Abstract
Background
While the necessity of treatment of HCV patients with advanced liver disease is widely accepted, the benefit of treating HCV patients without significant liver disease is less well established. Our aim was to assess the effect of treating HCV in patients with no or minimal fibrosis (F0-F1) on patients-reported outcomes (PROs). Methods
HCV patients with F0-F1 from 16 clinical trials were included. PROs were collected before, during, and after treatment using SF-36V2, FACIT-F, CLDQ-HCV, and WPAI:SHP. Results
1,548 HCV patients with F0-F1 were included (age 46±11 years, 43% male, 82% Caucasian, 64% employed, 81% treatment-naïve, 57% genotype 1). Patients were treated with interferon+sofosbuvir+ribavirin (N=91) or sofosbuvir+ribavirin±ledipasvir (N=479) or interferon- and ribavirin-free regimens with sofosbuvir+ledipasvir or sofosbuvir+velpatasvir or sofosbuvir+velpatasvir+voxilaprevir (N=978). There were no PRO differences at baseline (all p>0.01). By the end of treatment, F0-F1 patients receiving interferon-containing regimens experienced significant decreases in most PRO domains (-4.5 to -28.7 on a 0-100 scale), while subjects treated with interferon-free ribavirin-containing regimens had a modest impairment of PROs (-2.3 to -8.9) (p≤0.01). In contrast, treatment with regimens without interferon and ribavirin led to PRO improvements (+1.2 to +10.9). Regardless of the regimen, SVR-12 and -24 were universally associated with PRO improvements (+2.1 to +14.7, all p<0.0001). In multivariate analysis, receiving interferon-containing (β=-5.3 to -28.5, p<0.01) or interferon-free ribavirin-containing (β=-2.8 to -10.6, p<0.01) regimens were predictive of PRO impairments during and after treatment. Conclusions
HCV subjects with none or minimal fibrosis treated with interferon- and ribavirin-free regimens experience on-treatment and post-SVR PRO improvements.
