Hepatocellular carcinoma (HCC) is a major malignant disease worldwide, and chronic hepatitis B virus (HBV) infection is one of the primary causes for this type of cancer. Hepatitis B virus X protein (HBx) is a non-structural protein encoded by the viral genome that has significant effects on the pathogenesis of HCC. With the development of high-throughput assays and technologies, the abnormal HBx-induced expression of certain cellular proteins with assorted biological functions has been investigated. These target proteins identified by various methods include specific proteins associated with the cellular cytoskeleton, which contribute to HBx-induced hepatocarcinogenesis...

A therapeutic vaccine is meant to activate the patient's immune system to fight and finally control or ideally eliminate an already established infectious pathogen. Whereas the success of prophylactic vaccination is based on rapid antibody-mediated neutralization of an invading pathogen, control and elimination of persistent viruses such as hepatitis, herpes or papilloma viruses requires multi-specific and polyfunctional effector T cell responses. These are ideally directed against continuously expressed viral antigens to keep the pathogen in check...

BACKGROUND: Previous studies have noted significant gender difference in the risk of liver cancer among hepatitis B chronic infection patients. Some indicated that it might be due to lifestyle-related differences. This paper tests whether or not such a gender discrepancy among the chronic hepatitis B population is confounded by lifestyle and environment related exposures. METHODS: We retrieved a sample of 1863 participants from a prospective cohort in Haimen City, China in 2003...

We thank Ricceri et al. for their comments (1) and interest in our study (2). Despite the recent advances in prevention and treatment of hepatitis B virus (HBV) and hepatitis C virus (HCV) infections, these two chronic infections still represent the most common cause of chronic liver disease. Dermatologists are frequently encountering patients with psoriatic disease who have concomitant HBV or HCV infection in daily clinical practice. Dr Ricceri provided in his letter further long-term follow-up data (60 months) on the use of etanercept or adalimumab in 17 psoriatic patients affected by past HBV infection or chronic HCV infection...

We have read with interest the article by Piaserico et al. concerning the use of tumour necrosis factor-alpha (TNF-alpha) blocking agent adalimumab in psoriatic patients with concomitant hepatitis B virus (HBV) or hepatitis C virus (HCV). The authors describe 17 psoriatic patients affected by chronic HBV infection and 20 affected by chronic HCV who were successfully treated with adalimumab with no evidence of HBV or HCV reactivation in a mean follow-up period of 27 and 40 months, respectively. We have previously described our successful experience of treatment with anti-TNF-alpha therapy in 17 psoriatic patients (11 with past HBV infection, 5 with chronic HCV infection and one affected by both HBV and HCV) without the use of lamivudine or adenofovir, and can now report on long-term follow-up data (mean follow-up period of 60 months)...

Histone acetylation has been demonstrated to serve a pivotal role in numerous inflammatory diseases. The present study examined histone acetylation in patients with chronic hepatitis B (CHB) and CHB with liver failure by detecting histone deacetylase (HDAC) activity. Mice with acute liver failure (ALF) were treated with the HDAC inhibitor entinostat (MS275) and alterations in HDAC activity and pro‑inflammatory cytokine expression levels were detected. The effect of HDAC1 silencing on LPS-treated RAW264.7 murine macrophages was examined using specific small interfering RNA sequences, and the acetylation level of the non‑histone nuclear factor‑κB (NF‑κB) p65 subunit was additionally examined...

Strong tolerance to HBV surface antigens limits the therapeutic effect of the conventional HBsAg vaccination in both preclinical animal models and patients with chronic hepatitis B (CHB) infection. In contrast, we observed that clinical CHB patients presented less immune tolerance to the preS1 domain of HBV large surface antigen. To study whether targeting the weak tolerance of preS1 region could improve therapy gain, we explored vaccination with the long peptide of preS1 domain for HBV virions clearance. Our study showed that this preS1-polypeptide rather than HBsAg vaccination induced robust immune responses in the HBV carrier mice...

