Abstract/OtherAbstract:
Striking evidence indicates endothelial impairment in polycystic ovary syndrome (PCOS) but the mechanisms linking PCOS status to cardiovascular risk remain elusive. Platelet/endothelial cell adhesion molecule (PECAM)-1 is a soluble (s) signaling molecule involved in inflammation and angiogenesis with predictive value for endothelial dysfunction in patients at risk. In a prospective, controlled study, sPECAM-1 levels and the relationships to metabolic, inflammatory and vascular PCOS traits were evaluated in 26 patients and 29-age- and body mass index-matched controls. To assess endothelial injury, carotid artery intimae-media thickness (CIMT) and brachial artery flow-mediated vasodilatation (FMD) were employed. Of the 26 women with PCOS, 25 completed a six-month metformin combined with ethinylestradiol 0.3 mg/drospirenone 3 mg therapy. Soluble PECAM-1 levels were increased in PCOS (p = 0.018 vs. Controls) and significantly decreased at follow-up (p = 0.0002). Smoking and weight had no effect on sPECAM-1 dynamics. In both univariate and multivariate analysis, basal sPECAM-1 was inversely related to FMD (r = -0.311, p = 0.021) but not CIMT. To conclude, sPECAM-1 is increased in PCOS, an effect reversed by combined metformin and anti-androgenic contraceptive therapy. Elevated sPECAM-1 contributes to endothelial dysfunction however further studies are inquired to assess its relevance as biomarker and potential therapeutic target in PCOS.
