Gajdárová, Zuzana

Inflammatory bowel diseases (IBD) are an autoimmune illnesses affecting gastrointestinal tract. The main types include ulcerative colitis and Crohn's disease. Recently, primary sclerosing cholangitis (PSC) has also been associated with IBD. PSC is a chronic liver disease associated with bile duct stenosis. The exact pathogenesis and etiology of these diseases is not clear, despite the great efforts of the scientific community. They are multifactorial diseases that are associated with dysbiosis of intestinal microbiota. Their diagnosis is based on for patients unpleasant endoscopic examinations and therefore the search for new serum biomarkers is needed and appreciated target of scientific interest. In the first part of diploma thesis, we focused on the reactivity of peripheral blood cells of IBD patients to 10 selected representatives of typical intestinal microbiota: Lactobacillus plantarum, Bifidobacterium adolescentis, Blautia coccoides, Roseburia intestinalis, Eubacterium rectale, Faecalibacterium prausnitzii, Ruminococcus flavefaciens, Bacteroides thetaiotaomicron, Prevotella ruminicola and Escherichia coli. Reactivity of CD, UC and PSC- IBD patients was increased after stimulation with Faecalibacterium, Lactobacillus and Prevotella. However, we got low percentage of cytokine-producing cells,...
