Oral Immunotherapy with Standardized Peanut Extract: A Game-Changer for Peanut Allergy
Peanut allergy is a persistent and potentially life-threatening condition affecting millions worldwide, necessitating effective therapeutic strategies beyond strict avoidance. Oral immunotherapy (OIT) has emerged as a promising approach, with peanut (Arachis hypogaea) allergen powder dnfp (Palforzia Aimmune therapeutics Brisbane Calif]) being the first FDA-approved standardized OIT for peanut allergy. This review synthesizes current clinical evidence […]
Ara h 2105-124-Specific TH2A Cells Drive Peanut Allergy in DRB1*15:01 Individuals: A Detailed Epitope Analysis
Background: The IgE-mediated CD4 T-cell response to peanut (Arachis hypogaea) is heterogeneous, yet TH2 cells remain central drivers of pathology. This study aimed to dissect this complexity at the epitope level by focusing on the HLA-DRB1*15:01-DRB5*01:01 haplotype. Specifically, we examined how distinct epitope-specific T-cell subsets shape the immunological landscape of peanut allergy in peanut-allergic (PA) […]
Immunotherapeutic Approaches to Peanut Allergy Treatment-Pre-Clinical and Clinical Studies: A Comprehensive Review
Peanut allergy is a prevalent and potentially life-threatening condition affecting millions of people worldwide, necessitating strict dietary vigilance. Despite its widespread impact, current treatment options are predominantly limited to allergen avoidance and emergency management of allergic reactions. This review explores contemporary immunotherapeutic strategies aimed at achieving long-term relief for individuals with peanut allergy. We conducted […]
Peanut challenges prior to oral immunotherapy demonstrate high tolerance rates in selected patients
Background: Peanut oral immunotherapy (pOIT) protocols typically remain below the threshold for reaction during the initial dose escalation (IDE) day. However, some patients may have higher thresholds for reaction or may not have an ongoing peanut allergy. Objective: We sought to characterize the response to an accelerated initial dose escalation (A-IDE) for qualifying low-risk peanut-allergic […]
Update on hazelnut allergy: Allergen characterization, epidemiology, food processing technique and detecting strategy
Hazelnuts are popular among people due to their dense nutrient component. However, eating them may be quite dangerous for those who are allergic. To improve food safety, this research examines current developments in the characterization, processing, and detection of hazelnut allergens. The identification and molecular knowledge of certain proteins that cause allergic responses are necessary […]
Efficacy and Safety of Epicutaneous Immunotherapy in Peanut-allergic Children with Atopic Comorbidities
Background: There is a high prevalence rate of atopic comorbidities, including atopic dermatitis (AD), asthma, and concomitant food allergy (CFA), in children with peanut allergy. Objective: To evaluate whether concomitant atopic comorbidities affect the safety and efficacy of VIASKIN® peanut patch (VP250). Methods: EPITOPE was a phase 3, double-blind, placebo-controlled trial designed to assess treatment […]
Maternal supplementation with α-tocopherol inhibits the development of offspring food allergy, H1R signaling and ultimately anaphylaxis early in life
Food allergy has had a rapid rise in prevalence, and thus it is important to identify approaches to limit the development of food allergy early in life. Because maternal dietary supplementation with α-tocopherol (α-T), an isoform of vitamin E, during pregnancy and nursing increases neonate plasma levels of α-T and can limit neonate development of […]
Enhancing the diagnostic accuracy of the IgE crosslinking-induced luciferase expression (EXiLE) method for walnut allergy
Background: Walnut (Juglans regia) frequently triggers nut allergies in the United Kingdom and in the United States, with increasing cases in Japan. While oral food challenges (OFCs) are the definitive method for diagnosing these allergies, they pose the risk of symptom provocation, necessitating safer alternative tests. Our aim here was to evaluate the diagnostic utility […]
The prevalence of peanut-triggered food protein-induced enterocolitis syndrome in a prospective cohort of infants introducing peanut in the first year of life
Background: Since the early introduction of peanut to prevent IgE-mediated peanut allergy, other case series have suggested an increased incidence of peanut-triggered Food Protein Induced Enterocolitis Syndrome (FPIES). Data on the prevalence of peanut-induced FPIES in prospective cohorts are lacking. Methods: The PeanutNL cohort is a prospective cohort that included infants at risk of peanut […]
Basophil Activation Test for the Improved Diagnosis of Peanut and Tree Nut Allergy
Purpose of review: As an ex-vivo test of allergic effector cell activation, basophil activation testing (BAT) to allergen enables quantification of the in-vivo IgE-mediated allergic response. BAT thus holds promise in the diagnosis and monitoring of peanut and tree nut allergies. Recent systematic analyses and expert recommendations support a role for BAT in the diagnosis […]
