Menopause

The REPLENISH trial evaluated the oral 17β-estradiol/progesterone (E2/P4) softgel capsule (TX-001HR; 1 mg E2/100 mg P4) approved by the US Food and Drug Administration in October 2018 as Bijuva (TherapeuticsMD) for the treatment of moderate to severe vasomotor symptoms (VMS) due to menopause. In separate subanalyses presented at the annual Scientific Meeting of the North American Menopause Society in Chicago, Illinois (September 25-28, 2019), researchers examined E2/P4’s ability to address VMS according to age and body mass index (BMI), ability to address sleep, and appropriate dosing in smokers versus nonsmokers.

REPLENISH

The REPLENISH trial was a phase 3, randomized, double-blind, placebo-controlled, multicenter trial evaluating the safety and efficacy of E2/P4 for the treatment of VMS in 1,835 postmenopausal women aged 40 to 65 years with a uterus. Women with moderate to severe VMS (≥7/day or ≥50/week) were randomly assigned to E2/P4 (mg/mg) 1/100, 0.5/100, 0.5/50, 0.25/50, or placebo.¹

E2/P4 and VMS according to age and BMI

Percent changes in the weekly frequency and severity of moderate to severe VMS from baseline to weeks 4 and 12 versus placebo were analyzed by age (<55 and ≥55 years) and BMI in the study participants.¹ The BMI subgroups had similar baseline VMS, but women in the younger age group had higher baseline frequency of moderate to severe VMS than women in the older age group.

Age. The percent changes in VMS frequency from baseline for women treated with E2/P4 were similar at weeks 4 and 12 between age groups. While subgroup analyses were not powered for statistical significance, significant differences were observed between E2/P4 dosages and placebo at week 12. For VMS severity, the percent changes from baseline for women treated with E2/P4 ranged from 16% to 22% at week 4 and 24% to 51% for either age group at week 12.

BMI. When analyzed by BMI, larger percent reductions from baseline in VMS frequency and severity were observed with E2/P4 dosaging versus placebo, with some groups meeting statistical significance at both weeks 4 and 12.

The authors concluded that their subgroup analyses show a consistency of efficacy for VMS frequency and severity among the different age group and BMI populations of women treated with E2/P4.

E2/P4 and sleep outcomes

Participants in the REPLENISH trial took 2 surveys related to sleep—the Medical Outcomes Study (MOS)-Sleep, a 12-item questionnaire measuring 6 sleep dimensions, and the Menopause-specific Quality of Life (MENQOL), which included a “difficulty sleeping” item.² Except for women treated with E2/P4 0.25/50 at week 12, women receiving E2/P4 reported significantly better change in the MOS-Sleep total, as well as better ratings on sleep problems and disturbance subscales, than women treated with placebo at week 12 and months 6 and 12. The incidence of somnolence was low with E2/P4 treatment. In addition, sleep mediation models showed that E2/P4 improved MOS-sleep disturbances indirectly through improvements in VMS. The study authors concluded that women taking E2/P4 for moderate to severe VMS may experience improved sleep.

Smoking and E2/P4 dosage

Among postmenopausal women, smoking has been shown to reduce the efficacy of hormone therapy.³ Researchers found that nonsmokers (never or past smokers) may benefit more from a lower E2/P4 dosage than current smokers (<15 cigarettes per day).⁴ (Women smoking ≥15 cigarettes per day or any e-cigarettes were excluded from REPLENISH). Compared with nonsmokers taking placebo, nonsmokers taking any dosage of E2/P4 had a significant and clinically meaningful reduction in VMS frequency and severity beginning at week 4 and maintained through week 12 (except for the E2/P4 dosage of 0.5/50 at week 4 for severity). By contrast, current smokers in any E2/P4 group had no significant VMS improvements from baseline to weeks 4 and 12 compared with placebo, and proportions of smokers who did measure some response to treatment (at both ≥50% and ≥75% levels) were not different from placebo at weeks 4 and 12. In addition, current smokers had significantly lower median levels of systemic estradiol and estrone concentrations with all E2/P4 treatment groups than did nonsmokers, despite both groups having similar estradiol and estrone concentrations at baseline.

The REPLENISH trial evaluated the oral 17β-estradiol/progesterone (E2/P4) softgel capsule (TX-001HR; 1 mg E2/100 mg P4) approved by the US Food and Drug Administration in October 2018 as Bijuva (TherapeuticsMD) for the treatment of moderate to severe vasomotor symptoms (VMS) due to menopause.

Researchers from Kaiser Permanente Northwest and Oregon Health & Science University, both in Portland, performed a secondary analysis of a survey of postmenopausal women conducted to assess the impact of a health system intervention on genitourinary syndrome of menopause (GSM). They presented their results at the recent annual Scientific Meeting of the North American Menopause Society in Chicago, Illinois (September 25-28, 2019). The intervention included clinician education and computer support tools and was assessed in a clinic-based, cluster-randomized trial in which primary care and gynecology clinics either received the intervention or did not. Women received follow-up 2 weeks after a well-woman visit with a survey that elicited vulvovaginal, sexual, and urinary symptoms with bother.

About 45% of those responding to the survey (N = 1,533) reported 1 or more vulvovaginal atrophy (VVA) symptoms—on average described as somewhat or moderately bothersome—but less than half of those women (39%) discussed their symptom(s) at their well-woman visit. Typically it was the woman, rather than the clinician, who initiated the discussion of the VVA symptom(s) (59% vs 22%, respectively). About 16% of women reported that both parties brought up the symptom(s). Most women (83%) were satisfied with the VVA symptom discussion. Of the women not having such a discussion, 18% wished that one had occurred. A VVA symptom discussion was positively associated with clinicians providing written materials, suggesting lubricants or vaginal estrogen, and providing a referral. Therefore, there is a greater role for clinician-initiated screening for GSM, the study authors concluded.

In a recent systematic review, Fink and colleagues attempted to summarize the published evidence of the efficacy and safety of long-term (> 3 years) therapy for osteoporosis.¹ Unfortunately, they arrived at very limited and tentative conclusions because, as they point out, of the paucity of such evidence.

Why long-term studies stop short

Only 3 of the several tens of placebo-controlled fracture end-point studies (about 58 trials and observational studies) that Fink and colleagues reviewed evaluated treatment for more than 3 years. The nonavailability of longer-term studies is the direct consequence of a requirement by regulatory agencies for a 3-year fracture end-point study in order to register a new drug for osteoporosis. Hence, longer, placebo-controlled studies do not benefit the industry sponsor, and enrolling patients with osteoporosis or who are at high risk for fracture in any, much less long, placebo-controlled trials is now considered to be unethical.

What the authors did observe

From this limited set of information with which to evaluate, Fink and colleagues observed that long-term therapy with raloxifene reduces the risk of vertebral fractures but is associated with thromboembolic complications. In addition, treatment for more than 3 years with bisphosphonates reduces the risk of vertebral and nonvertebral fractures but may increase risk of rare adverse events (including femoral shaft fractures with atypical radiographic features).

The bisphosphonate holiday. The authors refer to the even more limited evidence about the effects of discontinuing bisphosphonate therapy. Unlike the rapid loss of bone mass density (BMD) and fracture protection upon stopping estrogen or denosumab, the offset of these treatment benefits is slower when bisphosphonates are discontinued. This, coupled with concern about increasing risk with long-term bisphosphonate therapy, led to the confusing concept of a “bisphosphonate holiday.” While recommendations to consider temporary discontinuation of bisphosphonates in patients at low risk for fracture have been made by expert panels,² very little information exists about the benefits/risks of this strategy, how long the treatment interruption should be, or how to decide when and with what to restart therapy. Unfortunately, overall, Fink and colleagues’ observations provide little practical guidance for clinicians.

