Acute liver failure following therapeutic paracetamol administration in patients with muscular dystrophies
2007
Summary
Clinically significant liver damage in patients taking therapeutic doses of paracetamol is very rare. We report two cases of fulminant hepatic failure caused by therapeutic (4 g.day−1) paracetamol administration on our Intensive Care Unit. Both patients had a muscular dystrophy and presented with a chest infection on a background of endstage neuromuscular respiratory failure. We also noted one further similar case in the literature and suggest a relationship between muscular dystrophy and paracetamol-induced hepatotoxicity. In this report we discuss in detail possible mechanisms that may account for this apparent association, which include altered pharmacokinetics, reduced glutathione stores, malnutrition and hypoxic injury.
