RT Journal Article SR Electronic T1 The APEX study: A retrospective review of responses of severe allergic asthma patients to omalizumab on continuous or non-continuous oral corticosteroids in UK clinical practice JF European Respiratory Journal JO Eur Respir J FD European Respiratory Society SP p272 VO 38 IS Suppl 55 A1 Robert Niven A1 Amr Radwan YR 2011 UL http://erj.ersjournals.com/content/38/Suppl_55/p272.abstract AB Omalizumab is an effective add-on option for patients with severe allergic asthma (who remain uncontrolled despite inhaled corticosteroid therapy), many of whom are receiving oral corticosteroids (OCS). We retrospectively reviewed records from 12 months pre- and post-omalizumab initiation in patients (age ≥12 years) with severe persistent allergic asthma who were or were not receiving continuous OCS. Percentages of patients reducing/stopping OCS use, changes in exacerbation rates, hospitalization and accident/emergency visit rates, overall responder rates and FEV1 all improved post-omalizumab (table).View this table:Responses were similar when comparing those who were and those who were not on continuous OCS at baseline. In conclusion, the benefits of omalizumab in patients not receiving continuous OCS at baseline were at least as great as those in patients receiving continuous OCS at baseline.
