  Purpose
Chronic obstructive pulmonary disease (COPD) is a chronic inflammatory disease with high prevalence worldwide and with relevant impact on patient-related quality of life, morbidity and mortality. There is evidence that airway inflammation correlates with the severity of the disease and that airway inflammation is further enhanced during exacerbation. However, it is unknown whether daily fluctuation of symptoms or changes in lung function is paralleled by changes in airway inflammation.

Condition Intervention
Chronic Obstructive Pulmonary Disease Other: COPD treatment

Study Type: Observational
Study Design: Observational Model: Cohort
Time Perspective: Prospective
Official Title: Correlations Between Airway Inflammation, Symptoms and Lung Functions in Patients With Stable Chronic Obstructive Pulmonary Disease (COPD)

Further study details as provided by Alberto Papi, Università degli Studi di Ferrara:

Primary Outcome Measures:
  • Correlation between changes in airway inflammation and symptom score [ Time Frame: 1 month, ]
    Correlation between changes in airway inflammation and symptom score will be evaluated


Secondary Outcome Measures:
  • Correlation between changes in airway inflammation and lung function [ Time Frame: 1 month ]
    Correlation between changes in airway inflammation and lung function will be evaluated

  • Correlations between airway inflammation and symptom scores [ Time Frame: 1 month ]
    Correlation between markers of airway inflammation and symptom score will be performed

  • Correlations between airway inflammation and lung function [ Time Frame: 1 month ]
    Correlation between markers of airway inflammation and lung function will be assessed


Biospecimen Retention:   Samples With DNA
Sputum cells.

Enrollment: 40
Study Start Date: January 2009
Study Completion Date: July 2011
Primary Completion Date: January 2011 (Final data collection date for primary outcome measure)
Groups/Cohorts Assigned Interventions
COPD Other: COPD treatment
Patients, will be asked to continue their previous medication (GOLD guidelines) during the study. No interventional change in COPD treatment will be performed during the study.

Detailed Description:
Patients will undergo a visit every 7 days during one month (5 visits in total). At each visit airway inflammation (exhaled NO, sputum inflammatory cell count) and lung function will be performed. At home patients will be asked to fill a daily diary for symptom assessment.
