Tran LNT, González-Fernández C, Gomez-Pastora J. Impact of Different Red Blood Cell Storage Solutions and Conditions on Cell Function and Viability: A Systematic Review. Biomolecules 2024; 14:813. [PMID: 39062526 PMCID: PMC11274915 DOI: 10.3390/biom14070813] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/25/2024] [Revised: 07/01/2024] [Accepted: 07/05/2024] [Indexed: 07/28/2024] Open
Abstract
Red blood cell (RBC) storage solutions have evolved significantly over the past decades to optimize the preservation of cell viability and functionality during hypothermic storage. This comprehensive review provides an in-depth analysis of the effects of various storage solutions and conditions on critical RBC parameters during refrigerated preservation. A wide range of solutions, from basic formulations such as phosphate-buffered saline (PBS), to advanced additive solutions (ASs), like AS-7 and phosphate, adenine, glucose, guanosine, saline, and mannitol (PAGGSM), are systematically compared in terms of their ability to maintain key indicators of RBC integrity, including adenosine triphosphate (ATP) levels, morphology, and hemolysis. Optimal RBC storage requires a delicate balance of pH buffering, metabolic support, oxidative damage prevention, and osmotic regulation. While the latest alkaline solutions enable up to 8 weeks of storage, some degree of metabolic and morphological deterioration remains inevitable. The impacts of critical storage conditions, such as the holding temperature, oxygenation, anticoagulants, irradiation, and processing methods, on the accumulation of storage lesions are also thoroughly investigated. Personalized RBC storage solutions, tailored to individual donor characteristics, represent a promising avenue for minimizing storage lesions and enhancing transfusion outcomes. Further research integrating omics profiling with customized preservation media is necessary to maximize post-transfusion RBC survival and functions. The continued optimization of RBC storage practices will not only enhance transfusion efficacy but also enable blood banking to better meet evolving clinical needs.

Deviations in red cell blood component temperature during laboratory processing and at blood return monitored by a time-temperature indicator device. Transfus Med 2022; 32:484-491. [PMID: 36239101 DOI: 10.1111/tme.12924] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/07/2022] [Revised: 09/13/2022] [Accepted: 09/29/2022] [Indexed: 11/28/2022]
Abstract
OBJECTIVES To evaluate the performance and utility of a time-temperature indicator (TTI) to determine the cumulative exposure time (CET) of red cell components (RCC) to temperatures above 10°C occurring within and outside the transfusion laboratory. BACKGROUND AND OBJECTIVES Blood centres often use the '30 or 60-min rule' for accepting RCC exposed to room temperature (RT) back into inventory. Effective monitoring of these temperature deviations is however lacking. MATERIALS AND METHODS A Timestrip PLUS® TP153 10°C (TS + 10) TTI was attached to RCC units after preparation of the unit in the blood bank or on issue to the ward, to track the CET > 10°C during laboratory processing and outside the transfusion laboratory. RESULTS The mean CET of 153 RCC tracked within the laboratory was 56 min. Sixty-four (41.8%) and 34 (22.2%) of RCC had core temperature (CT) >10°C for more than 30 and 60 min, respectively. Among the 69 RCC that were returned unused, 27 (39.1%), 17 (24.6%) and 5 (7.2%) RCC units had CT >10°C for more than 30, 60 and 120 min respectively. CONCLUSION A large proportion of RCC have CT >10°C exceeding 30 min during handling within the transfusion laboratory, as well as when RCC are returned unused from transfusion locations. Corrective measures should be implemented to better manage the cold chain to avoid undesirable consequences to blood transfusion. A temperature sensitive device that can also indicate CET can be employed to objectively monitor the period that RCC remained at a CT that exceeds 10°C.

