Distrubition of etiologic agents in community acquired pneumonia patients

Community-acquired pneumonia (CAP) is still most common and severe health problem because of having high mortality and morbidity and responsible for important part of deaths cause form infections. There is no study that explain typically and atypically etiologic agents that having role in being CAP in our country. About this, there is no significant concordance between etiologic agents that cause CAP in Turkey and foreing countries. Our aim is systematically determinate the distrubition and frequancy of infection agents and explain the factors that cause pneumonia in patients who attend to hospital and diagnosed CAP. In our one year prospective study we enrolled 96 patiens in to study. We applied noninvazive diagnostic procedures for microbiological diagnose standartly to all patients. The general characteristics of patients studied on 96 patients altough microbiological results was determined on 72 patients who all diagnostic tests could applied. We described etiologic diagnose in 56 (77.8%) of 72 patients. Most common infective agents were viruses (57.1%). Altough we determined other atypically and bacterial agents that cause mixt infections with viral agents in 48.2%. In viral agents the rate of CAP with one pathogen was 17%. In these pathogens the most common identified agent was Influenza A virus (6.9%). The second most common pneumonia cause was C. pneumoniae (28.6%) and the third agent was M. pneumoniae in 25.0%. S. pneumoniae was in fourth etiologic infective agent with 10.7% rate and H. influenzae and M. catarrhalis were fifth most common etiologic agents (7.1%). Both these agents were shown in mixt infections with viruses in 50.0% rate. L. pneumophila was found 1.8% in our study. P. aeruginosa (3.6%) and S. aureus (1.8%) were deteterminated more less etiologic agents. Our mortality rate was 10.4%. This study is the first study that investigate distrubition of CAP causes systematically in Turkey. Our data is similar with literature. These results are support 63Turkish Thorasic Society diagnose and treatment guidelines that prepared based on national and international literatures and using in Turkey.
