title: Immunologic aspects of asthma.
abstract: Asthma often, but not always, is the result of an IgE-mediated allergic reaction to an airborne antigen. The chain of biochemical reactions is now fairly well defined. These reactions generate an immediate smooth muscle bronchoconstriction and a late inflammation 4 to 24 hours later. This article describes the most important allergens in the community, home and workplace, and discusses procedures for diagnosis and management.
