摘　　要：目的了解老年脓毒症相关急性肾损伤(sepsis-associated acute kidney injury,SA-AKI)患者的肾功能恢复率、临床特点及危险因素。方法回顾性分析2018年1月至2019年12月就诊于解放军总医院国家老年疾病临床医学研究中心≥75岁的SA-AKI患者的临床资料。根据出院时肌酐(serum creatinine,Scr)恢复情况,患者分为恢复组(出院时Scr≤125%基线值)和未恢复组(出院时Scr>125%基线值)。AKI定义和诊断标准采用2012年改善全球肾脏病预后组织(Kidney Disease:Improving Global Outcomes,KDIGO)制定的标准。持续型AKI定义为AKI发生48 h时Scr无下降(>基线Scr水平)。结果192例患者中位年龄为87(84~90)岁,男性183例,占95.3%。患者出院时21.9%(42/192)患者肾功能未恢复,78.1%(150/192)肾功能恢复。肾功能恢复组与未恢复组相比,性别比例(P<0.05)、基线Scr(P<0.001)和基础eGFR(P<0.001)差异有统计学意义。肾功能未恢复组患者AKI确诊时Scr(P<0.05)、Scr峰值(P<0.001)水平较高,肾脏替代治疗(P<0.05)和机械通气(P<0.001)需要率明显增加,持续型AKI所占比例高(P<0.001)。多因素Logistic回归分析显示两组在基础eGFR(70~79:OR=0.258,95%CI:0.088~0.757,P<0.05;80~89:OR=0.132,95%CI:0.041~0.421,P=0.001;≥90:OR=0.096,95%CI:0.015~0.627,P=0.014)、机械通气(OR=6.715;95%CI:2.665~16.918;P<0.001)和持续型AKI(OR=6.706;95%CI:2.741~16.404;P<0.001)等方面差异显著。结论高龄老年SA-AKI患者肾功能大多数可恢复,基础eGFR升高是高龄老年SA-AKI患者肾功能恢复的保护因素,机械通气和持续型AKI是高龄老年SA-AKI患者肾功能恢复的危险因素。Objective To understand the recovery rate of renal function,clinical features,and risk factors in elderly patients with sepsis-associated acute kidney injury(SA-AKI).Methods A retrospective analysis was made of the clinical data of SA-AKI patients who were no less than 75 years old from the Chinese PLA General Hospital,National Clinical Research Center for Geriatric Diseases,from January 2018 to December 2019.According to recovery of serum creatinine(Scr)at discharge,the patients were divided into recovery group(Scr≤125%baseline value at discharge),and non-recovery group(Scr>125%baseline value at discharge).AKI was defned according to the 2012 Kidney Disease:Improving Global Outcomes(KDIGO)criteria.Persistent AKI was defined as no decrease of Scr(>baseline value)at 48 hours after the occurrence of AKI.Results The 192 patients had a median age of 87(84-90)years,and included 183 males(95.3%).At the time of discharge,the renal function was recovered in 78.1%(150/192)patients,and not recovered in 21.9%(42/192)patients.There were statistically significant differences between the recovery group and the non-recovery group in gender ratio(P<0.05),baseline Scr(P<0.01),and baseline eGFR(P<0.001).Compared with the recovery group,the non-recovery group showed higher Scr at diagnosis of AKI(P<0.05),higher peak Scr(P<0.001),higher rate of renal replacement therapy(P<0.05),higher rate of mechanical ventilation(P<0.001),and a higher proportion of persistent AKI(P<0.001).Multivariate logistic regression analysis revealed that there were statistically significant differences between the recovery group and the non-recovery group in baseline eGFR(70-79:OR=0.258,95%CI:0.088-0.757,P<0.05;80-89:OR=0.132,95%CI:0.041-0.421,P=0.001;≥90:OR=0.096,95%CI:0.015-0.627,P=0.014),in mechanical ventilation(OR=6.715,95%CI:2.665-16.918,P<0.001),and in persistent AKI(OR=6.706,95%CI:2.741-16.404,P<0.001).Conclusion The recovery rate of renal function in elderly patients with SA-AKI was 78%.The increased eGFR was a protective factor while mechanical
