Human perinatal asphyxia: correlation of neonatal cytokines with MRI and outcome.
Clinical studies of the preterm neonate and animal models of asphyxial brain injury both support a role for proinflammatory cytokines in central nervous system (CNS) injury. There are fewer studies of perinatal CNS injury in the full-term neonate. We have performed a prospective cohort study of full-term infants with perinatal asphyxia. Using archived neonatal blood samples, we have analyzed the serum levels of several proinflammatory cytokines. Preliminary results demonstrate an increase in IL-1, IL-6, and TNF-alpha in those children who are deceased at 1 year or who have a diagnosis of cerebral palsy versus those with normal neuromotor outcome. Further analysis will include correlations of cytokine levels with injury on MRI spectroscopy, with neonatal clinical markers of encephalopathy, and with later neurodevelopmental outcome.
