The diagnosis of polycystic ovary syndrome in adolescents

Gut Microbiota and Polycystic Ovary Syndrome (PCOS): Understanding the Pathogenesis and the Role of Probiotics as a Therapeutic Strategy

Polycystic ovary syndrome (PCOS) is one of the most common disorders among women in modern societies. A variety of factors can contribute to the development of PCOS. These women often exhibit high insulin resistance (IR), hyperandrogenism, irregular periods, and infertility. Dysbiosis of the gut microbiota (GMB) in women with PCOS has attracted the attention of many researchers. Porphyromonas spp., B. coprophilus, and F. prausnitzii are found in higher numbers in the gut of women with PCOS. Short-chain fatty acids (SCFAs), produced by the intestinal microbiota through fermentation, play an essential role in regulating metabolic activities and are helpful in reducing insulin resistance and improving PCOS symptoms. According to studies, the bacteria producing SCFAs in the gut of these women are less abundant than in healthy women. The effectiveness of using probiotic supplements has been proven to improve the condition of women with PCOS. Daily consumption of probiotics improves dysbiosis of the intestinal microbiome and increases the production of SCFAs.

A systematic review on effect of sodium-glucose cotransporter-2 inhibitors on the metabolic and endocrinological profile of patients with polycystic ovarian syndrome

BACKGROUND

Polycystic ovarian syndrome (PCOS) has been a common metabolic and endocrinal disorder, prevalent amongst women belonging to the reproductive age group. The aim of this systematic review was to assess the safety and efficacy profile of sodium-glucose cotransporter 2 (SGLT2) inhibitors (Canagliflozin, Dapagliflozin, Empagliflozin, and Licogliflozin) for the treatment of women suffering from PCOS.

METHODS

A literature search in PubMed, Science Direct, Cochrane Central Register of Controlled Trials, and ClinicalTrials.gov was conducted for randomized clinical trials of SGLT-2 inhibitors in PCOS patients by applying predetermined inclusion and exclusion criteria. The articles in English language were included.

RESULTS

Four randomized controlled trials including 146 subjects were included in the review. The clinical studies indicated a significant decrease in the levels of total testosterone, free androgen index, total body fat, homeostasis model assessment-estimated insulin resistance (HOMA-IR), body mass index (BMI), dehydroepiandrosterone sulfate (DHEAS) and fasting plasma glucose (FPG). However, no significant difference was reported in levels of sex hormone-binding globulin (SHBG). Overall, there was improvement in metabolic and endocrine profiles, suggesting a potentially beneficial impact of SGLT2 inhibitors in the management of PCOS.

CONCLUSION

There is a requirement for large extensive clinical trials to demonstrate the efficacy of SGLT-2 inhibitors in PCOS patients.

The effect of coenzyme Q10 intake on metabolic profiles in women candidates for in-vitro fertilization: a randomised trial

Objective

Infertility and the pathogenesis of polycystic ovarian syndrome (PCOS) are both influenced by insulin resistance and dyslipidemia. Presumably, adding coenzyme Q10 (CoQ10) to these patients' diets will be beneficial. Therefore, this study aimed to examine the effects of CoQ10 supplementation on metabolic profiles in women candidates for in-vitro fertilization (IVF).

Trial design and methods

For this randomized, double-blinded, parallel, placebo-controlled clinical experiment, 40 PCOS-positive infertile women who were IVF candidates were included. They ranged in age from 18 to 40. The 20 participants in the two intervention groups received either CoQ10 or a placebo for 8 weeks. The expression of glucose transporter 1 (GLUT-1), peroxisome proliferator-activated receptor gamma (PPAR-γ), low-density lipoprotein receptor (LDLR), as well as metabolic profiles such as insulin metabolism and lipid profiles were evaluated. Quantitative RT-PCR determined the expression of GLUT-1, PPAR-γ, and LDLR on peripheral blood mononuclear cells. Lipid profiles and fasting glucose were assessed using enzymatic kits, and insulin was determined using Elisa kit.

Results

In comparison to the placebo, CoQ10 supplementation significantly reduced blood insulin levels (-0.3±1.0 vs. 0.5±0.7, P=0.01) and insulin resistance (-0.1±0.2 vs. 0.1±0.2, P=0.01), and increased PPAR-γ expression (P=0.01). In infertile PCOS patients' candidates for IVF, CoQ10 supplementation showed no appreciable impact on other metabolic profiles. Also, CoQ10 supplementation revealed no significant impact on GLUT-1 (P=0.30), or LDLR (P=0.27) expression. Within-group changes in insulin levels (P=0.01) and insulin resistance (P=0.01) showed a significant elevation in the placebo group. When we adjusted the analysis for baseline BMI, baseline values of variables, and age, our findings were not affected.

Conclusions

Eight weeks of CoQ10 supplementation demonstrated positive benefits on PPAR-γ expression, insulin resistance, and serum insulin in infertile PCOS women candidates for IVF.

Clinical management of androgen excess and defect in women

INTRODUCTION

Hyperandrogenism and hypoandrogenism are complex disorders involving multiple-organ systems. While androgen excess is a well-characterized condition, androgen deficiency still needs diagnostic criteria, as there are no specific cutoffs.

AREAS COVERED

We highlight the most recent findings on the role of androgens in female pathophysiology, investigating clinically relevant conditions of androgen insufficiency or excess throughout a woman's life, and their possible therapeutic management.

EXPERT OPINION

Combined oral contraceptives (COCs) should be considered as first-line therapy for the management of menstrual irregularity and/or clinical hyperandrogenism in adolescents with a clear diagnosis of polycystic ovary syndrome (PCOS). There are limited evidence-based data regarding specific types or doses of COCs for management of PCOS in women; however, the lowest effective estrogen dose should be considered for treatment. Despite evidence regarding safety, efficacy, and clinical use, testosterone therapy has not been approved for women by most regulatory agencies for treatment of hypoactive sexual desire disorder (HSDD). The long-term safety for treatments with testosterone is still to be evaluated, and this review highlights the need for more research in this area.

The Association of Polycystic Ovarian Syndrome Among Reproductive-Aged Women With Consumption of Junk Food in Jeddah, Saudi Arabia

OBJECTIVE

Polycystic ovarian syndrome (PCOS) is a common reproductive and endocrinological disorder that affects a significant percentage of women worldwide. Despite its high prevalence, the possible environmental factors that influence the development of PCOS, especially dietary habits, are still unclear. The aim of this study is to investigate the association between PCOS and junk food consumption among women of childbearing age in Jeddah, Saudi Arabia.

METHODS

A cross-sectional study was conducted from February 2023 to April 2023 in 155 women diagnosed with PCOS according to the Rotterdam criteria. Participants aged 18-47 years and living in Jeddah, Saudi Arabia completed a validated 30-item electronic questionnaire that included sociodemographic information, medical history, PCOS symptoms, and fast food consumption patterns.

RESULTS

The study revealed a high prevalence of obesity and overweight among PCOS patients, which was significantly associated with their diets high in carbohydrates, fats, and refined sugars. In addition, weight loss was difficult for these patients, which could be influenced by hormonal imbalances and dietary factors. In particular, fast food consumption showed a significant association with facial acne in PCOS patients, while some participants also experienced excessive hair growth on the face, abdomen, and back, which may be related to excessive fat intake.

CONCLUSION

This study provides evidence to support an association between junk food consumption and the prevalence of PCOS among women of reproductive age in Jeddah, Saudi Arabia. The findings suggest that dietary patterns may influence the development and treatment of PCOS, highlighting the need for lifestyle interventions as part of treatment strategies. Further studies with larger and more diverse populations, as well as longitudinal studies, are warranted to clarify causal relationships and gain a comprehensive understanding of the impact of dietary factors on the development and progression of PCOS. Identifying the potential effects of diet on PCOS can lead to more effective treatments and improve the overall health and well-being of those affected.

Antioxidant Defense Expressed as Glutathione Status and Keap1-Nrf2 System Action in Relation to Anthropometric Parameters and Body Composition in Young Women with Polycystic Ovary Syndrome

Metabolic disorders present in women with polycystic ovary syndrome (PCOS) and the associated risk of obesity may result in increased oxidative stress and reproductive failure. Therefore, we evaluated the concentrations of reduced glutathione (GSH), oxidized glutathione (GSSG), glutathione peroxidase (GPx), and reductase (GR), as well as nuclear factor erythroid 2-related factor 2 (Nrf2) and Kelch-like ECH-associating protein1 (Keap1) in the serum of 56 women with PCOS divided according to the visceral to subcutaneous fat surface ratio (VAT/SAT) and waist-to-hip ratio (WHR) values. Antioxidant parameter levels were measured by competitive inhibition enzyme immunoassay technique. As the VAT/SAT ratio and WHR increased, we observed significantly higher concentrations of GSSG and Keap1 protein and a lower value of the GSSG/GSH ratio (R-index), which is considered an index of cellular redox (p < 0.05). Negative correlations were found between the R-index and body weight, BMI, WHR, subcutaneous and visceral fat surface and the VAT/SAT ratio, and total body fat; positive links were found with fat free mass and total body water. Opposite associations were noted between GSSG level and the aforementioned body composition parameters. Oxidative stress characterized by a depleted reduced-to-oxidized glutathione index is associated with anthropometric and body composition parameters in women with PCOS. In particular, abdominal obesity expressed by the VAT/SAT ratio and/or WHR seems to have a negative impact on glutathione status, which may lead to a disruption of many biological cell processes. The observed negative association of Keap1 with R-index suggests that the elevated oxidative changes dependent on the VAT/SAT ratio may lead to Nrf2 activation to promote antioxidant enzyme expression. Although the GSH/GSSG index as well as the VAT/SAT ratio appear to be good indicators of oxidative status, studies on a larger group of patients should continue to confirm these links among women with PCOS.

