AI Article Synopsis

  • The study aimed to create a highly sensitive and reproducible real-time PCR (RTD-PCR) assay for measuring HBV DNA levels in patients with hepatitis B virus infection.
  • By analyzing serial dilutions, it was found that the assay could detect as low as 1 DNA copy per reaction and spanned a 10-log10 range.
  • The RTD-PCR method showed greater sensitivity compared to commercial tests and demonstrated strong consistency in results, indicating its potential as an effective tool for monitoring HBV treatment.

Article Abstract

HBV DNA quantitation is used extensively for the monitoring of treatment of hepatitis B virus (HBV) infection. The aim of this study was to develop a highly sensitive and reproducible real-time PCR (RTD-PCR) assay for the quantitation of HBV DNA using the LightCycler system. The performance of this assay was assessed by analyzing serial dilutions of HBV genomic DNA of known concentration and the lower limit of detection was found to be 1 DNA copy/reaction. By using serial dilutions of plasmid standard, RTD-PCR was determined to quantify HBV DNA in a 10-log10 dynamic range. RTD-PCR was found to be more sensitive than the commercially available tests such as the Quantiplex HBV DNA and the AMPLICOR HBV MONITOR assays. The median coefficient of variation of interexperimental variability was 3.2%. The HBV DNA values obtained with RTD-PCR were highly correlated with assays available commercially. These findings suggest that our RTD-PCR assay combines high sensitivity and reproducibility for HBV DNA quantitation in an incomparable high dynamic range of quantitation.

Chronic hepatitis B virus (HBV) infection can significantly increase the incidence of cirrhosis and liver cancer, and there is no curative treatment. The persistence of HBV covalently closed circular DNA (cccDNA) is the major obstacle of antiviral treatments. cccDNA is formed through repairing viral partially double-stranded relaxed circular DNA (rcDNA) by varies host factors.

Introduction: Hepatitis B reactivation and administration of prophylactic antiviral treatment are considered in patients with autoimmune inflammatory rheumatic diseases (AIIRD) undergoing immunosuppressive/immunomodulatory treatment. Data are more robust for rheumatoid arthritis patients receiving bDMARDs but are limited for other AIIRD and drug categories.

Methods: Adult patients with AIIRD (inflammatory arthritis [IA] or connective tissue diseases [CTD]) and documented chronic or resolved HBV infection (defined as serum HBsAg positivity or anti-HBcAb positivity in the case of HBsAg non-detection respectively), followed-up in six rheumatology centers in Greece and Italy, were included.

Hepatitis B virus (HBV) DNA integration into the host cell genome is reportedly a major cause of liver cancer, and a source of hepatitis B surface antigen (HBsAg). High HBsAg levels can alter immune responses which therefore contributes to the progression of HBV-related disease. However, to what extent integration leads to the persistent circulating HBsAg is unclear.

The role of pre-treatment HBV DNA levels on the prognosis of hepatitis B virus-related decompensated cirrhosis is unclear. This study investigated the effects of pre-treatment HBV DNA and other determinants on short-term and long-term survival of chronic hepatitis B (CHB) patients with decompensated cirrhosis. A total of 278 cirrhotic decompensated CHB patients treated with entecavir or tenofovir disoproxil fumarate were retrospectively enrolled.

The rapid, precise, and automated diagnosis of infectious diseases is crucial for effective disease management and control. Herein, the integrated portable and automatic digital detection system (IPADS), a novel diagnostic platform for nucleic acid detection is introduced. The device employs the hybrid magnetic system (HMS), which uses an electromagnet and a movable permanent magnet to modulate the magnetic field and control bead movement, increasing nucleic acid extraction efficiency to over 80%, while simplifying the traditional labor-intensive process and enabling quick, low-risk sample processing.
