Food allergies pose serious health risks, including life-threatening anaphylactic reactions, increased morbidity, and reduced quality of life. Wheat allergy is a common concern in Asia. There is growing interest in understanding the potential association between dysregulation of the gut microbiome and the development of food allergies.
Cutaneous manifestations of chronic spontaneous urticaria (CSU) are identical to type 1 hypersensitivity reactions. The daily occurrence of rash from occupational allergy could be misinterpreted as CSU exacerbation.
Acute urticaria is a common cutaneous disease encountered in children, while anaphylaxis can show cutaneous symptoms as well as systemic symptoms. One study found that urticaria tends to precede anaphylaxis, but studies on the different role of eosinophils and related cytokines in anaphylaxis and urticaria are lacking.