What we can learn from longer term and recent studies of ideal treatment

Since we have no “cure” for osteoporosis, and since the benefits of therapy, including protection from fractures, abate upon stopping treatment (as they do when we stop treating hypertension or diabetes), very long term if not lifelong management is required for patients with osteoporosis. Persistent or even greater reduction of fracture risk with treatment up to 10 years, compared with the rate of fracture in the placebo or treated group during the first 3 years of the study, has been observed with zoledronate and denosumab.^3-5 Denosumab was not included in the systematic review by Fink and colleagues since the pivotal fracture trial with that agent was placebo-controlled for only 3 years.⁶

Sequential drug treatment may be best. Fink and colleagues also did not consider new evidence, which suggests that the use of osteoporosis drugs in sequence—rather than a single agent for a long time—may be the most effective management strategy.^7,8

More consideration should be given to the use of estrogen and raloxifene in younger postmenopausal women at risk for vertebral but not hip fracture.

Only treat high-risk patients. Using osteoporosis therapies to only treat patients at high risk for fracture will optimize the benefit:risk ratio and cost-effectiveness of therapy.

Bisphosphonate holidays may not be as important as once thought. BMD and fracture risk reduction does not improve after 5 years of bisphosphonate therapy, and longer treatment may increase the risk of atypical fractures, while switching to another agent can increase BMD and perhaps mitigate the safety concern, suggesting that there is little justification for continuous use of bisphosphonates for more than 5 years, thereby minimizing the importance of a bisphosphonate holiday.

Hip BMD may serve as indicator for treatment decisions. Recent evidence indicating that the change in hip BMD with treatment or the level of hip BMD achieved on treatment correlates with fracture risk reduction may provide a useful clinical target to guide treatment decisions.^9,10

Because we have a lack of pristine evidence does not mean that we shouldn’t treat osteoporosis; we have to do the best we can with the limited evidence we have. Therapy must be individualized, for we are not just treating osteoporosis, we are treating patients with osteoporosis.

A new international position statement on testosterone therapy for women concludes that a trial of testosterone is appropriate for postmenopausal women with hypoactive sexual desire dysfunction (HSDD) and that its use for any other condition, symptom, or reason is not supported by available evidence.

The seven-page position statement, developed by an international task force of experts from the Endocrine Society, the American College of Gynecologists and Obstetricians, and multiple other medical societies, also emphasized that blood concentrations of testosterone should approximate premenopausal physiological conditions.

“When testosterone therapy is given, the resultant blood levels should not be above those seen in healthy young women,” said lead author Susan Ruth Davis, PhD, MBBS, of Monash University in Melbourne, Australia, in a press release issued by the Endocrine Society. Dr. Davis is president of the International Menopause Society, which coordinated the panel.

The statement was published in the Journal of Clinical Endocrinology & Metabolism and three other medical journals.

Margaret E. Wierman, MD, who represented the Endocrine Society on the task force, said in an interview that there has been “growing concern about testosterone being prescribed for a variety of signs and symptoms without data to support” such use. At the same time, there is significant concern about the ongoing lack of approved formulations licensed specifically for women, she said.

In part, the statement is about a renewed “call to industry to make some [female-specific] formulations so that we can examine other potential roles of testosterone in women,” said Dr. Wierman, professor of medicine and physiology at the University of Colorado at Denver, Aurora, and chief of endocrinology at the Rocky Mountain Regional Veterans Affairs Medical Center in Aurora.

“Testosterone may be useful [for indications other than HSDD], but we don’t know. There may be no [breast or cardiovascular disease risk], but we don’t know,” she said. “And without a formulation to study potential benefits and risks, it’s good to be cautious. It’s good to really outline where we have data and where we don’t.”

The Endocrine Society’s 2014 clinical practice guideline on androgen therapy in women, for which Dr. Wierman was the lead author, also recommended against the off-label use of testosterone for sexual dysfunction other than HSDD or for any other reason, such as cognitive, cardiovascular, metabolic, or bone health. As with the new statement, the society’s position statement was guided by an international, multisociety task force, albeit a smaller one.

For the new global position statement, the task force’s review of evidence includes a recently published systematic review and meta-analysis of randomized controlled trial data – of at least 12 weeks’ duration – on the use of testosterone for sexual function, cardiometabolic variables, cognitive measures, and musculoskeletal health. Some of the data from the randomized controlled trials were unpublished.

The meta-analysis, led by Dr. Davis and published in July in the Lancet Diabetes & Endocrinology, found that, compared with placebo or a comparator (such as estrogen, with or without progesterone), testosterone in either oral or transdermal form significantly improved sexual function in postmenopausal women. However, data about the effects of testosterone for other indications, its long-term safety, and its use in premenopausal women, were insufficient for drawing any conclusions (Lancet Diabetes Endocrinol. 2019 Jul 25. doi: 10.1016/S2213-8587[19]30189-5).

In addition, testosterone administered orally – but not nonorally (patch or cream) – was associated with adverse lipid profiles, Dr. Davis and her colleagues reported.

Another systematic review and meta-analysis, published in Fertility and Sterility in 2017 and included in the task force’s evidence review, focused specifically on transdermal testosterone for menopausal women with HSDD, with or without estrogen and progestin therapy. It also showed short-term efficacy in terms of improvement in sexual function, as well as short-term safety (Fertil Steril. 2017;107(2):475-82).

The new position statement warns about the lack of long-term safety data, stating that “safety data for testosterone in physiologic doses are not available beyond 24 months of treatment.”

In the short term, testosterone therapy for postmenopausal women (in doses approximating testosterone concentrations for premenopausal women), is associated with mild increases in acne and body/facial hair growth in some women, but not with alopecia, clitoromegaly, or voice change. Short-term transdermal therapy also does not seem to affect breast cancer risk or have any significant effects on lipid profiles, the statement says.

The panel points out, however, that randomized controlled trials with testosterone therapy have excluded women who are at high risk of cardiometabolic disease, and that women with a previous diagnosis of breast cancer have also been excluded from randomized trials of testosterone in women with HSDD. This is a “big issue,” said Dr. Wierman, and means that recommendations regarding the effect of testosterone in postmenopausal women with HSDD may not be generalizable to possible at-risk subpopulations.

The panel endorsed testosterone therapy specifically for women with HSDD because most of the studies reporting on sexual function have recruited women with diagnosed HSDD. Demonstrated benefits of testosterone in these cases include improved sexual desire, arousal, orgasm, and pleasure, and reduced concerns and distress about sex. HSDD should be diagnosed after formal biopsychosocial assessment, the statement notes.

“We don’t completely understand the control of sexual function in women, but it’s very dependent on estrogen status. And it’s also dependent on psychosocial factors, emotional health, relationship issues, and physical issues,” Dr. Wierman said in the interview.

“In practice, we look at all these issues, and we first optimize estrogen status. Once that’s done, and we’ve looked at all the other components of sexual function, then we can consider off-label use of testosterone,” she said. “If there’s no response in 3-6 months, we stop it.”

Testosterone levels do not correlate with sexual dysfunction, Dr. Wierman emphasized, and direct assays for the measurement of total and free testosterone are unreliable. The statement acknowledges that but still recommends measurement of testosterone using direct assays, in cases in which liquid/gas chromatography and tandem mass spectrometry assay (which has “high accuracy and reproducibility”) are not available. This is “to exclude high baseline concentrations and also to exclude supraphysiological concentrations during treatment,” the panel said.

