BACKGROUND: Chronic hepatitis C virus (HCV) infection is widespread in the world and highly prevalent in Egypt. Some reports suggest that HCV chronic infection could alter seminal parameters and reproductive hormones, so chronic HCV infection may influence the male fertility. Objective: we conducted this study to assess the possible effect of chronic HCV infection and its antiviral treatment on...

In immuno-competent individuals, the natural course of chronic hepatitis C virus (HCV) infection is highly variable and 5%-30% of patients develop cirrhosis over 20 years. Co-infection with HCV and human immunodeficiency virus (HIV) is an important prognostic factor and associated with more frequent and accelerated progression to cirrhosis. Until recently HIV/AIDS-related complications were lif...

Currently available serological assays for detection of antibodies to hepatitis C virus (HCV) cannot reliably discriminate acute from chronic HCV infection. We developed a multiplexed, flow-cytometric microsphere immunoassay to measure anti-HCV-IgG reactivities to the core, NS3, NS4, and NS5 HCV recombinant proteins and applied it to 99 serum samples from 24 anti-HCV seroconverters and 141 anti...

Treatment with interferon alfa combined with ribavirin is successful in approximately 40% to 45% of patients with chronic hepatitis C viral infection (HCV). However, response rates are disappointing in patients who are difficult to treat, such as those infected with HCV genotype 1, high viral load, or advanced liver fibrosis. In addition, low tolerability and significant side effects of therapy...

Hepatitis C virus (HCV) is a positive-stranded RNA virus that infects approximately 130-170 million people worldwide. In 2005, the first HCV infection system in cell culture was established using clone JFH-1, which was isolated from a Japanese patient with fulminant HCV infection. JFH-1 replicates efficiently in hepatoma cells and infectious virion particles are released into the culture supern...

Chronic hepatitis C virus (HCV) infection remains a serious burden to public health worldwide. Currently, HCV-infected patients could undergo antiviral therapy by giving pegylated IFN-alpha with ribavirin. However, this therapy is only effective in around 50% of patients with HCV genotype 1, which accounts for more than 70% of all HCV infection, and it is not well tolerated for most patients. M...

Hepatitis C virus (HCV) is a unique virus whose life cycle is closely associated with lipoprotein metabolism [1, 2, 3]. Assembly of HCV particles, formation of HCV-virions, is closely connected to the formation of lipid droplets in hepatic cells that may serve as an assembly platform [1, 4]. In addition, the production of HCV particles is tightly linked to the very low-density lipoprotein (VLDL...

Chronic hepatitis C virus (HCV) infection has been associated with various extrahepatic manifestations, including autoimmune cytopenias. Primary autoimmune haemolytic anaemia (AIHA) has been reported as an unusual extrahepatic manifestation. Combination therapy with pegylated interferon (PEG-IFN) and ribavirin (RBV) is the current treatment of choice for chronic HCV infection. However, this the...

In order to clarify the risk factors of hepatitis C virus (HCV) infection, past medical histories, family histories of liver disease, and lifestyle factors (smoking and drinking habits) were compared between anti-HCV positive cases and anti-HCV negative controls. Studies were 433 anti-HCV positive cases and 298 negative controls, all of whom were out-patients with chronic hepatitis or liver cir...

Most haemophiliacs treated with non-virally-inactivated clotting factor concentrates have been infected with hepatitis C virus (HCV). We have studied the natural history of chronic HCV infection by following all 138 HCV-positive patients from our centre for periods of up to 28 years. As well as the clinical and biochemical characteristics, we studied 116 liver samples from 63 patients obtained ...
