Diabetes drug tied to lower dementia risk
new research suggests.
Overall, in a large cohort study from South Korea, patients who took pioglitazone were 16% less likely to develop dementia over an average of 10 years than peers who did not take the drug.
However, the dementia risk reduction was 54% among those with ischemic heart disease and 43% among those with a history of stroke.
“Our study was to see the association between pioglitazone use and incidence of dementia, not how (with what mechanisms) this drug can suppress dementia pathology,” coinvestigator Eosu Kim, MD, PhD, Yonsei University, Seoul, South Korea, said in an interview.
However, “as we found this drug is more effective in diabetic patients who have blood circulation problems in the heart or brain than in those without such problems, we speculate that pioglitazone’s antidementia action may be related to improving blood vessel’s health,” Dr. Kim said.
This finding suggests that pioglitazone could be used as a personalized treatment approach for dementia prevention in this subgroup of patients with diabetes, the researchers noted.
The results were published online in Neurology.
Dose-response relationship
Risk for dementia is doubled in adults with T2DM, the investigators wrote. Prior studies have suggested that pioglitazone may protect against dementia, as well as a first or recurrent stroke, in patients with T2DM.
This led Dr. Kim and colleagues to examine the effects of pioglitazone on dementia risk overall and in relation to stroke and ischemic heart disease.
Using the national Korean health database, the researchers identified 91,218 adults aged 50 and older with new-onset T2DM who did not have dementia. A total of 3,467 were treated with pioglitazone.
Pioglitazone exposure was defined as a total cumulative daily dose of 90 or more calculated from all dispensations during 4 years after T2DM diagnosis, with outcomes assessed after this period.
Over an average of 10 years, 8.3% of pioglitazone users developed dementia, compared with 10.0% of nonusers.
There was a statistically significant 16% lower risk for developing all-cause dementia among pioglitazone users than among nonusers (adjusted hazard ratio, 0.84; 95% confidence interval, 0.75-0.95).
A dose-response relationship was evident; pioglitazone users who received the highest cumulative daily dose were at lower risk for dementia (aHR, 0.72; 95% CI, 0.55-0.94).
Several limitations
The reduced risk for dementia was more pronounced among patients who used pioglitazone for 4 years in comparison with patients who did not use the drug (aHR, 0.63; 95% CI, 0.44-0.90).
The apparent protective effect of pioglitazone with regard to dementia was greater among those with a history of ischemic heart disease (aHR, 0.46; 95% CI, 0.24-0.90) or stroke (aHR, 0.57; 95% CI, 0.38-0.86) before diabetes diagnosis.
The incidence of stroke was also reduced with pioglitazone use (aHR, 0.81; 95% CI, 0.66-1.0).
“These results provide valuable information on who could potentially benefit from pioglitazone use for prevention of dementia,” Dr. Kim said in a news release.
However, “the risk and benefit balance of long-term use of this drug to prevent dementia should be prospectively assessed,” he said in an interview.
The researchers cautioned that the study was observational; hence, the reported associations cannot address causal relationships. Also, because of the use of claims data, drug compliance could not be guaranteed, and exposure may have been overestimated.
There is also the potential for selection bias, and no information on apolipoprotein E was available, they noted.
More data needed
In an accompanying editorial, Colleen J. Maxwell, PhD, University of Waterloo (Ont.), and colleagues wrote that the results “not only support previous studies showing the potential cognitive benefit of pioglitazone but also extend our understanding of this benefit through the mediating effect of reducing ischemic stroke.”
However, because of their associated risks, which include fractures, weight gain, heart failure, and bladder cancer, thiazolidinediones are not currently favored in diabetes management guidelines – and their use has significantly declined since the mid to late 2000s, the editorialists noted.
They agreed that it will be important to reassess the risk-benefit profile of pioglitazone in T2DM as additional findings emerge.
They also noted that sodium-glucose cotransporter-2 inhibitors, which have significant cardiovascular and renal benefits and minimal side effects, may also lower the risk for dementia.
“As both pioglitazone and SGLT-2 inhibitors are second-line options for physicians, the current decision would easily be in favor of SGLT-2 inhibitors given their safety profile,” Dr. Maxwell and colleagues wrote.
For now, pioglitazone “should not be used to prevent dementia in patients with T2DM,” they concluded.
The study was supported by grants from the National Research Foundation of Korea funded by the Korean government and the Ministry of Health and Welfare. The investigators and editorialists report no relevant financial relationships.

FROM NEUROLOGY
‘Only a sociopath could work for a large health system,’ doc says sardonically
A frustrated physician recently voiced some strong words in Medscape’s US Physician Burnout & Depression Report: “Only a sociopath could work for a large health system and not be burned out. Anyone who cares about patients is doomed to burnout.”
Medscape’s report showed that 53% of physicians feel burned out by job requirements; 65% say that burnout has impacted their relationships, and other statistics say that physicians are leaving clinical medicine because of all this pressure.
What is it about being employed by large organizations that can be so negative? In another study, MEMO – Minimizing Error, Maximizing Outcomes – researchers at the University of Wisconsin surveyed more than 400 doctors to learn about how their working environments corresponded with medical errors. More than half of the physicians reported time pressures when conducting physical examinations. Nearly a third felt they needed at least 50% more time than was allotted for this patient care function, and nearly a quarter said they needed at least 50% more time for follow-up appointments.
Some have asked: Can anyone, then, thrive in today’s health care environment and avoid burnout?
Although the frustrated physician noted above may sardonically say that a doctor needs to be sociopathic to enjoy it – lacking in feelings for others – “It’s a very small number of doctors who get in it for the wrong reasons and therefore care about their own benefit and not their patients,” said psychiatrist Wendy Dean, MD, CEO and cofounder of Moral Injury of Healthcare, a nonprofit organization addressing workforce distress in health care. “Those are the outliers.”
The vast majority of physicians do care about their patients – deeply, said Dr. Dean. They struggle under the weight of the health care system and yet must find ways to get through. Today, thriving in an imperfect system requires honing new skills, asking for help when needed, and pushing for systemic and cultural change.
“We’ve been assessing and trying to address burnout for half a century,” said Dr. Dean. “Despite all the good intentions, and people dedicating their entire careers to solving the issue, we’ve barely made a dent.”
With the advent of new technological requirements on the job and more demands from increasingly larger health care organizations, the risk for burnout is higher than ever before. “There’s an increased burden of regulatory-mandated and cumbersome administrative workload per patient,” said Shomron Ben-Horin, MD, cofounder of Evinature. “Often the computer/paperwork before and after a procedure is much longer than the procedure itself.”
Meeting insurance requirements is increasingly cumbersome, too, and preauthorizations and debates with payers over medical approval may put physicians frustratingly in the middle.
“This increases the psychological burden for physicians who may feel responsible for wrongdoing no matter which option they deem better,” Dr. Ben-Horin said. “Add in physician accessibility around the clock via mobile phones, emails, and apps, and you end up on call even if you’re not officially on call.”
Why some physicians suffer more
Some physicians are more likely to suffer burnout than others, said Jessi Gold, MD, assistant professor in the department of psychiatry at Washington University in St. Louis. “The self-valuation concept comes into play here,” she said. “If you make a mistake, do you blame yourself or see it as a growth opportunity? If it’s the former, you’re more likely to burn out.”
Dr. Ben-Horin added that the most patient-centric doctors are the ones who struggle most. “These are the doctors we’d all love to have as a patient,” he said. “But they are burdened by the extra tasks of the job, and they are the most stressed by the environment.”
So too are those physicians who never master compartmentalizing their feelings and emotions. “We learn in training to compartmentalize our emotions,” said Dr. Dean. “You can’t allow yourself to get emotional while performing chest compressions on an 18-year-old kid. So you shut it all away; otherwise, you might lose the patient.”
This turn-off switch becomes automatic, but it also comes at a cost. “When doctors were interviewed about [Buffalo Bills player] Damar Hamlin going into cardiac arrest on the football field, they talked about how a life-and-death situation is so common that they have to put the emotions away, work on the patient, and move onto the next,” said Dr. Dean. “The next patient needs you just as much. We must lock away our feelings and manage the situation.”
Dr. Gold explained that burying feelings, however, is a symptom of burnout. “We have to remove ourselves from the situation to protect ourselves,” she said. “We can’t cry in these situations, but we can’t bury our feelings either.”
Instead, Dr. Gold suggested, a good medium may exist. “You may not be able to address them in the moment, but you should sometime after,” she said.
This is just a starting point on how to remain a dedicated, caring physician without burning out. “The system is pretty broken, and to survive it first means wanting to survive it,” Dr. Gold said. “There’s a lot of focus on resiliency and lack thereof if a physician expresses burnout, but that’s a false notion. Doctors are a resilient bunch but even they get burned out.”
Change for the better must come from several places. One is asking for help, something that can be hard for a group conditioned to keeping a stiff upper lip. “Just because your peers might look healthy (emotionally) doesn’t mean they are,” said Dr. Gold. “We’ve normalized this culture of burying feelings, but that doesn’t mean it’s right.”
Dr. Ben-Horin also advocates diversifying your work. This might include engaging in research and academics, for instance. “This not only makes you a better broad-perspective doctor but allows you to psychologically switch gears on research days,” he said.
The biggest place to make change, however, is within the health care system culture itself. The AMA created a series of recommendations to address burnout at the resident and fellow level, a good starting point to carry through into staff work. The steps include creating a well-being framework, gathering a team to support a well-being program, developing the program in a way to foster fun and connectivity among the staff, fostering individual well-being that addresses emotional and physical well-being, and confronting burnout and creating a sustainable culture of well-being.
On a personal level, it’s essential that physicians keep close tabs on themselves and peers. “Understand the signs and symptoms of burnout by taking stock of where you are emotionally,” said Dr. Gold. “Have a place and time at the end of a hard day to reflect or find a ritual that helps you and stay with it.”
You might also reach out to a therapist or a peer when you’re struggling. Having honest conversations with peers can go a long way. “Find a confidant that allows you to be vulnerable,” Dr. Gold recommended. “Acknowledge that this is hard and that you might need help taking care of yourself. The system needs to change, but we can also learn to survive in the meantime. You don’t have to be a sociopath to make it.”

