[Success of cyclosporine therapy in two patients with PSS]

Two PSS patients, unresponsive to D-penicillamine, steroid, cyclophosphamide and plasma exchange therapy, were treated with cyclosporine. One patient complained scleroderma, dysphagia and dyspnea during movement after treatment with steroid, plasma exchange and cyclophosphamide. He showed a increased Leu3a/2a ratio (6.72). About 3 months after treatment with cyclosporine, these complain decreased with normalization of elevated Leu 3 a/2 a ratio. 1 year after treatment, %DLco increased 86% from 50% and pneumonitis findings of chest X-ray and chest CT were also improved. Another patient who complained Raynaud's phenomenon and scleroderma which had extended over his abdomen despite treatment with steroid and cyclophosphamide. 1 month after treatment with cyclosporine, improvement of these phenomenon were recognized. It is concluded that cyclosporine can be an effective agent in the treatment of PSS.
