Active clinical trials for "Arthritis, Rheumatoid"

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 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.

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.

The purpose of this study is to see if supplementation of n-3 polyunsaturated fatty acid (PUFA) can be beneficial for the patients with rheumatoid arthritis.

Studies have shown that people with rheumatoid arthritis (RA) have a higher rate of heart disease than people that do not have RA. we believe this is caused by the inflammation produced by RA.

Evaluation on the amelioration of symptom intensity of the indication and to evaluate drug tolerability.

This multi-center, non-interventional study will evaluate the pattern of usage in clinical practice, efficacy and safety of tocilizumab in patients with rheumatoid arthritis. Patients initiated on treatment with tocilizumab according to the licensed Canadian product monograph recommendations will be followed for 12 months from the start of treatment.

This prospective, observational study will assess the effect of RoActemra/Actemra (tocilizumab) on fatigue in patients with moderate to severe rheumatoid arthritis who have an inadequate response to disease-modifying antirheumatic drugs (DMARDS) or anti tumor necrosis factor (anti-TNF) drugs. Eligible patients receiving RoActemra/Actemra according to the standard of care will be followed for 4 months.

This is an open-label, uncontrolled, observational study in patients with rheumatoid arthritis (RA) who are receiving tocilizumab concomitantly with methotrexate as part of their standard of care.

A review of the literature reveals that very few studies have assessed the potential co-existence of vitamin B12 deficiency due to gastric parietal cell autoantibodies. While Segal et al. in 2004 published a study which found that 49% of patients with RA had vitamin B12 deficiency, no assessment of the etiology or the presence of autoantibodies was made. While Goeldner et al. in 2011 and Datta et al. in 1990 demonstrated that anti-gastric parietal cell antibodies (anti-GPC Ab) were found in <5% to 28% of RA patients respectively, no additional testing was implemented to determine the significance, specifically whether or not the presence of anti-GPC Ab related to vitamin B12 deficiency. The purpose of this study is to determine the prevalence and metabolic significance of anti-GPC Ab in three cohorts: (1) a group of patients with Rheumatoid Arthritis, (2) a group of patients with autoimmune thyroid disease (AITD), and (3) a group of patients with neither RA or AITD. To determine the significance of the presence of anti-GPC Ab, testing of the current serum B12 level along with a metabolite dependent on adequate vitamin B12 levels (Methylmalonic acid) will be tested.
