Early Sensorimotor Skill Differences can Guide Autism Diagnosis

On By ModernMedia

New research published in the journal iSCIENCE has revealed new insights into early sensorimotor features and cognitive abilities of toddlers who are later diagnosed with Autism Spectrum Disorder (ASD). The research, led by Kristina Denisova, a professor of Psychology and Neuroscience at the CUNY Graduate Center and Queens College, takes an important step toward better understanding ASD so that more precise, individually tailored interventions can be developed.

ASD, typically diagnosed around the ages of 4 to 5 years, is a neurodevelopmental disorder with complex and varied presentations, including atypical communication and restrictive and repetitive patterns of behaviour. Moreover, cognitive abilities are often lower in individuals with ASD. Despite the established link between lower intelligence quotient (IQ) in infancy and a future diagnosis of ASD, not all children with ASD exhibit lower cognitive abilities during infancy. The study addresses the critical gap in knowledge regarding the early features that differentiate children with varying cognitive abilities who later develop ASD.

The research team investigated the relationship between movement and cognitive abilities in toddlers before their ASD diagnosis, both during sleep and wakefulness. The study posed two key questions: Do ASD children with lower IQ exhibit altered movement during sleep compared to children with higher IQ? Additionally, are lower motor skills during wakefulness characteristic of lower-IQ children with ASD compared to those of higher-IQ ASD toddlers?

The research was conducted in two stages. In the first sample, the team examined sensorimotor features obtained from sleep functional magnetic resonance imaging (fMRI) in 111 toddlers with ASD. In the second, independent sample, they analysed sensorimotor functioning during wakefulness in over 1000 toddlers with ASD, categorised by lower vs higher cognitive abilities.

The findings revealed that toddlers with ASD and lower IQs have significantly altered sensorimotor features compared to toddlers with ASD and higher IQs. Interestingly, the sensorimotor features of higher-IQ ASD toddlers were nearly indistinguishable from typically developing (TD) toddlers. This suggests that a higher IQ may confer resilience to atypical sensorimotor functioning, and conversely, that poor sensorimotor functioning may be a key marker for lower IQ in childhood autism.

Moreover, the study found that lower-IQ ASD toddlers consistently exhibited lower gross motor skills across various age milestones (6, 12, 18, 24, and 30 months). This disruption in early sensorimotor learning during critical developmental periods indicates a potential vulnerability in the brain’s motor control circuitry, associated with lower cognitive abilities in toddlers who later receive an ASD diagnosis.

“The implications of these findings are far-reaching,” said Denisova. “They underscore the need for more precise, tailored interventions for children with ASD, particularly those with lower cognitive abilities. Interventions for lower-IQ autistic children may need to focus on enhancing both sensorimotor and cognitive skills, while interventions for higher-IQ autistic children might prioritise leveraging their strengths to mitigate potential mental health consequences.”

Denisova emphasised the importance of future research in this area, particularly involving underserved families who face barriers in accessing early intervention services.

Health and Economic Benefits of Breastfeeding Quantified

Breastmilk can promote equitable child health and save healthcare costs by reducing childhood illnesses and healthcare utilisation in the early years, according to a new study published this week in the open-access journal PLOS ONE by Tomi Ajetunmobi of the Glasgow Centre for Population Health, Scotland, and colleagues.

Breastfeeding has previously been found to promote development and prevent disease among infants. In Scotland – as well as other developed countries – low rates of breastfeeding in more economically deprived areas are thought to contribute to inequalities in early childhood health. However, government policies to promote child health have made little progress and more evidence on the effectiveness of interventions may be needed.

In the new study, researchers used administrative datasets on 502,948 babies born in Scotland between 1997 and 2009. Data were available on whether or not infants were breastfed during the first 6-8 weeks, the occurrence of ten common childhood conditions from birth to 27 months, and the details of hospital admissions, primary care consultations and prescriptions.

