Prevalence and etiological agents for chronic suppurative otitis media in a tertiary hospital in Tanzania

Abstract

Objective Chronic suppurative otitis media is among the most common otological condition reported in otorhinolaryngology practice commonly attributing to preventable hearing loss. The aim of this study was to determine the prevalence and etiological agents for chronic suppurative otitis media in our department. Results A total of 5591 patients were recruited in this study and only 79 (1.4%) had chronic suppurative otitis media. A male preponderance 43 (54.4%) was noted in this study and the left ear (58.2%) was more commonly affected compared to the right ear. Central perforation was the commonest pattern of presentation and was reported in 53% of cases though none had attic perforation. Of the 81 processed ear swabs, microbial growth was seen in majority 80 (98.8%) whilst one sample showed no microbial growth whereas 52.5% had polymicrobial growth. Among the isolates, most were gram negative species accounting for 59.7% while gram positive bacteria accounted for 25.6% and fungi accounted for 14.7%. Most of these isolates were facultative anaerobes. Klebsiella pneumoniae (20.2%) was the commonest isolates while Escherichia coli and Pseudomonas aeruginosa were equally least isolated (10.9%). Tested isolates were most sensitive to Ciprofloxacin, Gentamycin, Ceftriaxone and Amikacin and least sensitive to Amoxicillin/clavulanic acid and Ampicillin.

Aetiology of ear infection and antimicrobial susceptibility pattern among patients attending otorhinolaryngology clinic at a tertiary hospital in Dar es Salaam, Tanzania: a hospital-based cross-sectional study

“…The study found that many ear infections are of bacterial aetiology. The finding is similar to studies done in Tanzania by Kennedy et al in Morogoro, 4 Zephania et al in Dar es Salaam, 15 Martha et al in Mwanza 3 and other studies in Kenya and India. 16 17 Furthermore, we observed that S. aureus and P.s aeruginosa are ear infections’ leading bacterial aetiological agents, similar to previous studies in Tanzania, Nigeria, Angola, Kenya and India.…”

A comparative study of isolation of microbial flora in ears

“…In the current study, the culture yield compared to the side of the ear showed a statistically significant p-value (0.015) (Table 4). 12,13 In the current study, the presence of pus in the right ear (51%) and pus in the left was reported in (49%) of the patients. However, previous studies by Abraham et al infer that the right ear was affected more.…”

“…Rohan et al have similar findings where Pseudomonas species were the most common 14. In the study by Gupta et al and Abraham et al, Klebsiella species was the most common 12,15.…”

Prevalence and Antibiotic Sensitivity Profile of Bacteria in Patients with Ear Infections

“…The present study indicated that patients aged 10-19 years had the highest incidence of ear infections, which is consistent with previous studies which reported that most ear infections occurred in people less than 20 years old. [13][14][15][16] The short, broad, and straight structure of the eustachian tube, in addition to poor hygiene, a weakened immune system, frequent exposure to upper respiratory tract infections, and malnutrition may all contribute to the higher prevalence of ear infections in children compared to that observed in adults. 3,8,17 Furthermore, ear infections were slightly more common in men than women (58% vs 42%, respectively), but no significant difference was observed, which agrees with the findings of previous studies.…”
