A new study published in the Journal of Diabetes, found that although nearly 80% of youth with Type 1 diabetes and COVID-19 infection are managed at home, youth from racial and ethnic minority groups – those with higher hemoglobin A1c values – and those with public insurance are at increased risk for hospitalization.

In a new study published in the Journal of Diabetes, researchers found that although nearly 80% of youth with Type 1 diabetes (T1D) and COVID-19 infection are managed at home, youth from racial and ethnic minority groups – those with higher hemoglobin A1c values – and those with public insurance are at increased risk for hospitalization. Most hospitalizations among these youth were related to diabetic ketoacidosis (DKA) (72%) and 86% of youth hospitalized had an A1c value over 9%. The increased risk for DKA among racial and ethnic minority groups and publicly insured youth in this study is indicative of disparities in T1D outcomes and aligns with other research findings both before and during the pandemic.

Adults with certain underlying medical conditions, like diabetes, are at an increased risk for severe illness from COVID-19. Though there are limited data on youth with T1D who have been infected with COVID-19, viral infections can make it harder to control blood glucose levels. If not properly managed, infections may lead to DKA, a serious life-threatening condition where the body converts fat instead of sugar into energy, causing ketones to build up in the blood and acid levels to rise.

“There is still more to learn about COVID-19 and how it affects children with diabetes and other underlying medical conditions,” said Brynn Marks, M.D., MS-HPEd, pediatric endocrinologist at Children’s National Hospital and one of the study’s co-authors. “We are hopeful that this latest data will emphasize the importance of optimizing glycemic control and give physicians and families more information about the virus and T1D so that severe illness and hospitalizations can possibly be prevented.”

In April 2020, the T1D Exchange Quality Improvement Collaborative, along with endocrinology clinics across the U.S., formed a COVID-19 clinical registry to better understand symptoms and outcomes of patients with T1D who also tested positive for SARS-CoV-2 infection. More than 46 centers nationwide, including Children’s National Hospital, submitted data to this novel registry of 266 youth under the age of 19 with previously established T1D and laboratory confirmed COVID-19.

The study found that nearly 80% of youth with T1D and known COVID-19 infection were cared for at home without any adverse outcomes. It is also important to note that COVID-19 was incidentally discovered in 16% of hospitalized youth admitted for reasons unrelated to COVID-19 or T1D (e.g. urological procedures, psychiatric admissions). However, the data revealed a disproportionate rate of hospitalizations and DKA among racial and ethnic minority groups, children who were publicly insured and those with higher A1c. Out of the 266 patients, 72% of the 61 patients were hospitalized due to DKA. An overwhelming majority (82%) of hospitalized patients had an A1c value greater than 9%. More than 40% of non-Hispanic Black youth in the study were hospitalized as compared to 14% of non-Hispanic white youth. Researchers also noted that those patients with public insurance were less likely to use insulin pumps and continuous glucose monitors, emphasizing the continued need to improve more access to diabetes technologies.

“Diabetes technology has advanced rapidly in the last decade and access to insulin pumps and continuous glucose monitors is improving, however these technological advances are perpetuating pre-existing disparities in T1D care and outcomes,” Dr. Marks said. “The data is clear and there is a pressing need to act to promote optimal care for all people with T1D.”

Recently, Dr. Marks and the Children’s National Diabetes team became official members of the Type 1 Diabetes Exchange Collaborative. The team looks forward to using the opportunity to improve diabetes care both here at Children’s National and across the country.

Raising awareness about Turner Syndrome

Gracie Popielarcheck

Gracie Popielarcheck was diagnosed at age one with Turner Syndrome.

By Roopa Kanakatti Shankar, M.D., M.S., Director of the Turner Syndrome Program at Children’s National Hospital.

The Children’s National  Turner Syndrome Clinic is part of the Division of Endocrinology and Diabetes which is ranked by U.S. News & World Report as one of the top 10 programs in the nation. The clinic opened in January 2019 and is the first of its kind in the Washington, D.C., region. A multidisciplinary clinic is held once a month with a team experts in cardiology, endocrinology, psychology, gynecology and genetics to help care for the needs of patients with Turner Syndrome all in one day. The referral network of specialties includes neuropsychology, otolaryngology, audiology, orthopedics, urology and dentistry.

Turner syndrome (TS) is a rare disease affecting girls, with a prevalence of around 25-50 out of every 100,000 females. It is caused by partial or complete loss of the second sex chromosome. This affects multiple organs and can cause heart defects, skeletal abnormalities, hearing loss and learning difficulties. It also affects growth and puberty and can cause infertility. Although the condition was first described in 1938 by Henry Turner, an endocrinologist from Oklahoma, and is well characterized, there is a significant delay in diagnosis and recognition of the condition, especially in milder forms that can still significantly impact the well-being of the individual.

