PHILADELPHIA – About two in five perimenopausal or postmenopausal women have ever used cannabis in any form, but 10% have used it in the past month, according to cross-sectional survey results presented at the annual meeting of the Menopause Society (formerly The North American Menopause Society).

Though most women reported using cannabis for recreational reasons, 13% used it only for medical reasons, most often for chronic pain, anxiety, sleep, and stress.

“These findings highlight the importance of recognizing and discussing cannabis use in the health care setting, and the need for additional research to evaluate the potential harms and/or benefits of use in this vulnerable population,” Carolyn J. Gibson, PhD, MPH, a staff psychologist in women’s health at the San Francisco VA Health Care System and an assistant professor of psychiatry and behavioral sciences at the University of California, San Francisco, told attendees.

As cannabis has become more accessible, with its use legalized in 38 states and Washington, D.C., the proportion of U.S. adults using it has doubled over about a decade, from 6% in 2007 to 12% in 2019, Dr. Gibson said. Further, women aged 50 and older are among the fastest-growing groups of users of cannabis, and it’s being increasingly used – and marketed – for treating menopause-related and aging-related symptoms, including insomnia, anxiety, and chronic pain, she said.

“With these decisions to use cannabis, medically or for these other purposes, there’s this perception that it’s harmless,” Dr. Gibson said. Yet potential health risks associated with cannabis include the usual health effects associated with any kind of smoking as well as dependence in those who use it more frequently and/or develop a tolerance for it. She noted that average THC potency has increased over time, and acute risks for using cannabis with high levels of THC – at least 15% or at least 10 mg – can include anxiety/panic, confusion, disturbing/intrusive thoughts, psychosis, and effects on coordination and cognition. She also acknowledged, however, that most of the data available on risks come from studies of men and younger adults rather than older women.

Given the growing normalization of cannabis use, Dr. Gibson’s team sought to better understand prevalence of use as well as types of use and reasons for use in perimenopasual and postmenopausal women. They analyzed data from a cross-sectional survey of women and gender-diverse members, aged 45-64, of Ipsos KnowledgePanel, an online panel with more than 60,000 participating members in the United States.

All the respondents identified themselves as female at birth and had not used gender-affirming therapy or undergone gender-affirming surgery. The survey included questions on sociodemographics, menopause status, frequency of cannabis use, types of cannabis used, reasons for using cannabis, and use of cannabis in the previous 30 days. The 5,174 respondents were an average 55 years old and predominantly non-Hispanic white (63%), with 13% non-Hispanic Black and 16% Hispanic. Two-thirds of the women reported working full- or part-time (67%) and two-thirds were postmenopausal (68%), with 64% reporting experiencing menopause symptoms.

About two in five respondents (42%) had ever used cannabis in any form, most often smoking it (83%) or consuming edibles (51%). Among those who had ever used it, 30% reported having smoked it daily or nearly daily for at least a year at some point.

Ten percent of respondents had used cannabis in the past month, again primarily smoking (56%) or edibles (52%), though 39% said they used it in more than one form, including vaping, dabbing, or topical use. Nearly half (46%) of the respondents who smoked cannabis recently did not know the THC potency of what they consumed, and just over 20% of those consuming edibles didn’t know the THC potency of what they used. However, about a third of those taking edibles used cannabis with less than 10 mg of THC, and a little over a quarter used edibles with 10 mg of THC.

Within the 10% who had used cannabis in the past month, nearly a third (31%) of respondents – or around 3.1% of the total sample – reported smoking cannabis daily or almost daily, and 19% (or 1.9% of the overall sample) consumed cannabis edibles daily or almost daily.

Most of the respondents who used cannabis said it was for recreational use (62%), but a quarter (25%) reported using it for both recreational and medical reasons, and 13% used it only for medical reasons. The most common reason women used cannabis was to treat chronic pain (28%), followed by nearly as many women reporting cannabis use for anxiety (24%), sleep (22%), and stress (22%). Six percent of women used cannabis specifically for menopause-related sleep and mood problems.

Given the growing use of cannabis in this population and the dearth of data on its effects in older women, Dr. Gibson highlighted the need for research examining the potential benefits and harms of cannabis for menopausal women.
 

Not risk-free

Susan D. Reed, MD, MPH, MSCP, a professor emeritus of ob.gyn. at the University of Washington, Seattle, and president of the Menopause Society, found the study well-executed and was not surprised by how many respondents had ever used cannabis.

“What did surprise me was that nearly a third reported daily use for at least 1 year and that 38% were medical marijuana users, not just recreational,” Dr. Reed said in an interview. The proportions of women using cannabis for menopausal symptoms or using it daily are concerning, she added.

“These individuals are at risk for dependence and health risks related to marijuana use,” Dr. Reed said. “Providers should always ask patients about OTC products, herbals, supplements, cannabis use, and alternative management of menopausal symptoms to better understand patient preferences for menopausal symptom therapies, so that treatment plans can be discussed with individual patient preferences in mind. We need to start with where the patient is coming from.”

Data presented throughout the conference has shown how people are “disillusioned with the care they are receiving for menopause,” Dr. Reed added. “It is so difficult to distinguish truth from myths based on information gained through social media, family, and friends, and that often is where most people are getting their information.”

Physicians often have not received adequate training on how to provide people with accurate information about menopause and managing menopausal symptoms, so she advises patients and physicians to visit reliable sites such as the Menopause Society, the Swan Study, and My Menoplan.

The research was funded by the Tobacco-Related Disease Research Program and the Veterans Administration. Dr. Gibson has provided unpaid consultation to Astellas Pharmaceuticals. Dr. Reed has received research support from Bayer and receives royalties from UpToDate.

Assessing a key aspect of bone architecture, for which clinicians can now be reimbursed under Medicare, can significantly improve the ability to predict a patient’s risk for bone fracture.

Although bone mineral density (BMD) is traditionally used to identify patients with osteoporosis or low bone mass, some physicians have begun incorporating the trabecular bone score (TBS) into their exams.

