RESUMEN

Premature ovarian insufficiency (POI) is a primary ovarian defect characterized by premature depletion of ovarian follicles before 40 years of age. The disorder has been attributed to various causes, but the study of altered proteins in serum levels as the cause is rare. Additionally, identifying novel biomarkers can contribute to more accurate diagnosis or prognosis of POI. In the present study, a solid-phase antibody array simultaneously detecting multiple proteins was used to analyze POI serum with menopausal and healthy fertile subjects as control groups. As a result, compared to the menopause and healthy fertile groups, eleven proteins, including Neurturin, Frizzled-5, Serpin D1, MMP-7, ICAM-3, IL-17F, IFN-gamma R1, IL-29, IL-17R, IL-17C and Soggy-1, were uniquely down-regulated, and Afamin was particularly up-regulated in POI serum. More importantly, all of these factors were firstly found to be associated with POI in this study, suggesting that these proteins may participate in the pathogenesis of POI and may be novel serum biomarkers for POI.

RESUMEN

STUDY QUESTION: Are anti-Müllerian hormone (AMH) levels assessed in women aged 32-44 associated with risk of incident early natural menopause? SUMMARY ANSWER: We observed strong, significant associations between lower AMH levels and higher risk of early menopause. WHAT IS KNOWN ALREADY: The ability to predict risk early menopause, defined as menopause before age 45, prior to fertility decline would improve options for family planning and cardiovascular disease prevention. Though AMH is an established marker of menopause timing in older reproductive-aged women, whether AMH is associated with risk of early menopause has not been evaluated. STUDY DESIGN, SIZE, DURATION: We assessed these relations in a nested case-control study within the prospective Nurses' Health Study II cohort. Premenopausal blood samples were collected in 1996-1999. Participants were followed until 2011 for early natural menopause, with follow-up rates >94%. PARTICIPANTS/MATERIALS, SETTING, METHODS: Early menopause cases (n = 327) were women reporting natural menopause between blood collection and age 45. Controls (n = 491) experienced menopause after age 45 and included 327 cases matched to controls on the basis of age at blood draw (±4 months) and other factors. AMH levels up to 12 years before early menopause were assayed in 2016. MAIN RESULTS AND THE ROLE OF CHANCE: In multivariable conditional logistic regression models adjusting for matching factors, body mass index, smoking, parity, oral contraceptive use, and other factors, each 0.10 ng/ml decrease in AMH was associated with a 14% higher risk of early menopause (95% confidence interval (CI) 1.10 to 1.18; P < 0.001). In polynomial regression models including linear and quadratic terms for AMH, odds ratios for early menopause for women with AMH levels of 1.5, 1.0 and 0.5 ng/ml compared to 2.0 ng/ml were 2.6, 7.5 and 23 (all P < 0.001). Significant associations were observed irrespective of smoking status, adiposity, infertility history and menstrual cycle characteristics. Furthermore, models assessing the predictive ability of AMH showed high concordance, and C-statistics were high, ranging from 0.68 (age ≤35) to 0.93 (age 42). LIMITATIONS, REASONS FOR CAUTION: Our population was relatively homogenous with respect to race/ethnicity. Further work in more ethnically diverse populations is needed. WIDE IMPLICATION OF THE FINDINGS: To our knowledge, this is the first prospective study to evaluate whether AMH levels are associated with early menopause. These findings support the utility of AMH as a clinical marker of early menopause in otherwise healthy women. STUDY FUNDING/COMPETING INTEREST(S): This project was supported by UM1CA176726, R01CA67262, and R01HD078517 from the U.S. Department of Health and Human Services, National Institutes of Health. No competing interests declared.

