Pediatrics

The COVID-19 prevention effort in children enters its next phase as June draws to a close, while new pediatric cases continued on a downward trend and hospitalizations continued to rise.

The COVID-19 vaccines from Pfizer-BioNTech and Moderna were approved for use in children as young as 6 months, the Centers for Disease Control and Prevention announced on June 18.

“We know millions of parents and caregivers are eager to get their young children vaccinated. ... I encourage parents and caregivers with questions to talk to their doctor, nurse, or local pharmacist to learn more about the benefits of vaccinations,” CDC Director Rochelle P. Walensky, MD, MPH, said in a written statement.

There are, however, indications that many parents are not that eager. A survey conducted in April by the Kaiser Family Foundation showed that only about 18% of parents were eager to get their children under age 5 years vaccinated right away and 27% said they would “definitely not” get their children vaccinated. Another 11% said “they will only do so if they are required,” Kaiser noted.

The vaccination experience with children aged 5-11 years seems to agree with those numbers. As of June 16, more than 7 months after the vaccine became available, just over 36% had received at least one dose and about 30% were fully vaccinated, CDC data show.

There are, according to the American Academy of Pediatrics, still five states where less than 20% of eligible 5- to 11-year-olds have received an initial vaccination. Among children aged 12-17, uptake has been much higher: 70% have received at least one dose and 60% are fully vaccinated, the CDC said.

Trends for new cases, hospitalizations diverging

COVID incidence in children, meanwhile, dropped for the second time in 3 weeks. There were 83,000 new cases reported during June 10-16, a decline of 4.8% from the previous week, according to the AAP and the Children’s Hospital Association.

New cases had risen by a very slight 0.31% during the week of June 3-9 after dropping 22% the week before (May 27 to June 2). Total cases in children have surpassed 13.6 million, which represents 18.8% of cases in all ages since the start of the pandemic, the AAP and CHA said in their weekly COVID report.

New admissions of children with confirmed COVID-19, however, have continued to climb since early to mid April. On June 16, the rate for children aged 0-17 years was up to 0.31 per 100,000, compared with the 0.13 per 100,000 recorded as late as April 11, the CDC said on its COVID Data Tracker.

It’s no secret that the fitness level of all age groups in our country is poor. A recent study in Pediatrics sharpens the focus on the question of how we might address the problem in the teenage population. Based in England, the investigators placed wrist accelerometers on their 13- and 14-year-old subjects who were then assessed using shuttle runs at progressively faster speeds.

The researchers found that the participants’ cardiorespiratory fitness improved as the subjects’ time doing vigorous activity increased up to 20 minutes and then plateaued. The study authors could not prove that the vigorous activity caused the increased in fitness. However, they were impressed by the plateau phenomenon and suggest that this might suggest a change in the recommendations by the World Health Organization and U.S. Department of Health & Human Services which currently call for 60 minutes of moderate to vigorous physical activity per day for adolescents

At first blush a shift down to 20 minutes of vigorous activity would appear to be workable and achievable. This would be particularly true for public school systems that are already struggling to get any kind of activity shoehorned into their schedules that are already crammed in an attempt to address mandated academic achievement goals. Freeing up an additional 40 minutes of the school day and yielding improved cardiorespiratory fitness sounds like a win-win.

But, let’s take a deep breath and for a few moments return to the world of reality. First, how many school systems are providing that 60 minutes of moderate activity (let’s forget the vigorous piece for the moment) included in the current WHO/HHS recommendations? Next, let’s take a look at what “vigorous” activity means. There are variety of definitions but in general they include sweating, flushing, and dyspnea to the point of having difficulty speaking.

Let’s just focus on the “sweating” part. To me that sounds like an activity that would require some wardrobe alteration at a minimum and very likely a locker room and a shower. Those can be fightin’ words for many teenagers. Even if a school can provide adequate locker room and shower infrastructure change-ups and showers are time-gobbling activities. And, more realistically, what are the chances of getting body image–challenged adolescents to willingly take advantage of them? You don’t have to talk to very many adults before you will hear stories of discomfort and embarrassment resulting from forced locker room and shower experiences. When I was a teenager the only way you could flunk physical education was to refuse to go in the locker room and “change up.” I think or at least hope that physical educators are more sensitive to the fragility of their adolescents students. But, the bottom line is that creating a curriculum that will improve cardiorespiratory fitness is fraught with challenges most school systems can’t address. It’s sad but true.

So, where does that leave us? This new study from England may be helpful for families who are caught in a time crunch and looking improve their fitness or for the physical educator who would like to help his/her motivated students get on a healthier track. But, this study should not prompt us to throw up our hands and toss out the current recommendations of an hour of moderate activity. As unrealistic as it may be for most school systems it allows for the injection of physical activity into academic settings where creative educators can offer things like walking lectures and field trips. It all boils down to the fact that some activity is better than none at all with or without the sweat equity.

