    Abstract:
    Autoimmune inner ear disease was first described by McCabe in 1979. The diagnosis is supported by cell-mediated immune responses to inner ear membrane antigen stimulation. Cogan's syndrome consists of vestibuloauditory dysfunction, ocular inflammation, and nonreactive serologic tests for syphilis. The ocular disease can be controlled by steroids; unfortunately, some patients ultimately become totally deaf. An autoimmune etiology has long been suspected but only recently confirmed by McCabe. In our study two patients with Cogan's syndrome were studied for autoimmune inner ear disease with the use of both cellular and humoral immune tests. Results were compared to normal control subjects. On the basis of test results, preliminary conclusions were that (1) the vestibuloauditory symptoms of Cogan's syndrome are autoimmune in origin; (2) the autoimmune process is mediated through cellular rather than humoral (antibody) pathways; (3) systemic steroids may suppress positive test results; and (4) test results are more likely to be positive when symptoms are acute. Therapeutic implications are significant: the addition of cytotoxic drugs to steroids in selected cases may help prevent total deafness that otherwise might be inevitable.
