Polycystic Ovarian Morphology in Normocyclic Non-hyperandrogenic Adolescents

Ovarian Morphology in Girls Longitudinal Cohort Study: Pilot Evaluation of Ovarian Morphology as a Biomarker of Reproductive and Metabolic Features during the First Gynecological Year

OBJECTIVE

The objective was to establish whether aspects of ovarian morphology correlate with reproductive and metabolic features during the first postmenarcheal year using data from the Ovarian Morphology in Girls (OMG!) cohort study. The feasibility of transabdominal ultrasonography to assess ovarian features was also determined.

METHODS

Healthy adolescent females enrolled in a prospective cohort study. Study visits occurred at 6-10, 11-13, 17-19, and 23-25 months postmenarche and entailed a physical exam, transabdominal ultrasound, and fasting blood draw. Participants maintained menstrual diaries throughout the study. The present analysis reflects participants who completed the study visit at 6-10 months postmenarche. Associations between ovarian morphology or average cycle length with reproductive and metabolic features were assessed by Spearman correlations and linear regression.

RESULTS

Forty participants enrolled in the OMG!

STUDY

Thirty-one participants initiated study procedures at 6-10 months postmenarche, and data were available for analysis for 29 participants. Image quality was judged as partially visible or excellent in 90% of the left and 78% of the right ovaries assessed, with all images collected having sufficient image quality to provide measurements of at least 1 ovarian marker. The follicle number per ovary and ovarian volume were positively associated with anti-Müllerian hormone levels and negatively associated with fasting insulin. The average cycle length was only associated negatively with triglycerides.

CONCLUSION

Transabdominal ultrasonography in the early postmenarcheal period provides sufficient resolution to enable estimations of antral follicle count and ovarian size. Ovarian features in early gynecological life may correspond with measures of reproductive and metabolic function.

Prevalence of Polycystic Ovarian Syndrome in Young and Adolescent Transmasculine Patients Presenting for Gender-Affirming Care

STUDY OBJECTIVE

To determine the incidence of polycystic ovarian syndrome (PCOS) and hyperandrogenism among adolescent transmasculine patients presenting to a tertiary care referral center for gender-affirming care METHODS: This was a retrospective study of adolescent transmasculine patients presenting to Cleveland Clinic for gender-affirming hormone therapy. The diagnostic criteria were adolescent-specific as defined by the international evidence-based guideline for PCOS management and included oligomenorrhea and/or anovulation with clinical and/or biochemical hyperandrogenism after exclusion of other androgen excess disorders.

RESULTS

The described transgender population had a prevalence of PCOS of 23.8%. The transmasculine patients who met the criteria for PCOS had both higher levels of androgens and higher body mass indexes when compared with the patients without PCOS. Additionally, the patients with PCOS had higher rates of dyslipidemia.

CONCLUSION

The prevalence of PCOS among transmasculine patients may be higher compared with the general population. Transmasculine patients with PCOS should be counseled regarding the long-term health implications associated with PCOS and screened appropriately to minimize risks.

Probiotics and Polycystic Ovary Syndrome: A Perspective for Management in Adolescents with Obesity

Polycystic ovary syndrome (PCOS) affects a considerable percentage of females of reproductive age. PCOS is an obesity-related condition and its effects are greatly amplified by obesity. Even though the pathogenesis of PCOS remains complex and has not been fully elucidated, a link between obesity, PCOS, and dysbiosis has been described. The potential role of the gut microbiota in the development and progression of PCOS and its associated symptoms has also been reported. The aim of this narrative review is to present a non-systematic analysis of the available literature on the topic of probiotics and PCOS in adolescents with obesity in order to revise the beneficial effects of probiotics/symbiotic supplementation on hormonal and metabolic profiles and inflammatory conditions. The effectiveness of probiotics/synbiotics in PCOS has been supported. The literature suggests that probiotic/symbiotic supplementation may ameliorate hormonal profiles, inflammatory indicators, and lipid metabolism disturbances caused by PCOS. Studies also show improvements in weight, BMI, insulin, and HOMA-IR, including a potential role it plays in protecting fertility. Even though further studies are needed to confirm these findings, particularly in adolescent patients, probiotic supplementation may be considered a solution for managing PCOS in adolescents with obesity.

