Successful Infliximab Treatment in Cogan Syndrome With Cardiac Complications

Cogan's syndrome (CS) is a rare chronic autoimmune vasculitis that can have significant systemic consequences and progress with progressive and inflammatory eye (interstitial keratitis, scleritis, episcleritis, uveitis) and audiovestibular (sensorineural hearing loss, vertigo, tinnitus) involvement.Vasculitis is observed in approximately 15% of patients with CS and may present as aortitis, large-vessel vasculitis (Takayasu-like), moderate arteritis, or other vasculitic syndromes.In this case report, we present the development of severe aortic and mitral valve insufficiency in a patient diagnosed with CS who was admitted to the hospital with episcleritis and sensorineural hearing loss.
