Filter by:The purpose of this study is to identify the effect of prophylactic entecavir in HBsAg Negative/HBcAb Positive/hepatitis B virus DNA Negative patients with lymphoma.
This study is aimed to assess the efficacy and safety of Peginterferon alfa-2b (40kD, Y-shape), in a dose of 180μg/week, in chronic hepatitis B patients, and collects sufficient evidences for the listed of the studied drug.
Chronic hepatitis B (CHB) infection is complicated by cirrhosis and liver cancer. In Thailand, 7% of adults are chronically infected by Hepatitis B virus (HBV). The risk of perinatal transmission of HBV is about 12% when a mother has a high HBV load in her plasma, even if her infant receive specific immunoglobulin and vaccine. The hypothesis of this study is that a potent antiviral, tenofovir, can decrease HBV load in HBV infected pregnant women and therefore reduce the risk of perinatal transmission/ Pregnant women participating in this study will receive tenofovir or placebo during the last trimester of pregnancy and two months postpartum. The risk of perinatal transmission will be compared between the two groups. The results of the study will help define policy to manage HBV infected pregnant women to prevent perinatal transmission.
The purpose of this study is to evaluate the efficacy and safety of telbivudine and lamivudine use during late pregnancy for the prevention of HBV perinatal transmission in highly viraemic mothers.
This multicenter, prospective, observational study will evaluate the efficacy and safety of Pegasys (peginterferon alfa-2a) in routine clinical practice in patients with HBeAg-positive or HBeAg-negative chronic hepatitis B. Eligible patients receiving treatment with Pegasys according to standard of care and the summary od product characteristics/local labelling will be followed for the duration of treatment and up to 2 years of follow-up.
This study will provide a rationale for switch from lamivudine plus adefovir to tenofovir monotherapy in Lamivudine plus Adefovir Treated Lamivudine-resistant chronic hepatitis B patients with Undetectable Hepatitis B Virus DNA
The investigators aim to clarify the issue of adequate duration of consolidation period of Chronic hepatitis B infection with antiviral treatment with Tenofovir which could strike a balance between durable HBeAg seroconversion and avoiding long-term inevitable serological or virological recurrence.
The relevant data will be prospectively collected included patient demographics, clinical, all laboratory variables including virological tests, genotyping by direct sequencing, abdominal ultrasound, and upper gastrointestinal (GI) endoscopy. Trans jugular liver biopsy (TJLB) and hepatic venous pressure gradient (HVPG) will be done in patients when it was not evident whether the underlying liver disease was chronic based on clinical, biochemical, radiological investigations, and upper GI endoscopy. Severity of the liver disease will be assessed by Child-Turcotte Pugh score (CTP) and model for end stage liver disease (MELD) score.
It is estimated that 350-400 million people worldwide are chronically infected with hepatitis B virus (HBV). Cirrhosis and hepatocellular carcinoma are major complications of chronic HBV infection and are responsible of about 500,000 deaths each year. Although some predictive factors of the outcome of chronic HBV infection were reported, it remains needed to more precisely determine the factors which are associated with the outcome in non-selected patients. Indeed, these factors should help to identify patients who are likely to have a better or worse evolution of their chronic HBV infection over time and thus, to adapt their clinical management and monitoring.Therefore, our purpose is to constitute a "real-life" cohort of non-selected patients to create a database of epidemiological, clinical, biological, virological and therapeutic parameters, in order to determine factors associated with the outcome of chronic HBV infection.
This multicenter, prospective, observational study will evaluate the use in clinical practice and the efficacy and safety of Pegasys (peginterferon alfa-2a) in Chinese participants with HBeAg negative chronic hepatitis B. Participants receiving Pegasys according to the local label will be followed for the duration of their treatment and for one year after cessation of treatment.
