Cardiovascular Risk Factors in Premature Ovarian Insufficiency using Hormonal Therapy / Fatores de risco cardiovascular na insuficiência ovariana prematura em uso de terapia hormonal

Abstract Objective Premature ovarian insufficiency (POI) is characterized by early hypoestrogenism. An increased risk of cardiovascular (CV) disease is a long-term consequence of POI. A challenge of hormone therapy (HT) is to reduce the CV risk. Methods Cross-sectional study with lipid profile analysis (total cholesterol, LDL-C, HDL-C, VLDL-C and triglycerides), blood glucose levels and arterial blood pressure of women with POI using HT, compared with age and BMI-matched women with normal ovarian function (controls). Results The mean age and BMI of 102 POI patients using HT and 102 controls were 37.2 ± 6.0 and 37.3 ± 5.9 years, respectively; 27.0 ± 5.2 and 27.1 ± 5.4 kg/m2. There wasn't difference between groups in arterial systolic and diastolic blood pressure, blood glucose levels, total cholesterol, LDL-C, VLDL-C and triglycerides. HDL-C levels were significantly higher in the POI group (56.3 ± 14.6 and 52 ± 13.9mg/dL; p = 0.03). Arterial hypertension was the most prevalent chronic disease (12% in the POI group, 19% in the control group, p = ns), followed by dyslipidemia (6 and 5%, in POI and control women). Conclusion Women with POI using HT have blood pressure levels, lipid and glycemic profile and prevalence of hypertension and dyslipidemia similar to women of the same age and BMI with preserved gonadal function, in addition to better HDL levels.

Resumo Objetivo A insuficiência ovariana prematura (IOP) é caracterizada pelo hipoestrogenismo precoce. Risco aumentado de doença cardiovascular (CV) é uma consequência a longo prazo da IOP e um desafio da terapia hormonal (TH) é reduzir o risco CV. Métodos Estudo transversal com análise do perfil lipídico (colesterol total, LDL-C, HDL-C, VLDL-C e triglicerídeos), glicemia e pressão arterial de mulheres com IOP em uso de TH, em comparação a mulheres com função ovariana normal (controles) pareadas por idade e IMC. Resultados A média de idade e IMC de 102 pacientes com IOP em uso de TH e 102 controles foi de 37,2 ± 6,0 e 37,3 ± 5,9 anos, respectivamente; 27,0 ± 5,2 e 27,1 ± 5,4 kg/m2. Não houve diferença entre os grupos na pressão arterial sistólica e diastólica, glicemia, colesterol total, LDL-C, VLDL-C e triglicerídeos. Os níveis de HDL-C foram significativamente maiores no grupo IOP (56,3 ± 14,6 e 52 ± 13,9mg/dL; p = 0,03). A hipertensão arterial foi a doença crônica mais prevalente (12% no grupo POI, 19% no grupo controle, p = ns), seguida da dislipidemia (6 e 5%, no grupo POI e controle). Conclusão Mulheres com IOP em uso de TH apresentam níveis pressóricos, perfil lipídico e glicêmico e prevalência de hipertensão e dislipidemia semelhantes às mulheres da mesma idade e IMC com função gonadal preservada, além de melhores níveis de HDL.

Mechanism of tonifying kidney and activating blood therapy for premature ovarian failure:a review / 中国中药杂志

Healthy birth and child development are the prerequisite for improving the overall quality of the population. However, premature ovarian failure(POF) threatens the reproductive health of women. The incidence of this disease has been on the rise, and it tends to occur in the young. The causes are complex, involving genetics, autoimmune, infectious and iatrogenic factors, but most of the causes remain unclear. At the moment, hormone replacement therapy and assisted reproductive technology are the main clinical approaches. According to traditional Chinese medicine(TCM), kidney deficiency and blood stasis are one of the major causes of POF, and TCM with the effects of tonifying kidney and activating blood has a definite effect. Through clinical trials, TCM prescriptions for POF have excellent therapeutic effect as a result of multi-target regulation and slight toxicity. In particular, they have no obvious side effects. A large number of studies have shown that the kidney-tonifying and blood-activating TCM can regulate the neuroendocrine function of hypothalamic-pituitary-ovarian axis, improve ovarian hemodynamics and microcirculation, reduce the apoptosis of granulosa cells, alleviate oxidative stress injury, and modulate immunologic balance. The mechanism is that it regulates the phosphatidylinositol 3-kinase(PI3K)/protein kinase B(Akt), vascular endothelial growth factor(VEGF), transforming growth factor(TGF)-β/Smads, nuclear factor E2-related factor 2(Nrf2)/antioxidant response element(ARE), and nuclear factor-kappa B(NF-κB) signaling pathways. This article summarized the pathological mechanisms of tonifying kidney and activating blood TCM in the prevention and treatment of POF and explored the biological basis of its multi-pathway and multi-target characteristics in the treatment of this disease. As a result, this study is expected to serve as a reference for the treatment of POF with the tonifying kidney and activating blood therapy.

