The Impact

The roles of dietary macronutrients and physical activity (PA) in patients with PCOS have not been sufficiently reported, especially in adolescent girls. To address this knowledge gap, we evaluated the associations between serum concentrations of total testosterone (tT), free testosterone (fT), androstenedione (A), dehydroepiandrosterone-sulfate (DHEA-S), sex hormone-binding globulin (SHBG) and dietary macronutrients intake as well as different types and levels of PA. The study population consisted of 96 girls of Caucasian ancestry, aged 14–18 years: 61 participants with polycystic ovary syndrome (PCOS) and 35 healthy controls. Serum tT, fT, A, DHEA-S, and SHBG were determined in fasting blood. Macronutrient intake and PA levels were assessed by using the three-day food record method and the Beliefs and Eating Habits Questionnaire (KomPAN), respectively. We found several positive correlations between dietary macronutrients such as total fat, saturated fatty acids (SFA), monounsaturated (MUFA) and polyunsaturated fatty acids (PUFA), and hormonal parameters across the entire cohort and in healthy girls. A positive correlation between SHBG and total protein consumption as well as an inverse correlation between SHBG and carbohydrate intake could be determined. No correlation between androgens and macronutrients was found in the PCOS group. In contrast, we observed an inverse correlation between androgen concentrations (except of DHEA-S) and “work/school” and/or “leisure time” PA only in PCOS patients. Moreover, the hormone levels differed according to PA intensity. In conclusion, the impact of diet and PA was strikingly different in adolescents with and without PCOS. These findings indicate that disturbed hormonal homeostasis in PCOS, at least in the youngest patients, likely “overtrump” dietary influences, and otherwise, PA offers a therapeutic potential that requires further evaluation of the long-term effects in randomized studies.

BACKGROUND: Polycystic ovary syndrome (PCOS), a common reproductive endocrinologic disorder in woman, was considered to be related to sleep disturbance. This study is aimed to analyze the correlation between excess androgen markers and Athens Insomnia Scale (AIS) in PCOS.METHODS: This observational, cross-sectional study of PCOS was conducted to 31 subjects to evaluate the correlation between serum total testosterone, sex hormone binding globulin (SHBG) and free androgen index with the incidence of sleep disturbance using AIS. Sleep disturbance was present if the score ≥6. The correlation between excess androgen markers and sleep disturbance was analyzed using Pearson’s coefficient of correlation or Spearman’s rho test. Correlation coefficient more than 0.5 with p<0.05 was considered significant.RESULTS: Out of 31 PCOS subjects aged 20-40 years, 39% subjects had AIS score ≥6. Mean serum testosterone in AIS score >6 group was higher than AIS score <6 group but not statistically significant (46.68 vs. 28.49 ng/mL, p>0.05). No significant correlation was found between serum total testosterone, SHBG and free androgen index with AIS score. After adjusting for AIS score, there was the moderate positive correlation between serum total testosterone level although not statistically significant (r=0.54, p=0.07).CONCLUSION: The serum total testosterone level might influence the occurrence of sleep disturbance in PCOS.KEYWORDS: PCOS, androgen excess, testosterone, sleep disturbance, Athens Insomnia Scale

