RESUMEN
Veno-occlusive disease/sinusoidal obstruction syndrome (VOD/SOS) is a potentially life-threatening complication of haematopoietic cell transplantation (HCT) conditioning. The DEFIFrance post-marketing registry study evaluated effectiveness and safety in patients who received defibrotide. It collected retrospective/prospective patient data from 53 French HCT centres from July 2014 to March 2020. Primary endpoints were survival and complete response (CR; total serum bilirubin <2 mg/dL, multiorgan failure resolution) at Day 100 post-HCT among patients with severe/very severe VOD/SOS. A secondary endpoint was evaluation of treatment-emergent serious adverse events (TESAEs) of interest. Of 798 patients analysed, 251 and 81 received defibrotide treatment for severe/very severe VOD/SOS and mild/moderate VOD/SOS post-HCT, respectively; 381 received defibrotide for VOD/SOS prophylaxis. In patients with severe/very severe VOD/SOS post-HCT, Kaplan-Meier-estimated CR at Day 100 was 74% (95% confidence interval [CI]: 66%, 81%). At Day 100, 137/251 (55%) were alive and in CR. Kaplan-Meier-estimated Day 100 post-HCT survival was 61% (95% CI: 55%, 67%) in patients with severe/very severe VOD/SOS. TESAEs of interest occurred in 29% of these patients; VOD/SOS-related mortality at 12 months was 15%. DEFIFrance represents the largest collection of real-world data on post-registration defibrotide use, supporting the real-world utility of defibrotide for patients with severe/very severe VOD/SOS post-HCT.

BACKGROUND: There are currently few data on the outcome of acute myeloid leukemia (AML) in adolescents after allogeneic HSCT. The aim of this study is to describe the outcome and its specific risk factors for children, adolescents and young adults after a first allogeneic HSCT for AML. METHODS: In this retrospective study, we compared the outcome of AML patients receiving a first allogeneic HSCT between 2005 and 2017 according to their age at transplantation's time: children (< 15 years, n = 564), adolescent and post-adolescent (APA) patients (15-25 years, n = 647) and young adults (26-40 years; n = 1434). RESULTS: With a median follow-up of 4.37 years (min-max 0.18-14.73 years), the probability of 2-year overall survival (OS) was 71.4% in children, 61.1% in APA patients and 62.9% in young adults (p = 0.0009 for intergroup difference). Both relapse and non-relapse mortality (NRM) Cumulative Incidence (CI) estimated at 2 years were different between the age groups (30.8% for children, 35.2% for APA patients and 29.4% for young adults-p = 0.0254, and 7.0% for children, 10.6% for APA patients and 14.2% for young adults, p < 0.0001; respectively). Whilst there was no difference between the three groups for grade I to IV acute GVHD CI at 3 months, the chronic GVHD CI at 2 years was higher in APA patients and young adults (31.4% and 36.4%, respectively) in comparison to the children (17.5%) (p < 0.0001). In multivariable analysis, factors associated with death were AML cytogenetics (HR1.73 [1.29-2.32] for intermediate risk 1, HR 1.50 [1.13-2.01] for intermediate risk 2, HR 2.22 [1.70-2.89] for high cytogenetics risk compared to low risk), use of TBI ≥ 8 Grays (HR 1.33 [1.09-1.61]), disease status at transplant (HR 1.40 [1.10-1.78] for second Complete Remission (CR), HR 2.26 [1.02-4.98] for third CR and HR 3.07 [2.44-3.85] for active disease, compared to first CR), graft source (HR 1.26 [1.05-1.50] for Peripheral Blood Stem Cells compared to Bone Marrow) and donor age (HR 1.01 (1-1.02] by increase of 1 year). CONCLUSION: Age is an independent risk factor for NRM and extensive chronic GVHD. This study suggests that APA patients with AML could be beneficially treated with a chemotherapy-based MAC regimen and bone marrow as a stem cells source.

