ABSTRACT
Objective: To investigate whether haplotype hematopoietic stem cell transplantation (haplo-HSCT) is effective in the treatment of pre transplant minimal residual disease (Pre-MRD) positive acute B lymphoblastic leukemia (B-ALL) compared with HLA- matched sibling donor transplantation (MSDT) . Methods: A total of 998 patients with B-ALL in complete remission pre-HSCT who either received haplo-HSCT (n=788) or underwent MSDT (n=210) were retrospectively analyzed. The pre-transplantation leukemia burden was evaluated according to Pre-MRD determinedusing multiparameter flow cytometry (MFC) . Results: Of these patients, 997 (99.9% ) achieved sustained, full donor chimerism. The 100-day cumulative incidences of neutrophil engraftment, platelet engraftment, and grades Ⅱ-Ⅳ acute graft-versus-host disease (GVHD) were 99.9% (997/998) , 95.3% (951/998) , and 26.6% (95% CI 23.8% -29.4% ) , respectively. The 3-year cumulative incidence of total chronic GVHD was 49.1% (95% CI 45.7% -52.4% ) . The 3-year cumulative incidence of relapse (CIR) and non-relapse mortality (NRM) of the 998 cases were 17.3% (95% CI 15.0% -19.7% ) and 13.8% (95% CI 11.6% -16.0% ) , respectively. The 3-year probabilities of leukemia-free survival (LFS) and overall survival (OS) were 69.1% (95% CI 66.1% -72.1% ) and 73.0% (95% CI 70.2% -75.8% ) , respectively. In the total patient group, cases with positive Pre-MRD (n=282) experienced significantly higher CIR than that of subjects with negative Pre-MRD [n=716, 31.6% (95% CI 25.8% -37.5% ) vs 14.3% (95% CI 11.4% -17.2% ) , P<0.001]. For patients in the positive Pre-MRD subgroup, cases treated with haplo-HSCT (n=219) had a lower 3-year CIR than that of cases who underwent MSDT [n=63, 27.2% (95% CI 21.0% -33.4% ) vs 47.0% (95% CI 33.8% -60.2% ) , P=0.002]. The total 998 cases were classified as five subgroups, including cases with negative Pre-MRD group (n=716) , cases with Pre-MRD<0.01% group (n=46) , cases with Pre-MRD 0.01% -<0.1% group (n=117) , cases with Pre-MRD 0.1% -<1% group (n=87) , and cases with Pre-MRD≥1% group (n=32) . For subjects in the Pre-MRD<0.01% group, haplo-HSCT (n=40) had a lower CIR than that of MSDT [n=6, 10.0% (95% CI 0.4% -19.6% ) vs 32.3% (95% CI 0% -69.9% ) , P=0.017]. For patients in the Pre-MRD 0.01% -<0.1% group, haplo-HSCT (n=81) also had a lower 3-year CIR than that of MSDT [n=36, 20.4% (95% CI 10.4% -30.4% ) vs 47.0% (95% CI 29.2% -64.8% ) , P=0.004]. In the other three subgroups, the 3-year CIR was comparable between patients who underwent haplo-HSCT and those received MSDT. A subgroup analysis of patients with Pre-MRD<0.1% (n=163) was performed, the results showed that cases received haplo-HSCT (n=121) experienced lower 3-year CIR [16.0% (95% CI 9.4% -22.7% ) vs 40.5% (95% CI 25.2% -55.8% ) , P<0.001], better 3-year LFS [78.2% (95% CI 70.6% -85.8% ) vs 47.6% (95% CI 32.2% -63.0% ) , P<0.001] and OS [80.5% (95% CI 73.1% -87.9% ) vs 54.6% (95% CI 39.2% -70.0% ) , P<0.001] than those of MSDT (n=42) , but comparable in 3-year NRM [5.8% (95% CI 1.6% -10.0% ) vs 11.9% (95% CI 2.0% -21.8% ) , P=0.188]. Multivariate analysis showed that haplo-HSCT was associated with lower CIR (HR=0.248, 95% CI 0.131-0.472, P<0.001) , and superior LFS (HR=0.275, 95% CI 0.157-0.483, P<0.001) and OS (HR=0.286, 95% CI 0.159-0.513, P<0.001) . Conclusion: Haplo HSCT has a survival advantage over MSDT in the treatment of B-ALL patients with pre MRD<0.1% .

Objective: To evaluate the efficacy and safety of autologous hematopoietic stem cell transplantation (auto-HSCT) in elderly patients (≥65 years old) with multiple myeloma (MM) . Methods: From June 1, 2006 to July 31, 2020, 22 MM patients (≥65 years old) who were diagnosed in the First Affiliated Hospital, Sun Yat-sen University and received novel drug induction followed by auto-HSCT were analyzed retrospectively. These patients were evaluated for important organ functions before transplantation, and the International Myeloma Working Group frail score was used in 2016 to screen out transplant-eligible patients. Results: The median (interquartile range, IQR) age at the time of transplantation of the 22 patients was 66.75 (IQR 4.50) years. A total of 20 patients received stem cell mobilization. The median number of mononuclear cells collected was 4.53×10(8)/kg, that of CD34(+) cells was 3.37×10(6)/kg, and the median number of apheresis procedures performed was 2. After stem cell transfusion, the median time of neutrophil implantation was 11 days, that of platelet implantation was 13 days, and the treatment-related mortality was 0 at 100 days after transplantation. The median follow-up was 48.7 months. The median time to progression time was not reached, and the median overall survival time was 111.8 months. Conclusion: Auto-HSCT is a safe and effective treatment for selected elderly patients of 65 years or older with MM.

