MILAN – The therapeutic value of inhibiting the activity of IgE in patients with chronic spontaneous urticaria (CSU) was reinforced by two large phase 3 trials with ligelizumab, a drug characterized as a new generation anti-IgE monoclonal antibody.

Both doses of ligelizumab evaluated met the primary endpoint of superiority to placebo for a complete response at 16 weeks of therapy, reported Marcus Maurer, MD, director of the Urticaria Center for Reference and Excellence at the Charité Hospital, Berlin.

The data from the two identically designed trials, PEARL 1 and PEARL 2, were presented at the annual congress of the European Academy of Dermatology and Venereology. The two ligelizumab experimental arms (72 mg or 120 mg administered subcutaneously every 4 weeks) and the active comparative arm of omalizumab (300 mg administered subcutaneously every 4 weeks) demonstrated similar efficacy, all three of which were highly superior to placebo.

The data show that “another anti-IgE therapy – ligelizumab – is effective in CSU,” Dr. Maurer said.

“While the benefit was not different from omalizumab, ligelizumab showed remarkable results in disease activity and by demonstrating just how many patients achieved what we want them to achieve, which is to have no more signs and symptoms,” he added.
 

Majority of participants with severe urticaria

All of the patients entered into the two trials had severe (about 65%) or moderate (about 35%) symptoms at baseline. The results of the two trials were almost identical. In the randomization arms, a weekly Urticaria Activity Score (UAS7) of 0, which was the primary endpoint, was achieved at week 16 by 31.0% of those receiving 72-mg ligelizumab, 38.3% of those receiving 120-mg ligelizumab, and 34.1% of those receiving omalizumab (Xolair). The placebo response was 5.7%.

The UAS7 score is drawn from two components, wheals and itch. The range is 0 (no symptoms) to 42 (most severe). At baseline, the average patients’ scores were about 30, which correlates with a substantial symptom burden, according to Dr. Maurer.

The mean reduction in the UAS7 score in PEARL 2, which differed from PEARL 1 by no more than 0.4 points for any treatment group, was 19.2 points in the 72-mg ligelizumab group, 19.3 points in the 120-mg ligelizumab group, 19.6 points in the omalizumab group, and 9.2 points in the placebo group. There were no significant differences between any active treatment arm.

Complete symptom relief, meaning a UAS7 score of 0, was selected as the primary endpoint, because Dr. Maurer said that this is the goal of treatment. Although he admitted that a UAS7 score of 0 is analogous to a PASI score in psoriasis of 100 (complete clearing), he said, “Chronic urticaria is a debilitating disease, and we want to eliminate the symptoms. Gone is gone.”

Combined, the two phase 3 trials represent “the biggest chronic urticaria program ever,” according to Dr. Maurer. The 1,034 patients enrolled in PEARL 1 and the 1,023 enrolled in PEARL 2 were randomized in a 3:3:3:1 ratio with placebo representing the smaller group.

The planned follow-up is 52 weeks, but the placebo group will be switched to 120 mg ligelizumab every 4 weeks at the end of 24 weeks. The switch is required because “you cannot maintain patients with this disease on placebo over a long period,” Dr. Maurer said.
 

Ligelizumab associated with low discontinuation rate

Adverse events overall and stratified by severity have been similar across treatment arms, including placebo. The possible exception was a lower rate of moderate events (16.5%) in the placebo arm relative to the 72-mg ligelizumab arm (19.8%), the 120-mg ligelizumab arm (21.6%), and the omalizumab arm (22.3%). Discontinuations because of an adverse event were under 4% in every treatment arm.

Although Dr. Maurer did not present outcomes at 52 weeks, he did note that “only 15% of those who enrolled in these trials have discontinued treatment.” He considered this remarkable in that the study was conducted in the midst of the COVID-19 pandemic, and it appears that at least some of those left the trial did so because of concern for clinic visits.

Despite the similar benefit provided by ligelizumab and omalizumab, Dr. Maurer said that subgroup analyses will be coming. The possibility that some patients benefit more from one than the another cannot yet be ruled out. There are also, as of yet, no data to determine whether at least some patients respond to one after an inadequate response to the other.

Still, given the efficacy and the safety of ligelizumab, Dr. Maurer indicated that the drug is likely to find a role in routine management of CSU if approved.

“We only have two options for chronic spontaneous urticaria. There are antihistamines, which do not usually work, and omalizumab,” he said. “It is very important we develop more treatment options.”

Adam Friedman, MD, professor and chair of dermatology, George Washington University, Washington, agreed.

“More therapeutic options, especially for disease states that have a small armament – even if equivalent in efficacy to established therapies – is always a win for patients as it almost always increases access to treatment,” Dr. Friedman said in an interview.

“Furthermore, the heterogeneous nature of inflammatory skin diseases is often not captured in even phase 3 studies. Therefore, having additional options could offer relief where previous therapies have failed,” he added.

Dr. Maurer reports financial relationships with more than 10 pharmaceutical companies, including Novartis, which is developing ligelizumab. Dr. Friedman has a financial relationship with more than 20 pharmaceutical companies but has no current financial association with Novartis and was not involved in the PEARL 1 and 2 trials.

Chronic pruritus occurs in 1 out of 3 patients with multiple sclerosis (MS) and may be associated with more advanced disease, according to investigators.

Itch is historically underrecognized as a symptom of MS, but physicians should know that it is common and may negatively impact quality of life, reported lead author Giuseppe Ingrasci, MD, a dermatology research fellow at the University of Miami, Miller School of Medicine, and colleagues.

A common problem that may indicate more severe disease

At the Multiple Sclerosis Center of Excellence in Miami, 27 out of 79 outpatients with MS (35%) reported pruritus, with an average severity of 5.42 out of 10. Among those with itch, the extremities were affected in about half of the patients, while the face, scalp, and trunk were affected in about one-third of the patients. Many described paroxysmal itch that was aggravated by heat, and about half experienced itch on a weekly basis.

Further investigation showed that itch was associated with more severe MS. Compared with patients not experiencing itch, those with itch were significantly more likely to report fatigue (77% vs. 44%), anxiety or depression (48% vs. 16%), and cognitive impairment (62% vs. 26%).

MRI findings backed up these clinical results. Compared with patients not experiencing itch, patients with itch had significantly more T2 hyperintensities in the posterior cervical cord (74.1% vs. 46.0%) and anterior pons/ventromedial medulla (62% vs. 26%). These hyperintensities in the medulla were also associated with an 11-fold increased rate of itch on the face or scalp (odds ratio, 11.3; 95% confidence interval, 1.6-78.6, P = 0.025).

“Health care providers should be aware of episodes of localized, neuropathic itch in MS patients, as they appear to be more prevalent than previously thought and may impair these patients’ quality of life,” the investigators concluded.
 

Challenges with symptom characterization, management

“This is an important study for both patients and clinicians,” said Justin Abbatemarco, MD, of Cleveland Clinic’s Mellen Center for Multiple Sclerosis, in a written comment. “As the authors mention, many of our patients experience transient symptoms, including many different types of sensory disturbance (that is, pins & needles, burning, electrical shocks, and itching). These symptoms can be really distressing for patients and their caregivers.”

