Abstract

Abstract The aim of this study was to investigate the utility of baseline plasma interferon-gamma inducible protein-10 (IP-10) levels in human immunodeficiency virus (HIV)-hepatitis C virus (HCV) co-infected patients. Baseline IP-10 was monitored during HCV combination therapy in 21 HIV-HCV co-infected patients (HCV genotype 1 (n = 16), 2 (n = 2), and 3 (n = 3)). Lower baseline IP-10 was significantly associated with a rapid decline in HCV RNA, in particular with the first phase reduction, and similar cut-off levels (<150 and >600 pg/ml) as in HCV mono-infected patients apply. In conclusion, baseline IP-10 <150 pg/ml is predictive of a favourable viral response to HCV therapy in HIV-HCV co-infected patients, and may thus be useful in encouraging such difficult-to-treat patients to initiate therapy