The Role of Serum Anti-Mullerian Hormone Measurement in the Diagnosis of Polycystic Ovary Syndrome

Polycystic ovary syndrome (PCOS) is a common endocrinological disorder in women with significant reproductive, metabolic, and psychological health implications. The lack of a specific diagnostic test poses challenges in making the diagnosis of PCOS, resulting in underdiagnosis and undertreatment. Anti-Mullerian hormone (AMH) synthesized by the pre-antral and small antral ovarian follicles appears to play an important role in the pathophysiology of PCOS, and serum AMH levels are often elevated in women with PCOS. The aim of this review is to inform the possibility of utilizing anti-Mullerian hormone either as a diagnostic test for PCOS or as an alternative diagnostic criterion in place of polycystic ovarian morphology, hyperandrogenism, and oligo-anovulation. Increased levels of serum AMH correlate highly with PCOS, polycystic ovarian morphology, hyperandrogenism, and oligo/amenorrhea. Additionally, serum AMH has high diagnostic accuracy as an isolated marker for PCOS or as a replacement for polycystic ovarian morphology.

Prevalence of polycystic ovary syndrome under NIH criteria among the tenth-grade Chinese schoolgirls in Guangzhou area: a cross-sectional epidemiological survey

BACKGROUND

Polycystic ovary syndrome (PCOS) is currently considered to have a peri-adolescence onset and continuously influence the reproductive and metabolic health of the patients, while the diagnostic criteria among adolescent population haven't been universally unified till now. This survey seeks to preliminarily evaluate the prevalence of PCOS in the tenth grade schoolgirls in Guangzhou area under NIH criteria and analyze the clinical features of adolescents with PCOS.

METHODS

The cross-sectional epidemiological survey was carried out among the tenth grade schoolgirls in Guangzhou area by the method of cluster sampling. The contents of this survey included the questionnaire, physical exams and serum measurements. Until now, totally 1294 girls underwent this survey and 1095 serum samples were restored. 235 non-hirsute (mFG < 6), postmenarcheally 2-year girls were randomly selected as the control group, among which the cut-off value of biochemical hyperandrogenemia was set accordingly. The prevalence of PCOS among this population was preliminarily evaluated according to the NIH criteria.

RESULTS

Along with the increase of gynecological age, the menstruations of girls was becoming more regular and the incidence of oligomenorrhea or amenorrhea was declining. Even among those who were less than 2 years after menarche, those whose menstrual cycle were longer than 90 days accounted for lower than 5%. The 95th percentile of mFG score was 6 among the girls who were < 2 years after menarche, and 5 among the girls who were > 2 years after menarche. Among the 235 healthy girls, the 95th percentile values of Testosterone (T), Free androgen index (FAI) and Androstenedione (A2) were 2.28 nmol/mL, 4.37, and 5.20 nmol/mL respectively. Based on the NIH criteria, the prevalence of PCOS in this survey was 3.86%. The prevalence of adolescent PCOS tend to slightly increase with age and gynecological age, but the difference was not statistically significant. The prevalence of PCOS among obese girls was markedly higher than that in lean girls.

CONCLUSION

Based on the NIH criteria, the prevalence of PCOS among the tenth grade schoolgirls in Guangzhou area was 3.86%. The diagnosis of hyperandrogenism among adolescents should also be based on both clinical and biochemical parameters.

The Effect of Exercise on Inflammatory Markers in PCOS Women: A Systematic Review and Meta-Analysis of Randomized Trials

BACKGROUND

Polycystic ovary syndrome (PCOS) is a typical female disorder that influences different aspects of women's health. There is a direct association between inflammation and PCOS status. Some evidence supports the beneficial effects of exercise on inflammation status in PCOS women, while others cannot find a significant association. This study aimed to clarify the effect of exercise on inflammatory markers in women with PCOS.

METHOD

Electronic searches in international databases were performed to identify eligible publications up to August 2021, which compared the effects of exercise on inflammatory markers in the intervention group compared to the control group in PCOS women. A weighted mean difference (WMD) using a random-effect model was applied for reporting results.

RESULTS

A total of 2525 records were found via database searching, of which 10 were eligible to be included in the analysis. The results of the meta-analysis revealed that exercise could significantly lower the serum level of CRP (WMD: -0.43 mg/L; 95% CI: -0.66 to -0.21; P ≤ 0.01; I ²: 84.9%; P < ≤0.01), while it was not considerable for adiponectin (WMD: -0.33 μg/mL; 95% CI: -0.97 to 0.31; P=0.30; I ²: 0%; P=0.97). In addition, subgroup analyses indicated a significant effect of exercise on CRP in individuals ≥30 years, sample size ≥15 individuals, and aerobic training.

CONCLUSION

Exercise training can reduce CRP levels in women with CRP, particularly in women older than 30 years of age, and in studies with more than 15 participants. The effect of exercise on adiponectin was not noticeable.

Comparison of Clinical, Biochemical, and Sonological Parameters in Adolescents with and without Polycystic Ovarian Syndrome

Objectives The Pediatric Endocrine Society consensus criteria was developed in 2015 to diagnose adolescent PCOS. There are no Indian studies that use these criteria for diagnosis and then compare the clinical characteristics with those of normal controls. The objective of this study was to compare the clinical and biochemical profile in adolescents with and without PCOS and to study the ovarian morphology in adolescents with and without PCOS.

Materials and Methods We conducted a prospective case–control study on 60 adolescents who attended the outpatient department/adolescent immunization clinic. Group A included 30 adolescent girls with PCOS diagnosed as per the consensus criteria and Group B included 30 adolescents without PCOS. All participants were clinically evaluated and called empty stomach in the follicular phase for metabolic (Serum TSH, prolactin, FSH, LH, and testosterone) and endocrinal workup (2-hour OGTT, lipid profile) followed by ultrasonic examination.

Results In group A, 40% were overweight and 36.7% were obese and in group B, 20% were overweight and 20% were obese. There were no significant differences noted in gonadotropin levels in two groups. Mean testosterone levels were higher in PCO adolescents. The mean ovarian volume and ovarian follicle number were significantly higher in adolescents with PCOS. We found that if ultrasound criteria were added to the diagnosis, there would be about 7% lesser PCOS diagnosis.

Conclusion PCOS alters the fat distribution and lipid distribution in the body. These are features that lead to long-term metabolic alterations and life-threatening diseases. All PCOS adolescents thus be screened for these abnormalities and advised lifestyle modifications to keep these parameters under control.

Investigating the active components of Huatan Tongjing Decoction for the treatment of polycystic ovary syndrome via network pharmacology

BACKGROUND

Polycystic ovary syndrome (PCOS) is a common endocrine disease in women, potentially causing ovarian infertility for women at gestational age. Huatan Tongjing Decoction is commonly used to treat PCOS, however the involved molecular mechanism has not been fully understood.

METHODS

In this study, the active components of Huatan Tongjing Decoction and potentially targeted proteins were downloaded from the Traditional Chinese Medicine Systems Pharmacology (TCMSP) database. PCOS-related genes were accessed from Malacards database. STRING database was utilized to construct a protein-protein interaction (PPI) network based on the PCOS-related genes and the predicted targets. Subsequently, the PPI network was subjected to Random walk with restart (RWR). Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) enrichment analyses were performed on top 50 genes with the high affinity scores to the drug targets. Subsequently, based on the predicted drug components and targets, a component-gene interaction network was constructed. Finally, the most central drug targets were selected, and the corresponding compounds were subjected to molecular docking and dynamic simulations to examine their bindings.

RESULTS

The 122 main active components and 246 potential targets of Huatan Tongjing Decoction were obtained from TCMSP, and a total of 259 nodes and 1,919 interactions were acquired from the PPI network. The top 50 genes were mainly enriched in response to peptide hormone function and PI3K-Akt signaling pathway in RWR analysis. Molecular docking and dynamic simulations predicted that MMP-quercetin interaction played an important role in the treatment of PCOS using Huatan Tongjing Decoction.

CONCLUSIONS

Luteolin and quercetin in Huatan Tongjing Decoction potentially bound MMP9 and served as active compornants. This study preliminarily suggested the efficacy of Huatan Tongjing Decoction against PCOS in molecular degreee.

Is anti-Mullerian hormone a useful biomarker in the diagnosis of polycystic ovary syndrome in Chinese adolescents?

OBJECTIVE

(1) To investigate anti-Mullerian-hormone (AMH) in adolescents with polycystic ovary syndrome (PCOS) compared to age-matched girls without PCOS; (2) to determine whether AMH is a valuable marker for diagnosing PCOS and to explore the best cutoff value in adolescents; (3) using a multivariate predictive model for the diagnosis of PCOS.

METHODS

Ninety girls (aged 10-20 years) recruited during two years for the PCOS-group (n = 45) or control-group (n = 45). PCOS diagnostic criteria according guidelines of the Endocrinology Expert Group, Obstetrics/Gynecology Branch of the Chinese Medical Association. Serum AMH and other sex hormones were measured. Logistic regression analysis to estimate the odds ratio of AMH and other variables for the diagnosis of PCOS. Receiver operator characteristics (ROC) curve analysis was performed to reveal the diagnostic potential.

RESULTS

(A) AMH was significantly higher in PCOS patients than in controls (10.21 ± 5.85 ng/ml vs. 4.31 ± 2.84 ng/ml, p < .001). In PCOS-group, total testosterone (TT), free testosterone (FT) and biologically active testosterone (BioT) were significantly higher than in controls (p < .001). (B) Logistic regression suggests that AMH and TT are correlated with the diagnosis of PCOS (p < .05). (C) ROC curve analyses demonstrated that the optimal value of AMH for predicting PCOS was 6.32 ng/mL, with 69.8% sensitivity and 80.5% specificity. Furthermore, AMH combined with TT can provide 83.7% sensitivity and 80.5% specificity for diagnosing PCOS in adolescents.

