Manifesta??es eletrofisiológicas em adultos com HIV/AIDS submetidos e n?o-submetidos à terapia anti-retroviralDOI: 10.1590/S0104-56872010000200007 Keywords: hiv, antiretroviral therapy, highly active, hearing, evoked potentials, auditory. Abstract: background: auditory evoked potentials (aep) assess the neuroelectric activity on the auditory pathway -from the auditory nerve to the cerebral cortex - in response to an acoustic stimulus or event. studies have demonstrated electrophysiological abnormalities in individuals with hiv/aids. aim: to characterize the hearing electrophysiological manifestations in adults with hiv/aids by comparing the results obtained in the group exposed to antiretroviral therapy with those obtained in the group not exposed to such treatment. method: electrophysiological evaluation of hearing (auditory brainstem response - abr, auditory middle latency reponse - amlr and p300) was conducted in 56 individuals with hiv/aids: 24 participants composed group i (not exposed to antiretroviral treatment) and 32 participants composed group ii (exposed to treatment). results: alterations in every aep were observed in individuals with hiv/ aids, especially in the abr. indeed, the group exposed to antiretroviral treatment presented more alterations. conclusion: individuals with hiv/aids may present alterations on the central and peripheral auditory nervous system. the group exposed to antiretroviral therapy presents more alterations on the brainstem auditory pathway.
