Evidence of proatherogenic inflammation in polycystic ovary syndrome
Open accessAbstract
Women with polycystic ovary syndrome (PCOS) have chronic low-level inflammation that can increase the risk of atherogenesis. We measured circulating proatherogenic inflammatory mediators in women with PCOS (8 lean: body mass index, 18-25 kg/m(2); 8 obese: body mass index, 30-40 kg/m(2)) and weight-matched controls (8 lean, 8 obese). Blood samples were obtained fasting and 2 hours after glucose ingestion to measure interleukin-6 (IL-6), soluble intercellular adhesion molecule-1 (sICAM-1), monocyte chemotactic protein-1 (MCP-1), C-reactive protein (CRP), matrix metalloproteinase-2, plasminogen activator inhibitor-1 (PAI-1), and activated nuclear factor kappaB in mononuclear cells. Truncal fat was determined by dual-energy x-ray absorptiometry. Fasting MCP-1 levels were elevated in lean women with PCOS compared with lean controls (159.9 +/- 14.1 vs 121.2 +/- 5.4 pg/mL, P < .02). Hyperglycemia failed to suppress matrix metalloproteinase-2 in lean women with PCOS compared with lean controls (1.7 +/- 1.2 vs -4.8 +/- 1.6 pg/mL, P < .002). Among women with PCOS, obese individuals exhibited higher fasting sICAM-1 (16.1 +/- 0.8 vs 10.5 +/- 1.0 ng/mL, P < .03) and PAI-1 (6.1 +/- 0.7 vs 3.4 +/- 0.8 ng/mL, P < .03) levels. Trend analysis revealed higher (P < .005) IL-6, sICAM-1, CRP, PAI-1, systolic and diastolic blood pressures, triglycerides, fasting insulin, and homeostasis model assessment of insulin resistance index in women with PCOS compared with weight-matched controls, and the highest levels in the obese regardless of PCOS status. Fasting MCP-1 levels correlated with activated nuclear factor kappaB during hyperglycemia (P < .05) and androstenedione (P < .004). Truncal fat correlated with fasting IL-6 (P < .004), sICAM-1 (P < .006), CRP (P < .0009), and PAI-1 (P < .02). We conclude that both PCOS and obesity contribute to a proatherogenic state; but in women with PCOS, abdominal adiposity and hyperandrogenism may exacerbate the risk of atherosclerosis.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
