Update: Collaboration across borders to improve access to nephrology care

Marva Moxey-Mims, M.D., division chief of Nephrology at Children’s National, has a grant from the International Pediatric Nephrology Association (IPNA) to bring care to children with kidney disease in Jamaica.

During her recent trip, Dr. Moxey-Mims was joined by peritoneal dialysis nurse, Jennifer Carver, RN, and three pediatric nephrologists in Jamaica, Drs. Maolynne Miller, Nadia McClean and Sandrica Peart. Together, they trained close to 30 nurses from three hospitals across the island, including the Bustamante Children’s Hospital, the University Hospital of the West Indies — both in Kingston — and the Cornwall Regional Hospital in Montego Bay.

Nurses were given hands-on training in using peritoneal dialysis cycler machines and manual peritoneal dialysis. The training is part of an initiative that focuses on:

  • Improving clinical training of staff (medical, nursing, and allied health) involved in caring for children with kidney disease
  • Developing and upgrading services for children and adolescents with kidney diseases
  • Educating the community on disease awareness and prevention strategies

“Our ability to offer innovative training and resources to nurses underscores our commitment to ensuring children throughout Jamaica receive the essential care they require,” said Dr. Moxey-Mims. “This signifies to both domestic and international audiences that we’re upholding our pledge to health equity.”

Revolutionizing pediatric nephrology one patient at a time

Marva Moxey-Mims

“With each kidney transplant, we’re not just restoring the health of children, we’re pioneering progress and setting new benchmarks for the field of pediatric nephrology,” says Marva Moxey-Mims, M.D., chief of Nephrology at Children’s National Hospital.

“With each kidney transplant, we’re not just restoring the health of children, we’re pioneering progress and setting new benchmarks for the field of pediatric nephrology,” says Marva Moxey-Mims, M.D., chief of Nephrology at Children’s National Hospital. “We offer not just treatment, but a chance for our patients to flourish and live their best life.”

Big picture

The Kidney Transplantation Program at Children’s National is the only one of its kind in the Washington, D.C., region focused on the needs of children and teens with kidney disease.

Performing an average of 15-20 kidney transplants per year, the program’s latest one- and three-year graft and patient survival data from the Scientific Registry for Transplant Recipients is 100%.

“Our program surpasses national numbers, reflecting a commitment to exceptional care, superior patient outcomes and a focus on setting a new standard for excellence in transplant support,” says Dr. Moxey-Mims.

Children’s National leads the way

At the forefront of groundbreaking treatment, the nephrology team is pioneering progress by providing innovative care and resources. One example is the hospital’s collaboration with the National Kidney Registry and MedStar Georgetown Transplant Institute’s Living Donor Program. This provides a greater chance of finding more suitable donors for difficult-to-match children and has resulted in altruistic donations.

“Through living kidney donations, we redefine the timeline for pediatric transplants. Children experience shorter waits and swifter paths to renewed health compared to the national wait list,” says Asha Moudgil, M.D., medical director of the Kidney Transplantation Program at Children’s National. “It’s a testament to our commitment to making a difference in every child’s life.”

That commitment is also seen in the hospital’s focus on making sure families have the resources they need during their medical journey.

“Caring for a child with renal disease is an immense challenge, not only for the young patients but also for their families. The demanding schedule of hospital visits, often three times a week, adds an extra layer of stress and disruption to daily life,” says Dr. Moudgil.

Through grant funding from donors and national programs, families with children undergoing kidney transplants and dialysis can receive financial assistance. In some cases, families receive up to $2,000 of mortgage or rental payment assistance. Families can also receive funds for medication co-pays and other expenses incurred around the time of the transplant.

“In the face of medical adversity, these funds become a source of support,” says Dr. Moudgil. “We make sure every family, regardless of financial constraints, can access the care and resources their child needs.”

Bottom line

Children’s National is at the forefront of pediatric kidney transplantation. “Our unique approach ensures every facet of a patient’s journey is considered,” says Dr. Moxey-Mims. “We’ve created an environment where success is not just a medical outcome but a comprehensive and sustained improvement in a child’s overall quality of life.”

Modified aquapheresis for the smallest patients in intensive care

father touching newborn baby's head

To date, four patients have benefited from modified aquapheresis at Children’s National in both the PICU and the CICU.

The Division of Nephrology at Children’s National Hospital now offers modified aquapheresis for the smallest patients with acute kidney injury or chronic kidney disease in intensive care units. Aadil Kakajiwala, M.D., MSCI, director of Pediatric Acute Kidney Support Therapies, has been the leader in establishing modified aquapheresis at Children’s National. He joined the faculty at Children’s National in 2021 after completing his pediatric nephrology fellowship at the Children’s Hospital of Philadelphia and pediatric critical care medicine fellowship at Children’s National.

