Adrian M. Di Bisceglie, Jay H. Hoofnagle – 10 February 2006 – The highest response rates to antiviral therapy for the treatment of chronic hepatitis C have been achieved using the combination of peginterferon and ribavirin. Recently completed controlled trials have reported rates of sustained virological response (SVR) between 50% and 60% in patients treated with higher doses of peginterferon and ribavirin, which was 5% to 1O% higher with standard doses of interferon alfa and ribavirin. The major determinant of outcome of therapy is hepatitis C virus (HCV) genotype.
Hashem B. El‐Serag – 10 February 2006 – Chronic infection with hepatitis C virus (HCV) is a major risk factor for development of hepatocellular carcinoma (HCC). In general, HCC develops only after 2 or more decades of HCV infection and the increased risk is restricted largely to patients with cirrhosis or advanced fibrosis. Factors that predispose to HCC among HCV‐infected persons include male sex, older age, hepatitis B virus (HBV) coinfection, heavy alcohol intake, and possibly diabetes and a transfusion‐related source of HCV infection. Viral factors play a minor role.

Marion G. Peters, Norah A. Terrault – 10 February 2006 – Excess alcohol consumption can worsen the course and outcome of chronic hepatitis C. It is important to distinguish between alcohol abuse, which must be treated on its own merits, and the effect of alcohol use on progression, severity, and treatment of hepatitis C. Most studies on the effects of alcohol on hepatitis C have focused on patients with high levels of daily alcohol intake.
Brian R. Edlin – 10 February 2006 – Injection drug users constitute the largest group of persons infected with the hepatitis C virus (HCV) in the United States, and most new infections occur in drug users. Controlling hepatitis C in the U.S. population, therefore, will require developing, testing, and implementing effective prevention and treatment strategies for persons who inject drugs. Fortunately, a substantial body of research and clinical experience exists on the prevention and management of chronic viral diseases among injection drug users.
Mitchell L. Shiffman – 10 February 2006 – Significant advances have been made in the treatment of chronic hepatitis C virus (HCV) infection during the past 5 years. As a consequence, there is continuing enthusiasm for retreating patients who did not achieve sustained virological response (SVR) with previous therapy. Retreatment of non‐responders to standard interferon monotherapy using interferon and ribavirin has yielded SVR rates of 12% to 15%. Retreatment with peginterferon and ribavirin has been more effective; achieving SVR rates of 34% to 40%.
Robert J. Fontana, Anna S. F. Lok – 10 February 2006 – Hepatic fibrosis is the main determinant of clinical outcomes of chronic hepatitis C. Liver histology is frequently considered the gold standard for assessing hepatic fibrosis. However, liver biopsy is associated with sampling error, interobserver variability, and potential complications. Thus, there is a need for simple, inexpensive, and reliable noninvasive means to assess disease severity in patients with chronic hepatitis C. Clinical examination is unreliable in differentiating different stages of compensated liver disease.
