title: Dramatic improvement of psoriatic erythroderma after acute hepatitis: analysis of cytokine synthesis capability in peripheral blood T cells.
abstract: We report a patient with psoriasis and hepatitis C virus infection who initially presented with psoriatic erythroderma and eventually showed complete clearance of psoriatic lesions following acute hepatitis induced by etretinate treatment. Cytokine synthesis capabilities in peripheral blood T cells obtained at different stages were evaluated in this patient. A dramatic increase in the frequency of interferon-gamma-producing CD8+ T cells in peripheral blood was observed during the erythrodermic stage. In contrast, the frequencies of interleukin (IL)-4- and IL-13-producing CD4+ T and CD8+ T cells were remarkably high at the resolution stage. These results clearly indicate that a shift towards type 2 cytokine predominance contributes to the resolution of severe psoriasis.
