title: Hepatitis C virus-RNA, immunoglobulin M anti-HCV and risk factors in haemodialysis patients.
abstract: In order to evaluate hepatitis C virus-RNA (HCV-RNA), immunoglobulin M (IgM) anti-HCV and risk factors in haemodialysis patients, 180 subjects (45 HCV negative and 135 HCV positive) were studied. Sex, age, duration of dialysis, number of transfusions and ALT were also considered. HCV-RNA was determined by the Amplicor HCV test, and IgM anti-HCV by the Abbott HCV IgM EIA. These markers were present in 40% and 30.4% of anti-HCV positive subjects. The agreement between the two tests employed was 77%. The results showed a close association between HCV-RNA and IgM anti-HCV with abnormal ALT levels and between HCV-RNA and the number of transfusions. Both of these markers were different when correlated with age and time on dialysis, respectively. Therefore, IgM anti-HCV may also serve as a serological marker of HCV infection and a complementary marker of virus replication.