This multicenter prospective phase 2 trial analyzed disease-free survival (DFS) in myelofibrosis patients receiving ruxolitinib for 6 months before transplantation. Seventy-six patients were recruited. Age-adjusted dynamic international prognostic scoring system was intermediate-1, intermediate-2, and high in 27 (36%), 31 (41%), and 18 (24%) patients. All patients received ruxolitinib from inclusion to conditioning regimen (fludarabine-melphalan) or to progression. A donor was found in 64 patients: 18 HLA-matched sibling donor (MSD), 32 HLA-matched unrelated (UD10/10), and 14 HLA mismatched unrelated donor (UD9/10. Among 64 patients with a donor, 20 (31%) achieved a partial response before transplantation and 59 (92%) could be transplanted after ruxolitinib therapy (18/18 MSD, 30/21 UD10/10, 11/34 UD9/10), of whom 19 (32%) were splenectomized. Overall survival from inclusion was 68% at 12 months. One-year DFS after transplantation was 55%: 83%, 40%, and 34% after MSD, UD10/10 or UD9/10, respectively. Cumulative incidence of grade 2-4 acute graft-versus-host disease (GVHD) was 66% and non-relapse-mortality was 42% at 12 months. Short course of ruxolitinib before transplantation is followed by a high rate of transplantation. With the platform used in this protocol, outcome was much better in patients transplanted with HLA-matched sibling donor as compared to unrelated donor.

The presence of allo-antibodies in the serum of a recipient awaiting hematopoietic stem cell transplantation (HSCT) may have an impact on transfusion efficiency and/or donor choice, especially in the absence of an identical sibling donor. Prior to transplantation, donor specific anti-HLA (Human Leukocyte Antigen) antibodies (DSA) have a recognized effect on transplant outcome, correlated with the increasing MFI value and with the ability of such antibody to fix the complement fraction. Anti-platelet antibodies (anti-HLA class I and anti-HPA [Human Platelet Antigen]) are better involved in transfusion inefficiency and can be responsible for refractory status. ABO incompatibilities require a specific treatment of the graft in presence of high titer to avoid hemolytic adverse effects. Investigations of these antibodies should be carried out on a regular basis in order to establish appropriate transfusion recommendation, select an alternative donor when possible or adapt the source of cells. After transplantation, in case of delayed recovery or graft rejection, long term aplasia, persistent mixed chimerism or late release, and after elimination of the main clinical causes, a biological assessment targeted on the different type of antibodies will have to be performed in order to orient towards the cause or the appropriate therapy. Further studies should be carried out to determine the impact of anti-MICA antibodies and recipient specific anti-HLA antibodies, on the outcome of the transplantation.

Acute and chronic renal failures are very common after allogeneic HSCT. These complications have a real impact on mortality and morbidity of transplant recipients. Within the framework of the ninth workshops of practice harmonization of the Francophone Society of Bone Marrow Transplantation and Cellular Therapy (SFGM-TC) held in Lille in September 2018, various causes and mechanisms of renal failure, diagnostic work-up, treatment and recommendations to limit renal failure after transplantation are reviewed. Recommendations to adjust medications to avoid renal failure are also proposed in this article.

The quality of the information provided in post-transplant follow-up is necessary to obtain a coherent and exploitable database. Since the beginning of 2017, three forms (Med-B-allograft) have been available: the first month (Day 0), Day 100 (second report) and an annual follow-up report. Recommendations for follow-up were addressed in the 2014 harmonization workshop, "Harmonization of Data Coding ". However, it is sometimes difficult to determine which data to specify in ProMISe for post-transplantation. The objective of this workshop was to clarify certain situations and/or items.

The question of the best donor type between haploidentical (HAPLO) and matched-related donors (MRD) for patients with advanced HL receiving an allogeneic hematopoietic cell transplantation (allo-HCT) is still debated. Given the lack of data comparing these two types of donor in the setting of non-myeloablative (NMA) or reduced-intensity (RIC) allo-HCT, we performed a multicentre retrospective study using graft-vs.-host disease-free relapse-free survival (GRFS) as our primary endpoint. We analysed the data of 151 consecutive HL patients who underwent NMA or RIC allo-HCT from a HAPLO (N = 61) or MRD (N = 90) between January 2011 and January 2016. GRFS was defined as the probability of being alive without evidence of relapse, grade 3-4 acute GVHD or chronic GVHD. In multivariable analysis, MRD donors were independently associated with lower GRFS compared to HAPLO donors (HR = 2.95, P < 0.001). Disease status at transplant other than CR was also associated with lower GRFS in multivariable analysis (HR = 1.74, P = 0.01). In addition, the administration of ATG was independently linked to higher GRFS (HR = 0.52, P = 0.009). In summary, we observed significantly higher GRFS in HL patients receiving an allo-HCT using the HAPLO PT-Cy platform compared to MRD.

