Filter by:Cow's milk (CM) allergy is the most common food allergy in children, affecting 2-3% of infants. In formula-fed infants with CM allergy, extensively hydrolyzed or amino acid-based infant formulas are typically recommended. These formulas are expensive and not palatable. For older patients with CM allergy, the standard of care is avoidance of all CM products. The investigators cared for a CM allergic patient who was able to tolerate partially hydrolyzed whey formula (pHWF), which tastes better and is less expensive than extensively hydrolyzed or amino-acid based formulas. There are likely other subjects who could similarly tolerate pHWF. Furthermore, it is possible that taking pHWF could accelerate tolerance of CM. The investigators aim to identify characteristics of CM allergic subjects who can tolerate pHWF and assess the degree to which taking pHWF accelerates CM tolerance.
Reintroduction of small doses of food in allergic children to lightening the elimination diet.
This is a phase IIb clinical trial to investigate the efficacy and safety of subcutaneous immunotherapy with a modified parvalbumin called mCyp c 1 for the treatment of fish allergy to subjects allergic to fish.
This pilot study will test the use of visual cues to engage food service workers in protecting patrons with food allergies. Food service workers from Philadelphia quick-service restaurants were recruited to participate in a survey of attitudes that includes an embedded randomized experiment testing an experimental cue (photograph of an allergic child) to increase workers' engagement and empathy.
Patients with food allergy and their parents will answer a food allergy quality of life questionnaire that will be translated to Hebrew and validated. Questionnaires will be filled also by patients undergoing oral immunotherapy (OIT).
Fifteen million Americans suffer from food allergies. Food allergies can be life threatening; the only known life-saving treatment is epinephrine. Adolescents/young adults are at increased risk of adverse events, because of increased risk-taking with food and decreased likelihood of carrying epinephrine. This is a pilot randomized trial to test text message reminders, with and without financial incentives, to encourage allergic young adults to carry epinephrine.
Pilot study to assess the effect of oral immunotherapy on specific Immunoglobulin E (IgE) levels and antigen consumption in two distinct food allergies.
The goal of the study is to determine accurate blood test levels that can predict whether or not subjects are truly allergic to certain foods. In this study, subjects that are clinically documented to be wheat-allergic will participate in a double blind oral food challenge. Blood will be collected from the subject to evaluate the potential allergenicity of proteins introduced into genetically modified crops and evaluate wheat-specific immunoglobulin-e (IgE) antibody reactivity to biotech and conventional wheat varieties.
Primary 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]
Patients with history of a food allergy to hazelnut, walnut or celeriac will undergo food provocation with a dose of the allergenic food to which 5% of the respective food allergic population (ED05) has been calculated to respond with allergic reactions (single shot study). In patients with a hazelnut or peanut allergy a double-blind placebo controlled food challenge with cookies containing either placebo or hazelnut and peanut respectively will be performed to determine threshold levels eliciting an allergic reaction. The results for threshold levels determined by cookie matrix will be compared to the results gained from the EuroPrevall project (matrix comparison study). In patients with a walnut allergy double-blind placebo controlled provocation with walnut will be combined with the intake of proton pump inhibitor (PPI) or with placebo to assess the impact of PPI on the threshold level and on the clinical manifestation.
