Methods Between January 2002 and December 2010, six patients with severe hepatic veno-occlusive disease accompanied with hematopoietic stem cell transplantation underwent plasma exchange with plasma exchange procedures using artificial liver support system. Results After plasma exchange treatment, the bilirubins of six patients significantly decreased; three patients eventually recovered, two died because of liver function deteriorated again, and one died of severe mixed infections. Conclusion Artificial liver support system is effective and reliable for hematopoietic stem cell transplantation accompanied with severe hepatic veno-occlusive disease.
Objective To evaluate the effectiveness and safety of autologous hemopoietic stem cell implantation for peripheral arterial disease (PAD). Methods Randomized controlled trials (RCTs) were identified from CBM (1978 to September 2010), CNKI (1979 to September 2010), MEDLINE (1950 to September 2010), Pubmed (1950 to September 2010), Embase (1970 to September 2010), and Cochrane l ibrary (issue 4, 2010). The papers of the RCTs of cl inical therapeutic studieson PAD treated by autologous hemopoietic stem cell implantation were included and analyzed according to the criteria of the Cochrane handbook. Results Eight RCTs involving 280 patients and 322 extremities were included, with majority of trials of low methodological qual ity. Meta-analysis indicated that autologous hemopoietic stem cell transplantation had an increased ulcer cure rate [RD=0.38, 95% CI= (0.25, 0.50)], a significant improvement in the ankle brachial index [MD=0.11, 95%CI= (0.04, 0.18)], transcutaneous oxygen tension [MD=7.33, 95%CI= (3.14, 11.51)], and pain-free walking distance [SMD=1.35, 95%CI= (0.90, 1.79)], a significant reduction in rest pain scores [MD= —1.70, 95%CI= (—2.15, —1.25)], and a significant benefit in terms of l imb salvage [RD= —0.19, 95%CI= (—0.31, —0.07)]. Only 2 trials reported the side effects of autologous hemopoietic stem cell transplantation, such as l imbs swell ing and concentrations of serum creatine phosphokinase increasing, and the long-term safety was not reported. Conclusion Based on the review, autologous hemopoietic stem cell transplantation may have positive effect on “no-option” patients with PAD. However, the evidence is not b enough due to the general low methodological qual ity, so we can not draw a rel iable conclusion about the effects of autologous stem cell transplantation for PAD at the moment. Further larger, randomized, double bl ind, placebo-controlled, and multicenter trials are needed.
【摘要】 目的 分析异基因造血干细胞移植术（allogeneic hematopoietic stem cell transplantation，allo-HSCT）后出血性膀胱炎（hemorrhagic cystitis，HC）相关的危险因素，动态监测受者尿BK病毒（BK virus，BKV），分析其与HC发病的关系。 方法 回顾性分析2003年3月-2008年1月期间接受allo-HSCT的121例患者的资料，选择8个临床参数[年龄、性别、疾病类型、移植时疾病状态、供者类型、预处理方案、急性移植物抗宿主病（acute graft-versus-host disease，aGVHD）、aGVHD的预防方案]作COX回归分析。采用SYBR Green染料实时荧光定量聚合酶链反应法对2006年9月-2008年1月42例allo-HSCT患者尿BKV载量进行动态监测，分析被检查者尿液BKV基因载量与HC发生以及严重程度的关系。 结果 121例患者中有24例发生HC，发病时间为术后0~63 d，中位时间40 d；持续时间7~150 d，中位时间22 d。Ⅱ~Ⅳ度aGVHD为HC的独立危险因素[RR=8.304，95%CI（1.223，56.396），P=0.030]。allo-HSCT受者尿液中BKV检出率为100%（42/42）。与正常人及未发生HC的allo-HSCT受者相比，HC患者尿中BKV基因载量具有更高平均峰值。 结论 Ⅱ~Ⅳ度aGVHD，尿中BKV DNA高载量与HC的发生有相关性。【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.
ObjectiveTo observe the clinical features of cytomegalovirus (CMV) retinitis (CMVR)-related uveitis after hematopoietic stem cell transplantation (HSCT).MethodsA retrospective clinical study. From October 2015 to May 2020, 14 cases of 21 eyes of CMVR patients with CMVR after HSCT confirmed by the ophthalmological examination of The First Affiliated Hospital of Soochow University were included in the study. Among them, there were 5 males with 8 eyes and 9 females with 13 eyes. The average age was 35.12±12.24 years old. All the affected eyes were examined by slit lamp microscope combined with front lens and fundus color photography. At the same time, fluorescein fundus angiography (FFA) was performed to examine 10 eyes of 5 cases; 3 cases of 3 eyes were examined for inflammatory cytokines in aqueous humor. All eyes received intravitreal injection of ganciclovir; patients with a history of systemic CMV infection received intravenous infusion of ganciclovir/foscarnet. The retinal lesions in the eye were completely resolved or the aqueous CMV-DNA was negative as a cure for CMVR. The uveitis symptoms, signs, FFA manifestations and the test results of inflammatory factors in aqueous humor before and after the CMVR cure was observed. The follow-up time after CMVR was cured was 3-42 months, and the average follow-up time was 14.28±13.12 months.ResultsAll eyes with CMVR were diagnosed with retrocorneal dust and/or stellate keratic precipitates (KP), anterior chamber flare and cells, and varying degrees of vitreous flocculent opacity; the retina was typical of a mixture of hemorrhage and yellow-white necrosis like "scrambled eggs with tomatoes". After CMVR was cured, there were 16 eyes (71.4%, 10/14) in 10 cases with KP, anterior chamber flare, cell and vitreous opacity. FFA examination revealed that the majority of retinal leakage during the active period of CMVR was necrotic foci and surrounding tissues; after CMVR was cured, the majority of retinal leakage was the retina and blood vessels in the non-necrotic area. The test results of inflammatory factors in aqueous humor showed that interleukin (IL)-6, IL-8, and vascular endothelial cell adhesion molecules were significantly increased in the active phase of CMVR; after 3 months of CMVR cured, inflammatory factors did not increase significantly.ConclusionCMVR-associated uveitis after HSCT show as chronic panuveitis, with no obvious eye congestion, KP, anterior chamber flare, cell and vitreous opacity, and retinal vessel leakage which could exist for a long time (＞3 months).
