Endovascular profiles linked to neutrophil activation in children and young adults with long COVID

Puntos clave

This research aims to investigate the relationship between endovascular profiles and neutrophil activation in children and young adults with long COVID.
Analyzed endothelial biomarkers and microclot burden in individuals with long COVID.
Examined the role of neutrophil markers and endothelial cytokines as potential biomarkers.
Elevated endothelial biomarkers were observed in children and young adults with long COVID.
Increased microclot burden was noted in the blood of affected individuals.
Neutrophil activation was linked to ongoing endovascular injury in long COVID.

Resumen

Children and young adults with long COVID display elevated endothelial biomarkers, underscoring disease-related rather than age-related endovascular profiles following SARS-CoV-2 infection. Children and young adults with long COVID exhibit increased microclot burden in blood. Neutrophil activation may contribute to ongoing endovascular injury in long COVID. A combination of microclots, neutrophil markers, and endothelial cytokines could serve as biomarkers for Long COVID.
