摘　　要：目的:研究甲基泼尼松龙(MP)分层治疗非血缘脐血造血干细胞移植(UCBT)患者植入前综合征(PES)的疗效及对UCBT结果的影响。方法:回顾性分析自2012年11月至2015年3月于本中心接受UCBT的8例恶性血液病患者,其中单份UCBT7例,双份UCBT1例;急性髄系白血病4例,急性淋巴细胞白血病4例。所有患者均采用强化清髓方案行移植前预处理,其中采用分次全身照射(sTBI)7例,非sTBI1例。PES采用MP分层治疗,预防移植物抗宿主病(GVHD)方案均采用环孢素A(CsA)联合短程霉酚酸酯(MMF),随访截止日期为2016年8月31日。结果:8例UCBT患者移植早期均发生PES,PES累积发生率为100%。发生PES时C反应蛋白(CRP)峰值明显高于预处理阶段、PES控制后及发生Ⅱ~Ⅳ度急性GVHD(aGVHD)时的CRP水平(P<0.05),接受MP0.5mg·kg^(-1)·d^(-1)及MP1mg·kg^(-1)·d^(-1)治疗的患者两组间无统计学差异(P均>0.05),采用MP治疗PES疗效确切。接受甲基泼尼松龙分层治疗的患者在中性粒细胞、血小板累积植入率及Ⅱ~Ⅳ度急性GVHD、Ⅲ~Ⅳ度aGVHD累积发生率上差异均无统计学意义(P均>0.05)。8例患者UCBT后100d均发生感染,其中细菌感染率75%,巨细胞病毒(CMV)血症发生率100%;无EB病毒(EBV)感染;接受MP0.5mg·kg^(-1)·d^(-1)治疗组细菌感染发生率50%,MP1mg·kg^(-1)·d^(-1)治疗组为100%,两组患者感染发生率上无统计学差异(P均>0.05)。至随访截止,总生存期(OS)及总复发率均无统计学差异(P均>0.05)。结论:UCBT后PES发生率较高,MP对UCBT后PES的治疗效果确切,且根据患者PES症状严重程度进行MP分层治疗可能减少患者感染等移植并发症,提高患者UCBT的移植疗效,延长患者生存。AIM： To retrospectively study the effect of risk adjustment methylprednisolone （MP） intervention on the prognosis of pre-engraftment syn- drome （PES） and impacts on outcomes after unre- lated cord blood transplantation （UCBT）. METHODS： The data of 8 patients with acute leukemia underwent single or double UCBT from November 2012 to March 2015 were analyzed in this study, including 7 single UCBT and 1 double UCBT, half of the patients were acute lymphoblastic leukemia, and the other 4 patients were acute myeloid leukemia. All the patients were received intensified myeloabla- rive conditioning, including 7 sTBI-based conditioning and one based on Flu. Treatment with risk ad- justment methylprednisolone was given to all the pa- tients for PES intervention. And for graft-versus-host disease （GVHD） prophylaxis, a combination of cy- closporine （ CsA ） and mycophenolate mofetil （MMF） was given. The cohort of patients were fol- lowed-up till to August 31, 2016. RESULTS： All the patients showed PES after UCBT and the incidence of PES was 100%. When compared the maximum C-reactive protein （CRP） level, the median value during PES was significantly higher than the serum level during conditioning therapy, after PES and the onset of II-IV acute GVHD （ all P 〈 0.05, respectively）, and the result of patients received dif- ferent doses of MP （0.5 mg·kg^-1·d^-1 and 1 m·kg^-1·d^-1） showed no significant difference （P 〉 0.05）. Treatments based on different doses of MP showed a good clinical effect on PES, and there was no significant difference on transplant-related com- plications such as cumulative incidences of neutro- phil engraftment, platelet recovery, II-IV and III-IV acute GVHD （ all P 〉 0.05, respectively）. What＇s more, all the patients experienced infections in 100 days after UCBT. The incidence of bacterial infection was 75% , and the incidence of CMV infection was 100%. But in this study, no one experienced EBV infection after UCBT. In patients received MP 0.5
