Children’s National Hospital is proud to announce that it is participating in the Centers for Medicare & Medicaid Services (CMS) and Health Resources & Services Administration (HRSA)’s new End-Stage Renal Disease Treatment Choices Learning Collaborative (ETCLC). This effort will focus on addressing kidney disease prevention and treatment, including improved access to kidney transplants in the United States.

The ETCLC will engage transplant centers, Organ Procurement Organizations (OPOs), large donor hospitals, patients and donor family members to identify highly effective practices currently in use and spread the use of these practices throughout the organ procurement, kidney care and kidney transplant community to achieve the following three AIMs:

AIM #1: Increase the number of deceased donor kidneys transplanted
AIM #2: Decrease the current national discard rate of all procured kidneys
AIM #3: Increase the percentage of change for kidneys recovered for transplant in the 60-85 Kidney Donor Profile Index score group

The ETCLC brings the potential for collaboration, communication and innovation across geography into reality. By participating in the ETCLC, Children’s National will benefit by:

the creation of efficiencies and reduction of duplicative efforts in kidney patient care
exposure to new, innovative ideas regarding the kidney transplant process
the enhancement of communication and relationship building within the kidney care community
the application of substantive changes to improve the donation and transplantation system

Reducing urinary protein for patients with FSGS slows kidney decline

November 2, 2020

Reducing the amount of protein in the urine of patients with focal segmental glomerulosclerosis (FSGS), a rare disease in which scar tissue forms on the parts of the kidneys that filter waste from the blood, can significantly slow declines in kidney function and extend time before patients’ kidneys fail, a new analysis by a Children’s National Hospital researcher and her colleagues shows. These findings, published online Aug. 10, 2020, in the American Journal of Kidney Disease, could provide hope for patients who are able to lower their urinary protein with available treatments but aren’t able to achieve complete remission, the researchers say.

FSGS affects about seven per every million people in the general population. However, in the United States, it’s responsible for between 5 and 20% of all cases of end stage kidney disease (ESKD), a condition in which the kidney function declines enough that patients can’t survive without dialysis or a kidney transplant. There are no proven treatments specifically targeting FSGS, but steroids and other immunosuppressants have shown promise in clinical trials.

One characteristic sign of FSGS is proteinuria, in which too much protein is present in patients’ urine. Most clinical trials of FSGS treatments have focused on complete remission of proteinuria as a sign that the intervention is working. However, says Marva Moxey-Mims, M.D., researcher and chief of the Children’s National Division of Nephrology, only a fraction of patients meet that end goal. Instead, many patients achieve some reduction in proteinuria, but it’s been unclear whether those reductions lead to significant benefits for kidney health.

To investigate this question, Dr. Moxey-Mims and her colleagues used data from the National Institutes of Health-funded FSGS clinical trial that took place between November 2004 and May 2008. Participants in this study — 138 patients who developed proteinuria due to FSGS between the ages of 2 and 40 and didn’t respond to steroids — received one of two different immunosuppressant regimens. They received frequent checkups including urinary protein tests during the duration of the study and were followed for a maximum of 54 months.

Results showed that about 49% of the study participants’ proteinuria improved by 26 weeks of treatment on either regimen. More importantly, says Dr. Moxey-Mims, these patients retained significantly better kidney function over time, determined by a test called estimated glomerular filtration rate (eGFR), compared to those whose urinary protein remained high. The greater the reduction in proteinuria, the better their kidney function remained, and the longer their kidneys remained active before they developed ESKD.

“Even a modest reduction in proteinuria, as small as 20 or 30%, had an impact on these patients’ kidney health,” Dr. Moxey-Mims says.

Dr. Moxey-Mims notes that the finding could impact the design of clinical trials for FSGS treatments. Currently, these trials typically must include large numbers of patients to show a benefit if complete remission of proteinuria — which only occurred in about 20% of patients in the National Institute of Diabetes and Digestive and Kidney Diseases trial — is used as the end point.

If researchers use a range of proteinuria reduction as end points, she says, it could be easier to see if a drug or other intervention is working.

Similarly, she says, patients with FSGS and their doctors should view any proteinuria reduction as a positive.

“They shouldn’t be discouraged if they can’t reach full remission,” Dr. Moxey-Mims says. “Doctors and patients alike can feel reassured that if they’re reducing protein in the urine to some degree, then patients are getting some benefit.”

$6M gift powers new PKD clinical and research activities

November 14, 2019

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.

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.

Kidney disease outcomes differ between severely obese kids vs. adults after bariatric surgery

November 8, 2019

“We know that bariatric surgery improves markers of kidney health in severely obese adults and adolescents,” says Marva Moxey-Mims, M.D. “This research helps to elucidate possible differences in kidney disease outcomes between children and adults post-surgery.”

