An increasing proportion of people are using cannabis products for pain, including that associated with gynecologic conditions, according to new guidance from the American College of Obstetricians and Gynecologists. The organization published its first guidance in July on the use of cannabis products for gynecologic pain.

“Many of our patients are using these products and many of our members are getting questions from their patients asking whether they should be using them,” Kimberly Gecsi, MD, a professor of ob.gyn. at Medical College of Wisconsin and Froedtert Health in Milwaukee, Wisconsin, and one of the document’s coauthors, said in an interview.* “We want ACOG members to walk away with some understanding that their patients are using these products, what the different products are, and the current state of the science so they can guide their patients about the potential advantages as well as the potential risks.”

Use of cannabis in the past month in the United States rose 38.2% between 2015 and 2019, according to the National Survey on Drug Use and Health. Other research using data from that survey found that US use of cannabis for medicinal purposes more than doubled, from 1.2% to 2.5% between 2013-2014 and 2019-2020, and use in states where it was legalized increased fourfold. Though little data exist on its use for gynecologic pain, at least one peer-reviewed online survey found that 61% of those who had never used it and 90% of those who had ever used it were willing to consider its use for gynecologic pain.

In assessing the current evidence, the researchers excluded studies looking at use of cannabis to manage symptoms related to cancer, obstetrics, or gynecologic malignancy. Of the remaining evidence, however, “there just isn’t enough data on gynecologic pain to really have tipped the scale toward a recommendation,” Dr. Gecsi said.

The consensus recommendations therefore state that current data are not sufficient to recommend or discourage use of cannabis products to treat pain linked to gynecologic conditions. Yet the potential for benefit suggests that “if they are already using these products, there’s no need to discourage them, especially if the patients feel they are getting some benefit from them,” Dr. Gecsi said.

The guidance also highlights the importance of clinicians being aware that their patients may be using these products and being prepared to discuss with them the limited data available as well as the theoretical benefits and potential negative effects for adult patients. In adolescent patients, however, the increased risk of negative cognitive effects and psychotic conditions currently appears to outweigh the theoretical benefits. Use of cannabis products in teens should therefore not be recommended until more data is available on the short-term and long-term effects of its use on adolescent brain development, the authors wrote.

Josephine Urbina, MD, MAS, an assistant professor of ob.gyn. and reproductive sciences at the University of California, San Francisco, said that the guidance confirms what most ob.gyns. suspected regarding the lack of data to support or refute the use of cannabis.

“Patients usually see cannabis as a last resort to control their pain,” Dr. Urbina added. “It seems that this decision to start using cannabis isn’t one that’s taken lightly, and they’re usually at their wits’ end. Some patients use cannabis as an adjunct so that they don’t have to rely on stronger pain medications like opioids, which we all know have a proven track record for being addicting.”

The ACOG guidance notes limited survey data suggesting that cannabis may help reduce patients’ use of opioids for pain relief, though there’s not enough data to confirm this potential benefit. The authors also highlight the limited data suggesting that PEA-transpolydatin may be effective for relieving pain related to primary dysmenorrhea, endometriosis, and chronic pelvic pain, but, again, there’s not yet enough data to formally recommend its use.

Current treatments for pain from gynecologic conditions depend on the cause of the pain, Dr. Gecsi said. One of the more common causes of pain, for example, is endometriosis, which can be treated with medications, including hormonal ones, or with surgery.

Other first-line treatments for pain, can include nonsteroidal anti-inflammatory drug and, for more complex cases, gonadotropin-releasing hormone agonists, antidepressants, and anticonvulsants. “Nonpharmacological treatments like physical therapy, acupuncture, cognitive-behavioral therapy and lifestyle changes, including diet and exercise, can also be beneficial,” Dr. Urbina added.

The new guidance also attempts to clarify the confusing legal landscape associated with cannabis use. In addition to the patchwork of state laws, federal distinctions in cannabis legality have been shifting in recent years. The 2018 Farm Bill defined any product with 0.3% or less tetrahydrocannabinol (THC) as hemp, which is now legal and commercially available in all states. That change introduced a wide range of topical and edible cannabidiol products to the market, even in states where marijuana is otherwise still illegal.

Products with a THC concentration greater than 0.3%, however, remain classified as a Schedule I drug, though the Justice Department proposed a rule in May to change that classification to Schedule III, which includes drugs such as ketamine, anabolic steroids, testosterone, and Tylenol with codeine. The guidance also includes a box of definitions for different types of cannabis products and differences in bioavailability, time to onset of effects, and duration of effects for different routes of exposure.

Kiran Kavipurapu, DO, JD, MPH, an assistant clinical professor and ob.gyn. residency program director at the University of California, Los Angeles, said the increasing availability and legalization of cannabis has meant that more patients are coming to their doctors’ offices having already tried it for medicinal purposes.

“Cannabis use discussions are often initiated by patients who are either inquiring about its benefits or because they have already tried it and want a physician to weigh in,” Dr. Kavipurapu said in an interview. “Over the past 5 years or so, this has become an increasingly common topic along with discussion of herbal or naturopathic remedies to supplement treatment of gynecologic conditions.”

Yet stigma about its use can lead patients to feel hesitant about bringing it up, Dr. Kavipurapu added. “I think it is necessary for clinicians to create a safe environment for patients to discuss their use of any and all therapies or supplements so their physician can assess for potential drug interactions or other harmful effects,” he said.

Dr. Gecsi agreed that this need to reassure patients was an important aspect of ACOG’s new guidance. Clinicians “should make sure that they strive to always foster a relationship with their patients where their patients can feel safe sharing their use and other things going on in their lives without feeling like they’re going to get in trouble,. Our job is not to put our patients at risk for any kind of legal or criminal problems.”

Meanwhile, the legal restrictions on cannabis remain a substantial barrier to the additional research that’s needed to make more informed recommendations about its use to patients, Dr. Gecsi said. But the inadequate amount of research goes beyond the challenges of studying cannabis in particular, Dr. Urbina noted.

“The paucity of research in women’s health, particularly in the realm of sexual and reproductive health care, underscores the urgent need to prioritize this topic in order to ensure comprehensive and equitable healthcare for women,” Dr. Urbina said. Underrepresentation of women’s health issues in clinical studies has led to knowledge gaps and “suboptimal treatment options for conditions unique to or more prevalent among women,” and it’s another reason for the lack of robust data on cannabis use for gynecologic-related pain.

“Prioritizing research in women’s health is essential to developing effective interventions, understanding gender-specific responses to treatments, and addressing the complex interplay of biological, social, and psychological factors affecting women’s well-being,” Dr. Urbina said. “Furthermore, advancing reproductive health research supports women’s reproductive autonomy, empowering them with the knowledge and resources to make informed decisions about their bodies and lives. By investing in robust, inclusive research, we can close existing gaps, improve health outcomes, and promote gender equity in healthcare — something that has been long overdue in this country.”

The guidance did not use external funding. Dr. Gecsi, Dr. Urbina, and Dr. Kavipurapu had no disclosures.

An electronic health record (EHR)–based nudge intervention could reduce potentially unnecessary sentinel lymph node biopsies (SLNB) among older women with early-stage breast cancer, the authors of new research say.

Participating surgeons noted that the reminder system added minimal friction to their workflow, as it did not require additional clicks or actions on the day of the patient visit, reported lead author Neil Carleton, PhD, of UPMC Hillman Cancer Center, Pittsburgh, and colleagues in JAMA Surgery (JAMA Surg. 2024 Jul 17. doi: 10.1001/jamasurg.2024.2407).

This effort to reduce the rate of SLNB stems from the Choosing Wisely campaign, which recommends against axillary staging in women 70 years and older with early-stage, clinically node-negative (cN0), hormone receptor–positive (HR+) breast cancer, the investigators said.

“These recommendations were developed because axillary staging did not impact survival, and rates of SLN positivity were low because of the tumor’s biological phenotype,” they wrote. “Even in older patients with tumors that exhibit concerning clinicopathologic features, limited nodal involvement does not often alter receipt of chemotherapy independently from genomic testing. Despite these recommendations, most women still receive axillary surgery.”
 

How Did the Nudge System Aim to Reduce the Rate of SLNB?

