ABSTRACT

Abstract Objective It has been suggested that excess body weight could represent a risk factor for infertility outcomes. The present study aimed to evaluate the association of overweight and anovulation among infertile women with regular menstrual cycles. Methods We conducted a retrospective case-control study with consistently anovulatory patients undergoing assisted reproduction treatment. The patients were stratified into normal weight (body mass index [BMI]: 18.5-24.9kg/m2) and overweight (BMI: 25.0- 29.9kg/m2).Those with polycystic ovary syndrome or obesity were excluded. The groups were matched for age, duration of infertility, prolactin, follicle stimulating hormone (FSH), thydroid stimulating hormone (TSH), luteinizing hormone (LH), and estradiol levels. Results Overweight was significantly associated with anovulation, when using the World Health Organization (WHO) criteria for anovulation: progesterone levels>5.65 ng/ml and ultrasonography evidence of follicle collapse (odds ratio [OR]: 2.69; 95% confidence interval [CI95%]: 1.04-6.98). Conclusion Body mass index above the normal range jeopardizes ovulation among non-obese infertile women with regular menstrual cycles.


Resumo Objetivo O excesso de peso corporal tem sido associado como fator de risco para infertilidade. Este estudo teve como objetivo avaliar a associação de sobrepeso e anovulação entre mulheres inférteis com ciclos menstruais regulares. Métodos Realizamos um estudo retrospectivo de caso-controle com mulheres com anovulação consistente em tratamento por reprodução assistida. As pacientes foram estratificadas entre aquelas com peso normal (índice de massa corporal [IMC]: 18,5- 24,9 Kg/m2) e as com sobrepeso (IMC: 25,0-29,9 Kg/m2). As pacientes com síndrome do ovário policístico ou obesidade foram excluídas. Os grupos foram pareados por idade, duração da infertilidade, níveis de prolactina, hormônio folículo-estimulante (FSH), hormônio tiroestimulante (TSH), hormônio luteinizante (LH) e estradiol. Resultados O excesso de peso associou-se significativamente à anovulaçãoquando usados os critérios de anovulação da Organização Mundial de Saúde (OMS): níveis de progesterona>5,65 ng/ml e evidência ultrassonográfica de colapso folicular (razão de chances [RC]: 2,69; IC95%: 1,04-6,98). Conclusão O IMC acima da faixa normal compromete a ovulação em mulheres inférteis não obesas com ciclos menstruais regulares.

ABSTRACT

A síndrome dos ovários policísticos (SOP) é uma condição endócrina frequente em mulheres em idade reprodutiva. O quadro clínico é manifesto por anovulação crônica hiperandrogênica, acompanhada muitas vezes de infertilidade; além disso, essa condição está associada ao aumento de distúrbios do metabolismo glicídico e a diversos outros riscos em longo prazo. Uma vez gestante, a mulher portadora de SOP apresenta risco aumentado em 2,8 vezes para o diabetes gestacional, em 2,0 a 4,0 vezes para o desenvolvimento de síndromes hipertensivas da gestação e em 2,3 vezes para internação em UTI neonatal. Independentemente do excesso de peso, que é comumente associado à síndrome e que certamente potencializa o risco de complicações, a SOP por si só promove alterações que cursam com a elevação dessas complicações. Esta é uma revisão narrativa sobre as potenciais complicações gestacionais relacionadas à SOP e compila a literatura mais atual sobre o tema.(AU)

ABSTRACT

ABSTRACT Objective: Galanin is a neuropeptide which has effects not only on metabolic syndrome but also on reproduction. Glypican-4 is an adipokine associated with insulin sensitivity by interacting directly with the insulin receptor. This study evaluated serum concentrations of galanin and glypican-4 in relation with the hormonal profile as well as metabolic and cardiovascular risk factors in patients with and without polycystic ovary syndrome (PCOS). Subjects and methods: A total of 44 women with PCOS and 44 age-matched controls were eligible. Hirsutism scores, hormonal profile, metabolic and cardiovascular risk factors as well as galanin and glypican-4 levels were evaluated in each subject. Results: Women with PCOS exhibited lower levels of galanin (20.2 pg/mL versus 26.4 pg/mL, p = 0.002) and higher concentrations of glypican-4 (3.1 ng/mL versus 2.6 ng/mL, p < 0.001) than controls. Both adipokines were correlated positively with body mass index (BMI), insulin, triglyceride and Homeostasis Model Assessment (HOMA) index; glypican-4 also showed positive correlations with fasting blood glucose, free testosterone, modified Ferriman-Gallwey scores (p < 0.05). Multiple Linear Regression analyses showed that PCOS and BMI were the best predictors affecting galanin levels with a decreasing and increasing effect respectively; however BMI was the best predictor affecting glypican-4 levels with an increasing effect (p < 0.001). Conclusion: Galanin levels were lower and glypican-4 levels were higher in women with PCOS than controls. Further studies are needed to determine whether these adipokines could be used as additional markers for insulin sensitivity and lipid profile and whether they might play a role in the pathogenesis of PCOS, in which metabolic cardiovascular risks are increased.

