CellBuilder: A ready-made solution for cell & gene therapy manufacturing

September 11, 2024

With CellBuilder and our global partnerships, Children’s National hopes to expand access to groundbreaking cell and gene therapy treatments as they take off in the next five years.

With cell and gene therapies poised to reshape cancer and rare disease treatments, researchers at Children’s National Hospital are pioneering ready-to-use solutions that will bring these cutting-edge therapies directly to hospitals and other treatment centers, shrinking the distance between doctors and patients.

“The next five years are going to be a period of tremendous growth for cell and gene therapy,” said Patrick Hanley, Ph.D., chief and director of the Cellular Therapy Program at Children’s National. “Currently, there’s no shortage of interest from the medical community, but there’s a shortage of people who can manufacture and administer this care. We’re looking for ways to get these treatments to the patients by providing other institutions the tools they need to launch these programs cost-effectively, safely and efficiently.”

Called CellBuilder, the starter kits for cell and gene therapy programs could transform the landscape for pediatric patients.

The big picture

Dr. Hanley and many members of the Children’s National team have been working in cell and gene therapy for more than a decade, gaining extensive experience in the technical and regulatory hurdles inherent in creating treatments that target diseases at their source.

In cell therapy, a specific cell type is modified and transferred to a patient with a payload that can target a disease or disorder. For example, T cells may be modified and delivered to patients to teach their immune systems to fight cancer. In gene therapy, a patient’s genetic code is modified to treat or prevent diseases, such as sickle cell disease, cancers and other genetic disorders. This can be done by introducing a healthy copy of a gene, repairing a faulty gene or altering a gene’s function.

Children’s National has become a leader in manufacturing virus-specific T cells, one method of delivering cell therapies, and the Cellular Therapy Program has conducted consortium-led, multi-center trials. Many other healthcare sites across the country want to start programs offering this care at their facilities.

The holdup in the field

Starting a cell and gene therapy program from scratch can take years of effort, training and money. That’s why Jay Tanna, M.S., R.A.C., quality assurance manager of the Cellular Therapy Program at Children’s National, said the team is creating CellBuilder starter kits, which include the manufacturing protocol and the resources necessary to launch a cell therapy program almost instantly.

“With a suitable knowledge base, institutions can start their own cellular therapy program at the point of care, using our manufacturing protocols, vetted reagents and other key elements of the process,” Tanna said. “Of course, interested institutions would have to meet regulatory requirements and establish a clean room to manufacture these therapies. If they want to use CellBuilder to run a clinical trial, they can do that. If they want to take it to become a licensed product, they can do that, too.”

Children’s National has worked with more than five institutions to build their virus-specific T-cell program and is now using the kits to accelerate and commercialize the process to increase patient access. The lab has also entered into a memorandum of understanding with the Tokyo-based Hitachi Global Life Solutions, Inc., an innovative modular clean room manufacturer, with the goal of offering a bundled solution.

Why we’re excited

Dr. Hanley and his colleagues say that the partnerships Children’s National is forging as they consult with other experts in this field will expand access to cell and gene therapy across the country—and hopefully around the world.

“It used to be that, to get a CAR T cell, you would collect the cells at Children’s National, ship them to a company like Novartis, have the therapy manufactured there and then shipped back,” said Michael Keller, M.D., who co-led a first-of-its kind immunotherapy trial as the Translational Research Laboratory director at the Children’s National Cell Enhancement and Technologies for Immunotherapy Program. “It was expensive, time-consuming and limited patient access. Now, there’s growing interest in manufacturing at each site, just like you would with a bone marrow transplant.”

With CellBuilder and our global partnerships, Children’s National hopes to expand access to groundbreaking cell and gene therapy treatments as they take off in the next five years, extending lifetimes and improving the quality of life for children suffering from rare disorders.

“We’re trying to capture the momentum underway in the field by providing this kit so that institutions don’t have to know how to do everything,” Dr. Hanley said. “We provide all the knowledge, a reagent list and everything else they need—and they provide the care.”

Expanding team innovates to take on pediatric brain tumors

Experience, talent and technology are coming together at the Children’s National Research & Innovation Campus to solve the complex challenges of treating pediatric brain tumors through a growing partnership between Children’s National Hospital and Virginia Tech.

Cheng-Chia “Fred” Wu, M.D., Ph.D., joins the team at the campus as an assistant professor at Virginia Tech’s Fralin Biomedical Research Institute. He hopes to improve treatment for pediatric brain tumors and other cancers by leveraging technological advances in focused ultrasound and studying how this modality can be combined with other novel therapies. Children’s National physicians and scientists are collaborating with Virginia Tech scientists to develop these new approaches.

Why we’re excited

Catherine Bollard, M.D., M.B.Ch.B., director of the Center for Cancer and Immunology Research and interim chief academic officer at Children’s National, said collaborations — including the partnership between Children’s National and Virginia Tech — are essential to solving formidable scientific challenges.

“We are thrilled to be working with Dr. Wu to develop cutting-edge therapeutics for pediatric brain tumors,” Dr. Bollard said. “With Dr. Wu’s experience and the talents of our team at Children’s National, I have great hope that we will be able to combine our novel technologies and therapies to provide tremendous breakthroughs for treating pediatric patients with brain tumors.”

Before joining Virginia Tech, Dr. Wu was an assistant professor of radiation oncology at Columbia University Irving Medical Center in New York, where he treated pediatric cancers and central nervous system malignancies.

“Partnering with Children’s National connects us to a world-class clinical trial institute that has been a pioneer in treating brain tumors with focused ultrasound technology, and this presents a unique opportunity to help children and families struggling with cancer,” Dr. Wu said. “I can’t wait to see where this takes us.”

Dr. Wu played a key role in the Initiative for Drug Delivery Innovation for Childhood Brain Tumors at Columbia, developing a bench-to-bedside platform to facilitate the translation of promising technologies for targeted drug delivery in children with brain tumors.

Within three years, the team demonstrated the safety and feasibility of using focused ultrasound in the brainstem and adding radiation in preclinical models. They then opened two clinical trials for kids with relapsed diffuse midline glioma, an aggressive and difficult-to-treat brain tumor that occurs in the brain stem, thalamus and spinal cord.

What’s ahead

Dr. Wu will be involved in a wide range of research touching both organizations, including veterinary medicine and biomedical engineering at Virginia Tech.

Michael Friedlander, Ph.D., executive director of the Fralin Biomedical Research Institute at Virginia Tech Carilion and vice president for health sciences and technology at Virginia Tech, welcomed Dr. Wu’s experience as a pediatric radiation oncologist, translational physician-scientist and clinical trialist who has led an innovative drug delivery program.

“He is armed with a unique set of skills to identify promising new technology and implement it in areas of great need for treatment of pediatric cancers,” Dr. Friedlander said. “We are absolutely delighted to have Dr. Wu as part of the team. He represents a powerful new part of the strong partnership between Virginia Tech and Children’s National Hospital for addressing pediatric brain cancer.”