Most endocrinologists and other experts who prescribe testosterone therapy for women use an approved male formulation off label and adjust it – an approach that the panel says is reasonable as long as hormone concentrations are “maintained in the physiologic female range.”

Compounded “bioidentical” testosterone therapy “cannot be recommended for the treatment of HSDD because of the lack of evidence for safety and efficacy,” the statement says.

“A big concern of many endocrinologists,” Dr. Wierman added, “is the recent explosion of using pharmacological levels of both estrogen and testosterone in either [injections] or pellets.” The Endocrine Society and other societies have alerted the Food and Drug Administration to “this new cottage industry, which may have significant side effects and risks for our patients,” she said.

A new international position statement on testosterone therapy for women concludes that a trial of testosterone is appropriate for postmenopausal women with hypoactive sexual desire dysfunction (HSDD) and that its use for any other condition, symptom, or reason is not supported by available evidence.

The seven-page position statement, developed by an international task force of experts from the Endocrine Society, the American College of Gynecologists and Obstetricians, and multiple other medical societies, also emphasized that blood concentrations of testosterone should approximate premenopausal physiological conditions.

“When testosterone therapy is given, the resultant blood levels should not be above those seen in healthy young women,” said lead author Susan Ruth Davis, PhD, MBBS, of Monash University in Melbourne, Australia, in a press release issued by the Endocrine Society. Dr. Davis is president of the International Menopause Society, which coordinated the panel.

The statement was published in the Journal of Clinical Endocrinology & Metabolism and three other medical journals.

Margaret E. Wierman, MD, who represented the Endocrine Society on the task force, said in an interview that there has been “growing concern about testosterone being prescribed for a variety of signs and symptoms without data to support” such use. At the same time, there is significant concern about the ongoing lack of approved formulations licensed specifically for women, she said.

In part, the statement is about a renewed “call to industry to make some [female-specific] formulations so that we can examine other potential roles of testosterone in women,” said Dr. Wierman, professor of medicine and physiology at the University of Colorado at Denver, Aurora, and chief of endocrinology at the Rocky Mountain Regional Veterans Affairs Medical Center in Aurora.

“Testosterone may be useful [for indications other than HSDD], but we don’t know. There may be no [breast or cardiovascular disease risk], but we don’t know,” she said. “And without a formulation to study potential benefits and risks, it’s good to be cautious. It’s good to really outline where we have data and where we don’t.”

The Endocrine Society’s 2014 clinical practice guideline on androgen therapy in women, for which Dr. Wierman was the lead author, also recommended against the off-label use of testosterone for sexual dysfunction other than HSDD or for any other reason, such as cognitive, cardiovascular, metabolic, or bone health. As with the new statement, the society’s position statement was guided by an international, multisociety task force, albeit a smaller one.

For the new global position statement, the task force’s review of evidence includes a recently published systematic review and meta-analysis of randomized controlled trial data – of at least 12 weeks’ duration – on the use of testosterone for sexual function, cardiometabolic variables, cognitive measures, and musculoskeletal health. Some of the data from the randomized controlled trials were unpublished.

The meta-analysis, led by Dr. Davis and published in July in the Lancet Diabetes & Endocrinology, found that, compared with placebo or a comparator (such as estrogen, with or without progesterone), testosterone in either oral or transdermal form significantly improved sexual function in postmenopausal women. However, data about the effects of testosterone for other indications, its long-term safety, and its use in premenopausal women, were insufficient for drawing any conclusions (Lancet Diabetes Endocrinol. 2019 Jul 25. doi: 10.1016/S2213-8587[19]30189-5).

Postmenopausal women with a first-degree family history of diabetes (FHD) had higher bone mineral density (BMD) than did those without such a history, according to results of a study.

Lijuan Yang, MD, of First Affiliated Hospital of Wenzhou (China) Medical University and colleagues reported the results in Menopause. The cross-sectional study included 892 normoglycemic postmenopausal women, of whom 147 had a first-degree FHD; the mean age was 55 years among both those with and those without first-degree FHD. The investigators assessed BMDs of the femoral neck and lumbar spine with dual-energy x-ray absorptiometry and insulin resistance with Homeostasis Model Assessment of Insulin Resistance (HOMA-IR).

Lumbar spine BMD was higher in those with first-degree FHD than in those without, at 1.077 and 1.034 g/cm², respectively; femoral neck BMD was similarly higher at 0.89 vs. 0.85 g/cm², respectively. HOMA-IR also was higher among those with first-degree FHD than among those without, at 1.85 and 1.60, respectively.

Spearman’s correlation analyses showed that lumbar spine BMD was positively associated with first-degree FHD (P = .008) and HOMA-IR (P = .041), as was femoral neck BMD (P = .013 and P = .005, respectively). Results of multiple stepwise regression analysis showed that first-degree FHD and HOMA-IR were independent factors positively associated with femoral neck BMD (P = .029 and P = .0009, respectively) and lumbar spine BMD (P = .029 and P = .002).

“The present study demonstrated that lumbar spine BMD and femoral neck BMD were positively associated with HOMA-IR in postmenopausal women and that individuals with a first-degree FHD were more likely to have high HOMA-IR,” the investigators said. “We suggest that the elevated BMD in individuals with a first-degree FHD could be attributed to insulin resistance,” which appears to be inherited by persons with a first-degree FHD.

The authors noted that the cross-sectional design is a limitations of this study. They suggested future studies might investigate the relationship between insulin resistance and bone development in these populations by assessing osteocalcin and P1NP.

The study received funding or support from National Key R&D Program of China and from the Wenzhou Science & Technology Bureau. The authors did not disclose any conflicts of interest.

CASE HT for vasomotor symptoms in perimenopausal woman with cognitive concerns

Jackie is a 49-year-old woman. Her body mass index is 33 kg/m², and she has mild hypertension that is effectively controlled with antihypertensive medications. Otherwise, she is in good health.During her annual gynecologic exam, she reports that for the past 9 months her menstrual cycles have not been as regular as they used to be and that 3 months ago she skipped a cycle. She is having bothersome vasomotor symptoms (VMS) and is concerned about her memory. She says she is forgetful at work and in social situations. During a recent presentation, she could not remember the name of one of her former clients. At a work happy hour, she forgot the name of her coworker’s husband, although she did remember it later after returning home.

Her mother has Alzheimer disease (AD), and Jackie worries about whether she, too, might be developing dementia and whether her memory will fail her in social situations.

She is concerned about using hormone therapy (HT) for her vasomotor symptoms because she has heard that it can lead to breast cancer and/or AD.

How would you advise her?

HT remains the most effective treatment for bothersome VMS, but concerns about its cognitive safety persist. Such concerns, and indeed a black-box warning about the risk of dementia with HT use, initially arose following the 2003 publication of the Women’s Health Initiative Memory Study (WHIMS), a randomized, placebo-controlled trial of HT for the primary prevention of dementia in women aged 65 years and older at baseline.¹ The study found that combination estrogen/progestin therapy was associated with a 2-fold increase in dementia when compared with placebo.

One of the critical questions arising even before WHIMS was whether the cognitive risks associated with HT that were seen in WHIMS apply to younger women. Attempting to answer the question and adding fuel to the fire are the results of a recent case-control study from Finland.² This study compared HT use in Finnish women with and without AD and found that HT use was higher among Finnish women with AD compared with those without AD, regardless of age. The authors concluded, “Our data must be implemented into information for the present and future users of HT, even though the absolute risk increase is small.”

