BACKGROUND: Allogeneic hematopoietic cell transplantation (HCT) is a curative therapy for patients with acute myeloid leukemia (AML). However, post-HCT relapse and regimen-related toxicity remain significant barriers to long-term survival. In recent years, new conditioning regimens have been explored to improve transplantation outcomes in patients with AML. Treosulfan combines a potent immunosuppressive and antileukemic effect with a low toxicity profile. METHODS: To investigate the role of treosulfan-based conditioning, the European Society for Blood and Marrow Transplantation Acute Leukemia Working Party performed a registry analysis of 520 adult patients with AML who received treosulfan-based conditioning and underwent HCT between 2000 and 2012, including 225 patients in first complete remission, 107 in second or later complete remission, and 188 with active/advanced disease 188 (88 with primary refractory disease)...

Background.: Clostridium difficile infection (CDI) is a frequent complication in recipients of allogeneic hematopoietic stem cell transplantation (allo-HSCT), who receive intensive treatments that significantly disrupt the intestinal microbiota. In this study, we examined the microbiota composition of allo-HSCT recipients to identify bacterial colonizers that confer protection against CDI following engraftment. Methods.: Feces collected from adult recipients allo-HSCT at engraftment were analyzed; 16S rRNA genes were sequenced and analyzed from each sample...

BACKGROUND: Allogeneic hematopoietic stem cell transplantation (allo-HSCT) is the only treatment with a curative potential for myelodysplastic syndrome (MDS) patients. Allo-HSCT has substantial risks, particularly in the elderly, and its role for older MDS patients has yet to be defined. METHODS: We analyzed 88 MDS patients aged ≥ 60 years with allo-HSCT after reduced intensity conditioning regimens over the last decade. The study cohort had high risk features; 47 of 88 (53...

CD34(+)-selected stem cell boost (SCB) without conditioning have recently been utilized for poor graft function (PGF) after allogeneic hematopoietic stem cell transplantation (allo-HSCT) with promising results. Unfortunately, many patients have been unable to receive the boost infusion as their donors were unwilling or unable to undergo an additional stem cell collection. Therefore, we conducted this study utilizing either fresh or cryopreserved peripheral blood stem cell products to create CD34(+)-selected boost infusions for the treatment of PGF...

Allogeneic hematopoietic stem cell transplantation (allo-SCT) represents the only curative treatment for patients with myelodysplastic syndrome (MDS), but involves non-negligible morbidity and mortality. Crucial questions in clinical decision making include the definition of optimal timing of the procedure and the benefit of cytoreduction before transplant in high risk patients. We carried out a decision analysis on 1728 MDS who received supportive care, transplantation or hypomethylating agents (HMAs). Risk assessment was based on the revised International Prognostic Scoring System (IPSS-R)...

Epstein-Barr virus (EBV)-associated lymphoproliferative disorders (LPDs) sometimes occur following Anti-thymocyte globulin (ATG) administration for allogenic stem cell transplantation but are rare in aplastic anemia (AA) patients. A 55-year-old woman with AA following ATG developed refractory fever and was diagnosed with EBV-LPD. She was successfully treated with weekly rituximab monotherapy; however, she developed EBV encephalitis. She was admitted to the intensive care unit and finally recovered from unconsciousness...

High-risk (HR) multiple myeloma (MM) has poor outcomes with conventional therapy. Tandem autologous-non-myeloablative (NMA) allogeneic stem cell transplantation (autologous stem cell transplantation (ASCT)-NMA allogeneic SCT) is potentially curative secondary to graft-versus-myeloma effect. We retrospectively analysed ASCT-NMA allogeneic SCT outcomes of 59 HR and relapsed MM patients. At a median follow-up of 35.8 months, the outcomes for HR-MM upfront tandem ASCT-NMA allogeneic SCT and standard-risk (SR) MM upfront ASCT alone were comparable (median PFS 1166 days versus 1465 days, P=0...

Permanent alopecia after haematopoietic stem cell transplantation (HSCT) is distressing and few studies have investigated this late effect. The aim of the study was to assess the percentage of patients with alopecia and investigate risk factors for alopecia. Patients who underwent allogeneic HSCT before age 19 years, from January 1990 to January 2013, who were at least 2 years after transplant and in follow-up in our clinic were included. Alopecia was defined as clinically apparent decreased hair density. Possible risk factors considered for alopecia after HSCT included: gender, age, diagnosis, donor type, conditioning regimen: cranial irradiation (TBI/cranial radiotherapy) and/or chemotherapy, which chemotherapeutic agents were used and acute/chronic GvHD...

