By using reverse transcriptase polymerase chain reaction (RT-PCR) assay, HCV-RNA and HGV-RNA in plasma and PBMCs of 72 patients with hepatitis C was detected. It was showed that HGV RNA was positive in plasma of 11 patients, in PBMCs of 15 patients, and simultaneously in both of plasma and PBMCs of 10 patients with the co-infection rate being 22.2 %. Nine patients were both HGV RNA and HCV RNA positive in plasma, 11 patients were both HGV RNA and HCV RNA positive in PBMC, and 6 patients were both HGV RNA and HCV RNA positive in both plasma and PBMC with the positive rate being 12.4 %,15.3 % and 8.3 % respectively. The positive rate of both HGV RNA and HCV RNA in PBMCs was higher than in plasma. It was concluded that the HGV co-infection rate in the patients with hepatitis C was 22.2 %. Simultaneous examination of plasma and PBMC can improve clinically detectable rate.展开更多

The overall positive rate was 23. 68 %; the positive rate in 1-10 time transfusion recipients (mean 3. 26 times) was 3. 70 % while in over 10 time transfusion recipients (mean 20. 09 times) was 72. 73 %. A statistically significant difference was found between the two groups (P<0. 001). All HGV positive children showed diminished immunity and most were single HGV infection with no clinical and biochemical evidences of acute hepatitis. Our results suggest that HGV is one of the main causes of post-transfusion hepatic virus infection and the prevalence is related to transfusion times. Hematological malignancy maybe the most susceptible confluence of HGV.展开更多
