Increased Detection of Celiac Disease With Measurement of Deamidated Gliadin Peptide Antibody Before Endoscopy

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...

Deaminated Gliadin Peptide Antibody in the Diagnosis of Celiac Disease

Diagnostic utility of deamidated gliadin peptide antibody in celiac disease compared to anti-tissue transglutaminase and IgA- endomysium antibodies.

Deamidated gliadin peptide antibodies have recently been suggested as reliable tools for celiac disease (CD) diagnosis. We compared their utility for diagnosis CD in comparison to the routinely used anti-endomysial, and anti-tissue transglutaminase antibodies. We studied 65 patients (17 men, 48 women; age range, 17- 63 years) who underwent intestinal biopsy because of clinical suspicion of smal...

Antibodies to deamidated gliadin peptide in diagnosis of celiac disease in children.

OBJECTIVES Determination of antibodies to synthetic deamidated gliadin peptides (anti-DGPs) may work as an alternative or complement the commonly used test for tissue transglutaminase antibodies (TGA) in the diagnosis of celiac disease (CD). We analyzed the performance of a time-resolved immunofluorometric anti-DGP assay (TR-IFMA) in the diagnosis of CD in children and also retrospectively anal...

Celiac disease: antibody recognition against native and selectively deamidated gliadin peptides.

BACKGROUND Selective deamidation of glutamine residues by tissue transglutaminase (tTG) turns gliadin peptides into stronger activators of T cells from celiac disease (CD) patients. We examined the possibility that these modified peptides could be more specific epitopes for circulating antibodies than are native peptides. METHODS Two native synthetic peptides and their respective modified seq...
