Children’s National Hospital in Washington, D.C., was ranked No. 7 nationally in the U.S. News & World Report 2020-21 Best Children’s Hospitals annual rankings. This marks the fourth straight year Children’s National has made the list, which ranks the top 10 children’s hospitals nationwide.
In addition, its neonatology program, which provides newborn intensive care, ranked No.1 among all children’s hospitals for the fourth year in a row.
For the tenth straight year, Children’s National also ranked in all 10 specialty services, with seven specialties ranked in the top 10.
“Our number one goal is to provide the best care possible to children. Being recognized by U.S. News as one of the best hospitals reflects the strength that comes from putting children and their families first, and we are truly honored,” says Kurt Newman, M.D., president and CEO of Children’s National Hospital.
“This year, the news is especially meaningful, because our teams — like those at hospitals across the country — faced enormous challenges and worked heroically through a global pandemic to deliver excellent care.”
“Even in the midst of a pandemic, children have healthcare needs ranging from routine vaccinations to life-saving surgery and chemotherapy,” said Ben Harder, managing editor and chief of Health Analysis at U.S. News. “The Best Children’s Hospitals rankings are designed to help parents find quality medical care for a sick child and inform families’ conversations with pediatricians.”
The annual rankings are the most comprehensive source of quality-related information on U.S. pediatric hospitals. The rankings recognize the nation’s top 50 pediatric hospitals based on a scoring system developed by U.S. News. The top 10 scorers are awarded a distinction called the Honor Roll.
The bulk of the score for each specialty service is based on quality and outcomes data. The process includes a survey of relevant specialists across the country, who are asked to list hospitals they believe provide the best care for patients with the most complex conditions.
Below are links to the seven Children’s National specialty services that U.S. News ranked in the top 10 nationally:
- Neonatology (No. 1), led by Division Chief Billie Lou Short, M.D.
- Neurology and Neurosurgery (No. 3), led by Division Chiefs William D. Gaillard, M.D., and Robert F. Keating, M.D.
- Cancer (No. 6), led by Division Chief Jeffrey S. Dome, M.D., Ph.D.
- Nephrology (No. 7), led by Division Chief Marva Moxey-Mims, M.D., FASN

The Children’s National Research Institute recently released its 2019-2020 academic annual report, titled 150 Years Stronger Through Discovery and Care to mark the hospital’s 150th birthday. Not only does the annual report give an overview of the institute’s research and education efforts, but it also gives a peek in to how the institute has mobilized to address the coronavirus pandemic.
“Our inaugural research program in 1947 began with a budget of less than $10,000 for the study of polio — a pressing health problem for Washington’s children at the time and a pandemic that many of us remember from our own childhoods,” says Vittorio Gallo, Ph.D., chief research officer at Children’s National Hospital and scientific director at Children’s National Research Institute. “Today, our research portfolio has grown to more than $75 million, and our 314 research faculty and their staff are dedicated to finding answers to many of the health challenges in childhood.”
Highlights from the Children’s National Research Institute annual report
- In 2018, Children’s National began construction of its new Research & Innovation Campus (CNRIC) on 12 acres of land transferred by the U.S. Army as part of the decommissioning of the former Walter Reed Army Medical Center campus. In 2020, construction on the CNRIC will be complete, and in 2012, the Children’s National Research Institute will begin to transition to the campus.
- In late 2019, a team of scientists led by Eric Vilain, M.D., Ph.D., director of the Center for Genetic Medicine Research, traveled to the Democratic Republic of Congo to collect samples from 60 individuals that will form the basis of a new reference genome data set. The researchers hope their project will generate better reference genome data for diverse populations, starting with those of Central African descent.
- A gift of $5.7 million received by the Center for Translational Research’s director, Lisa Guay-Woodford, M.D., will reinforce close collaboration between research and clinical care to improve the care and treatment of children with polycystic kidney disease and other inherited renal disorders.
- The Center for Neuroscience Research’s integration into the infrastructure of Children’s National Hospital has created a unique set of opportunities for scientists and clinicians to work together on pressing problems in children’s health.
- Children’s National and the National Institute of Allergy and Infectious Diseases are tackling pediatric research across three main areas of mutual interest: primary immune deficiencies, food allergies and post-Lyme disease syndrome. Their shared goal is to conduct clinical and translational research that improves what we know about those conditions and how we care for children who have them.
- An immunotherapy trial has allowed a little boy to be a kid again. In the two years since he received cellular immunotherapy, Matthew has shown no signs of a returning tumor — the longest span of time he’s been tumor-free since age 3.
- In the past 6 years, the 104 device projects that came through the National Capital Consortium for Pediatric Device Innovation accelerator program raised $148,680,256 in follow-on funding.
- Even though he’s watched more than 500 aspiring physicians pass through the Children’s National pediatric residency program, program director Dewesh Agrawal, M.D., still gets teary at every graduation.
Understanding and treating the novel coronavirus (COVID-19)
In a short period of time, Children’s National Research Institute has mobilized its scientists to address COVID-19, focusing on understanding the virus and advancing solutions to ameliorate the impact today and for future generations. Children’s National Research Institute Director Mark Batshaw, M.D., highlighted some of these efforts in the annual report:
- Eric Vilain, M.D., Ph.D., director of the Center for Genetic Medicine Research, is looking at whether or not the microbiome of bacteria in the human nasal tract acts as a defensive shield against COVID-19.
- Catherine Bollard, M.D., MBChB, director of the Center for Cancer and Immunology Research, and her team are seeing if they can “train” T cells to attack the invading coronavirus.
- Sarah Mulkey, M.D., Ph.D., an investigator in the Center for Neuroscience Research and the Fetal Medicine Institute, is studying the effects of, and possible interventions for, coronavirus on the developing brain.

We live in a time of great uncertainty yet great promise, particularly when it comes to harnessing technology to improve lives. Researchers at Children’s National Hospital are using quantitative imaging and machine intelligence to enhance care for children with a common kidney disease, and their initial results are very promising. Their technique provides an accurate way to predict earlier which children with hydronephrosis will need surgical intervention, simplifying and enhancing their care.
Hydronephrosis means “water in the kidney” and is a condition in which a kidney doesn’t empty normally. One of the most frequently detected abnormalities on prenatal ultrasound, hydronephrosis affects up to 4.5% of all pregnancies and is often discovered prenatally or just after birth.
Although hydronephrosis in children sometimes resolves by itself, identifying which kidneys are obstructed and more likely to need intervention isn’t particularly easy. But it is critical. “Children with severe hydronephrosis over long periods of time can start losing kidney function to the point of losing a kidney,” says Marius George Linguraru, DPhil, MA, MSc, principal investigator of the project; director of Precision Medical Imaging Group at the Sheikh Zayed Institute for Pediatric Surgical Innovation; and professor of radiology, pediatrics and biomedical engineering at George Washington University.