Doctors are a resilient bunch but even they get burned out.”
Change for the better must come from several places. One is asking for help, something that can be hard for a group conditioned to keeping a stiff upper lip. “Just because your peers might look healthy (emotionally) doesn’t mean they are,” said Dr. Gold. “We’ve normalized this culture of burying feelings, but that doesn’t mean it’s right.”
Dr. Ben-Horin also advocates diversifying your work. This might include engaging in research and academics, for instance. “This not only makes you a better broad-perspective doctor but allows you to psychologically switch gears on research days,” he said.
The biggest place to make change, however, is within the health care system culture itself. The AMA created a series of recommendations to address burnout at the resident and fellow level, a good starting point to carry through into staff work. The steps include creating a well-being framework, gathering a team to support a well-being program, developing the program in a way to foster fun and connectivity among the staff, fostering individual well-being that addresses emotional and physical well-being, and confronting burnout and creating a sustainable culture of well-being.
On a personal level, it’s essential that physicians keep close tabs on themselves and peers. “Understand the signs and symptoms of burnout by taking stock of where you are emotionally,” said Dr. Gold. “Have a place and time at the end of a hard day to reflect or find a ritual that helps you and stay with it.”
You might also reach out to a therapist or a peer when you’re struggling. Having honest conversations with peers can go a long way. “Find a confidant that allows you to be vulnerable,” Dr. Gold recommended. “Acknowledge that this is hard and that you might need help taking care of yourself. The system needs to change, but we can also learn to survive in the meantime. You don’t have to be a sociopath to make it.”

Not always implemented or enforced: Harassment policies at work
Many companies, government agencies, and organizations have implemented policies and procedures to shield employees from sexual and other forms of harassment. The U.S. Department of Health & Human Services and the American Medical Association are just two examples.
Employers can tap a rich lode of guidance and resources to craft these antiharassment policies. The National Institutes of Health’s resource page is a good site for hospitals to check out.
But how effective have official policies proved in deterring harassment in medical workplaces? After all, in a study by the American Association of Medical Colleges, 34% of female faculty said they had experienced sexual harassment irrespective of such policies. And in a recent Medscape survey of more than 3,000 physicians, 27% reported that they had either witnessed or been subjected to sexual harassment or misconduct at work during the past 4 years.
When policies are absent or unenforced
She believes employer rules and policies generally are helpful in establishing who fields harassment complaints and in creating at least some accountability.
On the other hand, policies that don’t recognize anonymous complaints effectively discourage harassment victims from coming forward, Dr. Rohr-Kirchgraber argues. Even those policies that do allow anonymous complaints may have limitations.
For example, the NIH policy on reporting harassment acknowledges that “officials must follow up on all allegations of harassment and cannot guarantee that your identity will not become apparent during the process. Please note that if you remain anonymous, key details about the allegation or concern [may] be omitted. This will limit the NIH’s ability to conduct an inquiry and take corrective action as warranted.”
Risks in pressing a harassment case
A complainant whose name becomes public risks getting a reputation as a problem employee or suffering workplace retaliation, according to Dr. Rohr-Kirchgraber. She recalls a colleague who was on a clinical education track until she lodged a harassment complaint. Abruptly, she was told she was needed on a service with fewer teaching opportunities.
With such risks in mind, respondents to the Medscape survey advised employees in medical workplaces to familiarize themselves with policies and procedures before pressing a case.
“Document everything,” an ophthalmologist urged, including time, place, offender, and witnesses. Present that information to your supervisor, and if nothing is done, hire a lawyer, a gastroenterologist suggested.
But taking the situation to the Equal Employment Opportunity Commission can be complicated, Roberta Gebhard, DO, past AMWA president and founder of its Gender Equity Task Force, told this news organization.
“They talk to the employer and get the employer’s side of the story and eventually render a decision about whether you have a case you can put through and file a lawsuit,” she said. “I don’t know of any other situation in which you need ‘permission’ to file a lawsuit.”
Nevertheless, an attorney can be helpful with cases, and when someone is terminated, a lawyer can possibly have it overturned or converted to a resignation, Dr. Gebhard said.
“And always have a lawyer review your contract before you take the job,” she advised. The lawyer might adjust the contract’s verbiage in ways that can protect one down the road in the event of a potential termination. “It’s money very well spent.”
More education needed
Dr. Rohr-Kirchgraber said that protection against harassment goes beyond the employer’s policies and procedures. Building an overall consciousness of what harassment is should begin with employee onboarding, she said.
“The harasser may not even recognize that what they’re doing or saying is a form of harassment, so we need better education,” Dr. Rohr-Kirchgraber emphasized.

