Racial Difference in HCV/Host Interactions

The purpose of this study is to evaluate a group of African Americans and Caucasians with hepatitis C virus (HCV), compare their response rates to combination treatment with pegylated interferon alfa-2b and ribavirin, and identify possible causes for racial differences in response to therapy. The study will enroll a total of 260 participants, age 18 or older, over a 10 period. In the next 5 years 132 subjects will be studied locally, including 112 African Americans and 20 Caucasians. Participants will be recruited from the clinical practices of the hepatologists (liver doctors) at the University of Tennessee Health Science Center and will also be selected from referrals at local hepatology clinics and the Memphis VA Hospital. Volunteers will be treated with pegylated interferon alfa-2b injections once weekly and oral ribavirin 2 times a day for up to 72 weeks. Study procedures include multiple blood draws. Participants may be involved in study related procedures for up to 72 weeks.
