Risk factors of hemorrhagic cystitis after allo-HSCT and therapeutic effects of early transfusion of umbilical cord mesenchymal stem cells / 中华器官移植杂志

Objective:To explore the clinical efficacy and risk factors of umbilical cord mesenchymal stem cells (UCMSCs) infusion at an early stage (i.e.gross hematuria) for hemorrhagic cystitis (HC) after allogeneic hematopoietic stem cell transplantation (allo-HSCT).Methods:The relevant clinical data were retrospectively reviewed for 300 patients undergoing allo-HSCT from January 2016 to July 2021.According to the presence or absence of HC, they were assigned into two groups of HC (n=89) and non-HC (control, n=211). According to whether or not receiving an infusion of UCMSCs, 51 patients of HC degree Ⅱ-Ⅳ were divided into two groups of UCMSC infusion and non-infusion.The risk factors of HC after allo-HSCT were analyzed by χ2 test.Logistic regression was employed for multivariate analysis of P<0.05.Mann-Whitney U test was utilized for statistically analyzing the duration of gross hematuria and urinary tract irritation symptoms and evaluating the clinical efficacy of UCMSCs infusion for HC. Results:Among them, 89 (29.67%) developed HC post-allo-HSCT.Clinical grades were Ⅰ (n=38, 42.70%), Ⅱ (n=36, 40.45%), Ⅲ (n=13, 14.61%) and Ⅳ (n=2, 2.25%). The median occurrence time was 29 (21.5-35.0) days post-allo-HSCT.In univariate analysis, age ≤30 years, haploid transplantation, antithymocyte globulin (ATG), acute graft-versus-host disease (aGVHD), CMV-DNA positive pretreatment significantly boosted the risk of HC ( P<0.05). In multivariate analysis, aGVHD was an independent risk factor for HC ( OR=10.281, 95% CI: 1.606-65.813, P=0.014). Among 89 HC patients, 38 grade Ⅰ patients were complete remission(CR). Among 51 patients of grade Ⅱ-Ⅳ HC, the outcomes were CR (n=48) and non-remission(NR)(n=3). And 24/51 of them received UCMSCs plus conventional treatment.The duration of gross hematuria was shorter in UCMSCs infusion group than that in UCMSCs non-infusion group [12(9-17) vs 17(12.0-26.5) day] and the difference was statistically significant ( P=0.045). And the duration of urinary tract irritation symptoms was shorter in UCMSCs infusion group than that in UCMSCs non-infusion group [18(11-30) vs 27(18.0-35.5) days] and the difference was statistically significant ( P=0.048). Conclusions:Indicated for post-ALLO-HSCT HC, infusion of UCMSCs may significantly shorten the course of disease.Age ≤30 years, haploid transplantation and preconditioning with positive ATG, aGVHD and CMV-DNA may boost the risks of HC post-allo-HSCT.And aGVHD is an independent risk factor for HC after allo-HSCT.

Outpatient haploidentical hematopoietic stem cell transplant using post-transplant cyclophosphamide and incidence of hemorrhagic cystitis

Abstract Introduction Hemorrhagic cystitis (HC) is a common complication of haploidentical hematopoietic stem cell transplantation (haplo-HSCT), characterized by irritative symptoms of the urinary tract and a higher morbidity and mortality rate. The worldwide incidence is reported between 10% and 70%. The use of alkylating agents and BK viral infection are the most frequent etiologies. The aim of this study was to report the HC incidence in an outpatient haplo-HCST program with a reduced intensity-conditioning (RIC) regimen, cataloguing risk factors, complications and final outcomes. Methods The medical database of patients who received a haplo-HSCT between January 2012 and November 2017 was retrospectively analyzed. Demographic variables, general characteristics and HC incidence were included. Results One hundred and eleven patients were included, 30 (27%) of whom developed HC, most of them (70%) being grade II, with a 30-day (7-149) median time of post-transplant HC onset. The BK virus was detected in 71% of the urine samples analyzed. All HC patients responded to treatment, except two (6.6%), who died due to HC complications. Conclusions There was no difference in the HC incidence or severity, compared to that reported when performing haplo-HSCT in hospitalized patients, although the donor-recipient sex mismatch did relate to a higher HC incidence.