Evaluation of the Association of Endometrial Thickness, Insulin Resistance, and Menstrual Patterns in Adolescent Females with Polycystic Ovarian Syndrome

STUDY OBJECTIVE

To evaluate endometrial stripe (EMS) thickness and its association with menstrual pattern and insulin resistance in adolescent females with or at risk for polycystic ovarian syndrome (PCOS) METHODS: This was a retrospective case-control study of adolescent females ranging between 12 and 21 years old evaluated in the Adolescent Gynecology & Endocrinology Clinic (AGEC) at a tertiary children's hospital between 2017 and 2021. Transabdominal pelvic ultrasound (US) was obtained for evaluation of PCOS or acute pelvic pain. Unadjusted comparisons were performed between imaging measurements in the PCOS and control (girls without PCOS with acute pelvic pain) groups, as well as analysis of the PCOS group adjusted for age, body mass index, race, and biochemical values. This study was approved by the Institutional Review Board.

RESULTS

In our study, 54 subjects met the inclusion criteria for the PCOS group and 42 for the control group. EMS thickness was thinner in the PCOS group than in the control (0.55 ± 0.31 cm vs 0.70 ± 0.23 cm; P < .001). There was no difference in EMS thickness in the PCOS group when stratified by intermenstrual interval, insulin resistance, and other biochemical factors.

CONCLUSION

Our findings support recommendations by the 2018 International Guidelines to avoid use of US for the establishment of PCOS diagnosis in adolescents. These results highlight the unique pathophysiology of adolescent PCOS in contrast to PCOS in adult women. Further large-scale prospective studies are needed to understand the role of EMS thickness as a prognostic marker in adolescent PCOS.

PCOS in Adolescents-Ongoing Riddles in Diagnosis and Treatment

Polycystic ovary syndrome (PCOS) is one of the most common endocrine disorders in women of reproductive age. A diagnosis of PCOS is established when a patient exhibits two of three Rotterdam criteria: oligoovulation or anovulation, excess androgen activity, and polycystic ovarian morphology. The pathogenesis of PCOS, as it affects adolescents, is often discussed in terms of a "two-hit" theory. This refers to a stepwise process in which the first "hit" is an inborn congenitally programmed predisposition, while the second "hit" arises from a provocative factor such as insulin resistance. The dynamic physiological and anatomical changes which occur in puberty make for a challenging diagnosis in this group of patients. It is important to be mindful of the physiological particularities in adolescence which often mimic the symptoms of PCOS. In their first-year post-menarche, approximately 75% of menstruating adolescents report their cycle to last between 21-45 days. Recent studies have shown that regular menstrual cyclicity is only achieved within 2-3 years post-menarche. Anovulation, as a crucial diagnostic element for PCOS, features in about half of early-post-menarchal adolescents. Hirsutism and acne are the most common clinical manifestations of hyperandrogenism, and mild features are developed by most adolescents as a result of elevated androgen levels. Distinguishing between a pathological sign and normal features of maturation is often difficult. A polycystic ovarian morphology (PCOM) through ultrasound has been found in up to 40%, 35%, and 33.3% of patients when assessed at 2, 3, and 4 years, respectively, after menarche. PCOM in adolescence is not associated with future abnormalities in ovulatory rate or menstrual cycle duration. For this reason, international guidelines recommend against the use of pelvic ultrasound until 8 years post-menarche. The primary aim of management is focused mainly on improving hormonal and metabolic status, the prevention of future comorbid complications, and generally improving the overall quality of life in young women with PCOS. Considerable controversy surrounds the choice of optimal pharmacological treatment to address PCOS in adolescents. Reliable studies, which include this sub-section of the population, are very limited. There is a lack of robust and reliable trials in the literature addressing the use of combined oral contraceptives. Further work needs to be undertaken in order to provide safe and effective care to the adolescent population in this regard.

