Abstract
Plateletpheresis has become a pivotal part of transfusion medicine. With the increasing demand for plateletpheresis, donor safety is an area of concern because plateletpheresis alters donor hematological parameters. For a better understanding of plateletpheresis, a systemic review is needed to study more evidence-based aspects of plateletpheresis. Electronic databases PubMed, Google Scholar, and Cochrane Library were used to find articles from January 1, 1980, to May 23, 2024. The random effect model was used to meta-analyze the effect of plateletpheresis on hematocrit, hemoglobin, and red blood cell (RBC) count. The Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guideline was followed. A total of 24 studies were found; the effect of plateletpheresis on hemoglobin, hematocrit, and RBC count was studied in the following respective numbers of donors: 3,374, 3,374, and 690. A decrease of hemoglobin, hematocrit, and RBC count was observed after plateletpheresis having a weighted mean difference (WMD) of 0.50 (95%CI = -0.72 to -0.27), WMD of -1.36 (95%CI = -2.05 to -0.66), and WMD of -0.18 (95%CI = -0.23 to -0.12), respectively. Plateletpheresis shows a decrease in the value of hematological parameters such as hemoglobin, hematocrit, and erythrocyte count due to blood loss in the kits employed in the procedure; cell lysis was also seen because of exposure of erythrocytes to stress or change in osmotic pressure. Thus, strict criteria for donation must be developed for better safety of the donors. Improved automated cell separators for plateletpheresis should be made available in blood banks to ensure good quality hematologic products. Our findings suggest that the duration of the procedure should be decreased.

Abstract
Objective This study aimed to analyze the population characteristics of apheresis platelet donors in Chongqing Province and provide a scientific basis for the development of precise and efficient recruitment strategies. The ultimate goal is to increase the number of regular platelet donors in preparation for public health emergencies. Methods This study involved 53,089 blood donors who donated apheresis platelets to the Chongqing Blood Center from 2020 to 2022. Data regarding age, sex, blood type, education level, occupation, and frequency of blood donation were collected and analyzed to identify factors influencing platelet donation. Results Between 2020 and 2022, the majority of apheresis platelet donors in Chongqing were aged 25-35 years, with a male-to-female ratio of 2.6:1. The ABO blood group distribution was O > A > B > AB. The apheresis platelet donors mainly consisted of college students, and the donors who had donated only once accounted for the greatest proportion. Conclusion Based on the population characteristics of apheresis platelet donors in Chongqing, blood collection and supply organizations must refine emergency blood collection and supply plans during public health emergencies. This study underscores the importance of developing precise and efficient recruitment strategies for apheresis platelet donors and expanding the pool of regular apheresis platelet donors. These measures are essential to ensure the timely, safe, and effective use of clinical blood resources during public health emergencies.

Abstract
Background: Eligibility criteria for blood donation require hemoglobin levels of ≥12.5 g/dL for women and ≥13.5 g/dL for men, and a platelet count of ≥180 × 109/L. Screening methods before donation should ensure high accuracy, precision, and ease in operation. We assessed the performance, precision, and repeatability of the Horiba Micros ES 60 (Horiba) compared to the Beckman Coulter DXH 800. Methods: Performance was compared by testing samples for each of the 11 devices across 6 sites in the Transfusion Service of Friuli Venezia Giulia Region, Italy. We measured precision by calculating the coefficient of variation (CV), concordance with ρ-Pearson’s correlation coefficient, and accuracy with F-tests. The intra-assay agreement was examined in the 11 devices, and repeatability was performed by using CV and the Kruskal−Wallis test. Results: The precision of Horiba was acceptable. Overall, ρ-Pearson’s coefficients indicated a strong correlation and positive relationship between all variables. The Bland−Altman plots showed that most of the differences lay within the limits of agreement. All CV were below the reference threshold for all the parameters. Finally, the Kruskal−Wallis test reported non-significant statistical differences for all parameters, except platelet count (p < 0.000). Conclusions: Horiba is adequate for routine pre-donation screening. The intra-assay agreement further demonstrates the accuracy of the device.