Children with hydronephrosis face three levels of examination and intervention: ultrasound, nuclear imaging testing called diuresis renogram and surgery for the critical cases. “What we want to do with this project is stratify kids as early as possible,” Dr. Linguraru says. “The earlier we can predict, the better we can plan the clinical care for these kids.”
Ultrasound is used to see whether there is a blockage and try to determine hydronephrosis severity. “Ultrasound is non-invasive, non-radiating, and does not expose the child to any risk prenatally or postnatally,” Dr. Linguraru says. Ultrasound evaluations require a trained radiologist, but there’s a lot of variability. Radiologists have a grading system based on the ultrasound appearance of the kidney to determine whether the hydronephrosis is mild, moderate or severe, but studies show this isn’t predictive of longer term outcomes.
Children whose ultrasounds show concern will be referred to diuresis renogram. Costly, complex, invasive and irradiating, it tests how well the kidney empties. Although appropriate for good clinical indications, doctors try to minimize its use. “Management of hydronephrosis is complex,” Dr. Linguraru says. “We want to use ultrasound as much as possible and much less diuresis renogram.”
For those patients whose kidney is obstructed and eventually need surgical intervention, the sooner that decision can be made the better. “The more you wait for a kidney that is severely obstructed, the more function may be lost. If intervention is required, it’s preferable to do it early,” Dr. Linguraru says. Of course for the child whose hydronephrosis will likely resolve itself, intervention is not the best option.
Dr. Linguraru and the multidisciplinary team at Children’s National Hospital, including radiology and urology clinicians, are putting the power of computers to work interpreting subtleties in the ultrasound data that humans just can’t see. In their pilot study they found that 60% of the nuclear imaging tests could have been safely avoided without missing any of the critical cases of hydronephrosis. “With our technique we are measuring physiological and anatomical changes in the ultrasound image of the kidney,” Dr. Linguraru says. “The human eye may find it difficult to put all this together, but the machine can do it. We use quantitative imaging to do deep phenotyping of the kidney and machine learning to interpret the data.”
Results of the initial study indicate that kids who have a mild condition can be safely discharged earlier and the model can predict all those kids with obstructions and accelerate their diagnosis by sending them earlier to get further investigation. Dr. Linguraru says. “There are only benefits: some kids will get earlier diagnosis, some earlier discharges.”
The team also has a way to improve the interpretation of diuresis renograms. “We analyze the dynamics of the kidney’s drainage curve in quantifiable way. Using machine learning to interpret those results, we showed we can potentially discharge some kids earlier and accelerate intervention for the most severe cases instead of waiting and repeating the invasive tests,” he says. The framework has 93% accuracy, including 91% sensitivity and 96% specificity, to predict surgical cases, a significant improvement over clinical metrics’ accuracy.
The next step is a study connecting all the protocols. “Right now we have a study on ultrasound, a study on nuclear imaging, but we need to connect them so a child with hydronephrosis immediately benefits,” says Dr. Linguraru. Future work will focus on streamlining and accelerating diagnosis and intervention for kids who need it, both in prospective studies and hopefully clinically as well.
Hydronephrosis is an area in which machine learning can be applied to pediatric health in meaningful ways because of the sheer volume of cases.
“Machine learning algorithms work best when they are trained well on a lot of data,” Dr. Linguraru says. “Often in pediatric conditions, data are sparse because conditions are rare. Hydronephrosis is one of those areas that can really benefit from this new technological development because there is a big volume of patients. We are collecting more data, and we’re becoming smarter with these kinds of algorithms.”

Children with kidney disease have very special diet and nutrition needs. In order to stay healthy, most children with kidney disease have to limit or avoid foods that are high in certain minerals including sodium, potassium and phosphorus. It is often challenging for children and their families to balance following these diet restrictions with getting proper nutrition and enjoying meal times.
As an innovative way to facilitate adherence to these limitations, our nephrology department collaborated with our patient families to create a cookbook “Keeping it Renal: Global Cuisine for Kids,” a compilation of their favorite kidney-friendly recipes.
Children’s National is one of the top pediatric hospitals in NIH funding, and our nephrology program ranks number 6 in the country, according to U.S. News & World Report. The Kidney Transplantation Program is the only one of its kind in the Washington, D.C. area focused on the needs of children and teens with kidney disease. Committed to providing the best quality care to all of our pediatric transplant patients, we are always looking for new ways to support our patient families.

More than 30 million Americans have diabetes, with the vast majority having Type 2 disease. Characterized by insulin resistance and persistently high blood sugar levels, poorly controlled Type 2 diabetes has a host of well-recognized complications: compared with the general population, a greatly increased risk of kidney disease, vision loss, heart attacks and strokes and lower limb amputations.
But more recently, says Nathan A. Smith, MS, Ph.D., a principal investigator in Children’s National Research Institute’s Center for Neuroscience Research, another consequence has become increasingly apparent. With increasing insulin resistance comes cognitive damage, a factor that contributes significantly to dementia diagnoses as patients age.
The brain comprises only 2% of the body’s volume, but it uses more than 20% of its energy, Smith explains – which makes this organ particularly vulnerable to changes in metabolism. Type 2 diabetes and even prediabetic changes in glucose metabolism inflict damage upon this organ in mechanisms with dangerous synergy, he adds. Insulin resistance itself stresses brain cells, slowly depriving them of fuel. As blood sugar rises, it also increases inflammation and blocks nitric oxide, which together narrow the brain’s blood vessels while also increasing blood viscosity.
When the brain’s neurons slowly starve, they become increasingly inefficient at doing their job, eventually succumbing to this deprivation. These hits don’t just affect individual cells, Smith adds. They also affect connectivity that spans across the brain, neural networks that are a major focus of his research.
While it’s well established that Type 2 diabetes significantly boosts the risk of cognitive decline, Smith says, it’s been unclear whether this process might be halted or even reversed. It’s this question that forms the basis of a collaborative Frontiers grant, $2.5 million from the National Science Foundation split between his laboratory; the lead institution, Stony Brook University; and Massachusetts General Hospital/Harvard Medical School.
Smith and colleagues at the three institutions are testing whether changing the brain’s fuel source from glucose to ketones – byproducts from fat metabolism – could potentially save neurons and neural networks over time. Ketones already have shown promise for decades in treating some types of epilepsy, a disease that sometimes stems from an imbalance in neuronal excitation and inhibition. When some patients start on a ketogenic diet – an extreme version of a popular fat-based diet – many can significantly decrease or even stop their seizures, bringing their misfiring brain cells back to health.
