Lisinopril-Induced Acute Necrotizing Pancreatitis

Lisinopril is an angiotensin-converting enzyme (ACE) inhibitor that is used as one of the first-line antihypertensive medications. Necrotizing pancreatitis induced by the use of ACE inhibitors is an extremely rare occurrence. Although an uncommon risk factor, our aim is to further highlight that patients with chronic use of lisinopril can develop such complications and should be considered among the list of differential diagnoses for pancreatitis. A 53-year-old Caucasian male with a history of hypertension treated with lisinopril presented with a one-day history of nausea, vomiting, and severe epigastric pain. On physical examination, there was tenderness to palpation in the epigastric region and left lower quadrant without rebound tenderness or guarding. A complete blood count showed a slight increase in white blood cell count to 12,000 cells/mm(3) and serum lipase level was elevated at 1028 U/L. A subsequent CT scan of the abdomen with contrast revealed findings supporting necrotizing pancreatitis. The patient was treated with conservative medical management with goal-directed intravenous fluid support, early enteral feeding, and pain control. His condition resolved, and he was found doing well on follow-up visits.
