Abstract
BACKGROUND Transfusion-related iron overload (TRIO) is a widely acknowledged late effect of antineoplastic therapy in pediatric cancer survivors, but firm guidelines as to screening protocols or at-risk populations are lacking in the literature. PROCEDURE We performed retrospective analysis of all oncology patients diagnosed at our center from 2014 to 2019, who underwent TRIO screening as part of an internal quality improvement project. Correlations of MRI-confirmed TRIO with patient-, disease-, and treatment-specific features were evaluated. RESULTS We show that a tiered screening algorithm for TRIO, when followed as intended, led to the identification of the highest proportion of patients with TRIO. We confirm that cardiac TRIO is quite rare in the oncology patient population. However, accepted surrogate markers including red blood cell transfused volume and ferritin only modestly correlated with TRIO in our patient cohort. Instead, we found that older age, leukemia diagnosis, anthracycline exposure, and receipt of stem cell transplant were most strongly associated with risk for TRIO. CONCLUSIONS We describe associations between TRIO and patient, disease, and treatment characteristics in a multivariate risk model that could lead to an improved risk stratification of off-therapy patients, and which should be validated in a prospective manner.

Management of adult patients with CMML undergoing allo-HCT: recommendations from the EBMT PH&G Committee. Blood 2024; 143:2227-2244. [PMID: 38493484 DOI: 10.1182/blood.2023023476] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/06/2023] [Revised: 02/07/2024] [Accepted: 02/23/2024] [Indexed: 03/19/2024] Open
Abstract
ABSTRACT Chronic myelomonocytic leukemia (CMML) is a heterogeneous disease presenting with either myeloproliferative or myelodysplastic features. Allogeneic hematopoietic cell transplantation (allo-HCT) remains the only potentially curative option, but the inherent toxicity of this procedure makes the decision to proceed to allo-HCT challenging, particularly because patients with CMML are mostly older and comorbid. Therefore, the decision between a nonintensive treatment approach and allo-HCT represents a delicate balance, especially because prospective randomized studies are lacking and retrospective data in the literature are conflicting. International consensus on the selection of patients and the ideal timing of allo-HCT, specifically in CMML, could not be reached in international recommendations published 6 years ago. Since then, new, CMML-specific data have been published. The European Society for Blood and Marrow Transplantation (EBMT) Practice Harmonization and Guidelines (PH&G) Committee assembled a panel of experts in the field to provide the first best practice recommendations on the role of allo-HCT specifically in CMML. Recommendations were based on the results of an international survey, a comprehensive review of the literature, and expert opinions on the subject, after structured discussion and circulation of recommendations. Algorithms for patient selection, timing of allo-HCT during the course of the disease, pretransplant strategies, allo-HCT modality, as well as posttransplant management for patients with CMML were outlined. The keynote message is, that once a patient has been identified as a transplant candidate, upfront transplantation without prior disease-modifying treatment is preferred to maximize chances of reaching allo-HCT whenever possible, irrespective of bone marrow blast counts.