While Dr. Abbatemarco has encountered severe itching in “several patients” with MS, he maintained that it is “relatively uncommon” and noted that MS symptomatology is an inherently cloudy subject.

Cool the itch?

Noting how heat appears to aggravate itch in patients with MS, Dr. Yosipovitch suggested that one of those unique – and simple – treatment approaches may be cooling itchy areas. Alternatively, clinicians may consider oral agents, like gabapentin to dampen neural transmission, or compounded formulations applied to the skin to reduce neural sensitivity, such as topical ketamine. Finally, Dr. Yosipovitch speculated that newer antibody agents for MS could potentially reduce itch.

All these treatment suggestions are purely hypothetical, he said, and require further investigation before they can be recommended with confidence.

The investigators disclosed relationships with Galderma, Pfizer, Novartis, and others. Dr. Abbatemarco disclosed no conflicts of interest.

U.S. veterans of the post-9/11 wars who suffered a traumatic brain injury (TBI) are at increased risk of developing cardiovascular disease (CVD). More severe TBI is associated with higher risk of CVD, new research shows.

Given the relatively young age of post-9/11–era veterans with TBI, there may be an increased burden of heart disease in the future as these veterans age and develop traditional risk factors for CVD, the investigators, led by Ian J. Stewart, MD, with Uniformed Services University, Bethesda, Md., wrote.

The study was published online  in JAMA Neurology.
 

Novel data

Since Sept. 11, 2001, 4.5 million people have served in the U.S. military, with their time in service defined by the long-running wars in Iraq and Afghanistan. Estimates suggest that up to 20% of post-9/11 veterans sustained a TBI.

While some evidence suggests that TBI increases the risk of CVD, prior reports have focused mainly on cerebrovascular outcomes. Until now, the potential association of TBI with CVD has not been comprehensively examined in post-9/11–era veterans.

The retrospective cohort study included 1,559,928 predominantly male post-9/11 veterans, including 301,169 (19.3%) with a history of TBI and 1,258,759 (81%) with no TBI history.

In fully adjusted models, compared with veterans with no TBI history, a history of mild, moderate/severe, or penetrating TBI was associated with increased risk of developing the composite CVD endpoint (coronary artery disease, stroke, peripheral artery disease, and CVD death).

Unrecognized CVD risk factor?

Reached for comment, Shaheen E. Lakhan, MD, PhD, a neurologist and researcher from Boston who wasn’t involved in the study, said the effects of TBI on heart health are “very underreported, and most clinicians would not make the link.”

“When the brain suffers a traumatic injury, it activates a cascade of neuro-inflammation that goes haywire in an attempt to protect further brain damage. Oftentimes, these inflammatory by-products leak into the body, especially in trauma, when the barriers are broken between brain and body, and can cause systemic body inflammation, which is well associated with heart disease,” Dr. Lakhan said.

In addition, Dr. Lakhan said, “TBI itself localized to just the brain can negatively affect good health habits, leading to worsening heart health, too.”

“Research like this brings light where not much exists and underscores the importance of protecting our brains from physical trauma,” he said.

The study was supported by the assistant secretary of defense for health affairs, endorsed by the Department of Defense through the Psychological Health/Traumatic Brain Injury Research Program Long-Term Impact of Military-Relevant Brain Injury Consortium, and by the U.S. Department of Veterans Affairs. Dr. Stewart and Dr. Lakhan have disclosed no relevant financial relationships.

While some evidence suggests that TBI increases the risk of CVD, prior reports have focused mainly on cerebrovascular outcomes. Until now, the potential association of TBI with CVD has not been comprehensively examined in post-9/11–era veterans.

The retrospective cohort study included 1,559,928 predominantly male post-9/11 veterans, including 301,169 (19.3%) with a history of TBI and 1,258,759 (81%) with no TBI history.

In fully adjusted models, compared with veterans with no TBI history, a history of mild, moderate/severe, or penetrating TBI was associated with increased risk of developing the composite CVD endpoint (coronary artery disease, stroke, peripheral artery disease, and CVD death).

Unrecognized CVD risk factor?

Reached for comment, Shaheen E. Lakhan, MD, PhD, a neurologist and researcher from Boston who wasn’t involved in the study, said the effects of TBI on heart health are “very underreported, and most clinicians would not make the link.”

“When the brain suffers a traumatic injury, it activates a cascade of neuro-inflammation that goes haywire in an attempt to protect further brain damage. Oftentimes, these inflammatory by-products leak into the body, especially in trauma, when the barriers are broken between brain and body, and can cause systemic body inflammation, which is well associated with heart disease,” Dr. Lakhan said.

In addition, Dr. Lakhan said, “TBI itself localized to just the brain can negatively affect good health habits, leading to worsening heart health, too.”

“Research like this brings light where not much exists and underscores the importance of protecting our brains from physical trauma,” he said.

The study was supported by the assistant secretary of defense for health affairs, endorsed by the Department of Defense through the Psychological Health/Traumatic Brain Injury Research Program Long-Term Impact of Military-Relevant Brain Injury Consortium, and by the U.S. Department of Veterans Affairs. Dr. Stewart and Dr. Lakhan have disclosed no relevant financial relationships.

Ketamine may be an effective treatment for children with activity-dependent neuroprotective protein (ADNP) syndrome, a rare genetic condition associated with intellectual disability and autism spectrum disorder.

Also known as Helsmoortel–Van Der Aa syndrome, ADNP syndrome is caused by mutations in the ADNP gene. Studies in animal models suggest that low-dose ketamine increases expression of ADNP and is neuroprotective.

Intrigued by the preclinical evidence, Alexander Kolevzon, MD, clinical director of the Seaver Autism Center at Mount Sinai, New York, and colleagues treated 10 children with ADNP syndrome with a single low dose of ketamine (0.5mg/kg) infused intravenously over 40 minutes. The children ranged in ages 6-12 years.

Using parent-report instruments to assess treatment effects, ketamine was associated with “nominally significant” improvement in a variety of domains, including social behavior, attention-deficit and hyperactivity, restricted and repetitive behaviors, and sensory sensitivities.

Parent reports of improvement in these domains aligned with clinician-rated assessments based on the Clinical Global Impressions–Improvement scale.

The results also highlight the potential utility of electrophysiological measurement of auditory steady-state response and eye-tracking to track change with ketamine treatment, the researchers say.

The study was published online in Human Genetics and Genomic (HGG) Advances.
 

Hypothesis-generating

Ketamine was generally well tolerated. There were no clinically significant abnormalities in laboratory or cardiac monitoring, and there were no serious adverse events (AEs).

Treatment emergent AEs were all mild to moderate and no child required any interventions.

The most common AEs were elation/silliness in five children (50%), all of whom had a history of similar symptoms. Drowsiness and fatigue occurred in four children (40%) and two of them had a history of drowsiness. Aggression was likewise relatively common, reported in four children (40%), all of whom had aggression at baseline.

Decreased appetite emerged as a new AE in three children (30%), increased anxiety occurred in three children (30%), and irritability, nausea/vomiting, and restlessness each occurred in two children (20%).

The researchers caution that the findings are intended to be “hypothesis generating.”

“We are encouraged by these findings, which provide preliminary support for ketamine to help reduce negative effects of this devastating syndrome,” Dr. Kolevzon said in a news release from Mount Sinai.

