Conclusion

It is now possible to cure HCV in the vast majority of patients with chronic HCV. SVR rates of 80–90% can be routinely achieved in patients with all HCV genotypes in as little as 12–24 weeks. Of the antiviral agents currently available, sofosbuvir appears to be the easiest to manage, the most efficacious and the antiviral agent with the broadest of indications. Patients with HCV genotypes 1, 4, 5 and 6 can be treated with sofosbuvir, PEGINF and RBV for 12 weeks. SVR rates of 90% or better are achieved. Patients with genotype 1 who are unable to tolerate PEGINF and patients with HCV genotype 3 can be treated with sofosbuvir and RBV for 24 weeks. SVR rates in these patients range from 75 to 83%. Patients with genotype 2 can be treated with sofosbuvir and RBV for 12 weeks with an SVR exceeding 90%. Simeprevir offers an SVR of about 80%, but requires 24 weeks of PEGINF and RBV. Patients with HCV genotype 1A and the Q80K mutation have SVR rates that are significantly reduced. Perhaps the best use for simeprevir is with sofosbuvir for 12 weeks in patients with HCV genotype 1. Our ability to eradicate HCV is on the horizon. However, this cannot be achieved unless patients are recognized and this will require screening in those persons at greatest risk, which is now defined by the year of their birth.
