Alghamdi AA, Alotaibi AS. High Insulin Resistance in Saudi Women with Unexplained Recurrent Pregnancy Loss: A Case-control Study. SAUDI JOURNAL OF MEDICINE & MEDICAL SCIENCES 2023; 11:314-318. [PMID: 37970461 PMCID: PMC10634469 DOI: 10.4103/sjmms.sjmms_82_23] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Subscribe] [Scholar Register] [Received: 02/25/2023] [Revised: 06/23/2023] [Accepted: 08/14/2023] [Indexed: 11/17/2023]
Abstract
Background Unexplained recurrent pregnancy loss (RPL) accounts for >50% of the patients with RPL. Insulin resistance (IR) is a potential cause of unexplained RPL. Objectives To evaluate the relationship between insulin resistance (IR) and unexplained RPL among Saudi women. Methods This is a single-center, case-control study conducted at a tertiary hospital in the Eastern Province of Saudi Arabia. The study group comprised Saudi women with unexplained RPL, while the control group had Saudi women with at least one live birth and no RPL. Blood samples were taken to determine the fasting glucose (FG) and fasting insulin (FI) levels. Women with diabetes mellitus and polycystic ovarian syndrome were excluded. A homeostatic model assessment of insulin resistance index (HOMA-IR) value ≥3 was considered as IR. Results The study and control groups comprised 43 and 56 women, respectively. Between the groups, there was a significant difference in the mean age (case: 37.9 ± 5.4 years; control: 32.2 ± 5.9 years; P < 0.0001) and the mean BMI (case: 31.5 ± 6.0; control: 26.1 ± 2.8; P < 0.0001). FG level was slightly higher in the control group (90.9 mg/dL vs 88.7 mg/dL; P = 0.068). FI level was significantly higher in the study group (16.33 μU/mL vs. 6.17 μU/mL; P < 0.0001). HOMA-IR of ≥3 was significantly more common in the study group (n = 22; 51.2%) than the control group (4; 7.1%) (P < 0.0001). After adjusting for age and BMI, IR ≥3 was found to be independently associated with unexplained RPL (aOR: 13.2; 95% CI: 3.77-46.36). Conclusions This study showed that Saudi women with unexplained RPL had significantly higher levels of fasting insulin and insulin resistance than those without a history of RPL. Therefore, it is recommended to assess IR in women with RPL.

Abstract
Aim The incidence of gestational diabetes mellitus is increasing worldwide. Biotin is shown to improve glycemic status in diabetes mellitus. We wanted to study whether there is a difference in biotin levels between mothers with and without gestational diabetes mellitus (GDM), association of biotin with blood glucose, and with the outcome of GDM. Methods We recruited 27 pregnant mothers with GDM and 27 pregnant mothers without GDM. We measured the biotin levels using enzyme linked immunosorbent assay (ELISA). We measured the blood glucose during OGTT and fasting insulin levels in the study participants. Results We found that biotin levels were slightly decreased in mothers with GDM [271 (250,335)] as compared to control mothers [309 (261,419)], though it was not statistically significant (p = 0.14). Blood glucose levels were found to be significantly higher in GDM mothers as compared to control mothers during fasting, 1 h and 2 h plasma sample obtained during OGTT. Biotin was not significantly associated with blood glucose in pregnant mothers. Logistic regression analysis showed that biotin (OR = 0.99, 95 % CI = 0.99-1.00) has no association with the outcome of GDM. Conclusion Ours is the first study to compare the biotin levels in GDM mothers and control mothers. We found that the biotin levels were not significantly altered in GDM mothers as compared to control mothers and biotin levels have no association with the outcome of GDM.

What is the impact of vitamin D supplementation on glycemic control in people with type-2 diabetes: a systematic review and meta-analysis of randomized controlled trails. BMC Endocr Disord 2023; 23:15. [PMID: 36647067 PMCID: PMC9841647 DOI: 10.1186/s12902-022-01209-x] [Citation(s) in RCA: 13] [Impact Index Per Article: 13.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/19/2022] [Accepted: 11/10/2022] [Indexed: 01/18/2023] Open
Abstract
BACKGROUND There is conflicting evidence on the effect of vitamin D on glycemic control. Therefore, in the current meta-analyses, we aimed to assess the effect of vitamin D supplementation on the glycemic control of type 2 diabetes (T2D) patients. METHODS We conducted a comprehensive search in electronic databases including; PubMed/Medline, Web of Science, Scopus, Embase, Cochrane Central Register of Controlled Trials (CENTRAL), and NIH's Clinical Trials Registry, from the inception of each database up to January first, 2021. RESULTS A total of 46 randomized controlled trials (RCTs) consisting of 2164 intervention subjects and 2149 placebo controls were included in this meta-analysis. Pooled analyses for HbA1c showed a significant change between the intervention and placebo group, the weighted mean difference (WMD)(95% confidence interval(CI)) was -0.20%(-0.29, -0.11) with P < 0.001. Analyses for assessing changes in FPG found a significant reduction in the intervention group after vitamin D supplementation, the WMD (95%CI) was -5.02 mg/dl (-6.75,-3.28) with P < 0.001. The result of pooled analyses for HOMA-IR revealed a significant change between the intervention and control group, the WMD (95%CI) was -0.42(-0.76, -0.07) with P = 0.019. The subgroup analyses showed the most efficacy in a higher dose and short intervention period and in subjects with deficient vitamin D status. CONCLUSION Vitamin D supplementation might be beneficial for the reduction of FPG, HbA1c, and HOMA-IR in type 2 diabetes patients with deficient vitamin D status. This effect was especially prominent when vitamin D was given in large doses and for a short period of time albeit with substantial heterogeneity between studies and a probability of publication bias.

