| 6 | Pre-treatment prediction of response to peginterferon plus ribavirin in chronic hepatitis C genotype 3显示文摘AIM: To evaluate pre-treatment factors associated with sustained virological response(SVR) in patients with hepatitis C virus(HCV) genotype 3 treated with peginterferon and ribavirin(RBV). METHODS: We retrospectively analyzed treatment naive, mono-infected HCV genotype 3 patients treated with peginterferon and RBV. Exclusion criteria included presence of other liver disease, alcohol consumption and African American or Asian ethnicity. The variables collected and compared between patients who achieved an SVR and patients who did not were as follows: gender, age, fibrosis stage, diabetes, body mass index,steatosis, INFL3 polymorphism, pre-treatment HCVRNA, type of peginterferon, RBV dose and adherence. RESULTS: A total of 107 patients treated between June, 2004 and March, 2013 were included. Mean treatment duration was 25.1(± 1.8) wk. Overall, 58%(62/107) of the patients achieved an SVR and 42%(45/107) did not. In the multivariate logistic regression analysis, pre-treatment HCV-RNA ≥ 600000 UI/m L(OR = 0.375, 95%CI: 0.153-0.919, P = 0.032) and advanced fibrosis(OR = 0.278, 95%CI: 0.113-0.684,P = 0.005) were significantly associated with low SVR rates. In patients with pre-treatment HCV-RNA ≥600000 UI/m L and advanced fibrosis, the probability of achieving an SVR was 29%(95%CI: 13.1-45.2).In patients with pre-treatment HCV-RNA < 600000UI/m L and mild to moderate fibrosis, the probability of achieving an SVR was 81%(95%CI: 68.8-93.4).CONCLUSION: In patients with HCV genotype 3infections the presence of advance fibrosis and high pre-treatment viral load might be associated with poor response to peginterferon plus RBV. These patients could benefit the most from new direct antiviral agentsbased regimes. | Sebastian Marciano Silvia M Borzi Melisa Dirchwolf Ezequiel Ridruejo Manuel Mendizabal Fernando Bessone Maria E Sirotinsky Diego H Giunta Julieta Trinks Pablo A Olivera Omar A Galdame Marcelo O Silva Hugo A Fainboim Adrian C Gadano | 2015 | World Journal of Hepatology2015，7，4： | 1 |