Around the world

July 2, 2024

Our Global Health Initiative launched in 2016 with the goal of eliminating pediatric health disparities around the world. We aim to address the most pressing pediatric health issues through better care for medically underserved populations. This leadership helps us achieve our mission of caring for all children. A broad range of education and research projects improves health outcomes. They also offer enriching opportunities for experienced faculty and emerging leaders to advance clinical excellence.

Healing hearts in Uganda

Dr. Craig Sable and team train partners in Uganda.

Craig Sable, M.D., interim chief of Cardiology, improves care for young people with rheumatic heart disease (RHD) in Uganda. Donors, including the Karp Family Foundation, Huron Philanthropies, Zachary Blumenfeld Fund and the Wood family, make this possible. RHD affects 50 million people, mostly children, worldwide. It claims 400,000 lives each year.

Dr. Sable and Ugandan partners completed important research showing that early RHD detection, coupled with monthly penicillin treatment, can protect the heart. They are working on practical solutions, such as a new portable device with artificial intelligence (AI) that can easily screen for RHD.

In 2023, Dr. Sable led two missions in Uganda where he and his team did surgeries and special tests for 18 children with RHD. They also taught local doctors new skills to help more kids on their own.

Plastic surgery and reconstructive care in Kenya and Nepal

Each year our Craniofacial & Pediatric Plastic Surgery team, under the leadership of Johnston Family Professor of Pediatric Plastic Surgery and Chief of Pediatric Plastic Surgery Gary Rogers, M.D., J.D., LL.M., M.B.A., M.P.H., provides opportunities for fellows to participate in surgical missions.

In 2024, Perry Bradford, M.D., traveled to the Moi Teaching Hospital in Eldoret, Kenya where she provided patients with burn, pressure wound and cleft reconstruction. She built community connections with the local plastic surgeons and educated registrars and medical students. “This gave me firsthand experience working in a community with limited resources and forced me to be more creative,” Dr. Bradford says. “The experience inspired me to examine what it means to have consistent access to advanced tools and equipment.”

In 2022, a group traveled to Nepal to provide care. Some patients arrived after days of travel by yak or buffalo. One child with a burn injury recovered use of her hand. The team educated local providers to deliver life-changing treatments unavailable in Nepal.

Elevating epilepsy care in Ethiopia

Neurologist Tesfaye Zelleke, M.D., and partners in Ethiopia are seeking to improve the lives of children with epilepsy. The BAND Foundation provides support. Ethiopia has a population of about 120 million yet only a handful of pediatric neurologists.

Dr. Zelleke’s team trained nonspecialist providers to diagnose and treat children in the primary care setting. They also launched a mobile epilepsy clinic to provide community care and build the capacity of local clinicians. In collaboration with advocacy groups, the team educates the public about epilepsy with a goal of reducing stigma.

New hope in Norway

In 2023, our Division of Colorectal & Pelvic Reconstruction shared its expertise with clinicians at Oslo University Hospital, Rikshospitalet, in Norway. This effort was a key first step in Oslo becoming the first dedicated colorectal center in Scandinavia.

Marc Levitt, M.D., and team members performed complex surgeries otherwise unavailable for waiting patients. They led an academic conference. They held clinics to educate nurses, reviewed patient records and made care recommendations. Specialized care enabled a young patient with significant bowel difficulties to recover function and lead a normal life.

The team will travel to South Africa, the Czech Republic and Spain in 2024. Donors, including The Dune Road Foundation and Deanna and Howard Bayless, make this work possible.

Improving outcomes for babies in the Congo

AI can be a valuable tool for diagnosing genetic conditions. It detects unique facial patterns that clinicians without genetics training can miss. However, existing facial analysis software struggles in nonwhite populations.

A team led by Marius George Linguraru, D.Phil., M.A., M.Sc., the Connor Family Professor of Research and Innovation and principal investigator in the Sheikh Zayed Institute for Pediatric Surgical Innovation, is working to improve the newborn diagnosis rate worldwide. They are testing smartphone software in the Democratic Republic of Congo. Diverse newborn data improves AI’s ability to detect a variety of genetic conditions in more children. Early detection, diagnosis and informed care lead to better health outcomes.

Marva Moxey-Mims, M.D.,, chief of Nephrology, is bringing care to children with kidney disease in Jamaica, with a goal of improving health equity. An International Pediatric Nephrology Association grant helped make it possible.

On a recent trip, Dr. Moxey-Mims and a small team — including Jennifer Carver, RN, CNN, lead peritoneal dialysis nurse at Children’s National, and three pediatric nephrologists from Jamaica — trained nearly 30 nurses from Jamaican hospitals. Nurses received hands-on dialysis education to improve their clinical skills. The team also worked to educate the community in disease awareness and prevention.

Pandemic stress in pregnant mothers may affect anxiety regions of babies’ brains

June 20, 2024

The research from Children’s National Hospital provides mounting evidence that children of the pandemic, even those far too young to understand it, need ongoing assessments of developmental or mental health support later in life.

A critical part of the brain linked to risks for anxiety later in life – the left amygdala – was significantly smaller by volume in babies of mothers who reported stress during the COVID-19 pandemic, according to a new manuscript published in JAMA Network Open.

The right hippocampus, which governs spatial, visual and verbal memories, and the white matter were also reduced in children whose mothers reported stress.

The research from Children’s National Hospital provides mounting evidence that children of the pandemic, even those far too young to understand it, need ongoing assessments of developmental or mental health support later in life.

“Looking ahead, we want to use this information – and studies with similar findings – to empower pregnant mothers to request support to mitigate their stress, especially in the event of another global health crisis,” said Nickie Andescavage, M.D., a neonatologist and principal investigator at the Center for Prenatal, Neonatal & Maternal Health Research. “We also want to make sure babies born during COVID-19 get the services that they need in life if they develop anxiety or other mental health disorders.”

The fine print

Researchers at the center used magnetic resonance imaging (MRI) to compare the brains of 103 babies born between 2014 and 2019 prior to the pandemic to 59 born between 2020 and 2022. Mothers who had COVID-19 or other complications in their pregnancies were excluded. The babies underwent MRI imaging while in utero and again soon after delivery.

The mothers were evaluated for stress and anxiety, using the Spielberger State-Train Anxiety Inventory and other evidence-based scoring measures. Pre-pandemic, 21% of mothers reported elevated symptoms of anxiety; in the pandemic cohort, that number jumped to nearly 62%.

Their babies’ brains were also changed, as regions widely understood to control emotion and anxiety displayed smaller volumes on MRI imaging. Given the global impact of the pandemic and universal reports of mental distress worldwide, the potential impact of these findings may impact an entire generation of children born during the pandemic. The team is just beginning to unravel the medical significance.