The nudge intervention involved adding a new column to the Epic schedule view, which flagged eligible patients during their first outpatient surgical consultation. The flag appeared as a caution sign or red clipboard icon. When surgeons hovered over the icon, a text box appeared, reminding them to consider omitting SLNB after a detailed review of core biopsy pathology and ultrasonographic imaging.

The intervention was evaluated at eight outpatient clinics within an integrated healthcare system that included seven breast surgical oncologists.

The study began with a 12-month preintervention period to serve as a control, during which time SLNB rate was determined via 194 patients in the target demographic. SLNB rate was again collected during the 12-month intervention period, which involved 193 patients meeting enrollment criteria. Between these periods, the investigators conducted a brief session lasting less than 30 minutes to introduce the surgeons to the rationale and design of the nudge column.
 

How Effective Was the Nudge System?

The intervention reduced the SLNB rate from 46.9% to 23.8%, representing a 49.3% decrease in use of SLNB. Efficacy was further supported by a significant reduction in SLNB according to an interrupted time series model (adjusted odds ratio, 0.26; 95% confidence interval, 0.07 to 0.90; P = .03). Extended follow-up showed that this effect was durable beyond the intervention period, with a 6-month mean reduction in SLNB of 15.6%.

Omission of SLNB led to higher rates of pathological node positivity during the intervention period (15.2% vs 8.8%), with all positive cases staged as pN1. Adjuvant therapy recommendations were similar between groups and driven by genomic testing, not nodal status. The intervention period also saw a decrease in referrals for lymphedema evaluation (3.6% vs. 6.2%).

How Might the Nudge System Be Implemented in Other Practices?

Although the SLNB nudge system was effective in the present study, likelihood of uptake among practices could vary widely, according to Anne M. Wallace, MD, professor of clinical surgery at UC San Diego Health and director of the Moores Comprehensive Breast Health Program.

On a fundamental level, not all centers use Epic software, which could present issues with compatibility, Dr. Wallace said in an interview. More importantly, she added, many institutions already have EHR-based alerts and reminders in place, so it is not always feasible to add a new nudge for every possible clinical scenario.

“Already there are so many little icons that we have to go through now when we close a note,” she said. “That’s why electronic medical records are becoming one of the leading stressors in medicine.”

This presents a more complex challenge, Dr. Wallace said, particularly as potentially practice-changing data are becoming available, and physicians may not have time to learn about them and integrate them into routine practice. She suggested that the present system may be most appropriate for oncologists in solo practice, or in small group practices where it is more challenging to have routine conversations about changing standards of care.

What Are the Risks of Using the Nudge System?

One of those conversations may surround the validity of the recommendation implemented in the present study.

Although the Society of Surgical Oncology recommends against SLNB in the described demographic, other experts, including Dr. Wallace, take a more nuanced view of the decision.

She noted that some patients with a chronological age of 70 may have a lower biological age, casting doubt on the legitimacy of the age threshold, and those near the threshold may wish to make the decision about staging for themselves.

Beyond these concerns, Dr. Wallace described two potential risks involved in forgoing SLNB.

First, there’s the potential for underestimating the tumor’s severity, she said, as this could mean a trip back to the operating room. A tumor initially thought to be low-grade might later be found to be high-grade, necessitating further surgery. Some patients might refuse additional surgery, leaving the more aggressive tumor untreated.

Second, the nudge system could complicate radiation treatment decisions, Dr. Wallace said. Without full nodal status, some radiation oncologists might push for additional radiation therapy, which incurs a greater treatment burden than SNLB.
 

What Are Some Alternatives to the Nudge System?

After discussing the strengths and weaknesses of the present EHR-based nudge system, and others like it, Dr. Wallace returned to the importance of ongoing communication among colleagues managing complex cases.

At UC San Diego Health, where oncologists meet weekly for a 2-hour breast cancer conference, “we nudge each other,” she said.

This study was supported by the Shear Family Foundation, UPMC eRecord Ambulatory Decision Support and Analytics, UPMC Hillman Cancer Center Biostatistics Facility, and National Institutes of Health. The investigators disclosed relationships with Pfizer, Amgen, the Lewin Group, and Milestone Pennsylvania, and others.

Second, the nudge system could complicate radiation treatment decisions, Dr. Wallace said. Without full nodal status, some radiation oncologists might push for additional radiation therapy, which incurs a greater treatment burden than SNLB.
 

What Are Some Alternatives to the Nudge System?

After discussing the strengths and weaknesses of the present EHR-based nudge system, and others like it, Dr. Wallace returned to the importance of ongoing communication among colleagues managing complex cases.

At UC San Diego Health, where oncologists meet weekly for a 2-hour breast cancer conference, “we nudge each other,” she said.

This study was supported by the Shear Family Foundation, UPMC eRecord Ambulatory Decision Support and Analytics, UPMC Hillman Cancer Center Biostatistics Facility, and National Institutes of Health. The investigators disclosed relationships with Pfizer, Amgen, the Lewin Group, and Milestone Pennsylvania, and others.

An electronic health record (EHR)–based nudge intervention could reduce potentially unnecessary sentinel lymph node biopsies (SLNB) among older women with early-stage breast cancer, the authors of new research say.

Participating surgeons noted that the reminder system added minimal friction to their workflow, as it did not require additional clicks or actions on the day of the patient visit, reported lead author Neil Carleton, PhD, of UPMC Hillman Cancer Center, Pittsburgh, and colleagues in JAMA Surgery (JAMA Surg. 2024 Jul 17. doi: 10.1001/jamasurg.2024.2407).

This effort to reduce the rate of SLNB stems from the Choosing Wisely campaign, which recommends against axillary staging in women 70 years and older with early-stage, clinically node-negative (cN0), hormone receptor–positive (HR+) breast cancer, the investigators said.

“These recommendations were developed because axillary staging did not impact survival, and rates of SLN positivity were low because of the tumor’s biological phenotype,” they wrote. “Even in older patients with tumors that exhibit concerning clinicopathologic features, limited nodal involvement does not often alter receipt of chemotherapy independently from genomic testing. Despite these recommendations, most women still receive axillary surgery.”
 

How Did the Nudge System Aim to Reduce the Rate of SLNB?

The nudge intervention involved adding a new column to the Epic schedule view, which flagged eligible patients during their first outpatient surgical consultation. The flag appeared as a caution sign or red clipboard icon. When surgeons hovered over the icon, a text box appeared, reminding them to consider omitting SLNB after a detailed review of core biopsy pathology and ultrasonographic imaging.

The intervention was evaluated at eight outpatient clinics within an integrated healthcare system that included seven breast surgical oncologists.

The study began with a 12-month preintervention period to serve as a control, during which time SLNB rate was determined via 194 patients in the target demographic. SLNB rate was again collected during the 12-month intervention period, which involved 193 patients meeting enrollment criteria. Between these periods, the investigators conducted a brief session lasting less than 30 minutes to introduce the surgeons to the rationale and design of the nudge column.
 

How Effective Was the Nudge System?

The intervention reduced the SLNB rate from 46.9% to 23.8%, representing a 49.3% decrease in use of SLNB. Efficacy was further supported by a significant reduction in SLNB according to an interrupted time series model (adjusted odds ratio, 0.26; 95% confidence interval, 0.07 to 0.90; P = .03). Extended follow-up showed that this effect was durable beyond the intervention period, with a 6-month mean reduction in SLNB of 15.6%.

Omission of SLNB led to higher rates of pathological node positivity during the intervention period (15.2% vs 8.8%), with all positive cases staged as pN1. Adjuvant therapy recommendations were similar between groups and driven by genomic testing, not nodal status. The intervention period also saw a decrease in referrals for lymphedema evaluation (3.6% vs. 6.2%).

How Might the Nudge System Be Implemented in Other Practices?

Although the SLNB nudge system was effective in the present study, likelihood of uptake among practices could vary widely, according to Anne M. Wallace, MD, professor of clinical surgery at UC San Diego Health and director of the Moores Comprehensive Breast Health Program.

On a fundamental level, not all centers use Epic software, which could present issues with compatibility, Dr. Wallace said in an interview. More importantly, she added, many institutions already have EHR-based alerts and reminders in place, so it is not always feasible to add a new nudge for every possible clinical scenario.

“Already there are so many little icons that we have to go through now when we close a note,” she said. “That’s why electronic medical records are becoming one of the leading stressors in medicine.”

