We investigated the presence of IgA anti-tissue transglutaminase (tTG) antibodies in untreated coeliac disease (CD) and other gastrointestinal diseases, and compared IgA tTG concentrations with anti-endomysium (EMA) immunofluorescent findings. The study included 116 untreated CD patients (74 female, 42 male, age range 15-78 years, median 47 years), 82 treated CD patients, 65 patients with normal duodenal histology, 260 disease control samples and 29 healthy volunteers. IgA anti-tTG, EMA, and anti-gliadin (ACA) antibodies were measured. Serum total IgA was measured in the CD patients. Two IgA-deficient untreated CD patients were excluded. IgA EMA and IgA AGA were positive in 99 69 (61%), respectively, of the 114 untreated CD patients. Elevated IgA anti-tTG were found in 92/114 (81%) untreated coeliacs, 1/82 (1%) treated coeliacs, 2/65 (3%) non-coeliacs, 10/260 (4%) disease controls and 2/29 (7%) volunteers. Four of the untreated CD patients, with a normal serum total IgA concentration, were negative for all the serological tests. IgA anti-tTG concentrations were significantly higher in untreated coeliacs (median 10 200 units/ml) than in other groups (Mann-Whitney, p
