Long-term clinical course of hypersensitive rhinitis

Area of Science:

• Allergy and Immunology
• Clinical Medicine
• Longitudinal Studies

Background:

• Hypersensitive rhinitis, encompassing both atopic and intrinsic types, presents a significant clinical challenge.
• Understanding the long-term prognosis of hypersensitive rhinitis is crucial for patient management and treatment strategies.

Purpose of the Study:

• To investigate the long-term clinical course and symptom evolution of hypersensitive rhinitis over approximately 18 years.
• To compare symptom changes between atopic and intrinsic rhinitis subtypes.

Main Methods:

• A follow-up questionnaire study was conducted on 180 patients from a previous allergological study.
• Data collection focused on symptom severity and resolution over an 18.2-year period.
• Patients were categorized into atopic (verified by allergological investigations) and intrinsic rhinitis groups.

Main Results:

• Over 18 years, 37.2% of patients reported decreased symptom severity, and 27.2% experienced complete symptom cessation.
• Complete disappearance of symptoms was significantly more frequent in the intrinsic rhinitis group compared to the atopic rhinitis group.
• The study included 72 men and 108 women, with a mean age of 28.5 years at the initial study.

Conclusions:

• Hypersensitive rhinitis often demonstrates a favorable long-term clinical course with a substantial proportion of patients experiencing symptom improvement or resolution.
• Intrinsic rhinitis may have a better prognosis regarding complete symptom resolution than atopic rhinitis.
• Longitudinal data are essential for understanding the natural history of allergic and non-allergic rhinitis.
