prevalent diabetes were excluded. We included 56,298 patients with 113,297 patient-years of follow-up (PYFU) on first-line ART. The crude incidence of diabetes was 13.24 per 1000 PYFU. Treatment with efavirenz rather than nevirapine was associated with increased risk of developing diabetes (hazard ratio 1.27 (95% confidence interval (CI): 1.10-1.46)) in a multivariate analysis adjusting for age, sex, body mass index, baseline CD4 count, viral load, NRTI backbone, and exposure to other diabetogenic medicines. Zidovudine and stavudine exposure were also associated with an increased risk of developing diabetes. We found that treatment with efavirenz, as well as stavudine and zidovudine, increased the risk of incident diabetes. Interventions to detect and prevent diabetes should be implemented in ART programs, and use of antiretrovirals with lower risk of metabolic complications should be encouraged. PMID:26945366

    Because many biological processes related to the dynamics of infectious diseases are caused by complex interactions between the environment, the host(s) and the agent(s), the necessity to address the methodological implications of this inherent complexity has recently emerged in epidemiology. Most epidemiologists now acknowledge that most human infectious diseases are likely to have complex dynamics. However, this knowledge still percolates with difficulty in their statistical "modus operandi". Indeed, for the study of complex systems, the traditional first-line statistical toolbox of epidemiologists (mainly built around the Generalized Linear Model family), despite its undeniable practicality and robustness, has structural limitations deprecating its usefulness. Three major sources of complexity neglected or not taken into account by this first-line statistical toolbox and having deep statistical implications are the multi-level organization of data, the non-linear relationships between variables and the complex interactions between variables. Three promising candidates to incorporate along with traditional tools for a new first-line statistical toolbox more suitable to apprehend these sources of complexity are the generalized linear mixed models, the generalized additive models, and the structural equation models. The aforementioned methodologies have the advantage to be generalizations of GLM models and are relatively easy to implement. Their assimilation and implementation would thus be greatly facilitated for epidemiologists. More globally, this text underlines that an improved use of other methods as such described here compared to traditional ones has to be performed to better understand the complexity challenging epidemiologists every day. This is particularly true in the field of infectious diseases for which major public health challenges will have to be addressed in the coming decades. PMID:24035791

  14. Radiofrequency ablation following first-line transarterial chemoembolization for patients with unresectable hepatocellular carcinoma beyond the Milan criteria

    2014-01-01

    Background Recent studies suggest that a combination of radiofrequency ablation (RFA) and transarterial chemoembolization (TACE) may have theoretical advantages over TACE alone for treatment of hepatocellular carcinoma (HCC). The purpose of this study was to evaluate the effectiveness and safety of radiofrequency ablation following first-line TACE treatment in the management of HCC beyond the Milan Criteria. Methods Forty-five patients who consecutively underwent RFA following first-line TACE treatment for HCC beyond the Milan criteria were enrolled in this study. RFA was performed within 1–2 months after TACE treatment in patients who had incomplete necrotic tumor nodules. Primary effectiveness, complications, survival rates, and prognostic factors were evaluated retrospectively. Results Complete ablation was achieved in 76.2% of the lesions according to 1-month follow-up computed tomography/magnetic resonance imaging evaluation. The mean follow-up period was 30.9 months (range 3–94 months). There were no major complications after RFA therapy. The median overall survival was 29 months (range 20–38 months), with 1-, 2-, and 3-year survival of 89%, 61%, and 43%, respectively. Multivariate analysis revealed that tumor diameter (P = 0.045, hazard ratio [HR] = 0.228, 95% confidence interval [CI]: 0.054-0.968) and pretreatment serum alpha-fetoprotein level (P = 0.024, HR = 2.239, 95% CI: 1.114-4.500) were independent predictors for long-term survival. Conclusions HCC beyond the Milan criteria can be completely and safely ablated by radiofrequency ablation following first-line TACE treatment with a low rate of complications and favorable survival outcome. Further assessment of the survival benefits of combination treatment for HCCs beyond the Milan Criteria is warranted. PMID:24410841

    LDH may represent an indirect marker of neo-angiogenesis and worse prognosis in many tumour types. We assessed the correlation between LDH and clinical outcome for biliary tract cancer (BTC) patients treated with first-line chemotherapy. Overall, 114 advanced BTC patients treated with first-line gemcitabine and cisplatin were included. Patients were divided into two groups (low vs. high LDH), according to pre-treatment LDH values. Patients were also classified according to pre- and post-treatment variation in LDH serum levels (increased vs. decreased). Median progression free survival (PFS) was 5.0 and 2.6 months respectively in patients with low and high pre-treatment LDH levels (p = 0.0042, HR = 0.56, 95% CI: 0.37–0.87). Median overall survival (OS) was 7.7 and 5.6 months (low vs. high LDH) (p = 0.324, HR = 0.81, 95% CI: 0.54–1.24). DCR was 71% vs. 43% (low vs. high LDH) (p = 0.002). In 38 patients with decreased LDH values after treatment, PFS and OS were respectively 6.2 and 12.1 months, whereas in 76 patients with post-treatment increased LDH levels, PFS and OS were respectively 3.0 and 5.1 months (PFS: p = 0.0009; HR = 0.49; 95% IC: 0.33–0.74; OS: p < 0.0001; HR = 0.42; 95% IC: 0.27–0.63). Our data seem to suggest that LDH serum level may predict clinical outcome in BTC patients receiving first-line chemotherapy. PMID:27063994

    Background The prevalence of resistance to clarithromycin and metronidazole has considerably increased, with a corresponding decrease in the eradication rate for Helicobacter pylori (H. pylori) infection. Primary resistance to amoxicillin is extremely low, and esomeprazole was found to exert a noteworthy antimicrobial activity in vitro against H. pylori. A dual therapy with high-dose of esomeprazole coupled with high-dose amoxicillin might be therefore an ideal first-line treatment for H. pylori eradication. We aimed to assess the efficacy of a first-line 10-day, high-dose dual therapy consisting of amoxicillin and esomeprazole to eradicate H. pylori infection. Methods Consecutive naïve H. pylori-infected patients, who underwent an upper endoscopy in 4 Italian hospitals due to dyspeptic symptoms and found to be infected at routine histological assessment, were invited to participate. Patients enrolled received a 10-day, high-dose dual therapy comprising esomeprazole (40 mg t.i.d) and amoxicillin (1 g t.i.d.). At least 4 weeks after the end of the treatment a 13C-urea breath test was performed to evaluate the eradication. Results A total of 56 patients agreed to participate in the study and were all followed-up. The overall eradication was 87.5% (95% CI=78.8•96.2), without a statistically significant difference among centres. Overall, 5 (8.9%; 1.5•16.4%) patients complained of side-effects. Conclusions The 10-day, high-dose dual therapy with esomeprazole and amoxicillin might be an effective and safe first-line regimen. The efficacy of a longer 14-day regimen should be tested.

    The deinstitutionalization movement in Canada began in the 1960s. It is defined as the process of discharging chronic mental health patients into the community in order for them to receive care from community mental health services. The deinstitutionalization movement is failing in Canada at this time for two main reasons: (1) the provinces' community mental health programs lack integration; and (2) the negative stigma attached to mental illness is still present in the community. This article will discuss ways to ensure the integration of first-line mental health services and the elimination of stigma through organizational and systemic changes in Canada. PMID:25906464

    Background/Aims Eradication of Helicobacter pylori infection with standard triple therapy (TT) has declined primarily because of increased antibiotic resistance. Sequential therapy (ST) has been suggested as an alternative to TT for the first-line treatment of H. pylori. The purpose of this study was to compare the efficacy of ST with TT. Methods This was a multicenter, randomized open-label trial performed at nine centers in Korea. Patients with H. pylori infection were randomly assigned to receive either 7 day TT or 10 day ST. Eradication rates, drug compliance, and adverse events were compared among the two regimens. Results A total of 601 patients were enrolled between March 2011 and September 2014. The intention-to-treat eradication rates were 70.8% for TT and 82.4% for ST (p=0.001). The corresponding per protocol eradication rates were 76.9% and 88.8% for TT and ST, respectively (p=0.000). There were no statistically significant differences between the two regimens with respect to drug compliance and adverse events. Conclusions ST achieved better eradication rates than TT as a first-line therapy for H. pylori eradication in Korea. PMID:27114421

    Summary Patient autonomy is a concept that implies variable degrees of patient participation in different aspects of health and healthcare, including the choice of therapy. This study, conducted in patients with multiple sclerosis (MS), examined several factors in relation to the patient’s role in the therapeutic decision-making process. One hundred newly diagnosed patients with MS attending their first ever specialist consultation at the MS center of Catania, Italy, were consecutively enrolled in a single-center, open, observational study. Clinical and demographic data were collected as part of this routine first consultation. Through administration of the Control Preferences Scale, we ascertained the patients’ willingness to participate in the decision-making process on their first-line treatment, classifying them, on the basis of their attitude, as passive, collaborative or active. Of 100 patients with MS, 40 had a passive attitude, while 35 were willing to collaborate and 25 wanted to play an active role in the decision-making process. The patients showing an active attitude had a significantly higher Expanded Disability Status Scale score and a significantly higher number of relapses (p<0.5 for both) than those who showed other attitudes. Persons with MS prefer to know the benefits and risks related to the first-line treatment. Those with higher disability prefer to be active in the decision-making process. PMID:27027890

    The treatment efficacy of advanced breast cancer is still not promising. This study aimed to compare the efficacy and safety of docetaxel/S-1 (DS1) versus docetaxel/capecitabine (DX) as the first-line treatment for advanced breast cancer.From June 2008 to June 2013, 22 patients with advanced breast cancer were treated with the DS1 regimen. Another 26 age- and disease status-matched patients treated with the DX regimen served as controls. The 2 groups were compared in terms of time to progression (TTP), objective response rate, disease control rate, clinical benefit rate, and safety profiles.Median TTP did not differ significantly between the DS1 group and the DX group (9.04 vs 10.94 months, P = 0.473). There were no significant differences in objective response rate, disease control rate, and clinical benefit rate between the 2 groups. Both the DS1 and the DX regimens showed good tolerability. The 2 regimens showed no significant difference in adverse events except degree III hand-foot syndrome (DS1 0 vs DX 23.1%, P = 0.025).For the first-line treatment of advanced breast cancer, the DS1 and the DX regimens showed similar efficacy and safety. The DS1 regimen had less severe hand-foot syndrome than the DX regimen. PMID:26469889

    Intraperitoneal treatment with interferon-γ (IFN-γ) has been shown to achieve surgically documented responses in the second-line therapy of ovarian cancer. To assess its efficacy in the first-line therapy, we conducted a randomized controlled trial with 148 patients who had undergone primary surgery for FIGO stage Ic–IIIc ovarian cancer. In the control arm women received 100 mg m−2cisplatin and 600 mg m−2cyclophosphamide, the experimental arm included the above regimen with IFN-γ 0.1 mg subcutaneously on days 1, 3, 5, 15, 17 and 19 of each 28-day cycle. Progression-free survival at 3 years was improved from 38% in controls to 51% in the treatment group corresponding to median times to progression of 17 and 48 months (P = 0.031, relative risk of progression 0.48, confidence interval 0.28–0.82). Three-year overall survival was 58% and 74% accordingly (n.s., median not yet reached). Complete clinical responses were observed in 68% with IFN-γ versus 56% in controls (n.s.). Toxicity was comparable in both groups except for a mild flu-like syndrome, experienced by most patients after administration of IFN-γ. Thus, with acceptable toxicity, the inclusion of IFN-γ in the first-line chemotherapy of ovarian cancer yielded a benefit in prolonging progression-free survival. © 2000 Cancer Research Campaign PMID:10735496

    Introduction First-line antiretroviral therapy (ART) failure often results from the development of resistance-associated mutations (RAMs). Three patterns, including thymidine analogue mutations (TAMs), 69 Insertion (69Ins) and the Q151M complex, are associated with resistance to multiple-nucleoside reverse transcriptase inhibitors (NRTIs) and may compromise treatment options for second-line ART. Methods We investigated patterns and factors associated with multi-NRTI RAMs at first-line failure in patients from The TREAT Asia Studies to Evaluate Resistance – Monitoring study (TASER-M), and evaluated their impact on virological responses at 12 months after switching to second-line ART. RAMs were compared with the IAS-USA 2013 mutations list. We defined multi-NRTI RAMs as the presence of either Q151M; 69Ins; ≥2 TAMs; or M184V+≥1 TAM. Virological suppression was defined as viral load (VL) <400 copies/ml at 12 months from switch to second-line. Logistic regression was used to analyze (1) factors associated with multi-NRTI RAMs at first-line failure and (2) factors associated with virological suppression after 12 months on second-line. Results A total of 105 patients from 10 sites in Thailand, Hong Kong, Indonesia, Malaysia and Philippines were included. There were 97/105 (92%) patients harbouring ≥1 RAMs at first-line failure, 39/105 with multi-NRTI RAMs: six with Q151M; 24 with ≥2 TAMs; and 32 with M184V+≥1 TAM. Factors associated with multi-NRTI RAMs were CD4 ≤200 cells/µL at genotyping (OR=4.43, 95% CI [1.59–12.37], p=0.004) and ART duration >2 years (OR=6.25, 95% CI [2.39–16.36], p<0.001). Among 87/105 patients with available VL at 12 months after switch to second-line ART, virological suppression was achieved in 85%. The median genotypic susceptibility score (GSS) for the second-line regimen was 2.00. Patients with ART adherence ≥95% were more likely to be virologically suppressed (OR=9.33, 95% CI (2.43–35.81), p=0.001). Measures of patient

    Background Mefloquine and artesunate combination therapy is the recommended first-line treatment for uncomplicated malaria throughout much of south-east Asia. Concerns have been raised about the potential central nervous system (CNS) effects of both drug components and there are no detailed reports in very young children. Methods Children, aged between three months and five years, with acute uncomplicated Plasmodium falciparum malaria were randomized to either 7 days of artesunate monotherapy or the same schedule of artesunate plus mefloquine on day 7 and 8. Neurological testing targeting coordination and behaviour was carried out at day 0, 7, 9, 10, 14 and 28. Non-febrile healthy control children from the same population were tested on days 0, 7, 14 and 28. Results From December 1994 to July 1997, 91 children with uncomplicated P. falciparum, 45 treated with artesunate monotherapy, 46 treated with mefloquine and artesunate combination therapy and 36 non-febrile controls, underwent neurological testing. Malaria and fever had a significant negative impact on testing performance. By contrast, the anti-malarial treatments were not associated with worsening performances in the various components of the test. Artesunate and mefloquine do not appear to have a significant influence on coordination and behaviour. Children treated with mefloquine were significantly less likely to suffer recurrent malaria infection during follow-up compared to those treated with artesunate alone (P = 0.033). Conclusion In keeping with the results of randomized controlled trials in adults, mefloquine was not associated with a decrease in specific items of neurological performance. Likewise, children treated with artesunate did not perform significantly differently to control children. This study does not exclude subtle or rare treatment CNS effects of artesunate or mefloquine. Treatment of acute uncomplicated malaria results in a significant improvement on items of neurological performance

    Background Antiretroviral therapy (ART) has evolved rapidly since its beginnings. This analysis describes trends in first-line ART use in Asia and their impact on treatment outcomes. Methods Patients in the TREAT Asia HIV Observational Database receiving first-line ART for ≥6 months were included. Predictors of treatment failure and treatment modification were assessed. Results Data from 4662 eligible patients was analysed. Patients started ART in 2003–2006 (n = 1419), 2007–2010 (n = 2690) and 2011–2013 (n = 553). During the observation period, tenofovir, zidovudine and abacavir use largely replaced stavudine. Stavudine was prescribed to 5.8% of ART starters in 2012/13. Efavirenz use increased at the expense of nevirapine, although both continue to be used extensively (47.5% and 34.5% of patients in 2012/13, respectively). Protease inhibitor use dropped after 2004. The rate of treatment failure or modification declined over time (22.1 [95%CI 20.7–23.5] events per 100 patient/years in 2003–2006, 15.8 [14.9–16.8] in 2007–2010, and 11.6 [9.4–14.2] in 2011–2013). Adjustment for ART regimen had little impact on the temporal decline in treatment failure rates but substantially attenuated the temporal decline in rates of modification due to adverse event. In the final multivariate model, treatment modification due to adverse event was significantly predicted by earlier period of ART initiation (hazard ratio 0.52 [95%CI 0.33–0.81], p = 0.004 for 2011–2013 versus 2003–2006), older age (1.56 [1.19–2.04], p = 0.001 for ≥50 years versus <30years), female sex (1.29 [1.11–1.50], p = 0.001 versus male), positive hepatitis C status (1.33 [1.06–1.66], p = 0.013 versus negative), and ART regimen (11.36 [6.28–20.54], p<0.001 for stavudine-based regimens versus tenofovir-based). Conclusions The observed trends in first-line ART use in Asia reflect changes in drug availability, global treatment recommendations and

    AIM: To investigate the long-term survival and prognostic factors in hepatocellular carcinoma (HCC) patients undergoing radiofrequency ablation (RFA) as a first-line treatment. METHODS: From 2000 to 2013, 316 consecutive patients with 404 HCC (1.0-5.0 cm; mean: 3.2 ± 1.1 cm) underwent ultrasonography-guided percutaneous RFA as a first-line treatment. There were 250 males and 66 females with an average age of 60.1 ± 10.8 years (24-87 years). Patients were followed for 1 year to > 10 years after RFA (234, 181, 136, and 71 for 3, 5, 7, and 10 years, respectively). Overall local response rates and long-term survival rates were assessed. Survival results were generated using Kaplan-Meier estimates, and multivariate analysis was performed using the Cox regression model. RESULTS: In total, 548 RFA sessions were performed and major complications occurred in 10 sessions (1.8%). Local tumor progression and/or new tumor development were observed in 43.3% (132/305) of the patients during the follow-up period. Overall 5- and 10-year survival rates were 49.7% and 28.4%, respectively. Based on multivariate analysis, three factors were identified as independent prognostic factors for overall survival: Child-Pugh classification (HR = 4.054, P < 0.001), portal vein hypertension (HR = 2.743, P = 0.002), and tumor number (HR = 2.693, P = 0.003). The local progression-free 5- and 10-year survival rates were 42.7% and 19.5%. In addition to the Child-Pugh classification and the number of tumors, the number of RFA sessions (HR = 1.550, P = 0.002) was associated with local progression-free survival. CONCLUSION: RFA can achieve acceptable outcomes for HCC patients as a first-line treatment, especially for patients with Child-Pugh class A, patients with a single tumor and patients without portal vein hypertension.

