Active clinical trials for "Arthritis, Rheumatoid"

The efficacy of vaccination against influenza in patients with rheumatoid arthritis has been assessed using humoral response. However, the cellular immunity is another important pathway of response to vaccination. The purpose of this study is to evaluate the degree of cellular immunity response to influenza vaccination. Patient with rheumatoid arthritis and healthy controls will participate in this study , will undergo a clinical evaluation the day of vaccination and 4 weeks after. The humoral and cell immunity response will be assessed the day of vaccination and 4 weeks later

Background of the study: Rheumatoid Arthritis (RA) is an autoimmune disease. There are four stages of the disease: Synovial inflammation Swelling of synovium Pannus formation Advanced bone and cartilage destruction Currently, there is no cure for RA, making the disease a chronic condition. RA is more prevalent in elderly and women. With medication it is possible to delay the onset of complications. Over the last decade, the treatment of RA has changed. Where treatment was palliative until pain medication was ineffective, the treatment is now more aggressive with early administration of disease modifying drugs (DMARDs). The treatment for RA is staged. First, the patient receives generic, low-cost drugs. If this treatment becomes ineffective, the treatment is adjusted with different and usually more advanced drugs. Biologics are a category drugs that are considered most advanced and most expensive. For effective treatment, there are two unmet needs. A tool to aid early diagnosis, as this allows early treatment and delay of complications and physical restrictions for patients. A safe, simple and cheap tool to monitor disease progress to allow traceable, operator-independent informed decisions on treatment adjustments. Non-invasive optical methods offer several advantages over existing modalities. Optical contrast can be related to physiological parameters in the body, such as blood concentration and oxygenation. At relevant wavelengths and intensities, optical radiation is completely harmless. The cost of optical methods is low compared to other modalities. An important application, where optical methods can help diagnosis and treatment is detection of inflammation of joints in patients suffering from rheumatoid arthritis (RA). Due to the highly scattering nature of tissue, non-invasive optical methods for medical imaging are limited to the extremities of the human body. For application in joint diseases, this is acceptable, because imaging of hands can provide sufficient clinical information. Objective of the study: Primary objectives: This is a retrospective, nonrandomized controlled observational study, conducted in a single center to evaluate the potential of optical attenuation measurements to establish disease activity for rheumatoid arthritis patients. Secondary objectives: Establish parameters from transient optical transmission measurements of the joint that relate to clinical evaluation results of individual joints Evaluate relation between disease activity (DAS-28 score) and the optical attenuation spectra of the fingers of a patient. Study design: This is a cross sectional, nonrandomized controlled observational study, conducted in a single center to evaluate the potential of optical attenuation measurements to establish disease activity for rheumatoid arthritis patients. Study population: The subject population will be patients visiting the Regionaal Reuma Centrum Eindhoven for rheumatoid arthritis. Patient visiting this center will represent a cross section of RA patients that are taken care of in an outpatient setting. Primary study parameters/outcome of the study: Primary endpoint is a successful measurement of optical attenuation of a joint and the part of the finger next to the joint before, during and after two consecutive restrictions of venous blood flow by means of a pressure cuff. Secondary study parameters/outcome of the study (if applicable): Secondary endpoints are unsuccessful measurements related to early termination of the measurement related to patient discomfort or safety and equipment or software failure.

This study will test the palatability of several different CP-690,550 oral preparations in trained product tester healthy volunteers.

The aim of this study is to examine the associations between inflammatory disease activity and endothelial function in rheumatoid arthritis (RA) and spondyloarthritis patients treated with methotrexate and Tumor Necrosis Factor alpha (TNFalpha)inhibitor in combination or methotrexate or TNFalpha-inhibitor alone. Further, to look for improvement in endothelial function, and decrease in bone and cartilage destruction during treatment with the combination therapy of TNFalpha-inhibitor and methotrexate in RA and Psoriatic Arthritis (PSA) patients. Last, examine the TNFalpha inhibitors influence on endothelial function and levels of bone and cartilage markers in patients with Ankylosing Spondylitis (AS).

This prospective, observational, multicenter study will assess the efficacy and safety of RoActemra/Actemra (tocilizumab) on the use of glucocorticoids in patients with moderate to severe rheumatoid arthritis and an inadequate response to previous disease-modifying antirheumatic drugs or anti-TNF. Data will be collected for 36 weeks.

This observational study will evaluate the efficacy and safety of RoActemra/Actemra (tocilizumab) in clinical practice in patients with moderate to severe rheumatoid arthritis. Data will be collected from patients for the 12 months following the first infusion of RoActemra/Actemra.

The purpose of this study is to examine the association with EBV infection, monitor the occurrence of lymphoma and assess lymphoma risk in patients with rheumatoid arthritis and/or Crohns disease and you have taken infliximab.

This postmarketing surveillance study will evaluate the safety profile of Enbrel (etanercept) in an Indian population. It will provide surveillance on a currently approved indication for Enbrel of reducing symptoms and inhibiting the progression of structural damage in patients with moderately to severely active rheumatoid arthritis.

The specific aim of this study is to compare the rate of negative work role events in individuals with rheumatoid arthritis compared to healthy controls.

The purpose of this study is to determine in Australia what effect rheumatoid arthritis has on quality of life, and also to determine the costs that are associated with having rheumatoid arthritis.
