title: [Detection of GBV-C/HGV infection in patients with liver diseases].
abstract: The aim of this article is to study the prevalence of GBV-C/HGV in patients with liver diseases and the clinical features in patients with (GBV-C/HGV infection. The serum samples were obtained from 169 patients with liver diseases in You An Hospital). Serum GBV-C/HGV RNA was detected by reverse transcription nested polymerase chain reaction (RT-nPCR) using two primer pairs of 5' untranslated region (5' UTR) of HGV. Serum anti-HGV was detected by ELISA simultaneously. The partial GBV-C/HGV genome isolated from one patient was cloned into T vectors and sequenced by dideoxy-mediated chain termination methods. Among 169 patients with various liver diseases, the GBV-C/HGV RNA positive rate was 9.5% (16/169), including 11.1% (1/9) of AHA, 4.1% (3/73) of CHB, 16.2% (6/37) of CHC, 13.3% (2/15) of AH(nonA-E) 12.5% (1/8) of CH(nonA-E) 15.4% (2/13) of LC and 33.3% (1/3) of SH cases. Of 29 patients having a history of surgical operation and transfusion, 9(31.0%) was positive for GBV-C/HGV RNA, which was remarkably higher than those cases without surgical operation and transfusion. The sequence analysis showed that there was 89.14%-98.91% nucleotide identity between our isolate and published GBV-C/HGV isolates. The results also suggested that infection rate of GBV-C/HGV was around 9.5% in patients from Beijing region, patients with GBV-C/HGV infection might show various clinical features and GBV-C/HGV might not be the major cause of hepatitis nonA-E.
