- 神经学 神经学
- 免疫学 免疫学 免疫学
- 临床诊断 临床诊断 临床诊断
背景情况:
- 自身免疫性脑炎 (AE) 诊断依赖于检测脑脊液 (CSF) 中的炎症变化,包括免疫球蛋白内合成 (IS).
- 及时的AE诊断和治疗对于患者的治疗结果至关重要.
研究的目的:
- 评估卡帕指数作为可疑AE患者IS的标志物.
- 评估卡帕指数与传统标记物,如橄克隆带 (OCB) 相比的灵敏度.

Encephalitis l: Introduction
27
Encephalitis is inflammation of the brain parenchyma, most often due to infections or autoimmune processes. It presents with neuropsychiatric features such as fever, altered mental status, behavioral changes, cognitive dysfunction, seizures, focal deficits, and sometimes autonomic instability. In some cases, the meninges are also involved, resulting in meningoencephalitis.Infectious CausesInfectious encephalitis is most commonly viral but can also result from bacterial, fungal, or parasitic...

Encephalitis ll: Pathophysiology
30
Encephalitis is inflammation of the brain parenchyma caused by direct viral invasion or immune-mediated mechanisms triggered by infections or tumors. Both processes lead to neuronal injury, disrupted neurotransmission, and diverse neurological symptoms, often with overlapping clinical and pathological features.Autoimmune EncephalitisIn autoimmune encephalitis, antibodies target neuronal antigens on cell surfaces, synapses, or within neurons. A key example is anti-NMDAR encephalitis, which can...
