Filter by:The aim of this study is to examine the result of seroprotection using the accelerated vaccination schedule in vaccination of hemodialysis patient through using combined hepatitis A and B vaccine.
The purpose of this study is to recruit a random and representative sample of individuals within several Zambian communities for markers of Hepatitis B Virus (HBV) and to characterize chronic HBV infection and indications for treatment.
This is a Phase 2a, multi-center, randomized, double-blind, placebo-controlled study evaluating the safety, efficacy, and pharmacokinetics (PK) of AL-3778 in combination with Peg-IFN in subjects with Hepatitis B e antigen (HBeAg) positive CHB virus infection who are treatment-naïve. The study will consist of a screening phase , a double-blind treatment phase followed by treatment with Peg-IFN alone, and a post-treatment follow-up phase. Approximately 30 subjects to complete the study. Eligible subjects will be randomized into 2 treatment arms in a 2:1 ratio (active:placebo) to receive one of the following treatments: - Arm A: Peg-IFN plus AL-3778 (N=20) - Arm B: Peg-IFN plus matching placebo (N=10)
- Study population:Person with HBeAg negative CHB on TDF/ETV for more than 1 year - Study design:Prospective,Interventional (single arm study) - Sample size: All the patients fulfilling the inclusion criteria will be included in first 6 months and subsequently followed up for 2 years - Intervention: Peg IFN 2b 1.5mcg/kg once every week for 48 weeks - Monitoring and assessment: LFT,HBV DNA and HbsAg at baseline, 4 weeks, 12 weeks,24 weeks,48 weeks ,72 weeks and 96 weeks, CBC every month and Thyroid function Test every 3rd month - Adverse effects: The most frequently reported side effects of IFN-based therapy are flu-like symptoms, headache, fatigue, myalgia, alopecia, and local reaction at the injection site. Peg-IFN have myelosuppressive effects; however, neutropenia\1000/mm3 and thrombocytopenia \500,000/ mm3 are not common unless patients already have cirrhosis
The DxN Hepatitis B Virus (HBV) Assay is an in vitro diagnostic assay intended as an aid in the management of HBV-infected individuals undergoing antiviral therapy. The purpose of the study is to establish the clinical performance of the DxN HBV Assay for plasma samples in the intended use population.
The investigators aim at describing changes in renal glomerular and tubular function with after the switch from TDF to TAF in HIV/HBV-coinfected patients with mild to moderate renal dysfunction and to assess the virological efficacy of TAF on HBV infection. The study will include HIV/HBV-coinfected participants of the Swiss HIV Cohort Study (SHCS) who are under active care and have been on a stable, TDF-containing ART regimen for at least 6 months. Only patients with an estimated glomerular filtration rate (GFR) between 30 ml/min and 90 ml/min will be included. All individuals who agree to participate will be switched from a TDF-containing ART regimen to a TAF-containing triple ART regimen at week 0 and will be followed for 48 weeks after the treatment change.
To evaluate the safety and anti-HBV efficacy of γδT cells.
The purpose of this protocol is to obtain pharmacodynamic and pharmacokinetic data on ABI-H0731 and to provide the opportunity for preliminary evaluation of combination therapy of ABI-H0731 with currently approved antiviral treatment for chronic hepatitis B.
CR-HepB registry started in June 30,2012 to collect HBV cases from general hospitals or specialized hospitals for infectious diseases in mainland China. Demographics, diagnosis, laboratory test results, family history and prescriptions were recorded. The main criteria for registration is HBsAg-positivity more than 6 months, and these patients will receive followed-up visits every three to six months.
Hepatitis B virus (HBV) infection remains one of the most serious health problems worldwide. Patients with chronic HBV infection are at an increased risk for developing hepatic cirrhosis, hepatocellular carcinoma and even death. Although some predictive factors of the outcome of chronic HBV infection were identified, more precisely determine the factors which are associated with the outcome in non-selected patients with chronic HBV infection are still needed. The investigators purpose is to constitute a observational cohort of non-selected Chinese patients to create a database of epidemiological, clinical, biological, virological, immunologic and therapeutic parameters, in order to determine factors associated with the outcome of chronic HBV infection.
