ABSTRACT
BACKGROUND:
The nasal cavity and gut are interconnected, both housing a rich natural microbiome. Gut microbiota may interact with nasal microbiota and contribute to the development of chronic rhinosinusitis (CRS). However, the specific role of gut microbiota in CRS has not been fully investigated. Therefore, we conducted a two-sample Mendelian randomization study to reveal the potential genetic causal effect of gut microbiota on CRS.METHODS:
We performed a two-sample Mendelian Randomization (MR) analysis using aggregated data from genome-wide association studies (GWAS) on gut microbiota and CRS. The primary method used to assess the causal relationship between gut microbiota and CRS was the inverse variance weighting (IVW) method. In addition, sensitivity analyses were conducted to evaluate the robustness of the MR results, including heterogeneity, pleiotropy, and leave-one-out tests.RESULTS:
Genetically predicted twelve gut microbiota, including class Coriobacteriia, class Methanobacteria, family Coriobacteriaceae, family Methanobacteriaceae, family Pasteurellaceae, genus Haemophilus, genus Ruminococcus torques group, genus Subdoligranulum, order Coriobacteriales, order Methanobacteriales, order Pasteurellales, and phylum Proteobacteria, demonstrated a potential inhibitory effect on CRS risk (P < 0.05). In addition, four gut microbiota, including family Streptococcaceae, genus Clostridium innocuum group, genus Oscillospira, and genus Ruminococcaceae NK4A214 group, exhibited a causal role in increasing CRS risk (P < 0.05). Sensitivity analyses showed no evidence of heterogeneity or pleiotropy (P > 0.05).CONCLUSIONS:
This study reveals the causal relationship between specific gut microbiota and CRS, which provides a new direction and theoretical foundation for the future development of interventions and prevention and treatment strategies for CRS.Key words
