SAN DIEGO -- Young women with polycystic ovary syndrome have evidence of endothelial dysfunction and low-grade, chronic inflammatory markers characteristic of much older patients, researchers reported at the annual meeting of the Endocrine Society.
Evanthia Diamanti-Kandarakis, M.D., and associates at Laiko Hospital of the University of Athens compared endothelial function and inflammatory cytokines in 25 women with PCOS and 20 age-matched controls with similar body mass index (BMI) measurements and waist-hip ratios. The women were in their mid to late 20s and had BMIs of about 26-29 kg/[m.sup.2].
Endothelial function was determined by flow-mediated dilatation of the brachial artery on ultrasound, plus endothelin-1 (ET-1) plasma levels. Numerous cytokines were measured in blood to assess arterial inflammation.
Subjects with PCOS had significantly lower percentages of flow-mediated dilatation than controls (3.47% vs. 9.26%). Nitrate-induced dilatation, measured to exclude smooth muscle cell injury, was not significantly different in the two groups. Significantly higher levels of ET-1, intracellular adhesion ...
