Background The therapeutic effect of plasma exchange (PE) on hypertriglyceridemic acute pancreatitis (HTGAP) is unclear. Therefore, we aimed to explore this therapeutic effect. Study design and methods This study included 204 patients with HTGAP who underwent treatment at two provincial tertiary grade A hospitals in Fujian Province from October 2012 to May 2021. Patients were divided into a conventional group and a PE group. The Student's t‐test and chi‐square test were used for data analysis. Results Among 204 patients, 56 and 148 were included in the PE and conventional groups, respectively. After propensity score matching (PSM), the PE and conventional groups each had 42 patients. There was no significant difference in age; sex; pregnancy; comorbidities; laboratory findings; incidences of complications, and multiple organ dysfunction syndrome (MODS); organ support treatment; surgical rate; mortality; and hospital stay between the groups (p > 0.05). The total expenses were significantly higher in the PE group than in the conventional group (p < 0.05). There was no statistically significant difference in the times of PE; total volume of PE; incidences of complications, and MODS; organ support treatment; surgical rate; mortality; and hospital stay between the early PE and delayed PE groups (p > 0.05). All patients in the PE group and conventional group with acute renal failure had significantly higher D‐dimer levels than those without acute renal failure (p < 0.05). Discussion Compared with conventional treatment, PE does not have a better therapeutic effect on HTGAP. The D‐dimer level can predict whether patients with HTGAP will have acute renal failure.

Background The effect of hepatitis B virus (HBV) replication during pregnancy on the outcomes of singleton pregnancies is not fully understood. In this study, we investigated the association between HBV replication and poor maternal and infant outcomes. Methods We retrospectively analyzed the clinical data of 836 pregnant inpatients with hepatitis B surface antigen positivity who delivered at two provincial tertiary grade A hospitals in Fujian Province from June 2016 to October 2020. The patients were divided into the HBV replication (n = 283) and non-HBV replication groups (n = 553). Chi-squared test of adverse maternal and infant outcomes was performed using SPSS 26.0 software, and univariate analysis of variance of basic clinical indexes of pregnant women and newborns was performed. P<0.05 was considered statistically significant. Results The incidences of perinatal outcomes of intrahepatic cholestasis of pregnancy, hypertensive syndrome complicating pregnancy, gestational diabetes mellitus, preterm birth, macrosomia, growth restriction, and vaginal infection in the HBV and non-HBV replication groups were not significantly different (P>0.05); however, there were significant differences between the two groups in the rate of cesarean section (53.8% vs. 45.0%; P=0.017) and neonatal jaundice (15.5% vs. 7.2%; P=0.000). After using propensity score analysis and multivariable modeling to adjust for glutamic pyruvic transaminase and glutamic oxaloacetic transaminase levels in the two groups, the replication group was found to have an increased risk for cesarean section (54.3% vs. 33.5%; P=0.000) and vaginal infection (3% vs. 0.4%; P=0.038), and their infants had a higher rate of newborn jaundice (16% vs.1.5%; P=0.000). Conclusion The findings provide further understanding of the association between maternal HBV replication status and perinatal outcomes. Pregnant women with viral replication have an increased risk of vaginal infection and cesarean section, and their infants appear to be at a higher risk for neonatal jaundice.