What’s next

Catherine Limperopoulos, Ph.D., director of the Center for Prenatal, Neonatal & Maternal Health Research, said understanding the impact of stress is vital in supporting the healthy development of young children. Current studies are underway at her center to tease apart the role of stress in prenatal development and examine its long-term impact on development, including cognition, behavior and mental health.

“We all know that being pregnant can be quite stressful, and there are certain times of collective stress that can provide us windows to understand how the body and mind manage it,” Dr. Limperopoulos said. “At our center, we care deeply about the health of mothers and babies, and our researchers plan to continue investigating the role of stress in development to continue building data to show that mental health must be a greater priority.”

This study – “Prenatal maternal psychological distress during the COVID-19 pandemic and newborn brain development” – was supported by the National Institutes of Health, the Intellectual and Developmental Disabilities Research Center, and the A. James & Alice B. Clark Foundation. You can read the full study in JAMA Network Open.

Tailored care for children with autism improves EEG experience

May 23, 2024

Most children with a developmental disability can complete EEG with sufficient support.

Electroencephalographic (EEG) monitoring is an important tool for diagnosing seizures, epilepsy and other neurologic conditions. However, many children with developmental disabilities – including autism – have difficulty undergoing hospital tests like EEG. Furthermore, sometimes these tests are not prescribed or turn out to be unsuccessful.

In a new study published in Journal of Child Neurology, findings from a Children’s National Hospital team indicate that most children with a developmental disability can complete EEG with sufficient support. Special planning can identify children who would benefit from accommodations to help them complete the study successfully.

What this means

Children with developmental disabilities have an increased risk of epilepsy and need for overnight video EEG monitoring. However, video EEGs have historically been considered difficult to complete for this population. Experts at Children’s National implemented a coordinated team approach to help children with developmental disability tolerate overnight video EEGs. The project involved a caregiver preprocedure questionnaire shared with the team to create personalized care plans.

These findings suggested that most children with developmental disability can complete video EEG with sufficient support. Preprocedure planning can identify children who would benefit from additional accommodations.

Moving the field forward

The findings show new knowledge through vigorous research about the patient experience and the value of a team dedicated to helping children with development disabilities undergo hospital tests.

“We were excited to find that with special planning more children with developmental disabilities could complete an EEG,” said Elizabeth Wells, M.D., senior vice president at the Center for Neuroscience and Behavioral Medicine at Children’s National, and one of the study’s authors. “We thought it was important to study and discover that children from minority or underrepresented groups were less likely to access support services, which means more work and research is necessary to ensure that services are accessible to these children.”

The authors also found that parent-reported difficulties with communication and cooperation were associated with video EEG success, which means doctors and hospital teams should always ask about and listen to parent input in planning the tests for children.

How Children’s National is leading the way

Healthcare workers often express lack of confidence in their ability to provide care for patients with autism and associated disabilities and express an interest in gaining access to resources and training to better care.

By developing a program to improve care and then studying it through rigorous research, the authors aspire to spread a message of hope. Programs like these can ensure all kids get the tests and care they need. Children’s National is also a leader in showing the importance of parent input in medical care planning, which too often is not a routine part of care at hospitals.

Further research is necessary to clarify which supports are most helpful.

Adjusting key protein could improve brain function in children with fetal alcohol syndrome

May 16, 2024

Researchers at Children’s National are testing whether controlling the level of apolipoprotein E could serve as an effective treatment for the poor neurobehavioral outcomes tied to fetal alcohol spectrum disorders.

Reduced levels of a protein – called apolipoprotein E – are responsible for the lifelong cognitive and neurological symptoms in fetal alcohol spectrum disorders (FASD), according to a new study published in the journal Molecular Psychiatry. For the first time, researchers at Children’s National Hospital are testing whether controlling the level of this protein could serve as an effective treatment for the poor neurobehavioral outcomes tied to FASD, which is believed to affect roughly 5% of school-aged children.

Apolipoprotein E is controlled by a gene called APOE, a well-known risk gene for Alzheimer’s disease. It contains the instructions that guide how the connections between neurons in the brain strengthen or weaken over time. This process, known as synaptic plasticity, is crucial for learning and memory formation. In this study, plasma was collected from participants at two sites in Western Ukraine, along with information about drinking behavior reported by their mothers.

What this means

“In addition to Alzheimer’s risk, we found this gene is also a crucial contributor to cognitive problems in children with FASD,” said Kazue Hashimoto-Torii, Ph.D., a principal investigator at the Center for Neuroscience Research at Children’s National. “The new data shows that we understand the mechanism by which prenatal alcohol exposure causes a decrease of the APOE level in the brain. We will continue this work to help improve our understanding of FASD, hoping to replenish this important protein and improve outcomes for children with these disorders.”

FASD is an umbrella diagnosis for the physical and developmental challenges that face children who are exposed to alcohol in utero, including intellectual disability, delay in motor and language development and other neurological diagnoses. While alcohol alone is problematic to many aspects of development, evidence also suggests that genetic factors play a role. Only 4.3% of children with heavy alcohol exposure develop FASD, and twin studies have revealed that fraternal twins have different FASD outcomes compared to identical twins.

What’s next

The research team at Children’s National wanted to pinpoint places where genes could play a role and consider therapies. For the first time, researchers found that plasma levels of APOE were reduced in children with FASD, which strongly supports a potential target for therapy. In addition, their genomics study found a variant of APOE increases the risk of cognitive problems in subjects who were prenatally exposed to alcohol, especially those of African ancestry.

“We found that providing a drug that activates the APOE receptor rescued learning deficits and anxiety in pre-clinical models,” said Masaaki Torii, Ph.D., principal investigator at the Center for Neuroscience Research. “The implications offer an exciting glimpse into possible therapies for some of the neurological harms associated with prenatal alcohol exposure and FASD.”

Addressing long-term brain effects of congenital heart disease

May 13, 2024

Dr. Anitha John, medical director of the Washington Adult Congenital Heart Program at Children’s National Hospital, presenting on the lifelong effects of congenital heart disease on brain health at a recent symposium.

About 81% of the 40,000 babies born in the United States with congenital heart disease (CHD) are expected to survive to at least age 35, according to the Centers for Disease Control and Prevention. As survival rates have increased in recent decades, clinicians treating CHD patients are seeking to improve outcomes by understanding the long-term health effects and complications that arise for them.

Anitha John, M.D., Ph.D., medical director of the Washington Adult Congenital Heart Program at Children’s National Hospital, presented an overview of what researchers currently know about the lifelong effects of CHD on brain health at a symposium focused on the heart-brain continuum presented by Children’s National Innovation Ventures, CobiCure and JLABS @ Washington, D.C. She also discussed critically needed advancements in monitoring technology to help clinicians better understand and address how CHD affects the brain.

