BACKGROUND AND AIMS: The infusion of enriched CMV-specific donor T-cells appears to be a suitable alternative for the treatment of drug-resistant CMV reactivation or de novo infection after both solid organ and hematopoietic stem cell transplantation. Antiviral lymphocytes can be selected from apheresis products using the CliniMACS Cytokine-Capture-System(®) either with the well-established CliniMACS(®) Plus (Plus) device or with its more versatile successor CliniMACS Prodigy(®) (Prodigy)...

BACKGROUND: Hematopoietic progenitor stem cell transplantation (HPSCT) is used as a standard treatment option to improve outcome in hematological and nonhematological disorders. It is important for new HPSCT program to look at its patient outcome data and compare it with the published data to evaluate the efficacy of program. AIMS: The aim was to compile and collate the patient outcome data of HPSCT and compare with published reports. MATERIALS AND METHODS: Patient demographics, indications, stem cell harvest by apheresis, dose collected, infusion, engraftment, and follow-up data were collected from hospital information system from 2010 to 2013 in a tertiary care hospital...

BACKGROUND: A second allogeneic hematopoietic stem-cell transplantation and donor lymphocyte infusion using cells from the same donor is a therapeutic option in the case of stem-cell graft failure or disease relapse, but little is known about the factors associated with the CD34(+) cell yields from second donations. METHODS: One-hundred healthy donors who underwent a second mobilization treatment and peripheral blood stem-cell (PBSC) collection were studied. For both mobilization processes, 5 µg of granulocyte colony-stimulating factor per kg per day was administered...

BACKGROUND: High-dose chemotherapy with autologous stem-cell transplantation (asct) is an accepted part of standard therapy for patients with hematologic malignancies. Usually, stem-cell mobilization uses granulocyte colony-stimulating factor (g-csf); however, some patients are not able to be mobilized with chemotherapy and g-csf, and such patients could be at higher risk of failing mobilization. Plerixafor is a novel mobilization agent that is absorbed quickly after subcutaneous injection and, at the recommended dose of 0...

The capacity of natural killer (NK) cells to recognize and kill transformed cells suggests that their infusion could be used to treat cancer. It is difficult to obtain large numbers of NK cells ex vivo by exposure to cytokines alone but the addition of stimulatory cells to the cultures can induce NK cell proliferation and long-term expansion. Some of these methods have been validated for clinical-grade application and support clinical trials testing feasibility and safety of NK cell administration. Early data indicate that ex vivo expansion of NK cells from healthy donors or from patients with cancer is robust, allowing multiple infusions from a single apheresis...

BACKGROUND AIMS: Leukapheresis products for hematopoietic stem cell transplantation can be cryopreserved for various indications. Although it is known that CD34(+) cells tolerate cryopreservation well, a significant loss of CD3(+) cells has been observed, which has been ascribed to several factors, including transport, storage conditions and granulocyte-colony stimulating factor (G-CSF) administration. METHODS: To assess the tolerance of CD34(+) cells and lymphocyte subpopulations for cryopreservation and thawing, the post-thaw recoveries of CD34(+) cells, CD3(+)CD4(+) cells, CD3(+)CD8(+) cells, CD19(+) cells and CD16(+)CD56(+) cells were determined in 90 cryopreserved apheresis products, among which 65 were from G-CSF-mobilized donors, and 34 from unrelated donors that underwent transport before cryopreservation at our center...

Chemotherapeutic agents without cross-resistance to prior therapies may enhance PBSC collection and improve patient outcomes by exacting a more potent direct antitumor effect before autologous stem cell transplant. Bendamustine has broad clinical activity in transplantable lymphoid malignancies, but concern remains over the potential adverse impact of this combined alkylator-nucleoside analog on stem cell mobilization. We performed a prospective, nonrandomized phase II study including 34 patients with multiple myeloma (MM) (n=34; International Staging System (ISS) stages I (35%), II (29%) and III (24%); not scored (13%)) to evaluate bendamustine's efficacy and safety as a stem cell mobilizing agent...

BACKGROUND: Stem cell transplantation is an emerging method of treatment for patients with cardiovascular disease. There are few studies completed or ongoing on stem cell therapy in patients with idiopathic dilated cardiomyopathy (IDCM). Information on stem cell homing and distribution in the myocardium after transplantation might provide important insight into effectiveness of transplantation procedure. AIM: To assess early engraftment, retention and migration of intracoronarily transplanted stem cells in the myocardium of patients with advanced dilated cardiomyopathy of non-ischaemic origin using stem cell labeling with (99m)Tc-exametazime (HMPAO)...

Autologous hematopoietic stem cell transplantation (auto-HSCT) provides hematopoietic support after high-dose chemotherapy and is the standard of care for patients with multiple myeloma (MM), chemo sensitive relapsed high or intermediate grade non-Hodgkin's lymphoma (NHL) and Hodgkin's lymphoma (HL). However, yields of hematopoietic stem cells vary greatly between patients, and the optimal strategy to mobilize hematopoietic stem cells into peripheral blood for collection has not been defined yet. We investigated the efficacy and safety of chemo mobilization with an intermediate dose etoposide (VP-16; 200 mg/m(2) on days 1-3) and granulocyte-colony stimulating factor (G-CSF)(5 µg/kg twice daily from day 4 through the final day of collection)...