Gracie Popielarcheck with a pet bird

“Having a Turner Syndrome clinic near our city has made life so much easier,” says Gracie’s mom, Leslie Popielarcheck. “We can see all of Gracie’s specialists all in one day and under one roof.”

Families often ask why it took so long to recognize this condition. Many findings can be subtle, the presentation can vary greatly and often short stature may be overlooked in some girls. We now recognize that the classic form (monosomy X) impacts less than half of the girls and the rest have mosaicism (45,X/ 46XX) or other structural abnormalities in the X-chromosome. Recognizing features beyond the classic “short stature, neck webbing, lymphedema and cardiac defects” is indeed important to get timely care for these girls and women across the lifespan. Many have recurrent ear infections and hearing loss. Most have a normal intelligence, and even superior verbal skills but face challenges in visual spatial perception, executive function, working memory and social cognition that impact academic achievement.

13-year-old Gracie Popielarcheck was diagnosed with TS at the age of one after her parents noticed a delay in her speech and development. “We had never heard of Turner Syndrome when Gracie was diagnosed,” says Leslie Popielarcheck, Gracie’s mom. “Gracie didn’t have the classic physical features that girls with Turner Syndrome are known to have.”

With support, most of these girls and women can manage the medical and psychosocial challenges and rise to their full potential. Advances in the field and multidisciplinary care models have helped in the establishment of TS clinics across the country that strive to improve the standard care for these girls.

However, several challenges remain:

  • Improving awareness among primary care physicians in regard to the extended spectrum and variability of presentation at a wide variety of ages
  • Decreasing health disparities and making multidisciplinary clinics and comprehensive care available and accessible even to disadvantaged communities
  • Ensuring adequate medical and social support for transition of young adults and care of adults with Turner syndrome

Kyra Dorfman, Dr. Shankar and Gracie.

Our TS program, initiated 2 years ago, aims to overcome these challenges and provide care to families impacted by TS in our community. We strive to serve as a Regional Resource for the community as well as physicians in our community and have been recognized by the TSGA (Turner syndrome Global Alliance) as one of only nine clinics nationwide with a Level 4 designation.

“Having a Turner Syndrome clinic near our city has made life so much easier,” Popielarcheck says. “We can see all of Gracie’s specialists all in one day and under one roof.”

As we highlight these resources for the Turner Syndrome Awareness Month this February 2021, and celebrate the strength and tenacity of our beautiful girls, we hope our efforts will improve recognition of the condition and delivery of comprehensive medical care and support to the community we serve.

There’s still more to learn about COVID-19 and diabetes

boy checking his blood glucose

Researchers have learned a lot about COVID-19 over the past year and are continuing to learn and study more about this infection caused by the SARS-CoV-2 virus. There have been many questions about whether COVID-19 affects people with diabetes differently than those without and why this might occur.

Diabetes experts, like Brynn Marks, M.D., M.S.H.P.Ed., endocrinologist at Children’s National Hospital, have been studying the relationship between COVID-19 and diabetes, especially in the pediatric population. Dr. Marks tells us more about what we know so far and further research that needs to be done when it comes to COVID-19 and diabetes.

1.      What do we know about COVID-19 and its effect on people with known diabetes?

The Centers for Disease Control and Prevention (CDC) currently lists type 2 diabetes (T2D) as a high risk condition for severe illness related to COVID-19 infection, while stating that adults with type 1 diabetes (T1D) might be at increased risk. A recent study from Vanderbilt University found that people with T1D and T2D were at approximately equal risk for complications of COVID-19 infection. As compared to adults without diabetes, adults with T1D and T2D were 3-4 times more likely to be hospitalized and to have greater illness severity. Given these comparable risks, both the American Diabetes Association and the Juvenile Diabetes Research Foundation are lobbying for adults with T1D to be given the same level or priority for COVID-19 vaccines as adults with T2D.

However, as pediatricians, we all know to be wary of extrapolating adult data to pediatrics. Children are less likely to be infected with COVID-19 and if they are, the clinical course is typically mild. To date, there have not been any studies of the impact of COVID-19 on youth with known T2D. Our clinical experience at Children’s National Hospital and reports from international multicenter studies indicate that youth with T1D are not at increased risk for hospitalization from COVID-19 infection. However, paralleling ongoing disparities in T1D care, African Americans with known T1D and COVID-19 infection were more likely to be develop diabetic ketoacidosis (DKA) than their White counterparts.

With the increased use of diabetes technologies, including continuous glucose monitors, insulin pumps and automated insulin delivery systems, diabetes care lends itself well to telemedicine. Studies from Italy during the period of lockdown showed better glycemic control among youth with T1D. Further studies are needed to better understand the implications of telehealth on diabetes care, particularly among those in rural areas with limited access to care.

Brynn Marks

Diabetes experts, like Brynn Marks, M.D., M.S.H.P.Ed., endocrinologist at Children’s National Hospital, have been studying the relationship between COVID-19 and diabetes, especially in the pediatric population.