    During these last years, there have been an increased number of new drugs for non-small cell lung cancer (NSCLC), with a growing financial effect on patients and society. The purpose of this article was to review the economics of first-line and maintenance NSCLC treatments. We reviewed economic analyses of NSCLC therapies published between 2004 and 2014. In first-line settings, in unselected patients with advanced NSCLC, the cisplatin gemcitabine doublet appears to be cost-saving compared with other platinum doublets. In patients with nonsquamous NSCLC, the incremental cost-effectiveness ratios (ICERs) per life-year gained (LYG) were $83,537, $178,613, and more than $300,000 for cisplatin-pemetrexed compared with, respectively, cisplatin-gemcitabine, cisplatin-carboplatin-paclitaxel, and carboplatin-paclitaxel-bevacizumab. For all primary chemotherapy agents, use of carboplatin is associated with slightly higher costs than cisplatin. In all the analysis, bevacizumab had an ICER greater than $150,000 per quality-adjusted life-year (QALY). In epidermal growth factor receptor mutated advanced NSCLC, compared with carboplatin-paclitaxel doublet, targeted therapy based on testing available tissue yielded an ICER of $110,644 per QALY, and the rebiopsy strategy yielded an ICER of $122,219 per QALY. Compared with the triplet carboplatin-paclitaxel-bevacizumab, testing and rebiopsy strategies had ICERs of $25,547 and $44,036 per QALY, respectively. In an indirect comparison, ICERs per LYG and QALY of erlotinib versus gefitinib were $39,431 and $62,419, respectively. In anaplastic lymphoma kinase-positive nonsquamous advanced NSCLC, the ICER of first-line crizotinib compared with that of chemotherapy was $255,970 per QALY. For maintenance therapy, gefitinib had an ICER of $19,214 per QALY, erlotinib had an ICER of $127,343 per LYG, and pemetrexed had an ICER varying between $183,589 and $205,597 per LYG. Most recent NSCLC strategies are based on apparently no cost

    The increasing appreciation of oncogenic driver alterations in non-small cell lung cancer (NSCLC) has resulted in a rapid expansion of therapeutic compounds. Epidermal growth factor receptor (EGFR) and anaplastic lymphoma kinase (ALK) alterations are the prototypical examples and have driven the paradigm shift in NSCLC management. Early phase studies in previously treated ALK+ patients demonstrated activity and recently Solomon et al. confirmed the superiority of crizotinib over chemotherapy in first line treatment. The phase III PROFILE 1014 represents the culmination of the rapid development of crizotinib and provides lessons for future generation ALK inhibitors and other molecularly directed therapies in NSCLC. Important considerations for second and third generation inhibitors include the ability to overcome known resistance mechanisms, CNS activity, improvement in side effect profile, and safety in possible combination strategies.

    Abstract: CD4 count testing is perceived to be an affordable strategy to diagnose treatment failure on first-line antiretroviral therapy. We hypothesize that the superior accuracy of viral load (VL) testing will result in less patients being incorrectly switched to more expensive and toxic second-line regimens. Using data from a drug resistance cohort, we show that CD4 testing is approximately double the cost to make 1 correct regimen switch under certain diagnostic thresholds (CD4 = US $499 vs. VL = US $186 or CD4 = US $3031 vs. VL = US $1828). In line with World Health Organization guidelines, our findings show that VL testing can be both an accurate and cost-effective treatment monitoring strategy. PMID:26484740

    We investigate mutations and correlates according to HIV-1 subtype after virological failure (VF) of standard first-line antiretroviral therapy (ART) (non-nucleoside/nucleotide reverse transcriptase inhibitor [NNRTI] +2 nucleoside/nucleotide reverse transcriptase inhibitor [N(t)RTI]). SECOND-LINE study participants were assessed at baseline for HIV-1 subtype, demographics, HIV-1 history, ART exposure, viral load (VL), CD4(+) count, and genotypic ART resistance. We used backward stepwise multivariate regression (MVR) to assess associations between baseline variables and presence of ≥3 N(t)RTI mutations, ≥1 NNRTI mutation, ≥3 thymidine analog-N(t)RTI [ta-N(t)RTI] mutations (TAMs), the K65/K70 mutation, and predicted etravirine (ETV)/rilpivirine (RPV) activity. The inclusion p-value for MVR was p < .2. The exclusion p-value from stepwise elimination was p > .05. Of 541 participants, 491 (91%) had successfully characterized baseline viral isolates. Subtype distribution: B (n = 123, 25%), C (n = 202, 41%), CRF01_AE (n = 109, 22%), G (n = 25, 5%), and CRF02_AG (n = 27, 5%). Baseline CD4(+) 200-394 cells/mm(3) were associated with <3 N(t)RTI mutations (OR = 0.47; 95% CI 0.29-0.77; p = .003), absence of the K65/K70 mutation (OR = 0.43; 95% CI 0.26-0.73; p = .002), and higher ETV sensitivity (OR = 0.52; 95% CI 0.35-0.78; p = .002). Recent tenofovir (TDF) use was associated with K65/K70 mutations (OR = 8.91; 95% CI 5.00-15.85; p < .001). Subtype CRF01_AE was associated with ≥3 N(t)RTI mutations (OR = 2.34; 95% CI 1.31-4.17; p = .004) and higher RPV resistance (OR = 2.13; 95% CI 1.30-3.49; p = .003), and subtype C was associated with <3 TAMs (OR = 0.45; 95% CI 0.21-0.99; p = .015). Subtypes CRF01_AE (OR = 2.46; 95% CI 1.26-4.78; p = .008) and G (OR = 4.77; 95% CI 1.44-15.76; p = .01) were associated with K65/K70 mutations. Higher VL at confirmed first-line VF was

    The mucosal immune system acts as a first line of defense against bacterial and viral infections while also playing a crucial role in the establishment and maintenance of mucosal homeostasis between the host and the outside environment. In addition to epithelial cells and antigen-presenting cells (dendritic cells and macrophages), B and T lymphocytes form a dynamic mucosal network for the induction and regulation of secretory IgA (S-IgA) and cytotoxic T lymphocyte (CTL) responses. This review seeks to shed light on the pathways of induction and regulation of these responses and to elucidate the role they simultaneously play in fending off pathogen invasion and maintaining mucosal homeostasis.

    Introduction Acquired severe aplastic anemia (SAA) is a rare and progressive disease characterized by an immune-mediated functional impairment of hematopoietic stem cells. Transplantation of these cells is a first-line treatment option if HLA-matched related donors are available. First-line immunosuppressive therapy may be offered as alternative. The aim was to compare the outcome of these patients in controlled trials. Methods A systematic search was performed in the bibliographic databases MEDLINE, EMBASE, and The Cochrane Library. To show an overview of various outcomes by treatment group we conducted a meta-analysis on overall survival. We evaluated whether studies reported statistically significant factors for improved survival. Results 26 non-randomized controlled trials (7,955 patients enrolled from 1970 to 2001) were identified. We did not identify any RCTs. Risk of bias was high except in 4 studies. Young age and recent year of treatment were identified as factors for improved survival in the HSCT group. Advanced age, SAA without very severe aplastic anemia, and combination of anti-lymphocyte globulin with cyclosporine A were factors for improved survival in the IST group. In 19 studies (4,855 patients), summary statistics were sufficient to be included in meta-analysis. Considerable heterogeneity did not justify a pooled estimate. Adverse events were inconsistently reported and varied significantly across studies. Conclusions Young age and recent year of treatment were identified as factors for improved survival in the transplant group. Advanced age, SAA without very severe aplastic anemia, and combination of anti-lymphocyte globulin with cyclosporine A were factors for improved survival in the immunosuppressive group. Considerable heterogeneity of non-randomized controlled studies did not justify a pooled estimate. Adverse events were inconsistently reported and varied significantly across studies. PMID:21541024

    Purpose: Patients with epidermal growth factor receptor (EGFR) mutation–positive stage IV adenocarcinoma have improved survival with tyrosine kinase inhibitor (TKI) treatments, but the cost effectiveness of personalized first-line therapy using EGFR mutation testing is unknown. Methods: We created a decision analytic model comparing the costs and effects of platinum combination chemotherapy with personalized therapy in which patients with EGFR mutation–positive tumors were treated with erlotinib. We used two testing strategies: testing only those with tissue available and performing a repeat biopsy if tissue was not available versus three nontargeted chemotherapy regimens (ie, carboplatin and paclitaxel; carboplatin and pemetrexed; and carboplatin, pemetrexed, and bevacizumab). Results: Compared with a carboplatin plus paclitaxel regimen, targeted therapy based on testing available tissue yielded an incremental cost-effectiveness ratio (ICER) of $110,644 per quality-adjusted life year (QALY), and the rebiopsy strategy yielded an ICER of $122,219 per QALY. Probabilistic sensitivity analysis revealed substantial uncertainty around these point estimates. With a willingness to pay of $100,000 per QALY, the testing strategy was cost effective 58% of the time, and the rebiopsy strategy was cost effective 54% of the time. Personalized therapy with an EGFR TKI was more favorable when the nontargeted chemotherapy regimen was more expensive. Compared with carboplatin, pemetrexed, and bevacizumab, ICERs were $25,547 per QALY for the testing strategy and $44,036 per QALY for the rebiopsy strategy. Conclusion: Although specific clinical circumstances should guide therapy, our cost-effectiveness analysis supports the strategy of testing for EGFR mutations in patients with stage IV or recurrent adenocarcinoma of the lung, rebiopsying patients if insufficient tissue is available for testing, and treating patients with EGFR mutations with erlotinib as first-line therapy.

    Population level variation of drug metabolism phenotype (DMP) has great implications in treatment outcome, drug-related side effects, and resistance development. In this study, we used a gas chromatography-time of flight-mass spectrometry (GC-TOF-MS)-based untargeted urine metabolomics approach to understand the DMP of a tuberculosis (TB) patient cohort (n= 20) from Tripura, a state in the northeastern part of India. Urine samples collected at different postdose time points (2 h, 6 h, 12 h, 24 h, 36 h, and 48 h) from these newly diagnosed TB patients receiving first-line anti-TB drugs were analyzed, and we have successfully detected three of the four first-line drugs,viz, isoniazid (INH), ethambutol (ETB), and pyrazinamide (PZA). The majority of their known metabolites, acetyl-isoniazid (AcINH), isonicotinic acid (INA), isonicotinuric acid (INTA), 2,2'-(ethylenediimino)-dibutyric acid (EDBA), 5-hydroxypyrazinamide (5OH-PZA), pyrazinoic acid (POA), and 5-hydroxypyrazinoic acid (5OH-POA), were also detected. Analyzing the variation in abundances of drugs and their known metabolites and calculating the metabolic ratios in these samples, we offer comprehensive DMP information on this small patient cohort that represents Tripura, India. The majority (75%) of these patients are found to be slow acetylators of INH. The average metabolic ratios of POA/PZA and 5OH-POA/POA are 3.16 ± 3.03 and 6.09 ± 6.15, respectively. Employing correlation analysis of the metabolomics metadata and a manual prediction of drug catabolism, we have proposed 2-aminobutyric acid (AABA) as a novel metabolite of ETB. These observations indicate the usefulness of GC-MS-based metabolomics to characterize the DMP at a population level and also to identify novel drug metabolites. PMID:26833163

    To determine whether molecular parameters could be partly responsible for resistance or sensitivity to oxaliplatin (OX)-based chemotherapy used as first-line treatment in advanced colorectal cancer (CRC). We studied the usefulness of the excision repair cross-complementing 1 (ERCC1), xeroderma pigmentosum group D (XPD), XRCC1 and GSTP1 polymorphisms as predictors of clinical outcome in these patients. We treated 126 CRC patients with a first-line OX/5-fluorouracil chemotherapeutic regimen. Genetic polymorphisms were determined by real-time PCR on an ABI PRISM 7000, using DNA from peripheral blood. Clinical response (CR), progression-free survival (PFS) and overall survival (OS) were evaluated according to each genotype. In the univariate analysis for CR, ERCC1-118 and XPD 751 polymorphisms were significant (P=0.02 and P=0.05, respectively). After adjustment for the most relevant clinical variables, only ERCC1-118 retained significance (P=0.008). In the univariate analysis for PFS, ERCC1-118 and XPD 751 were significant (P=0.003 and P=0.009, respectively). In the multivariant analysis, only the XPD 751 was significant for PFS (P=0.02). Finally, ERCC1-118 and XPD 751 polymorphisms were significant in the univariate analysis for OS (P=0.006 and P=0.015, respectively). Both genetic variables remained significant in the multivariate Cox survival analysis (P=0.022 and P=0.03). Our data support the hypothesis that enhanced DNA repair diminishes the benefit of platinum-based treatments. PMID:18797464

    This retrospective study aimed at evaluating the long-term outcomes and prognostic factors of microwave ablation (MWA) as a first-line treatment for hepatocellular carcinoma (HCC). 221 consecutive patients receiving MWA in our center between October 11, 2010 and December 31, 2013 were enrolled. Technique effectiveness was evaluated one month post-ablation. Initial complete ablation (CA1(st)) was gained in 201 (90.95%) patients, secondary CA (CA2(nd)) in 8 (3.62%) patients and the remaining 12 (5.43%) patients suffered from incomplete ablation (IA2(nd)) after two sessions of MWA. Patients with tumor size >5 cm were less likely to gain CA1(st). Procedure-related complications were recorded and no procedure-related death occurred. 22 (10.4%) complications occurred with 8 (3.8%) being major ones. Tumor characteristics (size, number, location) do not significantly influence complication rates. After a median follow-up of 41.0 (ranging 25.0-63.5) months, the median RFS and OS was 14.0 months (95% CI: 9.254-18.746) and 41.0 months (95% CI: 33.741-48.259) respectively. Multivariate analysis identified two significant prognosticators (levels of alpha fetal protein [AFP] and gamma-glutamyl transpeptidase [GGT]) of RFS and five significant prognosticators (tumor number, tumor size, AFP, GGT and recurrence type) of OS. In conclusion, MWA provides high technique effectiveness rate and is well tolerated in patients with HCC as a first-line treatment. PMID:27620527

    Objective: To confirm that either Fibrinolytic therapy or open decortication which of the two is an effective First line treatment of pleural empyema. Methods: This prospective comparative study was conducted in the department of surgery Sheikh Zayed Medical College and Hospital, Rahim Yaar Khan. Seventy eight (78) patients were included in this study. There were two groups of patients; Group I (n=35) patients treated with fibrinolytic therapy, Group II (n=43) patients treated with open decortication. Data was entered and analyzed in SPSS v16. Student’s t-test was used for comparison of quantitative variables. Chi-square and Fisher’s Exact test were used for comparison of qualitative variables. P-value ≤ 0.05 was taken as significant difference. Results: There was no significant difference in base baseline characteristics of patients of Group I and II. Incidence of comorbidities was also same between the groups. Most of the patients in Group I and II were in empyema stage III. Fluid cultures was positive in 33 (94.3%) patients in group I and 39 (90.7%) patients in group II. 30 (85.7%) was successfully treated using fibrinolytic therapy but this therapy failed in five (14.3%) patients, two of these patients expired within the hospital. There was only one (2.3%) treatment failure in open decortication Group that patient expired within the hospital (p-value 0.04). Overall duration of hospitalization was significantly high in fibrinolytic group, this was 17.6± 1.95 days versus 12.09± 2.18 days in open decortication group (p-value<0.0001). There was no significant difference regarding operative mortality within the two groups. Conclusion: Open Drainage is associated with better outcomes as compared to fibrinolytic therapy when used as a First line treatment of empyema. PMID:27182233

    Although clinical improvement is almost universal with therapy in patients with POEMS (an acronym for polyneuropathy, organomegaly, endocrinopathies, monoclonal protein and a variety of skin changes) syndrome, outcomes and management of patients who relapse or progress (R/P) after first-line treatment have not been described. We retrospectively identified 262 patients with POEMS syndrome treated at the Mayo Clinic from 1974 to 2014 and who had follow-up information. The 5-year progression-free survival (PFS) and overall survival (OS) was 58% and 78%, respectively. Median time to R/P was 42 months. Seventy-nine patients (30%) had an R/P, with 52 (19%) experiencing a symptomatic R/P. Eighteen patients relapsed with symptoms or signs that were not documented at diagnosis. Median times to vascular endothelial growth factor, hematologic, radiographic and clinical R/P were 35 months (range, 4-327 months), 72 months (range, 4-327 months), 51 months (range, 4-327 months) and 48 months (range, 6-311 months), respectively. On multivariate analyses, low albumin at diagnosis and failure to achieve a complete hematologic response to first-line therapy were independent risk factors for PFS. Thirty patients had documentation of a second R/P at a median of 26 months from diagnosis of the first R/P. An early R/P was a risk factor for death, but most patients with an R/P had salvageable disease. A majority of patients are still without R/P at 5 years from diagnosis. PMID:26669974

    The first FDA-approved multiplex PCR panel for a large number of respiratory pathogens was introduced in 2008. Since then, other PCR panels for detection of several respiratory and gastrointestinal pathogens have been approved by the FDA and are commercially available, and more such panels are likely to become available. These assays detect 12 to 20 pathogens, and some include pathogens that typically cause different manifestations of infection, although they infect the same organ system. Some of these tests are labor-intensive, while others require little labor, and all of them are expensive, both for the laboratory and for the patient or insurer. They include a bundle of tests with limited or no options for selecting which tests will be performed. Laboratories and hospitals have adopted different strategies for offering these assays. Some have implemented strategies to limit the use of the tests, such as limiting the frequency with which patients can be tested, restricting testing to specific groups of patients (e.g., immunocompromised patients), or providing education to encourage the use of less expensive tests before using large multiplex panels. Others have offered these assays without limiting their use, either relying on the ordering provider to exercise good judgment or because such assays are thought to be appropriate for first-line diagnostic testing. In this Point-Counterpoint, Paul Schreckenberger of Loyola University Medical Center explains why his laboratory offers these assays without restriction. Alex McAdam of Boston's Children Hospital explains the concerns about the use of these assays as first-line tests and why some limitations on their use might be appropriate. PMID:25762770