Among all infants included in the study, 27% were exclusively breastfed, 9% mixed fed and 64% formula fed during the first 6-8 weeks of life. The rates of exclusively breastfed infants ranged from 45% in the least deprived areas to 13% in the most deprived areas.

The researchers found that, within each quintile of deprivation, exclusively breastfed infants used fewer healthcare services and incurred lower costs compared to infants fed any formula milk. On average, breastfed infants had lower average costs of hospital care per admission (£42) compared to formula-fed infants (£79) in the first six months of life and fewer GP consultations (1.72, 95% CI: 1.66 – 1.79) than formula-fed infants (1.92 95% CI: 1.88 – 1.94). At least £10 million of healthcare costs could have been avoided if all formula-fed infants had instead been exclusively breastfed for the first 6-8 weeks of life, the researchers calculated.

The authors conclude that breastfeeding has a significant health and economic benefit and that increasing breastfeeding rates in the most deprived areas could contribute to the narrowing of inequalities in the early years.

Giving Fizzy Drinks to Toddlers Increases Adult Obesity Risk

On By ModernMedia

Consuming sugar-sweetened drinks in the first few years of childhood can be linked to poor diet patterns that increase the risk of obesity in later life, according to a new study by the School of Psychology at Swansea University.

Published in the European Journal of Clinical Nutrition, the study tracked the influence of diet on 14 000 British children from birth to adulthood and is believed to be the longest of its kind ever reported.

Using the Avon Longitudinal Study of Parents and Children, the research team found:

  • Children who drank fizzy drinks such as cola or sugar-sweetened fruit cordials before the age of two gained more weight when they were 24 years old. Girls who had pure fruit juice gained less weight, while the weight of boys remained the same.
  • At three years of age, toddlers who drank cola consumed more calories, fat, protein, and sugar but less fibre. In contrast, those given pure apple juice consumed less fat and sugar but higher amounts of fibre.

The study also highlighted corresponding differences in food choices.

Children who consumed pure apple juice often followed a diet with more fish, fruit, green vegetables, and salad, whereas those drinking cola ate more burgers, sausages, pizza, french fries, meat, chocolate, and sweets.

Additionally, the team discovered a link between sugar-sweetened drinks and social deprivation, with children from affluent backgrounds more likely to have access to pure fruit juice.

Lead researcher Professor David Benton said: “The early diet establishes a food pattern that influences, throughout life, whether weight increases. The important challenge is to ensure that a child develops a good dietary habit: one that offers less fat and sugar, although pure fruit juice, one of your five a day, adds vitamin C, potassium, folate, and plant polyphenols.”

Dr Hayley Young added: “Obesity is a serious health concern, one that increases the risk of many other conditions. Our study shows that the dietary causes of adult obesity begin in early childhood and that if we are to control it, more attention needs to be given to our diet in the first years of life.”

Study Finds Screen Time for Toddlers is a Bad Idea

On By ModernMedia

Babies and toddlers exposed to television or video viewing may be more likely to exhibit atypical sensory behaviours, such as being disengaged and disinterested in activities, seeking more intense stimulation in an environment, or being overwhelmed by sensations like loud sounds or bright lights, according to data from researchers at Drexel’s College of Medicine published in the journal JAMA Pediatrics.

According to the researchers, children exposed to greater TV viewing by their second birthday were more likely to develop atypical sensory processing behaviours, such as “sensation seeking” and “sensation avoiding,” as well as “low registration” – being less sensitive or slower to respond to stimuli, such as their name being called, by 33 months old.

Sensory processing skills reflect the body’s ability to respond efficiently and appropriately to information and stimuli received by its sensory systems, such as what the toddler hears, sees, touches, and tastes.

The team pulled 2011-2014 data on television or DVD-watching by babies and toddlers at 12- 18- and 24-months from the National Children’s Study of 1471 children (50% male) nationwide.

Sensory processing outcomes were assessed at 33 months using the Infant/Toddler Sensory Profile (ITSP), a questionnaire completed by parents/caregivers, designed to give insights on how children process what they see, hear and smell, etc.

