The Association Between HIV/AIDS, Ototoxicity of Its Treatments, and Occupational Noise Induced Hearing Loss: A Narrative Review Mapping the Existing Literature and Identifying Research Gaps.

Hearing loss remains a significant but underexplored health challenge in individuals with HIV/AIDS, particularly those exposed to occupational noise. The ototoxic effects of antiretroviral therapy (ART) and comorbid conditions like tuberculosis (TB) further compound the risk. This narrative review examines the intersection of HIV/AIDS, ART, and occupational noise-induced hearing loss (ONIHL), emphasizing the South African and broader African contexts. The aim of the study was to map the existing literature on the association between HIV/AIDS, its treatments, and ONIHL, and to identify research gaps to inform policy and clinical practice. A narrative review approach was adopted, systematically searching databases including PubMed, Scopus, and Web of Science. Studies published between 2000 and 2024 were included, focusing on the effects of HIV/AIDS, ART, and occupational noise exposure on hearing health. Data extraction and thematic synthesis were performed to identify key findings and gaps. Twenty studies were included, covering diverse settings such as South Africa, Cameroon, Tanzania, and the USA. Three key themes emerged: (1) dual burden of HIV and occupational noise exposure: HIV-positive individuals in noise-intensive industries, such as mining, face amplified risks of hearing loss due to immunological compromise and ototoxic TB treatments; (2) ototoxicity of ART: older ART regimens, widely used in resource-limited settings, are associated with a higher prevalence of sensorineural hearing loss (SNHL); and (3) immunological susceptibility to ONIHL: HIV-related immune suppression exacerbates cochlear damage from noise and ototoxic agents, contributing to both peripheral and central auditory dysfunction. This review highlights the urgent need for integrated hearing health interventions in HIV care and occupational health frameworks, particularly in high-prevalence regions like South Africa. Routine audiological assessments, access to safer ART regimens, and enhanced workplace protections are essential to mitigate the dual burden of HIV/AIDS and ONIHL. Future research should prioritize longitudinal studies and innovative, low-cost solutions for resource-limited settings.