ABSTRACT

Resumo Fundamento: A síndrome dos ovários policísticos (SOP) é a doença endócrino-metabólica mais comum em mulheres em idade reprodutiva, e ocorre em uma a cada 10 mulheres. A doença inclui irregularidade menstrual e excesso de hormônios masculinos e é a causa mais comum de infertilidade em mulheres. A dispneia é um sintoma frequente e muitas vezes acredita-se que seja decorrente da obesidade, mas não se sabe se é decorrente de disfunção cardíaca. Objetivo: Avaliar o acoplamento ventrículo-arterial (VDAP) e a rigidez arterial pulmonar em pacientes com SOP. Métodos: Foram incluídos 44 pacientes com SOP e 60 controles; amostras de sangue venoso foram coletadas para exames laboratoriais e ecocardiograma transtorácico 2-D, Modo-M e com Doppler tecidual foram realizados em todos os participantes. Um valor de p<0,05 foi considerado estatisticamente significativo. Resultados: Quando comparadas ao grupo controle, as pacientes com SOP apresentaram valores maiores de rigidez da artéria pulmonar (p = 0,001), que se correlacionaram positivamente com o índice HOMA-IR (r = 0,545 e p <0,001). O acoplamento VDAP também estava comprometido em 34% dos pacientes do estudo. Conclusão: A rigidez da artéria pulmonar está aumentada e o acoplamento VDAP está comprometido em pacientes com SOP.

Abstract Background: Polycystic ovary syndrome (PCOS) is the most common endocrine-metabolic disease in women in reproductive age, and occurs in one of 10 women. The disease includes menstrual irregularity and excess of male hormones and is the most common cause of female infertility. Dyspnea is a frequent symptom and is often thought to be due to obesity, and whether it is due to cardiac dysfunction is unknown. Objective: To evaluate right ventricle-pulmonary artery (RV-PA) coupling and pulmonary arterial stiffness in patients with PCOS. Methods: 44 PCOS patients and 60 controls were included; venous blood samples were taken for laboratory tests and 2-D, m-mode and tissue doppler transthoracic echocardiography were performed for all the participants. P<0,05 was considered as statistically significant. Results: When compared to the control group, PCOS patients had higher pulmonary artery stiffness values (p=0,001), which were positively correlated with HOMA-IR (r=0,545 and p<0,001). RV-PA coupling was also impaired in 34% of the study patients. Conclusion: Pulmonary artery stiffness is increased and RV-PA coupling is impaired in patients with PCOS.

ABSTRACT

ABSTRACT Purpose Polycystic ovary syndrome (PCOS) is heterogenous condition with commonly associated symptoms include irregular menstrual cycle, hirsutism, baldness, adult acne, and weight gain There have been few attempts at profiling the voice characteristics of women with polycystic ovary syndrome. Videokymography enables to detect even subtle variations in vocal fold vibrations. The aim of the present study was to study the videokymographic characteristics among women with PCOS. Methods A cross-sectional study was carried out among 50 women with and without PCOS diagnosed on ultrasonography. Videokymography was carried out and the characteristics were perceptually analyzed using a vocal fold kymographic rating scale. The analysis of the kymogram was done for the following characteristics; presence of vocal fold vibration,interference of surroundings, Cycle to cycle variability, left-right asymmetry,cycle aberrations and shape of lateral peaks. The kymographic images were obtained for all the participants of both the groups and a subjective consensus evaluation was done by two clinicians. The percentage of participants with the listed kymographic characteristics were tabulated. Chi Square test was also done to decide if there was a significant difference between the two groups for different kymographic features of vocal fold vibration. Results Six of the 25 women with PCOS were found to have abnormal kymographic features such as surrounding structural interference, presence of cycle to cycle variability and the shape of lateral peaks. Conclusion Early detection of the vocal abnormalities in individuals with PCOS would help in the vocal rehabilitation especially for professional voice users.

