Management of severe hypertriglyceridemia in the hospital: a review

For hospitalists, hypertriglyceridemia (HTG) is more than cardiovascular risk. Severe HTG occurs when serum triglycerides rise above 1000 mg/dL, and it carries a risk of abdominal pain and pancreatitis. The etiology of severe HTG is usually a combination of genetic and secondary factors. A detailed history with attention to family history, medications, and alcohol consumption can often lead to the cause. Physical examination findings may stretch across multiple organ systems. Patients with severe HTG should be admitted to the hospital for aggressive medical therapy if they develop symptoms such as abdominal pain or pancreatitis. Asymptomatic patients with severe HTG who have significant short-term risk for developing symptoms require urgent consultation that may lead to a brief hospitalization to address exacerbating factors. Treatment of severe HTG includes a combination of pharmacologic agents and a restriction on dietary triglyceride intake. If oral medications fail to adequately lower triglyceride levels, intravenous insulin and in rare cases therapeutic plasma exchange may be required. To prevent recurrent severe HTG, the patient should be counseled about adherence to long-term medications and lifestyle changes.
