Prominent NIH Neuroscientist Fired Over Alleged Research Misconduct
The misconduct involved “falsification and/or fabrication involving reuse and relabel of figure panels representing different experimental results in two publications,” the NIH said.
The agency said it will notify the two journals of its findings so that appropriate action can be taken.
The NIH reportedly launched its probe into potential research misconduct in May 2023 after it received allegations from the Health and Human Service (HHS) Office of Research Integrity (ORI) that month.
The investigation phase began in December 2023 and concluded on September 15, 2024. The institute subsequently notified HHS ORI of its findings.
Dr. Masliah joined the NIH in the summer of 2016 as director of the Division of Neuroscience at the NIA and an NIH intramural researcher investigating synaptic damage in neurodegenerative disorders, publishing “numerous” papers, the NIH said.
Given the findings of their investigation, the NIH said, Dr. Masliah is no longer serving as director of NIA’s Division of Neuroscience.
NIA deputy director Amy Kelley, MD, is now acting director of NIA’s neuroscience division.
Consistent with NIH policies and procedures, any allegations involving Dr. Masliah’s NIH-supported extramural research prior to joining NIH would be referred to HHS ORI, the NIH said.
The NIH announcement came on the same day that Science magazine published an investigative piece suggesting that Dr. Masliah may have fabricated or falsified images or other information in far more than the two studies NIH cited.
According to the article, “scores” of Dr. Masliah’s lab studies conducted at the NIA and the University of California San Diego are “riddled with apparently falsified Western blots — images used to show the presence of proteins — and micrographs of brain tissue. Numerous images seem to have been inappropriately reused within and across papers, sometimes published years apart in different journals, describing divergent experimental conditions.”
The article noted that a neuroscientist and forensic analysts who had previously worked with Science magazine produced a “300-page dossier revealing a steady stream of suspect images between 1997 and 2023 in 132 of his published research papers.”
They concluded that this “pattern of anomalous data raises a credible concern for research misconduct and calls into question a remarkably large body of scientific work,” the Science article stated.

Expert Calls for Research into GLP-1s for Mental Illness
MILAN — Recent research allaying concerns about suicidality linked to glucagon-like peptide 1 (GLP-1) receptor agonists, along with evidence of these agents’ potential psychiatric and cognitive benefits, has prompted the lead investigator of a major analysis to urge researchers to explore the potential of these drugs for mental illness.
“So far, we’ve been talking about the safety from a neuropsychiatric perspective in diabetes, but there is also the safety and benefit in people with mental disorders,” Riccardo De Giorgi, MD, PhD, from the Department of Psychiatry, University of Oxford in England, said in an interview.
The results of the meta-analysis were previously reported by this news organization and reviewed by Dr. De Giorgi at the 37th European College of Neuropsychopharmacology (ECNP) Congress. Dr. De Giorgi broached
Noting that GLP-1s are not approved for psychiatric disorders, Dr. De Giorgi said it can’t be assumed that the “metabolic or maybe even more general mechanisms that are being modified with these medications in diabetes or even in obesity are the same for people with psychiatric disorders. We’re talking about very different things. From a clinical perspective, you could do real harm,” he told this news organization.
Yet Dr. De Giorgi emphasized the importance of exploring the potential benefits of these medications in psychiatry.
“From a research perspective ... I am very worried about missing an opportunity here. This happened with rimonabant, a cannabis medication that was used for weight loss back in 2012 and was withdrawn quite dramatically in Europe immediately after licensing because it increased suicide risk. Since then, nobody has been touching the cannabinoid system, and that’s a shame because in psychiatry, we don’t have that much we can work on. So we don’t want to miss an opportunity with the GLP-1 system — that’s why we need to be cautious and look at safety first,” he said.
Signal of Efficacy?
Dr. De Giorgi’s research suggested several potential neurobiological effects of GLP-1 inhibition in diabetes research.
“There was a bit of a signal specifically for the big three dementias — vascular, Lewy Body, and frontotemporal — although there was not enough power,” he reported. “We also saw a reduced risk in nicotine misuse, especially amongst other substance use disorders ... and finally a more tentative association for reduced depression.”
He noted that GLP-1s for psychiatric illness likely have limitations and may not cure mental disorders but could help specific subsets of patients. Rather than aiming for large-scale studies, the focus should be on small, incremental studies to advance the research.
Asked by the session chair, John Cryan, PhD, from University College Cork in Ireland, and chair of the ECNP Scientific Committee whether improvement in patients’ mood could be attributed to weight loss, Dr. De Giorgi replied no.
“We now have quite a lot of studies that show that if there is an effect or association it is seen quite a bit earlier than any weight loss. Remember, weight loss takes quite a lot of time, and at quite high doses, but more provocatively, even if that’s the case, does it matter? We as psychiatrists do worry that we need to disentangle these things, but they don’t do that in cardiology, for example. If they see a benefit in mortality they don’t really care if it’s specifically an effect on heart failure or ischemic disease,” said Dr. De Giorgi.
Regardless of their neuropsychiatric potential, the cardiometabolic benefits of GLP-1 inhibitors are sorely needed in the psychiatric population, noted two experts in a recent JAMA Psychiatry viewpoint article.
Sri Mahavir Agarwal, MD, PhD, and Margaret Hahn, MD, PhD, from the University of Toronto and the Schizophrenia Division at the Centre for Addiction and Mental Health, in Toronto, Ontario, Canada, pointed out that “individuals with severe mental illness (SMI) have exceedingly high rates of metabolic comorbidity; three of four are overweight or obese, whereas the prevalence of type 2 diabetes (T2D) is several-fold higher than in the general population. Consequently, individuals with SMI die 15-20 years earlier from cardiovascular disease (CVD) than do those in the general population with CVD,” they noted.
“The arrival of semaglutide has infused significant enthusiasm in the field of mental health research. The proximal effects of weight and related CV comorbidities are significant in themselves. It is plausible that semaglutide could act through neurogenesis or secondary benefits of improving metabolic health on other important outcomes, such as cognitive health and quality of life, thereby filling an unmet need in the treatment of SMI,” Dr. Agarwal and Dr. Hahn added.
An Exciting Opportunity
Current research investigating GLP-1s in psychiatry and neurology is increasingly focused on neuroinflammation, said Dr. De Giorgi.
Research shows significant evidence that certain medications may help reduce dysfunctional inflammatory processes linked to various cognitive and psychiatric disorders, he added.
Many patients with established psychiatric conditions also have physical health issues, which contribute to increased mortality risk, said Dr. De Giorgi. It’s crucial to understand that, if these treatments improve mortality outcomes for psychiatric patients, the specific mechanisms involved are secondary to the results. Psychiatrists must be equipped to prescribe, manage, and initiate these therapies.
“While trials involving psychosis patients are ongoing, we are making progress and should seize this opportunity” said Dr. De Giorgi.
Dr. Cryan agreed: “I think we’ll get there. What these drugs have shown is that you can, through a single mechanism, have multitude effects related to brain-body interactions, and why not focus that on mood and anxiety and cognitive performance? It’s exciting no matter what. We now need to do longitudinal, cross-sectional, placebo-controlled trials in specific patient populations.”
This study received funding from the National Institute for Health and Care Research Oxford Health Biomedical Research Centre and Medical Research Council. Dr. De Giorgi’s coauthors reported receiving funding for other work from Novo Nordisk, Five Lives, Cognetivity Ltd., Cognex, P1vital, Lundbeck, Servier, UCB, Zogenix, Johnson & Johnson, and Syndesi. Dr. Cryan reported no relevant disclosures.

Healthy Lifestyle Mitigates Brain Aging in Diabetes
TOPLINE:
with brain age gaps of 2.29 and 0.50 years, respectively. This association is more pronounced in men and those with poor cardiometabolic health but may be mitigated by a healthy lifestyle.
METHODOLOGY:
- Diabetes is a known risk factor for cognitive impairment, dementia, and global brain atrophy but conflicting results have been reported for prediabetes, and it’s unknown whether a healthy lifestyle can counteract the negative impact of prediabetes.
- Researchers examined the cross-sectional and longitudinal relationship between hyperglycemia and brain aging, as well as the potential mitigating effect of a healthy lifestyle in 31,229 dementia-free adults (mean age, 54.8 years; 53% women) from the UK Biobank, including 13,518 participants with prediabetes and 1149 with diabetes.
- The glycemic status of the participants was determined by their medical history, medication use, and A1c levels.
- The brain age gap was calculated as a difference between chronologic age and brain age estimated from MRI data from six modalities vs several hundred brain MRI phenotypes that were modeled from a subset of healthy individuals.
- The role of sex, cardiometabolic risk factors, and a healthy lifestyle and their association with brain age was also explored, with a healthy lifestyle defined as never smoking, no or light or moderate alcohol consumption, and high physical activity.
TAKEAWAY:
- Prediabetes and diabetes were associated with a higher brain age gap than normoglycemia (beta-coefficient, 0.22 and 2.01; 95% CI, 0.10-0.34 and 1.70-2.32, respectively), and diabetes was more pronounced in men vs women and those with a higher vs lower burden of cardiometabolic risk factors.
- The brain ages of those with prediabetes and diabetes were 0.50 years and 2.29 years older on average than their respective chronologic ages.
- In an exploratory longitudinal analysis of the 2414 participants with two brain MRI scans, diabetes was linked to a 0.27-year annual increase in the brain age gap, and higher A1c, but not prediabetes, was associated with a significant increase in brain age gap.
- A healthy lifestyle attenuated the association between diabetes and a higher brain age gap (P = .003), reducing it by 1.68 years, also with a significant interaction between glycemic status and lifestyle.
IN PRACTICE:
“Our findings highlight diabetes and prediabetes as ideal targets for lifestyle-based interventions to promote brain health,” the authors wrote.
SOURCE:
This study, led by Abigail Dove, Aging Research Center, Department of Neurobiology, Care Sciences and Society, Karolinska Institutet, Stockholm, Sweden, was published online in Diabetes Care.
LIMITATIONS:
The generalizability of the findings was limited due to a healthy volunteer bias in the UK Biobank. A high proportion of missing data prevented the inclusion of diet in the healthy lifestyle construct. Reverse causality may be possible as an older brain may contribute to the development of prediabetes by making it more difficult to manage medical conditions and adhere to a healthy lifestyle. A1c levels were measured only at baseline, preventing the assessment of changes in glycemic control over time.
DISCLOSURES:
The authors reported receiving funding from the Swedish Research Council; Swedish Research Council for Health, Working Life and Welfare; Karolinska Institutet Board of Research; Riksbankens Jubileumsfond; Marianne and Marcus Wallenberg Foundation; Alzheimerfonden; and Demensfonden. They declared no relevant conflicts of interest.

