Latex Allergy - From Discovery to Component-resolved Diagnosis

Area of Science:

• Allergy and Immunology
• Dermatology
• Occupational Health

Background:

• Latex allergy involves hypersensitivity to natural rubber latex (NRL) proteins or manufacturing chemicals.
• Accurate diagnosis is vital for managing latex allergy, particularly in high-risk groups like healthcare workers and individuals with spina bifida.

Purpose of the Study:

• To review current diagnostic techniques for latex allergy.
• To analyze diagnostic algorithms used in clinical practice.
• To explore potential future developments in latex allergy diagnostics.

Main Methods:

• Review of existing literature on latex allergy diagnosis.
• Analysis of allergological evaluation methods, including skin prick tests and serological assays for IgE-mediated reactions.
• Evaluation of patch testing for T cell-mediated contact dermatitis.

Main Results:

• Type I hypersensitivity (IgE-mediated) is diagnosed via skin prick tests or latex-specific IgE (sIgE) antibody detection.
• Type IV hypersensitivity (T cell-mediated) is diagnosed using patch tests for rubber additives.
• Basophil activation and challenge tests may be used when clinical history conflicts with other test results.

Conclusions:

• Current diagnostic approaches effectively differentiate between type I and type IV latex hypersensitivity.
• Standardized diagnostic algorithms are essential for consistent patient management.
• Future research may focus on refining existing tests and developing novel diagnostic tools for latex allergy.
