Pediatrics

Has anyone else noticed how slow it has been on your pediatric floors? Well, you are not alone.

The COVID pandemic has had a significant impact on health care volumes, with pediatric volumes decreasing across the nation. A Children’s Hospital Association CEO survey, currently unpublished, noted a 10%-20% decline in inpatient admissions and a 30%-50% decline in pediatric ED visits this past year. Even our usual respiratory surge has been disrupted. The rate of influenza tracked by the CDC is around 1%, compared with the usual seasonal flu baseline national rate of 2.6%. These COVID-related declines have occurred amidst the backdrop of already-decreasing inpatient admissions because of the great work of the pediatric hospital medicine (PHM) community in reducing unnecessary admissions and lengths of stay.

For many hospitals, several factors related to the pandemic have raised significant financial concerns. According to Becker Hospital Review, as of August 2020 over 500 hospitals had furloughed workers. While 26 of those hospitals had brought back workers by December 2020, many did not. Similar financial concerns were noted in a Kaufmann Hall report from January 2021, which showed a median drop of 55% in operating margins. The CARES Act helped reduce some of the detrimental impact on operating margins, but it did not diminish the added burden of personal protective equipment expenses, longer length of stay for COVID patients, and a reimbursement shift to more government payors and uninsured caused by pandemic-forced job losses.

COVID’s impact specific to pediatric hospital medicine has been substantial. A recent unpublished survey by the PHM Economics Research Collaborative (PERC) demonstrated how COVID has affected pediatric hospital medicine programs. Forty-five unique PHM programs from over 21 states responded, with 98% reporting a decrease in pediatric inpatient admissions as well as ED visits. About 11% reported temporary unit closures, while 51% of all programs reported staffing restrictions ranging from hiring freezes to downsizing the number of hospitalists in the group. Salaries decreased in 26% of reporting programs, and 20%-56% described reduced benefits, ranging from less CME/vacation time and stipends to retirement benefits. The three most frequent benefit losses included annual salary increases, educational stipends, and bonuses.

Community hospitals felt the palpable, financial strain of decreasing pediatric admissions well before the pandemic. Hospitals like MedStar Franklin Square Hospital in Baltimore and Harrington Hospital in Southbridge, Mass., had decided to close their pediatrics units before COVID hit. In a 2014 unpublished survey of 349 community PHM (CPHM) programs, 57% of respondents felt that finances and justification for a pediatric program were primary concerns.

Responding to financial stressors is not a novel challenge for CPHM programs. To keep these vital pediatric programs in place despite lower inpatient volumes, those of us in CPHM have learned many lessons over the years on how to adapt. Such adaptations have included diversification in procedures and multifloor coverage in the hospital. Voiding cystourethrogram catheterizations and circumcisions are now more commonly performed by CPHM providers, who may also cover multiple areas of the hospital, including the ED, NICU, and well-newborn nursery. Comanagement of subspecialty or surgical patients is yet another example of such diversification.

Furthermore, the PERC survey showed that some PHM programs temporarily covered pediatric ICUs and step-down units and began doing ED and urgent care coverage as primary providers Most programs reported no change in newborn visits while 16% reported an increase in newborn volume and 14% reported a decrease in newborn volume. My own health system was one of the groups that had an increase in newborn volume. This was caused by community pediatricians who had stopped coming in to see their own newborns. This coverage adjustment has yet to return to baseline and will likely become permanent.

There was a 11% increase from prepandemic baselines (from 9% to 20%) in programs doing telemedicine. Most respondents stated that they will continue to offer telemedicine with an additional 25% of programs considering starting. There was also a slight increase during the pandemic of coverage of mental health units (from 11% to 13%), which may have led 11% of respondents to consider the addition of this service. The survey also noted that about 28% of PHM programs performed circumcisions, frenectomies, and sedation prepandemic, and 14%-18% are considering adding these services.

Overall, the financial stressors are improving, but our need to adapt in PHM is more pressing than ever. The pandemic has given us the push for evolution and some opportunities that did not exist before. One is the use of telemedicine to expand our subspecialty support to community hospitals, as well as to children’s hospitals in areas where subspecialists are in short supply. These telemedicine consults are being reimbursed for the first time, which allows more access to these services.

With the pandemic, many hospitals are moving to single room occupancy models. Construction to add more beds is costly, and unnecessary if we can utilize community hospitals to keep appropriate patients in their home communities. The opportunity to partner with community hospital programs to provide telemedicine support should not be overlooked. This is also an opportunity for academic referral centers to have more open beds for critical care and highly specialized patients.

Another opportunity is to expand scope by changing age limits, as 18% of respondents to the PERC survey reported that they had started to care for adults since the pandemic. The Pediatric Overflow Planning Contingency Response Network (POPCoRN) has been a valuable resource for education on caring for adults, guidance on which patient populations are appropriate, and the resources needed to do this. While caring for older adults, even in their 90s, was a pandemic-related phenomenon, there is an opportunity to see if the age limit we care for should be raised to 21, or even 25, as some CPHM programs had been doing prepandemic.

Along with the expansion of age limits, there are many other areas of opportunity highlighted within the PERC survey. These include expanding coverage within pediatric ICUs, EDs, and urgent care areas, along with coverage of well newborns that were previously covered by community pediatricians. Also, the increase of mental health admissions is another area where PHM programs might expand their services.

While I hope the financial stressors improve, hope is not a plan and therefore we need to think and prepare for what the post-COVID future may look like. Some have predicted a rebound pediatric respiratory surge next year as the masks come off and children return to in-person learning and daycare. This may be true, but we would be foolish not to use lessons from the pandemic as well as the past to consider options in our toolkit to become more financially stable. POPCoRN, as well as the American Academy of Pediatrics’ listserv and subcommittees, have been a source of collaboration and shared knowledge during a time when we have needed to quickly respond to ever-changing information. These networks and information sharing should be leveraged once the dust settles for us to prepare for future challenges.

New innovations may arise as we look at how we address the growing need for mental health services and incorporate new procedures, like point of care ultrasound. As Charles Darwin said: “It is not the strongest of the species that survives nor the most intelligent that survives. It is the one that is most adaptable to change.” It is time for us to evolve.

Cardiovascular and metabolic risk factors are increased among transgender youths, compared with youths who are not transgender. Elevations in lipid levels and body mass index (BMI) also occur in adult transgender patients, new research shows.

“This is the first study of its size in the United States of which we are aware that looks at the odds of youth with a diagnosis of gender dysphoria having medical diagnoses that relate to overall metabolic and cardiovascular health,” first author Anna Valentine, MD, of Children’s Hospital Colorado, Aurora, said in a press statement.

Although previous studies have shown that among transgender adults, BMI is higher and there is an increased risk for cardiovascular events, such as stroke or heart attack, compared with nontransgender people, research on adolescent transgender patients has been lacking.

With a recent survey showing that nearly 2% of adolescents identify as transgender, interest in health outcomes among younger patients is high.

To investigate, Dr. Valentine, and colleagues evaluated data from the PEDSnet pediatric database on 4,177 youths who had received a diagnosis of gender dysphoria. The participants had been enrolled at six sites from 2009 to 2019. The researchers compared these patients in a ratio of 1:4 with 16,664 control persons who had not been diagnosed with gender dysphoria. They reported their findings as a poster at the annual meeting of the Endocrine Society.

For the propensity-score analysis, participants were matched according to year of birth, age at last visit, site, race, ethnicity, insurance status, and duration in the database.

