Occult Hepatitis B and Other Unexplored Risk Factors for Hepatocellular Carcinoma in Latin America

Annals of Hepatology, 2018
Occult hepatitis B infection (OBI) is the presence of hepatitis B virus (HBV) DNA in the liver and/or serum (< 200 IU/mL) in HBsAg-negative patients with or without serologic markers of previous viral exposure.

Hepatitis B Core IgM antibody (anti-HBcIgM) among hepatitis B Surface antigen (HBsAg) negative blood donors in Nigeria

Virology Journal, 2011
Background Transfusion associated Hepatitis B virus (TAHBV) continues to be a major problem despite mandatory screening for Hepatitis B surface Antigen (HBsAg). Presence of HBsAg is the common method for detecting hepatitis B infection.

Permanent loss of anti-HBc after reactivation of hepatitis B virus infection in an anti-HBs and anti-HBc-positive patient after allogeneic stem cell transplantation

, 2007
Background: Reactivation of a hepatitis B virus (HBV) infection after transplantation is associated with a high morbidity and mortality. HBV infections generally result in anti-HBc persisting lifelong. Case report: A 44-year-old female presented 10 years

Prevalence of Occult and Mutant HBV Infection in Hospitalized Haematological Patients [PDF]

Клиническая микробиология и антимикробная химиотерапия, 2016
A total of 717 serum samples from haematological patients, who were hospitalized in Botkin City Clinical Hospital (Moscow) in the 2011–2014, were tested. High frequency of hepatitis B virus (HBV) serologic markers was established: HBsAg — 4.5%; anti-HBc +

Occult hepatitis B virus infection in immunocompromised patients

Brazilian Journal of Infectious Diseases
Occult hepatitis B infection is characterized by hepatitis B virus (HBV) DNA in the serum in the absence of hepatitis B surface antigen (HBsAg). We assessed occult HBV infection prevalence in two groups of immunocompromised patients (maintenance ...

Estimation of HBV-DNA Existence By Quantitative Anti-HBC Detection

, 2006
Although it is a weak possibility, post-transfusional hepatitis B infection is reported due to HBsAg screening only before transfusion. Adding anti-HBc antibody to the screening and excluding anti-HBc positive cases may obscure finding donors enough. The
