Area of Science:

  • Immunology
  • Allergology
  • Otorhinolaryngology

Background:

  • Allergic rhinitis is a prevalent condition.
  • Local nasal immunotherapy (LNIT) shows promise for treating allergic rhinitis.
  • Further validation of LNIT's efficacy is needed.

Purpose of the Study:

  • To confirm the clinical validity and efficacy of local nasal immunotherapy (LNIT).
  • To evaluate LNIT's effectiveness in patients with Parietaria and Dermathophagoides allergies.

Main Methods:

  • A randomized, double-blind, placebo-controlled trial was conducted.
  • Patients underwent symptom and medication scoring.
  • Nasal reactivity, rhinomanometry, and mucociliary clearance were assessed pre- and post-treatment.

Main Results:

  • LNIT significantly reduced clinical symptoms and medication use compared to placebo.
  • A significant decrease in allergen-specific nasal reactivity was observed in the LNIT group.
  • No adverse local or systemic side effects were reported.

Conclusions:

  • LNIT demonstrates clinical efficacy in the prophylaxis of allergic rhinitis.
  • LNIT is a safe and effective treatment option.
  • LNIT can be safely combined with conventional drug treatments.
