Premier pediatric colorectal program opens doors at Children’s National

Marc Levitt

“With the broad range of expertise at Children’s National, including the nation’s best NICU, I’m confident that colorectal patients will get better, integrated care faster and more effectively here than anywhere else in the world,” says Marc Levitt, M.D.

World-renowned surgeon opens first program for care and treatment of colorectal conditions in the mid-Atlantic.

A new, highly-specialized surgical program at Children’s National Hospital is expected to draw patients from around the world. The colorectal surgery program is the first in the mid-Atlantic region to fully integrate surgery, urology, gynecology and gastroenterology into one cohesive program for children. The program is led by Marc Levitt, M.D., an internationally recognized expert in the surgical care and treatment of pediatric colorectal disorders who has performed over 10,000 surgeries to address a wide spectrum of problems involving the colon and rectum – more than any other full time practicing pediatric surgeon in the world.

“In the 25 years that I’ve been passionate about helping children with colorectal and pelvic conditions, I’ve learned that collaborative and integrated programs are the best way to care for them,” says Dr. Levitt. “With the broad range of expertise at Children’s National, including the nation’s best NICU, I’m confident that colorectal patients will get better, integrated care faster and more effectively here than anywhere else in the world.”

The program provides diagnosis and treatment for every type of colorectal disorder occurring in infants, children and adolescents, from the most common to the most complex. Every necessary specialty is integrated into the program in one convenient location to provide seamless care for all colon and rectum conditions, with particular expertise in:

  • Anorectal malformations
  • Cloacal malformations
  • Chronic constipation and fecal incontinence
  • Fecal and urinary incontinence related to spinal conditions such as spina bifida
  • Hirschsprung disease
  • Motility disorders

“Every child receives a customized treatment plan to address his or her unique needs,” Dr. Levitt says about the program. “Additionally, our surgeons often combine complex procedures across specialties to reduce the number of surgeries a child requires. It isn’t unusual for us to include urology, gynecology, and gastroenterology teams in the operating room alongside the colorectal surgeons so multiple issues can be addressed in a single procedure – we know that when possible, fewer surgeries is always better for the child.”

Dr. Levitt has cared for children from 50 states and 76 countries. He is the founder of Colorectal Team Overseas (CTO), a group of international providers who travel to the developing world to provide care for patients and teaching of their physicians and nurses. He co-founded the Pediatric Colorectal and Pelvic Learning Consortium (PCPLC), an organization of collaborating colorectal centers across the globe.

“We’re absolutely thrilled to welcome Marc Levitt and launch the comprehensive colorectal program under his expert leadership,” adds Anthony Sandler, M.D., surgeon-in-chief and vice president of the Joseph E. Robert, Jr., Center for Surgical Care at Children’s National. “There are few in the world who can provide the expertise and leadership in colorectal diagnoses and treatment that Marc brings with him to Children’s. Many children and families from the region and from around the world will benefit from his expertise and from the program in general.”

Stat Madness 2019

Vote for Children’s National in STAT Madness

Stat Madness 2019

Children’s National Health System has been selected to compete in STAT Madness for the second consecutive year. Our entry for the bracket-style competition is “Sensitive liquid biopsy platform to detect tumor-released mutated DNA using patient blood and CSF,” a new technique that will allow kids to get better treatment for an aggressive type of pediatric brain tumor.

In 2018, Children’s first-ever STAT Madness entry advanced through five brackets in the national competition and, in the championship round, finished second. That innovation, which enables more timely diagnoses of rare diseases and common genetic disorders, helping to improve kids’ health outcomes around the world, also was among four “Editor’s Pick” finalists, entries that spanned a diverse range of scientific disciplines.

“Children’s National researchers collaboratively work across divisions and departments to ensure that innovations discovered in our laboratories reach clinicians in order to improve patient care,” says Mark Batshaw, M.D., Children’s Executive Vice President, Chief Academic Officer and Physician-in-Chief. “It’s gratifying that Children’s multidisciplinary approach to improving the lives of children with brain tumors has been included in this year’s STAT Madness competition.”

Pediatric brain cancers are the leading cause of cancer-related death in children younger than 14. Children with tumors in their midline brain structures have the worst outcomes, and kids diagnosed with diffuse midline gliomas, including diffuse intrinsic pontine glioma, have a median survival of just 12 months.