In both the transgender and control groups, about 66% were female at birth, 73% were White, and 9% Hispanic. For both groups, the average age was 16.2 years at the last visit. The average duration in the database was 7 years.
 

Study didn’t distinguish between those receiving and those not receiving gender-affirming hormones

In the retrospective study, among those who identified as transgender, the rates of diagnoses of dyslipidemia (odds ratio, 1.6; P < .0001) and metabolic syndrome (OR, 1.9; P = .0086) were significantly higher, compared with those without gender dysphoria.

Among the transgender male patients (born female) but not transgender female patients (born male), rates of diagnoses of overweight/obesity (OR, 1.7; P < .0001) and polycystic ovary syndrome were higher (OR, 1.9, P = .0006), compared with controls.

Gender-affirming hormone therapy, such as with testosterone or estradiol, is among the suspected culprits for the cardiovascular effects. However, importantly, this study did not differentiate between patients who had received estradiol or testosterone for gender affirmation and those who had not, Dr. Valentine said.

“We don’t know [whether gender-affirming hormone therapy is a cause], as we have not looked at this yet,” she said in an interview. “We are looking at that in our next analyses and will be including that in our future publication.

“We’ll also be looking at the relationship between having overweight/obesity and the other diagnoses that influence cardiovascular health (high blood pressure, liver dysfunction, and abnormal cholesterol), as that could certainly be playing a role as well,” she said.

For many transgender patients, gender-affirming hormone therapy is lifelong. One question that needs to be evaluated concerns whether the dose of such therapy has a role on cardiovascular effects and if so, whether adjustments could be made without compromising the therapeutic effect, Dr. Valentine noted.

“This is an important question, and future research is needed to evaluate whether doses [of gender-affirming hormones] are related to cardiometabolic outcomes,” she said.

Potential confounders in the study include the fact that rates of overweight and obesity are higher among youths with gender dysphoria. This can in itself can increase the risk for other disorders, Dr. Valentine noted.

Furthermore, rates of mental health comorbidities are higher among youths with gender dysphoria. One consequence of this may be that they engage in less physical activity, she said.
 

Hormone therapy, health care disparities, or both could explain risk

In commenting on the study, Joshua D. Safer, MD, executive director of the Center for Transgender Medicine and Surgery, the Mount Sinai Health System, New York, said that although similar cardiovascular effects are known to occur in transgender adults as well, they may or may not be hormone related. Other factors can increase the risk.

“With transgender adults, any differences in lipids or cardiac risk factors relative to cisgender people might be attributable either to hormone therapy or to health care disparities,” he said in an interview.

“The data are mixed. It may be that most differences relate to lack of access to care and to mistreatment by society,” he said. “Even studies that focus on hormones see a worsened situation for trans women versus trans men.”

Other recent research that shows potential cardiovascular effects among adult transgender men includes a study of more than 1,000 transgender men (born female) who received testosterone. That study, which was also presented at the ENDO meeting and was reported by this news organization, found an increased risk for high hematocrit levels, which could lead to a thrombotic event.

However, a study published in Pediatrics, which was also reported by this news organization, that included 611 transgender youths who had taken gender-affirming hormone therapy for more than a year found no increased risk for thrombosis, even in the presence of thrombosis risk factors, including obesity, tobacco use, and family history of thrombosis. However, the senior author of that study pointed out that the duration of follow-up in that study was relatively short, which may have been why they did not find an increased risk for thrombosis.

Dr. Safer noted that transgender youths and adults alike face a host of cultural factors that could play a role in increased cardiovascular risks.

“For adults, the major candidate explanations for worse BMI and cardiac risk factors are societal mistreatment, and for trans women specifically, progestins. For youth, the major candidate explanations are societal mistreatment and lack of access to athletics,” he said.

The authors and Dr. Safer disclosed no relevant financial relationships.

“This is the first study of its size in the United States of which we are aware that looks at the odds of youth with a diagnosis of gender dysphoria having medical diagnoses that relate to overall metabolic and cardiovascular health,” first author Anna Valentine, MD, of Children’s Hospital Colorado, Aurora, said in a press statement.

Although previous studies have shown that among transgender adults, BMI is higher and there is an increased risk for cardiovascular events, such as stroke or heart attack, compared with nontransgender people, research on adolescent transgender patients has been lacking.

With a recent survey showing that nearly 2% of adolescents identify as transgender, interest in health outcomes among younger patients is high.

To investigate, Dr. Valentine, and colleagues evaluated data from the PEDSnet pediatric database on 4,177 youths who had received a diagnosis of gender dysphoria. The participants had been enrolled at six sites from 2009 to 2019. The researchers compared these patients in a ratio of 1:4 with 16,664 control persons who had not been diagnosed with gender dysphoria. They reported their findings as a poster at the annual meeting of the Endocrine Society.

For the propensity-score analysis, participants were matched according to year of birth, age at last visit, site, race, ethnicity, insurance status, and duration in the database.

In both the transgender and control groups, about 66% were female at birth, 73% were White, and 9% Hispanic. For both groups, the average age was 16.2 years at the last visit. The average duration in the database was 7 years.
 

Study didn’t distinguish between those receiving and those not receiving gender-affirming hormones

In the retrospective study, among those who identified as transgender, the rates of diagnoses of dyslipidemia (odds ratio, 1.6; P < .0001) and metabolic syndrome (OR, 1.9; P = .0086) were significantly higher, compared with those without gender dysphoria.

Among the transgender male patients (born female) but not transgender female patients (born male), rates of diagnoses of overweight/obesity (OR, 1.7; P < .0001) and polycystic ovary syndrome were higher (OR, 1.9, P = .0006), compared with controls.

Gender-affirming hormone therapy, such as with testosterone or estradiol, is among the suspected culprits for the cardiovascular effects. However, importantly, this study did not differentiate between patients who had received estradiol or testosterone for gender affirmation and those who had not, Dr. Valentine said.

“We don’t know [whether gender-affirming hormone therapy is a cause], as we have not looked at this yet,” she said in an interview. “We are looking at that in our next analyses and will be including that in our future publication.

“We’ll also be looking at the relationship between having overweight/obesity and the other diagnoses that influence cardiovascular health (high blood pressure, liver dysfunction, and abnormal cholesterol), as that could certainly be playing a role as well,” she said.

For many transgender patients, gender-affirming hormone therapy is lifelong. One question that needs to be evaluated concerns whether the dose of such therapy has a role on cardiovascular effects and if so, whether adjustments could be made without compromising the therapeutic effect, Dr. Valentine noted.

“This is an important question, and future research is needed to evaluate whether doses [of gender-affirming hormones] are related to cardiometabolic outcomes,” she said.

Potential confounders in the study include the fact that rates of overweight and obesity are higher among youths with gender dysphoria. This can in itself can increase the risk for other disorders, Dr. Valentine noted.

Furthermore, rates of mental health comorbidities are higher among youths with gender dysphoria. One consequence of this may be that they engage in less physical activity, she said.
 

Hormone therapy, health care disparities, or both could explain risk

In commenting on the study, Joshua D. Safer, MD, executive director of the Center for Transgender Medicine and Surgery, the Mount Sinai Health System, New York, said that although similar cardiovascular effects are known to occur in transgender adults as well, they may or may not be hormone related. Other factors can increase the risk.

“With transgender adults, any differences in lipids or cardiac risk factors relative to cisgender people might be attributable either to hormone therapy or to health care disparities,” he said in an interview.

