Abstract

Background: ESBL-producing Enterobacteriaceae (ESBL-PE) represent a significant global health threat. In response to this growing concern and the lack of a surveillance system for ESBL-PE infections in Egypt, we conducted this meta-analysis. In this study, we aimed to quantify the prevalence of ESBL-PE based on the source of infection and characterize their molecular dissemination. Additionally, we sought to uncover temporal trends to assess the spread of ESBL-PE over time.

Methods: A comprehensive literature search was conducted in PubMed, Scopus, Google Scholar, Web of Science, and the Egyptian Knowledge Bank to identify studies that: (1) report the prevalence of ESBL-PE in Egypt; (2) use valid detection methods; (3) involve clinical specimens; and (4) were published between 2010 and 2024. The quality of the included studies was evaluated using the "Joanna Briggs Institute Critical Appraisal Checklist". Meta-analysis was performed using the R meta package, reporting pooled prevalence with 95% confidence intervals (CI) via a random effects model.

Results: This meta-analysis included 34 studies with 4,528 isolates, spanning 2007 to 2023. The overall prevalence of ESBL-PE in Egypt was 60% (95% CI: 54-65). The leave-one-out meta-analysis demonstrated the absence of influential outliers and Egger's test indicated no evidence of publication bias (P = 0.25). The prevalence of ESBL-PE was 62% (95% CI: 55-68) in nosocomial infections and 65% (95% CI: 52-75) in community-acquired infections, with no statistically significant difference (P = 0.68). The prevalence of ESBL producers in E. coli (64%) and K. pneumoniae (63%) is higher than in Proteus mirabilis (46%) (P = 0.06). Temporal analysis showed a stable ESBL prevalence over time. Moreover, in phenotypically confirmed ESBL-producing, E. coli harboring blaCTX-M was most prevalent (73%), followed by blaTEM (60%) and blaSHV (22%), with significant differences (P < 0.01). Subsequent analysis identified blaCTX-M-15 as the predominant variant of the blaCTX-M gene.

Conclusions: The prevalence of ESBL-PE in Egypt is alarmingly high at 60%. The observed high rates in both hospital and community-acquired infections underscore the need for public health strategies targeting both settings. One limitation of this study is the high heterogeneity, which partly attributed to regional and institutional variations in antibiotic use and stewardship practices.

期刊介绍: Antimicrobial Resistance and Infection Control is a global forum for all those working on the prevention, diagnostic and treatment of health-care associated infections and antimicrobial resistance development in all health-care settings. The journal covers a broad spectrum of preeminent practices and best available data to the top interventional and translational research, and innovative developments in the field of infection control.
