Abstract
At our center, we observed a series of patients who developed transudative refractory ascites secondary to noncirrhotic, non-veno-occlusive disease (VOD)-related portal hypertension after allogeneic hematopoietic stem cell transplantation (allo-HSCT). Patients were considered to have idiopathic portal hypertension-related refractory ascites (IRA) if they developed ascites secondary to intrahepatic portal hypertension (serum ascites albumin gradient ≥1.1 g/dL or hepatic venous pressure gradient [HVPG] >5 mm Hg), but did not meet the clinical criteria for classical VOD/sinusoidal obstructive syndrome (SOS) and did not have any alternate etiology of portal hypertension. From our institutional database, we identified 40 patients who developed IRA after allo-HSCT between 2004 and 2018. The patients' median age at the time of allo-HSCT was 54 years (range, 21-73 years). The median time to development of IRA after allo-HSCT was 80 days (range, 16-576 days). The median number of paracentesis was 3 (range, 1-11), and 15 (38%) patients had an intraperitoneal catheter placed for continued drainage of the rapidly accumulating ascites. Portal pressures were measured in 19 patients; 6 (15%) had moderate portal hypertension (HVPG 6-9 mm Hg), and 13 (33%) had severe portal hypertension (HVPG ≥ 10 mm Hg). Liver biopsy was performed in 24 patients. None of the patients met the criteria for classical VOD/SOS (clinical/histological) or cirrhosis (histological). The cumulative incidence of nonrelapse mortality was 63%, and the median survival duration after the development of the IRA was 7 months (range, 0.8-125.6 months). IRA is a poorly understood and often fatal complication of allo-HSCT.

Abstract
Mesenchymal stromal cells (MSCs) are multipotent progenitors supporting bone marrow hematopoiesis. MSCs have an efficient DNA damage response (DDR) and are consequently relatively radio-resistant cells. Therefore, MSCs are key to hematopoietic reconstitution following total body irradiation (TBI) and bone marrow transplantation (BMT). The bone marrow niche is hypoxic and via the heterodimeric transcription factor Hypoxia-inducible factor-1 (Hif-1), hypoxia enhances the DDR. Using gene knock-down, we have previously shown that the Hif-1α subunit of Hif-1 is involved in mouse MSC radio-resistance, however its exact mechanism of action remains unknown. In order to dissect the involvement of Hif-1α in the DDR, we used CRISPR/Cas9 technology to generate a stable mutant of the mouse MSC cell line MS5 lacking Hif-1α expression. Herein, we show that it is the whole Hif-1 transcription factor, and not only the Hif-1α subunit, that modulates the DDR of mouse MSCs. This effect is dependent upon the presence of a Hif-1α protein capable of binding to both DNA and its heterodimeric partner Arnt (Hif-1β). Detailed transcriptomic and proteomic analysis of Hif1a KO MS5 cells leads us to conclude that Hif-1α may be acting indirectly on the DNA repair process. These findings have important implications for the modulation of MSC radio-resistance in the context of BMT and cancer.

Abstract
Objetivo Estimar la razón de costo-efectividad de las pruebas para estratificación del riesgo en pacientes pediátricos con Leucemia Mieloide Aguda (LMA).Métodos Se construyó un árbol de decisión con años de vida ganados como medida de efectividad. Los costos fueron estimados desde la perspectiva del sistema de salud colombiano. En los costos de la estratificación se incluyeron los costos del tratamiento consecuente con ella. Los precios de medicamentos fueron tomados del SISMED 2008 y el valor monetario de los procedimientos se extrajo del manual tarifario del ISS 2001 adicionando el 30 %. Todos los costos se expresaron en pesos colombianos del 2010 y el producto interno per-cápita de ese año fue empleado como umbral de costo efectividad. Se condujeron análisis de sensibilidad univariados y probabilísticos.Resultados La razón de costo-efectividad incremental de las pruebas de estratificación a todos los pacientes, fue de $8 559 944. Los resultados son sensibles a las probabilidades de recaída, supervivencia al trasplante y efectos secundarios.Conclusión Las pruebas para estratificación del riesgo en LMA son costo-efectivas dentro del sistema de salud colombiano.