At the Cleveland Clinic Center for Specialized Women’s Health, factoring in the TBS changed the diagnosis for 16% of 432 patients, according to Holly Thacker, MD, the center’s director.

“Importantly, 11% got worse diagnoses, and I use that in terms of prioritizing treatment,” Dr. Thacker said in an interview. The ability to determine how degraded the bone microarchitecture is through a software system “is a huge advance.”

Dr. Thacker described her center’s experience with the technology at the annual meeting of the Menopause Society (formerly The North American Menopause Society).

While BMD captures the amount of minerals like calcium in the skeleton, TBS assesses the underlying microarchitecture by looking at the distribution of shades of gray on dual-energy x-ray absorptiometry (DXA) scans.

Based on the TBS, patients’ bones are classified as normal, partially degraded, or degraded. Among the 432 patients who received a TBS analysis in 2022, 3% shifted from a normal diagnosis to osteopenia, 8% worsened from osteopenia to osteoporosis, 4% went from osteopenia to normal, and 1.6% downgraded from osteoporosis to osteopenia, Dr. Thacker reported.

The new test may also provide some reassurance for female patients who have thinner bones, which may raise alarms based on BMD. TBS, however, may show that the structure of the bone looks normal.

“When you know that the microarchitecture is normal, you’re a lot less concerned that they actually have a bone disease of osteoporosis,” Dr. Thacker said.

Conversely, unexpectedly degraded bone raises questions.

“That makes you go back and say [to the patient]: ‘Have you been on steroids? Were you malnourished? Is there some other metabolic problem? Have you had some calcium disorder?’ ” Dr. Thacker said.

Dr. Thacker leverages the TBS to help patients obtain effective therapy, typically an anabolic agent followed by antiresorptive medication.

“When I see a patient who not only has osteoporosis on bone density but has completely degraded bone architecture, it’s a lot easier for me to make the argument to the insurance company that this patient is at grave risk for a low trauma fracture and bad outcome without the best treatment,” Dr. Thacker said.
 

10-year-old tech, recently covered

The Food and Drug Administration approved TBS software in 2012, but Medicare only recently started paying for it.

Medimaps Group, a company that markets imaging software to calculate TBS, announced in 2022 that reimbursement from the Centers for Medicare & Medicaid Services was available, at $41.53 on the Physician Fee Schedule and $82.61 on the Hospital Outpatient Prospective Payment Schedule.

“Reimbursement through CMS is an important endorsement of the clinical value of TBS for clinicians and their patients,” Didier Hans, PhD, MBA, the CEO of Medimaps, said in a statement at the time. He noted that more than 600,000 TBS procedures were being performed in the United States each year.

Nevertheless, the initial investment in purchasing the software may be a barrier for health systems.

“We are the first and only site in our health system to offer TBS, as this is an extra expense and not uniformly reimbursed by insurers,” Dr. Thacker reported at the meeting.
 

Potential drawbacks

The TBS software used in Dr. Thacker’s study has been validated only in Asian and White patients between certain ages and weights, meaning the system is not designed to be used for other populations. Other researchers have highlighted a need for trabecular bone scoring to be validated more broadly. The authors of a recent analysis, however, suggest that TBS can be used the same way no matter a patient’s race.

TBS “is going to be most helpful in those with osteopenia who are right near the threshold for treatment,” said Marcella Donovan Walker, MD, MS, in a presentation on bone quality at the meeting.

Many studies have shown that TBS “provides additive information to bone density,” said Dr. Walker, a professor of medicine in the division of endocrinology at Columbia University, New York. For example, a large study of women in Manitoba found that, regardless of whether their bone density was normal, osteopenic, or osteoporotic, those with a low TBS had a much higher risk for fracture.
 

‘Opportunistic screening’ with CT?

TBS relies on the same DXA scans that are used to calculate bone mineral density, so obtaining the score does not add time or radiation to the scanning process, Dr. Thacker said.

But many patients who should receive DXA scans do not, which adds to the promise of “opportunistic screening” for osteoporosis, Dr. Walker said. With this approach, physicians would analyze a CT scan that a patient received for another purpose, such as to investigate abdominal pain or chest pain.

“In these images is information about the bone,” Dr. Walker said.

Researchers have used high-resolution peripheral quantitative CT to perform finite element analysis, where a computer program simulates compression of the bone to create a measure of bone stiffness and determine the load required for a break.

One study found that including those elements predicted fractures better than bone mineral density or the Fracture Risk Assessment Tool alone, Dr. Walker noted.

Other aspects of bone quality include how many cracks are in the bone, the amount of adipose in the marrow space, and the rate at which bone is broken down and rebuilt. But Dr. Walker suggested that the longstanding focus on bone mineral density in clinical practice makes sense.

“By far, bone mass is the most important bone quality,” Dr. Walker said.

“We are the first and only site in our health system to offer TBS, as this is an extra expense and not uniformly reimbursed by insurers,” Dr. Thacker reported at the meeting.
 

Potential drawbacks

The TBS software used in Dr. Thacker’s study has been validated only in Asian and White patients between certain ages and weights, meaning the system is not designed to be used for other populations. Other researchers have highlighted a need for trabecular bone scoring to be validated more broadly. The authors of a recent analysis, however, suggest that TBS can be used the same way no matter a patient’s race.

TBS “is going to be most helpful in those with osteopenia who are right near the threshold for treatment,” said Marcella Donovan Walker, MD, MS, in a presentation on bone quality at the meeting.

Many studies have shown that TBS “provides additive information to bone density,” said Dr. Walker, a professor of medicine in the division of endocrinology at Columbia University, New York. For example, a large study of women in Manitoba found that, regardless of whether their bone density was normal, osteopenic, or osteoporotic, those with a low TBS had a much higher risk for fracture.
 

‘Opportunistic screening’ with CT?

TBS relies on the same DXA scans that are used to calculate bone mineral density, so obtaining the score does not add time or radiation to the scanning process, Dr. Thacker said.

But many patients who should receive DXA scans do not, which adds to the promise of “opportunistic screening” for osteoporosis, Dr. Walker said. With this approach, physicians would analyze a CT scan that a patient received for another purpose, such as to investigate abdominal pain or chest pain.

