Predominance of HBV Genotype B and HDV Genotype 1 in Vietnamese Patients with Chronic Hepatitis

Viruses, 2021
Hepatitis delta virus (HDV) coinfection will additionally aggravate the hepatitis B virus (HBV) burden in the coming decades, with an increase in HBV-related liver diseases.

Detecting Hepatitis B Surface Antigen Mutants

Emerging Infectious Diseases, 2006
Hepatitis B viral mutants can emerge in patients as a result of selection pressure from either immune response or treatment options. Mutations that occur within the immunodominant epitopes of hepatitis B surface antigen (HBsAg) allow mutant virus to propagate in the presence of a neutralizing immune response, while wild-type virus is reduced to ...

Clinical features of chronic hepatitis B patients with low hepatitis B surface antigen levels and determinants of hepatitis B surface antigen seroclearance [PDF]

JGH Open, 2020
AbstractBackground and AimA low hepatitis B surface antigen (HBsAg) level is reported to be predictive of future HBsAg seroclearance. A hospital‐based cohort study was conducted to clarify the clinical features of patients with low HBsAg levels and to demonstrate the usefulness of low HBsAg levels for predicting HBsAg seroclearance.MethodsA total of ...

Predictive value of HBeAg titer dynamics for HBsAg clearance in pediatric chronic hepatitis B

Frontiers in Pediatrics
IntroductionAchieving functional cure of chronic hepatitis B (CHB), characterized by the loss of HBV DNA and HBsAg, remains challenging in adults but demonstrates higher success rates in children.

Immune response to hepatitis B surface antigen [PDF]

Infection and Immunity, 1975
A total of 69 persons were investigated for assessment of cell-mediated and humoral immunity to hepatitis B surface antigen (HBsAg). Three groups, each consisting of 20 normal persons, 20HBsAg carriers, and 20 convalescent hepatitis B patients, were studied for HBsAg, anti-HBs, and leukocyte migration inhibition with purified HBsAg. Sequential sampling

Intracellular Dynamics of Hepatitis B Virus Infection: A Mathematical Model and Global Sensitivity Analysis of Its Parameters [PDF]

arXiv, 2023
Analysis of cell population can reveal the average information about the viral infection in host whereas single-cell analysis can capture the individual consideration. Single-cell analysis can also provide new ways to explore viral diversities and identify the intrinsic extreme phenotype of the cells. In this study, a single-cell hepatitis B virus (HBV)

Mathematical model of immune response to hepatitis B [PDF]

J. Theor. Biol. 447, 98-110 (2018), 2018
A new detailed mathematical model for dynamics of immune response to hepatitis B is proposed, which takes into account contributions from innate and adaptive immune responses, as well as cytokines. Stability analysis of different steady states is performed to identify parameter regions where the model exhibits clearance of infection, maintenance of a ...

Method for identification of condition-associated public antigen receptor sequences [PDF]

eLife 2018;7:e33050, 2017
Diverse repertoires of hypervariable immunoglobulin receptors (TCR and BCR) recognize antigens in the adaptive immune system. The development of immunoglobulin receptor repertoire sequencing methods makes it possible to perform repertoire-wide disease association studies of antigen receptor sequences.
