Escaping high viral load exhaustion: CD8 cells with altered tetramer binding in chronic hepatitis B virus infection [PDF]

open access: yes, 2002
Deletion, anergy, and a spectrum of functional impairments can affect virus-specific CD8 cells in chronic viral infections. Here we characterize a low frequency population of CD8 cells present in chronic hepatitis B virus (HBV) infection which survive in

Epidemiological patterns of hepatitis B virus (HBV) in highly endemic areas [PDF]

open access: yes, 1996
This paper uses meta-analysis of published data and a deterministic mathematical model of hepatitis B virus (HBV) transmission to describe the patterns of HBV infection in high endemicity areas.

Viral adaptation to host immune responses occurs in chronic hepatitis B virus (HBV) infection, and adaptation is greatest in HBV e antigen-negative disease [PDF]

open access: yes, 2012
Hepatitis B virus (HBV)-specific T-cell responses are important in the natural history of HBV infection. The number of known HBV-specific T-cell epitopes is limited, and it is not clear whether viral evolution occurs in chronic HBV infection. We aimed to

Molecular and serological characterization of hepatitis B vaccine breakthrough infections in serial samples from two plasma donors

open access: yesVirology Journal, 2019
Background Although vaccines for hepatitis B virus (HBV) are highly effective, HBV infections in vaccinees occur. Index samples of breakthrough infections are typically anti-HBc negative but HBV DNA positive with protective anti-HBs levels while HBsAg ...

Changes in viral load and HBsAg and HBeAg status with age in HBV chronic carriers in The Gambia. [PDF]

open access: yes, 2008
BACKGROUND: Little is known about changes in hepatitis B viral load (HBV DNA) in relation to age in Africa. The aim of this study is to determine the natural course of HBV chronic infection, particularly in relation to sequential changes in serum HBV DNA

Hepatitis B virus reactivation sustained by a hepatitis B virus surface antigen immune-escape mutant isolate in a patient who was hepatitis B core antibody positive during treatment with sofosbuvir and velpatasvir for hepatitis C virus infection: a case report

open access: yesJournal of Medical Case Reports, 2019
Background Although several cases of hepatitis B virus reactivation have been described in patients with a history of hepatitis B virus infection while undergoing treatment for hepatitis C virus infection with direct acting antivirals, the question of ...

Dynamic Characteristics of Serum Hepatitis B Surface Antigen in Chinese Chronic Hepatitis B Patients Receiving 7 Years of Entecavir Therapy

open access: yesChinese Medical Journal, 2016
Background: The ultimate goal of hepatitis B treatment is hepatitis B surface antigen (HBsAg) seroclearance. Several factors have been suggested to be associated with the rate of HBsAg reduction in antiviral-naive or lamivudine therapy cohorts.

Can HBsAg Be Used as a Viral Replication Marker in Chronic Hepatitis B Patients?

open access: yesViral Hepatitis Journal, 2017
Objective: Monitoring hepatitis B virus (HBV) treatment responses and virus replication is performed with molecular tests. However, these tests are either expensive or invasive. A new and more practical marker is needed.
