An oral gold formulation in rheumatoid arthritis. A 12-month follow-up report.

Oral gold(Auranofin; SKF) 6 mg/d has been used in an open study in 31 patients with active rheumatoid disease, 19 of whom have been on continuous treatment for 1 year. Four of these patients were considered to be in remission and 9 had a good clinical response to treatment. Four showed only minimal improvement and 2 did not improve at all. There were, however, no changes in the biochemical parameters of inflammation, e.g. haemoglobin concentration, erythrocyte sedimentation rate, platelet count and rheumatoid factor, or in renal and hepatic function. Of the 31 patients, 9 (29%) have discontinued treatment but only 3 (9.7%) because of side-effects. Minor side-effects have been fairly common, occurring in 19 patients (61%), and included skin rashes and pruritus, diarrhoea and loose stools, nausea, stomatitis and thrombocytopenia or leucopenia. Oral gold would seem to be a safer, less potent form of chrysotherapy than parenteral gold.
