Abstract
If technological innovations are not enough alone to improve blood safety, their contributions for several decades in blood transfusion are major. The improvement of blood donation (new apheresis devices, RFID) or blood components (additive solutions, pathogen reduction technology, automated processing of platelets concentrates) or manufacturing process of these products (by automated processing of whole blood), all these steps where technological innovations were implemented, lead us to better traceability, more efficient processes, quality improvement of blood products and therefore increased blood safety for blood donors and patients. If we are on the threshold of a great change with the progress of pathogen reduction technology (for whole blood and red blood cells), we hope to see production of ex vivo red blood cells or platelets who are real and who open new conceptual paths on blood safety.

Johnson L, Kwok M, Marks DC. Preparation of red blood cell concentrates and plasma units from whole blood held overnight using a hollow-fibre separation system. Transfus Med 2015; 25:13-9. [PMID: 25808374 DOI: 10.1111/tme.12192] [Citation(s) in RCA: 8] [Impact Index Per Article: 0.9] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/30/2014] [Revised: 02/22/2015] [Accepted: 03/10/2015] [Indexed: 11/28/2022]
Abstract
BACKGROUND The ErySep system represents an alternative to centrifuge-based whole blood (WB) separation, using gravity and filtration through hollow-fibres (0·2 µm pore size) to produce red blood cell (RBC) and plasma components. The aim of this study was to characterise the quality of ErySep RBC and plasma units compared with standard products from WB held overnight. METHODS/MATERIALS Two ABO-compatible WB units (n = 24) were pooled and split to produce matched products. One of the WB units was separated into components using the ErySep system (ErySep; n = 12), whereas the other units were separated by centrifugation (control; n = 12). RBC units were stored at 2-6 °C and assessed for in vitro quality over 42 days of storage. Plasma was frozen at -30 °C and tested upon thawing. RESULTS Processing WB with the ErySep system took longer than controls. The ErySep RBC units were of an appropriate volume (307 ± 17 mL) and contained sufficient Hb (50 ± 2 g unit(-1) ). ErySep RBC components contained more microparticles relative to controls at expiry. The plasma volume, total protein, coagulation factor activity (fibrinogen, FV, FVIII) and number of microparticles was lower in the ErySep units compared with controls. CONCLUSION Following overnight hold of WB, the ErySep system was capable of producing RBC components that met specifications. However, the ErySep plasma components did not meet quality specifications.

Vox Sang 2014; 107:261-8. [PMID: 24861237 DOI: 10.1111/vox.12159] [Citation(s) in RCA: 6] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/17/2013] [Revised: 04/24/2014] [Accepted: 04/25/2014] [Indexed: 11/30/2022]
Abstract
BACKGROUND AND OBJECTIVES TACSI whole blood system is designed to combine primary and secondary processing of six whole blood bags into plasma units, buffy coat and red blood cell concentrates. The aim of this study was to investigate the specifications and in vitro storage parameters of blood components compared with standard centrifugation and separation processing. MATERIALS AND METHODS Whole blood bags, collected in CRC kits, were treated on a TACSI whole blood system. They were compared with whole blood bags collected in Composelect kits. In addition to routine quality control analyses, conservation studies were performed on red blood cell concentrates for 42 days and on plasma for 6 months. Platelets pools with five buffy coats were also created, and cellular contamination was evaluated. RESULTS Red blood cell concentrates produced from TACSI whole blood met European quality requirements. For white blood cell count, one individual result exceeded 1 × 10(6) cells/unit. All plasma units fell within specifications for residual cellular contamination and storage parameters. The performances of the TACSI whole blood system allow for the preparation of low volume buffy coats with a recovery of 90% of whole blood platelets. Haemoglobin losses in TACSI BC are smaller, but this did not result in higher haemoglobin content of red cells. These BC are suitable for the production of platelet concentrates. CONCLUSION From these in vitro data, red blood cell concentrates produced using TACSI whole blood are suitable for clinical use with a quality at least equivalent to the control group.

Abstract
BACKGROUND AND OBJECTIVES Semi-automatic separation devices can be used for the separation of centrifuged whole blood into leucoreduced red cell concentrate (LR-RCC), plasma and buffy coat (BC) and to make platelet concentrates (PC) from pooled BCs. To improve and to obtain a more uniform and standardized process, the CompoMat G5 (Fresenius) was implemented, a new-generation semi-automated device. MATERIALS AND METHODS Uniform programs for WB separation and preparation of PCs were validated, using collection and pooling systems with CompoFlow (CF) closures, which can be automatically opened by the G5. Cell counts were performed and compared with historic data of blood components obtained with the formerly used Compomat G4 and Optipress II. After implementation, different adjustments were made to improve product quality. RESULTS Leucoreduced red cell concentrates (280 ± 15 ml, 53 ± 5 g haemoglobin) and plasma (317 ± 16 ml) met European guidelines. BCs (48 ± 2 ml, 0·42 ± 0·05 l/l, 93 ± 25 × 10(9) platelets) contained a similar platelet (PLT) content as BC prepared before with the Compomat G4. A relatively high percentage (4-6%) of PCs (330 ± 17 ml, 330 ± 50 × 10(9) PLT, 0·12 ± 0·21 × 10(6) leucocytes) contained <250 × 10(9) PLT which was the subject of improvement studies. After implementation, RCC and BC discard decreased and workload was less. Operator complaints were also less frequent. CONCLUSION The same high-quality blood components can be prepared by using the CompoMat G5 as previously with other semi-automated devices. Improvement was realized by automation of the opening process by the use of collection systems with CF closures, which led to a decrease in discarded units and workload.

