Short-term antiviral efficacy of BILN 2061, a hepatitis C virus serine protease inhibitor, in hepatitis C genotype 1 patients.

Background And Aims: Novel, potent, and well-tolerated hepatitis C virus (HCV) drugs are needed. BILN 2061 is a potent and specific inhibitor of HCV serine protease in vitro. Preclinical toxicology data and studies in healthy volunteers supported the administration of BILN 2061 to patients with HCV infection.

A physician with a positive hepatitis C virus RNA test after a needlestick injury.

Needlestick accidents continue to be a hazard for healthcare workers. We report the development of acute hepatitis C infection in a physician after needlestick injury. Hepatitis C virus (HCV)-RNA, seroconversion and a raised plasma alanine aminotransferase (ALAT) level were found in plasma three months after the accident.

HGV/GB virus C transmission by blood components in patients undergoing open-heart surgery.

Background: To establish the rate of HGV/GB virus C (GBV-C) transmission by blood components in open-heart surgery patients.

Study Design And Methods: From 55 patients receiving blood components, sera were collected before and 2, 4, 6, 8, 10, 12, 16, 20, 26, and 32 weeks after heart surgery. Serum samples from patients and implicated blood donations were tested for HGV/GBV-C RNA by PCR.

An NS3 protease inhibitor with antiviral effects in humans infected with hepatitis C virus.

Hepatitis C virus (HCV) infection is a serious cause of chronic liver disease worldwide with more than 170 million infected individuals at risk of developing significant morbidity and mortality. Current interferon-based therapies are suboptimal especially in patients infected with HCV genotype 1, and they are poorly tolerated, highlighting the unmet medical need for new therapeutics. The HCV-encoded NS3 protease is essential for viral replication and has long been considered an attractive target for therapeutic intervention in HCV-infected patients.

Viral kinetics of hepatitis C virus RNA in patients with chronic hepatitis C treated with 18 MU of interferon alpha daily.

Background: A rapid decrease of hepatitis C virus (HCV) RNA is interferon (IFN) dose-dependent, and a 3-log decline of HCV-RNA is a strong predictor of sustained virological response. In this study, viral kinetics of HCV RNA in patients treated with 18 MU interferon alpha (IFN-alpha) daily for 2 weeks are presented.

Methods: Thirteen treatment-naive patients with chronic hepatitis C received 6 MU of IFN-alpha2a every 8 h for 2 weeks.

Performance of the New Bayer VERSANT HCV RNA 3.0 assay for quantitation of hepatitis C virus RNA in plasma and serum: conversion to international units and comparison with the Roche COBAS Amplicor HCV Monitor, Version 2.0, assay.

We have evaluated the VERSANT HCV RNA 3.0. Assay (HCV 3.
