An emerging variant of COVID-19 called BA.2.86 that caused alarm in the summer of 2023 has landed on the Center for Disease Control and Prevention’s radar again.

The variant accounted for nearly 9% of cases during the 2-week period ending Nov. 25, up from 3% during the previous 2 weeks, according to data published Nov. 27 by the CDC. The estimates are not exact, and the CDC indicated the actual percentage of cases may range from 5% to 15%.

The CDC took the unusual step of publishing a specific statement about the rise in BA.2.86 cases. The variant drew worldwide attention during the summer because of how different its makeup is, compared with other prominent variants of the virus that causes COVID-19, raising the potential for the new variant to be more capable of causing infection. But after a flurry of interest in BA.2.86, it didn’t end up being as widespread as expected, so for months it wasn’t listed as a standalone variant on the CDC’s variant tracker list.

“At this time, BA.2.86 does not appear to be driving increases in infections or hospitalizations in the United States,” the CDC wrote in its advisory. “It is not possible at this time to know whether BA.2.86 infection produces different symptoms from other variants. In general, symptoms of COVID-19 tend to be similar across variants. The types of symptoms and how severe they are usually depend more on a person’s immunity than which variant causes the infection.”

BA.2.86 is now the third-most prominent variant circulating the United States, behind HV.1 and EG.5, which combined account for about 45% of all U.S. COVID-19 cases. All three are from the Omicron lineage of the virus.

About 8% of all COVID tests reported to the CDC were positive for the week ending Nov. 18, which is a decline, compared with recent weeks. But indicators for severe cases of the illness have ticked up lately, including rises among ED visits for COVID, hospitalizations, and deaths.

In 2022, two colleagues from Johns Hopkins University, Baltimore, Bhuchitra Singh, MD, MPH, MS, MBA, and James Segars Jr., MD, reviewed the available literature to evaluate the effectiveness of newer minimally invasive therapies in reducing bleeding and improving the quality of life and control of symptoms linked to uterine fibroids. 

Their goal, according to Dr. Segars, a professor of obstetrics and gynecology and director of the division of women’s health research at Johns Hopkins, was to help guide clinicians and patients in making decisions about the use of the newer therapies, including radiofrequency ablation and ultrasound-guided removal of lesions. 

But he and Dr. Singh, the director of clinical research at the Howard W. and Georgeanna Seegar Jones Laboratory of Reproductive Sciences and Women’s Health Research, were surprised by their findings. “The outcomes were relatively the same,” Dr. Segars said. “All of the modalities lead to significant reduction in bleeding and other fibroid-related symptoms.” 

The data on long-term complications and risk for recurrence are sparse for some of the newer approaches, and not enough high-quality long-term studies have been conducted for the Food and Drug Administration to approve them as fertility-sparing treatments.

But perhaps, the biggest challenge now is to ensure that women can take advantage of these newer therapies, with large gaps in both the diagnosis of fibroids and geographic access to minimally invasive treatments.
 

A widespread condition widely underdiagnosed 

Uterine fibroids occur in most women (the incidence rises with age) and can be found in up to 70% of women by the time they reach menopause. Risk factors include family history, increasing interval since last birth, hypertension, and obesity. Increasing parity and use of oral contraceptives are protective.

But as many as 50% of cases go undiagnosed, and one reason for this is the failure of clinicians to dig deeply enough into women’s menstrual histories to diagnose fibroids. 

“The most common cause of anemia is heavy menstrual bleeding,” said Shannon Laughlin-Tommaso, MD, MPH, a professor of obstetrics and gynecology at Mayo Clinic in Rochester, Minn. She frequently sees patients who have already undergone colonoscopy to work-up the source of their anemia before anyone suspects that fibroids are the culprit. 

“When women tell us about their periods, what they’ve been told is normal [bleeding] – or what they’ve always had and considered normal – is actually kind of on the heavier spectrum,” she said. 

Ideally, treatment for uterine fibroids would fix abnormally prolonged or heavy menstrual bleeding, relieve pain, and ameliorate symptoms associated with an enlarged uterus, such as pelvic pressure, urinary frequency, and constipation. And the fibroids would never recur.

By those measures, hysterectomy fits the bill: Success rates in relieving symptoms are high, and the risk for recurrence is zero. But the procedure carries significant drawbacks: short-term complications of surgery, including infection, bleeding, and injury to the bowels and bladder along with potential long-term risks for cardiovascular disease, cancer, ovarian failure and premature menopause, depression, and decline in cognitive function. Those factors loom even larger for women who still hope to have children. 

For that reason, the American College of Obstetricians and Gynecologists recommends myomectomy, or surgical removal of individual fibroids, for women who desire uterine preservation or future pregnancy. And the literature here is solid, according to Dr. Singh, who found that 95% of myomectomy patients achieved control of their bleeding symptoms, whether it was via laparoscopy, hysteroscopy, or laparotomy. Up to 40% of women may develop new fibroids, or leiomyomas, within 3 years, although only 12.2% required a second surgery up to after 5 years. 

But myomectomy is invasive, requiring general anesthesia, incisions in the uterus, and stitches to close the organ. 

Newer techniques have emerged that can effectively treat symptoms of fibroids without requiring surgery. Uterine artery embolization (UAE), which involves passing a catheter into the femoral artery, or laparoscopic uterine artery occlusion can be used to cut off the blood supply of the fibroid. Other techniques, including focused ultrasound surgery and radiofrequency ablation (RFA), use various forms of energy to heat and ablate fibroids. The latter two can be performed in outpatient settings and often without general anesthesia.

Approved for use in 1994, UAE has the most data available, with reduction in the volume of fibroids and uterine tissue lasting up to 5 years, and rates of reintervention of 19%-38% between 2 and 5 years after the procedure. Dr. Singh’s review found that 79%-98.5% of recipients of the procedure reported declines in bleeding that persisted for several years, which is comparable to myomectomy. Quality of life and pain scores also showed good improvement, with follow-up in the different studies ranging from 12 months to over 5 years, the analysis showed.

UAE does have its drawbacks. In rare cases, embolization can deprive the entire uterus and ovaries of blood, which can cause ovarian dysfunction and potentially result in premature menopause, although this outcome is most common in women who are older than 45 years. The procedure can often also be painful enough that overnight hospitalization is required.

Focused ultrasound surgeries, which include magnetic resonance–guided focused ultrasound surgery (MRgFUS) and high-intensity focused ultrasound (HIFU), were approved by the FDA in 2004. Focused ultrasound waves pass through the abdominal wall and produce significant heating, causing a burn that destroys the targeted tissue without damaging surrounding tissue. As with UAE, improvements in fibroid-associated bleeding and measures of quality of life were similar to those after myomectomy up to 3 years later.

But Dr. Singh noted that both focused ultrasound and RFA can damage the skin or internal organs. “[As] always with the thermal interventions, there is the probability of skin as well as internal organs that might get the thermal energy if it’s not focused correctly on to the fibroid itself,” he said. In addition, MRgFUS is not an option for women who are not good candidates to undergo an MRI, such as those with claustrophobia or pacemakers.

