    Despite its accepted role, a number of controversies persist regarding the use of antibiotics for exacerbations of chronic obstructive pulmonary disease (COPD). The adequate selection of patients, the identification of biomarkers for treatment response, the adequacy to disease and exacerbation severities or the short-term impact on the exacerbation outcome in different settings remain some of the aspects under current debate (1,2). One specific topic that warrants investigation is the potential long-term impact of antibiotic prescription during exacerbations, specifically on the prevention of subsequent exacerbations. The question about whether a specific treatment during the exacerbation can have an impact on the long term preventing future acute episodes is intriguing. Beyond the potential rationale behind, the topic results to be not easy to face, since a number of factors associated with subsequent exacerbations or with re-admissions after an index event are well-known (3). Recently, van Velzen (4) have published a clinical trial to investigate if the antibiotic doxycycline added to the oral corticosteroid prednisolone prolongs time to next exacerbation in patients with COPD receiving treatment for an exacerbation in the outpatient setting. By using a randomized double-blind placebo-controlled design, the authors recruited a cohort of patients with COPD from different outpatient clinics in the Netherlands who were followed-up for 2 years. Bacterial infection may have either a primary or secondary role in about 50% of exacerbations of COPD (Macfarlane 1993, Wilson 1998, Miravitlles 1999, Patel 2002). Haemophilus influenzae, Streptococcous pneumoniae and Moraxella catarrhalis are most commonly involved (Macfarlane 1993, Soler 1998, Murphy 1999). Mycoplasma pneumoniae and Chlamydia pneumoniae have also been reported (Macfarlane 1993, Mogulkoc 1999). A re-examination of data from the placebo arm of a Spanish antibiotic trial that recruited patients with mild to moderate COPD from primary care confirmed that sputum purulence increased the likelihood of treatment failure 6 fold. A CRP elevated greater than 40 mg/L was also independently associated with a 13 fold increase in the risk of treatment failure.(Miravitlles 2013) [evidence level III-2]. El Moussaoui et al (El Moussaoui 2008) conducted a systematic review of 21 randomised controlled trials of antibiotics in exacerbations of chronic bronchitis and COPD. There were similar rates of clinical or bacteriological cure with short courses (≤ 5 days) and longer courses of antibiotics [evidence level I]. A related systematic review (Falagas 2008) found that patients receiving short courses experienced fewer adverse effects than those receiving longer courses.

    In this issue of Lancet Respiratory Medicine, van Velzen and colleagues examined the impact of doxycycline in 301 COPD patients recruited. Chronic obstructive pulmonary disease COPD is a treatable but not curable and largely preventable lung disease. Although some studies have shown that antibiotics reduce symptoms in patients with acute exacerbations of chronic obstructive pulmonary.

    The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. The inflammation is associated with tissue loss and remodelling. Listing a study does not mean it has been evaluated by the U. The investigators hypothesized that doxycycline reduces neutrophilic airway inflammation in patients with 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. Therefore the investigators will conduct a randomized trial of doxycycline in 30 patients. 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.
