Objective: To evaluate the effects of a pill with drospirenone (3 mg) plus ethinyl E(2) (20 μg) (DRP/20EE) alone or associated with metformin or cyproterone acetate (CPA) on some metabolic cardiovascular risk factors in women with polycystic ovary syndrome (PCOS)., Design: Randomized, open-label clinical trial., Setting: Academic medical clinic., Patient(s): Forty-eight hirsute women with PCOS., Intervention(s): Patients were randomized to treatment with DRP/20EE or with DRP/20EE plus metformin (1,500 mg/d) or with DRP/20EE plus CPA (12.5 mg/d, 10 days per cycle) for 6 months., Main Outcome Measure(s): Blood pressure, lipid profile, and indexes of glucose tolerance and insulin sensitivity were assessed before and after 6 months of treatment., Result(s): Body mass index and blood pressure were not modified by any treatment. Treatment with DRP/EE20 did not change the lipid profile; DRP/EE20 plus metformin significantly increased high-density lipoprotein cholesterol concentrations; DRP/EE20 plus CPA significantly increased triglycerides and total cholesterol. The area under the curve for insulin was significantly decreased by DRP/EE20 and DRP/EE20 plus metformin, but it was significantly increased by DRP/EE20 plus CPA. Treatment with DRP/EE20 plus CPA significantly increased the homeostasis model assessment of insulin resistance index and significantly reduced the glucose to insulin ratio index. Treatment with DRP/EE20 significantly increased the glucose to insulin ratio index., Conclusion(s): Treatment with DRP/EE20 improved insulin sensitivity in hirsute women with PCOS, with no deterioration of lipid profile. This effect was not ameliorated by the addition of metformin. The positive metabolic effects of DRP are abolished by the concomitant use of CPA., (Copyright © 2010 American Society for Reproductive Medicine. Published by Elsevier Inc. All rights reserved.)

Objective: To evaluate the metabolic profiles of adolescents with different phenotypes of polycystic ovary syndrome (PCOS)., Design: Observational study., Setting: University outpatient clinic., Patient(s): Adolescents with PCOS (n = 120) were divided into four groups: oligomenorrhea and hirsutism (O-H, n = 50), oligomenorrhea, hirsutism, and polycystic ovaries (PCO-O-H, n = 22), oligomenorrhea, hirsutism, and hyperandrogenemia (A-O-H, n = 28), oligomenorrhea, and hirsutism, hyperandrogenemia, and polycystic ovaries (PCO-A-O-H, n = 20). A control group of age-matched adolescents (n = 30) was included., Intervention(s): Subjects underwent physical and ultrasound evaluations; fasting blood samples were taken for the measurement of endocrine and metabolic parameters., Main Outcome Measure(s): The endocrine and metabolic profiles were evaluated., Result(s): Adolescents with PCOS showed reduced insulin sensitivity and dyslipidemia. Triglycerides, and total and low-density lipoprotein cholesterol were higher in the phenotypes with hyperandrogenemia. Insulin resistance and body mass index were not significantly different between PCOS phenotypes. Triglyceride positively and high-density lipoportein cholesterol levels negatively correlated with free testosterone and free androgen index., Conclusion(s): The risk of metabolic alterations may vary in adolescent PCOS patients with different phenotypes. Hyperandrogenemia is a risk factor for dyslipidemia. This information may be of relevance in counseling adolescents with PCOS.

Objective: The prevalence of the metabolic syndrome (MBS) abnormalities in Italian adolescents with polycystic ovary syndrome (PCOS) was evaluated., Design: Retrospective chart review., Setting: University outpatient clinic., Participants: Fifty-three adolescents with PCOS., Interventions: Subjects underwent a physical evaluation. Fasting blood samples were taken for the evaluation of metabolic parameters., Main Outcome Measures: The prevalence of MBS abnormalities according to de Ferranti criteria was assessed., Results: 9.4% of adolescents with PCOS had the MBS (three abnormalities). Twelve girls (22.7%) had two abnormalities. Seventeen (32.1%) of PCOS girls have no MBS abnormalities. PCOS adolescents with the MBS were more obese, insulin resistant and they had significantly higher levels of total and free testosterone. The number of metabolic abnormalities correlated with free, total testosterone, free androgen index (FAI) and body mass index (BMI). Groups with two or three abnormalities were not differentiated by BMI, insulin, lipids, blood pressure, but they were differentiated by total and free testosterone and FAI. Adolescents with the MBS have higher total and free testosterone and FAI than girls with two MBS abnormalities., Conclusions: The MBS and its components are present in some adolescents with PCOS, placing them at increased risk for cardiovascular disease early in adulthood. Hyperandrogenemia is a risk factor for MBS independent of obesity.

