RESUMO
PURPOSE: To summarize the effects of metformin treatment on markers of hyperandrogenism in patients diagnosed with polycystic ovary syndrome (PCOS). METHODS: A systematic review, with meta-analysis, of randomized placebo-controlled clinical trials that evaluated the effects of metformin treatment in adult patients with PCOS on the levels of hyperandrogenism markers was conducted. The literature search, data extraction, risk of bias, and the assessment of certainty of evidence were performed independently by two reviewers using a structured form. The results were combined by applying the random effect, and the effect measure presented as a standardized mean difference (SMD). Significant values were considered as p < 0.05 with 95% CI. Furthermore, sensitivity analyses were performed in order to explore possible heterogeneity between studies. RESULTS: Were included 18 studies in the quantitative evaluation and 17 studies (23 reports) in the quantitative evaluation. A significant reduction in total testosterone levels was seen in the metformin-treated group when compared to the control group after combining the results by the sensitivity analysis [SMD: - 0.46 (95% CI: - 0.89 to - 0.02)]. Therefore, FAI values were also regulated by metformin treatment. CONCLUSION: We showed that metformin proved to be effective in reducing total testosterone levels, and the same was observed for free androgen index (FAI) values-a measure influenced by testosterone levels. The protocol of this study was registered at Prospero (CRD42021235761).

Polycystic ovary syndrome (PCOS) is the most common endocrine and metabolic disorder that affects women in reproductive age. This study aimed to evaluate Gal-3 levels and its role on metabolic parameters in women with PCOS. Gal-3 was measured in 44 PCOS and 25 women recruited as control group for the case-control study. Gal-3 levels were similar between PCOS and control groups (p > 0.05), but showed a positive correlation with glucose levels in the oral glucose tolerance test (OGTT) (r = 0.403, p = 0.037), body mass index (BMI) (r = 0.469, p = 0.027), insulin levels (r = 0.453, p = 0.030) and HOMA-IR (r = 0.738, p = 0.037) in PCOS group. The data suggest that Gal-3 plays a role in the pathophysiology of the insulin resistance and obesity in PCOS group.

This study aimed to investigate the association between vitamin D (VitD) levels, polymorphisms in VDR gene (ApaI, BsmI, FokI, and TaqI) and the polycystic ovary syndrome (PCOS) in a group of Brazilian women. A total of 100 patients with PCOS and 100 control women were included. The quantification of 25-hydroxyvitamin D (25(OH)D) was performed in high-performance liquid chromatography (HPLC). Polymorphisms on VDR gene were performed by PCR-RFLP. The BsmI AG genotype was more frequent in PCOS group, while the GG genotype was more frequent in the control group (p = .007). The frequency of the Taql CC genotype was higher in PCOS group, while the CT genotype was the most frequent in the control group (p = .021). Mean serum VitD levels were similar between the groups. However, there was a negative correlation between VitD levels and Ferriman-Gallwey score (p = .031, r = -.260) in the PCOS group. The TaqI and BsmI polymorphisms were associated with PCOS. Moreover, VitD levels are associated with the clinical hyperandrogenism. The data suggest the role of VitD in PCOS development and its complications.

Polycystic Ovary Syndrome (PCOS) is characterized by hyperandrogenism, amenorrhea, and polycystic ovaries. This endocrinopathy is associated with many metabolic disorders such as dyslipidemia and insulin resistance, with increased risk of type 2 diabetes mellitus, metabolic syndrome, and cardiovascular complications. Inflammation is likely to play an important role in the promoting these metabolic imbalances, while prothrombotic and pro-oxidative mechanisms further contribute to the cardiovascular risk of these patients. The etiology of PCOS is still not fully understood, but there is evidence of genetic and environmental components. This review aims to discuss some molecular pathways associated with PCOS that could contribute to the better understanding about this syndrome. Recent evidence suggests that intrauterine exposure of female mice to an excess of anti-Müllerian hormone may induce PCOS features in their post-natal life. High cytokine levels and cytokine gene polymorphisms also appear to be associated with the pathophysiology of PCOS. Furthermore, high levels of microparticles may contribute to the altered hemostasis and enhanced inflammation in PCOS. All these mechanisms may be relevant to clarify some aspects of PCOS pathogenesis and inspire new strategies to prevent the syndrome as well as treat its symptoms and mitigate the risk of long-term complications.

