Clostridium difficile and vancomycin-resistant enterococcus: the new nosocomial alliance

Area of Science:

• Infectious Diseases
• Microbiology
• Hospital Epidemiology

Background:

• Vancomycin-resistant Enterococcus (VRE) and Clostridium difficile (C. difficile) are significant healthcare-associated pathogens.
• Coinfection with these organisms presents complex clinical challenges.
• Understanding the interplay between C. difficile and VRE is crucial for effective patient management.

Purpose of the Study:

• To determine the frequency of C. difficile and VRE coinfection.
• To assess C. difficile coinfection as a predictor of VRE infection versus colonization.
• To evaluate the impact of C. difficile coinfection on adverse outcomes in VRE patients.

Main Methods:

• Retrospective comparison of patients with C. difficile colitis and VRE (CD/VRE) versus VRE alone.
• Analysis of demographics, comorbidities, prior antibiotic use, and coinfections.
• Statistical evaluation of C. difficile as a predictor for VRE infection/colonization and adverse outcomes.

Main Results:

• C. difficile was isolated in 19.1% of VRE patients.
• C. difficile coinfection did not predict VRE infection/colonization or adverse outcomes like mortality.
• Significant associations were found between vancomycin/metronidazole use and C. difficile coinfection, and between coinfection and funguria.

Conclusions:

• C. difficile coinfection is frequent in VRE patients and associated with other nosocomial infections, such as funguria.
• The emergence of highly virulent pathogens, including vancomycin-resistant C. difficile, poses management challenges.
• Further research is needed to understand the clinical implications of these coinfections.
