    Hearing Disorders in HIV Positive Adult Patients
    (East and Central African Journal of Surgery, 2010) Ongulo, B. A.; Oburra, H. O.
    Background: This study was aimed at determining the prevalence and type of hearing disorders in HIV positive patients and any correlationship with the CD4 counts/stage of HIV/AIDS in patients attending the comprehensive care clinic (CCC). Methods: Case control study of 194 HIV positive patients attending CCC recruited into the study after informed consent. A thorough clinical examination and otoscopy done followed by tuning fork tests, Pure Tone Audiometry and tympanometric tests. This was compared with 124HIV negative subjects matched for age and sex who were recruited from the voluntary counseling and testing centre. The world health organization staging of the HIV/AIDS disease and the CD4 positive lymphocyte cell count were carried out and correlated with any hearing disorder. Results were analyzed using statistical package for social sciences version 10.0. Results: Hearing loss (HL) was present in 33.5% of HIV positive compared to 8.1% in negative subjects. No gender bias in HL but HL worsened with advancement of age. SNHL was the most common and the higher frequencies were the most affected. Low CD4 cell count and advanced HIV disease were associated with increased chance of having a hearing loss. Conclusion: Hearing loss is more prevalent in HIV positive individuals than negative normal subjects and tends to worsen with the advancement of the HIV disease. This may negatively impact on the overall care and standard of living of HIV positive patients, hence otological care should be part of the comprehensive care.

    Hearing disorders in HIV positive adult patients not on anti-retroviral drugs at Kenyatta National Hospital
    (East African Medical Journal, 2010-09) Ongulo, B. A.; Oburra, H. O.
    Objectives: To determine the prevalence and type of hearing disorders in HIV positive patients not on anti - retroviral drugs (ARVs) and correlate this with the world health Organization (WHO) stage of HIV disease and CD4 positive cell counts. Design: Case control study. Setting: comprehensive care clinic (CCC) and voluntary counseling and testing centre at Kenyatta National Hospital. Subjects: One hundread and ninety four HIV positive patients attending CCC and 124 HIV negative subjects recruited from voluntary counseling and testing (VCT) centre. Results: Hearing loss (HL) was present in 33.5% of HIV positive compared to 8.1% in negative subjects. No gender bias in HL Sensorineural hearing loss (SNHL) was the most common and the frequencies most ‘affected were four and eight kHz Conclusion: Hearing loss is more prevalent in HIV positive individuals not on anti - retroviral drugs than negative normal subjects. Low CD4 cell count and advanced HIV diseases were associated with increased chance of having a hearing loss. Otological care should be part of the comprehensive care of HIV positive patients.
