- Among bacterial species with higher abundance in the psoriasis gut microbiome, Bacteroides vulgatus and Parasutterella excrementihominis have been associated with other immune-mediated diseases.
- Increased intestinal colonization of Bacteroides vulgatus and elevated Bacteroides vulgatus reactive serum antibodies have been reported in ulcerative colitis patients.
- Moreover, colonization of Bacteroides vulgatus is sufficient to promote colitis in several animal models, which further supports the active role of Bacteroides vulgatus in development of colitis.
- The abundance of Akkermansia muciniphila was significantly reduced in patients with psoriasis .
- A. muciniphila is believed to have an important function in the pathogenesis of IBD and obesity; therefore, A. muciniphila, which is an indicator of health status, may be a key node for psoriasis as well as IBD and obesity. (1)
- Altered gut barrier in psoriasis is associated with gastrointestinal symptoms, systemic inflammatory profile and the increased blood concentration of gut microbiota-derived metabolite – TMAO.
- Biologic therapy may have an impact on the composition of the gut microbiome of psoriatic patients.
- The psoriatic subject showed a decrease in Firmicutes abundance and an increase in Proteobacteria abundance.
- An increase in Streptococcaceae, Rhodobacteraceae, Campylobacteraceae and Moraxellaceae has been observed in psoriatic subject.
