Active clinical trials for "Arthritis, Rheumatoid"

Rheumatoid arthritis is the most common rheumatic disease with symptomatic morning stiffness which entails a quite essential restriction in the everyday life and in the life quality. This observational, uncontrolled, multicentric study is aimed to assess the improvement in the activity status or QoL of subjects with RA being treated with the Tempus tablet.

The AGIL study was designed to evaluate the effectiveness and safety of adalimumab over 5 years in routine daily clinical practice in Germany, with a focus on the impact of therapy on employment-related outcomes.

This is an observational, non-interventional, non-comparative, post-authorization safety study to evaluate efficacy and long-term safety of Cimzia in adult patients with RA in need of treatment with a biological product.

To stimulate collaborative efforts of federal funding agencies, voluntary health agencies, professional organizations and industry partners to enable creation of a large, sustainable database and repository to better understand the molecular basis of treatment and rapidly accelerate translational research in RA.

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.

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

This study will assess the rates of serious adverse events and death in adult rheumatoid arthritis patients treated with etanercept over the long-term in real-life clinical practice. It will also assess whether there is any difference in the rate of serious adverse events in patients trated with etanercept in comparision to patients treated with conventional disease-modifying anti-rheumatic drugs (DMARDs). The study will in addition quantify the efficacy of etanercept in this population by assessing the rates of important clinical outcomes such as changes in disease activity and disability/functioning.

The purpose of this study is to characterize CD86 receptor occupancy in subjects with rheumatoid arthritis (RA) receiving abatacept.

This observational study will assess the efficacy and safety of RoActemra/Actemra (Tocilizumab) in smoking versus non-smoking patients with rheumatoid arthritis. Data from patients treated in routine clinical practice with intravenous RoActemra/Actemra will be collected for 12 months each.

Pertussis is an acute respiratory infection caused by Bordetella pertussis. Rates of recent B. pertussis infection between 8%--26% have been reported among adults with cough illness of at least 5 days duration who sought medical care. The CDC recommends vaccinating patients aged 15 to 64 years old, once in 10 years. Although acellular vaccines such as BOOSTRIX have been evaluated in healthy population, the safety and efficacy of this vaccine in patients suffering from rheumatic diseases have not been established. Study population : 50 Rheumatoid Arthritis (RA) patients and 5 healthy controls Evaluation : the evaluation will be performed on week 0 and 4-6 weeks later. In terms of safety, the patients will be evaluated according to the Disease Activity Index (DAS). Blood will be drawn at each visit at tested for humoral response to tetanus and pertussis.
