New intervention program can help children with food allergies

November 2, 2023

Kids with food allergies can experience stress related to daily food allergy management.

Adolescence is a challenging developmental period associated with risky food allergy behaviors. Kids with food allergies can experience stress related to daily food allergy management. In fact, some kids report that they have anxiety about allergic reactions and get bullied for their allergies.

The big picture

In a new study published in the Annals of Allergy, Asthma and Immunology, a team of experts developed the Food Allergy Mastery Program (FAM), a six-session telehealth program led by a counselor that promotes food allergy self-management and adjustment for youth ages 10-14 years.

“We then conducted focus groups with families in our food allergy clinic to get their opinions on the program, made changes and conducted a pilot study with additional food allergy families,” said Linda Herbert, Ph.D., director of Psychology Research and Clinical Services for Allergy and Immunology and psychologist at Children’s National Hospital and author of the study. “When we compared kids’ food allergy knowledge, self-efficacy and social support before and after completing the FAM Program, we saw improvements in food allergy knowledge, greater self-efficacy and more social support after the program.”

What’s been the hold-up in the field?

To date, there are no behavioral interventions that promote food allergy self-management and adjustment for youth. However, Herbert said such an intervention is critically needed because adolescence is a higher-risk period for allergic reactions.

“Adolescents are typically diagnosed when they are young and may not have sufficient food allergy knowledge about how to engage in food allergy self-management,” Herbert said.

They also spend an increasingly greater amount of time with peers, so they are more responsible for their food allergy, she added.

What’s exciting about the findings?

Youth who completed all six sessions rated the FAM Program as relevant and enjoyable on the post-program evaluation. They also reported having better knowledge related to allergen avoidance, allergic reaction symptom recognition and allergic reaction treatment.

“The FAM Program is a promising intervention for youth with food allergies,” the authors wrote.

What’s next?

From here, the team is conducting a large-scale randomized clinical trial to fully evaluate the FAM Program’s impact on kids funded by the National Institute of Allergy and Infectious Diseases. This trial is evaluating the impact of the FAM Program on primary outcomes of interest, such as food allergy knowledge, skills, behavior and psychosocial functioning, and distal outcomes of interest, such as healthcare utilization.

Food allergy-related bullying assessment methods don’t fully capture hurdles

October 6, 2021

When asked a simple “yes” or “no” question about food allergy-related bullying, 17% of kids said they’d been bullied, teased or harassed about their food allergy. But when asked to reply to a multi-item list of victimization behaviors, that number jumped to 31%.

Living with a food allergy can greatly impact a child’s everyday life – from limiting participation in social activities to being treated differently by peers. While previous research indicates many kids experience food allergy-related bullying, a new study in the Journal of Pediatric Psychology found that offering kids with food allergies a multi-question assessment gives a more accurate picture of the size and scope of the problem.

When asked a simple “yes” or “no” question about food allergy-related bullying, 17% of kids said they’d been bullied, teased or harassed about their food allergy. But when asked to reply to a multi-item list of victimization behaviors, that number jumped to 31%. Furthermore, Children’s National Hospital researchers found that only 12% of parents reported being aware of it.

The reported bullying ranged from verbal teasing or criticism to more overt acts such as an allergen being waved in their face or intentionally put in their food. Researchers say identifying accurate assessment methods for this problem are critical so children can get the help they need.

“Food allergy-related bullying can have a negative impact on a child’s quality of life. By using a more comprehensive assessment, we found that children with food allergies were bullied more than originally reported and parents may be in the dark about it,” says Linda Herbert, Ph.D., director of the Psychosocial Clinical and Research Program in the Division of Allergy and Immunology at Children’s National and one of the study’s researcher.

“The results of this study demonstrate a need for greater food allergy education and awareness of food allergy-related bullying among communities and schools where food allergy-related bullying is most likely to occur,” Herbert adds.

The study looked at food allergy-related bullying among a diverse patient population and evaluated parent-child disagreement and bullying assessment methods. It included 121 children and 121 primary caregivers who completed questionnaires. The children ranged in age from 9 to 15-years-old and were diagnosed by an allergist with at least one of the top eight IgE-mediated food allergies – peanut, tree nut, cow’s milk, egg, wheat, soy, shellfish and fish.

