CBT or hypnotherapy may help kids’ functional abdominal pain
Functional abdominal pain in childhood and adolescence is extremely stressful for patients and a therapeutic challenge for the physicians treating them. A meta-analysis of 33 randomized-controlled studies published in JAMA Pediatrics shows that cognitive-behavioral therapy or hypnotherapy promises the greatest therapy success.
“If children or adolescents complain about chronic abdominal pain and a detailed diagnostic does not reveal any somatic cause, this is referred to as functional abdominal pain,” Burkhard Rodeck, MD, general secretary of the German Society of Pediatrics and Adolescent Medicine in Berlin, told this news organization.
Signal perception disorder
“These patients are experiencing a signal perception disorder: normal body signals, such as a slight stomach rumble, are assigned to the pain category for them much more quickly than for other people,” said Dr. Rodeck. “The meta-analysis provides confirmation of this – functional abdominal pain is actually a biopsychosocial matter.”
In the standard therapy of functional abdominal pain, however, it is also possible to choose a medicinal approach. “Studies show that herbal preparations such as peppermint oil capsules have some efficacy, since they attenuate the strength of the signals being sent from the gastrointestinal tract to the brain, with the result that they are not perceived so quickly as pain. Probiotics can also potentially help,” added Dr. Rodeck.
“If this is unsuccessful, the child must be offered a psychologic/psychotherapeutic measure, usually cognitive-behavioral therapy.”
Comparison of psychosocial therapies
The meta-analysis was carried out by a research team at the University of Central Lancashire, Preston, United Kingdom. It included 2,657 children and adolescents between the ages of 7 and 17 years, of which two-thirds were girls.
Various psychosocial therapy approaches for functional abdominal pain, such as cognitive-behavioral therapy, educational assistance, hypnotherapy (directed at the digestive system), guided meditation with relaxation, yoga, or (visceral) osteopathy were investigated and compared in the studies – sometimes against each other and sometimes against no intervention.
Lead author Morris Gordon, MBChB, PhD, professor of evidence synthesis and systematic review at the University of Central Lancashire, and his colleagues reported that cognitive-behavioral therapy was 2.37-times more likely to result in therapy success than no intervention. To treat functional abdominal pain successfully in one child or adolescent, five children needed to be treated with cognitive-behavioral therapy.
Rarer, milder pain
The children and adolescents treated with cognitive-behavioral therapy also experienced less frequent and less severe abdominal pain than the children and adolescents who did not receive any intervention. The rate of side effect–related therapy discontinuations did not differ between the groups.
Hypnotherapy could also be associated with an improved outcome, compared with no intervention, added Dr. Gordon and his colleagues. Hypnotherapy was 2.86-times more likely to result in therapy success, and the number needed to treat was five.
The other therapeutic approaches investigated did not perform any better in the studies than no intervention. However, the authors noted that evidence of the effectiveness of cognitive-behavioral therapy and hypnotherapy is moderate or weak, especially owing to the high bias risk.
“The therapy for functional abdominal pain cannot be compared with the therapy for scarlet fever, for example, where penicillin is administered in the knowledge that recovery is guaranteed. There is evidence that cognitive-behavioral therapy and possibly also hypnotherapy may help, but this is not true for every patient,” said Dr. Rodeck.
Start with the pediatrician
Dr. Gordon and his co-authors suggested considering cognitive-behavioral therapy and hypnotherapy for the treatment of functional abdominal pain in children and adolescents. But they added that further randomized controlled studies are necessary to improve the quality of evidence and therefore the reliability of these results.
Children and adolescents with functional abdominal pain do not need to be sent directly to the psychologist for treatment, said Dr. Rodeck. The pediatric or adolescent medicine specialist can also administer the initial behavioral therapy measures. “Some patients manage with the behavioral therapy approaches we offer as pediatric and adolescent medicine specialists; others require professional support with psychologic expertise,” said Dr. Rodeck. Should outpatient treatment be unsuccessful, inpatient therapy in special psychosomatic clinics or wards remains an option.
Education offers relief
For many patients, being informed about the connections and mechanisms that play a role in functional abdominal pain can offer a lot of relief, said Dr. Rodeck. Offering coping strategies that can be used in the event of acute symptoms is also a part of this education.
“If patients have functional abdominal pain for which no organic cause can be found, this can lead to frustration, sadness, and despair. The problem can become even worse if they feel that they are not being taken seriously by the physician,” said Dr. Rodeck. These negative experiences can further exacerbate the pain perception disorder. The aim of behavioral therapy measures is therefore to interrupt and downregulate this vicious cycle.
“Constant investigations are not always helpful for patients with functional abdominal pain. Time must be taken with these patients to talk and explore the options. They have definite abdominal pain, they are not imagining it. They must be taken seriously,” he emphasized.

Maternal autoimmune diseases up risk of mental illness in children
Mental disorders were significantly more likely in children whose mothers had one of five common autoimmune diseases, a new study found.
Previous research has linked both maternal and paternal autoimmune diseases and specific mental disorders, such as attention-deficit/hyperactivity disorder (ADHD), but most of these studies focused on specific conditions in relatively small populations. The new study included data on more than 2 million births, making it one of the largest efforts to date to examine the association, according to the researchers, whose findings were published in JAMA Network Open.
Previous evidence of the possible association between certain maternal autoimmune diseases and mental disorders in offspring has been “scattered and limited,” which “hampered an overall understanding” of the link, Fei Li, MD, the corresponding author of the study, told this news organization.
Dr. Li, of Shanghai Jiao Tong University China, and colleagues reviewed data from a Danish registry cohort of singleton births with up to 38 years of follow-up. They explored associations between a range of maternal autoimmune diseases diagnosed before childbirth and the risks of mental disorders in children in early childhood through young adulthood.
The study population included 2,254,234 births and 38,916,359 person-years. Data on mental health were collected from the Psychiatric Central Research Register and the country’s National Patient Register. The median age of the children at the time of assessment was 16.7 years; approximately half were male.
A total of 50,863 children (2.26%) were born to mothers who had been diagnosed with autoimmune diseases before childbirth. During the follow-up period, 5,460 children of mothers with autoimmune diseases and 303,092 children of mothers without autoimmune diseases were diagnosed with a mental disorder (10.73% vs. 13.76%), according to the researchers.
The risk of being diagnosed with a mental disorder was significantly higher among children of mothers with any autoimmune disease (hazard ratio [HR,], 1.16), with an incidence of 9.38 vs. 7.91 per 1,000 person-years, the researchers reported.
The increased risk persisted when the results were classified by organ system, including connective tissue (HR, 1.11), endocrine (HR, 1.19), gastrointestinal (HR, 1.11), blood (HR, 1.10), nervous (HR, 1.17), and skin (HR, 1.19).
The five autoimmune diseases in mothers that were most commonly associated mental health disorders in children were type 1 diabetes, rheumatoid arthritis, systemic lupus erythematosus, multiple sclerosis, and psoriasis vulgaris.
The greatest risk for children of mothers with any autoimmune disease was observed for organic conditions such as delirium, (HR, 1.54), followed by obsessive-compulsive disorder (HR, 1.42), schizophrenia (HR, 1.54), and mood problems (HR, 1.12).
Children of mothers with any autoimmune disorder also had a significantly increased risk of autism (HR, 1.21), intellectual disability (HR, 1.19), and ADHD (HR, 1.19).
The results add to evidence that activation of the maternal immune system may drive changes in the brain and behavioral problems, which has been observed in animal studies, the researchers wrote.
