Study on the clinical significance of cytokines in neonates with hypoxic-ischemic encephalopathy / 中国免疫学杂志

ABSTRACT

Objective:To study the change of tumor necrosis factor-?(TNF-?) , interlukin-1?(IL-1?) and interluldn-6(IL-6) in neonates with hypoxic-ischemic encephalopathy(HIE) ,and analyze the relation between their levels and the severity of HIE. Methods:TNF-?,IE-? and IL6 in the plasma and in the supernatant of cultured peripheral blood mononuclearcytes(PBMC) were mesured in 50 neonates with HIE and 30 normal term neonates by enzyme-linked immunosorbent assay. Results: TNF-?and IL-?plasma levels and the production by PBMC in neonates with FILE were markedly elevated than those in normal controls Levels of TNF-?,IL-?and IL-6 both in the plasma and the supernatant of PB-MC were much higher in acute stage of severe HIE compared with the control group and mild HIE, and plasma levels of TNF-a and IL-? were significantly decreased in convalescence stage, but IL-6 levels were still much higher than those in normal controls. Conclusion:TNF-? and IL-? plasma levels and the production by PBMC in neonates with I-LIE axe related to the severity of HIE, and IL-6 may participate in the repair of neurons after ischemic brain injuly. These cytokines can be indicators of the brain damage degree of IDE.