ABSTRACT

SUMMARY There is no pooled information about pelvic floor parameters (muscle assessment, disorders) of women with gynecologicaL endocrinopathies (eg. polycystic ovary syndrome, congenital adrenal hyperplasia, premature ovarian insufficiency). Given that, a systematic review was performed on the Pubmed, Scopus, Google Scholar, Scielo and PEDro databases regarding the main gynecological endocrinopathies [polycystic ovary syndrome (PCOS), premature ovarian insufficiency (POI), congenital adrenal hyperplasia (CAH) and hyperprolactinemia (HPL)] since their inception to April 2020. Data quality assessment was made by the Newcastle-Ottawa Scale (NOS) adapted for cross-sectional studies. A total of 4,272 results were retrieved from all databases. After excluding duplicate results and screening by title and abstract, nine studies were selected for quantitative analysis. Seven studies were performed with women with PCOS and two studies with POI. Women with PCOS presented a higher prevalence of urinary incontinence (UI) among obese women, a higher thickness of the levator ani muscle, and higher levels of muscle activity measured by surface electromyograph when compared to the control women. Regarding POI, there was no association with UI, FI, and POP. NOS found that the quality assessment for these selected studies ranged from 5 to 8. We concluded that higher pelvic muscle activity and volume were found in women with PCOS, with further studies needed to confirm this data. Literature was scant about POI, CAH, and HPL.


RESUMO Existe informação não organizada sobre a avaliação do assoalho pélvico de mulheres com endocrinopatias ginecológicas (ex. síndrome dos ovários policísticos - SOP, hiperplasia adrenal congênita - HAC, insuficiência ovariana prematura - IOP). Dessa forma, objetivamos realizar uma revisão sistemática foi realizada nas bases Pubmed, Scopus, Google Scholar, Scielo e PEDro sobre as endocrinopatias ginecológicas (SOP, HAC, IOP e hiperprolactinemia (HPL) desde a origem a abril de 2020. A avaliação da qualidade de dados foi real-izada pela escala de Newcastle-Ottawa Scale (NOS) adaptada para estudos transversais. De 4,272 resultados encontrados em todas as databases, após exclusão por duplicatas, triando por título e resumos, nove estudos foram selecionados para análise quantitativa. Sete estudos foram realizados para mulheres com SOP e dois estudos com IOP. Em suma, mulheres com SOP apresentados uma alta prevalência de incontinência urinária (IU) em mulheres obesas, alta espessura do músculo elevador do ânus, altos níveis de atividade muscular aferida por eletromiografia de superfície quando comparadas com mulheres do grupo controle. Sobre a IOP, esta não foi associada com IU, IF e POP. A escala NOS evidenciou que a qualidade dos estudos selecionados variou de 5 a 8. Concluímos que uma alta atividade e volume muscular foi encontrada em mulheres com SOP, com estudos posteriores sendo necessários para confirmar estes achados. Literatura foi escassa para IOP, HAC e HPL.

ABSTRACT

ABSTRACT Objective Polycystic ovary syndrome (PCOS) is a recognized risk factor for nonalcoholic fatty liver disease (NAFLD). The aims of this study were to investigate the prevalence and factors associated with NAFLD in women with PCOS and evaluate noninvasive indices of hepatic fibrosis in patients with PCOS and NAFLD. Subjects and methods Patients with PCOS (n = 87) and women without PCOS (n = 40; controls) were included. NAFLD was diagnosed by abdominal ultrasonography after exclusion of alcohol consumption and viral or autoimmune liver disease. Anthropometric, clinical and metabolic variables, homeostasis model assessment of insulin resistance (HOMA-IR) index, lipid accumulation product (LAP), FIB-4 index, NAFLD score, and transient elastography (TE; FibroScan) were obtained in subsets of patients with PCOS and NAFLD. Results A total of 87 patients with PCOS were included (mean age: 34.4 ± 5.7 years, mean body mass index [BMI]: 34.7 ± 4.7 kg/m 2 ). NAFLD was present in 67 (77.0%) patients with PCOS versus 21 of 40 (52.5%) controls (p = 0.005). Women with PCOS and liver steatosis, compared with their NAFLD-free counterparts, had higher values of BMI, waist circumference, triglycerides, total cholesterol, alanine and aspartate aminotransferases, and γ-glutamyltransferase, along with higher frequencies of obesity, metabolic syndrome, and insulin resistance. NAFLD was independently associated with waist circumference, serum triglycerides, and alanine aminotransferase levels. The FIB-4 index was not compatible with advanced fibrosis in any of the evaluated patients, while NAFLD score and TE were compatible with advanced liver fibrosis in 1 of 26 (3.8%) and 3 of 25 (12%) patients, respectively. Conclusion Women with PCOS had a high risk of NAFLD, and a combination of both was associated with central obesity, dyslipidemia, insulin resistance, and metabolic syndrome. Noninvasive methods suggested low rates of severe hepatic fibrosis in Brazilian women with PCOS. Arch Endocrinol Metab. 2020;64(3):235-42