ITSP subscales examine children’s patterns of low registration, sensation seeking, such as excessively touching or smelling objects; sensory sensitivity, such as being overly upset or irritated by lights and noise; and sensation avoiding – actively trying to control their environment to avoid things like having their teeth brushed. Children score in “typical,” “high” or “low” groups based on how often they display various sensory-related behaviours. Scores were considered “typical” if they were within one standard deviation from the average of the ITSP norm.

Measurements of screen exposure at 12-months were based on caregiver responses to the question: “Does your child watch TV and/or DVDs? (yes/no),” and at 18- and 24- months based on the question: “Over the past 30 days, on average, how many hours per day did your child watch TV and/or DVDs?”

The findings suggest:

  • At 12 months, any screen exposure compared to no screen viewing was associated with a 105% greater likelihood of exhibiting “high” sensory behaviours instead of “typical” sensory behaviours related to low registration at 33 months
  • At 18 months, each additional hour of daily screen time was associated with 23% increased odds of exhibiting “high” sensory behaviours related to later sensation avoiding and low registration.
  • At 24 months, each additional hour of daily screen time was associated with a 20% increased odds of “high” sensation seeking, sensory sensitivity, and sensation avoiding at 33 months.

The researchers adjusted for age, whether the child was born prematurely, caregiver education, race/ethnicity and other factors, such as how often the child engages in play or walks with the caregiver.

The findings add to a growing list of concerning health and developmental outcomes linked to screen time in infants and toddlers, including language delay, autism spectrum disorder, behavioural issues, sleep struggles, attention problems and problem-solving delays.

“This association could have important implications for attention deficit hyperactivity disorder and autism, as atypical sensory processing is much more prevalent in these populations,” said lead author Karen Heffler, MD, an associate professor of Psychiatry in Drexel’s College of Medicine. “Repetitive behaviour, such as that seen in autism spectrum disorder, is highly correlated with atypical sensory processing. Future work may determine whether early life screen time could fuel the sensory brain hyperconnectivity seen in autism spectrum disorders, such as heightened brain responses to sensory stimulation.”

Atypical sensory processing in kids with autism spectrum disorder (ASD) and ADHD manifests in a range of detrimental behaviours. In children with ASD, greater sensation seeking or sensation avoiding, heightened sensory sensitivity and low registration have been associated with irritability, hyperactivity, eating and sleeping struggles, as well as social problems. In kids with ADHD, atypical sensory processing is linked to trouble with executive function, anxiety and lower quality of life.

“Considering this link between high screen time and a growing list of developmental and behavioural problems, it may be beneficial for toddlers exhibiting these symptoms to undergo a period of screen time reduction, along with sensory processing practices delivered by occupational therapists,” said Heffler.

The American Academy of Pediatrics (AAP) discourages screen time for babies under 18–24 months. Live video chat is considered by the AAP to be okay, as there may be benefit from the interaction that takes place. AAP recommends time limitations on digital media use for children ages two to five years to typically no more than one hour per day.

“Parent training and education are key to minimising, or hopefully even avoiding, screen time in children younger than two years,” said senior author David Bennett, PhD, a professor of Psychiatry in Drexel’s College of Medicine.

Early Cleft Palate Surgery Yields Better Speech Results

On By ModernMedia

According to a new international study published in the New England Journal of Medicine, cleft palate surgery at the age of six months provides better conditions for speech and language development compared to surgery at 12 months.

Isolated cleft palate is a congenital condition where the palate is not closed and there is an opening between the mouth and the nose. The condition occurs in 1 to 25 per 10 000 births worldwide.

“There has previously been limited evidence for the optimal age for cleft palate surgery in children to achieve the best results”, says Anette Lohmander, professor emeritus at at Karolinska Institutet and principal investigator for the Stockholm centre in the study.

