Acute-on-chronic liver failure exists in patients with hepatitis B virus-related decompensated cirrhosis.

OBJECTIVE

This research sought to verify whether acute-on-chronic liver failure (ACLF) develops in hepatitis B virus (HBV)-related cirrhotic patients with previous decompensation and to identify the similarity between assumed ACLF patients and those with ACLF that developed from compensated cirrhosis.

METHODS

Patients with HBV-related cirrhosis were retrospectively screened and divided into the cirrhotic patients with first acute decompensation (AD) group and those with previous decompensation. Patients' characteristics, changes in laboratory results during hospitalization such as serum levels of total bilirubin (TB), creatinine (Cr) and white blood cell (WBC) counts, the Model for End-Stage Liver Disease (MELD) score and the 28-day and 1-year mortality rates were compared.

RESULTS

Altogether 890 patients were enrolled and divided into the compensated cirrhotic group with first AD (n = 400; 157 of whom diagnosed as ACLF within 28 days after admission according to the European Association for the Study of the Liver-Chronic Liver Failure [EASL-CLIF] criteria) and those with previous decompensation (n = 490; of whom 143 met the ACLF criteria [assumed ACLF]). There was no significant difference in 28-day mortality between the assumed ACLF group with previous decompensation and ACLF group with first AD. The WBC count, TB and Cr levels, international normalized ratio and MELD score exhibited similar variations in both groups at days 1, 7 and 28; however, these values in both ACLF groups significantly differed from the non-ACLF group.

CONCLUSION

HBV-related cirrhotic patients with previous decompensation who met the ACLF criteria had similar characteristic to ACLF patients with first AD.