[PMID: 36760577 PMCID: PMC9901483 DOI: 10.2147/dmso.s399105] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/25/2022] [Accepted: 01/24/2023] [Indexed: 02/05/2023] Open
Abstract
BACKGROUND Insulin resistance (IR) may adversely impact the in vitro fertilization (IVF) or intracytoplasmic sperm injection (ICSI) outcomes. However, the association of IR with ovarian sensitivity during controlled ovarian hyperstimulation (COH) remains controversial. PURPOSE We aimed to explore the association between homeostasis model assessment of insulin resistance (HOMA-IR) and ovarian sensitivity index (OSI). PATIENTS AND METHODS In this retrospective cohort study, 7836 patients aged between 20 and 39 years with good ovarian reserve were included consecutively between June 2018 and May 2022. HOMA-IR was calculated to evaluate the degree of IR and OSI was used to measure ovarian sensitivity. Owing to skewed distribution, HOMA-IR and OSI were log e transformed to Ln HOMA-IR and Ln OSI. Smoothing splines were generated by generalized additive models to explore the correlation between Ln HOMA-IR and Ln OSI. Then, the relationship between Ln HOMA-IR and Ln OSI was tested with multivariable linear regression model after adjustments for the potential confounders. RESULTS We observed negative association between Ln HOMA-IR and Ln OSI after adjustment for potential confounders by using smoothing spline fitting curves in generalized additive model. In the multivariable linear regression model, after full adjustments, each one unit increase in Ln HOMA-IR was related to reduced Ln OSI values (β = -0.12, 95% CI, -0.15, -0.09). As sensitivity analysis, those who had HOMA-IR of quartile 3 (HOMA-IR 2.33-3.43) and quartile 4 (HOMA-IR ≥3.43) had decreases in Ln OSI values (β = -0.07, 95% CI -0.11, -0.03 and β = -0.18, 95% CI -0.22, -0.13, respectively) when compared with patients in the quartile 1 (HOMA-IR <1.63). Furthermore, stratified and interaction analysis showed a strong inverse association of Ln HOMA-IR with Ln OSI in subgroups of PCOS patients and overweight/obese populations (P-value for interaction <0.0001). CONCLUSION HOMA-IR value was negatively associated with the ovarian sensitivity assessed by OSI. Among the PCOS and overweight/obese populations, this inverse relationship may be strong. These findings will increase the understanding of the contribution of IR to the development of decreased ovarian sensitivity within the assisted reproductive technology (ART) setting. It may have implications for optimizing gonadotropin dose manipulation in patients with IR undergoing IVF/ICSI.

Abstract
We investigated selected pro/antioxidant parameters in a group of women with polycystic ovary syndrome (PCOS) divided according to age, body mass index (BMI), waist-to-hip ratio (WHR), homeostatic model assessment for insulin resistance (HOMA-IR) and quantitative insulin sensitivity check index (Quicki). We chose oxidized low-density lipoproteins (oxLDL-C) as a marker of oxidative stress and the ferric reducing ability of plasma (FRAP) as a marker of antioxidant status. In women with PCOS, the values of BMI, WHR, age and concentration of glucose significantly affected oxLDL-C concentration and FRAP values. FRAP correlated with oxLDL-C level in the whole group and in women who were insulin sensitive (HOMA-IR < 2.0). There was a negative relationship between the concentration of Anti-Müllerian hormone and both oxLDL-C and FRAP. Furthermore, the value of FRAP was inversely correlated with luteinizing hormone (LH), follicle-stimulating hormone (FSH) and androstenedione, whereas it was positively correlated with the LH/FSH ratio. The concentration of oxLDL and the value of FRAP are significantly associated with selected metabolic and hormonal parameters in the course of PCOS.

Abstract
Objective The objective of the study was to explore the effect of insulin resistance on pregnancy outcomes in patients with polycystic ovary syndrome (PCOS) from the first embryo transfer cycle. Design This was a single-center, retrospective, observational cohort study. Patients Included in the study were women with PCOS for the first embryo transfer. Main Outcome Measures Early miscarriage rate and macrosomia rate were the main outcome measures. Results With increased HOMA-IR, the early miscarriage rate (7.14, 13.21, and 16.22%, respectively; P = 0.039), macrosomia rate (5.78, 11.79, and 17.58%, respectively; P = 0.026) and the incidence of gestational diabetes (GDM) (10.00, 14.50, and 25.67% respectively; P = 0.002) significantly increased, while the live birth rate markedly decreased (63.03, 55.27, and 47.88%, respectively; P = 0.004). No significant difference was found in clinical pregnancy rate, late miscarriage rate, low birthweight rate and baby gender ratio (all P >0.05). After adjusting for confounding factors, HOMA-IR was an independent risk factor of early miscarriage rate and macrosomia rate. Conclusion Insulin resistance is an independent risk factor for early miscarriage and macrosomia in PCOS patients during the first embryo transfer cycle. It is essential to give more attention before and after pregnancy for PCOS women with high HOMA-IR.

Abstract
BACKGROUND Moving from the correlation between insulin-resistance and PCOS, metformin has been administered in some PCOS women improving ovulatory and metabolic functions and decreasing androgen levels. Inconsistency and unpredictability of response to metformin limit its extensive use. Aim of this study was to identify reliable predictors of response to metformin therapy for weight loss and reduction in plasma androgen levels using ANNs (artificial neural networks). METHODS One hundred eight consecutive women with PCOS (ESHRE/ASRM 2003 Rotterdam criteria) treated with metformin 1500 mg/day, at inclusion and every 6 months underwent to a complete clinical, endocrine/metabolic assessment and ultrasonographic evaluation. Therapy outcomes were BMI reduction (≥1 kg/m2) in overweight/obese and free-androgen-index (FAI) decrease (≥1%) in hyperandrogenemic women. Semantic connectivity maps (SCMs) were obtained through Auto-CM, a fourth generation ANN, to compare patients' baseline clinical features to the treatment outcomes. Multivariate logistic regression analysis was used to assess the major predictor in drop-out patients and the associated risk. RESULTS At 6 months 54 out of 103 (52,4%) obese patients showed BMI reduction and 45 out of 89 (50,6%) hyperandrogenemic women showed FAI decrease. The further response rates at 12 months were 30,6 and 47%, respectively. SCMs showed a clear polarization for both the outcomes with elevated accuracy. Treatment responsiveness resulted strictly related to oligo-amenorrhea and hyperandrogenemia at baseline. In addition, lower serum testosterone levels at baseline were found to be the major predictor of treatment discontinuation. CONCLUSIONS In women with PCOS, menstrual pattern imbalance and ovarian androgens excess are the best predictors of metformin response. They may pave the way for a rethinking of the criteria for evaluating hyperandrogenism in order to better define the large population included in the diagnosis of PCOS. Baseline plasma testosterone level can serve as a sensitive marker to predict treatment compliance.

