    Abstract:
    In coeliac patients the age of development of symptoms, clinical picture of the disease and complications depend on the dose of ingested gluten. The aim of the study was the evaluation of individual sensitivity to small doses of gluten in the group of 60 patients aged 2.65 to 17.92 (mean age 7.49) treated with gluten-free diet for at least 12 months due to coeliac disease diagnosed according to ESPGAN criteria (food allergy to gluten excluded). Gluten challenge with dose of 10 mg/kg body mass/day was controlled with serological tests (IgAEmA, IgAAGA, and IgGAGA antibodies) carried out every 3 to 6 months. Jejunal biopsy was performed before gluten challenge (normal mucosa), and after positive EmA/AGA antibodies tests to confirm diagnosis (flat mucosa). After 35 months of observation 53.7% of all patients presented of jejunal villious atrophy, and positive IgAEmA. In this group 3.7% presented symptoms after 3 months of gluten challenge, 5.5% after 6 months, 3.7% after 9 months, and 3.7% after 12 months. In some coeliac patients ingestion of small amounts of gluten (10 mg/kg/day) can lead to small intestinal villious atrophy.
