再生障碍性贫血(再障)患者的预后与发病之初造血功能障碍的程度有密切关系。作者报道了日本的190例再障,其中男性91例、女性99例;年龄5～91岁,平均43.5岁。其中继发性或疑为继发性再障者43例,肝炎后再障3例,原发性144例。已死亡者111例,存活79例。后者已存活5年以上。判定再障严重程度的计分方法是:末梢血网织红细胞计数≥1万/mm~3为1分、中性粒细胞≥500/mm~3 The prognosis of patients with aplastic anemia (aplastic anemia) is closely related to the degree of hematopoietic disorder at the onset of aplastic anemia. The authors report on 190 cases of aplastic anemia in Japan, including 91 males and 99 females; aged 5 to 91 years, mean 43.5 years. Of which 43 cases of secondary or suspected secondary aplastic anemia, 3 cases of aplastic anemia, primary 144 cases. 111 cases have died, 79 cases of survival. The latter has survived more than 5 years. To determine the severity of aplastic anemia score method is: peripheral blood reticulocyte count ≥ 10000 / mm ~ 3 for 1 minute, neutrophils ≥ 500 / mm ~ 3
