GA²LEN and EFA propose minimum specifications for all industrialised countries/regions to work towards to support students with food allergies in educational settings. We reviewed research and legislation and gained feedback from over 100 patient and professional groups. We built shared expectations around: 1. training all school staff about what f...
Hazelnuts are frequently involved in IgE-mediated reactions and are the main cause of nut allergies in Europe. Most food products are processed before human consumption. Food processing can modify the structure, properties, and function of proteins, and as a result, the IgE-binding capacity of allergens can be affected. In this study, we aimed to i...
This Anaphylaxis Manifesto calls on communities to prioritise 10 practical actions to improve the lives of people at risk of serious allergic reactions. The Global Allergy and Asthma European Network and the European Federation of Allergy and Airways Diseases Patients' Associations (EFA) compiled patient‐centric priorities. We used qualitative cons...
Background: Anaphylaxis is a systemic allergic reaction that is potentially life-threatening. Occupational anaphylaxis is an anaphylaxis that occurs in an occupational context. In this position paper, we propose diagnostic criteria for occupational anaphylaxis and provide an overview of the current state of knowledge in terms of prevalence, trigger...
Immunoglobulin E (IgE)‐mediated food allergies are the most common type of food allergy, often causing rapid symptoms after exposure to allergens posing a serious health risk and a high impact on patient's and caregiver's quality of life. Omalizumab, a humanized anti‐IgE monoclonal antibody, reduces allergic reactions by binding to circulating IgE....
This European Academy of Allergy and Clinical Immunology (EAACI) guideline provides recommendations for the management of IgE‐mediated food allergy and was developed using the Grading of Recommendations, Assessment, Development and Evaluations (GRADE) approach. Following the confirmation of IgE‐mediated food allergy diagnosis, allergen avoidance an...
Es gibt keinen Konsens über die Beschreibung und Schweregradeinteilung allergischer Nebenwirkungen bei Immuntherapien, obwohl zumindest hinsichtlich der Verwendung der Klassifikationssysteme der World Allergy Organisation (WAO) zur Beschreibung lokaler unerwünschter Ereignisse bei sublingualer Immuntherapie (SLIT) und systemischer allergischer Reak...
People who have suffered from anaphylaxis often experience far-reaching consequences in everyday life. Unfortunately, discharge management after successful acute treatment is often still inadequate. In order to prevent further reactions in the future and improve the patient’s quality of life, there are several points that should be addressed or fol...
Interdisciplinary medical treatment is required to care for patients with complex autoimmune diseases.

Anaphylaxis is an acute, potentially fatal, systemic hypersensitivity reaction that warrants prompt diagnosis and management. It continues to be challenging to anticipate who may be at risk of a severe, life-threatening allergic reaction. Anaphylaxis can be caused by a range of allergens, such as certain foods, medications, latex, insect stings, et...
Background
Children with sensitization against foods have to be orally food-challenged before eating these foods for the first time. However, the waiting time for an oral food challenge (OFC) in Germany is about 3–6 months. In contrast, there are hints that an early introduction of allergenic foods might be protective regarding the development of f...
