Evaluation of smoking effect on asbestos pulmonary radiological finding via HRCT
Message:
Abstract:
Asbestos is one of the most important factors in pneumoconiosis. A number of articles point to the role of smoking on intensifying pulmonary changes due to asbestos. High Resonance Computerized Tomography (HRCT) has been advocated as a suitable method for evaluation of pulmonary changes in occupational-exposure to asbestos. The aim of this study was to evaluate the effect of smoking on intensity of pulmonary radiological changes among asbestos workers using HRCT. This study was performed in Nov 2002 among 56 Hajat Chrysotile Asbestos Factory and mine workers located in Nehbandan-Brigand- Khorasan province. The workers were randomly chosen and matched in two groups, smoker (25 individuals) and non-smoker (31 individuals). The level of possible exposure to asbestos in the different areas of the factory and mine was measured. All of the workers were interviewed and underwent HRCT. HRCT was interpretation by 3 radiologists, first separately, then in consultation. The results show, the mean value of asbestos in the respiratory field of asbestos-exposed workers was about 80 times over standard limit (39.75 f/ml; TLV= 0.5 f/ml). HRCT finding demonstrates parenchymal involvement in 39 individuals (69.63%) in form of septal thickening, parenchymal band, subpleural curvilinear lines or band, linear density and ground glass opacity; minimal airway pulmonary diseases in form of air trapping in 3 individuals (5.36%) and pleural involvement in form of pleural plaque or pleural thickening in 30 individuals (53.55%). In addition, 3 single nodules were seen among smoking group. There is significant difference between two groups in pulmonary parenchymal lesions (P<0.01). There is no significant difference between two groups in pleural involvement. Smoking results in significant increase and intensity of asbestos parenchymal lesions. This hazard is severe enough even among light smoker.