Potential underlying mechanisms in need of more exploration include genetic risk factors, maternal transmission of autoantibodies to the fetus during pregnancy, and the increased risk of obstetric complications, such as preterm birth, for women with autoimmune disorders that could affect mental development in children, they added.
The study findings were limited by several factors, including the lack of data on potential exacerbation of autoimmune disease activity during pregnancy and its effect on the fetus, the researchers noted. Other limitations included potential detection bias, lack of data on mental disorders in adulthood, and potential changes in diagnostic criteria over the long study period.
The results were strengthened by the use of a population-based registry, the large sample size, and ability to consider a range of confounders, the researchers said.
“This study could help acquire a comprehensive compilation of the associations between maternal autoimmune disorders diagnosed before childbirth and offspring’s mental disorders from childhood through early adulthood,” Dr. Li said in an interview.
For clinicians, Dr. Li said, the findings suggest that the offspring of mothers with autoimmune diseases may benefit from long-term surveillance for mental health disorders.
“Further studies should provide more evidence on the detailed associations of specific maternal autoimmune diseases with a full spectrum of mental disorders in offspring, and more research on underlying mechanisms is needed as well,” she said.
Pay early attention
M. Susan Jay, MD, an adjunct professor of pediatrics at the Medical College of Wisconsin, Milwaukee, said previous efforts to examine the association between maternal autoimmunity were hampered by study design, small samples, and self-report of disease history – problems the new research avoids.
The large patient population allowed for detailed subgroup analysis of different conditions and outcomes. Another advantage was the availability of sociodemographic and clinical information, which allowed for the elimination of confounding factors, said Dr. Jay, who was not involved in the research.
“It would be prudent to follow children of mothers with autoimmune disorders before or during pregnancy for mental health issues, and if identified clinically, to offer psychological and developmental behavioral support options,” Dr. Jay added.
The authors have reported no relevant financial relationships.

Neonatal sepsis morbidity and mortality high across rich and poor countries
LISBON – A shift toward broader-spectrum antibiotics and increasing antibiotic resistance has led to high levels of mortality and neurodevelopmental impacts in surviving babies, according to a large international study conducted on four continents.
Results of the 3-year study were presented at this week’s European Congress of Clinical Microbiology & Infectious Diseases (ECCMID).
The observational study, NeoOBS, conducted by the Global Antibiotic Research and Development Partnership (GARDP) and key partners from 2018 to 2020, explored the outcomes of more than 3,200 newborns, finding an overall mortality of 11% in those with suspected neonatal sepsis. The mortality rate increased to 18% in newborns in whom a pathogen was detected in blood culture.
More than half of infection-related deaths (59%) were due to hospital-acquired infections. Klebsiella pneumoniae was the most common pathogen isolated and is usually associated with hospital-acquired infections, which are increasingly resistant to existing antibiotic treatments, said a report produced by GARDP to accompany the results.
The study also identified a worrying trend: Hospitals are frequently using last-line agents such as carbapenems because of the high degree of antibiotic resistance in their facilities. Of note, 15% of babies with neonatal sepsis were given last-line antibiotics.
Pediatrician Julia Bielicki, MD, PhD, senior lecturer, Paediatric Infectious Diseases Research Group, St. George’s University of London, and clinician at the University of Basel Children’s Hospital, Switzerland, was a coinvestigator on the NeoOBS study.
In an interview, she explained that, as well as reducing mortality, the research is about managing infections better to prevent long-term events and improve the quality of life for survivors of neonatal sepsis. “It can have life-changing impacts for so many babies,” Dr. Bielicki said. “Improving care is much more than just making sure the baby survives the episode of sepsis – it’s about ensuring these babies can become children and adults and go on to lead productive lives.”
Also, only a minority of patients (13%) received the World Health Organization guidelines for standard of care use of ampicillin and gentamicin, and there was increasing use of last-line agents such as carbapenems and even polymyxins in some settings in low- and middle-income countries. “This is alarming and foretells the impending crisis of a lack of antibiotics to treat sepsis caused by multidrug-resistant organisms,” according to the GARDP report.
There was wide variability in antibiotic combinations used across sites in Bangladesh, Brazil, China, Greece, India, Italy, Kenya, South Africa, Thailand, Uganda, and Vietnam, and often such use was not supported by underlying data.
Dr. Bielicki remarked that there was a shift toward broad-spectrum antibiotic use. “In a high-income country, you have more restrictive patterns of antibiotic use, but it isn’t necessarily less antibiotic exposure of neonates to antibiotics, but on the whole, usually narrow-spectrum agents are used.”
In Africa and Asia, on the other hand, clinicians often have to use a broader-spectrum antibiotic empirically and may need to switch to another antibiotic very quickly. “Sometimes alternatives are not available,” she pointed out.
“Local physicians are very perceptive of this problem of antibiotic resistance in their daily practice, especially in centers with high mortality,” said Dr. Bielicki, emphasizing that it is not their fault, but is “due to the limitations in terms of the weapons available to treat these babies, which strongly demonstrates the growing problem of antimicrobial resistance affecting these babies on a global scale.”
Tim Jinks, PhD, Head of Drug Resistant Infections Priority Program at Wellcome Trust, commented on the study in a series of text messages to this news organization. “This research provides further demonstration of the urgent need for improved treatment of newborns suffering with sepsis and particularly the requirement for new antibiotics that overcome the burden of drug-resistant infections caused by [antimicrobial resistance].”
“The study is a hugely important contribution to our understanding of the burden of neonatal sepsis in low- and middle- income countries,” he added, “and points toward ways that patient treatment can be improved to save more lives.”
High-, middle-, and low-income countries
The NeoOBS study gathered data from 19 hospitals in 11 high-, middle-, and low-income countries and assessed which antibiotics are currently being used to treat neonatal sepsis, as well as the degree of drug resistance associated with them. Sites included some in Italy and Greece, where most of the neonatal sepsis data currently originate, and this helped to anchor the data, Dr. Bielicki said.
The study identified babies with clinical sepsis over a 4-week period and observed how these patients were managed, particularly with respect to antibiotics, as well as outcomes including whether they recovered, remained in hospital, or died. Investigators obtained bacterial cultures from the patients and grew them to identify which organisms were causing the sepsis.
Of note, mortality varied widely between hospitals, ranging from 1% to 27%. Dr. Bielicki explained that the investigators were currently exploring the reasons behind this wide range of mortality. “There are lots of possible reasons for this, including structural factors such as how care is delivered, which is complex to measure,” she said. “It isn’t trivial to measure why, in a certain setting, mortality is low and why in another setting of comparable income range, mortality is much higher.”
Aside from the mortality results, Dr. Bielicki also emphasized that the survivors of neonatal sepsis frequently experience neurodevelopmental impacts. “A hospital may have low mortality, but many of these babies may have neurodevelopment problems, and this has a long-term impact.”
“Even though mortality might be low in a certain hospital, it might not be low in terms of morbidity,” she added.
The researchers also collected isolates from the cohort of neonates to determine which antibiotic combinations work against the pathogens. “This will help us define what sort of antibiotic regimen warrants further investigation,” Dr. Bielicki said.
Principal Investigator, Mike Sharland, MD, also from St. George’s, University of London, who is also the Antimicrobial Resistance Program Lead at Penta Child Health Research, said, in a press release, that the study had shown that antibiotic resistance is now one of the major threats to neonatal health globally. “There are virtually no studies underway on developing novel antibiotic treatments for babies with sepsis caused by multidrug-resistant infections.”
“This is a major problem for babies in all countries, both rich and poor,” he stressed.