“In these images is information about the bone,” Dr. Walker said.

Researchers have used high-resolution peripheral quantitative CT to perform finite element analysis, where a computer program simulates compression of the bone to create a measure of bone stiffness and determine the load required for a break.

One study found that including those elements predicted fractures better than bone mineral density or the Fracture Risk Assessment Tool alone, Dr. Walker noted.

Other aspects of bone quality include how many cracks are in the bone, the amount of adipose in the marrow space, and the rate at which bone is broken down and rebuilt. But Dr. Walker suggested that the longstanding focus on bone mineral density in clinical practice makes sense.

“By far, bone mass is the most important bone quality,” Dr. Walker said.

Dr. Thacker is the executive director of the nonprofit Speaking of Women’s Health. Dr. Walker reported receiving funding from the National Institute of Arthritis and Musculoskeletal and Skin Diseases and Amgen.

The newly approved respiratory syncytial virus vaccine administered during pregnancy substantially reduces the clinical and economic burden of lower respiratory tract disease caused by RSV, according to research presented at an annual scientific meeting on infectious diseases.

“With RSV maternal vaccination that is associated with clinical efficacy of 69% against severe RSV disease at 6 months, we estimated that up to 200,000 cases can be averted, and that is associated with almost $800 million in total,” presenting author Amy W. Law, PharmD, director of global value and evidence at Pfizer, pointed out during a news briefing.

“RSV is associated with a significant burden in the U.S. and this newly approved and recommended maternal RSV vaccine can have substantial impact in easing some of that burden,” Dr. Law explained.

This study is “particularly timely as we head into RSV peak season,” said briefing moderator Natasha Halasa, MD, MPH, professor of pediatrics, division of pediatric infectious diseases at Vanderbilt University, Nashville, Tenn.

The challenge, said Dr. Halasa, is that uptake of maternal vaccines and vaccines in general is “not optimal,” making increased awareness of this new maternal RSV vaccine important.
 

Strong efficacy data

Most children are infected with RSV at least once by the time they reach age 2 years. Very young children are at particular risk of severe complications, such as pneumonia or bronchitis.

As reported previously by this news organization, in the randomized, double-blind, placebo-controlled phase 3 study, Pfizer’s maternal RSV vaccine had an almost 82% efficacy against severe RSV infection in infants from birth through the first 90 days of life.

The vaccine also had a 69% efficacy against severe disease through the first 6 months of life. As part of the trial, a total of 7,400 women received a single dose of the vaccine in the late second or third trimester of their pregnancy. There were no signs of safety issues for the mothers or infants.

Based on the results, the U.S. Food and Drug Administration approved the vaccine, known as Abrysvo, in August, to be given between weeks 32 and 36 of pregnancy.
 

New modeling study

Dr. Law and colleagues modeled the potential public health impact – both clinical and economic – of the maternal RSV vaccine among the population of all pregnant women and their infants born during a 12-month period in the United States. The model focused on severe RSV disease in babies that required medical attention.

According to their model, without widespread use of the maternal RSV vaccine, 48,246 hospitalizations, 144,495 emergency department encounters, and 399,313 outpatient clinic visits related to RSV are projected to occur annually among the U.S. birth cohort of 3.7 million infants younger than 12 months.

With widespread use of the vaccine, annual hospitalizations resulting from infant RSV would fall by 51%, emergency department encounters would decline by 32%, and outpatient clinic visits by 32% – corresponding to a decrease in direct medical costs of about $692 million and indirect nonmedical costs of roughly $110 million.

Dr. Law highlighted two important caveats to the data. “The protections are based on the year-round administration of the vaccine to pregnant women at 32 to 36 weeks’ gestational age, and this is also assuming 100% uptake. Of course, in reality, that most likely is not the case,” she told the briefing.

Dr. Halasa noted that the peak age for severe RSV illness is 3 months and it’s tough to identify infants at highest risk for severe RSV.

Nearly 80% of infants with RSV who are hospitalized do not have an underlying medical condition, “so we don’t even know who those high-risk infants are. That’s why having this vaccine is so exciting,” she told the briefing.

Dr. Halasa said it’s also important to note that infants with severe RSV typically make not just one but multiple visits to the clinic or emergency department, leading to missed days of work for the parent, not to mention the “emotional burden of having your otherwise healthy newborn or young infant in the hospital.”

In addition to Pfizer’s maternal RSV vaccine, the FDA in July approved AstraZeneca’s monoclonal antibody nirsevimab (Beyfortus) for the prevention of RSV in neonates and infants entering their first RSV season, and in children up to 24 months who remain vulnerable to severe RSV disease through their second RSV season.

The study was funded by Pfizer. Dr. Law is employed by Pfizer. Dr. Halasa has received grant and research support from Merck.

A novel DNA test system that assesses a person’s genetic predisposition for certain cancers – the first of its kind granted marketing authorization by the Food and Drug Administration – may become a valuable new public health tool.

The Common Hereditary Cancers Panel (Invitae) was approved late September following FDA review under the De Novo process, a regulatory pathway for new types of low- to moderate-risk devices.

Jezperklauzen/ThinkStock

Validation of the prescription-only in vitro test was based on assessments of more than 9,000 clinical samples, which demonstrated accuracy of at least 99% for all tested variants in 47 genes known to be associated with an increased risk of developing certain cancers, including breast, ovarian, uterine, prostate, colorectal, gastric, pancreatic as well as melanoma.
 

How the test system works

Next-generation sequencing assesses germline human genomic DNA extracted from a single blood sample collected at the point of care, such as a doctor’s office, and is sent to a laboratory for analysis.

Specifically, the system aims to detect substitutions, small insertion and deletion alterations, and copy number variants in the panel of 47 targeted genes.

This technology “can provide an important public health tool that offers individuals more information about their health, including possible predisposition for certain cancers,” Jeff Shuren, MD, JD, director of the FDA’s Center for Devices and Radiological health, explained in an FDA press release announcing the marketing authorization.

