An assay based on reverse transcription coupled with the polymerase chain reaction (RT-PCR) was used for the detection of hog cholera virus (HCV) and bovine virus diarrhoea virus (BVDV) in cell culture. In this study, a precipitate of the supernatants derived from cell cultures infected with HCV and BVDV was used in RT reactions, in place of extracted viral RNA. Both RT and PCR were performed u...

We localized HCV C-100 protein in liver biopsies of 15 patients with chronic hepatitis C using immunohistochemistry. The results were compared to serum, tissue extract analysis of HCV RNA and in situ RT-PCR described in a previous study. HCV was detected in 80% of the sera tested, in 40% of the tissue extracts and in 80% and 60% of the tissue sections tested by immunohistochemistry and in situ ...

It is presumed that resolution of hepatitis C, as evidenced by normalization of liver function tests and disappearance of hepatitis C virus (HCV) RNA from serum, as determined by conventional laboratory assays, reflects virus eradication. In this study, we examined the expression of the HCV genome in the sera, peripheral blood mononuclear cells (PBMC), and, on some occasions, monocyte-derived d...

AbstractObjectives Porto Alegre, in south Brazil, has one of the highest hepatitis C virus (HCV) infection rates country (84.4 cases/100 000 2018). Prenatal screening HCV, however, not been routinely offered. Methods A longitudinal study pregnant women with HCV and their infants was conducted between January 2014 December 2018. Screening for antibodies offered to all ...

Background: Accumulative research is in progress to clarify clinical aspects of GBV-C. The possibility of interaction between HCV and GBV-C as well as its consequence on development of liver diseases is the most important clinical aspect which encourages researchers to develop a rapid and cost effective technique for simultaneous detection of both viruses. Methods: In this study, a SYBR Green r...

Even with the most advanced 3rd-generation assays, the serologic window period of hepatitis C virus (HCV) is approximately 74 days. HCV RNA detection would reduce the risk of transmission during this period. Furthermore, quantitation of HCV RNA is necessary for proper planning of treatment, monitoring disease progression, and assessing response to antiviral therapy. We have standardized an in-h...

PURPOSE To evaluate the role of core antigen (Ortho trak-C assay) as a marker of active HCV infection in comparison to HCV RNA as detected by reverse transcription polymerase chain reaction (RT-PCR). METHODS This evaluation was carried out during January 2000 to December 2003 in HCV infected individuals who were treatment naomicronve or were on anti-viral therapy. Additionally, sequential pla...

Hepatitis C virus (HCV) infection is the major cause of chronic liver disease after renal transplantation (RT), which reduces both graft and patient survival. After RT, the most widely used approach is interferon (IFN)-based therapy of hepatitis C which may be unsatisfactory with both poor efficacy and an increasing risk of allograft rejection. Thus, it is not recommended unless patients develo...

results of 45 patients, 4 (8.9% [95% ci: 4.4-15.6]) had detectable genomic hcv-rna in their pbmc specimens. hcv genotypes were determined in the pbmcs of these subjects showed that 2 (50.0%) subjects with occult hcv infection had hcv subtype 3a, and 2 (50.0%) had hcv subtype 1b. conclusions this study found that 8.9 % of the iranian candidates for liver transplant with cryptogenic cirrhosis had...
