RESUMO
Alrededor del 40% de la población mundial sigue utilizando combustibles sólidos, entre ellos la leña, para cocinar o calentar sus hogares. La exposición crónica al humo de leña es un factor de riesgo para el desarrollo de enfermedad pulmonar obstructiva crónica (EPOC). En algunas zonas del mundo este factor puede ser más importante que la exposición al humo de tabaco, generalmente inhalado como humo de cigarrillo, como causa de EPOC. Se han descrito diferencias significativas entre la EPOC relacionada con humo de leña (EPOC-L) y la EPOC causada por humo de tabaco (EPOC-T) que han llevado a plantear por algunos autores que la EPOC-L pueda ser considerada un nuevo fenotipo de la EPOC. Presentamos una revisión de las diferencias entre la EPOC-L y la EPOC-T. Basados en que el humo de la leña y el humo del tabaco no son iguales, y que podrían inducir mecanismos fisiopatológicos en algún punto diferentes, hacemos un análisis acerca de si la EPOC-L debe considerarse un fenotipo diferente de la EPOC o una entidad nosológica distinta
Around 40% of the world's population continue using solid fuel, including wood, for cooking or heating their homes. Chronic exposure to wood smoke is a risk factor for developing chronic obstructive pulmonary disease (COPD). In some regions of the world, this can be a more important cause of COPD than exposure to tobacco smoke from cigarettes. Significant differences between COPD associated with wood smoke (W-COPD) and that caused by smoking (S-COPD) have led some authors to suggest that W-COPD should be considered a new COPD phenotype. We present a review of the differences between W-COPD and S-COPD. On the premise that wood smoke and tobacco smoke are not the same and the physiopathological mechanisms they induce may differ, we have analyzed whether W-COPD can be considered as another COPD phenotype or a distinct nosological entity
