Evaluation of Pathogenetic Mechanisms of Chronic Obstructive Pulmonary Diseases
Studienübersicht
Status
Intervention / Behandlung
Detaillierte Beschreibung
Objectives:
To evaluate the patterns of pathophysiology and genetic predisposition of COPD and asthma
Tasks:
To evaluate patients that respond to corticosteroids and those who do not
Compare the inflammatory markers:
- of COPD and asthma patients before and after treatment with inhaled glucocorticoids
- of COPD and asthma patients that respond to inhaled glucocorticoids and those who do not
- of nonsmokers and smokers asthma patients
To identify a small set of markers that can be used to predict corticosteroid-treatment response in patients with COPD.
To evaluate epigenetic factors
To compare gene mutation and polymorphism between study groups
To evaluate the relationship between genetic predisposition and pathophysiology, clinical symptoms
To evaluate the relationship between patterns of pathophysiology and clinical symptoms, lung function, quality of life in patients with chronic obstructive pulmonary diseases.

Beschreibung
Inclusion Criteria:
- Male or female outpatients aged 40-80 years inclusive.
- An established clinical history of COPD as defined by the GOLD guidelines.
- COPD patients with a baseline (pre-bronchodilator) FEV1 40-80% of predicted normal value; post-bronchodilator FEV1/FVC ratio ≤ 70% predicted.
- COPD patients with a smoking history (current or ex-smoker) of ≥10 pack years or those who have exposure to occupational dust and chemicals
- An established clinical history of asthma defined by the GINA recommendations.
- Subjects with out hypoxemia (all subjects must have an O2 saturation ≥88% on room air).
Control (healthy) subjects with baseline FEV1 >80% of predicted normal value
- A female is eligible to participate this study if she is of non-childbearing potential, or childbearing potential has a negative pregnancy test.