To date, four patients have benefited from modified aquapheresis at Children’s National in both the PICU and the CICU. Dialysis equipment designed for adults has filter set volumes as high as 165ml. Since implementing modified aquapheresis, the new equipment’s filter set volume is just 35ml, making it a great option for dialyzing small patients as low as 1.8kg. This limits blood exposure to the patient and overcomes the limitation of obtaining larger vascular access by using a PICC line.

Dr. Kakajiwala looks to continue training nephrologists, intensive care unit providers and staff across the hospital on modified aquapheresis. “This new offering allows us to offer dialysis to our smallest patients. By utilizing modified aquapheresis, we ensure simultaneous removal of waste products along with fluid removal during the therapy,” says Dr. Kakajiwala. He hopes to work on standardizing all forms of renal replacement therapy offered at Children’s National across all care providers.

Patient and doctor demoing Rare-CAP technology

M.D. in your pocket: New platform allows rare disease patients to carry medical advice everywhere

When someone has a rare disease, a trip to the emergency room can be a daunting experience: Patients and their caregivers must share the particulars of their illness or injury, with the added burden of downloading a non-specialist on the details of a rare diagnosis that may change treatment decisions.

Innovators at Children’s National Hospital and Vanderbilt University Medical Center, supported by Takeda, are trying to simplify that experience using a new web-based platform called the Rare Disease Clinical Activity Protocols, or Rare-CAP. This revolutionary collection of medical information allows patients to carry the latest research-based guidance about their rare disorders in their phones, providing a simple QR code that can open a trove of considerations for any medical provider to evaluate as they work through treatment options for someone with an underlying rare disease.

“No one should worry about what happens when they need medical help, especially patients with rare diseases,” said Debra Regier, M.D., division chief of Genetics and Metabolism at Children’s National and Rare-CAP’s lead medical advisor. “We built this new tool because I have watched as my patient-families have wound up in an emergency room — after all, kids get sprains or fractures — but they don’t have the expertise of a rare disease specialist with them. My hope is that they’re going to pull out their phones and access Rare-CAP, which will explain their rare disease to a new provider who can provide more thoughtful and meaningful care.”

The big picture

A rare disease is defined as any disorder that affects less than 200,000 people in the United States. Some 30 million Americans are believed to be living with one of the 7,000 known rare disorders tracked by the National Organization of Rare Diseases (NORD). Led by Dr. Regier, the Rare Disease Institute at Children’s National is one of 40 NORD centers for excellence in the country that provide care, guidance and leadership for the wide array of disorders that make up the rare disease community.

While a key goal of Rare-CAP is to bolster patient self-advocacy, the platform will also allow medical providers to proactively search for protocols on rare diseases when they know they need specialized advice from experts at Children’s National, a network of tertiary care centers and patient organizations.

As a leading values-based, R&D-driven biopharmaceutical company, Takeda has committed $3.85 million to the project to help activate meaningful change and empower a brighter future for rare disease communities, providing a unique understanding of the struggle that patients and caregivers face when they need care.

“Our team, alongside the medical and rare disease community, saw the need for a single portal to collect standardized care protocols, and we are thrilled to see this innovative tool come to life,” said Tom Koutsavlis, M.D., head of U.S. Medical Affairs at Takeda. “People with rare diseases and their caregivers need faster access to authoritative medical information that providers anywhere can act on, this will lead to improving the standard of care, accelerating time to diagnosis and breaking down barriers to increase equitable access.”

The patient benefit

The creators of Rare-CAP imagined its use in a wide range of settings, including emergency rooms, surgical suites, dental offices, urgent care offices and school clinics. The platform will eventually profile thousands of rare diseases and lay out the implications for care, while also creating a dynamic conversation among users who can offer updates based on real-world experience and changes in medical guidance.

“Our patients are unique, and so is this tool,” Dr. Regier said. “As we roll out Rare-CAP, we believe it is just the beginning of the conversation to expand the platform and see its power for the patient and provider grow, with each entry and each new rare disease that’s added to the conversation.”

Children’s National Hospital ranked #5 in the nation on U.S. News & World Report’s Best Children’s Hospitals Honor Roll

U.S. News BadgesChildren’s National Hospital in Washington, D.C., was ranked #5 in the nation on the U.S. News & World Report 2023-24 Best Children’s Hospitals annual rankings. This marks the seventh straight year Children’s National has made the Honor Roll list. The Honor Roll is a distinction awarded to only 10 children’s hospitals nationwide.

