摘要
对４２例符合急性再生障碍性贫血（ＡＡＡ）诊断的苯中毒患者，采用ＳＳＬ方案治疗。按疗效将其分为ＡＡＡ－ａ组（６例）和ＡＡＡ－ｂ组（３６例），并与８例原发性ＡＡＡ和５０例原发性慢性再生障碍性贫血（ＣＡＡ）相比较。结果苯中毒ＡＡＡ－ａ组患者的骨髓增生度、有核细胞分裂指数、原始＋早幼粒细胞、原始＋早幼红细胞等反映骨髓造血功能的指标与原发性ＡＡＡ组相似（Ｐ＞０．０５），采用ＳＳＬ方案治疗无效，均在６个月内死亡；苯中毒ＡＡＡ－ｂ组上述反映骨髓造血功能指标明显高于原发性ＡＡＡ组及苯中毒ＡＡＡ－ａ组（Ｐ均＜０．０１），采用ＳＳＬ方案治疗均有效，缓解率达８８．９％。认为ＡＡＡ－ａ组应归入ＡＡＡ，而ＡＡＡ－ｂ组近似于ＣＡＡ中的ＳＡＡ－ＩＩ型。两组苯中毒致再生障碍性贫血患者骨髓造血功能和对ＳＳＬ方案治疗结果的不同，当属量的差异还是质的不同，值得进一步研究。作者根据骨髓造血的一些指标设计了分级记分分类法，ＳＡＡ－ＩＩ型积分均≥４分，ＡＡＡ积分均≤３分，认为该分类法可作为两者鉴别的一种手段。
orty-two cases of benzolism diagnosed as acuteaplastic anemia(AAA) were divided into two groupsaccording to their responses to androgen therapy:6 cas-es of group a and 36 of group b. Bone marrowhemopoietic indices(including cellularity division indexof nucleated cells, myeloblasts + promyelocytes,proerythroblasts + proerythrocytes ) of group a weresimilar to that of primary AAA(P>0. 05). All casesin this group showed no response to SSL regimen ther-apy and died within 6 months.However , bone marrowhemopoietic indices of group b were significantly betterthan those of primary AAA and group a(P< 0. 01 ),and all cases in this group showed good response toSSL regimen therapy with a complete remission rate of88.9%. It suggested that the group a was part ofAAA and the group b of severe aplastic anemia type IIof chronic AA.