A Case of Hemorrhagic Cystitis that Developed During Administration of Cyclophosphamide for Idiopathic Thrombocytopenic Purpura Successfully Treated with Kamikihito / 日本東洋医学雑誌

A 71-year-old woman was referred to our hospital with complaints of gross hematuria. She had been administered 50mg/day of cyclophosphamide for 13 years to treat idiopathic thrombocytopenic purpura (ITP). Cystoscopy revealed irregular surface of bladder mucosa. On suspicion of bladder cancer, we performed transurethral resection of bladder tumor (TURBT). The pathological examination showed polypoid cyst, and we diagnosed hemorrhagic cystitis. Two months after the operation, gross hematuria was observed again. Although we administered choreitogoshimotsuto and then saireito, both were ineffective. Then we administered kamikihito, considering the findings of deficiency of ki (qi) and ketsu (blood) in Kampo diagnosis and the underlying disease ITP. One month after administering kamikihito, gross hematuria disappeared, urinary sediment test showed RBC 1-4/HPF. After one year of follow-up, bladder tumor was suspected by cystoscopy, but the pathological result of the second TUR-BT was inflammatory change. Since then, kamikihito was continued during the 44-month observation period, and no gross hematuria was observed.

The Efficacy of Choreitogoshimotsuto for Radiation Hemorrhagic Cystitis / 日本東洋医学雑誌

We investigated the efficacy of choreitogoshimotsuto for radiation hemorrhagic cystitis. Of the 11 patients who could be followed up, hematuria disappeared in 8 cases. The median time to disappearance of gross hematuria was 74 days. There was no recurrence. Of the 3 ineffective patients, one had urinary diversion, and two had transurethral electrocoagulation and hyperbaric oxygen therapy. There were no adverse events associated with the use of choreitogoshimotsuto. Choreitogoshimotsuto might be effective for radiation hemorrhagic cystitis.

Hemorrhagic cystitis and giant condyloma acuminatum of anus in a receptor of haploidentical hematopoietic transplant / Cistitis hemorrágica y condiloma acuminado gigante del ano en un receptor de trasplante hematopoyético haploidéntico

ABSTRACT Introduction: The reactivations of latent virus after bone marrow transplants affect the outcome of these patients. Hemorrhagic cystitis caused by BK virus, constitute a frequently lethal complication characterized by abdominal pain, hematuria and renal damage. The incidence is between 13-70 % in hematopoietic transplant receptors. The management includes antibiotics, antivirals, hyperhydration and forced diuresis, platelets and hyperbaric oxygen. Condyloma acuminatum of the anus associated to human papillomavirus is rare among transplanted patients (0.3-1.3 %). It is characterized by an invading mass in the region of the anus producing pain and bleeding. The treatment of choice is the surgical resection of the tumor. Objectives: To describe the clinical characteristics and evolution of hemorrhagic cystitis and anal condyloma acuminatum in a receptor of haploidentical hematopoietic transplant. Discussion: A 20-year-old man with diagnosis of acute myeloid leukemia, on day +21 post-transplant presented macroscopic hematuria associated to BK virus reactivation and resolved with hyperbaric oxygen. On day + 59 post-transplant, anal pain started and a perianal, cauliflower-like mass over 5 cm, was observed. He was diagnosed with condyloma acuminatum of the anus and surgical resection was successfully performed. Conclusions: We reported a unique case of concurrence of both, hemorrhagic cystitis and condyloma acuminatum of the anus after haploidentical hematopoietic transplant. The proper management of these two pathologies allowed a satisfactory evolution of the patient.