Not testing VO2 max in your older patients? Here’s why you should
Once the focus of cyclists and other elite athletes, VO2 max has in recent years caught the attention of geriatricians, who have linked the measure to maximum functional capacity – an umbrella term for the body’s ability to perform aerobic exercise.
“Function is prognostic of mortality,” said Daniel E. Forman, MD, FAHA, FACC, professor of medicine and chair of the section of geriatric cardiology at the University of Pittsburgh Medical Center. “If you aren’t looking at that, you’re missing the boat.”
Although cardiopulmonary exercise testing (CPET) remains the gold standard for assessing VO2 max, Dr. Forman said clinicians often overlook CPET because it is old.
Getting precise
As a person ages, the amount of physical activity needed to stay fit varies, depending on genes, health, and fitness history. Measuring VO2 max can help doctors better prescribe physical activity, both with regard to specific exercises and for how long, Claudio Gil Araújo, MD, PhD, dean of research and education at the Exercise Medicine Clinic at CLINIMEX in Rio de Janeiro, Brazil, told this news organization. The test can also measure progress.
“Guidelines talk about how much exercise you should do every week, but it’s somewhat misleading because the health outcomes are much more linked to physical fitness than the amount of exercise you do,” Dr. Araújo said. Treating a patient with hypertension requires an individualized approach. “The same thing is true with exercise,” he said.
A person with high aerobic fitness, either because of favorable genetics or because he or she has maintained good fitness by exercising, may need less activity, but 200 minutes per week may not be enough for someone else.
In his own lab, Dr. Araújo is following “dozens” of men and women who have been able to increase their ability to exercise – especially high-intensity activity – over time. And their VO2 max readings have risen, he said.
Getting patients moving and collecting data on VO2 max is the most precise way to measure aerobic fitness. But the test is far from a staple in primary care.
Dr. Araújo said a growing body of research has long shown VO2 max to be a significant determinant of health and one that physicians should be paying closer attention to, especially for aging patients.
“If someone has a low VO2 max, the treatment to correct this unfavorable health profile is to increase exercise levels,” Dr. Araújo said. “This is a very relevant public health message.”
Investigators have found that inactivity increases a person’s risk of dying from an atherosclerotic cardiovascular disease event by about the same amount as smoking, and that a sedentary lifestyle increases with age . A patient’s fitness is crucial to his or her overall health, and VO2 max can play a key role. Poor performance on CPET could be a warning regarding a number of conditions, particularly cardiovascular and lung disease, Dr. Araújo said.
Indeed, acing the CPET is not easy.
“Your joints have to be normal, you can’t have low potassium, low sodium, or high blood sugar, your heart has to pump well, your blood vessels have to be healthy,” said Thomas Allison, PhD, MPH, director of the Integrated Stress Testing Center and the Sports Cardiology Clinic at Mayo Clinic, in Rochester, Minn. “All of those things can show up on the treadmill in terms of your VO2 max.”
Low VO2 max can be a physician’s first indication to investigate further. A review published in November 2022 in the International Journal of Cardiology Cardiovascular Risk and Prevention outlined what cross-sectional and longitudinal studies have documented regarding how VO2 max changes as people age. From ages 18 to 35, VO2 max remains fairly consistent. Between 35 and 55, it drops slightly but inexorably before falling sharply, if inconsistently. This inconsistency is where the important data lie.
“That lower level of physical activity may just be a behavioral change that needs to be reversed, or it could be a change that has been forced by underlying occult disease,” Dr. Allison said. That older people can’t run as fast as young people or are more likely to die in a given period than young people is not surprising. “The question is, at any given age, does your fitness level predict good health outcomes?” he said. “And the answer is yes.”
Fitness should be treated as any other data point, he added.
“If I want to know your blood pressure, I’m going to check your blood pressure; I’m not going to just ask you what it is,” Dr. Allison said. “If I ask if you have any limitations or symptoms with exercise or how physically active you are, if possible, I want to check that.”
Culture shift
Dr. Forman acknowledged that VO2 max tests can be difficult and expensive to administer in offices that aren’t already equipped with CPET machines. He said conducting other assessments, such as observing the patient performing a short walk, won’t provide as accurate data but is better than not assessing function at all.
“Specialists all have different things they measure, but function is the common denominator. For an aging population, it is the number one thing we should be looking at,” Dr. Forman said. “It’s a skill set, it’s an investment, it’s a change in culture at a time when cardiologists are obsessed with getting the latest imaging machines.”
Dr. Allison said all cardiologists should assess their patients’ VO2 max and that family medicine doctors should use the test for certain patients, such as those who have gained an unusual amount of weight or report being out of breath more than usual.
“We have all sorts of things that can go wrong with us as we get older, but if we’re sitting in a doctor’s office, it may not be apparent what they are,” Dr. Allison said. “We have to get patients up and moving.”
The authors have disclosed no relevant financial relationships.

Novel celery seed–derived drug may improve stroke outcomes
a new report suggests.
Patients treated with butylphthalide had fewer severe neurologic symptoms and better function 90 days after the stroke, compared with those receiving placebo.
Butylphthalide is approved and available for use in China, where the study was conducted. However, the medication hasn’t been approved for use by the U.S. Food and Drug Administration.
“Patients who received butylphthalide had less severe neurological symptoms and a better living status at 90 days post stroke, compared to those who received the placebo,” said coauthor Baixue Jia, MD, an attending physician in interventional neuroradiology at the Beijing Tiantan Hospital of Capital Medical University and a faculty member at the China National Clinical Research Center for Neurological Diseases in Beijing. “If the results are confirmed in other trials, this may lead to more options to treat strokes caused by clots.”
The study was presented at the International Stroke Conference presented by the American Stroke Association, a division of the American Heart Association.
Studying stroke outcomes
The researchers described butylphthalide as a cerebroprotective drug that was originally extracted from seeds of Apium graveolens. In China, previous studies have shown that the drug has cerebroprotective effects in animal models of ischemia-reperfusion, they noted.
In this randomized, double-blind, placebo-controlled trial, Dr. Jia and colleagues evaluated whether treatment with butylphthalide could improve 90-day outcomes for adults with acute ischemic stroke who received intravenous recombinant tissue plasminogen activator (tPA), endovascular treatment, or both.
The participants were treated at one of 59 medical centers in China between July 2018 and February 2022. Those who had minimal stroke symptoms on their initial exam, defined as a score of 0-3 on the National Institutes of Health Stroke Scale, or had severe stroke symptoms, defined as having a score of 26 or higher on the NIHSS, were excluded from the study.
Along with an initial revascularization intervention chosen by their physician, participants were randomly selected to receive either butylphthalide or a placebo daily for 90 days. The drug was administered through daily intravenous injections for the first 14 days, after which patients received oral capsules for 76 days.
The research team defined the outcomes as “favorable” if a patient fell into one of the following categories 90 days after the stroke: an initially mild to moderate stroke (NIHSS, 4-7) and no symptoms after treatment, defined as a score of 0 on the Modified Rankin Scale (mRS), which measures disability and dependence; an initially moderate to serious stroke (NIHSS, 8-14) and no residual symptoms or mild symptoms that don’t impair the ability to perform routine activities of daily living without assistance (mRS, 0-1); or an initially serious to severe stroke (NIHSS, 15-25) and no remaining symptoms or a slight disability that impairs some activities but allows one to conduct daily living without assistance (mRS, 0-2).
Secondary outcomes included symptomatic intracranial hemorrhage, recurrent stroke, and mortality.
Among the 1,216 participants, 607 were assigned to the treatment group, and 609 were assigned to the placebo group. The average age was 66 years, and 68% were men.
Overall, participants in the butylphthalide group were 70% more likely to have a favorable 90-day outcome, compared with the placebo group. Favorable outcomes occurred in 344 patients (56.7%) in the butylphthalide group, compared with 268 patients (44%) in the placebo group (odds ratio, 1.70; 95% confidence interval, 1.35-2.14; P < .001).
In addition, butylphthalide improved function equally well for the patients who initially received tPA, those who received endovascular treatment, and those who received both tPA and endovascular treatment.
Secondary events, such as recurrent stroke and intracranial hemorrhage, weren’t significantly different between the butylphthalide and placebo groups.
Ongoing questions
Dr. Jia and colleagues noted the need to understand how butylphthalide works in the brain. Animal studies have suggested several possible mechanisms, but it remains unclear.
“The next step should be investigating the exact mechanisms of butylphthalide in humans,” Dr. Jia said.
Additional research should assess the medication in other populations, the authors noted, particularly because the study involved participants who received initial treatment with tPA, endovascular treatment, or both. The results may not be generalizable to stroke patients who receive other treatments or to populations outside of China.
“While these are interesting results, this is only one relatively small study on a fairly select population in China. Butylphthalide, a medication initially compounded from celery seed, is not ready for use in standard stroke treatment,” said Daniel Lackland, DrPH, professor of neurology and director of the division of translational neurosciences and population studies at the Medical University of South Carolina, Charleston.
Dr. Lackland, who wasn’t involved with the study, is a member of the American Stroke Association’s Stroke Council. Although butylphthalide was originally extracted from seeds, he noted, it’s not what patients would find commercially available.
“The medication used in this study is not the same as celery seed or celery seed extract supplements,” he said. “Stroke survivors should always consult with their neurologist or healthcare professional regarding diet after a stroke.”

