摘要: [目的] 了解泉州地区各型肝炎患者TTV感染情况。[方法] 设计特异性引物采用巢式PCR方法对57例肝炎患者及20例健康献血员的血清标本进行TTVDNA检测。[结果] 肝炎患者TTVDNA阳性率为15.8%,其中乙型肝炎(或重叠丁型肝炎)患者TTVDNA阳性率为25.0%(6/24),非A-G型肝炎患者TTVDNA阳性率为13.64%(3/22),甲、戊型肝炎患者未检出;健康献血员为35.0%。TTVDNA阳性的9例肝炎患者中3例有受血史,单纯TTV感染3例治愈,TTV、HBV/HDV重叠感染6例,治愈好转5例。[结论] 本研究证实泉州地区存在TTV感染。TTV感染可经血传播,其致病性较弱,对TTV感染的流行病学及临床意义有待进一步研究。 关键词:TT病毒;巢式PCR;流行病学;肝炎;致病性 中图分类号: R 512.603 文献标识码: A 文章编号:1007-2705(2000)02-0006-02

Abstract: [Objective] To investigate the infection status of transfusion transmitted virus (TTV) infection among hepatitis patients in Quanzhou area. [Methods] TTVDNA from sera of 57 hepatitis patients and 20 blood donors were detected by nested polymerase chain reaction (nested-PCR) with specific primers. [Results] TTVDNA was detected in sera from 9 hepatitis patients among 6 patients with HVB + HDV, 3 with non A-G and 7 blood donors. Among 9 TTV infected hepatitis patients, 3 patients were associated with history of recipient blood products, 3 patients with simple TTV infection, and 5 patients of 6 with HBV/HDV and TTV co-infection were recovery. [Conclusion] There is TTV infection in Quanzhou area. TTV infection can be transmitted by blood but the pathogenicity is mild. Further study should be done to explore its epidemiology and clinical significance. Key words:TT virus; nested-PCR; epidemiology; hepatitis;pathogenicity
近年来,人们注意到除HAV、HBV、HCV、HDV、HEV和HGV等肝炎病毒外,仍有5%~10%的肝炎患者不能确定原因[1]。1997年底Nishizawa等[2]使用代表性差异分析法(RDA)首次从1例非A-G型的输血后肝炎患者血清中分离到一种新的单链DNA病毒基因,暂命名为输血传播病毒(transfusion transmitted virus, TTV)。 我们根据公布的TTV序列,设计了两对特异性引物,建立了检测血清TTVDNA的巢式PCR方法[3],对泉州地区各类型肝炎患者TTV感染状况进行调查,报道如下。
