Occult hepatitis B virus infection in patients with leprosy

Journal of Medical Virology, 2018
Leprosy patients may present with immune system impairment and have a higher hepatitis B virus (HBV) seroprevalence, justifying the investigation of occult HBV infection in these individuals. The aim of this study was to verify the frequency and the clinical factors associated with occult HBV infection in leprosy patients.

Occult Hepatitis B Infection

2017
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, 2010
The 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 with positive hepatitis B e antigen

Clinica Chimica Acta, 2015
Hepatitis 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 virus infection: implications in transfusion

Vox Sanguinis, 2004
Hepatitis 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].

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.