RESUMEN

BACKGROUND: HIV infection has been associated with early menopausal onset, which may have adverse long-term health consequences. Antimüllerian hormone, a biomarker of ovarian reserve and gonadal aging, is reduced in HIV-infected women. OBJECTIVE: We sought to assess the relationship of antimüllerian hormone to age of menopause onset in HIV-infected women. STUDY DESIGN: We used antimüllerian hormone levels measured in plasma in 2461 HIV-infected participants from the Women's Interagency HIV Study to model the age at final menstrual period. Multivariable normal mixture models for censored data were used to identify factors associated with age at final menstrual period. RESULTS: Higher antimüllerian hormone at age 40 years was associated with later age at final menstrual period, even after multivariable adjustment for smoking, CD4 cell count, plasma HIV RNA, hepatitis C infection, and history of clinical AIDS. Each doubling of antimüllerian hormone was associated with a 1.5-year increase in the age at final menstrual period. Median age at final menstrual period ranged from 45 years for those in the 10th percentile of antimüllerian hormone to 52 years for those in the 90th percentile. Other factors independently associated with earlier age at final menstrual period included smoking, hepatitis C infection, higher HIV RNA levels, and history of clinical AIDS. CONCLUSION: Antimüllerian hormone is highly predictive of age at final menstrual period in HIV-infected women. Measuring antimüllerian hormone in HIV-infected women may enable clinicians to predict risk of early menopause, and potentially implement individualized treatment plans to prevent menopause-related comorbidities and to aid in interpretation of symptoms.

RESUMEN

Premature ovarian insufficiency (POI) is defined as a cessation of function of ovaries in women younger than 40 years old. Brain-derived neurotrophic factor (BDNF) is a protein critically involved in neuronal growth and metabolism. BDNF also has been shown to be important regulator of oocyte maturation. Recent data show that BDNF can be potentially involved in POI pathology. The aim of the study was to assess the BDNF plasma concentrations in patients diagnosed with idiopathic POI. 23 women diagnosed with POI (age 31 ± 7 years) and 18 (age 31 ± 3) controls were included to the study, matched according to age and body mass index. The BDNF concentrations were measured using competitive enzyme-linked immunosorbent assay (ELISA). Hormonal and metabolic parameters were measured in all individuals, in controls in late follicular phase. The POI group demonstrated lower mean plasma concentrations of BDNF (429.25 ± 65.52 pg/ml) in comparison to healthy controls (479.75 ± 34.75 pg/ml, p = 0.0345). The BDNF plasma concentration correlated negatively (R = -0.79, p < 0.001) with number of months since last menstrual period. There was a positive correlation between BDNF and progesterone in controls. In conclusion, POI patients show significantly lower BDNF plasma concentration and it correlates with the duration of amenorrhea. This observation brings important potential insights to the pathology of POI.

RESUMEN

Early menopause or premature ovarian insufficiency (POI) is a common cause of infertility in women and affects about one per cent of young women. This disorder has significant psychological sequelae and major health implications. Its relevance has increased in recent years due to the fact that age of motherhood is being delayed in developed countries, with the risk of having either primary ovarian insufficiency or less possibilities of pregnancy. The main characteristics are absence of ovulation, amenorrhoea and high levels of serum gonadotropins (hypergonadotropic hypogonadism). Although the aetiology remains uncertain in most cases, several rare specific causes have been elucidated. Potential causes for POI are iatrogenic (ovarian surgery, radiotherapy or chemotherapy), environmental factors, viral infections, metabolic and autoimmune diseases, and genetic alterations. Because of the association with other autoimmune diseases, close follow up is recommended in patients with POI. The traditional indicators to evaluate ovarian ageing are age, serum hormonal levels, anti-Mullerian hormone, antral follicle count, and ultrasonography of ovaries. Hormone replacement therapy remains the mainstay of treatment, and the best chance of achieving a pregnancy is through oocyte donation. This article aims to present an overview of potential causes, clinical manifestations, and treatment options of POI.

RESUMEN

OBJECTIVE: This study evaluates cardiovascular disease (CVD) risk among women undergoing natural menopause or surgically induced menopause through the measurement of serum growth differentiation factor-15 (GDF-15), B-type natriuretic peptide (BNP), ischemia modified albumin (IMA), total cholesterol, LDL cholesterol (LDL-C), HDL cholesterol (HDL-C), triglyceride, fibrinogen, and C-reactive protein (CRP). MATERIALS AND METHODS: The study included women with surgically induced menopause (n = 50) and women undergoing natural menopause (n = 50). The two study groups were matched according to age, body mass index, menopause duration. GDF-15, BNP, IMA, total cholesterol, LDL-C, HDL-C, triglyceride, fibrinogen, and CRP were measured. RESULTS: There was no significant difference in GDF-15, BNP, IMA, total cholesterol, LDL-C, HDL-C, triglyceride, fibrinogen, and CRP results between the two groups. CONCLUSION: We conclude that there is no increase in CVD risk among women aged 40-50 with surgically induced menopause relative to matched control subjects undergoing normal age-related menopause.

