Tolerability of Goat Milk Protein in Eosinophilic Esophagitis Patients With Cow Milk Protein Trigger
Eosinophilic esophagitis (EoE) is a chronic immune mediated disease characterized by eosinophilic infiltration in esophageal epithelium and resulting in esophageal dysfunction. While the exact pathogenesis is yet to be elucidated, EoE is considered an atopic disease. This classification is in part due to the inflammatory infiltrate of eosinophils, basophils and T-cells producing Th2 cytokines, yet it may also be triggered by environmental allergens. In addition, the rates of atopy are approximately 3 times higher in patients with EoE than in the general population. Furthermore, and most convincing, EoE is successfully managed with dietary exclusion of triggering groups in both...

Tolerance in Beekeepers
Beekeepers experience multiple bee stings each year. Many of these beekeepers (25-60%) become sensitized to bee venom through the production of specific antibodies that target the bee venom. Although these antibodies are important in the triggering of an allergic reaction only a small number of sensitised beekeepers go on to have an allergic reaction with symptoms away from the site of the sting. These reactions can be severe and are known as anaphylactic reactions. The study investigates why some beekeepers develop severe allergic symptoms after bee stings while others do not. This study will explore factors in the blood that protect sensitised individuals from having...

TRANS-FOODS: Preventing Peanut Allergy Through Improved Understanding of the Transcutaneous Sensitisation Route, Novel Food Processing and Skin Care Adaptations
This project aims to study the immune responses to peanut allergen in those with a skin barrier defect with and without skin massage, specifically it aims to: 1. Establish if peanut allergen components can pass into human skin through regular massage using the peanut protein-containing extract. 2. Clarify whether this effect is amplified in those with an impaired skin barrier (AD and dry skin vs healthy controls). 3. Assess whether peanut protein components can be detected in interstitial skin fluid (ISF) using a suction device. 4. Test whether peanut protein components present in ISF are able to induce activation of basophils in blood of...

Understanding the Immune System's Role in Tree Nut and Peanut Allergies: Key Biomarkers for Diagnosis and Treatment Monitoring and Treatment Targets
Peanut and tree nuts belong to the main elicitors of pediatric food allergy and are the main cause of near fatal reactions in children requiring emergency management. Oral immunotherapy has emerged as an alternative treatment option for the management of food allergies, to enhance patients' safety and quality of life. Monitoring if the therapy is working relies on oral food challenges during the course of treatment. There is a clear need for reliable biomarkers that are reflective of the clinical progression during oral food challenges and during immunotherapy that would help with patient stratification and possibly for personalized treatment approaches in the future The aim of...

Use of Dexamethasone in Prevention of the Second Phase or a Biphasic Reaction of Anaphylaxis
Anaphylaxis is an acute serious allergic reaction, with multi-organ system manifestations caused by the release of chemical mediators and it is potentially fatal . Between 5% and 14% of patients may experience a recurrence of anaphylaxis 8-12 hours after the initial presentation, called biphasic (late-phase) . The mainstay of treatment for children experiencing anaphylaxis remains adrenaline and H1-antihistamines. Corticosteroids are not life-saving and do not have an immediate effect on the symptoms of anaphylaxis but may help reduce or prevent a biphasic "late phase" reaction . The aim of this study is to compare the efficacy of oral glucocorticoids in prevention of the...

Using Commonly Available Food Products To Treat Food Allergy
Food allergy affects 1 in 30 children, and is the commonest trigger for life-threatening reactions (anaphylaxis) in this age group. It is a major public health issue, with practical implications for industry, education and healthcare systems. Oral immunotherapy (OIT) is an emerging treatment option, where small, increasing doses of a food allergen are used to cause "desensitisation", so food-allergic individuals no longer have symptoms when exposed to the trigger food. However, frequent allergic reactions during OIT (including anaphylaxis) are common, and can lead to patients having to stop treatment. In addition, food-allergic children usually dislike the taste of the food they...

Validation in French of a Quality of Life Questionnaire for Patients With Eosinophilic Esophagitis in Pediatrics
Eosinophilic esophagitis is a chronic condition of the esophagus. The symptoms of eosinophilic esophagitis can affect the quality of life of affected children. There is no French scale to specifically evaluate the quality of life of these patients. It will be a monocentric, prospective, descriptive study carried out at the Nice University Pédiatric Hospital. The main objective of this study will be the validation of a French version of the quality of life pediatric scale (PedsQL) module for eosinophilic esophagitis. It will take place in 2 distinct parts: - The translation of the questionnaire in French. - Collection of the quality of life questionnaires
