RESUMO
OBJECTIVE: This study aimed to determine long-term cardiometabolic effects of hormone therapies initiated within 3 years of onset of menopause after a 14-year follow-up study of participants of the Kronos Early Estrogen Prevention Study (KEEPS). METHODS: KEEPS was a multisite clinical trial that recruited recently menopausal women with good cardiovascular health for randomization to oral conjugated equine estrogens (Premarin, 0.45 mg/d) or transdermal 17ß-estradiol (Climara, 50 µg/d) both with micronized progesterone (Prometrium, 200 mg/d) for 12 d/mo, or placebo pills and patch for 4 years. KEEPS continuation recontacted KEEPS participants 14 years after randomization and 10 years after the completion of the 4-year clinical trial to attend in-person clinic visits. RESULTS: Participants of KEEPS continuation (n = 299 of the 727 KEEPS participants; 41%) had an average age of 67 years (range, 58-73 y). Measurements of systolic and diastolic blood pressures, waist-to-hip ratio, fasting levels of glucose, insulin, lipid profiles, and homeostasis model assessment of insulin resistance were not different among the treatment groups at either KEEPS baseline or at KEEPS continuation visits, or for change between these two visits. The frequency of self-reported diabetes ( P = 0.007) and use of diabetes medications was higher in the placebo than the oral conjugated equine estrogens ( P = 0.045) or transdermal 17ß-estradiol ( P = 0.02) groups, but these differences were not supported by the laboratory measurements of glycemia or insulin resistance. CONCLUSIONS: There was no evidence of cardiovascular and/or metabolic benefits or adverse effects associated with 4 years use of oral or transdermal forms of hormone therapy by recently menopausal women with good cardiovascular health after 10 years.

INTRODUCTION: Estrogens used in women's healthcare have been associated with increased risks of venous thromboembolism (VTE) and breast cancer. Estetrol (E4), an estrogen produced by the human fetal liver, has recently been approved for the first time as a new estrogenic component of a novel combined oral contraceptive (E4/drospirenone [DRSP]) for over a decade. In phase 3 studies, E4/DRSP showed good contraceptive efficacy, a predictable bleeding pattern, and a favorable safety and tolerability profile. AREAS COVERED: This narrative review discusses E4's pharmacological characteristics, mode of action, and the results of preclinical and clinical studies for contraception, as well as for menopause and oncology. EXPERT OPINION: Extensive studies have elucidated the properties of E4 that underlie its favorable safety profile. While classical estrogens (such as estradiol) exert their actions via both activation of nuclear and membrane estrogen receptor α (ERα), E4 presents a specific profile of ERα activation: E4 binds and activates nuclear ERα but does not induce the activation of membrane ERα signaling pathways in specific tissues. E4 has a small effect on normal breast tissue proliferation and minimally affects hepatic parameters. This distinct profile of ERα activation, uncoupling nuclear and membrane activation, is unique.

OBJECTIVE: To describe the prevalence of metabolic disturbances in a large cohort of women with polycystic ovary syndrome (PCOS) in southeastern Brazil and to compare the findings with other cohorts of Brazilian women with PCOS. METHODS: A retrospective study analyzing clinical and laboratory data of 462 women with PCOS treated at an outpatient clinic in a tertiary hospital in southeastern Brazil. Prevalence of insulin resistance, glucose intolerance, type 2 diabetes, dyslipidemia, central obesity, hypertension, and metabolic syndrome was compared to that of other cohorts of age and body mass index-matched Brazilian women with PCOS. RESULTS: Women with PCOS had a median age of 25.0 (21.0-29.0) years and BMI of 28.7 (23.9-34.0) kg/m2 . Prevalence of insulin resistance, glucose intolerance, and type 2 diabetes varied from 39.6% to 55.0%, 7.2% to 28.1%, and 2.0% to 4.1%, respectively. Prevalence of central obesity, dyslipidemia due to decreased high-density lipoprotein cholesterol, hypertriglyceridemia, and metabolic syndrome ranged from 57.8% to 66.4%, 54.1% to 70.4%, 22.9% to 35.1%, and 27.4% to 38.3%, respectively, which did not differ among regions in Brazil. CONCLUSION: Prevalence of metabolic disturbances was high among Brazilian women with PCOS. This study suggests that, from a public health perspective, authorities in Brazil should be aware of and encourage screening for metabolic dysfunction in women with PCOS in all regions of the country.