RESUMEN

Introduction: Early menopause may be associated with serious health risks resulting from, for example, decreased oestrogen levels. This may occur despite hormone replacement therapy. Aim: The aim of this study was the determination of the effect of selected reproductive factors and smoking on age at the onset of menopause in women from Szczecin and surrounding areas. Material and Methods: 305 women after natural menopause were asked to complete a questionnaire, and blood samples were collected from them to test for the levels of follicle stimulating hormone (FSH) and oestradiol (E2). Results: Smoking women experienced menopause on average more than a year earlier than non-smokers, but this difference was not statistically significant. There was no statistically significant effect of age at menarche or first birth on age at the last menstrual period. Conclusions: Age at menarche and first birth were not related to age at menopause. In smoking women, menopause occurred earlier but the difference was not statistically significant.

RESUMEN

Premature ovarian insufficiency (POI) is an ovarian dysfunction characterized by increased FSH levels and amenorrhea before 40 years old. In recent years, the search for genetic causes of POI intensified and studies have been published relating the presence of mutations and polymorphisms in genes associated with development, recruitment and oocyte atresia. The aim of this study was to evaluate the presence of FSHR polymorphisms in our population and contribute with the elucidation of POI etiology. To achieve it, we have studied 100 patients with POI (G1), 60 patients with border line levels of FSH (G2) and 123 controls with regular menopause onset. Cytogenetic analysis of patients' samples and genotyping of Asn680Ser and Ala307Thr polymorphisms were performed in cases and controls. Cytogenetic analysis showed that 92% of G1 patients had normal karyotype, 4% presented polymorphic variants, 3% presented mosaic karyotype involving X chromosome. In G2, 91.6% had normal karyotype results, 3.2% displayed polymorphic variants, and 3.3% presented a mosaic karyotype involving X chromosome. Statistical comparison showed that the polymorphic allele of Ala307Thr polymorphism is more frequent in patients than in controls (G1: p < 0.001 and G2: p = 0.0259). This association has not been previously reported. We concluded that Ala307Thr polymorphism in FSHR can be potentially associated to POI development and can be considered as a screening marker in patients with ovarian failure signals.

RESUMEN

The prediction of menopause and premature ovarian insufficiency (POI) involves understanding the factors that contribute to the timing of these events. Menopause is a natural biological process marked by the cessation of menstrual periods, typically occurring around the age of 51. On the other hand, POI refers to the loss of ovarian function before the age of 40. Several factors have been used to predict menopause and POI such as age, antimüllerian hormone, inhibins and follicle-stimulating hormone serum levels, antral follicle counts, menstrual cycle length, and, recently, some genetic markers. It seems that age has the best predictive power and all the other ones are only adding in a very limited way to the prediction of menopause. Low levels of antimüllerian hormone in young women might indicate a greater risk for POI and could facilitate early diagnosis. It is, however, important to note that predicting the exact timing of menopause and POI is challenging, and individual variations are significant. Although these factors can provide some insights, they are not foolproof predictors. Advances in medical research and technology may lead to more accurate methods for predicting menopause and POI in the future.

RESUMEN

Anticancer treatment can disturb gonadal function and deplete the primordial follicle pool, leading to premature menopause. We made a prospective analysis of serum hormone levels in young female cancer survivors who had been treated during childhood and adolescence. Serum anti-Müllerian hormone (AMH) as a marker of ovarian reserve, FSH, LH, and estradiol were measured in 33 women treated previously (6-11 years earlier) for Hodgkin Lymphoma, solid tumours, and after bone marrow transplantation, and in 34 healthy controls. The group of survivors was divided according to the risk of gonadotoxicity into the low risk and median risk group (LR+MR), and into the high risk (HR) group. The measurements were repeated after 5 years. In the HR group, AMH levels were significantly lower than in controls (p=0.001) and in the LR+MR group (p=0.006) at the time of the first examination fell progressively after 5 years (p=0.03), whereas elevated FSH values (p=0.053) increased (p=0.001). Unchanged LH values in the first measurement rose in the second one (p=0.001). In the LR+MR group, the levels of AMH and FSH were normal (compared to the control) at baseline, but after 5 years serum AMH decreased (p=0.027) and FSH increased (p=0.008). Our findings indicate that anticancer treatment during childhood and adolescence is associated with a serious, progressive risk of ovarian failure. It is necessary to inform female cancer survivors, especially the high risk patients, about the risk of premature menopause.

