Comparing the prognosis of patient with alcohol and nonalcohol-Associated cirrhosis with bacteremia

Abstract

Aims: Patients with liver cirrhosis are more susceptible to bacteremia and more likely to have a poor prognosis in comparison to healthy individuals. Studies on the role of alcohol in cirrhotic patients with bacteremia are limited. Our study aimed to investigate the clinical characteristics and prognostic differences between the patients with alcohol and non-alcohol-associated cirrhosis with bacteremia. Methods: A single-center, retrospective cohort study was conducted among adult patients who presented to the emergency department from January 2015 to December 2018. All patients diagnosed with liver cirrhosis and bacteremia were enrolled and divided into alcohol-associated and non-alcohol-associated groups according to the etiology of their cirrhosis. We compared their clinical characteristics, laboratory results, microbiological data, and infection source as well as outcome measurements between the two groups. Results: A total of 112 cirrhotic patients with bacteremia (alcohol-associated: 67; non-alcohol-associated: 45) were eligible for this study. In comparison with the non-alcohol-associated group, patients in the alcohol-associated group had a significantly higher rate of intensive care unit transfer (41.8% vs. 22.2%, P = 0.04), septic shock occurrence (56.7% vs. 35.6%, P = 0.04) and 30-day mortality risk (37.3% vs. 15.6%, P = 0.02). Moreover, alcohol-associated cirrhosis and Model for End-Stage Liver Disease score were independent predictors of 30-day mortality in cirrhotic patients with bacteremia. Conclusions: The etiology of liver cirrhosis influences the outcomes of patients with bacteremia as well as the severity of their cirrhosis.
