Successful Eradication of Hepatitis C Virus by Interferon-Free Regimens in Two Patients with Advanced Liver Fibrosis following Kidney Transplantation

Hepatitis C virus (HCV) infection leads to acute and chronic hepatitis, cirrhosis, and hepatocellular carcinoma. Following kidney transplantation, HCV increases the risk of graft loss and patient mortality compared with uninfected patients. The achievement of a sustained virological response with antiviral therapy improves survival and diminishes the risk of hepatic decompensation in HCV patients after a kidney transplant. It has been reported that direct-acting antivirals (DAAs) are relatively safe and highly effective for the eradication of HCV in patients who are liver transplant recipients. In the present study, we investigated HCV eradication via interferon-free therapies with DAAs in two HCV patients with advanced liver fibrosis following renal transplantation. In both cases, the interferon-free regimens with DAAs were effective in eradicating HCV in the patients after kidney transplantation. No adverse events caused by interferon were identified with the exception of anemia. Interferon-free regimens with DAAs for recurrent HCV in patients following kidney transplantation are relatively safe and effective. However, attention should be focused on anemia during these treatments.
