The effects of large-volume leukapheresis on hemoglobin, platelet and coagulation in patients with hyperleukocytic leukemia.

Introduction: This study retrospectively analyzed a total of 86 leukapheresis treatments in 55 patients with hyperleukocytic leukemia (HLL).

Methods: In the leukapheresis treatments, the monitoring collection (MNC) program in COBE spectra continuous flow centrifuge (CFC) for blood component separator was used.

Results: In this study, the white blood cell (WBC) suspension volume collected in leukapheresis treatment were 870.72±208.40 mL, and significantly larger than that reported in previous study. Compared with before leukapheresis, there were no difference in patient with HLL on the peripheral blood platelet (PLT) count and hemoglobin (HGB) levels. The index plasma fibrinogen (FIB) concentration was slightly reduced by leukapheresis, however, it did not affect a lot the maintenance of normal hemostatic function in patients with HLL.

Discussion: Our data provided evidences that large-volume leukapheresis had no obvious effects on HGB level and coagulation functions in patient with HLL. So large-volume leukapheresis by CFC could be widely used in clinic.
