RESUMEN
INTRODUCTION: Sofosbuvir is the first directly-acting antiviral for the treatment of hepatitis C virus. First, the regimens were combinations with sofosbuvir+ribavirin (SR) or with sofosbuvir+ribavirin and pegylated-interferon α-2a (SPR) with cure rates around 90%. The aim of this study was to report the results of these combinations in 'real-life' in France. MATERIALS AND METHODS: Main features of patients treated with SR or SPR in 24 hospitals were collected. Undetectable hepatitis C virus week 12 viral load after treatment defined sustained virological response (SVR12). Statistics were performed using StatView software for descriptive analysis and χ for the sub-groups comparisons. RESULTS: Two hundred and eleven patients were analyzed. The average age was 56.1. One hundred and seventy-one (89%) patients had a fibrosis score of at least 3. Seventy-nine patients were infected by a genotype 1 (G1). One hundred and thirteen patients were treated with SR and 95 with SPR. In naive patients: with SPR for 12 weeks, SVR12 was 93% in G1, 100% in G3 and 83% in G4. With SR for 12 weeks, SVR12 was 100% in G2 patients (6/6). The safety of these regimens was satisfactory with only two patients who had to stop P due to severe side effects. Multivariate analysis shows a higher SVR in SPR versus SR (odds ratio = 1.28; P = 0.05) and in G2 or G3 versus others (odds ratio = 1.56; P = 0.04). Moreover, Child-Pugh score B or C (P = 0.02), platelets count under 100G/l (P = 0.05) or a past event of ascites (P = 0.04) was independently associated with less SVR. CONCLUSION: This multicenter large study confirms the good results of SR for 12 weeks in G2 naive patients. Finally, a decompensated cirrhosis, a past event of ascites and a baseline low platelet count were strongly associated with poor response.