We performed a prospective multicenter phase 2 study to evaluate the safety and efficacy of prophylactic Extracorporeal Photopheresis (ECP) in adult patients with hematological malignancies early after RIC allo-HSCT on day 21 twice per week during the first two weeks and then once per week for the next four weeks for a total of eight ECP courses. A total of 20 patients were included; 10 were males, median age was 60 years. All patients engrafted, 17 (85%) received the total eight ECP courses. There were no adverse effects related to ECP. Seven patients developed acute graft-versus-host disease (GVHD), with 15% grade ≥ II cumulative incidence at day 100. The cumulative incidence of chronic GVHD at 2 years was 22%. The 2 years probability of overall survival (OS) and progression-free survival (PFS) were 84 and 74%, respectively. This study shows encouraging results with low acute and chronic GVHD incidence and no interference with graft-versus-leukemia (GVL) effect.

We have retrospectively compared survivals between acute myeloid leukemia (AML)/myelodysplastic syndrome (MDS) patients who received either a clofarabine/busulfan (CloB2A2) or a fludarabine/busulfan (FB2A2) RIC regimen for allogeneic stem cell transplantation. Between 2009 and 2014, 355 allotransplanted cases were identified from the SFGM-TC registry as having received either the FB2A2 (n = 316, 56% males, median age: 59.2 years, AML 78.5%, first complete remission [CR1] 72%, median follow-up: 20 months) or the CloB2A2 (n = 39, 62% males, median age: 60.8 years, AML 62%, CR1 69%, median follow-up: 22.4 months) RIC regimen. In multivariate analysis, FB2A2 was associated with significant lower overall survival (OS, HR: 2.14; 95%CI: 1.05-4.35, P = 0.04) and higher relapse incidence (RI, HR: 2.17; 95%CI: 1.02-4.61, P = 0.04) and a trend for lower leukemia-free survival (LFS, HR: 1.75; 95%CI: 0.94-3.26, P = 0.08). These results were confirmed using a propensity score-matching strategy. However, when considering AML and MDS patients separately, the benefit of the CLOB2A2 regimen was restricted to AML patients (2-year OS FB2A2: 38% [14.5-61.6] vs. CloB2A2: 79.2% [62.9-95.4], P = 0.01; 2-year LFS FB2A2: 38% [16-59.9] vs. CloB2A2: 70.8% [52.6-89], P = 0.03). The better survivals were due to the lower risk of relapse in this CloB2A2 AML subgroup (2-year RI FB2A2: 41.2% [19-62.4] vs. CloB2A2: 16.7% [5-34.2], P = 0.05). This retrospective comparison suggests that the CloB2A2 RIC regimen can likely provide longer survival than that awarded by a FB2A2 RIC regimen and may become a new standard of care RIC regimen for allotransplanted AML patients. A prospective phase 3 randomized study is warranted.

