title: Toxicity due to remission inducing drugs in rheumatoid arthritis. Association with HLA-B35 and Cw4 antigens.
abstract: Twenty-five patients with rheumatoid arthritis (RA) who developed toxicity while taking remission inducing drugs and 30 without toxicity were studied for possible associations with class I and II HLA antigens. A strong association has been found between nephritis and dermatitis due to Tiopronin (a D-Penicillamine like compound) and class I antigens B35-Cw4, and between dermatitis due to gold thiosulphate and B35. Compared to healthy controls a lower DR5 frequency was observed in patients with RA except for the Tiopronin related nephritis group.
