Coxiella burnetii seropositivity and coronary ectasia
Özet
Bacterial infections could contribute to atherosclerotic inflammation. We investigated the association of Coxiella Burnetii seropositivity with the atherosclerotic lesion types (obstructive and/or ectatic), serum lipid profile, nitric oxide (NO),total sulfhydryl (SH) groups and malonyldialdehyde (MDA) levels. A total of 150 participants (73 male, mean age: 56.6 ± 11.4 years; 77 female, mean age: 57.3 ± 13.0 years) were enrolled into the study. Coronary angiography was performed all the participants. We also performed serum lipid profile, NO, SH groups and MDA levels to determine the changes in chronic and acute Coxiella burnetii infections. The patients with obstructive and ectatic coronary artery lesions were of higher Coxiella phase I IgG titer (The marker of chronic Coxiella infection) than those of other coronary artery disease groups(One Way ANOVA, p=0.001). There were higher serum total cholesterol levels in the patients with chronic Coxiella infection than those of other patients. The chronic Coxiella Burnetii infection may be an important factor for the formation of coronary artery ectasia on basement of atherosclerotic coronary artery disease. Hyperlipidemia might also facilitate and augment this association.
