OBJECTIVES: In order to predict the late-development of chronic lung disease of prematurity (CLD), cytokines in the cord blood were assessed in this study. STUDY DESIGN: Eighteen premature infants with CLD were enrolled. Cord blood plasma levels of cytokines of these infants and 12 control infants without CLD were measured including interleukin (IL)-1beta, IL-2, IL-4, IL-6, IL-8, IL-10, interferon (IFN)-gamma, tumor necrosis factor (TNF)-alpha, soluble TNF receptor-I, and soluble IL-6 receptor using a cytometric bead array and an enzyme-linked immunosorbent assay. RESULTS: The cord blood IL-6, IL-8, and sTNFR-I levels were significantly elevated in CLD infants compared with those in control (P < .05). IL-1beta, IL-2, IL-4, IL-10, and IFN-gamma were undetectable in both groups. CLD infants with maternal chorioamnionitis had higher IL-6 than those without chorioamnionitis (P < .01). In CLD infants, IL-6 was higher in the infants who required prolonged oxygen therapy (P < .05). CONCLUSION: Elevated inflammatory cytokines in the cord blood are associated with the progression to CLD.
