DEpth of EPinephrine Delivery With Auto-injectors Devices
Anaphylaxis is a serious allergic reaction that is rapid in onset and may cause death. Although there are several causes of fatal anaphylaxis, food allergy is one of the most common. Epinephrine is recommended as the initial treatment of choice for anaphylaxis. A delay in epinephrine administration may contribute to an increased risk of death. Therefore, the World Allergy Organization recommends that, for the treatment of anaphylaxis, epinephrine solution be administered intramuscularly in the mid-anterolateral thigh. In France 3 auto-injector pens are available: Anapen®, Epipen® and Jext®. For weight> 30 kg, the devices have a needle size...
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, microbiome analysis ...
Determine Immunoglobulin G4 (IgG4) Standards for Cow's Milk and Egg in Different Populations of Allergic and Non-allergic Children
The study objectives are : Determine standards of plasma levels of casein-specific immunoglobulin G4 (IgG4) and egg-specific immunoglobulin G4 (IgG4) as a function of age, in non-allergic children, in allergic children, and in cured former allergic patients. Analyze the plasma IgG4 / IgE ratio, according to the result of the oral provocation test (tolerance versus allergy) and, in the event of a reaction, according to the reactogenic dose (dose which caused the reaction).Determine whether analysis of the plasma metabolome can identify children with a cured allergy to cow's milk protein or to egg from those with a persistent...
Diagnosis of Cow's Milk Protein Allergy
The study will assess the diagnosis of cow's milk protein allergy (CMPA) among infant and children in assiut university children hospital using skin prick test and specific serum IgE as well as their management.
Diagnostic Accuracy and Safety of DBV1605 for the Diagnosis of Non-IgE Mediated Cow's Milk Allergy in Children
Study to assess the diagnostic accuracy (sensitivity, specificity, positive and negative predictive value) of DBV1605 for the diagnosis of non-Immunoglobulin E (IgE) mediated cow's milk allergy (CMA) in children with symptoms suggestive of non-IgE mediated CMA.
Diagnostic Equivalence of the Skin Prick Test Tape vs. Conventional Skin PrickTest
Testing of a new ready-to-use Tape in comparison to the currently used skin prick test for the diagnosis of allergies. Assessment of clinical equivalence of the SPT Tape for representative common inhalant allergens to conventional SPT in terms of wheal reaction positivity and overall safety. Tests are performed in patients who have a medical history of relevant allergic rhinitis to any of the tested allergens.
Dietary Choice for the Management of Cow's Milk Allergy Influences Other Allergic Manifestations
Food allergy is a common chronic condition in childhood. Recent studies have suggested that the natural history of food allergy has changed during the last two decades, with an increased prevalence, severity of clinical manifestations, and risk of persistence into later ages. The increased food allergy prevalence in children has an important economic impact, with significant direct costs for the healthcare system and even larger costs for the families of food-allergic patients. In addition, children with food allergies are at increased risk to develop other allergic manifestations later in life. According to a recent study, children with a...
Dietary Factors and Disfluency: A Look Into Food Allergies and Other Environmental Triggers Associated With Variations in Severity of Vocal Cord Tension.
The purpose of this study is to see whether participants with persistent developmental disfluency who report fluctuational disfluency due to vocal cord tension on a day to day basis of can achieve a more normalized fluency by identifying dietary allergen responses and subsequently eliminating these dietary triggers from their daily consumption.
Dupilumab and Milk OIT for the Treatment of Cow's Milk Allergy
This is a phase 2, multicenter, randomized, double-blind, parallel group, 2 arm study in approximately 40 subjects aged 4 to 50 years, inclusive, who are allergic to cow's milk. The primary objective is to assess whether dupilumab as an adjunct to milk oral immunotherapy (OIT) compared to placebo improves the safety of milk OIT and rates of desensitization, defined as an increase in the proportion of subjects who pass a double-blind placebo-controlled food challenge (DBPCFC) to at least 2040 mg cumulative milk protein at week 18.
Dupilumab in Eosinophilic Gastritis
40 participants with Eosinophilic Gastritis 18-60 years of age will be randomly assigned with dupilumab or placebo subcutaneous injections every two weeks for a total of 12 weeks. Study subjects who complete the 12-week treatment phase, may continue into an open label extension study, where dupilumab will be administered every two weeks for a total of 24 weeks.
