摘要:
目的:探讨肠道菌群(GM)对青光眼、原发性开角型青光眼(POAG)和原发性闭角型青光眼(PACG)的因果关系。方法:采用孟德尔随机化分析方法,利用GM相关GWAS数据(18,340例)、青光眼相关GWAS数据(18,902例及358,375对照)、POAG相关GWAS数据(7756例及358,375对照)和PACG相关GWAS数据(1199例及358,375对照)确定GM对青光眼的因果效应。结果以比值比(OR)和95%置信区间(CI)表示。结果:MR分析结果显示,genus LachnospiraceaeUCG010 (IVW, OR = 1.20, 95% CI [1.06, 1.35], P = 0.0029)、genus Ruminiclostridium9 (IVW, OR = 1.26, 95% CI [1.08, 1.46], P = 0.0026)和genus Streptococcus (IVW, OR = 1.17, 95% CI [1.05, 1.30], P = 0.0053)与青光眼风险显著增加有因果关系,而family Oxalobacteraceae (IVW, OR = 0.88, 95% CI [0.80, 0.97], P = 0.0077)与青光眼风险显著降低有因果关系。phylum Actinobacteria与POAG风险显著增加有因果关系。Class Erysipelotrichia、order Erysipelotrichales、family Erysipelotrichaceae、genus Anaerotruncus与PACG风险显着增加有因果关系。结论:我们的研究从不同分类水平的GM进一步证实了GM对青光眼的因果效应,以及GM对POAG和PACG的相对特异性。然而,需要进一步的研究来证实这些结论。Purpose: To verify the causal effects of gut microbiota (GM) on glaucoma, primary open-angle glaucoma (POAG) and primary angle-closure glaucoma (PACG). Methods: Mendelian randomization analysis was conducted to identify the causal effect of GM on glaucoma via using GM-related GWAS data (18,340 samples), glaucoma-related GWAS data (18,902 cases and 358,375 controls), POAG-related GWAS data (7756 cases and 358,375 controls) and PACG-related GWAS data (1199 cases and 358,375 controls). The outcome was expressed as odds ratio (OR) with 95% confidence intervals (CI). Results: The MR analysis results presented that genus LachnospiraceaeUCG010 (IVW, OR = 1.20, 95% CI [1.06, 1.35], P = 0.0029), genus Ruminiclostridium9 (IVW, OR = 1.26, 95% CI [1.08, 1.46], P = 0.0026) and genus Streptococcus (IVW, OR = 1.17, 95% CI [1.05, 1.30], P = 0.0053) were causally associated with a significantly increased risk of glaucoma, while family Oxalobacteraceae (IVW, OR = 0.88, 95% CI [0.80, 0.97], P = 0.0077) were causally associated with a significantly decreased risk of glaucoma. Phylum Actinobacteria was causally associated with a significantly increased risk of POAG. Class Erysipelotrichia, order Erysipelotrichales,