Why it matters

Based on data collected from adults and children with the condition, Dr. John shared that people with CHD face many potential lifelong challenges and risks, which vary based on disease severity:

About one-third report a mood disorder, either anxiety or depression
25% higher risk of substandard academic outcomes
50% more likely to require special education services
Higher incidence of motor skills impairment
Higher lifetime prevalence of ADHD
Generally lower educational attainment at adulthood
Higher risk of autism spectrum disorders
Higher rate of dementia before the age of 65

Why do some people with CHD experience profound, lifelong brain effects? Dr. John notes that clinicians and researchers are seeking those answers, recognizing that they likely involve various factors and accumulating issues that occur over the entire lifespan, from fetal life onward.

Because the heart supplies the brain with oxygen through circulated blood, the diagnostic tool clinicians most want for patients of all ages is a technology that enables noninvasive monitoring of central venous pressure, an indicator of the volume of blood returning to the heart and the pressure within the heart. Currently, the most reliable way to measure this pressure is by an invasive procedure in which a catheter is inserted into the patient’s subclavian or internal jugular vein or by placing a device into the patient’s pulmonary artery. These procedures have limitations and cannot be used for routine surveillance.

What’s next

Dr. John says noninvasive central venous pressure monitoring is important to understanding and addressing what is causing brain injury in CHD patients. She says the challenges in developing this monitoring solution include the need for an individualized approach, a design that accommodates multidisciplinary use, sizing for patients from infants to adulthood, usability for all age groups and avoiding stigma for wearers.

To address this need, the Alliance for Pediatric Device Development – a consortium funded by the Food and Drug Administration and led by Children’s National – is partnering with CobiCure to issue a request for proposals for direct device funding. The goal is to provide funding to innovators who offer solutions to the dire unmet need for pediatric devices that provide noninvasive monitoring of the circulatory system and heart performance. Details will be announced in June 2024.

Pilot program improves well-being of families during advanced care planning

May 3, 2024

Children with life-limiting rare diseases and their caregivers face tremendous stress and anxiety about the heart-breaking decisions before them. A new intervention – designed at Children’s National Hospital to support the palliative needs of these families – improved their spiritual and emotional well-being, according to new research published in the journal, Pediatrics.

Called FACE Rare (FAmily CEntered Pediatric Advance Care Planning Intervention for Rare Diseases), the counseling tools were found to be safe, effective and increased feelings of peace among families in this underserved population.

“Seventy-four percent of the families in that intervention group reported feelings of sadness, yet 100% reported our pilot intervention was a worthwhile experience,” said Maureen Lyon, Ph.D., a clinical psychologist and principal investigator at the Center for Translational Research at Children’s National. “If you’re talking about the possibility that the worst thing in the world would happen to you – that your child might die, and what you would want for them – the families found that our intervention helped. They had a place to process their feelings and consider what would be important to their child.”

The big picture

A rare disease is defined as any condition affecting fewer than 200,000 people in the United States. In pediatrics, these diseases often require constant caregiving and require families to face the cruel reality that the diagnosis may be life-limiting. In such cases, clinical teams often decide that conversations about advanced care planning (ACP) are needed.

The pilot-phase, randomized trial enrolled patients from Children’s National between 2021 and 2023. Research nurses underwent two days of training to be certified in the new intervention. Families assigned to the new approach received three, weekly 60-minute sessions and were evaluated using evidence-based assessment tools, including the Carer Support Needs Assessment Tool/Action Plan and the Next Steps: Respecting Choices Pediatric ACP Conversation. Measures of anxiety and spiritualization were tracked, and families returned after three months for follow-up.

Patients had a range of diagnoses that put tremendous strain on the caregivers, including complex digestive disorders, white-matter diseases and rare forms of epilepsy. Yet the caregivers expressed similar challenges: having time for themselves during the day, knowing what to expect in the future for their child’s care, and managing financial, legal and work issues.

What we found

Reinforcing the need to improve engagement and support for these families, the investigative team found that those who received the FACE Rare intervention reported higher levels of spiritual meaning and peace than those who received “treatment as usual.” All families living below the poverty line reported greater anxiety, and noteworthy to the team, black caregivers were less likely to report caregiver distress than non-black caregivers.

Dr. Lyon said future research needs to understand better how families respond to the challenges of rare diseases and unique social determinants of health that can change the approach to care.

“In some cultures, and families, having strong feelings is discouraged,” Dr. Lyon said. “We want to give families and caregivers space to have these emotions and think about what would be important for their child, if the worst were to happen. They appreciated that they participated in the program and had the space to consider these difficult questions.”

Artificial – and accelerated – intelligence: endless applications to expand health equity

April 24, 2024

In the complex world of pediatric diseases, researchers need access to data to develop clinical trials and the participation of vulnerable patients to develop new devices and therapies. Both are in short supply, given that most children are born healthy, and most severe pediatric diseases are rare.

That creates a dilemma: how do researchers build a foundation to advance new treatments? Enter artificial intelligence (AI).

“AI is the equalizer: accelerated intelligence for sick kids. No other advance on the horizon holds more promise for improving equity and access to pediatric healthcare when diseases are rare and resources are limited,” says Marius George Linguraru, D.Phil., M.A., M.Sc., the Connor Family Professor in Research and Innovation and principal investigator in the Sheikh Zayed Institute for Pediatric Surgical Innovation (SZI). “AI will shrink the distance between patient and provider, allowing our physicians and scientists to provide targeted healthcare for children more efficiently. The possibilities are endless.”

Why we’re excited

By pioneering AI innovation programs at Children’s National Hospital, Dr. Linguraru and the AI experts he leads are ensuring patients and families benefit from a coming wave of technological advances. The team is teaching AI to interpret complex data that could otherwise overwhelm clinicians. Their work will create systems to identify at-risk patients, forecast disease and treatment patterns, and support complex clinical decisions to optimize patient care and hospital resources. Already, the AI team at SZI has developed data-driven tools touching nearly every corner of the hospital:

