Celiac disease is a common severe intestinal disease resulting from intolerance to dietary wheat gluten and related proteins. The large majority of patients expresses the HLA-DQ2 and/or DQ8 molecules, and gluten-specific HLA-DQ-restricted T cells have been found at the site of the lesion in the gut. The nature of peptides that are recognized by such T cells, however, has been unclear so far. We...

Recent studies have shown a worldwide prevalence of coeliac disease (CD) of around 1% and one of the highest prevalence rates (1 in 300) has been found in the West of Ireland. 1,2 The incidence of coeliac disease appears to be increasing. For example, a greater than 6-fold increase over a 20 year period was evident in a recent retrospective Scottish study. 3 Children with selective IgA deficien...

OBJECTIVES To analyse frequency of HLA class II antigens (DR and DQ) and lymphocytotoxic autoantibodies in patients with systemic lupus erythematosus (SLE) and subsets with or without neuropsychiatric involvement. METHODS Ninety three patients with SLE (42 with neuropsychiatric features) were typed for HLA class II antigens and investigated for the presence of lymphocytotoxic autoantibodies b...

There is an error in the first sentence under the subheading Study Subject, in the Materials and Methods section. The correct sentence is: A 27 year-old woman (HLA A1, B8, B72, DR8, DR17, DQ2, and DQ4) was the recipient of a right hand from a male donor article distributed under the terms of the Creative Commons Attribution License, which permits unrestricted use, distribution, and reproduction...

1. the most important challenge in diagnosis of celiac disease is not-performing the diagnostic tests in suspected persons. because of multi-organ damage and multiple manifestations of disease, diagnosis of celiac disease may be delayed. it seems general physicians should be aware about uncommon presentations of disease and indications of celiac tests. 2. the second most important challenge is ...

OBJECTIVE Diagnostic criteria for coeliac disease (CD) from the European Society for Paediatric Gastroenterology, Hepatology, and Nutrition (ESPGHAN) were published in 1990. Since then, the autoantigen in CD, tissue transglutaminase, has been identified; the perception of CD has changed from that of a rather uncommon enteropathy to a common multiorgan disease strongly dependent on the haplotype...

BACKGROUND AND AIM the essential genetic marker related with celiac disease (CD) is the HLA-DQ2 molecule encoded by the DQA1*0501 and DQB1*0201 genes. The aim of this study is to evaluate effect of these alleles on the clinical, serological and histological features of Turkish children with celiac disease. MATERIAL AND METHODS we divided 36 celiac patients to 4 groups according to their HLA-D...

An association has recently been described between increased birth weight and increased risk of childhood-onset type 1 diabetes. Whether this relationship is explained by genes associated with both increased birth weight and increased risk of type 1 diabetes is unknown. In the present study, we tested the association between birth weight and HLA-DQ genotypes known to confer risk for type 1 diab...

Celiac disease is an immune-mediated enteropathy triggered by the ingestion of gluten-containing grains (including wheat, rye, and barley) in genetically susceptible persons. The disease is associated with HLA-DQ2 in 90 to 95 percent of cases and with HLA-DQ8 in 5 to 10 percent of cases and is self-perpetuating in the continued presence of gluten. 1 It is the interplay between genes (both HLA a...