Mechanism of Qiwei Guibao Granules in treatment of premature ovarian failure based on proteomics / 中国中药杂志

In this study, the underlying mechanism of Qiwei Guibao Granules(QWGB) in the treatment of premature ovarian fai-lure(POF) was explored by the proteomics technique. Firstly, the POF model was induced in mice by intragastric administration of Tripterygium wilfordii glycosides solution at 50 mg·kg~(-1) for 14 days. Ten days prior to the end of the modeling, the estrous cycle of mice was observed every day to evaluate the success of modeling. From the 1st day after modeling, the POF model mice were treated with QWGB by gavage every day and the treatment lasted four weeks. On the 2nd day after the end of the experiment, blood was collected from the eyeballs and the serum was separated by centrifugation. The ovaries and uterus were collected and the adipose tissues were carefully stripped. The organ indexes of the ovaries and uterus of each group were calculated. The serum estrogen(E_2) level of mice in each group was detected by ELISA. Protein samples were extracted from ovarian tissues of mice, and the differential proteins before and after QWGB intervention and before and after modeling were analyzed by quantitative proteomics using tandem mass tags(TMT). As revealed by the analysis of differential proteins, QWGB could regulate 26 differentially expressed proteins related to the POF model induced by T. wilfordii glycosides, including S100A4, STAR, adrenodoxin oxidoreductase, XAF1, and PBXIP1. GO enrichment results showed that the 26 differential proteins were mainly enriched in biological processes and cellular components. The results of KEGG enrichment showed that those differential proteins were involved in signaling pathways such as completion and coalescence cascades, focal adhesion, arginine biosynthesis, and terpenoid backbone biosynthesis. The complement and coalescence cascades signaling pathway was presumably the target pathway of QWGB in the treatment of POF. In this study, the proteomics technique was used to screen the differential proteins of QWGB in the treatment of POF in mice induced by T. wilfordii glycosides, and they were mainly involved in immune regulation, apoptosis regulation, complement and coagulation cascade reactions, cholesterol metabolism, and steroid hormone production, which may be the main mechanisms of QWGB in the treatment of POF.

Fecal incontinence or pelvic organ prolapse among women with premature ovarian insufficiency

Objectives: To assess the status of the pelvic floor muscle (PFM) of premature ovarian insufficiency women (POI women) and the incidence of fecal incontinence (FI) and pelvic organ prolapse (POP). Methods: A secondary analysis of a cross-sectional study with 150 women with POI was performed. Pelvic floor muscle assessment was performed with the PERFECT scale. The subscales POPDI-6 and CRADI-8 of the questionnaire Pelvic Floor Distress Inventory-20 (PFDI-20) were used for pelvic floor symptoms focused on FI and POP. Moreover, FI and POP were also assessed as dichotomous variables (yes/no). Results: Women with FI and POP did not present differences in the PFM assessment across P (p = 0.61), E (p = 0.78), R (p = 0.22), and F (p = 0.79) variables when compared with women with POI; no differences were also seen between women with and without POP according the pelvic muscles: P (p = 0.91), E (p = 0.99), R (p = 0.62), and F (p = 0.10). Women with FI and POP presented higher scores in all PFDI-20 subscales and total score when compared with the control group (p < 0.05). Conclusions Pelvic floor muscle assessment within POI women with or without FI or POP did not differ. However, PF symptoms are more severe in the FI or POP groups. (AU)

Effect of acupuncture at "Zhibian" (BL 54) through "Shuidao" (ST 28) on the expression of apoptosis-related factors in rats with premature ovarian insufficiency based on oxidative stress / 中国针灸

