Polycystic Ovary Syndrome (PCO) is an endocrine disease that is characterized by a set of symptoms including irregular menstruation, subfertility, skin changes, hirsutism and weight gain. The pathogenesis of PCO is mostly related to increase androgens and insulin resistance. Treatment is mostly symptomatic hence metformin is being used due to its effect in decreasing gluconeogenesis and by increasing peripheral utilization of glucose, in addition to its lowering effects on androgen. Thus, Metformin role in PCO treatment ranges between managing insulin resistance, promoting ovulation and treating hirsutism to some extent. Some studies showed that Metformin is effective in lowering body weight in PCO patients, yet it is not being indicated officially for this purpose. Background: Metformin is expected to have an effect of weight reduction in PCO patients This is the scope of this research which intends to explore this action. Method: The Study design is cross sectional study using online questionnaire. Open and closed ended questions were included.  Results: Based on the results the majority shows decrease in the weight, while only one reported increase in their weight and only one had the same weight during and after treatment with metformin. Conclusions:  Metformin generally showed positive effect regarding reducing the body weight of the females diagnosed with polycystic ovarian syndrome when used alone.

Objectives. To determine the prevalence of insulin resistance (IR) and its predictors in reproductive-aged Thai women with polycystic ovary syndrome (PCOS).Methods. A cross-sectional study was conducted from May 2007 to January 2009. Participants were 250 Thai women with PCOS. Information regarding medical history and physical examination and results of 75 gram OGTT were recorded.Results. The overall prevalence of IR was 20.0%, comprising the prevalence of impaired fasting glucose, impaired glucose tolerance, and diabetic mellitus of 3.2%, 13.6%, and 5.6%, respectively. Multiple logistic regression analysis showed that the independent predictors for IR were age of ≥30 years old, waist circumference (WC) of ≥80 cm, presence of acanthosis nigricans (AN), and dyslipidemia with odds ratios (95% confidence interval) of 2.14 (1.01–4.52), 3.53 (1.28–9.75), 2.63 (1.17–5.88), and 3.07 (1.16–8.11), respectively.Conclusion. The overall prevalence of IR in reproductive-aged Thai women with PCOS is 20.0%. Age ≥30 years old, WC ≥80 cm, the presence of AN, and dyslipidemia are the significant clinical predictors.

Abstract Background: Insulin resistance (IR) is a common characteristic in women with polycystic ovary syndrome (PCOS). It has been reported that circulating Fetuin-A levels were associated with IR and type 2 diabetes mellitus (T2DM). However, in PCOS women, previous reports on changes in circulating Fetuin-A concentrations were inconsistent. Methods: A cross-sectional study was conducted, including 122 PCOS women and 85 healthy women. Circulating Fetuin-A levels were determined using an ELISA kit. Results: We found that circulating Fetuin-A concentration ranged from 196.6 to 418.2 µg/L for most normal women (95 %). Women with PCOS have higher circulating Fetuin-A levels than healthy women (437.9 ± 119.2 vs. 313.8 ± 60.4 μg/L; p <0.01). Serum Fetuin-A concentrations correlated positively with WHR, LDL-C, FIns, HOMA-IR, TEST and DHEA-S. Multivariate regression analysis showed that WHR, HOMA-IR and TEST were independent influencing factors of serum Fetuin-A. Binary logistic regression reaveled that serum Fetuin-A was associated with the .occurrence of PCOS. In addition, our ROC curve analysis found that the cutoff values for Fetuin-A to predict PCOS and IR were 366.3 and 412.6 µg/L. Conclusion: Blood Fetuin-A may be a useful biomarker for screening women with PCOS and IR.