Also, with focus ultrasound and RFA, “we do worry about that fibroid getting blood flow back,” which can lead to recurrence of heavy menstrual bleeding, Dr. Laughlin-Tommaso noted. 

Although data on RFA are limited to 12 months of follow-up, most women reported meaningful reductions in bleeding symptoms. Longer follow-up has been reported for bleeding symptoms after MRgFUS, with similar results up to 3 years later. 

For Leslie Hansen-Lindner, MD, chief of obstetrics and gynecology at Atrium Health in Charlotte, N.C., choosing the right procedure starts with a patient-centered conversation weighing the pros and cons of the options and the woman’s goals. 

“Is their goal to reduce the size and impact of their fibroid, bleed less, and have a better quality of life on their period?” Dr. Hansen-Lindner said. “Or is their goal to have the entire fibroid removed?” 

If the former, an RFA is appealing to many women. If the latter, laparoscopic or mini-laparotomy myomectomy might be a better choice. Although fewer than 10% of patients require surgical reintervention at 3 years of follow-up for RFA, myomectomy has more consistent long-term evidence showing that fewer women require re-intervention and preserve their fertility, she added. 

Age also plays a role in the decision: The closer a woman is to menopause, the less likely she is to experience a recurrence, so a less-invasive procedure is preferable. But for younger women hoping to become pregnant, the lower risk for recurrence and good prognosis for future fertility might sway the choice toward myomectomy.

The first laparoscopic RFA procedures were approved for uterine fibroids in 2012. Dr. Hansen-Lindner is a proponent of transcervical fibroid ablation (TFA), a newer RFA procedure that the FDA approved in 2018. Performed through the cervix, TFA requires no incisions and can generally be done without general anesthesia. Eligible candidates would be any woman with symptomatic fibroids, such as heavy menstrual bleeding, pain, or bulk symptoms. The contraindications are few.

“It’s going to come down to size and location of fibroids, and whether or not they would be accessible by the TFA,” Dr. Hansen-Lindner said. “I have to make sure that there isn’t a fibroid blocking their cervix and that the fibroids are accessible with this device.” 

TFA also is not suitable for removing most submucosal lesions, which typically must be removed by hysteroscopic myomectomy. Dr. Hansen-Lindner said that she often uses TFA in conjunction with hysteroscopic myomectomy for this scenario. Although data on pregnancy after RFA (including TFA), MRgFUS, and HIFU are lacking, Gynesonics, the manufacturer of the Sonata System (the device that delivers radiofrequency energy to shrink the fibroid) has documented 79 pregnancies among the 2,200 women who have undergone TFA in the United States since 2018.
 

Disparities hampering care

Uterine fibroids are a particular problem for Black women, whose symptoms are more likely to be ignored by clinicians, according to Jodie Katon, PhD, a core investigator at the Veterans Affairs Greater Los Angeles Center for the Study of Healthcare Innovation, Implementation and Policy. Dr. Katon cited studies in which Black women interviewed about their experiences reported a consistent theme: Clinicians dismissed their symptoms, told them these were nothing to worry about, and advised them to lose weight. Those interactions not only delayed diagnosis among Black women but also led many of them to mistrust clinicians and avoid the health care system altogether.

The failure of clinicians to take their complaints seriously is just one of the disparities affecting Black women. In reviewing the literature, Dr. Laughlin-Tommaso, who also serves as the associate dean for Education Diversity, Equity, and Inclusion at the Mayo Clinic, found that African American women experience two to three times the risk for fibroids, compared with White women, as well as earlier onset and more severe disease, as measured by number and size of the lesions. 

According to Dr. Katon, the etiology of fibroids is still poorly understood. “What we do know is that Black women are disproportionately exposed to a variety of factors that we have shown through observational studies are associated with increased risk of development of uterine fibroids.” 

The list includes factors like stress; interpersonal racism; early age at menarche; various indicators of poor diets, such as vitamin D deficiency; the use of certain beauty products, specifically hair straighteners; as well as exposure to air pollution and other environmental toxins.

Laughlin-Tommaso also pointed to historical disparities in management, citing a doubled risk for hysterectomy for Black women in a study published in 2007 despite survey data suggesting that Black women report being more interested in uterine-preserving therapies rather than a hysterectomy.
 

Breaking down barriers of access to new treatments

Dr. Laughlin-Tommaso looked at more recent trends in the management of fibroids using data from the multicenter COMPARE-UF study, which enrolled women between 2015 and 2020 undergoing fibroid treatment into a longitudinal registry to track their outcomes. She found that Black women underwent hysterectomies at a lower rate than did White women and were instead more likely to undergo myomectomy or UAE. 

Some of the change may reflect lack of approved minimally invasive procedures before 2000. “But now that we have expanded options, I think most women are opting not to have a hysterectomy,” Dr. Laughlin-Tommaso said.

Dr. Katon has research funding from the VA to look more closely at racial disparities in the treatment of fibroids. In a study published in April 2023, she reported some surprising trends. 

During the period from 2010 to 2018, she found that Black veterans diagnosed with fibroids were less likely than White veterans were to receive treatment, regardless of their age or the severity of their symptoms. This finding held even among women with anemia, which should have been a clear indication for treatment.

But, as in the COMPARE-UF study, the subset of Black veterans who received an interventional treatment were less likely than their White peers were to undergo hysterectomy in favor of a fertility-sparing treatment as their initial procedure. Dr. Katon called it a “welcome but unexpected finding.” 

But another significant barrier remains: The two newest types of procedures, RFA and guided focused ultrasound, are not commonly performed outside of tertiary care facilities. However, studies have found that all these procedures are cost effective (studies for myomectomy, UAE, MRgFUS, and TFA). The implementation of a category 1 billing code for laparoscopic RFA in 2017 has led more insurance companies to cover the service, and a category 1 code will be available for TFA effective January 2024. 

Although RFA does require investment in specialized equipment, which limits facilities from offering the procedure, any gynecologist who routinely performs hysteroscopy can easily learn to do TFA. And the VA, which is committed to eliminating disparities in women’s health, established a 2-year advanced fellowship in minimally invasive gynecologic surgery in 2022 to help expand their capacity to offer these procedures. 

The VA has been rapidly expanding their gynecology services, and Katon said that she is confident that ultrasound-guided procedures and RFA will become more available within the system. “I would say we’re keeping pace. And in some ways, you know, as a national system we may be positioned to actually outpace the rest of the U.S.”

Dr. Segars reported prior research funding for clinical trials from BioSpecifics Technologies, Bayer, Allergan, AbbVie, and ObsEva and currently receives funding from Myovant Sciences. Dr. Hansen-Lindner reported personal fees from Gynesonics. Dr. Singh, Dr. Laughlin-Tommaso, and Dr. Katon reported no financial conflicts of interest.

