[Morphologic appearance of intestinal microvilli in children with coeliac disease and secondary malabsorption syndromes after gluten-free diet and gluten challenge].

: The glycocalyx and the structure of the microvilli were analysed in electron microscopy in 122 children with coeliac disease and secondary syndromes of malabsorption. Slight differences were noted in glycolayx structure between both groups of children. In children with coeliac disease its reduction was noted (after gluten challenge). Changes were observed also in the structure of the microvilli. They were lower and often with abnormal shape in coeliac disease, while they were high and of normal structure in secondary malabsorption syndromes.