OBJECTIVE: The aim of this study was to select the minimum effective dose of estetrol (E4) for the treatment of vasomotor symptoms in postmenopausal women. METHODS: This was a multicenter, randomized, double-blind, placebo-controlled study. Postmenopausal women (nâ=â257, of whom 32 were hysterectomized) aged 40 to 65 years, with ≥7 moderate to severe hot flushes (HFs) per day, or 50 or more moderate to severe HFs weekly, received 2.5, 5, 10, or 15âmg E4, or placebo once-daily for a period of 12 weeks. Efficacy was assessed by recording the frequency and severity of HFs. Overall safety was assessed by recording adverse events, measuring endometrial thickness, and monitoring bleeding patterns. Treatment groups were compared using analysis of covariance. RESULTS: The frequency of moderate to severe HFs decreased with all E4 doses. The difference in the percentage change of weekly HF frequency was significant for 15âmg E4 versus placebo at both W4 (-66% vs -49%, Pâ=â0.032) and W12 (-82% vs -65%, Pâ=â0.022). The decrease in severity of HFs was significantly more pronounced for 15âmg E4 than for placebo at both W4 (-0.59 vs -0.33, Pâ=â0.049) and W12 (-1.04 vs -0.66, Pâ=â0.049); the other doses failed to achieve statistical significance. In nonhysterectomized women, endometrial thickness increased during treatment and normalized following progestin treatment at study completion. No endometrial hyperplasia was observed. CONCLUSIONS: Estetrol 15âmg is considered to be the minimum effective daily oral dose for treatment of vasomotor symptoms. Its current seemingly favorable safety profile is further to be confirmed in phase 3 clinical development. : Video Summary:http://links.lww.com/MENO/A591.

Polycystic ovary syndrome (PCOS) affects 6% to 20% of reproductive age women and is the most frequent cause of anovulatory infertility. Its physiopathology may result in part from hypothalamic alterations in the pulsatile secretion of gonadotropin-releasing hormone (GnRH). The neuropeptide kisspeptin participates in the mechanism through stimulation of the hormone's production. The purpose of this study was to review the articles which compared kisspeptin levels in women with PCOS with those of controls. A systematic review of observational studies was conducted in accordance with the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) recommendations. The selected studies encompassed a population of patients with PCOS and controls, whose serum kisspeptin levels were evaluated. The studies were retrieved from the Medline, Cochrane, and Embase databases, and four of them were chosen for the review. In most studies, the serum kisspeptin levels were higher in women with PCOS than in controls notwithstanding the BMI. One of the articles showed that circulating plasma levels of kisspeptin were significantly higher in women with PCOS whose BMI was lower than 25 than in obese and overweight women. Our data suggest a higher concentration of serum kisspeptin in women with PCOS irrespective of their BMI. Further experimental and clinical studies are needed to ascertain the role of kisspeptin in PCOS.

Changes in pituitary-ovarian hormones across the menopausal transition have multiple physiological consequences. However, little is known about how the major types of postmenopausal hormone therapy (HT) affect pituitary-ovarian hormonal relationships. This study evaluated these relationships in recently menopausal women (52.45 ± 2.49 yr of age) in the Kronos Early Estrogen Prevention Study (KEEPS) who were compliant to randomized, double-blinded treatment with oral conjugated equine estrogen (o-CEE; n = 109), transdermal 17ß-estradiol (t-E2; n = 107), or placebo (n = 146). Androstenedione, testosterone, 17ß-estradiol, estrone, follicle-stimulating hormone (FSH), and luteinizing hormone (LH) were measured in serum before (baseline) and 48 mo after randomization to treatment. Descriptive summaries of hormone levels were performed, and multiple regression analyses were used to examine the effects of o-CEE, t-E2, and placebo on these hormone levels at 48 mo, adjusting for baseline levels. A network analysis examined the covariance of changes in hormone levels over the 48 mo within treatment groups. As expected, at 48 mo of treatment, hormone levels differed between women in the two active treatment groups compared with placebo, and network analysis indicated stronger relationships among hormone levels in the t-E2 and o-CEE groups compared with placebo. Associations among testosterone, 17ß-estradiol, FSH, and LH differed between the o-CEE group compared with t-E2 and placebo groups. Thus, two common HT regimens differentially alter pituitary-ovarian hormone levels, altering feedback cycles and interhormonal associations in recently menopausal women. These interactions provide the basis for future studies investigating the impact of hormonal modulation of aging, including cognitive decline in women.