CONCLUSIONS

AMH may be a useful biomarker for the diagnosis of PCOS in Chinese adolescent girls. A cutoff value of 6.32 ng/mL best discriminated between PCOS patients and controls. Besides AMH a multivariate predictive model should include TT.

A Review on the Mechanism and Application of Keishibukuryogan

The concept of "blood stasis" - called yū xiě in Chinese, Oketsu in Japanese - is one of the unique pathophysiology of traditional medicine that originated in China and inherited in Korea and Japan. This concept is related to the multiple aspects of hemodynamic disorders brought on by quantitative and qualitative changes. It theorizes that the quantitative changes of "blood stasis" are related to peripheral circulatory insufficiency. When chronic qualitative changes of "blood stasis" produce stagnant blood that turns into a pathological product, it could cause inflammation and lead to organic changes. Trauma induced hematomas, that are considered to be a quantitative change of blood, are also a form of blood stasis. The basic medicine research on Keishibukuryogan (KBG)-a Japanese name in Traditional Japanese Medicine (Kampo) for one of the most common anti- "blood stasis" prescriptions, also known as gui-zhi-fu-ling-wan (GFW) in Chinese in Traditional Chinese Medicine (TCM)-indicated that the initiation of quantitative changes was closely related to loss of redox balances on endothelial function induced by oxidative stress. The following qualitative changes were related to coagulopathy, hyper viscosity; anti-platelet aggregation, lipid metabolism; a regulation of systemic leptin level and/or lipid metabolism, inflammatory factor; cyclooxygenase-1,2 (COX-1, 2), interleukin-6, 8 tumor necrosis factor-α, macrophage infiltration, hyperplasia, tissue fibrosis and sclerosis caused by transforming growth factor-β1 and fibronectin, the dysfunction of regulated cell deaths, such as, apoptosis, autophagy, ferroptosis and ovarian hormone imbalance. Clinically, KBG was often used for diseases related to Obstetrics and Gynecology, Endocrine Metabolism, Rheumatology and Dermatology. In this review, we give an overview of the mechanism and its current clinical application of KBG through a summary of the basic and clinical research and discuss future perspective.

An update on polycystic ovary syndrome: A review of the current state of knowledge in diagnosis, genetic etiology, and emerging treatment options

Polycystic ovary syndrome is the most common endocrine disorder in women of reproductive age, which is still incurable. However, the symptoms can be successfully managed with proper medication and lifestyle interventions. Despite its prevalence, little is known about its etiology. In this review article, the up-to-date diagnostic features and parameters recommended on the grounds of evidence-based data and different guidelines are explored. The ambiguity and insufficiency of data when diagnosing adolescent women have been put under special focus. We look at some of the most recent research done to establish relationships between different gene polymorphisms with polycystic ovary syndrome in various populations along with the underestimated impact of environmental factors like endocrine-disrupting chemicals on the reproductive health of these women. Furthermore, the article concludes with existing treatments options and the scopes for advancement in the near future. Various therapies have been considered as potential treatment through multiple randomized controlled studies, and clinical trials conducted over the years are described in this article. Standard therapies ranging from metformin to newly found alternatives based on vitamin D and gut microbiota could shine some light and guidance toward a permanent cure for this female reproductive health issue in the future.

Gonadotropin releasing hormone analogue treatment of central precocious puberty is not associated with altered prevalence of polycystic ovary syndrome: a single center cohort study

Background

There is conflicting evidence regarding an association between gonadotropin releasing hormone analogue (GnRHa) therapy and polycystic ovary syndrome (PCOS). This study aimed to compare the prevalence of endocrine disorders, primarily PCOS, between women who had been treated with GnRHa for central precocious puberty (CPP) and those who were not treated.

Methods

This was a retrospective cohort study, including women diagnosed with central precocious puberty between 1989 and 2011 in a university affiliated tertiary medical center. Data collected included demographic data, medical background, clinical presentation at diagnosis and duration of treatment (zero for non-treated). Gynecologic and endocrine long-term outcomes were compared by treatment group.

Results

Fifty-one women were included in the study, 27/51 had been treated with gonadotropin releasing hormone analogue (GnRHa). Overall prevalence of PCOS was 19.6%. No statistically significant difference in prevalence of PCOS was demonstrated between the treated and non-treated groups. Similarly, overall prevalence of either clinical or laboratory hyper-androgenism, was 29.4% and 33.3%, for the treatment and non-treatment groups respectively (p = non-significant).

Conclusions

GnRHa treatment for precocious puberty is not associated with increased risk of polycystic ovary syndrome.

Urinary Metabolites Reveal Hyperinsulinemia and Insulin Resistance in Polycystic Ovarian Syndrome (PCOS)

The identification of insulin resistance and hyperinsulinemia in polycystic ovary syndrome (PCOS) is not a minor issue. The homeostasis model assessment of insulin resistance index (HOMA) is the most used index of IR (Insulin Resistance), validated in overweight and obese patients but not in normal-weight PCOS subjects, who can still present with increased insulin secretion by an oral glucose tolerance test (OGTT). The evaluation of insulin secretion and resistance represents a still unresolved problem. The aim of this study is to identify a possible yet noninvasive method to properly evaluate the insulin metabolism in young non-diabetic subjects. Girls aged 14–22 years, afferent to the center of Gynecological Diseases in Childhood and Adolescence of Cagliari (Italy), were screened for PCOS. A total of 42 subjects comprised the study group. Hormonal assays, OGTT, transabdominal (TA) or transvaginal (TV) US, and urine collection for ¹H-NMR analysis were assayed in the early follicular phase. A ¹H-NMR coupled multivariate statistical analysis was performed. The OPLS model indicated that the NMR profile of urine had a good fit and prediction ability for the AUC OGTT with R² = 0.813. Metabolomics can be a promising tool to the potential identification of biomarkers of an exaggerated insulin response to OGTT and can encourage substantial progress for a more accurate and early diagnosis in PCOS.

Association of Prx4, Total Oxidant Status, and Inflammatory Factors with Insulin Resistance in Polycystic Ovary Syndrome

INTRODUCTION

Chronic inflammation and oxidative stress conditions have been reported in women with polycystic ovary syndrome (PCOS). Peroxiredoxin 4 (Prx4) is a related antioxidant in insulin synthesis. We hypothesized that insulin resistance in these women is associated with total oxidant status (TOS) and inflammatory factors.

MATERIALS AND METHODS

Two hundred three people including 104 PCOS patients and 99 healthy women, who were matched for age and body mass index (BMI), entered the study. Waist circumference of the participants was measured; serum glucose, lipid profile, insulin, Prx4, TOS, hs-CRP, and TNF-α were also evaluated.

RESULTS

The Prx4 level was significantly lower in PCOS than in the control group. In addition, marked increase was observed in the concentration of TOS, hs-CRP, and TNF-α in PCOS, compared to the healthy women. There was a positive correlation of TOS with hs-CRP, TNF-α, and HOMA-IR. The risk of PCOS for subjects with high hs-CRP was 60 times greater than those who had low serum hs-CRP concentration; after performing multiple logistic regression analyses with the backward method, TNF-α was considered as an effective biomarker to predict PCOS β = 49.087 (all p < 0.05).

CONCLUSION

This study identified increased oxidative stress and inflammation in PCOS; this may be due to decrease in the antioxidants, such as Prx4.

Attainment and maintenance of pubertal cyclicity may predict reproductive longevity in beef heifers†

We hypothesized the manner that heifers achieve puberty may indicate their future reproductive longevity. Heifers with discontinued or delayed cyclicity during puberty attainment may have irregular reproductive cycles, anovulation, and infertility in their first breeding season contributing to a shorter reproductive lifespan. Therefore, plasma progesterone (P4) was measured from weaning to breeding on 611 heifers born 2012-2017 and four pubertal classifications were identified: (1) Early; P4 ≥ 1 ng/ml < March 12 with continued cyclicity, (2) Typical; P4 ≥ 1 ng/ml ≥ March 12 with continued cyclicity, (3) Start-Stop; P4 ≥ 1 ng/ml but discontinued cyclicity, and (4) Non-Cycling; no P4 ≥ 1 ng/ml. Historical herd records indicated that 25% of heifers achieved puberty prior to March 12th in the 10 years prior to the study. Start-Stop and Non-Cycling yearling heifers were lighter indicating reduced growth and reproductive maturity traits compared with Early/Typical heifers. In addition, Non-Cycling/Start-Stop heifers were less responsive to prostaglandin F2 alpha (PGF2α) to initiate estrous behavior and ovulation to be artificially inseminated. Non-Cycling heifers had fewer reproductive tract score-5 and reduced numbers of calves born in the first 21-days-of-calving during their first breeding season. Within the Start-Stop classification, 50% of heifers reinitiated cyclicity with growth traits and reproductive parameters that were similar to heifers in the Early/Typical classification while those that remained non-cyclic were more similar to heifers in the Non-Cycling group. Thus, heifers with discontinued cyclicity or no cyclicity during puberty attainment had delayed reproductive maturity resulting in subfertility and potentially a shorter reproductive lifespan.

Comparison of PCOS phenotypes in adolescent and young adult Mediterranean women with possible PCOS

PURPOSE

During adolescence, PCOS features are supposed to be in evolution. Because of this, the diagnosis of PCOS in adolescence is often unclear and few studies have compared adolescent and adult PCOS phenotype distribution and features. The aim is to compare phenotypes in adolescents and young adults with PCOS.

METHODS

109 girls aged from 13 to 19 years were retrospectively studied. All patients had a gynecological age > 2 years. 63 patients were adolescents (3-5 years beyond menarche) while 46 patients were young adults (6-9 years beyond menarche). Diagnosis of different PCOS phenotypes (A, B, C, D) was made according to the Rotterdam criteria. Clinical data (menstrual cycles, BMI, presence of hirsutism), androgen circulating levels (total testosterone, androstenedione, dehydroepiandrosterone sulphate) and ovarian morphology by ultrasound were assessed.

