Rheumatoid arthritis

Rheumatoid arthritis (RA) is an autoimmune disease that is based on synovitis and may eventually lead to joint deformities. Its etiology is still being explored, but studies suggest that it may be closely related to autoimmunity, genetics, and microbial infections. Clinical manifestations are mainly joint lesions, with morning stiffness, swelling and pain in the joints, which may develop into joint deformities as the disease progresses, affecting the normal joint function of the patient. Some patients may also show systemic symptoms, such as fever, fatigue and weakness.
