background three single nucleotide polymorphisms (snps) near interleukin-28b (il-28b) gene were shown to be highly associated with treatment response (svr) in patients with chronic hepatitis c virus (hcv) infection. there is limited data about the role of single and combined il-28b polymorphisms in hcv-infected polish population. objectives this study's aim was to determine predictability of th...

A prospective randomised, double blind, controlled trial was conducted in 52 infants to determine whether recombinant interferon alfa-2a (INF-alpha-2a) would reduce the morbidity of acute bronchiolitis and the respiratory syncytial virus shedding time. All infants had a positive direct antigen immunofluorescence test for respiratory syncytial virus. INF-alpha-2a (50,000 IU/kg/day) or placebo wa...

background egypt has one of the highest (16-8%) prevalence rates of hcv infection in the world. approximately 90% of egyptian hcv isolates belong to a single subtype (4a), which responds less successfully to interferon therapy than other subtypes. studies comparing the efficacy and safety of pegifn alfa-2a and pegifn alfa-2b in treatment-naive hcv-infected patients have shown conflicting result...

We report on two patients with Ph+ chronic myeloid leukemia (CML) in chronic phase who developed severe thrombocytopenia during treatment with interferon-alpha 2A (IFN-alpha 2A). In both cases, we detected the presence of platelet-associated antibodies (PAIg) by autoimmune flow cytometry. We postulated an immune mediated platelet destruction mechanism; corticosteroid therapy was employed and in...

We have recently reported that adenovirus replication is inhibited by human recombinant interferon-gamma, but not by recombinant interferon-alpha, in a dose-dependent manner. The aim of this study was to determine whether the antiviral effect of recombinant interferon-gamma could be linked to interferon-induced alteration at the membrane level, inhibiting either adenovirus penetration of or rel...

Human interferon alpha 2a (hIFNα2a) is a cytokine regulating immune system that has been used in hepatitis and cancer treatments. It has wide biological potency covering antiviral, antiproliferative and immunomodulative activities. This mini review discusses Roferon-A as a prominent commercial product of recombinant hIFNα2a which is produced in bacterial system, Escherichia coli, as therapeutic...
