Abstract
Objectives
This systematic review and meta-analysis aimed to quantify mortality associated with MRSA clones and evaluate the contribution of specific molecular features to outcome variation.
Methods
Databases including PubMed, Scopus, Web of Science, and Google Scholar were searched for studies reporting mortality among patients with MRSA infection and associated molecular typing data, including clonal complex, sequence type and SCCmec type. Results were presented in thematic narratives, tables and figures. A random-effects meta-analysis was performed to estimate pooled mortality and prevalence proportions.
Results
Twenty-seven included studies reported on MRSA isolates from 12 different countries. The overall pooled mortality was 22.47% (95% CI: 17.31–28.07), with the highest mortality observed in Europe. Among MRSA clonal complexes, the highest mortality was observed among CC5 (50.75%), followed by CC8 (37.56%). Although ST72 (66.16%) was the most prevalent sequence type, the highest mortality rates were observed in ST764 (38.74%) and ST1 (38.72%). SCCmec type IV (36.95%) was dominant but had a lower mortality rate (18.71%) compared to types II (39.09%) and III (27.52%).
Conclusions
The clear dominance and lethality of specific lineages affirm the clinical utility of molecular diagnostics in guiding treatment and predicting outcomes. These insights call for an expansion of MRSA typing programs in hospital laboratories and national surveillance systems.
期刊介绍:
The Journal of Global Antimicrobial Resistance (JGAR) is a quarterly online journal run by an international Editorial Board that focuses on the global spread of antibiotic-resistant microbes.
JGAR is a dedicated journal for all professionals working in research, health care, the environment and animal infection control, aiming to track the resistance threat worldwide and provides a single voice devoted to antimicrobial resistance (AMR).
Featuring peer-reviewed and up to date research articles, reviews, short notes and hot topics JGAR covers the key topics related to antibacterial, antiviral, antifungal and antiparasitic resistance.
