Abstract

:Data on eating disorders in women with PCOS is insufficient. The objective of this case study was to examine the hypothesis that women with PCOS exhibit more impaired eating than healthy women. Women diagnosed with PCOS under the 2003 Rotterdam Diagnostic Criteria (n = 40) were compared with a healthy control group (n = 40). The groups also were divided into two as normal body weight and overweight/obese. The Eating Disorders Assessment Questionnaire (EDE-Q) and the Three Factor Eating Questionnaire (TFEQ-R21), were completed by all participants in order to evaluate eating behaviors in addition to eating disorders. Among the overweight/obese group, the average total and subscale scores of the EDE-Q as well as the total and sub-factor scores of the TFEQ-R21 were higher in women with PCOS compared to controls (p < .05). However, this statistically significant result was not shown among the women with normal weight (p > .05). In comparison to the controls, the PCOS women displayed higher values of the tool scores indicating abnormal restraint eating, body shape concern and weight concern subscale scores (p < .05). This result suggests that the evaluation of eating disorders should be added to routine screening and the monitoring of women with PCOS.

摘要

: PCOS 妇女进食障碍的数据不足。本病例研究的目的是检验 PCOS 女性比健康女性表现出更多饮食受损的假设。根据 2003 鹿特丹诊断标准诊断为 PCOS 的妇女 (n = 40) 与健康对照组 (n = 40) 进行比较。这些组也被分为正常体重和超重/肥胖两组。所有参与者填写进食障碍评估问卷 (EDE-Q) 和三因素饮食问卷 (TFEQ-R21),以评估进食障碍之外的饮食行为。在超重/肥胖组中,PCOS 患者 EDE-Q 量表的平均总分和分量表得分以及 TFEQ-R21 的总分和分量表得分均高于对照组 (p <.05)。然而,在体重正常的女性中,这一统计学显著性结果并未显示 (p>.05)。与对照组相比,PCOS 妇女表现出更高的工具评分值,表明异常约束进食、体型关注和体重关注分量表评分 (p <.05)。这一结果提示,在常规筛查和 PCOS 妇女的监测中应增加对进食障碍的评估。

METHODS:Polycystic Ovary Syndrome (PCOS) is the most common endocrine disorder amongst women of reproductive age, whose aetiology remains unclear. To improve our understanding of the molecular mechanisms underlying the disease, we conducted a genome-wide DNA methylation profiling in granulosa lutein cells collected from 16 women suffering from PCOS, in comparison to 16 healthy controls. Samples were collected by follicular aspiration during routine egg collection for IVF treatment. Study groups were matched for age and BMI, did not suffer from other disease and were not taking confounding medication. Comparing women with polycystic versus normal ovarian morphology, after correcting for multiple comparisons, we identified 106 differentially methylated CpG sites with p-values <5.8 × 10 that were associated with 88 genes, several of which are known to relate either to PCOS or to ovarian function. Replication and validation of the experiment was done using pyrosequencing to analyse six of the identified differentially methylated sites. Pathway analysis indicated potential disruption in canonical pathways and gene networks that are, amongst other, associated with cancer, cardiogenesis, Hedgehog signalling and immune response. In conclusion, these novel findings indicate that women with PCOS display epigenetic changes in ovarian granulosa cells that may be associated with the heterogeneity of the disorder.

METHODS::Introduction: Approximately 1% of adolescents have polycystic ovary syndrome (PCOS) and almost 40-70% of these patients are overweight or obese. Obese adolescents with PCOS have more severe insulin resistance and hyperandrogenemia, a more adverse lipid profile and a worse quality of life than normal-weight adolescents with PCOS. Accordingly, weight loss is an important component of the management of these patients.Areas covered: The authors discuss the different options for weight loss in obese adolescents with PCOS. Lifestyle changes appear to be effective but adherence to this intervention is suboptimal. There are also limited data regarding the optimal diet in this population. Few small studies have evaluated the effects of pharmacotherapy in these patients. Conflicting data have been reported regarding the effects of metformin on body weight. Notably, agents that have been approved for weight loss in adults have not been evaluated in adolescents with PCOS.Expert opinion: More studies are needed to identify the most appropriate diet for obese adolescents with PCOS. Well-designed randomized controlled studies are also needed to define the safety and efficacy of pharmacotherapy in this population.

METHODS::Polycystic ovary syndrome (PCOS) is a hormonal disorder common among women of reproductive age. Although much is understood concerning the pathology of PCOS, further investigation into the influence of microribonucleic acids (miRNAs) on the proliferation of ovarian granulosa cells (GCs) is needed. This study investigated the role of specific miRNAs in ovarian dysfunction of PCOS and its effect on the proliferation of GCs. Initially, miRNA profiling was performed on the ovarian cortexes of 15 rats in which PCOS had been induced and 15 rats without PCOS (non-PCOS). This mechanical study was performed on ovarian GCs extracted from human chorionic gonadotrophin (hCG)-induced rats. Insulin was used to treat GCs to establish the PCOS cell model. Increased Equus caballus mir-9119 expression was observed and confirmed in the insulin-induced model of PCOS in GCs (GC-PCOS) as well as in the hCG-induced rats when compared to non-PCOS rats and cells. Observation and confirmation were carried out through both miRNA array and quantitative PCR. In contrast, downregulation of the nuclear factor kappa B (NFκB) p65 was observed in the PCOS cell model. Additionally, annexin V, FITC, and propidium iodide flow cytometry showed overexpression of miR-9119-induced apoptosis. In this study, we revealed that miR-9119 inhibition regulates p65 expression levels in insulin-treated GCs by binding to the 3'-untranslated of p65. Additionally, regulation of p65 expression was positively correlated with the expression of the double-stranded RNA endoribonuclease DICER. Moreover, RNA silencing/overexpression of p65 affected the functional role of miR-9119. In conclusion, GCs of PCOS, the expression of miR-9119, and targeted NFκB/p65-DICER axis are upregulated in order to maintain cell viability and prevent apoptosis, thereby promoting Anti-Müllerian hormone production in GCs. This study may provide a new understanding of the mechanism of GC dysfunction.