This presents a more complex challenge, Dr. Wallace said, particularly as potentially practice-changing data are becoming available, and physicians may not have time to learn about them and integrate them into routine practice. She suggested that the present system may be most appropriate for oncologists in solo practice, or in small group practices where it is more challenging to have routine conversations about changing standards of care.

What Are the Risks of Using the Nudge System?

One of those conversations may surround the validity of the recommendation implemented in the present study.

Although the Society of Surgical Oncology recommends against SLNB in the described demographic, other experts, including Dr. Wallace, take a more nuanced view of the decision.

She noted that some patients with a chronological age of 70 may have a lower biological age, casting doubt on the legitimacy of the age threshold, and those near the threshold may wish to make the decision about staging for themselves.

Beyond these concerns, Dr. Wallace described two potential risks involved in forgoing SLNB.

First, there’s the potential for underestimating the tumor’s severity, she said, as this could mean a trip back to the operating room. A tumor initially thought to be low-grade might later be found to be high-grade, necessitating further surgery. Some patients might refuse additional surgery, leaving the more aggressive tumor untreated.

Second, the nudge system could complicate radiation treatment decisions, Dr. Wallace said. Without full nodal status, some radiation oncologists might push for additional radiation therapy, which incurs a greater treatment burden than SNLB.

Avoiding severe skin reactions to antiseizure medications (ASMs) requires assessing patient risk factors and prescribing lower-risk drugs wherever possible, according to authors of a recent review. And if putting higher-risk patients on drugs most associated with human leukocyte antigen (HLA)–related reaction risk before test results are available, authors advised starting at low doses and titrating slowly.

“When someone is having a seizure drug prescribed,” said senior author Ram Mani, MD, MSCE, chief of epilepsy at Rutgers Robert Wood Johnson Medical School in New Brunswick, New Jersey, “it’s often a tense clinical situation because the patient has either had the first few seizures of their life, or they’ve had a worsening in their seizures.”

To help physicians optimize choices, Dr. Mani and colleagues reviewed literature regarding 31 ASMs. Their study was published in Current Treatment Options in Neurology.

Overall, said Dr. Mani, incidence of benign skin reactions such as morbilliform exanthematous eruptions, which account for 95% of cutaneous adverse drug reactions (CADRs), ranges from a few percent up to 15%. “It’s a somewhat common occurrence. Fortunately, the reactions that can lead to morbidity and mortality are fairly rare.”
 

Severe Cutaneous Adverse Reactions

Among the five ASMs approved by the Food and Drug Administration since 2018, cenobamate has sparked the greatest concern. In early clinical development for epilepsy, a fast titration schedule (starting at 50 mg/day and increasing by 50 mg every 2 weeks to at least 200 mg/day) resulted in three cases of drug reaction with eosinophilia and systemic symptoms (DRESS, also called drug-induced hypersensitivity reaction/DIHS), including one fatal case. Based on a phase 3 trial, the drug’s manufacturer now recommends starting at 12.5 mg and titrating more slowly.

DRESS/DIHS appears within 2-6 weeks of drug exposure. Along with malaise, fever, and conjunctivitis, symptoms can include skin eruptions ranging from morbilliform to hemorrhagic and bullous. “Facial edema and early facial rash are classic findings,” the authors added. DRESS also can involve painful lymphadenopathy and potentially life-threatening damage to the liver, heart, and other organs.

Stevens-Johnson syndrome (SJS), which is characterized by detached skin measuring less than 10% of the entire body surface area, typically happens within the first month of drug exposure. Flu-like symptoms can appear 1-3 days before erythematous to dusky macules, commonly on the chest, as well as cutaneous and mucosal erosions. Along with the skin and conjunctiva, SJS can affect the eyes, lungs, liver, bone marrow, and gastrointestinal tract.

When patients present with possible DRESS or SJS, the authors recommended inpatient multidisciplinary care. Having ready access to blood tests can help assess severity and prognosis, Dr. Mani explained. Inpatient evaluation and treatment also may allow faster access to other specialists as needed, and monitoring of potential seizure exacerbation in patients with uncontrolled seizures for whom the drug provided benefit but required abrupt discontinuation.

Often, he added, all hope is not lost for future use of the medication after a minor skin reaction. A case series and literature review of mild lamotrigine-associated CADRs showed that most patients could reintroduce and titrate lamotrigine by waiting at least 4 weeks, beginning at 5 mg/day, and gradually increasing to 25 mg/day.
 

Identifying Those at Risk

With millions of patients being newly prescribed ASMs annually, accurately screening out all people at risk of severe cutaneous adverse reactions based on available genetic information is impossible. The complexity of evolving recommendations for HLA testing makes them hard to remember, Dr. Mani said. “Development and better use of clinical decision support systems can help.”

Accordingly, he starts with a thorough history and physical examination, inquiring about prior skin reactions or hypersensitivity, which are risk factors for future reactions to drugs such as carbamazepine, phenytoin, phenobarbital, oxcarbazepine, lamotrigine, rufinamide, and zonisamide. “Most of the medicines that the HLA tests are being done for are not the initial medicines I typically prescribe for a patient with newly diagnosed epilepsy,” said Dr. Mani. For ASM-naive patients with moderate or high risk of skin hypersensitivity reactions, he usually starts with lacosamide, levetiracetam, or brivaracetam. Additional low-risk drugs he considers in more complex cases include valproate, topiramate, and clobazam.

Only if a patient’s initial ASM causes problems will Dr. Mani consider higher-risk options and order HLA tests for patients belonging to indicated groups — such as testing for HLA-B*15:02 in Asian patients being considered for carbamazepine. About once weekly, he must put a patient on a potentially higher-risk drug before test results are available. If after a thorough risk-benefit discussion, he and the patient agree that the higher-risk drug is warranted, Dr. Mani starts at a lower-than-labeled dose, with a slower titration schedule that typically extends the ramp-up period by 1 week.

Fortunately, Dr. Mani said that, in 20 years of practice, he has seen more misdiagnoses — involving rashes from poison ivy, viral infections, or allergies — than actual ASM-induced reactions. “That’s why the patient, family, and practitioner need to be open-minded about what could be causing the rash.”

Dr. Mani reported no relevant conflicts. The study authors reported no funding sources.

Veterans diagnosed with epilepsy have a significantly higher mortality rate if they experience a traumatic brain injury either before or within 6 months of an epilepsy diagnosis, according to recent research published in Epilepsia.

In a retrospective cohort study, Ali Roghani, PhD, of the division of epidemiology at the University of Utah School of Medicine in Salt Lake City, and colleagues evaluated 938,890 veterans between 2000 and 2019 in the Defense Health Agency and the Veterans Health Administration who served in the US military after the September 11 attacks. Overall, 27,436 veterans met criteria for a diagnosis of epilepsy, 264,890 had received a diagnosis for a traumatic brain injury (TBI), and the remaining patients had neither epilepsy nor TBI.

Among the veterans with no epilepsy, 248,714 veterans had a TBI diagnosis, while in the group of patients with epilepsy, 10,358 veterans experienced a TBI before their epilepsy diagnosis, 1598 were diagnosed with a TBI within 6 months of epilepsy, and 4310 veterans had a TBI 6 months after an epilepsy diagnosis. The researchers assessed all-cause mortality in each group, calculating cumulative mortality rates compared with the group of veterans who had no TBI and no epilepsy diagnosis.

Dr. Roghani and colleagues found a significantly higher mortality rate among veterans who developed epilepsy compared with a control group with neither epilepsy nor TBI (6.26% vs. 1.12%; P < .01), with a majority of veterans in the group who died being White (67.4%) men (89.9%). Compared with veterans who were deceased, nondeceased veterans were significantly more likely to have a history of being deployed (70.7% vs. 64.8%; P < .001), were less likely to be in the army (52.2% vs. 55.0%; P < .001), and were more likely to reach the rank of officer or warrant officer (8.1% vs. 7.6%; P = .014).

There were also significant differences in clinical characteristics between nondeceased and deceased veterans, including a higher rate of substance abuse disorder, smoking history, cardiovascular disease, stroke, transient ischemic attack, cancer, liver disease, kidney disease, or other injury as well as overdose, suicidal ideation, and homelessness. “Most clinical conditions were significantly different between deceased and nondeceased in part due to the large cohort size,” the researchers said.

