RESUMO

OBJECTIVE: The present study aimed to clarify the conflicting association of premenopausal hyperandrogenaemia (HA) with the development of hypertension and CVDs in women. DESIGN: A population-based cohort study including 5889 women. METHODS: The association of serum testosterone (T), sex hormone-binding globulin (SHBG), and free androgen index (FAI) at age 31 with blood pressure (BP) and hypertension (BP ≥140/90 mmHg and/or use of antihypertensive medication) at ages 31 and 46 and with CVDs (angina pectoris [AP] and/or acute myocardial infarction [AMI] n=74, transitory cerebral ischemia [TIA] and/or stroke n=150) and combined CVD events (AP, AMI, stroke, heart failure, or CVD mortality n=160) by age 53 was investigated. RESULTS: T and FAI were positively associated with systolic and diastolic BP at ages 31 and 46 in the multivariable model. Compared to their lowest quartile, the highest quartiles of T and FAI were positively associated with hypertension at age 31 in the multivariable model. During the 22-year follow-up, FAI was positively associated with increased risk of AP/AMI (hazard ratio [HR]:2.02, 95%CI:1.06-3.85) and overall CVD events or mortality (HR:1.54, 95%CI:1.02-2.33) in the unadjusted models. However, the significance disappeared after adjusting for BMI. CONCLUSIONS: Women with HA at premenopausal age had an elevated risk of hypertension, and together with BMI, increased risk of CVD events and CVD mortality during the 22-year follow-up. However, because of several study limitations regarding ethnicity and BMI characteristics, a longer follow-up of this cohort and future studies in ethnically diverse populations are needed to verify the results.

RESUMO

Pericytes are versatile cells integral to the blood vessel walls of the microcirculation, where they exhibit specific stem cell traits. They are essential in modulating blood flow, ensuring vascular permeability, and maintaining homeostasis and are involved in the tissue repair process. The human endometrium is a unique and complex tissue that serves as a natural scar-free healing model with its cyclical repair and regeneration process every month. The regulation of pericytes has gained increasing attention due to their involvement in various physiological and pathological processes. However, endometrial pericytes are less well studied compared to the pericytes in other organs. This review aims to provide a comprehensive overview of endometrial pericytes, with a focus on elucidating their physiological function and potential implications in uterine disorders.

RESUMO

Polycystic ovary syndrome (PCOS) is a highly prevalent disorder in women that is commonly accompanied by metabolic syndrome. Activation of the hypoxia-inducible factor (HIF) pathway is known to alleviate metabolic defects. Hence, this study utilized a preclinical PCOS mouse model to investigate the effects of chemically induced HIF activation on the metabolic traits of PCOS. Prepubertal letrozole treatment was used to generate a PCOS mouse model in the C57Bl6/J strain, and PCOS mice were orally treated with vehicle or roxadustat for six weeks from age 12 weeks onwards to induce HIF activation. Although the PCOS mice showed impaired glucose tolerance, increased insulin resistance, elevated blood lipids, and reduced muscle glycogen content, there was no difference in histological evaluations of white adipose tissue (WAT) or liver or in organ weights. Roxadustat treatment resulted in significant improvement in glucose tolerance (27 % reduction in area under the curve (AUC) values, p < 0.0001), fasting glucose levels (4.59 ± 0.83 mmol/l vs 3.05 ± 0.62 mmol/l, p < 0.0001) and insulin resistance (46 % reduction in homeostasis model assessment-insulin resistance (HOMA-IR) values, 6.76 ± 3.72 vs 3.64 ± 2.44, p = 0.019) compared to vehicle-treated mice without altering the body weight. Gene expression analyses with real-time quantitative polymerase chain reaction (RT-qPCR) and RNA sequencing revealed significant differences in gene expression in the tissues of PCOS mice compared to control mice, whereas the transcriptomic effects of roxadustat were mainly transient. However, immunohistochemistry revealed increased uncoupling protein 1 (UCP1) expression in WAT, which may indicate WAT browning related to HIF pathway activation.

