Clinical Significance: Sensorineural hearing loss (SNHL), commonly referred to as nerve deafness, may be caused by genetic or acquired factors, such as infections, or can be immunologically mediated. A subgroup of idiopathic SNHL cases are treatable with immunosuppressive therapy. The laboratory work up to identify these cases should include serum antibody tests to 68 kD inner ear antigen. Twenty-two percent of patients with bilateral rapidly progressive SNHL and 30% of the patients with Meniere's disease had antibodies that reacted with 68 kD antigen present in the bovine inner ear extracts. Anti-68kD antibodies also occur in approximately 60% of patients with bilateral and 35% of patients with unilateral Meniere's syndrome and 37% of patients with contralateral delayed endolymphatic hydrops.