After performing Cox regression analyses, the researchers found a higher mortality risk in veterans with epilepsy and/or TBIs among those who developed a TBI within 6 months of an epilepsy diagnosis (hazard ratio [HR], 5.02; 95% CI, 4.21-5.99), had a TBI prior to epilepsy (HR, 4.25; 95% CI, 3.89-4.58), had epilepsy alone (HR, 4.00; 95% CI, 3.67-4.36), had a TBI more than 6 months after an epilepsy diagnosis (HR, 2.49; 95% CI, 2.17-2.85), and those who had epilepsy alone (HR, 1.30; 95% CI, 1.25-1.36) compared with veterans who had neither epilepsy nor a TBI.

“The temporal relationship with TBI that occurred within 6 months after epilepsy diagnosis may suggest an increased vulnerability to accidents, severe injuries, or TBI resulting from seizures, potentially elevating mortality risk,” Dr. Roghani and colleagues wrote.

The researchers said the results “raise concerns” about the subgroup of patients who are diagnosed with epilepsy close to experiencing a TBI.

“Our results provide information regarding the temporal relationship between epilepsy and TBI regarding mortality in a cohort of post-9/11 veterans, which highlights the need for enhanced primary prevention, such as more access to health care among people with epilepsy and TBI,” they said. “Given the rising incidence of TBI in both the military and civilian populations, these findings suggest close monitoring might be crucial to develop effective prevention strategies for long-term complications, particularly [post-traumatic epilepsy].”
 

Reevaluating the Treatment of Epilepsy

Juliann Paolicchi, MD, a neurologist and member of the epilepsy team at Northwell Health in New York, who was not involved with the study, said in an interview that TBIs have been studied more closely since the beginning of conflicts in the Middle East, particularly in Iran and Afghanistan, where “newer artillery causes more diffuse traumatic injury to the brain and the body than the effects of more typical weaponry.”

“The temporal relationship with TBI that occurred within 6 months after epilepsy diagnosis may suggest an increased vulnerability to accidents, severe injuries, or TBI resulting from seizures, potentially elevating mortality risk,” Dr. Roghani and colleagues wrote.

The researchers said the results “raise concerns” about the subgroup of patients who are diagnosed with epilepsy close to experiencing a TBI.

“Our results provide information regarding the temporal relationship between epilepsy and TBI regarding mortality in a cohort of post-9/11 veterans, which highlights the need for enhanced primary prevention, such as more access to health care among people with epilepsy and TBI,” they said. “Given the rising incidence of TBI in both the military and civilian populations, these findings suggest close monitoring might be crucial to develop effective prevention strategies for long-term complications, particularly [post-traumatic epilepsy].”
 

Reevaluating the Treatment of Epilepsy

Juliann Paolicchi, MD, a neurologist and member of the epilepsy team at Northwell Health in New York, who was not involved with the study, said in an interview that TBIs have been studied more closely since the beginning of conflicts in the Middle East, particularly in Iran and Afghanistan, where “newer artillery causes more diffuse traumatic injury to the brain and the body than the effects of more typical weaponry.”

Illicit use of the veterinary tranquilizer xylazine continues to spread across the United States. The drug, which is increasingly mixed with fentanyl, often fails to respond to the opioid overdose reversal medication naloxone and can cause severe necrotic lesions.

A report released by Millennium Health, a specialty lab that provides medication monitoring for pain management, drug treatment, and behavioral and substance use disorder treatment centers across the country, showed the number of urine specimens collected and tested at the US drug treatment centers were positive for xylazine in the most recent 6 months.

As previously reported by this news organization, in late 2022, the US Food and Drug Administration (FDA) issued a communication alerting clinicians about the special management required for opioid overdoses tainted with xylazine, which is also known as “tranq” or “tranq dope.”

Subsequently, in early 2023, The White House Office of National Drug Control Policy designated xylazine combined with fentanyl as an emerging threat to the United States.

Both the FDA and the Drug Enforcement Administration have taken steps to try to stop trafficking of the combination. However, despite these efforts, xylazine use has continued to spread.

The Millennium Health Signals report showed that the greatest increase in xylazine use was largely in the western United States. In the first 6 months of 2023, 3% of urine drug tests (UDTs) in Washington, Oregon, California, Hawaii, and Alaska were positive for xylazine. From November 2023 to April 2024, this rose to 8%, a 147% increase. In the Mountain West, xylazine-positive UDTs increased from 2% in 2023 to 4% in 2024, an increase of 94%. In addition to growth in the West, the report showed that xylazine use increased by more than 100% in New England — from 14% in 2023 to 28% in 2024.

Nationally, 16% of all urine specimens were positive for xylazine from late 2023 to April 2024, up slightly from 14% from April to October 2023.

Xylazine use was highest in the East and in the mid-Atlantic United States. Still, positivity rates in the mid-Atlantic dropped from 44% to 33%. The states included in that group were New York, Pennsylvania, Delaware, and New Jersey. East North Central states (Ohio, Michigan, Wisconsin, Indiana, and Illinois) also experienced a decline in positive tests from 32% to 30%.

The South Atlantic states, which include Maryland, Virginia, West Virginia, North and South Carolina, Georgia, and Florida, had a 17% increase in positivity — from 22% to 26%.

From April 2023 to April 2024 state-level UDT positivity rates were 40% in Pennsylvania, 37% in New York, and 35% in Ohio. But rates vary by locality. In Clermont and Hamilton counties in Ohio — both in the Cincinnati area — about 70% of specimens were positive for xylazine.

About one third of specimens in Maryland and South Carolina contained xylazine.

“Because xylazine exposure remains a significant challenge in the East and is a growing concern in the West, clinicians across the US need to be prepared to recognize and address the consequences of xylazine use — like diminished responses to naloxone and severe skin wounds that may lead to amputation — among people who use fentanyl,” Millennium Health Chief Clinical Officer Angela Huskey, PharmD, said in a press release.

The Health Signals Alert analyzed more than 50,000 fentanyl-positive UDT specimens collected between April 12, 2023, and April 11, 2024. Millennium Health researchers analyzed xylazine positivity rates in fentanyl-positive UDT specimens by the US Census Division and state.

Neurologic symptoms of long COVID are vast, common, hard to treat, disabling, and can mimic dozens of other syndromes, with some symptoms as serious as those seen in myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS) and postural orthostatic tachycardia syndrome (POTS).

Now, recent evidence has suggested long COVID is primarily an autonomic nervous system disorder.

Patients with long COVID increasingly complain of extreme fatigue, brain fog, cognitive issues, dizziness, irregular heart rhythms, and high or low blood pressure, all features seen with dysautonomia — dysregulation of the autonomic nervous system.

Their lives may never be the same.

Lindsay S. McAlpine, MD, a specialist in the neurologic sequelae of COVID-19 at the Yale School of Medicine and director of the Yale NeuroCOVID Clinic, New Haven, Connecticut, treats patients who struggle with neurologic symptoms even after disease recovery.

“Some people have the brain fog and the shortness of breath; some have the palpitations and the headaches ... it’s kind of a mix and match,” she said.

Dr. McAlpine’s research has been slowly building up into what could bring about a significant breakthrough in treating some of the most misunderstood and difficult-to-treat symptoms of long COVID.
 

The Effect of Vascular Inflammation on Long COVID

The National Institute of Neurological Disorders and Stroke recently awarded her a 5-year K23 grant to support her ongoing study, “Magnetic Resonance Imaging Biomarkers of Post-COVID-19 Cerebral Microvascular Dysfunction.”

Using advanced MRI techniques to identify microvascular dysfunction biomarkers in the brain, McAlpine hopes to unearth and better understand the pathophysiology behind neurologic issues post-COVID.

Dr. McAlpine said, “What we’re seeing is that there’s a unique signature of vascular inflammation in long COVID that is distinct from acute COVID. And it has to do with endothelial apathy and platelet dysfunction.”

She’s also looking into whether microvascular dysfunction could increase one’s risk for small vessel disease. Her research is quantitatively building an overall pathophysiology piece by piece.

“We’re quantifying cognitive dysfunction and using objective testing ... a very rigorous 3-hour protocol to really identify the patterns of weakness until we find deficits in memory working and declarative memory, deficits in executive functioning, and others. Those are the three pieces that I’m trying to piece together: The MRI, the blood work, and the cognitive testing,” she said.