    Purpose: Methotrexate, vinblastine, doxorubicin plus cisplatin (MVAC) and gemcitabine plus cisplatin (GC) are both effective first-line chemotherapy. We explore the responsive variables of MVAC and GC for patients with metastatic urothelial carcinoma of bladder (mUCB). Materials and Methods: Patients who were initially diagnosed to have mUCB and received MVAC or GC as metastatic first-line chemotherapy between 2000 and 2014 at Kaohsiung Chang Gung Memorial Hospital were reviewed. Totally, 130 patients were enrolled into our study. Univariable Cox proportional hazard models were constructed for OS. Hazard ratio (HR) and 95% confidence intervals (CIs) was also presented. Results: There were 50 patients (38%) in the MVAC group and 80 patients (62%) in the GC group. The median OS was insignificantly different between MVAC and GC groups, accounting for 17.0 and 14.4 months (P = 0.214), respectively. OS of MVAC group was significantly longer with regard to age ≦ 60 years (HR: 0.38, 95% CI: 0.12-0.97, P = 0.036), pure urothelial carcinoma (HR: 0.56, 95% CI: 0.34-0.90, P = 0.015), > 1 metastatic sites (HR: 0.19, 95% CI: 0.08-0.44, P = < 0.001), and neutrophil to lymphocyte ratio > 3(HR: 0.45, 95% CI: 0.25-0.81, P = 0.006), while OS with GC group was significantly longer with regard to variant urothelial carcinoma (HR: 0.56, 95% CI: 0.34-0.90, P = 0.015). Conclusions: Our study disclosed the predictive factors of different regimen for mUCB. These results have clinical implication for physicians who treat patients with mUCB. PMID:27390610

    Aim: Cytotoxic chemotherapy is the standard first-line therapy for patients with advanced non-small cell lung cancer (NSCLC) without specific gene alterations. This study examined the prescription pattern and the survival outcome of cytotoxic chemotherapy regimens in daily practice in Taiwan. Methods:We established a population-based cohort of patients diagnosed with advanced NSCLC between 2005 and 2009 using the databases of Taiwan Cancer Registry and National Health Insurance in Taiwan. We then analyzed chemotherapy prescriptions and the survival outcomes of patients. Results:A total of 25,008 patients with advanced NSCLC were identified, 17,443 (70.0%) of which received first-line chemotherapy and were therefore included in this study. Among them, 11,551 (66.2%) patients had adenocarcinoma and 3,292 (18.9%) patients had squamous cell carcinoma (SCC). Approximately 70% of the patients were diagnosed with NSCLC in medical centers. Platinum-based doublet chemotherapy was administered to 66.9% of the patients. Among all chemotherapy regimens, platinum with gemcitabine (33.8%) was the most common, irrespective of geographic region. The second and third most common regimens were vinorelbine alone (13.0%) and platinum with docetaxel (11.6%). The prevalence of platinum-based doublet chemotherapy regimens decreased from 71.4% in 2005 to 64.1% in 2009. Among patients with adenocarcinoma histology, those who received platinum with pemetrexed had longer OS than did patients who received other platinum-based regimens (p < 0.001). Conclusion: Our findings reaffirm that in real-world practice, treatment plans of advanced NSCLC should be drawn up according to histology type. PMID:27471567

    2009-01-01

    Background Psychotic depression is a clinical subtype of major depressive disorder. A number of clinical studies have demonstrated the efficacy of the combination of an antidepressant (for example, a tricyclic antidepressant or selective serotonin reuptake inhibitor (SSRI)) and an atypical antipsychotic or electroconvulsive therapy in treating psychotic depression. In some cases, the clinician or patient may prefer to avoid antipsychotic drugs altogether because of the risk of extrapyramidal side effects (EPS) in patients with psychotic depression treated with these drugs. Methods We report five cases where fluvoxamine monotherapy was effective in the patients with psychotic depression. Results The scores on the Hamilton Depression (HAM-D) scale and the Brief Psychiatric Rating Scale (BPRS) in the five patients with psychotic depression were reduced after fluvoxamine monotherapy. Conclusion Doctors should consider fluvoxamine monotherapy as an alternative approach in treating psychotic depression because it avoids the risk of EPS from antipsychotic drugs. PMID:20025739

    versus docetaxel in terms of overall survival. The manufacturer developed a de novo economic model that considered patients with the same baseline characteristics as women in the E2100 trial. The model assessed BEV + PAC - bevacizumab 10 mg/kg every 2 weeks in combination with paclitaxel 90 mg/m2 weekly for 3 weeks followed by 1 week of rest; PAC q.w. - paclitaxel (monotherapy) 90 mg/m2 weekly for 3 weeks followed by 1 week of rest; DOC - docetaxel (monotherapy) 75 mg/m2 on day 1 every 21 days (considered current UK NHS clinical practice in the submission); and GEM + PAC - gemcitabine 1250 mg/m2 on days 1 and 8 plus paclitaxel 175 mg/m2 on day 1 every 21 days. Pairwise comparisons were made between BEV + PAC and PAC (using the E2100 trial), BEV + PAC and DOC, and BEV + PAC and GEM + PAC. Based on NHS list prices, the manufacturer's model estimated incremental cost-effectiveness ratios (ICERs) for BEV + PAC of £ 117,803, £ 115,059 and £ 105,777 per QALY gained, relative to PAC, DOC and GEM + PAC regimens, respectively. If the NHS Purchasing and Supply Agency prices for PAC with a 10-g cap on the cost per patient of BEV were used instead, the ICERs for BEV + PAC were estimated at £ 77,314, £ 57,753 and £ 60,101 per QALY, respectively. The submission suggested that the regimen of BEV + DOC is not cost-effective because it is considered less effective and more costly than BEV + PAC. Analysis by the ERG suggested that alternative assumptions can increase the ICERs further and, based on current prices, no plausible changes to the model assumptions will bring the ICERs for BEV + PAC lower.

    Objective: To compare WHO first-line antiretroviral therapy (ART) with nonnucleoside reverse transcriptase inhibitors (NNRTI)-based regimen with a boosted protease inhibitor (bPI) regimen in a resource-limited setting regarding treatment outcome and emergence of drug resistance mutations (DRMs). Methods: Treatment-naive adults were randomized to nevirapine (NVP) or ritonavir-boosted lopinavir (LPV/r) regimens each in combination with tenofovir (TDF)/emtricitabine (FTC) or zidovudine (ZDV)/lamivudine (3TC). Primary endpoint was the incidence of therapeutical (clinical and/or virologic) failure at week 48 with follow-up till week 96. Results: Four hundred and twenty-five patients (120 men; 305 women) received at least one dose of the study drug. mITT analysis showed no difference in proportion of therapeutical failure between treatment arms [67/209 (32%) in NVP vs. 63/216 (29%) LPV/r at week 48 (P = 0.53); 88/209 (42%) in NVP vs. 83/216 (38%) in LPV/r at week 96 (P = 0.49)]. Per-protocol analysis demonstrated significantly more virologic failure with NVP than with LPV/r regimens [at week 48: 19/167 (11%) vs. 7/166 (4%), P = 0.014; at week 96: 27/158 (17%) vs. 13/159 (8%), P =  0.019)]. Drug resistance mutations to NNRTI were detected in 19 out of 22 (86.3%) and dual-class resistance to nucleoside reverse transcriptase inhibitor (NRTI) and NNRTI in 15 out of 27 (68.2%) of NVP failing patients. K65R mutation was present in seven out of 14 patients failing NVP-TDF/FTC regimen. No major protease inhibitor-DRM was detected among LPV/r failing patients. Discontinuation for adverse events was similar between treatment groups. Conclusion: In resource-limited settings, first-line NNRTI-NRTI regimen as compared with bPI-based regimen provides similar outcome but is associated with a significantly higher number of virologic failure and resistance mutations in both classes that jeopardize future options for second-line therapy.

    2013-01-01

    Background Due to economic constraints, cancer therapies are under close scrutiny by clinicians, pharmacists and payers alike. There is no published pharmacoeconomic evidence guiding the choice of first-line therapy for advanced renal cell carcinoma (RCC) in the Spanish setting. We aimed to develop a model describing the natural history of RCC that can be used in healthcare decision-making. We particularly analyzed the budget impact associated with the introduction of pazopanib compared to sunitinib under the Spanish National Healthcare System (NHS) perspective. Methods We developed a Markov model to estimate the future number of cases of advanced RCC (patients with favorable or intermediate risk) resulting either from initial diagnosis or disease progression after surgery. The model parameters were obtained from the literature. We assumed that patients would receive either pazopanib or sunitinib as first-line therapy until disease progression. Pharmacological costs and costs associated with the management of adverse events (AE) were considered. A univariate sensitivity analysis was undertaken in order to test the robustness of the results. Results The model predicted an adult RCC prevalence of 7.5/100,000 (1-year), 20.7/100,000 (3-year) and 32.5/100,000 (5-year). These figures are very close to GLOBOCAN reported RCC prevalence estimates of 7.6/100,000, 20.2/100,000 and 31.1/100,000, respectively. The model predicts 1,591 advanced RCC patients with favorable or intermediate risk in Spain in 2013. Annual per patient pharmacological costs were €32,365 and €39,232 with pazopanib and sunitinib, respectively. Annual costs associated with the management of AE were €662 and €974, respectively. Overall annual per patient costs were €7,179 (18%) lower with pazopanib compared to sunitinib. For every point increase in the percentage of patients treated with pazopanib, the NHS would save €67,236. If all the 1,591 patients predicted were treated with pazopanib, the

    Since 1979, the International Organization for Migration has provided tuberculosis screening and treatment for those who intend to migrate from Viet Nam--a country with one of the highest tuberculosis incidence rates. The factors associated with non-response to first-line tuberculosis treatment were investigated in a comparative study of 130 non-responders (cases) and 673 responders (controls). Cases had worse radiologic signs and greater numbers of acid-fast bacilli on their sputum smears than controls. When these two factors were used as a diagnostic test to predict non-response, the model had a sensitivity of 70% and a specificity of 80%. Sensitivity increased to 80% when variables measured in the first 3 months of treatment were used. Failure to respond to treatment can be a result of infection with other mycobacteria, infection with a multi-drug resistant tuberculosis strain, or acquisition of resistance after the initiation of therapy. Further analysis of the same database is underway to determine the natural history and success of second-line treatment. PMID:9363535

    2016-01-01

    Background Splenic marginal zone lymphoma (SMZL) is a chronic B-cell lymphoproliferative disorder, comprising less than 2% of non-Hodgkin’s lymphomas, and affecting mainly middle-aged and elderly patients with a median survival of >10 years. The typical clinical features of SMZL include splenomegaly. Treatment should be patient-tailored and can range from a ‘watchful waiting’ approach for asymptomatic patients without cytopenias to surgery, localized radiation therapy or immuno/chemotherapies. Recently, the combination of rituximab and Bendamustine (R-Benda) has been defined as highly active in patients with follicular lymphomas, but little is known about the efficacy of R-Benda in SMZL. Aim of the study The purpose of this retrospective study was to report our experience on the efficacy of R-Benda as first line treatment in 23 consecutive elderly SMZL patients. Results All patients had a complete resolution of splenomegaly along with restoration of their blood counts. Nineteen patients (83%) achieved a complete response (CR) to therapy; three patients (13%) achieved a partial response (PR).Ten patients (43%) obtained molecular remission. Toxicities were mild and mainly haematological and result in dose reductions for fourteen patients. Conclusions Our data suggest a high activity and good tolerance of R-Benda, despite dose reduction due to potential toxicity. PMID:27413523

    Targeted therapies against EGFR, vascular endothelial growth factor, and vascular endothelial growth factor receptor have expanded treatment options for patients with metastatic colorectal cancer (mCRC). Unfortunately, biomarkers to identify patients that are most likely to derive benefit from targeted therapies in this disease are still needed. Indeed, only RAS mutations have been identified as predictive of lack of benefit from monoclonal antibodies against EGFR in patients with mCRC. Panitumumab is a fully humanized monoclonal antibody against EGFR. In this study, we review data to support the use of panitumumab in combination with a chemotherapy backbone, in the first line setting in patients with RAS wild-type mCRC. Ongoing efforts are aimed at identifying smaller subsets of patients within the RAS wild-type group that will derive the largest benefit from anti-EGFR therapy. In the meantime, treatment with anti-EGFR therapy should be reserved for patients with RAS wild-type mCRC. PMID:26770060

    Abstract We sought to develop individual-level Early Warning Indicators (EWI) of virologic failure (VF) for clinicians to use during routine care complementing WHO population-level EWI. A case-control study was conducted at a Durban clinic. Patients after≥5 months of first-line antiretroviral therapy (ART) were defined as cases if they had VF [HIV-1 viral load (VL)>1000 copies/mL] and controls (2:1) if they had VL≤1000 copies/mL. Pharmacy refills and pill counts were used as adherence measures. Participants responded to a questionnaire including validated psychosocial and symptom scales. Data were also collected from the medical record. Multivariable logistic regression models of VF included factors associated with VF (p<0.05) in univariable analyses. We enrolled 158 cases and 300 controls. In the final multivariable model, male gender, not having an active religious faith, practicing unsafe sex, having a family member with HIV, not being pleased with the clinic experience, symptoms of depression, fatigue, or rash, low CD4 counts, family recommending HIV care, and using a TV/radio as ART reminders (compared to mobile phones) were associated with VF independent of adherence measures. In this setting, we identified several key individual-level EWI associated with VF including novel psychosocial factors independent of adherence measures. PMID:24320011

    Idiopathic epilepsy (IE) is a common chronic neurological disease of the dog. Previous studies of anti-epileptic drug (AED) treatment have indicated that acceptable AED adverse effects are as important to owners as reductions in seizure frequency. AEDs in both dogs and human beings are frequently associated with the adverse-effect ataxia. The aim of this study was to compare ataxia levels in dogs with IE treated chronically with phenobarbitone or imepitoin, the two currently available first-line AED treatments. The gait of 6 imepitoin-treated dogs, 8 phenobarbitone-treated dogs and 10 age-matched healthy control dogs were compared. Fifty strides from a walking gait were analysed for each dog, quantifying ataxia via the variability in six established gait parameters. Three variables differed significantly between groups: lateral distance between (i) pelvic paw placements, (ii) thoracic paw placements and (iii) stance time, which were significantly more variable in the phenobarbitone-treated dogs than imepitoin-treated or control dogs. These results indicate that dogs treated with phenobarbitone experience ataxia compared with controls and imepitoin-treated dogs. Conversely, there was no difference between imepitoin-treated dogs and controls. These results along with further research are needed to quantify AEDs adverse effects, to help vets and owners make more informed drug-choices. PMID:27302918

    Pertuzumab (Perjeta®) is a humanized anti-HER2 monoclonal antibody that binds to the extracellular dimerization subdomain of the HER2 receptor and reduces HER2 intracellular signalling by preventing HER2 from forming heterodimers with other HER receptors. Inhibition of HER2 signalling results in a reduction of tumour cell proliferation, invasiveness and survival. Pertuzumab and trastuzumab bind to different sites on the HER2 receptor and have complementary antitumour activities; they act synergistically in inhibiting the growth of HER2-overexpressing breast cancer cell lines in vitro. The efficacy of intravenous pertuzumab (840 mg loading dose, then 420 mg every 3 weeks) in combination with trastuzumab plus docetaxel in the first-line treatment of HER2-positive metastatic breast cancer was demonstrated in the randomized, double-blind, placebo-controlled, multinational, phase III CLEOPATRA trial. Pertuzumab in combination with trastuzumab and docetaxel significantly increased independently assessed median progression-free survival (primary endpoint), objective response rate and overall survival compared with placebo in combination with trastuzumab and docetaxel. Pertuzumab had an acceptable tolerability profile when added to trastuzumab and docetaxel in the pivotal CLEOPATRA trial. Thus, pertuzumab is a valuable addition to the growing list of anti-HER2 targeted therapies for breast cancer. PMID:23982598

    At the present time, there are no proven beneficial effects of chemotherapy (CT) for the treatment of pure low-grade astrocytomas. Brain radiotherapy (RT) still remains the standard treatment in order to reduce or delay tumor progression or symptoms, despite possible long-term neurologic complications. We report 10 patients, with histologically proven pure low-grade fibrillary astrocytomas, to which we administered a first-line nitrosourea-based CT. All patients were symptomatic with pharmaco-resistant epilepsy or neurologic symptoms, and had been rejected for neurosurgical resection. All patients with epilepsy had a clinical improvement with reduction in seizure frequency and 60% became seizure-free. CT was well tolerated; all patients developed myelosuppression with 40% of grade III/IV hematotoxicity. Seven were alive at the time of writing with a mean follow-up of 6.5 years (3.5-12) from first recorded symptoms. The three deceased patients died 7.5, 7.5, and 8.5 years from first symptoms. These results demonstrate that some patients with symptomatic non-resectable fibrillary low-grade astrocytomas can be treated with up-front CT to improve their neurologic status. This report suggests that benefits of CT on symptoms, survival, and quality of life should be prospectively compared with RT. PMID:16128869