ABSTRACT

Abstract Objective The present study aimed to analyze cardiac autonomic modulation via spectral and symbolic analysis of heart rate variability (HRV) in women with polycystic ovary syndrome (PCOS) who were subjected to two consecutive tilt tests. Methods A total of 64 women were selected and divided into 2 groups: control (without PCOS), and PCOS. Concentrations of follicle-stimulating hormone, luteinizing hormone, prolactin, estradiol, homocysteine, sex hormone-binding globulin, thyroid stimulating hormone, fasting insulin, testosterone, androstenedione, and 17-hydroxyprogesterone levels, triglycerides, free androgen index (FAI), and homeostasis assessment model (HOMA-IR) were assessed. Cardiac autonomic modulation was evaluated by spectral and symbolic analyses during two consecutive tilt tests (two moments) and supine moments before, between and after (three moments) the tilt tests. Results Women with PCOS had higher fasting insulin, HOMA-IR indexes, testosterone and FAI. Additionally, we observed that the PCOS group had greater sympathetic autonomic cardiac modulation in supine 2, tilt 1, and supine 3 moments compared with controls. Conclusion Women with PCOS had higher autonomic sympathetic cardiac modulation even after a second tilt test. No adaptation to this provocative test was observed. Spectral analysis was more sensitive for identifying differences between groups than the symbolic analysis.


Resumo Objetivo O presente estudo teve como objetivo analisar a modulação autonômica cardíaca por análise espectral e simbólica da variabilidade da frequência cardíaca (VFC) em mulheres com síndrome dos ovários policísticos (SOP) que foram submetidas a dois testes consecutivos de inclinação. Métodos Um total de 64 mulheres foram selecionadas e divididas em 2 grupos: controle (sem SOP) e SOP. Concentrações de hormônio folículo-estimulante, hormônio luteinizante, prolactina, estradiol, homocisteína, globulina de ligação a hormônios sexuais, hormônio estimulante da tireóide, insulina em jejum, testosterona e androstenediona e níveis de 17-hidroxiprogesterona, triglicerídeos, índice de andrógeno livre (FAI) e homeostase modelo de avaliação (HOMA-IR) foram avaliados. A modulação autonômica cardíaca foi avaliada por análises espectrais e simbólicas durante dois testes de inclinação consecutivos (dois momentos) e momentos supinos antes, entre e após (três momentos) os testes de inclinação. Resultados Mulheres com SOP apresentaram insulina em jejuM, índices HOMA-IR, testosterona e FAI mais altos. Além disso, observamos que o grupo PCOS apresentou maior modulação cardíaca autonômica simpática nos momentos supino 2, inclinado 1 e supino 3 em comparação aos controles. Conclusão Mulheres com SOP apresentaram modulação cardíaca simpática autonômica mais alta mesmo após um segundo teste de inclinação. Nenhuma adaptação a esse teste provocativo foi observada. A análise espectral foi mais sensível para identificar diferenças entre os grupos do que a análise simbólica.

ABSTRACT

Abstract Objective To evaluate the prevalence of metabolic syndrome (MetS) in the phenotypes of polycystic ovarian syndrome (PCOS). Methods This was a cross-sectional study involving 111 women aged between 18 and 39 years old diagnosed with PCOS, according to the Rotterdam Criteria, and grouped into four phenotypes: A: ovulatory dysfunction + hyperandrogenism + polycystic ovaries; B: ovulatory dysfunction + hyperandrogenism; C: hyperandrogenism + polycystic ovaries; D: ovulatory dysfunction + polycystic ovaries. To evaluate the presence of MetS, wemeasured serum triglyceride levels, HDL cholesterol, fasting blood glucose, blood pressure, and waist circumference. Results The prevalence of MetS found in this sample was 33.6%, and there was no statistically significant difference (p < 0.05) among the 4 phenotypes. However, phenotype D presented a significantly higher mean glucose level after fasting (93.6 mg/dL) and 2 hours after ingesting a solution with 75 g of anhydrous glucose (120 mg/dL), as well as the lowest mean level of high-density lipoprotein (HDL) cholesterol (44.7 mg/dL). The women in this group demonstrated a high prevalence of abdominal circumference ≥ 80 cm (68.2%), as well as the highest mean abdominal circumference (90.1 cm). Amongst the women with an abdominal circumference ≥ 80 cm, phenotype A increased approximately six-fold the chance of developing metabolic syndrome in relation to phenotype C. Conclusion The four phenotypes of PCOS demonstrated similar prevalence rates of metabolic syndrome; abdominal obesity presented a relevant role in the development of metabolic alterations, regardless of the phenotype.


