Celiac Disease: Not All Medications Are Contaminated with Gliadin…

IgA anti-gliadin antibodies in adult celiac disease.

We have improved the enzyme-linked immunosorbent assay for IgA-class antibodies to gliadin in serum by evaluating earlier publications. We also assess the value of measuring these antibodies when screening for adult celiac disease and monitoring dietary compliance. Of 61 adults with untreated celiac disease, 57 had abnormal results, giving a sensitivity for the test of 0.93. Patients (n = 283) ...

Determinants of gliadin-specific T cell selection in celiac disease.

In HLA-DQ8-associated celiac disease (CD), the pathogenic T cell response is directed toward an immunodominant α-gliadin-derived peptide (DQ8-glia-α1). However, our knowledge of TCR gene usage within the primary intestinal tissue of HLA-DQ8 (+) CD patients is limited. We identified two populations of HLA-DQ8-glia-α1 tetramer(+) CD4(+) T cells that were essentially undetectable in biopsy samples...

Deaminated Gliadin Peptide Antibody in the Diagnosis of Celiac Disease

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...

Non-celiac gluten sensitivity: All wheat attack is not celiac

Currently, 1% of the United States population holds a diagnosis for celiac disease (CD), however, a more recently recognized and possibly related condition, "non-celiac gluten sensitivity" (NCGS) has been suggested to affect up to 6% of the United States public. While reliable clinical tests for CD exist, diagnosing individuals affected by NCGS is still complicated by the lack of reliable bioma...
