【 摘 要 】

Background: The increasing prevalence of multidrug-resistant Enterobacteriaceae limits the range of active antimicrobial agents, thus worsening clinical outcomes. The objective of this study was to identify the trends in antimicrobial resistance for Enterobacteriaceae in Russia using the databases for the International Network for Optimal Resistance Monitoring (INFORM) and Antimicrobial Testing Leadership and Surveillance (ATLAS) studies between 2012 and 2018. Methods: This subanalysis was performed for 3811 non-duplicate clinical isolates of Enterobacteriaceae to evaluate the in vitro activity of the main classes of antibiotics against relevant clinical isolates from hospitalized patients with complicated infections of different anatomical locations. Results: The lowest susceptibility was observed for colistin (0%), ampicillin (16.4%), and ampicillin/sulbactam (31.1%), whereas the best susceptibility was observed for all combinations containing avibactam (>96%). Among individual antimicrobials, doripenem (3.2%), tigecycline (1.6%), and meropenem (5.9%) exhibited the lowest resistance. Important trends included the decreasing resistance of Enterobacteriaceae to glycylcyclines and the increasing resistance to aminoglycosides and carbapenems. K. pneumoniae strains were most aggressive in terms of the percentage of strains having multidrug resistance (8.3–18.3%, depending on location) and the percentage of ESBL-positive strains (44.8–86.8%). Conclusions: The current patterns and trends of antimicrobial resistance in different bacterial species should be taken into consideration for timely updating of clinical guidelines and local treatment protocols to ensure effective antimicrobial therapy.
