Treatment And Prevention

Polycystic ovary syndrome (PCOS) is one of the most common hormonal disorders and causes of infertility in women in reproductive age. Diagnostic criteria of PCOS in adult women include: ovulation disorders, hyperandrogenism and  polycystic ovaries. According to most recommendations, 2 out of these 3 criteria are confirm the diagnosis of PCOS. In girls during puberty and in the first years after menarche, different diagnostic criteria of menstrual disorders should be taken into account (variable length of menstrual cycles, monophasic cycles) and the limited usefulness of ultrasound examination for PCOS diagnosis within 8 years after menarche. Fairly extensive differential diagnosis is also necessary, especially – exclusion of adrenal hyperandrogenism. Moreover, the diagnostic criteria of PCOS do not take into account the metabolic disorders found in most patients (obesity, insulin resistance, type 2 diabetes), which should be diagnosed as early as possible and treated appropriately. This is especially true for teenagers, in whom the unequivocal diagnosis of PCOS or its exclusion may be very difficult. Current recommendations regard hormonal contraception as the first-line therapy in PCOS, in both adult women and adolescents. Together with its beneficial effect on the reduction of hyperandrogenism and obtaining regular bleeding (which in fact are not menstruations), the unfavorable metabolic effects of hormonal contraception are emphasized, as well as the inadequacy of its use if it is expected to achieve or restore ovulation and fertility. The latest reports indicate the legitimacy of treatment aimed at correcting disorders of carbohydrate metabolism and its greater effectiveness compared to the use of oral contraceptives in both adult women and girls with PCOS. In the pharmacotherapy of insulin resistance, metformin is of fundamental importance, the use of pioglitazone, GLP-1 receptor agonists or inositols is also proposed. Adequate lifestyle and dietary modification are of major importance in the treatment and prevention of PCOS. The mechanisms of "inheritance" of PCOS and insulin resistance with the participation of epigenetic modifications are still better understood, taking into account the effects of exposure to androgen excess in utero, intrauterine growth retardation, and maternal obesity and hyperalimentation. This creates new possibilities for PCOS prophylaxis.

New Evidence

: Polycystic ovary syndrome (PCOS) is a condition that affects about 15% of women of reproductive age and is correlated with infertility, insulin resistance, and obesity. The etiology of PCOS is multifactorial and genetic, endocrine, and metabolic causes were involved. New evidence suggests a link between microorganisms residing in the digestive tracts of humans and the development of PCOS. Moreover, an imbalance in the gut microbial community could be a possible factor for the onset of insulin resistance and obesity. Hyperandrogenism, a key feature of PCOS, could also play a critical role in shaping the microbiome community. Probiotics could modify the gut microbiota and serve as a potential treatment for PCOS. Here we disclose the association between PCOS and intestinal microbiota and the possible role of probiotics as a new treatment approach.

AbstractBackgroundPolycystic ovary syndrome (PCOS) is a common, complex genetic disorder affecting up to 15% of reproductive age women worldwide, depending on the diagnostic criteria applied. These diagnostic criteria are based on expert opinion and have been the subject of considerable controversy. The phenotypic variation observed in PCOS is suggestive of an underlying genetic heterogeneity, but a recent meta-analysis of European ancestry PCOS cases found that the genetic architecture of PCOS defined by different diagnostic criteria was generally similar, suggesting that the criteria do not identify biologically distinct disease subtypes. We performed this study to test the hypothesis that there are biologically relevant subtypes of PCOS.Methods and FindingsUnsupervised hierarchical cluster analysis was performed on quantitative anthropometric, reproductive, and metabolic traits in a genotyped discovery cohort of 893 PCOS cases and an ungenotyped validation cohort of 263 PCOS cases. We identified two PCOS subtypes: a “reproductive” group (21-23%) characterized by higher luteinizing hormone (LH) and sex hormone binding globulin (SHBG) levels with relatively low body mass index (BMI) and insulin levels; and a “metabolic” group (37-39%), characterized by higher BMI, glucose, and insulin levels with lower SHBG and LH levels. We performed a GWAS on the genotyped cohort, limiting the cases to either the reproductive or metabolic subtypes. We identified alleles in four novel loci that were associated with the reproductive subtype at genome-wide significance (PRDM2/KAZN1, P=2.2×10-10; IQCA1, P=2.8×10-9; BMPR1B/UNC5C, P=9.7×10-9; CDH10, P=1.2×10-8) and one locus that was significantly associated with the metabolic subtype (KCNH7/FIGN, P=1.0×10-8). We have previously reported that rare variants in DENND1A, a gene regulating androgen biosynthesis, were associated with PCOS quantitative traits in a family-based whole genome sequencing analysis. We classified the reproductive and metabolic subtypes in this family-based PCOS cohort and found that the subtypes tended to cluster in families and that carriers of rare DENND1A variants were significantly more likely to have the reproductive subtype of PCOS. Limitations of our study were that only PCOS cases of European ancestry diagnosed by NIH criteria were included, the sample sizes for the subtype GWAS were small, and the GWAS findings were not replicated.ConclusionsIn conclusion, we have found stable reproductive and metabolic subtypes of PCOS. Further, these subtypes were associated with novel susceptibility loci. Our results suggest that these subtypes are biologically relevant since they have distinct genetic architectures. This study demonstrates how precise phenotypic delineation can be more powerful than increases in sample size for genetic association studies.

