文题释义:
造血干细胞移植后感染:
移植后患者早期死亡主要因素之一。单倍体移植由于免疫抑制强,细胞免疫重建延迟,发生严重感染风险可能会增加,混合感染可能性大,且感染不易控制。
移植物抗宿主反应:是一种特异的免疫现象,是移植物组织中的免疫活性细胞与免疫受抑制的、组织不相融性抗原受者的组织之间的反应。因此,移植物抗宿主病的发生必须具备以下条件:①移植物必须具有免疫活性的淋巴细胞;②宿主必须含有移植物中所没有的组织相容性抗原;③宿主必须无力对移植物发动一个有效的免疫攻势。

 

摘要
背景:
异基因造血干细胞移植是根治白血病的有效方法之一。单倍体相合造血干细胞移植为无HLA相合供者的患者提供一种重要选择。
目的:探讨单倍体造血干细胞移植治疗白血病的临床疗效及并发症。
方法:选择2007年11月至2015年3月行单倍体异基因造血干细胞移植的患者23例,其中急性淋巴细胞白血病4例,急性髓系白血病12例,慢性粒细胞白血病7例。预处理方案Ⅰ:环己亚硝脲+阿糖胞苷+白消安+环磷酰胺;预处理方案Ⅱ:环磷酰胺+全身照射;预处理方案Ⅲ:氟达拉滨+阿糖胞苷+白消安+环磷酰胺;预处理方案Ⅳ:白消安+环磷酰胺。给予抗胸腺细胞球蛋白、环孢素A、吗替麦考酚酯及短程甲氨蝶呤预防移植物抗宿主病。移植后观察受者的造血重建、并发症以及预后情况。
结果与结论:①22例获粒系重建,19例获巨核系重建;②急性移植物抗宿主病7例,慢性移植物抗宿主病4例;③移植后100 d内移植相关死亡率22%(5/23),分别死于植入失败、脑出血、感染、急性移植物抗宿主病;④移植后100 d至2年内无病生存14例,2例死亡,分别死于移植物抗宿主病及真菌感染、疾病复发及慢性移植物抗宿主病,2例复发后仍在治疗中;⑤结果表明,单倍体造血干细胞移植是白血病患者一种有效的治疗方案,值得进一步研究及总结。

Abstract:

BACKGROUND: Allogeneic hematopoietic stem cell transplantation (HSCT) is one of the effective methods in the treatment of leukemia. The haploidentical HSCT is an option for the patients who need a HSCT without a human leukocyte antigen (HLA)-matched donor.
OBJECTIVE: To study the clinical efficacy of HLA-haploidentical HSCT on leukemia and its complications.
METHODS: A total of 23 patients (4 cases of acute lymphoblastic leukemia, 12 of acute myelogenous leukemia, and 7 of chronic granulocytic leukemia) who had been treated with HLA-haploidentical HSCT from November 2007 to March 2015 were enrolled. Conditioning regimen I was set as cyclohexyl nitrosourea+cytarabine+busulfan+cyclophosphamide; regimen II as cyclophosphamide+total body irradiation; regimen III as fludarabine+cytarabine+busulfan+cyclophosphamide; and regimen IV as busulfan+cyclophosphamide. Cyclosporin A, mycophenlate mofetil, antithymocyte globulin and methotrexate were used to prevent graft-versus-host disease (GVHD). Hematopoietic remodeling, complications and prognosis were observed in all patients undergoing HLA-haploidentical HSCT.
RESULTS AND CONCLUSION: Of the 23 patients, 22 achieved reconstitution of the granulocyte series, and 19 achieved reconstruction of the megakaryocyte series. Additionally, there were 7 cases of acute GVHD and 4 of chronic GVHD. Transplant-related mortality was 22% (5/23) within 100 days post transplantation including graft failure, acute GVHD, intracranial hemorrhage and disseminated infections. There were 14 cases of disease-free survival from 100 days to 24 months post transplantation, 2 cases of death due to GVHD and fungal infection, or recurrence and chronic GVHD, and 2 cases of recurrence under treatment. These findings indicate that HLA-haploidentical HSCT is an effective approach for the treatment of patients with leukemia, which is worth further investigation in clinical practice.
