AIM To investigate the prevalence and virological characteristics of occult hepatitis B virus (HBV) infections in patients with hematological malignancies in South Egypt. METHODS Serum samples were collected from 165 patients with hematological malignancies to monitor titers of HBV DNA, hepatitis B surface antigen (HBsAg), and antibodies to HBV core (anti-HBc) and surface antigens. Serum samp...

background although certain hbv mutations are known to affect the expression of hepatitis e antigen, their association with hbv viral level or clinical outcomes is less clear. objectives we evaluated associations between different mutations in the basal core promoter (bcp) and pre-core (pc) regions of hbv genome and subsequent changes in hbv viral dna level over seven years in a population of u...

BACKGROUND The efficacy and safety evidence of bortezomib in multiple myeloma (MM) patients with hepatitis B is vacant. This study aimed to investigate the efficacy and safety of bortezomib in MM patients with hepatitis B in China. METHODS From 2006 to 2011, 739 newly diagnosed MM patients were screened for serum hepatitis B virus (HBV) biomarkers. HBV-infected patients were followed for HBV ...

BACKGROUND Hepatitis B Virus (HBV) causes acute and chronic liver disease worldwide. HBV has eight genotypes (A to H) which is the reflection of its genome with their characteristic geographical distribution. Each genotype could have different pathogenic and therapeutic characteristics. There have been few records on HBV genotyping in general population from our region. This study aimed to dete...

conclusions in conclusion, our observations indicated that pcdna3.1 (+)-hbv1.3c was superior to aav/hbv plasmid for establishment of persistent hbv infection by hi, in vivo, and this mouse model could be useful for studies of hepatitis virology and for the development of innovatory treatments for hbv infections. results in 60% of the mice injected with pcdna3.1 (+)-hbv1.3c, hbsag, hbeag, hbcag ...

Hepatitis B surface antigen (HBsAg) is regarded as sole marker of hepatitis B virus (HBV) infection in Bangladesh and most other developing countries. However, some HBV-negative subjects may harbor HBV DNA and transfusion of their blood may cause HBV infection in recipients. HBV DNA was checked in 20 patients with cryptogenic liver cirrhosis, 10 patients with hepatocellular carcinoma without an...

OBJECTIVE To evaluate the inhibiting effects of the root of Mallotus apelta (Lour.) Muell.-Arg. on duck hepatitis B virus (D-HBV) in vivo. METHODS Forty nestling ducks with congenitally infection of D-HBV detected by PCR were randomly divided into five groups: untreated group, lamivudine-treated group, and high-, medium- and low-dose root of Mallotus apelta-treated groups. The ducks in the la...

The hepatitis B virus (HBV) carrier rate has decreased in Japan; however, the incidence of HBV infection among hepatocellular carcinoma (HCC) patients has not decreased accordingly. In this study, we aimed to assess the time trends of the clinical characteristics in HCC patients with chronic HBV infection. Between 2000 and 2012, we enrolled a total of 156 HCC patients with chronic HBV infection...

results there were 64 women and 936 men in the population under study. the mean ± sd age of the donors was 38 ± 11 years. 80 out of 1000 samples (8%) were found to be positive for hbcab. hbv dna was detected in 50% of hbcab positive specimens. the mean ± sd age of donors without hbv dna was 37.7 ± 10.5 years and for donors with hbv dna was 40.9 ± 11.2 years (p = 0.05). objectives the aim of thi...

The objective of the present study was to evaluate the serum viral load in chronically infected Hepatitis B virus (HBV) patients and to investigate the distribution of HBV genotypes in São Paulo city. Quantitative HBV-DNA assays and HBV genotyping have gained importance for predicting HBV disease progression, have been employed for assessing infectivity, for treatment monitoring and for detecti...
