TBD Meeting (3177-22)

Up to 10 different menopausal symptoms were linked to an increased risk of cardiovascular disease when they were moderate to severe in women who initially had no evidence of cardiovascular disease, according to research presented at the North American Menopause Society annual meeting in Atlanta.

“The take-home message is that severe menopausal symptoms may increase the risk of cardiovascular disease,” Matthew Nudy, MD, an assistant professor of medicine at the Heart and Vascular Institute at Penn State University, Hershey, said in an interview about his findings. “Physicians and patients should be aware of this association. Women with severe symptoms may be more likely to see their physician, and this would be an ideal time to have their cardiovascular risk assessed.”

Margaret Nachtigall, MD, a clinical associate professor of obstetrics and gynecology at New York University and at NYU Langone Health, noted that these findings lined up with other studies showing an increased risk of cardiovascular disease in patients who have more symptoms, especially hot flashes.

“Other recent studies showed that an increase in severity of hot flush is associated with worse blood vessel function, leading to heart disease,” Dr. Nachtigall, who was not involved with the study, said in an interview. “The next step that makes sense is to try to eliminate these symptoms and hope that, in turn, would lower cardiovascular disease and improve survival.”

The researchers compared menopausal symptoms with cardiovascular outcomes and all-cause mortality in an observational cohort of 80,278 postmenopausal women for a median 8.2 years of follow-up. None of the women, all enrolled in the Women’s Health Initiative, had known cardiovascular disease at baseline. They had an average age of 63 years and average body mass index (BMI) of 25.9 at baseline. Most participants were White (86.7%), with 7% being Black and 4.1% Hispanic. Cardiovascular disease was a composite outcome that included hospitalized myocardial infarction, definite silent myocardial infarction, coronary death, stroke, congestive heart failure, angina, peripheral vascular disease, carotid artery disease, and coronary revascularization.

The researchers used a four-item Likert scale (0-3) to assess the severity of 15 symptoms experienced within the past 4 weeks at baseline: “night sweats, hot flashes, waking up several times at night, joint pain or stiffness, headaches or migraines, vaginal or genital dryness, heart racing or skipping beats, breast tenderness, dizziness, tremors (shakes), feeling tired, forgetfulness, mood swings, [feeling] restless or fidgety, and difficulty concentrating.”

The associations were adjusted for the following covariates: race/ethnicity, blood pressure, education, smoking status, bilateral oophorectomy, menopausal hormone therapy use (never/past/current), sleep duration, statin use, history of high cholesterol, aspirin use, use of antihypertensives, treated diabetes, and family history of heart attack. Continuous variables included age, age at menopause, BMI, blood pressure, and physical activity levels. Because of the high number of multiple comparisons, the researchers also used a Bonferroni correction to reduce the risk of spurious statistical significance.

The researchers found some clustering of symptoms. Among women who had at least two moderate or severe menopausal symptoms, more than half frequently woke up at night, had joint pain, or felt tired, the researchers reported. Those symptoms were also the most commonly reported ones overall. Younger women, between ages 50 and 59, were more likely than older women (60-79 years old) to experience vasomotor symptoms and all cognitive affective symptoms except forgetfulness.

The researchers identified 10 symptoms whose severity was significantly associated with cardiovascular disease. Compared to having no symptoms at all, the following moderate or severe symptoms were associated with an increased risk of a cardiovascular event after adjustment for covariates and corrected for multiple comparisons: night sweats – a 19% increased risk (P = .03), waking up several times at night – 11% increased risk (P = .05), joint pain or stiffness – 27% increased risk (P < .001), heart racing or skipping beats – 55% increased risk (P < .001), dizziness – 34% increased risk (P < .001), feeling tired – 35% increased risk (P < .001), forgetfulness – 25% increased risk (P < .001), mood swings – 21% increased risk (P = .02), feeling restless or fidgety – 29% increased risk (P < .001), and difficulty concentrating – 31% increased risk (P < .001)

In addition, all-cause mortality was associated with these symptoms when they were moderate or severe: heart racing or skipping beats (32% increased risk of all-cause mortality; hazard ratio, 1.32; P =.006), dizziness (HR, 1.58; P < .001), tremors (HR, 1.44; P < .001), feeling tired (HR, 1.26; P < .001), forgetfulness (HR, 1.29; P = .01), mood swings (HR, 1.35; P = .02), feeling restless or fidgety (HR, 1.35; P < .001), and difficulty concentrating (HR, 1.47; P < .001).

The symptom with the greatest association with all-cause mortality was dizziness, which was associated with an increased risk of 58% when rated moderate or severe. Any dizziness at all was linked to a 12% increased risk of cardiovascular disease, compared with no dizziness. Machine learning with the LASSO method determined that the symptoms most predictive of cardiovascular disease were dizziness, heart racing, feeling tired, and joint pain. The symptoms most associated with all-cause mortality, based on the machine learning algorithm, were dizziness, tremors, and feeling tired.

Dr. Nudy said that their study did not look at mitigation strategies. “Women should discuss with their physician the best methods for cardiovascular risk reduction,” he said. He also cautioned that severe menopausal symptoms can also indicate other health conditions that may require investigation.

“It is certainly possible some symptoms may represent other medical conditions we were unable to control for and may not be directly related to menopause,” such as autoimmune diseases, endocrine abnormalities, or subclinical cardiovascular disease, he said. Additional limitations of the study included an older cohort and retrospective assessment of menopausal symptoms only at baseline. In addition, ”we did not assess the cardiovascular risk among women whose symptoms persisted versus resolved during the study period,” Dr. Nudy said.

