Background and aim: Direct Acting Antivirals(DAAs) achieve the highest rate of sustained viral response(SVR) in patients with genotype-1b(G1b) Hepatitis C virus(HCV) infection. Reducing treatment duration can simplify the management and improve adherence of therapy. Patients and methods: The study evaluates the efficacy of 8 weeks of elbasvir/grazoprevir regimen in 75 treatment-naïve(TN), G1b patients with mild-moderate fibrosis(Liver Stiffness by Fibroscan® <9.0 kPa). Viral load(VL) has been evaluated by Roche TaqMan RT-PCR(LLOQ<15 IU/ml). Results: Mean age was 61.0 ± 14.2 years, 44% were male, mean LS by Fibroscan® was 6.1 ± 1.8 kPa. Twenty-eight patients(37.3%) had an HOMA>2.5. Two patients were excluded from analysis(one dropped out and the other one had diagnosed genotype 2c at genotyping by sequencing performed after relapse). At 8 weeks(EOT), 71 out of 73 patients(97.3%) had undetectable HCV-RNA, while in two cases HCV-RNA was detectable but with VL<15 IU/ml. Both of them achieved SVR. Two G1b patients relapsed at 12 weeks of follow-up, both with baseline VL>800,000 IU/ml and HOMA score 1.3 and 3.8 respectively. Both had undetectable HCV VL at 4th week and at the EOT. Modified intention-to-treat SVR12 for G1b patients was 71/73(97.3%). Conclusion: In naïve, genotype-1b HCV-infected patients with mild/moderate liver fibrosis, short course of 8 weeks of EBR/GZR appears to achieve high efficacy regardless of features of insulin resistance.

Abstract
Background and aim: Direct Acting Antivirals(DAAs) achieve the highest rate of sustained viral response(SVR) in patients with genotype-1b(G1b) Hepatitis C virus(HCV) infection. Reducing treatment duration can simplify the management and improve adherence of therapy. Patients and methods: The study evaluates the efficacy of 8 weeks of elbasvir/grazoprevir regimen in 75 treatment-naïve(TN), G1b patients with mild-moderate fibrosis(Liver Stiffness by Fibroscan® <9.0 kPa). Viral load(VL) has been evaluated by Roche TaqMan RT-PCR(LLOQ<15 IU/ml). Results: Mean age was 61.0 ± 14.2 years, 44% were male, mean LS by Fibroscan® was 6.1 ± 1.8 kPa. Twenty-eight patients(37.3%) had an HOMA>2.5. Two patients were excluded from analysis(one dropped out and the other one had diagnosed genotype 2c at genotyping by sequencing performed after relapse). At 8 weeks(EOT), 71 out of 73 patients(97.3%) had undetectable HCV-RNA, while in two cases HCV-RNA was detectable but with VL<15 IU/ml. Both of them achieved SVR. Two G1b patients relapsed at 12 weeks of follow-up, both with baseline VL>800,000 IU/ml and HOMA score 1.3 and 3.8 respectively. Both had undetectable HCV VL at 4th week and at the EOT. Modified intention-to-treat SVR12 for G1b patients was 71/73(97.3%). Conclusion: In naïve, genotype-1b HCV-infected patients with mild/moderate liver fibrosis, short course of 8 weeks of EBR/GZR appears to achieve high efficacy regardless of features of insulin resistance.File | Dimensione | Formato | |
