Combination therapy with hydroxychloroquine, gold sodium thiomalate and methotrexate in early rheumatoid arthritis. An open 3-year study.

During recent years, aggressive therapeutic approaches have been proposed in order to control the Rheumatoid Arthritis (RA) activity and to avoid joint destruction. Here we report the results of an open 3-year trial on the combination of three second-line drugs, hydroxychloroquine (HCQ), methotrexate (MTX) and gold sodium thiomalate (GST), in early active RA. Four men and 17 women were enrolled in the study and were treated during the first year with HCQ 400 mg/day, GST 50 mg/week and oral MTX 7.5 mg/week; during the second and the third years the doses of HCQ and MTX were reduced to 200 mg/day and 5 mg/week, respectively; the interval between the GST injections was progressively increased until 4 weeks. Prednisone at an initial dose not higher than 10 mg/day was associated. Sulindac was allowed. Eight patients left the study because of side-effects, 2 patients abandoned the study, 12 patients compleated the 3 years of treatment. We obtained a significant and early amelioration of both clinical and laboratory parameters during the first year; in the two subsequent years the positive results were maintained. In our opinion the most significant result is the absence of anatomical progression in 10 out of 12 patients, even if a more prolonged observation is necessary to obtain more reliable data.