Dr. Nachtigall said a key message is that people who are experiencing these symptoms should try to get treatment for them and attempt to alleviate them, hopefully reducing the risk of heart disease and death.

”Estrogen treatment is one excellent option for some individuals and should be considered in the appropriate person,” Dr. Nachtigall said. “If estrogen treatment is to be considered, it should be given closer to menopause, within the first 10 years after menopause and in younger individuals (under 59) at start.”

Dr. Nachtigall referred to the NAMS 2022 position statement concluding that, for healthy women within 10 years of menopause who have bothersome menopause symptoms, “the benefits of hormone therapy outweigh its risks, with fewer cardiovascular events in younger versus older women.”

”Menopause and having menopausal symptoms is an opportunity for clinicians and patients to have a conversation about appropriate individualized management options,” Dr. Nachtigall said.

Women may also be able to mitigate their cardiovascular risk with regular exercise, eating a healthy diet, not smoking, and getting adequate sleep, Dr. Nachtigall said. But these healthy behaviors may not adequately treat moderate or severe menopausal symptoms.

“Some health care providers have said that because menopause happens naturally, individuals should just accept the symptoms and try to wait it out and not get treatment, but this study, as well as others, makes it clear that it actually may be beneficial to treat the symptoms,” Dr. Nachtigall said.

The research used no external funding. Dr. Nudy and Dr. Nachtigall had no disclosures.

The relationship between estrogen levels and heart health makes it particularly important for clinicians to be aware of those patients who might be at risk for cardiovascular disease despite not having other traditional risk factors, according to a presentation Oct. 12 at the North American Menopause Society annual meeting in Atlanta.

”Endogenous estrogens are protective for cardiovascular disease in premenopausal women,” Chrisandra L. Shufelt, MD, chair of the division of general internal medicine and associate director of the Women’s Health Research Center at Mayo Clinic in Jacksonville, Fla., told attendees. Yet, “a substantial population of young women are dying prematurely from cardiovascular disease,” with rates of cardiovascular death increasing in women aged 35-44 even as rates have decreased in postmenopausal women and in men. One potential reason may be premature estrogen loss.

Dr. Shufelt reminded attendees of four major causes of premature estrogen loss: Natural premature menopause, surgical menopause, chemotherapy-induced menopause, and premature ovarian insufficiency. But she would go on to discuss a less widely recognized condition, functional hypothalamic amenorrhea, that also may be contributing to increased cardiovascular risk.

First, Dr. Shufelt reviewed the evidence supporting the relationship between estrogen and cardiovascular health, starting with the Framingham study’s findings that cardiovascular disease is approximately two to four times more common in postmenopausal women than in premenopausal women, depending on the age range.

“Menopause at an early age, particularly under the age of 40, matters,” Dr. Shufelt said. “So we should be discussing this with our patients.”

Surgical menopause makes a difference to cardiovascular health as well, she said. In women under age 35, for example, the risk of a nonfatal heart attack in those with a bilateral oophorectomy was 7.7 times greater than in women who retained both ovaries and their uterus, and 1.5 times greater in women who had a hysterectomy without bilateral oophorectomy.

In a 2019 study, surgical premature menopause was associated with an 87% increased risk of heart disease even after researchers accounted for age, cardiovascular risk factors, and some forms of hormone therapy. The increased risk from natural premature menopause, on the other hand, was lower – a 36% increased risk of heart disease – compared with those producing endogenous hormones. Although randomized controlled trials are unavailable and unlikely to be done, the Nurses’ Health Study and the Danish Nurses Cohort Study, both observational studies, found that heart disease risk was diminished in those taking hormone therapy after surgical premature menopause.

Recommendations for premature or early menopause, from a wide range of different medical societies including NAMS, are that women without contraindications be given estrogen-based hormone therapy until the average age of natural menopause. Though not included in the same guidance, research has also shown that estrogen after oophorectomy does not increase the risk of breast cancer in women with a BRCA1 mutation, Dr. Shufelt said. Hormone therapy for premature or early menopause should adequately replace the levels women have lost and that means younger menopausal women often need higher doses than what older women receive, such as 2 mg/day of oral estradiol rather than the standard doses of 0.5 or 1 mg/day.
 

Functional hypothalamic amenorrhea and cardiovascular risk

Dr. Shufelt then discussed functional hypothalamic amenorrhea (hypogonadotropic hypogonadism), a common type of secondary amenorrhea that affects at least 1.4 million U.S. women. Diagnosis includes lack of a period for at least 3 months in someone who previously menstruated plus lab values below 50 pg/mL for estradiol, below 10 mIU/L for follicle stimulating hormone, and below 10 mIU/L for luteinizing hormone. Causes of this reversible form of infertility can include stress, overexercising, undereating, or some combination of these, plus an underlying genetic predisposition.

“After ruling out polycystic ovary syndrome, prolactinoma, and thyroid dysfunction, clinicians need to consider the diagnosis of hypothalamic amenorrhea,” Dr. Shufelt said. This condition goes beyond low estrogen levels: Women have elevated cortisol, low thyroid levels, low leptin levels, and increased ghrelin.

”This is not going away,” Dr. Shufelt said, sharing data on stress levels among U.S. adults, particularly Gen Z and millennial adults, noting that the ongoing “national mental health crisis” may be contributing to functional hypothalamic amenorrhea.

A 2020 substudy from the Nurses’ Health Study II found an increased risk of premature death in those who didn’t have a period or always had irregular periods starting as early as 14-17 years old. The increased risk of premature death rose with age in those with irregular or absent cycles – a 37% higher risk in 18- to 22-year-olds and a 39% increased risk in 29- to 46-year-olds.