2.      What do we know about the impact of the COVID-19 pandemic on children with newly diagnosed diabetes?

Nationwide studies from Italy and Germany over the first few months of the pandemic found no increase in the incidence of pediatric T1D during the COVID-19 pandemic as compared to the year before; in fact, the Italian study found that fewer children were diagnosed with T1D during the pandemic. However, many centers are seeing higher rates of DKA and more severe DKA at diagnosis during the pandemic, possibly due to decreased primary care visits and/or fears of contracting COVID-19 while seeking care.

To date, no studies have been published exploring the incidence of T2D in youth. A group from Children’s National, including myself, Myrto Flokas, M.D., Abby Meyers, M.D., and Elizabeth Estrada, M.D., from the Division of Endocrinology and Randi Streisand, Ph.D., C.D.C.E.S. and Maureen Monaghan, Ph.D., C.D.C.E.S., from the Department of Psychology and Behavioral Health, are gathering data to compare the incidence of T1D and T2D during the pandemic as compared to the year before.

3.      Can COVID-19 cause diabetes to develop?

This has been area of great interest, but the jury is still out. The SARS-CoV-2 virus, which causes COVID-19 infection, binds the angiotensin-converting enzyme 2 (ACE2) receptor which is located in many tissues throughout the body, including the pancreas. SARS-CoV-2 has been shown to infect pancreatic tissue leading to impaired glucose stimulated insulin secretion. Although the SARS-CoV-2 virus could plausibly cause diabetes, assessment has been complicated by many confounders that could be contributing to hyperglycemia in addition to or rather than the virus itself. Stress-induced hyperglycemia from acute illness, the use of high dose steroids to treat COVID-19 infection, and the disproportionate rates of infection among those already at high risk for T2D, as well as weight gain due to changes in day-to-day life as a result of social distancing precautions are all likely contributing factors.

New grant to assess screening tools for cystic fibrosis-related diabetes

woman writing data to medical form and glucometer for checking sugar level

A grant from the Cystic Fibrosis Foundation will help Children’s National researchers assess the feasibility and accuracy of two new cystic fibrosis-related diabetes screening tools.

Cystic fibrosis-related diabetes (CFRD) is the most common non-pulmonary manifestation of cystic fibrosis (CF), affecting up to 30% of adolescents and 50% of adults living with CF, according to the Cystic Fibrosis Foundation (CFF). CFRD is often asymptomatic and so the CFF recommends that people living with CF be screened for CFRD annually starting at 10 years of age using an oral glucose tolerance test.

Although early detection and treatment of CFRD can lead to significant clinical improvements and prolong life, rates of screening are poor, likely due to the burdensome nature of oral glucose tolerance testing (OGTT). Rates of OGTT screening in patients 10-17 years of age vary widely among CF care centers, ranging 5.9% to 100% with a median of 61.3% of patients at a given center completing screening. At Children’s National, only 46.4% of pediatric CF patients without CFRD completed the OGTT in 2019.  The most commonly cited reason for failure to complete recommended OGTT screening is the additional burden that this time-consuming fasting test, requiring three blood draws, places upon patients who already contend with multiple medical interventions.

“People living with CF face tremendous medical burdens.,” says Brynn Marks, M.D., MSHPEd, pediatric endocrinologist at Children’s National Hospital. “Novel, more convenient approaches to CFRD screening that can provide both diagnostic and therapeutic information are urgently needed.”

Dr. Marks and Carol Chace, MSW, a social worker at Children’s National, have collaborated to receive a $160,000 Pilot and Feasibility Award from the CFF that will allow researchers to assess the feasibility and accuracy of two new CFRD screening tools, the Dexcom G6 Pro, a continuous glucose monitoring (CGM), and the Digostics GTT@home, a home-based OGTT kit. The Dexcom G6 Pro is the first unblinded professional CGM that enables patients to see their glucose values and trends in real-time. The GTT@home uses a built-in timer and audio-visual cues to guide users to collect capillary blood samples through finger sticks.

“While the idea of home-based testing is exciting in general, it is particularly important in the midst of the COVID-19 pandemic, as many are limiting preventative health care visits,” says Dr. Marks. “This research will hopefully inform future larger studies that could one day allow for this screening to be done at home.”

iLet-Bionic-Pancreas

Children’s National to test bionic pancreas

iLet-Bionic-Pancreas

The iLet bionic pancreas helps patients manage their diabetes by both monitoring blood glucose levels and administering insulin and glucagon.

The final results of this clinical trial were published on September 29, 2022 in the New England Journal of Medicine.

Children’s National Hospital has been selected to participate in a multi-center clinical trial to test the efficacy of the iLet bionic pancreas — a device that automatically regulates blood sugar levels in patients with Type 1 diabetes.