OBJECTIVE: To better characterize the metabolic alterations in various phenotypes of polycystic ovary syndrome (PCOS) in a large homogeneous (Sicilian) Mediterranean population with a low prevalence of obesity. DESIGN: Retrospective study. PATIENTS: A total of 1215 consecutively evaluated women with PCOS divided into four Rotterdam phenotypes (A, B, C and D) and in 108 matched ovulatory, nonhyperandrogenic women. MEASUREMENTS: BMI, fasting glucose, total cholesterol, HDL cholesterol, triglycerides, LDL cholesterol and an oral glucose tolerance test. RESULTS: The overall prevalence of obesity was 31%, metabolic syndrome 6.6%, diabetes 2.1%, altered glucose metabolism 13.1%, and abnormal lipid profile 60%. Phenotype B had the highest prevalence of obesity, metabolic syndrome, altered glucose metabolism and lipid abnormalities compared to other PCOS phenotypes and controls. Phenotype A was more obese and more women had metabolic syndrome compared to phenotypes C and D but phenotype C had a similar prevalence of altered glucose metabolism and lipid abnormalities compared to phenotype A which had a higher BMI. These metabolic abnormalities in A and C were higher compared to phenotype D and controls. Multivariate analysis showed that BMI predicts only abnormalities in fasting glucose and triglycerides, while there was no association with androgens. CONCLUSIONS: In Mediterranean women with PCOS from Sicily with a lower prevalence of obesity, the prevalence of diabetes, altered glucose metabolism and metabolic syndrome were much lower than reported in US studies. Phenotype B was the most metabolically affected phenotype, followed by phenotype A. Phenotype C had an intermediate disorder but with a high prevalence of altered glucose metabolism and lipid alterations. Only the normoandrogenic phenotype D had no metabolic abnormalities.

OBJECTIVE: In the REPLENISH trial, women receiving TX-001HR-an oral, softgel capsule, combining 17ß-estradiol (E2) and progesterone (E2 mg/P4 mg 1/100, 0.5/100), had significantly improved vasomotor symptoms, while having their endometrium protected from hyperplasia. The objective here was to describe P4 levels sufficient to counteract the potential endometrial effects of 1 or 0.5âmg oral E2 with TX-001HR. METHODS: In REPLENISH (phase 3; NCT01942668), serum P4, E2, and estrone (E1) levels were characterized in postmenopausal women treated with TX-001HR (E2 mg/P4 mg: 1/100, 0.5/100, [0.5/50, 0.25/50 and placebo not reported here]) at baseline, week 12, and month 12 for P4, and at baseline, weeks 4 and 12, and months 6, 9, and 12 for E2 and E1. In a phase 1 study, pharmacokinetic parameters were assessed after 7 daily doses of oral E2 mg/P4 mg (1/100 and 0.5/100). RESULTS: In REPLENISH (nâ=â1,835), mean P4 levels were 0.39 to 0.55âng/mL with 100-mg P4 doses; E2 levels were 42.3 to 45.6âpg/mL and 23.0 to 27.4âpg/mL for the 1-mg and 0.5-mg E2 doses, respectively; E1 levels were 214 to 242âpg/mL and 114 to 129âpg/mL for the 1-mg and 0.5-mg E2 doses. In the phase 1 study (nâ=â40; day 7), mean Cavg for P4 was 0.66âng/mL with 100-mg P4 doses; E2 was 38.1âpg/mL and 29.2âpg/mL for 1âmg and 0.5âmg E2, respectively; and E1 was 211 and 106âpg/mL for 1âmg and 0.5âmg E2. All three analytes reached steady state within 7 days; accumulation ratios were 1.36 to 1.94. CONCLUSIONS: P4 levels observed with TX-001HR were similar in the phase 1 and 3 studies, and were associated with no endometrial hyperplasia with either E2 daily dose over 1 year in the REPLENISH phase 3 study, which showed significant improvements in menopausal vasomotor symptoms.

