“… 20 Wheat has been reported as the most common food trigger of anaphylaxis in China and the most common trigger for food-dependent exercise-induced anaphylaxis (FDEIA). 3 , 21 , 22 Studies in Japan, 23 , 24 Korea, 25 and Europe 6 have reported similar results. It may partly be because of the high consumption, and high processing of wheat products, which results in a higher level of gluten and immunogenic epitopes.…”

“…It has been reported worldwide and most commonly affects adolescents and young adults with a prevalence of approximately 0.02% although the exact number might probably be higher due to underdiagnosis [ 1 ]. It has a slight male predominance (55%) with the median age at onset of 21 years (range 4–82 years) [ 5 , 6 ]. Contrary to its term, not all patients diagnosed with FDEIA present with anaphylaxis.…”

“…Contrary to its term, not all patients diagnosed with FDEIA present with anaphylaxis. According to the recent meta-analysis of 722 patients, 3 different phenotypes were identified including anaphylaxis with wheals and/or angioedema (80%), wheals, angioedema, or both without anaphylaxis (17%), and anaphylaxis without wheals or angioedema (4%) [ 5 ]. However, the clinical significance of differentiating the phenotype for FDEIA remains to be further explored.…”

“…The alternative explanation is that orally ingested glycoprotein forms of alpha-gal, which clearly can be allergenic in vitro and in vivo when introduced parenterally, are absorbed, processed and presented to IgE-bound mast cells with a delay of 3-5 h. 37 This is clearly different from classic IgE-mediated food allergy, such as peanut allergy, but has parallels with some forms of wheat allergy, where co-factors are important and there is often a substantial delay between ingestion and symptom onset. 133 Whether the relevant source of alpha-gal is in glycolipid and/or glycoprotein form, there is now good in vivo evidence that peak levels of alpha-gal require two or more hours to reach the systemic circulation after challenge with a mammalian meal. 134 The recent development of models of semi-humanized pigs (i.e.…”