Objective: To evaluate the efficacy and prognosis of basiliximab in the treatment of steroid-refractory or steroid-dependent acute graft-versus-host disease (SR/SD-aGVHD) after allogeneic hematopoietic stem cell transplantation (allo-HSCT) . Methods: Clinical data of 87 patients with SR/SD-aGVHD in the skin, intestine, and liver after allo-HSCT at the Institute of Hematology & Blood Diseases Hospital Transplantation Center from January 2015 to December 2018 were retrospectively analyzed. The administration plan of basiliximab was as follows: 20 mg for adults and children weighing ≥35 kg and 10 mg for children weighing<35 kg. The drug was administered once on the 1st, 4th, and 8th days, respectively, and then once weekly. The efficacy was evaluated on the 7th, 14th, 21st, and 28th days after basiliximab treatment. Results: ①There were 51 males (58.6%) and 36 females (41.4%) , with a median (range) age of 34 (4-63) years. There were 54 cases of classic aGVHD, 33 of late aGVHD, 49 of steroid-refractory aGVHD, and 38 of steroid-dependent aGVHD. ②Thirty-five patients (40.2%) achieved complete remission (CR) , 23 (26.4%) achieved partial remission (PR) , and 29 had no remission (NR) . The total effective rate[overall response rate (ORR) ] was 66.7% (58/87) . ③The ORR of the classic and late aGVHD groups was 77.8% (42/54) and 48.5% (16/33) , respectively. ④The median (range) follow-up time was 154 (4-1813) days, the 6-month overall survival (OS) rate of the 87 patients was 44.8% (95% CI 39.5%-50.1%) and the 1-year OS was 39.4% (95%CI 34.2%-44.3%) . ⑤After treatment with basiliximab, the 6-month OS in the CR (35 cases) , PR (23 cases) , and NR (29 cases) groups was 80.0% (95%CI 73.2%-86.8%) , 39.1% (95%CI 28.9%-49.3%) , and 6.9% (95%CI 2.2%-11.6%) , respectively (χ(2)=34.679, P<0.001) , and the 1-year OS was 74.3% (95%CI 66.9%-81.7%) , 30.4% (95%CI 20.8%-40.0%) , and 3.4% (95%CI 0%-6.8%) , respectively (χ(2)=43.339, P<0.001) . The OS of the classic and late aGVHD groups was 57.4% (95%CI 50.7%-64.1%) and 24.2% (95%CI 16.7%-31.7%) , respectively (χ(2)=9.109, P=0.004) , and the 1-year OS was 51.9% (95%CI 45.1%-58.7%) and 18.2% (95%CI 11.5%-24.9%) , respectively (χ(2)=9.753, P=0.003) . ⑥Univariate and multivariate analyses showed that late aGVHD (OR=3.121, 95%CI 1.770-5.503, P<0.001) , Minnesota score high-risk group before medication (OR=3.591, 95%CI 1.931-6.679, P<0.001) , active infection before medication (OR=1.881, 95%CI 1.029-3.438, P=0.040) , and impairment of important organ function caused by non-GVHD (OR=3.100, 95%CI 1.570-6.121, P=0.001) were independent risk factors affecting the efficacy of basiliximab. Conclusion: Basiliximab has good efficacy and safety for SR/SD-aGVHD, but not in patients with late aGVHD, high-risk group of Minnesota score, and infection or impaired function of important organs.

Coronavirus disease 2019 (COVID-19) has spread rapidly worldwide since outbreak in December 2019, and become a global public health crisis. Patients with hematological malignancy concurrently infected with COVID-19 are often associated with severe even fatal complications, due to low basic immune function, high intensity of chemotherapy and radiotherapy, and slow immune reconstruction post hematopoietic stem cell transplantation, and their treatment strategies, such as anti-infective therapy, blood transfusion, and the use of granulocyte colony stimulating factor need to be adjusted. The characteristics of patients, chemotherapy, hematopoietic stem cell transplantation, and other clinical factors may affect the prognosis of patients with hematological malignancy concurrently infected with COVID-19. Herein, the latest research progress is reviewed.