NeoSep-1 trial to compare multiple different treatments
The results have paved the way for a major new global trial of multiple established and new antibiotics with the goal of reducing mortality from neonatal sepsis – the NeoSep1 trial.
“This is a randomized trial with a specific design that allows us to rank different treatments against each other in terms of effectiveness, safety, and costs,” Dr. Bielicki explained.
Among the antibiotics in the study are amikacin, flomoxef and amikacin, or fosfomycin and flomoxef in babies with sepsis 28 days old or younger. Similar to the NeoOBS study, patients will be recruited from all over the world, and in particular from low- and middle-income countries such as Kenya, South Africa, and other countries in Africa and Southeast Asia.
Ultimately, the researchers want to identify modifiable risk factors and enact change in practice. But Dr. Bielicki was quick to point out that it was difficult to disentangle those factors that can easily be changed. “Some can be changed in theory, but in practice it is actually difficult to change them. One modifiable risk factor that can be changed is probably infection control, so when resistant bacteria appear in a unit, we need to ensure that there is no or minimal transmission between babies.”
Luregn Schlapbach, MD, PhD, Head, department of intensive care and neonatology, University Children’s Hospital Zurich, Switzerland, welcomed the study, saying recent recognition of pediatric and neonatal sepsis was an urgent problem worldwide.
She referred to the 2017 WHO resolution recognizing that sepsis represents a leading cause of mortality and morbidity worldwide, affecting patients of all ages, across all continents and health care systems but that many were pediatric. “At that time, our understanding of the true burden of sepsis was limited, as was our knowledge of current epidemiology,” she said in an email interview. “The Global Burden of Disease study in 2020 revealed that about half of the approximatively 50 million global sepsis cases affect pediatric age groups, many of those during neonatal age.”
The formal acknowledgment of this extensive need emphasizes the “urgency to design preventive and therapeutic interventions to reduce this devastating burden,” Dr. Schlapbach said. “In this context, the work led by GARDP is of great importance – it is designed to improve our understanding of current practice, risk factors, and burden of neonatal sepsis across low- to middle-income settings and is essential to design adequately powered trials testing interventions such as antimicrobials to improve patient outcomes and reduce the further emergence of antimicrobial resistance.”
Dr. Bielicki and Dr. Schlapbach have disclosed no relevant financial relationships.

LISBON – A shift toward broader-spectrum antibiotics and increasing antibiotic resistance has led to high levels of mortality and neurodevelopmental impacts in surviving babies, according to a large international study conducted on four continents.
Results of the 3-year study were presented at this week’s European Congress of Clinical Microbiology & Infectious Diseases (ECCMID).
The observational study, NeoOBS, conducted by the Global Antibiotic Research and Development Partnership (GARDP) and key partners from 2018 to 2020, explored the outcomes of more than 3,200 newborns, finding an overall mortality of 11% in those with suspected neonatal sepsis. The mortality rate increased to 18% in newborns in whom a pathogen was detected in blood culture.
More than half of infection-related deaths (59%) were due to hospital-acquired infections. Klebsiella pneumoniae was the most common pathogen isolated and is usually associated with hospital-acquired infections, which are increasingly resistant to existing antibiotic treatments, said a report produced by GARDP to accompany the results.
The study also identified a worrying trend: Hospitals are frequently using last-line agents such as carbapenems because of the high degree of antibiotic resistance in their facilities. Of note, 15% of babies with neonatal sepsis were given last-line antibiotics.
Pediatrician Julia Bielicki, MD, PhD, senior lecturer, Paediatric Infectious Diseases Research Group, St. George’s University of London, and clinician at the University of Basel Children’s Hospital, Switzerland, was a coinvestigator on the NeoOBS study.
In an interview, she explained that, as well as reducing mortality, the research is about managing infections better to prevent long-term events and improve the quality of life for survivors of neonatal sepsis. “It can have life-changing impacts for so many babies,” Dr. Bielicki said. “Improving care is much more than just making sure the baby survives the episode of sepsis – it’s about ensuring these babies can become children and adults and go on to lead productive lives.”
Also, only a minority of patients (13%) received the World Health Organization guidelines for standard of care use of ampicillin and gentamicin, and there was increasing use of last-line agents such as carbapenems and even polymyxins in some settings in low- and middle-income countries. “This is alarming and foretells the impending crisis of a lack of antibiotics to treat sepsis caused by multidrug-resistant organisms,” according to the GARDP report.
There was wide variability in antibiotic combinations used across sites in Bangladesh, Brazil, China, Greece, India, Italy, Kenya, South Africa, Thailand, Uganda, and Vietnam, and often such use was not supported by underlying data.
Dr. Bielicki remarked that there was a shift toward broad-spectrum antibiotic use. “In a high-income country, you have more restrictive patterns of antibiotic use, but it isn’t necessarily less antibiotic exposure of neonates to antibiotics, but on the whole, usually narrow-spectrum agents are used.”
In Africa and Asia, on the other hand, clinicians often have to use a broader-spectrum antibiotic empirically and may need to switch to another antibiotic very quickly. “Sometimes alternatives are not available,” she pointed out.
“Local physicians are very perceptive of this problem of antibiotic resistance in their daily practice, especially in centers with high mortality,” said Dr. Bielicki, emphasizing that it is not their fault, but is “due to the limitations in terms of the weapons available to treat these babies, which strongly demonstrates the growing problem of antimicrobial resistance affecting these babies on a global scale.”
Tim Jinks, PhD, Head of Drug Resistant Infections Priority Program at Wellcome Trust, commented on the study in a series of text messages to this news organization. “This research provides further demonstration of the urgent need for improved treatment of newborns suffering with sepsis and particularly the requirement for new antibiotics that overcome the burden of drug-resistant infections caused by [antimicrobial resistance].”
“The study is a hugely important contribution to our understanding of the burden of neonatal sepsis in low- and middle- income countries,” he added, “and points toward ways that patient treatment can be improved to save more lives.”
High-, middle-, and low-income countries
The NeoOBS study gathered data from 19 hospitals in 11 high-, middle-, and low-income countries and assessed which antibiotics are currently being used to treat neonatal sepsis, as well as the degree of drug resistance associated with them. Sites included some in Italy and Greece, where most of the neonatal sepsis data currently originate, and this helped to anchor the data, Dr. Bielicki said.
The study identified babies with clinical sepsis over a 4-week period and observed how these patients were managed, particularly with respect to antibiotics, as well as outcomes including whether they recovered, remained in hospital, or died. Investigators obtained bacterial cultures from the patients and grew them to identify which organisms were causing the sepsis.
Of note, mortality varied widely between hospitals, ranging from 1% to 27%. Dr. Bielicki explained that the investigators were currently exploring the reasons behind this wide range of mortality. “There are lots of possible reasons for this, including structural factors such as how care is delivered, which is complex to measure,” she said. “It isn’t trivial to measure why, in a certain setting, mortality is low and why in another setting of comparable income range, mortality is much higher.”

Children and COVID: New cases up for third straight week
Moderna submitted a request to the Food and Drug administration for emergency use authorization of its COVID-19 vaccine in children under the age of 6 years, according to this news organization, and Pfizer/BioNTech officially applied for authorization of a booster dose in children aged 5-11, the companies announced.
The FDA has tentatively scheduled meetings of its Vaccines and Related Biological Products Advisory Committee in June to consider the applications, saying that it “understands the urgency to authorize a vaccine for age groups who are not currently eligible for vaccination and will work diligently to complete our evaluation of the data. Should any of the submissions be completed in a timely manner and the data support a clear path forward following our evaluation, the FDA will act quickly” to convene the necessary meetings.
