AIM: Treatment of hepatitis C virus (HCV) infection in patients with end-stage renal disease (ESRD) is difficult. Addition of ribavirin to pegylated-interferon (Peg-IFN) may help to improve the treatment response. Further, treatment duration could be shortened using a response-guided treatment (RGT) approach. METHODS: We retrospectively reviewed records of treatment-naïve adult patients with ESRD and chronic HCV infection who had been treated with Peg-IFN and low-dose ribavirin using a RGT approach. Rapid responders (undetectable HCV-RNA at 4 weeks) received treatment for 12 weeks, and slow responders (HCV-RNA detectable at 4 weeks, but undetectable or with >2.0 log10 reduction at week 12) for 24 (genotype 3; GT3) or 48 (genotype 1; GT1) weeks. In those without such reduction (null responders), treatment was discontinued. RESULTS: Of 26 non-cirrhotic patients (GT1 15, GT3 11) treated, four (15%; GT1 3, GT3 1) were null responders. Twenty-two (85%) patients had either rapid (n = 14 (54%); GT1 10, GT3 4) or slow response (n = 8 (31%); GT1 2, GT3 6). Of them, 21 patients had undetectable RNA at the end of treatment; one could not complete the treatment and was lost thereafter. There were no deaths during treatment. Three patients relapsed and three others died in 6 months after stopping treatment. Overall, 15/26 (58%) patients attained SVR24. Fourteen patients underwent transplantation beginning one month after treatment completion, and all were relapse-free after 17 (14-24) months of follow-up. CONCLUSION: RGT using Peg-IFN and ribavirin was effective in ESRD patients on maintenance dialysis. Renal transplant was safely done within one month of completing such treatment.
