摘      要：AIM To evaluate new therapies for hepatitis C virus(HCV), data about real-world outcomes are *** Outcomes of 223 patients with genotype 1 HCV who started telaprevir-or boceprevir-based triple therapy(May 2011-March 2012) at the Mount Sinai Medical Center were analyzed. Human immunodeficiency viruspositive patients and patients who received a liver transplant were excluded. Factors associated with sustained virological response(SVR24) and relapse were analyzed by univariable and multivariable logistic regression as well as classification and regression trees. Fast virological response(FVR) was defined as undetectable HCV RNA at week-4(telaprevir) or week-8(boceprevir). RESULTS The median age was 57 years, 18% were black, 44% had advanced fibrosis/cirrhosis(FIB-4 ≥ 3.25). Only 42%(94/223) of patients achieved SVR24 on an intention-totreat basis. In a model that included platelets, SVR24 was associated with white race [odds ratio(OR) = 5.92, 95% confidence interval(CI): 2.34-14.96], HCV sub-genotype 1b(OR = 2.81, 95%CI: 1.45-5.44), platelet count(OR = 1.10, per x 104 cells/μL, 95%CI: 1.05-1.16), and IL28 B CC genotype(OR = 3.54, 95%CI: 1.19-10.53). Platelet counts 135 x 103/μL were the strongest predictor of SVR by classification and regression tree. Relapse occurred in 25%(27/104) of patients with an end-oftreatment response and was associated with non-FVR(OR = 4.77, 95%CI: 1.68-13.56), HCV sub-genotype 1a(OR = 5.20; 95%CI: 1.40-18.97), and FIB-4 ≥ 3.25(OR = 2.77; 95%CI: 1.07-7.22). CONCLUSION The SVR rate was 42% with telaprevir-or boceprevirbased triple therapy in real-world practice. Low platelets and advanced fibrosis were associated with treatment failure and relapse.