The data on long-term complications and risk for recurrence are sparse for some of the newer approaches, and not enough high-quality long-term studies have been conducted for the Food and Drug Administration to approve them as fertility-sparing treatments.

But perhaps, the biggest challenge now is to ensure that women can take advantage of these newer therapies, with large gaps in both the diagnosis of fibroids and geographic access to minimally invasive treatments.
 

A widespread condition widely underdiagnosed 

Uterine fibroids occur in most women (the incidence rises with age) and can be found in up to 70% of women by the time they reach menopause. Risk factors include family history, increasing interval since last birth, hypertension, and obesity. Increasing parity and use of oral contraceptives are protective.

But as many as 50% of cases go undiagnosed, and one reason for this is the failure of clinicians to dig deeply enough into women’s menstrual histories to diagnose fibroids. 

“The most common cause of anemia is heavy menstrual bleeding,” said Shannon Laughlin-Tommaso, MD, MPH, a professor of obstetrics and gynecology at Mayo Clinic in Rochester, Minn. She frequently sees patients who have already undergone colonoscopy to work-up the source of their anemia before anyone suspects that fibroids are the culprit. 

“When women tell us about their periods, what they’ve been told is normal [bleeding] – or what they’ve always had and considered normal – is actually kind of on the heavier spectrum,” she said. 

Ideally, treatment for uterine fibroids would fix abnormally prolonged or heavy menstrual bleeding, relieve pain, and ameliorate symptoms associated with an enlarged uterus, such as pelvic pressure, urinary frequency, and constipation. And the fibroids would never recur.

By those measures, hysterectomy fits the bill: Success rates in relieving symptoms are high, and the risk for recurrence is zero. But the procedure carries significant drawbacks: short-term complications of surgery, including infection, bleeding, and injury to the bowels and bladder along with potential long-term risks for cardiovascular disease, cancer, ovarian failure and premature menopause, depression, and decline in cognitive function. Those factors loom even larger for women who still hope to have children. 

For that reason, the American College of Obstetricians and Gynecologists recommends myomectomy, or surgical removal of individual fibroids, for women who desire uterine preservation or future pregnancy. And the literature here is solid, according to Dr. Singh, who found that 95% of myomectomy patients achieved control of their bleeding symptoms, whether it was via laparoscopy, hysteroscopy, or laparotomy. Up to 40% of women may develop new fibroids, or leiomyomas, within 3 years, although only 12.2% required a second surgery up to after 5 years. 

But myomectomy is invasive, requiring general anesthesia, incisions in the uterus, and stitches to close the organ. 

Newer techniques have emerged that can effectively treat symptoms of fibroids without requiring surgery. Uterine artery embolization (UAE), which involves passing a catheter into the femoral artery, or laparoscopic uterine artery occlusion can be used to cut off the blood supply of the fibroid. Other techniques, including focused ultrasound surgery and radiofrequency ablation (RFA), use various forms of energy to heat and ablate fibroids. The latter two can be performed in outpatient settings and often without general anesthesia.

Approved for use in 1994, UAE has the most data available, with reduction in the volume of fibroids and uterine tissue lasting up to 5 years, and rates of reintervention of 19%-38% between 2 and 5 years after the procedure. Dr. Singh’s review found that 79%-98.5% of recipients of the procedure reported declines in bleeding that persisted for several years, which is comparable to myomectomy. Quality of life and pain scores also showed good improvement, with follow-up in the different studies ranging from 12 months to over 5 years, the analysis showed.

UAE does have its drawbacks. In rare cases, embolization can deprive the entire uterus and ovaries of blood, which can cause ovarian dysfunction and potentially result in premature menopause, although this outcome is most common in women who are older than 45 years. The procedure can often also be painful enough that overnight hospitalization is required.

Focused ultrasound surgeries, which include magnetic resonance–guided focused ultrasound surgery (MRgFUS) and high-intensity focused ultrasound (HIFU), were approved by the FDA in 2004. Focused ultrasound waves pass through the abdominal wall and produce significant heating, causing a burn that destroys the targeted tissue without damaging surrounding tissue. As with UAE, improvements in fibroid-associated bleeding and measures of quality of life were similar to those after myomectomy up to 3 years later.

But Dr. Singh noted that both focused ultrasound and RFA can damage the skin or internal organs. “[As] always with the thermal interventions, there is the probability of skin as well as internal organs that might get the thermal energy if it’s not focused correctly on to the fibroid itself,” he said. In addition, MRgFUS is not an option for women who are not good candidates to undergo an MRI, such as those with claustrophobia or pacemakers.

Also, with focus ultrasound and RFA, “we do worry about that fibroid getting blood flow back,” which can lead to recurrence of heavy menstrual bleeding, Dr. Laughlin-Tommaso noted. 

Although data on RFA are limited to 12 months of follow-up, most women reported meaningful reductions in bleeding symptoms. Longer follow-up has been reported for bleeding symptoms after MRgFUS, with similar results up to 3 years later. 

For Leslie Hansen-Lindner, MD, chief of obstetrics and gynecology at Atrium Health in Charlotte, N.C., choosing the right procedure starts with a patient-centered conversation weighing the pros and cons of the options and the woman’s goals. 

“Is their goal to reduce the size and impact of their fibroid, bleed less, and have a better quality of life on their period?” Dr. Hansen-Lindner said. “Or is their goal to have the entire fibroid removed?” 

If the former, an RFA is appealing to many women. If the latter, laparoscopic or mini-laparotomy myomectomy might be a better choice. Although fewer than 10% of patients require surgical reintervention at 3 years of follow-up for RFA, myomectomy has more consistent long-term evidence showing that fewer women require re-intervention and preserve their fertility, she added. 

Age also plays a role in the decision: The closer a woman is to menopause, the less likely she is to experience a recurrence, so a less-invasive procedure is preferable. But for younger women hoping to become pregnant, the lower risk for recurrence and good prognosis for future fertility might sway the choice toward myomectomy.

The first laparoscopic RFA procedures were approved for uterine fibroids in 2012. Dr. Hansen-Lindner is a proponent of transcervical fibroid ablation (TFA), a newer RFA procedure that the FDA approved in 2018. Performed through the cervix, TFA requires no incisions and can generally be done without general anesthesia. Eligible candidates would be any woman with symptomatic fibroids, such as heavy menstrual bleeding, pain, or bulk symptoms. The contraindications are few.

“It’s going to come down to size and location of fibroids, and whether or not they would be accessible by the TFA,” Dr. Hansen-Lindner said. “I have to make sure that there isn’t a fibroid blocking their cervix and that the fibroids are accessible with this device.” 

TFA also is not suitable for removing most submucosal lesions, which typically must be removed by hysteroscopic myomectomy. Dr. Hansen-Lindner said that she often uses TFA in conjunction with hysteroscopic myomectomy for this scenario. Although data on pregnancy after RFA (including TFA), MRgFUS, and HIFU are lacking, Gynesonics, the manufacturer of the Sonata System (the device that delivers radiofrequency energy to shrink the fibroid) has documented 79 pregnancies among the 2,200 women who have undergone TFA in the United States since 2018.
 