Abstract
BACKGROUND AND OBJECTIVES Red blood cell concentrates (RBCC) are susceptible to bacterial contamination despite cold storage. A reliable evaluation of strategies to minimize the risk of RBCC-associated bacterial transmission requires the use of suitable reference bacteria. Already existing Transfusion-Relevant Bacteria Reference Strains (TRBRS) for platelet concentrates fail to grow in RBCC. Consequently, the ISBT TTID, Working Party, Bacterial Subgroup, conducted an international study on TRBRS for RBCC. MATERIALS AND METHODS Six bacterial strains (Listeria monocytogenes PEI-A-199, Serratia liquefaciens PEI-A-184, Serratia marcescens PEI-B-P-56, Pseudomonas fluorescens PEI-B-P-77, Yersinia enterocolitica PEI-A-105, Yersinia enterocolitica PEI-A-176) were distributed to 15 laboratories worldwide for enumeration, identification, and determination of growth kinetics in RBCC at days 7, 14, 21, 28, 35 and 42 of storage after low-count spiking (10-25 CFU/RBCC). RESULTS Bacterial proliferation in RBCC was obtained for most strains, except for S. marcescens, which grew only at 4 of 15 laboratories. S. liquefaciens, S. marcescens, P. fluorescens and the two Y. enterocolitica strains reached the stationary phase between days 14 and 21 of RBCC storage with a bacterial concentration of approximately 109 CFU/ml. L. monocytogenes displayed slower growth kinetics reaching 106 -107 CFU/ml after 42 days. CONCLUSION The results illustrate the importance of conducting comprehensive studies to establish well-characterized reference strains, which can be a tool to assess strategies and methods used to ameliorate blood safety. The WHO Expert Committee on Biological Standardization adopted the five successful strains as official RBCC reference strains. Our study also highlights the relevance of visual inspection to interdict contaminated RBC units.

Fatty Acid Reference Intervals in Red Blood Cells among Pregnant Women in Norway-Cross Sectional Data from the 'Little in Norway' Cohort. Nutrients 2020; 12:nu12102950. [PMID: 32993043 PMCID: PMC7601079 DOI: 10.3390/nu12102950] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/27/2020] [Revised: 09/23/2020] [Accepted: 09/24/2020] [Indexed: 12/15/2022] Open
Abstract
There is a growing interest in determining fatty acid reference intervals from pregnancy cohort, especially considering the lack of reference values for pregnant women in the literature and the generalized misconception of equating reference intervals for nonpregnant women as equivalent to pregnant women. Seafood and supplements are important dietary sources for the omega-3 long-chain polyunsaturated fatty acids (ω-3 LCPUFA), such as eicosapentaenoic acid (EPA, 20:5ω-3), docosapentaenoic acid (DPA, 22:55ω-3), and docosahexaenoic acid (DHA, 22:6ω-3). Sufficient intake of EPA and DHA is vital during pregnancy for the development of the fetus, as well as for maintaining adequate levels for the mother. This study describes the fatty acid status and suggests reference values and cut-offs for fatty acids in red blood cells (RBC) from pregnant women (n = 247). An electronic food frequency questionnaire (e-FFQ) mapped the dietary habits of the participants, and gas chromatography was used to determine the fatty acid levels in RBC. The association between e-FFQ variables and fatty acid concentrations was established using a principal component analysis (PCA). Twenty-nine-point-one percent (29.1%) of the participants reported eating seafood as dinner according to the Norwegian recommendations, and they added in their diet as well a high percentage (76.9%) intake of ω-3 supplements. The concentration levels of fatty acids in RBC were in agreement with those reported in similar populations from different countries. The reference interval 2.5/97.5 percentiles for EPA, DPA, DHA were 0.23/2.12, 0.56/2.80, 3.76/10.12 in relative concentration units (%), and 5.99/51.25, 11.08/61.97, 64.25/218.08 in absolute concentration units (µg/g), respectively. The number of participants and their selection from all over Norway vouch for the representativeness of the study and the validity of the proposed reference values, and therefore, the study may be a useful tool when studying associations between fatty acid status and health outcome in future studies. To the best of our knowledge, this is the first PCA study reporting a direct association between ω-3 LCPUFA and intake of seafood and ω-3 supplements in a pregnancy cohort.

