Increasing cases of anaphylaxis among children

Anaphylaxis, known to be a sudden and potentially life–threatening allergic reaction, seems to be increasing among children, according to a new study led by a team at the Research Institute of the McGill University Health Centre (RI–MUHC). The findings, published in the Journal of Allergy and Clinical Immunology (JACI), reveal that the percentage of emergency department (ED) visits due to anaphylaxis doubled over a four–year period based on data collected from the Montreal Children’s Hospital of the MUHC (MCH–MUHC). The study shows that between 2011 and 2015, the annual percentage of ED visits to the MCH–MUHC due to anaphylaxis rose from 0.20% to 0.41%, with the largest annual increase between 2013–14 and 2014–15. The team also observed that the majority (80.2%) of anaphylaxis cases were triggered by food, principally peanut and tree nut, and that children who did not receive epinephrine prior to arrival at the ED were more likely to receive multiple (two or more) doses of epinephrine at the hospital. The underuse of epinephrine auto–injectors was also highlighted in the research. “Only slightly more than half of those who had an auto–injector used it prior to arrival in the emergency department,” adds the study’s lead author Dr. Elana Hochstadter, who is currently doing a fellowship in Pediatric Emergency Medicine at SickKids, and who was a pediatric resident at the Children’s Hospital at London Health Sciences Centre at the time of the study. “This increased the risk of administration of multiple epinephrine doses in hospital, therefore, it is of critical importance for parents and healthcare providers to work together to ensure the appropriate and timely use of epinephrine auto–injectors in the case of anaphylactic reactions.”
