Gluten immunochemistry to react with gamma gliadin to a degree comparable to DQ2.5. T-cell responses to the high molecular weight glutenin may be more important with DQ8 mediated than DQ2.5 mediated celiac disease. Antibody recognition of gluten is complex. Direct binding to gluten such as anti-gliadin antibodies has an ambiguous pathogenesis in coeliac disease. The crosslinking of gliadin with tissue transglutaminase leads to the production of anti-transglutaminase antibodies, but this is mediated through T-cell recognition of gliadin. The allergic recognition of gliadin by mast cells, eosinophiles in the presence of IgE has notable direct consequences, such as exercise-induced anaphylaxis. Anti-gliadin antibodies, like
Wheat allergy cause. If symptoms are alleviated by immunosuppressant drugs, such as Prednisone, an allergy-related cause is likely. If multiple symptoms associated with wheat allergies are present in the absence of immunosuppressants then a wheat allergy is probable. Management of wheat allergy consists of complete withdrawal of any food containing wheat and other gluten-containing cereals (gluten-free diet). Nevertheless, some patients can tolerate barley, rye or oats. In people suffering less severe forms of wheat-dependent exercise induced anaphylaxis (WDEIA), may be enough completely avoiding wheat consumption before exercise and other cofactors that trigger disease symptoms, such as nonsteroidal anti-inflammatory drugs and alcohol.
