    BACKGROUND: HIV infection is the highest cause of death worldwide and presenting eventually with ENT regions. OBJECTIVE: This study is to determine the prevalence of hearing loss and hearing patterns among adults Nigerians with HIV and causal relationships between CD4+ counts with the degree of hearing impairments. METHODS: This prospective study was carried out among all consecutive HIV positive patients attending the clinic at the University of Ilorin teaching hospital (U.I.T.H.), Ilorin, Nigeria between January and July, 2008. They all had audiological assessments with a pure tone audiometer within the frequency range 250 to 8,000 Hz to determine their hearing thresholds together with their CD+ counts estimations. RESULTS: 89 were evaluated in the age range of 18 to 56 years (Mean 36.4 years, SD of 8.82) and the modal age group was 21-39 years (59.6%), 40-56 years (38.2%).There were 51 males (57.3%) and 38 females (42.7%) with a male/female ratio of 1.3:1.0. Otological symptoms included tinnitus (15.7%), vertigo (15.7%), otalgia (14.6%) and hard of hearing (10%). Examinations showed bilateral serous Otitis media (glue ear) in 58 patients (65.1%) with no affectation of the facial nerves. PTA showed mixed, conductive and SNHL in 32 patients (36%), 20 patients (22.5%), 9 patients (10.1%) respectively and only 15(16.9%) had normal hearing thresholds. The CD4+ counts ranged between 12 to 616. CD4 counts with hearing loss mostly < 300mm3. CONCLUSION: The prevalence of hearing loss is 87% among HIV infected patients, mostly mixed HLwith causal relationships between reduced CD4+ counts of less than 300/mm3 with severity of hearing loss. The hearing loss can interfere with the communication and specific knowledge vital to the development of best practices towards ensuring the inclusion of hearing impaired in HIV/AIDS prevention and treatment programmes.

    BACKGROUND/AIM: Various degrees of hearing loss have been associated with sickle cell anaemia, especially of the sensorineural type (SNHL). However, there is little information on hearing pattern among sickle cell children in Nigeria. This study is to determine the prevalence of sensorineural hearing loss (SNHL) among children with sickle cell anaemia (SCA). PATIENTS AND METHODS: Eighty (80) stable children aged 4-15 with Hbss attending the pediatric sickle cell clinic and also 60 control patients with HbAA, matched for age, sex at the pediatric general medical clinic of the University of Ilorin teaching hospital, Ilorin, Nigeria, all had prospective study of their pure tone audiological assessment (PTA) and tympanometric evaluations done over a year period. RESULTS: Their age range was 4-15 years with a mean of 9.4 for the Hbss and 9.7 for the control group. The male/female ratio was 1.3:1 and 1.5:1 for SCA and control subjects respectively. 25 subjects (50 ears) had abnormal audiograms among the SCA subjects and OME was the cause in 22 subjects and only three (3) had mild SNHL which was bilateral. However, in the control group 15 had abnormal audiograms and all were due to OME and none had SNHL. OME was bilateral in 19 subjects with SCA, two on the left and only one on the right. In the control group, 11 of the OME was bilateral and only four were on the left side. The prevalence of SNHL was 3.8% and OME was 27.5%. CONCLUSION: We have found a prevalence rate for SNHL of 3.8% for 80 subjects with HbSS, and all cases have been a mild bilateral high frequency SNHL. Our findings suggested that SNHL is uncommon in early childhood, specifically during the years of language acquisition and early schooling. This could mean an age dependant prevalence rate of SNHL among SCA patients. However, no difference in the incidence of OME among both groups which can lead to educational difficulties from the resultant speech and language defects.
