Evaluating Adrenal Insufficiency in Adults With Eosinophilic Esophagitis on Chronic Swallowed Topical Steroids
Eosinophilic esophagitis (EoE), a chronic inflammatory disease of the esophagus, is a clinical and financial burden to patients if left untreated. Often the natural history of the disease includes development of fibrosis and stricturing of the esophagus, acute food impactions, unplanned emergency room visits, and invasive procedures such as endoscopy. Currently there are no Food and Drug Administration (FDA) approved medications for the treatment of EoE. As such, pharmacologic options approved for use in asthma are used for treatment of EoE and include proton pump inhibitors and swallowed topical steroids. These medications are...

Evaluating the Safety and Efficacy of Oral Encapsulated Microbiota Transplantation Therapy in Peanut Allergic Patients
This is a phase II randomized double-blind placebo-controlled trial that aims at evaluating the safety and tolerability of oral encapsulated fecal microbial transplantation therapy (MTT) in peanut allergic patients. In this research the investigators would like to learn more about ways to treat peanut allergies. The primary objective is to evaluate whether MTT with antibiotic pretreatment can increase the threshold of peanut reactivity during a double-blind placebo-controlled food challenge from <=100 mg peanut protein to 300 mg after 28 days of MTT /placebo therapy and 4 months post therapy initiation.

Evaluation of The Food Allergy Mastery Program
The proposed research project will evaluate a novel behavioral intervention that promotes early adolescent food allergy self-management and adjustment through 1) food allergy education, 2) problem-solving, communication, assertiveness, and anxiety management skill building, and 3) peer support.

Feasibility Study of a New Immunoglobulin E (IgE) Assay Method
The main objective is to study the feasibility of a new specific IgE assay using a bioluminescence technique in a pediatric and adult allergic population. For this, we will collect blood, and urine during a blood test scheduled for the follow-up of the patient.

FeNO as a Marker of Allergic Reactions to OFC and Response of OMA Treatment in Multiple FA
This is a Phase IV, open-label, single-center study to evaluate the change in FeNO as a marker of clinical response to OMA in participants with multiple FA.

Fibrostenotic Eosinophilic Esophagitis: Assessment Tools
This protocol addresses a central hypothesis that fibrostenotic Eosinophilic Esophagitis (EoE) is characterized by abnormal esophageal structure and compliance compared to non fibrostenotic EoE and that distinctive cellular and molecular profiles predict the fibrostenotic phenotype. This study aims to define and assess the changes that occur in the structure and dynamics of the esophageal wall in pediatric Eosinophilic Esophagitis along with characterizing the histologic and molecular patterns in fibrostenotic EoE.

Food Allergy in the Brain
Preventing food allergic reactions predominantly relies on allergen avoidance and managing this daily causes high anxiety in some patients, while having an allergic reaction can cause a post-traumatic stress disorder-like syndrome in children. The underlying mechanisms of these psychological changes are poorly understood, but one potential mechanism may be post-natal hippocampal neurogenesis (HN). HN is the production of new neurons from stem cells in the hippocampus which is one of the brain centres for memory and mood regulation. HN has been associated with cognitive function and some psychiatric disorders. Importantly, it can be...

Food-Specific and Component IgE Threshold Levels That Predict Food Allergy in People With Elevated Total Serum IgE Levels and Atopic Dermatitis
Background: Atopic dermatitis (AD), also called eczema, makes skin dry, red, and itchy. People with AD are more likely to get a food allergy than people without AD. But some food allergy tests are not always accurate in people with AD. Researchers want to study if people are truly allergic to milk and/or peanuts. Objectives: To improve the ways doctors test for food allergy in people with AD. Eligibility: People ages 3 21 who have had AD; have a high total IgE level (an allergic antibody); might have a milk and/or peanut allergy; and are currently enrolled in another NIH study Design: ...

GERAP's Epidemiological Survey on Perioperative Hypersensitivity Reactions
Perioperative hypersensitivity reactions are still associated with significant morbidity and mortality despite early recognition and use of epinephrine. The epidemiology of these reactions evolves over time and changes with clinical practice. The main objective is to study the epidemiology of these reactions over a 10-year period, including patient phenotype, reaction phenotype and outcome of the allergic work-up.
