[Influence of Chlamydia pneumoniae and cytomegalovirus infections on prevalence and the course of coronary artery disease].
Chlamydia pneumoniae (C. pneumoniae) as well as cytomegalovirus (CMV) are common pathogens found in about 50% of healthy western population. Many studies suggest a role of C. pneumoniae in development of coronary artery disease (CAD). CMV infection is also considered to increase risk of developing of CAD as well as restenosis after percutaneous coronary revascularization (PCI). The aim of our study was to evaluate a possible role of C. pneumoniae and CMV infections in both CAD development and course in patients (pts) undergoing PTCA. We enrolled 105 pts (mean age 56.4 years, 83 males) with angiographically documented CAD. Control group consisted of 63 healthy controls (mean age 47.25 years; 31 males). The study subjects were evaluated for presence of C. pneumoniae specific IgG antibodies (MIF test--MRL Diagnostic, USA; seroprevalence assumed when titre > or = 1/8). In 58 random PCI pts CMV specific IgG antibodies (ELISA Eti-Cytok-G PLUS--Dia Sorin) were evaluated. Pts were sampled at the time of PTCA. All PCI pts were assessed by angina questionnaire 5.9 +/- 2.6 months (mo) after the procedure with respect to clinical restenosis. C. pneumoniae IgG antibodies were detected in 37.1% of pts and in 22% of healthy controls (p < 0.05). After logistic regression was applied trend towards more frequent occurrence of C. pneumoniae specific IgG in CAD pts was shown (p = 0.10 OR = 2.4; 95% CI: 0.8-6.8). No significant correlation was found between anti-C. pneumoniae IgG presence or anti-CMV IgG titre and coronary atherosclerosis advancement. There was no significant difference in anti-CMV IgG titre between 9 pts who developed clinical restenosis 5.9 +/- 2.6 mo after PCI and the remaining pts. Our study results suggest a possible significant correlation between C. pneumoniae with CAD prevalence. We did not find a positive association of either infection markers with coronary atherosclerosis advancement. We did not find correlation of clinical restenosis after PCI with markers of CMV infection.