AI for rheumatic heart disease (RHD): In partnership with Children’s National cardiology leaders, including Craig Sable, M.D., the Uganda Heart Institute and Cincinnati Children’s Hospital, the AI team has developed an algorithm that can use low-cost, portable ultrasound imaging to detect RHD in children and young adults, a disease that takes nearly 400,000 lives annually in limited-resource countries. Early testing shows the AI platform has the same accuracy as a cardiologist in detecting RHD, paving the way for earlier treatment with life-saving antibiotics. This year, Children’s National physicians will be in Uganda, screening 200,000 children with local cardiology experts and AI technology.
Newborn screening for genetic conditions with mGene: Working with Rare Disease Institute clinicians and Chief of Genetics and Metabolism Debra Regier, M.D., the AI team has built technology to detect rare genetic disorders, using an algorithm and a smartphone camera to identify subtle changes in facial features. Tested on patients from over 30 countries and published in The Lancet Digital Health, the application helps screen children for advanced care when a geneticist may not be within reach. With funding from the National Institutes of Health, Children’s National and its research partners are piloting a newborn screening program in the Democratic Republic of the Congo.
Pediatric brain tumors: To improve and personalize the treatment decisions for children with brain tumors, Dr. Linguraru’s team is working with Brain Tumor Institute Director Roger Packer, M.D., the Gilbert Family Distinguished Professor of Neurofibromatosis, on algorithms that can characterize and measure brain tumors with unprecedented precision. The team recently won the International Pediatric Brain Tumor Segmentation Challenge, distinguishing the Children’s National algorithm as among the best in the world.
Ultra-low field magnetic resonance imaging (MRI): With a grant from the Bill & Melinda Gates Foundation, the AI team is working alongside Children’s Hospital Los Angeles, King’s College London and the UNITY Consortium to expand global brain imaging capacity. The consortium is helping clinicians in limited-resource countries improve the treatment of neonatal neurological conditions, using AI to boost the quality of ultra-low field MRI and expand access to this portable and more affordable imaging option.
Federated learning: Children’s National has collaborated with NVIDIA and other industry leaders to accelerate AI advances through federated learning. Under this approach, institutions share AI models rather than data, allowing them to collaborate without exposing patient information or being constrained by essential data-sharing restrictions. The SZI team was the only pediatric partner invited to join the largest federated learning project of its kind, studying the lungs of COVID-19 patients. Details were published in Nature Medicine.

Children’s National leads the way

Looking ahead, the Children’s National AI team is pursuing a wide range of advances in clinical care. To support patients treated at multiple clinics, they are developing systems to harmonize images from different scanners and protocols, such as MRI machines made by different manufacturers. Similar work is underway to analyze pathology samples from different institutions consistently.

Automation is also making care more efficient. For example, using data from 1 million chest X-rays, the team is collaborating with NVIDIA to develop a conversational digital assistant that will allow physicians to think through 14 possible diagnoses.

Dr. Linguraru says he and his colleagues are galvanized by the jarring statistic that one in three children with a rare disease dies before age 5. While well-implemented AI initiatives can change outcomes, he says the work must be done thoughtfully.

“In the future, patients will be evaluated by human clinicians and machines with extraordinary powers to diagnose illness and determine treatments,” Dr. Linguraru said. “Our team at Children’s National is leading conversations about the future of pediatric healthcare with a focus on safety, resource allocation and basic equity.”

Learn more about our AI initiatives

Innovation leaders at Children’s National Hospital are building a community of AI caregivers through educational and community-building events. At the inaugural Symposium on Artificial Intelligence in 2023 at the Children’s National Research & Innovation Campus, experts from Virginia Tech, JLABS, Food and Drug Administration, Pfizer, Oracle Health, NVIDIA, AWS Health and elsewhere laid out a vision for using data to advance pediatric medicine. The symposium will return on Sept. 6.

Dr. Linguraru is the program chair of MICCAI 2024, the top international meeting on medical image computing and computer-assisted intervention and the preeminent forum for disseminating AI developments in healthcare. The conference is an educational platform for scientists and clinicians dedicated to AI in medical imaging, with a focus on global health equity. It will take place for the first time in Africa on Oct. 6-10.

Pioneering research center aims to revolutionize prenatal and neonatal health

February 29, 2024

1 2 3 4

Catherine Limperopoulos, Ph.D., was drawn to understanding the developing brain, examining how early adverse environments for a mother can impact the baby at birth and extend throughout its entire lifetime. She has widened her lens – and expanded her team – to create the new Center for Prenatal, Neonatal & Maternal Health Research at Children’s National Hospital.

“Despite the obvious connection between mothers and babies, we know that conventional medicine often addresses the two beings separately. We want to change that,” said Dr. Limperopoulos, who also directs the Developing Brain Institute. “Given the current trajectory of medicine toward precision care and advanced imaging, we thought this was the right moment to channel our talent and resources into understanding this delicate and highly dynamic relationship.”

Moving the field forward

Since its establishment in July 2023, the new research center has gained recognition through high-impact scientific publications, featuring noteworthy studies exploring the early phases of human development.

Dr. Limperopoulos has been at the forefront of groundbreaking research, directing attention to the consequences of maternal stress on the unborn baby and the placenta. In addition, under the guidance of Kevin Cook, Ph.D., investigators published a pivotal study on the correlation between pain experienced by premature infants in the Neonatal Intensive Care Unit and the associated risks of autism and developmental delays.

Another area of research has focused on understanding the impact of congenital heart disease (CHD) on prenatal brain development, given the altered blood flow to the brain caused by these conditions during this period of rapid development. Led by Josepheen De Asis-Cruz, M.D., Ph.D., a research team uncovered variations in the functional connectivity of the brains of infants with CHD. In parallel, Nickie Andescavage, M.D., and her team employed advanced imaging techniques to identify potential biomarkers in infants with CHD, holding promise for guiding improved diagnostics and postnatal care. Separately, she is investigating the impact of COVID-19 on fetal brain development.

In the months ahead, the team plans to concentrate its efforts on these areas and several others, including the impact of infectious disease, social determinants of health and protecting developing brains from the negative impacts of maternal stress, pre-eclampsia and other conditions prevalent among expectant mothers.

Assembling a team

Given its robust research plan and opportunities for collaboration, the center pulled together expertise from across the hospital’s faculty and has attracted new talent from across the country, including several prominent faculty members:

Katherine L. Wisner, M.S., M.D., has accumulated extensive knowledge on the impact of maternal stress on babies throughout her career, and her deep background in psychiatry made her a natural addition to the center. While Dr. Wisner conducts research into the urgent need to prioritize maternal mental health, she will also be treating mothers as part of the DC Mother-Baby Wellness Initiative — a novel program based at Children’s National that allows mothers to more seamlessly get care for themselves and participate in mother-infant play groups timed to align with their clinical appointments.
Catherine J. Stoodley, B.S., M.S., D.Phil., brings extensive research into the role of the cerebellum in cognitive development. Dr. Stoodley uses clinical studies, neuroimaging, neuromodulation and behavioral testing to investigate the functional anatomy of the part of the brain responsible for cognition.
Katherine M. Ottolini, M.D., attending neonatologist, is developing NICU THRIVE – a research program studying the effects of tailored nutrition on the developing newborn brain, including the impact of fortifying human milk with protein, fat and carbohydrates. With a grant from the Gerber Foundation, Dr. Ottolini is working to understand how personalized fortification for high-risk babies could help them grow.

