Background and Aim: Nosocomial infections caused by gram-negative bacteria are among the most important health-threatening challenges of the current century, particularly following the emergence and spreading of antibiotic-resistance strains. Extended-spectrum beta-lactamase (ESBL), one of the most important antibiotic resistance mechanisms, is spreading worldwide. Surveillance and gathering data on the prevalence of antibiotic resistance and their associated encoding genes could assist in selecting treatment strategies and policies. This systematic review and meta-analysis was designed to assess the prevalence of ESBL-positive bacteria and their resistance genes in medical centers of Kermanshah city, west of Iran.
Materials and Methods: All studies published as original articles were retrieved by searching in EMBASE, Scopus, PubMed/Medline, Google Scholar, and Persian databases of SID and Magiran, using appropriate keywords All published studies in the field were included without time restriction until 30-Mar-2022. Comprehensive Meta-Analysis software was used to analyze the data.
Results: The prevalence of ESBL-positive and multidrug resistance (MDR) bacteria in Kermanshah medical centers were 34.8% and 56.1%, respectively. The highest and lowest prevalence of ESBL-positive bacteria was observed for Enterobacter cloacae (59.14%) and Pseudomonas aeruginosa (4.55%), respectively. The highest and lowest prevalence of the resistance genes were observed for blaOXA-51 (99.3%) and blaKPC (0.6%), respectively. The highest resistance was estimated to mezlocillin antibiotic (92.2%).
Conclusion: This study showed that the prevalence of ESBL-positive and MDR bacteria is high in Kermanshah medical centers, and it provides significant information to health policymakers to implement appropriate strategies to reduce the prevalence of resistant bacteria.