Ultimately, Dr. McAlpine believes long COVID will eventually be classified as a peripheral autonomic disorder. The damage being wrought to the whole body also damages the brain’s vasculature, and Dr. McAlpine’s MRI techniques probe at this connection.

“Some of my MRI techniques are dependent on the very subtle changes in blood flow to different regions in response to demand. Brain fog has been a key symptom of POTS and ME/CFS. And it’s now a key symptom of long COVID ... what I’m looking at in some of my studies is how and in which parts of the brain are affected by this,” she said.

Dr. McAlpine’s interest in COVID’s effect on our nervous system goes back all the way to the first wave of patients with COVID, where she noticed an unusually high incidence of ischemic stroke.

“We recognized that COVID really has a huge impact on the vessels ... there’s quite a bit of vascular inflammation. In terms of neurology, we were seeing quite a bit of ischemic stroke, which is unusual,” she said.

Patients don’t normally present with stroke while infected with a virus. Seeking answers, she conducted a stroke study in patients with acute COVID and found profound endotheliopathy — damage to key cells in the lining of blood vessels — leading to a cascade of dysfunction and clotting.
 

A Constellation of Neuropsychiatric Symptoms

In early June, Dr. McAlpine gave a presentation of her research at the Demystifying Long COVID North American Conference 2024 in Boston. She’s been hard at work in extrapolating the causes of neuropsychiatric long COVID, a tangled web of symptoms seen in patients with long COVID that range from cognitive dysfunction to headaches, neuropathy, mental health, and the aforementioned dysautonomia.

Amid the sea of neurologic long COVID symptoms, she said “symptoms that are mixing and matching are very similar. So, I wanted to specifically look at a symptom that I could definitely isolate to the brain, and that is brain fog and cognitive dysfunction and impairment.”

In September 2021, the journal Translational Psychiatry published a study titled “Neuropsychiatric manifestations of COVID-19, potential neurotropic mechanisms, and therapeutic interventions.”

Going back all the way to the first cases of COVID in March 2020, the initial symptoms most patients complained of during an acute viral infection were around the respiratory system. Yet delirium, confusion, and neurocognitive disorders were also reported, puzzling experts and inciting a well-founded fear among many.

Even worse, after recovery, these neuropsychiatric symptoms persisted. The study found that coronavirus was able to invade the central nervous system through blood vessels and neuronal retrograde pathways, leading to brain injury and dysfunction of the cardiorespiratory center in the brainstem.

The study concluded by reporting that neuroimaging and neurochemical evidence indicated neuroimmune dysfunction and brain injury in severe patients with COVID-19. Suggested treatments included immunosuppressive therapies, vaccines to target the coronavirus’ spike protein, and pharmacological agents to improve endothelial integrity.

But there was still much that was unknown, and the study’s authors stressed the need for multidisciplinary research going forward.
 

How Immune Dysfunction Plays a Role

Similarly, Dr. McAlpine and her research team are still trying to sift their way through this opaque web to see why long COVID can cause autoimmune flare-ups.

In a study published in April, Dr. McAlpine and others found that small fiber neuropathy (SFN) after COVID is autoimmune-mediated and a dysfunction of the immune system.

Notably, they found that SFN could be a key pathologic finding in long COVID. SFN before the pandemic had been linked to ME/CFS and POTS, and the basic hypothesis revolved around an inflammatory immune response during a viral illness that may lead to immune dysregulation (dysimmunity) and damage to small fiber nerves.

But much still remains to be answered.

“We’ve seen quite a bit of that, but we still haven’t figured it out,” Dr. McAlpine said. “My big question is, how is this autonomic dysfunction related to the immune dysfunction, and how is that related to the vascular inflammation? There’s quite a bit of overlap in individuals with autoimmune disease and those who go on to develop this long COVID,” she added.

Still, a large portion of patients with long COVID don’t show autoimmune dysfunction, and those patients lack common biomarkers for an autoimmune condition.

“When we look at the spinal fluid in those individuals [with multiple sclerosis or a neuroinfectious disease], there’s inflammation going on ... the white blood cell count is elevated, the protein is elevated, the antibodies, the bands are elevated. I’ve been seeing long COVID patients now for 4 years, and their presentation is so distinctly different compared to my individuals that I see my patients with MS, or a neuroinfectious disease,” she said.

The mechanisms behind how all of this is interlaced remain unclear, and there may not be a one-size-fits-all treatment or definite pathogenesis for everyone.

“It’s that intersection of the immune system and the vessel wall ... Next is to figure out what do we treat, what are the targets, all of that, but there’s so many different presentations, and everybody has kind of a unique case,” she said.
 

How Physician Can Treat Common Symptoms Now

Though a cure for symptoms still eludes the scientific community, recent evidence has suggested that a combination of N-acetyl cysteine (NAC) and guanfacine has been successful in easing neurologic symptoms.

In November 2023, Arman Fesharaki-Zadeh, MD, PhD, a Yale Medicine behavioral neurologist and neuropsychiatrist, published a small study in Neuroimmunology Reports with his colleague, Yale neuroscientist Amy Arnsten, PhD. The two researchers showed how among 12 patients given 600 mg NAC daily, along with 1 mg guanfacine (increased to 2 mg after a month if well-tolerated), eight demonstrated improved cognitive abilities.

In patients who stayed on guanfacine + NAC, improved working memory, concentration, and executive functions were seen.

Also, they resumed their normal work schedule. Interruption and inability to work has been a significant factor in the lower quality-of-life long COVID patients experience.

Placebo-controlled trials will be needed going forward, but their small study has established safety and could open up a larger study in the future. For the moment, NAC can be gotten over the counter, and patients could get a prescription off-label from their doctor.

Dr. McAlpine has seen this combination work well for her own patients at Yale’s NeuroCOVID clinic.

Additionally, lifestyle practices such as quitting tobacco, increased exercise, exercising the mind, lowering alcohol intake, and even vitamin D supplementation (1000-2000 IU daily) could prove beneficial in tamping down persistent brain fog.

Vitamin D supports brain and nerve function through its reduction of brain aging biomarkers, regulating genes important for brain function, activating and deactivating enzymes important for neurotransmitter synthesis, and supporting neuronal growth and survival.

Dr. McAlpine’s interest in COVID’s effect on our nervous system goes back all the way to the first wave of patients with COVID, where she noticed an unusually high incidence of ischemic stroke.

“We recognized that COVID really has a huge impact on the vessels ... there’s quite a bit of vascular inflammation. In terms of neurology, we were seeing quite a bit of ischemic stroke, which is unusual,” she said.

Patients don’t normally present with stroke while infected with a virus. Seeking answers, she conducted a stroke study in patients with acute COVID and found profound endotheliopathy — damage to key cells in the lining of blood vessels — leading to a cascade of dysfunction and clotting.
 

A Constellation of Neuropsychiatric Symptoms

In early June, Dr. McAlpine gave a presentation of her research at the Demystifying Long COVID North American Conference 2024 in Boston. She’s been hard at work in extrapolating the causes of neuropsychiatric long COVID, a tangled web of symptoms seen in patients with long COVID that range from cognitive dysfunction to headaches, neuropathy, mental health, and the aforementioned dysautonomia.

Amid the sea of neurologic long COVID symptoms, she said “symptoms that are mixing and matching are very similar. So, I wanted to specifically look at a symptom that I could definitely isolate to the brain, and that is brain fog and cognitive dysfunction and impairment.”

In September 2021, the journal Translational Psychiatry published a study titled “Neuropsychiatric manifestations of COVID-19, potential neurotropic mechanisms, and therapeutic interventions.”

Going back all the way to the first cases of COVID in March 2020, the initial symptoms most patients complained of during an acute viral infection were around the respiratory system. Yet delirium, confusion, and neurocognitive disorders were also reported, puzzling experts and inciting a well-founded fear among many.

Even worse, after recovery, these neuropsychiatric symptoms persisted. The study found that coronavirus was able to invade the central nervous system through blood vessels and neuronal retrograde pathways, leading to brain injury and dysfunction of the cardiorespiratory center in the brainstem.

The study concluded by reporting that neuroimaging and neurochemical evidence indicated neuroimmune dysfunction and brain injury in severe patients with COVID-19. Suggested treatments included immunosuppressive therapies, vaccines to target the coronavirus’ spike protein, and pharmacological agents to improve endothelial integrity.

But there was still much that was unknown, and the study’s authors stressed the need for multidisciplinary research going forward.
 

