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

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

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

Plastic surgery and reconstructive care in Kenya and Nepal

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

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

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

Elevating epilepsy care in Ethiopia

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

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

New hope in Norway

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

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

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

Improving outcomes for babies in the Congo

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

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

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

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

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.”

Profit facility status linked to longer wait times for kidney transplants

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.

Carnitine may improve heart function in children receiving CRRT

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.

African American stakeholders help to perfect the APOLLO study

Nichole Jefferson and Patrick Gee

African Americans who either donated a kidney, received a kidney donation, are on dialysis awaiting a kidney transplant or have a close relative in one of those categories are helping to perfect a new study that aims to improve outcomes after kidney transplantation.

The study is called APOLLO, short for APOL1 Long-Term Kidney Transplantation Outcomes Network. Soon, the observational study will begin to enroll people who access transplant centers around the nation to genotype deceased and living African American kidney donors and transplant recipients to assess whether they carry a high-risk APOL1 gene variant.

The study’s Community Advisory Council – African American stakeholders who know the ins and outs of kidney donation, transplantation and dialysis because they’ve either given or  received an organ or are awaiting transplant – are opening the eyes of researchers about the unique views of patients and families.

Already, they’ve sensitized researchers that patients may not be at the same academic level as their clinicians, underscoring the importance of informed consent language that is understandable, approachable and respectful so people aren’t overwhelmed. They have encouraged the use of images and color to explain the apolipoprotein L1 (APOL1) gene. The APOL1 gene is found almost exclusively in people of recent African descent, however only 13 percent of these people carry the high-risk APOL1 variant that might cause kidney problems.

One issue arose early, during one of the group’s first monthly meetings, as they discussed when to tell patients and living donors about the APOLLO study. Someone suggested the day of the transplant.

“The Community Advisory Council told them that would not be appropriate. These conversations should occur well before the day of the transplant,” recalls Nichole Jefferson.

“The person is all ready to give a kidney. If you’re told the day of transplant ‘we’re going to include you in this study,’ that could possibly stop them from giving the organ,” Jefferson says. “We still remember the Tuskegee experiments. We still remember Henrietta Lacks. That is what we are trying to avoid.”

Patrick O. Gee, Ph.D., JLC, another Community Advisory Council member, adds that it’s important to consider “the mental state of the patient and the donor. As a patient, you know you are able to endure a five- to eight-hour surgery. The donor is the recipient’s hero. As the donor, you want to do what is right. But if you get this information; it’s going to cause doubt.”

Gee received his kidney transplant on April 21, 2017, and spent 33 days in the hospital undergoing four surgeries. His new kidney took 47 days to wake up, which he describes as a “very interesting journey.” Jefferson received her first transplant on June 12, 2008. Because that kidney is in failure, she is on the wait list for a new kidney.

“All I’ve ever known before APOLLO was diabetes and cardiovascular issues. Nobody had ever talked about genetics,” Gee adds. “When I tell people, I tread very light. I try to stay in my lane and not to come off as a researcher or a scientist. I just find out information and just share it with them.”

As he spoke during a church function, people began to search for information on their smart phones. He jotted down questions “above his pay grade” to refer to the study’s principal investigator. “When you start talking about genetics and a mutated gene, people really want to find out. That was probably one of the best things I liked about this committee: It allows you to learn, so you can pass it on.”

Jefferson’s encounters are more unstructured, informing people who she meets about her situation and kidney disease. When she traveled from her Des Moines, Iowa, home to Nebraska for a transplant evaluation, the nephrologist there was not aware of the APOL1 gene.

And during a meeting at the Mayo Clinic with a possible living donor, she asked if they would test for the APOL1 gene. “They stopped, looked at me and asked: ‘How do you know about that gene?’ Well, I’m a black woman with kidney failure.”

Patrick O. Gee received his kidney transplant on April 21, 2017, and spent 33 days in the hospital undergoing four surgeries. His new kidney took 47 days to wake up, which he describes as a “very interesting journey.”

About 100,000 U.S. children and adults await a kidney transplant. APOLLO study researchers believe that clarifying the role that the APOL1 gene plays in kidney-transplant failure could lead to fewer discarded kidneys, which could boost the number of available kidneys for patients awaiting transplant.

Gee advocates for other patients and families to volunteer to join the APOLLO Community Advisory Council. He’s still impressed that during the very first in-person gathering, all researchers were asked to leave the table. Only patients and families remained.

“They wanted to hear our voices. You rarely find that level of patient engagement. Normally, you sit there and listen to conversations that are over your head. They have definitely kept us engaged,” he says. “We have spoken the truth, and Dr. Kimmel is forever saying ‘who would want to listen to me about a genotype that doesn’t affect me? We want to hear your voice.’ ”

(Paul L. Kimmel, M.D., MACP, a program director at the National Institute of Diabetes and Digestive and Kidney Diseases, is one of the people overseeing the APOLLO study.)

Jefferson encourages other people personally impacted by kidney disease to participate in the APOLLO study.

“Something Dr. Kimmel always says is ‘You’re in the room.’ We’re in the room while it’s happening. It’s a line from Hamilton. That’s a good feeling,” she says. “I knew right off, these are not necessarily improvements I will see in my lifetime. I am OK with that. With kidney disease, we have not had advances in a long time. As long as my descendants don’t have to go through the same things I have gone through, I figure I have done my part. I have done my job.”