RESUMO

INTRODUCTION: The 2024 Australian evidence-based guideline for unexplained infertility provides clinicians with evidence-based recommendations for the optimal diagnostic workup for infertile couples to establish the diagnosis of unexplained infertility and optimal therapeutic approach to treat couples diagnosed with unexplained infertility in the Australian health care setting. The guideline recommendations were adapted for the Australian context from the rigorous, comprehensive European Society of Human Reproduction and Embryology (ESHRE) 2023 Evidence-based guideline: unexplained infertility, using the ADAPTE process and have been approved by the Australian National Health and Medical Research Council. MAIN RECOMMENDATIONS: The guideline includes 40 evidence-based recommendations, 21 practice points and three research recommendations addressing: definition - defining infertility and frequency of intercourse, infertility and age, female and male factor infertility; diagnosis - ovulation, ovarian reserve, tubal factor, uterine factor, laparoscopy, cervical/vaginal factor, male factor, additional testing for systemic conditions; and treatment - expectant management, active treatment, mechanical-surgical procedures, alternative therapeutic approaches, quality of life. CHANGES IN ASSESSMENT AND MANAGEMENT RESULTING FROM THE GUIDELINE: This guideline refines the definition of unexplained infertility and addresses basic diagnostic procedures for infertility assessment not considered in previous guidelines on unexplained infertility. For therapeutic approaches, consideration of evidence quality, efficacy, safety and, in the Australian setting, feasibility, acceptability, cost, implementation and ultimately recommendation strength were integrated across multidisciplinary expertise and consumer perspectives in adapting recommendations to the Australian context by using the Grading of Recommendations, Assessment, Development and Evaluation (GRADE) framework, which had not been used in past guidelines on unexplained infertility to formulate recommendations. The Australian process also included an established data integrity check to ensure evidence could be trusted to guide practice. Practice points were added and expanded to consider the Australian setting. No evidence-based recommendations were underpinned by high quality evidence, with most having low or very low quality evidence. In this context, research recommendations were made including those for the Australian context. The full guideline and technical report are publicly available online and can be accessed at https://www.monash.edu/medicine/mchri/infertility and are supported by extensive translation resources, including the free patient ASKFertility mobile application (https://www.askfertility.org/).

RESUMO

OBJECTIVE: To investigate eating behavior domains -emotional, uncontrolled, and cognitive restraint eating- in women with polycystic ovary syndrome (PCOS) with different PCOS phenotypes and women without PCOS at midlife. DESIGN: A prospective cohort study. Eating behavior domains were assessed at age 46. Predictors of eating behaviors were evaluated using variables collected at ages 31 and 46. SUBJECTS: Women identified as having PCOS (n=251) at age 31 using the updated Rotterdam criteria were compared to women without any PCOS criteria (n=935). The PCOS population comprised women with the classic A+B-phenotype (hyperandrogenism and oligomenorrhea, with or without elevated anti-Müllerian hormone, n=60), C-phenotype (hyperandrogenism and elevated anti-Müllerian hormone, n=84), and D-phenotype (oligomenorrhea and elevated anti-Müllerian hormone, n=86). EXPOSURE: The main explanatory variables for the eating behavior domains were PCOS, body mass index, a history of weight loss attempts, a perception of being overweight, and psychological distress. MAIN OUTCOME MEASURES: Revised Three-Factor Eating Questionnaire-18 scores for eating behavior domains. RESULTS: Compared to women without PCOS, women with PCOS exhibited higher scores for emotional (33.1±27.8 vs. 39.0±29.9, p=0.005) and uncontrolled eating (26.7±18.2 vs. 30.7±19.4, p=0.003) but no difference in cognitive restraint (46.6±18.6 vs. 45.9±18.5, p=0.563) at age 46. Emotional and uncontrolled eating scores were higher in the A+B-phenotype compared to women without PCOS, while uncontrolled eating scores in the C-phenotype were higher than in women without PCOS and the D-phenotype. At age 46, the perception of overweight was an independent predictor of emotional eating among women with PCOS (B=11.96 [95% confidence interval [CI]: 2.81-20.29], p=0.008), while a history of weight loss attempts was a predictor of uncontrolled eating (B=6.06 [95% CI: 1.05-10.83], p=0.015). Among women with PCOS, higher psychological distress at age 31 was a significant risk factor for scoring in the highest quartile of emotional (adjusted odds ratio [aOR]: 2.85 [95% CI: 1.19-6.85], p=0.019) and uncontrolled eating (aOR: 4.37 [95% CI: 1.77-10.80], p=0.001) at age 46. CONCLUSION: Women with PCOS at midlife showed a high tendency for unfavorable eating behaviors. Our findings emphasize the need for sensitivity in weight management counseling and addressing psychological distress to prevent unfavorable eating in this population.

