This study aimed to develop a more sensitive method for the detection of hepatitis B surface antigen (HBsAg) using heteroassembled gold nanoparticles (AuNPs). A single layered localized surface plasmon resonance (LSPR) chip format was developed with antigen-antibody reaction-based detection symmetry using AuNPs, which detected HBsAg at 10 pg/mL. To further improve the detection limit, a modified detection format was fabricated by fixing a secondary antibody (to form a heteroassembled sandwich format) to the AuNP monolayer, which enhanced the detection sensitivity by about 100 times...

Long-term in vitro liver models are now widely explored for human hepatic metabolic clearance prediction, enzyme phenotyping, cross species metabolism, comparison of low clearance drugs as well as induction studies. Here, we present studies using a long-term liver model which show how metabolism and active transport, drug-drug interactions and enzyme induction in healthy and diseased states, e.g. hepatitis B virus (HBV) infection, may be assessed in a single test system to enable effective data integration for PBPK modeling...

A hallmark of hepatitis B virus (HBV) infection is the presence of hepatitis B surface antigen (HBsAg) in the serum of patients. Sustained loss of HBV DNA and HBsAg from the blood are main goals for treatment, and considered as functional cure. It is rarely achieved with long-term nucleoside analogue treatment though, both because cccDNA, the template for viral replication, is not completely cleared, and probably also because hepatocytes with HBV DNA integrated into their chromosomes persist and continue to produce large amounts of HBsAg...

Christoph Seeger
Chronic hepatitis B virus infections affect over 250 million people world-wide, and, at present, are not curable. Of those, over 800000 are expected to die yearly from complications including cirrhosis and primary hepatocellular carcinoma (HCC). A viral episomal DNA intermediate, covalently closed circular DNA (cccDNA) can persist in nuclei of infected hepatocytes and trigger production of infectious virus. Current standard of care treatments against chronic HBV infections primarily rely on nucleoside analogs (NA) that inhibit de novo virus production by inhibiting the viral reverse transcriptase and, as a consequence, reducing virus titers...

BACKGROUND & AIM: Chronic infection with hepatitis B virus (HBV) in children possesses a serious health problem worldwide. It remains unresolved how children with immune-tolerant chronic hepatitis B should be treated, who were commonly characterized by HBeAg positivity, high viral load, normal or mildly elevated ALT and no or minimal inflammation in liver histology. This trial aims to study the benefits of antiviral therapy in children with these characters. METHODS: This is a pilot open-lable randomized controlled study...

BACKGROUND: Neuroendocrine tumors (NETs) metastasize to the liver. Everolimus and selective internal radioembolization (SIRT) are approved treatments. Pasireotide is a somatostatin analogue with an affinity for somatostatin receptors 1, 2, 3, and 5. Everolimus and pasireotide may potentiate SIRT radiosensitization and inhibit rebound angiogenesis. This study evaluated the safety of pasireotide, everolimus, and SIRT. METHODS: This 3 + 3 phase 1 trial evaluated 3 dose levels of everolimus (2...

Background/Aims: The optimal duration of nucleos(t)ide analogs (NAs) therapy in chronic hepatitis B (CHB) patients remains unsatisfactory. Previous studies have confirmed the important role of host genetic factors in determining the outcome of HBV infection. This study tries to determine the role of host genetic factors in predicting response status in CHB patients discontinuing NAs according to stringent cessation criteria. Patients and Methods: Participating patients came from a prospective NAs- discontinuation cohort since June 1999...

Each year, nearly 900,000 deaths are due to serious liver diseases caused by chronic hepatitis B virus infection. The viral particle is composed of an outer envelope and an inner icosahedral nucleocapsid formed by multiple dimers of a ~ 20 kDa self-assembling core protein (Cp). Here we report the solid-state 13 C and 15 N resonance assignments of the assembly domain, Cp149, of the core protein in its capsid form. A secondary chemical shift analysis of the 140 visible residues suggests an overall alpha-helical three-dimensional fold matching that derived for Cp149 from the X-ray crystallography of the capsid, and from solution-state NMR of the Cp149 dimer...