Patients generally manage diabetes by constantly monitoring their blood sugar levels and administering insulin when necessary. Unfortunately, too much insulin can cause hypoglycemia, or low blood sugar, which can result in hypoglycemic seizures, coma or rarely, death. Thus, it is extremely important for people with diabetes to regulate their insulin dosages and maintain their blood sugar levels within a range decided by the family and diabetes team.

“The burden of caring for diabetes on a daily basis is grueling,” says Seema Meighan, FNP, a nurse practitioner involved in the upcoming clinical trial. “It is by far one of the most challenging chronic diseases to manage, and requires vigilant participation 100 percent of the time to stay well controlled.”

The iLet bionic pancreas helps patients manage their diabetes by both monitoring blood glucose levels and administering insulin and glucagon — a pancreatic hormone that raises blood sugar levels.

“In a traditional infusion pump, patients only have access to insulin to control glucose levels,” explains Meighan. “This can become problematic when it comes to hypoglycemia. The hope with a bi-hormonal system is that glucagon can be delivered during times that the glucose is low in order to stabilize levels without user interaction.”

Developed at Boston University by Edward Damiano, Ph.D., and Firas El-Khatib, Ph.D., the iLet is a hand-held device about the size of an iPhone but twice as thick, and can easily fit into a pocket. The unit consists of a dual chamber infusion pump that can be configured to deliver only insulin, only glucagon or both hormones. The device uses a wireless glucose sensor on the patient’s body to test blood sugar levels every five minutes. It then determines which hormone is needed and administers it via catheters connected to the patient.

In short-term studies, the iLet was able to maintain blood glucose levels close to normal in both adults and children in carefully controlled environments.

In 2016, the Children’s National Hospital Division of Endocrinology and Diabetes, led by diabetologist Fran Cogen, M.D., C.D.C.E.S., was one of several pediatric sites that were selected to participate in pivotal clinical trials to further test the efficacy of the bionic pancreas. In June 2020, the team at Children’s National began enrolling patients to test iLet devices that only deliver insulin. Once these initial studies are completed, the team will perform an additional trial to test iLet devices configured to deliver both insulin and glucagon.

“This trial is important as it represents the first dual chamber pump to manage glucose levels,” says Meighan. “It could potentially change the way we treat diabetes entirely. It represents a hope to our patients and families that one day this disease will have far less of a daily burden than it currently does.”

Currently, there are 18 patients enrolled in the clinical trial. An initial test run on two patients was successfully completed in November 2020. In early January 2021, the first patient was started on the bionic pancreas to begin the randomized controlled study and three additional patients, who completed the screening process, will join the study shortly. The screening and initiation of the study will continue in the remaining patients.

Study may change treatment of childhood growth disorders

little girl measuring her height

A new Phase 2 study at Children’s National will look at using the drug vosoritide to promote growth in children with growth disorders.

A child’s growth is often measured by pediatricians during routine physicals to identify abnormalities of growth and stature. An abnormality in these measurements could mean a child has a growth disorder. There are many different causes of growth disorders. Some can be the result of defects in genes related to the growth plate, which is the tissue near the end of long bones that grows as the child grows. Children with a growth disorder can present many different symptoms including short stature, joint pain, heart problems, bone problems and developmental delays. Scientists still have a lot to learn about what exactly causes these genetic growth disorders and treatments are limited, especially in the pediatric population. Growth hormone is not uniformly helpful and has only been approved for a small number of conditions.

Vosoritide is an investigational drug that directly targets the growth plate to promote growth. It is an analog of the amino acid C-type natriuretic peptide (CNP). It binds its receptor on healthy cartilage cells called chondrocytes and is currently under investigation in clinical trials as a treatment for the bone growth disorder achondroplasia.

“Vosoritide for Selected Genetic Causes of Short Stature” is a Phase 2 study currently open at Children’s National Hospital. This study will target five types of genetic short stature including SHOX deficiency, hypochondroplasia, Rasopathies (which includes Noonan syndrome), heterozygous NPR2 defects and CNP deficiency.

Thirty-five children with short stature will be enrolled and followed for a six-month observation period to obtain baseline growth velocity, safety profile and quality of life assessment. Study participants will then be treated with vosoritide for 12 months and will be assessed for safety and improvement in growth outcomes.

“Many patients who present with short stature likely have genetic defects in genes involved in growth plate physiology. Those patients with selected causes of short stature that interact with the CNP pathway may benefit from treatment with vosoritide, which directly targets the growth plate,” said Andrew Dauber, M.D., MMSc., lead investigator of this clinical study and chief of Endocrinology at Children’s National Hospital, a program ranked in the top 10 by U.S. News & World Report. “In this study, our goal is to understand if vosoritide may be a safe and effective treatment option for certain genetically defined short stature syndromes.”

