Brief Summary:
This is a prospective, multicentre observational follow-up study of PegIFN treatment unstained response in nucleoside experienced patients with Chronic Hepatitis B.Patients will join this study after finished following clinical trail about A Study of Combination or Sequential Treatment With PEGASYS (Peginterferon Alfa-2a) and Entecavir in Patients With HBeAg Positive Chronic Hepatitis B(OSST trail),A Real-World Study of Pegylated Interferon In Nucleoside-treated Patients With Chronic Hepatitis B (COST study), Combination Therapy With Interferon Plus Interleukin 2 and Hepatitis B Vaccine in Chronic Hepatitis B Patients(Endeavor study),A Prospective Clinical Trial in Chronic Hepatitis B Patients Nucleotide Analogues Experienced (Anchor A Study),Sequential/Combination Therapy in Nucleoside or Nucleotide Analogue (NA)-Suppressed Chronic Hepatitis B Patients (NPGV study).We plan to compare the HBsAg negative rate and maintenance rate,the occurrence of liver cirrhosis and the occurrence rate of hepatocellular carcinoma(HCC) related to hepatitis B virus(HBV) within five years between interferon group (including interferon alone or interferon combined with other drugs) and nucleoside analogues.Patients were divided into two groups based on whether they received interferon or not.

Condition or disease
Hepatitis B, Chronic

Detailed Description:
Patients who treated with nucleoside analogs, and previously took part in the OSST,COST,Endeavor, Anchor NPGV studies, were included in the observational study after they finished. The patients entered the following two observation groups based on previous studies: Group A: formerly interferon group (including interferon alone or interferon combined with other drugs); Group B: formerly nucleoside analogue treatment group. Each group was followed for five years.All patients were followed up for physical examination (vital signs, whole body examination) and laboratory assessment (HBsAg quantification, HBeAg quantification, HBV DNA, HBV immunology marker, blood routine, blood biochemistry, alpha fetoprotein, Fibroscan, liver Doppler) in every six month.

Study Description Study Design Groups and Cohorts Outcome Measures Eligibility Criteria Contacts and Locations More Information

Primary Outcome Measures :
  1. The rate of HBsAg negative at week 260 [ Time Frame: week 260 ]
    Compare the HBsAg negative rate at week 260 with that at baseline


Secondary Outcome Measures :
  1. The maintenance response rate of HBsAg negativity at week 260 [ Time Frame: week 260 ]
    the proportion of patients with sustained HBsAg negativity at week 260 among the patients whose HBsAg negative at baseline

  2. HBsAg quantification decline from baseline to week 260 [ Time Frame: week 260 ]
    HBsAg quantification decline from baseline to week 260 are measured.

  3. Change from baseline in HBsAg seroconversion at week 260 [ Time Frame: week 260 ]
    HBsAg seroconversion from baseline is measured

  4. The rate of HBsAb positive at week 260 [ Time Frame: week 260 ]
    Compare the rate of HBsAb positive at week 260 with that at baseline

  5. Measure the Fibroscan value [ Time Frame: week 260 ]
    Fibroscan value from baseline is measured

  6. the occurrence rate of liver cirrhosis [ Time Frame: week 260 ]
    Statistics for occurrence rates of liver cirrhosis

  7. the occurrence rate of HCC related to HBV [ Time Frame: week 260 ]
