研究疾病:

自身免疫性脑炎  

Target disease:

autoimmune encephalitis

研究疾病代码:

G04.801

Target disease code:

研究类型:

观察性研究

Study type:

Observational study

研究所处阶段:

研究设计:

横断面 

Study design:

Cross-sectional 

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.

纳入标准:

符合自身免疫性脑炎诊断标准的患者,新发的,未使用任何药物治疗的患者

Inclusion criteria

The participants were prospectively recruited from the follow-up of the Outcome of anti-NMDAR Encephalitis Study in Western China (ONE-WC) study, in which treatment naive patients with NMDAR encephalitis at initial onset had been diagnosed based on definitions of autoimmune encephalitis from a recent consensus statement.

排除标准:

患者和HCs的排除标准如下:1)受试者在取样前1个月内接受过抗生素或益生菌、益生元或任何免疫治疗;2)受试者在取样前1个月内经历过明显的腹痛、腹胀、腹泻或呼吸道感染;3) 入组前3个月内酗酒或其他物质(除烟草外)滥用或依赖;4)患有高血压、糖尿病等慢性病;5)其他自身免疫性疾病(类风湿关节炎、系统性红斑狼疮、1型糖尿病等)史;6)肠道手术史;7) 怀孕或哺乳期;以及8)神经精神疾病史[抑郁症、焦虑症、精神分裂症、多发性硬化症(MS)等]。

Exclusion criteria:

The exclusion criteria for both patients and HCs were as follows: 1) Participants had received treatment with an antibiotic or probiotics, prebiotics, any immune therapies within 1 months before sampling; 2) Participants had experienced significant abdominal pain, bloating, diarrhea or respiratory tract infection in the previous 1 months; 3) Alcohol or other substance (other than tobacco) abuse or dependence within 3 months prior to enrollment; 4) Participants with chronic diseases such as hypertension and diabetes; 5) History of other autoimmune diseases (rheumatoid arthritis, systemic lupus erythematosus, type 1 diabetes, etc.); 6) History of bowel surgery; 7) Pregnancy or lactation; and 8) History of neuropsychiatric disorders [depression, anxiety disorder, schizophrenia, multiple sclerosis (MS), etc.].
