RESUMO

BACKGROUND: Polycystic ovary syndrome (PCOS) is a heterogenous endocrine condition and combined oral contraceptives (COCs) have been demonstrated to be the first-line treatment to women who do not intend to become pregnant. The combination of COCs and PCOS may or may not amplify the risks of cardiovascular events. OBJECTIVE: To investigate whether surrogates for obesity may be influenced by the use of COCs containing different formulations in women with PCOS. METHOD: From January 2024 a literature search was conducted in Google Scholar and Pubmed databases using PCOS, COC, and obesity terms. Hand search of randomized clinical trials in the references of obtained manuscripts was also performed. After the exclusion of reviews and articles that did not fulfill eligibility criteria, compared the results obtained before and after the use of COCs in 13 randomized clinical trials (RCTs). Random-effects model was used to estimate the standardized mean differences (SMD) and standard errors (SE). Risk of bias was examined using the Rob2 tool. RESULT: Thirteen heterogeneous RCTs reported no difference in waist circumference with the use of different COC formulations (p = 0.714). On the contrary, body fat mass increased with the use of pill (p = 0.013). Waist triglyceride index and lipid accumulation product tended to be higher after the use of COCs (p = 0.073 and p = 0.064, respectively). CONCLUSION: Combined oral contraceptives with different formulations might increase fat mass accumulation in women with PCOS. Lipids may also be increased in PCOS users. Because some concerns about the quality and heterogeneity identified in various RCTs, caution should be taken before a definitive conclusion regarding the use of COCs and obesity.

RESUMO

Esta revisión narrativa explora el papel potencial del estetrol (E4), un esteroide estrogénico natural, en la anticoncepción, analizando sus propiedades farmacológicas, su efectividad y su seguridad. Se revisaron estudios preclínicos, ensayos clínicos y evaluaciones de seguridad del E4 como anticonceptivo oral combinado (AOC). Se investigó el impacto en parámetros endocrinos, metabólicos y hemostáticos, así como su tolerabilidad. En los resultados, el E4 tiene menor afinidad por el receptor de estrógeno-α de membrana, pero mantiene la actividad agonista en los receptores nucleares. E4/DRSP (drospirenona) demostró ser un AOC eficaz, con ciclos de sangrado regulares y predecibles en la mayoría de las mujeres. La tolerabilidad fue favorable, con eventos adversos leves o moderados y bajas tasas de interrupción. El sangrado fue el evento adverso más común, y se reportaron casos raros de migrañas con aura, trombosis venosa profunda, hiperpotasemia y depresión. E4/DRSP tuvo mínimo impacto en los parámetros lipídicos, hepáticos, de globulina fijadora de hormonas sexuales y de metabolismo de hidratos de carbono, y efecto neutral o mínimo en los parámetros hemostáticos. Se concluye que E4/DRSP parece ser una opción anticonceptiva eficaz y segura, con reducido riesgo trombótico y mínimo impacto en los parámetros endocrinos y metabólicos. Se requiere más investigación para confirmar su seguridad y eficacia a largo plazo.

This narrative review explores the potential role of estetrol (E4), a natural estrogenic steroid, in contraception, analyzing its pharmacological properties, effectiveness, and safety. Preclinical studies, clinical trials, and safety assessments of E4/DRSP (drospirenone) as a combined oral contraceptive (COC) were reviewed. The impact on endocrine, metabolic, and hemostatic parameters, as well as tolerability, was investigated. In results, E4 exhibits lower affinity for estrogen transmembrane receptor-α but maintains agonistic activity on nuclear receptors. E4/DRSP proved to be an effective COC with regular and predictable bleeding cycles in most women. Tolerability was favorable with mild or moderate adverse events and low discontinuation rates. Bleeding was the most common adverse event, and rare cases of aura migraines, deep vein thrombosis, hyperkalemia, and depression were reported. E4/DRSP had minimal impact on lipid, hepatic, sex hormone-binding globulin, and carbohydrate metabolism parameters, with a neutral or minimal effect on hemostatic parameters. The conclusion is that E4/DRSP seems to be an effective and safe contraceptive option, with reduced thrombotic risk and minimal impact on endocrine and metabolic parameters. Further research is needed to confirm long-term safety and efficacy.

