Ultrasonography as a Biomarker in Early Rheumatoid Arthritis
Rheumatoid ArthritisThis is a prospective, observational study designed to look at ultrasound images of the joint at baseline and over time, and investigate whether there is a correlation between ultrasound images and progression of disease. The researchers wish also to see if ultrasound can be used as a tool to predict progression of Rheumatoid Arthritis in patients with early disease who have not taken biologics therapy. In addition, the researchers wish to investigate whether peripheral blood "biomarkers"can be identified that predict the progression of erosive disease in early rheumatoid arthritis, with the intention of testing the most promising biomarkers in future clinical trials.
Identification of Genes Associated With Lung Disease in Patients With Rheumatoid Arthritis
HealthyPulmonary Fibrosis1 morePulmonary fibrosis (PF) is a condition in which the lungs of a patient become scarred and fibrous. It has been known to occur in as many as 40% of patients diagnosed with rheumatoid arthritis (RA). The cause of the pulmonary fibrosis in patients with RA is unknown. Data gathered from previous research studies suggest that genetics may play a role in the development of PF in patients with rheumatoid arthritis. However, the actual genetic factors involved in the disease process have not been identified. The goal of this study is to identify the genetic markers in patients with pulmonary fibrosis and rheumatoid arthritis.
The Pathogenesis of Inflammatory Synovitis: A Study of Early Arthritis
ArthritisArthritis5 moreThis study will evaluate patients with inflammatory forms of arthritis within the first year of onset. The study will attempt to clarify factors that may predict disease course such as evolution into rheumatoid arthritis (RA) or other chronic inflammatory arthropathies. Synovial biopsies and synovial fluid will be obtained to search for microbial agents and other initiating and modulating factors that may be most readily distinguished early in the disease and to determine the stage of disease at which certain immunologic and hormonal changes become evident. The study will also search for genetic and other features that may be associated with specific forms of inflammatory arthropathies that might predict the subsequent clinical disease course or response to different agents used in treatment of RA, Reiter's syndrome and other types of chronic inflammatory arthropathies.
Enthesis Differences in Rheumatoid Arthritis and Axial Spondyloarthropathy
Axial SpondyloarthritisRheumatoid Arthritis2 moreThe aim of this study is to investigate the sonographic differences in entheses in patients with Rheumatoid arthritis and Axial Spondyloarthropathy.
Is Ultrasound Remission a Real Remission? Does Ultrasound Permit to Achieve and Maintain the Remission...
Rheumatoid ArthritisRemissionRemission is nowadays an achievable objective for Rheumatoid Arthritis (RA) patients thanks to a large choice of therapies, early treatment and tight control (30% relapse). Ultrasound (US) driven-therapy, complemented with a clinico-biological follow-up, may improve the prognosis of RA in remission by increasing the duration of sustained remission and by preventing radiographic structural progression. The tested hypothesis is: The US coverage of RA allows to increase the duration of sustained clinical remission.
Study of the Treatment of Algerian Patients With Early Rheumatoid Arthritis
Rheumatoid ArthritisThis non-interventional, descriptive, cross-sectional and multicenter study will examine the treatment of rheumatoid arthritis progressing for less than two years in the Algerian population. Current drug therapy as well as disease status and patient function will be assessed.
Pain Evaluation in Rheumatoid Arthritis
Rheumatoid ArthritisRheumatoid Arthritis (RA) is an inflammatory chronic rheumatism where the pain remains the priority domain of improvement for the patients instead a good control of the inflammatory disease by treatments, even biotherapeutics . Some studies show that less than 50 % of the patients is satisfied by the care of the pain, whereas the criteria of evaluation of the RA improve under treatment. The chronic pain, is a complex and multifactorial subjective phenomenon requiring a multidimensional evaluation, while the current criteria of follow-up of the RA (DAS28, ACR criteria) investigate the pain in a single dimension that is the pain intensity. So, the investigators do not arrange explanation for this observed dichotomy between the improvement of the clinical and biological inflammatory criteria of the RA and on the other hand the persistence of pain. On the other hand, the interleukin (IL)-6, IL-17 and IL-33 are cytokines occurring in the physiopathology of RA and probably in the pain processing according to recent data of the literature. The aim of this study is: to assess the multidimensional origin of the pain in RA patients by means of questionnaires to look for a possible correlation between the serum level of cytokines and pain.
Physical Activity in Patients With Rheumatoid Arthritis Treated With Adalimumab in Routine Clinical...
Rheumatoid ArthritisThe purpose of this study was to evaluate physical activity and its changes in participants with rheumatoid arthritis (RA) who were treated with adalimumab therapy in clinical practice.
Perioperative Flare in RA: Characterization of Clinical and Biological Features
Rheumatoid ArthritisResearchers at the Hospital for Special Surgery are trying to learn more about post-operative rheumatoid arthritis flare (RA). This study hopes to understand RA flare after total joint replacement surgery and what the result of flaring is for patients over the 6 weeks post operation. Through this study we aim to describe rates, characteristics, and risk factors of RA flare within 6 weeks of total hip arthroplasty (THA) and total knee arthroplasty (TKA)
