摘要:

目的 探讨脓毒症急性肾损伤(AKI)患者血清 Nod 样蛋白受体蛋白 3(NLRP3)、白介素⁃18(IL⁃18)水平与病情严重程度的相关性。方法 选择2018年10月至2020年8月宁夏医科大学总医院ICU住院治疗的56例脓毒症患者,依据诊断标准将患者分为脓毒症组(26 例)和脓毒症 AKI 组(脓毒症轻度 AKI20 例,重度 AKI 10 例),选取同期 30 例健康体检者作为对照组,分别收集并比较各组一般资料,依据 28 d病死率将患者分为存活组(30 例)与死亡组(26 例),检测和比较各组血清中 NLRP3、IL⁃18 水平,分析血清 NLRP3、IL⁃18 与尿 NGAL、Kim⁃1 的相关性。分析影响患者预后的危险因素,绘制受试者工作特征曲线(ROC),评价独立危险因素单独及联合应用的预测价值。结果 与对照组比,脓毒症组与脓毒症 AKI 组NLRP3、IL⁃18 水平升高(P < 0.05),与脓毒症轻度 AKI 组比,脓毒症重度 AKI 组 NLRP3、IL⁃18 水平升高(P < 0.05)。与死亡组比,存活组 NLRP3、IL⁃18 水平降低(P < 0.05),NLRP3、IL⁃18 与尿 NGAL、Kim⁃1 均呈正相关。多因素 logistic 回归分析显示:血清 NLRP3 水平是影响脓毒症 AKI 死亡的独立因素。ROC 曲线分析显示:NLRP3、APACHE Ⅱ评分单独预测脓毒症 28 d 病死率的 AUC 分别为 0.72、0.73,敏感度分别为80%、85%,联合预测的 AUC 为 0.78,敏感度为 95%,优于单一指标(P < 0.05)。结论 血清 NLRP3、IL⁃18 水平与脓毒症AKI 患者病情严重程度密切相关。

Abstract:

Objective To investigate the correlation between serum NOD⁃like receptor protein 3(NLRP3)and interleukin ⁃18(IL ⁃18)and the severity of septic acute kidney injury(AKI). Methods In this prospectivestudy,56 patients with sepsis who were hospitalized in the ICU of the General Hospital of Ningxia Medical Universityfrom October 2018 to August 2020 were selected and divided into the sepsis group(26 cases)and sepsis AKI group(20 cases of mild AKI and10 of severe AKI)according to the Kidney Disease Improving Global Outcomes(KDIGO)diagnostic criteria,and 30 healthy subjects in the same period were selected as control group. The general data ofeach group were collected and compared. According to the 28⁃day mortality rate,the patients were divided intosurvival group(n = 30)and death group(n = 26). The level of serum NLRP3 and IL⁃18 was detected and com⁃pared,and the correlation between serum NLRP3,IL⁃18 and urine NGAL and Kim⁃1 was analyzed. Risk factorsaffecting the prognosis of patients with sepsis AKI were analyzed,and receiver operating characteristic curve(ROC)was drawn to evaluate the predictive value of independent risk factors alone and in combination. Results Compared with that in the control group,the level of NLRP3 and IL⁃18 in sepsis group and sepsis AKI group washigher than that in sepsis mild AKI group,and the level of NLRP3 and IL⁃18 in sepsis severe AKI group was higherthan that in sepsis mild AKI group(P < 0.05). Compared with that in the death group,the level of NLRP3 andIL ⁃18 in the survival group was lower,and the level of NLRP3 and IL ⁃18 was positively correlated with urinaryNGAL and Kim⁃1. Multivariate logistic regression analysis showed that serum NLRP3 was an independent factoraffecting the death of sepsis AKI(P < 0.05). ROC curve analysis showed that the area under the ROC curve(AUC) of NLRP3 and APACHEⅡ score for predicting 28⁃day mortality of sepsis was 0.72 and 0.73,and the sensitivitywas 80% and 85% respectively. AUC of the combined detection of the above two indexes was 0.78,and the sensi⁃tivity was 95%,which was better than that of the single indicator(P < 0.05). Conclusion The level of serumNLRP3 and IL⁃18 is closely related to the severity of AKI patients with sepsis.
