Abstract
INTRODUCTION Vancomycin-resistant Staphylococcus aureus, identified as a "high priority antibiotic-resistant pathogen" by the World Health Organization, poses a significant threat to human health. This systematic review and meta-analysis aimed to estimate the pooled prevalence of vancomycin-resistant Staphylococcus aureus in Ethiopia. METHODS This systematic review and meta-analysis was reported in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Studies that reported VRSA prevalence due to infection or carriage from human clinical specimens were extensively searched in bibliographic databases and grey literatures using entry terms and combination key words. Electronic databases like PubMed, Google Scholar, Wiley Online Library, African Journal Online, Scopus, Science Direct, Embase, and ResearchGate were used to find relevant articles. In addition, the Joanna Briggs Institute quality appraisal tool was used to assess the quality of the included studies. Stata version 14 software was used for statistical analysis. Forest plots using the random-effect model were used to compute the overall pooled prevalence of VRSA and for the subgroup analysis. Heterogeneity was assessed using Cochrane chi-square (I2) statistics. After publication bias was assessed using a funnel plot and Egger's test, trim & fill analysis was carried out. Furthermore, sensitivity analysis was done to assess the impact of a single study on pooled effect size. RESULTS Of the 735 studies identified, 31 studies that fulfilled the eligibility criteria were included for meta-analysis consisted of 14,966 study participants and 2,348 S. aureus isolates. The overall pooled prevalence of VRSA was 14.52% (95% CI: 11.59, 17.44). Significantly high level of heterogeneity was observed among studies (I2 = 93.0%, p < 0.001). The region-based subgroup analysis depicted highest pooled prevalence of 47.74% (95% CI: 17.79, 77.69) in Sidama region, followed by 14.82% (95% CI: 8.68, 19.88) in Amhara region, while Oromia region had the least pooled prevalence 8.07% (95% CI: 4.09, 12.06). The subgroup analysis based on AST methods depicted a significant variation in pooled prevalence of VRSA (6.3% (95% CI: 3.14, 9.43) for MIC-based methods, and 18.4% (95% CI: 14.03, 22.79) for disk diffusion AST method) which clearly showed that disk diffusion AST method overestimates the pooled VRSA prevalence. The total number of S. aureus isolates was found to be the responsible variable for the existence of heterogeneity among studies (p = 0.033). CONCLUSION This study showed an alarmingly high pooled prevalence of VRSA necessitating routine screening, appropriate antibiotic usage, and robust infection prevention measures to manage MRSA infections and control the emergence of drug resistance. Furthermore, mainly attributable to the overestimation of VRSA burden while using disk diffusion method, there is an urgent need to improve the methods to determine vancomycin resistance in Ethiopia and incorporate MIC-based VRSA detection methods in routine clinical laboratory tests, and efforts should be directed at improving it nationally.

Molecular Profile and the Effectiveness of Antimicrobials Drugs Against Staphylococcus aureus and Pseudomonas aeruginosa in the Diagnostic Approaches of Otitis Infection. Infect Drug Resist 2023; 16:4397-4408. [PMID: 37431447 PMCID: PMC10329836 DOI: 10.2147/idr.s418685] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/23/2023] [Accepted: 06/27/2023] [Indexed: 07/12/2023] Open
Abstract
Background Otitis externa and otitis media are two types of ear infections that affect people of all ages, although they are more common in newborns and young children. Antibiotic usage, healthcare, and advanced age all play a role in the development of this illness. Methods Fifty-eight patients with various kinds of infections of the ears were voluntary patients attending the outpatient clinics of the Prince Mutaib Bin Abdulaziz Hospital in Sakaka, Al Jouf, Saudi Arabia, examined to evaluate the role of bacteria and the likely significance of plasmids in their antibiotic resistance as ear infectious agents. Results Staphylococcus aureus and Pseudomonas aeruginosa are the most prevalent bacteria found in ear infections. The greatest number of major bacterial isolates were S. aureus (54%), followed by P. aeruginosa (13%), whereas a smaller number of isolates (3%) were from Streptococcus pyogenes, Bacillus subtilis, and Proteus vulgaris, respectively. Mixed growth was noted in 3.4% of instances. The isolation rate for Gram-positive organisms was 72%, while the rate for Gram-negative species was 28%. All the isolates had DNA greater than 14 kilobases. Hind III analysis of the plasmid DNA extracted from the resistant strains of ear infection demonstrated that antibiotic-resistance plasmids were extensively dispersed. Exotoxin A PCR amplification indicated 396 pb PCR-positive DNA for all identified samples, with the exception of three strains for which no band was observed. Patients in the epidemiological study ranged in number, but all were linked together for the purposes of the study because of their shared epidemiological characteristics. Conclusion Vancomycin, linezolid, tigecycline, rifampin, and daptomycin are all antibiotics that have been shown to be effective against S. aureus and P. aeruginosa. Microbiological pattern evaluation and antibiotic sensitivity patterns of the microorganisms providing empirical antibiotics are becoming increasingly crucial to minimize issues and the development of antibiotic-resistant strains.

Microbiology and Drug Susceptibility Pattern of Bacterial Isolates from Patients with Chronic Suppurative Otitis Media at a Tertiary Care Hospital in Somalia. Infect Drug Resist 2022; 15:7733-7739. [PMID: 36597453 PMCID: PMC9805702 DOI: 10.2147/idr.s390886] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/14/2022] [Accepted: 12/20/2022] [Indexed: 12/29/2022] Open
Abstract
Background This study aimed to determine the microbiological profile and antibiotic susceptibility pattern of bacterial isolates obtained from patients with chronic suppurative otitis media (CSOM) presenting to the otorhinolaryngology clinic of a tertiary care hospital in Mogadishu, Somalia. Methods A total of 225 patients diagnosed with chronic suppurative otitis media were included in the study. Samples of middle ear discharge were collected from each patient and cultured using standard microbiological techniques, and bacterial identification was performed. Drug susceptibility pattern was assessed according to the Clinical and Laboratory Standards Institute criteria. Results The study sample (n=225) comprised 122 females and 103 males. Among 225 samples tested, bacterial growth was present in 200 (88.9%) and absent in 25 (11.1%) samples. Of 200 samples with bacterial growth, monomicrobial growth was detected in 176 (88%). Gram-positive bacteria were observed in 40 (22.7%) and Gram-negative bacteria in 136 (77.3%) samples. The bacteriology of the samples with monomicrobial growth consisted of (in decreasing frequency) Pseudomonas spp, Staphylococcus aureus, Escherichia coli, Coagulase-negative staphylococci, Proteus mirabilis, and Klebsiella sp. A high rate of resistance was detected against penicillin antibiotics, erythromycin, tetracycline, and co-trimoxazole. Resistance to cephalosporins, clindamycin, vancomycin, linezolid, daptomycin, quinupristin/dalfopristin, levofloxacin, meropenem, and ertapenem was low. Conclusion While the frequencies of isolated bacterial species were consistent with other reports from the region, differences were observed in the antibiotic resistance of bacterial isolates when examined individually for each antibiotic. Further studies are warranted in the same region and different parts of Somalia, coupled with ongoing assessment of antibiotic susceptibility patterns in CSOM.
