Objectives: Historically, hepatitis C virus genotype 3 infection has not been as hard to treat as genotype 1 using interferon-based therapy. Now, genotype 3 infection can be treated using interferon-free regimes such as the combination of sofosbuvir and daclatasvir, which is a highly successful and reliable therapeutic option before liver transplant. However, real world data are rather limited regarding the use of antivirals (sofosbuvir/daclatasvir) for hepatitis C virus genotype 3 recurrence after liver transplant. Here, we present the results of antiviral treatment with sofosbuvir and daclatasvir in patients with genotype 3 recurrence after liver transplant and also viewed published data, to finally close the chapter on genotype 3 elimination.
Materials and methods: We analyzed 11 patients who received liver transplants due to hepatitis C virus genotype 3-associated cirrhosis at our center. Two patients were nadve for any antiviral therapy. All patients received antiviral treatment with sofosbuvir/daclatasvir for 12 weeks after liver transplant, with 1 patient also having ribavirin. The endpoint was hepatitis C virus RNA-free survival after 12 weeks of therapy. Secondary endpoints were preservation of renal and liver function and incidence of adverse events.
Results: All patients were free of hepatitis C virus RNA by at least 8 weeks after therapy initiation. Elevated transaminases and gamma-glutamyltransferase at the beginning of therapy normalized quickly during treatment. Synthesis and excretion were stable at all dates. Patients displayed no severe adverse effects, especially regarding renal function and blood counts. Sustained virologic response rates at week 12 were achieved in all 11 patients.
Conclusions: Hepatitis C virus could be eliminated in all patients after liver transplant with 12-week sofosbuvir/daclatasvir therapy. Sofosbuvir combined with daclatasvir is safe and reliable for recurrent hepatitis C virus genotype 3 infection. Our results have closed the chapter on genotype 3 recurrence after liver transplant in our outpatient clinic.
