Serum metabolomic profile in children with sepsis-associated acute kidney injury

Nisha Chaudhary, Praveen Singh, Abhijeet Saha, Shantanu Sengupta

Clin Exp Pediatr. 2026;69(7):545-554. Published online April 15, 2026

Question: Can the potential metabolites/pathways involved in the pathogenesis of sepsis-associated acute kidney injury (SA-AKI) be identified using metabolomics?
Finding: We identified 18 novel metabolites involved in the pathogenesis of SA-AKI as well as 31 metabolites that were altered in severe AKI. Linoleic acid, linolenic acid, and phospholipid pathways were altered in SA-AKI.
Meaning: Once validated, these markers may be used to diagnose SA-AKI at an early stage before sufficient kidney injury occurs.