OBJECTIVE@#To observe the clinical characteristics, treatment and prognosis of intestinal acute graft-versus-host disease (aGVHD) after allogeneic hematopoietic stem cell transplantation (allo-HSCT) in children and futher evaluate the occurring risk factors.@*METHODS@#The clinical data of 136 patients undergoing allo-HSCT in Wuhan Children's Hospital Affiliated to Tongji Medical College from August 2016 to August 2020 were retrospectively analyzed, clinical characteristics of children with intestinal aGVHD were observed. The risk factors of intestinal aGVHD were assessed by logistic regression while cumulative survival were analyzed by Kaplan-Meier method.@*RESULTS@#Among 136 patients intestinal aGVHD occurred in 24 (17.6%) cases, with 4 cases of grade II, 20 cases of grade III-IV, and the median occurrence time was 28(10-63) days. The clinical manifestations were diarrhea with intermittent abdominal pain, 17 cases with nausea and vomiting, 11 cases with fresh bloody stool, and 8 cases with skin rash before intestinal aGVHD. The average time for treatment was 33(11-100) days. 18 cases received electronic colonoscopy and histopathology examination. 20 out of 24 cases achieved remission after treatment, and the total effective rate was 83.3%. Finally, 9 out of 24 cases died during the follow-up time. Survival analysis showed that the cumulative survival rate of patients with intestinal aGVHD (15/24, 62.5%) were significantly lower than those without intestinal aGVHD (101/112, 90.2%) (Log-rank test, P=0.001). Univariate analysis showed that recipient age, sex, primary disease, donor age, donor sex, donor-recipient blood type, conditioning regimen, prophylaxis of GVHD, dosage of ATG, engraft time of blood platelet and neutrophils, and number of MNC/CD34+ were not risk factors for intestinal aGVHD (P>0.05). Only the type of HSCT (χ2=16.020, P=0.001) and matched degree of HLA (χ2=15.502, P=0.001) had statistical significance with intestinal aGVHD (P<0.05). Multivariate analysis showed that only HLA-mismatched unrelated donor was the risk factor for intestinal aGVHD for children (P=0.014，OR=16，95%CI 1.735-147.543).@*CONCLUSION@#Intestinal aGVHD is a risk factor for cumulative survial of patients who received allo-HSCT in children and HLA-mismatched unrelated donor is its independent risk factor.

Objective: To investigate the characteristics, risk factors and outcomes of thalassemia major (TM) children with pericardial effusion (PE) after allo-geneic hematopoietic stem cell transplantation (allo-HSCT). Methods: Clinical data of 446 TM children received allo-HSCT at Shenzhen Children's Hospital between January 2012 and December 2020 were analyzed retrospectively. Patients were divided into PE and non-PE group according to the occurrence of PE. Chi-square tests were used to investigate the risk factors that were associated with the development of PE. Kaplan-Meier method was used for survival analysis of the 2 groups. Results: Twenty-five out of 446 patients (5.6%) developed PE at a time of 75.0 (66.5, 112.5) days after allo-HSCT. Among these patients, 22 cases (88.0%) had PE within 6 months after allo-HSCT and 19 patients (76.0%) had PE within 100 days after allo-HSCT. The diagnoses of PE were confirmed using echocardiography. Pericardial tamponade was observed in only 1 patient, who later undergone emergency pericardiocentesis. The rest of patients received conservative managements alone. PE disappeared in all patients after treatment. Risk factors that were associated with the development of PE after allo-HSCT included the gender of patients, the type of transplantation, the number of mononuclear cells (MNC) infuse, pulmonary infection after HSCT and transplantation associated thrombotic microangiopathy (TA-TMA) (χ²=3.99, 10.20, 14.18, 36.24, 15.03, all P<0.05). In 239 patients that received haploidentical HSCT, the development of PE was associated with the gender of patients, pulmonary infection after HSCT and TA-TMA (χ²=4.48, 20.89, 12.70, all P<0.05). The overall survival rates of PE and non-PE groups were 96.0% (24/25) and 98.6% (415/421). The development of PE was not associated with the overall survival of TM children after allo-HSCT (χ²=1.73, P=0.188). Conclusions: PE mainly develop within 100 days after allo-HSCT in pediatric TM recipients. Haploidentical grafts, female gender, pulmonary infection after HSCT and TA-TMA are the main risk factors associated with PE development after transplant. However, the presence of PE don't have a significant impact on the outcomes of pediatric TM patients after allo-HSCT.

El diagnóstico diferencial entre la enfermedad de injerto contra huésped aguda grave (estadio IV) y la necrólisis epidérmica tóxica pude resultar difícil en el contexto de un paciente trasplantado, ya que ambas tienen presentaciones clínicas similares. Sin embargo, la distinción entre ellas es fundamental porque ocasionan una gran morbimortalidad, y su manejo y pronóstico difieren. Algunas pequeñas diferencias clínicas e histopatológicas son de gran ayuda para el diagnóstico diferencial y el dermatólogo deberá reconocerlas para tomar una conducta correcta y oportuna. Se comunica el caso de un paciente que presentó ampollas y epidermólisis después del trasplante de células hematopoyéticas y en el que se planteó la dificultad diagnóstica para diferenciar entre ambas afecciones.
The differental diagnosis between severe graft-versus-host disease (stage IV) and toxic epidermal necrolysis can be difficult in the context of a transplant patient, since both conditions have similar clinical presentations. However, the distinction between these two entities is critical because they produce great morbidity and mortality and their management and prognosis differ. Some small clinical and histopathological differences are of great help for the differential diagnosis, and the dermatologist must recognize them in order to take a correct and timely conduct. We present the case of a patient who developed blisters and epidermolysis after hematopoietic cell transplantation, and in whom the diagnostic difficulty to differentiate between the two entities was raised.