OBJECTIVE: To evaluate efficacy, endometrial safety, and overall safety of a single-capsule 17ß-estradiol-progesterone (TX-001HR) for treating menopausal moderate-to-severe vasomotor symptoms. METHODS: REPLENISH was a phase 3, 12-month, randomized, double-blind, placebo-controlled, multicenter trial. Women (aged 40-65 years) with vasomotor symptoms and a uterus were randomized to daily estradiol (mg)-progesterone (mg) (1/100, 0.5/100, 0.5/50, or 0.25/50), and women in the vasomotor symptoms substudy (women with moderate-to-severe hot flushes [seven or greater per day or 50 or greater per week]) to those estradiol-progesterone doses or placebo. The primary safety endpoint was endometrial hyperplasia incidence at 12 months in all women (the total population), and the primary efficacy endpoints were frequency and severity changes (from daily diaries) in moderate-to-severe vasomotor symptoms with estradiol-progesterone compared with placebo at weeks 4 and 12 in the vasomotor symptoms substudy. A sample size of 250 women in each active treatment arm with two or less endometrial hyperplasia cases would result in 1% or less annual incidence (upper bound 2.5% or less, one-sided 95% CI). RESULTS: One thousand eight hundred forty-five women were enrolled and randomized from August 2013 to October 2015; 1,835 received medication (safety population); 1,255 were eligible for the endometrial safety population; 726 comprised the vasomotor symptoms substudy; their mean age and body mass index were 55 years and 27, respectively; one third were African American. No endometrial hyperplasia was found. Frequency and severity of vasomotor symptoms significantly decreased from baseline with 1 mg estradiol and 100 mg progesterone and 0.5 mg estradiol and 100 mg progesterone compared with placebo at week 4 (frequency: by 40.6 and 35.1 points [1 mg and 100 mg and 0.5 mg and 100 mg, respectively] vs 26.4 points [placebo]; severity: by 0.48 and 0.51 vs 0.34 points) and week 12 (by 55.1 and 53.7 vs 40.2; severity: by 1.12 and 0.90 vs 0.56); 0.5 mg estradiol and 50 mg progesterone improved (P<.05) frequency and severity at week 12, and 0.25 mg estradiol and 50 mg progesterone frequency but not severity at weeks 4 and 12. CONCLUSION: No endometrial hyperplasia was observed while single-capsule estradiol-progesterone provided clinically meaningfully improvements in moderate-to-severe vasomotor symptoms. This estradiol-progesterone formulation may represent a new option, using naturally occurring hormones, for the estimated millions of women using nonregulatory-approved, compounded hormone therapy.

PURPOSE: To examine the effect of low and very low estradiol responses in oocyte donors receiving gonadotropins on clinical outcomes of donor in vitro fertilization (IVF) cycles and to identify possible mechanisms responsible for low estradiol response. METHODS: This is a retrospective cohort study of oocyte donors undergoing antagonist IVF cycles with progression to oocyte retrieval between January 2010 and December 2016 at a single urban academic fertility center. Oocyte yield, fertilization rate, blastocyst rate, percentage of normal embryos on preimplantation genetic screening (PGS), pregnancy outcomes, and follicular fluid steroid profiles were compared between donors with normal estradiol response and those with low estradiol response. RESULTS: Three hundred sixty-six antagonist oocyte donor IVF cycles were identified: 42 cycles had a normal estradiol response (NE2), defined as peak serum estradiol (E2) of over 200 pg/mL per retrieved oocyte; 140 cycles had an intermediate estradiol response (iE2), defined as peak serum E2 between 100 and 200 pg/mL per retrieved oocyte; 110 cycles had a low estradiol response (LE2), defined as peak serum E2 between 50 and 100 pg/mL per retrieved oocyte; and 74 cycles had a very low estradiol response (vLE2), defined as peak serum E2 less than 50 pg/mL per retrieved oocyte. LE2 cycles resulted in a greater number of mature oocytes (22.4 vs. 13.6, p < 0.017), and fertilizations versus NE2 donors (18.5 vs. 10.7, p < 0.017), although the number of transferred or cryopreserved blastocysts were similar between groups (8.6, 6.9 vs. 4.8, p = 0.095, p = 1). The percentage of chromosomally normal embryos after PGS was similar between LE2, vLE2, and NE2 cycles (66.4, 71.8 vs. 63.1%, p = 0.99, p = 1). Pregnancy outcomes were similar between LE2, vLE2, and NE2 cycles. Serum AMH obtained on the day of peak E2 was similar to baseline serum AMH and did not differ between LE2 versus NE2 cycles. Follicular fluid E2 levels paralleled serum E2 levels and were lower in LE2 cycles versus NE2 cycles. CONCLUSION: The prevalence of very low E2 responses in donors appears to be high (20.2%). In contrast to autologous IVF cycles, LE2 does not portend poor outcomes in oocyte donors.