Plasma from patients undergoing allogeneic hematopoietic stem cell transplantation promotes NETOSIS in vitro and correlates with inflammatory parameters and clinical severity. Front Immunol 2024; 15:1353106. [PMID: 38550584 PMCID: PMC10972998 DOI: 10.3389/fimmu.2024.1353106] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/09/2023] [Accepted: 02/28/2024] [Indexed: 04/02/2024] Open
Abstract
Introduction NETosis, the mechanism by which neutrophils release extracellular traps (NETs), is closely related to inflammation. During the allogeneic hematopoietic stem cell transplantation (allo-HSCT), different stimuli can induce NETs formation. Inflammation and endothelial injury have been associated with acute graft-versus-host disease (aGVHD) and complications after allo-HSCT. We focus on the study of NETosis and its relation with cytokines, hematological and biochemical parameters and clinical outcomes before, during and after allo-HSCT. Methods We evaluate the capacity of plasma samples from allo-HSCT patients to induce NETosis, in a cell culture model. Plasma samples from patients undergoing allo-HSCT had a stronger higher NETs induction capacity (NETsIC) than plasma from healthy donors throughout the transplantation process. An optimal cut-off value by ROC analysis was established to discriminate between patients whose plasma triggered NETosis (NETs+IC group) and those who did not (NETs-IC group). Results Prior to conditioning treatment, the capacity of plasma samples to trigger NETosis was significantly correlated with the Endothelial Activation and Stress Index (EASIX) score. At day 5 after transplant, patients with a positive NETsIC had higher interleukin (IL)-6 and C-reactive protein (CRP) levels and also a higher Modified EASIX score (M-EASIX) than patients with a negative NETsIC. EASIX and M-EASIX scores seek to determine inflammation and endothelium damage, therefore it could indicate a heightened immune response and inflammation in the group of patients with a positive NETsIC. Cytokine levels, specifically IL-8 and IL-6, significantly increased after allo-HSCT with peak levels reached on day 10 after graft infusion. Only, IL-10 and IL-6 levels were significantly higher in patients with a positive NETsIC. In our small cohort, higher IL-6 and IL-8 levels were related to early severe complications (before day 15 after transplant). Discussion Although early complications were not related to NETosis by itself, NETosis could predict overall non-specific but clinically significant complications during the full patient admission. In summary, NETosis can be directly induced by plasma from allo-HSCT patients and NETsIC was associated with clinical indicators of disease severity, cytokines levels and inflammatory markers.

Abstract
ABSTRACT The myelodysplastic syndromes (MDSs) constitute a profoundly heterogeneous myeloid malignancy with a common origin in the hemopoietic stem cell compartment. Consequently, patient management and treatment are as heterogeneous. Decision-making includes identifying risk, symptoms, and options for an individual and conducting a risk-benefit analysis. The only potential cure is allogeneic stem cell transplantation, and albeit the fraction of patients with MDS who undergo transplant increase over time because of better management and increased donor availability, a majority are not eligible for this intervention. Current challenges encompass to decrease the relapse risk, the main cause of hematopoietic stem cell transplantation failure. Hypomethylating agents (HMAs) constitute firstline treatment for higher-risk MDSs. Combinations with other drugs as firstline treatment has, to date, not proven more efficacious than monotherapy, although combinations approved for acute myeloid leukemia, including venetoclax, are under evaluation and often used as rescue treatment. The treatment goal for lower-risk MDS is to improve cytopenia, mainly anemia, quality of life, and, possibly, overall survival. Erythropoiesis-stimulating agents (ESAs) constitute firstline treatment for anemia and have better and more durable responses if initiated before the onset of a permanent transfusion need. Treatment in case of ESA failure or ineligibility should be tailored to the main disease mechanism: immunosuppression for hypoplastic MDS without high-risk genetics, lenalidomide for low-risk del(5q) MDS, and luspatercept for MDS with ring sideroblasts. Approved therapeutic options are still scarcer for MDS than for most other hematologic malignancies. Better tools to match disease biology with treatment, that is, applied precision medicines are needed to improve patient outcome.

Abstract
OBJECTIVE Iron overload (IO) is a common and life-threatening complication resulting from the therapy of AL and HCT patients. This study aimed to evaluate the prognostic value of 12 serum biomarkers of iron metabolism in pediatric patients treated for AL or undergoing HCT. PATIENTS Overall, 50 patients with AL after intensive treatment and 32 patients after HCT were prospectively included in the study. AL patients at diagnosis and healthy controls served as reference groups. METHODS The impact of the following 12 serum iron metabolism parameters on the outcome of AL/HCT patients was analyzed: iron, transferrin (Tf), total iron-binding capacity (TIBC), ferritin, ferritin heavy chains (FTH1), ferritin light chains (FTL), hepcidin, soluble hemojuvelin (sHJV), soluble ferroportin-1 (sFPN1), erythroferrone (ERFE), erythropoietin (EPO), and soluble transferrin receptor (sTfR). RESULTS With a median follow-up of 2.2 years, high levels of ferritin and low levels of sHJV had an adverse prognostic impact on OS and EFS in children after HCT. If these patients were combined with those with AL after intensive chemotherapy, the results were confirmed for OS and EFS both for ferritin and sHJV. CONCLUSIONS Among the 12 analyzed serum parameters of iron metabolism, increased levels of ferritin and decreased levels of sHJV had an adverse prognostic impact on survival in children after HCT. More data are needed to clarify the relationship between ferritin, sHJV, and mortality of AL children after intensive chemotherapy, and more extensive prospective studies are required to prove sHJV predictivity.

