Background And AimThe use of therapeutic plasma exchange (TPE) for treatment of hypertriglyceridemia-induced acute pancreatitis (HTGP) remains controversial in the literature. This study compared the clinical outcomes of TPE versus conventional therapy in patients with HTGP.MethodsFifty-five patients with HTGP were included. Patients were retrospectively compared in pairs: those who received TPE treatment and those who did not, those whose triglyceride level fell below 500 mg/dL within 48 h, and those who did not, those with and without persistent organ failure. The primary outcome was the percentage of triglyceride reduction within 48 h. Secondary outcomes were the length of hospital stay, mortality, cost-effectiveness, and persistent organ failure.ResultsPercentage decrease in triglyceride levels, medical hospitalization costs, and length of hospital stay were higher in the TPE group compared to the non-TPE group (p < 0.05, for each). However, there was no difference regarding persistent organ failure and mortality (p > 0.05, for each). The length of hospital stay, average cost, persistent organ failure, and mortality were similar in both groups whose triglyceride level fell below 500 mg/dL within 48 h and those who did not (p > 0.05, for each). Among patients with persistent organ failure, average cost was higher in the TPE group compared to the non-TPE group (p < 0.05). An independent relation was found between the average cost and persistent organ failure, TPE, length of hospital stay, albumin, and urea values in all patients (p < 0.05, for each).ConclusionsThe approach of using TPE for treatment of HTGP was not found to be superior to the conventional treatment. Randomized controlled studies with larger number of patients are needed to gain better understanding of this issue.© 2024.