Dr. Wilkoff practiced primary care pediatrics in Brunswick, Maine, for nearly 40 years. He has authored several books on behavioral pediatrics, including “How to Say No to Your Toddler.” Other than a Littman stethoscope he accepted as a first-year medical student in 1966, Dr. Wilkoff reports having nothing to disclose.

The social behavior associated with the COVID-19 pandemic may have reduced the incidence of Kawasaki disease, according to results of a cohort study of nearly 4,000 children.

The incidence of Kawasaki disease in the United States declined by 28.2% between 2018 and 2020, possibly as a result of factors including school closures, mask mandates, and reduced ambient pollution that might reduce exposure to Kawasaki disease (KD) in the environment, but a potential association has not been explored, wrote Jennifer A. Burney, PhD, of the University of California, San Diego, and colleagues.

KD received greater attention in the public and medical communities because of the emergence of multisystem inflammatory syndrome in children (MIS-C), which is similar to, but distinct from, KD, and because of the noticeable drop in KD cases during the pandemic, the researchers said.

In a multicenter cohort study published in JAMA Network Open , the researchers reviewed data from 2,461 consecutive patients with KD who were diagnosed between Jan. 1, 2018, and Dec. 31, 2020. They conducted a detailed analysis of analysis of 1,461 children with KD who were diagnosed between Jan. 1, 2002, and Nov. 15, 2021, at Rady Children’s Hospital San Diego (RCHSD), using data from before, during, and after the height of the pandemic. The median age of the children in the RCHSD analysis was 2.8 years, 62% were male, and 35% were Hispanic.

Overall, the prevalence of KD declined from 894 in 2018 to 646 in 2020, across the United States, but the decline was uneven, the researchers noted.

In the RCHSD cohort in San Diego, KD cases in children aged 1-5 years decreased significantly from 2020 to 2021 compared to the mean number of cases in previous years (22 vs. 44.9, P = .02). KD cases also decreased significantly among males and Asian children.

Notably, the occurrence of the KD clinical features of strawberry tongue, enlarged cervical lymph node, and subacute periungual desquamation decreased during 2020 compared with the baseline period, although only strawberry tongue reached statistical significance (39% vs. 63%, P = .04). The prevalence of patients with an enlarged lymph node was 21% in 2020 vs. 32% prior to the pandemic (P = .09); the prevalence of periungual desquamation during these periods was 47% vs. 58%, P = .16).

The researchers also used data from Census Block Groups (CBGs) to assess the impact of mobility metrics and environmental exposures on KD during the pandemic for the San Diego patient cohort. They found that KD cases during the pandemic were more likely to occur in neighborhoods of higher socioeconomic status, and that neighborhoods with lower levels of nitrous oxides had fewer KD cases.

Overall, “The reduction in KD case numbers coincided with masking, school closures, reduced circulation of respiratory viruses, and reduced air pollution,” the researchers wrote in their discussion of the findings. “A rebound in KD case numbers to prepandemic levels coincided with the lifting of mask mandates and, subsequently, the return to in-person schooling,” they wrote.

The study findings were limited by several factors including the small sample sizes, which also limit the interpretation of mobility and pollution data, the researchers noted. Other limitations include the high interannual variability of KD and the inclusion of 2021 rebound data from the San Diego region only.

“Although our original hypothesis was that shelter-in-place measures would track with reduced KD cases, this was not borne out by the San Diego region data. Instead, the San Diego case occurrence data suggest that exposures that triggered KD were more likely to occur in the home, with a shift toward households with higher SES during the pandemic,” the researchers noted. However, “The results presented here are consistent with a respiratory portal of entry for the trigger(s) of KD,” they said.
 

Study fails to validate its conclusions

“This study attempts to test the hypothesis that various social restrictions were associated with a decrease in rate of diagnosed Kawasaki disease cases during portions of the SARS-CoV-2 pandemic,” Mark Gorelik, MD, assistant professor of pediatrics at Columbia University, New York, said in an interview.

“However, it appears that it fails to achieve this conclusion and I disagree with the findings,” said Dr. Gorelik, who was not involved in the study but served as first author on an updated Kawasaki disease treatment guideline published earlier this spring in Arthritis & Rheumatology.

“The study does not find statistically significant associations either with shelter in place orders or with cell phone mobility data, as stated in the conclusion, directly contradicting its own claim,” Dr. Gorelik said. “Secondly, the study makes an assumption that various methods, especially the wearing of masks by children and school closures, had a significant effect on the spread of respiratory viruses. There are no prospective, population based, controlled real world studies that validate this claim, and two prospective controlled real-world studies that dispute this,” he emphasized. “Cloth masks and surgical masks, which were the types of masks worn by school students, are also known to have a nonsignificant and paltry – in the latter, certainly less than 50%, and perhaps as little as 10% – effect on the reduction of respiratory viral spread,” he added.

