摘要:

目的 分析造血干细胞移植(HSCT)后移植相关血栓性微血管病(TA-TMA)患者的临床特征。方法 选取行HSCT的患者185例,确诊11例TA-TMA患者,作为病例组。从185例患者中随机选取30例年龄、移植方式、人类白细胞抗原配型相合的非TA-TMA患者,作为对照组。比较2组破碎红细胞比例,并分析11例TA-TMA患者的实验室指标结果及临床特征。结果 在185例行HSCT的患者中,确诊11例(5.9%,11/185)TA-TMA患者,年龄33(7~45) 岁,移植后发病时间76(22~152) d。病例组破碎红细胞比例为3.3%,高于对照组(0.4%)(P<0.05)。11例TA-TMA患者血红蛋白(Hb)水平、血小板(PLT)计数呈进行性降低、减少。乳酸脱氢酶(LDH)、血清肌酐(Cr)、血清总胆红素(TB)、C反应蛋白(CRP)、降钙素原(PCT)、环孢素A(CsA)水平均升高。8例伴有急、慢性移植物抗宿主病(GVHD),6例患者24 h尿蛋白阳性。除1例患者未检出病毒DNA之外,其他患者均伴有1种及以上病毒血症,至随访结束仅4例存活。结论 TA-TMA是骨髓移植后极为严重的一种并发症,患者如果合并GVHD,则预后较差,综合多项实验室指标结果有利于TA-TMA的早期诊断、治疗,降低死亡率。

Abstract:

Objective To analyze the clinical characteristics of transplantation-associated thrombotic microangiopathy (TA-TMA) after hematopoietic stem cell transplantation (HSCT). Methods A total of 185 patients undergoing HSCT were enrolled. Totally,11 cases were confirmed as TA-TMA (case group),and 30 non-TA-TMA cases with similar age,transplantation ways and human leukocyte antigen matching donor were enrolled as control group. The ratios of broken red blood cells in peripheral blood between the 2 groups were compared,and the laboratory indicators and clinical characteristics of 11 cases of TA-TMA were analyzed. Results Of the 185 patients undergoing HSCT,11 cases (5.9%,11/185) were TA-TMA. The age was 33(7-45) years old,and the onset time after transplantation was 76(22-152) d. The ratio of broken red blood cells in case group was 3.3%,which was higher than that in control group (0.4%)(P<0.05). In the 11 cases of TA-TMA,hemoglobin (Hb) level and platelet (PLT)count decreased progressively,and lactate dehydrogenase (LDH),serum creatinine(Cr),serum total bilirubin(TB),C-reactive protein(CRP),procalcitonin (PCT) and cyclosporin A (CsA) were at high levels. There were 8 cases with acute and chronic graft-versus-host diseases(GVHD) and 6 cases with positive 24 h urinary protein. Except 1 case was not detected for virus DNA,and the other cases were associated with more than 1 type of virus disease. Only 4 cases were alive until the end of follow-up period. Conclusions TA-TMA is an extremely serious complication after bone marrow transplantation. The prognosis is poor,when GVHD is combined. The determinations of a number of early laboratory indicators are necessary for the early diagnosis and treatment of TA-TMA to decrease mortality.
