摘要

摘要: 目的鉴定与类风湿关节炎(rheumatoid arthritis, RA)、系统性红斑狼疮(systemic lupus erythematosus, SLE)和强直性脊柱炎(ankylosing spondylitis, AS)相关的肠道微生物群。方法利用已发表的全基因组关联研究(genome-wide association study, GWAS)和肠道微生物群GWAS的总结数据，运用肠道微生物群相关基因富集分析(gene set enrichment analysis, GSEA)方法检测肠道微生物群和风湿病之间的关联。结果通过鉴定发现多个肠道微生物群均与三种风湿病相关(均有P＜0.05)。其中，瘤胃球菌属(Ruminococcaceae_UCG-009)与RA、SLE和AS均相关(均有P＜0.05)；Intestinibacter属和发酵性厌氧梭菌潜在新物种(Candidatus_Soleaferrea)则与RA和SLE相关(均有P＜0.05)。结论部分肠道微生物群可能通过其代谢物的作用成为新的风湿病调节因子，这为揭示肠道微生物群在风湿病中的作用提供了新的线索。

Abstract: Objective This study aims to detect the association between gut microbiota and rheumatoid arthritis (RA), systemic lupus erythematosus (SLE) and ankylosing spondylitis (AS). Methods The microbiota-related gene set enrichment analysis (GSEA) was applied to identify rheumatoid diseases-related gut microbiota using published genome-wide association study (GWAS) and GWAS of gut microbiota summary statistic data. Results Several associations between three rheumatoid diseases and gut microbiota were identified (all P < 0.05). Thereinto, Ruminococcaceae_UCG-009 was significantly associated with RA, SLE and AS (all P < 0.05). For RA and SLE, association signals were observed for Intestinibacter and Candidatus_Soleaferrea (all P < 0.05). Conclusion This study found that part of the gut microbiota could be novel regulators of rheumatoid diseases via the effects of its metabolites, and may provide novel clues for revealing the roles of gut microbiota in rheumatology.
