INulin-type Fructans-induced Gut Microbiota Modulation Impact on GUT-SKIN Axis Parameters in Psoriasis

Rövid összefoglaló (regiszter, angolul)

There is increasing evidence of a strong, bidirectional correlation between the gut and the skin, that associates gastrointestinal health with skin homeostasis and allostasis. The dysregulation in the intestinal microbiome-host interplay is connected with the development of many chronic skin inflammations. Plaque psoriasis is a chronic, immune-mediated non-communicable dermatitis affecting approximately 2-3% of the world's population, regardless of gender and age. In most cases (about 70-80%), the skin lesions are mild and do not require systemic treatment. Its etiology is not fully understood, but apart from the genetic predisposition, it is strongly associated with the "gut-skin axis". The rise of the local and systemic immune response in psoriasis is a consequence of systemic inflammation due to intestinal dysbiosis associated with increased intestinal permeability. Thus, gut microbiota modulation should become a research target due to its great potential to impact inflammation, including skin dermatitis, and its manifested consequences. Diet is an underestimated element in psoriasis management, meanwhile, the dietary ingredients support skin health. Among them, prebiotics favorably alters the composition and activity of the intestinal microbes and alleviates inflammation in the intestines. It was hypothesized that restoring the balance of the gut microbiome and the proper functioning of the intestinal barrier in subjects with psoriasis will alleviate the inflammatory symptoms and skin lesions observed in this chronic dermatitis. The goal of this clinical trial is to determine if a diet supplementation with prebiotic (chicory-derived inulin-type β-fructans; ITFs) vs. placebo (maltodextrin) will induce health-related benefits in a mild degree PS, and determine if the identified benefits are evoked by compositional and/or functional shifts of the intestinal bacterial communities. Healthy individuals will constitute a control group (C).
