The Diagnosis of Polycystic Ovary Syndrome in Adolescents

Menstrual pattern in polycystic ovary syndrome and hypothalamic-pituitary-ovarian axis immaturity in adolescents: a systematic review and meta-analysis

OBJECTIVE

To analyze differences in the menstrual pattern, age at menarche, and body mass index (BMI) in adolescents with Hypothalamic-Pituitary-Ovarian (HPO) axis immaturity and Polycystic Ovary Syndrome (PCOS) through a systematic review and meta-analysis.

METHODS

The PubMed, EMBASE, Web of Science, Virtual Health Library, Scopus databases were searched using combinations of descriptors. Study quality was assessed using the Newcastle-Ottawa Scale. For data analysis, the results were grouped into PCOS group and NPCOS group (HPO axis immaturity). We performed a meta-analysis of raw data and the inverse variance method, employing the standardized mean difference, of the age at menarche and BMI of adolescents.

RESULTS

Participants totaled 1,718 from nine selected studies. The meta-analysis showed that the PCOS group had a higher BMI than the NPCOS group (SMD 0.334; CI95% 0.073 - 0.595; p = .012). The degree of heterogeneity of the studies was approximately 40%. No significant difference in age at menarche (SMD - 0.027; CI95% -0.227 - 0.172; p = 0.790) and menstrual patterns was found, but amenorrhea was described only in adolescents with PCOS.

CONCLUSIONS

The main characteristic in menstrual pattern that differentiated PCOS patients from girls with HPO axis immaturity was amenorrhea. Also, the BMI of PCOS patients was nearly one third higher than that of adolescents with HPO axis immaturity.

Time to cycle regularity and health risks

PURPOSE OF REVIEW

Adolescents often have irregular menstrual cycles after menarche until the reproductive axis fully matures. This review explores how menstrual regularity is established and the health risks associated with prolonged time to cycle regularity in adolescents.

RECENT FINDINGS

Cross-sectional studies show an association between prolonged time to cycle regularity in adolescents and increased risks for ongoing menstrual dysfunction, cardiometabolic disorders, cancers, and overall mortality. Importantly, some of these cardiometabolic associations are independent of PCOS status.

SUMMARY

The menstrual cycle can be used as a vital sign for assessing overall health. While further longitudinal studies are needed to establish causal relationships, these findings highlight a crucial window for early intervention in adolescents with prolonged time to cycle regularity to mitigate future risks.

The Search for the Causes of Common Hyperandrogenism, 1965 to Circa 2015

From 1965 to 2015, immense strides were made into understanding the mechanisms underlying the common androgen excess disorders, premature adrenarche and polycystic ovary syndrome (PCOS). The author reviews the critical discoveries of this era from his perspective investigating these disorders, commencing with his early discoveries of the unique pattern of plasma androgens in premature adrenarche and the elevation of an index of the plasma free testosterone concentration in most hirsute women. The molecular genetic basis, though not the developmental biologic basis, for adrenarche is now known and 11-oxytestosterones shown to be major bioactive adrenal androgens. The evolution of the lines of research into the pathogenesis of PCOS is historically traced: research milestones are cited in the areas of neuroendocrinology, insulin resistance, hyperinsulinism, type 2 diabetes mellitus, folliculogenesis, androgen secretion, obesity, phenotyping, prenatal androgenization, epigenetics, and complex genetics. Large-scale genome-wide association studies led to the 2014 discovery of an unsuspected steroidogenic regulator DENND1A (differentially expressed in normal and neoplastic development). The splice variant DENND1A.V2 is constitutively overexpressed in PCOS theca cells in long-term culture and accounts for their PCOS-like phenotype. The genetics are complex, however: DENND1A intronic variant copy number is related to phenotype severity, and recent data indicate that rare variants in a DENND1A regulatory network and other genes are related to PCOS. Obesity exacerbates PCOS manifestations via insulin resistance and proinflammatory cytokine excess; excess adipose tissue also forms testosterone. Polycystic ovaries in 40 percent of apparently normal women lie on the PCOS functional spectrum. Much remains to be learned.

Puberty classifications in beef heifers are moderately to highly heritable and associated with candidate genes related to cyclicity and timing of puberty

Introduction: Pubertal attainment is critical to reproductive longevity in heifers. Previously, four heifer pubertal classifications were identified according to attainment of blood plasma progesterone concentrations > 1 ng/ml: 1) Early; 2) Typical; 3) Start-Stop; and 4) Non-Cycling. Early and Typical heifers initiated and maintained cyclicity, Start-Stop started and then stopped cyclicity and Non-Cycling never initiated cyclicity. Start-Stop heifers segregated into Start-Stop-Discontinuous (SSD) or Start-Stop-Start (SSS), with SSD having similar phenotypes to Non-Cycling and SSS to Typical heifers. We hypothesized that these pubertal classifications are heritable, and loci associated with pubertal classifications could be identified by genome wide association studies (GWAS). Methods: Heifers (n = 532; 2017 - 2022) genotyped on the Illumina Bovine SNP50 v2 or GGP Bovine 100K SNP panels were used for variant component estimation and GWAS. Heritability was estimated using a univariate Bayesian animal model. Results: When considering pubertal classifications: Early, Typical, SSS, SSD, and Non-Cycling, pubertal class was moderately heritable (0.38 ± 0.08). However, when heifers who initiated and maintained cyclicity were compared to those that did not cycle (Early+Typical vs. SSD+Non-Cycling) heritability was greater (0.59 ± 0.19). A GWAS did not identify single nucleotide polymorphisms (SNPs) significantly associated with pubertal classifications, indicating puberty is a polygenic trait. A candidate gene approach was used, which fitted SNPs within or nearby a set of 71 candidate genes previously associated with puberty, PCOS, cyclicity, regulation of hormone secretion, signal transduction, and methylation. Eight genes/regions were associated with pubertal classifications, and twenty-two genes/regions were associated with whether puberty was attained during the trial. Additionally, whole genome sequencing (WGS) data on 33 heifers were aligned to the reference genome (ARS-UCD1.2) to identify variants in FSHR, a gene critical to pubertal attainment. Fisher's exact test determined if FSHR SNPs segregated by pubertal classification. Two FSHR SNPs that were not on the bovine SNP panel were selected for additional genotyping and analysis, and one was associated with pubertal classifications and whether they cycled during the trial. Discussion: In summary, these pubertal classifications are moderately to highly heritable and polygenic. Consequently, genomic tools to inform selection/management of replacement heifers would be useful if informed by SNPs associated with cyclicity and early pubertal attainment.

Increased oxidative stress is associated with hyperandrogenemia in polycystic ovary syndrome evidenced by oxidized lipoproteins stimulating rat ovarian androgen synthesis in vitro

PURPOSE

To determine the relationship between serum total testosterone (TT) levels and oxidative stress indices in patients with polycystic ovary syndrome (PCOS), and to investigate the effect of oxidative stress on androgen synthesis and its mechanism in rat ovarian theca-interstitial (T-I) cells.

METHODS

Clinical, hormonal, metabolic, and oxidative stress parameters were analyzed in a cross-sectional case-control study including 626 patients with PCOS and 296 controls. The effects of oxidized low-density lipoprotein (ox-LDL) and oxidized high-density lipoprotein (ox-HDL) on cell proliferation, TT secretion, and expression of key enzymes involved in testosterone synthesis were evaluated in T-I cells.

RESULTS

Serum TT levels were elevated with an increase in ox-LDL levels, whereas glutathione concentrations were lower in the high-TT subgroup than in the low-TT subgroup. The average ovarian volume and ox-LDL and malondialdehyde levels were significant predictors of TT levels in the multivariate regression models. In a rat ovarian T-I cell model, lipoprotein and oxidized lipoprotein treatments stimulated proliferation and promoted testosterone secretion. The mRNA and protein levels of 17α-hydroxylase were significantly higher in oxidized lipoprotein-treated cells than those in lipoprotein-treated cells. The mRNA levels of cholesterol side chain cleavage enzyme and steroidogenic acute regulatory protein were also significantly higher in ox-HDL-treated cells than in HDL-treated cells.

CONCLUSIONS

Oxidative stress can promote androgen production by up-regulating the expression of testosterone synthesis-related enzymes in vitro and may be an essential factor in elevating serum TT levels in patients with PCOS.

A preliminary report comparing the effect of Asafoetida with oral contraceptive on polycystic ovarian syndrome in a double-blind randomized trial

Objective

Polycystic ovarian syndrome (PCOS) is the most common cause of infertility and endocrine disorders in women of childbearing age. In Persian medicine, Ferula assafoetida L. (Asafoetida) was recommended for treating PCOS. The present study was conducted to compare the effect of Asafoetida with oral contraceptive tablets on PCOS patients.