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.

Incretin Mimetics

Polycystic ovary syndrome (PCOS) is a common endocrine disorder in women of reproductive age. Metabolic sequelae associated with PCOS range from insulin resistance to type 2 diabetes mellitus (T2DM) and cardiovascular disease (CVD). Insulin resistance plays a significant role in the pathophysiology of PCOS and it is a reliable marker for cardiometabolic risk. Although insulin sensitising agents such as metformin have been traditionally used for managing metabolic aspects of PCOS, their efficacy is low in terms of weight reduction and cardiovascular risk reduction compared with newer agents such as incretin mimetics and SGLT2 inhibitors. With current pharmaceutical advances, potential therapeutic options have increased, giving patients and clinicians more choices. Incretin mimetics are a promising therapy with a unique metabolic target that could be used widely in the management of PCOS. Likewise, bariatric procedures have become less invasive and result in effective weight loss and the reversal of metabolic morbidities in some patients. Therefore, surgical treatment targeting weight loss becomes increasingly common in the management of obese women with PCOS. Newer emerging therapies, including twincretins, triple GLP-1 agonists, glucagon receptor antagonists and imeglemin, are promising therapeutic options for treating T2DM. Given the similarity of metabolic and pathological features between PCOS and T2DM and the variety of therapeutic options, there is the potential to widen our strategy for treating metabolic disorders in PCOS in parallel with current therapeutic advances. The review was conducted in line with the recommendations from the international evidence-based guideline for the assessment and management of polycystic ovary syndrome 2018.

Polycystic ovary syndrome (PCOS) is a common condition in women at reproductive age associated with reproductive and metabolic dysfunction. Proposed diagnosed criteria for PCOS include two out of three features: androgen excess, menstrual irregularity, and polycystic ovary appearance on ultrasound (PCO), after other causes of hyperandrogenism and dysovulation are excluded. Based on these diagnostic criteria, the most common phenotypes are the “classic PCOS” – hyperandrogenism and oligomenorrhea, with or without PCO; the “ovulatory phenotype” – hyperandrogenism and PCO in ovulatory women; and the “non-hyperandrogenic phenotype”, in which there is oligomenorrhea and PCO, without overt hyperandrogenism. The presence of obesity may exacerbate the metabolic and reproductive disorders associated with the syndrome. In addition, PCOS women present higher risk for type 2 diabetes and higher prevalence of cardiovascular risk factors that seems to be associated with the classic phenotype. The main interventions to minimize cardiovascular and metabolic risks in PCOS are lifestyle changes, pharmacological therapy, and bariatric surgery. Treatment with metformin has been shown to improve insulin sensitivity, lowering blood glucose and androgen levels. These effects are more potent when combined with lifestyle interventions. In conclusion, besides reproductive abnormalities, PCOS has been associated to metabolic comorbidities, most of them linked to obesity. Confounders, such as the lack of standard diagnostic criteria, heterogeneity of the clinical presentation, and presence of obesity, make management of PCOS difficult. Therefore, the approach to metabolic abnormalities should be tailored to the risks and treatment goals of each individual woman.