“The data are mixed. It may be that most differences relate to lack of access to care and to mistreatment by society,” he said. “Even studies that focus on hormones see a worsened situation for trans women versus trans men.”

Other recent research that shows potential cardiovascular effects among adult transgender men includes a study of more than 1,000 transgender men (born female) who received testosterone. That study, which was also presented at the ENDO meeting and was reported by this news organization, found an increased risk for high hematocrit levels, which could lead to a thrombotic event.

However, a study published in Pediatrics, which was also reported by this news organization, that included 611 transgender youths who had taken gender-affirming hormone therapy for more than a year found no increased risk for thrombosis, even in the presence of thrombosis risk factors, including obesity, tobacco use, and family history of thrombosis. However, the senior author of that study pointed out that the duration of follow-up in that study was relatively short, which may have been why they did not find an increased risk for thrombosis.

Dr. Safer noted that transgender youths and adults alike face a host of cultural factors that could play a role in increased cardiovascular risks.

“For adults, the major candidate explanations for worse BMI and cardiac risk factors are societal mistreatment, and for trans women specifically, progestins. For youth, the major candidate explanations are societal mistreatment and lack of access to athletics,” he said.

The authors and Dr. Safer disclosed no relevant financial relationships.

The Food and Drug Administration has approved the nonstimulant medication viloxazine extended-release capsules (Qelbree, Supernus Pharmaceuticals) for the treatment of attention deficit hyperactivity disorder (ADHD) in children aged 6-17 years, the company has announced.

Viloxazine (formerly SPN-812) is a selective norepinephrine reuptake inhibitor. Capsules may be swallowed whole or opened and the entire contents sprinkled onto applesauce, as needed.

The approval of viloxazine is supported by data from four phase 3 clinical trials involving more than 1,000 pediatric patients aged 6-17 years, the company said.

In one randomized, placebo-controlled phase 3 study that included more than 400 children, viloxazine reduced symptoms of ADHD as soon as 1 week after dosing and was well tolerated.

As reported by this news organization, the study was published last July in Clinical Therapeutics.

In addition to its fast onset of action, the fact that it was effective for both inattentive and hyperactive/impulsive clusters of symptoms is “impressive,” study investigator Andrew Cutler, MD, clinical associate professor of psychiatry, SUNY Upstate Medical University, Syracuse, N.Y., said in an interview.

Also noteworthy was the improvement in measures of quality of life and function, “especially function in the areas of school, home life, family relations, and peer relationships, which can be really disrupted with ADHD,” Dr. Cutler said.

The prescribing label for viloxazine includes a boxed warning regarding the potential for suicidal thoughts and behaviors in some children with ADHD treated with the drug, especially within the first few months of treatment or when the dose is changed. 

In clinical trials, higher rates of suicidal thoughts and behavior were reported in pediatric patients treated with viloxazine than in patients treated with placebo. Patients taking viloxazine should be closely monitored for any new or sudden changes in mood, behavior, thoughts, and feelings.

Viloxazine has shown promise in a phase 3 trial involving adults with ADHD.

The company plans to submit a supplemental new drug application to the FDA for viloxazine in adults later this year.

Patients being treated with infliximab had weakened immune responses to the first dose of the ChAdOx1 nCoV-19 (Oxford/AstraZeneca) and BNT162b2 (Pfizer/BioNTech) vaccines, compared with patients on vedolizumab (Entyvio), although a very significant number of patients from both groups seroconverted after their second dose, according to a new U.K. study of patients with inflammatory bowel disease (IBD).

“Antibody testing and adapted vaccine schedules should be considered to protect these at-risk patients,” Nicholas A. Kennedy, PhD, MBBS, of the University of Exeter (England) and colleagues wrote in a preprint published March 29 on MedRxiv.

Infliximab is an anti–tumor necrosis factor (anti-TNF) monoclonal antibody that’s approved to treat adult and pediatric Crohn’s disease and ulcerative colitis, as well as rheumatoid arthritis, ankylosing spondylitis, psoriatic arthritis, and plaque psoriasis, whereas vedolizumab, a gut selective anti-integrin alpha4beta7 monoclonal antibody that is not associated with impaired systemic immune responses, is approved to treat Crohn’s disease and ulcerative colitis in adults.

A previous study from Kennedy and colleagues revealed that IBD patients on infliximab showed a weakened COVID-19 antibody response compared with patients on vedolizumab. To determine if treatment with anti-TNF drugs impacted the efficacy of the first shot of these two-dose COVID-19 vaccines, the researchers used data from the CLARITY IBD study to assess 865 infliximab- and 428 vedolizumab-treated participants without evidence of prior SARS-CoV-2 infection who had received uninterrupted biologic therapy since being recruited between Sept. 22 and Dec. 23, 2020.

In the 3-10 weeks after initial vaccination, geometric mean concentrations for SARS-CoV-2 anti-spike protein receptor-binding protein antibodies were lower in patients on infliximab, compared with patients on vedolizumab for both the Pfizer (6.0 U/mL [5.9] versus 28.8 U/mL [5.4], P < .0001) and AstraZeneca (4.7 U/mL [4.9] versus 13.8 U/mL [5.9]; P < .0001) vaccines. The researchers’ multivariable models reinforced those findings, with antibody concentrations lower in infliximab-treated patients for both the Pfizer (fold change, 0.29; 95% confidence interval, 0.21-0.40; P < .0001) and AstraZeneca (FC, 0.39; 95% CI, 0.30-0.51; P < .0001) vaccines.

After second doses of the two-dose Pfizer vaccine, 85% of patients on infliximab and 86% of patients on vedolizumab seroconverted (P = .68); similarly high seroconversion rates were seen in patients who had been infected with SARS-CoV-2 prior to receiving either vaccine. Several patient characteristics were associated with lower antibody concentrations regardless of vaccine type: being 60 years or older, use of immunomodulators, having Crohn’s disease, and being a smoker. Alternatively, non-White ethnicity was associated with higher antibody concentrations.

Evidence has ‘unclear clinical significance’

“These data, which require peer review, do not change my opinion on the safety and efficacy of COVID-19 vaccines in patients taking TNF inhibitors such as infliximab as monotherapy for the treatment of psoriatic disease,” Joel M. Gelfand MD, director of the psoriasis and phototherapy treatment center at the University of Pennsylvania, Philadelphia, said in an interview.

“First, two peer-reviewed studies found good antibody response in patients on TNF inhibitors receiving COVID-19 vaccines (doi: 10.1136/annrheumdis-2021-220289; 10.1136/annrheumdis-2021-220272). Second, antibody responses were robust in the small cohort that received the second dose of a COVID-19 vaccine. We already know that, for the two messenger RNA-based vaccines available under emergency use authorization in the U.S., a second dose is required for optimal efficacy. Thus, evidence of a reduced antibody response after just one dose is of unclear clinical significance. Third, antibody responses are only a surrogate marker, and a low antibody response doesn’t necessarily mean the patient will not be protected by the vaccine.”
 

Focus on the second dose of a two-dose regimen

“Tell me about the response in people who got both doses of a vaccine that you’re supposed to get both doses of,” Jeffrey Curtis, MD, professor of medicine in the division of clinical immunology and rheumatology at the University of Alabama at Birmingham, said in an interview. “The number of patients in that subset was small [n = 27] but in my opinion that’s the most clinically relevant analysis and the one that patients and clinicians want answered.”