目的 调查造血干细胞移植出院患者的社会支持现状，寻求相应的护理对策，帮助患者保持较高的社会支持水平。 方法 选择2007年9月-2009年3月在层流病房进行造血干细胞移植的患者48例，采用肖水源的社会支持评定量表，进行住院期间和出院3个月后的问卷调查，并进行统计学分析。 结果 患者住院期间社会支持总分为(41.40±5.60)分，出院3个月后社会支持总分为(38.19±3.65)分，比较具有统计学意义(Plt;0.05)。 结论 造血干细胞移植患者出院后社会支持水平降低，护士应加强对造血干细胞移植患者出院后的指导，拓宽造血干细胞移植出院患者社会支持渠道，帮助患者保持较高的社会支持水平，从而促进患者的康复。
ObjectiveTo systematically review the efficacy and safety of non-myeloablative stem cell transplantation (NST) for the treatment of multiple myeloma (MM) after first autologous stem cell transplantation. MethodsSuch databases as The Cochrane Library (Issue 5, 2013), PubMed, EMbase, CBM, CNKI, VIP and WanFang Data were electronically searched to collect studies investigated the efficacy and safety of NST and non-NST for the treatment of MM after first autologous stem cell transplantation from the date of their establishment to June 13th 2013. Two reviewers independently screened studies according to the inclusion and exclusion criteria, extracted data and evaluated the methodological quality of the included studies. Then meta-analysis was performed using RevMan 5.1 software. ResultsSeven studies involving 1 961 participants were included, of which 626 cases were in the NST group and 1 335 cases were in the non-NST group. The results of meta-analysis showed that no significant difference was found between both groups in the overall survival rate (HR=1.06, 95%CI 0.78 to 1.44, P=0.69) and progress-free survival rate (HR=0.92, 95%CI 0.76 to 1.11, P=0.39). However, there were significant differences in the complete remission rate (RR=1.29, 95%CI 1.13 to 1.48, P=0.000 2) and treatment-related mortality rate (RR=3.40, 95%CI 2.27 to 5.07, P < 0.000 01). ConclusionThe efficacy of NST is not superior to non-NST for patients with MM which has received first autologous stem cell transplantation. It is not sufficient to recommend NST as the first-line treatment of MM based on the currently available evidence.
ObjectiveTo systematically review the efficacy of double autologous hematopoietic stem cell transplantation (ASCT) in newly diagnosed multiple myeloma (NDMM). Methods PubMed, EMbase, The Cochrane Library, CNKI, and WanFang Data databases were electronically searched to collect randomized controlled trials (RCTs) on double ASCT for NDMM from inception to February 2021. Two reviewers independently screened literature, extracted data and assessed the risk of bias of included studies. Meta-analysis was then performed by RevMan 5.3 software. Results A total of 6 RCTs involving 2 226 NDMM patients were included. The results of meta-analysis indicated that compared with single ASCT, more patients who received double ASCT could achieve satisfactory partial response (VGPR) or better (RR=1.12, 95%CI 1.01 to 1.25, P=0.03). Double ASCT resulted in a higher progression-free survival (PFS) rate from the second year for high-risk patients (2-year: RR=0.49, 95%CI 0.28 to 0.86, P=0.01; 5-year: HR=0.61, 95%CI 0.43 to 0.85, P=0.004). There were no statistical differences in treatment-related mortality and 5-year overall survival between the two groups. ConclusionsCompared with single ASCT, double ASCT can improve the VGPR rate of NDMM patients and the PFS rate of high-risk patients with comparable toxicities. Due to limited quality and quantity of the included studies, more high-quality studies are needed to verify the above conclusions.
Objective To systematically review the survival outcome and safety of haploidentical hematopoietic stem cell transplantation (haplo-HSCT) for β-thalassemia. Methods The PubMed, EMbase, CNKI, WanFang Data and CBM databases were electronically searched to collect studies on haplo-HSCT for β-thalassemia from January 1, 2017 to December 31, 2021. Two reviewers independently screened the literature, extracted data and assessed the risk of bias of the included studies. Meta-analysis was then performed by using RevMan 5.4.1 software and Stata 16.0 software. Results A total of 6 case-series studies involving 286 patients were included. The results of meta-analysis indicated that overall survival (OS) and thalassemia-free survival (TFS) for β-thalassemia patients undergoing haplo-HSCT were 92.5% (95%CI 86.1% to 96.1%) and 88.5% (95%CI 74.6% to 95.3%), the incidence of Ⅲ-Ⅳ degree acute graft versus host disease (Ⅲ-Ⅳ aGvHD) and chronic graft versus host disease (cGvHD) were 11.5% (95%CI 6.5% to 20.0%) and 23.1% (95%CI 12.3% to 39.8%), and the transplantation related mortality was 6.5% (95%CI 3.8% to 10.7%). Conclusion Relevant clinical studies published in the past 5 years provide the latest information and progress of haplo-HSCT for β-thalassemia. At present, great efficacy has been shown in NF-14-TM therapeutic regimen, but the long-term efficacy remains unclear. Due to the limited quality and quantity of the included studies, more high-quality evidence from long-term comparative studies is still needed.
