The use of livers from hepatitis B surface antigen-negative (HBsAg- )/hepatitis B core antibody-positive (HBcAb+ ) donors in liver transplantation (LT) for HBsAg(-) /HBcAb- recipients is still controversial because of a lack of standard antiviral prophylaxis and long-term follow-up. We present our 13-year experience with the use of HBcAb+ donor livers in HBcAb- recipients. Patients received pro...

BACKGROUND HBV reactivation is associated with high mortality rates in hematopoietic stem cell transplantation (HSCT) and prophylactic lamivudine (LMV) treatment is suggested to prevent this phenomenon. However, the duration of LMV treatment in HSCT patients is not fully defined and the time of immune recovery is considered the best parameter for a drug to be safely interrupted. In patients und...

Antiviral therapy using newer nucleos(t)ide analogues with lower resistance rates such as entecavir or tenofovir could suppress hepatitis B virus (HBV) replication, improve liver function, delay or obviate the need for liver transplantation in some patients, and reduce the risk of HBV recurrence. The combination of long-term antiviral and low-dose hepatitis B immune globulin (HBIG) can effectiv...

CASE REPORT A patient is described who developed hepatitis B virus (HBV) reinfection five months following liver transplantation. Failure of hepatitis B immunoglobulin prophylaxis was associated with the emergence of mutations. HBV gene sequencing identified nucleotide substitutions associated with amino acid changes, one within the major hydrophilic region (MHR) of the HBV surface antigen at a...

Hepatitis B virus (HBV) continues to be a worldwide public health concern. There are more than 240 million people with chronic infection across the globe and 780 000 deaths each year as a result of acute or chronic HBV. Infants born to mothers with chronic HBV infection are at very high risk of acquiring the virus and progressing to chronic infection. In the 1970s–1980s, HBV vaccine and high-ti...

Prophylactic antiviral therapy is essential for lymphoma patients with high baseline HBV DNA who undergo cytotoxic chemotherapy. However, there are limited data on the optimal options. The present study was designed to compare the efficacy of prophylactic lamivudine (LAM) with lamivudine plus adefovir dipivoxil (LAM+ADV) in preventing hepatitis B virus (HBV) reactivation in lymphoma with, pre-c...

PURPOSE Recently, a new enzyme immunoassay for the detection of hepatitis B virus (HBV) core-related antigen (HBcrAg) has been reported. In this study, we proposed to account for feasibility of HBcrAg assay, and discuss the dynamics of HBV seen in patients following HBV-related living donor liver transplantation (LDLT). METHODS AND RESULTS This study involved 12 patients; 11 patients had posi...

Viral reactivation in hepatitis B surface antigen (HBsAg) carriers undergoing immunosuppressive therapy is well documented. To evaluate the role of lamivudine prophylaxis in Hepatitis B virus (HBV) carriers treated with immunosuppression for nonhepatic disorders, we reviewed our experience between 1997 and 2000 at Hadassah University Hospital (Jerusalem, Israel). Controls were patients who were...

INTRODUCTION The effect of chronic hepatitis B virus (HBV) infection on pregnancy is not clear. Hepatitis B virus infection of newborns in the case of natural delivery occurs in 70-90% of cases. Risk factors of infection are the presence of serum HBeAg and HBV DNA level above 107 IU/ml. Active and passive prevention protect more than 95% of neonates born to mothers infected with HBV. The aim of...