OBJECTIVE@#To explore the possible mechanism of acupuncture at "Zhibian" (BL 54) through "Shuidao" (ST 28) on premature ovarian insufficiency (POI) from the perspective of oxidative stress.@*METHODS@#Sixty female SD rats were randomly divided into a blank group, a model group, a sham acupuncture group, a medication group, and an acupuncture group, 12 rats in each group. Except the blank group, the rats in the remaining groups were intraperitoneally injected with cyclophosphamide to establish the POI model. After the model was successfully established, the rats in the acupuncture group were treated with acupuncture at "Zhibian" (BL 54) through "Shuidao" (ST 28), with a depth of about 12 mm, and the needle was retained for 30 min; the acupuncture was given once a day, for a total of 4 weeks. The rats in the sham acupuncture group were treated with blunt-head needle to tap the skin surface of "Zhibian" (BL 54), without penetrating the skin, once a day for 4 weeks. The rats in the medication group were treated with estradiol valerate by gastric gavage for 4 weeks. After the intervention, the level of reactive oxygen species (ROS) in the ovarian tissue was detected by fluorescence probe; the expression of c-Jun N-terminal kinase (JNK), forkhead box O1 (FoxO1), tumor suppressor gene protein 53 (p53) and p53 up-regulated modulator of apoptosis (Puma) mRNA and protein in ovarian tissue were detected by real-time fluorescence quantitative PCR and Western blot.@*RESULTS@#Compared with the blank group, the level of ROS and the expression of JNK mRNA, p-JNK protein, FoxO1, p53, Puma mRNA and protein in the ovarian tissue in the model group were increased (P<0.01). Compared with the model group, the level of ROS and the expression of p-JNK protein, FoxO1, p53, Puma mRNA and protein in the ovarian tissue in the sham acupuncture group were slightly reduced, but the difference was not statistically significant (P>0.05). The level of ROS and the expression of JNK mRNA, p-JNK protein, FoxO1, p53, Puma mRNA and protein in the ovarian tissue in the acupuncture group and the medication group were reduced (P<0.01).@*CONCLUSION@#Acupuncture at "Zhibian" (BL 54) through "Shuidao" (ST 28) could improve the level of oxidative stress, down-regulate the expression of apoptosis-related factors JNK, FoxO1, p53 and Puma induced by oxidative stress, and inhibit the premature failure of ovarian reserve function caused by apoptosis of ovarian granulosa cells in POI rats.

Practical Prediction Model for Ovarian Insufficiency after Radiation / Modelo prático de predição para insuficiência ovariana após radiação

Abstract Objective The present study aimed to develop a useful mathematical model that predicts the age at which premature ovarian insufficiency might occur after teletherapy radiation. A diagnosis of premature or early menopause has physical and psychological consequences, so women may need support and long-term medical follow-up. Methods To correlate ovarian radiation dose with ovarian function, we used the formula described by Wallace et al.: √g(z) = 10(2-0,15z), where "g(z)" and "z" represent oocyte survival rate and the radiation dose (in Gray), respectively. By simulating different ages and doses, we observed a pattern that could be used to simplify the relationship between radiation dose and remaining time of ovarian function. Results We obtained a linear function between ovarian radiation dose and loss of ovarian function (LOF) that is the percentage of decrease in the time to the ovarian failure compared with the time expected for a woman at the same age without irradiation exposition. For patients <40 years old and with ovarian radiation doses < 5 Gy, the equation LOF = 2.70 + (11.08 × Dose) can be applied to estimate the decrease in time to premature ovarian insufficiency. Conclusion The present study reports a practicable theoretical method to estimate the loss of ovarian function. These findings can potentially improve the management and counseling of young women patients submitted to radiotherapy during their reproductive years.

Resumo Objetivo O presente estudo teve como objetivo desenvolver um modelo matemático útil que prediz a idade na qual a insuficiência ovariana prematura pode ocorrer após a radioterapia externa (teleterapia). O diagnóstico de menopausa prematura ou precoce tem consequências físicas e psicológicas; portanto, as mulheres podem precisar de apoio e acompanhamento médico de longo prazo. Métodos Para correlacionar a dose de radiação ovariana com a função ovariana, foi usada a fórmula descrita por Wallace et al.: √g(z) = 10(2-0,15z), na qual "g(z)" e "z" representam a taxa de sobrevivência do oócito e a dose de radiação (em Gray), respectivamente. Ao simular diferentes idades e doses, observamos um padrão que poderia ser usado para simplificar a relação entre a dose de radiação e o tempo restante da função ovariana. Resultados Obtivemos uma função linear entre a dose de radiação ovariana e a perda da função ovariana (LOF, na sigla em inglês) que é a porcentagem de diminuição no tempo até a falência ovariana em relação ao tempo esperado para uma mulher da mesma idade sem exposição à radiação. Para pacientes<40 anos de idade e com doses de radiação ovariana < 5 Gy, a equação LOF = 2,70 + (11,08 × Dose) pode ser aplicada para estimar a redução no tempo até a insuficiência ovariana. Conclusão O presente estudo relata um método teórico viável para estimar a perda da função ovariana. Estes achados podem melhorar potencialmente o manejo e o aconselhamento de pacientes jovens submetidas à radioterapia durante seus anos reprodutivos.

