Rheumatoid arthritis : | |||||||||||||
A chronic systemic disease that causes inflammatory changes in the synovium, or joint lining, that result in pain, stiffness, swelling, and ultimately loss of function and deformities of the affected joints due to destruction of the cartilage and adjacent bone. The disease can also affect other parts of the body. In the past it was also called chronic polyarthritis. It is more common in women than men, and at least 70% of patients show a positive blood test for rheumatoid factor.
