Overview

Allergy is a hypersensitivity reaction in which the immune system responds inappropriately and excessively to normally harmless environmental, dietary, or pharmacological substances known as allergens. The classic mechanism is type I, IgE-mediated hypersensitivity, in which prior sensitization generates allergen-specific IgE that binds mast cells and basophils; on re-exposure, allergen crosslinking triggers degranulation and the release of histamine and other mediators, producing urticaria, angioedema, rhinitis, and, at its most severe, anaphylaxis. Beyond IgE-mediated responses, the Gell and Coombs framework classifies hypersensitivity into types I through IV, including antibody-mediated, immune-complex, and delayed T-cell-mediated reactions; the last underlies allergic contact dermatitis and many delayed drug eruptions. Drug hypersensitivity is a major clinical concern, encompassing immediate and delayed reactions, cross-reactivity among related agents such as NSAIDs and COX-2 inhibitors, and reactions to medical adhesives and other compounds. Diagnosis draws on history, skin and patch testing, in vitro assays, and lymphocyte stimulation testing to identify culprit agents and mechanisms, alongside standardized adverse drug event reporting. Manifestations range across cutaneous, respiratory, and systemic systems. The journal publishes peer-reviewed research on drug hypersensitivity, contact dermatitis, patch testing, and the mechanisms and diagnosis of allergic disease.