FMR1 alleles in women with idiopathic infertility / Alelos do gene FMR1 em mulheres com infertilidade idiopática

INTRODUCTION: The frequency of the premutation alleles of the FMR1 gene varies from 1:100 to 1:260 Israeli, Canadian, Finnish and American women, but it is unknown in Brazil. Premutation carriers may have reduced reproductive age and are at risk of transmitting the expanded allele to their offspring, and consequently fragile X syndrome. OBJECTIVE: To observe the distribution range of the FMR1 gene alleles in a population of women with idiopathic infertility, without symptoms of premature ovarian insufficiency. METHODS: The presence of premutation in FMR1 was assessed by conventional PCR, agarose, and acrylamide gel and analysis of fragments in capillary electrophoresis. Lymphocyte DNA obtained from 283 women undergoing infertility treatment was analyzed. RESULTS: 169 patients had the normal heterozygous allele (59.7%), 114 had the normal homozygous allele (40.6%) and no patient had the premutation. Premature ovarian insufficiency is seen in 20 to 30% of women with the permutated allele. Thus, the condition can be asymptomatic in a large part of the premutation carriers. Brazil has a diverse population and, therefore, the allele frequencies of many gene variants are unknown. Previous Brazilian studies have shown a low frequency of the premutation allele in different patient cohorts. Corroborating these articles, the results demonstrated that the frequency of the premutation allele is low in the infertile women population studied. CONCLUSION: Tracking the size of the FMR1 gene alleles allows the expansion of knowledge about the frequency of risk alleles associated with genetic diseases in the Brazilian population.

INTRODUÇÃO: A frequência dos alelos pré-mutados do gene FMR1 varia de 1:100 e 1:260 mulheres israelenses, canadenses, finlandesas e americanas, mas é desconhecida no Brasil. Portadoras da pré-mutação podem apresentar redução da idade reprodutiva e possuem risco de transmissão do alelo expandido para a prole, e consequentemente a Síndrome do X frágil. OBJETIVO: Observar a faixa de distribuição dos alelos do gene FMR1 em uma população de mulheres com infertilidade idiopática, sem sintomas de insuficiência ovariana prematura. MÉTODOS: A presença da pré-mutação em FMR1 foi avaliada por PCR convencional, gel de agarose e acrilamida e análise de fragmentos em eletroforese capilar. Analisou-se DNA de linfócitos obtidos de 283 mulheres em tratamento de infertilidade. RESULTADOS: Foi observado que 169 pacientes apresentam o alelo heterozigoto normal (59,7%), 114 apresentam o alelo homozigoto normal (40,6%) e nenhuma paciente apresentou a pré-mutação. A insuficiência ovariana prematura é observada em 20 a 30% das mulheres portadoras do alelo pré-mutado. Assim, a presença de um alelo pré-mutado pode ser assintomática em grande parte dos casos. O Brasil possui uma população diversificada e, portanto, as frequências alélicas de muitas variantes gênicas são desconhecidas. Estudos brasileiros anteriores mostraram uma baixa frequência do alelo pré-mutado em diferentes coortes de pacientes. Corroborando estes autores, os resultados demonstram que frequência do alelo pré-mutado é baixa na população de mulheres inférteis estudada. CONCLUSÃO: O rastreamento do tamanho dos alelos do gene FMR1 permite ampliar o conhecimento sobre a frequência dos alelos de risco para doenças genética na população brasileira.

Nueva variante del gen STAG3 causante de insuficiencia ovárica prematura / New STAG3 gene variant as a cause of premature ovarian insufficiency

RESUMEN Objetivos: describir un caso de falla ovárica secundaria a una variante patogénica homocigota en el gen STAG3 no reportada previamente. Materiales y métodos: paciente de 16 años con amenorrea primaria y ausencia de características sexuales secundarias, en quien se documentó hipotiroidismo autoinmune, pobre desarrollo genital y cintilla gonadal, por lo cual se realizó secuenciación de exorna clínico. Se identificó una variante homocigota patogénica previamente no reportada en el gen STAG3, el cual ha sido relacionado con insuficiencia ovárica prematura (IOP). Conclusiones: en este caso, la realización de exorna clínico fue determinante para identificar una alteración del gen STAG, probablemente asociada a la IOP y el pronóstico a largo plazo de la paciente. Se establece una nueva variante patogénica c.2773delT; p.Ser925Profs*6 del gen STAG3 asociada a la IOP.

