Abstract
A few cases of alcohol-like chronic liver disease have recently been described in patients on high daily doses of amiodarone (400-600 mg) for 5-24 months. We report here 3 cases in which similar lesions were observed after low daily doses of amiodarone. Daily dosage was 200 mg in 2 cases, 400 mg then 200 mg in the third one, and duration of therapy ranged between 36 and 60 months. Symptomatology was limited to hepatomegaly and/or mild elevation of serum aminotransferases. Liver biopsy showed alcohol-like lesions with fibrosis in 2 cases and cirrhosis in 1 case. Electron microscopy disclosed hepatic phospholipidosis. These cases indicate that chronic liver disease may be observed even when amiodarone is prescribed at low daily dosage, provided that duration of treatment is long. They also suggest that rather than the daily dosage, the cumulative dose of amiodarone is a major factor in the development of hepatic injury.
