AMSTERDAM — For patients with atopic dermatitis (AD) who responded to the anti–interleukin (IL)–13 monoclonal antibody lebrikizumab in the pivotal trials, the level of response, including 90% skin clearance, has generally remained unchanged among those followed up for an additional 2 years, according to the latest data from an extension study. 

At the end of the maintenance phase of the pivotal trials at 12 months, 84% of the patients enrolled into the extension had clear or almost clear skin, as per the Investigator Global Assessment (IGA). This overall figure as well as the proportion with even better responses have persisted unchanged, reported Diamant Thaçi, MD, PhD, professor and head of the Comprehensive Center for Inflammatory Medicine, University of Lübeck in Germany. 
 

Responses at 3 Years Maintained

“This is really quite remarkable,” Dr. Thaçi said. “Roughly all the patients maintained their response.” These results became even more remarkable when patients were assessed for their use of adjunctive therapy to control flares. 

“Over the whole follow-up, 90% had no need for topical corticosteroids or any other rescue therapy,” Dr. Thaçi reported, providing data from the ADjoin lebrikizumab extension study during a late-breaking news session at the annual meeting of the European Academy of Dermatology and Venereology. 

The patients in ADjoin were enrolled from the pivotal phase 3 ADvocate 1 and 2 trials completed almost 2 years ago and published together in March 2023. Lebrikizumab was approved in the United States in September 2024 for moderate to severe AD in patients aged ≥ 12 years, following previous approvals in Europe in 2023 and in Japan in January 2024.

In these two identical trials with a total of 564 patients, the primary endpoint was an IGA of 0 or 1, signifying clear or almost clear skin. At nearly 40%, the proportion of patients reaching this outcome at 16 weeks was about threefold greater (P < .001) on lebrikizumab than on placebo. The benefit was similar on secondary endpoints, such as 75% improvement in the Eczema Area and Severity Index (EASI75) score. 

At the end of the double-blind, placebo-controlled 16-week phase of the ADvocate 1 and 2 trials, which enrolled adults and adolescents aged ≥ 12 years, responders were enrolled into a maintenance phase in which they were rerandomized to 250 mg lebrikizumab every 2 weeks (Q2W) or every 4 weeks (Q4W). The latter is the approved maintenance dose. 

At the end of the maintenance phase, which lasted another 32 weeks (total exposure of 52 weeks for those initially randomized to lebrikizumab), patients were invited into the ADjoin extension. The only exclusions from the extension were serious adverse events related to lebrikizumab and noncompliance. 
 

Response Curves Appear as Straight Lines

Over the next 2 years of ADjoin, response curves appeared as straight lines not only for the overall response but when patients were stratified for different levels of response at the extension study entry. Specifically, 81.5% and 83.3% had an IGA score of 0 or 1 in the Q2W and Q4W arms at completion of the ADvocate 16-week double-blind phase. At 3 years, the rates were 84.0% and 82.9%, respectively. 

For the subgroup who entered ADjoin with an EASI75 or an EASI90 response, the persistence of this level of response over 2 years was similar, although there was some gain observed among those who entered the trial with an EASI75 response. 

“Not only did these patients maintain their response, but the response on average slowly improved, so that there were more patients with an EASI90 response at the 3-year timepoint,” Dr. Thaçi said.

Of the 181 patients in the ADjoin extension, 82 patients were maintained on Q2W dosing and 99 were maintained on Q4W lebrikizumab. Their mean age was about 35 years, more than half were women, and nearly 40% had severe AD at the time they enrolled in the ADvocate trials. There was essentially no difference in response rates among those in the Q2W and Q4W arms over time in ADjoin. 
 

Side Effect Profile Essentially Unchanged

The side effect and tolerability profiles, which were favorable in the original 16-week placebo-controlled study, have remained unchanged over the subsequent maintenance phase and through the additional 2 years of the ADjoin extension.

“There continued to be reports of conjunctivitis, which is very specific for anti–IL-13 therapies,” Dr. Thaçi said. However, he said that the incidence did not increase over time, and because it was easy to treat, “most patients do not discontinue lebrikizumab for this reason.” Moreover, he said the impression was that “the number of patients experiencing adverse effects has been decreasing over time.” 

Calling these long-term results “very exciting,” Dr. Thaçi called lebrikizumab “a very valuable option for long-term AD care.” 

Asked for his perspective on the results, Jonathan I. Silverberg, MD, PhD, Director of Clinical Research, Department of Dermatology, George Washington University, Washington, DC, said that it is important to study long-term efficacy, and these results are positive. Without direct comparisons to other biologics available for AD, nothing can be implied about the relative efficacy of monoclonal antibodies approved for AD. 

“These data are important both from an efficacy and safety perspective” for those advising patients who need chronic AD treatment, said Dr. Silverberg, who was the principal investigator of the ADvocate trials. 

Earlier this year, 5-year follow-up data were published for dupilumab. Of 326 patients who remained on therapy this long, 220 (67%) maintained an IGA of 0 or 1 at the end of the study. There were no unexpected adverse events, which were generally stable or declined throughout the study. 

Dr. Thaçi has financial relationships with AbbVie, Amgen, Boehringer Ingelheim, Bristol-Myers Squibb, Celltrion, Galderma, Leo Pharma, L’Oreal, Janssen-Cilag, New Bridge, Novartis, Pfizer, Regeneron, Roche, Sanofi, Sun Pharma, UCB, and Vichy. Dr. Silverberg reported financial relationships with more than 40 pharmaceutical companies including those that make drugs for AD.

AMSTERDAM — A proteomics study designed to determine why some patients with atopic dermatitis (AD) respond quickly to dupilumab, others respond more slowly, and the remainder do not respond at all demonstrated that molecular responses in these three groups are very different.

A discovery that could lead to personalizing therapies, the data identified “distinct systemic biomarker profiles,” according to Ester Del Duca, MD, an instructor in the Laboratory of Inflammatory Skin Diseases at the Icahn School of Medicine at Mount Sinai, New York City.

The study was conducted with 67 patients with AD and 16 healthy controls. Serum was collected at two timepoints: An average of 20 weeks after starting dupilumab, then at a mean interval of about 9 months later. At these timepoints, called follow-up 1 and 2, a panel of more than 600 proteins, including unique markers for immunologic, cardiovascular, and neurologic activity, were evaluated.

The criterion for differentiating the three response groups was an Investigator Global Assessment (IGA) score of 0 or 1, signifying clear or almost clear skin (or at least a 2-point IGA reduction from baseline). Early responders were those who met the criterion at both follow-ups, late responders were those who met this criterion only at the second follow-up, and nonresponders never met the criterion.

“There were no significant differences at baseline in clinical severity, past medical history, or patient characteristics,” said Del Duca, who presented these data in a late breaking news session at the European Academy of Dermatology and Venereology (EADV) 2024 Congress.

Of the 67 patients with AD, 39 were early responders, 11 were late responders, and 17 were nonresponders.

The differences in proteomics were marked. For early responders, there was an early normalization of the proteome, reported Del Duca, illustrating the differences in the proteome of the three groups with a color-coded chart of protein up-regulation and down-regulation relative to healthy controls. The normalization of the proteome persisted in early responders when assessed at the second follow-up.

In the late responders, the proteome dysregulation was substantial relative to healthy controls at the first follow-up, but there was considerable improvement by the second follow-up. Although the change at the second follow-up was still not as robust as that seen in the early responders at either follow-up, Del Duca described the proteomic profile as a 45% improvement from the first follow-up.

In contrast, nonresponders showed worsening in their blood proteome from follow-up 1 to 2. Nonresponders at first follow-up showed up-regulation relative to healthy controls for many proteins associated with the Th1 response, such as interferon gamma, CXCL9, and CXCL10, and Th2 response, such as interleukin-4 and Th17/22, and these did not normalize or worsen by the second follow-up.

“Uniquely to nonresponders, key Th1 biomarkers remained significantly up-regulated relative to controls at both follow-up 1 and 2,” with a P value < .05, Del Duca reported.

To achieve normalization of the proteome as defined by healthy controls, both up-regulation and down-regulation of protein activity were required, although more up-regulations than down-regulations were observed.

When evaluating the proteome changes most implicated in immunoregulation, the investigators were able to show a correlation between worsening in the proteome and greater severity of AD as defined by IGA, Eczema Area and Severity Index, and body surface area involvement.

“Spearman analysis revealed strong and positive correlations between improvements in biomarkers at follow-up 1 and 2 with improvements in clinical markers,” Del Duca said. As examples, she noted favorable changes in biomarkers specifically associated with T cells, dendritic cells, and natural killer cells as clinical outcomes improved.

Conversely, the worsening in T-cell activation among nonresponders, particularly Th1 biomarkers, also tracked with increasing AD symptoms over time.

The implications of the research are broad, and most importantly, it shows that therapeutic targets are likely to differ between patients with AD, according to Del Duca. Although proteomic studies have not yet been conducted with other treatments, these might provide further insight about how patients with AD differ in response across other drugs.

This is important work, according to Brigitte Dréno, MD, PhD, head of the Department of Dermatology, Nantes University Hospital in France. As moderator of the late-breaking news session, she suggested that there are many potential messages from these data, not least that treatment of AD likely involves targeting cytokines beyond those affected by dupilumab in at least some patients.

When Dréno asked Del Duca about what could be surmised about changes from baseline before treatment to the first follow-up, Del Duca said that the study was retrospective, so baseline data were not available.

This is an important missing piece of this investigation, according to Dréno.

“As you move this work forward,” she said that it would be “very important” to determine “if there are predictive markers for evaluating which patients will respond.”

This is a small study with many additional variables to consider in order to develop a clinically useful tool, Del Duca noted. However, this work not only has the potential to guide treatment selection but the biomarkers up-regulated in nonresponders are already “suggesting potential targets for refining therapeutic strategies,” she said.

The study received funding from Bristol-Myers Squibb. Del Duca reported no financial relationships with industry. Dréno reported financial relationships with La Roche–Posay, Pierre Fabré, and Galderma.

When Dréno asked Del Duca about what could be surmised about changes from baseline before treatment to the first follow-up, Del Duca said that the study was retrospective, so baseline data were not available.

This is an important missing piece of this investigation, according to Dréno.

“As you move this work forward,” she said that it would be “very important” to determine “if there are predictive markers for evaluating which patients will respond.”

This is a small study with many additional variables to consider in order to develop a clinically useful tool, Del Duca noted. However, this work not only has the potential to guide treatment selection but the biomarkers up-regulated in nonresponders are already “suggesting potential targets for refining therapeutic strategies,” she said.

The study received funding from Bristol-Myers Squibb. Del Duca reported no financial relationships with industry. Dréno reported financial relationships with La Roche–Posay, Pierre Fabré, and Galderma.

Clinicians receive conflicting advice on whether to order blood tests to screen for lipids in children. A new study could add to the confusion. Researchers found that a combination of physical proxy measures such as hypertension and body mass index (BMI) predicted the risk for future cardiovascular events as well as the physical model plus lipid labs, questioning the value of those blood tests.

