Brief Summary:
Collect basic information of patients before antiviral treatment and when HBsAg disappears, and divide them into three groups A, B, and C based on baseline anti HBs titers after informed consent. During the follow-up period of all patients, clinical biochemistry, virology (HBVDNA, HBVRNA), serological indicators (HBsAg, anti HBs, HBeAg, anti HBe, HBcrAg, anti HBc), AFP, Fibroscan, liver imaging examinations will be conducted every 3-6 months, and blood samples will be retained for monitoring the frequency of immune cells (pDC, Treg) and the expression of functional molecules, as well as cytokines (IFN - γ, IP-10, IL-10, and TGF - β). Observe the sustained response rate and recurrence rate of virological and serological indicators, as well as the incidence of hepatitis and liver cancer during the follow-up period.
Detailed Description:
Collect basic information of patients before antiviral treatment and when HBsAg disappears, and divide them into three groups A, B, and C based on baseline anti HBs titers after informed consent. Group A has an anti HBs titer ≥ 100mIU/ml and is followed up every 3-6 months for observation. The anti HBs titers\<100mIU/ml were randomly divided into two groups: Group B and Group C. Group B did not intervene and was followed up every 3-6 months for observation; In group C, 20 micrograms of recombinant hepatitis B vaccine were injected subcutaneously three times on day 0, January and March. For group C patients, the level of anti HBs was detected at the 4th month after the initial vaccination. For those who could not produce anti HBs (anti HBs\<10mIU/ml), the recombinant hepatitis B vaccine was subcutaneously injected three times, 20 μ g each time, in 0 day, January and March. During the follow-up period of all patients, clinical biochemistry, virology (HBVDNA, HBVRNA), serological indicators (HBsAg, anti HBs, HBeAg, anti HBe, HBcrAg, anti HBc), AFP, Fibroscan, liver imaging examinations were conducted every 3-6 months, and blood samples were retained for monitoring the frequency of immune cells (pDC, Treg) and the expression of functional molecules, as well as cytokines (IFN - γ, IP-10, IL-10, and TGF - β). Observe the sustained response rate and recurrence rate of virological and serological indicators, as well as the incidence of hepatitis and liver cancer during the follow-up period.