The need for greater access to vaccines seems to be increasing, as new pediatric COVID cases rose for the third consecutive week. April 22-28 saw over 53,000 new cases reported in children, up 43.5% from the previous week and up 105% since cases started rising again after dipping under 26,000 during the week of April 1-7, based on data from the American Academy of Pediatrics and the Children’s Hospital Association.
Hospital admissions involving diagnosed COVID also ticked up over the latter half of April, although the most recent 7-day average (April 24-30) of 112 per day was lower than the 117 reported for the previous week (April 17-23), the Centers for Disease Control and Prevention said, also noting that figures for the latest week “should be interpreted with caution.”
Vaccinations also were up slightly in children aged 5-11 years, with 52,000 receiving their first dose during the week of April 21-27, compared with 48,000 the week before. There was a slight dip, however, among 12- to 17-year-olds, who received 34,000 first doses during April 21-27, versus 35,000 the previous week, the AAP said in a separate report.
Cumulatively, almost 69% of all children aged 12-17 years have received at least one dose of the COVID-19 vaccine and 59% are fully vaccinated. Those aged 5-11 are well short of those figures, with just over 35% having received at least one dose and 28.5% fully vaccinated, the CDC said on its COVID Data Tracker.
A look at recent activity shows that children are not gaining on adults, who are much more likely to be vaccinated – full vaccination in those aged 50-64, for example, is 80%. During the 2 weeks from April 17-30, the 5- to 11-year-olds represented 10.5% of those who had initiated a first dose and 12.4% of those who gained full-vaccination status, both of which were well below the oldest age groups, the CDC reported.

WHO, UNICEF warn about increased risk of measles outbreaks
The World Health Organization and United Nations International Children’s Emergency Fund are warning about a heightened risk of measles spreading and triggering larger outbreaks in 2022.
Worldwide cases are up nearly 80% so far over 2021, the groups reported. More than 17,300 measles cases were reported worldwide in January and February, compared with 9,600 cases at the beginning of 2021.
In the last 12 months, there have been 21 “large and disruptive” measles outbreaks, particularly in Africa and the East Mediterranean region. The actual numbers are likely higher because of underreporting and disruptions to surveillance systems.
“Pandemic-related disruptions, increasing inequalities in access to vaccines, and the diversion of resources from routine immunization are leaving too many children without protection against measles and other vaccine-preventable diseases,” the organizations said.
As cities and countries relax COVID-19 restrictions, measles outbreaks are becoming more likely, they noted.
“It is encouraging that people in many communities are beginning to feel protected enough from COVID-19 to return to more social activities. But doing so in places where children are not receiving routine vaccination creates the perfect storm for the spread of a disease like measles,” Catherine Russell, executive director for UNICEF, said in the statement.
In the past year, the largest measles outbreaks have occurred in Somalia, Yemen, Nigeria, Afghanistan, and Ethiopia. The main reason for outbreaks is a lack measles vaccine coverage, the organizations said.
About 23 million children missed childhood vaccinations in 2020, the groups said. Childhood vaccination campaigns were hindered because of the COVID-19 pandemic and conflicts in Ukraine, Ethiopia, Somalia, and Afghanistan.
Overall, 57 campaigns targeting vaccine-preventable diseases across 43 countries that were scheduled to take place since the beginning of the COVID-19 pandemic are still postponed, the groups said, which could affect 203 million people. Among those, 19 are measles campaigns, which could put 73 million children at risk of measles because of missed vaccinations.
Vaccine coverage of 95% or higher with two doses of the measles vaccine can provide protection, according to the organizations. But the five countries that had the highest measles cases in the last year had first-dose coverage between 46% and 68%.
In the United States, measles vaccinations in kindergarten students dropped from about 95% to 93.9% for the 2020-2021 school year, according to CNN.
Vaccination coverage also dropped from 95% to 93.6% for diphtheria, tetanus, acellular pertussis, and varicella. Even though the decreases appear small, it means tens of thousands of children across the United States started school without their common childhood vaccinations, the Centers for Disease Control and Prevention said.
“We are concerned that missed routine vaccinations could leave children vulnerable to preventable diseases like measles and whooping cough, which are extremely contagious and can be very serious, especially for babies and young children,” Shannon Stokley, DrPH, deputy director of the CDC’s immunization services division, told CNN.
The numbers show a “concerning decline in childhood immunizations that began in March 2020,” she said.

Vaccine coverage of 95% or higher with two doses of the measles vaccine can provide protection, according to the organizations. But the five countries that had the highest measles cases in the last year had first-dose coverage between 46% and 68%.
In the United States, measles vaccinations in kindergarten students dropped from about 95% to 93.9% for the 2020-2021 school year, according to CNN.
Vaccination coverage also dropped from 95% to 93.6% for diphtheria, tetanus, acellular pertussis, and varicella. Even though the decreases appear small, it means tens of thousands of children across the United States started school without their common childhood vaccinations, the Centers for Disease Control and Prevention said.
“We are concerned that missed routine vaccinations could leave children vulnerable to preventable diseases like measles and whooping cough, which are extremely contagious and can be very serious, especially for babies and young children,” Shannon Stokley, DrPH, deputy director of the CDC’s immunization services division, told CNN.
The numbers show a “concerning decline in childhood immunizations that began in March 2020,” she said.

The World Health Organization and United Nations International Children’s Emergency Fund are warning about a heightened risk of measles spreading and triggering larger outbreaks in 2022.
Worldwide cases are up nearly 80% so far over 2021, the groups reported. More than 17,300 measles cases were reported worldwide in January and February, compared with 9,600 cases at the beginning of 2021.
In the last 12 months, there have been 21 “large and disruptive” measles outbreaks, particularly in Africa and the East Mediterranean region. The actual numbers are likely higher because of underreporting and disruptions to surveillance systems.
“Pandemic-related disruptions, increasing inequalities in access to vaccines, and the diversion of resources from routine immunization are leaving too many children without protection against measles and other vaccine-preventable diseases,” the organizations said.
As cities and countries relax COVID-19 restrictions, measles outbreaks are becoming more likely, they noted.
“It is encouraging that people in many communities are beginning to feel protected enough from COVID-19 to return to more social activities. But doing so in places where children are not receiving routine vaccination creates the perfect storm for the spread of a disease like measles,” Catherine Russell, executive director for UNICEF, said in the statement.
In the past year, the largest measles outbreaks have occurred in Somalia, Yemen, Nigeria, Afghanistan, and Ethiopia. The main reason for outbreaks is a lack measles vaccine coverage, the organizations said.
About 23 million children missed childhood vaccinations in 2020, the groups said. Childhood vaccination campaigns were hindered because of the COVID-19 pandemic and conflicts in Ukraine, Ethiopia, Somalia, and Afghanistan.
Overall, 57 campaigns targeting vaccine-preventable diseases across 43 countries that were scheduled to take place since the beginning of the COVID-19 pandemic are still postponed, the groups said, which could affect 203 million people.

Unexplained hepatitis cases in children reported in 10 U.S. states, more than 200 worldwide
Health officials are investigating at least 30 cases of severe hepatitis in children across 10 U.S. states. The Minnesota Department of Health received two reports of severe hepatitis, one in an infant and another in a 2-year-old, the Associated Press reported on April 30. One child was treated “several months ago” and required a liver transplant, according to the article.