Resumo Objetivo Avaliar a prevalência da síndromemetabólica nos fenótipos da síndrome do ovário policístico. Métodos Trata-se deum estudo transversal envolvendo 111 mulheres comidade entre 18 e39 anos com diagnóstico de síndrome do ovário policístico, segundo os critérios de Roterdã, e agrupadas em quatro fenótipos: A: Disfunção ovulatória + hiperandrogenismo + ovários policísticos;B: disfunçãoovulatória + hiperandrogenismo; C: hiperandrogenismo + ovários policísticos; D: disfunção ovulatória + ovários policísticos. Para avaliar a presença de síndrome metabólica, foram medidos os níveis séricos de triglicérides, colesterol HDL e glicemia de jejum, pressão arterial e circunferência da cintura. Resultados A prevalência de síndrome metabólica encontrada nesta amostra foi de 33,6%, e não houve diferença estatisticamente significativa (p < 0,05) entre os quatro fenótipos. Entretanto, o fenótipo D apresentou um nível médio de glicose significativamente mais alto após o jejum (93,6 mg/dL) e duas horas após a ingestão de uma solução com 75g de glicose anidra (120 mg/dL), bem como o menor nível médio de colesterol HDL (44,7 mg/dl). As mulheres deste grupo demonstraram alta prevalência de circunferência abdominal ≥ 80 cm (68,2%), bem como a maior média de circunferência abdominal (90,1 cm). Entre as mulheres com circunferência abdominal ≥ 80 cm, o fenótipo A aumentou em aproximadamente 6 vezes a chance de desenvolver síndrome metabólica em relação ao fenótipo C. Conclusão Os quatro fenótipos da síndrome do ovário policístico demonstraram taxas semelhantes de prevalência de síndrome metabólica; a obesidade abdominal apresentou papel relevante no desenvolvimento de alterações metabólicas, independentemente do fenótipo.

ABSTRACT

Background: Patients with polycystic ovarian syndrome (PCOS) have an increased prevalence of metabolic syndrome and traditional atherosclerotic risk factors, such as dyslipidemia, diabetes and hypertension. Endothelial function and vascular stiffness are surrogate markers of early atherosclerosis, able to predict cardiovascular events. Objective: To compare endothelial function and pulse wave reflection between women with PCOS and healthy controls. Methods: Observational and cross-sectional study that included women with PCOS, age between 18 and 40 years-old and body mass index between 25.0 and 35.0 kg/m2, and healthy controls. Rotterdan criteria was used to diagnose PCOS. Subjects underwent clinical and anthropometric evaluation, laboratory and hormonal assays and imaging tests to measure pulse wave velocity (PWV), augmentation index (AIx) and brachial artery flow-mediated vasodilation (FMD). Kolmogorov-Smirnov test showed normal distribution of most parameters. Unpaired Student t-test was used with significance level established at p < 0.05.Results: A total of 52 patients were included, 29 (56%) in PCOS group and 23 (44%) in control group. Clinical and laboratory parameters were similar between the groups. Women with PCOS had lower FMD (8.8 ± 1.0 vs 12.8 ± 1.2%, p = 0.021); PWV and AIx were similar between the groups (7.5 ± 0.2 vs 7.5 ± 0.3 m/s, p = 0.671 and 21.0 ± 1 vs. 20 ± 2%, p = 0.716, respectively). In the PCOS group, women with higher testosterone levels had higher AIx (25 ± 2 vs. 17 ± 3%, p = 0.045). Conclusions: PCOS women had endothelial dysfunction and those with higher testosterone levels had higher pulse wave reflection as compared with controls