PURPOSE: Proteomic studies suggest an association between haptoglobin (Hp) and polycystic ovary syndrome (PCOS). Hp is a classic inflammatory marker and binds to the intravascular hemoglobin, avoiding the oxidative damages that can be caused by free hemoglobin. Inflammation and oxidative stress are important in the pathogenesis of the PCOS, one of the most frequent metabolic diseases in women. METHODS: To validate these proteomic studies, we developed a controlled cross-sectional study that aimed to evaluate the Hp levels and allelic and genotypic frequencies of Hp1-Hp2 polymorphism in Brazilian women with PCOS. We also investigated the correlation between Hp levels and several important parameters in PCOS as follows: body mass index (BMI), waist circumference (WC), fasting glucose, post-prandial glucose, homeostatic model assessment (HOMA), lipid accumulation product (LAP), C-reactive protein (CRP), and metabolization test of tetrazolium salts (MTTs-serum antioxidant capacity). RESULTS: Plasma Hp levels were higher in the PCOS group than in controls [8.20 (4.04) g/L; 7.98 (3.31) g/L; p = 0.018]. No significant difference was observed in the frequency of Hp1-Hp2 genotypes under additive, recessive, or dominant model of inheritance between the PCOS and the control groups. Plasma Hp levels did not differ according to the genotype. However, plasma Hp showed a negative correlation with MTT (r = - 0.383; p = 0.028), as well as a positive correlation with CRP (r = 0.361; p = 0.014) in the PCOS group. CONCLUSION: Hp1-Hp2 polymorphism is not associated with PCOS but plasma Hp could be a potential biomarker for PCOS and its complications.

The gold standard for diagnosing hirsutism is based on the modified Ferriman-Gallway (mFG) score, requiring trained and in-person evaluation. Our study aimed to evaluate whether using mobile phone images of the nine mFG areas could offer an alternative way to support the diagnostic of hirsutism. All patients from an endocrine outpatient clinic underwent an initial mFG evaluation by two blinded, trained examiners. Then, images of the nine mFG areas were acquired using a mobile device (48 MP) under standard conditions and artificial illumination. A cutoff mFG score of ≥ 4 (suggested by European Society of Human Reproduction and Embryology) or ≥ 6 (proposed by The Endocrine Society) has been established as the criteria for diagnosing hirsutism. After storage, the individual patients' images were submitted for mFG analysis by three independent, blinded examiners. Overall, 70 females were evaluated; 27.5% of the patients had an mFG score ≥ 4. The mean age ± SEM was 33.2 + 1.13 years. The first consideration was the evaluation of the examiners who analyzed the images. In this group, the inter-rater reliability based on the Fleiss' Kappa identified an agreement of 81.4%, with a Kappa index of 0.75 considered strong for clinical evaluations. For mFG score ≥ 6, the agreement was 77%, and the performance of Kappa Index was 0.62 (moderate). Independently of the cutoffs, the Bland-Altman analysis established a concordance of 0.89 (95% CI [0.83, 0.92]) between the in-person and image-based methods to score mFG. The lower limit of agreement of the estimated mFG scores was - 2.08 (95% CI [- 2.73, - 1.43]), and the upper limit of agreement was 4.14 (95% CI [3.491, 4.79]). We observed acceptable concordance between the image-based and in-person evaluation of mFG scores. Our results support the use of image acquisition of mFG areas as a valid approach for diagnosing hirsutism.