How Immune Dysfunction Plays a Role

Similarly, Dr. McAlpine and her research team are still trying to sift their way through this opaque web to see why long COVID can cause autoimmune flare-ups.

In a study published in April, Dr. McAlpine and others found that small fiber neuropathy (SFN) after COVID is autoimmune-mediated and a dysfunction of the immune system.

Notably, they found that SFN could be a key pathologic finding in long COVID. SFN before the pandemic had been linked to ME/CFS and POTS, and the basic hypothesis revolved around an inflammatory immune response during a viral illness that may lead to immune dysregulation (dysimmunity) and damage to small fiber nerves.

But much still remains to be answered.

“We’ve seen quite a bit of that, but we still haven’t figured it out,” Dr. McAlpine said. “My big question is, how is this autonomic dysfunction related to the immune dysfunction, and how is that related to the vascular inflammation? There’s quite a bit of overlap in individuals with autoimmune disease and those who go on to develop this long COVID,” she added.

Still, a large portion of patients with long COVID don’t show autoimmune dysfunction, and those patients lack common biomarkers for an autoimmune condition.

“When we look at the spinal fluid in those individuals [with multiple sclerosis or a neuroinfectious disease], there’s inflammation going on ... the white blood cell count is elevated, the protein is elevated, the antibodies, the bands are elevated. I’ve been seeing long COVID patients now for 4 years, and their presentation is so distinctly different compared to my individuals that I see my patients with MS, or a neuroinfectious disease,” she said.

The mechanisms behind how all of this is interlaced remain unclear, and there may not be a one-size-fits-all treatment or definite pathogenesis for everyone.

“It’s that intersection of the immune system and the vessel wall ... Next is to figure out what do we treat, what are the targets, all of that, but there’s so many different presentations, and everybody has kind of a unique case,” she said.
 

How Physician Can Treat Common Symptoms Now

Though a cure for symptoms still eludes the scientific community, recent evidence has suggested that a combination of N-acetyl cysteine (NAC) and guanfacine has been successful in easing neurologic symptoms.

In November 2023, Arman Fesharaki-Zadeh, MD, PhD, a Yale Medicine behavioral neurologist and neuropsychiatrist, published a small study in Neuroimmunology Reports with his colleague, Yale neuroscientist Amy Arnsten, PhD. The two researchers showed how among 12 patients given 600 mg NAC daily, along with 1 mg guanfacine (increased to 2 mg after a month if well-tolerated), eight demonstrated improved cognitive abilities.

In patients who stayed on guanfacine + NAC, improved working memory, concentration, and executive functions were seen.

Also, they resumed their normal work schedule. Interruption and inability to work has been a significant factor in the lower quality-of-life long COVID patients experience.

Placebo-controlled trials will be needed going forward, but their small study has established safety and could open up a larger study in the future. For the moment, NAC can be gotten over the counter, and patients could get a prescription off-label from their doctor.

Dr. McAlpine has seen this combination work well for her own patients at Yale’s NeuroCOVID clinic.

Additionally, lifestyle practices such as quitting tobacco, increased exercise, exercising the mind, lowering alcohol intake, and even vitamin D supplementation (1000-2000 IU daily) could prove beneficial in tamping down persistent brain fog.

Vitamin D supports brain and nerve function through its reduction of brain aging biomarkers, regulating genes important for brain function, activating and deactivating enzymes important for neurotransmitter synthesis, and supporting neuronal growth and survival.

TOPLINE:

A high-fiber diet affects small intestine metabolism, spurring release of the appetite-suppressing gut hormone peptide tyrosine tyrosine (PYY) more than a low-fiber diet, and it does so regardless of the food’s structure, new research revealed.

METHODOLOGY:

• Researchers investigated how low- and high-fiber diets affect the release of the gut hormones PYY and glucagon-like peptide 1 (GLP-1).
• They randomly assigned 10 healthy volunteers to 4 days on one of three diets: High-fiber intact foods, such as peas and carrots; high-fiber foods with disrupted structures (same high-fiber foods, but mashed or blended); or low-fiber processed foods. Volunteers then participated in the remaining two diets in a randomized order, with a washout period of at least a week in which they reverted to their normal diet between each session.
• The diets were energy- and macronutrient-matched, but only the two high-fiber diets were fiber-matched at 46.3-46.7 grams daily, whereas the low-fiber diet contained 12.6 grams of daily fiber.
• The researchers used nasoenteric tubes to sample chyme from the participants’ distal ileum lumina in a morning fasted state and every 60 minutes for 480 minutes postprandially on days 3 and 4 and confirmed their findings using ileal organoids. Participants reported their postprandial hunger using a visual analog scale.

TAKEAWAY:

• Both high-fiber diets increased PYY release — but not GLP-1 release — compared with a low-fiber diet during the 0-240-minute postprandial period, when the food was mainly in the small intestine.
• At 120 minutes, both high-fiber diets increased PYY compared with the low-fiber diet, a finding that counteracted the researchers’ hypothesis that intact food structures would stimulate PYY to a larger extent than disrupted food structures. Additionally, participants reported less hunger at 120 minutes with the high-fiber diets, compared with the low-fiber diet.
• High-fiber diets also increased ileal stachyose, and the disrupted high-fiber diet increased certain ileal amino acids.
• Treating the ileal organoids with ileal fluids or an amino acid and stachyose mixture stimulated PYY expression similarly to blood PYY expression, confirming the role of ileal metabolites in the release of PYY.

IN PRACTICE:

“High-fiber diets, regardless of their food structure, increased PYY release through alterations in the ileal metabolic profile,” the authors wrote. “Ileal molecules, which are shaped by dietary intake, were shown to play a role in PYY release, which could be used to design diets to promote satiety.”

SOURCE:

The study, led by Aygul Dagbasi, PhD, Imperial College London, England, was published online in Science Translational Medicine

LIMITATIONS:

The study had several limitations, including the small number of participants. The crossover design limited the influence of covariates on the study outcomes. Gastric emptying and gut transit rates differed widely; therefore, food that may have reached and affected the ileum prior to the first postprandial sample point at 60 minutes was not captured. The authors had access to a limited number of organoids, which restricted the number of experiments they could do. Although organoids are useful tools in vitro, they have limitations, the researchers noted.

DISCLOSURES:

The research was funded by the Biotechnology and Biological Sciences Research Council (BBSRC), Nestle Research, and Sosei Heptares. The Section for Nutrition at Imperial College London is funded by grants from the UK Medical Research Council, BBSRC, National Institute for Health and Care Research, and UKRI Innovate UK and is supported by the National Institute for Health and Care Research Imperial Biomedical Research Centre Funding Scheme. The study was funded by UKRI BBSRC to the principal investigator. The lipid analysis was funded by a British Nutrition Foundation Drummond Early Career Scientist Award.

Three coauthors disclose that they are directors of Melico Sciences, and several coauthors have relationships with industry outside of the submitted work.

An estimated two million people in England and Scotland were experiencing symptoms of long COVID as of March 2024, according to the Office for National Statistics. Of these, 1.5 million said the condition was adversely affecting their day-to-day activities.

As more research emerges about long COVID, some experts are noticing that its trigger factors, symptoms, and causative mechanisms overlap with myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS).

ME/CFS is characterized by severe fatigue that does not improve with rest, in addition to pain and cognitive problems. One in four patients are bed- or house-bound with severe forms of the condition, sometimes experiencing atypical seizures, and speech and swallowing difficulties.

Despite affecting around 250,000 people in the UK and around 2 million people in the European Union (EU), it is a relatively poorly funded disease research area. Increased research into long COVID is thus providing a much-needed boost to ME/CFS research.

“What we already know about the possible causation of ME/CFS is helping research into the causes of long COVID. At the same time, research into long COVID is opening up new avenues of research that may also be relevant to ME/CFS. It is becoming a two-way process,” Dr. Charles Shepherd, honorary medical adviser to the UK-based ME Association, told this news organization.

While funding remains an issue, promising research is currently underway in the UK to improve diagnosis, treatment, and understanding of the pathology of ME/CFS.
 

Viral Reactivation

Dr. David Newton is research director at ME Research UK. “Viral infection is commonly reported as a trigger for [ME/CFS, meaning that the disease] may be caused by reactivation of latent viruses, including human herpes viruses and enteroviruses,” he said.