Early accolades

The new center brings together award-winning talent. This includes Yao Wu, Ph.D., who recently earned the American Heart Association’s Outstanding Research in Pediatric Cardiology award for her groundbreaking work in CHD, particularly for her research on the role of altered placental function and neurodevelopmental outcomes in toddlers with CHD. Dr. Wu became the third Children’s National faculty member to earn the distinction, joining an honor roll that includes Dr. Limperopoulos and David Wessel, M.D., executive vice president and chief medical officer.

Interim Chief Academic Officer Catherine Bollard, M.D., M.B.Ch.B., said the cross-disciplinary collaboration now underway at the new center has the potential to make a dramatic impact on the field of neonatology and early child development. “This group epitomizes the Team Science approach that we work tirelessly to foster at Children’s National,” Dr. Bollard said. “Given their energetic start, we know these scientists and physicians are poised to tackle some of the toughest questions in maternal-fetal medicine and beyond, which will improve outcomes for our most fragile patients.”

Next-generation genomics testing holds key to undiagnosed rare disease

February 28, 2024

Seth Berger, M.D., Ph.D., felt the pull to dig deeper when he started reading the chart. An 11-year-old boy had an abnormal gait and couldn’t even walk in a straight line down the sidewalk to go trick-or-treating. Yet workups with neurology, orthopedics and an exome analysis of the patient’s genetic code did not provide a diagnosis. He had been getting worse for roughly three years.

With one of the largest clinical genetics departments in the country, Children’s National Hospital receives more than 10,000 visits a year from patients like this middle schooler. Often, they are children and caregivers who are searching for answers and follow-up support for diagnoses of genetic disorders, which impact so few people that only highly trained geneticists and genetic counselors can get to the root of the disorder.

“In genetics, we are finding layers of understanding. A negative clinical test is not always the final answer because the significance of variants can often be missed or misunderstood,” said Dr. Berger, a medical geneticist and principal investigator in the Center for Genetics Medicine Research at Children’s National. “It can take extensive research and a deep knowledge of the limits of certain tests to reach a diagnosis.”

The fine print

On page 4 of the patient’s genetics report, Dr. Berger found a reference to a pair of variants with no known clinical impact. Dr. Berger recognized that the genes referenced could affect proteins that drive potentially treatable neurological outcomes.

Dr. Berger ordered further testing, including biochemical testing of the patient’s blood and a phenylalanine loading challenge, a test that measures how the body metabolizes certain amino acids. With the results, he confirmed a recessive GCH1 deficiency in the patient was causing a condition called DOPA-responsive dystonia, a disorder that causes involuntary muscle contractions, tremors and uncontrolled movements. Laura Schiffman Tochen, M.D., director of the Movement Disorders Program at Children’s National, started the patient on levodopa-carbidopa — a drug combination used to treat Parkinson’s disease and other neurological disorders — and within two hours the boy showed improvement. His gait was almost normal.

Why we’re excited

Dr. Berger presents at conferences on this case and several other medical mysteries that he’s recently solved in his clinical practice and his role at the Pediatric Mendelian Genomics Research Center, a Children’s National program immersed in a federally funded research study to better understand how differences in genetic material can affect human health. As part of his work, he’s joined the GREGoR project (Genomic Research to Elucidate the Genetics of Rare Disease), which hopes to increase the number of genetic disorders where a cause can be identified. The elite genetics consortium includes nationally recognized research centers – the University of California at Irvine, Broad Institute, University of Washington, Baylor University, Stanford University, Invitae and Children’s National – which are working together to harness cutting-edge genomics sequencing capabilities. They hope to enroll thousands in their research, funded by the National Institutes of Health.

“It’s truly stunning what genetic sequencing can find. The outcomes can be life-changing,” said Dr. Berger. “These cases with life-altering diagnoses don’t come along every day, but when they do, they make the hunt to find answers all the more worthwhile.”

School entry neurodevelopmental outcomes of Zika-exposed Colombian children

February 26, 2024

The Children’s National Hospital Zika Research Team and collaborators from Biomelab, in Barranquilla, Colombia take a picture after a study visit in Sabanalarga, Colombia following the neurodevelopmental outcomes of children who had in utero exposure to Zika virus. Pictured from Children’s National Hospital: Dr. Sarah Mulkey, Regan Andringa-Seed, Margarita Arroyave-Wessel, and Dr. Madison Berl.

The long-term neurodevelopmental effects of antenatal Zika virus (ZIKV) exposure in children without congenital Zika syndrome (CZS) remain unclear, as few children have been followed to the age of starting primary school.

In a new study published in Pathogens, researchers found children with in utero ZIKV exposure appear to have an overall positive developmental trajectory at 4 to 5 years of age but may experience risks to neurodevelopment in areas of emotional regulation and adaptive mobility.

The hold up in the field

Children who were born during the ZIKV epidemic and who had in utero exposure to ZIKV are only now at the age to start school. Child neurodevelopmental outcome data has not been reported at the age of school entry for children with antenatal ZIKV exposure who do not have the severe birth defects of CZS.

“As these children approach the early school-age years, we aim to examine whether there are neurodevelopmental differences in executive function, motor ability, language development or scholastic skills as compared to a group of unexposed control participants from the same communities in Colombia,” says Sarah Mulkey, M.D., Ph.D., prenatal-neonatal neurologist in The Zickler Family Prenatal Pediatrics Institute at Children’s National Hospital and lead author of the study.

Moving the field forward

Building on previous findings, this study presents the longitudinal outcomes of a well-characterized Colombian cohort of ZIKV-exposed children without CZS at ages 4 to 5 years. These children have been seen for neurodevelopmental follow-up as infants and toddlers at approximately 6 months, 18 months and 3 years of age as part of an international collaboration between researchers in Barranquilla, Colombia and at Children’s National beginning in 2016. The objective of this study was to assess the multi-domain neurodevelopmental outcomes in 4 to 5-year-old children with antenatal ZIKV exposure without CZS compared to unexposed controls in Colombia.

Why we’re excited

Many of the children who had antenatal ZIKV exposure are making good progress in multiple areas of their neurodevelopment. However, the researchers found that children with antenatal ZIKV exposure have differences in areas of emotional regulation, executive function, mood and behavior which may relate to virus exposure during their early brain development.

“These areas of brain function are important for future academic achievement, employment, mental health and social relationships,” says Dr. Mulkey. “So, it will be important to continue to follow these children at older ages when they start school.”

Children’s National leads the way

Children’s National is a leader in conducting outcome studies of children born following antenatal ZIKV exposure. This study follows children in Colombia who are now 5 years old who were first studied while they were in the womb. These children have contributed unique longitudinal understanding to early child neurodevelopment following in utero exposure to ZIKV.

Dr. Mulkey is committed to studying the long-term neurodevelopmental impacts that viruses like Zika and SARS-CoV-2 have on infants born to mothers who were infected during pregnancy through research with the Congenital Infection Program at Children’s National and in collaboration with colleagues in Colombia.

