Celiac sprue is a chronic, lifelong disease characterized by permanent intolerance to gluten. Small intestinal mucosa of these patients shows typical inflammatory changes. These changes lead to reduced absorption of nutrients, minerals and vitamins that may result malabsorption syndrome. Diagnosis of celiac disease must be a comprehensive evaluation of the results of immunological testing of autoantibodies and microscopic evaluation of the intestinal mucosa state. The bachelor thesis deals with the histochemical examination of intestinal biopsies, which allows better distinguish malabsorption syndromes of different origin. The aim of the study was to determine incidence of celiac sprue and evaluate the completeness of remission in patients on a gluten - free diet in patients aged over 50 years in intestinal biopsies samples taken in 2013. Strict gluten - free diet leads to reparation of mucosa and brush border enzyme activity. Biopsies were snap frozen immediately after collection, to preserve the morphology of tissue and the brush border enzyme activity. Reactions, demonstrating the enzymatic activity of the lactase, trehalase and dipeptidylpeptidase IV, were exercided on sections by previously described histochemical methods. Alteration of relief was assessed by Marsh score. In 2013 was recieved... |