RESUMO

Stanniocalcin (STC) 1 and 2 serve as antihyperglycemic polypeptide hormones with critical roles in regulating calcium and phosphate homeostasis. They additionally function as paracrine and/or autocrine factors involved in numerous physiological processes, including female reproduction. STC1 and STC2 contribute to the pathophysiology of several diseases, including female infertility- and pregnancy-associated conditions, and even tumorigenesis of reproductive organs. This comprehensive review highlights the dynamic expression patterns and potential dysregulation of STC1 and STC2, restricted to female fertility, and infertility- and pregnancy-associated diseases and conditions, such as endometriosis, polycystic ovary syndrome (PCOS), abnormal uterine bleeding, uterine polyps, and pregnancy complications, like impaired decidualization, preeclampsia, and preterm labor. Furthermore, the review elucidates the role of dysregulated STC in the progression of cancers of the reproductive system, including endometrial, cervical, and ovarian cancers. Additionally, the review evaluates the expression patterns and prognostic significance of STC in gynecological cancers by utilizing existing public datasets from The Cancer Genome Atlas to help decipher the multifaceted roles of these pleiotropic hormones in disease progression. Understanding the intricate mechanisms by which STC proteins influence all these reviewed conditions could lead to the development of targeted diagnostic and therapeutic strategies in the context of female reproductive health and oncology.

RESUMO

The Women's Health Study (WENDY) was conducted to improve insights into women's health and health burden. It provides a unique, comprehensive data source that can be broadly utilised to understand gynaecological symptoms, diseases, and their relation to metabolic and overall health more deeply in a population-based setting. The study was conducted in Finland from May 2020 to October 2022. It included 1,918 women (33-37 years old) who were born in Northern Finland between July 1985 and December 1987. Data collection comprised one three-to-four-hour study visit that included clinical measurements, biological samples, ultrasound examinations and an extensive questionnaire on gynaecological and reproductive history, physical and mental health, quality of life, lifestyles, current life situations, health awareness and opinions. The study also included a menstrual cycle follow-up and cognitive testing up to three months via a mobile application. Given that all participants' data can be linked to all Finnish national registers, and the NFBC participants' data can be linked to the birth cohort data set collected from gestational week 24 onwards, WENDY study forms one of the largest datasets worldwide to investigate gynecological and metabolic health burden in women.

RESUMO

It is not controversial to state that parental age is increasing in several countries. But how to deal with this increase might be. Some Nordic countries have set an upper age limit for females seeking assisted reproduction in their national legislation, but none have done so for males. There are also recommendations in place that restrict access to publicly funded assisted reproduction for both females and males of advanced age in some Nordic countries. As recent data now show somatic and psychiatric health risks related to advanced paternal age, we ask if the time has come for countries to set an upper age limit for males seeking assisted reproduction like there already is for females, and summarize some of the risks and rewards involved in treating couples with advanced age in fertility clinics.

