Aims:
- Efficacy 1.1) Rate of RNA-HCV negative at week 4 and 24 in each arm. 1.2) Rate of SVR in each arm.
- Safety 2.1) Rate of adverse effects in each arm.
Design: Randomized controlled trial.
Patients will be randomly allocated into three arms:
Arm A : Peginterferon α-2a (180 μg/week)SC. plus Ribavirin (800 mg/day) p.o. over 24 weeks.
Arm B: Peginterferon α-2a (180 μg/week) plus Ribavirin (1600 mg/day) with support of Epoetin β (450 IU/kg/week) SC over 4 weeks:
B1.- If RNA-HCV undetectable at week 4, standard of care will be continued (Peginterferon α-2a, 180 μg/wee plus Ribavirin (800 mg/day) over 20 additional weeks).
B2.- If RNA-HCV were detectable at week 4, treatment will be continued with peginterferon α-2a (180 μg/week) plus RBV(1,600 mg/day) plus Epoetin β (450 UI/kg/week) over 20 additional weeks.
Sample size: 111 patients. To increase the SVR from 50% to 75%. Beta: 0.1; alfa: 0.05; Loss: 15%.
Randomization will be 1:2, 37 patients in Group A and 74 patients in group B.

实验性的:B1
After a period of 4 weeks with peginterferon alfa 2 a 180 mcg/week plus RBV 1600 mg/day (Induction phase), these patients will be allocated according to negativity or positivity of RNA-HCV at week 4.
If RNA-HCV negative, treatment with peginterferon alfa 2 a 180 mcg/week plus RBV 800 mg/day (SOC) will be continued over 20 additional weeks (Arm B1).
Epo β (450 IU/kg/week) will be administered as required to maintain hemoglobin > 12g/dL.
