Clinical features and treatment of hypertriglyceridemia‐induced acute pancreatitis during pregnancy: A retrospective study

Aim : To analyze the features and treatment of hypertriglyceridemia‐induced acute pancreatitis (HTGP) during pregnancy. Methods : A retrospective study of 21 pregnant women diagnosed with acute pancreatitis (AP) was performed. Patients were divided into acute biliary pancreatitis (ABP), HTGP, and idiopathic groups according to etiology. Results : 95% of the patients were in the third trimester of gestation. The percentage of patients with HTGP was higher than that of ABP (48% vs.14%). The percentage of severe acute pancreatitis (SAP) in the HTGP group was higher than that in the ABP group (40.0% vs.0%). The Ranson scores for moderately severe acute pancreatitis (MSAP) and SAP in the HTGP group were significantly different (2.50 ± 0.58 vs.3.60 ± 0.89, P  < 0.05, respectively). The mean serum triglyceride (TG) levels in the MSAP and SAP HTGP groups were not significantly different (18.81 ± 11.13 vs. 30.53 ± 24.20 mmol/L, P  > 0.05, respectively). In the HTGP group, there were five patients given plasma exchange therapy and five not. Plasmapheresis decreased the incidence of systemic inflammatory response syndrome (SIRS) from 100% to 28.6% and the TG level from 20.36 ± 7.41 mmol/L to 5.23 ± 3.62 mmol/L ( P  < 0.05). The length of hospitalization of the plasmapheresis group was shorter than that of the nonplasmapheresis group (17.3 ± 6.7 days vs. 37.0 ± 20.8 days). Conclusions : Plasma exchange may be safe and effectively administered for HTGP patients during pregnancy with SIRS or multiple organ dysfunction syndrome (MODS). J. Clin.