RESUMO

Phthalates are endocrine disrupting chemicals (EDCs) found in common consumer products such as soft plastics and cosmetics. Although the knowledge regarding the adverse effects of phthalates on female fertility are accumulating, information on the hormone sensitive endometrium is still scarce. Here, we studied the effects of phthalates on endometrial cell proliferation and gene expression. Human endometrial primary epithelial and stromal cells were isolated from healthy fertile-aged women (n=3), and were compared to endometrial cell lines T-HESC and Ishikawa. Three different epidemiologically relevant phthalate mixtures were used, defined by urine samples in the Midlife Women Health Study (MWHS) cohort. Mono (2-ethyl-5-hydroxyhexyl) phthalate (MEHHP) was used as a single phthalate control. Cells were harvested for proliferation testing and transcriptomic analyses after 24 h exposure. Even though all cell models responded differently to the phthalate exposures, many overlapping differentially expressed genes (DEGs, FDR<0.1), related to cell adhesion, cytoskeleton and mitochondria were found in all cell types. The qPCR analysis confirmed that MEHHP significantly affected cell adhesion gene vinculin (VCL) and NADH:ubiquinone oxidoreductase subunit B7 (NDUFB7), important for oxidative phosphorylation. Benchmark dose modelling showed that MEHHP had significant concentration-dependent effects on cytoskeleton gene actin-beta (ACTB). In conclusion, short 24 h phthalate exposures significantly altered gene expression cell-specifically in human endometrial cells, with six shared DEGs. The mixture effects were similar to those of MEHHP, suggesting MEHHP could be the main driver in the mixture. Impact of phthalate exposures on endometrial functions including receptivity should be addressed.

RESUMO

The beneficial effects of physical activity (PA) on gut microbiome have been reported, nevertheless the findings are inconsistent, with the main limitation of subjective methods for assessing PA. It is well accepted that using an objective assessment of PA reduces the measurement error and also allows objective assessment of sedentary behavior (SB). We aimed to study the associations between accelerometer-assessed behaviors (i.e., SB, light-intensity physical activity [LPA] and moderate-to-vigorous physical activity [MVPA]) with the gut microbiome using compositional data analysis, a novel approach that enables to study these behaviors accounting for their inter-dependency. This cross-sectional study included 289 women from the Northern Finland Birth Cohort 1966. Physical activity was measured during 14 days by wrist-worn accelerometers. Analyses based on the combined effect of MVPA and SB, and compositional data analyses in association with the gut microbiome data were performed. The microbial alpha- and beta-diversity were not significantly different between the MVPA-SB groups, and no differentially abundant microorganisms were detected. Compositional data analysis did not show any significant associations between any movement behavior (relative to the others) on microbial alpha-diversity. Butyrate-producing bacteria such as Agathobacter and Lachnospiraceae CAG56 were significantly more abundant when reallocating time from LPA or SB to MVPA (γ = 0.609 and 0.113, both p-values = 0.007). While PA and SB were not associated with microbial diversity, we found associations of these behaviors with specific gut bacteria, suggesting that PA of at least moderate intensity (i.e., MVPA) could increase the abundance of short-chain fatty acid-producing microbes.

RESUMO

Screening for polycystic ovary syndrome (PCOS) in antenatal care is inadequate, largely owing to the lack of clarity around whether PCOS is an independent risk factor for pregnancy complications. This systematic review and meta-analysis include 104 studies and 106,690 pregnancies in women with and without PCOS from inception until 13th July 2022. We report that women with PCOS are younger and have higher body mass index (BMI) around conception and have greater gestational weight gain. The odds of miscarriage, gestational diabetes mellitus, gestational hypertension, pre-eclampsia and cesarean section are higher in women with PCOS. The increased odds of adverse outcomes in PCOS remain significant when age and BMI are matched and when analyses are restricted to high-quality studies. This work informed the recommendations from the 2023 international evidence-based guideline for the assessment and management of polycystic ovary syndrome, emphasizing that PCOS status should be captured in all women who are planning to, or have recently become pregnant to facilitate prevention of adverse outcomes and improve pregnancy outcomes.

