Observatory of the Lille Paediatric Allergy Unit
The goal of this study is to set up a paediatric observatory within the allergology department of The saint Vincent Hospital, Lille. The study aims to: • Collect exhaustive prospective data from patients eligible for oral immunotherapy. This prospective observatory will enable statistical analyses to be carried out on common food allergens such as hazelnut, cashew nut, pistachio and others.

Observatory on Cow's Milk Protein Allergy
The purpose of this study is to describe the symptoms and their evolution up to the age of 5 years in a population of newly diagnosed infants with a suspected or confirmed allergy to cow proteins, for whom the doctor prescribed the Pepticate® Syneo® replacement formula as soon as they were diagnosed. The Pepticate® Syneo® product is an advanced protein hydrolyzate, food type intended for special medical purposes. This is a product already available on the market.

OMEGA: Outcome Measures in Eosinophilic Gastrointestinal Disorders Across the Ages
The purpose of this observational study is to find the best measures to define how well a person with eosinophilic disorder is doing. People with EoE, EoG, EoN and EoC normally undergo endoscopy and/or colonoscopy where cells are collected for microscopic analysis. Treatments are then decided based on how the cells look. We are aiming to compare different tissue components such as inflammatory cell types with clinical symptoms. We want to see if scores on standard questionnaires can give us an idea how well the person is doing.

Once Daily Versus Twice Daily Budesonide Orodispersible Tablets for Induction of Remission in EoE
The purpose of this study is to prove the non-inferiority of a 6-weeks treatment with 1 mg budesonide orodispersible tablets BID versus 2 mg budesonide orodispesible tabletss for the induction of clinico-pathological remission in adult patients with active eosinophilic esophagitis.

Optimizing the Diagnostic Approach to Cephalosporin Allergy Testing
Cephalosporin antibiotics are commonly used but can result in allergic reactions and anaphylaxis. There is no clear diagnostic approach for cephalosporin-allergic patients, and guidance for the use of other antibiotics in allergic patients is based on side chain chemical similarity and limited skin testing evidence. This project includes a clinical trial and mechanistic studies to optimize the approach to cephalosporin allergy and advance future diagnostics.

Oral Immunotherapy for Egg Allergy in Children Aged 6 to 16
The aim of the study is to determine the efficacy of a 12-month egg oral immunotherapy (OIT) protocol with a cooked whole egg product including yolk and egg white. Study hypothesis: With this method the risk for severe allergic reaction to egg protein is reduced and the diet can partly or completely be normalized.

Oral Immunotherapy for Peanut Allergic Patients
Multicenter, double-blind, randomized, placebo-controlled phase I/II study to determine the safety, tolerability, potential efficacy and dose finding of INP20, an oral immunotherapy in peanut-allergic patients. The overall study design consists of two sequential periods of Part A and Part B. Part A is a dose escalation study in patients from 12 to 65 years old with a history of immediate hypersensitive reaction to peanut protein. Six diferent oral-dose of INP20 will be administered to 6 cohorts of patients once daily for 2 weeks. Part B is a 6-month double-blind, placebo-controlled, randomized and parallel groups study. Patients will be randomized in a 1:1:1 ratio into three...

Oral Itraconazole Versus Combination of Systemic Glucorticoids and Oral Itraconazole in CPA-ABPA Overlap Syndrome
While ABPA and CPA represent two distinct manifestations of Aspergillus-related lung disease, there is an overlap of investigations that are currently used for the diagnosis of these entities. In a previous study, the authors have demonstrated that 22% of subjects with CPA fulfilled the obligatory criteria for ABPA. While the preferable therapy in patients with ABPA is systemic glucocorticoids, the primary therapy in CPA is oral triazoles. However, a different management protocol in the "overlap group" with low doses of glucocorticoids and triazoles, needs to be systematically explored. In this study the investigators intend to compare the clinical outcomes in subjects with...

Oral N-acetylcysteine for Retinitis Pigmentosa
Retinitis pigmentosa (RP) is an inherited retinal degeneration caused by one of several mistakes in the genetic code. Such mistakes are called mutations. The mutations cause degeneration of rod photoreceptors which are responsible for vision in dim illumination resulting in night blindness. After rod photoreceptors are eliminated, gradual degeneration of cone photoreceptors occurs resulting in gradual constriction of side vision that eventually causes tunnel vision. Oxidative stress contributes to cone degeneration. N-acetylcysteine (NAC) reduces oxidative stress and in animal models of RP it slowed cone degeneration. In a phase I clinical trial in patients with RP, NAC taken by...

Patient-Centered Decision Support for Eosinophilic Esophagitis
The study team is conducting this project to learn more about how patients with eosinophilic esophagitis (EoE) like to use and receive educational materials about treatment options and treatment decision making. This study will assess the efficacy of a decision support intervention to make decisions about treatment and disease management for patients with EoE and will assess the feasibility and acceptability of the intervention to inform future R01-level studies. The study team hypothesize that deploying the intervention will be feasible, and it will demonstrate high acceptability among EoE patients. Additionally, that patients that use the intervention (vs general education...
