Clinical Trial Summary

ACLF is a distinct syndrome that is different from chronic progressive hepatic decompensation. In most cases of ACLF, patients present initially with clinical manifestations of a decompensating event, usually renal impairment, worsening of abdominal ascites, jaundice or Hepatic encephalopathy (HE) and often precipitated by bacterial infection.

Clinical Trial Description

Liver cirrhosis is the result of progressive fibrosis in patients with chronic liver disease of any etiology, and is associated with a poor prognosis, once hepatic decompensation starts.

Cirrhosis has two main phases: the compensated phase, where patients maintain preserved liver synthetic function and have no significant extrahepatic organ impairment; this is to be compared with a decompensated phase, where increasing ascites and loss of liver synthetic function, together with presentation with other organ impairment, are common clinical presentations. Renal failure, hepatic encephalopathy (HE), recurrent infections and upper gastrointestinal bleeding from worsening portal hypertension are considered end- stage complications of decompensated cirrhosis. The term acute- on- chronic liver failure (ACLF) is used to describe the clinical syndrome where acute hepatic decompensation leads to organ failures in the setting of liver cirrhosis.

Although there is not a universal agreement about the definition of acute on chronic liver failure (ACLF), there is a wide agreement that ACLF is a distinct syndrome that is different from chronic progressive hepatic decompensation. In most cases of ACLF, patients present initially with clinical manifestations of a decompensating event, usually renal impairment, worsening of abdominal ascites, jaundice or Hepatic encephalopathy (HE) and often precipitated by bacterial infection.

In the CANONIC study, ACLF was defined as 'an acute deterioration of pre- existing chronic liver disease, sometimes related to a clear precipitating event, and associated with increased mortality at 28 days.

The North American consortium for studying liver disease (NACSELD) proposed another definition of ACLF that defines it as 'a condition in patients with underlying chronic liver disease with or without cirrhosis that is associated with mortality within 3 months in the absence of treatment of the underlying liver disease, liver support, or liver transplantation'.

Currently, the term ACLF is still a relatively new entity that has not been very well studied or investigated in our medical research environment. There are no major studies that aimed at looking at the incidence of ACLF in our medical settings. ;
