Clostridium difficile infections (CDI) cause mild to severe symptoms, with risk factors including age and hospitalization. Prevention involves minimizing antimicrobial exposure and limiting transmission.
Area of Science:
- Microbiology
- Infectious Diseases
- Gastroenterology
Background:
- Clostridium difficile is an anaerobic, spore-forming enteropathogen causing antibiotic-associated diarrhea and pseudomembranous colitis.
- Clostridium difficile associated-infections (CDI) present with a spectrum of illness, from mild diarrhea to life-threatening conditions like toxic megacolon and perforation.
Purpose of the Study:
- To review the clinical features, risk factors, and management of Clostridium difficile associated-infections (CDI).
- To highlight the emergence of a hypervirulent Clostridium difficile strain (PCR-ribotype 027) and its impact.
Main Methods:
- Literature review of Clostridium difficile associated-infections (CDI).
- Analysis of virulence factors, including toxins A, B, and binary toxin.
- Identification of risk factors such as advanced age, hospitalization, and antibiotic use.
Main Results:
- Clostridium difficile associated-infections (CDI) range from mild diarrhea to severe, fatal outcomes.
- Key risk factors include age over 65, hospitalization, and recent antibiotic therapy.
- A hypervirulent Clostridium difficile strain (PCR-ribotype 027) has emerged, causing severe outbreaks.
Conclusions:
- Oral metronidazole and vancomycin are effective treatments for Clostridium difficile associated-infections (CDI).
- Controlling CDI requires preventing its emergence by judicious antimicrobial use and implementing strict infection control measures to limit cross-transmission.

HAIs significantly increase the cost of health care. Extended stays in healthcare institutions, increased disability, increased costs of medications, including specialized antibiotics, and prolonged recovery times add to the patient's expenses and the healthcare institution and funding bodies.
