Autoimmune inner ear disease associated with antiphospholipid antibodies

The percentage of autoimmune diseases in Western countries is approximately 8% of the total population. Despite numerous studies indicating an increase in prevalence and incidence over the past two decades, autoimmune vestibular disorders seem to be underdiagnosed, primarily due to the lack of a definitive test capable of identifying the specific antigen of the inner ear. Autoimmune inner ear disease (AIED) is defined as a rapidly progressive and often fluctuating bilateral neurosensorial hearing loss that develops over a period of weeks or months. AIED can affect only the inner ear or be part of systemic diseases such as granulomatosis with polyangiitis, Cogan's syndrome, systemic lupus erythematosus, polyarteritis nodosa, or relapsing polychondritis, among others. Our main objective was to conduct a study on the presence of antiphospholipid antibodies (aPL) in patients with AIED seen in a specialised clinic.
