OBJECTIVE To determine the extent of celiac autoimmunity in type 1 diabetic patients and the overlap between islet and celiac autoimmunity in their nondiabetic relatives. RESEARCH DESIGN AND METHODS IgA antibodies to tissue transglutaminase were determined in serum taken from 433 type 1 diabetic patients and 1,442 nondiabetic first-degree relatives. Samples with transglutaminase antibodies ab...

Celiac disease has been associated with other autoimmune disorders such as autoimmune hepatitis, moreover it is known that T cell mediated immune response to dietary gluten and released cytokines are important for the entheropathy seen in celiac disease. We investigated celiac autoantibodies in patients with autoimmune hepatitis (AIH), and chronic hepatitis B (CHB).Sera from 84 patients with Au...

Background: Celiac disease is a common autoimmune disorder that is diagnosed based on clinical case identification, serological screening, and duodenal histology. However, the existence of mild clinical forms, such as seronegative cases with patchy atrophy and potential celiac disease, can make it difficult to determine a definitive diagnosis. The seronegative patients with celiac disease can i...

Gluten sensitivity typically presents as celiac disease, a common chronic small intestinal disorder. However, in certain individuals it is associated with dermatitis herpetiformis, a blistering skin disease characterized by granular IgA deposits in the papillary dermis. While tissue transglutaminase has been implicated as the major autoantigen of gluten sensitive disease, there has been no expl...

BACKGROUND Celiac disease (CD) occurs in as many as 1 in 80 pregnant women and is associated with poor pregnancy outcome, but it is not known if this is an effect on maternal nutrient absorption or, alternatively, if the placenta is an autoimmune target. The major autoantigen, tissue transglutaminase (tTG), has previously been shown to be present in the maternal-facing syncytiotrophoblast plasm...

BACKGROUND/AIMS Celiac disease has a large prevalence worldwide. There are a limited number of comparable epidemiological data for celiac disease in Turkey. The aim of this preliminary study was to determine the prevalence of celiac disease in a sample of 1000 Turkish children by a novel, simple, and visual one-step immunoassay screening test. METHODS This prospective study consisted of 1000 ...

Recently, anti-deamidated gliadin antibodies were proposed for the serological diagnosis of celiac disease. We evaluate the specificity of different anti-deamidated gliadin antibodies ELISA in comparison with conventional anti-native gliadin kits. Serum samples from 46 non celiac patients were analyzed by five different quantitative ELISA for anti-native gliadin, anti-deamidated gliadin and ant...

BACKGROUND/AIMS The use of immunoglobulin G and A anti-gliadin antibodies for celiac disease screening has decreased due to higher specificity and sensitivity of tissue transglutaminase and endomysial antibodies. Greater values of immunoglobulin-A anti-gliadin antibody have been associated with more severe mucosal damage in proven and probable celiac disease patients. The aim of this study was ...
