TOPLINE:

Fetuses exposed in utero to SARS-CoV-2 are not at an increased risk for neurodevelopmental problems in early childhood.

METHODOLOGY:

• This prospective study aimed to assess whether in utero exposure to SARS-CoV-2, which causes COVID-19, is associated with abnormal neurodevelopment among children at ages 12, 18, and 24 months.
• It included 2003 pregnant individuals (mean age, 33.3 years) from the ASPIRE cohort who were enrolled before 10 weeks’ gestation and followed through 24 months post partum; 10.8% of them were exposed to SARS-CoV-2 during pregnancy, as determined via self-reported data or dried blood spot cards.
• The birth mothers were required to complete the Ages & Stages Questionnaires, Third Edition (ASQ-3), a validated screening tool for neurodevelopmental delays, at 12, 18, and 24 months postpartum.
• Neurodevelopmental outcomes were available for 1757, 1522, and 1523 children at ages 12, 18, and 24 months, respectively.
• The primary outcome was a score below the cutoff on the ASQ-3 across any of the following developmental domains: Communication, gross motor, fine motor, problem-solving, and social skills.

TAKEAWAY:

• The prevalence of abnormal ASQ-3 scores did not differ between children who were exposed to SARS-CoV-2 in utero and those who were not, at ages 12 (P = .39), 18 (P = .58), and 24 (P = .45) months.
• No association was observed between in utero exposure to SARS-CoV-2 and abnormal ASQ-3 scores among children in any of the age groups.
• The lack of an association between exposure to SARS-CoV-2 during pregnancy and abnormal neurodevelopment remained unchanged even when factors such as preterm delivery and the sex of the infant were considered.
• Supplemental analyses found no difference in risk based on the trimester of infection, presence of fever, or incidence of breakthrough infection following vaccination.

IN PRACTICE:

“In this prospective cohort study of pregnant individuals and offspring, in utero exposure to maternal SARS-CoV-2 infection was not associated with abnormal neurodevelopmental screening scores of children through age 24 months. These findings are critical considering the novelty of the SARS-CoV-2 virus to the human species, the global scale of the initial COVID-19 outbreak, the now-endemic nature of the virus indicating ongoing relevance for pregnant individuals,” the authors of the study wrote. 

“While the scientific consensus resists a link between in utero COVID-19 exposure and impaired offspring neurodevelopment, the question remains whether societal responses to the pandemic impacted developmental trajectories,” the researchers added. “Certain studies comparing infants from a pandemic cohort with historic controls have raised concerns about lower ASQ-3 scores among children living during the pandemic. Critically, socioeconomic factors influence vulnerability, not only to infection itself but also regarding the ability to deploy resources in times of stress (eg, school closures) to mitigate sources of developmental harm. Our data support this theory, with the observed independent protective association of increasing household income with childhood ASQ-3 scores. Additional research is warranted to clarify the potential impact of societal measures on early development and the differential impact of these measures on different communities.”

The study was led by Eleni G. Jaswa, MD, MSc, of the Department of Obstetrics, Gynecology & Reproductive Sciences at the University of California, San Francisco. It was published online in JAMA Network Open.

LIMITATIONS: 

Limitations of the research included the use of self-reported data and dried blood spot cards for determining exposure to SARS-CoV-2, which may have led to misclassification. The ASQ-3 is a modestly sensitive tool for detecting developmental delays that may have affected the study’s power to detect associations. The sample size of this study, while larger than many, may still have been underpowered to detect small differences in neurodevelopmental outcomes.

DISCLOSURES:

The ASPIRE cohort was supported by research grants provided to the University of California, San Francisco, and by the Start Small Foundation, the California Breast Cancer Research Program, the COVID Catalyst Award, and other sources. Some authors reported receiving grants, royalties, and personal fees, serving on medical advisory boards, and having other ties with several institutions.

More evidence suggests there is little risk in administering the live rotavirus vaccine to the babies of mothers on biologics during pregnancy for inflammatory bowel disease (IBD).

No adverse events or impairment of the immune system emerged in babies at 7 days, 1 month, and 9 months post vaccination, in findings from a small Canadian study published in Clinical Gastroenterology and Hepatology.

University of Calgary

The study found normal extended immune function testing in infants despite third-trimester maternal biologic therapy and regardless of circulating drug levels. The data provide reassurance about live rotavirus vaccination in this population and may also offer insights into the safety of other live vaccines in biologic-exposed individuals, wrote investigators led by gastroenterologist Cynthia H. Seow, MD, a professor in the Cumming School of Medicine at the University of Calgary in Alberta, Canada.

“Despite the well-established safety and effectiveness of non–live vaccination in individuals with IBD, including those on immunomodulators and biologic therapy, vaccine uptake in pregnant women with IBD and their infants remains suboptimal,” Seow said in an interview. This largely arises from maternal and physician concerns regarding transplacental transfer of IBD therapies and their impact on the safety of vaccination.

“These concerns were heightened after reports emerged of five fatal outcomes following the administration of the live Bacille Calmette-Guérin [BCG] vaccine in biologic-exposed infants. However, it had already been reported that inadvertent administration of the live oral rotavirus vaccine, a very different vaccine in terms of target and mechanism of action, in biologic-exposed individuals had not been associated with significant adverse effects,” she said.

They undertook their analysis with the hypothesis that vaccination would carry low risk, although the live oral vaccine is not currently recommended in biologic-exposed infants. “Yet rotavirus is a leading cause of severe, dehydrating diarrhea in children under the age of 5 years globally, and vaccination has led to significant reductions in hospitalizations and mortality,” Seow added.

Provision of the vaccine to anti–tumor necrosis factor (TNF)–exposed infants has been incorporated into the Canadian Public Health and Immunization guidelines, as the majority of the biologic-exposed infants were exposed to anti-TNF agents. “And with collection of further data, we expect that this will be extended to other biologic agent exposure. These data are important to pregnant women with IBD as they help to normalize their care. Pregnancy is difficult enough without having to remember exceptions to care,” Seow said.

“Before some of the studies came out, broad guidelines recommended that live vaccines should not be used in biologic-exposed infants, but this had been thought to be overly zealous and too conservative, and the risk was thought to be low,” said Elizabeth Spencer, MD, an assistant professor of pediatrics in the Division of Pediatric Gastroenterology at the Icahn School of Medicine at Mount Sinai in New York City, in an interview. Spencer was not involved in the Canadian study.

“At our center, we had some moms on biologics during pregnancy who forgot and had their babies vaccinated for rotavirus, and the babies were all fine,” she said.

The safety of this vaccine has been confirmed by several small studies and recently the PIANO Helmsley Global Consensus on Pregnancy and Inflammatory Bowel Disease, which was presented at Digestive Disease Week 2024. The consensus encompasses preconception counseling and the safety of IBD medications during pregnancy and lactation.

“Another concern, however, was that giving a live GI bug like rotavirus to babies might overstimulate their immune systems and provoke IBD,” Spencer added. “While a number of population-based studies in the US and Europe showed that was not the case, at least in the general population, there was a suggestion that, down the road, vaccination might be mildly protective against IBD in some cases.”

She added the caveat that these studies were not done in mothers and their babies with IBD, who might be inherently at greater risk for IBD. “So, a question for future research would be, ‘Is immune stimulation of the gut in IBD moms and their babies a good or a bad thing for their gut?’ ”

Spencer conceded that “the data present a bit of a blurry picture, but I think it’s always better just to vaccinate according to the regular schedule. The current data say there is no added risk, but it would be nice to look specifically at risk in moms with IBD and their children.”
 