Clinical interpretation is based on evidence from the published literature, prediction programs, public databases, and Invitae’s own variants database, the FDA statement explained.
 

What the test can do

Not only can the Common Hereditary Cancer Panel identify genetic variants that increase an individual’s risk of certain cancers, the panel can also help identify potential cancer-related hereditary variants in patients already diagnosed with cancer.

The most clinically significant genes the test system can detect include BRCA1 and BRCA2, which have known associations with hereditary breast and ovarian cancer syndrome; Lynch syndrome–associated genes including MLH1, MSH2, MSH6, PMS2, and EPCAM; CDH1, which is largely associated with hereditary diffuse gastric cancer and lobular breast cancer; and STK11, which is associated with Peutz-Jeghers syndrome.

“Patients should speak with a health care professional, such as a genetic counselor, to discuss any personal/family history of cancer, as such information can be helpful in interpreting test results,” the FDA advised.
 

What the test can’t do

The test is not intended to identify or evaluate all known genes tied to a person’s potential predisposition for cancer. The test is also not intended for cancer screening or prenatal testing. 

For these reasons, and because genetics are not the only factor associated with developing cancer, negative test results could lead to misunderstanding among some patients about their cancer risk.

“Results are intended to be interpreted within the context of additional laboratory results, family history, and clinical findings,” the company wrote in a statement.
 

Test safety

Risks associated with the test include the possibility of false positive and false negative results and the potential for people to misunderstand what the results mean about their risk for cancer.

A false sense of assurance after a false negative result might, for instance, lead patients to forgo recommended surveillance or clinical management, whereas false positive test results could lead to inappropriate decision-making and undesirable consequences.

“These risks are mitigated by the analytical performance validation, clinical validation, and appropriate labeling of this test,” the agency explained.

Along with the De Novo authorization, the FDA is establishing special controls to define requirements for these tests. For instance, accuracy must be 99% or higher for positive agreement and at least 99.9% for negative agreement with a validated, independent method.
 

Public health implications

The information gleaned from this tool can “help guide physicians to provide appropriate monitoring and potential therapy, based on discovered variants,” Dr. Shuren said.

The marketing authorization of Invitae’s test established a new regulatory category, which “means that subsequent devices of the same type with the same intended use may go through FDA’s 510(k) premarket process,” the FDA explained.

The Food and Drug Administration approval of zuranolone for postpartum depression in August 2023 has raised many important questions (and opinions) about its future use in clinical practice.

At the UNC-Chapel Hill Center for Women’s Mood Disorders, we treat women and pregnant people throughout hormonal transitions, including pregnancy and the postpartum, and have been part of development, research, and now delivery of both brexanolone and zuranolone. While we are excited about new tools in the arsenal for alleviating maternal mental health, we also want to be clear that our work is far from complete and continued efforts to care for pregnant people and their families are imperative.

What is zuranolone?

Zuranolone (brand name Zurzuvae) is an oral medication developed by Sage Therapeutics and Biogen. It is a positive allosteric modulator of the GABA_A receptor, the brain’s major inhibitory system. As a positive allosteric modulator, it increases the sensitivity of the GABA_A receptor to GABA.

Zuranolone is very similar to brexanolone, a synthetic form of allopregnanolone, a neurosteroid byproduct of progesterone (see below). However, zuranolone is not an oral form of brexanolone – it was slightly modified to ensure good oral stability and bioavailability. It is metabolized by the hepatic enzyme CYP3A4 and has a half-life of 16-23 hours. Zurzuvae is currently produced in capsule form.
 

What does zuranolone treat?

Zuranolone is the first FDA-approved oral drug for postpartum depression (PPD). It follows brexanolone, an intravenous drug, which was the first FDA-approved medication for PPD. Though these are the first medications with specific approval for PDD, many other treatment options are currently available including therapy, SSRIs, serotonin norepinephrine reuptake inhibitors (SNRIs), and other treatments used in major depression.

How does zuranolone work?

courtesy UNC-Chapel Hill

Zuranolone is a neuroactive steroid, which means that it is a steroid that goes into and acts on the brain. Zuranolone binds to different GABA receptor subunits from those bound by other positive modulators, such as benzodiazepines (for example, lorazepam). As a synthetic form of allopregnanolone, a metabolite of progesterone which rises dramatically in pregnancy then drops during labor and delivery, zuranolone was originally thought to mitigate the response to this drop in patients that are vulnerable to it during the postpartum. An alternative proposed mechanism is that the increased GABAergic, inhibitory signaling with zuranolone may act directly to decrease depression irrespective of the exact mechanism by which the depression occurred.

How was it studied?

Zuranolone was studied in women with severe postpartum depression and had to meet criteria for major depressive disorder (MDD) no earlier than the third trimester of pregnancy (about 28 weeks’ gestation) and no later than 4 weeks post partum. Patients were excluded from these studies if they had a history of bipolar disorder, psychotic disorders, attempted suicide, or if they were at risk for suicide.

The two phase 3 clinical trials that led to FDA approval are ROBIN and SKYLARK. These studies measured the efficacy and safety of zuranolone at 30 mg and 50 mg, respectively, and met their end points of rapid improvement in depressive and anxiety symptoms in postpartum depression.
 

When will we be able to start using it?

It is anticipated that zuranolone will become commercially available in early 2024.

Who can prescribe it?

courtesy UNC-Chapel Hill

Those with medical licenses. Most people will likely receive treatment from their obstetric, family medicine, or psychiatric clinicians.

How much will it cost?

The manufacturers have not released this information as of August 2023.

What sort of doses and duration is recommended?

The current FDA recommended dose is 50 mg for 14 days, taken once per evening with a fatty meal. The dose can be reduced to 40 mg if there are central nervous system (CNS) depressant effects, and to 30 mg if the patient has severe hepatic or moderate-severe renal impairment. There are currently no studies on longer courses of treatment.

What happens if the patient relapses after a 14-day trial?

While there is no clear guidance, an open-label trial (The SHORELINE Study) demonstrated that a repeated 14-day administration can restore clinical response.