a new report suggests.
Patients treated with butylphthalide had fewer severe neurologic symptoms and better function 90 days after the stroke, compared with those receiving placebo.
Butylphthalide is approved and available for use in China, where the study was conducted. However, the medication hasn’t been approved for use by the U.S. Food and Drug Administration.
“Patients who received butylphthalide had less severe neurological symptoms and a better living status at 90 days post stroke, compared to those who received the placebo,” said coauthor Baixue Jia, MD, an attending physician in interventional neuroradiology at the Beijing Tiantan Hospital of Capital Medical University and a faculty member at the China National Clinical Research Center for Neurological Diseases in Beijing. “If the results are confirmed in other trials, this may lead to more options to treat strokes caused by clots.”
The study was presented at the International Stroke Conference presented by the American Stroke Association, a division of the American Heart Association.
Studying stroke outcomes
The researchers described butylphthalide as a cerebroprotective drug that was originally extracted from seeds of Apium graveolens. In China, previous studies have shown that the drug has cerebroprotective effects in animal models of ischemia-reperfusion, they noted.
In this randomized, double-blind, placebo-controlled trial, Dr. Jia and colleagues evaluated whether treatment with butylphthalide could improve 90-day outcomes for adults with acute ischemic stroke who received intravenous recombinant tissue plasminogen activator (tPA), endovascular treatment, or both.
The participants were treated at one of 59 medical centers in China between July 2018 and February 2022. Those who had minimal stroke symptoms on their initial exam, defined as a score of 0-3 on the National Institutes of Health Stroke Scale, or had severe stroke symptoms, defined as having a score of 26 or higher on the NIHSS, were excluded from the study.
Along with an initial revascularization intervention chosen by their physician, participants were randomly selected to receive either butylphthalide or a placebo daily for 90 days. The drug was administered through daily intravenous injections for the first 14 days, after which patients received oral capsules for 76 days.
The research team defined the outcomes as “favorable” if a patient fell into one of the following categories 90 days after the stroke: an initially mild to moderate stroke (NIHSS, 4-7) and no symptoms after treatment, defined as a score of 0 on the Modified Rankin Scale (mRS), which measures disability and dependence; an initially moderate to serious stroke (NIHSS, 8-14) and no residual symptoms or mild symptoms that don’t impair the ability to perform routine activities of daily living without assistance (mRS, 0-1); or an initially serious to severe stroke (NIHSS, 15-25) and no remaining symptoms or a slight disability that impairs some activities but allows one to conduct daily living without assistance (mRS, 0-2).
Secondary outcomes included symptomatic intracranial hemorrhage, recurrent stroke, and mortality.
Among the 1,216 participants, 607 were assigned to the treatment group, and 609 were assigned to the placebo group. The average age was 66 years, and 68% were men.
Overall, participants in the butylphthalide group were 70% more likely to have a favorable 90-day outcome, compared with the placebo group. Favorable outcomes occurred in 344 patients (56.7%) in the butylphthalide group, compared with 268 patients (44%) in the placebo group (odds ratio, 1.70; 95% confidence interval, 1.35-2.14; P < .001).
In addition, butylphthalide improved function equally well for the patients who initially received tPA, those who received endovascular treatment, and those who received both tPA and endovascular treatment.
Secondary events, such as recurrent stroke and intracranial hemorrhage, weren’t significantly different between the butylphthalide and placebo groups.
Ongoing questions
Dr. Jia and colleagues noted the need to understand how butylphthalide works in the brain. Animal studies have suggested several possible mechanisms, but it remains unclear.
“The next step should be investigating the exact mechanisms of butylphthalide in humans,” Dr. Jia said.
Additional research should assess the medication in other populations, the authors noted, particularly because the study involved participants who received initial treatment with tPA, endovascular treatment, or both. The results may not be generalizable to stroke patients who receive other treatments or to populations outside of China.
“While these are interesting results, this is only one relatively small study on a fairly select population in China. Butylphthalide, a medication initially compounded from celery seed, is not ready for use in standard stroke treatment,” said Daniel Lackland, DrPH, professor of neurology and director of the division of translational neurosciences and population studies at the Medical University of South Carolina, Charleston.
Dr. Lackland, who wasn’t involved with the study, is a member of the American Stroke Association’s Stroke Council. Although butylphthalide was originally extracted from seeds, he noted, it’s not what patients would find commercially available.
“The medication used in this study is not the same as celery seed or celery seed extract supplements,” he said. “Stroke survivors should always consult with their neurologist or healthcare professional regarding diet after a stroke.”

What’s new in brain health?
This transcript has been edited for clarity.
Dear colleagues, I am Christoph Diener from the medical faculty of the University of Duisburg-Essen in Germany.
Treatment of tension-type headache
I would like to start with headache. You are all aware that we have several new studies regarding the prevention of migraine, but very few studies involving nondrug treatments for tension-type headache.
A working group in Göttingen, Germany, conducted a study in people with frequent episodic and chronic tension-type headache. The first of the four randomized groups received traditional Chinese acupuncture for 3 months. The second group received physical therapy and exercise for 1 hour per week for 12 weeks. The third group received a combination of acupuncture and exercise. The last was a control group that received only standard care.
The outcome parameters of tension-type headache were evaluated after 6 months and again after 12 months. Previously, these same researchers published that the intensity but not the frequency of tension-type headache was reduced by active therapy.
In Cephalalgia, they published the outcome for the endpoints of depression, anxiety, and quality of life. Acupuncture, exercise, and the combination of the two improved depression, anxiety, and quality of life. This shows that nonmedical treatment is effective in people with frequent episodic and chronic tension-type headache.
Headache after COVID-19
The next study was published in Headache and discusses headache after COVID-19. In this review of published studies, more than 50% of people with COVID-19 develop headache. It is more frequent in young patients and people with preexisting primary headaches, such as migraine and tension-type headache. Prognosis is usually good, but some patients develop new, daily persistent headache, which is a major problem because treatment is unclear. We desperately need studies investigating how to treat this new, daily persistent headache after COVID-19.
SSRIs during COVID-19 infection
The next study also focuses on COVID-19. We have conflicting results from several studies suggesting that selective serotonin reuptake inhibitors might be effective in people with mild COVID-19 infection. This hypothesis was tested in a study in Brazil and was published in JAMA, The study included 1,288 outpatients with mild COVID-19 who either received 50 mg of fluvoxamine twice daily for 10 days or placebo. There was no benefit of the treatment for any outcome.
Preventing dementia with antihypertensive treatment
The next study was published in the European Heart Journal and addresses the question of whether effective antihypertensive treatment in elderly persons can prevent dementia. This is a meta-analysis of five placebo-controlled trials with more than 28,000 patients. The meta-analysis clearly shows that treating hypertension in elderly patients does prevent dementia. The benefit is higher if the blood pressure is lowered by a larger amount which also stays true for elderly patients. There is no negative impact of lowering blood pressure in this population.
Antiplatelet therapy
The next study was published in Stroke and reexamines whether resumption of antiplatelet therapy should be early or late in people who had an intracerebral hemorrhage while on antiplatelet therapy. In the Taiwanese Health Registry, this was studied in 1,584 patients. The researchers divided participants into groups based on whether antiplatelet therapy was resumed within 30 days or after 30 days. In 1 year, the rate of recurrent intracerebral hemorrhage was 3.2%. There was no difference whether antiplatelet therapy was resumed early or late.
Regular exercise in Parkinson’s disease
The final study is a review of nonmedical therapy. This meta-analysis of 19 randomized trials looked at the benefit of regular exercise in patients with Parkinson’s disease and depression. The analysis clearly showed that rigorous and moderate exercise improved depression in patients with Parkinson’s disease. This is very important because exercise improves not only the symptoms of Parkinson’s disease but also comorbid depression while presenting no serious adverse events or side effects.

