BACKGROUND Patients exposed to hepatitis C virus (HCV) may develop chronic infection with viremia. The diagnosis of this condition requires the use of several laboratory tests in algorithms tailored to the population and resources available for each laboratory. AIM We compared the diagnostic efficacy of two diagnostic algorithms for the identification of viremic patients with HCV. One based o...
A possible causative role for the recently discovered hepatitis C virus (HCV) in the development of hepatocellular carcinoma (HCC) was investigated by assay of sera from HCC patients in Japan for antibodies to a recombinant HCV antigen and to hepatitis B virus (HBV) antigens. Among the 253 HCC patients examined, 156 (61.7%) had no serum markers of either a previous or a current HBV infection (g...
Dr. Marcia da Suva Cardoso, German Red Cross Blood Bank and, Department of Transfusion , Medicine, University of Ulm, Helmholzstrasse 10, D-89081 Ulm (Germany) Dear Sir, In order to establish the prevalence of HCV infectious patients in the Dialysis Unit of the Board of Dialysis of Transplantation Ulm, we investigated a group of 195 patients by HCV RT/PCR. For this purpose we used a well-establ...
The positive predictability of anti-HCV ELISA is low, especially, in blood donors and in healthy populations. False positive anti-HCV results pose some difficulties in medical practice and in blood screening. The aim of this study was to identify the factors associated with true hepatitis C virus (HCV) infection among anti-HCV ELISA-positives. A case-control analysis was conducted using 354 sub...
We compared hepatitis B virus (HBV) surface antigen, anti-hepatitis C virus (HCV) antibody, and HCV RNA quantification in frozen and freeze-dried serum samples to assess the usefulness of freeze-dried sera for detection of HBV and HCV. The results indicated that freeze-dried sera as well as frozen sera can be useful for serological and molecular biological analyses of HBV and HCV.
Amplification of hepatitis C virus (HCV) RNA from blood detected occult HCV infections in 30.9% of 210 HCV-seronegative dialysis patients with abnormal liver enzyme levels that had evaded standard HCV testing practices. Isolated HCV core-specific antibody detection identified three additional anti-HCV screening-negative patients lacking HCV RNA amplification in blood who were considered potenti...
BACKGROUND Non-organ specific autoantibodies are highly prevalent in patients with chronic hepatitis C (HCV). Among them, anti-liver kidney microsomal type 1 (LKM1) antibody--the serological marker of type 2 autoimmune hepatitis (AIH-2)--is detected in up to 11% of the HCV-infected subjects. On the other hand, anti-liver cytosol type 1 antibodies (anti-LC1)--either in association with anti-LKM1...
Chronic hepatitis C is a serious liver disease that often results in cirrhosis or hepatocellular carcinoma. The aim of this study was to assess the association of human leukocyte antigen-DP (HLA-DP) variants with risk of chronic hepatitis C virus (HCV) or anti-F antibody generation. We selected two single nucleotide polymorphisms (SNPs) in a region including HLA-DPA1 (rs3077) and HLA-DPB1 (rs92...
Discrepancy between Serological and Virological Analysis of Viral Hepatitis in Hemodialysis Patients
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...
abstract background thalassemia patients that are conventionally treated by a regular transfusion regimen are exposed to blood born viral infections.the aim of this study was to investigate the seroprevalence of hepatitis b virus (hbv), hepatitis c virus (hcv) , and human immunodeficiency virus(hiv) among all multitransfused thalassemia patients in west north of iran. material and methods a ret...