Herpes viruses can lie dormant in their host’s immune system for long periods of time. They can be reactivated by factors including infections, stress, and a weakened immune system, and may cause temporary symptoms or persistent disease.

A 2021 pilot study found that people with ME/CFS have a higher concentration of human herpesvirus 6B (HHV-6B) DNA in their saliva, and that concentration correlates with symptom severity. HHV-6B is a common virus typically contracted during infancy and childhood.

A continuation of this research is now underway at Brunel University to improve understanding of HHV-6B’s role in the onset and progression of ME/CFS, and to support the development of diagnostic and prognostic markers, as well as therapeutics such as antiviral therapies.
 

Mitochondrial Dysfunction

Dr. Shepherd explained that there is now sound evidence demonstrating that biochemical abnormalities in ME/CFS affect how mitochondria produce energy after physical exertion. Research is thus underway to see if treating mitochondrial dysfunction improves ME/CFS symptoms.

A phase 2a placebo-controlled clinical trial from 2023 found that AXA1125, a drug that works by modulating energy metabolism, significantly improved symptoms of fatigue in patients with fatigue-dominant long COVID, although it did not improve mitochondrial respiration.

“[The findings suggest] that improving mitochondrial health may be one way to restore normal functioning among people with long COVID, and by extension CFS,” study author Betty Raman, associate professor of cardiovascular medicine at the University of Oxford, told this news organization. She noted, however, that plans for a phase III trial have stalled due to insufficient funding.

Meanwhile, researchers from the Quadram Institute in Norwich and the University of East Anglia are conducting a pilot study to see if red light therapy can relieve symptoms of ME/CFS. Red light can be absorbed by mitochondria and is used to boost energy production. The trial will monitor patients remotely from their homes and will assess cognitive function and physical activity levels.
 

Gut Dysbiosis

Many studies have found that people with ME/CFS have altered gut microbiota, which suggests that changes in gut bacteria may contribute to the condition. Researchers at the Quadram Institute will thus conduct a clinical trial called RESTORE-ME to see whether fecal microbiota transplants (FMT) can treat the condition.

Rik Haagmans is a research scientist and PhD candidate at the Quadram Institute. He told this news organization: “Our FMT studies, if effective, could provide a longer lasting or even permanent relief of ME/CFS, as restoring the gut microbial composition wouldn’t require continuous medication,” he said.
 

Biobank and Biomarkers

Europe’s first ME/CFS-specific biobank is in the UK and is called UKMEB. It now has more than 30,000 blood samples from patients with ME/CFS, multiple sclerosis, and healthy controls. Uniquely, it includes samples from people with ME/CFS who are house- and bed-bound. Caroline Kingdon, RN, MSc, a research fellow and biobank lead at the London School of Hygiene and Tropical Medicine, told this news organization that samples and data from the UKMEB have been provided to research groups all over the world and have contributed to widely cited literature.

One group making use of these samples is led by Fatima Labeed, PhD, senior lecturer in human biology at the University of Surrey. Dr. Labeed and her team are developing a diagnostic test for ME/CFS based on electrical properties in white blood cells.

“To date, studies of ME/CFS have focused on the biochemical behavior of cells: the amount and type of proteins that cells use. We have taken a different approach, studying the electrical properties,” she explained to this news organization.

Her research builds on initial observations from 2019 that found differences in the electrical impedance of white blood cells between people with ME/CFS and controls. While the biological implications remain unknown, the findings may represent a biomarker for the condition.

Using blood samples from the UKMEB, the researchers are now investigating this potential biomarker with improved techniques and a larger patient cohort, including those with mild/moderate and severe forms of ME/CFS. So far, they have received more than 100 blood samples and have analyzed the electrical properties of 42.

“Based on the results we have so far, we are very close to having a biomarker for diagnosis. Our results so far show a high degree of accuracy and are able to distinguish between ME/CFS and other diseases,” said Dr. Labeed.
 

Genetic Test

Another promising avenue for diagnostics comes from a research team at the University of Edinburgh led by Professor Chris Ponting at the university’s Institute of Genetics and Cancer. They are currently working on DecodeMe, a large genetic study of ME using data from more than 26,000 people.

“We are studying blood-based biomarkers that distinguish people with ME from population controls. We’ve found a large number — including some found previously in other studies — and are writing these results up for publication,” said Ponting. The results should be published in early 2025.
 

The Future

While research into ME/CFS has picked up pace in recent years, funding remains a key bottleneck.

“Over the last 10 years, only £8.05m has been spent on ME research,” Sonya Chowdhury, chief executive of UK charity Action for ME told this news organization. She believes this amount is not equitably comparable to research funding allocated to other diseases.

In 2022, the UK government announced its intention to develop a cross-government interim delivery plan on ME/CFS for England, however publication of the final plan has been delayed numerous times.

Dr. Shepherd agreed that increased funding is crucial for progress to be made. He said the biggest help to ME/CFS research would be to end the disparity in government research funding for the disease, and match what is given for many other disabling long-term conditions.

“It’s not fair to continue to rely on the charity sector to fund almost all of the biomedical research into ME/CFS here in the UK,” he said.

Dr. David Newton is research director at ME Research UK. “Viral infection is commonly reported as a trigger for [ME/CFS, meaning that the disease] may be caused by reactivation of latent viruses, including human herpes viruses and enteroviruses,” he said.

Herpes viruses can lie dormant in their host’s immune system for long periods of time. They can be reactivated by factors including infections, stress, and a weakened immune system, and may cause temporary symptoms or persistent disease.

A 2021 pilot study found that people with ME/CFS have a higher concentration of human herpesvirus 6B (HHV-6B) DNA in their saliva, and that concentration correlates with symptom severity. HHV-6B is a common virus typically contracted during infancy and childhood.

A continuation of this research is now underway at Brunel University to improve understanding of HHV-6B’s role in the onset and progression of ME/CFS, and to support the development of diagnostic and prognostic markers, as well as therapeutics such as antiviral therapies.
 

Mitochondrial Dysfunction

Dr. Shepherd explained that there is now sound evidence demonstrating that biochemical abnormalities in ME/CFS affect how mitochondria produce energy after physical exertion. Research is thus underway to see if treating mitochondrial dysfunction improves ME/CFS symptoms.

A phase 2a placebo-controlled clinical trial from 2023 found that AXA1125, a drug that works by modulating energy metabolism, significantly improved symptoms of fatigue in patients with fatigue-dominant long COVID, although it did not improve mitochondrial respiration.

“[The findings suggest] that improving mitochondrial health may be one way to restore normal functioning among people with long COVID, and by extension CFS,” study author Betty Raman, associate professor of cardiovascular medicine at the University of Oxford, told this news organization. She noted, however, that plans for a phase III trial have stalled due to insufficient funding.

Meanwhile, researchers from the Quadram Institute in Norwich and the University of East Anglia are conducting a pilot study to see if red light therapy can relieve symptoms of ME/CFS. Red light can be absorbed by mitochondria and is used to boost energy production. The trial will monitor patients remotely from their homes and will assess cognitive function and physical activity levels.
 

Gut Dysbiosis

Many studies have found that people with ME/CFS have altered gut microbiota, which suggests that changes in gut bacteria may contribute to the condition. Researchers at the Quadram Institute will thus conduct a clinical trial called RESTORE-ME to see whether fecal microbiota transplants (FMT) can treat the condition.

Rik Haagmans is a research scientist and PhD candidate at the Quadram Institute. He told this news organization: “Our FMT studies, if effective, could provide a longer lasting or even permanent relief of ME/CFS, as restoring the gut microbial composition wouldn’t require continuous medication,” he said.
 

Biobank and Biomarkers

Europe’s first ME/CFS-specific biobank is in the UK and is called UKMEB. It now has more than 30,000 blood samples from patients with ME/CFS, multiple sclerosis, and healthy controls. Uniquely, it includes samples from people with ME/CFS who are house- and bed-bound. Caroline Kingdon, RN, MSc, a research fellow and biobank lead at the London School of Hygiene and Tropical Medicine, told this news organization that samples and data from the UKMEB have been provided to research groups all over the world and have contributed to widely cited literature.

One group making use of these samples is led by Fatima Labeed, PhD, senior lecturer in human biology at the University of Surrey. Dr. Labeed and her team are developing a diagnostic test for ME/CFS based on electrical properties in white blood cells.

