Cellular profile of bronchoalveolar lavage fluid in Turkish miners.

Abstract:

:Pneumoconiosis is still a health problem in Turkey and has a relatively high incidence. Retired underground miners were investigated to document alveolitis, and to observe the difference in the cellular profiles of bronchoalveolar lavage (BAL) fluid with or without pneumoconiosis. Twenty nine retired male miners and 17 controls, eight non-smokers (four male, four female) and nine smokers (six male, three female), without any dust exposure were evaluated. According to the International Labor Office 1980 classification system, the miners were allocated to three subgroups: eight without pneumoconiosis, 11 with simple pneumoconiosis, and 10 with progressive massive fibrosis (PMF). Spirometric tests and arterial blood gases analysis were done and fibreoptic bronchoscopy and BAL were performed in all subjects. The study and the control subjects were comparable in respect to age, smoking habits, except the non-smoker controls, and the duration of dust exposure, except the controls. The amount of recovered BAL fluid was lower in all miners compared with the non-smoker controls (p<0.05). The amount of recovered BAL fluid and the total cell count correlated significantly (r = 0.48, p<0.01). The percentage of lymphocytes in the BAL fluid of miners without pneumoconiosis and with PMF (p<0.05) and that of simple pneumoconiosis (p<0.01) was significantly lower compared with the non-smoker controls. Alveolitis was not a representative feature of Turkish subjects with an occupational history of underground mining, and BAL fluid cellular profile did not seem to be different in miners with or without pneumoconiosis.
