BACKGROUND The aim of the evaluation was to investigate the relevance of the HCV-core antigen testing for the diagnosis and monitoring of HCV infections in the daily routine. Up to now, most of the serological diagnostics was performed as determination of antibodies while the determination of activity and the monitoring of antiviral therapy were checked by HCV RNA PCR. METHODS The routine req...

In order to investigate hepatitis C virus (HCV) persistence and replication in peripheral blood mononuclear cells (PBMC) from a group of haemophilic individuals, HCV production and release to PBMC culture supernatants (SNs) from HCV singly infected patients and HIV/HCV co-infected patients was studied. HCV RNA+ SNs were found more frequently from HIV/HCV co-infected individuals (89.5 %) with po...

Hepatitis C virus (HCV), a major etiologic agent of hepatocellular carcinoma, presently infects approximately 400 million people worldwide, making the development of protective measures against HCV infection a key objective. Here we have generated a recombinant vesicular stomatitis virus (VSV), which expresses the HCV structural proteins, by inserting the contiguous Core, E1, and E2 coding regi...

BACKGROUND/OBJECTIVES Guidelines for optimized HCV screening are urgently required in Africa, especially for patients infected with HIV, who sometimes show false positive or false negative reactivity in anti-HCV antibody assays. Here, we assessed the usefulness of a fourth-generation HCV Ag-Ab ELISA for the identification of active HCV infection in HIV-positive patients. METHODS This cross-se...

BACKGROUND End-stage renal disease patients on chronic hemodialysis are among high risk groups for hepatitis C virus (HCV) infection for whom routine HCV screening is recommended. Anti-HCV antibody (ab) testing may not be reliable to detect all infected cases because of the blunted ab response due to depressed immune state in these patients. Using a more reliable, cost-effective and non-complex...

Abstract Background Hepatitis C virus (HCV) is a contagious disease that damages the liver over time, eventually leading to cirrhosis and death. Chronic HCV infection regarded as serious health problem worldwide, impacting up 3% of populace killing 300,000 people annually. Quick reproduction driven by non-structural protein 5B (NS5B), which possible target spot for development anti-HCV vaccines...

Hepatocellular carcinoma (HCC) is a typical cancer that has region specified analysis with the incidence of hepatitis C virus (HCV) infection. This study was conducted to improve understanding metabolic alterations associated HCV induced HCC which can open up new strategies monitor high risk HCC. Samples subjects HCV, chronic liver disease (CLD), HCC, and healthy controls (HS) were collected af...

The detection of hepatitis C virus (HCV) in saliva was studied. Twenty-three subjects with chronic HCV infection and 1 subject with acute HCV infection were enrolled in a 21-day study. Roche COBAS Amplicor and Bayer VERSANT HCV RNA qualitative assays were used. For the 23 subjects with chronic HCV infection, 72% of 474 saliva samples were positive (or were imputed to be positive) for HCV RNA. S...

BACKGROUND Accurate quantitative detection of hepatitis C virus (HCV) RNA is critical for diagnosis of acute or chronic HCV infection, and for follow-up of virologic response during HCV targeted therapy. In the present study, traceability and reproducibility of a novel China-certified domestic Sansure HCV RNA diagnostic assay (Sansure, Changsha, Hunan, China) was evaluated and the clinical perf...

Molecular epidemiological studies of hepatitis C virus (HCV) in the Caribbean may help to specify the origin and spread of HCV infection. Indeed, the Caribbean population is intermixed from European and African origins and geographically close to the American continent. We characterized HCV genotypes in the Caribbean island of Martinique. HCV genotypes were analyzed by sequencing or reverse hyb...