Some medical organizations advise screening only for high-risk children because more research is needed to define the harms and benefits of universal screening. Diet and behavioral changes are sufficient for most children, and universal screening could lead to false positives and unnecessary further testing, they said.

Groups that favor lipid tests for all children say these measurements detect familial hypercholesterolemia (FH) that would not otherwise be diagnosed, leading to treatment with drugs like statins and a greater chance of preventing cardiovascular disease (CVD) in adulthood.

Researchers from the new study said their findings do not address screenings for FH, which affects 1 in 250 US children and puts them at a risk for atherosclerotic CVD.
 

Recommending Blood Tests in Age Groups

One of the seminal guidelines on screening lipids in children came from the National Heart, Lung, and Blood Institute (NHLBI), which in 2011 recommended children undergo dyslipidemia screening between the ages of 9 and 11 years and again between 17 and 21 years. Children should receive a screening starting at age 2 years if they have a family history of CVD or dyslipidemia or have diabetes, an elevated BMI, or hypertension. The American Academy of Pediatrics shortly followed suit, issuing similar recommendations.

Screening for the two subsets of ages was an expansion from the original 1992 guidelines from the National Cholesterol Education Program, which recommended screening only for children with either a family history of early CVD or elevated total cholesterol levels.

A 2011 panel for the NHLBI said the older approach identified significantly fewer children with abnormal levels of low-density lipoprotein cholesterol (LDL-C) than the addition of two age groups for screening, adding that many children do not have a complete family history. The American College of Cardiology and American Heart Association later supported NHLBI’s stance in their joint guidelines on the management of cholesterol.

Mark Corkins, MD, chair of the AAP’s Committee on Nutrition, told Medscape Medical News that if children are screened only because they have obesity or a family history of FH, some with elevated lipid levels will be missed. For instance, studies indicate caregiver recall of FH often is inaccurate, and the genetic disorder that causes the condition is not related to obesity.

“The screening is to find familial hypercholesterolemia, to try to find the ones that need therapy,” that would not be caught by the risk-based screening earlier on in childhood, Corkins said.
 

Only Screen Children With Risk Factors

But other groups do not agree. The US Preventive Services Task Force (USPSTF) found insufficient evidence to recommend for or against screening for lipid disorders in asymptomatic children and teens.

The group also said it found inadequate evidence that lipid-lowering interventions in the general pediatric population lead to reductions in cardiovascular events or all-cause mortality once they reached adulthood. USPSTF also raised questions about the safety of lipid-lowering drugs in children.

“The current evidence is insufficient to assess the balance of benefits and harms of screening for lipid disorders in children and adolescents 20 years or younger,” the panel wrote.

The American Academy of Family Physicians supports USPSTF’s recommendations.
 

Low Rate of Screening

While the uncertainty over screening in children continues, the practice has been adopted by a minority of clinicians.

A study published in JAMA Network Open in July found 9% of 700,000 9- to 11-year-olds had a documented result from a lipid screening. Among more than 1.3 million 17- to 21-year-olds, 13% had received a screening.

As BMI went up, so did screening rates. A little over 9% children and teens with a healthy weight were screened compared with 14.7% of those with moderate obesity and 21.9% of those with severe obesity.

Among those screened, 32.3% of 9- to 11-year-olds and 30.2% of 17- to 21-year-olds had abnormal lipid levels, defined as having one elevated measure out of five, including total cholesterol of 200 mg/dL or higher or LDL-C levels of 130 mg/dL or higher.

Justin Zachariah, MD, MPH, an associate professor of pediatrics-cardiology at Baylor College of Medicine in Houston, spoke about physicians screening children based only on factors like obesity during a presentation at the recent annual meeting of the American Academy of Pediatrics. He cited research showing roughly one in four children with abnormal lipids had a normal weight.

If a clinician is reserving a lipid screening for a child who is overweight or has obesity, “you’re missing nearly half the problem,” Zachariah said during his presentation.

One reason for the low rate of universal screening may be inattention to FH by clinicians, according to Samuel S. Gidding, MD, a professor in the Department of Genomic Health at Geisinger College of Health Sciences in Bridgewater Corners, Vermont.

For instance, a clinician has only a set amount of time during a well-child visit and other issues may take precedence, “so it doesn’t make sense to broach preventive screening for something that could happen 30 or 40 years from now, vs this [other] very immediate problem,” he said.

Clinicians “are triggered to act on the LDL level, but don’t think about FH as a possible diagnosis,” Gidding told Medscape Medical News.

Another barrier is that in some settings, caregivers must take children and teens to another facility on a different day to fulfill an order for a lipid test.

“It’s reluctance of doctors to order it, knowing patients won’t go through with it,” Gidding said.

Gidding is a consultant for Esperion Therapeutics. Other sources in this story reported no relevant financial conflicts of interest.

Katie Sullivan, DNP, FNP-C, is publicizing her own challenge with updating an insulin pump as part of an effort to bring an end to the biannual seasonal clock changes in the United States.

On March 10, 2024, Sullivan, who works in the Endocrinology Clinic, Michigan State University, East Lansing, Michigan, mistakenly reversed the AM and PM settings while adjusting her own insulin pump. Sullivan, who has type 1 diabetes, noticed several hours later that her blood glucose levels had become higher than usual and was surprised to see her pump showed sleep mode during the day.

She was able to address this glitch before going to sleep and thus “escaped a potential occurrence of nocturnal hypoglycemia,” Sullivan and her colleague, Saleh Aldasouqi, MD, wrote in a September commentary in the journal Clinical Diabetes.

The risk of daylight saving time (DST) changes for people with insulin pumps is well known. Aldasouqi himself raised it in a 2014 article in the Journal of Diabetes Science and Technology.

Medtronic Inc., the leading maker of insulin pumps, told this news organization in an email that it intends for future devices to automate DST changes. The company did not provide any further details on when such changes would happen.

For now, Medtronic and other makers of insulin pumps join in twice-a-year efforts to remind people they need to update their devices to adjust for DST changes. They will need to gear up these outreach campaigns, which include social media posts, again ahead of the end of DST on November 3, when clocks shift back an hour. Diabetes clinics and hospitals also send notes to patients.

Even so, people will fail to make this change or to do it correctly.

“Despite our efforts to educate our patients about DST glitches, we have detected incorrect time settings in some of our patients’ insulin pumps after the DST changes in the fall and spring and occasional cases of incorrect insulin dosing, resulting in hyperglycemia or hypoglycemia,” Sullivan and Aldasouqi wrote in their article.

The US Food and Drug Administration (FDA) database of injuries and mishaps with devices contains many reports about patients not adjusting their insulin pumps for DST.

Known as Manufacturer and User Facility Device Experience (MAUDE), this database does not provide identifying details about the patients. Instead, the reports contain only a few lines describing what happened. In many cases, people were able to easily resolve their temporary glycemic issues and then set their devices to the correct time.

But some of the MAUDE reports tell of more severe consequences, with people ending up in emergency rooms because they did not adjust their insulin pumps for DST.

Among these is a report about a November 2022 incident, where a patient suffered due to what appeared to be inaccurate continuous glucose monitor readings, combined with the effects of an insulin pump that had not been updated for a DST change.

Although that patient’s mother was available to assist and the patient consumed three dextrose candies, the patient still reportedly lost consciousness and experienced tremors. That led to hospitalization, where the patient was treated with intravenous saline, intravenous insulin, saline fluids, and insulin fluids. The patient left the hospital with “the issue resolved and no permanent damage” but then switched to another method of insulin therapy, the MAUDE report said.

It’s unclear how often DST changes lead to problems with insulin pumps, reflecting difficulties in tracking flaws and glitches in medical devices, Madris Kinard, the chief executive officer and founder of Device Events, told this news organization.

The FDA relies heavily on passive surveillance, gathering MAUDE reports submitted by companies, clinicians, and patients. That means many cases likely are missed, said Kinard who earlier worked as an analyst at the FDA, updating processes and systems to help identify risky devices.

For example, Sullivan told this news organization she had not filed a report for her incident with the insulin pump.
 

Permanent Standard Time?

Many clinicians, including Aldasouqi and Sullivan, argue a better solution to these challenges would be to end DST.

In their Clinical Diabetes article, they also cited other health risks associated with clock changes such as fatigue, headache, and loss of attention and alertness that can result in injuries.

But a permanent time change is a “politically charged issue, and it continues to be debated nationally and at the state level,” they wrote.

At least 30 states also considered measures this year related to DST, according to the National Conference of State Legislatures. A pending Senate bill intended to make DST permanent has the support of 8 Democrats and 11 Republicans, including Sen. Tommy Tuberville (R-Ala).

“It’s amazing how many phone calls we get over this one topic. People across America agree that changing our clocks back and forth twice a year really makes no sense,” Tuberville said last year on the Senate floor. “People call and say they’re just sick of it.”

These federal and state efforts have stalled to date on the key question of whether to make either standard time or DST permanent, the National Conference of State Legislatures noted. A shift to permanent DST might have benefits for some agricultural and recreational industries, but many physicians say it would be bad for people’s health.

The American Academy of Sleep Medicine (AASM) argues strongly for moving to permanent standard time. In a position statement published in the Journal of Clinical Sleep Medicine, the group said the acute transitions from standard time to DST pose harms, citing research indicating increased risks for adverse cardiovascular events, mood disorders, and motor vehicle crashes.

The solution is to end shifts in time and opt for standard time, which best aligns with the human biological clock, AASM said.

AASM noted that there already was a failed experiment in the United States with a shift to permanent DST. Congress established this in response to the 1973 OPEC oil embargo, expecting that allowing more evening hours with light would lead to energy savings. That didn’t pay off in the expected reduction in energy and the policy was highly unpopular, especially in rural areas, AASM said.

“After a single winter, the policy was reversed by an overwhelming congressional majority,” wrote Muhammad Adeel Rishi, MD, and other authors of the statement. “The unpopularity of the act was likely because despite greater evening light, the policy resulted in a greater proportion of days that required waking up on dark mornings, particularly in the winter.”

Karin G. Johnson, MD, professor of neurology at the UMass Chan School of Medicine, Worcester, Massachusetts, told this news organization that a shift to permanent DST would rob many people of the signals their bodies need for sleep.

“Sunrises and sunsets are later and that creates a desire for our body to stay up later and have more trouble getting up in the morning,” Johnson said. “You’re all but making it impossible for certain segments of the population to get enough sleep” with permanent DST.

Johnson, Sullivan, and Aldasouqi had no relevant financial disclosures.

The patient left the hospital with “the issue resolved and no permanent damage” but then switched to another method of insulin therapy, the MAUDE report said.

It’s unclear how often DST changes lead to problems with insulin pumps, reflecting difficulties in tracking flaws and glitches in medical devices, Madris Kinard, the chief executive officer and founder of Device Events, told this news organization.

