Introduction And Objectives: Identifying hepatitis B virus (HBV) patients eligible for safe nucleos(t)ide analogues (NAs) discontinuation remains challenging. Discrepant data on combined HBV DNA and quantitative HBV surface antigen (qHBsAg) assessments are available. This study aimed to identify potential predictors for safe treatment discontinuation by evaluating clinical/virological outcomes in patients on long-term NA therapy.
Patients And Methods: A retrospective cohort of 139 chronic hepatitis B (CHB) patients - who consecutively started Entecavir or Tenofovir from 2007 to 2011 - was evaluated. The study population was selected based on anti-HBe positivity, absence of prior antiviral treatment, absence of non-HBV-related liver diseases or hepatocellular carcinoma (HCC), and long-term clinical/ultrasonographic/laboratory evaluations post-NA initiation. Serum samples collected before starting NA (T0) and over ten years (T1-T10) were tested for HBV DNA and qHBsAg.
Results: Twenty-two/139 (15.8 %) CHB patients (12 chronic hepatitis, 10 cirrhosis) met the inclusion criteria. All patients showed a significant decrease in liver stiffness values in the ten years of follow-up (p = 0.001), and no hepatic decompensation occurred. Three/22 (13.6 %) patients developed HCC. Ten/22 patients (45.5 %; group-A) had fluctuating HBV DNA, while other 10/22 (45.5 %; group-B) showed undetectable HBV DNA for 5-9 years with more significant qHBsAg decline (p = 0.04) than group-A. Two/22 (9.1 %) patients showed a critical qHBsAg decline up to seroconversion together with undetectable HBV DNA.
Conclusions: Persistent undetectable HBV DNA levels correlate with qHBsAg reduction and the potential HBsAg seroclearance, suggesting that long-term HBV DNA monitoring in NA-treated CHB patients might help identify candidates for treatment discontinuation.

In a population-based survey, Hepatitis B virus (HBV) infection status, associated risk factors and vaccine coverage among the 4006 Particularly Vulnerable Tribal Groups (PVTG) participants of Odisha Tribal Family Health Survey (OTFHS) were assessed using various viral markers. All the HBsAg-positive sera were screened for viral load estimation, envelopment antigen (HBeAg) identification and liver profile parameters. The overall prevalence of HBsAg was 5.

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.

The number of observed cases of occult hepatitis B virus infection (OBI) in eastern India has been increasing. Here, S gene mutations were identified in apparently healthy individuals with OBI, and the S protein variants from these patients were characterized in vitro. Plasma samples from 217 healthy blood donors were collected from three different regions in eastern India and screened for hepatitis B virus (HBV) infection using a nucleic acid amplification test and immunoassays for serological markers.

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.

Background: The HBx protein of hepatitis B virus (HBV) plays a crucial role in HBV pathogenesis, yet current treatments like HIV reverse transcriptase (RT) inhibitors, which target HBV RT due to similar active sites, have severe side effects, risk of drug resistance, and high costs. The present study investigates the anti-hepatitis B virus (HBV) properties of Andrographis paniculata (AP) and Thespesia populnea (TP) on HBV expressing HepG2.2.
