Oral immunotherapy using boiled peanuts for treating peanut allergy: An open‐label, single‐arm trial.
Background: Peanut allergy affects 1%–3% of children in Western countries. Boiling peanuts has been demonstrated to result in a hypoallergenic product that may provide a safer way of inducing desensitization in peanut-allergic patients by first inducing tolerance to boiled peanut. We aimed to assess the efficacy and safety of oral immunotherapy (OIT) using sequential doses […]
Microplastics reduce nitrogen uptake in peanut plants by damaging root cells and impairing soil nitrogen cycling.
Microplastic (MP) pollution severely impairs the sustainable development of modern agriculture. However, the mechanisms underlying the effects of MP contaminants on nutrient cycles in agroecosystems are poorly understood. In this study, we examined the impacts of two types of MPs, polypropylene (PP) and rubber crumb (RC), on nitrogen (N) transformation and N cycling in soil-peanut […]
Early introduction of peanut reduces peanut allergy across risk groups in pooled and causal inference analyses.
Background: The LEAP study has shown the effectiveness of early peanut introduction in prevention of peanut allergy (PA). In the EAT study, a statistically significant reduction in PA was present only in per-protocol (PP) analyses, which can be subject to bias. Objective: To combine individual-level data from the LEAP and EAT trials and provide robust […]
Management of Anaphylaxis During Peanut Oral Immunotherapy.
Background: Peanut oral immunotherapy (POIT) has emerged as an active management option for peanut allergy, with an FDA-approved product now available for therapy. Allergic reactions, including anaphylaxis, can occur during therapy and their management is key in optimizing this treatment and patient outcomes. Purpose of review: In this manuscript, we will review the rates of […]
Prevalence of Food Allergy in France up to 5.5 Years of Age: Results from the ELFE Cohort.
Background: In France, updated data on food allergies (FAs) are lacking, despite the need for efficient FA management and prevention. This study aimed to evaluate the prevalence of FAs in children in France, describe the most common allergens and determine the prevalence of atopic diseases in children with FAs. Methods: The ELFE study comprises a […]
Efficacy and safety of food allergy oral immunotherapy in adults.
Background: Oral immunotherapy (OIT) is an emerging method for treating food allergy in children. However, data regarding adults undergoing this process are lacking. Methods: We retrospectively analyzed the medical records of patients with food allergy aged ≥17 years who completed OIT treatment between April 2010 and December 2020 at Shamir Medical Center. Data were compared […]
Predictors of anaphylaxis to peanut and tree nuts in a Mediterranean population.
Background: Peanuts (PN) and tree nuts (TN) are major causes of anaphylaxis worldwide. We aimed to determine the clinical and demographic characteristics associated with anaphylaxis in patients sensitized to PN and/or TN in a Mediterranean population. Methods: We conducted a retrospective study, which included 198 patients allergic to PN and/or TN (allergy symptoms plus specific […]
One-class model with two decision thresholds for the rapid detection of cashew nuts adulteration by other nuts.
A green screening method to determine cashew nut adulteration with Brazilian nut, pecan nut, macadamia nut and peanut was proposed. The method was based on the development of a one-class soft independent modelling of class analogy (SIMCA) model for non-adulterated cashew nuts using near-infrared (NIR) spectra obtained with portable equipment. Once the model is established, […]
Novel peanut-specific human IgE monoclonal antibodies enable screens for inhibitors of the effector phase in food allergy.
Background: 10% of US residents have food allergies, including 2% with peanut allergy. Mast cell mediators released during the allergy effector phase drive allergic reactions. Therefore, targeting sensitized mast cells may prevent food allergy symptoms. Objective: We used novel, human, allergen-specific, IgE monoclonal antibodies (mAbs) created using human hybridoma techniques to design an in vitro […]
Cytometric analysis reveals an association between allergen-responsive natural killer cells and human peanut allergy.
Food allergies are a leading cause of anaphylaxis, and allergen-specific immune responses in both the innate and the adaptive immune system play key roles in its pathogenesis. We conducted a comprehensive phenotypic and functional investigation of immune cell responses from nonallergic (NA) and peanut allergic (PA) participants cultured with media alone or peanut protein and […]
