RESUMO
A surdez neurossensorial (SNS) imunomediada é uma das formas de SNS com possibilidade de reversão. Surdez súbita, surdez rapidamente progressiva e doença de Ménière são relacionadas à etiologia autoimune. O Western blot (WB) com antígeno de tecidos bovinos é usado para detecção do anticorpo anti-68kD (hsp70) em SNS imunomediada. Marcadores específicos são necessários para diagnóstico e prognóstico desta entidade. O objetivo do estudo foi determinar reatividade dos soros de pacientes com SNS contra antígeno de células humanas (HeLa) pelo WB. Observou-se reatividade contra células HeLa, confirmando a presença de autorreatividade e autoanticorpos. O papel destes anticorpos ainda é desconhecido. /Immune-mediated sensorineural hearing loss (SNHL) is one of few forms of reversible SNHL. The rapidly progressive hearing loss, sudden SNHL and Ménière’s disease are often related to autoimmune etiology. Western blot with bovine tissues as target has been used, detecting anti-68kD antibody (hsp70) in immune-mediated SNHL. Other specific markers are necessary to diagnosis and prognosis. The aim of this study was determinate reactivity from SNHL patients’ sera against human cell line antigen (HeLa) by Western blot. Reactivity to HeLa cells was observed reinforcing autoreactivity and autoantibody presence. The role of these autoantibodies is unknown and futher studies are necessary...
