Abstract

OBJECTIVE: Barley and rye are major components of the Western diet, and historic feeding studies indicate that they cause clinical effects in patients with coeliac disease (CD). This toxicity has been attributed to sequence homology with immunogenic wheat sequences, but in adults with CD, these cereals stimulate unique T cells, indicating a critical contribution to gluten immunity independent of wheat. Clinical and immune feeding studies with these grains in children with CD are sparse. We undertook a barley and rye feeding study to characterise the clinical and T-cell responses in children with CD. DESIGN: 42 children with human leucocyte antigen (HLA)-DQ2.5+ (aged 3-17 years) consumed barl..
