Study finds children can become seriously ill with COVID-19

May 14, 2020

Despite early reports suggesting COVID-19 does not seriously impact children, a new study shows that children who contract COVID-19 can become very ill.

In contrast to the prevailing view that the novel coronavirus known as COVID-19 does not seriously impact children, a new study finds that children who contract the virus can become very ill—many of them critically so, according to physician researchers at Children’s National Hospital. Their results, published in the Journal of Pediatrics and among the first reports from a U.S. institution caring for children and young adults, shows differences in the characteristics of children who recovered at home, were hospitalized, or who required life support measures. These findings highlight the spectrum of illness in children, and could help doctors and parents better predict which pediatric patients are more likely to become severely ill as a consequence of the virus.

In late 2019, researchers identified a new coronavirus, known as SARS-CoV-2, which causes COVID-19. As the disease spread around the world, the vast majority of reports suggested that elderly patients bear the vast majority of the disease burden and that children are at less risk for either infection or severe disease. However, study leader Roberta DeBiasi, M.D., M.S., chief of the Division of Infectious Diseases at Children’s National, states that she and her colleagues began noticing an influx of children coming to the hospital for evaluation of a range of symptoms starting in mid-March 2020, who were tested and determined to be infected with COVID-19. One quarter of these children required hospitalization or life support.

“It was very apparent to us within the first several weeks of the epidemic that this was a very different situation than our colleagues on the West Coast of the US had described as their experience just weeks before,” DeBiasi says. “Right away, we knew that it was important for us to not only care for these sick children, but to examine the factors causing severe disease, and warn others who provide medical care to children.”

To better understand this phenomenon, she and her colleagues examined the medical records of symptomatic children and young adults who sought treatment at Children’s National for COVID-19 between March 15 and April 30, 2020. Each of these 177 children tested positive using a rapid assay to detect SARS-CoV-2 performed at the hospital. The researchers gathered data on each patient, including demographic details such as age and sex; their symptoms; whether they had any underlying medical conditions; and whether these patients were non-hospitalized, hospitalized, or required critical care.

The results of their analysis show that there was about an even split of male and female patients who tested positive for COVID-19 at Children’s National during this time period. About 25% of these patients required hospitalization. Of those hospitalized, about 75% weren’t considered critically ill and about 25% required life support measures. These included supplemental oxygen delivered by intubation and mechanical ventilation, BiPAP, or high-flow nasal cannula – all treatments that support breathing – as well as other support measures such as dialysis, blood pressure support and medications to treat infection as well as inflammation.

Although patients who were hospitalized spanned the entire age range, more than half of them were either under a year old or more than 15 years old. The children and young adults over 15 years of age, Dr. DeBiasi explains, were more likely to require critical care.

About 39% of all COVID-19 patients had underlying medical conditions, including asthma, which has been highlighted as a risk factor for worse outcomes with this infection. However, DeBiasi says, although underlying conditions were more common as a whole in hospitalized patients – present in about two thirds of hospitalized and 80% of critically ill – asthma didn’t increase the risk of hospitalization or critical illness. On the other hand, children with underlying neurological conditions, such as cerebral palsy, microcephaly, or global developmental delay, as well as those with underlying cardiac, hematologic, or oncologic conditions were significantly more likely to require hospitalization.

In addition, although early reports of COVID-19 suggested that fever and respiratory symptoms are hallmarks of this infection, Dr. DeBiasi and her colleagues found that fewer than half of patients had both concurrently. Those with mild, upper respiratory symptoms, such as runny nose, congestion, and cough were less likely to end up hospitalized than those with more severe respiratory symptoms, such as shortness of breath. The frequency of other symptoms including diarrhea, chest pain and loss of sense of smell or taste was similar among hospitalized and non-hospitalized patients.

Dr. DeBiasi notes that although other East Coast hospitals are anecdotally reporting similar upticks in pediatric COVID-19 patients who become seriously ill, it’s currently unclear what factors might account for differences from the less frequent and milder pediatric illness on the West Coast. Some factors might include a higher East Coast population density, differences between the genetic, racial and ethnic makeup of the two populations, or differences between the viral strains circulating in both regions (an Asian strain on the West Coast, and a European strain on the East Coast).

