In resource-constrained settings, buffy coat-derived granulocyte pools may serve as a feasible alternative.</div></div><div><h3>Aims</h3><div>To assess the feasibility of pooling buffy coat (BC) derived granulocytes, validate the pooling process, and compare granulocyte yield between two different pooling strategies (pool of 4 vs. pool of 6 BC)</div></div><div><h3>Materials and Methods</h3><div>A prospective study was conducted using buffy coats from routine 450 mL whole blood donations (N = 150). BCs were pooled (N = 60 for pool of 4 vs N = 90 for pool of 6 BC-GCs). Donor, individual buffy coat, pooled buffy coat samples were analyzed for volume, complete blood counts, platelet and granulocyte yield.

All 6-BC pools met the EDQM granulocyte dose threshold (>5 × 10⁹/unit), whereas only 33 % of 4-BC pools did. Sterility was maintained throughout. To reduce red cell content for pediatric suitability, 6 RBC-reduced pools underwent high-speed centrifugation. Compared to the unmanipulated pools, RBC-reduced pools demonstrated significantly lower volume and RBC volume and significantly higher granulocyte concentration (42.8 ± 16.1 vs. 24.0 ± 3.1 ×10 ³/µL, p = 0.035) with preserved total granulocyte yield (p = 0.40). However, a key limitation of our study is the lack of functional assays to assess post-processing granulocyte viability and phagocytic activity.</div></div><div><h3>Conclusion</h3><div>This approach offers a cost-effective, logistically simpler method for generating granulocyte-rich components where apheresis is not feasible. Pooled buffy coat granulocytes can be a viable alternative in settings with limited access to granulocytapheresis, meeting acceptable quality standards for clinical use.</div></div>","PeriodicalId":49422,"journal":{"name":"Transfusion and Apheresis Science","volume":"65 1","pages":"Article 104373"},"PeriodicalIF":1.2,"publicationDate":"2026-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145924951","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}

By removing circulating pathogenic substances such as autoantibodies, immune complexes, complement components, and pro-inflammatory cytokines, TPE rapidly interrupts humoral pathways driving tissue injury. This review summarizes the mechanisms through which plasma exchange modulates immune activity, including both depletion of harmful plasma factors and restoration of normal homeostatic proteins when donor plasma is used. Biomarker analyses demonstrate predictable reductions in immunoglobulins, cytokines, and complement activity, reflecting the profound but transient immune reset achieved with TPE. Comparisons with related apheresis modalities, such as immunoadsorption, double filtration plasmapheresis, and extracorporeal photopheresis, highlight the unique advantages of TPE as a broadspectrum immunomodulatory intervention. Clinically, TPE remains a vital therapeutic option in conditions ranging from thrombotic thrombocytopenic purpura and myasthenia gravis to vasculitis and cytokine storm syndromes. As evidence and technology evolve, plasma exchange continues to exemplify how biophysical removal of pathogenic plasma constituents can effectively restore immune balance and improve patient outcomes in both acute and chronic immune-mediated diseases.</div></div>","PeriodicalId":49422,"journal":{"name":"Transfusion and Apheresis Science","volume":"65 1","pages":"Article 104371"},"PeriodicalIF":1.2,"publicationDate":"2026-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145913572","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}
