Hepatitis C virus (HCV) RNA among anti-HCV-positive blood donors and their recipients.
Seven of 24 blood donors positive in Ortho's first-generation antibody to hepatitis C virus (anti-HCV) test (EIA-1) were also positive in Ortho's second-generation test (EIA-2). All 7 had at least two anti-HCV positive recipients, whereas only 1 of the 17 EIA-2-negative donors had an anti-HCV-positive recipient. This recipient was a multitransfused patient with von Willebrand's disease. Five of the 7 EIA-2-positive donors had detectable HCV RNA. We traced and tested 38 of the still living blood recipients from the 7 EIA-2-positive donors. Twenty-eight of these were EIA-2 positive and 22 were HCV-PCR positive. One patient with Waldenstroem's hypergammaglobulinemia was EIA-2 negative but HCV-PCR positive. All the EIA-2-positive sera showed reactivity in Ortho's recombinant immunoblot assay (RIBA-2), but 5 of the 28 recipients and 1 of the donors reacted with only one band (RIBA-2 indeterminate). Among 32 recipients who probably had received EIA-2-positive blood, 29 (91%) had markers of an HCV infection. Twenty-two (75%) of the HCV-infected recipients had detectable HCV RNA more than 6 months after transfusion and hence were chronic HCV carriers.
