氨磷汀联合重组人红细胞生成素治疗高龄骨髓增生异常综合征近期疗效观察

本研究的目的是观察氨磷汀(amifostine，AMF)联合红细胞生成素(EPO)治疗高龄骨髓增生异常综合征(MDS)患者的近期疗效。治疗的2例高龄MDS患者中1例为MDS-RA患者(9l岁)，另1例为MDS—RCMD患者(86岁)。治疗方案为rh—EPO6000u皮下注射，1周3次；AMF0．4g静脉滴注，每周连续5天，休息2天，连用4周。结果表明：4周后2例患者均显示出很好的近期疗效，其中MDS—RA患者输血时间间隔均较治疗前有的延长。1例MDS-RA患者的网织红细胞在治疗开始后第1周即恢复正常，并一直保持在正常水平；另1例MDS-RCMD患者治疗后血像三系细胞量均明显上升，异常增高的网织红细胞数量呈下降趋势。结论：AMF联合rh-EPO在治疗高龄MDS患者可能有良好的应用前景，但其临床远期疗效还有待于进一步研究。

Short-Term Curative Effect of Amifostine Combined with rhEPO on Aged Patients wilh Myelodysplastic Syndrome

The aim of this study was to investigate the curative effect of amifostine (AMF) combined with recombinant human erythropoietin (rhEPO) on the aged patients with myelodysplastic syndrome. Two aged MDS patients (one aged 91; another 86) were treated with amifostine and rhEPO over a period of 4 weeks. The results showed that a short-term curative effect was observed and transfusion interval was prolonged in both patients after 4 week treatment with 5 x 0.4 g AMF plus 3 x 6,000 U rhEPO per week. The reticulocyte count in MDS-RA patient returned to normal at first week of treatment and still remained in normal level for 4 weeks; leukocyte, hemoglobin and platelet values in peripheral blood of MDS-RCMD patient obviousby increased, the abnormally increased reticulocyte value displayed a decrease trend after amifostine plus rh-EPO treatment. In conclusion, amifostine plus rhEPO may have a good therapeutic effect for aged MDS patients, and its clinical long-term curative effect still needs further evaluation.
