Allergic rhinitis and recurrent epistaxis in children

Area of Science:

• Pediatric Allergy and Immunology
• Otolaryngology
• Allergic Rhinitis Research

Background:

• Allergic rhinitis is often overlooked as a cause of childhood nosebleeds by otolaryngologists compared to allergists.
• Investigating the connection between allergic rhinitis and epistaxis in pediatric populations is crucial.

Purpose of the Study:

• To determine the relationship between allergic rhinitis and epistaxis in children.
• To ascertain if nasal symptoms alone can cause recurrent nosebleeds.

Main Methods:

• A consecutive series of 557 children referred to a pediatric allergy clinic were studied.
• Standardized parental questionnaires and skin prick tests for common inhalant allergens were employed.

Main Results:

• Children with both nasal symptoms and positive skin tests had a 20.2% rate of recurrent nosebleeds, significantly higher than other groups.
• Logistic regression showed an odds ratio of 3.3 for nosebleeds in children with both allergic rhinitis symptoms and positive skin tests.
• Pet ownership combined with specific allergies (e.g., to dogs or cats) further increased the incidence of nosebleeds.

Conclusions:

• Allergic rhinitis is frequently associated with recurrent epistaxis in children.
• Nasal symptoms in allergic children, possibly combined with an atopic-related hemostatic abnormality, contribute to nosebleeds.
• A disorder of hemostasis is suspected as a contributing factor to epistaxis in children with allergic rhinitis.
