Other infections/diseases, including Wegeners Granulomatosis and Rheumatoid Arthritis need to be excluded. Approximately 70% of the patients have systemic disease, of which vasculitis is considered the pathological mechanism. Recent work has suggested that high-resolution MRI and antibodies to inner ear antigens may be helpful. Physical examination can show a degree of ataxia and spontaneous nystagmus [7]. Prednisone, methotrexate, and eventually, Rituxan infusions allowed me to finally put it into remission. Although any age can be affected the syndrome is commonest in young adults (20s and 30s). Infliximab seems to be effective in inducing and maintaining remission in patients with therapy resistant Cogans syndrome [2, 27].

[1] Infliximab is now commonly used along with corticosteroids, especially in those who have failed combinations of steroids and DMARD therapy. If these medications do not work well enough, oral antibiotics, such as doxycycline (sold under many brand names), may be recommended in case an infection is causing the eye inflammation. Other studies have shown that up to 70% (63% of the cases of Yamanishi [20]) of the patients with Cogans syndrome have underlying systemic disease in addition to ocular and audiovestibular dysfunctions. The audiovestibular manifestations are very similar to those of recurrent Menieres disease: abrupt onset including vertigo, nausea, instability, vomiting and tinnitus; the vestibular manifestations are secondarily associated with progressive hearing loss, leading to deafness in a period of 1- to 3-months [15,23]. Polyarteritis nodosacan be very serious if it's not treated. [1] Cogan syndrome is a diagnosis of exclusion and if interstitial keratitis is detected, syphilis, herpes, chlamydia, tuberculosis, rubeola, mumps, Lyme disease, and parasitic etiologies must be ruled out before determining Cogan syndrome as the main cause for interstitial keratitis.

Vasculitis is the name of a group of conditions that cause inflammation of the blood vessels. However, one theory is that it is an autoimmune disorder in which the body's immune system mistakenly attacks tissue in the eye and ear.
