本文报告1例非甲非乙型肝炎后发生再生障碍性贫血的病人。患者女生、21周岁,因一周来厌食不适和黄疸入院。病前无明显的感染史。血清丙氮酸转氨酶为39μkat/L,胆红素为260μM/L,碱性磷酸酶活性稍有增高(7.5μKat/I)。因持续的高血清转氨酶活性,发病后一个月作肝活检,有明显的炎症反应而无肝硬变迹象,与重型病毒性肝炎后期变化一致。RIA法测定血清中的抗HAV This article reports one patient who developed aplastic anemia after non-A, non-B hepatitis. Female patient, 21 years old, due to anorexia and jaundice admitted to hospital for one week. No obvious history of infection before the disease. Serum alanine aminotransferase 39μkat / L, bilirubin 260μM / L, alkaline phosphatase activity slightly increased (7.5μKat / I). Due to persistent high serum aminotransferase activity, a month after the onset of liver biopsy, a clear inflammatory response without signs of liver cirrhosis, consistent with late changes in severe viral hepatitis.