RESUMO

As pílulas anticoncepcionais consistem na formulação combinada de um estrogênio e um progestagênio ou em apresentações simples de progestagênio isolado com a finalidade de bloquear a ovulação e alterar as condições do útero e das tubas uterinas, bloqueando parcialmente a foliculogênese e a inibição do pico de gonadotrofinas. Desse modo, no que concerne à temática, diversas publicações na mídia de ampla divulgação afirmam que os anticoncepcionais orais têm papel importante na sarcopenia e na hipotrofia, incluindo perda de força muscular e redução do desempenho físico. Assim, o presente trabalho tem por objetivo avaliar, por meio de pesquisas de artigos, a correlação entre anticoncepcionais hormonais orais e hipotrofia muscular. Foi concluído que os artigos científicos especializados no tema são ainda bastante inconclusivos, sugerindo que há indicações de que usuárias de anticoncepcional oral sejam mais suscetíveis ao dano muscular induzido por exercícios, contudo ainda não há consenso.

Anticonception pills consist of a combined formulation of an estrogen and a progestogen or simple presentations of progestogen alone with the purpose of blocking ovulation and altering the conditions of the uterus and uterine tubes, partially blocking folliculogenesis and inhibiting the gonadotropin peak. Thus, with regard to the subject, several widely publicized media publications claim that oral contraceptives play an important role in sarcopenia and hypotrophy, including loss of muscle strength and reduced physical performance. So, the present work aims to evaluate through article searches the correlation between oral hormonal contraceptives and muscle hypotrophy. It was concluded that scientific articles specialized on the subject are still quite inconclusive, suggesting that there are indications that oral contraceptive users are more susceptible to exercise-induced muscle damage, however there is still no consensus.

RESUMO

SUMMARY OBJECTIVE: The aim of this study was to carry out a systematic review of the literature with meta-analysis to evaluate the effect of using oral contraceptive and hormone replacement therapy as a protective factor in the formation of intracranial aneurysms and subarachnoid hemorrhage. METHODS: This is a systematic review of the literature with meta-analysis, using PubMed and Embase as databases and the PRISMA method. Case-control and cohort studies published until December 2022 were included in this review. RESULTS: Four studies were included in this review; three of which were eligible for meta-analysis. Regarding the use of oral contraceptive and the development of subarachnoid hemorrhage, there was a lower risk of aneurysm rupture with an odds ratio 0.65 (confidence interval 0.5-0.85). In the analysis of patients using hormone replacement therapy and developing subarachnoid hemorrhage, there was also a lower risk of aneurysm rupture with an OR 0.54 (CI 0.39-0.74). Only one article analyzed the formation of intracranial aneurysm and the use of hormone replacement therapy and oral contraceptive, and there was a protective effect with the use of these medications. oral contraceptive: OR 2.1 (CI 1.2-3.8) and hormone replacement therapy: OR 3.1 (CI 1.5-6.2). CONCLUSION: The use of hormone replacement therapy and oral contraceptive has a protective effect in intracranial aneurysm rupture and formation.

RESUMO

Objetivo: Investigar o conhecimento das adolescentes atendidas no Ambulatório de Ginecologia sobre os métodos contraceptivos. Métodos: Foi realizado um estudo quantitativo de corte transversal com adolescentes do sexo feminino, acompanhadas no Serviço de Ginecologia. A seleção foi por ordem de chegada mediante agendamento prévio. Após consulta médica, foi aplicado um questionário anônimo e estruturado sobre: características sociodemográficas; antecedentes ginecológicos; conhecimento do uso correto e indicação dos métodos contraceptivos. As variáveis foram analisadas pela estatística descritiva com medidas de tendência central e variabilidade. A pesquisa foi aprovada pelo Comitê de Ética em Pesquisa. Resultados: A população estudada foi composta por adolescentes com média de idade de 15,80 anos (+/- 1,3), 48,0% de etnia/cor parda, 84,0% frequentavam a escola pública e 56,0% cursavam o ensino médio. A maioria possuía conhecimento insuficiente/ausência de conhecimento e 80,0% tinham informações sobre contracepção que não envolveu a participação de um profissional de saúde, apesar de eles indicarem o uso dos métodos para a maioria dessas jovens (75,0%). A combinação do preservativo masculino e anticoncepcional oral foi referida em 25,0% das adolescentes. Conclusão: A maioria das adolescentes possuía conhecimento insuficiente/ausente sobre métodos contraceptivos, o que parece contribuir para o uso inconsistente deles. A maior prevalência do uso do preservativo masculino e do anticoncepcional oral associada à baixa participação dos profissionais de saúde como fonte de informação para o uso correto dos métodos ratifica a necessidade de políticas públicas sobre educação sexual para que as adolescentes exerçam sua sexualidade com responsabilidade e segurança.(AU)

