Clinical impact of occult HBV infections
Journal of Clinical Virology, 2005HBV infection in the absence of HBsAg has been a matter of debate for years, but its existence and clinical relevance are now supported by many publications, editorials and reviews. HBV DNA without HBs antigenemia was detected in the following clinical situations: (1) Chronic, presumably viral, hepatitis unrelated to HCV, atypical alcoholic hepatitis ...

Occult HBV Infection in Multi Transfused Thalassemia Patients
The Indian Journal of Pediatrics, 2014To determine the prevalence of Hepatitis B virus (HBV) and Hepatitis C virus (HCV) infection in multitransfused thalassemic patients, with an aim to further highlight the need for donor screening strategy with supplementary molecular diagnostic tools for high risk population.The study was conducted in 174 thalassemic subjects from Thalassemia unit of ...

Moving towards core antigen for the management of patients with overt and occult HBV infection.
Panminerva Medica (Testo stampato), 2020Chronic hepatitis B virus (HBV) infection encompasses a wide virologic and clinical spectrum with heterogeneous outcomes. The natural history of chronic HBV infection ranges from an inactive carrier state (hepatitis B e antigen-negative chronic infection)

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 HCV and occult HBV coinfection in Iranian human immunodeficiency virus‐infected individuals
Journal of Medical Virology, 2020AbstractThe presence of hepatitis C virus (HCV) genome in liver biopsy or peripheral blood mononuclear cell (PBMC) specimens in the absence of detectable HCV‐RNA in plasma of the people with or without anti‐HCV antibodies has defined as occult HCV infection (OCI), whereas occult hepatitis B virus infection (OBI) is detection of hepatitis B virus (HBV ...

Occult HBV infection in untreated HIV-infected adults in Côte d'Ivoire
Antiviral Therapy, 2010Background 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 ...

Background There is controversial data on possible occult HBV reactivation in HCV patients successfully treated with direct-acting antivirals (DAA). However, diagnosis of occult HBV infection (OBI) was not performed by gold standard procedures in any ...

Molecular Diagnosis of Occult HCV and HBV Infections
Future Virology, 2007Occult 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 ...

Occult HBV infection in cryptogenic liver cirrhosis in an area with high prevalence of HBV infection
The American Journal of Gastroenterology, 2002Hepatitis B surface antigen (HBsAg) is often used as the serological marker to screen for hepatitis B virus (HBV) infection in the investigation of liver cirrhosis. In Hong Kong, where HBV infection is endemic, some patients may have persistent viral infection after the loss of HBsAg. We aimed to investigate 1) the prevalence of occult HBV infection in
