NCT05342558
This is a randomized, blinded, controlled clinical trial for mexican COPD patients. Biomass smoke associated COPD (BS-COPD) clinical spectrum is different to the one seen in tobacco smoke associated COPD (TS-COPD). BS-COPD patients present COPD-asthma phenotype or asthma-COPD overlap syndrome (ACOS), TS-COPD patients present mostly the emphysema phenotype. BS-COPD patients have a greater risk of exacerbations in comparison to the emphysema phenotype. Therefore, individualizing treatment in both phenotypes may be very useful among the clinical practitioners. The investigators expect treatment with FF/V to be superior in preventing COPD exacerbations than the U/V combination in patients with COPD-asthma phenotype; andU/V to be superior than FF/V in patients with the emphysema phenotype. The general objective of the study is to determine the exacerbations outcome in patients with COPD-asthma vs emphysema phenotype patients, treated with both drugs. Secondary objectives include assessment of pulmonary function tests, quality of life, dyspnea and functional capacity change after a 24 weeks treatment.

Cardiovascular and respiratory diseases are the first and third cause of death, respectively. Cardiovascular risk is known to increase in groups with impaired lung function; however, the mechanisms behind this association are not fully understood. The aim of CaReS is to elucidate the shared pathophysiology of impaired lung function and cardiovascular risk, and to investigate the risk factors associated with them. The CaReS Cohort Study includes adults (18-80 years old) from Cartagena de Indias, a tropical city on Colombian Caribbean Coast, where recent population admixture settled a three-hybrid genetic structure (European, African and Ameridian ancestry). At baseline, the cohort will generate extensive data on -omics (e.g., genomics, transcriptomics, metabolomics, and epigenomics), socio-economic wellbeing, lifestyle, medical history, cardiometabolic, inflammatory and liver function markers, as well as objective measures of ventilatory and cardiovascular performance. The cohort will collect data every three years, for a total period of ten years. Prospective risk of cardiovascular disease and chronic obstructive pulmonary disease (COPD) will be investigated, and their risk factors. Throughout the study period, changes in prevalence, and interactions of various risk factors with these changes will also be ascertained. A predictive risk score for cardiovascular and chronic respiratory disability will be built, using cross-sectional and longitudinal data.
