BACKGROUND Current treatments for chronic hepatitis B are suboptimal. In the search for improved therapies, we compared the efficacy and safety of pegylated interferon alfa plus lamivudine, pegylated interferon alfa without lamivudine, and lamivudine alone for the treatment of hepatitis B e antigen (HBeAg)-positive chronic hepatitis B. METHODS A total of(More)
Large volume of new data on the natural history and treatment of chronic hepatitis B virus (HBV) infection have become available since 2008. These include further studies in asymptomatic subjects with chronic HBV infection and community-based cohorts, the role of HBV genotype/naturally occurring HBV mutations, the application of non-invasive assessment of(More)
Hepatitis C virus subtype 3a (HCV-3a) originates from Asia and has spread widely among injecting drug users as well as other patient groups in industrialized countries. HCV subtype 3a infection remains highly prevalent and frequently transmitted in the population of intravenous drug users. The objective of this study was to understand better the mechanisms(More)
BACKGROUND Sustained virological response (SVR) is the primary objective in the treatment of chronic hepatitis C (CHC). Results from a recent clinical trial of patients with previously untreated CHC demonstrate that the combination of peginterferon alpha-2a and ribavirin produces a greater SVR than interferon alpha-2b and ribavirin combination therapy.(More)
Induction of curative immune responses by therapeutic vaccination in chronic viral infections such as chronic hepatitis B (CHB) is expected to be facilitated by reduction of viral load by antiviral treatment. In this open label, controlled, randomized study, 195 patients with HBeAg positive CHB were randomized to receive 12 doses of HBsAg with AS02B(More)
BACKGROUND/AIMS Peginterferon alfa-2a plus ribavirin improves sustained virological responses compared with interferon alfa-2b and ribavirin, or peginterferon alfa-2a alone in chronic hepatitis C. We examined the impact of these treatments on health related quality of life (HRQOL). METHODS Patients (n=1121) were randomized to peginterferon alfa-2a weekly(More)
The tumor suppressor gene CDKN2A (MTS1/p16), located on chromosome 9p21, is inactivated in a variety of tumors including melanomas and tumors of the biliary tract, pancreas, and stomach. The aim of the present study was to determine whether this gene is inactivated in hepatocellular carcinoma (HCC). Twenty-three primary HCCs and four HCC cell lines were(More)
UNLABELLED The aims of this study were to evaluate the usefulness of quantitative hepatitis B e antigen (HBeAg) values for predicting HBeAg seroconversion in patients treated with peginterferon alfa-2a and to assess the dynamic changes in quantitative HBeAg during therapy, compared with conventional measures of serum hepatitis B virus DNA. Data were(More)
The Steering Committee for the Prevention and Control of Infectious Diseases in Asia recently conducted a survey of primary-care physicians in Asia, which revealed that many physicians administer boosters in their clinical practice and that there is considerable variation and uncertainty among physicians regarding this practice. This paper serves as a(More)
Hepatitis C is highly prevalent among intravenous drug abusers, but to date research has not widely explicated behavioural risk factors regarding acquisition of infection. The A₁allele of the D₂ dopamine receptor (DRD2) gene is a hypothesized risk factor in the development of severe drug dependence and alcoholism. The present study compares the frequency of(More)