“To date, studies of ME/CFS have focused on the biochemical behavior of cells: the amount and type of proteins that cells use. We have taken a different approach, studying the electrical properties,” she explained to this news organization.

Her research builds on initial observations from 2019 that found differences in the electrical impedance of white blood cells between people with ME/CFS and controls. While the biological implications remain unknown, the findings may represent a biomarker for the condition.

Using blood samples from the UKMEB, the researchers are now investigating this potential biomarker with improved techniques and a larger patient cohort, including those with mild/moderate and severe forms of ME/CFS. So far, they have received more than 100 blood samples and have analyzed the electrical properties of 42.

“Based on the results we have so far, we are very close to having a biomarker for diagnosis. Our results so far show a high degree of accuracy and are able to distinguish between ME/CFS and other diseases,” said Dr. Labeed.
 

Genetic Test

Another promising avenue for diagnostics comes from a research team at the University of Edinburgh led by Professor Chris Ponting at the university’s Institute of Genetics and Cancer. They are currently working on DecodeMe, a large genetic study of ME using data from more than 26,000 people.

“We are studying blood-based biomarkers that distinguish people with ME from population controls. We’ve found a large number — including some found previously in other studies — and are writing these results up for publication,” said Ponting. The results should be published in early 2025.
 

The Future

While research into ME/CFS has picked up pace in recent years, funding remains a key bottleneck.

“Over the last 10 years, only £8.05m has been spent on ME research,” Sonya Chowdhury, chief executive of UK charity Action for ME told this news organization. She believes this amount is not equitably comparable to research funding allocated to other diseases.

In 2022, the UK government announced its intention to develop a cross-government interim delivery plan on ME/CFS for England, however publication of the final plan has been delayed numerous times.

Dr. Shepherd agreed that increased funding is crucial for progress to be made. He said the biggest help to ME/CFS research would be to end the disparity in government research funding for the disease, and match what is given for many other disabling long-term conditions.

“It’s not fair to continue to rely on the charity sector to fund almost all of the biomedical research into ME/CFS here in the UK,” he said.

TOPLINE:

Long-term gender-affirming hormone treatment with testosterone increases the risk for metabolic syndromes in transmasculine individuals, whereas transfeminine individuals receiving estradiol have a lower risk.

METHODOLOGY:

• Many transgender individuals receive exogenous sex hormone therapy to reduce gender dysphoria and improve quality of life. These treatments, however, may influence the development of metabolic syndrome.
• This retrospective, longitudinal cohort study investigated the association between gender-affirming hormone treatment and metabolic syndrome scores in transfeminine and transmasculine individuals compared with cisgender men and women not receiving the treatment.
• Overall, 645 transgender participants (mean age at index date, 41.3 years; 494 transfeminine and 151 transmasculine) were matched with 645 cisgender participants (280 women and 365 men) from the Veterans Health Administration.
• Metabolic syndrome scores were calculated based on blood pressure; body mass index (BMI); and levels of high-density lipoprotein (HDL) cholesterol, triglycerides, and blood glucose.
• Changes in metabolic syndrome scores before and after hormonal transition were compared among transgender and cisgender individuals for the corresponding dates.

TAKEAWAY:

• After hormonal transition, all measured metabolic syndrome components significantly worsened in the transmasculine group (P < .05 for all).
• In contrast, the systolic blood pressure and triglyceride levels decreased, HDL cholesterol levels increased, and BMI showed no significant change in the transfeminine group after hormonal transition.
• The increase in metabolic syndrome scores after vs before the date of hormonal transition was the highest for transmasculine individuals (298.0%; P < .001), followed by cisgender women (108.3%; P < .001), cisgender men (49.3%; P = .02), and transfeminine individuals (3.0%; P = .77).

IN PRACTICE:

“This is relevant for the management of metabolic syndrome risk factors in cisgender and transgender individuals and to potentially predict the risk of atherosclerotic cardiovascular disease, type 2 diabetes, systolic hypertension, insulin resistance, and nonalcoholic fatty liver disease,” the authors wrote.

SOURCE:

Leila Hashemi, MD, MS, of the Department of General Internal Medicine, David Geffen School of Medicine, University of California, Los Angeles, led this study, which was published online in JAMA Network Open.

LIMITATIONS:

Causal inferences could not be drawn because of the study’s observational nature. The transmasculine and cisgender female groups were limited in size, and military veterans have special circumstances not representative of the general population. Minority stress among the transgender veterans was also not considered, which may have affected the health and well-being outcomes.

DISCLOSURES:

This study was supported by the National Institutes of Health and Office of Research on Women’s Health grants. One author received grants from the National Institutes of Health.

Patients starting first-line endocrine and CDK4/6 inhibition for advanced breast cancer show minimal additional cognitive decline beyond what they had already experienced from their neoadjuvant and adjuvant treatments, according to new results of the SONIA trial.

“Patients who are diagnosed with advanced breast cancer and start their first-line treatment already show cognitive impairments due to their previous treatments. And luckily, our results show that during first-line treatment for advanced breast cancer with endocrine therapy, with or without a CDK4/6 inhibitor, further cognitive decline is minimal,” lead investigator Maryse Luijendijk, said during her presentation at the annual meeting of the American Society of Clinical Oncology (ASCO).

“It is well known that cancer patients can experience cognitive problems, such as memory loss, problems with concentration or with planning, during or following their treatment,” explained Ms. Luijendijk, a PhD candidate in the department of Psychosocial Research and Epidemiology at the Netherlands Cancer Institute, in Amsterdam. “Much is known about the effects of chemotherapy or irradiation to the brain, but evidence into endocrine therapy is scarce, which is surprising because cognitive effects are biologically plausible.

“We know that estrogen plays an important role in neuronal functioning and that certain types of endocrine therapies are able to cross the blood-brain barrier, where they may interact with estrogen receptors distributed widely throughout the brain … We know that CDK4/6 inhibitors may either negatively affect cognitive function by increased fatigue due to cytokine release or by interrupting the cell cycle of healthy cells, or positively, as they have been associated with reduced inflammation and remyelination.”

Initial results of the SONIA trial, reported at ASCO last year, examined overall and progression-free survival in patients with HR-positive, HER2-negative metastatic breast cancer and no prior treatment for advanced disease. Findings for those who were randomized to treatment with nonsteroidal aromatase inhibition either with or without the addition of CDK4/6 inhibitors showed no between-group differences, explained Ms. Luijendijk.

The new results, described as being from the SONIA-EfFECT (Evaluation of cognitive functioning in patients with metastatic breast cancer treated with endocrine or combined therapy) trial, were based on the authors investigating cognitive functioning in the same cohort used in the SONIA trial plus a control group.

In SONIA-EfFECT, patients who participated in SONIA were asked to identify a female relative or friend without cancer to serve as a cancer-free control. Members of the 130-patient control group were matched for age, education, and computer use.

Participants in the SONIA trial and control group were asked to complete the Amsterdam Cognition Scan, an online neuropsychological test battery at baseline and again after 9 months of treatment. Of those patients from SONIA, 130 had received first-line treatment with aromatase inhibitors with CDK4/6 inhibition (Arm A) and 130 had received aromatase inhibitors without CDK4/6 inhibition (Arm B).

Baseline assessments for SONIA-EfFECT were completed for 260 patients from SONIA and the full 130-person control group. Follow-up assessments were completed for 119 members of the control group and 199 patients from the original SONIA trial (108 from Arm A, and 91 from Arm B). Patients from SONIA who switched to second-line treatment within 9 months were not retested.

Patients in both SONIA arms performed significantly worse than the controls on the domains of verbal memory, working memory, processing speed, executive function, and motor function. In both patient arms and the controls, standardized regression-based change scores showed limited decline in cognitive function over the 9-month interval. Minimal differences in cognitive change were observed between the patients treated with and without CDK4/6 inhibitors, and between patients and the controls, according to the abstract for SONIA-EfFECT, published in the program for the annual meeting of ASCO.

“At baseline, patients show worse cognitive function across all domains compared to the controls. And as expected, there were no differences between the two treatment arms,” Ms. Luijendijk explained. After 9 months of treatment, the testing showed limited further decline among patients, “and even some improvement on some tests,” with minimal differences between treatment arms “implying that cognitive function does not need to be an aspect when deciding on treatment.”

Ms. Luijendijk reported no relevant disclosures.
