Famciclovir and valaciclovir were approved for use in the treatment of herpes zoster despite controversy over antiviral therapy in zoster due to high costs and uncertain benefits. To explore these issues, a Markov decision model was developed, and the incremental cost effectiveness of antiviral treatment for herpes zoster was estimated using these agents compared with no antiviral therapy. A th...

Background : Hepatitis B virus (HBV) is a non-cytopathic virus, and the hepatocellular injury that occurs as a consequence of HBV infection is mediated by the host antiviral immune response. Subjects with natural tolerance to HBV have minimal or no liver injury despite chronic viremia. We have shown that immune tolerance towards viruses can be induced by oral administration of viral proteins. A...

BACKGROUND Globally, of the 248 million people chronically infected with the hepatitis B virus (HBV), 74 million reside in China. Five oral nucleot(s)ide analogs (NUCs) have been approved for the treatment of chronic hepatitis B (CHB) in China. OBJECTIVES The aims of this study were to determine rates of adherence to NUC therapy in patients with CHB, to identify the self-perceived barriers to...

Introduction. The aim of this study was to assess whether hepatitis B virus drug resistant mutations antedated the widespread use of nucleos(t)ide analogues in treatment naïve patients. A number of reports have suggested that drug resistant mutants can be detected in apparently treatment naïve patients. Study. Fifty deidentified serum samples collected from 1986 to 1992 from patients with repli...

BACKGROUND: All-oral combination therapy is desirable for patients with chronic hepatitis C virus (HCV) infection. We evaluated daclatasvir (an HCV NS5A replication complex inhibitor) plus sofosbuvir (a nucleotide analogue HCV NS5B polymerase inhibitor) in patients infected with HCV genotype 1, 2, or 3. METHODS: In this open-label study, we initially randomly assigned 44 previously untreated pa...
