Summary
Drug-induced anaphylaxis, a severe allergic reaction, is rising. Prevention involves patient history and risk assessment, while management focuses on airway control and epinephrine. Early diagnosis and intervention are crucial.
Area of Science:
- Immunology
- Pharmacology
- Clinical Medicine
Background:
- Drug-induced anaphylaxis and anaphylactoid reactions are increasing with pharmaceutical use.
- Anaphylaxis is an IgE-mediated hypersensitivity reaction; anaphylactoid reactions are similar but not IgE-mediated.
- Antibiotics, NSAIDs, anesthetics, and radiocontrast media are common culprits, with penicillins being the most studied.
Purpose of the Study:
- To review the incidence, diagnosis, and management of drug-induced anaphylaxis.
- To highlight preventive strategies and diagnostic testing options.
- To outline emergency treatment and long-term identification for patients.
Main Methods:
- Review of existing literature on drug-induced hypersensitivity reactions.
- Discussion of diagnostic tools including skin tests and oral challenges.
- Emphasis on clinical assessment for prevention and management.
Main Results:
- Penicillins are the most common cause, with well-documented antigenic determinants.
- Diagnostic tests like IgE-specific skin tests and radioallergosorbent tests are available, though predictive values vary.
- Desensitization and dose escalation protocols can be used for high-risk patients.
Conclusions:
- Prevention through detailed patient history and risk assessment is key.
- Management requires rapid intervention, focusing on airway, breathing, and circulation, with epinephrine as primary treatment.
- Lifelong identification, such as Medic-Alert bracelets, is essential for patients with a history of anaphylaxis.
