Analysis of the effect of double filtration plasmapheresis on hyperlipidemic acute pancreatitis

Objective To evaluate the effect of double filtration plasmapheresis (DFPP) on patients with hyperlipidemic acute pancreatitis (HL-AP). Methods The clinical data of the patients with hyperlipidemic severe acute pancreatitis (HL-SAP) or moderately severe acute pancreatitis (HL-MSAP) from January 2019 to May 2022 were collected. The patients were divided into two groups,the control group received conventional treatment, DFPP group received DFPP treatment on the basis of conventional treatment. Results Compared with the control group, the following parameters changed significantly in DFPP group, triglyceride (TG), alanine aminotransferase (ALT) and aspartate aminotransferase (AST) decreased on day 1 and 2, estimated glomerular filtration rate (eGFR) increased on day 1, 2, 3 and 5, leukocyte and neutrophil counts decreased on day 1 and 2, hemoglobin (HGB) decreased on day 1, 2, and 3, C-reactive protein (CRP) decreased on day 1, 2, 3, 5, and 7. And the patients in DFPP group receiving mechanical ventilation decre
