Filter by:The goal of this study is to test the safety and feasibility of a change in management approach for infants with newly diagnosed egg allergy. Infants with newly diagnosed egg allergy will have egg introduced via a gradual and graded home based approach known as an "egg ladder" supervised by a dietitian. The main questions this study aims to answer are how safe and feasible are home-based dietitian-led "egg ladders" as a treatment pathway to achieve tolerance of egg for newly diagnosed infants with egg allergy.
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.
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.
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.
The BAT Impact study is a prospective multicentre study in the UK using a biomarker-led study design to compare the incidence of adverse events (defined as allergic reactions during oral food challenges) in a randomized-controlled trial. Patients will either follow the standard-of-care (i.e. an oral food challenge in case of equivocal SPT/sIgE) or follow a basophil activation test (BAT)/mast cell activation test (MAT)-based strategy, i.e. patients with a positive BAT or MAT are dispensed of an oral food challenge (OFC) and patients with a negative BAT/MAT undergo an OFC.
The investigators would only include the children who received propofol (Propolipid, Fresenius Kabi, Schelle, Belgium) for sedation, the investigators would exclude the children that didn't receive propofol during the procedure. The investigators would analyze the incidence of hypersensitivity reaction to propofol in children allergic to egg, soy or both egg and soy and to compare those with the incidence of hypersensitivity reactions in children without allergy to egg and/or to soy. Those data were retrieved following longitudinal follow-up after the intervention. Allergy tests by skin and radioallergosorbent tests were performed in all children before the gastrointestinal endoscopy under anesthesia took place, but no results were known at the time of the sedation. A patient was defined as allergic to egg and/or soy if the patient had specific S-IgE level more than the normal level set by our institution (0.35 kU/L). The investigators would also investigate the influence of other obtained parameters in the dataset (age, ASA score, weight category, type of investigation, respiratory and neurological comorbidities, respiratory infections, GERD, other allergies) on those results with multivariate analysis. We considered that clinical features suggesting a hypersensitivity reaction present during anaesthesia were cutaneous, respiratory or cardiovascular manifestations. Depending on the severity of the reaction, necessitating prompt hemodynamic resuscitation with the administration of epinephrine, antihistamines, inhaled beta-agonists or corticosteroids.
The investigators want to test the hypothesis that a total period of 12 months of stepwise open egg introduction is not inferior when compared to a total period of 20 months gradual open egg introduction of a certain egg product with regard to full egg tolerance induction.
To determine the efficacy and safety of AR201 in a characterized oral desensitization immunotherapy (CODIT™) regimen in hen egg-allergic subjects aged 4 to 26 years, inclusive.
The aim is to analyse the results of per oral immunotherapy treatment in severe milk, peanut or egg allergy in adults. This is the second part of the oral immunotherapy study in adults at Skin and Allergy Hospital. The diagnosis of food allergy is verified with positive history, skin prick tests, egg and milk allergen specific IgE (immunoglobulin E) antibodies. In addition, food allergy is verified with an open label (milk allergy) or blind (peanut and egg allergy) allergen specific challenge test. OIT (oral immunotherapy) is performed according to a detailed plan. Lung function parameters are followed before OIT and and a year after OIT.
The BAT II Study is a cross-sectional diagnostic study in which children with suspected IgE-mediated allergy to foods (namely cow's milk, egg, sesame and cashew), as defined by a history of an immediate-type allergic reaction to a food or no history of food consumption or the presence of food-specific IgE as documented by skin prick test or serum specific IgE, will undergo a diagnostic work-up to confirm or refute the diagnosis of IgE-mediated food allergy. Participants will be prospectively recruited from specialised Paediatric Allergy clinics in London and will undergo skin prick testing (SPT), specific IgE testing to allergen extracts and allergen components, basophil activation test (BAT) and oral food challenge. The diagnostic accuracy of the BAT and of other allergy tests will be assessed against the clinical gold-standard.
