OBJECTIVE To evaluate the effectiveness of a recombinant hepatitis B vaccine used in endemic areas of Colombia, as well as risk factors associated with hepatitis B virus (HBV) infection and carriage after vaccine introduction. METHODS A cross-sectional study was carried out in urban and rural areas of the Colombian Amazon, a highly endemic area for hepatitis B infection. Children under 12 yea...

Neonates of hepatitis B surface antigen (HBsAg) positive and hepatitis B encoded antigen (HBeAg) positive mothers received 10 micrograms of recombinant hepatitis B vaccine at months 0, 1, 6, or 0, 1, 2, 12, with or without immunoglobulin at birth, and were followed up to the age of 8 years for HBsAg, anti-HBc, and anti-HBs. Some were boosted at month 60. The overall vaccine protection at month ...

As hepatitis B and C share modes of transmission, their combined occurrence is not uncommon, particularly in areas where both viruses are endemic and in individuals at high-risk of parenteral infection. Both viral hepatitis infections form an important global public health problem, responsible for over half a billion chronic infections worldwide. Their distinctive characteristics impact upon th...

Background: Hepatitis B (HB) vaccination is a recommended procedure in all dialysis patients, but its efficacy has not been perfect. In the current study, we aimed to conduct a comprehensive review of the literature to find and pool data of the randomized trials evaluating the impact of serum albumin levels on the immunogenicity of HB vaccination in dialysis patients. Methods: Literature searc...

Background: Due to their similar routes of transmission, human immunodeficiency virus (HIV) and hepatitis B virus (HBV) co-infection occurs considerably. HBV infection progresses more rapidly in HIV-infected patients. Therefore, HBV vaccination of all non-immune HIV infected patients is recommended. On the other hand, HIV-infected subjects have suboptimal responses to HBV vaccine. In this study...

Women (175) who participated in an in vitro fertilization (IVF) programme were possibly exposed to hepatitis B virus. Later it became evident that 79 women had a hepatitis B infection, 49 were exposed but not infected and 47 were not exposed. Hepatitis B immunoglobulin (HBIg) and recombinant hepatitis B vaccine (HBvaxDNA) were offered to all women and partners except for those with established ...

BACKGROUND A gap exists in the literature on celiac disease populations and the response to hepatitis B vaccination. OBJECTIVE To identify pediatric patients with celiac disease who received the primary hepatitis B vaccination and investigate their response to vaccine. DESIGN/METHODS Patients underwent blood draw for hepatitis B surface antibody titers. Patients with undetectable or non-pro...
