Hepatitis B virus infection (HBV) with undetectable levels of HBsAg, has been named occult HBV infection and observed in immunosuppressed patients. The aim of this study was to determine the frequency of occult HBV infection in patients with HIV from the West of México, using a combination of serological markers and nPCR. Thirty eight HIV/AIDS patients, 32 men (84.2%) and 6 (5.8%) women, withou...

Hepatitis B virus (HBV) infection is a major cause of chronic liver diseases that may progress to liver cirrhosis and hepatocellular carcinoma. Host immune responses are important factors that determine whether HBV infection is cleared or persists. After infection, viral replication occurs inside hepatocytes, and the secretion of infectious virions can take place at high rates for decades. Cons...

AIM To describe the characteristics of people diagnosed with acute and chronic hepatitis B virus (HBV) infection in British Columbia (BC). METHODS We used data from the BC Hepatitis Testers Cohort (BC-HTC), which includes all individuals tested for hepatitis C virus (HCV) or human immunodeficiency virus (HIV) or those diagnosed with HBV or active tuberculosis in BC since 1990. These data were...

The effect of hepatitis B virus (HBV) infection on bone mineral density in patients without advanced liver disease remains unclear. Hence, we assessed the association between HBV infection and the risk of osteoporosis. From 2000 to 2011, patients older than 20 years with HBV infection were identified from the Longitudinal Health Insurance Database 2000. Of the 180,730 sampled patients, 36,146 a...

PURPOSE To assess knowledge and attitude toward hepatitis B virus (HBV) infection among Korean immigrants in two cities in the Rocky Mountain region and to determine whether sociodemographic and cultural factors are related to the level of HBV knowledge. METHODS Community-based participatory study was conducted in five Korean churches in the Rocky Mountain region to develop baseline data on H...

Recovery from an acute hepatitis B virus (HBV) infection is associated with loss of HBV DNA from serum, hepatitis B e antigen seroconversion, hepatitis B surface antigen (HBsAg) seroconversion, and normalization of serum aminotransferases. These changes generally imply clearance of virus, but clinical observations have shown that reactivation of HBV infection can occur either spontaneously or a...

background : drug injection is one of the most significant risk factors for viral hepatitis and human immunodeficiency virus (hiv) infection. the present study was performed to evaluate the frequency of hepatitis b (hbv) and hiv infection in idus and to identify the risk factors of these infections in this group in a central city of iran, shahre-kord. methods : this study was conducted in 2004 ...

background hepatitis b virus (hbv) infection is a serious public health problem in china and worldwide. mother-to-child transmission is one of hbv’s main transmission routes in highly endemic regions. genome-wide association studies (gwas) identify single nucleotide polymorphisms (snps) at hla loci as associated with hbv infection. however, the mechanisms of hbv perinatal transmission and break...

Hepatitis B virus (HBV) covalently closed circular (CCC) DNA is the source of HBV transcripts and persistence in chronically infected patients. The novel aspect of this study was to determine the effect of RNA interference (RNAi) on HBV CCC DNA when administered prior to establishment of HBV replication or during chronic HBV infection. HBV replication was initiated in HepG2 cells by transductio...

background: hepatitis b virus (hbv) infection causes chronic infection in human population, with high mortality. one of the high risk communities is mentally retarded children, who are institutionalized. special conditions in these centers predispose children for hbv infection and transmission to healthy people. in this study our objective was to determine the prevalence of hbv infection among ...
