Increased umbilical cord plasma interleukin-1 beta levels was correlated with adverse outcomes of neonatal hypoxic-ischemic encephalopathy.
To explore whether or not the umbilical blood levels of cytokines can be used to indicate the adverse outcomes of hypoxic-ischemic encephalopathy (HIE) patients. Umbilical artery blood and peripheral venous blood samples were collected on the 1st, 3rd and 7th days after birth to detect the levels of IL-1 beta, IL-8 and TNF-alpha. Neurological examination and Denver developmental screening test (DDST-II) were performed at the 6 and 12 months evaluations to detect any neurodevelopmental abnormalities. The results showed: (i) the serum concentrations of IL-1 beta, IL-8 and TNF-alpha in umbilical and peripheral blood were significantly higher in HIE patients than control groups; (ii) the umbilical blood concentrations of IL-1 beta exhibited the best positive correlation with HIE grades, when compared with IL-8 and TNF-alpha; and (iii) abnormal neurological outcomes at 6 and 12 months of age were best predicted by umbilical levels of IL-1 beta. Thus, umbilical concentrations of IL-1 beta were associated with the grades and adverse outcomes of HIE.