Criteria for Diagnosis of Polycystic Ovary Syndrome during Adolescence: Literature Review

Polycystic ovary syndrome (PCOS) is one of the most common endocrine conditions in women. PCOS may be more challenging to diagnose during adolescence due to an overlap with the physiological events of puberty, which are part of the diagnostic criteria in adult women. This review focuses on the evidence available in relation to PCOS diagnostic criteria for adolescents. Adolescent PCOS should be diagnosed using two main criteria irregular -menstrual cycles (relative to number of years post-menarche) and hyperandrogenism (clinical and/or biochemical); after excluding other conditions that mimic PCOS. Accurate definitions of the two main criteria will decrease challenges/controversies with the diagnosis and provide timely diagnosis during adolescence to establish early management. Despite the attempts to create accurate diagnostic criteria and definitions, this review highlights the limited research in this area, especially in the follow up of adolescents presenting with one diagnostic feature that are called “at risk of PCOS”. Studies in adolescents continue to use the Rotterdam diagnostic criteria that uses pelvic ultrasound. This is inappropriate, because previous and emerging data that show many healthy adolescents have polycystic ovarian morphology in the early years post-menarche. In the future, anti-Müllerian hormone levels might help support PCOS diagnosis if adolescents meet two main criteria.

Evaluation of Endocrine and Metabolic Changes in Polycystic Ovary Syndrome by Ultrasonic Imaging Features under an Intelligent Algorithm

To explore the application of intelligent algorithm-based ultrasound in the evaluation of polycystic ovary syndrome (PCOS) and the endocrine and metabolic changes of PCOS, 44 patients diagnosed with PCOS were recruited and rolled into three groups regarding detection methods. Backpropagation algorithm-based ultrasonic detection was adopted for the patients in the experimental group. The patients in the control group were tested by conventional ultrasound. In addition, 18 healthy volunteers were selected as the normal group. The results showed that the images processed by the backpropagation algorithm were substantially better than the traditional ultrasound images (P < 0.05), and the image display was clearer. S, A, and S/A ratios measured by two different detection methods were 7.8 mm², 3.5 mm², and 0.449 in the experimental group, respectively, which were significantly different from 6.3 mm², 2.6 mm², and 0.413 in the control group (P < 0.05). The PI and RI values of the interstitial ovarian artery in the experimental group were lower than those in the control group, and the systolic peak velocity (PSV) and end diastolic velocity (EDV) values were higher than those in the control group (P < 0.05). Compared with the control group, the ovarian volume, interstitial vascularization-flow index (VFI), and flow index (FI) in the experimental group were substantially increased, and the total number of detected follicles was more (P < 0.05). The level of follicle-stimulating hormone (FSH) in PCOS patients was substantially lower than that in normal controls (P < 0.05). The LH, E₂, P, and T of PCOS patients were substantially higher than those of normal controls (P < 0.05). Ultrasound on account of the backpropagation algorithm can directly display the three-dimensional structure of the ovary and follicle and accurately measure the ovarian volume and follicle number. Endocrine and metabolic indicators can provide objective information for the clinical diagnosis of PCOS and can be used as a way of clinical evaluation of PCOS.

Polycystic Ovary Syndrome in Adolescence

Polycystic ovary syndrome (PCOS) is a common, complex, and chronic condition that presents many diagnostic and management challenges for managing clinicians. PCOS diagnosis in adolescents presents a particular challenge for treating clinicians due to the overlap of diagnostic features with normal physiological changes during adolescence. Adolescent diagnostic criteria include well-defined menstrual irregularity according to time postmenarche and hyperandrogenism, but does not require the use of pelvic ultrasound. Adolescents with only one criterion should be considered at risk of PCOS and be followed up around transition to adult care. While PCOS was traditionally considered to be a reproductive disorder, PCOS is now recognized to have major metabolic and cardiovascular health consequences and psychological sequelae that can be present from adolescence. Management of PCOS includes healthy lifestyle, metformin, combined oral contraceptive pill, and/or antiandrogens according to symptoms of concern even in adolescents at risk of PCOS.

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

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