Differential effect of omalizumab on pulmonary function in patients with allergic asthma with and without chronic rhinosinusitis

Abstract

Patients with allergic asthma who were treated with omalizumab manifested some improvement in PFT scores. CRS may add to the overall symptom burden experienced by patients with asthma, especially in those with increasing severity, but comorbid CRS did not adversely impact the therapeutic potential of omalizumab. In fact, the benefit of omalizumab was more likely to be observed in patients with asthma and with CRS than in patients with asthma and without CRS.
