The treatment of chronic hepatitis C with peginterferon alfa-2a (40 kDa) plus ribavirin in haemodialysed patients awaiting renal transplant

Background/Aims We undertook a pilot study to investigate the efficacy and safety of peginterferon alfa-2a (40 kDa) plus ribavirin in haemodialysed chronic HCV patients awaiting renal transplant. Methods Patients received peginterferon alfa-2a 135 μg/week plus ribavirin 200 mg/day for 24 or 48 weeks (genotype non-1 and 1, respectively). The dose of ribavirin was tailored according to plasma concentrations and to haemoglobin levels. Outcomes in treated patients were compared with those of a matched untreated control group. Results Thirty-five patients received treatment, while 35 served as untreated controls. Thirty patients completed treatment; patients were withdrawn due to transplantation ( n = 2), severe anaemia ( n = 1), dermatitis ( n = 1) and non-response ( n = 1) resulting in a drop-out rate of 14%. Overall, 34/35 treated patients were HCV RNA negative at week 4 and had undetectable RNA at the end of treatment, compared with none of the untreated controls (ETR 97% vs 0%; p < 0.001). Moreover, all achieved sustained virological response after 24 weeks of treatment-free follow-up versus no control patients (SVR 97% vs 0 %; p < 0.001). Conclusions In this study, we have shown for the first time in a large cohort of patients that HCV-patients on haemodialysis can be treated successfully with peginterferon alfa-2a (40 kDa) plus ribavirin.