Abstract
This study aimed to evaluate the efficacy of SHBG in predicting insulin resistance (IR) in newly diagnosed, untreated patients with polycystic ovary syndrome (PCOS). Hundred newly diagnosed, untreated patients with PCOS and 61 subjects without PCOS (41 healthy volunteers with normal BMI and 20 subjects with overweight/obese) were included in the study. Receiver-operating characteristic (ROC) analysis was used to assess the effectiveness of SHBG in predicting IR in overweight/obese and non-overweight PCOS patients and the optimal cut-off values of SHBG. The results showed negative correlations between log-SHBG and log-I0 (r = - 0.372, P < 0.001) and log-SHBG and log-Homeostatic Model Assessment of Insulin Resistance (HOMA-IR) (r = - 0.393, P < 0.001) after adjusting for blood pressure, serum lipid, age, and body mass index (BMI) in all of the PCOS patients. In patients with IR (defined as HOMA-IR ≥2.29), the area under the ROC curves (AUCs) of the SHBG for ROC analysis in the non-overweight group, overweight/obese group, and all PCOS patients were 0.774 (P = 0.0001), 0.922 (P = 0.0001), and 0.885 (P = 0.0001), respectively. The optimal cut-off value of SHBG was 37 nmol/L with a sensitivity of 97.62% and specificity of 80.85% in the overweight group. In patients with IR (HOMA-IR ≥2.5), the AUCs of SHBG for ROC analysis in the non-overweight group, overweight/obese group, and all PCOS patients were 0.741 (P = 0.0003), 0.928 (P = 0.0001), and 0.880 (P = 0.0001), respectively. The optimal cut-off value of SHBG was 30.2 nmol/L with a sensitivity of 97.44% and specificity of 82.69% in the overweight/obese group. In conclusion, this study observed a negative correlation between SHBG and HOMA-IR in PCOS patients after adjustment of confounding factors. SHBG was an independent influential factor of HOMA-IR and can be used as a positive predictive marker for IR in PCOS patients, especially in those who are overweight/obese.

Implementation of the polycystic ovary syndrome guidelines: A mixed method study to inform the design and delivery of a lifestyle management program for women with polycystic ovary syndrome. Nutr Diet 2021; 78:476-486. [PMID: 33876532 DOI: 10.1111/1747-0080.12670] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/03/2020] [Revised: 02/11/2021] [Accepted: 03/12/2021] [Indexed: 12/15/2022]
Abstract
AIM The 2018 evidence-based polycystic ovary syndrome (PCOS) guidelines recommend lifestyle management as first-line treatment. This study aims to understand the preferred intervention characteristics of a PCOS lifestyle program from the perspectives of women with PCOS to inform the translation of the guidelines into practice. METHODS Women with self-reported PCOS residing in Australia took part in semi-structured interviews (n = 20) and an online survey (n = 286). The survey and interview schedule were developed using the template for intervention description and replication checklist. RESULTS Women want to take part in a lifestyle program (94.6%) and use government-subsidised sessions to attend (83%). Sessions of 45 to 60 minutes (75%) costing less than AUD$50 are preferred (60%). Topics of most interest related to sustainable daily physical activity (58%), overcoming non-hungry eating (54%), PCOS-specific diets (51%) and how to overcome barriers to behaviour change (45%). A delivery mode that combines online and in-person support is preferred (53%). Women are in need of long-term professional lifestyle support (6-12 months) that provides evidence-based, PCOS-specific, personalised prescription. Multidisciplinary support from a range of PCOS-trained professions is also preferred to address women's physical, psychological and emotional needs. CONCLUSION Women with PCOS are willing to take part in lifestyle programs that are low cost, long term, evidence based, PCOS-specific and provide practical strategies for nutrition and physical activity changes. Future online and in-person PCOS programs are strongly recommended to incorporate these findings to improve program engagement and patient satisfaction.

Abstract
The aim of this study was to assess concentration of zinc (Zn), copper (Cu), and sirtuin 1 (SIRT1) in serum of women with polycystic ovary syndrome (PCOS) and their relationships with glucose metabolism parameters. The study included 76 women with PCOS aged between 17 and 39 years old. The blood was collected according to the routine procedure during the follicular phase. Zn and Cu concentrations were performed by flame atomic absorption spectrometry (FAAS). Glucose concentration was estimated by colorimetric methods. Insulin (INs) concentration was determined by enzyme-linked immunosorbent assay. SIRT1 concentration was determined using commercial test. We found higher Cu concentration and Cu/Zn value in the serum of women with PCOS with overweight/obesity. Early stage of insulin resistance (IR) in the group of women with PCOS affected on higher Cu concentration and Cu/Zn value. However, increased value of body mass index, waist-hip ratio and homeostatic model assessment of insulin resistance (HOMA-IR) was not associated with changes in Zn and SIRT1 concentration. Further disturbances in glucose metabolic parameters in the blood of women with PCOS were intensified by overweight/obesity and IR. Overweight/obesity and IR in the women with PCOS increase disorders in Cu homeostasis and glucose metabolism parameters.

Abstract
Insulin resistance (IR) disrupts ovarian functions in polycystic ovary syndrome (PCOS). The contributing factors remains elusive. High mobility group box 1 (HMGB1), a damage-associated molecular pattern molecule, has been shown to be related to IR and autophagy, respectively, in peripheral tissues. Here, we investigated whether increased HMGB1 contributes to IR in granulosa cells of PCOS patients via induction of aberrant autophagy. Results showed that HMGB1 abundance in the follicular fluid was significantly increased with enhanced autophagy in granulosa cells in PCOS patients with IR. HMGB1 exacerbated autophagy in granulosa cells as evinced by increased LC3B II/I ratio and ATG7 as well as decreased p62, the markers for autophagy. Concurrently, HMGB1 impaired insulin sensitivities by attenuating the abundance of insulin receptor substrate-1, Akt phosphorylation, GLUT4 translocation, and glucose uptake in granulosa cells, which were reversed by blocking autophagy pathways with siRNA-mediated knockdown of ATG7 or with chloroquine and bafilomycin A1, the lysosome inhibitors. In conclusion, our results indicate that increased HMGB1 contributes to IR development in granulosa cells of PCOS patients, which is associated with exacerbation of autophagy by HMGB1. Control of HMGB1 production may be benefical for the improvement of insulin sensitivity in granulosa cells in PCOS.

Abstract
OBJECTIVE Polycystic ovary syndrome (PCOS) is a common endocrine disorder in women of reproductive age. The renal resistive index (RRI) is a measure of renal arterial resistance to blood flow. The aim of this study was to investigate the renal resistive index levels of patients with PCOS. SUBJECTS AND METHODS A total of 216 women were included in this cross-sectional study. The study group consisted of 109 patients with PCOS, and the control group consisted of 107 healthy subjects. The RRI of all subjects was measured using renal Doppler ultrasonography. RESULTS The patients with PCOS had higher RRI levels in comparison to the healthy subjects (0.64 ± 0.06 vs. 0.57 ± 0.06, p < 0.001). The RRI levels of the patients with PCOS were correlated with systolic blood pressure (p = 0.004, r = 0.268) and with homeostasis model assessment of insulin resistance (HOMA-IR) (p = 0.02, r = 0.216). CONCLUSION In this study, we observed higher RRI levels in patients with PCOS. High RRI levels may be an indicator of cardiovascular and/or cardiovascular-associated diseases in patients with PCOS.

