Role of Interleukin 5 Inhibition in the Treatment of Eosinophilic Otitis Media
Objective Eosinophilic otitis media (EOM) is a rare form of middle ear disease characterized by a viscous effusion rich in eosinophils, a resistance to conventional treatments, and an association with bronchial asthma. The relationship between asthma and EOM suggests similarities in pathogenesis and...

Setting University of Florida Health, an academic medical center. Methods A review of 120 patients treated with benralizumab or mepolizumab was performed. Imaging evidence of otomastoiditis was used to identify 9 patients with possible EOM. Two patients were treated with benralizumab, and the remaining 7 received mepolizumab injections. Results After starting treatment, 5 patients had complete resolution of middle ear effusions (3 with mepolizumab and 2 with benralizumab); 1 had stable middle ear effusion; and 1 patient’s disease status could not be determined due to a lack of follow-up. The remaining 2 patients did not have effusions at the time when anti-IL-5 therapy was initiated, and they have not relapsed since starting treatment.
