The aim of this study is to investigate the impact of pre-engraftment bloodstream infections (BSIs) on the outcomes in acute leukemia patients undergoing myeloablative cord blood transplantation (CBT). A total of 226 acute leukemia patients who received unrelated CBT were enrolled in this study, and all these patients received an intensified myeloablative conditioning without ATG. Pre-engraftment BSIs occurred in 72 patients (31.9 %), and the median time of onset was 4.5 days after cord blood infusion, BSIs of gram-negative bacilli, and gram-positive cocci comprised of 63...

Over the past decade, several targeted therapies (e.g. imatinib, dasatinib, nilotinib) have been developed to treat Chronic Myeloid Leukemia (CML). Despite an initial response to therapy, drug resistance remains a problem for some CML patients. Recent studies have shown that resistance mutations that preexist treatment can be detected in a substantial number of patients, and that this may be associated with eventual treatment failure. One proposed method to extend treatment efficacy is to use a combination of multiple targeted therapies...

INTRODUCTION: The use of αβ+ T-cell-depleted grafts is a novel approach to prevent graft failure, graft-versus-host disease (GVHD), and non-relapse mortality (NRM) in patients undergoing haploidentical hematopoietic stem cell transplantation. PATIENT AND METHOD: Thirty-four patients with acute leukemia and lacking a match donor were treated with αβ T-cell-depleted allografts from haploidentical family donors. A total of 24 patients had acute myeloid leukemia (AML) and 10 had acute lymphoblastic leukemia...

BACKGROUND: Allogeneic stem cell transplantation is the only curative option for patients with acute myeloid leukemia (AML) experiencing relapse. Either matched sibling donor (MSD) or unrelated donor (UD) is indicated. METHODS: We analyzed 1554 adults with AML transplanted from MSD (n = 961) or UD (n = 593, HLA-matched 10/10, n = 481; 9/10, n = 112). Compared to MSD, UD recipients were older (49 vs 52 years, p = 0.001), transplanted more recently (2009 vs 2006, p = 0...

No clinical studies have investigated the role of decitabine as a part of the myeloablative conditioning regimen prior to UCBT for refractory or relapsed childhood AL in patients in NR status. The aim of this study was to identify the potential benefits of decitabine as a prior therapy before salvaged unrelated UCBT for refractory or relapsed childhood AL. Eight consecutive patients with childhood refractory/relapsed AL were enrolled in our study between 2013 and 2014. All patients were in NR status before the time of transplant and had features associated with poor outcomes, such as CNSL, MDS-AML, high WBC count at diagnosis, and hypodiploid status (FLT3+/ITD+)...

Chronic myeloid leukemia (CML) is a myeloproliferative disorder with a high number of well-differentiated neutrophils in peripheral blood and myeloid cells in bone marrow (BM). CML is derived from the hematopoietic stem cells (HSCs) with the Philadelphia chromosome (Ph(+), t(9;22)-(q34;q11)), resulting in generating a fusion oncogene, BCR/ABL1. HSCs with Ph(+) are defined as leukemia stem cells (LSCs), a subpopulation cell at the apex of hierarchies in leukemia cells and responsible for the disease continuous propagation...

Philadelphia chromosome-positive (Ph+) acute lymphoblastic leukemia (ALL) may include the lymphoid blast crisis of chronic myeloid leukemia (CML-BC). We applied fluorescence in situ hybridization (FISH) of the BCR-ABL fusion gene to peripheral blood and/or bone marrow smears to determine whether the fusion was restricted to mononuclear cell nuclei or if segmented cell nuclei representing mature neutrophils also carried the fusion (Seg-FISH). Among 20 patients with Ph+ ALL without a prior diagnosis of CML, 9 were Seg-FISH+ and 11 were Seg-FISH-...

The optimum method of donor natural killer cell infusion (DNKI) after allogeneic hematopoietic cell transplantation (HCT) remains unclear. Fifty-one patients (age range, 19 years to 67 years) with refractory acute leukemia underwent HLA-haploidentical HCT and underwent DNKI on days 6, 9, 13, and 20 of HCT. Median DNKI doses were .5, .5, 1.0, and 2.0 × 10(8)/kg cells, respectively. During DNKI, 33 of the 45 evaluated patients (73%) developed fever (>38.3°C) along with weight gain (median, 13%; range, 2% to 31%) and/or hyperbilirubinemia (median, 6...

Recruitment of tumor-associated macrophages and neutrophils (TAM and TAN) to solid tumors contributes to immunosuppression in the tumor microenvironment; however, their contributions to lymphoid neoplasms are less clear. In human chronic lymphocytic leukemia (CLL), tumor B cells lodge in lymph nodes where interactions with the microenvironment occur. Tumor cell homing stimulates proliferation, such that engagement of the B-cell receptor is important for malignant progression. In the Eμ-Tcl1 murine model of CLL, we identified gene expression signatures indicative of a skewed polarization in the phenotype of monocytes and neutrophils...