Materials and Methods

Patients with PCOS (n=30) were enrolled in a double-blind randomized clinical trial. On Day 5 of the menstrual cycle, patients received two periods of 21-day treatment, with 7 days rest between the two treatments. On a daily basis, half of the patients (n=15) received Asafoetida (1 g), and the rest received low dose oral contraceptive (LD; one tablet). Menstrual status, anthropometric characteristics, hematology and biochemistry parameters, ovarian ultrasound examination and hirsutism were evaluated prior to the initiation of the experiment and 14 days after the end of treatment. The occurrence of menstrual cycles and pregnancy was assessed eight months after the end of treatment.

Results

The incidence of pregnancy was greater in patients who received Asafoetida compared to those who received LD (p=0.019). The time intervals between menstrual cycles became shorter in both groups (p<0.05). The occurrence of regular menstrual cycles remained longer in the Asafoetida compared to the LD group (p=0.001). Concentrations of triglycerides, cholesterol, HDL and LDL were significantly increased after treating with LD (p<0.05).

Conclusion

In PCOS patients, the occurrence of regular menstrual cycles and the incidence of pregnancy were improved following treatment with Asafoetida. This medicament could be considered a safe treatment for patients with PCOS.

Practise Updates: Diagnosis and Management of Idiopathic Hirsutism

Idiopathic hirsutism (IH) is a common clinical condition with multiple diagnostic and therapeutic uncertainties. There are no clear recommendations for the diagnosis and management of the condition. This practice update was developed to guide the primary care physicians and the specialists in better and more systematic management of IH particularly in the Indian context. Twelve experienced members consisting of eminent endocrinologists, physicians, a dermatologist, a gynaecologist and a psychiatrist were invited by the Integrated Diabetes and Endocrine Academy (IDEA). A literature search was performed using online databases from PubMed, Cochrane Library and Google Scholar. Published articles from peer-reviewed indexed journals, with a preference for meta-analyses and randomized controlled trials, were selected. A meeting took place with all the 12 members individually giving their opinions on predetermined questions of interest. After the initial meeting during IDEACON 2023, two more meetings were held and the practice update was formulated after voting. Practice updates were made on important areas such as the cut-off for modified Ferriman-Gallwey Score for the Indian population, conditions to be excluded before diagnosing IH, when to refer to specialists, investigations in a suspected case of IH and choice of therapies for its management.

Fifteen-minute consultation: Approach to the adolescent presenting with hirsutism

Hirsutism, unwanted terminal hair growth in androgen-dependent areas, is a common presentation to general paediatricians, dermatologists and endocrinologists. Polycystic ovarian syndrome is the most common cause but can be challenging to diagnose in young people due to the significant overlap of features with the healthy adolescent population. There are other rare, but important, causes to consider such as non-classic congenital adrenal hyperplasia and androgen-secreting tumours. Hirsutism carries a significant psychological burden for those living with it. This 15 min consultation piece describes the causes of hirsutism, introduces a novel assessment tool and suggests an approach to investigations and management, including signposting to psychological support.

The effect of gonadoliberin analog treatment in precocious puberty on polycystic ovarian syndrome prevalence in adulthood

Precocious puberty is diagnosed when pubertal characteristics appear before the age of 8 years in females. The most common form is gonadotropin-dependent, called axial. The primary method of treatment is administration of gonadotrophin-releasing hormone analogues (GnRHa). The aim of the study was to verify hypothesis that GnRHa therapy in the childhood may be of additive risk factor for polycystic ovary syndrome (PCOS) in adulthood.

Material and Methods

The study group consists of 24 women (median age 22 88 years, median BMI 23.5) treated with GnRHa for central precocious puberty in childhood. The control group includes 40 women (median age 23 years, median BMI 25.6) diagnosed with isolated premature thelarche and not using GnRHa in the childhood. Anthropometric measurements, ultrasound examination of minor pelvis and hormonal profile were performed. PCOS diagnosis was based on Rotterdam criteria.

Results

The study confirmed a higher prevalence of PCOS in the study group (50%) than in the control group (10%); p=0.0006. Significant, linear correlation between free testosterone levels and ovarian size was found in the study group (R=0.45 p= 0.03).

Conclusions

GnRHa therapy during childhood may have a potential influence on incidence of PCOS in the adulthood. Therefore, in this group of patients long-term follow-up focused on screening for PCOS would seem beneficial.

Non-syndromic and Syndromic Severe Acne in Adolescent Patients

Acne is a common skin disorder in adolescents. However, severe acne that is persistent and refractory to conventional treatment or has other associated symptoms should raise suspicion for non-syndromic or syndromic acne.

Body mass index evolution and ovarian function in adolescent girls who received GnRH agonist treatment for central precocious puberty or early and fast puberty

OBJECTIVES

Gonadotropin-releasing hormone agonist (GnRHa) has been used for central precocious puberty (CPP) or early and fast puberty. It was aimed to assess changes in body mass index (BMI), polycystic ovary syndrome (PCOS) frequency, and anti-Müllerian hormone (AMH) in girls who had been treated with GnRHa.

METHODS

Fifty-eight adolescent girls treated with GnRHa for CPP or early and fast puberty (3.75 mg/28 days), between 2011 and 2015, were re-evaluated in 2020-2022 at least 2 years after menstruation. Hormonal analyses were compared with 51 healthy adolescents.

RESULTS

In the GnRHa-treated group, a statistically significant increase was observed when the BMI standard deviation score (SDS) at the beginning of the treatment was compared with the BMI SDS at the end of the treatment (p=0.038). A statistically significant decrease was observed when the BMI SDS at the end of the treatment was compared with the BMI SDS in late adolescence (p=0.012). When the BMI SDS at the beginning of the treatment was compared with the BMI SDS in late adolescence, it was observed that there was no statistically significant difference (p=0.196). Of the 58 girls in the GnRHa-treated group, 8 (14 %) had PCOS. Serum AMH levels did not differ between the GnRHa-treated and the control group.

CONCLUSIONS

GnRHa treatment causes no adverse effect on BMI, at least in late adolescence. Girls treated with GnRHa were not found to be prone to developing PCOS. AMH levels were similar in the GnRHa-treated group as in the control group.

Hyperandrogenism

Hyperandrogenism is a common condition encountered by pediatric and adolescent physicians. Most girls with hyperandrogenism represent physiological pubertal variation; pathology may be present in a substantial minority. Systematic evaluation is essential to avoid unnecessary work-up in physiological causes while not missing pathological causes. Polycystic ovarian syndrome (PCOS), unexplained, persistent hyperandrogenism of ovarian origin, is the most common form in adolescent girls. The high prevalence of physiological peripubertal hirsutism, anovulation, and polycystic ovarian morphology results in mislabeling many girls as having the polycystic ovarian syndrome, a disorder with lifelong implications. The use of strict criteria of age-specific anovulation, hyperandrogenism, and duration is essential to reduce their stigmatization. The exclusion of secondary causes by screening tests (cortisol, thyroid profile, prolactin, and 17OHP) is essential before undertaking treatment for PCOS. Lifestyle measures, estrogen-progesterone preparations, antiandrogens, and metformin are the cornerstone of managing the disorder.

Polycystic ovary syndrome and body image concerns during adolescence

PURPOSE

This study aimed to compare body image concerns in adolescents with and without PCOS.

DESIGN AND METHODS

This cross-sectional study included 1076 adolescents, including 344 with PCOS and 732 without PCOS. The participants were asked to complete a comprehensive questionnaire that included demographic and reproductive parameters and the body image concerns inventory (BICI) which comprised two factors (1-dissatisfaction and embarrassment about one's appearance and 2-social function due to appearance concerns). Linear regression analysis was conducted to evaluate the effect of hyperandrogenism and/or abnormal uterine bleeding (AUB) and/or obesity on BICI and its domains both before and after adjustment for potential confounders.

RESULTS

The result showed that adolescents with PCOS had a worse total BICI score and its domains (p < 0.05). In multivariable-adjusted regression models, adolescents with PCOS were more likely to have a high body image concern (β = 0.05, P < 0.001), while those with high household income were less likely to have body image concern (β = -0.08, P = 0.004). Considering hyperandrogenism status, those with high household income were also less likely to have high body image concern (β = -0.08, P = 0.004), and age of menarche (β = -0.01, P = 0.013) were also inversely associated with total BICI score. Likewise, considering obese status, only high household income (β = -0.08, P = 0.004) was inversely associated with total BICI score. Also, considering menstrual irregularity status, high household income (β = -0.08, P = 0.005), and age of menarche (β = -0.01, P = 0.01) were inversely associated with the total BICI score.

CONCLUSION

Adolescents with PCOS had higher body image concerns. Apart from the being PCOS label, abnormal uterine bleeding was also a predictor of body image concern.