However, given the limitations inherent to observational and registry studies, and the contrasting findings of 3 high-quality, randomized controlled trials (RCTs; more details below), providers actually can reassure younger peri- and postmenopausal women about the cognitive safety of HT.³ They also can explain to patients that cognitive symptoms like the ones described in the case example are normal and provide general guidance to midlife women on how to optimize brain health.

Closer look at WHI and RCT research pinpoints cognitively neutral HT

In WHIMS, the combination of conjugated equine estrogen (CEE; 0.625 mg/d) plus medroxyprogesterone acetate (MPA; 2.5 mg/d) led to a doubling of the risk of all-cause dementia compared with placebo in a sample of 4,532 women aged 65 years and older at baseline.¹ CEE alone (0.625 mg) did not lead to an increased risk of all-cause dementia.⁴

Whether those formulations led to cognitive impairment in younger postmenopausal women was the focus of WHIMS-Younger (WHIMS-Y), which involved WHI participants aged 50 to 55 years at baseline.⁵ Results revealed neutral cognitive effects (ie, no differences in cognitive performance in women randomly assigned to HT or placebo) in women tested 7.2 years after the end of the WHI trial. WHIMS-Y findings indicated that there were no sustained cognitive risks of CEE or CEE/MPA therapy. Two randomized, placebo-controlled trials involving younger postmenopausal women yielded similar findings.^6,7 HT shown to produce cognitively neutral effects during active treatment included transdermal estradiol plus micronized progesterone,⁶ CEE plus progesterone,⁶ and oral estradiol plus vaginal progesterone gel.⁷ The findings of these randomized trials are critical for guiding decisions regarding the cognitive risks of HT in early postmenopausal women (TABLE 1).

What about women with VMS?

A key gap in knowledge about the cognitive effects of HT is whether HT confers cognitive advantages to women with bothersome VMS. This is a striking absence given that the key indication for HT is the treatment of VMS. While some symptomatic women were included in the trials of HT in younger postmenopausal women described above, no large trial to date has selectively enrolled women with moderate-to-severe VMS to determine if HT is cognitively neutral, beneficial, or detrimental in that group. Some studies involving midlife women have found associations between VMS (as measured with ambulatory skin conductance monitors) and multiple measures of brain health, including memory performance,⁸ small ischemic lesions on structural brain scans,⁹ and altered brain function.¹⁰ In a small trial of a nonhormonal intervention for VMS, improvement in VMS following the intervention was directly related to improvement in memory performance.¹¹ The reliability of these findings continues to be evaluated but raises the hypothesis that VMS treatments might improve memory in midlife women.

Memory complaints common among midlife women

About 60% of women report an undesirable change in memory performance at midlife as compared with earlier in their lives.^12,13 Complaints of forgetfulness are higher in perimenopausal and postmenopausal women compared with premenopausal women, even when those women are similar in age.¹⁴ Two large prospective studies found that memory performance decreases during the perimenopause and then rebounds, suggesting a transient decrease in memory.^15,16 Although cognitive complaints are common among women in their 40s and 50s, AD is rare in that age group. The risk is largely limited to those women with a parent who developed dementia before age 65, as such cases suggest a familial form of AD.

What causes cognitive difficulties during midlife?

First, some cognitive decline is expected at midlife based on increasing age. Second, above and beyond the role of chronologic aging (ie, getting one year older each year), ovarian aging plays a role. A role of estrogen was verified in clinical trials showing that memory decreased following oophorectomy in premenopausal women in their 40s but returned to presurgical levels following treatment with estrogen therapy (ET).¹⁷ Cohort studies indicate that women who undergo oophorectomy before the typical age of menopause are at increased risk for cognitive impairment or dementia, but those who take ET after oophorectomy until the typical age of menopause do not show that risk.¹⁸

Third, cognitive problems are linked not only to VMS but also to sleep disturbance, depressed mood, and increased anxiety—all of which are common in midlife women.^15,19 Lastly, health factors play a role. Hypertension, obesity, insulin resistance, diabetes, and smoking are associated with adverse brain changes at midlife.²⁰

Giving advice to your patients

First, normalize the cognitive complaints, noting that some cognitive changes are an expected part of aging for all people regardless of whether they are male or female. Advise that while the best studies indicate that these cognitive lapses are especially common in perimenopausal women, they appear to be temporary; women are likely to resume normal cognitive function once the hormonal changes associated with menopause subside.^15,16 Note that the one unknown is the role that VMS play in memory problems and that some studies indicate a link between VMS and cognitive problems. Women may experience some cognitive improvement if VMS are effectively treated.

Advise patients that the Endocrine Society, the North American Menopause Society (NAMS), and the International Menopause Society all have published guidelines saying that the benefits of HT outweigh the risks for most women aged 50 to 60 years.²¹ For concerns about the cognitive adverse effects of HT, discuss the best quality evidence—that which comes from randomized trials—which shows no harmful effects of HT in midlife women.^5-7 Especially reassuring is that one of these high-quality studies was conducted by the same researchers who found that HT can be risky in older women (ie, the WHI Investigators).⁵

Going one step further: Protecting brain health

As primary care providers to midlife women, ObGyns can go one step further and advise patients on how to proactively nurture their brain health. Great evidence-based resources for information on maintaining brain health include the Alzheimer’s Association (https://www.alz.org) and the Women’s Brain Health Initiative (https://womensbrainhealth.org). Primary prevention of AD begins decades before the typical age of an AD diagnosis, and many risk factors for AD are modifiable.²² Patients can keep their brains healthy through myriad approaches including treating hypertension, reducing body mass index, engaging in regular aerobic exercise (brisk walking is fine), eating a Mediterranean diet, maintaining an active social life, and engaging in novel challenging activities like learning a new language or a new skill like dancing.²⁰

Also important is the overlap between cognitive issues, mood, and alcohol use. In the opening case, Jackie mentions alcohol use and social withdrawal. According to the National Institute on Alcohol Abuse and Alcoholism (NIAAA), low-risk drinking for women is defined as no more than 3 drinks on any single day and no more than 7 drinks per week.²³ Heavy alcohol use not only affects brain function but also mood, and depressed mood can lead women to drink excessively.²⁴

In addition, Jackie’s mother has AD, and that stressor can contribute to depressed feelings, especially if Jackie is involved in caregiving. A quick screen for depression with an instrument like the Patient Health Questionnaire-2 (PHQ-2; TABLE 2)²⁵ can rule out a more serious mood disorder—an approach that is particularly important for patients with a history of major depression, as 58% of those patients experience a major depressive episode during the menopausal transition.²⁶ For this reason, it is important to ask patients like Jackie if they have a history of depression; if they do and were treated medically, consider prescribing the antidepressant that worked in the past. For information on menopause and mood-related issues, providers can access new guidelines from NAMS and the National Network of Depression Centers (NNDC).²⁷ There is also a handy patient information sheet to accompany those guidelines on the NAMS website (https://www.menopause.org/).

CASE Resolved

When approaching Jackie, most importantly, I would normalize her experience and tell her that memory problems are common in the menopausal transition, especially for women with bothersome VMS. Research suggests that the memory problems she is experiencing are related to hormonal changes and not to AD, and that her memory will likely improve once she has transitioned through the menopause. I would tell her that AD is rare at midlife unless there is a family history of early onset of AD (before age 65), and I would verify the age at which her mother was diagnosed to confirm that it was late-onset AD.