Of the 41 youth who reported food allergy-related bullying:

51% reported experiencing overt physical acts such as an allergen being waved in their face, thrown at them or intentionally put in their food.
66% reported bullying experiences that are categorized as non-physical overt victimization acts including verbal teasing, remarks or criticisms about their allergy and verbal threats or intimidation.
Eight reported relational bullying, such as rumors being spread, people speaking behind their back and being intentionally ignored or excluded due to their food allergy.

The researchers also note that food allergy bullying perpetrators included, but were not limited to, classmates and other students, and bullying most commonly occurred at school.

The authors found that only 12% of parents reported that their child had been bullied because of their food allergy and of those, 93% said their child had reported the bullying to them. Some parents reported they had been made fun of or teased themselves because of concerns about their child’s food allergy.

“It’s important to find ways for children to open up about food allergy-related bullying,” Herbert says. “Asking additional specific questions about peer experiences during clinic appointments will hopefully get children and caregivers the help and support they need.”

Children’s National Research Institute releases annual report

May 19, 2020

Children’s National Research Institute directors Vittorio Gallo, Ph.D., and Mark Batshaw, M.D.

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 150^th 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.

Newborns with suspected food allergies breastfed significantly longer

February 26, 2019

Mothers whose newborns had suspected food allergies reported breastfeeding them significantly longer than women whose infants had no adverse reactions after food exposure, according to preliminary research led by Karen A. Robbins, M.D., and presented during the American Academy of Allergy, Asthma & Immunology 2019 Annual Meeting.

According to the Centers for Disease Control and Prevention (CDC), food allergies affect 4 to 6 percent of U.S. children, making such allergies a growing public health concern. Researchers are attempting to learn more about the interplay between food allergies and what, when and how children eat to inform allergy-prevention efforts. Little is known about the association between perceived food allergies, intolerance or hypersensitivity among babies eating their first bites of solid food and how long they’re breastfed.

Dr. Robbins and colleagues analyzed data gathered through a longitudinal study led by the Food and Drug Administration (FDA) and the CDC from 2005 to 2007. The Infant Feeding Practices Study II tracked diet and feeding practices of about 2,000 women late in their pregnancies and followed their babies’ diets through the first year of life.

Some 2,586 breastfeeding mothers in the study completed surveys when their infants were 4, 9 and 12 months old. The women were asked whether there were problems caused by food, such as an allergic reaction, sensitivity or intolerance. The majority of these infants (84.6 percent) had no suspected allergic reaction to either food they ate on their own or to food they were exposed to via breastmilk. The mothers reported that nearly 11 percent of infants reacted to something they ate; 2.4 percent reacted to food products they were exposed to via breastmilk; and 2.4 percent reacted to both food they consumed directly or were exposed to via breastfeeding. They also found:

Infants with suspected food allergies after exposure to food their mothers ate were breastfed a mean of 45.8 weeks.
Infants with food intolerance after both exposure to food their mother consumed and food they ate themselves were breastfed a mean of 40.2 weeks.

That contrasts with infants with no concern for food reactions, who were breastfed a mean of 32 weeks.

“Breastfeeding a newborn for the first few months of life helps their developing immune system become more robust, may affect the microbiome, and could influence or prevent development of allergy later in life,” says Dr. Robbins, an allergist at Children’s National Health System and lead author of the research. “However, mothers’ perceptions of their newborns’ adverse reactions to food appears to factor into how long they breastfeed.”

One potential concern is that extended breastfeeding can impact solid food introduction practices.

“Gradually transitioning to solid food gives infants an opportunity to sample an array of foods, nibble by nibble, including food allergens like peanut and eggs. We know from previously published research that introducing high-risk babies to a food allergen like peanuts early in life appropriately primes their immune system and dramatically decreases how often these children actually develop peanut allergies,” Dr. Robbins adds. “The relationship between breastfeeding and allergy development is complex, so understanding mothers’ practices is important. We also do not know how often these early reactions result in true food allergy, compared with transient food intolerance.”

Food allergies: a research update

February 25, 2019

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.”
