Occult hepatitis B virus infection

Journal of Hepatology, 2007
The persistence of hepatitis B virus (HBV) genomes in HBV surface antigen (HBsAg) negative individuals is termed occult HBV infection. Occult HBV status is associated in some cases with mutant viruses undetectable by HBsAg assays, but more frequently it is due to a strong suppression of viral replication and gene expression.

Occult Hepatitis B Infection

2021
Occult hepatitis B virus infection (OBI) is defined as the presence of HBV replicative templates in the liver with/without circulating HBV DNA in patients with undetectable hepatitis B surface antigen (HBsAg). The prevalence of OBI is estimated to be ranging from

Occult hepatitis B virus infection

Digestive and Liver Disease, 2000
Many studies have shown that hepatitis B virus infection may also occur in hepatitis B surface antigen-negative patients. This occult infection has been identified both in patients with cryptogenic liver disease and in patients with hepatitis C virus-related chronic hepatitis, and much evidence suggests that it may be a risk factor of hepatocellular ...

Occult hepatitis B and HIV infection

European Journal of Gastroenterology & Hepatology, 2019
Introduction Occult hepatitis B virus (HBV) infection, so-called occult B infection (OBI), is defined by the recognition of HBV-DNA in the absence of serum hepatitis B surface antigen (HBsAg). The HBV-DNA genome in OBI is fully replication competent and produced in the liver, characteristically with low-level HBV-DNA ...

Occult hepatitis B virus infection

Transfusion Clinique et Biologique, 2004
The detection of HBV DNA without HBsAg with or without the presence of HBV antibodies outside the acute phase window period defines occult HBV infection. This condition has been described in hepatocellular carcinoma (HCC), chronic hepatitis B, healthy HBV carriage and recovered infection, chronic hepatitis C and individuals without serological markers ...

Occult Hepatitis B in HIV-Infected Patients

JAIDS Journal of Acquired Immune Deficiency Syndromes, 2004
Prevalence of hepatitis B virus (HBV) markers, including occult HBV, has not been described in diverse cohorts among HIV-infected patients. The objective of this study was to assess prevalence and significance of active and occult HBV infection in an HIV-positive US cohort. A random sample was taken from 2 prospective multicenter treatment intervention
