Of Interest on Rheumatoid Arthritis from
Rheumatoid arthritis (RA) is an autoimmune disease that can cause chronic inflammation of the joints and other areas of the body. Rheumatoid arthritis can affect persons of all ages. Its cause is unknown. Rheumatoid arthritis is a chronic disease that is characterized by periods of disease flares and remissions. In RA, multiple joints are usually, but not always, affected in a symmetrical pattern (affecting both sides of the body). The chronic inflammation of RA can cause permanent joint destruction and deformity. The "rheumatoid factor" is an antibody blood test that can be found in 80 percent of patients with RA.
Rheumatoid arthritis is a common rheumatic disease, affecting more than two million people in the United States. The disease is three times more common in women than in men. It afflicts people of all races equally. The disease can begin at any age, but most often starts after age forty and before sixty. In some families, multiple members can be affected, suggesting a genetic basis for the disorder.