Principal Investigator Smith and his laboratory at the Children’s National Research Institute are using experimental models to test whether ketones could protect the brain against the ravages of insulin resistance. They’re looking specifically at interneurons, the inhibitory cells of the brain and the most energy demanding. The team is using a technique known as patch clamping to determine how either insulin resistance or insulin resistance in the presence of ketones affect these cells’ ability to fire.
They’re also looking at how calcium ions migrate in and out of the cells’ membranes, a necessary prerequisite for neurons’ electrical activity. Finally, they’re evaluating whether these potential changes to the cells’ electrophysiological properties in turn change how different parts of the brain communicate with each other, potentially restructuring the networks that are vital to every action this organ performs.
Colleagues at Athinoula A. Martinos Center for Biomedical Imaging at Massachusetts General Hospital and Harvard Medical School, led by Principal Investigator Eva-Maria Ratai, Ph.D., will perform parallel work in human subjects. They will use imaging to determine how these two fuel types, glucose or ketones, affect how the brain uses energy and produces the communication molecules known as neurotransmitters. They’re also investigating how these factors might affect the stability of neural networks using techniques that investigate the performance of these networks both while study subjects are at rest and performing a task.
Finally, colleagues at the Laufer Center for Physical and Quantitative Biology at Stony Brook University, led by Principal Investigator Lilianne R. Mujica-Parodi, Ph.D., will use results generated at the other two institutions to construct computational models that can accurately predict how the brain will behave under metabolic stress: how it copes when deprived of fuel and whether it might be able to retain healthy function when its cells receive ketones instead of glucose.
Collectively, Smith says, these results could help retain brain function even under glucose restraints. (For this, the research team owes a special thanks to Mujica-Parodi, who assembled the group to answer this important question, thus underscoring the importance of team science, he adds.)
“By supplying an alternate fuel source, we may eventually be able to preserve the brain even in the face of insulin resistance,” Smith says.
Recently, Kurt Newman, M.D., president and CEO of Children’s National Hospital, authored an opinion piece for the popular political website, The Hill. In the article, he called upon stakeholders from across the landscape to address the significant innovation gap in children’s healthcare versus adults.
As Chair of the Board of Trustees of the Children’s Hospital Association, Dr. Newman knows the importance of raising awareness among policy makers at the federal and state level about the healthcare needs of children. Dr. Newman believes that children’s health should be a national priority that is addressed comprehensively. With years of experience as a pediatric surgeon, he is concerned by the major inequities in the advancements of children’s medical devices and technologies versus those for adults. That’s why Children’s National is working to create collaborations, influence policies and facilitate changes that will accelerate the pace of pediatric healthcare innovation for the benefit of children everywhere. One way that the hospital is tackling this challenge is by developing the Children’s National Research & Innovation Campus, which will be the nation’s first innovation campus focused on pediatric research.
Children’s National Hospital and Virginia Tech create formal partnership that includes the launch of a Virginia Tech biomedical research facility within the new Children’s National Research & Innovation Campus.
Children’s National Hospital and Virginia Tech recently announced a formal partnership that will include the launch of a 12,000-square-foot Virginia Tech biomedical research facility within the new Children’s National Research & Innovation Campus. The campus is an expansion of Children’s National that is located on a nearly 12-acre portion of the former Walter Reed Army Medical Center in Washington, D.C. and is set to open its first phase in December 2020. This new collaboration brings together Virginia Tech, a top tier academic research institution, with Children’s National, a U.S. News and World Report top 10 children’s hospital, on what will be the nation’s first innovation campus focused on pediatric research.
“Virginia Tech is an ideal partner to help us deliver on what we promised for the Children’s National Research & Innovation Campus – an ecosystem that enables us to accelerate the translation of potential breakthrough discoveries into new treatments and technologies,” says Kurt Newman, M.D., president and CEO, Children’s National. “Our clinical expertise combined with Virginia Tech’s leadership in engineering and technology, and its growing emphasis on biomedical research, will be a significant advance in developing much needed treatment and cures to save children’s lives.”
Earlier this year, Children’s National announced a collaboration with Johnson & Johnson Innovation LLC to launch JLABS @ Washington, DC at the Research & Innovation Campus. The JLABS @ Washington, DC site will be open to pharmaceutical, medical device, consumer and health technology companies that are aiming to advance the development of new drugs, medical devices, precision diagnostics and health technologies, including applications in pediatrics.
“We are proud to welcome Virginia Tech to our historic Walter Reed campus – a campus that is shaping up to host some of the top minds, talent and innovation incubators in the world,” says Washington, D.C. Mayor Muriel Bowser. “The new Children’s National Research & Innovation Campus will exemplify why D.C. is the capital of inclusive innovation – because we are a city committed to building the public and private partnerships necessary to drive discoveries, create jobs, promote economic growth and keep D.C. at the forefront of innovation and change.”
Faculty from the Children’s National Research Institute and the Fralin Biomedical Research Institute at Virginia Tech Carilion (VTC) have worked together for more than a decade, already resulting in shared research grants, collaborative publications and shared intellectual property. Together, the two institutions will now expand their collaborations to develop new drugs, medical devices, software applications and other novel treatments for cancer, rare diseases and other disorders.
“Joining with Children’s National in the nation’s capital positions Virginia Tech to improve the health and well-being of infants and children around the world,” says Virginia Tech President Tim Sands, Ph.D. “This partnership resonates with our land-grant mission to solve big problems and create new opportunities in Virginia and D.C. through education, technology and research.”
The partnership with Children’s National adds to Virginia Tech’s growing footprint in the Washington D.C. region, which includes plans for a new graduate campus in Alexandria, Va. with a human-centered approach to technological innovation. Sands said the proximity of the two locations – just across the Potomac – will enable researchers to leverage resources, and will also create opportunities with the Virginia Tech campus in Blacksburg, Va. and the Virginia Tech Carilion Health Science and Technology campus in Roanoke, Va.
Carilion Clinic and Children’s National have an existing collaboration for provision of certain specialized pediatric clinical services. The more formalized partnership between Virginia Tech and Children’s National will drive the already strong Virginia Tech-Carilion Clinic partnership, particularly for children’s health initiatives and facilitate collaborations between all three institutions in the pediatric research and clinical service domains.
Children’s National and Virginia Tech will engage in joint faculty recruiting, joint intellectual property, joint training of students and fellows, and collaborative research projects and programs according to Michael Friedlander, Ph.D., Virginia Tech’s vice president for health sciences and technology, and executive director of the Fralin Biomedical Research Institute at VTC.
