HCV targeting of patients with cirrhosis.

Interferon (IFN)-free treatments are now the treatment of choice for patients with chronic hepatitis C. Previously difficult to treat patients by IFN-containing treatments can now be treated safely by IFN-free therapies. More than 90% of hepatitis C genotype 1 and 4 patients with compensated cirrhosis or after orthotopic liver transplantation (OLT) can be cured by sofosbuvir combined with simeprevir, daclatasvir or ledipasvir, or by the paritaprevir/ritona-vir/ombitasvir/±dasabuvir (3D) combination. Addition of ribavirin confers to a minimal, if any, benefit to increase SVR. The need for ribavirin is controversial and remains to be studied. The optimal length of treatment is still unknown, and an individual approach may be needed. Most patients require only 12weeks of therapy. The safety of these drugs is not fully explored in patients with decompensated cirrhosis (Child-Pugh C), who should not be treated with protease inhibitors. In cirrhosis hepatitis C virus eradication does not necessarily mean a cure of the disease and patients regularly require follow-up. Drug-drug interactions with immunosuppressant in patients after OLT are easier to manage but still require attention. Better drugs are needed for genotype 3 patients.
