Background: Dupilumab, a fully human monoclonal antibody that blocks the shared receptor component for interleukin-4 and interleukin-13, reduced exacerbations and improved lung function in patients with chronic obstructive pulmonary disease (COPD) and type 2 inflammation in the phase 3 BOREAS trial.
Objective: To assess clinical outcomes in patients from BOREAS by emphysema status.
Methods: Patients with COPD and type 2 inflammation (screening blood eosinophils ≥300 cells/μL) on maximal inhaled therapy were randomized to add-on dupilumab 300 mg or placebo every 2 weeks for 52 weeks.
Introduction: In chronic spontaneous urticaria (CSU), interleukin (IL)-4 and IL-13 may promote mast cell activation directly via IL-4 receptor expression, or indirectly via upregulated immunoglobulin E (IgE) production. Dupilumab significantly improved CSU signs and symptoms in the phase 3, randomized, placebo-controlled LIBERTY-CSU CUPID Study A. This analysis explores the impact of dupilumab on CSU signs and symptoms and serum IgE levels in patients from LIBERTY-CSU CUPID Study A with serum total IgE above and below 100 IU/mL at baseline.
View Article and Find Full Text PDFBackground: Dupilumab, a fully human monoclonal antibody that blocks the shared receptor component for interleukin-4 and interleukin-13, key and central drivers of type 2 inflammation, has shown efficacy and safety in a phase 3 trial involving patients with chronic obstructive pulmonary disease (COPD) and type 2 inflammation and an elevated risk of exacerbation. Whether the findings would be confirmed in a second phase 3 trial was unclear.
Methods: In a phase 3, double-blind, randomized trial, we assigned patients with COPD who had a blood eosinophil count of 300 cells per microliter or higher to receive subcutaneous dupilumab (300 mg) or placebo every 2 weeks.
Background: Chronic spontaneous urticaria (CSU) is a chronic inflammatory disease characterized by recurrent pruritic wheals (hives) and/or angioedema. Patients with CSU could remain symptomatic despite standard-of-care H antihistamines (H1-AH) or anti-IgE (omalizumab) treatment. Dupilumab blocks IL-4/IL-13 signaling and is approved for multiple type 2/atopic indications.

View Article and Find Full Text PDFBackground: In some patients with chronic obstructive pulmonary disease (COPD), type 2 inflammation may increase exacerbation risk and may be indicated by elevated blood eosinophil counts. Dupilumab, a fully human monoclonal antibody, blocks the shared receptor component for interleukin-4 and interleukin-13, key drivers of type 2 inflammation.
Methods: In a phase 3, double-blind, randomized trial, we assigned patients with COPD who had a blood eosinophil count of at least 300 per microliter and an elevated exacerbation risk despite the use of standard triple therapy to receive dupilumab (300 mg) or placebo subcutaneously once every 2 weeks.
Introduction: Bidirectional effects between cognition and pain have been extensively reported. Although brain regions involved in cognitive and pain processing seem to partly overlap, it is unknown what specific brain regions are involved in the interaction between pain and cognition. Furthermore, the role of gonadal hormones on these interacting effects has not been examined.

Long-term potentiation (LTP) is thought to be a critical mechanism underlying learning and memory. Although LTP is now widely performed in neuroscience research laboratories and the theory behind it is taught in many undergraduate courses, it is rare for undergraduate students to have the opportunity to perform LTP experiments themselves. Here, we describe a series of two laboratory sessions in which upper level students learn how to perform LTP experiments in acute hippocampal slices from wild type mice.

