BACKGROUND: The composition of the graft used for allogeneic hematopoietic stem cell transplantation (HSCT) is important for the treatment outcome. Different apheresis devices may yield significant differences in peripheral blood stem cell graft cellular composition. We compared stem cell grafts produced by Cobe Spectra (Cobe) and Spectra Optia (Optia) with use of the mononuclear cell (MNC) protocol, and evaluated clinical outcome parameters such as graft-versus-host disease (GvHD), transplant-related mortality (TRM), relapse, and overall survival...

Bortezomib-based induction is often used in transplant-eligible patients with myeloma. The optimal peripheral blood stem cell (PBSC) mobilisation strategy in this context is unclear. We reviewed the efficacy of G-CSF alone (G-alone) vs. G-CSF and cyclophosphamide (G-cyclo: standard dose: 1.5-2 g/m2 ; high dose: 3-4 g/m2 ) PBSC mobilisation strategies in 288 patients who only received bortezomib, cyclophosphamide and dexamethasone (VCD) induction prior to autograft across six apheresis centres from November 2012 to June 2017...

BACKGROUND AIMS: For patients needing allogeneic stem cell transplantation but lacking a major histocompatibility complex (MHC)-matched donor, haplo-identical (family) donors may be an alternative. Stringent T-cell depletion required in these cases to avoid lethal graft-versus-host disease (GVHD) can delay immune reconstitution, thus impairing defense against virus reactivation and attenuating graft-versus-leukemia (GVL) activity. Several groups reported that GVHD is caused by cells residing within the naive (CD45RA+ ) T-cell compartment and proposed use of CD45RA-depleted donor lymphocyte infusion (DLI) to accelerate immune reconstitution...

INTRODUCTION: Invariant natural killer T cells (iNKTs) are a rare but vital subset of immunomodulatory T cells and play an important role in allogeneic hematopoietic stem cell trans-plantation (HSCT). The association of donor characteristics with the number and frequency of the iNKTs subsets in allografts remains poorly understood. In this paper, we prospectively investigate the association of donor characteristics with iNKTs dose and frequency in granulocyte-colony-stimulating factor (G-CSF) mobilized marrow and peripheral blood harvests...

Cellular collection is an important and increasingly used apheresis procedure. These collections are performed by leukocytapheresis, a procedure involving the removal of a patient's or donor's white blood cells, and are used to collect hematopoietic progenitor cells, specific cell populations (such as T-lymphocytes), and granulocytes. Hematopoietic progenitor cell apheresis and T-lymphocyte collection are performed by procedures that enrich for mononuclear cells. Hematopoietic progenitor cells are used for autologous and allogeneic hematopoietic stem cell transplantation, whereas T-cell collection is being used increasingly in novel cellular therapy approaches and for donor lymphocyte infusions to induce graft-versus-leukemia effect...

Autologous stem cell transplantation (auto-HSCT) is an effective treatment strategy for hematological malignancies. The standard mode of handling hematopoietic progenitors for the autologous procedure (CRYO) consists on its collection and freezing with dimethyl sulfoxide (DMSO) and its subsequent thawing and re-infusion. This process is toxic and expensive. Non-cryopreserved (non-CRYO) is a less expensive mode of auto-HSCT. We designed a comparative study between both strategies performed in two different centers to analyze the short-term complications...

BACKGROUND: Recent research has demonstrated that circulating peripheral blood mononuclear fractions (PBMC) containing haematopoietic stem (HSC)/progenitor cells have the potential to play a crucial role in regenerative medicine strategies. Work in our laboratory has shown that a peripheral blood mononuclear cell fraction (PBMC) enhances cartilage repair in an osteochondral defect model in sheep and has a significant effect on cells in the joint niche. In order to obtain PBMC rich blood containing HSCs for further studies, we have performed, for the first time, apheresis on adult sheep...