Muscle Relaxants for Chronic Pain: Where Is the Greatest Evidence?
TOPLINE:
The long-term use of muscle relaxants may benefit patients with painful spasms or cramps and neck pain, according to a systematic review of clinical studies, but they do not appear to be beneficial for low back pain, fibromyalgia, or headaches and can have adverse effects such as sedation and dry mouth.
METHODOLOGY:
- Researchers conducted a systematic review to evaluate the effectiveness of long-term use (≥ 4 weeks) of muscle relaxants for chronic pain lasting ≥ 3 months.
- They identified 30 randomized clinical trials involving 1314 patients and 14 cohort studies involving 1168 patients, grouped according to the categories of low back pain, fibromyalgia, painful cramps or spasticity, headaches, and other syndromes.
- Baclofen, tizanidine, cyclobenzaprine, eperisone, quinine, carisoprodol, orphenadrine, chlormezanone, and methocarbamol were the muscle relaxants assessed in comparison with placebo, other treatments, or untreated individuals.
TAKEAWAY:
- The long-term use of muscle relaxants reduced pain intensity in those with painful spasms or cramps and neck pain. Baclofen, orphenadrine, carisoprodol, and methocarbamol improved cramp frequency, while the use of eperisone and chlormezanone improved neck pain and enhanced the quality of sleep, respectively, in those with neck osteoarthritis.
- While some studies suggested that muscle relaxants reduced pain intensity in those with back pain and fibromyalgia, between-group differences were not observed. The benefits seen with some medications diminished after their discontinuation.
- Despite tizanidine improving pain severity in headaches, 25% participants dropped out owing to adverse effects. Although certain muscle relaxants demonstrated pain relief, others did not.
- The most common adverse effects of muscle relaxants were somnolence and dry mouth. Other adverse events included vomiting, diarrhea, nausea, weakness, and constipation.
IN PRACTICE:
“For patients already prescribed long-term SMRs [skeletal muscle relaxants], interventions are needed to assist clinicians to engage in shared decision-making with patients about deprescribing SMRs. This may be particularly true for older patients for whom risks of adverse events may be greater,” the authors wrote. “Clinicians should be vigilant for adverse effects and consider deprescribing if pain-related goals are not met.”

The study, led by Benjamin J. Oldfield, MD, MHS, Yale School of Medicine, New Haven, Connecticut, was published online on September 19, 2024, in JAMA Network Open
LIMITATIONS:
This systematic review was limited to publications written in English, Spanish, and Italian language, potentially excluding studies from other regions. Variations in clinical sites, definitions of pain syndromes, medications, and durations of therapy prevented the possibility of conducting meta-analyses. Only quantitative studies were included, excluding valuable insights into patient experiences offered by qualitative studies.

Transgender Women and Prostate Cancer: It’s Complicated
The Veterans Health Administration (VHA) provides care for about 10,000 transgender women, and clinicians must understand their distinctive needs for prostate cancer screening, a urologist told cancer specialists during a presentation at the 2024 annual meeting of the Association of VA Hematology/Oncology in Atlanta.
Even if they’ve undergone gender reassignment surgery, “all transgender women still have a prostate, so therefore they remain at risk of prostate cancer and could still be considered for prostate cancer screening,” said Farnoosh Nik-Ahd, MD, a resident physician at the University of California San Francisco. However, “clinicians and patients may not be aware of prostate cancer risk, so that they may not think [of screening] transgender women.”
Nik-Ahd also noted another complication: The results of prostate screening tests may be misleading in this population.
Transgender women were born biologically male but now identify as female. These individuals may have undergone gender reassignment surgery to remove male genitalia, but the procedures do not remove the prostate. They also might be taking estrogen therapy. “Prostate cancer is a hormonally driven cancer, and the exact impact of gender-affirming hormones on prostate cancer risk and development is unknown,” Nik-Ahd said.
In a 2023 study in JAMA, Nik-Ahd and colleagues identified 155 cases of prostate cancer in transgender women within the VHA (about 14 cases per year) from 2000 to 2022. Of these patients, 116 had never used estrogen, while 17 had used it previously and 22 used it at diagnosis.
The median age of patients was 61 years, 88% identified as White, and the median prostate-specific antigen (PSA) was 6.8 ng/mL. “Given estimates of 10,000 transgender women in the US Department of Veterans Affairs, 33 cases per year would be expected. Instead, only about 14 per year were observed,” the researchers wrote. “Lower rates may stem from less PSA screening owing to barriers including lack of prostate cancer risk awareness or stigma, the suppressive effects of estrogen on prostate cancer development, or prostate cancers being missed in transgender women because of misinterpretation of ‘normal’ PSA levels among those receiving gender-affirming hormone therapies.”
In the presentation, Nik-Ahd said, “PSA density, which is a marker of prostate cancer aggressiveness, was highest in transgender women who were actively on estrogen.”
She noted, “the existing thyrotropin reference ranges, which is what we use to interpret PSA values, are all based on data from cisgender men.” The ranges would be expected to be far lower in transgender women who are taking estrogen, potentially throwing off screening tests, she said, and “ultimately missing clinically significant prostate cancer.”
In the larger picture, there are no specific guidelines about PSA screening in transgender women, she said.
A recent study published in JAMA by Nik-Ahd and colleagues examined PSA levels in 210 transgender women (mean age 60 years) treated within the VHA from 2000 to 2023. All were aged 40 to 80 years, had received estrogen for at least 6 months (mean duration 4.7 years), and didn’t have prostate cancer diagnoses.
“Median (IQR) PSA was 0.02 (0-0.2) ng/mL and the 95th percentile value was 0.6 ng/mL,” the report found. “PSAs were undetectable in 36% of patients (23% and 49% of PSAs in patients without and with orchiectomy, respectively).”
The researchers write that “the historic cut point of 4 ng/mL, often used as a threshold for further evaluation, is likely far too high a threshold for this population.”
Nik-Ahd noted, “clinicians should interpret PSA values in transgender women on estrogen with extreme caution. In this population, normal might actually not be normal, and a value that is considered normal might be very abnormal for somebody who is on estrogen. If you're unsure of whether a PSA value is appropriate for a transgender woman on estrogen, refer that patient to a urologist so they can undergo further evaluation.”

Cancer Risk: Are Pesticides the New Smoking?
Pesticides have transformed modern agriculture by boosting production yields and helping alleviate food insecurity amid rapid global population growth. However, from a public health perspective, exposure to pesticides has been linked to numerous harmful effects, including neurologic disorders like Parkinson’s disease, weakened immune function, and an increased risk for cancer.
A comprehensive assessment of how pesticide use affects cancer risk across a broader population has yet to be conducted.
A recent population-level study aimed to address this gap by evaluating cancer risks in the US population using a model that accounts for pesticide use and adjusts for various factors. The goal was to identify regional disparities in exposure and contribute to the development of public health policies that protect populations from potential harm.
Calculating Cancer Risk
Researchers developed a model using several data sources to estimate the additional cancer risk from agricultural pesticide use. Key data included:
- Pesticide use data from the US Geological Survey in 2019, which covered 69 agricultural pesticides across 3143 counties
- Cancer incidence rates per 100,000 people, which were collected between 2015 and 2019 by the National Institutes of Health and the Centers for Disease Control and Prevention; these data covered various cancers, including bladder, colorectal, leukemia, lung, non-Hodgkin lymphoma, and pancreatic cancers
- Covariates, including smoking prevalence, the Social Vulnerability Index, agricultural land use, and total US population in 2019
Pesticide use profile patterns were developed using latent class analysis, a statistical method used to identify homogeneous subgroups within a heterogeneous population. A generalized linear model then estimated how these pesticide use patterns and the covariates affected cancer incidence.
The model highlighted regions with the highest and lowest “additional” cancer risks linked to pesticide exposure, calculating the estimated increase in cancer cases per year that resulted from variations in agricultural pesticide use.
Midwest Most Affected
While this model doesn’t establish causality or assess individual risk, it reveals regional trends in the association between pesticide use patterns and cancer incidence from a population-based perspective.
The Midwest, known for its high corn production, emerged as the region most affected by pesticide use. Compared with regions with the lowest risk, the Midwest faced an additional 154,541 cancer cases annually across all types. For colorectal and pancreatic cancers, the yearly increases were 20,927 and 3835 cases, respectively. Similar trends were observed for leukemia and non-Hodgkin lymphoma.
Pesticides vs Smoking
The researchers also estimated the additional cancer risk related to smoking, using the same model. They found that pesticides contributed to a higher risk for cancer than smoking in several cases.
The most significant difference was observed with non-Hodgkin lymphoma, where pesticides were linked to 154.1% more cases than smoking. For all cancers combined, as well as bladder cancer and leukemia, the increases were moderate: 18.7%, 19.3%, and 21.0%, respectively.
This result highlights the importance of considering pesticide exposure alongside smoking when studying cancer risks.
Expanding Scope of Research
Some limitations of this study should be noted. Certain counties lacked complete data, and there was heterogeneity in the size and population of the counties studied. The research also did not account for seasonal and migrant workers, who are likely to be heavily exposed. In addition, the data used in the study were not independently validated, and they could not be used to assess individual risk.
The effect of pesticides on human health is a vast and critical field of research, often focusing on a limited range of pesticides or specific cancers. This study stands out by taking a broader, more holistic approach, aiming to highlight regional inequalities and identify less-studied pesticides that could be future research priorities.
Given the significant public health impact, the authors encouraged the authorities to share these findings with the most vulnerable communities to raise awareness.

