Τhe incidence of infections due to atypical pathogens (clamydophila pneumoniae, mycoplasma pneumoniae, legionella pneumophila) and bacterial infections in acute exacerbations of chronic obstructive pulmonary disease and their correlation with inflammatory markers and the outcome of the exacerbation
Abstract
The present prospective study was undertaken to determine (a) the predominant bacterial and atypical pathogens in acute exacerbations of chronic obstructive pulmonary disease (COPD) using all three detection approaches ;serology, culture and polymerase chain reaction( PCR), (b) their implications in the inflammatory profile and functional impairment, and (c) the parameters predicting detection of a potentially pathogenic microorganism in sputum cultures.Patients’ data were collected for statistical evaluation. Conventional culture revealed at least one potentially pathogenic microorganism in 52 patients. The most common bacterial pathogens were Haemophilus influenzae (23.9% -22 patients in 17 cases as a single pathogen and 6 cases in combination with other pathogens) and Pseudomonas aeruginosa 14.1%, 13 patients , - in 10 cases as a single pathogen and in three cases in combination with other pathogens).PCR for atypical pathogens was positive in eight patients (five for M. pneumoniae a ...