RESUMEN Introducción: La reactivación de virus latentes en el organismo después del trasplante de progenitores hematopoyéticos (TPH) afecta la evolución de estos pacientes. La cistitis hemorrágica por virus BK constituye una complicación frecuentemente mortal caracterizada por dolor suprapúbico, hematuria y daño renal. La incidencia varía entre 13 y 70 % de los receptores de trasplante hematopoyético. El tratamiento comprende el uso de antibióticos, antivirales, hidratación y diuresis forzada, plaquetas y oxígeno hiperbárico. El condiloma acuminado del ano asociado al virus del papiloma humano es extremadamente raro en pacientes trasplantados (0,3-1,3 %). Se caracteriza por una masa que invade la región del ano produciendo dolor y sangramiento. El tratamiento de elección consiste en la resección quirúrgica del tumor. Objetivos: Describir las características clínicas, el manejo y la evolución de cistitis hemorrágica y condiloma acuminado anal en un receptor de trasplante hematopoyético haploidéntico. Presentación del caso: Paciente de 20 años de edad con diagnóstico de leucemia mieloide aguda que en el día + 21 del trasplante comenzó con hematuria macroscópica asociada a virus BK que resolvió con oxígeno hiperbárico. En el día +59 comenzó con dolor anal y se observó una masa perianal en forma de coliflor de aproximadamente 5 cm. Se diagnosticó condiloma acuminado del ano y se realizó resección quirúrgica del tumor con todo éxito. Conclusiones: Se presenta un caso único donde concurren cistitis hemorrágica y condiloma acuminado del ano después del trasplante hematopoyético haploidéntico. El manejo apropiado de estas dos patologías condujo a la evolución satisfactoria del paciente.

Cistitis hemorrágica por infección viral en receptores de trasplante hematopoyético haploidéntico: reporte de dos casos / Hemorrhagic cystitis due to viral infection in patients who received hematopoietic haploidentical transplantation: two case reports

Introducción: Las infecciones por virus o la reactivación de virus en estado latente son frecuentes durante el estado de inmunosupresión que sigue al trasplante de progenitores hematopoyéticos, y constituyen una causa importante de complicaciones, como la cistitis hemorrágica, que se caracteriza por disuria, polaquiuria, dolor abdominal y hematuria. La aparición precoz se asocia a la administración de citostáticos como la ciclofosfamida, y el comienzo tardío a la primoinfección o reactivación de virus como citomegalovirus, los adenovirus o los poliomavirus como el BK y el JC. Objetivo: Describir las características clínicas, la evolución y el manejo de la cistitis hemorrágica postrasplante. Casos clínicos: Se presentan dos pacientes con leucemia mieloide aguda que desarrollaron cistitis hemorrágica asociada a infección viral por virus BK y citomegalovirus después del trasplante haploidéntico con ciclofosfamida postrasplante. La cistitis hemorrágica de causa viral después del trasplante hematopoyético en estos pacientes estuvo asociada a una severa inmunosupresión, por lo que constituyó una complicación potencialmente letal. Los dos pacientes presentaron cistitis hemorrágica grado IV y fallecieron a pesar del tratamiento. Conclusiones: El trasplante haploidéntico con la administración de ciclofosfamida postrasplante incrementa la posibilidad de donantes de progenitores hematopoyéticos para los pacientes sin un hermano HLA idéntico pero el mayor nivel de inmunosupresión podría aumentar la incidencia de cistitis hemorrágica de causa viral(AU)

Introduction: Viral infections or latent-virus reactivation are frequent during the immunosuppressed cincition that follows hematopoietic stem-cell transplantation, and an important cause of complications, such as hemorrhagic cystitis, characterized by dysuria, urinary frequency, abdominal pain, and hematuria. The early appearance is associated with the administration of cytostatic drugs such as cyclophosphamide, and the late onset is associated with primary infection or reactivation of viruses such as cytomegalovirus, adenoviruses, or polyomaviruses such as BK and JC. Objective: To describe the clinical characteristics, evolution and management of post-transplant hemorrhagic cystitis. Clinical cases: The cases are presented of two patients with acute myeloid leukemia who developed hemorrhagic cystitis associated with viral infection by BK virus and cytomegalovirus after haploidentical transplantation with post-transplant cyclophosphamide. Viral hemorrhagic cystitis after hematopoietic transplantation in these patients was associated with severe immunosuppression, making it a potentially lethal complication. Both patients presented grade IV hemorrhagic cystitis and died despite treatment. Conclusions: Haploidentical transplantation with the of post-transplant cyclophosphamide administration increases the possibility for donors of hematopoietic progenitor cells to patients without an identical HLA match, but the higher level of immunosuppression could increase the incidence of viral hemorrhagic cystitis(AU)