Worldwide cases surpass 200, including 34 cases in the United Kingdom, the U.K. Health Security Agency announced on April 29. Most cases have occurred in the United Kingdom, but there have been more than 55 probable and confirmed hepatitis cases in children in 12 countries in the European Union or the European Economic Area. Cases have also been identified in Asia, with both Japan and Singapore reporting one case each of acute hepatitis, Bloomberg reported. Additionally, three children in Indonesia died from acute hepatitis in April, but the total number of cases in that country was not available.
Although the total number of worldwide cases remains small, the severity of the cases – as well as their unexplained cause – have health officials on alert, said David Lee Thomas, MD, MPH, of the Viral Hepatitis Center at Johns Hopkins Medicine in Baltimore. “There are some kids who would have died if not for liver transplants.”
In the United States, the only confirmed cases are in Alabama, where nine patients were admitted for severe hepatitis between October 2021 and February 2022. Beyond the two suspected cases in Minnesota, health officials are investigating at least 19 other potential cases in eight states, according to NBC News: Delaware (1), Georgia, Illinois (3), Louisiana (1), New York, North Carolina (2), Tennessee (6), and Wisconsin (4). (New York and Georgia did not specify the number of cases being investigated.)
Reported cases have occurred in patients aged between 1 month and 16 years old. Globally, at least 17 patients have needed liver transplants, according to a World Health Organization alert on April 23. While WHO officials said there has been at least one death globally linked to hepatitis, that does not include the three deaths in Indonesia. One death has also been reported in Wisconsin, but the state’s Department of Health Services did not confirm whether this death was included in the WHO announcement.
The cause of these severe hepatitis cases has yet to be identified, but these cases have tested negative for more common viruses that can cause hepatitis in children. There is no link between these cases and COVID-19 vaccination, according to WHO, because most affected children have not been vaccinated.
Adenovirus is a possible contributing factor in these cases, as many of the cases in Europe tested positive for the virus. In an analysis of the nine Alabama cases released by the Centers for Disease Control and Prevention, adenovirus was detected in the blood samples of all nine children. Five of the nine children tested positive for adenovirus type 41, which is a common cause of acute gastroenteritis in children. While the six liver biopsies performed showed varying degrees of hepatitis, there were “no viral inclusions observed, no immunohistochemical evidence of adenovirus, or no viral particles identified by electron microscopy,” according to the report. None of the children tested positive for COVID-19 or had a documented history of previous COVID-19 infection.
“At this time, we believe that adenovirus may be the cause for these reported cases, but other potential environmental and situational factors are still being investigated,” the CDC said in a media statement. The CDC added that the report was specific to the nine Alabama cases, and that the agency is working to investigate other potential cases with state and local public health officials.
While the “growing consensus” among experts is that adenovirus could be behind these severe cases, there are many unanswered questions, Dr. Thomas added, such as why this strain of adenovirus causes such severe hepatitis, and why the liver biopsies do not show classic signs of viral infection. That information will come as investigations continue.
“From a provider point of view, if you have a child with an unexplained liver problem, report it to the CDC,” he advised. “Right now, we have to learn more about [these cases],” and that requires more research like the investigations in Alabama, he noted.

Experts show how to reduce school-related sedentary behavior
The Sedentary Behavior Research Network has published new guidelines “to provide guidance to parents, educators, policy makers, researchers, and health care providers” on means to reduce school-related sedentary behavior.
The recommendations, published in the International Journal of Behavioral Nutrition and Physical Activity were written by researchers led by Travis J. Saunders, PhD, associate professor of applied human sciences at the University of Prince Edward Island, Charlottetown. Based on work carried out by a panel of international experts and informed by the best available evidence and stakeholder consultation, “these recommendations will be useful in supporting the physical and mental health, well-being, and academic success of school-age children and youth,” according to the authors.
The key strength of their work, they wrote, is that it is based on robust scientific data and specifically refers to school-related sedentary behaviors, whether these occur during lessons in the classroom or while completing assignments at home. “Existing sedentary behavior guidelines for children and youth target overall sedentary behavior and recreational screen time, without any specific recommendations regarding school-related sedentary behaviors.” The article also mentions the impact of the COVID-19 pandemic. Lack of movement was already a problem in these age groups; social distancing and distance learning over such an extended period only made things worse.
Risks and benefits
Dr. Saunders and colleagues wrote: “The relationships between sedentary behaviors and student health and academic outcomes are complex and likely differ for specific sedentary behaviors.”
While on one hand sedentary behavior may have a significant negative impact on metabolic outcomes, there is evidence that higher durations of homework and reading are associated with better academic achievement among school-aged children.
Another example of this complexity is that screen-based sedentary behaviors (spending time in front of computer screens, TVs, tablets, smartphones) often demonstrate deleterious associations with a range of health outcomes among school-aged children and youth aged 5-18 years, including body composition, cardiometabolic risk, and self-esteem. Yet screen-based devices may offer opportunities for novel pedagogic approaches and student engagement and may increase access to education for some students, especially during the COVID-19 pandemic.
The researchers noted that “many common sedentary activities ... do not have to be sedentary in nature. These behaviors are only considered to be sedentary when combined with both low energy expenditure and a sitting, reclining, or lying posture.” As an example, they pointed out that “active video gaming, or paper-based work at a standing desk, are both ways that common sedentary behaviors can be made nonsedentary.”
One thing’s for sure: Children and teenagers don’t move around all that much.
Data from the 2019 Eye on Health survey found that one of five children (20.3%) had not engaged in any physical activity the day before the survey, almost half (43.5%) had a TV in their bedroom, and about the same number (44.5%) spent more than 2 hours a day in front of a screen.
As for schools, the survey showed that, while 93% had initiatives to promote physical activity, fewer than 30% of these programs involved parents. It should be kept in mind that these are prepandemic numbers.
‘A healthy school day’
The authors recommend the following for reducing school-related sedentary behavior:
- Break up periods of extended sedentary behavior with both scheduled and unscheduled movement breaks: at least once every 30 minutes for ages 5-11 years and at least once every hour for ages 12-18 years. Consider activities that vary in intensity and duration (for example, standing, stretching breaks, moving to another classroom, active lessons, active breaks).
- Incorporate different types of movement into homework whenever possible, and limit sedentary homework to no more than 10 minutes per day per grade level (for example, no more than 10 minutes per day in grade 1, or 60 minutes per day in grade 6).
- Regardless of the location, school-related screen time should be meaningful, mentally or physically active, and serve a specific pedagogic purpose that enhances learning, compared with alternative methods. When school-related screen time is warranted, the following are recommended: limit time on devices, especially for students age 5-11 years; take a device break at least once every 30 minutes; discourage media multitasking in the classroom and while doing homework; and avoid screen-based homework within an hour of bedtime.
- Replace sedentary learning activities with movement-based learning activities (including standing) and replacing screen-based learning activities with non–screen-based learning activities (for example, outdoor lessons) can further support students’ health and well-being.
“Given the important role that schools can play in the promotion of healthy behaviors,” Dr. Saunders and associates wrote, “we encourage national and international public health agencies to consider inclusion of specific recommendations related to the school environment in future sedentary behavior guidelines.”

FROM THE INTERNATIONAL JOURNAL OF BEHAVIORAL NUTRITION AND PHYSICAL ACTIVITY
Premature return to play after concussion has decreased
, according to a recent chart review. Rates of premature return to learn (RTL) are essentially unchanged, however.
“Delay in recovery is the major reason why it’s important not to RTL or RTP prematurely,” said James Carson, MD, associate professor of family and community medicine, University of Toronto.