    Background Platinum-doublet, first-line treatment of locally advanced or metastatic non-small cell lung cancer (NSCLC) is limited to 4–6 cycles. An alternative strategy used to prolong the duration of first-line treatment and extend survival in metastatic NSCLC is first-line maintenance therapy. Erlotinib was approved for first-line maintenance in a stable disease population following results from a randomized, controlled Phase III trial comparing erlotinib with best supportive care. We aimed to estimate the incremental cost-effectiveness of erlotinib 150 mg/day versus best supportive care when used as first-line maintenance therapy for patients with locally advanced or metastatic NSCLC and stable disease. Methods An economic decision model was developed using patient-level data for progression-free survival and overall survival from the SATURN (SequentiAl Tarceva in UnResectable NSCLC) study. An area under the curve model was developed; all patients entered the model in the progression-free survival health state and, after each month, moved to progression or death. A time horizon of 5 years was used. The model was conducted from the perspective of national health care payers in France, Germany, and Italy. Probabilistic sensitivity analyses were performed. Results Treatment with erlotinib in first-line maintenance resulted in a mean life expectancy of 1.39 years in all countries, compared with a mean 1.11 years with best supportive care, which represents 0.28 life-years (3.4 life-months) gained with erlotinib versus best supportive care. In the base-case analysis, the cost per life-year gained was €39,783, €46,931, and €27,885 in France, Germany, and Italy, respectively. Conclusion Erlotinib is a cost-effective treatment option when used as first-line maintenance therapy for locally advanced or metastatic NSCLC. PMID:22347803

    To assess the effects of non-steroidal antiandrogen monotherapy compared with luteinizing hormone-releasing hormone agonists or surgical castration monotherapy for treating advanced hormone-sensitive stages of prostate cancer. We searched the Cochrane Prostatic Diseases and Urologic Cancers Group Specialized Register (PROSTATE), the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, EMBASE, Web of Science with Conference Proceedings, three trial registries and abstracts from three major conferences to 23 December 2013, together with reference lists, and contacted selected experts in the field and manufacturers. We included randomized controlled trials comparing non-steroidal antiandrogen monotherapy with medical or surgical castration monotherapy for men in advanced hormone-sensitive stages of prostate cancer. Two review authors independently examined full-text reports, identified relevant studies, assessed the eligibility of studies for inclusion, extracted data and assessed risk of bias as well as quality of evidence according to the GRADE working group guidelines. We used Review Manager 5.2 for data synthesis and the fixed-effect model as primary analysis (when heterogeneity was low with I(2) < 50%); we used a random-effects model when confronted with substantial or considerable heterogeneity (when I(2) ≥50%). A total of 11 studies involving 3060 randomly assigned participants were included in the present review. Use of non-steroidal antiandrogens resulted in lower overall survival times (hazard ratio [HR] 1.24, 95% confidence interval [CI] 1.05-1.48, six studies, 2712 participants) and greater clinical progression (1 year: risk ratio [RR] 1.25, 95% CI 1.08-1.45, five studies, 2067 participants; 70 weeks: RR 1.26, 95% CI 1.08-1.45, six studies, 2373 participants; 2 years: RR 1.14, 95% CI 1.04-1.25, three studies, 1336 participants), as well as treatment failure (1 year: RR 1.19, 95% CI 1.02-1.38, four studies, 1539 participants; 70 weeks: RR 1

    2006-10-01

    Anxiety disorders in the United States are prevalent, widespread, and disabling. These illnesses may account for almost one third of the $148 billion total mental health bill each year. Pharmacologic options include tricyclic antidepressants, monoamine oxidase inhibitors, serotonin norepinephrine reuptake inhibitors, selective serotonin reuptake inhibitors, and anxiolytics. Psychological treatments include cognitive-behavioral therapy (CBT), cognitive therapy, exposure, and ritual prevention therapies. Despite insufficient evidence, many experts recommend combined treatment, generally medication with CBT. A literature review was conducted to examine studies with random assignment, adequate methods and sample sizes, blind assessments, sufficient dosages and durations of treatment, and satisfactory reporting of data, to determine whether combined treatment was superior to monotherapy. Twenty-six randomized clinical trials were identified; nine met review criteria. A review of relevant studies could not confirm the superiority of combined treatment over monotherapy. In one of four studies of obsessive-compulsive disorder, combined treatment produced better results than monotherapy. There was no evidence of superiority for combined therapy over monotherapy for the treatment of social phobia or generalized anxiety disorder. There were no studies that met review criteria for either specific phobia or posttraumatic stress disorder (PTSD). With panic disorder, there was evidence that combined treatment might actually lead to worse outcome. Combined treatment is commonly recommended, but empirical support is limited. More research is needed. There are few well-designed studies, and little data regarding PTSD and specific phobias. PMID:17008828

    The use of combination therapy with mood stabilizers and antipsychotics in acute mania in bipolar disorder (BD) is widespread, although most treatment guidelines recommend monotherapy as the first option, and reserve combination therapy, which is associated with more frequent and more severe side effects, for when patients do not respond to the former treatment option. Reasons to prescribe combination therapy include the lack of efficacy of the current treatment (either real or due to undisclosed poor adherence), psychiatric comorbidities, severe previous course of illness, slow cross-tapering during treatment switching, and potential benefits from particular combinations. The decision to start with monotherapy or combination therapy may depend on the patient characteristics, and is still under debate. Clinical trials designed to ascertain whether combination therapy or monotherapy is more advantageous for patients in acute mania and beyond, according to illness severity, are urgently needed. Adding a third monotherapy arm to the conventional two-arm, adjunctive-design trials or initiating combination therapy from the beginning may help to shed some light on the issue. PMID:25711483

    FOLFIRINOX is a standard first-line treatment for advanced pancreatic cancer (aPC). The Gruppo Oncologico Nord Ovest (GONO) FOLFOXIRI regimen demonstrated efficacy in metastatic colorectal cancer. We aimed to evaluate activity and tolerability of FOLFOXIRI regimen in patients with aPC and to explore putative prognostic factors. One hundred thirty-seven consecutive aPC patients were treated with FOLFOXIRI in our institution between 2008 and 2014. Clinical, laboratory and pathological data were collected and their association with activity, progression free survival (PFS) and overall survival (OS) was investigated. After a median follow up of 30 months, median PFS and OS were 8.0 months (95% CI 6.19-9.81) and 12 months (95% CI 9.75-14.25), respectively. Response rate was 38.6%, while disease-control rate 72.2%. At multivariate analysis liver metastases (p = 0.019; Hazard Ratio, HR, 0.59, 95% Confidence Interval, CI, 0.380.96), Eastern Cooperative Oncology Group (ECOG) performance status (PS) 1 (p = 0.001; HR 2.26, 95%CI 1.42-3.59) and neutrophil-lymphocyte ratio (NLR)> 4 (p= 0.002; HR: 2.42; 95% CI 1.38-4.25) were associated with poorer OS. We categorized 119 pts with complete available data as good-risk (0 factors, 38 pts), intermediate-risk (1 factor, 49 pts) and poor-risk (≥2 factors, 32 pts). Median OS for these three groups were 17.6, 11.1 and 7.4 months, respectively (p < 0.001). FOLFOXIRI is active and feasible in aPC. Prognosis of aPC pts treated with FOLFOXIRI is influenced by easily available factors: our analysis revealed ECOG PS, liver metastases and NLR as the most important predictors of survival. These factors could be helpful for treatment decision and clinical trial design. PMID:27038273

    Background/Aims To evaluate the adjuvant effects of N-acetylcysteine (NAC) on first-line sequential therapy (SQT) for Helicobacter pylori infection. Methods Patients with H. pylori infections were randomly assigned to receive sequential therapy with (SQT+NAC group, n=49) or without (SQT-only group, n=50) NAC. Sequential therapy consisted of rabeprazole 20 mg and amoxicillin 1 g for the first 5 days, followed by rabeprazole 20 mg, clarithromycin 500 mg and metronidazole 500 mg for the remaining 5 days; all drugs were administered twice daily. For the SQT+NAC group, NAC 400 mg bid was added for the first 5 days of sequential therapy. H. pylori eradication was evaluated 4 weeks after the completion of therapy. Results The eradication rates by intention-to-treat analysis were 58.0% in the SQT-only group and 67.3% in the SQT+NAC group (p=0.336). The eradication rates by per-protocol analysis were 70.0% in the SQT-only group and 80.5% in the SQT+NAC group (p=0.274). Compliance was very good in both groups (SQT only/SQT+NAC groups: 95.2%/100%, p=0.494). There was no significant difference in the adverse event rates between groups (SQT-only/SQT+NAC groups: 26.2%/26.8%, p=0.947). Conclusions The H. pylori eradication rate was numerically higher in the SQT+NAC group than in the SQT-only group. As our data did not reach statistical significance, larger trials are warranted.

    Background HIV-1 viral load (VL) testing is recommended to monitor antiretroviral therapy (ART) but not universally available. We examined monitoring of first-line and switching to second-line ART in sub-Saharan Africa, 2004–2013. Methods Adult HIV-1 infected patients starting combination ART in 16 countries were included. Switching was defined as a change from a non-nucleoside reverse-transcriptase inhibitor (NNRTI)-based regimen to a protease inhibitor (PI)-based regimen, with a change of ≥1 NRTI. Virological and immunological failures were defined per World Health Organization criteria. We calculated cumulative probabilities of switching and hazard ratios with 95% confidence intervals (CI) comparing routine VL monitoring, targeted VL monitoring, CD4 cell monitoring and clinical monitoring, adjusted for programme and individual characteristics. Findings Of 297,825 eligible patients, 10,352 patients (3·5%) switched during 782,412 person-years of follow-up. Compared to CD4 monitoring hazard ratios for switching were 3·15 (95% CI 2·92–3·40) for routine VL, 1·21 (1·13–1·30) for targeted VL and 0·49 (0·43–0·56) for clinical monitoring. Overall 58.0% of patients with confirmed virological and 19·3% of patients with confirmed immunological failure switched within 2 years. Among patients who switched the percentage with evidence of treatment failure based on a single CD4 or VL measurement ranged from 32·1% with clinical to 84.3% with targeted VL monitoring. Median CD4 counts at switching were 215 cells/µl under routine VL monitoring but lower with other monitoring (114–133 cells/µl). Interpretation Overall few patients switched to second-line ART and switching occurred late in the absence of routine viral load monitoring. Switching was more common and occurred earlier with targeted or routine viral load testing. PMID:26423252

    AIM: To determine if dopamine is effective in treating neonatal hypotension and safe to use comparing to other inotropes. METHODS: This is a review of evidence on inotropic treatment of neonatal hypotension. Databases searched were MEDLINE and the Cochrane Library, a total of 134 studies were identified. Only studies with high quality evidence (level 1a and b and 2a) were included. After review, only eight studies were included in the final analysis. Pooled risk ratios derived for each outcome [Mantel-Haenzel (M-H) fixed effect] with CI, as reported in the Cochrane reviews were plotted in forest plot form. RESULTS: Eight articles met inclusion criteria, which all included treatment in preterm infants. Dopamine increased mean arterial blood pressure (BP) (n = 163; r = 0.88, 95%CI: 0.76 to 0.94) and systolic BP (n = 142; r = 0.81, 95%CI: 0.42 to 0.94) comparing to placebo. Dopamine has been shown overall to be statistically more effective in increasing BP than dobutamine (n = 251, r = 0.26, 95%CI: 0.20-0.32). However there were no differences in short term outcomes (periventricular leucomalacia, periventricular haemorrhage) and mortality between both drugs. There is no statistical evidence of dopamine being more effective than adrenaline or corticosteroids. There was no difference in morbidity and mortality outcomes when dopamine was compared to hydrocortisone (RR 1.81, 95%CI: 0.18 to 18.39) or adrenaline. CONCLUSION: In preterms, dopamine is the most studied drug, and we suggest it could be used as first line treatment in hypotension. PMID:27170932

    Objective There are limited data on treatment-related anemia in Asian HIV-infected children. Methods Data from Asian HIV-infected children aged <18 years on first-line highly active antiretroviral therapy (HAART) were used. Children who had preexisting severe anemia at baseline were excluded. Anemia was graded by using the DAIDS 2004 table. Potential risk factors of severe anemia were assessed by logistic regression. Results Data from 1,648 children (51.9% female, 62.8% WHO stage 3/4) were analyzed. Median (IQR) age was 6.8 (3.7–9.6) years, CD4% was 9 (3–16)% and plasma HIV-RNA was 5.2 (4.7–5.6) log10 copies/ml at HAART initiation in those with available testing. The most common regimens were stavudine/lamivudine/nevirapine (42%) and zidovudine/lamivudine/nevirapine (25%). Severe anemia was identified in 47 (2.9%) children after a median time of 6 months after HAART initiation with an incidence rate of 5.4 per 100 child-years. Mild anemia or moderate anemia at baseline (p=0.024 and p=0.005, respectively), previous or current use of zidovudine (p<0.0001 and p=0.013, respectively), and male sex (p=0.008) were associated with severe anemia. Higher weight-for-age z-score (p=0.004) was protective. Conclusions The incidence of severe anemia in Asian HIV-infected children after HAART initiation was low and mainly occurred during the first few months after HAART initiation. Mild to moderate anemia at baseline and using AZT were independent risk factors of developing severe anemia. PMID:23764352

    This study assessed second-line continued use of cetuximab for treatment of unresectable metastatic colorectal cancer (mCRC) after disease progression during first-line cetuximab-based therapy. Consecutive patients with wild-type KRAS exon 2 and unresectable mCRC were retrospectively enrolled after disease progression during first-line cetuximab-based chemotherapy. Second-line continued cetuximab plus changed chemotherapy (cetuximab continuation group, n = 102) was compared with changed chemotherapy only (chemotherapy only group, n = 96) with respect to treatment efficacy and safety endpoints. NRAS and other KRAS genotypes were also detected as a post hoc analysis. The cetuximab continuation group showed better progression-free survival (median, 6.3 vs. 4.5 months, P = 0.004), overall survival (median, 17.3 vs. 14.0 months, P < 0.001) and disease control rate (70.6% vs. 53.1%, P = 0.011), and a potentially better overall response rate (18.6% vs. 9.4%, P = 0.062) than the chemotherapy only group. These benefits were seen mainly in patients with all RAS wild-type and exhibiting first-line early tumor shrinkage (ETS). For patients with other RAS mutations or who did not achieve first-line ETS, there was no difference between the two groups. These findings suggest that for patients with all RAS wild-type and unresectable mCRC who had disease progression during first-line cetuximab-based treatment, second-line continued cetuximab is effective. Moreover, ETS during first-line cetuximab-based treatment may be predictive of the efficacy of second-line continued cetuximab. PMID:26863631

    Background To investigate the value of the metabolic tumor response assessed with 18F-fluorodeoxyglucose positron emission tomography (FDG-PET), compared with clinicobiological markers, to predict the response disease to first line platinum based chemotherapy in advanced thymic epithelial tumors (TETs). Methods Twenty patients with diagnosis of TET and stage of disease III and IV sec, Masaoka-Koga, were retrospectively included in this monocentric study. Different pre-treatment clinical, biological and pathological parameters, including histotype sec, WHO 2004 and stage of disease sec, Masaoka-Koga were assessed. Tumor glucose metabolism at baseline and its change after the first line platinum based chemotherapy (from 4 to 6 cycles) were assessed using FDG-PET, moreover the response disease was assessed using total body CT scan for the evaluation of RECIST criteria 1.1. Results Twelve patients had an objective response to the first line platinum based chemotherapy according RECIST criteria 1.1 and all of them started with a SUVmax at baseline major than 5, indeed the other eight patients, non-responders to chemotherapy, had a SUVmax at baseline minor than 5. Conclusions It is important to define the chemosensitivity of advanced TETs early. Combining bio-pathological parameters with the metabolism at baseline assessed with FDG-PET can help the physician to early predict the probability of obtaining a disease response to first line platinum based chemotherapy. The SUVmax cut off of 5 at 18FDG-PET/CT performed at baseline treatment might be a new parameter for choosing the most powerful first line of chemotherapy. Given these results, further prospective studies are needed to establish a new first line therapy in advanced TETs with a low SUVmax at baseline, non-responders to conventional chemotherapy.

    This article examines the role characteristics, responsibilities, and anticipated career patterns of first-line nurse administrators employed in university-based nursing education programs throughout the nation. First-line administration is the first level on the administrative ladder, and these administrators are most frequently entitled department chairpersons; division, program, and level directors; or coordinators. This was an exploratory and descriptive research project, and the questions addressed were (1) How are first-line nurse administrators in academe formally educated and informally prepared for their administrative role? (2) What are the administrative competencies important for this administrative role? (3) What strains, conflicts, and work overload are associated with the first-line administrative role, and what strategies are used to cope? (4) What do these administrators anticipate as a career pattern in administration based on their experiences as first-line administrators? Fifty-six first-line nurse administrators were interviewed from 42 schools of nursing that offer both bachelor's degree and graduate nursing programs. Data indicated that one third of the study participants completed graduate level courses in administration, and the majority had worked with administrative mentors. They ranked having character and integrity as their most important competency, which was defined as being trusted by faculty, other administrators, and students. Settling priorities for their administrative work caused them their greatest strain, and work overload was most predominant. Role conflict was present consistently as they attempted to meet the traditional triad of faculty responsibilities (research and scholarship, teaching, service) plus administrative duties. Numerous time-management strategies were used to cope, but nonetheless, one half will not continue in an administration career pathway. Implications for academic nurse administrators are cited. PMID

    According to the published report on current practice of hematopoietic SCT in Europe, high-dose therapy (HDT) with autologous stem cell support is a standard of care in paediatric patients with high risk (HR) or relapsed Ewing's sarcoma (ES). Randomized trials, however, have not confirmed the value of this procedure yet. In this retrospective analysis we intended to evaluate the role of HDT as a consolidation therapy in first remission of ES. A total of 102 patients were included in the analysis and divided according to the following risk factors: metastatic disease at presentation, feasibility of surgery and histological response after induction. Forty-one patients were classified as standard risk (SR) patients, while the remaining 61 children, with at least one risk factor, were classified as HR patients. HR group patients were non-randomized and qualified according to the decision of the local clinician to give a conventional consolidation (CC) or to perform high-dose chemotherapy and radiotherapy in selected patients. Twenty-six children were given CC while 35 patients were treated with HDT. The HDT consisted of oral BU 4 mg/kg p.o. in divided doses daily for 4 days (total dose 16 mg/kg) followed by melphalan 140 mg/m(2) i.v. on day -2. Probability of relapse-free survival (RFS) in median observation time was significantly worse in HR patients who were given CC therapy as compared with children with HR features receiving high-dose chemotherapy (0.27 vs 0.66 (P = 0.008); OS 0.31 vs 0.71 (P = 0.007), respectively). Patients from the SR group had a probability of RFS of 0.72 and OS of 0.75, and the difference between SR and HR patients after HDT was NS (P = 0.37). Our observation confirms that the consolidation of the first-line treatment with BU and melphalan improves the outcome in ES patients with HR features. PMID:22609883

    Thirty-two women with untreated metastatic breast cancer were treated with 100 mg/M2 i.v. methotrexate (MTX), 600 mg/M2 5-fluorouracil (5FU) and leucovorin 15 mg orally every 6 hr, 24 hr after MTX (MFL) on days 1 and 8 every 28 days. Stratification was according to sites of metastases (mets), adjuvant (adj), chemotherapy (CTX), and/or hormonal therapy or no adj therapy (Tx). Treatment continued until documented radiographic or clinical disease was in progression. Toxicity was mild, consisting of only minimal elevations of transaminases and mild cytopenias. There was no pulmonary toxicity. There were no hospitalizations, treatment delays or cessations for toxicity. One patient with skeletal mets had a complete response and 7 had partial responses. The overall median progression free survival (PFS) was 13.8 months (mos). Eighteen patients with skeletal mets had PFS from 7-70 mos (median 15.9). Five patients with lung mets only had PFS from 6-20 mos (median 9.8 mos). Patients with liver alone or with other visceral mets showed progression within 2-5 mos. However, patients with bone and visceral mets without liver involvement had PFS from 8-50 mos (median 20.5). Of 21 adj Tx failures the median PFS was 8.8 mos (2-94). Six who received adj CTX had a median PFS of 7.6 mos (3-12) and 4 tamoxifen (tam) failures a median PFS of 11 mos (8-15). Eleven patients who received adj CTX+tam had a median PFS of 8.5 mos (2-94). Six patients received tam at adj failure and MFL at progression. These six had a median PFS of 19.8 mos (8-50). The patients (six, who received no prior adj Tx) had a median PFS of 24.3 (8-70). MFL is as effective in achieving clinical remissions in metastatic breast cancer, is inexpensive and is far less toxic than other CTX regimes. MFL should strongly be considered as first line Tx.

