骨髓瘤肾病患者自体外周血干细胞移植治疗临床分析

目的:探讨骨髓瘤肾脏累及患者进行自体外周血干细胞移植(APBSCT)治疗的疗效和安全性。方法:首诊为多发性骨髓瘤(MM)肾病的男性患者4例,年龄35~53岁,进行常规血生化,血、尿免疫蛋白电泳和骨髓穿刺检查,3例行肾脏活组织检查(活检),常规化学治疗(化疗)后均行大剂量化疗(HDT)联合APBSCT。结果:4例患者中IgG型2例,IgD及无分泌型各1例;ⅡA期2例,ⅢA期1例,ⅢB期1例;确诊时均有蛋白尿(1.51～5.70 g),急性肾损伤(AKI)2例,慢性肾脏病(CKD)Ⅱ期、CKDⅤ期各1例。肾穿刺3例中1例弥漫间质炎细胞浸润,1例为轻链沉淀肾病(LCDD),另1例为管型肾病;1例未肾活检,临床推测MM管型肾病可能。移植前常规化疗4~6疗程。3例轻、中度肾功能受累者APBSCT治疗后1例再次发生AKI,但短时间恢复,长期随访尿蛋白基本转阴性,肾功能稳定无进展;1例移植后1年转变为浆细胞白血病死亡,2例MM完全缓解(CR)。1例严重肾功能受累(CKDⅤ期)者移植后因感染性休克死亡。结论:HDT联合APBSCT是治疗MM的有效方法。APBSCT治疗对轻、中度肾功能受累MM肾病患者的肾功能无明显影响,疗效满意。严重肾功能衰竭患者中进行该治疗尚需进一步探讨。

Autologous peripheral blood stem cell transplantation in multiple myeloma patients with renal involvement

Objective To study the efficacy and safety of autologous peripheral blood stem cells transplantation(APBSCT)therapy for multiple myeloma(MM) patients with renal involvement.Methods Four male patients,aged 35 to 53 years,diagnosed as MM with renal involvement were enrolled.All patients had undergone routine biochemical test,blood and urine immunoelectrophoresis,and bone marrow biopsy,and renal biopsy were performed in three of them.All of them received high-dose chemotherapy(HDT) with APBSCT after 4-6 cycles...
