Prevalence and correlates of diagnosed and probable polycystic ovary syndrome (PCOS) in a cohort of parous women.

OBJECTIVES: To assess correlates of diagnosed and probable polycystic ovary syndrome (PCOS) among parous women. METHODS: This study includes 557 women recruited from multi-specialty clinics in eastern Massachusetts. We categorized women as "diagnosed PCOS" based on medical records and self-reported clinician-diagnoses. Next, we constructed a category of "probable PCOS" for women without a diagnosis but with ≥2 of the following: ovulatory dysfunction (cycle length<21 or ≥35 days), hyperandrogenism (free testosterone>75th percentile), or elevated anti-Müllerian hormone (>75th percentile). We classified the remaining as "no PCOS," and compared characteristics across groups. RESULTS: 9.7% had diagnosed and 9.2% had probable PCOS. The frequency of irregular cycles was similar for diagnosed and probable PCOS. Free testosterone and AMH were higher for probable than diagnosed PCOS. Frequency of irregular cycles and both hormones were higher for the two PCOS groups vs. the no PCOS group. Obesity prevalence for diagnosed PCOS was twice that of probable PCOS (43.9% vs. 19.6%), yet the two groups had similar HbA1c and adiponectin. CONCLUSIONS: Women with probable PCOS are leaner but have comparable glycemic traits to those with a formal diagnosis, highlighting the importance of assessing biochemical profiles among women with irregular cycles, even in the absence of overweight/obesity.

Impact of the difference in diagnostic criteria for adolescent polycystic ovary syndrome excluding polycystic ovarian morphology.

AIM: Exclusion of polycystic ovarian morphology (PCOM) from the diagnostic criteria for adolescent polycystic ovary syndrome (PCOS) has been proposed. We analyzed the profiles of adolescent women with suspected PCOS based on the Japan Society of Obstetrics and Gynecology (JSOG) diagnostic and Rotterdam criteria, excluding those with PCOM. METHODS: Thirteen- to twenty-one-year-old women with suspected or confirmed diagnosis of PCOS according to the JSOG and Rotterdam criteria were included in this study. Patient characteristics such as hormone levels and body mass index (BMI) were compared between the groups. Correlations between BMI and testosterone, and BMI and time to diagnosis were also analyzed. RESULTS: Twenty-nine patients were diagnosed with adolescent PCOS according to the JSOG criteria, and 11 patients according to the Rotterdam criteria after excluding the patients fulfilling the PCOM criteria. Serum testosterone levels were significantly higher in adolescents diagnosed with PCOS using the Rotterdam criteria than in those diagnosed using the JSOG criteria (p < 0.001). The obese group had significantly higher testosterone levels and a longer time from menarche to PCOS diagnosis. A positive correlation was observed between BMI and testosterone levels (r = 0.318, p = 0.014). CONCLUSION: Although adolescents with PCOS diagnosed using the Rotterdam criteria exhibited higher testosterone levels, which is a typical characteristic of this condition, the JSOG criteria may be useful for the early diagnosis of adolescent PCOS, including suspected cases. The differences between the two criteria may reflect the natural history of PCOS and its different reproductive and metabolic phenotypes.

Global prevalence of polycystic ovary syndrome in women worldwide: a comprehensive systematic review and meta-analysis.

