目的：了解血液病患者输血后的庚型肝炎病毒（ＨＧＶ）感染情况。方法：对６３例血液病患者采用ＲＴＰＣＲ方法检测ＨＧＶＲＮＡ、丙型肝炎病毒（ＨＣＶ）ＲＮＡ，应用ＥＬＩＳＡ方法检测抗ＨＧＶ、ＨＢｓＡｇ。结果：ＨＧＶＲＮＡ阳性率为７．９％，抗ＨＧＶ阳性率６．３％；ＨＣＶＲＮＡ阳性率为４６．０％。ＨＧＶ感染通常伴有ＨＣＶ感染及丙氨酸转氨酶升高。ＨＧＶ感染与输血量有关，与血液病种类无关。结论：血液病输血可引起ＨＣＶ、ＨＧＶ的传播 Objective: To understand the infection of Hepatitis G virus (HGV) after blood transfusions in patients with blood diseases. Methods: HGV RNA and hepatitis C virus (HCV) RNA were detected by RTPCR in 63 patients with hematological diseases. AntiHGV and HBsAg were detected by ELISA. Results: The positive rate of HGV RNA was 7.9%, the positive rate of anti-HGV was 6.3%, and the positive rate of HCVRNA was 46.0%. HGV infection is usually accompanied by HCV infection and elevated alanine aminotransferases. HGV infection and blood transfusion, has nothing to do with the type of blood disease. Conclusion: Blood transfusion can cause the spread of HCV and HGV