Objective To investigate the clinical efficacy of hemocoagulase for severe hemorrhagic cystitis (HC) following allogeneic hemotopoietic stem cell transplantation (HSCT). Methods Twenty patients undergoing allogeneic HSCT developed severe HC with an onset time of 14 to 70 days, all patients received the treatment of hemocoagulase (1 U ivgtt q12 h × 5 d). The urine speciments reserved before and after hemocoagulase were examined by naked eye and microscope to evaluate the efficacy. Results Twenty patients received the treatment of hemocoagulase. The HC was cured in 18 patients, improved in 1 patient and uncontrolled in 1 patient. For the patients with response, macroscopic hematuria disappeared at a median of 28 days (4-127 days) after the treatment. All procedures were tolerated well and no severe adverse effect was observed. Conclusion Hemocoagulase seems to be a safe and effective drug for severe HC following HSCT.

Bloqueio do receptor da interleucina-1 com anakinra inibe a cistite hemorrágica induzida por ifosfamida

Cistite hemorrágica (CH) induzida por ifosfamida (IFO) é uma importante complicação clínica em pacientes com câncer. Atualmente, mesna e hiper-hidratação são utilizadas como profilaxia, a despeito de ainda ser observada CH através de cistoscopia e histopatologia mesmo com essas medidas. A participação de interleucina-1 (IL-1) e fator de necrose tumoral (TNF) na patogênese da CH provê alvos para o tratamento dessa doença. Assim, esse trabalho objetivou avaliar o efeito protetor do antagonista do receptor da IL-1 (anakinra) e do anticorpo anti-TNF-alfa (infliximabe) nas respostas inflamatórias, nociceptivas e funcionais da CH experimental induzida por IFO em camundongos. Foram utilizados camundongos Swiss, C57BL6, IL-1R-/-, CASP1-/-, TNFR1-/-, TNFR1/R2-/-. Os animais WT foram submetidos ao tratamento com anakinra 100 mg/kg i.p. ou infliximabe 5 mg/kgi.p. ou salina i.p., foram tratados 1h após com IFO 400 mg/kg i.p., e 12 h após a IFO foi realizado o sacrifício, com excisão das bexigas para avaliaçãomacroscópica, histopatológica, permeabilidade vascular, mieloperoxidase, contratilidade, cistometrografia e citometria de fluxo para neutrófilos e macrófagos. Alguns animais, antes do sacrifício, foram submetidos a avaliação de nocicepção visceral. Anakinra foi capaz de atenuar hemorragia, edema, infiltrado neutrofílico, hipernocicepção visceral e disfunção vesical...

Hemorrhagic cystitis (HC) induced by ifosfamide (IFO) is an importantclinical complication in patients with cancer. Despite prophylaxis, HC isobserved. The role of interleukin-1 (IL-1) and tumor necrosis factor (TNF) in the pathogenesis of HC provides targets for treatment. Thus, this study aimed to evaluate the protective effect of the IL-1 receptor antagonist (anakinra) and anti-TNF-alpha antibody (infliximab) in experimental HC-induced by IFO in mice. Swiss , C57BL6 , IL -1R-/-, CASP1-/-, TNFR1-/-, TNFR1/R2-/-mice were used. Animals were submitted to pre-treatment with anakinra 100 mg/ kg, ip or infliximab 5 mg/ Kg, ip, or saline ip, 1h after, they were treated with IFO 400 mg/ kg ip, and 12 h after IFO injection they were killed. Then, it was performed resection of the bladder for macroscopic and histopathological evaluation, vascular permeability assay, myeloperoxidase assay, muscle contractility, cistometrogram and flow cytometry to neutrophils andmacrophages. Some animals prior to death, were subjected to evaluation of visceral nociception. Anakinra was able to attenuate hemorrhage, edema, neutrophil infiltration, visceral hypernociception and bladder dysfunction...

