Filter by:The purpose of this study is to determine if orlistat (Xenical) therapy in overweight patients with NASH leads to enhanced weight loss over time, with subsequent improvement in the underlying necroinflammatory and fibrotic changes that are typical of NASH.
The primary objective of this study is to determine the safe and effective dose range of boceprevir (SCH 503034) in combination with PEG-Intron in adult subjects who have chronic hepatitis C without cirrhosis, and who have failed an adequate course of combination therapy with peginterferon-alfa plus ribavirin. A secondary objective is to explore whether ribavirin provides an additional benefit when combined with PEG-Intron plus boceprevir.
To compare the two formulations of GSK Biologicals' DTPw-HBV vaccine to concomitant administration of CSL's DTPw vaccine and GSK Biologicals' HBV with respect to the antibody response to the diphtheria antigen after a three-dose primary vaccination course.
To investigate the durability of HBeAg seroconversion in patients with chronic hepatitis B virus infection (HBV) who have seroconverted while participating in a previous Gilead-sponsored study of adefovir dipivoxil.
Acute hepatitis C is a liver disease related to a virus: hepatitis C virus (HCV). The type of Hepatitis C Virus present in Egypt (genotype 4), has the reputation to respond poorly to treatment at the chronic hepatitis stage. Without treatment, 85% of patients with acute hepatitis C become chronically HCV infected which means that the virus stays present in the body. Pegylated Interferon is a new form of Interferon that stays in the body for longer time and allows the patient to take less injection per week. It has also proved to be more effective than standard Interferon in treatment of chronic hepatitis C.
Chronic hepatitis C is a liver disease related to a virus: hepatitis C virus (HCV). The type of HCV present in Egypt (genotype 4), has the reputation to respond poorly to Interferon treatment at the chronic stage. Pegylated Interferon is a new form of Interferon that stays in the body for longer time and allows the patient to take less injection per week. It has proved to be more effective than standard Interferon. The combination of two drugs, Interferon and Ribavirin, is considered to be the best treatment available for chronic hepatitis C.
The objective of the study is to evaluate the safety and efficacy of celgosivir for 12 weeks in patients with chronic hepatitis C genotype 1 infection.
Taiwan is a hyperendemic area of hepatitis B virus (HBV) infection. Previous studies demonstrated vigorous T cell responses to HBV-encoded antigens developed in patients with self-limited acute hepatitis B. In contrast, weak or no T cell responses could be detected in chronic hepatitis B (CH-B) patients. However, these immune responses are still not well known in patients with acute exacerbation (AE) of CH-B and in patients with advanced liver diseases, such as liver cirrhosis (LC) and hepatocellular carcinoma (HCC). The CD4+CD25+ regulatory T cells might suppress immune responses against foreign antigens and pathogens. The roles of CD4+CD25+ regulatory T cells in patients chronically infected with HBV remain to be clarified. The high percentage of HBV carriers in Taiwan are related to the vertical transmissions. High maternal HBV viral load may make the newborns tolerant to the HBV. However, the HBV-specific CD8+ T cells responses in the cord bloods of newborns are still unknown. Thus, we want to resolve these issues in this study. We will enroll the HBsAg (+) patients from NTUH. Blood samples will be collected. We will then analyze the HBV-specific CD8+ T cell responses and the clarify the roles of regulatory T cells.
In France, 50% of the hepatitis C virus carriers develop chronic clinical hepatitis, which may lead to cirrhosis and liver transplantation. Transplant infection by hepatitis C virus is constant after transplantation. This recurrence usually causes chronic liver disease, in 50 to 80% of the patients. The interest of a long-term treatment with ribavirin alone after transplantation has not been clearly demonstrated. The objective of our study is to evaluate the efficacy of ribavirin as a maintenance treatment after a one year interferon-α / ribavirin therapy on hepatitis C recurrence in the transplanted liver.
Hepatitis C and HIV infect worldwide millions of people leading to a high rate of coinfected patient with eventually liver cirrhosis and endstage liver disease. With the currently best available therapy (peginterferon and ribavirin) only less than 50% of patients with HCV genotype 1 will respond. Unknown is what factors determine this difference in treatment outcome. Probably virologic and immunologic factors play a major role. By investigating blood samples of HCV / HIV coinfected patients and HCV mono-infected patients we would like to examine both virologic and immunologic factors possibly responsible for this difference.