The study, by researchers from Karolinska Institutet and Karolinska University Hospital, among others, involved 558 children from 23 different centres around Europe and South America. Of these, 235 children were randomly assigned to a group to undergo surgery at six months of age and 226 children were randomly assigned to undergo surgery at twelve months of age.

Speech-language therapists/pathologists performed standardised audio-video recordings at one, three and five years of age. The researchers then evaluated the children’s babbling, velopharyngeal function, and speech.

At age five, the researchers found insufficient velopharyngeal function in 21 children (8.9%) who had surgery at six months of age compared with 34 children (15%) who had surgery at age 12 months.

Complications resulting from surgery were rare in both groups. Four serious adverse events were reported but were resolved on follow-up.

The conclusion of the study was that velopharyngeal function for speech at five years was better in the children who had undergone surgery at six months of age than in those who had undergone surgery at 12 months of age. Risks associated with earlier repair may include maxillary arch constriction and the need for secondary surgery for velopharyngeal insufficiency.

“An additional advantage of the early surgery age was a higher incidence of canonical syllables. It is a milestone in children’s language development and is established in typically developed children by the age of ten months at the latest,” says Anette Lohmander, who continues. “The children included in the study had no developmental delay or other deviant conditions. The conclusion is that when it is possible to operate on the cleft palate early, it seems to provide the best conditions for speech and language development.”

Adding Complex Milk Component to Infant Formula Confers Long-term Cognitive Benefits

On By ModernMedia

Breastfeeding in infancy has been shown to confer cognitive and health benefits. For decades, researchers have sought to create a viable complement or alternative to breast milk to give children their best start for healthy development. New research out of the University of Kansas and published in the Journal of Pediatrics has shown how a complex component of milk that can be added to infant formula has been shown to confer long-term cognitive benefits, including measures of intelligence and executive function in children.

The research by John Colombo, KU Life Span Institute director and investigator, along with colleagues at Mead Johnson Nutrition and in Shanghai, China, adds to the growing scientific support for the importance of ingredients found in milk fat globule membrane (MFGM) in early human development.

The study showed that feeding infants formula supplemented with MFGM and lactoferrin for 12 months raised IQ by 5 points at 5 ½ years of age. The effects were most evident in tests of children’s speed of processing information and visual-spatial skills. Significant differences were also seen in children’s performance on tests of executive function, which are complex skills involving rule learning and inhibition.

All forms of mammalian milk contain large fat globules that are surrounded by a membrane composed of a variety of nutrients important to human nutrition and brain development, Colombo said. When milk-based infant formula is manufactured, the membrane has typically been removed during processing.

“No one thought much about this membrane,” Colombo said, “until chemical analyses showed that it’s remarkably complex and full of components that potentially contribute to health and brain development.”

The 2023 study was a follow-up to a 2019 one also published in the Journal of Pediatrics, which showed that babies who were fed formula with added bovine MFGM and lactoferrin had higher scores on neurodevelopmental tests during the first year and on some aspects of language at 18 months of age.

The global nutrition research community has been looking at MFGM for about a decade, Colombo said. Because the membrane is made up of several different components, it isn’t known whether one of the components is responsible for these benefits, or whether the entire package of nutrients act together to improve brain and behavioural development.

These benefits were seen in children long after the end of formula feeding at 12 months of age.

“This is consistent with the idea that early exposure to these nutritional components contribute to the long-term structure and function of the brain,” said Colombo, who has spent much of his career researching the importance of early experience in shaping later development.

How Mother and Infant Sleep Cycles Interact

On By ModernMedia

New mothers can expect sleep deprivation in the first few years of baby’s life. But too little sleep can take a toll on the health of both mother and child. Published in Journal of Developmental & Behavioral Pediatrics, a new study from at maternal and infant sleep patterns, identifying predictors and providing recommendations for instilling healthy habits, such as earlier bedtimes and instilling routines.