“That delay in recovery only sets students further back in terms of the stress they get from being delayed with their schoolwork – they could lose their year in school, lose all their social contacts. So, there are a number of psychosocial issues that come into play if recovery is delayed, and that is what premature RTL and premature RTP will do – they delay the student’s recovery,” he emphasized.
The study was published in Canadian Family Physician.
Differences by sex
The study involved 241 students who had 258 distinct cases of SRC. The researchers defined premature RTP and RTL as chart records documenting the relapse, recurrence, or worsening of concussion symptoms that accompanied the patient’s RTP or RTL. Between 2011 and 2016, 26.7% of students had evidence of premature RTP, while 42.6% of them had evidence of premature RTL, the authors noted.
Compared with findings from an earlier survey of data from 2006 to 2011, the incidence of premature RTP dropped by 38.6% (P = .0003). In contrast, symptoms associated with premature RTL dropped by only 4.7% from the previous survey. This change was not statistically significant.
There was also a significant difference between males and females in the proportion of SRC cases with relapse of symptoms. Relapse occurred in 43.4% of female athletes with SRC versus 29.7% of male athletes with SRC (P = .023).
Female athletes also had significantly longer times before being cleared for RTP. The mean time was 74.5 days for females, compared with a mean of 42.3 days for male athletes (P < .001). “The median time to RTP clearance was nearly double [for female athletes] at 49 days versus 25 days [for male athletes],” wrote the authors.
The rate of premature RTL was also higher among secondary school students (48.8%), compared with 28% among elementary students and 42% among postsecondary students.
More concussions coming?
Before the first consensus conference, organized by the Concussion in Sport Group in 2001, management of concussion was based on rating and grading scales that had no medical evidence to support them, said Dr. Carson. After the consensus conference, it was recommended that physicians manage each concussion individually and, when it came to RTP, recommendations were based upon symptom resolution.
In contrast, there was nothing in the literature regarding how student athletes who sustain a concussion should RTL. Some schools made generous accommodations, and others none. This situation changed around 2011, when experts started publishing data about how better to accommodate student athletes who have a temporary disability for which schools need to introduce temporary accommodations to help them recover.
“Recommendations for RTP essentially had a 12-year head-start,” Dr. Carson emphasized, “and RTL had a much slower start.” Unfortunately, Dr. Carson foresees more athletes sustaining concussions as pandemic restrictions ease over the next few months. “As athletes RTP after the pandemic, they just will not be in game shape,” he said.
“In other words, athletes may not have the neuromuscular control to avoid these injuries as easily,” he added. Worse, athletes may not realize they are not quite ready to return to the expected level of participation so quickly. “I believe this scenario will lead to more concussions that will be difficult to manage in the context of an already strained health care system,” said Dr. Carson.
A limitation of the study was that it was difficult to assess whether all patients followed medical advice consistently.
“Very positive shifts”
Commenting on the findings, Nick Reed, PhD, Canada research chair in pediatric concussion and associate professor of occupational science and occupational therapy, University of Toronto, said that sports medicine physicians are seeing “very positive shifts” in concussion awareness and related behaviors such as providing education, support, and accommodations to students within the school environment. “More and more teachers are seeking education to learn what a concussion is and what to do to best support their students with concussion,” he said. Dr. Reed was not involved in the current study.
Indeed, this increasing awareness led to the development of a concussion education tool for teachers – SCHOOLFirst – although Dr. Reed did acknowledge that not all teachers have either the knowledge or the resources they need to optimally support their students with concussion. In the meantime, to reduce the risk of injury, Dr. Reed stressed that it is important for students to wear equipment appropriate for the game being played and to play by the rules.
“It is key to play sports in a way that is fair and respectful and not [engage] in behaviors with the intent of injuring an opponent,” he stressed. It is also important for athletes themselves to know the signs and symptoms of concussion and, if they think they have a concussion, to immediately stop playing, report how they are feeling to a coach, teacher, or parent, and to seek medical assessment to determine if they have a concussion or not.
“The key here is to focus on what the athlete can do after a concussion rather than what they can’t do,” Dr. Reed said. After even a few days of complete rest, students with a concussion can gradually introduce low levels of physical and cognitive activity that won’t make their symptoms worse. This activity can include going back to school with temporary accommodations in place, such as shorter school days and increased rest breaks. “When returning to school and to sport after a concussion, it is important to follow a stepwise and gradual return to activities so that you aren’t doing too much too fast,” Dr. Reed emphasized.
The study was conducted without external funding. Dr. Carson and Dr. Reed reported no conflicts of interest.

, according to a recent chart review. Rates of premature return to learn (RTL) are essentially unchanged, however.
“Delay in recovery is the major reason why it’s important not to RTL or RTP prematurely,” said James Carson, MD, associate professor of family and community medicine, University of Toronto.
“That delay in recovery only sets students further back in terms of the stress they get from being delayed with their schoolwork – they could lose their year in school, lose all their social contacts. So, there are a number of psychosocial issues that come into play if recovery is delayed, and that is what premature RTL and premature RTP will do – they delay the student’s recovery,” he emphasized.
The study was published in Canadian Family Physician.
Differences by sex
The study involved 241 students who had 258 distinct cases of SRC. The researchers defined premature RTP and RTL as chart records documenting the relapse, recurrence, or worsening of concussion symptoms that accompanied the patient’s RTP or RTL. Between 2011 and 2016, 26.7% of students had evidence of premature RTP, while 42.6% of them had evidence of premature RTL, the authors noted.
Compared with findings from an earlier survey of data from 2006 to 2011, the incidence of premature RTP dropped by 38.6% (P = .0003). In contrast, symptoms associated with premature RTL dropped by only 4.7% from the previous survey. This change was not statistically significant.
There was also a significant difference between males and females in the proportion of SRC cases with relapse of symptoms. Relapse occurred in 43.4% of female athletes with SRC versus 29.7% of male athletes with SRC (P = .023).
Female athletes also had significantly longer times before being cleared for RTP. The mean time was 74.5 days for females, compared with a mean of 42.3 days for male athletes (P < .001). “The median time to RTP clearance was nearly double [for female athletes] at 49 days versus 25 days [for male athletes],” wrote the authors.
The rate of premature RTL was also higher among secondary school students (48.8%), compared with 28% among elementary students and 42% among postsecondary students.
More concussions coming?
Before the first consensus conference, organized by the Concussion in Sport Group in 2001, management of concussion was based on rating and grading scales that had no medical evidence to support them, said Dr. Carson. After the consensus conference, it was recommended that physicians manage each concussion individually and, when it came to RTP, recommendations were based upon symptom resolution.
In contrast, there was nothing in the literature regarding how student athletes who sustain a concussion should RTL. Some schools made generous accommodations, and others none. This situation changed around 2011, when experts started publishing data about how better to accommodate student athletes who have a temporary disability for which schools need to introduce temporary accommodations to help them recover.
“Recommendations for RTP essentially had a 12-year head-start,” Dr. Carson emphasized, “and RTL had a much slower start.” Unfortunately, Dr. Carson foresees more athletes sustaining concussions as pandemic restrictions ease over the next few months. “As athletes RTP after the pandemic, they just will not be in game shape,” he said.
“In other words, athletes may not have the neuromuscular control to avoid these injuries as easily,” he added. Worse, athletes may not realize they are not quite ready to return to the expected level of participation so quickly. “I believe this scenario will lead to more concussions that will be difficult to manage in the context of an already strained health care system,” said Dr. Carson.
A limitation of the study was that it was difficult to assess whether all patients followed medical advice consistently.