RESUMO

It is unclear whether polycystic ovary syndrome (PCOS) is an independent risk factor for adverse birth outcomes in the offspring of affected women. Here, we investigate the association of PCOS with birth outcomes in the offspring of women with PCOS overall and by potential confounders. This systematic review and meta-analysis included 73 studies and 92,881 offspring of women with and without PCOS from inception until 13th July 2022. We report that mothers with PCOS are younger and have higher body mass index (BMI) around conception and have greater gestational weight gain. The odds of preterm birth, fetal growth restriction and low birth weight are higher and mean birthweight is lower in PCOS of which a lower mean birthweight and a higher small for gestational age are probably independent of BMI. This work informed the recommendations from the 2023 international evidence-based guideline for the assessment and management of polycystic ovary syndrome, emphasizing that PCOS status should be captured at pregnancy to identify risk and improve birth outcomes in the offspring.

RESUMO

PURPOSE: To describe the effects of estetrol (E4) 15 mg/drospirenone (DRSP) 3 mg on physical and emotional premenstrual and menstrual symptoms. MATERIALS AND METHODS: We used Menstrual Distress Questionnaire (MDQ) data from a phase-3 trial (NCT02817828) in Europe and Russia with participants (18 - 50 years) using E4/DRSP for up to 13 cycles. We assessed mean changes in MDQ-t-scores from baseline to end of treatment in premenstrual (4 days before most recent flow) and menstrual (most recent flow) scores for 4 MDQ domains in starters and switchers (use of hormonal contraception in prior 3 months) and performed a shift analysis on individual symptoms within each domain. RESULTS: Of 1,553 treated participants, 1,398(90.0%), including 531(38%) starters, completed both MDQs. Starters reported improvements for premenstrual Pain (-1.4), Water Retention (-3.3) and Negative Affect (-2.5); and for menstrual Pain (-3.5), Water Retention (-3.4), and Negative Affect (-2.7) (all p < 0.01). For switchers, no changes were significant except an increase in premenstrual (+1.0, p = 0.02) and menstrual (+1.5, p = 0.003) Water Retention. We observed a change in symptom intensity in >40% of participants for Cramps, Backache and Fatigue (domain Pain), Painful or Tender Breast and Swelling (domain Water Retention) and Mood Swings and Irritability (domain Negative Affect). CONCLUSION: E4/DRSP starters experienced significant improvements in the domains Pain, Water Retention and Negative Affect particularly benefiting those with more severe baseline symptoms. Switchers showed minimal changes.


A phase 3 study in Europe and Russia showed that Estetrol/Drospirenone, a new combined oral contraceptive, significantly improved the MDQ scores for domains Pain, Water Retention and Negative Affect in women starting COC use, while switchers showed minimal changes.

