Abstract:
Objective To evaluate the hypothesis that neutrophil gelatinase-associated lipocalin(NGAL) ,kidney injury molecule-1(KIM-1)and Interleukin-18(IL-18) are early biomarker for acute kidney injury (AKI) in patients after coronary artery bypass graft surgery(CABG) .Methods 80 patients were recruited during September 2011 to May 2012 .The patients were divided into two groups according to the AKI criteria ,patients developed postoperative AKI in AKI group ;others did not postoperative developed AKI in non-AKI group .Before and 2 ,4 ,6 ,8 ,12 ,24 h after the CABG surgery ,the urine and serum sample were collected ,serum creatinine ,the urine and serum IL-18、NGAL、KIM-1 value were test by ELISA method .Results 13 of 80 cases(16 .25% )developed postoperative AKI according to the AKI criteria ,diagnosis with serum creatinine was only 12-48 h after cardiac surgery .Concen-trations of NGAL 、IL-18 in urine and serum at 2 h after CABG surgery ,concentrations of KIM-1 in urine and serum at 6 h were the powerful independent predictors of AKI by logistic regression analysis and ROC curve .Conclusion IL-18 in urine and serum at 2 h after CABG surgery were the powerful independent predictors of AKI ,and concentrations of KIM-1 in urine and serum at 6 h were the powerful independent predictors of AKI .Serous NGAL and IL-18 is better than urinary NGAL and IL-18 in diagnosis of AKI . Urinary KIM-1 was better than serous KIM-1 in diagnosis of AKI at 6 h .