RESULTS

109 patients presented PCOS according to the Rotterdam criteria. Phenotype A was by far the most common phenotype (73.4%) followed by phenotype B (21.1%). Only few patients had phenotype C (4.6%) or phenotype D (0.9%). When patients were divided in two groups (adolescent and young adult patients), no significant difference in prevalence and features of the different phenotypes was observed.

CONCLUSION

In this cohort of adolescent and young adult women with PCOS, the progression of age does not change the prevalence and the features of main PCOS phenotypes. It suggests that the Rotterdam criteria might be used also in adolescents, at least in those with 2 or more years of gynecological age, for the diagnosis of PCOS.

Polycystic ovary syndrome: Pathways and mechanisms for possible increased susceptibility to COVID-19

In 75% of women with polycystic ovary syndrome (PCOS), insulin action is impaired. In obesity, visceral adipose tissue becomes dysfunctional: Chronic inflammation is favored over storage, contributing to the development of metabolic complications. PCOS, metabolic syndrome (MetSy) and non-alcoholic fatty liver disease (NAFLD) apparently share common pathogenic factors; these include abdominal adiposity, excess body weight and insulin resistance. Alterations in the gut microbiome have been noted in women with PCOS compared to controls; these may lead to deterioration of the intestinal barrier, increased gut mucosal permeability and immune system activation, hyperinsulinemia and glucose intolerance, which hamper normal ovarian function and follicular development (all being hallmarks of PCOS). It has been proposed that PCOS may entail higher susceptibility to coronavirus disease 2019 (COVID-19) via its associated comorbidities (NAFLD, obesity, MetSy and alterations in the gut microbiome). Studies have found an association between acute respiratory distress syndrome (seen in severe cases of COVID-19) and the intestinal microbiome. Furthermore, apparently, severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) can gain entry to the gastrointestinal tract via locally-expressed angiotensin converting enzyme type 2 receptors. Excess body weight is associated with more severe COVID-19 and increased mortality. Although robust links between SARS-CoV-2 infection and PCOS/NAFLD/gut microbiome/metabolic consequences are yet to be confirmed, it seems that strategies for adapting the intestinal microbiome could help reduce the severity of COVID-19 in women with PCOS with or without NAFLD, MetSy or obesity.

The effect of lutein and Urtica dioica extract on in vitro production of embryo and oxidative status in polycystic ovary syndrome in a model of mice

BACKGROUND

Polycystic ovary syndrome (PCOS) is one of the most prevalent endocrinopathies in women during the reproductive age. Herbal medicines are used increasingly alone or in supplement with chemical medicines for the treatment of different diseases and dysfunctions. This study was aimed to evaluate the effects of lutein and nettle (Urtica dioica) extract on the biochemical parameters and the reproductive function in the PCOS model of mice.

METHODS

Following the induction of PCOS by dehydroepiandrosterone (DHEA), the mice (n = 98) were randomly assigned into seven groups, each consisting of fourteen mice; the groups were included control group (received solvent), PCOS group (received 6 mg/100 g B.W/day IP, DHEA for 21 days), PCOS+ Nettle extract (200 and 400 mg/kg), PCOS+ Lutein (125 and 250 mg/kg), and PCOS+ NL (200 mg/kg nettle extract and 125 mg/kg lutein). The nettle extract and lutein were administrated using gavage for 30 consecutive days after PCOS induction. Malondialdehyde (MDA), total antioxidant capacity (TAC), and estrogen were measured in serum, ovary, and uterus samples by the ELISA method. The total number of oocytes, oocyte quality, fertilization rate, 2-cell blastocyst, and arrested embryos (type I, type II, and type III) were also investigated.

RESULTS

A combination treatment of the nettle and lutein produced the lowest concentration of MDA in comparison to other groups which affected by the PCOS. The lowest level of TAC was observed in the PCOS group without treatment. The number of oocytes, oocyte quality, fertilization rate, and 2-cell blastocyst were significantly higher in the control group, but the lowest values were observed in the PCOS group without any treatment.

CONCLUSIONS

The most favorable findings include improving antioxidant capacity, oocyte and embryo quality were observed in the PCOS+ 125 L group.

Polycystic ovary syndrome in adolescents: Q-TOF LC/MS analysis of human plasma metabolome

Polycystic ovary syndrome (PCOS) is a hormonal disorder common among women of reproductive age. Women with PCOS may have infrequent or prolonged menstrual periods or excess male hormone levels. Metabolomics provide information on early biochemical changes in patients. Our aim was to find potential biomarkers on metabolome level to notice PCOS in adolescents and propose treatment opportunities based on our findings on metabolome level. In this study, Q-TOF LC/MS based analysis of the plasma samples of 15 healthy adolescents as control group (Group C) were compared with the plasma samples of 15 adolescents having PCOS (Group T). Raw chromatograms were processed on XCMS using Isotopologue Parameter Optimization (IPO) to optimize XCMS parameters. Finally, 2288 peaks were found but 84 of them had fold changes >1.5 based on normalized peak areas and they were statistically different (p < 0.05) between the groups. These peaks were subjected to MetaboAnalyst 4.0 - MS Peaks to Pathways utility for putative identification. The final list based on putative identification were evaluated through a clinical perspective and the statistically proved variation on the metabolite profiles of Group T and Group C presented that PCOS directly affected the lipid metabolism in the body or occurred as a result of a deformation in the lipid metabolism. Lower amount of Gamma-Tocopherol and higher amount of Coenzyme Q9, which is a product of incomplete Coenzyme Q10 biosynthesis, in the plasma samples of adolescent PCOS patients encouraged us to suggest larger randomized placebo controlled studies for Gamma-Tocopherol and Coenzyme Q10 supplements on the disease situation since our findings on metabolome level were in an accordance with the previous clinical findings.

Comparison of metabolic and obesity biomarkers between adolescent and adult women with polycystic ovary syndrome

PURPOSE

Knowledge of adolescent and adult phenotypes of women with polycystic ovary syndrome (PCOS) might drive opportune management. The aim of this study was to compare metabolic and obesity biomarkers between adolescent and adult women with PCOS.

METHODS

This observational study compared biomarkers of obesity and metabolism derangements between adolescent (n = 62) and adult (n = 248) women with PCOS. Predictors of metabolic syndrome (MS) were investigated using univariate and multivariate binary logistic regression analysis.

RESULTS

The postmenarcheal age of adolescents was 4.9 ± 0.03 years. Systolic blood pressure was lower in adolescents than in adults (112.3 mmHg vs 117.0 mmHg, p = 0.001) Diastolic blood pressure was also lower in adolescents (70.7 mmHg vs 75.8 mmHg, p < 0.001). Glucose intolerance (12.0% vs 19.3%) and insulin resistance (18.2% vs 17.7%) were similar in both groups (p > 0.05, for comparisons). Impaired fasting glucose was lower in adolescents (1.8% vs 11.6%, p = 0.015). Total cholesterol and low-density lipoprotein cholesterol were lower in adolescents (p < 0.001). MS in adolescents and adults were found in 10.3% and 27.8%, respectively (p = 0.005). Visceral adiposity index (VAI) was a good predictor of MS in both adolescents (OR = 12.2), and adults (OR = 9.7).

CONCLUSIONS

Most biomarkers of glucose metabolism abnormalities were similar in adolescents and adults with PCOS. The prevalence of MS was lower in adolescents. VAI was a strong predictor of metabolic syndrome, both in adolescent and adult women with PCOS.

Liraglutide mends cognitive impairment by averting Notch signaling pathway overexpression in a rat model of polycystic ovary syndrome

AIMS

Polycystic ovary syndrome (PCOS), the rifest endocrine disorder in women, is involved in disrupting many metabolic processes. However, the impact of PCOS on cognitive deficits is still uncertain. Recently, Notch signaling pathway was identified as a key modifier in regulating the pathological process in the ovary and various neurodegenerative disorders. Liraglutide has favourable neuroprotective effects that may protect against the possible cognitive dysfunction in PCOS.

MAIN METHODS

PCOS was induced in rats by administrating Letrozole orally for 21 successive days. Then, Liraglutide (LIR) was administered intraperitoneally for 30 days. Memory was examined using Y-maze, novel object recognition (NOR), and Morris water maze (MWM) tests. Western blotting, enzyme immunoassay, and quantitative real-time PCR were used to examine Notch signaling downstream targets, as well as assessing the expression of the components of various pathways cross talked with Notch signaling in memory impairment. Furthermore, histopathological examination was performed to examine neuronal changes.

KEY FINDINGS

Notch signaling was overexpressed in PCOS rats, which increased Aβ aggregation, apoptosis, and neuroinflammation. Additionally, histopathological examination showed neuronal degeneration, which was marked by diminished acetylcholine levels in the PCOS rats' hippocampi. Finally, serum levels of insulin and testosterone were elevated while estradiol was reduced. Treatment with LIR repaired Notch signaling-attributed changes and improved the PCOS-induced memory impairment in rats.

SIGNIFICANCE

The obtained findings confirm that Notch signaling activation in the hippocampus of rats impairs cognitive functions in PCOS, which is mitigated by LIR. Therefore, LIR may offer a novel therapeutic intervention to impede PCOS-induced dementia.

Polycystic ovary Syndrome in Adolescents: Pitfalls in Diagnosis and Management

PURPOSE OF REVIEW

Polycystic ovary syndrome (PCOS) is the commonest endocrine disorder during a woman's reproductive lifespan, with well-documented diagnostic criteria and therapeutic strategies in adults; the same is not necessarily true for adolescents. The purpose of this review was to identify frequent pitfalls in PCOS diagnosis and management during adolescence.