Abstract
BACKGROUND The Atreus system (Terumo BCT) automates the preparation of blood components from whole blood donations. Intermediate platelet (PLT) products can be pooled manually or with the OrbiSac (Terumo BCT) and suspended in different PLT additive solutions (PASs) to obtain PLT concentrates (PCs). The aim of our study was to compare the in vitro PLT quality of PCs obtained with either the Atreus 2C+ and the OrbiSac or the Atreus 3C and suspended in PAS-II or PAS-IIIM during storage for up to 7 days. STUDY DESIGN AND METHODS We prepared eight PCs from buffy coats obtained with Atreus 2C+, pooled with the OrbiSac, and suspended in PAS-II and eight PCs from interim PLT units obtained with the Atreus 3C and suspended either in PAS-II or in PAS-IIIM. We measured volume, PLT content, and mean PLT component and performed metabolic assays (pH, glucose, lactate, pO₂, and pCO₂) and flow cytometry analyses (GPIb, GPIIbIIIa, GPIV, CD62P, CD63, von Willebrand factor [vWF], fibrinogen, Factor V, and annexin V). RESULTS PCs prepared with the Atreus 3C showed lower volume and higher PLT concentration when compared with PCs prepared with the Atreus 2C+ and the OrbiSac (p < 0.05). Glucose consumption rate and the expression of CD62P, CD63, and vWF were lower in PCs suspended in PAS-IIIM when compared with PCs suspended in PAS-II (p < 0.05). CONCLUSION PCs prepared with the Atreus 3C and suspended in PAS-IIIM preserve satisfactorily the in vitro PLT quality during 7-day storage. PLT activation during a 7-day storage period was lower when the storage solution was PAS-IIIM in comparison with PAS-II.

Abstract
BACKGROUND The Food and Drug Administration (FDA) requires that red blood cells must be refrigerated within 8 hours of whole blood collection. Longer storage of whole blood at 22°C before component preparation would have many advantages. STUDY DESIGN AND METHODS Two methods of holding whole blood for 20 to 24 hours at room temperature were evaluated, refrigerated plates or a 23°C incubator. After extended whole blood storage, platelet (PLT) concentrates were prepared from PLT-rich plasma on Day 1 postdonation, and the PLTs were stored for 6 more days. On Day 7 of PLT storage, blood was drawn from each subject to prepare fresh PLTs. The stored and fresh PLTs were radiolabeled and transfused into their donor. RESULTS Eleven subjects' whole blood was stored using refrigerated butanediol plates (Compocool, Fresenius), and 10 using an incubator. Poststorage PLT recoveries averaged 47 ± 13% versus 53 ± 11% and survivals averaged 4.6 ± 1.7 days versus 4.7 ± 0.9 days for Compocool versus incubator storage, respectively (p = NS). With all results, poststorage PLT recoveries averaged 75 ± 10% of fresh and survivals 57 ± 13% of fresh; PLT recoveries met FDA guidelines for poststorage PLT viability but not survivals. CONCLUSION Seven-day poststorage PLT viability is comparable when whole blood is stored for 22 ± 2 hours at 22°C using either refrigerated plates or an incubator to maintain temperature before preparing PLT concentrates.

Abstract
Labile blood products are obtained from samples of whole blood or aphaeresis. The techniques of preparation evolve with technological advances, which allow both an increasing automation and an intensification of the sanitary safety of the blood products. Over the last ten years, thanks to the availability of new technologies, several measures have been introduced in order to reduce the risk of transmission of pathogens and prevent the onset of transfusion-related acute lung injury (TRALI): leukoreduction, use of platelet storage solutions, inactivation of plasma and presumably of platelets in a very near future. The control of transfusion risk also depends on proper use of labile blood products. To assist the prescriber in his treatment options and to standardize practices, the French Agency for Sanitary Safety of Health Products has issued recommendations in terms of utilization of blood products that are detailed in this review of major labile blood products available.

Abstract
Blood services routinely separate whole blood into components that are then stored under different conditions. The storage conditions used for whole blood prior to separation must therefore be a compromise between the needs of the red cells (which benefit from refrigeration) and plasma and platelets (which are better preserved at ambient temperature). For many years, the approach has been to manufacture plasma and platelet components on the day of blood collection, and to refrigerate any unprocessed blood for manufacture into red cell components on the following day. However, this can make it challenging to maintain adequate stocks of all components. The European practice of 'ambient hold' of whole blood for up to 24 hours prior to processing allows greater flexibility in blood component manufacture, and the data reviewed suggest there is relatively little impact on the quality of red cell or plasma components, and an improvement in the quality of platelet components.

Abstract
The preparation of labile blood products in a blood bank is in permanent technological progress. Many operations, such as blood centrifugation, components separation, etc. are now performed by automated devices. A new generation of equipments is able to prepare blood products by reducing the number of manual operations. Therefore, buffy-coat platelet concentrate preparation and whole blood preparation can be prepared by these automated systems. Consequently, this directly impacts working conditions of employees, quality of blood products and process management.