“Mechanistic studies on mask wearing may suggest some mask efficacy, but these studies are as valid as mechanistic studies showing the effect of various antifungal pharmaceuticals on the replication of SARS-CoV-2 virus in culture, meaning only valid as hypothesis generating, and ultimately the latter hypothesis failed to bear out,” Dr. Gorelik explained. “We do not know the reason why other respiratory viruses and non-SARS-CoV-2 coronaviruses declined during the pandemic, but we do know that despite this, the SARS-CoV-2 coronavirus itself did not appear to suffer the same fate. Thus, it is very possible that another factor was at work, and we know that during other viral pandemics, typically circulating viruses decline, potentially due to induction of interferon responses in hosts, in a general effect known as ‘viral interference,’ ” he said.

“Overall, we must have robust evidence to support benefits of hypotheses that have demonstrated clear damage to children during this pandemic (such as school closures), and this study fails to live up to that requirement,” Dr. Gorelik said.  

The study was supported by the Gordon and Marilyn Macklin Foundation and the Patient-Centered Outcomes Research Institute. Dr. Burney and Dr. Gorelik had no financial conflicts to disclose.

Overall, “The reduction in KD case numbers coincided with masking, school closures, reduced circulation of respiratory viruses, and reduced air pollution,” the researchers wrote in their discussion of the findings. “A rebound in KD case numbers to prepandemic levels coincided with the lifting of mask mandates and, subsequently, the return to in-person schooling,” they wrote.

The study findings were limited by several factors including the small sample sizes, which also limit the interpretation of mobility and pollution data, the researchers noted. Other limitations include the high interannual variability of KD and the inclusion of 2021 rebound data from the San Diego region only.

“Although our original hypothesis was that shelter-in-place measures would track with reduced KD cases, this was not borne out by the San Diego region data. Instead, the San Diego case occurrence data suggest that exposures that triggered KD were more likely to occur in the home, with a shift toward households with higher SES during the pandemic,” the researchers noted. However, “The results presented here are consistent with a respiratory portal of entry for the trigger(s) of KD,” they said.
 

Study fails to validate its conclusions

“This study attempts to test the hypothesis that various social restrictions were associated with a decrease in rate of diagnosed Kawasaki disease cases during portions of the SARS-CoV-2 pandemic,” Mark Gorelik, MD, assistant professor of pediatrics at Columbia University, New York, said in an interview.

“However, it appears that it fails to achieve this conclusion and I disagree with the findings,” said Dr. Gorelik, who was not involved in the study but served as first author on an updated Kawasaki disease treatment guideline published earlier this spring in Arthritis & Rheumatology.

“The study does not find statistically significant associations either with shelter in place orders or with cell phone mobility data, as stated in the conclusion, directly contradicting its own claim,” Dr. Gorelik said. “Secondly, the study makes an assumption that various methods, especially the wearing of masks by children and school closures, had a significant effect on the spread of respiratory viruses. There are no prospective, population based, controlled real world studies that validate this claim, and two prospective controlled real-world studies that dispute this,” he emphasized. “Cloth masks and surgical masks, which were the types of masks worn by school students, are also known to have a nonsignificant and paltry – in the latter, certainly less than 50%, and perhaps as little as 10% – effect on the reduction of respiratory viral spread,” he added.

“Mechanistic studies on mask wearing may suggest some mask efficacy, but these studies are as valid as mechanistic studies showing the effect of various antifungal pharmaceuticals on the replication of SARS-CoV-2 virus in culture, meaning only valid as hypothesis generating, and ultimately the latter hypothesis failed to bear out,” Dr. Gorelik explained. “We do not know the reason why other respiratory viruses and non-SARS-CoV-2 coronaviruses declined during the pandemic, but we do know that despite this, the SARS-CoV-2 coronavirus itself did not appear to suffer the same fate. Thus, it is very possible that another factor was at work, and we know that during other viral pandemics, typically circulating viruses decline, potentially due to induction of interferon responses in hosts, in a general effect known as ‘viral interference,’ ” he said.

“Overall, we must have robust evidence to support benefits of hypotheses that have demonstrated clear damage to children during this pandemic (such as school closures), and this study fails to live up to that requirement,” Dr. Gorelik said.  

The study was supported by the Gordon and Marilyn Macklin Foundation and the Patient-Centered Outcomes Research Institute. Dr. Burney and Dr. Gorelik had no financial conflicts to disclose.

During the coronavirus pandemic, several substance use behaviors decreased among youths, namely drinking, smoking, vaping, and cannabis use, according to a recent study published in the journal Current Psychiatry Reports.

That likely happened because they had to spend more time at home and less time with their friends, the study authors wrote, adding that youth substance use should be monitored in the post-pandemic years.

“One of the driving factors for youth substance use is access to substances,” Hannah Layman, one of the co-authors and a social and behavioral sciences doctoral student at West Virginia University, said in a statement.

“With stay-at-home orders, virtual schooling, and social distancing, children have been spending more time with family and are more socially isolated from peers than before,” she said. “Although social isolation from peers may have a negative impact on their mental health, it may just be one of the desirable outcomes of the pandemic when considering substance use in children.”