“The first two years is a really critical period where a lot of development is going on, and sleep is important for health. We wanted to look at the association of mother and infant sleep and whether it changes over time,” said Tianying Cai, now a postdoctoral researcher at Northwestern University.

“We identified two distinct groups, a low maternal sleep group where the mothers get 5 to 6 hours of sleep per night, and an average maternal sleep group, which meets the national recommended sleep guidelines with 7 to 8 hours per night. Children in the low maternal sleep group also slept less, although the difference wasn’t as large as for the mothers,” Cai stated.

Researchers from the University of Illinois Urbana-Champaign followed parents of 464 infants in the first two years of life. Mothers completed surveys about bedtime routines, their child’s sleep duration, night-time waking, and sleep problems at 3, 12, 18, and 24 months of age.

The families were part of STRONG Kids 2, a program at the U. of I. that promotes nutrition and healthy habits in families with young children. STRONG Kids 2 co-directors Barbara Fiese, professor emerita of HDFS, and Sharon Donovan, professor of food science and human nutrition, also contributed to the study.

Mothers who fit the low maternal sleep profile got an average of 5.74 hours of sleep per night at 3 months and 5.9 hours at 12 to 24 months, while their children got 9.6 and 10.52 hours, respectively. In the average sleep profile, mothers got 7.31 hours at 3 months and 7.28 hours at 12 to 24 months, while child sleep averaged 9.99 hours at 3 months and 11 hours at 12 to 24 months.

The research team also identified factors that influence the amount of sleep a mother gets. Not surprisingly, one of the strongest predictors is infant-signalled night-time waking, which means the infant is more likely to alert the parent at night. This could be either because these infants woke more frequently, or because the mothers were more likely to wake up when infants stirred, Cai noted.

Mothers who had longer employment hours were more likely to be in the low sleep group at 3 months, although that was no longer a factor by 12 months. Furthermore, those who breastfed their infant at 12 months were more likely to be in the average sleep group.

Over time, many families transitioned from the low to the average sleep group as infant sleep patterns consolidated. At 3 months, 60% were in the low maternal sleep group and 40% were in the average group, while at 12 months the numbers were reversed. Most of those who were in the average sleep group at 3 months continued to be so throughout the study period.

The researchers found that an earlier bedtime and consistent routines were associated with better sleep patterns, corroborating a previous study from Fiese and Cai.

“If parents can establish early bedtime routines at three months, it improves sleep duration and reduces sleep problems,” Fiese said. “Parents may feel overwhelmed and don’t realise that they have this in their toolkit. Something as simple as setting a regular bedtime early on and having routines, like reading a story to your child before they go to bed. You may not think they’re understanding, but the rhythm of your voice establishes predictability, and you can expand this bedtime routine over the first few years of life.”

The researchers noted they did not observe any significant differences due to demographic characteristics in the sample.

“Maternal education, income, or ethnicity did not predict sleep group memberships across 3 to 24 months; all parents were facing similar challenges. I think having a baby is a great equaliser for a lot of things, although moms who have to go back to work or work longer hours may have more pressures,” Donovan said.

Even so, there are steps everyone can take to improve bedtime habits and sleep patterns.

“Getting kids to bed earlier and trying to meet the American Academy of Pediatrics guidelines is really important because studies have shown that sleep is associated with a lot of neurocognitive outcomes and health in kids. The parents can be quite proactive even early in life to get their kids off on the right foot,” she concluded.

Oxygen Deficiency in Newborns may Increase Later Cardiovascular Risk

On By ModernMedia

A population-based observational study has shown that babies suffering oxygen-deficiency complications at birth are almost twice as likely to develop cardiovascular disease in childhood or early adulthood, though such conditions are rare in youth. The findings are published in the journal The Lancet Regional Health – Europe.

According to the Karolinska Institutet researchers, the study could be the first of its kind to examine how complications related to asphyxiation at birth, which affects four million babies annually, affects the risk of cardiovascular disease later in life. Previous research has mostly concentrated on the association between asphyxia in the neonatal period and brain development.

