BACKGROUND Vaccinating infants against hepatitis B virus (HBV) is the most effective way of preventing the disease. However, since HBV exposure can increase during adolescence, it is essential that antibody persistence is maintained. We evaluated the antibody persistence and immune memory against hepatitis B, in 12-13 y olds who had received complete primary + booster vaccination with diphtheri...

BACKGROUND Conventional hepatitis B virus (HBV) vaccination fails to achieve efficient protection in about 5-10% of the world population. Hence, different strategies have been adopted to ameliorate HBV antibody titers. This study aimed to evaluate the concurrent application of tetanus-diphtheria (Td) and HBV vaccination on hepatitis B surface (HBs) antibody titer in low-responder healthy indivi...

Hepatitis B Virus (HBV) leads to a number of hepatic complications, from acute to chronic hepatitis, cirrhosis and hepatocellular carcinoma, is a well-established fact. Upcoming clinical research, over the years, associates numerous extrahepatic manifestations during the acute and chronic episodes of hepatitis B with significant morbidity and mortality. A causal relationship between HBV and ser...

Introduction: Hepatitis B is a disease caused by the hepatitis B virus (HBV), which is transmitted through percutaneous (i.e., puncture through the skin) or mucosal (i.e., direct contact with mucous membranes) exposure to infectious blood or body fluids. HBV can cause chronic infection, resulting in cirrhosis of the liver, liver cancer, liver failure, and death. Persons with chronic infection a...

Hepatitis B and C often progress to decompensated liver cirrhosis requiring orthotopic liver transplantation (OLT). After OLT, hepatitis B recurrence is clinically controlled with a combination of hepatitis B immunoglobulin (HBIG) and nucleos(t)ide analogues. Another approach is to induce self-producing anti-hepatitis B virus (HBV) antibodies using a HBV envelope antigen vaccine. Patients who h...

The aim of this study was to examine the efficacy of combined immunization of hepatitis B immunoglobulin (HBIG) and hepatitis B vaccine (HBVac) in blocking father-infant transmission of hepatitis B virus (HBV). Newborns positive at birth for blood HBV sur-face antigen (HBsAg) and/or HBV DNA were selected and immunized with HBIG combination HBVac. At 7 months, HBV markers and HBV DNA of each neo...

Coinfection of hepatitis B virus (HBV) with hepatitis C virus (HCV) is quite common, leading to an increase in morbidity and mortality. As such, HBV vaccination is recommended in HCV-infected individuals. However, HBV vaccine responses in HCV-infected individuals are often blunted compared with uninfected populations. The mechanism for this failure of vaccine response in HCV-infected subjects r...

Abstract Background Hepatitis B virus (HBV) vaccine seroprotection rates with conventional aluminum adjuvanted recombinant HBV vaccines (HepB-alum) among people HIV (PWH) are varied. HepB-CpG, a novel vaccine, has shown higher in immunocompetent patients but is not well studied PWH. There no published studies comparing between HepB-alum and HepB-CpG The purpose of this study was to evaluate com...

background: hepatitis b virus (hbv) vaccination is a well-known, safe and effective way for protection against hbv infection; however, non-responders remain susceptible to infection with hbv. this is so important in patients with any kind of chronic liver disease, especially chronic hepatitis c virus (hcv) patients in whom acute hbv infection may lead to decompensation of liver disease. some of...

Protective measures against occupational exposure to the hepatitis B virus (HBV) and hepatitis C virus (HCV) must be taken in order to prevent infection in dental care workers. To determine the best way to protect these workers, our study examined viral hepatitis infection in dental care workers in regions with a high prevalence of HCV infections in Japan. In total, 141 dental care workers (inc...
