Abstract
Suppression of hepatitis B virus (HBV) replication with nucelos(t)ide analogues should be considered for patients with chronic hepatitis D virus (HDV) infection and ongoing HBV replication. To verify the clinical outcome after long-term entecavir or tenofovir treatment in patients with advanced fibrosis/cirrhosis, ineligible to peg-interferon therapy. Patients were prospectively followed-up at 3-6month intervals; measured outcomes were decompensation, hepatocellular carcinoma (HCC), liver transplant and liver related death. HBV monoinfected patients receiving the same treatment served as reference after 1:1 matching by age, gender, platelet count, albumin level, bilirubin and INR. 56 HDV patients (48 with cirrhosis; median follow-up 50months) were enrolled; all achieved HBV DNA suppression. Death or liver transplant occurred in 19 patients, with a rate (n/1000 patient-months) of 2.92 in HDV patients vs 0.38 in HBV monoinfected patients (P<0.001); similarly, decompensation occurred at a rate of 1.53 vs 0.13 (P=0.015), respectively, and the rate of HCC was almost thrice in HDV cohort (3.12 vs 1.12; P=0.02) Platelet count, Child-Pugh score and marginally HDV infection were associated with HCC development. Patients with HDV infection and advanced liver disease maintain an increased risk of severe clinical events as compared with HBV monoinfected patients, during prolonged HBV DNA suppression with potent NA.
