Evaluation of the INOVA diagnostics enzyme-linked immunosorbent assay kits for measuring serum immunoglobulin G (IgG) and IgA to deamidated gliadin peptides.

چکیده
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 conventional gliadin antibodies, 54 (96%) were negative for DGP antibodies.

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 کاملSimultaneous 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...

AIM To determine the diagnostic accuracy of a new point-of-care assay detecting anti-deamidated gliadin peptides in celiac disease (CD) patients. METHODS One-hundred-and-twelve patients (age range: 1.8-79.2 years old) with clinical symptoms suggestive of CD and/or first-degree relatives (FDR) of CD patients (n = 66), and confirmed CD on a gluten-free diet (GFD) (n = 46), were prospectively en...

Coeliac disease is an inflammatory disease of the small intestine caused by ingestion of wheat gluten or related proteins from rye or barley. In the small intestine, ingested gluten is broken down into gliadin peptides which are deamidated by the enzyme tissue transglutaminase (tTg) resulting in the substitution of glutamine amino acid residues with glutamic acid. These modified gliadin peptide...