For now, I would recommend that she be prescribed HT for her bothersome hot flashes using one of the “safe” formulations in the Table on page 24. I also would tell her that there is much she can do to lower her risk of AD and that it is best to start now as she enters her 50s because that is when AD changes typically start in the brain, and she can start to prevent those changes now.

I would tell her that experts in the field of AD agree that these lifestyle interventions are currently the best way to prevent AD and that the more of them she engages in, the more her brain will benefit. I would advise her to continue to manage her hypertension and to consider ways of lowering her BMI to enhance her brain health. Engaging in regular brisk walking or other aerobic exercise, as well as incorporating more of the Mediterranean diet into her daily food intake would also benefit her brain. As a working woman, she is exercising her brain, and she should consider other cognitively challenging activities to keep her brain in good shape.

I would follow up with her in a few months to see if her memory functioning is better. If it is not, and if her VMS continue to be bothersome, I would increase her dose of HT. Only if her VMS are treated but her memory problems are getting worse would I screen her with a Mini-Mental State Exam and refer her to a neurologist for an evaluation.
 

CASE HT for vasomotor symptoms in perimenopausal woman with cognitive concerns

Jackie is a 49-year-old woman. Her body mass index is 33 kg/m², and she has mild hypertension that is effectively controlled with antihypertensive medications. Otherwise, she is in good health.During her annual gynecologic exam, she reports that for the past 9 months her menstrual cycles have not been as regular as they used to be and that 3 months ago she skipped a cycle. She is having bothersome vasomotor symptoms (VMS) and is concerned about her memory. She says she is forgetful at work and in social situations. During a recent presentation, she could not remember the name of one of her former clients. At a work happy hour, she forgot the name of her coworker’s husband, although she did remember it later after returning home.

Her mother has Alzheimer disease (AD), and Jackie worries about whether she, too, might be developing dementia and whether her memory will fail her in social situations.

She is concerned about using hormone therapy (HT) for her vasomotor symptoms because she has heard that it can lead to breast cancer and/or AD.

How would you advise her?

HT remains the most effective treatment for bothersome VMS, but concerns about its cognitive safety persist. Such concerns, and indeed a black-box warning about the risk of dementia with HT use, initially arose following the 2003 publication of the Women’s Health Initiative Memory Study (WHIMS), a randomized, placebo-controlled trial of HT for the primary prevention of dementia in women aged 65 years and older at baseline.¹ The study found that combination estrogen/progestin therapy was associated with a 2-fold increase in dementia when compared with placebo.

One of the critical questions arising even before WHIMS was whether the cognitive risks associated with HT that were seen in WHIMS apply to younger women. Attempting to answer the question and adding fuel to the fire are the results of a recent case-control study from Finland.² This study compared HT use in Finnish women with and without AD and found that HT use was higher among Finnish women with AD compared with those without AD, regardless of age. The authors concluded, “Our data must be implemented into information for the present and future users of HT, even though the absolute risk increase is small.”

However, given the limitations inherent to observational and registry studies, and the contrasting findings of 3 high-quality, randomized controlled trials (RCTs; more details below), providers actually can reassure younger peri- and postmenopausal women about the cognitive safety of HT.³ They also can explain to patients that cognitive symptoms like the ones described in the case example are normal and provide general guidance to midlife women on how to optimize brain health.

Closer look at WHI and RCT research pinpoints cognitively neutral HT

In WHIMS, the combination of conjugated equine estrogen (CEE; 0.625 mg/d) plus medroxyprogesterone acetate (MPA; 2.5 mg/d) led to a doubling of the risk of all-cause dementia compared with placebo in a sample of 4,532 women aged 65 years and older at baseline.¹ CEE alone (0.625 mg) did not lead to an increased risk of all-cause dementia.⁴

Whether those formulations led to cognitive impairment in younger postmenopausal women was the focus of WHIMS-Younger (WHIMS-Y), which involved WHI participants aged 50 to 55 years at baseline.⁵ Results revealed neutral cognitive effects (ie, no differences in cognitive performance in women randomly assigned to HT or placebo) in women tested 7.2 years after the end of the WHI trial. WHIMS-Y findings indicated that there were no sustained cognitive risks of CEE or CEE/MPA therapy. Two randomized, placebo-controlled trials involving younger postmenopausal women yielded similar findings.^6,7 HT shown to produce cognitively neutral effects during active treatment included transdermal estradiol plus micronized progesterone,⁶ CEE plus progesterone,⁶ and oral estradiol plus vaginal progesterone gel.⁷ The findings of these randomized trials are critical for guiding decisions regarding the cognitive risks of HT in early postmenopausal women (TABLE 1).

What about women with VMS?

A key gap in knowledge about the cognitive effects of HT is whether HT confers cognitive advantages to women with bothersome VMS. This is a striking absence given that the key indication for HT is the treatment of VMS. While some symptomatic women were included in the trials of HT in younger postmenopausal women described above, no large trial to date has selectively enrolled women with moderate-to-severe VMS to determine if HT is cognitively neutral, beneficial, or detrimental in that group.

Postmenopausal bleeding (PMB) is the presenting sign in most cases of endometrial carcinoma. Prompt evaluation of PMB can exclude, or diagnose, endometrial carcinoma.¹ Although no general consensus exists for PMB evaluation, it involves endometrial assessment with transvaginal ultrasonography (TVUS) and subsequent endometrial biopsy when a thickened endometrium is found. When biopsy results reveal insufficient or scant tissue, further investigation into the etiology of PMB should include office hysteroscopy with possible directed biopsy. In this article I discuss the prevalence of PMB and steps for evaluation, providing clinical takeaways.

Postmenopausal bleeding: Its risk for cancer

Abnormal uterine bleeding (AUB) in a postmenopausal woman is of particular concern to the gynecologist and the patient because of the increased possibility of endometrial carcinoma in this age group. AUB is present in more than 90% of postmenopausal women with endometrial carcinoma, which leads to diagnosis in the early stages of the disease. Approximately 3% to 7% of postmenopausal women with PMB will have endometrial carcinoma.² Most women with PMB, however, experience bleeding secondary to atrophic changes of the vagina or endometrium and not to endometrial carcinoma. (FIGURE 1, VIDEO 1) In addition, women who take gonadal steroids for hormone replacement therapy (HRT) may experience breakthrough bleeding that leads to initial investigation with TVUS.

Video 1

Vidyard Video

The risk of malignancy in polyps in postmenopausal women over the age of 59 who present with PMB is approximately 12%, and hysteroscopic resection should routinely be performed. For asymptomatic patients, the risk of a malignant lesion is low—approximately 3%—and for these women intervention should be assessed individually for the risks of carcinoma and benefits of hysteroscopic removal.³

Clinical takeaway. The high possibility of endometrial carcinoma in postmenopausal women warrants that any patient who is symptomatic with PMB should be presumed to have endometrial cancer until the diagnostic evaluation process proves she does not.

Evaluation of postmenopausal bleeding

Transvaginal ultrasound

As mentioned, no general consensus exists for the evaluation of PMB; however, initial evaluation by TVUS is recommended. The American College of Obstetricians and Gynecologists (ACOG) concluded that when the endometrium measures ≤4 mm with TVUS, the likelihood that bleeding is secondary to endometrial carcinoma is less than 1% (negative predictive value 99%), and endometrial biopsy is not recommended.³ Endometrial sampling in this clinical scenario likely will result in insufficient tissue for evaluation, and it is reasonable to consider initial management for atrophy. A thickened endometrium on TVUS (>4 mm in a postmenopausal woman with PMB) warrants additional evaluation with endometrial sampling (FIGURE 2).

