Incidence and profile of severe exacerbations of chronic obstructive pulmonary disease due to biomass smoke or tobacco.

Introduction And Objectives: Stable chronic obstructive pulmonary disease (COPD) caused by biomass smoke (B-COPD) has some differences from tobacco-induced-COPD (T-COPD), but acute exacerbations (AECOPD) have not been well characterized in B-COPD.

Objective: To compare the incidence, characteristics and outcomes of AECOPD in B-COPD with those of T-COPD.

Methods: A retrospective observational study that included consecutive patients seen at a specialized COPD clinic (2008-2021).

Diagnostic delay of associated interstitial lung disease increases mortality in rheumatoid arthritis.

Rheumatoid arthritis (RA) is a systemic autoimmune disease whose main extra-articular organ affected is the lung, sometimes in the form of diffuse interstitial lung disease (ILD) and conditions the prognosis. A multicenter, observational, descriptive and cross-sectional study of consecutive patients diagnosed with RA-ILD. Demographic, analytical, respiratory functional and evolution characteristics were analyzed to evaluate the predictors of progression and mortality.

Phenotype-Guided Asthma Therapy: An Alternative Approach to Guidelines.

Despite recent advances in therapy, a substantial proportion of asthmatics remain not well controlled. The classical stepwise approach to pharmacological therapy in adult asthma recommends that treatment is progressively stepped up by increasing the inhaled corticosteroid (ICS) dose or by adding another controller medication- to achieve symptom control and reduce the risk of exacerbations, and stepped down after a period of control. In general, asthma guideline recommendations do not reflect that there are significant differences between ICS in terms of potency.

Mortality in COPD patients according to clinical phenotypes.

Purpose: Grouping COPD subjects into clinical phenotypes might be useful for the management of the disease, but the clinical implications of such classification are still not totally clear, especially regarding prognosis. The primary objective of this study was to assess whether the mortality rates were different between four predefined clinical phenotypes.

Patients And Methods: This is a retrospective, observational study carried out at the COPD clinic of a University Hospital.

Cardiovascular Studies in Patients with Chronic Obstructive Pulmonary Disease Due to Biomass Smoke or Tobacco.

Background And Objective: The cardiovascular effects of biomass smoke exposure in patients with chronic obstructive pulmonary disease are not well characterized, and few studies have assessed the possible differences between patients with disease caused by biomass smoke and tobacco. The aim of this study was to search for differences in cardiovascular variables between both types of the disease.

Methods: Twenty subjects (15 men, 5 women) with chronic obstructive pulmonary disease caused by tobacco were matched one to one for sex, age, and forced expiratory volume in 1 s to 20 patients with biomass-related disease.

Octogenarian patients with chronic obstructive pulmonary disease: Characteristics and usefulness of prognostic indexes.

Background And Objective: Most studies on chronic obstructive pulmonary disease (COPD) exclude octogenarian patients. Therefore, the disease is not well characterized in this age group. The objective of this study is to analyze the clinical characteristics of octogenarian patients with COPD and the usefulness of the prognostic indexes used most frequently in this age group.

Differences in systemic inflammation between cigarette and biomass smoke-induced COPD.

Background And Objective: It is known that biomarkers of systemic inflammation are raised in COPD caused by tobacco (T-COPD) compared with healthy controls, but there is less information on the inflammatory status of subjects with COPD caused by biomass smoke (B-COPD). In addition, the possible (if any) differences in inflammation between both types of the disease are still not well known. The aim of this study was to assess the inflammatory profile in B-COPD and T-COPD.

Prevalence of Major Comorbidities in Chronic Obstructive Pulmonary Disease Caused by Biomass Smoke or Tobacco.

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.
