Egg Allergy

Protocols for Oral Immunotherapy (OIT) for the main food allergens have been recently incorporated in clinical practice for food allergies and their clinical benefits have been acknowledged in European and Canadian official guidelines. There has been some reluctance in both clinicians and patients to implement these therapies, primarily because of the risk of allergic reactions during the desensitization process. This study will investigate if protocols using low doses of a food allergen or processed versions of the allergen can be both effective in conferring desensitization while inducing fewer allergic symptoms during the desensitization process.

This study investigates the efficacy and safety of two different OIT schemes to treat milk and egg allergic children

The goal of this observational study is to learn about the long-term outcomes of children and young people who underwent an 18-month course of oral immunotherapy (OIT) treatment for peanut, egg or milk allergy. It aims to: • Compare long-term changes in health-related quality of life (HRQL) at 5-15 years after stopping OIT in participants who achieved remission and those who did not. Participants will attend a single follow-up visit for: * A blood test * Skin prick test (SPT) * Allergy questionnaires

Peanut allergy is the most common cause of fatal and near-fatal food-allergic reactions and egg allergy is among the two most common causes of food-induced anaphylaxis. The proposed research will explore the development of sensitization to these food(s) in infants based on maternal consumption or avoidance during pregnancy and breastfeeding.

Hen's Egg Allergy is one of the most common food allergies in early childhood. The first-line treatment is the elimination of hen's egg proteins from the child's or maternal diet. Available data from the literature indicate that most children with hen's egg allergy acquire tolerance to hen's egg proteins with age. An assessment of tolerance acquisition to them is commonly performed using egg ladder. However, scientific evidence regarding the effectiveness and safety of the egg ladder in children with hen's egg allergy is limited. Currently, there is no standardised egg ladder protocol, and different versions of the ladder and recommend by scientific societies in various countries. This study aims to assess the effectiveness and safety of the 4-step egg ladder (4-EL) compared to the 5-step egg ladder (5-EL) in children with IgE-mediated hen's egg allergy. This is an open-label, randomised superiority trial with two parallel arms and a 1:1 allocation ratio.

The aim of the study is to determine the efficacy of a 12-month egg oral immunotherapy (OIT) protocol with a cooked whole egg product including yolk and egg white. Study hypothesis: With this method the risk for severe allergic reaction to egg protein is reduced and the diet can partly or completely be normalized.