He also emphasized the uncertainty around what ‘protection’ means in these early days of studying COVID-19 vaccine responses. “You can define seroprotection or seroconversion as some absolute level of an antibody response, but if you want to say ‘Mrs. Smith, your antibody level was X,’ on whatever arbitrary scale with whoever’s arbitrary lab test, nobody actually knows that Mrs. Smith is now protected from SARS-CoV-2, or how protected,” he said.

“What is not terribly controversial is: If you can’t detect antibodies, the vaccine didn’t ‘take,’ if you will. But if I tell you that the mean antibody level was X with one drug and then 2X with another drug, does that mean that you’re twice as protected? We don’t know that. I’m fearful that people are looking at these studies and thinking that more is better. It might be, but we don’t know that to be true.”
 

Debating the cause of weakened immune responses

“The biological plausibility of being on an anti-TNF affecting your immune reaction to a messenger RNA or even a replication-deficient viral vector vaccine doesn’t make sense,” David T. Rubin, MD, professor of medicine at the University of Chicago and chair of the National Scientific Advisory Committee of the Crohn’s and Colitis Foundation, said in an interview.

“I’m sure immunologists may differ with me on this, but given what we have come to appreciate about these vaccine mechanisms, this finding doesn’t make intuitive sense. So we need to make sure that, when this happens, we look to the next studies and try to understand, was there any other confounder that may have resulted in these findings that was not adequately adjusted for or addressed in some other way?

“When you have a study of this size, you argue, ‘Because it’s so large, any effect that was seen must be real,’ ” he added. “Alternatively, to have a study of this size, by its very nature you are limited in being able to control for certain other factors or differences between the groups.”

That said, he commended the authors for their study and acknowledged the potential questions it raises about the single-shot Johnson & Johnson vaccine. “If you only get one and you’re on infliximab, this study implies that maybe that’s not enough,” he said. “Despite the fact that Johnson & Johnson was approved as a single dose, it may be necessary to think about it as the first of two, or maybe it’s not the preferred vaccine in this group of patients.”

The study was supported by the Royal Devon and Exeter and Hull University Hospital Foundation NHS Trusts and unrestricted educational grants from Biogen (Switzerland), Celltrion Healthcare (South Korea), Galapagos NV (Belgium), and F. Hoffmann-La Roche (Switzerland). The authors acknowledged numerous potential conflicts of interest, including receiving grants, personal fees, and nonfinancial support from various pharmaceutical companies.

That said, he commended the authors for their study and acknowledged the potential questions it raises about the single-shot Johnson & Johnson vaccine. “If you only get one and you’re on infliximab, this study implies that maybe that’s not enough,” he said. “Despite the fact that Johnson & Johnson was approved as a single dose, it may be necessary to think about it as the first of two, or maybe it’s not the preferred vaccine in this group of patients.”

The study was supported by the Royal Devon and Exeter and Hull University Hospital Foundation NHS Trusts and unrestricted educational grants from Biogen (Switzerland), Celltrion Healthcare (South Korea), Galapagos NV (Belgium), and F. Hoffmann-La Roche (Switzerland). The authors acknowledged numerous potential conflicts of interest, including receiving grants, personal fees, and nonfinancial support from various pharmaceutical companies.

Children and adolescents with Prader-Willi syndrome (PWS) who received three daily, intranasal doses of carbetocin, an investigational, long-acting oxytocin analogue, had significant improvement in hyperphagia and anxiety during 8 weeks on treatment, compared with placebo in a multicenter, phase 3 trial with 119 patients.

The treatment also appeared safe during up to 56 additional weeks on active treatment, with no serious adverse effects nor “unexpected” events, and once completing the study about 95% of enrolled patients opted to remain on active treatment, Cheri L. Deal, MD, PhD, said at the annual meeting of the Endocrine Society.

Based on “the significant results for the placebo-controlled period, as well as for those finishing the 56-week extension, we may well have a new armament for helping these kids and their families deal with the unrelenting hunger of patients with PWS as well as some of the behavioral symptoms,” Dr. Deal, chief of endocrinology and diabetes at the Sainte-Justine Mother-Child University of Montreal Hospital, said in an interview. No treatment currently has labeling for addressing the hyperphagia or anxiety that is characteristic and often problematic for children and adolescents with PWS, an autosomal dominant genetic disease with an incidence of about 1 in 15,000 births and an estimated U.S. prevalence of about 9,000 cases, or about 1 case for every 37,000 people.
 

‘Gorgeous’ safety

“The results looked pretty positive, and we’re encouraged by what appears to be a good safety profile, so overall I think the PWS community is very excited by the results and is very interested in getting access to this drug,” commented Theresa V. Strong, PhD, director of research programs for the Foundation for Prader-Willi Research in Walnut, Calif., a group not involved with the study. Currently, “we have no effective treatments for these difficult behaviors” of hyperphagia and anxiety. Surveys and studies run by the foundation have documented that hyperphagia and anxiety “were the two most important symptoms that families would like to see treated,” Dr. Strong added in an interview.

PWS “is complex and affects almost every aspect of the lives of affected people and their families. Any treatment that can chip away at some of the problems these patients have can be a huge benefit to the patients and their families,” said Jennifer L. Miller, MD, a professor of pediatric endocrinology at the University of Florida, Gainesville, and a coinvestigator on the study.

But the finding that carbetocin appeared to address, at least in part, this unmet need while compiling a safety record that Dr. Miller called “gorgeous” and “remarkable,” also came with a few limitations.
 

Fewer patients than planned, and muddled outcomes

The CARE-PWS trial aimed to enroll 175 patients, but fell short once the COVID-19 pandemic hit. Plus the trial had two prespecified primary endpoints – improvements in a measure of hyperphagia, and in a measure of obsessive and compulsive behaviors – specifically in the 40 patients who received the higher of the two dosages studied, 9.6 mg t.i.d. intranasally. Neither endpoint showed significant improvement among the patients on this dosage, compared with the 40 patients who received placebo, although both outcomes trended in the right direction in the actively treated patients.

The study’s positive results came in a secondary treatment group, 39 patients who received 3.2 mg t.i.d., also intranasally. This subgroup had significant benefit, compared with placebo, for reducing hyperphagia symptoms as measured on the Hyperphagia Questionnaire for Clinical Trials (HQ-CT) Total Score. After the first 8 weeks on treatment, patients on the lower carbetocin dosage had an average reduction in their HQ-CT score of greater than 5 points, more than double the reduction seen among control patients who received placebo.

Those on the 3.2-mg t.i.d. dosage also showed significant improvements, compared with placebo, for anxiety, measured by the PWS Anxiety and Distress Questionnaire Total Score, as well as on measures of clinical global impression of severity, and of clinical global impression of change. Like the higher-dosage patients the lower-dosage subgroup did not show a significant difference compared with placebo for the other primary endpoint, change in obsessive and compulsive behaviors as measured by the Children’s Yale-Brown Obsessive-Compulsive Scale Total Score, although also like the higher dosage the effect from the lower dosage trended toward benefit.

A further limitation was that, at the time of her report, presented in abstract OR16-3 at the meeting, Dr. Deal could only present complete 64-week follow-up for 72 patients, although this reassuringly showed that, as time on the 9.6-mg t.i.d. dosage continued beyond 8 weeks, patients gradually improved their HQ-CT response so that by 64 weeks on treatment their hyperphagia score had improved as much as in the patients who received the lower dosage.

