Recently it has been found that NGAL can also predict chronic kidney disease progression. Steroid resistant nephrotic syndrome has been found to be one of the important cause of&nbsp; chronic kidney disease in children. Therefore this study was conducted to evaluate whether urinary NGAL can correlate with proteinuria or glomerular filtration rate (GFR) in idiopathic nephrotic syndrome in children.</p><p><strong>Objectives:</strong>To find out the correlation between urinary NGAL with proteinuria and GFR in childhood idiopathic nephrotic syndrome.</p><p><strong>Materials and Methods:</strong>This cross-sectional was conducted in the Department of Pediatric Nephrology, Dhaka Shishu Hospital and Department of Pediatric Nephrology, Bangabandhu Sheikh Mujib Medical University from June 2014 to May 2015. Fifty-one children with idiopathic nephrotic syndrome were enrolled for the study. Urinary NGAL was measured using a commercially available HUMAN NGAL/LIPOCALIN 2 ELISA kit.The estimated GFR (eGFR) was calculated using revised Schwartz formula as follows: eGFR (ml/min/1.73m<sup>2</sup>) = 0.413 x (height in centimeters/ serum creatinine in mg/dl). Correlation analysis of logarithmic value of uNGAL with logarithmic value urinary protein creatinine ratio and correlation analysis of logarithmic value ofuNGAL with&nbsp;&nbsp;&nbsp; logarithmic value of estimated GFR were assessed by using Spearman rank correlation test.</p><p><strong>Results:</strong>Among 51 children, 38 were in relapse and 13 were in remission. Urinary NGAL demonstated a significant (p&lt;0.001) positive correlation with spot urine protein creatinine ratio. There was no significant correlation between urinary NGAL levels and GFR.</p><p><strong>Conclusion:</strong>Urinary NGAL level significantly correlated with INS relapse but not with glomerular filtration rate.</p><p>JAFMC Bangladesh.
