- Background: Previously, a gluten challenge was customary to establish the diagnosis of celiac disease in children. There are no clear recommendations on how to perform this challenge or what markers to rely on for timing the biopsy after the challenge. The authors' aim was to monitor gluten intake, clinical symptoms, and antibody kinetics to evaluate the influence of gluten exposure during the challenge.Methods: Twenty-five children under investigation for suspected celiac disease were challenged. One child was excluded because blood samples, food records, or biopsy was lacking. Median age at the postchallenge biopsy was 3.8 (2.7-8.8) years. The families kept daily records of the children's gluten intake and of symptoms that occurred. Blood samples were taken monthly for analysis of antigliadin and endomysium antibodies and total immunoglobulin A (IgA). A third biopsy was performed when clinical symptoms suggested a relapse.Results: All 24 children showed deterioration of the mucosa or elevated antibodies during gluten challenge. Median duration of the challenge was 13 (5-51) weeks, and mean gluten intake was 1.7 (0.2-4.3) g/d and 0.1 (0.02-0.26) g/kg daily.Conclusions: Gluten intake during the challenge varied widely, and the parents were unable to give their children the recommended amount. Despite the small amounts given, all children showed signs of relapse at a clinical, laboratory, or histologic level. Much smaller amounts of gluten than previously suggested seem sufficient to cause relapse during gluten challenge in children.