ABSTRACT Objectives: To describe a case of ovarian failure secondary to a homozygous pathogenic variant in the STAG3 gene not previously reported. Material and methods: A 16-year-old patient with primary amenorrhea and absence of secondary sexual characteristics, with documented autoimmune hypothyroidism, poor genital and gonadal streak development which prompted the performance of clinical exorne sequencing. A homozygous pathogenic variant not previously reported in the STAG3 gene, which has been associated with premature ovarian insufficiency (POI), was identified. Conclusions: In this case, clinical exorne sequencing was key for identifying a STAG gene abnormality, probably associated with POI and long term prognosis for the patient. A new pathogenic variant c.2773delT; p.Ser925Profs*6 of the STAG3 gene associated with POI was established.

Insuficiencia ovárica primaria en adolescentes: revisión de la literatura a propósito de un caso clínico / Primary ovarian insufficiency in adolescents: review of the literature regarding a clinical case

El objetivo de este manuscrito es realizar una revisión y actualización de la literatura de la insuficiencia ovárica primaria (IOP) en población adolescente, a partir del diagnóstico, manejo y seguimiento de un caso clínico. La insuficiencia ovárica primaria se define como la menopausia en una mujer antes de los 40 años, acompañada de amenorrea, hipogonadismo hipergonadotrópico e infertilidad. Su prevalencia varía entre 1 a 2%, y en mujeres menores de 20 años su prevalencia es un caso de cada 10,000. Aunque se sabe que muchas afecciones pueden llevar a una IOP, la más común es la causa idiopática. La presentación clínica es diversa, y varios trastornos diferentes pueden también, llevar a esta condición. CASO CLÍNICO: Se presenta el caso de una adolescente de 17 años, previamente sana, con historia de amenorrea secundaria, no embarazada, con examen físico general y ginecológico normal. Se solicita estudio analítico complementario resultando con niveles de hormona folículo estimulante (FHS), estradiol (E2) y hormona antimülleriana (AMH) compatibles con una insuficiencia ovárica como la observada en la posmenopausia. Se inicia terapia hormonal (TH) clásica con estradiol y progesterona, siendo posteriormente reemplazada por anticoncepción hormonal combinada (AHC) oral, coincidente con el inicio de vida sexual, con respuesta favorable y sangrados regulares. La IOP tiene graves consecuencias para la salud incluyendo trastornos psicológicos como angustia, síntomas depresivos o depresión, infertilidad, osteoporosis, trastornos autoinmunes, cardiopatía isquémica, y un mayor riesgo de mortalidad. La enfermedad de Hashimoto es el trastorno autoinmune más frecuente asociado a la IOP. Su tratamiento y diagnóstico deben establecerse de forma precoz para evitar consecuencias a largo plazo. La terapia con estrógenos es la base del tratamiento para eliminar los síntomas de la deficiencia de estrógenos, además de evitar las consecuencias futuras del hipogonadismo no tratado. También el manejo debe incluir los siguientes dominios: fertilidad y anticoncepción, salud ósea, problemas cardiovasculares, función psicosexual, psicológica y neurológica, informando a los familiares y a la paciente sobre la dimensión real de la IOP y la necesidad de tratamiento multidisciplinario en muchos casos. CONCLUSIÓN: El caso presentado, pese a ser infrecuente, permite abordar de manera sistematizada el diagnostico de IOP y evaluar alternativas de manejo plausibles para evitar graves consecuencias en la salud, así como conocer respuesta clínica y de satisfacción de la adolescente.

