Vancomycin-resistant enterococci. The 'superbug' scourge that's coming your way
1Department of Medicine, Oregon Health Sciences University, Portland, USA.
Abstract:
Strains of vancomycin-resistant enterococci (VRE) have emerged and spread widely throughout the United States during the last few years. Multiply-resistant strains of Enterococcus faecium are especially troublesome because they are often resistant to all commercially available antimicrobial agents. At present, VRE infections occur most often in hospitalized patients with severe underlying disease who have undergone invasive procedures and received prolonged courses of broad-spectrum antimicrobial therapy. Because therapeutic options are limited, prevention of spread from patients with known cases to other vulnerable patients is essential.
Insights
Vancomycin-resistant enterococci (VRE) are a growing threat, particularly multiply-resistant Enterococcus faecium strains. Limited treatment options necessitate strict infection control to prevent VRE spread in hospitals.
Area of Science:
- Infectious Diseases
- Microbiology
- Hospital Epidemiology
Background:
- Vancomycin-resistant enterococci (VRE) have significantly increased in prevalence across the United States.
- Multiply-resistant Enterococcus faecium strains pose a particular challenge due to resistance to most available antimicrobial agents.
- VRE infections predominantly affect hospitalized patients with serious underlying conditions, invasive procedures, and extensive broad-spectrum antibiotic use.
Purpose of the Study:
- To highlight the emergence and spread of vancomycin-resistant enterococci (VRE).
- To emphasize the clinical challenges posed by multiply-resistant Enterococcus faecium.
- To underscore the critical need for preventing VRE transmission in healthcare settings.
Main Methods:
- Literature review on VRE epidemiology and resistance patterns.
- Analysis of clinical data regarding VRE infection risk factors.
- Discussion of current therapeutic limitations and infection control strategies.
Main Results:
- Widespread emergence and dissemination of VRE strains noted.
- Enterococcus faecium identified as a particularly problematic VRE species due to multidrug resistance.
- Hospitalized, critically ill patients receiving prolonged antibiotic therapy are at highest risk.
Conclusions:
- The limited therapeutic armamentarium for VRE infections demands stringent preventive measures.
- Preventing the transmission of VRE from infected patients to vulnerable individuals is paramount.
- Enhanced infection control protocols are essential to curb the spread of VRE in healthcare facilities.