Clinical observation of 21 cases of unrelated donor hematopoietic stem cell transplantation for leukemia / 西安交通大学学报(医学版)

non-myeloablative BuCy+fludarabine conditioning regimen,and another one was treated with TBI+VP-1 6 +CTX+CCNU conditioning regimen.Only one case received short-term MTX,cyclosporin A and ATG regimen for prevention of graft-versus-host disease (GVHD).The GVHD prevention regimens of the other patients were based on short-term MTX,cyclosporin A,ATG and mycophenolate mofetil regimen.The hematopoietic reconstitution, complications and prognosis were observed.Results One patient died of intracranial hemorrhage,and hematopoi-etic reconstitution was achieved in the other 20 patients.The median time for hematopoietic reconstitution shortened by one day in large-dose group compared with that in low-dose group.Adverse reactions included high fever, shivering,gastrointestinal tract adverse reaction,liver injury,oral mucositis and other rare side effects.GVHD occurred more frequently in patients with HLA mismatched transplantation.Nine patients with aGVHD and 9 patients with cGVHD recovered after effective treatment.Within 100 days after transplantation,18 patients had bacterial or fungal infection,mainly upper respiratory tract infection;7 patients had cytomegalovirus infection;2 had EB viremia,and one had urinary BK virus infection.Only one patient died of VOD.Hemorrhagic cystitis occurred in 5 patients and improved after treatment.The median survival time was 24 months (ranging from 136 days to 9 years).One-year and 3-year overall survival rates were 85.2% and 63.9%,the disease free survival rates were 81% and 23.8%,recurrence free survival rates were 71.4% and 14.3%,respectively.Conclusion URD-HSCT was an effective method to treat leukemia.Conditioning regimen of BuCy and modified BuCy2 were safe and effective,the adverse reactions were reversible and well tolerated.Hematopoietic reconstitution time shortened in large-dose MNC and CD34 + cell number groups compared with that in low-dose group.The occurrence rate of GVHD with HLA mismatched transplantation was more than that of HLA matched transplantation.Low-dose heparin,prostaglandin E1 and Danshen injection can effectively prevent VOD.

Treatment of BK virus-associated hemorrhagic cystitis with low-dose intravenous cidofovir in patients undergoing allogeneic hematopoietic cell transplantation

BACKGROUND/AIMS: BK virus (BKV) has been associated with late-onset hemorrhagic cystitis (HC) in recipients of hematopoietic stem cell transplantation (HSCT). Cidofovir has been used at higher doses (3 to 5 mg/kg/wk) with probenecid prophylaxis; however, cidofovir may result in nephrotoxicity or cytopenia at high doses. METHODS: Allogeneic HSCT recipients with BKV-associated HC are treated with 1 mg/kg intravenous cidofovir weekly at our institution. A microbiological response was defined as at least a one log reduction in urinary BKV viral load, and a clinical response was defined as improvement in symptoms and stability or reduction in cystitis grade. RESULTS: Eight patients received a median of 4 weekly (range, 2 to 11) doses of cidofovir. HC occurred a median 69 days (range, 16 to 311) after allogeneic HSCT. A clinical response was detected in 7/8 patients (86%), and 4/5 (80%) had a measurable microbiological response. One patient died of uncontrolled graft-versus-host disease; therefore, we could not measure the clinical response to HC treatment. One microbiological non-responder had a stable BKV viral load with clinical improvement. Only three patients showed transient grade 2 serum creatinine toxicities, which resolved after completion of concomitant calcineurin inhibitor treatment. CONCLUSIONS: Weekly intravenous low-dose cidofovir without probenecid appears to be a safe and effective treatment option for patients with BKV-associated HC.

