title: Captopril-induced hypersensitivity lung disease. An immune-complex-mediated phenomenon.
abstract: Captopril has not yet been included in the list of drugs causing hypersensitivity lung disease. We report a patient with hypertension, congestive heart failure, and chronic renal failure who, when rechallenged with captopril, developed upper lung field infiltrates associated with productive cough and striking peripheral eosinophilia. Gallium scan, transbronchial biopsy histologic findings, and direct immunofluorescent study were consistent with an immune-complex-mediated hypersensitivity reaction. There was no other etiology discovered for the patient's eosinophilia, nor was there evidence for an infectious etiology to explain his presentation.
