BACKGROUND The quantitation of serum HBeAg is not commonly used to monitor viral response to therapy in chronic hepatitis B. METHODS In this study, 21 patients receiving varying therapies were followed and their viral response monitored by concomitant viral load and HBeAg quantitation in order to study the meaning and the kinetics of both parameters. RESULTS It was possible to distinguish b...
Pathogenic and therapeutic differences among hepatitis B virus (HBV) genotypes have been documented. However, the association of virological characteristics with clinical differences among HBV genotypes remains unclear. We therefore studied the clinical and virological characteristics of Taiwanese volunteer blood donors infected with HBV genotypes B and C. HBV genotypes were determined in 300 c...
Serum samples from a total of 72 chronic hepatitis B virus carriers were analysed by serological, biochemical and molecular assays. The aim was to evaluate the relationship of the serological and biochemical parameters with molecular markers in order to assess the infectivity of virus. Out of 72 chronic HBsAg positive carriers, 28 patients were HBeAg positive and anti-HBe negative, 38 patients ...
OBJECTIVE To evaluate the cost-effectiveness of different drug therapies for chronic hepatitis B in adult patients. METHODS Using a Markov model, a hypothetical cohort of 40 years for HBeAg-positive or HBeAg-negative patients was constructed. Adefovir, entecavir, tenofovir and lamivudine (with rescue therapy in cases of viral resistance) were compared for treating adult patients with chronic ...
BACKGROUND Despite the availability of effective vaccines, hepatitis B virus (HBV) infection is still frequent worldwide, and accounts for significant morbidity and mortality. However, data of acute HBeAg negative hepatitis still remain limited. AIMS AND METHODS To understand clinical pictures of acute HBV hepatitis and its natural evolution, a prospective study was conducted in adult patient...
Results: VR at 48 weeks post-treatment, defined as HBeAg seroconversion and HBV DNA less than 10 000 copies/mL was achieved in 10 (33.3%) patients. Responders had significantly lower baseline HBsAg, HBeAg, cccDNA and intrahepatic HBV DNA levels than non-responders. Baseline and reduced levels of log10 HBsAg and log10 HBeAg correlated well with those of log10 cccDNA and log10 total intrahepatic ...
This study investigated the prevalence of the precore G1896A mutation in Chinese patients with hepatitis B e antigen (HBeAg) negative HBV infection and its relation to serum HBV pre-S1 antigen. The overall prevalence of the precore G1896A mutation was 72.6% in HBeAg-negative Chinese patients with detectable serum HBV DNA. The prevalence of the precore G1896A is significantly higher in Chinese H...
Hepatitis B viral infection is an important clinical problem due to its worldwide distribution and potential of adverse sequelae, including hepatocellular carcinoma (HCC). We studied the prevalence of hepatitis B virus 'e' antigen (HBeAg) among individuals determined to be hepatitis B virus (HBV) surface antigen-positive and analyzed the gender/age category associated with more active HBV infec...
BACKGROUND Hepatitis B virus (HBV) infection is an important health concern worldwide, with critical outcomes. Hepatitis B e antigen (HBeAg) negative chronic hepatitis B is frequently caused by a mutation (G1896A) in the hepatitis B virus (HBV) precore (PC) reading frame, which creates a stop codon, causing premature termination of the HBe protein. OBJECTIVES This study aimed to investigate t...
Hepatitis B e antigen (HBeAg) is believed to be required for the establishment of chronic HBV infection, but the mechanisms remain unknown. Dendritic cells (DCs) are the most potent antigen-presenting cells that play an essential role in the initiation of immune response. And only mature DCs are capable of priming and activating T lymphocytes to induce protective immunity. The aim of this study...