RECENT FINDINGS

Although there is no global consensus on the definition, most experts converge to the presence of both oligo/amenorrhea and (clinical and/or biochemical) hyperandrogenism, as a prerequisite for diagnosis in adolescents. The former criterion includes: (a) consecutive menstrual intervals > 90 days even in the first year after menarche; (b) menstrual intervals persistently < 21 or > 45 days for ≥ 2 years after menarche; or (c) lack of menses by the age of 15 or 2-3 years after pubarche. However, these menstrual irregularity patterns may overlap with other common entities in adolescents, such as frequent or infrequent uterine bleeding or anovulation due to immaturity of the hypothalamic-pituitary-ovarian axis. Clinical signs of hyperandrogenism are obscure, without well-validated criteria. Finally, the criterion of polycystic morphology cannot be safely used in adolescents, mostly due to technical limitations of the transabdominal ultrasound. Except for the efficacy of lifestyle intervention in overweight and obese adolescents with PCOS, limited and low-quality data exist regarding the available medications, such as oral contraceptives, metformin, and anti-androgens. Individualized management, guided by clinical experience and research data and close monitoring appear the most effective approach in this PCOS population for optimal control of its reproductive and metabolic outcomes. Research focusing on PCOS genetic and molecular mechanisms may elucidate what diagnostic and therapeutic strategies will be most appropriate in adolescents with PCOS in the future.

The Role of Visceral Adiposity Index as Predictor of Metabolic Syndrome in Obese and Nonobese Women with Polycystic Ovary Syndrome

Background: To evaluate anthropometric-metabolic biomarkers as predictors of metabolic syndrome (MS) in women with polycystic ovary syndrome (PCOS) with and without obesity. Methods: This was an observational cross-sectional study. Patients were classified as nonobese-PCOS (body mass index, BMI <30 kg/m², n = 385), and obese-PCOS (BMI ≥30 kg/m², n = 261). The anthropometric parameters waist circumference, waist/hip ratio, lean body mass, fat body mass, visceral adiposity index (VAI), lipid accumulating product, and biomarkers of glucose and lipid metabolisms were compared between groups. Binominal logistic regression analyses were performed to identify predictors of MS. Results: Obesity was diagnosed in 40% of all PCOS women (P < 0.001). Blood pressure and anthropometric abnormalities were significantly more frequent in obese-PCOS women (P < 0.001, for all comparisons). Glucose metabolism markers were higher in obese-PCOS compared with nonobese-PCOS (P < 0.001, for all comparisons). High-density lipoprotein cholesterol was lower in obese group than in nonobese group (1.26 mM vs. 1.08 mM, P < 0.001). MS was found in 23 of 385 (6%) nonobese-PCOS and in 116 of 261 (44.4%) obese-PCOS (P < 0.001). VAI was the best predictor of MS in both nonobese-PCOS (OR = 4.1, 95% CI 1.5-11.1) and obese-PCOS (OR = 12.9, 95% CI 5.7-29.0). Conclusions: MS is more prevalent in PCOS women with obesity. VAI was the strongest predictor of MS in both obese and nonobese PCOS women, and can be applied in clinical practice for early detection of risk for MS and precocious intervention in women with PCOS, particularly in obese women.

Pathophysiological roles of chronic low-grade inflammation mediators in polycystic ovary syndrome

Polycystic ovary syndrome (PCOS) is the most common hormonal imbalance disease in reproductive-aged women. Its basic characteristics are ovulatory dysfunction and ovarian overproduction of androgens that lead to severe symptoms such as insulin resistance, hirsutism, infertility, and acne. Notwithstanding the disease burden, its underlying mechanisms remain unknown, and no causal therapeutic exists. In recent years, further studies showed that inflammation processes are involved in ovulation and play a key role in ovarian follicular dynamics. Visceral adipose tissue can cause inflammatory response and maintenance of the inflammation state in adipocytes by augmented production of inflammatory cytokines, monocyte chemoattractant proteins, and recruitment of the immune cell. Therefore, the PCOS can be related to a low-grade inflammation state and inflammatory markers. Investigating the inflammatory processes and mediators that contribute to the commencement and development of PCOS can be a critical step for better understanding the pathophysiology of the disease and its treatment through inhibition or control of related pathways. In the present review, we discuss the pathophysiological roles of chronic low-grade inflammation mediators including inflammasome-related cytokines, interleukin-1β (IL-1β), and IL-18 in PCOS development.

Awareness and opinion about polycystic ovarian syndrome (PCOS) among young women: a developing country perspective

OBJECTIVE

To explore the perception on PCOS and its prevalence among adolescent and young women.

METHODS

The study was conducted over 2 year period in a tertiary care teaching hospital from Eastern India. A pre-formed, validated questionnaire was used to record the details. Descriptive statistics was used to report the findings.

RESULTS

Of 965 young patients with mean (SD) age 20.64 (2.1) years, 27 (2.79 %) were aware of an entity called PCOS. Awareness among adolescents with PCOS was 25.9 % (7/27). All aware patients belonged to the urban sector with professionals constituting around 48%, of which 11% were students. The major source of information among aware patients was from doctors (40.7%), and friends and Internet (25.9%); rest being from books, newspapers, and teachers. Majority (70%) were aware that diet restriction and exercise were the primary modalities of treatment, whereas, only 3.7% knew about the role of contraceptive pills in PCOS.

CONCLUSIONS

Awareness regarding PCOS among the young women is very low mainly in the rural set up. Doctors and health staffs should play a major role in spreading awareness of the entity to prevent long term complications.

Current treatment for polycystic ovary syndrome: focus on adolescence

Polycystic ovary syndrome (PCOS) is the most frequent endocrine disorder in women and it is associated with an increased rate of infertility. Its etiology remains largely unknown, although both genetic and environmental factors play a role. PCOS is characterized by insulin resistance, metabolic disorders and low-grade chronic inflammation. To date, the treatment of PCOS is mainly symptomatic and aimed at reducing clinical signs of hyperandrogenism (hirsutism and acne), at improving menstrual cyclicity and at favoring ovulation. Since PCOS pathophysiology is still largely unknown, the therapeutic interventions currently in place are rarely cause-specific. In such cases, the therapy is mainly directed at improving hormonal and metabolic dysregulations typical of this condition. Diet and exercise represent the main environmental factors influencing PCOS. Thus, therapeutic lifestyle changes represent the first line of intervention, which, in combination with oral contraceptives, represent the customary treatment. Insulin resistance is becoming an increasingly studied target for therapy, most evidence stemming from the time-honored metformin use. Relatively novel strategies also include the use of thiazolidinediones and GLP1-receptor agonists. In recent years, a nutraceutical approach has been added to the therapeutic toolkit targeting insulin resistance. Indeed, emerging data support inositol and alpha-lipoic acid as alternative compounds, alone or in combination with the aforementioned strategies, with favorable effects on ovulation, insulin resistance and inflammation. Nevertheless, additional studies are required in adolescents, in order to assess the effectiveness of diet supplements in preventing negative impacts of PCOS on fertility in adult age. This review focuses on the main therapeutic options for PCOS to date.

Quality of Life and Emotional States of Depression, Anxiety and Stress in Adolescents with Polycystic Ovary Syndrome: A Cross-Sectional Study

BACKGROUND

The chronic condition of polycystic ovary syndrome (PCOS) in adolescents can affect different aspects of quality of life in them. This study aimed to determine the correlation between the quality of life with emotional states of depression, anxiety, and stress in adolescents with PCOS.

METHODS

This is a cross-sectional study conducted on 120 adolescents with PCOS in Tehran, Iran in 2019. The sociodemographic checklist, quality of life, depression, anxiety and stress (DASS) were assayed by valid and reliable questionnaires. The Pearson's correlation coefficient and linear regression were used for data analysis, which was performed by SPSS (V.22).

RESULTS

The mean (SD) age and menarche age of participants were 16.58 (1.36) and 12.52 (1.19) years, respectively. The most common clinical symptoms of adolescence were irregular menstruation (85%) and acne (61.7%). According to the result of this study, there was a significant reverse correlation between total score of SF-12 with total scores of depression, anxiety and stress (r=-0.395, p=0.001) and a significant reverse correlation was also found between each dimension of DASS scale and 12-Item Short Form Survey (SF-12) (p<0.001). Based on the linear regression model and after controlling the demographic variables, there was a linear regression relationship between total DASS score and SF-12 (Beta= -0.367, p= 0.003).

CONCLUSION

The study results reveal the role of emotional states of depression, anxiety, and stress in the quality of life of adolescents with PCOS. Based on our findings, we emphasize the interventional studies and guides for improving all dimensions of quality of life and reducing the psychological burden of PCOS in later life of adolescence.

Changes in clinical and biochemical characteristics of polycystic ovary syndrome with advancing age

OBJECTIVE

To verify whether aging can modify the clinical and biochemical characteristics of women with polycystic ovary syndrome (PCOS).

MATERIAL AND METHODS

This observational cross-sectional study was conducted at the reproductive endocrinology clinics of Julio Muller University Hospital and Tropical Institute of Reproductive Medicine in Cuiabá, MT, Brazil, between 2003 and 2017. Both, 796 PCOS and 444 non-PCOS normal cycling women underwent the same examination. PCOS was diagnosed using the Rotterdam criteria as recommended for adolescent and adult subjects. Anthropometric, metabolic, and endocrinological modifications with aging were initially examined in the two groups: control and PCOS. Further analyses were performed after a 5-year age stratification of data throughout the reproductive period. All participants signed a consent form approved by the local ethical committee.

RESULTS

Biomarkers of adiposity were more remarkable in African descendant PCOS women. Body weight, waist/hip ratio, fat mass, and BMI were higher in PCOS women and tended to increase at all 5 age-strata, between ≤19 and 35 years of age. Serum androgen levels decreased with aging, markedly in PCOS subjects (P < 0.01 for all age-strata comparisons), but remained elevated when compared with the levels found in controls. Carbohydrate markers, triglycerides, and total cholesterol tended to increase over time in PCOS (P < 0.01 for all age-strata comparisons). Total cholesterol also tended to increase with age in non-PCOS women (P = 0.041).

