Perennial rhinitis in Saudi Arabia. A prospective study
Annals of Allergy
|January 1, 1986
Summary
Allergy was confirmed in 54% of perennial rhinitis patients, with Bermuda grass as the most common allergen. Blood eosinophils and IgE tests are valuable for assessing perennial rhinitis.
Area of Science:
- Allergy and Immunology
- Otorhinolaryngology
Background:
- Perennial rhinitis is a common condition with unclear pathogenesis.
- Understanding the role of allergens and diagnostic tests is crucial for patient management.
Purpose of the Study:
- To investigate the pathogenesis of perennial rhinitis.
- To evaluate the clinical utility of various laboratory tests in diagnosing perennial rhinitis.
- To identify common allergens contributing to perennial rhinitis in Saudi Arabia.
Main Methods:
- Clinical examination of 100 consecutive perennial rhinitis patients.
- Comprehensive laboratory investigations including blood eosinophil and IgE level assessments.
- Allergen identification, with a focus on Bermuda grass.
Main Results:
- Allergy was confirmed in 54% of patients.
- Bermuda grass was identified as the most prevalent allergen.
- Eosinophilic rhinitis was present in 12% of cases.
- Blood eosinophil and IgE investigations proved valuable in patient assessment.
Conclusions:
- Allergy, particularly to Bermuda grass, plays a significant role in perennial rhinitis in the Eastern Province of Saudi Arabia.
- Blood eosinophil and IgE testing are recommended for assessing perennial rhinitis patients.
- Further research is needed to explore the connection between pollen allergy and perennial rhinitis in the region.