This clinical trial has been approved by the FDA and funded by BioMarin. Children’s National is the only site in the world offering this therapy for patients with these conditions. The study is currently underway and subject recruitment is ongoing. There are 9 participants enrolled to date.

“This study could fundamentally change the way we treat certain growth disorders”, says Dr. Dauber.

DNA moleucle

Genetics can’t explain mixed impact of growth hormone therapy

DNA moleucle

Growth hormone therapy is one of the most common treatments for short stature in children. However, endocrinologists report mixed outcomes, even when children have the same underlying condition as the cause of their short stature. Despite research into a variety of potential causes for this unpredictable response, there is still very little scientific evidence to help physicians predict whether children with short stature who are treated with growth hormone will respond to the treatment or not.

A study published in the Journal of Clinical Endocrinology and Metabolism took up this question with an eye to the genetic factors that might predict response by conducting the first ever genome-wide association study of response to growth hormone.

“Previous disease-specific models have been developed using multiple clinical variables such as parental height, age at treatment start, peak hormone levels and doses, and birth parameters, however, these clinical parameters only partially predict variation in response,” wrote the study authors, including Andrew Dauber, M.D., first author and chief of the division of Endocrinology at Children’s National Hospital. “Our goal was to perform a large-scale genome-wide study to provide a comprehensive assessment of how common genetic variation may play a role in growth hormone response.”

To accomplish this, the study combined five cohorts from across the world to identify 614 individuals for further review. All patients had short stature caused by conditions including growth hormone deficiency, small for gestational age, or idiopathic short stature (no previously identified cause), who received growth hormone as treatment.

Interestingly, the researchers found no overwhelming genetic predictors of response to growth hormone. They did identify a few signals that may potentially play a role in the body’s response to growth hormone but noted those signals will need further exploration. The study also ruled out the idea that genetic predictors of height in the general population might predict response to growth hormone.

“Identifying genetic predictors of how a child with short stature will respond to growth hormone would be an important step forward for clinicians and parents to make informed decisions about the right treatment approach,” says Dr. Dauber. “Though we didn’t find any specific indicators, this large-scale study has allowed us to rule out some previously held assumptions and offers several new avenues to explore.”

The study was conducted in collaboration with Pfizer and Boston Children’s Hospital.

Children’s National Hospital in Washington, D.C., was ranked No. 7 nationally in the U.S. News & World Report 2020-21 Best Children’s Hospitals annual rankings. This marks the fourth straight year Children’s National has made the list, which ranks the top 10 children’s hospitals nationwide.

In addition, its neonatology program, which provides newborn intensive care, ranked No.1 among all children’s hospitals for the fourth year in a row.

For the tenth straight year, Children’s National also ranked in all 10 specialty services, with seven specialties ranked in the top 10.

“Our number one goal is to provide the best care possible to children. Being recognized by U.S. News as one of the best hospitals reflects the strength that comes from putting children and their families first, and we are truly honored,” says Kurt Newman, M.D., president and CEO of Children’s National Hospital.

“This year, the news is especially meaningful, because our teams — like those at hospitals across the country — faced enormous challenges and worked heroically through a global pandemic to deliver excellent care.”

“Even in the midst of a pandemic, children have healthcare needs ranging from routine vaccinations to life-saving surgery and chemotherapy,” said Ben Harder, managing editor and chief of Health Analysis at U.S. News. “The Best Children’s Hospitals rankings are designed to help parents find quality medical care for a sick child and inform families’ conversations with pediatricians.”

The annual rankings are the most comprehensive source of quality-related information on U.S. pediatric hospitals. The rankings recognize the nation’s top 50 pediatric hospitals based on a scoring system developed by U.S. News. The top 10 scorers are awarded a distinction called the Honor Roll.

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.

Below are links to the seven Children’s National specialty services that U.S. News ranked in the top 10 nationally:

The other three specialties ranked among the top 50 were cardiology and heart surgery, gastroenterology and gastro-intestinal surgery, and urology.

The Children’s National Research Institute recently released its 2019-2020 academic annual report, titled 150 Years Stronger Through Discovery and Care to mark the hospital’s 150th birthday. Not only does the annual report give an overview of the institute’s research and education efforts, but it also gives a peek in to how the institute has mobilized to address the coronavirus pandemic.

“Our inaugural research program in 1947 began with a budget of less than $10,000 for the study of polio — a pressing health problem for Washington’s children at the time and a pandemic that many of us remember from our own childhoods,” says Vittorio Gallo, Ph.D., chief research officer at Children’s National Hospital and scientific director at Children’s National Research Institute. “Today, our research portfolio has grown to more than $75 million, and our 314 research faculty and their staff are dedicated to finding answers to many of the health challenges in childhood.”