Does Tailored Acupuncture Relieve Chronic Neck Pain?
TOPLINE:
Patients with chronic neck pain who received acupuncture experienced an alleviation of their symptoms, but not at clinically meaningful levels, compared with those who received sham treatment.
METHODOLOGY:
- A 24-week randomized trial was conducted at four clinical centers in China over a 2-year period starting in 2018.
- A total of 659 patients with chronic neck pain were randomly assigned to one of the four groups: Higher sensitive acupoints (mean age, 38.63 years; 70.41% women; n = 169), lower sensitive acupoints (mean age, 40.21 years; 74.4% women; n = 168), sham acupuncture (mean age, 40.16 years; 75.29% women; n = 170), and a waiting list (mean age, 38.63 years; 69.89% women; n = 176).
- Participants in the acupuncture groups had 10 sessions over 4 weeks and were followed up for 20 weeks. Those in the waiting list group received no treatment.
- The primary outcome was the change in neck pain at 4 weeks, measured on a 0-100 scale. A change of 10 points was considered clinically significant.
- The secondary outcomes were neck pain and movement, quality of life, and use of pain medication over 24 weeks.
TAKEAWAY:
- Acupuncture targeted at higher sensitive points led to a pain score reduction of 12.16 (95% CI, −14.45 to −9.87), while lower sensitive points reduced it by 10.19 (95% CI, −12.43 to −7.95).
- Sham acupuncture reduced the score by 6.11 (95% CI, −8.31 to −3.91), and no treatment reduced it by 2.24 (95% CI, −4.10 to −0.38).
- The higher and lower sensitive acupoint groups showed no clinically significant net differences in pain reduction and secondary outcomes compared with the sham and waiting list groups.
- Differences in reductions in pain between groups all decreased by week 24.
IN PRACTICE:

LIMITATIONS:
Blinding was not done in the waiting list group. Individuals in the higher and lower sensitive acupoint groups experienced a specific sensation after needle manipulation, which could have influenced the analysis. Additionally, the participants were middle-aged adults with moderate pain, which limited the generalizability to older individuals or those with severe pain.

Genitourinary Symptoms in Men: Canaries in the Coal Mine for Underlying Chronic Disease
At age 57, a senior scientific researcher in Santa Barbara, California, complained of chronic erectile dysfunction (ED) in what had been a sexually active marriage. “I just couldn’t get an erection, let alone sustain one. Apart from that, I maybe felt a bit tired but generally okay,” he said. Though seemingly well otherwise, 18 months later he was dead of a hereditary right-sided colon cancer.
While not all cases of ED are associated with a dire outcome, the genitourinary signals of ED and lower urinary tract symptoms (LUTS), especially nocturia, serve as sentinel indicators of the presence of, or risk factors for, serious chronic conditions. These commonly include cardiovascular disease (CVD), diabetes, and metabolic syndrome and are associated with obesity, depression, and obstructive sleep apnea.
Sometimes these serious conditions may stay under the radar until men seek help for ED or LUTS.
“We know that among men who had a heart attack, 50% had some degree of ED within 3 years of their cardiac event,” Sam Tafari, MBBS, of the Endocrine and Metabolic Unit at Royal Adelaide Hospital in Adelaide, South Australia, said in an interview.
That’s the bad news. The good news is that these two problems may specifically incentivize men to seek timely care for serious conditions they might otherwise not get, according to Dr. Tafari. And primary care doctors are ideally positioned to get men early multifaceted care. He recently coauthored a call to action on this issue in a review appearing in the Journal of Men’s Health.
In Dr. Tafari’s experience, most patients seeking urological care are unaware of the multiple conditions linked to ED and LUTS. “Many consider these to be due to issues like low testosterone, which actually make up a very small proportion of cases of ED,” he said. Aging, obesity, inactivity, smoking, alcohol abuse, and prescription and street drugs can also contribute to the development of ED.
In most affected men, ED is of vascular etiology, with endothelial dysfunction of the inner lining of blood vessels and smooth muscle the common denominator.
This dysfunction causes inadequate blood supply to both the coronary and the penile arteries, so ED and CVD are considered different manifestations of the same systemic disorder. Because the tumescence-controlling cavernosal vessels of the penis are considerably smaller, the same level of arteriopathy causes a more severe reduction in blood in the erectile tissue. As a result, ED often precedes CVD and presents an early opportunity to screen men for CVD.
As to the mechanisms behind LUTS, Peter N. Tsambarlis, MD, a urologist at Northwestern Medicine in Chicago, subscribes to the inflammation theory. “Suboptimal health issues such as high [blood] pressure, blood lipids, and blood glucose lead to chronic widespread inflammation, which makes the bladder less flexible as a storage vessel,” he explained. “It’s not able to stretch adequately overnight to hold the urine until morning.”
Ask Early, Ask Often
Jeffrey P. Weiss, MD, PhD, chair of the Department of Urology at SUNY Downstate Health Sciences University in Brooklyn, New York, has done research that uncovered a relationship between structural cardiac disease and nocturia. “So if you had to ask a patient a single question that would point to a global health issue, it would be ‘Do you have frequent nighttime urination,’ ” he said.
It’s never too soon to ask men about these symptoms, said Dr. Tsambarlis. The best time to raise issues of ED and LUTS is when a man enters primary care — regardless of age or absence of symptoms. “That way you have a baseline and can watch for changes and do early intervention as needed. Men don’t usually want to bring up sexual dysfunction or urinary health, but asking doesn’t need to dominate the visit,” he said.
Dr. Tafari recommends that primary care physicians adopt a targeted approach using ED and nocturia as entry points for engaging men in their healthcare. While acknowledging that primary care physicians have an ever-growing checklist of questions to ask patients and hardly need one more thing to screen for, he suggests asking two quick, and easy “before you go” genitourinary queries:
- Are you having trouble with erections or having sex?
- Are you getting up at night to pass urine more than once?
“The men really appreciate being asked,” he said. “But what worries me is all the men we don’t see who have these symptoms but don’t know they’re important, and no one is asking about them.”
Gideon Richards, MD, a urologist at the Northwell Health Physician Partners Smith Institute for Urology at Garden City, and director of Men’s Health, Central Region, for Northwell Health in New Hyde Park, both in New York, said erectile problems should not wait for specialty care. By the time men with ED are referred to urology, they may already have failed treatment with first-line phosphodiesterase 5 inhibitor therapy, he said. “A significant proportion will have arteriogenic erectile dysfunction, a measurable decrease in the amount of blood flow into the erectile bodies.”
Addressing the Issue
Addressing genitourinary-signaled issues has the double benefit of easing ED and LUTS and improving men’s health and longevity and may help narrow the worldwide gender gap in life expectancy. As a recent global analysis found, there’s a 5-year longevity disparity favoring women over men. Biology aside, men do not access healthcare as often as women, who consult their general practitioners regularly throughout their lifespan for multiple reasons, including reproductive care, and more screening programs are aimed at women.
Added Dr. Tsambarlis, “Men should know that losing weight and switching to a healthy lifestyle can improve sexual function about half as much as phosphodiesterase 5 inhibitors such as sildenafil [Viagra] or tadalafil [Cialis].”
“Many, however, would prefer just to take drugs rather than change their lifestyle and lose weight. There are certainly effective options available, but these are not uniformly effective,” said Dr. Weiss.
Dr. Tafari’s group is designing a short, simple, culturally acceptable screening tool for use in primary care practice and will monitor its impact on physician prescribing habits and overall men’s health outcomes.
Dr. Tafari received funding from the Hospital Research Foundation and Freemasons Centre for Male Health and Wellbeing in Adelaide, South Australia. Dr. Tafari, Dr. Tsambarlis, Dr. Weiss, and Dr. Richards had no relevant conflicts of interest to declare.