What are the side effects?

courtesy UNC-Chapel Hill

Common side effects include drowsiness, dizziness, lower energy, diarrhea, and symptoms similar to the common cold. Zuranolone can act like a CNS depressant and can lead to sedation and somnolence.

Are there any boxed warnings?

Because of the CNS depressant effects, zuranolone was given a boxed warning that patients should not drive or operate heavy machinery within 12 hours of taking the medication as it may lead to impairment. Similar to other antidepressants, there is also a warning that zuranolone may increase risk for suicidal thoughts in patients under 24 years old.

Can it be used with other medications?

Yes. In the original trials, women were allowed to remain on medications treating their depressive symptoms (such as SSRIs and SNRIs). According to the FDA, zuranolone can be used alone or with other antidepressants.

Are there any medicines to avoid?

We recommend caution with other medications which may increase sedation, such as benzodiazepines.

Can it be used with birth control?

Yes. In fact, because the outcomes on a fetus are not yet studied, it is recommended that patients be on concurrent birth control during treatment and for a week after cessation. This does not mean that zuranolone is known to cause issues with fetal development, but rather that we do not know at this time.

Can it be used in pregnancy?

As above, the outcomes on fetal development are not known at this time, nor are the effects of zuranolone on labor and delivery. More research will need to be done to understand if there is risk with taking zuranolone during pregnancy. It should be noted that allopregnanolone levels ordinarily reach quite high levels during pregnancy.
 

Long-term side effects?

Long-term side effects are unknown. The study duration of ROBIN and SKYLARK was 45 days.

Breastfeeding?

Use in lactation has not yet been studied. Continued research is needed.

Can it be used in mood changes related to other reproductive changes or diagnoses like premenstrual dysphoric disorder and perimenopause?

The mechanism by which zuranolone is thought to work – that is, during changes in reproductive hormones – is implicated in other reproductive transitions such as premenstrual dysphoric disorder and perimenopause when reproductive hormones are fluctuating, though at lower levels than in pregnancy. Research will be required to assess efficacy and safety; however, the mechanistic reasons is worth pursuing. Additionally, zuranolone has not been studied in postpartum psychosis.

Can zuranolone be used to treat other affective conditions besides postpartum depression? Bipolar disorder?

Zuranolone is currently only approved for the treatment of postpartum depression. It has not received FDA approval for major depression outside of the perinatal period at this time. Whether it may be beneficial for patients with a depressive episode that is part of an underlying bipolar disorder or other psychiatric illness is not yet known.

Anxiety?

Along with depressive symptoms, women who received zuranolone in the clinical trials also had improvements in anxiety symptoms. These findings provide some hope that zuranolone may eventually be beneficial in patients with anxiety.

However, to date zuranolone has not been directly studied as a treatment for anxiety disorders (such as generalized anxiety disorder, panic disorder, etc.), so its efficacy for these illnesses is currently unknown.
 

Insomnia?

In a study of 153 postpartum women, randomized to placebo or zuranolone, scale questions for insomnia were improved in the group receiving zuranolone. This provides some hope that, if zuranolone is appropriate, concurrent polypharmacy with a sleep aid can be avoided. Additionally, future evaluation of use in insomnia outside of PPD may be warranted.

How is it different from brexanolone?

The two are slightly different molecules. Brexanolone is synthetically identical to allopregnanolone and zuranolone has been altered to be active and orally bioavailable.

Brexanolone is a 60-hour infusion that requires hospital admission at an approved health care site. Zuranolone is an oral at-home once-daily dosing treatment for 14 days. Zuranolone does not require enrollment in a risk evaluation and mitigation strategy for risk of excessive sedation and sudden loss of consciousness.
 

When would you consider zuranolone vs. brexanolone vs. other antidepressants?

Zuranolone and brexanolone are rapid-acting antidepressants with a response within 14 days or 60 hours, respectively. Antidepressants such as SSRIs/SNRIs are still available, well studied, and work, although take longer to reach clinical efficacy and are accompanied by potentially troubling side effects (for example, weight gain, sexual dysfunction).

Time to treatment effect should be considered when assessing severity of symptoms and functional impairment of the mother and the overall family unit. Brexanolone requires continuous monitoring which may be beneficial for women who are severely impaired and may benefit from frequent clinical monitoring. Brexanolone does not require a dose reduction with hepatic impairment, however, should be avoided in end-stage renal disease because of the potential accumulation of the solubilizing agent.
 

Where can I find more information?

Many states have maternal mental health consultation lines (examples include NCMATTERS here in North Carolina and MCPAP for Moms in Massachusetts) for clinicians (mental health, primary care, and obstetricians) that can be utilized for questions about prescribing. Postpartum Support International also has a clinician line for those without state services.

We plan to update this entry upon market release and access to new information.

FDA Approves First Oral Treatment for Postpartum Depression. 2023 Aug 4. https://www.fda.gov/news-events/press-announcements/fda-approves-first-oral-treatment-postpartum-depression

ZURZUVAE – HIGHLIGHTS OF PRESCRIBING INFORMATION. https://www.accessdata.fda.gov/drugsatfda_docs/label/2023/217369s000lbl.pdf

The Food and Drug Administration approval of zuranolone for postpartum depression in August 2023 has raised many important questions (and opinions) about its future use in clinical practice.

At the UNC-Chapel Hill Center for Women’s Mood Disorders, we treat women and pregnant people throughout hormonal transitions, including pregnancy and the postpartum, and have been part of development, research, and now delivery of both brexanolone and zuranolone. While we are excited about new tools in the arsenal for alleviating maternal mental health, we also want to be clear that our work is far from complete and continued efforts to care for pregnant people and their families are imperative.

What is zuranolone?

Zuranolone (brand name Zurzuvae) is an oral medication developed by Sage Therapeutics and Biogen. It is a positive allosteric modulator of the GABA_A receptor, the brain’s major inhibitory system. As a positive allosteric modulator, it increases the sensitivity of the GABA_A receptor to GABA.

