The role of allergy in sinusitis in children
1Northwest Asthma and Allergy Center, Seattle, Wash.
Insights
Allergic rhinitis significantly contributes to sinusitis, affecting 25-70% of patients. Children with allergies face higher sinusitis risks due to anatomical and environmental factors.
Area of Science:
- Otolaryngology
- Allergy and Immunology
Background:
- Allergic rhinitis and sinusitis are common, often co-occurring conditions.
- High comorbidity (25-70%) suggests a link beyond chance prevalence.
Purpose of the Study:
- To explore the association between allergic rhinitis and sinusitis.
- To identify risk factors for sinusitis, particularly in children.
Main Methods:
- Literature review of studies examining allergic rhinitis and sinusitis.
- Analysis of prevalence data and associated risk factors.
Main Results:
- Allergy is a significant associated factor in sinusitis.
- Younger children have increased sinusitis risk due to anatomy, infections, and allergens.
- Immunodeficiency is linked to severe, resistant sinusitis.
Conclusions:
- Allergic rhinitis plays a key role in the development and persistence of sinusitis.
- Pediatric sinusitis is influenced by anatomical, infectious, and allergic factors.
- Immunodeficiency warrants consideration in refractory sinusitis cases.
Abstract:
Allergic rhinitis and sinusitis are independently common disorders. Studies document the presence of both disorders in the same patient 25% to 70% of the time. Because this is above the prevalence of allergic rhinitis in the general population, the literature supports that allergy is an important associated factor in sinusitis. Younger children appear to be even more at risk of sinusitis, perhaps because of small anatomic structures, more frequent viral infections, and more exposure to indoor allergens and irritants. Immunodeficiency appears to play an independent role in resistant, severe sinusitis.

Asthma is classified as allergic and non-allergic. Allergens such as dust mites, pollen, and pet dander trigger allergic asthma, while factors like cold air, intense emotions, or exercise can induce non-allergic asthma.

Mast cell stabilizers, such as cromolyn (also known as sodium cromoglycate) and nedocromil (Tilade), are effective drugs in asthma management. These stabilizers hinder histamine release by skillfully obstructing the activation of mast cells and other cellular entities. Notably, they navigate this task without...
