Anaphylaxis: clinical concepts and research priorities

Area of Science:

• Immunology
• Emergency Medicine
• Clinical Pharmacology

Background:

• Anaphylaxis is a severe, life-threatening hypersensitivity reaction.
• Diagnosis can be challenging, lacking a universally accepted clinical definition and reliable biomarkers.
• Current management is largely based on expert opinion and retrospective data.

Purpose of the Study:

• To review the current understanding and management of anaphylaxis.
• To highlight the need for prospective validation of diagnostic criteria and treatment strategies.
• To emphasize the necessity for high-quality research, including multicenter collaboration.

Main Methods:

• Review of existing literature on anaphylaxis diagnosis and management.
• Discussion of proposed consensus definitions for anaphylaxis.
• Analysis of current treatment modalities including adrenaline administration, volume resuscitation, and supportive therapies.

Main Results:

• A consensus definition for anaphylaxis is proposed for validation.
• Intramuscular adrenaline is the recommended initial treatment; intravenous infusion may be safer for subsequent doses.
• Management of refractory cases involves aggressive resuscitation, vasopressors, and inotropes.

Conclusions:

• Validated diagnostic criteria and outcome measures are crucial for advancing anaphylaxis research.
• High-quality prospective observational studies and randomized controlled trials are needed.
• A systematic, collaborative approach is essential to enhance the understanding and management of anaphylaxis.
