Anaphylaxis: Advances in the Past 10 Years

Area of Science:

• Allergy-Immunology research
• Mast cell biology
• Clinical immunology

Background:

• Anaphylaxis has emerged as a distinct subspecialty in Allergy-Immunology over the last decade.
• Significant progress has been made in understanding and managing anaphylaxis at both research and clinical levels.

Approach:

• Review of key clinical and research advancements in anaphylaxis over the past 10 years.
• Focus on diagnostic criteria, mast cell regulation, novel causes, and therapeutic strategies.

Key Points:

• Simplified diagnostic criteria and objective severity grading for anaphylaxis.
• Enhanced understanding of mast cell regulation, disorders, and hereditary α-tryptasemia.
• Identification of new causes (e.g., α-gal), pathways (e.g., MRGPRX2), and risk factors for severe anaphylaxis.
• Confirmation of epinephrine autoinjector stability under various conditions, with heat sensitivity noted.
• Emergence of novel preventive treatments targeting IgE receptor and intracellular signaling.

Conclusions:

• The past decade has yielded substantial progress in the diagnosis, understanding, and treatment of anaphylaxis.
• Ongoing research continues to refine management strategies and identify new therapeutic avenues for severe allergic reactions.
