Total Cholesterol Concentration Predicts the Effect of Plasmapheresis on Hypertriglyceridemic Acute Pancreatitis
Abstract Background The clinical efficacy of plasmapheresis (PP) in patients with hypertriglyceridemic acute pancreatitis (HLAP) might affected by total cholesterol (TC). The objective of this study is to determine the relationship of TC and the Triglyceride (TG)-lowing effect in patients on either non-PP or PP therapy.MethodsPatients were categorized into high total cholesterol (HTC) /low total cholesterol (LTC) groups based on TC level of 12.4 mmol/l. The primary outcome was TG reduction to below 500mg/dl within 48 hours. Linear mixed-effect model and logistic regression analyses were used to assess the association of TC and different therapy groups on TG-lowing efficacy.ResultsCompared with LTC group, patients with HTC showed more severe imaging manifestations(p<0.001) and higher APACH Ⅱ scores (p=0.036). Deaths occurred only in HTC groups. Significant interaction of time sequence with the 2 TGs-lowing therapy groups on TG level was only found in HTC group (p < 0.001). In patients with elevated TC level, primary outcome occurred in 66.67% of patients in the PP group, and 27.91% in the non-PP group. After adjustment for age, gender, CT grade and APACH II score, the odd ratio remain significant (OR 5.47, 95% confidence interval [CI] 1.84-16.25, p = 0.002). Furthermore, in patients with lower TC level, primary outcome occurred in 81.25% of patients in the PP group, and 62.30% in the non-PP group (adjusted OR 2.05; 95% CI 0.45–9.40; p = 0.353).Conclusions: TC could be a potential biomarker to predict the effects of TG-lowing therapy in patients with HLAP.
