Filter by:The aims of this three-year study are to explore symptom experience and its related factors for the patients with chronic hepatitis C Infection receiving interferon-α with ribavirin for 24 weeks and further to predict the relative risk of failure or occurence of severe side effects which interrupt the treatment.
The purpose of this study is to reduce the HIV/HCV incidence among the clients attending community-based methadone maintenance treatment (MMT) , and to prevent the secondary sexual transmission from HIV+ clients to their spouse and sex partners, through intensified comprehensive intervention.
The purpose of this study is to compare how safe, tolerable, and effective a novel drug, raltegravir, is to a commonly used combination, atazanavir/ritonavir, as initial treatment in HIV/Hepatitis C co-infected injecting drug users on a methadone program.
This study aim to evaluate the non-inferiority of sustained virologic response in peginterferon alfa-2a and weight-based ribavirin for 16 weeks compare with standard treatment duration of 24 weeks in patients who achieved rapid virologic response with genotype 2 CHC.
Combination therapy with peginterferon plus ribavirin has become the current standard of care for chronic hepatitis C (CHC) patients, with an overall sustained virologic response (SVR) rate of 54-63%. Based on the ample evidence, a 48-week course of peginterferon plus weight-based ribavirin therapy is widely recommended to treat HCV genotype 1 infection in different parts of the world. Despite the increased SVR rates with the improved medical therapies, about 25-50% and 10-20% of HCV genotype 1 and HCV genotype 2/3 patients may experience relapse after the cessation of therapy with undetectable HCV viremia at the end of treatment. Moreover, combination therapy is costly and may cause various adverse events. Therefore, individualized therapy based on outcome analysis should be adopted to save medical cost as well as to lessen inadequate treatment. Few studies are aimed to evaluate the host responses of micro RNA regulation during interferon-based therapy and its relationships to the overall treatment responses. Micro RNA (miRNA) is a single-stand RNA composed of 21-23 nucleotides, which may regulate the function of messenger RNA (mRNA). The regulating mechanisms involving micro RNA between the hosts and the HCV virus include (1) auto-regulation of HCV mRNA by HCV miRNA; (2) regulation of host mRNA by HCV miRNA; and (3) regulation of HCV mRNA by host miRNA. MiR-122 is the abundant liver-specific miRNA which is crucial for efficient HCV replication in culture Huh7 cells stably expressing HCV replicons. Recently, an in vivo study for hepatic miR-122 of 42 patients with CHC who received IFN-based therapy showed that patients who did not respond to IFN therapy had markedly decreased pretreatment miR-122 levels. Although miR-122 is abundant in the liver, liver biopsy is still considered an invasive procedure, which prevents its widespread use in routine clinical practice. The miRNA can be detected in the sera and is stable after 24 hours of room temperature store or repeated freezing and de-freezing. The serum miR-122 levels can reflect the severity of liver injuries in a rat acetaminophen toxicity model. Because miR-122 is liver specific and the miRNA is stable in the sera, the investigators aimed to evaluate the role of serum and hepatic miR-122 on the viral kinetics and the treatment responses and in HCV patients receiving peginterferon and ribavirin combination therapy.
The purpose of this study is to analyze the efficacy and safety of a combination therapy of pegylated interferon (PEG-IFN) alpha-2b plus ribavirin (RBV) for older Japanese patients (≧65years old) infected with hepatitis C virus (HCV) compared with younger patients(< 65 years old).
INDICATION: Patients with chronic hepatitis C, genotype 1 and non-responders to standard treatment for hepatitis C. OBJECTIVES: 1. ascertain the rate of sustained response in patients with hepatitis C, genotype 1 with peginterferon + ribavirin resistance. 2. To know the response rate in 12 weeks 3. Describe the tolerance and safety of thalidomide in combination with peginterferon and ribavirin. DESIGN OF TEST Pilot Study: The single arm study will: 1. Thalidomide 200 mg and peg-interferon alfa 2b (based on weight: 50-120 mcg / week) + ribavirin (based on weight: 1000-1200mg / day) Be tracked for 24 weeks after treatment. Suspended treatment of 12 weeks in patients who have failed a drop of HCV RNA> 2 log. Patients who have been suspended for any reason, the treatment will be followed during 24 weeks, to assess safety parameters. SUBJECT NUMBER: 10
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 HCC by CE-US has a survival benefit than that by B-mode US.
We hypothesize that patients with Ch.HCV have a low level of vitamin D, and that by raising their vitamin D levels by adding it to their standard treament of Pegylated Interferon and Ribavirin, there will be an increase in their sustained virological response.
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 is no effective way to prevent HCV reinfection of the liver graft in the early phase after transplantation. . Early passive immunotherapy with neutralizing antibodies against HCV should be considered for preventing reinfection of liver transplanted patients associated with HCV. This approach is well established in the case of patients undergoing liver transplantation for chronic hepatitis B virus infection. Our purpose is to produce neutralizing monoclonal antibodies to prevent reinfection of the liver graft.
