Novel Long‐Read Sequencing Method for Characterisation of Hepatitis B Transcripts Show High Expression of Chimeric HBV/Human RNA

Liver International, Volume 46, Issue 3, March 2026.
ABSTRACT Background Hepatitis B virus (HBV) genomes integrated into human DNA significantly contribute to surface antigen (HBsAg) production and may drive hepatocellular carcinoma (HCC). Long‐read sequencing methods like Nanopore offer advantages over short‐read next‐generation sequencing (NGS) by providing continuous reads of whole transcripts, but ...

Prevalence and Spectrum of Chronic Liver Disease Among Patients Seeking Health Care in Ghana

Liver International, Volume 46, Issue 3, March 2026.
ABSTRACT Background Chronic liver diseases (CLD) leading to liver fibrosis and cirrhosis are a major cause of morbidity and mortality in sub‐Saharan Africa and pose a significant burden on its health care systems. We aimed to elucidate the prevalence of fibrosis/cirrhosis in patients seeking health care in Kumasi, Ghana, and its underlying aetiologies.

Occult Hepatitis B Virus Infection

Annals of Clinical and Analytical Medicine, 2013
Occult hepatitis B virus infection (OHB) is defined as presence of Hepatitis B Virus (HBV) deoxyribonucleic acid in blood or tissues with undetectable hepatitis B surface antigen, outwith the preseroconversion window period. Several possibilities have been hypothesized as the mechanisms of OHB.
