NEJM:靶向微生物群的补充食品用于治疗儿童营养不良

2021-04-08 MedSci原创 MedSci原创

研究认为,靶向微生物群的补充食品(MDCF-2)可作为中度急性营养不良儿童膳食补充剂,该研究同时证明了微生物组分调控与儿童生长发育的相关性

儿童营养不良是一个全球性的公共卫生健康问题,儿童营养不良与机体发育障碍、免疫和代谢功能障碍、中枢神经系统发育异常以及其他健康问题相关。据统计,全世界有3000多万儿童患有中度急性营养不良,其治疗效果有限,并且发病机制仍不清楚。有研究认为,中度急性营养不良儿童存在肠道微生物群紊乱。

近日研究人员考察了一种新型治疗性食品--靶向微生物群的补充食品(MDCF-2)对儿童营养不良的治疗效果。

研究人员在孟加拉国贫民窟招募了123名,年龄在12-18个月间的中度急性营养不良患儿,随机对参与患儿进行MDCF-2或常规食物补充(RUSF)干预,每天2次,持续3个月,然后进行1个月的监测随访。在基线检查时、干预期间每2周和第4个月时收集参与者体重、身高、年龄标准体重-身高z评分以及中上臂围数据,同时还测量了参与者血浆中4977种蛋白质水平和粪便样本中209种微生物水平。

共有118名儿童(每个研究组59名)完成了研究。在整个研究过程中,MDCF-2组在体重、身高和年龄标准体重z评分的变化方面优于RUSF组。MDCF-2组参与者,70种血浆蛋白水平,以及21个相关的肠道微生物分类群出现有益变化,其水平与年龄标准体重z评分呈正相关,而上述蛋白质在促进骨生长和神经发育方面发挥重要作用。