Objective: Evaluate the knowledge of adolescents seen in the Gynecology Outpatient Clinic for Children and Youth. Methods: A quantitative transverse study was carried out with thems, regularly seen at the Gynecology Outpatient Clinic for Children and Youth. We selected participants by arrival order. After having their appointment done, we applied an anonymous and structured questionnaire containing questions regarding sociodemographics characteristics, past gynaecological history and knowledge, correct use and indications of contraceptives methods. Those variables were analysed using descriptive statistics such as central tendency and variability. The research was approved by the Ethics in Research Committee. Results: The population studied was composed of adolescents with an average age of 15.8 years (+/- 1.3), 48.0% of ethnicity/brown colour, 84.0% attended public school and 56.0% were in high school. Most of them had insufficient knowledge/lack of knowledge and 80.0% had information about contraception that did not involve the participation of a health professional, however health professionals had suggested a method of contraception for most of these young women (75.0%). The combination of male condoms and oral contraceptives were reported by 25.0% of adolescents. Conclusion: That most of the adolescents had insufficient/absent knowledge about contraceptive methods which seems to contribute to their inconsistent use. The high prevalence of the use of male condoms and oral contraceptives found in this study and low participation of health professionals as a source of information for the correct use of methods ratify the need for public policies on sex education for adolescents enjoy their sexuality responsibly and safely.(AU)

RESUMO

ABSTRACT Objectives: To assess factors associated with post-abortion contraceptive discontinuation. Method: This cross-sectional study addressed 111 women aged 18-49 attending Primary Health Care Facilities in São Paulo/SP, Aracaju/SE, and Cuiabá/MT, Brazil, who reported an abortion five years before the interview held in 2015-2017. Kaplan-Meier estimates and Cox Regression were used for data analysis. Results: Oral hormonal contraceptives, male condoms, and injectable contraceptives were the methods most frequently used. The contraceptive discontinuation rate was 41.8% in the 12 months after the abortion. The pill was the method most frequently abandoned (58.3%); male condoms were the method that failed the most (72.7%), and injectable contraceptives were the method most frequently switched (50.0%). Being up to 24 years old, having ten or more years of education, having three or more children, and a desire to wait longer before becoming pregnant again were associated with post-abortion contraceptive discontinuation. Conclusion: Short-acting contraceptive methods were predominant among post-abortion women. The type of discontinuation varied according to the type of method used. The factors associated with contraceptive discontinuation were age, education, parity, and reproductive intention.

RESUMEN Objetivos: Analizar los factores asociados a la discontinuidad en el uso de métodos anticonceptivos después de un aborto. Método: Estudio transversal realizado con 111 mujeres de 18 a 49 años, usuarias de Unidades Básicas de Salud de São Paulo/SP, Aracaju/SE y Cuiabá/MT, quienes reportaron aborto en los cinco años previos a la entrevista realizada entre 2015-2017. Se utilizó Kaplan-Meier y la regresión de Cox para el análisis de datos. Resultados: Tras el aborto, los métodos utilizados se centraron en los de corta duración: anticonceptivos hormonales orales, condones masculinos e inyectables. La tasa de discontinuidad en el uso de métodos anticonceptivos fue del 41,8% en los 12 meses posteriores al aborto. La píldora fue el método que se abandonó con más frecuencia (58,3%); el condón masculino en el que ocurrieron más fallas (72,7%); e inyectables intercambiados con mayor frecuencia (50,0%). Tener 24 años o más, 10 o más años de escolaridad, alta paridad (3 o más) y desear esperar para quedar embarazada se asociaron con la discontinuidad en el uso de métodos anticonceptivos después del aborto. Conclusión: Las mujeres después de un aborto utilizaron predominantemente métodos anticonceptivos de corta duración, que con mayor frecuencia se suspenden. El tipo de discontinuidad, abandono, intercambio o falla varió según el tipo de método utilizado. La edad, la educación, la paridad y la intención reproductiva se asociaron con la discontinuidad en el uso de métodos anticonceptivos después del aborto.

