Effect of donor parameters and cell separators on yield of apheresis platelet and their impact on corrected count increment in aplastic anemia patients. Asian J Transfus Sci 2023; 17:246-250. [PMID: 38274965 PMCID: PMC10807526 DOI: 10.4103/ajts.ajts_146_22] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/01/2022] [Revised: 12/21/2022] [Accepted: 01/08/2023] [Indexed: 01/27/2024] Open
Abstract
BACKGROUND The new cell separators make it simple to collect single donor platelets (SDP), although the platelet yield may vary depending on the cell separator used and donor-related clinical and laboratory variables. AIMS This study aims to study the factors affecting SDP yield and corrected count increment (CCI). MATERIALS AND METHODS This retrospective study was carried out at a tertiary care facility in northern India, over 4 years (May 2017-April 2020), data were retrieved and analyzed. STATISTICAL ANALYSIS Categorical variables were presented as proportions, while continuous variables were presented as mean with standard deviation, P < 0.05 was considered significant. RESULTS We found a positive correlation between predonation platelet count and yield (r = 0.243, P = 0.000). No such significant correlation was found with Hb concentration (r = 0.025, P = 0.720), age (r = 0.016, P = 0.820), sex (r = -0.038, P = 0.584), and weight (r = -0.025, P = 0.714). Maximum platelet yield and minimum time were seen with Trima. Only 39.3% (33/84) meet the 24 h CCI. The majority of patients did not meet the desired CCI could be due to the patients' clinical condition. On logistic regression, we found a significant association of 24 h CCI with product yield (odds ratio [OR] = 0.168, P = 0.015) and posttransfusion platelet count (OR = 0.454, P < 0.05). CONCLUSION The only donor-related factor that influences yield is predonation platelet count, whereas 24 h CCI may depend on the clinical status of the patient and yield.

Abstract
Hyperleukocytosis is a hematologic crisis caused by excessive proliferation of leukemic cells and has a relatively high early mortality due to a series of severe complications. Therefore, prompt and effective intervention is required. Leukapheresis performed using apheresis equipment to separate leukocytes from peripheral blood, at the same time returns autologous plasma, platelets and erythrocytes to the patient, is applied clinically for the treatment of hyperleukocytosis. Leukapheresis not only removes excessive leukocytes rapidly and corrects metabolic abnormalities but also alleviates the symptoms of leukostasis. In addition, the procedure of leukapheresis is generally well tolerated. Leukapheresis has become one of the most imperative adjuvant therapies to treat hyperleukocytosis, especially in the patient who was not inappropriate to cytoreduce with Ara-C or hydroxyurea. In this review, we present the background of leukapheresis development and highlight its clinical application in hyperleukocytic leukemia patients.

A comparative study of five plateletpheresis machines in a tertiary care center of India: AmiCORE vs COM.TEC vs Haemonetics MCS+ vs Spectra Optia vs Trima Accel. J Clin Apher 2020; 36:41-47. [PMID: 32894894 DOI: 10.1002/jca.21838] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/25/2020] [Revised: 07/24/2020] [Accepted: 08/18/2020] [Indexed: 11/08/2022]
Abstract
BACKGROUND Single donor apheresis platelets are superior in quality, but their usage is limited in a developing country due to cost and time constraints. Hence the product obtained must exceed in terms of yield, donor safety and technical convenience. Previous literature available on cell separators is on older versions. AIMS Prospective comparison of 5 latest cell separators (AmiCORE, COM.TEC, Haemonetics MCS+, SpectraOptia and TrimaAccel) for product yield, performance variables and donor adverse effects. MATERIAL & METHODS From October 2019 - March 2020, 1108 donors were randomly allotted to a cell separator. Post-donation sample was taken from the donor 15-20 minutes after procedure completion. The platelet yield from the product collected was measured twice (day 0 and day 1). Donor demography, pre-and post-procedural donor peripheral blood values, performance and product variables were statistically analyzed. RESULTS AmiCORE had an optimal collection efficacy (44.6%) and collection rate (0.037 x 1011/minute). Haemonetics MCS+ had a better collection efficacy (48.4%) and rate (0.038 x 1011/minute). Spectra Optia achieved least procedural time (59.5 minutes), donor adverse effects (6.3%); highest collection efficacy (52.8%) and rate (0.056 x 1011/minute). Trima Accel achieved highest collection rate (0.056 x 1011/minute) and the least product volume (228 ml). CONCLUSION Highest collection efficacy was achieved by Trima Accel, highest collection rate by Trima Accel and Spectra Optia, lowest donor adverse effects by Spectra Optia and least number of procedural troubleshooting by COM.TEC. Apart from this, fiscal factors and service availability also need to be considered before choosing a cell separator.

Abstract
Platelet-rich plasma (PRP) is blood plasma with a high concentration of autologous platelets which constitute an immense reservoir of growth factors. The clinical use of PRP is widespread in various medical applications. Although highly popular with athletes, the use of PRP for the treatment of tendinopathies remains scientifically controversial, particularly due to the diversity of products that go by the name of "PRP." To optimize its use, it is important to look at the various stages of obtaining PRP. In this literature review, we take a closer look at eight parameters which may influence the quality of PRP: 1) anticoagulants used to preserve the best platelet function, 2) the speed of centrifugation used to extract the platelets, 3) the platelet concentrations obtained, 4) the impact of the concentration of red and while blood cells on PRP actions, 5) platelet activators encouraging platelet degranulation and, hence, the release of growth factors, and 6) the use or nonuse of local anesthetics when carrying out infiltration. In addition to these parameters, it may be interesting to analyze other variables such as 7) the use of ultrasound guidance during the injection with a view to determining the influence they have on potential recovery.

