在早产婴儿中补充Bifidobacterium BB-12增加了有益的肠道氨基酸和减少炎症标志物,从而改善了食耐受性. 这种益生菌干预措施对管理早产新生儿的炎症和食问题有希望.
科学领域:
- 新生儿营养和肠道微生物组研究.
- 在早产婴儿的免疫学和炎症途径.
- 益生菌对婴儿健康结果的影响
背景情况:
- 过早出生的婴儿往往会经历肠道失调和炎症.
- 食不耐受是早产新生儿的常见并发症.
- 特定益生菌,如Bifidobacterium BB-12在调节婴儿肠道健康中的作用正在调查中.
研究的目的:
- 为了研究Bifidobacterium BB-12对早产婴儿肠道代谢物的影响.
- 评估Bifidobacterium BB-12对血清炎症标志物的影响.
- 评估Bifidobacterium BB-12对食不耐症发生率的影响.
主要方法:
- 一项随机对照试验,涉及71名早产婴儿 (妊娠年龄≤32周).
- 婴儿被分配到益生菌组 (Bifidobacterium BB-12) 或对照组.
- 在2周和4周收集了便和血液样本,用于代谢物和炎症标志物分析 (TLR4,NF-κB,IL-1β,TNF-α).
主要成果:
- 益生菌组表现出更高水平的肠道氨基酸,包括谷氨胺,谷氨酸和 kynurenine.
- 在益生菌组中观察到炎症标志物 (TLR4,NF-κB,IL-1β,TNF-α) 的血清水平明显降低.
- 在接受Bifidobacterium BB-12的婴儿中,食不耐症的发生率明显较低.
结论:
- 施用Bifidobacterium BB-12会增加早产婴儿肠道中有益的氨基酸.
- 这种益生菌减少了关键的血清炎症标志物和促炎性细胞因子分泌.
- 补充Bifidobacterium BB-12可以缓解全身炎症,从而改善食耐受性并减少不耐受症的发生率.
