摘要:

目的 探讨凝血功能指标联合血清胱抑素 C(CysC)对脓毒症引起急性肾损伤(AKI)患者预 后的预测价值。方法 选择 2018 10 月至 2020 6 月宁夏医科大学总医院重症监护病房(ICU)住院治 疗的脓毒症 AKI 患者作为研究对象。按 28 d 转归将患者分为死亡组和存活组。收集两组患者性别、年 龄、既往史、急性生理学与慢性健康状况评分Ⅱ(APACHEⅡ)、血小板计数(PLT)、凝血酶原时间(PT)、活 化部分凝血活酶时间(APTT)、纤维蛋白原(Fib)、D⁃二聚体、抗凝血酶Ⅲ(ATⅢ)活性、蛋白 C(PC)活性、蛋 S(PS)活性等凝血指标及 CysC 等实验室资料。采用单因素和多因素 logistic 回归模型分析影响脓毒症 AKI 患者预后的危险因素,绘制受试者工作特征曲线(ROC 曲线)评估相关指标对预后的预测价值。采用 Spearman 相关分析法分析凝血指标与血清 CysC 的相关性结果 最终 78 例脓毒症 AKI 患者纳入结果分 析,其中男 55 例(70.51%),女 23 例(29.49%),男和女比例为 2.39∶1;年龄 19 ~ 86 岁,平均(59.3 ± 16.2)岁; 28 d死亡36例,病死率为46.2%。单因素分析显示:死亡组PT、APTT、D⁃二聚体、CysC、APACHEⅡ评分均明 显高于存活组[PT(s):(18.0 ± 2.3)比(16.3 ± 2.9),APTT(s):(42.7 ± 7.1)比(38.1 ± 7.1),D⁃二聚体(mg/L): 6.8(5.6,9.7)vs. 5.5(3.0,8.7),CysC(mg/L):(3.1 ± 1.4)vs.(1.9 ± 1.0),APACHEⅡ评分(分):(26.1 ± 5.7)vs. (19.2 ± 4.4),均P < 0.01],Fib和PLT均明显低于存活组[Fib(g/L):1.7(1.4,2.1)vs. 2.8(1.8,3.7),PLT(×109 /L): 81.9 ± 32.8)vs.(128.7 ± 64.6),均 P < 0.01]。两组间性别、年龄、既往史、ATⅢ、PS、PC 比较差异均无统计 学意义(均 P > 0.05)。多因素 logistic 回归分析显示:Fib、PLT、CysC APACHEⅡ评分均是影响脓毒症 AKI 患者预后的独立危险因素[优势比(OR)和 95%置信区间(95%CI)分别为 0.24(0.09 ~ 0.67),0.97(0.95 ~ 0.99),2.28(1.06 ~ 5.38),1.40(1.14 ~ 1.72),均 P < 0.01]。ROC 曲线分析显示:APACHEⅡ评分、Fib、CysC PLT 单独预测脓毒症 AKI 28 d 病死率的 ROC 曲线下面积(AUC)分别为 0.84、0.77、0.76、0.75,均 P < 0.05 且以四者联合检测(AUC = 0.95)的预测价值优于单一指标(P < 0.05)。相关性分析显示:PT、APTT CysC 均呈显著正相关(r 值分别为0.31、0.49,均P < 0.01)。结论 Fib、PLT、CysC、APACHEⅡ评分可作为脓毒症 AKI 患者预后的评价指标。

Abstract:

Objective To explore the prognostic value of coagulation function index combined with serum cystatin C(CysC)in patients with acute kidney injury(AKI)caused by sepsis. Methods A prospective study was performed. Seventy ⁃eight patients with septic AKI hospitalized in the ICU of Ningxia Medical University General Hospital from October 2018 to June 2020 were selected and divided into death group and survival group according to the 28⁃day outcome. Clinical data such as sex,age,past medical history,acute physiology and chronic health evaluation Ⅱ(APACHE Ⅱ)score and laboratory indexes such as platelet count(PLT),prothrombin time(PT), activated partial clotting enzyme live time(APTT),fibrinogen(Fib),D ⁃ dimer,antithrombin Ⅲ(AT Ⅲ)activity activity of protein C(PC),protein S(PS)activity and serum CysC were collected and compared in the two groups. Univariate and multivariate logistic regression were used to analyze the risk factors affecting the prognosis ofpatients with septic AKI. And receiver operating characteristic(ROC)curve was drawn to evaluate the prognostic value of related indicators. Spearman correlation analysis was used to analyze the correlation between coagulation function index and serum CysC. Results All the 78 patients with septic AKI were included in the final analysis including 55 males(70.51%)and 23 females(29.49%),with a ratio of 2.39∶1. The age ranged from 19 to 86,and the average age was(59.3 ± 16.2). Thirty⁃six patients died after 28 days,with a fatality rate of 46.2%. Univariate analysis showed that the score of PT,APTT,D⁃dimer,serum CysC and APACHEⅡ in death group were signifi⁃ cantly higher than those in the survival group[PT(S):18.0 ± 2.3 vs. 16.3 ± 2.9,APTT(S):42.7 ± 7.1 vs. 38.1 ± 7.1,D⁃dimer(mg/L):6.8(5.6,9.7)vs. 5.5(3.0,8.7),CysC(mg/L):3.1 ± 1.4 vs. 1.9 ± 1.0,APACHEⅡscore 26.1 ± 5.7 vs. 19.2 ± 4.4,both P < 0.01). Fib and PLT in the death group were significantly lower than those in the survival group[Fib(g/L):1.7(1.4,2.1)vs. 2.8(1.8,3.7),PLT(× 109 /L):81.9 ± 32.8 vs. 128.7 ± 64.6,both P < 0.01]. Sex,age,past medical history,ATⅢ,PS and PC in the two groups showed no significant difference(All P > 0.05). Multivariate logistic regression analysis showed that Fib,PLT,serum CysC and APACHEⅡ score were independent risk factors for the prognosis of septic AKI patients[odds ratio(OR)and 95% confidence interval (95%CI)respectively were 0.24(0.09 ~ 0.67),0.97(0.95 ~ 0.99),2.28(1.06 ~ 5.38),1.40(1.14 ~ 1.72)All P < 0.01]. ROC curve analysis showed that the area under ROC curve(AUC)of APACHEⅡ score,Fib,serum CysC and PLT for predicting mortality on 28 days of sepsis AKI was 0.84,0.77,0.76 and 0.75,respectively (All P < 0.05). The predictive value of the combination of the 4 indexes(AUC = 0.95)was better than that of the single index(P < 0.05). Correlation analysis showed that PT,APTT and CysC were significantly positively corre⁃ lated(r value was 0.31,0.49,respectively P < 0.01). Conclusion Fib,PLT,serum CysC and APACHEⅡ score can be used as prognostic indicators for patients with septic AKI.
