Rapid Reduction of Severely Elevated Serum Triglycerides with Insulin Infusion, Gemfibrozil and Niacin

Abstract

The conventional methods of treatment of severe hypertriglyceridemia (HTG) are dietatry restriction and lipid lowering medications, mainly fibric acid derivatives. In the medical literature use of insulin infusion to treat HTG has not been highlighted sufficiently. We report a 53-year-old male presented with a four day history of epigastric pain. The patient’s clinical history was significant for hypertriglyceridemia, type-2 diabetes mellitus with medication noncompliance, obesity, status post gastric bypass surgery, alcohol abuse with prior admissions for detoxification. Physical examination revealed mild epigastric tenderness. Laboratory studies revealed severely elevated serum triglyceride (TG) level (8116 mg/dL). Computed tomography (CT) scan of the abdomen exhibited no evidence of pancreatitis. Regular insulin infusion was started at 3 units/hour and gradually increased to 7–10 units/hour. Dextrose infusion was titrated to avoid hypoglycemia and maintain blood glucose levels below 150 mg/dL. Gemfibrozil and niacin were also started. After 24 hours, his TG levels were decreased to 2501 mg/dL. Insulin infusion was continued for about 48 hours. A low carbohydrate diet excluding simple carbohydrates was given. The patient’s serum TG levels normalized over a period of one month. Thus insulin infusion can be considered a safe modality of treatment for rapid reduction of serum TG in addition to fibrates and niacin.
