Positive skin reactions to gluten in coeliac disease.
Following intradermal challenge with a peptic-tryptic digest of gluten, visible Arthus-type skin reactions were observed in 33 per cent of a group of 55 adults with coeliac disease. Of the 23 with untreated disease positive skin reactions occurred in 52 per cent. There was an invariable association between serum gluten antibodies and the presence of a skin reaction to gluten, indicating that gluten antibody combination with gluten in the skin provides the basis of the skin response. Since no false positive reactions were found in 52 normal controls, skin testing with gluten may provide a useful adjunct to the diagnosis and management of coeliac disease, especially in the outpatient department.
