Referral Bias

ObjectiveWomen with polycystic ovary syndrome (PCOS) seeking health care in the United States may be more obese and hyperandrogenic than those present in the general population. We aimed to assess the impact of referral bias on European women with functional androgen excess disorders.DesignCross-sectional study.MethodsWe studied two groups of patients: i) 368 consecutive patients referred to our clinic for the study of functional hyperandrogenism (FH) (referral patients); ii) 57 consecutive premenopausal patients identified by screening during blood donation (unselected patients). We compared the anthropometric data from the groups of patients with those of two control populations: iii) a group of unselected premenopausal healthy female blood donors (unselected controls); and iv) data available from the local general premenopausal female population.ResultsReferral patients with FH were more hirsute, had a higher percentage of hyperandrogenemia, and fulfilled PCOS criteria more frequently than unselected patients. The prevalence of obesity in unselected controls was similar to that observed in the general population, whereas referral patients and unselected patients were more frequently obese. The prevalence of obesity was also higher among referral patients compared to unselected patients.ConclusionReferral bias influences the phenotype of patients with FH. Patients studied at the clinical setting may show more severe hyperandrogenic and obese phenotypes than patients from the general population, even though PCOS appears to be associated with weight excess also in the general European population. This fact should be considered when establishing reference values and control populations for clinical and research purposes.

In Pregnancy

Pregnancy hypertensive disorders such as Preeclampsia (PE) are strongly correlated with insulin resistance, a condition in which the metabolic handling of D-glucose is deficient. In addition, the impact of preeclampsia is enhanced by other insulin-resistant disorders, including polycystic ovary syndrome and obesity. For this reason, there is a clear association between maternal insulin resistance, polycystic ovary syndrome, obesity and the development of PE. However, whether PE is a consequence or the cause of these disorders is still unclear. Insulin therapy is usually recommended to pregnant women with diabetes mellitus when dietary and lifestyle measures have failed. The advantage of insulin therapy for Gestational Diabetes Mellitus (GDM) patients with hypertension is still controversial; surprisingly, there are no studies in which insulin therapy has been used in patients with hypertension in pregnancy without or with an established GDM. This review is focused on the use of insulin therapy in hypertensive disorders in the pregnancy and its effect on offspring and mother later in life. PubMed and relevant medical databases have been screened for literature covering research in the field especially in the last 5-10 years.

AbstractPolycystic ovary syndrome (PCOS) is the most common reproductive endocrine disorder in pre-menopausal women having complex pathophysiology. Several candidate genes have been shown to have association with PCOS. CYP19 gene encodes a key steroidogenic enzyme involved in conversion of androgens into estrogens. Previous studies have reported contradictory results with regard to association of SNP rs2414096 in CYP19 gene with PCOS and hyperandrogenism in different ethnic populations. Present study was aimed to investigate the impact of SNP rs2414096 polymorphism of CYP19 gene on susceptibility of PCOS and hyperandrogenism in Kashmiri women. Further we also studied the genotypic-phenotypic association for various clinical and biochemical parameters of this polymorphism. Case control study. 394 PCOS cases diagnosed on the basis of Rotterdam criteria and age matched 306 healthy women. We found a significant differences in genotypic frequency (χ2 = 18.91, p < 0.05) as well as allele frequency (OR 0.63, CI 0.51–0.78, χ2 = 17.66, p < 0.05) between PCOS women and controls. The genotype–phenotype correlation analysis showed a significant difference in FG score (p = 0.047) and alopecia (p = 0.045) between the three genotypes. Also, the androgen excess markers like DHEAS (p < 0.001), Androstenedione (p < 0.001), Testosterone (p < 0.001) and FAI (p = 0.005) were significantly elevated in GG genotype and showed a significant difference in additive model in PCOS women. rs2414096 polymorphism of CYP19 gene is associated with the risk of PCOS as well as with clinical and biochemical markers of hyperandrogenism, hence suggesting its role in clinical manifestations of PCOS in Kashmiri women.