Ms. Layman and colleagues analyzed 49 studies that followed substance use of alcohol, cannabis, tobacco, e-cigarettes/vaping, and other drugs among children, teens, and youths under age 24. The studies spanned across several countries, including 22 in North America and 19 in Europe.

The research team found that most studies across all categories reported reductions in prevalence, except for the category of “other drugs and unspecific drugs,” which included three studies that showed an increase in use and three studies that showed a decrease in use.

Teens and preteens tend to have easier access to alcohol, tobacco, cannabis products, and vaping products and see them as less serious than “hard drugs,” the authors said.

Future research should analyze the long-term effects of the pandemic on youth substance use, the study authors wrote, paying attention to differences by gender and those who face the highest risks for substance use. Previous studies have shown an increase in substance use among youths, particularly among those in low-income neighborhoods or in difficult family circumstances.

“Substance use can affect a young person’s body in many ways, such as the development of mental health issues (depression, anxiety, conduct problems, personality disorders, and suicidal thoughts), injuries due to accidents, decreased bone mineral density, preventing proper brain growth and function, delayed puberty, liver damage, and so much more,” Ms. Layman said.

Increased parent or caregiver supervision can help prevent substance use problems, she noted. Early intervention, open support in conversations, and ongoing education about the dangers of substance use can help as well.

“Our findings also identified the importance of improving youth mental health and the value of telemedicine to address young people’s needs during the pandemic,” she said.

Symptoms of obstructive sleep apnea (OSA) were significantly more common in children with autism spectrum disorder (ASD), compared with controls, based on data from 166 individuals up to age 18 years.

Autism spectrum disorder affects approximately 1 in 54 children in the United States, and recent studies have shown an increased risk of obstructive sleep apnea in this population, compared with the general pediatric population, wrote Pooja Santapuram, MD, of Vanderbilt University, Nashville, Tenn., and colleagues.

In a study published in the International Journal of Pediatric Ototrhinolaryngology , the researchers reviewed data from 166 children and adolescents up to 18 years of age with OSA who underwent adenotonsillectomy at a single center between 2019 and 2021. The primary objective was to assess OSA symptoms in children with and without ASD. The study population included 75 children with ASD and 91 controls. The average age of both the ASD group and control group was approximately 73 months.
 

OSA meets ASD

Obstructive sleep apnea is common in autism spectrum disorder. Children with OSA can present with a range of symptoms, including loud snoring, excessive daytime sleepiness, and changes in cognitive function. Some of these symptoms can overlap with and exacerbate symptoms of ASD, potentially delaying OSA diagnosis in children with both conditions. The primary objective of this study was to assess between-group difference in OSA symptomatology and age at OSA diagnosis in children with and without ASD. To do so, a retrospective chart review was conducted on the 166 pediatric patients.

Overall, significantly more OSA symptoms were reported in children with ASD, compared with controls (P < .001).

Lower autism severity was associated with an increased number of reported OSA symptoms (P = .006). There was not a significant between-group difference in age at OSA diagnosis (P = .999); however, lower autism severity was also associated with an increased age at diagnosis (P = .002). These findings suggest that OSA may present with a higher symptom burden in children with ASD, and children with lower ASD severity often experience delays in OSA diagnosis.

Interestingly, despite the known associations between obesity and OSA, children with an increased body mass index were not diagnosed with OSA at an earlier age in this sample population, the researchers indicated.

Because the current study revealed that children with less severe ASD are more likely to report an increased number of OSA symptoms and be diagnosed at a later age than children without ASD, clinicians should have a heightened sense for OSA evaluation in children with ASD, particularly in children with a lower severity of ASD and an increased BMI, the researchers concluded.

The research study was not externally funded, and the researchers reported that they had no conflicts of interest.

Longer circadian periods and irregular sleep were significantly associated with mental health problems in adolescents including depression, anxiety, suicidality, social anxiety, and panic disorder, according to results from a European study.

A range of psychiatric symptoms and conditions has been linked to sleep pathologies, wrote Liisa Kuula, PhD, of the University of Helsinki, Finland, and colleagues. Some research suggests that late circadian rhythms and irregular sleep patterns increase the risk for psychiatric conditions, but the association has not been well studied, especially in adolescents, although the onset of psychiatric problems often occurs at this age, they said.

In a study published in the Journal of Psychiatric Research (2022 Apr 4. doi: 10.1016/j.jpsychires.2022.03.056.), the investigators reviewed data from 342 adolescents who were part of SleepHelsinki! a large cohort study of delayed sleep phase disorder (DSPD) in adolescents. The mean age of the participants was 17.4 years, and 70% were female.

The participants completed the Mini International Neuropsychiatric Interview (MINI) and wore temperature loggers for 3 days to assess circadian rhythms. The primary outcome was the impact of circadian dynamics on different psychiatric problems. Delayed Sleep Phase (DSP) behavior was defined as going to sleep later than 1 a.m. at least three times a week.