A doctor must go to extremes to save a choking victim
Some time ago I was invited to join a bipartisan congressional task force on valley fever, also known as coccidioidomycosis. A large and diverse crowd attended the task force’s first meeting in Bakersfield, Calif. – a meeting for everyone: the medical profession, the public, it even included veterinarians.
The whole thing was a resounding success. Francis Collins was there, the just-retired director of the NIH. Tom Frieden, then-director of the Centers for Disease Control and Prevention was there, as were several congresspeople and also my college roommate, a retired Navy medical corps captain. I was enjoying it.
Afterward, we had a banquet dinner at a restaurant in downtown Bakersfield. One of the people there was a woman I knew well – her husband was a physician friend. The restaurant served steak and salmon, and this woman made the mistake of ordering the steak.
Not long after the entrees were served, I heard a commotion at the table just behind me. I turned around and saw that woman in distress. A piece of steak had wedged in her trachea and she couldn’t breathe.
Almost immediately, the chef showed up. I don’t know how he got there. The chef at this restaurant was a big guy. I mean, probably 6 feet, 5 inches tall and 275 pounds. He tried the Heimlich maneuver. It didn’t work.
At that point, I jumped up. I thought, “Well, maybe I know how to do this better than him.” Probably not, actually. I tried and couldn’t make it work either. So I knew we were going to have to do something.
Paul Krogstad, my friend and research partner who is a pediatric infectious disease physician, stepped up and tried to put his finger in her throat and dig it out. He couldn’t get it. The patient had lost consciousness.
So, I’m thinking, okay, there’s really only one choice. You have to get an airway surgically.
I said, “We have to put her down on the floor.” And then I said, “Knife!”
I was looking at the steak knives on the table and they weren’t to my liking for doing a procedure. My college roommate – the retired Navy man – whipped out this very good pocketknife.
I had never done this in my life.
While I was making the incision, somebody gave Paul a ballpoint pen and he broke it into pieces to make a tracheostomy tube. Once I’d made the little incision, I put the tube in. She wasn’t breathing, but she still had a pulse.
I leaned forward and blew into the tube and inflated her lungs. I could see her lungs balloon up. It was a nice feeling, because I knew I was clearly in the right place.
I can’t quite explain it, but while I was doing this, I was enormously calm and totally focused. I knew there was a crowd of people around me, all looking at me, but I wasn’t conscious of that.
It was really just the four of us: Paul and Tom and me and our patient. Those were the only people that I was really cognizant of. Paul and Tom were not panic stricken at all. I remember somebody shouting, “We have to start CPR!” and Frieden said, “No. We don’t.”
Moments later, she woke up, sat up, coughed, and shot the piece of steak across the room.
She was breathing on her own, but we still taped that tube into place. Somebody had already summoned an ambulance; they were there not very long after we completed this procedure. I got in the ambulance with her and we rode over to the emergency room at Mercy Truxtun.
She was stable and doing okay. I sat with her until a thoracic surgeon showed up. He checked out the situation and decided we didn’t need that tube and took it out. I didn’t want to take that out until I had a surgeon there who could do a formal tracheostomy.
They kept her in the hospital for 3 or 4 days. Now, this woman had always had difficulties swallowing, so steak may not have been the best choice. She still had trouble swallowing afterward but recovered.
I’ve known her and her husband a long time, so it was certainly rewarding to be able to provide this service. Years later, though, when her husband died, I spoke at his funeral. When she was speaking to the gathering, she said, “And oh, by the way, Royce, thanks for saving my life.”
That surprised me. I didn’t think we were going to go there.
I’d never tried to practice medicine “at the roadside” before. But that’s part of the career.

I leaned forward and blew into the tube and inflated her lungs. I could see her lungs balloon up. It was a nice feeling, because I knew I was clearly in the right place.
I can’t quite explain it, but while I was doing this, I was enormously calm and totally focused. I knew there was a crowd of people around me, all looking at me, but I wasn’t conscious of that.
It was really just the four of us: Paul and Tom and me and our patient. Those were the only people that I was really cognizant of. Paul and Tom were not panic stricken at all. I remember somebody shouting, “We have to start CPR!” and Frieden said, “No. We don’t.”
Moments later, she woke up, sat up, coughed, and shot the piece of steak across the room.
She was breathing on her own, but we still taped that tube into place. Somebody had already summoned an ambulance; they were there not very long after we completed this procedure. I got in the ambulance with her and we rode over to the emergency room at Mercy Truxtun.
She was stable and doing okay. I sat with her until a thoracic surgeon showed up. He checked out the situation and decided we didn’t need that tube and took it out. I didn’t want to take that out until I had a surgeon there who could do a formal tracheostomy.
They kept her in the hospital for 3 or 4 days. Now, this woman had always had difficulties swallowing, so steak may not have been the best choice. She still had trouble swallowing afterward but recovered.
I’ve known her and her husband a long time, so it was certainly rewarding to be able to provide this service. Years later, though, when her husband died, I spoke at his funeral. When she was speaking to the gathering, she said, “And oh, by the way, Royce, thanks for saving my life.”
That surprised me. I didn’t think we were going to go there.
I’d never tried to practice medicine “at the roadside” before. But that’s part of the career.

Some time ago I was invited to join a bipartisan congressional task force on valley fever, also known as coccidioidomycosis. A large and diverse crowd attended the task force’s first meeting in Bakersfield, Calif. – a meeting for everyone: the medical profession, the public, it even included veterinarians.
The whole thing was a resounding success. Francis Collins was there, the just-retired director of the NIH. Tom Frieden, then-director of the Centers for Disease Control and Prevention was there, as were several congresspeople and also my college roommate, a retired Navy medical corps captain. I was enjoying it.
Afterward, we had a banquet dinner at a restaurant in downtown Bakersfield. One of the people there was a woman I knew well – her husband was a physician friend. The restaurant served steak and salmon, and this woman made the mistake of ordering the steak.
Not long after the entrees were served, I heard a commotion at the table just behind me. I turned around and saw that woman in distress. A piece of steak had wedged in her trachea and she couldn’t breathe.
Almost immediately, the chef showed up. I don’t know how he got there. The chef at this restaurant was a big guy. I mean, probably 6 feet, 5 inches tall and 275 pounds. He tried the Heimlich maneuver. It didn’t work.
At that point, I jumped up. I thought, “Well, maybe I know how to do this better than him.” Probably not, actually. I tried and couldn’t make it work either. So I knew we were going to have to do something.
Paul Krogstad, my friend and research partner who is a pediatric infectious disease physician, stepped up and tried to put his finger in her throat and dig it out. He couldn’t get it. The patient had lost consciousness.
So, I’m thinking, okay, there’s really only one choice. You have to get an airway surgically.
I said, “We have to put her down on the floor.” And then I said, “Knife!”
I was looking at the steak knives on the table and they weren’t to my liking for doing a procedure. My college roommate – the retired Navy man – whipped out this very good pocketknife.
I had never done this in my life.
While I was making the incision, somebody gave Paul a ballpoint pen and he broke it into pieces to make a tracheostomy tube. Once I’d made the little incision, I put the tube in. She wasn’t breathing, but she still had a pulse.

