Prevention of HLA immunization with leukocyte-poor packed red cells and platelet concentrates obtained by filtration.
HLA immunization is a common complication of transfusion therapy in 30% to 60% of oncohematologic patients. Evidence shows that leukocytes present in cellular blood products are the main component involved in the occurrence of HLA immunization, and several studies showed that leukocyte-poor blood products are less able to induce it. However, leukocyte-poor platelet concentrates obtained by conv...
متن کاملClinical experience with transfusion of leukocyte-poor platelet concentrates prepared by filtration with prostacyclin.
Repeated transfusions with platelets from randomly selected donors lead to HLA alloimmunization in about 50% of patients due to lymphocyte contamination of platelet concentrates. Attempts to remove the leukocytes from the platelet concentrates by additional centrifugation steps led to substantial loss of platelets. We report a new procedure for removal of almost all leukocytes with excellent pl...
متن کاملCorrection of poor platelet transfusion responses with leukocyte-poor HL-A-matched platelet concentrates.
Matching donor-recipient pairs for HL-A antigens provides a logical starting point for selecting donors for recipients with extensive prior transfusion histories. However, during the course of continued exposure to even HL-A-matched platelet concentrates, further sensitization occurs, as indicated by progressively poorer post-transfusion increments and transfusion reactions. There is evidence t...
متن کاملA Root Cause Analysis of Haemolysis Encountered in Leuco-filtration of Stored Packed Red Cells Units
Background and Aims: Leukoreduction of blood components has reduced the incidence of transfusion-associated adverse events. Leucofiltration is the most effective method of leukoreduction. We encountered haemolysis in a series of leucofiltered units. This stressed our precious inventory, added to financial loss, increased our turn-around time to issue leucofiltered blood units, and placed doubts...
متن کاملUse of leukocyte-depleted platelet concentrates for the prevention of refractoriness and primary HLA alloimmunization: a prospective, randomized trial.
Compared with conventional transfusion regimes a strong reduction in HLA alloimmunization and refractoriness to platelet transfusions is obtained when both red blood cell concentrates (RBCs) and platelet concentrates (PCs) are depleted of leukocytes by filtration. Because most of the leukocyte contamination is introduced by transfusion of RBCs, filtration of RBCs appears rational, but uncertain...
