Cross-Regional Supply of Washed Apheresis Platelets through Hospital-Blood Center Collaboration: A Case Experience

A 64-year-old male patient diagnosed with B-cell lymphoma required regular platelet transfusions due to persistent thrombocytopenia.Over time, he developed severe transfusion-related allergic reactions, including anaphylaxis, necessitating the use of washed apheresis platelets (W-APLT).However, as the designated blood center was unable to produce W-APLT, the issue was resolved by collaborating with a neighboring blood center to source the product.Key strategies included verifying the patient's history of transfusion-related anaphylaxis, coordinating the production schedule of blood products, and implementing administrative procedures such as pre-scheduled ambulance transport on the day of transfusion.These measures ensured the timely supply of W-APLT while minimizing the risk of product wastage.As a result, the patient successfully received multiple W-APLT transfusions without further allergic reactions.This case serves as a model for overcoming infrastructure limitations in W-APLT supply through hospital-blood center collaboration, to provide timely and safe blood products to patients at risk of severe transfusion-related allergic reactions and anaphylaxis.(