Objective: To update the "Evaluation and Treatment of Hirsutism in Premenopausal Women: An Endocrine Society Clinical Practice Guideline," published by the Endocrine Society in 2008. Participants: The participants include an Endocrine Society-appointed task force of seven medical experts and a methodologist. Evidence: This evidence-based guideline was developed using the Grading of Recommendations, Assessment, Development, and Evaluation system to describe the strength of recommendations and the quality of evidence. The task force commissioned two systematic reviews and used the best available evidence from other published systematic reviews and individual studies. Consensus Process: Group meetings, conference calls, and e-mail communications facilitated consensus development. Endocrine Society committees, members, and cosponsoring organizations reviewed and commented on preliminary drafts of the guidelines. Conclusion: We suggest testing for elevated androgen levels in all women with an abnormal hirsutism score. We suggest against testing for elevated androgen levels in eumenorrheic women with unwanted local hair growth (i.e., in the absence of an abnormal hirsutism score). For most women with patient-important hirsutism despite cosmetic measures (shaving, plucking, waxing), we suggest starting with pharmacological therapy and adding direct hair removal methods (electrolysis, photoepilation) for those who desire additional cosmetic benefit. For women with mild hirsutism and no evidence of an endocrine disorder, we suggest either pharmacological therapy or direct hair removal methods. For pharmacological therapy, we suggest oral combined estrogen-progestin contraceptives for the majority of women, adding an antiandrogen after 6 months if the response is suboptimal. We recommend against antiandrogen monotherapy unless adequate contraception is used. We suggest against using insulin-lowering drugs. For most women who choose hair removal therapy, we suggest laser/photoepilation.

Importance: Sexual dysfunction, an important determinant of women's health and quality of life, is commonly associated with declining estrogen levels around the menopausal transition. Objective: To determine the effects of oral or transdermal estrogen therapy vs placebo on sexual function in postmenopausal women. Design, Setting, and Participants: Ancillary study of the Kronos Early Estrogen Prevention Study (KEEPS), a 4-year prospective, randomized, double-blinded, placebo-controlled trial of menopausal hormone therapy in healthy, recently menopausal women. Of 727 KEEPS enrollees, 670 agreed to participate in this multicenter ancillary study. Women were 42 to 58 years old, within 36 months from last menstrual period. Data were collected from July 2005 through June 2008 and analyzed from July 2010 through June 2017. Interventions: Women were randomized to either 0.45 mg/d oral conjugated equine estrogens (o-CEE), 50 µg/d transdermal 17ß-estradiol (t-E2), or placebo. Participants also received 200 mg oral micronized progesterone (if randomized to o-CEE or t-E2) or placebo (if randomized to placebo estrogens) for 12 days each month. Main Outcomes and Measures: Aspects of sexual function and experience (desire, arousal, lubrication, orgasm, satisfaction, and pain) were assessed using the Female Sexual Function Inventory (FSFI; range, 0-36 points; higher scores indicate better sexual function). Low sexual function (LSF) was defined as an FSFI overall score of less than 26.55. Distress related to low FSFI score (required for the diagnosis of sexual dysfunction) was not evaluated. Results: The 670 participants had a mean (SD) age of 52.7 (2.6) years. The t-E2 treatment was associated with a significant yet moderate improvement in the FSFI overall score across all time points compared with placebo (average efficacy, 2.6; 95% CI, 1.11-4.10; adjusted P = .002). With o-CEE treatment, there was no significant difference in FSFI overall score compared with placebo (mean efficacy, 1.4; 95% CI, -0.1 to 2.8; adjusted P = .13). There was no difference in FSFI overall score between the t-E2 and o-CEE groups on average across 48 months (adjusted P = .22). In the individual domains of sexual function, t-E2 treatment was associated with a significant increase in mean lubrication (0.61; 95% CI, 0.25-0.97; P = .001) and decreased pain (0.67; 95% CI, 0.25-1.09; P = .002) compared with placebo. Overall, the proportion of women with LSF was significantly lower after t-E2 treatment compared with placebo (67%; 95% CI, 55%-77% vs 76%; 95% CI, 67%-83%; P = .04). For o-CEE there was no significant reduction in the odds of LSF. Conclusions and Relevance: Treatment with t-E2 modestly improved sexual function in early postmenopausal women, but whether it relieved symptoms of distress is not known. Trial Registration: clinicaltrials.gov Identifier: NCT00154180.