Regardless, she says, the good news is that the more researchers learn about this viral illness, the better prepared parents, medical personnel and hospitals will be to deal with this ongoing threat.

A bronchopulmonary dysplasia primer to guide clinicians and researchers

February 14, 2020

Six months in the writing, the “Bronchopulmonary Dysplasia Primer” published recently by Nature Reviews will be the gold standard review on this topic for years to come.

The term bronchopulmonary dysplasia, or BPD, was first coined in 1967 to describe a chronic lung disease of preterm newborns after treatment with supplemental oxygen via mechanical ventilation in an effort to save their lives. Back then, infants had 50-50 odds of surviving.

In the intervening years, survival has improved and the characteristics of BPD have evolved. Now, BPD is the most common complication of preterm birth for infants born at fewer than 28 weeks’ gestation, as more and more newborns survive premature birth. Hence, the primer.

“The contributing authors are some of the biggest thinkers on this topic,” says Robin H. Steinhorn, M.D., senior vice president, Center for Hospital-Based Specialties, at Children’s National Hospital and author of the section about BPD diagnosis, screening and prevention. “This document will guide clinical education and investigators in the field of BPD. I anticipate this will be the definitive review article on the subject for the next several years.”

Gestational age and low birth weight remain the most potent predictors of BPD. Some 50,000 extremely low gestational age newborns are born each year in the U.S. About 35% will develop some degree of BPD, according to the primer authors.

These newborns are introduced to life outside the womb well before their lungs are ready. Indeed, the pulmonary surfactants needed for normal lung function – a complex mixture of phospholipids that reduce surface tension within the lungs – don’t differentiate until late in pregnancy. Infants who persistently need respiratory support after the 14^th day of life are at the highest risk of being diagnosed with BPD at 36 weeks, the coauthors note.

A number of complicating factors can come into play, including maternal diet; fetal exposure to maternal smoking and infection; structural issues such as pre-eclampsia; acute injury from mechanical ventilation and supplemental oxygen; as well as the body’s halting efforts to repair injured, inflamed lung tissue.

“The good news is the number of the smallest and youngest preterm infants who survive extreme preterm birth has steadily increased. Neonatal intensive care units, like our award-winning NICU, now routinely care for babies born at 22 weeks’ gestation,” Dr. Steinhorn says.

Treatment strategies include:

Reducing exposure to intubation and ventilation.
Leveraging respiratory stimulants, like caffeine.
Postnatal steroid therapy.

“Children’s National Hospital is the only center in our immediate region that provides comprehensive care for infants and children with severe BPD,” Dr. Steinhorn adds. “As the population of vulnerable and fragile infants has grown, we have invested in the equipment and the personnel – including at the Hospital for Sick Children Pediatric Center (HSC) – to create a very safe and supportive environment that improves survival and quality of life.”

Some preterm infants spend their first 9 to 10 months of life at Children’s National, and their days are filled with concentrated physical, occupational and speech therapy, as well as music and play therapy to hasten their rehabilitation.

Once their medical condition stabilizes, they transition to HSC to focus more intently on rehabilitation.

“We see HSC as filling a very important role in their care. When our children graduate to HSC, they are going for ongoing care of their lung disease, but also their ongoing rehabilitation. At HSC, they focus on creating the most normal life that we can possibly create and, over time, that is a life free of ventilators and tracheostomy tubes.”

Goss, University of Wisconsin-Madison; Matthew Laughon, The University of North Carolina at Chapel Hill; Jeffrey A. Whitsett and Alan H. Jobe, Cincinnati Children’s Hospital Medical Center; Steven H.

Children’s National Hospital: Starting the new year with strong leadership

January 9, 2020

Drs. Tarini, Steinhorn and Beers are also in leadership roles within professional societies, elected by their peers, further highlighting the strength of the leadership at Children’s National and professional respect within the health care community.

