Identification of Risk Factors Associated With Clostridium difficile Infection in Liver Transplantation Recipients: A...

Area of Science:

• Hepatology
• Transplantation Medicine
• Infectious Diseases

Background:

• Clostridium difficile infection (CDI) is a significant cause of healthcare-associated diarrhea, with increasing incidence and severity in liver transplant recipients.
• Liver transplantation inherently involves risk factors for CDI, including immunosuppression, abdominal surgery, and broad-spectrum antibiotic use.

Purpose of the Study:

• To identify risk factors for CDI in liver transplant recipients.
• To examine the association between post-transplantation CDI and transplant outcomes.

Main Methods:

• Single-center retrospective case-control study.
• Evaluated 65 liver transplant recipients from January 2008 to December 2012.
• Defined CDI cases as positive C. difficile tests within one year post-transplantation.

Main Results:

• 15 (23%) patients developed CDI, with a median onset of 65 days post-transplant; over half had severe infections.
• Significant risk factors for CDI included prior CDI history, proton-pump inhibitor use, pre-transplant antimicrobial therapy, prolonged pre-transplant hospital stay, and chronic kidney disease.
• No significant differences in 6-month or 12-month patient survival were observed between CDI cases and controls.

Conclusions:

• Specific factors increase CDI risk in liver transplant patients.
• Early identification and management of these risk factors may be crucial for preventing CDI.
• CDI did not significantly impact short-term survival in this cohort.
