title: [Anaphylaxis to PR-10 proteins (Bet v1 homologues)].
abstract: Secondary food allergies to PR-10 proteins (Bet v1 homologues) are the most common food allergies in Germany. Clinically they present with an oral allergy syndrome (intraoral pruritus and perhaps swelling). When drinks containing PR-10 proteins are rapidly consumed, for example after sporting activities, large concentrations of allergen can be reached without any intraoral symptoms and then lead to anaphylaxis. This phenomenon has often been described for soja milk and occurred in our case with an apple drink with 60% fruit concentration. It seems likely that such cases of anaphylaxis are not adequately represented in the anaphylaxis registry.
