ABSTRACT
Objective To evaluate the value of urine neutrophil gelatinase-associated lipocalin (uNGAL) to early diagnose acute kidney injury(AKI) of critically ill children in PICU.Methods Eighty critically ill children at PICU of Children's Hospital Affiliated to Shanghai Jiaotong University were enrolled in this study from April to June 2013.They were continuously observed for 72 hours.According to pediatric RIFLE criteria for diagnosis of AKI,patients were divided into AKI group (15 cases) or non-AKI group (65 cases).Additionally,according to sepsis diagnostic criteria,patients were divided into sepsis group (31 cases) or non-sepsis group (49 cases).The levels of serum creatinine and uNGAL were measured within 6th hour,24th hour,48th hour,72th hour after admitted to PICU.The differences of uNGAL levels between AKI and non-AKI groups,sepsis without AKI and non-sepsis non-AKI groups,sepsis merged AKI and sepsis without AKI groups were analysed.The sensitivity and specificity of uNGAL and serum creatinine for diagnosis of AKI at 48th hour were evaluated by ROC curve.Results Thirteen cases of eighty children developed to AKI after admitted to PICU.(1)The uNGAL levels [M(QR),ng/ml] in AKI group within 6th hour,at 24th hour,48th hour,72th hour were 863.00 (696.00),700.50 (580.00),365.50 (285.00),289.50 (319.30),respectively,which were significantly higher than those in non-AKI group [20.00 (106.00),20.00 (85.30),20.00(101.00),20.00(36.00)] (P <0.01).(2)The uNGAL levels in new developed group were much higher than those in non-AKI group at each time point.The comparision of serum creatinine at 48th hour was statistic difference.(3)The uNGAL levels rised at early stage in sepsis without AKI group and down to normal gradually after 48th hour.(4)The uNGAL levels continued increasing in sepsis merged AKI group,and had significant differences comparing with sepsis without AKI group(P < 0.01).(5) The areas under ROC curve of uNGAL and serum creatinine at 48th hour were 0.902(95% CI0.801 ~ 1.004) and 0.801 (95% CI0.768 ~ 0.981),respectively.Conclusion The level of uNGAL has earlier increase for 24 to 48 hours than that of serum creatinine in critically ill children,and it can also reflect the severity of AKI.Therefore it can be used as an early diagnostic biomarker for AKI in PICU.
