Abstract
Objective: To determine the relationship between severity of the acute exacerbation of chronic obstructive pulmonary disease (COPD) patients with blood and sputum cultures. Material-Method: Blood and sputum samples were collected from 139 acute exacerbations of COPD patients. Samples were seeded in to eosin methylene blue and bloody-agar medium. Spirometry results compared with developed bacteria. Results: Patients were classified according to the Global Initiative for Chronic Obstructive Lung Disease as stage 1, 2, 3 and 4 on the basis of pulmonary function test (PFT). Bacteria produced in sputum and blood cultures were classified into 4 groups. Bacteria classification were defined as; group 1: no production or non-pathogen bacteria, group 2: S. pneumoniae and other gram positive cocci, group 3; M. catarrhalis, group 4: Enterobactericaceae and Pseudomonas spp. PFT values of patients were compared with bacteria obtained from sputum and blood culture. 39/139 patients pathogenic bacteria in sputum cultures were produced. The amount of pathogen bacteria produced in stage 3 and 4 patients was significantly higher than stage 1 and 2 patients. Conclusions: Correlation detected between deterioration of lung function and bacteria isolated from patients with exacerbations of COPD. In acute exacerbations Enterobactericaceae are the dominant group
