Clinical features and outcomes of hypertriglyceridemia-induced acute pancreatitis: Propensity score matching analysis from a prospective acute pancreatitis registry

초록

Background: Hypertriglyceridemia (HTG) is a well-known cause of acute pancreatitis (AP) and elevation of serum triglycerides (TG) to ≥1000 mg/dl is strongly indicative of HTG-induced AP (HTG-AP). HTG-AP is potentially associated with persistent organ failure and poor prognosis. Here, we compared differences in clinical features and outcomes between patients with HTG-AP and patients with AP due to other causes. Methods: A prospective AP registry was constructed in Gil Medical Center between June 2014 and May 2018. In total, 499 patients with AP were included for whom serum TG data at admission were available. Results: HTG-AP was present in 52 patients (10.4%); these patients were younger than patients with AP due to other causes (39.62 ± 10.12 vs. 51.62 ± 17.41, p < 0.001). After propensity score matching adjusted by age, the factors associated with severity were more common in the HTG-AP group; these factors included the presence of systemic inflammatory response syndrome, Ranson's score ≥3, acute physiology, age, chronic health evaluation (APACHE) II score ≥8 at admission, and C-reactive protein level >10 mg/dl after 24 h of hospitalization. There were no significant differences in complications or severity based on the revised Atlanta classification 2012. In addition, recurrence was more frequent in the HTG-AP group (25.0% vs. 6.4%, p < 0.001). Conclusion: HTG-AP occurred in younger patients and showed more frequent recurrences than AP with other causes. Although factors related to severe feature were more common in HTG-AP during early phase, overall severity and prognosis were not different between the two groups. © 2020