Introducción: El trasplante de células progenitoras hematopoyéticas (TPH) en niños es un procedimiento no exento de complicaciones graves. El ingreso de esta población a unidades de cuidados intensivos pediátricos (UCIP) se asocia con elevada mortalidad. Objetivos: Analizar la sobrevida y los factores predictivos de la mortalidad en niños que recibieron TPH e ingresaron a la UCIP y elaborar un modelo predictivo de mortalidad en esta población. Materiales y métodos: Revisión retrospectiva de niños y adolescentes que recibieron un TPH entre el 01/01/2005 y el 31/12/2019 e ingresaron a la UCIP de un hospital universitario de alta complejidad. Resultados: De un total de 264 niños que recibieron el trasplante, 114 ingresaron a la UCIP. La mortalidad general fue del 29 % (n = 34). El tipo de trasplante, enfermedad basal, evento de neutropenia febril, infección por citomegalovirus, insuficiencia respiratoria, enfermedad de injerto contra huésped (EICH), quimioterapia mieloablativa y desnutrición previa se asociaron con tasas de mortalidad más elevadas. En el análisis multivariado, la EICH (razón de posibilidades [OR, por su sigla en inglés]: 2,23; intervalo de confianza del 95 % [IC 95 %]: 1,92-2,98), la necesidad de ventilación mecánica invasiva (OR: 2,47; IC95 %: 1,39-5,73), el trasplante de donante alternativo (OR: 1,58; IC 95 %: 1,14-2,17) y la desnutrición previa (OR: 1,78; IC 95 %: 1,223-3,89) se asociaron con mayor mortalidad. Conclusión: En la población estudiada, dos de cada tres niños que recibieron TPH e ingresaron a la UCIP sobrevivieron. La EICH, ventilación mecánica, trasplante de donante alternativo y desnutrición previa fueron factores predictivos de mortalidad
Introduction: Hematopoietic stem cell transplantation (HSCT) in children is a procedure that is not exempt of severe complications. Admission to the pediatric intensive care unit (PICU) is associated with a high mortality rate. Objectives: To analyze survival and predictors of mortality among children who received a HSCT and were admitted to the PICU, and to develop a mortality prediction model in this population. Materials and methods: Retrospective review of children and adolescents who received a HSCT between January 1st, 2005 and December 31st, 2019 and were admitted to the PICU of a tertiary care teaching hospital. Results: Out of 264 children receiving the transplant 114 were admitted to the PICU. The overall mortality rate was 29 % (n = 34). The type of transplant, underlying disease, febrile neutropenia event, cytomegalovirus infection, respiratory failure, graft versus host disease (GVHD), myeloablative chemotherapy, and previous malnutrition were associated with higher mortality rates. In the multivariate analysis, GVHD (odds ratio [OR]: 2.23; 95 % confidence interval [CI]: 1.92-2.98), need for mechanical ventilation (OR: 2.47; 95 % CI: 1.39-5.73), alternative donor transplant (OR: 1.58; 95 % CI: 1.14-2.17), and previous malnutrition (OR: 1.78; 95 % CI: 1.22-3.89) were associated with a higher mortality rate. Conclusion: In the studied population, 2 out of 3 children who received a HSCT and were admitted to the PICU survived. GVHD, mechanical ventilation, alternative donor transplant, and previous malnutrition were predictors of mortality

Resumen Las infecciones fúngicas invasoras (IFI) constituyen una de las principales complicaciones infecciosas en pacientes oncohematológicos y con trasplante de células progenitoras hematopoyéticas (TCPH), ocasionando alta morbimortalidad e incrementando significativamente los costos de atención y la estadía hos pitalaria. La epidemiología de las IFI ha cambiado en las últimas décadas, siendo los hongos filamentosos, particularmente Aspergillus spp., los principales agentes etiológicos. Existen múltiples factores de riesgo para una IFI; pero la neutropenia profunda y prolongada, y la inmunodeficiencia celular severa siguen siendo los más importantes. Por este motivo, la población de mayor riesgo la constituyen los pacientes con leucemias agudas, mielodisplasias y TCPH alogénicos con enfermedad injerto contra huésped (EICH), en tratamiento con corticoides. Numerosos ensayos clínicos aleatorizados y metaanálisis han demostrado que la profilaxis antifúngica primaria (PAF) reduce significativamente la incidencia de IFI, tanto de aquellas causadas por Candida spp. como por Aspergillus spp., la mortalidad relacionada a IFI y la mortalidad global en algunos grupos de pacientes. Asimismo, en enfermos de alto riesgo, en donde se espera una incidencia de IFI elevada, es una estrategia costo-efectiva. Varios antifúngicos han demostrado beneficio clínico y pueden utilizarse como estrategia de PAF en diferentes escenarios, presentando ventajas y desventajas que deben ser tenidas en cuenta al momento de indicar una PAF. Para esto, sociedades científicas nacionales e internacionales, han emitido recomendaciones de indicación de PAF. Se analizan los aspectos relacionados con la eficacia clínica de los diferentes antifúngicos según la población de riesgo, las potenciales desventajas, momento y forma de administración.
Abstract Invasive fungal infections (IFI) are among the main infectious complications in patients with hema tological malignancies and with hematopoietic stem cell transplant (HSCT), causing high morbidity and mortality and significantly increasing the healthcare cost and hospital stay. The epidemiology of IFIs has changed in recent decades, with filamentous fungi, particularly Aspergillus spp., being the main etiological agents. There are multiple risk factors for having an IFI; however, the most important are profound and prolonged neutropenia and severe cellular immunodeficiency. For this reason, the population at greatest risk is made up of patients with acute leukemias, myelodysplasias and allogeneic HSCT with graft-versus-host disease (GVHD) treated with cortico steroids. Numerous randomized clinical trials and meta-analyses have shown that primary antifungal prophylaxis (AFP) significantly reduces the incidence of IFI, particularly those caused by Candida spp. and Aspergillus spp., IFI-related mortality, and overall mortality in some group of patients. Likewise, in high-risk patients, where a high incidence of IFI is expected, it is a cost-effective strategy. Several antifungals have demonstrated clinical benefit. They can be used as a AFP strategy in different settings, presenting advantages and disadvantages that must be taken into account in each case. For this, national and international scientific societies have issued recom mendations for the indication of AFP. Aspects related to the different antifungals' clinical efficacy are analyzed considering the population at risk, the potential disadvantages, timing, and form of administration.