Three Children’s National Hospital executives are also in leadership roles within professional societies, elected by their peers, further highlighting the strength of the leadership at Children’s National and professional respect within the health care community.

Lee Savio Beers, M.D., FAAP, medical director of Community Health and Advocacy at the Child Health Advocacy Institute (CHAI) at Children’s National, was elected by her peers to become president-elect of the American Academy of Pediatrics (AAP) beginning Jan. 1, 2020. Dr. Beers will then serve as AAP president in 2021 for a one-year term.

“I am humbled and honored to have the support of my peers in taking on this newest leadership role,” says Dr. Beers. “AAP has been a part of my life since I first became a pediatrician, and my many leadership roles in the DC chapter and national AAP have given me a glimpse of the collective good we pediatricians can accomplish by working together toward common strategic goals.”

Dr. Beers is looking forward to continuing her work bringing together the diverse voices of pediatricians, children and families as well as other organizations to support improving the health of all children.

Robin Steinhorn, M.D., senior vice president of the Center for Hospital-Based Specialties at Children’s National was elected by her peers to become Vice President and President-elect of the American Pediatric Society (APS) in May 2018 and she is currently serving her role as the Society’s president, which began in May 2019.

“This is a tremendous honor. I look forward to leveraging the collective leadership and research accomplishments by our members to improve the health of infants and children throughout the U.S.,” said Dr. Steinhorn.

Dr. Steinhorn is particularly passionate about mentoring faculty and supporting the growth and career development of young neonatologists and scientists, with several having developed their own research laboratories and assumed division and department leadership positions. She was selected as a ‘Top Doctor’ by Northern Virginia Magazine in 2019.

Beth A. Tarini, M.D., MS, associate director, Center for Translational Research at The Children’s Research Institute, became vice president of the Society for Pediatric Research (SPR) in May 2019. Dr. Tarini will transition to President-Elect in May 2020 and become President in May 2021.

Dr. Tarini’s personal mission during this tenure will be to ensure that more pediatric researchers get to know SPR and are so excited about the organization that they become active members.

Dr. Tarini says she looks forward to working with other SPR leaders to find ways to build more productive, collaborative professional networks among faculty, especially emerging junior faculty. “Facilitating ways to network for research and professional reasons across pediatric research is vital – albeit easier said than done. I have been told I’m a connector, so I hope to leverage that skill in this new role,” says Dr. Tarini.

Preserving brain function by purposely inducing strokes

October 17, 2019

Born to young parents, no prenatal testing had suggested any problems with Bella’s brain. But just a few hours after birth, Bella suffered her first seizure – one of many that would follow in the ensuing days. After brain imaging, her doctors in Iowa diagnosed her with hemimegalencephaly.

Strokes are neurologically devastating events, cutting off life-sustaining oxygen to regions of the brain. If these brain tissues are deprived of oxygen long enough, they die, leading to critical loss of function – and sometimes loss of life.

“As physicians, we’re taught to prevent or treat stroke. We’re never taught to inflict it,” says Taeun Chang, M.D., director of the Neonatal Neurology and Neonatal Neurocritical Care Program at Children’s National Hospital.

That’s why a treatment developed at Children’s National for a rare brain condition called hemimegalencephaly is so surprising, Dr. Chang explains. By inflicting controlled, targeted strokes, Children’s National physician-researchers have treated five newborns born with intractable seizures due to hemimegalencephaly before they’re eligible for epilepsy surgery, the standard of care. In the four surviving infants, the procedures drastically reduced or completely relieved the infants of hemimegalencephaly’s characteristic, uncontrollable seizures.

The most recent patient to receive this life-changing procedure is Bella, a 13-month-old from Iowa whose treatment at Children’s National began within her second week of life. Born to young parents, no prenatal testing had suggested any problems with Bella’s brain. But just a few hours after birth, Bella suffered her first seizure – one of many that would follow in the ensuing days. After brain imaging, her doctors in Iowa diagnosed her with hemimegalencephaly.

