Clinical Trial Summary
Cirrhosis is a condition characterized by diffuse fibrosis, severe disruption of the
intrahepatic arterial and venous flow, portal hypertension and, ultimately, liver cell
failure. Traditionally, cirrhosis has been dichotomised in compensated and decompensated, and
the transition to decompensated cirrhosis happens when any of the following hallmarks occurs:
presence of ascites, variceal haemorrhage and/ or hepatic encephalopathy (HE) . In Egypt, HCV
is the main cause of liver cirrhosis followed by HBV
Description:
Cirrhosis is a condition characterized by diffuse fibrosis, severe disruption of the
intrahepatic arterial and venous flow, portal hypertension and, ultimately, liver cell
failure. Traditionally, cirrhosis has been dichotomised in compensated and decompensated, and
the transition to decompensated cirrhosis happens when any of the following hallmarks occurs:
presence of ascites, variceal haemorrhage and/ or hepatic encephalopathy (HE). In Egypt, HCV
is the main cause of liver cirrhosis followed by HBV. Once cirrhosis transitions from the
compensated to the decompensated stage, it is associated with short-term survival (3-5 years)
. The concept of acute-on-chronic liver failure (ACLF) has been widely used to study patients
who underwent artificial support therapies as a bridge to liver transplantation (LT). In
2009, the Asian Pacific Association for the Study of the Liver (APASL) provided the first
consensus on ACLF, defined as "an acute hepatic insult manifesting as jaundice and
coagulopathy, complicated within 4 weeks by ascites and/or encephalopathy". In 2014, the
definition was further expanded to include 'high 28-day mortality'. Therefore, acute on top
of chronic liver failure (ACLF) is defined as a syndrome characterized by acute decompensated
cirrhosis associated with failure of various organs and high short term mortality rate; based
on CANONIC study which is a large scale prospective study, in which the kidneys were the most
common affected organs, followed by liver, coagulation, the brain, circulation and the lungs.
ACLF can occur in patients with chronic liver disease without cirrhosis (type A), with
compensated cirrhosis (type B), and with decompensated cirrhosis (type C) .In many cases, a
precipitating factor linked to the development of ACLF can be identified including alcohol
intake, reactivation of HBV or acute hepatitis due to HAV or HEV, bacterial infection or GI
hemorrhage. The CLIF-C OF score which consists of numbers and types of organ failures (OFs)
including kidneys, liver, coagulation, the brain, circulation, and the lungs is associated
with 28-day and 90-day mortality. Moreover, some specific organ dysfunction such as kidney
dysfunction and moderate HE, when associated with single OF, was also associated with bad
prognosis . On this background, diagnostic criteria of ACLF were established according to the
presence, type and number of OFs.
The severity of ACLF was graded into different stages according to the number of OFs on ACLF
grade 1, grade 2 and grade 3 and mortality correlates with ACLF severity.
To predict prognosis and mortality more accurately. developed CLIF-C-ACLF score which has a
greater prognostic capability than CLIF-C- OF, It consists of the CLIF-C- OF combined with
age and WBCs count. Few studies have addressed the patterns of acute on chronic liver failure
in Egyptian cirrhotic patients . Therefore, we will conduct our study to shed
