    Abstract:
    To clarify the prevalence of Japanese children thought to be at a risk for infection with GB virus-C (GBV-C)/hepatitis G virus (HGV), we investigated the detection rates of serum GBV-C/ HGV ribonucleic acid (RNA) by reverse transcription-seminested PCR and serum anti-HGV-E2 antibody by ELISA in 162 children with histories of blood or plasma product transfusions or with liver diseases and performed phylogenetic analysis of the 5' noncoding region sequences of GBV-C/HGV genomes. Children with histories of transfusions were divided into those who had been treated with antineoplastic agents for malignant diseases (malignant group) and those who had received transfusions for nonmalignant diseases (nonmalignant group). Children with liver diseases were divided into hepatitis B (HBV), hepatitis C (HCV), and non-A-C hepatitis groups. We detected GBV-C/ HGV RNA in 11 of 33 (33.3%) and anti-HGV-E2 in 1 of 27 (3.7%) children in the malignant group and in 3 of 56 (5.4%) and 1 of 53 (1.9%) children, respectively, in the nonmalignant group. Neither GBV-C/HGV RNA nor anti-HGV-E2 was detected in the HBV and non-A-C hepatitis groups. GBV-C/HGV RNA and anti-HGV-E2 were detected in 7 of 23 (30.4%) and in 1 of 18 (5.6%) children, respectively, in the HCV group. All children positive for either GBV-C/HGV RNA or anti-HGV-E2, except one whose route of GBV-C/HGV infection suggested mother-to-infant transmission, had histories of transfusions. The phylogenetic analysis showed that all isolates in this study were divisible into three groups and that most of them were clustered into group 3 (Asian group).
