Prevalence of chronic ear disease among HIV+ children in Sub-Saharan Africa.

OBJECTIVES: To determine the prevalence of chronic ear disease in HIV+, highly active anti-retroviral therapy (HAART)-treated children and compare this to the prevalence in healthy children of similar age living in a similar setting.

INTRODUCTION: From previous clinical work in Ethiopia, we suspected that chronic middle ear disease was common both in the general pediatric population and especially among children with HIV/AIDS. Few studies have examined the prevalence of chronic ear disease in HIV + children, particularly in those treated with HAART.

METHODS: Full examination of the head and neck was performed by otolaryngologists. This including cleaning of cerumen, otoscopy and microscopic otoscopy when needed. Patient's medical records were reviewed. Presence or absence of tympanic membrane (TM) perforation (unilateral or bilateral), tympanosclerosis, TM atrophy, otorrhea and/or cholesteatoma was documented.

RESULTS: 112 HIV+ and 162 healthy (HIVU) children were included. Prevalence of TM perforations was 17% in the HIV + infected versus 3% in the HIVU (Fisher's-Exact-Test; OR: 7.2, 95% CI 2.5-20, p-value <0.0001). Presence of unilateral TM perforations was 12% in the HIV + population and 2% in the HIVU population (Fisher's-Exact-Test; OR: 6.8, 95% CI 2.0-22, p-value 0.002). The presence of bilateral perforations was 4% in the HIV + population and 1% in the HIVU population (Fisher's-Exact-Test; OR: 6.8, 95% CI 1.1-42, p-value 0.088). In the HIV + cohort, 2% were diagnosed with cholesteatoma compared to 0% in the HIVU population (95% CI HIV+ 0.002-0.06; HIVU 0.0-0.02) and 8% of HIV + subjects had active middle ear discharge, compared to 0% in the HIVU population (95% CI HIV+ 0.04-0.1; HIVU 0.0-0.02). Neither tympanosclerosis nor tympanic membrane atrophy was more frequent in the HIV + population compared to the HIVU population. Persistent or recurrent TM perforation was not more frequent in children with prior tympanoplasty in the HIV + population compared to the HIVU population.

CONCLUSION: TM perforations are significantly more common in HAART-treated HIV + children than in healthy, age-matched HIVU population. Otorrhea and cholesteatoma were found only in the HIV + cohort.