Abstract
BACKGROUND The prevalence and features of graft-versus-host disease (GVHD) in patients receiving allografts using peripheral blood stem cells (PBSCs) after a reduced-intensity conditioning (RIC) regimen are not well known. Several features of GVHD in patients at two institutions using RIC were assessed. METHODS We analysed the overall survival (OS) and prevalence of GVHD in patients who underwent outpatient allogeneic PBSC transplantation after RIC between October 1998 and July 2008. RESULTS We included 301 patients with a median age of 30 yrs (range, 1-71 yrs). In 37 cases, allogeneic peripheral blood stem cell transplantation was indicated for non-malignant disease, and in 264 for malignant disease. The median OS was 35 months. The estimated 3-yr OS was 48%. A total of 154 patients developed GVHD: there were 64 acute, 50 chronic and 40 cases that progressed from acute to chronic. Of the 104 patients with acute GVHD (aGVHD), 40% had grade I and 60% had grades II-IV. Of the 90 patients with chronic GVHD (cGVHD), 67% had limited and 33% had extensive forms. A total of 160 patients died, 40 as a result of GVHD (24 from aGVHD and 16 from cGVHD), 50 as a result of progressive disease and 70 from diverse causes. CONCLUSIONS The incidence of GVHD was lower than in other series using conventional myeloablative preparative regimens. Most importantly, the severity of GVHD did not significantly affect the long-term survival.

Abstract
BACKGROUND We previously showed that antithymocyte globulin (ATG) given with total body irradiation (TBI) 200 cGy and fludarabine results in high rate of donor engraftment. Its influence on acute and chronic graft versus host disease (GVHD) and on graft versus tumor effect is less known. METHODS Sixty-five patients underwent nonmyeloablative stem cell transplant with ATG, TBI 200 cGy, and fludarabine. GVHD prophylaxis was mycophenolate mofetil and cyclosporine. Forty-two patients (pts) (65%) had match related donors, 18 (27%) match unrelated, 1 (1.5%) mismatch related, and 4 (6%) mismatch unrelated donors. RESULTS At a median follow-up of 862 days, 24 patients (37%) developed GVHD. The median age of the patients with and without GVHD was 56 years respectively. Acute GVHD grade II-IV developed in 19 pts (29%). Fatal GVHD of liver and/or gut occurred in nine pts (14%). Forty-one pts survived more than 100 days. Five pts (12%) had chronic GVHD, two had extensive, and three had limited involvement. Relapsed disease was observed in 22 pts (34%). Infections occurred in 15 pts (23%) and were fatal in 13 (20%). CONCLUSIONS The addition of ATG to TBI 200cGy and fludarabine resulted in a modest incidence of GVHD. The best transplant outcomes were observed in pts with lymphoid malignancies.

Abstract
PURPOSE The high rate of toxicity is the limitation of myeloblastive regimens before allogeneic transplantation. A reduced intensity regimen can allow engraftment of stem cells and subsequent transfer of immune cells for the induction of a graft-vs.-tumor reaction. METHODS AND MATERIALS The data from 130 patients (80 males and 50 females) treated between 1998 and 2003 for various hematologic malignancies were analyzed. The median patient age was 50 years (range, 3-72 years). Allogeneic transplantation using peripheral blood or bone marrow, or both, was performed in 104 (82%), 22 (17%), and 4 (3%) patients, respectively, from HLA identical sibling donors (n = 93, 72%), matched unrelated donors (n = 23, 18%), mismatched related donors (4%), or mismatched unrelated donors (6%). Total body irradiation (TBI) at a dose of 2 Gy delivered in one fraction was given to 101 patients (78%), and a total dose of 4-6 Gy was given in 29 (22%) patients. The median dose rate was 14.3 cGy/min (range, 6-16.4). RESULTS After a median follow-up period of 20 months (range, 1-62 months), engraftment was obtained in 122 patients (94%). Acute graft-vs.-host disease of Grade 2 or worse was observed in 37% of patients. Multivariate analysis showed three favorable independent factors for event-free survival: HLA identical sibling donor (p < 0.0001; relative risk [RR], 0.15), complete remission (p < 0.0001; RR, 3.08), and female donor to male patient (p = 0.006; RR 2.43). For relapse, the two favorable prognostic factors were complete remission (p < 0.0001, RR 0.11) and HLA identical sibling donor (p = 0.0007; RR 3.59). CONCLUSIONS In this multicenter study, we confirmed high rates of engraftment and chimerism after the reduced intensity regimen. Our results are comparable to those previously reported. Radiation parameters seem to have no impact on outcome. However, the lack of a statistically significant difference in terms of dose rate may have been due, in part, to the small population size in the subgroup analysis.

Abstract
A reduced-intensity conditioning allogeneic stem cell transplantation was given to 19 patients (aged 15-59 years) in the first chronic phase and one patient in the accelerated phase with chronic myeloid leukemia (CML) after a regimen consisting of fludarabine (Flu), busulfan (Bu) and ATG Fresenius. The median follow-up was 27 months. Until day +100, no transplant-related mortality was recorded. The incidence of acute and chronic graft-versus-host disease (GvHD) was 55 and 75%, respectively. Two patients (10%) died from GvHD. Fourteen (70%) patients achieved molecular remission. Additional post-transplant intervention (donor lymphocyte infusion, imatinib) was necessary, however, in 10 patients (50% of the patients; non-achievement of stable molecular remission or later relapses). The total direct cost of the transplantation treatment for all of the patients came to 1,572,880 euro. If the patients had been treated with imatinib and followed-up with the same time period as they were following a transplantation, the direct cost of the imatinib treatment would have been 2,005,117 euro. The transplantation treatment appears to be less expensive after approximately 2 years of follow-up. Flu+Bu+ATG is a low-toxicity regimen for patients with CML. However, a close follow-up is necessary and about 50% of the patients require further therapeutic intervention.

