Blood Sample Study of viral and Immune Responses to Treatment in People with HIV or Hepatitis C Infections
Contact Information
VA Palo Alto Health Care System 3801 Miranda Avenue Palo Alto, CA 94304Brief
You are being invited to participate in this study because you have human immunodeficiency virus (HIV) infection or you have hepatitis C virus (HCV) infection or both HIV and HCV infection. 20 HIV infected men and/or women, 40 HIV/HCV co-infected men and/or women and 20 HCV infected men and/or women will participate in this study. If you have evidence of HIV and/or the HCV virus in your blood, we would like to examine your blood.. We are trying to determine if HCV treatment or HIV treatment makes the immune system respond differently. We will also try to detemine if the amount or type of HCV virus changes over time in people infected with only HCV virus compared to those who have both HIV and HCV infection. We will examine your blood samples to answer these questions.