The Study

The prospective cohort study is a substudy of a larger 2023 one that included biologic use in a range of maternal illnesses, not just IBD.

For the current study, Seow and colleagues identified 57 infants born to 52 mothers with IBD attending a pregnancy clinic at the University of Calgary in the period 2019-2023. Almost 81% of the mothers had Crohn’s disease, and the median duration of IBD was 10 years. The median gestational age at delivery was 39 weeks, and almost 60% of deliveries were vaginal. The infants had been exposed in utero to infliximab (n = 21), adalimumab (n = 19), vedolizumab (n = 10), and ustekinumab (n = 7) in the third trimester.

The 57 biologic-exposed infants underwent standardized clinical assessments, drug concentration, and immune function testing. The live oral rotavirus vaccine series was provided to 50 infants, with the first dose at a median of 13 weeks of age. Immunologic assessments validated for age were normal in all infants despite median infliximab concentrations of 6.1 μg/mL (range, 0.4-28.8 μg/mL), adalimumab concentrations of 1.7 μg/mL (range, 0.7-7.9 μg/mL), ustekinumab concentrations of 0.6 μg/mL (range, 0-1.1), and undetectable for vedolizumab at 10.7 weeks of age.

As anticipated, infant immune function was normal regardless of circulating drug levels.

The overall message, said Seow, is “healthy mum equals healthy baby. Be more concerned regarding active inflammation than active medications. In almost all circumstances, treat to target in pregnancy as you would in the nonpregnant state.” She added, however, that further studies are needed to determine the safety and optimal timing of other live vaccines, such as the BCG, in the presence of biologic therapy.

This study was funded by the Alberta Children’s Hospital Research Institute. Seow reported advisory/speaker’s fees for Janssen, AbbVie, Takeda, Pfizer, Fresenius Kabi, Bristol-Myers Squibb, Pharmascience, and Lilly, as well as funding from Alberta Children’s Hospital Research Institute, Crohn’s and Colitis Canada, the Canadian Institutes of Health Research, and Calgary Health Trust, and data safety monitoring from New South Wales Government Health, Australia. Multiple coauthors disclosed similar consulting or speaker relationships with private industry. Spencer had no competing interests with regard to her comments.

The rate of congenital heart defects is higher in newborns conceived using assisted reproductive technologies (ART) than in newborns conceived without assistance. This finding comes from a population-based cohort study led by Dr. Nona Sargisian, a gynecologist at the University of Gothenburg, Sweden, and colleagues, which was published in the European Heart Journal.

The researchers analyzed more than 7 million results of all live-born children in Denmark, Finland, Sweden, and Norway between 1984 and 2015. They found that congenital heart defects occurred more frequently in the ART newborn group (1.85%) than in naturally conceived newborns (1.15%).

The study also revealed that the risk for congenital heart defects in multiple births is higher than in single births, with and without the use of ART. However, the result that congenital heart defects occur more often in ART newborns remained significant when comparing single births from both groups (1.62% vs 1.11%).
 

Relatively Low Prevalence

Barbara Sonntag, MD, PhD, a gynecologist at Amedes Fertility Center in Hamburg, Germany, referred to a “clinically relevant risk increase” with a relatively low prevalence of the condition.

“When 1000 children are born, an abnormality occurs in 18 children after ART, compared with 11 children born after natural conception,” she told the Science Media Center.

Dr. Sonntag emphasized that the risk is particularly increased by a multiple pregnancy. A statement about causality is not possible based on the study, but multiple pregnancies are generally associated with increased risks during pregnancy and for the children.

The large and robust dataset confirms long-known findings, said Georg Griesinger, MD, PhD, medical director of the fertility centers of the University Medical Center Schleswig-Holstein in Lübeck and Manhagen, Germany.

The key figures can be found in single births, he explained. “Among single births conceived by ART, the rate of severe congenital heart defects was 1.62% compared with 1.11% in spontaneously conceived single births, an increase in risk by 1.19 times. For severe heart defects, the rate was 0.31% in ART single births, compared with 0.25% in spontaneously conceived single births.”

The increased risks are consistent with existing literature. Therefore, the current study does not reveal any new risk signals, said Dr. Griesinger.
 

Single Embryo Transfer

The “risks are small but present,” according to Michael von Wolff, MD, head of gynecological endocrinology and reproductive medicine at Bern University Hospital in Switzerland. “Therefore, ART therapy should only be carried out after exhausting conservative treatments,” he recommended. For example, ovarian stimulation with low-dose hormone preparations could be an option.

Dr. Griesinger pointed out that, in absolute numbers, all maternal and fetal or neonatal risks are significantly increased in twins and higher-order multiples, compared with the estimated risk association within the actual ART treatment.

“For this reason, reproductive medicine specialists have been advocating for single-embryo transfer for years to promote the occurrence of single pregnancies through ART,” said Dr. Griesinger.

The study “emphasizes the importance of single embryo transfer to avoid the higher risks associated with multiple pregnancies,” according to Rocío Núñez Calonge, PhD, scientific director of the International Reproduction Unit in Alicante, Spain.

Dr. Sonntag also sees a “strong additional call to avoid multiple pregnancies through a predominant strategy of single-embryo transfer in the data. The increased rate of childhood birth defects is already part of the information provided before assisted reproduction.”

The rate of congenital heart defects is higher in newborns conceived using assisted reproductive technologies (ART) than in newborns conceived without assistance. This finding comes from a population-based cohort study led by Dr. Nona Sargisian, a gynecologist at the University of Gothenburg, Sweden, and colleagues, which was published in the European Heart Journal.

The researchers analyzed more than 7 million results of all live-born children in Denmark, Finland, Sweden, and Norway between 1984 and 2015. They found that congenital heart defects occurred more frequently in the ART newborn group (1.85%) than in naturally conceived newborns (1.15%).

The study also revealed that the risk for congenital heart defects in multiple births is higher than in single births, with and without the use of ART. However, the result that congenital heart defects occur more often in ART newborns remained significant when comparing single births from both groups (1.62% vs 1.11%).
 

Relatively Low Prevalence

Barbara Sonntag, MD, PhD, a gynecologist at Amedes Fertility Center in Hamburg, Germany, referred to a “clinically relevant risk increase” with a relatively low prevalence of the condition.

“When 1000 children are born, an abnormality occurs in 18 children after ART, compared with 11 children born after natural conception,” she told the Science Media Center.

TOPLINE:

Newborns who go on to develop atopic dermatitis (AD) show higher transepidermal water loss (TEWL) and cord blood serum levels of CCL17/thymus- and activation-regulated chemokine (TARC) and interleukin (IL) 31.

METHODOLOGY:

• Researchers conducted a prospective study to evaluate the predictive role of serologic biomarkers and cutaneous markers and the development of AD in 40 full-term newborns from a university hospital in Italy.
• Cord blood was collected at birth and analyzed for serum biomarkers such as CCL17/TARC and IL-31.
• TEWL and skin hydration rates were measured at 1, 6, and 12 months, and dermatological features such as dryness, cradle cap, and eczematous lesions were also monitored during visits.

TAKEAWAY:

• At 6 months, 16 infants had symptoms of AD, which included dry skin, pruritus, and keratosis pilaris, which persisted at 12 months. Their mean Eczema Area and Severity Index score was 6.6 at 6 months and 2.9 at 12 months.
• Infants with signs of AD had significantly higher TEWL levels at the anterior cubital fossa at 1, 6, and 12 months than those without AD.
• Cord blood levels of CCL17/TARC and IL-31 were significantly higher in infants with AD.
• A correlation was found between TEWL values and CCL17 levels at 1, 6, and 12 months.