We sought to compare two graft-versus-host disease (GVHD) prophylaxis regimen, cyclosporine and methotrexate (CsA+MTX) with CsA+mycophenolate mofetil (MMF) in 77 acute leukemia patients who underwent hematopoietic stem cell transplant (HSCT) between January 2008 and March 2013. Fifty-three patients received CsA+MTX while 24 received CsA+MMF. The incidence of grade 3-4 mucositis and grade 3-4 diarrhea was 74 and 6 % with CsA+MTX compared to 33 % and 21 % with CsA+MMF (P = 0.001 and 0.09 respectively). Forty-two (79 %) patients in CsA+MTX group required total parenteral nutrition compared to 14 (58 %) in CsA+MMF group (P = 0...

Chronic neutrophilic leukemia (CNL) is a rare entity amongst myeloproliferative neoplasms (MPNs). The classical presentation of CNL is with splenomegaly, mature neutrophilic leucocytosis and hyperuricemia. We herein report a case who presented with symptoms of acute gouty arthritis. Physical examination showed typical red, tender tophi in the right hand, right foot and both pinnae suggesting an acute episode of gout. During evaluation, moderate splenomegaly, mature neutrophilia, hyperuricemia and sub-nephrotic range range proteinuria were noted...

Few studies have presented a comparison of myeloablative cord blood transplantation (CBT) and HLA-identical sibling hematopoietic cell transplantation (HCT) for AML in a disease-specific analysis, and the evaluation of GvHD-free and relapse-free survival (GRFS) in AML patients after unrelated CBT has not been reported. A total of 162 consecutive AML patients receiving intensified myeloablative unrelated CBT (n=107) or allogeneic PBSC transplantation (allo-PBSCT) or bone marrow transplantation (BMT) from an HLA-identical sibling donor (n=55) were investigated...

The relationship between primary hematologic disease and rheumatologic manifestations is well known, especially acute lymphocytic leukemia, lymphomas, plasma cell dyscrasias and myelodysplastic syndrome (MDS). Currently, more has been described about autoimmune manifestations in chronic myelomonocytic leukemia (CMML). Many different clinical scenarios may lead a patient with MDS/CMML initially to seek a rheumatological unit. Autoimmune features such as polymyalgia rheumatic symptoms, myositis, neutrophilic dermatosis, cutaneous vasculitis and positive antinuclear antibodies (ANA) are some examples of clinical presentation of MDS/CMML...

In diffuse large B-cell lymphoma (DLBCL), the number of circulating monocytes and neutrophils represents an independent prognostic factor. These cell subsets include monocytic and granulocytic myeloid-derived suppressor cells (M- and G-MDSCs) defined by their ability to suppress T-cell responses. MDSCs are a heterogeneous population described in inflammatory and infectious diseases and in numerous tumors including multiple myeloma, chronic lymphocytic leukemia, and DLBCL. However, their mechanisms of action remain unclear...

Increasing evidence support bimodal action of nitric oxide (NO) both as a promoter and as an impeder of oxygen free radicals in neutrophils (PMNs), however impact of high oxidative stress on NO generation is less explored. In the present study, we comprehensively investigated the effect of high oxidative stress on inducible nitric oxide synthase (iNOS) expression and NO generation in human PMNs. Our findings suggest that PMA or diamide induced oxidative stress in PMNs from healthy volunteers, and high endogenous ROS in PMNs of chronic myeloid leukemia (CML) patients attenuate basal as well as LPS/cytokines induced NO generation and iNOS expression in human PMNs...

Nonrelapse mortality (NRM) is the first cause of treatment failure after unrelated cord blood transplantation (UCBT) following myeloablative conditioning (MAC). In the last decade, reduced-intensity conditioning (RIC) regimens have been developed with the aim of reducing NRM and allowing older patients and those with medical comorbidities to benefit from UCBT. The aim of the current retrospective study was to compare transplantation outcomes of acute myeloid leukemia (AML) patients given UCBT after either RIC or MAC...

BACKGROUND: Techniques for banking cord blood units (CBUs) as source for hematopoietic stem cell transplantation have been developed over the past 20 years, aimed to improve laboratory efficiency without altering the biologic properties of the graft. A large-scale, registry-based assessment of the impact of the banking variables on the clinical outcome is currently missing. STUDY DESIGN AND METHODS: A total of 677 single cord blood transplants (CBTs) carried out for acute leukemia in complete remission in centers affiliated with the European Society for Blood and Marrow Transplantation were selected...