Introducción: La infección por citomegalovirus es muy frecuente en pacientes sometidos a trasplante de progenitores hematopoyéticos, debido a tratamientos mieloablativos de acondicionamiento, disparidad genética y al tratamiento inmunosupresor, y ocurre fundamentalmente después de la toma del implante. Objetivos: Actualizar el diagnóstico, manejo y seguimiento de la infección por citomegalovirus en pacientes trasplantados. Métodos: Se realizó revisión bibliográfica en los idiomas español e inglés, utilizando los motores de búsqueda de Pubmed, Google Académico y Scielo sobre el diagnóstico y manejo del citomegalovirus en pacientes receptores de trasplante hematopoyético. Análisis y síntesis de la información: Se recolectó y organizó la información obtenida siguiendo cronológicamente el surgimiento de técnicas para diagnóstico y la aparición de nuevos medicamentos en los últimos años. Se seleccionaron artículos recientes de expertos en el tema en revistas prestigiosas, donde se evidencia la importancia del diagnóstico adelantado y el inicio del tratamiento. Conclusiones: En la actualidad se cuenta con nuevas formas de diagnóstico y medicamentos novedosos para el citomegalovirus, pero la mortalidad puede llegar a ser alta, si el paciente no es tratado antes de que aparezcan los síntomas de la enfermedad e incluso a pesar del tratamiento. En ocasiones, no es posible erradicar el virus, lo que lleva a complicaciones importantes y a la muerte. La enfermedad citomegálica continúa siendo una complicación frecuente en estos pacientes a pesar de las medidas para evitar su reactivación(AU)
Introduction: Cytomegalovirus infection is very common in patients undergoing hematopoietic progenitor transplantation, due to myeloablative conditioning treatments, genetic disparity, and immunosuppressive treatment, and occurs mainly after the engrafment. Objective: A review and update of the diagnosis and management of cytomegalovirus is made in hematopoietic transplant recipients. Method: A bibliographic review was carried out in Spanish and English, using the search engines of Pubmed, Scholar Google and Scielo about the diagnosis and management of cytomegalovirus in hematopoietic transplant recipients. Development: The information obtained was collected and organized chronologically about the emergence of techniques for diagnosis and the appearance of new drugs in recent years. Recent articles by experts in prestigious journals were reviewed and the importance of early diagnosis and initiation of treatment is evidenced. Conclusions: There are currently new forms of diagnosis and novel medications, but mortality can be high, if the patient is not treated before the symptoms of the disease appear and even despite treatment, sometimes it is not possible to eradicate the virus, leading to major complications and death. Cytomegalic disease continues to be a frequent complication in these patients despite measures to prevent virus reactivation(AU)

Abstract Chagas disease (CD) is a protozoan zoonosis caused by Trypanosoma cruzi. Reactivation of CD occurs via drug-induced immunosuppression before and during transplantation. Here, we report the case of a 62-year-old man diagnosed with classic Hodgkin lymphoma who received highly aggressive conditioning chemotherapy before undergoing stem cell transplantation (SCT). The patient tested positive for CD in pre-transplantation evaluation. The patient exhibited persistent fever and elevated C-reactive protein levels before and after SCT, and was treated with antibiotics. Micro-Strout test showed evidence of trypomastigotes and he was treated with benznidazole until tested negative. Post-transplantation seropositive patients should be screened for possible reactivation.

