Polycystic ovary syndrome (PCOS) is the most common endocrinopathy in women of reproductive age. It is characterized by hyperandrogenism, polycystic ovaries, and chronic anovulation along with insulin resistance, hyperinsulinemia, abdominal obesity, hypertension, and dyslipidemia as frequent metabolic traits (metabolic syndrome) that culminate in serious long-term consequences such as type 2 diabetes mellitus, endometrial hyperplasia, and coronary artery disease. It is one of the most common causes of anovulatory infertility. A complete understanding of the underlying Pathophysiology of PCOS is still lacking. Because of the heterogeneity of this disorder, there are most likely multiple underlying pathophysiologic mechanisms. Pathogenesis of PCOS is explaining as alteration in gonadotropin-releasing hormone secretion results in increased luteinizing hormone (LH) secretion. An alteration in insulin secretion and insulin action results in hyperinsulinemia and insulin resistance. A defect in androgen synthesis that results in increased ovarian androgen production.Treatment of PCOS include maintaining a normal endometrium, antagonizing the actions of androgens on target tissues, reducing insulin resistance (when present), and correcting anovulation. Women with polycystic ovary syndrome (PCOS) are at higher risk for several other health conditions as Insulin Resistance, Metabolic Syndrome, Type 2 Diabetes, Obesity, Heart Disease and High Blood Pressure (Cardiovascular Disease)

Introduction. Polycystic ovary syndrome (PCOS) has a prevalence of 5—8% in women of reproductive age. Women with PCOS have an increased risk of metabolic syndrome and associated comorbidities. Adiponectin is a circulating protein produced by adipocytes. Circulating levels of adiponectin are inversely related to adipocyte mass. Low levels occur with insulin resistance, type 2 diabetes, metabolic syndrome, and obesity-related cardiovascular disease. This article reviews the literature on the link between adiponectin and PCOS and the potential use of adiponectin as a biomarker for PCOS. Method. Data-based studies on adiponectin and PCOS and adiponectin measurement were identified through the Medline (1950—2009) and ISI Web of Knowledge (1973—2009) databases. Results. Fifteen studies related to adiponectin and PCOS met inclusion criteria and were included in this review. These studies present evidence that adiponectin is linked to insulin resistance, insulin sensitivity, body mass index (BMI), and adiposity. In women with PCOS, lower levels, as opposed to higher levels, of adiponectin occur in the absence of adiposity. Conclusion. The relationships between adiponectin and insulin resistance and sensitivity, metabolic syndrome, and BMI in women with PCOS suggest that adiponectin potentially could serve as a marker for disease risk and provide opportunity for earlier intervention if knowledge is successfully translated from laboratory to clinical practice. However, further study of the relationship between adiponectin and PCOS is required before there can be direct application to clinical practice.

Ovary Syndrome

Polycystic ovary syndrome is the most common endocrine disorder in women of reproductive age. It affects 6% to 7% of the population and is characterized by hyperandrogenism and ovarian dysfunction. Women with the disorder often present with insulin resistance and obesity, making it importance for health care providers to monitor closely for signs and symptoms of metabolic syndrome and type 2 diabetes. Treatments are targeted toward improving insulin tolerance, reducing signs and symptoms of hyperandrogenism (hirsutism, anovulation, etc), restoring normal menstrual cycle function, and restoring fertility. Major treatment should include weight management through diet and exercise, regardless of body mass index and might include concurrent drug therapy. It is important that pharmacists understand the underlying pathophysiology of the disease and the available treatments, in addition to the importance of reducing risk of metabolic syndrome/type 2 diabetes, and cardiovascular disease in these patients.

The Metabolic Syndrome

The polycystic ovary syndrome (PCOS) is the most common cause of anovulation and hyperandrogenism in women, affecting between 5 and 10% of women of reproductive age worldwide (1). Although this difficult topic in endocrine gynaecology is under extensive research, controversies still remain about the pathophysiology, diagnosis, and therapy of PCOS. The PCOS phenotype can be structured in three components: manifestations of anovulation, hyperandrogenism, and the metabolic syndrome (of which hyperinsulinaemia secondary to insulin resistance is the central abnormality). The latter two are addressed in other chapters. Our knowledge about the mechanism of disturbed folliculogenesis in PCOS that is responsible for its reproductive aspects has much increased these last years, thus opening new avenues for the diagnostic and therapeutic approaches.