PRACTICAL IMPLICATIONS

Clinicians should pay attention to the greater influence of the PCOS label on altered body image in adolescents.

The diagnostic experience of polycystic ovary syndrome: A scoping review of patient perspectives

OBJECTIVE

Polycystic Ovary Syndrome (PCOS) is a common endocrine condition with a complex diagnostic process. The present study aims to understand patient perceptions of the process of PCOS diagnosis, and how challenges during diagnosis can influence patient understanding of PCOS and trust in healthcare providers (HCPs).

METHODS

A scoping review framework was followed. Six databases were searched for patient experiences of PCOS diagnosis, between January 2006 - July 2021. Data extraction and thematic analyses were conducted.

RESULTS

Of the 338 studies screened, 21 studies fulfilled the inclusion criteria. Patient experiences of the diagnostic process were stratified into three themes: emotional, negotiating, and incomplete. As a result of these experiences, patients begin to perceive their HCPs as lacking knowledge and empathy.

CONCLUSION

There are prevailing gaps in how PCOS diagnostic criteria are understood and applied in the clinical setting, leading to a lengthy diagnostic process. Additionally, poor HCP communication negatively affects patient trust in HCPs.

PRACTICE IMPLICATIONS

Practicing patient-centered care and empowering patients by addressing their specific information needs are essential to improving the diagnostic experience and care of individuals living with PCOS. These recommendations may also apply to the diagnosis of other complex chronic conditions.

Adolescents' polycystic ovary syndrome health-related quality of life questionnaire (APQ-20): development and psychometric properties

Several health-related quality of life (HRQOL) questionnaires for adults with polycystic ovary syndrome (PCOS) have been developed so far. However, an adolescent-specific HRQOL questionnaire for PCOS patients is still lacking. Hence, this study aimed to develop and validate a questionnaire to assess HRQOL in adolescents with PCOS. This mixed-method study was conducted in Tehran, Iran, from 2018 to 2020. The qualitative phase was conducted on 18 target participants, and in the quantitative phase, exploratory factor analysis (EFA) was performed on 200 adolescents with PCOS and confirmatory factor analyses (CFA) on the other 200 ones. The item-developing process was finalized with 77 questions. Concerning the optimum cutoff of content validity ratio, content validity index, kappa statistic coefficient, and item impact score, a draft with 55 items was finalized. Then, piloting scale was performed on 40 participants and considering the interitem correlation < 0.3, fifteen items were excluded. Based on the EFA, 20 items in six components (emotion and mood, loss of attractiveness due to the hirsutism, loss of attractiveness due to the acne, self-care, support, and menstrual cycle problem) that explain 60.3% of the variance were extracted. The CFA with acceptable values of goodness-of-fit statistics supports this construct validity. Results of reliability, floor, and ceiling effect were acceptable.  Conclusion: Our study showed that the short questionnaire of APQ-20 is valid and reliable for assessment of the HRQOL of adolescents with PCOS. Further studies are needed to assess the feasibility and reliability of APQ-20 for assessing the HRQOL of adolescents with PCOS. It constitutes a significant step forward in the measurement of HRQOL of adolescents with PCOS. What is Known: • There is no disease-specific questionnaire for assessment of the health-related quality of life (HRQOL) of adolescents with polycystic ovary syndrome (PCOS). What is New: • The short questionnaire of APQ-20 is easy to use, valid, and reliable for the assessment of the HRQOL of adolescents with PCOS. • APQ-20 constitutes a significant step forward in the measurement of HRQOL of adolescents with PCOS.

The Implication of Mechanistic Approaches and the Role of the Microbiome in Polycystic Ovary Syndrome (PCOS): A Review

As a complex endocrine and metabolic condition, polycystic ovarian syndrome (PCOS) affects women's reproductive health. These common symptoms include hirsutism, hyperandrogenism, ovulatory dysfunction, irregular menstruation, and infertility. No one knows what causes it or how to stop it yet. Alterations in gut microbiota composition and disruptions in secondary bile acid production appear to play a causative role in developing PCOS. PCOS pathophysiology and phenotypes are tightly related to both enteric and vaginal bacteria. Patients with PCOS exhibit changed microbiome compositions and decreased microbial diversity. Intestinal microorganisms also alter PCOS patient phenotypes by upregulating or downregulating hormone release, gut-brain mediators, and metabolite synthesis. The human body's gut microbiota, also known as the "second genome," can interact with the environment to improve metabolic and immunological function. Inflammation is connected to PCOS and may be caused by dysbiosis in the gut microbiome. This review sheds light on the recently discovered connections between gut microbiota and insulin resistance (IR) and the potential mechanisms of PCOS. This study also describes metabolomic studies to obtain a clear view of PCOS and ways to tackle it.

The Burden of Non-Alcoholic Fatty Liver Disease in Adolescents with Polycystic Ovary Syndrome: A Case-Control Study

The aim of this case-control study was to assess the burden of non-alcoholic fatty liver disease (NAFLD) in adolescents with polycystic ovary syndrome (PCOS) and its associations with insulin resistance, hyperandrogenism, and other metabolic characteristics of the syndrome. A total of 87 Caucasian adolescent girls (47 with PCOS and 40 controls), aged 12.3-20.4 years, underwent blood sampling for glucose metabolism, hormonal and lipid profile, gynecological and liver ultrasound, and liver elastography. Indices of insulin resistance, liver steatosis, and liver fibrosis were calculated. NAFLD diagnosed by ultrasound was more prevalent in adolescents with PCOS than controls (22.7% vs. 6.1%, p = 0.046), and was also verified by liver steatosis indices. The latter was not apparent for hepatic fibrosis, as assessed by Fibroscan^® and calculated indices. The homeostatic model assessment for insulin resistance (HOMA-IR) was found to predict NAFLD diagnosis by the liver fat score (LFS) index (β = 0.709, p = 0.002). Adolescents with PCOS and high free androgen index (FAI) presented worse NAFLD than those adolescents with PCOS and lower FAI. In addition, adolescents with PCOS and concurrent NAFLD had worse insulin sensitivity indices (HOMA-IR, QUICKI, and glucose to insulin ratio) than adolescents with PCOS alone. Adolescent insulin resistance could be considered a confounder of the association between PCOS and NAFLD.

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.

Correlation study on serum miR-222-3p and glucose and lipid metabolism in patients with polycystic ovary syndrome

Objective

microRNAs (miRNAs) play pivotal roles in polycystic ovary syndrome (PCOS), an endocrine and metabolic disorder that commonly occurs in women of childbearing age. This paper aimed to measure miR-222-3p expression in sera of PCOS patients and to explore its clinical value on PCOS diagnosis and prediction of diabetic and cardiovascular complications.

Methods

Totally 111 PCOS patients and 94 healthy people were recruited and assigned to the overweight (ow) group and non-overweight (non-ow) group, followed by determination of serum miR-222-3p expression. The diagnostic efficiency of miR-222-3p on PCOS ow and non-ow patients was analyzed. Correlations between miR-222-3p and glycolipid metabolic indicators and diabetic and cardiovascular complications in PCOS were analyzed. The downstream target of miR-222-3p was predicted and their binding relationship was verified. The correlation between PGC-1α and miR-222-3p was analyzed.

Results

miR-222-3p was highly-expressed in PCOS patients (p < 0.001), in especially PCOS ow patients. The area under the curve (AUC) of miR-222-3p diagnosing PCOS non-ow patients was 0.9474 and cut-off value was 1.290 (89.06% sensitivity, 98.11% specificity), indicating that non-ow people with serum miR-222-3p > 1.290 could basically be diagnosed with PCOS. AUC of miR-222-3p diagnosing PCOS ow patients was 0.9647 and cut-off value was 2.425 (85.11% sensitivity, 100% specificity), suggesting that ow people with serum miR-222-3p > 2.425 could basically be diagnosed with PCOS. miR-222-3p was positively-correlated with fasting plasma glucose (FPG), fasting insulin (FINS), homeostatic model assessment–insulin resistance (HOMA-IR), and low-density lipoprotein cholesterol (LDL-C) and negatively-correlated with high-density lipoprotein cholesterol (HDL-C). miR-222-3p was independently-correlated with diabetic and cardiovascular complications in PCOS (p < 0.05). High expression of miR-222-3p predicted high risks of diabetic and cardiovascular complications in PCOS. miR-222-3p targeted PGC-1α and was negatively-correlated with PGC-1α (r = − 0.2851, p = 0.0224; r = − 0.3151, p = 0.0310).

Conclusion

High expression of miR-222-3p assisted PCOS diagnosis and predicted increased risks of diabetic and cardiovascular complications. miR-222-3p targeted PGC-1α and was negatively-correlated with PGC-1α.