RESUMO

STUDY QUESTION: What is the prospective risk of Type 2 diabetes (T2D) in Nordic women with polycystic ovary syndrome (PCOS) compared to controls? SUMMARY ANSWER: A diagnosis of PCOS and BMI ≥30 kg/m2 is a high-risk phenotype for a prospective risk of T2D diagnosis across Nordic countries. WHAT IS KNOWN ALREADY: The risk of T2D in women with PCOS is increased. The risk of T2D is related to BMI and the magnitude of risk in normal weight women with PCOS has been discussed. However, prospective data regarding risk of T2D in population-based cohorts of women with PCOS are limited. STUDY DESIGN, SIZE, DURATION: This national register-based study included women with PCOS and age-matched controls. The main study outcome was T2D diagnosis occurring after PCOS diagnosis. T2D was defined according to ICD-10 diagnosis codes and/or filled medicine prescriptions of anti-diabetic medication excluding metformin. PARTICIPANTS/MATERIALS, SETTING, METHODS: The study cohort included women originating from Denmark (PCOS Denmark, N = 27 016; controls, N = 133 994), Finland (PCOS Finland, N = 20 467; controls, N = 58 051), and Sweden (PCOS Sweden, N = 52 409; controls, N = 254 010). The median age at cohort entry was 28 years in PCOS Denmark, Finland, and Sweden with a median follow-up time (interquartile range) in women with PCOS of 8.5 (4.0-14.8), 9.8 (5.1-15.1), and 6.0 (2.0-10.0) years, respectively. Cox regression analyses were adjusted for BMI and length of education. MAIN RESULTS AND THE ROLE OF CHANCE: The crude hazard ratio (HR, 95% CI) for T2D diagnosis in women with PCOS was 4.28 (3.98-4.60) in Denmark, 3.40 (3.11-3.74) in Finland, and 5.68 (5.20-6.21) in Sweden. In adjusted regression analyses, BMI ≥30 vs <25 kg/m2 was associated with a 7.6- to 11.3-fold risk of T2D. In a combined meta-analysis (PCOS, N = 99 892; controls, N = 446 055), the crude HR for T2D in PCOS was 4.64 (3.40-5.87) and, after adjustment for BMI and education level, the HR was 2.92 (2.32-3.51). LIMITATIONS, REASONS FOR CAUTION: Inclusion of more severe cases of PCOS in the present study design could have lead to an overestimation of risk estimates in our exposed population. However, some women in the control group would have undiagnosed PCOS, which would lead to an underestimation of T2D risk in women with PCOS. BMI data were not available for all participants. The present study should be repeated in study cohorts with higher background risks of T2D, particularly in populations of other ethnicities. WIDER IMPLICATIONS OF THE FINDINGS: The prospective risk for diagnosis of T2D is increased in women with PCOS, and the risk is aggravated in women with BMI ≥30 kg/m2. STUDY FUNDING/COMPETING INTEREST(S): Funding in Denmark was from the Region of Southern Denmark, Overlægerådet, Odense University Hospital. Funding in Finland was from Novo Nordisk Foundation, Finnish Research Council and Sigrid Juselius Foundation, the National Regional Fund, Sakari Alhopuro Foundation and Finnish Diabetes Research Foundation. E.E. has received a research grant from Ferring Pharmaceuticals (payment to institution) and serves as medical advisor for Tilly AB, not related to this manuscript.

RESUMO

Background: Endometrial CD138+ plasma cells serve as a diagnostic biomarker for endometrial inflammation, and their elevated occurrence correlates positively with adverse pregnancy outcomes. Infertility-related conditions like polycystic ovary syndrome (PCOS) and recurrent implantation failure (RIF) are closely associated with systemic and local chronic inflammatory status, wherein endometrial CD138+ plasma cell accumulation could also contribute to endometrial pathology. Current methods for quantifying CD138+ cells typically involve laborious and time-consuming microscopic assessments of only a few random areas from a slide. These methods have limitations in accurately representing the entire slide and are susceptible to significant biases arising from intra- and interobserver variations. Implementing artificial intelligence (AI) for CD138+ cell identification could enhance the accuracy, reproducibility, and reliability of analysis. Methods: Here, an AI algorithm was developed to identify CD138+ plasma cells within endometrial tissue. The AI model comprised two layers of convolutional neural networks (CNNs). CNN1 was trained to segment epithelium and stroma across 28,363 mm2 (2.56 mm2 of epithelium and 24.87 mm2 of stroma), while CNN2 was trained to distinguish stromal cells based on CD138 staining, encompassing 7345 cells in the object layers (6942 CD138- cells and 403 CD138+ cells). The training and performance of the AI model were validated by three experienced pathologists. We collected 193 endometrial tissues from healthy controls (n = 73), women with PCOS (n = 91), and RIF patients (n = 29) and compared the CD138+ cell percentages based on cycle phases, ovulation status, and endometrial receptivity utilizing the AI model. Results: The AI algorithm consistently and reliably distinguished CD138- and CD138+ cells, with total error rates of 6.32% and 3.23%, respectively. During the training validation, there was a complete agreement between the decisions made by the pathologists and the AI algorithm, while the performance validation demonstrated excellent accuracy between the AI and human evaluation methods (intraclass correlation; 0.76, 95% confidence intervals; 0.36-0.93, p = 0.002) and a positive correlation (Spearman's rank correlation coefficient: 0.79, p < 0.01). In the AI analysis, the AI model revealed higher CD138+ cell percentages in the proliferative phase (PE) endometrium compared to the secretory phase or anovulatory PCOS endometrium, irrespective of PCOS diagnosis. Interestingly, CD138+ percentages differed according to PCOS phenotype in the PE (p = 0.03). On the other hand, the receptivity status had no impact on the cell percentages in RIF samples. Conclusion: Our findings emphasize the potential and accuracy of the AI algorithm in detecting endometrial CD138+ plasma cells, offering distinct advantages over manual inspection, such as rapid analysis of whole slide images, reduction of intra- and interobserver variations, sparing the valuable time of trained specialists, and consistent productivity. This supports the application of AI technology to help clinical decision-making, for example, in understanding endometrial cycle phase-related dynamics, as well as different reproductive disorders.

