慢加急性肝衰竭患者非生物型人工肝支持系统治疗后总胆红素清除率与90天短期预后关系
Association between total bilirubin clearance rate following non-biological artificial liver support system therapy and 90-day short-term prognosis in patients with acute-on-chronic liver failure
目的 探讨慢加急性肝衰竭(Acute-on-chronic liver failure,ACLF)患者在接受非生物型人工肝支持系统(Artificial liver support system, ALSS)治疗后,其总胆红素的清除率(Total bilirubin clearance rate,TBCR)与患者90天短期预后的关系。 方法 选择2021年8月至2023年12月在赣州市第五人民医院接受血浆滤过透析(Plasma diafiltration,PDF)为中心的非生物型ALSS治疗的ACLF患者90例。收集患者相关临床信息,采用限制性立方样条分析TBCR与ACLF预后的关系,Cox回归模型分析与非生物型ALSS治疗ACLF患者90天预后的相关影响因素,受试者工作特征(Receiver operating characteristic, ROC)曲线评估预后预测指标的效能。 结果 90例患者的90天无移植生存率为56.67%。与90天死亡患者相比,90天无移植生存者疾病严重程度较轻(P<0.001),非生物型ALSS治疗次数更少(P<0.001),平均TBCR更高(P=0.010)。Cox回归分析显示,MELD评分[HR(95%CI):1.10(1.04~1.15),P<0.001],TBCR[HR(95%CI):0.13(0.04~0.43),P=0.001]和非生物型ALSS治疗次数[HR(95%CI):1.43(1.09~1.88),P=0.010]是预测不良短期预后的独立影响因素。限制性立方样条分析,TBCR与无移植生存率呈正相关[HR(95%CI):0.23(0.08~0.67),P=0.007]。TBCR在预测90天无移植生存率中的ROC曲线下面积(Area under curve,AUC)(95%CI)为0.658(0.543~0.772)(P=0.011),敏感度和特异度分别为62.7%和66.7%。对TBCR分层分析,与TBCR<42.6% ACLF患者相比,TBCR≥42.6% ACLF患者90天生存率更高(P=0.006)。 结论 在接受了非生物型ALSS治疗的患者中,TBCR与ACLF 90天短期预后呈正相关。因此,它可作为非生物型ALSS治疗ACLF的预后生物标志物。
Objective : To explore the relationship between the total bilirubin clearance rate (TBCR) of patients with acute-on-chronic liver failure (ACLF) after treatment with non-biological artificial liver support system (ALSS) and their short-term prognosis within 90 days. Methods A total of 90 patients with ACLF treated with the non-biological ALSS centered on PDF at The Fifth People's Hospital of Ganzhou from August 2021 to December 2023 were included in the study.Relevant clinical information of the patients was collected. The relationship between TBCR and the prognosis of ACLF was analyzed by restrictive cubic spline analysis. The Cox regression model was used to analyze the influencing factors related to the 90-day prognosis of ACLF patients treated with non-biological ALSS. The receiver operating characteristic (ROC) curve was used to evaluate the efficacy of prognostic predictive indicators. Results The 90-day transplantation-free survival rate of 90 patients was 56.67%. Compared with patients who died within 90 days, those who survived without transplantation within 90 days had a milder disease severity (P<0.001), fewer treatments for non-biological ALSS (P<0.001), and a higher average TBCR (P=0.010). Cox regression analysis showed that MELD score [HR(95%CI): 1.10(1.04-1.15), P<0.001], TBCR[HR(95%CI): 0.13(0.04-0.43), P=0.001] and the number of treatments for non-biological ALSS [HR(95%CI): 1.43(1.09-1.88), P=0.010] was an independent influencing factor for predicting poor short-term prognosis. Restricted cubic spline analysis showed that TBCR was positively correlated with transplantation-free survival rate [HR(95%CI): 0.23(0.08-0.67), P=0.007]. The Area under the ROC curve (AUC) (95%CI) of TBCR in predicting 90-day transplantation-free survival was 0.658(0.543-0.772) (P=0.011), and the sensitivity and specificity were 62.7% and 66.7%, respectively. Stratified analysis of TBCR showed that compared with ACLF patients with TBCR<42.6%, ACLF patients with TBCR≥42.6% had a higher 90-day survival rate (P=0.006). Conclusion Among patients who received non-biological ALSS treatment, TBCR was positively correlated with the 90-day short-term prognosis of ACLF. Therefore, it can be used as a prognostic biomarker for ACLF.
