Cow's Milk Elimination for Treatment of Eosinophilic Esophagitis
The investigators seek to assess the efficacy of removing cow's milk from an EoE patient's diet. This will be determined by esophageal inflammation and clinical and histological response to the milk elimination treatment.
Defining ENDOtypes in Perioperative Hypersensitivity by Extensive Cellular and Molecular PHENotyping (ENDOPHEN)
Perioperative Acute Hypersensitivity (PAH) is a systemic reaction that occurs rapidly following injection of a drug during anesthesia.The HSA-PA reaction must occur within a maximum of one hour after the induction of anesthesia or a new product by the anesthetist. The main mechanism evoked is an immune response of immediate systemic hypersensitivity or anaphylaxis. Anaphylactic reactions are classically described as IgE-dependent and triggered by the injection of allergen which by bridging specific IgE present on the surface of mast cells, induces a massive release of histamine responsible for the observed symptoms. The diagnosis of...
Detection of Metabolite Biomarkers for the Early Diagnosis and Prognosis of Cow's Milk Allergy in Children
In this study, fecal and urine samples will be collected from children diagnosed with : - IgE mediated cow's milk allergy, - suspected of a cow's milk allergy, but with negative diagnosis - IgE mediated food allergy other than cow's milk - healthy brothers and sisters of the first three groups A subset of patients with IgE-mediated cow's milk allergy will be asked to provide a urine and fecal sample yearly for prognostic purposes. The samples will be analyzed using a technique called metabolomics to identify biomarker candidates with diagnostic and/or prognostic potential. Additionally,...
Effect of Personalized Elimination Diet on Food Sensitivity Related Symptoms
The goal is to identify food sensitivity in patients and assess whether the avoidance of the reaction-inducing foods via an 'elimination diet' leads to improvement in patient symptoms and overall well-being.
Efficacy and Safety of Benralizumab in Patients With Eosinophilic Gastritis and/or Gastroenteritis (The HUDSON GI Study)
This is a 3-part study. Part A is randomized, double-blinded, placebo-controlled and includes patients with eosinophilic gastritis and/or duodenal-only disease. After completing Part A, participants can continue to Part C - open-label benralizumab treatment period. Following the decision to close enrollment, patients in both Part A and Part C will be given the option to proceed to 6-months of open-label benralizumab treatment in Part D.
Efficacy of Low-Dose Topical Steroids in Maintaining Remission of Eosinophilic Esophagitis in Children
This study evaluates the decrease in steroid dosing for patients who have achieved remission on a full dose of steroids. Once a patient is in remission they will be enrolled in this study if they choose to decrease the steroid dosing.
Egg Allergy Oral Desensitization
This study evaluates whether tolerance to eggs can be induced in patients through a process of oral immunotherapy. Participants will be randomized into groups receiving oral immunotherapy and a control group that will receive no intervention
Evaluation of Medical Care and Patient's Knowledge About the Behavior to Take on Secondary Prevention of Anaphylaxis
Anaphylaxis is a hypersensitivity reaction systemic, generalized, severe, life-threatening that may result from exposure to a triggering factor. The prevalence of anaphylaxis is 0.05 to 2% in the general population. Most reactions appear within 30 minutes after contact with the triggering factor and last up to 6 hours. The main triggering factors are: 1/food, 2/hymenopteran bites, 3/drugs. The main treatment is the early administration of adrenaline by Intramuscular route on medical prescription or by AAI (adrenaline auto-injector) associated with the exclusion of the allergen. Adrenaline treatment should be administered as soon as...
Gradual Egg-tolerance Induction in Hen's Egg Allergic Children
1. The investigators here want to test the hypothesis that a total period of 18 months of gradual open introduction of a certain egg product with regard to full egg tolerance induction is not inferior when compared to a total period of 30 months gradual open introduction of a certain egg product (see steps for the specific egg products) after tolerance for baked egg has been obtained. 2. The investigators also want to define step-specific 'tolerance-failures' and study the relevance of specific IgE to specific egg components to predict failures at each step.
Grass Pollen Immunotherapy Plus Dupilumab for Tolerance Induction
The primary objective of this study is to assess whether the combination of grass allergen sublingual immunotherapy (SLIT) and dupilumab for 2 years is more effective than double placebo in suppressing the nasal allergen challenge (NAC) response to grass pollen at 1 year after completion of study medication.
