Background. Since insulin resistance and compensatory hyperinsulinemia are the major causes of the metabolic syndrome (MS) and are also the main pathophysiology of polycystic ovary syndrome (PCOS), PCOS women are at risk of MS. The aim of the present cross-sectional study was to determine the prevalence of MS in Asian women with PCOS using the International Diabetes Federation (IDF) criteria and to define the risk factors.Methods. One hundred and seventy women with PCOS were enrolled in the study from September 3, 2002 to June 14, 2005. A 75-g oral glucose tolerance test with plasma glucose and serum insulin levels was performed. Also, blood samples were examined for fasting triglycerides, high-density lipoprotein cholesterol and adiponectin levels.Results. The mean (±standard deviation) age, body mass index (BMI) and waist-to-hip ratio were 28.8±5.9 years, 27.1 ± 7.0 kg/m2 and 0.85±0.06, respectively. The prevalence of MS was 35.3%. Age, BMI, waist circumference and all metabolic parameters were higher in PCOS women with MS than in those without MS. MS prevalence increased with age, BMI and insulin resistance as determined by homeostasis model assessment (HOMA-IR), but not with adiponectin after BMI adjustment.Conclusions. According to the IDF criteria, one-third of the PCOS women had MS. This study also showed that age, BMI and HOMA-IR are important risk factors for MS. 相似文献

Objective. To compare the effect of the aromatase inhibitor letrozole and clomiphene citrate (CC) on superovulation in women with normal ovulation.Methods. A cross-over randomized study of 22 women with normal ovulation, divided randomly into two equal cohorts, was carried out. Each group of 11 women was randomly allocated to take letrozole or CC for one cycle. After washing out for one cycle, the alternative drug was administered in the subsequent cycle. The number and size of mature follicles, endometrial thickness, and estradiol and progesterone levels were monitored.Results. The number of mature follicles and estradiol levels on ovulation day were significantly lower in the letrozole group than the CC group (p < 0.05 for both). However, no differences between the two groups in endometrial thickness and pattern were observed. Progesterone levels showed ovulation in all cycles.Conclusions. The administration of 50 mg CC on days 3–5 was superior to 2.5 mg letrozole for superovulation induction in women with normal ovulation. 相似文献

Objective.?To determine serum visfatin levels in Asian polycystic ovary syndrome (PCOS) women and its correlations with various parameters.Study design.?Case–control study.Setting.?University hospital.Subjects.?Eighty women were enrolled in this study. Of these, 40 women were PCOS and 40 age-matched subjects with regular menstrual cycles were controls.Intervention.?Seventy-five gram oral glucose tolerance tests were performed in all women. Fasting venous blood samples for serum visfatin, insulin and androgen levels were obtained both from the PCOS and the control women.Main outcome measures.?Serum concentrations of visfatin, fasting insulin (FI), fasting glucose, 2-h post-load glucose (2hPG), homeostasis model assessment insulin resistance, homeostasis model assessment beta cell function, total testosterone, free testosterone, androstenedione and dehydroepiandrosterone sulfate were measured in both groups.Results.?Women with PCOS had significantly higher serum visfatin levels than the healthy controls [100.39 ± 41.90 vs. 45.09 ± 28.24 mg/ml, p < 0.01]. PCOS women also had significantly higher concentrations of all androgens (p < 0.01). Insulin resistance seemed to be greater in the PCOS than the control groups, but did not reach a statistically significant level. In the PCOS group, serum visfatin levels were positively correlated with 2hPG, and systolic blood pressure and diastolic blood pressure. Serum visfatin levels were negatively associated with FI (r = ?0.80, p = 0.03) and positively associated with systolic and diastolic blood pressure (r = 0.77, p = 0.04, r = 0.79, p = 0.03, respectively) in the sub-group of PCOS women with abnormal glucose tolerance (AGT).Conclusions.?Asian PCOS women had significantly higher serum visfatin levels than age-matched healthy controls. Their levels were significantly correlated with 2hPG and blood pressure in PCOS women, and with FI and blood pressure in PCOS women with AGT. 相似文献

Objective. To evaluate ovarian reserve assessed by hormones and sonography in women with polycystic ovary syndrome (PCOS) undergoing laparoscopic ovarian drilling (LOD).Methods. This was a cross-sectional study. Twenty-one PCOS women undergoing LOD were enrolled in the study (the LOD group). Their day-3 anti-Müllerian hormone (AMH), inhibin B, follicle-stimulating hormone (FSH) levels, antral follicles count (AFC) and summed ovarian volume representing ovarian reserve were compared with those of PCOS women who did not undergo LOD (the PCOS group) and those of normal ovulatory women (the control group).Results. There were no differences in age and body mass index between groups. AMH levels seemed to be lower in the LOD (4.60 ± 3.16 ng/ml) than in the PCOS (5.99 ± 3.36 ng/ml) groups, but did not reach statistical significance. Day-3 FSH levels were significantly higher and AFC was significantly lower in the LOD than in the PCOS group. AMH levels, AFC and summed ovarian volume were significantly greater, but FSH was significantly lower, in the PCOS group compared with the control group. There were no differences in inhibin B levels between groups.Conclusion. This study showed that ovarian reserve assessed by hormonal levels and sonography seems to be lower in the LOD than in the PCOS group. The PCOS women both with and without LOD had significantly greater ovarian reserve than the age-matched controls having normal ovulatory menstruation. 相似文献