The FDA relies heavily on passive surveillance, gathering MAUDE reports submitted by companies, clinicians, and patients. That means many cases likely are missed, said Kinard who earlier worked as an analyst at the FDA, updating processes and systems to help identify risky devices.

For example, Sullivan told this news organization she had not filed a report for her incident with the insulin pump.
 

Permanent Standard Time?

Many clinicians, including Aldasouqi and Sullivan, argue a better solution to these challenges would be to end DST.

In their Clinical Diabetes article, they also cited other health risks associated with clock changes such as fatigue, headache, and loss of attention and alertness that can result in injuries.

But a permanent time change is a “politically charged issue, and it continues to be debated nationally and at the state level,” they wrote.

At least 30 states also considered measures this year related to DST, according to the National Conference of State Legislatures. A pending Senate bill intended to make DST permanent has the support of 8 Democrats and 11 Republicans, including Sen. Tommy Tuberville (R-Ala).

“It’s amazing how many phone calls we get over this one topic. People across America agree that changing our clocks back and forth twice a year really makes no sense,” Tuberville said last year on the Senate floor. “People call and say they’re just sick of it.”

These federal and state efforts have stalled to date on the key question of whether to make either standard time or DST permanent, the National Conference of State Legislatures noted. A shift to permanent DST might have benefits for some agricultural and recreational industries, but many physicians say it would be bad for people’s health.

The American Academy of Sleep Medicine (AASM) argues strongly for moving to permanent standard time. In a position statement published in the Journal of Clinical Sleep Medicine, the group said the acute transitions from standard time to DST pose harms, citing research indicating increased risks for adverse cardiovascular events, mood disorders, and motor vehicle crashes.

The solution is to end shifts in time and opt for standard time, which best aligns with the human biological clock, AASM said.

AASM noted that there already was a failed experiment in the United States with a shift to permanent DST. Congress established this in response to the 1973 OPEC oil embargo, expecting that allowing more evening hours with light would lead to energy savings. That didn’t pay off in the expected reduction in energy and the policy was highly unpopular, especially in rural areas, AASM said.

“After a single winter, the policy was reversed by an overwhelming congressional majority,” wrote Muhammad Adeel Rishi, MD, and other authors of the statement. “The unpopularity of the act was likely because despite greater evening light, the policy resulted in a greater proportion of days that required waking up on dark mornings, particularly in the winter.”

Karin G. Johnson, MD, professor of neurology at the UMass Chan School of Medicine, Worcester, Massachusetts, told this news organization that a shift to permanent DST would rob many people of the signals their bodies need for sleep.

“Sunrises and sunsets are later and that creates a desire for our body to stay up later and have more trouble getting up in the morning,” Johnson said. “You’re all but making it impossible for certain segments of the population to get enough sleep” with permanent DST.

Johnson, Sullivan, and Aldasouqi had no relevant financial disclosures.

In several countries, including China, Mexico, and the United States, the incidence of type 2 diabetes now exceeds that of type 1 diabetes among patients younger than 20 years.

“This is an emerging epidemic,” said Orit Pinhas-Hamiel, MD, director of the Pediatric Endocrinology and Diabetes Unit at Sheba Medical Center in Ramat Gan, Israel, at the annual meeting of the European Association for the Study of Diabetes, noting that these young patients, most with obesity, exhibit a significantly higher incidence of complications than adults with type 2 diabetes or young people with type 1 diabetes.

In 2017-2018, the incidence of type 2 diabetes among patients aged 15-19 years (19.7 per 100,000) surpassed that of type 1 diabetes (14.6 per 100,000), according to data from the United States.

“This is the first time that the incidence of type 2 diabetes has exceeded that of type 1 among youth,” said Pinhas-Hamiel. A review of 2021 published a few months ago highlighted this surge, with countries like China, India, the United States, Brazil, and Mexico leading the way.
 

SEARCH and TODAY

The SEARCH for Diabetes in Youth study, which was launched in 2000, is a multicenter observational study in the United States aimed at estimating the prevalence, incidence, and complications of types 1 and 2 diabetes among young patients. The Treatment Options for Type 2 Diabetes in Adolescents and Youth (TODAY) study is an interventional study focusing on adolescents with type 2 diabetes to evaluate the effectiveness of various treatment options.

“Diabesity” — the dual global epidemic of obesity and type 2 diabetes — has visible consequences from the moment of diagnosis, including hypertension. In the TODAY study, 11.6% adolescents had hypertension at diagnosis. A study conducted in Hong Kong involving 391 children younger than 18 years revealed that 22.5% had hypertension. In SEARCH, 27% young patients diagnosed with type 2 diabetes for 1.5 years had hypertension.

In addition, the SEARCH study found that 27% young individuals had low levels of high-density lipoprotein cholesterol, while 25% had high triglyceride levels, at 1.5 years after diagnosis.

Overall, the cumulative incidence of long-term diabetic complications was assessed in 500 adolescents participating in TODAY (mean age, 26.4 ± 2.8 years; mean time since diagnosis, 13.3 ± 1.8 years). The initial prevalence was 19.2%, while the cumulative incidence rose to 67.5% after 15 years of follow-up.

For dyslipidemia, the initial prevalence was 20.8%, with a cumulative incidence of 51.6%. The incidence of diabetic nephropathy was 54.8% and neuropathies was 32.4%. The prevalence of retinopathy was 13.7% for the period 2010-2011 and 51% for 2017-2018.

At least one complication was observed in 60.1% participants and at least two in 28.4%. As expected, risk factors for developing complications included belonging to a racial or ethnic minority, hyperglycemia, hypertension, and dyslipidemia.

“Among those who developed type 2 diabetes in adolescence, the risk for complications, including microvascular complications, has continuously increased and affected most participants in young adulthood,” said Pinhas-Hamiel.

At the same time, the rate of treatment with lipid-lowering and antihypertensive medications remains low among young people with type 2 diabetes. The management of dyslipidemia is suboptimal, with only 5% young patients with diabetes and dyslipidemia receiving appropriate medications. Furthermore, treatment adherence is lacking. In the TODAY cohort, for example, only one third of participants with high levels of low-density lipoprotein cholesterol were on lipid-lowering medications, and only half of the young patients with hypertension were taking antihypertensives.
 

Focus on Diabetic Nephropathy

Diabetic kidney disease is the leading microvascular complication of type 2 diabetes in adolescents. It is associated with rapid progression and poor prognosis. The natural history begins with hyperfiltration: A consequence of obesity and impaired glucose tolerance. Structural renal changes can be detected as early as 1.5 years after diagnosis.

The second stage is characterized by a reduction in the glomerular filtration rate. At this stage, “the structural changes in the kidney are typical but often present,” said Pinhas-Hamiel, making this period critical for reducing risk factors.

In TODAY, the cumulative incidence of diabetic nephropathy was 54.8%. The prevalence at inclusion was 8%. In SEARCH, after 8 years, the prevalence of diabetic kidney disease was 19.9% among adolescents with type 2 diabetes vs 5.8% among those with type 1 diabetes. A pre-analysis revealed that the overall prevalence of macroalbuminuria among 730 children and adolescents with type 2 diabetes was 3.8%. The ages at diagnosis of type 2 diabetes ranged from 6.5 to 21 years, and the duration of the disease varied from diagnosis to 15 years after.

Diabetic retinopathy was present in 50% participants in the TODAY study at age 25 years (ie, after 12 years of disease). In SEARCH, 56% young patients had diabetic retinopathy after 12.5 years of diabetes. In addition, in the same study, the prevalence of peripheral neuropathy, assessed after 8 years, was 22% among adolescents with type 2 diabetes vs 7% among those with type 1 diabetes.
 

Cardiovascular Autonomic Neuropathy

A decrease in heart rate variability was observed in 47% young patients with type 2 diabetes after an average disease duration of only 1.7 years. In SEARCH, the prevalence of cardiovascular autonomic neuropathy, assessed after 8 years of disease, was 17% in adolescents with type 2 diabetes versus 12% in those with type 1 diabetes.

Overall, 7.1% participants had three complications: nephropathy, retinopathy, and neuropathy. The cumulative incidence of microvascular complications was 80%.

Moreover, A1c levels deteriorated progressively throughout the follow-up period. Approximately 45% participants had an A1c of at least 10%, and 20% were between 8% and 10%. Body mass index consistently remained between 35 and 37.5.

Young patients with type 2 diabetes exhibit endothelial dysfunction, increased carotid intima-media thickness, elevated arterial stiffness, left ventricular hypertrophy, diastolic dysfunction, and reduced maximal exercise capacity. All these factors predict cardiovascular morbidity and mortality.

In TODAY, 17 serious cardiovascular events were recorded, including four myocardial infarctions, six cases of congestive heart failure, three coronary events, and four strokes.

In an analysis of the TODAY and SEARCH studies, although the average duration of diabetes was similar, complications were more frequent among young patients with type 2 diabetes than among those with type 1 diabetes. Microvascular complications were 2.5 times more frequent, and macrovascular complications were four times more frequent.

In SEARCH, excessive mortality was observed among young adults for each type of diabetes. Differences in risk were associated with diabetes type, age, race/ethnicity, and sex. Mortality ratios were 1.5 and 2.3 for types 1 and 2 diabetes, respectively.

Women had higher mortality rates than men. Diabetes was the underlying cause of death in 9.1% cases, which was comparable to cardiovascular diseases or cancer (10.9%). According to a life expectancy model, young patients with type 2 diabetes lose about 15 years of life.
 

Eating Disorders and Depression

Beyond these complications, other issues are often present among adolescents with type 2 diabetes. Approximately 50% have eating disorders (compared with 21% among those with type 1 diabetes), 19.3% report depressive symptoms, and 18.9% have expressed thoughts of self-harm. In addition, 19.6% have polycystic ovary syndrome. Z-scores for bone mineral density at the femoral neck and lumbar spine were significantly lower in adolescents with type 2 diabetes than in healthy peers. The presence of metabolic dysfunction–associated fatty liver disease is also more pronounced.

“The recent approvals of new pharmacological interventions for weight loss and improved glycemic control in adolescents offer hope. We hope that, over the next decade, the prevalence of complications among these young patients with type 2 diabetes will decline. In the meantime, a proactive approach is essential to prevent complications related to type 2 diabetes in these youth,” Pinhas-Hamiel concluded.

“Because you know I’m all about that base, ‘bout that base, no acid.” 

Do those words sound familiar? That’s because they’re the lyrics to Meghan Trainor’s “All About That Bass,” slightly tweaked to function as a medical study tool.

Early in med school, J.C. Sue, DO, now a family medicine physician, refashioned the song’s words to help him prepare for a test on acid extruders and loaders. Sue’s version, “All About That Base,” contained his lecture notes. During the exam, he found himself mentally singing his parody and easily recalling the information. Plus, the approach made cramming a lot more palatable.