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.

Measuring quality of life after pediatric kidney transplant

May 10, 2019

“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.

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 10^th 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.

dnDSA and African American ethnicity linked with thickening of blood vessels after kidney transplant

May 8, 2019

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.

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.

African American stakeholders help to perfect the APOLLO study

March 18, 2019

Nichole Jefferson and Patrick O. 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.”

Preventing cardiovascular disease after pediatric kidney transplant

November 23, 2018

Pediatric nephrologist Asha Moudgil, M.D. examines a kidney transplant patient.

As obesity has continued to rise among children in the U.S., so has a condition called metabolic syndrome – a constellation of factors, including high abdominal fat, insulin resistance, high blood pressure, high triglycerides and low amounts of high-density lipoprotein (“good” cholesterol), that increase future risk of cardiovascular disease.

Although metabolic syndrome is dangerous in otherwise healthy children, it’s particularly so for those who’ve received kidney transplants due to chronic kidney disease, says pediatric nephrologist Asha Moudgil, M.D., medical director of transplant at Children’s National Health System. Dr. Moudgil and Children’s National co-authors, Registered Dietitian Kristen Sgambat, Ph.D., RD, and Cardiologist Sarah Clauss, M.D., published a literature review in the February 2018 Clinical Kidney Journal outlining recent research about the cardiovascular effects of metabolic syndrome after kidney transplantation.

“Simply having this transplant multiplies the risk of cardiovascular disease in this vulnerable population,” Dr. Moudgil says. “Combined with lifestyle factors that are driving up metabolic syndrome in general, it’s a ‘one-two punch’ for these patients.”

Dr. Moudgil explains that chronic kidney disease itself leads to poor growth, resulting in shorter stature that’s a risk factor for developing increased waist-to-height ratio upon becoming overweight. When children with this condition undergo long-awaited transplants, it reverses some factors that were suppressing appetite and keeping weight in check: The chronically high levels of urea in their blood decrease after transplant, improving their appetites; and there’s no need to maintain the restrictive diets they had been required to follow for kidney health prior to transplant.

The pharmaceutical regimen that patients follow post-transplant often includes steroids that independently contribute to weight gain and insulin resistance. Combined with the typical American high-fat, high-sugar, and high-sodium diet and low levels of physical activity, the majority of patients with chronic kidney disease gain significant weight after they receive transplants. The prevalence of obesity doubles the first year after transplantation, from about 15 percent to 30 percent, not only driving up cardiovascular disease risk but endangering the longevity of their transplant.

At the same time, says Sgambat, risk factors before and after transplantation drive up prevalence of other parts of metabolic syndrome. These include hypertension, which affects the majority of patients with chronic kidney disease before transplant and typically worsens due to sodium and water retention from immunosuppressive drugs. Dyslipidemia, or abnormal lipid concentrations in the blood, is also common among pediatric kidney transplant patients. One study included in the review showed that 71 percent of patients had high triglycerides three months post-transplant.

Ethnicity also can drive up risk for metabolic syndrome and cardiovascular disease. For example, the literature review says, individuals of African descent have a higher risk of these two conditions potentially due to genetic factors, such as high risk apolipoprotein L1 gene variants.

Together, these factors spur production of inflammatory molecules that trigger the development of early cardiovascular disease. Many kidney transplant recipients die from cardiovascular complications in early adulthood, Sgambat says, driving the need for early detection.

To that end, Dr. Moudgil says pediatric patients don’t typically show overt abnormalities in standard measures of cardiac functioning, such as echocardiography. As an alternative, she and colleagues cover three tools in the literature review that could offer advanced insight into whether patients have initial signs of cardiovascular disease. One of these is carotid intima-media thickness, a measure of the thickness of the carotid artery that can be obtained noninvasively by ultrasound. Another is myocardial strain imaging by speckle tracking echocardiography, a global measure of how the heart changes shape while beating. Cardiac magnetic resonance imaging (MRI), a relatively new technique, is already showing promise in detecting signs of early cardiovascular dysfunction.

A far simpler way to gauge cardiovascular risk, Sgambat adds, is calculating patients’ waist-to-height ratio. This measure doesn’t require sophisticated tools and can be tracked in any clinic over time, alerting patients to health-altering changes before it’s too late.

“It’s even more important to treat cardiovascular risk factors aggressively in this population,” Sgambat says. “Getting a concrete measure that something is trending in the wrong direction may motivate patients to change their diet or lifestyle in ways that a simple recommendation may not.”
