[Risk of acute hepatic insufficiency in children due to chronic accidental overdose of paracetamol (acetaminophen)]

Abstract

Two girls aged 4 and 3 years, respectively, experienced acute liver failure due to accidental ingestion of supratherapeutic doses of paracetamol (90 mg/kg/day or more). Recognition of chronic paracetamol intoxication as a cause of acute hepatic failure is often delayed. It is important to consider the possibility of paracetamol-induced hepatotoxicity because many patients will recover if treated with N-acetylcysteine, as did both of these children. Patients with acute liver failure due to chronic paracetamol intoxication present with very high transaminase levels (> 4000 U/l), disproportionately low total bilirubin levels (< 200 micromol/l) and often hypoglycaemia.