In short, documented benefits occurred on the lower dosage, especially for clinically meaningful symptoms like hyperphagia and anxiety, but the study’s overall results were not fully consistent by statistical criteria.

Benefiting an unmet need?

“While it is regrettable that we did not get to 175 patients because of COVID-19, the dataset is significant enough for me to feel that the FDA [Food and Drug Administration] needs to take a very serious look and consider approval,” Dr. Deal said in an interview. “Once safety is assured, which I think it is, I can only hope that regulatory officials understand their unmet needs of this rare disease community and will allow the drug to move to the next stage.”

“This is a very rare disease, and having families participate in trials is really challenging,” especially while the COVID-19 pandemic continues, Dr. Strong said. For the pediatric and adolescent patients targeted in this study “it will take a while for COVID to go away and for families to feel safe again being in a trial, so a real concern is that a need for more clinical trials is not terribly feasible now. Given that the safety profile looked good and one dose seemed to have good efficacy, as long as the long-term data continue to look good we’d love for the FDA to look at the existing data and see whether there is a path forward.”

Dr. Miller highlighted the limitations of what the CARE-PWS findings show.

“Given that it was only an 8-week trial of drug against placebo, and the fact that the primary outcomes weren’t met for the higher dose, my thought is that potentially we need to study more patients for a longer period at the 3.2-mg dose,” she said. She acknowledged that the metric used in the study to assess obsessive and compulsive behaviors is “very difficult” to apply to patients with PWS because of uncertainties in scoring obsessions in patients “who are not very good at telling you what they’re thinking.” Plus, “it’s absolutely not a problem that we did not see an effect on obsession and compulsions if the treatment potentially improves anxiety and hyperphagia, which are very common.” A treatment that reliably reduces these symptoms “would be amazing,” Dr. Miller added.

“PWS is very rare, so it’s very hard to do trials. Maybe the FDA will approve carbetocin because it was safe and gave a signal of efficacy at the lower dose. But my thought is that additional treatment trials are needed with only the lower dose and with longer duration,” she said.

CARE-PWS enrolled patients with nutritional phase 3 PWS who were aged 7-18 years at any of 24 sites in the United States, Canada, or Australia during 2018-2020. They averaged about 12 years of age, and 56% were girls.

The most common adverse effect from carbetocin was flushing, occurring in 14% of those on the lower dose and 21% on the higher dose, but not in any placebo patient. Other adverse effects more common on the lower dose than in the placebo group included headache in 16%, and diarrhea in 9%.

Carbetocin is not only long-lasting in circulation, it also has better affinity for oxytocin receptors than for vasopressin receptors, reducing the potential for causing hyponatremia. The idea to use it in patients with PWS followed prior studies with oxytocin, which had shown dopamine interactions that reduced anxiety and influenced food ingestion behavior. Brain autopsy studies had shown that patients with Prader-Willi syndrome have substantially fewer neurons than usual producing oxytocin. Treatment with intranasal carbetocin had shown efficacy for improving hyperphagia and behavior in a controlled phase 2 study with 37 patients.

Carbetocin is approved for use in reducing excessive bleeding after childbirth, particularly cesarean, in more than 20 countries outside the United States.

CARE-PWS was sponsored by Levo Therapeutics, the company developing carbetocin. Dr. Deal has been an adviser to Levo Therapeutics. Dr. Strong is an employee of the Foundation for Prader-Willi Research, which has received support from Levo Therapeutics as well as from other drug companies, but which receives most of its funding from individuals. Dr. Miller has received research funding from Levo Therapeutics and also from Harmony Biosciences, Rhythm Pharmaceuticals, and Soleno Therapeutics.

New cases of COVID-19 in children in the United States fell slightly, but even that small dip was enough to reverse 2 straight weeks of increases, according to a report from the American Academy of Pediatrics and the Children’s Hospital Association.

New cases totaled 63,862 for the latest reporting week, March 26 to April 1, compared with 64,029 for the previous week, the AAP and the CHA said in their weekly COVID-19 report. For the week ending April 1, children represented 18.1% of all new cases reported in the United States, down from a pandemic-high 19.1% the week before.

COVID-19 cases in children now total just under 3.47 million, which works out to 13.4% of reported cases for all ages and 4,610 cases per 100,000 children since the beginning of the pandemic, the AAP and the CHA said based on data from 49 states (excluding New York), the District of Columbia, New York City, Puerto Rico, and Guam.

Among those jurisdictions, Vermont has the highest proportion of its cases occurring in children at 21.0%, and North Dakota has the highest cumulative rate at 8,958 cases per 100,000 children. Looking at those states from the bottoms of their respective lists are Florida, where children aged 0-14 years represent 8.4% of all cases, and Hawaii, with 1,133 cases per 100,000 children aged 0-17 years, the AAP/CHA report shows.

The data on more serious illness show that Minnesota has the highest proportion of hospitalizations occurring in children at 3.1%, while New York City has the highest hospitalization rate among infected children, 2.0%. Among the other 23 states reporting on such admissions, children make up only 1.3% of hospitalizations in Florida and in New Hampshire, which also has the lowest hospitalization rate at 0.1%, the AAP and CHA said.

Five more deaths were reported in children during the week ending April 1, bringing the total to 284 in the 43 states, along with New York City, Puerto Rico, and Guam, that are sharing age-distribution data on mortality.

The increases seem to be driven by greater circulation of more contagious variants, just as children and teens have returned to in-person activities such as sports, parties, and classes.

“I can just tell you from my 46 years in the business, I’ve never seen dynamic transmission in kids like we’re seeing right now, younger kids,” said Michael Osterholm, PhD, who directs the Center for Infectious Disease Research and Policy at the University of Minnesota, Minneapolis.

In earlier surges, children – especially younger children – played only minor roles in transmitting the infection. When they were diagnosed with COVID-19, their symptoms tended to be mild or even absent, and for reasons that aren’t well understood, they haven’t usually been the first cases in households or clusters. 

Now, as more SARS-CoV-2 variants have begun to dominate, and seniors gain protection from vaccines, that pattern may be changing. Infectious disease experts are watching to see if COVID-19 will start to spread in a pattern more similar to influenza, with children becoming infected first and bringing the infection home to their parents.
 

Michigan sees jump in cases

Governors in some hard-hit states are pleading with a pandemic-weary public to keep up mask-wearing and social distancing and avoid unnecessary travel and large gatherings in order to protect in-person classes. 

In Michigan, many schools reopened and youth sports resumed just as the more contagious B.1.1.7 variant spread widely. There, cases are rising among all age groups, but the largest number of new COVID-19 cases is among children aged 10-19, the first time that’s happened since the start of the pandemic.

Over the month of March, incidence in this age group had more than doubled in the state. Cases among younger children – infants through 9-year-olds – are also going up, increasing by more than 230% since Feb. 19, according to data from the Michigan Department of Health and Human Services. 

The increases have prompted some schools to pause in-person learning for a time after spring break to slow transmission, according to Natasha Bagdasarian, MD, senior public health physician with the Michigan health department in Ann Arbor.

In Minnesota, on a recent call with reporters, Ruth Lynfield, MD, state epidemiologist, said the B.1.1.7 variant, which has rapidly risen in the state, has a higher attack rate among children than that of earlier versions of the virus, meaning they’re more likely to be infected when exposed.

“We certainly get the sense that youth are what we might refer to as the leading edge of the spread of variants,” she said.

