LETTER TO THE EDITORS
Dear Editor, the publication on “Auditory-perceptual and acoustic analysis of voices of HIV-infected children” is very interesting(11 Pereira EC, Rodrigues CO, Silvério KCA, Madazio G, Behlau M. Auditory-perceptual and acoustic analysis of voices of HIV-infected children. CoDAS. 2017;29(6):e20170022. http://dx.doi.org/10.1590/2317-1782/201720170022. PMid:29236906.
http://dx.doi.org/10.1590/2317-1782/2017...
). Pereira et al. concluded that “HIV-infected children presented similar vocal quality to children without the illness, both for the perceptual-auditory and acoustic evaluation”(11 Pereira EC, Rodrigues CO, Silvério KCA, Madazio G, Behlau M. Auditory-perceptual and acoustic analysis of voices of HIV-infected children. CoDAS. 2017;29(6):e20170022. http://dx.doi.org/10.1590/2317-1782/201720170022. PMid:29236906.
http://dx.doi.org/10.1590/2317-1782/2017...
). In fact, the vocal quality of children should not be different regardless of HIV infected status. Nevertheless, the HIV infected children with poor immune status are usually superimposed with opportunistic medical disorders which might affect the vocal quality. In HIV infected cases with severe immunodeficient status, there might be an abnormal laryngeal electromyography and poor vocal quality(22 Sims HS, Patel S, Barr A. Laryngeal electromyography findings in a patient with HIV, John Cunningham virus and bilateral true vocal fold motion impairment. J Natl Med Assoc. 2008;100(7):856-8. http://dx.doi.org/10.1016/S0027-9684(15)31381-X. PMid:18672564.

). The CMV infection, which is a common opportunistic infection in HIV infected patients with late stages of disease, is a possible important cause of poor vocal quality(33 De la Blanchardiere A, Dore M, Salmon D, Sicard D. Left vocal cord paralysis in cytomegalovirus multifocal neuropathy in a patient with HIV infection. Presse Med. 1996;25(3):106-7. PMid:8746083.). In the present report by Pereira et al., if there is additional classification of immune status of the HIV infected children, there might be some difference in subgroup analysis.