Disparities hampering care

Uterine fibroids are a particular problem for Black women, whose symptoms are more likely to be ignored by clinicians, according to Jodie Katon, PhD, a core investigator at the Veterans Affairs Greater Los Angeles Center for the Study of Healthcare Innovation, Implementation and Policy. Dr. Katon cited studies in which Black women interviewed about their experiences reported a consistent theme: Clinicians dismissed their symptoms, told them these were nothing to worry about, and advised them to lose weight. Those interactions not only delayed diagnosis among Black women but also led many of them to mistrust clinicians and avoid the health care system altogether.

The failure of clinicians to take their complaints seriously is just one of the disparities affecting Black women. In reviewing the literature, Dr. Laughlin-Tommaso, who also serves as the associate dean for Education Diversity, Equity, and Inclusion at the Mayo Clinic, found that African American women experience two to three times the risk for fibroids, compared with White women, as well as earlier onset and more severe disease, as measured by number and size of the lesions. 

According to Dr. Katon, the etiology of fibroids is still poorly understood. “What we do know is that Black women are disproportionately exposed to a variety of factors that we have shown through observational studies are associated with increased risk of development of uterine fibroids.” 

The list includes factors like stress; interpersonal racism; early age at menarche; various indicators of poor diets, such as vitamin D deficiency; the use of certain beauty products, specifically hair straighteners; as well as exposure to air pollution and other environmental toxins.

Laughlin-Tommaso also pointed to historical disparities in management, citing a doubled risk for hysterectomy for Black women in a study published in 2007 despite survey data suggesting that Black women report being more interested in uterine-preserving therapies rather than a hysterectomy.
 

Breaking down barriers of access to new treatments

Dr. Laughlin-Tommaso looked at more recent trends in the management of fibroids using data from the multicenter COMPARE-UF study, which enrolled women between 2015 and 2020 undergoing fibroid treatment into a longitudinal registry to track their outcomes. She found that Black women underwent hysterectomies at a lower rate than did White women and were instead more likely to undergo myomectomy or UAE. 

Some of the change may reflect lack of approved minimally invasive procedures before 2000. “But now that we have expanded options, I think most women are opting not to have a hysterectomy,” Dr. Laughlin-Tommaso said.

Dr. Katon has research funding from the VA to look more closely at racial disparities in the treatment of fibroids. In a study published in April 2023, she reported some surprising trends. 

During the period from 2010 to 2018, she found that Black veterans diagnosed with fibroids were less likely than White veterans were to receive treatment, regardless of their age or the severity of their symptoms. This finding held even among women with anemia, which should have been a clear indication for treatment.

But, as in the COMPARE-UF study, the subset of Black veterans who received an interventional treatment were less likely than their White peers were to undergo hysterectomy in favor of a fertility-sparing treatment as their initial procedure. Dr. Katon called it a “welcome but unexpected finding.” 

But another significant barrier remains: The two newest types of procedures, RFA and guided focused ultrasound, are not commonly performed outside of tertiary care facilities. However, studies have found that all these procedures are cost effective (studies for myomectomy, UAE, MRgFUS, and TFA). The implementation of a category 1 billing code for laparoscopic RFA in 2017 has led more insurance companies to cover the service, and a category 1 code will be available for TFA effective January 2024. 

Although RFA does require investment in specialized equipment, which limits facilities from offering the procedure, any gynecologist who routinely performs hysteroscopy can easily learn to do TFA. And the VA, which is committed to eliminating disparities in women’s health, established a 2-year advanced fellowship in minimally invasive gynecologic surgery in 2022 to help expand their capacity to offer these procedures. 

The VA has been rapidly expanding their gynecology services, and Katon said that she is confident that ultrasound-guided procedures and RFA will become more available within the system. “I would say we’re keeping pace. And in some ways, you know, as a national system we may be positioned to actually outpace the rest of the U.S.”

Dr. Segars reported prior research funding for clinical trials from BioSpecifics Technologies, Bayer, Allergan, AbbVie, and ObsEva and currently receives funding from Myovant Sciences. Dr. Hansen-Lindner reported personal fees from Gynesonics. Dr. Singh, Dr. Laughlin-Tommaso, and Dr. Katon reported no financial conflicts of interest.

TOPLINE:

Among children with urine drug screens that are positive for cannabinoids, confirmatory testing based on liquid chromatography–mass spectrometry (LC-MS) may be negative despite detectable concentrations of a cannabis metabolite, according to a research letter published online in JAMA Pediatrics.

METHODOLOGY:

• After a laboratory changed its reporting threshold for the metabolite 11-nor-9-carboxy-Δ9-tetrahydrocannabinol (THC-COOH) from 5 ng/mL to 15 ng/mL in 2019 to match federal standards, researchers examined the rate of false positives for the initial urine drug screen and the false-negative rate with LC-MS.
• Their study focused on 976 cannabinoid-positive drug screens conducted at a pediatric hospital between Nov. 18, 2019, and May 31, 2021, that had confirmatory LC-MS to rule out false-positive results.
• Patients had a median age of 16 years.

TAKEAWAY:

• The false-positive rate was 10.1% based on the 15 ng/mL threshold compared with 2% based on the 5 ng/mL limit of quantification.
• About 81% of samples with negative LC-MS reports had detectable concentrations of THC-COOH.

IN PRACTICE:

“Confirming THC-COOH in children’s and adolescents’ urine may be relevant at concentrations less than 15 ng/mL, particularly if child protection is pertinent,” according to the study authors.

“Confirmatory testing should be reserved for select cases and must be interpreted with caution,” they added. “Laboratories should report down to the limit of quantification on request.”

Posttraumatic stress disorder (PTSD) symptoms are associated with poorer cardiovascular and neurocognitive health among midlife women, particularly those who are APOEε4 carriers, new research suggests.

METHODOLOGY:

• Researchers conducted a cross-sectional study of 274 women (mean age, 59 years) participating in the MsBrain study of menopause and brain health.
• As part of the study, the women completed the PTSD Checklist–Civilian Version and underwent physical and neuropsychological testing, as well as carotid artery ultrasonography and brain MRI.
• Outcomes of interest were associations of PTSD symptoms with carotid intima media thickness (IMT), brain white matter hyperintensity volume (WMHV), and cognition, assessed in linear regression models.
• Interactions by APOEε4 were assessed; covariates included age, race/ethnicity, education, and CVD risk factors.

TAKEAWAY:

• Higher PTSD symptoms were associated with greater carotid IMT (P = .03); associations of PTSD symptoms with neurocognitive outcomes varied significantly by APOEε4 status.
• Among APOEε4 carriers, PTSD symptoms were associated with greater whole-brain WMHV (P = .009), periventricular WMHV (P = .02), deep WMHV (P = .01), and frontal WMHV (P = .04) in multivariable models.
• APOEε4 carriers with PTSD symptoms also had poorer cognition, specifically attention and working memory (P = .02), semantic fluency (P = .01), perceptual speed (P = .002) and processing speed (P = .002), in multivariable models.

