Occult hepatitis B virus infection

World Journal of Hepatology, 2014
Occult hepatitis B virus (HBV) infection (OBI) refers to the presence of HBV DNA in the absence of detectable hepatitis B surface antigen. Since OBI was first described in the late 1970s, there has been increasing interest in this topic. The prevalence of OBI varies according to the different endemicity of HBV infection, cohort characteristics, and ...

Interferon-α for Immune Modulation in Chronic Hepatitis B Toward Functional Cure

Viruses
Chronic hepatitis B (CHB) remains a major global health challenge, largely due to the persistence of covalently closed circular DNA (cccDNA) and impaired host immunity.

Drug-related mutational patterns in hepatitis B virus (HBV) reverse transcriptase proteins from Iranian treatment-Naïve chronic HBV patients [PDF]

, 2013
Background: Immunomodulators and Nucleotide analogues have been used globally for the dealing of chronic hepatitis B virus (HBV) infection. However, the development of drug resistance is a major limitation to their long-term effectiveness.

A novel monoclonal antibody targeting a conserved inner region of the hepatitis B virus envelope enables broad detection of immune escape variants

Virus Research
The detection of hepatitis B surface antigen (HBsAg) is fundamental for the diagnosis of chronic hepatitis B (CHB). However, current diagnostic assays that rely on antibodies targeting the conformational “a” determinant of HBsAg are frequently ...

Kinetics of acute hepatitis B virus infection in humans [PDF]

, 2001
Using patient data from a unique single source outbreak of hepatitis B virus (HBV) infection, we have characterized the kinetics of acute HBV infection by monitoring viral turnover in the serum during the late incubation and clinical phases of the ...

Hepatitis B virus and hepatitis C virus dual infection

World Journal of Gastroenterology, 2014
Hepatitis B virus (HBV) and hepatitis C virus (HCV) share common mode of transmission and both are able to induce a chronic infection. Dual HBV/HCV chronic coinfection is a fairly frequent occurrence, especially in high endemic areas and among individuals at high risk of parenterally transmitted infections.
