Abstract
Purpose The study investigated whether the auditory brainstem response (ABR) at a baseline and at higher repetition rates can detect if neurodegeneration has occurred in adults living with HIV who present with normal behavioral pure-tone thresholds. Method An exploratory research design was used. Forty adults with HIV (80 ears, 57.5% female; M age = 26.3 years, SD = 3.68) and 20 adults without HIV participated. Phase 1 compared ABR absolute and interwave latencies at a baseline rate. Phase 2 examined the effect of HIV status and category of immunodeficiency on ABR absolute Wave V latency and Wave V latency shift at increased stimulus rates. Analysis included a two-way analysis of variance of the interaction between stimulus rate and HIV status and between CD4+ category and rate, and multiple regression analysis. Results In adults living with HIV, the baseline ABR yielded prolonged Wave III and V absolute latencies and interpeak prolongations in 22.5%. Interaural Wave V latency differences were present in 15% of participants. An additional 15% of ears presented with abnormal Wave V at increased rates. No significant interaction between HIV status and rate in either ear or between CD4+ category and rate was found in either ear (p > .05). Although rate and gender contributed significantly to the prediction of Wave V latency of the rate study (left and right, p < .001), HIV status did not (left and right, p > .05). Conclusions Although the interaction of HIV status and CD4+ with rate was not significant, more ears were identified with abnormal results at increased stimulus rates than with the baseline ABR alone. The ABR at increased rates may therefore be a valuable addition for the identification of individuals living with HIV with auditory neural deficiencies.

Abstract
OBJECTIVE To analyze the results of the audiological evaluation of children with HIV and AIDS. DATA COLLECTION Systematic review carried out in May 2019 in the Web of Science, PubMed, SciELO, and Scopus databases. Case reports and original articles were included, with no limitationsregarding country or year of publication. DATA SYNTHESIS 278 articles were identified; 26 were included, in which HIV/AIDS was shown to be a risk factor for hearing loss (OR=5.364; p=0.00). The studies used different audiological exams, with varying methodologies. There was no difference regarding the type of hearing loss (p=0.119). CONCLUSION Longitudinal studies using the same type of examination at all stages are suggested, to allow better monitoring of the effects of HIV on the child's hearing,and studies that provide more methodological details. The knowledge of the influence of HIV on the child's auditory system may lead to the promotion of measures that minimize the prevalence of hearing loss, allow an early diagnosis and timely rehabilitation, so as not to compromise child development.

Abstract
INTRODUCTION Antiretroviral therapy (ART) has had a major impact on life expectancy from HIV as many people now live with it as a chronic disease. Chronic HIV has been associated with a range of comorbid disabilities and health conditions, one of which is hearing loss. Undiagnosed and untreated hearing loss, particularly in children, has been linked to poorer spoken language skills, with subsequent effects on academic performance. METHODS This systematic scoping review aimed to summarize the available peer-reviewed literature on hearing loss in HIV-infected children, specifically to describe its extent and nature. The review followed the framework proposed by Arksey and O'Malley. Key search terms included hearing loss (and synonyms), child (and synonyms), and HIV. Electronic databases (EBSCOhost Research Platform, PubMed, Web of Science and Scopus databases) were searched for any relevant articles published from January 1, 2000 to June 30, 2019. Reference lists of included articles were pearled for additional relevant articles not already identified. Each stage of the selection process was conducted independently by two authors. The results were then collated by a third author who also resolved any discrepancies. Extracted data included sample descriptors, audiologic tests, hearing loss prevalence, hearing loss descripts, and factors associated with hearing loss. RESULTS Seventeen articles were included; 10 from Africa, four from South America, two from North America and the remaining article from Asia. Although most of the articles reported on pure tone audiometry, the samples as well as the cut-off criteria for normal hearing were heterogenous. Prevalence of hearing loss varied across articles (from 6% to 84%). Conductive hearing loss occurred more frequently than sensorineural or mixed hearing loss. ART use and ear infection were reported as significant in three of five articles that reported on significant associates of HIV-related hearing loss. CONCLUSION There was a modest volume of research from a limited number of countries. Heterogeneity in sampling and audiometric methods precluded a clear understanding of potential associations between chronic HIV-related hearing loss and contributing factors.

