Occasionally, a seemingly straightforward history of food-induced anaphylaxis may prove to be misleading. Both patients and their physicians have a tendency to attribute the cause of an allergic reaction to the most conspicuous ingredient that had been ingested while overlooking less likely causes. Here, we describe a patient whose history pointed to oatmeal allergy, but skin prick tests to oats and serologic testing for oat-specific IgE were negative. Ultimately, we found that the oatmeal had been contaminated with an allergenic insect, Psocid of the order Psocoptera.
偶尔，看似简单的食物诱发过敏反应的病史可能会被证明是具有误导性的。患者及其医生都倾向于将过敏反应的原因归因于摄入的最明显的成分，而忽略了不太可能的原因。在这里，我们描述了一位患者，其病史提示对燕麦过敏，但对燕麦的皮肤点刺试验和针对燕麦特异性 IgE 的血清学检测均为阴性。最终，我们发现燕麦被一种具有过敏原性的昆虫——鳞翅目昆虫 Psocid 污染了。