    Background We performed an updated meta-analysis of randomized placebo-controlled trials testing memantine monotherapy for patients with Alzheimer’s disease (AD). Methods The meta-analysis included randomized controlled trials of memantine monotherapy for AD, omitting those in which patients were also administered a cholinesterase inhibitor. Cognitive function, activities of daily living, behavioral disturbances, global function, stage of dementia, drug discontinuation rate, and individual side effects were compared between memantine monotherapy and placebo groups. The primary outcomes were cognitive function and behavioral disturbances; the others were secondary outcomes. Results Nine studies including 2433 patients that met the study’s inclusion criteria were identified. Memantine monotherapy significantly improved cognitive function [standardized mean difference (SMD)=−0.27, 95% confidence interval (CI)=−0.39 to −0.14, p=0.0001], behavioral disturbances (SMD=−0.12, 95% CI=−0.22 to −0.01, p=0.03), activities of daily living (SMD=−0.09, 95% CI=−0.19 to −0.00, p=0.05), global function assessment (SMD=−0.18, 95% CI=−0.27 to −0.09, p=0.0001), and stage of dementia (SMD=−0.23, 95% CI=−0.33 to −0.12, p=0.0001) scores. Memantine was superior to placebo in terms of discontinuation because of inefficacy [risk ratio (RR)=0.36, 95% CI=0.17¬ to 0.74, p=0.006, number needed to harm (NNH)=non significant]. Moreover, memantine was associated with less agitation compared with placebo (RR=0.68, 95% CI=0.49 to 0.94, p=0.02, NNH=non significant). There were no significant differences in the rate of discontinuation because of all causes, all adverse events, and individual side effects other than agitation between the memantine monotherapy and placebo groups. Conclusions Memantine monotherapy improved cognition, behavior, activities of daily living, global function, and stage of dementia and was well-tolerated by AD patients. However, the effect

    Thalidomide-dexamethasone therapy was given in patients (<61 years) with previously untreated symptomatic multiple myeloma. The aim of this study was to assess the efficacy and toxicity of this combination as first-line therapy, and to determine its effect on stem cell collection and engraftment. During first-line therapy, thalidomide and dexamethasone were administered for 75 days (200 mg/day) and 3 months, respectively. The monthly dose of dexamethasone was 20 mg/m2/day for 4 days, with cycles repeated on days 9 to 12 and 17 to 20 on the first and the third month of therapy. After first-line therapy, a collection of peripheral blood stem cells (PBSC) was performed. Between May 2003 and September 2004, 60 patients were included. On an intent-to-treat basis, the overall response (> or =partial response) rate was 74%, including 24% of patients who obtained a complete remission. Grade 3-4 toxicities consisted of infections (12%), deep-vein thrombosis (3%), constipation (5%), and neuropathy (5%). A total of 58 patients (96%) proceeded to PBSC mobilisation and yielded a median number of 8 x 10(6) CD34+ cells/kg. First-line thalidomide-dexamethasone therapy is effective and relatively well tolerated in young patients with symptomatic multiple myeloma. This combination does not affect PBSC mobilisation.

    Gemcitabine, a pyrimidine nucleoside analogue, is gaining recognition as a potential therapeutic agent for advanced-stage and refractory cutaneous T-cell lymphoma (CTCL). We report of 2 patients whose advanced-stage mycosis fungoides was not sufficiently controlled by prior CHOP therapy. Both patients showed great improvement in the skin lesions with weekly gemcitabine therapy (1,000-1,200 mg/m2). The patients received four and 8 cycles of gemcitabine monotherapy, respectively, and no grade 3-4 hematological or hepatic adverse events occurred. This is the first report of the efficacy of gemcitabine for CTCL in Japan. Gemcitabine is well tolerated and is an effective monotherapy for CTCL. PMID:26809303

    Pregnancy outcomes in patients with pulmonary arterial hypertension have not been documented in our local setting. In our institution, access to therapies like nitric oxide, inhaled prostacyclin and iloprost is limited. We describe two such women given sildenafil monotherapy between April and May 2011. Both had an atrial septal defect complicated by Eisenmenger syndrome. Both survived – one after elective Caesarean section for malpresentation (breech) under general anaesthesia, the other after an assisted vaginal delivery. In addition to oral sildenafil, both received oxygen supplementation. To date, there have been three reported cases of pulmonary arterial hypertension in pregnancy treated with sildenafil in combination with another drug. Our two cases demonstrate that treatment for pulmonary arterial hypertension using sildenafil as monotherapy may allow stabilization of the maternal condition and improve clinical outcomes for both mother and baby. However, pregnancy is still discouraged in women with pulmonary arterial hypertension.

    Cancer in transplant recipients represents a therapeutic challenge even when the patient is already under mTOR inhibitors. A 78-year-old man received a deceased donor kidney transplant in 1993. After 6 months, he developed a multifocal cutaneous and nonvisceral Kaposi's Sarcoma while on cyclosporine immunosuppressant therapy. The patient was converted to sirolimus monotherapy in 2001 with subsequent complete recovery within 2 years. In 2007, the patient was diagnosed with an esophageal adenocarcinoma stage IIA. An esophagectomy was performed without requirement of further treatment. He has continued on sirolimus monotherapy ever since, with no other incidents and no recurrences of either tumor. In this report, we describe an interesting case of a second cancer while on immunosuppressive therapy with anticancer activity. Moreover, the present knowledge of the matter is discussed.

    A 63-year-old woman underwent a low anterior resection for rectal cancer in 2002.A n anastomotic recurrence was diagnosed in July 2011.S he rejected the possibility of colostomy as radical surgery.Chemotherapy consisting of capecitabine+ oxaliplatin (XELOX) or folinic acid, fluorouracil, and oxaliplatin (FOLFOX6) + bevacizumab were not possible because of high costs. In view of the lower costs and the potential for ambulation, S-1 monotherapy was started. After 3 months, a reduction in the recurrent lesion was observed.After 19 months, the recurrent lesion revealed a scar, which was judged by biopsy to be Group 1.We had achieved a pathological complete response (CR).The standard treatment for recurrent colon cancer is surgical resection or multidrug chemotherapy. However, in view of a patient's quality of life (QOL), S-1 monotherapy may be considered as a potential therapy. PMID:25731306

    Objectives: The prevalence of obesity is rapidly increasing among Indian children, who, in general, are more prone to develop metabolic complications at an early age. Valproate and phenytoin are commonly used antiepileptic drugs in children. This study aimed to assess the parameters of the metabolic syndrome in Indian children with epilepsy on valproate or phenytoin monotherapy. Methods: This cross-sectional study recruited children from the Pediatric Epilepsy Clinic, Department of Pediatrics, Kalawati Saran Children Hospital, New Delhi from March 2012 to September 2012. All consecutive children diagnosed with epilepsy as per International League Against Epilepsy definition aged 3–18 years on valproate or phenytoin monotherapy for at least 6 months were enrolled at a tertiary care children's hospital in Northern India. After clinical and anthropometric evaluation (including body mass index [BMI] and waist circumference), the blood samples were analyzed for fasting serum glucose, total cholesterol, high-density lipoprotein-cholesterol, and serum triglyceride. Results: Children with BMI >95th centile and waist circumference >90th centile were not significantly different among children on valproate and phenytoin monotherapy. Children on valproate had significantly higher mean serum triglyceride (96.9 mg/dL vs. 77.6 mg/dL; P < 0.001) and total cholesterol (148.3 mg/dL vs. 132.8 mg/dL; P = 0.002) levels as compared to children on phenytoin monotherapy. Conclusions: The lipid abnormalities may be observed in children on valproate or phenytoin therapy and may warrant periodic screening. PMID:26557161

    Purpose: High-dose-rate (HDR) brachytherapy used as the only treatment (monotherapy) for early prostate cancer is consistent with current concepts in prostate radiobiology, and the dose is reliably delivered in a prospectively defined anatomic distribution that meets all the requirements for safe and effective therapy. We report the disease control and toxicity of HDR monotherapy from California Endocurietherapy (CET) and William Beaumont Hospital (WBH) in low- and intermediate-risk prostate cancer patients. Methods and Materials: There were 298 patients with localized prostate cancer treated with HDR monotherapy between 1996 and 2005. Two biologically equivalent hypofractionation protocols were used. At CET the dose was 42 Gy in six fractions (two implantations 1 week apart) delivered to a computed tomography-defined planning treatment volume. At WBH the dose was 38 Gy in four fractions (one implantation) based on intraoperative transrectal ultrasound real-time treatment planning. The bladder, urethral, and rectal dose constraints were similar. Toxicity was scored with the National Cancer Institute Common Toxicity Criteria for Adverse Events version 3. Results: The median follow-up time was 5.2 years. The median age of the patients was 63 years, and the median value of the pretreatment prostate-specific antigen was 6.0 ng/mL. The 8-year results were 99% local control, 97% biochemical control (nadir +2), 99% distant metastasis-free survival, 99% cause-specific survival, and 95% overall survival. Toxicity was scored per event, meaning that an individual patient with more than one symptom was represented repeatedly in the morbidity data table. Genitourinary toxicity consisted of 10% transient Grade 2 urinary frequency or urgency and 3% Grade 3 episode of urinary retention. Gastrointestinal toxicity was <1%. Conclusions: High disease control rates and low morbidity demonstrate that HDR monotherapy is safe and effective for patients with localized prostate cancer.

    Topical treatment with betamethasone butyrate propionate lotion on 37 patients with scalp psoriasis was replaced with a combination therapy using maxacalcitol lotion (on weekdays) and BBP (on the weekends). This combination therapy was later switched to MXA monotherapy. To identify the optimum duration of the combination therapy, the patients were divided into two groups: a 4-week group and an 8-week group, which were given combination therapy and monotherapy. In both groups, the total mean scores for the skin symptoms had significantly improved in comparison with that obtained at the outset of the study (p < 0.01). In terms of overall improvement, 20.0% of the 4-week group and 72.7% of the 8-week group yielded scores reflecting moderate or greater improvement. The treatment administered to the 8-week group was significantly more effective than that given to the 4-week group at the end of the trial (p < 0.01). This study also suggests that a 4-week combination therapy is an option before switching to monotherapy, but that an 8-week therapy is preferable in severe cases. PMID:22515652

    Background/Aims Angiotensin receptor blockers (ARBs) inhibit activated hepatic stellate cell contraction and are thought to reduce the dynamic portion of intrahepatic resistance. This study compared the effects of combined treatment using the ARB candesartan and propranolol versus propranolol monotherapy on portal pressure in patients with cirrhosis in a prospective, randomized controlled trial. Methods Between January 2008 and July 2009, 53 cirrhotic patients with clinically significant portal hypertension were randomized to receive either candesartan and propranolol combination therapy (26 patients) or propranolol monotherapy (27 patients). Before and 3 months after the administration of the planned medication, the hepatic venous pressure gradient (HVPG) was assessed in both groups. The dose of propranolol was subsequently increased from 20 mg bid until the target heart rate was reached, and the candesartan dose was fixed at 8 mg qd. The primary endpoint was the HVPG response rate; patients with an HVPG reduction of >20% of the baseline value or to <12 mmHg were defined as responders. Results The mean portal pressure declined significantly in both groups, from 16 mmHg (range, 12-28 mmHg) to 13.5 mmHg (range, 6-20 mmHg) in the combination group (P<0.05), and from 17 mmHg (range, 12-27 mmHg) to 14 mmHg (range, 7-25 mmHg) in the propranolol monotherapy group (P<0.05). However, the medication-induced pressure reduction did not differ significantly between the two groups [3.5 mmHg (range, -3-11 mmHg) vs. 3 mmHg (range, -8-10 mmHg), P=0.674]. The response rate (55.6% vs. 61.5%, P=0.435) and the reductions in mean blood pressure or heart rate also did not differ significantly between the combination and monotherapy groups. Conclusions The addition of candesartan (an ARB) to propranolol confers no benefit relative to classical propranolol monotherapy for the treatment of portal hypertension, and is thus not recommended.

    Objectives This purpose of this study was to examine clinical-pathologic factors – particularly smoking and brain metastases – in EGFR mutation positive (M+) lung adenocarcinoma (ADC) to determine their impact on survival in patients treated with first line EGFR TKI. Methods A retrospective review of EGFR mutation reflex testing experience for all ADC diagnosed at a tertiary Asian cancer centre from January 2009 to April 2013. Amongst this cohort, patients with advanced EGFR M+ ADC treated with first line EGFR TKI were identified to determine factors that influence progression free and overall survival. Results 444/742 (59.8%) ADC reflex tested for EGFR mutations were EGFR M+. Amongst never-smokers (n=468), EGFR M+ were found in 74.5% of females and 76.3% of males, and amongst ever smokers (n=283), in 53.3% of females and 35.6% of males. Exon 20 mutations were found more commonly amongst heavy smokers (> 50 pack years and > 20 pack years, Pearson’s chi square p=0.044, and p=0.038 respectively). 211 patients treated with palliative first line TKI had a median PFS and OS of 9.2 and 19.6 months respectively. 26% of patients had brain metastasis at diagnosis. This was significantly detrimental to overall survival (HR 1.85, CI 1.09-3.16, p=0.024) on multivariate analysis. There was no evidence that smoking status had a significant impact on survival. Conclusions The high prevalence of EGFR M+ in our patient population warrants reflex testing regardless of gender and smoking status. Smoking status and dosage did not impact progression free or overall survival in patients treated with first line EGFR TKI. The presence of brain metastasis at diagnosis negatively impacts overall survival. PMID:25955322

    Clinical trials exploring the long-term effects of first-line therapy in patients with advanced non-small-cell lung cancer generally disregard subsequent treatment although most patients receive second and third-line therapies. The choice of further therapy depends on critical intermediate events such as disease progression and it is usually left at the physician’s discretion. Time-dependent confounding may then arise with standard survival analyses producing biased effect estimates, even in randomized trials. Herein we describe the concept of time-dependent confounding in detail and discuss whether the response to first-line treatment may be a potential time-dependent confounding factor for survival in the context of subsequent therapy. A prospective observational study of 406 patients with advanced non-small-cell lung cancer served as an example base. There is evidence that time-dependent confounding may occur in multivariate survival analysis after first-line therapy when disregarding subsequent treatment. In the light of this important but underestimated aspect some of the large and meaningful recent clinical first-line lung cancer studies are discussed, focussing on subsequent treatment and its potential impact on the survival of the study patients. No recently performed lung cancer trial applied adequate statistical analyses despite the frequent use of subsequent therapies. In conclusion, effect estimates from standard survival analysis may be biased even in randomized controlled trials because of time-dependent confounding. To adequately assess treatment effects on long-term outcomes appropriate statistical analyses need to take subsequent treatment into account. PMID:22263071

    In a South African cohort of participants living with HIV developing virological failure on first-line tenofovir disoproxyl fumarate (TDF)-based regimens, at least 70% of participants demonstrated TDF resistance according to combined Sanger and MiSeq genotyping. Sanger sequencing missed the K65R mutation in 30% of samples. Unless HIV genotyping is available to closely monitor epidemiological HIV resistance to TDF, its efficacy as second-line therapy will be greatly compromised. PMID:26807968

