Analysis of the Risk Factors for Hemorrhagic Cystitis after Hematopoietic Stem Cell Transplantation / 中国实验血液学杂志

OBJECTIVE@#To analyze the risk factors affecting hemorrhagic cystitis(HC) after allogeneic hematopoietic stem cell transplantation(allo-HSCT).@*METHODS@#The clinical data of 153 patients underwent allogeneic hematopoietic stem cell transplantation in the First Affiliated Hospital of Xi'an Jiaotong University from January 2010 to December 2018 were selected and retrospectively analyzed. The incidence, median time and treatment outcome of HC should be observed. Multivariate analysis was used to observe the risk factors of HC in patients, including sex, age, diagnosis, disease status before transplantation, transplantation type, ATG and CTX in the pretreatment scheme, stem cell source, neutrophil and platelet implantation time; CMV, EBV and BKV infection, and acute graft-versus-host disease(aGVHD).@*RESULTS@#Among 153 patients underwent allogeneic hematopoietic stem cell transplantation, 25 (16.34%) patients had HC, the median occurance time was 31 days, all patients achieved complete remission after treatment, no bladder irritation and bladder contracture were left. The results of univariate and multivariate Logistic regression analysis showed that the type of transplantation, ATG, CMV viremia before treatment, aGVHD (r=1.036, 3.234, 3.298 and 2.817, respectively) were the independent risk factors of HC.@*CONCLUSION@#The urinary BKV detections in the patients with HC are positive, mainly occured during the period from day +13 to days +56. HLA haplotype, pretreatment including ATG, and CMV viremia, and aGVHD are the independent risk factors for HC after allo-HSCT.

Risk Factors and Therapeutic Outcome of Intestinal Acute Graft Versus Host Disease in Acute Leukemia Patients after Haploidentical Peripheral Hematopoietic Stem Cell Transplantation / 中国实验血液学杂志

<p><b>OBJECTIVE</b>To investigate the risk factors and therapeutic outcome of acute graft versus host disease (aGVHD) in patients with acute leukemia after haploidentical peripheral hematopoietic stem cell transplantation.</p><p><b>METHODS</b>The clinical data of 19 cases of acute leukemia underwent haploidentical hematopoietic stem cell transplanttion during January 2010 and December 2010 were retrospectively analyzed. The effects of patients sex, donor-recipient sex difference, donor age, conditioning regimen, dosage of anti-thymocyte globulin(ATG), mononuclear cell and CD34cell counts on the intestinal aGVHD were analyzed by Logistic regression.</p><p><b>RESULTS</b>Intestinal aGVHD occurred in 5 cases with 1 case at stage II 3 cases at stage III and 1 case at stage IV on the 7th, 22th, 27th, 70th and 154th day after transplantation, respectively. Single factor analysis showed that the patient's sex, donor-recipient sex difference, donor age, dosage of ATG, mononuclear cell and CD34cell counts were not related with the occurrence of the intestinal aGVHD, and the conditoning regimen was the risk factor for the intestinal aGVHD. 2 cases among 5 cases with intestinal aGVHD were treated with methylprednisolone at dosage of 1 mg/kg per day, 1 case was treated with methylprednisolone therapy combined with tacrolimus. 2 cases of methylprednisolone-resistance were treated with CD25 monoclonal antibody. Intestinal aGVHD of all patients was improved after the above-mentioned treatment.</p><p><b>CONCLUSION</b>Conditioning regimen of haploidentical peipheral hematopoieitc stem cell transplantaion has effects on the intestinal aGVHD, which needs to be confirmed by further research.</p>