IN PRACTICE:

“This study highlights the potential of cord serum/TARC and IL-31 levels as predictive markers for AD onset in infancy, in combination with cutaneous markers,” the authors wrote. “Stratified interventions based on these variables, family history, FLG [filaggrin] variations, and other biomarkers could offer more targeted approaches to AD prevention and management, especially during the first year of life,” they added.

SOURCE:

The study was led by Angelo Massimiliano D’Erme, MD, PhD, of the Dermatology Unit, in the Department of Medical and Oncology, University of Pisa, Pisa, Italy, and was published online in JAMA Dermatology.

LIMITATIONS:

The limitations included the observational design and small sample size, and it was a single-center study.

DISCLOSURES:

The authors did not disclose any funding information. One author disclosed receiving personal fees from various pharmaceutical companies and serving as a founder and chairman of a nonprofit organization.

Information readily available on a newborn screening, combined with clinical risk factors, may eventually be able to help identify infants at increased risk for sudden infant death syndrome (SIDS), new data suggest.

Findings of the study by Scott P. Oltman, MS, of the Department of Epidemiology & Biostatistics, University of California, San Francisco, and colleagues were published in JAMA Pediatrics.

The case-controlled study showed a link between aberrant metabolic analytes at birth and SIDS. Researchers used data from the California Office of Statewide Health Planning and Development and the California Department of Public Health and included 2.3 million infants born between 2005 and 2011 in the dataset.

Of the 2.3 million infants, 354 had SIDS. The researchers found that 14 newborn screening metabolites were significantly associated with SIDS. After the screens, the babies who had elevated metabolite markers, compared with the control babies had 14.4 times higher odds of having SIDS, the researchers reported.

“It’s really promising research,” Joanna J. Parga-Belinkie, MD, an attending neonatologist who was not involved in the study, said in an interview. She practices in the Division of Neonatology at Children’s Hospital of Philadelphia in Pennsylvania. “It doesn’t really give us the answer to what causes SIDS, but I think in the long term it’s going to inform a lot of research that will help us understand whether there are biomarkers that can predict SIDS.”

Other studies have looked at different metabolic markers to see if they can help predict SIDS, she said, but the innovation in this study is that it uses newborn screens, which are collected on all babies born in a hospital. Dr. Parga-Belinkie added that another strength of the study is its large sample size and matched controls to compare the SIDS cases with healthy babies.

“That said, newborn screens are a screening test, they are not diagnostic,” Dr. Parga-Belinkie said. “We definitely need further testing to see if (the metabolic biomarkers) really make that link to SIDS.”

It will be important to test this in a prospective study over time and in real time, she said, which is something the authors acknowledge. They list the retrospective design of the study as a major limitation.

These study results won’t change the counseling for families on decreasing risk, Dr. Parga-Belinkie said, “because there’s not a clear biomarker that has emerged and we don’t have a clear link yet.” Safe sleep hygiene will continue to be the primary focus of counseling parents, such as placing the baby on its back on a firm, flat surface with no loose bedding or stuffed animals.

The study authors said several things will need to be clarified with future research, noting that a majority of the infants in the California database were of Hispanic ethnicity. Testing other populations will help determine generalizability.

Also, there has been ambiguity in the definition of SIDS, which has led to inconsistencies in classifying a death as SIDS or death from an unknown cause of suffocation or asphyxiation.

They added: “It may also be the case that these markers are predictive and reliable but not causal in nature and distinguishing between the two is a crucial topic for future investigation.”

This work was supported in part by the California Preterm Birth Initiative within the University of California, San Francisco, and by the National Institutes of Health. Mr. Oltman reported having a patent pending for a newborn metabolic vulnerability model for identifying preterm infants at risk of adverse outcomes and uses thereof. One coauthor reported having a patent pending and a patent issued; another reported having a patent pending for a newborn metabolic vulnerability model for identifying preterm infants at risk of adverse outcomes and uses thereof. Dr. Parga-Belinkie declared no relevant financial disclosures.

Higher prenatal exposure to the chemical bisphenol A (BPA) is associated with a greater risk for autism spectrum disorder (ASD) in men, potentially via the disruption of a key enzyme in the developing brain.

BPA is a potent endocrine disruptor found in polycarbonate plastics and epoxy resins and has been banned by the Food and Drug Administration for use in baby bottles, sippy cups, and infant formula packaging.

“Exposure to BPA has already been shown in some studies to be associated with subsequent autism in offspring,” lead researcher Anne-Louise Ponsonby, PhD, The Florey Institute, Heidelberg, Australia, said in a statement.

“Our work is important because it demonstrates one of the biological mechanisms potentially involved. BPA can disrupt hormone-controlled male fetal brain development in several ways, including silencing a key enzyme, aromatase, that controls neurohormones and is especially important in fetal male brain development. This appears to be part of the autism puzzle,” she said.

Brain aromatase, encoded by CYP19A1, converts neural androgens to neural estrogens and has been implicated in ASD. Postmortem analyses of men with ASD also show markedly reduced aromatase activity.

The findings were published online in Nature Communications.
 

New Biological Mechanism

For the study, the researchers analyzed data from the Barwon Infant Study in 1067 infants in Australia. At age 7-11 years, 43 children had a confirmed ASD diagnosis, and 249 infants with Child Behavior Checklist (CBCL) data at age 2 years had an autism spectrum problem score above the median.

The researchers developed a CYP19A1 genetic score for aromatase activity based on five single nucleotide polymorphisms associated with lower estrogen levels. Among 595 children with prenatal BPA and CBCL, those with three or more variants were classified as “low aromatase activity” and the remaining were classified as “high.”

In regression analyses, boys with low aromatase activity and high prenatal BPA exposure (top quartile > 2.18 µg/L) were 3.5 times more likely to have autism symptoms at age 2 years (odds ratio [OR], 3.56; 95% CI, 1.13-11.22).

The odds of a confirmed ASD diagnosis were six times higher at age 9 years only in men with low aromatase activity (OR, 6.24; 95% CI, 1.02-38.26).

The researchers also found that higher BPA levels predicted higher methylation in cord blood across the CYP19A1 brain promoter PI.f region (P = .009).

To replicate the findings, data were used from the Columbia Centre for Children’s Health Study–Mothers and Newborns cohort in the United States. Once again, the BPA level was associated with hypermethylation of the aromatase brain promoter PI.f (P = .0089).

In both cohorts, there was evidence that the effect of increased BPA on brain-derived neurotrophic factor hypermethylation was mediated partly through higher aromatase gene methylation (P = .001). 

To validate the findings, the researchers examined human neuroblastoma SH-SY5Y cell lines and found aromatase protein levels were more than halved in the presence of BPA 50 µg/L (P = .01).

Additionally, mouse studies showed that male mice exposed to BPA 50 µg/L mid-gestation and male aromatase knockout mice — but not female mice — had social behavior deficits, such as interacting with a strange mouse, as well as structural and functional brain changes.

“We found that BPA suppresses the aromatase enzyme and is associated with anatomical, neurologic, and behavioral changes in the male mice that may be consistent with autism spectrum disorder,” Wah Chin Boon, PhD, co–lead researcher and research fellow, also with The Florey Institute, said in a statement.

“This is the first time a biological pathway has been identified that might help explain the connection between autism and BPA,” she said.

“In this study, not only were the levels of BPA higher than most people would be exposed to, but in at least one of the experiments the mice were injected with BPA directly, whereas humans would be exposed via food and drink,” observed Oliver Jones, PhD, MSc, professor of chemistry, RMIT University, Melbourne, Australia. “If you ingest the food, it undergoes metabolism before it gets to the bloodstream, which reduces the effective dose.”