ABSTRACT

RESUMEN Diversos estudios bioquímicos adicionales a la evaluación de Testosterona total (TT), biodisponible (Tbio) y libre (TL) han sido realizados a los efectos que pudieran resultar de mayor utilidad para el diagnóstico de patologías concomitantes en el SOP, entre otros. En la hormona anti Mülleriana, cuando la concentración supera a los 3,0 ng/ml existen evidencias de que el 79% de las mismas pueden ser identificadas correctamente como SOP. El Antígeno Prostático Específico (PSA), marcador de singular importancia en pacientes con cáncer de Próstata, con técnicas ultrasensibles ha podido ser detectado en más del 50% en mujeres. En un grupo de pacientes con SOP, los niveles circulantes de PSA fueron significativamente mayores que en las mujeres sin SOP. El Kiss-1 aislado de la placenta y demostrado en otros tejidos, presenta niveles aumentados que correlacionan con la LH, TT, TL y resistencia a la insulina (RI) en adolescentes con SOP versus adolescentes sin SOP, sugiriendo que el Kiss-1 podría estar involucrado en el desarrollo del SOP en estas pacientes. Algunas pacientes con SOP están asociadas a patologías relevantes, de las cuales han sido comunicadas el aumento del BMI, mayor grado de dislipemia, adiposidad central, RI y Síndrome Metabólico (SMe). En las pacientes con un fenotipo clásico (hiperandrogenismo, alteración del ciclo menstrual y ovarios poliquísticos), estas patologías son de mayor frecuencia y severidad que en los otros fenotipos, particularmente aquellos sin hiperandrogenismo. Otras determinaciones como TNFα, interleuquinas, test de tolerancia a la glucosa, ApoB, partículas pequeñas de LDL e Inhibidor del Activador del Plasminógeno-1 han sido comunicados que podrían ser de utilidad para tener mayor sensibilidad en la definición de patología concomitantes en el SOP. Actualmente se ha comenzado a evaluar otros marcadores como el Fetuin-A; Quemerina, Nesfatina-1, Neopterina y Endocannabinoides, cuyos resultados preliminares parecerían ser un aporte importante para evaluar SMe y RI en paciente con SOP y tratar de definir su prevalencia en los distintos fenotipos de esta patología.


ABSTRACT Several biochemical studies in addition to the evaluation of total Testosterone (TT), bioavailable (bioT) and free (FT) have been performed to the effects that could be of greater use for the diagnosis of concomitant pathologies in the PCOS, among others. The anti-Müllerian hormone whose concentration when exceeds 3.0 ng/ml, there is evidence that 79% of these patients can be correctly identified as PCOS. The Prostate-Specific Antigen (PSA), a marker of singular importance in patients with prostate cancer, with ultra-sensitive techniques, has been detected in more than 50% of women. In a group of patients with PCOS, circulating levels of PSA are significantly higher than in women without PCOS. The Kiss-1 isolated from the placenta and demonstrated in other tissues, has increased levels that correlate with LH, TT, TL and insulin resistance (IR) in adolescents with PCOS respect to adolescents without PCOS, suggesting that Kiss-1 could be involved in the development of the PCOS in these patients. In some patients with PCOS, they are associated with relevant pathologies, of which the increase in BMI, higher degree of dyslipidemia, central adiposity, IR and Metabolic Syndrome (MeS) have been reported. Those that show a classic phenotype (hyperandrogenism, alteration of the menstrual cycle and polycystic ovaries) these characteristics are of greater frequency and severity than in the other phenotypes, particularly those without hyperandrogenism. Other determinations such as TNFα, interleukins, glucose tolerance test, ApoB, small particles of LDL and Plasminogen Activator Inhibitor-1 have been reported that could be useful to have greater sensitivity in the definition of concomitant pathology in the PCOS. Currently, other markers such as Fetuin-A, Chemerin, Nesfatin-1 Neopterin and Endocannabinoids have been evaluated. The preliminary results suggest to be an important contribution to define MeS and IR in patient with PCOS and to try to determine its prevalence in the different phenotypes of this pathology.

ABSTRACT

Abstract Objective To evaluate the effects of nutritional counseling on the dietary habits and anthropometric parameters of overweight and obese adolescentswith polycystic ovary syndrome (PCOS). Methods This was a prospective, longitudinal and auto-controlled study. Thirty adolescents aged 13-19 years-old, diagnosed with PCOS received nutritional counseling and were followed-up for 6 months. After the follow-up period, the results were evaluated through body weight, body mass index (BMI) and waist circumference (WC). Results Sixty-percent of the adolescents adhered to the nutritional counseling and, of these, 50% lost weight. Adolescents who lost weight changed their dietary habits by adopting hypocaloric diets and eating more meals per day, as per nutritional counseling. The waist circumference (WC) decreased significantly, although the body weight decreased non-significantly after adoption of a hypocaloric diet. Conclusion Although there was no significant weight loss, there was a considerable reduction in theWCassociated with hypocaloric diets and with eating a greater number of meals per day.


