Cellular immune responses during high-dose interferon-alpha induction therapy for hepatitis C virus infection.
BACKGROUND: The effect that high-dose interferon (IFN)-alpha induction therapy for hepatitis C virus (HCV) infection has on cellular immune responses is currently unknown. METHODS: Thirty-one treatment-naive patients with chronic HCV infection received amantadine and ribavirin, combined with 6 weeks of high-dose IFN-alpha-2b induction therapy followed by weekly pegylated IFN-alpha-2b, for 24 or 48 weeks. Using IFN-gamma and interleukin (IL)-2 enzyme-linked immunospot (ELISpot) assays, we anal...Expand abstract
