Filter by:This study is a retrospective analysis to explore the incidence of hepatitis B virus reactivation after withdrawal of prophylactic antiviral therapy, the efficacy and safety of chemotherapy, and overall survival rate in lymphoma patients with hepatitis B virus infection.
A randomized, Open label, Single center, Prospective study to compare efficacy and safety of Therapeutic Vaccination with Intensified schedule plus Pegylated Interferon dual Therapy on Seroclearance of Hepatitis B virus Surface Antigen in Patients with Complete Virological Response Induced by Entecavir
The purpose of this study is to assess the immunogenicity and safety of GSK Biologicals' Infanrix hexa vaccine when administered to healthy infants as primary vaccination at 2, 4 and 6 months of age, co-administered with Prevnar and Rotarix with a booster dose of GSK Biologicals' Infanrix and Hiberix vaccines at 15-18 months of age.
The aim of this study is to evaluate the immunogenicity and safety of a novel DTaP-IPV-Hep B-PRP~T fully liquid combined hexavalent vaccine (study vaccine) administered at 2, 4, and 6 months of age compared to Sanofi Pasteur's DTaP-IPV//PRP~T combined vaccine (Pentaxim™) given at 2, 4, and 6 months of age and Hep B vaccine (Euvax B®) given at 1 and 6 months of age in South Korean infants that received a birth dose of Hep B and born to mothers documented to be serum anti-HBs Ag negative. Primary Objective - To demonstrate the non-inferiority in terms of seroprotection (Diphtheria, Tetanus, poliovirus types 1, 2, and 3, PRP-T, Hep B) and vaccine response for pertussis antigens (pertussis toxoid [PT] and filamentous haemagglutinin [FHA]) of Group A versus Group B, one month after the third dose of combined vaccines. Secondary Objectives: - To further study the immunogenicity of the two vaccination schemes, before the first dose and one month after the last dose of vaccines. - To study the safety after each and any dose of vaccines administered in the two vaccination schemes
To evaluate the effectiveness and safety of tenofovir for different treatment duration in preventing HBV relapse in patients with malignancies after receiving chemotherapy and off-treatment of chemotherapy.
It is estimated that 350-400 million people have chronic infection with hepatitis B virus (HBV) all over the world. In china, 93 million individuals suffer from this chronic condition. Currently, seven medications are approved for the treatment of hepatitis B: two formulations of interferon and four nucleos(t)ide analogues. The Chinese population has one of the longer average life spans, and the size of the aged population has been increasing rapidly. As a result, the prevalence of elderly patients with HBV has increased, and the potential for development of cirrhosis or hepatocellular carcinoma in such patients is real. Hence, treatment of elderly patients with HBV is an important issue. However, ADV or ETV has become first choice due to the more side effect of INF and the resistant of LAM and LdT. But treatment outcomes with ADV and ETV in elderly are not known yet. In this study, we will evaluate and compare the efficacy and tolerability of ADV and ETV between younger and older patients with HBV. The aims of the present study are (1)to assess the benefits of ADV or ETV therapy for elderly patients with chronic hepatitis B, and (2)to determine differences in the emergence rate of side effect.
This study will assess the efficacy, safety, and tolerability of elvitegravir/cobicistat/emtricitabine/tenofovir alafenamide (E/C/F/TAF) fixed-dose combination (FDC) in human immunodeficiency virus (HIV)/hepatitis B virus (HBV) coinfected adults. Participants will be enrolled into two cohorts: - Cohort 1: HIV/HBV coinfected adults who are HIV treatment-naive and HBV treatment-naive - Cohort 2: HIV/HBV coinfected adults who are HIV-suppressed
This will be a multi-center study in Hong Kong. This is a retrospective-prospective study in HBeAg-negative chronic hepatitis B patients. HBeAg-negative patients on entecavir followed up in the liver clinics will be identified from the existing database. All patients had HBV DNA testing every 6 months as a clinic routine. Serum HBsAg levels will be tested in the residual serum samples at the pre-treatment and last follow-up visits. Eligible patients will be discussed on the plan of stopping entecavir therapy. All patients will have written informed consent before recruited into this study. All patients will be followed up for 12 months after stopping entecavir treatment. As entecavir is most commonly used antiviral drug in Hong Kong and in the Western countries, the investigators aim to investigate and validate the use of serum HBsAg quantification to guide the timing of stopping entecavir in HBeAg-negative patients. The results of this study will provide scientific evidence on the use of this new serum marker to predict sustained remission after stopping entecavir. In the long-run, it can improve patient compliance, reduce the need of long-term antiviral and reduce the drug cost in the management of HBeAg-negative chronic hepatitis B. All patients will stop entecavir according to the Asian Pacific guideline with written informed consent and close subsequent monitoring. In the protocol, there is a safety net for re-treatment. There will not be any invasive procedure. There is no major ethical issue.
This is a multi-center, single-arm, open-label study on the virological response of chronic HBV infection to pegyinterferon-alfa-2a among patients who achieved HBeAg seroconversion on nucleos(t)ide analogue (NA) treatment. The primary endpoint of this study is to investigate the sustained response (HBeAg seroconversion with HBV DNA <2000 IU/ml) to peginterferon at 24 weeks after the end of treatment.
This is a prospective HIV cohort that aims to establish causes of liver disease among HIV-infected individuals in Zambia, including viral hepatitis and alcohol.