“The expansion and formalization of our partnership with Children’s National is extremely timely and vital for pediatric research innovation and for translating these innovations into practice to prevent, treat and ultimately cure nervous system cancer in children,” says Friedlander, who has collaborated with Children’s National leaders and researchers for more than 20 years. “Both Virginia Tech and Children’s National have similar values and cultures with a firm commitment to discovery and innovation in the service of society.”
“Brain and other nervous system cancers are among the most common cancers in children (alongside leukemia),” says Friedlander. “With our strength in neurobiology including adult brain cancer research in both humans and companion animals at Virginia Tech and the strength of Children’s National research in pediatric cancer, developmental neuroscience and intellectual disabilities, this is a perfect match.”
The design of the Children’s National Research & Innovation Campus not only makes it conducive for the hospital to strengthen its prestigious partnerships with Virginia Tech and Johnson & Johnson, it also fosters synergies with federal agencies like the Biomedical Advanced Research and Development Authority, which will collaborate with JLABS @ Washington, DC to establish a specialized innovation zone to develop responses to health security threats. As more partners sign on, this convergence of key public and private institutions will accelerate discoveries and bring them to market faster for the benefit of children and adults.
“The Children’s National Research & Innovation Campus pairs an inspirational mission to find new treatments for childhood illness and disease with the ideal environment for early stage companies. I am confident the campus will be a magnet for big ideas and will be an economic boost for Washington DC and the region,” says Jeff Zients, who was appointed chair of the Children’s National Board of Directors effective October 1, 2019. As a CEO and the former director of President Obama’s National Economic Council, Zients says that “When you bring together business, academia, health care and government in the right setting, you create a hotbed for innovation.”
Ranked 7th in National Institutes of Health research funding among pediatric hospitals, Children’s National continues to foster collaborations as it prepares to open its first 158,000-square-foot phase of its Research & Innovation Campus. These key partnerships will enable the hospital to fulfill its mission of keeping children top of mind for healthcare innovation and research while also contributing to Washington D.C.’s thriving innovation economy.
When Lisa M. Guay-Woodford, M.D., McGehee Joyce Professor of Pediatrics at Children’s National Hospital, considers a brand-new gift, she likens it to 6 million gallons of “rocket fuel” that will power new research to better understand polycystic kidney disease.
Dr. Guay-Woodford received a $5.7 million dollar gift to support PKD clinical and research activities. PKD is a genetic disorder characterized by clusters of fluid-filled sacs (cysts) multiplying and interfering with the kidneys’ ability to filter waste from the blood. The kidneys’ smooth surface transforms to a bumpy texture as the essential organs grow oversized and riddled with cysts.
The extraordinary generosity got its start in an ordinary clinical visit.
Dr. Guay-Woodford saw a young patient in her clinic at Children’s National a few times in 2015. The child’s diagnosis sparked a voyage of discovery for the patient’s extended family and, ultimately, they attended a presentation she gave during a regional meeting about PKD. That led to a telephone conversation and in-person meeting as they invited her to describe “the white space” between what was being done at the time to better understand PKD and what could be done.
“It’s the power of the art and science of medicine. They come to see people like me because of the science. If we can convey to patients and families that who they are and their unique concerns are really important to researchers, that becomes a powerful connection,” she says. “The art plus the science equals hope. That is what these families are looking for: We give people the latest insights about their disease because information is power.”
The infusion of new funding will strengthen the global initiative’s four pillars:
- Coordinated care for children and families impacted by renal cystic disease. The Inherited and Polycystic Kidney Disease (IPKD) program, launched September 2019, includes a cadre of experts working together as a team in the medical home so that “in a single, one-stop visit, Children’s National can address the myriad concerns they have,” she explains. A multi-disciplinary team that includes nephrologists, hepatologists and endocrinology experts meets weekly to ensure the Center of Excellence provides the highest-caliber patient care. The team includes genetic counselors to empower families with knowledge about genetic risks and testing opportunities. A nurse helps families navigate the maze of who to call about which issue. Psychologists help to ease anxiety. “There is stress. There is fear. There is pain that can be associated with this set of diseases. The good news is we can control their medical issues. The bad news is some children have difficulty coping. Our psychologists help children cope so they can be a child and do the normal things that children do,” she says.
- Strengthening global databases to capture PKD variations. The team will expand its outreach to other centers located around the world – including Australia, Europe, India and Latin America – caring for patients with both the recessive and dominant forms of polycystic kidney disease, to better understand the variety of ways the disease can manifest in children. “We really don’t know a lot about kids with the dominant form of the disease. How hard should we push to control their blood pressure, knowing that could ease symptoms? What are the ramifications of experiencing acute pain compared with chronic pain? How much do these pain flareups interfere with daily life and a child’s sense of self,” she asks. Capturing the nuances of the worldwide experience offers the power of harnessing even more data. And ensuring that teams collect data in a consistent way means each group would have the potential to extract the most useful information from database queries.
- Filling a ‘desperate need’ for biomarkers. Developing clinical trials for new therapies requires having biomarkers that indicate the disease course. Such biomarkers have been instrumental in personalizing care for patients with other chronic conditions. “We are in desperate need for such biomarkers, and this new funding will underwrite pilot studies to identify and validate these disease markers. The first bite at the apple will leverage our imaging data to identify promising biomarkers,” she says.
- Genetic mechanisms that trigger kidney disease. About 500,000 people in the U.S. have PKD. In many cases, children inherit a genetic mutation but, often, their genetic mutation develops spontaneously. Dr. Guay-Woodford’s research about the mechanisms that make certain inherited renal disorders lethal, such as autosomal recessive polycystic kidney disease, is recognized around the world. The fourth pillar of the new project provides funding to continue her lab’s research efforts to improve the mechanistic understanding of what triggers PKD.
Adolescents with Type 2 diabetes experienced more hyperfiltration and earlier attenuation of their elevated urine albumin-to-creatinine ratio (UACR) after gastric bypass surgery compared with adults. This finding contrasts with adolescents or adults who did not have diabetes prior to surgery, according to research presented Nov. 8, 2019, during the American Society of Nephrology’s Kidney Week 2019, the world’s largest gathering of kidney researchers.
“Findings from this work support a recent policy statement by the American Academy of Pediatrics (AAP) that advocates for increasing severely obese youths’ access to bariatric surgery,” says Marva Moxey-Mims, M.D., Chief of the Division of Nephrology at Children’s National Hospital and a study co-author. “We know that bariatric surgery improves markers of kidney health in severely obese adults and adolescents. This research helps to elucidate possible differences in kidney disease outcomes between children and adults post-surgery.”
