Effect of ribavirin and amantadine on early hepatitis C virus RNA rebound and clearance in serum during daily high-dose interferon.

Abstract:

:The early rebound in serum HCV RNA during HCV dynamic studies with high-dose interferon may be due to de novo infection with interferon escape quasispecies. We simultaneously measured serum alanine aminotransferase (ALT) and HCV RNA at rapid intervals in chronic HCV liver disease patients during interferon therapy alone or in combination with ribavirin and amantadine. HCV RNA declined rapidly between 0 and 48 hr in all patients (phase 1). Ribavirin and amantadine significantly increased this phase 1 decline. In all four monotherapy patients with viral rebound, the increasing levels of HCV RNA were associated with a parallel increase in serum ALT, consistent with a hepatitis flare or de novo infection. By contrast, in the four monotherapy patients without viral rebound, and all eight patients receiving combination therapy, the slow progressive phase two decay was associated with declining serum ALT levels. Ribavirin or ribavirin and amantadine significantly and incrementally increased the phase two HCV RNA clearance. Dynamic sequencing in the HVR1 region in one rebound patient confirmed the potential for rapid evolutionary changes during interferon therapy. These preliminary data suggest that early viral rebound might be associated with de novo infection with interferon escape HCV variants, which in turn are attenuated by ribavirin and amantadine.
