[en] The capability of neonates to achieve cytokine balance was evaluated. Production of the pro-inflammatory cytokines TNF alpha and IL-8, of the natural anti-inflammatory cytokine IL10 and of the regulator of the acute phase response IL6 was assessed after whole blood stimulation by lipopolysaccharide in cord blood (n = 10), adult volunteers serving as control (n = 17). Additionally, circulating cytokines were determined in cord and in maternal blood immediately after delivery (n = 27, respectively). Significant production of TNF alpha, IL8, IL10 and IL6 was observed in cord blood after lipopolysaccharide stimulation and was similar to cytokine production in adult blood. The plasma concentrations of TNF alpha were significantly higher in cord than in maternal blood, while plasma concentrations of IL10 and IL6 were significantly lower. Our results demonstrate fully developed capability of whole cord blood to synthesize pro- and anti-inflammatory cytokines in response to a pro-inflammatory stimulation in vitro. In vivo, however, higher circulating TNF alpha and lower IL10 and IL6 levels in cord blood suggest that the inflammatory stress associated with normal delivery does not induce detectable anti-inflammatory response in neonates at birth.
