Coeliac disease: always something to discover.

The authors present more than 20 years' experience with coeliac disease, with a summary of their published studies. Hair shaft characteristics were determined by scanning electron microscopy. Hair diameter was significantly lower and cuticular erosion scores higher in those who were not on gluten-free diets as compared to controls, showing a tendency towards normal values following start of gluten-free diets. Proton-induced X-ray emission showed significantly lower zinc content of the hair shaft in the group with acute coeliac disease and after a short-term diet, which approached the normal range only after a year-long diet. The serum prolactin levels in healthy controls and in coeliac patients on the diet were within normal limits, whereas in children with coeliac disease taking gluten in their meals, a significant hyperprolactinaemia was found. The erythrocyte glutathione content of coeliac children was elevated, and the glutathione disulfide level was significantly decreased, as compared to values in n...
