Filter by:The purpose of this study is to investigate the mechanism of a successful immune response to hepatitis C virus (HCV) infection. Currently, it is believed that the immune system is involved in responding to HCV infection, but how it is involved is not known. It is estimated that 30% of individuals infected with HCV are able to clear the virus without treatment, while 70% progress to chronic infectious. By studying the immune responses in these two populations, we, the researchers at Rockefeller University, hope to gain insight into the mechanisms of the immune response and develop new strategies for HCV therapy.
This purpose of this study is to determine the safety and effectiveness of viramidine to ribavirin in chronic hepatitis C patients who have never before recieved treatment.
The purpose of this study is to assess the safety and efficacy of repeated intravenous infusions of EMZ702 in combination with pegylated interferon and ribavirin in patients with chronic hepatitis C genotype 1.
The purpose of this study was to explore whether a brief (3 session) intervention would impact health behavior of veterans with hepatitis C. The main focus of the intervention was on reduction of heavy drinking with patients who have liver disease. Other study goals were to increase the likelihood that patients would seek out substance use treatment and/or hepatitis C health care services. The study also tested the use of a liver function test called CDT/GGT in detecting heavy drinking. The main hypothesis was that a 3 session intervention with personalized feedback about health behavior would result in a reduction in alcohol use and increased use of substance use treatment and hepatology health care.
This study was conducted to determine the safety, tolerance, pharmacokinetics and antiviral activity of val-mCyd at doses ranging from 50 mg to 800 mg per day.
This is a long-term evaluation follow-up study of neurocognitive performance and emotional state in patients with chronic hepatitis C infection and a former (peg)interferon alfa-2b-based therapy. M.R. Kraus, G. Teuber, NN, NN (MPsych), M. Scheurlen Questions: - Neurocognitive and psychiatric changes induced by interferon alfa-2b therapy in patients with chronic hepatitis C - are they fully reversible in long-term follow-up after the end of antiviral treatment? - At least 12 months after the end of antiviral treatment - are neurocognitive and mood-related parameters even significantly improved as compared to pretreatment values? Is this possibly only true of patients with successful virus eradication? - At least 12 months after the end of antiviral treatment, is there a significant difference between patients with and without sustained virological response with respect to neurocognitive performance, emotional state and quality of life? - In the absence of clinically significant liver damage in patients with chronic hepatitis C - does the mere presence of the hepatitis C virus have any significant influence on neurocognitive or attentional performance? - Does the study data support an additional indication for antiviral therapy in chronic hepatitis C? In the case of successful virus eradication, emotional state and - above all - is neurocognitive performance significantly improved even in the absence of severe liver damage?
Combination of PEG interferon and ribavirin is the standard treatment of chronic hepatitis C. Efficacy of this treatment has never been evaluated in HCV-HIV infected patients, who have previously been treated with a first line anti-HCV treatment. The purpose of the study is to evaluate the combination PEG interferon alfa2a-ribavirin in HIV-infected patients with chronic hepatitis C pretreated with interferon alone or interferon combined with ribavirin. The patients receive a dose of 180 µg of PEGASYS once a week and 800 to 1200 mg/day of ribavirin (according to weight) for 48 weeks. Primary outcome of the study is a sustained virological response, defined as an undetectable HCV RNA level 24 weeks after the end of anti-HCV treatment.
Response to a second-line anti-HCV treatment in non responder patients to a first-line dual therapy remains very poor. Preliminary studies of amantadine suggest that this drug could be potentially effective to treat hepatitis C.
The purpose of this study is to measure specific chemokines, antibodies, and antibody-producing B cells in the blood of patients with hepatitis C virus (HCV) infection. Our hypothesis is that changes in chemokine levels affect the development of an effective immune response against HCV.
The purpose of this study is develop and test a cognitive-behavioral intervention to prevent depression in methadone maintenance patients receiving medical treatment for hepatitis C.
