摘要:


文题释义:
孟德尔随机化:是一种利用遗传变异作为工具变量来研究暴露因素与疾病之间因果关系的统计方法。
肌萎缩侧索硬化症:是一种累及上、下运动神经元的进行性神经退行性疾病,主要表现为进行性肌无力和肌萎缩,其病程进展迅速,严重时可因呼吸衰竭致死。

背景:近期研究表明,肠道菌群可能会影响肌萎缩侧索硬化症的发展进程,然而两者之间的因果关系尚不清楚。
目的:利用孟德尔随机化方法探索肠道菌群与肌萎缩侧索硬化症之间的因果关系。
方法:从IEU Open GWAS数据库(由英国布里斯托尔大学的英国医学研究委员会和遗传流行病学研究所开发,旨在提供与多种疾病相关的全基因组关联研究数据,为开放数据库)中分别获取肠道菌群和肌萎缩侧索硬化症的GWAS数据,以肠道菌群为暴露因素、肌萎缩侧索硬化症为结局变量,使用逆方差加权法、MR-Egger回归法、加权中位数法、加权模型法和简单模型法来探究两者之间的因果关系。使用敏感性分析检验孟德尔随机化结果的可靠性,使用反向孟德尔随机化分析进一步验证两者间的因果关系。
结果与结论:①正向孟德尔随机化分析结果表明,6种肠道菌群与肌萎缩侧索硬化症之间存在因果关系,其中嗜胆菌属(β=0.206,OR=1.229)、毛螺菌属(β=0.288,OR=1.333)、马文-布莱恩特氏菌属(β=0.196,OR=1.216)、瘤胃球菌UCG010属(β=0.254,OR=1.289)和泰泽氏菌属3型(β=0.128,OR=1.136)可能是肌萎缩侧索硬化症的潜在危险因素,肠杆菌属(β=-0.203,OR=0.816)可能是肌萎缩侧索硬化症的保护因素;②在敏感性分析中,未发现显著的异质性和水平多效性(P均> 0.05),反向孟德尔随机化分析亦未揭示肠道菌群与肌萎缩侧索硬化症之间存在反向因果关系;③该研究结果不仅为肌萎缩侧索硬化症治疗提供了潜在的生物标志物,还为开发基于肠道菌群的新的干预治疗方案提供了理论依据,对中国基础医学研究具有一定的启示意义。

Abstract: BACKGROUND: Recent studies suggest that gut microbiota may have an influence on the progression of amyotrophic lateral sclerosis (ALS), but the exact causal relationship between them is still unclear.
Objective: To explore the causal relationship between gut microbiota and amyotrophic lateral sclerosis using Mendelian randomization analysis.
Methods: Genome-wide association study (GWAS) data on gut microbiota and amyotrophic lateral sclerosis were obtained from the IEU Open GWAS database (an open database developed by the UK Medical Research Council and the Institute of Genetic Epidemiology at the University of Bristol, UK, to provide GWAS data related to various diseases). Gut microbiota was used as the exposure factor and amyotrophic lateral sclerosis as the outcome variable. Inverse variance weighting, MR-Egger regression, weighted median, weighted model, and simple model methods were used to explore the causal relationship between them. Sensitivity analysis was conducted to assess the reliability of the Mendelian randomization results, and reverse Mendelian randomization analysis was further used to validate the causal relationship between the two.
Results and conclusion: (1) The results of the forward Mendelian randomization analysis indicated that there was a causal relationship between six types of gut microbiota and amyotrophic lateral sclerosis. Bilophila [β=0.206, odds ratio (OR)=1.229], Lachnospira (β=0.288, OR=1.333), Marvinbryantia (β=0.196, OR=1.216), RuminococcaceaeUCG010 (β=0.254, OR=1.289), and Tyzzerella3 (β=0.128, OR=1.136) may be potential risk factors for amyotrophic lateral sclerosis, while Intestinibacter (β=-0.203, OR=0.816) may be a protective factor for amyotrophic lateral sclerosis. (2) In the sensitivity analysis, no significant heterogeneity or orizontal pleiotropy was observed (P > 0.05), and the reverse Mendelian randomization analysis also did not reveal a reverse causal relationship between gut microbiota and amyotrophic lateral sclerosis. (3) The findings of this study not only suggest possible biomarkers for treating amyotrophic lateral sclerosis but also provide a foundation for creating new treatments using gut microbiota, with implications for fundamental medical studies in China.