Dr. Lynfield said they were tracking cases spreading through youth sports, classrooms, and daycare centers.

In Massachusetts, the largest number of new COVID-19 infections in the last 2 weeks of March was among children and teens. Massachusetts has the fifth-highest number of recorded B.1.1.7 cases in the United States, according to CDC data.

Although most COVID-19 cases in children and teens are mild, the disease can be severe for those who have underlying medical conditions. Even in healthy children, it can trigger a serious postviral syndrome called MIS-C that requires hospitalization. 

Emerging studies show that children, like adults, can develop the lingering symptoms of long COVID-19. Recent data from the United Kingdom show 10%-15% of children younger than 16 infected with COVID-19 still had at least one symptom 5 weeks later.

Dr. Osterholm said it remains to be seen whether more cases in children will also mean a rise in more serious outcomes for children, as it has in Europe and Israel.

In Israel, the B.1.1.7 variant arrived at the end of December and became dominant in January. By the end of January, Hadassah Ein Kerem Medical Center in Jerusalem had four patients in its newly opened pediatric COVID-19 ICU unit. They ranged in age from 13 days to 2 years.

By early February, the Ministry of Health warned the country’s doctors to prepare for an “imminent upward trend” in pediatric COVID-19 cases. They notified hospitals to be ready to open more ICU beds for children with COVID-19, according to Cyrille Cohen, PhD, head of the laboratory of immunotherapy at Bar-Ilan University in Ramat Gan, Israel.

On March 31, French President Emmanuel Macron ordered France into its third national lockdown and closed schools for 3 weeks to try to hold off a third wave of COVID-19. President Macron had been a staunch defender of keeping schools open, but said the closure was necessary. 

“It is the best solution to slow down the virus,” he said, according to Reuters.

German Chancellor Angela Merkel recently announced a new lockdown for Germany as the spread of the variants has led to rising cases there.

“I think what we’re seeing here is this is going to play out over the country,” said Dr. Osterholm. “Before this time, we didn’t see major transmission in younger kids particularly K through eighth grade, and now we’re seeing that happening with many school outbreaks, particularly in the Northeast and in the Midwest.” He added that it will spread through southern states as well.
 

Fall surge all over again

“It’s starting to feel an awful lot like déjà vu, where the hospitalization numbers, the positivity rate, all of the metrics that we track are trending up significantly, and it’s feeling like the fall surge,” said Brian Peters, CEO of the Michigan Hospital Association. “It’s feeling in many ways like the initial surge a year ago.”

Mr. Peters said that in January and February, COVID-19 hospitalizations in Michigan were less than 1,000 a day. Recently, he said, there were 2,558 people hospitalized with COVID-19 in Michigan.

About half of adults aged 65 and older have been fully vaccinated in Michigan. That’s led to a dramatic drop in cases and hospitalizations among seniors, who are at highest risk of death. At the same time, Gov. Gretchen Whitmer and health officials with the Biden administration have encouraged schools to reopen for in-person learning, and extracurricular activities have largely resumed.

The same circumstances – students in classrooms, combined with the arrival of the variants – resulted in COVID-19 cases caused by the B.1.1.7 variant increasing  among younger age groups in the United Kingdom. 

When schools were locked down again, however, cases caused by variant and wild type viruses both dropped in children, suggesting that there wasn’t anything that made B.1.1.7 extra risky for children, but that the strain is more contagious for everyone. Sports, extracurricular activities, and classrooms offered the virus plenty of opportunities to spread.

In Michigan, Dr. Bagdasarian said the outbreaks in children started with winter sports.

“Not necessarily transmission on the field, but we’re really talking about social gatherings that were happening in and around sports,” like the pizza party to celebrate a team win, she said, “and I think those social gatherings were a big driver.”

“Outbreaks are trickling over into teams and trickling over into schools, which is exactly what we want to avoid,” she added.

Thus far, Michigan has been reserving vaccine doses for older adults but will open eligibility to anyone age 16 and older starting on April 6.

Until younger age groups can be vaccinated, Mr. Peters said people need to continue to be careful.

“We see people letting their guard down and it’s to be expected,” Mr. Peters said. “People have COVID fatigue, and they are eager to get together with their friends. We’re not out of the woods yet.”
 

Children ‘heavily impacted’

In Nebraska, Alice Sato, MD, PhD, hospital epidemiologist at Children’s Hospital and Medical Center in Omaha, said they saw an increase in MIS-C cases after the winter surges, and she’s watching the data carefully as COVID-19 cases tick up in other midwestern states.

Dr. Sato got so tired of hearing people compare COVID-19 to the flu that she pulled some numbers on pediatric deaths.

While COVID-19 fatality rates in children are much lower than they are for adults, at least 279 children have died across the United States since the start of the pandemic. The highest number of confirmed pediatric deaths recorded during any of the previous 10 flu seasons was 188, according to the CDC.

“So while children are relatively spared, they’re still heavily impacted,” said Dr. Sato.

She was thrilled to hear the recent news that the Pfizer vaccine works well in children aged 12-15, but because Pfizer’s cold-chain requirements make it one the trickiest to store, the Food and Drug Administration hasn’t given the go-ahead yet. She said it will be months before she has any to offer to teens in her state. 

In the meantime, genetic testing has shown that the variants are already circulating there.

“We really want parents and family members who are eligible to be vaccinated because that is a great way to protect children that I cannot vaccinate yet,” Dr. Sato said. “The best way for me to protect children is to prevent the adults around them from being infected.”

Screen time may be associated with a range of psychosocial symptoms at age 5 years, according to a study of Finnish children that was published online in BMJ Open

Janette Niiranen, a researcher in the department of public health solutions at the Finnish Institute for Health and Welfare in Helsinki, and colleagues examined the frequency of electronic media use by 699 preschool children.

They analyzed longitudinal associations between media use at age 18 months and psychosocial symptoms at age 5 years. They also looked at whether media use at age 5 years was associated with the presence of psychosocial symptoms at that time.

The study relied on data collected between 2011 and 2017 as part of the Finnish CHILD-SLEEP longitudinal birth cohort study. Parents reported child media use via questionnaires at age 18 months and age 5 years. Researchers measured psychosocial symptoms at age 5 years using two parent-reported questionnaires: Five-to-Fifteen (FTF) and the Strengths and Difficulties Questionnaire (SDQ).

At age 5 years, a high amount of total screen time – at least 135 minutes per day, representing the 75th percentile of use – was associated with increased likelihood of attention and concentration difficulties, hyperactivity and impulsivity, emotional internalizing and externalizing symptoms, and conduct problems, the researchers reported. Odds ratios ranged from 1.57 to 2.18. In a model that adjusted for confounding factors, internalizing symptoms was the only symptom significantly associated with screen time (OR, 2.01).

In a longitudinal analysis, increased media use at 18 months was associated with peer problems at age 5 years (OR, 1.59).

Compared with program viewing, electronic game playing at age 5 years appeared to be associated with fewer psychosocial risks, the researchers noted. In an unadjusted model, a high amount of game playing was associated with hyperactivity, whereas program viewing was associated with a broad range of symptoms.

Use of electronic media beyond recommended amounts was common.

“The results of our study show that 95% of preschool aged children exceed the recommended daily e-media use of 1 hour,” the authors wrote.
 

No causal link

Amy Orben, DPhil, a researcher at Emmanuel College and the MRC Cognition and Brain Sciences Unit, University of Cambridge (England) highlighted limitations of the research.