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.

AbstractPolycystic ovary syndrome (PCOS) is the most common hormonal disorder among reproductive-age women and is associated with a high risk for metabolic disorders. Adiposity and insulin resistance are two prevalent conditions in PCOS and the likely culprits for the heightened metabolic risk. Up to 60% of women with PCOS are considered to be overweight or obese, and even among non-obese women with PCOS there is an increased accumulation of adipose tissue in abdominal depots. Insulin resistance in PCOS is unique and independent of obesity, as even non-obese women with this condition are frequently insulin resistant. However, obesity substantially aggravates the insulin resistance and the metabolic and reproductive abnormalities in women with PCOS. Recently, it has been shown that many aspects of adipose tissue function in PCOS are abnormal, and these abnormalities likely predispose to development of insulin resistance even in the absence of obesity. This review provides an overview of these abnormalities and their impact on development of metabolic disorders. At the end, an overview of the therapeutic options for management of adiposity and its complications in PCOS are discussed.

Stress Responsivity

Polycystic ovary syndrome (PCOS) is the most common endocrinopathy affecting women of reproductive age. Although a comorbidity of PCOS is obesity, many are lean. We hypothesized that increased saturated fat consumption and obesity would exacerbate metabolic and stress indices in a rodent model of PCOS. Female rats were implanted with the nonaromatizable androgen dihydrotestosterone (DHT) or placebo pellets prior to puberty. Half of each group was maintained ad libitum on either a high-fat diet (HFD; 40% butter fat calories) or nutrient-matched low-fat diet (LFD). Irrespective of diet, DHT-treated animals gained more body weight, had irregular cycles, and were glucose intolerant compared with controls on both diets. HFD/DHT animals had the highest levels of fat mass and insulin resistance. DHT animals demonstrated increased anxiety-related behavior in the elevated plus maze by decreased distance traveled and time in the open arms. HFD consumption increased immobility during the forced-swim test. DHT treatment suppressed diurnal corticosterone measurements in both diet groups. In parallel, DHT treatment significantly dampened stress responsivity to a mild stressor. Brains of DHT animals showed attenuated c-Fos activation in the ventromedial hypothalamus and arcuate nucleus; irrespective of DHT-treatment, however, all HFD animals had elevated hypothalamic paraventricular nucleus c-Fos activation. Whereas hyperandrogenism drives overall body weight gain, glucose intolerance, anxiety behaviors, and stress responsivity, HFD consumption exacerbates the effect of androgens on adiposity, insulin resistance, and depressive behaviors.

The Impact

Background: Polycystic ovary syndrome (PCOS) is the most common endocrine abnormality among women of reproductive age. Insulin resistance is known as the hallmark of PCOS that leads to hyperinsulinemia and type 2 diabetes in PCOS patients. Objective: This study aimed to evaluate the expression pattern of IRS1 as a candidate gene in insulin resistance development in the PCOS Rat models. Methods: In this study, estradiol valerate was used for PCOS induction. Then, all of the rats were divided into five experimental groups and treated with Astragalus hamosus extract. Ethanol was used for extraction by Soxhlet, and extracts were analyzed by GC-MS. Ovarian morphology was analyzed using histological experiments. Finally, the expression of IRS1 and hormonal titration of testosterone and insulin were evaluated using qRT-PCR and ELISA assays, respectively. Results: Induction of PCOS led to an increase in body weight, which decreased after treatment with the extract. Histological assessment declared an increased number of corpus luteums in treated groups and reduced cystic follicles compared with the PCOS group. Astragalus hamosus extract-treated groups exhibited decreased levels of insulin and testosterone compared to the PCOS group. qRT-PCR results showed an increase in the expression levels of IRS1 in the treated groups compared to the PCOS group. Conclusions: This study indicated the impact of Astragalus hamosus extract on PCOS by clarifying the increased levels of IRS1 expression in the treated groups compared to the PCOS group.