IN PRACTICE:

“This study sheds important insight on the implications of PTSD symptoms to women’s cardiovascular and neurocognitive health. Our findings indicate that the APOEε4 genotype may identify a group of women with PTSD symptoms at particular risk for poor neurocognitive health,” the authors wrote.

Drugs offered to treat the headache phase of migraine are not necessarily the best to abort the premonitory or prodromal phases, according to experts attempting to put these puzzle pieces together at the 2023 Scottsdale Headache Symposium.

As the details of the complex chain of molecular events become better understood, there is reason to believe that the targets for aborting events early in the process are not necessarily therapeutic at later stages or vice versa, according to Peter Goadsby, MBBS, MD, PhD, director of the National Institute for Health Research and professor of neurology, King’s College, London.

“I think this explains some of the frustration at trigger modulation. I think we are often trying to modulate a process that has already got started,” he said. The analogy might be closing the barn door after the animals have escaped.
 

Migraine phases might explain pathology

Given the progress in understanding each step that leads from one phase to the next in migraine onset, this premise is not surprising. Increased blood flow, trigeminal activation, and release of calcitonin gene–related peptide (CGRP) are early events in this process, according to Dr. Goadsby, but there is still uncertainty about the triggers of brainstem stimulation and cranial blood flow that precedes these events.

In his talk about the advances that led to the development of CGRP-targeted therapy, Dr. Goadsby explained how and why CGRP inhibition, along with triptans, pituitary adenylate cyclase–activating polypeptide (PACAP) inhibitors, and ditans, have been developed as treatment targets in migraine, while other once-promising targets, such as substance P inhibition and inducible nitric oxide synthase (INOS) inhibition, have not.

Much of this progress has been by trial and error through clinical studies in which efficacy has or has not been seen. Despite the progress in mapping the release of CGRP and its activity, Dr. Goadsby acknowledged that there is still much about its participation in migraine pathophysiology that remains poorly defined.

“Anyone who tells you that they know how CGRP works I think is blowing smoke, frankly,” Dr. Goadsby said. “Clearly these things are complex.”
 

CGRP is active in the CSF

This includes the site of action. Dr. Goadsby said that it is widely believed that CGRP inhibitors are active in the dura and not in the cerebrospinal fluid (CSF). However, Dr. Goadsby said that a study undertaken with monoclonal antibodies targeting CGRP have produced compelling evidence that CGRP is reduced in the CSF.

“They clearly get into the CSF,” said Dr. Goadsby, noting that the barrier between peripheral blood and the CSF “is different from the blood-brain barrier.”

Widely regarded as playing a pivotal role in the development of CGRP as a therapeutic target in migraine, Dr. Goadsby spent some time speculating about its potential for preventing the earliest steps in the process that leads from the premonitory state to allodynia, prodromal symptoms, migraine, and postdromal recovery.

Of triggers, “light is my favorite example,” he said. He noted that many patients are convinced that light initiates the subsequent steps that end in a migraine. This is fair assumption for those who have seen a sequence of events in which light in the absence of any other symptom always precedes prodromal symptoms and migraine.

“Why would you not think that?” he asked. “Unless you point out that the attack had already started and the reason that you are noticing the light is because of photophobia that started during the premonitory phase.”

It is increasingly clear that CGRP inhibition does have clinical benefit when started at early signs of a coming migraine, according to Dr. Goadsby. He cited a phase 3 study published just days before he spoke at the Scottsdale Headache Symposium. Called PRODROME, the study associated the CGRP receptor antagonist ubrogepant, which is already approved for treatment of migraine, with a significant reduction in the risk of moderate to severe headache relative to placebo when measured 24 hours after randomization (46% vs. 29%; P < .0001).


 

Brain activity monitoring supports phases

Citing imaging studies in his own laboratory, Todd J. Schwedt, MD, chair of neurology research, Mayo Clinic, Phoenix, substantiated several of the points made by Dr. Goadsby in a separate talk he made on migraine phases. By monitoring brain activity during each phase of migraine, he suggested his data support the role of CGRP in producing an inflammatory response as well as sensitizing the trigeminal cervical system in steps that appear to be important to the pain process.

Mitchel L. Zoler/MDedge News

Dr. Schwedt showed several pieces of evidence suggesting that CGRP is an early mediator even if it is not necessarily the first step in a process for every patient. However, like Dr. Goadsby, Dr. Schwedt also acknowledged that the interplay between events is complex and might differ between patients.

Yet, he says that brain activity on imaging is not the only evidence of the role of CGRP activation early in the process leading toward migraine.

“I am a little biased towards imaging, but it’s not just about imaging,” Dr. Schwedt said.

“If we look at preictal salivary CGRP levels and then follow them into the headache phase, we see the levels increase, but they go back to normal a couple of hours into the attack and then stay normal, presumably, until the patient gets closer to the next attack,” Dr. Schwedt said.

Despite progress there is more to be done to determine why CGRP is released and whether it can be inhibited early to abort migraine before the headache phase, but both Dr. Goadsby and Dr. Schwedt pointed to this as a very early event. This is not to say that others, such as cortical spreading depression, do not have an equally important role in the evolution of migraine, but each expert considers migraine phases to be useful divisions for tracing the sequence of pathogenic events.

The phase of a migraine attack and their corresponding symptoms “can be mapped to altered brain function and release of neuropeptides and neurotransmitters,” Dr. Schwedt said. The implication is that better targets for blocking migraine before it reaches the headache phase might be discovered in these early phases.

Dr. Goadsby and Dr. Schwedt listed more than 10 pharmaceutical companies to which they have financial relationships, but both claimed that none of these relationships posed a potential conflict of interest.

In his talk about the advances that led to the development of CGRP-targeted therapy, Dr. Goadsby explained how and why CGRP inhibition, along with triptans, pituitary adenylate cyclase–activating polypeptide (PACAP) inhibitors, and ditans, have been developed as treatment targets in migraine, while other once-promising targets, such as substance P inhibition and inducible nitric oxide synthase (INOS) inhibition, have not.

Much of this progress has been by trial and error through clinical studies in which efficacy has or has not been seen. Despite the progress in mapping the release of CGRP and its activity, Dr. Goadsby acknowledged that there is still much about its participation in migraine pathophysiology that remains poorly defined.

“Anyone who tells you that they know how CGRP works I think is blowing smoke, frankly,” Dr. Goadsby said. “Clearly these things are complex.”
 

CGRP is active in the CSF

This includes the site of action. Dr. Goadsby said that it is widely believed that CGRP inhibitors are active in the dura and not in the cerebrospinal fluid (CSF). However, Dr. Goadsby said that a study undertaken with monoclonal antibodies targeting CGRP have produced compelling evidence that CGRP is reduced in the CSF.

