AIMS: A major complication of type 1 diabetes is diabetic kidney disease (DKD). Albuminuria and impaired glomerular filtration rate are the main characteristics of DKD. Neutrophil gelatinase-associated lipocalin (NGAL) levels may rise even in the early stages of DKD, even in patients with normoalbuminuria. We present the first systematic review and meta-analysis examining the prognostic role of NGAL exclusively in pediatric patients with type 1 diabetes.
METHODS: A search through major databases was carried out until September 24, 2024, investigating the prognostic role of NGAL in kidney injury in pediatric patients with type 1 diabetes. A p < 0.05 was considered statistically significant. A study quality assessment was conducted using the Newcastle-Ottawa Scale.
RESULTS: The standardized mean difference in urinary NGAL (uNGAL) levels between the type 1 diabetes group and healthy controls was statistically significant (SMD = 0.63, 95%CI [0.36,0.90]). A moderate positive relationship between uNGAL and ACR was identified (r = 0.53, 95 % CI [0.31-0.70]). The uNGAL revealed a high overall diagnostic accuracy (AUC = 0.881).
CONCLUSIONS: Urinary NGAL appears to be a valuable biomarker for early detection and understanding of DKD in individuals with type 1 diabetes. Future clinical studies should prioritize assessing the accuracy of NGAL in identifying kidney injury in pediatric patients with type 1 diabetes and the association of NGAL with traditional biomarkers in groups with similar characteristics.
