Commercial Claims Costs Related to Healthcare Resource Use Associated With a Diagnosis of Peanut Allergy.
Background: Peanut allergy (PA) affects ∼1.6 million US children. The current standard of care is strict avoidance and prompt reaction treatment. PA healthcare costs and healthcare resource utilization (HCRU) are poorly understood. Objective: To estimate PA healthcare costs and HCRU using a nationally representative commercial payer database. Methods: The IBM MarketScan ® Commercial Claims and Encounters Database was […]
Vaccine against peanut allergy based on engineered Virus-Like-Particles displaying single major peanut allergens.
Background: Peanut allergy is a severe and increasingly frequent disease with high medical, psychosocial and economical burden for affected patients. A causal, safe and effective therapy is not available. Objective: We aimed to develop an immunogenic, protective and non-reactogenic vaccine candidate against peanut allergy based on Virus-like Particles (VLPs) coupled to single peanut allergens. Methods: To generate vaccine […]
Comparative analysis of eliciting capacity of raw and roasted peanuts: the role of gastrointestinal digestion.
This study investigated the simultaneous impact of food matrix and processing on the food allergy eliciting capacity of peanuts in a physiologically relevant context. Whole raw and roasted peanuts were subjected to in vitro digestion combining the harmonized oral-gastric-duodenal digestion models with brush border membrane enzymes (BBM) to simulate the jejunal degradation of peptides. SDS-PAGE […]
Advances in the management of peanut allergy (oral immunotherapy and epicutaneous immunotherapy).
Background: Peanut allergy affects up to 2% of the general population and carries not only the risk of potentially life-threatening allergic reactions but also negatively impacts day to day life for patients and their families. Advances in knowledge in immunotherapy is providing families with options for proactive treatment. Objective: To examine the available data for oral immunotherapy (OIT) […]
Real-world tree nut consumption in peanut-allergic individuals.
Background: Individuals with peanut allergy often avoid tree nuts, yet true rates of tree nut allergy in peanut-allergic individuals are as low as 7%. Objective: To examine tree nut sensitization patterns in peanut-allergic individuals, patient and family choice regarding tree nut consumption, and factors that influence consumption of tree nuts. Methods: All patients presenting for […]
Defining challenge-proven coexistent nut and sesame seed allergy: A prospective multicenter European study.
Background: Peanut, tree nut, and sesame allergies are responsible for most life-threatening food-induced allergic reactions. Rates of coexistent allergy between these foods have been from mostly retrospective studies that include only a limited number of tree nuts or were not based on oral food challenges. Objective: The Pronuts study is a multicenter European study (London, […]
Current perspectives on peanut allergy.
Peanut allergy is increasingly prevalent and for most patients is a life-long condition, with the potential to cause life-threatening reactions. Accurate diagnosis and appropriate management are essential to minimise risks due to accidental peanut exposure. Current management strategies focus on strict allergen avoidance and access to emergency medicines to treat potential reactions; however, active approaches […]
Selection of universal peptide biomarkers for the detection of the allergen hazelnut in food trough a comprehensive, high resolution mass spectrometric (HRMS) based approach.
The interest of using LC-MS/MS as a method for detection of allergens in food is growing. In such methods, peptides are used as biomarkers for the detection and quantification of the allergens. The selection of good biomarker peptides is of high importance to develop a specific, universal and sensitive method. Biomarkers should, for example, be […]
Prevention of Non-peanut Food Allergies.
Purpose of review: The purpose of this review article is to discuss the recent literature around methods of prevention of food allergies other than peanut allergy. Recent findings: While the most robust data to date exists for peanut, there are emerging studies suggesting a beneficial effect to early introduction of cooked egg, and cow's milk […]
Sustained Successful Peanut Oral Immunotherapy Associated with Low Basophil Activation and Peanut-Specific IgE.
Background: Oral immunotherapy (OIT) can successfully desensitize many peanut allergic subjects, but clinical tolerance diminishes over time upon discontinuation, or low dose maintenance, of peanut. Therefore, in order to improve the efficacy and sustainability of such therapy, we sought to identify biomarkers and clinical tools that can predict therapeutic outcomes and monitor treatment responses. Objective: We evaluated […]
