In recent decades, microRNAs (miRNAs) have emerged as key regulators of gene expression, and the identification of viral miRNAs (v-miRNAs) within some viruses, including hepatitis B virus (HBV), has attracted significant attention. HBV infections often progress to chronic states (CHB) and may induce fibrosis/cirrhosis and hepatocellular carcinoma (HCC). The presence of HBV can dysregulate host miRNA expression, influencing several biological pathways, such as apoptosis, innate and immune response, viral replication, and pathogenesis. Consequently, miRNAs are considered a promising biomarker for diagnostic, prognostic, and treatment response. The dynamics of miRNAs during HBV infection are multifaceted, influenced by host variability and miRNA interactions. Given the ability of miRNAs to target multiple messenger RNA (mRNA), understanding the viral-host (human) interplay is complex but essential to develop novel clinical applications. Therefore, bioinformatics can help to analyze, identify, and interpret a vast amount of miRNA data. This review explores the bioinformatics tools available for viral and host miRNA research. Moreover, we introduce a brief overview focusing on the role of miRNAs during HBV infection. In this way, this review aims to help the selection of the most appropriate bioinformatics tools based on requirements and research goals.

Disulfiram (DSF), an FDA-approved therapeutic agent for alcohol dependence, has recently attracted considerable interest due to its broad-spectrum inhibitory effects against various viruses. Increasing evidence suggests that DSF can inhibit viral replication through two major mechanisms: the inhibition of viral protein catalytic activity and the ejection of Zn from viral proteins. This review comprehensively summarized the molecular mechanisms underlying DSF's antiviral activity against viruses such as severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), hepatitis C virus (HCV), influenza virus, human immunodeficiency virus (HIV), and Kaposi sarcoma-associated herpes virus (KSHV), with a particular focus on its dual targeting of Cys residues and Zn coordination sites.

Direct-acting antivirals (DAAs) have transformed hepatitis C virus (HCV) treatment in Australia since their inclusion on the Pharmaceutical Benefits Scheme (PBS) in 2016. Treatment has shifted from genotype-specific to pan-genotypic regimens, with glecaprevir/pibrentasvir and sofosbuvir/velpatasvir now recommended in clinical guidelines. This study examined trends in DAA dispensing in light of evolving treatment regimens.

Background And Aims: Sofosbuvir (SOF) plus daclatasvir (DCV) is a primary chronic hepatitis C virus (HCV) treatment in low- and middle-income countries. WHO guidelines recommend a half-adult dose for children (14-25 kg) based on pharmacokinetic modelling, requiring clinical validation. We evaluated the pharmacokinetics, safety, efficacy and acceptability of DCV (30 mg) and SOF (200 mg) in children weighing 14 to < 17 kg and 17-35 kg.

Background: Current and past hepatitis B virus (HBV) infection remains the leading cause of liver cancer in endemic areas.
Aim: To examine the risk of HBV reactivation (HBVr) in patients receiving immune checkpoint inhibitors (ICI) for liver cancer.
Methods: Patients with current or past HBV infection receiving systemic treatments for liver cancer from March 2015 to March 2023 were identified using a territory-wide electronic database in Hong Kong.

Coinfection of humans with Hepatitis B Virus (HBV) and non-viral pathogens may worsen the outcome of HBV infection on the liver. This study determined the prevalence of Heliobacter pylori, Salmonella typhi, Plasmodium falciparum, and Toxoplasma gondii among Hepatitis B Virus (HBV)-infected persons in the Greater Accra Region (GAR) of Ghana and examined how such co-infections might affect the levels of selected liver function markers (LFM). The design was cross-sectional, involving 120 HBsAg-positive HBV-infected persons.