Dr. Jones said further studies with larger numbers of participants measuring BPA throughout pregnancy and other chemicals the mother and child were exposed to are needed to be sure of any such link. “Just because there is a possible mechanism in place does not automatically mean that it is activated,” he said.

Dr. Ponsonby pointed out that BPA and other endocrine-disrupting chemicals are “almost impossible for individuals to avoid” and can enter the body through plastic food and drink packaging, home renovation fumes, and sources such as cosmetics.
 

Fatty Acid Helpful? 

Building on earlier observations that 10-hydroxy-2-decenoic acid (10HDA) may have estrogenic modulating activities, the researchers conducted additional studies suggesting that 10HDA may be effective as a competitive ligand that could counteract the effects of BPA on estrogen signaling within cells.

Further, among 3-week-old mice pups prenatally exposed to BPA, daily injections of 10HDA for 3 weeks showed striking and significant improvements in social interaction. Stopping 10HDA resulted in a deficit in social interaction that was again ameliorated by subsequent 10HDA treatment.

“10-hydroxy-2-decenoic acid shows early indications of potential in activating opposing biological pathways to improve autism-like characteristics when administered to animals that have been prenatally exposed to BPA,” Dr. Boon said. “It warrants further studies to see whether this potential treatment could be realized in humans.”

Reached for comment, Dr. Jones said “the human studies are not strong at all,” in large part because BPA levels were tested only once at 36 weeks in the BIS cohort.

“I would argue that if BPA is in the urine, it has been excreted and is no longer in the bloodstream, thus not able to affect the child,” he said. “I’d also argue that a single measurement at 36 weeks cannot give you any idea of the mother’s exposure to BPA over the rest of the pregnancy or what the child was exposed to after birth.”

The study was funded by the Minderoo Foundation, the National Health and Medical Research Council of Australia, the Australian Research Council, and numerous other sponsors. Dr. Boon is a coinventor on “Methods of treating neurodevelopmental diseases and disorders” and is a board member of Meizon Innovation Holdings. Dr. Ponsonby is a scientific adviser to Meizon Innovation Holdings. The remaining authors declared no competing interests.

This appears to be part of the autism puzzle,” she said.

Brain aromatase, encoded by CYP19A1, converts neural androgens to neural estrogens and has been implicated in ASD. Postmortem analyses of men with ASD also show markedly reduced aromatase activity.

The findings were published online in Nature Communications.
 

New Biological Mechanism

For the study, the researchers analyzed data from the Barwon Infant Study in 1067 infants in Australia. At age 7-11 years, 43 children had a confirmed ASD diagnosis, and 249 infants with Child Behavior Checklist (CBCL) data at age 2 years had an autism spectrum problem score above the median.

The researchers developed a CYP19A1 genetic score for aromatase activity based on five single nucleotide polymorphisms associated with lower estrogen levels. Among 595 children with prenatal BPA and CBCL, those with three or more variants were classified as “low aromatase activity” and the remaining were classified as “high.”

In regression analyses, boys with low aromatase activity and high prenatal BPA exposure (top quartile > 2.18 µg/L) were 3.5 times more likely to have autism symptoms at age 2 years (odds ratio [OR], 3.56; 95% CI, 1.13-11.22).

The odds of a confirmed ASD diagnosis were six times higher at age 9 years only in men with low aromatase activity (OR, 6.24; 95% CI, 1.02-38.26).

The researchers also found that higher BPA levels predicted higher methylation in cord blood across the CYP19A1 brain promoter PI.f region (P = .009).

To replicate the findings, data were used from the Columbia Centre for Children’s Health Study–Mothers and Newborns cohort in the United States. Once again, the BPA level was associated with hypermethylation of the aromatase brain promoter PI.f (P = .0089).

In both cohorts, there was evidence that the effect of increased BPA on brain-derived neurotrophic factor hypermethylation was mediated partly through higher aromatase gene methylation (P = .001). 

To validate the findings, the researchers examined human neuroblastoma SH-SY5Y cell lines and found aromatase protein levels were more than halved in the presence of BPA 50 µg/L (P = .01).

Additionally, mouse studies showed that male mice exposed to BPA 50 µg/L mid-gestation and male aromatase knockout mice — but not female mice — had social behavior deficits, such as interacting with a strange mouse, as well as structural and functional brain changes.

“We found that BPA suppresses the aromatase enzyme and is associated with anatomical, neurologic, and behavioral changes in the male mice that may be consistent with autism spectrum disorder,” Wah Chin Boon, PhD, co–lead researcher and research fellow, also with The Florey Institute, said in a statement.

“This is the first time a biological pathway has been identified that might help explain the connection between autism and BPA,” she said.

“In this study, not only were the levels of BPA higher than most people would be exposed to, but in at least one of the experiments the mice were injected with BPA directly, whereas humans would be exposed via food and drink,” observed Oliver Jones, PhD, MSc, professor of chemistry, RMIT University, Melbourne, Australia. “If you ingest the food, it undergoes metabolism before it gets to the bloodstream, which reduces the effective dose.”

Dr. Jones said further studies with larger numbers of participants measuring BPA throughout pregnancy and other chemicals the mother and child were exposed to are needed to be sure of any such link. “Just because there is a possible mechanism in place does not automatically mean that it is activated,” he said.

Dr. Ponsonby pointed out that BPA and other endocrine-disrupting chemicals are “almost impossible for individuals to avoid” and can enter the body through plastic food and drink packaging, home renovation fumes, and sources such as cosmetics.
 

Fatty Acid Helpful? 

Building on earlier observations that 10-hydroxy-2-decenoic acid (10HDA) may have estrogenic modulating activities, the researchers conducted additional studies suggesting that 10HDA may be effective as a competitive ligand that could counteract the effects of BPA on estrogen signaling within cells.

Further, among 3-week-old mice pups prenatally exposed to BPA, daily injections of 10HDA for 3 weeks showed striking and significant improvements in social interaction. Stopping 10HDA resulted in a deficit in social interaction that was again ameliorated by subsequent 10HDA treatment.

“10-hydroxy-2-decenoic acid shows early indications of potential in activating opposing biological pathways to improve autism-like characteristics when administered to animals that have been prenatally exposed to BPA,” Dr. Boon said. “It warrants further studies to see whether this potential treatment could be realized in humans.”

Reached for comment, Dr. Jones said “the human studies are not strong at all,” in large part because BPA levels were tested only once at 36 weeks in the BIS cohort.

“I would argue that if BPA is in the urine, it has been excreted and is no longer in the bloodstream, thus not able to affect the child,” he said. “I’d also argue that a single measurement at 36 weeks cannot give you any idea of the mother’s exposure to BPA over the rest of the pregnancy or what the child was exposed to after birth.”

The study was funded by the Minderoo Foundation, the National Health and Medical Research Council of Australia, the Australian Research Council, and numerous other sponsors. Dr. Boon is a coinventor on “Methods of treating neurodevelopmental diseases and disorders” and is a board member of Meizon Innovation Holdings.

Higher prenatal exposure to the chemical bisphenol A (BPA) is associated with a greater risk for autism spectrum disorder (ASD) in men, potentially via the disruption of a key enzyme in the developing brain.

BPA is a potent endocrine disruptor found in polycarbonate plastics and epoxy resins and has been banned by the Food and Drug Administration for use in baby bottles, sippy cups, and infant formula packaging.

