目的 探讨基线全身炎症反应指数(systemic inflammatory response index,SIRI)对腹膜透析(peritoneal dialysis,PD)患者腹膜透析相关性腹膜炎(peritoneal dialysis-related perito-nitis,PDAP)发生和预后的预测价值.方法 回顾性分析2014年1月—2020年12月于安徽医科大学第二附属医院行PD置管的140例患者为研究对象,根据是否发生PDAP分为腹膜炎组和非腹膜炎组,比较2组患者一般临床资料及实验室指标.采用二分类Logistic回归分析PDAP发生的危险因素,采用受试者工作特征(ROC)曲线评估基线SIRI对PDAP发生的预测价值.根据腹膜炎组的预后情况将其进一步分为治疗成功组与治疗失败组,分析腹膜炎治疗失败的危险因素.结果 腹膜炎组的SIRI(Z=-4.347,P<0.001)、白细胞计数(Z=-3.590,P<0.001)、血磷(Z=-5.499,P<0.001)、血清碱性磷酸酶(Z=-2.452,P=0.014)、总胆固醇(Z=-2.195,P=0.028)水平高于非腹膜炎组,差异有统计学意义.多因素Logistic回归分析显示:基线高 SIRI(OR=2.084,95%CI:1.054~4.121,P=0.035)、高血磷(OR=11.826,95%CI:4.204~33.262,P<0.001)及高血清碱性磷酸酶(OR=1.010,95%CI:1.002~1.019,P=0.022)是PDAP 发生的危险因素.ROC曲线结果显示SIRI的曲线下面积为0.720(95%CI:0.633~0.808,P<0.001),灵敏度和特异度分别为69.2%和 67.0%.高基线SIRI水平(OR=0.446,96%CI:0.208~0.959,P=0.039)是PDAP治疗失败的危险因素.结论 基线全身炎症反应指数与维持性腹膜透析患者发生腹膜透析相关性腹膜炎发生风险相关,对腹膜透析相关性腹膜炎的发生和预后有较好的预测价值.
Objective To investigate the predictive value of baseline systemic inflammatory response in-dex(SIRI)for peritoneal dialysis-associated peritonitis(PDAP)in peritoneal dialysis(PD)patients.Methods A total of 140 patients undergoing PD catheterization in the Second Affiliated Hospital of Anhui Medical Uni-versity from January 2014 to December 2020 were retrospectively analyzed.They were divided into peritoni-tis group and non-peritonitis group according to the presence or absence of PDAP.General clinical data and laboratory indexes were compared between the two groups.Binary logistic regression was used to analyze the risk factors for PDAP,and receiver operating characteristic(ROC)curve was used to evaluate the predictive value of baseline SIRI for the occurrence of PDAP.According to the prognosis in peritonitis group,the pa-tients were further divided into a successful treatment group and an ineffective treatment group;the risk fac-tors for peritonitis treatment failure were then analyzed.Results SIRI(Z=-4.347,P<0.001),white blood cell count(Z=-3.590,P<0.001),serum phosphorus(Z=-5.499,P<0.001),serum alkaline phosphatase(Z=-2.452,P=0.014),and total cholesterol(Z=-2.195,P=0.028)were significantly higher in the peritonitis group than in the non-peritonitis group.Multivariate logistic regression showed that higher SIRI(OR=2.084,95%CI:1.054~4.121,P=0.035),higher serum phosphorus(OR=11.826,95%CI:4.204~33.262,P<0.001)and high-er serum alkaline phosphatase(OR=1.010,95%CI:1.002~1.019,P=0.022)were the risk factors for PDAP.ROC curve showed that the area under the curve of SIRI was 0.720,with the sensitivity of 69.2%and specific-ity of 67%.Higher baseline SIRI level(OR=0.446,96%CI:0.208~0.959,P=0.039)was a risk factor for treat-ment failure of PDAP.Conclusions The baseline SIRI is associated with the risk of PDAP in PD patients,and is a good predictive indicator for the occurrence and prognosis of PDAP.