Abstract
OBJECTIVE To explore metabolic disturbances in nonobese women with polycystic ovary syndrome (PCOS) compared with nonobese healthy controls. DESIGN Systematic review and meta-analysis. SETTING Not applicable. PATIENT(S) Nonobese women with PCOS and nonobese healthy controls. INTERVENTION(S) None. MAIN OUTCOME MEASURE(S) Prevalence of metabolic disturbances including hyperinsulinemia, insulin resistance (IR), impaired fasting glucose (IFG), impaired glucose intolerance (IGT), prediabetes, dyslipidemia, hypercholesterolemia, hypertriglyceridemia, and low high-density lipoprotein (low-HDL), as well as other metabolic outcomes such as type 2 diabetes mellitus (T2DM), hypertension, metabolic syndrome (Mets), myocardial infarction, stroke, cerebrovascular accident, arterial occlusive disease, and coronary heart disease. RESULT(S) Compared to nonobese controls, nonobese women with PCOS showed a higher prevalence of hyperinsulinemia (odds ratio [OR], 36.27; 95% confidence interval [CI] 1.76-747.12), IR (OR, 5.70; 95% CI 1.46-22.32), IGT (OR, 3.42; 95% CI 1.56-7.52), T2DM (OR, 1.47; 95% CI 1.11-1.93), hypertriglyceridemia (OR, 10.46; 95% CI 1.39-78.56), low-HDL (OR, 4.03; 95% CI 1.26-12.95), and Mets (OR, 2.57; 95% CI 1.30-5.07). No significant difference was observed for IFG, pre-DM, dyslipidemia, hypercholesterolemia, and hypertension. In subgroup analysis, Whites exhibited increased risks of IR, IGT, IFG, T2DM, hypertension, and Mets, whereas no significant metabolic change was found in Asians. No study reported specifically an incidence of myocardial infarction, stroke, cerebrovascular accident, arterial occlusive disease, and coronary heart disease in nonobese women with PCOS. CONCLUSION(S) Nonobese women with PCOS also suffer from metabolic disturbances and the risk of long-term metabolic complications. Further efforts should be made to elucidate underlying mechanisms and possible interventions in the early phase.

Abstract
BACKGROUND Polycystic ovary syndrome (PCOS) affects 8% to 13% of reproductive-aged women and is associated with reproductive and metabolic dysfunction. Obesity worsens the presentation of PCOS and weight management (weight loss, maintenance or prevention of excess weight gain) is proposed as an initial treatment strategy, best achieved through lifestyle changes incorporating diet, exercise and behavioural interventions. OBJECTIVES To assess the effectiveness of lifestyle treatment in improving reproductive, anthropometric (weight and body composition), metabolic and quality of life factors in PCOS. SEARCH METHODS We searched the Cochrane Gynaecology and Fertility Specialised Register, the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, Embase, PsycINFO, CINAHL and AMED (date of last search March 2018). We also searched controlled trials registries, conference abstracts, relevant journals, reference lists of relevant papers and reviews, and grey literature databases, with no language restrictions applied. SELECTION CRITERIA Randomised controlled trials (RCTs) comparing lifestyle treatment (diet, exercise, behavioural or combined treatments) to minimal or no treatment in women with PCOS. DATA COLLECTION AND ANALYSIS Two authors independently selected trials, assessed evidence quality and risk of bias, and extracted data. Our primary outcomes were live birth, miscarriage and pregnancy. We used inverse variance and fixed-effect models in the meta-analyses. We reported dichotomous outcomes as an odds ratio and continuous outcomes as a mean difference (MD) or standardised mean difference (SMD). MAIN RESULTS We included 15 studies with 498 participants. Ten studies compared physical activity to minimal dietary and behavioural intervention or no intervention. Five studies compared combined dietary, exercise and behavioural intervention to minimal intervention. One study compared behavioural intervention to minimal intervention. Risk of bias varied: eight studies had adequate sequence generation, seven had adequate clinician or outcome assessor blinding, seven had adequate allocation concealment, six had complete outcome data and six were free of selective reporting. No studies assessed the fertility primary outcomes of live birth or miscarriage. No studies reported the secondary reproductive outcome of menstrual regularity, as defined in this review.Lifestyle intervention may improve a secondary (endocrine) reproductive outcome, the free androgen index (FAI) (MD -1.11, 95% confidence interval (CI) -1.96 to -0.26, 6 RCTs, N = 204, I2 = 71%, low-quality evidence). Lifestyle intervention may reduce weight (kg) (MD -1.68 kg, 95% CI -2.66 to -0.70, 9 RCTs, N = 353, I2 = 47%, low-quality evidence). Lifestyle intervention may reduce body mass index (BMI) (kg/m2) (-0.34 kg/m2, 95% CI -0.68 to -0.01, 12 RCTs, N = 434, I2= 0%, low-quality evidence). We are uncertain of the effect of lifestyle intervention on glucose tolerance (glucose outcomes in oral glucose tolerance test) (mmol/L/minute) (SMD -0.02, 95% CI -0.38 to 0.33, 3 RCTs, N = 121, I2 = 0%, low-quality evidence). AUTHORS' CONCLUSIONS Lifestyle intervention may improve the free androgen index (FAI), weight and BMI in women with PCOS. We are uncertain of the effect of lifestyle intervention on glucose tolerance. There were no studies that looked at the effect of lifestyle intervention on live birth, miscarriage or menstrual regularity. Most studies in this review were of low quality mainly due to high or unclear risk of bias across most domains and high heterogeneity for the FAI outcome.

Abstract
AIMS To find the prevalence and predictors of nonalcoholic fatty liver disease (NAFLD) in Asian Indian polycystic ovary syndrome (PCOS) women. MATERIALS AND METHODS This is a prospective, cross-sectional study conducted at a tertiary care hospital from South India. Sixty women fulfilling the Rotterdam (2003) criteria for PCOS were recruited for the study. All participants were evaluated with ultrasound abdomen for fatty liver and additional biochemical investigations including fasting plasma glucose, postprandial plasma glucose, serum insulin, lipid profile and liver function tests. RESULTS The mean age of the study population was 24.06 ± 5.9 (range: 15-39) years. Oligomenorrhea, hirsutism and acne were present in 58 (96.7%), 37 (61.7%) and 33 (55%) women. Mean BMI of the study population was 29.5 ± 5.28 (range: 19.95 to 45.44) kg/m2. Fifty (83.3%) women were obese (BMI: ≥ 25 kg/m2). Twenty-three (38.3%) women with PCOS had NAFLD. Three women each had isolated elevation of alanine transaminase (ALT) and aspartate transaminases (AST) whereas three women had elevation of both. All women with elevated transaminases had NAFLD. By univariate analysis, factors associated with NAFLD were serum total cholesterol, serum insulin, HOMA-IR, hyperandrogenism, ALT and AST. On multiple regression analysis using linear regression, HOMA-IR and hyperandrogenemia were the only significant predictors of NAFLD. CONCLUSION Our study reports NAFLD in more than one third of Asian Indian women with PCOS. In addition to insulin resistance (HOMA-IR), hyperandrogenemia is an independent predictor of NAFLD in women with PCOS.