Additional Children’s National authors include Meagan Williams M.S.P.H., C.C.R.C., senior research coordinator; Regan Andringa-Seed, clinical research coordinator, Margarita Arroyave-Wessel, clinical research coordinator; L. Gilbert Vezina, M.D., director, Neuroradiology Program; Dorothy Bulas, M.D., chief, Diagnostic Imaging and Radiology; Robert Podolsky, biostatistician.

New hemimegalencephaly procedure is all about teamwork

February 23, 2024

Children’s National experts pioneered a novel approach of inducing strokes to stop seizures and improve neurodevelopmental outcomes in newborns under three months old with hemimegalencephaly (HME). The procedure, called an endovascular embolic hemispherectomy, can be safely used to provide definitive treatment of HME-related epilepsy in neonates and young infants. Monica Pearl, M.D., neurointerventional radiologist, and Panagiotis Kratimenos, M.D., Ph.D., neonatologist, discuss why having a multidisciplinary team skilled at this procedure is the reason we’re the only center in the world capable of providing this treatment.

The history behind the novel hemimegalencephaly procedure

February 23, 2024

Traditionally, when a baby is diagnosed with hemimegalencephaly (HME), doctors turn to a hemispherectomy at 3 months of age, which involves surgically removing half of a baby’s brain. At Children’s National Hospital, our doctors pioneered the endovascular embolic hemispherectomy, an approach using induced controlled strokes to eliminate the affected part of the brain, halting seizures. Monica Pearl, M.D., neurointerventional radiologist, and Tammy Tsuchida, M.D., Ph.D., neonatal neurologist, talk about this life-changing procedure.

Inducing strokes to better treat babies with hemimegalencephaly

February 23, 2024

When a family from Texas received a shocking diagnosis for their newborn daughter, they knew there was one place they needed to go – Children’s National Hospital in Washington, D.C. At birth, Angelique was diagnosed with a rare and devastating condition known as hemimegalencephaly (HME) which causes uncontrollable and frequent seizures. Monica Pearl, M.D., neurointerventional radiologist, and the team at Children’s National have pioneered an approach to treat HME, where they induce controlled strokes to eliminate the affected part of the brain, halting seizures in their tracks. They’re the only team in the world doing this work. Angelique’s parents knew the clock was ticking — every day they waited meant irreversible damage to their daughter’s developing brain.

Prenatal COVID exposure associated with changes in newborn brain

February 21, 2024

The team found differences in the brains of both infants whose mothers were infected with COVID while pregnant, as well as those born to mothers who did not test positive for the virus.

Babies born during the COVID-19 pandemic have differences in the size of certain structures in the brain, compared to infants born before the pandemic, according to a new study led by researchers at Children’s National Hospital.

The team found differences in the brains of both infants whose mothers were infected with COVID while pregnant, as well as those born to mothers who did not test positive for the virus, according to the study published in Cerebral Cortex.

The findings suggest that exposure to the coronavirus and being pregnant during the pandemic could play a role in shaping infant brain development, said Nickie Andescavage, M.D., the first author of the paper and associate chief for the Developing Brain Institute at Children’s National.

The fine print

The study’s authors looked at three groups of infants: 108 born before the pandemic; 47 exposed to COVID before birth; and 55 unexposed infants. In all cases, researchers performed magnetic resonance imaging (MRI) scans of the newborns’ brains during the first few weeks of life. The MRI scans, which are non-invasive and do not expose patients to radiation, provided 3D images of the brain, allowing doctors to calculate the volume of different areas.

Researchers found several differences in the brains of babies exposed to COVID. They had larger volumes of the gray matter that makes up the brain’s outermost layer, compared to the two other groups. In contrast, an inner area of the brain, known as deep gray matter, was smaller than in unexposed babies. These are areas that contain large numbers of neurons that generate and process signals throughout the brain. “Their brains formed differently if they were exposed to COVID,” said Dr. Andescavage, adding that “those exposed to COVID had unique signatures” in the brain.

Doctors also measured the depths of the folds in the babies’ brains – a way to determine how the brain is maturing during early development. Babies born to mothers who had COVID in pregnancy had deeper grooves in the frontal lobe, while babies born during the pandemic – even without being exposed to COVID – had increased folds and grooves throughout the brain, compared to babies born before the pandemic. “There was something about being born during the pandemic that changed how the brain developed,” Dr. Andescavage said.

What’s ahead

The study authors can’t fully explain what caused the differences in brain development in these babies, Dr. Andescavage said. But other studies have linked maternal stress and depression to changes in the newborn brain. In a future study, Dr. Andescavage and her colleagues will examine the relationship between infant brain development and how stress and anxiety during the pandemic may have played a role in early development.

Because the babies in the study were just a few weeks old, researchers don’t know if their altered brain development will affect how they learn or behave. Researchers plan to follow the children until age 6, allowing them to observe whether pandemic-era babies hit key developmental milestones on time, such as walking, talking, holding a crayon and learning the alphabet.

Researchers have been worried about the effect of COVID on the fetus since the beginning of the pandemic. Studies show that babies exposed to COVID in the womb may experience developmental impacts, and research is underway to better understand long-term outcomes.

Although the coronavirus rarely crosses the placenta to infect the fetus directly, there are other ways maternal infection can influence the developing baby. Dr. Andescavage said inflammation is one potential harm to a developing baby. In addition, if a pregnant woman becomes so sick that the levels of oxygen in her blood fall significantly, that can deprive the fetus of oxygen, she added.

In recent decades, studies of large populations have found that maternal infections with influenza and other viruses increased the risk of serious problems in children even years later, including autism, attention deficit hyperactivity disorder and schizophrenia, although the reasons behind the association are not well understood. Technology may allow doctors to answer a number of questions about COVID and the infant brain.

“With advanced imaging and MRI, we’re in a position now to be able to understand how the babies are developing in ways we never previously could,” Dr. Andescavage said. “That will better allow us to identify the exposures that may be harmful, and at what times babies may be especially vulnerable, to better position us to promote maternal wellness. This, in turn, helps infant wellness.”

Measuring preschoolers’ cognitive development in Latin America

February 13, 2024

Neurodevelopment occurs at a rapid pace during the preschool years, research shows.

Measuring and tracking development in early childhood is important for understanding how to best support long-term positive health outcomes for children. However, the art of selecting measurement tools that are appropriate for a given study sample is complex; variations in language, cultural relevance and adaptations, availability of normative data, and more can impact the administration and interpretation of study findings.

In a recent study published in the Journal of Pediatric Psychology, the authors systematically review the standardized neurodevelopmental assessments used to study preschool-aged children’s cognitive development in Spanish-speaking Latin America.

“Thinking critically about the ways we measure these outcomes is an important first step in conducting ethical and accurate global research,” said Meagan Williams, M.S.P.H., C.C.R.C., senior clinical research coordinator for the division of Infectious Diseases and the Zickler Family Prenatal Pediatrics Institute at Children’s National Hospital and corresponding author of the study.

