Induction of Sustained Unresponsiveness to Sesame Using High- and Low-dose Sesame Oral Immunotherapy
This is an experimental, interventional study, following on from a clinical trial comparing the efficacy and safety of oral immunotherapy with low and high doses of sesame protein, in which patient desensitisation was achieved (High and Low Dose Oral Sesame Immunotherapy - Comparison of Efficacy and Safety, NCT05158413). The aim of this study is to assess a sustained unresponsiveness (SU) to sesame protein after at least 8 months of previously assigned high- or low-dose sesame OIT, followed by 4-week-allergen avoidance, and verified by an open oral food challenge (OOFC).

Molecular Basis of Food Allergy
The Study examines the molecular basis of food allergy. It explores the interaction between T cells, InKT cells, basophils and cytokines in the development of food allergy. The study also explores these factors in development of tolerance "outgrowing" food allergy. It will also explore the genetic factors that lead to the development of food allergy. The study examines all type of food allergy including IgE mediated reactions, Eosinophilic Esophagitis and Food Protein Induced Enterocolitis

NiPPeR Randomised Trial - Child Follow Up Study
There is an increasing focus on the need to optimise nutrition, lifestyle and metabolism of parents before and during pregnancy and of the infant after birth, but as yet there is limited understanding of the specific influences and of the underlying mechanisms. This study is a follow up of children from the NiPPeR trial of a nutritional drink enriched with micronutrients, myo-inositol and probiotics taken preconception and during pregnancy. In this setting we will examine the influence of parental nutrition, lifestyle and metabolism before and during pregnancy on child growth, development and well-being; ascertaining growth, adiposity, metabolism, neurobehavioural and health...

Oral Immunotherapy in Young Children With Food Allergy
The goal of this clinical trial is to learn about oral immunotherapy in food allergic children < 30 months of age. The main question it aims to answer is: What is the clinical- and cost-effectiveness of early low-dose oral immunotherapy aimed at long-term tolerance induction. Participants will receive oral immunotherapy for 1 year with a maintenance dose of 300 mg allergenic protein and are compared with food allergic infants not receiving oral immunotherapy to compare with natural tolerance development.

Predictors of Persistent Peanut Allergy at Age 5 Years
The purpose of this study is to determine if avoidance of peanut by children with positive allergy testing to peanut in the first 5 years of life increases the likelihood of developing a persistent peanut allergy by age 5 years. To answer this question, the investigators need to determine which children with positive allergy testing to peanut have reactions after eating peanut (allergic to peanut) and which are able to tolerate eating peanut (not allergic). The investigators plan to conduct double-blind placebo-controlled peanut challenges (gold standard for peanut allergy diagnosis) for CHILD study (http://www.canadianchildstudy.ca) participants who had positive skin prick...

Traditional Asian Diet and Gut Microbiome and Metabolome in Healthy Volunteers and Pregnancy on Infant's Allergy Development
The research aims to elucidate a specially-designed personalized diet based on Traditional Asian Diet and its efficacy in increasing the gut colonization of Prevotella sp. and butyrate levels in pregnant mothers and the benefits in reducing infant's food allergy development.

Allergenicity Assessment of Green Marine Macroalga Ulva sp.
To determine the allergenic potential in humans, we will conduct a three-stage clinical trial. In the first group, 20 healthy volunteers will be involved. All volunteers will be examined by an allergy specialist before enrolment to the study. After receiving informed consent, all volunteers will undergo an allergy skin test to the study seaweed proteins as well as to common allergens. Participants with a skin test showing sensitization will be excluded. Volunteers will be fed by 5 gram of the study seaweed 2 times a week, under supervision, for 6 weeks. After 6 weeks of feeding, skin tests will be repeated. All participants, will undergo an open oral food challenge after one...