“Exposure to BPA has already been shown in some studies to be associated with subsequent autism in offspring,” lead researcher Anne-Louise Ponsonby, PhD, The Florey Institute, Heidelberg, Australia, said in a statement.

“Our work is important because it demonstrates one of the biological mechanisms potentially involved. BPA can disrupt hormone-controlled male fetal brain development in several ways, including silencing a key enzyme, aromatase, that controls neurohormones and is especially important in fetal male brain development. This appears to be part of the autism puzzle,” she said.

Fevers? Vomiting? Fussiness? How to manage the first night home from the hospital? These are just a few of the hundreds of questions from parents that Atlanta, Georgia–based pediatric nurses Jennifer Walker and Laura Hunter answered well into the night.

A Folder, a Swaddle, and a Mission

Ms. Walker and Ms. Hunter literally wrote the book on helping people in the trenches of new parenthood. But it wasn’t quite a book at first. “It was a folder we printed off the computer with those questions coming in,” Ms. Hunter recalled. The nurses developed a way to approach each call with a specific outline of protocols they had designed.

“What if we just go to the [patient’s] house and help them figure that out?” Ms. Walker remembered one of the pediatricians she worked with suggesting in 2002. For example, Ms. Hunter’s swaddle technique that calmed even the fussiest babies worked much better if it was demonstrated in person.

The two embarked on home visits with new parents. But their advice would be practical, not medical. Because they were not classified as traveling nurses, they drew a “definitive line” that they wouldn’t be discussing “major medical issues.”

“Going into the homes here in Atlanta, taking that folder, clipping nails, doing baths, discussing feeding — whether you were doing bottles or breastfeeding — we were going to help parents where they were,” Ms. Hunter said.

The physicians they worked with began recommending their services. Ms. Walker jokes that they didn’t know what they were doing at first; they considered giving their first client their money back. But parents needed what they were delivering, which was advice, validation, and confidence in their parenting.

Just 6-8 weeks into their initiative, other practices started to inquire about whether the nurses could do the same thing for them.

It was a solution to the problem of the 15-minute office visit. “We were helping with those questions so that when [babies] came in for their well visits, those questions were already answered. Not only did we go into their homes, but we supported them in the months after we left,” Ms. Hunter said.
 

The Ripple Effect

The outcomes were astonishing. “Babies were sleeping through the night. Parents were more confident. We didn’t expect the results, and we were shocked at how consistent it was,” Ms. Walker said. “Laura and I used to call each other in disbelief after we would put these basic principles in place and partner with parents.”

Local pediatricians were grateful for the help. But for the nurses, it was about walking alongside families. The two have countless stories of desperate parents, marriages “on the brink of disaster,” moments when they realized their work was having a ripple effect.

One military family stands out in Ms. Walker’s memory. “The father was fighting for our country overseas, and his wife was struggling alone at home.”

But support from Moms on Call had a powerful impact. “When [the father] came home, he presented Laura with a flag and a beautiful personal note expressing his gratitude,” Ms. Walker said. “Once his wife had a partner to help and felt confident and well rested, his heart could rest as well. We did what he couldn’t, and it made all the difference. After all, that’s what he was fighting for in the first place.”
 

The Gambler Calls

After just 1 or 2 years as Moms on Call, Ms. Walker and Ms. Hunter got an unexpected call from none other than celebrity singer Kenny Rogers, who needed help with his twins.

“I was flipping through the folder, and he said: ‘It’s not copyrighted. It’ll be copyrighted tomorrow morning,’ ” Ms. Hunter recalled.

Mr. Rogers’ attorneys called the next day to provide all the information. “He said: ‘Y’all have got something here. Send this folder to a self-publishing company. Throw up a website. It’ll cost you a few thousand bucks,’” said Ms. Hunter. The business was officially born in 2004.

More of Mr. Rogers’ advice: “You can’t hit a bull’s-eye if you don’t throw a few darts. This is worth throwing a few darts at.”
 

‘They Don’t Teach You That in Nursing School’

The two nurses reimagined their all-knowing folder as a book with a DVD in the back. Because how do you teach parents how to suction noses without showing it? They also wanted to use an outline format — simpler for exhausted parents who just needed to get the information quickly. A few publishers pushed back on these ideas. But the nurses persisted and self-published the first edition.

The original website was basic. Ms. Walker’s Aunt Janet put it together. But grateful clients were Ms. Walker and Ms. Hunter’s best marketing tool, spreading the word to friends and family. The message: Parents know their own children best and can be empowered to help their own kids, rather than leaning on professionals alone.

A community of families also helped them navigate starting a business. A client who was a mergers and acquisitions lawyer helped them form their LLC. “They don’t teach you that in nursing school,” Ms. Walker said. 

Ms. Walker added that they made mistakes. “Not everyone that we encountered viewed or felt the same way about growing a business that is primarily focused on helping families. Sometimes that meant offering services at no charge. Or saying no to certain partnerships that didn’t align with our business model.”

Ms. Walker and Ms. Hunter had an eye on equity in creating multiple ways to access their advice at various price points. They started by charging around $75 for an in-home visit. (Now, if one of the CEOs comes out, it’s around $1000.) But the books, app, and online resources support those who can’t access that, as do an additional 10 in-home consultants around the country.

Along the way, moments told them they were going in the right direction and helped them define their purpose. “It is having a client ‘buy’ us as their go-to [baby] shower gift. It is being able to provide and support a clinic in Kenya or military families around the world. It is helping families realize that they can sleep — that they aren’t alone,” Ms. Walker said. 
 

On Call 24/7 in the Car, in the Checkout Line ...

The early days of Moms on Call were also a juggling act. As Ms. Walker and Ms. Hunter balanced work and home with 10 of their own kids between the two of them, they took calls wherever they were. A friend and caller once joked that she could tell Ms. Hunter was checking out at the grocery store while she advised her on her very sick son’s vomiting.

“We were still trying to take care of the kids, run the house, and neither one of us had nannies or night nurses or housekeepers,” Ms. Hunter said. “But being on call allowed us to still be at home.”

Ms. Walker remembers taking calls on the way to ball games with her own kids, who by 8 years old could recite the advice for a baby’s fever from the back of the car. “It was like a family affair, and our kids got to see how that works and see their moms in action,” she said.

Through it all, Ms. Walker and Ms. Hunter’s motivation came from knowing that thousands of parents were begging for help — and they had an answer.

“Our shoulders have absorbed so many tears of parents who were exhausted and hurting, some who had been lied to or told their child would never sleep or had to be raised a certain way. When someone steals that confidence, especially from a brand-new parent overwhelmed by information, it makes us want to shout the truth from every rooftop and digital channel available,” Ms. Walker added.
 

Do You Have a Business Idea?

“Boots on the ground” healthcare professionals often see new opportunities to serve patients who might be falling through the cracks of the healthcare system. While not all will become a full-blown business, Ms. Hunter encourages them to break down their idea into “bite-sized pieces.” Just have the next conversation.

“Ask the people around you and the people who are brought to you,” Ms. Hunter said. When the two nurses look back, they see how those pieces of the puzzle were meant to come together. “Ask everyone you know,” Ms. Hunter advised. “And talk to the people you are taking care of. It’s possible they have a gift that will help you get to the next bite-sized piece.”

In short — develop a network of people who believe in your idea. Prioritize those relationships and see where they can take you.

The close relationship between Ms. Walker and Ms. Hunter, as business partners and friends, has also been crucial. They joke that they finish each other’s sentences and sandwiches. “You have to fight for that — we prioritize [that relationship]” too, Ms. Walker said.