Iron Chelation with Deferasirox Suppresses the Appearance of Labile Plasma Iron During Conditioning Chemotherapy Prior to Allogeneic Stem Cell Transplantation. Transplant Cell Ther 2023; 29:42.e1-42.e6. [PMID: 36241148 DOI: 10.1016/j.jtct.2022.10.002] [Citation(s) in RCA: 3] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/21/2022] [Revised: 09/12/2022] [Accepted: 10/06/2022] [Indexed: 11/06/2022]
Abstract
During conditioning chemotherapy prior to allogeneic haematopoietic stem cell transplantation (HSCT), non-transferrin-bound iron and its chelatable form, labile plasma iron (LPI), regularly appear in the blood of patients at high levels of transferrin saturation (TfS). As these free iron species potentially favor infection and mediate transplantation-associated toxicities, chelation therapy could be an approach to improve outcome after transplantation. However, data addressing iron chelation in the immediate peritransplantation period are sparse. In this study, we investigated the influence of iron chelation with deferasirox during conditioning chemotherapy on the appearance of LPI, the incidence of infection and toxicities, and the tolerability of this treatment in the peritransplantation period. We conducted this single-center prospective observational study in 25 adults with iron overload (serum ferritin >1000 µg/L) undergoing allogeneic HSCT after myeloablative busulfan-based conditioning chemotherapy. Patients received iron chelation with deferasirox (14 mg/kg) from the start of conditioning until day 3 post-transplantation. Iron parameters, including LPI, were obtained at the chelator's trough level daily until day 0 and then on days 4, 7, and 14. Data on infection (bacteremia or invasive fungal disease) and toxicity, as well as the tolerability of deferasirox, were collected until the end of the follow-up period on day 28. Data were analyzed descriptively. TfS levels exceeded 70% in median on 6 days (range, 4 to 10 days) and in 63.6% (range, 36.4% to 90.9%) of the samples per patient, although in 19 of 25 patients (76%), no elevated LPI values were detected during the intake of deferasirox despite high TfS levels. Only 6 patients (24%) showed mildly increased LPI values (≤0.5 units) during the intake of deferasirox, 3 of whom had presented with elevated LPI values before the start of conditioning. Deferasirox was well tolerated, and no aggravation of toxicities was observed. Infection occurred in 5 patients (20%), including 3 of the 6 patients with elevated LPI values despite chelation therapy. In the present study, we demonstrate that iron chelation with deferasirox safely suppresses the appearance of LPI and might decrease the incidence of infection, whereas the impact on transplantation-associated toxicities remains to be elucidated.

The impact of pretransplant serum ferritin on haploidentical hematopoietic stem cell transplant for acquired severe aplastic anemia in children and adolescents. Pediatr Blood Cancer 2022; 69:e29845. [PMID: 35731841 DOI: 10.1002/pbc.29845] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/19/2022] [Revised: 05/08/2022] [Accepted: 05/31/2022] [Indexed: 01/19/2023]
Abstract
Haploidentical hematopoietic stem cell transplant (haplo-HSCT) provides an important alternative for children and adolescents with acquired severe aplastic anemia (SAA) lacking matched donors. To test whether pretransplant serum ferritin (SF) represents a candidate predictor for survival and a potential biomarker for graft-versus-host disease (GvHD) in pediatric haplo-HSCT, we retrospectively evaluated 147 eligible patients with SAA who underwent haplo-HSCT. The patients were divided into the low-SF group (< 1000 ng/mL) and the high-SF group (≥ 1000 ng/mL). We found that SF ≥1000 ng/mL independently increased the risk of grade II-IV aGvHD (HR = 2.596; 95% CI, 1.304-5.167, P = 0.007) and grade III-IV aGvHD (HR = 3.350; 95% CI, 1.162-9.658, P = 0.025). Similar probabilities of transplant-related mortality at 100 days were observed in the two groups (6.19 ± 2.45% vs 8.00 ± 3.84%, P = 0.168). The two-year overall survival (85.29 ± 3.89% vs 92.00% ± 3.84%, P = 0.746) and failure-free survival (83.23% ± 4.08% vs 83.37% ± 6.27%, P = 0.915) were comparable. GvHD-/failure-free survival were 60.06 ± 5.10% and 75.56 ± 6.87%, respectively (P = 0.056). In conclusion, elevated pretransplant SF level is associated with higher incidences of grade II-IV aGvHD and grade III-IV aGvHD. However, it is not associated with worse survival after haplo-HSCT for children and adolescent patients with SAA.

