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
OBJECTIVES Whole blood-derived platelet concentrates can be obtained by the platelet-rich plasma (PRP-PCs) or the buffy-coat (BC-PCs) method. Few studies have shown that BC-PCs display lower in vitro platelet activation, but scarce information exists regarding transfusion efficacy. We have performed a retrospective study assessing platelet transfusion in patients undergoing allogeneic hematopoietic cell transplantation (AHCT) in our clinic, before and after the implementation of BC-PCs. METHODS We reviewed clinical records corresponding to 70 PRP-PCs and 86 BC-PCs prophylactic transfusions, which were performed to 55 AHCT patients. Transfusion efficacy was assessed by the 24-h post-transfusion corrected count increment (24-h CCI) and bleeding events. Clinical factors affecting transfusion outcome were also investigated. RESULTS Clinical characteristics and the total number of platelet transfusions were similar among groups. Mean donor exposure was 5.8 and 5.0 in each single PRP-PCs and BC-PCs transfusion, respectively (p < 0.01). The 24-h CCI was significantly higher in patients transfused with BC-PCs than in those receiving PRP-PCs (8.3[2.7-13.4] vs. 4.7[1.3-8.1]; p < 0.01). Independent predictors of poor platelet transfusion response included diagnosis other than acute leukemia (HR 8.30; 95% CI 1.96-35.22; p = 0.004), splenomegaly (HR 8.75; 95% CI 2.77-27.60; p < 0.001), graft versus host disease prophylaxis different from cyclosporine A and methotrexate (HR 3.96; 95% CI 1.55-10.14; p = 0.004) and PRP-PCs transfusion (HR 4.54; 95% CI 1.72-12.01; p = 0.002). There were no differences between both groups regarding the bleeding events. CONCLUSION In the AHCT setting, we hypothesize that BC-PCs transfusion, when compared to PRP-PCs, results in higher CCI and reduced donor exposure, but provides no significant benefit regarding bleeding outcome.
