Study design:

Factorial 

研究目的:

1、确定NMDAR脑炎和健康对照之间微生物群、代谢物(包括激素、氨基酸、外源性物质和脂质)和细胞因子的差异水平; 2、通过使用多变量建模整合广泛的临床表型、微生物组学、代谢组学和细胞因子数据,以了解肠道微生物生态系统; 3、分析这些信息是否与进一步复发的高风险和更差的临床结果相关。  

Objectives of Study:

1. Identify differential levels of microbiota, metabolites (ranging from hormones, amino acids, xenobiotics, and lipids) and cytokines between patients with NMDAR encephalitis and HCs; 2. Integrated extensive clinical phenotypic, microbiome, metabolomics, and cytokines data by using multivariate modeling to understand the gut microbial ecosystem, and its relevance, to NMDAR encephalitis; 3. Analyze if these information are associated with a high risk of further relapse and a worse clinical outcome.
