The relationship between amniotic and newborn gastric fluid inflammatory mediators

摘要

Objective: To determine whether the levels of inflammatory mediators in gastric fluid (GF) of a premature newborn are associated with those in amniotic fluid (AF) of the newborn's mother. Patients: Twenty-three pairs of pregnant women and their premature newborns <35 weeks gestation, born by Cesarean sections. Methods: Amniotic fluids and newborn gastric fluids were obtained from women during Cesarean section procedure. The mother-premature newborn dyads were retrospectively assessed to analyze the clinical and laboratory data. Concentrations of interleukin-6 (IL-6), interleukin-8 (IL-8), tumor necrosis factor-alpha (TNF-α) and mannose-binding lectin (MBL) were compared between amniotic and newborn gastric fluids in each dyad. Results: Premature newborns and their mothers with funisitis had significantly higher median AF IL-6, TNF-α and GF IL-8 concentrations than those without funisitis (p=0.022 for AF IL-6; p=0.023 for AF TNF-α; p=0.022 for GF IL-8). The concentrations of IL-6, IL-8, TNF-α and MBL in newborn GF were significantly correlated with those in AF in each dyad (p<0.001, r=0.872 for IL-6; p<0.001, r=0.851 for IL-8; p<0.001, r=0.768 for TNF-α; p<0.001, r=0.845 for MBL, respectively). Conclusion: The levels of inflammatory mediators in GF of a premature newborn immediately after birth are strongly associated with those in AF of the newborn's mother.