The objective of this manuscript is to review and update the literature on primary ovarian insufficiency (POI) in an adolescent population, based on the diagnosis, management and follow-up of a clinical case. Primary ovarian insufficiency is defined as menopause in a woman before the age of 40, accompanied by amenorrhea, hypergonadotropic hypogonadism, and infertility. Its prevalence varies between 1 to 2%, and in women under 20 years of age its prevalence is one case in every 10,000. Although it is known that many conditions can lead to POI, the most common is the idiopathic cause. The clinical presentation is diverse, and several different disorders can also lead to this condition. CLINICAL CASE: The case of a 17-year-old adolescent, previously healthy, with a history of secondary amenorrhea, not pregnant, with a normal general physical and gynecological examination is presented. A complementary analytical study is requested, resulting in levels of follicle stimulating hormone (FHS), estradiol (E2) and anti-müllerian hormone (AMH) compatible with ovarian insufficiency such as that observed in postmenopause. Classic hormonal therapy (HT) with estradiol and progesterone was started, later being replaced by combined hormonal contraception (CHC), coinciding with the beginning of sexual life, with a favorable response and regular bleeding. POI has serious health consequences including psychological disorders such as distress, depressive symptoms or depression, infertility, osteoporosis, autoimmune disorders, ischemic heart disease, and an increased risk of mortality. Hashimoto's disease is the most common autoimmune disorder associated with POI. Its treatment and diagnosis must be established early to avoid long-term consequences. Estrogen therapy is the mainstay of treatment to eliminate the symptoms of estrogen deficiency, in addition to avoiding the future consequences of untreated hypogonadism. Management should also include the following domains: fertility and contraception, bone health, cardiovascular problems, psychosexual, psychological and neurological function, informing family members and the patient about the real dimension of POI and the need for multidisciplinary treatment in many cases. CONCLUSION: The case, although infrequent, allows a systematic approach to the diagnosis of POI and evaluate plausible management alternatives to avoid serious health consequences, as well as to know the clinical response and satisfaction of the adolescent.

Terapia hormonal em mulheres com insuficiência ovariana prematura: uma revisão sistemática e meta-análise / Hormone therapy in women with premature ovarian insufficiency: a systematic review and meta-analysis

The aim of this systematic review and meta-analysis was to evaluate the effects of different hormone therapies (HT) on clinical outcomes in women with premature ovarian insufficiency (POI). We included 31 studies totalizing 4142 participants with POI from diverse etiologies, of whom 2619 received HT and 201 received calcium supplementation, vitamin D, placebo, or no treatment. HT was superior to non-treatment, placebo, calcitriol or calcium to preserve bone mineral density (BMD) in women with POI. HT was associated with up to 80% reduction in the prevalence of hot flushes and with stability or improvement in the quality of life scores. HT induced significant increases in uterine volume and endometrial thickness in women with POI. Overall, the studies had good quality, although some lacked blinding of participants and personnel or had incomplete outcome data. We found moderate to high quality evidence that HT with estrogen and progesterone or progestin is beneficial to women with POI, not only to mitigate menopausal symptoms but also to preserve BMD and avoid uterine atrophy. More studies are needed to reassure the long-term safety of this therapy and to assess its possible impact on the risk of hard outcomes such as bone fractures and cardiovascular events.

Esta revisão sistemática e meta-análise buscou avaliar os efeitos de diferentes terapias hormonais (HT) sobre os resultados clínicos em mulheres com insuficiência ovariana prematura (POI). Foram incluídos 31 estudos, totalizando 4.142 participantes com POI de diversas etiologias, dos quais 2.619 receberam HT e 201 receberam suplementação de cálcio, vitamina D, placebo ou nenhum tratamento. HT foi superior ao não tratamento, placebo, calcitriol ou cálcio para preservar a densidade mineral óssea (DMO) em mulheres com POI. A TH foi associada a uma redução de até 80% na prevalência de fogachos e à estabilidade ou melhora nos escores de qualidade de vida. HT induziu aumentos significativos no volume uterino e espessura endometrial em mulheres com POI. No geral, os estudos tiveram boa qualidade, embora alguns não tivessem cegamento dos participantes e do pessoal ou tivessem dados de resultados incompletos. Encontramos evidências de qualidade moderada a alta de que a TH com estrogênio e progesterona ou progesterona é benéfica para mulheres com POI, não apenas para mitigar os sintomas da menopausa, mas também para preservar a DMO e evitar a atrofia uterina. Mais estudos são necessários para assegurar a segurança em longo prazo dessa terapia e para avaliar seu possível impacto sobre o risco de outros desfechos clínicos, como fraturas ósseas e eventos cardiovasculares.

Mulheres submetidas ao transplante de medula óssea: impacto dos quimioterápicos e da doença do enxerto contra o hospedeiro sobre o sistema reprodutor / Women undergoing bone marrow transplantation: impact of chemotherapy and graft-versus-host disease (GVHD) on the feminine reproductive system

O transplante de medula óssea (TMO) é um procedimento indicado para o tratamento de doenças hematológicas, que afetam muitas mulheres jovens. O aperfeiçoamento dos cuidados durante o TMO proporciona altos índices de cura e de sobrevida. No entanto, pode deixar sequelas em vários órgãos e sistemas, entre eles o sistema reprodutor e os órgãos genitais, impactando negativamente a qualidade de vida das receptoras do TMO. O objetivo desta publicação foi realizar uma revisão narrativa sobre o tema e propor um protocolo assistencial que torne acessível os cuidados relacionados à saúde sexual e reprodutiva a esse grupo especial de mulheres, baseado em dados clínicos de um ambulatório de assistência ginecológica às mulheres transplantadas no Hospital Amaral Carvalho, em Jaú, no interior de São Paulo.(AU)