Diallyl Disulfide Prevents Cyclophosphamide-Induced Hemorrhagic Cystitis in Rats through the Inhibition of Oxidative Damage, MAPKs, and NF-kappaB Pathways

This study investigated the possible effects and molecular mechanisms of diallyl disulfide (DADS) against cyclophosphamide (CP)-induced hemorrhagic cystitis (HC) in rats. Inflammation response was assessed by histopathology and serum cytokines levels. We determined the protein expressions of nuclear transcription factor kappa-B (NF-kappaB), inducible nitric oxide synthase (iNOS), cyclooxygenase-2 (COX-2), and tumor necrosis factor-alpha (TNF-alpha), oxidative stress, urinary nitrite-nitrate, malondialdehyde (MDA), and 8-hydroxy-2'-deoxyguanosine (8-OHdG). Finally, we studied the involvement of mitogen-activated protein kinases (MAPKs) signaling in the protective effects of DADS against CP-induced HC. CP treatment caused a HC which was evidenced by an increase in histopathological changes, proinflammatory cytokines levels, urinary nitrite-nitrate level, and the protein expression of NF-kappaB, COX-2, iNOS, TNF-alpha, p-c-Jun N-terminal kinase (JNK), and p-extracellular signal regulated kinase (ERK). The significant decreases in glutathione content and glutathione-S-transferase and glutathione reductase activities, and the significant increase in MDA content and urinary MDA and 8-OHdG levels indicated that CP-induced bladder injury was mediated through oxidative DNA damage. In contrast, DADS pretreatment attenuated CP-induced HC, including histopathological lesion, serum cytokines levels, oxidative damage, and urinary oxidative DNA damage. DADS also caused significantly decreased the protein expressions of NF-kappaB, COX-2, iNOS, TNF-alpha, p-JNK, and p-ERK. These results indicate that DADS prevents CP-induced HC and that the protective effects of DADS may be due to its ability to regulate proinflammatory cytokines production by inhibition of NF-kappaB and MAPKs expressions, and its potent anti-oxidative capability through reduction of oxidative DNA damage in the bladder.

Hemorrhagic Cystitis with Giant Cells in Rheumatoid Arthritis Treating with Tacrolimus

Hemorrhagic cystitis is a diffuse inflammation of the mucosa of the bladder, characterized by hematuria and burning upon urination. This might be caused by a variety of reasons, including undergoing chemotherapy (such as cyclophosphamide), radiation therapy, bladder cancer, certain viruses, urinary infections, and thrombocytopenia. There are no previous reports of hemorrhagic cystitis associated with the use of tacrolimus. This is the first case of hemorrhagic cystitis due to tacrolimus for the treatment of rheumatoid arthritis. We describe a case of hemorrhagic cystitis with giant cells in a patient with rheumatoid arthritis treating with tacrolimus. Hematuria resolved spontaneously with discontinuation of the drug.

Gender mismatch, use of anti-thymoglobulin, and occurrence of graft-versus-host disease in preparative regimen are associated with high incidence of post-engraftment hemorrhagic cystitis in allogeneic hematopoietic stem cell transplantation / 白血病·淋巴瘤

Objective To evaluate the risk factors of developing post-engraftment hemorrhagic cystitis (HC) in patients receiving allogeneic stem cell transplantation (allo-HSCT).Methods Retrospective data was collected from 92 patients with acute leukemia (acute myeloid leukemia 41 and acute lymphoblastic leukemia 51) who underwent allo-HSCT from 2000 to 2010,and the association of pre-transplantation parameters with the incidence of post-engraftment HC was analyzed.Results Forty-three patients had HLA-matched donors and 49 had unrelated donors.Of these patients,25 developed HC at a median of 35 days (day +20 to +65) after allo-HSCT.In the univariate analysis,unrelated donor,gender mismatch (female donor to male recipient),conditioning containing busulfan,graft-versus-host disease (GVHD),prophylaxis with cyclosporine (CSA) + methotrexate (MTX) + mycophenolate mofetil (MMF),use of anti-thymoglobulin (ATG) and development of GVHD were associated with increased incidence of HC.In the multivariate study,gender mismatch (P =0.001),use of ATG (P ＜ 0.001),and GVHD (P =0.007) remain as independent factors for the increased risk of HC.More importantly,with these 3 factors,it is able to classify patients into 4 groups with risk of postengraftment HC at (7.7±4.6) ％,(22.9±7.1) ％,(48.2±10.5) ％,and 100.0 ％,respectively.Conclusion This retrospective study identified the gender mismatch,use of ATG in the preparation regimen,and aGVHD as important risk factors to predict the development of post-engraftment HC.Based on these risk factors,it is possible to classify patients into different risk groups for post-engraftment HC.Prospective study with a large cohort of patients is warranted to confirm the findings.Future clinical trial for HC prevention and treatment must be carried out on the intermediate and high-risk patients.