Finally, remember why you are doing what you do, Ms. Walker said. “These are the people we help: Wonderful people with jobs that serve us all — the airplane pilot, the anesthesiologist, the pediatrician, the single dad. They are all parents who have felt alone and exhausted. In those lonely moments of a parent’s heart where they fear they are doing the wrong thing, we want to be the voice of hope,” she added. “We let them know that if they ever wondered if they were doing it right, well, only good parents wonder that.”

They also wanted to use an outline format — simpler for exhausted parents who just needed to get the information quickly. A few publishers pushed back on these ideas. But the nurses persisted and self-published the first edition.

The original website was basic. Ms. Walker’s Aunt Janet put it together. But grateful clients were Ms. Walker and Ms. Hunter’s best marketing tool, spreading the word to friends and family. The message: Parents know their own children best and can be empowered to help their own kids, rather than leaning on professionals alone.

A community of families also helped them navigate starting a business. A client who was a mergers and acquisitions lawyer helped them form their LLC. “They don’t teach you that in nursing school,” Ms. Walker said. 

Ms. Walker added that they made mistakes. “Not everyone that we encountered viewed or felt the same way about growing a business that is primarily focused on helping families. Sometimes that meant offering services at no charge. Or saying no to certain partnerships that didn’t align with our business model.”

Ms. Walker and Ms. Hunter had an eye on equity in creating multiple ways to access their advice at various price points. They started by charging around $75 for an in-home visit. (Now, if one of the CEOs comes out, it’s around $1000.) But the books, app, and online resources support those who can’t access that, as do an additional 10 in-home consultants around the country.

Along the way, moments told them they were going in the right direction and helped them define their purpose. “It is having a client ‘buy’ us as their go-to [baby] shower gift. It is being able to provide and support a clinic in Kenya or military families around the world. It is helping families realize that they can sleep — that they aren’t alone,” Ms. Walker said. 
 

On Call 24/7 in the Car, in the Checkout Line ...

The early days of Moms on Call were also a juggling act. As Ms. Walker and Ms. Hunter balanced work and home with 10 of their own kids between the two of them, they took calls wherever they were. A friend and caller once joked that she could tell Ms. Hunter was checking out at the grocery store while she advised her on her very sick son’s vomiting.

“We were still trying to take care of the kids, run the house, and neither one of us had nannies or night nurses or housekeepers,” Ms. Hunter said. “But being on call allowed us to still be at home.”

Ms. Walker remembers taking calls on the way to ball games with her own kids, who by 8 years old could recite the advice for a baby’s fever from the back of the car. “It was like a family affair, and our kids got to see how that works and see their moms in action,” she said.

Through it all, Ms. Walker and Ms. Hunter’s motivation came from knowing that thousands of parents were begging for help — and they had an answer.

“Our shoulders have absorbed so many tears of parents who were exhausted and hurting, some who had been lied to or told their child would never sleep or had to be raised a certain way. When someone steals that confidence, especially from a brand-new parent overwhelmed by information, it makes us want to shout the truth from every rooftop and digital channel available,” Ms. Walker added.
 

Do You Have a Business Idea?

“Boots on the ground” healthcare professionals often see new opportunities to serve patients who might be falling through the cracks of the healthcare system. While not all will become a full-blown business, Ms. Hunter encourages them to break down their idea into “bite-sized pieces.” Just have the next conversation.

“Ask the people around you and the people who are brought to you,” Ms. Hunter said. When the two nurses look back, they see how those pieces of the puzzle were meant to come together. “Ask everyone you know,” Ms. Hunter advised. “And talk to the people you are taking care of. It’s possible they have a gift that will help you get to the next bite-sized piece.”

In short — develop a network of people who believe in your idea. Prioritize those relationships and see where they can take you.

The close relationship between Ms. Walker and Ms. Hunter, as business partners and friends, has also been crucial. They joke that they finish each other’s sentences and sandwiches. “You have to fight for that — we prioritize [that relationship]” too, Ms. Walker said.

Finally, remember why you are doing what you do, Ms. Walker said. “These are the people we help: Wonderful people with jobs that serve us all — the airplane pilot, the anesthesiologist, the pediatrician, the single dad. They are all parents who have felt alone and exhausted. In those lonely moments of a parent’s heart where they fear they are doing the wrong thing, we want to be the voice of hope,” she added. “We let them know that if they ever wondered if they were doing it right, well, only good parents wonder that.”

While there may be some lactation consultants who disagree, in my experience counseling women attempting to breastfeed is more art than science. Well before the American Academy of Pediatrics (AAP) began to offer mini courses on breastfeeding for practitioners I was left to help new mothers based on watching my wife nurse our three children and what scraps of common sense I could sweep up off the floor.

Using my own benchmarks of success I would say I did a decent job with dyads who sought my help. I began by accepting that even under optimal conditions, not every woman and/or child can successfully breastfeed. None of the infants died or was hospitalized with dehydration. A few may have required some additional phototherapy, but they all completed infancy in good shape. On the maternal side I am sure there were a few mothers who had lingering feelings of inadequacy because they had “failed” at breastfeeding. But, for the most part, I think I succeeded in helping new mothers remain as mentally healthy as they could be given the rigors of motherhood. At least I gave it my best shot.

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.

More than 5% of cases of sudden infant death may be linked to maternal obesity, new research showed.

“When a parent has a child that dies of sudden unexplained infant death [SUID], it’s extremely devastating,” said Jan-Marino Ramirez, PhD, the Zain Nadella Endowed Chair in Pediatric Neurosciences at the University of Washington, Seattle, and director of the Center for Integrative Brain Research at Seattle Children’s Hospital. “And the most devastating problem is that there’s no clear answer. Understanding the mechanisms will help parents understand.”

The study was published online in JAMA Pediatrics.

In the United States, approximately 3500 cases of SUID are reported yearly. After educational campaigns in the 1990s demonstrating safe infant sleep positions, rates of these fatalities dropped but have since plateaued.
 

Maternal Obesity During Pregnancy

Rates of maternal obesity are increasing globally, and more than half of women of reproductive age are overweight or obese.

“Maternal obesity before pregnancy affects placental development, gene expression, and has long-term implications,” said Patrick Catalano, MD, a professor in residence at the Departments of Reproductive Endocrinology and Obstetrics and Gynecology at Massachusetts General Hospital and Harvard Medical School in Boston.

Maternal obesity is a well-documented risk factor for adverse outcomes of pregnancy including stillbirth, preterm birth, and admission to the neonatal intensive care unit. Swedish researchers in 2014 reported maternal obesity was linked to an increase in infant mortality that increased with body mass index (BMI), but that study did not look specifically at SUID.

For their new study, Dr. Ramirez and colleagues looked at data from all live births in the United States from 2015 to 2019 recorded by the Centers for Disease Control and Prevention and the National Center for Health Statistics. Of the 18,857,694 live births occurring at 28 weeks of gestation or later, 16,545 infants died of a sudden, unexplained cause.

Rates of SUID in babies born to mothers with obesity increased in a statistically significant, dose-dependent manner relative to normal weight mothers. The unadjusted absolute risks for SUID were 0.74 cases per 1000 births for normal weight mothers, 0.99 cases at BMIs between 30 and 35, 1.17 cases at BMIs between 35 and 40, and 1.47 instances at BMI ≥ 40.

After adjustment for maternal age, race, ethnicity, and level of education, the adjusted odds ratio for a case of SUID was 1.39 among women with the highest levels of obesity (95% CI, 1.31-1.47), according to the researchers.