In order to clarify the association between hyperglycemia during the early period after allogeneic stem cell transplantation (allo-SCT) and adverse outcomes, we retrospectively analyzed 563 consecutive patients who underwent allo-SCT at our institute between 2008 and 2015. Patients were categorized into three groups according to mean fasting blood glucose levels on days 0-7 (normoglycemia group<110 mg/dL, n=347; mild hyperglycemia group 110-149 mg/dL, n=192 and moderate/severe hyperglycemia group≥150 mg/dL, n=24)...

The discovery of T regulatory cells has been one of the most important advances in basic immunology and has opened the door to the development of innovative therapeutic strategies for improving the outcome of solid organ and hematopoietic stem cell transplantation. Basic immunology is rapidly elucidating the complex biology of these cells even though the difficulties in purifying or even expanding them in vitro represent a major limitation to the development of clinical studies. The clinical benefit potentially associated with this therapeutic approach remains to be demonstrated...

The most common cause of post-transplant mortality in patients with hematological malignancy is relapse, followed by GvHD, infections, organ toxicity and second malignancy. Immune-mediated complications such as GvHD continue to be challenging, yet amenable to control through manipulation of the T-cell compartment of the donor graft with subsequent immunomodulation after transplant. However, risk of both relapse and infection increase concomitantly with T-cell depletion (TCD) strategies that impair immune recovery...

Allogeneic hematopoietic stem cell transplantation (HSCT) remains the only treatment option for several severe hematological malignancies. The development of graft-versus-host disease (GVHD) is a common complication of the procedure and results when donor T cells become activated against recipient-specific antigens. The factors that drive the alloreactive T cell response are not completely understood. In this issue of the JCI, Chung and colleagues present evidence that stromal cells within lymphoid tissue express the Notch ligands Delta-like 1/4 (DLL1 and DLL4), which in turn directly activate T cells...

INTRODUCTION: In the cytogenetically normal population of AML (CN-AML), FLT3-ITD-positive and wild-type NPM1 is correlated with a worse outcome, and FLT3-ITD-negative with NPM1-mut is correlated with a better outcome. This leaves a large subpopulation of CN-AML patients without NPM1 or FLT3-ITD mutations with heterogeneous outcomes with overall survivals (OS) ranging from several weeks to years. Therefore, new prognostic markers are needed to better risk stratify this subset of patients...

We present five cases of cytomegalovirus (CMV) pneumonitis occurring in patients after recent T cell deplete allogeneic stem cell transplantation (AlloHSCT). These cases were complicated by an organising pneumonia (during the recovery period) with a predominantly central peribronchial pattern. All patients presented with evidence of active CMV pneumonitis which was treated successfully with anti-viral therapy but was followed by persistent severe dyspnoea, cough and hypoxia. High resolution computed tomography (HRCT) imaging showed widespread central peribronchial consolidation with traction bronchiectasis...

Minimal Residual disease (MRD) in acute myeloid leukemia (AML) is typically measured using multi-parameter flow cytometry (MFC). Detection of leukemia mutations using multi-gene next generation sequencing (NGS) can potentially be used to measure residual disease. We used a targeted 28-gene NGS panel to detect mutations and different-from-normal 10-colour MFC to measure MRD in AML patients before allogeneic hematopoietic stem cell transplant (HCT). Residual disease was defined when any abnormal blast population was detected using MFC and when any leukemia allele was detected with a variant allele frequency (VAF) ≥5% using NGS...

Bone marrow (BM) niches, including the osteoblastic, vascular, and perivascular niches, are numerically impaired in patients with aplastic anemia (AA). It remains unclear whether these niches are numerically restored in AA patients after allogenic hematopoietic stem cell transplantation (allo-HSCT). To investigate changes in BM niches, we monitored 52 patients with AA who had undergone allo-HSCT and performed immunohistochemical studies of BM niches using antibodies against CD34, CD146, and osteopontin. After allo-HSCT, patients with AA exhibited a remarkable increase in the number of cellular elements in the BM niches, including the vascular and perivascular cells...

Multiple nonleukemic myeloid sarcoma (MS) is a rare form of MS that is developed in multiple anatomic sites other than bone marrow at diagnosis, without a preceding myeloid neoplasm. The prevalence, prognosis, and optimal management of multiple nonleukemic MS have not been addressed. The role of allogenic or autologous hematopoietic cell transplantation (HCT) for nonleukemic MS is also less well defined. We present a case of MS characterized by systemic lymphadenopathies and multiple effusions, which presumably had a very poor prognosis...
