Aim: The development of hepatocellular carcinoma (HCC) is reduced after interferon based treatment in patients with chronic hepatitis C (CHC). A new therapy using direct-acting antiviral agents (DAA) has been widely applied since 2014 for CHC. The purpose of this study is to investigate the efficacy, safety and development of HCC after DAA treatment. Methods: The authors enrolled 33 consecutive...

The risk of hepatocellular carcinoma (HCC) development is reduced following viral elimination by interferon therapy in chronic hepatitis C patients. However, the risk in patients treated with interferon-free direct-acting antivirals (DAAs) is unknown. We evaluated chronic hepatitis C patients who achieved viral eradication by pegylated-interferon plus ribavirin (PEG-IFN/RBV, n = 244) or daclata...

Direct-acting antiviral agents (DAA) for hepatitis C virus (HCV) are not effective for hepatitis B virus (HBV), which may be suggestive of reactivation of anti-HBe hepatitis during interferon (IFN)-free DAA therapy in HBV/HCV co-infected patients with inactive HBV. A 69-year-old male patient was diagnosed with chronic hepatitis due to HBV/HCV co-infection with serum levels of alanine aminotrans...

Three hepatitis C virus (HCV) inhibitors, asunaprevir (ASV; BMS-650032), daclatasvir (DCV; BMS-790052), and BMS-791325, each targeting a different nonstructural protein of the virus (NS3, NS5A, and NS5B, respectively), have independently demonstrated encouraging preclinical profiles and are currently undergoing clinical evaluation. Since drug-resistant variants have rapidly developed in respons...

The combination of pegylated interferon (PEG-IFN) and ribavirin (RBV), the current therapy for hepatitis C virus (HCV) infection, has saved the lives of many HCV-infected patients. Direct-acting antivirals (DAAs) target several sites of HCV nonstructural proteins, resulting in the cessation of viral replication. The first NS3/4A protease inhibitors consisted of boceprevir and telaprevir, which ...

BACKGROUND AND AIM There is insufficient research on whether direct-acting antiviral (DAA) therapy can improve liver fibrosis in patients with chronic hepatitis C virus (HCV). We evaluated sequential changes in liver stiffness using shear wave elastography in patients with HCV who received DAA therapy. METHODS A total of 210 patients with HCV who received daclatasvir and asunaprevir therapy a...
