摘要:
背景: backgack: span in the随机受控的研究研究,概率地培养了临床的临床,这些临床的临床(trondemist)是临床的临床(trondemitigy)。后代特应性皮炎(AD)的发生率。在当前的研究中,我们假设效果是由T助手的转移介导的()儿童中的细胞。
客观: 检查该细胞比例是否受到孕妇益生菌补充的影响,因此可以介导益生菌对ad。在415名孕妇中,将鼠尾草lamnosus gg(LGG),动物动物杆菌的乳腺乳杆菌(LGG)摄入。在生命的头两年中,对乳酸BB-12(BB-12)和嗜酸乳杆菌LA-5(LA-5)或安慰剂进行了AD评估。 Peripheral blood collected at 3 months of age was analysed for regulatory T cells (n=140) and Th subsets (n=77) including Th1, Th2, Th9, Th17 and Th22.
RESULTS: The proportion of Th22 cells was reduced in children in the probiotic group compared to the placebo group (中值0.038%vs 0.064%,p = .009)。 P之间的区别在2年随访期间未发展AD的孩子中,还观察到了Robiotic和安慰剂组。与未发展AD的儿童相比,发展AD的儿童的Th22细胞比例增加(0.090%vs 0.044%,p <.001)。 Mediation analysis indicated that the preventive effect of probiotics was partially mediated through the reduction in Th22 cells.
CONCLUSION: Perinatal maternal probiotic supplementation with a combination of LGG, Bb-12 and La-5 reduced the proportion of Th22 cells in 3-month-old children.这可能部分解释了益生菌对AD的预防作用。
