BACKGROUND Our objective was to use an adapted RT-PCR technique to assess the presence of hepatitis C virus (HCV) in semen and also in different density gradient semen fractions collected from men with chronic viral hepatitis participating in an assisted reproduction programme. METHODS This study included 50 semen samples from 35 HCV(+) men, with active viral replication assessed by RT-PCR, c...

Non-A, non-B hepatitis viruses have been implicated as the etiological agent(s) in up to 60% of patients with fulminant hepatitis. These agents are reported to induce a higher mortality than other causes of fulminant hepatitis. Hepatitis E virus (HEV) and hepatitis C virus (HCV) at present constitute the major identifiable non-A, non-B hepatitis agents. Of these, HEV has been established as the...

Dialysis patients are at risk for contracting blood-borne infections, including hepatitis viruses (HBV and HCV). The aim of this study was to assess the prevalence of HBV and HCV infection among hamodialysis patients in Bahrain and Saudi Arabia. Study subjects comprised 81 Bahraini and 34 Saudi dialysis patients, and as control 7714 Bahraini and 2330 Saudi blood donors. Serologic markers of HBV...

BACKGROUND Hepatitis C virus (HCV) infection is highly prevalent in dialysis patients. To further characterize HCV infection in this patient population, we studied the distribution of viral genotypes in 55 patients undergoing chronic dialysis treatment with seropositivity for HCV markers. METHODS Thirty-two of 55 (58%) patients showed HCV RNA in the serum using reverse transcription polymeras...

Hepatitis C virus (HCV) infection is widespread and responsible for more than 60% of chronic hepatitis cases. HCV presents a genetic variability which has led to viral classification into at least 6 genotypes and a series of subtypes. These variants present characteristic geographical distribution, but their association with different responses to treatment with interferon and severity of disea...

Hepatitis C virus (HCV) was found to replicate in monocytes/macrophages particularly in patients with human immunodeficiency virus type 1 (HIV-1) infection. This study was undertaken to determine whether HIV facilitates HCV infection of native human macrophages in vitro. Monocytes/macrophages were collected from healthy donors, infected with HIV M-tropic molecular clone, and then exposed to HCV...

A heteroduplex tracking assay (HTA) was developed for genetic analyses of the hepatitis C virus (HCV) using single-stranded probes from the core (C)/E1 region. Nucleotide sequencing of reverse transcriptase (RT)-PCR products from 15 Italian dialysis patients confirmed the specificity and accuracy of the HTA genotyping method, which identified 5 of 15 (33.3%) 1b, 7 of 15 (46.7%) 3a, and 3 of 15 ...

Hepatitis C virus (HCV) is thought to have a strong tropism for hepatic tissue but also replicative intermediates are found in extrahepatic tissues suggesting active viral replication in these cells. The aim of the study is to confirm that HCV can infect and replicate in the peripheral blood mononuclear cells (PBMCs) as one of the possible sites of extrahepatic hepatitis C virus replication dur...
