CDSR:维生素A与患慢性肺病的风险及长期神经发育状态的关系

2021-09-10 从医路漫漫 MedSci原创

维生素A是肺正常发育和呼吸道上皮细胞完整性所必需的。早产儿出生时维生素A水平低,这可能与患慢性肺病的风险增加有关。

背景:维生素A是肺正常发育和呼吸道上皮细胞完整性所必需的。早产儿出生时维生素A水平低,这可能与患慢性肺病的风险增加有关。

目的:评估补充维生素A对极低出生体重儿(VLBW)死亡和/或新生儿慢性肺病和长期神经发育缺陷的发生率,并考虑补充途径,剂量和时间的影响。主要结果9项符合纳入标准的试验,8项比较补充维生素A与对照组(1291名婴儿),1项比较不同方案(120名婴儿)。

结果:与对照组相比,维生素A可能减少一月龄患儿的死亡率或氧气需求量(RR 0.93,95%CI 0.88-0.99;RD-0.05,95%CI -0.10至-0.01;NNTB 20,95%CI 10至1.00;1001名婴儿)。在最大型的试验中,88%的存活婴儿的神经发育评估显示,在18至22个月大的组之间没有差异,同时校正了早产。不同剂量的维生素A方案表现出相似的结果。

表 补充维生素A与不补充维生素A的比较

结论:目前尚不能证明补充维生素A与患慢性肺病的风险长期神经发育状态有关

Cell Host&Microbe:一种抗菌蛋白+维生素A,才能有效抵御皮肤细菌感染

众所周知,饮食中缺乏维生素A的人更容易导致皮肤感染,然而维生素A调节皮肤免疫力的机制仍然是个谜。近日发表在《Cell Host&Microbe》上的一项研究中,美国德克萨斯大学西南分校(UTSW)的研究人员通过确定表皮上一种过去未知的抗菌蛋白来揭示了这一谜团——它需要维生素A才能发挥作用。美国国立卫生研究院(NIH)的科学家们也参与了这项研究。研究人员发现,抵抗素样分子(RELM)家族中的

维生素A在免疫系统中的作用

维生素A (VitA)是一组含有脂环的不饱和一元醇。VitA不溶于水,但脂溶性。1928年,Green和Mellandy报道VitA可以增强机体的抗炎反应,并将VitA称为抗炎维生素。后来,在20世纪80年代和90年代,VitA的抗炎能力得到了广泛的研究。VitA以视黄醇、视网醇、视黄酸(RA)的形式存在,其中RA的生物活性最强。RA存在于两个重要的衍生物中:9-顺式RA和全反式RA (ATRA)
