RESUMO

Contexto: Luteoma é neoplasia rara e benigna do ovário, específica da gravidez. Considera-se que seja causada por efeitos hormonais, principalmente da gonadotrofina coriônica. Objetivo: Analisar artigos selecionados sobre luteoma da gravidez e realizar revisão bibliográfica a partir dessas publicações. Desenho: A busca dos artigos foi realizada por meio da plataforma PubMed. Procedeu-se uma busca aos descritores da doença e seu correspondente em inglês (luteoma) no portal da BVSalud. Métodos: Consistiu em revisão bibliográfica, onde foram utilizados artigos publicados de 1972 até 2022. Resultados: A origem celular dos luteomas ainda é desconhecida, mas considera-se que tal processo ocorra devido a uma reação hiperplásica à gravidez, visto que o efeito de virilização regride após o parto. Discussão: Sendo pouco diagnosticado, tendo menos de 200 casos reportados, são geralmente achados durante parto cesáreo ou durante ligadura tubária no pós-parto. Seu aparecimento está relacionado a fatores hormonais da gravidez e hiperplasia ocasionada pela luteinização das células estromais. Os efeitos do luteoma gravídico no organismo estão relacionados, além da virilização da paciente e do feto, com o surgimento da síndrome do ovário policístico e diabetes. Conclusões: Tendo baixa incidência, o luteoma gravídico pode se apresentar como desafio para seu diagnóstico adequado. O diagnóstico precoce permitirá o tratamento adequado, evitando-se efeitos indesejáveis, virilizantes, para a gestante e para o nascituro. É fundamental o preparo dos profissionais de saúde para o diagnóstico e tratamento do luteoma gravídico.

RESUMO

Introducción y objetivos: Determinar los hallazgos clínicos y ecográficos en pacientes que presentan menos de 12 folículos ováricos. Método: Estudio observacional (cohorte histórica) con 505 pacientes seleccionadas mediante muestreo consecutivo, entre el 14 de enero del 2019 y el 15 de marzo del 2021, que consultan por diversas alteraciones ginecológicas. Se generan dos grupos de pacientes, las que presentaron uno a tres folículos en uno de los ovarios (n = 377) y las que presentaban 4 a 11 folículos (n = 128). Se midió como resultado primario la presencia de al menos un signo clínico de hiperandrogenismo. Resultados: De 505 pacientes analizadas, al comparar las que presentaron 4 a 11 folículos en uno de los ovarios (n = 377) con las que presentaban 1 a 3 folículos (n = 128), las primeras mostraron mayor presencia de signos de hiperandrogenismo, endometrio en fase lútea de mayor espesor y un patrón menstrual con uno a cuatro días de sangrado menstrual abundante, diferencias todas estadísticamente significativas (p < 0,05). Conclusión: En pacientes con 4 a 11 folículos en uno de sus ovarios, se observaron signos de hiperandrogenismo, similares al síndrome de ovario poliquístico.


Introduction and objectives: Determine the clinical and ultrasound findings in patients who present less than 12 ovarian follicles in the ultrasound count. Method: Observational study (historical cohort) with 505 patients selected by consecutive sampling, between January 14, 2019 and March 15, 2021, who consulted for different gynecological disorders. Two groups of patients were generated: those with 1 to 3 follicles in one of the ovaries (n = 377) and those with 4 to 11 follicles (n = 128). The primary outcome was the presence of at least one clinical sign of hyperandrogenism. Results: Of 505 patients analyzed, when comparing those who presented 4 to 11 follicles in one of the ovaries (n = 377) with those who presented 1 to 3 follicles (n = 128), the first group showed a greater presence of signs of hyperandrogenism, thicker endometrium in luteal phase and a menstrual pattern with one to four days of heavy menstrual bleeding, all differences were statistically significant (p < 0.05). Conclusion: In patients with 4 to 11 follicles in one of their ovaries, signs of hyperandrogenism, similar to polycystic ovary syndrome, were observed.