CONCLUSION

The present study has shown that the advancing age influences many features of PCOS women. Biochemical hyperandrogenism, the core criterion recommended in the current systems to define the syndrome, showed statistically significant tendencies to decrease with aging progression but did not normalize. The use of age-adjusted features for the diagnosis of PCOS are recommended.

Correlation Between Physiologic and Osteopathic Measures of Sympathetic Activity in Women With Polycystic Ovary Syndrome

Background

Polycystic ovary syndrome (PCOS) is a common hormone disorder that affects the reproductive, metabolic, and psychological health of reproductive-aged females, with a number of long-term health risks, including type 2 diabetes mellitus and cardiovascular sequelae. Sympathetic hyperactivity in affected persons may be involved in the pathogenesis of the disorder.

Objective

To determine whether physiologic and osteopathic measures of increased sympathetic tone correlate in a population of women with PCOS.

Methods

For this descriptive observational study, women with PCOS between the ages of 20 and 44 years were recruited. Physiologic measures of sympathetic tone (resting heart rate and blood pressure, resting heart rate variability, and postexercise heart rate recovery and blood pressure) were compared with osteopathic measures of sympathetic tone (Chapman points and viscerosomatic reflexes) for the heart, adrenal glands, and ovaries.

Results

Twenty-four women participated in the study. Overall, the participants exhibited both physiologic and osteopathic signs of increased sympathetic tone compared with reference values. In some participants, the number of osteopathic findings were greater than the number of physiologic findings of increased sympathetic tone.

Conclusions

Women with PCOS exhibit increased sympathetic tone by physiologic and osteopathic measures, indicating the utility of assessing sympathetic hyperactivity in these patients by osteopathic methods. Osteopathic structural examination is a valuable diagnostic tool that may allow detection of sympathetic hyperactivity in women with PCOS even before physiologic symptoms manifest. The osteopathic indicators of increased sympathetic tone may represent potential therapeutic targets to improve health in this population. (ClinicalTrials.gov NCT03383484).

Metabolic Syndrome in Adolescents with Polycystic Ovary Syndrome: Prevalence on the Basis of Different Diagnostic Criteria

STUDY OBJECTIVE

Existing literature on the prevalence of metabolic syndrome (MBS) in adolescents with polycystic ovary syndrome (PCOS) is inconsistent, likely because of the application of differing diagnostic criteria. The objective was to assess the prevalence of MBS in adolescents with PCOS depending on the PCOS diagnostic criteria used.

DESIGN, SETTING, AND PARTICIPANTS

A retrospective chart review of female patients (N = 37), ages 11-22 years, diagnosed with PCOS between January 2013 and December 2017. Patients were included only if they had received screening allowing comparison across all PCOS diagnostic criteria: National Institutes of Health, Rotterdam, Androgen Excess Society, Amsterdam, Endocrine Society, and the Pediatric Endocrine Society (PES). The presence of MBS was established using the International Diabetes Federation criteria. The proportion of patients having MBS was then calculated for each PCOS diagnostic criteria subgroup.

INTERVENTIONS AND MAIN OUTCOME MEASURES

For the entire study cohort, MBS was present in 17/37 patients (45.9%). The highest prevalence of MBS was among the subgroup of patients meeting the PES PCOS diagnostic criteria (13/25; 52.0%), whereas the lowest prevalence was in the subgroup meeting the Amsterdam PCOS criteria (6/15; 40.0%). Those diagnosed using the PES criteria also had the highest percentage of patients with 3 or more risk factors for MBS.

RESULTS AND CONCLUSION

The prevalence of MBS varied according to the specific PCOS diagnostic criteria and was highest when PES guidelines were used. The PES criteria are adolescent-specific and have thus refined the diagnosis of PCOS for this population. Our results highlight the importance of validated adolescent-specific PCOS diagnostic criteria.

The effects of physical exercise on cardiometabolic outcomes in women with polycystic ovary syndrome not taking the oral contraceptive pill: a systematic review and meta-analysis

Purpose

Women with polycystic ovary syndrome (PCOS) exhibit many metabolic abnormalities that are associated with an increased cardiovascular disease risk. Exercise may promote improvements in lipid profile and insulin sensitivity in women with PCOS. There is however, a knowledge gap on the optimal dose of exercise, regarding duration, intensity, type, and frequency of exercise. The aim of this systematic review and meta-analysis was to define effective types of exercise to improve cardiometabolic profile in PCOS.

Methods

We included randomised controlled trials (RCT), quasi-RCT, and controlled clinical trials focusing on reproductive-aged women diagnosed with PCOS. Eligible interventions included those with at least two weeks of supervised exercise sessions. Primary outcomes were blood lipids, blood glucose, blood pressure, measures of abdominal adiposity, and inflammation markers. Secondary outcomes were total and free testosterone, sex hormone binding globulin, and measures of insulin resistance. Nine electronic databases were searched from inception to present for English language publications. The Cochrane Risk Assessment tool was used to assess bias in the included studies. Outcomes were quantitatively synthesised and a meta- analysis was performed. Pooled effect estimates and 95% confidence intervals were presented.

Results

This systematic review identified three trials, including 231 participants with PCOS, that examined the effect of structured, supervised exercise on cardiometabolic outcomes. Analysis of pooled data indicated statistical favourable effects of exercise on total cholesterol, fasting glucose, waist circumference and waist-to-hip ratio, systolic blood pressure, C-reactive protein, total testosterone, and sex hormone binding globulin using post-intervention scores.

Conclusions

Moderate aerobic exercise interventions ≥3 months in duration, with a frequency of 3/week for at least 30-min, may have favourable effects on various cardiometabolic risk factors in women with PCOS. However, results should be interpreted with caution. Many of the outcomes were based on studies with serious methodological limitations, and only one “gold-standard” RCT was identified.

Efficacy of combination therapy of inositols, antioxidants and vitamins in obese and non-obese women with polycystic ovary syndrome: an observational study

Polycystic ovarian syndrome (PCOS) is one of the most common endocrine disorders in women of both developed and developing countries. It is associated with insulin resistance, hyperinsulinemia, hyperandrogenism, oxidative stress and various long-term complications. The present study was undertaken to evaluate the efficacy and safety of the supplementation (Trazer F Forte^TM-CORONA Remedies Pvt. Ltd.) providing combination of insulin sensitising agents (myo-inositol, D-chiro-inositol and chromium picolinate), antioxidants (N-acetylcysteine and lycopene) and vitamins (vitamin D, biotin and folic acid) in women with PCOS. After 12 weeks of supplementation, a significant improvement was observed in menstrual cyclicity, acne and hirsutism in both obese and lean PCOS patients. A significant reduction was observed in body weight and BMI of obese subjects. However, both parameters remain unchanged in lean subjects. We suggest that combination therapy of insulin sensitising agents, antioxidants and vitamins may be a fruitful approach for the management of PCOS.Impact statementWhat is already known on this subject? Monotherapy of insulin sensitising agents, antioxidants and vitamins is beneficial in the treatment of PCOS.What do the results of this study add? Combined use of insulin sensitising agents (myo-inositol, D-chiro-inositol and chromium picolinate), antioxidants (N-acetylcysteine and lycopene), and vitamins (vitamin D, biotin and folic acid) is safe and effective in obese and non-obese women with PCOS.What are the implications of these findings for clinical practice and/or further research? Since PCOS is a multifactorial and a complex endocrine disorder, combination therapy can be used for the comprehensive management of PCOS.

Polycystic Ovary Syndrome in Adolescents: Challenges in Diagnosis and Treatment

CONTEXT

Despite the importance of timely diagnosis and treatment of polycystic ovary syndrome (PCOS) among adolescent females, considering the paucity of data focusing on this group and controversies documented on its recognition and management, the purpose of this review was to summarize challenges and recommendations of diagnosis and treatment for adolescents with PCOS.

EVIDENCE ACQUISITION

This review summarizes papers documented on PCOS among adolescent females. PubMed, Scopus, Web of Science, and Google Scholar databases were searched for retrieving studies conducted on PCOS among adolescent females up to March, 2019. The final selection of papers was made based on their relevancy with the fields of diagnosis and treatment of PCOS in this age group.

RESULTS

Oligo-anovulation in adolescents, if persistent, is a matter for concern. Hirsutism and moderate to severe acne in adolescent females should be considered as clinical manifestations of hyperandrogenism (HA). Diagnosis of biochemical HA in adolescents with PCOS requires reliable tests using well-defined normal ranges. In adolescent females, an elevated androgen level (hyperandrogenemia) alone is not enough to detect HA, unless it is persistent and associated with anovulation. Metabolic disorders should not be used as diagnostic criteria of PCOS among adolescent females. Re-assessment of all adolescent females with probable PCOS, using reliable diagnostic criteria, is needed to avoid over diagnosis and unnecessary treatment in healthy normal females without HA. In adolescent females with PCOS, the main clinical problem is the control of menstrual irregularity and hirsutism; treatment approaches for these patients are primarily directed at the major clinical manifestations and complaints. Lifestyle modifications are baseline interventions, which can be added to special treatments, such as Oral Contraceptives (OCs), metformin, or antiandrogens for most adolescents with PCOS, particularly those with overweight or obesity.

CONCLUSIONS

This review emphasizes the use of standard diagnostic criteria for PCOS, developed for adolescents. Although early recognition and management of PCOS in adolescents can prevent long-term complications associated with this syndrome, clinicians should re-evaluate all such patients with features very similar to PCOS to avoid over/incorrect diagnosis using precise criteria, suggested for this age group.