In the absence of an HLA matched familial donor, a search for an unrelated donor or cord blood unit is initiated through worldwide registries. Although a first look-up on available HLA information of donors in the "book" at BMDW (Bone Marrow Donor Worldwide) can provide a good estimation of the number of compatible donors, the variety of resolution typing levels requires confirmatory typing (CT) which are expensive and time consuming. In order to help recipient centers in their work. The French donor registry (France Greffe de Moelle/Agence de la Biomedecine) has recently developed a software program called "EasyMatch®" that uses haplotype frequencies to compute the likelihood of phenotypic match in donors according to various typing resolution levels. The goal of our study is to report a single monocentric user-experience with EasyMatch®, demonstrating that its routine use reduced the cost and the delay of the donor search in our center, allowing the definition of a new strategy to search compatible unrelated donors. The strategy was first established on a retrospective cohort of 217 recipients (185 adults and 32 children=before score) and then validated on a prospective cohort of 171 recipients (160 adults and 11 children=after score). For all patients, we calculated the delay between the registration day and the donor identification day, and the number of CT requested to the donor centre. Considering both groups, we could observe a significant decrease of the number of CT from 8 to 2 (p<0,001), and a significant decrease of the median delay to identify a suitable donor from 43 to 31days (p<0.0001). EasyMatch® estimates the number of potentially identical donors, but doesn't foresee availability of the donors. It provides us an easy tracking of mismatches, an estimation of the number of potential donors, the selection of population following ethnic origin of patients and a high prediction when probability is high or low. It affords a new approach of donor search in our daily work and improves the efficiency in the great challenge of the compatible donor identification.

The principal limitation of allogeneic hematopoietic stem cell transplantation except relapse remains the transplant-related mortality (TRM). In addition to graft-versus-host disease (GvHD), infections contribute to TRM in many patients. We describe herein a case of an adult patient presenting 5 months after haplo-identical transplantation an isolated fulminant hepatitis due to adenovirus.
RESUMEN
BACKGROUND: Despite frequent anemia and multiple transfusions in patients undergoing chemotherapy and allogeneic hematopoietic stem cell transplantation (allo-HSCT) for acute myeloid leukemia , recommendations for use of erythropoiesis-stimulating agents (ESAs) in these populations are still missing. The primary objective was the effect of ESA administration on patient's quality of life (QoL). Secondary objectives were hemoglobin (Hb) recovery, red blood cell (RBC) transfusions, overall survival, and event-free survival. METHODS: Adult patients with Hb ≤ 11 g/dL after consolidation chemotherapy for acute myeloid leukemia (group 1), or after allo-HSCT for any hematological diseases (group 2), were prospectively included. ESA was administered subcutaneously once per week during a maximum period of 6 months and was stopped when Hb level reached 12 g/dL. A paired-matched analysis using a historical control group was performed for secondary endpoints. Fifty-two patients were included in group 1, and 55 patients were in group 2. RESULTS: For the global population, a significant improvement of QoL was noticed with ESA use; 83% (group 1) and 71% (group 2) of patients achieved an Hb level ≥ 12 g/dL without transfusion requirement. The pair-matched analysis showed a reduction of 4 RBC units per patient in group 1 (P = .0002) and 3 RBC units per patient in group 2 (P = .04). No significant difference in terms of thromboembolic events, overall survival, and event-free survival was observed between ESA and control groups. A RBC transfusion median savings of 1712 per patient was estimated in each group. CONCLUSIONS: ESAs have a clinical and economic benefit on Hb recovery, could improve a patient's QoL, and lead to a significant reduction in number of RBC transfusions with no effect on survival.

Anti-human leukocyte antigen (HLA) antibodies are associated with several complications in solid organ transplantations, but their impact after allogeneic hematopoietic stem cell transplantation (allo-HSCT) is not yet well defined. To evaluate the relevance of anti-HLA antibodies, we have retrospectively analyzed 107 peripheral blood allo-HSCTs after reduced-intensity conditioning regimen between 2005 and 2010. Acute myeloid leukemia and multiple myeloma were the most frequent malignancies in the cohort. The detection of anti-HLA antibodies was systematically performed in all patients before transplantation. Anti-HLA antibodies were present in 24 patients (22%). There was no significant impact of anti-HLA antibodies on engraftment, incidence of relapse, and incidence of acute graft-vs-host disease. The presence of anti-HLA antibodies was associated with significantly worse overall survival (p = 0.006) and event-free survival (p = 0.024) after stratification on sex. The 3-year probability of overall survival was 34% without anti-HLA antibodies and 16% in their presence. Patients with anti-HLA antibodies had a higher transplant-related mortality associated with life-threatening vascular complications. Our study supports that anti-HLA antibodies should be tested and considered as an important impacting factor for transplantation outcomes after reduced-intensity conditioning allo-HSCT. We recommend its consideration before allo-HSCT in the donor-recipient selection parameters.
