Effect of High-Volume Leukapheresis on Hematological Indexes of Patients with Hyperleukocytic Leukemia
OBJECTIVE: To improve the collection efficiency of leukapheresis, explore relatively scientific and objective evaluation indicators for collection effect, and observe the effect of high-volume leukapheresis on blood cells and coagulation function.
METHODS: A total of 158 times of high-volume leukapheresis were performed on 93 patients with hyperleukocytic leukemia by using continuous flow centrifugal blood component separator. 1/5-1/4 of total blood volume of the patients was taken as the target value of leukocyte suspension for single treatment. In addition, the total number of white blood cells (WBCs) subtracted, value of WBCs reduction, rate of WBCs reduction, decrease value of WBCs count, decrease rate of WBCs count, amount of hemoglobin (Hb) lost, value of Hb lost, decreased value of Hb, total number of platelet (PLT) lost, the value of PLT loss, and decrease value of PLT count were used to comprehensively evaluate the collection effect of leukapheresis and influence on Hb level and PLT count of the patients. The prothrombin time (PT), activated partial thromboplastin time (aPTT), thrombin time (TT), and fibrinogen (Fib) concentration were detected before and after treatment, and the effect of leukapheresis on coagulation function of the patients was observed.
RESULTS: The volume of leukocyte suspension collected in a single treatment was 793.01±214.23 ml, the total number of WBCs subtracted was 353.25 (241.99-547.28)×109, the value of WBCs reduction was 86.98 (63.05-143.43)×109/L, the rate of WBCs reduction was 44.24 (28.37-70.48)%, decrease value of WBCs count was 65.73 (37.17-103.97)×109/L, decrease rate of WBCs count was (35.67±23.08)%, the amount of Hb lost was 17.36 (12.12-24.94) g, the value of Hb lost was 4.31 (3.01-6.12) g/L, decreased value of Hb was 4.80 (-1.25-9.33) g/L, total number of PLT lost was 222.79 (67.03-578.31)×109, the value of PLT loss was 54.45 (17.29-139.08)×109/L, and decrease value of PLT count was 26.00 (8.38-62.50)×109/L. Before and after a single treatment, the PT was 14.80 (13.20-16.98) s and 15.20 (13.08-16.90) s (z=-1.520, P>0.05), the aPTT was 35.20 (28.68-39.75) s and 35.40 (28.00-39.75) s (z=-2.058, P<0.05), the TT was 17.50 (16.30-18.80) s and 17.70 (16.70-19.10) s (z=-3.928, P<0.001), and the Fib concentration was 2.87±1.13 g/L and 2.64±1.03 g/L (t=7.151, P<0.001), respectively.
CONCLUSION: High-volume leukapheresis can improve the efficiency of leukapheresis while maintaining the relative stability of the patients' circulating blood volume. The degree of influence on the patients' Hb level, PLT count, Fib concentration, and comprehensive coagulation indicators reflecting the patients' intrinsic and cxtrinsic coagulation activity is within the body's compensation range.