For the thirteenth straight year, Children’s National also ranked in all 10 specialty services, with eight specialties ranked in the top 10 nationally. In addition, the hospital was ranked best in the Mid-Atlantic for neonatology, cancer, neurology and neurosurgery.

“Even from a team that is now a fixture on the list of the very best children’s hospitals in the nation, these results are phenomenal,” said Kurt Newman, M.D., president and chief executive officer of Children’s National. “It takes a ton of dedication and sacrifice to provide the best care anywhere and I could not be prouder of the team. Their commitment to excellence is in their DNA and will continue long after I retire as CEO later this month.”

“Congratulations to the entire Children’s National team on these truly incredible results. They leave me further humbled by the opportunity to lead this exceptional organization and contribute to its continued success,” said Michelle Riley-Brown, MHA, FACHE, who becomes the new president and CEO of Children’s National on July 1. “I am deeply committed to fostering a culture of collaboration, empowering our talented teams and charting a bold path forward to provide best in class pediatric care. Our focus will always remain on the kids.”

“I am incredibly proud of Kurt and the entire team. These rankings help families know that when they come to Children’s National, they’re receiving the best care available in the country,” said Horacio Rozanski, chair of the board of directors of Children’s National. “I’m confident that the organization’s next leader, Michelle Riley-Brown, will continue to ensure Children’s National is always a destination for excellent care.”

The annual rankings are the most comprehensive source of quality-related information on U.S. pediatric hospitals and recognizes the nation’s top 50 pediatric hospitals based on a scoring system developed by U.S. News.

“For 17 years, U.S. News has provided information to help parents of sick children and their doctors find the best children’s hospital to treat their illness or condition,” said Ben Harder, chief of health analysis and managing editor at U.S. News. “Children’s hospitals that are on the Honor Roll transcend in providing exceptional specialized care.”

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.

The eight Children’s National specialty services that U.S. News ranked in the top 10 nationally are:

The other two specialties ranked among the top 50 were cardiology and heart surgery, and urology.

The future of Wilms tumor therapies: Q&A with Jeffrey Dome, M.D., Ph.D.

illustration of diseased kidneys

Dr. Dome’s mission is to come up with other therapies to treat Wilms tumor.

Conducting Wilms tumor research has placed Children’s National Hospital as the leader in this space. Jeffrey Dome, M.D., Ph.D., talks about the future of Wilms tumor therapies and what excites him about being able to offer different treatment options to this group of patients.

Q: What’s next for Wilms tumor therapy treatments?

A: Something we’ve learned is that we’re reaching the maximum benefit that we can achieve with conventional chemotherapy and have hit a plateau with some of the high-risk Wilms tumors.

If you look at the history of Wilms tumor, we’ve ratcheted up the cure rate by adding more and more chemotherapy agents. We’re now at a point in which patients can’t tolerate having more toxic chemotherapy added to their regimen. Our mission is to come up with other therapies that work differently.

Q: What have you learned that can lead to new therapy options?

A: I was a co-investigator on a National Cancer Institute-funded project called the TARGET study, which entailed sequencing several hundred Wilms tumors to identify genetic mutations that could be druggable. While a wealth of knowledge was gained on the nature of the biology of Wilms tumor, only a minority of Wilms tumors have targetable mutations. We understand what the mutations are, but most are not mutations that lend themselves to drug therapy.

Therefore, we must think about other forms of therapy for Wilms tumor, such as immunotherapy. That’s where the work with the T cells targeting the WT1 protein Wilms tumor cells come into play.

Q: What do the new therapies look like?

A: I think the future of Wilms tumor therapy will be combining the classic chemotherapy and radiation therapy that we’ve used for many years but also adding another component for the patients with the highest risk of relapse, such as immunotherapy.

Up until now, the studies that we’ve conducted using immunotherapy have introduced this treatment very late as a last resort after everything else has failed. We have seen early signals of efficacy and if we can corroborate this in current studies, I believe the future will be to introduce immunotherapy earlier in the treatment course.

There has been success using immunotherapy in other pediatric solid tumors such as neuroblastoma. I believe the prospects for Wilms tumor are also exciting.

Leading Wilms tumor research nationwide: Q&A with Jeffrey Dome, M.D., Ph.D.

histological image of Wilms Tumor

Children’s National has become a resource for patients and families with Wilms tumor.

During the past year, Children’s National Hospital saw nearly 100 patients with Wilms tumor and other less common kidney cancers of childhood, far more than most centers in the country. This is largely due to the reputation the hospital has established for specializing in these diseases. While most patients with Wilms tumor have excellent outcomes, a significant minority of children with kidney cancer do not fare well. Children’s National has become a resource for patients and families with these challenging cancers.

