Active clinical trials for "Arthritis"

This is an observational study to estimate the proportion of patients diagnosed with RA visiting a medical internist in a general hospital in Korea who are candidates for anti-TNF α therapy.

The purpose of this prospective clinical data collection is to document the performance and clinical outcomes of the Regenerex™ Tibial Tray.

The study is a cross sectional, epidemiology study of disease severity for rheumatoid arthritis, psoriatic arthritis and ankylosing spondylitis in four geographic regions in Australia (Illawarra, Sutherland, Hunter Urban and Hunter Rural).

The goal of the project is to study the risk of coccidioidomycosis (valley fever) in patients receiving anti-TNF and other biologic agents for inflammatory arthritis in Tucson, Arizona.

The primary purpose of this study is to evaluate a computer-based tool on the clinical management of patients with rheumatoid arthritis in Spain.

One of the biggest challenges in caring for patients with Rheumatoid Arthritis (RA) and Juvenile Rheumatoid Arthritis (JRA) is quantifying the degree of disease activity in any given joint. We have built a prototype device using well-established sensors to rapidly quantify surface swelling and heat in arthritic joints. The goal of our studies is to test the hypothesis that this Imager can improve the clinical assessment of arthritis.

Septic arthritis is a frequent, potentially disabling and/or life-threatening disease. To diagnose a septic arthritis is a complex procedure, first because of numerous differential diagnoses (such as crystal arthritis), second because of poor sensitivity of initial gram staining (for example after untimely antibiotic therapy). This protocol will use SELDI-TOF as a tool to analyse joint fluid of patients with various acute, polymorphonuclear-rich arthritis, as to determine specific and sensitive new biomarkers of a septic origin. Such biomarkers will allow rapid diagnosis of septic arthritis in the first hours of admission.

Juvenile idiopathic arthritis (JIA) is often associated with chronic anterior uveitis. Presence of vision threatening complications may indicate immunosuppressive therapy. In this study, the experience with cyclosporine A (CsA) as mono- or combination-therapy is analyzed.

The purpose of this study is collection and analysis of information pertaining to pregnancy outcomes in women exposed to infliximab during pregnancy, relative to the background risk in similar but non-biologic exposed patients; and information pertaining to health status, during the first year following delivery, of infants born to women following prenatal exposure to infliximab and their unexposed counterparts.

This protocol will examine blood, synovial fluid and synovial tissue from patients with rheumatoid arthritis and other chronic inflammatory joint diseases to study genetic and immunologic factors involved in the cause, development and progression of these conditions. Synovial fluid is the lubricating fluid in joints. The synovial membrane is a delicate tissue lining the inner surface of joints, which, in arthritic conditions, thickens and becomes infiltrated with various types of cells. Patients with rheumatoid arthritis and certain patients with other forms of arthritis may be eligible for this study. Those enrolled will be followed periodically for follow-up and disease evaluation. They may undergo the following procedures: Synovial fluid aspiration, when medically indicated (for example, for joint swelling and inflammation). For this procedure, an area of skin around the joint is numbed with an anesthetic, and a needle is inserted into the joint to withdraw a small fluid sample. Periodic blood sampling, not to exceed 450 milliliters (15 ounces) during any 6-week period, for genetic studies of rheumatoid arthritis. The samples are usually taken at the same times that synovial fluid is withdrawn. Synovial tissues, collected by needle biopsy or during surgical procedures for arthroscopy (examination of the interior of the joint and repair of the joint) or total joint replacement. For the needle biopsy, the skin over the biopsy site is washed and anesthetized. A needle is inserted and fluid is aspirated. The biopsy needle is then inserted through the outer needle and a tissue sample is suctioned. Patients who qualify for other research studies may be invited to participate.