Highlights from the Children’s National Research Institute annual report

  • In 2018, Children’s National began construction of its new Research & Innovation Campus (CNRIC) on 12 acres of land transferred by the U.S. Army as part of the decommissioning of the former Walter Reed Army Medical Center campus. In 2020, construction on the CNRIC will be complete, and in 2012, the Children’s National Research Institute will begin to transition to the campus.
  • In late 2019, a team of scientists led by Eric Vilain, M.D., Ph.D., director of the Center for Genetic Medicine Research, traveled to the Democratic Republic of Congo to collect samples from 60 individuals that will form the basis of a new reference genome data set. The researchers hope their project will generate better reference genome data for diverse populations, starting with those of Central African descent.
  • A gift of $5.7 million received by the Center for Translational Research’s director, Lisa Guay-Woodford, M.D., will reinforce close collaboration between research and clinical care to improve the care and treatment of children with polycystic kidney disease and other inherited renal disorders.
  • The Center for Neuroscience Research’s integration into the infrastructure of Children’s National Hospital has created a unique set of opportunities for scientists and clinicians to work together on pressing problems in children’s health.
  • Children’s National and the National Institute of Allergy and Infectious Diseases are tackling pediatric research across three main areas of mutual interest: primary immune deficiencies, food allergies and post-Lyme disease syndrome. Their shared goal is to conduct clinical and translational research that improves what we know about those conditions and how we care for children who have them.
  • An immunotherapy trial has allowed a little boy to be a kid again. In the two years since he received cellular immunotherapy, Matthew has shown no signs of a returning tumor — the longest span of time he’s been tumor-free since age 3.
  • In the past 6 years, the 104 device projects that came through the National Capital Consortium for Pediatric Device Innovation accelerator program raised $148,680,256 in follow-on funding.
  • Even though he’s watched more than 500 aspiring physicians pass through the Children’s National pediatric residency program, program director Dewesh Agrawal, M.D., still gets teary at every graduation.

Understanding and treating the novel coronavirus (COVID-19)

In a short period of time, Children’s National Research Institute has mobilized its scientists to address COVID-19, focusing on understanding the virus and advancing solutions to ameliorate the impact today and for future generations. Children’s National Research Institute Director Mark Batshaw, M.D., highlighted some of these efforts in the annual report:

  • Eric Vilain, M.D., Ph.D., director of the Center for Genetic Medicine Research, is looking at whether or not the microbiome of bacteria in the human nasal tract acts as a defensive shield against COVID-19.
  • Catherine Bollard, M.D., MBChB, director of the Center for Cancer and Immunology Research, and her team are seeing if they can “train” T cells to attack the invading coronavirus.
  • Sarah Mulkey, M.D., Ph.D., an investigator in the Center for Neuroscience Research and the Fetal Medicine Institute, is studying the effects of, and possible interventions for, coronavirus on the developing brain.

Diabetes clinic helps undocumented children manage their chronic condition

insulin and syringes

A diabetes clinic gives undocumented children with diabetes access to the care they need to maintain their health with this chronic condition.

In 2018, Jennifer Boughton, a social worker at Children’s National Hospital, came up with the idea of starting a diabetes clinic for patients whose immigration status prevented them from qualifying for insurance. The idea came about after undocumented children were arriving in the emergency department with high blood sugar and dangerously elevated ketone levels.

Through donations and the employees, who volunteer their time, Boughton’s idea became a reality. In January of 2019, the diabetes center held its first access clinic. The clinic has been open every three months since then for undocumented children with diabetes.

Flyers for the clinic are sent to local schools and organizations to help recruit patients.

In the first year, the patient volume has quadrupled and the hbA1c levels have decreased for patients who attend.

Andrew Dauber, M.D., MMSc, caps off research success with award and reception

Andrew Dauber

Unfortunately, we’ve been notified that the ENDO2020 conference has been canceled due to concerns of COVID-19. Because of this, we will not be hosting our reception in honor of Andrew Dauber, M.D., on Sunday, March 29.

We hope to see you at a future Endocrinology or Pediatric Endocrinology event.

Children’s National Hospital is incredibly proud of the work Dr. Dauber has done in the endocrinology community.

Andrew Dauber, M.D., MMSc, division chief of Endocrinology at Children’s National Hospital, will be awarded the 2020 Richard E. Weitzman Outstanding Early Career Investigator Award at ENDO 2020. The prestigious award will be presented at the annual meeting of the Endocrine Society in recognition of Dauber’s work in understanding the regulation of growth and puberty, and applying innovative genetic technologies to studying pediatric endocrinology. Dauber credits many collaborators throughout the world, as well as the team at Children’s National for the award.

With a five-year grant from the National Institutes of Health (NIH), Dauber and colleagues from the Cincinnati Children’s Hospital Medical Center, Boston Children’s Hospital and the Children’s Hospital of Philadelphia are using electronic health records to identify children who likely have rare genetic growth disorders. Using cutting-edge DNA sequencing technologies, including whole exome sequencing, the researchers are aiming to identify novel genetic causes of severe growth disorders. The first paper describing genetic findings in patients with high IGF-1 levels was published in Hormone Research in Paediatrics in December 2019.

