A 2010 update on occult hepatitis B infection
Pathologie Biologie, 2010Occult hepatitis B virus infection is a challenging issue whose virological and clinical relevance has been a source of long-lasting debate. By definition, OBI is characterized by the persistence of HBV-DNA in the liver tissue (and in some cases also in the serum) in absence of HBsAg.

Occult hepatitis B virus and hepatitis C virus infections
Reviews in Medical Virology, 2008AbstractOccult HBV infection is a well‐recognised clinical entity characterised by the detection of HBV‐DNA in serum and/or in liver in the absence of detectable hepatitis B surface antigen (HBsAg). Occult HBV infection has been described not only in patients who have resolved an acute or chronic HBV infection but also in patients without any ...

Occult Hepatitis B Infection in Recent Immigrants to Italy: Occult B Infection in Immigrants
Journal of Community Health, 2019This study determined the prevalence and clinical features of occult hepatitis B infection (OBI) in a population of recent immigrants to Italy. Two hundred-five immigrants were tested for HBV-infection and were classified as seropositive-OBI or false-OBI.

Occult hepatitis B virus infection with positive hepatitis B e antigen
Clinica Chimica Acta, 2015Hepatitis B e antigen (HBeAg) is a marker to indicate active replication of hepatitis B virus (HBV). Occult HBV infection (OBI), referred to persistence of HBV DNA in serum and/or liver without detectable serum hepatitis B surface (HBsAg), usually has low HBV DNA levels.

Occult hepatitis B infection is a unique disease entity defined by detectable hepatitis B virus DNA in the sera and/or livers in subjects who are negative for HBsAg. OBI can be classified by serology. It can also be classified according to the medical history of the subjects.

Occult Hepatitis B Virus Infection: Detection and Significance
Digestive Diseases, 2010The Taormina Consensus Conference defined ‘occult hepatitis B virus (HBV) infection’ (OBI) as the ‘presence of HBV DNA in the liver of individuals testing HBsAg-negative with currently available assays’. Most occult is the so-called ‘window period’ after exposure before HBV DNA appears in the blood. We identified two blood donors whose donations tested

Occult hepatitis B virus infection: implications in transfusion
Vox Sanguinis, 2004Hepatitis B virus (HBV) presents a higher residual risk of transmission by transfusion than hepatitis C virus (HCV) or human immunodeficiency virus (HIV). While most infectious blood units are removed by screening for hepatitis B surface antigen (HBsAg), there is clear evidence that transmission by HBsAg‐negative components occurs, in part, during the ...

Occult hepatitis B virus infection in hepatitis B vaccinated children in Taiwan
Journal of Hepatology, 2009Presence of occult HBV infection in HBV vaccinated children remains largely unknown. The aim of this study was to investigate the prevalence of occult HBV infection among HBV vaccinated children in Taiwan.Forty-six HBsAg negative sera from vaccinated children were enrolled randomly.

[Occult hepatitis B virus infection].
Virologie (Montrouge, France)Occult hepatitis B virus (HBV) infection is a peculiar form of chronic viral infection identified since the early 80's and can be defined as the presence of HBV DNA in the serum and/or in the liver tissue of patients negative for the HBV surface antigen (HBsAg) using usual serological tests.