The Interaction of Obesity and Reproductive Function in Adolescents

Obesity is increasing worldwide, including in pediatrics. Adequate nutrition is required for initiation of menses, and there is a clear secular trend toward earlier pubertal onset and menarche in females in countries around the globe. Similar findings of earlier pubertal start are suggested in males. However, as individuals and populations have crossed into over-nutritional states including overweight and obesity, the effect of excess weight on disrupting reproductive function has become apparent. Hypothalamic hypogonadism and polycystic ovary syndrome are two conditions where reproductive function appears to directly relate to excess weight. Clinical findings in individuals with certain polygenic and monogenic obesity syndromes, which also have reproductive disruptions, have helped elucidate neurologic pathways that are common to both. Clinical endocrinopathies such as hypothyroidism or panhypopituitarism also aide in the understanding of the role of the endocrine system in weight gain. Understanding the intersection of obesity and reproductive function may lead to future therapies which can treat both conditions.

Effects of high-intensity interval training and strength training on levels of testosterone and physical activity among women with polycystic ovary syndrome

Objective

Polycystic ovary syndrome is a diverse endocrine disorder characterized by hyperandrogenism and ovulatory dysfunction. Hyperandrogenism affects body morphology, resulting in excess weight (overweight or obesity). This study aimed to evaluate the efficacy of high-intensity interval training on serum testosterone levels, body fat percentage, and level of physical activity among women with polycystic ovary syndrome.

Methods

Fifty participants were enrolled in the study and randomly allocated into two groups. Group A performed high-intensity interval training on alternate days per week (total of 12 weeks) and group B performed strength training on alternate days per week (total of 12 weeks). Baseline and 12th-week assessments included serum testosterone levels, body fat percentage using the skinfold method, and level of physical activity assessed using the International Physical Activity Questionnaire.

Results

After 12 weeks of intervention, both groups showed significant improvements in all the outcomes. However, group A (high intensity interval training) showed statistically significant results compared to group B (strength training) in lowering serum testosterone levels (P=0.049) and body fat percentage (P=0.001) and increasing physical activity levels (P=0.006).

Conclusion

After 12 weeks of exercise, both exercises benefited the participants; however, high-intensity interval training specifically was found to be a more effective exercise regimen than strength training in reducing serum testosterone levels and body fat percentage and enhancing levels of physical activity in women with polycystic ovary syndrome.

Effect of the presence of polycystic ovary syndrome-related features on anti-Mullerian hormone and androstenedione levels in adolescents with or without menstrual irregularity

PURPOSE

To determine the variation in anti-Mullerian hormone (AMH) and androstenedione (A4) concentrations in adolescent girls, with or without menstrual cycle disorder in relation to phenotypic features of. PCOS.

METHODS

Adolescent girls (n = 129), age range 14-19 years, were recruited in the cohort study. All participants were in the 4th or 5th year after menarche. Sixty-eight had menstrual irregularities, usually oligomenorrhea (OM), and 61 had regular menstruation (RM). AMH and A4 concentrations were measured. Hirsutism was recorded. Polycystic ovarian morphology (PCOM) was evaluated by transabdominal pelvic ultrasonography. Polycystic ovary syndrome (PCOS) features were defined according to Rotterdam consensus criteria.

RESULTS

AMH and A4 were significantly higher in adolescent girls with OM than in girls with RM (p < 0.05). A4 and body mass index (BMI) of adolescents with OM was significantly higher in those with hirsutism than those without hirsutism (p = 0.01 and 0.008, respectively). There was a positive correlation between A4 and BMI (r: 0.327, p < 0.01). Logistic regression showed that the frequency of OM in the presence of PCOM was 10.8 times (95% CI 2.04-12.09) compared to those without PCOM. The highest AMH concentrations were found in girls with OM, hirsutism, and PCOM (p < 0.05).

CONCLUSIONS

AMH and A4 are elevated in adolescents with oligomenorrhoea. High A4 is more prominent in the presence of hirsutism and is associated with increased BMI. PCOM, increases the likelihood of oligomenorrhea by about 10 times. AMH increase as the combination of clinical features of PCOS increases in adolescents with menstrual irregularity.

Muscle-to-Fat Ratio for Predicting Metabolic Syndrome Components in Children with Overweight and Obesity

Background: Pediatric obesity has been linked to the components of metabolic syndrome (MetS: abdominal obesity, atherogenic dyslipidemia, elevated blood pressure, and insulin resistance). Data on the role of muscle mass in the development of MetS are sparse. We explored the interaction between the muscle-to-fat ratio (MFR) and MetS components in children with overweight or obesity. Methods: An observational study of 210 pediatric subjects (88 boys, mean age [±standard deviation (SD)] 11.9 ± 3.1 years, BMI z-score range 1.036-3.140) from January 2018 to January 2021. Body composition was measured by bioelectrical impedance analysis (Tanita MC-780 MA and GMON Professional Software), and MFR z-scores were calculated. Results: The 148 subjects (70%) who had MetS components were older (p = 0.008), had lower socioeconomic positions, higher triglyceride/high-density lipoprotein-cholesterol ratios, fat percentages (FATP), truncal FATPs (TRFATPs), and lower MFR z-scores (p < 0.001 for all parameters) than those without MetS components. The correlation between the MFR z-score and the BMI z-score was stronger in subjects with obesity than in subjects with overweight (r = -0.556 vs. r = -0.440, p < 0.001 for both). The risk for MetS components increased by 1.4 for every 3% increase in FATP or TRFATP [odds ratio (OR) = 1.4, confidence interval ([CI] 1.20, 1.64), p < 0.001]. The risk for MetS components was tripled for every 1 SD decrease in MFR z-scores [OR = 3.3, CI (1.74, 6.27), p < 0.001]. Conclusions: Given the strong predictive value of the MFR z-score in the development of early-onset MetS components, preventive strategies should apply interventions for improving the body composition parameters of both adiposity and muscle.

Present and Future: Crosstalks Between Polycystic Ovary Syndrome and Gut Metabolites Relating to Gut Microbiota

Polycystic ovary syndrome (PCOS) is a common disease, affecting 8%-13% of the females of reproductive age, thereby compromising their fertility and long-term health. However, the pathogenesis of PCOS is still unclear. It is not only a reproductive endocrine disease, dominated by hyperandrogenemia, but also is accompanied by different degrees of metabolic abnormalities and insulin resistance. With a deeper understanding of its pathogenesis, more small metabolic molecules, such as bile acids, amino acids, and short-chain fatty acids, have been reported to be involved in the pathological process of PCOS. Recently, the critical role of gut microbiota in metabolism has been focused on. The gut microbiota-related metabolic pathways can significantly affect inflammation levels, insulin signaling, glucose metabolism, lipid metabolism, and hormonal secretions. Although the abnormalities in gut microbiota and metabolites might not be the initial factors of PCOS, they may have a significant role in the pathological process of PCOS. The dysbiosis of gut microbiota and disturbance of gut metabolites can affect the progression of PCOS. Meanwhile, PCOS itself can adversely affect the function of gut, thereby contributing to the aggravation of the disease. Inhibiting this vicious cycle might alleviate the symptoms of PCOS. However, the role of gut microbiota in PCOS has not been fully explored yet. This review aims to summarize the potential effects and modulative mechanisms of the gut metabolites on PCOS and suggests its potential intervention targets, thus providing more possible treatment options for PCOS in the future.

Melatonin alleviates insulin resistance through the PI3K/AKT signaling pathway in ovary granulosa cells of polycystic ovary syndrome

Polycystic ovary syndrome (PCOS) is a common endocrine gynecological disorder. Insulin resistance (IR) is a major cause of PCOS. Melatonin, a critical endogenous hormone, has beneficial effects on the female reproductive system. This study aims to investigate the molecular effect of melatonin on IR in human ovarian granulosa cells (GCs). Hormone levels of the subjects were determined through clinical examination. The expression levels of insulin receptor substrate (IRS)-1 and glucose transporter (GLUT4) in GCs from PCOS patients and a human granulosa cell line (SVOG) were examined using qRT-PCR and western blot. The IR cell model was established by inducing SVOG cells with palmitic acid (PA). IR was detected in GCs of PCOS patients and SVOG by measuring glucose content and glucose uptake. Cell viability and apoptosis levels were detected by CCK-8 assay and flow cytometry. PI3K/Akt pathway expression in SVOG was assessed by western blot. PCOS patients had higher levels of luteinizing hormone (LH), testosterone, and LH/follicle-stimulating hormone. PA decreased cell viability, promoted apoptosis, and reduced glucose uptake in SVOG cells. IRS-1 and GLUT4 mRNA and protein expression was downregulated, and glucose uptake capacity was reduced in PCOS GCs and SVOG cells. Melatonin significantly upregulated IRS-1 and GLUT4 expression, downregulated p-IRS-1 (Ser307), and improved glucose uptake in PCOS patients' GCs and SVOG cells. PA decreased PI3K and Akt phosphorylation, whereas melatonin increased p-PI3K and p-Akt levels. Melatonin can reduce IR in GCs and PA-induced SVOG cells via the PI3K/Akt signaling pathway, providing more evidence for treating polycystic ovary syndrome.

