Background: According to recent estimates, the prevalence of Chronic Hepatitis C (CHC) in Canada is three times more common in First Nations (FN)and Metis compared to non-FN populations. Moreover, once infected, the progression of CHC to cirrhosis and/or hepatocellular carcinoma is greater in FN patients due to the increased prevalence of alcohol abuse, obesity and diabetes in this segment of the population. Research Plan: This research proposal consists of three parts. The objective of Part I is to document the response to anti-viral treatment for CHC among treatment-naïve FN and Metis and Caucasian (hereafter referred to as non-FN) patients residing in three urban Western Canadian centres (Winnipeg, Saskatoon and Regina). Demographic, clinical and response to treatment data in a total of 160 patients (80/group) will be collected at the above centres and transferred to the Section of Hepatology at the University of Manitoba for statistical analyses. In Part II, the applicants will document and compare the immune responses to HCV proteins throughout the course of therapy in FN, Metis and non-FN patients. In the final part, direct economic costs of CHC care in FN, Metis and non-FN patients will be ascertained and future costs predicted. Hypotheses: Part I - The rate of sustained virologic response (SVR) to treatment for CHC is higher in FN and Metis compared to non-FN and no Metis patients. Part II - The immune response to HCV proteins during anti-viral therapy for CHC is enhanced in FN and Metis compared to non-FN and non-Metis patients. Part III - The direct costs of health care utilization and delivery for CHC are similar among FN and Metis and non-FN and non- Metis patients.
Treatment of patients with chronic hepatitis C infected with genotype 1 hepatitis C virus (HCV) consists of combined peginterferon/ribavirin for 48 weeks. Approximately 50% of patients experience sustained virological response which equals cure. All other patients either do not respond or experience recurrence of HCV virus and chronic hepatitis. Important predictors of successful treatment are sustained dosing of both peginterferon and ribavirin. With regard to the latter, clinical evidence indicates that higher ribavirin doses may in fact even improve treatment outcome. However, high ribavirin doses cause hemolytic anemia which require dose reductions. Recent clinical experience show that erythropoetic growth factors, including erythropoetin, can counteract hemolytic anemia caused by antiviral treatment in chronic hepatitis C patients. Therefore, the current trial aims to test whether higher ribavirin doses adapted to a target plasma concentrations instead of a weight-based dosing result in better healing rates, and whether ribavirin-associated hemolytic anemia can be compensated by concommitant erythropoetin treatment. Using a randomized, controlled, open-label design, the investigators hypothesize that patients with high ribavirin doses adapted to plasma levels experience better viral clearance than patients treated with standard weight-based ribavirin doses. In addition, the investigators hypothesize that erythropoetin treatment will counteract hemolytic anemia induced by ribavirin thereby allowing maintenance of target plasma concentrations without ribavirin dose reductions.
The purpose of this study is to determine if rosiglitazone, a medicine used to treat diabetes, improves response to anti-viral treatment.
The purpose of this study is to investigate T-cell mediated immune responses to HIV-1 and HCV and determine how these responses are affected by HCV treatment and correlates to response. Furthermore, to study Interferon-inducible protein-10 (IP-10) dynamics during HCV treatment, and correlate this to treatment outcome.
There is a distinct lack of published literature on the effect of combination treatment of PEG-interferon and ribavirin on post-renal transplantation hepatitis C virus (HCV) patients. Small case series have been published utilizing conventional interferon and/or ribavirin and the available data is extremely preliminary in nature. A small retrospective series of patients treated with Pegylated interferon and ribavirin published recently suggests that the treatment may be safe and efficacious. Unpublished reports from a few centers within Saudi Arabia also suggest a good safety profile and reasonable efficacy from this form of combination treatment. The investigators aim to prospectively study the safety and efficacy of PEG-interferon and ribavirin combination therapy in post-renal transplant HCV-infected patients. Towards this 40 patients with histological evidence of liver disease will be recruited and the efficacy of the above medications studied. The proposed study aims to evaluate the efficacy and safety of PEG-interferon and ribavirin combination therapy in the treatment of chronic HCV in renal transplant patients in a way that will allow management of such patients in an optimized manner.
The purpose of this study is to compare several Debio 025 (alisporivir)/peg-IFNα2a/ribavirin triple therapies with the current standard of care (SOC) in treatment naïve chronic hepatitis C genotype 1 patients.
The purpose of this study was to assess the safety, tolerability, pharmacokinetics and antiviral activity of ABT-333 (also known as dasabuvir) in treatment-naïve, hepatitis C virus (HCV)-infected participants.
