- Abstract: Objective To explore the diagnostic and prognostic values of procalcitonin(PCT),interleukin 6(IL-6)and cystatin C(CysC)combined detection in sepsis acute kidney injury(AKI).Methods A total of 100 patients with sepsis were divided into the AKI group(n=56)and the non AKI group(n=44)according to the occurrence of AKI.The prognosis of AKI patients was followed up,and patients were divided into the survival group(n=32)and the death group(n=24)according to the presence or absence of death.Enzyme-linked immunosorbent assay(ELISA)was used to detect PCT,IL-6 and CysC in different groups of patients.The Acute Physiological Function and Chronic Health Status Score(APACHEⅡ)was used to assess the condition of illness.ROC curve was used to analyze the predictive values of PCT,IL-6 and CysC in the diagnosis and death of sepsis combined with AKI.Results The male ratio,age,hypertension with diabetes ratio,APACHE Ⅱ score,serum creatinine(Scr),PCT,IL-6 and CysC levels were higher in the AKI group than those in the non AKI group,and the ratio of complications and onset time were lower in the AKI group than those in the non AKI group(P＜0.05).The ROC curve results showed that the area under the curve(AUC)of PCT,IL-6,and CysC combined for the diagnosis of sepsis complicated with AKI was 0.859,with a sensitivity of 91.07%and a specificity of 90.91%.The combined diagnostic efficacy was better than that of a single indicator.The APACHE Ⅱ score,PCT,IL-6 and CysC levels were higher in the death group than those in the survival group(P＜0.05).The ROC curve results showed that the AUC,sensitivity and specificity of PCT,IL-6 and CysC combined in predicting mortality in sepsis patients with AKI were 0.847,91.67%and 87.50%,respectively.The combined predictive efficacy was better than that of single indicator.Conclusion The combination of PCT,CysC and IL-6 indicators is more valuable in diagnosing and predicting prognosis of sepsis with AKI.
