Hepatitis B virus (HBV) infection led to 66% liver deaths world-wide in year 2015. Thirty-seven per cent of these deaths were the result of chronic hepatitis B (CHB)-associated hepatocellular carcinoma (HCC). Although early diagnosis of HCC improves survival, early detection is rare. Methylation of HBV DNA including covalently closed circular DNA (cccDNA) is more often encountered in HCC cases than those in CHB and cirrhosis. Three typical CpG islands within the HBV genome are the common sites for methylation. The HBV cccDNA methylation affects the viral replication and protein expression in the course of infection and may associate with the disease pathogenesis and HCC development. We review the current findings in HBV DNA methylation that provide insights into its role in HCC diagnosis.

Background: Infection with the human immunodeficiency virus and hepatitis viruses B and C have been reported to be endemic in some Nigeria's institutions of higher learning. Several studies have reported varying prevalence rates for hepatitis B and C viruses and HIV among undergraduate students in Nigerian universities.

Methodology: A cross-sectional descriptive prevalence study of hepatitis B and C viruses and HIV among students at Federal University of Health Sciences, Azare conducted on the 2nd of December 2023.

Background: Hepatitis C virus (HCV) has emerged as a sexually transmitted infection in gay, bisexual, and other men who have sex with men (GBM). We estimated the seroprevalence and incidence of HCV infection and examined patterns of HCV testing among GBM using human immunodeficiency virus preexposure prophylaxis (PrEP) in Ontario, Canada.

Methods: We analyzed data from the Ontario PrEP Cohort Study (ON-PrEP), a prospective cohort of PrEP users from 10 Ontario clinics.

Background: The burden of hepatitis C virus (HCV)-related hospitalizations is substantial, particularly among people with HIV and HCV. In Ontario, Canada, use of direct-acting antivirals (DAAs) increased following policies removing fibrosis-stage restrictions and approving of pangenotypic agents in 2017 and 2018, respectively. We examined the impact of expanded DAA access on HCV-related hospitalizations in people with HIV.

Purpose: The research intended to present prospective data on the long-term prognosis of individuals with hepatitis C virus (HCV) infection who received direct-acting antiviral agent (DAA) treatment.

Patients And Methods: Patients who received DAA treatment at Tianjin Third Central Hospital and Tianjin Second People's Hospital were prospectively enrolled and subsequently underwent a longitudinal follow-up. This research monitored occurrences of virological relapse, hepatocellular carcinoma (HCC), mortality, and liver disease progression.

Progress towards achieving global elimination of hepatitis B virus (HBV) by 2030 remains unsatisfactory. Prevention of mother to child transmission is crucial but current Clinical Practice Guidelines (CPGs) gave diverse recommendations, creating confusion and leading to significant challenges in the practical implementation across various regions owing to global inequity. We reviewed 47 CPGs on the management of hepatitis B during pregnancy against twelve important clinical questions.