INTRODUCTION: Women with Polycystic Ovary Syndrome (PCOS) have a higher prevalence of Nonalcoholic Fatty Liver Disease (NAFLD) than the general population. PCOS and NAFLD have common metabolic risk factors, however, the role of diet in NAFLD development is still uncertain in PCOS women. OBJECTIVE: To evaluate and compare the dietary patterns and nutritional intake in patients with PCOS with and without NAFLD. METHOD: Cross-sectional study that included patients with PCOS diagnosed according to Rotterdam criteria. All participants were submitted to abdominal ultrasound to investigate liver steatosis. Dietary profile was assessed by 24-hour food recall (24hR), and Food Frequency Questionnaire (FFQ). Diet quality was assessed by the Healthy Eating Index (HEI) adapted for the Brazilian population. Physical activity practice was also assessed. RESULTS: 87 participants were included (average age 35.2 ± 5.7 years), among whom, 67 (77%) had NAFLD. The group with PCOS and NAFLD presented higher body mass index (BMI) (34.9 ± 4.5 vs. 30.4 ± 4.9 kg/m2; p = 0.001), Waist Circumference (WC) (103 [97â113] vs. 95 [87.5â100] cm; p < 0.001) and were considered physically active less frequently than those without NAFLD (34.3% vs. 60%; p = 0.04). Food intake and dietary patterns assessed by 24hR, FFQ and HEI presented no difference between the groups. CONCLUSIONS: PCOS women with coexistent NAFLD had higher BMI, WC and were less physically active than those without NAFLD. Dietary evaluation showed that PCOS women with NAFLD had no significant difference in macro and micronutrients or food group intake and diet quality in comparison to those without NAFLD.

Irisin is a recently discovered adipomyokine involved in the regulation of glucose and lipid, which also exhibits anti-inflammatory and neuroprotective properties. Here we aimed to compare irisin peripheral levels between individuals with behavioral variant frontotemporal dementia (bvFTD) and cognitively healthy matched controls, in addition to investigating whether there is a correlation between irisin and pro-inflammatory cytokines (IL-6 and TNF) concentrations. Twenty-nine individuals participated in this study, being 18 patients with probable bvFTD and 11 controls. Irisin, IL-6 and TNF levels were measured in EDTA plasma through ELISA. There was no difference of the levels of irisin between the groups (p = 0.964). However, in the bvFTD, but not in control group, the levels of irisin were positively correlated with the concentration of IL-6 (r = 0.637, p = 0.006) and TNF (r = 0.517, p = 0.034). The results suggest that the production of irisin in bvFTD could be related to chronic inflammatory and neurodegenerative states in these patients.

