Peanut allergy

Peanut allergy is an immunoglobulin E (IgE)–mediated hypersensitivity disorder triggered by exposure to proteins found in peanuts (*Arachis hypogaea*) Exposure leads to rapid cross-linking of allergen-specific IgE on mast cells and basophils, resulting in systemic release of inflammatory mediators Clinically, reactions range from acute urticaria, angioedema, pruritus, and vomiting to severe, potentially fatal respiratory compromise, vascular collapse, and systemic anaphylaxis

Primarily affecting children but often persisting lifelong into adulthood, it engages the immune system and multiple organ systems, including the cutaneous, gastrointestinal, respiratory, and cardiovascular tracts Clinically, reactions range from acute urticaria, angioedema, pruritus, and vomiting to severe, potentially fatal respiratory compromise, vascular collapse, and systemic anaphylaxis
