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.