Circadian length was determined through the temperature loggers worn for 3 days. Most participants also completed 1-week GeneActiv Original actigraphy measurements (wearing the actigraph for 1 week) and responded to the Morningness-Eveningness Questionnaire, which divided participants into three circadian preference groups: morning, intermediate, and evening. Sleep duration was calculated as total sleep time, sleep quality was estimated by sleep efficiency, and sleep timing was assessed by the midpoint of the sleep period.

Overall, the MINI interview results suggested that approximately one-third (36%) of the teens had at least one psychiatric problem, and 21% had comorbid conditions.

Severe depression was significantly associated with a longer circadian period (P = .002), while suicidality was significantly associated with a later midpoint and more irregular sleep (P = .007 for both).

Participants with agoraphobia slept longer than did those without, the researchers noted (P = .013). However, sleep duration was not significantly associated with other psychiatric conditions.

Manic episodes and psychotic disorders were associated with irregular sleep timing (P < .018 and P < .017, respectively).

When the researchers examined DSP and circadian preferences, they found that 21.5% of individuals with suicidality had characteristics of DSP, as did 21.5% of those with panic disorder.

Individuals with a preference for eveningness were significantly more likely to meet criteria for severe depression, panic disorder, generalized anxiety disorder, and obsessive-compulsive disorder than were those without a preference for eveningness, the researchers noted.

“Our findings are the first to encompass diverse circadian measures alongside an array of psychiatric symptoms in such a focused age range,” the researchers wrote in their discussion. The data reflect results from other studies and extend the likely role of circadian patterns in mental wellbeing, they said.

The study findings were limited by several factors including the lack of actual diagnoses from medical records and use of self-reported symptoms, the researchers noted. Other limitations included the lack of polysomnography data and small size of subgroups of the study sample.

However, the results were strengthened by the heterogenous study population and use of multiple measures to examine sleep and circadian rhythms, as well as consideration of personal circadian preferences, the researchers said.

“The importance of overall synchronization with environment is perhaps best highlighted by response to treatment: most psychopathologic symptoms benefit from sleep-targeted therapeutic approaches,” they concluded.

The study received no outside funding. The researchers had no financial conflicts to disclose.

What would you do if you believed you had a serious health issue, but the best way to find out for sure might kill you?

That’s the reality for patients who wish to confirm or rule out a food allergy, says Sindy Tang, PhD, an associate professor of mechanical engineering at Stanford (Calif.) University.

And it’s the reason Dr. Tang and her colleagues are developing a food allergy test that’s not only safer, but also more reliable than today’s tests. In a paper in the journal Lab on a Chip, Dr. Tang and her colleagues outline the basis for this future test, which isolates a food allergy marker from the blood using a magnetic field.
 

How today’s food allergy tests fall short

The gold standard for food allergy diagnosis is something called the oral food challenge. That’s when the patient eats gradually increasing amounts of a problem food – say, peanuts – every 15 to 30 minutes to see if symptoms occur. This means highly allergic patients may risk anaphylaxis, an allergic reaction that causes inflammation so severe that breathing becomes restricted and blood pressure drops. Because of that, a clinical team must be at the ready with treatments like oxygen, epinephrine, or albuterol.

“The test is very accurate, but it’s also potentially unsafe and even fatal in rare cases,” Dr. Tang says. “That’s led to many sham tests advertised online that claim to use hair samples for food tests, but those are inaccurate and potentially dangerous, since they may give someone a false sense of confidence about a food they should avoid.”

Less risky tests are available, such as skin-prick tests – those involve scratching a small amount of the food into a patient’s arm – as well as blood tests that measure allergen-specific antibodies.

“Unfortunately, both of those are not that accurate and have high false-positive rates,” Dr. Tang says. “The best method is the oral food challenge, which many patients are afraid to do, not surprisingly.”
 

The future of food allergy testing: faster, safer, more reliable

In their study, the Stanford researchers focused on a type of white blood cell known as basophils, which release histamine when triggered by allergens. By using magnetic nanoparticles that bind to some blood cells but not basophils, they were able to separate basophils from the blood with a magnetic field in just 10 minutes.

Once isolated, the basophils are exposed to potential allergens. If they react, that’s a sign of an allergy.

Basophils have been isolated in labs before but not nearly this quickly and efficiently, Dr. Tang says.

“For true basophil activation, you need the blood to be fresh, which is challenging when you have to send it to a lab,” Dr. Tang says. “Being able to do this kind of test within a clinic or an in-house lab would be a big step forward.”
 

Next steps

While this represents a breakthrough in basophil activation testing, more research is needed to fully develop the system for clinical use. It must be standardized, automated, and miniaturized, the researchers say.

That said, the results give hope to those with food allergies that tomorrow’s gold-standard test will require only a blood sample without an emergency team standing by.