Dauber and researchers at Cincinnati Children’s Hospital Medical Center are exploring how to treat patients with mutations in the PAPPA2 gene. In 2016, the group described the first patients with mutations in this gene who had decreased the bioavailability of IGF-1, stunting their growth and development. In their current phase of research, findings are emphasizing the importance of this gene in regulating IGF-1 bioavailability throughout childhood. The ultimate aim is to create therapies to increase IGF-1 bioavailability, thereby supporting healthy growth and development in children. Their first study to track PAPPA2 and intact IBGBP-3 concentrations throughout childhood was published in the European Journal of Endocrinology in January 2020.

Dauber is particularly interested in studying children with dominantly inherited forms of short stature. Along with collaborators in Cincinnati, he currently has an ongoing treatment trial using growth hormone in patients with Aggrecan gene mutations.  Dauber hopes to announce soon a new clinical trial for children with all forms of dominantly inherited short stature.

Study upon study has shown us that there are many factors that affect an individual’s height and growth. As these studies and the conversation around how to identify and address genomic anomalies become more prevalent, the team at Children’s National is increasingly interested in engaging with other centers around the country. In the coming months, the Children’s National Research & Innovation Campus will open on the grounds of the former Walter Reed Army Medical Center, which will serve as a one-of-a-kind pediatric research and innovation hub. A critical component to this campus is the co-location of Children’s National research with key partners and incubator space.

Working to improve the management of endocrine related conditions

Nadia Merchant

This past fall, Nadia Merchant, M.D., joined Children’s National Hospital as an endocrinologist in the Endocrinology and Diabetes Department. Dr. Merchant received her undergraduate and medical education at Weill Cornell Medical College in Qatar. She completed her pediatric residency at Wright State Boonshoft School of Medicine. She then completed her genetics residency and pediatric endocrine fellowship at Baylor College of Medicine/Texas Children’s Hospital.

Dr. Merchant was born with acromesomelic dysplasia, a rare genetic disorder, but that hasn’t stopped her from pursuing her medical career. While at Baylor College of Medicine, Dr. Merchant was very active in quality improvement projects, research and organizations that raise awareness of endocrine related conditions. For several years, she was a moderator at Baylor College of Medicine for “From Stress to Strength,” at a course for parents of children with genetic disorders and autism. Dr. Merchant also served as an endocrine fellow representative on the American Academy of Pediatrics Section on Endocrinology (SOEn) for the last two years and also served on the committee for a Bone and Mineral special interest group within the Pediatric Endocrine Society (PES). During medical school, she worked with Positive Exposure, an organization that uses visual arts to celebrate human diversity for individuals living with genetic, physical, behavioral and intellectual differences.

During the 2019 Endocrine Society Annual Meeting, Dr. Merchant won the Presidential Poster Award for her poster presentation: Assessing Metacarpal Cortical Thickness as a Tool to Evaluate Bone Density Compared to DXA in Osteogenesis Imperfecta a research project assessing whether hand film is an additional tool to detect low bone mineral density in children.

Dr. Nadia Merchant is currently one of the endocrinologists in the multidisciplinary bone health clinic at Children’s National, a clinic dedicated to addressing and improving bone health in children. Dr. Merchant also manages endocrine manifestations in children with rare genetic disorders.

The Endocrinology department at Children’s National is ranked among the best in the nation by “U.S. News & World Report”.

Fewer than half of California pharmacies provide correct drug disposal info

expired drugs

Fewer than half of California pharmacies provided correct prescription drug disposal details, a percentage that dropped if “secret shoppers” made their call on a weekend, according to a brief research report published online Dec. 31, 2019, in Annals of Internal Medicine.

The callers pretended to be well-meaning parents who were trying to safely dispose of unneeded antibiotics and opioid-based prescription painkillers after their child’s surgery. Fewer than half of the California pharmacies they called provided correct prescription drug disposal details, a percentage that dropped sharply if the “secret shoppers” made their call on a weekend, according to a brief research report published online Dec. 31, 2019, in Annals of Internal Medicine.

“The Food and Drug Administration advises consumers about how to safely dispose of unneeded medicines and, because pharmacists can play an integral role in this conversation, the American Pharmacists Association says prescription medication disposal should follow FDA guidelines,” says Rachel E. Selekman, M.D., MAS, a pediatric urologist at Children’s National Hospital and the study’s first author. “We found very few California pharmacies permitted take-back of unneeded medications. There was also a striking difference in the accuracy and completeness of drug disposal information depending on whether they answered the call on a weekday or a weekend. That suggests room for improvement,” Dr. Selekman says.

