Basophil Activation Test to Diagnose Food Allergy
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...
Basophile Activation Testing (BAT) in Hazelnut Allergy (Hazelnut BAT Study)
The proposed study intends to compare the outcome of food challenge in hazelnut allergic patients with the outcome of basophile activation tests using hazelnut extract and components.
Behandling af Boern Med Foedevareallergi Med Omalizumab (Xolair)
Food allergy is a common disease in childhood affecting up to 8% of children in Westernized countries. About 30 percent of children with food allergies are allergic to more than one food, most often milk, egg, wheat, peanut and tree nut. Peanut and hazelnut are common triggers of severe and potentially fatal food-induced anaphylactic reactions. Currently, there is no curative treatment for food allergy. Novel therapies for this potentially life-threatening condition are therefore much needed.
Benralizumab for Eosinophilic Gastritis
A Randomized, Double-Blind, Placebo-Controlled Clinical Trial to Evaluate the Efficacy of Benralizumab (Anti-IL5RA) in Subjects With Eosinophilic Gastritis.
Blood Samples for the Study of Peanut, Tree Nut and Other Food Allergies
Food allergies are now a major problem. These experiments involve getting blood from people with food allergies and from people without food allergies. The blood collected will be used to answer questions and find information about peanut and other food allergies. Samples will come from: - People signed up by the investigators at the University of Colorado Denver - University of North Carolina and Massachusetts General Hospital where people have been treated for peanut allergies - University of North Carolina, Massachusetts General Hospital, National Jewish Health and The Children's Hospital in Denver where...
Boiled Peanut Immunotherapy for the Treatment of Peanut Allergy
Peanut allergy is the most common cause of severe allergic reactions to food. Onset is common in childhood, but in contrast to other food allergies such as cow's milk and egg, peanut allergy tends to persist into adulthood. It is associated with a significant impact on quality of life, both for the affected individual and their family. There is no current cure for peanut allergy. Oral peanut immunotherapy (OIT) using defatted, roasted peanut flour has been demonstrated to offer potential in this regard, but is associated with significant and frequent reactions and can cause life-threatening allergic symptoms. The investigators have...
Boiled Peanut Oral Immunotherapy
Prospective Phase 1 clinical trial providing proof of concept data on boiled peanut oral immunotherapy (OIT) for the treatment of peanut allergy in children. The investigators hypothesize that the proportion of subjects successfully desensitized with boiled peanut OIT is greater than the theoretical placebo rate of 20%.
Boiled Peanut Oral Immunotherapy for the Treatment of Peanut Allergy: a Pilot Study
Peanut allergy is increasingly common, especially in countries such as UK and Australia. There is currently no accepted routine clinical therapy to cure peanut allergy. Recently studies have looked at desensitising people with peanut allergy by giving them small daily doses of roasted peanut. Although this therapy works for some people, its effects are not generally long lasting and it is associated with many side effects during protocol, resulting in a significant rate of drop-outs. Pilot data suggests that boiled peanut is less immunogenic than roasted peanut, and may therefore provide a safer way of inducing desensitisation in patients...
Breast Milk: Influence of the Micro-transcriptome Profile on Atopy in Children and Toddlers
This is an observational cohort study of 200 breast-feeding mother-infant dyads delivered at term. The goal of the study is to investigate whether levels of immune-related microRNAs (miRNAs) in maternal breast milk (MBM) influence child atopy risk in the first 12 months, defined as atopic dermatitis, wheezing, or food allergy. Infant exposure to individual miRNA components will be quantified at 0, 4, and 16-weeks after delivery using high throughput RNA sequencing of MBM samples and detailed dietary logs employing the Infant Feeding Practices (IFP) survey. The relationship of individual miRNA exposures (parts per million) and ...
Can Vitamin D Supplementation in Infants Prevent Food Allergy in the First Year of Life? The VITALITY Trial
There is an urgent need to prevent the onset and progression of food allergy in our population. Evidence demonstrates that food allergy and atopic eczema represent the earliest manifestations of the atopic march with 50% of infants with food allergy predicted to develop respiratory allergic diseases later in life. We report that Australia has the highest prevalence of IgE-mediated food allergy in the world, with 10% of infants having challenge-proven food allergy in Melbourne. There has been a 5-fold increase in hospital admissions for life-threatening anaphylaxis. These changes are most pronounced in children less than 5 years, suggesting...
