INTRODUCTION. Several infectious agents have been found to be involved in atherogenesis over the past decade. Chlamydia pneumoniae is one of the commonest associated agents. In this study we have analysed the possible relationship between a high level of antibodies to Chlamydia, and the presence of carotid ultrasound changes in patients who have had strokes. PATIENTS AND METHODS. We studied 230 patients admitted consecutively to the Stroke Unit in our hospital, with the diagnosis of stroke. All the patients in the group had carotid duplex ultrasound studies to assess the degree of stenosis. All these patients also had serological studies using micro-immunofluorescence to detect antibodies to Chlamydia pneumoniae. RESULTS. Only 35 patients were found to have positive Chlamydia pneumoniae serology. The degree of atheromatosis was similar in the patients with high levels of IgG for Chlamydia pneumoniae and in those with normal serology. There was no statistically significant relation between the degree of stenosis and being seropositive for Chlamydiae. CONCLUSIONS. Our findings suggest that in an unselected population of stroke patients there is no relations between carotid atheromatosis and positive serology findings to Chlamydia pneumoniae. If there is any relationship between Chlamydia pneumoniae and carotid atheromatosis, serology does not seem to be a technique which is suitable for its assessment.