Prevalence and Cutaneous Comorbidity of Acne Vulgaris in the Working Population

Purpose

Although acne vulgaris (AV) is a common disease and can persist into adulthood, there are few large-scale epidemiological studies on the prevalence of acne vulgaris in adults. The aim of our study was to characterise the epidemiology and comorbidity of acne vulgaris in working adults in Germany.

Patients and Methods

Within the framework of a cross-sectional study, a total of 161,269 employees underwent dermatological whole-body examinations in more than 500 German companies between 2001 and 2016. Point prevalence rates for acne vulgaris and further skin diseases and their 95% confidence intervals were calculated and differences between participants with and without acne vulgaris were tested with chi-squared tests.

Results

Mean age was 43.2 years ± 10.9, 55.5% were male. In total, n = 5311 people (3.3%) with acne vulgaris were identified. Prevalence decreased by age. Controlling for age and gender, acne was significantly associated with folliculitis (OR = 1.91; CI: 1.76–2.07), contact dermatitis (OR = 1.74; CI: 1.08–2.81), rosacea (OR = 1.74; CI: 1.40–2.15), pyoderma (OR = 1.58; 1.22–2.06), seborrheic dermatitis (OR = 1.47; CI: 1.27–1.71), hand eczema (OR = 1.34; CI: 1.00–1.76), verruca vulgaris plantaris (OR = 1.29; CI: 1.09–1.51), tinea pedis (OR = 1.27; CI: 1.10–1.47), spider veins (OR = 1.26; CI: 1.16–1.38) and telangiectasia (OR = 1.15; CI: 1.02–1.30).

Conclusion

These data underline the importance of acne vulgaris in the adult population. Further studies to better understand the pathophysiology of AV and its comorbidity in different phases of adulthood would be desirable to develop appropriate guidelines and therapy concepts.

Adipokine levels and carbohydrate metabolism in patients diagnosed de novo with polycystic ovary syndrome

INTRODUCTION

Central obesity appears to play a major role in the pathogenesis of metabolic disorders in polycystic ovary syndrome. Insulin resistance and carbohydrate disorders are associated with dysfunctional secretion of various adipokines by the adipose tissue.

OBJECTIVES

This study aimed to evaluate leptin, apelin, and visfatin against a background of carbohydrate metabolism parameters in patients diagnosed de novo with polycystic ovary syndrome (PCOS).

MATERIAL AND METHODS

The study group consisted of 40 patients with PCOS (mean age, 29 years) diagnosed in accordance with the American Society for Reproductive Medicine criteria from 2003. The control group consisted of 37 clinically healthy women (mean age, 26 years). All controls had regular menses and no clinical or biochemical signs of hyperandrogenism. Concentrations of leptin, apelin, visfatin, and insulin were measured by immunoenzymatic methods. Glucose concentrations were determined using spectrophotometry.

RESULTS

Significantly higher concentrations of leptin, insulin, homeostatic model assessment for insulin resistance (HOMA-IR) index, and the immunoreactive insulin (IRI)/glucose index were found in the PCOS group than in the control group. Notably, the concentration of apelin was over five times lower in the PCOS group than in the control group. In patients with PCOS, a positive correlation was found between the concentrations of insulin and leptin and concentrations of leptin and IRI/glucose. Patients of the PCOS group with body mass index (BMI) ≥  25 had significantly higher values of leptin, insulin, HOMA-IR index, and IRI/glucose index than patients of the PCOS group with normal BMI. In the PCOS group, a positive correlation was found between BMI and leptin concentration (r = 0.7176; p < 0.0001) and carbohydrate metabolism, such as insulin (r = 0.5524; p = 0.0003), glucose (r = 0.3843; p = 0.0157), HOMA-IR (r = 0.5895; p < 0.0001), and IRI/glucose (r = 0.3872; p = 0.0163). These findings were not observed in the control group.

CONCLUSIONS

(1) Increased leptin concentration observed in women diagnosed de novo with PCOS as well as positive correlations between leptin and HOMA-IR, and IRI/glucose and BMI may indicate a potential role of leptin in the reduction of tissue sensitivity to insulin. (2) Significantly lower apelin concentration in the PCOS group (>5 fold) than in the control group, associated with a concomitant increase in leptin, may also contribute to carbohydrate metabolism disorders occurring in the course of PCOS.

Diagnosis and treatment of polycystic ovary syndrome in adolescents

ABSTRACT

Polycystic ovary syndrome (PCOS), characterized by ovulatory dysfunction and hyperandrogenism, is one of the most common endocrine disorders in women of reproductive age. Early diagnosis can help clinicians address associated long-term metabolic and reproductive health complications and mitigate the negative effects of PCOS on a patient's mental health and quality of life. Clinicians often are challenged by the diagnosis and management of PCOS because of controversies around diagnostic criteria, especially for adolescents. The International Consortium of Paediatric Endocrinology 2017 Consensus Statement provides practical guidance for clinicians to implement best practices for the identification, diagnosis, and management of PCOS in adolescents.

Dietary and Physical Activity Habits in Adolescent Girls with Polycystic Ovary Syndrome (PCOS)-HAstudy

The role of inappropriate lifestyle in the etiology of polycystic ovary syndrome (PCOS) and its metabolic and reproductive complications has attracted much attention in recent years; however, most studies involve adult patients. Thus, the study aimed to compare dietary patterns, physical activity, metabolic, anthropometric and inflammatory markers of 14-18-year-old girls with and without PCOS (n = 61 and n = 35, respectively) as well as to assess correlations between concentrations of metabolic and inflammatory markers and macronutrient intake and to identify the independent predictors of PCOS, related to diet and physical activity (PA). Compared to the control group, PCOS girls consumed significantly more total fat (p = 0.0005), including both saturated (SFA) (p = 0.03), monounsaturated (MUFA) (p = 0.0003) and polyunsaturated fatty acids (PUFA) (p = 0.01). A significantly higher percentage of PCOS patients consumed high and medium glycemic index (GI) foods (p = 0.03) and represented a low level of PA, both during school and in leisure time (41.67 vs. 6.06%; p = 0.0001 and 32.79 vs. 5.71%; p = 0.003, respectively). The PCOS group had also significantly higher waist circumference (WC), C-reactive protein (CRP) (p = 0.01), LDL cholesterol (p = 0.01), fasting insulin (p = 0.002) and HOMA-IR (p = 0.006) levels. There was an inverse correlation between fiber intake and fasting insulin, (p = 0.0002, r = -0.37), HOMA-IR (p = 0.0004, r = -0.35), WC (p = 0.029; r = -0.222) and a positive relationship between high and medium GI diet and insulin concentration (p = 0.003; r = 0.3). An increase of 10 g/day in total fat intake per day increases the probability of PCOS by 1.4 times. If the SFA or MUFA intakes increase by 10 g, the probability of PCOS increase 1.7-fold and 2.5-fold, respectively. The consumption of foods with a medium GI raises the probability of PCOS by more than 3 times, after adjusting for age. The odds ratio decreased for the moderate and high PA at school/work and in leisure time. Further research in girls with PCOS is needed to test whether low GI and dietary fatty acid reduction combined with increased PA is effective in the nonpharmacological treatment and prevention of PCOS complications.

Decreased SFRP5 correlated with excessive metabolic inflammation in polycystic ovary syndrome could be reversed by metformin: implication of its role in dysregulated metabolism

Background

Polycystic Ovary Syndrome (PCOS) is a complex endocrine disorder of heterogeneous nature. Secreted frizzled-related protein (SFRP) 5 is an anti-inflammatory adipokine implicated in metabolic homeostasis. We aimed to confirm the correlation between SFRP5, metabolic inflammation and PCOS, investigate the predictive value of SFRP5 for PCOS and the involvement of SFRP5 in metformin treated PCOS.

Methods

This retrospective case–control study included 140 PCOS and 33 control women. Sixty seven PCOS women were included for detecting serum SFRP5 level and its correlation with metabolic inflammation. Predictive value of SFRP5 for PCOS was evaluated by logistic regression and receiver operating characteristic (ROC) analyses. Seventy three PCOS women complicated with impaired glucose tolerance (IGT)/insulin resistance (IR) were included for investigating the effects of metformin (37 with metformin vs. 36 without metformin) on SFRP5, pro-inflammatory cytokines, ovulation and pregnancy rate.