“Unfortunately, both of those are not that accurate and have high false-positive rates,” Dr. Tang says. “The best method is the oral food challenge, which many patients are afraid to do, not surprisingly.”
 

The future of food allergy testing: faster, safer, more reliable

In their study, the Stanford researchers focused on a type of white blood cell known as basophils, which release histamine when triggered by allergens. By using magnetic nanoparticles that bind to some blood cells but not basophils, they were able to separate basophils from the blood with a magnetic field in just 10 minutes.

Once isolated, the basophils are exposed to potential allergens. If they react, that’s a sign of an allergy.

Basophils have been isolated in labs before but not nearly this quickly and efficiently, Dr. Tang says.

“For true basophil activation, you need the blood to be fresh, which is challenging when you have to send it to a lab,” Dr. Tang says. “Being able to do this kind of test within a clinic or an in-house lab would be a big step forward.”
 

Next steps

While this represents a breakthrough in basophil activation testing, more research is needed to fully develop the system for clinical use. It must be standardized, automated, and miniaturized, the researchers say.

That said, the results give hope to those with food allergies that tomorrow’s gold-standard test will require only a blood sample without an emergency team standing by.

What would you do if you believed you had a serious health issue, but the best way to find out for sure might kill you?

That’s the reality for patients who wish to confirm or rule out a food allergy, says Sindy Tang, PhD, an associate professor of mechanical engineering at Stanford (Calif.) University.

And it’s the reason Dr. Tang and her colleagues are developing a food allergy test that’s not only safer, but also more reliable than today’s tests. In a paper in the journal Lab on a Chip, Dr. Tang and her colleagues outline the basis for this future test, which isolates a food allergy marker from the blood using a magnetic field.
 

How today’s food allergy tests fall short

The gold standard for food allergy diagnosis is something called the oral food challenge. That’s when the patient eats gradually increasing amounts of a problem food – say, peanuts – every 15 to 30 minutes to see if symptoms occur. This means highly allergic patients may risk anaphylaxis, an allergic reaction that causes inflammation so severe that breathing becomes restricted and blood pressure drops. Because of that, a clinical team must be at the ready with treatments like oxygen, epinephrine, or albuterol.

“The test is very accurate, but it’s also potentially unsafe and even fatal in rare cases,” Dr. Tang says. “That’s led to many sham tests advertised online that claim to use hair samples for food tests, but those are inaccurate and potentially dangerous, since they may give someone a false sense of confidence about a food they should avoid.”

Heat waves are getting hotter and becoming more frequent because of rising rates of air pollution, putting children’s health at risk, a wide-ranging new report finds.

An article in the New England Journal of Medicine reviews current research to take a sweeping inventory of how air pollution and climate change interact to adversely affect people’s health, especially that of kids. It examined the link between fossil fuel emissions and a variety of consequences of climate change – including extreme weather events; wildfires; vector-borne illnesses such as malaria, Zika, and Lyme disease; and heat waves, a topic at the forefront of many people’s minds.

This month, for example, record-high temperatures have been reported across the United States, affecting more than 100 million people and touching locations from the Gulf Coast to the Great Lakes, the Southwest, the mid-Atlantic, and the Midwest.

In Texas, Austin has already experienced an 8-day streak of temperatures above the 100° F mark in June, according to the Austin American-Statesman.

These patterns are an important reality to note, said Frederica Perera, DrPH, PhD, the article’s lead author. “My concern is that the threats are rising as temperature is rising,” Dr. Perera, a professor at Columbia University’s Mailman School of Public Health, New York, told KHN. “Temperatures are rising because greenhouse gas emissions are rising, and that’s a great concern for everyone’s health – but especially the most vulnerable.”

Children fit into this category, wrote Dr. Perera and her coauthor, Kari Nadeau, MD, PhD, Naddisy Foundation Endowed Professor of Medicine and Pediatrics at Stanford (Calif.) University, because their ability to regulate temperature, known as thermoregulation, is not fully developed.

They are also more susceptible to heat-related stress because they’re smaller and need to drink and eat more frequently to stay healthy, said Dr. Perera. But because “young children are dependent on parents to provide, sometimes their needs go ignored,” she said.

The authors noted that heat-related illness is “a leading and increasing cause of death and illness among student athletes” in the United States. In addition, they cited studies suggesting that “the heat associated with climate change” takes a toll on the mental health of children and adolescents, as well as their ability to learn.

The review article pointed to previous research. that associated in utero exposure to heat waves with “increased risks of preterm birth or low birth weight; hyperthermia and death among infants; and heat stress, kidney disease, and other illnesses” among kids.

“Being pregnant is very physiologically demanding in itself, and then heat places additional stress on a pregnant woman,” said Dr. Robert Dubrow, a professor of epidemiology at Yale’s School of Public Health, New Haven, Conn., who was not associated with either study. “And the fetus can experience heat stress as well, which could result in adverse birth outcomes.”

