Rheumatoid arthritis (RA) is an autoimmune and sistemic disease,characterized by joint sinovitis and the production of autoantibodies (Ab). The Ab against citrullinated peptides (ACPA) are the most specific (92-98%), and high sensitivity (75-81%) and they are of prognostic value. ACPA are already in the beginning of the disease in most cases, having been found years before its onset. Recent studies have suggested that ACPA may have a role in perpetuating inflammation, in the generation of bone erosions and in pain in RA. Citrullination is a post-translational modification mediated by the PAD, which transforms an arginine into a citrulline. In vivo, this enzyme acts in proinflammatory environments. Despite being widely studied, none of the natural citrullinated substrates have been shown to be the triggering and/or perpetuating factor in the response of B cells in RA, understanding this response as the production of ACPA. In fact, the most specific and sensitive commercial test for the detection of ACPA uses synthetic peptides protected by a patent. In the other hand, the genetic factor that most increases susceptibility to develop RA is a shared sequence of aminoacids (QKRAA, QRRAA i RRRAA), in the HLA-DRB1 gene, known as the shared epitope (SE). Also, SE, confers prognostic value, and is associated with the presence of ACPA. These SE sequences contain arginines (R), which are susceptible to be citrullinated by the PAD enzyme. We propose the hypothesis that citrullinated SE act as an antigen capable of activating the inflammatory response mediated by B and T cells in RA. The recognition of an HLA as a foreign one, would originate an answer of alloimmune type, not valued to date. The objective of the study is to test the immune response mediated by B cells and T cells, in cases and control samples, through an in vitro model that confronts them with peptides containing the citrullinated-SE sequence. In addition, we will evaluate the association between these results with the clinical features of cases (RA included in the study). Their role as a biomarker, as well as their potential to improve the tests currently available to detect ACPA will be explored.
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.
Rheumatoid Arthritis (RA) is an autoimmune disease that results in a chronic inflammatory disorder that may affect many synovial joints, and may cause serious disability. It has been confirmed that Tripterygium Wilfordii has effects of anti-inflammatory, immunosuppressive and cartilage protection. This is a multicenter ,double Blind, randomized study to evaluated the efficacy and safety of Tripterygium Wilfordii in treating of patients with rheumatoid arthritis (RA) and establish a prediction model for Tripterygium Wilfordii response of rheumatoid arthritis (RA).
The study aims at determining adherence rate to DMARDS and predicting factors affecting treatment adherence among sample of Egyptian patients with RA.
The aims of the research are: - To predict factors affecting hand dysfunction in patient with rheumatoid arthritis - To study the effect of hand dysfunction on quality of life in patient with rheumatoid arthritis
Rheumatoid arthritis (RA) is a chronic systemic disease affecting primarily the synovium, leading to joint damage and bone destruction(Gravallese E,2002). It is probably the most common autoimmune disease, It is three times more common in women compared to men and usually appears in middle age(poulsom and charles, 2016) .Early diagnosis of RA and its early treatment with disease-modifying anti rheumatic drugs lead to better control and less joint damage .therefore,It is very important to find an acceptable serological marker in order to make an early diagnosis and initiate early treatment to avoid complication and disability ( Orozco C,and Olsen,2006) Various serum biomarkers are used to diagnose RA, including many autoantibodies. However, only rheumatoid factor (RF) and anticyclic citrullinated peptide (anti-CCP) antibodies have wide acceptance (taylor et 2011).
Anxiety and depression are highly prevalent in people with rheumatoid arthritis (RA).This study is to investigate the effect of anxiety and depression on treatment response in people with RA using observational longitudinal study design.