Results

Plasma SFRP5 levels were decreased in PCOS (odds ratio: 0.78, 95% confidence interval (CI):0.703–0.866, P < 0.001) independent of obesity. SFRP5 was negatively associated with IL-6, TNFα, FAI and HOMA-IR. The cut-off point of SFRP5 < 46.13 ng/ml was optimal to identify PCOS with a higher specificity of 96.87% and a relatively lower sensitivity compared to AMH. SFRP5 increased specificity of AMH for predicting PCOS, especially which with relatively decreased AMH (< 4.7 ng/ml). Metformin promoted SFRP5 and decreased leptin, IL-6 and TNFα secretion in PCOS women with metabolic abnormality in a time dependent manner and with improved ovulation rate and pregnancy rate.

Conclusion

Decreased SFRP5 was associated with metabolic inflammation in PCOS and has a potential role for the supplement of AMH in predicting PCOS. The reverse of serum SFRP5 by metformin indicated that SFRP5 participated in the improvment of follicular development by metformin. Further prospective investigations are needed to confirm these preliminary data.

Approach to the Virilizing Girl at Puberty

Virilization is the medical term for describing a female who develops characteristics associated with male hormones (androgens) at any age, or when a newborn girl shows signs of prenatal male hormone exposure at birth. In girls, androgen levels are low during pregnancy and childhood. A first physiologic rise of adrenal androgens is observed at the age of 6 to 8 years and reflects functional activation of the zona reticularis of the adrenal cortex at adrenarche, manifesting clinically with first pubic and axillary hairs. Early adrenarche is known as "premature adrenarche." It is mostly idiopathic and of uncertain pathologic relevance but requires the exclusion of other causes of androgen excess (eg, nonclassic congenital adrenal hyperplasia) that might exacerbate clinically into virilization. The second modest physiologic increase of circulating androgens occurs then during pubertal development, which reflects the activation of ovarian steroidogenesis contributing to the peripheral androgen pool. However, at puberty initiation (and beyond), ovarian steroidogenesis is normally devoted to estrogen production for the development of secondary female bodily characteristics (eg, breast development). Serum total testosterone in a young adult woman is therefore about 10- to 20-fold lower than in a young man, whereas midcycle estradiol is about 10- to 20-fold higher. But if androgen production starts too early, progresses rapidly, and in marked excess (usually more than 3 to 5 times above normal), females will manifest with signs of virilization such as masculine habitus, deepening of the voice, severe acne, excessive facial and (male typical) body hair, clitoromegaly, and increased muscle development. Several medical conditions may cause virilization in girls and women, including androgen-producing tumors of the ovaries or adrenal cortex, (non)classical congenital adrenal hyperplasia and, more rarely, other disorders (also referred to as differences) of sex development (DSD). The purpose of this article is to describe the clinical approach to the girl with virilization at puberty, focusing on diagnostic challenges. The review is written from the perspective of the case of an 11.5-year-old girl who was referred to our clinic for progressive, rapid onset clitoromegaly, and was then diagnosed with a complex genetic form of DSD that led to abnormal testosterone production from a dysgenetic gonad at onset of puberty. Her genetic workup revealed a unique translocation of an abnormal duplicated Y-chromosome to a deleted chromosome 9, including the Doublesex and Mab-3 Related Transcription factor 1 (DMRT1) gene.

LEARNING OBJECTIVES

Identify the precise pathophysiologic mechanisms leading to virilization in girls at puberty considering that virilization at puberty may be the first manifestation of an endocrine active tumor or a disorder/difference of sex development (DSD) that remained undiagnosed before and may be life-threatening. Of the DSDs, nonclassical congenital adrenal hyperplasia occurs most often.Provide a step-by-step diagnostic workup plan including repeated and expanded biochemical and genetic tests to solve complex cases.Manage clinical care of a girl virilizing at puberty using an interdisciplinary team approach.Care for complex cases of DSD manifesting at puberty, such as the presented girl with a Turner syndrome-like phenotype and virilization resulting from a complex genetic variation.

Evaluation the Role of Ghrelin and Leptin as Biochemical Marker in Female with Polycystic Ovarian Syndrome

INTRODUCTION

Polycystic ovary syndrome (PCOS) is the most common endocrine disorder in women of reproductive age. PCOS is a heterogeneous complex disorder of unwell defined aetiology. Some studies report its association to various endocrine, metabolic and immunological abnormalities. The hunger hormones ghrelin and leptin affect the pathogenesis of PCOS and might lead to the development of metabolic syndrome (MS) in obese women.

AIM

The study aims at evaluating the role of ghrelin and leptin level in female with poly cystic ovary syndrome as a biochemical marker for the diagnosis and monitoring progression.

SUBJECTS AND METHODS

The study including one hundred PCOS patients and fifty apparently healthy subjects with regular menstrual cycle, visiting gynecology outpatient clinic of Kalar General Hospital, from the beginning of February 2015 to the end of June 2015. Body mass index (BMI) along with serum ghrelin, leptin, Luteinizing hormone (LH), Follicle stimulating hormone (FSH) and testosterone levels were measured for both groups. Serum leptin was determined using sandwich ELISA, while serum ghrelin was determined using competitive ELISA. Differences between patient and control groups were tested by using t-test. Also one way Anova was used to test the relation among different groups.

RESULTS

There was a significant decrease in ghrelin level and increase in leptin levels in women with PCOS when compared with control group. Also there was a significant elevation in serum level of LH ,Testosterone , Prolactin and decrease in serum FSH in PCOS patients when compared to control group. Additionally, serum ghrelin decreased and serum leptin level increased significantly in women with PCOS compared to controls in all age and BMI groups.

CONCLUSION

The significant decrease in ghrelin and increased in leptin in PCOS patients than in controls indicated that they are at high risk for metabolic syndrome development.

Regenerative Medicine Perspectives in Polycystic Ovary Syndrome

Polycystic ovary syndrome (PCOS) is the most common gynecologic endocrine disorder in women between the ages of 15 and 40, with uncertain etiology. It is mostly presented with hyperandrogenism and insulin resistance along with a variety of comorbidities that significantly reduce a patient's quality of life. Many disturbed metabolic pathways are correlated with PCOS. Moreover, it is evident that there is a strong genetic factor for PCOS. Indeed, several altered gene expressions have been found in PCOS subjects, but the exact genetic origins are still unclear. The major treatment options such as pharmacological treatments are to improve the symptoms. In addition, surgical procedures (Bariatric surgery and assisted reproductive technologies) can be used to treat some of the patient's complications and reduce their severity. Generally, using pharmacological agents for a long period of time can increase the risk of adverse effects. Moreover, surgical options may have high-risk consequences. Herein, there is an undeniable need for a different multidisciplinary approach to PCOS. Regenerative medicine with the help of stem cells can develop a worthy alternative approach for the treatment of PCOS. Furthermore, animal models can provide valuable knowledge of genetic alterations and metabolic pathway disturbances in PCOS. They can also be used for testing novel treatments in pre-clinical stages. Therein, the current knowledge of PCOS and investigation about the potential role of regenerative medicine in developing new and more efficient treatments for PCOS are summarized here.

A Systematic Review of Anogenital Distance and Gynecological Disorders: Endometriosis and Polycystic Ovary Syndrome

BACKGROUND AND AIM

Anogenital distance (AGD) can serve as a life-long indicator of androgen action in gestational weeks 8-14. AGD has been used as an important tool to investigate the exposure to endocrine-disrupting compounds in newborns and in individuals with male reproductive disorder. Endometriosis and polycystic ovary syndrome (PCOS) are two common gynecological disorders and both are related to prenatal androgen levels. Therefore, we performed a systematic review to evaluate the relationships of AGD with these gynecological disorders.

METHODS

PubMed, Web of Science, and Embase were searched for published studies up to January 25, 2021. No language restriction was implemented.

RESULTS

Ten studies were included in this review. Five focused on women with endometriosis, and six investigated women with PCOS. According to these studies, PCOS patients had longer AGD than controls, while endometriosis patients had shorter AGD than controls. In conclusion, this study provides a detailed and accurate review of the associations of AGD with endometriosis and PCOS.

CONCLUSION

The current findings indicate the longer AGD was related to PCOS and shorter AGD was related to endometriosis. However, further well-designed studies are needed to corroborate the current findings.

The Prevalence of Polycystic Ovary Syndrome: A Brief Systematic Review

Background:

Polycystic ovary syndrome (PCOS), the major endocrinopathy among reproductive-aged women, is not yet perceived as an important health problem in the world. It affects 4%–20% of women of reproductive age worldwide. The prevalence, diagnosis, etiology, management, clinical practices, psychological issues, and prevention are some of the most confusing aspects associated with PCOS.

Aim:

The exact prevalence figures regarding PCOS are limited and unclear. The aim of this review is to summarize comprehensively the current knowledge on the prevalence of PCOS.