“They clearly get into the CSF,” said Dr. Goadsby, noting that the barrier between peripheral blood and the CSF “is different from the blood-brain barrier.”

Widely regarded as playing a pivotal role in the development of CGRP as a therapeutic target in migraine, Dr. Goadsby spent some time speculating about its potential for preventing the earliest steps in the process that leads from the premonitory state to allodynia, prodromal symptoms, migraine, and postdromal recovery.

Of triggers, “light is my favorite example,” he said. He noted that many patients are convinced that light initiates the subsequent steps that end in a migraine. This is fair assumption for those who have seen a sequence of events in which light in the absence of any other symptom always precedes prodromal symptoms and migraine.

“Why would you not think that?” he asked. “Unless you point out that the attack had already started and the reason that you are noticing the light is because of photophobia that started during the premonitory phase.”

It is increasingly clear that CGRP inhibition does have clinical benefit when started at early signs of a coming migraine, according to Dr. Goadsby. He cited a phase 3 study published just days before he spoke at the Scottsdale Headache Symposium. Called PRODROME, the study associated the CGRP receptor antagonist ubrogepant, which is already approved for treatment of migraine, with a significant reduction in the risk of moderate to severe headache relative to placebo when measured 24 hours after randomization (46% vs. 29%; P < .0001).


 

Brain activity monitoring supports phases

Citing imaging studies in his own laboratory, Todd J. Schwedt, MD, chair of neurology research, Mayo Clinic, Phoenix, substantiated several of the points made by Dr. Goadsby in a separate talk he made on migraine phases. By monitoring brain activity during each phase of migraine, he suggested his data support the role of CGRP in producing an inflammatory response as well as sensitizing the trigeminal cervical system in steps that appear to be important to the pain process.

Dr. Schwedt showed several pieces of evidence suggesting that CGRP is an early mediator even if it is not necessarily the first step in a process for every patient. However, like Dr. Goadsby, Dr. Schwedt also acknowledged that the interplay between events is complex and might differ between patients.

Yet, he says that brain activity on imaging is not the only evidence of the role of CGRP activation early in the process leading toward migraine.

“I am a little biased towards imaging, but it’s not just about imaging,” Dr. Schwedt said.

“If we look at preictal salivary CGRP levels and then follow them into the headache phase, we see the levels increase, but they go back to normal a couple of hours into the attack and then stay normal, presumably, until the patient gets closer to the next attack,” Dr. Schwedt said.

Despite progress there is more to be done to determine why CGRP is released and whether it can be inhibited early to abort migraine before the headache phase, but both Dr. Goadsby and Dr. Schwedt pointed to this as a very early event. This is not to say that others, such as cortical spreading depression, do not have an equally important role in the evolution of migraine, but each expert considers migraine phases to be useful divisions for tracing the sequence of pathogenic events.

The phase of a migraine attack and their corresponding symptoms “can be mapped to altered brain function and release of neuropeptides and neurotransmitters,” Dr. Schwedt said. The implication is that better targets for blocking migraine before it reaches the headache phase might be discovered in these early phases.

Dr. Goadsby and Dr. Schwedt listed more than 10 pharmaceutical companies to which they have financial relationships, but both claimed that none of these relationships posed a potential conflict of interest.

Drugs offered to treat the headache phase of migraine are not necessarily the best to abort the premonitory or prodromal phases, according to experts attempting to put these puzzle pieces together at the 2023 Scottsdale Headache Symposium.

As the details of the complex chain of molecular events become better understood, there is reason to believe that the targets for aborting events early in the process are not necessarily therapeutic at later stages or vice versa, according to Peter Goadsby, MBBS, MD, PhD, director of the National Institute for Health Research and professor of neurology, King’s College, London.

“I think this explains some of the frustration at trigger modulation. I think we are often trying to modulate a process that has already got started,” he said. The analogy might be closing the barn door after the animals have escaped.

Adults with Parkinson’s disease are twice as likely to engage in suicidal behavior as the general population, results of a large meta-analysis show.

Given that up to half of patients with PD suffer from depression and anxiety, physicians should maintain a “high index of suspicion” for early recognition and management of suicidality, write the investigators, led by Eng-King Tan, MD, of Duke-NUS Medical School, Singapore.

“Management of both medical, such as sleep disorders, and psychosocial risk factors, such as feelings of loneliness, hopelessness, and depressed mood, could be useful in lowering suicide risk in patients with PD,” they add.

The study was published online  in JAMA Neurology.
 

Suicide risk neglected in PD?

The analysis included 505,950 patients with PD across 28 cross-sectional, case-control, and cohort studies.

Across 14 studies, the prevalence of suicidal ideation in patients with PD was 22.2% (95% confidence interval, 14.6-32.3). In a sensitivity analysis excluding three outliers, the prevalence of suicidal ideation was higher at 24% (95% CI, 19.1-29.7).

Across 21 studies, the prevalence of suicidal behavior was “substantial” at 1.25% (95% CI, 0.64-2.41), the authors report. The prevalence of suicidal behavior was significantly higher in prospective studies (1.75%; 95% CI, 1.03-2.95) than retrospective studies (0.50%; 95% CI, 0.24 to 1.01).

Across 10 studies, the likelihood of suicidal behavior was about twofold higher among patients with PD than general population controls (odds ratio, 2.15; 95% CI, 1.22-3.78; P = .01). Across nine studies, the hazard ratio for suicidal behavior was 1.73 (95% CI, 1.40-2.14; P < .001).

There was no evidence of sex-related differences in suicidal behavior, although the analysis was limited by the paucity of data, the researchers note. 

They note the quality of included studies was generally high, although eight of them did not explicitly identify and adjust for confounders.
 

Higher rate of mood, anxiety disorders

Paul Nestadt, MD, with Johns Hopkins Bloomberg School of Public Health, Baltimore, said this analysis reiterates what several reviews have found over the past few years, including his own.

“In general, rates of mood and anxiety disorders are much higher in PD than in other dementias, such as Alzheimer’s disease. This is reason enough to allocate resources to the mental health care of those diagnosed with PD and to pay special attention to at risk periods, such as early in the diagnosis, when suicide rates seem to be higher in dementias in general,” said Dr. Nestadt, who wasn’t involved in the study.

He noted that research has shown that suicides among people with PD are more likely to involve a firearm – likely because people with PD are more likely to be over age 65 and to be male – “both huge risk factors for firearm suicide.”

“Therefore, it is essential that caregivers be aware of the risks posed by firearms in the homes of people suffering from Parkinson’s or other dementias. It is the clinician’s responsibility to inform families of this risk, but it is all too often neglected,” Dr. Nestadt said.

Support for the study was provided in part by the National Medical Research Council. Dr. Tan reported honoraria from Eisai and Elsevier outside the submitted work. Dr. Nestadt reports no relevant financial relationships.

