Brief Summary

Background Hepatitis B virus (HBV) co-infection in individuals with hepatitis C virus (HCV) can enhance the severity of hepatitis and the risks of liver cirrhosis and hepatocellular carcinoma (HCC). Hepatitis B vaccine is an effective measure to prevent HBV infection. Whether patients with HCV infection have non-protective antibody responses to hepatitis B vaccination more frequently than healthy subjects is still controversial and studies about cytokine response have been seldom reported. Methods Not-in-treatment patients with chronic HCV infection and 1:2 community/gender matched healthy control were obtained from a community-based screening. All participants received three doses of hepatitis B vaccine (20 μg HBsAg/ml/dose) on 0, 1 and 6 months schedule. Anti-HBs was tested 1 month after the third dose of vaccination and was compared between two groups. Spot-forming cells (SFCs) of interferon-γ (IFN-γ), interleukin-2 (IL-2), interleukin-4 (IL-4), interleukin-5 (IL-5) and interleukin-6 (IL-6) produced by lymphocyte were tested by enzyme-linked immunospot (ELISPOT) and were compared between two groups.

Outcome Measures

Primary Outcomes (1)

  • Antibody to the hepatitis B surface antigen response and cytokine response to hepatitis B vaccination in patients with chronic HCV.

    Three doses of hepatitis B vaccine made by Recombinant DNA Techniques in Saccharomyces Cerevisiae (20 μg HBsAg/1.0ml per dose, Shenzhen Kangtai Biological Products Co., Ltd., Shenzhen, Guangdong Province, China) were given intramuscularly in the deltoid region to all participants at 0, 1 and 6 months respectively. Blood samples from the participants were collected one month after the third dose of vaccination. Anti-HBs was assayed by Abbott Chemiluminesent Microparticle ImmunoAssay (CMIA) (Abbott Ireland Diagnostics Division, Sligo, Ireland) one month after the first and the third dose of vaccination. Spot-forming Cells (SFCs) were enumerated with ImmunoSpotTM system (Cellular Technology Ltd.). Differences between HCV group and healthy control group in anti-HBs and immunodotting spots were examined.

Secondary Outcomes (1)

  • The occurrence and severity of solicited local reactions at the injection site, solicited systemic reactions, and any unsolicited adverse after hepatitis B vaccination in patients with chronic HCV

    from the first dose of vaccination to one month after the third dose of vaccination
