Treatment of patients with cirrhosis

Patients with

cirrhosis

PEG-IFN may increase the risk of bacteraemic infection and hepatic decompensation

in patients with advanced cirrhosis

Among NAs, TDF or ETV are preferred because of their potency and minimal risk of

resistance

LAM should not be used

Close monitoring of HBV DNA every 3 months at least during the first year of therapy

and until HBV DNA undetectability is important

Patients with

decompensated

cirrhosis

Patients should be treated in specialized liver units and may be candidates for liver

transplantation

NA treatment is indicated irrespective of HBV DNA level to prevent reactivation

(PEG-)IFN is contraindicated

ETV or TDF should be used

ETV dose for patients with decompensated cirrhosis is 1 mg once daily

Lactic acidosis has been reported to develop in some NA (particularly ETV)

treated patients with advanced decompensated cirrhosis (MELD score >20),

therefore clinical and laboratory parameters should be closely monitored

Patients after liver

transplantation

Pre-transplant therapy with a potent NA with a high barrier to resistance is

recommended for all HBsAg+ patients undergoing liver transplantation
