[Prevalence and characteristics of chronic obstructive pulmonary disease in non-smokers].

Objective: The objective of the study was to know the profile of patients diagnosed with chronic obstructive pulmonary disease (COPD) and who have never been smokers.

Design: A transversal study.

Location: Primary Care Centre of Pla d'Urgell (Primary care setting in Lleida, Spain).

Prevalence of chronic obstructive pulmonary disease (COPD) not diagnosed in a population with cardiovascular risk factors.

Background And Objective: The magnitude of undiagnosed COPD in our population with cardiovascular risk factors (CVRF) is unknown. The objective of this study was to estimate the prevalence of undiagnosed COPD and its specific characteristics in a population with CVRF.

Materials And Methods: Study the prevalence of COPD in patients with CVRF.

Correlation between tuberculin skin test and IGRAs with risk factors for the spread of infection in close contacts with sputum smear positive in pulmonary tuberculosis.

Background: The aim of the study was to assess the correlation between the tuberculin skin test (TST) and in vitro interferon-gamma released assays (IGRAs) with risk factors for the spread of infection in smear positive pulmonary tuberculosis (TB) contacts.

Methods: We recruited prospective contacts with smear positive pulmonary TB cases. We looked at human immunodeficiency virus (HIV) infection and other conditions of immunosuppression, presence of BCG vaccination and the degree of exposure to the index case.
