Abstract
OBJECTIVE: Acute bacterial skin and skin structure infection (ABSSSI) is a common cause of acute admissions in patients with cirrhosis worldwide, but the disease is not well-understood epidemiologically with respect to factors that determine positive blood cultures or patient mortality. The aim of this study was to understand the utility of blood cultures and the association between bacteremia and mortality in cirrhotic patients with ABSSSI. We conducted a retrospective study to investigate factors associated with positive blood cultures and mortality in cirrhotic patients with ABSSSI.
METHODS: A retrospective cohort study of hospitalized adult cirrhotic patients with ABSSSI was conducted in a tertiary hospital in Taiwan between March 2015 and December 2016.
RESULTS: A total of 122 hospitalized cirrhotic patients with ABSSSI were included. The overall mortality rate was 9% (11/122), and 23 patients had positive blood culture results. Comorbidities that were significant risk factors for a positive blood culture included diabetes mellitus, acute kidney injury (AKI), and acute-on-chronic liver failure (ACLF). Significant risk factors evident in laboratory evaluations included higher model for end-stage liver disease (MELD) score, higher serum lactate, and lower serum albumin level. Bacteremia was also a significant factor associated with mortality.
CONCLUSION: A blood culture should be considered for cirrhotic patients with ABSSSI with diabetes mellitus, AKI, ACLF or those exhibiting abnormal albumin, lactate levels, or high MELD score because of the positive correlation between bacteremia and mortality.