BACKGROUND: Polycystic ovary syndrome (PCOS) is the most common metabolic disorder among women of reproductive age. Many factors are involved in the development of PCOS, among which genetic predisposition is probably the main contributor that is also influenced by lifestyle and environmental factors. This study aims to determine the prevalence of PCOS in different continents based on Rotterdam, AES and NIH diagnostic criteria. METHODS: We conducted a systematic review and meta-analysis to evaluate the prevalence of polycystic ovary syndrome in women according to (Preferred Reporting Items for Systematic Review and Meta-Analysis) PRISMA guidelines. PubMed, Scopus, Science Direct, Web of Science and Google Scholar databases were comprehensively searched until February 2021 for relevant articles. Heterogeneity between the studies was assessed using the I2 index. Begg and Mazumdar's test was used to evaluate publication bias. RESULTS: A total of 35 studies with 12,365,646 subjects were retrieved. The mean age ranged from 10-45 years. Global prevalence of PCOS was 9.2% (95% CI: 6.8-12.5%) based on meta-analysis, our results showed that the global prevalence of PCOS was 5.5% (95% CI: 3.9-7.7%) based on NIH criteria, 11.5 (95% CI: 6.6-19.4) based on Rotterdam criteria, and 7.1% (95% CI: 2.3-20.2%) based on AES criteria. According to self-report subgroup analysis, the prevalence of PCOS was found to be 11% (95% CI: 5.2-21.8%). CONCLUSION: Based on the results of the present study, the prevalence of PCOS in the world was 9.2% (95% CI: 6.8-12.5%). According to the results of the present study and the high prevalence of PCOS, especially in the Africa continent, it is necessary for health systems to implement measures to timely prevent and treat this syndrome.

PCOS phenotype focus: phenotype D under the magnifying glass.

Polycystic ovary syndrome (PCOS) is defined as the combination of polycystic morphology, hyperandrogenism, and ovulatory disruption; this heterogeneity presents a conundrum for the medical community. The Rotterdam criteria have governed the diagnosis of PCOS, separating the patient cohort into four distinct phenotypes. It has been suggested that the lone normoandrogenic phenotype, so-called phenotype D, should not be classified as a PCOS subtype, with phenotypes A, B, and C displaying a hyperandrogenic biochemical and clinical profile thought to be characteristic of PCOS. To understand how to treat phenotype D patients, this review shines a spotlight on the phenotype, gathering various reports of how phenotype D is differentiated from the other PCOS phenotypes.

Serum Expression of miR-23a-3p and miR-424-5p Indicate Specific Polycystic Ovary Syndrome Phenotypes: A Pilot Study.

MicroRNAs (miRNAs) are single-stranded, non-coding RNAs that regulate mRNA expression on a post-transcriptional level. Observational studies suggest an association of serum miRNAs and polycystic ovary syndrome (PCOS), a common heterogeneous endocrinopathy characterized by hyperandrogenism (HA), oligo- or amenorrhea (OM) and polycystic ovaries. It is not known whether these miRNA profiles also differ between PCOS phenotypes. In this pilot study, we compared serum expression profiles between the four PCOS phenotypes (A-D) and analyzed them both in PCOS (all phenotypes) and in phenotypes with HA by quantitative-real-time PCR (qRT-PCR). The serum expression of miR-23a-3p was upregulated in phenotype B (n = 10) and discriminated it from phenotypes A (n = 11), C (n = 11) and D (n = 11, AUC = 0.837; 95%CI, 0.706-0.968; p = 0.006). The expression of miR-424-5p was downregulated in phenotype C (n = 11) and discriminated it from phenotypes A, B and D (AUC = 0.801; 95%CI, 0.591-1.000; p = 0.007). MiR-93-5p expression was downregulated in women with PCOS (all phenotypes, n = 42) compared to controls (n = 8; p = 0.042). Phenotypes with HA (A, B, C; n = 32) did not show differences in the analyzed expression pattern. Our data provide new insights into phenotype-specific miRNA alterations in the serum of women with PCOS. Understanding the differential hormonal and miRNA profiles across PCOS phenotypes is important to improve the pathophysiological understanding of PCOS heterogeneity.

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.

Ovarian Endocrine Status and ART 0utcomes in Women within PCOS Based on Different Testosterone Levels.

