Abstract:

Introduction Numerous tests have been developed to help in the diagnosis of the immunomediated inner ear disease ( IMIED ) , although their usefulness is still the subject of some dispute . Material and method Studies of cohorts of patients with suspected IMIED have been reviewed . A number of different serological tests were carried out and their response to immunosuppressive therapy was noted . Results After reviewing 790 articles , the studies analyzed present great heterogeneity in the clinical characteristics of the patients recruited ( sudden deafness , fluctuating and rapidly progressive hearing loss , Menière's disease ) , the inclusion and exclusion criteria , the delay between the diagnosis and the start of medical treatment or the response criteria . Conclusions The diagnosis of IMIED is based on clinical presentation and response to corticosteroids . At present no test represents the gold standard in the diagnosis of IMIED . Serologic tests can support the diagnosis , but a methodologically more rigorous approach is needed to identify the true clinical importance of these tests for daily practice .