The study is “purely observational” and does not “establish a causal link between time spent on electronic media and developmental outcomes in small children,” Dr. Orben said. Factors that may influence how much time a child spends on electronic media – such as whether both parents work and where a child lives – may also influence psychosocial symptoms.

“This means that an association can exist even if no causal link is present,” Dr. Orben said. Furthermore, the statistically significant associations found in the study “could well be noise,” she added.

As the study authors note, associations between screen time and children’s psychosocial well-being “may be bidirectional,” commented Karalyn Kinsella, MD, a pediatrician in private practice in Cheshire, Conn.

“There is no way to tell if the families who allow more screen time are doing that because the child already has some psychosocial issues like hyperactivity or dysregulation, and they are using media to calm them,” Dr. Kinsella said. “Or perhaps parents do not have the ability to interact as much with the child due to lack of time/work.” The lack of interaction, rather than electronic media use, may interfere with typical development.

“The end result is still pertinent, as we know children learn through play and social interaction,” Dr. Kinsella added. “I did find it interesting that electronic game playing when played with friends or family was less of a risk.”
 

Brainstorming alternatives

Libby Matile Milkovich, MD, a developmental pediatrician at Children’s Mercy Hospital, Kansas City, Mo., sees family electronic media use as an environmental factor that has significant variability for each patient.

“The need for electronic media to connect to others, to access entertainment, and to learn intensified with the pandemic,” Dr. Milkovich said. “In practice, after I identify concerning media habits, I try to help families create alternatives to their current habits as opposed to being prescriptive and saying to stop or limit media use. ... An alternative may not be limiting screen time but may be changing to more appropriate media content or sharing the media as a family activity.”

Seeing media use in the clinic can provide useful information and opportunities for discussion, Dr. Milkovich noted.

“When I see parents in the clinic room using media to calm a toddler or using their own media, these are great opportunities to open the door to brainstorming alternatives,” Dr. Milkovich said. “Commonly, family media use comes up when children have difficulty sleeping or disruptive behaviors related to media use, but I would challenge medical providers to think about problematic media use in all chief complaints where a behavioral component exists like toileting and feeding.”

The research was supported by the Academy of Finland, the Signe and Ane Gyllenberg Foundation, the Yrjö Jahnsson Foundation, the Foundation for Pediatric Research, the Finnish Cultural Foundation, and the Tampere University Hospital and Doctors’ Association in Tampere. The study authors, Dr. Milkovich, Dr. Orben, and Dr. Kinsella had no relevant financial disclosures. Dr. Kinsella serves on the Pediatric News editorial advisory board.

As the study authors note, associations between screen time and children’s psychosocial well-being “may be bidirectional,” commented Karalyn Kinsella, MD, a pediatrician in private practice in Cheshire, Conn.

“There is no way to tell if the families who allow more screen time are doing that because the child already has some psychosocial issues like hyperactivity or dysregulation, and they are using media to calm them,” Dr. Kinsella said. “Or perhaps parents do not have the ability to interact as much with the child due to lack of time/work.” The lack of interaction, rather than electronic media use, may interfere with typical development.

“The end result is still pertinent, as we know children learn through play and social interaction,” Dr. Kinsella added. “I did find it interesting that electronic game playing when played with friends or family was less of a risk.”
 

Brainstorming alternatives

Libby Matile Milkovich, MD, a developmental pediatrician at Children’s Mercy Hospital, Kansas City, Mo., sees family electronic media use as an environmental factor that has significant variability for each patient.

“The need for electronic media to connect to others, to access entertainment, and to learn intensified with the pandemic,” Dr. Milkovich said. “In practice, after I identify concerning media habits, I try to help families create alternatives to their current habits as opposed to being prescriptive and saying to stop or limit media use. ... An alternative may not be limiting screen time but may be changing to more appropriate media content or sharing the media as a family activity.”

Seeing media use in the clinic can provide useful information and opportunities for discussion, Dr. Milkovich noted.

“When I see parents in the clinic room using media to calm a toddler or using their own media, these are great opportunities to open the door to brainstorming alternatives,” Dr. Milkovich said. “Commonly, family media use comes up when children have difficulty sleeping or disruptive behaviors related to media use, but I would challenge medical providers to think about problematic media use in all chief complaints where a behavioral component exists like toileting and feeding.”

The research was supported by the Academy of Finland, the Signe and Ane Gyllenberg Foundation, the Yrjö Jahnsson Foundation, the Foundation for Pediatric Research, the Finnish Cultural Foundation, and the Tampere University Hospital and Doctors’ Association in Tampere.

Screen time may be associated with a range of psychosocial symptoms at age 5 years, according to a study of Finnish children that was published online in BMJ Open

Janette Niiranen, a researcher in the department of public health solutions at the Finnish Institute for Health and Welfare in Helsinki, and colleagues examined the frequency of electronic media use by 699 preschool children.

They analyzed longitudinal associations between media use at age 18 months and psychosocial symptoms at age 5 years. They also looked at whether media use at age 5 years was associated with the presence of psychosocial symptoms at that time.

The study relied on data collected between 2011 and 2017 as part of the Finnish CHILD-SLEEP longitudinal birth cohort study. Parents reported child media use via questionnaires at age 18 months and age 5 years. Researchers measured psychosocial symptoms at age 5 years using two parent-reported questionnaires: Five-to-Fifteen (FTF) and the Strengths and Difficulties Questionnaire (SDQ).

At age 5 years, a high amount of total screen time – at least 135 minutes per day, representing the 75th percentile of use – was associated with increased likelihood of attention and concentration difficulties, hyperactivity and impulsivity, emotional internalizing and externalizing symptoms, and conduct problems, the researchers reported. Odds ratios ranged from 1.57 to 2.18. In a model that adjusted for confounding factors, internalizing symptoms was the only symptom significantly associated with screen time (OR, 2.01).

In a longitudinal analysis, increased media use at 18 months was associated with peer problems at age 5 years (OR, 1.59).

Compared with program viewing, electronic game playing at age 5 years appeared to be associated with fewer psychosocial risks, the researchers noted. In an unadjusted model, a high amount of game playing was associated with hyperactivity, whereas program viewing was associated with a broad range of symptoms.

Use of electronic media beyond recommended amounts was common.

“The results of our study show that 95% of preschool aged children exceed the recommended daily e-media use of 1 hour,” the authors wrote.
 

No causal link

Amy Orben, DPhil, a researcher at Emmanuel College and the MRC Cognition and Brain Sciences Unit, University of Cambridge (England) highlighted limitations of the research.

The study is “purely observational” and does not “establish a causal link between time spent on electronic media and developmental outcomes in small children,” Dr. Orben said. Factors that may influence how much time a child spends on electronic media – such as whether both parents work and where a child lives – may also influence psychosocial symptoms.

“This means that an association can exist even if no causal link is present,” Dr. Orben said. Furthermore, the statistically significant associations found in the study “could well be noise,” she added.

As the study authors note, associations between screen time and children’s psychosocial well-being “may be bidirectional,” commented Karalyn Kinsella, MD, a pediatrician in private practice in Cheshire, Conn.

If everything goes as planned, the Pfizer and Moderna mRNA COVID-19 vaccines could be granted emergency use authorization (EUA) for children aged 12 years and older by the fall of 2021.

