Immunocompromised patients with HBsAg a determinant mutants: comparison of HBsAg diagnostic assays.

Intervirology, 2010
Hepatitis B surface antigen (HBsAg) is considered the best marker for the diagnosis of hepatitis B virus (HBV) infection. Mutations of the s gene involving amino acid substitutions within the a determinant could affect the sensitivity of diagnostic tests.

Mitochondrial stress in advanced fibrosis and cirrhosis associated with chronic hepatitis B, chronic hepatitis C, or nonalcoholic steatohepatitis

Hepatology, EarlyView., 2022
Adaptive mitochondrial mechanisms allow mitochondrial resilience and prevent the worsening of fibrosis, while deregulation of these mechanisms promotes the progression from no/minimal‐mild (F0‐F2) fibrosis to advanced fibrosis and cirrhosis (F3‐F4). Abstract Background and Aims Hepatitis B virus (HBV) infection causes oxidative stress (OS) and alters ...

MORPHOLOGICAL ANALYSIS OF HEPATITIS B VIRUS WITH ESCAPE MUTATIONS IN S-gene G145R AND S143L

Вопросы вирусологии, 2017
Background. In terms of serological properties and immunization, the wild type of HBsAg HBV and its G145R mutant behave as different antigens. This testifies to serious structural changes, which presumably could have a significant impact on the ...

Dried Blood Spot: A Tool to Ensure Broad Access to Hepatitis D Screening, Diagnosis, and Treatment Monitoring. [PDF]

Liver Int
ABSTRACT Background and Aims Chronic hepatitis D is the most severe form of viral hepatitis. Despite recommendations for systematic screening of HBsAg‐positive individuals, hepatitis D infection remains underdiagnosed. Standard HDV virological markers are classically assessed in serum or plasma specimens obtained through venous whole blood sampling ...

Low Hepatitis B Core-Related Antigen Levels Correlate Higher Spontaneous Seroclearance of HBsAg in Chronic Hepatitis B Patients with High HBsAg Levels

, 2023
Background & aims: Seroclearance of hepatitis B surface antigen (HBsAg) indicates functional cure for hepatitis B virus (HBV) infection. Low HBsAg levels can predict HBsAg seroclearance over time.
