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
Background There is a need for platelet products to have the best quality. Apheresis platelet concentrates (PCs) obtained from single-donors PCs (SD-PCs) are considered best but have issues such as feasibility and cost. Buffy-coat pooled PCs (BCP-PCs) are considered an alternative to SD-PCs. This study compares BCP-PCs and SD-PCs for in vitro quality parameters and their changes during storage. Materials and Methods Fifteen units of BCP-PCs and 15 units of SD-PCs were prepared. In this study, a pool of five buffy coats was prepared. Fifteen units of BCP-PCs were analyzed on day 1 and day 5 of storage, while 15 SD-PCs were analyzed on day 1 while ten units on day 5. The parameters analyzed were volume, hematological parameters, pH, swirling, and sterility. Results The mean platelets count of SD-PCs was found to be significantly higher as compared to BCP-PCs. White blood cells (WBCs) contamination was significantly lower in BCP-PCs as compared to SD-PCs. The mean pH and mean platelet volume of SD-PCs were significantly lower than BCP-PCs. During storage, the mean platelets count of BCP-PCs was decreased significantly while that of SD-PCs nonsignificantly. The mean WBCs count and pH decreased in both BCP-PCs and SD-PCs significantly. All units in both types of PCs were sterile. Conclusion Platelet yield was significantly better in SD-PCs, while mean WBCs contamination was significantly lower in BCP-PCs. BCP-PCs may be preferred in place of SD-PCs in case of nonavailability of apheresis, difficulty in finding a willing donor, or when the cost is of consideration.

Abstract
INTRODUCTION The donor deferral criteria for blood or apheresis donations are established for two main reasons: (i) to ensure the safety of the blood donor (non-maleficence); (ii) to obtain safe blood of standard quality that has therapeutic benefit for the patient (beneficence). This study was planned to assess the various causes and patterns of plateletpheresis donor deferral in our hospital and to subsequently assess whether any evidence based changes can be done in the current plateletpheresis donor deferral criteria in India to maximize the platelet donor pool without compromising donor safety. MATERIAL AND METHODS The present study was conducted from May 2021 till June 2022 in the department of transfusion medicine of a tertiary care hospital in North India. The first part of the study was conducted from May 2021 till March 2022 to assess the various causes of donor deferral by analysing the plateletpheresis donor deferral data during the corresponding period. The second part of the study was conducted from April 2022 till June 2022, to assess: (i) average decrease in haemoglobin after plateletpheresis procedure; (ii) red blood cell loss during plateletpheresis procedure; (iii) to determine whether any correlation exists between donor haemoglobin and platelet yield. RESULTS During the study period, a total of 260 donors were screened for plateletpheresis, out of which 221 (85%) donors were accepted and 39 (15%) donors were deferred for various reasons. Out of the 39 deferred donors, 33 (84.6%) were temporary deferrals, while 6 (15.4%) were permanent deferrals. Low haemoglobin (Hb < 12.5 g/dl) was a cause of deferral in 12.8% (n = 5) of the deferred donors. 192 (73.9%) out of the 260 donors were replacement donors. The calculated mean decrease in haemoglobin as a result of plateletpheresis procedure was 0.4 g/dl. No correlation was seen between donor pre-donation haemoglobin and platelet yield (p = 0.86, r = 0.06, R2 = 0.003). The calculated mean red cell loss as a result of plateletpheresis procedure was 28 ml. CONCLUSION Low haemoglobin (<12.5 g/dl) is a significant cause of temporary plateletpheresis donor deferral in India. In view of the advancement in plateletpheresis technology, which has resulted in minimal red cell loss with the current generation apheresis devices, haemoglobin cutoff of 12.5 g/dl needs to be reconsidered. Perhaps, after performing a multi-centric trial, a consenscus can be reached for revision of haemoglobin cutoff for plateletpheresis donations.

Abstract
BACKGROUND Increasing demand of single donor platelet requires blood banks to expand the donor pool. A reassessment of donor deferral criteria for plateletpheresis is required to ensure that this increasing demand is met without compromising on product quality and donor safety. AIMS (1) To list the various causes of SDP donor deferral. (2) To discuss various approaches to minimize it. MATERIALS AND METHODS Data of plateletpheresis donor deferral were collected from records retrospectively over a period of 4 years from January 2017 to December 2020. STATISTICAL ANALYSIS All statistical tests were performed using IBM SPSS software for Windows version 20. Categorical variables were presented as proportions, while continuous variables were presented as mean with standard deviation, mean calculated P < 0.05 was considered statistically significant. RESULTS Out of the 7478 donors screened for plateletpheresis procedure, 3232 (43.2%) were deferred among which 3089 (42.5%) were male and 142 (63.1%) were female donors. Majority (96.5%) of deferral were temporary. These included low platelet count (47.4%) followed by poor venous access (22.4%) and low hemoglobin (Hb) (7.2%). Among the donors deferred for low Hb, 24.7% (58 out of 234) had Hb between 12 and 12.4 g%. Similarly, among donor deferred for low platelet count, 12% (184 out of 1532) had platelet count between 140 and 149 × 103/μl. CONCLUSION There is potential for increasing the number of eligible plateletpheresis donors if the present donor selection criteria were relaxed to a minimum Hb of 12 g/dl and minimum platelet count of 140 × 103/μl.