RESUMEN

OBJECTIVE: Premature menopause in young women is associated with an increased incidence of cardiovascular disease. The present study was designed to determine vitamin D (vit D) and the coagulation parameters such as activated partial thromboplastin time (APTT), PT, D-dimer, white blood cell (WBC), and mean platelet volume (MPV) levels, in primary ovarian insufficiency (POI) patients and control women with a normal menstrual cycle. MATERIALS AND METHODS: A total of 43 patients with non-diabetic POI were studied in order to evaluate and compare with the control group comprising 33 women with a normal menstrual cycle. RESULTS: There was no significant difference between the groups for age and body mass index (BMI). D-dimer, WBC, MPV, PT, total cholesterol, and LDL cholesterol were higher in women with POI. APTT levels were also increased but missed the significance in POI group. Women with POI had significantly lower serum vit D levels compared with healthy control group. FSH level was positively correlated with D-dimer, WBC, MPV, and negatively correlated to vit D and serum D vit level was inversely correlated with MPV, APTT, D-dimer, FSH levels in individual women. CONCLUSIONS: The obtained results seem to indicate that POI patients had low-grade systemic coagulation and fibrinolytic activation as evidenced by elevated D-dimer, WBC, MPV, PT values potentially be used as indicators of risk factor for thrombosis and atherosclerosis in POI women. All of our patients with POI were deficient in vit D. These results also suggest that vit D deficiency plays important roles of POI women and associated with coagulation, independently from age and BMI.

RESUMEN

OBJECTIVE: To evaluate the influence of the abrupt withdrawal of ovarian function on glucose tolerance by studying premenopausal women before and after oophorectomy. METHODS: Thirty premenopausal women who needed hysterectomy for benign reasons volunteered for the study in our hospital in Istanbul, Turkey. An oral glucose tolerance test (OGTT) was performed before surgery and 3, 6 and 12 months after surgery. Fasting glucose, fasting insulin levels and insulin/glucose indexes, HOMA indexes, insulin and glucose levels were measured during OGTT. RESULTS: The mean fasting and 2-h glucose levels of the women did not change significantly during the 12 months of follow-up. However, the glucose levels during the glucose tolerance tests changed significantly after surgery (p<0.05). Insulin responses to the glucose tolerance test also increased significantly (p<0.005). Insulin/glucose indexes were significantly higher after surgery (p<0.005). Type 2 diabetes mellitus was detected in five women and impaired glucose tolerance was detected in 12 of the 30 patients after surgery in the 12-month period. CONCLUSION: The impairment of carbohydrate metabolism due to an abrupt decrease in natural estrogen levels should be considered before removing the ovaries during hysterectomy in premenopausal patients.

RESUMEN

AIMS: The aims of this study were (1) to investigate the determining risk factors related to early menopause and (2) to compare the relationships between demographic characteristics and hormonal status and leptin levels in subjects with early (no surgical) and natural menopause. STUDY DESIGN: The prospective study was conducted on 500 women with early and 2700 women with natural menopause. Detailed information was collected about their employment status, past and present smoking habits, coffee and alcohol use, educational level and other factors relevant to health. Thirty participants with early menopause and 30 participants with natural menopause were evaluated for hormone and leptin levels. RESULTS: Employment status (OR: 1.94), current smoking (OR: 1.80) and divorced marital status (OR: 1.79) were found to be significant risk factors for early menopause. Mean levels of leptin in natural and early menopause were measured 11.40 ± 4.1 ng/ml and 8.01 ± 3.9 ng/ml, respectively (p = 0001). Leptin levels in the early (r = 0.765, p = 0.001) and natural (r = 0.750, p = 0.001) menopause subjects correlated positively with oestradiol (E2) levels. CONCLUSION: This study shows that early onset of menopause is correlated with smoking, employment status, divorced marital status and lower leptin levels.

