病毒性肝炎(以下简称肝炎)常有如贫血、白细胞减少症、非典型淋巴细胞增多症、血小板减少症等血液学变化;至于暂时性全血细胞减少症、再生障碍性贫血(以下简称再障)等则极罕见。但近年来肝炎后再障的报告渐多,简介如下: 一、发病情况:1955年Lorenz和Quaiser报告第一例肝炎并发再障,此后报告渐多,至今已有200余例。性别和年龄:与肝炎病例相似,男高于女,约为1.4～2∶1,个别报告为4∶1。发病年龄自6个月至74岁不等,平均18～20岁,以11～20岁者居多(约占40～50％);10岁以下和21～30岁者次之,近3/4患者在20岁以下,随年龄的增长发病渐减。与一般再障不同,后者小于20岁者占少数,仅为1/3～1/4。
Viral hepatitis (hereinafter referred to as hepatitis) often have anemia, leukopenia, atypical lymphocytosis, thrombocytopenia and other hematological changes; As for the temporary pancytopenia, aplastic anemia (hereinafter referred to as aplastic anemia), etc. It is extremely rare. However, in recent years, there have been more reports of aplastic anemia after hepatitis. The brief introduction is as follows: First, the incidence: In 1955, Lorenz and Quaiser reported the first case of hepatitis complicated with aplastic anemia. Since then, more reports have been reported, and more than 200 cases have been reported so far. Sex and age: Similar to the hepatitis cases, males are taller than females, about 1.4 to 2: 1, and individual reports are 4: 1. The age of onset ranged from 6 months to 74 years old, with an average of 18-20 years old, mostly from 11 to 20 years old (about 40 to 50%); those under 10 and 21-30 years old were nearly 3/4 Patients under the age of 20, with the onset of age decreased. And general aplastic anences, the latter less than 20 years of age accounted for a minority, only 1/3 to 1/4.