Abstract
INTRODUCTION Algorithms have been developed to predict the platelet yield after apheresis from the donor's data, as well as the effect on the blood cell count, to extract an acceptable platelet number without affecting the donor. However, the evaluation of these algorithms has not been widely reported. This study aimed to assess the accuracy of the predictive algorithms of the Trima Accel v. 6 blood collection system. METHODS Platelet concentrates (PCs) obtained by apheresis were analyzed. Platelet count and hematocrit were compared pre- and post-apheresis. Calculated post-apheresis platelet count (CPAPC), hematocrit (CPAH), and platelet yield (CPY), and their actual values were correlated. The bias of the algorithms was assessed with Bland-Altman plots, and the prediction of the extraction of single or double platelet products was evaluated. RESULTS Two hundred and seventy-nine PCs were analyzed. Post-apheresis platelet count (PAPC) and hematocrit were decreased. A moderate correlation was observed between CPY and the actual yield, with a negative bias, and a trend to increase alongside the magnitude of the measurements. CPAPC and CPAH were strongly correlated with their actual values without bias. Prediction of single or double platelet product extraction showed a significant agreement with the actual outcomes. CONCLUSIONS The predictive algorithm for the platelet yield showed bias, and a trend to underestimate the actual platelet yields when they are higher. The algorithms for the prediction of the PAPC and hematocrit did not show bias, proving their accuracy. Prediction of a single or double platelet product extraction has a strong agreement with the APY.

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
With improvements in apheresis collection, platelet additive solution (PAS) is steadily replacing plasma as the storage medium in single donor platelets (SDP). Concentrating platelets in SDP with one-third of plasma and two-thirds of PAS is referred as Concentrated-SDP (C-SDP). We studied the influence of donor hematocrit (Hct) in C-SDP procedures. A retrospective study, consisting of 124 and 95 plateletpheresis donors in MCS+ and Trima respectively. We compared two apheresis equipments MCS+ and Trima with regard to donor hematocrit on procedural parameters such as collection efficiency (CE), collection rate (CR), yield per hour (Y/H), yield per litre (Y/L) and percentage blood volume processed (%BV) during C-SDP procedures. Donors were categorized into two groups with Group A (Hct ≤ 46%) and Group B (Hct > 46%) based on mean baseline Hct of the study population. Among the 219 procedures, the overall CE was significantly higher for Trima over MCS+ equipment (77 vs 56, P < 0.001). However, there was no difference in procedural outcomes like CE, Y/L, Y/H, CR with MCS+ or Trima equipment between groups. %BV processed had a negative correlation with hematocrit in MCS+ (r = - 0.305, P = 0.001) and no difference was observed with Trima equipment. Donor Hct influences C-SDP collection only in processed blood volume with MCS+ equipment. Trima had statistically better performance over MCS+ equipments in all procedural parameters during C-SDP procedures. The data will guide apheresis centre to choose equipments based on donor characteristics.

Abstract
Objective To recognize the profile of platelet donors and the profile of the plateletpheresis session as well as to investigate the main adverse events of platelet donation using plateletpheresis and associated risk factors. Methods This retrospective, cross-sectional and analytical study was performed with a quantitative approach by analyzing 316 donation files from February 2010 to December 2011. The IBM SPSS Statistics program was used for data processing and analysis. The chi-square test was used to verify whether there was an association between factors related to the procedure and the donor, and the adverse events that occurred. Results The mean age of platelet donors was 40 years old (standard deviation = 8.9), with the prevalent age group being between 40 and 49 years old; the prevalent blood type was O positive (53.8%), the mean duration of the procedure was 73 min and the mean amount of anticoagulant used was 360 mL. The association between procedure duration and the volume of anticoagulant was inverse and statistically significant; the longer the procedure and the greater the volume of anticoagulant used, the less adverse reactions occurred. Conclusion The low incidence of adverse events indicates that the procedure is well tolerated by donors. Obtaining data regarding the incidence of adverse events is a way of promoting a dynamic review of medical and nursing teams to improve the safety and comfort of the donor.

Abstract
As the use of single donor apheresis platelets and plateletpheresis procedures done steadily increases in India, the plateletpheresis donors are at an increased risk of postpheresis anemia and thrombocytopenia. This study was planned in order to evaluate the effect of plateletpheresis on the hematological parameters in the local donor population and to evaluate the possibility of following the 2day deferral for repeat plateletpheresis. A total of 60 plateletpheresis procedures performed over a period of 1year with CS 3000 Plus Baxter Fenwal were evaluated. All the post-donation hematological parameters showed a significant decrease from the pre-donation values (p<0.001). Post-donation hemoglobin <12g, which is defined by WHO as anemia irrespective of the gender occurred in 25% (n=15) of the donors. The post-donation platelet count was less than 100×10(9)/L in 16.6% (n=10) of the procedure. The ability of these donors to serve as repeat plateletpheresis donor after 2days as recommended by AABB needs to be evaluated by further studies done post donation. Keeping in view the hematological profile of our donor population we recommend that donors who already have a low or borderline pre-donation platelet count and hemoglobin should be assessed and monitored post-donation for decrements in these parameters. While serving as repeat donors, their pre donation hemoglobin and platelet counts should be tested again.