New tool better estimates cardiovascular risk in people with lupus
Current risk estimators are inaccurate
A tool that incorporates lupus-related variables with traditional risk factors provides a much more accurate assessment of cardiovascular (CV) risk in patients with systemic lupus erythematosus (SLE), according to data presented at the annual meeting of the Canadian Rheumatology Association.
In the initial clinical assessment of this tool, called the SLECRISK, “it identified high-risk lupus patients who would otherwise be missed by traditional methods of CV risk assessment,” reported May Y. Choi, MD, associate director of translational research at the University of Calgary’s (Alta.) Lupus Centre of Excellence.
It is well known that patients with SLE face an increased risk of CV events starting at an age long before risk begins climbing in the general population, according to Dr. Choi. She cited one study that showed women aged 35-44 years have a 50-fold greater risk of myocardial infarction than healthy individuals.
All major guidelines recognize this increased risk and recommend CV risk assessment in patients with SLE, even though Dr. Choi pointed out that traditional tools, such as the American College of Cardiology atherosclerotic cardiovascular disease (ASCVD) risk calculator or the Framingham Risk Score (FRS) have a limited ability to detect the patients with SLE who are most likely to have an event.
In SLE, current tools are inadequate
“These risk assessment tools perform poorly in SLE patients because they do not capture SLE-related inflammation,” Dr. Choi said. Of several examples, Dr. Choi cited a study showing “seven times more MIs and strokes observed than expected in SLE patients on the basis of the FRS.”
The disparity between expected and observed MIs and strokes is worse with increasing severity of SLE. In a study she presented 3 years ago, rates of CV events were 12 times higher in those with inactive or mild SLE, rising to a 16-fold increase among those with moderate disease and jumping to a 32-fold increase in those with severe SLE.
The SLECRISK tool was developed from the Brigham and Women’s Hospital SLE Registry, which was initiated in 1992. Patients without a history of CV disease were evaluated for traditional CV risk factors and for SLE-specific characteristics such as disease activity, levels of the complement proteins C3 and C4, kidney function, the presence of nephritis, and SLE duration. The value of these characteristics as predictors of CV events were then assessed over a 10-year follow-up period before being assembled into the SLECRISK tool.
In an example of the risk equation, Dr. Choi described a 50-year-old patient with SLE and a 5% 10-year ASCVD risk score, which is low. After adjustment for SLE risks, which included 10 years disease duration, high disease activity, elevated creatinine, and positive anti–double stranded DNA status, the 10-year CV risk score climbed to 16.2%, which is moderate.
The performance of the SLECRISK was evaluated in 1,243 patients providing 8,946.51 person-years of follow-up. During this period, there were 90 major adverse cardiac events (MACE), of which 82% were adjudicated by cardiologists, and 211 secondary events.
Relative to the ASCVD risk score, the SLECRISK identified about twice as many patients with SLE as having moderate risk and 3.5-fold more patients as having high risk. Among patients who experienced CV events, traditional CV risk factors were more common but so were SLE-specific risk factors, including greater disease severity, a greater likelihood of lupus nephritis, increased complement levels, and greater exposure to glucocorticoids, according to Dr. Choi.
Specificities for CV events higher on SLECRISK
In predicting CV events, the differences in specificities were in the same general range, although somewhat higher for the ASCVD risk score in regard to predicting MACE (83% vs. 72%) and MACE plus secondary events (90% vs. 79%). However, the sensitivities were much higher for SLECRISK relative to the ASCVD risk score for MACE alone (64% vs. 41%) and for MACE plus secondary events (58% vs. 35%).
When comparing those who had an MI or stroke, the ASCVD risk score identified 8 (7%) patients missed by SLECRISK, whereas SLECRISK identified 89 (73%) missed by the ASCVD risk score. The remaining 25 patients (20%) were identified by both. The advantage of SLECRISK was similar for MACE plus secondary outcomes.
Dr. Choi noted that all of the SLE-specific variables in SLECRISK are readily obtained and often already available in patient charts. She said that there is a plan to validate the tool in larger groups, but with a goal of creating a tool available online for clinicians and their patients to use. There is also an even more ambitious plan for the future.
“We have funding to look at machine learning to evaluate predictive variables in SLE patients,” Dr. Choi said. Rather than adding SLE-specific variables to traditional risks, the plan is to “start from scratch,” letting artificial intelligence assemble predictors without prejudice to what might or might not be relevant.
A SLE-specific tool for evaluating CV risk is an important “unmet need,” according to Karen H. Costenbader, MD, professor in the division of rheumatology, inflammation, and immunity at Brigham and Women’s Hospital and Harvard Medical School, both in Boston. In an interview, she reiterated that measuring CV risk in SLE is already guideline recommended, but conventional tools have been shown to be inaccurate.
“I can envision it being used in clinical encounters to help guide shared decision-making with patients,” explained Dr. Costenbader, who was not involved in the presentation at the CRA meeting but worked with Dr. Choi in developing SLECRISK. “It would give us more precise estimates, allowing us to risk stratify our patients and informing us as to which modifiable SLE-specific and nonspecific factors are contributing most to CV risk.’
The problem of using conventional risk assessments in SLE has been well recognized. Of those who have written on this subject, Maureen McMahon, MD, site director of the Lupus Clinical Trials Network at the University of California, Los Angeles, said: “There is a critical need for the development of SLE-specific risk assessment tools like SLECRISK.”
Author of several studies looking at alternatives for CV risk assessment in SLE, including a study looking at a panel of biomarkers that was published in ACR Open Rheumatology, Dr. McMahon said in an interview that CV risk in SLE is high but conventional risk assessments are flawed.
“Multiple previous studies have demonstrated that these currently available calculators are not adequate for identifying risk in the lupus patient population,” she said. According to Dr. McMahon, the fact that rheumatologists remain “dependent upon [these conventional] cardiovascular risk calculators” is a well-recognized problem that needs resolution.
Dr. Choi has financial relationships with AstraZeneca, GlaxoSmithKline, Mallinckrodt. MitogenDx, Organon, and Werfen International. Dr. Costenbader reports no potential conflicts of interest. Dr. McMahon has financial relationships with AstraZeneca, Aurinia Pharmaceuticals, Eli Lilly, and GlaxoSmithKline.

Drug combo promising in vascular cognitive impairment: LACI-2 trial results
and is seen as a new therapeutic approach for patients with cerebral small-vessel disease. The drugs – isosorbide mononitrate and cilostazol – stabilize endothelial function, which is a new therapeutic target for patients with small-vessel disease stroke.
The phase 2 LACI-2 study, evaluating these drugs individually and in combination in patients with lacunar stroke, showed promising trends toward reductions in recurrent stroke, cognitive impairment, and dependency, some of which became significant when the drugs were given together. There was also some suggestion of positive impacts on mood and quality of life.
“Isosorbide mononitrate was associated with a reduction in recurrent stroke, a tendency toward a reduction in dependency and a reduction in cognitive impairment, and cilostazol also seemed to reduce dependency,” study investigator Joanna M. Wardlaw, MD, professor of applied neuroimaging at Edinburgh University, reported.
“When used together, they seemed to have more benefits than either drug on its own. So this is good preliminary evidence that the drugs are working together in a positive way,” she said. But she cautioned that these potential benefits will need to be confirmed in a larger phase 3 trial.
The LACI-2 study was presented at the International Stroke Conference by Dr. Wardlaw and coinvestigator Philip Bath, DSc, professor of medicine at the University of Nottingham (England).
They both highlighted the effect seen on cognitive impairment at the conference presented by the American Stroke Association, a division of the American Heart Association.
“We saw a significant reduction in the number of patients with cognitive impairment with the two drugs together in this phase 2 study,” Dr. Wardlaw said. “This is very encouraging since no study has previously found any medications that positively affect cognitive impairment in small-vessel disease strokes. We cautiously hope that these medications may have wider implications for other types of small-vessel disease as well.”
Dr. Bath added: “The results on cognitive impairment are particularly important. Many patients rate cognitive impairment as one of the most dreaded outcomes of a stroke even if they also have quite significant physical disability. People simply don’t want to lose their memory and thinking ability.”
“The results of LACI-2 also raise interesting questions about whether these drugs would be beneficial for other types of small-vessel disease which do not present as stroke, but maybe may manifest as headaches or memory impairment,” he noted.
‘Very intriguing results’
Outside experts were enthusiastic about these preliminary results. In an ISC highlights presentation, program chair Tudor Jovin, MD, Cooper Neurological Institute, Cherry Hill, N.J., said: “It is refreshing to finally see some positive signals in studies in small-vessel stroke. This is an area where we haven’t had answers for a long time.”
He described the reduction in cognitive impairment seen in the study as “very intriguing and very important.”
“I think we have underestimated the burden that cognitive impairment has in stroke, and the burden in general in society of vascular cognitive impairment. This is a very promising approach that definitely deserves to be investigated more thoroughly in a larger trial.”
Commenting on the study findings, Mitchell Elkind, MD, professor of neurology and epidemiology at Columbia University Irving Medical Center, New York, said this study “provides evidence that points us in at least two important directions.”
“First, it suggests that endothelial dysfunction, or problems with the lining of the blood vessels, may be an important contributor to small-vessel disease and the cognitive decline that often accompanies it. This is a new mechanism of action and different from blood clotting, blood pressure, and other conventional targets of treatment,” Dr. Elkind said.
“Second, and more generally, it suggests that stroke trials, particularly in the subtype of small-vessel disease, can and should explore not only the incidence of recurrent acute events but also the steady decline that occurs after stroke. Poststroke cognitive decline is a relatively new area of stroke research.”
Dr. Wardlaw noted that lacunar stroke is a common type of ischemic stroke, but it has been rather neglected in terms of research. It is assumed to be caused by atherosclerosis of the small vessel but there is now mounting evidence suggesting that it is a result of problems in the endothelium of the small vessels.
“We looked for potential available drugs that targeted endothelial dysfunction. Both the drugs we tested are already widely used – isosorbide mononitrate for the treatment of coronary artery disease and angina, and cilostazol, mainly in Asia, for stroke prevention,” she said.
LACI-2 was primarily a feasibility study looking at whether it was possible to recruit enough patients who had had a lacunar stroke and would take the drugs, individually or in combination, for up to a year. Outcomes were investigated on an exploratory basis. The study enrolled 363 patients who had experienced lacunar stroke from 26 stroke centers throughout the United Kingdom. They were randomly assigned to one of four treatment groups for 1 year:
- 40-60 mg/day of oral isosorbide mononitrate alone.
- 200 mg/day of oral cilostazol alone.
- Both medications.
- Neither medication.
Patients completed phone surveys at 6 and 12 months to assess health status, including recurrent stroke, myocardial infarction, cognitive tests, symptoms, quality of life surveys, and they also had brain imaging at 12 months.
Results showed 98% of patients were still taking their study medication at 1 year, and the drugs appeared to be safe on top of usual care with few deaths or hemorrhages in the study.
The composite outcome including recurrent stroke, MI, cognitive impairment, dependency (modified Rankin score > 2) and death was reduced by 20% in the isosorbide mononitrate–alone group (adjusted hazard ratio, 0.80; 95% confidence interval, 0.59-1.09).
The composite endpoint was reduced by 23% in the cilostazol group (aHR, 0.77; 95% CI, 0.57-1.05) and by 42% in the combination group (aHR, 0.58, 95% CI, 0.36-0.92) compared with those taking neither drug.
Isosorbide mononitrate alone showed trends toward a reduction in recurrent stroke, cognitive impairment, and dependency, whereas cilostazol alone reduced dependency with a trend toward a reduction in cognitive impairment. When used together, the drugs showed large reductions in cognitive impairment (aHR, 0.44; 95% CI, 0.19-0.99) and dependency (aHR ,0.14; 95% CI, 0.03-0.59).
During the highlights session, Dr. Jovin commented: “It is obvious that the investigators have put a lot of thought into the design of this trial. Presumably because of the composite score they were able to increase the power. We are used to trials which require thousands of patients, but here we are able to see significant results, although exploratory, with just a few hundred patients.”
Dr. Bath stressed that this was only a phase 2 study. “We now need to see if we can confirm these results in a larger phase 3 study.” That study, LACI-3, is planned to start later this year. He also suggested that it would be interesting to investigate whether these drugs would work in other types of ischemic stroke such as those caused by large-artery disease or cardioembolic strokes, as well as other forms of small-vessel disease such as patients with vascular cognitive impairment.
“There are many areas to investigate in future. It might be that in a few years’ time these drugs may be standard of care across many different forms of small-vessel disease,” he said.
Dr. Wardlaw noted that lacunar strokes are generally quite mild strokes, which could be one of the reasons why they have not been the target of much research to date. But Dr. Bath added: “While they may be labeled as a mild stroke on the NIHSS scale, patients can still be quite badly affected. About half of patients with a lacunar stroke develop cognitive impairment and eventually dementia – that is certainly not mild.”

