Allergy to white potato has rarely been described. We report two cases of atopic patients, housewives, in whom peeling raw potatoes precipitated rhinoconjunctivitis and asthmatic attacks, and, in one of them, contact urticaria. Type I hypersensitivity to raw potato antigens was demonstrated by means of immediate skin test reactivity, specific IgE determination by RAST, basophil degranulation, histamine release test and an immediate bronchial provocation test response to raw potato extract. The controls did not react to any of these tests. Potato allergenic constituent is currently being investigated but, as far as we know, it is heat-labile and has an MW of more than 10 Kd.
对白土豆过敏的情况鲜有报道。我们报告了两例特应性患者，均为家庭主妇，她们在削生土豆皮时会引发鼻结膜炎和哮喘发作，其中一人还出现了接触性荨麻疹。通过即时皮肤试验反应性、用放射性变应原吸附试验（RAST）测定特异性IgE、嗜碱性粒细胞脱颗粒、组胺释放试验以及对生土豆提取物的即时支气管激发试验反应，证实了对生土豆抗原的I型超敏反应。对照组对这些试验均无反应。目前正在研究土豆的致敏成分，但据我们所知，它对热不稳定，分子量超过10千道尔顿。
