BACKGROUND: Hemorrhagic cystitis remains a common complication of hematopoietlc stem cell transplantation.Granulocyte-macrophage colony stimulating factor (GM-CSF) affects proliferation and differentiation of hematopoietic stem/progenitor cells, adjusts functions of monocytes, granulocytes, lymphocytes and endothelial cells.OBJECTIVE: To investigate the protective effects of GM-CSF bladder irrigation in hemorrhagic cystitis after allogeneic hematopoietic stem call transplantation.DESIGN: Case analysis.PARTICIPANTS: A total of 15 hematopathy patients undergoing allogenic hematopoietic stem cell transplantation at the Zhongshan Hospital of Sun Yat-sen University from January 2004 to August 2006 (routine treatment group). A total of 16 hematopathy patients undergoing allogenic hematopoietic stem cell transplantation from September 2006 to December 2008 (GM-CSF group).METHODS: In the routine treatment group, patients received mesna, hydration, alkalization and forced diuresis in the prevention of hemorrhagic cystitis. In the GM-CSF group, GM-CSF was infused into the bladder in addition to mesna,hydration, alkalization and forced diuresis in the prevention of hemorrhagic cystitis 24 hours before cyclophosphamide treatment. Catheter was extracted 3 days following cyclophosphamide withdraw. Following washing with saline, the bladder was emptied. 10 mL of saline and 5 mL of lidocaine were added into 300 μg of GM-CSF. The mixture was infused into the bladder for 60-120 minutes.MAIN OUTCOME MEASURES: The following parameters were measured: occurrence of hemorrhagic cystitis and its correlation to graft versus host disease, as well as the occurrence of cytomegalovirus infection and urinary system infection.RESULTS: Compared with routine treatment group, the occurrence rate of hemorrhagic cystitis was significantly decreased in the GM-CSF group (x2=4.39, P < 0.05), mean duration of hemorrhagic cystitis and duration of hospitalization were significantly shortened (t=3.97, P < 0.05; t=3.13, P < 0.05), and the occurrence rate of over grade HI hemorrhagic cystitis was significantly reduced (x2=5.04, P < 0.05). Cystitis degree was associated with degree and duration of graft-versus-host disease (r = 0.76).Compared with the routine treatment group, cytomegalovirus infection rate was slightly decreased in the GM-CSF group (x2=0.28, P> 0.05), and occurrence rate of over grade Ⅲ hemorrhagic cystitis was higher in patients with cytomegalovirus infection.Compared with the routine treatment group, the occurrence rate of urinary system infection was slightly reduced in the GM-CSF group (x2=0.28, P > 0.05).CONCLUSION: GM-CSF bladder irrigation is well tolerated and often effective, and should be considered as a preparative regimen of hemorrhagic cystitis after allogeneic hematopoietic stem call transplantation.

Objective To explore the high-risk factors,clinical characteristics,therapy and prognosis of invasive fungal infection (IFI)in patients underwent allogeneic haemopoietic stem cell transplantation (AlloHSCT). Methods One hundred patients underwent Allo-HSCT at our department from March 2002 to July 2010 were analyzed retrospectively,among whom 26 patients had invasive fungal infection(IFI). Seven patients had pulmonary IFI before allo-HSCT, 14 patients had pulmonary IFI after allo-HSCT,3 patients had respiratory tract system IFI, and 2 patients had intestinal IFI. We observed the occurrence of Graft-versus-host disease (GVHD) ,cytomegalovirus( CMV )infection, Lymphocyte subsets and chronic basic diseases in patients with IFI. The twenty six cases were divided into two groups: experience therapy group with 12 cases and preemption therapy group with 14 cases. Results Among 26 patients with IFI,20 cases suffered from GVHD,6 cases had CMV infection,19 cases had low cellular immune function simultaneously. 1 case had diabetes,3 patients had pulmonary tuberculosis and 1 case had bronchiectasis as complications. In experience therapy groupe: 8 cases (67%)recovered completely but 1 case(8% )suffered from progressive infection. In preemption therapy groupe:3 cases ( 21% ) recovered completely but 5 cases ( 36% ) suffered from progressive infection. Conclusion Clinician should pay close attention to the patients with high-risk factors of IFI after allo-HSCT.

Objective To evaluate the therapeutic effects of allogeneic hematopoietic stem cell transplantat (allo-HSCT) for severe aplastic anemia (SAA). Methods Four patients of SAA underwent allo-HSCT at the bonemarrow transplant unit in our hospital from March 2003 to May 2009. Stem cell source was an HLA (human leukocyte antigen) matched related donor (MRD) in 3, HLA 1 (B) mismatched related donor in 1 patient A retrospective analysis was performed on interval from diagnosis to transplant,HSCT manners,conditioning regimens, hematopoiesis reconstitution, effectiveness and complication. Results The interval from diagnosis to transplant was 70 (19 - 180) days. Three patients (MRD) underwent BM + PBSCT, one was undergone BM + PBSC + CBSCT. Conditioning regimens of all patients were CY/ATG. Hematopoiesis reconstitution was achieved in 4 patients (100%). The median time of neutrophils which reached 0. 5 x 109/L and platelets reached 20 × 109/L were 14. 5 (9-28) and 16(9 -28) days. Two cases developed grade Ⅰ acute graft-versus-host diseaes (aGVHD), chronic local GVHD occurred in one patient. Four patients are alive with a median time of 40. 6(2 -63) months at the end of the following-up. Conclusions Allo-HSCT are an efficient and safe therapy for the patient with SAA,not only for patients with HLA matched related donor,but also for those only HLA mismatched related donor available.

BACKGROUND:Donor selection for high-risk acute leukemia is still controversial.OBJECTIVE:To compare the therapeutic efficacy of the unrelated donor peripheral blood and matched sibling allogeneic hematopoietic stem cell transplantation for high-risk acute leukemia.METHODS:Total 65 patients with high-risk acute leukemia treated during January 2008 to January 2016 were included,in which 30 patients chose the unrelated donor peripheral blood stem cell transplantation (UD), and other 35 chose the matched sibling allogeneic hematopoietic stem cell transplantation (MS) according to the wishes of patients and their own situation. After treatment, the chi-square test, Kaplan-Meier survival analysis method, and other methods were used to compare the implanted and hematopoietic reconstitution, the occurrence of graft-versus-host disease, relapse mortality and long-term survival between the two groups.RESULTS AND CONCLUSION:The implantation rate, platelet hematopoietic reconstitution time, the incidence of acute and chronic graft-versus-host disease, and its type exhibited no significant differences between the two groups (P > 0.05).The relapse rate, total death rate, and transplant-related mortality rates were 10.0%, 50.0%, and 40.0% in the UD group and 20.0%, 48.6%, and 25.7% in the MS groups, respectively, and the intergroup difference was insignificant (P > 0.05).The expected 2-year cumulative disease-free free survival and overall survival rates were (49.4±9.2)% and (52.6±9.2)% in the UD group and (53.9±8.5)% and (53.9±8.5)% in the MS group, respectively, and the intergroup difference was also insignificant (P > 0.05). Our experimental findings show that unrelated donor peripheral blood stem cell transplantation can be used as an effective alternative in the absence of sibling donors.