Ketamine might help ease symptoms of ADNP syndrome “by increasing expression of the ADNP gene or by promoting synaptic plasticity through glutamatergic pathways,” Dr. Kolevzon told this news organization.

The next step, he said, is to get “a larger, placebo-controlled study approved for funding using repeated dosing over a longer duration of time. We are working with the FDA to get the design approved for an investigational new drug application.”

Support for the study was provided by the ADNP Kids Foundation and the Foundation for Mood Disorders. Support for mediKanren was provided by the National Center for Advancing Translational Sciences, and National Institutes of Health through the Biomedical Data Translator Program. Dr. Kolevzon is on the scientific advisory board of Ovid Therapeutics, Ritrova Therapeutics, and Jaguar Therapeutics and consults to Acadia, Alkermes, GW Pharmaceuticals, Neuren Pharmaceuticals, Clinilabs Drug Development Corporation, and Scioto Biosciences.

A long time ago, as a fourth-year medical student, I did a neurology rotation at a large academic center.

One of the attendings was talking to me about reading, and how, once learned, it became innate: a function that, like breathing, couldn’t be turned off.

He was right, as is obvious to anyone. Driving down the road, walking past a newsstand, even opening a fridge covered with magnets from various other medical businesses ... it’s impossible NOT to process the letters into words and words into meanings, even if just for a second. Advertisers and headline-writers figured this out long ago. The key is to make those few words something that grabs our attention and interest, so we’ll either want to read more or retain it.

So too is being a doctor. Once that switch is on, you can’t flip it off. We all come to this field with varying degrees of curiosity and analytical ability, and once those are refined by experience they don’t shut down.

Recently Queen Elizabeth II died. In reading the news stories, without intending to, I found my mind trying to pick out details about her medical condition, formulate a differential ... after all these years of being in medicine it’s second nature to do that.

Of course, it’s none of my business, and I greatly respect personal privacy. But the point is there. At some point, like reading, we can’t turn off the doctor circuit (for lack of a better term). We do it all the time, analyzing gait patterns and arm swings as people go by. Noticing facial asymmetries, tremors, speech patterns. It may be turned down a few notches from when we’re in the office or hospital, but it’s still there.

It becomes second nature, a part of who we are.

It’s not just doctors. Architects casually notice building details that no one else would. Software engineers off-handedly see program features (good and bad) that the rest of us wouldn’t. Teachers and editors pick up on grammatical errors even when they’re not trying to.

None of these (aside from basic observation) are things that brains originally started out to do. But through training and experience we’ve adapted them to do this. We never stop observing, collecting data, and processing it, in ways peculiar to our backgrounds.

Which, if you think about it, is pretty remarkable.

A recent uptick in severe respiratory illness in children may be tied to a strain of enterovirus that can cause a rare polio-like condition, according to a Health Network Alert advisory by the Centers for Disease Control and Prevention.

In August, health care providers and hospitals notified the CDC of an increase in severe respiratory illness in children who also tested positive for rhinovirus (RV) or enterovirus (EV). Additional testing revealed that some children were positive for EV-D68, which primarily causes acute respiratory illness. However, the virus has been associated with acute flaccid myelitis (AFM), a rare neurologic condition involving muscle weakness.

Also, in July and August 2022, surveillance networks reported an increase in EV-D68 activity compared with the same months in 2019, 2020, and 2021, the agency said in the alert. As of Aug. 30, the CDC has not received any reports of AFM beginning this year; however, spikes in EV-D68 typically come before cases of AFM, they said.

“Something we are always on the lookout for in the late summer and fall is AFM cases,” said Rick Malley, MD, of the division of infectious disease at Boston Children’s Hospital, in an interview with this news organization. “Unfortunately, we kind of expect them during enterovirus season,” he said. That season is thought to peak in the late summer and early fall.

Since the CDC began tracking AFM in August 2014, there have been 692 confirmed cases in the United States. AFM cases spiked in 2014, 2016, and 2018, mostly in young children. In 2021, there were 28 confirmed cases across 15 states. The CDC did not specify the age of those cases, but in 2018 – when EV-D68 most recently circulated at high levels – the median age of children who visited the emergency department or were hospitalized for EV-D68–associated respiratory illness was 3 years.

“[AFM] can be very severe and it can be very scary for the parents of children who have it,” Dr. Malley said, “but given the prevalence of enteroviruses in the community, you have to conclude it’s a relatively rare event in susceptible individuals. Why some get it and others don’t is unfortunately unclear at this moment.”

The CDC recommends that providers consider EV-D68 as a possible cause for acute, severe respiratory illness in children. If the cause of a respiratory illness in a severely ill patient is not clear, health professionals should test for RVs and EVs, if this is not already part of a typical diagnostic workflow, the agency said. Currently, there are no vaccines or specific treatments for RV or EV, and the CDC recommends supportive clinical management.

The advisory also urged providers to “strongly consider AFM in patients with acute flaccid limb weakness, especially after respiratory illness or fever, and between the months of August and November 2022.”

For any patient presenting with possible AFM, clinicians should collect samples from multiple sources, including cerebrospinal fluid, serum, stool, and a nasopharyngeal or oropharyngeal swab. Samples should be taken “as early as possible and preferably on the day of onset of limb weakness,” the alert said. There is currently no specific medicine for AFM, the agency said, though recommended interventions may vary for each patient.

A new study provides yet more evidence that a significant subset of people who experience persistent fatigue and exercise intolerance following COVID-19 will meet diagnostic criteria for myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS).

Data from the prospective observational study of 42 patients with “post-COVID-19 syndrome (PCS),” including persistent fatigue and exercise intolerance, suggest that a large proportion will meet strict diagnostic criteria for ME/CFS, including the hallmark postexertional malaise (PEM). Still others may experience similar disability but lack duration and/or severity requirements for the diagnosis.

Moreover, disease severity and symptom burden were found similar in those with ME/CFS following COVID-19 and in a group of 19 age- and sex-matched individuals with ME/CFS that wasn’t associated with COVID-19.

“The major finding is that ME/CFS is indeed part of the spectrum of the post-COVID syndrome and very similar to the ME/CFS we know after other infectious triggers,” senior author Carmen Scheibenbogen, MD, acting director of the Institute for Medical Immunology at the Charité University Medicine Campus Virchow-Klinikum, Berlin, told this news organization.

Importantly, from a clinical standpoint, both diminished hand-grip strength (HGS) and orthostatic intolerance were common across all patient groups, as were several laboratory values, Claudia Kedor, MD, and colleagues at Charité report in the paper, published online in Nature Communications.

Of the 42 with PCS, including persistent fatigue and exercise intolerance lasting at least 6 months, 19 met the rigorous Canadian Consensus Criteria (CCC) for ME/CFS, established in 2003, which require PEM, along with sleep dysfunction, significant persistent fatigue, pain, and several other symptoms from neurological/cognitive, autonomic, neuroendocrine, and immune categories that persist for at least 6 months.

Of the 23 who did not meet the CCC criteria, 18 still experienced PEM but for less than the required 14 hours set by the authors based on recent data. The original CCC had suggested 24 hours as the PEM duration. Eight subjects met all the Canadian criteria except for the neurological/cognitive symptoms. None of the 42 had evidence of severe depression.

