治疗前铁过载对急性重型再生障碍性贫血免疫抑制治疗血液学反应的影响
目的研究重型再生障碍性贫血(SAA)患者免疫抑制治疗(IST)前铁过载对IST疗效的影响。方法回顾性分析2003年2月至2011年12月行IST的SAA患者共257例,研究治疗前影响铁过载的相关因素及铁过载对IST疗效影响。结果257例患者中位血清铁蛋白(SF)387(6-2004)gg/L,218例(84.8%)SF高于正常参考值;36例(14.0%)SF〉1000μg/L,诊断为铁过载,其中SAA20例,极重型AA(VSAA)16例。单因素分析显示年龄〉14岁(P=0.010)、输血量(成人/〉4U,P=0.007;儿童≥0.06U/kg,P=0.024)为铁过载的影响因素。多因素分析显示...

Summary: | 目的研究重型再生障碍性贫血(SAA)患者免疫抑制治疗(IST)前铁过载对IST疗效的影响。方法回顾性分析2003年2月至2011年12月行IST的SAA患者共257例,研究治疗前影响铁过载的相关因素及铁过载对IST疗效影响。结果257例患者中位血清铁蛋白(SF)387(6-2004)gg/L,218例(84.8%)SF高于正常参考值;36例(14.0%)SF〉1000μg/L,诊断为铁过载,其中SAA20例,极重型AA(VSAA)16例。单因素分析显示年龄〉14岁(P=0.010)、输血量(成人/〉4U,P=0.007;儿童≥0.06U/kg,P=0.024)为铁过载的影响因素。多因素分析显示输血量为影响铁过载的预后因素[P=0.001,OR=0.218(95%CI0.092~0.520)]。在SAA组患者中,铁过载患者IST后6个月血液学反应率低于非铁过载患者(55.0%对77.5%,P=0.037)。而VSAA组差异无统计学意义(P=0.424)。单因素分析示网织红细胞绝对值(ARC)(P=0.014)及铁过载(PtO.037)与IST后6个月疗效相关。多因素分析示铁过载[P=0.021,OR=4.092(95%CI1.235~13.563)]、ARC≥20×10^9/L[P=0.040,OR=2.743(95%CI1.049-7.175)]为影响IST6个月血液学反应的预后因素。结论IST前84.8%的SAA/VSAA患者SF水平升高,14.0%达铁过载水平;年龄〉14岁及输血量增多(成人≥4U,儿童≥0.06U/kg)患者IST前更易发生铁过载;治疗前铁过载为影响SAA患者IST的预后不良因素。 |

Methods 257 SAA/VSAA patients who underwent first-line IST from Feb, 2003 to Dec, 2011 in Anemia Therapeutic Centre, Institute of Hematology and Blood Diseases Hospital were retrospectively analyzed, the status of SF before IST and the IO-affected factors were studied. The effects of IO on hematologic response of SAA/VSAA patients were evaluated as well. Results The median level of SF of 257 patients was 387 (6-2 004) μg/L. 36 patients (14%) had IO, including 20 SAA and 16 VSAA patients. According to univariate logistical regression analyses, IO was influenced by age〉1 |
