概括
病风险随着某些基因和质摄入量增加. 病毒感染,特别是秋季的呼吸道感染,与乳发作有关,但不仅仅是自身免疫.
科学领域:
- 免疫学 免疫学 免疫学
- 胃肠病学 胃肠病学
- 儿科 儿科 儿科
背景情况:
- 乳病 (CD) 的发展涉及遗传易感性和质暴露,但其他因素至关重要.
- 需要进行纵向研究,以了解感染和肠道微生物群对CD病变的影响.
- 青少年糖尿病的环境决定因素 (TEDDY) 研究为研究CD风险因素提供了有价值的队列.
研究的目的:
- 在TEDDY队伍中设计和建立一个案例和队列研究,以调查乳病发展中的环境和微生物因素.
- 分析病毒感染,肠道微生物群和乳性疾病自身免疫 (CDA) 和活检确认的乳性疾病 (CD-onset) 的发生之间的关联.
主要方法:
- 在TEDDY研究中设计了一个案例-队列研究,使用了TEDDY研究中6132名遗传风险儿童的数据.
- 持续的组织转胺酶自身抗体 (tTGA) 表明了乳性疾病自身免疫力 (CDA). CD-onset是由CDA定义的,其次是活检确认.
- 选择了561名儿童的子队列,包括所有306例CD发病病例,用于从纵向样本中分析病毒抗体和细菌体.
主要成果:
- 女性性别,HLA和非HLA基因,以及较高的谷蛋白消费与CDA和CD发病风险增加有关.
- 8月至10月期间报告的与病毒相关的呼吸道感染与CD发病风险增加相关,但不仅仅是CDA.
- 在MAVRiC研究中,将分析来自所选病例队列的血和便样本中的病毒抗体和细菌组.
结论:
- 除了遗传学和质之外,特定的病毒感染可能在引发乳病发作方面发挥作用.
- MAVRiC病例-队列研究有利于进一步阐明病毒和肠道微生物群在乳病病原发生中的作用.
- 了解这些环境触发因素可以为未来的乳病预防策略提供信息.

Factors Affecting the Risk of Infection
13.2K
The hosts' susceptibility to infection depends on several factors. The integrity of the skin and mucous membranes helps protect the body against microbial attacks. When the skin is altered, the chance of infection, limb loss, and even death increases.
The integrity and count of the white blood cells help the body resist pathogens and fight infection. When impaired, it reduces the body's resistance to pathogens. The acidic pH levels of the gastrointestinal, genitourinary tracts, and skin...

Fungal Phylum Microsporidia
387
Microsporidia are a group of obligate intracellular fungi that were initially classified as protists but were later reclassified based on phylogenetic, molecular, and structural evidence linking them to the Chytridiomycota. These unicellular, non-motile organisms are highly specialized parasites that infect a wide range of animal hosts, including humans. They have evolved extensive genomic and metabolic reductions, making them highly dependent on their hosts for survival.Morphology and Genomic...
