Abstract

Patients with rheumatoid arthritis (RA), 500 men and 500 women, aged 40 years and over, together with a control population matched by age and sex, were observed over a 10 year period. The overall mortality was significantly higher in both men and women with rheumatoid arthritis than in the controls due to an excess mortality from infections and cardiovascular and renal diseases. During the follow up 31 patients with RA (12 male, 19 female) and one male control subject died from amyloidosis and 42 RA patients (19 male, 23 female) and one male control from renal diseases. The most important causes of renal deaths were chronic nephritis and renal infections.