The previously widely used 1994 “Fukuda” criteria for ME/CFS are no longer recommended because they don’t require PEM, which is now considered a key symptom. The more recent 2015 Institute (now Academy) of Medicine criteria don’t define the length of PEM, the authors note in the paper.

Dr. Scheibenbogen said, “Post-COVID has a spectrum of syndromes and conditions. We see that a subset of patients have similar symptoms of ME/CFS but don’t fulfill the CCC, although they may meet less stringent criteria. We think this is of relevance for both diagnostic markers and development of therapy, because there may be different pathomechanisms between the subsets of post-COVID patients.”

She pointed to other studies from her group suggesting that inflammation is present early in post-COVID (not yet published), while in the subset that goes on to ME/CFS, autoantibodies or endothelial dysfunction play a more important role. «At the moment, it’s quite complex, and I don’t think in the end we will have just one pathomechanism. So I think we’ll need to develop various treatment strategies.”

Asked to comment on the new data, Anthony L. Komaroff, MD, professor of medicine at Harvard Medical School, senior physician at Brigham and Women’s Hospital, both in Boston, and editor in chief of the Harvard Health Letter, told this news organization, “This paper adds to the evidence that an illness with symptoms that meet criteria for ME/CFS can follow COVID-19 in nearly half of those patients who have lingering symptoms. This can occur even in people who initially have only mild symptoms from COVID-19, although it is more likely to happen in the people who are sickest when they first get COVID-19. And those who meet criteria for ME/CFS were seriously impaired in their ability to function, [both] at work and at home.”

But, Dr. Komaroff also cautioned, “the study does not help in determining what fraction of all people who are infected with SARS-CoV-2 go on to develop a condition like ME/CFS, nor how long that condition will last. It is crucial that we get answers to these questions, as the impact on the economy, the health care system, and the disability system could be substantial.”

He pointed to a recent report from the Brookings Institution (2022 Aug 24. “New data shows long Covid is keeping as many as 4 million people out of work” Katie Bach) “finding that “long COVID may be a major contributor to the shortage of job applicants plaguing many businesses.”
 

Biomarkers include hand-grip strength, orthostatic intolerance, lab measures

Hand-grip strength, as assessed by 10 repeat grips at maximum force and repeated after 60 minutes, were lower for all those meeting ME/CFS criteria, compared with the healthy controls. Hand-grip strength parameters were also positively correlated with laboratory hemoglobin measures in both PCS groups who did and didn’t meet the Canadian ME/CFS criteria.

A total of three patients with PCS who didn’t meet ME/CFS criteria and seven with PCS who met ME/CFS criteria had sitting blood pressures of greater than 140 mm Hg systolic and/or greater than 90 mm Hg diastolic. Five patients with PCS – four who met ME/CFS criteria and one who didn’t – fulfilled criteria for postural orthostatic tachycardia syndrome. Orthostatic hypotension was diagnosed in a total of seven with PCS, including one who did not meet ME/CFS criteria and the rest who did.

Among significant laboratory findings, mannose-binding lectin deficiency, which is associated with increased infection susceptibility and found in only about 6% of historical controls, was found more frequently in both of the PCS cohorts (17% of those with ME/CFS and 23% of those without) than it has been in the past among those with ME/CFS, compared with historical controls (15%).

There was only slight elevation in C-reactive protein, the most commonly measured marker of inflammation. However, another marker indicating inflammation within the last 3-4 months, interleukin 8 assessed in erythrocytes, was above normal in 37% with PCS and ME/CFS and in 48% with PCS who did not meet the ME/CFS criteria.

Elevated antinuclear antibodies, anti–thyroid peroxidase antibodies, vitamin D deficiencies, and folic acid deficiencies were all seen in small numbers of the PCS patients. Angiotensin-converting enzyme 1 levels were below the normal range in 31% of all patients.

“We must anticipate that this pandemic has the potential to dramatically increase the number of ME/CFS patients,” Dr. Kedor and colleagues write. “At the same time, it offers the unique chance to identify ME/CFS patients in a very early stage of disease and apply interventions such as pacing and coping early with a better therapeutic prognosis. Further, it is an unprecedented opportunity to understand the underlying pathomechanism and characterize targets for specific treatment approaches.”

A new study provides yet more evidence that a significant subset of people who experience persistent fatigue and exercise intolerance following COVID-19 will meet diagnostic criteria for myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS).

Data from the prospective observational study of 42 patients with “post-COVID-19 syndrome (PCS),” including persistent fatigue and exercise intolerance, suggest that a large proportion will meet strict diagnostic criteria for ME/CFS, including the hallmark postexertional malaise (PEM). Still others may experience similar disability but lack duration and/or severity requirements for the diagnosis.

Moreover, disease severity and symptom burden were found similar in those with ME/CFS following COVID-19 and in a group of 19 age- and sex-matched individuals with ME/CFS that wasn’t associated with COVID-19.

“The major finding is that ME/CFS is indeed part of the spectrum of the post-COVID syndrome and very similar to the ME/CFS we know after other infectious triggers,” senior author Carmen Scheibenbogen, MD, acting director of the Institute for Medical Immunology at the Charité University Medicine Campus Virchow-Klinikum, Berlin, told this news organization.

Importantly, from a clinical standpoint, both diminished hand-grip strength (HGS) and orthostatic intolerance were common across all patient groups, as were several laboratory values, Claudia Kedor, MD, and colleagues at Charité report in the paper, published online in Nature Communications.

Of the 42 with PCS, including persistent fatigue and exercise intolerance lasting at least 6 months, 19 met the rigorous Canadian Consensus Criteria (CCC) for ME/CFS, established in 2003, which require PEM, along with sleep dysfunction, significant persistent fatigue, pain, and several other symptoms from neurological/cognitive, autonomic, neuroendocrine, and immune categories that persist for at least 6 months.

Of the 23 who did not meet the CCC criteria, 18 still experienced PEM but for less than the required 14 hours set by the authors based on recent data. The original CCC had suggested 24 hours as the PEM duration. Eight subjects met all the Canadian criteria except for the neurological/cognitive symptoms. None of the 42 had evidence of severe depression.

The previously widely used 1994 “Fukuda” criteria for ME/CFS are no longer recommended because they don’t require PEM, which is now considered a key symptom. The more recent 2015 Institute (now Academy) of Medicine criteria don’t define the length of PEM, the authors note in the paper.

Dr. Scheibenbogen said, “Post-COVID has a spectrum of syndromes and conditions. We see that a subset of patients have similar symptoms of ME/CFS but don’t fulfill the CCC, although they may meet less stringent criteria. We think this is of relevance for both diagnostic markers and development of therapy, because there may be different pathomechanisms between the subsets of post-COVID patients.”

She pointed to other studies from her group suggesting that inflammation is present early in post-COVID (not yet published), while in the subset that goes on to ME/CFS, autoantibodies or endothelial dysfunction play a more important role. «At the moment, it’s quite complex, and I don’t think in the end we will have just one pathomechanism. So I think we’ll need to develop various treatment strategies.”

