“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.”

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.

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.

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.

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.

Kristen Sgambat, Ph.D., R.D. and Asha Moudgil, M.D. receive Editors’ Choice Award

Kristen Sgambat, Ph.D., and Asha Moudgil, M.D.

Children’s National Hospital researchers Kristen Sgambat, Ph.D., and Asha Moudgil, M.D., were presented with the 2021 AJKD Editors’ Choice Award.

The American Journal of Kidney Disease (AJKD) announced the selection of the 2021 AJKD Editors’ Choice Award, recognizing outstanding articles published in their journal this year.

Children’s National Hospital researchers Kristen Sgambat, Ph.D., and Asha Moudgil, M.D., were presented with the 2021 AJKD Editors’ Choice Award for their July 2021 study, Social determinants of cardiovascular health in African American children with chronic kidney disease: An analysis of the chronic kidney disease in children (CKiD).

The study is the first to investigate the relationship between race, socioeconomic factors and cardiovascular health in children with chronic kidney disease. Dr. Sgambat, Dr. Moudgil and their collaborators found that African American children with chronic kidney disease had increased evidence of socioeconomic challenges, including food insecurity, reliance on public insurance, lower household incomes and lower levels of maternal education. These children had worse cardiovascular outcomes than Caucasian children with the same chronic kidney conditions. Notably, the cardiovascular outcomes of the two groups became more alike when statistical analysis was applied to equalize their socioeconomic factors. This suggests that these socioeconomic indicators do play a role in adverse cardiovascular health outcomes observed among African American children with chronic kidney disease.

“The findings of this study are important because they highlight the urgent need to shift the clinical research paradigm to investigate how social, rather than biological, factors contribute to racial differences in health outcomes,” said Dr. Sgambat. “Future studies should focus on the impact of systemic racism on cardiovascular health among children with chronic kidney disease, an area not well-studied so far.”

Looking back one year later – Keeping it Renal: Global Cuisine for Kids

plate of food

The cookbook introduces a variety of culturally diverse kidney-friendly recipes that kids of all ages love.

It has been one year since the Children’s National Hospital Department of Nephrology released their cookbook “Keeping it Renal: Global Cuisine for Kids” and we are still receiving requests for this collection of recipes. 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. “Children on dialysis have to give up a lot of what they like to eat. This cookbook introduces a variety of culturally diverse kidney-friendly recipes that kids of all ages love. By learning to cook these recipes, our patients can take an active role in their own healthcare and learn some fun new skills,” said Kristen Sgambat, Ph.D., R.D., and Asha Moudgil, M.D., medical director of transplant.

It is often challenging for children and their families to balance these dietary restrictions with proper nutrition and enjoyable mealtimes. “This cookbook offers novel and exciting recipes that patients and families may not be aware of. Seeing these options can help patients see that a renal diet does not have to be bland or repetitive and thus improve patients’ outlook on treatment and motivate them to adhere to the dietary restrictions,” said Kaushalendra Amatya, Ph.D., pediatric psychologist for Nephrology and Cardiology at Children’s National.

As an innovative way to facilitate adherence to these limitations, our nephrology department collaborated with our patient families to create the 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 7 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 dialysis and transplant patients, we are always looking for new ways to support our patient families.

Special issue of Pediatric Transplantation features Children’s National experts

Pediatric Transplantation Journal Cover

While much has been written about advances in the field of pediatric transplantation, there have been relatively few publications that address the social, psychological and day‐to‐day struggles faced by pediatric transplant recipients and their families. A special February 2021 issue of the journal Pediatric Transplantation, guest edited by Children’s National Hospital nephrologist and medical director of transplant Asha Moudgil, M.D., features a compilation of articles from a diverse group of professionals who share their expertise on topics related to healthy living for pediatric solid organ transplant patients. Among these leaders in their fields are several clinicians from Children’s National, including Jonathan Albert, M.D. (Infectious Diseases fellow), Benjamin Hanisch, M.D. (Transplant Infectious Diseases), Kristen Sgambat, Ph.D., R.D. (Renal Dietician), Melissa R. Meyers, M.D. (Nephrologist) and Kaushalendra Amatya, Ph.D. (Psychologist).

In an editorial co-written with Priya Verghese, M.D., of Ann & Robert H. Lurie Children’s Hospital of Chicago, Dr. Moudgil writes, “It is widely acknowledged by those practicing in the field of transplant medicine that taking care of pediatric transplant recipients is a complex endeavor for all parties involved, including patients, families, and providers. In this compendium, we bring you expertise from a diverse group of professionals — including physicians, psychologists, social workers, and nutritionists. These authors provide a concise summary of the literature and evidence when available, and offer personal insight where there is paucity of literature in topics related to healthy living in pediatric transplantation.”

Dr. Albert, Dr. Hanisch and Sgambat provide their expertise in an article titled “Approaches to safe living and diet after solid organ transplantation,” which reviews the risks that pediatric and adolescent solid organ transplant recipients encounter through exposures such as household contacts, outdoor activities, travel, animal exposures and dietary choices.