Sound silly? It’s not. Sue’s approach is backed up by science. A significant body of research has illuminated the positive association between music and memory. And the benefits last. Recently, a 2024 study from Canada suggested that musical memory doesn’t decrease with age. And a 2023 study revealed music was a better cue than food for helping both young and older adults recall autobiographical memories.

Inspired by his success, Sue gave popular songs a medical spin throughout his medical training. “There’s no rule that says studying must be boring, tedious, or torturous,” Sue said. “If you can make it fun, why not?”

Sue isn’t alone. Many physicians say that writing songs, listening to music, or playing instruments improves their focus, energy, and work performance, along with their confidence and well-being.

Why does music work so well?
 

Tune Your Brain to Work With Tunes

Remember learning your ABCs to the tune of “Twinkle, Twinkle, Little Star?” (Or ask any Gen X person about Schoolhouse Rock.)

In the classroom, music is an established tool for teaching kids, said Ruth Gotian, EdD, MS, chief learning officer and associate professor of education in anesthesiology at Weill Cornell Medicine, New York City. But she said musical strategies make studying easier for adults, too, no matter how complex the material.

Christopher Emdin, PhD, Maxine Greene chair and professor of science education at Teachers College, Columbia University, New York City, shares Gotian’s view. When teaching science, engineering, technology, and mathematics (STEM) subjects to high school kids, he challenged them to write raps about the new concepts.

That’s when he saw visible results: As his students took exams, Emdin noticed them nodding and moving their mouths and heads.

“They were literally performing the songs they’d written for themselves,” Emdin said. “When you write a song to a beat, it’s almost like your heartbeat. You know it so well; you can conjure up your memories by reciting the lyrics.”

If songwriting isn’t in your repertoire, you’ll be glad to hear that just listening to music while studying can help with retention. “Music keeps both sides of the brain stimulated, which has been shown to increase focus and motivation,” explained Anita A. Paschall, MD, PhD, Medical School and Healthcare Admissions expert/director of Medical School and Healthcare Admissions at The Princeton Review.
 

‘Mind on a Permanent Vacation’

Paschall’s enthusiasm comes from personal experience. While preparing for her board exams, Jimmy Buffet’s catalog was her study soundtrack. “His songs stayed in my mind. I could hum along without having to think about it, so my brain was free to focus,” she recalled.

Because Paschall grew up listening to Buffet’s tunes, they also evoked relaxing moments from her earlier life, which she found comforting and uplifting. The combination helped make long, intense study sessions more pleasant. After all, when you’re “wasting away again in Margaritaville,” how can you feel stressed and despondent?

Alexander Remy Bonnel, MD, clinical assistant professor of medicine at the University of Pennsylvania and a physician at Pennsylvania Hospital, both in Philadelphia, found ways to incorporate both auditory and visual stimuli in his med school study routine. He listened to music while color-coding his notes to link both cues to the information. As with Paschall, these tactics helped reduce the monotony of learning reams of material.

That gave Bonnel an easy way to establish an important element for memory: Novelty.

“When you need to memorize so many things in a short amount of time, you’re trying to vary ways of internalizing information,” he observed. “You have a higher chance of retaining information if there’s something unique about it.”
 

Building Team Harmony

“Almost every single OR I rotated through in med school had music playing,” Bonnel also recalled. Furthermore, he noticed a pattern to the chosen songs: Regardless of their age, surgeons selected playlists of tunes that had been popular when they were in their 20s. Those golden oldies, from any era, could turn the OR team into a focused, cohesive unit.

Kyle McCormick, MD, a fifth-year resident in orthopedic surgery at New York–Presbyterian Hospital, Columbia University Irving Medical Center, New York City, has also noticed the ubiquity of background music in ORs. Her observation: Surgeons tend to choose universally popular, inoffensive songs, like tracks from Hall & Oates and Fleetwood Mac.

This meshes with the results of a joint survey of nearly 700 surgeons and other healthcare professionals conducted by Spotify and Figure 1 in 2021; 90% of the surgeons and surgical residents who responded said they listened to music in the OR. Rock and pop were the most popular genres, followed by classical, jazz, and then R&B.

Regardless of genre, music helped the surgical teams focus and feel less tense, the surgeons reported. But when training younger doctors, managing complications, or performing during critical points in surgery, many said they’d lower the volume.

Outside the OR, music can also help foster connection between colleagues. For Lawrence C. Loh, MD, MPH, adjunct professor at Dalla Lana School of Public Health at the University of Toronto in Ontario, Canada, playing guitar and piano has helped him connect with his staff. “I’ve played tunes at staff gatherings and recorded videos as encouragement during the emergency response for COVID-19,” he shared.

In his free time, Loh has also organized outings to his local pub’s weekly karaoke show for more than a decade. His goal: “Promote social cohesion and combat loneliness among my friend and social networks.”
 

Get Your Own Musical Boost

If all this sounds like music to your ears, here are some ways to try it yourself.

Find a study soundtrack. When choosing study music, follow Paschall’s lead and pick songs you know well so they’ll remain in the background. Also, compile a soundtrack you find pleasant and mood-boosting to help relieve the tedium of study and decrease stress.

Keep in mind that we all take in and process information differently, said Gotian. So background music during study sessions might not work for you. According to a 2017 study published in Frontiers in Psychology, it can be a distraction and impair learning for some. Do what works.

Get pumped with a “walkup song.” What songs make you feel like you could conquer the world? asked Emdin. Or what soundtrack would be playing if you were ascending a stage to accept an award or walking out to take the mound in the ninth inning? Those songs should be on what he calls your “superhero” or “walkup” playlist. His prescription: Tune in before you begin your workday or start a challenging procedure.

Paschall agrees and recommends her students and clients listen to music before sitting down for an exam. Forget reviewing flashcards for the nth time, she counseled. Putting on headphones (or earbuds) will put you in a “better headspace.”

Choose work and play playlists. As well as incorporating tunes in your clinic or hospital, music can help relieve stress at the end of the workday. “Medical culture can often be detrimental to doctors’ health,” said Sue, who credits music with helping him maintain equanimity.

Bonnel can relate. Practicing and performing with the Penn Medicine Symphony Orchestra offers him a sense of community and relief from the stress of modern life. “For 2 hours every Tuesday, I put my phone away and just play,” he said. “It’s nice to have those moments when I’m temporarily disconnected and can just focus on one thing: Playing.”
 

Scale Up Your Career

Years after med school graduation, Sue still recalls many of the tunes he wrote to help him remember information. When he sings a song in his head, he’ll get a refresher on pediatric developmental milestones, medication side effects, anatomical details, and more, which informs the treatment plans he devises for patients. To help other doctors reap these benefits, Sue created the website Tune Rx, a medical music study resource that includes many of the roughly 100 songs he’s written.

Emdin often discusses his musical strategies during talks on STEM education. Initially, people are skeptical, he said. But the idea quickly rings a bell for audience members. “They come up to me afterward to share anecdotes,” Emdin said. “If you have enough anecdotes, there’s a pattern. So let’s create a process. Let’s be intentional about using music as a learning strategy,” he urged.

“Because you know I’m all about that base, ‘bout that base, no acid.” 

Do those words sound familiar? That’s because they’re the lyrics to Meghan Trainor’s “All About That Bass,” slightly tweaked to function as a medical study tool.

Early in med school, J.C. Sue, DO, now a family medicine physician, refashioned the song’s words to help him prepare for a test on acid extruders and loaders. Sue’s version, “All About That Base,” contained his lecture notes. During the exam, he found himself mentally singing his parody and easily recalling the information. Plus, the approach made cramming a lot more palatable.

Sound silly? It’s not. Sue’s approach is backed up by science. A significant body of research has illuminated the positive association between music and memory. And the benefits last. Recently, a 2024 study from Canada suggested that musical memory doesn’t decrease with age. And a 2023 study revealed music was a better cue than food for helping both young and older adults recall autobiographical memories.

Inspired by his success, Sue gave popular songs a medical spin throughout his medical training. “There’s no rule that says studying must be boring, tedious, or torturous,” Sue said. “If you can make it fun, why not?”

Sue isn’t alone. Many physicians say that writing songs, listening to music, or playing instruments improves their focus, energy, and work performance, along with their confidence and well-being.

Why does music work so well?
 

Tune Your Brain to Work With Tunes

Remember learning your ABCs to the tune of “Twinkle, Twinkle, Little Star?” (Or ask any Gen X person about Schoolhouse Rock.)

In the classroom, music is an established tool for teaching kids, said Ruth Gotian, EdD, MS, chief learning officer and associate professor of education in anesthesiology at Weill Cornell Medicine, New York City. But she said musical strategies make studying easier for adults, too, no matter how complex the material.

Christopher Emdin, PhD, Maxine Greene chair and professor of science education at Teachers College, Columbia University, New York City, shares Gotian’s view. When teaching science, engineering, technology, and mathematics (STEM) subjects to high school kids, he challenged them to write raps about the new concepts.

That’s when he saw visible results: As his students took exams, Emdin noticed them nodding and moving their mouths and heads.

“They were literally performing the songs they’d written for themselves,” Emdin said. “When you write a song to a beat, it’s almost like your heartbeat. You know it so well; you can conjure up your memories by reciting the lyrics.”

If songwriting isn’t in your repertoire, you’ll be glad to hear that just listening to music while studying can help with retention. “Music keeps both sides of the brain stimulated, which has been shown to increase focus and motivation,” explained Anita A. Paschall, MD, PhD, Medical School and Healthcare Admissions expert/director of Medical School and Healthcare Admissions at The Princeton Review.
 

‘Mind on a Permanent Vacation’

Paschall’s enthusiasm comes from personal experience. While preparing for her board exams, Jimmy Buffet’s catalog was her study soundtrack. “His songs stayed in my mind. I could hum along without having to think about it, so my brain was free to focus,” she recalled.

Because Paschall grew up listening to Buffet’s tunes, they also evoked relaxing moments from her earlier life, which she found comforting and uplifting. The combination helped make long, intense study sessions more pleasant. After all, when you’re “wasting away again in Margaritaville,” how can you feel stressed and despondent?

Alexander Remy Bonnel, MD, clinical assistant professor of medicine at the University of Pennsylvania and a physician at Pennsylvania Hospital, both in Philadelphia, found ways to incorporate both auditory and visual stimuli in his med school study routine. He listened to music while color-coding his notes to link both cues to the information. As with Paschall, these tactics helped reduce the monotony of learning reams of material.

That gave Bonnel an easy way to establish an important element for memory: Novelty.

“When you need to memorize so many things in a short amount of time, you’re trying to vary ways of internalizing information,” he observed. “You have a higher chance of retaining information if there’s something unique about it.”
 

Building Team Harmony

“Almost every single OR I rotated through in med school had music playing,” Bonnel also recalled. Furthermore, he noticed a pattern to the chosen songs: Regardless of their age, surgeons selected playlists of tunes that had been popular when they were in their 20s.

