A Randomized Study Comparing Lamivudine Versus Adefovir Dipivoxil for Prevention of zHBV Reactivation in HBsAg Seropositive Patients Undergoing Cytotoxic Chemotherapy

Liver diseases due to hepatitis B reactivation are serious causes of morbidity and mortality in hepatitis B infected patients treated with chemotherapy. We have previously shown that with pre-emptive use of lamivudine, one can drastically reduce liver-related morbidity and mortality in such patients. However, due to the development of hepatitis ...

Phase N/A

Genetic Susceptibility or Resistance to Hepatitis B Virus in the Chinese Population

OBJECTIVES: - Study how different outcomes of hepatitis B exposure and infection are affected by host genetic factors in the Chinese population. OUTLINE: This is multicenter study. Participants complete health questionnaires about personal and family health history and eating, drinking, and smoking habits. Blood samples from participants are collected and ...

Safety Profiles of Liver Biopsy in Hemodialysis Patients With Chronic Viral Hepatitis Pre-treated With Vasopressin

Chronic viral hepatitis is common in dialysis patients, with the reported prevalence and annual incidence of 3-80% and 2.9%, respectively. Currently, percutaneous liver biopsy (PLB) remains the gold standard for grading necroinflammation and staging fibrosis in patients with liver diseases. In addition, liver histology can help clinicians determine the eligibility ...

Prevention of Graft Reinfection After Liver Transplantation With Anti HCV Monoclonal Antibodies Identified in Chronically Infected Patients or in Patients With Resolved Hepatitis C

End stage HCV-related cirrhosis has become a major indication for liver transplantation (LT). Unfortunately, recurrence of HCV infection on the liver graft occurs in almost all patients following transplantation and causes a persistent infection that leads to chronic hepatitis and cirrhosis in a significant proportion of patients. To date there ...

A Surveillance Program for the Detection of Hepatitis B Virus (HBV) Resistance to Tenofovir in HIV-HBV co-Infected Patients

Tenofovir disoproxil fumarate (TDF) is a nucleotide analogue that can inhibit both HIV and HBV DNA polymerases, and is active against wild-type HBV and HBV strains that contain lamivudine-associated polymerase gene mutations (Dore, Cooper et al. 2004). TDF was approved for use, in combination with other antiretrovirals, for HIV therapy ...

Phase N/A

Innate Immunity in HIV Positive Patients Co-infected With Hepatitis C Virus (HCV) or Hepatitis B Virus (HBV)

It has been demonstrated that Toll-like receptors (TLR) are involved in viral hepatitis - hepatitis B (HBV), hepatitis C (HCV) - and HIV in the setting of mono-infection. However the role of innate immunity in the pathogenesis of HIV-hepatitis co-infection in both natural and therapy-associated viral clearance remains unclear. The ...

Seroprevalence of Hepatitis B Infection and Effect of Booster Response Amongst Taiwanese Young Adults

Hepatitis-B virus infection is endemic in Taiwan with 90% of the adult population having been previously infected with HBV at some stage in their lives, and with approximately 15 - 20% of the general population being carriers of HBV surface antigen at time of writing. In 1984, Taiwan implemented a ...

Phase N/A

The Risk of Exacerbation of Chronic Hepatitis B After Percutaneous Radiofrequency Ablation of Hepatocellular Carcinoma

It has been reported that HBV replication can be reacted after chemotherapy or immunotherapy, which will lead to exacerbation of chronic hepatitis B (ECHB). It is still unknown that if percutaneous radiofrequency ablation or liver resection for hepatocellular carcinoma (HCC) will react the replication of HBV or not. This study ...

Phase N/A

Sonazoid Enhanced Liver Cancer Trial for Early Detection

The aim of this study is to prove usefulness of contrast-enhanced ultrasound (CE-US) using Sonazoid (TM) in the early detection of HCC as compared with conventional B-mode ultrasound (B-mode US) for hepatitis virus related cirrhosis, who are defined as super high-risk patients for hepatocarcinogenesis,Furthermore, to analyze whether early detection of ...

Phase N/A

Antigen-specific Immune Response to Hepatitis B Virus in Utero

Despite the development of an effective preventive HBV vaccine, the spread of HBV virus continue, particularly in Asia, where the majority of HBV infection is acquired at birth by vertical transmission from mother to baby. HBV vertical transmission has been hypothesized to cause immune tolerance to HBV and thus promoting ...
