摘　　要：背景天冬氨酸氨基转移酶(AST)/丙氨酸氨基转移酶(ALT)是近年来评估急危重症预后的新指标。目前AST/ALT仅报道可用于评估成人噬血细胞性淋巴组织细胞增生症(HLH)的预后,而儿童HLH尚未见相关研究。目的探讨HLH患儿AST/ALT与临床特征的关系及预后意义,为临床早期识别并诊断儿童HLH提供理论依据。方法选取2013年1月—2022年5月遵义医科大学附属医院确诊为HLH的128例住院患儿为研究对象,通过电子病历系统收集患儿的基线资料。将患儿按AST/ALT三分位数分为3组:T1组(AST/ALT≤1.57,n=43),T2组(1.57<AST/ALT<3.22,n=42),T3组(AST/ALT≥3.22,n=43)。采取门诊复查和电话随访形式对患儿进行随访。随访开始时间为患儿出院时间,每6个月随访1次,随访截至2022-06-01,终止事件为患儿死亡或失访。采用Spearman秩相关分析探讨AST/ALT与实验室检查结果的相关性。绘制实验室指标预测HLH患儿死亡的受试者工作特征曲线(ROC曲线),计算ROC曲线下面积(AUC)并计算最佳截断值。采用Kaplan-Meier法绘制生存曲线分析不同AST/ALT分组对患者总生存期的影响,并用Log-rank检验进行比较。采用Cox比例风险回归分析探讨HLH患儿死亡的影响因素。结果3组患儿性别、进入儿童重症监护室(PICU)情况、治疗方式比较,差异有统计学意义(P<0.05)。3组患儿呼吸衰竭、休克发生率比较,差异有统计学意义(P<0.05)。T3组患儿乳酸脱氢酶、肌酸激酶同工酶、血清铁蛋白和活化部分凝血活酶时间高于T1、T2组,白蛋白、纤维蛋白原水平低于T1、T2组(P<0.05);T2、T3组Na^(+)水平低于T1组,C反应蛋白水平高于T1组(P<0.05)。相关性分析结果显示,AST/ALT与中性粒细胞绝对值(r_(s)=0.182,P=0.040)、C反应蛋白(r_(s)=0.419,P<0.001)、总胆红素(r_(s)=0.182,P=0.040)、肌酸激酶同工酶(r_(s)=0.310,P<0.001)、乳酸脱氢酶(r_(s)=0.474,P<0.001)、活化部分凝血活酶时间(r_(s)=0.316,P<0.001)、血清�Background Aspartate aminotransferase(AST)/alanine aminotransferase(ALT)is a novel indicator to evaluate the prognosis of acute critical illness in recent years.At present,AST/ALT has only been reported to evaluate the prognosis of hemophagocytic lymphohistiocytosis(HLH)in adults,while HLH in children has not been studied.Objective To explore the relationship between AST/ALT and clinical characteristics and its prognostic significance in children with HLH,so as to provide a theoretical basis for early clinical recognition and diagnosis of HLH in children.Methods A total of 128 hospitalized children diagnosed with HLH in the Affiliated Hospital of Zunyi Medical University from January 2013 to May 2022 were selected as the research objects,and the baseline data of children were collected through the electronic medical record system.The children were divided into the T1 group(AST/ALT≤1.57,n=43),T2 group(1.57<AST/ALT<3.22,n=42),and T3 group(AST/ALT≥3.22,n=43)according to the AST/ALT quantiles,and followed up by outpatient review and telephone follow-up once every 6 months from the time of discharge to 2022-06-01,with the termination event of death or loss of follow-up.Spearman rank correlation analysis was used to explore the correlation between AST/ALT and laboratory test results.The receiver operating characteristic(ROC)curve of laboratory indicators for predicting death in children with HLHwas plotted,the area under ROC curve(AUC)and optimal cut-off value were calculated.Kaplan-Meier method was used to plot survival curves to analyze the effect of different AST/ALT groupings on overall survival,and Log-rank test was used for comparison.Cox proportional risk model was used to explore the influencing factors of death in children with HLH.Results There were statistically significant differences in gender,PICU admission,treatment methods,incidence of respiratory failure and shock among the 3 groups(P<0.05).Lactate dehydrogenase,creatine kinase isoenzyme,serum ferritin and activated partial thromboplastin time in t