Abstract
In this study, we aimed to investigate serum and follicular fluid (FF) secreted frizzle-related protein-5 (Sfrp-5) levels in nonobese, nonhyperandrogenic patients with polycystic ovary syndrome (PCOS) undergoing in vitro fertilization (IVF), in addition to IVF outcomes. In total, 160 patients undergoing IVF treatment were included in the study: 80 patients diagnosed with PCOS according to the Rotterdam criteria (group I, study) and 80 patients with the etiology of male factor infertility (group II, control). There were statistically significant between-group differences in serum estradiol (E2) levels on the day of hCG administration (2377.00 ± 733.23 vs. 1931.3 ± 1,010.69), the total gonadotropin dose required (2000.63 ± 1,051.87 vs. 1.134.69 ± 286.45), and the total number of retrieved oocytes (8.60 ± 2.06 vs. 11.05 ± 4.39) (p < 0.05). There was also a statistically significant between-group difference in serum and FF Sfrp-5 levels on the day of oocyte retrieval (11.40 ± 2.88 vs. 8.87 ± 1.85, p < 0.001; 11.06 ± 2.30 vs. 9.71 ± 2.15, p = 0.008; respectively). However, there were no between-group differences in fertilization rates, clinical pregnancy rates, and live birth rates (p > 0.05). A correlation analysis showed that serum and FF Sfrp-5 levels were associated with insulin and inflammatory markers (p < 0.05). In a selected population of nonobese, nonhyperandrogenic PCOS patients, there was a significant difference in Sfrp-5 levels of the PCOS group versus those of the control group. Further studies are needed to determine the effects of Sfrp-5 in women with PCOS.

Abstract
CONTEXT Endometrial insulin resistance (IR) may account for the endometrial dysfunction in polycystic ovary syndrome (PCOS). The underlying mechanism remains to be elucidated. OBJECTIVE To investigate whether the abundance of 11β-hydroxysteroid dehydrogenases (11β-HSDs) 1 and 2 and cortisol as well as the insulin signaling pathway are altered in PCOS endometrium and to clarify the relationship between endometrial IR and local cortisol. DESIGN We measured cortisol and cortisone concentrations, 11β-HSD1 and 11β-HSD2, and core insulin signaling molecules in endometrial biopsies collected from non-PCOS and PCOS with or without IR patients on the seventh day after human chorionic gonadotropin injection. We also studied the effects of cortisol on glucose uptake and the insulin signaling pathway in primary cultured endometrial epithelial cells (EECs). RESULTS The cortisol concentration was elevated, whereas 11β-HSD2 expression was diminished in endometrial biopsies obtained from PCOS with IR patients compared with those from non-PCOS and PCOS without IR patients. The implantation rate was relatively impaired and the endometrial insulin signaling pathway was defective in PCOS with IR patients. In addition, cortisol attenuated insulin-stimulated glucose uptake in EECs, which was mediated by inhibition of Akt phosphorylation and glucose transporter type 4 translocation via induction of phosphatase and tensin homolog deleted on chromosome ten (PTEN). CONCLUSIONS Decreased oxidation of cortisol and defects of insulin signaling in endometrium were observed in PCOS with IR patients. The excessive cortisol level, derived from the reduction of 11β-HSD2, might contribute to the development of endometrial IR by inhibiting the insulin signaling pathway via induction of PTEN expression in EECs.