Allogeneic hematopoietic stem cell transplantation (HSCT) with reduced intensity conditioning (RIC) offers a curative option for patients with hematologic malignancies who are unable to undergo myeloablative conditioning, but its success is limited by high rates of relapse. Several studies have suggested a role for T-cell doses in peripheral blood stem-cell grafts in RIC HSCT. Since T-cell dose is typically not known until after the collection, and apheresis blood volume is easily modifiable, we hypothesized that higher donor apheresis blood volumes would improve transplant outcomes through an effect on graft composition...

We investigated the effects of CD34+cell therapy on right ventricular (RV) function in patients with nonischemic dilated cardiomyopathy (DCM). We enrolled 60 patients with DCM who were randomized to CD34+cell therapy (Stem Cells (SC) Group n = 30), or no cell therapy (Controls, n = 30). The SC Group received granulocyte-colony stimulating factor, and CD34+cells were collected by apheresis and injected transendocardially. Patients were followed for 6 months. At baseline, the groups did not differ in age, gender, left ventricular ejection fraction, N-terminal probrain natriuretic peptide, or parameters of RV function...

BACKGROUND: Autologous peripheral blood hematopoietic stem cell (PBSC) collection efficiency (CE) is reportedly affected by the patient's blood properties; however, studies to identify factors correlated with CE have shown inconsistent results. Additionally, variables such as stem cell graft granulocyte content and patient age, sex, and underlying disease, may be associated with hematopietic stem cell (HSC) infusion-related adverse reactions. In this study, we evaluated the correlation of preleukapheresis PB granulocyte count and PBSC harvest variables with CD34+ collection yield and efficiency, and thawed HSC infusion side effect occurrence...

INTRODUCTION: Administration of Filgrastim (rhG-CSF) (Neupogen®) in healthy donors to mobilize hematopoietic stem cells (HSC) is a widespread practice in adults. Application of peripheral blood stem cell (PBSC) collection in normal pediatric donors is scarce due to ethical issues. Hence, there are insufficient data on the long-term impact of PBSC procedure in healthy children. This retrospective study aimed to evaluate the early and late adverse effects of PBSC donation in pediatric donors...

We conducted a prospective study on T and natural killer (NK) cell subset composition of graft and transplant outcomes in T cell-replete haploidentical transplantation with a single dose of subcutaneous plerixafor (Px) added to granulocyte colony-stimulating factor (G-CSF)-based mobilization in allogeneic donors to collect 10 × 106 /kg CD34+ hematopoietic stem cells (HSCs) at single apheresis. Twnety-six donors received G-CSF + Px and 25 G-CSF alone for mobilization. Despite significantly lower peripheral blood (PB) CD34+ HSCs on day 4 in the G-CSF + Px group (33 [range, 6-47] cells/µL versus 81 [range, 50-168] cells/µL in the G-CSF group; P = ...

Allogeneic peripheral blood stem cell (APBSCs) transplantation is an effective treatment for hematological malignancies. However low-weight donor children meet some complications. In the current report, PBSCs were harvested from a 14-month-old child (9.8Kg) for a 6years old sibling recipient suffering from pre-B type of acute lymphoblastic leukemia (ALL) and also 24 months old male child donor (12Kg) for a haploidentical recipient suffering from acute myeloid leukemia (AML-M4EO). The PBSC harvesting was performed using Spectra™ Optia(®) apheresis software with continuous mononuclear cell (CMNC) procedure...

Since the demonstration that hematopoietic cells are present in circulating blood, peripheral blood stem cell transplantation (PBSCT) has become an area of interest. The invention of growth factors such as the granulocyte colony-stimulating factor (G-CSF) and the availability of apheresis techniques allowed the wide application of peripheral blood stem cells (PBSC) in both autologous and allogeneic hematopoietic stem cell transplantation settings. It has been since 1986 that clinically introduced, peripheral blood stem cells replaced bone marrow as a stem-cell source to nearly 100% in the autologous and to approximately 75% in the allogeneic transplantation setting...