According to the AAP, the prevalence of severe obesity in youth aged 12 to 19 has nearly doubled since 1999. Now, 4.5 million U.S. children are affected by severe obesity, defined as having a body mass index ≥35 or ≥120% of the 95th percentile for age and sex.
In a Roux-en-Y gastric bypass, the surgeon staples the stomach to make it smaller, so people eat less. Then, they attach the lower part of the small intestine in a way that bypasses most of the stomach so the body takes in fewer calories.
The multi-institutional study team examined the health effects of such gastric bypass surgeries by comparing 161 adolescents with 396 adults enrolled in related studies. They compared their estimated glomerular filtration rates by serum creatinine and cystatin C. UACR was also compared at various time periods, up till five years after surgery.
Across the board, adolescents had higher UACR – a key marker for chronic kidney disease – than adults. However, for kids who had Type 2 diabetes prior to surgery, the prevalence of elevated UACR levels dip from 29% pre-surgery to 6% one year post-surgery. By contrast, adults who had diabetes prior to surgery and elevated UACR did not see a significant reduction in UACR until five years post-surgery.
While hyperfiltration prevalence was similar in study participants who did not have Type 2 diabetes, adolescents who had Type 2 diabetes prior to surgery had an increased prevalence of hyperfiltration for the duration of the study period.
Financial support for research described in this post was provided by the National Institute of Diabetes and Digestive and Kidney Diseases.

Mihailo Kaplarevic, Ph.D., the newly minted Chief Research Information Officer at Children’s National Hospital and Bioinformatics Division Chief at Children’s National Research Institute, will provide computational support, advice, informational guidance, expertise in big data and data analyses for researchers and clinicians.
Kaplarevic’s new job is much like the role he played most recently at the National Heart, Lung and Blood Institute (NHLBI), assembling a team of researchers and scientists skilled in computing and statistical analyses to assist as in-house experts for other researchers and scientists.
NHLBI was the first institute within the National Institutes of Health (NIH) family to set up a scientific information office. During his tenure, a half-dozen other NIH institutions followed, setting up the same entity to help bridge the enormous gap between basic and clinical science and everything related to IT.
“There is a difference compared with traditional IT support at Children’s National – which will remain in place and still do the same sort of things they have been doing so far,” he says of The Bear Institute for Health Innovation. “The difference is this office has experience in research because every single one of us was a researcher at a certain point in our career: We are published. We applied for grants. We lived the life of a typical scientist. On top of that, we’re coming from the computational world. That helps us bridge the gaps between research and clinical worlds and IT.”
Ultimately, he aims to foster groundbreaking science by recognizing the potential to enhance research projects by bringing expertise acquired over his career and powerful computing tools to help teams achieve their goals in a less expensive and more efficient way.
“I have lived the life of a typical scientist. I know exactly how painful and frustrating it can be to want to do something quickly and efficiently but be slowed by technological barriers,” he adds.
As just one example, his office will design the high-performance computing cluster for the hospital to help teams extract more useful clinical and research data with fewer headaches.
Right now, the hospital has three independent clinical systems storing patient data; all serve a different purpose. (And there are also a couple of research information systems, also used for different purposes.) Since databases are his expertise, he will be involved in consolidating data resources, finding the best way to infuse the project with the bigger-picture mission – especially for translational science – and creating meaningful, actionable reports.
“It’s not only about running fewer queries,” he explains. “One needs to know how to design the right question. One needs to know how to design that question in a way that the systems could understand. And, once you get the data back, it’s a big set of things that you need to further filter and carefully shape. Only then will you get the essence that has clinical or scientific value. It’s a long process.”
As he was introduced during a Children’s National Research Institute faculty meeting in late-September 2019, Kaplarevic joked that his move away from pure computer science into a health care and clinical research domain was triggered by his parents: “When my mom would introduce me, she would say ‘My son is a doctor, but not the kind of doctor who helps other people.’ ”
Some of that know-how will play out by applying tools and methodology to analyze big data to pluck out the wheat (useful data) from the chaff in an efficient and useful way. On projects that involve leveraging cloud computing for storing massive amounts of data, it could entail analyzing the data wisely to reduce its size when it comes back from the cloud – when the real storage costs come in. “You can save a lot of money by being smart about how you analyze data,” he says.
While he expects his first few months will be spent getting the lay of the land, understanding research project portfolios, key principal investigators and the pediatric hospital’s biggest users in the computational domain, he has ambitious longer-term goals.
“Three years from now, I would like this institution to say that the researchers are feeling confident that their research is not affected by limitations related to computer science in general. I would like this place to become a very attractive environment for up-and-coming researchers as well as for established researchers because we are offering cutting-edge technological efficiencies; we are following the trends; we are a secure place; and we foster science in the best possible way by making computational services accessible, affordable and reliable.”
Lee Savio Beers, M.D., FAAP, Medical Director of Community Health and Advocacy at the Child Health Advocacy Institute (CHAI) at Children’s National Hospital carved out a Monday morning in late-September 2019, as she knew the American Academy of Pediatrics (AAP) would announce the results of its presidential election, first by telephone call, then by an email to all of its members. Her husband blocked off the morning as well to wait with her for the results. She soon got the call that she was elected by her peers to become AAP president-elect, beginning Jan. 1, 2020. Dr. Beers will then serve as AAP president in 2021 for a one-year term.
That day swept by in a rush, and then the next day she was back in clinic, caring for her patients, some of them teenagers whom she had taken care of since birth. Seeing children and families she had known for such a long time, some of whom had complex medical needs, was a perfect reminder of what originally motivated Dr. Beers to be considered as a candidate in the election.
“When we all work together – with our colleagues, other professionals, communities and families – we can make a real difference in the lives of children. So many people have reached out to share their congratulations, and offer their support or help. There is a real sense of collaboration and commitment to child health,” Dr. Beers says.
That sense of excitement ripples through Children’s National.
“Dr. Beers has devoted her career to helping children. She has developed a national advocacy platform for children. I can think of no better selection for the president-elect role of the AAP. She will be of tremendous service to children within AAP national leadership,” says Kurt Newman, M.D., Children’s National Hospital President and CEO.
AAP comprises 67,000 pediatricians, and its mission is to promote and safeguard the health and well-being of all children – from infancy to adulthood.
The daughter of a nuclear engineer and a schoolteacher, Dr. Beers knew by age 5 that she would become a doctor. Trained as a chemist, she entered the Emory University School of Medicine after graduation. After completing residency at the Naval Medical Center, she became the only pediatrician assigned to the Guantanamo Bay Naval Station.
That assignment to Cuba, occurring so early in her career, turned out to be a defining moment that shapes how she partners with families and other members of the team to provide comprehensive care.