OBJECTIVE: The objective of the present study was to compare the efficacy of two forms of menopausal hormone therapy in alleviating vasomotor symptoms, insomnia, and irritability in early postmenopausal women during 4 years. METHODS: A total of 727 women, aged 42 to 58, within 3 years of their final menstrual period, were randomized to receive oral conjugated estrogens (o-CEE) 0.45âmg (nâ=â230) or transdermal estradiol (t-E2) 50âµg (nâ=â225; both with micronized progesterone 200âmg for 12 d each mo), or placebos (PBOs; nâ=â275). Menopausal symptoms were recorded at screening and at 6, 12, 24, 36, and 48 months postrandomization. Differences in proportions of women with symptoms at baseline and at each follow-up time point were compared by treatment arm using exact χ tests in an intent-to-treat analysis. Differences in treatment effect by race/ethnicity and body mass index were tested using generalized linear mixed effects modeling. RESULTS: Moderate to severe hot flashes (from 44% at baseline to 28.3% for PBO, 7.4% for t-E2, and 4.2% for o-CEE) and night sweats (from 35% at baseline to 19% for PBO, 5.3% for t-E2, and 4.7% for o-CEE) were reduced significantly by 6 months in women randomized to either active hormone compared with PBO (Pâ<â0.001 for both symptoms), with no significant differences between the active treatment arms. Insomnia and irritability decreased from baseline to 6 months postrandomization in all groups. There was an intermittent reduction in insomnia in both active treatment arms versus PBO, with o-CEE being more effective than PBO at 36 and 48 months (Pâ=â0.002 and 0.05) and t-E2 being more effective than PBO at 48 months (Pâ=â0.004). Neither hormone treatment significantly affected irritability compared with PBO. Symptom relief for active treatment versus PBO was not significantly modified by body mass index or race/ethnicity. CONCLUSIONS: Recently postmenopausal women had similar and substantial reductions in hot flashes and night sweats with lower-than-conventional doses of oral or transdermal estrogen. These reductions were sustained during 4 years. Insomnia was intermittently reduced compared with PBO for both hormone regimens.

OBJECTIVE: To assess the applicability of anti-Müllerian hormone (AMH) testing in the identification of women at risk for polycystic ovary syndrome (PCOS) when AMH is used in ovarian reserve screening in the general population. METHODS: A secondary analysis was undertaken of a large cross-sectional study. Women aged 27-37years, presently delaying childbearing but interested in future fertility, completed an online questionnaire to assess knowledge and attitudes about ovarian reserve testing, and underwent serum AMH testing between October 2014 and April 2015 in New York, NY, USA. For the secondary analysis, women considered to have elevated AMH levels (≥4.7ng/mL) were invited for physical examination and transvaginal ultrasonography. RESULTS: Among 97 women who underwent AMH testing, 32 (33.0%) had elevated AMH levels. Hyperandrogenism was reported by 8 (25.0%) women with elevated AMH and none with AMH concentrations lower than 4.7ng/mL (P<0.001). Irregular menstrual cycles before hormonal contraceptive use were reported by 16 (24.6%) of 65 women with AMH concentrations lower than 4.7ng/mL and 11 (34.4%) with elevated AMH (P=0.34). Of the 20 women with elevated AMH who returned for further evaluation, 16 (80.0%) had polycystic ovaries and 13 (65.0%) were diagnosed with PCOS (Rotterdam criteria). CONCLUSION: When AMH levels are used as a screening test for fertility, elevated concentrations can identify women at risk for PCOS.

Prior to the initiation of menopausal hormone treatment (MHT), genetic variations in the innate immunity pathway were found to be associated with carotid artery intima-medial thickness (CIMT) and coronary arterial calcification (CAC) in women (n = 606) enrolled in the Kronos Early Estrogen Prevention Study (KEEPS). Whether MHT might affect these associations is unknown. The association of treatment outcomes with variation in the same 764 candidate genes was evaluated in the same KEEPS participants 4 yr after randomization to either oral conjugated equine estrogens (0.45 mg/day), transdermal 17ß-estradiol (50 µg/day), each with progesterone (200 mg/day) for 12 days each month, or placebo pills and patch. Twenty SNPs within the innate immunity pathway most related with CIMT after 4 yr were not among those associated with CIMT prior to MHT. In 403 women who completed the study in their assigned treatment group, single nucleotide polymorphisms (SNPs) within the innate immunity pathway were found to alter the treatment effect on 4 yr change in CIMT (i.e., significant interaction between treatment and genetic variation in the innate immunity pathway; P < 0.001). No SNPs by treatment effects were observed with changes of CAC >5 Agatston units after 4 yr. Results of this study suggest that hormonal status may interact with genetic variants to influence cardiovascular phenotypes, specifically, the pharmacogenomic effects within the innate immunity pathway for CIMT.

