Disruption of the Circulating Proteome in Neonates Receiving Extracorporeal Membrane Oxygenation Following Congenital Heart Disease Surgery: A Nested Case-Control Study

J Pediatr. 2025 Jan:276:114322. doi: 10.1016/j.jpeds.2024.114322. Epub 2024 Sep 19.

Abstract

This nested case-control study identified broad dysregulation of the circulating proteome in neonates receiving postoperative extracorporeal membrane oxygenation support after congenital heart disease surgery, including differential responses in those not surviving to hospital discharge. Tissue hypoxia and mitochondrial-associated proteins may represent novel candidate biomarkers for poor extracorporeal membrane oxygenation outcomes.

Keywords: ECMO; cardiac surgery; cardiopulmonary bypass; erythropoietin; protein biomarkers; proteomics.
