National, Multicenter, Retrospective, Prospective Study to Evaluate Pediatric Gastrointestinal Eosinophilic Disorders
Eosinophilic gastrointestinal disorders (EGIDs) are a heterogeneous group of emerging chronic inflammatory diseases that may affect different gastrointestinal (GI) tracts. Based on the anatomical site involved, EGIDs are distinguished into eosinophilic esophagitis (EoE) and non-esophageal forms, which are subdivided into eosinophilic gastritis (EoG), gastroenteritis (EoGE), and colitis (EoC). EoE is considered the prototype of EGIDs. Since the first description of a case series of patients with EoE, fundamental scientific advances have been achieved, culminating in the redaction of international diagnostic and therapeutic guidelines....
Natural History and Genetics of Food Allergy and Related Conditions
Background: - About 15 million Americans have a food allergy. Because there are no cures or effective prevention or treatment for food allergies, researchers want to learn more about them. Objective: - To learn more about the causes and effects of food allergy and related conditions. Eligibility: - People ages 2 99 who have food allergy and/or a related genetic or other condition - Their relatives - Healthy relatives and volunteers Design: - Participants will have at least 3 visits over 1 2 years, and then once a year for up to 12 years. Each may last a day or longer. ...
Natural History of Severe Allergic Inflammation and Reactions
Background: - Allergic inflammation is central to allergy-related diseases and disorders, such as asthma, food allergies, and atopic dermatitis. Atopic dermatitis, commonly called eczema is a chronic, noncontagious skin condition, usually starting in the first years of life, which causes itching and scaling of an individual s skin. Because atopic dermatitis is a common condition in children who have allergy-related diseases, including asthma, researchers are interested in studying both individuals with atopic dermatitis and their close relatives (parents and children) to better understand how allergy-related diseases develop and ...
Neokare Safety and Tolerability Assessment in Neonates With GI Problems
With an increasing body of evidence to support a causal link between drinking milk that contain cow's milk protein (CMP) and the development of gastrointestinal disturbance in infants, many clinicians avoid the use of CMP containing feed in high risk babies. Delivery of adequate nutritional intake is one of the great challenges in the care of newborn infants, particularly those born preterm or with gastrointestinal problems. Whilst there are recognised benefits of human milk, a diet of exclusive human milk may not meet the nutritional demands of the infant. To close this gap, breast milk fortifier (BMF) is typically added to human...
Non-Immunoglobulin E-mediated Food Allergies in Children
Non-IgE-mediated gastrointestinal food allergies (non-IgE-GIFA) are an evolving web of clinical conditions characterized by subacute and/or chronic symptoms and include food protein-induced enterocolitis syndrome (FPIES), food protein-induced enteropathy (FPE), food protein-induced allergic proctocolitis (FPIAP), and food protein-induced allergic dysmotility disorders (gastroesophageal reflux disease (GERD), colic and constipation) (FPIMD). Despite the prevalence and clinical impact of these conditions, the pathogenesis as well as the natural history and the best management of these disorders are still poorly defined. These...
Nutrition Sufficiency, Allergy Efficacy and Safety of Neocate Jr in Children With Food Protein Allergy
The main purpose of this study is to evaluate efficacy and safety of an amino acid-based formula Neocate Jr in children with food protein allergy, and to evaluate nutrition sufficiency of Neocate Jr in 1 to 10 years old children with food protein allergy.
Omalizumab to Accelerate a Symptom-driven Multi-food OIT
This study will determine the dose-related efficacy of a 20-week treatment of omalizumab started 8 weeks before the onset of a symptom-driven multi-food oral immunotherapy (OIT) protocol at decreasing time to OIT maintenance dose. Two dosages of omalizumab will be compared to placebo during an oral immunotherapy protocol for three simultaneous food allergens.
OMEGA: Outcome Measures in Eosinophilic Gastrointestinal Disorders Across the Ages
The purpose of this observational study is to find the best measures to define how well a person with eosinophilic disorder is doing. People with EoE, EG, EGE and EC normally undergo endoscopy and/or colonoscopy where cells are collected for microscopic analysis. Treatments are then decided based on how the cells look. We are aiming to compare different tissue components such as inflammatory cell types with clinical symptoms. We want to see if scores on standard questionnaires can give us an idea how well the person is doing.
Oral Immunotherapy for Egg Allergy in Children Aged 6 to 16
The aim of the study is to determine the efficacy of a 12-month egg oral immunotherapy (OIT) protocol with a cooked whole egg product including yolk and egg white. Study hypothesis: With this method the risk for severe allergic reaction to egg protein is reduced and the diet can partly or completely be normalized.
Oral Immunotherapy for Young Children With Peanut Allergy - Small Children OIT
Open label study with peanut oral immunotherapy (OIT). Peanut allergic children aged 1-3 years of age will be randomized 2:1 to: 1. Peanut OIT with slow up-dosing (40-60 weeks) up to a maintenance dose of 285 mg daily oral peanut protein or 2. Control group with peanut allergic children who do not undergo OIT. 3. In addition, a group of healthy children without allergic diseases will be included in the study. The primary outcome is tolerance to at least 750 mg peanut protein at a challenge after 3 years and sustained unresponsiveness (i.e. tolerance) to 750 mg peanut protein after 3 years of OIT...
