Prior gold therapy does not influence the adverse effects of D-penicillamine in rheumatoid arthritis

Abstract

One hundred fourteen patients with definite or classic rheumatoid arthritis were followed prospectively between January 1976 and April 1981 to monitor their toxicity pattern to D-penicillamine. The influence of previous sodium aurothiomalate therapy on the toxicity pattern of D-penicillamine is described. There was no significant difference in overall outcome of the patients treated with D-penicillamine with respect to adverse effects, whether they had previous gold toxicity, previous gold therapy but no toxicity, or no previous gold therapy. The time from gold toxicity to the start of D-penicillamine therapy was greater in those who did not develop D-penicillamine toxicity compared with those who did. This difference just reached statistical significance. Total gold salt received had no effect on eventual outcome of D-penicillamine treatment, and the toxicity pattern of D-penicillamine in those patients who had previous gold therapy was similar to those patients who had never received gold therapy.
