Study Description
Brief Summary:
The purpose of this study is to investigate the efficacy and safety of medical ozone in treatment of chronic hepatitis B patients.

Condition or disease Intervention/treatment Phase
Chronic Hepatitis B Device: medical ozone therapy with humares Drug: conventional interferon-α Phase 4

Detailed Description:
Total of 439 patients with chronic hepatitis B were divided according to patients' intention into two arms. 173 patients in arm I were treated with medical ozone therapy with humares which was made in Germany for at least 12 weeks.266 patients in arm II were treated with conventional interferon-α for at least 24 weeks.Patients in both groups were followed-up for 24 weeks.Virology response, biochemistry response and hepatitis B viral serological response will be studied at 12 weeks after the treatment, at the end of treatment and after 24 weeks of follow-up.

Arms and Interventions

Arm Intervention/treatment
Experimental: medical ozone therapy with humares Device: medical ozone therapy with humares
Medical ozone therapy with instrument made in Germany Patients in this group will receive autohemotherapy treatment. First month: ozone concentration: 20µg ~40µg /ml;The second month: 30µg/ml × 100ml oxygen- ozone gas × 100 ml blood;The third month: 20µg/ml × 100ml oxygen- ozone gas× 100 ml blood.
Other Name: ozone instrument made in Germany: Humares
Active Comparator: conventional interferon-α Drug: conventional interferon-α
Patients in the conventional interferon-α treatment group received subcutaneouslly injection of 5 million units of conventional interferon-α in three times per week for at least 24 weeks.

Outcome Measures

Primary Outcome Measures :
  1. HBV DNA [ Time Frame: up to 77 weeks ]
    To demonstrate the percentage of patients achieving HBV DNA<1000copies/mL

Secondary Outcome Measures :
  1. HBeAg [ Time Frame: up to 77 weeks ]
    Percentage of patients with HBeAg loss and HBeAg seroconversion in patients with HBeAg positive at baseline.
