Functional and Radiological Impairment in Women Highly Exposed To Indoor Biomass Fuels

Abstract

Objective: The aim of this study was to describe the lung function and the computed tomographic features in a selected group of non-smoking women with chronic obstructive pulmonary disease and biomass fuel exposure. Methodology: Thirty female patients currently exposed to biomass smoke were prospectively investigated for further evaluation using high resolution computed tomography (HRCT), pulmonary function tests and blood gas analysis. Results: The mean age was 59±11 years. The patients were exposed to biomass smoke for 37.4± 10 years. Pulmonary function tests revealed severe obstruction. The most common HRCT findings were increased lung volume or diffuse emphysema, thickening of interlobular septae, focal emphysematous areas, increased cardiothoracic ratio, and increased bronchovascular arborization. Conclusion: Biomass fuel has deleterious effects on pulmonary function and structure leading to obstructive and restrictive pathologies.
