概括
将IgG-免疫吸附 (IgIA) 与eculizumab (ECZ) 结合使用并没有显著改善神经复发症的小儿 Shiga毒素产生大肠杆菌血溶性尿素综合征 (STEC-HUS) 患者的结果. 然而,在严重的病例中,这种组合可以作为救援疗法.
科学领域:
- 儿科脏病学 儿科脏病学
- 神经学 神经学
- 免疫学 免疫学 免疫学
背景情况:
- 小儿 Shiga 毒素产生 Escherichia coli 血溶性尿素综合征 (STEC-HUS) 的神经并发症严重,缺乏确定的治疗方法.
- 补充激活与STEC-HUS病原发生有关,eculizumab (ECZ) 显示不一致的结果.
- 在成年人中,IgG-免疫吸附 (IgIA) 已经显示出有前途,促使人们对其与儿童神经系统STEC-HUS的ECZ组合进行研究.
研究的目的:
- 评估结合IgG-免疫吸附 (IgIA) 与eculizumab (ECZ) 在神经性STEC-HUS.US的儿科患者中的疗效.
- 为了比较用IgIA+ECZ治疗的患者与单独使用ECZ或支持性护理治疗的患者的结果.
主要方法:
- 一项多中心的回顾性研究包括儿童患者 (<18岁) 患有神经性STEC-HUS从2010年到2020年在法国.
- 患者被分为三组:IgIA + ECZ,单独ECZ和支持性护理 (历史对照).
- 主要结局是随访1年后的生存和神经学评估.
主要成果:
- 在42名儿童中,18名接受IgIA+ECZ,24名仅接受ECZ,27名接受支持性护理.
- 没有观察到生存时间的显著差异,尽管对照组有三个急性死亡,而治疗组没有.
- 在IgIA+ECZ组中,最初的神经严重程度较高,但在调整后,1年的神经结果在组之间没有显著差异.
结论:
- 在所有儿科神经学STEC-HUS病例中,不支持IgIA+ECZ的常规组合.
- 这种组合可以被认为是严重的STEC-HUS与神经参与的潜在救援疗法.

3.4K
Transcytosis is the process in which molecules are internalized by endocytosis, transported across the cell, and released through exocytosis from the opposite end of the cell. Molecules such as insulin, immunoglobulins, and certain nutrients are transferred through the recycling endosomes by recycling and transcytosis.
IgG molecules from a mother undergo transcytosis starting around 13 weeks of gestation. The amount of IgG transferred and entering the fetal blood circulation increases with...

Bacterial gastroenteritis, characterized by diarrhea, abdominal cramps, and vomiting, is often caused by ingestion of contaminated food or water and is frequently associated with pathogenic Escherichia coli strains. These microbes exploit two principal mechanisms to inflict disease.Shiga toxin–producing E. coli, also referred to as STEC—notably O157:H7—release Shiga toxins that target ribosomes, blocking protein synthesis. The B subunit of the toxin binds the host glycolipid...
