Damage of granulocytes in filtration leukapheresis (FL).

چکیده
To The Editor: To elucidate the mechanism of granulocyte damage during FL, studies have been reported of the interaction between nylon-wool fibers and isolated granulocytes suspended in protein free media,’2 in 5% plasma,2 or in 1% human serum albumin.3 In FL, however, heparinized whole blood is passed through a nylon-wool filter, resulting in plasma protein coating of the fibers within seconds.4 Cell adhesion to a plasma-protein-coated surface is a biologically active process that is fundamentally different from the passive and very firm attachment of cells to a naked, synthetic surface.56 Consequently, the interaction of nylon fibers and granulocytes in a protein-free medium is not a relevant model for granulocyte-fiber interaction during FL. In the presence of undiluted plasma, we observed no passive adhesion of granulocytes to glass, whereas 10% plasma and 1% human serum albumin reduced, but did not by far

In vitro function and post-transfusion survival of granulocytes collected by continuous-flow centrifugation and by filtration leukapheresis.
The function of granulocytes collected by continuous-flow centrifugation (CFC) and by filtration leukapheresis (FL) was studied in vitro, and the post-transfusion recovery and intravascular survival of these cells was studied by autologous transfusion in normal donors. Granulocytes collected by both FL and CFC leukapheresis (CFCL) functioned normally in the quantitative nitroblue tetrazolium, o...

Although granulocyte transfusion therapy has been shown to be effective in infected granulocytopenic animals and humans, the relative effectiveness of granulocytes (PMN) harvested by continuous flow centrifugation (CFC) or by continuous flow filtration leukapheresis (FL) remains uncertain. Studies in vitro of morphology and granulocyte functions have suggested cells collected by FL may be damag...
متن کاملEffects of temperature on granulocyte preservation.
With the increasing use of granulocyte transfusion it is becoming important to determine if granulocytes can be preserved for a few days. If so, the optimum storage conditions must be identified. We studied the function in vitro of granulocytes collected as they would be for transfusion by continuous-flow centrifuge leukapheresis (CFCL) and filtration leukapheresis (FL). Granulocytes collected ...
متن کاملReversal of granulocyte adherence to nylon fibers using local anesthetic agents: possible application to filtration leukapheresis.
The effects of the cationic anesthetic agents tetracaine and lidocaine on granulocyte function, morphology, and adherence to nylon fibers were studied in an attempt to improve current methods of granulocyte collection by filtration leukapheresis (FL). When dissolved in acid-citrate-dextrose (ACD) plasma, these drugs significantly increased granulocyte elution from the fibers in a dose-related f...
