Chronic obstructive pulmonary disease (COPD) is one of the leading causes of morbidity and mortality worldwide. By 2030, COPD is expected to be the fourth main cause of death. Community-acquired pneumonia (CAP) represents not only a frequent complication but also a deadly cause in COPD patients. Inhaled corticosteroids, which are frequently used among COPD patients increase the risk for pneumonia. The effect of pneumococcal conjugate vaccine 13 (PCV13) on the prevention of pneumococcal pneumonia among COPD patients in Korean population has not been studied yet. Several factors such as multi-lobar pneumonia, Pseudomonas aeruginosa pneumonia, and high pneumonia severity are related to poor outcome of patients with COPD and pneumonia. Prior pneumococcal vaccine has a beneficial effect on outcomes of pneumonia with COPD patients. However, the effects of pneumococcal vaccine on the clinical outcome of COPD patients were evaluated mainly on 23-valent pneumococcal polysaccharide vaccine (PPV23). The beneficial effects of PPV23 rapidly fade out after inoculation, which is more prominent in old age group. In this sense, PPV23 vaccine is not sufficient in preventing pneumococcal diseases in COPD patients because COPD is the disease of old ages and mortality rate increases exponentially with advancing age. Pneumococcal conjugate vaccine 13 (PCV13) can overcome the waning phenomenon by the production of memory B cells. Although PCV13 is expected to be the best option for the prevention of pneumococcal pneumonia in COPD patients, there are few available studies supporting it. In this study, we will conduct prospective, multi-center trial with the collaboration of Korean pulmonologists in five university-affiliated hospitals. In this study, we will evaluate influenza and pneumococcal vaccination status, the pathogen distribution, pneumonia severity, and clinical outcomes of hospitalized pneumonia patients with COPD. If successfully accomplished, this study will enhance the awareness of the preventive use of PCV13 in COPD patients among Korean pulmonologists and, most importantly, it will lead to protection of more COPD patients from pneumococcal pneumonia, one of the most frequent and deadly complication.
