title: A study of potential hepatotoxicity of etretinate used in the treatment of psoriasis.
abstract: Etretinate was used to treat twenty patients who had severe, disabling psoriasis and an increased risk of liver damage. Potential hepatotoxicity was evaluated by obtaining liver biopsies prior to starting therapy and after a 6-month course on a dosage of 0.75 mg/kg/day. In comparing pretreatment biopsies to posttreatment biopsies, five of twenty patients demonstrated a morphologic change in their liver. Three showed progressive fatty metamorphosis, and two showed liver cell necrosis and progressive fibrosis. One of these was due to heavy alcohol intake. Based on our 6-month evaluation, etretinate does not produce a consistent toxic effect on the liver.
