Overview

Through regular monitoring of viral load, liver function and immune cell activity, the long-term efficacy of Adefovir in controlling HBV is precisely evaluated. By employing a dual mechanism of "antiviral action plus immune activation", it offers a novel therapeutic option for achieving clinical cure in chronic hepatitis B.

  2. HBV DNA load \> 20,000 copies/mL and HBsAg \< 1,500 IU/mL;
  3. Serum alanine aminotransferase (ALT) \> 2 times the upper limit of normal;
  4. No prior antiviral therapy prior to hospital admission.