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 Objective The aim of this study was to evaluate the efficacy of a self-assessment questionnaire for hirsutism using the latest cutoff values recommended by the Endocrine Society (ES) for Latin-American women and by the European Society for Human Reproduction and Embryology (ESHRE). Subject and methods Female premenopausal outpatients (n = 188) completed a self-assessment questionnaire, scoring hair presence across the nine areas evaluated by the modified Ferriman-Gallwey (mFG) scale. The results were compared with clinician-assessed scores rated independently by two trained physicians. Scores in the Hirsuta questionnaire, derived from self-assessment of five areas of the mFG scale, were also evaluated. Results The ethnic composition of the sample was as follows: 23.1% white, 25.8% black, 48.9% mixed, and 2.1% other backgrounds (Indigenous, Asian). The participants had age and BMI of (mean ± standard deviation) 33.7 ± 9.9 years and 29.8 ± 7.21 kg/m2, respectively. The most common areas of excessive hair growth were the chin, upper and lower abdomen, and thighs. Relative to clinician-assessed mFG scores, self-assessed mFG scores had an accuracy of 80% using ES criteria for hirsutism diagnosis, with a sensitivity of 95.45%, specificity of 56.25%, positive predictive value of 30.10%, and negative predictive value of 98.40%. Self-assessed mFG had lower accuracy (71%) for diagnosing hirsutism when the ESHRE criteria were applied. Conclusions Self-assessed mFG had low specificity, limiting its application. The results of this study do not support the use of the self-assessed mFG or Hirsuta scores for diagnosing hirsutism in a clinical setting, although both scoring systems may be useful for screening hirsutism in epidemiological studies.
RESUMO
INTRODUCTION: Brazil is a large country, with a population of mixed ethnic background and broad variation in dietary and physical activity traits across its five main regions. Because data on Brazilian women with polycystic ovary syndrome (PCOS) are still scarce, a nation-wide collaborative study was designed to determine the prevalence of metabolic and reproductive abnormalities and the presence of anxiety and depression in Brazilian women with PCOS. In addition, the study aims at describing how these characteristics are distributed across PCOS phenotypes and at detecting associations with regional demographic and lifestyle aspects, genetic variants, and epigenetic markers. METHODS AND ANALYSIS: The Brazilian PCOS study is being conducted in the outpatient clinics of eight university hospitals within the public healthcare network (Unified Health System) across the country. Additional centres will be included following completion of the research ethics approval process. The sample includes women with PCOS according to Rotterdam criteria at inclusion in the study and a control group of healthy women matched by age, socioeconomic status and geographical region. Data will be collected in each centre and incorporated into a unified cloud database. Clinical, demographic, socioeconomic, psychological, metabolic, epigenetic and genotypic variables will be evaluated. The data resulting from this study will be useful to guide specific public strategies for primary and secondary prevention of metabolic and reproductive comorbidities in the PCOS population of Brazil. ETHICS AND DISSEMINATION: The study protocol was approved by each local Research Ethics Committee. Written informed consent will be obtained from each participant. During data collection, analysis and publication, care will be taken to ensure confidentiality of participant information. Study results will be published in peer-reviewed journals and disseminated at international conferences. This research protocol was registered with the Research Ethics Committee of HCPA, through Plataforma Brasil. TRIAL REGISTRATION NUMBER: CAAE 18082413.9.1001.5327.

RESUMO
OBJECTIVE: Polycystic ovary syndrome (PCOS) is the most common endocrine metabolic disorder in women between menarche and menopause. Clinical hyperandrogenism is the most important diagnostic criterion of the syndrome, which manifests as hirsutism in 70% of cases. Hirsute carriers of PCOS have high cardiovascular risk. Lipid accumulation product (LAP) is an index for the evaluation of lipid accumulation in adults and the prediction of cardiovascular risk. The aim of this study was to evaluate the association between LAP and hirsutism in women with PCOS. METHODS: This was a cross-sectional observational study of a secondary database, which included 263 patients who had visited the Hyperandrogenism Outpatient Clinic from November 2009 to July 2014. The exclusion criteria were patients without Ferriman-Gallwey index (FGI) and/or LAP data. We used the Rotterdam criteria for the diagnosis of PCOS. All patients underwent medical assessment followed by measurement and recording of anthropometric data and the laboratory tests for measurement of the following: thyroid-stimulating hormone, follicle-stimulating hormone, prolactin, total testosterone, sex hormone binding globulin, 17-α-hydroxyprogesterone (follicular phase), glycohemoglobin A1c, and basal insulin. In addition, the subjects underwent lipid profiling and oral glucose tolerance tests. Other laboratory measurements were determined according to clinical criteria. LAP and the homeostatic model assessment index (HOMA-IR) were calculated using the data obtained. We divided patients into two groups: the PCOS group with normal LAP (< 34.5) and the PCOS group with altered LAP (> 34.5) to compare the occurrence of hirsutism. For statistical analysis, we used SPSS Statistics for Windows® and Microsoft Excel programs, with descriptive (frequencies, percentages, means, and standard deviations) and comparative analyses (Student's t-test and Chi-square test). We considered relations significant when the p-value was ≤ 0.05. RESULTS: LAP was high in most patients (n = 177; 67.3%) and the FGI indicated that 58.5% of the patients (n = 154) had hirsutism. The analysis by LAP quartiles showed a positive correlation (p = 0.04) among patients with a high FGI and an upper quartile LAP (> 79.5) when compared with those with LAP < 29.0 (lower quartile). CONCLUSION: This study demonstrated an association between high LAP and hirsutism. The FGI could represent a simple and low-cost tool to infer an increased cardiovascular risk in women with PCOS.