A 3-year-old presents to my clinic for evaluation of a possible autism spectrum disorder/difference. He has a history of severe emotional dysregulation, as well as reduced social skills and multiple sensory sensitivities. When I enter the exam room he is watching videos on his mom’s phone, and has some difficulty transitioning to play with toys when I encourage him to do so. He is eventually able to cooperate with my testing, though a bit reluctantly, and scores within the low average range for both language and pre-academic skills. His neurologic exam is within normal limits. He utilizes reasonably well-modulated eye contact paired with some typical use of gestures, and his affect is moderately directed and reactive. He displays typical intonation and prosody of speech, though engages in less spontaneous, imaginative, and reciprocal play than would be expected for his age. His mother reports decreased pretend play at home, minimal interest in toys, and difficulty playing cooperatively with other children.

Upon further history, it becomes apparent that the child spends a majority of his time on electronic devices, and has done so since early toddlerhood. Further dialogue suggests that the family became isolated during the COVID-19 pandemic, and has not yet re-engaged with the community in a meaningful way. The child has had rare opportunity for social interactions with other children, and minimal access to outdoor play. His most severe meltdowns generally involve transitions away from screens, and his overwhelmed parents often resort to use of additional screens to calm him once he is dysregulated.

Oregon Health &amp; Science University (OHSU)

At the end of the visit, through shared decision making, we agree that enrolling the child in a high-quality public preschool will help parents make a concerted effort towards a significant reduction in the hours per day in which the child utilizes electronic devices, while also providing him more exposure to peers. We plan for the child to return in 6 months for a re-evaluation around social-emotional skills, given his current limited exposure to peers and limited “unplugged” play-time.
 

Overutilization of Electronic Devices

As clinicians, we can all see how pervasive the use of electronic devices has become in the lives of the families we care for, as well as in our own lives, and how challenging some aspects of modern parenting have become. The developmental impact of early and excessive use of screens in young children is well documented,¹ but as clinicians it can be tricky to help empower parents to find ways to limit screen time. When parents use screens to comfort and amuse their children during a clinic visit, this situation may serve as an excellent opportunity for a meaningful and respectful conversation around skill deficits which can result from overutilization of electronic devices in young children.

One scenario I often encounter during my patient evaluations as a developmental and behavioral pediatrician is children begging their parents for use of their phone throughout their visits with me. Not infrequently, a child is already on a screen when I enter the exam room, even when there has been a minimal wait time, which often leads to some resistance on behalf of the child as I explain to the family that a significant portion of the visit involves my interactions with the child, testing the child, and observing their child at play. I always provide ample amounts of age-appropriate art supplies, puzzles, fidgets, building toys, and imaginative play items to children during their 30 to 90 minute evaluations, but these are often not appealing to children when they have been very recently engaged with an electronic device. At times I also need to ask caretakers themselves to please disengage from their own electronic devices during the visit so that I can involve them in a detailed discussion about their child.

One challenge with the practice of allowing children access to entertainment on their parent’s smartphones in particular, lies in the fact that these devices are almost always present, meaning there is no natural boundary to inhibit access, in contrast to a television set or stationary computer parked in the family living room. Not dissimilar to candy visible in a parent’s purse, a cell phone becomes a constant temptation for children accustomed to utilizing them at home and public venues, and the incessant begging can wear down already stressed parents.

Children can become conditioned to utilize the distraction of screens to avoid feelings of discomfort or stress, and so can be very persistent and emotional when asking for the use of screens in public settings. Out in the community, I very frequently see young children and toddlers quietly staring at their phones and tablets while at restaurants and stores. While I have empathy for exhausted parents desperate for a moment of quiet, if this type of screen use is the rule rather than the exception for a child, there is risk for missed opportunities for the development of self-regulation skills.

Additionally, I have seen very young children present to my clinic with poor posture and neck pain secondary to chronic smartphone use, and young children who are getting minimal exercise or outdoor time due to excessive screen use, leading to concerns around fine and gross motor skills as well.

While allowing a child to stay occupied with or be soothed by a highly interesting digital experience can create a more calm environment for all, if habitual, this use can come at a cost regarding opportunities for the growth of executive functioning skills, general coping skills, general situational awareness, and experiential learning. Reliance on screens to decrease uncomfortable experiences decreases the opportunity for building distress tolerance, patience, and coping skills.

Of course there are times of extreme distress where a lollipop or bit of screen time might be reasonable to help keep a child safe or further avoid emotional trauma, but in general, other methods of soothing can very often be utilized, and in the long run would serve to increase the child’s general adaptive functioning.
 

A Teachable Moment

When clinicians encounter screens being used by parents to entertain their kids in clinic, it provides a valuable teaching moment around the risks of using screens to keep kids regulated and occupied during life’s less interesting or more anxiety provoking experiences. Having a meaningful conversation about the use of electronic devices with caregivers by clinicians in the exam room can be a delicate dance between providing supportive education while avoiding judgmental tones or verbiage. Normalizing and sympathizing with the difficulty of managing challenging behaviors from children in public spaces can help parents feel less desperate to keep their child quiet at all costs, and thus allow for greater development of coping skills.

Some parents may benefit from learning simple ideas for keeping a child regulated and occupied during times of waiting such as silly songs and dances, verbal games like “I spy,” and clapping routines. For a child with additional sensory or developmental needs, a referral to an occupational therapist to work on emotional regulation by way of specific sensory tools can be helpful. Parent-Child Interaction Therapy for kids ages 2 to 7 can also help build some relational activities and skills that can be utilized during trying situations to help keep a child settled and occupied.

If a child has qualified for Developmental Disability Services (DDS), medical providers can also write “prescriptions’ for sensory calming items which are often covered financially by DDS, such as chewies, weighted vests, stuffed animals, and fidgets. While vilification of all screen time for children is not necessary or helpful, supporting parents as they navigate and implement appropriate boundaries is important for optimizing child development. Encouraging parents to schedule allowed screen time at home in a very predictable and controlled manner is one method to help limit excessive use, as well as it’s utilization as an emotional regulation tool.

For public outings with children with special needs, and in particular in situations where meltdowns are likely to occur, some families find it helpful to dress their children in clothing or accessories that increase community awareness about their child’s condition (such as an autism awareness t-shirt). This effort can also help deflect unhelpful attention or advice from the public. Some parents choose to carry small cards explaining the child’s developmental differences, which can then be easily handed to unsupportive strangers in community settings during trying moments.

Clinicians can work to utilize even quick visits with families as an opportunity to review the American Academy of Pediatrics screen time recommendations with families, and also direct them to the Family Media Plan creation resources. Parenting in the modern era presents many challenges regarding choices around the use of electronic devices with children, and using the exam room experience as a teaching opportunity may be a helpful way to decrease utilization of screens as emotional regulation tools for children, while also providing general education around healthy use of screens.

Reliance on screens to decrease uncomfortable experiences decreases the opportunity for building distress tolerance, patience, and coping skills.

Of course there are times of extreme distress where a lollipop or bit of screen time might be reasonable to help keep a child safe or further avoid emotional trauma, but in general, other methods of soothing can very often be utilized, and in the long run would serve to increase the child’s general adaptive functioning.
 

A Teachable Moment

When clinicians encounter screens being used by parents to entertain their kids in clinic, it provides a valuable teaching moment around the risks of using screens to keep kids regulated and occupied during life’s less interesting or more anxiety provoking experiences. Having a meaningful conversation about the use of electronic devices with caregivers by clinicians in the exam room can be a delicate dance between providing supportive education while avoiding judgmental tones or verbiage. Normalizing and sympathizing with the difficulty of managing challenging behaviors from children in public spaces can help parents feel less desperate to keep their child quiet at all costs, and thus allow for greater development of coping skills.

Some parents may benefit from learning simple ideas for keeping a child regulated and occupied during times of waiting such as silly songs and dances, verbal games like “I spy,” and clapping routines. For a child with additional sensory or developmental needs, a referral to an occupational therapist to work on emotional regulation by way of specific sensory tools can be helpful. Parent-Child Interaction Therapy for kids ages 2 to 7 can also help build some relational activities and skills that can be utilized during trying situations to help keep a child settled and occupied.

If a child has qualified for Developmental Disability Services (DDS), medical providers can also write “prescriptions’ for sensory calming items which are often covered financially by DDS, such as chewies, weighted vests, stuffed animals, and fidgets. While vilification of all screen time for children is not necessary or helpful, supporting parents as they navigate and implement appropriate boundaries is important for optimizing child development. Encouraging parents to schedule allowed screen time at home in a very predictable and controlled manner is one method to help limit excessive use, as well as it’s utilization as an emotional regulation tool.

For public outings with children with special needs, and in particular in situations where meltdowns are likely to occur, some families find it helpful to dress their children in clothing or accessories that increase community awareness about their child’s condition (such as an autism awareness t-shirt). This effort can also help deflect unhelpful attention or advice from the public. Some parents choose to carry small cards explaining the child’s developmental differences, which can then be easily handed to unsupportive strangers in community settings during trying moments.

Clinicians can work to utilize even quick visits with families as an opportunity to review the American Academy of Pediatrics screen time recommendations with families, and also direct them to the Family Media Plan creation resources. Parenting in the modern era presents many challenges regarding choices around the use of electronic devices with children, and using the exam room experience as a teaching opportunity may be a helpful way to decrease utilization of screens as emotional regulation tools for children, while also providing general education around healthy use of screens.

A 3-year-old presents to my clinic for evaluation of a possible autism spectrum disorder/difference. He has a history of severe emotional dysregulation, as well as reduced social skills and multiple sensory sensitivities. When I enter the exam room he is watching videos on his mom’s phone, and has some difficulty transitioning to play with toys when I encourage him to do so. He is eventually able to cooperate with my testing, though a bit reluctantly, and scores within the low average range for both language and pre-academic skills. His neurologic exam is within normal limits. He utilizes reasonably well-modulated eye contact paired with some typical use of gestures, and his affect is moderately directed and reactive. He displays typical intonation and prosody of speech, though engages in less spontaneous, imaginative, and reciprocal play than would be expected for his age. His mother reports decreased pretend play at home, minimal interest in toys, and difficulty playing cooperatively with other children.

Upon further history, it becomes apparent that the child spends a majority of his time on electronic devices, and has done so since early toddlerhood. Further dialogue suggests that the family became isolated during the COVID-19 pandemic, and has not yet re-engaged with the community in a meaningful way. The child has had rare opportunity for social interactions with other children, and minimal access to outdoor play. His most severe meltdowns generally involve transitions away from screens, and his overwhelmed parents often resort to use of additional screens to calm him once he is dysregulated.

At the end of the visit, through shared decision making, we agree that enrolling the child in a high-quality public preschool will help parents make a concerted effort towards a significant reduction in the hours per day in which the child utilizes electronic devices, while also providing him more exposure to peers. We plan for the child to return in 6 months for a re-evaluation around social-emotional skills, given his current limited exposure to peers and limited “unplugged” play-time.
 