RESUMO Objetivos: Analisar os fatores associados à descontinuidade no uso de método contraceptivos após a vivência de um abortamento. Método: Estudo transversal, conduzido com 111 mulheres de 18-49 anos, usuárias de Unidades Básicas de Saúde de São Paulo/SP, Aracaju/SE e Cuiabá/MT, que relataram abortamento nos cinco anos anteriores às entrevistas realizadas entre 2015-2017. Utilizou-se Kaplan-Meier e regressão de Cox para análise dos dados. Resultados: Os métodos mais utilizados foram o contraceptivo hormonal oral, preservativo masculino e injetáveis. A taxa de descontinuidade contraceptiva foi 41,8% nos 12 meses. A pílula foi o método mais abandonado (58,3%); o preservativo masculino aquele que mais falhou (72,7%); e injetáveis os mais trocados (50,0%). Ter até 24 anos de idade, mais de 10 anos de escolaridade, três ou mais filhos e querer esperar mais para engravidar associaram-se a descontinuar o uso dos métodos contraceptivos após o abortamento. Conclusão: Após o abortamento, as mulheres usaram predominantemente métodos contraceptivos de curta duração. O tipo de descontinuidade, abandono, troca ou falha, variou conforme o método usado. Os fatores associados à descontinuidade contraceptiva foram a idade, a escolaridade, a paridade e a intenção reprodutiva.

RESUMO

This study evaluated such as exposure to ethinylestradiol during the prenatal (18th-22nd day) and pubertal (42nd-49th day) periods acts on the male ventral prostate and female prostate of 12-month old gerbils. We performed the analysis to serum hormone levels for estradiol and testosterone. The prostates were submitted to morphometric and immunohistochemical analyses. Exposure to ethinylestradiol during these developmental periods decreased the testosterone serum levels in males and increased the estradiol serum levels in females. Morphologically, prostate intraepithelial neoplasia and disorders in the arrangement of the fibrous components were observed in the prostate glands of both sexes of gerbil exposed to ethinylestradiol during development periods. In the male prostate, the ethinylestradiol promoted decreased in the frequency of positive epithelial cell for androgen receptor (AR) and increased the frequency of positive stromal cell for estrogen receptor α. However, in the female prostate, this synthetic estrogen caused AR upregulation and increased cell proliferation. This study shows that the exposure to ethinylestradiol during development phases alters the morphology and the hormonal signaling in the male and female prostates of old gerbils, confirming the action of ethinylestradiol as endocrine disruptor.

RESUMO

BACKGROUND: Most patients undergoing Roux-en-Y gastric bypass (RYGB) are women in reproductive age. It is not known if bariatric surgery affects the pharmacokinetics of oral contraceptives. OBJECTIVES: The primary objective was to evaluate ethinylestradiol (EE) and levonorgestrel (LNG) absorption in women undergoing RYGB, compared with nonoperated controls matched by age and body mass index (BMI). A secondary objective was to assess whether the time since surgery and BMI in the postoperative period influenced the absorption parameters. SETTING: University hospital, Brazil. METHODS: This study was designed to compare the maximum plasma concentration (Cmax), the time to the peak plasma level (Tmax), the area under the curve (AUC0-8 and AUC0-∞) after a single dose of a combined oral contraceptive with 0.03 mg EE and 0.15 mg LNG among 20 women after RYGB and 20 controls. Blood samples were obtained for 8 hours. RESULTS: The mean LNG AUC0-8 and LNG AUC0-∞ were higher in RYGB group (P = .048 and P = .004, respectively). We found a positive correlation for LNG AUC0-8 (P = .045) and AUC0-∞ (P = .004) and the time since surgery, and we found a negative correlation for LNG Cmax (P = .018), AUC0-8 (P = .003), and AUC0-∞ (P = .001) and BMI. CONCLUSION: No significant differences were found in oral EE pharmacokinetics. The operated group showed higher mean LNG AUC0-8 and AUC0-∞ but it was not considered clinically significant. The present study suggests that RYGB may not affect EE and LNG absorption.

