This research is aimed at selecting specific aptamer of hepatitis B e antigen by SELEX and its applications. Hepatitis B e antigen (HBeAg) seroconversion is used as an indicator of virological response when treating patients suffering from chronic hepatitis B. HBeAg also indicates a high viremia and high infectivity in untreated patients. With HBeAg modified magnetic beads as targets, three gro...

BACKGROUND The kinetics of hepatitis B surface antigen (HBsAg) are predictive in HBV-infected patients treated with pegylated interferon. Knowledge about the value of HBsAg levels in patients coinfected with HBV and human immunodeficiency virus (HIV) is lacking. METHODS We quantified serum HBsAg in a Dutch multicenter cohort of 104 patients coinfected with HIV and HBV who were treated with te...

BACKGROUND Chronic hepatitis B consists of different clinical phases. Laboratory and histological assessments can help differentiate the clinical phases of this disease and thus lead to better management. OBJECTIVES This study was conducted to determine laboratory and histological characteristics of HBeAg-negative and HBeAg-positive chronic hepatitis B patients. PATIENTS AND METHODS In this...

Information on the efficacy of pegylated interferon (PEG-IFN) treatment of chronic hepatitis B (CHB) patients and predictors of the response based on real-world data is limited. Consecutive 201 patients who underwent PEG-IFN treatment for CHB were reviewed. A virological response (VR) was defined as a serum HBV DNA of <2000 IU/mL, and a combined response (CR) was defined a VR accompanied by ser...

AIM   The impact of hepatitis B e-antigen (HBeAg) on recurrence of hepatocellular carcinoma (HCC) after curative resection remains controversial. This meta-analysis aimed to determine whether the presence of HBeAg influenced the recurrence of HCC after curative resection. METHODS   We performed a meta-analysis including six studies (a total of 865 patients) to assess the effect of HBeAg on re...

Introduction: According to the WHO, Chad is located in an area of high endemicity for hepatitis B virus (HBV). The aim this study was analyze virological profiles chronic HBV carriers. Materials and Method: This a retrospective analytical including outpatients with any age received Department Internal Medicine Gastroenterology National General Reference Hospital N’Djamena from 2013 2017. Result...

PURPOSE Hepatitis B viral markers may be useful for predicting outcomes such as liver-related deaths or development of hepatocellular carcinoma. We determined the frequency of these markers in different clinical stages of chronic hepatitis B infection. METHODS We compared baseline hepatitis B viral markers in 317 patients who were enrolled in a prospective study and identified the frequency o...

AIM The hepatitis B virus (HBV) is an important healthcare problem. Chronic hepatitis B infection may present with a wide range of manifestations from inactive carrier state to cirrhosis and hepatocellular cancer. Therefore, treatment is very important in chronic hepatitis B. In this study, the treatment results of 199 chronic hepatitis B patients taking entecavir 0.5 mg/day for 48 weeks were e...

The function of the hepatitis B virus (HBV) precore or HBeAg is largely unknown because it is not required for viral assembly, infection, or replication. However, the HBeAg does appear to play a role in viral persistence. It has been suggested that the HBeAg may promote HBV chronicity by functioning as an immunoregulatory protein. As a model of chronic HBeAg exposure and to examine the toleroge...