GLP-1 RA Therapy for Alcohol Use Disorder?
This transcript has been edited for clarity.
Akshay B. Jain, MD: Today we are very excited to have Dr. Leggio join us all the way from the National Institutes of Health (NIH). He is an addiction physician scientist in the intramural research program at NIH. Welcome, Dr. Leggio. Thanks for joining us.
Lorenzo Leggio, MD, PhD: Thank you so much.
Dr. Jain: We’ll get right into this. Your session was, in my mind, extremely informative. The session looked at glucagon-like peptide 1 receptor agonist (GLP-1 RA) therapy and its potential effects on mitigating alcohol misuse syndrome, so, reduction of alcohol addiction potentially.
We’ve seen in some previous clinical trials, including many from your group, that alcohol use is known to be reduced — the overall risk of incidence, as well as recurrence of alcohol use — in individuals who are on GLP-1 RA therapy.
Can you share more insights about the data already out there?
Dr. Leggio: At the preclinical level, we have a very robust line of studies, experiments, and publications looking at the effect of GLP-1 RAs, starting from exenatide up to, more recently, semaglutide. They show that these GLP-1 RAs do reduce alcohol drinking. They used different animal models of excessive alcohol drinking, using different species — for example, mice, rats, nonhuman primates — models that reflect the excessive alcohol drinking behavior that we see in patients, like physical alcohol dependence or binge-like alcohol drinking, and other behaviors in animal models that reflect the human condition.
In addition to that, we recently have seen an increase in human evidence that GLP-1 RAs may reduce alcohol drinking. For example, there is some anecdotal evidence and some analyses using social media showing that people on GLP-1 RAs report drinking less alcohol.
There are also some pharmacoepidemiology studies which are very intriguing and quite promising. In this case, people have been looking at electronic medical records; they have used the pharmacoepidemiology approaches to match patients on GLP-1 RAs because of diabetes or obesity, and have compared and matched to patients on different drugs as the controls.
A study was recently published Nature Communications by a group in Cleveland in collaboration with Dr. Nora Volkow from the National Institute on Drug Abuse. This study shows the association between being on a GLP-1 RA and the lower incidence of alcohol use disorder and lower drinking.
There is also some promise from prospective randomized clinical trials. In particular, there was one clinical trial from Denmark, a well-known and -conducted clinical trial where they looked at exenatide, and they didn’t see an effect of exenatide compared with placebo in the main analysis. But in a subanalysis, they did see that exenatide reduced alcohol drinking, but only in patients with alcohol use disorder and obesity.
This suggests that these medications may work for some patients and not for other patients. That’s fine, because just like in any other field in medicine, including diabetes, obesity, hypertension, Parkinson’s, and depression, not all medications work for everybody. If these medications will work for alcohol addiction, we do not expect that they will work for everybody.
One ongoing question in the field is to try to identify the phenotypes or the subgroup of people who may be more responsive to these medications.
Dr. Jain: This is such a fascinating field, and all these studies are coming out. In your review of all the literature so far, do you think this is dose dependent? Also, we see that, for instance, with certain individuals, when they take GLP-1 RA therapy, they might have a lot of gastrointestinal (GI) side effects. Recent studies have shown that the rate of these GI side effects does not necessarily correlate with the amount of weight loss. In the alcohol addiction field, do you think that the GI side effects, things like nausea, could also have a potential role in mitigating the alcohol addiction?
Dr. Leggio: This is a great question. They may play a role; they may contribute, too, but we don’t think that they are the driving mechanism of why people drink less, for at least a couple of reasons.
One is that, similar to the obesity field, the data we have so far don’t necessarily show a relationship between the GI side effects and the reduction in drinking. Plus, the reduction in drinking is likely to happen later when many GI side effects are gone or attenuated.
The second reason is from the neuroscience field. We are starting to better understand the mechanism at the brain level as to how these medications work. We don’t see that the nausea or, more generally, not feeling well — malaise, etc. — are driving mechanisms for how these medications work.
Again, it’s not to discount completely that the GI side effects may play a role, but I would say that, if anything, they may be more contributing to. And if they do, that will not be unique to this class of medication. For example, we have three medications approved by the US Food and Drug Administration (FDA) for alcohol use disorder.
One challenge we have in the addiction field is that many people don’t know that these medications exist — many primary care providers don’t know — and they are completely underutilized. Everybody here who is listening to us knows that roughly 85% of people with diabetes receive a medication for diabetes. For alcohol use disorder, the number is 2%. These are medications approved by the FDA.
One of them is naltrexone, which does give GI symptoms — in particular, nausea and vomiting. The other medication is acamprosate, which does give diarrhea.
You have medications approved for alcohol disorder where you do have some GI symptoms, but they are not the mechanism either for how these medications help people to curb craving and reduce alcohol drinking.
Dr. Jain: What about the dose-dependent action? Do you think that GLP-1 RAs, at a lower dose, may not have an effect on alcohol use disorder vs at a higher dose, or is everyone a little different?
Dr. Leggio: That’s a wonderful question. The short answer is, we don’t know, to be honest. Now, in some of the animal studies — my team has been in collaboration with other scientists in the NIH intramural research program, and also with scientists in academia, for example, at Scripps, UCLA — we see a dose response where the higher the dose, the higher the effect of the drug. In this case, semaglutide reduced binge drinking in a rat model of a physical alcohol dependence.
That said, I would be very cautious about claiming, based on the rodent data, that humans will have a dose response. It’s an open question. We really don’t know. Some of the pharmacoepidemiology data suggested that even lower doses — for example, using semaglutide for diabetes without going up to the obesity dose — may be just as effective as a higher dose in reducing the incidence of alcohol use disorder.
It’s important also to keep in mind that the pharmacoepidemiology data are always an association. Reduction in alcohol disorder is associated with the prescription GLP-1 RA, but they don’t really replace the more gold-standard, double-blind, placebo-controlled randomized clinical trial. Nonetheless, with the pharmacoepidemiology data, I think there is an argument to at least hypothesize that people may respond well, even to lower doses.
This also may be important from a safety standpoint.
Basically, we need to wait for results in the next years to come from randomized clinical trials to better unfold the question about doses. For example, just anecdotally, I will tell you that in the clinical trial we are conducting right now at the NIH Intramural Research Program, for which I’m the principal investigator (PI), we are going up to 2.4 mg — the highest dose of semaglutide.
We are collaborating with Kyle Simmons, PhD, from Oklahoma State University. Our two studies are not like a two-site clinical trial, but they are harmonized. In Dr. Simmons’ clinical trial, they’re going up to 1.0 mg. We are excited about this team approach because the trials are slightly different, but they’re harmonized to the point that, once the studies are done, we’ll be able to combine and compare data to better answer the question about dosing, and many other questions.
Dr. Jain: From a clinical perspective, we see that many people who are battling alcohol use disorder may not have obesity. They might actually be on the leaner side, and hence, we may not want to use a high dose of GLP-1 RA therapy. It’ll be very exciting to see when these results come out.
This brings me to the next question. I think everyone would love to know why this happens. Why is GLP-1 RA having this effect on alcohol use disorder? I know that your group has done many animal studies, as you pointed out, and one of the postulated theories was the effect on the GABA neurotransmission pathway.
Can you tell us more about what you feel is the underlying mechanism of action here?
Dr. Leggio: I will start by saying that we don’t fully know. There are many open questions. If I can sidetrack for one second: We come up with the idea that, first of all, alcohol use disorder and substance use disorder are addictive behaviors, addictive disorders. We define addiction as a brain disease.
Granted that addiction is a brain disease, it doesn’t mean that addiction works just in the brain in isolation. As we all know, the brain works in concert with the rest of the body. One specific approach my team has been taking is working on the analogy and the similarities between obesity and addiction to try to understand how the body-brain connection, such as the gut-brain-neuroendocrine pathway, may play a role in patients with addiction.
With that in mind, a large amount of work in my lab in the past 20 years — since I’ve been a PI — has been focused on studying this neuroendocrine pathways related to the gut-brain axis. For example, we have done work on insulin and leptin, primarily; we had done work on ghrelin, and since 2015 on the GLP-1 RAs.
With that in mind, the framework we are working on, which is also substantiated by many studies done by our team and other teams in the neuroscience field, kind of supports the idea that, similar to what we see in obesity, these medications may work by affecting what we call reward processing, or the seeking for addictive drugs, such as alcohol, and also the drugs such as the stimulants, opioids, nicotine, and so on.
The idea is that the mechanism is driven by the ability of the medication — semaglutide and all the GLP-1 RAs — to reduce the rewarding properties of alcohol and drugs. To maybe make the example more pragmatic, what does that mean? It means, for example, that a patient who typically has 10 drinks per day in the afternoon and night, while they are on the medication they may feel the lack of need to drink up to 10 to feel the same reward.
They may be able to stop after two or three drinks, which means a significant harm reduction and a beneficial outcome. This also brings us to another mechanism, which may be related to society. We don’t fully understand how much the society mechanism, including society mechanism related to GI motility, may also play a role.
With that said, we don’t think that the effect of the GLP-1 RAs is merely due to alcohol being a calorie-based nutrient because, in fact, we see alcohol as an addictive drug, not as a nutrient. Also, the GLP-1 RAs, at least in animal models, seem to work on other addictive drugs that don’t have calories, such as nicotine, and possibly with cannabis, opioids, and stimulants.
Then on the molecular level, our team recently showed, in collaboration with Dr. Marisa Roberto from Scripps in La Jolla, California, that semaglutide may in fact change the GABA transmission at the level of some brain regions, such as the amygdala and the prefrontal cortex. These are brain regions that are well-established hubs that play a role in the mechanism underlying addiction.
There are also some very exciting recent data showing how these medications may work not just on GABA or just on dopamine, which is the canonical way we conceive of reward processing, but by working on both by modulating GABA transmission — for example, at the ventral tegmental area and dopamine transmission at the nucleus accumbens.
Bottom line, if I summarize all of this, is that the mechanism is not fully understood, but there is definitely a contribution of this medication to effect and reward processing, possibly by altering the balance between GABA and dopamine. There are still some unknown questions, such as, are these mechanisms all brain driven or are they signaling from the periphery to the brain, or maybe both?
Also, as we all know, there are many differences across all these GLP-1 analogs in brain penetrance. Whether the drug needs to go to the brain to have an effect on alcohol drinking, cocaine seeking, or smoking is really an open question.
Dr. Jain: This is so thought-provoking. I guess the more we uncover, the more mesmerized we get with all the potential crosstalk. There is a large amount of overlap in the brain with each of these different things and how it all interplays with each other.
Speaking of interplay, I’m thinking about how many people prone to having alcohol use disorder can potentially develop complications, one of these being chronic pancreatitis. This is a well-known complication that can occur in people having alcohol addiction. Along that same line, we know that previous history of pancreatitis is considered a use-with-caution, or we don’t want to use GLP-1 RA therapy in people who have had pancreatitis.
Now it becomes this quagmire where people may have chronic pancreatitis, but we may want to consider GLP-1 RA therapy for management of alcohol use disorder. What are your thoughts about this, and the safety, potentially, in using it in these patients?
Dr. Leggio: This is another wonderful question. That’s definitely a top priority in our mind, to address these kinds of questions. For example, our RCT does have, as core primary outcomes, not only the efficacy defined as a reduction in alcohol drinking, but also safety.
The reason is exactly what you just explained. There are many unanswered questions, including whether giving a GLP-1 RA and alcohol together may have synergistic effects and increase the likelihood of having pancreatitis.
The good news is that, so far, based on the published literature, including the RCT done with exenatide in Denmark and published in 2022 and also the ongoing clinical trials — including my own clinical trial, but of course we are blind — pancreatitis has not been coming out as an adverse event.
However, it’s also true that it often happens in clinical medication development. Of course, we screen and select our population well. For example, we do exclude people who have a history of pancreatitis. We exclude people with high lipase or with any of the clinical symptomatology that makes us concerned about these people having pancreatitis.
As often happens when you move a medication from clinical trials to clinical practice, we still need to understand whether this medication works in patients. I’m just speculating, but even if the clinical trials do not raise red flags in terms of increased risk for some side effects such as pancreatitis, I think it will be very important for practitioners to keep a close eye on the death risk regardless.
It’s very interesting that it’s similar to alcohol liver disease. With pancreatitis, not every single patient with alcohol addiction has pancreatitis. We don’t really fully understand why some people develop pancreatitis and some people do not. The point being that there are many patients with alcohol addiction who don’t have pancreatitis and may benefit from these medications if they work. Again, we have to prove that in patients.
On the other side, as we all know, pancreatitis is a potentially life-threatening condition for those people who either have it or are at risk for it. I think we have to be very careful before we consider giving them a GLP-1 RA.
One could argue that alcohol is the leading cause of mortality and morbidity in the world. For example, right now, alcohol is the leading cause of liver disease. It’s the main reason for liver transplantation in our country. Alcohol is affecting thousands of people in terms of death and emergency room visits.
You could argue that the downside is not treating these people and they die because of alcohol addiction. A GLP-1 RA is not going to be for everybody. I will remind everybody that (1) we do have FDA-approved medications for alcohol addiction; and (2) there are also other medications not approved by the FDA, but with a proven efficacy in some clinical trials — for example, topiramate and gabapentin — and they’ve been endorsed by the American Psychiatric Association.
There is also some evidence for another medication, baclofen, which has been endorsed by the American College of Gastroenterology for patients with alcohol addiction and liver disease.
The point I’m making is that it’s not that either we use the GLP-1 RAs or we have no other tools. We have other tools. I think we have to personalize the treatment based on the patient’s profile from a safety standpoint and from a phenotypic standpoint.
Dr. Jain: I love that thought. I think individualization is the key here.
We know that people with diabetes have a higher risk for pancreatitis by virtue of having diabetes. People with obesity also have a higher risk for pancreatitis by virtue of having obesity. These are the two conditions where we are using a large amount of GLP-1 RA therapy. Again, the idea is looking at the person in front of us and then deciding, based on their past medical history and their current risk, whether or not a medication is a right fit for them.
I think more individualization here will come as we start using these medications that might be having potential effects on different organ systems. You mentioned a little bit about the liver, so a thought came in my mind. We know that people with diabetes who have alcohol use disorder are at a higher risk for potential hypoglycemia. If they have events when they have increased consumption of alcohol, there can be more hypoglycemia.
We now could potentially be using semaglutide or other GLP-1 RA therapy for management of alcohol use disorder. In your own experience in the studies that you’ve done or the literature that’s out there, has that been associated with an even higher risk for hypoglycemia?
Dr. Leggio: It’s a wonderful question. I’m not aware of any formal and published report of that association. That said, your thinking from a physiopathologist standpoint makes total sense. I could not agree more. The fact that nothing has been published, at least to my knowledge, doesn’t mean that the death risk doesn’t exist. In fact, I agree with you that it does exist.
Alcohol use disorder is interesting and tricky clinically because chronically, alcohol addiction or alcohol use disorder is associated with an increased risk for diabetes. Acutely, as you point out; and this could be with or without alcohol use disorder. An episode of a high volume of binge drinking may lead to hypoglycemia.
This is one of the reasons why people may show up to the emergency room with intoxication, and one of the symptoms detected at the emergency room is that they also have hypoglycemia in addition to vomiting, nausea, and everything else that we see in patients with acute intoxication.
Similar to the discussion about pancreatitis, as we work on understanding the possible role of GLP-1 RA in patients with alcohol use disorder, we do have to keep a close eye on the risk for hypoglycemia. The short answer is that this is not well established, but based on the simple concept of “first, do no harm,” I think we need to track that very carefully.
In the ongoing clinical trial we’re doing in Maryland in my program at the NIH, we do just that. We are tracking glucose levels. Of course, patients come to clinic weekly, so unless they have symptoms, typically we don’t see anything at the time.
More important, we educate our patients when they go through the consent process. We tell them that this medication per se does not give hypoglycemia. In fact, we’re including people with diabetes, so for people on other medications like metformin, we explain to them that technically such a risk should not exist, but because you’re drinking alcohol in excessive amounts, you do have a potential higher risk. We just don’t know how significant that risk could be.
We do a large amount of education at baseline when they enroll in our study. We also educate our patients on how to recognize early on the potential risk for hypoglycemia, exactly for the reasons you said. We explain to them the unknown potential that the GLP-1 RAs and alcohol together may synergize and give hypoglycemia.
Dr. Jain: I don’t know if you got this feeling at the ADA conference, but I felt, when attending all these sessions, that it seems like GLP-1 RA is the gift that keeps giving. We see the effect on diabetes, obesity, metabolic-associated steatotic liver disease, possibly with Alzheimer’s, chronic obstructive pulmonary disease, and so many things.
Now, of course, there’s potential use in alcohol use disorder. Do you think that using GLP-1 RA therapy is ready for prime time? Do you think we are now ready to prescribe this in people with alcohol use disorder?
Dr. Leggio: I would say we’re not there yet. As I mentioned at the beginning, the evidence keeps on growing. It’s getting stronger and stronger because the positive data keep on coming up. We have data from animal models, including the different species, ranging from rodents to nonhuman primates. We have anecdotal evidence and machine-learning approaches using, for example, big data and social media data. Now we have pharmacoepidemiology data and some small, initial, but still good randomized clinical trials.
What we are missing is the final step of having a substantial number of prospective, double-blind, placebo-controlled clinical trials to really prove or disprove whether these medications work, and to also better understand which patients may respond to these medications.
The good news is that there are many ongoing clinical trials. We are conducting a clinical trial in Maryland at the NIH. Dr. Simmons is doing a clinical trial at Oklahoma State University. Dr. Christian Hendershot at UNC is conducting a study at Chapel Hill. Dr. Josh Gowin is doing a study in Colorado. Dr. Anders Fink-Jensen is doing a study in Denmark. The momentum is very high.
I’m only mentioning those people who are doing alcohol-semaglutide clinical trials. There are also people doing clinical trials on smoking, stimulants, and opioids. There are actually some very fresh, still unpublished data from Penn State that were presented publicly at conferences, showing how these drugs may reduce opioid craving, which is, of course, critically important, given that we’re in the middle of a fentanyl pandemic that is killing one person every 7 minutes, for example, in Baltimore. It’s very alarming and we need more treatments.
The bottom line is that it’s very promising, but we need to wait for these clinical trials to have a definitive answer. I would say that if you have a patient with diabetes, obesity, and also alcohol addiction, and they are on semaglutide or any other GLP-1 RA, and in addition to using the medication for diabetes and obesity, they also have a beneficial effect on their alcohol drinking, then that’s fantastic. At the end of the day, that’s the mission we all share: helping people.
If it’s someone without obesity and diabetes, personally, at this stage, I will go with other medications that either have FDA approval or at least very solid evidence of efficacy from RCTs rather than going with the GLP-1 RA, at least until I see more definitive data from randomized clinical trials.
There is a large amount of hope. We are hoping that these clinical trials will be positive. We are very enthusiastic and we’re also very thrilled to see that Novo Nordisk recently launched a gigantic multisite clinical trial with — I forgot how many sites, but it’s very large across Europe, America, and maybe other continents as well.
Their primary outcome is improvement in alcohol-related liver disease, but they’re also looking at alcohol drinking as a secondary outcome. That’s very important because, unlike in the diabetes field, in the addiction field, we do struggle to build partnership with the private sector because sometimes the addiction field is not seen as an appetitive field from pharma.
We all know that the best success in any medication development story is when you put academia, the government, and pharma together. Think about the COVID-19 vaccine development. That’s unfortunately the exception rather than rule in the addiction field.
With the company doing a large clinical trial in the alcohol field, although they focus more on the liver but they also looked at drinking, I really hope we’ll see more and more companies in the private sector take more and more interest in addiction. Also, I hope to see more and more partnership between the private sector, the government, and academia.
Dr. Jain: Such exciting times, indeed. We can’t wait enough for the results of these and many other trials to come out. Dr. Leggio, it was an absolute delight chatting with you today. Thank you so much for joining us from ADA 2024.