But clinicians aren’t adequately identifying the “phenotype of the hypothalamic women,” Dr. Shufelt said, despite research showing overlap between hypothalamic amenorrhea and a higher risk of cardiovascular disease. Hypothalamic amenorrhea is so understudied that the last original research on the topic was in 2008, Dr. Shufelt said in an interview. ”No research except mine has been done to evaluate heart health in these young women,” she said.

Dr. Shufelt described a study she led involving 30 women with functional hypothalamic amenorrhea, 29 women with normal menstrual cycles, and 30 women who were recently menopausal and not on hormone therapy. The women with hypothalamic amenorrhea had average stress levels but their depression scores were higher than those of the other two groups.

The results showed that women with hypothalamic amenorrhea had lower estradiol and leptin levels and higher testosterone levels compared with the control group, and they had higher cortisol levels than those of both groups. Despite having similar body mass indexes as the control and menopausal groups, women with hypothalamic amenorrhea had lower blood pressure than that of the other two groups, yet they had higher cholesterol levels than those of the control group. EndoPAT^© (Itamar Medical) testing showed that they had poor vascular function.

“In fact, one-third of the women [with hypothalamic amenorrhea] entered the trial with a diagnosis of what would be considered endothelial dysfunction,” Dr. Shufelt said. “Our results demonstrated significantly higher circulating levels of serum proinflammatory cytokines in the women with hypothalamic amenorrhea compared to eumenorrheic controls.”

Dr. Shufelt’s team then tested whether giving estradiol to the women with hypothalamic amenorrhea for 12 weeks would improve their vascular health, but they saw no significant differences between the women who received estrogen and those who received placebo.

“Endothelial function is partly mediated by estrogen, and it was expected that giving back estrogen would ‘fix’ the endothelium, but that is not what happened,” Nanette Santoro, MD, professor and chair of obstetrics and gynecology at the University of Colorado at Denver, Aurora, said in interview. “The mechanisms that maintain vascular function in women are not limited to hormones,” said Dr. Santoro, who was not involved in Dr. Shufelt’s study but attended her lecture. “We need to think beyond the simple model of estrogen-good, no-estrogen-bad.”

Dr. Santoro noted how easy it is to overlook the women who may have cardiovascular risk because of hypothalamic amenorrhea.

“Because many women with functional hypothalamic amenorrhea are super athletic and do not have the typical features of people with cardiometabolic disease – such as glucose intolerance, obesity, abnormal cholesterol or triglycerides, or high blood pressure – clinicians tend to think of them as healthy and to think that simply giving back hormones will fix the problems with bone density and vascular function, but that is not enough,” Dr. Santoro said. “The cognitive-behavioral therapy model for treatment of women with functional hypothalamic amenorrhea addresses the stress-related factors that drive the disorder, and this needs to be considered the standard of care for treatment.”

Stephanie S. Faubion, MD, professor of medicine and director of Mayo Clinic’s Center for Women’s Health in Jacksonville, Fla., who was not involved in Dr. Shufelt’s presentation, also emphasized the importance of recognizing functional hypothalamic amenorrhea.

“This is an underrecognized entity to begin with, and the fact that these women appear to be at increased risk for vascular dysfunction and potentially increased risk for cardiovascular disease down the road makes it even more important for clinicians to identify them and provide interventions early on,” Dr. Faubion said in an interview. “These women need to be identified and the etiology of the amenorrhea addressed, whether it relates to overexercising, being underweight, or experiencing significant stressors that have led to the loss of menstrual cycles.”

Dr. Shufelt’s research was funded by the National Institutes of Health. She had no disclosures. Dr. Santoro is a member of the scientific advisory board for Astellas, Menogenix, Amazon Ember, and Que Oncology, and she consults for Ansh Labs. Dr. Faubion had no disclosures.

Diagnosis includes lack of a period for at least 3 months in someone who previously menstruated plus lab values below 50 pg/mL for estradiol, below 10 mIU/L for follicle stimulating hormone, and below 10 mIU/L for luteinizing hormone. Causes of this reversible form of infertility can include stress, overexercising, undereating, or some combination of these, plus an underlying genetic predisposition.

“After ruling out polycystic ovary syndrome, prolactinoma, and thyroid dysfunction, clinicians need to consider the diagnosis of hypothalamic amenorrhea,” Dr. Shufelt said. This condition goes beyond low estrogen levels: Women have elevated cortisol, low thyroid levels, low leptin levels, and increased ghrelin.

”This is not going away,” Dr. Shufelt said, sharing data on stress levels among U.S. adults, particularly Gen Z and millennial adults, noting that the ongoing “national mental health crisis” may be contributing to functional hypothalamic amenorrhea.

A 2020 substudy from the Nurses’ Health Study II found an increased risk of premature death in those who didn’t have a period or always had irregular periods starting as early as 14-17 years old. The increased risk of premature death rose with age in those with irregular or absent cycles – a 37% higher risk in 18- to 22-year-olds and a 39% increased risk in 29- to 46-year-olds.

But clinicians aren’t adequately identifying the “phenotype of the hypothalamic women,” Dr. Shufelt said, despite research showing overlap between hypothalamic amenorrhea and a higher risk of cardiovascular disease. Hypothalamic amenorrhea is so understudied that the last original research on the topic was in 2008, Dr. Shufelt said in an interview. ”No research except mine has been done to evaluate heart health in these young women,” she said.

