This study aimed to investigate the virological status in liver (both tumor and adjacent non-tumor tissue), the clinical features and the contribution of occult HBV infection (OBI) to postoperative prognosis in HBeAg-negative(-) hepatocellular carcinoma (HCC) patients in China. Using quantitative TaqMan fluorescent real-time PCR assays, HBV covalently closed circular DNA (cccDNA) and total DNA ...
INTRODUCTION Despite significant improvement in Anti-HBV vaccination and treatment, HBV infection continues to be a major global health problem. It has been reported that as much as 350 million carriers exist in the world and about one million of them will die annually (1). The prevalence of HBV infection in Iran ranged between 2.7 to 7.2 %, which declined below 2% following national vaccinatio...
BACKGROUND Hepatitis B virus (HBV) and tuberculosis (TB) represent major public health problems. There is currently little data on HBV infection among TB patients with and without human immunodeficiency virus (HIV). OBJECTIVES To assess HBV prevalence among TB patients with and without HIV. STUDY DESIGN From April 2008 to March 2010, a cross-sectional study was conduct among TB patients att...
OBJECTIVE As sub-Saharan Africa is highly endemic for hepatitis B virus (HBV) and human immunodeficiency virus (HIV) infections, and their co-infection requires special management, we aimed to assess the serological and molecular characteristics of HBV in patients with AIDS. DESIGN This was a cross-sectional, case control study, which enrolled 200 patients with AIDS and 200 HIV-negative contr...
During previous studies of susceptibility to hepatitis B virus (HBV) infection, HBV DNA was detected in 2/6 wild-caught baboons. In the present study, HBV DNA was amplified from 15/69 wild-caught baboons. All animals were negative for HBV surface antigen and antibody against HBV core antigen. Liver tissue from 1 baboon was immunohistochemically negative for HBV surface antigen but positive for ...
Background: The outcome of Hepatitis B virus (HBV) infection is chronic or resolved HBV infection. Over the time, the levels of HBsAg or Anti-HBs declined and were not detectable in their sera and was named as isolated anti-HBc. The purpose of this study was to assess the prevalence of isolated anti-HBc in previously HBV infected individuals.Methods: From April 2000 to September 2008, the resul...
Background Croatia implemented individual donation (ID)-NAT testing of blood donors in 2013 for three viruses HBV, HCV, and HIV-1 as a mandatory test for all blood donors. This study assessed the impact of NAT screening 3 years after its implementation. Methods A total of 545,463 donations were collected and screened for HBV, HCV, and HIV-1 using the Procleix Ultrio Plus Assay. All initially ...
Hepatitis B virus (HBV) and hepatitis C virus (HCV) share modes of transmission and their combined infection is a fairly frequent occurrence particularly in areas where the two viruses are endemic and among subjects with a high risk of parenteral infections. Moreover, the number of coinfected patients is likely higher than is usually thought. In fact, many studies have shown that HBV genomes ma...
A 68-year-old man with occult hepatitis B virus (HBV) infection was diagnosed with malignant lymphoma and achieved complete remission after treatment with a chemotherapy regimen including rituximab for 5 months. Entecavir (ETV) was also used during and after chemotherapy and was ended at 14 months after chemotherapy. However, reactivation of HBV was observed in blood tests, which showed not onl...
Today, the increased life expectancy of chronic dialysis patients allows HBV to manifest all biological effects it can produce: asymptomatic antigenaemia, cirrhosis, hepatocellular carcinoma and viral reactivation post-renal transplant immunosuppressive therapies. Recently, some studies reported occult HBV infection in haemodialysis patients [4,5]. We would like to communicate our experience ab...