A congenital condition occurring in just a handful of children born worldwide each year, hemimegalencephaly is marked by one brain hemisphere growing strikingly larger and dysplastic than the other, Dr. Chang explains. This abnormal half of the brain is highly vascularized, rippled with blood vessels needed to support the seizing brain. The most conspicuous symptoms of hemimegalencephaly are the numerous seizures that it causes, sometimes several in the course of an hour, which also may prevent the normal half of the brain from developing and learning.

Prior studies suggest early surgery achieves better developmental outcomes with one study reporting as much as a drop of 10-20 IQ points with every month delay in epilepsy surgery.

The standard treatment for unilateral megalencephaly is a dramatic procedure called a hemispherectomy, in which surgeons remove and disconnect the affected half of the brain, allowing the remaining half to take over its neurological duties. However, Dr. Chang says, implementing this procedure in infants younger than 3 months of age is highly dangerous. Excessive, potentially fatal blood loss is likely in infants younger than 3 months who have a highly vascularized brain in the setting of an immature coagulation system. That leaves their doctors with no choice but to wait until these infants are at least 3 months old, when they are more likely to survive the surgery.

However, five years ago, Dr. Chang and her colleagues came up with a different idea when a newborn continued to have several seizures per hour despite multiple IV seizure medications: Because strokes cause irreversible tissue death, it might be possible to effectively incapacitate the enlarged hemisphere from within by inflicting a stroke on purpose. At the very least, this “functional embolization” might buy time for a traditional hemispherectomy, and slow or halt ongoing brain damage until the infants are able to withstand surgery. Ideally, this procedure may be all some children need, knocking out the offending hemisphere completely so they’d never need a hemispherectomy, which has late complications, such as hydrocephalus.

A pediatrician friend of Bella’s paternal grandparents read a story on Children’s National website about Darcy, another baby who’d received functional embolization a year earlier and was doing well. She contacted Dr. Chang to see if the procedure would be appropriate for Bella.

Within days, Bella and her family headed to Washington, D.C., to prepare for functional embolization herself. Within the first weeks of life, Bella underwent three separate procedures, each three to four hours long. Under real-time fluoroscopic and angiographic guidance, interventional neuroradiologist Monica Pearl, M.D., threaded a micro-catheter up from the baby’s femoral artery through the complex network of blood vessels all the way to her brain. There, in targeted branches of her cerebral arteries, Dr. Pearl strategically placed liquid embolic agent to obstruct blood flow to the abnormal half of Bella’s brain.

Immediately after the first procedure, the team had to contend with the same consequences that come after any stroke: brain swelling that can cause bleeding and herniation, complicated further by the already enlarged hemisphere of Bella’s brain. Using neuroprotective strategies learned from treating hundreds of brain-injured newborns, the neonatal neurocritical care team and the neonatal intensive care unit (NICU) minimized the brain swelling and protected the normal half of the brain by tightly controlling the brain temperature, her sugar and electrolyte levels, her blood pressure and coagulation system.

As the brain tissue in the oversized hemisphere died, so did the seizures that had plagued Bella since birth. She has not had a seizure since she left Children’s National more than one year ago. Her adoptive parents report that Bella is hitting many of the typical developmental milestones for her age: She’s getting ready to walk, blowing kisses and saying a few words. Physical, speech and occupational therapy will keep her moving in the right direction, Dr. Chang says.

“We believe that Children’s National is the only place in the world that’s treating newborns in this way to preserve their futures,” Dr. Chang says. “We’re privileged to be able to care for Bella and other kids with this rare condition.”

Bella’s transfer and successful procedures required the support and collective efforts of many within the hospital organization including William D. Gaillard, M.D., and his surgical epilepsy team; interventional neuroradiology with Dr. Monica Pearl; Neurosurgery; Neonatology and the NICU; social work; and even approval from Robin Steinhorn, M.D., senior vice president of the Center for Hospital-Based Specialties, and David Wessel, M.D., executive vice president and Chief Medical Officer.

“While obvious credit goes to the medical team who saved Bella’s future and the neonatal intensive care nurses who provided exceptional, intensive, one-on-one care, Bella’s team of supporters extend to all levels within our hospital,” Dr. Chang adds.