PCOS diagnosis in adolescents: the timeline of a controversy in a systematic review

Study objective Polycystic ovary syndrome (PCOS) in adolescence, a disorder of exclusion, has proved to be a timeless diagnostic challenge for the clinician. Since 1990, several attempts to provide clear diagnostic criteria have been published, most of the time leading to inconsistencies. We attempted to elucidate the controversies and convergences of this subject by conducting a systematic review of the literature concerning official guidelines or proposed criteria for the diagnosis of PCOS in adolescent girls. Design Based on a term search sequence via electronic databases such as Pubmed, Cochrane, Embase, Scopus and a hands-on review of references and learned societies, all available data were classified and analyzed. Single case reports, original studies with adult population or articles with incomplete diagnostic guidelines were excluded. Results Twelve reports dated from 2006 to 2018 fulfilled the inclusion criteria. Seven of them were endorsed or published by learned societies. All suggested a stricter diagnosis than in adulthood. Polycystic ovarian morphology was used as a necessary criterion only in three guidelines, and there was a tendency for a more objective diagnosis of hyperandrogenism, defined either by clinical features or by biochemical hyperandrogenemia, although in one case both were required. Conclusion Irregular menstrual cycles, allowing for an interval of at least 2 years postmenarche, and hyperandrogenism, usually reinforced by biochemical confirmation, are the main accepted features for PCOS diagnosis in adolescence. Discrepancies among endocrine and reproductive medicine societies still remain, although recent intensified attempts at reaching a consensus should allow for more universally accepted diagnostic criteria.

Metabolic and hormonal assessment of adolescent and young adult women with prior premature adrenarche

OBJECTIVE

Follow-up studies of girls with premature adrenarche have reported the development of polycystic ovary syndrome, insulin resistance, and dyslipidemia and a propensity to cardiovascular disease. The aim of this study was to analyze the presence of these conditions in patients previously treated at the Universidade Federal do Triângulo Mineiro.

METHODS

A total of 130 medical records reported premature adrenarche. One hundred and twenty-two patients were invited to participate, of whom 54 accepted; 34 patients were selected, as they had reached their final height. Anthropometric, blood glucose, insulin, and lipid and hormonal profile (LH, FSH, estradiol, 17α-OH-progesterone, androstenedione, dehydroepiandrosterone sulfate, testosterone) data were obtained, the HOMA-IR index was calculated, and pelvic ultrasonography was performed. To characterize polycystic ovary syndrome and metabolic syndrome, the Rotterdam and International Diabetes Federation criteria, respectively, were used. Data were analyzed according to measures of dispersion, frequency and correlations of interest.

RESULTS

The age of the participants ranged from 15.2 to 28.2 years/months; 23.5% of the patients were overweight, 11.8% were obese, 29.4% had a large waist circumference, and 8.8% were hypertensive. None of the patients had altered glucose levels, and insulin levels and HOMA-IR were elevated in 29.4% and 38.2% of the participants, respectively; 14.7% of the patients exhibited acanthosis nigricans. The lipid profiles of the participants were variable, and one patient (2.9%) had metabolic syndrome. Polycystic ovary syndrome was found in 41.2% of patients.

CONCLUSION

The percentage of patients with polycystic ovary syndrome who also had overweight, obesity and insulin resistance corroborates the literature data about the need for follow-up aiming at interventions, especially for conditions associated with cardiometabolic risk.

Polycystic ovary syndrome in adolescents

Menstrual irregularity and evidence of hyperandrogenism are characteristic features of polycystic ovary syndrome (PCOS) in adolescents. Diagnosis of PCOS is challenging as clinical features cannot be differentiated from the events of normal development. The specific aetiology of PCOS is not known but it is a complex disease resulting from interplay of genetic susceptibility, intrauterine, extra-uterine and environmental factors. Obesity and insulin resistance are common associations, because of which patients are at high risk for metabolic and cardiovascular diseases. Lifestyle modifications are recommended in all patients with pharmacological agents to control features of hyperandrogenism and menstrual disturbances. This chapter discusses the pathogenesis of PCOS and diagnosis of PCOS in adolescents and the difficulties in diagnosis. In brief the associated co-morbidities and management are discussed.

Development of Ovulatory Menstrual Cycles in Adolescent Girls

Irregular menstrual cycles due to anovulation are well described in the first few years after menarche, but the normal developmental trajectory from anovulatory to mature ovulatory cycles during adolescence remains undefined. In this article we review the very limited understanding of this final stage of female reproductive axis development and discuss why additional research in this area is critical to the health of women.

Fetal programming by androgen excess in rats affects ovarian fuel sensors and steroidogenesis

Fetal programming by androgen excess is hypothesized as one of the main factors contributing to the development of polycystic ovary syndrome (PCOS). PCOS is more than a reproductive disorder, as women with PCOS also show metabolic and other endocrine alterations. Since both ovarian and reproductive functions depend on energy balance, the alterations in metabolism may be related to reproductive alterations. The present study aimed to evaluate the effect of androgen excess during prenatal life on ovarian fuel sensors and its consequences on steroidogenesis. To this end, pregnant rats were hyperandrogenized with testosterone and the following parameters were evaluated in their female offspring: follicular development, PPARG levels, adipokines (including leptin, adiponectin, and chemerin as ovarian fuel sensors), serum gonadotropins (LH and FSH), the mRNA of their ovarian receptors, and the expression of steroidogenic mediators. At 60 days of age, the prenatally hyperandrogenized (PH) female offspring displayed both an irregular ovulatory phenotype and an anovulatory phenotype with altered follicular development and the presence of cysts. Both PH groups showed altered levels of both proteins and mRNA of PPARG and a different expression pattern of the adipokines studied. Although serum gonadotropins were not impaired, there were alterations in the mRNA levels of their ovarian receptors. The steroidogenic mediators Star, Cyp11a1, Cyp17a1, and Cyp19a1 were altered differently in each of the PH groups. We concluded that androgen excess during prenatal life leads to developmental programming effects that affect ovarian fuel sensors and steroidogenesis in a phenotype-specific way.

Minimal difference in phenotype between adolescents and young adults with polycystic ovary syndrome

OBJECTIVE

To test the hypothesis that the polycystic ovary syndrome (PCOS) phenotype, or its component features, is less severe in adolescents than in young adult patients, in a referred (clinical) population.

DESIGN

Cross-sectional study.

SETTING

Tertiary-care academic medical center.

PATIENT(S)

Two hundred seventy-four adolescents and young adults aged 13.0-24.9 years with PCOS according to the National Institute of Health 1990 criteria. Patients were categorized as adolescents (AD: 13.0-18.9 years; n = 91) and young adults (YA: 19.0-24.9 years; n = 183). Adolescents were further categorized as early adolescents (Early-AD: 13.0-15.9 years; n = 31) and late adolescents (Late-AD: 16.0-18.9 years; n = 60).

INTERVENTION(S)

History, physical examination, hormonal assays with the use of standardized protocols.

MAIN OUTCOME MEASURE(S)

Unadjusted and adjusted odds ratios (ORs; adjusted for body mass index [BMI] when applicable) were calculated for biochemical hyperandrogenism (HA), hirsutism (HIR), acne, and degree of oligo/amenorrhea (OA). PCOS phenotypes were classified as HIR+HA+OA, HA+OA, and HIR+OA.

RESULT(S)

Our analysis demonstrated minimal significant difference in the prevalence of the three PCOS phenotypes, or component features, between AD and YA patients. The risks for obesity were higher for YA versus AD, and the risk of acne was lower for YA versus AD. There was no significant difference between Early-AD and Late-AD. BMI-adjusted models did not significantly modify the main findings.

CONCLUSION(S)

The present study suggests that the PCOS phenotype is established in early adolescence, remains constant into adulthood, and is not related to BMI.

The association of hs-CRP and fibrinogen with anthropometric and lipid parameters in non-obese adolescent girls with polycystic ovary syndrome

Background The aim of the study was to evaluate high-sensitivity C-reactive protein (hs-CRP) and fibrinogen in non-obese normoinsulinemic adolescent girls with polycystic ovary syndrome (PCOS) and their relationship with anthropometric and lipid parameters. Methods The study comprised a total of 26 adolescent girls newly diagnosed with PCOS and 12 healthy controls with regular ovulatory menstrual cycles. The concentration of hs-CRP, fibrinogen, anthropometric measurements, and biochemical and hormonal testing were assessed. Results PCOS adolescent girls had significantly higher levels of hs-CRP and fibrinogen compared to healthy controls. In univariate regression analysis, statistically significant associations of hs-CRP and fibrinogen levels of PCOS patients have been shown with body mass index (BMI), waist circumference (WC), hip circumference (HC) and low-density lipoprotein (LDL)/high-density lipoprotein (HDL) ratio, while hs-CRP levels were also associated with cholesterol and LDL. In the multivariate regression model, we found that hs-CRP levels were predicted by BMI (β=0.541, p<0.001) and LDL (β=0.507, p=0.014), while fibrinogen levels were predicted by BMI (β=0.449, p=0.004). Conclusions We have shown an association of proinflammatory indices hs-CRP and fibrinogen with anthropometric and lipid parameters of adolescent women with PCOS. The inflammatory markers might be useful in monitoring normal-weight adolescent women with PCOS in an effort to timely prevent unfavorable changes in body mass and lipid profile.

New Diagnostic Criteria of Polycystic Ovarian Morphology for Adolescents: Impact on Prevalence and Hormonal Profile

BACKGROUND

The ultrasonographic criteria used to identify polycystic ovarian morphology (PCOM) during adolescence have changed over time. Recently, a Worldwide Pediatric Consensus (PedC) defined PCOM using stricter criteria than the previous recommendations of the Rotterdam Consensus (RC) and Androgen Excess-Polycystic Ovarian Syndrome Society (AES/PCOS) criteria. The aim of this study was to determine the prevalence of PCOM in healthy adolescents according to the 3 reported diagnostic criteria and compare the hormonal profile in females with and without PCOM based on the PedC criteria.

