Brief Summary:
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).

Detailed Description:
The gut microbiota contributes to the health of the host. It enables the digestion of food, the proper functioning of the immune system, and protection against the invasion of pathogens. The gut microorganisms play a key role in maintaining the integrity of the intestinal epithelium. The epithelium serves as a selective barrier that, on the one hand, separates the immune cells of the intestinal mucosa from the microorganisms present in the lumen of the gut, and at the same time allows microbial metabolites to interact with the host cells and thus regulate the immune response. Dysbiosis of the intestinal microflora may result in damage to the intestinal integrity and, consequently, an increase in the permeability of the intestinal barrier. The translocation of bacterial antigens and metabolites into the bloodstream contributes to the activation of the local and systemic immune response resulting in local and systemic inflammation. Disruption of the interaction between the gut microbiome and the host can lead to inflammation. Plaque psoriasis is a chronic, immune-mediated dermatitis. It is manifested by peeling, itching, and reddening of the skin. Psoriasis is a non-communicable disease 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. The etiology of psoriasis development is not fully understood. In addition to genetic predisposition, the increased immune response in PS may be a consequence of systemic inflammation due to intestinal dysbiosis associated with increased intestinal permeability.
Dietary ingredients support skin health. Among them, prebiotics gained our special interest as ingredients with proven beneficial effects on host health by modulating gut microflora. Inulin-type fructans derived from chicory are prebiotics that favorably alters the composition and activity of the intestinal microbes and alleviates the inflammation in the intestines. The investigators supposed that restoring the balance of the gut microbiota 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 aim of the research is to determine whether dietary supplementation with inulin-type β-fructans derived from chicory will transfer health benefits to individuals with psoriasis and to investigate whether these benefits are due to modification of the composition or activity of the gut microbiota.
To achieve this goal, the original, advanced, and complex studies were proposed on subjects with psoriasis to investigate the effects of dietary inulin-type fructans on the characteristics of the gut microflora, metabolic parameters, and biomarkers of the skin-gut axis. The obtained results will provide new knowledge and explain the nature of the interaction between the gut microbiota and the skin, providing further clues about the functioning of the gut-skin axis.
