Abstract

Indoleamine 2,3-dioxygenase (IDO) activity as determined by increases in serum kynurenine was measured in a group of hepatitis C patients treated with consensus interferon (IFN-con1). Kynurenine levels increased significantly within 2 days of initiation of treatment but returned to normal values by week 4 after treatment. Although IDO is normally induced by IFN-γ, no such IFN was detected by ELISA or biologic assays. Thus, consensus IFN induces low levels of IDO in vivo without an IFN-γ intermediate.
