PADILHA, Monalisa Alves Dantas; MARUTA, Elaine Colombo Sousa  e  AZEVEDO, Marisa Frasson de. Occurrence of hearing disorders in infants exposed to HIV vertical transmission. Audiol., Commun. Res. [online]. 2018, vol.23, e1965.  Epub 03-Dez-2018. ISSN 2317-6431.  http://dx.doi.org/10.1590/2317-6431-2017-1965.

Purpose

To verify the occurrence of peripheral and central auditory impairments in infants exposed to HIV vertical transmission.

Methods

Retrospective analysis of 144 medical charts of infants who underwent audiological evaluation at birth, between 2010 and 2015, through transient evoked otoacoustic emissions and auditory brainstem response. The infants were divided into two groups: Study Group: composed of 72 infants with HIV positive mothers; and Control Group: with 72 infants without risk factors for hearing loss. For the study group, the results of the audiological monitoring at six months of age were also analyzed.

Results

The groups did not differ in age and sex. Results of otoacoustic emissions were normal in both groups, thus having normal cochlear function. In the study group, there was a tendency to present a higher occurrence of abnormalities in the auditory brainstem response results. The majority of infants did not show up for audiological monitoring, and among those who showed up, it was possible to identify audiological impairments.

Conclusion

There was no cochlear function impairment in the study sample. There was a tendency towards central hearing impairments in the study group, with a predominance of lower brainstem impairment. There was a poor adherence to audiological monitoring and poor agreement between the first and last evaluation.