Dr. Shufelt described a study she led involving 30 women with functional hypothalamic amenorrhea, 29 women with normal menstrual cycles, and 30 women who were recently menopausal and not on hormone therapy. The women with hypothalamic amenorrhea had average stress levels but their depression scores were higher than those of the other two groups.

The results showed that women with hypothalamic amenorrhea had lower estradiol and leptin levels and higher testosterone levels compared with the control group, and they had higher cortisol levels than those of both groups. Despite having similar body mass indexes as the control and menopausal groups, women with hypothalamic amenorrhea had lower blood pressure than that of the other two groups, yet they had higher cholesterol levels than those of the control group. EndoPAT^© (Itamar Medical) testing showed that they had poor vascular function.

“In fact, one-third of the women [with hypothalamic amenorrhea] entered the trial with a diagnosis of what would be considered endothelial dysfunction,” Dr. Shufelt said. “Our results demonstrated significantly higher circulating levels of serum proinflammatory cytokines in the women with hypothalamic amenorrhea compared to eumenorrheic controls.”

Dr. Shufelt’s team then tested whether giving estradiol to the women with hypothalamic amenorrhea for 12 weeks would improve their vascular health, but they saw no significant differences between the women who received estrogen and those who received placebo.

“Endothelial function is partly mediated by estrogen, and it was expected that giving back estrogen would ‘fix’ the endothelium, but that is not what happened,” Nanette Santoro, MD, professor and chair of obstetrics and gynecology at the University of Colorado at Denver, Aurora, said in interview. “The mechanisms that maintain vascular function in women are not limited to hormones,” said Dr. Santoro, who was not involved in Dr. Shufelt’s study but attended her lecture. “We need to think beyond the simple model of estrogen-good, no-estrogen-bad.”

Dr. Santoro noted how easy it is to overlook the women who may have cardiovascular risk because of hypothalamic amenorrhea.

“Because many women with functional hypothalamic amenorrhea are super athletic and do not have the typical features of people with cardiometabolic disease – such as glucose intolerance, obesity, abnormal cholesterol or triglycerides, or high blood pressure – clinicians tend to think of them as healthy and to think that simply giving back hormones will fix the problems with bone density and vascular function, but that is not enough,” Dr. Santoro said. “The cognitive-behavioral therapy model for treatment of women with functional hypothalamic amenorrhea addresses the stress-related factors that drive the disorder, and this needs to be considered the standard of care for treatment.”

Stephanie S. Faubion, MD, professor of medicine and director of Mayo Clinic’s Center for Women’s Health in Jacksonville, Fla., who was not involved in Dr. Shufelt’s presentation, also emphasized the importance of recognizing functional hypothalamic amenorrhea.

“This is an underrecognized entity to begin with, and the fact that these women appear to be at increased risk for vascular dysfunction and potentially increased risk for cardiovascular disease down the road makes it even more important for clinicians to identify them and provide interventions early on,” Dr. Faubion said in an interview. “These women need to be identified and the etiology of the amenorrhea addressed, whether it relates to overexercising, being underweight, or experiencing significant stressors that have led to the loss of menstrual cycles.”

Dr. Shufelt’s research was funded by the National Institutes of Health. She had no disclosures. Dr. Santoro is a member of the scientific advisory board for Astellas, Menogenix, Amazon Ember, and Que Oncology, and she consults for Ansh Labs. Dr. Faubion had no disclosures.

The relationship between estrogen levels and heart health makes it particularly important for clinicians to be aware of those patients who might be at risk for cardiovascular disease despite not having other traditional risk factors, according to a presentation Oct. 12 at the North American Menopause Society annual meeting in Atlanta.

”Endogenous estrogens are protective for cardiovascular disease in premenopausal women,” Chrisandra L. Shufelt, MD, chair of the division of general internal medicine and associate director of the Women’s Health Research Center at Mayo Clinic in Jacksonville, Fla., told attendees. Yet, “a substantial population of young women are dying prematurely from cardiovascular disease,” with rates of cardiovascular death increasing in women aged 35-44 even as rates have decreased in postmenopausal women and in men. One potential reason may be premature estrogen loss.

Dr. Shufelt reminded attendees of four major causes of premature estrogen loss: Natural premature menopause, surgical menopause, chemotherapy-induced menopause, and premature ovarian insufficiency. But she would go on to discuss a less widely recognized condition, functional hypothalamic amenorrhea, that also may be contributing to increased cardiovascular risk.

First, Dr. Shufelt reviewed the evidence supporting the relationship between estrogen and cardiovascular health, starting with the Framingham study’s findings that cardiovascular disease is approximately two to four times more common in postmenopausal women than in premenopausal women, depending on the age range.

“Menopause at an early age, particularly under the age of 40, matters,” Dr. Shufelt said. “So we should be discussing this with our patients.”

Surgical menopause makes a difference to cardiovascular health as well, she said. In women under age 35, for example, the risk of a nonfatal heart attack in those with a bilateral oophorectomy was 7.7 times greater than in women who retained both ovaries and their uterus, and 1.5 times greater in women who had a hysterectomy without bilateral oophorectomy.

In a 2019 study, surgical premature menopause was associated with an 87% increased risk of heart disease even after researchers accounted for age, cardiovascular risk factors, and some forms of hormone therapy. The increased risk from natural premature menopause, on the other hand, was lower – a 36% increased risk of heart disease – compared with those producing endogenous hormones. Although randomized controlled trials are unavailable and unlikely to be done, the Nurses’ Health Study and the Danish Nurses Cohort Study, both observational studies, found that heart disease risk was diminished in those taking hormone therapy after surgical premature menopause.

