Immune signatures predicting the clinical outcome of peanut oral immunotherapy: where we stand
Peanut allergy is a growing health concern that can cause mild to severe anaphylaxis as well as reduced quality of life in patients and their families. Oral immunotherapy is an important therapeutic intervention that aims to reshape the immune system toward a higher threshold dose reactivity and sustained unresponsiveness in some patients. From an immunological […]
Early Peanut Introduction in Infants: Improving Guideline Adherence With EMR Standardization
Objectives: Peanut allergy in children is a population health problem. Evidence suggests early peanut introduction (EPI) for infants can reduce the development of peanut allergy. Primary care settings have not widely adopted guidelines recommending EPI. Peanut allergy prevention depends on primary care providers incorporating EPI guidelines into well-child check (WCC) encounters. We aimed to improve […]
Fast impedimetric immunosensing of IgGs associated with peanut and hazelnut allergens
Food allergies trigger a variety of clinical adverse symptoms and clinical evidence suggests that the presence of food allergy-related IgG can be helpful in the diagnosis when analyzed at the peptide-epitope level. To validate and select the peptides based on their specificity toward hazelnut or peanut epitopes, the authors of this study developed a silicon-based […]
EAACI guidelines on the diagnosis of IgE-mediated food allergy
This European Academy of Allergy and Clinical Immunology guideline provides recommendations for diagnosing IgE-mediated food allergy and was developed using the Grading of Recommendations, Assessment, Development and Evaluations (GRADE) approach. Food allergy diagnosis starts with an allergy-focused clinical history followed by tests to determine IgE sensitization, such as serum allergen-specific IgE (sIgE) and skin prick […]
Prevalence of tree nut allergy in Europe: A systematic review and meta-analysis
In 2014, the European Academy of Allergy and Clinical Immunology (EAACI) published the first systematic review that summarized the prevalence of food allergy (FA) and food sensitization in Europe for studies published 2000-2012. However, only summary estimates for tree nut allergy (TNA) were feasible in that work. In the current update of that systematic review, […]
Revised Swedish infant feeding guidelines are associated with earlier introduction of allergenic foods.
Background: Randomized controlled trials have demonstrated that early introduction of allergenic foods, such as peanut and egg, can reduce food allergy in high-risk children. Many international guidelines recommend introduction in the first year of life and accordingly, the Swedish National Food agency released updated guidelines in June 2019. Objective: To examine if the age at […]
Safety and effectiveness of peanut oral immunotherapy in children under 12 months
Peanut oral immunotherapy is an option for the treatment of peanut allergy. Our study suggests that peanut oral immunotherapy in children aged less than 12 months is safe and effective. https://doi.org/10.1016/j.jaip.2023.07.009
The relevance of oral food challenge in a patient allergic to peanut and tree nuts
Peanut allergy is one of the most common food allergies in childhood. In vitro cross-sensitization between peanut and tree nuts (TN) is high, but only a subgroup of patients allergic to peanut will have a concomitant allergy to one or several TN. In this article, the authors report a case of a 12-year-old boy who […]
Reactivity to allergenic food contaminants: A study on products on the market
Background: The frequency and severity of reactions in food-allergic consumers exposed to unintentional food allergen contamination during production is unknown. To warn allergic consumers, it has been suggested for pre-packaged foods to be precautionary labelled when the food allergen contamination may exceed the amount to which 1%-5% of the population could react (ED01-ED05). ED01 for […]
Citrin: a novel food allergen in citrus seeds and citrus-derived pectin that shows cross-reactivity with cashew and pistachio
Background: Patients exquisitely sensitive to cashew/pistachio are at risk for allergic reactions to citrus seeds and pectin. Objective: In this study, we sought to examine whether pectin is contaminated with citrus seeds, to identify a culprit antigen in citrus seeds, and to assess for cross-reactivity among allergens in citrus seeds, citrus pectin, and cashew/pistachio. Methods: […]