Clinical takeaway. A thickened endometrium on TVUS ≥4 mm in a postmenopausal woman with PMB warrants additional evaluation with endometrial sampling.

Endometrial biopsy

An endometrial biopsy is performed to determine whether endometrial cancer or precancer is present in women with AUB. ACOG recommends that endometrial biopsy be performed for women older than age 45. It is also appropriate in women younger than 45 years if they have risk factors for developing endometrial cancer, including unopposed estrogen exposure (obesity, ovulatory dysfunction), failed medical management of AUB, or persistence of AUB.⁴

Continue to: Endometrial biopsy has some...

 

 

Endometrial biopsy has some diagnostic shortcomings, however. In 2016 a systematic review and meta-analysis found that, in women with PMB, the specificity of endometrial biopsy was 98% to 100% (accurate diagnosis with a positive result). The sensitivity (ability to make an accurate diagnosis) of endometrial biopsy to identify endometrial pathology (carcinoma, atypical hyperplasia, and polyps) is lower than typically thought. These investigators found an endometrial biopsy failure rate of 11% (range, 1% to 53%) and rate of insufficient samples of 31% (range, 7% to 76%). In women with insufficient or failed samples, endometrial cancer or precancer was found in 7% (range, 0% to 18%).⁵ Therefore, a negative tissue biopsy result in women with PMB is not considered to be an endpoint, and further evaluation with hysteroscopy to evaluate for focal disease is imperative. The results of endometrial biopsy are only an endpoint to the evaluation of PMB when atypical hyperplasia or endometrial cancer is identified.

Clinical takeaway. A negative tissue biopsy result in women with PMB is not considered to be an endpoint, and further evaluation with hysteroscopy to evaluate for focal disease is imperative.

 

Hysteroscopy

Hysteroscopy is the gold standard for evaluating the uterine cavity, diagnosing intrauterine pathology, and operative intervention for some causes of AUB. It also is easily performed in the office. This makes the hysteroscope an essential instrument for the gynecologist. Dr. Linda Bradley, a preeminent leader in hysteroscopic surgical education, has coined the phrase, “My hysteroscope is my stethoscope.”⁶ As gynecologists, we should be as adept at using a hysteroscope in the office as the cardiologist is at using a stethoscope.

It has been known for some time that hysteroscopy improves our diagnostic capabilities over blinded procedures such as endometrial biopsy and dilation and curettage (D&C). As far back as 1989, Dr. Frank Loffer reported the increased sensitivity (ability to make an accurate diagnosis) of hysteroscopy with directed biopsy over blinded D&C (98% vs 65%) in the evaluation of AUB.⁷ Evaluation of the endometrium with D&C is no longer recommended; yet today, few gynecologists perform hysteroscopic-directed biopsy for AUB evaluation instead of blinded tissue sampling despite the clinical superiority and in-office capabilities (FIGURE 3).

Hysteroscopy and endometrial carcinoma

The most common type of gynecologic cancer in the United States is endometrial adenocarcinoma (type 1 endometrial cancer). There is some concern about the effect of hysteroscopy on endometrial cancer prognosis and the spread of cells to the peritoneum at the time of hysteroscopy. A large meta-analysis found that hysteroscopy performed in the presence of type 1 endometrial cancer statistically significantly increased the likelihood of positive intraperitoneal cytology; however, it did not alter the clinical outcome. It was recommended that hysteroscopy not be avoided for this reason and is helpful in the diagnosis of endometrial cancer, especially in the early stages of disease.⁸

For endometrial cancer type 2 (serous carcinoma, clear cell carcinoma, and carcinosarcoma), Chen and colleagues reported a statistically significant increase in positive peritoneal cytology for cancers evaluated by hysteroscopy versus D&C. The disease-specific survival for the hysteroscopy group was 60 months, compared with 71 months for the D&C group. While this finding was not statistically significant, it was clinically relevant, and the effect of hysteroscopy on prognosis with type 2 endometrial cancer is unclear.⁹

Three clinical scenarios

---

A common occurrence in the evaluation of postmenopausal bleeding (PMB) is an initial TVUS finding of an enlarged endometrium and an endometrial biopsy that is negative or reveals scant or insufficient tissue. Unfortunately, the diagnostic evaluation process often stops here, and a diagnosis for the PMB is never actually identified. Here are several clinical scenarios that highlight the need for hysteroscopy in the initial evaluation of PMB, especially when there is a discordance between transvaginal ultrasonography (TVUS) and endometrial biopsy findings.

Patient 1: Discordant TVUS and biopsy, with benign findings

The patient is a 52-year-old woman who presented to her gynecologist reporting abnormal uterine bleeding (AUB). She has a history of breast cancer, and she completed tamoxifen treatment. Pelvic ultrasonography was performed; an enlarged endometrial stripe of 1.3 cm was found (FIGURE 4A). Endometrial biopsy was performed, showing adequate tissue but with a negative result. The patient is told that she is likely perimenopausal, which is the reason for her bleeding.

At the time of referral, the patient is evaluated with in-office hysteroscopy. Diagnosis of a 5 cm x 7 cm benign endometrial polyp is made. An uneventful hysteroscopic polypectomy is performed (VIDEO 2).

This scenario illustrates the shortcoming of initial evaluation by not performing a hysteroscopy, especially in a woman with a thickened endometrium with previous tamoxifen therapy. Subsequent visits failed to correlate bleeding etiology with discordant TVUS and endometrial biopsy results with hysteroscopy, and no hysteroscopy was performed in the operating room at the time of D&C.

Patient 2: Discordant TVUS and biopsy, with premalignant findings

The patient is a 62-year-old woman who had incidental findings of a thickened endometrium on computed tomography scan of the pelvis. TVUS confirmed a thickened endometrium measuring 17 mm, and an endometrial biopsy showed scant tissue.

At the time of referral, a diagnostic hysteroscopy was performed in the office. Endometrial atrophy, a large benign appearing polyp, and focal abnormal appearing tissue were seen (FIGURE 5). A decision for polypectomy and directed biopsy was made. Histology findings confirmed benign polyp and atypical hyperplasia (VIDEO 3).

This scenario illustrates that while the patient was asymptomatic, there was discordance between the TVUS and endometrial biopsy. Hysteroscopy identified a benign endometrial polyp, which is common in asymptomatic postmenopausal patients with a thickened endometrium and endometrial biopsy showing scant tissue. However, addition of the diagnostic hysteroscopy identified focal precancerous tissue, removed under directed biopsy.

Patient 3: Discordant TVUS and biopsy, with malignant findings

The patient is a 68-year-old woman with PMB. TVUS showed a thickened endometrium measuring 14 mm. An endometrial biopsy was negative, showing scant tissue. No additional diagnostic evaluation or management was offered.

At the time of referral, the patient was evaluated with in-office diagnostic hysteroscopy, and the patient was found to have endometrial atrophy, benign appearing polyps, and focal abnormal tissue (FIGURE 6). A decision for polypectomy and directed biopsy was made. Histology confirmed benign polyps and grade 1 adenocarcinoma (VIDEOS 4A, 4B, 4C).

