Remission of peanut allergy is associated with rewiring of allergen-driven T helper 2-related gene networks
Background: The immunological changes underpinning acquisition of remission (also called sustained unresponsiveness) following food immunotherapy remain poorly defined. Limited access to effective therapies and biosamples from treatment responders has prevented progress. Probiotic peanut oral immunotherapy is highly effective at inducing remission, providing an opportunity to investigate immune changes. Methods: Using a systems biology approach, we […]
Cashew Oral Immunotherapy for Desensitizing Cashew-Pistachio Allergy (Nut CRACKER Study)
Background: Oral immunotherapy (OIT) is a treatment option for patients with milk, egg and peanut allergy, but data on the efficacy and safety of cashew OIT is limited. Methods: A cohort of 50 cashew-allergic patients aged ≥4 years, who were consecutively enrolled into cashew OIT (target dose 4000 mg protein) between 4/2016-12/2019. Fifteen cashew-allergic patients who […]
Open‐label follow‐on study evaluating the efficacy, safety, and quality of life with extended daily oral immunotherapy in children with peanut allergy.
Background: The benefit of daily administration of Peanut (Arachis hypogaea) Allergen Powder-dnfp (PTAH)-formerly AR101-has been established in clinical trials, but limited data past the first year of treatment are available. This longitudinal analysis aimed to explore the impact of continued PTAH therapeutic maintenance dosing (300 mg/day) on efficacy, safety/tolerability, and food allergy-related quality of life. Methods: We […]
Accurate and reproducible diagnosis of peanut allergy using epitope mapping
Background: Accurate diagnosis of peanut allergy is a significant clinical challenge. Here, a novel diagnostic blood test using the peanut bead-based epitope assay ("peanut BBEA") was developed utilizing the LEAP cohort and then validated using two independent cohorts. Methods: The development of the peanut BBEA diagnostic test followed the National Academy of Medicine's established guidelines with discovery […]
Basophil activation test shows high accuracy in the diagnosis of peanut and tree nut allergy: The Markers of Nut Allergy Study.
Background: Peanut and tree nut allergies are the most important causes of anaphylaxis. Co-reactivity to more than one nut is frequent, and co-sensitization in the absence of clinical data is often obtained. Confirmatory oral food challenges (OFCs) are inconsistently performed. Objective: To investigate the utility of the basophil activation test (BAT) in diagnosing peanut and tree nut […]
The Global Burden of Illness of Peanut Allergy: A Comprehensive Literature Review.
Peanut allergy (PA) currently affects approximately 2% of the general population of Western nations and may be increasing in prevalence. Patients with PA and their families/caregivers bear a considerable burden of self-management to avoid accidental peanut exposure and to administer emergency medication (adrenaline) if needed. Compared with other food allergies, PA is associated with higher […]
Identification of Pru du 6 as a potential marker allergen for almond allergy.
Background: Oral food challenges have demonstrated that diagnosis of almond allergy based on extract-sIgE tests display low specificity. Molecular allergy diagnosis is expected to improve accuracy, but its value in diagnosing almond allergy remains unknown. Objective: To identify relevant almond allergens and examine their ability to improve almond allergy diagnosis. Methods: IgE-reactive proteins were purified from almond kernels. […]
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 […]
Food allergy immunotherapy: OIT and EPIT.
IgE mediated food allergy remains a significant and growing problem across the globe. Of the various treatment modalities, oral immunotherapy (OIT) and epicutaneous immunotherapy (EPIT) have been the best studied. Across various studies of OIT for egg, milk and peanut allergy, strong levels of desensitization have been shown. With egg and peanut OIT, a limited […]
Recent developments and highlights in food allergy.
The achievement of long lasting, safe treatments for food allergy is dependent on the understanding of the immunological basis of food allergy. Accurate diagnosis is essential for management. In recent years, data from oral food challenges have revealed that routine allergy testing is poor at predicting clinical allergy for tree nuts, almonds in particular. More […]
