Abstract:
Objective To estimate the value of urinary neutrophil gelatinase-associated lipocalin (NGAL) level for early diagnosis of acute kidney injury (AKI) in patients with sepsis.Methods One hundred and twenty-six sepsis patients admitted to intensive care unit (ICU) in Baoshan Branch Hospital of Shuguang Hospital Affiliated to Shanghai University ofTraditional Chinese Medicine from June 2014 to December 2015 were enrolled, and they were divided into two groups according to whether complication of AKI was present. The levels of urinary NGAL in the two groups of septic patients were evaluated immediately and at 12, 24 and 48 hours after the definite diagnosis, and the levels were compared between the two groups; the receiver operating characteristic curve (ROC curve) was performed and the value of urinary NGAL level in early diagnosis of sepsis AKI was evaluated.Results There were 60 septic cases complicated with AKI (AKI group), with the prolongation of time after definite diagnosis, the urinary NGAL (g/L) levels were gradually increased at 12, 24 and 48 hours, the levels were significantly higher than those at the corresponding time points in the group without AKI [non AKI group (66 cases), 12 hours: 178.2±32.8 vs. 53.8±10.4, 24 hours: 228.4±24.6 vs. 54.1±9.0, 48 hours: 186.1±43.6 vs. 52.5±9.4, allP < 0.05]. The area under ROC curve (AUC) of urinary NGAL level at 24 hours after definite diagnosis and 95% confidence interval (CI) were 0.863 (0.766-0.929) and 0.686 (0.466-0.696), respectively, when the cutoff value of urinary NGAL was 65.9μg/L, the sensitivity was 81.9% and specificity 76.1%; when the cutoff value of urinary NGAL was 57.9μg/L, the sensitivity was 70.2% and the specificity 57.2%.Conclusion Urinary NGAL level can be used as a reference marker for the early diagnosis of sepsis concomitant AKI.