And these heat-related risks are across-the-board greater for “low-income communities and communities of color,” wrote the authors of the new article.

Carbon dioxide emissions from burning fossil fuels have risen sharply in the past 70 years, according to the article. “Modeling indicates that some heat waves would be extraordinarily unlikely to occur in the absence of climate change,” it says.

The authors briefly outline solutions that they describe as “climate and environmental strategies” that “should also be seen as essential public health policy.” Beyond big-picture efforts to mitigate fossil fuel and greenhouse gas emissions, they offered various ways to protect children – steps they term “adaptation measures” – which included providing clean water to children and families facing drought or water contamination and creating shaded areas where children play, live, and go to school.

Separately, Austin-based research highlighted why this step could be meaningful.

Researchers tracked the physical activity levels and location of students ages 8 to 10 during recess at three elementary schools in 2019. They compared children’s activity at recess during two weeks in September, the hottest full month during the school year, to a cooler week in November. “We wanted to understand the impact of outdoor temperatures on children’s play in schoolyard environments,” said Dr. Kevin Lanza, the study’s lead investigator, to inform the design of “future school-based interventions for physical activity in the face of climate change.”

During the hotter periods, he said, “children engaged in less physical activity and sought shade.”

As temperatures continue to rise, he said, schools must be flexible in making sure students are getting the daily exercise they need. “Schools should consider adding shade, either by planting trees or installing artificial structures that cover spaces intended for physical activity,” said Dr. Lanza, an assistant professor at UTHealth School of Public Health, Austin, Tex. He also noted that school policies could be updated so that recesses are scheduled during cooler times of the day and moved inside during periods of extreme heat.

But the overall need to protect kids from scorching weather patterns requires action beyond such steps, Dr. Perera said, and more climate and clean air policies must be enacted.

“Governments have the responsibility to protect the population and especially those most vulnerable, which especially includes children,” Dr. Perera said. “Action must be done immediately because we’re absolutely heading in the wrong direction.”

Erythema annulare centrifugum

A thorough body examination failed to reveal any other rashes or lesions suggestive of a fungal infection. A blood count and urinalysis were within normal limits. She had no lymphadenopathy or hepatosplenomegaly. A potassium hydroxide analysis of skin scrapings was negative for fungal elements. Punch biopsy of the skin on the left arm revealed focal intermittent parakeratosis, mildly acanthotic and spongiotic epidermis, and a tight superficial perivascular chronic dermatitis consisting of lymphocytes and histiocytes (Figures). Given these findings, a diagnosis of erythema annulare centrifugum (EAC) was rendered.

EAC is a rare, reactive skin rash characterized by redness (erythema) and ring-shaped lesions (annulare) that slowly spread from the center (centrifugum). The lesions present with a characteristic trailing scale on the inner border of the erythematous ring. Lesions may be asymptomatic or mildly pruritic and commonly involve the trunk, buttocks, hips, and upper legs. It is important to note that its duration is highly variable, ranging from weeks to decades, with most cases persisting for 9 months. EAC typically affects young or middle-aged adults but can occur at any age.

Erythema marginatum is a rare skin rash commonly seen with acute rheumatic fever secondary to streptococcal infection. It presents as annular erythematous lesions on the trunk and proximal extremities that are exacerbated by heat. It is often associated with active carditis related to rheumatic fever. This self-limited rash usually resolves in 2-3 days. Our patient was asymptomatic without involvement of other organs.

Like EAC, granuloma annulare is a benign chronic skin condition that presents with ring-shaped lesions. Its etiology is unknown, and lesions may be asymptomatic or mildly pruritic. Localized granuloma annulare typically presents as reddish-brown papules or plaques on the fingers, hands, elbows, dorsal feet, or ankles. The distinguishing feature of granuloma annulare from other annular lesions is its absence of scale.

Urticaria multiforme is an allergic hypersensitivity reaction commonly linked to viral infections, medications, and immunizations. Clinical features include blanchable annular/polycyclic lesions with a central purplish or dusky hue. Diagnostic pearls include the presence of pruritus, dermatographism, and individual lesions that resolve within 24 hours, all of which were not found in our patient’s case.

There may be a link between the recent unexplained cases of hepatitis in children and prior coronavirus infections, according to new research from Israel.

The study involves five children in Israel who had mild cases of COVID-19 who went on to develop hepatitis; two of these children required liver transplants. But clinicians are cautious about drawing conclusions from such a small study.

“All you can say is that these five cases seem to have proximity to COVID-19, and COVID-19 may be able to cause pediatric liver complications,” said Nancy Reau, MD, section chief of hepatology at Rush University in Chicago. She was not involved with the study.

While COVID-19 could be one explanation for these hepatitis cases, it is also possible that the two are unrelated, said William Balistreri, MD, director emeritus of the Pediatric Liver Care Center at Cincinnati Children’s Hospital Medical Center. He also is unaffiliated with the study.

Hepatitis is rare in children, and between 30% and 50% of these pediatric cases have no known cause, according to the CDC.

