Prospective Survey of the Repeated Occurrence of Anaphylactic Reactions in Patients with Food Allergies
The goal of this observational study is to learn about repetitive anaphylactic reactions in food allergic patients and to compare the frequency of repetitive reactions between different elicitors in food allergic patients. The main question it aims to answer are: • Is there an elicitor specific difference in the occurrence of anaphylactic reactions once the elicitor has been identified and the patient received counselling about its avoidance? Participants will answer questionnaires via a link they will receive via e-mail at baseline and 3, 6, 12 and 24 months after inclusion in the study.
• anaphylactic reaction to peanuts, other legumes, tree nuts, seeds (e.g. sesame seed, sunflower seed), cereals (e.g. wheat, oat) or pseudocereals (e.g. quinoa)
• participation in the European Anaphylaxis Registry (Clinical Trials Identifier: NCT05210543)
• possibility and consent to receive links to the follow-up electronic surveys via e-mail and fill out the questionnaires electronically