    We carried out a meta-analysis to evaluate the benefit of epidermal growth factor-tyrosine kinase inhibitors (EGFR-TKI) over the standard first-line platinum-based chemotherapy for metastatic non-small-cell lung cancer (NSCLC). Studies that were considered eligible included controlled prospective randomized phase III studies in patients with NSCLC stages IIIB or IV. These patients received standard first-line platinum-based chemotherapy or EGFR-TKI; overall survival and progression-free survival (PFS) with adequate data were available to calculate and estimate the hazard ratio (HR) with a confidence interval (CI) of 95%. Eight studies were identified that compared EGFR-TKI versus standard first-line platinum-based chemotherapy to treat NSCLC in 2962 patients. Patients receiving EGFR-TKI showed significantly longer PFS [HR=0.266 (95% CI=0.20-0.35), P<0.0001]. No significant difference in overall survival [HR=0.946 (95% CI=0.35-2.53), P=0.912] was observed between the groups. The cumulative meta-analysis of the studies showed that, since 2011 (OPTIMAL study), the PFS benefit in the EGFR-TKI arm was statistically significantly longer. Toxicity values greater than or equal to 3 in the most prevalent EGFR-TKI group included skin rash, diarrhea, and increased aminotransferase. EGFR-TKI treatment significantly extends PFS, with acceptable toxicities than platinum-based chemotherapy. Thus, they should be considered as the first choice in the first-line treatment for patients with NSCLC and with the EGFR mutation. PMID:26237501

    Background. The evidence supporting the use of trastuzumab (T) in a metastatic setting comes from studies that included (almost) only patients who never received prior T. We investigated the effectiveness of T as first-line therapy for metastatic breast cancer (mBC) in women previously treated with T in the adjuvant setting. Materials and Methods. By using record linkage of five administrative health care databases of Lombardy, Italy, we identified 2,046 women treated with T for early breast cancer (eBC) in 2006–2009, 96 of whom developed a metastasis and were retreated with T in first-line treatment for mBC (treatment group). We compared the overall survival (OS) of these women with that of 197 women treated with T in first-line treatment for mBC, who were treated with therapies other than T for early disease (control group). We computed Kaplan-Meier 2-year OS and used a proportional hazard model to estimate the multivariate hazard ratio (HR) of death in the intervention group compared with the control group, adjusted by age, use of endocrine therapy, and site of metastasis. Results. Two-year OS was 60.0% in the treatment group and 59.5% in the control group. The adjusted HR of death in the treatment group compared with the control group was 0.79 (95% confidence interval, 0.50–1.26). Conclusion. Our data provide convincing evidence that the outcome of women receiving first-line T treatment for mBC after T failure in the adjuvant setting is comparable to that of women not receiving T for eBC. These data are of specific interest, given the unavailability of data from randomized clinical trials. PMID:25355843

    Colorectal cancer liver metastasis (CRLM) is a refractory disease after failure of first-line or second-line chemotherapy. Bevacizumab is recommended as first-line therapy for advanced colorectal cancer, but is unproven in CRLM through the hepatic artery. We report favorable outcomes with targeted vessel regional chemotherapy (TVRC) for liver metastatic gastric cancer. TVRC with FOLFOX and bevacizumab perfusion through the hepatic artery was attempted for CRLM for efficacy and safety evaluation. In a single-institution retrospective observational study, 246 patients with CRLM after at least first-line or second-line failure of systemic chemotherapy received TVRC with FOLFOX (i.e. oxaliplatin, leucovorin, and 5-fluorouracil). Of 246 patients, 63 were enrolled into two groups: group 1 (n=30) received bevacizumab and TVRC following tumor progression during previous TVRC treatments; group 2 (n=33) received TVRC plus bevacizumab for CRLM on initiating TVRC. There were no significant differences in the median survival time (14.7 vs. 13.2 months, P=0.367), although the median time to progression was significant (3.3 vs. 5.5 months, P=0.026) between groups. No severe adverse events related to TVRC plus bevacizumab perfusion occurred. Target vessel regional chemotherapy with FOLFOX plus bevacizumab perfusion through the hepatic artery was effective and safe in CRLM. The optimal combination of TVRC and bevacizumab needs further confirmation in future phase II-III clinical trials. PMID:26566233

    Background The World Health Organization Antiretroviral Treatment Guidelines recommend phasing-out stavudine because of its risk of long-term toxicity. There are two mutational pathways of stavudine resistance with different implications for zidovudine and tenofovir cross-resistance, the primary candidates for replacing stavudine. However, because resistance testing is rarely available in resource-limited settings, it is critical to identify the cross-resistance patterns associated with first-line stavudine failure. Methods We analyzed HIV-1 resistance mutations following first-line stavudine failure from 35 publications comprising 1,825 individuals. We also assessed the influence of concomitant nevirapine vs. efavirenz, therapy duration, and HIV-1 subtype on the proportions of mutations associated with zidovudine vs. tenofovir cross-resistance. Results Mutations with preferential zidovudine activity, K65R or K70E, occurred in 5.3% of individuals. Mutations with preferential tenofovir activity, ≥two thymidine analog mutations (TAMs) or Q151M, occurred in 22% of individuals. Nevirapine increased the risk of TAMs, K65R, and Q151M. Longer therapy increased the risk of TAMs and Q151M but not K65R. Subtype C and CRF01_AE increased the risk of K65R, but only CRF01_AE increased the risk of K65R without Q151M. Conclusions Regardless of concomitant nevirapine vs. efavirenz, therapy duration, or subtype, tenofovir was more likely than zidovudine to retain antiviral activity following first-line d4T therapy.

    Metastatic pancreatic cancer (PC) has been associated with a considerably poor prognosis. Due to its toxicity, first-line combination chemotherapy is limited to patients with a good performance status (PS). Previously nab-paclitaxel plus gemcitabine has been demonstrated to improve the overall survival rate in patients with advanced pancreatic cancer with a good PS. The present study reports a case of a patient with metastatic PC with a poor PS (Eastern Cooperative Oncology Group 2) and a complex set of comorbidities treated with nab-paclitaxel plus gemcitabine as a first-line palliative therapy. Adjusted doses of nab-paclitaxel plus gemcitabine reached a favourable clinical, radiological and biochemical response in the present patient, which increased the quality of life for the patient. Eventually, the patient succumbed to acute cholangitis. Based on the results of the present study, nab-paclitaxel plus gemcitabine appears to be a favourable treatment as first-line palliative chemotherapy for patients with metastatic PC, comorbidities and poor PS.

    The availability of tyrosine kinase inhibitors has extended therapeutic options for chronic myeloid leukaemia (CML) patients. Monitoring recommendations and clinical response goals have recently been updated. The objective of this study was to describe the profile of CML patients in chronic phase currently receiving first-line therapy, including treatment, monitoring and response kinetics. A multicentre, cross-sectional, epidemiological survey in unselected chronic phase CML patients in France attending consultations during a one-month period was performed. 438 of 697 (62·8%) reported patients were currently receiving first-line treatment and were analysed. Imatinib was the most frequently received treatment (72·4% of patients). Retrospective cytogenetic and molecular assessments at 3, 6, 12 or 18 months were available in 88·4% of patients. At the 12-month assessment, 32·2% were not in major molecular response (MMR). At last assessment, among 355 patients with duration of treatment ≥ 12 months, 91·5% had achieved MMR and 66·5% were in deep molecular response. This study, performed in everyday practice population of CML patients, suggests that monitoring of molecular responses in real-life practice is aligned with European LeukaemiaNet recommendations. The majority of patients still receiving first-line treatment are in optimal response, with a few being classified as in the warning area or responding to failure. PMID:27060881

    There are two different international standards for the treatment of follicular lymphoma (FL): intensified therapy followed by autologous stem-cell transplantation (ASCT) and conventional therapy in the first-line setting. However, their role remains unclear. Our aim was to define the treatment effect of intensified therapy followed by ASCT compared with conventional therapy as first-line treatment of patients with FL in terms of overall survival (OS) and event-free survival (EFS). We searched for randomised controlled trials in Medline, Embase, the Cochrane controlled trials register and the Science Citation Index (1985 to June 2011). Effect measures used were hazard ratios (HR) for OS, EFS and secondary tumour rate. Two independent review authors extracted data and assessed quality of trials. Four trials were identified, covering a total of 941 subjects. The random-effects summary HR by comparing the treatment effect on OS between intensified and conventional therapy was 0.95 [0.70, 1.30] (p = 0.75), indicating that no additional survival benefit was derived from the intensified therapy followed by ASCT. A significant benefit of intensified therapy followed by ASCT as first-line treatment was detected in terms of EFS: the random-effects summary HR (intensified versus conventional therapy) was 0.59 [0.44, 0.79] (p < 0.001). This meta-analysis showed that despite its superior EFS, intensified therapy followed by ASCT does not improve the OS compared with conventional therapy. PMID:22488650

    Background. Limited data are available describing the natural history of patients with HER2-positive and hormone receptor (HR)-positive metastatic breast cancer (MBC). We examined first-line treatment patterns and clinical outcomes in patients with HER2-positive, HR-positive MBC in a real-world setting. Methods. registHER is a prospective, observational cohort of 1,023 patients with HER2-positive MBC diagnosed within 6 months of enrollment and followed until death, disenrollment, or June 2009 (median follow-up time: 27 months). Demographics, first-line treatment patterns, and clinical outcomes were examined for 530 HER2-positive, HR-positive patients. Progression-free survival (PFS) and overall survival (OS) times were examined. Multivariate analyses adjusted for baseline demographic and prognostic factors. Results. HER2-positive, HR-positive patients receiving first-line trastuzumab plus hormonal therapy had significantly longer PFS times than patients who received hormonal therapy only (13.8 vs. 4.8 months; adjusted hazard ratio [HR]: 0.37, 95% confidence interval [CI]: 0.22–0.60); a nonsignificant reduction in OS time was observed (adjusted HR: 0.55, 95% CI: 0.27–1.14). Compared with patients who received first-line trastuzumab plus chemotherapy, patients who received first-line trastuzumab plus chemotherapy and hormonal therapy had longer median PFS times (20.4 months vs. 9.5 months; adjusted HR: 0.53, 95% CI: 0.42–0.68); a statistically significant reduction in risk of death was observed (adjusted HR: 0.50, 95% CI: 0.36–0.70). Sequential use of chemotherapy and hormonal therapy was associated with improved OS times when compared with concurrent use (adjusted PFS HR: 0.81, 95% CI: 0.54–1.21; adjusted OS HR: 0.48, 95% CI: 0.26–0.89). Conclusions. These real-world data in patients with HER2-positive/HR-positive MBC provide evidence that, with or without chemotherapy, dual targeting of HRs and HER2 receptors is associated with significantly prolonged

    Introduction Tenofovir-based first-line antiretroviral therapy (ART) is recommended globally. To evaluate the impact of its incorporation into the World Health Organization (WHO) guidelines, we examined treatment failure and drug resistance among a cohort of patients on tenofovir-based first-line ART at the Academic Model Providing Access to Healthcare, a large HIV treatment programme in western Kenya. Methods We determined viral load (VL), drug resistance and their correlates in patients on ≥six months of tenofovir-based first-line ART. Based on enrolled patients’ characteristics, we described these measures in those with (prior ART group) and without (tenofovir-only group) prior non-tenofovir-based first-line ART using Wilcoxon rank sum and Fisher's exact tests. Results Among 333 participants (55% female; median age 41 years; median CD4 336 cells/µL), detectable (>40 copies/mL) VL was found in 18%, and VL>1000 copies/mL (WHO threshold) in 10%. Virologic failure at both thresholds was significantly higher in 217 participants in the tenofovir-only group compared with 116 in the prior ART group using both cut-offs (24% vs. 7% with VL>40 copies/mL; 15% vs. 1% with VL>1000 copies/mL). Failure in the tenofovir-only group was associated with lower CD4 values and advanced WHO stage. In 35 available genotypes from 51 participants in the tenofovir-only group with VL>40 copies/mL (69% subtype A), any resistance was found in 89% and dual-class resistance in 83%. Tenofovir signature mutation K65R occurred in 71% (17/24) of the patients infected with subtype A. Patients with K65R had significantly lower CD4 values, higher WHO stage and more resistance mutations. Conclusions In this Kenyan cohort, tenofovir-based first-line ART resulted in good (90%) virologic suppression including high suppression (99%) after switch from non-tenofovir-based ART. Lower virologic suppression (85%) and high observed resistance levels (89%) in the tenofovir-only group impact future treatment

    Background Widespread parasite resistance to first-line treatment for uncomplicated malaria leads to introduction of new drug interventions. Introducing such interventions is complex and sensitive because of stakeholder interests and public resistance. To enhance take up of such interventions, health policy communication strategies need to deliver accurate and accessible information to empower communities with necessary information and address problems of cultural acceptance of new interventions. Objectives To explore community understanding of policy changes in first-line treatment for uncomplicated malaria in Kenya; to evaluate the potential role of policy communication in influencing responses to changes in first-line treatment policy. Methods Data collection involved qualitative strategies in a remote district in the Kenyan Coast: in-depth interviews (n = 29), focus group discussions (n = 14), informal conversations (n = 11) and patient narratives (n = 8). Constant comparative method was used in the analysis. Being malaria-prone and remotely located, the district offered an ideal area to investigate whether or not and how policy communication about a matter as critical as change of treatment policy reaches vulnerable populations. Results Three years after initial implementation (2009), there was limited knowledge or understanding regarding change of first-line treatment from sulphadoxine-pyrimethamine (SP) to artemether-lumefantrine (AL) for treatment of uncomplicated malaria in the study district. The print and electronic media used to create awareness about the drug change appeared to have had little impact. Although respondents were aware of the existence of AL, the drug was known neither by name nor as the official first-line treatment. Depending on individuals or groups, AL was largely viewed negatively. The weaknesses in communication strategy surrounding the change to AL included poor choice of communication tools, confusing

    Background Approximately one-third of HIV-infected children experience virological failure within two years of initiating antiretroviral therapy (ART). We determined the probability of switch to second-line ART or viral load (VL) re-suppression without switch among children who experienced VL rebound on first-line ART in an observational cohort in the UK/Ireland. Methods Children with VL rebound (confirmed VL>400c/ml following suppression <400c/ml) on first-line ART were included. Competing risk analysis estimated the probability of: switch to second-line; confirmed re-suppression (two consecutive VL<400c/ml) without switch; and continued VL>400c/ml without switch. Predictors of time to switch were assessed. Findings Of 900 children starting first-line ART who had VL<400c/ml by one year, 170 (19%) experienced VL rebound by median [IQR] 20·6 months [9·7-40·5]. At rebound, median age was 10·6 years [5·6-13·4], VL 3·6 log10c/ml [3·1-4·2], and CD4% 24 [17-32]. Eighty-nine (52%) switched to second-line ART at median 4·9 months [1·7-13·4] after VL rebound, 53 (31%) re-suppressed without switch (61% of those on PI-based and 24% of those on NNRTI-based first-line regimens), while 28 (16%) neither re-suppressed nor switched. At 12 months after rebound, probabilities of switch or re-suppression without switch were 38% (95% CI 30-45) and 27% (95% CI 21-34), respectively. Faster time to switch was associated with higher VL (p<0·0001), later calendar year (p=0·02) at VL rebound, and NNRTI- or triple NRTI- versus PI-based first-line (p=0·001). Interpretation One-third of children with VL rebound re-suppressed without switch. The possibility of re-suppression with adherence support should be considered prior to switching.

    The paper is to systematically evaluate the effect and safety of Shenqi Fuzheng injection (SFI) combined with first-line chemotherapy for non-small cell lung cancer (NSCLC). Randomized controlled trials (RCTs) on Shenqi Fuzheng injection (SFI) combined with first-line chemotherapy (experiment group) and chemotherapy alone group ( control group) were electronically retrieved from Medline, EMbase, Clinical Trials, Cochrane Library, CBM, CNKI, VIP, and Wanfang Data base. All trials were assessed for quality according to the Cochrane Reviewer's Handbook for Systematic Reviews of Intervention and then Meta-analysis was performed withRevMan5. 2 Software. A total of 43 RCTs (3433 patients) were included after screening and selecting. Results of Meta-analysis showed that: Objective remission rate (ORR): ORR of experimental group was about 20% higher than that of control group [RR = 1.23, 95% CI (1.11,1.35), P < 0.0001]. Disease control rate (DCR):DCR of SFI combined with first-line chemotherapy was 11% higher than that of first-line chemotherapy alone [RR = 1.11, 95% CI (1.07, 1.16), P < 0.000 01]. Life quality evaluated by Kosovan performance status (KPS) showed that: life quality improvement rate of experimental group was about twice of that in control group [RR = 2.02, 95% CI (1.81, 2.26), P < 0.000 01]. Toxic and side reaction analysis showed that: the incidence of side reactions in experimental group was about 50% lower than that in control group [RR = 0.59, 95% CI (0.53, 0.66), P < 0.000 01]. Immune function test showed that: the function of experimental group was 3.2 (standard deviations) times greater than that of control group [MD = 3.23, 95% CI (2.86, 3.60), P < 0.000 01]. We can see that SFI combined with first-line chemotherapy for NSCLC can increase objective efficacy, improve life quality, decrease toxic and side reactionsinduced by chemotherapy, and improve the immune functions. As most of the included studies in this systematic evaluation had poor quality

    Introduction. Despite the availability of several therapeutic options for metastatic breast cancer (MBC), no robust predictive factors are available to help clinical decision making. Nevertheless, a decreasing benefit from first line to subsequent lines of treatment is commonly observed. The aim of this study was to assess the impact of benefit from first-line therapy on outcome with subsequent lines. Methods. We analyzed a consecutive series of 472 MBC patients treated with chemotherapy (CT) and/or endocrine therapy (ET) between 2004 and 2012. We evaluated progression-free survival (PFS) at first (PFS1), second, third, and fourth therapeutic lines, according to treatment (ET and/or CT) and tumor subtypes. Results. In the whole cohort, median overall survival was 34 months, and median PFS1 was 9 months. A 6-month benefit was shown by 289 patients (63.5%) at first line, 128 (40.5%) at second line, 76 (33.8%) at third line, and 34 (23.3%) at fourth line. Not having a 6-month benefit at PFS1 was associated with less chance of benefit at second line (odds ratio [OR]: 0.48; 95% confidence interval [CI]: 0.29–0.77, p = .0026) and at any line beyond first (OR: 0.39; 95% CI: 0.24–0.62, p < .0001). In the total series, after stratification for tumor subtypes, a strong predictive effect was observed among HER2-positive tumors (OR: 0.2; 95% CI: 0.05–0.73, p = .0152). Conclusion. Our results suggest that the absence of at least a 6-month benefit in terms of PFS with first-line therapy predicts a reduced probability of benefit from subsequent therapeutic lines, especially in HER2-positive disease. Implications for Practice: This study supports evidence showing that the absence of a 6-month benefit in terms of progression-free survival with first-line therapy predicts a lack of benefit from subsequent therapeutic lines in metastatic breast cancer. The random distribution of benefit experienced by a subset of the cohort further spurs an interest in identifying predictive

    Purpose: To characterize the magnitude and kinetics of prostate-specific antigen (PSA) bounces after high-dose-rate (HDR) monotherapy and determine relationships between certain clinical factors and PSA bounce. Methods and Materials: Longitudinal PSA data and various clinical parameters were examined in 157 consecutive patients treated with HDR monotherapy between 1996 and 2005. We used the following definition for PSA bounce: rise in PSA ≥threshold, after which it returns to the prior level or lower. Prostate-specific antigen failure was defined per the Phoenix definition (nadir +2 ng/mL). Results: A PSA bounce was noted in 67 patients (43%). The number of bounces per patient was 1 in 45 cases (67%), 2 in 19 (28%), 3 in 2 (3%), 4 in 0, and 5 in 1 (1%). The median time to maximum PSA bounce was 1.3 years, its median magnitude was 0.7, and its median duration was 0.75 years. Three patients (2%) were noted to have PSA failure. None of the 3 patients who experienced biochemical failure exhibited PSA bounce. In the fully adjusted model for predicting each bounce, patients aged <55 years had a statistically significant higher likelihood of experiencing a bounce (odds ratio 2.22, 95% confidence interval 1.38-3.57, P=.001). There was also a statistically significant higher probability of experiencing a bounce for every unit decrease in Gleason score (odds ratio 1.52, 95% confidence interval 1.01-2.04, P=.045). Conclusions: A PSA bounce occurs in a significant percentage of patients treated with HDR monotherapy, with magnitudes varying from <1 in 28% of cases to ≥1 in 15%. The median duration of bounce is <1 year. More bounces were identified in patients with lower Gleason score and age <55 years. Further investigation using a model to correlate magnitude and frequency of bounces with clinical variables are under way.

