title: Is Chlamydia pneumoniae seropositivity associated with atherothrombotic cerebrovascular infarction?
abstract: OBJECTIVE
  Several studies suggested that Chlamydia pneumoniae (CP) infection may be a risk factor for cerebrovascular disease. Since these studies have reported controversial results, we performed this study to identify whether Cp-immunoglobulin was associated with atherothrombotic cerebrovascular infarction (ACI) in Iranian patients.
  
  
  METHODS
  Forty-five patients admitted with ACI, and 45 control without ACI were enrolled in this case-control study. Using an enzyme-linked immunosorbed assay kit (ELISA), the presence of CP-immunoglobulin (CP-IgG) in studied patient's sera was determined.
  
  
  RESULTS
  The seroprevalence of CP-IgG was 35(77.7%) in the ACI group (mean age=73.3 years) and 29(64.4%) in the control group (mean age=70.1 years) (P>0.05). There was no difference in sex, age, hypertension, smoking, hyperlipidemia, diabetes and obesity between cases and control groups (P>0.05). No association was observed between CP seropositivity and ACI [OR: 1.95 (95% CI, 0.081-2.03), P=0.16].
  
  
  CONCLUSIONS
  Our finding suggests that there is no association between ACI and positive CP-IgG in Iranian patients.
