再生障碍性贫血(再障)是因骨髓造血功能衰竭引起全血细胞减少的一组综合征。近年来,再障与某些疾病的关系已逐渐被重视,并且相互影响转归,有必要加以介绍。一、再障与阵发性睡眠性血红蛋白尿(PNH) 再障与PNH同属造血干细胞疾病,两者关系十分密切。它们不仅在临床表现、血象和骨髓象有时有相似之处,个别可以相互转变或共存。约有1/4的PNH呈再障表现,约有1/2的PNH在病程中曾表现有骨髓增生低下,再障患者有5～15％的红细胞有
Aplastic anemia (aplastic anemia) is a syndrome of pancytopenia caused by hematopoietic depletion of bone marrow. In recent years, the relationship between aplastic anemia and certain diseases has gradually been taken seriously, and mutual influence and outcome, it is necessary to be introduced. First, aplastic anemia and paroxysmal nocturnal hemoglobinuria (PNH) aplastic anemia and PNH belong to hematopoietic stem cell disease, the relationship between the two is very close. They not only in clinical manifestations, blood and bone marrow sometimes have similarities, individual can change each other or co-exist. About a quarter of the PNH showed aplastic anemia, about 1/2 of the PNH showed low myeloproliferation in the course of the disease, and aplastic anemia in 5-15% of the erythrocytes
