丙型肝炎病毒抗体(抗-HCV)不仅见于大多数输血后非甲非乙型肝炎的成人患者,而且也见于许多不明原因的急性或慢性非甲非乙型肝炎患者。作者用第二代ELISA观察了一组年龄为2～14岁的无全身基础疾病的急性或慢性病毒性肝炎38例。在作前瞻性研究或纵向研究时这些患儿已恢复。所有病例分成5组:(1)已恢复的急性非甲非乙型肝炎5例,其中1例在恢复以前4个月曾输血2单位,而其余4例无明显的经皮传播史。(2)慢 Hepatitis C virus antibodies (anti-HCV) are found not only in the majority of adult patients with post-transfusion non-A, non-B hepatitis, but also in many unexplained acute or chronic non-A non-B hepatitis patients. The authors used a second-generation ELISA to observe a group of 38 patients aged 2-14 years with acute or chronic viral hepatitis without systemic underlying disease. These children have been recovered in a prospective or longitudinal study. All cases were divided into five groups: (1) 5 cases of recovered non-A, non-B hepatitis were recovered, of which 1 had transfusion of 2 units 4 months prior to recovery and the other 4 had no history of transdermal transmission. (2) slow