RESUMO

BACKGROUND: The venous thromboembolism (VTE) is a frequent condition, which may worsen the prognosis of hospitalized COVID-19 patients. Nevertheless, the incidence of this complication is unknown in patients with mild COVID-19 symptoms. CASE SUMMARY: A 26-year-old female nurse, who had been taking oral contraceptive pills (OCPs) treatment for the last 2 years, developed mild COVID-19 symptoms (rhinitis and anosmia). She underwent isolation at home and was subsequently followed up with telehealth visits. Fifteen days after her initial presentation, she developed acute onset sudden dyspnoea. On physical examination, she was found to be tachycardic with normal pulse oximetry. The initial risk score for VTE was moderate and laboratory results showed increased D-dimer level without other relevant findings. Computed tomography pulmonary angiography was performed, which confirmed low-risk subsegmental pulmonary embolism. DISCUSSION: Venous thromboembolism in patients who present with severe COVID-19 symptoms has already been described in the literature; its incidence is greater in patients hospitalized in intensive care units. Efforts to prevent VTE based on risk scores are widely recognized. However, the relationship in patients who present with mild COVID-19 symptoms and VTE is still unknown. Recently, experts on this field have introduced thromboprophylaxis guidelines including ambulatory patients based on the severity of COVID-19 symptoms and pro-thrombotic risk. Our patient showed no major risk for developing VTE; therefore, the VTE could be associated with SARS-CoV-2 infection or the eventual pro-thrombotic association with the concomitant use of OCPs.

RESUMO

Objetivo: Avaliar o perfil e os fatores associados ao uso de anticoncepcionais orais combinados (AOC) em regimes de pausa (intermitente) ou estendido (contínuo) em mulheres férteis atendidas em um centro de planejamento familiar. Métodos: Trata-se de um estudo transversal, realizado no Centro de Pesquisa e Assistência em Reprodução Humana (CEPARH), Salvador, Bahia. Resultados: Entre julho e setembro de 2017, 210 mulheres atendidas, consecutivamente, no CEPARH foram entrevistadas. Dessas, 69 (32,8%) fazem uso de algum AOC, das quais 32 (46,4%) utilizam-no em regimes estendidos. Mulheres que trabalham têm 1,89 vezes mais chances de usarem AOC do que as que não trabalham (IC95%: 1,04-3,42; p=0,039). Nenhuma diferença significativa foi observada nas características entre as que fazem uso de AOC em regime de pausa ou estendido (p>0,05). Conclusão: Os resultados indicam que mulheres que trabalham adiam a concepção e utilizam com mais frequência a pílula contraceptiva, independentemente da forma de administração (forma contínua ou intermitente). Ademais, não há nenhum fator que contribua, significativamente, para que as mulheres façam uso estendido das cartelas de AOC.

Objective To evaluate the profile and factors associated with the use of combined oral contraceptives (COC) in pause (intermittent) or extended (continuous) regimens in fertile women attended at a family planning center. Methods: This is a cross-sectional study, carried out at the Center for Research and Assistance in Human Reproduction (CEPARH), Salvador, Bahia. Results: Between July and September 2017, 210 women consecutively attended at CEPARH were interviewed. Of these, 69 (32.8%) make use of some COC, of which 32 (46.4%) use it in extended regimens. Women who work were 1.89 times more likely to use COC than those who do not work (95%CI: 1.04-3.42; p=0.039). No significant difference was observed in characteristics among those who use COC in a paused or extended regime (p>0.05). Conclusion: The results indicate that working women postpone conception and use the contraceptive pill more frequently, regardless of the form of administration (continuous or intermittent). Moreover, there is no factor that contributes, significantly, for women to make extended use of COC cards.
