Antigliadin antibodies have been widely used in the screening of celiac disease. Using this test, candidates for jejunal biopsy were selected from 328 first-degree relatives of 128 adult celiac patients. All relatives geographically available were willing to participate in the study. Twenty-one turned out to be positive for antigliadin antibodies, and in 13 jejunal histology was consistent with celiac disease. In the remaining 8, the morphometric evaluation of jejunal biopsy specimens showed a mean surface to volume ratio that, although in the normal range, was significantly lower than that of other 10 relatives negative for antigliadin antibodies and 16 biopsied controls. It was concluded that antigliadin antibody testing is a valuable method for the screening of celiac disease among family members and that relatives with genetically predisposed gliadin sensitivity, without gross histological lesions but with minor morphometric abnormalities of the jejunal mucosa, may be regarded as subjects with latent celiac disease

Abstract
Antigliadin antibodies have been widely used in the screening of celiac disease. Using this test, candidates for jejunal biopsy were selected from 328 first-degree relatives of 128 adult celiac patients. All relatives geographically available were willing to participate in the study. Twenty-one turned out to be positive for antigliadin antibodies, and in 13 jejunal histology was consistent with celiac disease. In the remaining 8, the morphometric evaluation of jejunal biopsy specimens showed a mean surface to volume ratio that, although in the normal range, was significantly lower than that of other 10 relatives negative for antigliadin antibodies and 16 biopsied controls. It was concluded that antigliadin antibody testing is a valuable method for the screening of celiac disease among family members and that relatives with genetically predisposed gliadin sensitivity, without gross histological lesions but with minor morphometric abnormalities of the jejunal mucosa, may be regarded as subjects with latent celiac disease
