Diarrhoea in Infants Requires Urgent Attention

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

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.”

Sleep is Also Important in Avoiding Overweight in Babies

While the importance has long been known, little research has examined the necessity of sufficient sleep during the first months of life. New research suggests that newborns who sleep longer and wake up less throughout the night are less likely to be overweight in infancy. Their results are published in Sleep.

“While an association between insufficient sleep and weight gain is well-established in adults and older children, this link has not been previously recognized in infants,” said study co-author Susan Redline, MD, MPH, senior physician in the Division of Sleep and Circadian Disorders at the Brigham. “In this study, we found that not only shorter nighttime sleep, but more sleep awakenings, were associated with a higher likelihood of infants becoming overweight in the first six months of life.”

To conduct this research, Dr Redline and colleagues observed 298 newborns born at Massachusetts General Hospital between 2016 and 2018. The infants’ sleep patterns were monitored using ankle actigraphy watches – devices that measure patterns of activity and rest over multiple days. Researchers obtained three nights’ worth of data at the one- and six-month marks while parents kept sleep diaries, recording their children’s sleep and wake episodes.

Scientists measured infant height and weight and determined their body mass index, classifying infants as overweight if they fell into or above the 95th percentile on the World Health Organization’s growth charts.

Notably, researchers found that just one extra hour of sleep was associated with a 26% decrease in overweight risk. Additionally, infants that woke up less during the night faced a lower risk of excess weight gain. Scientists speculate that having more sleep promotes routine feeding practices and self-regulation, factors that mitigate overeating.

Investigators noted an underrepresentation of African-American individuals and lower-income families in their dataset. Additionally, confounding variables, such as breastfeeding duration, could have impacted infant growth. In the future, the researchers aim to extend this study to evaluate how sleep patterns impact growth within the first two years of life and identify key factors that mediate the correlation between sleep and weight gain. They also aim to evaluate interventions for promoting healthy sleep habits.

“This study underscores the importance of healthy sleep at all ages,” said Dr Redline. “Parents should consult their pediatricians on the best practices to promote healthy sleep, like keeping consistent sleep schedules, providing a dark and quiet space for sleeping, and avoiding having bottles in bed.”

Mothers’ Touch Synchronises Brainwaves and Heart With Babies

On By ModernMedia

A new study found that when mothers had close physical contact and played with their babies, their brain activity and heart rhythms synchronised.

Touch is fundamental to interpersonal communication, and was not until recently it was not known how affectionate touch and physical contact affect the brain activity and heart rhythms of mothers and babies. Developmental psychologists Trinh Nguyen and Stefanie Höhl from the University of Vienna have investigated this question in a study published in NeuroImage. 

Affectionate touch and bodily contact create social connections and can reduce stress. This effect has been observed in romantic couples, linked to a mutual alignment of brain activity and heart rhythms.  Since touch is a fundamental mode of communication between caregiver and infant, Trinh Nguyen, Stefanie Höhl and US colleagues sought to find out whether proximity and touch also contribute to the attunement of brain and heart rhythms between mother and baby.

In the new study, four to six-month-old babies played and watched videos together with their mothers. Functional near-infrared spectroscopy (fNIRS) was used to measure brain activity while electrocardiography (ECG) was used to simultaneously assess the heart rhythms of mother and baby. With fNIRS, changes in oxygen saturation are recorded in the outermost layer of the brain – here in particular in the frontal brain. Activation in this region is associated with mutual emotional attunement, attentiveness and self-regulation. These processes are particularly relevant for social interactions and develop during the first years.

The results showed that mother-baby pairs mutually adjusted their brain activity, especially when they touched each other. Mutual neural adjustment occurred when the mother held the baby close to her body and both watched a video together, and when they played together face-to-face and the mother lovingly touched the baby. The new study shows that touch plays a fundamental role in the early adaptation of brain activity between mothers and infants. An adaptation of heart rhythms was also shown when mother and baby played together, but it was independent of touch. In the case of the heartbeat, a mutual adaptation was particularly evident when babies signalled discomfort, which was presumably transmitted to the mothers.

The researchers next want to investigate how this mutual attunement in brain activity and heart rhythms affects long term development, particularly the later relationship between mother and child, as well as children’s language development.
