Simultaneous Detection of IgA/IgG AntiTissue Transglutaminase/Deamidated Gliadin Peptides in Serodiagnosis of Celiac Disease
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...
متن کامل[Anti-deamidated gliadin peptides antibodies and coeliac disease: state of art and analysis of false-positive results from five assays].
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...
متن کاملThe Diagnostic Value of Serum IgG-Antigliadin, IgA Anti-endomysial and IgA Anti-tissue Transglutaminase Antibodies for Pediatric Celiac Disease
Background and Objective: Celiac disease is an autoimmune disorder, characterized by inflammation, villous atrophy, and crypt hyperplasia of the small bowel mucosa. In this study we considered and compared sensitivity and specificity of serological tests in patients with celiac disease. Materials and Methods: In this cross-sectional study we prospectively recruited children with suspected c...
متن کاملNatural history of antibodies to deamidated gliadin peptides and transglutaminase in early childhood celiac disease.
INTRODUCTION Gliadin proteins play a key role in the pathogenesis of celiac disease; however, as a screen for celiac disease, anti-gliadin antibody testing has been replaced by the more sensitive and specific serological assays for transglutaminase autoantibodies (TGAA). A new generation of anti-gliadin antibody assays has been developed to detect synthetic, deamidated homologous gliadin peptid...
متن کاملMarkers of gluten sensitivity and celiac disease in bipolar disorder.
OBJECTIVES Increased immune sensitivity to dietary gluten proteins has been reported in schizophrenia but has not been studied in bipolar disorder. In this study, we examine the levels of antibody reactivity to gliadin, deamidated gliadin, and tissue transglutaminase (tTG) in individuals with bipolar disorder and compare these levels to those in individuals who do not have any history of psychi...