Allogeneic stem cell transplantation is an effective treatment for high-risk myeloid malignancies, but relapse remains the major post-transplantation cause of treatment failure. Alloreactive natural killer (NK) cells mediate a potent antileukemic effect and may also enhance engraftment and reduce graft-versus-host disease (GVHD). Haploidentical transplantations provide a setting in which NK cell alloreactivity can be manipulated, but they are associated with high rates of GVHD. We performed a phase I study infusing escalating doses of NK cells from an HLA haploidentical-related donor-selected for alloreactivity when possible-as a component of the preparative regimen for allotransplantation from a separate HLA-identical donor...

BACKGROUND: Harvest of hematopoietic progenitor cells via leukapheresis is being used increasingly for transplants in India. Adequate yield of cells per kilogram body weight of recipient is required for successful engraftment. Collection efficiency (CE) is an objective quality parameter used to assess the quality of leukapheresis program. In this study, we calculated the CE of the ComTec cell separator (Fresenius Kabi, Germany) using two different formulae (CE1 and CE2) and analyzed various patient and procedural factors, which may affect it...

Introduction Multiple sclerosis (MS) is a T-cell-mediated chronic inflammatory disorder of the central nervous system. Several agents have been approved for treatment of MS, however their efficacy is limited and short term. Autologous hematopoietic stem cell (HSC) transplantation may remain an encouraging option for some MS patients who failed prior conventional treatment. Objective To assess the safety and effectiveness of HSCs mobilization in patients with MS. Material and methods Thirty-nine patients (20 females, 19 males) with relapsing-remitting MS at median age of 40 years (range 25-63) were included in this study...

Granulocyte colony-stimulating factor (G-CSF) mobilized peripheral haematopoietic progenitor cells collected by apheresis (HPC-A) are the most common source used for allogeneic hematopoietic stem cell transplantation (HSCT). Retrospective short and long-term donor follow-up studies show very low risks of serious complications and do not report compelling evidence of increased cancer occurrence. Some studies reported a prolonged period of leucopenia without an obvious association with infectious complications...

The most commonly used stem cell source for both autologous and allogeneic transplantation is mobilized peripheral blood hematopoietic progenitor cells collected by apheresis. In the 1990s, an Italian group used the correlation between the preapheresis peripheral blood CD34+ cell count and the final number of CD34+ cells collected to devise a formula for "target value-tailored" (TVT) apheresis. Using local patient data, the Canadian Blood Services Stem Cell Laboratory created a similar model to determine the blood volume to process during apheresis collection...

PURPOSE OF REVIEW: Allogeneic hematopoietic stem cell transplantation (HSCT) is still partially ineffective in curing high-risk hematological malignancies, with estimates of relapse rates ranging from 40 to 50%. The purpose of this review is to discuss the emerging therapeutic options for patients with relapsed disease following HSCT based on adoptive immunotherapy using donor-derived T cells genetically engineered to express CD19-specific chimeric antigen receptors (CARs). RECENT FINDINGS: Adoptive cell therapy (ACT) with CAR-modified T cells represents an attractive therapeutic option for further enhancing the graft-versus-leukemia effect...

We retrospectively reviewed the results of cyclophosphamide (3 g/m(2) ), doxorubicin and dexamethasone plus granulocyte-colony stimulating factor (G-CSF) (ID-CY/DOX group), low-dose cyclophosphamide (2 g/m(2) ) plus G-CSF (LD-CY group) and G-CSF alone (G-CSF group) for stem cell mobilization in patients with multiple myeloma. A total of 89 patients with 93 mobilizations were included. Apheresis was started when total white blood cell (WBC) count >10 × 10(9) /L for ID-CY/DOX and LD-CY groups and after eight doses of G-CSF (5 μg/kg twice daily) for G-CSF group...

Autologous hematopoietic stem cell transplantation is the standard therapy for refractory/relapsed aggressive lymphoma. The initial step of the procedure involves mobilization and collection of hematopoietic stem cells. G-CSF fails to achieve mobilization in 15-25% of lymphoma patients. Plerixafor is a novel CXCR4 antagonist that can promote mobilization. It has been used successfully in patients after the failure of G-CSF. It is reasonable to test whether plerixafor should become the mobilizing agent of choice in patients expected to exhibit difficulties in mobilization...

Mesenchymal stromal cells (MSCs) possess a multi-lineage potential and immunoregulatory activities and provide a great potential in cell-based technologies. However, MSC suppressive activity raises concerns regarding the possible adverse effect of MSCs on the immune recovery. The influence of autologous MSC co-transplantation on recovery of T cell subsets in patients receiving autologous hematopoietic stem cell transplantation (AHSCT) for malignant lymphomas and multiple myeloma were characterized. Co-transplantation of MSCs improved lymphocyte recovery most effectively in patients with low input of hematopoietic stem cells or low absolute lymphocyte count in apheresis product...

Today, hematopoietic stem cell transplantation (HSCT) is a standard treatment for a variety of conditions in children, including certain malignancies, hemoglobinopathies, bone marrow failure syndromes, immunodeficiency and inborn metabolic disease. Two fundamentally different types of HSCT are categorized by the source of the stem cells. The first, autologous HSCT represents infusion of patient's own hematopoietic stem cells (HSCs) obtained from the patient; the second, allogeneic HSCT refers to the infusion of HSCs obtained from a donor via bone marrow harvest or apheresis...
