Description

Case 1 was a 39-year-old woman and Case 2 was a 57-year-old man. Both patients had histories of hay fever or allergic rhinitis, but not of atopic dermatitis, food allergy, or an oral allergy syndrome. Neither had previously experienced allergy to a soybean product, but both had allergic symptoms after drinking soy milk. A CAP-RAST analysis was negative for soybean, but positive for Glym4, alder, and birch. Skin prick tests were positive for soymilk. Both cases were diagnosed as a soymilk class 2 food allergy on the basis of cross-reactivity between pollen antigen and a class 2 food antigen. We explained to the patients that they could consume tofu, soybean products, soybean oil, and fermented foods like bean paste and fermented soybeans, but that they must not consume soymilk, soymilk skin, or tofu containing a high level of moisture.