BACKGROUND@#The impacts of previous cardio-cerebrovascular disease (pre-CCVD) on the outcomes of hematopoietic cell transplantation (HCT) are not well described. Patients with pre-CCVD may often be poor candidates for HCT. This study aimed to investigate the impact of pre-CCVD on transplant outcomes.@*METHODS@#A retrospective study was conducted between patients with and without pre-CCVD who consecutively received allogeneic or autologous HCT between November 2013 and January 2020 with a matching of age and disease status. The cardiovascular complications and HCT outcomes of the two groups were evaluated and compared. The primary endpoints were post-transplant cardio-cerebrovascular disease (post-CCVD) and non-relapse mortality (NRM). We used a multivariable Cox proportional hazard model and the Fine-Gray competing risk regressions for analyses to estimate the hazard ratios (HRs).@*RESULTS@#The outcomes of 23 HCT recipients with pre-CCVD were compared with those of 107 patients in the control group. No significant differences were noted in terms of engraftment, overall survival (OS) (67.00% vs. 67.90%, P = 0.983), or relapse (29.78% vs. 28.26%, P = 0.561) between the pre-CCVD group and the control group. The cumulative incidences of 2-year NRM were similar between patients with pre-CCVD and the controls (14.68% vs. 17.08%, P = 0.670). However, pre-CCVD was associated with an increased incidence of post-CCVD (HR: 12.50, 95% confidence interval [CI]: 3.88-40.30, P < 0.001), which was an independent risk factor for increased NRM (HR: 10.29, 95% CI: 3.84-27.62, P < 0.001) and inferior OS (HR: 10.29, 95% CI: 3.84-27.62, P < 0.001).@*CONCLUSIONS@#These findings suggest that the existence of pre-CCVD before transplantation might not result in increased mortality directly but superpose the toxicity of the transplantation procedure, leading to a risk of post-CCVD. Post-CCVD was a powerful predictor for high NRM and inferior OS. Further risk stratification of pre-CCVD is needed to reduce NRM in various transplantation settings.

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.

Resumen Introducción: Los niños que reciben trasplante de precursores hematopoyéticos (TPH) pueden presentar infecciones respiratorias virales (IRV) durante episodios febriles. Los datos sobre su evolución clínica son escasos, así como la comparación de ellos con infecciones bacterianas (IB). Objetivo: Caracterizar la evolución clínica de pacientes con IRV, en comparación con IB en niños con TPH, cursando un episodio febril. Método: Estudio prospectivo en pacientes ≤ 18 años con cáncer y TPH ingresados por fiebre en el Hospital Luis Calvo Mackenna (2016-2019). Se realizó evaluación clínica y de laboratorio: hemocultivos, RPC para patógenos respiratorios (Filmarray®), cuantificación viral y medición de citoquinas en muestra nasal (Luminex®, 38 citoquinas). Se compararon los grupos IRV, IB y los de etiología no precisada (ENP) en relación con: infección respiratoria aguda (IRA), citoquinas nasales, ingreso a UCI, necesidad de ventilación mecánica, mortalidad y suspensión de antimicrobianos. Resultados: De 56 episodios febriles, 35 fueron IRV, 12 IB y 9 de ENP. Mediana de edad fue 8,5 años, 62% masculino. Un 94% de los casos IRV presentó IRA sintomática, versus 33% en los grupos IB y ENP (p < 0,001), con IRA baja en 69% de las IRV (p < 0,001). Rinovirus (54%) y coronavirus (15%) fueron las etiologías más frecuentemente detectadas. No hubo diferencias en citoquinas nasales entre los grupos IRV e IB. Ingreso a UCI: 11% del grupo IRV, 17% de IB y 11% de ENP (p = 0,88). Requirieron ventilación mecánica sólo 2 pacientes (p = 0,37) sin fallecimiento. Tras la detección viral respiratoria por RPC, se suspendió antimicrobianos en 26% de los casos con IRV (p = 0,04). Conclusión: Las IRV son frecuentes en niños con TPH y episodios febriles. La detección viral podría optimizar y racionalizar el uso de antimicrobianos en esta población.
Abstract Background: Children undergoing hematopoietic stem cell transplant (HSCT) can develop respiratory viral infections (RVI) during fever episodes. There are few data about clinical outcomes in RVI and compared to bacterial infections (BI) in this population. Aim: To determine clinical outcome of RVI, compared to BI in children with HSCT. Methods: Prospective study, patients ≤ 18 years with cancer and HSCT admitted with fever at a National Bone Marrow Transplant Center (Hospital Calvo Mackenna), Chile, (April-2016 to May-2019). Clinical assessment, laboratory tests, blood cultures, nasopharyngeal sample for multiplex-PCR (Filmarray®), viral loads by PCR and cytokine panel (Luminex®, 38 cytokines) were performed. The following outcomes were evaluated: upper/lower respiratory tract disease (RTD), admission to ICU, mechanical ventilation, mortality and antimicrobial withdrawal. Results: Of 56 febrile episodes, 35 (63%) were RVI, 12 (21%) BI and 9 (16%) with unknown etiology (UE). Median of age was 8.5 years, 62% male gender. Rhinovirus (54%) and coronavirus (15%) were the more frequent detected viruses. No significant differences in cytokine levels were observed between RVI and BI. 94% of RVI patients had symptomatic RTD, versus 33% in BI and 33% in UE group (p < 0.001), with lower-RTD in 69% of RVI group (p < 0,001). Admission to ICU was 11% in RVI, 17% in BI and 11% in UE group (p = 0.88); only 2 patients required mechanical ventilation (p = 0.37) and no mortality was reported. After an RVI was detected by PCR, antimicrobials were withdrawal in 26% of patients with RVI (p: 0.04). Conclusion: RVI are frequent etiologic agents in febrile episodes of patients with HSCT. Viral detection might help to rationalize the use of antimicrobials in this population.

