Abstract

Background: Elevated C-reactive protein (CRP) levels due to of heightened vascular inflammatory state in vascular conditions are often associated with elevated interleukin-6 (IL-6) levels since during inflammation CRP production in the liver is induced by IL-6. It has been suggested that CRP may be a predictors of unfavourable outcome in postmenopausal women (PMW) receiving hormone replacement therapy. Because of the possible metabolic effect of hormone replacement therapy (HRT) on CRP, the relative predictive importance of CRP and IL-6 levels in PMW receiving HRT remains to be elucidated. Methods: We measured plasma levels of CRP and IL-6 levels in 346 consecutive PMW (mean age 66±9 years) with cardiovascular risk >20 in 10 years followed during a 36 month period. Women underwent measurement of inflammatory cytokines at baseline and were allocated to two groups according to the willingness to take hormone replacement therapy. All women underwent a further measurement of CRP and IL-6 at 3 and 6 months. Health status was assessed by out patient visits and hospital charts. Results: During 1 year follow up, three patient died, four had a major cardiovascular event, three had a unstable angina, two had a transient ischemic attack and two patients underwent PTCA. PMW with events had higher CRP levels compared with patients with no events (1.94±0.61 versus 1.43±0.21, P
