Insights
Spirometry during nasal breathing effectively measures nasal obstruction in children with allergic rhinitis. Nasal challenges can also reveal bronchospasm, indicating a link between nasal and airway inflammation.
Area of Science:
- Pediatric Pulmonology
- Allergy and Immunology
- Respiratory Physiology
Context:
- Chronic allergic rhinitis impacts children's respiratory health.
- Assessing nasal patency is crucial for understanding associated respiratory issues.
- Limited data exists on respiratory function during nasal ventilation in this population.
Purpose:
- To evaluate respiratory functions in children suffering from chronic allergic rhinitis.
- To determine the utility of spirometry during nasal ventilation for assessing nasal obstruction.
- To investigate the occurrence of bronchospastic reactions following nasal provocation tests.
Summary:
- Spirometric measurements during nasal ventilation objectively quantify nasal patency disturbances.
- Histamine and allergen nasal challenges were employed to assess airway responses.
- Bronchospastic reactions were observed post-nasal provocation, suggesting interconnected airway inflammation.
Impact:
- Spirometry during nasal breathing offers a valuable, objective method for evaluating nasal obstruction in pediatric allergic rhinitis.
- Findings highlight the potential for nasal challenges to unmask lower airway reactivity.
- This research aids in understanding the complex interplay between upper and lower airway disease in allergic rhinitis.
Abstract:
The aim of the paper is to assess respiratory functions in children with chronic allergic rhinitis. Multiple spirometric measurements were performed during oral and nasal ventilation and after nasal provocation with histamin and allergen. We find that spirometric measurements during nasal ventilation are very useful because they objectivize the degree of nasal patency disturbances. We have also noted the occurrence of bronchospastic reactions after nasal provocations.
