Filter by:This study aims to analyses time to disease relapse of RA patients if TNF-α inhibitors are being tapered, the predictive factors that are associated with successful taper of TNF-α inhibitors. Also, investigate the effects associated with dose tapering of TNF-α inhibitors.
The combination of methotrexate (MTX) with a biological disease-modifying antirheumatic drugs (bDMARD) is the next step in treatment with MTX monotherapy in rheumatoid arthritis (RA). Estimation of MTX and bDMARD impregnation could be performed with the erythrocyte MTX polyglutamate (MTX-PG) and bDMARD assays before to move to a second bDMARD. In RA patients treated with MTX (prescribed for at least 6 months at a stable dose for at least 3 months) in combination to a first bDMARD (prescribed since at least 3 months), an assay of MTX-PG and bDMARD will be performed in tow subsets of RA according to the level of disease activity. The first subset is active RA defined by a DAS28 (disease activity score 28)>3.2. The second one is RA in clinical remission defined by a DAS28<2.6. The main hypothesis is the association between the low concentration of MTX-PG and the clinical response of RA patients treated with subcutaneous methotrexate injection associated to a first bDMARD. Adherence to MTX will be reviewed by the Compliance Questionnaire Rheumatology (CQR) questionnaire. This assay could be useful to improve MTX management before to move to a second bDMARD.
Study Purpose and Design: A Multi-center, Randomized, Double-blind, Placebo-controlled Study to Evaluate the Safety, Tolerability and Pharmacokinetics of Single Ascending Dose and Multiple Ascending Doses of TJ003234 in Rheumatoid Arthritis Patients.
The objective of a multicenter prospective observational study is to compare effectiveness and safety of biologic disease-modifying antirheumatic drugs and small molecular inhibitors in patients with moderately to severely active rheumatoid arthritis patients who have had an inadequate response or intolerace to methotrexate.
Background: RA may progress with articular and non-articular involvement.Depression prevelance is found to increase for RA patients according to healthy population and to be correlated with pain, decreased quality of life, fatigue and physical disability.BDNF level was found significantly lower in RA patients with depression. Aim of this study is to investigate the variation of BDNF, VEGF, TNF- α, IL-6, IL-1β, irisin and α- Klotho levels following acute exercise. Methods: This study included 45 RA patients and 45 age and sex matched healthy controls. Blood samples from all subjects were taken and centrifuged before and immediately after the exercise intervention.
Background: Patients with inflammatory arthritis (IA), such as spondyloarthritis (axSpA), rheumatoid arthritis (RA) or psoriatic arthritis (PsA) are more prone to physical inactivity but derive specific benefits from regular physical activity. Barriers and facilitators to physical activity (B&F-PA) are key elements and knowledge of their correlation to physical activity is essential for developing interventions to promote physical activity that have a greater likelihood of success. Objectives: primary objective will be to measure the correlation of these B&F-PA to physical activity collected through apps. Secondary objective will be to (I) to quantify physical activity collected through apps in IA patients and (II) to observe the link between physical activity, B&F to physical activity and adherence to treatment. Patients and methods: This is an international, multicentric, cross-sectional study. Patients: From the first of September to the first of February 2020, all patients with definite axSpA, RA or PsA, aged above 18 and able to walk, who have a mobile phone compatible with apps that can track steps, who agree to participate and give his oral informed consent and with ability to read and write in the language of the participating country, seen in outpatient visits in the participating centers, will be asked to participate. The planed inclusion was 200 participants. Data collection: clinical data and information about physical activity and B&F-PA will be entered by rheumatologists during or electronically by patients at the same time point. Questionnaire for B&F-PA: a patient reported questionnaire was recently developed for this study in 2019 based on a systematic review to identify the main B&F-PA. A list of questions was generated from the systematic review reviewed and tested for face validity by 11 experts and confronted to 20 patients with IA through a cognitive debriefing. Physical activity: Physical activity will be measured objectively during the last 7 days by apps already installed by default on the mobile phone of participants and subjectively with the International Physical Activity Questionnaire short version (IPAQ-S). Other outcomes: Stage of exercise behavior change and adherence to treatment will also be collected. Planned analyses: Perceived B&F-PA will be described using frequencies. A score will be calculated for each participant representing the limitations or facilities to perform physical activity. Analysis of the physical activity: The distribution of mean number of steps will be assessed visually for outliers. Univariate analysis will be completed between mean number of steps and gender, age, disease and stages of change. Correlation between mean number of steps and IPAQ-S score will be calculated. Link between physical activity and barriers and facilitators: The link between B&F questionnaire score and mean number of steps will be tested using linear regression. Then multivariate regression including demographic variables, psychological status and disease characteristics will be performed. Outcomes of the study: The expected outcomes of the ImBAIA study are a better understanding of B&F to physical activity in patients with IA and their impact to limit or to favor physical activity. We also expect to observe the level of physical activity of an IA population objectively measured with apps. Finally, a validation was expected to use questionnaire of B&F.
Design: Randomized, double-blind, placebo-controlled study with 4 weeks of treatment with either fiber supplements or placebo. Primary outcome: variation in SCFA between baseline and week 4. Secondary outcomes : variations in gut microbiota, disease activity (DAS28, RAID), immune cells (regulatory T and B cells, Th17) and heart-rate variability. Population: 29 patients with rheumatoid arthritis treated with only csDMARDs and a moderate disease activity will be recruited in each arm and 29 controls with mechanic disease (osteoarthritis, tendinitis). Collection: Blood, feces, disease activity and heart rate variability will be collected at baseline and week 4.
Rheumatoid arthritis is a chronic systemic inflammatory and autoimmune disease, characterized by disordered immunity, not regulated cytokines and inflammatory infiltration of the synovial joints. It is the most common inflammatory erosive poly arthritis affecting around 0.5-1% of the worldwide population which leads to joint damage and disability

The current situation of Sars-Cov-2 pandemic generates fears in the general population. Among patients receiving long-term immunomodulatory drugs, especially in the context of auto-immune diseases, there may be legitimates interrogations about the appropriateness of continuing treatment, without modification, in the current context. Most patients with Juvenile Rheumatoid Arthritis benefit from long-term immunmodulatory therapy (DMARD - disease modifying anti-rheumatic drug), more or less combined with regular use of non-steroidal anti-inflammatory drugs (NSAIDs) or corticosteroids.The present study will characterize this issue by defining the proportion of patients whose usual treatment of Rheumatoid Arthritis has been modified in relation to the actual sanitary crisis.
