Full-dose sofosbuvir plus low-dose ribavirin for hepatitis C virus genotype 2-infected patients on hemodialysis

ABSTRACT

Background/Aims@#New direct-acting antivirals have shown surprising success in the treatment of hepatitis C, not only in the general population, but also in difficult-to-treat cohorts. However, there is still limited data regarding direct-acting antivirals, including sofosbuvir (SOF), in the context of hemodialysis. The aim of this study was to investigate the safety and outcome of administering full-dose SOF (400 mg/day) plus low-dose ribavirin (RBV, 100 to 200 mg/day) in hemodialysis patients with hepatitis C virus (HCV) genotype 2 (GT2) infection. @*Methods@#Patients with chronic HCV GT2 infection and end-stage renal disease on maintenance hemodialysis treated with full-dose SOF plus low-dose RBV were retrospectively identified from a database of patients with HCV GT2 who were treated in Konkuk University Chungju Hospital between February 2017 and February 2018. Medical records were reviewed for demographics, medical history, laboratory data, and radiologic and electrocardiographic findings. @*Results@#All nine patients completed a full course of 12 weeks of treatment with a full-dose SOF plus low-dose RBV regimen. Two had compensated cirrhosis. Seven patients were treatment-naïve, and two had a relapse following previous interferon-based therapy. All patients had a sustained viral response at 12 weeks post-treatment. There was no discontinuation of treatment because of side effects. @*Conclusions@#In hemodialysis patients with HCV GT2 infection, the full-dose SOF plus low-dose RBV regimen appears to be safe and well tolerated, and yields high rates of sustained virologic response.
