[A case of overlap syndrome of PSS, SLE and Sjögren syndrome treated by cyclosporin A: an improvement of sclerosis of the skin].

A 26-year-old female patient complicated with PSS, SLE and Sjögren was treated by combination of medium doses of corticosteroid and cyclosporin A. On admission, she showed many abnormal laboratory findings such as increased serum gammaglobulin level, high anti-DNA antibody titer and low compliment level. This therapy improved not only these laboratory abnormalities but clinical symptoms including sclerosis of the skin and arthritis, without notable side effect due to either of these drugs for the following 10 months so far. On the other hand we haven't acknowledged the effect to internal involvement yet. Since there is no promising therapy to sclerosis of the PSS skin, it is suggested that cyclosporin A can be an effective agent for PSS and should be further evaluated.