Hemorrhagic cystitis with massive bleeding from nontyphoidal Salmonella infection: A case report

Hemorrhagic cystitis is defined by lower urinary tract symptoms that include dysuria, hematuria, and hemorrhage and is caused by viral or bacterial infection or chemotherapeutic agents. Reports of hemorrhagic cystitis caused by non-typhoidal salmonella (NTS) are extremely rare. We report a case of a 41-year-old man with hemorrhagic cystitis from NTS that caused massive bleeding and shock. The patient was hospitalized for uncontrolled diabetes and obstructive uropathy related to severe cystitis. A urine culture was positive for group D NTS. This case demonstrated that hemorrhagic cystitis in a patient with a risk factor such as diabetes can be a manifestation of local extraintestinal NTS infection.

A Case of Intravesical Cidofovir Treatment of BK Virus-Associated Hemorrhagic Cystitis after Allogeneic Peripheral Blood Stem Cell Transplantation / 영남의대학술지

Hemorrhagic cystitis (HC) is a common complication after allogeneic transplantation. Early posttransplant HC occurs in association with cyclophosphamide, while later on HC results from viral infections such as polyomavirus BK (BKV) and adenovirus. We report here the case of a 57-year-old woman who received an instillation of cidofovir into the bladder for the treatment of hemorrhagic cystitis after allogeneic peripheral stem cell transplantation for her acute myeloid leukemia. Cyclophosphamide and busulfan were used as conditioning treatments. Cyclosporin was administered daily. On the 71st day after transplantation, the patient developed acute severe hemorrhagic cystitis, and BK virus was demonstrated in the urine samples using polymerase chain reaction. Her urinary symptoms did not improve in spite of palliative treatment, but a response was evident after intravesical cidofovir treatment.

Risk Factors of Hemorrhagic Cystitis after Allogeneic Stem Cell Transplantation / 대한혈액학회지

BACKGROUND: Hemorrhagic cystitis (HC) is one of major causes of morbidity during hematopoietic stem cell transplantation (HSCT), occurring in 7~52% of transplant recipients. We have analyzed the incidence, risk factors, and complications of early ( or = grade II) with urinary obstruction and renal failure (n=2). One patient with grade IV HC died of pneumonia associated with persistent HC. Early and late- onset HC developed at median 9 (2~20) and 55 (31~100) days post-transplant, respectively. Median duration of HC was 16 (3~153) days. Of 23 evaluable patients for study in urine, BK virus was detected in 52% by culture and in 61% by PCR, whereas adenovirus in 18% by PCR. By univariate analysis, disease of aplastic anemia (P=0.03) and non-use of radiation in conditioning regimen (P=0.003) were risk factors for early-onset HC, while the use of busulfan in conditioning regimen (P= 0.02) and grade II-IV acute graft-versus-host disease (GVHD) (P=0.00001) for late-onset HC. By multivariate analysis, use of busulfan (RR=16.62, P=0.002) and aplastic anemia than other disease (RR=9.6, P=0.008) were unfavorable factor for early-onset HC, as only grade II-IV acute GVHD (RR=6, P=0.001) for late- onset HC. CONCLUSION: More than half of patients with HC developed after allogeneic HSCT were associated with urinary excretion of BK virus. Because of HC is one of the important causes of morbidity after allogeneic HSCT, special attention should be paid to attempting the prevention of HC in patients with high-risk for the development of HC.
