Challenge to Predict Mobilized Peripheral Blood Stem Cells on the Fourth Day of Granulocyte Colony-Stimulating Factor Treatment in Healthy Donors: Predictive Value of Basal CD34 Cell and Platelet Counts.

A longitudinal, prospective, observational, single-center cohort study on healthy donors was designed to identify predictors of CD34 cell mobilization on day 4 after granulocyte colony-stimulating factor (G-CSF) administration. As potential predictors of mobilization, age, sex, body weight, height, blood volume, WBC count, peripheral blood (PB) mononuclear cell count, platelet (Plt) count, and hematocrit and hemoglobin levels were considered. Two different evaluations of CD34 cell counts were determined for each donor: baseline (before G-CSF administration) and in PB on day 4 after G-CSF administration.

Basal CD34 Cell Count Predicts Peripheral Blood Stem Cell Mobilization in Healthy Donors after Administration of Granulocyte Colony-Stimulating Factor: A Longitudinal, Prospective, Observational, Single-Center, Cohort Study.

A longitudinal, prospective, observational, single-center, cohort study on healthy donors (HDs) was designed to identify predictors of CD34 cells on day 5 with emphasis on the predictive value of the basal CD34 cell count. As potential predictors of mobilization, age, sex, body weight, height, blood volume as well as white blood cell count, peripheral blood (PB) mononuclear cells, platelet count, hematocrit, and hemoglobin levels were considered. Two different evaluations of CD34 cell counts were determined for each donor: baseline (before granulocyte colony-stimulating factor [G-CSF] administration) and in PB after G-CSF administration on the morning of the fifth day (day 5).

Mobilization of hematopoietic progenitor stem cells in allogeneic setting with lenograstim by subcutaneous injection, in daily or twice-daily dosing: a single-center prospective study with historical control.

Background: Although the mobilization of hematopoietic progenitor stem cells from healthy donors (HDs) using granulocyte-colony-stimulating factor is widely used, the ideal method for the administration of the cytokine has not yet been determined.

Study Design And Methods: Seventy-five consecutive HDs received lenograstim (LENO) as mobilization agent. LENO was given subcutaneously at a dose of 10 µg/kg in a once-daily dose (ODD) every 24 hours.

Tolerability and efficacy of busulfan and fludarabine as allogeneic pretransplant conditioning therapy in acute myeloid leukemia: comparison with busulfan and cyclophosphamide regimen.

Background: The aim of this study was to compare safety and efficacy of the association of busulfan with cyclophosphamide (BuCy2) versus busulfan and fludarabine (BuFlu) as a conditioning regimen in allogeneic hematopoietic progenitor cell transplantation (allo-HPCT) in patients with acute myeloid leukemia (AML).

Patients And Methods: A total of 65 consecutive patients who received an allo-HPCT from Human Leucocyte Antigen-matched sibling donors were analyzed. The conditioning was BuCy2 in 48 patients and BuFlu in 17 patients.