Overutilization of Electronic Devices

As clinicians, we can all see how pervasive the use of electronic devices has become in the lives of the families we care for, as well as in our own lives, and how challenging some aspects of modern parenting have become. The developmental impact of early and excessive use of screens in young children is well documented,¹ but as clinicians it can be tricky to help empower parents to find ways to limit screen time. When parents use screens to comfort and amuse their children during a clinic visit, this situation may serve as an excellent opportunity for a meaningful and respectful conversation around skill deficits which can result from overutilization of electronic devices in young children.

One scenario I often encounter during my patient evaluations as a developmental and behavioral pediatrician is children begging their parents for use of their phone throughout their visits with me. Not infrequently, a child is already on a screen when I enter the exam room, even when there has been a minimal wait time, which often leads to some resistance on behalf of the child as I explain to the family that a significant portion of the visit involves my interactions with the child, testing the child, and observing their child at play. I always provide ample amounts of age-appropriate art supplies, puzzles, fidgets, building toys, and imaginative play items to children during their 30 to 90 minute evaluations, but these are often not appealing to children when they have been very recently engaged with an electronic device. At times I also need to ask caretakers themselves to please disengage from their own electronic devices during the visit so that I can involve them in a detailed discussion about their child.

One challenge with the practice of allowing children access to entertainment on their parent’s smartphones in particular, lies in the fact that these devices are almost always present, meaning there is no natural boundary to inhibit access, in contrast to a television set or stationary computer parked in the family living room. Not dissimilar to candy visible in a parent’s purse, a cell phone becomes a constant temptation for children accustomed to utilizing them at home and public venues, and the incessant begging can wear down already stressed parents.

Children can become conditioned to utilize the distraction of screens to avoid feelings of discomfort or stress, and so can be very persistent and emotional when asking for the use of screens in public settings. Out in the community, I very frequently see young children and toddlers quietly staring at their phones and tablets while at restaurants and stores. While I have empathy for exhausted parents desperate for a moment of quiet, if this type of screen use is the rule rather than the exception for a child, there is risk for missed opportunities for the development of self-regulation skills.

Additionally, I have seen very young children present to my clinic with poor posture and neck pain secondary to chronic smartphone use, and young children who are getting minimal exercise or outdoor time due to excessive screen use, leading to concerns around fine and gross motor skills as well.

Glucagon-like peptide 1 receptor agonists (GLP-1 RAs) given to adolescents with obesity was associated with a one-third decreased risk for suicidal ideation and suicide attempts compared with lifestyle intervention alone, a large international retrospective study found.

A study published in JAMA Pediatrics suggested that GLP-1 RAs such as semaglutide, liraglutide, and tirzepatide, which are widely used to treat type 2 diabetes (T2D), have a favorable psychiatric safety profile and open up potential avenues for prospective studies of psychiatric outcomes in adolescents with obesity.

Investigators Liya Kerem, MD, MSc, and Joshua Stokar, MD, of Hadassah University Medical Center in Jerusalem, Israel, reported that the reduced risk in GLP-1 RA recipients was maintained up to 3 years follow-up compared with propensity score–matched controls treated with behavioral interventions alone.

“These findings support the notion that childhood obesity does not result from lack of willpower and shed light on underlying mechanisms that can be targeted by pharmacotherapy.” Kerem and Stokar wrote.

Other research has suggested these agents have neurobiologic effects unrelated to weight loss that positively affect mood and mental health.
 

Study Details

The analysis included data from December 2019 to June 2024, drawn from 120 international healthcare organizations, mainly in the United States. A total of 4052 racially and ethnically diverse adolescents with obesity (aged 12-18 years [mean age, about 15.5 years]) being treated with an anti-obesity intervention were identified for the GLP-1 RA cohort and 50,112 for the control cohort. The arms were balanced for baseline demographic characteristics, psychiatric medications and comorbidities, and diagnoses associated with socioeconomic status and healthcare access.

Propensity score matching (PSM) resulted in 3456 participants in each of two balanced cohorts.

Before PSM, intervention patients were older (mean age, 15.5 vs 14.7 years), were more likely to be female (59% vs 49%), and had a higher body mass index (41.9 vs 33.8). They also had a higher prevalence of diabetes (40% vs 4%) and treatment with antidiabetic medications.

GLP-1 RA recipients also had a history of psychiatric diagnoses (17% vs 9% for mood disorders) and psychiatric medications (18% vs 7% for antidepressants). Previous use of non–GLP-1 RA anti-obesity medications was uncommon in the cohort overall, although more common in the GLP-1 RA cohort (2.5% vs 0.2% for phentermine).

Prescription of GLP-1 RA was associated with a 33% reduced risk for suicidal ideation or attempts over 12 months of follow-up: 1.45% vs 2.26% (hazard ratio [HR], 0.67; 95% CI, 0.47-0.95; P = .02). It was also associated with a higher rate of gastrointestinal symptoms: 6.9% vs 5.4% (HR, 1.41; 95% CI, 1.12-1.78; P = .003). There was no difference in rates of upper respiratory tract infections (URTIs), although some research suggests these agents reduce URTIs.
 

Mechanisms

The etiology of childhood obesity is complex and multifactorial, the authors wrote, and genetic predisposition to adiposity, an obesogenic environment, and a sedentary lifestyle synergistically contribute to its development. Variants in genes active in the hypothalamic appetite-regulation neurocircuitry appear to be associated with the development of childhood and adolescent obesity.

The authors noted that adolescence carries an increased risk for psychiatric disorders and suicidal ideation. “The amelioration of obesity could indirectly improve these psychiatric comorbidities,” they wrote. In addition, preclinical studies suggested that GLP-1 RA may improve depression-related neuropathology, including neuroinflammation and neurotransmitter imbalance, and may promote neurogenesis.

A recent meta-analysis found that adults with T2D treated with GLP-1 RA showed significant reduction in depression scale scores compared with those treated with non-GLP-1 RA antidiabetic medications.

Commenting on the study but not involved in it, psychiatrist Robert H. Dicker, MD, associate director of child and adolescent psychiatry at Northwell Zucker Hillside Hospital in Glen Oaks, New York, cautioned that these are preliminary data limited by a retrospective review, not a prospective double-blind, placebo-controlled study.

“The mechanism is unknown — is it a direct effect on weight loss with an improvement of quality of life, more positive feedback by the community, enhanced ability to exercise, and a decrease in depressive symptoms?” he asked.

Dicker suggested an alternative hypothesis: Does the GLP-1 RA have a direct effect on neurotransmitters and inflammation and, thus, an impact on mood, emotional regulation, impulse control, and suicide?

“To further answer these questions, prospective studies must be conducted. It is far too early to conclude that these medications are effective in treating mood disorders in our youth,” Dicker said. “But it is promising that these treatments do not appear to increase suicidal ideas and behavior.”

Adding another outsider’s perspective on the study, Suzanne E. Cuda, MD, FOMA, FAAP, a pediatrician who treats childhood obesity in San Antonio, said that while there was no risk for increased psychiatric disease and a suggestion that GLP-1 RAs may reduce suicidal ideation or attempts, “I don’t think this translates to a treatment for depression in adolescents. Nor does this study indicate there could be a decrease in depression due specifically to the use of GLP1Rs. If the results in this study are replicated, however, it would be reassuring to know that adolescents would not be at risk for an increase in suicidal ideation or attempts.”

This study had no external funding. Kerem reported receiving personal fees from Novo Nordisk for lectures on childhood obesity outside of the submitted work. No other disclosures were reported. Dicker and Cuda had no competing interests relevant to their comments.

Primary care physicians (PCPs) play a key role in treating young patients as they progress through the “atopic march” from atopic dermatitis through food allergy, asthma, and allergic rhinitis. They can also help prevent the process from starting.

“The PCP is usually the first clinician a family with concerns about atopic conditions sees, unless they first visit urgent care or an emergency department after an allergic reaction to food. Either way, families rely on their PCP for ongoing guidance,” said Terri F. Brown-Whitehorn, MD, attending physician in the Division of Allergy and Immunology at the Center for Pediatric Eosinophilic Disorders and the Integrative Health Program at Children’s Hospital of Philadelphia.

“The most important thing PCPs can do is know that the atopic march exists, how it progresses over time, and what signs and symptoms to look for,” she told this news organization.
 

The Atopic March

The atopic march describes the progression of allergic diseases in a child over time, with atopic dermatitis and food allergy in infancy tending to be followed by allergic rhinitis and asthma into later childhood and adulthood.

Although the pathophysiology of the inflammation that precedes atopic dermatitis is unclear, two main hypotheses have been proposed. The first suggests a primary immune dysfunction leads to immunoglobulin E (IgE) sensitization, allergic inflammation, and a secondary disturbance of the epithelial barrier; the second starts with a primary defect in the epithelial barrier that leads to secondary immunologic dysregulation and results in inflammation.

Genetics, infection, hygiene, extreme climate, food allergens, probiotics, aeroallergens, and tobacco smoke are thought to play roles in atopic dermatitis. An estimated 10%-12% of children and 1% of adults in the United States have been reported to have the condition, and the prevalence appears to be increasing. An estimated 85% of cases occur during the first year of life and 95% before the age of 5 years.

“Atopy often, though not always, runs in families, so PCPs should inquire about the history of atopic dermatitis, IgE-mediated food allergies, allergic rhinitis, and asthma in the patient’s siblings, parents, and grandparents,” Brown-Whitehorn said.
 

Key Educators

PCPs treat the full gamut of atopic conditions and are key educators on ways families can help mitigate their children’s atopic march or stop it before it begins, said Gerald Bell Lee, MD, an allergist and immunologist at Children’s Healthcare of Atlanta and an associate professor in the Division of Allergy and Immunology at Emory University School of Medicine, Atlanta.

“Most parents who bring their infants with eczema to the PCP assume their child ate something that caused their rash. But the relationship between atopic dermatitis, a type of eczema, and food allergy is more complicated,” he added.

Lee said PCPs should explain to their patients what atopic dermatitis is, how it starts and progresses, and how families can help prevent the condition by, for example, introducing allergenic foods to infants at around 4-6 months of age.
 

Atopic Dermatitis

PCPs should inform parents and other caregivers to wash their hands before moisturizing their child, take care not to contaminate the moisturizer, and bathe their child only when the child is dirty.

“Soap removes protective natural skin oils and increases moisture loss, and exposure to soap and bathing is a main contributor to eczema,” said Lee. “Dry skin loses its protective barrier, allowing outside agents to penetrate and be identified by the immune system.”

“According to one hypothesis, parents may eat food, not wash their hands afterwards, then moisturize their baby. This unhygienic practice spreads food proteins from the adult’s meal, and possibly from contaminants present in the moisturizer, all over the baby’s body,” he added.

