Food Allergen Eliminations and Combined Protocols for Obesity Reduction: a Preliminary Comparison Study
Screened subjects will be tested for hidden food allergies. Subjects will eliminate all food that showed leukocyte reactions for 90-days. Subjects will then also be invited to use the Willis Exercise protocol. Body composition testing and Body Mass Index calculation will be accomplished at enrollment and after completion of the 90-day study.
Food Allergen OIT for Shrimp and Cashew
A prospective Phase 2, single-center, single-allergen OIT of cashew or shrimp in participants with proven allergies to either cashew or shrimp, respectively. We intend to treat 72 participants, ages 7 to 55 years with an allergy to either cashew, or shrimp determined by Double Blind-Placebo Controlled-Food Challenge (DBPCFC), allergy history, clinical symptoms, food-allergen (FA)-specific IgE levels, and skin prick test (SPT).
Food Allergy Registry at a Single Site
This is a registry of participants who are interested in being screened for clinical trials at a single site.
Food Antigen in Eosinophilic Esophagitis
The relationship or effect of food antigen (wheat based soy sauce) in eosinophilic esophagitis. It is believed that when food antigens are exposed to the esophageal tissue it starts an chronic allergy-based inflammation. This will be analyzed with the esophageal biopsies and the mucosal impedance probe.
Food Oral Immunotherapy for Peanut Allergy
This is an open label observational single center study of clinical food oral immunotherapy outcomes with biomarker samples and participant and/or caregiver-completed questionnaires in participants between 6 months and 65 years of age with IgE-mediated peanut allergy undergoing food oral immunotherapy.
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: ...
Gradual Egg-tolerance Induction in Hen's Egg Allergic Children
1. The investigators here want to test the hypothesis that a total period of 18 months of gradual open introduction of a certain egg product with regard to full egg tolerance induction is not inferior when compared to a total period of 30 months gradual open introduction of a certain egg product (see steps for the specific egg products) after tolerance for baked egg has been obtained. 2. The investigators also want to define step-specific 'tolerance-failures' and study the relevance of specific IgE to specific egg components to predict failures at each step.
Grass Pollen Immunotherapy Plus Dupilumab for Tolerance Induction
The primary objective of this study is to assess whether the combination of grass allergen sublingual immunotherapy (SLIT) and dupilumab for 2 years is more effective than double placebo in suppressing the nasal allergen challenge (NAC) response to grass pollen at 1 year after completion of study medication.
Growth and Plasma Amino Acids in Infants With CMPA and Treated With a Newly Innovated Amino Acid Formula
The purpose of this study is to determine growth and protein status of infants with cow's milk protein allergy and treated with a newly innovated amino acid formula compared to those with a commercial amino acid formula.
Growth of Infants With Cow's Milk Allergy Fed an Amino Acid-based Formula Containing Two Human Milk Oligosaccharides
The main aim of this study is to provide longitudinal growth data in infants with moderate-to-severe cow's milk allergy fed an amino acid-based formula with two added human milk oligosaccharides.
