Özet
Purpose: The recognition of acute kidney injury (AKI) as early as possible is important in the intensive care unit. This study proposes that serum and urine levels of neutrophil gelatinase-associated lipocalin (NGAL) may be used for this purpose.
Methods: One hundred and seven critically ill adult patients with no previous renal failure were included. NGAL levels were measured during the first 48 hours after admission; NGAL levels were followed for 7 days and classified based on Risk, Injury, Failure, Loss, and End-Stage Renal Failure criteria.
Results: The AKI incidence was 35.5%, and serum NGAL (sNGAL) and urinary NGAL (uNGAL) levels were higher in the AKI group. The area under the receiver operating characteristic curve was 0.76 (P<.001) for sNGAL and 0.75 (P<.001) for uNGAL. Seventy-one percent of AKI cases were observed within 48 hours, with 11 additional cases in the ensuing 7 days. The mean serum creatinine levels in the 11 patients were not different from non-AKI levels (P=.197), but the NGAL values were different, and the area under the receiver operating characteristic curve for sNGAL uNGAL was 1.00 (P=.014) and 0.93 (P=.02), respectively.
Conclusions: Most AKI cases were diagnosed within the first 48 hours after admission, and NGAL was useful for predicting upcoming AKI.
