[Laboratory and oligobiopsy studies of the liver in patients with psoriasis treated by the combination of Tigason-PUVA-cignoline (RePUVA+C)].

In 10 patients with generalized psoriasis treated by this method biochemical and histological examinations of liver biopsy specimens were done before and after 60 days of the treatment. In some cases a transient rise of A1AT activity, raised activity of alkaline phosphatase and gamma-glutamyltranspeptidase were noted. Histological examinations demonstrated slight hepatocellular damage with microfocal necrosis, fatty infiltration of some cells and increase in the structural elements of cytoplasm.
