Anaphylaxis Epidemiology and Risk Factors

Area of Science:

• Allergy and Immunology
• Epidemiology
• Public Health

Background:

• Anaphylaxis is a critical, life-threatening allergic reaction impacting all age groups.
• Global prevalence of anaphylaxis is rising, influenced by diagnostic improvements, new treatments, and environmental shifts.
• Epidemiological patterns of anaphylaxis vary significantly based on the specific trigger.

Purpose of the Study:

• To analyze the current epidemiology of anaphylaxis.
• To identify factors contributing to the increasing prevalence of anaphylaxis.
• To highlight risk factors associated with severe or fatal anaphylaxis.

Main Methods:

• Review of global research and epidemiological data on anaphylaxis.
• Analysis of contributing factors to prevalence changes.
• Identification and categorization of risk factors for severe anaphylaxis.

Main Results:

• Anaphylaxis prevalence is increasing worldwide, driven by improved diagnostics, therapies, climate change, and guideline updates.
• Older age, lung disease, cardiovascular conditions, and certain medications (beta-blockers, ACE inhibitors) are linked to severe anaphylaxis.
• Risk factors and prevalence differ based on the anaphylactic trigger.

Conclusions:

• Understanding anaphylaxis epidemiology is crucial for public health strategies.
• Identifying high-risk populations can guide preventative measures and therapeutic interventions.
• Further research into anaphylaxis triggers and risk stratification is warranted.
