    Abstract:
    Inflammatory Bowel Diseases are a group of diseases with chronic inflammation of the gastrointestinal tract, but without proven etiology. Immunologic, environmental, infective and genetic factors equally can play role in their development. Antibodies to an oligomannose epitope of the Saccharomyces cerevisiae demonstrated in 60-70% of the patients with Crohn's disease. The origin and the clinicopathological role are not clarified. It is important that there are no surveys with patients suffering in gluten sensitive enteropathy in the literature. As there are no ASCA survey in Hungary, the aim of this study was to determine the prevalence of the ASCA. The authors examined at their patients the ASCA's occurrence and compared with the clinical picture of the Crohn's disease. The results supported the theory that ASCA positivity correlates with small intestines' Crohn's disease and in these cases both the IgG and IgA type antibodies proved. The antibodies in the sera at the analyzed ASCA positive cases prove a systemic immune response against Saccharomyces cerevisiae and the authors suggest the end of the oral tolerance against the yeast's antigens. The diet restriction (elemental diet, total parenteral nutrition, and fecal diversion) may ameliorate the status of the patients with Crohn's disease. It is speculated that the yeast-free diet as a part of the therapy for the ASCA positive patients can be reasonable: moreover the permanent "forbidding" of the yeast can be an acceptable alternative in case of getting well.
