Acute graft-versus-host disease (aGVHD) is a major complication of allogeneic haematopoietic stem cell transplantation (HSCT). With new promising therapies, survival may improve for severe aGVHD. We wanted to analyze the long-term outcome in patients who survive severe aGVHD. This study was a landmark analysis of 23,567 patients with acute Leukaemia who survived for more than 6 months after HSCT, 2002-2014. Patients alive after severe aGVHD (n = 1,738) were compared to controls. Patients with severe aGVHD had higher non-relapse mortality (NRM) and higher rate of extensive chronic GVHD (cGVHD) than the controls (p < 10(-5) )...

PC are a main cause of death following HSCT in children. We aimed to evaluate early predictors of mortality in paediatric recipients with PCs. A retrospective observational study of 35 patients with 49 episodes of PI on chest radiography (of 124 patients) who had undergone HSCT at a tertiary university hospital between January 2011 and December 2012 was performed. During follow-up (median 26.1 months), 15 episodes led to death (30.6%). An aetiologic diagnosis was made by non-invasive tests in 24 episodes (49...

Membrane-proximal and truncated mutations of colony-stimulating factor 3 receptor (CSF3R) are frequently found in chronic neutrophilic leukemia (CNL) and atypical chronic myeloid leukemia (aCML). However, rearrangement involving CSF3R in hematological neoplasms has not been reported. Here, we report a case of a 21-year-old female diagnosed as aCML with t(1;9)(p34;q34) who presented a CSF3R rearrangement. First, RNA sequencing identified a novel fusion transcript involving exon 17 of CSF3R and exon 50 of non-erythrocytic-1-spectrin-alpha (SPTAN1)...

Diarrhea after hematopoietic stem cell transplantation (HSCT) can be life-threatening, and its etiology includes conditioning regimens, graft-versus-host disease (GVHD), infections, and transplantation-associated microangiopathy (iTAM). Cord colitis syndrome (CCS) has been described as a syndrome of culture-negative and antibiotic-responsive persistent watery and non-bloody diarrhea of uncertain pathogenesis and occurs in umbilical cord blood transplantation (UCBT) recipients. We encountered a case similar to CCS that developed severe watery diarrhea after UCBT without any signs of GVHD or infection and responded well to metronidazole (MNZ) treatment...

The alloreactivity of natural killer (NK) cell after allogeneic hematopoietic stem cell transplantation (AHSCT) is regulated by the interaction between donor killer immunoglobulin-like receptors (KIRs) and recipient human leukocyte antigen (HLA)- class I molecules. The aim was to identify KIR genes, haplotypes and their HLA-class I ligands and to investigate their association with transplantion outcome. The study included 65 patient/donor pairs who received AHSCT from HLA-matched identical siblings. KIR genotyping was done for donors using reverse sequence specific oligonucleotide probes (rSSO) coupled with luminex technology, while HLA-C genotyping was performed in patients using rSSO strip assay...

Reconstitution of the adaptive immune system following allogeneic hematopoietic stem cell transplantation is crucial for beneficial outcome and is affected by several factors, such as GvHD and graft source. The impact of these factors on immune reconstitution has been thoroughly investigated during the early phase after transplantation. However, little is known about their long-term effect. Similarly, leukocyte telomere length (TL) shortening has been reported shortly after transplantation. Nevertheless, whether TL shortening continues in long-term aspect is still unsettled...

CD34+ cell selection significantly improves GvHD-free survival in allogeneic hematopoietic stem cell transplantation (allo-HSCT). However, specific information regarding long-term prognosis and risk factors for late mortality after CD34+ cell-selected allo-HSCT is lacking. We conducted a single-center landmark analysis in 276 patients alive without relapse 1 year after CD34+ cell-selected allo-HSCT for AML (n=164), ALL (n=33) or myelodysplastic syndrome (n=79). At 5 years' follow-up after the 1-year landmark (range 0...

OBJECTIVES: Newer tyrosine kinase inhibitors (TKIs) (bosutinib, ponatinib) and allogeneic hematopoietic stem cell transplantation (allo-HSCT) can be utilized as a salvage therapy in patients with chronic myeloid leukemia (CML) who failed two lines (imatinib → nilotinib or imatinib → dasatinib) of TKI therapy. However, these TKIs are not available in many countries and not all patients can undergo allo-HSCT. METHODS: In this study, CML patients who received dasatinib or nilotinib as a third-line treatment were retrospectively evaluated...

Filgrastim-sndz (Zarxio®) was approved by the FDA in March 2015 as a biosimilar product of its reference product, filgrastim (Neupogen®) for all five indications. The NCCN Clinical Practice Guidelines has incorporated filgrastim-sndz into its recommendations as a category 1 recommendation for use in settings of febrile neutropenia, myelosuppressive chemotherapy administration, and post-hematopoietic stem cell transplant (HSCT). As a cost-saving initiative, our institution switched from filgrastim to filgrastim-sndz for all indications starting in March 2016...

The use of post-transplant cyclophosphamide (PT-Cy) as GvHD prophylaxis has revolutionized haploidentical HSCT, allowing safe infusion of unmanipulated T cell-replete grafts. PT-Cy selectively eliminates proliferating alloreactive T cells, but whether and how it affects NK cells and their alloreactivity is largely unknown. Here we characterized NK cell dynamics in 17 patients who received unmanipulated haploidentical grafts, containing high numbers of mature NK cells, according to PT-Cy-based protocols in two independent centers...

REVIEW
Jessica M Sun, Joanne Kurtzberg
The concept of utilizing human cells for the treatment of medical conditions is not new. In its simplest form, blood product transfusion as treatment of severe hemorrhage has been practiced since the 1800s. The advent of hematopoietic stem cell transplantation (HSCT) began with the development of bone marrow transplantation for hematologic malignancies in the mid-1900s and is now standard of care for many hematologic disorders. In the past few decades, HSCT has expanded to additional sources of donor cells, a wider range of indications, and the development of novel cell products...

PURPOSE OF REVIEW: Mucositis is a severe and common side effect of anticancer treatments, with an incidence of between 40 and 80% depending on the cytotoxic regimen used. The most profound mucositis burden is experienced during conditioning regimens for hematopoietic stem cell transplant (HSCT), where the use of highly mucotoxic agents with or without total body irradiation leads to serious damage throughout the alimentary tract. Currently, the assessment and management of both oral and gastrointestinal mucositis lack authoritative guideline, with recommendations only achieved in narrow clinical scenarios...