SOUTH AFRICAN JOURNAL OF COMMUNICATION DISORDERS 2020; 67:e1-e9.

Abstract
Background Recent estimates reveal that there are approximately 280 000 children between the ages of birth and 14 years who are living with the human immunodeficiency virus (HIV) and acquired immunodeficiency syndrome (AIDS) in South Africa. These children are living with a compromised immune system, are vulnerable to opportunistic infections and subsequent hearing loss. However, there is limited research on the nature and extent of this sensory impairment amongst school-aged children. Objective This study aimed to determine an audiological profile of a cohort of school-aged children attending an antiretroviral (ARV) clinic, describing the occurrence of hearing loss and nature in terms of degree, type, configuration and symmetry. Methods A non-experimental descriptive exploratory study was conducted, where 30 children aged between 6 and 12 years underwent diagnostic audiological assessments. Audiological procedures included case history, medical record review, otoscopic examination, immittance audiometry, pure-tone audiometry, speech audiometry, distortion product otoacoustic emissions (DPOAEs) and neurological auditory brainstem response (ABR) testing. The results were analysed descriptively using SPSS version 22 software. Results The results indicated abnormal otoscopic findings in half the participants, and consequently type C tympanograms were the most common. Of the 28 participants who could be assessed with pure-tone audiometry, 15 (54%) showed a hearing loss. A bilateral rising mild, conductive hearing loss was predominant. Thirteen (43%) of the participants could not be tested using DPOAE because of outer and middle-ear pathology. Neurological ABR testing revealed an abnormality in 18 (60%) of the participants suggesting the sensitivity of the ABR to detect subtle neurological changes. Conclusion Half the children in this study showed hearing loss, which has serious implications for the holistic management of the children within the health and educational contexts. Therefore, there is a need for audiological monitoring of children with HIV and AIDS. Keywords audiological profile; HIV; AIDS; hearing loss; school children.

Abstract
Abstract: Purpose: to determine the functioning of the efferent auditory system in premature newborns with intraventricular hemorrhage. Method: the sample consisted of 44 newborns, divided into two groups. The study group was composed of 22 premature newborns with intraventricular hemorrhage/and the control group was composed of 22 newborns without intraventricular hemorrhage, matched to the study group for gestational age, correct gestational age and sex. The groups were submitted to the evaluation of the inhibitory effect of auditory efferent in otoacoustic emissions (equipment ILOv6-Otodynamics Ltda®) and auditory evoked potential with and without contralateral noise (equipment SmartEP-Intelligent Hearing Systems®). Results: newborns with intraventricular hemorrhage exhibited a higher occurrence of central hearing alteration as well as a lesser occurrence of the inhibitory effect of auditory efferent in otoacoustic emissions and auditory evoked potential compared to the newborns without this condition. An association was found between central hearing alteration and a lower occurrence of inhibitory effect. Agreement was found between the inhibitory effect test on otoacoustic emissions and latency of the auditory evoked potential. Conclusion: premature newborns with intraventricular hemorrhage have a greater occurrence of functional abnormality of the afferent auditory system, which can be effectively identified through an evaluation of the inhibitory effect of auditory efferent in otoacoustic emissions evoked by a transient stimulus and latency parameter in the brainstem auditory evoked potential.

