RA is rheumatoid arthritis. Rheumatoid Arthritis is an autoimmune disease in which the immune system attacks and destroys the joints. Lupus is an autoimmune disease that can affect virtually any part of the body. Lupus does not destroy joints, but it does cause pain and inflammation.

Rheumatoid arthritis does not cause lupus, but it is common to have more than one autoimmune disease in overlap.
