ABSTRACT

Objective To explore the diagnosis value of serum cystatin C (Cys C),neutrophil gelatinase-associated lipocalin (NGAL) and urinary interleukin-18 (IL-18) levels in critically cases from pediatric Intensive Care Units (ICU).Methods 114 cases from June 2015 to January 2017 in Xidian Group Hospital were enrolled in the study.According to whether cases secondary to AKI,they were divided into AKI group (64 cases) and non-AKI group (50 cases).At same time 50 healthy cases were selected as the control group.The Serum creatinine (Scr),urinary nitrogen (BUN),Cys C,NGAL and urinary IL-18 levels were measured in each subject.The relationship between the indexes of AKI group was analyzed by Pearson analysis.The value of serum Cys-C,NGAL and urinary IL-18 in the diagnosis of AKI was analyzed by receiver operating characteristic (ROC) curve.Results Serum Cys-C,NGAL and urinary IL-18 levels of the AKI group were higher than that of the non-AKI group and the control group,the difference had statistical significance (t=3.137~28.642,t1 =7.653~33.672,all P<0.05).The levels of serum Cys-C and NGAL were positively correlated with Scr levels (Beta=0.273,0.514,all P<0.05).The urinary IL-18 levels were negatively correlated with serum albumin (Alb) (Beta =-0.342,P<0.05).The area under the ROC carve (AUC) of serum Cys-C,NGAL and urinary IL-18 was 0.872 (95% CI:0.831~0.936),0.823 (95% CI:0.641~0.925) and 0.714 (95%CI:0.598~0.833).Conclusion The levels of serum Cys-C and NGAL were elevated earlier than Scr,and it can be used as reliable indicators of early diagnosis of early cases AKI in ICU.
