BACKGROUND Hepatocellular carcinoma (HCC) is one of the most common cancers in the world. The geographical prevalence varies considerably in different countries and Scotland is regarded as an area of low risk for the disease. AIMS To assess the association between chronic hepatitis C infection (HCV) and HCC in a population of patients presenting to a single hospital. PATIENTS One hundred an...
To investigate risk factors for HCV infection according to the genotype, we studied 178 patients positive for HCV-PCR and 226 controls that were negative for the anti-HCV antibody. One hundred and twenty five controls (community control) were recruited from spouses of HCV-PCR-positive patients and the other 101 from hospital visitors (hospital control). HCV genotyping was performed by PCR, and ...
CONTEXT Hepatitis C virus (HCV) infection is a major public health issue worldwide, including Iran. The new direct-acting antiviral agents (DAAs) with high efficacy have changed the landscape of HCV treatment. This guideline provides updated recommendations for clinical management of HCV infection in Iran. EVIDENCE ACQUISITION The recommendations of this guideline are based on international a...
BACKGROUND & AIMS We performed a phase 2 trial of the efficacy and safety of 4, 6, and 8 weeks of sofosbuvir, given in combination with the NS5A inhibitor velpatasvir and the NS3/4A protease inhibitor GS-9857, in patients with hepatitis C virus (HCV) infection. METHODS We enrolled 161 treatment-naïve or previously treated patients infected with HCV genotypes 1 or 3 with or without compensated...
Available commercial assays may yield inaccurate hepatitis C virus (HCV) genotype assignment in up to 10% of cases. We investigated the cost-effectiveness of re-evaluating HCV genotype by population sequencing, prior to choosing a direct acting antiviral (DAA) regimen. Between March and September 2015, HCV sequence analysis was performed in order to confirm commercial LiPA-HCV genotype (Versant...
BACKGROUND AND AIMS The prevalence and severity of liver steatosis are higher in patients infected with genotype 3 hepatitis C virus (HCV) than in patients infected with other genotypes. HCV core protein is known to affect lipid metabolism, inducing lipid droplet accumulation both in vitro and in vivo. An in vitro cellular model was used to investigate whether an HCV core protein with residues ...
We examined the frequency of HCV-RNA in saliva samples from anti-HCV positive patients. Both plasma and saliva samples from 39 HCV patients (13 with normal liver enzymes, 19 with abnormal liver enzymes and 13 with cirrhosis) were investigated. Stimulated saliva and fresh plasma were centrifuged (900 x g,10 min) and stored at -70 degrees C, after the addition of guanidine isothiocyanate RNA extr...
BACKGROUND Recent data suggest that the prevalence of genotype 4 HCV strains among Spanish carriers is increasing. OBJECTIVE To assess changes in the prevalence of HCV genotypes in Spain during the last nine years. METHODS HCV RNA was amplified by the polymerase chain reaction from 3161 serum samples from unselected, anti-HCV-positive individuals, and the HCV genotype was identified by a re...
Following a survey of hepatitis C virus (HCV) infection recently carried in central Africa (Gabon), we cloned and sequenced PCR products of the 5' non-coding and capsid-encoding regions of HCV RNA from three randomly selected HCV RNA-positive Gabonese subjects. In the capsid-encoding region, the identity between the three Gabonese isolates was 91 to 98%. The three Gabonese sequences showed a di...
It is unclear whether serum ALT levels or virological characteristics of hepatitis C virus(HCV) including HCV genotypes and HCV RNA titers, can reflect the degree of histological injury in chronic hepatitis C. The aim of this study was to investigate the relationships between the levels of histological damage and serum ALT levels, HCV genotypes or circulating HCV RNA titers in chronic hepatitis...