RESUMEN

OBJECTIVE: The aim of this study was to investigate and to compare the effects on serum homocysteine levels of early initiated oral and transdermal oestrogen replacement therapies (ERTs) given to women without a uterus who had undergone surgically induced menopause. Homocysteine levels are considered one of the predictors of cardiovascular disease risk. METHODS: This study included 45 women with surgical menopause. Of 45 women, 15 received oral ERT, (oestradiol hemihydrate 2 mg/day, Estrofem®), 15 received transdermal ERT (oestradiol hemihydrate 0.1% gel 1.5 mg/day, Estreva®) and 15 received no hormone therapy. Blood samples were collected from all women to measure homocysteine levels at the mean time of 15 weeks after surgical menopause. Obtained results of the groups were compared. RESULTS: There were no significant differences in age, height, weight, body mass index (BMI), waist circumference and time elapsing since menopause between the three groups. The duration of ERT was not significantly different between the therapy groups. There was no significant difference in homocysteine levels between the groups (p>0.05). No significant correlation was found between weight, BMI and homocysteine levels (p>0.05). CONCLUSION: Considering that homocysteine is a predictor of risk for cardiovascular disease, the results of this study showed that early initiation of ERT in healthy surgically induced menopausal women neither protects nor deteriorates cardiovascular disease.

RESUMEN

The production of anti-müllerian hormone for the ovarian follicles begins near the puberty and the circulating levels begin to descend progressively in the stage of the pre-menopause coinciding with the depletion follicular and in consequence the menstrual cycles become irregular, frequently anovulatories. Therefore, concentration of anti-müllerian hormone shows a close correlation with follicular reserve and reproductive capacity, more than FSH and estradiol measurements. We described two patients that developed premature ovarian failure without previous diagnosis and therefore just were treated pharmacologically with estrogen-progestagen to induce menstrual bleeding. In blood of both patients was found low levels (< or = 4 ng/mL) of anti-müllerian hormone, and by means of sonography the absence of follicles was demonstrated in the ovaries. Has intended that premature ovarian failure could be of a chromosomal dysfunction, similar to other gonadal dysgenesias, another explanation of the mechanism is that it could be for development of some autoimmunity dysfunction. Therefore, the combined hormonal substitution of estrogen with progestagen should stay during several years to avoid the complications for the lack of estrogens; in some cases, could be informed on offering the pregnancy possibility by means of the attended fertilization using ovules donor.

Anti-Müllerian Hormone (AMH) is produced by small antral follicles and has evolved over the past three decades as an assumed potential marker of the number of follicles in the human ovaries, also known as ovarian reserve. This quantitative measure, given the gradual decline over time and its non-replenishable feature, could be the dreamed marker for predicting the final exhaustion of ovarian storage: the post-menopause. This introductory chapter summarizes current knowledge with regard to the contribution of serum AMH measurements to predict age of normal menopause and critically discuss its potential in this regard. Furthermore, its predictive role in the context of menopause in association with several frequently occurring fertility disorders such as premature menopause, polycystic ovarian syndrome and endometriosis are discussed. Overall, while ovarian reserve markers including AMH are unmistakably related to age at menopause, they are insufficiently precise to inform on an individual's journey of ovarian aging.

RESUMEN

CONTEXT: Primary ovarian insufficiency (POI) is defined by menopause before 40 years of age. POI prevalence is higher among women with autoimmune Addison's disease (AAD) than in the general population, but their clinical characteristics are insufficiently studied. OBJECTIVE: To assess the prevalence of POI in a large cohort of women with AAD and describe clinical, immunological, and genetic characteristics. METHODS: An observational population-based cohort study of the Norwegian National Addison Registry. The Norwegian Prescription Database was used to assess prescription of menopausal hormone replacement therapy (HRT). A total of 461 women with AAD were studied. The primary outcome measure was prevalence of POI. Secondary outcomes were clinical characteristics, autoantibodies, and genome-wide single nucleotide polymorphism variation. RESULTS: The prevalence of POI was 10.2% (47/461) and one-third developed POI before 30 years of age. POI preceded or coincided with AAD diagnosis in more than half of the women. The prevalence of concomitant autoimmune diseases was 72%, and AAD women with POI had more autoantibodies than AAD women without (≥2 autoantibodies in 78% vs 25%). Autoantibodies against side-chain cleavage enzyme (SCC) had the highest accuracy with a negative predictive value for POI of 96%. HRT use was high compared to the age adjusted normal population (11.3 % vs 0.7%). CONCLUSION: One in 10 women with AAD have POI. Autoantibodies against SCC are the most specific marker for autoimmune POI. We recommend testing women with AAD <40 years with menstrual disturbances or fertility concerns for autoantibodies against SCC.

