Background: There is a controversy about the relation between anti-hepatitis B (anti-HBs) antibody level and obesity. We designed this study to compare the vaccine efficacy in obese/overweight and non-obese cases. Methods: In this cross-sectional study, 242 obese/overweight and 85 non-obese individuals were participated. Cases were selected from a referral clinic for obesity and a referral hepa...

introduction and aims: in order to prevent liver cirrhosis and hepatocellular carcinoma in later life, it is essential to prevent hepatitis b virus (hbv) infection in infants. despite the availability of an effective vaccine, hepatitis b still continues to be a significant health problem. the aim of this study is to reveal the efficacy of passive and active immunoprophylaxis for preventing peri...

conclusions hbv vaccination in infancy is effective at preventing chronic hbv infection but is less effective at preventing occult hbv infection. similar studies examining the efficacy of adult hbv vaccination in preventing occult hbv have not been performed. this case highlights the importance of carefully determining the hbv status of high-risk individuals, as vaccination history and the pres...

BACKGROUND Tajikistan, considered highly endemic area for hepatitis B virus (HBV) in a pre-vaccine era, introduced hepatitis B vaccine in 2002 and reported ≥80% coverage with three doses of hepatitis B vaccine (HepB3) since 2004. However, the impact of vaccine introduction has not been assessed. METHODS We tested residual serum specimens from a 2010 national serosurvey for vaccine-preventable...

In order to evaluate the seroepidemiology and response to Butang vaccine in adolescents from low income families in Central Brazil, blood samples of 664 adolescents were tested for hepatitis B surface antigen (HBsAg), hepatitis B core antibody (anti-HBc), and hepatitis B surface antibody (anti-HBs) markers, and multiple logistical regression analysis was carried out to determine variables assoc...

Acute hepatitis A superimposed on chronic liver disease (CLD) has been associated with severe or fulminant hepatitis. An open, multicenter study was performed to compare the safety and immunogenicity of an inactivated hepatitis A vaccine in patients with CLD with that in healthy subjects. A secondary objective was to compare the safety of the hepatitis A vaccine with that of a commercial hepati...

conclusions this study shows lower anti-hbs among students who were vaccinated at infancy compared to those vaccinated at older childhood or adolescence. also, subsequent measurement of anti-hbs level at the time of entrance to university is recommended for all previously immunized students. results vaccination coverage rates were 74.1%. about half the participants didn’t show serological evide...

Hepatitis B antibody persistence was assessed in individuals who had previously received a vaccine booster. We measured hepatitis B surface antigen antibody (anti-HBs) levels 7 to 9 years post-hepatitis B booster in individuals with primary vaccination at birth. While 95 (91.3%) of 104 participants had detectable anti-HBs (minimum, 0.1 mIU/ml; maximum, 1,029 mIU/ml), only 43 (41%) had protectiv...
