Clostridium difficile-associated diarrhoea in uremic patients
European Journal of Clinical Microbiology
|June 1, 1987
Summary
This study investigated Clostridium difficile-associated diarrhea in a nephrology ward, finding uremic patients are more susceptible. Increased Clostridium species in uremic patients predispose them to these infections, even without antibiotic use.
Area of Science:
- Infectious Diseases
- Gastroenterology
- Nephrology
Background:
- Clostridium difficile-associated diarrhea (CDAD) is a significant concern in healthcare settings.
- Nephrology patients, particularly those with uremia, may have unique risk factors for CDAD.
Purpose of the Study:
- To investigate the epidemiology and risk factors of a Clostridium difficile outbreak in a nephrology ward.
- To determine the role of uremia and gut microbiota in Clostridium difficile susceptibility.
Main Methods:
- Conducted a two-year investigation of 94 CDAD episodes in 62 patients.
- Performed quantitative stool cultures on uremic patients without diarrhea and healthy controls.
- Analyzed environmental samples for Clostridium difficile presence.
Main Results:
- All diarrheal episodes were linked to Clostridium difficile; no other pathogens were found.
- Sixteen patients experienced 32 relapses, with 14 occurring without prior antibiotic exposure.
- Uremic patients showed a significantly higher abundance of Clostridium species in stools compared to controls.
- Clostridium difficile was not detected in the patient environment.
Conclusions:
- Uremic patients are predisposed to Clostridium difficile infections.
- Altered gut microbiota, specifically increased Clostridium species, may contribute to this predisposition in uremic patients.
- Relapses can occur even without antibiotic exposure, suggesting other factors are involved.
