NCT00241917
The investigators hypothesize that a well-designed hepatitis C (HCV)video education curriculum for high-risk drug users will show measurable benefits in improving HCV testing, hepatitis A and B vaccinations, and HCV knowledge, attitudes, and motivations toward transmission behavior change. The investigators will use a 4-part modular video series designed for at-risk drug users, and in this 12 week study will assess its impact on testing/vaccinations as well as knowledge, attitudes, and motivations in methadone-maintained drug users as compared to a usual-care intervention.
NCT00543244
Hepatitis C virus (HCV) infection is a global health problem, which may lead to chronic hepatitis, cirrhosis, hepatic decompensation and hepatocellular carcinoma (HCC). Recently, treatment with peginterferon alfa plus ribavirin has become the standard of care for patients with chronic hepatitis C. While genotype 2 patients can have higher sustained virologic response (SVR) rates to 80-90%, genotype 1 patients generally have low SVR rates of only 40-50%. In contrast, genotype 1 Taiwanese patients have superior SVR rates than those in Western countries. Despite the overall improved response to this combination therapy, more than 75% of patients suffer from treatment-related adverse events and the costs remain high, which make individualized therapy of paramount importance to maximize treatment response and minimize adverse events. HCV viral kinetics with interferon-based therapies have been studied recently to evaluate patient responses. Early viral kinetics shown to have favorable SVR rates, which make shorter treatment duration possible. However, different viral kinetics were found through ethnicity. Recently, a pilot study to evaluate the viral kinetics of 6 Taiwanese patients with HCV infection who received peginterferon alfa plus ribavirin therapy has shown superior early viral kinetics to those in Caucasian patients. Based on the favorable SVR rates in treating Taiwanese patients with chronic hepatitis C, the investigators aimed to conduct a large confirmatory study to evaluate the viral kinetics and try to define the optimal treatment for these patients.
