OBJECTIVE The study was designed to assess the hepatitis B virus (HBV) and hepatitis C virus (HCV) co-infection scenario among the human immunodeficiency virus (HIV) infected patients attending a tertiary healthcare unit in eastern India. Additionally, clinical and virological characterization of these viruses, prior to antiretroviral therapy (ART) initiation was also done for better understand...

In China, HIV-1-infected patients typically receive antiretroviral therapy (ART) that includes lamivudine (3TC) as a reverse-transcriptase inhibitor (RTI) (ART-3TC). Previous studies from certain developed countries have shown that, in ART-3TC, 3TC-resistant HBV progressively emerges at an annual rate of 15-20% in patients coinfected with HIV-1 and HBV. This scenario in China warrants investiga...

INTRODUCTION Occult hepatitis B virus (HBV) is defined by the presence of HBV DNA in patient sera in the absence of HBsAg. Occult HBV has been associated with hepatocellular carcinoma, reactivation during immune suppression, and transmission to others. While the hepatitis B vaccine is very effective at preventing chronic HBV infection, recent studies indicate it is less effective at preventing ...

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...

زمینه و هدف: ویروس هپاتیت B (HBV) شایع ترین علت بیماری کبدی حاد و مزمن در جهان به شمار می رود. در افراد ناقل HBV می بایست وضعیت تکثیر ویروسی با استفاده از مارکرهای مناسب از جمله HbeAg مورد بررسی قرار گیرد تا در صورت مثبت بودن و همچنین بالا بودن آنزیم های کبدی افراد مبتلا به هپاتیت مزمن شناسایی شده و سپس تحت درمان قرار گیرند. لذا این مطالعه با هدف تعیین فراوانی مارکر HBeAg و ارتباط آن با سطح ت...

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)...