Recommendations for premature or early menopause, from a wide range of different medical societies including NAMS, are that women without contraindications be given estrogen-based hormone therapy until the average age of natural menopause. Though not included in the same guidance, research has also shown that estrogen after oophorectomy does not increase the risk of breast cancer in women with a BRCA1 mutation, Dr. Shufelt said. Hormone therapy for premature or early menopause should adequately replace the levels women have lost and that means younger menopausal women often need higher doses than what older women receive, such as 2 mg/day of oral estradiol rather than the standard doses of 0.5 or 1 mg/day.

The drug fezolinetant, a selective neurokinin-3 receptor antagonist under investigation for treatment of menopausal vasomotor symptoms, showed acceptable long-term safety and tolerability during a 1-year phase 3 randomized controlled trial, according to data presented at the annual meeting of the North American Menopause Society. The study, called SKYLIGHT 4, examined fezolinetant treatment, especially in terms of endometrial health.

The findings mean that fezolinetant “may help bridge a gap in the management of vasomotor symptoms,” according to lead author Genevieve Neal-Perry, MD, PhD, chair of the department of obstetrics and gynecology at the University of North Carolina at Chapel Hill.

This study was an important step in fezolinetant’s path toward potential approval by the Food and Drug Administration for vasomotor symptoms.

”Moderate and severe vasomotor symptoms can adversely affect quality of life of those affected and result in sleep disruption as well as increased risk for heart disease and other high-risk medical problems,” Dr. Neal-Perry said. “Although menopausal hormone therapy significantly improves vasomotor symptoms, it may not be desired or it may not be safe for some women,” resulting in gaps in care and a need for targeted, nonhormonal therapies for hot flashes. A planned study will also assess the safety of the drug in patients with a diagnosis of hormone-sensitive cancer and disorders that increase the risk for blood clots.

”Fezolinetant has a low side effect profile, it is a nonhormonal option, and it is selective for the neurons that trigger and mediate hot flashes,” Dr. Neal-Perry said.

Hot flashes are caused by kisspeptin, neurokinin B, and dynorphin neurons located in the hypothalamus. Fezolinetant works by selectively blocking the neurokinin 3 receptor (NK3R), which regulates a person’s sense of temperature, Dr. Neal-Perry explained. Overactivation of NK3R, resulting from low estrogen levels, plays a role in the hot flashes and cold sweats women experience during menopause.

Drug development for hot flashes ”has been hampered by a lack of knowledge regarding the biological cause,” Dr. Neal-Perry said. “Now that we have a robust understanding of the basic biology of hot flashes, we can develop novel, highly effective, and targeted therapy.”

This safety study involved 1,830 women, ages 40-65, who were experiencing menopausal vasomotor symptoms and were randomly assigned to one of three arms for 52 weeks: 45 mg of fezolinetant, 30 mg of fezolinetant, or a placebo once daily.

The primary endpoints included the percentage of women with endometrial hyperplasia, the percentage of women with endometrial cancer, and the frequency and severity of treatment-emergent adverse events (TEAEs). To meet the primary safety endpoint, no more than 1% of participants could have hyperplasia or malignancy, with an upper confidence interval boundary not greater than 4%. Women who met prespecified criteria for their endometrial health to be assessed, underwent endometrial biopsies at baseline and at the end of the study. Three independent pathologists analyzed the tissue without knowledge of which study arm each sample came from. Among the 599 endometrial biopsy samples, 0.5% of the 203 participants taking 45 mg fezolinetant had hyperplasia while none of the women in the other two arms did. Among the 210 women taking 30 mg of fezolinetant, 0.5% had a malignancy; no malignancies occurred in the other two arms.

Overall adverse events were similar across all three arms, including rates of adverse events leading to discontinuation. The most common adverse events were headache and COVID-19. TEAEs related to the drug were 18.1% in the 45-mg arm, 15.4% in the 30-mg arm, and 17.4% in the placebo arm. Serious adverse events were similar across all three arms, and only 0.5% of participants in the 45-mg arm experienced drug-related serious adverse events, compared with none of the women in the 30-mg arm and 0.2% of women in the placebo group.

”The frequency of transaminase elevations was low, and these TEAEs were generally isolated, transient, and resolved on treatment or with discontinuation,” the authors reported.

The next steps for fezolinetant will be to assess its effect on mood and quality of life measures related to vasomotor symptoms, Dr. Neal-Perry said.

Samantha Dunham, MD, a NAMS-certified menopause practitioner and an associate professor of obstetrics and gynecology at New York University, suggested the drug’s safety in the study is encouraging.

”As a medication that treats menopausal symptoms, the study confirmed there are no issues with the endometrium, or lining of the uterus, not that one would expect issues given the mechanism of action,” Dr. Dunham, also codirector of NYU Langone’s Center for Midlife Health and Menopause, said in an interview. Dr. Dunham was not involved in the study.

”Earlier versions of medication in this class have caused liver enzyme elevation.” The trial of this medication showed that there were only transient elevations in liver enzymes, which resolved upon cessation of the medication. Dr. Dunham said. ”If the medicine proves to be safe over long periods of time in different populations, this will be a very significant medication for treating menopausal vasomotor symptoms.”

The research was funded by Astellas Pharma. Dr. Dunham had no disclosures. Dr. Neal-Perry is a scientific advisory board member for Astellas and Ferring Pharmaceuticals, and has received research funding from Merck and Overa.

Symptoms of menopause can significantly disrupt a woman’s ability to work, according to a cross-sectional study presented at the annual meeting of the North American Menopause Society.

The study, by researchers at the Mayo Clinic, found that roughly one in eight women said issues stemming from menopause caused them to miss multiple days of work; reduce hours on the job; and even quit, retire, or be laid off.

