CD4+ Treg-cells (regulatory T-cells) probably contribute to the impaired virus-specific T-cell responses in chronic HCV (hepatitis C virus) infection; however, their antigen-specificity has remained elusive. In the present study, we analysed peripheral blood CD4+ Treg-cells in patients with chronic hepatitis C and subjects with self-limited HCV infection and characterized individual Treg-cell c...

Background: Recently, some new viruses have been identified for their association with hepatitis which Torque Teno Mini Virus being among them. The aim of this study was to determine the frequency of Torque Teno Mini Virus in healthy individuals and hepatitis B and C patients in Isfahan, Iran. Materials and Methods: One hundred serum samples of healthy individuals from Isfahan Blood Transfusi...

Up to three million Healthcare Workers are exposed body fluid and resulting bloodborne pathogens each year, causing more than 170 000 HIV infections, two viral hepatitis B (HBV) 0,9 C (HCV) [1]

BACKGROUND AND AIM Prisons in Egypt do not currently screen for blood-borne viruses, and there are no statistics concerning the prevalence of hepatitis C virus, hepatitis B virus or human immunodeficiency virus among prisoners. This study was performed to detect the prevalence of antibodies against hepatitis C, hepatitis B core and human immunodeficiency virus among Egyptian prisoners. METHOD...

background hepatitis c virus (hcv) infection has been explained as a disease that sometimes present with rheumatic manifestations indistinguishable from rheumatoid arthritis. this study has been performed to evaluate the frequency of hepatitis c virus infection in a group of patients with rheumatoid arthritis. patients and methods in this study, during one year, serum samples collected from two...

Acute hepatitis C is often asymptomatic, frequently remains undiagnosed and frequently evolves to chronic hepatitis. Early, short-term interferon treatment is efficacious in acute hepatitis C, and so underscores the importance of an early diagnosis and the need to distinguish acute infection from acute exacerbation of chronic HCV infection. The gold standard for the diagnosis of acute hepatitis...

BACKGROUND AND AIM Viral hepatitis is a health threat for hemodialysis (HD) patients and it may be transmitted during treatment. Some patients categorized to have viral hepatitis were found to be non-viremic. To clarify the discrepancy between the serological tests in HD patients, we conducted the study. METHODS A total of 1681 HD patients was included. Blood samples were analyzed for hepatit...

background& objectives: hepatitis c virus is one of the recently  discovered viruses that tend to  cause chronic liver disease. hepatitis c is one of the most common types of viral  hepatitis, cirrhosis and carcinoma of liver in hemodialysis patients. the most important risk factors of  hepatitis c in dialysis patients are blood transfusion , duration of dialysis and  kidney transplantation .to...

Hepatitis C is a long-term viral infection affecting the liver caused by the hepatitis C virus HCV. Hepatitis C can be silent for years before symptoms appear, and liver damage occurs. The hepatitis C virus is extremely infectious, which means that only a tiny amount of HCV can cause illness. Hepatitis C is a major public health problem worldwide with far-reaching implications because of the ch...

INTRODUCTION Hepatitis C virus (HCV), which was formerly described as the parenterally transmitted form of non-A, non-B hepatitis (NANBH), becomes a chronic disease in 50% of the cases. HCV can also be transmitted through intravenous drug abuse, sexual , and household contact. Hepatitis C virus is a single stranded RNA virus with some structural relations to the flavivirus family. Nucleic acid ...