Lee said he and his colleagues discourage overbathing babies to minimize the risk for skin injury that begins the atopic march: “New parents are inundated with infant skincare messaging and products. But we need to weigh societal pressures against practicality and ask, ‘Is the child’s skin actually dirty?’ ”

Atopic dermatitis tends to appear on the extensor surfaces, face, and scalp in infants and around arm and leg creases in toddlers and older children. Severe forms of the condition can be more widely distributed on the body, said Aarti P. Pandya, MD, medical director of the Food Allergy Center at Children’s Mercy Kansas City and clinical assistant professor of pediatrics at the University of Missouri-Kansas City School of Medicine, Kansas City, Missouri.
 

Avoid Triggers, Minimize Flares

Triggers of eczema are varied and common. To help minimize flares, PCPs can encourage caregivers to avoid products with fragrances or dyes, minimize the use of soaps, and completely rinse laundry detergent from clothing and household items. “Advise them to keep fingernails short and control dander, pollen, mold, household chemicals, and tobacco smoke, as well as the child’s stress and anxiety, which can also be a trigger,” Lee said.

“Skin infections from organisms such as staph, herpes, or coxsackie can also exacerbate symptoms,” Brown-Whitehorn added. “PCPs can educate caregivers to avoid all known triggers and give them an ‘action plan’ to carry out when skin flares.”
 

Food Allergies

Parents may be unaware food allergens can travel far beyond the plate, Lee said. Researchers vacuuming household bedding, carpets, furniture, and other surfaces have detected unnoticeably tiny quantities of allergenic food proteins in ordinary house dust. Touching this dust appears to provide the main exposure to those allergens.

“According to the dual exposure to allergen hypothesis, an infant’s tolerance to antigens occurs through high-dose exposure by mouth, and allergic sensitization occurs through low-dose exposure through the skin,” he said. “As young as four to six months of age, even before eating solid food, a child develops eczema, has a leaky skin barrier, comes in contact with food, and develops a food allergy.”

IgE-mediated food allergies can begin at any age. “Symptoms occur when a food is ingested and the patient develops symptoms including but not limited to urticaria, angioedema, pruritus, flushing, vomiting, diarrhea, coughing, wheezing, difficulty breathing, presyncope, or syncope,” Pandya noted.

In the case of eosinophilic esophagitis, which may also be part of the atopic march, infants and toddlers often have challenging-to-treat symptoms of reflux, while school-age children have reflux and abdominal pain, and adolescents and adults may experience difficulty swallowing and impactions of food or pills, Brown-Whitehorn said.

To differentiate between food allergy and contact dermatitis, Lee suggested providers ask, “ ’Is the rash hives? If yes, is the rash generalized or in a limited area?’ Then consider the statistical probabilities. Skin problems after milk, egg, wheat, soy, peanut, tree nut, fish, shellfish, or sesame are likely due to IgE-mediated food allergy, but after ketchup or strawberry are probably from skin contact.”
 

Allergic Rhinitis and Asthma

“For asthma, ask about frequency of night cough and symptoms with exercise, laughing, or crying. For allergic rhinitis, look for runny nose, itchy eyes, or sneezing,” Brown-Whitehorn said.

Testing and Monitoring

Assessing the extent of eczema with the Eczema Area and Severity Index or the SCORing Atopic Dermatitis index takes time but may be necessary to obtain insurance coverage for treatments such as biologics.

Avoid ordering IgE food panels, which can result in false positives that can lead to loss of tolerance and nutritional deficiencies; psychological harm from bullying, anxiety, and decreased quality of life; and higher food and healthcare costs, Pandya said.

Treatments
Caregivers may be wary about treatments, and all the three experts this news organization spoke with stressed the importance of educating caregivers about how treatments work and what to expect from them.

“Early and aggressive atopic dermatitis treatment could prevent sensitization to food or aeroallergens, which could help prevent additional atopic diseases, including those on the atopic march,” Pandya said. “Topical steroids are considered first line at any age. Topical phosphodiesterase inhibitors are approved at 3 months of age and above. Topical calcineurin inhibitors are approved at 2 years of age and above. Wet wrap therapy and bleach baths can be effective. Other options include biologic therapy, allergen immunotherapy, and UV therapy.”

“Epinephrine auto-injectors can counteract food reactions. For allergic rhinitis, non-sedating antihistamines, steroidal nasal sprays, and nasal antihistamines help. Asthma treatments include various inhaled medications,” Brown-Whitehorn added.
 

When to Refer to Specialists

Involving an allergist, dermatologist, pulmonologist, or ear nose throat specialist to the patient’s care team is advisable in more challenging cases.

If a child is younger than 3 months and has moderate to severe atopic dermatitis, an underlying immune defect may be to blame, so an allergy and immunology assessment is warranted, Brown-Whitehorn said. “An allergist can help any child who has recurrent coughing or wheezing avoid the emergency room or hospitalization.”

“In pediatrics, we always try to find the medication, regimen, and avoidance strategies that use the least treatment to provide the best care for each patient,” Brown-Whitehorn added. “Children eat, play, learn, and sleep, and every stage of the atopic march affects each of these activities. As clinicians, we need to be sure that we are helping children make the best of all these activities.”

Primary care physicians (PCPs) play a key role in treating young patients as they progress through the “atopic march” from atopic dermatitis through food allergy, asthma, and allergic rhinitis. They can also help prevent the process from starting.

“The PCP is usually the first clinician a family with concerns about atopic conditions sees, unless they first visit urgent care or an emergency department after an allergic reaction to food. Either way, families rely on their PCP for ongoing guidance,” said Terri F. Brown-Whitehorn, MD, attending physician in the Division of Allergy and Immunology at the Center for Pediatric Eosinophilic Disorders and the Integrative Health Program at Children’s Hospital of Philadelphia.

“The most important thing PCPs can do is know that the atopic march exists, how it progresses over time, and what signs and symptoms to look for,” she told this news organization.
 

The Atopic March

The atopic march describes the progression of allergic diseases in a child over time, with atopic dermatitis and food allergy in infancy tending to be followed by allergic rhinitis and asthma into later childhood and adulthood.

Although the pathophysiology of the inflammation that precedes atopic dermatitis is unclear, two main hypotheses have been proposed. The first suggests a primary immune dysfunction leads to immunoglobulin E (IgE) sensitization, allergic inflammation, and a secondary disturbance of the epithelial barrier; the second starts with a primary defect in the epithelial barrier that leads to secondary immunologic dysregulation and results in inflammation.

Genetics, infection, hygiene, extreme climate, food allergens, probiotics, aeroallergens, and tobacco smoke are thought to play roles in atopic dermatitis. An estimated 10%-12% of children and 1% of adults in the United States have been reported to have the condition, and the prevalence appears to be increasing. An estimated 85% of cases occur during the first year of life and 95% before the age of 5 years.

“Atopy often, though not always, runs in families, so PCPs should inquire about the history of atopic dermatitis, IgE-mediated food allergies, allergic rhinitis, and asthma in the patient’s siblings, parents, and grandparents,” Brown-Whitehorn said.
 

Key Educators

PCPs treat the full gamut of atopic conditions and are key educators on ways families can help mitigate their children’s atopic march or stop it before it begins, said Gerald Bell Lee, MD, an allergist and immunologist at Children’s Healthcare of Atlanta and an associate professor in the Division of Allergy and Immunology at Emory University School of Medicine, Atlanta.

“Most parents who bring their infants with eczema to the PCP assume their child ate something that caused their rash. But the relationship between atopic dermatitis, a type of eczema, and food allergy is more complicated,” he added.

Lee said PCPs should explain to their patients what atopic dermatitis is, how it starts and progresses, and how families can help prevent the condition by, for example, introducing allergenic foods to infants at around 4-6 months of age.
 

Atopic Dermatitis

PCPs should inform parents and other caregivers to wash their hands before moisturizing their child, take care not to contaminate the moisturizer, and bathe their child only when the child is dirty.

“Soap removes protective natural skin oils and increases moisture loss, and exposure to soap and bathing is a main contributor to eczema,” said Lee. “Dry skin loses its protective barrier, allowing outside agents to penetrate and be identified by the immune system.”

“According to one hypothesis, parents may eat food, not wash their hands afterwards, then moisturize their baby. This unhygienic practice spreads food proteins from the adult’s meal, and possibly from contaminants present in the moisturizer, all over the baby’s body,” he added.

Lee said he and his colleagues discourage overbathing babies to minimize the risk for skin injury that begins the atopic march: “New parents are inundated with infant skincare messaging and products. But we need to weigh societal pressures against practicality and ask, ‘Is the child’s skin actually dirty?’ ”

Atopic dermatitis tends to appear on the extensor surfaces, face, and scalp in infants and around arm and leg creases in toddlers and older children. Severe forms of the condition can be more widely distributed on the body, said Aarti P. Pandya, MD, medical director of the Food Allergy Center at Children’s Mercy Kansas City and clinical assistant professor of pediatrics at the University of Missouri-Kansas City School of Medicine, Kansas City, Missouri.
 

Avoid Triggers, Minimize Flares

Triggers of eczema are varied and common. To help minimize flares, PCPs can encourage caregivers to avoid products with fragrances or dyes, minimize the use of soaps, and completely rinse laundry detergent from clothing and household items. “Advise them to keep fingernails short and control dander, pollen, mold, household chemicals, and tobacco smoke, as well as the child’s stress and anxiety, which can also be a trigger,” Lee said.

“Skin infections from organisms such as staph, herpes, or coxsackie can also exacerbate symptoms,” Brown-Whitehorn added. “PCPs can educate caregivers to avoid all known triggers and give them an ‘action plan’ to carry out when skin flares.”
 

Food Allergies

Parents may be unaware food allergens can travel far beyond the plate, Lee said. Researchers vacuuming household bedding, carpets, furniture, and other surfaces have detected unnoticeably tiny quantities of allergenic food proteins in ordinary house dust. Touching this dust appears to provide the main exposure to those allergens.

“According to the dual exposure to allergen hypothesis, an infant’s tolerance to antigens occurs through high-dose exposure by mouth, and allergic sensitization occurs through low-dose exposure through the skin,” he said. “As young as four to six months of age, even before eating solid food, a child develops eczema, has a leaky skin barrier, comes in contact with food, and develops a food allergy.”

In Canada, switching to a one-dose, gender-neutral vaccination program for human papillomavirus (HPV) could use vaccine doses more efficiently and prevent a similar number of cervical cancer cases, compared with a two-dose program, according to a new modeling analysis.

If vaccine protection remains high during the ages of peak sexual activity, all one-dose vaccination options are projected to be “substantially more efficient” than two-dose programs, even in the most pessimistic scenarios, the study authors wrote.

In addition, the scenarios projected the elimination of cervical cancer in Canada between 2032 and 2040. HPV can also lead to oral, throat, and penile cancers, and most are preventable through vaccination.

“The COVID-19 pandemic has impacted HPV vaccination in Canada, particularly among vulnerable population subgroups,” said study author Chantal Sauvageau, MD, a consultant in infectious diseases at the National Institute of Public Health of Quebec and associate professor of social and preventive medicine at the University of Laval, Quebec City, Canada.