Akshay B. Jain, MD: Today we are very excited to have Dr. Leggio join us all the way from the National Institutes of Health (NIH). He is an addiction physician scientist in the intramural research program at NIH. Welcome, Dr. Leggio. Thanks for joining us.
Lorenzo Leggio, MD, PhD: Thank you so much.
Dr. Jain: We’ll get right into this. Your session was, in my mind, extremely informative. The session looked at glucagon-like peptide 1 receptor agonist (GLP-1 RA) therapy and its potential effects on mitigating alcohol misuse syndrome, so, reduction of alcohol addiction potentially.
We’ve seen in some previous clinical trials, including many from your group, that alcohol use is known to be reduced — the overall risk of incidence, as well as recurrence of alcohol use — in individuals who are on GLP-1 RA therapy.
Can you share more insights about the data already out there?
Dr. Leggio: At the preclinical level, we have a very robust line of studies, experiments, and publications looking at the effect of GLP-1 RAs, starting from exenatide up to, more recently, semaglutide. They show that these GLP-1 RAs do reduce alcohol drinking. They used different animal models of excessive alcohol drinking, using different species — for example, mice, rats, nonhuman primates — models that reflect the excessive alcohol drinking behavior that we see in patients, like physical alcohol dependence or binge-like alcohol drinking, and other behaviors in animal models that reflect the human condition.
In addition to that, we recently have seen an increase in human evidence that GLP-1 RAs may reduce alcohol drinking. For example, there is some anecdotal evidence and some analyses using social media showing that people on GLP-1 RAs report drinking less alcohol.
There are also some pharmacoepidemiology studies which are very intriguing and quite promising. In this case, people have been looking at electronic medical records; they have used the pharmacoepidemiology approaches to match patients on GLP-1 RAs because of diabetes or obesity, and have compared and matched to patients on different drugs as the controls.
A study was recently published Nature Communications by a group in Cleveland in collaboration with Dr. Nora Volkow from the National Institute on Drug Abuse. This study shows the association between being on a GLP-1 RA and the lower incidence of alcohol use disorder and lower drinking.
There is also some promise from prospective randomized clinical trials. In particular, there was one clinical trial from Denmark, a well-known and -conducted clinical trial where they looked at exenatide, and they didn’t see an effect of exenatide compared with placebo in the main analysis. But in a subanalysis, they did see that exenatide reduced alcohol drinking, but only in patients with alcohol use disorder and obesity.
This suggests that these medications may work for some patients and not for other patients. That’s fine, because just like in any other field in medicine, including diabetes, obesity, hypertension, Parkinson’s, and depression, not all medications work for everybody. If these medications will work for alcohol addiction, we do not expect that they will work for everybody.
One ongoing question in the field is to try to identify the phenotypes or the subgroup of people who may be more responsive to these medications.
Dr. Jain: This is such a fascinating field, and all these studies are coming out. In your review of all the literature so far, do you think this is dose dependent? Also, we see that, for instance, with certain individuals, when they take GLP-1 RA therapy, they might have a lot of gastrointestinal (GI) side effects. Recent studies have shown that the rate of these GI side effects does not necessarily correlate with the amount of weight loss. In the alcohol addiction field, do you think that the GI side effects, things like nausea, could also have a potential role in mitigating the alcohol addiction?
Dr. Leggio: This is a great question. They may play a role; they may contribute, too, but we don’t think that they are the driving mechanism of why people drink less, for at least a couple of reasons.
One is that, similar to the obesity field, the data we have so far don’t necessarily show a relationship between the GI side effects and the reduction in drinking. Plus, the reduction in drinking is likely to happen later when many GI side effects are gone or attenuated.
The second reason is from the neuroscience field. We are starting to better understand the mechanism at the brain level as to how these medications work. We don’t see that the nausea or, more generally, not feeling well — malaise, etc. — are driving mechanisms for how these medications work.
Again, it’s not to discount completely that the GI side effects may play a role, but I would say that, if anything, they may be more contributing to. And if they do, that will not be unique to this class of medication. For example, we have three medications approved by the US Food and Drug Administration (FDA) for alcohol use disorder.
One challenge we have in the addiction field is that many people don’t know that these medications exist — many primary care providers don’t know — and they are completely underutilized. Everybody here who is listening to us knows that roughly 85% of people with diabetes receive a medication for diabetes. For alcohol use disorder, the number is 2%. These are medications approved by the FDA.
One of them is naltrexone, which does give GI symptoms — in particular, nausea and vomiting. The other medication is acamprosate, which does give diarrhea.
You have medications approved for alcohol disorder where you do have some GI symptoms, but they are not the mechanism either for how these medications help people to curb craving and reduce alcohol drinking.
Dr. Jain: What about the dose-dependent action? Do you think that GLP-1 RAs, at a lower dose, may not have an effect on alcohol use disorder vs at a higher dose, or is everyone a little different?
Dr. Leggio: That’s a wonderful question. The short answer is, we don’t know, to be honest. Now, in some of the animal studies — my team has been in collaboration with other scientists in the NIH intramural research program, and also with scientists in academia, for example, at Scripps, UCLA — we see a dose response where the higher the dose, the higher the effect of the drug. In this case, semaglutide reduced binge drinking in a rat model of a physical alcohol dependence.
That said, I would be very cautious about claiming, based on the rodent data, that humans will have a dose response. It’s an open question. We really don’t know. Some of the pharmacoepidemiology data suggested that even lower doses — for example, using semaglutide for diabetes without going up to the obesity dose — may be just as effective as a higher dose in reducing the incidence of alcohol use disorder.
It’s important also to keep in mind that the pharmacoepidemiology data are always an association. Reduction in alcohol disorder is associated with the prescription GLP-1 RA, but they don’t really replace the more gold-standard, double-blind, placebo-controlled randomized clinical trial. Nonetheless, with the pharmacoepidemiology data, I think there is an argument to at least hypothesize that people may respond well, even to lower doses.
This also may be important from a safety standpoint.

