CBV-C or hepatitis G virus (GBV-C/HGV) is a novel RNA virus with similarities to members of the Flaviviridae family, especially hepatitis C. Viral RNA is detected in about 1. 5% of American blood donors. with higher prevalence in multiply transfused patients and in individuals with hepatitis or liver disease.
Some cases of aplastic anaemia follow apparent non-A, non-13, non-C viral hepatitis, and CBV-C viraemia has been described in three case reports of hepatitis-associated aplastic anaemia.
We tested clinical samples from patients with aplastic anaemia with or without recent hepatitis for the presence of GBV-C/HGV Virus was detected in a total of 15/57 (26.3%) of patients with aplastic anaemia and 12/52 (23.1% of multiply transfused control patients.
Sequencing of the 188 base pair NS3 helicase PCR product in the serum of five individuals indicated the same high degree of sequence variation as has been seen among other isolates of the virus.
GBV-C/HGV does not appear to be implicated in the aetiology of aplastic anaemia.