BACKGROUND: Polycystic ovary syndrome (PCOS) is complex hormonal, metabolic and reproductive disorder and is a leading cause of female infertility. Hyperinsulinemia secondary to insulin resistance plays important role in the pathogenesis of PCOS.AIM: To assess the sensitivity of different indices of insulin resistance and their relevance in a clinical setting.MATERIAL AND METHODS: A cross-sectional study of 43 patients with PCOS and 29 noromo ovulatory women as a control group was conducted. Standard clinical, anthropometrical and hormonal testing for hyperandrogenism was conducted, as well as oral glucose tolerance test with determination of basal and stimulated glucose and insulin values.RESULTS: The dynamic I/G index showed the highest sensitivity and specificity, but the static indexes HOMA-IR and QUICKI, although based on only basal glycemic and insulinemic values, showed good sensitivity, 90.38% and 94.01% respectively. HOMA-IR showed significant positive correlation with the stimulated insulin values.CONCLUSIONS: Our results support the use of static indexes in the evaluation of insulin resistance in women with PCOS in a clinical setting, offering a simple assessment of insulin resistance in PCOS, which holds great prognostic and treatment implications.

Background: Insulin resistance (IR) occurs in 50–70% of women with polycystic ovary syndrome (PCOS) and can be applied as a prediabetic feature in PCOS. Objective: In this study, indirect methods including fasting blood sugar (FBS), fasting insulin (FI), FBS/FI ratio, and quantitative insulin sensitivity check index (QUICKI) were compared with the homeostasis model assessment of insulin resistance (HOMA-IR) as a standard technique. The association of IR to sex hormone-binding globulin (SHBG) and several hormones was also analyzed. Materials and Methods: This cross-sectional study was performed on 74 PCOS women. Sensitivity and specificity of each IR method was calculated based on HOMA-IR. Hormonal profiles of the patients were compared between the groups with defined normal and abnormal values of IR. Results: Triglyceride levels had a positive association with FBS and HOMA-IR (p = 0.002 and p = 0.01, respectively) with a negative association to QUICKI and SHBG (p = 0.02 and p = 0.02, respectively). SHBG showed a significant negative association with FBS (p = 0.001). Dehydroepiandrosterone sulfate showed a positive association with FI (p = 0.002). Seven PCOS women showed abnormal SHBG levels (< 36 nmol/L) while expressed normal values of the rest of the studied variables. FI and QUICKI had the highest sensitivity while FBS/FI and QUICKI had the highest specificity when HOMA-IR was applied as a standard test. Conclusion: SHBG and triglyceride had a significant negative and positive association with IR, respectively. HOMA-IR followed by FI and QUICKI is the most sensitive test for the detection of IR. SHBG levels can be a helpful biomarker for the diagnosis of PCOS. Key words: Polycystic ovary syndrome, Insulin resistance, Sex hormone-binding globulin.

This study was designed to differentiate the contributions of hyperandrogenism, insulin resistance (IR), and body weight to the development of endothelial dysfunction in polycystic ovary syndrome and determine the effectiveness of insulin sensitization and antiandrogenic therapy after the establishment of vascular and metabolic dysfunction using a rat model of polycystic ovary syndrome. We hypothesized that the observed endothelial dysfunction was a direct steroidal effect, as opposed to changes in insulin sensitivity or body weight. Prepubertal female rats were randomized to the implantation of a pellet containing DHT or sham procedure. In phase 1, DHT-exposed animals were randomized to pair feeding to prevent weight gain or metformin, an insulin-sensitizing agent, from 5 to 14 weeks. In phase 2, DHT-exposed animals were randomized to treatment with metformin or flutamide, a nonsteroidal androgen receptor blocker from 12 to 16 weeks. Endothelial function was assessed by the vasodilatory response of preconstricted arteries to acetylcholine. Serum steroid levels were analyzed in phase 1 animals. Fasting blood glucose and plasma insulin were analyzed and homeostasis model assessment index calculated in all animals. Our data confirm the presence of endothelial dysfunction as well as increased body weight, hypertension, hyperinsulinemia, and greater IR among DHT-treated animals. Even when normal weight was maintained through pair feeding, endothelial dysfunction, hyperinsulinemia, and IR still developed. Furthermore, despite weight gain, treatment with metformin and flutamide improved insulin sensitivity and blood pressure and restored normal endothelial function. Therefore, the observed endothelial dysfunction is most likely a direct result of hyperandrogenism-induced reductions in insulin sensitivity, as opposed to weight gain.
