Abstract:
Objective To assess the detection of urinary neutrophil gelatinase associated lipocalin (NGAL) and blood prohibitin (PHB) levels in early diagnosis of children with acute kidney injury (AKI).Methods One hundred and twenty children with severe allergic purpura,sepsis,kidney disease or heart disease admitted from June 2011 to June 2013 in our hospital were enrolled,including 60 cases with AKI and 60 cases without AKI;and 60 healthy children were selected as the control group.The urinary NGAL and blood PHB levels were measured with ELISA method.Results At d1 after diagnosis,the urinary NGAL level in severe AKI group [(146.76 ±61.22) μg/L] was higher than that in non-AKI group [(21.79 ± 17.31) μg/L] and control group [(17.42 ± 13.11) μg/L] (t =15.430 and 22.216,P ＜ 0.01).At d2 after diagnosis,the urinary NGAL level in severe AKI group [(82.31 ± 44.76) μg/L] was higher than that in non-severe AKI group [(21.56 ± 28.56) μg/L] (t =8.863,P ＜0.01).At d1 of diagnosis,the blood PHB level in severe AKI group was higher than that in non-severe AKI group [(14.03 ±6.43) vs.(8.01 ± 6.13),t =11.271,P =0.004];blood PHB in severe AKI group was higher than that in non-AKI group [(10.63 ± 4.21) vs.(8.00 ± 4.76),t =7.051,P =0.017].The levels of urinary NGAL and serum PHB gradually decreased over time in children with severe AKI.The area under the ROC curve (AUC) of urinary NGAL and blood PHB for diagnostic of AKI were 0.833 and 0.952 (P ＜ 0.01),respectively.The diagnostic rate of the combination of the two parameters was 100％.Conclusions The diagnostic value of PHB alone or NGAL in AKI still may be improved.The detection of PHB combined with NGAL can make up each other and improve the diagnosis of AKI,which contribute to the early diagnostic of AKI for clinical workers and provide effective intervention measures,and then reduce the mortality.
