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.
one month after the third dose of vaccination
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
Study Arms (2)
HCV group
EXPERIMENTALThree 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.
Healthy control group
ACTIVE COMPARATORThree 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.
