  1. Hepatitis GBV-C sequences in patients infected with HCV contaminated anti-D immunoglobulin and among i.v. drug users in Germany.

    Article - En anglais


    A novel virus, GB virus-C (GBV-C), with a genome organization similar to those of the Flaviviridae family was identified in sera of patients diagnosed with hepatitis.

    Up to now little has been known about the prevalence of GBV-C sequences in German hepatitis C virus infected patients.


    We investigated two groups of patients chronically infected with hepatitis C virus : (i) Women infected in 1978/79 with HCV-contaminated anti-D immunoglobulin batches in former Eastern Germany, and (ii) I.v. drug users infected with different HCV subtypes.

    Nested polymerase chain reaction products amplified with GBV-C specific primer pairs within the helicase region were sequenced directly and compared with the GBV-C sequences reported recently.


    GBV-C sequences of the putative NS 3 gene region were shown to occur in two randomly selected anti-D immunoglobulin batches of 1978 (GI and GII) and two sera of HCV-infected women drawn in 1979.

    In patient 3, the HCV-infected erythrocyte donor in 1978, specific GBV-C sequences were also evident in serum drawn in 1990.

    In the high-risk group of i.v. drug users, 49% were GBV-C RNA positive.

    Among the 21 GBV-C positive samples, 11 were coinfected with HCV subtype 3a and 10 with subtype 1 b. All isolates showed an overall homology to the GBV-C sequence reported by Simons of 75-81% at the nucleotide level and 94-100% at the amino acid level. (...)
