Abstract:Severe asthma in elderly patients is underdiagnosed, difficult to treat, and often accompanied by atopy. This study was designed to compare clinical outcomes of omalizumab therapy in an elderly veteran population with severe allergic asthma. A retrospective, observational data analysis was performed over 2 years. Cohort outcome measures 1 year before omalizumab therapy were compared with 1 year of active treatment. Statistical analysis included two sample t-tests. The total number of patients enrolled was 17 with median age of 60 years. Omalizumab therapy was associated with a significant reduction in acute asthma exacerbations requiring prednisone treatment (p < 0.01), a significant improvement in forced expiratory volume in 1 second of 0.28 L (p < 0.01), and significantly higher Asthma Control Test (ACT) scores at 3 (p = 0.043), 6 (p = 0.039), and 12 months of therapy (p < 0.01). Two of five patients on daily prednisone for >6 months were able to discontinue systemic steroid use within 3 months of omalizumab treatment. Our study suggests elderly patients with severe atopic asthma show a significant positive clinical response to omalizumab.