Coming together as a team for the good of the baby

March 12, 2019

Children’s National has a new program to care for children who have severe bronchopulmonary dysplasia, a serious complication of preterm birth.

Around the 1-year-old’s crib is a tight circle of smiling adults, and at the foot of his bed is a menagerie of plush animals, each a different color and texture and shape to spark his curiosity and sharpen his intellect.

Gone are the days a newborn with extremely complex medical needs like Elijah would transfer from the neonatal intensive care unit (NICU) to the pediatric intensive care unit and transition through a couple of other hospital units by the time he was discharged. Gone are the days when he’d see a variety of new physician faces at every stop. And gone are the days he’d be confined to his room, divorced from the sights and sounds and scents of the outside world, stimulation that helps little baby’s neural networks grow stronger.

Children’s National has a new program designed to meet the unique needs of children like Elijah who have severe bronchopulmonary dysplasia (BPD), a common complication of preterm birth.

“It’s more forward-thinking – and I mean thinking for the future of each individual baby, and it’s allowing the baby to have one team and one location to take advantage of a deep knowledge of and relationship with that baby and family,” says Robin Steinhorn, M.D. Dr. Steinhorn is senior vice president of the Center for Hospital-Based Specialties and one of Children’s multidisciplinary team members who visited Elijah’s bed twice weekly during his lengthy hospitalization and who continues to see him regularly during outpatient visits.

“The pulmonologist, the neonatologist, the respiratory therapist, the physical therapist, the dietitian, the cardiologist – we all come as a team to work together for the good of the baby,” Dr. Steinhorn adds. “We stick with these babies through thick and thin. We will stick with that baby with this team and this location until they are ready to go home – and beyond.”

BPD, a serious lung condition, mostly affects extremely low birthweight preterm babies whose lungs were designed to continue developing inside the womb until the pregnancy reaches full term. Often born months before their due dates, these extremely vulnerable newborns have immature organs, including the lungs, which are not ready for the task of breathing air. Children’s program targets infants who experience respiratory failure from BPD. The respiratory support required for these infants ranges from oxygen delivered through a nasal cannula to mechanical ventilators.

“It’s more forward-thinking – and I mean thinking for the future of each individual baby, and it’s allowing the baby to have one team and one location to take advantage of a deep knowledge of and relationship with that baby and family,” says Robin Steinhorn, M.D.

About 1 percent of all preterm births are extremely low birthweight, or less than 1,500 grams. Within that group, up to 40 percent will develop BPD. While they represent a small percentage of overall births, these very sick babies need comprehensive, focused care for the first few years of their lives. And some infants with severe BPD also have pulmonary hypertension which, at Children’s National, is co-managed by cardiology and pulmonary specialists.

Children’s BPD team not only focuses on the child’s survival and medical care, they focus on the neurodevelopmental and social care that a baby needs to thrive. From enhanced nutrition to occupational and physical therapy to a regular sleep cycle, the goal is to help these babies achieve their full potential.

“These babies are at tremendous risk for long-term developmental issues. Everything we do is geared to alleviate that,” adds John T. Berger III, M.D., director of Children’s Pulmonary Hypertension Program.

“Our NICU care is more focused, comprehensive and consistent,” agrees Mariam Said, M.D., a neonatologist on the team. “We’re also optimizing the timing of care and diagnostic testing that will directly impact health outcomes.”

Leaving no detail overlooked, the team also ensures that infants have age-appropriate developmental stimuli, like toys, and push for early mobility by getting children up and out of bed and into a chair or riding in a wagon.

“The standard approach is to keep the baby in a room with limited physical or occupational therapy and a lack of appropriate stimulation,” says Geovanny Perez, M.D., a pulmonologist on the team. “A normal baby interacts with their environment inside the home and outside the home. We aim to mimic that within the hospital environment.”

Dr. Steinhorn, who had long dreamed of creating this comprehensive team care approach adds that “it’s been so gratifying to see it adopted and embraced so quickly by Children’s NICU caregivers.”

Children’s National senior vice president elected to American Pediatric Society leadership
