Abstract: | Thirty patients (22 women) with active rheumatoid arthritisparticipated in an open study of 6 months' treatment with eitherenteric-coated sulphasalazine (SASP) or SASP plus D-penicillamine(DPA). Patients were assessed at regular intervals using a numberof clinical and biochemical tests designed to detect specificantirheumatic activity. There were significant improvements in clinical and laboratoryvariables with both regimens consistent with second-line activity.Improvements were greater and more numerous with combinationtherapy. At the end of the trial period, there were nine respondersin the SASP/DPA group but only six in the SASP group. Neitherefficacy nor toxicity could be related to patient acetylatorstatus. Nausea and dyspepsia were frequent problems with both treatmentregimens but dysgeusia and thrombocytopenia were confined tothe SASP/DPA group. Study withdrawals were twice as common withcombination therapy. These results suggest that a combination of SASP and DPA ismore potent than SASP alone but at the expense of poorer patienttolerance.
