ABSTRACT

Muitas vezes, torna-se um grande desafio para o ginecologista a identificação daquelas com maior ou menor chance de concepção. Vários marcadores laboratoriais e ultrassonográficos, conhecidos conjuntamente como testes de avaliação da reserva ovariana, são estudados há décadas com a intenção de se buscar uma ferramenta para a predição do potencial reprodutivo. E, embora ainda se busquem os marcadores ideais para aplicação clínica, mais difícil do que os definir é definir quando eles estão indicados. Este artigo de atualização, assinado pela Comissão Nacional Especializada em Ginecologia Endócrina da Febrasgo, pretende oferecer ao leitor as ferramentas necessárias para o uso racional dos testes de avaliação da reserva ovariana no cotidiano.(AU)


Often, it becomes a great challenge for the gynecologist to identify women with a greater or lesser chance of conception. Several laboratory and ultrasound markers, known jointly as ovarian reserve evaluation tests, have been studied for decades with the intention of seeking a tool for the prediction of reproductive potential. And, while the ideal markers for clinical application are still sought, defining them is as harder as defining when they are indicated. This update article, signed by the National Specialized Committee on Gynecologic Endocrinology, Febrasgo, intends to offer the reader the necessary tools for the rational use of ovarian reserve evaluation tests in daily practice.(AU)

ABSTRACT

Objective. To compare macular thickness (MT) and retinal nerve fiber layers (RNFL) between women with polycystic ovary syndrome (PCOS) and healthy women. Materials and Methods. The study included 45 women with PCOS and 47 ovulatory women undergoing clinical-gynecological and ophthalmic evaluations, including measurement of MT, RNFL, and optic disc parameters using optical coherence tomography. Results. The superior RNFL around the optic nerve was significantly thicker in PCOS than in healthy volunteers (P = 0.036). After stratification according to insulin resistance, the temporal inner macula (TIM), the inferior inner macula (IIM), the nasal inner macula (NIM), and the nasal outer macula (NOM) were significantly thicker in PCOS group than in control group (P < 0.05). Both the presence of obesity associated with insulin resistance (P = 0.037) and glucose intolerance (P = 0.001) were associated with significant increase in the PC1 mean score, relative to MT. A significant increase in the PC2 mean score occurred when considering the presence of metabolic syndrome (P < 0.0001). There was a significant interaction between obesity and inflammation in a decreasing mean PC2 score relative to macular RNFL thickness (P = 0.034). Conclusion. Decreased macular RNFL thickness and increased total MT are associated with metabolic abnormalities, while increased RNFL thickness around the optic nerve is associated with hormonal changes inherent in PCOS.

ABSTRACT

A síndrome do ovário policístico é a endocrinopatia ginecológica mais frequente das mulheres em idade reprodutiva, clinicamente caracterizada pela presença de anovulação crônica hiperandrogênica, hirsutismo e infertilidade. Além das alterações reprodutivas, uma proporção considerável das portadoras da síndrome apresenta anormalidades metabólicas como: resistência à insulina e obesidade, com aumento significativo do risco para o desenvolvimento de intolerância à glicose; diabetes mellitus e doença cardiovascular. No entanto, os mecanismos fisiopatológicos que vinculam a obesidade, a resistência à insulina e os demais distúrbios metabólicos presentes na síndrome do ovário policístico ainda não estão completamente esclarecidos. Estudos recentes sugerem que a adiponectina, uma proteína secretada especificamente pelo tecido adiposo, que apresenta propriedades antiaterogênicas, anti-inflamatórias e sensibilizadora à ação da insulina, poderia apresentar um importante papel integrador na patogênese desses distúrbios metabólicos.


