| Outline of Final Research Achievements |
ANCA (anti-neutrophil cytoplasmic antibody) -associated vasculitis is a disease that causes life threatening organ dysfunction as a result of inflammation mainly in small blood vessels of the whole body. Initial symptom is often seen in ear, nose and throat lesions such as refractory otitis media that complicates irreversible hearing loss and facial nerve paralysis and necrotizing lesions of the nasal mucosa that leads to saddle nose (low nose). However, in the early stage, ANCA which is useful for diagnosis is negative and it is often difficult to diagnose. In this study, we developed and proposed an algorithm of the examination method for early diagnosis of this disease using various ANCA measurement methods. In order to clarify the pathology of the disease, a study was conducted to prove the involvement of bacterial infection in the middle ear, which triggers the onset of the disease.
