一种新发现的DNA病毒——输血传播病毒(TTV)已证实与输血后肝炎的病因有关。作者就英国供血员中TTV病毒血症的发生率和血制品受TTV污染的程度进行了调查。同时,还对TTV在原因不明的暴发型肝衰竭(FHF)中致病的可能性作了研究。 从供血员和FHF患者的血浆及血制品(凝血因子Ⅷ见和Ⅸ的浓缩物、免疫球蛋白)中 A newly discovered DNA virus, the transfusion transmitted virus (TTV), has been shown to be involved in the etiology of post-transfusion hepatitis. The authors investigated the incidence of TTV viremia in British blood donors and the extent to which blood products were contaminated with TTV. At the same time, the possibility of TTV in the pathogenesis of unexplained fulminant hepatic failure (FHF) was also studied. From plasma and blood products of blood donors and FHF patients (coagulation factor VIII and IX concentrates, immunoglobulins)
