A groundbreaking consensus report on anaphylaxis—an acute allergic reaction triggered by factors like bee stings, peanut butter exposure, medications, and more—has been released by the Global Allergy and Asthma Excellence Network (GA2LEN) and recently published in The Journal of Allergy and Clinical Immunology. The report, developed by an international panel of medical experts and patient advocacy organizations, aims to standardize the definition of anaphylaxis and improve global recognition and management of the condition.
A Critical Health Concern
Anaphylaxis, while rare, is a serious and life-threatening condition. Symptoms can include hives, swollen lips and tongue, difficulty breathing, wheezing, vomiting, and fainting. It requires rapid identification and treatment, often through the administration of epinephrine (commonly known as an epi-pen), which can reduce the risk of severe outcomes, including hospitalization and death.
However, only a small percentage of individuals experiencing anaphylaxis are treated with epinephrine. According to the report, just 21% of children and 7% of adults who experience anaphylaxis in community settings receive the essential treatment. This underuse of epinephrine is also seen in emergency departments, leading to calls for better treatment protocols.
The Need for Standardization
Tim Dribin, MD, an emergency medicine expert at Cincinnati Children’s and co-chair of the study, explained the report’s focus on the need for consistent, international guidelines. “Many people, including children and adults, carry epinephrine injectors to self-treat in emergencies, but many others do not. Our medical system, from first responders to hospital staff, does not consistently follow uniform guidelines for diagnosing and treating anaphylaxis. This report aims to address this lack of standardization,” Dr. Dribin stated.
The new report includes updated clinical criteria for diagnosing anaphylaxis, detailed guidance on the use and dosing of intramuscular epinephrine, and additional considerations for managing anaphylaxis in infants—an important inclusion to improve outcomes for young children.
An International Collaboration
The consensus report is the result of efforts from 46 experts across 14 countries and seven medical specialties, receiving endorsements from 34 medical and patient advocacy organizations. Significant contributions came from the National Institutes of Health (NIH), the U.S. Food and Drug Administration (FDA), and the European Medicines Agency (EMA), among others.
Game-Changing Clinical Support Tool
Dr. Hugh Sampson, MD, a leading food allergy and anaphylaxis expert at Mount Sinai School of Medicine and chair of the study, hailed the report as a “game-changer” in anaphylaxis management. “By improving the rate of epinephrine use, we can significantly reduce the risk of severe reactions and fatalities, ultimately saving lives,” Dr. Sampson said. He believes the report will also help drive cutting-edge research to further improve care for anaphylaxis patients.
Co-chair Dr. Antonella Muraro, MD, PhD, a renowned pediatric allergist at the University of Padova in Italy, emphasized the report’s importance for a wide range of healthcare professionals, including first responders, emergency department staff, allergists, and hospital providers. “The report will ensure timely and appropriate treatment, potentially saving lives and improving patient outcomes worldwide,” Dr. Muraro added.
Key Highlights of the Report
Unified Definition of Anaphylaxis: The report introduces a clear, widely accepted definition of anaphylaxis, emphasizing its life-threatening potential and the organ systems involved. This definition is designed to be accessible to both healthcare professionals and the general public, helping to raise awareness of the condition.
Educational Overview: The report includes an innovative educational tool aimed at healthcare professionals from various medical fields, training backgrounds, and experience levels. It offers essential information on recognizing and managing anaphylaxis, including common triggers, symptoms, and the importance of timely epinephrine treatment.
Clinical Support Tool: A new clinical support tool helps healthcare providers diagnose and treat anaphylaxis, featuring updated clinical criteria, indications for epinephrine, and common findings across different organ systems. This tool is the first to incorporate distinct findings for infants, improving anaphylaxis management for young children.
Looking Ahead
This new consensus report is a major step toward improving anaphylaxis treatment globally. With a unified approach to diagnosis, treatment, and education, the report aims to save lives by ensuring that patients receive the timely and appropriate care they need, no matter where they are in the world. The collaboration between medical experts, patient advocacy organizations, and regulatory bodies underscores the global commitment to tackling this serious and often misunderstood condition.