Objective: We aimed to assess possible genomic instability in women with polycystic ovary syndrome (PCOS). Design: The frequency of micronuclei in cultured peripheral lymphocytes was used as a biomarker of genomic instability in somatic cells. Methods: Nineteen women, diagnosed with PCOS and 19 healthy female volunteers of corresponding ages and body-mass index (BMI) were included in the study. Micronuclei frequencies were assessed in cytokinesis-blocked lymphocytes. Results: The frequency of micronucleated cells (per thousand) was 9.00 (5.00) (interquartile range in parentheses) for patient group and 3.0 (3.0) for the control group (P < 0.0001, Mann-Whitney U-test). The serum levels of follicle-stimulating hormone (FSH), estradiol, prolactin, glucose and dehydroepiandrosterone sulfate (DHEAS) and the homeostasis model of assessment of insulin resistance (HOMA-IR) were not different between the two groups (P > 0.05). Serum total testosterone, luteinizing hormone (LH) and insulin levels and hirsutism score in the PCOS group were significantly (P = 0.007, P < 0.0001, P = 0.009 and P < 0.0001 respectively) higher than those of the control group (2.3 (2.1) nmol/l vs 1.7 (0.4) nmol/l; 8.5 (5.88) mU/ml vs 4.8 (4.4) mU/ml; 6.8 (5.1) μU/ml vs 9.7 (4.2) μU/ml; 19.5 (6.5) vs 4.0 (2.5) respectively). However, the mean level of sex hormone-binding globulin (SHBG) in PCOS group was significantly (P = 0.004) lower than in control group (36.4(22.6) nmol/l vs 48.6(25.2) nmol/l respectively). Conclusion: These findings suggest that women with PCOS have a high incidence of genomic instability, and this condition is positively correlated with the hirsutism score, BMI, LH and serum total testosterone and insulin levels, and is negatively correlated with SHBG.

Ovary Syndrome

ObjectiveExperimental evidence suggests that fetal exposure to androgen excess may program the development of polycystic ovary syndrome (PCOS) in utero. The aim of this study was to examine whether the sex hormone binding globulin (SHBG)(TAAAA)n and the cytochrome P450, family 19 (CYP19)(TTTA)n polymorphisms, known to influence sex hormone-binding globulin (SHBG) levels and aromatase activity respectively, play a synergistic role in the development of PCOS.Design and methodsWe studied 180 women with PCOS and 160 healthy women of reproductive age. The body mass index (BMI) was recorded and the hormonal profile determined from the third to fifth day of menstrual cycle. DNA was extracted from blood leucocytes and the SHBG(TAAAA)n and CYP19(TTTA)n polymorphisms were genotyped.ResultsGenotype analysis revealed 6 SHBG(TAAAA)n alleles with 6–11 repeats and 6 CYP19(TTTA)n alleles with 7–12 repeats. Women were subdivided into four groups: those with short SHBG (≤8 TAAAA repeats) and CYP19 alleles (≤9 TTTA repeats), those with short SHBG–long CYP19 alleles, those with long SHBG–short CYP19 alleles, and those with long SHBG and CYP19 alleles. Women with PCOS tended to have at greater frequency, long SHBG–short CYP19 alleles compared with controls (57.3 vs 42.4%, P=0.07). Importantly, PCOS women with long SHBG–short CYP19 alleles had the lowest SHBG levels (P=0.02) and the highest total testosterone (P=0.008), free androgen index (P=0.002), DHEAS (P=0.02), and testosterone/estradiol ratio (P=0.03), compared with those with other genotypes. This association was independent of age, BMI, and insulin resistance indexes.ConclusionWe speculate that the SHBG and CYP19 genes may have a synergistic role in the developmental programming of PCOS, by affecting androgen bioavailability and aromatization respectively.

The role of inappropriate lifestyle in the etiology of polycystic ovary syndrome (PCOS) and its metabolic and reproductive complications has attracted much attention in recent years; however, most studies involve adult patients. Thus, the study aimed to compare dietary patterns, physical activity, metabolic, anthropometric and inflammatory markers of 14–18-year-old girls with and without PCOS (n = 61 and n = 35, respectively) as well as to assess correlations between concentrations of metabolic and inflammatory markers and macronutrient intake and to identify the independent predictors of PCOS, related to diet and physical activity (PA). Compared to the control group, PCOS girls consumed significantly more total fat (p = 0.0005), including both saturated (SFA) (p = 0.03), monounsaturated (MUFA) (p = 0.0003) and polyunsaturated fatty acids (PUFA) (p = 0.01). A significantly higher percentage of PCOS patients consumed high and medium glycemic index (GI) foods (p = 0.03) and represented a low level of PA, both during school and in leisure time (41.67 vs. 6.06%; p = 0.0001 and 32.79 vs. 5.71%; p = 0.003, respectively). The PCOS group had also significantly higher waist circumference (WC), C-reactive protein (CRP) (p = 0.01), LDL cholesterol (p = 0.01), fasting insulin (p = 0.002) and HOMA-IR (p = 0.006) levels. There was an inverse correlation between fiber intake and fasting insulin, (p = 0.0002, r = −0.37), HOMA-IR (p = 0.0004, r = −0.35), WC (p = 0.029; r = −0.222) and a positive relationship between high and medium GI diet and insulin concentration (p = 0.003; r = 0.3). An increase of 10 g/day in total fat intake per day increases the probability of PCOS by 1.4 times. If the SFA or MUFA intakes increase by 10 g, the probability of PCOS increase 1.7-fold and 2.5-fold, respectively. The consumption of foods with a medium GI raises the probability of PCOS by more than 3 times, after adjusting for age. The odds ratio decreased for the moderate and high PA at school/work and in leisure time. Further research in girls with PCOS is needed to test whether low GI and dietary fatty acid reduction combined with increased PA is effective in the nonpharmacological treatment and prevention of PCOS complications.

