Objective:
To observe the efficacy and safety of de novo combination of Lamivudine(LAM) and Adefovir Dipivoxil (ADV) therapy counter to Entecavir (ETV) monotherapy in patients with chronic hepatitis B (CHB)- related compensated liver cirrhosis.
Methods:
Patients with chronic hepatitis B-related compensated cirrhosis who were initially treated with LAM and ADV for more than 1 year were randomly assigned to two groups, one half replaced with ETV monotherapy, and the other half continued LAM and ADV co-therapy. Liver biochemistry, renal biochemistry, estimated glomerular filtration rate, alpha-fetoprotein, HBV serology markers and serum HBV DNA were measured every 3 months. Urine β2-microglobulin was measured every 6 months And retinol binding protein, followed up for 3 years. The mean values of the two groups were compared with t-test, and the rate of comparison was analyzed by x2 test.
Results:
A total of 580 cases were collected, 290 cases were replaced with ETV monotherapy, the other 290 patients continued to LAM and ADV combination therapy. In the ETV group, the rates of HBV DNA negative conversion at 1 year, 2 years and 3 years were 77.6%, 84.5% and 94.5% respectively, while the HBV DNA negative conversion rates at 1, 2 and 3 years in the LAM and ADV combination groups were 69.3%, 73.4% and 80.3% respectively. Among them, the negative rates of HBV DNA in the second year and the third year were