RESUMO

INTRODUCTION: The prevalence of polycystic ovarian syndrome (PCOS) in adolescent girls is between 1 and 4.3%. It remains controversial whether women with a history of idiopathic central precocious puberty (ICPP) are at increased risk for PCOS. Our objective was to assess the prevalence of PCOS in adolescents with a history of ICPP compared with healthy adolescents and the prevalence of PCOS among ICPP girls who have received or not gonadotropin-releasing hormone analogue (GnRHa) treatment. METHODS: We assessed post-menarcheal girls with a history of ICPP. Girls were evaluated at gynecological age ≥2.5 years. Data collected were age at menarche, menstrual cycle characteristics, BMI, clinical hyperandrogenism (HA), total and free testosterone levels. PCOS diagnosis was defined by criteria for adolescents. Subjects were also analyzed regarding whether or not they had received GnRHa treatment. RESULTS: Ninety-four subjects were assessed, and 63 had been treated with GnRHa. Menstrual disorders were found in 29%, clinical HA in 36%, and biochemical HA in 23%. Twelve percent met the diagnostic criteria for PCOS. There was no difference in BMI or in the incidence of menstrual dysfunction or hyperandrogenemia between treated and untreated patients. A higher proportion of clinical HA was found in untreated patients when compared to treated girls. The relative risk (RR) of developing PCOS in ICPP girls was 2.5 compared to a population of healthy adolescents. This RR was not higher in patients who received treatment with GnRHa than in those who did not. CONCLUSION: Adolescent girls with a history of ICPP have an increased risk of PCOS. This risk seems not to be related to GnRHa treatment.

RESUMO

Abstract Objective To identify the impact of redox imbalance on the clinical evolution of patients with polycystic ovary syndrome and carry out a qualitative and quantitative projection of the benefits of vitamin D supplementation. Data sources Combinations of the keywords polycystic ovary syndrome, vitamin D, oxidative stress, reactive oxygen species, antioxidant, and free radicals were used in PubMed, Cochrane Library, LILACS, EMBASE, and Web of Science databases. The last search was conducted on August 22, 2023.Selection of studies: Based on the inclusion and exclusion criteria, studies were selected considering a low risk of bias, published in the last 5 years in English, which investigated the effects of vitamin D supplementation in women with PCOS, focusing on oxidative stress markers. Of the 136 articles retrieved, 6 intervention studies (445 women) were included. Data collection The risk of bias in included studies was assessed using the Jadad scale, and analysis and visualization of continuous data were performed using Review Manager 5.4.1, summarized as standardized mean differences (SMD) with confidence intervals (CI) of 95%. Data synthesis Vitamin D effectively reduced malondialdehyde (P=0.002) and total testosterone (P=0.0004) levels and increased total antioxidant capacity levels (P=0.01). Although possible improvements in the modified Ferriman-Gallwey hirsutism score, levels of sex hormone-binding globulin, and free androgen index were identified and the results were not statistically significant. Conclusion Vitamin D is a promising alternative for the treatment of PCOS with a positive influence on the oxidative, metabolic, and endocrine disorders of this syndrome.

RESUMO

A hiperplasia adrenal congênita (HAC) pode cursar com redução da fertilidade na mulher. Entretanto, nos casos em que ocorre gestação, os recém-nascidos das por- tadoras de hiperplasia adrenal congênita exibem risco de hiperandrogenismo, com todas as suas consequências. A presente revisão atualiza o tema, considerando também as necessidades da assistência a essas pacientes. A busca identificou 294 artigos na base de dados MEDLINE/PubMed de 1961 a março/2023, e os resultados mostraram que as portadoras de hiperplasia adrenal congênita exibem significativa redução da fertilidade. Nos casos de interesse de gestação, as portadoras de hiper- plasia adrenal congênita devem fazer um planejamento reprodutivo, envolvendo a fase antenatal, o acompanhamento pré-natal especializado, o parto e o aleitamento.


Congenital adrenal hyperplasia may lead to reduced male and female fertility. Mo- reover, when the pregnancy occurs, the newborns of patients with congenital adrenal hyperplasia are at risk of hyperandrogenism with all its consequences. This review updates the theme and emphasizes assistance needs. The search identified 294 ar- ticles in the MEDLINE/PubMed database from 1961 to March/2023, and the results showed that patients with congenital adrenal hyperplasia truly exhibit a significant reduction in fertility. In cases of interest in pregnancy, patients with congenital adre- nal hyperplasia should carry out reproductive planning, involving the antenatal pha- se, specialized prenatal care, till delivery and breastfeeding.