“I was a brand-new physician, straight out of residency, and was the only pediatrician there so I was responsible for the health of all of the kids on the base. I didn’t know it would be this way at the time, but it was formative. It taught me to take a comprehensive public health approach to taking care of kids and their families,” she recalls.
On the isolated base, where she also ran the immunization clinic and the nursery, she quickly learned she had to judiciously use resources and work together as a team.
“It meant that I had to learn how to lead a multi-disciplinary team and think about how our health care systems support or get in the way of good care,” she says.
One common thread that unites her past and present is helping families build resiliency to shrug off adversity and stress.
“The base was a difficult and isolated place for some families and individuals, so I thought a lot about how to support them. One way is finding strong relationships where you are, which was important for patients and families miles away from their support systems. Another way is to find things you could do that were meaningful to you.”
Cuba sits where the Atlantic Ocean, Caribbean Sea and Gulf of Mexico meet. Dr. Beers learned how to scuba dive there – something she never would have done otherwise – finding it restful and restorative to appreciate the underwater beauty.
“I do think these lessons about resilience are universal. There are actually a lot of similarities between the families I take care of now, many of whom are in socioeconomically vulnerable situations, and military families when you think about the level of stress they are exposed to,” she adds.
Back stateside in 2001, Dr. Beers worked as a staff pediatrician at the National Naval Medical Center in Bethesda, Maryland, and Walter Reed Army Medical Center in Washington, D.C. In 2003, Dr. Beers joined Children’s National Hospital as a general pediatrician in the Goldberg Center for Community Pediatric Health. Currently, she oversees the DC Collaborative for Mental Health in Pediatric Primary Care, a public-private coalition that elevates the standards of mental health care for all children, and is Co-Director of the Early Childhood Innovation Network. She received the Academic Pediatric Association’s 2019 Public Policy and Advocacy Award.
As a candidate, Dr. Beers pledged to continue AAP’s advocacy and public policy efforts and to further enhance membership diversity and inclusion. Among her signature issues:
- Partnering with patients, families, communities, mental health providers and pediatricians to co-design systems to bolster children’s resiliency and to alleviate growing pediatric mental health concerns
- Tackling physician burnout by supporting pediatricians through office-based education and systems reforms
- Expanding community-based prevention and treatment
“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 that pediatricians can accomplish by working together toward common strategic goals.”
AAP isn’t just an integral part of her life, it’s where she met her future husband, Nathaniel Beers, M.D., MPA, FAAP, President of The HSC Health Care System. The couple’s children regularly attended AAP meetings with them when they were young.
Just take a glimpse at Lee Beers’ Twitter news feed. There’s a steady stream of images of her jogging before AAP meetings to amazing sunrises, jogging after AAP meetings to stellar sunsets and always, always, images of the entire family, once collectively costumed as The Incredibles.
“I really do believe that we have to set an example: If we are talking about supporting children and families in our work, we have to set that example in our own lives. That looks different for everyone, but as pediatricians and health professionals, we can model prioritizing our families while still being committed to our work,” she explains.
“Being together in the midst of the craziness is just part of what we do as a family. We travel a lot, and our kids have gone with us to AAP meetings since they were infants. My husband even brought our infant son to a meeting at the mayor’s office when he was on paternity leave. Recognizing that not everyone is in a position to be able to do things like that, it’s important for us to do it – to continue to change the conversation and make it normal to have your family to be part of your whole life, not have a separate work life and a separate family life.”
Children’s National in Washington, D.C., is the nation’s No. 6 children’s hospital and, for the third year in a row, its neonatology program is No.1 among all children’s hospitals providing newborn intensive care, according to the U.S. News Best Children’s Hospitals annual rankings for 2019-20.
This is also the third year in a row that Children’s National has been in the top 10 of these national rankings. It is the ninth straight year it has ranked in all 10 specialty services, with five specialty service areas ranked among the top 10.
“I’m proud that our rankings continue to cement our standing as among the best children’s hospitals in the nation,” says Kurt Newman, M.D., President and CEO for Children’s National. “In addition to these service lines, today’s recognition honors countless specialists and support staff who provide unparalleled, multidisciplinary patient care. Quality care is a function of every team member performing their role well, so I credit every member of the Children’s National team for this continued high performance.”
The annual rankings recognize the nation’s top 50 pediatric facilities based on a scoring system developed by U.S. News. The top 10 scorers are awarded a distinction called the Honor Roll.
“The top 10 pediatric centers on this year’s Best Children’s Hospitals Honor Roll deliver outstanding care across a range of specialties and deserve to be nationally recognized,” says Ben Harder, chief of health analysis at U.S. News. “According to our analysis, these Honor Roll hospitals provide state-of-the-art medical expertise to children with rare or complex conditions. Their rankings reflect U.S. News’ assessment of their commitment to providing high-quality, compassionate care to young patients and their families day in and day out.”
The bulk of the score for each specialty is based on quality and outcomes data. The process also includes a survey of relevant specialists across the country, who are asked to list hospitals they believe provide the best care for patients with challenging conditions.
Below are links to the five specialty services that U.S. News ranked in the top 10 nationally:
- Neonatology (No. 1), led by Division Chief Billie Lou Short, M.D.
- Neurology and Neurosurgery (No. 5), led by Division Chiefs Roger J. Packer, M.D., and Robert F. Keating, M.D.
- Nephrology (No. 6), led by Division Chief Marva Moxey-Mims, M.D., FASN
- Cancer (No. 9), led by Division Chief Jeffrey S. Dome, M.D., Ph.D., and
- Pulmonology and lung surgery (No.9), led by Division Chief Anastassios Koumbourlis, M.D., MPH
Vittorio Gallo, Ph.D., Chief Research Officer at Children’s National, was inducted into Alpha Omega Alpha (AΩA), a national medical honor society that since 1902 has recognized excellence, leadership and research in the medical profession.
“I think it’s great to receive this recognition. I was very excited and surprised,” Gallo says of being nominated to join the honor society.
“Traditionally AΩA membership is based on professionalism, academic and clinical excellence, research, and community service – all in the name of ‘being worthy to serve the suffering,’ which is what the Greek letters AΩA stand for,” says Panagiotis Kratimenos, M.D., Ph.D., an ΑΩΑ member and attending neonatologist at Children’s National who conducts neuroscience research under Gallo’s mentorship. Dr. Kratimenos nominated his mentor for induction.
“Being his mentee, I thought Gallo was an excellent choice for AΩΑ faculty member,” Dr. Kratimenos says. “He is an outstanding scientist, an excellent mentor and his research is focused on improving the quality of life of children with brain injury and developmental disabilities – so he serves the suffering. He also has mentored numerous physicians over the course of his career.”
