Maintaining Antiviral Efficacy After Switching to Generic Entecavir 1 mg for Chronic Hepatitis B...
Chronic Hepatitis BEntecavir 1 mg is commonly used in patients with chronic hepatitis B (CHB) patients with previous antiviral resistance. This study evaluates the efficacy and safety of switching to generic entecavir 1 mg (Baracle®, Dong-A Science Technology) in CHB patients taking brand name entecavir 1 mg (Baraclude®, Bristol-Myers Squibb) alone or in combination with other nucleos(t)ide analogues after the development of antiviral resistance. The primary aim is virological response (<20 IU/mL) at 12 months

The Investigation of Peginterferon Alfa-2a on the RFS of the Subjects With HCC Who Have Been Treated...
Chronic Hepatitis bHepatic CarcinomaThe current study is a prospective, randomized, open, multi-center investigation. The aim of current study is to investigate whether the Recurrence-free Survival Rate (RFS)of the hepatitis B related -hepatocellular carcinoma subjects who have been treated by resection can be improved by peginterferon alfa-2a

The Changes of CD4+T Cells Frequency and Function During Antiviral Therapy
Chronic Hepatitis B InfectionPegylated interferon α-2a(Peg-IFN-α) not only inhibit viral replication, but also play an important role in immune regulation, while Nucleoside analog(ue) drugs only inhibit viral replication. In hepatitis B infection, CD4+T Cells are the main effector cells in adaptive immune response. This study was aimed at investigating the changes of CD4+T Cells frequency and function, and the expression of costimulatory molecules during Peg-IFN-αand nucleoside analog(ue) therapy.Meanwhile, the investigators want to verify whether Peg IFN - alpha suppressed the virus and the reduction of virus led to the recovery of CD4+T Cells function, or Peg IFN - alpha enhanced CD4+T Cells function which gave rise to the decline of the virus.

Tenofovir Monotherapy in Patients With Chronic Hepatitis B Patients Who Had Achieved Complete Viral...
Proportion of Patients With a Sustained Virological Response (Serum HBV DNA <20 IU/mL) at Week 48Little is known about efficacy of switching to tenofovir monotherapy for lam-resistant chronic hepatitis B patients who achieved a complete virological response to lamivudine plus adefovir. This study was to investigate the efficacy of switching to tenofovir monotherapy for lamivudine -resistant chronic hepatitis B patients with undetectable hepatitis B virus DNA while on lamivudine plus adefovir combination therapy

Proportion of Patients With a Sustained Virological Response (Serum HBV DNA <20 IU/mL) at Week 48Little is known about efficacy of switching to tenofovir monotherapy for multidrug-resistant chronic ehpatitis B patients who achieved a complete virological response to entecavir and tenofovir. This study aimed to investigate the efficacy of switching to tenofovir monotherapy for multidrug-resistant chronic hepatitis B patients with undetectable heaptitis B virus DNA while on tenofovir plus entecavir combination therapy.

Use of Dynavax Heplisav B in Healthcare Workers Previously Vaccinated With 3-dose Vaccine Who Failed...
Hepatitis B VirusProtection against Hepatitis B infection is a regulatory and safety cornerstone to infection prevention and control programs involving the healthcare workforce in the United States. Until 2018 when a new adjuvanted vaccine was released, immunization for this population has involved a three-dose series followed by an additional three-dose series for those demonstrating lack of seroprotection. If that lack continued following the second three-dose series, and verification of a negative Hepatitis B antigen status, that person has historically been deemed a non-responder to Hepatitis B vaccine and at potential risk for infection. This non-response status may be used to determine job responsibilities representing excessive risk for the healthcare worker resulting in potential career and practice limitations and decisions. With the release of the new adjuvanted vaccine, there is potential to determine the role that new vaccine may play in promoting an immune response among this non-responding subset of at-risk healthcare workers. The aims of this study include: 1) determining the effect of this adjuvanted vaccine in producing seropositivity in a population of healthcare personnel previously deemed as non-responders following administration of two rounds of the traditional 3-dose series of Hepatitis B vaccine and confirmation of negative Hepatitis B antigen; and 2) determining the personal and professional impact of the lack of immunity to Hepatitis B among healthcare personnel.