For example, just anecdotally, I will tell you that in the clinical trial we are conducting right now at the NIH Intramural Research Program, for which I’m the principal investigator (PI), we are going up to 2.4 mg — the highest dose of semaglutide.

I will remind everybody that (1) we do have FDA-approved medications for alcohol addiction; and (2) there are also other medications not approved by the FDA, but with a proven efficacy in some clinical trials — for example, topiramate and gabapentin — and they’ve been endorsed by the American Psychiatric Association.
There is also some evidence for another medication, baclofen, which has been endorsed by the American College of Gastroenterology for patients with alcohol addiction and liver disease.
The point I’m making is that it’s not that either we use the GLP-1 RAs or we have no other tools. We have other tools. I think we have to personalize the treatment based on the patient’s profile from a safety standpoint and from a phenotypic standpoint.
Dr. Jain: I love that thought. I think individualization is the key here.
We know that people with diabetes have a higher risk for pancreatitis by virtue of having diabetes. People with obesity also have a higher risk for pancreatitis by virtue of having obesity. These are the two conditions where we are using a large amount of GLP-1 RA therapy. Again, the idea is looking at the person in front of us and then deciding, based on their past medical history and their current risk, whether or not a medication is a right fit for them.
I think more individualization here will come as we start using these medications that might be having potential effects on different organ systems. You mentioned a little bit about the liver, so a thought came in my mind. We know that people with diabetes who have alcohol use disorder are at a higher risk for potential hypoglycemia. If they have events when they have increased consumption of alcohol, there can be more hypoglycemia.
We now could potentially be using semaglutide or other GLP-1 RA therapy for management of alcohol use disorder. In your own experience in the studies that you’ve done or the literature that’s out there, has that been associated with an even higher risk for hypoglycemia?
Dr. Leggio: It’s a wonderful question. I’m not aware of any formal and published report of that association. That said, your thinking from a physiopathologist standpoint makes total sense. I could not agree more. The fact that nothing has been published, at least to my knowledge, doesn’t mean that the death risk doesn’t exist. In fact, I agree with you that it does exist.
Alcohol use disorder is interesting and tricky clinically because chronically, alcohol addiction or alcohol use disorder is associated with an increased risk for diabetes. Acutely, as you point out; and this could be with or without alcohol use disorder. An episode of a high volume of binge drinking may lead to hypoglycemia.
This is one of the reasons why people may show up to the emergency room with intoxication, and one of the symptoms detected at the emergency room is that they also have hypoglycemia in addition to vomiting, nausea, and everything else that we see in patients with acute intoxication.
Similar to the discussion about pancreatitis, as we work on understanding the possible role of GLP-1 RA in patients with alcohol use disorder, we do have to keep a close eye on the risk for hypoglycemia. The short answer is that this is not well established, but based on the simple concept of “first, do no harm,” I think we need to track that very carefully.
In the ongoing clinical trial we’re doing in Maryland in my program at the NIH, we do just that. We are tracking glucose levels. Of course, patients come to clinic weekly, so unless they have symptoms, typically we don’t see anything at the time.
More important, we educate our patients when they go through the consent process. We tell them that this medication per se does not give hypoglycemia. In fact, we’re including people with diabetes, so for people on other medications like metformin, we explain to them that technically such a risk should not exist, but because you’re drinking alcohol in excessive amounts, you do have a potential higher risk. We just don’t know how significant that risk could be.
We do a large amount of education at baseline when they enroll in our study. We also educate our patients on how to recognize early on the potential risk for hypoglycemia, exactly for the reasons you said. We explain to them the unknown potential that the GLP-1 RAs and alcohol together may synergize and give hypoglycemia.
Dr. Jain: I don’t know if you got this feeling at the ADA conference, but I felt, when attending all these sessions, that it seems like GLP-1 RA is the gift that keeps giving. We see the effect on diabetes, obesity, metabolic-associated steatotic liver disease, possibly with Alzheimer’s, chronic obstructive pulmonary disease, and so many things.
Now, of course, there’s potential use in alcohol use disorder. Do you think that using GLP-1 RA therapy is ready for prime time? Do you think we are now ready to prescribe this in people with alcohol use disorder?
Dr. Leggio: I would say we’re not there yet. As I mentioned at the beginning, the evidence keeps on growing. It’s getting stronger and stronger because the positive data keep on coming up. We have data from animal models, including the different species, ranging from rodents to nonhuman primates. We have anecdotal evidence and machine-learning approaches using, for example, big data and social media data. Now we have pharmacoepidemiology data and some small, initial, but still good randomized clinical trials.
What we are missing is the final step of having a substantial number of prospective, double-blind, placebo-controlled clinical trials to really prove or disprove whether these medications work, and to also better understand which patients may respond to these medications.
The good news is that there are many ongoing clinical trials. We are conducting a clinical trial in Maryland at the NIH. Dr. Simmons is doing a clinical trial at Oklahoma State University. Dr. Christian Hendershot at UNC is conducting a study at Chapel Hill. Dr. Josh Gowin is doing a study in Colorado. Dr. Anders Fink-Jensen is doing a study in Denmark. The momentum is very high.
I’m only mentioning those people who are doing alcohol-semaglutide clinical trials. There are also people doing clinical trials on smoking, stimulants, and opioids. There are actually some very fresh, still unpublished data from Penn State that were presented publicly at conferences, showing how these drugs may reduce opioid craving, which is, of course, critically important, given that we’re in the middle of a fentanyl pandemic that is killing one person every 7 minutes, for example, in Baltimore. It’s very alarming and we need more treatments.
The bottom line is that it’s very promising, but we need to wait for these clinical trials to have a definitive answer. I would say that if you have a patient with diabetes, obesity, and also alcohol addiction, and they are on semaglutide or any other GLP-1 RA, and in addition to using the medication for diabetes and obesity, they also have a beneficial effect on their alcohol drinking, then that’s fantastic. At the end of the day, that’s the mission we all share: helping people.
If it’s someone without obesity and diabetes, personally, at this stage, I will go with other medications that either have FDA approval or at least very solid evidence of efficacy from RCTs rather than going with the GLP-1 RA, at least until I see more definitive data from randomized clinical trials.
There is a large amount of hope. We are hoping that these clinical trials will be positive. We are very enthusiastic and we’re also very thrilled to see that Novo Nordisk recently launched a gigantic multisite clinical trial with — I forgot how many sites, but it’s very large across Europe, America, and maybe other continents as well.
Their primary outcome is improvement in alcohol-related liver disease, but they’re also looking at alcohol drinking as a secondary outcome. That’s very important because, unlike in the diabetes field, in the addiction field, we do struggle to build partnership with the private sector because sometimes the addiction field is not seen as an appetitive field from pharma.
We all know that the best success in any medication development story is when you put academia, the government, and pharma together. Think about the COVID-19 vaccine development. That’s unfortunately the exception rather than rule in the addiction field.
With the company doing a large clinical trial in the alcohol field, although they focus more on the liver but they also looked at drinking, I really hope we’ll see more and more companies in the private sector take more and more interest in addiction. Also, I hope to see more and more partnership between the private sector, the government, and academia.
Dr. Jain: Such exciting times, indeed. We can’t wait enough for the results of these and many other trials to come out. Dr. Leggio, it was an absolute delight chatting with you today. Thank you so much for joining us from ADA 2024.

