ARTICLE HIGHLIGHTS
Research background

Clostridium difficile (C. difficile) is one of the major causes of nosocomial diarrhea and associated morbidity and mortality. The risk factors of C. difficile are historically established. Cirrhosis is a major disease burden in the United States health care system. The risk of morbidity and mortality is higher in cirrhotic patients who acquire C. difficile infection.

Research motivation

This research was motivated by the lack of recent large population study describing the risk factors of C. difficile in liver cirrhotic patients. We also wanted to study the association in patient cohorts who underwent liver transplant as it was not done previously with such higher sample size.

Research objectives

To determine the prevalence of C. difficile infection in patients with liver cirrhosis and to establish the risk factors of C. difficile infection in patients with liver cirrhosis with special emphasis on liver transplantation cohort.

Research methods

The authors used the Explorys database to obtain data that was classified using SNOMED diagnostic codes. Prevalence and association were calculated using multi-variate regression and SPS Software. Details are in the main manuscript.

Research results

The prevalence of C. difficile infection (CDI) amongst the liver cirrhosis population was 134.93 per 100.000 vs 19.06 per 100.000 in non-cirrhotic patients. The multivariate analysis model showed that cirrhotic patients were more likely to develop CDI.

Research conclusions

This research study concluded that cirrhotic patients have a significantly higher CDI prevalence, and liver cirrhosis may be an independent risk factor for CDI.

Research perspectives

There is a possibility of reducing the CDI mortality in cirrhotic patients by screening them for CDI. Future prospective studies are needed in this regard.
