The effect of budesonide on the cytokine pattern in patients with perennial allergic rhinitis.

Abstract

BACKGROUND:

A T(H)2-polarized cytokine pattern has been demonstrated in allergic rhinitis. Budesonide represents an effective topical corticosteroid in the management of allergic rhinitis.

OBJECTIVE:

To evaluate cytokine pattern and symptoms in patients with perennial allergic rhinitis before and after treatment with intranasal budesonide.

METHODS:

All patients received budesonide aqueous nasal spray or placebo for 2 weeks. The study was double-blind, parallel group, placebo controlled, and randomized. Nasal lavage was performed in all patients before and after treatment. A panel of cytokines, including interleukin 4 (IL-4), IL-5, and IL-6, was measured by immunoassay on fluids recovered from nasal lavage. Total symptom score (including rhinorrhea, nasal itching, sneezing, and nasal obstruction) was evaluated before and after treatment.

RESULTS:

Twenty patients with perennial allergic rhinitis were evaluated (13 men and 7 women; mean age, 24.7 years). Budesonide aqueous nasal spray treatment showed a significant decrease of IL-4 (P = .007), IL-5 (P = .04), and IL-6 levels (P = .009). Budesonide aqueous nasal spray treatment also induced significant symptom relief (P = .006). Placebo treatment did not significantly affect the evaluated parameters.

CONCLUSIONS:

This study shows that budesonide aqueous nasal spray is effective in exerting immunomodulatory activity by reducing cytokine pattern and relieving symptoms. These findings are evidence of the effects of intranasal budesonide in treating perennial allergic rhinitis.
