A multicenter approach to evaluate omalizumab effectiveness in Samter's triad

Omalizumab proved to be very effective in improving control of severe atopic asthma. Many small-sized studies suggested a potential role for omalizumab in the management of aspirin-exacerbated respiratory disease. The aim of this study is to describe the effectiveness of omalizumab in a multicentre group of patients with Samter's triad. We retrospectively enrolled eight patients (5 females) with Samter's triad who underwent at least one year of omalizumab therapy. Clinical data, functional parameters and questionnaires for asthma and nasal polyposis control were collected at baseline and follow-up. We observed a significant reduction of moderate-to-severe asthma exacerbations, together with an increase of FEV1 and a reduction of steroids intake. An improvement in asthma control and nasal symptoms was also reported. This multicenter study confirms the effectiveness of omalizumab in patients affected by Samter's triad. Omalizumab may represent a potential therapeutic option for the management of this disease.
