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.
小麦依赖运动诱发的过敏反应(WDEIA)是一种罕见的对小麦的IgE依赖型过敏反应,发生在致敏个体摄入小麦后再进行体育锻炼时。与WDEIA相关的主要过敏原是小麦蛋白ω-5-醇溶蛋白(Tri a 19)。我们报告了3例WDEIA病例,表明这种疾病可能比预期的更为常见,并且针刺试验和针对过敏原提取物的特异性IgE均不能诊断该病,而检测针对重组蛋白Tri a 19的特异性IgE才能确诊。