Materials and Methods:

Literature search was performed through PubMed, ScienceDirect, Cochrane Library, and Google Scholar (up to December 2019). All relevant articles published in English language were identified following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines.

Results:

Our analysis yielded 27 surveys with a pooled mean prevalence of 21.27% using different diagnostic criteria. The proportion of women with PCOS also increased in the last decade.

Conclusion:

The current review summarizes and interprets the results of all published prevalence studies and highlights the burden of the syndrome, thereby supporting early identification and prevention of PCOS in order to reverse the persistent upward trend of prevalence.

Heterogeneity of Endocrinologic and Metabolic Parameters in Reproductive Age Polycystic Ovary Syndrome (PCOS) Women Concerning the Severity of Hyperandrogenemia-A New Insight on Syndrome Pathogenesis

Background: Polycystic ovary syndrome (PCOS) is characterized by hyperandrogenism, anovulation, infertility, obesity, and insulin resistance, which results in increased concentrations of testosterone (T), which disturbs follicular growth and ovulation. This study aimed to assess PCOS women’s clinical, endocrinological, and metabolic parameters concerning hyperandrogenism severity. Results: 314 women (mean age 27.3 ± 4.6; mean body mass index (BMI) 25.7 ± 5.6) with PCOS, were divided into terciles according to T concentrations: <0.64 ng/mL (group 1), 0.64 to 0.84 ng/mL (Group 2) and >0.84 ng/mL (group 3). The mean concentration of T in all women was 0.59 ng/mL and correlated negatively with the number of menstrual cycles per year (MPY) (r = −0.36; p < 0.0001) and positively with Ferriman-Gallway score (FG) (r = 0.33; p < 0.0001), luteinizing hormone (LH) (r = 0.19; p < 0.0001) and dehydroepiandrosterone sulfate (DHEAS) (r = 0.52; p < 0.0001). Positive correlation between BMI and hirsutism (r = 0.16; p < 0.0001), total cholesterol (TC) (r = 0.18; p < 0.0001), low-density lipoprotein (LDL) (r = 0.29; p < 0.0001), and triglycerides (TG) (r = 0.40; p < 0.0001) was demonstrated. The division into subgroups confirmed the lowest MPY, highest LH, and hirsutism in group 3. BMI, insulin sensitivity indices, and lipid profile parameters were not different between the three T subgroups. Conclusions: We found no correlation between testosterone levels and insulin sensitivity or dyslipidemia in women with PCOS. Metabolic abnormalities may contribute more significantly than hyperandrogenemia to PCOS development.

Characteristics of Adolescents with Differing Polycystic Ovary Syndrome Phenotypes

STUDY OBJECTIVE

To analyze clinical, metabolic, hormonal, and ultrasound characteristics of adolescents with polycystic ovary syndrome phenotypes.

DESIGN

We performed a retrospective analysis of quality improvement data. We divided patients according to phenotype on the basis of clinical or biochemical diagnosis of hyperandrogenism (HA), irregular menstruation (IM), and presence or absence of polycystic ovarian morphology (PCOM) on pelvic ultrasound (PUS) images, if obtained. The 5 resulting groups were: (1) HA/IM/normal PUS, n = 28; (2) HA/PCOM, n = 10; (3) IM/PCOM, n = 18; (4) HA/IM/PCOM, n = 40; and (5) HA/IM/no PUS obtained, n = 80. We compared parameters between groups using the nonparametric Wilcoxon rank sum test.

SETTING

Boston Children's Hospital, 2012-2016.

PARTICIPANTS

One hundred seventy-six girls and young women aged 11-25 years.

INTERVENTIONS

None.

MAIN OUTCOME MEASURES

(1) Clinical, metabolic, and hormonal characteristics; and (2) PUS measurements.

RESULTS

Groups with HA had significantly higher acne scores, Ferriman-Gallwey scores, and total and free testosterone concentrations than groups without HA. Significant differences in hemoglobin A1c were found between the IM/PCOM and HA/IM/PCOM groups (5.1% vs 5.3%; P = .01) and the IM/PCOM and HA/IM/no PUS groups (5.1% vs 5.3%; P < .01). In patients who had ultrasound performed, 49/94 (52.1%) met PCOM criteria on the basis of ovarian size, 37/94 (39.4%) on the basis of follicle number, and 27/94 (28.7%) on both; 10/94 (10.5)% had incidental findings on ultrasound, with 2 patients requiring further management.

CONCLUSION

Limited differences in clinical, metabolic, and hormonal characteristics exist between adolescents with different phenotypes of polycystic ovary syndrome, and are mostly related to the presence or absence of HA. Of patients with ultrasound examinations, only 2 had clinically actionable incidental findings.

Body Perception, Self-Esteem, and Comorbid Psychiatric Disorders in Adolescents Diagnosed with Polycystic Ovary Syndrome

STUDY OBJECTIVE

To investigate adolescents with polycystic ovary syndrome (PCOS) in terms of body perception, self-esteem, and comorbid psychiatric diseases by comparing them with their healthy peers.

DESIGN

Cross-sectional design.

SETTING

The Department of Child and Adolescent Psychiatry and the Department of Pediatric Endocrinology outpatient clinic of Cumhuriyet University in Sivas, Turkey.

PARTICIPANTS

Fifty female adolescents aged 12-18 years who were diagnosed as having PCOS and 37 healthy adolescents aged 12-18 years.

INTERVENTIONS AND MAIN OUTCOME MEASURES

All adolescents were evaluated by a child and adolescent psychiatrist using a semistructured interview (Schedule for Affective Disorders and Schizophrenia for School-Age Children) and asked to complete the Rosenberg Self-Esteem Scale, Children's Depression Inventory, and Body Image Scale.

RESULTS

The rate of psychiatric disorders in the PCOS group was significantly higher than in the control participants (16/50 (32%) vs 5/37 (13.5%), respectively; P = .046). The most common disorder was major depressive disorder. The Rosenberg Self-Esteem Scale and Body Image Scale scores of the PCOS group were lower (P = .03; P < .001, respectively), and Children's Depression Inventory scores were higher (P = .03) than in the control group. There was no significant relationship between obesity, hirsutism, and insulin resistance with any psychiatric disorders in the PCOS group.

CONCLUSION

Adolescents with PCOS had more psychopathology than their peers. Moreover, their self-esteem was lower and their body perceptions were more dissatisfied compared with their peers.

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.

Alterations in the intestinal microbiome associated with PCOS affect the clinical phenotype

Polycystic ovarian syndrome (PCOS), characterized by chronic anovulation and hyperandrogenaemia, is a complex endocrine and metabolic disorder commonly seen in women of reproductive age. Multiple factors, including the intestinal microbiome, affect the pathogenesis and development of PCOS. However, the specific mechanisms by which gut microbes play a role in PCOS remain elusive. This review summarizes recent research about the transformational changes in gut microbes revealed in PCOS patients and the possible mechanisms and pathways by which the intestinal microbiome exerts influence on PCOS progression and phenotypes. In addition to the intestinal microbiome, evidence from animal studies suggests changes in the vaginal microbiome under PCOS conditions. The alteration of microbiome could affect oestrus cycle and PCOS phenotypes. Microbiome is closely associated with medicine and therapeutic approaches. Microbiome influences drug and therapy response and itself is a new source of therapy. Accurate modulation of the intestinal and vaginal microbiome is a potential therapy for PCOS patients. Future studies are required to elucidate the specific role of each particular genera of microbiota and the mechanism by which microbiome impacts the pathogenesis, progression and phenotypes of PCOS.

Sex Hormone-Binding Globulin (SHBG) as an Early Biomarker and Therapeutic Target in Polycystic Ovary Syndrome

Human sex hormone-binding globulin (SHBG) is a glycoprotein produced by the liver that binds sex steroids with high affinity and specificity. Clinical observations and reports in the literature have suggested a negative correlation between circulating SHBG levels and markers of non-alcoholic fatty liver disease (NAFLD) and insulin resistance. Decreased SHBG levels increase the bioavailability of androgens, which in turn leads to progression of ovarian pathology, anovulation and the phenotypic characteristics of polycystic ovarian syndrome (PCOS). This review will use a case report to illustrate the inter-relationships between SHBG, NAFLD and PCOS. In particular, we will review the evidence that low hepatic SHBG production may be a key step in the pathogenesis of PCOS. Furthermore, there is emerging evidence that serum SHBG levels may be useful as a diagnostic biomarker and therapeutic target for managing women with PCOS.

