Acute pancreatitis in HIV-infected patients with or without AIDS has been reported with increasing frequency over the past several years. Drugs used to treat HIV-infected patients are often the cause. We report a case of a 46-year-old HIV-infected man who presented to the emergency department with abdominal pain and was diagnosed with acute pancreatitis. The patient had recently begun taking 2',3'-dideoxyinosine (ddI). He died shortly after admission to the hospital; CT scan and autopsy confirmed the cause of death as hemorrhagic pancreatitis. We briefly review the literature on the incidence and severity of pancreatitis in association with ddI and pentamidine therapy.
