The role of bronchoscopy in patients with SARS-CoV-2 pneumonia.

Background: The role of bronchoscopy in coronavirus disease 2019 (COVID-19) is a matter of debate.

Patients And Methods: This observational multicentre study aimed to analyse the prognostic impact of bronchoscopic findings in a consecutive cohort of patients with suspected or confirmed COVID-19. Patients were enrolled at 17 hospitals from February to June 2020.

Clinical characteristics and outcomes among hospitalized adults with severe COVID-19 admitted to a tertiary medical center and receiving antiviral, antimalarials, glucocorticoids, or immunomodulation with tocilizumab or cyclosporine: A retrospective observational study (COQUIMA cohort).

Background: The COVID-19 outbreak challenges the Spanish health system since March 2020. Some available therapies (antimalarials, antivirals, biological agents) were grounded on clinical case observations or basic science data. The aim of this study is to describe the characteristics and impact of different therapies on clinical outcomes in a cohort of severe COVID-19 patients.

Comorbidity in chronic obstructive pulmonary disease. Related to disease severity?

Background And Objective: Several diseases commonly co-exist with chronic obstructive pulmonary disease (COPD), especially in elderly patients. This study aimed to investigate whether there is an association between COPD severity and the frequency of comorbidities in stable COPD patients.

Patients And Methods: In this multicenter, cross-sectional study, patients with spirometric diagnosis of COPD attended to by internal medicine departments throughout Spain were consecutively recruited by 225 internal medicine specialists.

Prevalence of anaemia associated with chronic obstructive pulmonary disease. Study of associated variables.

Background: Anaemia is one of the extrapulmonary manifestations of chronic obstructive pulmonary disease (COPD). Its real prevalence, physiopathology and clinical repercussion are unknown. The objectives of our study were: to determine the prevalence of anaemia in patients with stable COPD not attributable to other causes and to establish the relationship of anaemia with clinical, prognostic and inflammatory markers with an important role in COPD.

[Prognosis following acute exacerbation of COPD treated with non-invasive mechanical ventilation].

Introduction: Patients with chronic obstructive pulmonary disease (COPD) who survived an acute exacerbation with acute respiratory failure that required non-invasive mechanical ventilation (NIMV) are a group with a poor medium-term prognosis.

Objective: To identify re-admission and mortality rates within one year from discharge and to analyse factors associated with both events in a consecutive series of COPD patients treated with NIMV.

Methods: A cohort of 93 COPD patients who survived an acute exacerbation and who required NIMV was followed up after discharge.