Gallo’s formal induction occurred in late May 2019, just prior to the medical school graduation at the George Washington University School of Medicine & Health Sciences (GWSMHS) and was strongly supported by Jeffrey S. Akman, Vice President for Health Affairs and Dean of the university’s medical school.
“I’ve been part of Children’s National and in the medical field for almost 18 years. That’s what I’m passionate about: being able to enhance translational research in a clinical environment,” Gallo says. “In a way, this recognition from the medical field is a perfect match for what I do. As Chief Research Officer at Children’s National, I am charged with continuing to expand our research program in one of the top U.S. children’s hospitals. And, as Associate Dean for Child Health Research at GWSMHS, I enhance research collaboration between the two institutions.”
After receiving a kidney transplant, children may experience quality-of-life difficulties that underscore the importance of screening transplant recipients for psychosocial function, according to Children’s research presented May 4, 2019, during the 10th Congress of the International Pediatric Transplant Association.
About 2,000 children and adolescents younger than 18 are on the national waiting list for an organ transplant, according to the Department of Health and Human Services, with most infants and school-aged children waiting for a heart, liver or kidney and most children older than 11 waiting for a kidney or liver. In 2018, 1,895 U.S. children received transplants.
The research team at Children’s National wanted to hear directly from kids about their quality of life after kidney transplant in order to tailor timely interventions to children. Generally, recipients of kidney transplants have reported impaired quality of life compared with healthy peers, with higher mental health difficulties, disrupted sleep patterns and lingering pain.
The Children’s team measured general health-related quality of life using a 23-item PedsQL Generic Core module and measured transplant-related quality of life using the PedsQL- Transplant Module. The forms, which can be used for patients as young as 2, take about five to 10 minutes to complete and were provided to the child, the parent or the primary care giver – as appropriate – during a follow-up visit after the transplant.
Thirty-three patient-parent dyads completed the measures, with an additional 25 reports obtained from either the patient or the parent. The patients’ mean age was 14.2; 41.4% were female.
“Overall, children who receive kidney transplants had minimal concerns about quality of life after their operation. While it’s comforting that most pediatric patients had no significant problems, the range of quality of life scores indicate that some patients had remarkable difficulties,” says Kaushalendra Amatya, Ph.D., a pediatric psychologist in Nephrology and Cardiology at Children’s National and the study’s lead author.
When the study team reviewed reports given by parents, they found their descriptions sometimes differed in striking ways from the children’s answers.
“Parents report lower values on emotional functioning, social functioning and total core quality of life, indicating that parents perceive their children as having more difficulties across these specific domains than the patients’ own self reports do,” Amatya adds.

Children who developed anti-human leukocyte antibodies against their donor kidney, known as de novo donor-specific antibodies (dnDSA), after kidney transplant were more likely to experience carotid intima-media thickening (CIMT) than those without these antibodies, according to preliminary research presented May 7, 2019, during the 10th Congress of the International Pediatric Transplant Association.
dnDSA play a key role in the survival of a transplanted organ. While human leukocyte antibodies protect the body from infection, dnDSA are a major cause of allograft loss. CIMT measures the thickness of the intima and media layers of the carotid artery and can serve as an early marker of cardiac disease.
Emerging evidence links dnDSA with increased risk of accelerated systemic hardening of the arteries (arteriosclerosis) and major cardiac events in adult organ transplant recipients. However, this phenomenon has not been studied extensively in children who receive kidney transplants.
To investigate the issue, Children’s researchers enrolled 38 children who had received kidney transplants and matched them by race with 20 healthy children. They measured their CIMT, blood pressure and lipids 18 months and 30 months after their kidney transplants. They monitored dnDSA at 18 months and 30 months after kidney transplant. The transplant recipients’ median age was 11.3 years, 50 percent were African American, and 21% developed dnDSA.
“In this prospective controlled cohort study, we compared outcomes among patients who developed dnDSA with transplant recipients who did not develop dnDSA and with race-matched healthy kids,” says Kristen Sgambat, Ph.D., a pediatric renal dietitian at Children’s National who was the study’s lead author. “Children with dnDSA after transplant had 5.5% thicker CIMT than those who did not have dnDSA. Being African American was also independently associated with a 9.2% increase in CIMT among transplant recipients.”
Additional studies will need to be conducted in larger numbers of pediatric kidney transplant recipients to verify this preliminary association, Sgambat adds.

People joke that Billie Lou Short, M.D., chief of Children’s Division of Neonatology, invented extracorporeal membrane oxygenation, known as ECMO for short. While Dr. Short did not invent ECMO, under her leadership Children’s National was the first pediatric hospital to use it. And over decades Children’s staff have perfected its use to save the lives of tiny, vulnerable newborns by temporarily taking over for their struggling hearts and lungs. For two consecutive years, Children’s neonatal intensive care unit has been named the nation’s No. 1 for newborns by U.S. News & World Report. “Despite all of these accomplishments, Dr. Short’s best legacy is what she has done as a mentor to countless trainees, nurses and faculty she’s touched during their careers. She touches every type of clinical staff member who has come through our neonatal intensive care unit,” says An Massaro, M.D., director of residency research.
For these achievements, Dr. Short received the Ninth Annual Mentorship Award in Clinical Science.
Anna Penn, M.D., Ph.D., has provided new insights into the central role that the placental hormone allopregnanolone plays in orderly fetal brain development, and her research team has created novel experimental models that mimic some of the brain injuries often seen in very preterm babies – an essential step that informs future neuroprotective strategies. Dr. Penn, a clinical neonatologist and developmental neuroscientist, “has been a primary adviser for 40 mentees throughout their careers and embodies Children’s core values of Compassion, Commitment and Connection,” says Claire-Marie Vacher, Ph.D.
For these achievements, Dr. Penn was selected to receive the Ninth Annual Mentorship Award in Basic and Translational Science.
The mentorship awards for Drs. Short and Penn were among dozens of honors given in conjunction with “Frontiers in Innovation,” the Ninth Annual Research and Education Week (REW) at Children’s National. In addition to seven keynote lectures, more than 350 posters were submitted from researchers – from high-school students to full-time faculty – about basic and translational science, clinical research, community-based research, education, training and quality improvement; five poster presenters were showcased via Facebook Live events hosted by Children’s Hospital Foundation.

Quick. Name four pillar pediatric organizations on the vanguard of advancing pediatric research.
Most researchers and clinicians can rattle off the names of the Academic Pediatric Association, the American Academy of Pediatrics and the American Pediatric Society. But that fourth one, the Society for Pediatric Research (SPR), is a little trickier. While many know SPR, a lot of research-clinicians simply do not.