Abstract
BACKGROUND Although automated cell separators have undergone a lot of technical refinements, attention has been focused more on the quality of platelet concentrates than on donor safety. We planned this prospective study to observe the effects of automated plateletpheresis on normal haematological values of healthy donors and to determine whether the haematological alterations had any clinical consequences. STUDY DESIGN AND METHODS The study was conducted on 457 healthy, first-time plateletpheresis donors over a period of 26 months. The plateletpheresis procedures were performed using five different cell separators and various pre- and post-donation haematological values such as haemoglobin concentration (Hb), haematocrit (Hct), platelet and white blood cell (WBC) counts, mean platelet volume and platelet distribution width were measured in all donors. RESULTS We observed that the Hb, Hct, platelet and WBC counts decreased significantly in the donors (p<0.01) after each procedure, without there being significant changes in mean platelet volume or platelet distribution width. The decreases in Hb and Hct were significantly greater with the CS 3000 and Amicus machines, while the decreases in platelet and WBC counts were significantly greater with the CS 3000 and Fresenius separators. CONCLUSION Although a significant drop in complete blood count was observed in all donors, none manifested features of thrombocytopenia or anaemia. Nevertheless, more prospective studies on this aspect are required in order to establish guidelines for donor safety in apheresis and also to help in assessing donor suitability, especially given the present trend of double product apheresis collections.

Abstract
In a developing nation like India where there is a scarcity of resources and voluntary donors, provision of safe and good quality blood and its components is a huge challenge. The demand for platelets is increasing constantly due to better management of various patient categories, specifically hemato-oncological cases, where there is an increased demand of platelet transfusion. The use of apheresis single donor platelets (SDPs) has been attributed to increased gap between demand and supply of whole blood derived random donor platelets (RDPs). Moreover, the other benefits of SDPs such as decreased donor exposure and simplification of inventory management cannot be overlooked. However, the increased costs and logistic problems, compounded by the lack of awareness, limit the donor recruitment and procedures for SDPs. In Indian scenario, there are no specific guidelines or standards available which can be followed, while simultaneously addressing the associated problems. In this review, we have tried to analyze the various problems of donor selection, donor safety and the quality issues regarding plateletpheresis. Based on this we have tried to give certain recommendations which might help the centers in resolving the problems related to plateletpheresis.

Abstract
INTRODUCTION This study reports the frequency and nature of plateletpheresis deferrals and evaluates donors with low platelet count and hemoglobin levels so as to assess the possibility of reentry without hampering donor safety. MATERIALS AND METHODS Three-year retrospective data of plateletpheresis deferral was collected. Data from actual procedures was also reviewed to analyze the safety of performing plateletpheresis in donors with low hemoglobin and platelet values. RESULTS Four hundred sixteen donors were deferred for various reasons among 1,515 screened (27.5%), of which 69.7% deferrals were because of low platelet count (55.8%) and less hemoglobin levels. Among the low platelet count donor group, 20.3% had a count between 141 and 149 x 10(9)/L and 41.8% below 120 x 10(9)/L. Of the 14% donors deferred for low hemoglobin, 62.1% had values in the range of 11.5-12.4 g/dL with normal mean corpuscular volume and red cell distribution width in most (86.2%) of them. Expected blood loss in each procedure varied between 20 and 30 mL, whereas RBC contamination in the product varied from 0 to 1.6 mL in 538 procedures. There were 176 donations with predonation platelet count <180 x 10(9)/L (32.7%). None of the 14 procedures performed on donors with platelet count of 150 x 10(9)/L showed evidence of thrombocytopenia or donor reaction. CONCLUSION Lowering the cut-off value for plateletpheresis from 12.5 g/dL to 11.5 g/dL has no deleterious effect on donor safety as the blood loss is minimal. One-fifth deferrals can be reconsidered if the criteria of plateletpheresis donor selection are relaxed for hemoglobin and platelet count.

Abstract
The efficacy of the widely practiced 'Top and Bottom' collection system has been established. We studied efficacy of our new 'Top-and-Top' automated blood component separation system with regards to quality analysis of red cell and platelet concentrates. At installation of machine 59 U of whole blood (WB) were used for its calibration and validation program. Optimum volume, leukocyte-platelet recovery and red cells loss in BC were adjusted as per recommended standards. WB showed mean volume of 510 ml and net hemoglobin content of 63 g/bag. BC recovered 91.7% and 62.7% of platelet and leukocytes, respectively, in a mean volume of 96 ml a hematocrit of 54% and mean platelet of 5.47 x 10(10) were observed in red cell and platelet concentrates, respectively. In many aspects quality of our products could not comply with the recommended European and American standards and this requires a close insight into the series of activities associated with WB collection, separation and quality control program.
