全反式维甲酸联合亚砷酸诱导治疗急性早幼粒细胞白血病凝血及纤溶指标改变的初步研究

目的探讨全反式维甲酸（ATRA）联合亚砷酸（As2O3）诱导治疗急性早幼粒细胞白血病（APL）凝血及纤溶指标的变化。方法治疗组18例，采用ATRA 20～30mg／d，分3次口服，直至完全缓解，0．1％As2O3 10ml加入5％葡萄糖注射液500ml静脉滴注，1次／d，连续28d。对照组10例，单用ATRA 45～60mg／d，分3次口服，直至完全缓解。结果治疗组CR17例，对照组CR8例，治疗组CR率高于对照组（P〈0.05）；对照组出现不同程度的口干、维甲酸综合征等，有2例被迫停药，治疗组上述反应轻，出现肝功能损害，需加强保肝治疗；治疗组纤维蛋白原含量（Fbg）、D-二聚体（D—dimer）恢复时间分别为7、21d，对照组Fbg、D—dimer恢复时间分别为14、28d。结论ATRA联合As2O3诱导治疗APL CR率高，副作用小，凝血、纤溶指标恢复快，D—dimer作为早期诊断及观察治疗变化意义重大。

A primary study on the indexes change of coagulation and fibrinolysis in APL with ATRA and As2O3

Objective To explore the indexes change of coagulation and fibrinolysis in APL with ATRA and As2O3.Methods Treatment group 18 eases were undeaaked ATRA 20-30 mg/d until relieved completely.0.1%arsenic trioxide 10 ml with 5%glucose 500 ml for 28 days.Normal control 10 cases were undertaked ATRA 45～60 mg/d until relieved completely.Results The CR rate of treatment group was higher than control group(P＜0.05),the patients of control group showed different reactions such as thirsty mouth,rationale acid syndrome.2 cases reacted strongly and the treatment had to be interrupted,the patients of treatment group had little reaction,but liver function were badly hurt and liver-protection treatment was needed.Fbg,D-dimer recovery time is 7 days,21 days in treatment group,14 days,21 days in control group.Conclusion CR rate is high and has little side effect,and indexes change of coagulation and fibrinolysis were recovered quickly,it has great significance to take D-dimer as early diagnose and observe the indexes change during the treatment.
