Pre-treatment plasma level of IP-10 (cutoff: 600 pg/mL) could predict whether standard-of-care (interferon plus telaprevir) for hepatitis C would achieve a rapid viral response or sustained viral response [10]; the median serum IP-10 level in patients with spontaneous clearance of HCV was lower than that in patients without spontaneous clearance [11]. Here, CXCL10 is linked to hepatitis C virus infection.