Background: It is estimated that in women at reproductive age, the risk of polycystic ovary syndrome (PCOS) is about 5-21%. In PCOS cases with ovulation dysfunction, assisted reproductive techniques (ART) are useful for infertility treatment. Objective: This study aimed to evaluate the ART outcome in infertile PCOS women based on different testosterone levels. Finally, the relationships between testosterone in different levels and reproductive parameters including endocrine status, the response of ovaries, and pregnancy outcomes were assessed. Methods: In this retrospective study, 352 infertile PCOS women were examined. The women were categorised into five groups according to their testosterone levels: A = T < 0.4, B = 0.4 < T > 0.6, C = 0.6 < T > 0.8, D = 0.8 < T > 1.0 and E = T > 1.0 ng/dL. All study cases were in similar hyper-stimulation protocol and finally, hormonal profile and ART outcomes were compared between testosterone levels. P value ≤ 0.05 was statistically significant. Results: In testosterone levels >1.0, the levels of anti-mullerian hormone (AMH) and luteinising hormone (LH) were higher than in other testosterone level groups. AMH (P = 0.05) and LH (P = 0.001) levels showed significant differences. No correlation was present between testosterone levels and ART outcomes, including stimulation duration, endometrial thickness, oocyte numbers, numbers of matured oocytes, number of obtained embryos, fertilisation rate, implantation rate clinical pregnancy and abortion rate. Conclusions: Serum testosterone levels did not show any correlation with pregnancy outcomes in ART cycles of PCOS. However, basal testosterone levels are a good predictor for ovarian reserve and ovarian response. Consequently, we suggest that some prospective studies must be designed to approve the role of testosterone in the prediction of the outcome of pregnancy in ART cycles.

Homoeopathy a system of holistic healing as an alternative treatment for PCOS: a review

Polycystic ovarian syndrome (PCOS) is a complex hormonal and metabolic disorder characterized by oligomenorrhea or amenorrhea, hyperandrogenism and infertility. Global prevalence of PCOS is estimated to be between 06% and 26%. Homoeopathy, being a system of holistic healing can be accepted as one of the alternative treatments for PCOS. Aim & Objective: The aim of the study is to review clinical data, where the intervention was aimed to treat PCOS through Homoeopathy. The objective of the study is to identify the therapeutic approach, assessment criteria, treatment outcomes through an alternative therapy i.e., Homoeopathy in cases of PCOS. Methods: A systematic literature search was conducted in the month of June2021 following International/National search databases for all clinical studies published in the period from 2000 to 2021. This search was aimed to target the entire literature of randomized trials or controlled trials, observational studies case studies/reports on PCOS in homoeopathy. Result:28 articles related to Homoeopathy on PCOS were identified. Out of these 28studies, 22 studies (01 RCT, 02 NRCT,06 observational studies,04 case series and 09 case reports) were included in this review. All studies were published in peer reviewed journals.Conclusions:To establish the evidence-based efficacy of the homoeopathic treatment in cases of RCT more pragmatic studies need to be planned in the future based on proper diagnostic criteria.

Is there any association between vitamin D levels and polycystic ovary syndrome (PCOS) phenotypes?

ABSTRACT Objective The aim of this study was to assess the serum vitamin D level in a retrospective study in women with polycystic ovary syndrome (PCOS), according to the different phenotypes of the disease. Subjects and methods In this retrospective study, the records of 351 infertile women who were diagnosed with PCOS were examined, and 200 of them were enrolled in the study randomly in 4 PCOS phenotypes. Fifty normal ovulatory women with the history of male factor were selected as the control group. Parameters, including age, infertility duration, body mass index (BMI), hormone profile, as well as the serum vitamin D level were compared among the 4 phenotypes, with the P-value ≤ 0.05 considered statistically significant. Results The findings showed a higher serum vitamin D level in the control group than in PCOS patients, which was statistically significant (P < 0.001). In addition, there was no significant difference in the serum vitamin D level among the four phenotypes of PCOS. Conclusions No significant difference was found in the serum vitamin D level of the different phenotypes of PCOS. Further studies with larger sample sizes are recommended to be done to establish the role of the serum vitamin D level in PCOS patients.
