Background:Human hepatocellular carcinoma (HCC) cells are largely deficient of argininosuccinate synthetase and thus auxotrophic for arginine. This study aims to investigate the efficacy and pharmacodynamics of pegylated arginine deiminase (ADI-PEG 20), a systemic arginine deprivation agent, in Asian HCC patients.Methods:Patients with advanced HCC who were(More)
Chronic hepatitis C virus (HCV) infection patients exhibit different sustained virological responses (SVRs) following the treatment with pegylated interferon-α (IFN-α) and ribavirin. Genome-wide association studies consistently linked SVR of IFN-α-based therapy to the IL28B single-nucleotide polymorphisms (SNPs) on chromosome 19q.13 in various populations.(More)
BACKGROUND The long-term benefits of interferon-based therapy on preventing cirrhosis at non-cirrhotic stage in chronic hepatitis C patients are not fully clarified. AIM To evaluate the effectiveness of interferon-based therapy regarding to cirrhosis prevention in non-cirrhotic chronic hepatitis C patients. METHODS A total of 1386 biopsy-proven,(More)
To compare the long-term effect of natural lymphoblastoid interferon-alpha (IFN-alpha nl) and recombinant IFN-alpha 2a therapy in patients with chronic hepatitis B, 210 patients in two trials were followed-up for 1.1-15.5 years following the end of therapy. They included 34 patients who received placebo (control), 67 treated with IFN-alpha nl (36 after(More)
Chronic hepatitis B virus (HBV) infection is associated with impairment of HBV-specific immune responses. Recently, it has been shown that regulatory T (Treg) cells downregulate HBV-specific immune responses but their role in chronic hepatitis B is still controversial. We hypothesized that liver injury enhances the influence of Treg cells on HBV-specific(More)
BACKGROUND AND STUDY AIMS To evaluate the efficacy of two different endoscopic hemorrhoidal ligation (EHL) devices for symptomatic internal hemorrhoid. PATIENTS AND METHODS From November 2000 to February 2001, 218 consecutive patients with symptomatic internal hemorrhoids were enrolled. A total of 109 patients were treated with an EHL device 9 mm in(More)
Although hepatitis B virus (HBV) RNA splicing has been reported by many researchers, the clinical significance of this event remains illusive. The present study was designed to investigate the clinical roles of singly spliced HBV-RNA. Liver biopsy tissues obtained from 32 consecutive patients were subjected to reverse transcriptase-polymerase chain reaction(More)
A liver slice culture-based, ex vivo drug suppression assay was developed as a pre-therapeutic predictor for the outcome of antiviral therapy. To investigate its clinical application, 106 consecutive patients with chronic hepatitis C virus (HCV) infection were evaluated. Ex vivo drug suppression assay was performed before administrating a standard course of(More)
Adjuvant pegylated interferon plus ribavirin treatment (PegIFN/RBV) reduces recurrence and prolongs survival in early stage hepatocellular carcinoma (HCC) patients with chronic hepatitis C (CHC) infection receiving resection or ablation. However, the impact of antiviral therapy in intermediate and advanced stage of CHC-HCC patients is uncertain. This study(More)
