Hepatic encephalopathy in a child: case reportA 9-year-old girl developed hepatic encephalopathy during
treatment with carbamazepine 500 mg/day for tonic-clonicseizures secondary to severe perinatal asphyxia.
After 5 months’ treatment with carbamazepine, the girl wasadmitted to hospital with persistent vomiting, fever, headache,jaundice and elevated serum liver enzyme levels. Thefollowing day she had a headache and hyperemesis and begantreatment for hepatic encephalopathy with an enema andneomycin. Over the next 4 days, she exhibitedhypoprothrombinaemia, elevated serum ammonia levels,asterixis and lethargy. Histological examination of a liverbiopsy showed hepatocyte necrosis with inflammatoryinfiltration of mononuclear and polymorphonuclear cells.
Carbamazepine was stopped. After treatment withprednisone, the girl’s prothrombin levels began to increaseand her bilirubin levels decreased. Prednisone was taperedand discontinued after approximately 2 months. One yearlater, the girl had no evidence of liver damage.
Author comment: ‘Carbamazepine-induced hepatitis is welldocumented in the literature. Suspicion of a drug-relatedetiology in this patient grew only after many days, probablybecause it is not commonly seen in children.’Morales-Diaz M, et al.
