ABSTRACT
Background:
Previous observational studies have shown that there is an important relationship between gut microbiota and hypertension, we performed a two-sample Mendelian randomization analysis to examine whether the gut microbiota is causally related to hypertension in order to find a basis for potential diagnostic or intervention approaches for hypertension.Methods:
We obtained significant single nucleotide polymorphisms related to gut microbiota and hypertension from publicly available genome-wide association studies for a two-sample Mendelian randomization study. A total of 18,340 individual genome-wide genotype data were included from 24 population-based cohorts. The inverse-variance weighted meta-analysis is the main analytical method for evaluating causal relationships, and the Mendelian randomization research results have been validated through a series of sensitivity analyses.Results:
The inverse-variance weighted analysis results indicated that phylum Verrucomicrobia (OR0.831, 95%CI 0.710-0.972; p = 0.021), family BacteroidalesS24.7group (OR0.672, 95%CI 0.496-0.911; p = 0.01), family Bifidobacteriaceae (OR0.709, 95%CI0.569-0.884, p = 0.002), genus Adlercreutzia (OR 0.991, 95%CI 0.982-0.999, p = 0.035), genus Phascolarctacterium (OR0.819, 95%CI0.685-0.981; p = 0.03), genus LachnospiraceaeNK4A136group (OR0.990, 95%CI0.981-0.999; p = 0.025), and genus Ruminococcus2 (OR0.988, 95%CI 0.979-0.997; p = 0.008) had protective causal effects on hypertension. The Family Alcaliginaceae (OR1.011, 95%CI1.000-1.021, p = 0.04), Genus Anaerostipes (OR1.375, 95%CI1.096-1.653; p = 0.025), Genus Collinsella (OR1.899, 95%CI1.361-2.348; p = 0.02), and Genus Lachnospiraceae_UCG_010 (OR1.536, 95%CI1.072-2.202; p = 0.019) were associated with a higher risk of HTN. The reverse Mendelian randomization analysis results showed no reverse causal relationship between HTN and these bacterial taxa.Conclusion:
Our Mendelian randomization analysis results indicate a potential causal relationship between these bacterial taxa and hypertension, providing a new perspective for the treatment and prevention of hypertension.
