Abstract
- BACKGROUND AND OBJECTIVE
The cysteinyl leukotrienes are bioactive lipid mediators that contribute to the pathophysiologic condition of asthma and rhinosinusitis. We tested whether the leukotriene receptor antagonist ONO-1078 (Pranukast) had steroid sparing effect on mode- rate to severe asthmatics with chronic rhinosinusitis.
METHODS
Eighteen asthmatic patients with chronic rhinosinusitis who required more than 800 mcg/day of budesonide inhalation for the adequate control of asthma symptoms were recruited for this study. For the first 4 weeks, patients were treated with high dose (800-1200 mcg/day) budesonide inhalation. For the next 4 weeks, the dose of budesonide inhalation was decreased by 400 mcg/day and oral ONO-1078 (900mg/day) was administered. FEV1 was evaluated every 2 weeks, and PC20 on methacholine challenge, serum eosinophil cationic protein and blood eosinophil count were measured every 4 weeks. Diary cards were completed with morning and evening PEFR and symptom scores for asthma and rhinosinusitis during the treatment periods.
RESULTS
Despite the reduction of the dose of inhaled corticosteroid by 400mcg/day, FEV1 and PEFR did not decrease with the addition of oral ONO-1078. The symptom scores of asthma and rhino-sinusitis did not change, and the need for beta2-agonist did not increase.
CONCLUSION
These results suggest that ONO-1078 might have steroid sparing effect in moderate to severe persistent asthmatics with chronic rhinosinusitis who required high dose nhaled budesonide to control asthma symptoms.
