Prophylactic Antibiotic Treatment of Patients With Chronic Obstructive Lung Disease (COLD)
Study Details
Study Description
Brief Summary
The purpose of the study is to investigate, in patients with moderate to severe chronic obstructive lung disease, whether intermittent antibiotic treatment leads to:
-
A slower rate of decline in forced expiratory volume in one second (FEV1);
-
A reduction in the frequency and severity of exacerbations;
-
Fewer hospital admissions for chronic obstructive pulmonary disease (COPD);
-
Lower mortality;
-
An improved quality of life as compared to a group of placebo treated patients.

Eligibility Criteria
Criteria
Inclusion Criteria:
-
Patients above 50 years of age, with a current admission for exacerbation of COLD or at least one admission within the previous two years.
-
Current or ex-smoker
-
Postbronchodilator FEV1 < 60% in stable condition (> 4 weeks after hospitalisation)
-
< 300 ml bronchodilator reversibility in FEV1
Exclusion Criteria:
-
Patients with end-stage COLD, who are not expected to survive for 3 years (typically bedridden patients being dyspnoeic in rest).
-
Patients with known other respiratory tract infection, e.g. tuberculosis or aspergillosis, in whom the intervention is known to be inefficient.
-
Patients with pulmonary malignancy
-
Patients with other pulmonary diseases than COLD.
-
Patients with immunodeficiency. However, COLD patients treated with steroids can be included.
-
Patients with known hereditary disposition to lung infections such as alfa-1-antitrypsin deficiency, cystic fibrosis or primary ciliary dyskinesia.
-
Patients receiving longterm antibiotic treatment ( e.g. recurrent cystitis).
-
Patients with known allergy or intolerance to azithromycin
-
Pregnant or breastfeeding women
-
Manifest heart, liver or renal insufficiency
-
Patients that, for reasons not stated above, are unlikely to be able to participate in a study period of 3 years.