METHODS

Nonobese adolescents (n = 102) with regular menstrual cycles were studied. Transabdominal ultrasound and hormonal profiles were assessed during the follicular phase. PCOM was defined on the basis of the 3 published criteria.

RESULTS

On the basis of the PedC, RC, and AES/PCOS criteria, PCOM was diagnosed in 13, 34, and 24% of adolescents, respectively. Adolescents with and without PCOM according to the PedC criteria had similar androgen levels. Serum anti-Müllerian hormone (AMH) levels were elevated in adolescents with PCOM, irrespective of the criteria used.

CONCLUSIONS

Use of the new PedC diagnostic criteria for PCOM results in a lower prevalence of this ultrasonographic pattern in adolescents, but this condition is not associated with hyperandrogenism. Elevated AMH is associated with PCOM in adolescents regardless of the criteria used to determine the ultrasonographic pattern.

An International Consortium Update: Pathophysiology, Diagnosis, and Treatment of Polycystic Ovarian Syndrome in Adolescence

This paper represents an international collaboration of paediatric endocrine and other societies (listed in the Appendix) under the International Consortium of Paediatric Endocrinology (ICPE) aiming to improve worldwide care of adolescent girls with polycystic ovary syndrome (PCOS)1. The manuscript examines pathophysiology and guidelines for the diagnosis and management of PCOS during adolescence. The complex pathophysiology of PCOS involves the interaction of genetic and epigenetic changes, primary ovarian abnormalities, neuroendocrine alterations, and endocrine and metabolic modifiers such as anti-Müllerian hormone, hyperinsulinemia, insulin resistance, adiposity, and adiponectin levels. Appropriate diagnosis of adolescent PCOS should include adequate and careful evaluation of symptoms, such as hirsutism, severe acne, and menstrual irregularities 2 years beyond menarche, and elevated androgen levels. Polycystic ovarian morphology on ultrasound without hyperandrogenism or menstrual irregularities should not be used to diagnose adolescent PCOS. Hyperinsulinemia, insulin resistance, and obesity may be present in adolescents with PCOS, but are not considered to be diagnostic criteria. Treatment of adolescent PCOS should include lifestyle intervention, local therapies, and medications. Insulin sensitizers like metformin and oral contraceptive pills provide short-term benefits on PCOS symptoms. There are limited data on anti-androgens and combined therapies showing additive/synergistic actions for adolescents. Reproductive aspects and transition should be taken into account when managing adolescents.

The Diagnostic Value of Anti-Müllerian Hormone in Early Post Menarche Adolescent Girls with Polycystic Ovarian Syndrome

STUDY OBJECTIVE

Polycystic ovarian syndrome (PCOS) is a common endocrine disorder characterized by hyperandrogenism and chronic anovulation, which affects 5%-10% of reproductive-age women. Diagnosis of adult patients with PCOS is made easily with clinical and laboratory methods and the anti-Müllerian hormone (AMH) level are accepted as a good indicator. However, there is still no complete consensus on the diagnosis of PCOS in adolescents.

DESIGN AND SETTING

Prospective cohort study, December 2013 to November 2014.

PARTICIPANTS

The study was conducted on adolescent girls with oligomenorrhea, with at least 2 years since menarche. The study group consisted of adolescent girls with complete PCOS and incomplete PCOS. A control group was formed of healthy adolescent girls. Complete PCOS was diagnosed according to the Rotterdam criteria, as the presence of all the following characteristics: oligomenorrhea, hyperandrogenism, and polycystic ovarian morphology on ultrasound image. Incomplete PCOS was accepted as "oligomenorrhea and polycystic ovarian morphology," or "oligomenorrhea and hyperandrogenism."

INTERVENTIONS AND MAIN OUTCOME MEASURES

All patients underwent a physical examination and the anthropometric assessments, insulin resistance, and acanthosis nigricans were recorded. It was also noted whether or not the patient had an acne score. The Ferriman-Gallwey score was applied to evaluate hirsutism.

RESULTS

The results of this study showed that no statistically significant difference was found between the PCOS and incomplete PCOS groups and the control group with respect to AMH levels.

CONCLUSION

The use of adult-specific diagnostic methods in adolescence might result in an incomplete diagnosis and inadequate treatment plan. Although the serum AMH level clearly facilitates the diagnosis of PCOS, the use of the AMH level in adolescence in PCOS diagnosis is still controversial and further studies are needed.

Diagnosis, treatment and prevention of pediatric obesity: consensus position statement of the Italian Society for Pediatric Endocrinology and Diabetology and the Italian Society of Pediatrics

The Italian Consensus Position Statement on Diagnosis, Treatment and Prevention of Obesity in Children and Adolescents integrates and updates the previous guidelines to deliver an evidence based approach to the disease. The following areas were reviewed: (1) obesity definition and causes of secondary obesity; (2) physical and psychosocial comorbidities; (3) treatment and care settings; (4) prevention.The main novelties deriving from the Italian experience lie in the definition, screening of the cardiometabolic and hepatic risk factors and the endorsement of a staged approach to treatment. The evidence based efficacy of behavioral intervention versus pharmacological or surgical treatments is reported. Lastly, the prevention by promoting healthful diet, physical activity, sleep pattern, and environment is strongly recommended since the intrauterine phase.

Do Different Diagnostic Criteria Impact Polycystic Ovary Syndrome Diagnosis for Adolescents?

STUDY OBJECTIVE

Although early diagnosis of polycystic ovary syndrome (PCOS) in adolescents might allow for earlier treatment and prevention of chronic disorders, incorrect or premature diagnosis carries risks of unnecessary treatment and psychological distress. There is no consensus concerning which diagnostic criteria to use for adolescents and current criteria vary. The objective of this study was to determine whether using different diagnostic criteria will affect PCOS diagnosis in adolescents.

DESIGN, SETTING, AND PARTICIPANTS

Fifty-two patients aged 13-18 years with at least 2 of the following criteria were included in the study: (1) oligomenorrhea or amenorrhea; (2) Clinical or biochemical hyperandrogenism; and (3) polycystic ovaries on ultrasonography. Patients were then categorized according to the 6 different criteria for PCOS. National Institutes of Health, Rotterdam criteria, Androgen Excess Society, Amsterdam criteria, Endocrine Society criteria, and the Pediatric Endocrine Society criteria. The characteristics of adolescents who were diagnosed with PCOS were also evaluated.

INTERVENTIONS AND MAIN OUTCOME MEASURES

Forty-one patients out of 52 (78.8%) received diagnosis with National Institutes of Health and Endocrine Society criteria, all with Rotterdam criteria, 45/52 (86.5%) with Androgen Excess Society criteria, 36/52 (69.2%) with Amsterdam criteria and 34/52 (65.4%) with the Pediatric Endocrine Society criteria.

RESULTS AND CONCLUSION

This study shows that the choice of guideline used does have a great effect on whether an adolescent received the PCOS diagnosis or not. For physicians using the broader criteria, care should be taken to ensure the patient does not receive diagnosis because of the physiological changes seen during puberty, which might mimic PCOS. For those using stricter criteria, close monitoring of patients who do not receive diagnosis is necessary to prevent chronic complications.

The effect of vitamin D supplementation on insulin resistance, visceral fat and adiponectin in vitamin D deficient women with polycystic ovary syndrome: a randomized placebo-controlled trial

INTRODUCTION

Low plasma 25-hydroxy-vitamin D (25OHD) is associated with polycystic ovary syndrome (PCOS). Vitamin D deficiency may contribute to the development of insulin resistance, visceral fat and low level of adiponectin which are common feature in PCOS women. This study aimed to evaluate the effect of vitamin D supplementation on insulin resistance, visceral fat, and adiponectin in hypovitaminosis D women with polycystic ovary syndrome.

METHODS

In this randomized, placebo-controlled clinical trial, 44 PCOS women aged 20-38 years with plasma 25OHD <20 ng/mL were randomized in the intervention or placebo groups and followed for 8 weeks. Participants received 50,000 IU of oral vitamin D3 once weekly in the intervention group or placebo. The visceral adipose tissue, Insulin resistance (HOMA-IR), HOMA-B, QUICKI, and circulating adiponectin were compared before and after the intervention within groups using paired tests and the mean changes were analyzed between two groups by independent t-test.

RESULTS

Of 44 eligible participates, 36 patients (81.8%) completed the study. After 8 week intervention, vitamin D supplementation compared to the placebo group significantly decreased fasting plasma glucose (FPG) (7.67 ± 7.66 versus 1.71 ± 7.50 mg/dL, p = .001) and significantly increased homeostasis model of assessment-estimated B cell function (HOMA-B) (129.76 ± 121.02 versus 48.32 ± 128.35, p = .014), Adiponectin (5.17 ± 8.09 versus -5.29 ± 8.64 mg/dL, p = .001), and serum vitamin D level (28.24 ± 6.47 versus 3.55 ± 4.25 ng/mL, p = .001).

CONCLUSION

Vitamin D supplementation in vitamin D deficient women with PCOS, improved the FPG, HOMA-B, Adiponectin, and serum vitamin D level.

Very low dose of flutamide in the treatment of hyperandrogenism

Hyperandrogenism is a condition affecting 5-10% of adolescents. The aim of this study was to evaluate the efficacy of very low dose of flutamide in the treatment of hyperandrogenism in adolescence. One hundred and fifty-eight patients, presenting severe acne and/or hirsutism, received 62.5 mg/day of flutamide + ethinylestradiol + gestodene for 18 months. The patients were subjected to assessments of hepatic enzymes levels. Thirty subjects treated with drospirenone + ethinylestradiol represented the control group. After 18 months of treatment, it was obtained a decrease of hirsutism (-39.9%), an almost recovery of acne (98% of patients) with better results of those obtained in control group. Only one case of light hypertransaminasemia was recorded, regressed spontaneously. Very low dose of flutamide was successful and safe and in the treatment of hyperandrogenism in adolescence.