Zuranolone is very similar to brexanolone, a synthetic form of allopregnanolone, a neurosteroid byproduct of progesterone (see below). However, zuranolone is not an oral form of brexanolone – it was slightly modified to ensure good oral stability and bioavailability. It is metabolized by the hepatic enzyme CYP3A4 and has a half-life of 16-23 hours. Zurzuvae is currently produced in capsule form.
 

What does zuranolone treat?

Zuranolone is the first FDA-approved oral drug for postpartum depression (PPD). It follows brexanolone, an intravenous drug, which was the first FDA-approved medication for PPD. Though these are the first medications with specific approval for PDD, many other treatment options are currently available including therapy, SSRIs, serotonin norepinephrine reuptake inhibitors (SNRIs), and other treatments used in major depression.

How does zuranolone work?

courtesy UNC-Chapel Hill

Zuranolone is a neuroactive steroid, which means that it is a steroid that goes into and acts on the brain. Zuranolone binds to different GABA receptor subunits from those bound by other positive modulators, such as benzodiazepines (for example, lorazepam). As a synthetic form of allopregnanolone, a metabolite of progesterone which rises dramatically in pregnancy then drops during labor and delivery, zuranolone was originally thought to mitigate the response to this drop in patients that are vulnerable to it during the postpartum. An alternative proposed mechanism is that the increased GABAergic, inhibitory signaling with zuranolone may act directly to decrease depression irrespective of the exact mechanism by which the depression occurred.

How was it studied?

Zuranolone was studied in women with severe postpartum depression and had to meet criteria for major depressive disorder (MDD) no earlier than the third trimester of pregnancy (about 28 weeks’ gestation) and no later than 4 weeks post partum. Patients were excluded from these studies if they had a history of bipolar disorder, psychotic disorders, attempted suicide, or if they were at risk for suicide.

The two phase 3 clinical trials that led to FDA approval are ROBIN and SKYLARK. These studies measured the efficacy and safety of zuranolone at 30 mg and 50 mg, respectively, and met their end points of rapid improvement in depressive and anxiety symptoms in postpartum depression.
 

When will we be able to start using it?

It is anticipated that zuranolone will become commercially available in early 2024.

Who can prescribe it?

courtesy UNC-Chapel Hill

Those with medical licenses. Most people will likely receive treatment from their obstetric, family medicine, or psychiatric clinicians.

How much will it cost?

The manufacturers have not released this information as of August 2023.

What sort of doses and duration is recommended?

The current FDA recommended dose is 50 mg for 14 days, taken once per evening with a fatty meal. The dose can be reduced to 40 mg if there are central nervous system (CNS) depressant effects, and to 30 mg if the patient has severe hepatic or moderate-severe renal impairment. There are currently no studies on longer courses of treatment.

What happens if the patient relapses after a 14-day trial?

While there is no clear guidance, an open-label trial (The SHORELINE Study) demonstrated that a repeated 14-day administration can restore clinical response.

What are the side effects?

courtesy UNC-Chapel Hill

Common side effects include drowsiness, dizziness, lower energy, diarrhea, and symptoms similar to the common cold. Zuranolone can act like a CNS depressant and can lead to sedation and somnolence.

Are there any boxed warnings?

Because of the CNS depressant effects, zuranolone was given a boxed warning that patients should not drive or operate heavy machinery within 12 hours of taking the medication as it may lead to impairment. Similar to other antidepressants, there is also a warning that zuranolone may increase risk for suicidal thoughts in patients under 24 years old.

Can it be used with other medications?

Yes. In the original trials, women were allowed to remain on medications treating their depressive symptoms (such as SSRIs and SNRIs). According to the FDA, zuranolone can be used alone or with other antidepressants.

Are there any medicines to avoid?

We recommend caution with other medications which may increase sedation, such as benzodiazepines.

Can it be used with birth control?

Yes. In fact, because the outcomes on a fetus are not yet studied, it is recommended that patients be on concurrent birth control during treatment and for a week after cessation. This does not mean that zuranolone is known to cause issues with fetal development, but rather that we do not know at this time.

Can it be used in pregnancy?

As above, the outcomes on fetal development are not known at this time, nor are the effects of zuranolone on labor and delivery. More research will need to be done to understand if there is risk with taking zuranolone during pregnancy. It should be noted that allopregnanolone levels ordinarily reach quite high levels during pregnancy.
 

Long-term side effects?

Long-term side effects are unknown. The study duration of ROBIN and SKYLARK was 45 days.

Breastfeeding?

Use in lactation has not yet been studied. Continued research is needed.

Can it be used in mood changes related to other reproductive changes or diagnoses like premenstrual dysphoric disorder and perimenopause?

The mechanism by which zuranolone is thought to work – that is, during changes in reproductive hormones – is implicated in other reproductive transitions such as premenstrual dysphoric disorder and perimenopause when reproductive hormones are fluctuating, though at lower levels than in pregnancy. Research will be required to assess efficacy and safety; however, the mechanistic reasons is worth pursuing. Additionally, zuranolone has not been studied in postpartum psychosis.

Can zuranolone be used to treat other affective conditions besides postpartum depression? Bipolar disorder?

Zuranolone is currently only approved for the treatment of postpartum depression. It has not received FDA approval for major depression outside of the perinatal period at this time.

ZURZUVAE – HIGHLIGHTS OF PRESCRIBING INFORMATION. https://www.accessdata.fda.gov/drugsatfda_docs/label/2023/217369s000lbl.pdf

TOPLINE:

Approximately one-third of women with rheumatic diseases develop anemia by the third trimester of pregnancy, and two-thirds are iron deficient, according to findings from a longitudinal cohort study.

METHODOLOGY:

• Researchers analyzed data from 368 pregnancies in women with rheumatic diseases during the period 2014-2022; nearly two-thirds (62%) had a connective tissue disease, 16% had rheumatoid arthritis or juvenile idiopathic arthritis, 14% had spondyloarthritis, 3% had vasculitis, and 7% had other diseases.
• Patients were aged 17-44 years, with a median age of 32 years at the time of birth.
• Researchers examined the frequency of anemia and iron deficiency and the impact of anemia on adverse maternal and child outcomes.

