title: Epidemiology, pathophysiology, and diagnosis of rheumatoid arthritis: A Synopsis.
abstract: Rheumatoid arthritis (RA) is one of the more common autoimmune disorders, affecting approximately 1% of the population worldwide. The exact cause of RA is not known; however, initiation of disease seems to result from an interaction among genetic susceptibility, environmental triggers, and chance. RA is characterized by dysregulated inflammatory processes in the synovium of the joint that eventually leads to the destruction of both cartilaginous and bony elements of the joint, with resulting pain and disability. Systemic inflammation associated with RA is associated with a variety of extra-articular comorbidities, including cardiovascular disease, resulting in increased mortality in patients with RA. RA is also associated with several psychosocial disorders. Classification criteria for RA that were promulgated jointly by the American College of Rheumatology and the European League Against Rheumatism in 2010 emphasize early detection of RA so that effective management can be initiated before pathological changes become irreversible.
