Anaphylaxis to food typically occurs after ingestion [1,
2] ; however, it can also occur after skin contact with vomited
food such as egg and milk [27] , or inhalation of minute
food particles; for example, sleeping on pillows stuffed
with soy products can cause nocturnal anaphylaxis in
soy-sensitized patients [28] .
In wheat-dependent exercise-induced anaphylaxis,
IgE antibodies to recombinant omega 5 -gliadin are detectable
in more than 80% of patients. In their absence, it can
be helpful to determine IgE reactivity to other wheat proteins
such as α-β-γ-gliadin (especially γ-gliadin) and high
molecular weight glutenin