Asked to comment on the new data, Anthony L. Komaroff, MD, professor of medicine at Harvard Medical School, senior physician at Brigham and Women’s Hospital, both in Boston, and editor in chief of the Harvard Health Letter, told this news organization, “This paper adds to the evidence that an illness with symptoms that meet criteria for ME/CFS can follow COVID-19 in nearly half of those patients who have lingering symptoms. This can occur even in people who initially have only mild symptoms from COVID-19, although it is more likely to happen in the people who are sickest when they first get COVID-19. And those who meet criteria for ME/CFS were seriously impaired in their ability to function, [both] at work and at home.”

But, Dr. Komaroff also cautioned, “the study does not help in determining what fraction of all people who are infected with SARS-CoV-2 go on to develop a condition like ME/CFS, nor how long that condition will last. It is crucial that we get answers to these questions, as the impact on the economy, the health care system, and the disability system could be substantial.”

He pointed to a recent report from the Brookings Institution (2022 Aug 24. “New data shows long Covid is keeping as many as 4 million people out of work” Katie Bach) “finding that “long COVID may be a major contributor to the shortage of job applicants plaguing many businesses.”
 

Biomarkers include hand-grip strength, orthostatic intolerance, lab measures

Hand-grip strength, as assessed by 10 repeat grips at maximum force and repeated after 60 minutes, were lower for all those meeting ME/CFS criteria, compared with the healthy controls. Hand-grip strength parameters were also positively correlated with laboratory hemoglobin measures in both PCS groups who did and didn’t meet the Canadian ME/CFS criteria.

A total of three patients with PCS who didn’t meet ME/CFS criteria and seven with PCS who met ME/CFS criteria had sitting blood pressures of greater than 140 mm Hg systolic and/or greater than 90 mm Hg diastolic. Five patients with PCS – four who met ME/CFS criteria and one who didn’t – fulfilled criteria for postural orthostatic tachycardia syndrome. Orthostatic hypotension was diagnosed in a total of seven with PCS, including one who did not meet ME/CFS criteria and the rest who did.

Among significant laboratory findings, mannose-binding lectin deficiency, which is associated with increased infection susceptibility and found in only about 6% of historical controls, was found more frequently in both of the PCS cohorts (17% of those with ME/CFS and 23% of those without) than it has been in the past among those with ME/CFS, compared with historical controls (15%).

During a medical malpractice trial in New Jersey, jurors waited nearly 4 hours for the physician defendant to show up. When he did arrive, the body-building surgeon was sporting two thick gold chains and a diamond pinky ring, and had the top buttons of his shirt open enough to reveal his chest hair.

“This trial was in a very rural, farming community,” recalls medical liability defense attorney Catherine Flynn, of Flynn Watts LLC, based in Parsippany, N.J. “Many of the jurors were wearing flannel shirts and jeans. The doctor’s wife walked in wearing a five-carat diamond ring and other jewelry.”

Ms. Flynn took the couple aside and asked them to remove the jewelry. She explained that the opulent accessories could damage the jury’s view of the physician. The surgeon and his wife, however, refused to remove their jewelry, she said. They didn’t think it was a big deal.

The case against the surgeon involved intraoperative damage to a patient when the physician inadvertently removed a portion of nerve in the area of the procedure. After repair of the nerve, the patient had a positive result. However, the patient alleged the surgeon’s negligence resulted in permanent damage despite the successful repair.

Jurors ultimately found the physician negligent in the case and awarded the plaintiff $1.2 million. Ms. Flynn believes that physician’s flamboyant attire and arrogant nature tainted the jury’s decision.

“In certain counties in New Jersey, his attire would not have been a problem,” she said. “In this rural, farming county, it was a huge problem. You have to know your audience. There are a lot of other things that come into play in a medical malpractice case, but when it comes to damages in a case, you don’t want to be sending the message that supports what somebody’s bias may already be telling them about a doctor.”

The surgeon appealed the verdict, and the case ultimately settled for a lesser amount, according to Ms. Flynn.

An over-the-top wardrobe is just one way that physicians can negatively influence jurors during legal trials. From subtle facial expressions to sudden outbursts to downright rudeness, attorneys have witnessed countless examples of physicians sabotaging their own trials. Legal experts say the cringeworthy experiences are good reminders that jurors are often judging more than just evidence.  

“The minute you enter the courthouse, jurors or potential jurors are sizing you up,” says health law attorney Michael Clark, of Womble Bond Dickinson (US) LLP, based in Houston. “The same phenomenon occurs in a deposition. Awareness of how you are being assessed at all times, and the image that is needed, is important since a negative impression by jurors can have a detrimental effect on a physician’s case.”
 

Juror: We didn’t like the doctor’s shoes

In another case, attorneys warned a physician defendant against dressing in his signature wardrobe during his trial. Against their advice, the doctor showed up daily to his trial in bright pastel, monochromatic suits with matching Gucci-brand shoes, said medical liability defense attorney Meredith C. Lander, of Kaufman Borgeest & Ryan LLP, based in Connecticut. On the witness stand, the doctor was long-winded and wasn’t “terribly likable,” Ms. Lander said.

However, the evidence weighed in the physician’s favor, and there was strong testimony by defense experts. The physician won the case, Ms. Lander said, but after the verdict, the jury foreperson approached the trial attorney and made some disparaging remarks about the defendant.

“The foreperson said the jury didn’t like the doctor or his ‘Gucci suits and shoes,’ but they believed the experts,” Ms. Lander said.

Disruptive behavior can also harm jurors’ perception of physicians, Ms. Flynn adds. During one instance, a surgeon insisted on sitting next to Ms. Flynn, although she generally requests clients sit in the first row so that jurors are not so focused on their reactions during testimony. The surgeon loudly peppered Ms. Flynn with questions as witnesses testified, prompting a reprimand from the judge.

“The judge admonished the doctor several times and said, ‘Doctor, you’re raising your voice. You’ll get a chance to speak with your attorney during the break,’ ” Ms. Flynn recalled. “The doctor refused to stop talking, and the judge told him in front of the jury to go sit in the back of the courtroom. His reaction was, ‘Why do I have to move?! I need to sit here!’ ”

The surgeon eventually moved to the back of the courtroom and a sheriff’s deputy stood next to him. Testimony continued until a note in the form of a paper airplane landed on the table in front of Ms. Flynn. She carefully crumpled the note and tossed it in the wastebasket. Luckily, this drew a laugh from jurors, she said. 

But things got worse when the surgeon testified. Rather than answer the questions, he interrupted and started telling jurors his own version of events.

“The judge finally said, ‘Doctor, if you don’t listen to your attorney and answer her questions, I’m going to make you get off the stand,’ ” Ms. Flynn said. “That was the most unbelievable, egregious self-sabotage trial moment I’ve ever experienced.”

Fortunately, the physician’s legal case was strong, and the experts who testified drove the defense’s side home, Ms. Flynn said. The surgeon won the case.
 

Attorney: Watch what you say in the elevator

Other, more subtle behaviors – while often unintentional – can also be damaging.

Physicians often let their guard down while outside the courtroom and can unknowingly wind up next to a juror in an elevator or standing in a hallway, said Laura Postilion, a partner at Quintairos, Prieto, Wood & Boyer, P.A., based in Chicago.

“For instance, a doctor is in an elevator and feels that some witness on the stand was lying,” Ms. Postilion said. “They might be very upset about it and start ranting about a witness lying, not realizing there is a juror is in the elevator with you.”