Objetivo A síndrome dos ovários policísticos (SOP) é o distúrbio endócrino mais comumemmulheres entre amenarca e a menopausa. O hiperandrogenismo clínico é o critério diagnóstico mais importante da síndrome, que se manifesta como hirsutismo em70% dos casos. Portadores de SOP hirsutas têmelevado risco cardiovascular. O Lipid accumulation product (LAP) é um índice para a avaliação da acumulação de lípidos nos adultos e é um preditor de risco cardiovascular. O objetivo deste estudo é avaliar a associação entre LAP e hirsutismo em portadoras da SOP. Métodos Estudo observacional transversal de banco de dados secundário, que incluiu 263 pacientes do Ambulatório de Hiperandrogenismo no período de novembro de 2009 a julho de 2014. Foram excluídas pacientes sem o índice de Ferriman-Gallwey e/ ou LAP. Foram utilizados como critérios diagnósticos da SOP os critérios de Rotterdam. Todas as pacientes foram submetidas à avaliação médica seguida da aferição e registro dos dados antropométricos e a realização dos seguintes exames laboratoriais: hormônio estimulante da tireoide (TSH), hormônio folículo estimulante (FSH), prolactina (PRL), Testosterona total, globulina ligadora dos hormônios sexuais (SHBG), 17-α- hidroxiprogesterona, (fase folicular), perfil lipídico, teste oral de tolerância à glicose, glico-hemoglobina a1C, insulina basal. Outras dosagens laboratoriais foram determinadas à critério clínico. O LAP e o HOMA-IR (homeostatic model assessment) foram calculados com os dados obtidos. As pacientes foram divididas em dois grupos: grupo das portadoras de SOP com LAP normal (LAp < 34,5) e grupo das portadoras de SOP com LAP alterado (LAP >34,5) para as comparações do hirsutismo. Para a análise estatística, foram utilizados os programas SPSS Statistics for Windows(r) e Microsoft Excel(r), sendo feitas análises descritivas (frequências, percentuais, médias, desviospadrão) e comparativas (t-Student e qui-quadrado). Foram consideradas relações significativas quando p-valor foi menor ou igual a 0,05. Resultados O LAP foi elevado na maioria das pacientes (n = 177; 67,3%) e o índice de Ferriman-Gallwey (IF) demonstrou que 58,5% das pacientes (n = 154) eram hirsutas. A análise por quartis de LAP, demonstrou correlação positiva (p = 0,04) entre pacientes comIF elevado e LAP no quartil superior (>79,5) quando comparadas àquelas com LAP menor que 29,0 (quartil inferior). Conclusão O estudo demonstrou associação do LAP elevado e hirsutismo. O escore de Ferriman-Gallwey poderia representar uma ferramenta simples e de baixo custo para inferir risco cardiovascular aumentado em portadoras da síndrome.