Despite the relatively high risk, the absolute number of babies who suffer from cardiovascular disease despite asphyxiation at birth is very low. After the 30-year follow-up period, only 0.3% of those with asphyxia-related complications had a cardiovascular diagnosis, compared with 0.15% of those without complications.

Since the study was observational, the researchers are unable to establish any causality or propose any underlying mechanisms.

Largest risk increase for stroke and heart failure

The study followed over 2.8 million individuals born in Sweden between 1988 and 2018, of whom 31 419 suffered asphyxia-related complications at birth. A total of 4165 cases of cardiovascular disease were identified during the follow-up period. The increase in risk was particularly salient for stroke and heart failure, as well as for atrial fibrillation. The researchers took into account potential confounders such as birth weight and maternal lifestyle.

“Even if the absolute risk of cardiovascular disease is low at a young age, our study shows that asphyxia-related complications at birth are associated with a higher risk of cardiovascular disease later in life,” says the study’s corresponding author Neda Razaz, assistant professor at the Department of Medicine, Solna, Karolinska Institutet.

Diarrhoea in Infants Requires Urgent Attention

On By ModernMedia

Diarrhoea remains one of the leading causes of death, ill health and disability among children under five years of age in developing countries,1 accounting for 19% of deaths of under-fives in South Africa and for 46% on the African continent.1 Globally, diarrhoea is the second leading infectious cause of death, accounting for 9.2% of deaths in under-fives.1

The high incidence of malnutrition in South Africa2 adds to this toll. The relationship between diarrhoea and malnutrition is bidirectional: diarrhoea may lead to malnutrition, while malnutrition may aggravate the course of diarrhoea.3 Diarrhoea is more common and more severe in children with malnutrition (ie, undernutrition), and malnourished children often have persistent or repeated diarrhoea.4 In addition, malnourished children are more likely to develop severe diarrhoea and die from it.4 Vulnerable groups such as pregnant women and children under five years of age are the most affected by malnutrition, especially in rural areas.5

Identifying children at risk

The Centres for Disease Control advises that caregivers should be trained to recognise signs of illness or treatment failure that necessitate medical intervention.6 Infants with acute diarrhoea are more prone to becoming dehydrated than older children,6 and healthcare workers or parents of infants with diarrhoea should promptly seek medical evaluation as soon as the child appears to be in distress. Reports of changing mental status in the child are of particular concern.6

When the child’s condition is in doubt, immediate evaluation by a healthcare professional is recommended.6 Clinical examination of the child provides an opportunity for physical assessment, including vital signs, degree of dehydration, and a more detailed history, and for providing better instructions to the caregivers.6

Treatment

The treatment emphasis for acute diarrhoea in children is the prevention and management of dehydration, electrolyte abnormalities and comorbid conditions.3 The objectives of diarrhoeal disease management are to prevent weight loss, encourage catch-up growth during recovery, shorten the duration and decrease the impact of the diarrhoea on the child’s health.3

A number of studies have shown that probiotics shorten the duration of diarrhoea and prevent recurrence of other episodes.7 Furthermore, probiotics can prevent diarrhoea from infection in infants with malnutrition.7

Momeena Omarjee, Consumer Healthcare Country Head: Scientific Affairs, at Sanofi South Africa says: “Good gut health is crucial for one’s wellbeing – and healthcare professionals should encourage parents to give children a daily, regular probiotic which could go a long way in preventing diarrhoea and illness.”

How can the risk of diarrhoea be reduced?

Breastfeeding, a clean safe water supply, appropriate hand-washing and good sanitation will prevent most cases of diarrhoea.8

Research shows that diarrhoea is closely linked to socioeconomic status and has the most adverse effects in South Africa’s impoverished communities.9 South African children living in poverty are approximately 10 times more likely to die from diarrhoea than their more privileged counterparts.9

Says Omarjee: “Many of these under-privileged children in South Africa do not have adequate access to clean, potable water and quality early childcare and development, and they experience limited access to health and nutrition services. KwaZulu-Natal (KZN), for example, is experiencing outbreaks of diarrhoea and other water-borne diseases due to the recent floods.”