Physicians should also be cautious when speaking on the phone to their family or friends during a trial break.

“At the Daley Center in downtown Chicago, there are these long corridors and long line of windows; a lot of people will stand there during breaks. A doctor may be talking to his or her spouse and saying, ‘Yeah, this juror is sleeping!’ Jurors are [often] looking for drama. They’re looking for somebody letting their guard down. Hearing a doctor speak badly about them would certainly give them a reason to dislike the physician.”

Ms. Postilion warns against talking about jurors in or outside of the courtroom. This includes parking structures, she said.

Physicians can take additional steps to save themselves from negative judgment from jurors, attorneys say. Even before the trial starts, Ms. Postilion advises clients to make their social media accounts private. Some curious jurors may look up a physician’s social media accounts to learn more about their personal life, political leanings, or social beliefs, which could prejudice them against the doctor, she said.

Once on the stand, the words and tone used are key. The last thing a physician defendant wants is to come across as arrogant or condescending to jurors, said medical liability defense attorney Michael Moroney, of Flynn Watts LLC.

“For instance, a defendant might say, ‘Well, let me make this simple for you,’ as if they’re talking to a bunch of schoolchildren,” he said. “You don’t know who’s on the jury. That type of language can be offensive.”

Ms. Lander counsels her clients to refrain from using the common phrase, “honestly,” before answering questions on the stand.

“Everything you’re saying on the stand is presumed to be honest,” she said. “When you start an answer with, ‘Honestly…’ out of habit, it really does undercut everything that follows and everything else that’s already been said. It suggests that you were not being honest in your other answers.”
 

Attitude, body language speak volumes

Keep in mind that plaintiffs’ attorneys will try their best to rattle physicians on the stand and get them to appear unlikeable, says Mr. Clark, the Houston-based health law attorney. Physicians who lose their cool and begin arguing with attorneys play into their strategy.

“Plaintiffs’ attorneys have been trained in ways to get under their skin,” he said. “Righteous indignation and annoyance are best left for a rare occasion. Think about how you feel in a social setting when people are bickering in front of you. It’s uncomfortable at best. That’s how a jury feels too.”

Body language is also important, Mr. Clark notes. Physicians should avoid crossed arms, leaning back and rocking, or putting a hand on their mouth while testifying, he said. Many attorneys have practice sessions with their clients and record the interaction so that doctors can watch it and see how they look.

“Know your strengths and weaknesses,” he said. “Get help from your lawyer and perhaps consultants about how to improve these skills. Practice and preparation are important.”

Ms. Postilion goes over courtroom clothing with physician clients before trial. Anything “too flashy, too high-end, or too dumpy” should be avoided, she said. Getting accustomed to the courtroom and practicing in an empty courtroom are good ways to ensure that a physician’s voice is loud enough and projecting far enough in the courtroom, she adds.

“The doctor should try to be the best version of him- or herself to jurors,” she said. “A jury can pick up someone who’s trying to be something they’re not. A good attorney can help the doctor find the best version of themselves and capitalize on it. What is it that you want the jury to know about your care of the patient? Take that overall feeling and make sure it’s clearly expressed to the jury.”

Ms. Flynn took the couple aside and asked them to remove the jewelry. She explained that the opulent accessories could damage the jury’s view of the physician. The surgeon and his wife, however, refused to remove their jewelry, she said. They didn’t think it was a big deal.

The case against the surgeon involved intraoperative damage to a patient when the physician inadvertently removed a portion of nerve in the area of the procedure. After repair of the nerve, the patient had a positive result. However, the patient alleged the surgeon’s negligence resulted in permanent damage despite the successful repair.

Jurors ultimately found the physician negligent in the case and awarded the plaintiff $1.2 million. Ms. Flynn believes that physician’s flamboyant attire and arrogant nature tainted the jury’s decision.

“In certain counties in New Jersey, his attire would not have been a problem,” she said. “In this rural, farming county, it was a huge problem. You have to know your audience. There are a lot of other things that come into play in a medical malpractice case, but when it comes to damages in a case, you don’t want to be sending the message that supports what somebody’s bias may already be telling them about a doctor.”

The surgeon appealed the verdict, and the case ultimately settled for a lesser amount, according to Ms. Flynn.

An over-the-top wardrobe is just one way that physicians can negatively influence jurors during legal trials. From subtle facial expressions to sudden outbursts to downright rudeness, attorneys have witnessed countless examples of physicians sabotaging their own trials. Legal experts say the cringeworthy experiences are good reminders that jurors are often judging more than just evidence.  

“The minute you enter the courthouse, jurors or potential jurors are sizing you up,” says health law attorney Michael Clark, of Womble Bond Dickinson (US) LLP, based in Houston. “The same phenomenon occurs in a deposition. Awareness of how you are being assessed at all times, and the image that is needed, is important since a negative impression by jurors can have a detrimental effect on a physician’s case.”
 

Juror: We didn’t like the doctor’s shoes

In another case, attorneys warned a physician defendant against dressing in his signature wardrobe during his trial. Against their advice, the doctor showed up daily to his trial in bright pastel, monochromatic suits with matching Gucci-brand shoes, said medical liability defense attorney Meredith C. Lander, of Kaufman Borgeest & Ryan LLP, based in Connecticut. On the witness stand, the doctor was long-winded and wasn’t “terribly likable,” Ms. Lander said.

However, the evidence weighed in the physician’s favor, and there was strong testimony by defense experts. The physician won the case, Ms. Lander said, but after the verdict, the jury foreperson approached the trial attorney and made some disparaging remarks about the defendant.

“The foreperson said the jury didn’t like the doctor or his ‘Gucci suits and shoes,’ but they believed the experts,” Ms. Lander said.

Disruptive behavior can also harm jurors’ perception of physicians, Ms. Flynn adds. During one instance, a surgeon insisted on sitting next to Ms. Flynn, although she generally requests clients sit in the first row so that jurors are not so focused on their reactions during testimony. The surgeon loudly peppered Ms. Flynn with questions as witnesses testified, prompting a reprimand from the judge.

“The judge admonished the doctor several times and said, ‘Doctor, you’re raising your voice. You’ll get a chance to speak with your attorney during the break,’ ” Ms. Flynn recalled. “The doctor refused to stop talking, and the judge told him in front of the jury to go sit in the back of the courtroom. His reaction was, ‘Why do I have to move?! I need to sit here!’ ”

The surgeon eventually moved to the back of the courtroom and a sheriff’s deputy stood next to him. Testimony continued until a note in the form of a paper airplane landed on the table in front of Ms. Flynn. She carefully crumpled the note and tossed it in the wastebasket. Luckily, this drew a laugh from jurors, she said. 

But things got worse when the surgeon testified. Rather than answer the questions, he interrupted and started telling jurors his own version of events.

“The judge finally said, ‘Doctor, if you don’t listen to your attorney and answer her questions, I’m going to make you get off the stand,’ ” Ms. Flynn said. “That was the most unbelievable, egregious self-sabotage trial moment I’ve ever experienced.”

Fortunately, the physician’s legal case was strong, and the experts who testified drove the defense’s side home, Ms. Flynn said. The surgeon won the case.
 

