Impact of Hypertriglyceridemia on the Outcome of Acute Biliary Pancreatitis

Abstract

BackgroundHypertriglyceridemia (HTG) is a well-recognized cause of acute pancreatitis (AP). However, the role of HTG in modulating disease course remains to be cleared. We aimed to explore the impact of HTG on the outcome of acute biliary pancreatitis (ABP). MethodsA total of 90 ABP patients with HTG were enrolled in this study and were divided into 3 groups based on ABP severity: mild AP, moderately severe AP (MsAP) and severe AP (sAP), according to the modified Atlanta classification. Besides, patients were divided into type I, II and III HTG groups based on the triglyceride (TG) level, according to the national cholesterol education program (NCEP). Disease severity, Ranson score and complications were recorded and analyzed. Logistic regression analysis was performed to screen predictive risk factors of severe outcomes. ResultsThere were 23 patients with SAP, 41 with MSAP and 26 with mild AP among the ABP patients with HTG. Significant differences were observed in the obesity, plasma TG level and Ranson score among groups. The risk of developing MSAP in ABP patients with type II and III HTG was increased. Similarly, the risk of developing SAP in ABP patients with type III HTG was also enhanced. The incidence of systemic, especially respiratory failure, and local complications in type III HTG group were significantly higher than normal lipid group. ConclusionsHigh TG level (≥2.26mmol/L or 200.11mg/mL) may be a risk factor for severe ABP and the development of systemic and local complications in ABP.
