Filter by:Anaphylaxis elicited by accidental intake of the offending food constitutes a major health risk to the food allergic patient. Current advice for the food allergic patient is to avoid the offending food allergen and to carry an epinephrine autoinjector. However, novel treatments altering the clinical reactivity to the offending food thereby diminishing the risk of anaphylaxis are much needed. A correlation between the level of specific IgE in serum towards the offending food and the clinical sensitivity of the patient has been suggested. The clinical threshold for a food allergic reaction to occur is therefore hypothesized to increase by reducing the level of specific IgE to the relevant food allergen. Therapy with Omalizumab has proven efficacious in lowering the level of IgE in serum but a high pre-treatment level of total IgE in serum potentially hampers the efficacy in a number of patients, as seen especially in patients with concomitant atopic dermatitis. The aim of this study is to investigate if the combination of initial IgE specific immunoadsorption combined with subsequent treatment with Omalizumab will increase the clinical threshold to the culprit food and thus prevent medical emergencies (anaphylaxis) in patients with severe food allergy.
The primary objective of this study is to determine whether allowing ingestion of sub-threshold amounts of peanut in those with a high threshold (tolerate at least 143 mg peanut protein on supervised double-blind, placebo-controlled oral food challenge [DBPCFC]) will be associated with attaining even higher thresholds over time in children with high threshold peanut allergy compared to those avoiding peanut. The secondary clinical objectives include assessing the development of sustained unresponsiveness (SU, a surrogate term for tolerance without daily ingestion), effects on quality of life, and safety compared to those avoiding peanut. Additionally, this study will phenotype the allergic response to peanut based on threshold and response to exposure. Mechanistic study objectives will determine the immune and molecular basis of the high threshold endotype, identify predictors of response to exposure, and determine mechanisms and biomarkers of remission.
This is a randomised, open-label, controlled study designed to investigate the effect of short-term neonatal skin barrier protection using a commercially available moisturiser on the prevention of atopic dermatitis and food allergy in high risk children.
This study evaluates the effect of a multicomponent intervention applied to restaurant staff about training and nutritional quality of menu improvement, in order to promote a healthy diet and a better management of allergies and intolerances addressed to each family member satisfying the customers with specific needs (allergies and intolerances of food).
Testing of a new ready-to-use Tape in comparison to the currently used skin prick test for the diagnosis of allergies. Assessment of clinical equivalence of the SPT Tape for representative common inhalant allergens to conventional SPT in terms of wheal reaction positivity and overall safety. Tests are performed in patients who have a medical history of relevant allergic rhinitis to any of the tested allergens.
Oral immunotherapy (OIT) is a food allergy treatment where small amounts of the food a child is allergic to is eaten and gradually increased over time with the aim to be able to eat a certain amount of the allergen without experiencing an allergic reaction. While this process works in many children there are concerns about safety, feasibility and drop-outs and how to adapt protocols for multiple allergies. Many OIT trials have targeted approximately 4000mg of single food/day. In these trials up to 40% drop-out. There is evidence much lower doses can have beneficial effects. The investigators will evaluate if low doses of foods can allow for OIT to multiple foods. This approach may have efficacy against accidental exposure and be able to demonstrate immune changes. This approach may have a low burden of treatment and a low rate of allergic reactions and
The study determines how a 6 months oral immunotherapy (OIT) program with hen's egg (HE) effects cellular and humoral immune responses in 50 children with HE allergy. Clinical data, transcriptomics and epigenetics are combined and analyzed by advanced system biology methods. This study will provide better understanding of the effects and mechanisms of OIT.
This protocol will help better define whether patients with peanut and/or tree nut food allergy can tolerate traces in products with precautionary allergen labelling.
Food allergy (FA) is a serious public health concern that causes potentially-life threatening reactions in affected patients. The prevalence of food allergy in the United States (U.S.) has increased substantially and now affects 15 million patients:4-8% of children (6 million children, 30% with multiple food allergies) and about 9% of adults. This is a prospective Phase 2, single-center, multi-allergen OIT study in participants with proven allergies to 2 or 3 different foods in which one must be a peanut. The total of participants in the clinical study will be 110, ages 4 to 55 years with a history of multiple food allergies of 2 to 3 different foods including peanut. Allergy will be confirmed by FA-specific IgE levels and positive skin prick test (SPT). Enrolled participants must be positive during the Double-blind Placebo-controlled Food challenge (DBPCFC) at or before the 300 mg (444 mg cumulative) dosing level of FA proteins.
The purpose of the study is to test a food supplement to: - Show that the food supplement is well tolerated and safe to feed to infants; - Find out how often parents/caregivers feed their infants the food supplement; - Find out how parents/caregivers usually add the food supplement to infants' regular solid or liquid food; and - Learn what aspects of the food supplement are more or less attractive to infants and to parents/caregivers.
