ANCA関連血管炎性中耳炎の3例

抄録

Anti-neutrophil cytoplasmic antibody (ANCA)-associated vasculitis (AAV) is a form of necrotizing vasculitis that is characterized by the presence of few or no immune deposits. Recently, otological symptoms such as tinnitus, vertigo and hearing loss, not previously described to be associated with AAV, have been reported in patients with AAV. Herein, we report three cases of otitis media with ANCA-associated vasculitis (OMAAV). All three patients showed a good response to steroid therapy. Oral steroid therapy could be temporarily discontinued in the patients during the COVID-19 outbreak without recurrence of the symptoms associated with OMAAV. In conclusion, we could consider temporarily tapering the steroid dose in patients with OMAAV who show remission of the symptoms.
