  1. Chlamydia pneumoniae and acute myocardial infarction in Jerusalem.

    Article - En anglais

    Background

    A number of studies in European and North American populations have reported associations between Chlamydia pneumoniae seropositivity and coronary heart disease (CHD).

    Our objective was to assess the association of IgG and IgA antibodies to C. pneumoniae with acute myocardial infarction (MI) in a population-based case-control study in a Middle Eastern country.

    Methods

    Eligible cases aged 25-64 with a first acute Ml were ascertained through an active surveillance system in Jerusalem hospitals between 1987 and 1989 (85% response).

    Controls were Jerusalem residents aged 25-64 sampled from the national population registry (83% response).

    Data on sociodemographic variables, CHD history and risk factors were collected by interview.

    Chlamydia serology, available for 93% of eligible participants, was performed by microimmunofluorescence on frozen stored samples using the TWAR antigen.

    Altogether, 251 male and 51 female cases, and 324 male and 162 female controls were analysed.

    Results

    Overall, high IgG titres (=128) were not associated with increased risk of acute Ml (Odds ratio [OR]=0.74 for men [95% confidence interval (Cl) : 0.47-1.17] and 0.91 for women [95% Cl : 0.43-1.94]) ; neither were high IgA titres (=80) (OR=1.11 for men [95% Cl : 0.71-1.73] and 1.15 for women [95% Cl : 0.33-4.0]). At IgG and IgA titres of>32 and>20 respectively there was also no relation.

    Conclusions

    An association of C. (...)