Since April 2022, children with hepatitis of an unexplained cause have garnered global attention. The United Kingdom now has 240 confirmed cases, the United States is investigating 290 cases, and Israel has reported 12 cases to the World Health Organization. Many investigators think that these liver problems could be related to adenovirus – a common infection in children that normally causes cold or flu-like symptoms – because more than half of global cases tested for the virus have been positive, according to the WHO. About 12% of children with unexplained hepatitis have tested positive for SARS-CoV-2, the virus that causes COVID-19, but investigators are considering the possibility that some cases may be related to prior infections.

The study documents five patients, 3-months to 13 years old, with prior  coronavirus infection who later developed hepatitis. All were treated at Schneider Children’s Medical Hospital in Petah Tikva, Israel, during 2021. The paper was published in the Journal of Pediatric Gastroenterology and Nutrition. Two patients, a 3-month-old and 5-month-old, needed liver transplants. The other three patients (two 8-year-olds and a 13-year-old) were treated with steroids. None of the five children had received any vaccinations against COVID-19. The time between COVID-19 infection and liver problems ranged from 21 to 130 days.

“It took time to be convinced that this could be COVID-related,” said senior study author Orith Waisbourd-Zinman, MD, director of pediatric liver disease service at Schneider Children’s Medical Hospital. “It’s something that wasn’t described.”

Sudden-onset hepatitis after COVID-19 has been recorded in adults, and the virus has been associated with multisystem inflammatory syndrome in children (MIS-C). The condition causes inflammation through the body, including the heart, lungs, and kidneys.

“We know that COVID can be mischievous, and children are no more exempt from that than adults,” Dr. Reau said.

Liver samples taken from these five patients did not test positive for COVID-19, similar to how liver samples have tested negative for adenovirus in more recent hepatitis cases around the world. Dr. Waisbourd-Zinman suggested that in these patients, hepatitis may have been brought on by an inflammatory response that was triggered by the virus. 

Still, there are notable differences between these five cases and current cases internationally. These five children became sick during the period of December 2020 to September 2021, whereas all current counted cases in the United Kingdom occurred after January 2022. The first cases in the United States took place in October 2021. It could be that there were similar hepatitis cases before that were not identified, Dr. Reau said.

The ages of the Israeli children with hepatitis also differ from the cases seen globally. More than three-fourths of these reported hepatitis cases occurred in children under 5, the WHO reports, though affected individuals have been as young as 1-month-old up to 16 years old. In the United Kingdom, which accounts for about a third of cases reported to the WHO, most children with unexplained hepatitis have been between 3 and 5 years old.

More research is needed to tease out any relationship between prior COVID-19 infection and liver inflammation, Dr. Balistreri said.

“I’m not sure what to make of any of it yet. We know that SARS-CoV-2 can alter immune responses ... so it wouldn’t surprise me,” if COVID-19 and these hepatitis cases were linked, he said. “It’s just that we need more information.”

There may be a link between the recent unexplained cases of hepatitis in children and prior coronavirus infections, according to new research from Israel.

The study involves five children in Israel who had mild cases of COVID-19 who went on to develop hepatitis; two of these children required liver transplants. But clinicians are cautious about drawing conclusions from such a small study.

“All you can say is that these five cases seem to have proximity to COVID-19, and COVID-19 may be able to cause pediatric liver complications,” said Nancy Reau, MD, section chief of hepatology at Rush University in Chicago. She was not involved with the study.

While COVID-19 could be one explanation for these hepatitis cases, it is also possible that the two are unrelated, said William Balistreri, MD, director emeritus of the Pediatric Liver Care Center at Cincinnati Children’s Hospital Medical Center. He also is unaffiliated with the study.

Hepatitis is rare in children, and between 30% and 50% of these pediatric cases have no known cause, according to the CDC.

Since April 2022, children with hepatitis of an unexplained cause have garnered global attention. The United Kingdom now has 240 confirmed cases, the United States is investigating 290 cases, and Israel has reported 12 cases to the World Health Organization. Many investigators think that these liver problems could be related to adenovirus – a common infection in children that normally causes cold or flu-like symptoms – because more than half of global cases tested for the virus have been positive, according to the WHO. About 12% of children with unexplained hepatitis have tested positive for SARS-CoV-2, the virus that causes COVID-19, but investigators are considering the possibility that some cases may be related to prior infections.

The study documents five patients, 3-months to 13 years old, with prior  coronavirus infection who later developed hepatitis. All were treated at Schneider Children’s Medical Hospital in Petah Tikva, Israel, during 2021. The paper was published in the Journal of Pediatric Gastroenterology and Nutrition. Two patients, a 3-month-old and 5-month-old, needed liver transplants. The other three patients (two 8-year-olds and a 13-year-old) were treated with steroids. None of the five children had received any vaccinations against COVID-19. The time between COVID-19 infection and liver problems ranged from 21 to 130 days.