Abstract
BACKGROUND Polycystic ovary syndrome (PCOS) is characterised by infrequent or absent ovulation, and high levels of androgens and insulin (hyperinsulinaemia). Hyperinsulinaemia occurs secondary to insulin resistance and is associated with increased risk of cardiovascular disease and diabetes mellitus. Insulin-sensitising agents such as metformin may be effective in treating PCOS-related anovulation. OBJECTIVES To evaluate the effectiveness and safety of insulin-sensitising drugs in improving reproductive and metabolic outcomes for women with PCOS undergoing ovulation induction. SEARCH METHODS We searched the following databases from inception to January 2017: Cochrane Gynaecology and Fertility Group Specialised Register, CENTRAL, MEDLINE, Embase, PsycINFO and CINAHL. We searched registers of ongoing trials and reference lists from relevant studies. SELECTION CRITERIA We included randomised controlled trials of insulin-sensitising drugs compared with placebo, no treatment, or an ovulation-induction agent for women with oligo and anovulatory PCOS. DATA COLLECTION AND ANALYSIS Two review authors independently assessed studies for eligibility and bias. Primary outcomes were live birth rate and gastrointestinal adverse effects. Secondary outcomes included other pregnancy outcomes, menstrual frequency and metabolic effects. We combined data to calculate pooled odds ratios (ORs) and 95% confidence intervals (CIs). We assessed statistical heterogeneity using the I2 statistic and reported quality of the evidence for primary outcomes using GRADE methodology. MAIN RESULTS We assessed the interventions metformin, clomiphene citrate, metformin plus clomiphene citrate, D-chiro-inositol, rosiglitazone and pioglitazone. We compared these with each other, placebo or no treatment. We included 48 studies (4451 women), 42 of which investigated metformin (4024 women). Evidence quality ranged from very low to moderate. Limitations were risk of bias (poor reporting of methodology and incomplete outcome data), imprecision and inconsistency. Metformin versus placebo or no treatmentThe evidence suggests that metformin may improve live birth rates compared with placebo (OR 1.59, 95% CI 1.00 to 2.51, 4 studies, 435 women, I2 = 0%, low-quality evidence). The metformin group experienced more gastrointestinal side effects (OR 4.76, 95% CI 3.06 to 7.41, 7 studies, 670 women, I2 = 61%, moderate-quality evidence) but had higher rates of clinical pregnancy (OR 1.93, 95% CI 1.42 to 2.64, 9 studies, 1027 women, I2 = 43%, moderate-quality evidence), ovulation (OR 2.55, 95% CI 1.81 to 3.59, 14 studies, 701 women, I2 = 58%, moderate-quality evidence) and menstrual frequency (OR 1.72, 95% CI 1.14 to 2.61, 7 studies, 427 women, I2 = 54%, low-quality evidence). There was no clear evidence of a difference in miscarriage rates (OR 1.08, 95% CI 0.50 to 2.35, 4 studies, 748 women, I2 = 0%, low-quality evidence). Metformin plus clomiphene citrate versus clomiphene citrate alone There was no conclusive evidence of a difference between the groups in live birth rates (OR 1.21, 95% CI 0.92 to 1.59, 9 studies, 1079 women, I2 = 20%, low-quality evidence), but gastrointestinal side effects were more common with combined therapy (OR 3.97, 95% CI 2.59 to 6.08, 3 studies, 591 women, I2 = 47%, moderate-quality evidence). However, the combined therapy group had higher rates of clinical pregnancy (OR 1.59, 95% CI 1.27 to 1.99, 16 studies, 1529 women, I2 = 33%, moderate-quality evidence) and ovulation (OR 1.57, 95% CI 1.28 to 1.92, 21 studies, 1624 women, I2 = 64%, moderate-quality evidence). There was a statistically significant difference in miscarriage rate per woman, with higher rates in the combined therapy group (OR 1.59, 95% CI 1.03 to 2.46, 9 studies, 1096 women, I2 = 0%, low-quality evidence) but this is of uncertain clinical significance due to low-quality evidence, and no clear difference between groups when we analysed miscarriage per pregnancy (OR 1.30, 95% CI 0.80 to 2.12, 8 studies; 400 pregnancies, I2 = 0%, low-quality evidence). Metformin versus clomiphene citrateWhen all studies were combined, findings for live birth were inconclusive and inconsistent (OR 0.71, 95% CI 0.49 to 1.01, 5 studies, 741 women, I2 = 86%, very low-quality evidence). In subgroup analysis by obesity status, obese women had a lower birth rate in the metformin group (OR 0.30, 95% CI 0.17 to 0.52, 2 studies, 500 women, I2 = 0%, very low-quality evidence), while data from the non-obese group showed a possible benefit from metformin, with high heterogeneity (OR 1.71, 95% CI 1.00 to 2.94, 3 studies, 241 women, I2 = 78%, very low-quality evidence). Similarly, among obese women taking metformin there were lower rates of clinical pregnancy (OR 0.34, 95% CI 0.21 to 0.55, 2 studies, 500 women, I2 = 0%, very low-quality evidence) and ovulation (OR 0.29, 95% CI 0.20 to 0.43 2 studies, 500 women, I2 = 0%, low-quality evidence) while among non-obese women, the metformin group had more pregnancies (OR 1.56, 95% CI 1.05 to 2.33, 5 studies, 490 women, I2 = 41%, very low-quality evidence) and no clear difference in ovulation rates (OR 0.81, 95% CI 0.51 to 1.28, 4 studies, 312 women, low-quality evidence, I2=0%). There was no clear evidence of a difference in miscarriage rates (overall: OR 0.92, 95% CI 0.50 to 1.67, 5 studies, 741 women, I2 = 52%, very low-quality evidence). D-chiro-inositol (2 studies), rosiglitazone (1 study) or pioglitazone (1 study) versus placebo or no treatmentWe were unable to draw conclusions regarding other insulin-sensitising drugs as no studies reported primary outcomes. AUTHORS' CONCLUSIONS Our updated review suggests that metformin alone may be beneficial over placebo for live birth, although the evidence quality was low. When metformin was compared with clomiphene citrate, data for live birth were inconclusive, and our findings were limited by lack of evidence. Results differed by body mass index (BMI), emphasising the importance of stratifying results by BMI. An improvement in clinical pregnancy and ovulation suggests that clomiphene citrate remains preferable to metformin for ovulation induction in obese women with PCOS.An improved clinical pregnancy and ovulation rate with metformin and clomiphene citrate versus clomiphene citrate alone suggests that combined therapy may be useful although we do not know whether this translates into increased live births. Women taking metformin alone or with combined therapy should be advised that there is no evidence of increased miscarriages, but gastrointestinal side effects are more likely.

Evaluation of Relationship between Body Mass Index with Vitamin D Receptor Gene Expression and Vitamin D Levels of Follicular Fluid in Overweight Patients with Polycystic Ovary Syndrome. INTERNATIONAL JOURNAL OF FERTILITY & STERILITY 2017; 11:105-111. [PMID: 28670428 PMCID: PMC5347447 DOI: 10.22074/ijfs.2017.4704] [Citation(s) in RCA: 5] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 02/12/2016] [Accepted: 08/27/2016] [Indexed: 11/04/2022]
Abstract
BACKGROUND Polycystic ovary syndrome (PCOS) is the most common endocrine disorder associated with reproductive disorders and metabolic dysfunctions including insulin resistance. The roles of vitamin D in the regulation of metabolic modulations specifically involving insulin and reproduction processing are introduced. In addition, obesity appears to be closely associated with severity of PCOS. The present study is to evaluate the effect of body mass index (BMI) on vitamin D levels in follicular fluid and vitamin D receptor (VDR) expression levels in granulos cells. MATERIALS AND METHODS A comparative study was conducted on 80 women with average age of 20-35 years referred for in vitro fertilization (IVF). Patients were divided into four groups, and serum levels of testosterone and insulin resistance (IR) were evaluated at the puncture time. Also, vitamin D levels of follicular fluid were evaluated. VDR gene expression was assayed by quantified-polymerase chain reaction (PCR) technique. Correlations were evaluated with calculation of the Spearman coefficient, and also independent relationships were assessed by means of multiple regression analysis. RESULTS Vitamin D levels of follicular fluid decreased in PCOS patients compared with non-PCOS. Also, over-weight individuals had lower vitamin D levels compared with normal-weight patients. Vitamin D levels of follicular fluid were highly correlated with BMI (r=-0.51, P<0.01). Homeostatic model assessment-IR (HOMA-IR) values were significantly higher in women of PCOS/overweight and PCOS/normal weight in comparison with women of non-PCOS/normal weight (P<0.01). The gene expression data of VDR in granulosa cells were significantly lower in the PCOS/overweight group compared with the non-PCOS/normal weight (P<0.01). CONCLUSION The findings indicated significant differences in VDR gene expression in granulosa cells and vitamin D of follicular fluid in PCOS/overweight patients.