Akshay B. Jain, MD: Today we are very excited to have Dr. Leggio join us all the way from the National Institutes of Health (NIH). He is an addiction physician scientist in the intramural research program at NIH. Welcome, Dr. Leggio. Thanks for joining us.
Lorenzo Leggio, MD, PhD: Thank you so much.
Dr. Jain: We’ll get right into this. Your session was, in my mind, extremely informative. The session looked at glucagon-like peptide 1 receptor agonist (GLP-1 RA) therapy and its potential effects on mitigating alcohol misuse syndrome, so, reduction of alcohol addiction potentially.
We’ve seen in some previous clinical trials, including many from your group, that alcohol use is known to be reduced — the overall risk of incidence, as well as recurrence of alcohol use — in individuals who are on GLP-1 RA therapy.
Can you share more insights about the data already out there?
Dr. Leggio: At the preclinical level, we have a very robust line of studies, experiments, and publications looking at the effect of GLP-1 RAs, starting from exenatide up to, more recently, semaglutide. They show that these GLP-1 RAs do reduce alcohol drinking. They used different animal models of excessive alcohol drinking, using different species — for example, mice, rats, nonhuman primates — models that reflect the excessive alcohol drinking behavior that we see in patients, like physical alcohol dependence or binge-like alcohol drinking, and other behaviors in animal models that reflect the human condition.
In addition to that, we recently have seen an increase in human evidence that GLP-1 RAs may reduce alcohol drinking. For example, there is some anecdotal evidence and some analyses using social media showing that people on GLP-1 RAs report drinking less alcohol.
There are also some pharmacoepidemiology studies which are very intriguing and quite promising. In this case, people have been looking at electronic medical records; they have used the pharmacoepidemiology approaches to match patients on GLP-1 RAs because of diabetes or obesity, and have compared and matched to patients on different drugs as the controls.
A study was recently published Nature Communications by a group in Cleveland in collaboration with Dr. Nora Volkow from the National Institute on Drug Abuse. This study shows the association between being on a GLP-1 RA and the lower incidence of alcohol use disorder and lower drinking.
There is also some promise from prospective randomized clinical trials. In particular, there was one clinical trial from Denmark, a well-known and -conducted clinical trial where they looked at exenatide, and they didn’t see an effect of exenatide compared with placebo in the main analysis. But in a subanalysis, they did see that exenatide reduced alcohol drinking, but only in patients with alcohol use disorder and obesity.
This suggests that these medications may work for some patients and not for other patients. That’s fine, because just like in any other field in medicine, including diabetes, obesity, hypertension, Parkinson’s, and depression, not all medications work for everybody. If these medications will work for alcohol addiction, we do not expect that they will work for everybody.
One ongoing question in the field is to try to identify the phenotypes or the subgroup of people who may be more responsive to these medications.
Dr. Jain: This is such a fascinating field, and all these studies are coming out. In your review of all the literature so far, do you think this is dose dependent? Also, we see that, for instance, with certain individuals, when they take GLP-1 RA therapy, they might have a lot of gastrointestinal (GI) side effects. Recent studies have shown that the rate of these GI side effects does not necessarily correlate with the amount of weight loss. In the alcohol addiction field, do you think that the GI side effects, things like nausea, could also have a potential role in mitigating the alcohol addiction?
Dr. Leggio: This is a great question. They may play a role; they may contribute, too, but we don’t think that they are the driving mechanism of why people drink less, for at least a couple of reasons.
One is that, similar to the obesity field, the data we have so far don’t necessarily show a relationship between the GI side effects and the reduction in drinking. Plus, the reduction in drinking is likely to happen later when many GI side effects are gone or attenuated.
The second reason is from the neuroscience field. We are starting to better understand the mechanism at the brain level as to how these medications work. We don’t see that the nausea or, more generally, not feeling well — malaise, etc. — are driving mechanisms for how these medications work.
Again, it’s not to discount completely that the GI side effects may play a role, but I would say that, if anything, they may be more contributing to. And if they do, that will not be unique to this class of medication. For example, we have three medications approved by the US Food and Drug Administration (FDA) for alcohol use disorder.
One challenge we have in the addiction field is that many people don’t know that these medications exist — many primary care providers don’t know — and they are completely underutilized. Everybody here who is listening to us knows that roughly 85% of people with diabetes receive a medication for diabetes. For alcohol use disorder, the number is 2%. These are medications approved by the FDA.
One of them is naltrexone, which does give GI symptoms — in particular, nausea and vomiting. The other medication is acamprosate, which does give diarrhea.
You have medications approved for alcohol disorder where you do have some GI symptoms, but they are not the mechanism either for how these medications help people to curb craving and reduce alcohol drinking.
Dr. Jain: What about the dose-dependent action? Do you think that GLP-1 RAs, at a lower dose, may not have an effect on alcohol use disorder vs at a higher dose, or is everyone a little different?
Dr. Leggio: That’s a wonderful question. The short answer is, we don’t know, to be honest. Now, in some of the animal studies — my team has been in collaboration with other scientists in the NIH intramural research program, and also with scientists in academia, for example, at Scripps, UCLA — we see a dose response where the higher the dose, the higher the effect of the drug. In this case, semaglutide reduced binge drinking in a rat model of a physical alcohol dependence.
That said, I would be very cautious about claiming, based on the rodent data, that humans will have a dose response. It’s an open question. We really don’t know. Some of the pharmacoepidemiology data suggested that even lower doses — for example, using semaglutide for diabetes without going up to the obesity dose — may be just as effective as a higher dose in reducing the incidence of alcohol use disorder.
It’s important also to keep in mind that the pharmacoepidemiology data are always an association. Reduction in alcohol disorder is associated with the prescription GLP-1 RA, but they don’t really replace the more gold-standard, double-blind, placebo-controlled randomized clinical trial. Nonetheless, with the pharmacoepidemiology data, I think there is an argument to at least hypothesize that people may respond well, even to lower doses.
This also may be important from a safety standpoint.
Basically, we need to wait for results in the next years to come from randomized clinical trials to better unfold the question about doses. For example, just anecdotally, I will tell you that in the clinical trial we are conducting right now at the NIH Intramural Research Program, for which I’m the principal investigator (PI), we are going up to 2.4 mg — the highest dose of semaglutide.
We are collaborating with Kyle Simmons, PhD, from Oklahoma State University. Our two studies are not like a two-site clinical trial, but they are harmonized. In Dr. Simmons’ clinical trial, they’re going up to 1.0 mg. We are excited about this team approach because the trials are slightly different, but they’re harmonized to the point that, once the studies are done, we’ll be able to combine and compare data to better answer the question about dosing, and many other questions.
Dr. Jain: From a clinical perspective, we see that many people who are battling alcohol use disorder may not have obesity. They might actually be on the leaner side, and hence, we may not want to use a high dose of GLP-1 RA therapy. It’ll be very exciting to see when these results come out.
This brings me to the next question. I think everyone would love to know why this happens. Why is GLP-1 RA having this effect on alcohol use disorder? I know that your group has done many animal studies, as you pointed out, and one of the postulated theories was the effect on the GABA neurotransmission pathway.
Can you tell us more about what you feel is the underlying mechanism of action here?
Dr. Leggio: I will start by saying that we don’t fully know. There are many open questions. If I can sidetrack for one second: We come up with the idea that, first of all, alcohol use disorder and substance use disorder are addictive behaviors, addictive disorders. We define addiction as a brain disease.
Granted that addiction is a brain disease, it doesn’t mean that addiction works just in the brain in isolation. As we all know, the brain works in concert with the rest of the body. One specific approach my team has been taking is working on the analogy and the similarities between obesity and addiction to try to understand how the body-brain connection, such as the gut-brain-neuroendocrine pathway, may play a role in patients with addiction.
With that in mind, a large amount of work in my lab in the past 20 years — since I’ve been a PI — has been focused on studying this neuroendocrine pathways related to the gut-brain axis. For example, we have done work on insulin and leptin, primarily; we had done work on ghrelin, and since 2015 on the GLP-1 RAs.
With that in mind, the framework we are working on, which is also substantiated by many studies done by our team and other teams in the neuroscience field, kind of supports the idea that, similar to what we see in obesity, these medications may work by affecting what we call reward processing, or the seeking for addictive drugs, such as alcohol, and also the drugs such as the stimulants, opioids, nicotine, and so on.
The idea is that the mechanism is driven by the ability of the medication — semaglutide and all the GLP-1 RAs — to reduce the rewarding properties of alcohol and drugs. To maybe make the example more pragmatic, what does that mean? It means, for example, that a patient who typically has 10 drinks per day in the afternoon and night, while they are on the medication they may feel the lack of need to drink up to 10 to feel the same reward.
They may be able to stop after two or three drinks, which means a significant harm reduction and a beneficial outcome. This also brings us to another mechanism, which may be related to society. We don’t fully understand how much the society mechanism, including society mechanism related to GI motility, may also play a role.
With that said, we don’t think that the effect of the GLP-1 RAs is merely due to alcohol being a calorie-based nutrient because, in fact, we see alcohol as an addictive drug, not as a nutrient. Also, the GLP-1 RAs, at least in animal models, seem to work on other addictive drugs that don’t have calories, such as nicotine, and possibly with cannabis, opioids, and stimulants.
Then on the molecular level, our team recently showed, in collaboration with Dr. Marisa Roberto from Scripps in La Jolla, California, that semaglutide may in fact change the GABA transmission at the level of some brain regions, such as the amygdala and the prefrontal cortex. These are brain regions that are well-established hubs that play a role in the mechanism underlying addiction.
There are also some very exciting recent data showing how these medications may work not just on GABA or just on dopamine, which is the canonical way we conceive of reward processing, but by working on both by modulating GABA transmission — for example, at the ventral tegmental area and dopamine transmission at the nucleus accumbens.
Bottom line, if I summarize all of this, is that the mechanism is not fully understood, but there is definitely a contribution of this medication to effect and reward processing, possibly by altering the balance between GABA and dopamine. There are still some unknown questions, such as, are these mechanisms all brain driven or are they signaling from the periphery to the brain, or maybe both?
Also, as we all know, there are many differences across all these GLP-1 analogs in brain penetrance. Whether the drug needs to go to the brain to have an effect on alcohol drinking, cocaine seeking, or smoking is really an open question.
Dr. Jain: This is so thought-provoking. I guess the more we uncover, the more mesmerized we get with all the potential crosstalk. There is a large amount of overlap in the brain with each of these different things and how it all interplays with each other.
Speaking of interplay, I’m thinking about how many people prone to having alcohol use disorder can potentially develop complications, one of these being chronic pancreatitis. This is a well-known complication that can occur in people having alcohol addiction. Along that same line, we know that previous history of pancreatitis is considered a use-with-caution, or we don’t want to use GLP-1 RA therapy in people who have had pancreatitis.
Now it becomes this quagmire where people may have chronic pancreatitis, but we may want to consider GLP-1 RA therapy for management of alcohol use disorder. What are your thoughts about this, and the safety, potentially, in using it in these patients?
Dr. Leggio: This is another wonderful question. That’s definitely a top priority in our mind, to address these kinds of questions. For example, our RCT does have, as core primary outcomes, not only the efficacy defined as a reduction in alcohol drinking, but also safety.
The reason is exactly what you just explained. There are many unanswered questions, including whether giving a GLP-1 RA and alcohol together may have synergistic effects and increase the likelihood of having pancreatitis.
The good news is that, so far, based on the published literature, including the RCT done with exenatide in Denmark and published in 2022 and also the ongoing clinical trials — including my own clinical trial, but of course we are blind — pancreatitis has not been coming out as an adverse event.
However, it’s also true that it often happens in clinical medication development. Of course, we screen and select our population well. For example, we do exclude people who have a history of pancreatitis. We exclude people with high lipase or with any of the clinical symptomatology that makes us concerned about these people having pancreatitis.
As often happens when you move a medication from clinical trials to clinical practice, we still need to understand whether this medication works in patients. I’m just speculating, but even if the clinical trials do not raise red flags in terms of increased risk for some side effects such as pancreatitis, I think it will be very important for practitioners to keep a close eye on the death risk regardless.
It’s very interesting that it’s similar to alcohol liver disease. With pancreatitis, not every single patient with alcohol addiction has pancreatitis. We don’t really fully understand why some people develop pancreatitis and some people do not. The point being that there are many patients with alcohol addiction who don’t have pancreatitis and may benefit from these medications if they work. Again, we have to prove that in patients.
On the other side, as we all know, pancreatitis is a potentially life-threatening condition for those people who either have it or are at risk for it. I think we have to be very careful before we consider giving them a GLP-1 RA.
One could argue that alcohol is the leading cause of mortality and morbidity in the world. For example, right now, alcohol is the leading cause of liver disease. It’s the main reason for liver transplantation in our country. Alcohol is affecting thousands of people in terms of death and emergency room visits.
You could argue that the downside is not treating these people and they die because of alcohol addiction. A GLP-1 RA is not going to be for everybody. I will remind everybody that (1) we do have FDA-approved medications for alcohol addiction; and (2) there are also other medications not approved by the FDA, but with a proven efficacy in some clinical trials — for example, topiramate and gabapentin — and they’ve been endorsed by the American Psychiatric Association.
There is also some evidence for another medication, baclofen, which has been endorsed by the American College of Gastroenterology for patients with alcohol addiction and liver disease.
The point I’m making is that it’s not that either we use the GLP-1 RAs or we have no other tools. We have other tools. I think we have to personalize the treatment based on the patient’s profile from a safety standpoint and from a phenotypic standpoint.