OBJECTIVE: This study was designed to assess the value of serum anti-Müllerian hormone (AMH) in the diagnosis of polycystic ovary syndrome (PCOS) in various phenotypes and to assess ovarian ultrasound parameters. METHODS: We performed a retrospective matched controlled study of 113 females with various PCOS phenotypes and 47 matched controls. The diagnostic utility of AMH measurement and ovarian ultrasound were compared. Using receiver operating characteristic (ROC) curve analyses, the threshold for AMH (>4.7 ng/mL) and ultrasound parameters (follicle number per ovary [FNPO] >22 and ovarian volume [OV] >8 cc) were established. RESULTS: In the entire cohort, AMH had a low sensitivity of 79%; while FNPO and OV were 93% and 68%, respectively. Specificities ranged from 85 to 96%. In classic anovulatory PCOS, AMH exhibited a sensitivity of 91%, and for FNPO and OV the corresponding sensitivities were 92% and 72%. In the ovulatory phenotype, AMH sensitivity was only 50%, while FNPO and OV were 95% and 50%, respectively. In the nonhyperandrogenic phenotype, the sensitivity of AMH was 53% while those for FNPO and OV were 93% and 67%. CONCLUSION: AMH does not appear to be helpful for all subjects with PCOS but may be of some value in those who are anovulatory. However, FNPO was highly sensitive in all phenotypes, and was the single best criterion assessed for all subjects, suggesting the important role of ultrasound.

BACKGROUND: Menopausal hormone therapy (MHT) reportedly increases the risk of cognitive decline in women over age 65 y. It is unknown whether similar risks exist for recently postmenopausal women, and whether MHT affects mood in younger women. The ancillary Cognitive and Affective Study (KEEPS-Cog) of the Kronos Early Estrogen Prevention Study (KEEPS) examined the effects of up to 4 y of MHT on cognition and mood in recently postmenopausal women. METHODS AND FINDINGS: KEEPS, a randomized, double-blinded, placebo-controlled clinical trial, was conducted at nine US academic centers. Of the 727 women enrolled in KEEPS, 693 (95.3%) participated in the ancillary KEEPS-Cog, with 220 women randomized to receive 4 y of 0.45 mg/d oral conjugated equine estrogens (o-CEE) plus 200 mg/d micronized progesterone (m-P) for the first 12 d of each month, 211 women randomized to receive 50 µg/d transdermal estradiol (t-E2) plus 200 mg/d m-P for the first 12 d of each month, and 262 women randomized to receive placebo pills and patches. Primary outcomes included the Modified Mini-Mental State examination; four cognitive factors: verbal learning/memory, auditory attention/working memory, visual attention/executive function, and speeded language/mental flexibility; and a mood measure, the Profile of Mood States (POMS). MHT effects were analyzed using linear mixed-effects (LME) models, which make full use of all available data from each participant, including those with missing data. Data from those with and without full data were compared to assess for potential biases resulting from missing observations. For statistically significant results, we calculated effect sizes (ESs) to evaluate the magnitude of changes. On average, participants were 52.6 y old, and 1.4 y past their last menstrual period. By month 48, 169 (24.4%) and 158 (22.8%) of the 693 women who consented for ancillary KEEPS-Cog were lost to follow-up for cognitive assessment (3MS and cognitive factors) and mood evaluations (POMS), respectively. However, because LME models make full use all available data, including data from women with missing data, 95.5% of participants were included in the final analysis (n = 662 in cognitive analyses, and n = 661 in mood analyses). To be included in analyses, women must have provided baseline data, and data from at least one post-baseline visit. The mean length of follow-up was 2.85 y (standard deviation [SD] = 0.49) for cognitive outcomes and 2.76 (SD = 0.57) for mood outcomes. No treatment-related benefits were found on cognitive outcomes. For mood, model estimates indicated that women treated with o-CEE showed improvements in depression and anxiety symptoms over the 48 mo of treatment, compared to women on placebo. The model estimate for the depression subscale was -5.36 × 10(-2) (95% CI, -8.27 × 10(-2) to -2.44 × 10(-2); ES = 0.49, p < 0.001) and for the anxiety subscale was -3.01 × 10(-2) (95% CI, -5.09 × 10(-2) to -9.34 × 10(-3); ES = 0.26, p < 0.001). Mood outcomes for women randomized to t-E2 were similar to those for women on placebo. Importantly, the KEEPS-Cog results cannot be extrapolated to treatment longer than 4 y. CONCLUSIONS: The KEEPS-Cog findings suggest that for recently postmenopausal women, MHT did not alter cognition as hypothesized. However, beneficial mood effects with small to medium ESs were noted with 4 y of o-CEE, but not with 4 y of t-E2. The generalizability of these findings is limited to recently postmenopausal women with low cardiovascular risk profiles. TRIAL REGISTRATION: ClinicalTrials.gov NCT00154180 and NCT00623311.

