Higher FIB-4 index at baseline predicts development of liver cancer in a community-based cohort with viral hepatitis.

Hepatitis B and C (HBV and HCV) testing has been performed in Japan since 2002 and is subsidized by central and prefectural governments. A follow-up program for HBV- or HCV-infected persons was started at that time in Ishikawa Prefecture. This study analyzed the long-term follow-up data from this program.

Comprehensive genomic profiling for advanced hepatocellular carcinoma in clinical practice.

Aim: Although several therapeutic agents show efficacy in advanced hepatocellular carcinoma (HCC), biomarkers such as comprehensive genomic profiling (CGP) for the selection of second-line treatments after immunotherapy have not been established. We evaluated the value of CGP for the treatment decision in patients with HCC.

Methods: We retrospectively studied 52 patients with advanced HCC who received CGP tests at three tertiary hospitals between February 2022 and November 2023.

High-Throughput Screening of Antiviral Compounds Using a Recombinant Hepatitis B Virus and Identification of a Possible Infection Inhibitor, Skimmianine.

We developed a novel hepatitis B virus (HBV) infection-monitoring system using a luminescent, 11-amino acid reporter (HiBiT). We performed high-throughput antiviral screening using this system to identify anti-HBV compounds. After the infection of primary human hepatocytes with the recombinant virus HiBiT-HBV, which contains HiBiT at its preS1, 1262 compounds were tested in a first screening using extracellular HiBiT activity as an indicator of viral infection.

Programmed cell death-1 is involved with peripheral blood immune cell profiles in patients with hepatitis C virus antiviral therapy.

Mutations in the non-structural protein regions of hepatitis C virus (HCV) are a cause of a non-sustained virological response (SVR) to treatment with direct-acting antivirals (DAAs) for chronic hepatitis; however, there are non-SVR cases without these mutations. In this study, we examined immune cell profiles in peripheral blood before and after ombitasvir/paritaprevir/ritonavir treatment and screened for genes that could be used to predict the therapeutic effects of DAAs. Fluorescence-activated cell sorting analysis indicated that the median frequencies of programmed cell death-1-positive (PD-1+) effector regulatory T cells (eTregs), PD-1+CD8+ T cells, and PD-1+Helper T cells were decreased significantly in SVR cases, but without significant changes in non-SVR cases.

Endoscopic treatment of bile duct stones with benign choledochojejunal anastomotic stenosis.

Background And Aims: Endoscopic interventions for bile duct stones (BDSs) with benign choledochojejunal anastomotic stenosis (bCJS) are challenging. Therefore, we investigated endoscopic interventions for BDSs with bCJS.

Methods: Seventeen patients with BDSs with bCJS were retrospectively analyzed.
