Study design:

Factorial 

研究目的:

(1)通过观察受试者脑脊液代谢组学的变化,与治疗反应性、疾病复发的相关性,早期发现需要予以IVIg联合及重复使用的病人,为进一步确定抗NMDAR脑炎的治疗提供依据; (2)探讨脑脊液内代谢组学与鞘内NMDAR抗体合成的相关性。  

Objectives of Study:

(1) By observing the changes in CSF metabolome, and the relationship between the treatment and disease recurrence, to discover the patients requiring treatment in combination with IVIg or repeated IVIg treatment early, and to provide evidence to the treatment of anti-NMDAR encephalitis; (2) To explore the relationship between metabolomics and intrathecal antibody synthesis.

药物成份或治疗方案详述:

本研究利用代谢组学预测早期使用丙种球蛋白治疗抗N-甲基-D-天门冬氨酸受体(NMDAR)脑炎,通过观察受试者脑脊液代谢组学的变化,与治疗反应性的相关性,早期发现需要予以静脉注射免疫球蛋白(IVIg)联合及重复使用的受试者,为进一步确定抗NMDAR受试者的治疗提供依据,探讨脑脊液内代谢组学与鞘内NMDAR抗体合成的相关性。本研究拟纳入收入神经监护病房的抗NMDAR脑炎患者,按照中国自身免疫性脑炎诊治专家共识2017版对受试者进行激素冲击治疗,根据受试者对激素治疗效果的分为效果良好组(A组)和疗效欠佳组。对疗效欠佳的受试者进行IVIg治疗,观察受试者疗效,根据疗效分为效果良好组(B组)和疗效欠佳组(C组),采集受试者激素治疗开始前,IVIg治疗开始前和治疗开始2周后的脑脊液(CSF)和血清抗 NMDAR 抗体滴度及非靶向代谢组学,同时采集患者基本资料、神经系统和疾病其他相关指标。分析A、B及C三组CSF、血清抗NMDAR滴度下降值和代谢组学之间的相关性,分析三组之间癫痫发作持续时间(d),抗癫痫药物使用剂量及时间(d),精神症状持续时间(d)以及其他预后指标的差异。探讨有无特异标志物可以预测疾病的严重程度。
