Active clinical trials for "Arthritis"

The purpose of this study is to compare the incidence rates of infection, malignancy and death among patients with rheumatoid arthritis who are treated with abatacept and those who are treated with other anti-rheumatic medications for rheumatoid arthritis.

This study is the multi-center, open and cross-sectional study of RA remission in Asia Pacific region. The objectives is to explore remission rate of RA patients in different countries in the Asian-Pacific area using different criteria of remission (DAS28, CDAI, SDAI, ACR/EULA remission criteria, RAPID3 and Clin28) and investigate the associated factors of remission in RA patients.

Multicenter, prospective, observational study for evaluating if circulant rheumatoid factor, cyclic citrullinated anti-peptide anti-bodies and albumin can be used as potential predictors in the response to the treatment with anti-TNF in patients with rheumatoid arthritis after 24 weeks of treatment.

To observe the relationship between the activity of rheumatoid arthritis and popliteal/epitrochlear lymph node morphology and the drainage of hand/foot superficial lymphatic vessels

To detect accuracy of serology in diagnosis of temporomandibular joint arthritis.

There is a correlation between the CD55, CD59, CD35 and CD46 expression on B lymphocytes of patients before and after treatment with rituximab and the level of depletion and repopulation time for these cells. The theoretical rationale of the study assumes that the correlation, if any, will be a negative correlation. However, the hypothesis of positive correlation (two-tailed test) will also be tested.

The purpose of this study is to evaluate whether the risk of serious infections in rheumatoid arthritis patients with tocilizumab is higher than in those with tumor necrosis factor inhibitors using the nationwide real-world data.

The Norwegian JIA Study (NorJIA) is a prospective, longitudinal, multicenter, observational study of 250 children with juvenile idiopathic arthritis (JIA) and 250 healthy controls, attending the three Norwegian university clinics in Bergen, Tromsø, or Trondheim. The study will run over 5 years, and include extensive clinical, laboratory, radiological and oral examinations at baseline and after 2 years follow-up. There will be a special focus on the jaw (temporomandibular joints) with extensive imaging and clinical examination, aiming at establishing scoring systems for active and chronic disease and growth disturbances. Another focus is to study mouth and teeth problems, such as caries and gingivitis, and look for predictors of poor oral health in children with JIA compared to health peers. As chronic inflammation, reduced physical activity and certain anti-inflammatory drugs can be detrimental for bone strength and development, the investigators also want to study the bone health of children with JIA, and look for predictors of poor bone mineral density. The results of the study may contribute to better diagnostics of inflammatory processes, earlier detection of poor oral or bone health, and thereby point to possible prevention strategies to increase quality of life for children with JIA in the future.

Over the last decades, total ankle replacement (TAR) emerged as a reliable treatment option in end-stage ankle osteoarthritis (OA) while preserving motion and physiological load. The Cadence™ is a fourth-generation, two-component, fixed-bearing implant with minimal tibial and talar resection. It has been in clinical use since July 2016, the purpose of this study was to compare the clinical outcome and radiological outcomes of total ankle arthroplasty with use of the Cadence™ prosthesis at St. Michael's Hospital.

The high resolution chest scan is the gold standard for the screening of interstitial lung disease, but this remains an onerous examination, and irradiating. Ultrasound could be used to detect these disorders with a very good sensitivity and specificity. This exam offers the advantage of being non radiating, inexpensive, and accessible to the rheumatologist who already uses it in their daily practice. The investigators want to assess the lung ultrasound performance compared with the gold standard. Patients will be included during a regular follow-up consultation with their referent rheumatologist. If there is an indication of first line biotherapy or targeted therapy the doctor will propose to the patient to participate in the study, give him the information leaflet, collect orally non-opposition, and will complete a survey for evaluation of the general health and potential risk factors for interstitial lung.