Although government and NGOs have been working tirelessly to distribute clean, potable water to affected areas in the province, many communities continue to face challenges and intervention is needed to not only provide clean water to the communities, but also to manage the high risk of diarrhoea and related water-borne diseases.

“Sanofi has therefore embarked on an ambitious campaign, in partnership with a non-profit organisation, Save the Children South Africa, from October 2022 to assist these areas in need, and to impact over 2,000,000 lives through hygiene education and access to water,” says Omarjee.

Sanofi, working together with Save the children South Africa, will donate water tanks to Early Childhood Care and Development (ECCD) centres in the communities identified, based on Save the Children’s baseline assessment, and will ensure access to clean, potable water.

The provision of information, counselling, education and support to children and their caregivers is also limited, which translates into low use of services and uptake of practices promoting good health. Education campaigns on healthy hygiene habits will be rolled out to children and their caregivers and will be run through the Child Health Awareness Days (CHAD) events, training of ECCD centres practitioners, and community health workers.

Sanofi is committed to ensuring that no child dies of a preventable disease, especially when there are effective treatments available. Says Omarjee: “Healthcare professionals need to encourage parents and caregivers to act promptly and seek assistance when instances of diarrhoea in children under age five do not abate swiftly.”

Azithromycin in Infant RSV Does Not Prevent Wheezing, May be Harmful

On By ModernMedia
Photo by William-Fortunato on Pexels

A recent study on the impact of the antibiotic azithromycin during severe respiratory syncytial virus (RSV) bronchiolitis overwhelmingly supports current bronchiolitis guidelines in the US, which recommend against antibiotics during acute bronchiolitis.

The anti-inflammatory properties of azithromycin can be beneficial in some chronic lung diseases, such as cystic fibrosis. With that in mind, researchers investigated its potential to prevent future recurrent wheezing among infants hospitalised with RSV. With such babies at increased risk of developing asthma later in childhood, the scientists hoped to find a therapy to reduce this risk.

The study, published in NEJM Evidence, also provided considerable evidence that severe RSV bronchiolitis in early life increases the likelihood of repeated wheezing episodes in early childhood, often leading to asthma.

“The major message is that antibiotics don’t have a role, either in the management of acute RSV bronchiolitis or to reduce subsequent wheezing,” said co-corresponding author Leonard Bacharier, MD, professor of Pediatrics at Monroe Carell Jr Children’s Hospital at Vanderbilt. “As a matter of fact, we found that antibiotics in general in our study of severe RSV bronchiolitis increased the risk of subsequent recurrent wheezing over the following two to four years.”

“We need to discourage the use of this therapy, as it is potentially harmful,” he said.

The study examined children hospitalised with RSV bronchiolitis during a single-center, double-blind, placebo-controlled trial.

An earlier pilot trial enrolled 40 infants hospitalised with RSV bronchiolitis where treatment with azithromycin, and this showed a reduction in the likelihood of recurrent wheeze over the following year.

In the current study, 200 otherwise healthy 1- to 18-month-old children who were hospitalised for RSV bronchiolitis were prospectively randomised to either oral azithromycin or a placebo for 14 days. The group was broadly representative of the population of children who experience severe RSV bronchiolitis.

Antibiotics are sometimes used in the treatment of RSV because co-occurring complications lead medical teams to prescribe them, thinking there is a bacterial component to the illness, Prof Bacharier said.
“This condition can be managed by supportive care – oxygen, fluids, observation, time and love,” he stressed. “If a clinician is going to use an antibiotic in the setting of RSV bronchiolitis, there needs to be a very strong rationale for doing so. There is substantial evidence to suggest that children who receive antibiotics early in life are at an increased risk of developing asthma, and this study is consistent with that evidence.”
