BACKGROUND A sustained virological response (SVR) rate of 41% has been achieved with interferon alfa-2b plus ribavirin therapy of chronic hepatitis C. In this randomised trial, peginterferon alfa-2b plus ribavirin was compared with interferon alfa-2b plus ribavirin. METHODS 1530 patients with chronic hepatitis C were assigned interferon alfa-2b (3 MU subcutaneously three times per week) plus ...

BACKGROUND The aim of the study was to determine the efficacy and safety of triple therapy with a first-generation protease inhibitor (PI; boceprevir, telaprevir) plus peginterferon alfa-2a or -2b plus ribavirin, and dual therapy (peginterferon alfa-2a or -2b plus ribavirin) in patients with chronic hepatitis C (CHC) in routine clinical practice. METHODS PegBase was an international, prospect...

Ribavirin is a guanosine ribonucleoside analog that displays broad-spectrum anti-viral activity and is currently used for the treatment of some viral infections. Ribavirin has recently been proposed to also be a mimic of the 7-methyl guanosine cap found at the 5' end of mRNAs. To obtain supporting functional data for this hypothesis, we assessed the ability of ribavirin triphosphate to interfer...

We report a 48-year-old man who developed rheumatoid arthritis (RA) after a successful treatment with peg-IFN-alpha plus ribavirin for chronic hepatitis C virus (HCV) infection. He had a history of smoking and a single copy of the HLA-DRB1 shared epitope (SE). In a retrospective analysis, he exhibited the anti-CCP antibodies before the start of IFN plus ribavirin treatment. However, the titers ...

The guanosine analogue ribavirin was tested for antiviral activity in two neural cell lines, human oligodendrocytes and rat glia, against Borna disease virus (BDV) strains V and He/80. Ribavirin treatment resulted in lower levels of virus and viral transcripts within 12 h. Addition of guanosine but not adenosine resulted in a profound reduction of the ribavirin effect. Ribavirin appears to be a...

Sustained virologic response with peg-interferon and ribavirin combination therapy for 48 weeks is still inadequate. Our study examined whether short-term administration of retinol clinically influences the anti-viral activity of interferon early during interferon and ribavirin combination therapy. The control group received 6 MIU of interferon alpha-2b every day for two weeks and then 3 times ...

BACKGROUND Lassa fever (LF) is an acute viral haemorrhagic infection, endemic in West Africa. Confirmatory diagnosis and treatment (ribavirin) is difficult, expensive, and restricted to specialised hospitals. Among confirmed and suspected LF cases, we report on clinical and laboratory features, timing and administration of ribavirin and the relationship with case fatality. METHODS We conducte...

Over the past two decades, ribavirin has been an integral component of treatment for hepatitis C virus (HCV) infection, where it has been shown to improve the efficacy of (pegylated) interferon. However, because of treatment-limiting side effects and its additive toxicity with interferon, the search for interferon- and ribavirin-free regimens has been underway. The recent approvals of all-oral ...

Ribavirin enhances the anti-human immunodeficiency virus activity of 2',3'-dideoxyinosine (ddIno) in MT-4, CEM and peripheral blood lymphocyte cells. Ribavirin causes an increase in the levels of IMP, the presumed phosphate donor for the conversion of ddIno to ddIMP by 5'-nucleotidase. Consequently, ribavirin stimulates the conversion of ddIno to its antivirally active metabolite ddATP. Ribavir...