“We were shocked to see the significant impact of menopause symptoms in the workplace,” Ekta Kapoor, MD, an associate professor of medicine at the Mayo Clinic in Rochester, Minn. said in an interview. “The potential economic impact of untreated menopause symptoms at the workplace is mind-boggling.”

The findings represent an opportunity to improve the treatment of menopause symptoms in working women and “draw attention to the need for creation of workplace policies that include education of employers, managers, and supervisors in order to support midlife women during this universal life stage transition,” Dr. Kapoor added.

Laurie Jeffers, DNP, certified menopause practitioner and codirector of the Center for Midlife Health and Menopause within the department of obstetrics & gynecology at New York University Langone Health, said the findings agree with the results of previous studies from the Netherlands and elsewhere.

“We know that across different studies up to 80% of women during the menopause transition and early post menopause will have high symptom burden, with vasomotor symptoms being the most common,” Dr. Jeffers said. “Psychological symptoms were notably significant in this study, which is also not surprising given that there can be an exacerbation of anxiety or depression during the menopausal transition due to the variability of hormonal activity during this time.”
 

4,400 women surveyed

Dr. Kapoor and colleagues analyzed data from 4,440 currently employed women, ages 45-60, who were enrolled in the Mayo Clinic Registry of Midlife Women and completed an online questionnaire between March and June 2021 about their menopause symptoms and the symptoms’ effects on their work. The participants all receive their primary care at one of four Mayo Clinic sites in Rochester; Scottsdale, Ariz.; Jacksonville, Fla.; and northwest Wisconsin.

The researchers defined an adverse outcome from a menopausal symptom as one that directly caused women to miss a day from work in the past year or, within the past 6 months, to cut back on work hours, to experience a layoff or job termination, or to quit, retire or change jobs.

Most of the respondents were White (95%), married (77%), and had at least a college degree (59%), and their average age was 54. Their overall average Menopause Rating Scale (MRS) score – including somatic, psychological, and urogenital domains – was 23.1, which indicated a severe level of menopause symptoms.

More than one in eight women (13%) reported having at least one adverse outcome because of menopause symptoms, most commonly missing work (11%).

The women reported missing an average 3 days of work because of menopause symptoms. About half as many (6%) reported cutting back on hours at work in the past 6 months. A small percentage reported being laid off in the past 6 months (0.3%), or quitting, retiring, or changing jobs in the past 6 months (1%) because of menopause symptoms.

Menopause symptoms may well be contributing to the gender wage gap, Dr. Kapoor said, in the same way that other factors affect women’s overall earnings, such as taking time off for having or raising a family, being responsible for a large share of housework, and taking on more mentoring or teaching roles that aren’t as highly valued at work.

“Women going through the menopause transition, and those who are postmenopausal, are at important stages of their careers,” Dr. Kapoor said. “They are often seeking, or already in leadership positions. Any impediments at this important stage in their professional lives can prove to be very costly, resulting in missed opportunities for promotion and leadership roles.”

Unsurprisingly, the higher a woman’s MRS score, the more likely she was to report an adverse work outcome, regardless of the symptom. For example, women whose symptom severity ranked in the top 25% overall were 15.6 times more likely to have an adverse work experience than those with the lowest level of symptoms (P < .001). Psychological symptoms had the greatest effect on work. Women whose psychological symptoms ranked in the top 25% in terms of severity were 21 times more likely to have an adverse work effect, compared with those with the lowest level of severity, according to the researchers.

The results echo findings from a recent survey from Carrot Fertility of 1,000 women, ages 40-55, about the effects of menopause on their careers. In that survey, 79% of respondents described working during menopause as more challenging than other common life stages and life experiences, including starting a new job, starting a family or getting a promotion.

Yet 77% of women felt uncomfortable talking with executives about the problem, and 63% didn’t feel comfortable talking to human resources about the issue. More than half (58%) didn’t want to discuss it with their immediate supervisor. Only 8% said their employer has offered significant support for menopause.

“Menopause symptoms continue to be undertreated for a variety of reasons [and] impact multiple aspects of a woman’s life, including her performance in the workplace,” Dr. Kapoor said. “In addition to focusing our attention on adequate treatment of menopause symptoms, we need advocacy for creation of workplace policies that can help women navigate this important and universal stage of their lives.”

Those policies might include education about menopause to increase knowledge and awareness among employers and managers, Dr. Kapoor said. She also noted the need to improve communication with women in discussing appropriate support and work adjustments during menopause.

"There is also evidence that less than 20%-30% of women seek help for their symptoms,” Dr. Jeffers said. “There are a variety of evidence-based hormonal and nonhormonal options available to ease these symptoms, and knowledgeable clinical management of these symptoms can favorably impact this transition. This study is interesting in that the population of women surveyed presumably had access to high-quality health resources and yet still had a high symptom burden.”

Dr. Kapoor cautioned that the data collection occurred in the midst of the COVID-19 pandemic, “which may have heightened the adverse experiences of women at the workplace. On the other hand, many of these women may have been working from home, which may have made their menopause experience more favorable than it would have been had they been working in actual offices,” thereby again underrepresenting the problem.

Dr. Kapoor added that the study population may not be representative since they all received treatment at a tertiary health care center and were almost all White women.

“Perhaps the impact of menopause symptoms in the minority populations and the community is even greater,” Dr. Kapoor said. “Our data might be underrepresenting the extent of the problem.”

The research did not use external funding. Dr. Kapoor has received grant support from Mithra Pharmaceuticals and consulted for Astellas, Mithra Pharmaceuticals, Scynexis, and Womaness. Dr. Jeffers had no disclosures.

