概括
免疫吸附疗法在COVID后的ME/CFS患者中有效地消除了自主神经系统受体自身抗体. 这种治疗减少了促炎性细胞因子,改善了神经功能,尽管症状改善是有限的.
科学领域:
- 免疫学 免疫学 免疫学
- 神经学 神经学
- 传染性疾病 传染性疾病
背景情况:
- 自体抗体 (AAB) 与COVID后的疾病有关,特别是肌痛性脑筋炎/慢性疲劳综合征 (ME/CFS).
- 在一些COVID后的ME/CFS患者中观察到自主神经系统受体 (ANSR) 自体抗体和神经功能障碍.
- SARS-CoV-2 感染在诱发或加重 ME/CFS 症状中的作用需要进一步调查.
研究的目的:
- 评估免疫吸附治疗在COVID后的ME/CFS患者中的疗效.
- 分析这种治疗对免疫学参数的影响,包括ANSR自身抗体和细胞因子.
- 评估免疫学变化与临床结果之间的相关性.
主要方法:
- 对12名COVID后患有ME/CFS症状的患者进行观察性研究.
- 用免疫吸附疗法治疗以去除免疫球蛋白G抗体.
- 在治疗前后测量ANSR自身抗体,促炎性细胞因子,可溶性尖端蛋白和神经功能.
主要成果:
- 免疫吸附疗法几乎消除了ANSR自身抗体,并降低了免疫球蛋白G水平.
- 观察到促炎性细胞因子 (IL-4,IL-2,IL-1β,TNF,IL-17A) 和可溶性尖端蛋白的减少.
- 患者表现出神经心理功能和手握强度的改善,但自我报告的症状和ME/CFS得分没有显著改善. 蛋白质反弹发生在一个月内.
结论:
- 免疫吸附疗法可以有效地减少COVID后ME/CFS的特定自身抗体和促炎性标志物.
- 虽然神经功能可能会得到改善,但免疫吸附疗法对整体症状负担的影响需要进一步研究.
- 蛋白质去除的短暂性质和缺乏持续的症状缓解,需要进一步研究长期治疗策略.

Immunodeficiency Diseases
898
Immunodeficiency disorders are conditions in which the immune system's ability to fight infectious disease and cancer is compromised or entirely absent. The immune system comprises a complex network of cells, tissues, and organs that work together to protect the body from potentially harmful invaders. When this system is deficient or not functioning properly, it leaves the body susceptible to infections, diseases, or other complications.

Factors Affecting the Risk of Infection
11.3K
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...
