Considerations for an approach to individual patient care are highlighted.Ĭopyright © 2020 American Academy of Allergy, Asthma & Immunology. Another early study that reported a similar rate of 8 of any type of allergic reaction from administering cephalosporin in patients with a listed penicillin. The complicating factor of addressing co-allergy, for example, the risks of allergy to both peanut and tree nuts among atopic patients, is also discussed. This review discusses clinically relevant cross-reactivity related to the aforementioned food groups as well as seeds, legumes (including peanut, soy, chickpea, lentil, and others), tree nuts, meats, fruits and vegetables (including the lipid transfer protein syndrome), and latex. This is a list of possible food and plant. Many types of pollen allergies cross-react with. A person allergic to a plant may be allergic to related foods. Allergy and Cross-Reactivity might well be of interest to people who have severe allergies. Low rates are noted for grains (wheat, barley, rye), and rates of cross-reactivity are variable for most other foods. Possible Allergen Plant and Food Cross-Reactivity. Examples of food families with high rates of cross-reactivity include mammalian milks, eggs, fish, and shellfish. Although molecular diagnostics have improved our ability to identify clinically relevant cross-reactivity, the optimal approach to patients requires an understanding of the epidemiology of clinically relevant cross-reactivity, as well as the food-specific (degree of homology, protein stability, abundance) and patient-specific factors (immune response, augmentation factors) that determine clinical relevance. However, many are sensitized to foods without exhibiting clinical reactivity. showed that although cross-reactivity in antibody binding to the spike protein is frequently observed, viral cross-neutralization is uncommon, which is suggestive of a non-neutralizing antibody response to conserved S epitopes with the potential to induce antibody-dependent enhancement. This results in patients having allergic sensitization (positive tests) to many biologically related foods. It discusses the sources and mechanisms of these antibodies, as well as the methods to assess and mitigate their effects on treatment and immunogenicity. The diagnosis and management of food allergy is complicated by an abundance of homologous, cross-reactive proteins in edible foods and aeroallergens. This article reviews the impact of cross-reactive and pre-existing antibodies to therapeutic antibodies on their efficacy and safety.
