Association between inflammatory-response gene polymorphisms and risk of acute kidney injury in children

Area of Science:

• Genetics
• Pediatric Nephrology
• Immunology

Background:

• Acute kidney injury (AKI) is a significant concern in pediatric populations.
• Inflammatory response genes play a crucial role in various disease pathologies.
• Understanding genetic predispositions can aid in risk stratification for AKI.

Purpose of the Study:

• To investigate the association between polymorphisms in six key inflammatory-response genes (TNF, IL6, IL10, IL18, NFKB1, NFKBIA) and the risk of developing AKI in children.
• To identify potential genetic biomarkers for predicting AKI risk in pediatric patients.

Main Methods:

• Genotyping of 12 polymorphisms across six inflammatory-response genes in 1138 children with AKI and 1382 non-AKI controls.
• Logistic regression analysis was employed to calculate odds ratios (OR) and assess risk associations.
• Statistical adjustments were made for potential confounders, including Bonferroni correction.

Main Results:

• Significant associations with reduced AKI risk were found for three polymorphisms: NFKB1 rs28362491, NFKBIA rs2233406, and NFKBIA rs696 (P < 0.004).
• The NFKB1 rs28362491 polymorphism showed protective effects, with ORs of 0.75 (ID vs. II) and 0.44 (DD vs. II).
• NFKBIA polymorphisms rs2233406 (ORs 0.90 for CT, 0.43 for TT) and rs696 (ORs 0.71 for AG, 0.39 for GG) also demonstrated a reduced risk of AKI.

Conclusions:

• The study identifies NFKB1 rs28362491, NFKBIA rs2233406, and NFKBIA rs696 polymorphisms as potential predictive biomarkers for AKI risk in children.
• These genetic variations may contribute to understanding the underlying mechanisms of AKI susceptibility in pediatric patients.
• Further research is warranted to validate these findings and explore therapeutic implications.
