Doxycycline and Airway Inflammation in Chronic Obstructive Pulmonary Disease (COPD)

March 5, 2009 updated by: Medical Center Alkmaar

Doxycycline and Airway Inflammation in COPD: A Randomised Placebo Controlled Trial Studying the Effects of Doxycycline on Airway Inflammation in Patients With Moderate and Severe Stable COPD.

COPD is a progressive pulmonary disease that is characterized by an inflammatory process in the airways and the lungs which leads to progressive airway obstruction. The inflammation is associated with tissue loss and remodelling. The investigators hypothesized that doxycycline reduces neutrophilic airway inflammation in patients with COPD. Therefore the investigators will conduct a randomized trial of doxycycline in 30 patients.

Study Overview

Detailed Description

Rationale:

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.

Objective:

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.

Study population:

Thirty patients with stable GOLD II COPD.

Intervention:

Placebo versus doxycycline in randomised design.

Description

Inclusion Criteria:

  • GOLD II or III COPD (GOLD II: FEV1/FVC < 70%; 50% < FEV1 < 80% predicted, GOLD III: FEV1/FVC < 70%; 30% < FEV1 < 50% predicted ).

  • Allergy for tetracyclines or a history of substantial side-effects.
  • Active respiratory diseases other than COPD (e.g. sarcoidosis, tuberculosis, lung cancer, bronchiectasis).
  • Acute exacerbation of COPD as defined by Anthonisen et al. [10].
  • Signs and/or symptoms of a current respiratory or non-respiratory infection.
  • Use of oral or intravenous corticosteroids or other immunosuppressive drugs within the last month.
