Prevention of Food Allergies.
This review summarizes the current state of play with regard to food allergy prevention. Food allergy prevention strategies focused on promoting timely introduction of allergenic foods (predominantly peanut) into the infant diet have recently been introduced in several countries. Additional prevention strategies currently under investigation include optimizing infant vitamin D levels, modulating the gut microbiota […]
Food Allergy: A review and update on epidemiology, pathogenesis, diagnosis, prevention and management.
This review provides general information to serve as a primer for those embarking on understanding food allergy and also details advances and updates in epidemiology, pathogenesis, diagnosis and treatment that have occurred over the four years since our last comprehensive review. Although firm prevalence data are lacking, there is a strong impression that food allergy […]
Food Allergy: Update on Prevention and Tolerance.
Of the many possible hypotheses which explain the recent rise in childhood food allergy, the dual allergen exposure hypothesis has been the most extensively investigated. This chapter serves as a review and update on the prevention of food allergy, and focuses on recently published Randomized Controlled Trials (RCTs) exploring the efficacy of oral tolerance induction […]
Characterization of the B-cell receptor repertoires in peanut allergic subjects undergoing oral immunotherapy.
B-cell receptors (BCRs) play a critical role in adaptive immunity as they generate highly diverse immunoglobulin repertoires to recognize a wide variety of antigens. To better understand immune responses, it is critically important to establish a quantitative and rapid method to analyze BCR repertoire comprehensively. Here, we developed "Bcrip", a novel approach to characterize BCR […]
A Targeted LC-MS/MS Method for the Simultaneous Detection and Quantitation of Egg, Milk, and Peanut Allergens in Sugar Cookies.
Food allergy is a growing public health concern, with many individuals reporting allergies to multiple food sources. Compliance with food labeling regulations and prevention of inadvertent cross-contact in manufacturing requires the use of reliable methods for the detection and quantitation of allergens in processed foods. In this work, a novel liquid chromatography-tandem mass spectrometry multiple-reaction […]
Assessing Almond and Peanut Allergens Using Commercially Available Immunoanalytical Kits and LC-MS/MS: A Case Study.
With an ever-increasing allergic population and an emerging market for allergen-free foods, accurate detection of allergens in foods has never been more important. Although ELISA-based methods are the most widely used for detection of allergens in food, there is a need for the development of orthogonal approaches. A commercial ELISA detected a relatively high concentration […]
Highly Sensitive Matrix-Independent Quantification of Major Food Allergens Peanut and Soy by Competitive Real-Time PCR Targeting Mitochondrial DNA.
The development of two competitive real-time PCR assays for the quantitative detection of trace amounts of twomajor food allergens, peanutand soybean, is reported. In order to achieve very low detection levels for both allergens, we established PCR primers and probes targeting mitochondrial DNA sequences. We were able to demonstrate that this approach led to an increase […]
EAACI Guidelines on Allergen Immunotherapy: IgE‐mediated Food Allergy.
Food allergy can result in considerable morbidity, impairment of quality of life, and healthcare expenditure. There is therefore interest in novel strategies for its treatment, particularly food allergen immunotherapy (FA-AIT) through the oral (OIT), sublingual (SLIT), or epicutaneous (EPIT) routes. This Guideline, prepared by the European Academy of Allergy and Clinical Immunology (EAACI) Task Force […]
Integrative transcriptomic analysis reveals key drivers of acute peanut allergic reactions. Nature communications.
Mechanisms driving acute food allergic reactions have not been fully characterized. We profile the dynamic transcriptome of acute peanutallergic reactions using serial peripheral blood samples obtained from 19 children before, during, and after randomized, double-blind, placebo-controlled oral challenges to peanut. We identify genes with changes in expression triggered by peanut, but not placebo, during acute peanut allergic reactions. Network analysis […]
Detection of IgE reactivity to a handful of allergen molecules in early childhood predicts respiratory allergy in adolescence.
BACKGROUND: Sensitization in early childhood may precede respiratory allergy in adolescence. METHODS: IgE reactivity against 132 allergen molecules was evaluated using the MeDALL microarray in sera obtained from a random sample of 786 children at the age of 4, 8 and 16years in a population based birth cohort (BAMSE). Symptoms were analyzed by questionnaire at […]
