[Interstitial pulmonary disease in plaster workers].
Two cases of diffuse interstitial lung disease in plaster workers with clinical, histological and immunological data suggestive of hypersensitivity pneumonitis are presented. Special remark is made on the immunological results, both cellular (increase in activated T cells and Natural Killer cells) and humoral (immunoglobulins) from the bronchoalveolar lavage. We tried to detect the antigen although we did not succeed in its characterization and we discuss the relationship between these two cases and other hypersensitivity pneumonitis. We discuss the importance of the immunological study of cells obtained from bronchoalveolar lavage for the diagnosis of alveolitis with a lymphocytic predominance. Finally, we suggest that 99 Tc-DTPA gammagraphy can be usefull to monitor the evolution of the alveolitis in these patients.
