评估母亲产前使用类固醇 (ANS) 对早产儿出生时脐带血细胞因子水平的影响。测量脐带血中促炎细胞因子(IL-1β、IL-6、IL-8)的浓度;抗炎细胞因子(IL-4、IL-10 和 TGF β);以及 200 名早产儿的神经营养细胞因子(BDNF、NT-3 和 NT-4)。使用多变量线性回归分析数据,以模拟 ANS 和炎症对平均对数脐带血细胞因子浓度的独立和联合影响,并根据胎龄和阿普加评分进行调整。暴露于 ANS 对本研究中测量的脐带血细胞因子浓度没有显着影响。在胎盘炎症婴儿中,所有三种促炎细胞因子水平和 IL-10 水平均显着升高,脐带血中 TGF-β 和 NT-3 水平显着降低。尽管暴露于 ANS 对脐带血细胞因子水平没有任何显着影响,但与胎盘炎症且未暴露 ANS 的母亲所生的婴儿相比,胎盘炎症且暴露于 ANS 的母亲所生的婴儿存在炎症反应减弱和神经营养细胞因子水平较高的趋势。
To evaluate the effect of maternal administration of antenatal steroids (ANS) on cord blood cytokine levels at birth in preterm infants. Cord blood cytokine concentrations were measured for pro-inflammatory cytokines (IL-1β, IL-6, IL-8); anti-inflammatory cytokines (IL-4, IL-10 and TGF β); and neurotrophic cytokines (BDNF, NT-3, and NT-4) in two hundred preterm infants. Data were analyzed using multivariable linear regression to model the independent and joint effects of ANS and inflammation on mean log cord blood cytokine concentrations adjusted for gestational age and Apgar scores. Exposure to ANS had no significant effect on the cord blood concentrations of cytokines measured in this study. All three pro-inflammatory cytokines levels and levels of IL-10 were significantly increased and cord blood levels of TGF-β and NT-3 were significantly decreased in infants with placental inflammation. Although exposure to ANS did not have any significant effect on cord blood levels of cytokines, there was a trend toward the attenuation of inflammatory response and higher levels of neurotrophic cytokines in infants born to mothers with placental inflammation and exposure to ANS compared to infants born to mothers with placental inflammation and no ANS exposure.