Abstract
Introduction Auditory processing disorders can negatively affect academic performance in children. They can result from a number of aetiologies, including the human immunodeficiency virus (HIV). Although studies in paediatrics are limited, research suggests that HIV-infected children display poorer auditory processing skills than uninfected children. Methods The aims of this study were to scan the peer-reviewed literature on auditory processing skills in HIV-infected children, to describe how auditory processing was tested, how auditory processing skills were reported, and to identify gaps in current evidence. This systematic scoping review was conducted using a modified version of Arksey and O’Malley’s framework. Key words comprised ‘HIV’, ‘auditory processing’, ‘hearing’ and ‘child’. Electronic databases were searched for relevant articles published from 1 January 2000 to 30 April 2018, and reference lists of included studies were pearled. Two researchers reviewed the articles and extracted data on sample descriptors, auditory processing testing procedures, and auditory processing skills. A third author collated the results and resolved discrepancies. The American Speech-Language-Hearing Association description of auditory processing skills framed the analysis. Results Five articles were included in this review (three from Brazil, one each from Mexico and Tanzania). Samples, and methods of testing were heterogeneous. Three studies reported on localization abilities, while gap detection thresholds, performance on dichotic tasks and speech discrimination scores were reported in one article each. No one study tested all areas of auditory processing skills and there was limited information about the auditory processing skills required for learning. Conclusion This review highlighted the current sparse evidence-base for auditory processing in HIV-infected children. It identified the need to standardise testing procedures, measures of auditory processing skills, and sample selection.

Abstract
Introduction Possible associations between Zika virus infection and hearing loss were observed during the epidemic in the Americas. Objective To describe the auditory alterations, pathogenesis and recommendations for follow-up in individuals with prenatal or acquired Zika virus infection. Methods Bibliographic research conducted in March/2018–April/2019 at the main available databases. Article selection, data extraction and quality evaluation were carried out by two independent reviewers. Studies containing auditory evaluation of patients with congenital or acquired Zika virus infection; and/or hypotheses or evidences on the pathophysiology of auditory impairment associated with Zika virus; and/or recommendations on screening and follow-up of patients with auditory impairment by Zika virus were included. Results A total of 27 articles were selected. Sensorineural and transient hearing loss were reported in six adults with acquired Zika virus infection. Of the 962 studied children, 482 had microcephaly and 145 had diagnostic confirmation of Zika virus; 515 of the 624 children with auditory evaluation performed only screening tests with otoacoustic emissions testing and/or automated click-stimuli auditory brainstem response testing. Studies in prenatally exposed children were very heterogeneous and great variations in the frequency of altered otoacoustic emissions and automated click-stimuli auditory brainstem response occurred across the studies. Altered otoacoustic emissions varied from 0% to 75%, while altered automated click-stimuli auditory brainstem response varied from 0% to 29.2%. Sensorineural, retrocochlear or central origin impairment could not be ruled out. One study with infected mice found no microscopic damage to cochlear hair cells. Studies on the pathogenesis of auditory changes in humans are limited to hypotheses and recommendations still include points of controversy. Conclusion The available data are still insufficient to understand the full spectrum of the involvement of the auditory organs by Zika virus, the pathogenesis of this involvement or even to confirm the causal association between auditory involvement and virus infection. The screening and follow-up recommendations still present points of controversy.

Abstract
OBJECTIVES To systematically review evidence on the prevalence and characteristics of hearing impairment among children and adults living with HIV in low- and middle-income countries (LMIC). METHODS Articles were identified up to January 2016 through searching four electronic databases. Epidemiological studies conducted in LMIC that explored the association between HIV status and hearing loss, with or without an HIV-uninfected comparison group, were eligible for inclusion. Results were screened and assessed for eligibility, and data were extracted by two reviewers, with discussion in the case of disagreement. Findings were narratively synthesised. RESULTS The search identified 638 unique references, of which 21 studies were included in the review, including 3491 people with HIV from 13 LMIC. There was lack of consistency in the definition used for hearing loss, making comparability across studies difficult. Among children with HIV, across the three studies that used a cut-off of >15 dB in either ear, the prevalence of hearing loss ranged from 22 to 37%. Among the three studies that used >25 dB in either ear, the prevalence ranged from 32 to 39%. Among adults with HIV, for the five studies that used a threshold of >25 dB for either ear, the prevalence ranged from 10 to 43%. The prevalence of hearing impairment was significantly higher among people with HIV than in controls in eight of the ten studies that assessed this comparison. Conductive hearing loss was the most common type of hearing loss in children with HIV, while sensorineural hearing loss was more common in adults with HIV. There was a lack of evidence for an association between ART use and hearing loss, although there was some suggestion that late stage of HIV disease or low CD4 count was related to hearing loss. There were concerns about the quality of the studies included in the review. CONCLUSIONS The current evidence is suggestive of a high prevalence of hearing loss among people living with HIV compared to people without HIV, or to WHO estimates for the general population. More research is needed to better understand the aetiology of hearing loss in relation to HIV, and whether screening for and treatment of hearing loss can be effectively integrated into HIV treatment services needs further research.

