Acute pancreatitis due to hypertriglyceridemia: Plasmapheresis versus medical treatment.

Objective: Hypertriglyceridemia (HTG) is the third-most common cause of acute pancreatitis. Plasmapheresis is an extracorporeal treatment method used for treatment. This study aimed to investigate the efficacy of medical treatment and plasmapheresis in patients with acute pancreatitis due to HTG.

Methods: This was a retrospective cross-sectional study. The patients were divided into two groups according to the treatment they received as those who received only medical treatment and those who performed plasmapheresis with medical treatment. According to the treatment received by the patients; clinical, demographic, and laboratory data, Ranson scores, and bedside index of severity in acute pancreatitis (BISAP) scores, decrease in triglyceride levels in 24 h, length of hospital stay, and outcomes were recorded.

Results: Forty-seven patients were included in the study. The level of triglyceride decreases at the 24^th h was 59.7% ±17.3% in those who received medical treatment and was 70.4% ±15.1% in those who received plasmapheresis (P = 0.032). Receiver operating characteristic curve analysis was performed to predict the need for plasmapheresis treatment, area under the curve (AUC) value of the triglyceride level was the highest (AUC: 0.822, 95% confidence interval: [0.703-0.940]; P < 0.001), the sensitivity and specificity were 83.3% and 72.4%, respectively, and the cut-off value of triglyceride was accepted as 3079.5 mg/dL.

Conclusion: Plasma triglyceride levels and BISAP score on admission may help physicians to predict the need for plasmapheresis. Plasmapheresis helps to rapidly reduce triglyceride levels in patients with HTG-associated acute pancreatitis.
