“…In a recent cohort study in Mexico, the rate of lung function decline was greater in women with tobaccoassociated COPD compared with biomass-associated COPD (42 mL/y vs 23 mL/y), and those with biomassassociated COPD were older on average and with less severe COPD. 24 It is also interesting that these chronically biomass-exposed women had, on average, . 100% predicted values for FEV 1 and FVC.…”

“…Consistent with this is the reported increased prevalence of an overlap between asthma and COPD [74]. Systemic and pulmonary inflammation is similar to cigarette smoke-induced disease [75,76], with less emphysema [77] and less rapid FEV1 decline [78]. Patients decline more slowly if the biomass exposure is reduced [28], but is not clear whether inhaled therapies used for "usual COPD" are of similar efficacy.…”

As knowledge of airways disease has grown, it has become apparent that neither chronic obstructive pulmonary disease (COPD) nor asthma is a simple, easily defined disease. In the past, treatment options for both diseases were limited; thus, there was less need to define subgroups. As treatment options have grown, so has our need to predict who will respond to new drugs. To date, identifying subgroups has been largely reported by detailed clinical characterisation or differences in pathobiology. These subgroups are commonly called "phenotypes"; however, the problem of defining what constitutes a phenotype, whether this should include comorbid diseases and how to handle changes over time has led to the term being used loosely.In this review, we describe subgroups of COPD and asthma patients whose clinical characteristics we believe have therapeutic or major prognostic implications specific to the lung, and whether these subgroups are constant over time. Finally, we will discuss whether the subgroups we describe are common to both asthma and COPD, and give some examples of how treatment might be tailored in patients where the subgroup is clear, but the label of asthma or COPD is not. @ERSpublications Summary of subgroups of airways disease that can be found in COPD and asthma, and their management

“…COPD caused by biomass smoke (B-COPD) differs from COPD related to tobacco (T-COPD), for example, it has a slower decline of FEV 1 and a different distribution of phenotypes [8][9][10] . However, there are few data regarding the prevalence of comorbidities in both disease types.…”

Background: Comorbidities are very common in chronic obstructive pulmonary disease (COPD), contributing to the overall severity of the disease. The relative prevalence of comorbidities in COPD caused by biomass smoke (B-COPD), compared with COPD related to tobacco (T-COPD), is not well known. Objectives: To establish if both types of COPD are associated with a different risk for several major comorbidities. Method: The prevalence of comorbidities was compared in 863 subjects with B-COPD (n = 179, 20.7%) or T-COPD (n = 684, 79.2%). Multivariate analysis was carried out to explore the independent relationship between comorbidities and type of exposure. Results: Three comorbidities were more frequent in T-COPD than in B-COPD: ischemic heart disease (11.5 vs. 5.0%, respectively, p = 0.01), peripheral vascular disease (9.2 vs. 2.7%, p = 0.006), and peptic ulcer disease (4.8% vs. 0, p = 0.005). After correcting for potential confounding variables, the risk of ischemic heart disease was lower in B-COPD than in T-COPD (OR: 0.33, 95% CI: 0.16-0.69, p = 0.003). Conclusions: The prevalence of ischemic heart disease is significantly lower in B-COPD than in T-COPD, suggesting a different systemic effect of both types of smoke in COPD patients.

FEV₁ Decline in Patients with Chronic Obstructive Pulmonary Disease Associated with Biomass Exposure

Abstract: In the biomass exposure COPD group the rate of FEV1 decline is slower and shows a more homogeneous rate of decline over time in comparison with smokers. The rapid rate of FEV1 decline is a rare feature of biomass-induced airflow limitation.
