Active clinical trials for "Arthritis, Rheumatoid"

The objective of the proposed study is to assess the role of smoking and complex gene-smoking interactions in two understudied Rheumatoid Arthritis (RA)groups.

The main objective of this PMS study was to monitor and assess the safety of Mobic® intramuscular injection (7.5mg ~ 15mg, q.d.) up to 3 days (in case of need for prolonged treatment, switch to Mobic® capsule therapy was possible) in Korean patients with osteoarthritis and rheumatoid arthritis.

The objective of the observational study is to examine the effect of MOVALIS (Meloxicam) therapy on Health Related Quality of Life (HRQoL) in the diverse region of Central and Eastern Europe. The Medical Outcomes Study 12 Item Short Form Health Survey version 2 (SF-12v2) will be used as the instrument to measure any change in physical wellbeing (Physical Component Summary, PCS) and mental wellbeing (Mental Component Summary, MCS) of patients following MOVALIS (Meloxicam) therapy.

The present survey was conducted to evaluate the effectiveness and safety of treatment with adalimumab during the 52-week period following completion of the treatment period in Study NCT00870467 (M06-859) in participants who continued treatment with adalimumab for 52 weeks.

The main objective of this study was to determine the ability to maintain response after discontinuation of adalimumab treatment and the secondary objective was to determine radiographic progression in participants participating in the study, including the percentage who displayed minimal progression.

Rheumatoid arthritis (RA) is an inflammatory form of arthritis that causes joint pain and damage. RA attacks the lining of the joints (synovium), causing swelling that can result in aching and throbbing, and eventually deformity. Even though there have been many advances in the treatment of RA, psoriatic arthritis (PsA), and other inflammatory arthritis, doctors still do not know what causes this inflammation in joints. It is likely that RA occurs as a result of a complex combination of factors, including a person's genes; lifestyle choices, such as smoking and diet; and things in a person's environment, including bacteria or viruses. This study investigates the hypothesis that bacteria living in a person's mouth and/or intestinal tract are responsible, at least in part, for the development of Rheumatoid Arthritis. The investigators believe that by killing those bacteria with antibiotics, they might be able to understand how the immune system works and, maybe, what causes RA.

This is a study evaluating the long-term safety of infliximab (Remicade)

BACKGROUND. Polymorphisms occur in several genes encoding key enzymes in the folate pathway may affect drug metabolism in patients with rheumatoid arthritis. Whether these genetic variations contribute to differential responses to antifolate drug in patients with rheumatoid arthritis (RA) remains to be investigated in the Taiwanese population. OBJECTIVE. The goal of the present study is to investigate the interactions between genetic variations in folate genes and the efficacy/side effects of anti-folate disease-modifying anti-rheumatic drug in Taiwan. DESIGN. A cross-sectional study involving patients with RA were enrolled from TCVGH. Disease activity, drug efficacy and associated side-effects were assessed. Genotypes in folylpoly-gamma-glutamate synthetase and reduced folate carrier were determined by RFLP or pyrosequencing.

Rheumatoid arthritis (RA) and ankylosing spondylitis (AS) are characterized by chronic systemic inflammation and share common pathogenic pathways. In both diseases, cytokines like TNF (tumor necrosis factor) and interleukin (IL)-17, known for their pro-inflammatory and osteoclastogenic effects, are relevant players, however, while RA is characterized by bone erosions, AS favors bone overgrowth. Understanding this paradox may hold the key for a better management of both diseases. Our hypothesis is that there are differences in the cellular environment and intracellular signaling between AS and RA. To test this hypothesis we will evaluate the cytokine milieu, the kinetics of bone cells differentiation and their activity in untreated and immunosuppressed RA and AS patients. We will also perform the same observations in patients exposed to targeted treatments.

This prospective, multi-center, observational study will evaluate factors influencing the use of tocilizumab (RoActemra/Actemra) as monotherapy in rheumatoid arthritis patients in real life setting. Data will be collected from participants for 12 months following initiation of tocilizumab treatment.