Abstract
Backgriond Polycystic ovary syndrome (PCOS) is a complex disease that has both genetic and environmental components. Adiponectin plays an important role in the regulation of insulin sensitivity and insulin resistance (IR) in PCOS. The aim of this study was to determine 2 single-nucleotide polymorphisms (SNPs) variants (rs12495941 and rs17300539) of the adiponectin gene (ADIPOQ) in polycystic ovary syndrome (PCOS) families. Material/Methods We recruited 197 PCOS probands, their biological parents, and 192 controls. Anthropometric variables, including hip circumference (HC) and waist circumference (WC), were measured in all subjects during their first visit to the outpatient department. Serum T, FBG, FINS, TC, TG, LDL, and HDL levels were measured. PCOS patients were divided into 2 groups based on BMI: group A (BMI <25 kg/m2) and group B (BMI ≥25 kg/m2). Parents of PCOS were accordingly categorized into group C and group D (fathers), and group E and group F (mothers). The associations among ADIPOQ rs12495941, rs17300539, and PCOS were analyzed using the transmission disequilibrium test (TDT). Results A significant association was found between SNP rs17300539 and PCOS in our Chinese population. The levels of TG and FINS and the genotype frequencies of rs17300539 are significantly different between overweight and lean PCOS. No significant association was detected for rs12495941. Conclusions TDT confirms that rs17300539 of ADIPOQ is strongly associated with the risk of PCOS in a Chinese Han population, but rs12495941 of ADIPOQ is not associated with the occurrence of PCOS.

Abstract
The aim of this study was to utilize various insulin resistance measuring methods to determine whether insulin resistance and other parameters impact the serum lipid levels of polycystic ovary syndrome (PCOS) patients and how the serum lipid levels in these patients are affected by the body mass index (BMI). Our dataset included patients between the ages of 16 and 42 (N = 228) from the outpatient endocrinology clinic of the Department of Obstetrics and Gynecology, who demonstrated increased hair growth and bleeding disorders and came for a routine oral glucose tolerance test (OGTT). Differences in the serum lipid levels were evaluated by t-test and linear regression analysis after adjusting for BMI. A stepwise regression model was constructed to evaluate the influence of each variable on the lipid levels. In PCOS patients, we found that dyslipidemia is more prevalent among hyperinsulinemic women compared with normoinsulinemic women, even after normalizing for BMI. PCOS patients with insulin resistance, determined by the insulin sensitivity index (ISI) method, showed more significant lipid abnormalities such as low high-density lipoprotein (HDL) and apo-A levels and high total cholesterol, low-density lipoprotein (LDL) and apo-B levels than if insulin resistance (IR) determination was based on insulin level or homeostatic model assessment (HOMA).

Abstract
This cross-sectional study aimed to investigate the association between menstrual cycle lenght and metabolic parameters in non-hyperandrogenic women with polycystic ovarian morphology, n = 250. Metabolic profiles of all participants were evaluated using anthropometric parameters (body mass index, waist circumference), parameters of dyslipidemia (total cholesterol, HDL-cholesterol, triglycerides) and markers of insulin resistance (fasting insulin, homeostasis model assessment for insulin resistance index). The associations between menstrual cycle lenght and cardiometabolic risk factors such as insulin resistance, dyslipidemia, and obesity were investigated. In non-hyperandrogenic women with polycystic ovarian morphology, menstrual cycle lenght was associated with hypertriglyceridemia and insulin resistance independently of body mass index. Moreover, menstrual cycle lenght added value to body mass index in predicting hypertriglyceridemia. The optimal menstrual cycle lenght cut-off value for identifying of non-hyperandrogenic women with polycystic ovarian morphology at metabolic risk was found to be 45 days. Metabolic profile of non-hyperandrogenic women with polycystic ovarian morphology (n = 75) with menstrual cycle lenght >45 days was similar to that of hyperandrogenic women with polycystic ovarian morphology (n = 138) while metabolic profile of non-hyperandrogenic women with polycystic ovarian morphology with menstrual cycle lenght ≤45 days (n = 112) was similar to that of controls (n = 167). Non-hyperandrogenic women with polycystic ovarian morphology with menstrual cycle lenght >45 days had higher prevalence of cardiometabolic risk factors compared to those with menstrual cycle lenght ≤45 days. Non-hyperandrogenic women with polycystic ovarian morphology are not metabolically homogeneous. Menstrual cycle lenght is an easy-to-obtain clinical parameter positively associated with the probability of unfavorable metabolic status in non-hyperandrogenic women with polycystic ovarian morphology. Menstrual cycle lenght cut-off value of 45 days was found to have the best capacity in discriminating non-hyperandrogenic women with polycystic ovarian morphology with and without metabolic derangement(s) corroborating in favor of the cardiometabolic risk factors screening and management in non-hyperandrogenic women with polycystic ovarian morphology with menstrual cycle lenght >45 days through strategies for prevention of cardiovascular disease.

Abstract
PURPOSE In this study, we aimed to investigate serum and follicular fluid amyloid A protein levels in non-obese non-hyperandrogenic patients with polycystic ovary syndrome (PCOS) undergoing in vitro fertilization (IVF) and IVF outcome. METHODS A total of 81 patients undergoing IVF treatment, 41 patients diagnosed as PCOS according to the Rotterdam criteria (group I) and 40 patients with the etiology of male factor infertility (group II), were included in the study. On the day of oocyte pickup, serum and follicular fluid samples were collected from all patients. RESULTS Serum E2 level on the day of hCG (2849.93 ± 541.54 vs. 2494.28 ± 712.98) and total number of retrieved oocytes (13.73 ± 3.57 vs. 10.53 ± 4.07) were significantly higher in group I when compared to group II (p < 0.05). However, number of mature oocytes, fertilization rate, and clinical pregnancy rate did not differ (p > 0.05). No significant difference was found between two groups regarding the serum and follicular fluid amyloid A protein levels on the day of oocyte retrieval (p > 0.05).