Objective: To evaluate the efficacy and safety of sarilumab plus conventional synthetic disease-modifying antirheumatic drugs (DMARDs) in patients with active moderate-to-severe rheumatoid arthritis (RA) who had an inadequate response or intolerance to anti-tumor necrosis factor (anti-TNF) therapy.
Methods: Patients were randomly allocated to receive sarilumab 150 mg, sarilumab 200 mg, or placebo every 2 weeks for 24 weeks with background conventional synthetic DMARDs. The co-primary end points were the proportion of patients achieving a response according to the American College of Rheumatology 20% criteria for improvement (ACR20) at week 24, and change from baseline in the Health Assessment Questionnaire disability index (HAQ DI) at week 12.
Objectives: To compare efficacy and safety of sarilumab monotherapy with adalimumab monotherapy in patients with active rheumatoid arthritis (RA) who should not continue treatment with methotrexate (MTX) due to intolerance or inadequate response.
Methods: MONARCH was a randomised, active-controlled, double-blind, double-dummy, phase III superiority trial. Patients received sarilumab (200 mg every 2 weeks (q2w)) or adalimumab (40 mg q2w) monotherapy for 24 weeks.

We aimed to assess the efficacy and safety of teriflunomide in patients with a first clinical episode suggestive of multiple sclerosis.
Methods: In this randomised, double-blind, placebo-controlled, parallel-group study, we enrolled patients aged 18-55 years with clinically isolated syndrome (defined as a neurological event consistent with demyelination, starting within 90 days of randomisation, and two or more T2-weighted MRI lesions ≥3 mm in diameter) from 112 centres (mostly hospitals) in 20 countries.
Objectives: The goal of this study was to investigate the differential efficacy of clopidogrel or aspirin monotherapy according to smoking status in patients with atherosclerotic vascular disease.
Background: Smoking enhances clopidogrel-induced platelet inhibition, which may explain the higher relative benefit among smokers observed in trials evaluating dual antiplatelet therapy. Whether smoking has an impact on clinical outcomes in patients requiring a single antiplatelet agent remains unknown.
Background: In previous studies, teriflunomide significantly reduced the annualised relapse rate (ARR) and disability progression.
Objective: This phase 3, rater-blinded study (NCT00883337) compared teriflunomide with interferon-beta-1a (IFNβ-1a).
Methods: Patients with relapsing multiple sclerosis were randomised (1:1:1) to oral teriflunomide 7-or 14 mg, or subcutaneous IFNβ-1a 44 µg.
Objective: To investigate the effect of teriflunomide on the efficacy and safety of seasonal influenza vaccine.
Methods: The 2011/2012 seasonal influenza vaccine (containing H1N1, H3N2, and B strains) was administered to patients with relapsing forms of multiple sclerosis (RMS) treated for ≥6 months with teriflunomide 7 mg (n = 41) or 14 mg (n = 41), or interferon-β-1 (IFN-β-1; n = 46). The primary endpoint was the proportion of patients with influenza strain-specific antibody titers ≥40, 28 days postvaccination.
Background: Proton pump inhibitors (PPIs) may interfere with the metabolic activation of clopidogrel via inhibition of cytochrome P450 2C19, but the clinical implications remain unclear.
Methods And Results: The impact of PPI use on the 1-year primary end point (ischemic stroke, myocardial infarction [MI], or vascular death) in the Clopidogrel versus Aspirin in Patients at Risk of Ischemic Events (CAPRIE) trial and the 28-day (all-cause death, MI, or urgent target vessel revascularization) and 1-year (all-cause death, MI, or stroke) primary end points in the Clopidogrel for Reduction of Events During Observation (CREDO) trial were examined. Clopidogrel appeared to elevate risk for the primary end point in CAPRIE among PPI users (estimated hazard ratio [EHR] 2.
GLAST is the predominant glutamate transporter in the cerebellum and contributes substantially to glutamate transport in forebrain. This astroglial glutamate transporter quickly binds and clears synaptically released glutamate and is principally responsible for ensuring that synaptic glutamate concentrations remain low. This process is associated with a significant energetic cost.

We compared protein expression by Western blot analysis in four areas of postmortem brain from patients with schizophrenia and control subjects for several proteins that are often used as controls for Western blot studies: beta-tubulin, actin, glyceraldehyde-3-phosphate dehydrogenase, and valosin-containing protein. We did not detect any differences in expression between subjects with schizophrenia and a comparison group. These results suggest that all four proteins are suitable loading controls for postmortem studies of schizophrenia.