and is seen as a new therapeutic approach for patients with cerebral small-vessel disease. The drugs – isosorbide mononitrate and cilostazol – stabilize endothelial function, which is a new therapeutic target for patients with small-vessel disease stroke.
The phase 2 LACI-2 study, evaluating these drugs individually and in combination in patients with lacunar stroke, showed promising trends toward reductions in recurrent stroke, cognitive impairment, and dependency, some of which became significant when the drugs were given together. There was also some suggestion of positive impacts on mood and quality of life.
“Isosorbide mononitrate was associated with a reduction in recurrent stroke, a tendency toward a reduction in dependency and a reduction in cognitive impairment, and cilostazol also seemed to reduce dependency,” study investigator Joanna M. Wardlaw, MD, professor of applied neuroimaging at Edinburgh University, reported.
“When used together, they seemed to have more benefits than either drug on its own. So this is good preliminary evidence that the drugs are working together in a positive way,” she said. But she cautioned that these potential benefits will need to be confirmed in a larger phase 3 trial.
The LACI-2 study was presented at the International Stroke Conference by Dr. Wardlaw and coinvestigator Philip Bath, DSc, professor of medicine at the University of Nottingham (England).
They both highlighted the effect seen on cognitive impairment at the conference presented by the American Stroke Association, a division of the American Heart Association.
“We saw a significant reduction in the number of patients with cognitive impairment with the two drugs together in this phase 2 study,” Dr. Wardlaw said. “This is very encouraging since no study has previously found any medications that positively affect cognitive impairment in small-vessel disease strokes. We cautiously hope that these medications may have wider implications for other types of small-vessel disease as well.”
Dr. Bath added: “The results on cognitive impairment are particularly important. Many patients rate cognitive impairment as one of the most dreaded outcomes of a stroke even if they also have quite significant physical disability. People simply don’t want to lose their memory and thinking ability.”
“The results of LACI-2 also raise interesting questions about whether these drugs would be beneficial for other types of small-vessel disease which do not present as stroke, but maybe may manifest as headaches or memory impairment,” he noted.
‘Very intriguing results’
Outside experts were enthusiastic about these preliminary results. In an ISC highlights presentation, program chair Tudor Jovin, MD, Cooper Neurological Institute, Cherry Hill, N.J., said: “It is refreshing to finally see some positive signals in studies in small-vessel stroke. This is an area where we haven’t had answers for a long time.”
He described the reduction in cognitive impairment seen in the study as “very intriguing and very important.”
“I think we have underestimated the burden that cognitive impairment has in stroke, and the burden in general in society of vascular cognitive impairment. This is a very promising approach that definitely deserves to be investigated more thoroughly in a larger trial.”
Commenting on the study findings, Mitchell Elkind, MD, professor of neurology and epidemiology at Columbia University Irving Medical Center, New York, said this study “provides evidence that points us in at least two important directions.”
“First, it suggests that endothelial dysfunction, or problems with the lining of the blood vessels, may be an important contributor to small-vessel disease and the cognitive decline that often accompanies it. This is a new mechanism of action and different from blood clotting, blood pressure, and other conventional targets of treatment,” Dr. Elkind said.
“Second, and more generally, it suggests that stroke trials, particularly in the subtype of small-vessel disease, can and should explore not only the incidence of recurrent acute events but also the steady decline that occurs after stroke. Poststroke cognitive decline is a relatively new area of stroke research.”
Dr. Wardlaw noted that lacunar stroke is a common type of ischemic stroke, but it has been rather neglected in terms of research. It is assumed to be caused by atherosclerosis of the small vessel but there is now mounting evidence suggesting that it is a result of problems in the endothelium of the small vessels.
“We looked for potential available drugs that targeted endothelial dysfunction. Both the drugs we tested are already widely used – isosorbide mononitrate for the treatment of coronary artery disease and angina, and cilostazol, mainly in Asia, for stroke prevention,” she said.
LACI-2 was primarily a feasibility study looking at whether it was possible to recruit enough patients who had had a lacunar stroke and would take the drugs, individually or in combination, for up to a year. Outcomes were investigated on an exploratory basis. The study enrolled 363 patients who had experienced lacunar stroke from 26 stroke centers throughout the United Kingdom. They were randomly assigned to one of four treatment groups for 1 year:
- 40-60 mg/day of oral isosorbide mononitrate alone.
- 200 mg/day of oral cilostazol alone.
- Both medications.
- Neither medication.
Patients completed phone surveys at 6 and 12 months to assess health status, including recurrent stroke, myocardial infarction, cognitive tests, symptoms, quality of life surveys, and they also had brain imaging at 12 months.
Results showed 98% of patients were still taking their study medication at 1 year, and the drugs appeared to be safe on top of usual care with few deaths or hemorrhages in the study.
The composite outcome including recurrent stroke, MI, cognitive impairment, dependency (modified Rankin score > 2) and death was reduced by 20% in the isosorbide mononitrate–alone group (adjusted hazard ratio, 0.80; 95% confidence interval, 0.59-1.09).
The composite endpoint was reduced by 23% in the cilostazol group (aHR, 0.77; 95% CI, 0.57-1.05) and by 42% in the combination group (aHR, 0.58, 95% CI, 0.36-0.92) compared with those taking neither drug.
Isosorbide mononitrate alone showed trends toward a reduction in recurrent stroke, cognitive impairment, and dependency, whereas cilostazol alone reduced dependency with a trend toward a reduction in cognitive impairment. When used together, the drugs showed large reductions in cognitive impairment (aHR, 0.44; 95% CI, 0.19-0.99) and dependency (aHR ,0.14; 95% CI, 0.03-0.59).
During the highlights session, Dr. Jovin commented: “It is obvious that the investigators have put a lot of thought into the design of this trial. Presumably because of the composite score they were able to increase the power. We are used to trials which require thousands of patients, but here we are able to see significant results, although exploratory, with just a few hundred patients.”
Dr. Bath stressed that this was only a phase 2 study. “We now need to see if we can confirm these results in a larger phase 3 study.” That study, LACI-3, is planned to start later this year. He also suggested that it would be interesting to investigate whether these drugs would work in other types of ischemic stroke such as those caused by large-artery disease or cardioembolic strokes, as well as other forms of small-vessel disease such as patients with vascular cognitive impairment.

