BACKGROUND AND OBJECTIVE: The gut microbiota, influenced by age and sex hormones, may correlate with the development and progression of benign prostatic hyperplasia (BPH). This study aims to characterize gut microbiota and metabolite profiles in BPH patients with varying prostate volumes.
METHODS: Fecal samples from BPH patients were analyzed using 16S rDNA sequencing and untargeted metabolomics. Microbial and metabolic differences were assessed via the Linear discriminant analysis Effect Size, KEGG pathway enrichment, and a mediation analysis.
KEY FINDINGS AND LIMITATIONS: We identified 26 differential amplicon sequence variants (ASVs) and 70 metabolites, with 18 microbes correlating significantly with clinical BPH indicators. The key pathways included unsaturated fatty acid and steroid hormone biosynthesis. Akkermansia (ASV549) may affect prostate volume through the regulation of intestinal amino acid metabolism and may negatively affect prostate-specific antigen levels by inhibiting heat shock protein (HSP) 90 (luminespib). Limitations include sample size and unmeasured confounders.
CONCLUSIONS AND CLINICAL IMPLICATIONS: Gut microbiota and metabolite diversity are associated with prostate volume; further studies are warranted to elucidate the potential interventions via microbiome modulation or metabolic targeting for BPH management.
PATIENT SUMMARY: In this study, we identified the potential associations between gut and both prostate volume and benign prostatic hyperplasia symptoms. These findings suggest that dietary interventions or fecal microbiota transplantation may represent potential strategies for modulating prostate health in the future.
