The current state of the knowledge about local allergic rhinitis

Area of Science:

• Allergy and Immunology
• Otorhinolaryngology

Background:

• A distinct phenotype of rhinitis involves localized specific IgE production without systemic atopy.
• This condition is termed local allergic rhinitis (LAR).

Purpose of the Study:

• To provide an updated review of current knowledge on local allergic rhinitis.
• To highlight unresolved aspects of LAR's pathophysiology and clinical behavior.

Main Methods:

• Literature review of recent studies on local allergic rhinitis.
• Synthesis of information on physiopathological mechanisms and clinical presentation.

Main Results:

• LAR is characterized by nasal-specific IgE, differentiating it from allergic rhinitis with systemic sensitization.
• Understanding LAR's unique mechanisms is crucial for targeted therapeutic development.

Conclusions:

• Further research is needed to fully elucidate the unresolved aspects of local allergic rhinitis.
• Improved understanding of LAR will lead to better management strategies and enhanced patient quality of life.
