The food supplement bee pollen has been previously found to cause anaphylactic reactions. It has been proposed as useful for "everything from bronchitis to hemorrhoids."
This study describes an atopic patient who experienced a non-life-threatening anaphylactic reaction upon her initial ingestion of bee pollen. Microscopic examination of the pollen sample and ELISA inhibition assays were performed.
The patient had a 7 mm/28 mm wheal/erythema reaction to bee pollen at 1 mg/mL concentration. Bee pollen caused 52% inhibition of IgE binding to short ragweed and 55% to ryegrass. Microscopic analysis revealed ragweed, Alternaria, Cladosporium, honeysuckle (Lonicera sp), privet shrub (Ligustrum sp), and vetch (Vicia sativa).
An unknowingly sensitized atopic patient experienced an anaphylactic reaction after ingestion of a small quantity of bee pollen that contained pollens and fungi. Previously administered allergen immunotherapy that had reduced rhinitis symptoms did not prevent this allergic reaction.
先前已发现食品补充剂蜂花粉会引起过敏反应。有人提出它对“从支气管炎到痔疮的各种疾病”都有用。
本研究描述了一名特应性患者，她在首次摄入蜂花粉后经历了一次非危及生命的过敏反应。对花粉样本进行了显微镜检查和酶联免疫吸附测定抑制试验。
患者对浓度为1mg/mL的蜂花粉出现了7mm/28mm的风团/红斑反应。蜂花粉对短豚草的IgE结合有52%的抑制作用，对黑麦草有55%的抑制作用。显微镜分析显示有豚草、链格孢属、枝孢属、金银花（忍冬属）、女贞（女贞属）和野豌豆（野豌豆）。
一名不知情已致敏的特应性患者在摄入含有花粉和真菌的少量蜂花粉后发生了过敏反应。先前进行的已减轻鼻炎症状的变应原免疫疗法未能预防此次过敏反应。
