    Abstract:
    Chlamydia pneumoniae infection has been often associated with several chronic diseases including asthma and chronic obstructive pulmonary diseases (COPD). The spectrum of Chlamydia pneumoniae infection has been expanded to the association with coronary heart disease (CHD). In Morocco, the implication of Chlamydia pneumoniae infection in these pathologies is unknown. The aim of our study was to determine the relationship between infection with Chlamydia pneumoniae and respiratory pathology and atherosclerosis. The patients were from two departments (department of respiratory disease and of cardiology), and presented exacerbation of COPD and asthma or atherosclerosis. The mean age was 45 years a with a 1.7 sex ratio for the first population and 61 years with a 1.4 sex ratio for the second population. Serological diagnosis of Chlamydia pneumoniae infection has been determined by microimmunofluorescence (MIF). All samples were tested for anti-Chlamydia pneumoniae IgG, IgA and IgM. In the first group, we found 42 % positive for IgG, 11 % for IgA, and no case for IgM. In the second group the presence of anti-Chlamydia pneumoniae IgG was observed in 67.5 % cases, IgA in 16.5 % cases and IgM in 2 % cases, 14 % of patients had negative serology for IgA, IgG, and IgM. Our results are in accord to those reported by other studies. According to these results, it seems that a certain degree of association exists between Chlamydia pneumoniae infection and exacerbation of COPD, asthma and atherosclerosis which should be of importance on a therapeutic point of view.
