NAT COMMUN:人类母体肠道菌群与婴儿食物过敏相关

2020-03-25 MedSci原创 MedSci原创

在最近的一项研究中,研究人员使用一个产前队列(n = 1064名母亲)进行嵌套病例队列研究,将58名具有临床证实的食物IgE介导的食物过敏的婴儿的母亲与258名随机选择的母亲进行比较。

在小鼠中,母体微生物群影响胎儿的免疫发育和出生后的过敏结果。西方人群过敏性疾病发生率高,普里沃氏菌在胃肠道中的含量低。

普里沃氏菌是一种共生细菌属,可以产生短链脂肪酸和内毒素,每一种都可能促进胎儿免疫耐受的发展。

在最近的一项研究中,研究人员使用一个产前队列(n = 1064名母亲)进行嵌套病例队列研究,将58名具有临床证实的食物IgE介导的食物过敏的婴儿的母亲与258名随机选择的母亲进行比较。

粪便样本中16S rRNA的V4区分析显示,如果母体在妊娠期间携带copri普雷沃氏菌,可以有力地预测其后代没有食物过敏。这种关联是通过靶向qPCR证实的,并且与copri普雷沃氏菌的婴儿期运输无关。

较大的家庭规模,一个公认的过敏疾病的保护因素,可以强烈预测孕妇携带copri普雷沃氏菌。

BMC Pediatr:儿童过敏性疾病发生的产前和新生儿因素研究

过敏性疾病,比如哮喘、皮炎、鼻炎和湿疹在中国学龄儿童中高度流行。环境因素,包括空气污染和汽车废气在这些疾病的病因中具有重要的作用。然而,产前和新生儿因素,包括性别、母亲怀孕期间疾病和早产,可能也于过敏性疾病的发生有关。最近,有研究人员在中国广州的小学和中学学生中,探索了与过敏性疾病相关的产前和新生儿因素。研究基于183449份调查问卷和医疗记录。数据表明,性别、出生体重、新生儿喂养类型、出生方法和

如何进行过敏原检测?

过敏已经成为一种全球性的富贵病,20%—40%的人一生中都曾罹患过敏性疾病,包括过敏性鼻炎、支气管哮喘、急性荨麻疹、婴儿湿疹、接触性皮炎、食物/药物过敏、过敏性休克等,其中过敏性休克是最致命的。