Behind this reputation is Jeffrey Dome, M.D., Ph.D., senior vice president of the Center for Cancer and Blood Disorders and division chief of Oncology at Children’s National, and the team of researchers he leads. For over a decade, he chaired the Children’s Oncology Group Renal Tumor Committee, an opportunity that gave him and his work great exposure.

Dr. Dome shares more on how Children’s National is leading in this space and what the future holds for new, exciting Wilms tumor treatment options.

Q: How is Children’s National leading in this space?

A: The good news is that for the most common type of childhood kidney cancer, Wilms tumor with “favorable histology,” the survival rate is more than 90%, which is an incredible success story. But approximately 25% of children and teens with other types of Wilms tumor and other kidney cancers do not fare as well. We specialize in kidney cancers that are harder to treat, such as anaplastic Wilms tumor, relapsed favorable histology Wilms tumor, bilateral Wilms tumor, clear cell sarcoma of the kidney, malignant rhabdoid tumor and renal cell carcinoma. Because we see a relatively large number of patients, we can draw on our prior experience and observations to recommend the best treatment options.

Q: What’s unique about this research?

A: We have several early-phase clinical trials that are of interest for children with relapsed kidney tumors. Some of these trials are part of research consortia, such as the National Cancer Institute-funded Pediatric Early Phase Clinical Trials Network (PEP-CTN). Other studies have been developed in-house at Children’s National, including a couple of studies using T cells to target pediatric solid tumors. The T cells that have been engineered by the Children’s National Cellular Therapy Laboratory are of particular interest for Wilms tumor because they target a protein called WT1, which is expressed in most Wilms tumors. In fact, WT1 was named after Wilms tumor. We have now had more than 25 patients with relapsed Wilms tumor come from around the country to participate in these studies. Based on early successes, we are continuing this line of research and trying to improve the technology in the current generation of studies.

Cardiovascular and bone diseases in chronic kidney disease

red and grey kidney illustration

A new study reviews cardiovascular and bone diseases in chronic kidney disease and end-stage kidney disease patients with a focus on pediatric issues and concerns.

In a study published by Advances in Chronic Kidney Disease and co-authored by Aadil Kakajiwala, M.D., MSCI, critical care specialist and nephrologist at Children’s National Hospital, a team reviewed cardiovascular and bone diseases in chronic kidney disease and end-stage kidney disease patients with a focus on pediatric issues and concerns.

Chronic kidney disease is common and causes significant morbidity including shortened lifespans and decrease in quality of life for patients. The major cause of mortality in chronic kidney disease is cardiovascular disease. Cardiovascular disease within the chronic kidney disease population is closely tied to disordered calcium and phosphorus metabolism. The metabolic bone disease of chronic kidney disease encompasses vascular calcification and the development of long-term cardiovascular disease.

Recent data suggest that aggressive management of metabolic bone disease can augment and improve cardiovascular disease status. Pediatric nephrologists need to manage the metabolic bone disease while keeping the ongoing linear growth and skeletal maturation in mind, which may be delayed in chronic kidney disease.

Profit facility status linked to longer wait times for kidney transplants

dialysis machines

Researchers found that profit dialysis facility status was associated with longer wait-listing times and kidney transplants.

Care of adults at profit versus nonprofit dialysis facilities has been associated with lower access to kidney transplants.

In a study published in JAMA, Celina Brunson, M.D., nephrologist and medical director of dialysis at Children’s National Hospital, and a cohort of researchers, found that profit facility status was associated with longer wait-listing times and kidney transplants. Whether there was a correlation in profit status was unknown before this study.

Researchers reviewed the United States (US) Renal Data System records of 13,333 pediatric patients under the age of 18 who started dialysis from the year 2000 through 2018 in U.S. dialysis facilities. This was followed up through June 30, 2019. Results showed that among U.S. pediatric patients undergoing dialysis, profit dialysis facility status was significantly associated with increased time to wait-listing and kidney transplants.

Emerging trends in pediatric chronic kidney disease and how to address them

kidney illustration

Chronic kidney disease (CKD) is a major public health problem associated with increased health costs, morbidity and mortality.

Chronic kidney disease (CKD) is a major public health problem associated with increased health costs, morbidity and mortality. CKD with rapid progression, which carries a poor prognosis, is more common in African American children. Thus, the development of a universal pediatric CKD screening program for high-risk children can be vital for social equity.

In a report published in the Journal of the National Medical Association, Marva Moxey-Mims, M.D., division chief of nephrology at Children’s National Hospital, and her co-authors, described trends in the incidence of pediatric CKD and management strategies aimed at enhancing health outcomes and reducing disease progression.

