Hepatitis induced by drugs used as alcohol aversion therapy.
We report here on the hepatic lesions produced in 17 alcoholic patients who had received Cyanamide or Disulfiram as aversion therapy. The characteristic lesion consists of cytoplasmic inclusions, similar to Lafora bodies. They are found predominantly in periportal hepatocytes, including those lining the cholangioles. They appear to be persistent but are lost after death of the inclusion-bearing liver-cell when both the inclusion body and the dead hepatocyte are removed by macrophages. As well as the inclusion bodies, portal or periportal inflammation and necrosis of isolated liver-cells are seen. The inflammatory infiltrate is usually denser in the periportal areas and is associated with liver-cell destruction. The inflammation is usually followed by portal fibrosis which can be severe if treatment is prolonged. In one case, in which two biopsies were performed, cirrhosis developed while that patient was on Cyanamide.