RESUMO

PCOS is an endocrine disorder characterized by chronic anovulation, hyperandrogenism, and polycystic ovaries. Its etiology is uncertain. It is debated whether BPA would be a component of the environmental factor in the etiology of PCOS. Contamination by BPA can occur from food packaging (exposure during the diet) and through skin absorption and/or inhalation. It can be transferred to the fetus via the placenta or to the infant via breast milk, and it can be found in follicular fluid, fetal serum, and amniotic fluid. The phenolic structure of BPA allows it to interact with Estrogen Receptors (ERs) through genomic signaling, in which BPA binds to nuclear ERα or Erß, or through nongenomic signaling by binding to membrane ERs, prompting a rapid and intense response. With daily and constant exposure, BPA's tendency to bioaccumulate and its ability to activate nongenomic signaling pathways can alter women's metabolic and reproductive function, leading to hyperandrogenism, insulin resistance, obesity, atherogenic dyslipidemia, chronic inflammatory state, and anovulation and favoring PCOS. The harmful changes caused by BPA can be passed on to future generations without the need for additional exposure because of epigenetic modifications. Not only high BPA levels can produce harmful effects, but at low levels, BPA may be harmful when exposure occurs during the most vulnerable periods, such as the fetal and neonatal periods, as well as during the prepubertal age causing an early accumulation of BPA in the body. Learning how BPA participates in the pathogenesis of PCOS poses a challenge and further studies should be conducted.

RESUMO

BACKGROUND: Polycystic ovarian syndrome (PCOS) is one of the most common endocrine disorders in women of reproductive age. In Mexico, its prevalence in patients with type 1 diabetes (T1D) is unknown. AIM: To evaluate the clinical and biochemical characteristics of patients with T1D with and without PCOS. METHODS: A cross-sectional study was conducted to evaluate women of reproductive age with T1D for the diagnosis of PCOS using the criteria of the European Society for Human Reproduction and Embryology/American Society for Reproductive Medicine. Clinical information was obtained from clinical records, and we recorded anthropometric variables and performed a laboratory test during the follicular phase. The estimated glucose disposal rate and visceral adiposity index were also calculated to assess insulin resistance. Subsequently, participants were evaluated based on the presence or absence of PCOS. RESULTS: Thirty-nine percent of patients with T1D had PCOS. The most frequent components of PCOS were polycystic ovary morphology (58.5%), clinical hyperandrogenism (41.5%), oligomenorrhea (29.2%), and biochemical hyperandrogenism (19.5%). Patients with PCOS used more insulin per day (1.04 ± 0.33 vs. 0.71 ± 0.29 IU/kg/d, p = 0.003), had lower fasting glucose (116.4 ± 59.79 vs. 161.16 ± 63.9 mg/dl, p = 0.029) and higher right ovarian volume (11.36 [8.64-15.89] vs. 6.9 [5.55-8.77] cm3, p = 0.005) and Ferriman-Gallwey scores (9.06 ± 2.05 vs. 7.12 ± 3.15 points, p = 0.035) compared to patients without PCOS. The frequency of insulin resistance and metabolic syndrome in women with PCOS was 37.5 and 18.8%, respectively. CONCLUSION: PCOS is a very heterogeneous entity, with a high frequency in women with T1D.

RESUMO

Polycystic ovary syndrome (PCOS) affects around 10% of women in the reproductive age group and is characterized by ovulatory dysfunction, hyperandrogenism, and/or polycystic ovarian morphology. PCOS is highly associated with metabolic-associated fatty liver disease (MAFLD) as both diseases share common risk factors. At the time of diagnosis of PCOS, screening for MAFLD is necessary because most patients with MAFLD are asymptomatic. The importance of early detection of MAFLD in patients with PCOS is that a timely intervention in patients with steatosis or steatohepatitis can reduce the probability of liver disease progression.

RESUMO

OBJECTIVE: The aim of this study was to analyze the association between lower urinary tract symptoms and polycystic ovary syndrome. METHODS: A total of 180 women were enrolled in this prospective study. Demographic data, body mass index, waist circumference, modified Ferriman-Gallwey scores, biochemical parameters, ultrasonographic findings, and maximum urinary flow rate (Q max) were analyzed. In addition, the Beck Depression Inventory, Beck Anxiety Inventory, and Bristol Female Lower Urinary Tract Symptom Scored Form questionnaires were evaluated for each subject. RESULTS: The mean age of patients was calculated as 23.78±3.04 years, which was similar for both groups (p=0.340). Body mass index, waist circumference, Beck Depression Inventory, Beck Anxiety Inventory, Bristol Female Lower Urinary Tract Symptom Scored Form, and modified Ferriman-Gallwey scores were significantly higher in group 2 (p<<0.001). Hyperandrogenism, lipid profile, and glucose metabolism disorders were more frequent in group 2 (p<<0.05). Bladder capacity (Q max), bladder wall thickness, and post-void residual volume values were similar in both groups (p>>0.05). CONCLUSION: In our study, a close relationship was observed between polycystic ovary syndrome and lower urinary tract symptoms. In this context, we think that a detailed urinary system evaluation of women with polycystic ovary syndrome is extremely important.

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).
