Objective Through conducting a meta-analysis using the methodology of Cochrane review, to assess the effectiveness and safety of graft-versus-host disease (GVHD) prophylaxis with antithymocyte globulins (ATGs) in allogeneic hematopoietic stem cell transplantation (allo-HSCT). Methods Such databases as PubMed (1966 to March 2011), EMbase (1974 to March 2011), the Science Citation Index databases (1900 to March 2011), The Cochrane Library (1996 to March 2011), CBMdisc (1978 to March 2011), and CNKI (1979 to March 2011) were electronical1y searched. The references of all identified studies were retrieved for collecting more randomized controlled trials (RCTs) and non-RCTs. Two reviewers independently screened the trials according to inclusion and exclusion criteria, abstracted the data, and assessed the methodology quality of the included studies. Meta-analyses were performed using RevMan 5.0.2 software. Results Thirteen clinical trials were included, of which 2 were RCTs involving 310 patients and the other 11 were non-RCTs involving 1480 patients. The results of meta-analyses showed that compared with the Non-ATG group, the pooled risk ratio (RR) and 95%CI of the ATG group in acute GVHD II-IV incidence rate, acute GVHD III-IV incidence rate, chronic GVHD (limited plus extensive) incidence rate, chronic GVHD (extensive) incidence rate, overall survival (OS) rate, non-relapse mortality (NRM) rate, and relapse rate were 0.77 (0.67, 0.87), 0.54 (0.44, 0.68), 0.58 (0.51, 0.65), 0.35 (0.26, 0.46), 1.14 (1.04, 1.25), 0.81 (0.69, 0.93), and 1.24 (0.98, 1.57), respectively. Conclusion The addition of ATGs to GVHD prophylaxis can reduce the incidence of acute and chronic GVHD, decrease NRM, and increase OS, but has no obvious interference with relapse rate.
【摘要】 目的 分析異基因造血干細胞移植術（allogeneic hematopoietic stem cell transplantation，allo-HSCT）后出血性膀胱炎（hemorrhagic cystitis，HC）相關的危險因素，動態監測受者尿BK病毒（BK virus，BKV），分析其與HC發病的關系。 方法 回顧性分析2003年3月-2008年1月期間接受allo-HSCT的121例患者的資料，選擇8個臨床參數[年齡、性別、疾病類型、移植時疾病狀態、供者類型、預處理方案、急性移植物抗宿主病（acute graft-versus-host disease，aGVHD）、aGVHD的預防方案]作COX回歸分析。采用SYBR Green染料實時熒光定量聚合酶鏈反應法對2006年9月-2008年1月42例allo-HSCT患者尿BKV載量進行動態監測，分析被檢查者尿液BKV基因載量與HC發生以及嚴重程度的關系。 結果 121例患者中有24例發生HC，發病時間為術后0~63 d，中位時間40 d；持續時間7~150 d，中位時間22 d。Ⅱ~Ⅳ度aGVHD為HC的獨立危險因素[RR=8.304，95%CI（1.223，56.396），P=0.030]。allo-HSCT受者尿液中BKV檢出率為100%（42/42）。與正常人及未發生HC的allo-HSCT受者相比，HC患者尿中BKV基因載量具有更高平均峰值。 結論 Ⅱ~Ⅳ度aGVHD，尿中BKV DNA高載量與HC的發生有相關性。【Abstract】 Objective To identify the risk factors for hemorrhagic cystitis (HC) after allogeneic hematopoietic stem cell transplantation (allo-HSCT), and define the quantitative relationship between BK virus (BKV) DNA load with HC. Methods The medical records of 121 patients undergoing allo-HSCT from March 2003 to January 2008 were retrospectively analyzed. Eight clinical parameters were selected for COX regression analysis, including age, sex, underlying disease, disease status at transplant, donor type, conditioning regimen, acute graft-versus-host disease (aGVHD), and GVHD prophylaxis. From September 2006 to January 2008, mid-stream urine samples were continuously collected from 42 patients with allo-HSCT. SYBR green real-time polymerase chain reaction, technique was utilized to define the quantitative relationship between BKV DNA load and HC. Results Twenty-four out of 121 patients developed HC. The median time of onset was 40 days after HSCT, ranged from 0 to 63 days. The disease lasted for 7 to 150 days, with a median duration of 22 days. Grade Ⅱ-Ⅳ aGVHD [RR=8.304, 95% CI (1.223,56.396); P=0.030] was identified as an independent risk factor for the occurrence of HC. BKV excretion was detected in 100% (42/42) of the recipients of allo-HSCT. When compared with asymptomatic patients and allo-HSCT recipients without HC, patients with HC had a significantly higher mean peak BKV DNA load. Conclusions Patients are at an increased risk of developing HC if they have grade Ⅱ-Ⅳ aGVHD. A correlation between the load of BKV and incidence of HC may exist.
