Effect of plasmapheresis versus standard treatment in preventing recurrent acute pancreatitis in Chinese patients with hypertriglyceridemia.

The present study designed to compare the effect of plasmapheresis (PPH) versus standard treatment (STD) in preventing recurrent AP in Chinese patients with severe hypertriglyceridemia. Chinese patients aged 18 to 65 years who had history of hypertriglyceridemia (>1000mg/dl) induced acute pancreatitis were assigned to plasmapheresis (up to 1.5 ml daily TG level reaches 500 mg/dl or less) or standard treatment (1:1). Standard treatment (STD) includes limited oral intake (pancreatic rest), intravenous hydration and pain management. Primary endpoint was incidence of recurrent acute pancreatitis. A total of 14% of patients in PPH group (N=50) had experienced recurrent pancreatitis as compared to 24% of patients in STD group (N=50). Also, TG clearance rate in 24 hours was substantially higher in PPH group as compared to STD. Time required to reach target TG was significantly lower in patients treated with PPH as compared to STD. Lower incidence of local complications was observed in PPH group as compared to STD. Length of stay was significantly shorter in patients of plasmapheresis group as compared to standard treatment. The results of this study recommend the use of plasmapheresis as a better alternative in preventing recurrent AP in Chinese patients with severe hypertriglyceridemia.
