Perinatal blood biomarkers for the identification of brain injury in very low birth weight growth-restricted infants.


ABSTRACT:

Objective

To determine if blood biomarkers measured at delivery and shortly after birth can identify growth-restricted infants at risk for developing severe brain injury.

Study design

In a cohort of very low birth weight neonates, fetal growth restricted (FGR) (birth weight <10%) were compared to non-FGR neonates, and within the FGR group those with brain injury were compared to those without. Biomarkers were measured in cord blood at delivery, and daily for the 1st 5 days of life.

Result

FGR was associated with significantly higher levels of interleukin (IL)-6, IL-8, IL-10, and lower levels of vascular endothelial growth factor (VEGF). FGR and brain injury were associated with significantly higher levels of IL-6, IL-8, IL-10, and glial fibrillary acidic protein (GFAP).

Conclusion

Interleukins may be involved in a common pathway contributing to both the development of growth restriction and brain injury, and GFAP may help identify brain injury within this growth-restricted group.
