[Penicillin Allergy - Deadly "Fake News" in the Medical Record?]

Area of Science:

• Clinical immunology
• Pharmacology
• Infectious diseases

Background:

• Penicillin allergy is frequently reported (8-12%) but often lacks specific diagnostic history.
• Hypersensitivity reactions are diverse, with true anaphylaxis being a small subset.
• Inaccurate allergy documentation can lead to adverse patient outcomes.

Purpose of the Study:

• To evaluate the risk stratification for penicillin allergy assessment.
• To identify reasons for unclear or incorrect allergy documentation.
• To describe the diagnosis and therapy of true penicillin anaphylaxis.

Main Methods:

• Review of literature on penicillin allergy prevalence and diagnostic approaches.
• Analysis of factors contributing to inaccurate allergy histories.
• Description of diagnostic methods for hypersensitivity reactions.
• Outline of treatment strategies for anaphylaxis.

Main Results:

• Simple patient surveys can help identify suitable cephalosporin candidates (e.g., cefazolin).
• Unclear antibiotic allergy histories necessitate stepwise allergological diagnosis.
• Suspected allergies are linked to higher postoperative infection rates and increased mortality.

Conclusions:

• Accurate penicillin allergy assessment is vital for patient safety.
• Systematic diagnostic approaches improve antibiotic selection and reduce adverse events.
• Proper documentation and evaluation of antibiotic hypersensitivity are essential clinical practices.
