Weizenabhängige anstrengungsinduzierte Anaphylaxie

Abstract

Wheat-dependent exercise-induced anaphylaxis (WDEIA) is a rare IgE-dependent anaphylaxis to wheat, which occurs in sensitized people after ingestion of wheat followed by physical exercise. The major allergen associated with WDEIA is the wheat protein Omega (omega)-5-Gliadin (Tri a 19). We present three cases of WDEIA, demonstrating that this disease might be more frequent than anticipated and that neither prick test nor specific IgE to allergen extracts but rather detection of specific IgE against the recombinant protein Tri a 19 leads to diagnosis.
