ABSTRACT
Objective To evaluate the accuracy of different biomarkers for early diagnosis of acute kidney injury ( AKI ) in the patients undergoing cardiovascular surgery under cardiopulmonary bypass ( CPB) . Methods A total of 200 patients, aged 22-86 yr, weighing 46-87 kg, scheduled for elective cardiovascular surgery under CPB, were enrolled in this study. The concentration of serum creatinine was determined at 1 day before operation and 1-7 days after operation. At 1 day before operation and 0, 2, 6 and 12 h after operation, the concentrations of urine neutrophil gelatinase-associated lipocalin (NGAL), cystatin C ( Cys C) , tissue inhibitor of matrix metalloproteinase type 2 ( TIMP-2) and insulin-like growth factor binding protein-7 ( IGFBP-7) were determined. The TIMP-2 and IGFBP-7 product ( TI) was calcu-lated. AKI was diagnosed after surgery according to Kidney Disease Improving Global Outcomes criteria. The receiver operating characteristic curve was plotted, and the area under receiver operating characteristic curve ( AUC) was calculated. Results The incidence of AKI was 20. 5%. The AUC of AKI diagnosed by the concentration of urine NGAL was 0. 689, 0. 709, 0. 713 and 0. 803 at 0, 2, 6 and 12 h after opera-tion, respectively ( P<0. 05) . The AUC of AKI diagnosed by the concentration of urine Cys C was 0. 639, 0. 762, 0. 774 and 0. 812 at 0, 2, 6 and 12 h after operation, respectively ( P<0. 05) . The AUC of AKIdiagnosed by TI was 0. 687, 0. 721, 0. 740 and 0. 779 at 0, 2, 6 and 12 h after operation, respectively ( P<0. 05) . The AUC of AKI diagnosed by combined three indices the parallel test was 0. 694, 0. 773 and 0. 794 at 0, 2 and 6 h after operation, respectively ( P<0. 05) . The AUC of AKI diagnosed by the serial test was 0. 610, 0. 631 and 0. 667 at 0, 2 and 6 h after operation, respectively. Conclusion Urine NGAL or Cys C concentrations or TI single detection and parallel test have a certain accuracy for early diag-nosis of AKI in the patients undergoing cardiovascular surgery under CPB.
