Thromboelastography Guides a Multicentre Cluster Controlled Study of Plasma Exchange for Hepatitis B Associated Acute-on-chronic Liver Failure

Thromboelastography Guides a Multicentre Cluster Controlled Study of Plasma Exchange for Hepatitis B Associated Acute on Chronic Liver Failure
In the past ten years, the extracorporeal liver support system has been widely used in clinical practice as a first-line treatment of liver failure.
Plasma exchange (PE) can remove toxic substances in ACLF patients, reduce liver damage, and replenish coagulation factors, albumin and immunoglobulins, thereby improving the liver's microenvironment and accelerating liver regeneration and functional recovery.
The ACLF study showed that PE can improve the symptoms of patients and improve the short-term prognosis of patients, but there are still studies showing that PE does not significantly improve the short-term prognosis of patients.
Therefore, the therapeutic effect of PE on ACLF is still controversial.
We consider that some people may benefit from plasma exchange, and new indicators are needed to guide disease stratification treatment.
Our multi-center prospective data show that plasma exchange has a tendency to improve survival in ACLF-2.
After stratifying with ADP inhibition rate in ACLF-2, patients with ADP inhibition rate greater than 30% will be treated 28 days after PE treatment.
The prognosis is improving.
Therefore, we consider that PE is expected to reduce the mortality of patients with ACLF 2 with an ADP suppression rate greater than 30%, but prospective large-sample clinical studies are still needed.
