Treatment of Hypertriglyceridemia-Induced Acute Pancreatitis With Insulin, Heparin, and Gemfibrozil: A Case Series

Abstract

Hypertriglyceridemia is the third most common worldwide cause of acute pancreatitis. Resolving the underlying etiology is imperative for optimal management. This is especially true with regard to hypertriglyceridemia, as this etiology may cause more severe acute pancreatitis and worse symptoms than other causes of the disease. Many pharmacological treatment options for hypertriglyceridemia-induced acute pancreatitis (HTGP) have been proposed; however, the safety and efficacy for specific treatment regimens remain nebulous. At our institution, 6 patients, whose average Ranson criteria score were 5 and presenting triglyceride concentrations were 3501 mg/dL, were managed with a continuous infusion of insulin, subcutaneous heparin, and oral gemfibrozil for HTGP. Maximum insulin infusion rates ranged from 0.8 to 20.9 U/h. Half of the patients received nongemfibrozil cholesterol medication. Five patients experienced a resolution of HTGP (median day 3). The only adverse drug event was hypoglycemia in a single patient. Combination therapy with heparin, insulin, and gemfibrozil is safe and efficacious in quickly lowering serum triglyceride concentrations in HTGP. This combination warrants further study.
