Rheumatoid Arthritis

Rheumatoid arthritis (RA) is a chronic systemic inflammatory autoimmune disease. It is characterized typically by a symmetric polyarthritis that can be destructive and disabling, and in some occasions, extra-articular manifestations, making RA a heterogeneous disease. The diagnosis is based on clinical assessment and can be supported by serological markers and imaging. Early diagnosis and treatment of RA can slow the disease progression and prevent disability. New drugs and treatment strategies have improved disease outcomes.