While the study revealed an association between maternal obesity and SUID, the basis for this connection remains unknown, the investigators noted. One possibility for the link is that obesity increases the risk for obstructive sleep apnea, which can result in intermittent hypoxia. That, in turn, causes oxidative stress, which may possibly have effects on the fetus causing effects that eventually lead to SUID in the infant.

An accompanying editorial by Jacqueline Maya, MD; Marie-France Hivert, MD, MMSc; and Lydia Shook, MD, from the Massachusetts General Hospital and Harvard Medical School, suggested that the SUID is unlikely directly influenced by high maternal BMI but rather by the metabolic concerns related to obesity such as inflammation, insulin resistance, and abnormal lipid metabolism. Epigenetics may also play a role.

“We believe the evidence for this study of an association between prepregnancy obesity and SUID is a call to action for the scientific and medical community to better understand the complex interplay of biological, social, and behavioral factors that may lead to SUID, a devastating complication that no family should experience,” the authors of the editorial wrote.

Dr. Ramirez stressed the importance of not initiating guilt because there are many factors in SUID such as genetics that cannot be controlled.

“We are far from saying a baby died because you were obese; that’s an important message to parents,” he said. What he sees as important, rather, is using this new research to elucidate further mechanisms that may allow for more targeted interventions: “If we discover that it’s due to, for example, sleep apnea, that’s something we can prevent.”

The researchers reported no conflicts of interest.

TORONTO — Lawrence A. Schachner, MD, would like pediatric dermatologists to adopt a “toxic agent of the year” to raise awareness about the potential harm related to certain topical treatments in babies and young children.

Dr. Schachner, director of the Division of Pediatric Dermatology in the Department of Dermatology & Cutaneous Surgery at the University of Miami, Coral Gables, Florida, said he got the idea from the American Contact Dermatitis Society, which annually names the “Allergen of the Year.”

In pediatric dermatology, the list of potentially toxic products includes topical analgesics such as Castellani paint used for skin infections, alcohols used for umbilical care in newborns, and henna dye used in cosmetics, said Dr. Schachner, professor of pediatrics and dermatology at the University of Miami.

“Any one of those would be excellent toxic substances of the year” that could be the focus of an educational campaign, he told this news organization following his presentation on “Toxicology of Topical Ingredients in Pediatric Dermatology” at the annual meeting of the Society for Pediatric Dermatology on July 14.

Benzene might also be a good candidate for the list, although the jury seems to be still out on its toxicity, said Dr. Schachner.

He talked about the “four Ps” of poisoning — the physician, pharmacy, parents, and pharmaceutical manufacturing — which all have some responsibility for errors that lead to adverse outcomes but can also take steps to prevent them.

During his presentation, Dr. Schachner discussed how babies are especially sensitive to topical therapies, noting that a baby’s skin is thinner and more permeable than that of an adult. And children have a greater body surface-to-weight ratio, so they absorb more substances through their skin.

He also noted that babies lack natural moisturizing factors, and their skin barrier isn’t mature until about age 3-5 years, stressing the need for extreme care when applying a topical agent to a baby’s skin.

Tragic Stories

Dr. Schachner pointed to some instances of mishaps related to toxic topical substances in children. There was the outbreak in the early 1980s of accidental hexachlorophene poisoning among children in France exposed to talc “baby powder.” Of the 204 affected children, 36 died.

The cause was a manufacturing error; the product contained 6.3% hexachlorophene, as opposed to the 0.1% limit recommended by the US Food and Drug Administration (FDA).

Local anesthetics, including lidocaine, dibucaine, and prilocaine, can cause local anesthetic systemic toxicity, a syndrome with symptoms that include central nervous system depression, seizures, and cardiotoxicity. Dr. Schachner described the case of a 3-year-old who developed methemoglobinemia, with seizures, after treatment with an excessive amount of eutectic mixture of local anesthetics (EMLA) cream, which contains both lidocaine and prilocaine.

EMLA shouldn’t be used with methemoglobinemia-inducing agents, such as some antimalarials, analgesics, anesthetics, and antineoplastic agents. It’s not recommended in neonates or for those under 12 months if receiving methemoglobinemia-inducing agents, “and I would keep an eye on it after 12 months of age,” said Dr. Schachner.

He cited a retrospective review of topical lidocaine toxicity in pediatric patients reported to the National Poison Data System from 2000 to 2020. It found 37 cases of toxicity, the most common from application prior to dermatologic procedures (37.5%), which led to two deaths.
 

Not Benign Agents

“These are not benign agents; we have to use them correctly,” Dr. Schachner stressed. When discussing alcohols and antiseptics, he noted that phenol is found in a variety of household disinfectants, gargling products, ointments, and lip balms. Phenol can be used as a chemical peel and is the antiseptic component of Castellani paint. He also referred to cases of alcohol intoxication linked to umbilical care in newborns.

Benzene at elevated levels has been found in some topical benzoyl peroxide acne products and in some sunscreens. There have been suggestions, not strongly substantiated, that benzene may increase the risk for cancer, especially leukemias.

But there is sparse data on the absorption and toxicity of benzene exposure with sunscreen use. The data, he said, include an analysis of National Health and Nutrition Examination Survey data, which found that people who regularly used sunscreens were less likely to have elevated benzene levels compared with those who didn’t use sunscreens.

Turning to insecticides, Dr. Schachner discussed N,N-diethyl-m-toluamide (DEET), the active ingredient in many insect repellents. It helps avoid “some terrible diseases,” including mosquito-borne illnesses such as malaria and tick-borne conditions such as Lyme disease, and is available in several convenient formulations, he said.

When used on children, the American Academy of Pediatrics (AAP) recommends products with no more than 30% DEET. And insect repellents are not recommended for children younger than 2 months, or under clothing or damaged skin, he said.

Dr. Schachner referred to a case series of 18 children who developed DEET-induced encephalopathy; 13 (72%) involved dermal exposure. Three of those with cutaneous exposure died, mostly from neurologic, respiratory, and cardiac issues. “What’s very striking is that 55% of the kids were exposed to DEET of 20% or less, even though the AAP approves DEET at 30%, so maybe that’s something we have to look at,” he said.
 

Medication Patches

With medication patches, especially fentanyl transdermal patches, much can go wrong when it comes to children. This was highlighted by the cases Schachner cited, including an infant who developed acute cytotoxic cerebellar edema from fentanyl patch intoxication.

In another case, emergency room staff found a fentanyl patch stuck to the back of a 3-year-old girl. A CT scan showed global cerebral edema, and the patient progressed to brain death. “This is not a unique case; there have been over 10 such cases in the United States,” said Dr. Schachner. “We should be doing better with fentanyl.”

Nicotine patches can also be dangerous to children, he added. As for other topical agents, there have been reports of toxicity and deaths linked to salicylic acid, commonly used by dermatologists because of its bacteriostatic, fungicidal, keratolytic, and photoprotective properties.

Dr. Schachner cited the case of a 2-month-old where the pediatrician prescribed 50% salicylic acid for seborrheic dermatitis of the scalp, under occlusion. “It’s amazing this child survived; that’s clearly a physician error,” he said.

Henna, a reddish-brown dye derived from the crushed leaves of Lawsonia alba, is used cosmetically for the hair, skin, and nails. Many henna products are mixed with additives, including para-phenylenediamine, which has been associated with dermatitis, asthma, renal failure, and permanent vision loss.

