Evaluation of allergy to soy in patients with atopic dermatitis older than 14 years of age

Atopic dermatitis is associated with food allergies. The aim of this study is to evaluate soy allergy in patients suffering from atopic dermatitis. Altogether 228 persons were included; specific IgE, skin prick tests, atopy patch tests, challenge tests with soy and history of soy allergy were evaluated. Soy allergy was confirmed in eight patients (3.5%, in four patients with worsening of atopic dermatitis, in four patients with oral allergy syndrome), sensitisation to soy was found in another 47 patients (20%) with no clinical manifestation after soy ingestion. Dependence was confirmed statistically between soy allergy and pollen allergy and soy sensitivity and pollen allergy. About 20% of patients suffering from atopic dermatitis are sensitised to soy. Clinical symptoms of soy allergy occur only in 3.5% of patients suffering from atopic dermatitis.
