AI Article Synopsis

  • Current treatments for hepatitis B virus (HBV) infection usually don't completely eliminate the virus, leading to a potential return of the virus after stopping treatment.
  • Research is focused on finding new ways to target both the virus and the host to improve therapies and prevent complications from HBV.
  • Recent studies highlight various promising approaches, including targeting specific viral components and enhancing immune responses, indicating that achieving a functional cure for HBV may soon be possible.

Article Abstract

: Current therapy for infection with hepatitis B virus (HBV) rarely clears the virus, and viremia commonly resurges following treatment withdrawal. To prevent serious complications of the infection, research has been aimed at identifying new viral and host targets that can be exploited to inactivate HBV replication.: This paper reviews the use of these new molecular targets to advance anti-HBV therapy. Emphasis is on appraising data from pre-clinical and early clinical studies described in journal articles published during the past 10 years and available from PubMed.: The wide range of viral and host factors that can be targeted to disable HBV is impressive and improved insight into HBV molecular biology continues to provide the basis for new drug design. In addition to candidate therapies that have direct or indirect actions on HBV covalently closed circular DNA (cccDNA), compounds that inhibit HBsAg secretion, viral entry, destabilize viral RNA and effect enhanced immune responses to HBV show promise. Preclinical and clinical evaluation of drug candidates, as well as investigating use of treatment combinations, are encouraging. The field is poised at an interesting stage and indications are that reliably achieving functional cure from HBV infection is a tangible goal.

Prediction of cccDNA dynamics in hepatitis B patients by a combination of serum surrogate markers.

PLoS Comput Biol

Quantification of intrahepatic covalently closed circular DNA (cccDNA) is a key for evaluating an elimination of hepatitis B virus (HBV) in infected patients. However, quantifying cccDNA requires invasive methods such as a liver biopsy, which makes it impractical to access the dynamics of cccDNA in patients. Although HBV RNA and HBV core-related antigens (HBcrAg) have been proposed as surrogate markers for evaluating cccDNA activity, they do not necessarily estimate the amount of cccDNA.

HBV genotype A has two major subtypes, A1 (commonly in Africa) and A2 (commonly in Europe) with only 4% nucleotide differences. Individuals infected with these two subtypes appear to have different clinical manifestations and virologic features. Whether such a difference results from the virus or host has not been established.

The murine hepatitis virus (MHV) is an important model system for studying coronavirus (CoV) molecular and cell biology. Despite this, few reagents for MHV are available through repositories such as ATCC or Addgene, potentially limiting the widespread adoption of MHV as a tractable model system. To overcome some challenges inherent in the existing MHV reverse genetics systems, we developed a plasmid-launched transformation-associated recombination (TAR) cloning-based system to assemble the MHV (strain A59; MHV-A59) genome.

Resistance-associated substitutions (RASs) are mutations within the hepatitis C (HCV) genome that may influence the likelihood of achieving a sustained virological response (SVR) with direct acting antiviral (DAA) treatment. Clinicians conduct RAS testing to adapt treatment regimens with the intent of improving the likelihood of cure. The Canadian Network Undertaking against Hepatitis C (CANUHC) prospective cohort consists of chronic HCV patients enrolled between 2015 and 2023 across 17 Canadian sites.

Aims: Exploring fibrosis index-4 (FIB-4)'s predictive value for HBV-related hepatocellular carcinoma (HCC) in assessing recurrence following stereotactic body radiation therapy (SBRT) in patients with HBV-related HCC.

Methods: HBV-related HCC patients who underwent SBRT were retrospectively enrolled from March 2012 to March 2020. Patients were divided into recurrence and non-recurrence groups based on the HCC recurrence situation.
