Negative results of antiendomysial antibodies: long term follow up.

Fifteen patients with intestinal villous atrophy, but simultaneously negative results of antiendomysial antibodies (EMA) were studied. Two patients were finally diagnosed as having coeliac disease. The predictive value of negative results of EMA assessment in children suspected of coeliac disease is high, approaching 86.7%.

Transmission electron microscopy of microvilli of intestinal epithelial cells in celiac disease in remission and transient gluten enteropathy in children after a gluten-free diet.

The structure of microvilli of intestinal epithelial cells was investigated in 70 children: 34 with celiac disease in remission, 28 with transient gluten enteropathy after a gluten-free diet, and eight controls. Transmission electron microscopy was used to determine the mean thickness of the glycocalyx layer covering the microvilli, the mean length and width of microvilli, and the number of microvilli per 1 micron length of enterocyte surface. The structure of the glycocalyx was found to be intact, but in some children with treated celiac disease the layer of glycocalyx was either thin or absent on the surface of individual cell microvilli. In children with treated celiac disease, microvilli were statistically significantly shorter than those in children with transient gluten enteropathy and controls. Microvillous width in treated celiac disease was greater as compared with that in controls. There was no difference in the number of microvilli on the enterocyte surface in the three groups.

[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.