Symptoms of menopause can significantly disrupt a woman’s ability to work, according to a cross-sectional study presented at the annual meeting of the North American Menopause Society.

The study, by researchers at the Mayo Clinic, found that roughly one in eight women said issues stemming from menopause caused them to miss multiple days of work; reduce hours on the job; and even quit, retire, or be laid off.

“We were shocked to see the significant impact of menopause symptoms in the workplace,” Ekta Kapoor, MD, an associate professor of medicine at the Mayo Clinic in Rochester, Minn. said in an interview. “The potential economic impact of untreated menopause symptoms at the workplace is mind-boggling.”

The findings represent an opportunity to improve the treatment of menopause symptoms in working women and “draw attention to the need for creation of workplace policies that include education of employers, managers, and supervisors in order to support midlife women during this universal life stage transition,” Dr. Kapoor added.

Laurie Jeffers, DNP, certified menopause practitioner and codirector of the Center for Midlife Health and Menopause within the department of obstetrics & gynecology at New York University Langone Health, said the findings agree with the results of previous studies from the Netherlands and elsewhere.

“We know that across different studies up to 80% of women during the menopause transition and early post menopause will have high symptom burden, with vasomotor symptoms being the most common,” Dr. Jeffers said. “Psychological symptoms were notably significant in this study, which is also not surprising given that there can be an exacerbation of anxiety or depression during the menopausal transition due to the variability of hormonal activity during this time.”
 

4,400 women surveyed

Dr. Kapoor and colleagues analyzed data from 4,440 currently employed women, ages 45-60, who were enrolled in the Mayo Clinic Registry of Midlife Women and completed an online questionnaire between March and June 2021 about their menopause symptoms and the symptoms’ effects on their work. The participants all receive their primary care at one of four Mayo Clinic sites in Rochester; Scottsdale, Ariz.; Jacksonville, Fla.; and northwest Wisconsin.

The researchers defined an adverse outcome from a menopausal symptom as one that directly caused women to miss a day from work in the past year or, within the past 6 months, to cut back on work hours, to experience a layoff or job termination, or to quit, retire or change jobs.

Most of the respondents were White (95%), married (77%), and had at least a college degree (59%), and their average age was 54. Their overall average Menopause Rating Scale (MRS) score – including somatic, psychological, and urogenital domains – was 23.1, which indicated a severe level of menopause symptoms.

More than one in eight women (13%) reported having at least one adverse outcome because of menopause symptoms, most commonly missing work (11%).

The women reported missing an average 3 days of work because of menopause symptoms. About half as many (6%) reported cutting back on hours at work in the past 6 months. A small percentage reported being laid off in the past 6 months (0.3%), or quitting, retiring, or changing jobs in the past 6 months (1%) because of menopause symptoms.

Menopause symptoms may well be contributing to the gender wage gap, Dr. Kapoor said, in the same way that other factors affect women’s overall earnings, such as taking time off for having or raising a family, being responsible for a large share of housework, and taking on more mentoring or teaching roles that aren’t as highly valued at work.

“Women going through the menopause transition, and those who are postmenopausal, are at important stages of their careers,” Dr. Kapoor said. “They are often seeking, or already in leadership positions. Any impediments at this important stage in their professional lives can prove to be very costly, resulting in missed opportunities for promotion and leadership roles.”

Unsurprisingly, the higher a woman’s MRS score, the more likely she was to report an adverse work outcome, regardless of the symptom. For example, women whose symptom severity ranked in the top 25% overall were 15.6 times more likely to have an adverse work experience than those with the lowest level of symptoms (P < .001). Psychological symptoms had the greatest effect on work. Women whose psychological symptoms ranked in the top 25% in terms of severity were 21 times more likely to have an adverse work effect, compared with those with the lowest level of severity, according to the researchers.

The results echo findings from a recent survey from Carrot Fertility of 1,000 women, ages 40-55, about the effects of menopause on their careers. In that survey, 79% of respondents described working during menopause as more challenging than other common life stages and life experiences, including starting a new job, starting a family or getting a promotion.

Yet 77% of women felt uncomfortable talking with executives about the problem, and 63% didn’t feel comfortable talking to human resources about the issue. More than half (58%) didn’t want to discuss it with their immediate supervisor. Only 8% said their employer has offered significant support for menopause.

Despite a lack of evidence and high cost, laser therapy continues to attract many women seeking “vaginal rejuvenation” to help reverse the physical symptoms of menopause.

Recent reviews of the medical literature continue to show that laser treatment appears to be less effective than estrogen at improving vaginal dryness and pain during sex, according to Cheryl B. Iglesia, MD, a professor of ob.gyn. and urology at Georgetown University, Washington.

“Laser for GSM [genitourinary syndrome of menopause] is showing some promise, but patients need to be offered [Food and Drug Administration]–approved treatments prior to considering laser, and users need to know how to do speculum and pelvic exams and understand vulvovaginal anatomy and pathology,” Dr. Iglesia, who directs the section of female pelvic medicine and reconstructive surgery at MedStar Washington Hospital Center, said in an interview, adding that patients should avoid “vaginal rejuvenation” treatments offered at med-spas.

Dr. Iglesia reviewed how these lasers work and then discussed the controversy over their marketing and the evidence for their use at the annual meeting of the North American Menopause Society.

By 3 years after menopause, more than half of women experience atrophy in their vagina resulting from a lack of estrogen. Marked by a thinning of the epithelium, reduced blood supply, and loss of glycogen, vulvovaginal atrophy is to blame for GSM.

