An altered gut microbiota is observed in inflammatory bowel disease (IBD), and maintaining and modulating the gut microbiome through prebiotics, probiotics, and synbiotics may have beneficial effects on health and potential therapeutic effects in IBD. Pre, Pro, and Syn consumption led to reductions in plasma IL-6 levels, increased intestinal occludin expression, modulation of gut microbiota, improved gut integrity, upregulation of anti-inflammatory cytokines, and suppression of pro-inflammatory mediators, suggesting their potential in treating IBD.
In inflammatory bowel disease (IBD), an altered gut microbiota is observed and is a proposed causal factor for compromised intestinal integrity and disease progression. Therefore, maintenance and modulation of the gut microbiome may be beneficial to health and for treatment of IBD. Prebiotics, probiotics, and synbiotics have been suggested to positively impact the gut microbiota and thus we aimed to evaluate the effects of a formulated prebiotic mixture (Pre), probiotic mixture (Pro), and synbiotics (Syn) in normal mice, and their therapeutic effects in acute dextran sulfate sodium (DSS)-induced mice. We observed significant reductions in plasma IL-6 levels and increased intestinal occludin expression in both models after treatment. In DSS-induced mice, treatment modulated gut microbiota, improved gut integrity, upregulated anti-inflammatory cytokines, and suppressed plasma pro-inflammatory mediators, potentially via inhibition of IL-6/STAT3 signaling. Our results demonstrate the beneficial effects of Pre, Pro, and Syn consumption and their potential therapeutic effects in IBD.