ObjectiveMuscle mass plays an important role in determining cardiovascular and metabolic risks in polycystic ovary syndrome (PCOS). In addition, whether lean mass influences carotid intima-media thickness (IMT) in PCOS has not been assessed.DesignProspective investigation.MethodsNinety-five women with PCOS were age- and weight-matched to 90 ovulatory controls. All women had dual X-ray absorptiometry for lean, fat and bone mass, and bone mass density (BMD). Serum testosterone, sex hormone-binding globulin, insulin, and glucose and carotid IMT were determined. Free androgen index (FAI) and insulin resistance (by QUICKI) were calculated.ResultsIn PCOS, waist circumference and insulin were higher and QUICKI lower than in controls (P<0.01). Trunk fat mass, % trunk fat, and lean mass were higher in PCOS compared to controls (P<0.01), while total bone mass and BMD were similar. IMT was increased in PCOS (P<0.01) but only 15% of PCOS patients had abnormal (≥0.9 mm) values. Lean mass correlated with fat parameters, insulin, QUICKI, and FAI, but not with total testosterone; and after adjustments for insulin and QUICKI, lean mass still correlated with fat mass (P<0.01) but not FAI. Lean mass correlated with IMT (P<0.01), but this was dependent on insulin. However, excluding those patients with abnormal IMT values, IMT correlated with lean mass independently of insulin. Bone mass correlated with lean and fat mass, but not with insulin or androgen. PCOS patients with ‘pathological’ IMT values had higher % trunk fat, lean mass, and insulin, lower QUICKI, and higher testosterone and FAI compared with those with normal IMT.ConclusionLean mass is increased in PCOS, while bone mass is similar to that of matched controls. The major correlates of lean mass are fat mass and insulin but not androgen. Lean mass also correlated with IMT, and although influenced by insulin, small changes in IMT may partially reflect changes in muscle mass, while clearly abnormal values relate to more severe abnormalities of PCOS.

Background: Polycystic ovary syndrome (PCOS) increases the risk of metabolic syndrome (MetS). Insulin resistance (IR) plays a major role in the pathophysiology of both PCOS and MetS. Objective: This study was designed to compare the prevalence of MetS among different phenotypes of PCOS and its relationship with androgenic components. Materials and Methods: 182 participants eligible for this five-group comparative study were selected by convenience sampling method. They were classified according to the Rotterdam criteria: clinical and/or biochemical hyperandrogenism (H) + PCOS on ultrasound (P) + ovulation disorders (O) (n = 41), clinical and/or biochemical H + PCOS on P (n = 33), PCOS on P + O (n = 40), clinical and/or biochemical H + O (n = 37), and control (without PCOS) (n = 31). MetS was measured based on the National Cholesterol Education Program Adult Treatment Panel III criteria. Androgenic components included free androgen- index (FAI), total-testosterone (TT) level and sex-hormone-binding-globulin (SHBG). Results: A significant difference was observed between the study groups in terms of MetS prevalence (p = 0.01). In phenotype H+P+O, there was a statistically significant positive association between TG and TT, and a significant negative association between SBP and DBP with SHBG. In phenotype O+P, WC was inversely associated with SHBG. In phenotype H+O, FBS and TG were positively associated with FAI but HDL was inversely associated with FAI. Moreover, WC and DBP were positively associated with TT in phenotype H+O. No associations were detected between MetS parameters and androgenic components in other PCOS subjects (phenotype H+P) and in the control group. TT was significantly higher in the PCOS group suffering from MetS (p = 0.04). Conclusion: According to the research results, hyperandrogenic components are potent predictors of metabolic disorders. Thus, we suggest that MetS screening is required for the prevention of MetS and its related complications in PCOS women. Key words: Polycystic ovary syndrome, Metabolic syndrome, Hyperandrogenism.

