Insights

Saline nasal irrigation using the Nasir® device effectively reduced inflammation in children with allergic rhinitis. This treatment lowered neutrophil and eosinophil counts in nasal cytology, improving upper airway inflammation.

Area of Science:

  • Pediatric Allergy and Immunology
  • Rhinology
  • Medical Device Technology

Background:

  • Allergic rhinitis (AR) and upper airway infections significantly impact children's quality of life, school performance, and family well-being.
  • Saline nasal irrigation is a common method to alleviate nasal symptoms and improve nasal cavity clearance.

Purpose of the Study:

  • To evaluate the efficacy of nasal irrigation with the Nasir® device on nasal cytology in children diagnosed with allergic rhinitis.
  • To assess the impact of this intervention on inflammatory markers within the nasal passages.

Main Methods:

  • A pilot study involving 66 children (aged 4-17 years) with allergic rhinitis.
  • Participants underwent nasal irrigation using the Nasir® device with a warm saline solution (36°C), one 250 mL sac twice daily for 12 days.
  • Nasal cytology was analyzed pre- and post-treatment to quantify inflammatory cell infiltration.

Main Results:

  • Nasal irrigation significantly reduced neutrophilic infiltrate (p < 0.05) and eosinophilic infiltrate (p < 0.05) in nasal cytology.
  • No significant changes were observed in bacterial counts post-treatment (p = 0.17).
  • The Nasir® device demonstrated a reduction in key inflammatory markers associated with allergic rhinitis.

Conclusions:

  • Nasal irrigation with the Nasir® device may be a beneficial adjunctive therapy for attenuating upper airway inflammation in pediatric allergic rhinitis.
  • This pilot study suggests a potential role for the Nasir® device in managing allergic rhinitis symptoms by reducing nasal inflammation.
