Disulfiram-induced Hepatitis: Case Report and Review of the Literature

A case of hepatitis is reported in a 38-year-old alcoholic woman taking disulfiram to aid in maintaining sobriety. She presented with anorexia, vomiting, fatigue, right upper-quadrant pain, pruritus, darkened urine, and jaundice after about two weeks of disulfiram 500 mg/d. The patient also had been taking enalapril 10 mg/d for one year. Hepatocellular enzymes, total bilirubin, and eosinophils were significantly elevated. Hepatitis B core antibody, hepatitis A antibody, hepatitis B surface antibody, and antinuclear antibody were negative. After discontinuation of disulfiram, the clinical and biochemical manifestations of hepatitis began to resolve and the patient was discharged in a much improved condition. Seventeen previous cases of disulfiram-induced hepatitis are reviewed. It has been suggested that the mechanism of hepatotoxicity is an allergic or hypersensitivity reaction. The findings in this case are consistent with the earlier descriptions of hypersensitivity hepatitis, and lend further support to the possibility that disulfiram may cause hepatitis.
