title: Ifn/Rbv treatment induced anemia and its correction with epoetin alpha in patients with hepatitis C.
abstract: The aim of the 18 months follow up study was to assess the frequency of anemia during IFN/RBV therapy in patients with chronic hepatitis C; to manage anemia either with recombinant human erythropoietin (rHuEPO)--epoetin alpha or with RBV dose reduction and to compare the rate of SVR in patients with RBV dose reduction and with administration of epoetin alpha. Study enrolled 61 patients with chronic active hepatitis C aged 33-61 years. All patients had HCV genotype 1b. Out of them 41 were male and 20 female. Anemia (Hb <10 or >2 g/dL Hgb drop from baseline) developed in 41 patients out of 61 (67,21%) during the therapy. These 41 patients were randomized into two groups: 21 patients who received 40 000 IU epoetin alpha weekly (I group) and 20 patients in whom for managing anemia we used standard of care (SOC) or RBV dose reductions from 1000/1200 to 800/600 mg (II group). In all 21 patients of the I group the Hb level normalized without reduction of RBV dose. In this group of patients SVR at 6 months after completion of full course of treatment was achieved in 17 (66%) patients. Improvement of quality of life (QOL) was observed in all 21 patients. Out of 20 patients of II group with standard of care (SOC) 5 patients developed symptomatic anemia with fatigue and dyspnoea; RBV was stopped temporarily. In 15 patients RBV dose was reduced from 1200 mg to 600 mg for correction of anemia. In this group of patients SVR at 6 months after treatment completion was achieved in 7 (25%) patients. Lower RBV doses yield a lower treatment response in patients with HCV genotype 1. In anemic HCV-infected patients on RBV/PEG-IFN therapy, EPO maintains RBV dose and significantly improves anemia and QOL. EPO has the potential to improve adherence rate, which may in turn improve SVR.