TAKEAWAY:

• The prevalence of iron deficiency was 28%, 51%, and 62% in the first, second, and third trimesters, respectively.
• The prevalence of anemia was 18%, 27%, and 33% in the first, second, and third trimesters, respectively.
• There was an increased risk for fetal complications such as malformation, infections, small for gestational age, neonatal lupus, preterm birth, and abortion or stillbirth in association with maternal connective tissue disease (odds ratio, 2.14) and also with low maternal hemoglobin levels and maternal iron deficiency (ORs, 0.52 and 0.86, respectively).
• Lower maternal hemoglobin levels were associated with an increased risk for maternal complications (OR, 1.47) such as flare with adaption of rheumatic medication and pregnancy-related adverse events (preeclampsia, gestational diabetes, bleeding complications, and thromboembolism), but patients with connective tissue disease had a lower risk for maternal complications (OR, 0.51); mean serum ferritin had no significant impact on maternal complications (OR, 1.02).

IN PRACTICE:

“Patients with rheumatic diseases suffer more often and already in early pregnancy from iron deficiency,” the researchers write. Therefore, early identification of anemia and iron deficiency in this population could inform prepregnancy counseling.

SOURCE:

The lead author on the study was Ann-Christin Pecher, MD, of University Hospital Tübingen, Germany. The study was published online in Joint Bone Spine.

LIMITATIONS:

The findings were limited by the use of a single dataset that might not be representative of all pregnant patients with rheumatic diseases. Other limitations included the lack of a standardized approach to iron supplementation.

DISCLOSURES:

The study was supported by a grant from the Medical Faculty of Tübingen Clinician-Scientist to the lead author. The researchers report no relevant financial relationships.

• Lower maternal hemoglobin levels were associated with an increased risk for maternal complications (OR, 1.47) such as flare with adaption of rheumatic medication and pregnancy-related adverse events (preeclampsia, gestational diabetes, bleeding complications, and thromboembolism), but patients with connective tissue disease had a lower risk for maternal complications (OR, 0.51); mean serum ferritin had no significant impact on maternal complications (OR, 1.02).

IN PRACTICE:

“Patients with rheumatic diseases suffer more often and already in early pregnancy from iron deficiency,” the researchers write. Therefore, early identification of anemia and iron deficiency in this population could inform prepregnancy counseling.

SOURCE:

The lead author on the study was Ann-Christin Pecher, MD, of University Hospital Tübingen, Germany. The study was published online in Joint Bone Spine.

LIMITATIONS:

The findings were limited by the use of a single dataset that might not be representative of all pregnant patients with rheumatic diseases. Other limitations included the lack of a standardized approach to iron supplementation.

DISCLOSURES:

The study was supported by a grant from the Medical Faculty of Tübingen Clinician-Scientist to the lead author. The researchers report no relevant financial relationships.

When I close my eyes and imagine what it is I do for a living, I see a computer screen.

I’m primarily a clinical researcher, so much of what I do is looking at statistical software, or, more recently, writing grant applications. But even when I think of my clinical duties, I see that computer screen.

The reason? The electronic health record (EHR) – the hot, beating heart of medical care in the modern era. Our most powerful tool and our greatest enemy.

The EHR records everything – not just the vital signs and lab values of our patients, not just our notes and billing codes. Everything. Every interaction we have is tracked and can be analyzed. The EHR is basically Sting in the song “Every Breath You Take.” Every click you make, it is watching you.

Researchers are leveraging that panopticon to give insight into something we don’t talk about frequently: the issue of racial bias in medicine. Is our true nature revealed by our interactions with the EHR?

We’re talking about this study in JAMA Network Open.

Researchers leveraged huge amounts of EHR data from two big academic medical centers, Vanderbilt University Medical Center and Northwestern University Medical Center. All told, there are data from nearly 250,000 hospitalizations here.

The researchers created a metric for EHR engagement. Basically, they summed the amount of clicks and other EHR interactions that occurred during the hospitalization, divided by the length of stay in days, to create a sort of average “engagement per day” metric. This number was categorized into four groups: low engagement, medium engagement, high engagement, and very high engagement.

College-aged women ranked health care providers, the Internet, and school resources as their top resources for seeking information about direct-to-consumer screening for sexually transmitted infections, based on surveys from 92 individuals.

University of North Texas Health Science Center

Direct-to-consumer (DTC) sexually transmitted infection (STI) screening methods involve the use of self-collected samples outside of a clinical setting, and may help reach women who avoid screening or lack access to clinical care, wrote Stacey B. Griner, PhD, of the University of North Texas Health Science Center, Fort Worth, and colleagues.

However, data on the methods used to promote DTC to the young female population are limited, and the goal of the current study was to identify preferred sources and communication channels for DTC STI information in this population, they said.

In a study published in Sexually Transmitted Diseases, the researchers reviewed data from 92 women aged 18-24 years at a single university who participated in an online survey. Of these, 24 also participated in in-depth interviews. The mean age of the participants was 20.0 years, and all reported being sexually active in the past year. Approximately two-thirds (68.5%) were White, 24% were Hispanic, 13% were Black or African American; 63.0% overall were heterosexual.

Participants received a description of DTC methods and were asked whether they were interested in receiving more information, and if so, what were their preferred sources for receiving the information. Potential sources included health care providers, friends, family members, partners, the Internet, college resources, classes, and other, and participants were asked to rank these choices in order of preference.

More than half of the participants identified health care providers as their preferred source of information (56.5%), followed by trusted websites (25%), and university-based resources or friends (6.5% for both).

Overall, participants who underwent STI screening in the past 12 months ranked college resources higher than those who had not undergone screening.

Race played a significant role in ranking partners and family members as resources. Compared with Black participants, White participants and those who were biracial/multiracial/another race ranked partners as a significantly more preferred source, but the differences between White and biracial/multiracial/another race were not significant. White participants and Black participants were similar in ranking family as a preferred information source, but White participants, compared with biracial/multiracial/other participants, ranked family as a significantly more preferred source.

Differences in rankings were similar across sexual orientations.

