title: Hypersensitivity pneumonitis and airways hyperreactivity induced by occupational exposure to penicillin.
abstract: A patient with penicillin-induced hyperreactive airways in association with hypersensitivity pneumonitis is described. Patch tests and intradermal tests to penicillin were positive. Bronchoalveolar lavage demonstrated a relative lymphocytosis and mild neutrophilia. Symptoms and physiologic abnormalities of pulmonary function and gas exchange resolved on cessation of exposure to penicillin.