Background: The introduction of transvaginal approach in ultrasound (US) has enabled the accurate evaluation of the structure of the ovary and stroma. Stroma represents an acknowledged US marker for polycystic ovary syndrome (PCOS). The proportion revealed between the stroma and the ovary surface in the median section (S/A ratio) had been indicated as a reliable marker for hyperandrogenism. In order to verify the feasibility of this determination in routine use and to confirm the efficacy of S/A ratio in predicting hyperandrogenism in PCOS, a multicentric study was performed in association with five Italian research groups., Methods: A total of 418 subjects of fertile age presenting oligomenorrhoea or secondary amenorrhoea, enlarged ovaries measuring >10 cm(3) and/or >12 follicles measuring 2-9 mm in diameter took part in the study. Clinical, US and hormonal evaluations were performed in the early follicular phase or on random days in amenorrhoeic subjects. US assessment included ovarian volume, follicle number, ovarian and stroma area in median section. The hormonal study included a baseline plasma determination of LH, FSH, estradiol (E(2)), androstenedione (A), testosterone (T), dehydroepiandrosteronesulphate, 17-hydroxy-progesterone, sex hormone-binding globulin and prolactin. Correlations and receiver operator curves were used in statistical analysis of data., Results: S/A was found to be the best significant predictor of elevated A and T levels. In order to ascertain significant cut-off values in relation to A and T levels Youden indexes were calculated and indicated 0.32 as the best cut-off for the S/A ratio., Conclusions: This work underlines the importance of stroma measure in improving US diagnosis of PCOS and suggest that this parameter may be used in routine clinical practice. In fact, multicentre study demonstrated the easy feasibility of such procedure without need of sophisticated machines or intensive training for operators.

Context: An altered lipid profile is common in polycystic ovary syndrome (PCOS) and is usually characterized by increased triglycerides and low high-density lipoprotein (HDL)-cholesterol levels. In the general population, these alterations are often associated with the increase of small low-density lipoproteins (LDLs) in the so-called "atherogenic lipoprotein phenotype" (ALP) that determines a further increase of cardiovascular risk. In this study, we evaluated the presence of ALP in the plasma of women with PCOS., Setting: Measurements and analysis of LDL size were performed at the Clinic of Endocrinology, Diabetes, and Clinical Nutrition, University Hospital, Zurich. PCOS patients were recruited at the Department of Clinical Medicine, University of Palermo, and the Department of Obstetrics and Gynecology, University of Pisa., Patients: Thirty patients with PCOS (hyperandrogenism and chronic anovulation) and 24 matched controls were studied. Anthropometric data, blood glucose, serum insulin lipid profile, and LDL size and subclasses were evaluated., Results: Compared with controls, patients with PCOS had higher plasma concentrations of insulin and triglycerides and lower HDL-cholesterol concentrations but no differences in LDL-cholesterol and total cholesterol. Patients with PCOS had smaller LDL size due to a reduction in LDL subclass I, with a concomitant increase in LDL subclasses III and IV. Fourteen PCOS patients had an increase of smaller LDL particles, and it represented the second most common lipid alteration after decrease in HDL-cholesterol. However, because in this PCOS population hypertriglyceridemia was only present in two patients, complete ALP was relatively uncommon., Conclusions: Increase of type III or type IV LDL subclasses is a common finding in PCOS and represents the second most common lipid alteration after HDL-cholesterol decrease. However, in our PCOS patients, because of relatively low triglyceride levels, complete ALP is uncommon.