The hold-up in the field

The field of child development research is complicated by the presence and use of many different neurodevelopmental assessment tools, only some of which are standardized and use norms to allow researchers to compare their cohorts’ performance with population-level data.

“Many cognitive assessments, including some of the most commonly used assessments identified in our review of research conducted in Spanish-speaking Latin America, have only been officially normed in the United States,” Williams added. “Others have been translated into Spanish and normed in large countries such as Mexico or Spain, but Latin America is a large and culturally diverse region, and it is unclear whether these normative samples are generalizable and culturally relevant to other regions of Spanish-speaking Latin America.”

This systematic review outlined 41 different neurodevelopmental assessments used in 97 studies, including information about each study’s sample, use of each measurement tool and findings related to child cognitive development. The review goes into detail about the most widely used assessments, including background information of each assessment and trends in how authors of the studies in this review reported their methods and results.

Moving the field forward

When researchers use similar methods and valid outcome measures across studies, it becomes possible to combine data between cohorts and draw stronger conclusions about child outcomes. For example, The Wechsler Preschool and Primary Scale of Intelligence (WPPSI) was identified as the most used tool to measure intelligence of young children ages 2-6 in the systematic review. The WPPSI is also one of many assessments that Williams’s research team, led by Sarah Mulkey, M.D., is using to measure neurodevelopment among children exposed to Zika virus in utero.

“If researchers studying longitudinal outcomes after Zika virus exposure also use the WPPSI for their study samples – and if they openly report on their methods, adaptations, and sample characteristics – then it may be possible to harmonize data from multiple cohorts and draw stronger conclusions across studies,” Williams said.

But even the most popular and widespread assessments such as the WPPSI are not without their limitations. While norms exist for regions such as the United States and Mexico, additional work needs to be done to appropriately adapt and validate these tools for use in other populations.

Benefiting patients

Neurodevelopment occurs at a rapid pace during the preschool years. The earlier neurodevelopmental delays can be identified, the earlier experts can administer interventions to respond to these delays and help children get back on track with their peers.

This is particularly salient for research conducted in low- and middle-income countries, where socioeconomic, environmental and other exposures that are known to impact child development differ from those in higher-resource settings. Internationally, there appears to be significant variability in not only the assessment tools which are selected for use, but also in the methods reported across studies to conduct and interpret these assessments.

“By coming together as a field and prioritizing the use and validation of common and culturally appropriate assessments, we can better understand child outcome data on both an individual study level as well as on a broader population level, which will lead to a better understanding of the unique needs and strengths of the children we serve,” Williams said.

The team at Children’s National has been studying the neurodevelopment of children exposed to the Zika virus in Colombia since the beginning of the Zika epidemic.

“As our study on Zika virus has overlapped with the COVID-19 pandemic, we have had the opportunity to collect child outcome data at a very interesting time in history. We are excited that this review revealed that we chose a popular and well-studied assessment for our data collection in this region and we look forward to publishing our 5-year outcome data (which will include WPPSI data) in the coming year,” Williams and Mulkey concluded.

Dr. Mulkey is committed to studying the long-term neurodevelopmental impacts that viruses like Zika and SARS-CoV-2 have on infants born to mothers who were infected during pregnancy through research with the Congenital Infection Program at Children’s National and in collaboration with colleagues in Colombia.

Children’s National performs first ever HIFU procedure on patient with cerebral palsy

February 9, 2024

HIFU is a non-invasive therapy that utilizes focused ultrasound waves to thermally ablate a focal area of tissue.

In January, a team of multidisciplinary doctors performed the first case in the world of using bilateral high intensity focused ultrasound (HIFU) pallidotomy on Jesus, a 22-year-old patient with dyskinetic cerebral palsy.

The procedure is part of a clinical trial led by Chima Oluigbo, M.D., pediatric neurosurgeon at Children’s National Hospital.

“The primary objective of the study is to evaluate the safety of ExAblate Transcranial MRgFUS as a tool for creating bilateral or unilateral lesions in the globus pallidus (GPi) in patients with treatment-refractory secondary dystonia due to dyskinetic cerebral palsy,” Dr. Oluigbo explained. “The secondary purpose is to assess the impact of HIFU pallidotomy on dyskinetic cerebral palsy movement disorder in pediatric and young adult patients.”

In addition, the impact of bilateral pallidotomy on motor development, pain perception, speech, memory, attention and cognition in these patients will be assessed.

“We hope that the trial will help us find results that lead to treatments that can reduce the rigidity and stiffness which occurs in cerebral palsy so we can help these children who do not have any effective treatment,” Dr. Oluigbo added.

“This new, first of its kind, non-invasive therapeutic approach – without even a skin incision – will open the door to offering hope for a number of kids with movement disorders who have failed conventional therapy,” said Robert Keating, M.D., chief of neurosurgery at Children’s National. “We are at the beginning of a new era for treating functional disorders in the pediatric patient.”

How it works

HIFU is a non-invasive therapy that utilizes focused ultrasound waves to thermally ablate a focal area of tissue. In the past, Children’s National successfully used HIFU to treat low-grade type tumors located in difficult locations of the brain, such as hypothalamic hamartomas and pilocytic astrocytoma, as well as for epilepsy and other movement disorders.

This most recent procedure was another successful milestone for the hospital, discharging Jesus the following day without any complications.

The team comprised neurosurgeons, MRI techs, anesthesiologists and radiologists, to name a few.

Originally, Jesus came to Children’s National in 2006 when he started working with the Physical Medicine and Rehabilitation team to help him with his muscle hypertonia management as well as equipment, orthoses and therapy concerns.

“As he continued to grow, his muscle hypertonia became more pronounced and caused difficulty with his care, positioning and comfort,” said Olga Morozova, M.D., pediatric rehabilitation specialist at Children’s National. “We have tried multiple oral medications however he has had significant side effects from the majority of the medications.”

Dr. Morozova and Julie Will, M.S.N., F.N.P., the nurse practitioner that worked with Jesus, referred him to Dr. Oluigbo after they learned about HIFU being an option to treat Jesus using a non-invasive approach.

Moving the field forward

This clinical trial highlights the expanding indications for focused ultrasound.

“We are excited about the potential for these innovative treatment strategies in neurosurgery to transform the lives of pediatric patients who suffer from challenging diseases, such as brain tumors, epilepsy, and movement disorders,” said Hasan Syed, M.D., co-director of the Focused Ultrasound Program at Children’s National. “We are redefining what is possible in neurosurgery.”

From low-intensity focused ultrasound (LIFU) treatments for our young DIPG patients to now the groundbreaking research on HIFU for pediatric movement disorders, the dedication to cutting-edge techniques highlights the team’s commitment to patients and transforming pediatric neurosurgical care.