Resumo Objetivo Avaliar os efeitos do aconselhamento nutricional sobre os hábitos alimentares e os parâmetros antropométricos de adolescentes com sobrepeso e obesidade e com síndrome do ovário policístico (SOP). Métodos Este foi um estudo prospectivo, longitudinal e autocontrolado. Trinta adolescentes com idades entre 13 e 19 anos e diagnosticadas com SOP receberam aconselhamento nutricional. Após 6 meses de acompanhamento, os resultados foram avaliados através do peso corporal, índice demassa corporal (IMC) e a circunferência da cintura (CC). Resultados Sessenta por cento das adolescentes aderiram ao aconselhamento nutricional e, destas, 50% perderam peso. Adolescentes que perderam peso mudaram seus hábitos alimentares adotando dietas hipocalóricas e comendo mais refeições por dia, seguindo orientação nutricional. A circunferência da cintura (CC) diminuiu significativamente, embora o peso corporal tenha diminuído de forma não significativa após a adoção de uma dieta hipocalórica. Conclusão Embora a perda de peso não tenha sido significativa, houve redução considerável da CC associada a dietas hipocalóricas e à ingestão de um maior número de refeições por dia.

ABSTRACT

Abstract Objective This study analyzed the effectiveness of the thyroid-stimulating hormone (TSH) as a predictor of insulin resistance (IR) and its association with the clinical and metabolic parameters of women with polycystic ovary syndrome (PCOS) without overt hypothyroidism. Study Design A cross-sectional study was performed. Women with PCOS and without overt hypothyroidism (n = 168) were included. Methods Receiver operating characteristic (ROC) curve was used to determine the cut-off point for TSH that would maximize sensitivity and specificity for a diagnosis of IR using homeostatic model assessment of insulin resistance (HOMA-IR)≥ 2.71. Clinical and metabolic parameters were compared as a function of the TSH cut-off limit and the presence of IR. Results Thyroid-stimulating hormone ≥ 2.77 mIU/L was associated with a diagnosis of IR, with sensitivity of 47.9% and specificity of 65.3%. There were no differences in clinical, hormonal or metabolic parameters between TSH < 2.77 and TSH of 2.77 - 10 mIU/L. Conclusion In women with PCOS without overt hypothyroidism, TSH ≥2.77 mIU/L is associated with IR; however, with poor sensibility, showing TSH to be a poor predictor of IR in this population. No clinical or metabolic alterations were found that would justify a change in clinical management. Thus, the IR should be investigated in all women with PCOS irrespective of TSH level.


Resumo Objetivo Este estudo analisou a efetividade do hormônio tireoestimulante (TSH) como preditor da resistência insulínica (IR), bem como a associação do TSH com os parâmetros clínicos e metabólicos de mulheres com síndrome do ovário policístico (PCOS) sem hipotireoidismo clínico. Desenho do Estudo Estudo de corte transversal com inclusão de mulheres com PCOS e sem hipotireoidismo clínico (n =168). Métodos Utilizou-se análise através de curva ROC (Receiver operating characteristic) para determinar o valor de corte para o nível sérico de TSH que poderia maximizar a sensibilidade e especificidade para o diagnóstico de IR considerada com avaliação da homeostase de resistência insulínica (HOMA-IR) ≥ 2.71. Parâmetros clínicos e metabólicos foram comparados de acordo com o ponto de corte de TSH determinado e com a presença de IR. Resultados Níveis séricos de TSH ≥2.77 mIU/L estiveram associados com o diagnóstico de IR, com sensibilidade de 47.9% e especificidade de 65.3%. Não foram evidenciadas diferenças nos parâmetros clínicos, hormonais e metabólicos quando TSH < 2.77 ou TSH de 2.77 - 10 mIU/L. Conclusão Em mulheres com PCOS sem hipotireoidismo, TSH ≥2.77 mIU/L está associado a IR, porém com baixa sensibilidade, mostrando que a dosagem de TSH não é um bom preditor de IR nesta população. Também não se evidenciou alteração clínica ou metabólica que justificasse alteração na investigação desta população. Assim, a resistência insulínica deve ser investigada em todas as mulheres com PCOS, independente dos níveis séricos de TSH.

