In Japanese blood donors, positivity for antibodies to hepatitis C virus (HCV) ranges from 0.2% in subjects under 20 to 3.9% in those over 50 years. It is estimated that at least 2.3 million Japanese have contracted HCV infection through contaminated blood. HCV carrier state was confirmed by polymerase chain reaction for HCV-RNA in subjects positive for antibodies to more than one viral protein...

Robust data on hepatitis C virus (HCV) population prevalence are essential to inform national HCV services. In 2016, we undertook a survey to estimate HCV prevalence among the adult population in Ireland. We used anonymised residual sera available at the National Virus Reference Laboratory. We selected a random sample comprising persons ≥ 18 years with probability proportional to the general po...

People with hemophilia were formerly at very high risk of infection with hepatitis C virus (HCV). Approximately 20% of HCV-infected patients spontaneously clear the virus. To identify correlates of spontaneous clearance of HCV, we studied a cohort of HCV-infected hemophilic subjects without human immunodeficiency virus infection who had never been treated with interferon. Plasma HCV RNA was per...

Hepatitis C is a liver disease caused by infection of the Hepatitis C virus (HCV). Many individuals infected by the virus are unable to resolve the viral infection and develop chronic hepatitis, which can lead to formation of liver cirrhosis and cancer. To understand better how initial HCV infections progress to chronic liver diseases, we characterised the long term pathogenic effects of HCV in...

Approximately 400,000 individuals in the United States are co-infected with hepatitis C virus (HCV) and human immunodeficiency virus type 1 (HIV-1) and it is likely that almost one in two of these subjects consumes alcohol. The majority of these patients suffer an accelerated course of liver disease as manifested by the onset of cirrhosis within 5 to 10 years of developing HCV infection, as wel...

background and aims: hepatitis c virus is one of the viral infections which is mainly transmitted by blood transfusion. patients with thalassaemia frequently need blood transfusion and are in danger of hcv infection. in most cases of infection (85%) the virus evades the immune system and establishes a chronic infection that may lead to cirrhosis and liver carcinoma. liver is the main site of hc...

We have established a cohort of natural viral suppressors (NVS) who can suppress HIV-1 replication to less than 400 copies/ml in the absence of therapy (similar to Elite Controllers/Elite Suppressors). Of the 59 patients currently in the NVS cohort, 45.8% have chronic hepatitis C virus (HCV) infection, thereby presenting a unique opportunity to study immune activation and the interaction betwee...

Chronic hepatitis C might lead to several immunological dysfunctions. Studies have shown a positive association between hepatitis C virus (HCV) infection and psoriasis. These results suggest that the infection may be one of the triggering factors for the development or exacerbation of psoriasis. Here, we present a case of chronic HCV infection with psoriasis who developed exacerbation of skin l...

conclusions snps within the ccr5 gene should be considered as an important factor used in combination with other host gene snps when developing a mathematical model for anticipating response to hcv therapy. background chronic hepatitis c virus (hcv) infection is a globally serious public health issue. objectives in this study, we investigated cc chemokine receptor 5 (ccr5-59029) polymorphism wh...

Hepatitis C virus (HCV) infection is probably the most common chronic viral infection and affects an estimated 180 million people worldwide, accounting for 3% of the global population. Although the liver is considered to be the primary target, extrahepatic manifestations are well recognized among patients with chronic HCV infection. Epidemiological studies have clearly demonstrated a correlatio...
