Oral anaphylaxis due to food intake contaminated with mites (OMA, oral mite anaphylaxis) is an allergic reaction that can represent life risk for patients. There are reports of cases from different parts of the world and they involve mainly processed foods based on wheat flour contaminated with mites of several families of the Astigmatina cohort. However, it remains as a little known and difficult to diagnose syndrome. The objective of this study was to describe the first clinical case of OMA due to the consumption of oat flakes in Panama City, Panama.
Female patient of 39-years-old was entered an emergency room with allergic cutaneous and respiratory symptoms one hour after ingesting granola and oatmeal with milk at breakfast. After antiallergic treatment, the cause of allergy was determined by applying skin prick tests for ingested food and house mites. Results indicated a negative reaction for food and positive for mites. The mite analysis of the food samples directed in the identification of the species Blattisocius keegani and Suidasia pontifica, with a high density of the latter in flaked oats.
This work is the first worldwide report of anaphylaxis due to consumption of oats contaminated with mites.
因摄入被螨虫污染的食物而引发的口腔过敏反应（OMA，口腔螨虫过敏反应）是一种可能对患者生命构成威胁的过敏反应。世界各地均有相关病例报告，主要涉及以受粉螨科几个家族螨虫污染的小麦粉为原料的加工食品。然而，它仍然是一种鲜为人知且难以诊断的综合征。本研究的目的是描述在巴拿马城因食用燕麦片而引发OMA的首例临床病例。
一名39岁女性患者早餐食用了加牛奶的格兰诺拉麦片和燕麦片一小时后，因出现皮肤和呼吸道过敏症状被送入急诊室。经过抗过敏治疗后，通过对摄入食物和屋尘螨进行皮肤点刺试验确定了过敏原因。结果显示食物反应为阴性，螨虫反应为阳性。对食物样本进行的螨虫分析确定了种类为凯氏肉食螨和庞氏嗜木螨，后者在燕麦片中密度很高。
这项研究是全球首例关于食用被螨虫污染的燕麦引发过敏反应的报告。