Bone marrow transplantation (BMT) is indicated for the treatment of hematological diseases which affect many young women. The improvement of care during BMT procedures provides higher cure and survival rates. however, it can cause sequelae in various organs and systems, including the reproductive system and genitals, negatively impacting quality of life. The purpose of this publication is to present a narrative review related to this theme and to propose a healthcare protocol that allows sexual and reproductive care in this special group of patients, based on the clinical experience of a gynecological outpatient clinic at the Amaral Carvalho Hospital, in Jaú (SP) which specifically care for these women.(AU)

Amenorrea primaria asociada a paciente con cariotipo 45 XX, ROB (13; 14) (q 10; q 10): presentación de un caso / Primary amenorrhea associated with a patient with karyotype 45 XX, ROB (13; 14) (q 10; q 10): case presentation

La función ovárica depende de la expresión de múltiples genes, por lo que las anomalías del cromosoma X y los autosomas revisten gran importancia en la etiología de la insuficiencia ovárica primaria (IOP). Las translocaciones de autosomas en mujeres con IOP son muy raras y solo se han detectado tres casos: dos translocaciones entre los cromosomas 2 y 15 en dos mujeres con cariotipo 46, XX, t (2, 15) (q32.3, q13.3)2; una translocación entre los cromosomas 13 y 14 en una mujer con cariotipo 45, XX, t (13; 14)3; por lo que nuestro caso sería el cuarto reporte de mujeres con translocaciones de autosomas e IOP.

Ovarian function depends on the expression of multiple genes, so Xchromosome abnormalities and autosomes are of great importance in the etiology of primary ovarian insufficiency (IOP). Autosomal translocations in women with IOP are very rare and only three cases have been detected: two translocations between chromosomes 2 and 15 in two women with karyotype 46, XX, t (2, 15) (q32.3, q13.3)2; a translocation between chromosomes 13 and 14 in a woman with karyotype 45, XX, t (13; 14)3 , so our case would be the fourth report of women with autosomal translocations and IOP.

Effect of ginsenoside Rg_1 in delaying premature ovarian failure induced by D-gal in mice through PI3K/Akt/mTOR autophagy pathway / 中国中药杂志

The aim of this paper was to study the role of phosphoinositide 3-kinase(PI3 K), protein kinase B(Akt) and mamma-lian target of rapamycin(mTOR) in the inhibition of premature ovarian failure induced by D-galactose(D-gal) in mice model by ginsenoside Rg_1(Rg_1). Fifty-four female SPF BALB/c mice were randomly divided into PBS group, D-gal group, and Rg_1 group. In the D-gal group, D-galactose(200 mg·kg~(-1)·d~(-1)) was injected subcutaneously into the neck and back for 42 days. In the PBS group, an equal amount of phosphate buffered saline(PBS) was injected into the neck and back for 42 days. In addition to the therapy of D-gal group, Rg_1 group was given Rg_1(20 mg·kg~(-1)·d~(-1)) through intraperitoneal injection since the 15 th day for 28 days, at the same time, the D-gal group and the PBS group were also given an equal amount of PBS through intraperitoneal injection since the 15 th day for 28 days. After the treatment, the estrous cycle changes of the mice were detected, and the ovarian SA-β-Gal staining was used to detect the changes of ovarian aging. Western blot was used to detect the changes in protein expressions of PI3 K, Akt, mTOR, S6 k, LC3-Ⅱ and P16~(INK4 a). Fluorescence quantitative PCR was used to detect the changes in mRNA expressions of PI3 K, Akt, mTOR, S6 k, LC3-Ⅱ and P16~(INK4 a). According to the findings, compared with the PBS group, the D-gal group began to show estrous cycle disorder in the 3 rd week,the ovarian SA-β-Gal staining positive granulosa cells increased in the D-gal group, the expression of senescence marker P16~(INK4 a) increased, while the expression of autophagy signaling molecule LC3-Ⅱ decreased. After treatment with Rg_1, the positive rate of ovarian SA-β-Gal staining in Rg_1 group decreased, the expression level of autophagy signaling molecule LC3-Ⅱ in Rg_1 group was higher than that in D-gal group, while the expression level of senescence marker P16~(INK4 a) was lower than that in D-gal group. Compared with the PBS group, the protein and mRNA expressions of PI3 K, Akt, mTOR and S6 k in the D-gal group were up-regulated, the protein expressions of Akt, mTOR and S6 k in the Rg_1 group were up-regulated, and the mRNA expressions of PI3 K and mTOR were up-regulated. After treatment with Rg_1, the protein expressions of PI3 K, Akt, mTOR and S6 k in the Rg_1 group were lower than those in the D-gal group, while the mRNA expressions of Akt, mTOR and S6 k in the Rg_1 group were lower than those in the D-gal group. The finding ssuggested that Rg_1 has the effect in delaying ovarian premature failure in D-gal-induced mouse models, and PI3 K/Akt/mTOR autophagy signaling pathways play an important role.

