Childhood Hepatitis B virus (HBV) infection causes both medical and public health challenges. Infants who acquire HBV parentally have up to 90% risk of developing chronic HBV infection. It is now estimated that approximately 10% of worldwide cancers are attributable to viral infection, with the vast majority (>85 %) occurring in the developing world. In this distribution, elevated rate and prev...

background occult hepatitis b virus infection (obi) is defined as the presence of hepatitis b virus (hbv) dna in the liver and/or in the serum of patients with negative results of hepatitis b s antigen (hbsag) test with or without serological markers of previous viral exposure. the impact of obi in patients with chronic hepatitis c (chc) is still unclear. objectives the aim of this study was to...

hepatitis delta virus (hdv) infection results in more severe and even fulminant form of hepatitis b in co-infected cases. this study was designed to estimate the prevalence of anti-hdv positivity and the associated risk factors in patients with chronic hepatitis b virus infection in zahedan (iran). in this cross-sectional study a total of 440 consecutive patients with chronic hepatitis b virus ...

Potent antivirals are used for the treatment of hepatitis B infection. A 38-year-old female patient whose hepatit virus (HBV) viral load was suppressed under tenofovir disoproxil fumarate but had a flare during in vitro fertilization (IVF) is presented. Although HBV DNA negative continuously controls, an increase observed IVF treatment. Hepatitis has been isolated from many extrahepatic tissues...

Co infection with hepatitis C virus and hepatitis D virus (HDV) is less common than that with HIV and HCV, although more attention has been given to HCV co infection as a result of its higher frequency of chronic disease. The present investigation was attempted to determine the exact prevalence of hepatitis B virus (HBV), hepatitis C virus (HCV) and hepatitis D virus (HDV) infection among liver...

Non-Hodgkin lymphoma (NHL) ranked as the sixth most common cancer in 2016. Its incidence has steadily increased in the past decade. Both environmental and genetic factors can promote the development of NHL. It has been hypothesized that chronic antigenic stimulation, especially due to a virus such as the human immunodeficiency virus, Epstein-Barr virus and hepatitis C virus (HCV), plays an impo...

INTRODUCTION Hepatitis B virus (HBV) infection is a serious public health issue worldwide. Hepatitis B virus is classified into eight genotypes, varying from A to H, with distinct geographical distributions. In Brazil, the most frequent genotypes are A, D, and F. METHODS This study aimed to characterize the HBV genotypes in cases of hepatitis B virus and hepatitis D virus (HDV) co-infections ...

Diverse Indian population provides an excellent opportunity to study the prevalence and feature of hepatitis virus for understanding viral evaluation and viral pathogenesis. India is in intermediate zone of pathogenesis of hepatitis B (2-5%), and India is having around 40 million hepatitis B virus (HBV) carriers. A wide variation in prevalence of hepatitis B is observed from region to region an...

The competence of non-hepatocytes to support hepatitis B virus (HBV) gene expression and replication was studied by transient transfection of various human cell lines with a head-to-tail dimer of HBV DNA. Independent of their neuroectodermal, mesenchymal or epithelial origin, all non-hepatocyte cell lines tested synthesized and secreted hepatitis B surface antigen (HBsAg) and hepatitis B core/e...

background: in spite of available, and sensitive screening assay for detection of hepatitis b virus surface antigen (hbsag), occasional cases of post-transfusion hepatitis b virus infection are still observed. the aim of the present study was to assess the prevalence of positive anti hepatitis b core (anti-hbc) and presence of hbv-dna in serum sample of healthy blood donors negative for both hb...
