Complement changes during leukapheresis

Transfusion, 1980
Alterations of the complement system occurring during continuous-flow filtration leukapheresis (CFFL) and intermittent-flow centrifugation leukapheresis (IFCL) were assessed in 16 donors. Five blood samples were obtained at timed intervals during each cytaphere-sis, three directly from each donor and two from the efferent lines returning blood from the

Evaluation of gravity leukapheresis and comparison with intermittent centrifugation leukapheresis

Transfusion, 1981
Fifteen normal donors underwent gravity leukapheresis using a prototype collection and reinfusion harness after receiving dexamethasone for leukocyte stimulation. A mean of 4.6 units of blood were processed, producing a mean granulocyte yield of 10.8 × 109, with an average donation time of 261 minutes.

Priapism During Filtration Leukapheresis

Transfusion, 1979
Priapism has been observed during two out of 3,680 filtration leukapheresis procedures in male donors and has been reported during hemodialysis. Both procedures are associated with enhanced granulocyte adhesion and aggregation presumably due to C5a. During both procedures, heparin is administered and this drug has been shown to cause heparin‐dependent ...

Comparison of Filtration Leukapheresis and Centrifugation Leukapheresis in Treatment of Lymphosarcoma Cell Leukemia

Southern Medical Journal, 1982
A patient with lymphosarcoma cell leukemia resistant to chemotherapy was treated with filtration leukapheresis and centrifugation leukapheresis. Filtration leukapheresis removed only 10(11) leukemia cells per 8.5 liters of blood processed, while centrifugation leukapheresis removed approximately six times as many leukemia cells from the same amount of ...

Microfluidic diffusive filter for apheresis (leukapheresis)

Lab Chip, 2006
Apheresis is a procedure used to fractionate whole blood into its individual components. Following fractionation, the desired component is isolated and the remaining blood in many cases is returned to the donor. Leukapheresis is one type of apheresis where leukocytes (white blood cells) are selectively removed. This procedure is commonly used for blood

The Hypereosinophilic Syndrome and Leukapheresis

Annals of Internal Medicine, 1979
Excerpt To the editor: Although the hypereosinophilic syndrome has been well reviewed recently (1, 2), leukapheresis was not considered as a therapeutic option in these reports.

Therapeutic leukapheresis and thrombapheresis in medical emergencies

Transfusion and Apheresis Science, 2020
The management of hyperleukocytosis or thrombocytosis by therapeutic cytapheresis in the early 21 st century is far from codified (universal). Therapeutic cytapheresis have been proposed to achieve more rapid cytoreduction in peripheral blood than old universal support in order to quickly prevent potential complications.

Leukapheresis in a Patient with Sézary Syndrome

Vox Sanguinis, 1984
Abstract. A patient with Sézary syndrome refractory to cytotoxic agents underwent leukapheresis on the Aminco continuous flow centrifuge. Five procedures were performed over a 15‐day period. A total of 6.9 × 109 cells were removed. The patient's skin lesions and lymphadenopathy regressed.Repeated removal of the buffy coat by leukapheresis has not ...

Granulocyte Kinetics in Donors Undergoing Filtration Leukapheresis

Transfusion, 1976
Normal blood donors undergoing filtration leukapheresis (FL) have a profound transient neutropenia early in the procedure which is followed by a “rebound” neutrophilia. This phenomenon occurs in unstimulated donors as well as in donors pretreated with either prednisone or dexamethasone.

Leukapheresis and pathogenetic mechanisms in rheumatoid arthritis

Journal of Clinical Apheresis, 1984
AbstractRheumatoid Arthritis is a chronic, usually progressive inflammatory disorder of joints in which the immune system plays a central role in the pathogenesis. In its classic form, the synovial tissues from severely affected joints are densely infiltrated with HLA‐DR bearing T‐lymphocytes (primarily OKT4+/Leu3+subset) and macrophage‐like cells ...
