Hepatitis B virus (HBV) RNA in serum is a novel biomarker for intrahepatic HBV replication and treatment response. For its proper use it is essential to identify factors influencing serum HBV RNA level. Using a RACE PCR technique (lower limit of detection 800 copies/mL [c/mL]), serum HBV RNA levels were measured in samples of 488 untreated individuals with chronic HBV infection who were eligible to treatment according to currently used recommendations. We explored the association of serum levels of HBV RNA with patient and virus associated factors...

AIM: Chronic hepatitis B (CHB) is a global health problem. Recent genome-wide association studies (GWAS) exposed signifi-cant association between the human leukocyte antigen (HLA) class II region, including both DP and DQ loci, and chronic hepatitis B. Previous research also indicated the involvement of adaptive immune system in Hepatitis B seroconversion. The aim of this study is to investigate possible polymorphisms in the HLA-DP locus that can contribute to immune response to Hepatitis B virus (HBV)...

Background: Chronic hepatitis B (CHB) remains a global health dilemma with high morbidity and mortality. Human males absent on the first (hMOF) (a histone acetyltransferase) is responsible for DNA damage repair, tumorigenesis and cell cycle regulation. Persistence of HBV DNA contributes to cirrhosis and hepatocellular carcinoma (HCC) in CHB patients. Histone acetyltransferase enhances HBV replication, however the precise underlying mechanism of hMOF in HBV replication in CHB patients remains to be explored...

African-Australians have a high prevalence of chronic hepatitis B (CHB) and an increased risk of liver cancer (hepatocellular carcinoma, HCC) at a younger age than other affected groups living with CHB. The prevention of HCC-related mortality is possible with timely diagnosis of CHB, regular monitoring including liver cancer surveillance and appropriate treatment with antiviral therapy. Currently, little is known about how African-Australians living with CHB understand their condition, their risk of liver cancer and the need for regular monitoring...

Hepatitis B virus (HBV) infection is a common problem in the world, especially in China. More than 60-80% of hepatocellular carcinoma (HCC) cases can be attributed to HBV infection in high HBV prevalent regions. Although traditional Sanger sequencing has been extensively used to investigate HBV sequences, NGS is becoming more commonly used. Further, it is unknown whether word pattern frequencies of HBV reads by Next Generation Sequencing (NGS) can be used to investigate HBV genotypes and predict HCC status...

Background: Treatment with nucleos(t)ide analogues (NA) efficiently suppress HBV DNA but rarely leads to functional cure of chronic hepatitis B (CHB). Following NA cessation, a fraction of HBeAg-negative CHB-patients experience HBsAg loss. Cellular immune responses, including those by natural killer cells, innate lymphocytes known to respond in CHB, explaining the virological events transpiring following NA treatment cessation remain elusive. Methods: In a single-center prospective trial, 15 HBeAg-negative CHB-patients on long-term NA treatment underwent structured NA cessation and were studied longitudinally...
