The collection of autologous or allogeneic starting material for the expansion of NK cells - whether whole blood, cord blood, or leukocyte apheresis - requires the use of anticoagulants. Heparin and acid citrate dextrose A (ACD-A) are most commonly used for collection, but their impact on NK cells has not been clearly described. As functional impairment has been described for irreversible calcium chelation with EDTA, we hypothesized that prolonged calcium chelation by ACD-A might also have an adverse impact on NK cell health, particularly with prolonged exposure. To test this hypothesis, peripheral blood was collected as paired samples in heparin and in ACD-A, stored for 24 h at room temperature, and then tested for viable NK cell yield and proliferative capacity for 2 weeks under <em>ex vivo</em> expansion. Both conditions yielded similar viability and T/NK cell content after initial isolation. However, compared to ACD-A-treated blood, heparin-treated blood provided a mean 23 % higher initial yield of NK cells (p = 0.03) and a non-significant trend toward greater fold expansion, which resulted in 60 % higher overall yield after expansion (p = 0.048). These data suggest that both ACD-A and heparin can be used for NK cell collection, but that heparin may be the preferred anticoagulant if there is an expected delay in the product processing such as a pause for overnight testing or shipping. Process development for cellular therapeutics should assess the impact of anticoagulant used for cell collection.</div></div>","PeriodicalId":49422,"journal":{"name":"Transfusion and Apheresis Science","volume":"64 6","pages":"Article 104253"},"PeriodicalIF":1.2,"publicationDate":"2025-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145060922","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Deformability depends on the cell’s surface area-to-volume ratio, internal viscosity, and membrane elasticity. Deformability is assessed using single-cell methods like micropipette aspiration and bulk flow techniques such as ektacytometry. RBC deformability decreases during cold storage due to biochemical and structural changes known as storage lesions. Additional processes like cryopreservation and irradiation further impair the deformability of stored RBCs. Donor factors, including age, sex, lifestyle, and health, also influence RBC mechanical properties, affecting transfusion outcomes. Clinically, transfusing RBCs with reduced deformability is linked to impaired microvascular flow, decreased oxygen delivery, and faster clearance from the circulation, especially in patients with chronic or inflammatory conditions. Despite its importance, deformability testing is not yet standard in transfusion practice.

Rather than treating these surplus units as waste, blood establishments can repurpose them into safe, useful biotherapies. This updated perspective article highlights practical approaches to valorize surplus blood and plasma through preparation of pathogen-reduced cryoprecipitate and cryoprecipitate-reduced plasma; serum eye drops; mini-pool immunoglobulins; and contract fractionation to produce plasma derived medicinal products (PDMPs, e.g., immunoglobulins, clotting factors, and albumin), complemented, where feasible, by commercially sourced PDMPs or alternative recombinant products. Concurrent plasma from plateletpheresis provides an additional underutilized source of plasma potentially suitable for fractionation. Similarly, expired platelet concentrates can be converted into human platelet lysates, growth-factor concentrates, or extracellular vesicles for cell therapy applications and advanced regenerative medicine. Implementation of these developments requires strict alignment with international quality standards, appropriate microbial and viral safety measures, and clear regulatory oversight. Importantly, the clinical use of allogeneic blood products, especially emerging platelet-derived preparations, should be reserved for justified and proven indications. Repurposing surplus plasma and platelets is not only a way to reduce waste, but also an opportunity for blood establishments to play a driving role in the delivery of safe, evidence-based biotherapies that augment and expand treatment options, improve patient outcomes, and foster national strategic independence, sustainability and resilience in access to current and emerging biotherapies.</div></div>","PeriodicalId":49422,"journal":{"name":"Transfusion and Apheresis Science","volume":"64 6","pages":"Article 104277"},"PeriodicalIF":1.2,"publicationDate":"2025-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145356578","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We conducted a retrospective, single-center study of 45 acute liver failure patients who received HVP at the Poison Control Center, Bach Mai Hospital, Hanoi, Vietnam, to describe the 28-day outcomes, treatment-related complications, and factors associated with survival. Patient variables including age, gender, etiology, survival at 28 days, international normalized ratio (INR), plasma volume per exchange, hospital stay, and complications were collected. Data were analyzed using SPSS 27. Descriptive statistics (mean ± SD, median ± IQR) were applied, and INR was compared between survivors and non-survivors using t-test (p < 0.05). The mean age was 47 ± 16 years; 24 (53.3 %) were male. Leading etiologies were traditional medicine/herbal use 22(48.9 %), paracetamol 9(20.0 %), and other causes 14(31.1 %). The 28-day survival rate was 53.3 % (24/45). Mean INR at admission was 3.30 ± 2.45; survivors had lower INR (2.67) than non-survivors (4.02), though not statistically significant (p = 0.082). Each HVP used a mean plasma volume of 8.27 ± 1.19 L. Mean hospital stay was 9.8 ± 7.3 days.

In this cohort, HVP (mean 8.27 L per exchange) was associated with a 28-day survival rate of 53.3 %, comparable to that reported in previous studies, though causality cannot be inferred due to the absence of a control group.
