Active clinical trials for "Arthritis"

Blood test in Rheumatoid Arthritis (RA) patients with good response to anti-Tumor Necrosis Factor (anti-TNF) and in patients with moderate or non-response will be done in the month following the evaluation of clinical response to therapy. Isolation of mononuclear cells and purification of monocyte by negative selection. Cell culture of monocyte in presence or not of anti-TNF for 24 hours and analyze of CD36 (cluster of differentiation antigen 36) expression (principal outcome). For secondary outcomes analyze monocyte phenotype, NRF2 nuclear translocation, and clinical data of patients.

Influenza, a vaccine-preventable respiratory disease, is ranked 8th among the causes of death in the Canadian population. Among rheumatoid arthritis (RA) patients, the incidence of both seasonal influenza and serious influenza-related illness (IRI) are increased. Despite being a high priority group targeted for vaccination, the diagnosis of RA and other patient-specific factors (i.e. older age, treatment, current smoking) are linked to impaired vaccination responses. Thus the burden of influenza among people with RA is disproportionally high, and interventions to improve responses to influenza vaccination are urgently needed. Strategies to optimize protection in another vulnerable group, the elderly, include the use of quadrivalent vaccines, higher antigen doses, and adjuvants. A high-dose, trivalent, inactivated influenza vaccine (HD-TIV) has recently been shown to have a similar safety profile to standard dose vaccine (SD-TIV) with improved immunogenicity and protection in adults ≥65 years of age. Whether or not analogous strategies to improve responses to influenza vaccine will enhance protection in people with RA is unknown. The investigators hypothesize that the use of the HD-influenza vaccine will improve vaccine-induced protection (i.e. seroconversion and seroprotection) in people with RA compared to SD-influenza vaccine. The investigators propose to conduct a stratified, randomized, modified double blind, active-controlled trial to assess immune responses to two commercial influenza vaccines containing different antigen doses in individuals with RA.

The purpose of this research study is to evaluate if a weight loss intervention will improve your rheumatoid arthritis disease activity.

This study will examine the benefits of a monitored physical activity program for participants with rheumatoid arthritis (RA) or psoriatic arthritis (PsA) using a wearable activity device (e.g.fitbit). The goals of this pilot study are to examine 1) whether an incentive is better than no incentive in maintaining an increased level of physical activity and 2) the benefits of physical activity on patient reported disease activity in inflammatory arthritis.

Aim: To describe 1) The use of TNF blockers monotherapy in early arthritis in daily clinical practice in France 2) To evaluate symptomatic, structural efficacy, and retention rate over 5 years of TNF blockers monotherapy 3) To evaluate predictive factors for TNF blocker response monotherapy Type of study: Observational cohort study using cross-section and longitudinal data. Description of the project methodology Patients: All patients in the ESPOIR cohort (multicentre French cohort study of early RA).A sub-analysis will be conducted among patients satisfying the ACR-EULAR 2010 criteria. Data collected: Patient characteristics, Clinical data regarding RA and related pathologies, Characteristics of treatments received The analysis will be conducted using data collected at baseline, 6, 12, 18, 24, 36, 48, 60 months. Analyses: Frequency of use of TNF blockers monotherapy: we will calculate the % of patients initiating TNF blockers monotherapy (Kaplan-Meier method), and we will describe the type of TNF blocker, the route of administration, the dosage, and the place of the TNF blockers monotherapy in the treatment strategy during the first 5 years. Identification of potential predictive factors for initiation of TNF blockers monotherapy: a survival curve (Kaplan-Meier) will be performed. The baseline characteristics of the patients with regard to the initiation of TNF blocker monotherapy during the first 5 years of the disease will be compared by univariate analysis and Log-rank test will be performed in all variables. A stepwise multivariate analysis (Cox analysis) will be performed. Therapeutical effect: we will calculate the retention rate over time, and will compare the changes in different variables in the group of patients who have received TNF blockers monotherapy matched (using a propensity score) to 1,2 or 3 patients who have received TNF blockers in combination with synthetic DMARDs. We will assess and compare DAS28 and HAQ at short term (after at least 8 weeks of treatment) and long term (last available visit) in groups. The structural efficacy was evaluated by the radiographic progression at last available visit. We will identically estimate the drug effect depending on the TNF blocker used, by calculating the retention rate and comparing DAS28 at short term and long term. Identification of predictive factors for TNF blocker monotherapy response: To evaluate the impact of baseline demographics and disease conditions on the DAS28 and HAQ response during the first 5 years will be compared by univariate and multivariate analysis. Expected results: Increase knowledge on the use of TNF blocker monotherapy, its efficacy and retention rate, and on predictive factors for TNF blocker monotherapy response in early RA patients.

This multi-center, observational, retrospective-prospective cohort study will investigate the safety of rituximab (MabThera) by collecting data from daily clinical practice on the use of rituximab and its relative clinical impact, particularly with regard to adverse events. Data from each patient will be collected over 24 months after enrolment in the study. Target sample size is up to 325 patients.

The purpose of this study is to compare condition oriented whole person Health Coaching along with the provision of decision aids to decision aids without condition oriented Health Coaching to neither condition oriented health coaching nor decision aids on medical cost, preference sensitive surgeries and measures of subject knowledge, decision process and decision quality.

This observational study will evaluate the dosage patterns, safety and efficacy of RoActemra/Actemra (tocilizumab) in clinical practice in patients with moderate to severe rheumatoid arthritis who have not responded or are intolerant to at least one disease-modifying antirheumatic drug (DMARD) or TNF inhibitor. Data will be collected from each patients for 12 months.

This observational study will evaluate the presence and evolution of fatigue on treatment with RoActemra/Actemra (tocilizumab) in patients with moderate to severe rheumatoid arthritis who have an inadequate response to at least two DMARDs (one of them methotrexate) or to anti-TNF treatment. Patients initiated on treatment with RoActemra/Actemra (8 mg/kg intravenously every 4 weeks) with or without methotrexate will be followed for 4 months.

This observational study will evaluate the safety and efficacy of tocilizumab in participants with active moderate to severe RA and an inadequate response to non-biologic DMARDs. Data will be collected from each eligible participant initiating tocilizumab treatment over 6 months.