Abstract
BACKGROUND With the advantage of easy operation and high reliability, Haemonetics multicomponent collection system (MCS+) is widely used as a blood cell separator in clinical application. OBJECTIVES The aim of this study was to evaluate the effect of technical parameter modification as utilised on the MCS+ to improve the quality of platelet yielded as well as donor comfort. METHODS After informed consent, a total of 118 donors, well matched for baseline parameters, were included in the study from December 2012 to April 2013. Sixty-one donors underwent single-dose plateletpheresis (SDP), and the other 57 donors underwent double-dose plateletpheresis (DDP) before and after technical modification on the MCS+, respectively, according to the manufacturer's instructions. The procedures were evaluated, focusing on whole blood processed (WBP), processing time (PT) and number of cycles were measured, as well as the quality of products. RESULTS No severe adverse reaction was found during donation. WBP, PT and number of cycles after modification were all reduced significantly in both SDP and DDP groups (P < 0·01). In addition, 80·51 % (95 in 118) of the total post-modification products were qualified, presenting with high quality. Besides, the comfort of donors was also improved probably because of the reduced PT. CONCLUSION Adjustment of the relevant technical parameters on MCS+ could produce a beneficial effect on the procedure measures and ensure a high-quality platelet production.

Abstract
Blood component donations by apheresis have become more common in modern blood transfusion practices. We compared three apheresis instruments (Fenwal Amicus, Fresenius COM.TEC, and Trima Accel) with regard to platelet (PLT) yield, collection efficiency (CE), and collection rate (CR). The single-needle or double-needle plateletpheresis procedures of the three instruments were compared in a retrospective, randomized study in 270 donors. The blood volume processed was higher in the COM.TEC compared with the Amicus and Trima. Also there was a significantly higher median volume of ACD used in collections on the COM.TEC compared with the Amicus and Trima. The PLT yield was significantly lower with the COM.TEC compared with the Amicus and Trima. Additionally, the CE was significantly lower with the COM.TEC compared with the Amicus and Trima. There was no significant difference in median separation time and CR between the three groups. When procedures were compared regarding CE by using Amicus device, it was significantly higher in single-needle than double-needle plateletpheresis. When double-needle Amicus system was compared with double-needle COM.TEC system, CE and PLT yield were significantly higher with Amicus system. When single-needle Amicus system was compared with single-needle Trima system, CE and PLT yield were significantly higher with Trima system. All instruments collected PLTs efficiently. However, the CE was lower with the COM.TEC compared with the Amicus and Trima. Also, we found Amicus single-needle system collected PLTs more efficiently compared with the double-needle system. CE and PLT yields were significantly higher with the single-needle Trima instrument compared with the single-needle Amicus device.

Abstract
OBJECTIVE To compare the Fenwal Amicus and the Fresenius COM.TEC apheresis instruments regarding donor peripheral blood parameters, operational variables of the instruments, and quality control parameters of the product obtained. METHODS We performed 100 platelet collections from 100 voluntary donors using the 2 studied devices. We measured platelet count using an automated analyzer and analyzed the activation statuses using a flow cytometer. RESULTS The median time needed to perform the procedures was significantly longer with the COM.TEC. However, the product we obtained using the Amicus instrument showed higher degrees of platelet-activation. All products we obtained with both instruments had white blood cell counts of less than 5 × 10(6) per bag. We observed no statistical difference regarding collection efficiency and collection rates between the devices. CONCLUSION Both instruments collected platelets efficiently, with minimal donor discomfort. Compared with the COM.TEC instrument, the Amicus reached the platelet target yield more quickly; however, it displayed an increase in platelet activation.

Abstract
OBJECTIVE The quality of platelet concentrates (PC) is important for the in vivo recovery of thrombostasis in patients suffering from bleeding disorders and in tumor patients after chemotherapy. In this respect, activated platelets (PLT) cannot display their full functionality in the recipient and even can cause adverse effects. Therefore, we developed a transmission electron microscopy (TEM) method for quality assessment of PC. METHODS Score values taken from panorama TEM images describe the progress of PLT activation. To exemplify this method, i) 19 apheresis PC isolated with the Baxter Amicus system (BA) were compared with 14 PC obtained from pooled buffy coats (BC). ii) The score values of 33 PC derived from BA as well from BC were compared with flow-cytometric CD62P determinations by cross correlation. iii) Changes in the score value profiles during storage of a single pathogen-reduced BA PC were monitored over a period of 7 days. RESULTS The TEM evaluation described allows for demonstrating particular PLT activation stages. i) Significant differences between the percentages of the score values 0, 1 and 2 could be demonstrated in both processing groups. No significant differences were found comparing these two groups. ii) A weak correlation could be shown when comparing the percentages of score values 2 plus 3 with the percentage of CD62P-positive PLT. iii) The pathogen reduction affected slightly the score profiles during storage due to an increase of dead PLT. CONCLUSION Our investigations demonstrate the unique detailed quality information of PC obtained by the TEM method. This method can be performed in every routine electron microscopy laboratory.
