Glucagon-like peptide-1 receptor agonist liraglutide is widely used in type 2 diabetes mellitus and obesity and is generally considered non-hepatotoxic, with only rare reports of idiosyncratic liver injury. We report the case of a 58-year-old obese woman with type 2 diabetes who developed marked hepatocellular injury 12 weeks after initiating liraglutide therapy, with alanine aminotransferase (ALT) 876 U/L and aspartate aminotransferase (AST) 702 U/L after exclusion of alternative causes. Liver enzyme levels improved rapidly following drug discontinuation. A supervised rechallenge resulted in recurrence of severe transaminitis (ALT 1245 U/L, AST 980 U/L) within 10 days, with RUCAM score of 11 supporting a highly probable drug-induced liver injury. This case highlights a rare but definite idiosyncratic hepatocellular injury associated with liraglutide. Prompt recognition, discontinuation, and avoidance of rechallenge are essential. Further pharmacovigilance is warranted to better characterize incidence and mechanisms and guide safe clinical use of GLP-1 therapies in practice settings.

Diseases of the Liver and Gallbladder
Cirrhosis is characterized by the scarring of hepatic lobules in the liver, which are replaced by fibrous tissue, affecting the liver's normal functioning. NAFLD, on the other hand, is caused by an excessive build-up of fat in the liver, not related to...

Acute Pancreatitis I: Introduction
Acute pancreatitis is characterized by rapid inflammation of the pancreas, often caused by factors like gallstone blockage or excessive alcohol consumption. Chronic pancreatitis, on the other hand, is a slow, progressive inflammation that may result from long-term alcohol abuse, obstructions in the pancreatic duct, or genetic factors.
