文题释义:
异基因造血干细胞移植:
是血液系统恶性疾病有效乃至唯一根治的手段,其供者来源可为无关供者、亲缘供者(包含同胞供者);根据放化疗强度,其预处理方案可分为清髓预处理、非清髓预处理、减低强度预处理;供受者血型不合不是移植禁忌,但可能会造成红系造血恢复延迟。
纯红细胞再生障碍性贫血:是多种原因引起的骨髓单纯红细胞系造血衰竭,严重贫血,网织红细胞和骨髓红系细胞比例减少或缺如,而粒细胞、巨核细胞生成并无异常。干细胞移植后网织红细胞数量<1%的时间超过60 d,粒系恢复,骨髓穿刺红系前体细胞缺失,则可诊断为移植后纯红细胞再生障碍性贫血,是干细胞移植的少见并发症之一,目前对其发生率、高危因素尚无定论,对其诊疗尚无规范指南。

 

摘要
背景:
异基因造血干细胞移植后纯红细胞再生障碍性贫血的发生导致患者红系造血恢复延迟、血型转换时间延长,从而产生一系列并发症。因此,应重视异基因造血干细胞移植后纯红细胞再生障碍性贫血预防和诊断后的治疗对策,以加快移植后红系植入。目前纯红细胞再生障碍性贫血的发生率、高危因素尚无定论,诊疗尚无规范指南。
目的:探讨异基因造血干细胞移植后纯红细胞再生障碍性贫血发病的高危因素和治疗对策。
方法:2例患者,诊断为急性白血病,接受同胞供者的清髓性外周血干细胞移植,供受者血型均为A供O,分别于+44 d、+58 d出现纯红细胞再生障碍性贫血,复习诊治过程和相关文献。
结果与结论:①1例经美罗华、大剂量甲强龙、血浆置换治疗后痊愈;另1例经大剂量甲强龙、美罗华和硼替佐米治疗后血象于5个月后逐渐恢复;②总结文献报道的93例发生移植后纯红细胞再生障碍性贫血病例,所有患者均为供受者ABO血型不合,明确血型的患者中A供O者占66%(47/71),同胞供者、非清髓预处理、病毒感染等是发生纯红细胞再生障碍性贫血的高危因素,主要治疗方法有血浆置换、激素、利妥昔单抗等;③异基因造血干细胞移植后纯红细胞再生障碍性贫血是少见的并发症,多种因素可促进其发生,目前尚无一致的治疗共识,部分患者可以自愈,对难治性患者,硼替佐米和艾曲波帕可作为新的靶向治疗药物。

Abstract:

BACKGROUND: The occurrence of pure red blood cell aplasia after allogeneic hematopoietic stem cell transplantation delays the recovery of erythroid hematopoiesis and prolongs the conversion time of blood type, eventually resulting in a series of complications. Therefore, attentions should be paid to the treatment and prevention of pure red blood cell aplasia after allogeneic hematopoietic stem cell transplantation to accelerate the erythroid implantation after transplantation. At present, the incidence and risk factors of pure red blood cell aplasia are inconclusive, and there is also no standard guide for the diagnosis and treatment.
OBJECTIVE: To explore the risk factors and treatments of pure red cell aplasia following allogeneic hematopoietic stem cell transplantation.
METHODS: Two patients with acute leukemia, who had received allogeneic hematopoietic stem cell transplantation with nonmyeloablative conditioning from sibling donor, were enrolled. The blood types of the patients and the donors were O positive and A positive, respectively. The two patients developed pure red cell aplasia at day +44 and day +58, respectively. Here, we reviewed the diagnosis and treatment process with literature.
RESULTS AND CONCLUSION: One patient recovered by the treatment with rituximab, high-dose methylprednisolone, and plasma exchange. The other patient benefited from the treatment with high-dose methylprednisolone, rituximab, and bortezomib, and the patient’s blood routine parameters recovered gradually after 5 months. (2) As previously reported in 93 cases of pure red blood cell aplasia after allogeneic hematopoietic stem cell transplantation, 66% (47/71) of the patients with determined blood type were O positive and the donors were A positive. The risk factors for pure red blood cell aplasia after allogeneic hematopoietic stem cell transplantation include sibling donor, nonmyeloablative conditioning, and virus infection; and the major treatment includes plasma exchange, steroid, and rituximab. Overall, pure red cell aplasia is a rare complication of allogeneic hematopoietic stem cell transplantation, and multiple factors can facilitate its occurrence. A consensus on the treatment of pure red cell aplasia has not been reached. Some patients can recover by themselves, and bortezomib and eltrombopag as new targeted drugs may be effective for refractory pure red cell aplasia.