Abstract
The increases in major surgeries, transplantations and speciality clinics have significantly increased the utilization of platelet concentrates including single donor platelets (SDP). The advantages of SDP or apheresis platelet have been discussed elaborately by previous authors as compared to random donor platelets. Here we share our experiences of plateletpheresis procedures using the modern apheresis machines with regards to product quality and donor safety. This study included 3016 procedures of plateletpheresis (1397 on Amicus and 1619 on Trima accel cell separators) on eligible donors using recommended apheresis kits. A target yield of 3 × 1011 was set as the end point of each procedure. Donor details, procedure details and donor adverse reactions if any were documented. Statistical analysis was done using the SPSS statistical package (version 13, USA). Of the total 6276 donors screened 2049 (32.6%) were deferred due to various reasons. Out of remaining 4227 eligible donors; 3016 (71.4%) underwent plateletphereis procedures based on the requirement of SDP by the patients. Mean pre-procedure platelet count and hematocrit in donors were 188.3 × 106/mL and 41.7% respectively. Mean procedure time in Amicus (76.6 min) was significantly more than the Trima accel (64.3 min) (p = 0.02). Platelet yield by Trima accel and Amicus was 2.96 × 1011 and 3.08 × 1011 respectively (p = 0.061). A total of 40 donors (1.33%) suffered adverse effect during or after apheresis procedures. While the modern plateletpheresis devices are both donor and user friendly at the same time they provide quality product consistently in lesser time.

The Play of Citrate Infusion with Calcium in Plateletpheresis Donors. Indian J Hematol Blood Transfus 2020; 37:295-301. [PMID: 33867737 DOI: 10.1007/s12288-020-01339-z] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/03/2020] [Accepted: 08/17/2020] [Indexed: 10/23/2022] Open
Abstract
Citrate is the anticoagulant of choice for plateletpheresis. Citrate toxicity is common during plateletpheresis as citrate chelates calcium and causes hypocalcemia in donors. We have conducted this study to analyze the effects of routine citrate infusion during plateletpheresis on laboratory and clinical parameters. We also compared the dose of citrate delivered to donors during plateletpheresis using two different cell separators as Haemonetics MCS + and Trima Accel. The study was conducted on 50 plateletpheresis donors who were eligible for donation. Donor demographics and baseline parameters were recorded. Pre, mid and post-procedure blood samples were collected for hematological and biochemical analysis. We found a significant decrease in baseline iCa (1.23 ± 0.07 mmol/L) from start to mid-procedure (1.19 ± 0.006 mmol/L) which recovered at 30 min post procedure (1.2 ± 0.01 mmol/L). The incidence of citrate toxicity was 10%. In donors with citrate toxicity, the post-procedure recovery of iCa was not seen and there was a further decrease in iCa levels. We also found a significant fall in Hb and platelet count post plateletpheresis. We observed that lower PLT counts (< 200 × 103/µL) necessitated higher blood volume processing and therefore a higher anticoagulant (citrate) dose. The Trima Accel cell separator reached platelet target yield faster but with a higher citrate dose as compared to Hemonetics MCS + . Ionized calcium decreases significantly during plateletpheresis but recovers soon after the completion of the procedure. Serious adverse events were not observed during plateletpheresis. The mild citrate toxicity which occurred was easily managed by slowing the procedure and administering oral calcium to donors. Trima Accel and Hemonetics MCS + both collected platelets efficiently, with minimal donor discomfort.

Abstract
BACKGROUND Single-donor platelets (SDPs) prepared by sophisticated automated equipment offer several advantages over random-donor platelets and are being increasingly used to support thrombocytopenic patients. Different apheresis machines working on the principle of centrifugation are being used worldwide to collect platelets. This retrospective study was done to compare plateletpheresis on two automated cell seperators - Haemonetics® MCS® Plus and Trima Accel®. MATERIALS AND METHODS Data for 100 single-donor plateletpheresis procedures, fifty on each machine, were retrospectively collected and analyzed. Donor characteristics were analyzed by Student's t-test and no significant difference was found between the two groups. The parameters compared between the two machines were yield, collection efficiency, blood volume processed, procedure time, acid-citrate-dextrose (ACD) used, leukodepletion achieved, quality control of the products, and adverse donor reactions. RESULTS Platelet yield (3.054 ± 0.14 vs. 3.120 ± 0.25), quality control of the platelets, leukodepletion achieved, and donor safety were comparable in both the machines. The blood volume processed (2230.74 ± 227.01 vs. 2452.90 ± 318.61), ACD used during procedure (265.48 ± 43.21 vs. 298.10 ± 53.32), procedural time (55.92 ± 13.00 vs. 68.86 ± 12.64), and the postprocedural decrease in donor count in Trima Accel® (183.10 ± 23.99 vs. 161.44 ± 63.47) were significantly less than those in Haemonetics® MCS® Plus. The median collection efficiency of Trima Accel® was found to be greater than Haemonetics® MCS® Plus (0.000649 vs. 0.000608, P = 0.020). CONCLUSION Both Trima Accel® and Haemonetics® MCS® Plus can collect SDPs safely and efficiently. Trima Accel® has higher collection efficiency and reduced incidence of citrate-related adverse effects. It also has better potential to optimize productivity due to decreased procedural time.

