ABSTRACT
OBJECTIVE:
Data comparing the efficacy and safety of combination therapy with peginterferon plus low-dose ribavirin and peginterferon monotherapy in treatment-naive haemodialysis patients with hepatitis C virus genotype 2 (HCV-2) infection are limited.DESIGN:
In this randomised trial, 172 patients received 24â weeks of peginterferon alfa-2a 135â µg/week plus ribavirin 200â mg/day (n=86) or peginterferon alfa-2a 135â µg/week (n=86). The efficacy and safety endpoints were sustained virological response (SVR) rate and adverse event (AE)-related withdrawal rate.RESULTS:
Compared with monotherapy, combination therapy had a greater SVR rate (74% vs 44%, relative risk (RR) 1.68 [95% CI 1.29 to 2.20]; p<0.001). The beneficial effect of combination therapy was more pronounced in patients with baseline viral load ≥800,000 IU/mL than those with baseline viral load <800,000â IU/mL (RR 3.08 [95% CI 1.80 to 5.29] vs. RR 1.11 [95% CI 0.83 to 1.45]; interaction p=0.001). Patients receiving combination therapy were more likely to have a haemoglobin level of <8.5â g/dL (70% vs. 8%, risk difference (RD) 62% [95% CI 50% to 73%]; p<0.001) and required a higher dosage [mean 13,417 vs. 6667 IU/week, p=0.027] of epoetin ß to manage anaemia than those receiving monotherapy. The AE-related withdrawal rates were 6% and 3% in combination therapy and monotherapy groups, respectively (RD 2% [95% CI -4% to 9%]).CONCLUSIONS:
In treatment-naive haemodialysis patients with HCV-2 infection, combination therapy with peginterferon plus low-dose ribavirin achieved a greater SVR rate than peginterferon monotherapy. Most haemodialysis patients can tolerate combination therapy. TRIAL REGISTRATION NUMBER ClinicalTrial.gov number, NCT00491244.Palavras-chave
