New assays for antibodies to deamidated gliadin peptides (DGP) expressing celiac disease-specific epitopes were evaluated using 154 sera previously tested for endomysial immunoglobulin A (IgA) (EMA), transglutaminase IgA (TGA), and conventional gliadin antibodies. DGP antibody results showed 97% concordance with EMA and TGA results. Of 56 sera negative for EMA and TGA but positive for conventio...

Background: IgA class serum autoantibodies against type 2 (tissue) transglutaminase (TG2) bind to both intestinal and extraintestinal normal tissue sections in vitro, eliciting endomysial, reticulin, and jejunal antibody reactions. It is not known whether similar binding also occurs in coeliac patients in vivo, and may thereby contribute to disease manifestations. Aims: To investigate intestina...

BACKGROUND Wheat, rye, and barley proteins induce celiac disease, an autoimmune type of gastrointestinal disorder, in genetically susceptible persons. Because the disease may be underdiagnosed, we estimated the prevalence of the disease and tested the hypothesis that assays for serum autoantibodies can be used to detect untreated celiac disease and that positive findings correlate with specific...

OBJECTIVES To study myopathies with serum antibodies to the signal recognition particle (SRP), an unusual, myositis specific antibody associated syndrome that has not been well characterised pathologically. METHODS Clinical, laboratory, and myopathological features were evaluated in seven consecutive patients with a myopathy and serum anti-SRP antibodies, identified over three years. The anti...

IgA nephropathy is the most common form of primary glomerulonephritis worldwide. Mucosal infections and food antigens, including wheat gluten, have been proposed as potential contributing environmental factors. Increased immune reactivity to gluten and/or association with celiac disease, an autoimmune disorder triggered by ingestion of gluten, have been reported in IgA nephropathy. However, stu...

BACKGROUND In some studies inflammatory bowel disease (IBD) and celiac disease were considered to be associated and some belive that this association may influence the prognosis of IBD. However, there is a cosiderable controversy regarding this association. Therefore ,we aimed to assess the association of these two common digestive diseases and evaluate the complications of this association. ME...

OBJECTIVE The purpose of this study was to explore whether the presence of thyroid and endomysial autoantibodies at diagnosis of type 1 diabetes in children predicts development of thyroid and celiac disease, respectively, and whether diabetes-associated autoantibodies at diagnosis predict development of microvascular complications up to 13 years later. RESEARCH DESIGN AND METHODS Autoantibod...

Background. Celiac disease (CD) is more prevalent among type 1 diabetes (T1D) patients compared to the general population and can be accompanied by hypoglycemia episodes in T1D patients. Studies worldwide have reported CD prevalence with large variability. This study aimed estimate pooled of Methods. PubMed, Web Science, Science Direct, Scopus were searched without time limitation using keyword...

background: vitiligo is an acquired, idiopathic disorder characterized by circumscribed depigmented macules and patches. the exact etiology and pathogenesis of vitiligo is not clear. many theories have been presented regarding this subject among them aautoimmune theory is the most important one. the association of vitiligo with other autoimmune disorders has been reported, but the relationship ...
