Studies revealed a higher mortality when CDI is associated with liver cirrhosis. We aim to present the outcomes of CDI among patients with and without liver cirrhosis and to analyze the association of Model for End-Stage Liver Disease (MELD) and Child-Pugh (CPT) scoring with the severity of CDI.Methods: A retrospective observational study was conducted in hospitalized patients with CDI diagnosed via a 2-step method – glutamate dehydrogenase (GDH) and toxin polymerase chain reaction (PCR). Patients with liver cirrhosis were identified based on ICD codes and chart review. MELD and CPT scores were calculated using laboratory parameters at the time of hospitalization. We compared CDI-related mortality in patients with and without cirrhosis and reviewed the CDI severity distribution in cirrhosis patients.Results: A total of 526 patients were included in the study, of which 478 (90.87%) were non-cirrhotic and 48 (9.13%) were cirrhotic patients. Mortality rate was higher in cirrhosis group compared to the non-cirrhosis group (39.6% vs. 14.6%,P = 0.001). Among cirrhosis patients, those who survived had lower MELD score compared to the expired group (14.9 vs. 18.58, P = 0.106). There was no correlation of mortality based on CPT score in the cirrhosis group (P = 0.062). In post hoc analysis comparing the severity of CDI to liver cirrhosis, cirrhosis patients are more likely to present with severe-complicated disease. Multivariate logistic regression identified liver cirrhosis, severe-complicated CDI and serum albumin level as independent predictors of mortality.Conclusion: Our study noted a more severe disease presentation and higher mortality in patients with cirrhosis admitted with CDI. Further studies are required for better understanding of the clinical course of CDI in cirrhosis and to evaluate the need for early intervention in this patient group.Keywords: clostridioides difficile infection; CDI, cirrhosis, mortality, severity, Model for End-Stage Liver Disease; MELD, Child-Pugh; CPT
