Keynote speaker Virginia Governor and pediatric neurologist, Ralph Northam, joined Dr. Kurt Newman, president and CEO of Children’s National Hospital, and Dr. Mark Batshaw, executive vice president, physician-in-chief and chief academic officer at Children’s National Hospital, during the 4th Annual Children’s National Hospital-NIAID Virtual Symposium.

Children’s National Hospital and the National Institute of Allergy and Infectious Diseases (NIAID) hosted their 4th annual symposium, attracting nationwide researchers, trainees and health care professionals to share updates on the COVID-19-related condition known as Multisystem Inflammatory Syndrome (MIS-C) in Children, allergy and immunology in the pediatric population.

“Children’s National relationship with the NIAID is a strategic and novel alliance that benefits children everywhere,” said Kurt Newman, M.D., President and CEO of Children’s National Hospital. “I’m so proud of our unique partnership and how it has enriched the high-quality research being conducted at Children’s National and enabled us to interact on pressing health issues. With the opening of our new Children’s National Research & Innovation Campus on the grounds of the former Walter Reed Army Medical Center, the sky is the limit to how we can work together with the NIAID to innovate for kids so that we help them grow up stronger.”

The discussions at the symposium centered around various topics, including clinical manifestations of SARS-CoV-2 in children, comparative disease biology manifestation in children and adults, therapies and vaccines in the pediatric setting, intersectionality of allergy, immunology and COVID-19, modulating biologic factors in immune regulation and treatments that invoke tolerance in allergy.

Keynote speaker Virginia Governor and pediatric neurologist, Ralph Northam, spoke about the COVID-19 pandemic and strategies to reintroduce children into schools and sports.

“Schools provide stability and structure. We know that children need to be in school for educational achievements and their mental health, but it has taken time to make school staff and families more comfortable with a greater time of in-person learning,” said Dr. Northam. “Our goal is to have all in-person learning this fall. That is where our children need to be because it is the safest place for children.”

During the keynote session, Dr. Northam also addressed the mental health issues related to the pandemic where pediatricians have seen an increase in depression and suicide rates.

“As we move forward to a back more normal life, we need to keep an eye on these children and make sure that they continue to get the support and treatment that they need,” said Dr. Northam.

The Clinical and Translational Science Institute at Children’s National (CTSI-CN) and the NIAID organized the 4th annual symposium and wished to showcase some of the critical research being done on this worldwide infectious disease, particularly amongst the pediatric population and those affected with allergic and immunologic disease. By sharing this work, they hope it will help continue to drive the advancement of pediatric research in relation to this disease.

The research partnership between Children’s National and the National Institute of Allergy and Infectious Diseases (NIAID) is devoted to protecting and advancing the health of children with allergic, immunologic, autoinflammatory and infectious diseases through collaborative research and education. The partnership co-hosts an annual symposium to disseminate new information about science related to the partnership.

Funding will help uncover immune system differences that trigger food allergies

Adora Lin

“When it comes to food allergies, we really don’t know how they develop. We don’t know how to best differentiate between a child who can safely eat a potential allergen, like peanuts, compared with a child who cannot safely eat peanuts.” says Adora A. Lin, M.D., Ph.D.

Adora A. Lin, M.D., Ph.D., an attending physician in Children’s department of Allergy and Immunology, was awarded $240,000 to improve understanding of how children’s immune systems tolerate or react to certain food allergens – sometimes triggering a cascade of side effects that can be fatal.

The three-year American Academy of Allergy, Asthma & Immunology (AAAAI) Foundation award will underwrite Dr. Lin’s ongoing research into the regulation of the antibody Immunoglobulin E (IgE), which plays a pivotal role in these allergic responses.

“Our immune system maintains a delicate balance, working just enough to ward off potential invaders and pathogens, but not so much that it triggers problems of its own making,” Dr. Lin says. “When it comes to food allergies, we really don’t know how they develop. We don’t know how to best differentiate between a child who can safely eat a potential allergen, like peanuts, compared with a child who cannot safely eat peanuts.”

Food allergies have become a growing problem and affect about 1 in 13 U.S. children, or about two per classroom. Food items such as eggs, milk, peanuts, tree nuts, soy and wheat trigger allergic reactions that can include itching, swelling, hives and difficulty breathing. As children’s immune systems react to exposure to such allergens, their B-cells produce IgE antibodies.

Apart from avoiding these foods and carrying rescue medications, which must be used immediately after accidental exposure, there is no way to treat food allergies effectively. That makes it essential to better understand how the immune system works in order to innovate new and better food allergy treatments and diagnostics.

Dr. Lin’s work involves isolating immune cells from blood samples, culturing them and stimulating an immune response to known food allergy triggers. B-cells make IgE, but additional clarity is needed about what turns on the “make IgE” signal as well as which signals indicate it’s time to stop making IgE. Ultimately, the aim is to identify biomarkers that are akin to the “check engine” light that illuminates to warn of a potential problem long before a car stalls in traffic.

“I’m very excited about this funding,” Dr. Lin adds. “Our field has done an exceptional job with clinical work to help children with food allergies. This award recognizes the importance of the mechanistic side of the equation. I’m excited to help make that contribution to the research.”

As it stands now, blood tests are sensitive to food-related IgE, but are not specific. Only 30 to 55 percent of children who have IgE to common food allergens have an allergic reaction after eating the food, which means that 45 to 70 percent are merely sensitized and could tolerate eating the food. Current tests cannot distinguish between sensitized and allergic children.

“Our hope is to identify biomarkers that would serve as the ‘check engine’ light that tell us in advance which child’s immune system will react strongly to that food. Right now, there is no way to tell. This project will help uncover those differences,” she says.

Dr. Lin was one of three recipients of the AAAAI Foundation’s faculty development award, which was presented during a March 3, 2018, award ceremony held during the organization’s business meeting.
