Consensus Report from the Food Allergy Research and Education (FARE) 2019 Oral Immunotherapy for Food Allergy Summit.
Food allergy is a major health problem affecting 5 to 10% of the population in developed nations, including an estimated 32 million Americans. Despite the large number of patients suffering from food allergies, up until the end of January 2020, no treatment for food allergies had been approved by the U.S. Food and Drug Administration […]
Expression and activation of the steroidogenic enzyme CYP11A1 is associated with IL-13 production in T cells from peanut allergic children.
Activation of the steroidogenic enzyme CYP11A1 was shown to be necessary for the development of peanut-induced intestinal anaphylaxis and IL-13 production in allergic mice. We determined if levels of CYP11A1 in peripheral blood T cells from peanut-allergic (PA) children compared to non-allergic controls were increased and if levels correlated to IL-13 production and oral challenge […]
Epitopes with similar physicochemical properties contribute to cross reactivity between peanut and tree nuts.
Many individuals with peanut (PN) allergy have severe reactions to tree nuts (TN) such as walnuts or cashews. Although allergenic proteins in TN and PN have overall low identity, they share discrete sequences similar in physicochemical properties (PCP) to known IgE epitopes. Here, PCP-consensus peptides (cp, 13 aa and 31 aa) were identified from an […]
Effect of Instant Controlled Pressure Drop (DIC) treatment on the detection of nut allergens by Real Time PCR.
Tree nuts show nutritional properties and human health benefits. However, they contain allergenic proteins, which make them harmful to the sensitised population. The presence of tree nuts on food labelling is mandatory and, consequently, the development of suitable analytical methodologies to detect nuts in processed foods is advisable. Real-Time PCR allowed a specific and accurate […]
Preventing food allergy in infancy and childhood: systematic review of randomised controlled trials.
Background: This systematic review of ways to prevent immediate-onset/IgE-mediated food allergy will inform guidelines by the European Academy of Allergy and Immunology (EAACI). Methods: The GRADE approach was used. Eleven databases were searched from 1946 to October 2019 for randomised controlled trials (and large prospective cohort studies in the case of breastfeeding). The studies included heterogeneous interventions, […]
APPEAL‐1: A multiple country European survey assessing the psychosocial impact of peanut allergy.
Background: Peanut allergy (PA) is a common, potentially life-threatening, and typically lifelong condition with a significant burden of illness. However, information is lacking on how persons with PA (PwPA) and their caregivers perceive the psychosocial impact of living with PA. The Allergy to Peanuts imPacting Emotions And Life study 1 (APPEAL-1) survey, conducted across Europe, investigated […]
The Effect of the Food Matrix on the in vitro Bio-Accessibility and IgE Reactivity of Peanut Allergens.
Scope: Factors such as food processing, the food matrix and antacid medication may affect the bio-accessibility of proteins in the gastrointestinal tract and hence their allergenic activity. However, at present they are poorly understood. Methods and results: Roasted peanut flour was incurred into either a chocolate dessert or cookie matrix and bio-accessibility assessed using an in vitro […]
Prevalence of Food Sensitization and Food Allergy in Children across Europe.
Background: For adults, prevalence estimates of food sensitization (FS) and food allergy (FA) have been obtained in a standardized manner across Europe. For children, such estimates are lacking. Objectives: To determine prevalence of self-reported FA, FS, probable FA (symptoms plus IgE-sensitization), and challenge-confirmed FA in European school-age children. Methods: Data on self-reported FA were collected through a screening […]
Identification of cross‐reactive allergens in cashew‐and pistachio‐allergic children during oral immunotherapy.
It has been estimated that around 8% of the children in the U.S. suffer from food allergy and of those, 40% are allergic to multiple foods. Among tree nuts, allergies to pistachios are common in those with cashew nut allergy and multiple homologous allergenic components are shared between the two nuts. Three major allergens from […]
Peanut Oral Immunotherapy: a Current Perspective.
Purpose of the review: Peanut oral immunotherapy (OIT) is one of the most studied experimental therapies for food allergy. With the recently FDA-approved peanut product, Palforzia, the goal of this article is to review the most recent data from clinical trials, discuss recent trends, and anticipate future developments. Recent findings: The latest research suggests that peanut OIT […]
