The translation initiation factor eIF4E is an oncogene that is commonly overexpressed in primary breast cancers and metastases. In this article, we report that a pharmacologic inhibitor of eIF4E function, ribavirin, safely and potently suppresses breast tumor formation. Ribavirin administration blocked the growth of primary breast tumors in several murine models and reduced the development of l...

Treatment of naive patients with chronic hepatitis C has already been reviewed in international consensus meetings [1, 2]. The first consensus was held in Paris and standard interferon in combination with ribavirin was judged to be the best treatment for naive patients [1]. Later in 2002 the National Institutes of Health (NIH) consensus meeting stated that pegylated interferon in combination wi...

Parrot bornavirus 4 is an etiological agent of proventricular dilatation disease, a fatal neurologic and gastrointestinal disease of psittacines and other birds. We tested the ability of ribavirin, an antiviral nucleoside analog with antiviral activity against a range of RNA and DNA viruses, to inhibit parrot bornavirus 4 replication in duck embryonic fibroblast cells. Two analytical methods th...

Retrospective analysis of 303 patients who underwent allogeneic hematopoietic stem cell transplantation identified 35 (11.5%) with adenovirus infection. Among them, 22 received specific therapy. As first-line therapy, 18 were treated with intravenous ribavirin, 3 with cidofovir, and 1 with vidarabine. Moreover, 2 received donor leukocyte infusion in combination with ribavirin, and 1 received it...

BACKGROUND Ulcerative colitis is a lifelong, immunologically mediated disease. Direct-acting antivirals (DAAs) are now available for the treatment of chronic hepatitis C virus (HCV) infection. An interferon-free regimen appears useful, safe and effective for many patients for whom interferon-based treatment is contraindicated. CASE PRESENTATION We studied a 56-year-old treatment-naïve Japanes...

Chronic hepatitis C virus (HCV) infection causes end-stage liver diseases and hepato cellular carcinoma. In the USA, Canada, and Japan, simeprevir - one of the second-generation HCV NS3/4A protease inhibitors - in combination with peginterferon α-2a or 2b plus ribavirin has recently been approved for HCV genotype 1-infected patients and is now used in daily clinical practice. This review summar...

Actinomycin D inhibited the yield of influenza virus hemagglutinin from MDCK cells infected at high multiplicity, but had little effect on the yield of parainfluenza virus hemagglutinin. In similar hemagglutinin yield experiments, ribavirin was only slightly more active (threefold) against influenza virus than against parainfluenza virus replication. In plaque inhibition experiments, ribavirin ...

Health care workers (HCW) are exposed to ribavirin aerosol during therapy of infants with respiratory syncytial virus infections. To assess the degree of HCW exposure, we analyzed air samples from patient rooms and HCW personal breathing zones during ribavirin aerosol delivery by ventilator (two samples), oxygen hood (two samples), and a new vacuum exhaust hood (four samples). HCW exposure to r...