Abstract
Poor graft function (PGF) is a life-threatening complication that occurs after transplantation and has a poor prognosis. With the rapid development of haploidentical hematopoietic stem cell transplantation, the pathogenesis of PGF has become an important issue. Studies of the pathogenesis of PGF have resulted in some success in CD34+-selected stem cell boosting. Mesenchymal stem cells, N-acetyl-l-cysteine, and eltrombopag have also been investigated as therapeutic strategies for PGF. However, predicting and preventing PGF remains challenging. Here, we propose that the seed, soil, and insect theories of aplastic anemia also apply to PGF; CD34+ cells are compared to seeds; the bone marrow microenvironment to soil; and virus infection, iron overload, and donor-specific anti-human leukocyte antigen antibodies to insects. From this perspective, we summarize the available information on the common risk factors of PGF, focusing on its potential mechanism. In addition, the safety and efficacy of new strategies for treating PGF are discussed to provide a foundation for preventing and treating this complex clinical problem.

Abstract
Since its introduction in clinical practice, eltrombopag (ELT) has demonstrated efficacy in heterogeneous clinical contexts, encompassing both benign and malignant diseases, thus leading researchers to make a more in-depth study of its mechanism of action. As a result, a growing body of evidence demonstrates that ELT displays many effects ranging from native thrombopoietin agonism to immunomodulation, anti-inflammatory, and metabolic properties. These features collectively explain ELT effectiveness in a broad spectrum of indications; moreover, they suggest that ELT could be effective in different, challenging clinical scenarios. We reviewed the extended ELT mechanism of action in various diseases, with the aim of further exploring its full potential and hypothesize new, fascinating indications.

Pretransplantation Red Blood Cell and Platelet Transfusion Burden in De Novo Myelodysplastic Syndrome Undergoing Allogeneic Transplantation. Transplant Cell Ther 2021; 27:671-678. [PMID: 33991723 DOI: 10.1016/j.jtct.2021.05.003] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/24/2021] [Revised: 04/30/2021] [Accepted: 05/02/2021] [Indexed: 12/28/2022]
Abstract
Most patients of myelodysplastic syndrome (MDS) require red blood cell (RBC) or platelet transfusion during their disease courses, which could cause an increased risk of iron overload and alloimmunization. However, it remains less clear whether pretransplantation RBC or platelet transfusion burden affects transplant outcomes in patients with MDS. The objective was to examine the significance of pretransplantation RBC and platelet transfusion burden on transplant outcomes after allogeneic HCT for adults with de novo MDS. We retrospectively evaluated the effect of pretransplantation RBC or platelet transfusion burden on transplant outcomes in a cohort of 1007 adult patients with de novo MDS treated by upfront allogeneic hematopoietic cell transplantation (HCT) between 2006 and 2018. Both higher pretransplantation RBC and platelet transfusion burdens were significantly associated with higher overall mortality and relapse-related mortality, but not non-relapse mortality in the multivariate analysis. Higher pretransplantation RBC transfusion burden was also significantly associated with lower neutrophil, platelet, and reticulocyte recovery in the multivariate analysis. In summary, our study clearly demonstrated that a higher pretransplantation RBC and platelet transfusion burden was independently associated with higher overall mortality, relapse-related mortality, and lower hematopoietic recovery after allogeneic HCT for de novo MDS. Early allogeneic HCT should be considered for patients with de novo MDS who require RBC and platelet transfusion repeatedly.