Vegetarian diet as good for children, with slight risk of underweight
With more families placing their children on vegetarian diets, the results from a Canadian longitudinal cohort study are reassuring: It found no clinically meaningful differences in height, growth, or biochemical measures of nutrition in young children on vegetarian and nonvegetarian diets.
While z scores (the standard deviation above or below the mean) were similar in both dietary groups, there was a weak association between a vegetarian diet and lower mean z height, as well as slightly higher odds of underweight.
No significant associations were identified between vegetarian and nonvegetarian diets for child z body mass index (BMI), serum ferritin, 25(OH)D, and serum lipids, according to Jonathon L. Maguire, MD. MSc, of St. Michael’s Hospital Pediatric Clinic in Toronto.
Moreover, the magnitude of the height and vegetarian diet association was small at just 0.3 cm for a 3-year-old child and unlikely to be clinically meaningful, Dr. Maguire and colleagues wrote online in Pediatrics.
In a secondary study outcome, cow’s milk consumption was associated with higher serum lipid levels for both diets. Serum lipids were similar among those who did or did not consume a vegetarian diet and consumed the recommended 2 cups of cow’s milk per day.
“The vast majority of children with vegetarian diets have similar growth and nutrition as children without vegetarian diets,” said Dr. Maguire, who is also a professor of pediatrics and nutritional sciences at the University of Toronto, in an interview. “But, I think we should be mindful to carefully plan vegetarian diets for children [who are] underweight.”
The study conclusion was based on 8,907 children, 6 months to 8 years of age, including 248 vegetarian and 25 vegan children, at baseline. They were part of theTARGet Kids! practice-based research network in Toronto.
The mean age of children at baseline was 2.2 years (standard deviation, 1.5), and 52.4% were male. Participants were followed for an average of 2.8 years (SD, 1.7).
Those with a vegetarian diet had longer breastfeeding duration: 12.6 months (SD, 9.5) versus 10.0 months (SD, 7.0). They were also more likely to be of Asian ethnicity: 33.8% versus 19.0%. Otherwise, children with and without a vegetarian diet were similar at baseline.
In study outcomes, vegetarian children had higher odds of underweight: body mass index z score less than –2 (odds ratio 1.87; 95% confidence interval, 1.19-2.96, P = .007), while no association with overweight or obesity was found.
In a secondary outcome, cow’s milk consumption was associated with higher levels of non–high-density lipoprotein cholesterol (P = .03), total cholesterol (P = .04), and low-density lipoprotein cholesterol (P = .02) in young children on a vegetarian diet. Levels were similar in children with and without a vegetarian diet who consumed the recommended 2 cups of cow’s milk per day.
Previous studies have found that vegetarian children have normal growth and development but tend to be leaner than their omnivore peers.
As for the potential effect of following a fully vegan diet on these nutritional measures, Dr. Maguire said, “Unfortunately, there were not enough children with vegan diets to make meaningful conclusions.”
Would results likely be similar in older children who have more independence and engage more with their peers?“ I don’t know, but we will be following these children for many years to come through the TARGet Kids! research network, Dr. Maguire said.
Studies such as this are timely as plant-based eating becomes more widespread in the United States. The 2007-2010 National Health and Nutrition Examination Surveys found that 2.1% of American adults followed a vegetarian diet, and that figure appears to have increased, with 5% of American adults self-identifying as vegetarian in a 2019 Gallup poll.
Offering her perspective on the Canadian study but not involved in it, Stephanie Di Figlia-Peck, MS, RDN, agreed the results indicate that “a vegetarian diet is not a negative thing for growth and development.” She is a lead registered dietitian in the division of adolescent medicine at Cohen Children’s Medical Center in New Hyde Park, N.Y. She noted, however, that the study looked only at very young children on average.
She stressed that vegetarian regimens require family commitment and agreed on the need for planning. “For these diets to work, a lot has to go into it. But if they’re carefully planned, there is adequate protein and micro- and macronutrients and there’s a nonnegative effect on growth and development.”
The study results mirror what she sees in clinical practice, with vegetarian children tending to weigh less. “Some obese and overweight children will adopt vegetarian diets to lose weight,” Ms. Di Figlia-Peck said.
And perseverance has rewards. “When people follow a vegetarian diet, they tend to have lower blood pressure and cholesterol. A plant-based diet can favorably impact diseases for an entire lifetime.”
This study was supported by the Canadian Institutes of Health Research and the St. Michael’s Hospital and SickKids Hospital foundations. Dr. Maguire received an unrestricted research grant for a previous investigator-initiated study from Dairy Farmers of Canada, and D drops provided nonfinancial support (vitamin D supplements) for a previous investigator-initiated study on vitamin D and respiratory tract infections. Coauthor David Jenkins, MD, PhD, DSc, reported research support from multiple private-sector and nonprivate organizations; several of his family members are involved in the promotion of vegetarian diets. Ms. Di Figlia-Peck had no competing interests to declare.

FROM PEDIATRICS
Antibiotics use and vaccine antibody levels
In this column I have previously discussed the microbiome and its importance to health, especially as it relates to infections in children. Given the appreciated connection between microbiome and immunity, my group in Rochester, N.Y., recently undertook a study of the effect of antibiotic usage on the immune response to routine early childhood vaccines. In mouse models, it was previously shown that antibiotic exposure induced a reduction in the abundance and diversity of gut microbiota that in turn negatively affected the generation and maintenance of vaccine-induced immunity.1,2 A study from Stanford University was the first experimental human trial of antibiotic effects on vaccine responses. Adult volunteers were given an antibiotic or not before seasonal influenza vaccination and the researchers identified specific bacteria in the gut that were reduced by the antibiotics given. Those normal bacteria in the gut microbiome were shown to provide positive immunity signals to the systemic immune system that potentiated vaccine responses.3
My group conducted the first-ever study in children to explore whether an association existed between antibiotic use and vaccine-induced antibody levels. In the May issue of Pediatrics we report results from 560 children studied.4 From these children, 11,888 serum antibody levels to vaccine antigens were measured. Vaccine-induced antibody levels were determined at various time points after primary vaccination at child age 2, 4, and 6 months and boosters at age 12-18 months for 10 antigens included in four vaccines: DTaP, Hib, IPV, and PCV. The antibody levels to vaccine components were measured to DTaP (diphtheria toxoid, pertussis toxoid, tetanus toxoid, pertactin, and filamentous hemagglutinin), Hib conjugate (polyribosylribitol phosphate), IPV (polio 2), and PCV (serotypes 6B, 14, and 23F). A total of 342 children with 1,678 antibiotic courses prescribed were compared with 218 children with no antibiotic exposures. The predominant antibiotics prescribed were amoxicillin, cefdinir, amoxicillin/clavulanate, and ceftriaxone, since most treatments were for acute otitis media.
Of possible high clinical relevance, we found that from 9 to 24 months of age, children with antibiotic exposure had a higher frequency of vaccine-induced antibody levels below protection compared with children with no antibiotic use, placing them at risk of contracting a vaccine-preventable infection for DTaP antigens DT, TT, and PT and for PCV serotype 14.
For time points where antibody levels were determined within 30 days of completion of a course of antibiotics (recent antibiotic use), individual antibiotics were analyzed for effect on antibody levels below protective levels. Across all vaccine antigens measured, we found that all antibiotics had a negative effect on antibody levels and percentage of children achieving the protective antibody level threshold. Amoxicillin use had a lower association with lower antibody levels than the broader spectrum antibiotics, amoxicillin clavulanate (Augmentin), cefdinir, and ceftriaxone. For children receiving amoxicillin/clavulanate prescriptions, it was possible to compare the effect of shorter versus longer courses and we found that a 5-day course was associated with subprotective antibody levels similar to 10 days of amoxicillin, whereas 10-day amoxicillin/clavulanate was associated with higher frequency of children having subprotective antibody levels (Figure).
