Reporting Groups
Hepatitis C Treated With Peginterferon and Ribavirin Patients infected with hepatitis C virus (HCV) treated with peginterferon alpha-2a and ribavirin. After screening evaluation, patients will receive a first course of 2 weeks of peginterferon alfa-2a (180 micrograms weekly) and ribavirin (1000-1200 mg daily) during which symptoms, routine laboratory tests, HCV RNA levels, natural killer (NK) cell activity, and lymphocyte interferon-signaling responses will be monitored. After a 4-week washout period, patients will start SAMe (800 mg twice daily) for 2 weeks and then begin a second course of peginterferon and ribavirin in the same doses with similar monitoring. Therapy will be continued for at least 12 weeks, and patients with an early viral response will continue for a full 48 weeks.
