Microbiological profile of chronic suppurative otits media among HIV infected children in South Eastern Nigeria

Abstract

Background: Immune compromised HIV/AIDS infected children have consistently shown a higher prevalence of chronic suppurative otitis media than their immune competent counterparts.This study aimed to compare the microbial isolates from ear discharges in HIV infected and non infected children

Method: This was a Hospital based prospective cohort study designed to determine the relative prevalence of the common organisms present in chronically discharging ears of HIV infected children and their antimicrobial sensitivities and compare that of age and sex matched non HIV infected children. Fifty HIV infected children being followed up at the paediatric HIV clinic of a tertiary health facility, had ear swabs obtained for culture and antimicrobial sensitivity.The same was done for another cohort of fifty age and sex matched non HIV infected children.

Results: The mean age of the study population and controls were 6years 11months (SD 0.96) and 7years 11 months (SD 1.00) respectively.Male to female ratio for each group was 1:1.Ear discharge was bilateral in 27(54%) HIV infected children and in 35(70%) of the controls.The most prevalent bacterial isolate in both groups was Pseudomonas aeruginosa though it was more prevalent in HIV infected children(P=0.005). Fungal isolates were commoner in non HIV infected children(P=0.001).Ninety percent sensitivity to the 4 Quinolones was recorded by isolates in HIV infected children while sensitivity to the Aminoglycosides was greater in non HIV infected children

Conclusion: Pseudomonas aeruginosa is the predominant organism isolated from HIV infected children with chronic otitis media.Fungal isolates are less frequently encountered in ear discharges of HIV infected children. The 4 Quinolones are the drugs of choice in treatment of Chronic suppurative otitis media in HIV infected children.