INTRODUÇÃO: A síndrome dos ovários policísticos (SOP) é uma desordem endócrina comum que afeta 5 a 10% das mulheres em idade reprodutiva. A associação entre síndrome metabólica e alterações relacionadas à glicose e insulina é frequente em pacientes com SOP, eleva o risco cardiovascular dessas pacientes. O LAP é um índice de risco cardiovascular emergente que se baseia na combinação da circunferência abdominal (CA) e triglicérides (TGL) em jejum e reflete de forma simples a acumulação lipídica em adultos. OBJETIVOS: O presente estudo avaliou as possíveis correlações entre síndrome metabólica e o LAP nos parâmetros metabólicos e reprodutivos de pacientes com SOP. MATERIAIS E MÉTODOS: O estudo incluiu 299 pacientes portadoras de SOP, definida pelos critérios de Rotterdam, acompanhadas no Ambulatório de Hiperandrogenismo do Hospital das Clínicas da Universidade Federal de Minas Gerais (HC‐UFMG). Foram avaliados: (1) dosagens séricas de triglicérides, testosterona total, glicemia de jejum e duas horas após sobrecarga de 75 gramas de dextrosol (GPD), TSH; (2) cálculo do LAP; (3) cálculo do índice de Ferriman; (4) avaliação do volume dos ovários; (5) medida da circunferência abdominal e (6) presença ou não de síndrome metabólica. RESULTADOS: A média do LAP foi 60,9 e a mediana 51,3. Pacientes com ou sem síndrome metabólica quando comparadas entre si não apresentaram diferenças quanto a volume ovariano, testosterona total, índice de Ferriman, glicemia de jejum e pós‐dextrosol. As mulheres com síndrome metabólica tiveram valores de TSH mais altos do que as mulheres sem síndrome metabólica. Já as mulheres no quartil superior do LAP tiveram TSH, índice de Ferriman e GPD maiores do que as mulheres nos quartis inferiores de LAP...
INTRODUCTION: Polycystic Ovary Syndrome (SOP) is a common endocrine disorder that affects 5-10% of women of reproductive age. The association between metabolic syndrome and changes related to glucose and insulin is frequent in patients with SOP, increasing the cardiovascular risk of these patients. The LAP is an emerging cardiovascular risk based on the combination of waist circumference (WC) and triglycerides (TGL) and fasting simply reflects the lipid accumulation in adults. OBJECTIVES: This study examined the possible correlation between metabolic syndrome or LAP and reproductive and metabolic parameters in patients with SOP. MATERIALS AND METHODS: The study included two hundred ninety-nine patients with SOP, defined by the Rotterdam criteria followed at HC-UFMG who had assessed their levels of triglycerides, total testosterone, fastingand two hours after 75 grams of overload dextrosol (GPD), TSH, LAP, Ferriman index, ovarian volume and abdominal circumference, and the presence or absence of metabolic syndrome. RESULTS: The mean LAP was 60.9 and the median 51.3. Patients with and without metabolic syndrome when compared to each others howed no differences in ovarian volume, total testosterone, Ferriman, fastingand post-dextrosol. Women with metabolic syndrome had higher TSH levels than women without metabolic syndrome. The women in the top quartile of the LAP had TSH, Ferriman and GPD higher than women in the lower quartiles of LAP...

BACKGROUND: The Polycystic Ovary Syndrome (PCOS) is the most common endocrinopathy and one of the main causes of infertility in women. OBJECTIVES: This study aimed to evaluate the correlation between clinical hyperandrogenism assessed by modified Ferriman-Gallwey (F-G) score and metabolic parameters in Polycystic Ovary Syndrome women. METHODS: This observational study included fifty Polycystic Ovary Syndrome subjects. Detailed information about body mass index (BMI) and abdominal circumference (AC) were obtained from each subject. F-G score was applied to assess hirsutism through visual method. Serum levels of insulin, glucose and testosterone were measured. RESULTS: A positive correlation was observed between F-G score with body mass index, abdominal circumference and insulin. CONCLUSIONS: Obesity, mainly abdominal adipose tissue, and insulin levels correlate with hyperandrogenism in Polycystic Ovary Syndrome women, analyzed by F-G score. F-G score could be a marker to evaluate metabolic disorders in Polycystic Ovary Syndrome women.
JUSTIFICATIVA: A Síndrome dos Ovários Policísticos (SOP) é a endocrinopatia mais comum e uma das principais causas de infertilidade em mulheres. OBJETIVOS: O presente estudo teve como objetivo avaliar a correlação entre hiperandrogenismo clínico, avaliado pela escala de Ferriman-Gallwey (FG) modificada e parâmetros metabólicos em mulheres com a Síndrome dos Ovários Policísticos. MÉTODOS: Este estudo observacional incluiu cinquenta mulheres com Síndrome dos Ovários Policísticos. Informações detalhadas sobre o índice de massa corporal (IMC) e circunferência abdominal (CA) foram obtidas de cada participante. A escala FG foi aplicada para avaliar o hirsutismo através do método visual. Níveis séricos de insulina, glicose e testosterona foram também avaliados. RESULTADOS: Observou-se uma correlação positiva entre a escala FG e o índice de massa corporal, circunferência abdominal e insulina. CONCLUSÕES: A obesidade, principalmente o tecido adiposo abdominal, e os níveis de insulina se correlacionam com hiperandrogenismo em mulheres com Síndrome dos Ovários Policísticos, analisados por meio da escala FG. Desta forma, esta escala poderia ser um marcador para avaliar distúrbios metabólicos em mulheres com Síndrome dos Ovários Policísticos.

