Cyclosporin A (CyA) is a very effective immunosuppressor for inhibition of the humoral immune response and especially for cell mediation and was originally indicated for transplantation of organs and autoimmune diseases. More recently, CyA has been used successfully for severe psoriasis. In this study, the authors describe the results obtained from 8 patients who presented with a psoriatic arthropathy, treated with small doses of CyA (3-5 mg/kg/day). There were reactions in five of them, in two patients the Ritchie index decreased moderately and in one patient the arthritic psoriasis was significantly improved.
