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

Esophageal String Test in Eosinophilic Esophagitis
The overall goal of this study is to develop a novel minimally invasive device, the Esophageal String Test (EST) to monitor esophageal inflammation during treatment of the rare disease Eosinophilic Esophagitis (EoE) in a safe and efficacious manner. This study is broken down into 2 specific aims: Specific Aim 1: Identify the EoE Biomarker Panel (EBP) that will improve the sensitivity and specificity of the EST for documenting esophageal inflammation in a 1-hour time point. Specific Aim 2: Validate the ability of the EST EBP to monitor therapeutic efficacy in a 1-hour sampling time. Funding Source - FDA OOPD

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...

Fish Oral Immunotherapy in Hong Kong Children
At present there is no cure for food allergy. People with a food allergy need to avoid the food they are allergic to in order to stay safe, but we know that accidental exposure is common. Researchers have begun to look at the effectiveness of 'oral immunotherapy' as a treatment for food allergy but results have been mixed. This study is a randomized controlled trial to evaluate the effectiveness of Fish Immunotherapy (FOIT), with codfish as the primary focus, in inducing tolerance in children with fish allergy compared with Placebo. Children will take increasing doses of codfish protein until a total of 12 months treatment is...

Gradual Egg-tolerance Induction in Hen's Egg Allergic Children Who Tolerate Baked Egg (TETI-II Study)
The investigators want to test the hypothesis that a total period of 12 months of stepwise open egg introduction is not inferior when compared to a total period of 20 months gradual open egg introduction of a certain egg product with regard to full egg tolerance induction.

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.

Immunological Response After Shrimp Oral Immunotherapy Treatment
Oral immunotherapy is effective in desensitized food allergy. Shrimp allergy is increasing in Thailand. So the purpose of our study is to determine level of specific immunoglobulin E antibodies to shrimp, Immunoglobulin G4 and immunoblot analysis in shrimp allergy patients after shrimp oral immunotherapy.

Inflammatory Mediators as Potential Non-Invasive Biomarkers in Subjects With Eosinophilic Esophagitis
The investigators seek to assess esophageal inflammation or lack of it in response to treatment with a novel non-invasive method that would measure eosinophil-associated inflammatory mediators in the blood and urine to determine the presence of active Eosinophilic Esophagitis. For these purposes, the investigators will correlate esophageal inflammatory mediators measured in blood and urine with histological findings identified on esophageal mucosal biopsies. Additionally, biopsies associated mediators will be assessed relative to clinical phenotype and outcome.

Low Dose Multi-OIT for Food Allergy (LoMo)
Oral immunotherapy (OIT) is a food allergy treatment where small amounts of the food a child is allergic to is eaten and gradually increased over time with the aim to be able to eat a certain amount of the allergen without experiencing an allergic reaction. While this process works in many children there are concerns about safety, feasibility and drop-outs and how to adapt protocols for multiple allergies. Many OIT trials have targeted approximately 4000mg of single food/day. In these trials up to 40% drop-out. There is evidence much lower doses can have beneficial effects. The investigators will evaluate if low doses of foods...