Abstract
INTRODUCTION Pediatric HIV infection and treatment may increase the risk for hearing loss (HL), both sensorineural (SNHL) and conductive hearing loss (CHL). There is limited data on this subject, especially from sub Saharan Africa. The aim of this study was therefore to compare the prevalence of hearing loss among HIV positive and negative children, to determine the types of hearing loss and whether Nevirapine (NVP) based antiretroviral therapy (ART) is associated with HL. METHODS We conducted a cross sectional study at two tertiary health facilities in south western Uganda. We consecutively enrolled 79 HIV negative and 148 HIV positive children aged between 6 and 12 years. Inclusion criteria were completion of written consent, ability to follow instructions to perform an audiogram and absence of congenital HL. We conducted hearing screening using the iPad Shoebox® audiometer, and confirmatory assessments were conducted using pure tone audiometry. Hearing was classified as either normal hearing, CHL, SNHL or mixed. RESULTS Of the 227 children enrolled, 115 (50.7%) were female. The mean age was 9.2 years (median = 9). Based on self-report, frequency of HL among HIV positive children was 6.8% and 20.3% among HIV negative children (p=<0.01). Using objective measures, prevalence of HL among the HIV positive children was 8.8% compared to 10.1% among the HIV negative children (p = 0.74). CHL was generally more frequent than SNHL but SNHL occurred more frequently among HIV positive (7.4%) compared to HIV negative children (3.8%). No association was found between NVP based ART and HL (p = 0.41). Logistic regression showed that older age of the child (p = 0.01), previous ear infection (p=<0.01), tuberculosis (TB) treatment (p=<0.01) and long term duration on ART (p=<0.01) were significantly associated with HL. Age (p = 0.02), previous ear infection (p = 0.01) and TB treatment (p = 0.005) remained significant in the multiple regression model. CONCLUSION Prevalence of HL is similar among HIV positive and negative children. Older age of the child, previous ear infection, use of TB drugs and long duration on ART among the HIV positive children increase the odds of having hearing loss among children. However, use of NVP was not associated with HL.

Abstract
INTRODUCTION With improved access to antiretroviral therapy (ART), HIV infection is becoming a chronic illness. Preliminary data suggest that HIV-infected children have a higher risk of disabilities, including hearing impairment, although data are sparse. This study aimed to estimate the prevalence and types of hearing loss in HIV-infected children in Lilongwe, Malawi. METHODS This was a cross-sectional survey of 380 HIV-infected children aged 4-14 years attending ART clinic in Lilongwe between December 2013-March 2014. Data was collected through pediatric quality of life and sociodemographic questionnaires, electronic medical record review, and detailed audiologic testing. Hearing loss was defined as >20 decibels hearing level (dBHL) in either ear. Predictors of hearing loss were explored by regression analysis generating age- and sex-adjusted odds ratios. Children with significant hearing loss were fitted with hearing aids. RESULTS Of 380 patients, 24% had hearing loss: 82% conductive, 14% sensorineural, and 4% mixed. Twenty-one patients (23% of those with hearing loss) were referred for hearing aid fitting. There was a higher prevalence of hearing loss in children with history of frequent ear infections (OR 7.4, 4.2-13.0) and ear drainage (OR 6.4, 3.6-11.6). Hearing loss was linked to history of WHO Stage 3 (OR 2.4, 1.2-4.5) or Stage 4 (OR 6.4, 2.7-15.2) and history of malnutrition (OR 2.1, 1.3-3.5), but not to duration of ART or CD4. Only 40% of caregivers accurately perceived their child's hearing loss. Children with hearing impairment were less likely to attend school and had poorer emotional (p = 0.02) and school functioning (p = 0.04). CONCLUSIONS There is an urgent need for improved screening tools, identification and treatment of hearing problems in HIV-infected children, as hearing loss was common in this group and affected school functioning and quality of life. Clear strategies were identified for prevention and treatment, since most hearing loss was conductive in nature, likely due to frequent ear infections, and many children with hearing loss qualified for hearing aids. Screening strategies need to be developed and tested since caregivers were not reliable at identifying hearing loss, and often mis-identified children with normal hearing as having hearing loss. Children with frequent ear infections, ear drainage, TB, severe HIV disease, or low BMI should receive more frequent ear assessments and hearing evaluations.

