Food-induced anaphylaxis is increasing, posing a significant risk, especially for atopic individuals. Carrying emergency adrenaline (epinephrine) is crucial for survival, highlighting the need for accessible treatments like inhalers.

Area of Science:

  • Allergy and Immunology
  • Epidemiology
  • Public Health

Background:

  • Population-based epidemiologic studies on food-induced anaphylaxis prevalence are lacking.
  • Anaphylaxis cases, particularly food-induced, have increased in the UK.
  • Fatal anaphylaxis often involves respiratory arrest, with atopic individuals and asthmatics at high risk.

Purpose of the Study:

  • To highlight the growing concern of food-induced anaphylaxis.
  • To identify high-risk populations and situations.
  • To advocate for improved emergency treatment accessibility.

Main Methods:

  • Analysis of UK hospital discharge statistics for anaphylaxis trends.
  • Review of UK fatal anaphylaxis register data.
  • Identification of common food allergens and high-risk environments.

Main Results:

  • Significant increase in anaphylaxis hospital discharges from 1991-92 to 1994-95.
  • Food-induced anaphylaxis showed a greater increase than overall anaphylaxis.
  • Fatal cases were associated with respiratory arrest; common risk factors include hidden allergens, dining out, and lack of emergency adrenaline.

Conclusions:

  • Food-induced anaphylaxis is a growing public health issue.
  • Atopic individuals with asthma are particularly vulnerable.
  • Improved accessibility to emergency adrenaline, potentially via inhalers, is recommended to reduce fatalities.