We examined whether accumulation of antibiotic courses in the first year of life had an association with subsequent vaccine-induced antibody levels and found that each antibiotic prescription was associated with a reduction in the median antibody level. For DTaP, each prescription was associated with 5.8% drop in antibody level to the vaccine components. For Hib the drop was 6.8%, IPV was 11.3%, and PCV was 10.4% – all statistically significant. To determine if booster vaccination influenced this association, a second analysis was performed using antibiotic prescriptions up to 15 months of age. We found each antibiotic prescription was associated with a reduction in median vaccine-induced antibody levels for DTaP by 18%, Hib by 21%, IPV by 19%, and PCV by 12% – all statistically significant.
Our study is the first in young children during the early age window where vaccine-induced immunity is established. Antibiotic use was associated with increased frequency of subprotective antibody levels for several vaccines used in children up to 2 years of age. The lower antibody levels could leave children vulnerable to vaccine preventable diseases. Perhaps outbreaks of vaccine-preventable diseases, such as pertussis, may be a consequence of multiple courses of antibiotics suppressing vaccine-induced immunity.
A goal of this study was to explore potential acute and long-term effects of antibiotic exposure on vaccine-induced antibody levels. Accumulated antibiotic courses up to booster immunization was associated with decreased vaccine antibody levels both before and after booster, suggesting that booster immunization was not sufficient to change the negative association with antibiotic exposure. The results were similar for all vaccines tested, suggesting that the specific vaccine formulation was not a factor.
The study has several limitations. The antibiotic prescription data and measurements of vaccine-induced antibody levels were recorded and measured prospectively; however, our analysis was done retrospectively. The group of study children was derived from my private practice in Rochester, N.Y., and may not be broadly representative of all children. The number of vaccine antibody measurements was limited by serum availability at some sampling time points in some children; and sometimes, the serum samples were collected far apart, which weakened our ability to perform longitudinal analyses. We did not collect stool samples from the children so we could not directly study the effect of antibiotic courses on the gut microbiome.
Our study adds new reasons to be cautious about overprescribing antibiotics on an individual child basis because an adverse effect extends to reduction in vaccine responses. This should be explained to parents requesting unnecessary antibiotics for colds and coughs. When antibiotics are necessary, the judicious choice of a narrow-spectrum antibiotic or a shorter duration of a broader spectrum antibiotic may reduce adverse effects on vaccine-induced immunity.

In this column I have previously discussed the microbiome and its importance to health, especially as it relates to infections in children. Given the appreciated connection between microbiome and immunity, my group in Rochester, N.Y., recently undertook a study of the effect of antibiotic usage on the immune response to routine early childhood vaccines. In mouse models, it was previously shown that antibiotic exposure induced a reduction in the abundance and diversity of gut microbiota that in turn negatively affected the generation and maintenance of vaccine-induced immunity.1,2 A study from Stanford University was the first experimental human trial of antibiotic effects on vaccine responses. Adult volunteers were given an antibiotic or not before seasonal influenza vaccination and the researchers identified specific bacteria in the gut that were reduced by the antibiotics given. Those normal bacteria in the gut microbiome were shown to provide positive immunity signals to the systemic immune system that potentiated vaccine responses.3
My group conducted the first-ever study in children to explore whether an association existed between antibiotic use and vaccine-induced antibody levels. In the May issue of Pediatrics we report results from 560 children studied.4 From these children, 11,888 serum antibody levels to vaccine antigens were measured. Vaccine-induced antibody levels were determined at various time points after primary vaccination at child age 2, 4, and 6 months and boosters at age 12-18 months for 10 antigens included in four vaccines: DTaP, Hib, IPV, and PCV. The antibody levels to vaccine components were measured to DTaP (diphtheria toxoid, pertussis toxoid, tetanus toxoid, pertactin, and filamentous hemagglutinin), Hib conjugate (polyribosylribitol phosphate), IPV (polio 2), and PCV (serotypes 6B, 14, and 23F). A total of 342 children with 1,678 antibiotic courses prescribed were compared with 218 children with no antibiotic exposures. The predominant antibiotics prescribed were amoxicillin, cefdinir, amoxicillin/clavulanate, and ceftriaxone, since most treatments were for acute otitis media.
Of possible high clinical relevance, we found that from 9 to 24 months of age, children with antibiotic exposure had a higher frequency of vaccine-induced antibody levels below protection compared with children with no antibiotic use, placing them at risk of contracting a vaccine-preventable infection for DTaP antigens DT, TT, and PT and for PCV serotype 14.
For time points where antibody levels were determined within 30 days of completion of a course of antibiotics (recent antibiotic use), individual antibiotics were analyzed for effect on antibody levels below protective levels. Across all vaccine antigens measured, we found that all antibiotics had a negative effect on antibody levels and percentage of children achieving the protective antibody level threshold. Amoxicillin use had a lower association with lower antibody levels than the broader spectrum antibiotics, amoxicillin clavulanate (Augmentin), cefdinir, and ceftriaxone. For children receiving amoxicillin/clavulanate prescriptions, it was possible to compare the effect of shorter versus longer courses and we found that a 5-day course was associated with subprotective antibody levels similar to 10 days of amoxicillin, whereas 10-day amoxicillin/clavulanate was associated with higher frequency of children having subprotective antibody levels (Figure).
We examined whether accumulation of antibiotic courses in the first year of life had an association with subsequent vaccine-induced antibody levels and found that each antibiotic prescription was associated with a reduction in the median antibody level. For DTaP, each prescription was associated with 5.8% drop in antibody level to the vaccine components. For Hib the drop was 6.8%, IPV was 11.3%, and PCV was 10.4% – all statistically significant. To determine if booster vaccination influenced this association, a second analysis was performed using antibiotic prescriptions up to 15 months of age. We found each antibiotic prescription was associated with a reduction in median vaccine-induced antibody levels for DTaP by 18%, Hib by 21%, IPV by 19%, and PCV by 12% – all statistically significant.
Our study is the first in young children during the early age window where vaccine-induced immunity is established. Antibiotic use was associated with increased frequency of subprotective antibody levels for several vaccines used in children up to 2 years of age. The lower antibody levels could leave children vulnerable to vaccine preventable diseases. Perhaps outbreaks of vaccine-preventable diseases, such as pertussis, may be a consequence of multiple courses of antibiotics suppressing vaccine-induced immunity.
A goal of this study was to explore potential acute and long-term effects of antibiotic exposure on vaccine-induced antibody levels. Accumulated antibiotic courses up to booster immunization was associated with decreased vaccine antibody levels both before and after booster, suggesting that booster immunization was not sufficient to change the negative association with antibiotic exposure. The results were similar for all vaccines tested, suggesting that the specific vaccine formulation was not a factor.
The study has several limitations. The antibiotic prescription data and measurements of vaccine-induced antibody levels were recorded and measured prospectively; however, our analysis was done retrospectively. The group of study children was derived from my private practice in Rochester, N.Y., and may not be broadly representative of all children. The number of vaccine antibody measurements was limited by serum availability at some sampling time points in some children; and sometimes, the serum samples were collected far apart, which weakened our ability to perform longitudinal analyses.
