Abstract

Mycoplasma pneumoniae and Chlamydia pneumoniae have been suggested to take part in the acute exacerbation of bronchial asthma and chronic obstructive pulmonary disease (COPD). Several studies have questioned whether they may play pathogenic roles in connection with bronchial asthma and COPD. This study was designed to evaluate the seroprevalences of M. pneumoniae and C. pneumoniae in stable asthma and COPD patients, and to compare with control patients. The medical records of one hundred forty patients who underwent M. pneumoniae and C. pneumoniae serology were retrospectively reviewed. Seroprevalences of M. pneumoniae and C. pneumoniae in the asthma group (11.1% and 8.3%, respectively) were higher than in the control group (4.4% and 2.2%, respectively) without statistical significance. The seroprevalence of M. pneumoniae in the COPD group (16.9%) was significantly higher than in the control group, and the seroprevalence of C. pneumoniae in the COPD group (3.4%) was higher than in the control group without statistical significance. This study raises important questions about the relation of M. pneumoniae and C. pneumoniae infection with stable asthma or COPD.