TOPLINE:

Left atrial appendage closure was associated with about half as many disabling or fatal strokes and lower mortality after a stroke, compared with dual oral anticoagulant therapy in patients with atrial fibrillation (AFib), new observational research shows.

METHODOLOGY:

• The retrospective registry analysis included 447 adult patients with nonvalvular AFib, mean age 74 years, who were hospitalized with an ischemic stroke, 322 of whom were receiving direct oral anticoagulant (DOAC) therapy, mostly (84%) apixaban or rivaroxaban, and 125 were treated with left atrial appendage closure (LAAC), almost all (97%) with Watchman or Watchman-FLX devices.
• All patients received standard stroke care, monitoring, and treatment as well as physical therapy/rehabilitation.
• For the primary outcome, researchers used the modified Rankin Scale (mRS) to determine disabling (mRS score of 3-5) and fatal (mRS score of 6) strokes at discharge and at 3 months.
• The study adjusted for age, smoking, paroxysmal AFib, prior major bleeding, prior hemorrhagic stroke, medication adherence, and other risk factors.

TAKEAWAY:

• The incidence of disabling or fatal IS was significantly lower with LAAC versus with DOAC at discharge (38.3% vs. 70.3%; P < .001) and at 3 months (33.3% vs. 56.2%; P < .001), even though the LAAC group had more baseline comorbidity, for example, older age, more smokers, and more prior major bleeding.
• There was no significant difference in mortality between groups during hospitalization, but at 3 months, mortality was lower in the LAAC group (14.7% vs. 32.1%; P = .002).
• Multivariate linear regression analysis showed LAAC independently predicted more favorable mRS at discharge (2.8) and 3 months (1.4) (both P < .001) and was associated with less all-cause death at 3 months (odds ratio, 0.28; 95% confidence interval, 0.12-0.64; P = .002).
• Including those that excluded the 14.4% of LAAC patients who also received DOAC therapy, sensitivity analyses patients who got reduced dose DOACs and nonadherent patients yielded nearly identical outcomes to the full cohort analysis.

IN PRACTICE:

“Despite a higher baseline risk profile, patients treated with LAAC who developed IS had better outcomes than those receiving DOAC prophylaxis,” the authors conclude, adding that several ongoing prospective trials could, “shed light on the mechanism(s) responsible for differences in stroke severity.”

SOURCE:

The study was conducted by Mohit K. Turagam, MD, Icahn School of Medicine at Mount Sinai, New York, and colleagues. It was published online in JACC: Clinical Electrophysiology.

LIMITATIONS:

Despite sensitivity analyses and adjustment for risk factors, selection bias, missing data, and other confounding factors could have affected outcomes. The study didn’t evaluate recurrent IS or type and intensity of rehabilitation on outcomes. Lack of imaging data comparing stroke infarct size and volume limits understanding of exact mechanism driving higher stroke severity with DOACs. Because patients who died before reaching hospital weren’t captured in the registry, the actual mortality may be higher than reported.

DISCLOSURES:

Dr. Turagam has served as a consultant for Biosense Webster and Sanofi.

TOPLINE:

Updated data from the OPRA trial show that nearly half of patients with stage II/III rectal cancer treated with total neoadjuvant therapy preserved their rectums over 5 years, with local tumor regrowth occurring mostly within the first 2 years.

METHODOLOGY:

• Many patients with locally advanced rectal cancer treated with total neoadjuvant therapy in the OPRA trial achieved a complete or near-complete tumor response and were initially offered a watch-and-wait strategy.
• However, nearly one-third of patients receiving watch-and-wait developed local tumor regrowth and ultimately required total mesorectal excision (TME).
• The study team reported updated organ preservation rates and oncologic outcomes in the OPRA trial of 324 patients with stage II/III rectal cancer randomized to induction chemotherapy followed by chemoradiation (n = 158) or chemoradiation followed by consolidation chemotherapy (n = 166).
• Among the 304 patients restaged a median of 7.8 weeks after finishing total neoadjuvant therapy, investigators recommended TME in 26% and watch-and-wait in 74% (n = 225).

TAKEAWAY:

• The researchers reported similar 5-year disease-free survival among patients in the induction chemotherapy group (71%) and the consolidation chemotherapy group (69%). The estimated 5-year overall survival rates were also similar in the two groups – 88% in the induction group vs. 85% in the consolidation group.
• Among the patients who received watch-and-wait, 36% (n = 81) experienced tumor regrowth; 94% occurred within 2 years and 99% occurred within 3 years.
• An estimated 39% of patients in the induction chemotherapy group and 54% in the consolidation chemotherapy group achieved organ preservation at 5 years, representing about half of patients overall.
• Among the patients who received watch-and-wait, salvage TME following tumor regrowth appeared to offer disease-free survival (64% of patients) similar to immediate TME after incomplete response to total neoadjuvant therapy (also 64%).

IN PRACTICE:

Total neoadjuvant therapy among patients with rectal cancer “resulted in long-term organ preservation in half of the patients,” the authors concluded. Although the order of therapy did not affect survival, consolidation chemotherapy “resulted in higher organ preservation at 5 years.”

“Our results support the recommendation that patients with rectal cancer offered [watch-and-wait] after neoadjuvant therapy should have very close surveillance during the first 3 years,” the authors added.

TOPLINE:

Updated data from the OPRA trial show that nearly half of patients with stage II/III rectal cancer treated with total neoadjuvant therapy preserved their rectums over 5 years, with local tumor regrowth occurring mostly within the first 2 years.

METHODOLOGY:

• Many patients with locally advanced rectal cancer treated with total neoadjuvant therapy in the OPRA trial achieved a complete or near-complete tumor response and were initially offered a watch-and-wait strategy.
• However, nearly one-third of patients receiving watch-and-wait developed local tumor regrowth and ultimately required total mesorectal excision (TME).
• The study team reported updated organ preservation rates and oncologic outcomes in the OPRA trial of 324 patients with stage II/III rectal cancer randomized to induction chemotherapy followed by chemoradiation (n = 158) or chemoradiation followed by consolidation chemotherapy (n = 166).
• Among the 304 patients restaged a median of 7.8 weeks after finishing total neoadjuvant therapy, investigators recommended TME in 26% and watch-and-wait in 74% (n = 225).

TAKEAWAY:

• The researchers reported similar 5-year disease-free survival among patients in the induction chemotherapy group (71%) and the consolidation chemotherapy group (69%). The estimated 5-year overall survival rates were also similar in the two groups – 88% in the induction group vs. 85% in the consolidation group.
• Among the patients who received watch-and-wait, 36% (n = 81) experienced tumor regrowth; 94% occurred within 2 years and 99% occurred within 3 years.
• An estimated 39% of patients in the induction chemotherapy group and 54% in the consolidation chemotherapy group achieved organ preservation at 5 years, representing about half of patients overall.
• Among the patients who received watch-and-wait, salvage TME following tumor regrowth appeared to offer disease-free survival (64% of patients) similar to immediate TME after incomplete response to total neoadjuvant therapy (also 64%).