O objetivo com esta pesquisa foi caracterizar o estado nutricional e o consumo alimentar de pacientes com síndrome de ovários policísticos (SOPC). Trata-se de estudo transversal realizado com portadoras de SOPC atendidas pela Equipe de Nutrição em serviço de atenção secundária à saúde. Foram obtidas informações sociodemográficas e perfil de saúde, medidas antropométricas, dados bioquímicos e do consumo alimentar. Participaram do estudo 54 mulheres, com média de 31,31± 5,76 anos, sendo 63% classificadas com algum grau de obesidade, 74,1% com risco cardiovascular segundo a razão cintura-quadril e 90,8% com circunferência de cintura aumentada. Houve correlação positiva entre a resistência insulina, mensurada pelo índice HOMA-IR, e índice de massa corporal (r=0,729; p=0,028). Além disso, houve elevada prevalência de consumo insuficiente de calorias (73,6%), carboidratos (54,7%) e micronutrientes (cálcio - 96,2%; ferro - 98,1%), contrastando com 71,7% de ingestão excessiva de lipídeos. Não houve associação entre estado nutricional, parâmetros bioquímicos e consumo alimentar (p>0,05). Concluiu-se que pacientes diagnosticadas com SOPC apresentam alta prevalência de obesidade e inadequações nutricionais, denotando importância de medidas de intervenção nutricional como parte do tratamento não farmacológico.
The present study aims at characterizing the nutritional status and food intake of patients with Polycystic Ovary Syndrome (PCOS). It is a cross-sectional study performed in patients with PCOStreated in secondary health care service by nutrition specialists.socio-demographic information, health profile, anthropometric measurements, biochemical and food intake data were obtained. The study included 54 women with an average age of 31.31 ±5.76 years: 63% were classified as obese at different levels; 74.1% presented cardiovascular risk according to waist-hip ratio, and 90.8% an increased waist circumference. Correlations between insulin resistance, measured by HOMA-IR index, and body mass index (r = 0.729, p = 0.028) were observed. Evaluation of nutritional intake revealed an insufficient amount of calories (73.6%), carbohydrates (54.7%), and micronutrients (calcium, 96.2%; iron, 98.1%). However 71.7% presented an excessive intake of lipids.There was no association between nutritional status, biochemical parameters and food intake (p> 0.05). PCOS patients present a high prevalence of obesity and nutritional inadequacies. Therefore, nutritional intervention strategies constitute important tools as a non-pharmacological treatment.

É apresentada uma revisäo de 26 casos de pseudohermafroditismo masculino, diagnosticados na infância (idades entre 1 dia e 15 anos) e acompanhados no setor de endocrinologia infantil do Hospital das Clínicas, Departamento de Pediatria da Faculdade de Medicina da UFMG, enfatizando-se aspectos das dificuldades diagnosticas, a evoluçäo clínica e a conduta terapêutica. Quatorze crianças apresentavam uma das formas de resistência periférica aos androgênios, oito apresentavam disgenesia gonadal e 4 genitálía ambígua como parte de uma síndrome malformativa. Cerca de 50 por cento teve o reconhecimento da genitália ambígua ao nascer, mas apenas 15 por cento teve seu diagnóstico correto no primeiro mês de vida. Em três casos optou-se pela mudança do sexo social estabelecido. Embora ocorra raramente, chamamos a atençäo para a necessidade de diagnóstico precoce e correto dos distúrbios de diferenciaçäo sexual possibilitando assim a prevençäo de futuras complicaçöes para a criança e sua família.