Asked to comment on the presentation, Sheilagh Maguiness, MD, professor of dermatology and pediatrics and chair of pediatric dermatology at the University of Minnesota, Minneapolis, recalled a particularly concerning story in 2008, when the FDA issued a warning about Mommy’s Bliss, a cream containing chlorphenesin and phenoxyethanol as preservatives, promoted to nursing mothers for soothing cracked nipples. There were reports of the cream causing respiratory distress, vomiting, and diarrhea in nursing infants.

Dr. Schachner is chair of Stiefel Laboratories and is an investigator with: Astellas, Berg Pharma, Celgene, Ferndale Labs, Lilly, Medimetriks Pharmaceuticals, Novartis, Organogenesis, Pfizer, Sciton; is a consultant for: Alphyn, Amryt Pharma, Beiersdorf, Brickell, Cutanea, Hoth, Lexington, Mustela, TopMD, Noble Pharma; a speaker for: Novartis, Sanofi-Regeneron, CeraVe; is on the advisory boards of: Almirall, Alphyn, Apogee, Aslan, Biofrontera, CeraVe, Krystal Biotech, Mustela, Noble Pharma, Pfizer, Pierre Fabre, Sanofi-Regeneron; and owns stocks in: TopMD and Alphyn. Dr. Maguiness had no relevant conflicts of interest.

Three of those with cutaneous exposure died, mostly from neurologic, respiratory, and cardiac issues. “What’s very striking is that 55% of the kids were exposed to DEET of 20% or less, even though the AAP approves DEET at 30%, so maybe that’s something we have to look at,” he said.
 

Medication Patches

With medication patches, especially fentanyl transdermal patches, much can go wrong when it comes to children. This was highlighted by the cases Schachner cited, including an infant who developed acute cytotoxic cerebellar edema from fentanyl patch intoxication.

In another case, emergency room staff found a fentanyl patch stuck to the back of a 3-year-old girl. A CT scan showed global cerebral edema, and the patient progressed to brain death. “This is not a unique case; there have been over 10 such cases in the United States,” said Dr. Schachner. “We should be doing better with fentanyl.”

Nicotine patches can also be dangerous to children, he added. As for other topical agents, there have been reports of toxicity and deaths linked to salicylic acid, commonly used by dermatologists because of its bacteriostatic, fungicidal, keratolytic, and photoprotective properties.

Dr. Schachner cited the case of a 2-month-old where the pediatrician prescribed 50% salicylic acid for seborrheic dermatitis of the scalp, under occlusion. “It’s amazing this child survived; that’s clearly a physician error,” he said.

Henna, a reddish-brown dye derived from the crushed leaves of Lawsonia alba, is used cosmetically for the hair, skin, and nails. Many henna products are mixed with additives, including para-phenylenediamine, which has been associated with dermatitis, asthma, renal failure, and permanent vision loss.

Asked to comment on the presentation, Sheilagh Maguiness, MD, professor of dermatology and pediatrics and chair of pediatric dermatology at the University of Minnesota, Minneapolis, recalled a particularly concerning story in 2008, when the FDA issued a warning about Mommy’s Bliss, a cream containing chlorphenesin and phenoxyethanol as preservatives, promoted to nursing mothers for soothing cracked nipples. There were reports of the cream causing respiratory distress, vomiting, and diarrhea in nursing infants.

TORONTO — Lawrence A. Schachner, MD, would like pediatric dermatologists to adopt a “toxic agent of the year” to raise awareness about the potential harm related to certain topical treatments in babies and young children.

Dr. Schachner, director of the Division of Pediatric Dermatology in the Department of Dermatology & Cutaneous Surgery at the University of Miami, Coral Gables, Florida, said he got the idea from the American Contact Dermatitis Society, which annually names the “Allergen of the Year.”

In pediatric dermatology, the list of potentially toxic products includes topical analgesics such as Castellani paint used for skin infections, alcohols used for umbilical care in newborns, and henna dye used in cosmetics, said Dr. Schachner, professor of pediatrics and dermatology at the University of Miami.

“Any one of those would be excellent toxic substances of the year” that could be the focus of an educational campaign, he told this news organization following his presentation on “Toxicology of Topical Ingredients in Pediatric Dermatology” at the annual meeting of the Society for Pediatric Dermatology on July 14.

Benzene might also be a good candidate for the list, although the jury seems to be still out on its toxicity, said Dr. Schachner.

He talked about the “four Ps” of poisoning — the physician, pharmacy, parents, and pharmaceutical manufacturing — which all have some responsibility for errors that lead to adverse outcomes but can also take steps to prevent them.

During his presentation, Dr. Schachner discussed how babies are especially sensitive to topical therapies, noting that a baby’s skin is thinner and more permeable than that of an adult. And children have a greater body surface-to-weight ratio, so they absorb more substances through their skin.

He also noted that babies lack natural moisturizing factors, and their skin barrier isn’t mature until about age 3-5 years, stressing the need for extreme care when applying a topical agent to a baby’s skin.

Tragic Stories

Dr. Schachner pointed to some instances of mishaps related to toxic topical substances in children. There was the outbreak in the early 1980s of accidental hexachlorophene poisoning among children in France exposed to talc “baby powder.” Of the 204 affected children, 36 died.

The cause was a manufacturing error; the product contained 6.3% hexachlorophene, as opposed to the 0.1% limit recommended by the US Food and Drug Administration (FDA).

Local anesthetics, including lidocaine, dibucaine, and prilocaine, can cause local anesthetic systemic toxicity, a syndrome with symptoms that include central nervous system depression, seizures, and cardiotoxicity. Dr. Schachner described the case of a 3-year-old who developed methemoglobinemia, with seizures, after treatment with an excessive amount of eutectic mixture of local anesthetics (EMLA) cream, which contains both lidocaine and prilocaine.

EMLA shouldn’t be used with methemoglobinemia-inducing agents, such as some antimalarials, analgesics, anesthetics, and antineoplastic agents. It’s not recommended in neonates or for those under 12 months if receiving methemoglobinemia-inducing agents, “and I would keep an eye on it after 12 months of age,” said Dr. Schachner.

He cited a retrospective review of topical lidocaine toxicity in pediatric patients reported to the National Poison Data System from 2000 to 2020. It found 37 cases of toxicity, the most common from application prior to dermatologic procedures (37.5%), which led to two deaths.
 

Not Benign Agents

“These are not benign agents; we have to use them correctly,” Dr. Schachner stressed. When discussing alcohols and antiseptics, he noted that phenol is found in a variety of household disinfectants, gargling products, ointments, and lip balms. Phenol can be used as a chemical peel and is the antiseptic component of Castellani paint. He also referred to cases of alcohol intoxication linked to umbilical care in newborns.

Benzene at elevated levels has been found in some topical benzoyl peroxide acne products and in some sunscreens. There have been suggestions, not strongly substantiated, that benzene may increase the risk for cancer, especially leukemias.

But there is sparse data on the absorption and toxicity of benzene exposure with sunscreen use. The data, he said, include an analysis of National Health and Nutrition Examination Survey data, which found that people who regularly used sunscreens were less likely to have elevated benzene levels compared with those who didn’t use sunscreens.

Turning to insecticides, Dr. Schachner discussed N,N-diethyl-m-toluamide (DEET), the active ingredient in many insect repellents. It helps avoid “some terrible diseases,” including mosquito-borne illnesses such as malaria and tick-borne conditions such as Lyme disease, and is available in several convenient formulations, he said.

When used on children, the American Academy of Pediatrics (AAP) recommends products with no more than 30% DEET. And insect repellents are not recommended for children younger than 2 months, or under clothing or damaged skin, he said.

Dr. Schachner referred to a case series of 18 children who developed DEET-induced encephalopathy; 13 (72%) involved dermal exposure.