ABSTRACT

ABSTRACT Purpose: Polycystic ovary syndrome (PCOS) is an endocrine disease characterized by chronic anovulation and hyperandrogenism. Hormonal changes can affect tear function. This study evaluates tear function and impact of hyperandrogenism on it in PCOS patients. Methods: Fifty patients with PCOS and thirty control volunteers were examined for tear break-up time, Schirmer-I and tear osmolarity. Also, serum levels of total testosterone, FSH, LH and AMH were determined in venous blood samples in the early follicular phase. PCOS patients were divided into two groups by plasma total testosterone level: Group A with normal (≤0.513 ng/ml;n=27), Group B with higher hormone level (>0.513 ng/ml;n=23). Healthy control group indicated as Group C (n=30). Results: LH, total testosterone levels were higher in the PCOS group than in the control group (p=0.012; p=0.025). Mean values of tear break-up time and Schirmer-I were different between groups and especially Group A and C were near to each other differing from B (p>0.05). Tear osmolarity results were higher in Group B, compared to A and C (p=0.049; p=0.033). No significant difference detected in tear osmolarity value means of Group A and C (p=0.107). AMH levels were higher in Group B, compared to A and C (p=0.002; p=0.001). AMH levels in Group A were higher than that of C (p=0.002). Positive correlation between levels of total testosterone and AMH was detected in all PCOS patients (n=50;Pearson's r=0.579; p<0.001). Conclusion: Tear function can be affected in PCOS patients with hyperandrogenism. Tear osmolarity is the most sensitive and objective assessment method for ocular surface changes in PCOS.


RESUMO Objetivo: A síndrome do ovário policístico (SOP) é uma doença endócrina caracterizada por anovulação crônica e hiperandrogenismo. As alterações hormonais podem afetar a função cardíaca. Este estudo avalia a função lacrimal e o impacto do hiperandrogenismo sobre ela em pacientes com SOP. Métodos: Cinquenta pacientes com SOP e trinta voluntárias de controle foram examinadas para tempo de ruptura lacrimal, Schirmer-I e osmolaridade lacrimal. Além disso, os níveis séricos de testosterona total, FSH, LH e HAM foram determinados em amostras de sangue venoso na fase folicular precoce.As pacientes com SOP foram divididas em dois grupos por nível de testosterona plasmática total: Grupo A com nível normal (≤0.513 ng/ml; n = 27), Grupo B com nível superior de hormônio (> 0,513 ng/ml; n = 23). Grupo de controle saudável indicado como Grupo C (n = 30). Resultados: Os níveis de LH e testosterona total foram maiores no grupo com SOP do que no grupo controle (p = 0,012; p = 0,025). Os valores médios de tempo de ruptura lacrimal e Schirmer-I foram diferentes entre os grupos, e especialmente os Grupos A e C estavam próximos um do outro, diferente do B (p > 0,05). Os resultados de osmolaridade lacrimal foram maiores no Grupo B, em comparação com A e C (p = 0,049; p = 0,033). Não houve diferença significativa detectada em valor médio de osmolaridade lacrimal nos Grupos A e C (p = 0,107). Os níveis de HAM foram maiores no Grupo B, em comparação com A e C (p = 0,002; p = 0,001). Os níveis de AMH no Grupo A foram superiores aos de C (p = 0,002). Uma correlação positiva entre os níveis de testosterona total e AMH foi detectada em todas as pacientes com SOP (n = 50; Pearson's r = 0,579; p < 0,001). Conclusão: a função lacrimal pode ser afetada em pacientes com SOP com hiperandrogenismo. A osmolaridade lacrimal é o método de avaliação mais sensível e objetivo para alterações da superfície ocular em SOP.

ABSTRACT

ABSTRACT Objective The aim of the present study was to determine the prevalence of metabolic syndrome (MS) in infertile Iranian women with polycystic ovary syndrome (PCOS) using the ATPIII criteria. Subjects and methods In this cross-sectional study, 624 women with PCOS were enrolled at a tertiary referral center in Tehran, Iran, between April, 2012 and March, 2013. Diagnosis of MS was according to ATPIII criteria. Also, we divided PCOS patients into following two main groups: (i) with MS (n = 123) and (ii) without MS (n = 501), and then compared variables between two groups. Results The mean age, body mass index (BMI) and waist circumference were 28.6 ± 4.3 years, 26.7 ± 3.7 kg/m2 and 85.2 ± 8.7 cm, respectively. The prevalence of MS was 19.7%. Our findings showed that age, BMI, waist circumference and all metabolic parameters were higher in PCOS women with MS than related values in those without MS. The most and least prevalent forms of MS were low level of high density lipoprotein-cholesterol (HDL-C) and hypertension, respectively. Conclusion It seems the prevalence of metabolic syndrome in our country isn’t as high as western countries. The prevalence rate of MS increased with age and BMI. One of the major cardiovascular risk factors, low level of HDL-C, is the most prevalent metabolic abnormality in our participants.
