AIMS This study aimed to determine the prevalence of chronic obstructive pulmonary disease (COPD) in Spain and identify the level of undiagnosed disease and its impact on health-related quality of life (HRQL) and activities of daily living (ADL). METHODS A population-based sample of 4274 adults aged 40-80 years was surveyed. They were invited to answer a(More)
BACKGROUND Elevated circulating levels of several inflammatory biomarkers have been described in selected patient populations with COPD, although less is known about their population-based distribution. The aims of this study were to compare the levels of several systemic biomarkers between stable COPD patients and healthy subjects from a population-based(More)
The aim of this prospective observational study was to determine those factors influencing bacterial colonization in patients with stable chronic obstructive pulmonary disease (COPD). Eighty-eight outpatients with stable COPD and 20 patients with normal spirometry and chest radiography (controls) had a fibreoptic bronchoscopy performed with topical aerosol(More)
The aim of the study was to obtain the general population norms for the St. George's Respiratory Questionnaire (SGRQ), a specific questionnaire for respiratory diseases. The IBERPOC project was a cross-sectional study of representative samples of the general population aged between 40-69 yrs. The study sample was composed of 862 individuals. All(More)
BACKGROUND Patients with COPD may share some clinical characteristics with asthma sufferers. This phenotypic overlap between COPD and asthma is not yet well characterised. METHOD We have analysed data from the EPI-SCAN study, an epidemiological, population-based study in Spain that included 3885 (40 to 80-year-old) subjects in order to investigate the(More)
BACKGROUND Proinflammatory leukotrienes, which are not completely inhibited by inhaled corticosteroids, may contribute to asthmatic problems [corrected]. A 16 week multicentre, randomised, double blind, controlled study was undertaken to study the efficacy of adding oral montelukast, a leukotriene receptor antagonist, to a constant dose of inhaled(More)
BACKGROUND AND OBJECTIVES Chronic obstructive pulmonary disease (COPD) causes considerable morbidity and mortality in Spain. The 1997 IBERPOC study, applying the old criteria of the European Respiratory Society, reported a COPD prevalence of 9.1% in the adult population of Spain. The Epidemiologic Study of COPD in Spain (EPI-SCAN) aims to determine the(More)
Prior antibiotic therapy, size of the infiltrate, and the person who performed the technique were the three factors that we studied to assess their influence on the effectiveness of transthoracic needle aspiration (TNA). Ninety-one patients with a diagnosis of severe bacterial pneumonia, who underwent TNA, have been included in the study. The technique was(More)
OBJECTIVE To ascertain the differences in smoking characteristics between a group of smokers with COPD and another group of healthy smokers, both of which were identified in a population-based epidemiologic study. DESIGN AND PARTICIPANTS This is an epidemiologic, multicenter, population-based study conducted in seven areas of SPAIN: A total of 4,035(More)
OBJECTIVE In the studies carried out to date, the cost of chronic obstructive pulmonary disease (COPD) may have been overestimated due to the inclusion of previously diagnosed patients seeking medical attention for their symptoms. As a result, the severity of the cases included in these studies may have been greater than in an unselected sample of the(More)
