Ribavirin at a concentration of 30 mug/ml added immediately after infection completely inhibited influenza A/Port Chalmers/1/73 (H(3)N(2)) virus hemagglutinin production in infected MDCK cells. Under these conditions, host cell protein synthesis was inhibited by only 10 to 20%. Polyacrylamide gel electrophoresis of [(35)S]methionine-labeled material from virus-infected cultures confirmed that r...
UNLABELLED This study was aimed to comparison of the effects of the chronic use of the Ribavirin and caffeic acid phenethyl ester (CAPE) on the pancreatic damage and hepatotoxicity in rats. METHODS The rats were given orally 30 mg/kg/day doses of Ribavirin for 30 days, and intraperitoneally 10 μmol/kg doses of CAPE. The 37 rats were divided into 4 groups: (I) Control (n=7), (II) Ribavirin (R)...
Adenovirus infections are a frequent and serious complication following allogeneic haematopoietic stem cell transplantation (HSCT). The antiviral drugs cidofovir and ribavirin have been used as first-line therapy for disseminated infections with variable results. In the present study, in vitro susceptibility to these two drugs was evaluated on HEp-2 cells in adenovirus reference strains represe...
chronic hepatitis c might lead to several immunological dysfunctions. studies have shown a positive association between hepatitis c virus (hcv) infection and psoriasis. these results suggest that the infection may be one of the triggering factors for the development or exacerbation of psoriasis. here, we present a case of chronic hcv infection with psoriasis who developed exacerbation of skin l...
Treatment of chronic hepatitis C with type I interferons and ribavirin can be associated with exacerbation of hepatitis and sometimes liver decompensation. We report two patients with chronic hepatitis C virus infection who experienced a severe increase of bilirubin levels of up to 17 times upper the limit of normal value in the absence of deterioration of hepatic function during therapy with p...
Ribavirin is used in the treatment of respiratory syncytial virus (RSV) in high-risk patients, including patients who have undergone hematopoietic stem cell transplantation, to reduce mortality from RSV pneumonia. It is classified as a hazardous drug with potential for carcinogenicity and teratogenicity. Very few recent studies have examined the risk of exposure, and recommendations for exposur...
UNLABELLED Ebola virus (EBOV) is an RNA virus that can cause hemorrhagic fever with high fatality rates, and there are no approved vaccines or therapies. Typically, RNA viruses have high spontaneous mutation rates, which permit rapid adaptation to selection pressures and have other important biological consequences. However, it is unknown if filoviruses exhibit high mutation frequencies. Ultrad...
Exposure (10 passages) of type 1 herpesvirus to ribavirin or idoxuridine in Vero cells results in resistance to idoxuridine, but not to ribavirin.
BACKGROUND The interferon-free regimen of ABT-450 with ritonavir (ABT-450/r), ombitasvir, and dasabuvir with or without ribavirin has shown efficacy in inducing a sustained virologic response in a phase 2 study involving patients with hepatitis C virus (HCV) genotype 1 infection. We conducted two phase 3 trials to examine the efficacy and safety of this regimen in previously untreated patients ...
BACKGROUND The standard care of treatment of interferon plus ribavirin (plus protease inhibitor for genotype 1) are effective in 50 % to 70 % of patients with CHC. Several new treatments including Harvoni, Olysio + Sovaldi, Viekira Pak, Sofosbuvir-based regimens characterized with potent inhibitors have been approved by the Food and Drug Administration (FDA) providing more options for CHC patie...
