Abstract

|
Autoimmune sensorineural hearing loss is a rare disease characterized by bilateral sensorineural hearing loss, some in a progressive pattern and others in idiopathic or fluctuating pattern, often accompanied by vestibular symptoms. This disease is also known as autoimmune inner ear disease (AIED), which primarily involves the vestibulo-cochlear system. However, in some cases, it occurs in the context of systemic autoimmune disorder such as wegner granulomatosis, or the Bechet disease. Response to steroids has been the requisite clinical criterion for diagnosis. Treatment usually includes corticosteroids and immunosuppressive drugs. However, after continuous steroid treatment development of corticosteroids, resistance is common in many AIED. To patients with AIED, response to steroids is not only a criterion for diagnosis but also a criterion to test steroid-sparing therapies such as methotrexate. A 10 year-old boy presenting a fluctuating pattern of bilateral sensorineural hearing loss was treated with a cytotoxic agent in suspicion of autoimmune sensorineural hearing loss. We reviewed this case with reference to relevant publications in the medical literature.
