Hepatitis B virus (HBV) infection is a global problem and a major risk factor for hepatocellular carcinoma (HCC). microRNAs (miRNAs) comprise a group of small noncoding RNAs regulating gene expression at the posttranslational level, thereby participating in fundamental biological processes, including cell proliferation, differentiation, and apoptosis. In this review, we summarize the roles of miRNAs in HBV infection, the recently identified mechanism underlying dysregulation of miRNAs in HBV-associated HCC, and their association with hepatocarcinogenesis. Moreover, we discuss the recent advances in the use of circulating miRNAs in the early diagnosis of HCC as well as therapies based on these aberrantly expressed miRNAs.

Background: A multivariate predictive model was constructed using baseline and 12-week clinical data to evaluate the rate of clearance of hepatitis B surface antigen (HBsAg) at the 48-week mark in patients diagnosed with chronic hepatitis B who are receiving treatment with pegylated interferon α (PEG-INFα).
Methods: The study cohort comprised CHB patients who received pegylated interferon treatment at Mengchao Hepatobiliary Hospital, Fujian Medical University, between January 2019 and April 2024. Predictor variables were identified (LASSO), followed by multivariate analysis and logistic regression analysis.

Background: Oxidative stress plays a crucial role in the pathogenesis of HBV. This study aimed to investigate the value of fibroblast growth factor 21 (FGF21) promoter methylation in the occurrence and development of chronic hepatitis B (CHB) oxidative stress.
Methods: A total of 241 participants including 221 patients with CHB and 20 healthy controls (HCs) were recruited.

Zanzibar, a low-resource semiautonomous region of Tanzania, has an estimated prevalence of hepatitis B virus (HBV) infections of 3.6%. To assess the feasibility of care and treatment, a 5-year hepatitis B demonstration project was implemented in Zanzibar during January 2017-December 2021, following the 2015 WHO HBV care and treatment guidelines.

Background: People who inject drugs (PWID) are at high risk of blood-borne infections, and injection drug use contributes significantly to hepatitis C virus (HCV) transmission. The WHO has therefore set targets of reducing HCV incidence and prevalence among PWID and increasing treatment coverage to eliminate HCV by 2030. The DRUCK study (2011-2014) found high HCV prevalence and low treatment coverage among PWID in Germany.

In preclinical studies, GST-HG141, a novel hepatitis B virus (HBV) capsid assembly modulator displayed potent anti-HBV activity in vitro and strong efficacy in HBV animal models. A randomized, double-blind, ascending phase 1b trial assessed the pharmacokinetics, safety, and efficacy of GST-HG141 in chronic hepatitis B (CHB) individuals. Thirty treatment-naïve CHB patients were enrolled in three cohorts (25, 50, and 100 mg twice orally after meals daily) over 28 days, with 10 subjects per cohort (8:2 ratio for GST-HG141 and placebo).