Background: Polycystic ovary syndrome is a common endocrinopathy in women of reproductive age with prevalence of 6-10% which is characterized by hyper androgenic features and chronic oligo – anovulation and polycystic ovary morphology. Most women with polycystic ovary syndrome are also characterized by metabolic abnormalities like insulin resistance, hyperinsulinemia, dyslipidemia and abdominal obesity, these forming risk factors for metabolic syndrome. The objective of the study was to compare the clinical, biochemical and hormonal profile of polycystic ovary syndrome patients with and without metabolic syndrome.Methods: A comparative cross- sectional study was undertaken on 79 PCOS women diagnosed with PCOS according to Rotterdam criteria, in which the clinical data and hormonal profile of two groups of polycystic ovary syndrome women with and without metabolic syndrome was compared.Results: The mean age of 79 patients in this study group with and without metabolic syndrome was 26.17±3.18 and 25.57±3.41 years respectively. There were more patients from urban areas as compared to rural areas and maximum patients. Significantly higher number of PCOS women with metabolic syndrome had hirsutism and acanthosis nigricans than those without metabolic syndrome. Mean value of Waist circumference, systolic BP pressure, diastolic BP, S. Triglyceride and fasting glucose were higher and HDL levels were lower in women with metabolic syndrome than those without metabolic syndrome. Fasting insulin and HOMA-IR values were significantly higher in PCOS women with metabolic syndrome in comparison to those without metabolic syndrome.Conclusion: PCOS is not only is the most frequent cause of anovulation, but it is also associated with characteristic metabolic disturbances that may have important implications for the long term health. Metabolic syndrome is a cluster of endocrine disturbances, including insulin resistance, dyslipidemia, obesity, and hypertension. It is associated with a two-fold increased risk of cardiovascular disease and a five-fold increased risk of type 2 diabetes. This illustrates the importance of early detection of insulin resistance and metabolic syndrome with subsequent application of preventive measures in women with polycystic ovary syndrome.

The Mean

Background There is an assumption that the mean and biological variation of insulin resistance (IR) is less in polycystic ovary syndrome (PCOS), and intuitively higher in type 2 diabetes (T2DM). To test this hypothesis we compared the mean and biological variation in IR in PCOS to that of T2DM and to age- and weight-matched controls. Methods Twelve PCOS, 11 matched healthy women; 12 postmenopausal diet-controlled T2DM and 11 matched healthy postmenopausal women were recruited. Blood samples were collected at 4-d intervals on 10 consecutive occasions. The biological variability of IR was derived on duplicate samples. Results Mean and biological variability of HOMA-IR for PCOS did not differ from T2DM. Both measures were higher than the matched controls. There was no difference in insulin or IR measures between the body mass index matched pre- and postmenopausal women. Percentage β cell function were 208.8%, 62.3%, 106.5% and 111.9%, respectively, in PCOS, postmenopausal women with T2DM, healthy premenopausal and healthy postmenopausal women. Conclusions The progression from PCOS to the development of T2DM is unlikely to be due to a further increase in IR (or variability), but rather the progressive failure of pancreatic beta cells with a decrease in insulin production. The clinical trial registration number for this study is ISRCTN65353256.

Insulin resistance is a key component in the pathogenesis of polycystic ovary syndrome (PCOS) and type 2 diabetes. Polymorphisms in the genes encoding the insulin receptor substrate (IRS) proteins, IRS-1 (Gly972Arg) and IRS-2 (Gly1057Asp), influence susceptibility to type 2 diabetes. This study was undertaken to assess the influence of these polymorphisms on insulin resistance, glucose tolerance, and androgen levels in nondiabetic PCOS women. We studied 227 PCOS subjects including 126 and 48 nondiabetic white and African-American subjects, respectively. The IRS-1 Gly972Arg allele frequencies were identical in whites and African-Americans [0.95 (Gly) and 0.05 (Arg)]. The IRS-2 Gly1057Asp allele frequencies were 0.85 (Gly) and 0.15 (Asp) in African-Americans and 0.59 (Gly) and 0.41 (Asp) in whites. There was no association of IRS-1 genotype with any clinical or hormonal measure in nondiabetic white or African-American PCOS subjects. However, nondiabetic subjects with the IRS-2 Gly/Gly genotype had significantly higher 2-h oral glucose tolerance test glucose levels compared with those with Gly/Asp and Asp/Asp genotypes in whites or Gly/Asp genotype in African-Americans (there were no Asp/Asp subjects in our modest size African-American sample). These results suggest that the IRS-2 Gly1057Asp polymorphism influences blood glucose levels in nondiabetic white and African-American women with PCOS. Thus, individuals with the common IRS-2 Gly/Gly genotype may be at increased risk of developing type 2 diabetes.
