Persistence of Oral Tolerance to Peanut
EczemaEgg Allergy2 moreITN049AD (LEAP-On) Study is a continuation of the ITN032AD LEAP Study (NCT00329784). Peanut Allergy, a recognized public health concern, is a common and potentially life-threatening food allergy for which there is no treatment. ITN032AD (LEAP) Study evaluated whether early exposure to peanut promotes tolerance and provides protection from developing peanut allergy in children who are allergic to eggs or who have severe eczema. ITN049AD (LEAP-On) Study will evaluate persistent tolerance to peanut by assessing the effect of twelve months of cessation of peanut consumption in LEAP Study participants who consumed peanut and those who avoided peanut over the previous five years.

FARE Peanut SLIT and Early Tolerance Induction
Peanut HypersensitivityFood Allergy2 morePrimary Objective: To determine if 36 months of peanut SLIT as an early intervention in subjects ages 1 to 4 years induces clinical desensitization. The primary outcome of this objective will be a statistically significant difference in challenge scores between the treatment group versus the placebo group during DBPCFC (Double blind placebo controlled food challenge) performed after 36 months of peanut SLIT (desensitization). Challenge scores are measured by the amount of peanut protein participants are able to ingest successfully without symptoms of an allergic reaction. [Time Frame: Baseline, 36 months] Secondary Objectives: A secondary outcome of this objective will be a statistically significant difference in the challenge score of the treatment group versus the placebo group during the DBPCFC performed 3 months after discontinuing therapy (tolerance). To examine the change in immune parameters associated with peanut SLIT and the development of clinical tolerance. Through this objective, the investigators will seek to understand the molecular processes by which SLIT affects the immune system through evaluation of immune mechanisms in relationship to clinical findings of desensitization and tolerance. The investigators will delineate the impact of peanut SLIT on the subsequent cellular and humoral responses to peanut protein. [Time Frame: Baseline, 39 months]

FAST-Fish -Food Allergy Specific Treatment for Fish Allergy.
Fish AllergyThe aim of this study is to investigate the safety and tolerability of Subcutaneous Immunotherapy treatment (SCIT) with incremental doses of a modified recombinant fish parvalbumin (mCyp c 1) quantified in mass units: To establish a safe dose of the candidate hypo-allergen in human subjects and To study the pharmaco-dynamics of the hypo-allergen administered to human subjects. The study is performed as a placebo-controlled double-blinded randomized trial with 24 fish allergic patients allocated into three different groups of eight.

A Study of Sublingual Immunotherapy in Peanut-allergic Children
Food HypersensitivityThe specific aim of this study is to determine if peanut allergen-specific SLIT will cause clinical desensitization and tolerance to develop in peanut-allergic young children.

Oral Immunotherapy for Childhood Egg Allergy
HypersensitivityImmediate Hypersensitivity1 moreThe purpose of this study is to determine if oral immunotherapy (OIT) will desensitize a child with an allergy to egg and eventually lead to the development of tolerance to egg.

Treatment of Autistic Children Using NAET Procedures
AutismFood AllergiesPurpose of this study is to determine whether NAET procedures are effective in the treatment of children with allergy-related autism spectrum disorders in restoring their verbal and nonverbal communication. Hypothesis: Children in the experimental group will show a significant improvement over the control group in verbal and nonverbal communication as most food allergen groups, environmental allergen groups, childhood immunizations, and some other relevant allergenic substances are desensitized in a systematic way using NAET® procedures within the specified period of study.

Effects of Montelukast in Asthmatic Children With and Without Food Allergy
Bronchial AsthmaFood Allergy1 moreTo search the effects of montelukast on the airway inflammation including FEV1%, FEV1%/FVC, the provocholine® (methacoline chloride powder for inhalation) challenge tests, the leukotriene levels in the exhaled breath condensate in asthmatic children with and without food allergy aged 6-18 years old. To define the patient groups with good response to montelukast and to define the parameters which predict the good response.

Online Mindfulness-based Cognitive Therapy for Parents of Children With Food Allergies
The Quality of Life of Parents of Children With Food AllergyThis study aims to conduct an initial evaluation of adapted, live online, mindfulness-based cognitive therapy for parents and carers of children with food allergies (MBCT-PCCFA).

Promoting Tolerance to Peanut in High-Risk Children
EczemaEgg Allergy1 moreThis study will evaluate whether early exposure to peanuts promotes tolerance and provides protection from developing peanut allergy in children who are allergic to eggs or who have severe eczema. This study has been continued into the ITN049AD (LEAP-On) Study (NCT01366846).

Anxiety About Casual Exposure to Food Allergens
Food AllergyLiving with food allergy may result in anxiety and reduced quality of life. Food allergic patients and their families are often concerned about casual exposure with the offending allergen through skin contact or being near the offending food, which is actually very low risk. This concern can limit social activities and increase stress. The aim of this study is to provide a behavioral intervention consisting of having peanut/tree nut allergic patients hold a cup with a peanut or tree nut to which the patient is allergic to and touching it. The goal is to reduce anxiety about casual exposure to food allergens and improve quality of life for patients with food allergies and their families.
