Diagnosing Allergic Rhinitis and Local Allergic Rhinitis.

Area of Science:

• Allergology
• Immunology
• Otorhinolaryngology

Background:

• Allergic rhinitis (AR) is a common condition diagnosed via clinical history and allergy tests like skin prick tests or serum-specific IgE (sIgE).
• Some patients exhibit AR symptoms despite negative conventional allergy test results, indicating a distinct condition.
• This subset of patients may have Local Allergic Rhinitis (LAR), characterized by nasal mucosal IgE production.

Purpose of the Study:

• To provide an overview of current diagnostic methods for allergic rhinitis (AR).
• To explore emerging insights into the identification and diagnosis of Local Allergic Rhinitis (LAR).

Main Methods:

• Review of current diagnostic approaches for AR.
• Discussion of diagnostic criteria and methods for LAR, including nasal allergen provocation testing and nasal sIgE detection.

Main Results:

• Conventional allergy tests (skin prick, serum sIgE) are standard for AR diagnosis.
• Local Allergic Rhinitis (LAR) is identified by localized nasal IgE production.
• Nasal allergen provocation testing and nasal sIgE detection are key for LAR diagnosis.

Conclusions:

• LAR represents a specific phenotype of allergic rhinitis requiring distinct diagnostic strategies.
• Accurate diagnosis of LAR is crucial for appropriate patient management and treatment.
• Further research into LAR pathophysiology and diagnostics is warranted.
