OBJECTIVE The reactivation of hepatitis B virus (HBV) infection is a well-known event in hepatitis B surface antigen (HbsAg)-positive patients receiving immunosuppressive therapy. The objective of this study was to assess the antiviral practice and course of HBV infection in inflammatory arthritis. MATERIAL AND METHODS Nineteen rheumatology centers participated in this retrospective study. Hb...

The mechanism responsible for hepatitis B virus (HBV) exacerbation during chemotherapy and radiotherapy remains unknown. We investigated whether the activation of DNA repair pathways influences HBV replication. The upregulation of the promyelocytic leukemia (PML) protein and its associated PML nuclear body (PML-NB) by chemotherapy and irradiation-induced DNA repair signaling correlated with the...

Spontaneous preterm birth is the leading cause of perinatal morbidity and mortality. In this study the spontaneous preterm birth rates in a group of hepatitis B e antigen (HBeAg)-negative chronic hepatitis B virus (HBV)-infected pregnant women without known risk factors for preterm delivery as well as the role of maternal laboratory data and hepatitis B surface antigen/HBV deoxyribonucleic acid...

Chronic hepatitis B virus (HBV) infection can lead to liver cirrhosis and hepatocellular carcinoma. HBV reactivation during or after chemotherapy is a potentially fatal complication for cancer patients with chronic HBV infection. Transcription of HBV is a critical intermediate step of the HBV life cycle. However, factors controlling HBV transcription remain largely unknown. Here, we found that ...

We read with interest the editorial on the correlation between hepatitis B virus (HBV) genotypes and outcome of HBV infection by Fung and Lok.1 This article made a succinct outline of the epidemiology of HBV genotypes and their association with hepatitis B e antigen seroconversion, activity of liver disease, and response to treatment. We believe that this article will be helpful to hepatologist...

(2)-b-2*,3*-Dideoxy-3*-thiacytidine (lamivudine [3TC]) is a nucleoside analog which effectively interferes with the replication of hepatitis B virus (HBV) DNA in vitro and in vivo. We have investigated the antiviral properties of 3TC in vitro in HepG2 cells infected with recombinant HBV baculovirus. Different types of information can be obtained with the HBV baculovirus-HepG2 system because (i)...

Hepatitis D virus (HDV) infection causes a severe chronic viral hepatitis with accelerated development of liver cirrhosis and decompensation, but whether it further increases the risk hepatocellular carcinoma (HCC) is unclear. We performed comprehensive systematic review published literature meta-analysis to assess HCC in HDV B (HBV) co-infected, compared HBV mono-infected patients. The study w...

Hepatitis B virus (HBV) infection remains a major public health problem worldwide with more than 240 million individuals chronically infected. Current treatments can control HBV replication to a large extent, but cannot eliminate HBV infection. Cytokines have been shown to control HBV replication and contribute to HBV cure in different models. Cytokines play an important role in limiting acute ...

BACKGROUND Tenofovir (TDF) is effective for treatment of hepatitis B virus (HBV) in human immunodeficiency virus (HIV) infection; however, some individuals have ongoing HBV viremia, the reasons for which are unclear. We determined the patterns and factors associated with detectable HBV DNA in HIV-HBV-coinfected subjects on highly active antiretroviral therapy (HAART). METHODS One hundred sixt...

BACKGROUND Sub-Saharan Africa carries a high burden of co-infection with HIV-1 and hepatitis B virus (HBV). In this region, individuals with HIV-1/HBV co-infection on antiretroviral therapy (ART) frequently receive lamivudine as the only agent active against HBV, raising concerns for development of HBV resistance to lamivudine. We aimed to determine the prevalence, clinical, and virologic outco...