Abstract
OBJECTIVES Abnormal hearing tests have been noted in human immunodeficiency virus (HIV)-infected patients in several studies, but the nature of the hearing deficit has not been clearly defined. The authors performed a cross-sectional study of both HIV+ and HIV- individuals in Tanzania by using an audiological test battery. The authors hypothesized that HIV+ adults would have a higher prevalence of abnormal central and peripheral hearing test results compared with HIV- controls. In addition, they anticipated that the prevalence of abnormal hearing assessments would increase with antiretroviral therapy (ART) use and treatment for tuberculosis (TB). DESIGN Pure-tone thresholds, distortion product otoacoustic emissions (DPOAEs), tympanometry, and a gap-detection test were performed using a laptop-based hearing testing system on 751 subjects (100 HIV- in the United States, plus 651 in Dar es Salaam, Tanzania, including 449 HIV+ [130 ART- and 319 ART+], and 202 HIV-, subjects. No U.S. subjects had a history of TB treatment. In Tanzania, 204 of the HIV+ and 23 of the HIV- subjects had a history of TB treatment. Subjects completed a video and audio questionnaire about their hearing, as well as a health history questionnaire. RESULTS HIV+ subjects had reduced DPOAE levels compared with HIV- subjects, but their hearing thresholds, tympanometry results, and gap-detection thresholds were similar. Within the HIV+ group, those on ART reported significantly greater difficulties understanding speech in noise, and were significantly more likely to report that they had difficulty understanding speech than the ART- group. The ART+ group had a significantly higher mean gap-detection threshold compared with the ART- group. No effects of TB treatment were seen. CONCLUSIONS The fact that the ART+/ART- groups did not differ in measures of peripheral hearing ability (DPOAEs, thresholds), or middle ear measures (tympanometry), but that the ART+ group had significantly more trouble understanding speech and had higher gap-detection thresholds indicates a central processing deficit. These data suggest that: (1) hearing deficits in HIV+ individuals could be a CNS side effect of HIV infection, (2) certain ART regimens might produce CNS side effects that manifest themselves as hearing difficulties, and/or (3) some ART regimens may treat CNS HIV inadequately, perhaps due to insufficient CNS drug levels, which is reflected as a central hearing deficit. Monitoring of central hearing parameters could be used to track central effects of either HIV or ART.

Abstract
OBJECTIVE To characterize the findings of behavioral hearing assessment in HIV-positive individuals who received and did not receive antiretroviral treatment. METHODS This research was a cross-sectional study. The participants were 45 HIV-positive individuals (18 not exposed and 27 exposed to antiretroviral treatment) and 30 control-group individuals. All subjects completed an audiological evaluation through pure-tone audiometry, speech audiometry, and high-frequency audiometry. RESULTS The hearing thresholds obtained by pure-tone audiometry were different between groups. The group that had received antiretroviral treatment had higher thresholds for the frequencies ranging from 250 to 3000 Hz compared with the control group and the group not exposed to treatment. In the range of frequencies from 4000 through 8000 Hz, the HIV-positive groups presented with higher thresholds than did the control group. The hearing thresholds determined by high-frequency audiometry were different between groups, with higher thresholds in the HIV-positive groups. CONCLUSION HIV-positive individuals presented poorer results in pure-tone and high-frequency audiometry, suggesting impairment of the peripheral auditory pathway. Individuals who received antiretroviral treatment presented poorer results on both tests compared with individuals not exposed to antiretroviral treatment.

