Spontaneous reactivation of hepatitis B virus (HBV) infection in patients with resolved or occult HBV infection

Journal of Medical Virology, 2015
Reactivation of a former hepatitis B virus (HBV) infection can be triggered by immunosuppressive therapy, diseases associated with an immunocompromised state, organ transplantation or the withdrawal of antiviral drugs. Despite the absence of such risk factors, a spontaneous reactivation of HBV replication occurred in two elderly patients with resolved ...

Occult HBV infection in untreated HIV-infected adults in Côte d'Ivoire

Antiviral Therapy, 2010
Background In countries with high rates of chronic HBV, the World Health Organization recommends screening all HIV-infected adults for hepatitis B surface antigen (HBsAg) before initiating antiretroviral therapy (ART), and starting HIV–HBV-coinfected patients on regimens containing lamivudine (3TC) or emtricitabine (FTC) plus tenofovir disoproxil ...

Molecular Diagnosis of Occult HCV and HBV Infections

Future Virology, 2007
Occult HCV and HBV infections are recently identified entities whose existence became evident when nucleic acid amplification assays of enhanced sensitivity were employed for the detection of viral genomes and their replicative intermediates. These long-term silent infections are consequences of persistent low-level viral replication progressing in ...

To see the HBV DNA detection instance in the HBsAg negative people and to study the serological method detection strategy for detecting hepatitis B virus large surface protein (HBLP) to filtrate the occult HBV infection.The HBsAg negative serum samples were divided into HBsAb negative and positive two species according to the hepatitis B virus markers (

Occult HBV Infection in Nigeria.

Archives of basic and applied medicine
Occult hepatitis B virus infection (OBI) is manifested by presence of HBV-DNA in the absence of detectable Hepatitis B surface antigen (HBsAg) with or without anti-HBV antibodies. Hence it is a potential threat in blood transfusion medicine. This study was carried out to determine the prevalence of OBI as well as evaluate the effectiveness of using ...

Molecular mechanisms underlying HBsAg negativity in occult HBV infection

European Journal of Clinical Microbiology & Infectious Diseases, 2015
Although genomic detection is considered the gold standard test on HBV infection identification, the HBsAg investigation is still the most frequent clinical laboratory request to diagnose HBV infection in activity. However, the non-detection of HBsAg in the bloodstream of chronic or acutely infected individuals has been a phenomenon often observed in ...

Occult HBV infection in PBMCs of HIV+ individuals

2010
Backgrund and aim: Detection of HBV-DNA in HBsAg negative patients is defined as occult HBV infection. Previously, we investigated the prevalence and the genomic heterogeneity of occult HBV in the liver of 24 HIV+/HbsAg negative patients: 8 HBsAg- patients were HBV-DNA positive (33%) in the liver. HBV can be detected in PBMCs, so infected PBMCs can act