RESUMO

OBJECTIVE: This population-based follow-up study investigated register-based disease diagnoses and medication use up till age of 50 years among women with polycystic ovary syndrome (PCOS) that were identified from a population-based birth cohort. DESIGN: Population-based longitudinal cohort study. PATIENTS: Women reporting oligo/amenorrhea and hirsutism at age 31 and/or who were diagnosed with PCOS by a physician by age 46 (n = 244) and women without PCOS symptoms or diagnosis (n = 1556) in the Northern Finland Birth Cohort 1966. MAIN OUTCOME MEASURES: National register data on diagnosed diseases (International Statistical Classification of Diseases [ICD]-8-10) and medication use (Anatomical Therapeutic Chemical) until the age of 50. RESULTS: Women with PCOS had a 26% higher risk for any registered diagnosis (risk ratio [RR]: 1.26 [1.09-1.46]) and a 24% higher risk for medication use (RR: 1.24 [1.05-1.46]) compared with non-PCOS women, even after adjusting for several confounders. Several main ICD categories were more prevalent among women with PCOS versus non-PCOS controls, eg, endocrine, metabolic, nervous system, musculoskeletal, and genitourinary diseases in addition with different symptoms and injuries. Surprisingly, even though the overall morbidity was only increased in women with PCOS with a body mass index (BMI) ≥ 25 kg/m2, there were several ICD main categories that showed higher comorbidity risk especially in women with PCOS with a BMI < 25 kg/m2. Several medications were prescribed more often to women with PCOS versus non-PCOS controls, eg, medications related to the alimentary tract and metabolism, the cardiovascular system, genitourinary system drugs and sex hormones, dermatologic and hormonal preparations, and medications to treat the musculoskeletal, nervous, and respiratory systems. CONCLUSION: Women with PCOS are burdened with multimorbidity and higher medication use, independent of BMI and other confounders. Accordingly, preventive strategies are needed to alleviate the disease burden and improve the health outcomes of women with PCOS.

RESUMO

The 2023 international evidence-based guideline update for the assessment and management of polycystic ovary syndrome (PCOS) recommends using the Rotterdam criteria for the diagnosis of PCOS. The updated guideline has evidence-based recommendation for the diagnosis, and it now also includes serum anti-Müllerian hormone (AMH) measurement as an alternative tool for gynecological ultrasound to diagnose polycystic ovary morphology (PCOM). The aim of this new recommendation was to facilitate PCOS diagnostic workup in primary care and other disciplines, as currently most diagnosing is done in gynecology and infertility clinics. Here, we review factors affecting AMH levels as well as the utility of AMH in PCOS diagnosis. We identified relevant studies that report different cut-offs for AMH to diagnose PCOM as part of PCOS diagnosis. There are, however, some limitations when using AMH that should be acknowledged. These include physiological aspects like age, ethnicity, and obesity and iatrogenic causes like hormonal medication and ovarian surgery. Also reference ranges are different depending on AMH assay used. As a summary, we conclude that AMH is a usable tool in PCOM diagnostics, but it does not have a single cut-off. Therefore, further studies are needed to establish age and assay-based reference ranges.