An Unusual Cause of Secondary Amenorrhea in an Adolescent: Expanding the Differential

Secondary amenorrhea is not uncommon in the adolescent female population. There are multiple etiologies to consider, and a comprehensive evaluation is often pursued. Sometimes, however, despite a thorough workup, the diagnosis remains unclear. Here, we report an unusual cause of secondary amenorrhea in a 15-year-old girl. Our patient presented with secondary amenorrhea after a 4-year history of regular menstrual cycles. Her evaluation was notable for very low FSH and low estradiol but normal LH; pregnancy, adrenal, thyroid, prolactin studies, and brain magnetic resonance imaging scan did not reveal a cause of her amenorrhea. Her transabdominal ultrasound showed an enlarged right ovary, initially suggestive of a hemorrhagic cyst. Inhibin A and B were measured because of the persistently low FSH; these were found to be very elevated, concerning for an inhibin-producing tumor. The patient had surgical removal of her right ovary; pathology revealed a juvenile granulosa-cell tumor. Postoperatively, the patient had normalization of serum inhibin A and B and resumption of normal menstrual cycles. This report illustrates that careful consideration of laboratory findings and other studies is essential for correctly identifying the underlying cause of secondary amenorrhea, particularly when the results are not consistent with common causes of this condition.

Reporting quality of polycystic ovary syndrome practice guidelines based on the RIGHT checklist

BACKGROUND

Polycystic ovary syndrome (PCOS) is a prevalent endocrine disorder involving hyperandrogenism, menstrual disorder, metabolic problems, infertility, obesity, and acne. The main aim of this study was to assess the reporting quality of clinical practice guidelines (CPGs) in the field of PCOS to provide a reporting specification for this study.

METHODS

We evaluated the reporting quality of clinical guidelines of PCOS using the Reporting Items for Practice Guidelines in HealThcare (RIGHT) checklist. Nine databases and 3 medical associations were searched. These included Medline, Embase, PubMed, National Institute for Health and Care Excellence (NICE), Guidelines International Network (GIN), National Guideline Clearinghouse (NGC), China National Knowledge Infrastructure, Wanfang and Chinese Science, and Technology Journal Database (VIP). Three medical associations included the European Society of Human Reproduction and Embryology, the American Society for Reproductive Medicine and the Agency for Healthcare Research and Quality. Two independent authors assessed the reporting quality of PCOS CPGs by the RIGHT checklist, and Spearman's correlation was used to assess inter-rater reliability.

RESULTS

Twelve PCOS CPGs were included. On average, 20.0 (57.1%) of the 35 items in the RIGHT checklist were reported. All items were fully reported by one of these CPGs. The number of reported items ranged from 10 (28.6%) to 35 (100%). Overall, 16.7%, 66.7%, and 16.7% of included guidelines were of high, medium, and low quality, respectively. The reporting proportions of the 7 domains (i.e., Basic information, Background, Evidence, Recommendations, Reviewand quality assurance, Funding and declaration and management of interests, and Other information) in the RIGHT checklist were 62.0%, 69.1%, 53.3%, 60.7%, 33.3%, 31.2%, and 69.4%, respectively.

CONCLUSIONS

The evaluation of these CPGs by the RIGHT checklist revealed that the reporting quality varied among guidelines. Low quality items were the processes of evidence decision and the declaration of funding in most included CPGs. Guideline developers should pay more attention to these items to disseminate and implement better guidelines in near future.

Current concepts of polycystic ovary syndrome pathogenesis

PURPOSE OF REVIEW

This review provides a model for understanding polycystic ovary syndrome (PCOS) pathophysiology and updates the evidence on which it is based. Then, it highlights complimentary molecular genetic and epigenetic advances in understanding PCOS cause.

RECENT FINDINGS

Important studies into PCOS cause built on the 2014 discovery of a novel regulatory protein variant that underlies the typical PCOS steroidogenic abnormalities: DENND1A.V2 (differentially expressed in normal and neoplastic development, isoform 1A, variant 2). Over 30 DENND1A gene variants have been found, the vast majority upstream of the coding sequence and potentially regulatory. These variants are individually uncommon but collectively plausibly cause 50% of PCOS. Anti-Müllerian hormone (AMH)/AMH receptor variants with decreased function possibly cause 6.7% of PCOS. DENNND1A was recently reported to belong to a signaling network that upregulates luteinizing hormone receptor expression and insulin mitogenic signaling. Prenatal androgen administration has proven to be a potent epigenetic regulator that causes transgenerational epigenomic changes in a mouse PCOS model with similarities to those in human PCOS and PCOS daughters.

SUMMARY

In addition to finding how gene variants contribute to PCOS pathogenesis, better understanding of androgen epigenetic mechanisms of action in diverse tissues can be expected to expand our understanding of PCOS pathogenesis.

Perspectives on the International Recommendations for the Diagnosis and Treatment of Polycystic Ovary Syndrome in Adolescence

Recommendations have been provided for the diagnosis and therapy of polycystic ovary syndrome in adolescence from 3 international expert conferences 2015-2018. Despite agreement about essentials, differences among details of these recommendations have engendered confusion. This commentary provides perspective about the agreements and disagreements among these recommendations and how these recommendations relate to other guidance. It concludes with practice suggestions that align with these recommendations.

Anogenital distance in children born of mothers with polycystic ovary syndrome: the Odense Child Cohort

STUDY QUESTION

Are higher testosterone levels during pregnancy in women with polycystic ovary syndrome (PCOS) associated with longer offspring anogenital distance (AGD)?

SUMMARY ANSWER

AGD was similar in 3-month-old children born of mothers with PCOS compared to controls.

WHAT IS KNOWN ALREADY

AGD is considered a marker of prenatal androgenization.

STUDY DESIGN, SIZE, DURATION

Maternal testosterone levels were measured by mass spectrometry at Gestational Week 28 in 1127 women. Maternal diagnosis of PCOS before pregnancy was defined according to Rotterdam criteria. Offspring measures included AGD from anus to posterior fourchette (AGDaf) and clitoris (AGDac) in girls and to scrotum (AGDas) and penis (AGDap) and penile width in boys and body composition (weight and BMI SD scores) at age 3 months.

PARTICIPANTS/MATERIALS, SETTING, METHODS

The study was part of the prospective study, Odense Child Cohort (OCC), and included mothers with PCOS (n = 139) and controls (n = 1422). The control population included women with regular menstrual cycles (<35 days) before conception and no signs of androgen excess (hirsutism and/or acne).

MAIN RESULTS AND THE ROLE OF CHANCE

AGD measures were comparable in offspring of women with PCOS compared to controls (all P > 0.2) despite significantly higher maternal levels of total testosterone (mean: 2.4 versus 2.0 nmol/l) and free testosterone (mean: 0.005 versus 0.004 nmol/l) in women with PCOS versus controls (both P < 0.001). In women with PCOS, maternal testosterone was an independent positive predictor of offspring AGDas and AGDap in boys. Maternal testosterone levels did not predict AGD in girls born of mothers with PCOS or in boys or girls born of women in the control group.

LIMITATIONS, REASONS FOR CAUTION

The diagnosis of PCOS was based on retrospective information and questionnaires during pregnancy. Women participating in OCC were more ethnically homogenous, leaner, more educated and less likely to smoke compared to the background population. Our study findings, therefore, need to be reproduced in prospective study cohorts with PCOS, in more obese study populations and in women of other ethnicities.

WIDER IMPLICATIONS OF THE FINDINGS

Our finding of the same AGD in girls born of mothers with PCOS compared to controls expands previous results of studies reporting longer AGD in adult women with PCOS. Our results suggest that longer AGD in adult women with PCOS could be the result of increased testosterone levels in puberty, perhaps in combination with weight gain.

STUDY FUNDING/COMPETING INTEREST(S)

Financial grants for the study were provided by the Danish Foundation for Scientific Innovation and Technology (09-067180), Ronald McDonald Children Foundation, Odense University Hospital, the Region of Southern Denmark, the Municipality of Odense, the Mental Health Service of the Region of Southern Denmark, The Danish Council for Strategic Research, Program Commission on Health, Food and Welfare (2101-08-0058), Odense Patient data Explorative Network, Novo Nordisk Foundation (grant no. NNF15OC00017734), the Danish Council for Independent Research and the Foundation for research collaboration between Rigshospitalet and Odense University Hospital and the Health Foundation (Helsefonden).

Polycystic ovarian syndrome in adolescents: From diagnostic criteria to therapeutic management

Polycystic ovarian syndrome is a common endocrinologic condition diagnosed in women of childbearing age. It is primarily associated with androgen excess and ovarian dysfunction, which contribute to menstrual irregularity, oligo-anovulation, infertility, hirsutism and acne. It is associated with several systemic conditions, including type 2 diabetes mellitus, cardiovascular disease, obesity and neuropsychological disorders. The exact pathophysiology and clinical features are highly variable and, thus, there is still controversy in defining the diagnostic criteria. In this review, we outline the main diagnostic criteria, discuss the mechanisms involved in the complex pathogenesis, and present the associated clinical manifestations and therapeutic management of the syndrome in adolescents.
