title: Glucose ingestion stimulates atherothrombotic inflammation in polycystic ovary syndrome.
abstract: Women with polycystic ovary syndrome (PCOS) have chronic low-grade inflammation that can increase the risk of atherothrombosis. We performed a cross-sectional study to examine the effect of glucose ingestion on markers of atherothrombotic inflammation in mononuclear cells (MNC) of 16 women with PCOS (8 lean, 8 obese) and 16 weight-matched controls. Activator protein-1 (AP-1) activation and the protein content of early growth response-1 (EGR-1), matrix matalloproteinases-2 (MMP2), and tissue factor (TF) were quantified from MNC obtained from blood drawn fasting and 2 h after glucose ingestion. Plasma MMP9 and C-reactive protein (CRP) were measured from fasting blood samples. Truncal fat was determined by DEXA. Lean women with PCOS exhibited greater AP-1 activation and MMP2 protein content after glucose ingestion and higher plasma MMP9 and CRP levels than lean controls. Obese women with PCOS exhibited greater EGR-1 and TF protein content after glucose ingestion, and plasma CRP levels were even higher compared with lean subjects regardless of PCOS status. Truncal fat correlated with MMP9 and CRP levels and glucose-stimulated increases in AP-1 activation and EGR-1 and TF protein content. Testosterone correlated with glucose-stimulated AP-1 activation, and androstenedione correlated with MMP9 and CRP levels and glucose-stimulated AP-1 activation. Thus, both PCOS and obesity contribute to an atherothrombotic state in which excess abdominal adiposity and hyperandrogenism may be specific risk factors for developing atherothrombosis.