Conclusion

Evaluation of PMB begins with a screening TVUS. Findings of an endometrium of ≤4 mm indicate a very low likelihood of the presence of endometrial cancer, and treatment for atrophy or changes to hormone replacement therapy regimen is reasonable first-line management; endometrial biopsy is not recommended. For patients with persistent PMB or thickened endometrium ≥4 mm on TVUS, biopsy sampling of the endometrium should be performed. If the endometrial biopsy does not explain the etiology of the PMB with atypical hyperplasia or endometrial cancer, then hysteroscopy should be performed to evaluate for focal endometrial disease and possible directed biopsy.

Postmenopausal bleeding (PMB) is the presenting sign in most cases of endometrial carcinoma. Prompt evaluation of PMB can exclude, or diagnose, endometrial carcinoma.¹ Although no general consensus exists for PMB evaluation, it involves endometrial assessment with transvaginal ultrasonography (TVUS) and subsequent endometrial biopsy when a thickened endometrium is found. When biopsy results reveal insufficient or scant tissue, further investigation into the etiology of PMB should include office hysteroscopy with possible directed biopsy. In this article I discuss the prevalence of PMB and steps for evaluation, providing clinical takeaways.

Postmenopausal bleeding: Its risk for cancer

Abnormal uterine bleeding (AUB) in a postmenopausal woman is of particular concern to the gynecologist and the patient because of the increased possibility of endometrial carcinoma in this age group. AUB is present in more than 90% of postmenopausal women with endometrial carcinoma, which leads to diagnosis in the early stages of the disease. Approximately 3% to 7% of postmenopausal women with PMB will have endometrial carcinoma.² Most women with PMB, however, experience bleeding secondary to atrophic changes of the vagina or endometrium and not to endometrial carcinoma. (FIGURE 1, VIDEO 1) In addition, women who take gonadal steroids for hormone replacement therapy (HRT) may experience breakthrough bleeding that leads to initial investigation with TVUS.

The risk of malignancy in polyps in postmenopausal women over the age of 59 who present with PMB is approximately 12%, and hysteroscopic resection should routinely be performed. For asymptomatic patients, the risk of a malignant lesion is low—approximately 3%—and for these women intervention should be assessed individually for the risks of carcinoma and benefits of hysteroscopic removal.³

Clinical takeaway. The high possibility of endometrial carcinoma in postmenopausal women warrants that any patient who is symptomatic with PMB should be presumed to have endometrial cancer until the diagnostic evaluation process proves she does not.

Evaluation of postmenopausal bleeding

Transvaginal ultrasound

As mentioned, no general consensus exists for the evaluation of PMB; however, initial evaluation by TVUS is recommended. The American College of Obstetricians and Gynecologists (ACOG) concluded that when the endometrium measures ≤4 mm with TVUS, the likelihood that bleeding is secondary to endometrial carcinoma is less than 1% (negative predictive value 99%), and endometrial biopsy is not recommended.³ Endometrial sampling in this clinical scenario likely will result in insufficient tissue for evaluation, and it is reasonable to consider initial management for atrophy. A thickened endometrium on TVUS (>4 mm in a postmenopausal woman with PMB) warrants additional evaluation with endometrial sampling (FIGURE 2).

Clinical takeaway. A thickened endometrium on TVUS ≥4 mm in a postmenopausal woman with PMB warrants additional evaluation with endometrial sampling.

Endometrial biopsy

An endometrial biopsy is performed to determine whether endometrial cancer or precancer is present in women with AUB. ACOG recommends that endometrial biopsy be performed for women older than age 45. It is also appropriate in women younger than 45 years if they have risk factors for developing endometrial cancer, including unopposed estrogen exposure (obesity, ovulatory dysfunction), failed medical management of AUB, or persistence of AUB.⁴

Endometrial biopsy has some diagnostic shortcomings, however. In 2016 a systematic review and meta-analysis found that, in women with PMB, the specificity of endometrial biopsy was 98% to 100% (accurate diagnosis with a positive result). The sensitivity (ability to make an accurate diagnosis) of endometrial biopsy to identify endometrial pathology (carcinoma, atypical hyperplasia, and polyps) is lower than typically thought. These investigators found an endometrial biopsy failure rate of 11% (range, 1% to 53%) and rate of insufficient samples of 31% (range, 7% to 76%).

LOS ANGELES – Estrogen therapy may have scored another goal in its comeback game, as a 7-year prospective study shows that a transdermal formulation preserves some measures of cognitive function and brain architecture in postmenopausal women.

JackF/thinkstockphotos.com

In addition to performing better on subjective tests of memory, women using the estrogen patch experienced less cortical atrophy and were less likely to show amyloid on brain imaging. The observations were moderately associated with the improved sleep these women reported, Burcu Zeydan, MD, said at the Alzheimer’s Association International Conference.

“By 7 years, among the cognitive domains studied ... [less brain and cognitive change] correlated with lower global sleep score, meaning better sleep quality in the estradiol group,” said Dr. Zeydan, assistant professor of radiology at the Mayo Clinic in Rochester, Minn. “We previously found that preservation of dorsolateral prefrontal cortex over 7 years was associated with lower cortical beta-amyloid deposition on PET only in the estradiol group, pointing out the potential role of estrogen receptors in modulating this relationship.”

Dysregulated sleep is more common among women than men, particularly as menopause approaches and estrogen levels fluctuate, then decline, Dr. Zeydan said.

Dr. Zeydan reported the sleep substudy of KEEPS (the Kronos Early Estrogen Prevention Study), a randomized, double-blind, placebo-controlled, multisite trial that compared oral conjugated equine estrogen with transdermal estradiol. A control group received oral placebo and a placebo patch.*

Brain architecture was similar between the placebo and transdermal groups, but it was actually worse in some measures in the oral-estrogen group, compared with the placebo group. Women taking oral estrogen had more white matter hyperintensities, greater ventricle enlargement, and more cortical thinning. Those differences resolved after they stopped taking the oral formulation, bringing them into line with the transdermal and placebo groups.

The investigation also found that the transdermal group showed lower cerebral amyloid binding on PET scans relative to both placebo and oral estrogen.

“The relative preservation of dorsolateral prefrontal cortical volume in the [transdermal estradiol] group over 7 years indicates that hormone therapy may have long-term effects on the brain,” the team concluded. They noted that the original KEEPS study didn’t find any cognitive correlation with these changes.

The subanalysis looked at 69 women of the KEEPS cohort who had been followed for the full 7 years (4 years on treatment and 3 years off treatment). They were randomized to oral placebo and a placebo patch,* oral conjugated equine estrogen (0.45 mg/day), or transdermal estradiol (50 mcg/day). Participants in the active treatment groups received oral micronized progesterone 12 days each month. All had complete data on cognitive testing and brain imaging. Sleep quality was measured by the Pittsburgh Sleep Quality Index. Dr. Zeydan compared cognition and brain architecture findings in relation to the sleep score; lower scores mean better sleep.

The women were aged 42-58 years at baseline, and within 36 months from menopause. They had no history of menopausal hormone therapy or cardiovascular disease.

The investigators were particularly interested in how estrogen might have modulated the disturbed sleep patterns that often accompany perimenopause and early menopause, and whether the observed brain and cognitive changes tracked with sleep quality.

“During this time, 40% to 60% of women report problems sleeping, and estrogen decline seems to play an important role in sleep disturbances during this phase,” Dr. Zeydan said. “Although poor sleep quality is common in recently menopausal women, sleep quality improves with hormone therapy, as was previously demonstrated in KEEPS hormone therapy trial in recently menopausal women.”

By year 7, the cohort’s mean age was 61 years. The majority had at least some college education. The percentage who carried an apolipoprotein E epsilon-4 allele varied by group, with 15% positivity in the oral group, 48% in the transdermal group, and 16% in the placebo group.