BACKGROUND: Whether menopausal hormone therapy (MHT) protects against cardiovascular disease (CVD) remains unclear. OBJECTIVE: To assess atherosclerosis progression and CVD risk factors after MHT initiated in early menopause. DESIGN: Randomized, controlled trial. (ClinicalTrials.gov: NCT00154180). SETTING: Nine U.S. academic centers. PARTICIPANTS: Healthy menopausal women aged 42 to 58 years between 6 and 36 months from last menses without prior CVD events who had a coronary artery calcium (CAC) score less than 50 Agatston units and had not received estrogen or lipid-lowering therapy for at least 90 days. INTERVENTION: Oral conjugated equine estrogens (o-CEE), 0.45 mg/d, or transdermal 17ß-estradiol (t-E2), 50 mcg/d, each with 200 mg of oral progesterone for 12 days per month, or placebo for 48 months. MEASUREMENTS: Primary end point was annual change in carotid artery intima-media thickness (CIMT). Secondary end points included changes in markers of CVD risk. RESULTS: Of 727 randomly assigned women, 89.3% had at least 1 follow-up CIMT and 79.8% had CIMT at 48 months. Mean CIMT increases of 0.007 mm/y were similar across groups. The percentages of participants in whom CAC score increased did not differ significantly across groups. No changes in blood pressure were observed with o-CEE or t-E2. Low- and high-density lipoprotein cholesterol levels improved and levels of C-reactive protein and sex hormone-binding globulin but not interleukin-6 increased with o-CEE. Insulin resistance decreased with t-E2. Serious adverse events did not differ by treatment. LIMITATION: Power to compare clinical events was insufficient. CONCLUSION: Four years of early MHT did not affect progression of atherosclerosis despite improving some markers of CVD risk. PRIMARY FUNDING SOURCE: Aurora Foundation.

Midlife vascular risk factors influence later cognitive decline and Alzheimer's disease (AD). The decrease in serum estradiol levels during menopause has been associated with cognitive impairment and increased vascular risk, such as high blood pressure (BP), which independently contributes to cognitive dysfunction and AD. We describe the extent to which vascular risk factors relate to cognition in healthy, middle-aged, recently postmenopausal women enrolled in the Kronos Early Estrogen Prevention Cognitive and Affective Study (KEEPS-Cog) at baseline. KEEPS-Cog is a double-blind, randomized, placebo-controlled, parallel group, clinical trial, investigating the efficacy of low-dose, transdermal 17ß-estradiol and oral conjugated equine estrogen on cognition. All results are cross-sectional and represent baseline data only. Analyses confirm that the KEEPS-Cog cohort (n = 571) was middle aged (mean 52.7 years, range 42-59 years), healthy, and free of cognitive dysfunction. Higher systolic BP was weakly related to poorer performance in auditory working memory and attention (p = 0.004; adjusted for multiple comparisons p = 0.10). This relationship was not associated with endogenous hormone levels, and systolic BP was not related to any other cognitive domain. BP levels may be more sensitive than other vascular risk factors in detecting subtle differences in cognitive task performance in healthy, recently menopausal women. Lower BP early in menopause may affect cognitive domains known to be associated with AD.

Several C19 conjugates, derived via 5α-reductase activity, are putative markers of peripheral androgen action and have been shown to correlate well with various clinical manifestations of androgen excess. While no ovarian vein gradient has been found for androsterone sulfate (ADT-S), androsterone glucuronide (ADT-G), 5α-androstane-3α,17ß-diol sulfate (3α-diol-S), and 5α-androstane-3α,17ß-diol glucuronide (3α-diol-G), the contribution of the adrenal gland to these conjugates has been unclear. Ten hirsute women were treated with 2mg/day dexamethasone (dex) for 7 days to determine the effect of adrenal androgen suppression on 5α-reduced androgen conjugate production. In addition, 11 women with mixed ovarian and adrenal androgen excess of non-neoplastic origin underwent ovarian and adrenal vein catheterization studies in order to assess gradients for the various C19 steroids. These women had significantly higher levels of both unconjugated and conjugated androgens, except for ADT-S, compared to 8 matched normal ovulatory women. After dex treatment, total testosterone (TT), unbound T (UT), androstenedione (A) and DHEAS, all decreased by 31-75%. ADT-S, ADT-G, 3α-diol-S and 3α-diol-G decreased by 48%, 71%, 46% and 68%, respectively. The suppression of the unconjugated androgens correlated highly and significantly with ADT-G. In the 11 patients undergoing adrenal venous catheterization, all patients exhibited a substantial adrenal gradient for TT and A. Of significance, in paired samples of peripheral venous and glandular effluents, no adrenal or ovarian gradient was found for any of the conjugated androgens. The data suggest that because dex suppression significantly decreases levels of the conjugated androgens, they are highly substrate dependent. However, since no adrenal or ovarian vein gradient exists, these markers of the manifestations of androgen excess largely reflect peripheral androgen metabolism.