The multi-institutional research team, led by Primary Investigator and senior author Hillary L. Copp, M.D., MS, at University of California, San Francisco, identified licensed pharmacies located in urban and rural settings in California. That state that accounts for 10% of all U.S. pharmacies. They wrote a script that guided four male and two female “secret shoppers” to ask about what to do about leftover antibiotics (sulfamethoxazole-trimethoprim tablets) and a liquid opioid-based painkiller (hydrocodone-acetaminophen). From late-February to late-April 2018, they called 898 pharmacies from 8 a.m. to 8 p.m., asking about the correct way to dispose of these medicines.

According to the FDA, consumers should mix most unused medicines with an unappealing substance, like kitty litter, place it in a sealed container and toss the container in the trash.  Medicines that can be harmful to others, like opioids, should be flushed down the sink or toilet. Many pharmacies have programs or kiosks to handle unused prescription medicines.

Of the pharmacies surveyed in California:

  • 47% provided correct information about disposing of antibiotics
  • 29% provided correct information about how to dispose of both antibiotics and opioids
  • 19% provided correct information about how to dispose of opioids
  • 49% provided correct antibiotic disposal information and 20% provided correct opioid disposal information on weekday calls
  • 15% provided correct antibiotic disposal information and 7% provided correct opioid disposal information on weekend calls

Asked specifically about drug take-back programs, just 11% said their pharmacy had one that could be used to dispose of antibiotics or opioids.

“Unused prescription medications can be misused by others and can result in accidental childhood poisonings,” Dr. Selekman adds. “The bottom line is that we often talk about how to address the problem of too many unused medications lingering in homes. There are many reasons this is a problem, but part of the problem is nobody knows what to do if they have too many prescription medicines. Because of this research, we have discovered that pharmacies don’t uniformly provide accurate information to our patients. Patients, families and health care professionals who advise families should work together to help improve and expand safe disposal options for these powerful medications.”

In addition to Drs. Selekman and Copp, the research team includes co-authors Thomas W. Gaither, M.D., MAS, Zachary Kornberg, BA, and Aron Liaw, M.D., all of whom were at the University of California, San Francisco, School of Medicine, Division of Pediatric Urology at the time the study was performed.

Brynn Marks

Bringing diabetes technology to patients and providers

Brynn Marks

Brynn Marks, M.D., endocrinologist at Children’s National Hospital, was diagnosed with Type 1 diabetes at the age of five years old and knows too well the struggles that may come with managing this chronic condition. After finding the right, knowledgeable provider as a teen, Dr. Marks realized that she wanted to become an endocrinologist and be that resource and support for others with Type 1.

Developments in diabetes technologies, including continuous glucose monitors (CGM) and insulin pumps, hold great promise for improving diabetes control while also improving quality of life for those living with Type 1. However, the pace of development also presents challenges for busy clinicians who must keep up with rapid developments in the field. Dr. Marks is focused on making sure patients and providers have the latest information and training on diabetes technologies with the goal that they can be more effectively used by more people in the real world.

“These diabetes technologies are very important for kids and teens with diabetes because they can help them to live life as normally as possible while affording the freedom they need to just be kids,” says Dr. Marks.

Dr. Marks’ recent research includes a study where she used an app to deliver medical education about diabetes technology. Participants received authentic, case-based scenarios focused on the technologies to help them apply knowledge of these technologies to real-world clinical scenarios involving insulin pumps and CGMs. All of the education was delivered through questions and explanations in an effort to keep the learners engaged with the curriculum. The questions were repeated over 3-4 months to improve learning and long-term knowledge retention. The study showed that knowledge and confidence about these technologies improved and ultimately led to better patient care.

Dr. Marks presented two posters at a recent International Society for Pediatric and Adolescent Diabetes (ISPAD) meeting related to her efforts to make these technologies more accessible:

Experiential Learning in T1D Technology Education: Knowledge of Parents and Clinicians: Dr. Marks enrolled different groups of learners in the diabetes technology curriculum mentioned above, including parents of children with Type 1 diabetes, attending physicians, pediatric endocrine fellows and certified diabetes educators. Results showed minimal difference among those groups in terms of knowledge about the pumps and CGMs. Interestingly, clinicians who had the opportunity to wear the technologies for educational purposes had greater knowledge than clinicians who did not have the same opportunity. Based on these results, Dr. Marks advocated that opportunities to wear pumps and CGMs should be a routine part of education for clinicians working with these technologies.

A Qualitative Analysis of Clinicians’ Experiences Wearing CGM: Dr. Marks explored the reactions of clinicians without diabetes who were given the opportunity to wear continuous glucose monitors for 1 week. Participants reported that the opportunity to wear these technologies improved their knowledge and gave them greater empathy for patients using CGM.

Dr. Marks’ work to date has identified strategies to improve knowledge about insulin pumps and CGM. Moving forward, she will continue to study the best ways to educate parents and clinicians about these diabetes technologies in hopes of improving the day to day lives of the children they care for.
