Abstract

A variety of complex pulmonary immunologic responses may follow the inhalation of reactive chemical haptens. Trimellitic anhydride (TMA) is an industrial chemical used as a plasticizer (and serves as a model of occupational immunologic lung disease). Sensitization to TMA can take several forms — IgE-mediated asthma and rhinitis, a late reaction in the lung which resembles hypersensitivity pneumonitis and an irritated airway syndrome. Antibody studies show that TMA can combine with bodily constituents to form new antigenic determinants (NADs) which are probably the most immunogenic form of the compound.
