Understanding true IgE-mediated food allergy
“Doc, do you think it’s a food allergy?” Whether you are a pulmonologist, an infectious disease specialist, or an allergist, chances are you’ve been asked this question and in a variety of clinical contexts. While the term “food allergy” is often misused by the lay population to describe a food intolerance, true IgE-mediated food allergy is the immediate degranulation of mast cells upon exposure to the allergen. Other types of food allergy exist, such as eosinophilic esophagitis and food protein induced enterocolitis syndrome, but the most common food allergy is IgE-mediated food allergy. Symptoms of IgE-mediated food allergy, which typically occur from a few minutes to a few hours after ingestion, include urticaria, angioedema, dyspnea, possibly hypotension and, in some cases, death. Epinephrine, not antihistamines, stops this reaction. Prompt administration of epinephrine results in better outcomes than does delayed administration of epinephrine. Nonetheless, schools of all types – private and public, preschools through high schools – continue to struggle with adopting effective policies that promote prompt recognition and treatment of anaphylaxis. In fact, many schools lack a practiced medical emergency response plan.1
Code Ana prepares schools for swift intervention
Schools today are challenged beyond educating our children. They must keep students safe and healthy throughout the school day and during after-school activities. Eight percent of children have food allergy,2 so schools need to be prepared for anaphylaxis. Government and advocacy groups have developed legislation, guidelines and tools to help schools be better prepared for medical emergencies;3-6 however, limited support is provided to schools in guiding non-medical school personnel in the development and implementation of medical emergency protocols. Rarely do schools have a practiced medical emergency response plan and team – a school’s version of a “Code Blue.” To fill this gap, I worked with school personnel, families, students, colleagues and the Code Ana program (www.CodeAna.org). Code Ana equips schools to prevent and be prepared for medical emergencies, like anaphylaxis (Figure 1).

The value of epinephrine training in schools
Mission-critical to anaphylaxis readiness in schools is medical education for school personnel. This need was underscored in the fall of 2017 when a young boy with food allergy and asthma accidentally ingested an allergen at his New York City preschool and subsequently died.7 Code Ana responded to this tragedy by developing Code Ana’s Epinephrine Training Program, which is approved by New York State as an epinephrine training course. In the fall of 2018, Code Ana donated this course to the NYC Department of Health, specifically for NYC daycare personnel. Also, I traveled to NYC to lead in-person epinephrine training workshops and answer questions about food allergy anaphylaxis. To date, over 8,000 day care personnel have successfully completed the online course, and epinephrine has already been used by Code Ana trainees in three real-life emergencies to treat anaphylaxis and prevent another tragedy.
Working together to keep our schools safe
In our quest to help schools, we continue to grow and share Code Ana, prescribe stock epinephrine auto-injectors through Cleveland Clinic Children’s School-Based Health Care and develop user-friendly medical emergency tracking and reporting tools.8 As a physician, you too have the unique opportunity to play a critical role in schools by sharing evidence-based information, thereby increasing safety and wellness for children and adults. If you are interested in participating in school-focused medical education that targets children or adults, please reach out to me. You have something invaluable to share, and it may save a life. Together, we can equip our schools to prevent and be prepared for medical emergencies. Teamwork makes the dream work!
