    Abstract:
    The diagnostic value of gliadin antibody determination using the fluorescent immunosorbent test was examined in a prospective multicenter study comprising 251 children with malabsorptive disorders. Antibodies to gliadin were found in all 72 patients (100%) with active celiac disease (29 children with celiac disease proved by challenge, 43 with probable celiac disease). All children up to the age of 7 years had antibodies in high titers. By contrast, 96 (84%) of 114 children with other malabsorptive disorders and a normal mucosa or with partial villous atrophy had no gliadin antibodies, 14 (12%) had a low titer, and only four (3.5%) showed moderate to high titers. Four children with gastrointestinal tract symptoms of cow milk intolerance and a flat mucosa also showed no antibodies. In 24 of 29 children (83%) with cystic fibrosis and six of seven children with Crohn disease (biopsies not performed in either group), no antibodies could be detected. The others had low or elevated titers. In 25 children with acute gastroenteritis (not biopsied) antibodies were not found at hospital admission nor six weeks later after reintroduction of gluten. The determination of antibodies to gliadin with the fluorescent immunosorbent test is a reliable screening test for childhood celiac disease. In our series there were no false negative results in children with untreated celiac disease. A positive gliadin antibody titer is not proof of celiac disease. In each child the diagnosis must be confirmed by small intestinal biopsy even if the gliadin antibody titer is high. The detection of high titers of cow milk antibodies in 27% of patients with celiac disease is of no value.