Abstract
Using a reduced-intensity stem cell transplantation (RIST) schedule, 24 patients with Philadelphia (Ph1) (+) chronic myelogenous leukemia (CML) in first chronic phase (CP) were prospectively allografted in four Latin American countries: México, Brazil, Colombia and Venezuela, using HLA-identical siblings as donors. The median age of the patients was 41 years (range 10-71 years); there were eight females. Patients received a median of 4.4 x 10(6)/kg CD34 cells. The median time to achieve above 0.5 x 10(9)/l granulocytes was 12 days, range 0-41 days, and the median time to achieve above 20 x 10(9)/l platelets was also 12 days, range 0-45 days. In all, 22 patients are alive 81-830 (median 497) days after RIST. The 830-day probability of survival is 92%, and the median survival has not been reached, being beyond 830 days. A total of 11 patients (46%) developed acute graft-versus-host disease (GVHD), and seven of 23 (30%) developed chronic GVHD. Two patients died 43 and 210 days after RIST, one as a result of sepsis and the other of chronic GVHD. The 100-day mortality was 4.4%, and transplant-related mortality was 8%. RIST for patients with CML in CP appears to be an adequate therapeutic option.

Abstract
Nonmyeloablative allogeneic peripheral blood progenitor cell transplantation with low-dose total body irradiation (TBI; 200 cGy) plus fludarabine followed by cyclosporine and mycophenolate mofetil results in modest graft rejection rates. Acute and chronic graft-versus-host diseases (GVHD) are also seen and may not differ substantially from those that occur after fully ablative transplantation. Adding antithymocyte globulin (ATG) to pretransplant conditioning produces substantial immunosuppression. Because of its persistence in the circulation, ATG can achieve in vivo T-cell depletion. Twenty-five patients who were not eligible for conventional fully ablative allogeneic stem cell transplantation by virtue of age or comorbidities underwent nonmyeloablative allogeneic transplantation with ATG 15 mg/kg/d days -4 to -1, TBI 200 cGy on a single fraction on day -5, and fludarabine 30 mg/m(2)/d on days -4 to -2. Oral mycophenolate mofetil 15 mg/kg every 12 hours and cyclosporine 6 mg/kg every 12 hours were started on day -5. Grafts were unmanipulated peripheral blood progenitor cells mobilized with filgrastim 10 microg/kg/d and collected on day 5. The median age of the recipients was 57 years (range, 30-67 years); diagnoses were non-Hodgkin lymphoma (n = 11), acute myeloid leukemia (n = 6), multiple myeloma (n = 3), acute lymphoblastic leukemia (n = 2), severe aplastic anemia (n = 1), paroxysmal nocturnal hemoglobinuria (n = 1), and myelodysplastic syndrome (n = 1). The median CD34(+) and CD3(+) contents of the grafts were 7.6 x 10(6)/kg and 1.6 x 10(8)/kg, respectively. Five patients received voluntary unrelated donor grafts. Three patients, 2 with voluntary unrelated donor grafts and 1 with a sib donor, received a 1 antigen-mismatched graft. The rest were fully matched. Twenty-two of 25 patients were evaluable for chimerism. Sixteen had >/=95% donor chimerism. Four patients displayed 80% to 90% donor chimerism, 1 displayed 78%, and 1 displayed 64%. Eleven patients relapsed with their original disease. One patient rejected the graft at 180 days. The median hospital stay was 27 days. Complications included GVHD in 6 patients (3 patients had grade I or II GVHD of skin and liver, and 3 patients had grade III or IV GVHD of liver and gut). Two of the patients with GVHD had mismatched grafts. Transplant-related toxicity was seen in 4 patients and infection in 5 patients. The median length of follow-up was 162 days (range, 17-854 days). Complete remissions were seen in 10 patients. Four patients remained in complete response (CR) at 280 to 595 days. One patient relapsed with non-Hodgkin lymphoma after a CR of 728 days. Of the 25 patients, 16 died (6 of relapsed disease, 4 of GVHD, 3 of infection, and 3 of transplant-related toxicity) and 9 are alive (6 with CR-2 of them after donor leukocyte infusion-and 3 with relapsed disease). The addition of ATG to low-dose TBI and fludarabine nonmyeloablative conditioning was well tolerated and resulted in >80% donor engraftment in this small cohort. As in other series of truly nonmyeloablative transplantation, a high rate of relapse was observed. Donor engraftment may be facilitated by the addition of ATG to low-dose TBI and fludarabine conditioning.
