Cytokine assays of host immune responses to vaccination can indicate vaccine efficacy. Here we tested the hypothesis that assays of the cytokine status of infected individuals prior to therapeutic vaccination might provide a guide to vaccine therapeutic efficacy. If so, cytokine analysis might be used to select appropriate patients for therapeutic vaccination. Data were obtained from a panel of 14 cytokine/chemokine assays that were done during a phase III clinical trial of HBsAg-HBIG therapeutic vaccine (YIC) treatment of chronic hepatitis B (CHB) patients...

Chronic hepatitis B (CHB) exhibits a variety of clinical outcomes, ranging from spontaneous resolution of hepatitis B to severe adverse consequences, including the development of cirrhosis, hepatic failure, and hepatocellular carcinoma. The heterogeneous clinical courses of chronic hepatitis B virus (HBV) infection reflect the complex host-virus interactions, and point to the difficulty and necessity of identifying the patients at risk. With the advance of HBV virology, several viral factors have been found to be associated with the long-term clinical outcomes of CHB patients...

Chronic hepatitis B (CHB) has become a treatable and controllable disease. The current nucleos(t)ide analogue (NUC) and pegylated interferon therapies effectively help slow disease progression and reduce the risk of cirrhosis, hepatocellular carcinoma (HCC), and CHB-associated mortality. Long-term viral suppression is easily achievable by NUC therapy, with limited adverse reactions. However, several unmet requirements still exist, including safety and risk-stratified HCC surveillance among patients who received long-term NUC therapy...

Chronic hepatitis B virus (HBV) infection is a global public health issue. There are >250 million people chronically infected with HBV, and these chronic carriers are at high risk of developing end-stage liver diseases and hepatocellular carcinoma. Patients with chronic hepatitis B (CHB) usually acquire the virus perinatally, while most patients infected during adulthood develop acute hepatitis B (AHB), which usually results in viral clearance. HBV infection is noncytopathic, and liver injury is mostly contributed by host immune responses...

Interferon-alpha (IFN-α) therapy of chronic hepatitis B (CHB) patients is constrained by limited response and side effects. We described a panel of circulating microRNAs (miRNAs) which could potentially predict outcome of IFN-α therapy. Here, we report development of a simplified scoring model for personalized treatment of CHB patients. 112 CHB patients receiving IFN-α treatment were randomly divided into a training (n = 75) or a validation group (n = 37). The expression of 15 candidate miRNAs was detected in training group with 5 miRNAs exhibiting significantly different levels (p < 0...

IL-18 polymorphisms influence the transcriptional activity of the IL-18 gene and associated with various diseases. However, their relationships with hepatitis B virus-related liver diseases had not reached a consensus. So we conducted this case-control study with a view to clarifying the association. We included four groups: healthy controls, chronic hepatitis B virus (CHB) carriers, liver cirrhosis (LC) and hepatocellular carcinoma (HCC) groups with each group of 250 persons. Odd ratios (ORs) and 95% confidence intervals (95%CIs) with or without adjustment were calculated...

As one of the major global public health concerns, hepatitis B virus (HBV) can be divided into at least eight genotypes, which may be related to disease severity and treatment response. We previously demonstrated that genotypes B and C HBV, with distinct geographical distribution in China, had divergent genotype-dependent amino acid polymorphisms and variations in reverse transcriptase (RT) gene region, a target of antiviral therapy using nucleos(t)ide analogues. Recently recombination between HBV genotypes B and C was reported to occur in the RT region...
