Anti-gliadin antibodies were one of the first serological markers for coeliac disease. Problematic with AGA is the typical sensitivity and specificity was about 85%. Gliadin peptides which are synthesized as the deamidated form have much higher sensitivity and specificity, creating 2 serological tests for CD that approach biopsy diagnostic in ...
Anti-gliadin IgA antibodies are found also more commonly in patients with IgA Nephropathy. The paper finds a link between GSE and IgA Nephropathy, but not between CD and nephropathy. [103] Calcium oxalate correlates with severity of fat malabsorption in coeliac disease. [104] [105]
Anti-gliadin antibodies, like those detected in coeliac disease bind to the α-2 gliadin (57–73). [36] This site is within the T-cell reactive "33mer" presented by DQ2.5. There has been some suggestion wheat plays a role in juvenile diabetes as antibodies to the non-glutinous seed storage glb-1 (a globulin) are implicated in crossreactive ...
Anti-α-gliadin antibodies are frequently found in celiac disease (CD), to a lesser degree subclinical CD, but are also found in a subset who do not have the disease. Of people with pseudo-exfoliation syndrome , 25% showed increased levels of anti-gliadin IgA. [ 49 ]
If all these antibodies are negative, then anti-DGP antibodies (antibodies against deamidated gliadin peptides) should be determined. IgG class anti-DGP antibodies may be useful in people with IgA deficiency. In children younger than two years, anti-DGP antibodies perform better than anti-endomysial and anti-transglutaminase antibodies tests. [8]

Reported symptoms of NCGS are similar to those of celiac disease, [30] [31] with most patients reporting both gastrointestinal and non-gastrointestinal symptoms. [29] [32] In the "classical" presentation of NCGS, gastrointestinal symptoms are similar to those of irritable bowel syndrome, and are also not distinguishable from those of wheat allergy, but there is a different interval between ...
A well studied model is celiac disease, in which increased intestinal permeability appears secondary to the abnormal immune reaction induced by gluten and allows fragments of gliadin protein to get past the intestinal epithelium, triggering an immune response at the intestinal submucosa level that leads to diverse gastrointestinal or extra ...
