Food-associated anaphylaxis. Data from the anaphylaxis registry

Severe allergic reactions are reported to the anaphylaxis registry in German-speaking countries. The data provides knowledge regarding the diagnosis and management of patients suffering from anaphylaxis. The ranking of the most frequent elicitors inducing anaphylaxis is age-dependent and also influenced by the group which is reporting the data. The list of food allergens inducing anaphylaxis also varies with age. In children and adolescents peanuts are common elicitors of food-dependent anaphylaxis: in adults wheat is the most frequent cause. Furthermore, the data from the anaphylaxis registry provides information about rare triggers, as well as alerting us to those causative agents which are increasing in frequency. The relevance of augmentation factors is most likely age-dependent, whereas co-morbidities including atopic diseases like atopic dermatitis and allergic asthma occur frequently in children suffering from food-dependent anaphylaxis. The present manuscript provides data on food allergens such as peas and cauliflower, which have been reported as rare causes of anaphylaxis.
