A clinical, radiographic, spirometric and blood gas study was done on 63 asbestos exposed symptomatic workers, between 1983-85. Of these 32 were reassessed again in 1986. Though all had dyspnoea, other major symptoms were cough (84%), sputum (39.7%), chest pain (31.8%) and tiredness (25.4%). Only 30.2% showed rales in lung and 3.2% finger clubbing. On follow up tiredness was seen oftener. Radiographically linear (49.2%) and punctate (58.7%) deposits were mainly seen; 50.8% had 1-2 zone disease while 17.5% showed abnormalities in 5-6 zones. On follow up calcified pleural plaques were seen in 18.7% and 6 zone disease in 31.2% cases. By I.L.O. grading, Gr. II disease was seen in 23 and Gr. III in 3 cases. By spirometry 54% were in normal range and significant bronchodilator improvement (>10%) was seen in 14.3%. Overall functional disability was moderate in 6% initially and 53% on follow up. Blood PaO2 abnormalities were detected in 47% cases. The use of multiple criteria helped to pick up most cases of asbestosis and about 50% cases were seen to have progressed over three years.