“We heard from our clinician colleagues that many kids were coming in and their magnetic resonance imaging (MRI) suggested a particular type of tumor. But it was always problematic to identify the tumor’s molecular subtype,” says Javad Nazarian, Ph.D., MSC, a principal investigator in Children’s Center for Genetic Medicine Research. “Our colleagues wanted a more accurate measure than MRI to find the molecular subtype. That raised the question of whether we could actually look at their blood to determine the tumor subtype.”

Children’s liquid biopsy, which remains at the research phase, starts with a simple blood draw using the same type of needle as is used when people donate blood. When patients with brain tumors provide blood for other laboratory testing, a portion of it is used for the DNA detective work. Just as a criminal leaves behind fingerprints, tumors shed telltale clues in the blood. The Children’s team searches for the histone 3.3K27M (H3K27M), a mutation associated with worse clinical outcomes.

“With liquid biopsy, we were able to detect a few copies of tumor DNA that were hiding behind a million copies of healthy DNA,” Nazarian says. “The blood draw and liquid biopsy complement the MRI. The MRI gives the brain tumor’s ZIP code. Liquid biopsy gives you the demographics within that ZIP code.”

Working with collaborators around the nation, Children’s National continues to refine the technology to improve its accuracy. The multi-institutional team published findings online Oct. 15, 2018, in Clinical Cancer Research.

Even though this research technique is in its infancy, the rapid, cheap and sensitive technology already is being used by people around the globe.

“People around the world are sending blood to us, looking for this particular mutation, H3K27M, ” says Lindsay B. Kilburn, M.D., a Children’s neuro–oncologist, principal investigator at Children’s National for the Pacific Pediatric Neuro-Oncology Consortium, and study co-author. “In many countries or centers, children do not have access to teams experienced in taking a biopsy of tumors in the brainstem, they can perform a simple blood draw and have that blood processed and analyzed by us. In only a few days, we can provide important molecular information on the tumor subtype previously only available to patients that had undergone a tumor biopsy.”

“With that DNA finding, physicians can make more educated therapeutic decisions, including prescribing medications that could not have been given previously,” Nazarian adds.

The STAT Madness round of 64 brackets opened March 4, 2019, and the championship round voting concludes April 5 at 5 p.m. (EST).

In addition to Nazarian and Dr. Kilburn, study co-authors include Eshini Panditharatna, Madhuri Kambhampati, Heather Gordish-Dressman, Ph.D., Suresh N. Magge, M.D., John S. Myseros, M.D., Eugene I.

Food allergies: a research update

Assorted foods

Promising new therapies for food allergies are on the horizon, including an experimental immunotherapy awaiting federal approval that enables people who are very allergic to eat peanut protein without suffering serious side effects.

Good news, right?

As it turns out, the idea of a child who is highly allergic to a specific food eating that same food item makes kids with lifelong food allergies and their parents a bit queasy.

“It’s a very big paradigm shift. From diagnosis, children are told to avoid their food triggers at all cost. But now they may be counseled to approach the very thing that scares them, put it in their body and see what happens,” says Linda Herbert, Ph.D., an assistant professor in Children’s Division of Psychology and Behavioral Health.

“On the flip side, these new protections could reduce long-term anxieties, replacing daily anxiety about accidental exposure with a newfound sense of empowerment. Either way, a lot of families will need support as they try these new treatments that enable them to ingest a food allergen daily or wear a patch that administers a controlled dose of that food allergen,” Herbert says.

She will discuss food allergy treatments in the pipeline and families’ psychosocial concerns related to daily life as she presents a research update during the American Academy of Allergy, Asthma & Immunology (AAAAI) 2019 Annual Meeting. A select group, including Herbert, has been recognized with an AAAAI Foundation Heritage Lectureship, which honors distinguished AAAAI members with a special lecture and plaque.

Herbert’s symposium targets allied health professionals at the annual meeting, including psychologists, dietitians and nurse practitioners who attend to a host of psychosocial concerns felt by families affected by allergies to foods like eggs, nuts and cow’s milk.

