COPD is a disease characterized by chronic inflammation and irreversible airway obstruction. Chronic inflammation lead to degradation of extracellular matrix and hereby destruction of lung parenchyma. Tetracyclines are known for their anti-inflammatory properties in diseases such as rheumatoid arthritis.
To assess the effect of doxycycline on markers of neutrophilic inflammation and proteolytic activity in induced sputum of stable GOLD II and III COPD patients.
Thirty patients with stable GOLD II COPD.
Placebo versus doxycycline in randomised design.
