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 completed. Children will be tested for fish allergy...

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.

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.

Influence on Cough and Airway Symptoms by Oral Capsaicin
Study objectives To establish whether an oral intake of Capsicum oleoresin; capsaicinoids expressed as 0.4 mg capsaicin (C18H27N03; Mw: 305.4) in each capsule (from chili extract) can desensitise the cough reflex and improve unexplained coughing. Study period - Estimated Start date (first patient enrolled) June 2019 - Estimated End date (last patient completed follow up) June 2020 - First data available for presentation September 2020 Investigational product/comparator The formulation is prepared from Capsicum oleoresin. Each capsule will contend a dose corresponding to 0.4 mg capsaicin. All test methods are as per the European Pharmacopoeia for Capsicum...

Intervention to Reduce Early (Peanut) Allergy in Children
iREACH is a five-year NIH funded study aimed at assessing and improving pediatric clinician adherence to the 2017 NIAID Prevention of Peanut Allergy (PPA) Guidelines. iREACH has been developed as an electronic health record (EHR) integrated Clinical Decision Support (CDS) tool together with educational modules on the PPA guidelines to assist clinicians in implementing the 2017 NIAID PPA Guidelines. A practice-based, two-arm, cluster-randomized clinical trial will evaluate the effectiveness of iREACH in increasing pediatric clinician adherence to the PPA Guidelines and explore the end-goal of reducing peanut allergy incidence by age 2.5 years in the intervention vs control...

Low Dose Multi-Nut Oral Immunotherapy in Pre-schoolers with a Multi-Nut Allergy
The LMNOP trial will be a 2-armed, open-label, randomised controlled trial (RCT), 2:1. Over a period of 18 months, children in the Multi-Nut Oral Immunotherapy Treatment (OIT) Group (experimental arm) will undergo low dose OIT to two nuts they are allergic to. At this time, children in the Standard Care Group (control arm) will be instructed to strictly avoid consuming two nuts they are allergic to. Avoiding consuming nut allergens is the standard care advice for children with peanut/tree nut allergies in Australia. The trial will assess the difference in the proportion of participants undergoing Multi-Nut OIT who can achieve sustained unresponsiveness (SU) compared to the...

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 can allow for OIT to multiple foods. This approach...

Mechanisms of Anaphylaxis
The purpose of this study is to explore different mechanisms for anaphylaxis and find novel biomarkers for this hypersensitivity syndrome. The study participants are patients with anaphylaxis, patients with mild allergic reactions, and patients with febrile transfusion reactions. The investigators will also include a group of healthy controls.