Chronic Hepatitis B Virus (HBV) infection is a major risk factor for hepatocellular carcinoma (HCC) and current treatments for CHB and HCC are perfectible. Herein, we identified cellular Serine/Threonine Polo-like-kinase 1 (PLK1) as a positive effector of HBV replication. The aim of this study was to demonstrate the proviral role of PLK1 in HBV biosynthesis and validate PLK1 inhibition a potential antiviral strategy. To this end, we employed physiologically relevant HBV infection models of Primary Human Hepatocytes (PHH) and differentiated HepaRG cells, in conjunction with pharmacologic PLK1 inhibitors, siRNA-mediated knockdown, and overexpression of constitutively active PLK1 (PLK1(CA) )...

Quantum dots (QDs) are semiconductor nanoparticles with a diameter of less than 10 nm, which have been widely used as fluorescent probes in biochemical analysis and vivo imaging because of their excellent optical properties. Sensitive and convenient detection of hepatitis B virus (HBV) gene mutations is important in clinical diagnosis. Therefore, we developed a sensitive, low-cost and convenient QDs-mediated fluorescent method for the detection of HBV gene mutations in real serum samples from chronic hepatitis B (CHB) patients who had received lamivudine or telbivudine antiviral therapy...

Acute-on-chronic liver failure (ACLF) in chronic hepatitis B (CHB) patients has a high short-term mortality. Identification of effective models to predict the short-term mortality may enable early intervention and improve patients' prognosis. We aim to assess the performance of the CLIF Consortium Organ Failure score (CLIF-C OFs), CLIF sequential organ failure assessment score (CLIF-SOFAs), CLIF Consortium ACLF score (CLIF-C ACLFs), ACLF grade, and model for end-stage liver disease score (MELDs) in predicting the short-term mortality in CHB patients with ACLF...

Chronic liver diseases (CLDs), due to chronic hepatitis C; hepatitis B; nonalcoholic fatty liver diseases (NAFLD); and alcoholic liver disease, are a leading cause of morbidity and mortality globally. Early identification of patients with cirrhosis at high risk of progression to liver-related complications may facilitate timely care and improve outcomes. With risks and misclassification associated with invasive tests, such as liver biopsy, noninvasive imaging modalities for liver fibrosis assessment have gained popularity...

BACKGROUND: High genetic variability at reverse transcriptase (RT) region of hepatitis B virus (HBV) could confer resistance to nucleos(t)ide analogues (NUCs). The aim of this study was to identify new RT amino acid (AA) substitutions related to NUCs resistance. METHODS: HBV RT sequences of genotype C from 501 chronic hepatitis B (CHB) patients were analyzed to identify potential RT substitutions related to NUCs resistance. In vitro studies without and with NUCs were performed in HepG2 cell line transfected by clones with RT harboring wild-type or substituted AA(s) of interest...

Let-7a miRNA is downregulated in various cancers. However, in hepatocellular carcinoma (HCC) patients infected with hepatitis B virus (HBV), the relationship between let-7a and HBV replication has not been fully elucidated. Liver specimens were collected from 23 HCC patients with chronically active HBV. The serum levels of the HBV antigens hepatitis B surface antigen (HBsAg) and hepatitis B virus e antigen (HBeAg), and the HBV antibodies, anti-HBs, anti-HBe and anti-hepatitis B core antigen (anti-HBc) were measured using the microparticle enzyme immunoassay...

Background: Direct-acting antiviral agents (DAAs) are used increasingly to treat hepatitis C virus (HCV) infection. Reports were published recently on hepatitis B virus (HBV) reactivation (HBV-R) in patients with HBV-HCV co-infection. Hepatitis B virus reactivation, defined as an abrupt increase in HBV replication in patients with inactive or resolved HBV infection, may result in clinically significant hepatitis. Objective: To assess whether HBV-R is a safety concern in patients receiving HCV DAAs...

All patients with chronic hepatitis C virus (HCV) infections can and should be treated. Though highly effective direct-acting antiviral therapies are costly, the price of a cure is a 1-time investment that is outweighed by future benefits. For clinicians caring for patients requiring liver transplant, the key question relates to the timing of treatment: before or after liver transplantation? On 1 hand, treating HCV often improves our patients' model for end-stage liver disease (MELD) score, decreasing costs, and potentially improving longevity by reducing our patients' risk of death and transplantation...
