Abstract
We surveyed the member institutions of the Japan Psoriasis Association in order to elucidate (1) the subjects of concern for the deeper understanding of the pathogenesis of psoriasis and (2) the current treatment modalities for psoriasis in Japan. The results showed that gene analysis and discovering the immune desorders surrounding cytokines are the two main areas of interest in clarifying its pathogenesis. Current popular treatment modalities are (1) oral cyclosporin and (2) oral etretinate for systemic therapies and (1) topical vitamin D3 application, (2) topical steroid application, and (3) topical PUVA treatment for local treatments. Combination therapies consist of (1) low dose oral etretinate with topical steroid or (2) low dose oral etretinate with topical PUVA treatment. The results of this survey reflect the current general knowledge of the pathogenesis and the treatment of psoriasis.
