Although Japanese radish (Raphanus sativus L.) is a common Japanese ingredient, there are few reports of IgE-mediated immediate food allergy caused by Japanese radish.
A 48-year-old woman developed urticarial lesions on her hands after grating Japanese radish and also developed lip edema and oral itching when she ate a salad composed of raw Japanese radishes. Skin prick testing was positive to extract of grated Japanese radish. Moreover, immunoblotting analysis showed IgE reactivity in the patient's serum to a single band at the 18 kDa in grated Japanese radish, suggesting that the heat-labile 18 kDa protein of raw Japanese radish may be a radish-specific antigen.
To the best of our knowledge, this is the first case report of a patient with hand urticaria, lip angioedema, and oropharyngeal pruritus to raw Japanese radish through IgE-mediated immediate allergic reaction.
虽然日本萝卜(萝卜属萝卜种)是日本常见的食材,但由日本萝卜引起的IgE介导的速发型食物过敏报道较少。
一名48岁女性在磨碎日本萝卜后手部出现荨麻疹皮损,食用由生日本萝卜组成的沙拉时还出现唇部水肿和口腔瘙痒。皮肤点刺试验对磨碎的日本萝卜提取物呈阳性。此外,免疫印迹分析显示患者血清中IgE与磨碎的日本萝卜中18 kDa处的单一条带发生反应,提示生日本萝卜中热不稳定的18 kDa蛋白可能是萝卜特异性抗原。
据我们所知,这是首例通过IgE介导的速发型过敏反应,出现手部荨麻疹、唇部血管性水肿和口咽瘙痒的生日本萝卜过敏患者的病例报告。