    Introduction Tofacitinib is an oral Janus kinase inhibitor for the treatment of rheumatoid arthritis (RA). Tofacitinib monotherapy was previously shown to inhibit structural damage, reduce clinical signs and symptoms of RA, and improve physical functioning over 24 months in methotrexate (MTX)-naive adult patients with RA. In this post hoc analysis, we compared efficacy and safety of tofacitinib in patients with early (disease duration <1 year) versus established (≥1 year) RA. Methods MTX-naive patients ≥18 years with active RA received tofacitinib monotherapy (5 or 10 mg two times a day, or MTX monotherapy, in a 24-month Phase 3 trial. Results Of 956 patients (tofacitinib 5 mg two times a day, n=373; tofacitinib 10 mg two times a day, n=397; MTX, n=186), 54% had early RA. Baseline disease activity and functional disability were similar in both groups; radiographic damage was greater in patients with established RA. At month 24, clinical response rates were significantly greater in patients with early versus established RA in the tofacitinib 5 mg two times a day group. Both tofacitinib doses had greater effects on clinical, functional and radiographic improvements at 1 and 2 years compared with MTX, independent of disease duration. No new safety signals were observed. Conclusions Treatment response was generally similar in early and established RA; significantly greater improvements were observed at month 24 with tofacitinib 5 mg two times a day in early versus established RA. Tofacitinib 5 and 10 mg two times a day demonstrated greater efficacy versus MTX irrespective of disease duration. No difference in safety profiles was observed between patients with early or established RA. Trial registration number NCT01039688; Results. PMID:27493790

    Polymyxins are reserved for salvage therapy of infections caused by carbapenem-resistant Klebsiella pneumoniae (CRKP). Though synergy has been demonstrated for the combination of polymyxins with carbapenems or tigecycline, in vitro synergy tests are nonstandardized, and the clinical effect of synergy remains unclear. This study describes outcomes for patients with CRKP infections who were treated with polymyxin B monotherapy. We retrospectively reviewed the medical records of patients with CRKP infections who received polymyxin B monotherapy from 2007 to 2011. Clinical, microbiology, and antimicrobial treatment data were collected. Risk factors for treatment failure were identified by logistic regression. Forty patients were included in the analysis. Twenty-nine of 40 (73%) patients achieved clinical cure as defined by clinician-documented improvement in signs and symptoms of infections, and 17/32 (53%) patients with follow-up culture data achieved microbiological cure. End-of-treatment mortality was 10%, and 30-day mortality was 28%. In a multivariate analysis, baseline renal insufficiency was associated with a 6.0-fold increase in clinical failure after adjusting for septic shock (odds ratio [OR] = 6.0; 95% confidence interval [CI] = 1.22 to 29.59). Breakthrough infections with organisms intrinsically resistant to polymyxins occurred in 3 patients during the treatment. Eighteen of 40 (45%) patients developed a new CRKP infection a median of 23 days after initial polymyxin B treatment, and 3 of these 18 infections were polymyxin resistant. The clinical cure rate achieved in this retrospective study was 73% of patients with CRKP infections treated with polymyxin B monotherapy. Baseline renal insufficiency was a risk factor for treatment failure after adjusting for septic shock. Breakthrough infections with organisms intrinsically resistant to polymyxin B and development of resistance to polymyxin B in subsequent CRKP isolates are of concern. PMID:23959321

    Objective PI susceptibility results from a complex interplay between protease and Gag proteins, with Gag showing wide variation across HIV-1 subtypes. We explored the impact of pre-treatment susceptibility on the outcome of lopinavir/ritonavir monotherapy. Methods Treatment-naive individuals who experienced lopinavir/ritonavir monotherapy failure from the MONARK study were matched (by subtype, viral load and baseline CD4 count) with those who achieved virological response (‘successes’). Successes were defined by viral load <400 copies/mL after week 24 and <50 copies/mL from week 48 to week 96. Full-length Gag–protease was amplified from patient samples for in vitro phenotypic susceptibility testing, with susceptibility expressed as fold change (FC) relative to a subtype B reference strain. Results Baseline lopinavir susceptibility was lower in viral failures compared with viral successes, but the differences were not statistically significant (median lopinavir susceptibility: 4.4 versus 8.5, respectively, P = 0.17). Among CRF02_AG/G patients, there was a significant difference in lopinavir susceptibility between the two groups (7.1 versus 10.4, P = 0.047), while in subtype B the difference was not significant (2.7 versus 3.4, P = 0.13). Subtype CRF02_AG/G viruses had a median lopinavir FC of 8.7 compared with 3.1 for subtype B (P = 0.001). Conclusions We report an association between reduced PI susceptibility (using full-length Gag–protease sequences) at baseline and subsequent virological failure on lopinavir/ritonavir monotherapy in antiretroviral-naive patients harbouring subtype CRF02_AG/G viruses. We speculate that this may be important in the context of suboptimal adherence in determining viral failure. PMID:25228587

    AIM To draw a Meta-analysis over the comparison of the intraocular pressure (IOP)-lowering efficacy and safety between the commonly used fixed-combinations of prostaglandin analogs and 0.5% timolol with prostaglandin analogs (PGAs) monotherapy. METHODS After searching the published reports from MEDLINE, EMBASE, the Cochrane Library, all randomized controlled clinical trials (RCTs) comparing the fixed combination of PGAs/timolol therapy (FCs) and PGAs monotherapy with treatment duration at least 6mo were included. The efficacy outcomes were mean diurnal IOP, percentage of participants whose IOP were lower than 18 mm Hg, incidence of visual field change, while the safety outcomes included corneal side effects, hyperemia and eye irritation. The analysis was carried out in RevMan version 5.3 software. RESULTS After six-month medical intervention, the mean diurnal IOP of FCs was lower than PGAs (MD -1.14, 95% CI -1.82 to -0.46, P=0.001); the percentage of target IOP achieving between FCs and PGAs showed no significant difference (RR 1.18, 95% CI 0.97 to 1.43, P=0.10). No statistically significant differences of the incidence of hyperemia (RR 0.67, 95% CI 0.45 to 1.01, P=0.06) and eye irritation (RR 1.20, 95% CI 0.95 to 1.51, P=0.12) between the FCs and PGAs monotherapy were detected. Only one research involved in corneal events, result of this trial revealed no difference between two intervention groups regarding corneal effects (central endothelial cell density, MD -0.20, 95% CI -0.72 to 0.32, P=0.45; central corneal thickness, MD -0.01, 95% CI -0.02 to 0.00, P=0.23). The evaluation of visual field change was not performed due to the limited duration of the trials included in this Meta-analysis. CONCLUSION The long-term efficacy of the FCs overweighed the PGAs monotherapy in lowering IOP, but in the incidence of hyperemia and eye irritation syndromes, the differences are not statically significant. More RCTs with detailed and authentic data over the assessments of

    The potential of phenobarbital to interact with DNA has been studied using the sister chromatid exchange (SCE) assay in peripheral lymphocytes of nine adult male patients with epilepsy and of their matched controls. All patients were otherwise healthy individuals, treated chronically with phenobarbital in monotherapy. No statistically significant differences in SCE levels were found between the patient and control groups. Smoking was associated with increased SCE frequencies. The experiment was repeated with five available patients, using a slightly modified methodology. Although different SCE scores were obtained, the results of both tests were comparable. PMID:2585535

    A 72-year-old man was diagnosed with rheumatoid arthritis (RA) and prior hepatitis B virus (HBV) infection. He began treatment with salazosulfapyridine (SASP). Several months later, his blood tests reflected a slightly elevated liver function. Serum tests were positive for hepatitis B surface antigen and HBV-DNA, and the diagnosis of de novo HBV hepatitis was made. A genetic analysis showed that he had polymorphisms of ABCG2 and NAT2, which could lead to high plasma concentrations of SASP and sulfapyridine. To the best of our knowledge, this is the first report of de novo hepatitis developing during SASP monotherapy for RA. PMID:27181550

    Perennial allergic rhinitis (PAR) is very common in children and has a relevant impact on their families. House dust mites (HDM) are the most relevant cause of PAR. The present pilot study aimed to evaluate whether hypertonic saline (3%) nasal spray as monotherapy is able to improve: nasal symptom severity and parental perception of rhinitis control, sleep, and school performance in HDM-mono-sensitized children with PAR. Globally, 25 children (13 males and 12 females; mean age 9.5±3.1 years) were treated for 3 weeks. They were visited at baseline, at the end of treatment, and after a 2-week follow-up. Hypertonic saline significantly reduced total symptom score, and improved the perception, according to their parents, of rhinitis control, sleep, and school performance. In conclusion, the present pilot study provided the first evidence that 3% hypertonic saline monotherapy was able to relieve nasal symptoms and parental perception of PAR impact as well as being safe and well tolerated.

    Introduction. Levetiracetam (LEV) is a newer antiepileptic drug with better pharmacokinetic profile. Currently, it is frequently used for the treatment of partial seizures. The present study was undertaken to compare the efficacy and safety of LEV and Carbamazepine (CBZ) in partial epilepsy. Methods. This was a prospective, open labeled, randomized study. It was conducted in participants suffering from partial seizures after the approval of ethics committee and written informed consent. The first group received Tab LEV (500 to 3000 mg/day) and the second group received Tab CBZ (300 to 600 mg/day). The primary outcomes were efficacy and safety. The secondary outcome was the Quality of Life (QOL). Efficacy was assessed by comparing the seizure freedom rates at the end of 6 months. Safety profile was evaluated by comparing the adverse effects. QOL was assessed by QOLIE-10 scale. Results. The overall seizure freedom rate at the end of 6 months was 71.42% in CBZ group compared to 78.57% in LEV group (p = 0.2529). Both LEV and CBZ reported a similar incidence of adverse reactions. LEV group reported more behavioral changes like increased aggression and anxiety. Also, it showed better QOL compared to the CBZ group. Conclusion. LEV monotherapy and CBZ monotherapy demonstrated similar efficacy for treatment of partial epilepsy and were found to be well tolerated. PMID:26798511

    Background The objective of this study was to review our experience with radical prostatectomy (RP) as monotherapy for men with high-risk prostate cancer (PCa). Patients and Methods This study included 382 consecutive patients who were diagnosed with high-risk PCa according to the D'Amico definition and subsequently underwent RP without neoadjuvant therapy. Biochemical recurrence (BR) was defined as a serum prostate-specific antigen (PSA) level ≥ 0.2 ng/ml on two consecutive measurements, and none of the patients received any adjuvant therapies until their serum PSA levels reached ≥ 0.4 ng/ml. Results The median preoperative serum PSA level in these 382 patients was 15.9 ng/ml. Pathological stages ≥ pT2c and Gleason scores ≥ 8 were observed in 288 and 194 patients, respectively. During the observation period (median, 48.0 months), BR occurred in 134 patients, and the 5-year BR-free survival rate was 60.1%; however, no patient died of cancer progression. Multivariate analysis identified capsular invasion, seminal vesicle invasion, and surgical margin status as independent predictors of BR. Conclusions Comparatively favorable cancer control could be achieved using RP as monotherapy for men with high-risk PCa; however, RP alone may be insufficient for patients with capsular invasion, seminal vesicle invasion, and/or surgical margin positivity.

    The study aims to compare serial changes in prostate-specific antigen (PSA), testosterone, dehydroepiandrosterone (DHEA), and androstenedione in patients treated with either of the antiandrogen agents, bicalutamide or flutamide, using a randomized controlled study. Patients had to meet the following inclusion criteria: (1) presence of histopathologically confirmed prostate cancer, (2) prostate cancer treatment naive, (3) no current treatment with luteinizing hormone-releasing hormone (LH-RH) agonist for sexual interest and physical capacity, (4) clinical stage T1-cT3N0M0, (5) Gleason score ≤ 7, and (6) Cooperative Oncology Group performance status 0-1. Patients were randomly allocated to two groups: flutamide and bicalutamide monotherapy group 1:1. PSA levels were significantly decreased in both groups at 4 weeks. PSA levels were significantly lower in the bicalutamide group compared with the flutamide group at 4 and 8 weeks. Testosterone levels in the bicalutamide group were significantly higher than the baseline levels between 4 and 24 weeks of treatment. Testosterone levels in the flutamide group were significantly increased at 4 and 12 weeks and returned to baseline levels at 16 and 24 weeks. DHEA levels in the bicalutamide group were unchanged from baseline at 4 and 24 weeks. However, DHEA levels in the flutamide group were decreased at 24 weeks. Androstenedione levels increased slightly in both groups, but the increase did not reach statistical significance. PSA, testosterone, and DHEA levels significantly differed between bicalutamide and flutamide monotherapy. PMID:26024831

    To identify potential risk factors for the development of subclinical hypothyroidism following long-term valproic acid monotherapy in children with epilepsy. Serum levels of thyroid-stimulating hormone, free thyroxine, free triiodothyronine, thyreoglobulin antibodies, and thyroid peroxidase antibodies were determined in 41 patients and in 41 sex- and age-matched healthy children. Mean valproic acid treatment duration was 2.80±1.96 years. The valproic acid group had higher serum thyroid-stimulating hormone (p<0.001) and free triiodothyronine (p<0.05) levels compared to the control group. Serum thyroid-stimulating hormone and free triiodothyronine were above the upper limit for healthy controls in 34% and 32% of patients, respectively, and no clinical features of thyroid dysfunction were observed. Duration of valproic acid monotherapy for less than four years was a risk factor for elevated thyroid-stimulating hormone levels. One third of children with normal range serum valproic acid levels may have elevated serum thyroid-stimulating hormone and free triiodothyronine levels, especially in the first four years of treatment.

    Purpose Enzyme replacement therapy (ERT) with recombinant human GAA (rhGAA) prolongs survival in infantile Pompe disease (IPD). However, the majority of cross reactive immunologic material (CRIM)-negative (CN) patients have immune responses with significant clinical decline despite continued ERT. We aimed to characterize immune responses in CN IPD patients receiving ERT monotherapy. Methods A chart review identified 20 CN IPD patients treated with ERT monotherapy for ≥6 months. Patients were stratified by anti-rhGAA antibody titers: high sustained antibody titers (HSAT) ≥51,200 at least twice; low titers (LT) <6,400 throughout treatment; or sustained intermediate titers (SIT) 6,400–25,600. Results Despite early initiation of treatment, the majority (85%) of CN patients developed significant antibody titers, most with HSAT associated with invasive ventilation and death. Nearly all patients with HSAT had at least one nonsense GAA mutation, while the LT group exclusively carried splice site or frameshift mutations. Only one patient in the HSAT group is currently alive after successful immune modulation in the entrenched setting. Conclusion Immunological responses are a significant risk in CN IPD; thus, immune tolerance induction in the naïve setting should strongly be considered. Further exploration of factors influencing immune responses is required, particularly with the advent of newborn screening for Pompe disease. PMID:25741864

After chemotherapy, radiotherapy was added to the chest wall, supraclavicular and parasternal regions. In March 2002 (disease-free interval of one year), liver metastasis was revealed. Systemic therapy using docetaxel, and hepatic artery infusion therapy with epirubicin following docetaxel, failed. Since June 2003, capecitabine monotherapy (2,400 mg/day) was initiated for the liver and lymph node metastases in the mediastinum and retroperitoneum. After 3 cycles, all metastases responded and a marked response has been maintained for 15 months. This therapy is being continued (18 cycles), and no serious side effects have been encountered. Capecitabine monotherapy is safe and very useful for recurrent breast cancer. PMID:16121919

    Attenuated Salmonella typhimurium injected in the circulatory system of mammals selectively targets tumors. Using weekly intraperitoneal injections of attenuated Salmonella strain CRC2631, we tested for regression and/or inhibition of tumor development in the TRAMP prostate tumor mouse model, which utilizes SV40 early region expression for autochthonous formation of prostate tumors that progress into metastatic, poorly differentiated prostatic carcinomas in an immunocompetent murine model. Thirteen weekly intraperitoneal administrations of 105–107 CFU CRC2631 into 10 week old mice were well tolerated by the TRAMP model. Sacrifice and histological analysis of TRAMP prostates at 22 weeks indicated that Salmonella monotherapy at administrated levels decrease visible tumor size (>29%) but did not significantly inhibit previously described SV40 expression-driven TRAMP tumor progression to undifferentiated carcinomas when histologically examined. In conclusion, this work demonstrates baseline results for CRC2631 Salmonella monotherapy using the immunocompetent TRAMP prostate tumor model in preparation for study of combination therapies that resolve autochthonously generated TRAMP prostate tumors, further reduce tumor size, or inhibit prostate tumor progression.