Attorney: Watch what you say in the elevator

Other, more subtle behaviors – while often unintentional – can also be damaging.

Physicians often let their guard down while outside the courtroom and can unknowingly wind up next to a juror in an elevator or standing in a hallway, said Laura Postilion, a partner at Quintairos, Prieto, Wood & Boyer, P.A., based in Chicago.

“For instance, a doctor is in an elevator and feels that some witness on the stand was lying,” Ms. Postilion said. “They might be very upset about it and start ranting about a witness lying, not realizing there is a juror is in the elevator with you.”

Physicians should also be cautious when speaking on the phone to their family or friends during a trial break.

“At the Daley Center in downtown Chicago, there are these long corridors and long line of windows; a lot of people will stand there during breaks. A doctor may be talking to his or her spouse and saying, ‘Yeah, this juror is sleeping!’ Jurors are [often] looking for drama. They’re looking for somebody letting their guard down. Hearing a doctor speak badly about them would certainly give them a reason to dislike the physician.”

Ms. Postilion warns against talking about jurors in or outside of the courtroom. This includes parking structures, she said.

Physicians can take additional steps to save themselves from negative judgment from jurors, attorneys say. Even before the trial starts, Ms. Postilion advises clients to make their social media accounts private. Some curious jurors may look up a physician’s social media accounts to learn more about their personal life, political leanings, or social beliefs, which could prejudice them against the doctor, she said.

Once on the stand, the words and tone used are key. The last thing a physician defendant wants is to come across as arrogant or condescending to jurors, said medical liability defense attorney Michael Moroney, of Flynn Watts LLC.

“For instance, a defendant might say, ‘Well, let me make this simple for you,’ as if they’re talking to a bunch of schoolchildren,” he said. “You don’t know who’s on the jury. That type of language can be offensive.”

Ms. Lander counsels her clients to refrain from using the common phrase, “honestly,” before answering questions on the stand.

“Everything you’re saying on the stand is presumed to be honest,” she said. “When you start an answer with, ‘Honestly…’ out of habit, it really does undercut everything that follows and everything else that’s already been said. It suggests that you were not being honest in your other answers.”
 

Attitude, body language speak volumes

Keep in mind that plaintiffs’ attorneys will try their best to rattle physicians on the stand and get them to appear unlikeable, says Mr. Clark, the Houston-based health law attorney. Physicians who lose their cool and begin arguing with attorneys play into their strategy.

“Plaintiffs’ attorneys have been trained in ways to get under their skin,” he said. “Righteous indignation and annoyance are best left for a rare occasion. Think about how you feel in a social setting when people are bickering in front of you. It’s uncomfortable at best. That’s how a jury feels too.”

Body language is also important, Mr. Clark notes. Physicians should avoid crossed arms, leaning back and rocking, or putting a hand on their mouth while testifying, he said. Many attorneys have practice sessions with their clients and record the interaction so that doctors can watch it and see how they look.

“Know your strengths and weaknesses,” he said. “Get help from your lawyer and perhaps consultants about how to improve these skills. Practice and preparation are important.”

Ms. Postilion goes over courtroom clothing with physician clients before trial. Anything “too flashy, too high-end, or too dumpy” should be avoided, she said. Getting accustomed to the courtroom and practicing in an empty courtroom are good ways to ensure that a physician’s voice is loud enough and projecting far enough in the courtroom, she adds.

“The doctor should try to be the best version of him- or herself to jurors,” she said. “A jury can pick up someone who’s trying to be something they’re not. A good attorney can help the doctor find the best version of themselves and capitalize on it. What is it that you want the jury to know about your care of the patient? Take that overall feeling and make sure it’s clearly expressed to the jury.”

There’s strong evidence that training parents to guide the development of children with autism reaps consistent benefits, according to a systematic review and meta-analysis of more than 50 high-quality studies.

“Referrals for parent training should now be considered the expected standard for medical practice,” said a member of the research team, Timothy B. Smith, PhD, a professor of psychology at Brigham Young University, Provo, Utah.

Methods and results

The meta-analysis included 54 papers based on randomized clinical trials involving 2,895 children, which compared the effects of various parent interventions with professional treatment, treatment as usual, or being on a wait-list to receive an intervention.

Overall the research team reported “moderately strong” average benefits from the parent-mediated interventions (Hedges’ g, 0.553), indicating a medium effect size. Parent interventions had the greatest effect on outcomes involving positive behavior and social skills (0.603), followed by language and communication (0.545), maladaptive behavior (0.519), and life skills (0.239).

Similar benefits were observed regardless of a child’s age or sex or which parent or parents implemented an intervention. The effects also appeared to be consistent regardless of intervention characteristics, such as the number of training sessions parents received, although the researchers noted that many studies did not provide data on such details.

Paul Carbone, MD, a professor of pediatrics at the University of Utah, Salt Lake City, who was not involved in the review, said it demonstrates that such parental engagement is “vitally important” and pediatricians “should not hesitate to refer interested families.”

Overcoming limitations, future research needs

The research team attempted to overcome limitations with previous reviews by using comprehensive search terms and other methods to identify relevant studies, including some that had not been published. They included only studies that reflect common practice of training multiple parents simultaneously, they wrote.

Dr. Smith noted that long-term outcomes data and further study to compare effects on children with mild, moderate, and severe autism are needed.

Although logic would suggest greater benefits for children with severe disease, there are no data to demonstrate that, he said.

The authors of the study and Dr. Carbone reported no relevant competing interests.

Health concerns about the consumption of artificial sweeteners could be strengthened with the publication of a new study linking their intake to increased risk of heart disease and stroke events.

In this latest large-scale, prospective study of French adults, total artificial sweetener intake from all sources was associated with increased risk overall of cardiovascular and cerebrovascular disease.

The study was published online in the BMJ.

The current study differs from those done previously in that it includes artificial sweetener intake from both food and drinks, whereas previous studies have focused mainly on artificial sweetener content of beverages alone.

“Here we have quantified for the first time the global exposure to artificial sweeteners. This is not just beverages but includes the use of tabletop sweeteners, and other foods that include artificial sweeteners such as yogurts and desserts. This is the first time this information has been correlated to risk of heart disease,” senior author Mathilde Touvier, MD, Sorbonne Paris Nord University, told this news organization.

Just over half of the artificial sweetener intake in the study came from drinks, with the rest coming from tabletop sweeteners and foods.

“We included hard cardio- and cerebrovascular clinical endpoints such as a heart attack or stroke, and our results suggest that the amount of artificial sweetener in less than one can of soda could increase the risk of such events,” Dr. Touvier noted.

“This is an important and statistically significant association which shows robustness in all models after adjusting for many other possible confounding factors,” she said.

“There is now mounting evidence correlating artificial sweeteners to weight gain and heart disease,” she concluded. “My advice would be that we all need to try to limit sugar intake, but we should not consider artificial sweeteners as safe alternatives. Rather, we need to try to reduce our need for a sugary taste in our diet.”

But another leading researcher in the field urges caution in interpreting these results.

John Sievenpiper, MD, departments of nutritional sciences and medicine, University of Toronto, commented: “This paper shows the same relationship seen by many other large prospective cohorts which model the intake of artificial sweeteners as baseline or prevalent exposures.

