Recent advances in understanding and preventing peanut and tree nut hypersensitivity.

Peanut allergy, the most persistent and deadly of the food allergies, has become more prevalent worldwide in recent decades. Numerous explanations have been offered for the rise in peanut allergy, which has been more pronounced in Western, industrialized nations. In infants who are at increased risk of peanut allergy, new evidence indicates that early introduction […]

Managing Cross-Reactivity in Those with Peanut Allergy.

Peanut is an allergenic legume that can cross-react with other plant-based foods, notably other legumes and tree nuts. Peanut allergic individuals can be both co-sensitized as well as co-allergic to such items, requiring foresight when eliciting a clinical history of reaction, in the diagnostic evaluation of such allergies, and in the counseling of patients as to food […]

Prevalence, severity, and distribution of adult-onset food allergy.

Introduction: While much attention has been devoted to food allergy in children, little is known about the prevalence and characteristics of food allergy in adults. Moreover, recent research has shown that increasing numbers of individuals are developing food allergy in adulthood. This population-based study was conducted to examine the prevalence, severity, and distribution of adult-onset […]

AR101 oral immunotherapy for peanut allergy.

BACKGROUND: Peanut allergy, for which there are no approved treatment options, affects patients who are at risk for unpredictable and occasionally life-threatening allergic reactions. METHODS: In a phase 3 trial, we screened participants 4 to 55 years of age with peanut allergy for allergic dose-limiting symptoms at a challenge dose of 100 mg or less […]

Severity of peanut allergy and the unmet gaps in care: a call to action.

Peanut allergy is one of the most common food allergies in children, with a prevalence that has been increasing over the past several decades. The allergy is a type I, immunoglobulin E (IgE)-mediated reaction that commonly presents in childhood and can be associated with an anaphylactic response. There are many theories that attempt to explain […]

Correlation of negative skin-prick test results for tree nuts and successful tree nut challenges among children with peanut allergy.

Background: Children with peanut allergy are regularly instructed to avoid all tree nuts. However, children with peanut allergy are likely not allergic to all tree nuts. Objective: In our cohort of patients with peanut anaphylaxis and who underwent oral immunotherapy, we sought to determine the correlation of skin-prick testing (SPT) results for tree nuts and […]

Comparing the eating out experiences of consumers seeking to avoid different food allergens.

BACKGROUND: Eating outside the home is challenging for consumers with food allergy (FA) and intolerance (FI) and lack of allergen information provision in eating out venues can lead to unnecessary restrictions. Following European legislation (2014) designed to improve allergen information provision, little is known about differences in information provision experienced by consumers seeking to avoid […]
