[Ulcerative colitis caused by oral gold therapy in rheumatoid arthritis]. / Ulzerierende Kolitis unter oraler Goldtherapie bei rheumatoider Arthritis.

ABSTRACT

We report on a 39-year-old male patient suffering from seropositive rheumatoid arthritis who developed severe colitis during oral gold (Auranofin) therapy. So far, two further cases of colitis during oral, and 28 cases of enterocolitis during parenteral chrysotherapy have been described. The pathomechanism has not been identified. Symptomatic therapy was applied, under which our patient recovered from intestinal discomfort in a few weeks. In differential diagnosis gold induced colitis has to be distinguished both from loose stools occurring during oral gold therapy, most probably caused by an inhibition of NA+K+ ATPase, and from colitis induced by concomitant application of nonsteroidal anti-inflammatory drugs.
