However, as women grow older, especially after menopause the incidence of atherosclerosis and heart disease increases. These findings suggest that estrogen may be protective and help in preventing heart disease.\n\nStudies of large groups of post-menopausal women suggest that hormone replacement therapy (therapy that includes estrogen) reduces the risk of heart disease. Estrogen causes favorable changes in particles that carry cholesterol in the blood stream and improves function of blood vessels. Estrogen may also stimulate the immune system's ability to fight off infections that may lead to or contribute to atherosclerosis.\n\nResearchers believe two specific infectious agents (Chlamydia pneumoniae and human cytomegalovirus) may cause damage to the lining of blood vessels resulting in inflammation and the development of atherosclerosis.\n\nThe purpose of this study is to determine if estrogen treatment can change how the immune system responds to chronic infections, by Chlamydia pneumoniae and human cytomegalovirus, in postmenopausal women.", "DetailedDescription"=>"The incidence of atherosclerotic cardiovascular disease in women does not approach rates seen in men until approximately a decade following menopause, suggesting that estrogen is vasculoprotective. Infectious pathogens such a Chlamydia pneumoniae (C. pneumoniae) and human cytomegalovirus (hCMV) have been implicated in the pathogenesis of atherosclerosis. Experimental studies in cultured lymphocytes and animals suggest that estrogen stimulates cell-mediated immune responsiveness, observations that are potentially relevant to the eradication of intracellular pathogens including C. pneumoniae and hCMV. The purpose of this study is to determine whether estrogen therapy augments cell-mediated immune responsiveness in estrogen-deficient postmenopausal women who have serologic evidence of chronic infection with C. pneumoniae and/or hCMV. A comparison will be made between seropositive and seronegative women. We propose that estrogen therapy will stimulate a more efficient cell-mediated response to these chronically persistent infectious intracellular pathogens, resulting in eradication of these organisms that are of potential importance in atherogenesis."}, "EligibilityModule"=>{"Gender"=>"Female", "StdAgeList"=>{"StdAge"=>["Child", "Adult", "Older Adult"]}, "HealthyVolunteers"=>"No", "EligibilityCriteria"=>"Must be a postmenopausal woman 65 years of age or younger.\n\nTime since last date of menses should be at least 12 months, with plasma estradiol less than 50 pg/ml and FSH greater than 50 pg/ml.\n\nWomen must be without clinical evidence of CAD as determined by history, cardiovascular physical examination, and EKG.\n\nMust not have used hormone replacement therapy within past 6 months.\n\nMust not have used dietary supplements and any medication (over-the-counter or prescribed) within 1 month.
