The availability of a highly accurate, rapid, point-of-care test for hepatitis C virus (HCV) may be useful in addressing the problem of under-diagnosis of HCV, by increasing opportunities for testing outside of traditional clinical settings. A new HCV rapid test device (OraQuick® HCV Rapid Antibody Test), approved recently in Europe for use with venous blood, fingerstick blood, serum, plasma, o...
Immunosuppression from human immunodeficiency virus (HIV) may impair antibody formation, and false-negative hepatitis C virus antibody (anti-HCV) tests have been reported in individuals coinfected with HIV and HCV. It is unknown if the frequency of false-negative tests is sufficiently high to change screening recommendations in this setting. Thus, the prevalence of false-negative results for an...
Acute hepatitis C virus (HCV) is typically defined as new viremia and antibody seroconversion. Rates and immunologic correlates of hepatitis C clearance have therefore been based on clearance of viremia only in individuals who initially had an antibody response. We sought to characterize the immunological correlates of clearance in patients with acute hepatitis C and their sexual contacts. We p...
background: hemophilia is a congenital disease resulting in deficiency of clotting factors. for this reason they have a constant need of clotting factors which makes them one of the largest consumers of blood products. through this blood product use, many of these patients have become infected by hepatitis c virus (hcv). we have studied the seroprevalence of anti-hcv antibody and hcv infection ...
Hepatitis C virus (HCV) is the major etiologic agent associated with non-A, non-B hepatitis. This study was designed to assess virologic and serologic markers in hemophiliacs exposed to non-heat-treated and/or virus-inactivated plasma derivatives. Serial bleeds from 48 hemophilic patients were analyzed for the presence of HCV viral RNA sequences as detected by polymerase chain reaction (PCR) an...
Hepatitis C (HCV) virus is recognized as the major cause of what was previously referred to as parenterally acquired (blood-mediated) non-A, non-B hepatitis. A study involving 252 transfused and nontransfused Egyptian children was conducted from November 1990 through February 1991 to determine the prevalence of HCV and the role of blood and blood and blood product transfusions in the spread of ...
To evaluate the clinical feasibility of the antibody titer against a chimeric polypeptide (named Core 518), in which a domain of Core and NS3 of hepatitis C virus (HCV) was fused, ELISA was performed in a total of 76 serum samples. Each serum was serially diluted using two-fold dilution method with distilled water into 10 concentrations. They were all positive for second generation anti-HCV ass...
conclusions according to the results, it was found that hcv high prevalent genotype in zanjan is subtype 3a. analysis of the results provides identification of certain hcv genotypes, and these valuable findings could affect the type and duration of the treatment. results samples indicated 216 bp bands on 2% agarose gel. analyses of the results demonstrated that the most dominant subtype was 3a ...
OBJECTIVE To estimate the cost, effectiveness, and cost effectiveness of HIV and HCV screening of injection drug users (IDUs) in opioid replacement therapy (ORT). DESIGN Dynamic compartmental model of HIV and HCV in a population of IDUs and non-IDUs for a representative U.S. urban center with 2.5 million adults (age 15-59). METHODS We considered strategies of screening individuals in ORT fo...
Viral entry requires co-operative interactions of several host cell factors. Interferon (IFN) and the IFN-stimulated genes (ISGs) play a central role in antiviral responses against hepatitis C virus (HCV) infection. We examined the effect of interferon-α inducible protein 6 (IFI6) against HCV infection in human hepatoma cells. HCV RNA level or infectious foci were inhibited significantly by ect...
