Background: Gastroenteritis often correlates with acute kidney injury (AKI) in children who are hospitalized. The primary diagnostic test for acute kidney injury (AKI) in modern times is serum creatinine (SCr), which increases in the presence of AKI and is eliminated by glomerular filtration. SCr is an unsuitable biomarker for renal sickness because it lacks specificity and a slow response to disease severity or treatment changes. NGAL, or neutrophil gelatinase-associated lipocalin, is a molecular weight of 25 kDa protein and forms a covalent bond with neutrophil gelatinase. Elevations in NGAL levels due to kidney injury have important predictive value and may forecast the onset of acute kidney injury (AKI) 24-72 hours before an increase in diagnostic serum creatinine (SCr) values.
Aim and objectives: This study aims to determine whether plasma NGAL concentrations in mild, moderate, or severe dehydrated acute gastroenteritis patients may indicate acute kidney damage (AKI). The research will investigate whether acute renal injury and plasma NGAL concentrations are connected. Patients and methods: The cross-sectional design was employed in this study and included 80 patients who attended the pediatric gastrointestinal clinic at Babylon Children's Hospital. Between November 2022 and June 2023, all patients had gastroenteritis symptoms accompanied by different dehydration levels. Results: Patients with severe dehydration had considerable higher level of NGAL than those with mild to moderate dehydration (p<0.001). There was a notable inverse relationship (p = 0.046) between the NGAL level and potassium but a considerable direct link (p<0.001) between the NGAL level and creatinine. However, no significant correlation was seen between the NGAL level and urea (p = 0.404 and 0.062, respectively). The confidence range for the area under the curve (AUC) is 0.940 to 0.981, with a confidence level of 95%. The p-value is less than 0.001. The sensitivity is 88%. An accuracy of 88.4% has been attained. The NGAL cut-off point is 3.9832.
Conclusion: An analysis of plasma neutrophil gelatinase-associated lipocalin (NGAL) in individuals with gastroenteritis and varied degrees of dehydration indicated a clear and direct link between the two parameters. Specifically, when dehydration worsened, the average NGAL value increased