According to Yvonne Maldonado, MD, Pfizer has fully enrolled adolescent trials and Moderna is currently enrolling 3,000 adolescents in a safety and reactogenicity trial known as TeenCOVE, in which participants will receive an intramuscular injection of 100 mcg mRNA-1273 on day 1 and on day 29. Meanwhile, Johnson & Johnson and AstraZeneca will be starting to enroll older children and adolescents into studies within the next several weeks.

The companies are also planning to enroll younger children, Dr. Maldonado, the Taube professor of global health and infectious diseases at Stanford (Calif.) University, said during the Society for Pediatric Dermatology pre-AAD meeting. “At least two of the vaccine companies have indicated that they would like to start enrolling children as young as 2-5 years of age and eventually getting down to infants and toddlers if the vaccines prove to be safe and effective in the older children. Eventually, we hope to get to the level where we can have several vaccine candidates for all children 6 months of age and older.”

In the future, she said, infectious disease experts hope to see antiviral, immunomodulatory, anti-inflammatory, and monoclonal therapies for all populations including children, although trials in this population have not begun. “Clinical trials must be flexible and adaptive to deal with children and adolescents,” added Dr. Maldonado, who is also senior associate dean for faculty development and diversity at Stanford.

“We would ideally like to have new correlates of protection, as well as biomarkers to follow for evidence of effectiveness. We also would love to see vaccines in the pediatric population as soon as possible, because herd immunity is the ultimate goal for protection against this disease and prevention of additional transmission over time.” However, she said, the degree and durability of immunity has yet to be determined, and vaccine-associated immune effects are unknown. In the meantime, infectious disease researchers expect nonpharmacologic interventions, such as wearing face masks and social distancing to continue for an undefined period.

(Less than 2 weeks after Dr. Maldonado spoke at the SPD meeting, Pfizer announced in a press release that, in phase 3 clinical trials, the company’s coronavirus vaccine was 100% effective in protecting children aged 12-15 years from infection, with a “robust” antibody responses and side effects similar to those experienced by those aged 16-25 years. The company also announced that it plans to seek Food and Drug Administration EUA for this age group. Asked to comment on this update, Dr. Maldonado said the results released by Pfizer “suggest that their COVID-19 vaccine is very safe and highly effective in preventing COVID-19 among children 12-15 years of age.” She added that additional data from the Pfizer trials as well as from Moderna and Johnson & Johnson vaccine trials “will hopefully lead to FDA EUA review in the coming weeks,” and that COVID-19 vaccinations for children “may be possible by this summer.”)
 

_{Children with underlying diseases or on immune suppressants}

At the SPD meeting, an attendee asked if there were any pediatric patients for whom she would not recommend receiving a COVID-19 vaccine because of an underlying disease or concurrent therapy with immune suppressants. “We don’t have those data yet,” Dr. Maldonado said. “Based on what we’re seeing with adults, it does appear that those with underlying conditions are at somewhat higher risk of developing severe infection and may therefore most likely to need vaccination. Most of those risks are cardiovascular, obesity, and other factors, but not necessarily immunocompromising conditions. More likely what we’re seeing is that people with underlying immunocompromising conditions may not mount a good response to the vaccines at this time. It doesn’t mean we shouldn’t give the vaccines, but we need to learn more about that.”

Dr. Maldonado went on to note that, as vaccine manufacturers commence pediatric trials, healthy children will be tested first, followed in due time with children who have immunocompromised conditions. “The question will be whether or not we should give monoclonal antibodies to those particular children to help boost their immunity to SARS-CoV-2, because they might not have a good response to the vaccines,” she said. “Those things need to be sorted out, but there’s no safety signal or concerns at this point for vaccine to be given to immunocompromised individuals.”

Another meeting attendee asked Dr. Maldonado if she thinks there is a practical role for assessing markers of T-cell immunity when evaluating suspected COVID-19 patients who may test negative on serology, Dr. Maldonado said that she and her colleagues are seeking pediatric patients who were treated for COVID-19 at Stanford, in an effort to sort this out.

They are checking peripheral blood mononuclear cells in these patients “to try and tease out what the immune response is in kids who have serious disease, versus those who came in with acute disease, versus those who are asymptomatic,” and comparing them with children who don’t have infection, she explained. “The question is, what is the role of T cells and how much do they contribute? One of the biggest questions we have is, do we have an immune correlate? Can we detect a particular level of neutralizing antibody that seems to be protective? If so, how long is it protective, and can we look for T- and B-cell memory cells and effector vector cells and see how long those effector vector cells can be active in protection? Those are studies that are ongoing now.”

Dr. Maldonado disclosed that she is a member of the data safety monitoring board for a non–COVID-19 vaccine being developed by Pfizer.

More adolescent girls than boys experienced nonfatal opioid overdose and reported baseline levels of anxiety, depression, and self-harm, according to data from a retrospective cohort study of more than 20,000 youth in the United States.

Previous studies have identified sex-based differences in opioid overdose such as a higher prevalence of co-occurring psychiatric disorders in women compared with men, wrote Sarah M. Bagley, MD, of Boston University, and colleagues. “However, few studies have examined whether such sex-based differences in opioid overdose risk extend to the population of adolescents and young adults,” they said.

In a retrospective cohort study published in JAMA Network Open, the researchers identified 20,312 commercially insured youth aged 11-24 years who experienced a nonfatal opioid overdose between Jan. 1, 2006, and Dec. 31, 2017, and reviewed data using the IBM MarketScan Commercial Database. The average age of the study population was 20 years and approximately 42% were female.

Females aged 11-16 years had a significantly higher incidence of nonfatal opioid overdose (60%) compared with males, but this trend reversed at age 17 years, after which the incidence of nonfatal opioid overdose became significantly higher in males. “Our finding that females younger than 17 years had a higher incidence of NFOD is consistent with epidemiologic data that have indicated changes in alcohol and drug prevalence among female youths,” the researchers wrote.

Overall, 57.8% of the cohort had mood and anxiety disorders, 12.8% had trauma- or stress-related disorders, and 11.7% had attention-deficit/hyperactivity disorder.

When analyzed by sex, females had a significantly higher prevalence than that of males of mood or anxiety disorders (65.5% vs. 51.9%) trauma or stress-related disorders (16.4% vs. 10.1%) and attempts at suicide or self-harm (14.6% vs. 9.9%). Males had significantly higher prevalence than that of females of opioid use disorder (44.7% vs. 29.2%), cannabis use disorder (18.3% vs. 11.3%), and alcohol use disorder (20.3% vs. 14.4%).

“Although in our study, female youths had a lower prevalence of all substance use disorders, including OUD [opioid use disorder], and a higher prevalence of mood and trauma-associated disorders, both male and female youths had a higher prevalence of psychiatric illness and substance use disorder than youths in the general population,” the researchers noted.

The study findings were limited by several factors including the inclusion only of youth with commercial insurance, with no uninsured or publicly insured youth, and only those youth who sought health care after a nonfatal opioid overdose, the researchers noted. The prevalence of substance use and mental health disorders may be over- or underdiagnosed, and race was not included as a variable because of unreliable data, they added. The database also did not allow for gender identity beyond sex as listed by the insurance carrier, they said.

However, the results indicate significant differences in the incidence of nonfatal opioid overdose and accompanying mental health and substance use disorders based on age and sex, they said.

“These differences may have important implications for developing effective interventions to prevent first-time NFOD and to engage youths in care after an NFOD,” they concluded.

The study was supported by grants to several researchers from the National Institute on Drug Abuse, National Institutes of Health, and the Charles A. King Trust. The researchers had no financial conflicts to disclose.