The authors also explored pediatric CKD trends and severity in different populations and CKD-related health problems. They discussed what to do about diagnosing early CKD in children and overall goals in managing CKD.

“This report can help push the field forward by providing information about options to those with chronic kidney disease, regardless of race, age or preexisting health conditions,” says Dr. Moxey-Mims.

Reproductive healthcare is key for adolescents with chronic kidney disease

doctor explaining menstrual cycle

In a report, Drs. Moxey-Mims and Brunson review the current state of reproductive healthcare for adolescents in the U.S., including those with chronic kidney disease.

In a report from the Journal of the American Society of Nephrology, Marva Moxey-Mims, M.D., division chief of nephrology at Children’s National Hospital and Celina Brunson, M.D., medical director of dialysis, review the current state of reproductive healthcare for adolescents in the United States. They also explore the limited information available for pregnancy in adolescents with chronic kidney disease, including concerns for the impact of pregnancy on progression of kidney disease, and the potential fetotoxic effects of medications prescribed for some types of kidney disease and in kidney transplantation. They describe barriers to access to important information for reproductive healthcare options, which may be exacerbated after the overturning of Roe v. Wade.

This work gives pediatric nephrologists information that can help them provide appropriate information and support to their adolescent patients with chronic kidney disease.

“This work will provide guidance around reproductive healthcare options for those with chronic kidney disease. We need to learn to be comfortable about ways to educate and help our teens with chronic kidney disease to optimize their overall health,” says Moxey-Mims.

Prevalence of mycophenolate mofetil discontinuation and subsequent outcomes in pediatric kidney transplant recipients: A PNRC study

Presenter: Asha Moudgil, M.D., medical director, Kidney Transplant

Mycophenolate mofetil (MMF) is a common maintenance immunosuppressant in children receiving kidney transplants but is often discontinued for various reasons. In this multi-center Pediatric Nephrology Research Consortium study, researchers sought to determine the prevalence and reasons for MMF discontinuation and its association with patient and allograft outcomes. They will be discussing their methodology and results from this study.

Additional Children’s National staff involved in the study include:

Changes in diastolic function and cardiac geometry after pediatric kidney transplantation: A longitudinal study

Presenter: Kristen Sgambat, Ph.D., clinical assistant professor

Children with end stage kidney disease are at high risk for cardiovascular morbidities. Indicators of systolic function, such as ejection fraction and fractional shortening, are often preserved and may not reveal cardiac dysfunction until it is severe. Longitudinal changes in diastolic function and cardiac geometry have not been well studied.

Additional Children’s National staff involved in the study include:

COVID19 in pediatric kidney transplant recipients: Incidence, outcomes, and response to vaccine

Presenter: Asha Moudgil, M.D., medical director, Kidney Transplant

At the start of the pandemic, no information was available on the outcomes of pediatric kidney transplant recipients with COVID-19. When the COVID-19 vaccine became available, response of immunosuppressed children to the vaccine was not known. While more information has become available in adult transplant recipients, information on pediatric transplant recipients remains limited.

The team will discuss their methodology of collecting information and their results and conclusions.

Additional Children’s National staff involved in the study include:

Poster presentation: Psychological functioning and adaptive behavior in pediatric patients awaiting renal transplantation.

Presenter: Kaushal Amatya, Ph.D., psychologist

Psychosocial functioning of children with chronic kidney disease (CKD) at pretransplant evaluation is associated with transplant readiness and post-transplant outcomes. Higher prevalence of emotional/behavioral issues is noted in children with CKD compared to healthy counterparts. Although issues with functional impairment is often reported, research on adaptive functioning using a validated measure is lacking. The study aimed to explore psychological and adaptive functioning in pediatric pre-transplant patients to identify areas in need of intervention.

Additional Children’s National staff involved in the study include:

  • Asha Moudgil, M.D., medical director, Kidney Transplant
  • Paige Johnson, Psychology resident

Tackling bias – the power of one

Marva Moxey MimsIn the most recent edition of the American Society of Pediatric Nephrology’s Kidney Notes, Children’s National Hospital Chief of Nephrology, Marva Moxey-Mims, M.D., wrote a perspective piece asking other providers to join her in an effort to see patients as a whole person and try to put aside personal biases, thereby improving overall patient care.

In this personal commentary, Dr. Moxey-Mims reflects on challenging herself to better serve patients by making sure they feel seen and to understand them. “Just think of the ripple effect if we can do this with even a fraction of our patients,” said Dr. Moxey-Mims. “The goodwill that patients will feel knowing that we are trying to see them is immeasurable.”