PHILADELPHIA – An investigational PCSK9 inhibitor that can be injected every 1-3 months as add-on therapy for patients with stubbornly high low-density lipoprotein (LDL) cholesterol has demonstrated cholesterol lowering for up to a year, in a clinical trial.

The results are from the phase 3 Recaticimab Add-On Therapy in Patients With Non-Familial Hypercholesterolemia and Mixed Hyperlipidemia (REMAIN-2) trial.

“It’s a new antibody that has a long half-life so each treatment can be prolonged,” investigator Xin Du, MD, professor of cardiology at Beijing Anzhen Hospital and the Capital Medical University, said in an interview. “Previous drugs like alirocumab and evolocumab have to be given every 2 weeks or every 4 weeks, and this new drug can be given even every 12 weeks, so it can get a very strong effect of LDL cholesterol lowering even when given every 3 months.”

Recaticimab has demonstrated a half-life of 18.6 to 27.4 days vs. 11 to 17 days for alirocumab and evolocumab, she said.

“Currently a high proportion of patients prescribed the PCSK9 inhibitors withdraw from therapy,” Dr. Du said. “After 36 months, only half of them are still on that therapy.”

Dr. Du presented the trial results at the annual scientific sessions of the American Heart Association.
 

Trial design and results

REMAIN-2 randomly assigned 692 patients to one of three recaticimab dosing arms vs. placebo: 150 mg/kg every 4 weeks; 300 mg/kg every 8 weeks; and 450 mg/kg every 12 weeks. The study was conducted from June 2021 to March 2023. The average age of the participants was 56 years and 64% were men. A high percentage of patients, 87% to 93.5%, completed the study across all groups. All participants had high LDL-C levels despite statin therapy: ≥ 70 mg/dL for those with cardiovascular disease and ≥ 100 mg/dL for those without.

Recaticimab enhanced LDL-C reduction by 53.4% to 62% vs. placebo at 24 weeks with a similar effect across all dosing regimens, Dr. Du said. That level of reduction was sustained out to 48 weeks, she said, at 48.4% to 64%.

At week 24, 86% to 94.5% of all patients across the three dosing arms achieved their LDL-C goal. The treatment had a positive impact on other lipid levels as well, Dr. Du said. Levels of non-HDL-C declined 55% to 47%. Apolipoprotein B (ApoB) levels fell 53% to 42% and lipoprotein (a), or Lp(a) readings declined 39.5% to 29%. The placebo arms had no change or small increases in non-HDL-C and ApoB levels and modest reductions in Lp(a).

The trial demonstrated acceptable safety and tolerability of recaticimab, Dr. Du said. At 48 weeks, the rates of injection site reactions were 3.9% in the treatment arms vs. 1.3% in the placebo arms. Common adverse events with a frequency ≥ 5% in patients receiving recaticimab were upper respiratory tract infection, hyperuricemia, urinary tract infection, increased blood creatine phosphokinase – a marker of damage to the heart – COVID-19 infection, and increased alanine transferase and aspartate transferase, both of which are markers of liver damage.
 

Larger, longer studies needed

Longer-term studies of recaticimab are still needed to determine its ability produce durable LDL-C reduction in a cost-effective manner, said discussant Stephen Nicholls, MD, director of Victorian Heart Institute and professor at Monash University in Australia. “It is important to note that these are still relatively short studies and the short treatment period cannot exclude the formation of neutralizing antibodies that have undermined development of other humanized antibodies,” he told attendees.

The every-12-week dosing, Dr. Nicholls said in an interview, “provides a dosing regimen that may be palatable to many patients.”

Besides the potential for the development of antibodies, Dr. Nicholls foresaw potential challenges with recaticimab. “The reality will lie in longer-term data,” he said. “If they can achieve durable lipid lowering without such neutralizing antibodies that would be very good.”

Dr. Nicholls added, “There’s a lot going on in the PCSK9 inhibitor space and the challenge for any new therapeutic, including this one, is where will it fit in given the space is getting crowded. So, data is important and clinical uptake will be equally important.”

Dr. Du disclosed relationships with Sanofi, AstraZeneca and Bayer. Dr. Nicholls disclosed relationships with AstraZeneca, Akcea, Amarin, Amgen, Anthera, Boehringer Ingelheim, Cerenis, CSL Behring, Eli Lilly, Esperion, Novartis,  LipoScience, The Medicines Company, Merck, New Amsterdam Pharma, Omthera, Resverlogix, InfraReDx, Roche, Sanofi-Regeneron, Takeda, Vaxxinity, and Seqirus.

TOPLINE:

A 3-month yoga program that integrates deep breathing, meditation, and positive affirmations is associated with a significant reduction in seizure frequency, anxiety, and self-perceived feelings of stigma in people with epilepsy, a new study shows.

METHODOLOGY:

• Investigators included participants aged 18-60 years with epilepsy who scored ≥ 4 on the Kilifi Stigma Scale of Epilepsy. A score greater than the 66th percentile indicates the presence of strongly felt stigma.
• Patients (n = 160) had an average of one seizure per week, and most took at least two antiseizure medications.
• The intervention group (n = 80) participated in a yoga module with muscle-loosening exercises, slow and synchronized breathing, meditation, and positive affirmations. The control group (n = 80) participated in sham yoga sessions with no instructions on the breathing exercises or attention to the body movements and sensations during practice.
• Both groups participated in seven 1-hour supervised group yoga sessions over 3 months, were asked to practice the interventions at home five times per week, and received a psychoeducation module on epilepsy.

TAKEAWAY:

• Participants practicing the intervention module had significant reductions in self-perceived stigma, compared with those in the control group (P = .01).
• The proportion of participants in the intervention group who had a more than 50% seizure reduction (odds ratio, 4.11; P = .01) and complete seizure remission (OR, 7.4; P = .005) at the end of the 6-month follow-up was significantly higher than in the control group.
• Compared with those in the control group, there were also significant improvements in anxiety (P = .032) and quality of life (P < .001) in the intervention group.
• The intervention group also experienced significant improvement in mindfulness (P < .001) and cognitive impairment, compared with the control group (P < .004).

IN PRACTICE:

“This stigma can affect a person’s life in many ways, including treatment, emergency department visits, and poor mental health,” study investigator Majari Tripathi, MD, of All India Institute of Medical Sciences, New Delhi, said in a press release. “Our study showed that doing yoga can alleviate the burden of epilepsy and improve the overall quality of life by reducing this perceived stigma.”

SOURCE:

Dr. Tripathi and Kirandeep Kaur, MD, also of All India Institute of Medical Sciences, conducted the study with their colleagues. It was published online in Neurology.

LIMITATIONS:

There was no passive control or treatment as usual group, which would indicate the effect size of the intervention. In addition, there was no monitoring of seizure frequency before the study began, which may have biased the change of seizure frequency as an outcome.

DISCLOSURES:

The study investigators reported no study funding or reported disclosures.
