Hematopoietic stem cell transplantation is a curative treatment for many hematologic malignancies with its most important side effect being graft-versus-host disease (GVHD). Herein, we present a 3.5 year-old male with weight of 9.8 kg with acute GVHD (grade IV gastrointestinal and cutaneous) who did not respond to the first line therapies (corticosteroids). Thus, the patient was a candidate for extracorporeal photochemotherapy (ECP). Due to the hyperbilirubinemia, two sessions of ECP every week as well as one session of plasmapheresis 24 h before each ECP session were performed (Spectra™ Optia® apheresis system)...

BACKGROUND: Recently, novel protocol utilizing Continuous Mononuclear Cell Collection (cMNC) have been introduced for leukapheresis. We compared the efficacy of cMNC with an older protocol - mononuclear cell collection (MNC) for CD34+ cell collection in unrelated donors with negative stem cell collection predictors. MATERIAL AND METHODS: Retrospective data from a series of 258 consecutive unrelated hematopoietic stem cell donors was included in this single-center study (80 donors collected with cMNC and 178 with MNC)...

Pediatric peripheral blood stem cell collection (PBSC) is challenging because it has potentially more side effects than in adults due to the small body mass and unique physiology of children. The extracorporeal volume of the cell separator device, poor venous access and metabolic complications due to citrate toxicity are the main problems to face during PBSC collection. These aspects are more relevant in very low body weight (BW) children of 20 kg or lower. An efficient, experienced and well-prepared team of pediatricians, apheresis physicians and nurses, and physicians involved in CVC positioning is crucial to performing a safe PBSC collection...

BACKGROUND: Bone marrow disorders encompass a group of diseases characterised by reduced production of red cells, white cells, and platelets, or defects in their function, or both. The most common bone marrow disorder is myelodysplastic syndrome. Thrombocytopenia, a low platelet count, commonly occurs in people with bone marrow failure. Platetet transfusions are routinely used in people with thrombocytopenia secondary to bone marrow failure disorders to treat or prevent bleeding. Myelodysplastic syndrome is currently the most common reason for receiving a platelet transfusion in some Western countries...

Background: Cytomegalovirus(CMV)-related diseases are a serious cause of morbidity and mortality following hematopoietic stem cell transplantation (HSCT). CMV-specific cytotoxic T lymphocytes (CMV-CTLs) have been reported as an alternative to antiviral drugs that provide long-term CMV-specific immunity without major side effects. However, their application has been limited by the prolonged manufacturing process required. Methods: In this study, we applied the IFN-γ cytokine capture system (CCS) using the fully automated CliniMACS Prodigy device for rapid production of CMV-CTLs, which may be applicable in clinically urgent CMV-related diseases...

BACKGROUND: Mesenchymal stem cells (MSCs) produced for clinical purposes rely on culture media containing fetal bovine serum (FBS) which is xenogeneic and has the potential to significantly alter the MSC phenotype, rendering these cells immunogenic. As a result of bovine-derived exogenous proteins expressed on the cell surface, MSCs may be recognized by the host immune system as non-self and be rejected. Platelet lysate (PL) may obviate some of these concerns and shows promising results in human medicine as a possible alternative to FBS...

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...

REVIEW
Anand Padmanabhan
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. Because 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 transplantation 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...
