GUT:母乳的成分竟然可以预测早产儿发生坏死性小肠结肠炎!

2017-04-08 MedSci MedSci原创

坏死性小肠结肠炎(NEC)是早产儿中最常见且致命的肠道疾病之一。目前用于识别高危婴儿的标志物以及预防和治疗NEC的疗法是有限的。母乳喂养的NEC发病率明显低于配方喂养婴儿的发病率。婴幼儿配方奶中缺乏人乳寡糖(HMO),如二唾液酸乳酸-N-四糖(DSLNT),其可阻止新生大鼠的NEC。但是,DSLNT是否也能保护人类早产儿发生NEC至今尚未可知。近期,发表在杂志GUT上的文章进行了一项多中心临床队列

坏死性小肠结肠炎(NEC)是早产儿中最常见且致命的肠道疾病之一。目前用于识别高危婴儿的标志物以及预防和治疗NEC的疗法是有限的。


母乳喂养的NEC发病率明显低于配方喂养婴儿的发病率。婴幼儿配方奶中缺乏人乳寡糖(HMO),如二唾液酸乳酸-N-四糖(DSLNT),其可阻止新生大鼠的NEC。但是,DSLNT是否也能保护人类早产儿发生NEC至今尚未可知。

近期,发表在杂志GUT上的文章进行了一项多中心临床队列研究,此项研究招募了200名母亲及其极低出生体重的婴儿,主要采用人乳喂养。研究者们分析了喂养母乳中的HMO组成,在产后第28天对NEC病例进行了匹配,并采用Logistic回归和广义估计方程评估。

此项研究结果发现:在队列中的8名婴儿发展成NEC(Bell2级或3级)。与对照组相比,NEC病例中几乎所有牛奶样品中的DSLNT浓度均显着降低,其浓度可以在发病前预测发生NEC病例。多天的DSLNT综合评估增强了NEC病例和对照受试者的分离。

此项研究表明:母乳中的DSLNT含量是潜在的非侵入性标记物,用于鉴定发展为NEC的婴儿,并可以筛选出高风险的供体牛奶。此外,DSLNT可以作为开发针对这种疾病的新型治疗剂。