“When patients arrive for outpatient therapy, they feel anxious about being safe when they’re out in public. They have anxieties about their children feeling safe at school as well as managing restaurant meals. They explain difficulties being included in social events like birthday parties, field trips and shared vacations,” Herbert says. “Some families restrict social activities due to stress and anxiety.”

Children’s National Health System takes a multidisciplinary approach for complex conditions like food allergies, she says, combining the expertise of psychologists, medical providers, research nurses, clinical nurses, registered dietitians and other allied health professionals.

“When we all communicate, we can see the complete picture. It strengthens the care that the child receives, and it’s especially powerful that it can happen all at once – rather than going to multiple appointments,” she adds.

During such group huddles, the team agrees on a plan together that is communicated to the family. One ongoing challenge is that one-third of school children with food allergies are bullied or teased.

“A lot of parents don’t necessarily know to ask or how to ask. I frequently suggest that clinicians discuss peer concerns more in clinic.”

Preemie Baby

Getting micro-preemie growth trends on track

Preemie Baby

According to Children’s research presented during the Institute for Healthcare Improvement 2018 Scientific Symposium, standardizing feeding practices – including the timing for fortifying breast milk and formula with essential elements like zinc and protein – improves growth trends for the tiniest preterm infants.

About 1 in 10 infants is born before 37 weeks gestation. These premature babies have a variety of increased health risks, including deadly infections and poor lung function.

Emerging research suggests that getting their length and weight back on track could help. According to Children’s research presented during the Institute for Healthcare Improvement 2018 Scientific Symposium, standardizing feeding practices – including the timing for fortifying breast milk and formula with essential elements like zinc and protein – improves growth trends for the tiniest preterm infants.

The quality-improvement project at Children’s National Health System targeted very low birth weight infants, who weigh less than 3.3 pounds (1,500 grams) at birth. These fragile infants are born well before their internal organs, lungs, brain or their digestive systems have fully developed and are at high risk for ongoing nutritional challenges, health conditions like necrotizing enterocolitis (NEC) and overall poor development.

The research team measured progress by tracking the micro-preemies’ mean delta weight Z-score for weight gain, which measures nutritional status.

“In this cohort, mean delta weight Z-scores improved by 43 percent, rising from -1.8 to the goal of -1.0, when we employed an array of interventions. We saw the greatest improvement, 64 percent, among preterm infants who had been born between 26 to 28 weeks gestation,” says Michelande Ridoré, MS, Children’s NICU quality-improvement program lead who presented the group’s preliminary findings. “It’s very encouraging to see improved growth trends just six months after introducing these targeted interventions and to maintain these improvements for 16 months.”

Within Children’s neonatal intensive care unit (NICU), micro-preemies live in an environment that mimics the womb, with dimmed lighting and warmed incubators covered by blankets to muffle extraneous noise. The multidisciplinary team relied on a number of interventions to improve micro-preemies’ long-term nutritional outcomes, including:

  • Reducing variations in how individual NICU health care providers approach feeding practices
  • Fortifying breast milk (and formula when breast milk was not available), which helps these extra lean newborns add muscle and strengthen bones
  • Early initiation of nutrition that passes through the intestine (enteral feeds)
  • Re-educating all members of the infants’ care teams about the importance of standardized feeding and
  • Providing a decision aid about feeding intolerance.

Dietitians were included in the daily rounds, during which the multidisciplinary team discusses each infant’s care plan at their room, and used traffic light colors to describe how micro-preemies were progressing with their nutritional goals. It’s common for these newborns to lose weight in the first few days of life.

  • Infants in the “green” zone had regained their birth weight by day 14 of life and possible interventions included adjusting how many calories and protein they consumed daily to reflect their new weight.
  • Infants in the “yellow” zone between day 15 to 18 of life remained lighter than what they weighed at birth and were trending toward lower delta Z-scores. In addition to assessing the infant’s risk factors, the team could increase calories consumed per day and add fortification, among other possible interventions.
  • Infants in the “red” zone remained below their birth weight after day 19 of life and recorded depressed delta Z-scores. These infants saw the most intensive interventions, which could include conversations with the neonatologist and R.N. to discuss strategies to reverse the infant’s failure to grow.

Future research will explore how the nutritional interventions impact newborns with NEC, a condition characterized by death of tissue in the intestine. These infants face significant challenges gaining length and weight.
