概括
患有抗体阴性自身免疫脑炎 (AE) 的患者可以通过免疫疗法改善,尽管最初的严重残疾. 早期治疗和监测功能状况是这些研究不足的AE病例中更好的长期结果的关键.
科学领域:
- 神经免疫学 神经免疫学
- 神经学 神经学
背景情况:
- 抗体阴性自身免疫脑炎 (AE) 占AE病例的很大一部分,但仍未得到充分研究.
- 缺乏典型的AE定义特征的案例在研究中特别不足.
研究的目的:
- 描述被诊断为"仅可能"或"可能"自身免疫脑炎 (AE) 的患者的长期结果.
- 评估免疫治疗的疗效,并确定抗体阴性AE的长期预后的预测因素.
主要方法:
- 从2006年到2020年,对"只可能"或"可能但抗体阴性"AE的成年患者进行了回顾性分析.
- 纳入标准要求至少进行一年的随访;所有患者都接受了神经抗体测试.
- 收集的数据包括基线残疾 (修改的兰金尺度[mRS]),CSF和MRI发现,免疫治疗的时间和临床结果.
主要成果:
- 包括45名患者,随访时间中位数为36个月. 大多数在基线时呈现显著残疾 (mRS ≥3).

Immunological Memory
549
Immunological memory, a pivotal pillar of the adaptive immune system, is responsible for the body's ability to remember and respond more swiftly and effectively to previously encountered pathogens. This remarkable feature is what makes vaccines so effective in preventing diseases.
What is Immunological Memory?
Immunological memory is an integral function of the immune system that allows it to recognize and react more rapidly and effectively to pathogens previously encountered. This feature...

Myasthenia Gravis: Overview and Treatment
1.2K
Myasthenia gravis is a neuromuscular transmission disorder characterized by weakness and increased fatigability of skeletal muscles. It is an autoimmune disease affecting approximately one in 2000 people, where antibodies against the α1 subunit of nicotinic acetylcholine receptors are produced.
These antibodies interfere with the function of the nicotinic receptors in three ways: by binding to the receptor and disrupting acetylcholine binding; by causing cross-linking of receptors which...
