Active clinical trials for "Arthritis, Rheumatoid"

Evaluation of serum KL6 level in rheumatoid arthritis-associated interstitial lung disease (RA-ILD).

The goal of this open label multicenter randomized controlled pragmatic superiority trial is to investigate the optimal treatment/tapering strategy with rituximab for patients with rheumatoid arthritis. The main questions it aims to answer are: What is the optimal treatment/tapering strategy for rituximab in patients with rheumatoid arthritis in terms of reducing patient reported disease impact? What is the optimal treatment/tapering strategy for rituximab in patients with rheumatoid arthritis in terms of therapeutic efficacy? Participants will be randomized to one of two study arms: Tapering based on disease-activity guided dose reduction (experimental arm) Tapering based on interval prolongation (active comparator arm)

Biotherapy present specifics risks that patients must know and learn to manage. A national survey has been carried in this study to evaluate patients safety skills. (wording: " cross study of safety skills of 677 patients treat by biopharmaceuticals for an inflammatory rheumatism). This survey has allowed showcasing patients difficulties in managing their treatment, including for those under subcutaneous biotherapy. More than 60% patients interviewed doesn't know symptoms to bring them to consult and mainly postpone to their injection. The aim of this study is to prove that nursing consultation can allow the patient to become independent in treatment management and thus avoid occurrence of adverse event.

The prevalence of Sjogren's syndrome (SS) in rheumatoid arthritis (RA) patients varies from 3.5 to 31%. Between 30% and 90% of patients with (RA) have dry eye and/or mouth syndrome. To date, no studies have assessed whether RA patients have echostructural changes in their salivary glands suggestive of SS and the factors associated with these changes.The aim of this study is to investigate if there are changes in the echostructure of the salivary glands of RA patients, especially in patients with dry syndrome.

There is no treatment that could utterly cure Rheumatoid arthritis (RA), but the disease is mainly improved by conventional disease-modifying anti rheumatic drugs. Methotrexate and biological DMARDs as JAK-STAT inhibitors may be used to control and delay the progression of the disease and improve the quality of lives of patients. However, DMARDs have deleterious effects on human health. Several natural components have JAK-STAT inhibitory effect such as Boswellic acid (Boswellia serrata extract), Glycyrrhizin (Glycyrrhiza glabra extr.) and Apigenin (Chamomile extr)

This clinical trial will investigate the effects of capsules containing stool from healthy donors, called fecal microbial transplant (FMT), in rheumatoid arthritis patients.

Although rheumatoid arthritis (RA) treatments are very effective in reducing inflammation, chronic pain persists in 20 to 30% of patients. The intestinal microbiota can participate on the pain pathways and a decrease in Faecalibacterium has been associated with chronic pain and chronic fatigue. RA patients have an altered gut microbiota or dysbiosis. Among the bacteria that are most often differentially represented between RA and control, Faecalibacterium, was also found less abundant in RA patients. The composition of the gut microbiota has never been evaluated in relation to the clinical phenotype of RA patients and in particular to the presence of a diffuse pain. In this study, investigators will test whether the gut microbiota of RA patients, and in particular the decrease of Faecalibacterium, would promote pain sensitization phenomena, and thus, chronic pain despite the control of joint inflammation.

The goal of this case control observational study is to asses anxiety, sleep, depression and quality of life in rheumatoid arthritis patients The main aims are: asses anxiety, sleep, depression and quality of life in rheumatoid arthritis patients their relation to disease activity we will compare rheumatoid arthritis patients to healthy subjects.

An Observational, Prospective Cohort Study to Evaluate Safety and Efficacy of RemsimaTM in Patients with Rheumatoid Arthritis.

Hypothesis: SLE and RA increase risk of myocardial infarction (MI, heart attack). Immune reactants in the circulation of SLE patients downregulate cholesterol efflux proteins 27-hydroxylase and ABCA1 and upregulate scavenger receptor CD36, thus encouraging cholesterol accumulation. Adenosine A2A receptor agonist or statin treatment of cells exposed to SLE plasma (or immune complexes or cytokine-enriched plasma fractions from SLE patients) may ameliorate inflammatory properties of their plasma, lessening its atherogenic potency. Rationale: SLE and RA plasma contain components not present in significant levels in normal plasma that could, individually or acting together, affect 27-hydroxylase, ABCA1 and CD36 expression. Candidate components include autoantibodies, immune complexes, and various cytokines. Statins reduce major cardiovascular events and death. Modulation of adenosine signaling participates in regulation of 27-hydroxylase and ABCA1. As a potential preventative and therapeutic approach to atherosclerotic cardiovascular disease, the investigators evaluate the effect of A2A receptor agonists and statins on atherogenic parameters in SLE and RA plasma. Experimental Plan: Quantitate 27-hydroxylase and several other proteins involved in cellular cholesterol uptake and excretion in THP-1 monocytes/macrophages and HAEC after exposure to plasma and plasma components from SLE patients (and controls) ± lipid loading with acetylated LDL with/without addition of A2AR agonist, statin, or both. Determine relative impact of immune complexes and cytokines on expression of proteins involved in cholesterol flux. Determine levels of proteins involved in cellular cholesterol influx/efflux in peripheral blood mononuclear cells isolated from RA, SLE and psoriatic arthritis patients and normal controls at baseline, then following incubation in culture media alone or with statin, adenosine A2A agonist or both statin + A2AR agonist.
