Evaluation of the prognostic value of liver stiffness in patients with hepatitis C virus treated with triple or dual antiviral therapy: A prospective pilot study
Abstract
To evaluate the association between liver stiffness (LS) prior to the initiation of dual/triple therapy and viral response. LS was measured in all patients before treatment was administered. The therapeutic approach was based on hepatic, virological, and immunological evaluations and considered the fact that patients with severe fibrosis (F3) or compensated cirrhosis (F4) in Child-Pugh class A are the primary candidates for triple therapy. In total, 65 hepatitis C virus (HCV) patients were treated with Peg-interferon/ribavirin (Peg-IFN/RBV); 24 patients were classified as genotypes 1/4 (36.92%), and 41 patients were classified as genotypes 2/3 (63.08%) (dual therapy). In addition, 20 HCV treatment-experienced genotype 1 patients were treated with PegIFN-RBV and boceprevir (triple therapy). Wilcoxon rank-sum tests were used to compare the groups. LS significantly differed between dual therapy and triple therapy (P = 0.002). The mean LS value before dual therapy treatment was 8.61 ± 5.79 kPa and was significantly different between patients achieving a sustained virologic response (SVR) 24 weeks after therapy and those who did not (7.23 ± 5.18 kPa vs 11.72 ± 5.99 kPa, respectively, P = 0.0003). The relative risk of non-response to...Continue Reading
