RESUMO
BACKGROUND: Severe hypertriglyceridemia with an accumulation of chylomicrons and triglyceride figures >1000 mg/dL can cause acute pancreatitis, a potentially fatal complication. The option of rapid reduction in triglyceride concentrations is attractive and possible with plasmapheresis. METHODS: We present the results of an analysis of 11 patients admitted to the intensive care unit with severe hypertriglyceridemic pancreatitis and treated with plasmapheresis. The procedure was repeated until serum triglycerides were below 1000 mg/dL. We recorded anthropometric, clinical data as well as final outcome. RESULTS: In eight patients a single plasma exchange was sufficient to reduce triglyceride figures <1000 mg/dL. Only three patients died, all with the worst severity indexes and who experienced the longest delay before the procedure. CONCLUSIONS: Our results, together with a review of the literature, confirm the need for a randomized clinical trial to compare conventional treatment vs. plasmapheresis in patients with severe hypertriglyceridemic pancreatitis.