AbstractTo investigate sexual function in Chinese women with polycystic ovary syndrome (PCOS) and to explore the correlation with clinical and biochemical characteristics. A cross-sectional study was designed in 1000 PCOS women, aged 18–45 years, via the Chinese version of Female Sexual Function Index (FSFI) evaluating sexual function, with additional questions possibly related to sexual life. Clinical and biochemical characteristics likely to affect sexual function were determined, including anthropometric indicators, serum levels of hormones, luteinizing hormone to follicle-stimulating hormone ratio (LH/FSH ratio), prolactin (PRL), total testosterone (TT), free androgen index (FAI), sex-hormone-binding globulin (SHBG), glucose, and lipid metabolism indicators. Nine hundred ten PCOS women participated in the study, 685 patients were included after screening, and 211 were suitable to detect correlations of clinical and biochemical characteristics with sex function parameters. The mean total FSFI score was 24.19 ± 2.8; 79.56% of the women were at risk of female sexual dysfunction (FSD). Women doing regular aerobic exercise and use of contraception had higher FSFI scores, while those with a desire to conceive and clinical signs of hyperandrogenism had lower FSFI scores. There were negative associations of FSFI scores with age and body fat distribution. No significant associations between FSFI scores and hormonal factors (surprisingly including SHBG) were found, except for total testosterone and satisfaction (OR = 0.976, p = 0.002). HOMA-IR was significantly related to reduced desire score (OR = 0.914, p = 0.004) and lubrication score (OR = 0.964, p = 0.044). PCOS was associated with a high risk of FSD (defined according to FSFI) in about 80% of the women in our study, and clinical characteristics play a more important role.

ObjectiveTo assess whetherTCF7L2single nucleotide polymorphisms rs7903146 C/T and rs11196236 C/T are associated with polycystic ovary syndrome (PCOS) in South Brazilian women.DesignCross-sectional study.MethodsTwo hundred PCOS patients and 102 non-hirsute, ovulatory controls were genotyped by real-time PCR. Haplotypes were constructed from the combination of both polymorphisms. Frequencies were inferred using the PHASE 2.1.1 software.Results and conclusionsThe distribution of rs7903146 (PCOS, 54.4% CC; 28.5% CT; 17.1% TT; controls, 51.0% CC; 37.0% CT; 12.0% TT) and rs11196236 (PCOS, 4.3% CC; 33.5% CT; 62.2% TT; controls, 3.2% CC; 35.5% CT; 61.3% TT) was similar between the groups. rs7903146 and rs11196236 were not in linkage disequilibrium (|D′|=0.34;r2=0.07). PCOS participants were younger, with higher age-adjusted BMI, waist circumference, blood pressure, triglycerides, insulin, homeostasis model assessment index to estimate insulin resistance and total testosterone, and lower HDL-C and sex hormone binding globulin vs controls. In PCOS, no differences between genotypes and haplotypes were found for clinical and metabolic variables. However, for each T (rs7903146) and T (rs11196236) allele added to the haplotypes, a variation of 5.87 cm in waist (Ptrend=0.01), 10.7 mg/dl in total cholesterol (Ptrend=0.03), and 10.3 mg/dl in LDL-C (Ptrend=0.01) was recorded.TCF7L2variants are probably not implicated in PCOS development in South Brazilian women.