【摘要】 目的 分析異基因造血干細胞移植術（allogeneic hematopoietic stem cell transplantation，allo-HSCT）后并發毛細血管滲漏綜合征（capillary leak syndrome，CLS）的發生率、危險因素和結局，并探討其防治措施。 方法 回顧性分析2005年6月-2011年2月住院的allo-HSCT術后14例并發CLS的臨床資料。 結果 CLS發生率為9.2%（14/152）。年齡、性別、診斷、HLA配型、預處理、CD34+細胞量、粒細胞集落刺激因子（granulocyte colony-stimulating factor，G-CSF）用量、植入時間均不能認定為造血干細胞移植后CLS誘發因素。 結論 HSCT術后CLS誘因尚不清楚，采用限水、減量G-CSF、使用糖皮質激素和羥乙基淀粉等措施及時治療，有助于控制CLS。【Abstract】 Objective To study the occurrence rate, risk factors and outcomes of capillary leak syndrome (CLS) after allogeneic hematopoietic stem cell transplantation (allo-HSCT), and discuss its prevention and treatment. Methods We retrospectively analyzed the clinical records of 14 allo-HSCT recipients complicated with CLS from June 2005 to February 2011. Results Fourteen out of 152 patients developed CLS with a cumulative incidence of 9.2 %. None of the 8 clinical parameters including age, gender, underlying disease, donor type, conditioning regimen, CD34+ cell dose, granulocyte colony-stimulating factor (G-CSF) dosage, and days to neutrophil engraftment could be identified as risk factors for the occurrence of CLS. Conclusions Risk factors for CLS after allo-HSCT have not been fully established. Restriction of water intake, administration of corticosteroids and hydroxyethyl starch can be beneficial for patients with CLS.
目的 建立急性白血病（AL）患者八色流式免疫表型分析起始管方案。 方法 用胞膜CD3（CD3）、CD19、CD10、CD34、CD45、胞漿CD79a（cCD79a）、髓過氧化物酶（MPO)和胞漿CD3（cCD3）等8種抗體建立八色流式染色方案。膜表面抗體直接染色；膜內抗體經固定破膜，再染色后上機檢測。將3個血小板減少患者骨髓標本分別進行抗體的單色染色和缺一色染色；最后對17例確診的AL初發患者標本進行檢測。 結果 用單色染色來確定染色方案中各抗體的檢測電壓及熒光補償；缺一色染色中，陽性細胞群較單色染色變化均＜10%，表明方案中的各抗體相互作用小。17例AL初發患者中，6例急性B淋巴細胞白血病原始細胞均為CD34和CD19陽性，5例cCD79a陽性和4例CD10陽性；4例急性T淋巴細胞白血病患者均為cCD3陽性；6例急性髓細胞白血病均為CD34和MPO陽性；1例B+T混合表型AL患者CD34、cCD3、CD19、cCD79a及CD10均為陽性，MPO和CD3為陰性，此檢測方案能夠確定各類AL的細胞類型。 結論 建立了AL患者八色流式免疫表型分析起始管方案，操作簡便快速，適用于臨床檢測。