Like their peers, transplant recipients go through challenges of sexual development, but are at greater risk for sexually transmitted diseases due to their chronic immunosuppression. To address this need, Dr. Meyers and colleagues provide an introductory sexual preventive care resource for adolescent and young adult solid organ transplant recipients in their article “Promoting safe sexual practices and sexual health maintenance in pediatric and young adult solid organ transplant recipients.

And, in an article titled “Psychological functioning and psychosocial issues in pediatric kidney transplant recipients,” Dr. Amatya and colleagues analyze psychological and psychosocial factors related to medical outcomes and overall well‐being post‐transplant.

Social determinants of cardiovascular health in African American children with CKD

Asha Moudgil examines patient

In a recent study, Asha Moudgil, M.D., and colleagues looked at differences in socioeconomic factors and subclinical cardiovascular disease markers by race in chronic kidney disease patients.

Children with chronic kidney disease (CKD) are known to have an increased risk for cardiovascular (CV) disease. African American children with CKD are also disproportionately affected by socioeconomic disadvantages related to systemic racism.

In a recent analysis of 3,103 visits from 628 children enrolled in the Chronic Kidney Disease in Children (CKiD) study, Children’s National Hospital researchers Kristen Sgambat, Ph.D., and Asha Moudgil, M.D., and their colleagues found that African American children with CKD had increased left ventricular mass index, more ambulatory hypertension and differences in lipid profile compared with Caucasian children. After adjusting for socioeconomic factors (public health insurance, household income, maternal education, food insecurity, abnormal birth history), a trend towards attenuation of the differences in these CV markers was observed.

The authors of the study conclude that, “as many social determinants of health were not captured by our study, future research should examine effects of systemic racism on CV health in this population.”

Carnitine may improve heart function in children receiving CRRT

close up of an IV bag

A first-of-its-kind study demonstrated that IV carnitine supplementation is associated with improvement in myocardial strain and repletion of plasma total and free carnitine in children with AKI receiving CRRT.

Supplementation of a special nutrient could help improve heart function in children receiving continuous dialysis in critical care units. The nutrient carnitine plays an essential role in producing energy for use by heart and skeletal muscles. Critically ill children with acute kidney dysfunction often need a continuous dialysis therapy (also known as CRRT, continuous renal replacement therapy) to help remove toxins while kidneys are not working. An unintended consequence of this CRRT is removal of carnitine. Often these critically ill children are unable to eat by mouth and therefore can’t receive carnitine unless it is supplemented. Children’s National Hospital researchers have proven that intravenous carnitine supplementation is associated with repletion of the body’s carnitine supply and may cause improvement in heart function as shown by heart strain analysis (which detects subclinical cardiac dysfunction that may not be apparent by traditional echocardiography).

In a first-of-its-kind study, the Children’s National researchers, Asha Moudgil, M.D., Kristen Sgambat, M.D., and Sarah Clauss, M.D., investigated carnitine deficiency in children receiving CRRT. They demonstrated for the first time that these children become severely deficient in carnitine after being on CRRT for >1 week, and that carnitine supplementation is associated with carnitine repletion and improved heart function. This knowledge can help to guide clinical care, as carnitine can be easily added to the IV nutritional formulations that are typically given to these patients.

Although little was previously known about carnitine status in patients with acute kidney injury (AKI) receiving CRRT, iatrogenic carnitine deficiency related to chronic hemodialysis (HD) in patients with end stage renal disease is a well-known phenomenon. It was theorized that given the continuous removal of solutes by CRRT in combination with lack of dietary intake and impaired production of endogenous carnitine by the kidney in critically ill children with AKI, carnitine would be rapidly depleted.

The latest controlled pilot study (NCT01941823) of 48 children hypothesized that carnitine supplementation would improve left ventricular function in children receiving CRRT. Children ages 1-21 years with AKI requiring CRRT, who were admitted to the pediatric intensive care unit at Children’s National Hospital from 2015 to 2018 were eligible to prospectively enroll in the “CRRT Intervention group,” if they were total parenteral nutrition (TPN)-dependent and not receiving any enteral or IV carnitine prior to enrollment.

The researchers say that “An exciting collaborative effort between nephrology and cardiology made it possible to use a sophisticated technology known as speckle tracking imaging to study the effects of carnitine on heart in this population.” This technology can identify early changes in heart motion, also known as cardiac strain that may not be detected using standard heart imaging techniques.

This is the first study to demonstrate that IV carnitine supplementation is associated with improvement in myocardial strain and repletion of plasma total and free carnitine in children with AKI receiving CRRT. A cohort of pediatric chronic HD patients demonstrated similar benefits in a prior study conducted by Drs. Moudgil and Sgambat. Compared with chronic HD, carnitine is even more rapidly depleted by CRRT, with losses approximating 80% of intake. The effect of carnitine deficiency and supplementation on cardiovascular function in patients receiving CRRT had not been previously investigated.

The pilot study by Drs. Moudgil, Sgambat, and Clauss was single center and limited by small sample size. The small sample size may have limited the ability to detect significant differences in demographics and clinical characteristics and multivariable analyses could not be performed. However, given that it is a pilot study, the findings provide a solid launching point for future investigations to show how supplementation can be best utilized to optimize cardiac outcomes in children receiving CRRT.