Resumen: Introducción: La sangre de cordón umbilical (SCU) como fuente para trasplante de células proge- nitoras hematopoyéticas (TPH) está bien establecida. Internacionalmente, menos del 10% de los TPH de SCU corresponde a donantes hermanos compatibles. Dentro de la red del Programa Infantil Nacional de Drogas Antineoplásicas (PINDA), existe desde enero 2004 un programa de donación dirigida de SCU para TPH. Pacientes y Método: Se diseñó un estudio observacional, retrospectivo, descriptivo, se revisaron el número y características de las unidades de SCU recolectadas en el PINDA y el número, características y evolución de los pacientes trasplantados con esas unidades entre enero de 2004 y octubre de 2018. Resultados: Sesenta unidades de SCU han sido recolectadas, de ellas 55 con registro completo. La mediana de volumen de las unidades almacenadas fue 74,8 ml (30,0-170,8), la mediana de células nucleadas totales 7,6 x 10e8 (2,0-21,1), mediana de células CD34+ 1,6 x 10e6 (0,2-11,6). Cuatro pacientes con leucemias de alto riesgo fueron trasplantados; mediana de segui miento es de 8 años. Todos desarrollaron complicaciones severas post TPH, uno de ellos falleció de recaída y los tres actualmente vivos presentan un Karnofsky/Lansky 100%. Conclusión: El programa ha permitido el trasplante de 4 pacientes que de otro modo no habrían tenido acceso a un donante. Este programa de donación dirigida puede ser considerado una primera etapa para el desarrollo de un banco público de sangre de cordón umbilical en Chile.
Abstract: Introduction: Cord blood (CB) as a source of Hematopoietic Stem Cells for Transplantation (HSCT) is well established. Worldwide, nonetheless, less than 10% of the CB HSCTs are performed with a match sibling donor. Since 2004, the Chilean National Childhood Cancer Program (PINDA) net work, has established a CB directed donation program for HSCT. Patients and Method: An obser vational, descriptive and retrospective study was designed to assess the number and characteristics of the CB units collected in the program as well as the number, clinical characteristics and follow-up of the patients who received an HSCT from those CB units between January 2004 and October 2018. Results: Sixty CB units have been collected; 55 of them with full records and stored. The median volume collected was 74.8 ml (30.0-170.8), the median number of total nucleated cells was 7.6 x 10e8 (2.0-21.1), and the median of CD34+ cells was 1.6 x 10e6 (0.2-11.6). Four high-risk leukemia patients received HSCT, all of them developed severe complications after transplantation and one patient died due to relapse. Those patients currently alive have a 100% Karnofsky/Lansky score. The median follow-up time was 8 years. Conclusion: The PINDA program has allowed 4 patients to be transplan ted who otherwise would not have had access to a donor. This directed donation program could be seen as a model for the development of a public cord blood bank in Chile.

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)

Introducción: La Enfermedad del Injerto Contra el Hospedador es la complicación más frecuente de los Trasplantes de Células Madre Hematopoyéticas y de todos los trasplantes que contengan células inmunocompetentes alogénicas, el 100 por ciento la padecen y cerca del 30 por ciento mueren por su causa; una proporción alta de casos son esteroide-refractarios, asimismo otras medidas inmunosupresoras modernas fracasan. En los campos de la Inmunoterapia y la Vaccinología también existe una escasez preocupante de inmunomoduladores de origen biológico potentes, efectivos, seguros y de amplio espectro. Existe un modelo híbrido murino de gran utilidad metodológica para estudios experimentales. Objetivo: Evaluar dos formulaciones novedosas de origen biotecnológico, una de ellas inmunopotenciadora y otra inmunosupresora, desarrolladas como cocleatos. Material y Métodos: Mediante Microscopia Electrónica y RT-PCR se caracterizaron las formulaciones como nanopartículas y su capacidad de regular la expresión del ARNm de linfoquinas definitorias de sus perfiles, respectivamente. Empleando el modelo de Enfermedad del Injerto Contra el Hospedador en ratón híbrido F1 (CBAxC57BL), se evaluó su carácter inmunomodulador in vivo . Resultados: Partiendo de los proteoliposomas de Neisseria meningitidis, se obtuvieron dos formulaciones en forma de cocleatos, ambas con diámetros de partícula inferior a 100nm. La Formulación 1mostró un perfil proinflamatorio con potente capacidad de aumentar el IFNγ y el TNFα y potenció el Índice de Bazo hasta 2,05 en el modelo EICH con p=0,0002. La Formulación 2 mostró un perfil supresor-regulatorio con potente capacidad de aumentar la IL-10 y el TGFβ y además de suprimir la producción de TNFα. En el modelo usado, esta formulación, suprimió el Índice de Bazo de manera dosis dependiente y con alta significación estadística. Se corroboró el conocido perfil de seguridad y ausencia de reactogenicidad de ambas formulaciones. Conclusiones: Ambas formulaciones tienen potencial aplicación en los campos de la terapia de Enfermedad del Injerto Contra el Hospedador en otras patologías y en Vaccinología. Los resultados obtenidos en el presente trabajo fundamentan la conveniencia de continuar el desarrollo farmacéutico y completar la preclínica de ambas formulaciones(AU)
Introduction: Graft-versus-host disease is the most frequent complication of Hematopoietic Stem Cell Transplants and all transplants containing allogeneic immunocompetent cells; 100 percent of patients suffer from this complication and about 30 percent die for this particular cause. A high proportion of cases are steroid-refractory; likewise, other modern immunosuppressive measures fail. In the fields of Immunotherapy and Vaccinology, there is also a worrying shortage of powerful, effective, safe and broad spectrum immunomodulators of biological origin. There is a hybrid murine model of great methodological utility for experimental studies. Objective: To evaluate two novel formulations of biotechnological origin: an immunopotentiator formulation and an immunosuppressive one, which were developed as cochleates. Material and Methods: The formulations assayed by Electron Microscopy and RT-PCR were characterized as nanoparticles and for their capacity to regulate lymphokine mRNA expression profile, respectively. The immunomodulatory character was evaluated in vivo using Graft-versus-host disease in (CBAxC57BL) F1 hybrid mice. Results: Starting from the proteoliposomes derived from Neisseria meningitides, two cochleate formulations were obtained, both with particle diameters below 100 nm. Formulation 1 showed a proinflammatory profile with potent capacity to increase IFNγ and TNFα, and potentiated the Spleen Index up to 2.05 in the GVDH model with p = 0.0002. Formulation 2 showed a suppressor/regulatory profile with potent capacity to increase IL-10 and TGFβ and suppress the production of TNFα. In the model used, this formulation suppressed the Spleen Index in a dose-dependent manner with high statistical significance. The known safety profile and absence of reactogenicity of both formulations was corroborated. Conclusions: Both formulations have potential application in the fields of GVHD therapy and other pathologies as well as in Vaccinology. The results obtained in the present work suggest the usefulness to continue with the pharmaceutical development and complete the preclinical studies of both formulations(AU)