Abstract
The apheresis platelets are the preferred blood components for the thrombocytopenic hemato-oncology patients. The one of the important factors for post transfusion increment is the dose of the platelet product infused. The minimum platelet product yield is defined but the amount of maximum possible platelets collection from a single donor is not universally defined. There is lots of apprehension in our country for apheresis procedures harvesting more than a standard unit. This retrospective observational study was conducted to determine safety of high yield plateletapheresis collection among Indian donors This retrospective observational study was conducted for a period of 15 months including all consecutive plateletapheresis procedures. The informed consent had been obtained from all donors including high yield plateletapheresis (Yield ≥ 5 × 1011). The apheresis product was subjected to platelet count. The donor adverse reactions were recorded along with procedural details. Post procedure complete blood count was done for the donors who consented for post procedure blood sample draw A total 569 procedures were performed during this period including 174 high yield procedure. The 526 procedures were analyzed for adverse donor reactions. The 43 were excluded for adverse donor reaction analysis due to yield less than 3 × 1011 (n = 43). The adverse reactions rate between high yield procedures (18/174, 10.34%) and normal yield (20/352, 5.68%) were not statistically different (p = 0.052). The phlebotomy related complication (3.23%) followed by citrate toxicity (2.28%) were the two most common adverse reaction observed. The adverse reactions associated with high yield plateletapheresis procedures are comparable to normal yield procedures in term of overall adverse reactions observed and post procedural platelet counts. This can be beneficial to patients by providing products of greater yield.

Abstract
Background & objectives: The well-being of donors undergoing frequent plateletpheresis has been a matter of concern. The aim of this study was to analyze the effect of frequent plateletpheresis on the haematological parameters (HP) of repeat donors. Methods: The study was conducted during February 2016 to March 2017 on all the repeat plateletpheresis donors undergoing the 2nd plateletpheresis within a month of the first in a tertiary care centre. Donors repeating plateletpheresis 3rd and 4th times were also studied. The values of the HP observed on follow up after plateletpheresis done on three different separators were compared. Results: HPs of the 98 donors were similar at follow up except mean platelet volume (P<0.05). Of the 98 donors, 35 were followed up within a week and 63 were followed up within 8-30 days. No significant alteration was found in the HPs except a significant difference in the variation of platelet counts of the two groups (P=0.025). In 34 donors who presented 3rd time for plateletpheresis (mean gap between 1st and 3rd plateletpheresis=31 days), no significant differences in the HPs were found except the platelet distribution width (P<0.05). Minimal difference in the HP was found in the baseline and the follow up of 3rd plateletpheresis i.e., at 4th plateletpheresis donation. Plateletpheresis through all the three cell separators used had similar effects on the follow up HPs. Interpretation & conclusions: Repeated plateletpheresis can be done without any detrimental effects on the cell counts of the plateletpheresis donors. The three cell separators yielded similar post-donation follow up haematological parameters.

Abstract
The effects of platelet donation by apheresis on different parameters of the erythrogram are still unclear. The objective was to meta-analyze the effect of plateletpheresis on hematocrit, hemoglobin, and erythrocyte count, with a systematic review with random effects meta-analysis of the mean difference. The PRISMA guidelines were considered, as well as 133 search strategies on four different databases. Reproducibility was guaranteed and methodological quality was evaluated. Heterogeneity was evaluated with Galbraith and DerSimonian-Laird’s, publication bias with a funnel plot and a Begg’s test, sensitivity analysis and a cumulative meta-analysis were also conducted. Eighteen (18) articles were included, 17 evaluated the effects on hematocrit in 2,564 donors; 13 on hemoglobin in 1,640 donors; and 4 on red blood cell count in 243 donors. A decrease of 2.26% (CI95% = 2.11–2.41) was observed in hematocrit, of 0.80 g/dL (CI95% = 0.75–0.86) in hemoglobin and −0.21 × 1012/L (CI95% = −0.13; −0.29) in red blood cell count. Plateletpheresis has a negative effect on the erythrogram parameters, explained by blood loss in the kits used for the procedure and cell lysis. Such evidence is relevant to secure the efficiency and safety of the procedure, improve selection processes or determine the number of donations that can be performed without affecting donors’ health.

Abstract
Platelet apheresis units are transfused into patients to mitigate or prevent bleeding. In a hospital, platelet apheresis units are transported from the transfusion service to the healthcare teams via two methods: a pneumatic tubing system (PTS) or ambulatory transport. Whether PTS transport affects the activity and utility of platelet apheresis units is unclear. We quantified the gravitational forces and transport time associated with PTS and ambulatory transport within our hospital. Washed platelets and supernatants were prepared from platelet apheresis units prior to transport as well as following ambulatory or PTS transport. For each group, we compared resting and agonist-induced platelet activity and platelet aggregate formation on collagen or von Willebrand factor (VWF) under shear, platelet VWF-receptor expression and VWF multimer levels. Subjection of platelet apheresis units to rapid acceleration/deceleration forces during PTS transport did not pre-activate platelets or their ability to activate in response to platelet agonists as compared to ambulatory transport. Platelets within platelet apheresis units transported via PTS retained their ability to adhere to surfaces of VWF and collagen under shear, although platelet aggregation on collagen and VWF was diminished as compared to ambulatory transport. VWF multimer levels and platelet GPIb receptor expression was unaffected by PTS transport as compared to ambulatory transport. Subjection of platelet apheresis units to PTS transport did not significantly affect the baseline or agonist-induced levels of platelet activation as compared to ambulatory transport. Our case study suggests that PTS transport may not significantly affect the hemostatic potential of platelets within platelet apheresis units.

