Background. Neutrophil gelatinase-associated lipocalin (NGAL) in serum and urine have been suggested as potential early predictive biological markers of acute kidney injury (AKI) in selected critically ill patients.Methods. We performed a secondary analysis of a multicenter prospective observational cohort study of unselected critically ill patients.Results. The analysis included 140 patients, including 57 patients who did not develop AKI, 31 patients who developed AKI, and 52 patients with AKI on admission to the ICU. Levels of sNGAL and uNGAL on non-AKI days were significantly lower compared to levels of sNGAL on RIFLERISKdays, RIFLEINJURYdays, and RIFLEFAILUREdays. The AUC of sNGAL for predicting AKI was low: 0.45 (95% confidence interval (CI) 0.27–0.63) and 0.53 (CI 0.38–0.67), 2 days and 1 day before development of AKI, respectively. The AUC of uNGAL for predicting AKI was also low: 0.48 (CI 0.33–0.62) and 0.48 (CI 0.33–0.62), 2 days and 1 day before development of AKI, respectively. AUC of sNGAL and uNGAL for the prediction of renal replacement therapy requirement was 0.47 (CI 0.37–0.58) and 0.26 (CI 0.03–0.50).Conclusions. In unselected critically ill patients, sNGAL and uNGAL are poor predictors of AKI or RRT.

BACKGROUND: Acute kidney injury (AKI) is a complication found in critically ill patients. Current consensus explains that diagnosis of AKI based on increased serum creatinine and decreased urine output. Neutrophil gelatinase-associated lipocalin (NGAL) level is increased a few hours after tubular damage occurred and can predict AKI more significantly than serum creatinine. Renal resistive index (RRI) is also a good marker in predicting the early stage of AKI. AIM: This study aimed to compare RRI and NGAL level as marker to predict incidence of AKI in critically ill patients treated in the Intensive Care Unit (ICU) at H. Adam Malik Hospital Medan. METHODS: This was an observational prospective cohort study and conducted in ICU at H. Adam Malik Hospital Medan in April-May 2021. This study had been approved by the Ethics Committee of Faculty of Medicine, Sumatera Utara University and H. Adam Malik Hospital Medan. Inclusion criteria are critical patients aged 18–65 years with 1st and 2nd priority level. Consecutive sampling was used. Resistive Index (RI) measured using USG Doppler by researcher and the results confirmed by ICU supervisors, while urine NGAL level measured within 3 h after ICU admission. Plasma urea and creatinine level measured after 24h after ICU admission. RESULTS: A total of 40 samples were collected; percentage of men and women are 66–35%, respectively (p = 0.001). There was a significant difference RI between AKI-group and non-AKI group (0.719 ± 0.060 and 0.060 ± 0.077, respectively) (p = 0.001). RI has a sensitivity of 71%, specificity of 84%, and accuracy of 87% in predicting occurrence of AKI with AUROC = 0.873. Meanwhile, NGAL has a sensitivity, specificity, and accuracy (66%, 89%, 78%, respectively) in early prediction of AKI incidence in critically ill patients. CONCLUSION: RI value was higher in AKI group than non-AKI group. RRI has better sensitivity than NGAL in predicting incidence of AKI.

Introduction: Acute Kidney Injury (AKI) is a common devastating problem in the NICU. Since the kidney is the second most affected organ in asphyxiated neonates (after the brain), a marker to determine kidney injury becomes important. Serum Neutrophil Gelatinase Associated Lipocalin (NGAL) determines acute kidney injury even before Blood Urea Nitrogen (BUN) or serum creatinine values rise. The aim of this study was to determine the clinical utility of NGAL as an early marker of acute kidney injury in asphyxiated neonates.Materials and Methods: This was a cohort study performed at a Level III NICU at JSS Hospital, Mysore, Karnataka, India over a period of two years. The study was conducted on30 term asphyxiated neonates and 30 term control neonates. Serum NGAL was measured within 6 hours after birth in an asphyxiated neonate using fluorescence immunoassay.Results: A highly significant increase in serum NGAL in cases group with a median of 323ng/ml as compared to control group with median of 64ng/ml was observed. Of the 30 asphyxiated neonates, 23 were positive for NGAL, and of these 3 had AKI.A cutoff value of 155 ng/ml for Serum NGAL could detect AKI in asphyxiated neonates with a sensitivity of 75% and a specificity of 23%.Conclusion: NGAL is raised in Asphyxiated neonates both with and without kidney injury. Therefore, it is not a specific marker for acute kidney injury in asphyxiated neonates.  J Nepal Paediatr Soc 2016;36(2):121-125.
