IgE-mediated food allergies in Swiss infants and children

摘要

Study question We aimed to determine the most frequent food allergens causing immediate food hypersensitivity reactions in Swiss children of different age groups. Summary answer The study found that eight allergens account for 83% of IgE-mediated food allergies in Swiss infants and children. The order of the most prevalent food allergens changes in relation to the patients' age: cow's milk is number one in the first 12 months of age, hen's egg in the second and third year, and peanut is the most prevalent above three years of age. What is known and what this paper adds The frequency and distribution of causative food allergens vary from country to country according to individual dietary practices. This study describes the most common food allergens involved in hypersensitivity reactions in children and demonstrates differences in the order of most common food allergens in three age groups.
