Bronchoalveolar lavage (BAL) findings in 27 individuals with crocidolite- or chrysotile-induced asbestosis were compared to BAL findings in 29 unexposed control subjects. Alveolitis, defined as an increase in the proportions and/or absolute numbers of inflammatory cells present in BAL fluid compared to values in control subjects, was present in 26 (96 percent) subjects with asbestosis. Most exhibited a neutrophil-eosinophil alveolitis, with neutrophil proportions increased to 7.4 +/- 0.7 percent and eosinophil proportions increased to 2.2 +/- 0.4 percent, compared to 2 +/- 0.5 percent and 0.4 +/- 0.01 percent, respectively, in control subjects (p less than 0.01 for both neutrophils and eosinophils). An increase in the total number of neutrophils and eosinophils per ml of lavage fluid was also seen (neutrophils 23 +/- 5 and eosinophils 13 +/- 4 per ml; p less than 0.05 compared to control subjects). Severity of the alveolitis, defined by the neutrophil or eosinophil proportions, was independent of a history of exposure to cigarette smoke. The pattern and severity of alveolitis in crocidolite- and chrysotile-induced asbestosis were similar. There was a significant correlation between duration of exposure to asbestos and neutrophil proportions (p less than 0.01). No significant difference in the severity of the alveolitis was observed between individuals with radiologic and physiologic evidence of asbestosis compared to those with asbestos exposure and crackles alone, suggesting that, in asbestosis as in other chronic interstitial lung diseases, radiologic and physiologic parameters do not reflect the severity of the alveolitis. This study demonstrates that a neutrophil-eosinophil alveolitis is present in individuals with crocidolite- and chrysotile-induced asbestosis, that this alveolitis is independent of cigarette smoking, and that the severity of the BAL changes is not reflected in radiologic and physiologic changes.
