Successful treatment of eosinophilic otitis media associated with severe bronchial asthma with an anti-IL-5 monoclonal antibody, mepolizumab

摘要

Eosinophilic otitis media (EOM), which is characterized by the accumulation of eosinophils in middle ear effusion and the middle ear mucosa, is a refractory type of otitis media that is often associated with asthma. Although an early diagnosis and appropriate treatment are necessary to prevent the progression of hearing loss in patients with EOM, there are currently no well-established treatments for this condition. We treated a 60-year-old male patient with asthma and EOM. The patient's asthma was poorly controlled, despite the use of high-dose inhaled corticosteroids, long acting beta-agonist treatment, and the regular use of systemic corticosteroids. Mepolizumab, an anti IL-5 monoclonal antibody, was started to treat the patient's refractory asthma. At 4 months after the initiation of mepolizumab treatment, the patient's asthma, hearing, and middle ear effusion improved. The present case suggests that mepolizumab therapy can control EOM and asthma. (C) 2018 Elsevier B.V. All rights reserved.
