Effects of mometasone furoate on the Quality of Life: a randomised placebo controlled trial in persistent allergic rhinitis and intermittent asthma using the Rhinasthma questionnaire Ilaria Baiardini1, Elisa Villa1, Anthi Rogkakou1, Sara Pellegrini1, Micaela Bacic1, Enrico Compalati1, Fulvio Braido1, Cristina Le Grazie2, Giorgio Walter Canonica1, Giovanni Passalacqua1 Clin Exp Allergy 2011

Primary outcome: Global Summary (GS) of Rhinasthma, Changes at 2 and 4 weeks versus baseline • Secondary outcomes: • Changes vs baseline in the 3 domains of Rhinasthma • Upper airways (UA) • Lower airways (LA) • Respiratory Allergy Impact (RAI) • Nasal symptom score • Nasal + asthma scores

Conclusions • Treating persistent rhinitis with mometasone furoate nasal spray resulted in a significant improvement in QoL for both upper and lower respiratory tract domains • There was a significant improvement of the global symptom scores (rhinitis + asthma) • No significant change in rhinitis symptoms when analyzed separately (trial powered on the basis of the primary outcome) • Good safety profile

CONCLUSIONS Based on the literature, SIT is effective in allergic asthma associated with rhinitis, and should be used in association with standard medications SIT reduces bronchial hyperresponsiveness, that is an indirect marker of bronchial inflammation.
