Clostridium difficile is a common cause of antibiotic-associated diarrhea. Treatment involves metronidazole and vancomycin, with probiotics for recurrent infections, emphasizing infection control to prevent costs.

Area of Science:

  • Medical Microbiology
  • Infectious Diseases
  • Hospital Epidemiology

Background:

  • Clostridium difficile is a significant nosocomial pathogen.
  • It is responsible for approximately 20% of antibiotic-associated diarrhea cases.
  • Infections range from mild diarrhea to severe toxic megacolon.

Purpose of the Study:

  • To review the microbiology, pathogenesis, and diagnosis of Clostridium difficile.
  • To examine recommended therapies for Clostridium difficile infections.
  • To inform preventive health care strategies.

Main Methods:

  • Literature search of MEDLINE using MeSH headings.
  • Inclusion of controlled trials, case-control studies, and observational reviews.
  • Focus on diagnostic methods and therapeutic recommendations.

Main Results:

  • Diagnosis relies on detecting clostridial toxin in stool or pseudomembranes via sigmoidoscopy.
  • First-line therapy is metronidazole; vancomycin is used for treatment failure.
  • Relapse management includes further metronidazole, tapering vancomycin, or probiotics.

Conclusions:

  • Clostridium difficile is a critical healthcare-associated pathogen.
  • Prudent antibiotic use and strict infection control are essential.
  • Effective management strategies are necessary to mitigate healthcare costs.
