title: Allergen-induced inflammation and the role of immunoglobulin E (IgE).
abstract: The prevalence of common allergic disorders such as asthma, allergic rhinitis, and atopic dermatitis has increased significantly in the past 30 years. The impact of these atopic diseases on the patient and the health care system is considerable: Allergic disorders are associated with a high degree of morbidity, which can profoundly impact patient quality of life and health care resource use. Existing strategies to treat allergic disorders beyond simple allergen avoidance focus on diminishing or eliminating the recurrent and/or persistent signs and symptoms that characterize the allergic response. A new strategy has been developed that uses antibodies directed against immunoglobulin E (IgE) to prevent it from binding to cells bearing its receptors and thus neutralizing the allergic response before it begins. These new agents reduce allergic responses in atopic individuals and improve their symptoms while reducing rescue medication and corticosteroid use in patients with allergic asthma or seasonal allergic rhinitis. Thus, anti-IgE antibodies represent proof that IgE plays a central role in allergic reactions and that anti-IgE therapy is a potentially effective treatment for allergic disease.