Tenecteplase noninferior to alteplase for ischemic stroke: TRACE-2
, a new study has found. “This was a pivotal trial in establishing the safety and efficacy of tenecteplase as an alternative to alteplase in the thrombolytic treatment of acute ischemic stroke within 4.5 hours in Asian patients,” said study author Shuya Li, MD, associate chief physician, department of neurology, Beijing Tiantan Hospital, Capital Medical University, Beijing.
The findings in this all-Chinese population should have an impact on the use of tenecteplase going forward, said Dr. Li. “The results provide further evidence to support a worldwide switch to tenecteplase as the preferred thrombolytic for acute ischemic stroke.”
The findings were presented at the 2023 International Stroke Conference presented by the American Stroke Association, a division of the American Heart Association.
Single bolus
Use of alteplase (tissue plasminogen activator [tPA]) has for years been the main approach to thrombolytic reperfusion therapy for patients with acute stroke, but tenecteplase has recently emerged as a potential successor.
Tenecteplase is a tPA produced by recombinant DNA technology. It has a relatively long half-life and can be delivered in a single bolus instead of requiring an hour-long infusion, as is the case with alteplase.
The phase 3 noninferiority Tenecteplase Reperfusion Therapy in Acute ischemic Cerebrovascular Events (TRACE-2) trial – the first of its kind in an Asian population – included 1,430 adult ischemic stroke patients at 53 Chinese centers. Patients had to have a National Institutes of Health Stroke Scale (NIHSS) score of 5-25 and either not be eligible for or have refused endovascular therapy.
The mean age of study participants was about 66 years, and the percentage of women was about 31%. The mean baseline NIHSS score was 7 in both groups, and the symptom-onset-to-needle time was similar at 180 minutes for the tenecteplase group and 178.5 minutes for the alteplase group.
Researchers randomly assigned patients to receive tenecteplase or alteplase within 4.5 hours of symptom onset.
Those in the tenecteplase group received 0.25 mg/kg of the drug in a single IV bolus (maximum dose, 25 mg). Control group members who were treated with alteplase were given the drug as a 10% bolus, with the remainder given as a 1-hour infusion (0.9 mg/kg with a maximum dose of 90 mg).
Showed noninferiority
The primary efficacy outcome was a modified Rankins scale (mRS) score of 0-1 at 90 days, which is considered excellent function. About 62% of tenecteplase patients and 58% of alteplase patients attained this outcome (risk ratio, 1.09; 95% confidence interval, 1.00-1.18).
The P value was .001 for noninferiority and .06 for superiority, but Dr. Li explained that these values may change when considering the site effect.
There were no statistically significant differences between the two drugs on secondary outcomes of favorable function. For example, 73% of tenecteplase patients and 72% of alteplase patients had an mRS score of 0-2 at 3 months, and 50% in the tenecteplase and 49% in the alteplase group improved by 4 or more points on the NIHSS, or had a score of 1 or less, at 24 hours.
The groups also had comparable scores on the European quality-of-life visual analogue scale and on the Barthel index, which measures functional independence related to personal care and mobility.
Tenecteplase also turned out to be as safe at alteplase. About 2% in both groups had symptomatic intracranial hemorrhage within 36 hours, and both groups had that same percentage for such hemorrhages within 90 days. As well, the groups had a similar rate of any intracranial hemorrhage within 90 days (6% and 7%).
The mortality rate was 7% in the tenecteplase group, compared with 5% in the alteplase group.
Adverse events (AEs) occurred in 86% and 87%, and serious AEs in 16% and 15%, of the tenecteplase and alteplase groups, respectively, again with no statistically significant differences.
The research team aims to test the effectiveness of tenecteplase in other stroke patients, including those with minor strokes, those receiving thrombolysis in a later window, and those receiving endovascular therapy, said Dr. Li.
Strong evidence
Commenting on the study findings, Larry B. Goldstein, MD, professor and chair of neurology, University of Kentucky, Lexington, said it is important to determine the efficacy of tenecteplase among Asians, as they represent “an entirely different population” with unique concerns, such as bleeding complications from anticoagulants.
He noted an advantage of tenecteplase is ease of administration. “You don’t have to go through the loading dose and then the 1-hour infusion,” which poses an “additional hassle” when transferring patients between institutions, he said.
However, he noted that a possible “downside” to having both drugs available in the emergency department is “using the wrong drug at the wrong dose” because of their similar sounding names.
Also commenting on the study, Tudor G. Jovin, MD, professor and chair, department of neurology, Rowan University, Camden, N.J., said he welcomes another trial that confirms that these two drugs are biologically similar.
“I’m very glad this trial was done because it adds another very strong piece of evidence of equivalency.”
But the two drugs are not the same in some important respects, said Dr. Jovin, whose center switched to using tenecteplase almost 3 years ago. That switch has resulted in cutting 17 minutes from the door-to-needle time “which is quite significant,” he said.
“There’s no question that once we used tenecteplase in lieu of tPA, it’s been just so much easier to administer and affects the interhospital transfer protocols, because you’re not transferring the patient with a critical care IV. It’s a win-win situation for everyone.”
The study received funding from the National Science and Technology Major Project, the Chinese Academy of Medical Sciences Innovation Fund for Medical Sciences, the National Natural Science Foundation of China, and the China Shijiazhuang Pharmaceutical Company Recomgen Pharmaceutical (Guangzhou). Dr. Li, Dr. Goldstein, and Dr. Jovin report no relevant financial relationships.

Adverse events (AEs) occurred in 86% and 87%, and serious AEs in 16% and 15%, of the tenecteplase and alteplase groups, respectively, again with no statistically significant differences.
The research team aims to test the effectiveness of tenecteplase in other stroke patients, including those with minor strokes, those receiving thrombolysis in a later window, and those receiving endovascular therapy, said Dr. Li.
Strong evidence
Commenting on the study findings, Larry B. Goldstein, MD, professor and chair of neurology, University of Kentucky, Lexington, said it is important to determine the efficacy of tenecteplase among Asians, as they represent “an entirely different population” with unique concerns, such as bleeding complications from anticoagulants.
He noted an advantage of tenecteplase is ease of administration. “You don’t have to go through the loading dose and then the 1-hour infusion,” which poses an “additional hassle” when transferring patients between institutions, he said.
However, he noted that a possible “downside” to having both drugs available in the emergency department is “using the wrong drug at the wrong dose” because of their similar sounding names.
Also commenting on the study, Tudor G. Jovin, MD, professor and chair, department of neurology, Rowan University, Camden, N.J., said he welcomes another trial that confirms that these two drugs are biologically similar.
“I’m very glad this trial was done because it adds another very strong piece of evidence of equivalency.”
But the two drugs are not the same in some important respects, said Dr. Jovin, whose center switched to using tenecteplase almost 3 years ago. That switch has resulted in cutting 17 minutes from the door-to-needle time “which is quite significant,” he said.
“There’s no question that once we used tenecteplase in lieu of tPA, it’s been just so much easier to administer and affects the interhospital transfer protocols, because you’re not transferring the patient with a critical care IV. It’s a win-win situation for everyone.”
The study received funding from the National Science and Technology Major Project, the Chinese Academy of Medical Sciences Innovation Fund for Medical Sciences, the National Natural Science Foundation of China, and the China Shijiazhuang Pharmaceutical Company Recomgen Pharmaceutical (Guangzhou). Dr. Li, Dr. Goldstein, and Dr. Jovin report no relevant financial relationships.
