Abstract

Background: Chronic rhinosinusitis is frequently associated with asthma. A Th2 cytokine pattern has been recently reported in chronic rhinosinusitis in asthmatic children. Objective: To evaluate the effects of treating concomitant chronic rhinosinusitis on respiratory symptoms and function and immunopathological parameters in asthmatic children. Methods: Eighteen children with moderate asthma (age range, 5 to 12 years) poorly controlled by high doses of inhaled corticosteroids and chronic rhinosinusitis were evaluated for symptoms, spirometry, and inflammation at baseline, after treatment, and 1 month after suspension of treatment. All of the children were treated with a combination of amoxicillin and clavulanate (20 mg/kg twice daily) and fluticasone propionate aqueous nasal spray (100 μg/d) for 14 days. A short course of oral corticosteroids was also prescribed (deflazacort, 1 mg/kg daily for 2 days, 0.5 mg/kg daily for 4 days, and 0.25 mg/kg daily for 4 days). Rhinosinusal lavage for cytokine measurements and a nasal scraping for cytologic analysis were performed in all patients before and after medical treatment. Results: A negative endoscopy result was demonstrated in 15 children after treatment. Symptoms and respiratory function significantly improved after treatment and 1 month later; 8 children had intermittent asthma and 10 had mild asthma. A significant reduction of inflammatory cell numbers was detected in all asthmatic children. Interleukin 4 levels significantly decreased (P <0.001), whereas interferon-γ levels increased (P <0.001). Conclusion: Treatment of chronic rhinosinusitis is able to improve symptoms and respiratory function in asthmatic children, reducing inflammatory cells and reversing the cytokine pattern from a Th2 toward a Th1 profile.