AbstractPolycystic ovary syndrome (PCOS) in an intricate disorder characterized by reproductive and metabolic abnormalities that may affect bone quality and strength along with the lifespan. The present study analysed the impact of postnatal androgenization (of a single dose of testosterone propionate 1.25 mg subcutaneously at day 5 of life) on bone development and markers of bone metabolism in adult female Wistar rats. Compared with healthy controls, the results of measurements of micro-computed tomography (microCT) of the distal femur of androgenized rats indicated an increased cortical bone volume voxel bone volume to total volume (VOX BV/TV) and higher trabecular number (Tb.n) with reduced trabecular separation (Tb.sp). A large magnitude effect size was observed in the levels of circulating bone formation Procollagen I N-terminal propeptide (P1NP) at day 60 of life; reabsorption cross-linked C-telopeptide of type I collagen (CTX) markers were similar between the androgenized and control rats at days 60 and 110 of life. The analysis of gene expression in bone indicated elements for an increased bone mass such as the reduction of the Dickkopf-1 factor (Dkk1) a negative regulator of osteoblast differentiation (bone formation) and the reduction of Interleukin 1-b (Il1b), an activator of osteoclast differentiation (bone reabsorption). Results from this study highlight the possible role of the developmental programming on bone microarchitecture with reference to young women with PCOS.

Abstract Context Polycystic ovary syndrome (PCOS) is the most common endocrine disorder of reproductive-aged women, affecting approximately 5-20% of women of reproductive age. A previous estimate noted that the economic burden of PCOS approximates $3.7 billion annually in 2020 USD when considering only the costs of the initial diagnosis and of reproductive endocrine morbidities, not considering the costs of pregnancy-related and long-term morbidities. Objective To estimate the excess prevalence and economic burden of pregnancy-related and long-term health morbidities attributable to PCOS. Data Sources PubMed, EmBase and Cochrane Library. Study Selection Studies in which the diagnosis of PCOS was consistent with the Rotterdam, National Institutes of Health (NIH), or Androgen Excess & PCOS (AE-PCOS) Society criteria, or that used electronic medical record diagnosis codes, or diagnosis based on histopathologic sampling were eligible for inclusion. Studies that included an outcome of interest and a control group of non-PCOS patients who were matched or controlled for body mass index (BMI) were included. Data Extraction Two investigators working independently extracted data on study characteristics and outcomes. Data Synthesis Data was pooled using random-effects meta-analysis. The I 2statistic was used to assess inter-study heterogeneity. The quality of selected studies was assessed using the Newcastle-Ottawa Scale. Results The additional total healthcare-related economic burden due to pregnancy-related and long-term morbidities associated with PCOS in the United States is estimated to be $4.3 billion annually in 2020 USD. Conclusions Together with our prior analysis, the economic burden of PCOS is estimated at $8 billion annually in 2020 USD.

The Impact

AbstractThe association between subclinical hypothyroidism (SCH) and polycystic ovary syndrome (PCOS) has been shown in many studies. These findings are still controversial, however. It is unclear whether the co-incidence of subclinical hypothyroidism and polycystic ovary syndrome will affect the severity of metabolism. Therefore, we performed this meta-analysis to investigate the association. A comprehensive search strategy was developed to obtain all relevant studies published in PubMed, EMBASE, Cochrane Library, and Chinese Academic Journal Full-text Database (CNKI) up to 31 December 2020. We adopted the standardized mean difference (SMD) with 95% confidence intervals (CI) for evaluation, and sensitivity analysis was performed. Publication bias was analyzed and represented by a funnel plot, and funnel plot symmetry was assessed with Egger’s test. Twenty-seven studies with 4821 participants (1300 PCOS patients with SCH, 3521 PCOS patients without SCH) were included in the present meta-analysis,among which 71.31% chinese patients out of the total. The results showed that PCOS patients with SCH had higher levels of HOMA-IR, TG, TC, LDL, FBG, FCP, PRL and lower levels of HDL, LH and T. It also recognized the limitation of the lack of a consistent definition of hypothyroidism in the 27 studies included. The results of this study indicated that SCH may aggravate lipid and glucose metabolism in patients with PCOS.

Treatment Of Obesity

Polycystic ovary syndrome (PCOS) is a common disorder affecting women of reproductive age and it is associated with increased cardiovascular risk. Obesity plays an important role in the pathogenesis of PCOS, and the majority of patients with PCOS are obese. Over the last 20 years, the prevalence of obesity has dramatically increased, with probable associated increase in PCOS. Weight reduction plays an integral part in the management of women with PCOS. In this paper, current available weight reduction therapies in the management of PCOS are discussed.
