The life expectancy of patients with cirrhosis in the decompensated phase due to hepatitis B virus also varies. Patients in the decompensated phase with a Child-Pugh score of B have a slightly less severe clinical picture of recurrent ascites, no or mild hepatic encephalopathy, no skin petechiae and scanty urination compared to those in the decompensated phase with a Child classification of C. Patients in the decompensated phase with a Child-Pugh score of B have a slightly less severe clinical picture of recurrent ascites, no or mild hepatic encephalopathy, no skin petechiae and scanty urination. With treatment they can also recover to the compensated stage of cirrhosis, only alternating between compensated and decompensated stages, and the 5-year survival rate for such patients is 35%. In patients with persistent ascites, severe hepatic encephalopathy, or even severe changes in coagulation such as skin petechiae, or hepatorenal syndrome with oliguria, the 5-year survival rate for patients with persistent cirrhotic decompensation of ChildC grade is only 15%.
