摘要 目的 探讨非清髓性、骨髓和外周血造血干细胞移植治疗高风险重型再生障碍性贫血 (SAA)及移植后供者干细胞输注 (DSI)的疗效和并发症。方法 移植治疗 3例高风险SAA。预处理 :抗淋巴细胞球蛋白 (ALG)联合环磷酰胺 (CTX) ,CTX总量为 60~ 12 0mg/kg ,ALG为 12 0mg/kg。移植物抗宿主病 (GVHD)的预防 :环孢素A(CSA)联合甲氨蝶呤 (MTX)或甲基强的松龙 (MP) ,CSA和MP分别用至 6个月和 2个月逐渐减量并停药。供者外周血造血干细胞 (PBSC)动员 :G -CSF 5 μg/ (kg·d)× 5d。移植细胞数分别为MNC :7 2 4× 10 8/kg ,6 0 0× 10 8/kg ,6 66× 10 8/kg ;CD3 4+ 细胞 :4 2 6×10 6/kg ,8 95× 10 6/kg ,4 66× 10 6/kg。移植后形成混合性嵌合体 (MC)者 ,进行DSI。结果 移植后 3例白细胞最低值 :0 2 6× 10 9/L ,0 5 0× 10 9/L ,0 10× 10 9/L ,中性粒细胞 >0 5× 10 9/L和血小板 >2 0× 10 9/L时间分别为移植后第 12 ,3 ,15天和 0 ,5 ,10天。 3例均获得造血细胞成功植入。 1例形成供者完全嵌合体 (CC)并长期维持造血。 2例MC者 ,1例出现排斥 ,1例巨核细胞植入不良 ,均经DSI ,造血均有恢复。 3例分别存活 10 ,6,3 4个月。结论 非清髓性骨髓联合外周血高剂量造血干细胞移植治疗高风险的SAA ,增加植入率。
