Abstract

Abstract : The gut microbiome has been increasingly suggested as an underlying cause of various human diseases. In this study, we hypothesized that the gut microbiomes of patients with familial adenomatous polyposis (FAP) are different from those of healthy people and attempted to identify the associations between gut microbiome characteristics and FAP. We collected fecal samples from patients with FAP and healthy volunteers and evaluated the diversity, composition, and distribution of the gut microbiome between the 2 groups via 16S rRNA-based taxonomic profiling of the fecal samples. Fecal samples were collected from 10 patients with FAP (4 men and 6 women, mean age 39.2 ± 13.8 years) and 10 healthy volunteers (4 men and 6 women, mean age 40.9 ± 9.8 years). The microbial richness in patients with FAP was significantly lower than that in healthy people. Regarding microbial composition, the Firmicutes/Bacteroidetes ratio in patients with FAP was higher than that in healthy people, especially in those with a lower proportion of Bacteroidetes and a higher proportion of Proteobacteria. We also found 7 specific abundant strains in fecal samples of patients with FAP. Patients with FAP had different Firmicutes/Bacteroidetes ratios and Proteobacteria abundance compared to healthy people and showed the presence of specific bacteria. These findings suggest a promising role of the gut microbiome in patients with FAP, although further studies are needed.
