Relationship between dyslipidemia C-Reactive Protein and serological evidence of chlamydia pneumoniae in Turkish patients with coronary artery diseases

Abstract

Relationship between dyslipidemia C-Reactive Protein (CRP) and serological evidence of Chlamydia pneumoniae was investigated in a Turkish population with coronary artery disease. This prospective randomized blinded study was carried out in Florence Nightingale Hospital which is affiliated to Kadir Has University Medical Faculty. Thirty-two patients with acute coronary artery diseases (ACAD) 32 patients with chronic coronary artery diseases (CCAD) and 26 healthy controls (HC) were included in the study We detected serum concentrations of C. pneumoniae IgG IgA and IgM by ELISA method. We measured total cholesterol trigliseride LDL and HDL- cholesterol levels to determine dyslipidemia which was defined as total cholesterol >200 mg/dL trigliserid > 150 Mg/dL LDL >130 mg/dL HDL <45 mg/dL. CRP levels were also measured. Seropositivity to C. pneumoniae IgG was 84.3% 100% and 65.3%

seropositivity to IgA was 9.3% 6.2% and 3.8%

and seropositivity to IgM was 12.5% 15.3% and 15.4% in patients with ACAD CCAD and HC respectively. Dyslipidemia was found as 93.7% 78.1% and 0% of patients with ACAD CCAD and HC respectively. CRP level was high in all patients (ACAD CCAD) but not in healthy controls. As a conclusion we found a significant association between seropositivity to C. pneumoniae IgG and dyslipidemia and CRP levels in ACAD and CCAD patients (p<0.05). C. pneumoniae IgG antibodies should he evaluated together with serum lipids and CRP levels in patients with ACAD and CCAD in Turkish population. This may help clinicians in treatment of C. pneumoniae infection and decrease the risk of coronary artery diseases.
