Hepatitis B virus (HBV) is the leading cause of hepatocellular carcinoma (HCC) in places where chronic hepatitis B infection is endemic. Oral nucleos(t)ide analog (NA) therapy can reduce the risk of HCC, but cannot completely prevent its development. For HBV-related HCCs, viral inhibition by NAs can preserve or improve liver function, thereby increasing the chance of therapeutic intervention. A...

Abstract Background An estimated between 257 and 292 million people live with chronic HBV globally. While much is known about the causes, epidemiology of HBV, little understood quality life impact on those living infection. Methods A random sample HBV-related email queries sent to Hepatitis B Foundation, a U.S.-based non-profit organization, over 12-month period in 2018–2019 were retrieved, tab...

Due to the low viral load of hepatitis B virus (HBV) in plasma samples, conventional techniques have limitations to the detection of antiviral resistance mutations. To solve the problem, we developed a fast, highly sensitive, and accurate method to sequence the HBV whole-genome sequencing in plasma samples which had various viral loads from very low to high.Twenty-one plasma samples were collec...

BACKGROUND Maternal-infant transmission of hepatitis B virus(HBV) occurs even after passive-active immunization. Some scholars speculate that in-utero infection may be the main cause of immunoprophylaxis failure. However, there is a lack of evidence about the possible occurrence periods of perinatal transmission. METHODS From 2008 to 2012, 428 pairs of HBsAg-positive mothers and neonates were...

BACKGROUND Fresh-frozen plasma (FFP) may contain antibodies to hepatitis B surface antigen (HBsAg, anti-HBs). These anti-HBs may lead to a misinterpretation of the actual hepatitis B immune status. Furthermore, they may not only confer protection against hepatitis B virus (HBV), but may also favor the selection of HBsAg mutants. CASE REPORT We report a case of de novo HBV infection in a HBV-n...

H B virus (HBV) infection has been shown to induce several extra-hepatic lesions, especially through deposition of immune complexes in different organs (1-5). The exact mechanisms through which certain patients with chronic HBV infection develop glomerulonephritis are not well understood. However, several reports have suggested a role for hepatitis B surface antigen (HBsAg). The diagnosis of HB...

We aimed to investigate the impact of hepatitis B virus (HBV) DNA on the development of hepatocellular carcinoma (HCC). We conducted a case/control study based on 506 chronic HBV patients followed up since 1997. Forty-one patients developed HCC, and each of them was age and gender matched with two simultaneously recruited controls without HCC. HBV DNA was measured at the initial visit, at yearl...

CONTEXT There is a need to study potential infective etiologies in lymphomas. Lymphocyte-transforming viruses can directly infect lymphocytes, disrupt normal cell functions, and promote cell division. Epstein-Barr virus (EBV) is known to be associated with several lymphomas, especially Hodgkin lymphomas (HLs). And recently, the lymphocyte-transforming role of hepatitis B virus (HBV) has been em...

Integrins are a large family of cell surface receptors that bind extracellular matrix proteins and participate in cancer progression. However, the prognostic value of integrin family genes in post-operative patients with HBV-related hepatocellular carcinoma (HCC) remains unknown. In this study, we investigated 18 single nucleotide polymorphisms (SNPs) in integrin family genes and found that the...

A novel hepatitis B virus (HBV) variant was detected in the sera of two children in The Gambia, West Africa. The children had been immunized with plasma-derived vaccine and had developed antibody titres of 1448 international units x 10(-3) (mIU)/ml and 133 mIU/ml respectively against the hepatitis B surface antigen (HBsAg). Despite the protective levels of antibodies, HBV DNA was subsequently d...