Transfus Apher Sci 2020; 59:102908.

Abstract
INTRODUCTION Temperature and time conditions during storage and distribution of blood components (BC) and their permissible deviations are strictly regulated. The degree of compliance with these requirements in daily practice of transfusion services (TS) is not well known. MATERIALS AND METHODS We conducted a survey among Spanish hospital TS covering different aspects of BC management in their daily activity. RESULTS Eighty-three TS managing 56 % of total transfusions answered the survey. Monitoring of red blood concentrates (RBC) temperature during in-hospital distribution was routinely performed by only 12 % of the TS. The main criterion for BC re-entry into the stock was the total time spent outside controlled temperature. Up to 41 % of the TS apply the "30-minute rule" to distributed RBC, while most services use a 60-minute rule for PC. No adverse events were detected when RBC that had remained longer than 30 or 60 min outside the TS were transfused. Fresh frozen plasma is usually thawed 2 h preissue and stored at 4 °C up to 24 h. DISCUSSION AND CONCLUSIONS In the Spanish context, the 30- and 60-minute rules for re-entry of RBC and PC into the TS stock are loosely followed. Feedback for a large number of TS suggests that the extension of the 30-minute RBC rule to at least 60 min is feasible, if other safety requirements are met. Flexibility with some requirements could help reduce product loss without deleterious effect on BC safety.

Abstract
BACKGROUND AABB requires that red blood cells (RBCs) are maintained at 1 to 10°C during transport. Historically, blood banks used the 30-minute rule for returned RBCs transported outside of validated containers. The implications of this policy have not been previously reported in a real-life hospital setting. STUDY DESIGN AND METHODS A 2-year, retrospective review of RBC units returned outside of qualified containers was conducted. During the first year, the 30-minute rule was used to accept RBCs back into inventory. Sequentially, the following year, a temperature-based approach was implemented using a thermometer with an accuracy of ±1°C. Time out of the blood bank, temperature upon return, wastage, and transfusion reactions associated with the reissued RBCs were analyzed. RESULTS In our practice, the 30-minute rule would have accepted 15.2% of RBC units outside of the allowed temperature. Compared to the 30-minute rule, temperature-based acceptance was associated with a 13% increase in wastage (p < 0.001). During the 30-minute rule period, transfusion of returned and subsequently reissued RBCs was associated with a nonsignificant trend toward a higher transfusion reaction rate compared to the overall RBC transfusion reaction rate (1.4% vs. 0.6%, p = 0.084). During the temperature period, transfusion of returned and subsequently reissued RBCs had the same transfusion reaction rate compared to the overall RBC transfusion reaction rate (0.5% vs. 0.5%, p = 1.0). CONCLUSION Temperature-based acceptance of returned RBCs is associated with significantly higher wastage compared to the 30-minute rule. A temperature-based acceptance practice mitigates the risk of accepting RBCs with unacceptable temperatures returned within 30 minutes of issue.

Abstract
BACKGROUND To maintain product quality and safety, the '30-min rule' requires the discard of red blood cells (RBCs) that are exposed to uncontrolled temperatures for more than 30 min. Recent studies suggest this rule may safely be extended to a 60-min rule. METHODS A pool-and-split design study (N = 4) was run in parallel at Canadian Blood Services (SAGM RBCs) and Héma-Québec (AS-3 RBCs). RBCs were spiked with ∼1 colony-forming unit/ml of mesophilic and psychrophilic bacteria. Control units remained in storage at 1-6 °C for 42 days. Test 30 (T30) and T60 units were exposed to room temperature (RT) six times during storage, each time for 30 and 60 min, respectively. Bacterial proliferation was monitored. RESULTS Mesophilic bacteria do not proliferate in RBCs. The growth of psychrophilic bacteria is not significantly different in RBCs exposed for 30 or 60 min to RT (p < 0.05). CONCLUSION The study findings were the final evidence to support extension from a 30-min rule to a 60-min rule in Canada.