Hormone Therapy Can Benefit Women into Their 80s
Hormone therapy (HT) can help women manage menopause symptoms into their 80s and the reasons are varied, according to a retrospective analysis being presented at the annual meeting of The Menopause Society.
“It’s important to know that this is a preselected group of women who had no contraindications to continuing their hormone therapy,” senior author Wendy Wolfman, MD, director of the Menopause Clinic and The Premature Ovarian Insufficiency Clinic at Mount Sinai Hospital in Toronto, Ontario, Canada, said in an interview. “They had the initiation of hormone therapy closer to menopause and carried on their hormones. We followed them for a long time and basically saw no real concerns about taking the hormones and the patients did very well. It’s important to emphasize this was not the new initiation of hormone therapy in elderly women.”
She said that, in her large tertiary referral center, “I still see patients who are referred who are told that they have to stop their hormones after 5 years based on a false assumption. Everybody ages at different rates and everybody has different risk factors.”
About 70%-80% of women experience menopause symptoms that restrict quality of life and productivity, the authors noted. HT has consistently been the most effective means for managing many of the side effects, especially hot flashes.
Hot flashes last on average 7-11 years. But they continue in up to 40% of women in their 60s and 10%-15% in their 70s, the authors wrote.
The analysis included more than 100 women in Canada older than 65 who continue to use HT and explored the motivations of the women to use them.
The average age of the women was 71 and nearly 8% were age 80 or older. The mean age for starting HT was 52 years and the women continued HT for an average 18 years, though 42% used it regularly for more than 20 years. Most of the women (nearly 88%) used a transdermal form of estrogen; only 12% used oral estrogen pills. Fewer than 5% of participants used synthetic progestins.
Controlling hot flashes was the No. 1 reason the women continued HT beyond age 65 (55%), followed by a desire for a better quality of life (29%), and to reduce chronic pain and arthritis symptoms (7%).
Some adverse effects were reported – postmenopausal bleeding was the most common – but no strokes, myocardial infarctions, or uterine cancers were documented.
More than one fourth (26.4%) of the women tried stopping HT once, but 87% reported that the return of hot flashes was the main reason to restart HT.
In addition, “many women choose to continue hormone therapy long term for relief of nonvasomotor symptoms, preservation of bone density, and a desire to benefit from potential long-term cardiovascular protection,” said Lauren F. Streicher, MD, Professor of Obstetrics and Gynecology at Feinberg School of Medicine at Northwestern University in Chicago, who was not part of the research.
In 2022, The Menopause Society position statement on hormone therapy acknowledged that, on an individual basis, it is appropriate for women to continue hormone therapy long term with counseling on benefits and risks.
“However, few studies have evaluated the outcomes of using hormone therapy for more than 10 years, and individual motivation for doing so,” Dr. Streicher said. She pointed to a study that analyzed the insurance records of more than 10 million women who continued their HT past the age of 65 and reassuringly found that there were significant risk reductions in all-cause mortality, breast cancer, lung cancer, colorectal cancer, heart failure, venous thromboembolism, atrial fibrillation, acute myocardial infarction, and dementia. In that study, however, the reasons women chose to continue hormone therapy were not specified.
“In this retrospective Canadian study,” she noted, “the outcomes were again reassuring, with no increase in strokes, myocardial infarctions, or uterine cancers. The reasons cited for continuing hormone therapy were not just to treat ongoing vasomotor symptoms, but also other menopause symptoms such as musculoskeletal aches and pains, and overall quality of life.
Dr. Streicher said that, while long-term longitudinal studies are needed to make definitive recommendations, “It is reassuring that women who choose to extend hormone therapy can safely do so. It is irresponsible, cruel, and nonsensical to continue to make blanket statements that hormone therapy should be discontinued based on age or years of use and commit women to enduring symptoms and depriving them of possible long-term benefits.”
