Introduction

Most common source of stem cell graft for both autologous and allogenic haematopoietic transplants are peripheral blood haematopoietic progenitor stem cells. Adequate collection of the CD34+ cells and safety of the allogenic donor during the leukapheresis are of prime importance to an apheresis physician. Our retrospective analysis is a comparison between of two platforms namely, COBE Spectra and Amicus, for CD34+ mononuclear cell collection.

Material and method

The study included the data of GSCF (Granulocyte-Colony-Stimulating Factor) mobilized allogenic PBSC collections at our centre from January 2015 to June 2016. The apheresis platforms used were COBE Spectra and Amicus. Blood cell counts were done using LH750 Beckman Coulter (Florida, Miami, USA). CD45+ & CD34+ cell counts were done using BD FACS Canto-II Flow-Cytometer by ISHAGE guidelines.

Results

A total of 170 PBSC (100 COBE Spectra & 70 Amicus) harvests were done on 143 donors, of which 116 completed the collection in a single session and 27 required a second session. Demographic details and pre harvest peripheral blood counts for both the groups did not show any statistical differences. Amicus processed higher blood volume with higher ACD exposure and procedure time compared to COBE Spectra. Higher platelets loss was with COBE Spectra harvests with higher product volumes collection. Collection efficiency (CE2), collection ratio, CD34+ cells dose was similar on both the platforms. RBC contamination, absolute lymphocyte and monocytes counts were significantly higher with Amicus harvest product compared with COBE Spectra. A total of 14 (8.2%; citrate toxicity) adverse reactions were reported out of 170 allogenic PBSC collections.

Discussion/conclusion

Our study suggests that both Amicus and COBE Spectra platforms offer comparable results for allogenic PBSC collections. Amicus offers a concentrated PBSC product with lesser volume and platelets loss but higher RBC contamination.  相似文献

Peripheral blood stem cells (PBSC) are the source of allogeneic hematopoietic stem cell transplants currently used for malignant and non-malignant hematological diseases. PBSC harvest may be difficult in young children who are donors. Extracorporeal separator line priming by red blood cells or albumin alone is usually required to improve haemodynamic tolerance and efficacy of collection. We present our experience with 29 children weighing 20 kg or less mobilised between January 2005 and June 2018. The median age and weight at the time of apheresis were 5 years and 18 kg, respectively. A total of 54 PBSC were performed. The median cell yield per apheresis was 5.9 × 106 CD34+cells/kg (2,5-13,9) recipient body weight (RBW). Despite their low weight, insertion of a femoral catheter was avoided in 58.6% of children. Nineteen donors required 2 or 3 apheresis sessions without any major complication. Twenty-nine pts with hemopathies have successfully benefited from PBSC except one case of rejection with aplastic anemia.  相似文献

BackgroundThe collection of a sufficient number of stem cells is important for success of allogeneic hematopoietic stem cell transplantation (HSCT). This study aimed to investigate the factors associated with successful allogeneic peripheral stem cell (PBSC) collection in healthy donors.MethodsWe retrospectively reviewed clinical data of allogeneic PBSC collection in 175 donors from 2007 to 2017 at the National Cancer Center, Korea. This study analyzed factors associated with the CD34+ cell yield such as the characteristics of donors, including age, laboratory results before apheresis, and data of procedures on the first day. The CD34+ cell dose of ≥ 4.0 × 106/kg have recently been the accepted minimum recommended dose in allogeneic HSCT settings, and this was the target dose in our study.ResultsThe factors associated with the CD34+ cell yield were age (p = 0.007), baseline platelet (PLT) (p = 0.014), and pre-collection hematopoietic progenitor cells (HPCs) (p = 0.001) by multivariate analysis. This study represented that age, baseline platelet count, and pre-collection HPC count are important predictive factors as shown in other previous studies.ConclusionOur data suggest that young age, high baseline platelet counts and high HPC counts before collection might be useful for identifying successful mobilizers.  相似文献

IntroductionRecently, we identified a huge discrepancy between the collection practice and the actual utilization of cryopreserved peripheral blood stem cells (PBSCs) for high-dose chemotherapy (HDCT) and autologous blood stem cell transplantation (ABSCT). Specifically, patients with Burkitt lymphoma, acute leukemia, and myeloproliferative neoplasms (MPN) were frequently not referred for ABSCT after successful PBSC collection.ObjectiveThe aim of this study was to identify variables that are associated with the non-utilization of PBSC grafts.MethodsWe retrospectively analyzed the collection, storage, and disposal of PBSC grafts in Burkitt lymphoma (n = 18), acute lymphoblastic leukemia (ALL, n = 22), MPN (n = 18), and acute myeloid leukemia (AML, n = 71) patients. Patients who underwent autologous PBSC collection at 2 collection and transplantation centers between 2001 and 2012 were included and followed up until 2016.ResultsNone of the Burkitt lymphoma patients were referred for ABSCT. Only in 1 (6%) patient, the graft was discarded after the patient''s death. In all other patients (n = 17, 94%), the grafts were stored independently of the patient''s status (death, n = 4, 22%; no follow-up, n = 6, 33%; no indication for ABSCT given, n = 7, 39%). In ALL patients, 4 (18%) patients underwent ABSCT after a median follow-up of 74 (1–182) months. In the remaining patients, PBSC grafts were either discarded (8 patients, 36%) or stored until the reference date (10 patients, 45%). Seven of 18 MPN patients (39%) underwent ABSCT. ABSCT was performed in 24 (34%) AML patients. In 20 (28%) patients who were not referred to ABSCT, an allogeneic transplantation (TPL) was performed. Fifteen (21%) patients received palliative care or deceased, and their grafts were discarded in all but 1 patient. Additional grafts were discarded in 21 (31%) patients and stored in 9 (13%) patients who underwent ABSCT or allogeneic TPL (n = 44).ConclusionsAs the role and efficacy of autologous HDCT/ABSCT are not established in the analyzed entities, the indication for PBSC collection should be reanalyzed in regular intervals. Moreover, PBSC grafts from patients who have deceased, have insufficient grafts, or have already undergone an allogeneic TPL should be considered for disposal or (if applicable) for research use, to economize storage costs on a rational basis.  相似文献

Allogeneic Hematopoietic Cell Transplantation is a curative approach in various malignant and non-malignant disorders. The majority of adult transplants in the current era are performed using mobilized stem cells, harvested from the peripheral blood by leukapheresis. Peripheral blood stem cell (PBSC) collections are designed to target a dose of stem cells that will result in safe engraftment and hematopoietic recovery; however, 99 % of the cells contained in a PBSC graft are not stem cells and a growing number of studies attempt to characterize the associations between graft composition and transplant outcomes. A better understanding of the impact of the quantity and quality of various cell types in PBSC grafts may lead to development of novel collection strategies or improved donor selection algorithms. Here we review relevant findings from recent studies in this area.  相似文献
