Abstract:
Background/Aims:Acute-on-chronic liver failure (ACLF) is a widely recognized concept in which acute decompensation (AD) in patients with cirrhosis results in organ failure and high short-term mortality. On the other hand, few studies reflecting the various etiologies of cirrhosis are available. This study examined the clinical features of patients with hepatitis C virus (HCV)-related ACLF.
Methods:Between January 2005 and December 2018, 109 HCV-related cirrhosis patients hospitalized for AD (ascites, hepatic encephalopathy, gastrointestinal hemorrhage, and bacterial infection) were enrolled for ACLF defined by the European Association for the Study of the Liver (EASL).
Results:ACLF developed in 35 patients (32.1%) on admission. Eight, eight, and 19 patients had ACLF grades 1, 2, and 3, respectively. The 28-day and 90-day mortality rates were very low (2.7% and 5.4%, respectively) in patients without ACLF and very high (60.0% and 74.3%, respectively) in those with ACLF. In patients with HCV-related ACLF, compared to previous studies on hepatitis B virus-related ACLF and alcohol-related ACLF, the prevalence of liver failure was very low (17.1%), whereas that of kidney failure was very high (71.4%). Compared with all other prognostic scores, the Chronic liver failure Consortium Organ Failure score predicted the 90-day mortality most accurately, with an area under the receiver operator characteristic of 0.921.
Conclusions:HCV-related ACLF has unique clinical characteristics distinct from hepatitis B virus-related and alcohol-related ACLF. ACLF defined by EASL can be useful for predicting the short-term mortality in HCV-related cirrhosis.
