Abstract

Objectives: The objective of our study was to review the current knowledge on Cogan's syndrome, including etiology, diagnosis and treatment. Systematic review methodology: Relevant publications on Cogan's syndrome from 1945 to 2014 were studied.

Conclusions: Cogan's syndrome is a rare autoimmune vasculitis, with unknown pathogenesis. Infection was thought to have played a role in the pathogenesis of the disease, but now the autoimmunity hypothesis is considered more likely to be true. Cogan's syndrome is characterized by ocular and audiovestibular symptoms similar to those of Meniere's syndrome. Approximately 70% of the patients have systemic disease, of which vasculitis is considered the pathological mechanism. Corticosteroids are the first line of treatment; multiple immunosuppressive drugs were also used with varying degrees of success. The novelty in the treatment of the disease is tumor necrosis factor (TNF)-alpha-blockers, but more studies are necessary to establish their efficacy.
