Abstract
Case details: A 19-year-old girl presented to the emergency department following overdose of 10 g of paracetamol on a background history of cystic fibrosis. Paracetamol concentration was below the nomogram line, but was treated with acetylcysteine seven hours post-overdose given her symptomatology. Nineteen hours following her overdose she developed hepatotoxicity, despite early initiation of acetylcysteine. She was discharged well six days post-ingestion. On presentation, delta miRNA-122-miR483 was 20 times that of control patients, however, alanine aminotransferase was normal. Discussion: Patients with cystic fibrosis are more likely to have glutathione deficiency, and greater susceptibility to liver injury. Delta miRNA may be a better detector of early liver injury than hepatic aminotransferases. Empiric treatment with acetylcysteine and serial biochemical reassessment in this setting should be considered.