ABSTRACT Objective To evaluate the nutritional risk factors in patients eligible for hematopoietic stem cell transplantation. Methods A cross-sectional, descriptive study conducted with patients recruited from an hematology outpatient clinic. Study variables included demographic and clinical data, patient-generated global subjective assessment findings, anthropometric indicators, food intake and oxidative stress levels. The level of significance was set at 5% (p<0.05). Results The sample comprised 72 patients, mean age of 48.93 years (14.5%). Multiple myeloma was the most prevalent condition (51.4%) in this sample. Most patients (55.6%) were overweight according to body mass index and at risk of cardiovascular disease according to waist circumference, conicity index and percentage of body fat. Sarcopenia was associated with risk of cardiovascular disease, hip-to-waist ratio (p=0.021), muscle strength depletion (p<0.001), food intake (p=0.023), reduced functional capacity (p=0.048), self-reported well-nourished status; p=0.044) and inadequate vitamin B6 (p=0.022) and manganese (p=0.026) intake. Elevated oxidative stress, detected in 33.3% of patients in this sample, was not associated with sarcopenia. Conclusion Most patients in this sample were overweight and sarcopenic. Lean mass depletion was associated with risk of cardiovascular disease, reduced muscle strength, food intake changes, reduced functional capacity, self-reported well-nourished status and inadequate intake of vitamin B6 and manganese, but not with oxidative stress.
RESUMO Objetivo Avaliar os fatores de riscos nutricionais em pacientes pré-transplante de célula-tronco hematopoiética. Métodos Estudo transversal, descritivo, realizado com pacientes de um ambulatório de hematologia. As variáveis estudadas foram demográficas, dados clínicos, avaliação subjetiva global produzida pelo próprio paciente, indicadores antropométricos, ingestão alimentar e estresse oxidativo. Os dados foram considerados estatisticamente significativos quando p<0,05. Resultados A amostra do estudo foi constituída por 72 pacientes, com média de idade de 48,93 (14,5%) anos e com mieloma múltiplo (51,4%) como a patologia mais prevalente. Conforme índice de massa corporal, 55,6% dos pacientes encontravam-se com excesso de peso. De acordo com a circunferência da cintura, índice de conicidade e percentual de gordura corporal, houve prevalência de risco para doença cardiovascular. A sarcopenia foi associada ao risco de doença cardiovascular pela relação cintura/quadril (p=0,021), depleção da força muscular (p<0,001), além da ingestão alimentar (p=0,023), da capacidade funcional reduzida (p=0,048) e do diagnóstico de "bem nutrido" (p=0,044), conforme a avaliação subjetiva global, e com consumo inadequado de vitamina B6 (p=0,022) e de manganês (p=0,026). Dentre os avaliados, 33,3% apresentaram estresse oxidativo elevado sem associação com sarcopenia. Conclusão Pacientes do pré-transplante se apresentam, em sua maioria, com excesso de peso, mas com sarcopenia, estando essa ausência de massa magra associada a risco de doença cardiovascular, depleção da força muscular, alteração da ingestão alimentar, redução da capacidade funcional, classificação de "bem nutrido", segundo a avaliação subjetiva global e consumo inadequado de vitamina B6 e manganês, não estando associada a estresse oxidativo.