Switching to one-dose vaccination would offer potential economic savings and programmatic flexibility, she added. The change also could enable investments aimed at increasing vaccination rates in regions where coverage is suboptimal, as well as in subgroups with a high HPV burden. Such initiatives could mitigate the pandemic’s impact on health programs and reduce inequalities.

The study was published online in CMAJ.
 

Vaccination Program Changes

Globally, countries have been investigating whether to shift from a two-dose to a one-dose HPV vaccine strategy since the World Health Organization’s Strategic Advisory Group of Experts on Immunization issued a single-dose recommendation in 2022.

In July, Canada’s National Advisory Committee on Immunization (NACI) updated its guidelines to recommend the single-dose approach for ages 9-20 years. The change aligns Canada with 35 other countries, including Australia and the United Kingdom. Canada›s vaccine advisory group still recommends two doses for ages 21-26 years and three doses for patients who are immunocompromised or have HIV.

To help inform new NACI policies, Sauvageau and colleagues modeled several one-dose and two-dose strategies using HPV-ADVISE, an individual-based transmission-dynamic model of HPV infections and diseases. They looked at vaccination programs in Quebec, which has a high HPV vaccine coverage rate of around 85%, and Ontario, which has lower coverage of around 65%.

For one-dose programs, the researchers analyzed noninferior (98% efficacy) and pessimistic (90% efficacy) scenarios and different average vaccine duration periods, including lifelong, 30-year, and 25-year coverage. They compared the scenarios with a two-dose program with 98% efficacy and lifelong duration, estimating the relative reduction in HPV-16 infection and cervical cancer incidence and the number of doses needed to prevent one cervical cancer case.

Overall, the model projected that gender-neutral HPV vaccine programs with either two doses or a noninferior one dose would nearly eliminate HPV-16 infection by 2040-2045 in Quebec and reduce infection by more than 90% in Ontario. Under a one-dose strategy with 90% vaccine efficacy, rebounds in HPV-16 infection would start more than 25-30 years after a switch to a lower-dose strategy, thus providing time for officials to detect any signs of waning efficacy and change policies, if needed, the authors wrote.

In addition, the model projected that a noninferior one-dose, gender-neutral HPV vaccination program would avert a similar number of cervical cancer cases, compared with a two-dose program. The reduction would be about 60% in Quebec and 55% in Ontario, compared with no vaccination. Under the most pessimistic scenario with 25-year vaccine duration, a one-dose program would be slightly less effective in averting cancer: about 3% lower than a two-dose program over 100 years.

All one-dose scenarios were projected to lead to the elimination of cervical cancer in 8-16 years — at fewer than four cervical cancer cases per 100,000 female-years.

One-dose programs would also lead to more efficient use of vaccine doses, with about 800-1000 doses needed to prevent one cervical cancer case in a one-dose program and more than 10,000 incremental doses needed to prevent one additional cervical cancer case in a two-dose program.
 

What Next?

In Canada, the HPV vaccine is authorized for patients aged 9-45 years. Current immunization coverage among adolescents and young adults varies across provinces and falls below the national target of 90%. In its July 2024 update, NACI estimated that 76% of 14-year-olds of both genders received at least one vaccine dose and that 67% received two doses in 2023. Vaccine uptake was slightly higher among girls than boys.

To boost the coverage rate, shifting to a one-dose schedule could appeal to young people, as well as maintain vaccination efficacy.

“When you look at the studies that have been published worldwide, the effectiveness of one dose of the HPV vaccine is actually quite high,” said Caroline Quach-Thanh, MD, professor of microbiology, infectious diseases, immunology, and pediatrics at the University of Montreal, Quebec, Canada.

Quach-Thanh, who wasn’t involved with this study, previously served as NACI chair and now serves as chair of the Quebec Immunization Committee.

“In terms of prevention of HPV infections that may lead to cancer, whether you give one dose or two doses basically gives you the same amount of protection,” she said.

However, not all physicians agree about the switch in vaccination approaches. In early October, the Federation of Medical Women of Canada released a report with 12 recommendations to increase HPV vaccination rates, including a call for healthcare providers to continue with multidose immunization schedules for now.

“Vaccination is the most powerful action we can take in preventing HPV-related cancers. Canada is falling behind, but we can get back on track if we act quickly,” said Vivien Brown, MD, chair of the group’s HPV Immunization Task Force, chair and cofounder of HPV Prevention Week in Canada, and a past president of the federation.

After the NACI update in July, the task force evaluated the risks and benefits of a single-dose vaccine regimen, she said. They concluded that a multidose schedule should continue at this time because of its proven effectiveness.

“Until more research on the efficacy of a single-dose schedule becomes available, healthcare providers and public health agencies should continue to offer patients a multidose schedule,” said Brown. “This is the only way to ensure individuals are protected against HPV infection and cancer over the long term.”

The study was supported by the Public Health Agency of Canada, the Canadian Institutes of Health Research, the Bill & Melinda Gates Foundation, and Canadian Immunization Research Network. Sauvageau, Quach-Thanh, and Brown declared no relevant financial disclosures.

In early October, the Federation of Medical Women of Canada released a report with 12 recommendations to increase HPV vaccination rates, including a call for healthcare providers to continue with multidose immunization schedules for now.

“Vaccination is the most powerful action we can take in preventing HPV-related cancers. Canada is falling behind, but we can get back on track if we act quickly,” said Vivien Brown, MD, chair of the group’s HPV Immunization Task Force, chair and cofounder of HPV Prevention Week in Canada, and a past president of the federation.

After the NACI update in July, the task force evaluated the risks and benefits of a single-dose vaccine regimen, she said. They concluded that a multidose schedule should continue at this time because of its proven effectiveness.

“Until more research on the efficacy of a single-dose schedule becomes available, healthcare providers and public health agencies should continue to offer patients a multidose schedule,” said Brown. “This is the only way to ensure individuals are protected against HPV infection and cancer over the long term.”

The study was supported by the Public Health Agency of Canada, the Canadian Institutes of Health Research, the Bill & Melinda Gates Foundation, and Canadian Immunization Research Network. Sauvageau, Quach-Thanh, and Brown declared no relevant financial disclosures.

In Canada, switching to a one-dose, gender-neutral vaccination program for human papillomavirus (HPV) could use vaccine doses more efficiently and prevent a similar number of cervical cancer cases, compared with a two-dose program, according to a new modeling analysis.

If vaccine protection remains high during the ages of peak sexual activity, all one-dose vaccination options are projected to be “substantially more efficient” than two-dose programs, even in the most pessimistic scenarios, the study authors wrote.

In addition, the scenarios projected the elimination of cervical cancer in Canada between 2032 and 2040. HPV can also lead to oral, throat, and penile cancers, and most are preventable through vaccination.

“The COVID-19 pandemic has impacted HPV vaccination in Canada, particularly among vulnerable population subgroups,” said study author Chantal Sauvageau, MD, a consultant in infectious diseases at the National Institute of Public Health of Quebec and associate professor of social and preventive medicine at the University of Laval, Quebec City, Canada.

Switching to one-dose vaccination would offer potential economic savings and programmatic flexibility, she added. The change also could enable investments aimed at increasing vaccination rates in regions where coverage is suboptimal, as well as in subgroups with a high HPV burden. Such initiatives could mitigate the pandemic’s impact on health programs and reduce inequalities.

Vaccination Program Changes

Globally, countries have been investigating whether to shift from a two-dose to a one-dose HPV vaccine strategy since the World Health Organization’s Strategic Advisory Group of Experts on Immunization issued a single-dose recommendation in 2022.

In July, Canada’s National Advisory Committee on Immunization (NACI) updated its guidelines to recommend the single-dose approach for ages 9-20 years. The change aligns Canada with 35 other countries, including Australia and the United Kingdom. Canada›s vaccine advisory group still recommends two doses for ages 21-26 years and three doses for patients who are immunocompromised or have HIV.

To help inform new NACI policies, Sauvageau and colleagues modeled several one-dose and two-dose strategies using HPV-ADVISE, an individual-based transmission-dynamic model of HPV infections and diseases. They looked at vaccination programs in Quebec, which has a high HPV vaccine coverage rate of around 85%, and Ontario, which has lower coverage of around 65%.

For one-dose programs, the researchers analyzed noninferior (98% efficacy) and pessimistic (90% efficacy) scenarios and different average vaccine duration periods, including lifelong, 30-year, and 25-year coverage. They compared the scenarios with a two-dose program with 98% efficacy and lifelong duration, estimating the relative reduction in HPV-16 infection and cervical cancer incidence and the number of doses needed to prevent one cervical cancer case.

Overall, the model projected that gender-neutral HPV vaccine programs with either two doses or a noninferior one dose would nearly eliminate HPV-16 infection by 2040-2045 in Quebec and reduce infection by more than 90% in Ontario. Under a one-dose strategy with 90% vaccine efficacy, rebounds in HPV-16 infection would start more than 25-30 years after a switch to a lower-dose strategy, thus providing time for officials to detect any signs of waning efficacy and change policies, if needed, the authors wrote.

In addition, the model projected that a noninferior one-dose, gender-neutral HPV vaccination program would avert a similar number of cervical cancer cases, compared with a two-dose program. The reduction would be about 60% in Quebec and 55% in Ontario, compared with no vaccination. Under the most pessimistic scenario with 25-year vaccine duration, a one-dose program would be slightly less effective in averting cancer: about 3% lower than a two-dose program over 100 years.

All one-dose scenarios were projected to lead to the elimination of cervical cancer in 8-16 years — at fewer than four cervical cancer cases per 100,000 female-years.

One-dose programs would also lead to more efficient use of vaccine doses, with about 800-1000 doses needed to prevent one cervical cancer case in a one-dose program and more than 10,000 incremental doses needed to prevent one additional cervical cancer case in a two-dose program.
 

What Next?

In Canada, the HPV vaccine is authorized for patients aged 9-45 years. Current immunization coverage among adolescents and young adults varies across provinces and falls below the national target of 90%. In its July 2024 update, NACI estimated that 76% of 14-year-olds of both genders received at least one vaccine dose and that 67% received two doses in 2023. Vaccine uptake was slightly higher among girls than boys.

To boost the coverage rate, shifting to a one-dose schedule could appeal to young people, as well as maintain vaccination efficacy.

“When you look at the studies that have been published worldwide, the effectiveness of one dose of the HPV vaccine is actually quite high,” said Caroline Quach-Thanh, MD, professor of microbiology, infectious diseases, immunology, and pediatrics at the University of Montreal, Quebec, Canada.

Quach-Thanh, who wasn’t involved with this study, previously served as NACI chair and now serves as chair of the Quebec Immunization Committee.

“In terms of prevention of HPV infections that may lead to cancer, whether you give one dose or two doses basically gives you the same amount of protection,” she said.

However, not all physicians agree about the switch in vaccination approaches. In early October, the Federation of Medical Women of Canada released a report with 12 recommendations to increase HPV vaccination rates, including a call for healthcare providers to continue with multidose immunization schedules for now.