In-depth interviews were conducted on the college campus prior to the COVID-19 pandemic. The mean age of the interview participants was 19.5 years, and most were non-Hispanic White. Sexual orientation was varied, with 50% identifying as heterosexual and 50% identifying as a sexual minority.

In the interviews, health care providers were seen as influential for considering DTC methods, with gynecologists, other specialists, and more experienced physicians deemed the most trustworthy. Interviewees noted social media sites as a way to provide information and raise awareness of DTC methods, such as through the advertisements feature on Instagram. They also identified university orientation as a way to reach students and provide information about DTC options in the context of other health-related orientation topics such as sexual consent and alcohol use.

Many interviewees also mentioned friends as a resource for discussing sex, sexuality, and STI screening, and said they would be accepting of information, knowledge, and emotional support when learning about DTC from friends.

The findings were limited by several factors, including the cross-sectional design, use of data from a single campus setting, and the overrepresentation of White women, and more studies are needed to identify differences by region and campus type that might guide interventions, the researchers noted. The study also was limited by “the lack of specificity of what participants considered to be credible Internet information sources,” they said.

However, the results suggest that using health care providers, trusted websites, and established college resources as dissemination channels may help increase the awareness and use of DTC methods for STI screening in young women, they concluded.

The study was supported in part by the Doug Kirby Adolescent Sexual Health Research Grant from the Rural Center for AIDS/STD Prevention at Indiana University and by the University of South Florida College of Public Health. The researchers had no financial conflicts to disclose.

Screening for cancer is only half the battle: Patients often fail to complete recommended follow-up and additional testing after an abnormal result, leaving them at risk, according to authors of a new study published in the Journal of the American Medical Association.

Results from the clustered, randomized clinical trial indicate that systems-based interventions, such as automating reminders in electronic health records (EHRs), outreach in the form of phone calls or letters, and assistance with barriers to health care, such as housing insecurity, can increase the number of patients who complete appropriate diagnostic follow-up after an abnormal result.

Patients who received an EHR reminder, outreach call or letter, and additional calls to screen for and assist with nine barriers to health care – housing insecurity, food insecurity, paying for basic utilities, family caregiving, legal issues, transportation, financial compensation for treatment, education, and employment – completed follow-up within 120 days of study enrollment at a rate of 31.4%. The follow-up rate was 31% for those who received only an EHR reminder and outreach, 22.7% for those who received only an EHR reminder, and 22.9% for those who received usual care.

“The benefits of cancer screening won’t be fully realized without systems to ensure timely follow-up of abnormal results,” said Anna Tosteson, ScD, director of the Dartmouth Institute for Health Policy and Clinical Practice in Lebanon, N.H., a coauthor of the study.

Current payment incentives and quality-of-care indicators focus on getting people in for screening but should also address completion of screening – meaning timely and appropriate follow-up of results that could be indicative of cancer, Dr. Tosteson said.

“There’s a disconnect if you have screening rates that are high but once people have an abnormal result, which is potentially one step closer to a cancer diagnosis, there are no systems in place to help clinicians track them,” said study coauthor Jennifer Haas, MD, director of the Center for Primary Care Research at Massachusetts General Hospital in Boston.

In a 2016 study, researchers found that follow-up rates after abnormal cancer screenings varied widely. While 95.6% of patients with abnormal breast cancer screenings underwent timely follow-up testing, only 68.1% of patients with colorectal abnormalities and 44.8% of patients with cervical abnormalities did so.

Researchers for the new study used guideline recommendations and specialist input to create automated EHR algorithms that determined a follow-up period and diagnostic test.

They put the algorithm into practice with 11,980 patients who were part of 44 primary care practices within three health networks between August 2020 and December 2021. All patients had received abnormal test results for colorectal, breast, cervical, or lung cancer in varying risk categories.

All patients received usual care from their providers, which consisted of a “hodgepodge of whatever their clinic usually does,” Dr. Haas said. Without standards and systems in place for follow-up, the burden of testing and tracking patients with abnormal results typically falls on the primary care provider.

The researchers intervened only when patients were overdue for completion of follow-up. They then staggered the interventions sequentially.

All study participants received an automated, algorithm-triggered EHR reminder for follow-up in their patient portal along with routine health maintenance reminders. To view the reminder, patients had to log into their portal. Participants in the outreach and outreach and navigation groups also received a phone call, an EHR message, or a physical letter 2 weeks after receiving an EHR notification if they hadn’t completed follow-up. Research assistants performed the outreach after having been prompted by the algorithm.

After another 4 weeks, those in the EHR, outreach, and navigation group received a call from a patient navigator who helped them address nine barriers to health care, chiefly by providing them with referrals to free resources.

Among patients who received navigation, outcomes were not significantly better than among those who received EHR and outreach, indicating social determinants of health did not significantly affect the population studied or that the modest approach to navigation and the resources provided were insufficient, Dr. Haas said.

The complexity of an automated platform that encompasses many types of cancers, test results, and other data elements could prove difficult to apply in settings with less infrastructure, said Steven Atlas, MD, MPH, director of the Practice-Based Research and Quality Improvement Network in the division of general internal medicine at Mass General.

“I think there’s a role for the federal government to take on these initiatives,” Dr. Atlas said. Government intervention could help create “national IT systems to create standards for creating code for what an abnormal result is and how it should be followed,” he said.

While interventions improved patient follow-up, the overall rates were still low.

“What concerns me is that despite the various interventions implemented to encourage and support patients to return for follow-up testing, over 60% of patients still did not return for the recommended testing,” said Joann G. Elmore, MD, MPH, professor of medicine at the University of California, Los Angeles. Dr. Elmore was not involved with the study.

The research took place during the COVID-19 pandemic, which may have reduced follow-up, the study authors wrote. Still, given that previous research has shown that follow-up tends to be low, the rates highlight “the need to understand factors associated with not completing follow-up that go beyond reminder effort,” they wrote. These include a need for patient education about the meaning of test results and what follow-up procedures involve.

The study was supported by the National Cancer Institute and the American Cancer Society. The authors have disclosed no relevant financial relationships.
