作者报道22例同输血有关的肝炎,其致病因子并非甲型或乙型肝炎病毒。作者认为,似乎至少有一小部分肝炎抗原阴性的输血后肝炎是由尚未被识别的其他传染性因子所引起。22例肝炎患者均系接受心脏手术,曾输血11～32单位(平均16.7单位),潜伏期自2～15周(平均7.3周)不等,病程2周～6 The authors report 22 cases of hepatitis associated with blood transfusions, the pathogenic factor is not the A or hepatitis B virus. The authors believe that it seems that at least a small proportion of hepatitis B virus-negative post-transhepatic hepatitis is caused by other infectious agents that have not yet been identified. Twenty-two patients with hepatic disease underwent cardiac surgery. Transfusion of blood from 11 to 32 units (mean, 16.7 units) was performed. The incubation period ranged from 2 to 15 weeks (mean, 7.3 weeks). The course of disease ranged from 2 weeks to 6