Abstract
Objetivo Avaliar a audição de crianças com HIV/AIDS e analisar os resultados dessa avaliação, associando-os à faixa etária e ao tempo de diagnóstico. Métodos Caracteriza-se por ser um estudo descritivo e transversal. Foram incluídas 23 crianças com HIV/AIDS, em acompanhamento em dois serviços de atendimento especializado (SAE), em João Pessoa (PB). As crianças foram submetidas à avaliação audiológica básica (audiometria e imitanciometria) e os achados foram analisados com o uso de estatística descritiva. Resultados No exame audiométrico, observou-se 39 orelhas alteradas, apresentando maior ocorrência para perda discreta. Na avaliação imitanciométrica, predominou a curva do tipo B, seguida da curva A, As e C, respectivamente. Ao associar os tipos de perdas auditivas à faixa etária e ao tempo de diagnóstico do HIV, obteve-se diferença (p<0,001) para ambas as variáveis. Conclusão Crianças portadoras de HIV/AIDS apresentam perda auditiva e existe associação com a idade e com o tempo de infecção. Evidencia-se a necessidade de realizar um trabalho educativo junto aos familiares e à própria criança com HIV, acerca de medidas que podem ser adotadas para preservar, ao máximo, a saúde auditiva.

Abstract
PURPOSE: To investigate the occurrence of hearing loss in children with HIV and its association with viral load, opportunistic diseases, and antiretroviral treatment. METHODS: A cross-sectional study was carried out with 23 HIV-positive children under care at two specialized centers in João Pessoa, Paraíba, Brazil. Their parents or legal guardians responded to a questionnaire, containing data on the clinical situation and the hearing health of the children, who were then submitted to audiological assessment. We complied with the guidelines for human research contained in the CNE (National Education Council) Resolution number 196/1996. The findings were analyzed through descriptive statistics. RESULTS: We observed that lamivudine (3TC) was the antiretroviral drug most used in 17 (94.4%) patients, followed by Kaletra (KAL), administered in 14 (77.8%) patients, d4T in 11 (61.1%) patients, and zidovudine (AZT) in 7 (38.9%) participants. Otitis was the most frequent opportunistic disease, with 11 (61.1%) cases. In the audiometric examination, we observed 39 (84.8%) ears with hearing loss and 7 (15.2%) normal ears. After the immitance testing, we found five (10.9%) normal ears, characterized by type A tympanometric curves. The other 41 (89.1%) ears were revealed as altered, with predominance of type B curves in 67.4% of the cases. CONCLUSION: There were hearing alterations in children with HIV/AIDS analyzed in this study. Discreet hearing losses were the most occurring. We verified statistically significant associations with the use of antiretroviral therapy and otitis. Therefore, we point out the importance of auditory monitoring and intervention as soon as possible, thus favoring adequate development in language and decreasing possible difficulties in learning and social inclusion.

Abstract
PURPOSE: To investigate the occurrence of hearing loss in individuals with HIV/AIDS and their characterization regarding type and degree. RESEARCH STRATEGY: It was conducted a systematic review of the literature found on the electronic databases PubMed, EMBASE, ADOLEC, IBECS, Web of Science, Scopus, Lilacs and SciELO. SELECTION CRITERIA: The search strategy was directed by a specific question: "Is hearing loss part of the framework of HIV/AIDS manifestations?", and the selection criteria of the studies involved coherence with the proposed theme, evidence levels 1, 2 or 3, and language (Portuguese, English and Spanish). DATA ANALYSIS: We found 698 studies. After an analysis of the title and abstract, 91 were selected for full reading. Out of these, 38 met the proposed criteria and were included on the review. RESULTS: The studies reported presence of conductive, sensorineural, and mixed hearing loss, of variable degrees and audiometric configurations, in addition to tinnitus and vestibular disorders. The etiology can be attributed to opportunistic infections, ototoxic drugs or to the action of virus itself. The auditory evoked potentials have been used as markers of neurological alterations, even in patients with normal hearing. CONCLUSION: HIV/AIDS patients may present hearing loss. Thus, programs for prevention and treatment of AIDS must involve actions aimed at auditory health.