    Thus far, several small studies and case reports on the use of topical immunomodulators in vitiligo have been published. We undertook a comprehensive literature review, searching for studies evaluating clinical response to tacrolimus topical therapy for vitiligo. A search was performed on PubMed/Medline using the term “vitiligo”, combined with “topical” and “ointment”. Our inclusion criteria were: use of tacrolimus ointment as monotherapy to treat vitiligo. We found 29 studies from 2002 to 2014. Overall, 709 patients were treated in 29 studies. Pooling the lesions, 50% repigmentation of vitiligo patches was never achieved before 2 months of treatment, with a peak after 6 months of therapy. The best results were obtained on lesions of the cephalic region, especially the face, with tacrolimus 0.1% ointment two times daily. The percentage of non-responsive patients ranged from 0% to 14%. Treatment was generally well-tolerated; only localized adverse effects were reported. Our objective was to verify the effectiveness and safety of tacrolimus ointment monotherapy. It has good efficacy and tolerability. At present, only small trials and case series are available in the literature. Further, standardized investigations on a larger number of patients are needed.

    BACKGROUND The prevalence of allergic diseases has been dramatically rising in the United States and other developed nations over recent decades. Growing evidence suggests a partial role for the microbiome in the development of these allergic diseases. Food protein-induced allergic proctocolitis (AP) (also referred to as cow's milk protein intolerance or allergy) is among the earliest and most common food allergic diseases of infancy, yet its pathophysiology is not well understood. The currently accepted clinical practice is to restrict the diet until 12 months of age. CASE REPORT We present 4 cases of clinically diagnosed AP whose symptoms quickly and completely resolved with probiotic Lactobacillus rhamnosus GG (LGG) monotherapy. All 4 infants avoided any dietary restrictions. The range of time from probiotic initiation to symptom resolution was 7-28 days. CONCLUSIONS These cases suggest an important role for the infant intestinal microbiome in the development of gastrointestinal mucosal food allergies such as AP. Prospective investigation of the intestinal microbiome in infants with AP may further our understanding of this disease's pathogenesis. The potential use of probiotic monotherapy in the treatment of AP also warrants further investigation. PMID:27568925

    Abstract Mitotane has been used for more than 5 decades as therapy for adrenocortical carcinoma (ACC). However its mechanism of action and the extent of tumor response remain incompletely understood. To date no cases of rapid and complete remission of metastatic ACC with mitotane monotherapy has been reported. A 52-year-old French Canadian man presented with metastatic disease 2 years following a right adrenalectomy for stage III nonsecreting ACC. He was started on mitotane which was well tolerated despite rapid escalation of the dose. The patient course was exceptional as he responded to mitotane monotherapy after only few months of treatment. Initiation of chemotherapy was not needed and he remained disease-free with good quality of life on low maintenance dose of mitotane during the following 10 years. A germline heterozygous TP53 exon 4 polymorphism c.215C>G (p. Pro72Arg) was found. Immunohistochemical stainings for IGF-2 and cytoplasmic β-catenin were positive. Advanced ACC is an aggressive disease with poor prognosis and the current therapeutic options remain limited. These findings suggest that mitotane is a good option for the treatment of metastatic ACC and might result in rapid complete remission in selected patients. PMID:27043680

    Nilotinib is a second-generation tyrosine kinase inhibitor that has been approved for the first-line treatment of chronic-phase chronic myeloid leukemia, based on the results of a prospective randomized study of nilotinib versus imatinib (ENESTnd). Apart from this registration study, very few data are currently available on first-line nilotinib treatment. We report here the long-term, 6-year results of the first investigator-sponsored, GIMEMA multicenter phase 2, single-arm trial with nilotinib 400 mg twice daily as first-line treatment in 73 patients with chronic-phase chronic myeloid leukemia. Six-year overall survival and progression-free survival rates were 96%, with one death after progression to blast phase. At 6 years, 75% of the patients were still on nilotinib. The cumulative incidence of major molecular response was 98%; only one patient had a confirmed loss of major molecular response. The cumulative incidence of deep molecular response (MR 4.0) was 76%. Deep molecular response was stable (≥2 years) in 34% of these patients. Cardiovascular adverse events, mainly due to arterial thrombosis, occurred in 11/73 patients (15%), after 24 to 76 months of therapy. They were more frequent in elderly patients, and in those with baseline cardiovascular risk factors. None was fatal, although there was a relevant morbidity. This is the study with the longest follow-up of a high dose of nilotinib (400 mg twice daily): it highlights the high efficacy and the cardiovascular toxicity of the drug (CTG.NCT.00481052).

    The first-line standard of care for patients with metastatic colorectal cancer (mCRC) is FOLFIRI (irinotecan, levo-leucovorin, 5-fluorouracil (5-FU)) plus bevacizumab. With the renewed interest in cancer immunotherapy with agents such as vaccines, checkpoint inhibitors and immune modulators, the possibility exists for the use of one or more of these immunotherapeutics in the first-line setting and thus in combination with the FOLFIRI and bevacizumab regimen. Studies were undertaken to study the effects of FOLFIRI and bevacizumab therapy on peripheral T-cell subsets, and to determine if there are any associations between these subsets and response to therapy. Peripheral blood mononuclear cell subsets of patients with mCRC (n = 23) were analyzed prior to and during therapy. While there were differences among patients, the majority of patients showed either a minimal change or an increase in CD4(+) T cell to regulatory T cell (Treg) ratios during therapy, as well as either minimal change or a decrease in Treg suppressive activity during therapy. There was also an association (p = 0.036) between a decrease in Treg frequency during FOLFIRI therapy and overall survival, and an association (p = 0.037) between the frequency of Tregs prior to therapy and progression-free survival. Responders to the chemotherapy by RECIST criteria also had a greater decrease in Tregs during therapy vs. pre-therapy (p = 0.0064) as compared to non-responders. While the number of mCRC patients undergoing chemotherapy in this study is relatively small, it provides the rationale for the use of immunotherapeutics in this first-line metastatic setting.

    It is impossible to conduct head-to-head trials of all the therapies to determine optimal treatment in the rapidly advancing era of therapies for metastatic renal cell carcinoma (mRCC). In this network meta-analysis,we aimed to compare efficacy and safety of first-line treatments for mRCC. We searched PubMed, Embase, the Cochrane Central Register of Controlled Trials, and unpublished studies were also sought through “clinicaltrials.gov” from their inception through January 31, 2016. A database search identified 1253 articles, with 11 studies meeting the eligibility criteria. A total of 7597 patients in twelve different treatment arms were assessed. Network meta-analysis showed sunitinib had a significantly longer PFS than IFN-α (SMD=−5.68; 95%CI: −10.76,−0.86; P<0.001) and placebo (SMD=−6.71; 95%CI: −12.65,−0.79; P<0.001), meanwhile, pazopanib had a significantly longer PFS compared with placebo (SMD=5.13; 95%CI: 0.43, 10.09; P<0.001). The cumulative ranking probability curve indicated that sunitinib had the highest probability of being the best treatment modality in terms of PFS and it also had the highest probability of being the safest drugs as the first-line treatment when it came to SAE. Thus, sunitinib might be the best choice of first-line treatment for patients with mRCC because it has the most favorable balance between efficacy and safety. PMID:26908455

    Objectives Document progress in HIV-treatment in the Netherlands since 1996 by reviewing changing patterns of cART use and relating those to trends in patients' short-term clinical outcomes between 1996 and 2010. Design and Methods 1996–2010 data from 10,278 patients in the Dutch ATHENA national observational cohort were analysed. The annual number of patients starting a type of regimen was quantified. Trends in the following outcomes were described: i) recovery of 150 CD4 cells/mm3 within 12 months of starting cART; ii) achieving viral load (VL) suppression ≤1,000 copies/ml within 12 months of starting cART; iii) switching from first-line to second-line regimen within three years of starting treatment; and iv) all-cause mortality rate per 100 person-years within three years of starting treatment. Results Between 1996 and 2010, first-line regimens changed from lamivudine/zidovudine-based or lamivudine/stavudine-based regimens with unboosted-PIs to tenofovir with either emtricitabine or lamivudine with NNRTIs. Mortality rates did not change significantly over time. VL suppression and CD4 recovery improved over time, and the incidence of switching due to virological failure and toxicity more than halved between 1996 and 2010. These effects appear to be related to the use of new regimens rather than improvements in clinical care. Conclusion The use of first-line cART in the Netherlands closely follows changes in guidelines, to the benefit of patients. While there was no significant improvement in mortality, newer drugs with better tolerability and simpler dosing resulted in improved immunological and virological recovery and reduced incidences of switching due to toxicity and virological failure.

    Background There are no head-to-head randomised controlled trials (RCTs) comparing the effectiveness of biologics in ulcerative colitis (UC). We aimed to assess the cost-effectiveness of adalimumab, infliximab and vedolizumab as first-line agents to induce clinical remission and mucosal healing (MH) in UC. Methods We constructed a decision tree based on a payer's perspective in the USA to estimate the first year costs of adalimumab, infliximab or vedolizumab to achieve clinical remission and MH in patients with moderate-to-severe UC. Transition probabilities were derived from ACT, ULTRA and GEMINI RCT data. Costs were derived from Medicare reimbursement rates and wholesale drug prices. Results Assuming a biological-naïve cohort, infliximab 5 mg/kg every 8 weeks was more cost-effective ($99 171 per MH achieved) than adalimumab 40 mg every other week ($316 378 per MH achieved) and vedolizumab every 8 weeks ($301 969 per MH achieved) at 1 year. Non-drug administration cost of infliximab exceeding $1974 per infusion would make adalimumab more cost-effective. First-line UC therapy with vedolizumab would be cost-effective if the drug acquisition price was <$2537 for each 300 mg administration during the 1-year time horizon. Conclusions If non-drug costs of infliximab administration are not excessive (<$2000), infliximab is the most cost-effective first-line biologic for moderate-to-severe UC. Exceeding this threshold infusion-related cost would make adalimumab the more cost-effective therapy. Considering its drug costs in the USA, vedolizumab appears to be appropriately used as a second-line biologic after antitumour necrosis factor failure. PMID:27195130

    The RCC-SELECT study showed the correlation between single nucleotide polymorphisms (SNP) in STAT3 gene and survival in metastatic renal cell carcinoma (mRCC) patients with first-line interferon-α (IFN-α). In that study, even patients with STAT3 SNP linked to shorter overall survival (OS) exhibited remarkably improved prognosis. All 180 patients evaluated in the above study were further analyzed for correlation between OS and demographics/clinicopathological parameters. OS was estimated using the Kaplan-Meier method. Associations between OS and potential prognostic factors were assessed using the log-rank test and the Cox proportional hazards model. The median OS was 42.8 months. Univariate analysis showed that worse Eastern Cooperative Oncology Group-performance status (ECOG-PS), high T stage, regional lymph node metastasis, distant metastasis, higher grade, infiltrative growth pattern, the presence of microscopic vascular invasion (MVI), hypercalcemia, anemia, thrombocytopenia and elevated C-reactive protein were significantly associated with OS. Multivariate analysis revealed that ECOG-PS (hazard ratio [HR] = 3.665, P = 0.0004), hypercalcemia (HR = 6.428, P = 0.0005) and the presence of MVI (HR = 2.668, P = 0.0109) were jointly significant poor prognostic factors. This is the first study analysing prognostic factors of mRCC patients with first-line IFN-α using large cohort of the prospective study. The present study suggests that first-line IFN-α is still a useful therapy for mRCC even in the era of molecular targeted therapy. PMID:27089226

    Introduction Moderate to severe anemia is an important clinical problem in HIV patients on Highly Active Antiretroviral Therapy. The rate of progression and mortality in this sub group of patients is high compared to non anemic patients. In sub Saharan Africa with scale up of Anti retroviral therapy, the magnitude of this problem is not known especially in Tanzania. This study aimed at determining the magnitude and correlates of moderate to severe anemia in HIV patients receiving first line ART in northwestern Tanzania. Methods This was a cross sectional clinic based study, involving adult HIV patients on first line Highly Active Antiretroviral Therapy at Bugando Medical Centre Care and Treatment Center. The patients’ data were analyzed using STATA version 11 to determine the prevalence of moderate to severe anemia and risk factors that could predict occurrence of anemia. Results In this study 346 patients on Highly Active Anti-Retroviral Therapy were enrolled, of whom 100(40.46%) had moderate to severe anemia. The odds of being anemic were strongly predicted by Zidovudine based regime, low baseline CD4 count (< 200 cells/μl) and HIV stage 3&4 at enrollment. Most of the anemic patients had mean corpuscular volume of >100fl. Conclusion The prevalence of moderate to severe anemia is significantly high in this cohort of HIV-infected patients on first line Anti Retroviral Therapy and it is strongly predicted by Zidovudine based regime, low baseline CD4 and HIV stage 3 and 4. On clinical grounds this suggests that patients who are initiated on Zidovudine based regimen and those in advanced HIV at enrollment should have regular haemoglobin follow up to identify anemia at its earliest stage to improve the clinical outcome of these patients.

    Background A 4-month first-line treatment regimen for tuberculosis disease (TB) is expected to have a direct impact on patient outcomes and societal costs, as well as an indirect impact on Mycobacterium tuberculosis transmission. We aimed to estimate this combined impact in a high TB-burden country: South Africa. Method An individual based M. tb transmission model was fitted to the TB burden of South Africa using a standard TB natural history framework. We measured the impact on TB burden from 2015–2035 of introduction of a non-inferior 4-month regimen replacing the standard 6-month regimen as first-line therapy. Impact was measured with respect to three separate baselines (Guidelines, Policy and Current), reflecting differences in adherence to TB and HIV treatment guidelines. Further scenario analyses considered the variation in treatment-related parameters and resistance levels. Impact was measured in terms of differences in TB burden and Disability Adjusted Life Years (DALYs) averted. We also examined the highest cost at which the new regimen would be cost-effective for several willingness-to-pay thresholds. Results It was estimated that a 4-month regimen would avert less than 1% of the predicted 6 million person years with TB disease in South Africa between 2015 and 2035. A similarly small impact was seen on deaths and DALYs averted. Despite this small impact, with the health systems and patient cost savings from regimen shortening, the 4-month regimen could be cost-effective at $436 [NA, 5983] (mean [range]) per month at a willingness-to-pay threshold of one GDP per capita ($6,618). Conclusion The introduction of a non-inferior 4-month first-line TB regimen into South Africa would have little impact on the TB burden. However, under several scenarios, it is likely that the averted societal costs would make such a regimen cost-effective in South Africa. PMID:26717007

    2014-01-01

    Background There is a high unmet need for effective treatments for patients with squamous non-small cell lung cancer (NSCLC). Eli Lilly and Company is conducting a phase III, randomized, multicenter, open-label study of gemcitabine plus cisplatin plus necitumumab (GC + N) versus gemcitabine plus cisplatin (GC) for the first-line treatment of patients with stage IV squamous NSCLC. Given GC is not the only treatment commonly used for the treatment of squamous NSCLC, this study was designed to compare the survival, toxicity, and quality of life outcomes of current treatment strategies for squamous NSCLC in the first-line setting. Methods/Design A systematic review and meta-analysis (including indirect comparisons) of treatments used in squamous NSCLC will be conducted to assess the clinical efficacy (overall and progression-free survival), health-related quality of life (HRQoL), and safety (grade 3–4 toxicity) of GC + N compared to other treatments used in squamous NSCLC. PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines will be followed for all aspects of this study. A systematic literature review will be conducted to identify randomized controlled trials evaluating chemotherapy treatment in first-line NSCLC. Eligible articles will be restricted to randomized controlled trials (RCTs) among chemotherapy-naïve advanced NSCLC cancer patients that report outcome data (survival, toxicity, or quality of life) for patients with squamous histology. Following data extraction and validation, data consistency and study heterogeneity will be assessed. A network meta-analysis will be conducted based on the available hazard ratios for overall and progression-free survival, odds ratios for published toxicity data, and mean difference of HRQoL scales. Sensitivity analyses will be conducted. Discussion This is a presentation of the study protocol only. Results and conclusions are pending completion of this study. Systematic review

    Purpose To assess the efficacy of pemetrexed plus platinum doublet chemotherapy as first-line treatment for advanced nonsquamous non-small-cell lung cancer (NSCLC) through a trial-level meta-analysis. Methods Trials published between 1990 and 2015 were identified by an electronic search of public databases (Medline, Embase, and Cochrane Library). All clinical studies were independently identified by two authors. Demographic data, treatment regimens, objective response rate (ORR), progression-free survival (PFS), and overall survival (OS) were extracted and analyzed using comprehensive meta-analysis software (version 2.0). Results A total of 2,551 patients with advanced nonsquamous NSCLC from ten trials were included for analysis: 1,565 patients were treated with pemetrexed plus platinum doublet chemotherapy and 986 with platinum plus other first-line chemotherapy. Pooled ORR for pemetrexed plus platinum chemotherapy was 37.8% (95% confidence interval [CI]: 31.7%–44.3%), with median PFS and OS of 5.7 and 16.05 months, respectively. When compared to other platinum-based doublet chemotherapies, the use of pemetrexed plus platinum chemotherapy significantly improved OS (hazard ratio [HR] =0.86, 95% CI: 0.77–0.97, P=0.01) but not PFS (HR =0.90, 95% CI: 0.80–1.01, P=0.084) in advanced nonsquamous NSCLC patients. Conclusion Pemetrexed plus platinum doublet regimen is an efficacious treatment for advanced nonsquamous NSCLC patients. Our findings support the use of pemetrexed plus platinum doublet regimen as first-line treatment in advanced nonsquamous NSCLC patients because of its potential survival benefits. PMID:27042115
