Abstract
Severe hypertriglyceridemia (serum triglyceride >10mmolL-1 ) is implicated in ~9% of acute pancreatitis cases. Certain guidelines list severe hypertriglyceridemia as an indication for plasmapheresis. We assembled the natural trajectory of triglyceride levels in patients with acute pancreatitis due to severe hypertriglyceridemia who were managed conservatively without plasmapheresis to evaluate the effectiveness of this approach. A retrospective chart review was performed on 22 hospital admissions for acute pancreatitis episodes considered to be caused by severe hypertriglyceridemia. Patients were managed supportively, with cessation of oral intake (NPO) and intravenous hydration. Insulin infusion was used in 12 patients to manage concurrent hyperglycaemia. Triglyceride levels for the group were evaluated using a mixed-effects model. The average triglyceride level fell from 45.4mmolL-1 on presentation to 13.3mmolL-1 within 48h, corresponding to a mean 69.8% decrease. Regression analysis showed a triglyceride half-life of 30.6h. Findings were similar for NPO-only and insulin infusion subgroups. Patients with severe hypertriglyceridemia and acute pancreatitis can be conservatively managed safely and effectively without plasmapheresis.
