Initiation time of double-filtration plasma apheresis affects the risk of persistent organ failure in hypertriglyceridaemia-induced acute pancreatitis: a retrospective study
Scientific reports(2023)
Abstract
The effect of double filtration plasma apheresis (DFPP) on improving the outcomes of patients with hypertriglyceridaemia-induced acute pancreatitis (HTG-AP) remains unclear. The aim of this study was to evaluate the relationship between the initiation time of DFPP and the risk of persistent organ failure (POF) in an HTG-AP cohort in China. We retrospectively evaluated data from HTG-AP patients treated with DFPP 48 h after diagnosis between January 2017 and January 2022. Comparisons across tertiles of the interval from diagnosis to completion of one DFPP session (DTD) were analysed. Logistic regression models and restricted cubic splines (RCS) were used to determine the correlation between the DTD time and risk of POF. Of the 89 patients enrolled, 46 patients (51.69%) suffered POF in the first week of HTG-AP. DFPP was initiated at a median of 17 h after the diagnosis was confirmed. The patients in the highest tertile of DTD time had a significantly increased prevalence of POF. After multivariate adjustment, the logistic regression models found a significant decrease in the odds ratios (OR) of POF from the highest to the lowest DTD tertile (P for trend = 0.006). Moreover, the RCS curves showed a nonlinear relationship in the adjusted OR of POF and DTD time, which remained relatively low and flat during the early DTD time but increased sharply afterwards. Early initiation of DFPP treatment correlates with a reduced risk of POF in HTG-AP patients.
