AbstractBACKGROUND: Patients with asthma who have persistent symptoms despite treatment with inhaled steroids and long-acting beta agonists are considered to have severe asthma. Omalizumab is a monoclonal antibody directed against IgE, which is used as an add-on treatment for patients who have severe persistent allergic asthma. AIMS: The aim of this study was to assess the clinical benefit and healthcare utilisation of patients who responded to omalizumab therapy and to establish an overall cost implication. METHODS: This was an observational retrospective cohort study designed to investigate the effect of omalizumab on exacerbations of asthma before and after 6 months of treatment in Irish patients. RESULTS: Centres who had treated patients with severe allergic asthma for the 6 months prior and post omalizumab treatment were audited with a standardised assessment tool. Sixty-three (32 male) patients were studied. In the 6 months prior to omalizumab 41 of 63 (66%) had been hospitalised, and this fell to 15 of 63 (24%), p < 0.0001 in the 6 months after treatment was started. Hospital admissions reduced from 2.4 +/- 0.41 to 0.8 +/- 0.37 and the mean number of bed days occupied was reduced from 16.6 +/- 2.94 to 5.3 +/- 2.57 days, p < 0.001. The number of oral corticosteroid doses used fell from 3.1 +/- 0.27 to 1.2 +/- 0.17, p < 0.001. The overall cost saving per omalizumab responder patients for 6 months was 834. CONCLUSIONS: Six months therapy with omalizumab reduced the number of bed days, the number of hospitalisations and the use of oral corticosteroids compared to the 6 months prior to commencement. Despite the cost of the additional therapy there were overall savings in health costs.