Gestación en paciente con insuficiencia ovárica primaria secundaria a mosaicismo de Síndrome de Turner / Pregnancy in a patient with primary ovarian insufficiency owing to a mosaicism of Turner Syndrome

RESUMEN La Insuficiencia Ovárica Primaria se define por una amenorrea secundaria de al menos cuatro meses de duración, deficiencia de esteroides sexuales (estradiol) y altas concentraciones séricas de hormona folículoestimulante (FSH) con al menos un mes de diferencia entre estas determinaciones, en mujeres menores de 40 años. Es una causa insidiosa de infertilidad pero en algunas ocasiones es transitoria y permite una gestación espontánea. El Síndrome de Turner es un trastorno genético caracterizado por la pérdida o anomalías estructurales de un cromosoma X y que afecta a 1 de cada 2.500 mujeres nacidas vivas. Las manifestaciones clínicas varían entre pacientes, pero generalmente se relaciona con talla baja, coartación aórtica, disgenesia gonadal e insuficiencia ovárica primaria. Las técnicas de reproducción asistida como la criopreservación de ovocitos y de tejido ovárico, la maduración in vitro o la donación de ovocitos ofrecen opciones reproductivas en aquellos casos en los que no se produzca un embarazo espontáneo.

ABSTRACT Primary Ovarian Insufficiency is considered a secondary amenorrhea of at least four months duration, sex steroid deficiency (estradiol) and high serum concentrations of follicle stimulating hormone (FSH) with at least one month difference between these determinations, in women under 40 years. It is an insidious cause of infertility but sometimes it is transient and allows a spontaneous pregnancy. Turner syndrome is a genetic disorder characterized by the loss or structural abnormalities of an X chromosome that affects 1 in 2,500 women born alive. Clinical manifestations vary among patients, but it is usually associated with short stature, aortic coarctation, gonadal dysgenesis, and primary ovarian failure. Assisted reproduction techniques such as cryopreservation of oocytes and ovarian tissue, in vitro maturation or oocyte donation offer reproductive options in those cases in which there is no spontaneous pregnancy.

Fragilidad del X y otras entidades asociadas al gen FMR1: estudio de 28 familias afectadas / Fragile X syndrome and other entities associated with the FMR1 gene: Study of 28 affected families

El síndrome de fragilidad del cromosoma X es la causa de discapacidad intelectual heredable más frecuente. Asociado a trastornos del espectro autista en un tercio de los pacientes, afecta, con mayor prevalencia, a los varones. Se debe a una expansión de trinucleótidos CGG (citosina, guanina, guanina), llamada mutación completa en el locus Xq27.3 del gen FMR1, que conduce a la hipermetilación en el promotor del gen y reduce los niveles de expresión de FMRP, una proteína implicada en la maduración y plasticidad sináptica. Una expansión menor de CGG es la causa de insuficiencia ovárica primaria y del síndrome de temblor/ataxia asociado a X frágil, caracterizado por ataxia cerebelosa progresiva, de inicio tardío, y temblor de intención. En el presente estudio de serie de casos, se analiza la segregación de mutaciones del gen FMR1 en diferentes familias y la variabilidad de expresión clínica que llevó a la consulta genética.

The fragile X syndrome occurs due to an expansion of CGG trinucleotides, called full mutation, which is found at the Xq27.3 locus of the FMR1 gene. It is the most common cause of inherited intellectual disability. Associated with autistic spectrum disorders in one third of the patients, it affects males with higher prevalence. It also leads to hypermethylation of the gene promoter, silencing it and reducing the expression levels of FMRP, a protein involved in synaptic maturation and plasticity. A lower expansion causes primary ovarian failure syndrome as well as tremor and ataxia syndrome characterized by progressive cerebellar ataxia of late onset and intention tremor. In the present case-control study we analyze the segregation of mutations of the FMR1 gene in different families and the variability of expression that led to the genetic consultation.
