Drug-Induced Liver Disease: Clinical Course.

Drug-induced liver injury (DILI) is a term used to describe a spectrum of clinical presentations and severity that ranges from mild elevation of liver enzymes on routine blood work to acute liver failure and death. Approximately 10% of all patients with DILI develop acute liver failure resulting in death or liver transplantation. DILI may be prolonged with persistence of elevated liver enzymes for longer than 6 months in approximately 5% to 20% of cases. Cirrhosis and long-term liver-related morbidity and mortality have also been described but are rare, occurring in 1% to 3% of cases.
