Response to pulmonary rehabilitation in women with COPD: Comparison between disease associated with wood smoke and cigarette

Introduction: Chronic obstructive pulmonary disease is an entity with high morbidity and mortality that is mainly generated by exposure to cigarette smoking and exposure to wood smoke; previous studies have shown increasing interest between the 2 types of exposure. Objective: To compare the effect of pulmonary rehabilitation in patients with chronic obstructive pulmonary disease who have had exposure to cigarettes versus patients exposed to biomass wood smoke in a fourth level clinic in Santiago de Cali (Colombia). Materials and methods: Prospective and longitudinal study, all patients who attended from January 2016 to December 2017 were recruited and met the inclusion criteria, later they were divided into 2 groups: Wood Smoke and Cigarette. Pulmonary function tests, health-related quality of life assessment, symptom assessment and comparison of functional aerobic capacity were recorded with the six-minute walk test and estimated oxygen consumption before and after rehabilitation. Results: Fifteen patients with exposure to wood smoke and 17 to cigarettes completed the rehabilitation. In the intragroup comparison, significant differences (P < .05) were found in the distance traveled, in modified Medical Research Council dyspnea scale (mMRC) the estimated oxygen consumption, also in the Saint George Respiratory Questionnaire. In the comparison between groups, no differences were found in the variables studied. Conclusion: Pulmonary rehabilitation generated clinics changes significant in the variables studied in the 2 types of exposure; these changes being similar in the 2 groups studied in the present investigation.
