Omalizumab treats chronic rhinosinusitis with nasal polyps and asthma together-a real life study.

INTRODUCTION: Chronic rhinosinusitis with nasal polyps (CRSwNP) and asthma often coexist and thus treating both with one intervention is an attractive strategy.

OBJECTIVE: To prospectively evaluate whether treatment with the monoclonal antibody against IgE Omalizumab for severe allergic asthma also effectively treats co-existent CRSwNP.

METHODS: SNOT-22 and the ACQ-7 scores were recorded at 4 and 16 weeks of treatment in a cohort of patients with both CRSwNP and severe refractory allergic asthma treated with Omalizumab (n=13) according to UK guidelines for their severe asthma. SNOT-22 in a surgery only treated CRSwNP with asthma group (n=24) was compared.

RESULTS: Rapid improvement was seen at 4 weeks and 16 weeks of treatment in both CRSwNP and asthma control. The improvement in CRSwNP with Omalizumab was similar to that seen in a group of patients who received upper airway surgery.

CONCLUSION: Omalizumab treatment for severe allergic asthma also improves co-existent CRSwNP. Further clinical studies of current and emerging biological agents for severe asthma should include upper airway outcomes. These agents may be effective for severe CRSwNP and comparative studies with surgery are warranted.