Polycystic ovary syndrome is the most common gynecologic endocrinopathy of reproductive age women. It is clinically characterized by hyperandrogenic chronic anovulation, hisrutism and infertility. In addition to reproductive alterations, a significant proportion of polycystic ovary syndrome women display metabolic abnormalities such as insulin resistance and adiposity, predisposing to greater risk of developing glucose intolerance; diabetes mellitus and cardiovascular disease. However, the physiopathologic mechanisms linking obesity, insulin resistance and the other polycystic ovary syndrome metabolic disturbances are not completely understood. Recent studies suggest that adiponectin, a protein specifically secreted by adipose tissue and which has antiatherogenic, anti-inflammatory and insulin-sensitizing properties, could play an important and integrative role in the pathogenesis of these metabolic disturbances.

ABSTRACT

OBJECTIVE: To determine the prevalence of the metabolic syndrome (MetS) and its components in Brazilian women with polycystic ovary syndrome (PCOS). DESIGN: Cross-sectional study. SETTING: University Hospital, Federal University of Rio Grande do Norte, Natal-RN, Brazil. PATIENT(S): 102 women with PCOS by the Rotterdam consensus criteria. INTERVENTION(S): None. MAIN OUTCOME MEASURE(S): Clinical and biochemical parameters for MetS as defined by the National Cholesterol Education Program Adult Treatment Panel (NCEP ATP III). RESULT(S): The prevalence for individual components of MetS were high-density lipoprotein cholesterol level <50 mg/dL in 69.6%, waist circumference >or=88 cm in 57.9%, triglyceride level >or=150 mg/dL in 31.7%, blood pressure >or=130/85 mm Hg in 18.6%, and fasting glucose concentrations >or=110 mg/dL in 2.9%. Three or more of these individual criteria were present in 29 (28.4%) of the patients. The prevalence of MetS increased with body mass index: 3.2%, 19.2% and 52.3% for normal, overweight, and obese women, respectively. CONCLUSION(S): These findings indicate that Brazilian women with PCOS have a high prevalence of MetS and its individual components, particularly a decreased high-density lipoprotein cholesterol level. Thus, these women are at increased risk of diabetes mellitus and cardiovascular disease.

ABSTRACT

A síndrome HELLP é uma grave complicação da pré-eclampsia, cursando com elevada morbimortalidade materna e perinatal. Controvérsias ocorrem com relação à incidência, critérios de diagnóstico e conduta nesta síndrome. As mortes perinatais estão relacionadas com o descolamento prematuro da placenta, asfixia intra-útero e prematuridade. A utilização de altas doses de corticóide no tratamento parece proporcionar melhores resultados maternos e perinatais, no entanto, são necessários estudos randomizados para sua completa e segura utilização na síndrome HELLP. O maior desafio diante desta síndrome é o diagnóstico precoce, intervenção oportuna e a prevenção das complicações. Sendo assim, as pacientes com suspeita de síndrome HELLP deverão ser encaminhadas para um serviço de assistência terciária para que sejam assistidas por uma equipe especializada, e tão logo possível, promova-se a interrupção da gestação.

ABSTRACT

No presente trabalho foram determinados os níveis de T4, T3, captaçäo de T3 por resina (RT3) e T3 reverso (rT3) em amostras de sangue colhidas de 21 parturientes clinicamente normais, com índice de tiroxina livre (ITL) normal, de seus conceptos e de oito parturientes clinicamente normais, mas com ITL abaixo da normalidade, e seus conceptos. As amostras de sangue foram colhidas por punçäo venosa do antebraço (sangue periférico materno - PM) durante a gase expulsiva do trabalho de parto; do espaço interviloso da placenta (EIV) imediatamente após a expulsäo placentária, e dos vasos - artéria (A) e veia (V) - umbilicais, imediatamente após ligadura do cordäo. Quando os resultados dos compartimentos fetais (A e V) foram comparados näo houve diferenças entre os grupos I e II para todos os hormônios. Entretanto, para os compartimentos maternos, os valores de T4, T3, ITL e T3 foram maiores no grupo I. Para o RT3 näo houve diferenças. Apesar da variaçäo materna entre os dois grupos, näo foram observadas diferenças entre os grupos I e II, nos compartimentos fetais. Estes dados sugerem que há uma relativa independência fetal em relaçäo ao organismo materno, no que diz respeito ao metabolismo dos hormônios tireoideanos
