This study characterized a hepatitis B virus (HBV) hybridization-capture next-generation sequencing (HBV-NGS) assay and applied it to develop a model for estimating the integrated HBV DNA (iDNA) quantity and for HBV genetics liquid biopsy. Using HBV monomers and reconstituted cell line DNA (SNU398, Hep3B, and PLC/PRF/5), the HBV-NGS assay demonstrated high coverage uniformity, reproducibility across HBV genotypes A-D, and 0.1% sensitivity for detecting iDNA. The iDNA sequence and structures from SNU398 and Hep3B are reported. An iDNA estimation model was developed using tissue biopsies from patients with serum viral load < 4 log IU/mL and validated using SNU398 and Hep3B cell line DNA. The assay's utility for HBV genetic liquid biopsy was evaluated using matched plasma-urine samples with HBV DNA levels ranging from high to undetectable. In this pilot study, HBV-JS was detected in all body fluids, regardless of viral load. These findings indicate that the iDNA from patients with negligible or undetectable viral replication can be assessed for iDNA elimination efficacy in drug development. Moreover, a sensitive HBV genetics liquid biopsy can be feasible even for patients with undetectable serum viral load. This study underscores the potential of NGS-based methods to advance HBV management.

BackgroundHepatitis B virus (HBV) disproportionately affects people at risk of HIV. Encounters for HIV post-exposure prophylaxis (PEP) create opportunities for HBV screening and prevention. We quantified HBV prevalence, susceptibility, and active/passive immunization use among patients seeking HIV PEP.

Rapid and accurate detection of DNA from disease-causing pathogens is essential for controlling the spread of infections and administering timely treatments. While traditional molecular diagnostics techniques like PCR are highly sensitive, they include nucleic acid amplification and many need to be performed in centralized laboratories, limiting their utility in point-of-care settings. Recent advances in CRISPR-based diagnostics (CRISPR-Dx) have demonstrated the potential for highly specific molecular detection, but the sensitivity is often constrained by the slow trans-cleavage activity of Cas enzymes, necessitating preamplification of target nucleic acids.

This paper highlights the innovative approach and findings of the recently published study by Xu , which underscores the integration of radiomics and clinicoradiological factors to enhance the preoperative prediction of microvascular invasion in patients with hepatitis B virus-related hepatocellular carcinoma (HBV-HCC). The study's use of contrast-enhanced computed tomography radiomics to construct predictive models offers a significant advancement in the surgical planning and management of HBV-HCC, potentially transforming patient outcomes through more personalized treatment strategies. This editorial commends the study's contribution to precision medicine and discusses its implications for future research and clinical practice.

These infections drive persistent liver inflammation, culminating in cellular dysregulation, fibrosis, and cancer. Despite advancements in targeted therapies, drug resistance and the lack of reliable biomarkers for patient stratification still terribly hinder the treatment of viral HCC.
