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).
Cytomegalovirus (CMV) retinitis (CMVR) is a common opportunistic infection of the eye after allogeneic hematopoietic stem cell transplantation in patients with hematological diseases. It often occurs within 3 months after the operation, with CMV activation and high blood CMV peaks. It often occurs on patients with long-term CMV viremia, human leukocyte antigen incompatible transplantation, unrelated donor transplantation, haploid transplantation, childhood hematopoietic stem cell transplantation, delayed lymphocyte engraftment, acute and chronic graft-versus-host disease after surgery. The visual prognosis of patients is related to the area of CMVR lesions on the retina, the number of quadrants involved, whether the macula is involved, and the CMV load of the vitreous body is involved, and it is not related to whether the Epstein-Barr virus infection is combined with blood and vitreous humor. The incidence of CMVR is increasing year by year. It is helpful that paying attention to systemic risk factors and epidemiology can provide more effective guidance for ophthalmologists during diagnosis and treatment, help patients improve the prognosis of vision, and reduce or even avoid the occurrence of blindness caused by CMVR.
【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 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.
ObjectivesTo systematically review the efficacy and safety of palifermin on oral mucositis (OM) and acute graft versus host disease (aGVHD) for hematological malignancy patients undergoing hematopoietic stem cell transplantation (HSCT).MethodsPubMed, The Cochrane Library, Web of Science, EMbase, Clinicaltrials.gov, CNKI and WanFang Data databases were electronically searched to collect randomized controlled trials (RCTs) of the efficacy of palifermin on OM and aGVHD for hematological malignancy patients undergoing HSCT from inception to September 30th, 2018. Two reviewers independently screened literature, extracted data and assessed the risk of bias of included studies, then, meta-analysis was performed by using RevMan 5.3 software.ResultsA total of 7 RCTs involving 904 patients were included. The results of meta-analysis showed that: palifermin could reduce the duration of OM grade 2 to 4 (MD=−4.21, 95%CI −7.83 to −0.58, P=0.02), OM grade 3 to 4 (MD=−2.54, 95%CI −4.61 to −0.46, P=0.02) significantly for hematological malignancy patients undergoing HSCT. However, no significant difference was found in the prevalence of aGVHD grade 2 to 4 (RR=1.29, 95%CI 0.95 to 1.75, P=0.11), aGVHD grade 3 to 4 (RR=0.99, 95%CI 0.55 to 1.77, P=0.97), OM grade 2 to 4 (RR=0.86, 95%CI 0.72 to 1.03, P=0.11) and OM grade 3 to 4 (RR=0.82, 95%CI 0.65 to 1.03, P=0.08) between palifermin group and placebo group. The prevalence of paresthesia (RR=4.24, 95%CI 1.24 to 14.56, P=0.02) and erythema (RR=1.49, 95%CI 1.06 to 2.09, P=0.02) were significantly higher in palifermin group.ConclusionsThe durations of OM grade 2 to 4, 3 to 4 are significantly reduce in patients receiving palifermin compared with those receiving a placebo, however, no statistically significant difference are found in the incidence of aGVHD grade 2 to 4, 3 to 4, OM grade 2 to 4, 3 to 4. Parethesia and erythema are more prevalent among patients using palifermin. Therefore, advantages and disadvantages of palifermin should be considered when used in clinical.
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.
