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.
Biomarkers in Food Allergy Diagnosis
Food allergy is a global burden, affecting patients, society as a whole and the economy. For most common food allergies, patients synthesize specific IgE-antibodies against harmless food proteins. Clinical phenotypes of food-allergic patients are highly diverse. Differences in medical symptoms (organs, severity, delay), threshold and cross-reactivity levels suggest variable underlying endotypes. The aim of this study is to identify phenotypic biomarkers for advanced stratification of food-allergic patients. Our study will consist of up to 50 participants (30 food-allergic, 20 tolerant), recruited in Luxembourg. Clinical samples...
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...
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...
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...
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 ...
Canadian Peanut Thresholds Study
An important gap in the management of peanut allergy is that we do not know the threshold dose, below which most peanut allergic individuals will not react. There is likely a spectrum of reactivity to peanut where some individuals react to trace doses, whereas others are able to tolerate larger doses. The purpose of this study is to determine the minimum threshold dose needed to cause a mild objective reaction when peanuts are consumed by peanut-allergic individuals in a carefully controlled clinical setting. 30 peanut-allergic participants aged 7-65 years will undergo a two-day, double blind placebo controlled food challenge. ...
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,...
Cause of Unexplained Anaphylaxis
This study will explore the possible cause of unexplained, or idiopathic, anaphylaxis. Anaphylaxis is a rapid, life-threatening, severe reaction that occurs suddenly after contact with an allergy-causing substance, usually a particular food, drug or stinging insect. The allergen triggers mast cells to release several substances, including histamine. Histamine is responsible for many of the symptoms that may occur, such as flushing, hives, swelling of the palms and soles or tongue and vocal cords, nasal congestion, itching and tearing of the eyes, shortness of breath and wheezing, stomach pain, vomiting, low blood pressure, loss of ...
