BACKGROUND Hepatitis B virus (HBV) genotypes have distinct geographical distributions and are associated with different clinical courses. HBV genotype G (HBV/G) is extremely rare among Human immunodeficiency virus (HIV) infected populations in Japan. Genetic analysis and clinical course of recombinant forms with HBV/G infection are seldom reported in the literature. CASE PRESENTATION A 36-yea...

BACKGROUND/AIMS Patients undergoing maintenance dialysis have an unsatisfactory response to vaccination, including to hepatitis B vaccine. A recombinant HB vaccine containing a new adjuvant system AS04 (HBV-AS04) has been recently developed; a few data exist on the immunogenicity and safety of HBV-AS04 among patients undergoing regular dialysis. All hepatitis B virus-seronegative patients with ...

BACKGROUND The detection of hepatitis B virus (HBV) in blood donors is achieved by screening for hepatitis B surface antigen (HBsAg) and for antibodies against hepatitis B core antigen (anti-HBc). However, donors who are positive for HBV DNA are currently not identified during the window period before seroconversion. The current use of nucleic acid testing for detection of the human immunodefic...

The hepatitis B virus (HBV) is an important international cause of infectious acute and chronic liver diseases. HBV vaccines were developed to combat the potential life-threatening effects of HBV infection. Published case histories, retrospective reviews and analyses of epidemiological data report on the onset of immune-mediated myelitis after recombinant HBV vaccination, mostly in adults with ...

background: the association between hepatitis b virus (hbv) mutations and hepatocarcinogenesis were reported in the literature. preference for g over c in the leading dna strand has been reported to account for the asymmetry in nucleotide (nt) composition. the aim of this study was to analyze the complete genome sequence and compositional asymmetry of hbv in different stages of hepatitis b. met...

The aim of this study was to determine the prevalence and the incidence of hepatitis B virus (HBV) among haemodialysis (HD) subjects and to evaluate whether testing for serological markers at the time of admission is suitable for HBV screening in this population. One hundred twenty-three patients belonging to two HD centres from São Paulo, Brazil, were tested prospectively. HBV DNA was detected...

CONTEXT After five decades of Hepatitis B Virus (HBV) vaccine discovery, HBV is still a major public health problem. Due to the high genetic diversity of HBV and selective pressure of the host immune system, intra-host evolution of this virus in different clinical manifestations is a hot topic of research. HBV infection causes a range of clinical manifestations from acute to chronic infection, ...

Background: The household transmission of hepatitis B virus (HBV) is a major health problem. High incidence of HBV infection is observed within the household contacts of HBV carriers. We aimed to evaluate serological markers of hepatitis B infection among family members of HBV carriers in Arak, central Iran. Methods<stron...

background: for healthcare workers, sometimes the conventional hepatitis-b virus (hbv) vaccination schedule might not provide seroconversion rapidly enough. the aim of this study was to compare the efficacy of conventional hbv vaccination with an accelerated schedule (days 0-1-21). normal 0 false false false en-us x-none ar-sa materials and methods: in this randomized clinical trial, 161 health...