Over the next few years, Beth A. Tarini, M.D., MS, will make it her personal mission to ensure that more pediatric researchers get to know SPR and are so excited about the organization that they become active members. In May 2019 Dr. Tarini becomes Vice President of the society that aims to stitch together an international network of interdisciplinary researchers to improve kids’ health. Four-year SPR leadership terms begin with Vice President before transitioning to President-Elect, President and Past-President, each for one year.
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, associate director for Children’s Center for Translational Research.
“I’m delighted that Dr. Tarini was elected to this leadership position, and I am impressed by her vision of improving SPR’s outreach efforts,” says Mark Batshaw, M.D., Executive Vice President, Chief Academic Officer and Physician-in-Chief at Children’s National. “Her goal of engaging potential members in networking through a variety of ways – face-to-face as well as leveraging digital platforms like Twitter, Facebook and LinkedIn – and her focus on engaging junior faculty will help strengthen SPR membership in the near term and long term.”
Dr. Tarini adds: “Success to me would be leaving after four years with more faculty – especially junior faculty – approaching membership in SPR with the knowledge and enthusiasm that they bring to membership in other pediatric societies.”
SPR requires that its members not simply conduct research, but move the needle in their chosen discipline. In her research, Dr. Tarini has focused on ensuring that population-based newborn screening programs function efficiently and effectively with fewer hiccups at any place along the process.
Thanks to a heel stick to draw blood, an oxygen measurement, and a hearing test, U.S. babies are screened for select inherited health conditions, expediting treatment for infants and reducing the chances they’ll experience long-term health consequences.
“The complexity of this program that is able to test nearly all 4 million babies in the U.S. each year is nothing short of astounding. You have to know the child is born – anywhere in the state – and then between 24 and 48 hours of birth you have to do testing onsite, obtain a specific type of blood sample, send the blood sample to an off-site lab quickly, test the sample, find the child if the test is out of range, get the child evaluated and tested for the condition, then send them for treatment. Given the time pressures as well as the coordination of numerous people and organizations, the fact that this happens routinely is amazing. And like any complex process, there is always room for improvement,” she says.
Dr. Tarini’s research efforts have focused on those process improvements.
As just one example, the Advisory Committee on Heritable Disorders in Newborns and Children, a federal advisory committee on which she serves, was discussing how to eliminate delays in specimen processing to provide speedier results to families. One possible solution floated was to open labs all seven days, rather than just five days a week. Dr. Tarini advocated for partnering with health care engineers who could help model ways to make the specimen transport process more efficient, just like airlines and mail delivery services. A more efficient and effective solution was to match the specimen pick-up and delivery times more closely with the lab’s operational times – which maximizes lab resources and shortens wait times for parents.
Conceptual modeling comes so easily for her that she often leaps out of her seat mid-sentence, underscoring a point by jotting thoughts on a white board, doing it so often that her pens have run dry.
“It’s like a bus schedule: You want to find a bus that not only takes you to your destination but gets you there on time,” she says.
Dr. Tarini’s current observational study looks for opportunities to improve how parents in Minnesota and Iowa are given out-of-range newborn screening test results – especially false positives – and how that experience might shake their confidence in their child’s health as well as heighten their own stress level.
“After a false positive test result, are there parents who walk away from newborn screening with lingering stress about their child’s health? Can we predict who those parents might be and help them?” she asks.
Among the challenges is the newborn screening occurs so quickly after delivery that some emotionally and physically exhausted parents may not remember it was done. Then they get a call from the state with ominous results. Another challenge is standardizing communication approaches across dozens of birthing centers and hospitals.
“We know parents are concerned after receiving a false positive result, and some worry their infant remains vulnerable,” she says. “Can we change how we communicate – not just what we say, but how we say it – to alleviate those concerns?”
Children’s researcher Zhe Han, Ph.D., has received a $2 million award from the National Institutes of Health (NIH) to study new approaches to treat kidney disease linked to inheriting Apolipoprotein L1 (APOL1) risk alleles. These risk alleles are particularly common among persons of recent African descent, and African Americans are disproportionately affected by the increased risk in kidney disease associated with these risk alleles.
Han, an associate professor in Children’s Center for Genetic Medicine Research, has established a leading research program that uses the fruit fly Drosophila as a model system to study how genetic mutations lead to disease.
“Drosophila is a very basic model, but studies in the fly have led to major breakthroughs in understanding fundamental biological processes that underlie health and disease in humans,” Han says. “Since coming to Children’s National five years ago, I have focused a significant part of my research studying particular fly cells called nephrocytes that carry out many of the important roles of human kidney glomeruli, units within the kidney where blood is cleaned. Working together with clinician colleagues here, we have demonstrated that these Drosophila cells can be used to very efficiently study different types of renal disease caused by genetic mutations.”
The APOL1 risk alleles are genetic variants, termed G1 and G2, found almost exclusively in people of African ancestry and can lead to a four-fold higher risk of end-stage kidney disease, the last of five stages of chronic kidney disease. Exactly how inheriting these risk alleles increases the risk of kidney disease remains an unanswered question and the focus of considerable research activity. Han’s laboratory has developed a Drosophila model of APOL1-linked renal disease by producing the G1 and G2 forms of APOL1 specifically in nephrocytes. This led to defects in fly renal cells that strikingly overlap with disease-associated changes in experimental model and human kidney cells expressing APOL1 risk alleles.
The new NIH award will fund large-scale screening and functional testing to identify new treatment targets and new drugs to treat kidney disease linked to APOL1. Using a genetic screening approach, Han’s lab will identify nephrocyte “modifier” genes that interact with APOL1 proteins and counter the toxic effects of risk-associated G1 and G2 variants.
The team also will identify nephrocyte genes that are turned on or off in the presence of APOL1 risk alleles, and confirm that such “downstream” APOL1-regulated genes are similarly affected in experimental model and human kidney cells. The potential of the newly identified “modifier” and “downstream” genes to serve as targets of novel therapeutic interventions will be experimentally tested in fly nephrocytes in vivo and in cultured mammalian kidney cells.
Finally, the Drosophila model will be used as a drug screening platform for in vivo evaluation of positive “hits” from a cell-based APOL1 drug screening study in order to identify compounds that are most effective with the fewest side effects.
“These types of studies can be most efficiently performed in Drosophila,” Han adds. “They take advantage of the speed and low cost of the fly model system and the amazing array of well-established, sophisticated genetic tools available for the fly. Using this model to elucidate human disease mechanisms and to identify new effective therapies has truly become my research passion.”
