RESUMO
@# 【Objective】To study the correlation between hepatocellular jaundice and liver stiffness measurement and reflect the changes in patients with acute-on-chronic liver failure（ACLF）.【Methods】Between January 2015 and March 2016，a total of 150 patients with ACLF-HBV infection were enrolled to collect clinical data，2D-SWE and biochemical variables. According to data distribution，correlation of total bilirubin with LSM by 2D-SWE was assessed by Pearson correlation analysis.【Results】One hundred and twenty-one patients were analyzed and divided into two groups：descended TB group and elevated TB group. For descended TB group，LSM decreased 5.1（2.2～6.6）kPa. For elevated TB group， LSM increased 6.2（1.2～12.8）kPa. A significant parallel correlation between TB and LSM value either the descended TB group or the elevated TB group. For descended TB group，accompanied with the decrease of LSM，patients reached clinical improvement standard and their average hospitalization time was 30 ± 15 days. Six patients underwent liver trans⁃ plantation in the elevated TB group，and showed TB level higher than twenty ULN（the upper limit of normal），ac⁃ companied with increased LSM value. Histological characteristics of these patients showed submassive hepatic necrosis. 【Conclusion】The degree of hepatic necrosis aggravation in patients with ACLF，which results in the continuous increase of TB and LSM，reflects the aggravation of patients′ condition；on the contrary，the decline in value of LSM reflects the improvement of patients′ condition.