Cognitive function was estimated with a global cognitive measure and four cognitive domain scores: verbal learning and memory, auditory attention and working memory, visual attention and executive function, and mental flexibility.

Higher attention and executive function scores were moderately correlated with a lower sleep score in the transdermal group (r = –0.54, a significant difference compared with the oral formulation). Lower sleep scores also showed a moderate correlation with preserved cortical volume of the dorsolateral prefrontal region (r = –0.47, also significantly different from the oral group).

Lower brain amyloid also positively correlated with better sleep. The correlation between sleep and global amyloid burden in the transdermal group was also moderate (r = 0.45), while the correlation in the oral group was significantly weaker (r = 0.18).

“We can say that sleep quality and transdermal estradiol during early postmenopausal years somehow interact to influence beta-amyloid deposition, preservation of dorsolateral prefrontal cortex volume, and attention and executive function,” Dr. Zeydan said.

Dr. Zeydan had no financial disclosures.

Brain architecture was similar between the placebo and transdermal groups, but it was actually worse in some measures in the oral-estrogen group, compared with the placebo group. Women taking oral estrogen had more white matter hyperintensities, greater ventricle enlargement, and more cortical thinning. Those differences resolved after they stopped taking the oral formulation, bringing them into line with the transdermal and placebo groups.

The investigation also found that the transdermal group showed lower cerebral amyloid binding on PET scans relative to both placebo and oral estrogen.

“The relative preservation of dorsolateral prefrontal cortical volume in the [transdermal estradiol] group over 7 years indicates that hormone therapy may have long-term effects on the brain,” the team concluded. They noted that the original KEEPS study didn’t find any cognitive correlation with these changes.

The subanalysis looked at 69 women of the KEEPS cohort who had been followed for the full 7 years (4 years on treatment and 3 years off treatment). They were randomized to oral placebo and a placebo patch,* oral conjugated equine estrogen (0.45 mg/day), or transdermal estradiol (50 mcg/day). Participants in the active treatment groups received oral micronized progesterone 12 days each month. All had complete data on cognitive testing and brain imaging. Sleep quality was measured by the Pittsburgh Sleep Quality Index. Dr. Zeydan compared cognition and brain architecture findings in relation to the sleep score; lower scores mean better sleep.

The women were aged 42-58 years at baseline, and within 36 months from menopause. They had no history of menopausal hormone therapy or cardiovascular disease.

The investigators were particularly interested in how estrogen might have modulated the disturbed sleep patterns that often accompany perimenopause and early menopause, and whether the observed brain and cognitive changes tracked with sleep quality.

“During this time, 40% to 60% of women report problems sleeping, and estrogen decline seems to play an important role in sleep disturbances during this phase,” Dr. Zeydan said. “Although poor sleep quality is common in recently menopausal women, sleep quality improves with hormone therapy, as was previously demonstrated in KEEPS hormone therapy trial in recently menopausal women.”

By year 7, the cohort’s mean age was 61 years. The majority had at least some college education. The percentage who carried an apolipoprotein E epsilon-4 allele varied by group, with 15% positivity in the oral group, 48% in the transdermal group, and 16% in the placebo group.


Cognitive function was estimated with a global cognitive measure and four cognitive domain scores: verbal learning and memory, auditory attention and working memory, visual attention and executive function, and mental flexibility.

Higher attention and executive function scores were moderately correlated with a lower sleep score in the transdermal group (r = –0.54, a significant difference compared with the oral formulation). Lower sleep scores also showed a moderate correlation with preserved cortical volume of the dorsolateral prefrontal region (r = –0.47, also significantly different from the oral group).

Lower brain amyloid also positively correlated with better sleep. The correlation between sleep and global amyloid burden in the transdermal group was also moderate (r = 0.45), while the correlation in the oral group was significantly weaker (r = 0.18).

“We can say that sleep quality and transdermal estradiol during early postmenopausal years somehow interact to influence beta-amyloid deposition, preservation of dorsolateral prefrontal cortex volume, and attention and executive function,” Dr. Zeydan said.

Dr. Zeydan had no financial disclosures.

LOS ANGELES – Estrogen therapy may have scored another goal in its comeback game, as a 7-year prospective study shows that a transdermal formulation preserves some measures of cognitive function and brain architecture in postmenopausal women.

In addition to performing better on subjective tests of memory, women using the estrogen patch experienced less cortical atrophy and were less likely to show amyloid on brain imaging. The observations were moderately associated with the improved sleep these women reported, Burcu Zeydan, MD, said at the Alzheimer’s Association International Conference.

“By 7 years, among the cognitive domains studied ... [less brain and cognitive change] correlated with lower global sleep score, meaning better sleep quality in the estradiol group,” said Dr. Zeydan, assistant professor of radiology at the Mayo Clinic in Rochester, Minn. “We previously found that preservation of dorsolateral prefrontal cortex over 7 years was associated with lower cortical beta-amyloid deposition on PET only in the estradiol group, pointing out the potential role of estrogen receptors in modulating this relationship.”

Postmenopausal breast cancer survivors are at greater risk for cardiovascular disease than are their peers without breast cancer, according to a new study of nearly 300 women.

Previous studies have shown that cardiovascular risk is greater among postmenopausal women treated for breast cancer compared with those without cancer, but specific risk factors have not been well studied, wrote Daniel de Araujo Brito Buttros, MD, of Paulista State University, Sao Paulo, Brazil, and colleagues.

In a study published in Menopause, the researchers evaluated several CVD risk factors in 96 postmenopausal women with breast cancer and 192 women without breast cancer, including metabolic syndrome, subclinical atherosclerosis, and heat shock proteins (HSP) 60 and 70.

Overall, breast cancer patients had significantly higher HSP60 levels and lower HSP70 levels than those of their cancer-free peers. These two proteins have an antagonistic relationship in cardiovascular disease, with HSP60 considered a risk factor for CVD, and HSP70 considered a protective factor. Average HSP60 levels for the breast cancer and control groups were 35 ng/mL and 10.8 ng/mL, respectively; average HSP70 levels were 0.5 ng/mL and 1.3 ng/mL, respectively.

Both diabetes and metabolic syndrome were significantly more common among breast cancer patients vs. controls (19.8% vs. 6.8% and 54.2% vs. 30.7%, respectively). Carotid artery plaque also was more common in breast cancer patients vs. controls (19.8% vs. 9.4%, respectively, P = 0.013).

In addition, systolic and diastolic blood pressure levels were significantly higher among the breast cancer patients, as were triglycerides and glucose.

The findings were limited by several factors including the cross-sectional design that could not prove a causal relationship between CVD risk and breast cancer, the researchers noted.

However, the results demonstrate the increased CVD risk for breast cancer patients, and “[therefore], women diagnosed with breast cancer might receive multidisciplinary care, including cardiology consultation at the time of breast cancer diagnosis and also during oncologic follow-up visits,” they said.

“Heart disease appears more commonly in women treated for breast cancer because of the toxicities of chemotherapy, radiation therapy, and use of aromatase inhibitors, which lower estrogen. Heart-healthy lifestyle modifications will decrease both the risk of recurrent breast cancer and the risk of developing heart disease,” JoAnn Pinkerton, MD, executive director of the North American Menopause Society, said in a statement. “Women should schedule a cardiology consultation when breast cancer is diagnosed and continue with ongoing follow-up after cancer treatments are completed,” she emphasized.

The researchers had no financial conflicts to disclose.