“These observations are well recognized to be at high risk of residual confounding from behavior clustering and reverse causality in which being at risk for cardiovascular disease causes people to consume artificial sweeteners as a strategy to mitigate this risk as opposed to the other way around.”
 

Risk increased by 9%

The current study included 103,388 French adults from the NutriNet-Sante cohort, of whom 37.1% reported consumption of artificial sweeteners. The sweeteners assessed were mainly aspartame (58% of sweetener intake), acesulfame potassium (29%), and sucralose (10%), with the other 3% made up of various other sweeteners including cyclamates and saccharin.

Results showed that over an average 9 years of follow-up, artificial sweetener intake was associated with a 9% increased risk of cardiovascular or cerebrovascular events, including myocardial infarction, acute coronary syndrome, angioplasty, angina, stroke, or transient ischemic attack, with a hazard ratio of 1.09 (95% confidence interval, 1.01-1.18; P = .03).

The average intake of artificial sweeteners among those who reported consuming them was 42.46 mg/day, which corresponds to approximately one individual packet of tabletop sweetener or 100 mL of diet soda.

“We don’t have enough evidence to work out an amount of artificial sweetener that is harmful, but we did show a dose-effect association, with a higher risk of cardiovascular events with higher consumption,” Dr. Touvier said.

“Higher consumption in this study was a mean of 77 mg/day artificial sweetener, which is about 200 mL of soda – just a bit less than one standard can of soda,” she added.

The absolute incidence rate of cardiovascular or cerebrovascular events in higher consumers was 346 per 100,000 person-years vs. 314 per 100,000 person-years in nonconsumers.

Further analysis suggested that aspartame intake was particularly associated with increased risk of cerebrovascular events, while acesulfame potassium and sucralose were associated with increased coronary heart disease risk.
 

Study strengths

Dr. Touvier acknowledged that dietary studies, which generally rely on individuals self-reporting food and drink intake, are always hard to interpret. But she said this study used a more reliable method of dietary assessment, with repeated 24-hour dietary records, which were validated by interviews with a trained dietitian and against blood and urinary biomarkers.

And whereas residual confounding cannot be totally excluded, she pointed out that models were adjusted for a wide range of potential sociodemographic, anthropometric, dietary, and lifestyle confounders.

Dr. Touvier also noted that cases of cardiovascular disease in the first 2 years of follow-up were excluded to minimize the bias caused by individuals who maybe have switched to artificial sweeteners because of a cardiovascular issue.

“While this study has many strengths, it cannot on its own prove a causal relationship between artificial sweetener and increased cardiovascular risk,” she added. “We need health agencies to examine all the literature in the field. This is however another important piece of evidence.”

Dr. Touvier says that although observational studies have their issues, they will form the basis of the evidence on the effects of artificial sweeteners on health.

“Randomized studies in this area can only really look at short-term outcomes such as weight gain or biomarker changes. So, we will have to use observational studies together with experimental research to build the evidence. This is what happened with cigarette smoking and lung cancer. That link was not established by randomized trials, but by the accumulation of observational and experimental data.”
 

Different artificial sweeteners may be better?

Commenting on the study, Kim Williams Sr., MD, University of Louisville (Ky.), pointed out that this study included artificial sweeteners that increase insulin or decrease insulin sensitivity, and that insulin spikes increase obesity, insulin resistance, hypertension, and atherosclerosis.

“There are some safer artificial sweeteners that do not increase insulin much or at all, such as erythritol, yacon root/yacon syrup, stevia root, but they weren’t included in the analysis,” Dr. Williams added.

Dr. Sievenpiper explained that most studies on artificial sweeteners look at their consumption in isolation without considering how they compare to the intake of the sugars that they are intended to replace.

“The comparator matters as no food is consumed in a vacuum,” he said.

To address this, Dr. Sievenpiper and colleagues have recently published a systematic review and meta-analysis of the prospective cohort study evidence that shows if exposure to artificially sweetened beverages is modeled in substitution for sugar-sweetened beverages, then they are associated with less coronary heart disease, cardiovascular mortality, and all-cause mortality.

On the other hand, if exposure to artificially sweetened beverages is compared with water, then no difference in these outcomes was seen.

“These observations are more biologically plausible, robust, and reproducible and agree with the evidence for the effect of artificial sweeteners on intermediate risk factors in randomized trials,” Dr. Sievenpiper notes.

His group has also recently published a review of randomized studies showing that when compared with sugar-sweetened beverages, intake of artificially sweetened beverages was associated with small improvements in body weight and cardiometabolic risk factors without evidence of harm.

“I think the context provided by these studies is important, and taken together, the totality of the evidence suggests that artificial sweeteners are likely to be a useful tool in sugar reduction strategies,” Dr. Sievenpiper concludes.

The current study was funded by the European Research Council under the European Union’s Horizon 2020 research and innovation program, French National Cancer Institute, French Ministry of Health, IdEx Université de Paris Cité, Bettencourt-Schueller Foundation Research Prize 2021. The authors have disclosed no relevant financial relationships.

“While this study has many strengths, it cannot on its own prove a causal relationship between artificial sweetener and increased cardiovascular risk,” she added. “We need health agencies to examine all the literature in the field. This is however another important piece of evidence.”

Dr. Touvier says that although observational studies have their issues, they will form the basis of the evidence on the effects of artificial sweeteners on health.

“Randomized studies in this area can only really look at short-term outcomes such as weight gain or biomarker changes. So, we will have to use observational studies together with experimental research to build the evidence. This is what happened with cigarette smoking and lung cancer. That link was not established by randomized trials, but by the accumulation of observational and experimental data.”
 

Different artificial sweeteners may be better?

Commenting on the study, Kim Williams Sr., MD, University of Louisville (Ky.), pointed out that this study included artificial sweeteners that increase insulin or decrease insulin sensitivity, and that insulin spikes increase obesity, insulin resistance, hypertension, and atherosclerosis.

“There are some safer artificial sweeteners that do not increase insulin much or at all, such as erythritol, yacon root/yacon syrup, stevia root, but they weren’t included in the analysis,” Dr. Williams added.

Dr. Sievenpiper explained that most studies on artificial sweeteners look at their consumption in isolation without considering how they compare to the intake of the sugars that they are intended to replace.

“The comparator matters as no food is consumed in a vacuum,” he said.

To address this, Dr. Sievenpiper and colleagues have recently published a systematic review and meta-analysis of the prospective cohort study evidence that shows if exposure to artificially sweetened beverages is modeled in substitution for sugar-sweetened beverages, then they are associated with less coronary heart disease, cardiovascular mortality, and all-cause mortality.

On the other hand, if exposure to artificially sweetened beverages is compared with water, then no difference in these outcomes was seen.

“These observations are more biologically plausible, robust, and reproducible and agree with the evidence for the effect of artificial sweeteners on intermediate risk factors in randomized trials,” Dr. Sievenpiper notes.

His group has also recently published a review of randomized studies showing that when compared with sugar-sweetened beverages, intake of artificially sweetened beverages was associated with small improvements in body weight and cardiometabolic risk factors without evidence of harm.

“I think the context provided by these studies is important, and taken together, the totality of the evidence suggests that artificial sweeteners are likely to be a useful tool in sugar reduction strategies,” Dr. Sievenpiper concludes.
