N2 - Background & Aims Interferon treatment for chronic hepatitis C is associated with non-specific symptoms including fever. We aimed to determine the association of temperature changes with interferon antiviral activity. Methods 60 treatment-naïve patients with chronic hepatitis C (67% genotype 1/4/6, 33% genotype 2/3) were admitted to start peginterferon alfa-2a and ribavirin in a clinical trial. Temperature was measured at baseline and 3 times daily for the first 24 h and the maximal increase from baseline during that time (ΔTmax) was determined. Serum HCV-RNA, interferon-gamma- inducible protein-10 (IP-10) and expression of interferon-stimulated genes (ISGs - CD274, ISG15, RSAD2, IRF7, CXCL10) in peripheral blood mononuclear cells (PBMCs) were measured at very early time points, and response kinetics calculated. The IL28B single nucleotide polymorphism, rs12979860, was genotyped. Results Temperatures rose by 1.2 ± 0.8 C, peaking after 12.5 h. ΔTmax was strongly associated with 1st phase virological decline (r = 0.59, p max (1.4 ± 0.8 C vs. 0.8 ± 0.6 C, p = 0.001). ΔTmax was associated with 6- and 24-h induction of serum IP-10 and of PBMC ISG expression, but only in patients with rs12989760CC. ΔTmax weakly predicted early virological response (AUC = 0.68, CI 0.49-0.88). Conclusions Temperature rise following peginterferon injection is closely associated with virological response and is modulated by IL28B polymorphism, reflecting host interferon-responsiveness.