Vaginal laser therapy has been a popular option for women for the last decade, despite a lack of evidence supporting its use or approval from regulators.

The FDA has issued broad clearance for laser therapy for incision, ablation, vaporization, and coagulation of body soft tissues, such as dysplasia, vulvar or anal neoplasia, endometriosis, condylomas, and other disorders. However, the agency has not approved the use of laser therapy for vulvovaginal atrophy, GSM, vaginal dryness, or dyspareunia.
 

Evidence regarding vaginal laser therapy

According to Dr. Iglesia, the evidence for vaginal laser therapy is mixed and of generally low quality. A systematic review published in the Journal of Sexual Medicine (2022 Jan 29. doi: 10.1016/j.jsxm.2021.12.010) presented mostly low-quality evidence from 25 studies and found promising data for genitourinary symptoms but not enough to justify its use for genitourinary symptoms just yet. Dr. Iglesia discussed her own small, multisite study of 62 participants, which compared vaginal laser with vaginal estrogen and found no differences between the two for multiple outcomes. (The study would have been larger if not for interruption from an FDA warning for an Investigational Device Exemption.)

A JAMA study from Australia found no difference between laser therapy and sham laser therapy, but the most recent systematic review, from JAMA Network Open, found no significant difference between vaginal laser and vaginal estrogen for vaginal and sexual function symptoms. This review, however, covered only the six existing randomized controlled trials, including Dr. Iglesia’s, which were small and had a follow-up period of only 3-6 months.

“There have only been a few randomized controlled trials comparing laser to vaginal estrogen therapy, and most of those did not include a placebo or sham arm,” Monica Christmas, MD, director of the Center for Women’s Integrated Health at the University of Chicago Medicine, said in an interview. “This is extremely important, as most of the trials that did include a sham arm did not find that laser was better than the sham.” Dr. Christmas was not a part of the presentation but attended it at NAMS.

The bottom line, she said, is that “current evidence is not sufficient to make conclusions on long-term safety or sustainability, nor is there compelling evidence to make claims on equivalence to vaginal estrogen therapy.” Currently, committee opinions from a half-dozen medical societies, including NAMS, oppose using vaginal laser therapy until rigorous, robust trials on long-term safety and efficacy have been conducted. The International Continence Society and International Society for the Study of Vulvovaginal Disease issued a joint statement in 2018 that emphasized that histologic changes from lasers do not necessarily equate with changes in function. The statement noted the lack of evidence for laser treatment of incontinence and prolapse and stated that it should not be used for vulvodynia or lichen sclerosus.

A 2020 statement from NAMS found “insufficient placebo-controlled trials of energy-based therapies, including laser, to draw conclusions of efficacy or safety or to make treatment recommendations.” A slightly more optimistic statement from the American Urogynecologic Society concluded that energy-based devices have shown short-term efficacy for menopause-related vaginal atrophy and dyspareunia, including effects lasting up to 1 year from fractionated laser for treat dyspareunia, but also noted that studies up to that time were small and measure various outcomes.
 

Recommendations on vaginal laser therapy

Given this landscape of uneven and poor-quality evidence, Dr. Iglesia provided several “common sense” recommendations for energy-based therapies, starting with the need for any practitioner to have working knowledge of vulvovaginal anatomy. Contraindications for laser therapy include any malignancy – especially gynecologic – undiagnosed bleeding, active herpes or other infections, radiation, and vaginal mesh, particularly transvaginal mesh. The provider also must discuss the limited data on long-term function and treatment alternatives, including FDA-approved therapies like topical estrogen, dehydroepiandrosterone sulfate (DHEA-S), ospemifene, and moisturizers, Dr. Iglesia said.

Adverse events associated with laser therapy, such as scarring or burning, are rare but do occur, and cost remains an issue, Dr. Iglesia said.

“Vaginal estrogen therapy is well established as a safe and effective treatment option based on high quality evidence,” Dr. Christmas said. “This is not the case for laser therapy. Rare, but serious harms are reported with vaginal laser, including burns, scarring, dyspareunia, pain, and potential irreversible damage.”

Dr. Iglesia also cautioned that clinicians should take extra care with vulnerable populations, particularly cancer patients and others with contraindications for estrogen treatment.

For those in whom vaginal estrogen is contraindicated, Dr. Christmas recommended vaginal moisturizers, lubricants, dilators, and physical therapy for the pelvic floor.

“In patients who fail those nonhormonal approaches, short courses of vaginal estrogen therapy or DHEA-S suppository may be employed with approval from their oncologist,” Dr. Christmas said.

Dr. Iglesia finally reviewed the major research questions that remain with laser therapy:

• What are outcomes for laser versus sham studies?
• What are long-term outcomes (beyond 6 months)
• What pretreatment is necessary?
• Could laser be used as a drug delivery mechanism for estrogen, and could this provide a synergistic effect?
• What is the optimal number and interval for laser treatments?

Dr. Iglesia had no industry disclosures but received honoraria for consulting at UpToDate. Dr. Christmas is a consultant for Materna. The presentation did not rely on any external funding.

Dr. Iglesia finally reviewed the major research questions that remain with laser therapy:

• What are outcomes for laser versus sham studies?
• What are long-term outcomes (beyond 6 months)
• What pretreatment is necessary?
• Could laser be used as a drug delivery mechanism for estrogen, and could this provide a synergistic effect?
• What is the optimal number and interval for laser treatments?

Dr. Iglesia had no industry disclosures but received honoraria for consulting at UpToDate. Dr. Christmas is a consultant for Materna. The presentation did not rely on any external funding.
