Vitamin A metabolism involves storage in the liver. Hypervitaminosis A results in liver abnormalities, including fibrosis and cirrhosis. Ito cells are increased and promote fibrogenesis, which results in cirrhosis. Retinoids (Accutane and Tegison) are used clinically for the treatment of a variety of skin diseases. Since retinoids are analogs of vitamin A, their potential to produce liver disease is reviewed. Animal and human studies of liver function tests suggest some abnormalities in the liver in about 25% of patients treated. Liver biopsy studies have included isolated case reports and two retrospective and one prospective liver biopsy study of retinoids in humans. Although some increase in histologic liver changes have been noted, most liver biopsy specimens showed no change or improvement. Retinoids do not appear to produce consistent toxic liver abnormalities.
