Infection in rheumatoid arthritis.
Sepsis is an unusually common cause of illness and death in RA. All sorts of infections occur, but pyarthrosis produces exceptional problems. Clinically, pyarthrosis, empyema, and purulent pericarditis mimic bland rheumatoid effusions. Aspiration of the attendant effusions is the only reliable diagnostic procedure. Subcutaneous nodules on the sacrum and back are easily overlooked. Necrosis and ulceration of these nodules may provoke septicemia. Those with Felty's syndrome do not uniformly have problems with recurrent infection. Splenectomy may not benefit such patients. The belief that corticosteroids cause increased infections in rheumatoid patients is not totally justifiable at present. Steroids can, however, disguise underlying sepsis and hamper proper diagnosis.