RESUMEN

BACKGROUND: Women with systemic lupus erythematosus (SLE) are at risk of premature ovarian failure when treated with cyclophosphamide. This risk is increased when autoimmune thyroid disease is present. We undertook this study to determine whether the presence of ovarian autoimmunity also increased the risk of early ovarian failure among women receiving cyclophosphamide. METHODS: We examined the records of women enrolled in the Lupus Family Registry and Repository, a cross-sectional study of ~3300 SLE subjects, for treatment with cyclophosphamide as well as menopausal status. We defined premature menopause as permanent, spontaneous cessation of menstruation before age 45. We measured anti-ovarian antibodies by enzyme-linked immunosorbent assay using stored sera. RESULTS: There were 258 women treated with cyclophosphamide in whom presence of absence or premature menopause could by defined. A total of 169 (65.6%) had premature ovarian failure, while 89 (34.6%) did not. While anti-ovarian antibodies were present in a small percentage of patients, there was no association of premature menopause to either level of these antibodies (16.2 ± 20.3 units vs 17.4 ± 21.7 units, P = NS by Fisher's exact test), or positivity on this testing (11 of 169 [6.5%] positive vs 8 of 89 [8.9%], χ2  = 0.53, P = .46, 95% CI 0.95-1.1). Neither renal disease nor hypothyroidism increased the risk of premature ovarian failure in these women receiving cyclophosphamide. CONCLUSION: Anti-ovarian antibodies among women with SLE are not associated with premature ovarian failure after treatment with cyclophosphamide.

RESUMEN

In this study, comparing four different parameters in women with surgical menopause because of ovariectomy in reproductive age and in women with natural menopause, the effect of withdrawal of ovarian hormones on both groups was investigated. The patient groups in this study were constituted of 100 women in reproductive age who had undergone total abdominal hysterectomy + bilateral salpingo-oophorectomy and 50 women with natural menopause referred to out-patient's clinic within the same period. The findings for four different parameters were recorded one day before the surgery and at 3rd month post-operatively in surgical menopause group and at the day of referral to outpatient clinic in natural menopause group. The parameters planned to be recorded were blood lipid profile, thrombotic system, arterial elasticity and psychosexual variations. Post-operative high-density lipoprotein level in surgical menopause group was found lower than that of natural menopause group (47.08 vs 52.44 mg/dL, P < 0.05). Post-operative very low density lipoprotein level in surgical menopause group was increased more than that in natural menopause group (27.74 vs 23.58 mg/dL, P < 0.05). An increase was observed in post-operative carotid artery Pulsality Index and Resistive Index levels of surgical menopause group compared with natural menopause group (1.44 vs 1.33, P < 0.001 and 0.73 vs 0.68, P < 0.001 respectively). In surgical menopause group, the differences between pre- and post-operative values of bleeding time (1.15 vs 1.24, P < 0.0001), clotting time (5.9 vs 6.08, P < 0.0001) and fibrinogen level (422 vs 395, P < 0.0001) were found statistically significant. While bleeding time and clotting time were increased post-operatively, fibrinogen level was decreased. A significant increase was observed in post-operative mean Kupperman Index levels of surgical menopause group compared with that of natural menopause group (23.89 vs 9.94, P < 0.001). It was concluded that the ovaries should be considered as important organs impacting women's quality of life with their hormones produced also in the period of menopause; that disadvantages of oophorectomy during hysterectomy should be considered and that an attempt to conserve ovaries during surgery except pre-cancerous events would benefit women.
