  • 摘要:   目的  探讨酒精相关慢加急性肝衰竭(ALD-ACLF)合并感染患者短期预后影响因素,开发新的预后模型。  方法  选取2019年1月—2021年12月中国人民解放军总医院第五医学中心收治的89例ALD-ACLF合并感染患者为本次研究对象。以患者入组时为基线,收集其临床资料。根据患者28天生存情况分为生存组(n=53)和死亡组(n=36),对比两组患者基线临床资料。计量资料符合正态分布2组间比较采用t检验;不符合正态分布2组间比较采用Wilcoxon秩和检验。计数资料2组间比较采用卡方检验。多因素分析采用非条件Logistic回归分析;采用Z检验对受试者操作特征曲线(ROC曲线)下面积进行比较,评估模型诊断价值。  结果  死亡组患者与生存组相比,Hb(t=-2.397,P=0.019)、ALT(Z=-3.437, P=0.001)、GGT(Z=-2.617, P=0.009)、Cr(Z=-3.938, P<0.001)、BUN(Z=-3.423, P=0.001)、NH3Z=-4.406, P<0.001)、INR(Z=-3.428, P=0.001)、CRP(Z=-2.128, P=0.033)、PCT(Z=-2.441, P=0.015)、MELD评分(t=-4.817, P<0.001)、AKI发生率(χ2=21.602, P<0.001)、肺部感染发生率(χ2=4.866, P=0.027)、休克发生率(χ2=16.285, P<0.001)更高,Alb水平(Z=-2.473, P=0.013)、腹腔感染发生率(χ2=5.897, P=0.015)更低,差异均有统计学意义。多因素分析显示,NH3OR=1.027,95%CI:1.006~1.049, P=0.012)、MELD评分(OR=1.103,95%CI:1.011~1.203,P=0.027)、休克发生率(OR=6.326,95%CI:1.533~26.101,P=0.011)是ALD-ACLF合并感染患者28天死亡的独立危险因素。据此构建新的预测模型Y=0.027×NH3+0.098×MELD评分+1.845×休克-4.111。ROC曲线显示,新模型(曲线下面积为0.861,灵敏度为77.78%,特异度为88.68%)诊断价值高于MELD评分(曲线下面积为0.776,灵敏度为77.78%,特异度为67.92%),差异有统计学意义(Z=2.136,P=0.032 6)。  结论  ALD-ACLF合并感染患者短期预后不佳,MELD评分、NH3和发生休克是此类患者短期预后的影响因素,三者联合对短期预后的预测价值较高。
