Primary Outcome Measures:
  • Epidemiological characteristics from hepatitis B patients who lost HBsAg related to treatment with nucleoside/nucleotide analogues [ Time Frame: 15 months ]
    Study the number of diferents virological, serological, clinical, histological, biochemical characteristics from hepatitis B patients who lost HBsAg related to treatment with nucleoside/nucleotide analogues.


Secondary Outcome Measures:
  • Epidemiological characteristics in case of suspension of treatment. [ Time Frame: 15 months ]
    Count the diferents characteristics virological, histological, serological, and the clinical course of this patients whom must to be suspended the treatment
