Condition

Study Design: Observational Model: Case-Crossover

Primary Outcome Measures:
  • Time to new COPD exacerbation [ Time Frame: One year ] [ Designated as safety issue: No ]
    From discharge of the current hospitalization, the time to a new COPD exacerbation will be estimated. The final aim of this study, descriptive, exploratory and hypothesis-generating, is to obtain a better understanding of the pathobiology of COPD exacerbations to eventually identify clinical correlations (biomarkers) that can help identify and diagnose them more accurately, and guide clinical practice for a more efficient way.


Secondary Outcome Measures:
  • Characterization and severity of pulmonary and systemic inflammation [ Time Frame: One year ] [ Designated as safety issue: No ]
    Describe the biological characterization and severity of pulmonary and systemic inflammation, by means of presence/absence of inflamatory markers, their combination and their concentrations

  • Paired, Individual changes in pulmonary and systemic inflammation [ Time Frame: One year ] [ Designated as safety issue: No ]
    Within individuals, characterization and severity of pulmonary and systemic inflammation, by means of presence/absence of inflamatory markers, their combination and their concentrations

Groups/Cohorts
COPD

COPD patients admitted in any of the participating ECOS hospitals due to a COPD exacerbation.

  1. - External factors. The episodes of COPD exacerbations are associated to exogenous factors (pollution, change of ambient temperature, humidity, infections). The prevalence of environmental contamination and infections is higher than expected.
  2. - Endogenous factors. These factors (hyperinflation, pulmonary embolism, cardiac dysfunction, mucus hypersecretion) are present in a proportion higher than expected
  3. - During exacerbations of COPD serum markers of inflammation and autoimmunity are high relative to baseline in COPD and decrease progressively during the follow-up, after controlling the acute episode

Detailed Description:

Patients will be followed for 12 months. Information to be collected includes clinical, analytical, immunological, microbiological, hemodynamic, imaging, environmental, social and other blood markers of inflammation (IL-8, IL-6, TNF, TNF-alpha, endothelin-1, SLPI, IL10, TGF-beta and markers oxidative stress (TEAC)), and sputum (cell count, IL-6, IL-8, SLPI, ET 1, IL10).

Each center will collect clinical data, blood gas, microbiological and functional data for their patients, which will be centralized through the website of the Red Respira (www.redrespira.net).

A frozen serum sample and another of frozen sputum supernatant will be sent to the coordinating center (Palma de Mallorca).

Statistical analysis will include descriptive statistics: mean, standard deviation and range. Comparison of quantitative variables to be assessed using Student's t-test and ANOVA. Correlations between variables will be performed using bivariate analyzes (Pearson's linear correlation coefficient) and multivariate (multiple regression) analyses, among others.