The double dose plateletpheresis (DDP) is considered to be a cost effective way of preparing platelets, owing to the low incidence of infectious complications and by also minimizing allogeneic donor exposure to the patients. We aimed at collecting DDP at our center and study its effect on donor hematological parameters, evaluate the product quality and the adverse donor reactions thereafter. Double Dose Platelet was collected from 160 eligible apheresis donors on Amicus cell separator (Fenwal, Inc. Three Corporate Drive Lake Zurich, IL, USA). The donor hematological parameters, product yield, adverse effects on the donors, collection efficiency (CE) and collection rate of the machine were noted. A total of 160 DDPs were collected. The total blood volume processed to achieve the yield of 6.0 × 1011 was 3673.5 ± 276.56 mL. The average yield achieved was 6.14 ± 0.26 × 1011. The average run time was 68.05 ± 6.25 min. Total ACD used was 408.33 ± 33.81 mL. We observed significant relation of pre-donation donor platelet count and platelet yield (p < 0.001). The CE was 78.09 ± 5.15%. There was a significant drop in the post DDP platelet count (p < 0.01) causing no adverse effect. Fourteen donors (8.75%) experienced mild citrate related adverse events. DDP does not lead to major adverse effects and post DDP hematological parameters are also within the acceptable range. It also helps to maintain apheresis platelet inventory, reduce donor exposure, reduce donor requirement and reduce the cost of the product.

Abstract
INTRODUCTION Increase in awareness regarding use of single donor platelets and the availability of technology has resulted in increased platelet pheresis procedures. The interval between two succesive plateletpheresis donations is much less compared to whole blood donations. Plateletpheresis procedures are associated with short term and long term adverse events. The effect of plateletpheresis on haematopoietic system remains significant. AIM To study the recovery of platelet count to baseline in plateletpheresis donors. MATERIALS AND METHODS Fifty, first time apheresis donors were followed for platelet count recovery. Platelet count was measured before donation and at 30 minutes, 48 hours, 7th day and 14th day post-donation. Donor platelet count recovery to baseline was observed during the two week period. Results were analysed statistically, p<0.05 was considered statistically significant. RESULTS Platelet count recovered to baseline by 7th day post-donation in 50% of donors in groups I (Pre-donation platelet count 1.5 lacs/μl to 2.2 lacs/μl) and II (Donors with platelet count >2.2 lacs/μl to 2.75 lacs/μl), 30% of donors in group III (Donors with platelet count >2.75 lacs/μl to 3.5 lacs/μl) of the donors. Donor's platelet count recovered to baseline in 85% of donors by day 14 in across the three groups. Recruitment of platelets from spleen was observed in donors with pre-donation platelet count on the lower limit of normal. CONCLUSION By day 7, donor's platelet count recovered to baseline in majority of the donors. Allowing enough recovery periods for donor platelet count, the minimum interval between two apheresis donations can be 7 days till more prospective studies conclude on the frequency and minimum interval between plateletpheresis donations.

Abstract
BACKGROUND The aim of this study was to evaluate the course of hemoglobin (HGB) concentration and hematocrit (HCT) in donor blood during and after preparatory plasmaphereses (PP) without NaCl and with an infusion of 500 ml 0.9% NaCl during PP. METHODS After informed consent 32 plasma donors were studied in a crossover design. They underwent PP once without NaCl infusion and once, on a different day, with infusion of 500 ml 0.9% NaCl. HGB concentration and HCT values in donor blood were analyzed using a Sysmex KX-21N analyzer. The values of HGB concentration and HCT before PP were set to 100%. Changes in HGB concentration and HCT were calculated in percent directly after PP, and after 24 and 72 h. RESULTS During PP, there was a notable change in HGB concentration (11.2 ± 4.0%) and HCT (11.6 ± 3.9%) in donor blood. The difference between the 2 samples without and with NaCl was highly significant (p < 0.001). After 24 and 72 h, all differences were reduced. CONCLUSION We observed significant changes in HGB concentration and HCT in donor blood during PP. We recommend a concomitant infusion of 500 ml 0.9% NaCl during PP to all donors.