Abstract
Objective Insulin resistance is a common feature of polycystic ovary syndrome (PCOS). The insulin signaling pathway consists of two major pathways, the metabolic and the mitogenic cascades. The many components of these pathways have not been comprehensively analyzed for differential expression in insulin-responsive tissues in PCOS. The goal of this study was to determine whether the core elements of the insulin signal transduction cascade were differentially expressed in subcutaneous adipose tissue (SAT) between PCOS and controls. Materials/methods Quantitative real-time PCR for 36 insulin signaling pathway genes was performed in subcutaneous adipose tissue from 22 white PCOS and 13 healthy controls. Results Genes in the insulin signaling pathway were not differentially expressed in subcutaneous adipose tissue between PCOS and controls (P > 0.05 for all). Components mainly of the mitogenic pathway were correlated with both androgens and metabolic phenotypes. Expression levels of five genes (MKNK1, HRAS, NRAS, KRAS, and GSK3A) were positively correlated with total testosterone level (ρ > 0, P < 0.05). Inverse correlation was found between expression of six genes (HRAS, MAP2K2, NRAS, MAPK3, GRB2, and SHC1) and metabolic traits (body mass index, fasting glucose, fasting insulin, and HOMA-IR) (ρ < 0, P < 0.05). Conclusions Differential expression of core insulin signaling pathway components in subcutaneous adipose tissue is not a major contributor to the pathogenesis of PCOS. Correlation between clinical phenotypes and expression of several genes in the mitogenic limb of the insulin signaling pathway suggests mitogenic signaling by insulin may regulate steroidogenesis and glucose homeostasis. We examined gene expression in adipose tissue between PCOS and controls. Complete coverage of core elements of the insulin signaling pathway. Differential mRNA expression in adipose tissue is not a major contributor to PCOS. We discovered associations between mitogenic signaling components and phenotypes.

Abstract
Metformin has a potential role for insulin resistance in polycystic ovary syndrome(PCOS) and has demonstrated efficacy in diabetes. There are a large number of studies and evidence syntheses comparing metformin with control, lifestyle interventions, the oral contraceptive pill, and clomiphene citrate; however, there is still uncertainty about the effectiveness of metformin in women with PCOS. Here we present a systematic overview of the evidence for the use of metformin in women with PCOS. The evidence suggests that metformin continues to have an unclear roll in PCOS until further well designed; methodologically rigorous effectiveness studies with large sample sizes are conducted, and these should include women across the body mass index (BMI) range.

Albu A, Radian S, Fica S, Barbu CG. Biochemical hyperandrogenism is associated with metabolic syndrome independently of adiposity and insulin resistance in Romanian polycystic ovary syndrome patients. Endocrine 2015; 48:696-704. [PMID: 25022659 DOI: 10.1007/s12020-014-0340-9] [Citation(s) in RCA: 15] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/23/2013] [Accepted: 06/12/2014] [Indexed: 01/18/2023]
Abstract
The aim of the study was to determine whether Romanian polycystic ovary syndrome (PCOS) patients have an increased prevalence of metabolic syndrome (MetS) and to study the involvement of adiposity, insulin resistance and hyperandrogenism in the pathogenesis of MetS in PCOS. A total of 398 PCOS patients and 126 controls were evaluated between January 2006 and December 2012. MetS was defined by National Cholesterol Education Program, Adult Treatment Panel III criteria. Principal component analysis (PCA) was used to analyze the correlations among variables of interest by grouping them in few components, and principal component (PCs) scores were saved and used as independent variables in logistic regression. The prevalence of MetS was higher among patients with PCOS (20.4 %) than in controls (11.1 %, p < 0.05). In PCOS patients, PCA extracted three PCs from the analyzed variables. First PC aggregated variables related to adiposity and insulin resistance, with factor loadings showing strong relationship between these parameters. The second PC included markers of hyperandrogenemia and was best represented by free androgen index (FAI) which correlated strongly and exclusively with this PC. The third component was best represented by hirsutism. Logistic regression analysis revealed that in PCOS patients, the first and the second PCs were independently associated with MetS, whereas the third component was not. Romanian PCOS patients have an increased risk for MetS; adiposity, insulin resistance and hyperandrogenemia, but not hirsutism, are independent predictors of MetS presence. Our data also suggest that insulin resistance is only secondary to increased adiposity and FAI is a good marker of biochemical hyperandrogenism with little influences from the metabolic component.

Clinical and Biochemical Profiles according to Homeostasis Model Assessment-insulin Resistance (HOMA-IR) in Korean Women with Polycystic Ovary Syndrome. J Menopausal Med 2014; 20:104-10. [PMID: 25580421 PMCID: PMC4286654 DOI: 10.6118/jmm.2014.20.3.104] [Citation(s) in RCA: 8] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/20/2014] [Revised: 11/26/2014] [Accepted: 11/28/2014] [Indexed: 01/21/2023] Open
Abstract
Objectives The aim of this study was to investigate the clinical and biochemical profiles according to homeostasis model assessment of insulin resistance (HOMA-IR) in Korean polycystic ovary syndrome (PCOS) patients. Methods In 458 PCOS patients diagnosed by the Rotterdam European Society for Human Reproduction and Embryology (ESHRE) criteria, measurements of somatometry, blood test of hormones, glucose metabolic and lipid profiles, and transvaginal or transrectal ultrasonogram were carried out. HOMA-IR was then calculated and compared with the clinical and biochemical profiles related to PCOS. The patients were divided into 4 groups by quartiles of HOMA-IR. Results The mean level of HOMA-IR was 2.18 ± 1.73. Among the four groups separated according to HOMA-IR, body weight, body mass index (BMI), waist-to-hip ratio (WHR), triglyceride (TG), total cholesterol, high-density lipoprotein (HDL) cholesterol, low-density lipoprotein (LDL) cholesterol, lipid accumulation product (LAP) index, high-sensitivity C-reactive protein (hs-CRP), Apoprotein B, free testosterone, and sex hormone binding globulin (SHBG) were found to be significantly different. TG, LAP index, glucose metabolic profiles, and hs-CRP were positively correlated with HOMA-IR after adjustment for BMI. Conclusion Our results suggest that the clinical and biochemical profiles which are applicable as cardiovascular risk factors are highly correlated with HOMA-IR in Korean women with PCOS.

Abstract
Polycystic ovary syndrome is recognized as the most common hormonal and metabolic disorder of women. This heterogeneous endocrinopathy characterized by clinical and/or biochemical hyperandrogenism, oligo- or amenorrhoea, anovulatory infertility, and polycystic ovarian morphology. The prevalence, clinical feature and the risk of co-morbidity vary depending on the accuracy of the diagnosis and the criteria used. Evidence suggests that those women are at high risk who fulfil the criteria based on National Institute of Health. The complex feature of the syndrome and the considerable practice heterogenity that is present with regards to diagnostic testing of patients who are suspected to have polycystic ovary syndrome require an interdisciplinary, evidence-based diagnostic approach. Such a method can ensure the patient safety and the effectiveness and efficiency of the diagnosis. This paper summarises the highest available evidence provided by well-designed studies, meta-analysis and systematic reviews of the clinical feature and the clinical implications of the diagnostic criteria of polycystic ovary syndrome. Orv. Hetil., 2014, 155(30), 1175–1188.
